در این تحقیق واکنش تشکیل کمپلکس بین کاتیون های tl+، ag+ و +2pb با 2و6-دی(فوران-2ایل)-4-(4-متوکسی فنیل)پیریدین (dfmp) به عنوان یک لیگاند سنتزی جدید در سیستم های دو جزئی استونیتریل(an)–آب(o2h)و متانول(meoh)–آب(o2h)در دماهای مختلف بوسیله تکنیک هدایت سنجی مورد مطالعه قرار گرفت.
This paper demonstrates the performance of PERT, a new TCP congestion control, for video streaming. PERT stands for Probabilistic Early Response TCP. As a delay based protocol, it measures the delay at the end host and adjusts the congestion window accordingly. As our NS-2 simulation results show, the late packet of the video streams are greatly decreased when applying PERT in heterogeneous env...
OBJECTIVE The benefits of pancreatic enzyme replacement therapy (PERT) in chronic pancreatitis (CP) are inadequately defined. We have undertaken a systematic review and meta-analysis of randomised controlled trials of PERT to determine the efficacy of PERT in exocrine pancreatic insufficiency (EPI) from CP. DESIGN Major databases were searched from 1966 to 2015 inclusive. The primary outcome ...
Difficulties with the interpretation of the parameters of the beta distribution let Malcolm et al. (1959) to suggest in the Program Evaluation and Review Technique (PERT) their by now classical expressions for the mean and variance for activity completion for practical applications. In this note, we shall provide an alternative for the PERT variance expression addressing a concern raised by Hah...
Adapting a Delay-based Protocol to Heterogeneous Environments. (August 2008) Kiran Kotla, B.E., Birla Institute of Technology and Science, Pilani, India Co–Chairs of Advisory Committee: Dr A. L. Narasimha Reddy Dr Riccardo Bettati We investigate the issues in making a delay-based protocol adaptive to heterogeneous environments. We assess and address the problems a delay-based protocol faces whe...
AIM Because of increasing awareness of variations in the use of pancreatic exocrine replacement therapy, the Australasian Pancreatic Club decided it was timely to re-review the literature and create new Australasian guidelines for the management of pancreatic exocrine insufficiency (PEI). METHODS A working party of expert clinicians was convened and initially determined that by dividing the t...
Phenol emulsion reassociation technique (PERT) greatly enhances the rate of DNA hybridization in solution over typical hybridization conditions (1) and has successfully been used to accelerate competitive DNA reassociation for performing subtraction based genomic cloning (2-5). PERT is accomplished through the establishment and maintenance of a phenol emulsion, typically by mechanical vortexing...
More than half a century after the debut of CPM and PERT, we still lack a project scheduling system with calibrated and validated distributions and without requiring complex user input. Modern decision support systems (DSS) for project management are more sophisticated and comprehensive than PERT/CPM. Nonetheless, in terms of stochastic analysis, they show insufficient progress. PERT 21 offers ...
Pancreatic enzyme replacement therapy (PERT) is the only treatment for malabsorption in cystic fibrosis (CF) caused by pancreatic insufficiency (PI). PI occurs in approximately 85% of patients with CF. PERT overcomes some, but not all the signs and symptoms of malabsorption. Clinical parameters such as growth, abdominal pain, diarrhea and gassiness, commonly used to adjust PERT dosing, are show...
