Green Apparel Consumption: An Empirical Examination of Behavior versus Attitudes

The research reports empirical findings that contrast apparel consumers who behave in pro-environment purchasing behavior with those who do behave in pro-environmental purchasing behavior, in an effort to better understand the attitude-behavior gap commonly recognized among consumer researchers in the ethical consumption research stream. A large cross-section of U.S. Consumer data (N=1,846) provides the sample data for analyses.Demographics, product preferences, attribution behavior and intentions are contrasted between the two groups using appropriate statistical tests. Distinctly different profiles of the two consumer groups emerge, suggesting a number of directions for future research with academic and practical implications

Adjuvant treatment for older women with invasive breast cancer

Older women experience a large share of breast cancer incidence and death. With the projected rise in the number of older cancer patients, adjuvant chemo-, radiation and endocrine therapy management will become a key component of breast cancer treatment in older women. Many factors influence adjuvant treatment decisions including patient preferences, life expectancy and tumor biology. Geriatric assessment predicts important outcomes, identifies key deficits, and can aid in the decision making process. This review utilizes clinical vignettes to illustrate core principles in adjuvant management of breast cancer in older women and suggests an approach incorporating life expectancy and geriatric assessment

Glass Transition Behavior of Polymer Films of Nanoscopic Dimensions

Glass transition behavior of nanoscopically thin polymer films is investigated by means of molecular dynamics simulations. A thin polymer film that is composed of bead-spring model chains and supported on an idealized, fcc lattice substrate surface is studied in this work.Comment: in review, macromolecule

One-Dimensional Nanostructures and Devices of II–V Group Semiconductors

The II–V group semiconductors, with narrow band gaps, are important materials with many applications in infrared detectors, lasers, solar cells, ultrasonic multipliers, and Hall generators. Since the first report on trumpet-like Zn3P2nanowires, one-dimensional (1-D) nanostructures of II–V group semiconductors have attracted great research attention recently because these special 1-D nanostructures may find applications in fabricating new electronic and optoelectronic nanoscale devices. This article covers the 1-D II–V semiconducting nanostructures that have been synthesized till now, focusing on nanotubes, nanowires, nanobelts, and special nanostructures like heterostructured nanowires. Novel electronic and optoelectronic devices built on 1-D II–V semiconducting nanostructures will also be discussed, which include metal–insulator-semiconductor field-effect transistors, metal-semiconductor field-effect transistors, andp–nheterojunction photodiode. We intent to provide the readers a brief account of these exciting research activities

Colostrum pasteurization: Effect on bacterial count and immunoglobulin G concentration

La pasteurización de calostro a nivel de finca ha recibido una considerable atención en los últimos años, con el fin de reducir agentes patógenos bacterianos. La adopción de esta práctica a nivel de finca ha reportado resultados significativos en la salud de las terneras y en los ingresos económicos de los productores. Sin embargo, existe poca información con respecto al efecto que tiene la pasteurización sobre la concentración de inmunoglobulinas G (IgG). Por esta razón, se llevó a cabo una investigación con el objetivo de determinar el efecto de la pasteurización (baja temperatura-largo tiempo) sobre el nivel bacterial y la concentración de IgG en calostro bovino. Se colectó calostro de primer ordeño de 28 vacas Holstein. Cada muestra se agitó completamente y dos sub-muestras de 10- mL fueron analizadas. La primera sub-muestra sirvió como control mientras que la segunda fue calentada a 62.8 °C por 30 min. Las muestras de calostro tratadas y sin tratar fueron analizadas para determinar el conteo estándar de placa (CEP), conteo preliminar de incubación (CPI), conteo de coliformes (CC), conteo de no-coliformes (CNC), conteo de estreptococos ambientales (CEA) y conteo de Staphylococcus aureus (CSA). Las concentraciones de IgG1 e IgG2 fueron medidas utilizando la técnica de inmunodifusión radial. Los resultados del estudio mostraron que la pasteurización tuvo como resultado una reducción significativa (P < 0.01) en los niveles de CEP, CC, CNC, CEA y CSA. La pasteurización tuvo también como resultado la desnaturalización del 14% de las IgG totales en el calostro.On-farm pasteurization of colostrum has received considerable attention in recent years, primarily to reduce bacterial pathogens. Application of this practice has been reported to result in significant health benefits for calves and economic returns for producers. However, little information is available on the effect of pasteurization on immunoglobulin G (IgG) concentration. A research study was conducted with the objective to determine the effect of low temperature-long time pasteurization on the bacteriology and IgG concentration in bovine colostrum. First milking colostrum was collected from 28 Holstein cows. Each sample was thoroughly mixed and two 10-mL aliquots were analyzed. The first aliquot served as the control while the second aliquot was heated for at 62.8 °C 30 min. The treated and untreated colostrum samples were examined for standard plate count (SPC), preliminary incubation count (PIC), coagulase-negative staphylococci (CNS) count, environmental streptococci (ES) count, coliform (CC) count, gram-negative noncoliform (NC) count, Streptococcus agalactiae (SAG) count, and Staphylococcus aureus (SA) count. Colostrum IgG1 and IgG2 concentrations were measured using radial immunodiffusion. The results of the study showed that pasteurization resulted in a significant (P < 0.01) reduction of SPC, CC, NC, ES, CNS, and SA. Pasteurization also resulted in denaturation of 14% of colostral total IgG.UCR::Vicerrectoría de Investigación::Unidades de Investigación::Ciencias Agroalimentarias::Estación Experimental de Ganado Lechero Alfredo Volio Mata (EEAVM

Electronically induced modification of thin layers on surfaces

Interactions of thermally and electronically stimulated reactions in thin layers on surfaces are investigated. For self-assembled monolayers, thermal activation promotes many processes primarily induced by electronic excitations. We demonstrate that the film temperature is an important parameter for steering these reactions towards different final products. Using chemisorbed water on Ru(001) as an example, we investigate how the products of an irradiation induced reaction catalyze thermally stimulated dissociation of water molecules

Not AvailableThis study assessed and compared the genetic diversity of Nemipterus randalli across its native and non-native regions analysing the mitochondrial DNA D-loop region. Including all the geographical population samples, 68 haplotypes were observed with an average haplotype diversity value of 0.92±0.04. Relatively, a smaller number of haplotypes was observed in the invasive range of the Mediterranean Sea. All other native geographical samples showed high haplotype and nucleotide diversity values. A significant high genetic differentiation value was observed between the native population samples of India and the invasive samples of the Mediterranean Sea. In the median-joining network tree, N. randalli from the Mediterranean Sea and the Red Sea formed a single haplogroup while other samples from India are clustered into two haplogroups.Not Availabl
