drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
adolescents and young adults and their problems is an issue whose importance is obvious to anyone because youth are the founders of our countrys future and requires proper planning to be on leisure. given the importance of leisure,this study to investigate needs assessment and planning how adolescents and young adults spend their leisure time in urban of case study of high school girls and boys...
Following a predicted decline in water resources in the Mediterranean Basin, we used reaction-diffusion equations to gain a better understanding of expected changes in properties of vegetation patterns that evolve along the rainfall transition between semi-arid and arid rainfall regions. Two types of scenarios were investigated: the first, a discrete scenario, where the potential consequences o...
Feeding 9-10 billion people by 2050 and preventing dangerous climate change are two of the greatest challenges facing humanity. Both challenges must be met while reducing the impact of land management on ecosystem services that deliver vital goods and services, and support human health and well-being. Few studies to date have considered the interactions between these challenges. In this study w...
Background and aims: Today, to improve workplace safety, more focus is on organizational and managerial factors including the organization climate and in particular the safety climate. Given that safety perception and attitudes of employees toward workplace safety situation is different in an organization so, for measuring these differences in the various conditions, including different job pos...
Climate change is one of the most serious challenges confronting agriculture, particularly, in rural Nigeria. This study examined the perception, adaptation strategies and challenges of climate change among rural households in Kogi State, Nigeria. A two stage sampling techniques was used in the study. The first stage involves the purposive selection of six (6) rural farming communities, followe...
daily discharge data of 12 hydrometric recording stations in atrak river basin were manipulated to calculate low flows for 7-day duration for studying hydrological drought using regional analysis method. using regression models, the low flows for 7-days duration of 10-year return period were calculated and regional low flows were estimated for 20 stations. daily data in each station used to sim...
Globally, efforts are underway to reduce anthropogenic greenhouse gas emissions and to adapt to climate change impacts at the local level. However, there is a poor understanding of the relationship between city strategies on climate change mitigation and adaptation and the relevant policies at national and European level. This paper describes a comparative study and evaluation of cross-national...
Increasing crop production at a time of rapid climate change represents the greatest challenge facing contemporary agricultural research. Our understanding of the genetic control of yield derives from controlled field experiments designed to minimize environmental variance. In spite of these efforts there is substantial residual variability among plants attributable to Genotype × Environment in...
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...
