population growth can greatly impact on greenhouse gas emission pattern in the future. considering the importance of population growth in climate change studies, the present research concentrates on the population growth of the middle east in the late 21th century based on the iiasa population scenarios. under the projections of a1-b1 scenario, the world’s population will grow up to 8.7 billion...
Increased demand for cooling and decreased demand for heating in the built environment is one of the main anticipated modes of adaptation to higher temperatures due to climate change. California’s residential sector uses relatively little electricity for heating. It is therefore expected that the demand for electricity will increase at the intensive margin as households operate existing air con...
this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
after the soviet union dissolution, a chaotic period was begun in the russia. russia lost its glory and felt disgrace. the first group of elites came to power under yeltsin; they tried to re-define russia’s identity as a european country and build a foreign policy on this baseline. therefore russia tried to become closer with the west especially with the u.s. according to their view the sovie...
Water resource management is becoming increasingly challenging in northern China because of the rapid increase in water demand and decline in water supply due to climate change. We provide a case study demonstrating the importance of integrated watershed management in sustaining water resources in Chifeng City, northern China. We examine the consequences of various climate change scenarios and ...
Coal was central to the industrial revolution, but in the 20th century it increasingly was superseded by oil and gas. However, in recent years coal again has become the predominant source of global carbon emissions. We show that this trend of rapidly increasing coal-based emissions is not restricted to a few individual countries such as China. Rather, we are witnessing a global renaissance of c...
چکیده قاجارها و حکومت پهلوی اول علی بازوند موضوع انقراض سلسله قاجار و انتقال حکومت به پهلوی از رخدادهای مهم تاریخ معاصر ایران است . که در این پژوهش به چگونگی نقش و عملکرد دیوان سالاران ، شاهزادگان و رجال خاندان قاجاری در این انتقال قدرت و نحوه ی برخورد رضاشاه با قاجارها دردوران سلطنت به آن پرداخته شده است . برای پاسخ به این مسأله ، بررسی های انجام گرفته بیانگر آن است که مخالفت افراد قاج...
Fluxes of CO2, water vapor, and sensible heat were measured by the eddy covariance method above a young ponderosa pine plantation in the Sierra Nevada Mountains (CA) over two growing seasons (1 June–10 September 1997 and 1 May–30 October 1998). The Mediterranean-type climate of California is characterized by a protracted summer drought, with precipitation occurring mainly from October through M...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
The United Nations Conference on Climate Change (Paris 2015) reached an international agreement to keep the rise in global average temperature 'well below 2°C' and to 'aim to limit the increase to 1.5°C'. These reductions will have to be made in the face of rising global energy demand. Here a thoroughly validated dynamic econometric model (Eq 1) is used to forecast global energy demand growth (...
