A study was carried out to identify and estimate the prevalence of ecto- and endoparasites of village chicken between April and July 2008 in three local councils of Enugu state, Nigeria. A total of 1038 chickens comprising of 468 chicks, 207 growers and 363 adults were examined during the house to house survey for ectoparasites, gastrointestinal helminths and coccidia infections. Our finding sh...

The availability of water in Chile has shown signs decline recent decades. This is problematic because Chile’s economy depends on mining, forestry, and agricultural activities, all limited by the resources. In this study, daily, monthly annual flows 31 basins located arid–semiarid zones (29°12′ S–33°58′ S) humid–subhumid (34°43′ S–38°30′ were evaluated using Mann–Kendall trend test quantile–Ken...

Climate variability has profound effects on vegetation. Spatial distributions of vegetation vulnerability that comprehensively consider sensitivity and resilience are not well understood in China. Furthermore, the combination cumulative climate a one-month-lagged autoregressive model represents an advance technical approach for calculating sensitivity. In this study, spatiotemporal characterist...

A regional regression model was developed to estimate the spatial distribution of ground water recharge in subhumid regions. The regional regression recharge (RRR) model was based on a regression of basin-wide estimates of recharge from surface water drainage basins, precipitation, growing degree days (GDD), and average basin specific yield (SY). Decadal average recharge, precipitation, and GDD...

Shrubs tended to increase their abundance as climatic aridity and grazing intensity increased in the Inner Mongolian grassland. Increasing shrub was believed be due enhanced reproduction. However, effects of on sexual reproduction shrubs grassland remain largely unclear. In this study, we conducted field experiments with Caragana microphylla examine variation aspects (seed production, seed vigo...

Landfill covers are critical to waste containment, yet field performance of specific cover designs has not been well documented and seldom been compared in side-by-side testing. A study was conducted to assess the ability of landfill final covers to control percolation into underlying waste. Conventional covers employing resistive barriers as well as alternative covers relying on water-storage ...

The Mollisols from the Pampas Region of Argentina have been described as presenting different compactability behaviors under agricultural systems. The purpose of this study was to provide information on the inherent soil factors related to the susceptibility to compaction. Total organic carbon (TOC), texture (CLAY, SILT, SAND), water retention at 0.33 kPa (WR), Proctor maximum bulk density (BDM...

The main problems of stratigraphic taxonomy and no menclature Paleoproterozoic metamorphic formations the Ukrainian Shield are characterized by example Kryvyi Rih (Kryvyi Rih-Kremenchuk), Ingulets (W-Ingulets) Ingul structural-formation zones. In addition to existing units regional rank — series relevance identifying supra-regional tectono-stratigraphic structural-material complexes, which have...
