in order to evaluate nitrogen fixation ability and nutrients uptake in three cultivars of common bean (phaseolus vulgaris l.) inoculating with some types of inoculants containing different strains of rhizobium leguminosarum; bv. phaseoli an experimental design was conducted in khoramdarah region in 2006 and 2007. in this investigation three types of biological fertilizers including rb117, rb123...

in order to study the biological fixation efficiency of different strains of symbiosis bacteria in three varieties of common bean (phaseolus vulgaris l.) a factorial experiment based on randomized complete block design was conducted in zanjan province during 2006 and 2007. in this investigation three strains of rizobium including: rb117 (extracted from the zanjan soils), rb123 (extracted from t...

A compact absorption spectrometer with a midinfrared tunable quantum cascade laser operating at 4.86 microm (2054 cm(-1)) is used to measure lower concentrations of carbonyl sulfide (COS) in air. A detection sensitivity of approximately 30 parts in 10(9) of COS and the selectivity of two stable isotopes, 12C(16)O32S and 12C(16)O34S, are demonstrated. Specifically, the feasibility of detecting C...

Background: Acetabular Retroversion (AR) is a hip disorder and one of the causes of pain in this area. Evaluationof positive Cross Over Sign (COS) on AP X-Rays of the hip is currently the best method of diagnosis of AR. Severalstudies have measured co-existence of Ischial Spine Sign (ISS) in patients with AR. In this study we evaluated thediagnostic value of ISS in confirmation of AR and compar...

Background: To determine whether random-start controlled ovarian stimulation (COS), in which a stimulation is performed regardless to day of patient’s menstrual cycle, has similar outcomes in comparison to conventional early follicular phase-start COS for cryopreservation of fertilized oocytes in cancer patients. Materials and Methods: This prospective study was performed at two infertility cen...

In transportation applications such as real-time route guidance, ramp metering, congestion pricing and special events traffic management, accurate short-term flow prediction is needed. For this purpose, paper proposes several novel online Grey system models (GM): GM(1,1|cos(?t)), GM(1,1|sin(?t),cos(?t)), GM(1,1|e-at,sin(?t),cos(?t)). To evaluate the performance of proposed models, they are comp...

The maturation and packaging of bacteriophage lambda DNA are under the control of the multifunctional viral terminase enzyme, which is composed of the protein products of Nu1 and A, the two most leftward genes of the phage chromosome. Terminase binds selectively to the cohesive end site (cos) of multimeric replicating lambda DNA and introduces staggered nicks to regenerate the 12-base single-st...
