Influência dos parâmetros de regulagem de máquina nas características físicas de malhas de poliamida/elastano / Influence of machine parameters on the physical properties of polyamide/elastane single jersey fabrics

Vasconcelos, Fernando Barros de 14 December 2012 (has links)
O comportamento dinamométrico de malhas submetidas à tração é geralmente inadequado para atender aos padrões atuais de conforto e desempenho e, portanto, fibras elastoméricas são cada vez mais utilizadas em conjunto com algodão, viscose, poliamida e poliéster para conferir aos artigos um maior grau de alongamento e uma melhor recuperação elástica. Dessa forma as características desses produtos estão amplamente associadas ao fio de elastano e sua utilização. No entanto as relações entre a proporção de elastano, a alimentação de fio rígido e as propriedades físicas obtidas nas malhas é algo ainda pouco estudado. O objetivo desse trabalho é estudar e definir essas relações através do planejamento de experimentos em malhas monofrontura de poliamida/elastano. Foram alteradas condições de alimentação do fio de poliamida (LFA) e tensão do elastano e, após relaxamento, medidas várias propriedades das malhas produzidas como gramatura, largura, densidade, espessura, porcentagem de elastano, permeabilidade ao vapor, alongamento e elasticidade. Foi possível observar como a tensão de elastano é preponderante na densidade e na porcentagem de elastano, enquanto o LFA da poliamida é predominante na espessura e alongamento da malha, enquanto a largura, a elasticidade e a permeabilidade ao vapor não sofrem influências significativas de nenhum dos dois fatores analisados. / The dynamometric behavior of knits subjected to traction is generally inadequate to meet current standards of comfort and performance and, therefore, elastomeric fibers are increasingly used in combination with cotton, viscose, polyamide and polyester to give to these articles a greater degree of elongation and better elastic recovery. Thus the characteristics of these products are widely associated with elastane yarn. However the relationship between the elastic yarn rate, the loop length and the physical properties obtained in the jersey knit is somewhat poorly studied. The aim of this work is to study and define these relationships using design of experiments in polyamide / elastane single jersey knits. The polyamide feed (LFA) and elastane tension were changed and, after relaxation, measurements of jersey properties were done, such as mass per unit area, width, density, thickness, percentage of elastane, water vapor permeability, elongation and elasticity. It was possible to observe how elastane tension is leading to density and percentage of spandex, while polyamide LFA is predominant in the thickness and elongation, since the width, elasticity and vapor permeability are not influenced by either of the two significant factors

Discontinuités et systèmes spatiaux. La combinaison île/frontière à travers les exemples de Jersey, de Saint-Pierre-et-Miquelon et de Trinidad

Fleury, Christian 04 October 2006 (has links) (PDF)
L'espace est hétérogène. Il est donc discontinu. Île et frontière sont des discontinuités fortes, traversées par des systèmes. Ce sont aussi des objets géographiques ambivalents, ouverts et fermés. La frontière implique le frottement plus ou moins rugueux de deux entités politiques. L'ambivalence frontalière est alimentée par des altérités qui se combinent, s'affrontent, s'attirent ou se repoussent selon des intensités différentes et à différents niveaux des échelles spatiale et sociale. Ces altérités sont diverses. Fondamentalement politiques et juridiques, elles sont également culturelles, économiques, fiscales. Deux questions sont posées à propos des trois termes de la comparaison : comment cette combinaison de discontinuités agit-elle sur les relations entre deux espaces terrestres proches, l'insulaire et le continental ? Inversement, comment les systèmes spatiaux mis en œuvre dans l'exercice de la relation agissent-ils sur ces discontinuités ? Par ailleurs, la mer est sous-jacente à la combinaison île-frontière. Son partage entre États est un phénomène géopolitique dynamique et récent. La question de cette appropriation confrontée aux pratiques socio-économiques – la pêche dans les trois cas étudiés, et l'extraction des hydrocarbures, dans deux sur trois – prend ici une dimension particulière. Cette thèse comprend donc une étude des processus d'appropriation de l'espace marin, qui vont des modalités de délimitation d'un espace par essence complexe en raison de sa structure à la fois horizontale et verticale, à son administration et aux mécanismes de transgression négociée, destinés à adapter sa spécificité aux rigidités des constructions territoriales.

A Phenomenological Case Study of a Principal Leadership: The Influence of Mr. Clark's Leadership on Students, Teachers and Administrators at Eastside High School

Miller, Olandha Pinky 11 August 2011 (has links)
Joe Louis Clark was the principal of Eastside High School (EHS) located in Paterson, New Jersey from 1982 to 1989. The purpose of this phenomenological case study was to explore Mr. Clark’s leadership style as principal of EHS, and to investigate from the point of view of Mr. Clark’s former students, teachers, and administrators what, if any effect, his leadership style had at EHS, as well as on his students, teachers, and administrators’ lives during and subsequent to their time at EHS. I conducted this investigation by giving voice to my classmates, teachers, administrators and myself. I graduated from EHS during Mr. Clark’s tenure and I am a member of his first graduating class in 1986. When Mr. Clark arrived as principal, EHS was characterized by large numbers of students living at or below the poverty line, overcrowded classrooms, and outdated resources. Additionally, there were issues such as: high dropout rates, drugs, teenage pregnancy, violence towards students and teachers. In an attempt to raise the students’ Minimum Basic Skills Test scores and eliminate the violence at EHS, Mr. Clark was hired as the principal. Through face-to-face and telephone semi-structured, open ended in-depth interviews with twenty-two participants, I uncovered personal views of Mr. Clark’s leadership style. Mr. Clark used a leadership style that was characterized by the informants as autocratic, directive, charismatic and caring. The voices of his students, teachers, and administrators speak volumes about the strategies he developed that made an impact on their lives in addition to reforming EHS.

Taming debauchery : church discipline in the Presbytery of St Andrews and the American colonies of New Jersey and New York, 1750-1800

Huntley, Heather Maurine January 2004 (has links)
Creating moralistic societies was a concern of the churches and the governments of Scotland and the American colonies of New York and New Jersey in the eighteenth century. However, church and state relations in Scotland and the American colonies were dissimilar and the differences manifested themselves in the various approaches taken by each body to suppress the immoral behaviour that existed in both countries. By examining the disciplinary procedures and cases in the parishes of the Presbytery of St Andrews and the Presbyterian churches in the colonies of New York and New Jersey, these divergences emerge and illuminate the relationship between church and state. The Church of Scotland was recognized as the established church by the state and was allowed to implement its own Presbyterian system of government and discipline according to its ecclesiastical doctrines and theological beliefs. The state utilized its legal systems to punish and correct immoral behaviour. In Scotland, the two systems had defined boundaries and complemented one another in their efforts to suppress immorality. However, not only did the American colonies lack a centralized state until 1776, but the colonies also lacked an established church. Alternatively, each colony had its own governing bodies, judicial systems, and a variety of church denominations. The Presbyterian Church, one of the many churches in the colonies of New York and New Jersey, utilised a Presbyterian system of ecclesiastical discipline in order to supplement the judicial systems' attempts to suppress immorality within the colonies.

Suplementação de vacas HPB e vacas 1/2 HPB 1/2 Jersey mantidas em pastagem tropical com o éster isopropílico do análogo de metionina (HMBi) / Supplementation of BWH cows and ½ BWH ½ Jersey cows kept in tropical pasture with the isopropyl ester of methionine analog (HMBi)

Leandro Ferreira Greco 31 July 2008 (has links)
No presente experimento, foi testada a inclusão do éster isopropílico do análogo de metionina (HMBi) no concentrado de vacas Holandesas (HPB) e vacas ½ HPB ½ Jersey mantidas em pastagens de capim Elefante, com o objetivo de atingir relação entre lisina e metionina de 3:1 na proteína metabolizável. As variáveis avaliadas foram a produção e composição de leite. A massa de forragem e as composições nutricional e morfológica da pastagem também foram avaliadas. Foram utilizadas 16 vacas HPB e 12 vacas ½ HPB ½ Jersey, com aproximadamente 150 dias em lactação no início do período experimental. A pastagem de capim Elefante foi manejada em sistema rotacionado com dois dias de ocupação e período de descanso variável, determinado pela altura do dossel de 1m para a entrada dos animais no piquete. A pastagem foi adubada com 80 kg de N por ciclo de pastejo. As vacas experimentais faziam o pastejo no primeiro dia de ocupação e animais extras do rebanho realizavam o repasse no segundo dia de ocupação de cada piquete, garantindo que o resíduo pós pastejo ficasse em torno de 40 cm. A pastagem continha em média 22% de PB, 66% de FDN e 71,5% de DIVMS. O concentrado foi fornecido individualmente, na dose média de 6,6 kg de MN por vaca/dia com base na relação 1 kg de concentrado para cada 3 kg de leite, estabelecida no início do período experimental. O concentrado era idêntico entre os tratamentos, com exceção da inclusão ou não do éster análogo da metionina (HMBi). O delineamento experimental utilizado foi em crossover (2x2), dois tratamentos e dois períodos. Exceto os dados de contagem de células somáticas, os dados foram analisados pelo PROC MIXED (SAS® versão 9.1.3, 2003). Para os dados de células somáticas foi utilizada uma distribuição de Poisson, sendo analisados sob abordagem de modelos lineares generalizados. Não foram encontradas diferenças estatisticamente significativas para produção de leite (16,20 x 16,49), produção de leite corrigido para 3,50% de gordura (16,34 x 16,61), concentração de gordura no leite (3,57 x 3,57%) e concentração protéica no leite (3,12 x 3,13%), respectivamente para as vacas do grupo controle e as que receberam HMBi. Vacas ½ HPB ½ Jersey, apesar do menor peso corporal e menor consumo de concentrado, produziram leite com maior teor protéico que vacas HPB, e produziram a mesma quantidade de gordura e de proteína láctea. / In this trial, was tested the inclusion of isopropyl ester of methionine analogue (HMBi) in the concentrate of BWH cows and ½ BWH ½ Jersey cows kept in pastures of Elephant grass, with the goal of achieving lysine: methionine ratio of 3:1 in metabolizable protein. Variables analyzed were milk production and composition. The forage mass and the nutritional composition and morphology of the pasture were also evaluated. 16 Holstein cows and 12 ½ WBH ½ Jersey cows, with approximately 150 days in milk at the beginning of the trial period were used. The Elephant grass pasture was managed by rotational system with two days of occupation and variable rest period, determined by the sward height of 1m at the entry of animals in each paddock. The pasture was fertilized with 80 kg N per grazing cycle. The experimental cows were grazed in the first occupation day and extra animals of the herd grazed on the second occupation day of each paddock, ensuring the post grazing residue to be around 40 cm. The pasture contained on average 22% of CP, 66% of NDF and 71.5% of IVDDM. The concentrate was provided individually, the average dose of 6.6 kilograms of MN per cow per day, based on 1 kg of concentrate for every 3 kg of milk, established at the beginning of the trial period. The concentrate was similar among treatments, except for the inclusion or not of methionine ester analog (HMBi). The experimental design was a crossover (2x2), two treatments and two periods. Except the somatic cell count, the data were analyzed by the PROC MIXED (SAS ® version 9.1.3, 2003). For SCC data was used a Poisson distribution, and examined under approach of generalized linear models. There were no statistically significant differences in milk production (16.20 x 16.49), 3,50% fat corrected milk production (16.34 x 16.61), milk fat concentration (3.57 x 3.57%) and milk protein concentration (3.12 x 3.13%) respectively for cows from the control group and those receiving HMBi. Cows ½ BWH ½ Jersey, despite the lower body weight and lower concentrate intake, produced milk with higher protein content than cows BWH, and produced the same amount of milk fat and protein.

Through the Lens of a Frontline Worker: The Personal Reflections of a Health Education Specialist During the COVID-19 Pandemic

Herring, Danielle L. January 2024 (has links)
By the end of 2020, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), better known as COVID-19, had produced over 82,357,482 confirmed cases and 1,802,393 related deaths worldwide. The first pandemic many had ever experienced, the call of duty for public health professionals in the United States and globally was strong. While the contributions of doctors, nurses, and first responders are frequently acknowledged in the media and health-related publications, forgotten key players include health education specialists. Because of their critical role in public health preparedness and response, special attention should be given to their work during disasters and public health emergencies. As the Screening Manager of the New Jersey Department of Health (DOH) COVID-19 Testing Center located at Bergen Community College, I observed firsthand how COVID-19 made people suffer, but also the resilience among health education specialist responders. Using narrative inquiry to detail my response experience, this dissertation offers the world my story, while highlighting the onset of the pandemic in New Jersey from March to June 2020 and the practice of incorporating relevant health education competencies.
