conclusions based on of this study, management has an important role in creating a positive safety climate. individual characteristics can influence thee safety climate. management commitment to safety is an important factor in the success of safety programs. results final scoring was done on a scale of one through ten. the highest scores were achieved in personal values (mean score, 8.7 ± 1.36...

because of low spatial resolution and simplifications in meteorological processes in global circulation models, they cannot sufficiently simulate the weather, comparing to the regional models; then, spatial and temporal downscaling of the gcm outputs are needed for decreasing errors of the global circulation models. there are two methods of downscaling: statistical and dynamic. weather generato...

■ Abstract Variability of the atmospheric and oceanic circulations in the earth system gives rise to an array of naturally occurring dynamical modes. Instead of being spatially independent or spatially uniform, climate variability in different parts of the globe is orchestrated by one or a combination of several climate modes, and global changes take place with a distinctive spatial pattern res...

Abstract Land degradation due to soil erosion presents a major challenge for sustainable development. We investigated run‐off and sediment yield (SY) dynamics in the northwestern highlands of Ethiopia. The study area included 14 zero‐order catchments with surface ranging from 324 1715 m 2 . V‐notch weirs produced plastic jars were introduced as measuring alternatives that met local constraints....

Bt cotton are plants that have been genetically modified to express the insecticidal proteins Cry 1 Ac from subspecies of the bacterium, Bacillus thuringiensis israelensis (Bt), to control bollworm pest that feed on cotton. There is a persistent environmental concern that transgenic Bt-crops carry genes that have indirect undesirable effect to natural and agro– ecosystem function. We investigat...

R apid population growth, coupled with economic expansion, is increasing the demands on land not only for agriculture but also for housing, infrastructure, recreation, and industry. Many of the agricultural regions in South and Southeast Asia characterized by intensive rice-or rice-wheat-based agroecosystems provide striking examples of conflicts in agricultural land-use objectives. The need fo...

The genus Oryctophileurus is reviewed and its validity is supported by a combination of the following apomorphic characters: a single cephalic horn with lateral carina, pronotal cavity with ocellate punctures and two teeth or tubercles close behind the anterior pronotal margin. The male of Oryctophileurus varicosus Prell, 1934, is described for the first time. A new species, Oryctophileurus gue...
