Osteoarthritis (OA) is the most common musculoskeletal disorder worldwide. Knee and hip joints are most commonly affected by OA, and their impact on public health is remarkable. The effects of OA on an individual are also considerable. The symptoms of OA, such as pain and stiffness of the joints and muscle weakness, are serious risk factors for mobility limitation and impaired quality of life. Osteoarthritis begins in the cartilage and eventually leads to the two opposing bones eroding into each other. Laboratory tests (using X-rays) for rheumatologic problems lack the sensitivity and specificity to allow their use as screening tools. Diagnosis is the critical challenge in MEMS research. This paper deals with the design of capacitive comb drive sensor for diagnosing joint-cartilage disorder including the degradation of joints and inflammation. The comparison between various stages of osteoarthritis leads to the diagnosis

We report a case of Fisher/guillainbarré overlap in a 14 years old patient with antecedent of an infectious respiratory event one week before the installation of Miller fisher Syndrome. The symptomatology rapidly evolved into a case of guillainbarré with respiratory and deglutition disorders. The patient received 2 courses of IvIg, 5 days each, with a 2 weeks interval which resulted in a total decline of paralysis and motor recovery. This case shows the importance of meticulous surveillance of patients with Miller Fisher syndrome in order to act on first symptoms of a guillainbarré overlap.

In this paper we present a new method to compute the determinants of matrices of order 4. This method computes the determinant of matrices of order 4 by using the schemes.

Condensation of ethyl acetoacetate 2 with thiosemicarbazide 1a gave hydrazone derivative 4 not pyrazolone 5. Pyrazolone 5 can be obtained by treatment of 4 with 5 % sodium hydroxide in ethanol. Reactions of 4 with phencyl bromide, aryl diazonium chloride , arylidene malononitrile afforded pyrazole derivatives 6, 7 and pyranopyrazole 8 respectively. Also, treatment of 4 with dimethylformamide dimethyl acetal (DMFDMA) gave compound 11 not 9 nor 10. Reactions of pyrazole derivatives 6 with arylidene malononitrile afforded condensed compound 15 which was obtained by reaction with aromatic aldehydes. While reaction of 6 with DMFDMA gave the corresponding enamine 16.

In recent years, marine oil pollution resulting from exploitation spills and accidents during oil transportation and use has affected the marine ecosystem safety, and oil polluted sea water remediation becomes a global problem. Peanut shell possesses a good property of adsorption pollutants and it can be easily obtained from the abundant produce of peanut all around the world. This experiment used carbonized peanut shell (CPS) as adsorbent; aiming to purify oil polluted sea water and explore optimal adsorption conditions and effects. Six sets of experiments were done under the initial oil concentration of 1.35 mg/L and CPS dosages of 0, 6.67, 13.33, 20, 26.67, 33.33 g/l, separately. Seventy percent of oil was removed under the ideal dosage of 13.33 g/l, getting the minimum oil concentration of 0.39 mg/l. Another six sets of experiments were also done under the adsorption time of 0 h, 1 h, 2 h, 3 h, 4 h, 5 hand the same CPS dosage of 13.33 mg/l. The ideal removals of Chemical Oxygen Demand (COD) (35.5%) and oil (71%) were obtained after 3 hours adsorption, while the highest COD removal gets to 47.5%.

Crystals of potassium hydrogen phthalate (KAP), a semi-organic compound, have been grown by slow evaporation method at room temperature from aqueous solution in the presence of mono valent metal ionic impurities Ag+, Li+ and Na+. Elemental analysis by inductively coupled plasma optical emission spectroscopy (ICP-OES) proves the incorporation of these impurities into the grown crystals. Powder X-ray diffraction studies confirmed the phase formation and metal ions doping into KAP crystals. Thermo gravimetric analysis (TGA) show the onset decomposition temperatures to be 255, 258, 238 and 272°C for pure and Ag+, Li+ and Na+ doped KAP crystals respectively. Microhardness studies revealed that Na-KAP crystals have higher hardness values than all the doped crystal. All the crystal exhibited the second harmonic generation (SHG) conversion efficiency. The grown crystals were also subjected to Fourier transform infrared (FTIR) spectroscopy, UV-Vis spectroscopy studies and dielectric studies. Among the three investigated metal ion impurities, Na+ ion seem to have positive influence on the growth, mechanical, thermal, dielectric and SHG characteristics of KAP which makes it suitable for limited level of applications.

In the present era of globalization with increased opportunities and easy and free movement of workforce, companies are striving hard to retain their employees to get the best out of them. It is considered that a committed workforce is an asset to the organization. What are the factors which influence employees’ commitment towards organization is a much debated aspect in the management field. A good number of literatures on organizational commitment opine that organizational commitment is a psychological attachment of the members of an organization including a sense of job involvement, loyalty and belief in the values of the organization. On the other hand it indicates that a committed employee is one who accepts the organizational goals and willing to exert effort on behalf of the organization. An employee, who is affectively committed, strongly identifies with the goals of the organization and desires to remain the part of the organization. This study makes an effort to analyse the relationship between the behavioral aspects of the employees such as performance, loyalty, satisfaction with the organizational commitment as well as the relationship between the behavioral aspects with the personal attributes such as age, gender, position and length of service. The study reveals that there is a strong positive relation between the organizational commitment and performance, loyalty and satisfaction while there is no significant relationship between the behavioral aspects and the personal attributes.

In-service training of teaches is a systematic process and wide infrastructure that requires extensive communication to execute any program in order to ensure maximum involvement of all those who are associated with educational enterprise, one or the other way like teachers, administrators, curriculum-developers, research workers, teacher trainers, specialists, etc. In-service training programs actually provide an opportunity to those who are trained but in experienced. This type of training facilitates professional learning and helps teachers to abreast themselves with the upcoming knowledge, educational developments and innovations but unfortunately there are numerous problems that interrupt when these programs are intended to commence. So in order to overcome expected problem, a model has been suggested in this article that will conducive for resolving problems of in-service teacher training and it will provide an insight in order to certify successful and more beneficial planning of such programs. Improvement in any education system can only be made when teachers are given upmost priority and their in-service training is considered mandatory in order to meet new challenges. In brief to deal with modern challenges, teachers’ professional development or in service training is imperative, as said by John Cotton Dana: “Who dares to teach must never cease to learn”.

This study performed to programs presentation for environmental management of Maharloo Lake by SWOT method. This lake with an area of 600 sq.km is located 27 km southeast of Shiraz. The lake water is used for extraction of normal salt. It is considered a suitable and valuable habitat for migratory birds and wild animals. Environmental management processes include 4 steps. In order to gather information about the area, some method employment included: the Department of the Environment of the province, indigenous publications, library, Internet and questionnaires. The main purpose of SWOT analysis is to identify those internal and external factors in achieving the goals and those are important. In this method, information divided in two categories, 1: Internal factors, including strengths and weaknesses, which can be identified by internal factors matrix. 2: external factors including Opportunities and threats for environment, those factors can be identified by the external factors matrix. According to SOWT strategies, we designed best strategies regional management of Maharloo Lake.

Quantum chemical calculations offer the real promise of being able to complement experiment as a means to uncover and explore new areas in chemistry. One of such is its use in the determination of molecular structure, kinetics and reactivity. This work seeks to investigate the molecular properties of Oxygen monofluoride (OF) and its two possible protonated analogues (HOF+ and HFO+). Quantum chemical methods; Hartree fock (HF), Becke-3-Lee-Yang-Parr (B3LYP), Moller-Plesset second order (MP2), Coupled Cluster method (CCSD) and Gaussian 04 method (G4) with varying basis sets were employed in the determination of the parameters (Dipole moment, bond distance, IR frequency, zero point vibrational energy, and rotational constants) reported for the three molecular species studied in this work. Bond angle was reported for the two protonated analogues (HOF+ and HFO+). From the results as compared to the experimental values, B3LYP/6-311++G** method proves itself as the best method in the optimization and frequencies calculations of the OF, HOF+ and HFO+ because it gives better accuracy in most of the calculated parameters and the MP2 method also give relative accuracy in some of the calculated parameters of OF and its protonated analogues, HOF+ and HFO+. The optimized geometry shows the OF molecule to be linear while the protonated analogues were non-linear.
