Houriya Mestaghanmi, Ali Labriji, Imane M’Touguy, Fatima Zahra Kehailou, Said Idhammou, Nabil Kobb, Fatema Zahra Mahfoud, Ahmadaye Ibrahim Khalil, Souad El Amrani
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104967
Abstract:
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.

Imane M'Touguy, Nadia Iounes, Fatema Zehra Mahfoud, Marwa Chhail, Amine El Khatib, Rachid Saile, Souad El Amrani, Houriya Mestaghanmi
Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1103259
Abstract:
Background: An energy drinks supposed to give a boost of energy to the consumer. It usually contains caffeine and lot of sugar. We studied the risks associated with the consumption of these drinks, the conditions in which they are consumed and the frequency of obesity in the determination of body mass index among 195 students of the Faculty of Sciences Ben M’Sik. Methods: This is a survey conducted by students of the Ben M’sik Faculty of Sciences, Hassan II Casablanca University, during the year 2015, using a questionnaire exploring the consumption of energy drinks. Results: Our study shows 195 of surveyed students consuming energy drinks, of which 22.0% are girls and 78.0% are boys, of which 16.5% were overweight, 5.5% moderate and 2% severe obesity. 9.2% of students consume them to quench the thirst, 10.8% to bring their body energy, 7.7% for their taste, 21.5% to mitigate fatigue, 6.2% to stimulate and 44.6% for all the reasons cited. 4.6% say they associate them with tobacco, 4.0% with alcohol and 6.8% with some drugs during review periods. The consequences of poisoning these drinks can be serious health and manifest as tachycardia (3.2%), agitation or confusion (29.3%), abdominal pain (7.9%), hypertension (19.4%). These symptoms experienced are significantly higher among consumers of these drinks compared to controls. Witnesses consume either energy drinks or sugary drinks. Discussion/Conclusion: That frequent consumption of energy drinks may pose a risk and a danger to the health of consumers, hence the need for awareness especially young people against their effects. Public health organizations must also keep a close watch on this new trend.
Unidade da pessoa segundo Edith Stein: contribui??es à educa??o para a nutri??o
Mahfoud, Miguel;
Psicologia USP , 2008, DOI: 10.1590/S0103-65642008000400003
Abstract: study regarding the relationship between education and nutrition with a focus on unity of the person, education as formation and development of the person. with edith stein's concept of "personal center" and "vital force", the main points of the subject's interests regarding personal life and its surrounding world are examined. the unity of the person - physical, psychological and spiritual -, its non-alienating relation with the social context and the proper constitution of community depend on those points. the study concludes that without a possible path that points toward the formation of the person, so that each one becomes more oneself, the process of personal or social care can not be established.
Sport, Islam, and Muslims in Europe: in between or on the Margin?
Mahfoud Amara
Religions , 2013, DOI: 10.3390/rel4040644
Abstract: The aim of this paper is to reveal how misconceptions—or using the concept of Arkoun, “the crisis of meanings”—about the role and position of Islam in Europe is impacting on the discourse on sport, Islam, and immigration. France is selected as a case study for this paper as it is in this country where the debate on religion in general and Islam in particular seem to be more contentious in relation to the questions of integration of Muslim communities to secular (French republican) values. Recent sources of tensions include the ban of the Burqa in the public space; the debate on national identity instigated by the former French president Nicholas Sarkozy, which became centred around the question of Islam and Muslims in France; the provocative cartoons about Prophet Mohamed in the satirical magazine Charlie Hebdo; opposition against the provision of halal meal in France’s fast-food chain Quick; and resistance toward Qatar’s plan to invest in deprived suburbs of France, to name just a few. The other context which this paper examines in relation to the question of sport, Islam, and identity-making of Muslims in Europe is the phenomenon of “reverse migration” or the re-connection of athletes of Muslim background in Europe, or so-called Muslim neo-Europeans, with their (parents’) country of origin. The paper argues that sport is another highly politicised space to judge the level of “integration” of Muslim athletes in European societies, and the degree of “religiosity” in their (parents’) country of origin.
A Novel Approach for Image Steganography in Spatial Domain
Fatema Akhter
Computer Science , 2015,
Abstract: This paper presents a new approach for hiding information in digital image in spatial domain. In this approach three bits of message is embedded in a pixel using Lucas number system but only one bit plane is allowed for alternation. The experimental results show that the proposed method has the larger capacity of embedding data, high peak signal to noise ratio compared to existing methods and is hardly detectable for steganolysis algorithm.

Open Journal of Veterinary Medicine (OJVM) , 2014, DOI: 10.4236/ojvm.2014.47017
Abstract:

West Nile virus (WNV) is a mosquito-borne flavivirus contributing yearly, to birds, horses and human morbidity and mortality throughout the world. WNV is transmitted mainly by mosquitoes, predominantly by Culex species, to avian hosts and other vertebrates. Since the mid-1990s, WNV outbreaks and severe human cases (i.e., West Nile neuroinvasive disease) have increased throughout the North hemisphere. The absence of human vaccine and effective therapy needs to understand the pathogenesis of WN severe disease as well as factors participating in WNV transmission and mosquito exposure. The exploration of the host/vector interaction at the individual level using host antibody response against mosquito salivary proteins has open news research opportunities aiming to increase the impact of surveillance and WNV vector control strategies. This review describes Culex saliva specific biomarkers as a helpful tool to estimate exposure to vector bites and risk for WNV infection, summarizes recent advances regarding WNV vector control strategies and highlights potential specific biomarkers of WN disease severity.

Misleading Communication VS. Effective Aviation Management  [PDF]
Keshavarzi Zahra
Intelligent Information Management (IIM) , 2011, DOI: 10.4236/iim.2011.36029
Abstract: In this paper some of the important problems and issues such as human and communication errors in safety and civil aviation management are presented. The problems arise from misleading information from different sources. To avoid the above problems, a centralization of the information is proposed here. To centralize the information for Air Traffic Management (ATM), a mining data routing system called SCADA (Supervisory Control and Data Acquisition) system is suggested in this study. The utilization of SCADA system will helps to capture air traffic information and aircraft data via satellite technology and transfer it to data mining center and then to central organization. The stored digital data will exchange the information between different organizations and will be used by management systems. The stored reliable information helps to make an appropriate decision in the Air Traffic Management system.
Epidemiology of hodgkin’s lymphoma  [PDF]

Health (Health) , 2013, DOI: 10.4236/health.2013.55A003
Abstract:

The epidemiology of Hodgkin’s Lymphoma (HL) varies with age at clinical onset. In developing countries, the disorder appears predominantly during childhood and its incidence decreases with age, while in industrialized countries, the incidence rate increase with age. There has long been a view that the differences in descriptive epidemiology of Hodgkin’s Lymphoma around the world, and also between children, young adults and older adults may reflect differences in etiology between them. Hodgkin’s Lymphoma has long been suspected to have an infectious precursor, and indirect evidence has implicated Epstein-Barr virus (EBV), as a causal agent. The etiology of EBV-negative cases remains obscure. Epidemiological investigation of the etiology of Hodgkin’s Lymphoma is making steady progress, and it leads to a better understanding and hence prevention. This review considers in detail the descriptive and the etiological epidemiology of Hodgkin’s Lymphoma.

Abstract: The study area is located in the Zagros Simply Folded Belt of Iran and in the interior Fars sub-basin (175 km from Persian Gulf). The Zagros fold-thrust belt is home to one of the largest petroleum producing reservoirs in the world. Structures in this area have complications and the study anticline has unique structures in the Fars region. In the study area, the Kuh-e Qazi anticline due to special fold style and rotation toward Northeast is the unique structure between anticlines of the Zagros belt. This anticline is fault bend fold and plunge of the anticline in eastern part rotated toward Northeast along with the Nezamabad fault trend. In this area, the Kuh-e Qazi anticline has asymmetric structures and some faults such as the Nezamabad and the Sarvestan strike slip fault effect on this anticline. The geometry of anticlines in the Zagros fold-thrust belt is affected by the type of deformation and mechanical behavior of stratigraphic units specially detachment units. The purpose of this research is to determine of folding pattern of the Kuh-e Qazi anticline and define structural features affected on them in the study area. This paper presents a part of the results of a regional study of the Fars province in the Zagros Simply Folded Belt, based on original fieldwork, satellite images, structural sections, geological maps and well data. Also, we use some software as Global Mapper and Tectonics FP for preparing some data.?Based on the research, which have been done, the boundary between ductile and frictional substrates causes rotation as a result of lateral, along-strike migration of the ductile substrate. The ductile or viscose layer in the study area is Hormuz Series. Due to lack or thinning of Hormuz salt over the Gavbandi basement high and in the eastern side of the Nezamabad basement fault, causes translation of strain and anticlockwise rotation in Southeast of the Kuh-e Qazi anticline toward Northwest unlike foreland basin due to the Nezamabad fault activity. This style between all of the anticlines in the study area is unique that rotates unlike foreland basin. In addition, influence on anticlockwise rotation, extensional stress has been created and then salt dome cropping out in Southeast of the Kuh-Qazi anticline. One of the best evidence for effect of extensional stress is triangular facets in this part of the study anticline. Based on folding analysis (geometry of axial plane and fold orientation), it is clearly confirmed that the translation of strain and anticlockwise rotation in Southeast of the Kuh-e Qazi anticline toward Northwest
Large Squirrel Cage Induction Motor Reliability Modelling
Mahfoud Chafai,Larbi Refoufi
Journal of Engineering and Applied Sciences , 2012,
Abstract: In this study a simplified reliability model is developed on the basis of knowledge, from field data, of the dominating failure modes and mechanisms of large power squirrel cage induction motors operating at constant speed and fed from a conventional 3 phase sinusoidal supply voltage. Field data failures distribution indicates a dominance of failure modes pertaining to machine bearings and stator winding insulation. The motor system can be regarded as a complex combination of three fundamental parts: The stator, the rotor and the bearings which are respectively electrical, electromechanical and mechanical in nature. On this basis, the motor system reliability block diagram is modelled in a series configuration comprising the above mentioned parts. The individual reliability functions developed for each part will yield together the overall motor system reliability.
