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

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
