conclusions this was the first study that focused on expanding resilience indicators, and presents a new framework to simplify assessment of resilience and safety of a complex system. results in this study, 29 factors affecting this indicator were determined using the delphi method; the scores of all factors were less than the scores of the best practice. on the other hand, the state of this in...
background: human immunodeficiency virus (hiv) causes severe immunosuppression due to progressive decrease in the cd4 t lymphocyte cells during the course of the disease and this affects all the body systems including glandular secretions. a number of lesions affecting the salivary glands have been noted in hiv infection. the objective of this study was to evaluate the salivary ph and the buffe...
Background & Aims: Pregnancy duration is crucial regarding dental problems. So the aim of this study was to determine the association between pregnancy period and PH, S. Mutans, and buffering capacity of saliva. Materials & Methods: This cross sectional study was done among 120 women who referred to the Gynecology hospital in Baku with an average of 24.1± 2.91 years...
چکیده: هدف از مطالعه حاضر پیش بینی ظرفیت های هوازی و بی هوازی ورزشکاران نخبه با استفاده ازتغییرات لاکتات در مرحله بافرینگ ایزوکاپنیا بود. 8 دوچرخه سوار اسقامتی نخبه و 6 دوچرخه سوار سرعتی نخبه که همگی عضو باشگاه ورزشی عقاب، ترافیک و پاسارگاد بودند، در این تحقیق شرکت کردند و در دو جلسه مجزا با فاصله زمانی یک هفته یک آزمون فزاینده استاندارد و یک آزمون فرابیشینه یکنواخت را تا سر حد واماندگی انجام ...
Phosphate sorption by soils is one of the most important processes indicating the buffering power and availability of P for plants. Phosphorus sorption characteristics of eight representative calcareous soil of Isfahan region were evaluated. For this purpose, 3 grams, of < 2-mm soil were equilibrated for 24 hours at 25±l °C in 60 ml of 0.01 M CaCl2 with varying amounts of P. Sorbed phosphorus w...

Aim of the study is to evaluate the correlation between dental caries and salivary flow, pH and buffering capacity in young adult South Indian population. According to DMFT scores eighty subjects between 20 to 30 years of age were divided into four groups. Saliva samples collected were estimated for salivary flow, pH and buffering capacity and the data was statistically analysed. The pH, flow r...
Saliva buffering test is in need of improvements. This article illustrates the most commonly used saliva buffering capacity tests and its major problems. Starting with Ericsson and his laboratory buffer capacity test and all the way to Kitasako a lot of issues are to release. The aim of this paper is to put saliva buffering tests up to serious discussion.
