This study was carried out to determine the breeding practices, important income sources and future of water buffalo farming in Çaycuma district Zonguldak province. For this purposes, 36 breeders were determined from villages constitute population region. It is predicted that these different parts will reveal current situation have sufficient material for this. First all, a survey conducted wit...
Adolescent idiopathic scoliosis (AIS) is a clinically significant disorder with high heritability that affects 2-4% of the population. Genome-wide association studies have identified LBX1 as a strong susceptibility locus for AIS in Asian and Caucasian populations. Here we further dissect the genetic association with AIS in a Caucasian population. To identify genetic markers associated with AIS ...
To determine the non-bonded interaction energies between Naphthalene and B12N12 Nano ring in different orientations and distances, geometry of molecules with B3LYP method and 6-31g* basis set optimized. Also reactivity and stability of Naphthalene alone and in the presence B12N12 Nano ring checked. Then calculated the NBO, NMR, FREQ, NICS and muliken charge of Naphthalene atoms alone and in the...
To determine the non-bonded interaction between methyl benzoate and boron nitridenanotube, we focused on an armchair single-wall boron nitride nanotube (9,9) With length 5 angstroms.The geometry of molecules was optimized using B3LYP method with 6-31g* basis set. Also reactivityand stability of methyl benzoate and boron nitride nanotube (9,9) was checked. Then NBO, FREQ,...

Quaternary ammonium compounds (QACS) are employed both as disinfectants for manual processing lines and surfaces in the food industry, and in human medicine area. QACS also cause cell death by protein denaturation . One of the QAC is cetyl trimethyl ammonium bromide (CTAB) that appears to rapture the cell membrane. The primary site of action of CTAB has been suggested to be the lipid components...
Statistical methods for automatically identifying de pendent word pairs i e dependent bigrams in a cor pus of natural language text have traditionally been performed using asymptotic tests of signi cance This paper suggests that Fisher s exact test is a more ap propriate test due to the skewed and sparse data sam ples typical of this problem Both theoretical and experimental comparisons between...
This paper proposes a nonlinear approach for designing traffic responsive and coordinated ramp control using a self adapting fuzzy system. The traffic responsive metering rate is determined every minute by an adaptive fuzzy logic algorithm. The coordination between multiple on-ramps is ensured by the integration of a common input into all ramp controllers upstream of a bottleneck and a periodic...
In the paper the problem of basic power system electric quantities (current, voltage magnitudes, power and impedance) measurement in off-nominal frequency conditions is considered under assumption thal the quantities are calculated from orthogonal components of input current and voltage phasors which are obtained by use of the nonrecursive digital Jilters. Adaptive algorithms which make the mea...
بکارگیری روشهایی برای پایش pH شکمبه و حفظ آن بین 5/5 تا 7 ضروریست. هدف از این پژوهش، ساخت یک نانوحسگر pH مبتنی بر روش طیفسنجی امپدانس الکتروشیمیایی، EIS، بهمنظور استفاده در سامانه پایش pH شکمبه گاو میباشد. نانولولههای تکدیواره (SWNT) با گروههای کربوکسیل (COOH) و نیز، با گروههای آمین (NHRNH2) عاملدار شدند. الکترود شانهای با یک قطره از محلول حاصل از پخش یک نسبت معین از COOH-S...
