A Numerical Method for Nonlinear Singularly Perturbed Multi-Point Boundary Value Problem

引用

Journal of Applied Mathematics and Physics 2016年第6期4卷 1143-1156页

作者： Musa Çakır Derya Arslan Department of Mathematics Faculty of Science University of Yuzuncu Yil Van Turkey

We consider a uniform finite difference method for nonlinear singularly perturbed multi-point boundary value problem on Shishkin mesh. The problem is discretized using integral identities, interpolating quadrature rules, exponential basis functions and remainder terms in integral form. We show that this method is the first order convergent in the discrete maximum norm for original problem (independent of the perturbation parameter ε). To illustrate the theoretical results, we solve test problem and we also give the error distributions in the solution in Table 1 and Figures 1-3.

Objective: To investigate the effects of perorally administered juice on tetrachloromethane(CCl4)-induced hepatotoxicity model in rats. Methods: Male Wistar rats were tubeadministrated silymarin, Ecballium juice at 0.2 mL/kg and 0.7 mL/kg daily for 3 consequent days, ie. 3.28 μg and 11.48 μg of cucurbitacin B per kg of body weight respectively. On the third day, liver damage was induced by intraperitoneal application of CCl4. On the fourth day, abdominal cavity was macroscopically examined and liver samples were taken for histopathological and immunochemical evaluation. HPLC was used to determine the content of the active substance cucurbitacin B. Results: The experiment revealed that 0.7 ml/kg juice concentration expressed the highest pro-apoptotic activity, but with prevailing negative effects. Compared with the lower concentration, there was an observable vasodilatation with consequent interstitial hemorrhages and a larger scope of inflammatory damage, which suppressed the hepatoprotective effect. In the 0.2 mL/kg concentration, there was a smaller pro-apoptotic activity but other parameters had better results, and the liver parenchyma damage was reversible. Conclusions: No reactions confirming the potentially allergic effect on laboratory rats were observed; its hepatoprotective and anti-inflammatory effect was confirmed on a model of acute liver damage.

Advances in Microbiology 2016年第14期6卷 999-1009页

作者： Mutlu B. Güler-akın Ismet Ferliarslan Musa Serdar akın Department of Food Engineering Agricultural Faculty Harran University Sanliurfa Turkey

In this study, the effects of different amounts of inulin and oat fiber addition on the properties of apricot probiotic drinking yoghurt (APDY) were investigated. Seven different APDY was produced. Six of them were produced by the addition of 0.5%, 1% and 2% inulin (B, C, D) and oat fiber (E, F, G) and one of them was produced as control sample. Pasteurized apricot pureed and sugar (10%) was added to fermented milk beverage. APDYs were analysed 1, 7, 14 and 21 days after production. Addition of fiber to APDYs had significantly affected on the pH, titratable acidity, water holding capacity, S. thermophilus, L. acidophilus Bifidobacterium BB-12 counts, and sensorial properties of the samples (p L. acidophilus and Bifidobacterium BB-12 counts increase by the addition of fiber into samples.

Role of Ultrasonography in Evaluation of Peripheral Nerves

引用

Open Journal of Internal Medicine 2018年第4期8卷 232-247页

作者： Mandugula Aruna Devi ak Meena Department of Radiology Nizam’s Institute of Medical Sciences Hyderabad India Department of Neurology Nizam’s Institute of Medical Sciences Hyderabad India

Ultrasonography is first line, cost-effective modality in imaging of peripheral nerves. High frequency probes allow high resolution imaging of peripheral nerves located at relatively superficial location. USG can diagnose and localize various pathologies that involve the peripheral nerves such as traumatic, inflammatory, infective, neoplastic, and traumatic neuropathies. USG exceptionally has an important role to play in evaluation of patients with suspected nerve injury, as MRI may not differentiate neural contusion from nerve disruption. Neurapraxic injury is seen as swollen nerve with hypoechoic appearance.

Use of Borax Sludge as an Additive in Wall Tile

引用

Journal of Materials Science and Chemical Engineering 2016年第12期4卷 39-45页

作者： Mine Özdemir İlker Kıpçak Department of Chemical Engineering Eskisehir Osmangazi University Eskisehir Turkey

In this research, the use of borax sludge, which is generated in borax industry, as an additive in wall tile, was investigated. The wall tile samples were prepared by adding boron waste to the wall tile composition in the range of 2% - 10%. The effect of boron waste on the physical and mechanical properties of wall tile was determined. The results obtained were compared with the control tile and Turkish Standards (TS). The boron waste addition up to 8 wt.% was found to improve the water absorption and strength of wall tile.
