Surface water is the greatest contributor to many water supplies in urbanized areas. Understanding local water sources and seasonality is important in evaluating water resource management, which is essential to ensure the sustainability of water supplies to provide potable water. Here we describe the municipal water cycle of Columbus, Ohio, USA, using δ18O, δD, and d-excess, and follow water from precipitation through surface reservoirs to a residential tap between May 2010 and November 2011. We show that trends in water isotopic composition of Ohio precipitation have a seasonal character with more negative values during the winter months and more positive values during the summer months. The year of 2011 was the wettest year on record in Central Ohio, with many months having high d-excess values (>+15‰), suggestive of increased moisture recycling, and possibly moisture introduced from more local sources. Tap waters experienced little lag time in the managed system, having a residence time of ~2 months in the reservoirs. Tap waters and reservoir waters preserved the isotopic signal of the precipitation, but the reservoir morphology also influenced the water residence time, and hence, the isotopic relationship to the precipitation. The reservoirs supplied by the Scioto River function like a river system with a fast throughput of water. The other reservoirs display more constant solute concentrations, longer flow-through times, and more lacustrine qualities. This work provides a basic understanding of a regional water supply system in Central Ohio and helps characterize the water flow in the system. These data will provide useful baseline information for the future as urban populations grow and the climate and hydrologic cycle changes.

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.

Attention in the literature has been given to the critical state of nursing leadership development. There is a need to identify effective ways to sustain and develop nursing leaders. Mentoring has been identified as an invaluable tool to attract and retain new nurse leaders. Examining the concept of mentoring in nursing leadership provides a greater understanding of its importance in today’s healthcare system. The concept of mentoring will be analyzed using the framework developed by Walker and Avant. A literature review was conducted to examine the current usage of the concept of mentoring. Consistent with Walker and Avant’s framework, defining attributes, antecedents, and consequences of mentoring have been identified. Further illustration of this concept is provided by describing model, borderline, related, and contrary cases. Demonstrating the occurrence of the concept of mentoring, Empirical referents will also be explored.

AIM:To analyze the accuracy of short-term bio-impedance as a means of measuring gastric ***: We evaluated differences in the short-term electrical bio-impedance signal from the gastric region in the following conditions: (1) fasting state, (2) after the administration of metoclopramide (a drug that induces an increase in gastric motility) and (3) after food ingestion in 23 healthy volunteers. We record-ed the real component of the electrical impedance signal from the gastric region for 1000 s. We performed a Fast Fourier Transform (FFT) on this data and then compared the signal among the fasting, medicated, and postprandial conditions using the median of the area under the curve, the relative area under the curve and the main peak ***: The median of the area under the curve of the frequency range in the region between 2-8 cycles per minute (cpm) decreased from 4.7 cpm in the fasting condition to 4.0 cpm in the medicated state (t=3.32, P=0.004). This concurred with the decrease seen in the relative area under the FFT curve in the region from 4 to 8 cpm from 38.3% to 26.6% (t=2.81, P=0.012) and the increase in area in the region from 2 to 4 cpm from 22.4% to 27.7%, respectively (t=-2.5, P=0.022). Finally the main peak position also decreased in the region from 2 to 8 cpm. Main peak activity in the fasting state was 4.72 cpm and declined to 3.45 cpm in the medicated state (t=2.47, P=0.025). There was a decrease from the fasting state to the postprandial state at 3.02 cpm (t=4.0, P=0.0013). CONCLUSION: Short-term electrical bio-impedance can assess gastric motility changes in individuals experiencing gastric stress by analyzing the area medians and relative areas under the FFT curve.

JOHNSON Key Laboratory of Western China's Environmental System of Ministry of Education College of Earth and Environmental Sciences Lanzhou University Lanzhou 730000 China Department of Geology and Geophysics University of Minnesota Minneapolis MN 55455 USA School of Geographical Sciences Southwest University Chongqing 400715 China Department of Earth System Science University of California Irvine CA 92697 USA

Based on 5 high-precision 230Th dates and 103 stable oxygen isotope ratios (δ18O) obtained from the top 16 mm of a stalagmite collected from Wanxiang Cave,Wudu,Gansu,variation of monsoonal precipita-tion in the modern Asian Monsoon (AM) marginal zone over the past 100 years was reconstructed. Comparison of the speleothem δ18O record with instrumental precipitation data at Wudu in the past 50 years indicates a high parallelism between the two curves,suggesting that the speleothem δ18O is a good proxy for the AM strength and associated precipitation,controlled by "amount effect" of the pre-cipitation. Variation of the monsoonal precipitation during the past 100 years can be divided into three stages,increasing from AD 1875 to 1900,then decreasing from AD 1901 to 1946,and increasing again thereafter. This variation is quite similar to that of the Drought/Flooding index archived from Chinese historical documents. This speleothem-derived AM record shows a close association with the Pacific Decadal Oscillation (PDO) between AD 1875 and 1977,with higher monsoonal precipitation corre-sponding to cold PDO phase and vice versa at decadal timescale. The monsoonal precipitation varia-tion is out of phase with the PDO after AD 1977,probably resulting from the decadal climate jump in the north Pacific occurring at around AD 1976/77. These results demonstrate a strong linkage between the AM and associated precipitation and the Pacific Ocean via ocean/atmosphere interaction. This rela-tionship will aid to forecast future hydrological cycle for the AM monsoon region,and to improve forecasting potential of climatic model with observation data from cave.
