Peak oil” refers to the future decline in world production of crude oil and to the accompanying potentially calamitous effects. The peak oil literature typically rejects economic analysis. This chapter, following Holland (2008), argues that economic analysis is indeed appropriate for analyzing oil scarcity since standard economic models can replicate the observed peaks in oil production. Moreov...
BACKGROUND Previous research has documented effects of both physical and social environmental exposures on childhood asthma. However, few studies have considered how these two environments might interact to affect asthma. OBJECTIVE This study aimed to test interactions between chronic exposure to traffic-related air pollution and chronic family stress in predicting biologic and clinical outco...
Andes virus (ANDV) causes hantavirus pulmonary syndrome (HPS), a severe acute disease with a 40% case fatality rate. Humans are infected via inhalation, and the lungs are severely affected during HPS, but little is known regarding the effects of ANDV-infection of the lung. Using a 3-dimensional air-exposed organotypic human lung tissue model, we analyzed progeny virus production and cytokine-re...
Spent layers of 128 weeks age from a White Leghorn (Babcock) layer tlock were induced to molt by withdrawal of feed for 14 days. The birds lost approximately 29.64% of their body weight. The blood samples were collected at pre-molt, post-molt and peak production stages. Maximum concentrations of cholesterol and glucose were observed at pre-molt and minimum at post-molt stage. Urea, protein and ...
تمرینات plyometric در سال 1975 توسط آقای wilt توضیح داده شده، ولی تاکنون اثر این تمرینات بر عملکرد عضلات مورد مطالعه قرار نگرفته است . لذا هدف از این مطالعه، بررسی اثر این تمرینات بر عملکرد عضله چهارسر رانی می باشد. نمونه مورد مطالعه 15 نفر از دانش آموزان 18-16 ساله یکی از دبیرستانهای پسرانه تهران می باشند که پس از انجام پیش تست های مشخص برای این آزمایش در نظر گرفته شدند و فاکتورهای peak torque...
Electricity consumption has been rising with an average annual growth of 7% in Iran and the imbalance in production and consumption has caused power outage crisis and economic losses. More than 50% of peak electricity demand is related to the household sector, so the household sector can be considered as the most effective component of the electricity crisis. Investment costs for the constructi...
Demand-side management is one of the ways to create interaction between the microgrid and increase consumer participation in management schemes. Different algorithms and strategies have been used to execute consumption management programs that often covering a limited number of loads in several specific types. In this paper, first, the load shift method as an optimization problem to reduce syst...
Nonadherent spleen cells of mice infected with Trichinella spiralis released growth stimulatory factors (GSFs) in vitro when challenged with excretory/secretory products of muscle stage larvae. The assay of GSF was based on proliferation of normal, nonadherent syngeneic marrow cells in liquid tube cultures. Media conditioned for 1 day by challenged spleen cells stimulated eosinophil production ...
Ethylene production by tissue slices from preclimacteric, climacteric, and postclimacteric apples was significantly reduced by isopentenyl adenosine (IPA), and by mixtures of IPA and indoleacetic acid, and of IPA, indoleacetic acid, and gibberellic acid after 4 hours of incubation. Ethylene production by apple (Pyrus malus L.) slices in abscisic acid was increased in preclimacteric tissues, dec...
