Full textAbstract:
The Goose at Goldie's Milk Bar is a modern literary fairy tale written in the form of a novel for adult readers. Set in the fictional Australian small country town of Baxters Creek, it tells the story of Goldie Sullivan, an elderly former milk bar proprietor who has an affair with a gigantic cognisant gander. Goldie lives out the back of the town's old milk bar, hiding from the surrounding narrow-minded community, until late one night she witnesses a bolt of lightning strike the bell tower on the nearby church. When she goes to investigate, Goldie finds the body of a large bird buried in the debris and, believing it is an omen, she carries the half-dead bird home on her back. As she rehabilitates the bird, Goldie discovers there is more to the feathered creature than she first thought. The bird, a giant gander blown off course and struck down in the middle of migration, reveals an advanced awareness of humanity and the profound ability to comprehend the sorrow in Goldie's life. Through a shared appreciation of jazz music, Goldie and the goose learn to communicate and a close friendship ensues. Goldie teaches the goose to dance, the pair share baths and the goose moves into Goldie's bedroom. Before too long, Goldie finds herself in the midst of a most indecent affair. Goldie's relationship with the gander unfolds against a backdrop of other unconventional relationships. Kevin Dwyer, the new reporter in town finds himself drawn to the shire maintenance worker, Travis Handley. Real estate agent Alexander Bourke has taken Lynne Fontaine, the chef at the local Chinese restaurant, as his oriental mistress, and recently windowed farmer, Mary Peddley, sets tongues wagging with the one-legged publican, Jack Diamond. The novel uses the human animal narrative to explore the premise that fate is driven by unseen, sometimes magical forces that manifest in inexplicable ways to reveal the hidden truths of people. The writing of the novel has been supported by research conducted for an exegesis titled, The Nature of Human Animal Relationships in Three Modern Literary Fairy Tales. The exegesis identifies and discusses the nature of the central human animal relationships in three novels: Yann Martel's Life of Pi, Peter Hoeg's Woman and the Ape and the writing project, The Goose at Goldie's Milk Bar. The exegesis identifies and discusses the roles and functions the human and animal characters perform in the three novels through a comparative analysis of the narrative theories of early Russian Structuralist, Vladimir Propp. The exegesis also identifies and discusses the types of transformation the human and animal characters undergo, and conducts a comparative analysis of the theories of English academic and fairy tale historian, Jack Zipes. Finally, the exegesis analyses and discusses the multi-dimensional nature of the bonds formed by the human and animal characters and demonstrates how writers of modern literary fairy tales seek to awaken the reader to the possibilities of relationships with animals beyond usual human understanding or experience.

DEVELOPMENT AND VALIDATION OF A LIGHT WEIGHT, ENERGY DENSE, READY TO EAT (RTE) BAR
Jacob Wilhelm-Maria Heick
Providing additional calories in the form of an RTE bar to endurance athletes will increase performance and muscle re-synthesis, reduce muscle breakdown, and shorten recovery time. An RTE bar containing a blend of dairy proteins and carbohydrates will create a product with superior functionality, including bioactive and immunity enhancing properties from dairy derived ingredients. The protein will provide benefits in the form of easily digestible calories, essential amino acids and physical satiate.
A formulation was developed and optimized, resulting in a final product that meets the required nutritional profile: 400kcal, 25grams protein per 100 gram serving size. The desired physical characteristics were achieved through processing by both conventional baking and freeze drying. The latter method improves the stability and functionality of the RTE bar.
In order to meet the protein requirements of the RTE bar without compromising sensory properties, a unique protein source was developed. Using high concentrations of conventional protein sources like Whey Protein Concentrate (WPC) resulted in stale off-flavors and unappealing textures. Milk Protein Precipitate (MPP) was developed for this formulation. MPP is a curd-like ingredient created through the combined heat and acid precipitation of dairy proteins. MPP can be used effectively in high concentrations provides a subtle dairy flavor. MPP delivers a balance of casein and whey, similar to that found in milk.
The effectiveness of the RTE bar formulation as a post exercise recovery food was evaluated in a human studies experiment conducted on the Cal Poly campus. The human subjects study utilized 34 Cal Poly students in a single-blind cross-over design experiment. The study compared the effects of this high protein RTE bar against a calorically equal carbohydrate bar. The bars were administered after subjects completed the pre-assigned hikes on three consecutive days. Following the cross-over design, subjects received the alternate bar in the second period of the experiment. Several blood markers involved in metabolism and inflammation were measured before and after the two treatment periods. No blood marker showed a statistically significant difference between bars, but several trends were observed. Body weight and fat percent were also unaffected by bar composition.

Full textAbstract:
Attention Deficit Hyperactivity Disorder (ADHD) is becoming a more common diagnosis of younger children. In recent years the perception that some ingredients in our food may have a negative effect regarding the symptoms in children with ADHD has grown stronger. Children with ADHD often suffer from irritated bowel syndromes which affect their ability to digest food. This may result in malnutrition as well as a release of substances that are harmful.The purpose of this report is to compile and illustrate the knowledge of how special food, particular milk protein and gluten, may affect the symptoms of children with ADHD. Also, the report aims to evaluate if there should be changes made in Kindergarten to increase the well-being of these children. The report is a summary of research results on the effects milk protein and gluten have on children with ADHD.The majority of children with ADHD demonstrate decreased symptoms if they receive a diet without milk protein and gluten.If children with ADHD would be given a special diet excluding milk protein and gluten it is realistic to assume that their ADHD-symptoms might be reduced with a greater sense of well-being and quality of life as a result.Attention Deficit Hyperactivity Disorder (ADHD) är en allt mer vanligt förekommande diagnos hos förskolebarn. Uppfattningen om att en anpassad kosthållning kan lindra symtomen hos barn med ADHD har växt sig starkare de senaste åren. Barn med ADHD lider ofta av en irriterad tarm som har en störd matspjälkningsfunktion, vilket kan leda till att näringsämnen bryts ner ofullständigt och resulterar i näringsbrister och frisättning av ämnen som kan påverka oss negativt.Syftet med rapporten är att sammanställa och belysa kunskapen om hur kosten kan påverka symtomen hos barn med ADHD, med särskild inriktning på påverkan från mjölkprotein och gluten. Samt att belysa vilken nytta skolverksamheten kan ha av dagens forskning inom ämnet.Rapporten är en sammanställning av de forskningsresultat som finns inom ämnet ADHD-anpassad kost där mjölkprotein och gluten utesluts.Majoriteten av barn med ADHD påvisar en minskade symtom om de får en anpassad kost utan mjölkprotein och gluten.Om förskolan skulle erbjuda barn med ADHD en anpassad kost är det realistiskt att anta att deras ADHD-symtom skulle kunna minska med ett ökat välbefinnande som följd.

Full textAbstract:
Bakgrund: Idag är det vanligt att mödrar inte ammar, dock värderas detta fortfarande lågt i samhället. Forskningen som finns angående dessa mödrars erfarenheter av anknytning till sina barn, är begränsad. En distriktssköterska ska kunna ge olika sorters stöd i moderskapet, exempelvis genom praktisk kunskap och på ett sätt som identifierar mödrars upplevelser kring att inte amma. Syfte: Syftet med denna studie var att beskriva hur mödrar som ger sina barn modersmjölksersättning, upplever känslorna och relationen till sina barn. Metod: Tio intervjuer med mödrar genomfördes. Kvalitativ innehållsanalys med en induktiv ansats och en deduktiv ansats användes i studien. Den induktiva delen bestod av öppna frågor och i den deduktiva delen användes MIRF-skalan. Resultat: Åtta underkategorier och tre huvudkategorier framträdde. Kategorierna resulterade i ett tema: " Upplevelser av att skapa en föräldraroll och hur relationen till barnen varierade och utvecklades känslomässigt över tid." Konklusion: Mödrarna uttryckte starka, mestadels positiva känslor gentemot sina barn. De mödrar som försökt att amma men fått avsluta amningen, var särskilt sårbara och i behov av stöd. Känslor av att vara en otillräcklig moder på grund av att inte kunna amma, kunde påverka moderns psykiska hälsa negativt och orsaka fördröjda moderskänslor.Background: It is common for mothers not to breastfeed today, still it is of low value by society. The research available about these mothers´ experiences of connection to their children, is limited. A district nurse should be able to support motherhood in different manners, for example by practical knowledge and in a way, that identifies mothers’ experiences about not breastfeeding. Aim: The purpose of this study was to describe how mothers who give formula milk to their infants, experience feelings and the relationship to their infants. Method: Ten interviews with mothers were conducted. Qualitative content analysis with an inductive approach and a deductive approach was used. The inductive part consisted of open questions and the MIRF-scale was used in the deductive part. Results: Eight subcategories and three main categories emerged. The categories resulted in a theme: “Experiences of creating a parenting roll and how the relationship with the children varied and developed emotionally over time.” Conclusion: The mothers expressed strong, mostly positive feelings towards their children. Mothers who tried to breastfeed and could not continue, were particularly vulnerable and in need of support. Feeling inadequate as a mother because of not being able to breastfeed, could affect the mother´s mental health negatively and cause delayed maternal feelings.

Memoria para optar al título profesional de Ingeniero Agrónomo Mención Producción AnimalEl presente trabajo tuvo por objetivo determinar el efecto de tres temperaturas (0°, 5°, 8°C) sobre la actividad respiratoria, color y parámetros sensoriales en hojas de berros y rúcula por un periodo de 15 días. La actividad respiratoria se determinó a partir de la medición de muestras gaseosas del espacio cabeza de un frasco de 1 L tras 1,5 horas de cierre, el color fue a través de los parámetros de luminosidad, croma y tono y las propiedades sensoriales según la aceptabilidad, apariencia, color, defectos y turgencia. La actividad respiratoria se midió cada 3 a 4 días, mientras que color y evaluación sensorial cada 6 ú 8 días. La actividad respiratoria disminuyó en todos los tratamientos para ambas especies en estudio. La medición del color indicó una tendencia a la disminución del color verde y aumento del amarillo en relación directa con el incremento de la temperatura. Respecto a los parámetros sensoriales, a 0°C se presentó la menor variación, disminuyendo solo el atributo aceptabilidad. En relación a lo anterior, en las hojas de berros, la menor actividad respiratoria se presentó a 0°C, con un promedio durante el ensayo de 49,1 mg CO2 kg-1 h-1, superior en 23,2 y 37,1 mg CO2 kg-1 h-1 a lo registrado a temperaturas de 5° y 8°C. Asimismo, en hojas de rúcula, la actividad respiratoria más baja se presentó a 0°C, con un promedio de 21,0 mg CO2 kg-1 h-1, superior en 26,5 y 38,1 unidades a lo obtenido a 5° y 8°C, respectivamente. Para ambos ensayos, los parámetros de color medidos instrumentalmente y las propiedades sensoriales evidenciaron el término de vida útil al séptimo día a temperaturas de 5° y 8°C, mientras que a 0°C se extendió hasta los 13 días, presentando el menor deterioro y por ende corresponde a la mejor alternativa, entre las estudiadas, para la conservación de hojas de berros y rúcula mínimamente procesada en fresco.

The aim of this study was to investigate milk consumption among children in a village in a developing country where access to milk during childhood may be limited. Another aim was to see if measurable information could demonstrate growth among children who drank milk. The data was collected through anthropometric measurements on 66 boys and girls (aged 5-6). Nutritional data from a selected group of parents of the participating children were done through 24-hour-recall, questions about meal arrangement, availability and attitudes about milk were asked. Result: Five-year-old girls who drank milk at home and in school were significantly taller compared to girls (5 yr) who did not drink milk, as well as taller than the girls (5 yrs) who drank milk only at home. Arm muscle area, and arm circumference was also significantly larger among the girls (5 yr) who drank milk. No significant differences were shown among the boys. Food consumption included more nutrients among children who drank milk, which might contribute to the growth effect among the girls (5 yrs). Consumption of milk was due to economic situations, access to school-milk or owning a cow. Conclusions: Some significant differences among 5-year-old girls were shown. Poverty was the main reason for not drinking milk, as well as lack of access to milk.Syftet med denna etnografiska studie var att undersöka mjölkkonsumtion bland barn i en by i ett utvecklingsland där tillgång till mjölk under barndomen kan vara begränsad. Syftet var även att se om mätbar information kan visa tillväxt hos barn som dricker mjölk. Data samlades in genom antropometriska mätningar på 66 pojkar och flickor (5-6 år). Kostdata hos en utvald grupp föräldrar till några av de barn som deltog i mätningarna har gjorts genom 24-timmars-intervjuer, där även frågor kring måltidsordningen, tillgänglighet och attityder kring mjölk ställdes. Resultat: Femåriga flickor som drack mjölk både i skolan och i hemmet visade sig vara signifikant längre än flickor (5 år) som inte drack mjölk, de var även längre än flickor (5 år) som bara drack mjölk i hemmet. Armmuskelarea och armomkrets var också signifikant större hos flickorna (5 år) som drack mjölk jämfört med de flickor som inte drack mjölk. Inga signifikanta skillnader gällande tillväxten visade sig hos pojkarna. Matkonsumtionen var mer varierad hos de barn som drack mjölk, vilket kan ha påverkat resultatet. Mjölkkonsumtionen berodde på ekonomi, tillgång till skolmjölk, brist på mjölk och kunskap om mjölk. Slutsats: Några signifikanta skillnader gällande tillväxten visade sig hos femåriga flickor. Fattigdom var största anledningen till att inte konsumera mjölk, även brist på mjölk i bostadsområdet. Barn som drack mjölk hade tillgång till mjölk i skolan och/eller i hemmet.

Full textAbstract:
While reading in deaf children has been the object of a number of studies, the reading abilitiesof children with mild and moderate hearing impairment and their relation to cognitiveprocessing have not received very much attention. Predictive factors of reading ability inhearing children are well known, with phonological and working memory abilities beingnecessary prerequisites for reading development. Existing studies suggest, however, thatcertain hearing-impaired children achieve a reading level comparable to that of hearingchildren in spite of impaired phonological abilities. In the present study, reading abilities anda range of cognitive processing abilities were measured in a group of hearing-impairedchildren and compared with hearing controls in equivalent school grades. Comparisons weremade at group and school-grade level, and the cognitive profile of hearing-impaired childrenat level with controls (those being within one standard deviation) was discussed. The resultssuggest that phonological abilities are important for the hearing-impaired children, but to alesser extent than for normally hearing children. The results also point towards workingmemoryabilities (particularly correct recall of phonemes in nonword repetition) as beingimportant for the possibility to compensate for impaired phonological abilities.
Emedan döva barns läsande har varit föremål för ett antal studier, har läsförmågan hos barnmed mild och måttlig hörselnedsättning och dennas relation till underliggande kognitiva förmågor inte fått mycket uppmärksamhet. Predicerande faktorer för läsförmågan hos hörande barn är väl kända och fonologisk förmåga och arbetsminneskapacitet utgör oumbärliga förutsättningar för läsutvecklingen. Befintliga studier antyder dock att vissa barn med mildoch måttlig hörselnedsättning uppnår en läsförmåga i nivå med hörande barns, trots nedsatt fonologisk förmåga. I föreliggande studie undersöktes läsförmågan och en rad kognitivaförmågor hos en grupp barn med mild och måttlig hörselnedsättning. Jämförelser gjordes medhörande kontroller på gruppnivå och per årskurs, och den kognitiva profilen hos de barn medhörselnedsättning som låg i nivå med kontrollerna (de som låg inom en standardavvikelse) diskuterades. Resultaten antyder att fonologiska förmågor var viktiga för läsning i sambandmed hörselnedsättning, men i mindre utsträckning än för normalhörande barn. Resultaten antyder också att arbetsminneskapacitet (framförallt korrekt fonemåtergivning vidnonordsrepetition) har betydelse för möjligheten att kompensera en nedsatt fonologiskförmåga.

Full textAbstract:
The capacity to process and to remember information is a basic condition for language ability and for coming reading ability. Reading ability is strongly connected to phonological awareness, receptive vocabulary knowledge and working memory capacity. In what way hearing impairment in children affects development of cognitive skills and later on reading ability is an area that has attracted minor attention for research.
The aim with this study was to investigate changes in cognitive skills and reading ability in children with mild or moderate hearing impairment after one year of progress and furthermore if any connections between any increases of the abilities were to be found. Comparisons were made with results from age adequate normal hearing children. Moreover prosodic ability on word-level was tested this year. Eleven Swedish children aged 7:6-10:10 years participated in this study. To illustrate progress of the abilities mentioned the SIPS computer test battery and furthermore some manually given tests for reading and prosodic abilities were used.
The results show a developmental trend for the children with hearing impairment on tests of working memory and reading comprehension. The least degree of development was found in the area of phonological skills. The children with hearing impairment showed in general the same capacity as normal hearing children on tests for the different abilities. In the area of working memory the children with hearing impairment had significant lower results on half of the tests than age adequate normal hearing children. Several strong connections were present for children with hearing impairment this year than last year, in-between cognitive skills and reading ability. Correlation appeared between age for insertion of hearing aid and test for decoding ability. Results on tests for prosodic ability reached ceiling effect.
Förmåga att bearbeta och minnas information ligger till grund för språkförmåga och är en förutsättning för kommande läsutveckling. Läsförmåga är starkt sammankopplad med fonologisk medvetenhet, receptivt ordförråd och arbetsminneskapacitet. På vilket sätt hörselnedsättning hos barn påverkar utveckling av kognitiva färdigheter och sedermera läsförmåga är dock ett område som inte tilldragit sig något större forskningsintresse.
Syftet med studien var att undersöka förändring av kognitiva färdigheter och läsförmåga hos barn med mild och måttlig hörselnedsättning under ett års tid, samt eventuella samband mellan förmågorna. Årets prestation jämfördes mot tidigare insamlat resultat från åldersmatchade normalhörande barn. Därutöver testades prosodisk förmåga på ordnivå. I studien deltog elva svenska barn i åldrarna 7:6-10:10 år. För att belysa utveckling av nämnda förmågor användes dels det datorbaserade testbatteriet SIPS samt manuella tester.
Resultaten visar en utvecklingstrend för gruppen barn med hörselnedsättning inom samtliga deltester som mätte arbetsminne och läsförståelse. Lägst grad av utveckling, där prestation låg i nivå med förra årets mätning, var inom fonologiska färdigheter. Vid jämförelse mellan grupperna presterade barnen med hörselnedsättning i allmänhet i nivå med åldersmatchade normalhörande barn inom de testade delområdena. Inom delområdet arbetsminne hade barnen med hörselnedsättning signifikant sämre resultat i hälften av deltesterna än de åldersmatchade normalhörande barnen. Barnen med hörselnedsättning hade år 2009 fler starka samband mellan deltester som mätte kognitiva färdigheter och läsförmåga, i jämförelse mot förra året. Samband fanns också mellan ålder för insättande av hörapparat och ett deltest som mätte avkodningsförmåga. Takeffekter fanns på tester av prosodisk förmåga på ordnivå för barnen med hörselnedsättning.

Full textAbstract:
Bakgrund Många mammor som fött barn prematurt önskar amning som uppfödning för sitt barn för bröstmjölkens immunologiska faktorer och som en kompensation för att graviditeten avslutats för tidigt. Amningens etablering kan vara komplicerad och kräva tålamod när barnet behöver vård. Beroende på barnets känslighet kan det ta olika lång tid tills barnet kan påbörja amningsträning. En av de viktigaste faktorerna för att amningen ska kunna etableras är att mamman får igång en tillräcklig mjölkproduktion motsvarande den mängd ett fullgånget barn skulle kräva. För att få igång en tillräcklig produktion är det bra att komma igång med urmjölkning så fort som möjligt efter barnets födelse. Mamman behöver stimulera mjölkproduktionen tills barnet ammar fullt. Syftet med studien var att belysa innebörden av urmjölkning för mammor vars barn fötts prematurt. Metod Det strategiska urvalet utgörs av sju mammor vars barn fötts före vecka 34 med erfarenhet av urmjölkning. Datainsamlingen består av öppna intervjuer och materialet har analyserades med en fenomenologisk hermeneutisk ansats. Resultatet visar att urmjölkning utförs i en oreflekterad ansträngning men att mammor är måna om de egna behoven samtidigt som behoven åsidosätts. Vårdkontexten kan kännas utlämnade och begränsande. Självtilliten får betydelse liksom strukturen. När utfallet inte blir som planerat kan sorgen innebära att förhålla sig till det som inte kan förändras. Känsla av hanterbarhet, begriplighet och meningsfullhet kan få betydelse för processen. Slutsats Ur ett vårdvetenskapligt perspektiv blir det betydelsefullt att utgå från den enskilda mammans upplevelser av urmjölkningen och stärka en god självtillit.Background Many mothers who have given birth premature wish to breast feed their children for immunological reasons and as a compensation for a pregnancy that ended too early. The breast feeding may be complicated and in need of great patience as the child might need health care. Depending of the baby´s sensitivity it can vary in time for a child to start breast feeding. One of the important reasons for the mother to get her breast feeding started is to make milk production start, corresponding to the amount of milk that a fully mature baby would need. To get a sufficient production it is important to start emptying the breasts quick as possible after having given full extend. Aim with the study was to illuminate the meaning of emptying the breasts for mothers whos baby was born premature. Method Seven mothers who had given birth before week 34 and had experienced emptying breasts. The data collection come from interviews and the results have been analyzed by a fenomenological hermenutichal approach. Results shows that emptying the breasts is done without any effort but that mothers are eager to look at their own needs at the same time as their own needs are being put aside. The hospital care can make the women feel left out and controlled. Self-confidence gets important as well as the structure. When the result is not as you had planned sadness make you realize that things cannot be changed. The feeling of managing, understanding and meaningfulness fills you up. Conclusions looking at it from a scientific perspective it is very important to consider the individual mothers experience in how to empty the breasts from milk and how to strengthen her self-confidence.

The study sought to determine whether there is evidence for the presence of residual (chronic) deleterious effects on cognition due to repetitive mild traumatic brain injury in top team university level rugby players, using ImPACT 3.0, Trail Making Test (TMT) and Digit Span. The initial sample of 48 participants was divided into groups; Rugby (n = 30) and Controls (n = 18), Rugby Forwards (n = 14) and Rugby Backs (n = 16). A reduced sample (N = 31) comprised of Rugby (n = 20) and Controls (n = 11), Rugby Forwards (n = 9) and Rugby Backs (n = 11). Comparative subgroups were equivalent for estimated IQ but not for age and educational level in the full sample; in the reduced sample there was equivalence for all three variables of age, education and estimated IQ. All cognitive test measures were subjected to independent t-test analyses between groups at the pre- and post-season, and dependent t-test analyses for Rugby and Controls at pre- versus post-season. Overall, the results implicated the presence of deleterious effects of concussive events on Rugby players in the areas of speed of information processing, working memory and impulse control. Significant practice effects were found on the TMT and Digit Span for controls, but not on ImPACT 3.0, supporting the use of this computer-based programme in the sports management context.

Resumo: Esta pesquisa teve como objetivo avaliar o desempenho de um sistema asséptico piloto para a produção de leite UHT (Ultra Hight-Temperature), com capacidade de 1.000 L/h, em embalagens flexíveis institucionais do tipo Bag-in-box (BIB). As embalagens estudadas eram compostas de um filme de polietileno de baixa densidade (PEBD) e um filme de polietileno tereftalato metalizado (PETmet), com volume de 2.000 mL, desenvolvido especialmente para o envase asséptico de produtos lácteos. Leite cru refrigerado tipo A foi utilizado como matéria-prima. O envase do leite UHT foi realizado através de uma dosadeira semi-automática dentro de uma Sala Limpa ISO posicionada sobre o bocal de enchimento das embalagens. O sistema foi avaliado através da identificação e monitoramento de pontos de controle do processo, testes de esterilidade comercial, análises sensorial e físico-química do produto, bem como avaliações da embalagem. O desempenho das embalagens BIB foi avaliado através de ensaios de caracterização, integridade do sistema e estudos de estabilidade microbiana e testes de efetividade de esterilização. As embalagens foram esterilizadas com o uso de radiação ionizante (gama), com dose de 15 kGy. Os ensaios foram conduzidos através da produção de 4 lotes experimentais de leite UHT, obtido em trocador de calor a placas (140 °C por 5 s). A taxa de defeito encontrada nos testes de esterilidade comercial variou entre 0 e 6,7%, sendo que a principal causa de defeitos foi associada aos problemas inerentes a operacionalidade da linha, como falhas nas vedações das junções de tubulações e bombas centrífugas. Os resultados da avaliação dos pontos de controle do processo e embalagem indicaram um bom desempenho do sistema, justificado pela ausência de microorganismos viáveis. O leite UHT acondicionado nas embalagens BIB teve sua vida de prateleira estimada em até 27 semanas de estocagem, valor este muito superior quando comparado às amostras controle de leite UHT comercial, acondicionado em embalagens laminadas cartonadas, que teve sua vida de prateleira estimada em 19 semanas. A diferença de estabilidade físico-química, microbiológica e sensorial entre as amostras processadas e a comercial foi associada às propriedades de barreira das estruturas das embalagens à luz e ao oxigênio, bem como pela qualidade da matéria-prima utilizada. O sistema asséptico piloto avaliado correspondeu às expectativas de desempenho e atendeu aos requisitos estabelecidos pelo Codex Alimentarius. Concluiu-se que o sistema apresenta potencial para utilização por indústrias de laticínios visando atender o mercado institucional de leite longa vida
Abstract: The aim of this research was to evaluate the performance of an aseptic pilot system for the production of Ultra High Temperature (UHT) milk, with 1.000 L/h capacity, filled in flexible institutional packages Bag-in-box (BIB) type. The BIB packages were constructed with one layer of low density polyethylene film (LDPE) and another one of metalized polyethylene terephthalate film (PETmet), with 2.000 mL capacity, specially developed for the aseptic filling of dairy products. Type-A milk was used as raw material and the UHT milk filling was made by a semiautomatic machine located inside a ISO Clean room. The system was evaluated by the identification and monitoring of the control points during the process and also by commercial sterility tests, sensorial and physical-chemistry analysis and packages evaluations. The BIB packages were sterilized by gamma radiation with minimum doses of 15 kGy. The assays were conducted by the production of 4 experimental batches processed in a plate heat exchanger (140 °C/5 s). The defect rates founded were between 0 and 6.7% and these values can be explained by problems linked to the pilot plant operation, like failures in the connections of pipes and centrifugal pumps. The results of the control points evaluation and also BIB packages showed a good performance of the entire process, justified by the absence of viable microorganisms. The milk filled in BIB packages targeted until 27 weeks of shelf life, a superior value when it was compared to the commercial UHT samples, which targeted just 19 weeks. The difference of physical-chemistry, microbiology and sensory stability between the processed samples and the commercial one was associated to the oxygen and light barriers properties and also to the raw milk quality used during the processes. The pilot aseptic system evaluated attended to the Codex Alimentarius requirements and it could be concluded that the system showed potential for application in dairy industry in view of the long life milk institutional market

Familjer med små barn som inte tål mjölk upplever att de behöver praktisk hjälp med mat och måltider. Syftet var att undersöka om, och i så fall hur, recept kan möta de behov som familjerna upplever att de har. Totalt 15 recept togs fram. På två workshoppar fick 11 familjer testa recepten genom att provlaga och smaka de tillagade måltiderna. Under workshopparna intervjuades föräldrarna om vad de tyckte om recepten och om vilka behov de har. Resultatet visar att recept kan vara en praktisk hjälp för familjer med mjölkallergi – om recepten tar hänsyn till de behov kring mat som familjerna har. Familjernas behov är motstridiga, men det går att sammanföra dem i recept. För att kunna kombinera deras behov av bekvämlighet och ansvar för näringsriktig mat måste det vara snabb och enkel mat som samtidigt utgår ifrån små barns näringsbehov utan att innehålla mjölk. Även identitet, som är kopplat till smak, är viktigt. God mat är synonymt med bekanta smaker som är vanliga i många barnfamiljer.Families with small children who are allergic to milk experience that they require practical advice on food and meals. The purpose of this study was to investigate if, and if so how, recipes can meet the needs regarding food and meals that these families feel that they have. Total 15 recipes were developed. These were tested by 11 families by cooking and tasting the meals at two workshops. During both workshops the parents were interviewed to find out their opinions on the recipes as well as their needs. The results indicate that recipes may be a useful remedy for families with milk allergy, given that the recipes consider the families’ very needs as regarding to food. The needs of the families’ are contradictory, however they can be summed up into recipes. In order to combine the families’ need for ease and responsibility for nutritious food, the food must be quick and simple but still emanate from the nutritional requirements for small children with milk allergy. Likewise identity related to taste is important. Good food is synonymous with well-known tastes for families with children.

Cette étude comporte 3 grandes parties. La première traite de la micropropagation, ainsi que des possibilités d'imiter et d'entretenir des cultures de tissus organogènes ou non à partir de vitrosemis. Ce travail fait apparaître un comportement particulier du mélèze vis-à-vis de la BAP : concentrations élevées pour induire un bourgeonnement adventif, apparition de phénomènes de vitrification, et effet remanent. La deuxième partie a été consacrée à la préparation et à la culture de protoplastes. Les meilleurs résultats ont été obtenus avec des cals cotylédonaires de 4 semaines, produits dans l'obscurité. Plusieurs paramètres du milieu se sont révélés particulièrement importants : notamment la fraction azotée : 40 mm de glutamine, et la fraction glucidique composée de mannitol et de glucose chacun à 0,38 m. Dans ces conditions, des microcals d'environ 30 cellules ont été observées. La troisième partie a été consacrée au fonctionnement respiratoire des protoplastes : la respiration de ceux-ci est importante durant les premiers jours de culture. Après 20 jours on observe les premiers signes de dégradation des capacités d'oxydo-réduction qui se traduisent par un blocage de l'activité mitotique

Full textAbstract:
Mestrado em Gestão e Estratégia IndustrialCom o aparecimento da crise económica, as marcas de distribuidor entraram no mercado como uma alternativa a preços acessíveis e, ao longo dos anos, sofreram uma crescente popularidade entre os consumidores devido à sua melhoria de qualidade. Atualmente, as marcas de distribuidor têm uma grande presença no mercado e mantêm uma grande competitividade com as marcas de fabricante. Neste sentido, o presente estudo pretende conhecer as preferências dos consumidores de dois produtos opostos quanto à penetração das marcas de distribuidor, neste caso, o leite e as tabletes de chocolate. Para tal, pretende identificar os atributos mais valorizados pelos consumidores na escolha destes dois produtos e compreender se existem diferenças na preferência pela "marca" entre os mesmos. A técnica de pesquisa utilizada foi a Análise Conjunta, onde foram geradas dezasseis combinações para cada um dos produtos, baseadas em três atributos chave e seus respetivos níveis. Em ambos os produtos, a marca Continente é apresentada como um dos níveis do atributo "marca" porque foi esta a marca de distribuidor escolhida para o estudo. As combinações geradas foram avaliadas pelos consumidores através de um questionário presencial, onde obteve-se uma amostra não probabilística por conveniência de 210 inquiridos. O resultado retirado da análise aos questionários revela que o atributo mais valorizado pelos consumidores na escolha de leite é o teor de gordura, seguido da marca e do preço, e o atributo mais valorizado na escolha de tabletes de chocolate é o tipo de chocolate, seguindo-se a marca e o preço.
With the appearance of the economic crisis, private labels entered the market as an alternative, providing accessible prices and, over the years, experienced a growing popularity among consumers due to its quality improvement. Nowadays, the private labels have a big market presence and are able to compete with the manufacturer brands. Regarding this matter, the present study aims to understand the preferences of the consumers of the two opposite products in terms of penetration of private labels, in this case, milk and chocolate bars. For this purpose, it intends to identify the attributes that are most valued by consumers when choosing one of these products and understand if there are differences in the preference/utility of the "brand" attribute between these products. The searching technique used was the Conjoint Analysis, where sixteen combinations for each product, based on three key attributes and their respective levels, were generated. In both products, the Continente brand is presented as one of the levels of the brand attribute because this was the private label chosen for the study. The generated combinations were evaluated by consumers through a classroom questionnaire, which was obtained from a non-probabilistic convenience sample of 210 interviewed. The result obtained from the questionnaire analysis reveals that the most valued attribute by consumers in choosing milk is the fat, followed by brand and price, and the most valued attribute in choosing chocolate bars is the type of chocolate, followed by brand and the price.

Após a constatação da escassez de estudos realizados com vegetais crus na busca por novas estirpes de bactérias láticas (BAL) produtoras de bacteriocinas e diante do potencial tecnológico da aplicação destas cepas tanto como agentes de conservação em alimento, bem como cultura probiótica em alimentos funcionais, este estudo objetivou isolar e identificar cepas de bactérias láticas potencialmente bacteriocinogênicas de amostras de rúcula obtidas no comércio local de São Paulo, SP - Brasil, identificar e caracterizar as bacteriocinas produzidas pelos isolados e avaliar o potencial probiótico dos isolados testando sua sobrevivência no modelo dinâmico do trato gastrointestinal TNO gastro-Intestinal Model - TIM-1 disponível no TNO (The Netherlands Organization for Applied Scientific Research) divisão Quality of Life (Zeist, Holanda). A produção de bacteriocinas neste modelo também foi avaliada, comparando-se com L. sakei 2a, também produtora de bacteriocinas e ainda avaliou-se a interferência na viabilidade de E. faecium LMA1. A cepa Lactococcus lactis subsp. lactis MK02R de rúcula produziu uma bacteriocina sensível à enzimas proteolíticas, termoestável e não influenciada pelo pH, sendo capaz de inibir Enterococcus faecium, Lactobacillus sakei, Listeria innocua, Lactobacillus delbrueckii e Listeria Monocytogenes de diferentes grupos sorológicos. Os ensaios genéticos utilizando primers Nisf e Nisr confirmaram que a bacteriocina MK02R é uma nisina, apresentando uma alteração dos aminoácidos no peptídeo líder em relação às nisinas A, Z, Q, F e U, porém com a estrutura do peptídeo maduro idêntica ao da nisina F. Estes resultados foram confirmados por espectrometria de massas de amostras purificadas por HPLC. L. lactis MK02R resistiu à passagem no modelo dinâmico TIM-1, apresentando uma alta capacidade de sobreviver nas condições simuladas do trato gastrointestinal humano. Entretanto, não foi capaz de causar a redução no número de E. faecium LMA1. Em contrapartida, L. sakei 2a, mesmo apresentando uma sobrevivência menor, foi capaz de causar uma redução de 70% na população de E. faecium LMA1 no ambiente simulado do TGI. Não foi detectada atividade residual da ação antimicrobiana das bacteriocinas produzidas por L. lactis MK02R ou L. sakei 2a após a passagem pelo modelo dinâmico TIM-1. Estes resultados evidenciam a possível aplicação de L. lactis MK02R como um agente de controle biológico na conservação de alimentos e também como uma cultura potencialmente probiótica.Given the scarcity of studies performed with raw vegetables addressing the search for new bacteriocinogenic strains of lactic acid bacteria (LAB) and considering the technological application of these strains as food preservatives and probiotic cultures in functional foods, this study was aimed at isolation and identification of bacteriocinogenic LAB strains from samples of rocket salad obtained in the local market of São Paulo, SP - Brazil, subsequent characterization of the bacteriocins produced by these LABs and evaluation of their probiotic potential by testing their survival in the dynamic gastrointestinal model TNO gastro- Intestinal-Model - TIM-1, available at the TNO (Netherlands Organization for Applied Scientific Research) Quality of Life division (Zeist, Netherlands). The studies in the TIM-1 model were also done with another bacteriocinogenic strain L. sakei 2a for comparison, evaluating their interference on the viability of E. faecium LMA1. The bacteriocin produced by strain Lactococcus lactis subsp. lactis MK02R isolated from rocket salad was sensitive to proteolytic enzymes, heat-stable and not influenced by the pH. The bacteriocin inhibited the growth of Enterococcus faecium, Lactobacillus sakei, Listeria innocua, Lactobacillus delbrueckii the primers Nisf and Nisr indicated that the bacteriocin produced by the strain MK02R is a nisin, with a change in the amino acid sequence of the leader peptide when compared to nisin A, Z, Q, U and F, but with the structure of the mature peptide homologous to that of nisin F. These results were confirmed by mass spectrometry of purified samples obtained by HPLC. L. lactis MK02R withstood the test in the dynamic model TIM-1, presenting capability to survive in the simulated conditions of the human gastrointestinal tract. However, the strain was not able to cause a reduction in the number of E. faecium LMA1. On the other hand, L. sakei 2a, even presenting lower survival, was able to cause 70% reduction in the population of E. faecium LMA1 in the gut simulated environment. No residual antimicrobial activity of bacteriocin produced by L. lactis MK02R or L. sakei 2a was detected after the transit through the dynamic model TIM-1. These results demonstrate the possible application of L. lactis MK02R both as a biocontrol agent in food preservation and as a potentially probiotic culture.

This dissertation aims to analyze North America television series developed over the last thirty years to understand its narrative structures and to check differences and similarities in how these programs develop their content over time. In order to do so, at first a literature review will be done to define the state of the art of other studies that have the same theme. Then methodological procedures will be used to select the ideal research object and to assist in the analysis of that content. To achieve that, this work uses the ideas of Arlindo Machado, Boris Tomachevski, Robert McKee and Steven Johnson as reference. It also analyzes the well-?known TV shows NYPD Blue (1993 -? 2005), The Sopranos (1999 -? 2007) and Breaking Bad (2008 -? 2013) and proposes another form of narrative analysis for television series.

Full textAbstract:
Carbon nanotubes, graphene and nano sized core shell rubber particles have all been extensively researched for their capability to improve mechanical properties of thermoset resins. However, there has been a lack of research on their evaluation for energy absorption in high velocity impact scenarios, and the fundamental mechanics of their failure mechanisms during highly dynamic stress transfer through the matrix. This fundamental research is essential for laying the foundation for improvement in ballistic performance in composite armor. In hard armor applications, energy absorption is largely accomplished through delamination between plies of the composite laminate. This energy absorption is accomplished through two mechanisms. The first being the elongation of the fiber reinforcement contained in the resin matrix, and the second is the propagation of the crack in between the discreet fabric plies. This research aims to fundamentally study the energy absorption characteristics of various nano-particles as reinforcements in thermoset resin for high velocity impact applications. Multiple morphologies will be evaluated through use of platelet, tubular and spherical shaped nano-particles. Evaluations of the effect on stress transfer through the matrix due to the combination of nano sized and micro scale particles of milled fiber is conducted. Three different nano-particles are utilized, specifically, multi-walled carbon nanotubes, graphene, and core shell rubber particles. The difference in surface area, aspect ratio and molecular structure between the tube, platelet and spherical nano-particles causes energy absorption through different failure mechanisms. This changes the impact performance of composite panels enhanced with the nano-particle fillers. Composite panels made through the use of dispersing the various nano-particles in a non-contact planetary mixer, are evaluated through various dynamic and static testing, including unnotched cantilever beam impact, mixed mode fracture toughness, split-Hopkinson bar, and ballistic V50 testing. The unnotched cantilever beam testing showed that the addition of milled fiber degraded the impact resistance of the samples. Addition of graphene nano platelets unilaterally degraded impact resistance through the unnotched cantilever beam testing. 1.5% loading of MWCNT showed the greatest increase in impact resistance, with a 43% increase over baseline. Determining the critical load for mixed mode interlaminar shear testing can be difficult for composite panels that bend without breaking. An iterative technique of optimizing the coefficient of determination, R2, in linear regression is developed for objectively determining the point of non-linearity for critical load. This allows for a mathematical method of determination; thereby eliminating any subjective decision of choosing where the data becomes non-linear. The core shell rubber nano particles showed the greatest strain energy release rate with an exponential improvement over the baseline results. Synergistic effects between nano and micro sized particles in the resin matrix during transfer of the stress wave were created and evaluated. Loadings of 1% milled carbon fiber enhanced the V50 ballistic performance of both carbon nanotube and core shell rubber particles in the resin matrix. However, the addition of milled carbon fiber degrades the impact resistance of all nano-particle enhanced resin matrices. Therefore, benefits gained from the addition of micro-sized particles in combination with nano-sized particles, are only seen in high energy impact scenarios with micro second durations. Loadings of 1% core shell rubber particles and 1% milled carbon fiber have an improvement of 8% in V50 ballistic performance over the baseline epoxy sample for 44 mag single wad cutter gas check projectiles. Loadings of 1% multi-walled carbon nanotubes with 1% milled carbon fiber have an improvement of 7.3% in V50 ballistic performance over the baseline epoxy sample. The failure mechanism of the various nano-particle enhanced resin matrices during the ballistic event is discussed through the use of scanning electron microscope images and Raman spectroscopy of the panels after failure. The Raman spectroscopy data shows a Raman shift for the fibers that had an enhancement in the V50 performance through the use of nano-particles. The Raman band for Kevlar centered at 1,649 cm-1 stemming from the stretching of the C==O bond of the fiber shows to be more sensitive to the residual axial strain, while the Raman band centered at 1,611 cm-1 stemming from the C-C phenyl ring is minimally affected for the CSR enhanced panels due to the failure mechanism of the CSR particles during crack propagation.Ph.D.

Full textAbstract:
Refiners are used in the pulp and paper industry to separate wood chips into individual fibres and to develop the morphology of fibres to be suitable for the type and grade of paper to be produced. Within a refiner are discs, at least one of which rotates at high speed and all of which are lined with radial patterns of bars on their opposing surfaces. As the chips and fibres are accelerated through the refiner, compressive and shear forces are applied to them by the bars as the opposed discs cross each other. Experiments have shown that the contact mechanics of bar-crossings are a significant factor in the development of fibre properties. To investigate the contact mechanics in operating refiners, a prototype piezoelectric-based sensor was developed to measure the forces applied by the bars. This work re-designs the prototype sensor to function at the mill-scale, and validates the design in two trials. Performance during these trials is presented along with an in-depth analysis of the recorded data.
Arrays of force sensors were installed in two single-disc refiners: a pilot-scale machine operating as a primary stage, and a mill-scale machine operating as a rejects stage. In the rejects refiner, mean forces were highest at the periphery of the refining zone, while in the primary stage, mean forces were higher at the sensor closest to the refiner axis. Higher coefficients of friction were measured in the primary stage refiner, which also showed less active bar-crossings. Distributions of peak force values were generated for a range of standard operating conditions. Primary stage refining showed near decreasing exponential distributions, while rejects refining showed skewed normal distributions. These results indicate a fundamental difference in the behavior of these refiners, which is explained in terms of the processing stage of the wood fibre and scale of the refiner.
Past laboratory experiments in a single-bar refiner have shown that pulp consistency can greatly affect the contact mechanics of bar-crossing impacts. The effect was observed as a positive correlation between the coefficient of friction and the mass fraction of fibre in the stock, known as the consistency. In the present work, a similar correlation was found in the primary stage refiner, but only in the sensor closest to the refiner axis. No significant changes in the coefficient of friction were observed in the rejects refiner; however, only a small range of consistencies was tested. These initial findings suggest relationships found in past laboratory tests may translate to larger-scale equipment.
The clashing of plates during refining accelerates bar wear, and delays production. An investigation of the ability of the sensor to predict plate clash was conducted. The force sensors consistently provided advanced warning of a clash event, many seconds before the accelerometer-based plate protection system currently in use by the mill. A sensitivity study showed that the new system was able to outperform the accelerometer system over a range of detection settings, and that the accelerometer could not be tuned to match the performance of the new system.

A procura de snacks convenientes e nutritivos aliada ao ritmo acelerado a que vivem os consumidores despoletou o crescente consumo de barras com proteína nos últimos anos. Respondendo a esta tendência, o objetivo deste trabalho incidiu no desenvolvimento de uma barra de cereais rica em proteína. Foram preparadas barras de cereais através da mistura de ingredientes secos envolvidos pelo ligante (resultante da cozedura a uma temperatura superior a 100ºC de ingredientes ligantes). Foram testadas 9 proteínas em pó de origem vegetal e animal (leite, soro de leite, trigo, ervilha e alga), que foram incorporadas nos ingredientes ligantes. Este trabalho permitiu concluir sobre a viabilidade tecnológica das proteínas no ligante, identificando-se dois fatores chave: a temperatura (efeito do seu aumento no desenvolvimento de um escurecimento ou consistência indesejáveis ou pela agregação/gelificação das proteínas) e a solubilidade (prevenção de partículas em suspensão). Adicionalmente, também se observou o seu impacto organolético nas barras (cor, sabor e textura). No geral, concluiu-se que as proteínas vegetais apresentaram melhor desempenho na cozedura do ligante, porém foram mais desafiantes sensorialmente (má palatibilidade), à exceção da proteína de trigo solúvel, que permitiu obter uma formulação mais promissora para ser testada a nível industrial. Neste protótipo, consideraram-se bastante próximos os resultados obtidos em amostras no teor de proteína (por 100 g) pelos cálculos nutricionais (18,19 g), pela análise NIR (18,67 ± 0,47 g) e no laboratório acreditado externo (18,02 g). Os valores obtidos no teor de humidade pelo método NIR (7,92 ± 0,12 %) e gravimétrico (7,92 ± 0,18 %), bem como, a atividade da atividade da água (0,445 ± 0,004) encontraram-se consonantes com os referenciados para produtos de humidade intermédia. À escala industrial obtiveram-se resultados insatisfatórios no desempenho do ligante: a sua consistência densa não permitiu a mistura com os ingredientes secos no primeiro lote; a aglomeração da proteína no segundo lote inviabilizou a formação de barras. No entanto, ressalva-se o facto de dois lotes não serem suficientes para otimizar todos os parâmetros de processo à escala industrial quando se trata de um desenvolvimento pioneiro. Neste âmbito, diferentes alterações podem ser consideradas, por exemplo, testar diferentes temperaturas de cozedura; adquirir um agitador para o tanque de cozedura mais eficaz; incluir a etapa de reconstituição de proteína em água antes da etapa de cozedura ou pela alteração da sequência de adição de ingredientes no ligante antes da etapa de cozedura. Em termos de reformulação da composição do ligante, a validação e teste à escala laboratorial de proteínas em pó e extrudidos de proteína alternativos; a incorporação de misturas de proteínas; ou o revestimento parcial ou total de coberturas proteicas são também possíveis soluções para trabalhos experimentais futuros.The growing demand for convenient and nutritious snacks combined with the accelerated pace at which consumers live has triggered the increasing consumption of protein bars in the recent years. Answering to this trend, the objective of this work focused on the development of a protein-rich cereal bar. Cereal bars were prepared by mixing dry ingredients and binder (resulting from cooking at a temperature above 100ºC of binding ingredients). 9 protein powder of plant and animal origin (milk, whey, wheat, pea and algae) were tested and included in the binding ingredients. This work allowed to conclude on the technological viability of proteins added to the binder, identifying two key factors: temperature (effect of its increase on the development of undesirable darkening or consistency or by the aggregation/gelling of proteins) and solubility (prevention of particle suspension). In addition, its organoleptic impact on bars (colour, taste and texture) was also observed. Overall, it was concluded that vegetable proteins presented better performance in binder cooking, but were more sensory challenging (poor palatability), with the exception of soluble wheat protein, which made it possible to obtain a suitable formulation for industrial testing. In this prototype, the results obtained for samples in terms of the protein content (per 100g) were considered to be very close by theoritical calculations (18,19g), by NIR analysis (18,67 ± 0,47g) and by the accredited external laboratory (18,02g). The values obtained for moisture content by the NIR (7,92 ± 0,12 %) and gravimetric (7,92 ± 0,18 %) methods, as well as water activity (0,445 ± 0,004) were aligned with those referenced for intermediate moisture products. On industrial scale, unsatisfactory results were obtained in the binder's performance: its thick consistency didn’t allow mixing with the dried ingredients in the first batch; the protein agglomeration in the second batch made it inoperable to form bars. However, it should be noted that two batches are not sufficient to optimize all process parameters on an industrial scale when it comes to pioneering development. In this regard, different changes may be considered, for example, testing different cooking temperatures; purchase a stirrer more effective for the cooking tank; include the step of reconstituting protein in water prior to the cooking or by changing the ingredient addition sequence in the binder prior to the cooking step. In terms of reformulation of the binder composition, laboratory validation and testing of alternative protein powders and extrudates; the incorporation of protein mixtures; or partial or full coating of protein coatings are also possible solutions for future experimental work.
