Abstract: Hypertension is a challenge for public health professionals all-over the world. It is the leading and most important modifiable risk factor for coronary heart disease, congestive heart failure, stroke, renal diseases, retinopathy and many other diseases. The aim of the present study is to evaluate and study the most identifiable risk factors for patients with diseases of hypertension and diabetes mellitus such as age, gender, marital status, tobacco smoking, life style and with associated diseases (dyslipidemia and diabetes) treated at city hospital in Tripoli (Tripoli Medical Centre). This was a cross sectional prospective study which was carried out during October 2013 and January 2014. The study included 200 consecutive patients (102 females and 98 males) who are older than 30 years and who came for a regular follow up at the OPD of Tripoli medical centre. During this study, variables like age, gender, diabetes, smoking and dyslipidemia were taken into account in relation to hypertension. In addition, it is assorted some important biochemical parameters such as total cholesterol, triglycerides, low density lipoprotein, high density lipoprotein and fasting blood glucose in the studied population and compared them with available data. The findings revealed that Libyan population not only old age and male gender are potential threat for an early hypertensive but other variables like diabetes, cardiovascular diseases, dyslipidemia, obesity, migraine and obstructive apnea are also playing an important role in hypertension complications. It is concluded that this population is more prone to hyperglycemia and high pulse pressure with hypertension in the majority of survey population

Abstract Mel Frequency Cepstral Coefficients (MFCCs) are the most widely used features in the majority of the speaker and speech recognition applications. Since 1980s, remarkable efforts have been undertaken for the development of these features. Issues such as use suitable spectral estimation methods, design of effective filter banks, and the number of chosen features all play an important role in the performance and robustness of the speech recognition systems. This paper provides an overview of MFCC's enhancement techniques that are applied in speech recognition systems. The details such as accuracy, types of environments, the nature of data, and the number of features are investigated and summarized in the table combined with the corresponding key references. Benefits and drawbacks of these MFCC's enhancement techniques have been discussed. This study will hopefully contribute to raising …

Abstract: Objective: The present study has been designed to evaluate the histological effects of the daily consumption of omega-3 on submandibular salivary gland of old rats. Material & methods: Forty old white male rats (12-15 month age old), weighing 300 to 350gs, were used in this study. The rats were divided into two groups (20 rats/each). Control group where rats did not receive any dietary supplement. Experimental group where rats received omega-3 (60 mg/Kg) twice daily for three months through intra- gastric intubation. All rats were sacrificed after three months. Soft tissue specimens were obtained from submandibular salivary gland of the rats in all the studied groups. The sections were examined histologically and ultra-structurally. Results: Histopathological changes observed in control group included; distortion and decrease in the overall size of the acini and granular convoluted tubules increase in the amount of fatty tissue, fibrous tissue and inflammatory cell infiltration. In experimental group, the acini and ducts appeared nearly normal and there was marked decrease in the inflammatory cell infiltration. Electron microscopic examination of the control group revealed cytoplasmic vacuolization in acini and ducts, degenerated organelles and pyknotic nuclei. In experimental group, the acini and ducts appeared nearly normal in size, shape and structure. Conclusion: Omega-3 showed significant improvement in many age related changes of submandibular salivary gland.الملخص: الهدف: صممت الدراسة الحالية لتقييم التأثيرات النسيجية لليوم استهلاك أوميغا 3 على الغدد اللعابية تحت الفك السفلي للفئران القديمة. المواد والطرق: أربعون ذكرا أبيض يبلغ من العمر تم استخدام الفئران (12-15 شهرا) ، التي تزن 300 إلى 350 جراما ، في هذه الدراسة. تم تقسيم الفئران إلى مجموعتين (20 جرأ / لكل منهما). المجموعة الضابطة حيث لم تتلق الفئران أي مكمل غذائي. المجموعة التجريبية حيث الفئران تلقى أوميغا 3 (60 مجم / كجم) مرتين يوميا لمدة ثلاثة أشهر من خلال التنبيب داخل المعدة. تم التضحية بجميع الفئران بعد ثلاثة أشهر. تم الحصول على عينات الأنسجة الرخوة من الغدة اللعابية تحت الفك السفلي للفئران في جميع المجموعات المدروسة. تم فحص الأقسام من الناحية النسيجية والهيكلية الفائقة. النتائج: نسيجية مرضية وشملت التغييرات التي لوحظت في المجموعة الضابطة; تشويه وانخفاض في الحجم الكلي للأسيني والحبيبات تزداد الأنابيب الملتوية في كمية الأنسجة الدهنية والأنسجة الليفية وتسلل الخلايا الالتهابية. في المجموعة التجريبية ، بدت الأسيني والقنوات طبيعية تقريبا وكان هناك انخفاض ملحوظ في الالتهابات تسلل الخلايا. كشف الفحص المجهري الإلكتروني للمجموعة الضابطة عن تفريغ السيتوبلازمي في أسيني والقنوات والعضيات المتدهورة والنوى pyknotic. في المجموعة التجريبية ، ظهرت الأسيني والقنوات تقريبا طبيعي في الحجم والشكل والهيكل. الخلاصة: أظهرت أوميغا 3 تحسنا كبيرا في العديد من الأمراض المرتبطة بالعمر تغيرات الغدة اللعابية تحت الفك السفلي.

Abstract— Diagnosing skin cancer in its early stages is a challenging task for dermatologists given the fact that the chance for a patient’s survival is higher and hence the process of analyzing skin images and making decisions should be time efficient. Therefore, diagnosing the disease using automated and computerized systems has nowadays become essential. This paper proposes an efficient system for skin cancer detection on dermoscopic images. It has been shown that the statistical characteristics of the pigment network, extracted from the dermoscopic image, could be used as efficient discriminating features for cancer detection. The proposed system has been assessed on a dataset of 200 dermoscopic images of the ‘Hospital Pedro Hispano’ [1] and the results of cross-validation have shown high detection accuracy.

In certain extremely low probability, severe accident scenarios which have been postulated for liquid metal cooled fast reactors, large bubble cavities containing fuel vapor and fission products transit a layer of coolant and release this material to the cover gas thereby presenting a contribution to an accident-specific source term. So that a more mechanistic assessment of these types of events can be developed, analyses have recently been performed to account for the heat and work transfer observed in out-of-reactor source term experiments conducted during the 1980’s for oxide fueled reactors in the Fuel Aerosol Simulant Test (FAST) facility at Oak Ridge National Laboratory. In ten experiments, UO2 specimens were vaporized in pools of sodium, and for an additional number of benchmarking tests, in pools of water, for purposes of experimentally assessing the bubble transport characteristics of both types of pools. The current analyses present several firsts for these experiments: (a) a comparison of the bubble-to-coolant transfer rates; heat versus work, (b) a bubble-to-coolant heat transfer model accounting for how condensation and radiation heat transfer are affected by coolant selection; sodium versus water, and (c) an assessment of how both types of heat transfer influence the movement of aerosol-laden bubbles through the coolant pool. These analyses significantly extend previous evaluations of FAST experimental results by providing a more comprehensive model for determining how bubble-coolant interactions affect aerosol transport and, in this way, contribute to data base development associated with mechanistic assessments of the source term.

The theory of analytic functions and more specific p-valent functions, is one of the most fascinating topics in one complex variable. There are many remarkable theorems dealing with extremal problems for a class of p-valent functions on the unit disk U. Recently, many researchers have shown great interests in the study of differential operator. The objective of this paper is to define a new generalized derivative operator of p-valent analytic functions of fractional power in the open unit disk U. This operator generalized some well-known operators studied earlier, we mention some of them in the present paper. Motivation by the generalized derivative operator; we introduce and investigate two new subclasses of starlike p-valent analytic functions of fractional power with positive coefficients and starlike p-valent analytic functions of fractional power with negative coefficients, respectively. In addition, a sufficient condition will be obtained. Some corollaries are also pointed out. Moreover, we determine the extreme points of functions belong to the class.
