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.

Mancozeb is a synthetic pesticide which has been used for decades. It is used to hinder the growth of fungi and plants against damage. Pesticides access aquatic ecosystems via ground waters and affect water quality and aquatic life. In our study, investigation the histopathological effects of mancozeb on intestine tissue of zebrafish were aimed. Degeneration and expansion at villi structure and increase in the number of goblet cells, mucus accumulation and expansion in muscular layer were detected at exposure groups. Depending on the increased number of leukocytes enteritis was monitored.

To speed up the process of detection of tamper in an image it is withheld to segment the image, embed segment with watermark and key as to trace the tamper segment in which key is not found rather than tracing for entire image for tamper detection. Tamper detection algorithm based on superpixel segment level key encryption with svd based watermarking scheme is proposed. This method finds tamper location from watermarked superpixel segments of watermarked image. Secrete key embedded in each segment of watermarked image for finding tamper segment first. If keys not found from any of the segment that segment shows tamper segment of image then find area which is tampered from that segment. To improve the efficiency of the proposed tamper detection against various security attacks such as collage attacks, VQ attacks and content removal attacks. The experimental results shown that proposed tamper detection scheme is shows better performance in terms of efficiency of tamper detection rate higher than 99% in average complex attacks, 100% in common attack and tamper finding speed is 0.02 to 0.04 sec. in various attacks.

Education has the key role in human capital formation. It empowers the society by increasing awareness, skills, efficiency and productivity, but does it empowers the people who educate the society? This paper scrutinizes the impact of different education levels on teacher’s earnings of public sector educational institutes in Pakistan. By employing Mincerian Human Capital model. A sample of 150 teachers is used for the analysis. Data is collected through field survey and questioner about educational level and experience from public sector teaching staff of Quetta city and OLS Regression method is used to determine the impact of Education and experience on earning. According to our results, completed years of education and years of experience have positive significant impact on monthly income. But years of experience increases income at a decreasing rate.

This paper focuses on the structure of corporate leadership and how it can help achieve Early Childhood Education (ECE) goals in protecting the rights of children. It establishes that corporate leadership has not fully been exercised and implemented in Early Childhood Development (ECD) centres, and this is due to the administrator’s inability to steer stable and sustainable centres for protection of rights of children and unprofessional management. The study employed descriptive surveys, and stratified sampling was used to obtain a sample of 52ECD centres in Baringo County, Kenya and the target population involved the staff in ECD centres. This paper establishes that corporate leadership is vital towards accomplishment of protecting rights of children and that curriculum supervision plays a major role in quality education and protecting children rights. Therefore it recommends a full review of implementation of corporate leadership in ECD centres and training of staff to achieve this course

Rice bran, one of the most abundant and valuable byproducts produced during the rice milling process, is of steadily growing interest in recent years due to its potential health benefits. Herein, we investigate and report the physicochemical properties of rice bran obtained from Mubi, Adamawa State, Nigeria. The rice bran was initially combusted and soil samples of the baked, unbaked soil and surrounding particular area where we carried out the combustion were collected and analyzed for its physicochemical properties. The results revealed that the baked soil has a higher concentration of calcium, magnesium, potassium and sodium than the unbaked soil. Furthermore, retention of water (tension) and the ability to absorb water (infiltration) was discovered to be higher in the baked soil sample. This shows that the heat of combustion of rice bran affects the physical, chemical and mechanical properties of soil in a peculiar way.
