تونل قمرود به طول کلی 7/35 کیلومتر از جمله طرح­های بزرگ ملی است. برای حفاری قطعه 1 آن به طول 311+11 کیلومتر دستگاه tbm از نوع epb انتخاب شده است. برای پیش­بینی نرخ پیشروی و به تبع آن زمان تکمیل حفاری و هزینه­ها، تخمین ضریب بهره­وری بسیار حائز اهمیت است. ضریب بهره­وری به­صورت زمان خالص حفاری به کل زمان در دسترس در هر واحد زمین­شناسی تعریف می­شود. این ضریب تابعی از شرایط زمین، نوع ماشین، تأسیسات ...

BACKGROUND Despite increasing awareness regarding evidence-based guidelines, considerable gaps exist for heart failure (HF) quality of care at teaching hospitals (TH) and nonteaching hospitals (NTH). We analyzed data from Get With The Guidelines (GWTG)-HF to compare the rates and trends of guideline-recommended care at TH and NTH for patients with HF. METHOD AND RESULTS Baseline patient chara...

Escherichia coli endonuclease VIII and endo-nuclease III are oxidative base excision repair DNA glycosylases that remove oxidized pyrimidines from DNA. The genes encoding these proteins, nei and nth, are both co-transcribed as the terminal genes in operons. nei is the terminal gene in an operon with four open reading frames that encode proteins of unknown function. This operon has two confirmed...

BACKGROUND The causes of neonatal transient hypothyroidism (NTH) remain incompletely understood. Whether it is influenced by genetic background is rarely discussed and remains unproven. A defect in thyroid peroxidase is a common cause of dyshormonogenesis of the thyroid gland in Taiwanese, with a novel mutation (2268insT) present in nearly 90% of alleles studied. OBJECTIVE To determine if the...

INTRODUCTION Infectious diseases are one of the major causes of child mortality in India. Pediatric patients are commonly prescribed antibiotics for non-bacterial infections. Monitoring of local antibiotic prescribing with respect to the diagnosis is necessary to improve the prescribing practices. The aim of the study was to describe antibiotic prescribing for potential infections among patient...

We investigate theoretically the nonlinear propagation of the limited diffraction Bessel beam in nonlinear media, under the successive approximation of the KZK equation. The result shows that the nth-order harmonic of the Bessel beam, like its fundamental component, is radially limited diffracting, and that the main beamwidth of the nth-order harmonic is exactly 1/n times that of the fundamental.

In growing cells, apurinic/apyrimidinic (AP) sites generated spontaneously or resulting from the enzymatic elimination of oxidized bases must be processed by AP endonucleases before they compromise cell integrity. Here, we investigated how AP sites and the processing of these noncoding lesions by the AP endonucleases Nfo, ExoA, and Nth contribute to the production of mutations (hisC952, metB5, ...
