A cluster sample survey was conducted in 1998 in 30 schools to assess the effect of the growth of Niamey during the last decade on a urinary schistosomiasis urban focus described in 1989. Two thousand and forty-two children (11.0 + 0.1 years old) had a urine filtration test and answered a behavioural questionnaire. Snail populations of the sites used by schoolchildren were followed up in 1999. ...

A two-year field study was conducted to investigate the performance of a lightweight trash-board moldboard plow (with and without a trash-board), as influenced by stubble height and water content. Both fields were measured for the performance of a trash-board moldboard plow when used during the optimization of the plowing depth, the water content, and the reaction forces. The results showed tha...

The high demand for cotton production worldwide has presented a need for its standardized classification. There currently exists trained classers and instrumentation to distinguish key cotton quality parameters, such as some trash types and content. However, it is of interest to develop a universal instrumental method with higher trash identification specificity. A program was implemented to de...

The study examined the hydraulic properties of IKPA river and its impact on sediment transport. Measurements such as depths river, Top width, discharges were measured along stretch river. cross section was divided with ranging poles maximum distance 4m apart. velocity 0.94m/s while minimum 0m/s recorded in cross-section rivers. at second vertical banks also bed regression analysis profile again...

Karkheh river is located in southwestern of Iran. Industrial and agricultural activities around the river contaminate it through its path. Water quality modeling from upstream of Shoosh city to downstream was simulated by QUAL2K model. In this study, we investigated how best to manage the quality of Karkheh river to be done. Nine parameters including BOD, COD, DO, PH, turbidity, nitrate, phosph...

Trash blankets contain substantial amounts of nitrogen (N) and other nutrients. The availability of N in trash is complicated because most of the N cycles through the soil organic matter. To gain insights into the long-term fate of N contained in trash, N dynamics in the SASEX long-term trash management experiment (BT1) were simulated with the APSIM-Sugarcane cropping systems model. Initially, ...

The laser Doppler flowmetry (LDF) technique provides the monitoring of microvascular blood flow perfusion. However, LDF monitors based on fiber-optic transducers have the serious drawback of generating TRAnsient Signal High-values (TRASH) in signals. These TRASH correspond to artifacts for clinicians as they prevent interpretations of the signal when they are numerous. Moreover, TRASH exclude t...

This research explored stereotypes associated with labels for White people: whites, white trash, and redneck. It also examined how these labels affect attitudes toward white subgroups. Participants described whites as dominant, elite, middleclass, and privileged. Rednecks and white trash were described with stereotypically negative characteristics, such as poor and uneducated. White trash were ...
