Gaza, Palestine

The Islamic University of Gaza , also known as IUG, IU Gaza and The University of Gaza, is an independent Palestinian university established in 1978 in Gaza City, Palestinian territories. The university, according to its website, has 10 faculties capable of awarding B.A., B.Sc., M.A., and M.Sc. diplomas and higher diplomas in their respective disciplines. The Islamic University of Gaza is a member of four regional and international associations of higher education, which are the International Association of Universities, the Community of Mediterranean Universities, the Association of Arab Universities and the Association of Islamic Universities. As of August 2014, due to the 2014 Israel-Gaza conflict, Israeli forces have destroyed the Islamic University of Gaza by firing multiple missiles into the building. People were reported to be inside the university campus during the attack. A large part of the university has been destroyed. No casualties were reported in the strike. Wikipedia.

The ligands 2-acetylbenzimidazole benzoylhydrazone (HBBH) and 2-acetylbenzimidazole isonicotinoylhydrazone (HBIH) were prepared and characterized by elemental analysis, IR, NMR, and mass spectra. The complexes of these ligands with Co(II), Ni(II), Cu(II), and Zn(II) were prepared by the reaction of methanolic acetate salts with the ligands in methanol in a 1:2 metal:ligand mole ratio. M(II)L 2 were characterized based on elemental analysis, IR, NMR, MS, conductance, and electronic spectral measurements. Co(BBH) 2 and Ni(BIH) 2 were crystallographically characterized. They consist of two ligands that give six coordinate bonding to Co(II) and Ni(II) on a meridional plane through benzimidazole ring nitrogen, azomethine nitrogen, and benzoyl or isonicotinoyl oxygen, respectively. Co(BBH) 2 crystallizes in the triclinic space group P and Z=2 at 150K with a=9.9010(3), b=9.9705(4), c=15.8141(6), =96.424(2), =94.1580(10), and =92.153(2). Ni(BBH) 2 crystallizes in the monoclinic space group P 21/n and Z=4 at 100K with a=14.3156(2), b=24.7402(4), c=19.8215(3), =90, =98.7761(7), and =90. The metal centers in these complexes have two ligands in a meridional, slightly distorted octahedron. © 2012 Copyright Taylor and Francis Group, LLC. Source

In this paper, surface waves excited at the interface between left-handed and right-handed materials are employed for sensing applications. The propagation of p-polarized (TM) surface waves in a three-layer slab waveguide structure with air core layer as an analyte and anisotropic left-handed materials as claddings is investigated for detection of any changes in the refractive index of the analyte. The dispersion equations and the sensitivity of the effective refractive index to any change in the air layer index are derived, plotted, and discussed in details. The field profile is also explored. It is found that the sensitivity of the proposed surface wave sensor is almost independent of the wavelength of the propagating wave. A considerable sensitivity improvement can be obtained with the increase of transverse components of the left-handed material permittivity. © Elsevier B.V. All rights reserved. Source

A three-layer slab waveguide with air core layer and anisotropic left-handed material claddings is investigated for sensing applications. Different from the waveguide mode sensors and surface plasmon resonance sensors in which the analyte is placed in the evanescent field region, the proposed sensor contains the sample in the core region that supports the oscillating field. Due to the strong concentration of the electromagnetic field in the analyte medium, the proposed device exhibits unusual sensitivity enhancement. The simulations revealed that the sensitivity improvement of TE3 mode compared to conventional evanescent wave sensor is approximately a factor of 20. © 2014, Versita Warsaw and Springer-Verlag Wien.

Some new metal(II) complexes, ML2 [M=Co, Ni, Cu and Zn], of 2-acetylthiophene benzoylhydrazone ligand (HL) containing a trifunctional SNO-donor system have been synthesized and characterized on the basis of physicochemical data by elemental analysis, magnetic moment, molar conductance, thermogravimetric and spectroscopic (electronic, IR, 1H NMR and 13C NMR) data. The ligand functions as monobasic SNO tridentates where the deprotonated enolic form is preferred in the coordination producing distorted octahedral complexes. © 2010. Source

Usability is critical for any system, but in software it is one of the most important features. In fact, one of the main reasons for software failure is the system lacking to achieve users specified goals and satisfaction. For this reason, usability evaluation is becoming an important part of software development. Software usability evaluation can be costly in terms of time and human. Therefore, automation is promising way to augment existing approaches especially if the evaluation is subjective where the usability concentrated about user's "opinion". This paper proposes to use opinion mining as an automatic technique to evaluate subjective usability. Opinion mining is a research subtopic of data mining aiming to automatically obtain useful opinioned knowledge in subjective texts. We propose a novel model to extract knowledge from opinions to improve subjective software usability. This is the first time opinion mining used in software usability. To evaluate our proposed model, a set of experiments was designed and conducted and we got an average accuracy of 85.41%. Also, we propose to use graphics to visualize user's opinion in software and to compare the usability of two software. © 2014 ACADEMY PUBLISHER. Source
