Effects of visual media in promoting of awareness of Palestine-Israel conflict : an Al-Aqsa satellite channel case study

Media has a significant effect on the human morals and customs, and forming public opinion towards cases and issues, such as the Palestinian Case. However, very few studies have addressed the impact of the visual media on the overall evaluation of the young leaders and their political views. Hence, the present study aimed at exploring the effect of the visual media on the overall evaluation of the young leaders, how they view politics at the first place, what sort of awareness has been resulted, and whether these young leaders have other medium to rely on for interaction with the outside world. The study also aimed at developing an understanding of how visual media generates interest about programs, the effect of the programs in Al-Aqsa Satellite Channel, and the effect of visual media on the awareness of the Palestinian – Israeli conflict among leaders of university students in the Arab countries. A qualitative research method was used to gather the data, adopting focus group to interview students’ leaders from many Arab countries, including Syria, Jordon, Lebanon and Egypt, as well as interviewing six seniors of Al-Aqsa Satellite Channel. The findings revealed that there is an impact of plans and policies management on the awareness of the Palestinian issue if there was a strategic adoption and content following by the institution. Second, content management has a significant impact in raising awareness, but it is divided into three levels: verifying in representation in an attractive format with considering time, discourse and repetition, and there is little impact on the need to make polls, periodical assessment and selection of displaying time. The findings also showed that money is the most important in all media work and it is the core factor in affecting since it affects planning, content and individuals and abilities. Results also revealed that there is disparity in participation in countries under the study depending on the country and its privacy

On-Shell Description of Unsteady Flames

The problem of non-perturbative description of unsteady premixed flames with arbitrary gas expansion is solved in the two-dimensional case. Considering the flame as a surface of discontinuity with arbitrary local burning rate and gas velocity jumps given on it, we show that the front dynamics can be determined without having to solve the flow equations in the bulk. On the basis of the Thomson circulation theorem, an implicit integral representation of the gas velocity downstream is constructed. It is then simplified by a successive stripping of the potential contributions to obtain an explicit expression for the vortex component near the flame front. We prove that the unknown potential component is left bounded and divergence-free by this procedure, and hence can be eliminated using the dispersion relation for its on-shell value (i.e., the value along the flame front). The resulting system of integro-differential equations relates the on-shell fuel velocity and the front position. As limiting cases, these equations contain all theoretical results on flame dynamics established so far, including the linear equation describing the Darrieus-Landau instability of planar flames, and the nonlinear Sivashinsky-Clavin equation for flames with weak gas expansion.Comment: 21 pages, 3 figures; extended discussion of causality, new references adde

A source of inspiration: ATC for visually impaired students at the Islamic University of Gaza

In the age driven by information technology, each university has a mission to equip its students with the necessary tools. The Islamic University of Gaza (IUG) offers all of its student access to the computing world and online classes. In order not to leave anyone behind, IUG established an Assistive Technology Center (ATC) for the visually impaired students. In this paper, the ATC is presented as a case study. The structure, resources, achievements, problems, future plans and project are displayed

The optical sensor mote, a novel device for enabling next generation Wireless Sensor Networks

Recent advances in micro-electronics and communications have fuelled research in Wireless Sensor Networks (WSNs). WSNs are a collection of low power, low cost, small form factor devices referred to as sensor motes interconnected in a random manner to establish a network. Despite wide ranging research into a range of applications, significant limitations stand in the way of utilizing WSNs to monitor large scale/area environments. Optical sensing techniques are well suited for monitoring a large variety of environmental variables such as temperature, pressure, humidity, and gas concentrations. However, traditional optical sensing techniques rely on bulky solutions including spectroscopic equipment and fibre based approaches. On the other hand, photonic crystals have caused a revolution in integrated optics as they allow functionalities not possible before; however little has been reported on their use as integrated optical sensors. The research work combines the diverse but related fields of WSNs, integrated optics, and Photonic Crystals. A novel platform, the optical sensor mote, is proposed and its key building blocks are experimentally demonstrated as a feasibility study. Specifically, multi-gas sensors based on the slow light phenomenon in photonic crystal waveguides are theoretically and experimentally demonstrated. These sensors can sense multiple gases without the need of any physical changes. They can also be integrated with electronics to yield an optical sensor mote of small form factor which is stable, multi-functional, and cost-effective. The optical sensor mote represents a significant step towards enabling the wide spread use of WSNs to monitor large scale/area environments and providing a highly integrated mote platform amenable to mass production and providing multi-functions.Recent advances in micro-electronics and communications have fuelled research in Wireless Sensor Networks (WSNs).

Docking Study to Predict the Efficacy of Phosphatidylinositol 3-Kinase α Inhibitors

The phosphatidylinositol 3-kinase (PI3K) family comprises lipid kinases that cross-link signals between living cells and their surroundings. PI3Ks are classified into several groups and isoforms with specific characteristics and functions. Genes encoding PI3Ks are mutated in several types of cancer, and their isoforms have varying capacity in promoting cell signaling and cancer progression. Many compounds have been introduced as PI3Kα inhibitors, but not all of them have the same inhibitory effects. For successful PI3K-related biomedical experiments, it is vital to select the most specific and potent compounds with the highest inhibitory effects for targeting this kinase. In this study, we investigate 28 well-recognized PI3Kα inhibitors through predicting their specificity and potency using the docking software AutoDock Vina. Our data showed that PF 05212384 had the highest docking score (−9.2 kcal/mol), and 3-methyladenine had the lowest docking score (−4.8 kcal/mol). Our data also showed different types of interactions and bonds formed between the inhibitors and protein residues. In conclusion, PF 05212384 and AZD 6482 compounds are the best candidates for targeting PI3Kα. In addition to hydrophobic interactions in the PI3Kα binding pocket, the formation of hydrogen bonds between these inhibitors and binding pocket residues was confirmed

Recent advances in numerical simulation and control of asymmetric flows around slender bodies

The problems of asymmetric flow around slender bodies and its control are formulated using the unsteady, compressible, thin-layer or full Navier-Stokes equations which are solved using an implicit, flux-difference splitting, finite-volume scheme. The problem is numerically simulated for both locally-conical and three-dimensional flows. The numerical applications include studies of the effects of relative incidence, Mach number and Reynolds number on the flow asymmetry. For the control of flow asymmetry, the numerical simulation cover passive and active control methods. For the passive control, the effectiveness of vertical fins placed in the leeward plane of geometric symmetry and side strakes with different orientations is studied. For the active control, the effectiveness of normal and tangential flow injection and surface heating and a combination of these methods is studied
