The effect of sex, age and weight on blood lipids in a Chinese population over 45 years old and related factors
Blood lipids are a major risk factor for coronary heart disease (CHD), and they change distinctly after the fourth decade in humans. In order to understand the relationships between blood lipids and sex, age, and weight in individuals over 45 years old, we recruited 362 healthy males aged 45-87 years (mean ± SD, 62.9 ± 11.3) and 297 healthy females aged 45-107 years (mean ± SD, 61.0...

The clinical characteristics of the benign paroxysmal positional vertigo associated with sudden sensorineural hearing loss
To explore the clinical characteristics of the benign paroxysmal positional vertigo (BPPV) associated with sudden sensorineural hearing loss (SSHL) (throughretrospective analysis of 19 cases from June 2008 to June 2010) and improve the diagnosis and treatment. Nineteen cases (7 male and 12 female, aged 46 to 68 years old) of BPPV associated with SSHL from June 2008 to June 2010 were retrospectively...

Response of weed flora to different herbicides in aerobic rice system
Weed is the major limitation to the adoption of aerobic rice system, the most potential water saving rice production technology. Herbicide is the appropriate tool to address this problem but suitable herbicide or their combination in controlling the predominant weed flora in this system is not established. The present study was conducted to evaluate the response of weed flora in the aerobic rice field to the sequential...

Modification of the dynamic scale of marks in analytic hierarchy process (ahp) and analytic network approach (anp) through application of fuzzy approach
There are two mainstreams in the use of the analytic network process (ANP) and analytic hierarchy process (AHP). One is the standard applications of crisp distributive and ideal mode versions. The other is characterised by fuzzification of the AHP/ANP methodology and by attempts to tackle better inherently uncertain and imprecise decision processes with quantitative and qualitative data. This paper presents...

Methodology for establishing the routes for transportation of dangerous goods on the basis of the risk level - Case study: City of Belgrade
This paper contains presentation of methodology, that is, the steps which have to be taken in order to establish the routes for transportation of dangerous goods. The methodology is developed by the authors of the paper, while the selection of routes for transportation of dangerous goods is based on determination of the extent of risk. The model used for determining the risk level for the selection of routes is the work...

Maternal risk factors associated with preterm delivery in Qom province of Iran in 2008
Immaturity is the most important factor of infant mortality. Knowing what group of pregnant women are more at risk of preterm delivery provides opportunities for more accurate care during pregnancy and rapid diagnosis of complications with trying tofix and make them to prevent preterm delivery. The objective of this study is to compare the maternal risk factors in...

Control of the seed beetle Callosobruchus muculatus reared on chickpeas by different applicable conditions of the insect growth regulator, Cyromazine
Efficiency of most pesticides is monitored by many factors such as the method of application, the concentrations and the temperature. The study was aimed to investigate the optimal conditions for using Insect Growth Regulator (IGR), cyromazine to control the Southern cowpea weevil Callosobruchus muculatus Fab. (Bruchidae: Coleoptera). Interactions of the method of application and concentrations of cyromazine...

Expressing of rice ribosome inactivating protein as tool for treatment of cancer cells
Ribosome-inactivating proteins (RIPs) are toxic proteins synthesized by many plants and some bacteria, that specifically depurinate the 28S RNA and thus interrupt protein translation. RIPs hold broad interest because of their potential use as plant defense factors against pathogens and cancer cells. The most promising way to exploit plant RIPs as weapons against cancer cells is either by designing molecules in which the...

Biodegradation of pyrene by a newly isolated Proteus vulgaris
This work was aimed at identifying a new strain which can degrade pyrene effectively and quickly. Strain 4Bi was identified as Proteus vulgaris based on several morphological, biochemical characters and 16S rRNA phylogeny by using conventional methods, API and 16S rRNA gene sequence analysis. 16S rRNA gene sequence of the bacterium has been deposited in GenBank database under the accession number FJ799903....

Optimization of seed flow evenness of fluted rolls used in seed drills by Taguchi method
The purpose of this study is to optimize the seed flow evenness in seed drills of the fluted feed rolls; wheat was used in the experiments. Experiments were conducted according to Taguchi optimization method and L9 orthogonal array is selected. Flute shape (asymmetric, trapezoid and semicircular), flute lengths (5, 10 and 15 mm), and axis rotational speed (25, 30, and 35 min-1), and coefficient of variation used to...

Efficiency and resolution of HPGe and NaI(Tl) detectors using gamma-ray spectroscopy
The energy dependence of efficiency and resolution of HPGe and NaI(Tl) detectors using gamma-ray spectroscopy were investigated in this paper. It was found that the resolution of the detector was directly proportional to the energy of gamma-ray and its efficiency was exponentially proportional to the gamma-ray energy. The resolution of HPGe detector (GC2018, diameter 60.5 mm and length 31.5 mm) is better than NaI(Tl)...
