We report on a measurement of the asymmetry in the scattering of transversely polarized electrons off unpolarized protons, A( perpendicular), at two Q2 values of 0.106 and 0.230 (GeV/c)(2) and a scattering angle of 30 degrees <theta(e)<40 degrees . The measured transverse asymmetries are A( perpendicular)(Q(2)=0.106 (GeV/c)(2))=(-8.59+/-0.89(stat)+/-0.75(syst))x10(-6) and A( perpendicular)(Q(2)...
این تحقیق به منظور بررسی تأثیرات سطوح گوناگون عصارۀ تفالۀ انگور بر تولید گاز به روش آزمایشگاهی و برخی پارامترهای تخمیر شکمبه مانند سوبسترای تجزیه شده، اسیدهای چرب فرّار، و تولید پروتئین میکروبی با استفاده از شیرابۀ شکمبه گوسفند انجام شد. برای تهیۀ عصاره، تفالۀ انگور خشک با نسبت وزنی مساوی با آب مقطر مخلوط گردید و در سطوح صفر، 15، و 30 میلی گرم ترکیبات فنولیک کل به ازای گرم مادۀ خشک به جیرۀ پایه ...
Intorduction: It is necessary to notice the subjective well-being and satisfaction of human resources in organizations and lack of attention to them has deleterious effects on individual and organizational performance. Method: The present study is a mixed (qualitative and quantitative) research which used the Q approach to examine and explain managers’ mental patterns regarding Subjective We...

The coherent Sc Q , and single-particle Ss Q , dynamic structure factors which contribute to the lowenergy spectrum of molten potassium are separated by means of neutron polarization analysis. The linewidth and amplitude of the single-particle spectra follow an apparent sub-Fickian behavior, with a diffusion coefficient below the value found by macroscopic means. Once this is accounted for, the...
In this paper, it is proved that every s-sparse vector x ∈ R can be exactly recovered from the measurement vector z = Ax ∈ R via some `-minimization with 0 < q ≤ 1, as soon as each s-sparse vector x ∈ R is uniquely determined by the measurement z. Moreover it is shown that the exponent q in the `-minimization can be so chosen to be about 0.6796× (1− δ2s(A)), where δ2s(A) is the restricted isome...
In this paper is study the role of Measurement noise covariance R and Process noise covariance Q. As both the parameter in the Kalman filter is a important parameter to decide the estimation closeness to the True value , Speed and Bandwidth [1] . First of the most important work in integration is to consider the realistic dynamic model covariance matrix Q and measurement noise covariance matrix...
Paul Stoler Physics Department, Rensselaer Polytechnic Institute, Troy, NY 12180 Abstract It is suggested that the falloff in Q of the P → ∆ magnetic form factor G∗M is related to the recently observed falloff of the elastic electric form factor GEp/GMp. Calculation is carried out in the framework of a two-body GPD mechanism. The P → ∆(1232) form factor G∗M exhibits a more rapid decrease with r...
ین پایان نامه با هدف سنتز و شناسایی چهار نوع از نانو ذرات آغاز می شود. نانو ذرات آلوم اکسان از واکنش بوهمیت و کربوکسیلیک اسید مربوطه حاصل شدند. هدف از سنتز این نوع نانو ذرات ساخت غشاهای عامل دار شده با خاصیت آب دوستی و انتخاب پذیری جهت جداسازی روغن از مخلوط های آب و روغن، می باشد. tg-dta، ftir، sem، tem، uv/vis spectrophotometer، digital camera،contact angle measurement goniometer، ultrasonic b...
