Background: Feedback is an essential element of the educational process for clinical trainees. Performance-based feedback enables good habits to be reinforced and faulty ones to be corrected. Despite its importance, most trainees feel that they do not receive adequate feedback and if they do, the process is not effective. Aims and methods: The authors reviewed the literature on feedback and pre...

امروزه استفاده از وب به یکی از عناصر حیاتی زندگی انسانی تبدیل شده است. حتی در بسیاری از جوامع زندگی روزمره آدمی در صورت اختلال در وب دچار مشکلات اساسی می شود. به همین دلیل حجم اطلاعاتی متنی در وب به طرز چشمگیری افزایش یافته است. حتی به صورت شهودی نیز می توان ادعا نمود که نرخ رشد اطلاعات متنی در دنیای امروزه از نرخ رشد داده به هر شکل دیگری مانند صوت، تصویر و ... بالاتر است. کاربران در میان این د...

In order to better understand the cellular delivery of iron from serum transferrin (Tf), we compared iron release from receptor-bound and free Tf. While free Tf did not release all iron until below pH 4.6, receptor-bound Tf released significantly more iron at mildly acidic pH, with essentially all iron released between pH 5.6 and 6.0. Since Tf is acidified to a minimum pH of 5.4 in K562 cells, ...

PURPOSE Tissue factor (TF) plays an important role in neovascularization (NV). This study aimed to determine whether small interfering RNA-targeting TF (TF-siRNA) could knock down TF expression and inhibit cell proliferation, cell migration, and tube formation in an in vitro model of NV. METHODS Lipopolysaccharide (LPS) was used to stimulate human umbilical vein endothelial cell (HUVEC) lines...

this paper deals with the use of transferring (tf) system in legal medicine and forensic serology. biased upon the clear for mal genetics and excellent typing of tf phenotypes, in case of rare tf variants, favorable results are obtained in disputed paternity. in the present case of disputed paternity, the child and the father exhibits b2 c type while the mother shows the type cc. but the father...

This study investigated the performance of steers grazing rhizomatous birdsfoot trefoil (Lotus corniculatus L.) (RBFT) compared to nonrhizomatous birdsfoot trefoil (BFT) in pure stands or when interseeded with endophyte-free tall fescue (Festuca arundinacea Schreb.; TF). Five forage treatments of RBFT, BFT, TF, RBFT+TF, and BFT+TF (four replicate paddocks per treatment) were continuously stocke...

the effects of trigonella foenum graecum (tf) and foeniculum vulgare (fv) seeds powder on antimicro-bial activity and performance of broiler chickens were studied. based on a completely randomized design, 240 broiler chicks (ross 308) were assigned to 4 treatments and 4 replicates. the treatments were a basal diet (control, t 1), t 1 plus 0.5% tf (t 2), t 1 plus 0.5% fv (t 3) and tffv (0.25% tf...

We determined if sequence of ingestion affected use of endophyte-infected tall fescue (TF) when cattle also grazed birdsfoot trefoil (BFT) or alfalfa (ALF). Based on chemical characteristics of TF (alkaloids), BFT (tannins), and ALF (saponins), we hypothesized that cattle first allowed to graze ALF or BFT would subsequently spend more time grazing TF than cattle that first grazed TF followed by...

We consider the problems of designing a linear, time-varying filter with a specified " time-frequency (TF) pass region " and of constructing an orthonormal basis for the parsimonious expansion of signals located in a given TF support region. These problems of TF filtering and TF signal expunsion are reduced to the problem of designing a " TF subspace, " i.e., a linear signal space comprising al...
