objective: to evaluate the prevalence of gestational diabetes mellitus (gdm) and its risk factors in tehran. materials and methods: from march 2002 to october 2004, screening for gdm was performed on 1804 women in tehran. all pregnant women were referred for a 50 g oral glucose challenge test (ogct) between 24th and 28th week of gestation. all subjects with an abnormal gct (blood glucose level ...

Today, people use a variety of digital devices, and events taking place in them are stored in specific forms mostly including data indicating when each event took place. So far, different methods have been constantly researched and developed to analyse various events, most of which analyse event data unnecessary for a forensic investigation. As a result, investigators should carry out additiona...

We demonstrate recording and reconstruction of multiple-computer-generated wavelength-multiplexed volume holograms in a holographic storage medium. The holograms display high selectivity, and their reconstruction process results in a convenient conversion of wavelength into angular multiplexing.

We study the dynamics of crystallization in phase-change materials using a master-equation approach in which the state of the crystallizing material is described by a cluster size distribution function. A model is developed using the thermodynamics of the processes involved and representing the clusters of size two and greater as a continuum but clusters of size one (monomers) as a separate equ...

Systems of globally coupled phase oscillators can have robust attractors that are heteroclinic networks. We investigate such a heteroclinic network between partially synchronized states where the phases cluster into three groups. For the coupling considered there exist 30 different three-cluster states in the case of five oscillators. We study the structure of the heteroclinic network and demon...

Aim. To establish a new score model to predict risk of death in patients with hepatocellular carcinoma and type 2 diabetes mellitus. Methods. This was a retrospective study of 147 patients with hepatocellular carcinoma and type 2 diabetes mellitus who came to Beijing Ditan Hospital between October 2008 and June 2013. Univariate and multivariate logistic regression analysis was performed to obta...

Heat stress in cattle results in millions of dollars in lost revenue each year due to production losses, and in extreme cases, death. Death losses are more likely to result from animals vulnerable to heat stress. A study was conducted to determine risk factors for heat stress in feedlot heifers. Over two consecutive summers, a total of 256 feedlot heifers (32/ breed/ year) of four breeds were o...
