A methodological study using conjoint measurement analysis to determine whether there is an appropriate model for measuring commitment to work in the job-family trade-off context was conducted with 213 University of Michigan students and staff as subjects. The results indicate that there are two important dimensions that can be measured: a preference for a level of involvement in the total work...
Salah satu penyakit penting terbawa benih adalah pembuluh yang disebabkan bakteri Leifsonia xyli sub sp xyli. Perlakuan LHWT dapat mengendalikan tersebut tetapi menyebabkan penurunan perkecambahan. Tujuan penelitian untuk mengetahui pengaruh terhadap perkecambahan beberapa varietas tebu bina dan produksi varieta bina. Penelitian dilakukan pada tahun 2015, di P3GI Pasuruan Jawa Timur. Bahan digu...
Cow milk, a highly nutritious food item, is amenable to quality degradation due to lipolysis and proteolysis, as a sequel to the growth of spoilage microorganisms, particularly under ambient condition in tropical countries, with consequential loss of aesthetic appeal and product output. Prescription antibiotics used for milk preservation have many undesirable side effects on the health of consu...
The various precipitation types formed within winter storms (such as snow, wet snow and freezing rain) often lead to very hazardous weather conditions. These types of precipitation often occur during the passage of a warm front as a warm air mass ascends over a cold air mass. To address this issue further, we used a one-dimensional kinematic cloud model to simulate this gentle ascent (≤10 cm/s)...
It is know that a heat exchange tube with flat-oval profile has excellent thermal and aerodynamic characteristics in contrast to round tube. Thus, the same planes, flat significant increase efficiency compared tube, which widely used industry. However, at present, there are limited number of publications on study transfer aerodynamics inside pipe.
 In this paper, we present methodology res...
Chemical stability in propellants is important issue. In this article chemical and thermal stability for two kinds of double and single base propellants are investigated. In mass loss test in 90 0C, after 18 days mass loss for both samples is no more than 3%. By stabilizer measurement it was evident that remaining stabilizer content in aged samples are more than 10% in relative to fresh samples...
The current state of regeneration sulfate solutions was analyzed, it established that the existing physico-chemical methods do not solve problem sulfuric acid, but only neutralize it, for transfer according to standards MPC neutralization and into sewage system with subsequent disposal. It has been confirmed is advisable carry out by an electrochemical method using a three-chamber electrolyzer,...
در این پژوهش با استفاده از داده های اندازه گیری شده پارامترهای هیدرو فیزیکی دما، شوری و عمق در سال 2003 میلادی توسط پژوهشگاه علوم اقیانوس شناسی و جوی (سواحل بابلسر)، در ابتدا سرعت صوت در فصول مختلف سال طبق رابطه ی مدوین محاسبه گردید. سپس، نیمرخ های افقی و قائم دما، شوری و سرعت صوت با استفاده از نرم افزار matlab ترسیم شد. نتایج حاصل از تجزیه وتحلیل این نیمرخ ها نشان داد که در فصل تابستان و پاییز...
Hafnium oxide (HfO2) high-k thin films have been deposited by radio frequency (rf) sputtering technique on p-type Si (100) substrate. The thickness, composition and phases of films in relation to annealing temperatures have been investigated by using cross sectional FE-SEM (Field Emission Scanning Electron Microscope) and grazing incidence x-ray diffraction (GI-XRD), respectively. GIXRD analysi...
We report on measurements of quantum electrodynamic processes in an intense electromagnetic wave, where nonlinear e ects (both multiphoton and vacuum polarization) are prominent. Nonlinear Compton scattering and electronpositron pair production have been observed in collisions of 46.6 GeV and 49.1 GeV electrons of the Final Focus Test Beam at SLAC with terawatt pulses of 1053 nm and 527 nm wave...
