Testo completoMale nurses are but a small percentage of the total nurse population in the United States, and most certainly have potential to increase in numbers if the profession appeared more attractive as a career option for men. The purpose of this research was to discover the decision factors used by males that led them to enroll in Associate Degree nursing programs in Illinois community colleges. To set the background and context, the study explored the history of community colleges and that of nursing. Included was nursing as a profession, nursing in the United States, the country’s impending nursing shortage and the role of men in nursing.
Using a qualitative case study method of design, the study adapted a multi-theoretical framework encompassing gender theory (GT) and career developmental theory (CDT). These theories were further broken down by discussing, in particular, Holland’s Theory (HT) of Personality and Vocational Choice and Krumboltz’s Social Learning Theory (KSLT) under CDT. Nine first year male ADN students from three separate Illinois community colleges were individually interviewed. Findings discovered that the first year male students experienced a distinctive decision making process with eight emerging themes revealing the males’ decision making about their ADN enrollment process.
As a result of the study’s findings, MURSE: Resurreccion’s Male Nursing Student Decision Making Pyramid model was developed to elaborate the steps of how males make decisions about their ADN enrollment. An understanding of these factors can provide opportunities for community colleges, and perhaps universities, to improve recruitment and retention of males in nursing programs. A result would be increased numbers of males enrolling in Associate as well as Baccalaureate nursing programs. Such knowledge held by colleges may help to address a manpower solution to the impending worldwide nursing shortage.

Testo completoThe majority of studies have demonstrated a right hemisphere (RH) advantage for the perception of emotions. Other studies have found that the involvement of each hemisphere is valence specific, with the RH better at perceiving negative emotions and the LH better at perceiving positive emotions [Reuter-Lorenz, P., & Davidson, R.J. (1981) Differential contributions of the 2 cerebral hemispheres to the perception of happy and sad faces.Neuropsychologia, 19, 609¿613]. To account for valence laterality effects in emotion perception we propose an `expectancy¿ hypothesis which suggests that valence effects are obtained when the top-down expectancy to perceive an emotion outweighs the strength of bottom-up perceptual information enabling the discrimination of an emotion. A dichotic listening task was used to examine alternative explanations of valence effects in emotion perception. Emotional sentences (spoken in a happy or sad tone of voice), and morphed-happy and morphed-sad sentences (which blended a neutral version of the sentence with the pitch of the emotion sentence) were paired with neutral versions of each sentence and presented dichotically. A control condition was also used, consisting of two identical neutral sentences presented dichotically, with one channel arriving before the other by 7 ms. In support of the RH hypothesis there was a left ear advantage for the perception of sad and happy emotional sentences. However, morphed sentences showed no ear advantage, suggesting that the RH is specialised for the perception of genuine emotions and that a laterality effect may be a useful tool for the detection of fake emotion. Finally, for the control condition we obtained an interaction between the expected emotion and the effect of ear lead. Participants tended to select the ear that received the sentence first, when they expected a `sad¿ sentence, but not when they expected a `happy¿ sentence. The results are discussed in relation to the different theoretical explanations of valence laterality effects in emotion perception.
Alderslade, Villene. "The correlation between passive and dynamic rotation in both the lead and trail hips of healthy young adult male golfers during a golf swing". Thesis, Stellenbosch : Stellenbosch University, 2014. http://hdl.handle.net/10019.1/86370.
Testo completoENGLISH ABSTRACT: Introduction-The golf swing is a complex, sequenced movement of body segments. This movement is smooth and well timed and is referred to as the kinematic golf sequence. This kinematic sequence illustrates the rotational speed, which occurs between the upper and lower body segments. Hip rotation plays an integral part to a sound kinematic sequence by providing a pivotal point between the upper and lower body segments, ensuring a synchronised golf swing. Hip rotation kinematics during a golf swing has received relatively little attention compared to other body segments’ movements. However, clinicians need to have a clear understanding of the rotational contribution that each hip make during golf swing in order to enhance the athlete’s performance and reduce the risk of injury. The aim of this descriptive research project was to obtain and investigate the total passive and total dynamic rotation range of movement in both the lead and trail hips of healthy, young adult, male golfers. Methodology-Seven, low handicapped, male golfers between the ages of 18 and 40 years were randomly selected in the Western Cape region from areas surrounding Stellenbosch University’s Tygerberg campus. A questionnaire gathered participant demographics that determined participatory eligibility. A preliminary reliability study established a baseline measurement for passive total articular hip rotation. Seatadjusted total passive hip rotation ranges of motion (ROM) measurements were collected with a hand-held inclinometer. Dynamic total hip rotation kinematic data was captured during a golf swing with an 8-camera video analysis system (VICON). Data analyses were performed with Statistica version 10. Hand-held inclinometer intra-rater reliability was determined with a two-way interclass correlation, standard error of measurement and a 95% confidence interval level. A Spearman correlation coefficient determined correlation between the total passive and total dynamic rotation range of movement in both the lead and trail hips. Results-Passive intra-rater reliability was reported as 0.81 (95% CI: 0.46-0.96). The total average passive articular range between the lead (62.1° ±6.4°) and trail hip (61.4° ±3.8°) did not report any significant difference (p=0.8). The total average dynamic golf swing articular range between the lead (29° ± 6.5°) and trail hip (35.° ±7.8°), was reported as significantly (p=0.04) asymmetric. The findings also demonstrated a positive correlation between the passive and dynamic total articular range in a lead hip, whereas a negative correlation was reported in a trail hip. During the golf swing the lead hip utilised 46.4%(± 8) of the total passive available hip rotation, whereas the trail hip utilised 58.8% (±13.2). Discussion and Conclusions-The findings of this study show that, the passive rotation ROM in a hip (LH=62°; TH=61°) of a golf player does not exceed the available range it has during a golf swing. The golfer’s hip utilises 46% of the available passive range of movement in the lead hip and 59% in the trail hip. In the clinical field careful consideration should be given to the motivation behind mobilizing, treating or stretching the hips of a golf player. These findings can be incorporated in future research on the relationship between hip-rotation ROM and reduction in the incidence of injuries amongst golfers.
AFRIKAANSE OPSOMMING: Inleiding-Die gholfswaai is n komplekse, opeenvolgende beweging van verskeie liggaamsegmente. Hierdie gladde opeenvolgende bewegings word die kinematiese gholfpatron genoem. Hierdie kinematiese opeenvolgende bewegings bied ’n illustrastrasie van die rotasiespoed waarteen die beweging tussen die boonste en onderste liggaamsegmente plaasvind. Heuprotasie speel ’n deurslaggewende rol in hierdie glad verlopende kinematiese proses. Dit dien as ’n spilpunt tussend die boonste en onderste kwadrant, wat op sy beurt weer ’n gesinkroniseerde gholfswaai verseker. Die heuprotasie kinamtieka tydens n gholfswaai het relatief minder aandag ontvang in vergelyking met ander liggaamsegmente. Klinici moet instaat gestel word om ’n duidelike begrip aangaande die bydrae wat heuprotasie tydens ’n golfswaai lewer, te ontwikkel. Die atleet se prestasie kan sodoende verbeter word, en die risiko tot beserings kan ook sodoende voorkom word. Die doel van hierdie beskrywende navorsingsprojek was om te bepaal wat die totale passiewe en die totale dinamies rotasie omvang van die leidende en volgende heupe van gesonde jong mans wat gholf speel, te ondersoek. Metodologie-Sewe gholf-geskoolde manlike gholf spelers met ’n lae voorgee en tussen die ouderdom van 18 en 40 jaar is ewekansig gekies. Hierdie kandidate is gekies uit die omliggende gebiede van die Stellenbosch Tygerberg kampus in die Wes-Kaap waar hulle relatief naby woonagtig was. ’n Vraelys is aangewend om demografiese eienskappe van elke deelnemer in te samel. Hierdie inligting wat deur die vraelys bekom is, is gebruik om te bepaal of die deelnemers in aanmerking is vir die studie. ’n Voorlopige, intra-meter betroubaarheidstudie is gedoen vir passiewe, totale artikulêre heuprotasiemetings wat met ’n hand hanteerbare hoek meter geneem is. ’n Algemene fisiese ondersoek is in die biomeganiese labaratorium afgehandel om te bepaal of die deelnemers geskik is vir die toetse. Sit-aangepaste passiewe totale hip rotasie beweging metings was ingesamel met 'n hand hanteerbare hoek meter. Intra-meter betroubaarheid is bepaal met ’n twee-rigting interklas korrelasie, standaard foutmeting en ’n 95% vertroue interval vlak. Dinamiese totale heup kinematiese rotasiedata is afgeneem met ’n hoë-spoed 3-D videografiestelsel (VICON) tydens 'n gholfswaai. Data-ontleding is bereken met ’n Statistica weergawe 10. Die gemiddelde en Spearman korrelasie koëffisiënt is gebruik as aanwysers van verspreiding. Resultate-Passiewe inter-meter betroubaarheid word geraporteer as 0.81 (95% KI: 0.46-0.96). Die resultate dui op ’n onbeduidende totale passiewe artikulêre reeks verskille tussen die leidende (voorste) (62.1 ± 6.4 °) en volgende (agterste) heupe (61.4 ° ± 3.8 °). ’n Beduidende totale dinamiese artikulêre reeks van die leidende (29 ° ± 6.5 °) en volgende heupe (35.9 ° ± 7.8 °) is tydens die gholfswaai bereik. Verdere resultate toon ’n positiewe korrelasie tussen die passiewe en dinamiese totale artikulêre reeks in die leidende heup, terwyl ’n negatiewe korrelasie gerapporteer word vir die volgende (agterste) heup. Tydens ’n gholfswaai gebruik die leidende heup 46.4% (± 8%) van die totale passiewe beskikbaar heuprotasie, terwyl die opvolgende (agterste) heup 58.8% (± 13.2%) aanwend. Bespreking en gevolgtrekking-Die bevindinge van hierdie studie toon dat tydens ’n gholfswaai, ’n gesonde gholfspeler nie die beskikbare passiewe beweging wat in sy heup bestaan oorskry nie. Slegs 46.4% van die beskikbare passiewe beweging in sy leidende heup word gebruik, en 58.8% van sy agterste heup. Die klinisie moet deeglike oorweging gegee word aan die motivering agter die mobilisering, strekke en die behandeling van die heupe van ’n gholfspeler. Hierdie bevindings kan in toekomstige navorsing geimplimenteer word om die verhouding wat tussen die omvange vand heuprotasie bestaan te ondersoek. Die voorkoming van moontlike toekomstige beserings in gholfspelers kan ook verhoed word.

Devesa, Joana Moura. "Treatment of a nineteenth century male portrait in oil including the characterisation of materials, technique and a study of the lead soap aggregation in the paint composite". Master's thesis, Faculdade de Ciências e Tecnologia, 2012. http://hdl.handle.net/10362/9754.
Testo completoThis project involved the conservation of a 19th century portrait in oils from the Ecomuseu do Seixal (Portugal). The painting of “João Luiz Lourenço” was in very poor condition. Because of the range and severity of the problems presented, it offered an opportunity to explore important aspects of painting conservation in-depth. The approach to its treatment required an empirical investigation of a number of materials and techniques used in the field of conservation/restoration. Of additional interest, the painting exhibits widespread evidence of metal soap (lead carboxylate) aggregates protruding through the paint from the ground layer. The painting’s materials and the metal soaps aggregates were studied and characterised with different analytical techniques: μ-EDXRF (Energy Dispersive X-ray Fluorescence), μ-Raman Spectroscopy, μ-FTIR (Fourier Transform Infrared Spectroscopy) and SEM-EDX (Electron Scanning Microscopy with Energy Dispersive X-ray Spectroscopy). Part 1: describes the study of the materials and the technique of the painting, and of the metal-soap aggregation within the painting’s ground layer. Observation with the Optical Microscope and with SEM-EDX of paint/ground cross-sections reveals the presence of two visually distinct lead carboxylate aggregates: one, completely white, and the other with a white centre surrounded by distinct red particles identified as red lead (minium: Pb3O4) by μ-Raman. The presence of these two types raises questions about whether there are different starting materials for the aggregates or whether they could be in different states of evolution. Part 2: describes the design and implementation of the conservation/restoration treatment. The treatment of the painting raised challenges and at various stages involved the exploration of non-traditional methods. At every stage during the treatment the consequences of an intervention was carefully considered in relation to the subsequent steps. All decisions were taken according to the painting’s intrinsic conservation problems and materials and with regard to the future environment of the painting.

Testo completoPretende-se com este trabalho, desenvolvido em ambiente industrial, avaliar a implementação do projecto ‘Lean’ na Bi-Silque. Esta é uma análise crítica de algumas dessas acções, levadas a cabo com o apoio de uma empresa de consultoria e também avaliar até que ponto essas acções se coadunam com o tipo de empresa em questão. Durante o tempo de estágio na empresa, o envolvimento pessoal em várias dessas acções, permitiu olhar de uma forma geral para o processo produtivo dos vários sectores da fábrica, podendo formar uma opinião baseada na experiência obtida, mas também fundamentada em bibliografia sobre o tema. Não se tratando esta, de uma típica empresa “make-to-order” ou “make-tostock”, a implementação de acções “Lean”, deve ter em consideração as “nuances” da realidade desta empresa. As acções devem ser orientadas para a agilização do processo produtivo e não se fixando apenas em partes dele, já que este procedimento acaba por não surtir os efeitos desejados, como se irá ver na análise dos dados recolhidos. Para poder justificar a análise feita, além da bibliografia sobre o tema, foram recolhidos indicadores, quer sobre produtividade e rupturas de artigos nas linhas de produção, como também o cumprimento de prazos por parte da empresa para com os seus clientes. Por fim, através da experiência do dia-a-dia da fábrica, este trabalho culmina com algumas sugestões de melhoria de funcionamento organizacional, ao nível da produção, relação interdepartamental, clientes e fornecedores.
The aim of this study, developed in an industrial environment, was to evaluate the implementation of 'Lean' project in Bi-silque. This is a critical analysis of some of the actions carried out, with the support of a consulting firm, to assess the extent to which those actions were consistent with the type of company in question. During the trainee, the personal involvement in several of those actions, allowed me to look in a general way to the production process of the various sectors of the factory, allowing me to form an opinion based on that experience, but also based on literature on the subject. Since it is not this, a typical company "make-to-order" or "make-to-stock", the implementation of actions "Lean", should take into account the "nuances" of the reality of this company. Actions should be geared towards streamlining the production process and not just settling parts of it, since this procedure turns out not have the desired effect, as you will see in the analysis of the data collected. To justify the analysis, in addition to literature on the subject, indicators (KPI’s) were collected either on productivity and disruptions of articles on the production lines, as well as meeting deadlines for the company towards its customers. Finally, through the experience of day-to-day factory, this paper ends with some suggestions for improving organizational functioning, the level of production, interdepartmental relations, customers and suppliers.

Value Stream Mapping of the Singapore operations of a multi-national food products packaging company was carried out with the objective of streamlining production in accordance with the World Class Manufacturing philosophy. An opportunity for reduction in WIP and lead time was identified. Simulation models were used, on the make- to-order, serial production system to test three potential solutions to the problem. The models used showed great promise for reduction in WIP and the lead time for both the priority and ordinary products. The role of design as a sorting criterion on the printer was also investigated by a fundamental integer programming model using the Travelling Salesman approach. Results confirming the significance of design in the printer setup process were obtained in the trial run.

A high-mix, make-to-order production system can become inefficient when non-value added operations consume too much time, space or labour. To address these issues, cell re-layout is conducted and a CONWIP system is proposed. The cell re-layout started with data collection on current layout, product mix and routings, then the current layout was modified to develop several alternatives, and finally the best alternative was selected based on a set of criteria. The Pull system design began with comparison between Kanban and CONWIP with respect to an actual production system, and then the CONWIP system was selected and a sample case study based on ARENA 12.0 was included to study the characteristics of CONWIP. Finally, transformation of the actual production system to CONWIP was studied in ARENA simulation to determine its optimal CONWIP setting. It can be concluded that the cell layout resulted in improved operator efficiency and savings in area occupied, while the CONWIP system leads to reduction in amount of work-in-process, and stabilization of manufacturing lead time.

"Health effects of endocrine disruptors during pregnancy and childhood Exposure to heavy metals during pregnancy related to gestational diabetes mellitus in diabetes-free mothers Prenatal exposure to phthalates and the development of eczema phenotypes in male children: Results from the EDEN mother-child Cohort study". Thesis, Sorbonne université, 2019. https://accesdistant.sorbonne-universite.fr/login?url=http://theses-intra.upmc.fr/modules/resources/download/theses/2019SORUS243.pdf.
Testo completoAll humans are exposed to chemicals in everyday life, from food, indoor environment, cosmetics and other products that surround us at home and at work. Endocrine disruptors (EDCs) are man-made compounds that can bind to cell receptors and mimic or block the functions of natural hormones potentially resulting in adverse health effects. In recent years, hypotheses have been put forward that EDCs may contribute also to the development of allergic and respiratory diseases. In addition, it is likely that EDCs could act already during pregnancy by causing gestational diabetes mellitus and pregnancy induced hypertension, which may also trigger to develop hypertension and diabetes mellitus later in life. This dissertation provides evidence that maternal exposure to phthalates and heavy metals (Lead, Cadmium and Manganese) during pregnancy may be associated with gestational diabetes mellitus, pregnancy induced hypertension and later eczema/atopic dermatitis in children. We used ongoing French EDEN-mother child cohort data for our three studies. Our results add new suggestive evidence on the relationship between EDCs (phthalates and heavy metals we studied) and maternal and children health, that prenatal exposure to certain phthalates and heavy toxic metals may play a role in the development of gestational diabetes mellitus and pregnancy induced hypertension during pregnancy and later eczema in early childhood. Future research focusing on larger populations and addressing multiple exposures assessed prenatally and postnatally are required to provide more evidence on possible contributions of emerging pollutants to study the role of phthalates and heavy metals

"Sänka bundet kapital i ett mellanlager : -En studie utförd i syfte att finna orsaken till varför lager bildas för att därefter presentera en eller flera åtgärder som bidrar till minskat bundet kapital i lager". Thesis, Tekniska Högskolan, Högskolan i Jönköping, JTH, Industriell organisation och produktion, 2018. http://urn.kb.se/resolve?urn=urn:nbn:se:hj:diva-41535.
Testo completoSyfte – Globaliseringen har gjort att kunden har ett högre utbud att välja mellan och kan därmed ställa högre krav på tillverkande verksamheter. För att fortsatt vara konkurrenskraftig måste verksamheter ständigt utveckla den interna produktion- och materialstyrningen. Studiens ämnar därmed undersöka orsaken till uppkomsten av bundet kapital i lager samt finna potentiella åtgärder som kan vidtas inom verksamheten för att på ett hållbart sätt minska bundet kapital i lager. Metod – För att uppfylla studiens syfte tillämpas fallstudie. Studien utgår från två frågeställningar som besvaras med hjälp av data från ett fallföretag. Data som samlas är hämtad från sekundärdata, observationer och intervjuer. Därtill har ett teoretiskt ramverk upprättats vilken studien utgår ifrån. Resultat – Minska variationer samt utförande av en mer detaljerad planering presenteras som studiens två åtgärdsförslag för att minska bundet kapital i lager. Studien beskriver övergripande potentiella tillvägagångssätt för att åstadkomma förslagen. Studien konstaterar att flödeseffektivitet med fördel bör prioriteras framför resurseffektiviteten i verksamheten, vilket uppfylls med hjälp av åtgärdsförslagen. Implikationer – Studien bidrar inte till nya teorier men verifierar befintliga teorier främst kring variationer i tillverkning, Lean och ledtidskartläggning. Begränsningar – För att åtgärdsförslagen i studiens resultat ska kunna tillämpas krävs ytterligare data och fördjupade studier för att garantera att samtliga aspekter ska fångas in samt att orsak och påverkan av åtgärderna ska kunna kartläggas. Studien bygger på generaliserande antaganden vilket ger ett generaliserat resultat. Nyckelord – Lean, Ledtid, Ledtidskartläggning, Variationer, Flödeseffektivitet, Senareläggning, Just-in-Time, Make-to-order och Bundet kapital.

Testo completoFöretag som jobbar enligt tillverkning-mot-order och utveckling-mot-order har ofta få standardprodukter och en efterfragan som är svår att forutsäga. För att fåbeställningar skickar företaget offerter och konkurrerar om kunderna. Uppsatsen syftar till att identiera de faktorer som bidrar till osäkerhet i ledtiden hos tillverkning-mot-order-företag och sedan föreslå en metod för att hantera eller eliminera några av dessa faktorer. En fallstudie genomfördes på ett medelstort finmekanikföretag som kombinerar tillverkning-mot-order och utveckling-mot-order i ett manuellt produktionssystem. Företaget har långa ledtider i både orderprocessen och monteringen. Ledtiderna hos företaget mäts i veckor snarare än minuter, timmar eller dagar. Information samlades in under en tremånadersperiod genom intervjuer med de anställda, närvaro på möten och observationer av monteringen. Informationen strukturerades och analyserades med hjälp av till exempel släktskapsdiagram, relationsdiagram och en miniriskanalys. En lösning valdes genom ett matrisdiagram, som jämför olika möjliga lösningar i förhållande till de identifierade faktorerna. Undersökningen visade att offereringen av leveranstider var ett betydande problem. Det finns en tendens att offerera mer än vad som skulle vara möjligt att producera, för att se till att företaget får tillräckligt med beställningar. Denna strategi orsakar osäkerhet i de ledtider som offereras, eftersom fler offerter än vad som är mojligt kan accepteras och beställningar får sedan vänta på att andra ska bli klara. De långa ledtiderna ökar problemet ytterligare, eftersom effekterna från offertfasen inte märks förrän månader senare. Många gånger resulterar det i att företaget har allt för många beställningar att jobba med och en stressig miljö i monteringen. De föreslagna förbättringarna bygger på arbetsbelastningskontroll, med beslutspunkter vid kundförfrågan & beställning samt orderstart i montering. Målet är att företaget ska kunna göra väl underbyggda och motiverade planeringsbeslut där prioriteringar tillämpas på ett systematiskt sätt. Fokus bör därför ligga på att förbättra kommunikationen mellan avdelningarna. Ett viktigt steg är att visualisera kapacitetsutnyttjandet när vi letar efter ett nytt leveransdatum. Även de offerter som skickats ut men ännu inte accepterats bör beaktas eftersom de innebär en eventuell efterfrågan och användning av kapaciteten. Det förväntade resultatet av metoden är att de offererade ledtiderna kommer att vara mer exakt och bolaget kommer att ha bättre möjligheter att leverera i tid.

Testo completoRoutinely recognized as deeply patriarchal, early modern England is an era in which men and characteristics of the male gender are assumed to have held unrelenting sway over their female counterparts. This description is largely justifiable, particularly given the era's legal codes. However, this thesis seeks to enrich discussions on early modern England by examining its male-female relationships through a markedly different lens. By highlighting the close relationships that existed alongside patriarchal mandates in the era - husband and wife, father and daughter, mother and son - a fuller portrait of the period is sketched. Through an examination of how a variety of genres - medical, religious, and dramatic - grappled with moments of union between the two sexes, particularly physical union and its concurrent or resultant emotional bonds, this thesis offers greater insight into how walls to male-female connection were both raised and bridged in the time period

Testo completoIl genere Cichorium (Cichorium intybus subsp. intybus var. foliosum L.) comprende specie vegetali diploidi (2n=18) appartenenti alla famiglia delle Asteraceae. Queste specie sono generalmente biennali o, in natura, perenni. Si tratta di specie prevalentemente allogame a causa di un efficiente sistema di autoincompatibilità sporofitica. Inoltre, la fecondazione incrociata è favorita da una morfologia fiorale sfavorevole all’autofecondazione, se in assenza di un impollinante (ad esempio la proterandria, ovvero la presenza di antere mature prima dei pistilli). In specie di questo genere si riscontra, inoltre, una forte competizione gametofitica, ovvero il rigetto di polline geneticamente simile a quello prodotto dal parentale femminile. A lungo apprezzate come piante medicinali dagli antichi Greci e Romani, le specie del genere Cichorium sono attualmente tra le più importanti specie orticole coltivate. Sono generalmente utilizzate nella preparazione di insalate fresche o, più raramente, cucinate secondo le tradizioni alimentari locali. Anche se la coltivazione della cicoria non contribuisce largamente all’introito agricolo totale di ogni paese, questa risulta essere molto importante a livello locale, in quanto caratterizza l’agricoltura di aree limitate dove è concentrata la coltivazione dell’80-90% della produzione nazionale di questa coltura. Questo è in effetti il caso dell’Italia dove, il 66% dell’ettarato e il 59% della produzione nazionale di una cicoria da foglia rossa o variegata conosciuta come “Radicchio” è concentrata in Veneto. La produzione di Radicchio è stata per un lungo periodo basata su popolazioni mantenute dagli agricoltori, che venivano di anno in anno selezionate e il cui seme veniva solitamente riutilizzato all’interno del centro aziendale o poteva venir venduto attraverso transazioni private e solitamente non ufficiali. Tutte queste popolazioni, ottenute per selezione massale e mantenute attraverso l’interincrocio di parentali selezionati, devono essere considerate altamente eterozigoti e geneticamente eterogenee; il comportamento e il livello di adattamento di queste popolazioni ai diversi ambienti e condizioni agronomiche, è funzione della frequenza di geni favorevoli e della loro combinazione. In ogni programma di miglioramento genetico, gli schemi e i metodi di selezione che possono essere adottati e le tipologie varietali che possono venir costituite, dipendono dalle barriere riproduttive delle piante (come l’autoincompatibilità), dai sistemi di impollinazione (ad esempio l’allogamia) così come dalla struttura genetica delle popolazioni. La forte autoincompatibilità rinvenuta in cicoria, rende estremamente difficile l’ottenimento di parentali altamente omozigoti nell’ottica di un efficiente schema di ottenimento di ibridi F1. Nonostante le difficoltà incontrate nell’ottenimento di linee inbred attraverso cicli ripetuti di autofecondazione, la recente scoperta di mutanti maschiosterili spontanei ha aumentato l’interesse verso la produzione di varietà ibride F1. La maschiosterilità, o l’incapacità delle piante di produrre polline funzionale, è utile per la produzione di seme ibrido commerciale, attraverso l’incrocio di linee inbred parentali appropriatamente selezionate attraverso test di progenie, per stabilire l’attitudine alla combinazione specifica. In questo progetto abbiamo sviluppato un metodo di genotipizzazione utilizzando marcatori molecolari, utile per stabilire il grado di omozigosi e la stabilità genetica di singole linee inbred e per la misurazione dell’attitudine alla combinazione specifica tra linee portaseme ed impollinante sulla base della loro diversità genetica. Queste informazioni possono essere utilizzate per programmare incroci e predire l’eterosi di ibridi F1 sperimentali sulla base della distanza genetica della linee parentali. Conoscendo il genotipo dei parentali, saremo in grado non solo di proteggere ogni nuova varietà rilasciata sul mercato ma anche di stabilire il grado di purezza e identità varietale del seme ibrido commerciale e di certificare l’origine dei suoi derivati alimentari. La costituzione di varietà ibride F1 vigorose e stabili si avvarrà del breeding moderno assistito da marcatori utilizzando tecnologie quali marcatori SSR e SNP, senza alcun collegamento con tecniche di l’ingegneria genetica, combinando tratti di qualità, uniformità e produttività all’interno degli stessi genotipi. Inoltre, nell’ambito di questo progetto di ricerca abbiamo trattato la scoperta e la caratterizzazione genetica di quattro mutanti maschiosterili in questa specie. Questi mutanti, che da quanto ci risulta dalle informazioni in nostro possesso sono i primi mutanti maschiosterili spontanei mai scoperti e descritti in Radicchio, sono stati dettagliatamente caratterizzati per la via metabolica dello sviluppo della microsporogenesi e gametogenesi e per il modello di ereditarietà del gene responsabile della maschiosterilità. Abbiamo sviluppato un saggio diagnostico basato su marcatori molecolari per la selezione precoce di genotipi associati a piante maschiosterili. In questo modo si è dimostrato che i mutanti maschiosterili oggetto di questo progetto di ricerca sono controllati da un singolo gene nucleare (ms1) che agisce allo stato recessivo. Siamo stati in grado di mappare il gene responsabile della maschiosterilità in una regione cromosomica satura e ben caratterizzata di circa 7.3 cM e 5.8 cM dal locus ms1. Complessivamente queste informazioni saranno fondamentali per la pianificazione di un esperimento di Genotyping-by-Sequencing basato su una popolazione BC1 con l’obiettivo di restringere la finestra genomica contenente il gene responsabile della maschiosterilità in cicoria da foglia. Infine il sequenziamento e l’assemblaggio della prima bozza del genoma di cicoria da foglia discussi in questo studio, contribuiranno ad aumentare e rafforzare la credibilità delle ditte sementiere italiane e delle attività locali in Veneto correlate alla coltivazione e la commercializzazione del Radicchio e prodotti alimentari connessi; il mercato sementiero di questa specie avrà la possibilità di diventare altamente professionale e fortemente competitivo a livello nazionale ed internazionale. Abbiamo assemblato una bozza del genoma della misura stimata di 760 Mb. Abbiamo ottenuto 58.392.530 e 389.385.400 sequenze grezze rispettivamente attraverso le piattaforme di sequenziamento MySeq e HiSeq. Abbiamo identificato complessivamente 66.785 regioni contenenti motivi SSR. Abbiamo riportato i dati bioinformatici di assemblaggio della prima bozza del genoma di Radicchio, insieme ai dati più salienti provenienti da una predizione genica de novo e da una annotazione funzionale in silico di più di 18.000 unigenes. La scoperta del genoma di Radicchio significa l’ottenimento di una base scientifica solida e una conoscenza tecnologica tale da giocare in breve tempo un ruolo cruciale nella risoluzione di problematiche legate alla protezione e la coltivazione di moderne varietà di Radicchio. Siamo fiduciosi che i nostri sforzi amplieranno l’attuale conoscenza dell’organizzazione del genoma e della composizione genica della cicoria da foglia, che si ritengono essere fondamentali nello sviluppo di nuovi strumenti e saggi diagnostici basati su marcatori molecolari utili alle strategie di costituzione varietale e che permettano studi più specifici di tratti cromosomici che controllino aspetti agronomici rilevanti in questa specie. In conclusione, il presente lavoro è da leggersi come una sorta di manuale per meglio capire il mondo di una specie non modello come la cicoria da foglia, orientato prevalentemente verso i costitutori genetici e i produttori di sementi di cicoria.

Significant growth in the sales is expected in the coming years for the product family that is the focus of this research. In order to meet the takt time for the future demand, improvement on the current processes and expansion are needed. In this work, Value Stream Mapping was implemented to identify the bottleneck processes: fit up (oval), full welding, and pressure testing. Assembly cell concept, workload balancing and FIFO lanes were proposed countermeasures or improvements to address the capacity shortfall. A decrease of 27% in manufacturing lead time was projected if these improvements were made. In addition, the capacity analysis suggests that an expansion is required in full welding and heat treatment furnace.

Testo completoThe printing sector in Peru constantly faces the need to reduce production time because late deliveries to the customer owing to high manufacturing time are critical problems. Previous studies have proposed using the lean manufacturing philosophy to reduce idle times by improving the flow of information within the production processes in large manufacturing companies but not printing SMEs using these tools in a make-to-order environment. This document focuses on implementing an affordable lean manufacturing model in an SME company with a make-to-order environment to reduce its manufacturing times. Therefore, the Kanban, Single Minute Exchange of Dies (SMED), and value stream mapping (VSM) processes will be adapted for implementation in these companies. Then, the model is validated through its application in a case study; through process simulation, production times were reduced by 24% for an SME, delivering all orders on time, and eliminating 100% penalty costs for late orders.

Testo completoIn Sweden and other countries in the world, it’s common that you build green certified buildings. There’s a great demand for Green buildings and there are different kinds of green building certification systems that can be used in both new construction and repair jobs. Efficiency and energy issues surrounding the building are topics that green building certifications treat, because it is common that these issues and improvements also is applied to existing buildings in order to reach an green building classification. LEED is an American classification system that is one of the most known systems in the world and it’s also used in Sweden. In order to use LEED while constructing a building it puts a pressure on the planning group and even for the people in construction. To make everything work according to the LEED requirements, it will be extra important that everyone within the building process should have knowledge of what is required from each person involved in the construction. How should the knowledge increase and construction efficiency improve? We propose it can be done by using a template which is also called "Mallen". This will be available for all involved in the production process and will result in an increased knowledge about LEED within the company. By that the efficiency of the work increases. When both knowledge and efficiency have increased and shown good results it should then also reduce the costs.

Women in technology have always been a minority and the number of women who are founders of venture backed start-ups is even lower. This research empirically investigates venture capital funding received by entrepreneurs along the twin dimensions of gender and geography. The ideal experiment would have been to study the numbers of entrepreneurs who pitch their ideas to venture capitalists by gender, and correlate that number with attrition rates during each stage, and finally study the funding outcome, fully accounting for survivor bias. This data could not be accessed. Therefore, we decided to use the financial crisis of 2008 which resulted in illiquid capital markets as a proxy, and studied pre- and post-crisis funding outcomes. The study assumes Q3'08 as date of crisis. The results indicate that gender does not affect the chances of receiving follow-on funding. The key factors that affected funding were the participation of reputed investors in the pre-crisis funding event, and geographic location of the venture. Men founders were more likely to receive follow-on funding in Massachusetts compared to women founders, while women had a significantly better chance of receiving funding in California compared to their male counterparts. We then investigated the cause of the surprising results. Our analysis indicated that the majority of the women founders who received pre-crisis funding in California were either experienced entrepreneurs with prior founding experience, or possessed an advanced technical degree (Ph.D.). This was in sharp contrast to the women who founded technology companies in Massachusetts who were mostly first time founders, and the majority did not possess advanced technical degrees.

Testo completoThe purpose of this paper is to provide a proposal of a production management model using lean manufacturing techniques to improve on-time deliveries of a metal-mechanic company that works in a make-to-order (MTO) manufacture of industrial fans environment. The proposal of the research refers to the implementation of a production management model in a metal mechanic company in Peru and analyze the effect in on-time delivery rate of the company. In one month of operation after the implementation of the pro-posed model, the on-time delivery rate of the company increased from 35% to 80%. Likewise, the problems present in the metalworking research company may be the same in many metalworking companies in the country, so the present investigation will serve as an example for the possible solution of the problems of other companies.

Testo completoMossberg (1998) confirms that batch-based logistics in the book industry has several negative consequences. Mossberg (1998) writes the following; "AN ONGOING WASTE OF RESOURCES The unsold books are incurring transportation and inventory costs ... ... surplus - often more than half the recipients edition! -- canceled within three years. Aside from the offensive in this waste of resources, this procedure contributes to the fact that the Swedish book market has got the '' fresh character '' as mentioned earlier -- and as entails a temporal limitation of the Swedish-language literature" (Mossberg, 1998) Mossberg's (1998) findings also support the observations we have made in this study. This constitutes the foundation of this survey, where we contributes for a more effective and sustainable operation at one of Sweden's largest economy book producers. The purpose of this study is to examine the advantages and disadvantages that come with make-to-stock and a batch based logistics management of books. But also to identify the advantages that, according to the theory, can be achieved in a transition to make-to-order with a print-on-demand solution. The goal is to present recommendations for decision-making and future strategy for the company where this study took place, as well as to help other companies with similar needs and requirements. This case study is conducted at a Swedish company which essentially work with customer service / support to businesses using their accounting software and services. An important part of their service means publishing as well as e-books sale of information books. We have noticed that little is done to improve their efficiency and quality in this area. Our study shows that this company would gain several benefits by making use out of a print-on-demand solution. This because it would improve their quality in all respects we’ve focused on, with a lower total cost, no tied up capital and en reduced environmental impact.

Testo completoAsh-leaf maple (Acer negundo) is listed among 5 alien invasive plant species in Lithuania. Because of intense invasion to the habitats of river banks and negative influence on biodiversity, investigations on this species biological and ecological caracteristics were started in order to reveal its impact on natural environment. The aim of the work was to reveal fecundity and variation of fruit parameters in relationship with tree age and habitat characteristics. Following tasks were formulated: (1) to reveal age of fecundity of female individuals of ash-leaf maple; (2) to estimate dependence of raceme parameters upon tree age and habitat characteristics; (3) to reveal relationships of fruit morphological parameters with tree age and habitat characteristics; (4) to investigate variation of fruit parameters in and among populations.
