NASA and the challenge of ISDN: The role of satellites in an ISDN world

To understand what role satellites may play in Integrated Services Digital Network (ISDN), it is necessary to understand the concept of ISDN, including key organizations involved, the current status of key standards recommendations, and domestic and international progress implementation of ISDN. Each of these areas are explained. A summary of the technical performance criteria for ISDN, current standards for satellites in ISDN, key players in the ISDN environment, and what steps can be taken to encourage application of satellites in ISDN are also covered

The Moderating Roles of Gender and Anti-Gay Prejudice in Explaining Stigma by Association in Male Dyads

Using a convenience sample of 157 undergraduates, this study explored the likeability ratings of target characters from selected film clips who were described as gay or heterosexual as they associated with a gay-described foil character (i.e., a character against which the target is compared). As predicted, male respondents who strongly endorsed anti-gay prejudice viewed gay-described targets more favorably than heterosexual-described targets when each target was paired with a gay foil. Further, this pattern of biased ratings by high-prejudice male participants against our heterosexual target differentiated these participants from both low-prejudice male and high-prejudice female respondents. In contrast, but as hypothesized, high-prejudice female respondents compared to high-prejudice males rated heterosexual-described targets more favorably than they rated gay-described targets

How your sexual orientation affects your salary in the UK

Research concerning labour market discrimination based on sexual orientation has yielded varying outcomes so far. Studies were usually based on small on unrepresentative samples. Drawing on a large and previously unavailable dataset, Cevat Giray Aksoy, Christopher S. Carpenter and Jefferson Frank find that gay men earn less than straight ones and heterosexual women earn less than lesbians

How your sexual orientation affects your salary

Research on the relationship between sexual orientation and labour market earning has relied either on surveys with small samples of sexual minorities, or has used large samples of same-sex couples, often with sample discrepancies. Drawing on a large individual-level dataset, Cevat Giray Aksoy, Christopher S. Carpenter and Jefferson Frank find that in the UK gay men earn less than straight ones and heterosexual women earn less than lesbians

Cafetería temática que promueva la gastronomía ancestral del pueblo pasto en la ciudad de Ibarra

Implementar una cafetería temática en la ciudad de Ibarra, provincia de Imbabura, orientada a impulsar la gastronomía ancestral del pueblo Pasto.El objetivo principal de este proyecto es llevar a cabo una investigación para crear una cafetería temática que contribuya a la revitalización del pueblo pasto, centrándose en la gastronomía, en la ciudad de Ibarra. Esta iniciativa tiene como propósito ofrecer oportunidades de empleo, así como proporcionar nuevos espacios saludables y gratuitos para los habitantes locales. El nombre del proyecto es "Cafetería Tradicional 04", y su misión es convertirse en un lugar donde los clientes puedan sumergirse en la riqueza cultural del pueblo pasto, a través de diversas imágenes, libros y revistas que cuenten sus mitos y leyendas. Además, la cafetería ofrecerá una amplia selección de alimentos y bebidas tradicionales, como humitas, empanadas de morocho, tamales, leche, jugo de caña, helados de paila, entre otros. Todo esto en un ambiente acogedor tanto para los turistas nacionales como extranjeros, con precios accesibles y un servicio de alta calidad. Con esta propuesta, buscamos brindar a los visitantes una experiencia única que promueva el conocimiento y aprecio por la cultura y la gastronomía del pueblo pasto. Asimismo, nuestro proyecto tiene el propósito de fomentar el desarrollo económico y social de la comunidad local, generando un impacto positivo en la región.LICENCIATUR

Evidence for a Climate-Driven Hydrologic Regime Shift in the Canadian Columbia Basin

Water resources from the Columbia River Basin are intensely used for domestic, agricultural, industrial and hydroelectric generation needs. Water availability in the Pacific Northwest is influenced by several ocean–atmosphere modes of climate variability that occur in the Pacific Ocean. Climate change has the potential to alter these relationships and influence both the volume and timing of streamflow in the snowmelt-dominated tributaries to the Columbia River. Here, the historical influences of climate variability and recent climate warming on the volume and timing of streamflow for 40 tributary streams in the Columbia River Basin of Canada were evaluated. Regional relationships were found between streamflow and several Pacific Ocean climate indices, including the already established relationships with the Pacific Decadal Oscillation (PDO) and El Nino/Southern Oscillation (ENSO). However, in recent decades the statistical relationship between streamflow and climate indices has become weaker, which has implications for managers using these indices as decision-making tools. A comparison of the average annual streamflow for the cool PDO phase, which occurred from 1947 to 1976, to the more recent cool phase from 1999 to 2011 indicates a 11% decline across the Canadian portion of the basin. Removing the influence of these climate indices on historical streamflow reveals decreases in the residual streamflow beginning sometime in the 1980s. The potential role of increased temperatures on streamflow was investigated, and statistically significant relationships between decreased streamflow and increased temperatures in the summer months were found, particularly with the number of days over 18°C. The results suggest that climate change may be altering the historical relationship between climate indices and streamflow in the Canadian portion of the Columbia Basin

Generating temperature cycle profiles of different solar photovoltaic module technologies from in-situ conditions for accurate prediction of thermomechanical degradation

The IEC61215 TC200 is a rigorous approval thermal cycling test process that assesses the reliability of solar photovoltaic modules and offers a 25-year lifetime guarantee. However, previous research has shown that installed solar photovoltaic modules experience different rates of degradation depending on the location and climate with most research focused on crystalline silicon. In this study, outdoor weathering data obtained from a rig set up in Kumasi, Ghana for the year 2014, is used to generate thermal cycles for 5 different technologies including monocrystalline, polycrystalline, and amorphous silicon, Copper Indium Gallium Selenide (CIGS) and Heterojunction-With-Intrinsic-Thin-Layer (HIT). From the results, the highest yearly average of the maximum and minimum temperatures, and ramp rates of 54.8oC, 26.1oC, and 6.05oC/h respectively are recorded in CIGS. Polycrystalline recorded the least temperatures of 45.2°C and 23.9°C while HIT recorded the least ramp rate of 4.45°C /h. A comparison between the 2014 and the IEC61215 thermal cycles show extremely wide differences which could explain the higher degradation rates and shorter life of installed solar photovoltaic modules. The procedure adopted in this research can be repeated at different locations to obtain technology-specific thermal cycling profiles to evaluate the thermomechanical damage and predict the life of different solar photovoltaic modules
