over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
Abstract Background and Aims: EBV is a human herpesvirus that infects more than 90% of the world’s population. Although, benign and asymptomatic in most cases, the infection can cause many nonmalignant and malignant disorders of lymphoid and epithelial origins. The objective of this study was detected in IM prevalence in Neyshabur, Northeast Iran from 2010-2014. Materials and Meth...
Background: Determining the mortality rate of diseases in a community is one of the main components in health care planning of that community. This study used a join point regression model to determine the trend of mortality due to diabetes mellitus (DM) in Iran. Materials and Methods: The data on the rate of mortality due to DM were obtained from the reports of the Iranian Ministry of Healt...
The surface displacement by seasonally freezing bulge and thawing subsidence are main hazards for engineering construction in permafrost regions, especially for the Qinghai-Tibet railway. For detecting the distortion at permafrost area, we try to study the interferometric method of monitoring the deformation at permafrost area with time-series EnviSat ASAR data. In this paper, the coherence cha...
در مطالعه فونستیکی که طی سال های 1389- 1388 به منظور جمع آوری و شناسایی کنه های راسته پیش استیگمایان پارک جنگلی فندقلوی اردبیل انجام گرفت تعداد 150 اسلاید میکروسکوپی از مجموع نمونه های جمع-آوری شده تهیه و شناسایی گردید. در این مطالعه در مجموع 22 گونه و 19 جنس متعلق به 11 خانواده از راسته پیش استیگمایان شناسایی گردید که از بین آن ها تعداد چهار گونه برای فون کنه های جهان، یک جنس و یک گونه برای ای...
In the rangelands of Iran, the lack of appropriate grazing management is one of the major problems ultimately leading to untimely and excessive grazing intensity of forage. Accordingly, most of the rangelands show a retrogression trend and poor conditions. In forage species, phenological stage is one of the most important criteria for range management. Bromus tomentellus species is an ...
there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...
Background: The aim of this study was to evaluate and compare the clinical and electrocardiographic (ECG) manifestations of benzodiazepines (BZs). Methods: In this retrospective study, all BZ-poisoned patients hospitalized at Loghman Hakim Hospital between September 2010 and March 2011 were evaluated. Patients’ information including age, sex, time elapsed between the ingestion and presenta...
