A defuzzification approach to solve a multi-objective programming problem with fuzzy parameters

Abstract: The multi-objective programming problem with fuzzy parameters can be solved by interval programming (IVP) approach which produces the optimal solutions in interval form. However, this paper presents new insights of solving the same problem by a defuzzification approach that is able to produce specific optimal solutions. In the proposed defuzzification approach, the linear programming model is used as an approximation technique to defuzzify fuzzy numbers in the objectives and constraints. In the model formulation, the interval of fuzzy numbers is employed to convert the problem into the standard goal programming problem. As a result, specific optimal solutions of the objective functions are obtained in the specified intervals instead of only in form of intervals as the final solutions. A numerical example is used to illustrate the proposed approach.

Bioorganic investigation of encapsulated Cysteine derivative into polymeric nanocarrier

Abstract: In this work, the copolymer-based synthesized Cysteine-loaded nanocarriers prepared by a routine protocol, coprecipitation method. It is the first report to investigate the neuroprotective potential and biocompatibility of Cysteine derivatives loaded into poly(ethylene glycol)-block-poly(e−caprolactone) methyl ether (PEG-b-PCL). The average size of the polymeric/empty NCs was 89 nm and for polymeric/Synthesized derivative of Cysteine was 126 nm. The Drug Loading efficiency was 81%. The concentration of Polymeric NCs was 2.1 x 10 10 particles/ml and the zeta potential of polymeric/empty and polymeric/ Synthesized derivative of Cysteine NCs -5 mV and -11 mV respectively. Biological part of this work were investigated in the SH-SY5Y human neuroblastoma cell line using cell viability and toxicity assays. The concentration of polymeric NCs below 1 x 10 10 particles/ml described as a zero-point damageable for the cell line. Also the Synthesized derivative of Cysteine encapsulated into polymeric NCs have more neuroprotective effect compared to free Cysteine at lower concentration, and therefore, have a significant neuroprotective potential against Z-VAD-fmk and St-evoked SH-SY5Y cell damage.

Effect of arginine and selenium with vitamin E in some biochemical properties of Inseminated ewes

Abstract: The study was conducted in one of the fields of the private sector within Basaaer the village of the district of Hit / Anbar at 180 km west of Baghdad, during the period from 17/4/2018 to 30/5/2018. 28 ewes with an age of 2-4 years with a weight of 40-50 kg with at least one birth. All ewes were tested using ultrasonography to ensure that they were free of pregnancy before the start of the experiment. Synchronization of estrus with intravaginal sponges was achieved in ewes, and inseminated with rams at the end of the hormonal program. The rams remained with the females for five days. The ewes were randomly divided into four equal groups (7 ewes in each group). The first group were injected with 160 micro mol / kg body weight and from the fifth day of the inseminated until day 20 of pregnancy The second group was treated by injecting selenium plus vitamin E with (2 ml/head α-Tocopheryl Acetate 68mg/ml Selenium 1.5mg/ml) intramuscular. The first dose was given on day 5 and the second one on day 19 of insemination the early at pregnancy. The third group were injected the arginine with the selenium plus vitamin E emulsion, The fourth group was injected with a physiological saline solution and considered as control group. Blood samples were collected from jugular vein prior to treatment on day 4 of the insemination as well as on days 10, 15, and 18, to measure the changes in the chemical properties at the early of pregnancy. The results of the study showed a significant difference (P≤0.05) between the treatments and control groups. The results showed a decrease in the concentration of urea and ALT enzyme as compared with the first group and control. The present study did not show a significant differences at early of pregnancy in the concentration of cholesterol, total protein, albumin, globulin, glucose, and AST enzyme at the early of pregnancy for ewes. The results also showed a significant difference (P≤0.05) between the different withdrawal periods within the same treatment in the control and other groups the concentration of ALT enzyme, and total protein. It can be concluded from this study that the use of arginine and selenium with vitamin E improves maternal health by reducing the level of urea and ALT enzyme and maintaining pregnancy after insemination.

Evaluating of Tissue Germination and Growth Rate of ROI on Implants of Electron Scanning Microscopy Images

Abstract: The emerging field of in cancer pathology (computational pathology) using histological images of biopsies is a computer aided diagnosis. This paper devoted to computational methods for assessing the indicators of the process of tissue regeneration with the release of nickel-mesh reticulated titanium implants with shape memory. Accordingly, in order to design such computer-aided system that is able to measure the implants size and growth rate, this paper presents a computational toolkit. Moreover, this toolkit used to analyze the dynamics of the process and highlight the internal geometric features of the experimental images (segmentation algorithms and visualization of spatial data). The computational tools for preprocessing visual data is the important concept solution to increase the contrast and brightness of the analyzed images based on the Contrast Limited Adaptive Histogram Equalization (CLAHE). Finally, the result of proposed technique shows that the increasing the accuracy of estimates for testing data through (15-20%).
