Objective: This study aimed to investigate the possible anti angiogenic activity of Vitex agnus castus leaves extracts Methods: The leaves were dried and grounded into fine powder, and extracted sequentially with Chloroform, methanol and water. Ex-vivo rat aorta anti angiogenic assay was used to identify the most anti angiogenic extract, active extract has been chosen for dose response testing, by preparing serial concentrations of that extract and applied on aorta rings of the rat, the active extract was tested on human umbilical ventricular endothelial cell line as in vitro assay. Free radical scavenging activity has been tested by 1,1-Diphenyl-2-picrylhydrazyl (DPPH) to discover which extract has the highest free radical scavenging activity and as a mean to elucidate the possible mechanism of extract action. Results: Methanol extract has the highest percentage of blood vessels growth inhibition in comparison to other extracts P< 0. 05. However, there were no significant differences between chloroform and water extract P> 0. 05. Methanol extract showed dose dependant inhibitory activity on rat aorta assay the IC50 was (21.73 μg/ml). Methanol extract showed dose response activity against human umbilical ventricular endothelial cells (HUVEC) and IC50 was (42.09μg/ml). Methanol extract of Vitex agnus castus leaves showed the most potent free radical scavenging activity in comparison to other extracts; IC50 was (126.79μg/ml). Conclusion: The results showed that methanol extract of Vitex agnus castus has potential anti angiogenic activity and this activity may be due to the high activity in free radical scavenging capability.

In this paper was developed a dynamic model of multipath routing based on balancing lengths of queues at the routers of telecommunication network represented by a system of linear differential equations of queue buffer utilization. The novelty of represented model is a modification of the conditions of balancing lengths of queues to take into account the priorities and lengths of packets in queues. Proposed model allowed to convert the solution of multipath routing based on balancing lengths of queues to solution of problem of optimal control. Using the solution proposed allows to organize a more effective control of buffer and link network resources due to the consistent solving of multipath routing and balancing lengths of queues problems in accordance with the concept Traffic Engineering Queues. © 2015 Kharkiv National University of Radioelectronics.

Solution of actual scientific and practical problem associated with the development of flow-based model of multipath routing with traffic policing rejection balancing was presented. Within the proposed model consistent solution of problem of multipath routing with traffic policing rejection balancing converged to solution of optimization problem of linear programming with the optimality criterion as minimum of dynamically managed upper bound of rejections for all flows in a whole network. Numerical examples of multipath routing with traffic policing rejection balancing problem solving confirmed the adequacy and effectiveness of the proposed solution. Investigation of processes of multipath routing with traffic policing rejection balancing using the proposed model showed that the flow rate restriction on the network edge has an adaptive nature. © 2015 Kharkiv National University of Radioelectronics.

In this paper, the optimization of a nanofluid-cooled microchannel heat sink was reported. Al2O3-NH3 with three different volume fractions (1 %, 3 % and 5 %) was examined. An optimization scheme which is comprised of two objective functions (thermal resistance and pumping power) and the elitist non-dominated sorting genetic algorithm (NSGA-II) was employed to optimize the overall performance of the considered system. Under the same operating conditions, the ammonia-base nanofluid (Al2O3-NH3) exceeded other coolants (Al2O3-H2O and H2O) in terms of the required pumping power (0.144, 1.015 and 0.94 W for Al2O3-NH3, Al2O3-H2O and H2O, respectively). When the refrigerant base nanofluid is used as a cooling fluid, a lighter heat sink was produced. Finally, more studies should be dedicated to explore this nanofluid and the possibility of considering it for electronic systems cooling. © 2013 Praise Worthy Prize S.r.l. - All rights reserved.

Arabic language is a unique language because of its pronunciation of the word written. The formation of more than two Arabic letters will translate to a different meaning. This paper presents an alternative translator from Arabic word to English word by using an equation for the formation of the Arabic letters. The morphological model of Arabic language is used in order to use the equation to put diacritics according to Arabic grammatical rules. A system is then developed based on the morphological model. The input of the system is the Arabic word. The system uses morphological Arabic Natural Language Processing (ANLP) and translates the Arabic word into English word. The output of the system shows percentage of the successful translated words. We tested our system by using 11 Arabic words. The results show that 9 out of 11 Arabic words (81.81%) were successfully translated by conducting the process of diacritics in the morphological model of Arabic language. We also perform a quality assessment to calculate the efficiency and effectiveness metrics based on the ANLP developed. Based on the result, the system can be used as an alternative translator from Arabic word to English word. © 2015 IEEE.
