this research explores the possible benefits to be derived from interactions between wheels, for supporting a greater proportion of applied loads in the shallower soil layers. this creates possibilities for reducing the risk of deep soil compaction. previous research indicated that different interaction modes occurred under simulated wheel arrangements, being mostly dependent upon the spacing b...

conventional passive distribution networks are changing to modern active distribution networks which are not radial. conventional load flow methods should be modified for new distribution networks analysis. in modern distribution networks distributed generation (dg) units are embedded with conventional and/or renewable resources. dg units are generally modeled as pv or pq nodes which inject ...

the presence of microbial load and high fiber content in various non conventional feedstuffs limit their utilization in poultry feed. in the present study, the feedstuffs were treated with acidified sodium chlorite (asc) and its impact on  the microbial load and metabolizable energy availability was assessed in  the chickens. the effect of supplementation of feed grade enzyme was also evaluated...

background: in recent decades, studies on type 2 diabetes (t2d), have adopted a new approach to the field of a more complete collection of variables related to the lifestyles and diet of people. diet is an important factor in increasing the rate of t2d among individuals. considering the consumption of a high-carbohydrate diet, little attention has been paid to the type of carbohydrates consumed...

objective : the aim of this study was to evaluate fracture characteristics of rigid two-tooth segments splinted with fiber reinforced composite (frc), with and without application of simulated masticatory forces. material and methods: in this experimental study, 80 extracted maxillary bicuspids were joined in pairs from the buccal aspect using frc. the specimens were divided into two groups. in...

background: successful treatment to eliminate hcv rna depends on the identified genotype. in the present study, we com­pared the frequency of different hcv genotypes, during four years study (2004 till 2008).  methods: sera specimens were received from 16 provinces of iran. we used high pure viral nucleic acid purification kit for extraction and samples were tested with improved form of rt-pcr ...

it is proposed to use a single base platform in the persian gulf considering its low depth and more appropriate environmental conditions in comparison to north sea and mexico gulf where this kind of platform is very popular. the pile of platform is responsible for transmission of environmental loads resulted from waves, currents, wind and dead loads to foundation of platform. using sacs 5.3 sof...

with the expanding demand on application of magnesium alloys in automotive and aerospace industries, robust methods in fatigue characterization of commercially available magnesium alloys with high specific strength is anticipated. in this paper, rotating bending load controlled tests has been studied on specimens machined from an extrusion piece of az31b. due to asymmetric and anisotropic behav...
