اکوسیستم مرتعی از قطعات متنوعی تشکیل شده است که میزان عملکرد هر یک از آنها به یکدیگر تفاوت می کند. شناخت کارکرد یک اکوسیستم طبیعی نیاز به آگاهی از مشخصه ها و معرف های خاکی و گیاهی دارد که بتوان به توانمندی و پتانسیل آن اکوسیستم پی برد. بررسی روابط بین پوشش گیاهی و خاک کمک شایانی به شناخت پتانسیل ها و عملکرد مراتع خواهد داشت. این بررسی، با استفاده از روش تجزیه و تحلیل کارکرد اکوسیستم طبیعی (lfa)...

UNLABELLED Previous work has provided evidence for a brief, finite ( approximately 35 ms) temporal window of integration (TWI) in M100 formation, during which stimulus attributes are accumulated in processes leading to the M100 peak. Here, we investigate resolution within the TWI by recording responses to tones containing silent gaps (0-20 ms). Gaps were inserted in 1 kHz tones in 2 conditions:...

BACKGROUND Inadequate hydration is a public health issue that imposes a significant economic burden. In Spain, data of total water intake (TWI) are scarce. There is a clear need for a national study that quantifies water and beverage intakes and explores associations between the types of beverages and energy intakes. METHODS The Anthropometry, Intake and Energy Balance Study ANIBES is a natio...

INTRODUCTION Accidental immersion in cold water is a risk factor for many occupations. Habituation to cold-water immersion (CWI) is one practical means of reducing the cold shock response (CSR) on immersion. We investigated whether repeated thermoneutral water immersion (TWI) induced a perceptual habituation (i.e., could lessen perceived threat and anxiety) and consequently reduce the CSR on su...

A two-dimensional (2D) dynamically reconfigurable metasurface aperture is presented to perform frequency selective through wall imaging (TWI) with an unknown structure of the wall. Generally, in TWI, medium properties and thickness need be known advance, which not always possible. Moreover, compensating for these effects can significantly increase computational complexity. We propose a two-stag...

BACKGROUND Patients with thymoma with immunodeficiency (TWI)/Good's syndrome characteristically have evidence of combined immunodeficiency including low or absent B-cells, hypogammaglobulinemia and defects in T-cell mediated immunity. These patients can present with common or opportunistic infections. CASE PRESENTATION A 54-year-old female was diagnosed with cerebral toxoplasmosis. This occur...

We have used a novel cell marker, in which the twist promoter directs the synthesis of the cell surface protein CD2 (twi-CD2) to examine the development of the mesoderm in the Drosophila embryo after gastrulation and to locate the progenitor cell populations for different mesodermal derivatives. We find that the early mesoderm in each segment is divided into a more anterior region with relative...

Some of the 'early adopters' of risk-based inspection (RBI) failed to cross the RBI technology chasm because as pioneers, they were essentially experimenting with the suitability of this new technology, Figure.1. The followers ('early and late majority') can benefit from the experiences (failures and successes) of these trailblazers. RBI has received considerable attention since the American So...

Lipid rafts (LRs) are membrane realms characterized by high concentrations of cholesterol and sphingolipids. Often, they are portrayed as scaffolds on which many different signaling molecules can assemble their cascades. The idea of rafts as scaffolds is garnering significant attention as the consequences of LR disruption have been shown to be manifest in multiple signaling pathways. In this st...

BACKGROUND When cooking on a barbecue grill, consumers often use aluminum grill pans. For one, the pan catches the fats and oils that would drip into the embers causing the formation of potentially noxious smoke, and the pan also protects the food from being burned by direct heat from the coals. In addition, new aluminum products for use in ovens and grills are becoming increasingly popular. Du...
