Genetic variability and heritability estimates with genetic advance of traits are essential for crop improvement. In this investigation, variability induced by gamma rays and ethyl methane sulphonate (EMS) for different quantitative traits including plant height (cm), flowering time (days), number of primary branches per plant, number of clusters per plant, number of pods per plant, number of s...

A unique controlled laser head with an adaptive module was developed to stabilize the trajectory of movement. The scientific and practical problem developing a technology for restoring inner surface small diameter up ?44 mm solved by introduction head. Adhesion achieved moving along vectors, forming regular pyramid opening angles at top. High physical mechanical properties restored pump were wh...

The enhancement of a hydrogen plasma treatment on the solid-phase crystallization of hydrogenated amorphous silicon has been applied to form single crystalline silicon islands at designed locations. Holes with diameters from 0.4 to 1.8 mm were opened in silicon nitride, and then amorphous silicon films within the holes were exposed to a hydrogen plasma to create microcrystalline seeds. After fu...

We have developed a scanning superconducting quantum interference device sSQUIDd microscope system with interchangeable sensor configurations for imaging magnetic fields of room-temperature sRTd samples with submillimeter resolution. The low-critical-temperature sTcd niobium-based monolithic SQUID sensors are mounted on the tip of a sapphire and thermally anchored to the helium reservoir. A 25 ...

the present study performed to examine canola meal on morphology of thyroid gland in broiler chicks. in this experiment 300 l-day-old unsexed ross broiler chicks assigned into 5 groups. the chicks were fed by five level of canola meal (0, 5, 10, 15 and 20%). after 42 days feeding four chicks from each pen killed and their thyroid glands removed and immediately were immersed in formaldehyde, bef...

to study response of bread wheat cv. sardari to row spacing and seeding rate and to determine the desirable seed density under cold rain-fed conditions a two-year study (2008 and 2009) was carried out in qamloo research station located in kurdistan. a strip plot design with three replications was used. four rows spacing including 15, 17.5, 20 and 25 cm as horizontal factor and four seeding rate...

BACKGROUND Aortic valve replacement (AVR) with a small aortic annulus is always challenging for the cardiac surgeon. In this study, we sought to evaluate the midterm performance of implantation with a 17-mm or 19-mm St. Jude Medical Regent (SJM Regent) mechanical valve in retrospective consecutive cohort of patients with small aortic annulus (diameter ≤ 19 mm). METHODS From January 2008 to Ap...
