Tendencias actuales en los algodones de planchado permanente.

La introducción en 1964 de prendas de planchado permanente en Estados Unidos tuvo un impacto que puede compararse por su importancia con el de la introducción del nylon. El empleo de tejidos de algodón 100 % para planchado permanente ha disminuído debido a un problema de abrasión debido principalmente a las duras condiciones del tratamiento químico. Se describen métodos que aumentan la resistencia a la abrasión de los tejidos de algodón 100 %. Estos métodos incluyen la adición de determinados polímeros y suavizantes, mercerizado sin tensión del tejido antes de la reticulación, y el empleo de adecuadas condiciones de polimerización así como de un hilo o tejidos de alta resistencia. Igualmente, se describen otros métodos tales como reticulado optativo, doble polimerización y fijado en húmedo. En todos estos procesos la elección adecuada del agente reticulador es muy importante. Estos resultados demuestran que pueden producirse mejores algodones 100% para planchado permanente mediante cierto número de procesos nuevos.Peer Reviewe

El acabado de los tejidos elásticos de algodon.

Los tejidos elásticos de algodón fabricados mediante mercerizado sin tensión de tejidos de calada y acabados utilizando agentes de reticulado, proporcionan a la prenda y a los mercados industriales una mercancía muy útil cuyos usos aumentan cada día gracias a la investigación aplicada. La construcción de un tejido es más importante que las variaciones de la estructura del hilo. Se han observado algunas diferencias al estabilizar las propiedades elásticas en un estudio limitado de diversos agentes de reticulado. Sin embargo, se considera que las condiciones adecuadas de reticulado son más importantes que el tipo de agente de reticulado. En la aplicación de múltiples acabados no se observaron diferencias significantes en las propiedades como consecuencia del tipo de colorante aplicado, mientras que la elección de un suavizante fue de importancia. Igualmente, algunos tratamientos ignífugos que utilizan THPC han coadyuvado a estabilizar los tejidos mercerizados sin tensión, sin reducir las propiedades elásticas. Se detallan distintos productos comerciales y se describe su método de producción. Se pueden producir encajes labrados con propiedades elásticas mediante un proceso simple. La forma de someter a proceso a los tejidos de algodón elástico pudiera incluir una variación del proceso de planchado permanente; por tanto, se necesitan nuevas mejoras y una mayor investigación para conseguir que los tejidos y prendas respondan al último requerimiento de comodidad y fácil cuidado.Peer Reviewe

Fish choose appropriately when and with whom to collaborate

SummaryCollaborative abilities are integral to human society [1] and their evolutionary origins are of great interest. Chimpanzees are capable of determining appropriately when and with whom to collaborate in a rope-pull experiment [2] — the only non-human species known to possess both abilities. Chimpanzees are thought to share these abilities with humans as a result of common ancestry [2]. Here, we show that a fish — the coral trout Plectropomus leopardus — has partner-choice abilities comparable to those of chimpanzees in the context of its collaborative hunting relationship with moray eels [3]. Using experiments analogous to those performed on chimpanzees [2], but modified to be ecologically relevant to trout, we showed that trout recruit a moray collaborator more often when the situation requires it and quickly learn to choose the more effective individual collaborator. Thus, these collaborative abilities are not specific to apes and may be more closely linked to ecological need [4] than brain size or relatedness to humans

Self-Regulatory Profile Scale: Development and initial psychometric validation using Exploratory Structural Equation Modeling (ESEM)

Doctor of PhilosophySchool of Family Studies and Human ServicesMajor Professor Not ListedThe ability to regulate oneself, and the consequences of under-regulation, have long been an area of inquiry for many disciplines. Various domains of self-regulation have historically been studied independent of one another, despite the interactive nature and interdependent development of the domains. Currently, no quantitative measure exists that evaluates the whole of the self-regulatory system. This study seeks to confirm a factor structure of six domains of self-regulation, as proposed by the Self-Regulation Model of Attachment Trauma and Addiction (Padykula & Conklin, 2010) using exploratory structural equation modeling (ESEM). A psychometric validation of the measure was completed in two cross-sectional studies. In study 3, the measure was externally validated against a nomological network of related constructs. ESEM confirmed the use of the six pillar, 12 facet model to examine a profile of self-regulation. Clinical and research implications of the findings are discussed

Cenozoic paleoceanography 1986: An introduction

New developments in Cenozoic paleoceanography include the application of climate models and atmospheric general circulation models to questions of climate reconstruction, the refinement of conceptual models for interpretation of the carbon isotope record in terms of carbon mass balance, paleocirculation, paleoproductivity, and the regional mapping of paleoceanographic events by acoustic stratigraphy. Sea level change emerges as a master variable to which changes in the ocean environment must be traced in many cases, and tests of the onlap-offlap paradigm therefore are of crucial importance

How doctors' communication style and race concordance influence African-Caribbean patients when disclosing depression

Objective: To determine the impact of doctors' communication style and doctor-patient race concordance on UK African-Caribbeans' comfort in disclosing depression. Methods: 160 African-Caribbean and 160 white British subjects, stratified by gender and history of depression, participated in simulated depression consultations with video-recorded doctors. Doctors were stratified by black or white race, gender and a high (HPC) or low patient-centred (LPC) communication style, giving a full 2. ×. 2. ×. 2 factorial design. Afterwards, participants rated aspects of doctors' communication style, their comfort in disclosing depression and treatment preferences. Results: Race concordance had no impact on African-Caribbeans' comfort in disclosing depression. However a HPC versus LPC communication style made them significantly more positive about their interactions with doctors (p = 0.000), their overall comfort (p = 0.003), their comfort in disclosing their emotional state (p = 0.001), and about considering talking therapy (p = 0.01); but less positive about considering antidepressant medication (p =0.01). Conclusion: Doctors' communication style was shown to be more important than patient race or race concordance in influencing African Caribbeans' depression consultation experiences. Changing doctors' communication style may help reduce disparities in depression care. Practice Implications: Practitioners should cultivate a HPC style to make African-Caribbeans more comfortable when disclosing depression, so that it is less likely to be missed
