The purpose of this study was to investigate the influence of employee engagement on commitment in the county government of Kakamega in Kenya. The study adopted a descriptive research design with a target sample of 313 respondents drawn from a sampling comprising top management, middle management, and lower cadre employees in 12 sub counties within the county. The sampling frame was obtained by using stratified and simple random sampling techniques. From each stratum, a proportionate allocation was used to select a representative sample and the data collected by use of questionnaires. Data was analysed using descriptive, correlation and linear and multiple regression analyses. The findings obtained indicated that employee engagement had a positive and significant influence on commitment in Kakamega county government. Furthermore, the findings also revealed that vigour engagement has a higher positive and significant influence on employee commitment, with absorption giving the least influence on the predicted variable. The study recommend that county governments should endeavor to enhance engagements among their employees in order to ensure sustained commitment to the organization.

Pleural effusion is an abnormal collection of fluid in the pleural cavity. This study was designed to evaluate the clinical and etiological profile of patients with pleural effusion. A total of 138 cases (January 2016 to April 2019), the average age was 52 years, men predominated as women. The majority of the effusions are exudative and right-sided. About the etiologies are dominated by malignancy causes (32%) secondly the tuberculosis (31%) and cardiac etiologies (13%) with no apparent cause (9%). Despite the predominance of neoplastic etiologies in our series, tuberculosis remains the common etiology of pleural effusion whose evolution is favourable

The level of maternal mortality is an indicator of disparity in access to appropriate health care and nutrition services throughout their life particularly during pregnancy and childbirth. National Population Policy 2000 and National Health Policy 2002 aim to reduce the Maternal Mortality Rate (MM Rate) to 100 per 100,000 live births from the current level of 400-500. Though India has made an appreciable progress in improving the overall health status of its population but it is far from satisfaction. The pace of decline of maternal mortality on has been quite low. The death of a woman during pregnancy and childbirth is not only a health issue but also a matter of social injustice and discrimination. The complications of pregnancies and the births are found to be the foremost causes of maternal deaths. This measure reflects not only the risk of maternal death per pregnancy, but also the level of fertility in a population. The fertility beyond age 35 years is risky for both women and child and it leads to miscarriage, maternal & child mortality thus the study of the fertility beyond 35 years of age is an important issue for the researchers to study the status of maternal and child health. In this paper a simple technique has been proposed to estimate the MM Rate and MM Ratio using the age specific fertility rate (ASFR) and percentage of safe delivery beyond 35 years of age respectively, keeping in view of the above fact.

This research estimated the Well and Formation parameters of a Niger Delta Oil Well using pressure draw- down data. The well is located at longitude 050 53’ 19” and latitude 040 20’ 24”. The time to end strong wellbore storage effect (t*) was obtained to be 0.0025hrs and the time for the wellbore effect to end completely (50t*) was also determined as 0.125hrs. The wellbore storage constant (CS) value was obtained as 9.3x10-3 rb/psi, while the skin factor (S) was also obtained to be 23.4. The permeability to oil value (K) was obtained to be 954.4md and the Reservoir Pore Volume (Vp) value of 8.45 x 106 res bbl was also obtained.

The aim of the current study was to evaluate antimutagenic activity of ethanolic extract of Annona squamosa leaf which is belonging to the family Annonaceae. Its in vitro and in vivo antioxidant activity of the extracts has already been reported. On the basis of that we have decided to evaluate its antimutagenic activity in vivo in mice using bone marrow chromosomal aberration assay, micronucleus test and sperm abnormality assay. In chromosomal aberration assay, ethanolic extract of Annona squamosa (500mg/kg) had shown significant reduction in percentage of cells with aberration. In Micronucleus test, ethanolic extract of Annona squamosa (500mg/kg) showed significant reduction in total no. of micronucleus in polychromatic erythrocytes. In sperm abnormality assay, ethanolic extract of Annona squamosa (250 and 500mg/kg) had shown significant reduction in total no. of sperm shape abnormality. In conclusion, these results suggest that ethanolic extract of Annona squamosa leaves possessing significant antimutagenic property.

Malaysian SMEs are an important component of national economic development. According SMIDEC 2010, SMEs accounted for 93.8 percent in the manufacturing sector. Value added products from SMEs is expected to RM120 billion or 50 percent of total production in the manufacturing sector by 2020. The aim of this study to determine the performance of the employees of SME companies in the East Coast Economic Region (ECER). The study involved four determinants of system performance namely training and development, communication, work environment and reward. A total of 108 respondents were used to answer a questionnaire of selected companies that have been distributed to the respondents to obtain information related to the research carried out. The results of this study show that communication skills, reward, work environment and training & development are the success factors to improving their employee performance. In order to achieve national development goals of the management of SMEs companies need to take into account factors related to improving workers performance. This study show that all the determinants studied had a significant relationship at the significance level of p < 0.05.

Solid pseudo papillary neoplasm of the pancreas (SPNs) is a rare entity, known for its indolence. The pathogenesis of these tumors still controversial. Classic imaging characteristics include a large size, mixed density with solid and cystic components, encapsulation and hemorrhage. SPNs can show several criteria of malignancy such as local invasion, metastases and recurrence. Radical surgery is usually curative. We present a case of a Frantz Tumor in a 15-year-old female, with typical imaging features.

Theoretical studies were conducted on the molecular structure and vibrational spectra of 2-methoxy-6-methyl pyridine (MMP). The FT-IR and FT-Raman spectra of MMP were recorded in the solid phase. The molecular geometry and vibrational frequencies of MMP in the ground state have been calculated by using the ab initio HF (Hartree-Fock) /6-311+G(d,p) and density functional methods (B3LYP) invoking 6-311+G(d,p)/6-311++G(d,p) basis set. The optimized geometric bond lengths and bond angles obtained by HF method show best agreement with the experimental values. Comparison of the observed fundamental vibrational frequencies of MMP with calculated results by HF and density functional methods indicates that B3LYP is superior to the scaled Hartree-Fock approach for molecular vibrational problems. The difference between the observed and scaled wave number values of most of the fundamentals is very small. A detailed interpretation of the FT-IR and FT- Raman, NMR spectra of MMP was also reported. NBO analysis has been performed in order to elucidate charge transfers or conjugative interaction, the intra-molecule rehybridization and delocalization of electron density within the molecule. UV–vis spectrum of the compound was recorded and the electronic properties, such as HOMO and LUMO energies, were performed by time dependent density functional theory (TD-DFT) approach. Finally the calculations results were applied to simulated infrared and Raman spectra of the title compound which show good agreement with observed spectra.

The epidemiological approach to glomerular diseases remains less developed in our country. The aim of our study is to identify the frequency of glomerular nephropathies in our context; and to describe their different demographic, clinical, biological characteristics, as well as their etiological and evolutive profile. We have led a retrospective study at the department of nephrology, University Hospital Med VI, between 2014 and September 2017. We collected 93 patients, including 51 men .The average age at the diagnosis was of 34,8 ± 14,8 years old. The clinical presentation was dominated by the nephrotic syndrome (60.21%), hematuria (26/88%), and hypertention (22.58%).Glomerular nephritis were primitive in 70.96 % of the cases, the minimal change disease, segmental and focal glomerulosclerosis and membranoproliferative glomerulonephritis represented the most common histological types with 18,18%, 42,4% and 24,04% of the cases , their etiologies were dominated by lupus nephropathy, 78,3% of our patients received a symptomatic treatment . The use of corticosteroids in primitive glomerular nephropathy has been proposed in only 53.7 % of the cases, and associates with immune suppressives in 17.9% of cases.

Poly(2-oxazoline)s have widely been used in biomedical applications for the last years. They can mimick natural systems and they generally used as liposomes, drug and gene deliver and pseudopeptides. In this study investigating histological effects of different doses (10 mg/L, 50mg/L) of poly(2-ethyl-2oxazoline) (PEtOx) on liver tissue of zebrafish was aimed. Adult zebrafish individuals were exposed to different doses of PEtOxfor 5 days and after that they were dissected and liver tissues removed. Histological changes at liver tissue were investigated at light microscope after hematoksilen and eosin staining. In the experimental groups, contraction in vacuoles at hepatocyte cytoplasm, hypertrophy and increase in the number of hepatocyte cells and kuppfer cells were detected.
