Background: Breast cancer is the leading malignancy in women, but it is relatively rare in men, accounting for 1% of all breast cancers. In Morocco, its incidence is 0.8/ 100,000 in men. This condition epidemiology, therapeutic and prognostic remains unknown given the scarcity of reported series. The objective of this work is to identify the epidemiological, clinical, pathological and therapeutic of this cancer in men. Results: Six patients were diagnosed with breast cancer with a ratio of 6/1277 cases. The mean age of patients was 63.3 ± 9.7 ans; the most common histological type was invasive ductal carcinoma (83.3%). The grade 2 SBR has a majority (66.7%), while that of SBR 3 is less represented (33.3%). A positive estrogen receptor (66.7% of cases) and progesterone (50.0% of cases) was noted. The HER2 receptor is overexpressed in 25% of cases. The treatment was essentially surgical (83.3%). Additional treatment included adjuvant chemotherapy (50.0%), radiotherapy (50.0%) and hormonal therapy (16.7%) was administered. Discussion/Conclusion: Breast cancer in men is rare and appears to have a very close clinical, histological characteristics and prognosis to those of elderly women. The diagnosis is usually late and tumors are treated in advanced stages. An improved prognosis requires better awareness for early detection.

Introduction: Bad eating habits can have serious impact on oral health. Objec-tives: To study the impact of eating habits and dental hygiene practices on the dental status of students. Methods: Cross-sectional study of 400 students aged 17 and more, from the Ben M’Sik Sciences Faculty. A questionnaire on the so-cio-economic level of the parents, the eating habits, the means of hygiene and the oral health status has been filled in anonymously by the respondents. Uni-variate and multivariate descriptive and comparative analyzes were per-formed by the software SPSS 21. Results: The population’s average age is 20 ± 1.59 years old consisted of 55% of boys and 45% of girls. The breakfast is consumed by 67% of students. 39.58% respondents consume sweetened drinks during the meals and 60% at the end of meals and 66% are snacking during the day. 92% of students say they brush their teeth. The brushing time varies between 1 and 3 minutes. 37% of students do never consult a dentist and 63% in case of dental problems. The prevalence of caries is 66%. There is a positive association between the prevalence of tooth decay and certain eating habits (sweet things consumption (p = 0.08), cakes (p = 0.018) and chocolate (p = 0.019) outside of meals). However, this correlation is negative, when the consumption of these foods is done during meals (p > 0.74). On the other hand, there was no correlation between alcohol consumption and presence of caries (p = 0.172), tobacco consumption (p = 0.319), and socioeconomic status parents (p = 0.733). Conclusion: Oral hygiene and regular monitoring by a dentist with healthy eating habits can have a significant impact on the oral status of students.

Journal of Signal and Information Processing (JSIP) , 2013, DOI: 10.4236/jsip.2013.44050
Abstract: In this paper, we proposed an algorithm to estimate the reliability of a hybrid computer communication network. A hybrid computer network is a network that consists of wire and wireless sub networks. The proposed algorithm is built upon using a simulation model due to the complexity of the network topology. We tested the proposed algorithm, and the results show consistency in the reliability estimates.

Pan African Medical Journal , 2010,
Abstract: INTRODUCTION: Systemic lupus erythematosus (SLE) afflicts young people disproportionately, often at a crucial time in their lives when they are trying to establish relationships, start families and launch careers. As a result, persons with SLE may experience a wide range of physical and psychosocial problems that are not always fully captured by descriptions of the disease’s physiological consequences alone. METHODS: In order to characterize the spectrum of the effects of SLE with regards to disease activity and its impact on the quality of life (QoL), a case control study involving 59 SLE Egyptian patients (mean age 28.6 years , 94.9% females) and 20 healthy controls was undertaken. Disease activity was measured by SLE Disease Activity Index (SLEDAI), and quality of life was measured by Short Form 36 health questionnaire (SF-36). RESULTS: Mucocutaneous and hematological manifestations were present in most of the patients and arthralgia in half of them. All domains of SF-36 including general health, physical functions, physical limitations, energy/fatigue, emotional well-being, pain, social functions, and health changes were significantly lower in SLE patients compared to controls. Except for emotional limitations, all domains were correlated with disease activity and low in class IV-V lupus nephritis. CONCLUSION: Physicians should focus on QoL and how to improve it; health education regarding the negative impact of disease activity on the patients should be given attention. The results of QoL studies help physicians to understand and provide better support to SLE patients beside rapid meticulous control of disease activity

Abstract: Powder compacts of the system Bi2–xPbxSr2Ca2Cu3Oy with 0 ≤ x ≤ 0.5 molar ratio using both techniques; isothermal hot pressing and the solid state reaction (sintering). The XRD of the hot pressed powder compacts of the nominal compositions Bi2–xPbxSr2Ca2Cu3Oy showed 2212 and 2223 phases. The resistivity temperature variations belonging to the composition Bi1.8Pb0.2Sr2Ca2Cu3Oy showed metal-superconducting transition at Tons = 143 K for the annealed sample for 24 h. The annealed nominal composition Bi1.5Pb0.5Sr2Ca2Cu3Oy for 18 h showed metal to superconducting transition at 80 K.
Energy Balanced Self-Configuring Sensor Networks

Asian Journal of Information Technology , 2012,
Abstract: Like other distributed systems, unattended sensor networks need to be balanced, especially energy balanced. Lifetime of a sensor network can be maximized if a balanced network is formed. In this research, we characterize nodes based on their residual energy levels and distribute tasks according to a node s capability to balance energy over the network. We characterize a node as SEN, when that node is having sufficient energy to perform additional responsibilities other than its own sensing task. Otherwise, we characterize a node as NEN, when that node is having only a small amount of energy to perform its own tasks. Every node starts as SEN and at some point it becomes NEN based on a predefined threshold value. Thus, the nodes are protected from the early exhaustions. A virtual self-configuring clustering technique is also developed to rotate the tasks among nodes. We apply our approach to a simulation environment and the results justify our assertion.

Abstract: Background: Marital satisfaction is an important component of the marriage. Mental health as a component of the personal characteristic also related with marital satisfaction. The aim of this study was to investigate the association between mental health and marital satisfaction of couples.Methods: Three hundred couples from high-risk area of Gorgan – North of Iran were selected. Association between men's and women’s mental health level was measured using General Health Questionnaire-28 (GHQ-28). Marital satisfaction measured by Enrich Marital Satisfaction Questionnaire among married couples. Data was analyzed using multiple regression and analysis of variance modelling.Results: Results indicated that marital satisfaction was predicted by the person’s mental health level. Findings also showed that depression and anxiety were significantly associated with marital satisfaction. 52.5% of studied individuals had mental disorders at the clinical level (p≤0/05). Marital satisfaction in this population was 51.7%. Conclusions: The study confirmed that mental health is an important predictor of marital satisfaction. Improving mental health may lead to improve marital satisfaction.
Malaysian Journal of Pharmaceutical Sciences , 2006,
Abstract: The hyperglycemic effect of carbohydrate in the forms of 20 g each of glucose and sucrose and 26 g of honey were studied in eight normal volunteers and 22 type 2 diabetic patients. There was no significant (p>0.05) change in the glycemic response in normal group when challenged with glucose, sucrose or honey. However, in the diabetic group there was some attenuation in the glycemic response and was significant (p<0.05) after two hours of treatment with glucose, sucrose or honey used. The glycemic index (GI) showed considerable variability within subject groups. The results led us to speculate that honey could be a valuable sugar substitute for type 2 diabetic individuals and have a favorable GI for diabetes.
Design of Language Independent Speech Interfaces
Yasir Khalil Ibrahim,Mazin M. Al Hadidi
Information Technology Journal , 2006,
Abstract: Speech recognition technology has made spoken interaction with machines feasible. However, no universal interface has yet been proposed for human to communicate effectively, efficiently and effortlessly with machines via speech. Since the existing speech interfaces are language specific and language dependent, it is proposed to standardize the interface to make it language independent and adaptive to local dialects. The two existing primary models of speech recognition (Sehultz and Waibel, 2001) the acoustic model (analyses the sound of voice and convert them to phonemes) and the language models (compares the combination of phonemes to the words in its digital dictionary)-are language and speaker dependent. The extension of these models, Large Vocabulary Continuous Speech Recognition, is proposed in this study. Monolingual recognizers for multiple languages are designed first and the entire collection of phoneme set is called as GlobalPhone database. Based on this global unit set, it is aimed to make the resulting multilingual acoustic model as language independent. The phonemes with common sound are refined from GlobalPhone database to form a set of International Phonetic Alphabets (IPA). From this, the phonemes can be derived for any target language. To make the interface adaptive to different dialects, phoneme models of arbitrary context width called polyphones from resulting target language are maintained. By evaluating the Polyphone Decision Tree Specification, which is context-relative of that target language, the recognizer can be adapted to all accents and dialects of that particular language.

Abstract: Petrographic, mineralogical and geochemical investigations were carried out on representativesamples from the Mudawwara-Quwayra Dike (MQD) in southernJordan. The MQD intruded Paleozoic and Cretaceous rocks as sub-vertical basaltic plugs, striking NW-SE along a fault zone and extending for more than 100 km. The MQD forms irregularly positive features, and is represented by symmetrical, elliptical, elongated or circular hills. It comprises thin basaltic layers intercalatedwith pyroclastics and inclusions of different size and lithology, including limestone, sandstone, phosphate, quartzite, and marble. Petrographically, the rock exhibits phyric, porphyritic, vitrophyric and locally glomerophyritic textures manifested by plagioclase, clinopyroxene and rareolivine and set in a matrix of plagioclase, pyroxene, brown glass and opaque phases. Clinopyroxeneand olivine phenocyrsts show disequilibrium textures such as reaction/resorbed rims in theforms of corroded ends. The paragenetic sequence shows that olivine is the first phase to be crystallized and coexisting with pyroxene at sometime, while pyroxene continues crystallization. Plagioclase might have crystallized in contemporaneous later than the pyroxene. The MQD rocks are classifiedas basalt and exhibit a narrow range of silica with a unique subalkaline affinity. This is mostprobably attributed to assimilation of the abundant siliciclastic inclusions by the ascending magma. Emplacement of the MQD is attributed to regional phase of
