The coronal slow shock has been changes of alpha particles' velocity, density, and predicted to exist embedded in large coronal holes temperature have been published, both for fast at 4-10 solar radii. We use a three-fluid model to interplanetary shocks and for the Earth's bow study the jumps in minor ion properties across a slow shock such as the coronal slow shock. We formulate the jump condi...

Tall fescue (Festuca arundinacea Schreb.) is the most commonly used cultivated grass in the United States to feed beef cattle. Tall fescue is a cool-season perennial grass that many cattle producers ‘can’t live with, but can’t live without’ because of its hardiness and good forage yields, but adverse effects on cattle well-being and yields. The history of this forage and its effects on animal p...

have elevated levels of thyroid hormones (Barron, 1986; Hoar, 1988; Datta et al., 1999; Eales, 1990). Thyroid hormones play a central role in controlling many of the alterations in physiology, morphology and behavior noted during this metamorphic transition in juvenile salmon (Hoar, 1988). Thyroid hormones have also been identified in altering the visual system during smoltification. During mig...

This paper attempts to investigate the theoretical underpinnings for the reasons why firms frequently adopt the dual class equity structure, i.e. a capital (or ownership) structure based on the issuance of shares with differential voting rights (DeAngelo et al. 1985). Such an ownership structure is justified by some researchers as a defensive structure adopted by the directors and managers of a...

We have identified a family of abundant peripheral plasma membrane glycoproteins that is unique to flowering plants. They are identified by a monoclonal antibody, MAC 207, that recognizes an epitope containing L-arabinose and o-glucuronic acid. Immunofluorescence and immunogold labeling studies locate the MAC 207 epitope to the outer surface of the plasma membrane both in protoplasts and in int...

Soil organic C content, a major source of system stability in agroecosystems, is controlled by many factors that have complex interactions. The purpose of this study was to evaluate the major controls over soil organic carbon content, and to predict regional patterns of carbon in range and cultivated soils. We obtained pedon and climate data for 500 rangeland and 300 cultivated soils in the U.S...

Nested logit is increasingly advocated as a tool of recreational demand and benefit estimation. The intent of this short monograph is to lay out, in a simple fashion, the theory behind the nested-logit model of site choice and the nested-logit model of participation and site choice. Rigorous but straightforward derivations of the properties of nested-logit models are provided, including the pro...

Urinary tract infections (UTIs) are one of the most common infectious diseases (Kolawale et al., 2009; Delanghe et al., 2000; Hryniewicz et al., 2000). They may be symptomatic or asymptomatic, and either type of infection can result in serious sequelae if not appropriately treated (Pezzlo, 1988). Although different causative agents can be responsible for UTIs, bacteria are the major cause being...

بیش از سه دهه است که پژوهشگران سعی می کنند قطعات الکترونیکی با اندازه کوچکتر و کارایی هرچه بیشتر تولید کنند. در 20 سال اخیر کوشش های زیادی برای درک خواص رسانش الکترونی پلیمرهای همیوغ-? بعمل آمده است. این سیستم های نیمه رسانا نقش مهمی در طراحی سیستم های مولکولی برای کاربردهای الکترونیکی دارند. سیم های مولکولی واحدهای ساختاری بنیادی در طراحی قطعات الکترونیکی مولکولی هستند. یک سیم مولکولی شامل یک ...
