in this paper we consider the group algebra $r(c_2times d_infty)$. it is shown that $r(c_2times d_infty)$ can be represented by a $4times 4$ block circulant matrix. it is also shown that $mathcal{u}(mathbb{z}_2(c_2times d_infty))$ is infinitely generated.
let $cr_{n}(f)$ denote the algebra of $n times n$ circulant matrices over the field $f$. in this paper, we study the unit group of $cr_{n}(f_{p^m})$, where $f_{p^m}$ denotes the galois field of order $p^{m}$, $p$ prime.
in the present study, the effects of formalin as a peripheral noxious stimulus on spontaneously active units of the nucleus reticularis paragigantocellularis (pgi), a narrow region of the ventral pontine reticular formation, was examined in urethane anesthetized rats. spontaneous discharge of the pgi neurons was variable, ranging from i to 37 spikes per second. formalin as a chemical irritant a...
conclusions using eye mask can significantly improve the sleep quality in cardiac patients. therefore, nurses are recommended to use eye mask in combination with current treatments for improving patients’ sleep quality. results after the study, the median scores of the subjective sleep quality, the sleep latency, the sleep duration, the habitual sleep efficiency, and the sleep disturbances doma...
let $cr_n(f_p)$ denote the algebra of $n times n$ circulant matrices over $f_p$, the finite field of order $p$ a prime. the order of the unit groups $mathcal{u}(cr_3(f_p))$, $mathcal{u}(cr_4(f_p))$ and $mathcal{u}(cr_5(f_p))$ of algebras of circulant matrices over $f_p$ are computed.
Recent advances in software testing introduced parameterized unit tests (PUT), which accept parameters, unlike conventional unit tests (CUT), which do not accept parameters. PUTs are more beneficial than CUTs with regards to fault-detection capability, since PUTs help describe the behaviors of methods under test for all test arguments. In general, existing applications often include manually wr...
ایمنی نقش بسیار مهمی را در تمامی مراحل طراحی فرایندهای شیمیایی ایفا می کند. اگر چه صنعت فرایندهای شیمیایی یکی از ایمن ترین بخش های صنعت در دنیاست، اما بروز یک حادثه عمده یا انفجار،خسارات جبران ناپذیری را به موقعیت کارخانه و احتمالا کل این صنعت وارد می کند. از سال 1950 به بعد بحث مدیریت ایمنی و ارزیابی و شناسایی مخاطرات اهمیت ویژه ای پیدا کرد و به تدریج جایگاه خود را در صنایع فرآیندی مستحکم ساخت...
