ترکیبات آزو به ملکولهایی که دارای یک یا چند پیوند آزویک (-N=N-) باشند اطلاق میگردد. پیوندهای مزبور ساختارهای حلقوی را به یکدیگر متصل میکنند. این رنگها بزرگترین طبقه رنگهای مورد استفاده در نساجی و دیگر صنایع میباشند. در صنایع نساجی حدود 15 درصد از رنگزاهای مصرفی طی فرآیند رنگرزی وارد پسابهای نساجی میشوند. رهاسازی این ترکیبات در محیط بسیار نامطلوب است، زیرا تعدادی از این رنگها و محصولات ح...
Historically, diagnostic radiology residents have been allowed time off from clinical duties to study for the ABR oral board examination. This practice has resulted in a disruptive "board frenzy" at many programs. The new ABR examination structure gives programs an opportunity to evaluate this practice. This position statement of the Association of Program Directors in Radiology describes the r...
The Available Bit Service (ABR) is a promising “best effort” service designed to achieve in ATM networks high efficiency and low cell loss. Since the ATM Forum approved a first standard, intensive research has been done about ABR. The aim of this paper is to analyse the main research topics involved in ABR, namely: the evaluation of traffic and congestion control schemes, conformance definition...
In this paper, we present an analysis of an existing ratebased ABR scheduling algorithm described in [1], and propose an enhanced rate-based round robin (RBR) scheduling algorithm for ATM switches and end systems. One of the novel aspects of RBR is that the scheduler supports available bit rate (ABR) traffic as well as guaranteed bandwidth reservations. In addition, bandwidth overbooking is all...
Twenty-four participants, consisting of six sibling pairs and six non-sibling pairs, participated in this study investigating the familiality of auditory evoked potentials (AEPs). The auditory brainstem response (ABR) recorded at high stimulus rates, revealed that Wave V latency increases, while amplitude decreases as stimulus rate increases. ABR Wave V latency was also found to increase with c...
One of the more challenging and yet unresolved issues which is paramount to the success of ATM networks is that of congestion control for Available Bit Rate (ABR) traffic. Unlike other ATM service categories, ABR provides a feedback mechanism, allowing interior nodes to dictate source rates. Previous work has demonstrated how linear control theory can be utilized to create a stable and efficien...
One of the most important applications of the Brainstem evoked response audiometry (ABR) is in the evaluation of hearing loss in children. Today the ABR is also indicated in the screening of cochleo-vestibular syndromes to detect retrocochlear lesions, to monitor patients in a coma (brain death), in monitoring the brainstem during skull base surgery, etc. Among the many BERA qualities, is its c...
BACKGROUND Awareness about antibiotic resistance depends on the attitudes and information about antibiotic resistance of both patients and physicians. Persons who practice self-medication are at high risk of also self-medicating with antibiotics. The purpose of the present study was to evaluate the awareness about antibiotic resistance by investigating the practice in a group of self-medication...
BACKGROUND The analysis of the Auditory Brainstem Response (ABR) is of fundamental importance to the investigation of the auditory system behaviour, though its interpretation has a subjective nature because of the manual process employed in its study and the clinical experience required for its analysis. When analysing the ABR, clinicians are often interested in the identification of ABR signal...
The T lymphocytes are the most important effector cells in immunotherapy of cancer. The conceptual objective for developing the tumor targeted superantigen (TTS) ABR-217620 (naptumomab estafenatox, 5T4Fab-SEA/E-120), now in phase 3 studies for advanced renal cell cancer, was to selectively coat tumor cells with cytotoxic T lymphocytes (CTL) target structures functionally similar to natural CTL ...
