AIM To investigate hepatitis C virus(HCV) testing recommendations from the United States and other high-income *** A comprehensive search for current HCV testing recommendations from the top quartile of United Nations Human Development Index(HDI) countries(very high HDI) was performed using Google and reviewed from May 1-October 30, 2014 and re-reviewed April 1-October 2, 2017. RESULTS Of the 51 countries identified, 16 had HCV testing recom-mendations from a government body or recommendations issued collaboratively between a government and a medical organization. Of these 16 countries, 15 had HCV testing recommendations that were primarily risk-based and highlight behaviors, exposures, and conditions that are associated with HCV transmission in that region. In addition to risk-based testing, the HCV Guidance Panel(United States) incorporates recommendations for aone-time test for individuals born during 1945-1965(the birth cohort) without prior ascertainment of risk into their guidance. In addition to the United States, six other countries either have an age-based testing recommendation or recommend one-time testing for all adults independent of risk factors typical of the region. CONCLUSION This review affirmed the similarities of the HCV Guidance Panel's guidance with those of recommendations from very high HDI countries.

ZnSe Nanoparticles were synthesized by solvothermal method and the particle was characterized by Transmission Electron Microscopy. The polymer nanocomposite of 2% and 4% ZnSe/EVA was fabricated by direct sonicator method. The nanocomposites were characterized by UV-Vis-NIR and FT-IR spectroscopy. The thermal behaviour of the samples was also investigated and we found that the thermal stability of the composites increased with increasing the filler concentrations. The mechanical properties such as tensile strength, peel strength and refractive index of the samples were also studied and reported for the first.

Accurate models to simulate the soil water balance in semiarid cropping systems are needed to evaluate management practices for soil and water conservation in both irrigated and dryland production systems. The obj.ctive of this study was to evaluate the application of the Precision Agricultural Landscape Modeling System (PALMS) model to simulate soil water content throughout the growing season for several years and for three maj.r soil series of the semiarid Texas Southern High Plains (SHP). Accuracy of the model was evaluated by comparing measured and calculated values of soil water content and using root mean squared difference (RMSD), squared bias (SB), squared difference between standard deviations (SDSD), and lack of correlation weighted by the standard deviation (LCS). Different versions of the model were obtained by modifying soil hydraulic properties, including saturated hydraulic conductivity (Ks) and residual (θr) and saturated (θs) soil volumetric water content, which were calculated using Rosetta pedotransfer functions. These modifications were combined with updated routines of the soil water solver in PALMS to account for rapid infiltration into dry soils that often occur in the SHP. Field studies were conducted across a wide range of soil and water conditions in the SHP. Soil water content was measured by neutron attenuation and gravimetrically throughout the growing seasons at each location to compare absolute values and the spatial distribution of soil water with PALMS calculated values. Use of Rosetta calculated soil hydraulic properties improved PALMS soil water calculation from 1% - 13% of measured soil volumetric water content (θv) depending on soil type. Large-scale models such as PALMS have the potential to more realistically represent management effects on soil water availability in agricultural fields. Improvements in PALMS soil water calculations indicated that the model may be useful to assess long-term implications of management practices
