Anthropometric measurements of the external nose in 18–25-year-old Sistani and Baluch aborigine women in the southeast of Iran

The human nose differs in its anatomy and morphology between different racial and ethnic groups. The objective of this survey was to provide data for clinical plastics of the nose, medical aesthetics and cosmetology, anthropology, nationality study, and medical jurisprudence in Sistani (Fars) and Baluch aborigines in the southeast of Iran. The subjects participating in this study were 400 volunteer Baluch and Sistani aborigine women (in both groups the number of subjects was 200) within the age range of 18&#8211;25 years. Anthropometric data were obtained from all subjects using standard anthropometric methods with a sliding calliper. The data were analyzed using SPSS 11.0. Values were expressed as mean &#177; standard deviation (SD). Student t-test was used to compare the results. A p value of less than 0.05 was considered significant. The mean total length and height of the nose in the Sistani group was significantly (p < 0.001) lower than in the Baluch group (46.5 &#177; 1.8 vs. 53.0 &#177; 1.3; 44.0 &#177; 2.2 vs. 49.5 &#177; 2.0). The mean anatomic width of the nose in the Sistani group was higher than in the Baluch group (32.3 &#177; 1.3 vs. 31.4 &#177; 1.5 mm). The nasal index in the Sistani group was significantly (p < 0.001) higher than in the Baluch group (69.7 &#177; 3.5 vs. 59.2 &#177; 3.3). The most common type of nose was leptorrhine (fine nose), accounting for 55.5% in the Sistani group and 98.5% in the Baluch group. The most common type of face in both groups was leptoprosopic. In spite of significant differences in measurements of noses in the Sistani and Baluch groups, the most common types of nose and face were similar in these two groups

The Relationship between Knowledge Management and Organizational Learning with the Effectiveness of Ordinary and Smart Secondary School Principals

This study aimed to investigate the relationship between knowledge management and organizational learning with the effectiveness of ordinary and smart high school principals in Zahedan Pre-province. The statistical community of this research is 1350 male and female teachers teaching in ordinary and smart students of high schools in that 300 ones were selected by stratified random sampling based on Morgan Table and the rate of the principals’ knowledge management was measured using Phong’s Modified Questionnaire (2009). Neefe’s Modified Questionnaire is also used for organizational learning and the effectiveness of principals has been measured using Pokharel’s Revised Questionnaire (2005). The reliability coefficients of the questionnaires were achieved 0.92 in knowledge management, 0.93 in organizational learning and 0.88 in its effectiveness using Cronbach’s alpha. In addition, their validity was confirmed by the instructors. The obtained data were analyzed using statistical indicators such as mean, Pearson correlation coefficient, independent t-test as well as regression in SPSS software and the final model was confirmed using structural equations in LISREL software. The results obtained in this study showed that there is a significant relationship between knowledge management and organizational learning in ordinary and smart schools. In other words, organizational learning increases by the increase of knowledge management in that this increase in smart schools is more that of ordinary ones. The general relationship between knowledge management and organizational learning with the effectiveness of ordinary and smart schools principals was approved. The outcomes obtained regarding gender variable indicate a higher average of male principals in comparison to female principals

A Digital Image Watermarking Method in the Discrete Cosine Transformation Domain

In this paper, a watermarking method has been proposed based on Discrete Cosine Transform(DCT) which can be used in order to protect copyrighting and to provide right of image ownership. In this method, the original image transferred to DCT domain after dividing into non-overlapped blocks 8×8 and to the same method, watermark image which can be whether a firm mark or any desired image from owner of the art work, after dividing into non-overlapped blocks 4×4, transferred to DCT domain. Watermark image coefficients after one step coding composed with low frequency coefficients of original image and create the final watermark image. On the other hand, the process of reforming watermarked image and extracting the original watermark on the secondary side is extractable by using original image and with reverse mechanism. Experiments show that this method in encountering with a number of routine attacks has a good resistance

C-Peptide Effects on Renal Physiology and Diabetes

The C-peptide of proinsulin is important for the biosynthesis of insulin and has for a long time been considered to be biologically inert. Animal studies have shown that some of the renal effects of the C-peptide may in part be explained by its ability to stimulate the Na,K-ATPase activity. Precisely, the C-peptide reduces diabetes-induced glomerular hyperfiltration both in animals and humans, therefore, resulting in regression of fibrosis. The tubular function is also concerned as diabetic animals supplemented with C-peptide exhibit better renal function resulting in reduced urinary sodium waste and protein excretion together with the reduction of the diabetes-induced glomerular hyperfiltration. The tubular effectors of C-peptide were considered to be tubule transporters, but recent studies have shown that biochemical pathways involving cellular kinases and inflammatory pathways may also be important. The matter theory concerning the C-peptide effects is a metabolic one involving the effects of the C-peptide on lipidic metabolic status.This review concentrates on the most convincing data which indicate that the C-peptide is a biologically active hormone for renal physiology

Histological and immunohistological aspects of the ovarian cycle of the algerian wild sand rat, Psammomys obesus Cretzschmar, 1828.

The sand rat, Psammomys obesus, is largely used as a model for studying several metabolic disorders. In order to perform breeding laboratory conditions, the reproductive function of this species was investigated. Using histological and immunohistochemical techniques, several aspects of the ovaries were studied throughout the sexual cycle. During the ovarian cycle, the different stages of folliculogenesis, from primordial to Graafian follicle, have been shown; the differentiation of both granulosa and theca cells, the formation of the antrum, cumulus oophorus and corona radiate were described. Broken follicles and corpora lutea have been observed, confirming a spontaneous ovulation in isolated females. Steroid activities were analysed using immunohistochemical techniques. Estrogen, androgen and progesterone hormones were visualized in the different compartments of the ovary

Morphometry and immunohistochemistry of follicles growth and steroidogenesis in saharian wild sand rat, Psammomys obesus, ovary.

The sand rat (Psammomys obesus) constitutes a model to study seasonal changes and several metabolic disorders. In order to perform breeding laboratory conditions, the reproductive function of this species living in North Occidental Algerian Sahara was studied. The aim of this work was to investigate the follicular growth changes and the steroidogenic associated aspects. The study was performed using morphometrical and immunohistochemical methods. From primordial to preantral states, the follicle diameter increased progressively from 17-20 mum to 192-225 mum. The preovulatory follicles reached about 500 mum in diameter. Immunoreactivity to progesterone, androstenediol and estradiol, varied in the different parts of the ovary and follicular cells. The progesterone antibody appeared clearly labelled in the theca interna of the growing follicle and increased in the granulosa; the androgen antibody was continuously weak and diffuses in all follicles; the estradiol labelling appeared weak and diffuse in preantral follicles then increased in antral follicles in both theca and granulosa or only in granulosa. In antral follicles, estradiol label was clearly localized in granulosa cells and totally devoid in theca cells. In Psammomys ovary, labels of hormone were diffuse or localized, weak or intense in the theca and or in the granulosa according to the follicle size

An Investigation of Geographical Spread of Iranian Cities Based on Altitude

The spread of Iranian cities is manifested in different geographical directions including regional, bio-environmental features and many other factors. The purpose of the present study is to investigate and analyze the spread of Iranian cities based on the altitude from the sea level. The method of this research is analytical-descriptive. To analyze the data, the researchers have used the Zapf's most famous formula. Based on this formula, all the Iranian cities were divided into 11 categories in which the lowest category was 26 and the highest was 2790 from the sea level. Generally, the obtained results showed that that the spread of Iranian cities due to good weather condition and altitude from sea level was the most with the number of 227 or 19.30% and the least number of cities was at the altitude of 2536 with only 8 cities
