Estimation of genetic trends is necessary to monitor and evaluate selection programs. The objective of this study was to estimate the genetic trends for milk yield in Iranian Holsteins cows using random regression test day model. Data set was consisted of 743205 test-day records from 1991 to 2008, which were collected by the Animal Breeding Centre of Iran. Breeding, environmental and phenotypic...
BACKGROUND The Internet is an important tool to deliver health behavior interventions, yet little is known about Internet access and use of health-related information, or support, by the intended intervention recipients. OBJECTIVE Our aim was to evaluate whether health-related Internet use differed as a function of common health-risk behaviors (excessive alcohol consumption, smoking, low frui...
Blacks and Latinos are less likely than whites to access health insurance and utilize health care. One way to overcome some of these racial barriers to health equity may be through advances in technology that allow people to access and utilize health care in innovative ways. Yet, little research has focused on whether the racial gap that exists for health care utilization also exists for access...
Medical digital libraries can effectively provide clinical users with reputable, up-to-date information on which to base their clinical decision making processes. A study, within a large London-based hospital, of clinicians information perceptions and medical digital library usage patterns has identified 2 key usability issues which are impeding the successful implementation of these applicatio...
This article describes the uncertain future of the online catalog, and the tension that exists between creating a cataloging code that meets user needs while adhering to principles deemed important by the cataloging community. Underscoring this tension are the provocative questions posited by the Taiga Steering Committee, which call into question the future of libraries. For the traditional cat...
Little is known about access, sources, and trust of cancer-related information, or factors that facilitate or hinder communication on a population-wide basis. Through a careful developmental process involving extensive input from many individuals and organizations, the National Cancer Institute (NCI) developed the Health Information National Trends Survey (HINTS) to help fill this gap. This nat...
Due to global warming, and its resulting changes in the frequency and amount of precipitation and temperature, there has been a great concern on climate change impacts by the scientific community. This study focuses on trend analysis of annual and seasonal rainfall (P), maximum temperature (Tmax) and minimum temperature (Tmin) time series from seven meteorological stations in Gorgranrood rive...
When my co-founders and I began BookSurge in 2000, it was an excellent time to dive into the publishing world, especially if you knew nothing about it. We had no previous publishing industry experience that would inform our view of how the company would operate. In this mindset, we asked ourselves: Why not be a publisher, printer, and retailer all at once? The slate was totally clean. I view Bi...
The present monograph studies the asymptotic behaviour of eigenvalues, products and functions of block Toeplitz matrices generated by the Fourier coefficients of a continuous matrix-valued function. This study is based on the concept of asymptotically equivalent sequences of non-square matrices. The asymptotic results on block Toeplitz matrices obtained are applied to vector asymptotically wide...
evaluation of river discharges trends is very important for water resources management and design of irrigation and drainage networks. in this research, annual, seasonal and monthly trends of maroon river discharge were evaluated using the mann-kendall and senâs slope estimator non-parametric tests and the regression analysis parametric test. for this purpose, river discharge data from five h...
