In this work, the experimental study of spectral broadening due to stimulated Raman scattering with respect variation input power pulsed laser, as well a 4 m length high-numerical aperture fiber 100 and 500 non-zero dispersion-shifted is reported. The results showed extreme spectrum which known supercontinuum generation, originated by self-phase modulation, four- wave mixing dominated cascaded ...
AIM The spatial structure of a population can strongly influence the dynamics of infectious diseases, yet rarely is the underlying structure quantified. A case in point is plague, an infectious zoonotic disease caused by the bacterium Yersinia pestis. Plague dynamics within the Central Asian desert plague focus have been extensively modelled in recent years, but always with strong uniformity as...
this study examined the spawning characteristics and distribution of mullus barbatus and upeneus moluccensis in babadillimani bight, in the northeastern mediterranean (near mersin, turkey) between of may 1999 and april 2000. sampling was carried out monthly at depths of 0-50 m, 50-100 m and >100 m using commercial trawl net mesh size 22 mm knot to knot. the results showed no difference between ...
We describe the use of a silver-coated 90? parabolic mirror 33 mm focal length as objective for imaging, on-axis laser heating and radiospectrometric temperature measurements sample compressed in diamond anvil cell system. There, spatial resolution imaging quality are similar to one 10× objective. The between 500 900 nm essentially free from chromatic aberration. was also perforated with 220-?m...
چکیده- اثر مایهزنی جداگانه و توام دو جدایه bacillus mycoides و micrococcus roseus بومی خاکهای آلوده به فلزات سنگین بر رشد گیاه و جذب عناصر غذایی ضروری و نیکل توسط گیاه ذرت در خاک آلوده به سطوح 250 و 500 میلیگرم نیکل در کیلوگرم خاک طی آزمایش گلدانی بررسی گردید. در هر یک از سطوح نیکل، وزن خشک اندامهوایی و جذب عناصر غذایی در تیمارهای m. roseus و b. mycoides در مقایسه با شاهد افزایش معنیداری ...
