The present investigation was undertaken with a view to develop a fast dissolving tablet of Metoprolol Tartrate which offers a new range of product having desired characteristics and intended benefits prepared by direct compression methodusing different concentrations of superdisintegrant. In the present work Fast dissolving tablets of metoprolol tartrate were prepared by direct compression super disintegrants such as sodium starch glycolate, croscarmellose sodium and crospovidone. All the tablets of metoprolol tartrate were subjected to weight variation, hardness, friability, in vitro dispersion, drug polymer interaction, drug content uniformity, and in vitro drug release The drug release from tablets of metoprolol tartrate prepared by direct compression was found to be 97.20% of D1 drug release within 10 minute. It is concluded that Metoprolol Tartrate fast dissolving tablets could be prepared using superdisintegrant with improved bioavailability and rapid onset of action.

An uncommon case has been reported of bilateral transscaphoid-perilunate dislocation racture following trauma. A 21-year-old male with bilateral transscapholunate dislocation was treated by open reduction and internal fixation. The case was examined in detail, and compared to the findings in the literature; observations regarding fracture prognosis were also made. Two years post-surgery, the patient remained asymptomatic.

Avulsion fractures of the tibial tuberosity are uncommon. There occur in well-developed, muscular athletic male individuals nearing skeletal maturity. The authors present a case of an 15-year-old boy who has a type IIB avulsion-fracture of the tibial tubercle. Surgical treatment gives an excellent outcome. We compare it with the literature.

The purpose of this study was to examine gender and age differences in computer usage, competence, attitudes, self-efficacy, and anxiety among teachers. Four hundred and sixty five teachers (223 females and 242 males aged 20 to 50 years) from twenty rural schools in south Jordan participated in the study. The data for the study were collected through the use of quantitative method. The results illustrated some gender and age differences in computer use, competence, attitudes, self-efficacy, and anxiety. However, the differences in computer use between male and female teachers are not similar. Males’ teachers typically had higher scores than females’ teachers in the use of computer for educational purposes. In addition, males’ teachers tend to have higher levels of computer self-efficacy and computer competence than females’ teachers. Likewise, both genders exhibited the same levels of attitudes towards computer use. Females’ teachers seem to have higher levels of computer anxiety than males’ teachers do. Finally, general age differences in computer use, competence, attitudes, self-efficacy, and anxiety among teachers were also found. The outcomes confirm the findings of other studies conducted in different educational settings regarding teachers’ gender and age differences in computer use, competence, attitudes, self-efficacy, and anxiety. Consequently, implications of the study give valuable insight to the future use of computers in schools. Recommendations were made based on findings.

This paper investigated gender balance and the Generative Instructional Strategy (GIS) on students’ achievement in reading comprehension in senior secondary schools in Ekiti State. 120 randomly selected students in Ekiti State public secondary schools participated in the study. The quasi-experimental design was adopted in the study. For pre-test and post-test, the same comprehension passages were administered. Data was collected through the use of the research instrument titled Reading Comprehension Achievement Test (RCAT). Two hypotheses were formulated and tested at 0.05 level of significance. Collected data were analysed using t-test. The study revealed that there was no significant effect of gender on the achievement of students exposed to Generative Instructional Strategy in reading comprehension. It was therefore recommended that Generative Instructional Strategy be adopted by English language teachers in Ekiti State and used in the teaching and learning of reading comprehension in the classroom.

Dipotassium sodium tetraborate octahydrate- K2Na[B4O5(OH)4]2 .8H2O (KNB) is an intriguing crystal for laser frequency conversion. It was grown by slow evaporation solution growth technique at ambient temperature. The investigated crystal is crystallized into noncentrosymmetric orthorhombic axial P212121 space group. Fundamental optical phonon modes were identified and the assignments were proposed.The dependence of second order optical susceptibilities with the applied d.c field strength for two principal geometries was studied. Piezooptical coefficients for the diagonal Pxxxx and off-diagonal Pxxzz tensor components under applied dc-field also were measured and discussed. Correlation between the anisotropy of the obtained spectra and of the observed nonlinear optical susceptibilities was established.

A new centrosymmetric semi organic crystal of 2-amino pyridine potassium chloride (2-APKC) was grown by slow evaporation solution growth technique at room temperature for the first time. Powder XRD study reveals the crystalline natures of the grown sample. Single crystal XRD study shows that the grown crystal is cubic systems of a= b= c= 6.19 Å; and ? = ? = ? = 90? with cell volume 237Å3. FTIR spectral study identifies the chemical composition and their corresponding functional groups of the grown crystal 2-APKC. UV–visible NIR spectral study confirms the absorption band in the range 250-800 nm with lower cutoff wave length at 320 nm. Thermal, dielectric and photoconductivity studies of grown crystals were done and discussed. SHG efficiency of the as-grown centrosymmetric crystal is confirmed first time by the Kurtz powder technique.

In today's world is a world organization, human resources as the most valuable corporate resources, and activities-based approach and promote organizational goals and ideals of the organization plays a major role. If people want to have a role in this new challenge, namely the process unless you have no way to wisdom and intelligence role in the development of our society are full of ideas (Mosheim, 2006). If this capability is known as a lifesaving tool in the management has emerged as one of the most important issues has become a day that can guarantee the success of organizations Philosophy, states that the capacity of the land and its people, but what needs to be Ordain the range is the range (Scott and Shah, 1996) A number of researchers trying to understand the factors affecting, stressed the importance of climate and culture of empowerment as conditions have been successfully.

Different types of soil samples have been collected from the specific area of the Gujarat state like Ahmedabad, Surat and Ghandhidham. In this work, mixed soil samples were prepared and Study of hydraulic conductivity has been measured with distilled water.

Abstract Matrix metalloproteinases (MMPs) are a family of structurally related proteins that degrade most if not all components of the extracellular matrix and basement membranes in a zinc dependent manner at a physiological PH. Cadmium is one of environmental pollutants arising from electroplating, fertilizers, pigment and plastic manufactures, most animals with scrotal testes are susceptible to cadmium–induced testicular toxicity. In this sense, This study conducted to investigate the effect of cadmium chloride (CdCl2) injection with different dose on the quantitative expression of MMP-2 and immunohistochemistry of male rats testes. 30 male Wister rats were conducted in this study , control group received saline IP (n = 10), CdCl2 treated group (n=10) were injected IP with of 5 mg/kg B.W., the third group (n= 10) which injected IP of CdCl2 in dose 10 mg / kg BW. The injections were twice per week continued for 3 weeks. The animals were euthanized and testicular tissues were collected and used for RNA extraction and real time PCR for quantitative expression of MMP-2 and immunohistochemical demonstration. We have found MMP-2 in control groups expressed in the leydig cells and sertoli cells and different stages of spermatogenesis. After injection of CdCl2 (5mg) of male rats showed decrease the quantity and expression of MMP-2 in the testicular tissue P<0.05 compare with control group, the group injected with (10mg) CdCl2 recorded more decrease of MMP-2 expression (P<0.01). In conclusion, our results highlight that cadmium directly cause reduction the quantity of MMP-2 in the testes without induced any inflammation in testicular tissue, the reduction of MMP-2 interfere with down regulation of reproductive activity that may lead to infertility due to environmental exposure to toxic metals of male.
