An extensive literature on climate change modeling points to future changes in wind climates. Some areas are projected to gain wind resources, while others are projected to lose wind resources. Oklahoma is presently wind rich with this resource extensively exploited for power generation. Our work examined the wind power implications under the IPCC’s A2 scenario for the decades 2040–2049, 2050–2...
BackgroundInfections caused by non-cholera Vibrio species have undergone a global expansion over the past few decades reaching new areas of world that were previously considered adverse for these organisms. The geographical extent has not been uniform, and some shown rapid increase in infections.MethodsWe applied generation models combining climate, population, socioeconomic projections to map ...
statistical modeling of future lake level under climatic conditions, case study of urmia lake (iran)
the present research focuses on the changes of urmia lake level. for this purpose, two timescales have been considered. the trend changes of temperature, precipitation rate and quantitative values of climate type for the observational period from 1968 to 2011 (past scale) and from 2011 to 2100 (future scale) have been analyzed. general circulation model (gcm) is considered for simulating the va...
power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
abstract the current study set out to address the issue as to whether the implementation of portfolio assessment would give rise to iranian pre-intermediate efl learner autonomy. participants comprised 60 female in pre-intermediate level within the age range of 16-28.they were selected from among 90 language learners based on their scores on language proficiency test -key english test. then, t...
in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
Hopefully there will be no war in 2050 or at any time in the future. But if the past is prologue, humankind’s warlike history compels a nation to think about and prepare for the challenges posed by a future conflict. To the extent we can predict, the bets are that the remarkable surge of information technologies of the last few decades will continue, even accelerate. Included in this set of tec...
Climate change is likely to manifest in river flow changes across the globe, which could have wide-ranging consequences for society and natural environment. A number of previous studies used UK Projections 2009 (UKCP09) investigate potential impacts on flows Britain, but these projections were recently updated by release UKCP18, thus there a need update studies. Here, UKCP18 Regional (12 km) ar...
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
Over the last 50 years, the use of nitrogen (N) and phosphorus (P) fertilizers has increased at a faster rate than global food production, resulting in substantial decreases of N and P efficiency in agriculture (Fig. 1). Thus, considerable amounts of N and P fertilizers have beenwasted in agroecosystems, and the alteration of N and P biogeochemical cycles is among the most visible impacts of hu...
