The purpose of present study was to optimize polyhydroxyalkanotes (PHAs) production in a gamma ray mutant strain of Pseudomonas aeruginosa grown on soybean oil in minimal salts media under shake flask conditions. The production kinetics was studied by sampling on daily basis for 6 days to investigate the best conditions for PHAs production like biomass estimation, carbon source utilization and ...

In the paper we combine a Bayesian Network model for encoding forensic evidence during a given time interval with a Hidden Markov Model (EBN-HMM) for tracking and predicting the degree of criminal activity as it evolves over time. The model is evaluated with 500 randomly produced digital forensic scenarios and two specific forensic cases. The experimental results indicate that the model fits we...

background: burnout, a phenomenon that is of interest for both individuals and organizations, is characterized by decreasing energy, power and resources in the presence of excessive demands. nurses are more prone to develop burnout due to both the emotional nature of their jobs as well as patients' demand. the present study was aimed to assess burnout among nurses working in the iranian ho...

BACKGROUND Post-traumatic stress disorder (PTSD) comprises a collection of symptoms following exposure to injury-causing accidents of life. It is estimated that the prevalence of PTSD in children with malignancy and their parents is between 10-30% and even several years after treatment of malignancy this disorderremain in 20-20% of these patients. OBJECTIVES This study investigated the preval...

Whenever we encounter a research finding based on the interpretation of a p value from a statistical test, whether we realise it or not, we are discussing the result of a formal hypothesis test. This is true irrespective of whether the test involves comparisons of means, Odds Ratios (ORs), regression results or other types of statistical tests. As readers of research, it is important to underst...

OBJECTIVE Beta-thalassemia major (β-TM) is a chronic, genetic and hematological disorder. Children and teenagers with chronic physical illnesses exemplified by thalassemia are vulnerable to emotional and behavioral problems. The aim of this study was to evaluate mental health and its related factors among young patients with beta-thalassemia major. METHODS In this cross-sectional observationa...

In this paper, dynamic modeling of a Vestas 660 kW wind turbine and its validation are performed based on operational data extracted from Eoun-Ebn-Ali wind farm in Tabriz, Iran. The operational data show that the turbine under study, with a classical PI controller, encounters high fluctuations when controlling the output power at its rated value. The turbine modeling is performed by deriving th...
