We present in this paper a Herriott-cavity-assisted closed-loop Xe isotope gas comagnetometer. In system, $^{129}$Xe and $^{131}$Xe atoms are pumped probed by polarized Rb atoms, continuously driven oscillating magnetic fields, whose frequencies kept on resonance phase-locked loops (PLLs). Different from other schemes, we use Herriott cavity to improve the magnetometer sensitivity instead of pa...

livestock grazing is one of the most important kinds of land usage that has a high potential to decrease or increase carbon storage in rangeland ecosystem. this research was investigated the effects of enclosure on soil carbon storage in a rangeland with dominant plants of artemisia aucheri. hence, two rangelands of enclosure (shahtappeh-chah mahmood) and no enclosure (chiro) were chosen in sem...

background: the singh index is an inexpensive simple method to evaluate bone density, commonly used to assess osteoporosis is based on the radiological appearance of the trabecular bone structure of the proximal femur on a plain antero-posterior (ap) radiograph. the purpose of this study was to compare between singh index and bone mineral density measurement using dual energy x-ray absorptiomet...

nitrogen components of yoghurt milk samples and resulting probiotic set yoghurt weredetermined. analyses included total nitrogen (tn), non-casein nitrogen (ncn), non-proteinnitrogen (npn), casein nitrogen (cn) and proteolysis index (pi). yoghurt samples wereanalyzed 1, 7, 14 and 21days after production and storage at 5±1°c. tn, cn and pi contentsof yoghurt milk samples with high somatic cell sc...

OBJECTIVES To estimate the national prevalence of firearm ownership and storage practices in the home, to compare storage practices in homes with and without children, and to analyze demographic characteristics related to firearm storage practices in homes with children. DESIGN A 1994 random-digit dialing telephone survey. We weighted the data to provide national estimates. PARTICIPANTS Eng...

This paper describes a dual-loop delay-locked loop (DLL) which overcomes the problem of a limited delay range by using multiple voltage-controlled delay lines (VCDLs). A reference loop generates quadrature clocks, which are then delayed with controllable amounts by four VCDLs and multiplexed to generate the output clock in a main loop. This architecture enables the DLL to emulate the infinite-l...

BACKGROUND The 60(+) members of the mammalian Rab protein family group into subfamilies postulated to share common functionality. The Rab VI subfamily contains 5 Rab proteins, Rab6a/a', Rab6b, Rab6c and Rab41. High-level knockdown of Rab6a/a' has little effect on the tightly organized Golgi ribbon in HeLa cells as seen by fluorescence microscopy. In striking contrast, we found Rab41 was strongl...

the microstructure of dual phase steels can be considered as a matrix of ferrite phase reinforced by martensite particles. recent measurements show that the mechanical properties of the ferrite phase are changed with the distance from the martensite grains. in this paper, a new method has been proposed to consider this phenomenon in finite element modeling of dual phase steels microstructure. i...

Ion dynamics are investigated in a dual frequency radio frequency sheath as a function of radius above a 30 cm diameter biased silicon wafer in an industrial inductively coupled (440 kHz, 500 W) plasma etch tool. Ion velocity distribution (IVD) function measurements in the argon plasma are taken using laser induced fluorescence. Planar sheets of laser light enter the chamber both parallel and p...
