Innis, Neil Richard. "Synthesis and characterization of BxC films deposited via CVD and PE-ALD." Electronic Thesis or Diss., Lyon 1, 2024. http://www.theses.fr/2024LYO10241.
Full textAbstract:
Les couches minces de carbures de bores (BxC) trouvent diverses applications en tant qu'absorbeurs et détecteurs de neutrons, céramiques réfractaires, armures et protection balistique. Ces applications sont possibles grâce à leur forte absorption des neutrons, à leur grande stabilité chimique et thermique, ainsi qu’à leur grande dureté. En outre, ils présentent un intérêt potentiel pour les industries des semi-conducteurs et de l'optoélectronique en raison de leur conductivité de type p et de leur large bande interdite accordable. En effet, l'absorption nucléaire, les propriétés mécaniques, électroniques et thermiques du BxC dépendent de la composition chimique de ces films, et en particulier du rapport bore-carbone (B/C). Les procédés conventionnels pour obtenir des films de BxC sont la pulvérisation magnétron ou le dépôt chimique en phase vapeur (CVD). Alors que la pulvérisation magnétron pose des problèmes de conformité des films déposés sur des dispositifs structurés, les procédés CVD conventionnels impliquent des températures supérieures à 800 °C pour déposer le BxC à partir de précurseurs d'hydrure ou d'halogénure de bore. Ces précurseurs présentent cependant de forts inconvénients, tels qu'une toxicité élevée et/ou des sous-produits corrosifs. En outre, le contrôle précis du rapport B/C, de l'épaisseur et de la conformité reste toujours un défi. Il faut enfin noter qu'il n'existe pas à ce jour de procédé de dépôt par couche atomique (ALD) pour le BxC. Cette thèse vise à déposer des couches minces de BxC sur des substrats métalliques et isolants, en particulier sur le Si(100), avec un contrôle de la composition et de l'épaisseur à basse température, à partir de précurseurs exempts d'halogénures. Deux voies chimiques sont étudiées, un procédé CVD thermique et un nouveau procédé ALD assisté par plasma. Les deux procédés utilisent du triéthlyborane (TEB) et du gaz H2, et résultent en dépôts de films minces amorphes de BxC hydrogéné. Le procédé CVD thermique utilise une approche efficace de plan d'expériences (DOE) pour six paramètres expérimentaux afin de produire des films minces de BxC, avec un rapport B/C de 1 à 4 et à une température de dépôt de 400 à 600 °C. Le procédé PE-ALD développé, quant à lui, est optimisé pour produire des films de BxC sur Si(100) maintenus entre 112 et 138 °C avec un taux de croissance contrôlé d'environ 0,45 Å/cycle. En outre, en faisant varier la puissance du plasma et le flux de H2, le rapport B/C peut être réglé entre 0,3 et 3Boron-carbon (BxC) thin films find diverse applications as neutron absorbers and detectors, refractory ceramics, and armours and ballistic protection. This is due to their high neutron absorption, high chemical and thermal stability, and superior hardness. Moreover, they are of potential interest in the semiconductor and optoelectronic industries due to p-type conductivity and a tuneable wide bandgap. The nuclear absorption, mechanical, electronic, and thermal properties of BxC depend on the composition of these films, typically, the boron-carbon (B/C) ratio. The conventional processes to obtain BxC films are either magnetron sputtering or chemical vapor deposition (CVD). While magnetron sputtering suffers with conformality of as-deposited films on structured devices, conventional CVD processes involve temperatures higher than 800 °C to deposit BxC from boron hydride or halide precursors. Such precursors come with challenges such as high toxicity and/or corrosive by-products. Furthermore, tuning of the B/C ratio, and achieving excellent thickness control and conformality is still a challenge. It must be noted that no atomic layer deposition (ALD) process exists for BxC. This thesis aims at depositing BxC thin films on metal and insulating substrates, with a focus on Si(100) with composition and thickness control at low temperatures from halide-free precursors. Two chemical routes are investigated, a thermal CVD process, and a novel plasma-enhanced ALD process. Both routes employ triethlyborane (TEB) and H2 gas and demonstrate the deposition of amorphous hydrogenated BxC thin films. The thermal CVD process employs an efficient design of experiments (DOE) approach to six experimental parameters to produce BxC thin films with a B/C ratio of 1 to 4 within a deposition temperature of 400 - 600 °C. The developed PE-ALD process, on the other hand, is optimised to produce BxC films on Si(100) kept between 112.5 - 138 °C with a controlled growth rate of about 0.45 Å/cycle. Moreover, by varying the H2 plasma power and flux, the B/C ratio can be tuned from 0.3 to 3

Full textAbstract:
Equivocation was introduced by Shannon in the late 1940’s in seminal papers that kick-started the whole field of information theory. Much ground has been covered on equivocation’s counterpart, channel capacity and in particular, its bounds. However, less work has been carried out on the evaluation of the equivocation of a code transmitted across a channel. The aim of the work covered in this thesis was to use a probabilistic approach to investigate and compare the equivocation of various codes across a range of channels. The probability and entropy of each output, given each input, can be used to calculate the equivocation. This gives a measure of the ambiguity and secrecy of a code when transmitted across a channel. The calculations increase exponentially in magnitude as both the message length and code length increase. In addition, the impact of factors such as erasures and deletions also serve to significantly complicate the process. In order to improve the calculation times offered by a conventional, linearly-programmed approach, an alternative strategy involving parallel processing with a CUDA-enabled (Compute Unified Device Architecture) graphical processor was employed. This enabled results to be obtained for codes of greater length than was possible with linear programming. However, the practical implementation of a CUDA driven, parallel processed solution gave rise to significant issues with both the software implementation and subsequent platform stability. By normalising equivocation results, it was possible to compare different codes under different conditions, making it possible to identify and select codes that gave a marked difference in the equivocation encountered by a legitimate receiver and an eavesdropper. The introduction of code expansion provided a novel method for enhancing equivocation differences still further. The work on parallel processing to calculate equivocation and the use of code expansion was published in the following conference: Schofield, M., Ahmed, M. & Tomlinson, M. (2015), Using parallel processing to calculate and improve equivocation, in ’IEEE Conference Publications - IEEE 16th International Conference on Communication Technology’. In addition to the novel use of a CUDA-enabled graphics process to calculated equivocation, equivocation calculations were also performed for expanded versions of the codes. Code expansion was shown to yield a dramatic increase in the achievable equivocation levels. Once methods had been developed with the Binary Symmetric Channel (BSC), they were extended to include work with intentional erasures on the BSC, intentional deletions on the BSC and work on the Binary Erasure Channel (BEC). The work on equivocation on the BSC with intentional erasures was published in: Schofield, M. et al, (2016), Intentional erasures and equivocation on the binary symmetric channel, in ’IEEE Conference Publications - International Computer Symposium’, IEEE, pp 233-235. The work on the BEC produced a novel outcome due to the erasure correction process employed. As the probability of an erasure occurring increases, the set of likely decoded outcomes diminishes. This directly impacts the output entropy of the system by decreasing it, thereby also affecting the equivocation value of the system. This aspect was something that had not been encountered previously. The work also extended to the consideration of intentional deletions on the BSC and the Binary Deletion Channel (BDC) itself. Although the methods used struggled to cope with the additional complexity brought by deletions, the use of Varshamov-Tenengolts codes on the BSC with intentional deletions showed that family of codes to be well suited to the channel arrangement as well as having the capability to be extended to enable the correction of multiple deletions.

Att adoptera och att bli adopterad kan vara en påfrestande livserfarenhet så stöd och hjälp frånbarnhälsovården, socialtjänsten, sjukvården och barnpsykiatrin kan bli nödvändig. Föreliggandestudie är en registerstudie och omfattar 50 221 barn, varav 440 adopterade, som är födda mellan1994-2007 och folkbokförda i Uppsala län. Syftet med studien är att undersöka om det finnsnågra skillnader i kontakten med BVC för adoptivbarn jämfört med biologiska barn vad gällerantal mottagningsbesök, antal hembesök, MPR vaccinationer, skickade remisser till barnläkare,psykolog, ortoptist, audiolog och logoped samt om barnen genomfört syn-, hörsel ochspråkscreening och utfallet på dessa screeningar. Logistiska- och linjära regressionsanlysergjordes och en del korrigerades för ålder. Adoptivbarnen fick både färre hembesök och färremottagningsbesök. Det var också lägre andel adoptivbarn som blev vaccinerade mot MPR. Vadgäller remisser skickades för adoptivbarnen högre andel remisser till BHV-psykolog, ortoptistoch till logoped. De biologiska barnen genomförde synscreening i högre grad. Adoptivbarnenfick i högre grad utfall på syn- och hörselscreening. Adoptivbarnen får i lägre utsträckning änbiologiska barn ta del av viktiga komponenter i svensk barnhälsovård vilket kan leda till sämrehälsa för gruppen på lång sikt. Vården behöver bli mer jämlik för adoptivbarnen och för attkomma till insikt om varför dessa skillnader finns behövs fler studier på området.To adopt and to be adopted can be a distressing experience of life, and support from child healthcare, social services, health care and child psychiatry may be necessary. This study is aregister study and covers 50,221 children, of which 440 are adopted, born between 1994-2007 and registered in Uppsala län. The purpose of the study is to investigate if there areany differences in the contact with child health care for adopted children compared withbiological children as regards to the number of clinic visits, number of home visits, children whoare vaccinated with MMR, referrals to pediatricians, psychologists, orthoptist and speechtherapist and if the children perform the visual-, auditory-, and language screening and theoutcome of these screenings. Logistic- and linear regression analyzes were made and some werecorrected for age. The adoptees had both significantly fewer home visits and office visits than thebiological children. There were also a lower proportion of adopted children who were vaccinatedagainst MMR. The adopted children had significantly more referrals sent to the BHVpsychologist,the orthoptist and the speech therapist. Adopted children take a lesser part inimportant childcare components than biological children. This could lead to a worse health forthis group in the long term. The healthcare need to be more equal amongst children, and to getcloser to the cause of these differences more studies is needed.

Full textAbstract:
Bakgrund: Amning har många hälso-, ekonomiska och ekologiska fördelar för barn, föräldrar och samhället, men amningsstatistiken sjunker och beror ofta på otillräckligt amningsstöd. Syfte: att undersöka BVC-sjuksköterskors möjligheter och hinder för amningsrådgivning. Metod: Denna studie genomfördes med Critical Incident som metod. Sex bvc-sjuksköterskor i Sverige intervjuades om sina erfarenheter av att ge amningsrådgivning. Resultat: Resultatet delades in i två huvudincidenter utifrån syftet -Möjligheter och Hinder, med flera beteenden som kunde påverka incidenterna. Under Möjligheter kunde ses lyhördhet för kvinnans behov, att kunna ge enklare rådgivning och att ha tid för detta samt att kunna söka stöd hos andra. Beteenden som var hindrande för amningsrådgivning var bristande lyhördhet för kvinnans behov, att inte ha tillräckligt med djupare kunskaper eller tid, att inte samverka eller ha föräldraförberedande kurser. Konklusion: För att skapa möjligheter för individanpassad amningsrådgivning läggs stor vikt vid sjuksköterskans lyhördhet för kvinnan och barnets behov, förståelse för de förväntningar kvinnan har på amningen och att ha goda kunskaper samt tid. Hindrande för amningsrådgivningen är bristande lyhördhet för kvinnans behov, svårigheter att ge evidensbaserad information samt dåligt med tid. Samverkan mellan verksamheterna och att inte följa riktlinjer är en förbättringspotential för att stärka amningsrådgivningen.Background: Breastfeeding has many health-, economical and ecological benefits for child, parents and society, but statistics of breastfeeding are declining and are often due to insufficient breastfeeding support. Aim of the study: to examine child health care nurses’ possibilities and hindrance for breastfeeding counselling. Method: This study was conducted using Critical Incident as a method. Six child healthcare nurses in Sweden were interviewed about their experiences of providing breastfeeding advice. Results: The result was divided into two main incidents based on the aim, - possibilities and hindrance, with several behaviours that could affect the incidents. Under Possiblities a sensitivity for the woman’s needs, to be able to give simple breastfeeding advice, having time to give it and look for support when needed was seen. Behaviours that was a hindrance for breastfeeding counselling was a lack of sensitivity for the woman’s and child’s needs, to not have deeper knowledge or time, to not cooperate with others or not provide preparatory courses for parents. Conclusion: To create possibilities for individual breastfeeding counselling a sensitivity for the woman’s and child’s needs is essential, to have an understanding of the expectations the woman has and to have enough knowledge and time. Hindrance for breastfeeding counselling is a lack of sensitivity for the woman’s needs, difficulties to give evidence based information and not enough time. Cooperation between the different facilities and to follow the recommendations are potentials for improvement to strengthen the breastfeeding counselling.

Full textAbstract:
This historical commentary on the Metz Epitome, a late fragmentary account of Alexander's exploits, compares the work with the extant early Alexander historians. The sources of the anonymous author have much in common with the Cleitarchan historians, in particular, Diodorus Siculus and Quintus Curtius Rufus. Non-Cleitarchan elements in the text seem to reflect a certain affinity with a Hebraic tradition concerning Alexander. An examination of the author's methodology suggests that "epitome" is not an accurate description of the work in question. The anonymous author has achieved a unique portrait of Alexander and included information not found elsewhere. In view of its late authorship and the few new crumbs of historical fact it offers, the value of the Metz Epitome lies in its interpretation of Alexander's career rather than as a source for it.

Full textAbstract:
Questo lavoro si concentra sul fenomeno della superfluidità manifestato nell’4He, il primo superfluido scoperto. Dopo una breve introduzione storica, si passa all’esposizione della giustificazione teorica proposta da Landau. Poi si espongono le caratteristiche fisiche che sono coinvolte nell’origine di questo fenomeno. Dopodiché si illustra l’idrodinamica specifica per l’elio superfluido e si passano in rassegna le sue principali proprietà termodinamiche e idrodinamiche. Poi si approfondisce ulteriormente la proposta di Landau e si tratta delle quasiparticelle che possono formarsi nell’elio: i fononi e i rotoni.
Dopodiché si passa al capitolo che tratta delle relazioni tra la BEC e l’elio superfluido. Innanzitutto si parte una caratteristica
del superfluidi che permette di ricorre a un particolare modello di transizione. Da qui si sviluppa la giustificazione teorica che permette di associare una funzione d’onda macroscopica precisamente come nella BEC e le conseguenze di ciò. Subito dopo si evidenziano le differenze tra i due attraverso l’analisi della distribuzione di momento.
Il terzo capitolo espone le somiglianze tra i superfluidi e i superconduttori a partire dal nome. Si comincia spiegando cosa sono i superconduttori e le principali caratteristiche di questo stato. Successivamente vengono presentati i primi due modelli storici proposti per spiegare gli effetti misurati: l’equazione di London e il modello Ginzburg-Landau. Per entrambi verr`a evidenziato quanto questi modelli sono debitori nei confronti della fisica dei superfluidi.
In chiusura vengono trattati i vortici, punto di unione di tutti e tre i fenomeni trattati. Prima si spiega in cosa consistono i vortici nell’elio superfluido con una breve e coincisa trattazione dal punto di vista matematico del fenomeno. Poi si passerà brevemente ai vortici nella BEC. Infine si concluderà con i vortici nei superconduttori, le differenze e l’analogia tra questi e i
vortici nel superfluido.

Seminario para optar al grado de Ingeniero Comercial, Mención Administración de EmpresasNo autorizada por los autores para ser publicada a texto completo
El presente trabajo tiene como objetivo desarrollar el plan de negocios para la empresa Boxc que pretende incorporar, en su modelo negocio, la creación de tiendas de conveniencia mediante la utilización de containers que son transformados para estos fines. Para implementar estas tiendas o “C-stores” Boxc ha usado de respaldo una marca importante que es OK Market, por lo que mediante una franquicia de ésta, la empresa pretende administrar sus locales facilitando tareas importantes como lo son la logística y el posicionamiento ya establecido por esta gran cadena de tiendas de conveniencia. Dentro de las principales oportunidades que presenta la industria de las tiendas de conveniencia en nuestro país, podemos rescatar principalmente que el desarrollo que ha tenido el país ha cambiado a las personas y sus estilos de vida, donde factores como la inserción laboral femenina y los mayores tiempos de distancia de los hogares al trabajo, han causado que las personas cada vez tengan menos tiempo para permanecer y compartir en sus hogares junto a sus familias. En este sentido ingresan las tiendas de conveniencia, permitiéndoles a las personas realizar sus compras de una manera rápida, cómoda y de forma sencilla. La principal fortaleza que posee Boxc al operar estas tiendas con containers radica en la posibilidad de instalarse en lugares en donde el formato tradicional no puede acceder, a un costo mucho menor que un establecimiento normal y con una gran capacidad de adaptación al lugar en el que se requiere funcionar. Boxc deberá competir en base a diferenciación. Efectivamente la empresa está siendo diferente al utilizar esta nueva configuración de tiendas que pueden ser instaladas en lugares en los que la competencia no se encuentra. Además es importante ofrecer una variedad de productos que estén centrados en la calidad, ya que el consumidor chileno está cada vez más exigente y por lo mismo busca productos que cumplan con sus expectativas. También es clave la atención hacia los clientes, por lo mismo Boxc le dará alta relevancia a la preparación de sus trabajadores, para que entreguen un servicio de atención amable y cálido hacia el cliente, de manera que este vuelva a comprar en nuestras tiendas. Para el plan de implantación se especificaron los montos requeridos, las fechas y el financiamiento que espera recibir la compañía para la apertura de 6 tiendas para el año 2013 y lograr en 5 años tener en funcionamiento 30 locales. Además de lo anterior se hizo un análisis financiero con un horizonte a 5 años, estimando los ingresos y costos de operar estas tiendas, el pago por el concepto de la franquicia a OK Market y otros gastos en los que tendría que incurrir la empresa, lo que permite visualizar el atractivo de dar marcha a este emprendimiento.

Att bli förälder är en omtumlande upplevelse. För de föräldrar som vill ha stöd ska detta också finnas tillgängligt för att de med trygghet ska kunna möta barnets behov och stärka dess utveckling. BVC-sjuksköterskan har en central uppgift när det gäller att ge stöd till föräldrar med barn i åldrarna 0-6 år. Syftet med studien var att beskriva BVC-sjuksköterskors erfarenheter av att ge stöd i föräldraskapet. Metoden som användes var en kvalitativ innehållsanalys med induktiv ansats beskriven av Lundman och Hällgren Graneheim. Datainsamling gjordes genom intervjuer med fyra BVC-sjuksköterskor. Resultatet visade att BVC-sjuksköterskan upplevde att föräldrastöd var något som utfördes varje gång hon träffade föräldrarna. Genom att finnas till för familjen och stärka föräldrarnas egna resurser kunde hon stödja dem i föräldraskapet. Ett förändrat samhälle krävde dock en förändrad barnhälsovård och de resurser som gavs påverkade det stöd som kunde erbjudas föräldrarna.
Becoming a parent is an overwhelming experience. It is important to have support available for those who need it in order for parents to safely meet the needs of their child, and to strengthen the development of their child. The Child Health Nurse has a central role in supporting parents with childen aged 0-6 years. The aim of this study was to describe Child Health Nurses experiences of supporting parents. The method being used was a qualitative content analysis with an inductive approach described by Lundman and Hällgren Graneheim. The data was collected through interviews with four Child Health Nurses. The result shows that the Child Health Nurses experienced that parenting support was something which took place each time they met with the parents. By being there for the family and by strengthening the own resources of the parents, she could support their parenting. A changed society demanded a change in child health care and the conditions given influenced the support available for parents.

Full textAbstract:
Adoptioner i Sverige har minskat under de senaste åren. Barnen som adopteras är äldre än tidigare och har ofta medicinska problem. Forskning har visat att adoptivföräldrarna är osäkra i sin nya roll. Tankar och känslor väcks hos både föräldrar och barn i samband med adoptionen. Många adopterade barn kommer från svåra förhållanden med flera tidigare vårdare och får svårt att knyta an till sina nya föräldrar. Adoptivfamiljen kan ha behov av stöd från sjuksköterskan på barnavårdscentralerna (BVC). Dessvärre kan det vara svårt för BVC-sjuksköterskan att upprätthålla sin kompetens då antalet adoptivbarn är få. Föreliggande studie syftar därför till att beskriva BVC-sjuksköterskans stödjande förhållningssätt till familjer med adopterade barn. Åtta kvalitativa intervjuer genomfördes med distriktssköterskor och barnsjuksköterskor, som hade minst fem års erfarenhet av att arbeta på BVC. Materialet analyserades med kvalitativ innehållsanalys, enligt Lundman och Hällgren Graneheim. Efter analys framkom följande fem kategorier: Balans och obalans i anknytningen, Egen kompetens och strategier, Adoptivfamiljens styrkor och svagheter, Familjens behov och Barnets behov. I resultatet framkom att familjer med adopterade barn har ett stort behov av stöd från BVC-sjuksköterskan och speciellt i ett tidigt skede som adoptivförälder, vilket kan hjälpa att förebygga framtida problem. Stödet kan ges både genom enkla konkreta råd och praktiska strategier men även genom djupare stödjande samtal. BVC-sjuksköterskan bör vara lyhörd, inge trygghet och förtroende samt bemöta varje familj som unik. Besöken planeras efter varje familjs individuella behov. Familjens styrkor uppmärksammas och tillvaratas. Kliniska implikationer är att BVC erbjuder täta kontakter initialt, redan före adoptivbarnets läkarbesök, samt att BVC-sjuksköterskan vågar fråga hur familjen mår, hur de har det och ger familjerna den tid de behöver. BVC-sjuksköterskan bör vara följsam och uppmärksam på anknytningen mellan barnet och föräldrarna. Vi ser ett behov av fortsatt forskning kring BVC:s möte med adoptivfamiljen. Det finns även behov av vidare forskning utifrån adoptivföräldrarnas erfarenheter av att få ta emot stöd från BVC.

Full textAbstract:
The focus of this dissertation is the analysis of the music-related philosophical passages from the 5th century B.C. to the 2nd century B.C. It aims to provide a multifaceted view towards music as a cultural phenomenon, which is based primarily on the philological and culturological explorations instead of the technical-musicological approach. The texts from our selected period attest that mousikē had an extremely broad conceptualisation which led to the attribution of the different, sometimes completely opposite value: from an insignificant performative practice to an activity which corresponds to the divine laws and directly affects the human soul. The discussed testimonia provide evidence of defining music both as an exclusively acoustic phenomenon and as a philosophically significant concept that oversteps the sonic definition. Our sources clearly demonstrate that mousikē was a polysemous term: it was understood as an interdisciplinary form of art (as the arts of the Muses), though it was also used to indicate the exclusively instrumental music or a philosophical concept, which does not necessarily define sound as its essential quality. The aim of this dissertation is to clarify the arguments behind each of these positions, to analyse whether such different modes of conceptualisation are compatible among themselves, and to see how they fit together into explaining what was understood as music in Antiquity. In this thesis we explore the conceptual framework of mousikē and analyse what enabled the musical thought to be worthy of the attention of the greatest philosophical minds. We will demonstrate that it was not the sound or the artistic practices that were central in the philosophical thought on music, but instead the embedded structural qualities that have correspondence to the universal proportions of the cosmic world and which are perceptible to the listeners through the medium of sound.

Sammanfattning Syftet med studien var att beskriva BVC-sköterskors upplevelse av telefonrådgivning. Studien genomfördes som en semistrukturerad intervjustudie och hade deskriptiv design. Tio BVC-sköterskor inom primärvården intervjuades. Materialet analyserades med kvalitativ innehållsanalys. Resultatet visade att telefonrådgivning inom BVC krävde vissa egenskaper av BVC-sköterskan för att kunna ge god omvårdnad och exempel på detta var god kommunikationsförmåga, ett öppet sinne och lång erfarenhet. Vidare beskrev BVC-sköterskorna att de via telefonen försökte ge råd och information till föräldrarna för att skapa möjligheter för föräldrarna att själva ta ansvar och fatta beslut. BVC-sköterskan fanns som en resurs när det uppkom frågor och problem. Genom att god relation och god kännedom fanns mellan föräldrarna och BVC-sköterskan, upplevde respondenterna att bedömningen via telefonen underlättades. Problem med telefonrådgivningen beskrevs av deltagarna och det kunde röra bristande kommunikationsförmåga och svårigheter hos föräldrar att konkretisera problemet via telefonen. BVC-sköterskorna beskrev att de styrde sitt eget arbete och de beskrev att de hade möjlighet att boka in besök på mottagningen när problem uppkom vilket ökade tryggheten hos BVC-sköterskan. Slutsatsen är att BVC-sköterskorna upplevde sitt arbete med telefonrådgivning som en extra funktion och ett hjälpmedel i arbetet på BVC. Att använda telefonen i arbetet ökade BVC-sköterskans möjlighet att stötta föräldrar. Nyckelord: Barnhälsovård, Distriktssköterska, Telefonrådgivning.

Abstract Jerfström, M. (2013). Mission overweight and obesity – how do child-care centers operate? C-thesis in Public Health. Faculty of Health and Occupational Studies. University of Gävle. The main objective of the study was to examine how and with what methods child-welfare centers work to prevent overweight and obesity among children. Another objective was to see if the work was based on the Guidelines issued by the National Board of Health and Welfare. The methodology of the study was a descriptive design in a quantitative approach and the study group was nurses working at different child-welfare centers in a particular Swedish county. Data were analyzed by descriptive statistics. The results of the study showed that simple advices during individual conversations held on several occasions were the most widely used approach for prevention of overweight and obesity. The nurses did not follow the National Board of Health and Welfare Guidelines and pointed out the lack of specific knowledge in the subject. The conclusion was that there could be a need for new procedures and working methods in preventive work. This could be achieved in collaboration with other professions to supplement the lack of knowledge among the nurses. Keywords: child-welfare centers, overweight, obesity, prevention

Amningsfrekvensen har i Sverige successivt minskat för varje år och statistik visar kortare amningstid idag än för tio år sedan. Bröstmjölk är den ideala födan för barnet under de första sex månaderna. Den skyddar barnet mot ohälsa samt ökar överlevnaden. En betydelsefull del av arbetet för BVC-sjuksköterskorna är stödja och främja amning samt uppmuntra till upprätthållande av amning. Syftet med studien var att undersöka BVC-sjuksköterskors erfarenhet av amningsrådgivning. En kvalitativ forskningsmetod med deskriptiv design och induktiv ansats har använts. Specialistsjuksköterskor som arbetade på BVC intervjuades för besvarande av studiens syfte. Intervjumaterialet bearbetades med kvalitativ innehållsanalys. I resultatet framkom tre kategorier: Amningsrådgivningen baseras på riktlinjer, Behov av individanpassat stöd och Svårt och tidskrävande med amningsrådgivning. I studien framkom det att samtliga BVC-sjuksköterskor använde riktlinjer i amningsrådgivningen samt kompletterade dessa med annan kunskap och litteratur. BVC-sjuksköterskorna gjorde en individuell anpassning av amningsrådgivningen för att tillgodose mödrarnas personliga önskemål. BVC-sjuksköterskorna beskrev amningsrådgivningen som svår och tidskrävande. Resultatet av denna studie bidrar till insikt i vikten av kontinuerligt uppdaterade och förbättrade amningsriktlinjer samt ger en förståelse för BVC-sjuksköterskornas svårigheter med amningsrådgivningen. Studien kan också bidra till en ökad medvetenhet hos BVC-sjuksköterskorna av mödrarnas behov av individanpassad amningsrådgivning.The breastfeeding rate has gradually declined in Sweden every year and statistics show shorter breastfeeding today than ten years ago. Breast milk is the ideal food for the baby during the first six months. It protects the baby against illness and increase survival. A significant part of the work for the nurses at child health service is to support and promote breastfeeding and encourage the maintenance of lactation. The aim of the study was to investigate the child health service nurses' experience of breastfeeding counseling. Qualitative research with descriptive design and inductive approach has been used. Specialist nurses working in child health service were interviewed for answering the study's purpose. The interview data were processed using qualitative content analysis. The results revealed three categories: Breastfeeding counseling based on guidelines, Need for personalized support and Difficult and time consuming with breastfeeding counseling. The study revealed that all child health service nurses used guidelines in breastfeeding counseling and supplemented these with other knowledge and literature. Nurses at child health service made an individual adjustment of breastfeeding counseling to meet the mothers' personal preferences. The child health service nurses described the breastfeeding counseling as difficult and time-consuming. The results of this study contributes to the understanding of the importance of continuously updated and improved breastfeeding guidelines, and provides an understanding of the child health service nurses' difficulties with breastfeeding counseling. The study may also contribute to an increased awareness for the child health service nurses, of the mothers' need for individualized breastfeeding counseling.

CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOA principal dificuldade dentro do domínio B2C está em aumentar a utilidade da WWW para o comércio eletrônico através da melhoria das possibilidades oferecidas ao consumidor. Apesar de a WWW permitir ao comprador ter acesso a uma grande quantidade de informação, obter a informação do fornecedor certo que venda o produto desejado a um preço razoável, pode ser uma tarefa muito custosa. Uma das formas de melhorar essa situação é através do uso de agentes inteligentes de busca de informação, isto é, agentes de compra, que auxiliam os compradores a encontrar produtos de seu interesse. Para que isso ocorra esbarra-se em uma dificuldade inerente à própria WWW: a mistura da linguagem natural, imagens e informação de layout de HTML são uma das maiores barreiras para a automatização do comércio eletrônico, pois a semântica da informação é somente compreensível por seres humanos. Desta forma espera- se conseguir agentes de compra mais eficientes quando associados ao uso de ontologias, e lojas virtuais que tenham anotações especiais que sigam uma ontologia. Nessa dissertação fazemos um estudo sobre as principais tecnologias envolvidas no desenvolvimento de ontologias em Ciência da Computação. Fazemos também um estudo de caso sobre a aplicação de ontologias dentro do domínio de B2C, visando assim avaliar o potencial e as dificuldades existentes para o desenvolvimento desse tipo de aplicação.
The main difficulty associated with the B2C domain is increasing the usefulness of WWW for the electronic trade through the improvement of the services provided to the consumer. Even though the WWW allows the buyer to have access to a great amount of information, to obtain the information from the right supplier that sells the desired product by a reasonable price can be a very expensive task. One of the ways of improving the web functionality is through the use of intelligent agents for search of information, that is, the introduction of purchase agents that aid the buyers to find products of their interest. For that to happen we need to overcome an inherent difficulty of the WWW: the mixture of natural language, images and layout information in HTML is one of the greatest barriers for the automation of the electronic trade, because the semantics of the information is only comprehensible for human beings. To solve this problem we hope to produce more efficient purchase agents by associating them to the use of ontologies, and virtual stores that have special annotations that follow ontologies. In the present dissertation we make a study of the main technologies related to ontologies development in computer science. We also develop a case study about the ontologies application to the B2C domain, seeking in this way to evaluate potential and existing difficulties for the development of this type of application.

It has a very well positioned brand and is recognized within the ten best Peruvian food restaurants nationwide according to the well-known Summum Awards. A business consulting report will be prepared, where the problems facing the organization will be identified and alternative solutions will be defined. To prepare this work, we have the collaboration of the members of the board of directors. Unfortunately, the founder and general manager of this restaurant, who gave all the initial facilities to prepare the report, passed away in September 2019. Several meetings have been held with the restaurant's administrator, with whom the presentation made to the board in January 2020 was reviewed, to present the closing information for the year 2019, which is the information that has been used for the development of this business consulting report, in coordination with the organization. The various problems of the company have been presented and discussed, mainly at the administrative, operational, marketing and financial levels. It has been determined that the main problems revolve around current poor business administration, which affects the entire company transversally. The declared profit in 2018 was close to 1% of sales revenue and in 2019 it was negative. This shows the crisis that this organization is going through. In this thesis, the solution alternatives have been defined to reverse the current situation of the restaurant, which are mainly focused on developing a marketing plan, regularizing debts and ordering the accounting accounts of the business. The estimated projection indicates that in the year 2020 an approximate margin of 15% of sales revenue will be generated, which represents approximately one million soles after taxes.

Syfte: Att undersöka på vilket sätt postpartum depression identifieras hos nyblivna föräldrar och på vilket sätt screening med EPDS och påföljande stödjande samtal tillämpas av distriktssköterskor tjänstgörande på BVC i Uppsala län. Metod: Samtliga 98 distriktssköterskor som arbetar med BVC i Uppsala län inkluderades i enkätstudien. Svarsfrekvens utgjorde 60%. Enkäten bestod av 35 frågor. Resultat: Studien fann att EPDS-användning bland BVC-sjuksköterskor var hög, 51 av 59 använde EPDS och visade, bland de som hade besvarat enkäten, att det fanns en signifikant skillnad mellan EPDS-användning och vilken kommun distriktssköterskor arbetade i, och att det fanns ett signifikant samband mellan EPDS-användning och erhållen utbildning. Det fanns inget signifikant samband mellan EPDS-användning och tillgång till handledning. Riktlinjer för screening fanns på de flesta arbetsplatser, dock enbart för svensktalande mödrar. Screening av icke svensktalande mödrar var bristfällig och något strukturerat sätt att identifiera pappornas sinnesstämnings fanns inte. De flesta distriktssköterskor erbjöd mödrar stödjande samtal vid utfall efter screeningen. Avsatt tid och tidpunkten för EPDS-screeningen och avsatt tid för och antal av stödjande samtal varierade något. De flesta distriktssköterskor hade valt att utföra screeningen och stödjande samtalen på mottagningen. Dokumentationen av screeningen och de följande åtgärderna varierade. Slutsats: EPDS och påföljande stödjande samtal tillämpades rutinmässigt av de flesta BVC-sjuksköterskor i Uppsala län. Rutin för screeningen av icke svensktalande mödrar och fäder saknades på merparten av BVC.

The expression system of recombinant proteins in insect cells/baculovirus (BEVS) was described and introduced in 1983 and since then has become a powerful tool for the production of recombinant proteins of biotechnological interest. This work studied the kinetics of Bac-to-BacR Baculovirus Expression System (Invitrogen ) used for the production of recombinant proteins, evaluating growth patterns and consumption of nutrients from Sf-9 insect cells infected with this commercial bacmid and determining the effect of viral inoculum. For this, Sf-9 cells grew at 29oC in T flasks containing 5 mL of SF-900 II medium or Schott bottles with working volume of 15 mL and orbital shaking at 90 rpm. UFLAG-286 cells were also tested at 29°C in TC-100 medium supplemented with 10% bovine fetal serum. The baculovirus used were the Autographa californica nuclear polyhedrosis virus (AcMNPV) as a wild baculovirus infection model, the bacmid extracted from DH10Bac bacteria and transposed with the transfer vector empty (pFastBac 1), called Bac sprec and the bacmid recombinant AcNPV with the GUS coding sequence of the gene β- glucuronidase, used as a standard for transposition experiments and transfection. Cells were infected at different times (TOI), on the initial phase, the exponential phase or stationary phase of cell growth, and with different multiplicities of infection (MOI) (0.01, 0.1, 1 and 10). It was observed that the MOI does not influence the viral replication, because even with the low MOI the cell growth was completely inhibited. TOI had already affected the production of total cell proteins, and infection in the early exponential phase was that obtained the highest number of total proteins. The supplementation of the cultivation with Bac sprec with serine and glutamine did not lead to increased viral production. The supernatant of cultures infected with Bac sprec was able to inhibit cell death where there was induction of apoptosis by terbutyl, indicating contain some protein with anti-apoptotic activity. This effect was not observed on wild baculovirus.

O objetivo deste trabalho foi estudar os parametros cineticos do sistema Bac-to-BacR Baculovirus Expression (Invitrogen ) utilizado para a producao de proteinas recombinantes, avaliando os padroes de crescimento e consumo de nutrientes de celulas de inseto Sf-9 infectadas com este bacmideo comercial e determinando o efeito do inoculo viral. Para isso celulas Sf-9 foram cultivadas a 29oC em frascos T contendo 5 mL de meio SF-900 II, ou em frascos Schott com volume de trabalho de 15 mL e agitacao orbital a 90 rpm. Celulas UFLAG-286 tambem foram testadas a 29oC em meio TC-100 suplementado com 10% de soro fetal bovino. Os baculovirus utilizados foram o Autographa californica nuclear polyhedrosis virus (AcMNPV), como modelo de infeccao de baculovirus selvagem, o bacmideo extraido da bacteria DH10BacTM e transposto com o vetor de transferencia vazio (pFastBac 1), chamado de Bac sprec e o bacmideo recombinante AcMNPV-GUS com a sequencia codificante do gene β glucuronidase, utilizado como um padrao para experimentos de transposicao e transfeccao. As celulas foram infectadas em diferentes momentos (TOI), seja na fase inicial, na fase exponencial ou fase estacionaria do crescimento celular e com diferentes multiplicidades de infeccao (MOI) (0,01; 0,1; 1 e 10). Observou-se que o MOI nao influencia a replicacao viral, pois mesmo com baixo MOI o crescimento celular foi inibido. Ja o TOI teve influencia na producao de proteinas totais da celula, sendo que a infeccao no inicio da fase exponencial foi que obteve maior numero de proteinas totais. A suplementacao do cultivo de Bac sprec com serina e glutamina nao levou a uma maior producao viral. O sobrenadante de cultivos infectados com o Bac sprec foi capaz de inibir a morte celular onde houve inducao de apoptose por terbutil, indicando conter alguma proteina com atividade antiapoptotica. Este efeito nao foi observado com o baculovirus selvagem.

Full textAbstract:
Several twentieth century archaeological expeditions to Lower Nubia recovered the skeletal and cultural remains of C-Group populations mainly from cemetery sites between Shellal and the Second Cataract. Along with the remains of the more or less contemporary Pangrave and Kerma peoples, the C-Group archaeological sequence was assigned to the Middle Nubian Period which lasted from the Sixth to the Eighteenth Egyptian Dynasties and is dated from ca. 2200 B.C. to ca. 1500 B.C. Conflicting interpretations of C-Group socioeconomic conditions are inevitable since no systematic analysis of the data resulting from the excavations of Middle Nubian cemeteries has ever been undertaken. In an attempt to assess the extent of C-Group economic contact with the Egyptians and to resolve the issue of possible growing social differentiation within the C-Group community, a quantitative analysis of the mortuary remains from fifteen C-Group cemeteries was undertaken. The results indicate that the flow of a small number of Egyptian artefacts into Lower Nubia was relatively constant and that contact between Lower Nubians and Egyptians was probably quite limited. Egyptian portrayals of constant fluctuation in Egyptian-Nubian political relations do not correspond with the evidence from the Nubian archaeological record. The analysis also indicated that economic inequality amongst the Middle Nubian population was present in each date category and tended to increase over time. Socioeconomic differences were greatest during the middle of the Second Intermediate Period. These findings indicate that the Middle Nubian socioeconomic system tolerated increasingly conspicuous differences amongst its members. They are not consistent with the hypothesis that no increase in differential access to burial resources occurred between ca. 2100 and ca. 1550 B.C. and that C-Group social and economic conditions remained virtually unchanged throughout their 800-year history.

The work of people with disabilities (PCD) has been, historically, the struggle of the social movements of this segment under the discourse of social inclusion. We understand that the forms of response to the needs of the PCD are linked to the different models of corporate organization and that, in the capitalist mode of production, does not escape the logic of productivity and extraction of surpluses necessary for the accumulation of capital. In 2012, the BPC Work Program was created, which aims to promote access to professional qualification and the labor market for beneficiaries of the Benefict of Continuous Provision (BPC). The present dissertation aims to analyze the insertion in the labor market of disabled people, beneficiaries of BPC, through this Program. To do so, we undertake a theoretical approach in order to understand the economic and political ground in which the object is inserted, as well as to analyze issues specific to the PCD. We take as a historic mark the crisis of capital and the bourgeois responses to the resumption of growth, with direct implications in the world of labor under productive restructuring and social policies, considering also the current conjuncture of counterreforms. In the Brazilian particularity, we infer how the ideals of social-liberalism were impregnated in social policies, in particular in the politics of Social Assistance, during the period of the PT governments, being the Program in study aligned to such perspective. About people with disabilities, we approach the questions about their denomination and insertion in social relations in different societal contexts, as a preamble to comprehend the relationship of this segment with the world of work. The methodology adopted prioritized the bibliographic and documentary study, which took place in the sense of understanding the contradictions and mediations intrinsic to this object. From the critical-dialectical approach, through the Marxian categories, we seek to capture it from its appearance. Based on information from the Ministries of policies involved in the implementation of the Program (social assistance, education and labor), as well as from the National Institute of Social Security, we have taken a course that has allowed us to make important approaches to the Program. The contradictions that permeate social policies and current downward trends in the face of the offensive of neoliberal orthodoxy imply a great deal in the applicability of the Program and in what it means the beneficiaries of the BPC are considered capable of producing and then called to be inserted in the job market. Therefore, in discussing the autonomy of PCDs through work and stressing the relationship between social assistance and labor, the Program in question puts issues relevant to the demands of the PCD on the agenda and, at the same time, is functional to capital, in a peculiar way in times of crisis, because it ends up being a gateway to the BPC, when it stimulates them to enter the labor market, to become self-sufficient citizens, emancipated in appearance, with implications for the composition of relative overpopulation and lump-proletariat.
O trabalho das pessoas com deficiência (PCD) tem sido, historicamente, bandeira de luta dos movimentos sociais desse segmento sob o discurso da inclusão social. Compreendemos que as formas de resposta às necessidades das PCD estão vinculadas aos diferentes modelos de organização societária e que, no modo de produção capitalista, não foge à lógica de produtividade e extração de excedentes necessários à acumulação do capital. Em 2012, foi criado o Programa BPC Trabalho, o qual visa a promoção do acesso à qualificação profissional e ao mercado de trabalho aos beneficiários do benefício de prestação continuada (BPC). A presente dissertação tem como objetivo analisar a inserção no mercado de trabalho das pessoas com deficiência, beneficiárias do BPC, através desse Programa. Para tanto, empreendemos um caminho teórico em busca de compreender qual o solo econômico e político no qual está inserido o objeto, além de analisar questões específicas às PCD. Tomamos como marco a crise do capital e as respostas burguesas para retomada do crescimento, com implicações diretas no mundo do trabalho sob a reestruturação produtiva e para as políticas sociais, considerando ainda a conjuntura atual de contrarreformas. Na particularidade brasileira, inferimos como os ideais do social-liberalismo foram impregnados nas políticas sociais, em particular na política de Assistência Social, durante o período dos governos petistas, estando o Programa em estudo alinhado a tal perspectiva. Em relação às pessoas com deficiência, nos aproximarmos das questões sobre a sua denominação e inserção nas relações sociais nos diferentes contextos societários, como preâmbulo para compreendermos a relação desse segmento com o mundo do trabalho. A metodologia adotada priorizou o estudo bibliográfico e documental, que se deu no sentido de entender as contradições e mediações intrínsecas ao objeto. A partir da abordagem crítico-dialética, mediante as categorias marxianas, buscamos capturá-lo partindo de sua aparência. Tendo como fontes informações dos Ministérios das políticas envolvidas na execução do Programa (assistência social, educação e trabalho), bem como do Instituto Nacional de Seguro Social, trilhamos um percurso que nos permitiu aproximações importantes a respeito do Programa. As contradições que perpassam as políticas sociais e as tendências de retrocesso na atualidade, frente à ofensiva da ortodoxia neoliberal, implicam sobremaneira na aplicabilidade do Programa e no que significa os beneficiários do BPC serem considerados capazes de produzir e, então, chamados a se inserir no mercado de trabalho. Portanto, o Programa em questão, ao pôr em debate a discussão sobre autonomia das PCD através do trabalho e ao tensionar a relação entre Assistência Social e trabalho, põe na ordem do dia questões pertinentes às demandas das PCD e, concomitantemente, é funcional ao capital, de forma peculiar em tempos de crise, pois acaba sendo uma porta de saída do BPC, quando estimula que esses se insiram no mercado de trabalho, que se tornem cidadãos autossuficientes, na aparência emancipados, com implicações na composição da superpopulação relativa e lumpemproletariado.

Argomento principale delle note seguenti è la descrizione del fenomeno della superfluidità in relazione al condensato di Bose-Einstein. Ai fini della trattazione saranno fatti riferimenti ad importanti risultati teorici e sperimentali, utili a fornire una panoramica il più possibile completa senza indugiare in formalismi e dettagli (comunque presenti in minima parte) che, per quanto interessanti, bisognerebbero di ulteriori approfondimenti. Verrà quindi fatto accenno alla teoria dello spettro eccitato di Bogoliubov, la quale, a partire dalle interazioni fra particelle, fornisce modelli e previsioni per i gas di Bose-Einstein applicabili al concetto di superfluidità; verranno introdotte le equazioni di Gross-Pitaevskii, la cui forma dipendente dal tempo descrive l’evoluzione temporale della funzione d’onda del condensato; sarà dedicato un intero capitolo al fenomeno della superfluidità, con accenno alle teorie di Landau ed al formalismo di base per la idrodinamica quantistica, fondamentale per lo studio del modello a due fluidi e per l’analisi sul decadimento dei fononi.

Full textAbstract:
Den nya ekonomin innebär ett mer dynamiskt klimat för företagen. Detta ställer nya krav på företagens anpassningsförmåga. Outsourcing är ett sätt att bemöta ovan nämnda flexibilitetskrav. E-handel är en annan del av den nya ekonomin. Allt fler konsumenter upptäcker fördelar med att"shoppa on-line". En aktuell fråga är hur företagen skall ta betalt av sina kunder. I Sverige är det CD- skivor, böcker, datorer och datorrelaterade produkter som stått för den största delen av näthandeln. När det gäller ovanstående produkter rör det sig om relativt billiga produkter och ganska stora betalningsvolymer. Det ställs alltså krav på företagen att kunna hantera ett relativt stort antal betalningar redan från start. Många ”näthandelsföretag” är dessutom nystartade, vilket kan innebära att man inte har råd att köpa in dyra faktureringssystem etc. Man vill istället ofta koncentrera sig på sin kärnkompetens och komma i gång så fort som möjligt till lägsta möjliga kostnad. Ett sätt att undvika de stora fasta kostnader, vilka investeringar i faktureringssystem kan medföra, är att outsourca faktureringsfunktionen. Outsourcing medför att verksamheten kan drivas med löpande kostnader istället för fasta, vilket borde kunna bidra till att lönsamhet kan uppnås snabbare i företagen. Outsourcing av faktureringsfunktionen borde således vara av stort intresse för många av företagen i den nya ekonomin. Denna studie analyserar de problem och möjligheter som uppstår när näthandelsföretag (B2C) bestämmer sig för att outsourca faktureringsfunktionen.

Full textAbstract:
Tetrahydroisoquinolines (THIQs) are found in a wide range of natural products and compounds with biological activity. This thesis describes the methodology of deprotonation‒substitution as an efficient route to 1-substituted THIQs and 3-substituted THIQs. This methodology was developed by using organolithium and organomagnesium chemistry. Firstly, methods were developed for the lithiation–substitution of tetrahydroisoquinolines by carrying out in situ ReactIR spectroscopic monitoring of deprotonation reactions. Moderate to high yields of products were obtained under the optimum reaction conditions. The lithiation‒substitutions of tetrahydroisoquinolines A were carried out. This chemistry was applied to a short synthesis of the alkaloids (±)-dysoxyline and (±)-crispine A. The lithiation–substitution of N-Boc-3-phenyltetrahydroisoquinoline B was also investigated. Lithiation was found to occur with approximately a 2:1 ratio at C-1 to C-3. NMR studies and DFT analysis were carried out in order to calculate the ratio of the two rotamers of B. Investigations have also focused on N-Boc-3-cyanotetrahydroisoquinoline and N-Boc-2-cyanopyrrolidine. High enantioselectivities of the forming products could be obtained from the sequence of deprotonation–substitution of these compounds at –104 ºC using magnesium bases. Altering the solvent was shown to have a large impact on the yield and enantioselectivity of the products.

Bakgrund och problemformulering: Många kvinnor har bestämt sig för att amma innan förlossningen. Tidig hemgång från BB-avdelning gör att BVC-sköterskan har ett stort ansvar att stödja nyblivna mammors amning. Studier visar att BVC ibland ger bristfällig och felaktig information om amning och mammor upplever amningsstödet från BB bättre än stödet från BVC. Med bakgrund av detta utformades studiens syfte för att beskriva mammors upplevelse av amningsstöd på BVC.Syfte: Att beskriva mammors upplevelse av amningsstöd.Metod: Öppna intervjuer genomfördes med åtta mammor. Alla hade påbörjat amning men ammade under olika lång tid. Samtliga mammor hade deltagit i basprogrammet på BVC. En kvalitativ innehållsanalys gjordes av de transkriberade intervjuerna.Resultat och diskussion: Studiens resultat visade att mammor har stort behov av individuellt stöd vid amning. Mammorna berättade om bra och mindre bra erfarenheter i mötet med BVC-sköterskan. Det som framgick av studien var att tid, individuellt stöd och uppmuntran att tro på sin egen förmåga från BVC-sköterskan var det viktigaste för mammorna. De mammor som inte fick stödet de önskade kände sig utlämnade och ensamma i sin situation, de kände att de inte dög som mammor. I de berättelser där mammorna fick stöd kände de sig stärkta. När mammorna inte kände stöd från BVC-sköterskan förstärktes deras känsla av oduglighet. Slutsatsen är att BVC-sköterskans amningsstöd är viktigt men kunskaper om amning och samtalsmetodik behöver förbättras och utvecklas för att skapa vårdande relationer.Program: Specialistsjuksköterskeutbildning med inriktning mot distriktssköterska

Mobile application ('apps') development is a recent pandemic phenomenon; companies that are not associated with mobile technologies are noticing it and want to develop their own mobile apps. However, these companies do not realize that they need to have a mobile strategy in place, just like their IT strategy. Mobile technology is a new paradigm for businesses. The mobile device is emerging as a powerful sales channel and marketing medium, which these businesses must strategize and plan for. Companies need to be equipped with a framework within which they can develop marketing initiatives through mobile technologies. The world is reaching a point where developing a viable mobile strategy is an imperative for small and large businesses to enable their long term growth and sustenance. Recently, the iPhone and its app store have created a vibe in industry with almost 1 billion mobile apps being downloaded from the iphone app store by July 2009. However, many marketers still doubt iPhone's reach to a larger, and, more importantly, a targeted audience. Also, there is increasing complexity with a variety of architectures, platforms and processes being adopted by each player, for example: iPhone App store, Blackberry App world, Palm's App Catalog, Microsoft's Windows Mobile Marketplace, Nokia's ovi, Google Android Market and more in the pipeline by various players in the market ecosystems, mainly device manufacturers-Samsung, LG, Motorola-as well as service providers - AT&T, T-Mobile and 02, to name a few. The purpose of this thesis is to analyze the mobile application development framework and its implications for marketers, and try to answer some of the questions regarding mobile application development strategy. The author will attempt to address the lack of knowledge that companies have available today when deciding whether to develop mobile applications for marketing and how to choose which platform(s), and provide a reference document that companies can use in order to be successful.

The transmitter is similar as that using BPSK except from the sub-carrier modulation. But the receiver design is totally different because the BOC signal has different performance. The acquisition methods of BOC signal have been discussed such as the single-side BPSK-like, double-sides BPSK-like and hybrid processing methods, which can restrain side-peak and eliminate ambiguities. The three acquisition process principles and their performances include arithmetic complexity are described, compared and simulated using MATLAB.

Full textAbstract:
Dagens samhälle har blivit mer och mer digitaliserat vilket har lett till att förändrade köpbeteende har vuxit fram hos kunderna. Genom den digitala utveckling har kundernas tillgång till information ökat kraftigt, vilket gör att kunderna är mer välinformerade än någonsin. Det ökar konkurrens mellan de olika aktörerna på marknaden och leder till att driva på innovationstakten. För att lyckas med det räcker det inte längre att företagen fokuserar på teknisk utveckling utan de måste istället fokusera på att ta fram helt nya affärsmodeller. De nya affärsmodellerna bör i sin tur fokusera på att sätta användarna i centrum för värdeskapandet för att på så vis maximera användarnas upplevda värde. Frågeställningen som besvarats genom uppsatsen har därför varit att undersöka hur användarcentread affärsmodellinnovation kan bedrivas i ett B2C sammanhang. Syftet var sedan att ta fram ett ramverk för användarcentrerad affärsmodellinnovation. För att göra det utgick arbetet från uppfyllnad av användarnas behov för att på så vis säkerställa att användarcentrering uppnås. För att ta fram ramverket studerades relevant litteratur och sex olika fallföretag för att på så vis ta fram ett nytt analysverktyg som kan användas för att förstå och jämföra affärsmodellinnovation mellan olika företag. Det verktyget applicerades sedan på de olika fallen varpå en inbördes jämförelse genomfördes. Utifrån den jämförelsen kunde sedan en sammanställning av best practice av användarcentrerad affärsmodellinnovation tas fram. Utifrån jämförelsen kunde även konkreta insikter om hur företag som vill ställa om från en traditionell B2B-logik mot att istället bli en mer användar- och B2C-fokuserad verksamhet tas fram. Fallstudierna var av teoretisk och kvalitativ karaktär och baserades på i första hand av studier av teoretiska artiklar, årsredovisningar och kvalitativa intervjuer med innovationspersonal på fallföretagen. Den empiriska undersökningen visar att framgångsrik användarcentrerad affärsmodellinnovation tenderar att fokusera på innovation av kunderbjudande, kundrelationer och kanaler. Traditionella företag som är fokuserade på att göra affärer med andra företag tenderar däremot att fokusera på innovation av interna aktiviteter och resurser. För företag som vill skifta fokus i verksamheten från B2B till B2C användarcentrering bör därför ställa om den övergripande innovationsförmågan mot en mer erbjudande och kundorienterat innovationsstrategi. Det nya ramverket kan således användas rakt av för att applicera användarcentrerad affärsmodellinnovation i ett företag. Eller så kan ramverket omformas och anpassas efter andra kontexter än de som studerats i uppsatsen genom att använda andra eller fler exempel. Slutligen kan även de konkreta verktygen som satts samman och presenterats i uppsatsen användas separat för att övergripande analysera och förstå affärsmodellinnovation i företag eller hela branscher.Today's society has become more and more digitalized, which has led to that changes in purchasing patterns have emerged among customers. Through the digital development, customers' access to information has increased dramatically, which means that customers are more informed than ever. That development leads to increased competition between the various players on the market and an increase in the pace of innovation. To succeed, it is no longer enough that companies focus on technological development but must instead focus on developing new business models. The new business models in turn should focus on putting users at the center of the value creation to thereby maximize the users' perceived value. The question that is answered through this thesis has been how user centered business model innovation can be conducted in a B2C context. The aim then was to develop a framework for user-centric business model innovation. To make it work the thesis has been focusing on the fulfillment of the user needs, thus ensuring that the user centering is achieved. To develop the framework relevant literature and six different cases companies were studied, in order to create a new analysis tool that can be used to understand and compare business model innovation between companies. The tool was then applied to the various cases and the results were compared with each other. Based on the comparison a compilation of best practices of user- centered business model innovation could be compiled. Based on the comparison practical insights on how companies who want to switch from a traditional B2B logic to instead become a more user- and B2C-focused activities were identified and analyzed. The case studies were of theoretical and qualitative nature and based on primarily the study of theoretical articles, annual reports and interviews with staff working with innovation in the cases companies. The empirical study shows that successful user-centric business model innovation tends to focus on innovation of value propositions, customer relations and channels. Traditional companies that are focused on doing business with other companies, however, tend to focus on the innovation of internal activities and resources. For companies that want to shift the focus of the business from B2B to B2C should hence change the overall innovation capability towards more offers- and customer-oriented innovation strategies. The new framework can be used straight off to apply user-centered business model innovation in a company. Or the framework can be reshaped and adapted to different contexts than those studied in this thesis by using other or more examples. Finally, the concrete tools that are put together and presented in the thesis could be used independently to analyze and understand the overall business model innovation in companies or entire industries.

Dans le but de réduire le poids des véhicules, l'industrie automobile remplace de plus en plus la tôle par des matériaux composites à matrice polyester renforcée par des fibres de verre et chargée en carbonate de calcium. Ces composites sont généralement assemblés par collage. Ainsi, afin d'appréhender les mécanismes à l'origine de l'adhésion entre un adhésif polyuréthane modifié acrylique et différents composites BMC (Bulk Molding Compound), les deux matériaux ont été caractérisés. Différentes techniques d'analyse de surface complémentaires (MEB, ESCA, SIMS et TOFSIMS, SDL, mouillabilité) ont permis d'acquérir une bonne connaissance de la surface des BMC. En particulier, l'influence de la concentration et de la nature des démoulants internes du BMC (stéarate de calcium ou de zinc) a été mise en évidence tant sur les propriétés de surface que sur le comportement adhésif En effet, il est apparu que même en faible proportion les démoulants favorisent l'adhésion BMC/adhésif polyuréthane et améliorent le comportement des assemblages en vieillissement humide. Différentes hypothèses sont évoquées pour expliquer l'amélioration de l'adhésion liée à la présence du démoulant en surface, notamment la nature et le nombre de groupements de type COO en surface du composite et le rôle de connecteurs des molécules de stéarate.

Carbonized organic precursors such as wood, shells and some plant seeds are very porous. They are nanostructured and tend to be hard, but have pure mechanical properties as a result of their porosities. An attempt was made to carbonize an organic precursor to produce a bulk material with much less porosity for possible use in structural applications such as reinforcement in metal and polymer matrices. A bulk nanocarbon (BNC) material was synthesized using high energy ball milling and the carbonization of corn cob. Corn cob was mechanically milled for up to 20 hours by applying high energy ball milling to produce the milled powder. The milled powder was cold-compacted and carbonized at up to 1500°C to fabricate the BNC material. The material revealed both micro and nano-porosities; the porosities decreased with carbonizing temperature and hold time. Micropores were mostly closed for samples carbonized above 1300oC, whereas they formed interconnected network at lower carbonization temperatures. BNC has a young's modulus of 120 GPa, about ten times that of extruded graphite.Master of Science
Wood, shells, and plant seeds are examples of organic precursors. When organic precursors are carbonized, they can become very porous, nanostructured, and hard, but deliver pure mechanical properties because of their porosities. A selected organic precursor was carbonized, in an attempt, to produce a bulk material with much less porosity for possible use in structural applications such as reinforcement in metal and polymer matrices.

Full textAbstract:
In 1985, Prime Minister Margaret Thatcher declared publicity to be the ‘oxygen’ of terrorism. Speaking from within a climate of domestic terrorism, such a statement draws into question the nature of contemporary media coverage. The British Broadcasting Corporation, existing as a public sector broadcaster, occupies a unique position in the context of 20th and 21st century mass media. The BBC is central to the creation and direction of national and international news agendas, in the formation of worldwide public opinion, and the brand name and reputation hold connotations of honesty, accuracy and impartiality. It can therefore be positioned as a ‘a microcosm of some larger system or a whole society' (Gomm et al., 2000, p.99). Yet, the historical visual output of the organisation in relation to domestic terrorism emanating from the environment of the Troubles — a significant period in social, cultural, political, and media history — has never been subject to rigorous academic scrutiny. Grounded in the field of media and cultural studies, and drawing upon extensive archival research, this thesis investigates the representation of domestic terror by the BBC in news and documentary format over the three-decade period of 1968-1998 through two interpretive modes of textual analysis: content analysis and semiotics. Throughout, the representation of events is contextualised in relation to media theory, with the words and pictures broadcast by the BBC analysed. The framing of acts of terror as image events is considered, as well as the visual aesthetic, codes, and values, of news reports. Ultimately, this work argues that BBC coverage of the Troubles has clear and identifiable patterns and symbols. Initial outbreaks of violence, where no corresponding representational referents existed, trended towards the vivid and graphic. Gradually, however, there was an overt movement away from this form; with the notable exception of moments where a method of perception created a disjuncture to established means, coverage was dominated by generic media templates, the rhetoric of euphemism, a concerted lack of contextualisation, and empty symbolism of the absent image.

New evidence based methods are requested within the work of Child Health Care (CHC). The workload for nurses at the CHC centres is high and new interventions needs to be fast and simple to be implemented. The parent checklist CSBS-DP ITC is a screening tool which has been tested during the period 2015–2017 at eleven CHC centres in Uppsala. The aim with the method is early identification, assessment regarding child communication and language problems. The aim with this pilot study was to examine differences between nurses’ experiences and opinions on communication assessment at 18 months depending on which method they used, ITC or regular routine. A web based survey consisting mostly of multiple choice questions was sent to 35 nurses who has been using the ITC checklist and 58 nurses who has been working according to regular routine. The survey ultimately reached 76 people, and out of these 76 nurses 11 from each group filled in the survey (29%). The result showed statistical significant differences between the groups on two questions regarding nurses experience on having a structured method for assessment of communication and language and the nurses’ experiences on how confident they were in describing problems in development of communication and language. The nurses who used the ITC assessment generally felt more secure in their assessment of communication and language, motor skills, play development and growth.Nya evidensbaserade metoder efterfrågas inom barnhälsovårdens arbete. Då sjuksköterskorna på barnavårdscentralen (BVC) idag har hög arbetsbelastning behöver nya interventioner vara enkla och snabba att genomföra för att kunna implementeras. Föräldraformuläret CSBS-DP ITC är en screeningmetod som under perioden 2015 till 2017 har använts på elva barnavårdscentraler i Uppsala. Syftet med metoden är att tidigt identifiera barn med misstänkta kommunikationssvårigheter för att kunna remittera dem vidare för bedömning och eventuell intervention. Denna pilotstudie syftar till att undersöka om det finns skillnader i BVC-sjuksköterskors upplevelse av kommunikationsbedömning vid 18-månadersbesöket beroende på om de använt ITC- formuläret eller inte. En webbenkät bestående av främst flervalsfrågor skickades till 35 sjuksköterskor som använt föräldraformuläret ITC samt 58 sjuksköterskor som arbetat enligt ordinarie rutin. Enkäten nådde 76 personer. Av dessa var det 11 deltagare från varje grupp som fyllde i enkäten (29%). Resultatet visade ett p-värde på under 0,05 vid två frågor vad gällde sjuksköterskornas upplevelse av att ha en strukturerad metod vid kommunikations- och språkbedömningen samt sjuksköterskornas upplevelse av hur trygga de känner sig i att beskriva avvikelser hos barnet vad gäller kommunikations- och språkbedömningen. Sjuksköterskorna som använt ITC-formuläret kände sig generellt säkrare i sin bedömning av kommunikation och språk, motorik, lekutveckling samt tillväxt, än sjuksköterskorna som arbetat enligt ordinarie rutin.

Full textAbstract:
Les maçonneries en BTC (Blocs de Terre Comprimée) permettent de construire des habitats individuels à un faible coût environnemental (et économique pour les pays du sud) car on utilisa des matériaux locaux. De plus cette démarche a un impact socioéconomique positif puisqu'elle favorise le travail humain direct de construction contrairement à la filière actuelle basée sur l'industrialisation de la production du matériau. L'architecture utilisée est adaptée au matériau qui ne doit travailler qu'en compression. Cette thèse s'inscrit dans le contexte de formulation du comportement en compression des maçonneries en BTC. Nous avons pour cela effectué une étude de comportement des maçonneries en BTC sous compression simple verticale. Le BTC est la composante principale de la maçonnerie. Ainsi une analyse de son comportement en compression simple est faite. Les différentes procédures d'essais de compression utilisées jusqu'à maintenant sur BTC sont présentées et critiquées. Nous arrivons à la conclusion que l'essai sue demis blocs maçonnés (l'un au dessus de l'autre) est pertinent. Il est aussi démontré que l'essai de flexion en trois points peut donner la résistance en compression de BTC avec une précision de l'ordre de 20%. La seconde composante de la maçonnerie est le mortier de terre (à plus de 88% en poids sec de terre) stabilisé au ciment. La littérature n'apporte que peu d'information sur ces types de mortier. Il en ressort l'impossibilité d'utiliser le maniabilimètre AFNOR, la possibilité d'utiliser le cône d'Abrams et la nécessité d'appréhender le comportement d'interface BTC-mortier. Enfin des échantillons de maçonnerie de formulations différentes, d'environ 1m2 de surface et des triplets de BTC maçonnés avec du mortier de terre sont testés en compression simple. Une différence de 38% au maximum des résistances en compression entre ces 2 types d'échantillons a été observée. Par ailleurs, l'application de la formule de l'Eurocode 6 (EC6) relative aux maçonneries conventionnelles conduit, d'une manière générale, à la sous estimation de la résistance en compression des maçonneries BTC par rapport aux valeurs expérimentales. Les rapports entre la résistance à la rupture calculée par la formule EC6 et la valeur expérimentale varient entre 44 et 72%Compressed earth blocks (CEB) masonry make it possible to build individual houses at a low environmental (and economic for poor countries) cost because of the use of local materials. Moreover, this step has a positive social and economic impact since it supports the direct human work of construction, contrary to the current type of construction based on the industrialization of the material production. Architecture used in CEB construction is adapted to a material which should support only compression stress. This thesis is a contribution to the formalization of CEB masonries buildings design which concerns, until now, only the code of practice. Only masonry behaviour under vertical compression load is analysed. As a preliminary, the CEB which constitute the principal component of masonry were studied. The various compression tests used for CEB were presented and criticized. Compression test on two half built blocks remains relevant. It was shown that three points bending test can also give compressive strength of CEB. The second component of masonry is earth mortar stabilized with cement. There exists very little information on these mortars with strong clay content (between 5 and 20 % and more). An overview of mortar tests able to be used for earth mortar is made and lead to some propositions for future studies. Finally, two types masonry samples were tested under vertical compression load ; 1m2 masonry and three blocks bpnded samples. The Euroeode 6 formula for masonry compressive strength assessment is used and the results compared with our. Experimental data

Bakgrund: Barnvaccinationsstatistiken i Sverige är hög och endast ett fåtal föräldrar väljer att inte följa det svenska vaccinationsprogrammet. Tidigare forskning visar dock att föräldrar kan ha frågor och åsikter om vaccinets innehåll och verkan. Utifrån BVC- sköterskans erfarenhet av föräldrars frågor och åsikter i samband med vaccination av sina barn på BVC kan BVC-sköterskan genom denna studie bli bättre förberedd på att möta föräldrar. Detta torde kunna bidra till att skapa ytterligare trygghet kring vaccination av deras barn. Syfte: Syftet med studien var att undersöka BVC-sköterskans erfarenhet av föräldrars frågor och åsikter i samband med vaccination av sina barn på BVC. Metod: Studien har en kvalitativ induktiv ansats. Fjorton semistruktirerade intervjuer genomfördes med BVC-sköterskor som arbetat på BVC mellan ett till 37 år. Datamaterial analyserades med hjälp av kvalitativ innehållsanalys. Resultat: Resultatet visar att föräldrars frågor och åsikter allt mer tenderar att handla om att både hantera traditionella frågor och åsikter om smärta och biverkningar men även om en allt mer aktuell utmaning gällande informationsflödet som föräldrar möter idag. Resultatet sammanfattas i två kategorier: Frågor och åsikter om att vaccinera eller inte och Frågor och åsikter om vaccinet och dess följder. Slutsats: Föreliggande studie visar att BVC-sköterskorna har erfarenhet av att föräldrar har frågor och åsikter om vaccinationer. Studien kan tillföra betydelsefull kunskap om hur föräldrar söker information och på så vis ge förbättringsmöjligheter.Background: The statistics for child vaccinations in Sweden are high, only a few parents choose not to follow the Swedish vaccination program. However, previous studies show that parents can have questions and opinions regarding the vaccines content and effects. From the BVC nurses experience of the parent´s questions and opinions in relation to the vaccination of their child at the BVC, a BVC nurse can through this study be better equipped to meet parents. This should be able to contribute to creating additional sense of security with regards to the vaccination of the child. Goal: The aim of this study was to analyse the BVC nurses experience of a parent´s questions and opinions in relation to the vaccination of their child at the BVC. Method: The study has a qualitative inductive approach. Fourteen semi-structured interviews were carried out with BVC nurses that have worked at a BVC for a duration of one to 37 years. The data material was analysed with the help of qualitative content analysis. Result: The result shows that a parent´s questions and opinions more than ever tend to revolve around both handling traditional questions regarding pain and side effects and an ever more trending challenge as the high information stream that parents meet today. The result is summarised in two categories; Questions and opinions regarding whether to vaccinate or not and Questions and opinions regarding the vaccine and its consequences. Conclusion: Previous studies show that BVC nurses have experience with regards to the parents that have questions and opinions about vaccines.
