Relevance. The efficiency of agricultural production largely depends on the technical condition machinery fleet. condition, in turn, many factors that determine level operation equipment. One most important determining reliability machinery, cost restoring and maintaining working is frequency maintenance. As a result studies conducted organizations region, it was revealed engineering services, ...

The work was created in the framework of the research project B141180000050.03 “Alcohol craving in alcohol-dependent people. Polish adaptation of measuring tools and their distribution” (“Odczuwanie głodu alkoholu przez osoby uzależnione. Polska adaptacja narzędzi pomiaru i ich upowszechnienie”), financed by the State Agency for the Prevention of Alcohol-Related Problems. Validation of the Poli...

افزایش فسفر معدنی در محیط های آبی باعث کاهش کیفیت آب ها شده و ایجاد پدیده یوتریفیکاسیون را سرعت می بخشد. به منظور بررسی کارایی حذف فسفر توسط نانواکسیدهای آلومینیوم و آهن، آزمایشی به صورت بچ (batch) با غلظت اولیه فسفر (0-60 میلی گرم در لیتر) در 3 سطحph (4، 7، 10) با 1/0 گرم از نانواکسیدآلومینیوم و نانواکسیدآهن در قدرت یونی ثابت (kcl 0.01m) انجام گردید و همچنین در ph ثابت 7 با قدرت های یونی مختلف...

The proposed digital system consists of several different modules that can be divided into three main groups: input modules, audio output modules, and video output modules. All of these modules will be clocked off a 27MHz clock signal provided by the 6.111 Labkit. The system’s input comes from an analog signal produced by a pedometer, and it is then processed by the input modules to produce rel...

Threshold Implementation (TI) is an elegant and promising lightweight countermeasure for hardware implementations to resist first order Differential Power Analysis (DPA) in the presence of glitches. Unfortunately, in its most efficient version with only three shares, it can only be applied to 50% of all 4-bit S-boxes so far. In this paper, we introduce a new approach, called factorization, that...

We study the rational Cherednik algebra Hc of type G(r, 1, n) by means of the Dunkl-Opdam operators introduced in [DuOp] and the generalized Jack polynomials introduced in [Gri]. Our main result is a characterization of the set of parameters c for which Hce+Hc 6= Hc, where e+ is the symmetrizing idempotent for G(r, 1, n). Such parameters are called aspherical. The proof is parallel to that in [...

tau is one of several types of microtubule-associated proteins (maps), responsible for the assembly and stability of microtubule networks that is present only in neurons and predominantly localized in axons which its functions are tightly regulated by phosphorylation. via as yet unknown mechanisms, tau becomes hyperphosphorylated and accompanies with neuronal degeneration, loss of synapses, abe...
