This study models the flexural strength of concrete modified with cashew nutshell ash (CNA) using reactivity index concepts. Cashew was valorised and its used at 5, 10, 15 20 wt.% cement via mix proportions grades C 25–40 targeted MPa 28 days. The indexes (RIs) were evaluated based on oxide compositions chemical moduli both CNA. design parameters, water/binder binder/aggregate ratios, RIs appli...
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
BACKGROUND Mind-body interventions are used to alleviate physical and psychological symptoms. The multidimensional assessment of interoceptive awareness (MAIA), which is used to self-report the effects of mind-body interventions, is not currently available in Chinese. PURPOSE This study aimed to translate the MAIA from English into Chinese (MAIA-C) and to examine the psychometric properties o...
The dose-response relationship of the ionophore tetronasin was defined in growing-finishing cattle (84 heifers and 84 steers). Cattle were allotted by sex and weight replication (light and heavy) to 24 pens. Six dosages (D) of tetronasin (0, 3.7, 7.3, 11.0, 14.7 and 18.3 mg/kg, dry matter [DM] basis) were fed. Diets containing 40, 25 and 10% roughage were fed for 84, 56 and either 56 (heavy rep...
In this study, we examined whether Sprague-Dawley rats obtained from two different vendors, Harlan and Sasco, differ with respect to the types of alpha-2 adrenoceptors in the spinal cord that mediate antinociception. This hypothesis was tested using two alpha-2 adrenoceptor agonists, dexmedetomidine and ST-91, which are relatively selective for alpha-2A and alpha-2B adrenoceptors, respectively,...
Introduction: The aim of this study was to design a standard questionnaire facilitating the evaluation of the knowledge and attitude of medical students regarding radiation protection. Methods: At first, a 30-item questionnaire was prepared. The scale construction procedure was performed using content validity assessment. Considering objectives, some items were...
BACKGROUND Millions of workers are the victims of different kinds of accidents every year throughout the world. The purpose of this study was to investigate the relationships between safety attitude and occurrence of the occupational accidents. METHODS This investigation was a cross-sectional study performed in a gas refinery in south of Iran in 2008. Sample size of this study was 176 people....
Objective: The aim of this study was to evaluate different aspects of validity and reliability of the Persian-version of Fatigue Severity Scale (FSS-P) among people with Multiple Sclerosis. Materials & Methods: A sample of 50 people with Multiple Sclerosis and 30 healthy adults were included in this study. The participants were recruited from Sina clinic in Tehran between 2001 to 2007. The F...
