In a double-blind clinical trial, 114 subfertile men were given courses of clomiphene citrate (100 mg daily for three 10-day periods in successive months) and ofplacebo tablets of identical appearance. There were no consistent changes in sperm density. No serious adverse reactions to clomiphene were seen. Further studies are recommended on the efficacy of clomiphene in doses of 25 to 50 mg dail...

introduction selection of the clear and transparent index for the precipitation using long-term homogeneous data is an important point for the researchers. several investigations have led to different indices for heavy rainfall. in some cases the specific amount of precipitation was used for heavy rainfall (rahimzadeh, 2005; masoodian, 2008; kamiguchi et al., 2006), e.g. alijani (2002) has sugg...

Hertz, A., Finding a feasible course schedule using Tabu search, Discrete Applied Mathematics 35 (1992) 255-270. We consider a course scheduling problem in which the total number of time periods assigned to each topic has to be split into daily amounts of consecutive time periods called daily quantums. These daily quantums may be arbitrary but are bounded by given minimal and maximal values. In...

gully erosion is one of the most destructive types of channeled water erosion that removes aconsiderable volume of soil as it develops. this type of erosion consists of complex a geomorphicprocess that has been known as an indicator of accelerated soil erosion. in this research theadvancement of 25 headcuts were assessed through digital interpretation of multi-temporal aerialphotos, field obser...

background: work-related musculoskeletal disorders (wmsds) have been documented among various occupational groups in nigeria. however, there is limited data on the prevalence of wmsds among call center operators (ccos). objective: to determine the prevalence of wmsds among ccos in nigeria and to explore the extent to which these discomforts impact the daily work activities of the respondents. m...

OBJECTIVE We hypothesized that a daily rounding checklist and a computerized order entry (CPOE) rule that limited the scheduling of complete blood cell counts and chemistry and coagulation panels to a 24-hour interval would reduce laboratory utilization and associated costs. METHODS We performed a retrospective analysis of these initiatives in a pediatric cardiovascular ICU (CVICU) that inclu...

Daily and monthly flow-rates of the Little Nemaha River in Nebraska were simulated by the lumped-parameter Jakeman-Hornberger as well as a distributed-parameter water-balance accounting procedure for the 2003-2008 and 20002009 periods, respectively, with and without the help of the MODIS-based monthly estimates of evapotranspiration (ET) rates. While the daily lumped-parameter model simulation ...
