Abstract: routines and rituals are a means to organize daily life. family identity, those beliefs, values, norms, rules and expectations shared among members, are also sustained by family rituals. the creation and maintenance of routine and ritual is a central element of family life and constitutes a scaffolding that supports the development of the child. daily life it may be considered a protective factor that promotes family wellbeing, increasing the sense of security, belonging, stability, cohesion and satisfaction, and strengthening social skills in children. this study aimed to analyze the relationship between family routines and rituals, and childrens' social skills. 107 families participated in this study and were administered the "family ritual questionnaire, family routines inventory, self-perception of the parental role". the study also involves teachers in the assessment of child competence through the "strengths and difficulties questionnaire". results show that not only the absence, but also the excess of routines and the emphasis on routines could lead to dysfunction in childrens' emotion regulation.

Abstract: Occult HBV infection is defined as the presence of hepatitis B virus (HBV) DNA in blood or liver tissues in patients negative for Hepatitis B surface Antigen (HBsAg). Those patients may or may not be positive for HBV antibodies. The objective of this study is to determine the presence or absence of HBV DNA in the serum samples from HBsAg negative blood donors. In addition we aimed to assess the magnitude of occult HBV infection and to reduce the risk of HBV infection. Over a period of one year a total of 7340 blood units were collected at blood transfusion center in our locality for the prevalence of HBV infection and 180 HBsAg negative blood specimens were randomly selected for anti-HBcIgM, anti-HBs antibody and HBV DNA. Ninety seven out of 7340 collected blood units were positive for HbsAg (1.3%).The randomly selected 180 tested donors revealed 7 (3.8%) positive for antiHBc IgM and 34 (18.8%) were positive for anti-HBs antibodies. Four out of 7 positive for anti-HBc IgM were also positive for anti-HBs and 2/180 (1.1%) specimens were positive for HBV DNA by PCR. Anti-HBc antibody should be tested routinely at any blood transfusion center and if they were positive regardless of anti-HBs titer, the blood should be discarded. Also HBV DNA is preferable to be performed to all blood donors to present completely safe blood transfusion.
Lecture Notes of Möbuis Transformation in Hyperbolic Plane  [PDF]
Rania B. M. Amer
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.515215

In this paper, I have provided a brief introduction on M?bius transformation and explored some basic properties of this kind of transformation. For instance, M?bius transformation is classified according to the invariant points. Moreover, we can see that M?bius transformation is hyperbolic isometries that form a group action PSL (2, R) on the upper half plane model.

La militance religieuse des étudiantes musulmanes descendantes de parents originaires du Maghreb* Religious activism among female Muslim students descendants of Maghreb migrant families

Revue des Mondes Musulmans et de la Méditerranée , 2012, DOI: 10.4000/remmm.6826
Abstract: L’irruption récente du voile dans l’espace public masque la temporalité, moins visible, du processus de conversion interne à l’islam des étudiantes descendantes de parents originaires du Maghreb. Ce processus, à la fois cohérent dans son unité et scandé par de grandes ruptures, se déroule en quatre étapes traversées par une même dialectique de l’arrachement et du rattachement : 1/ le temps du questionnement identitaire, temps de la déstabilisation de l’identité individuelle et du rejet des marqueurs ethniques ; 2/ le temps de l’adolescence , temps des choix et de la rappropriation de l’origine ; 3/ le temps exploratoire des possibles religieux, temps de l’affranchissement de la transmission patriarcale et de la libre enquête autodidactique ; 4/ le temps de la militance , temps de l’invention d’une islamité féminine originale des s urs . In fine, la description de la trajectoire idéaltypique du processus conversionnel des étudiantes fran aises descendantes de migrants maghrébins pose la question de la possibilité d’une émancipation féminine structurée par l’engagement religieux. Elle ouvre à celle, paradoxale et polémique, de l’émergence d’un féminisme islamique. The recent emergence of the veil in public places overshadows the slow development of the process of internal conversion to Islam among young female students descendants of Maghreb migrant families."Entry" into religion cannot be regarded as a sudden occurrence. It is an intense dialectical process of painful separations followed by renewed ties which gives meaning to, even shapes identity reconstruction. The typical ideal path of French female students' conversion to Islam goes through four analytic phases and ultimately raises the issue of a possible emancipation of women structured by religious commitment. The different phases examined in our study are as follows: the first phase is one of questioning identity, destabilization of individual identity and rejection of ethnic markers. The second is the phase of adolescence. The third is the exploratory phase of religious possibilities. Finally, the fourth and last phase is a time for religious activism (University/mosque). Thus, the quest for emancipated behavior, part of a process of modernity, occurs through their religious activism. A problematic and controversial quest for Islamic feminism then emerges from this paradox.

A Local-global Summation Formula for Abelian Varieties
Rania Wazir
Mathematics , 2003,
Abstract: Let $K$ be a field finitely generated over ${\Q}$, and $A$ an Abelian variety defined over $K$. Then by the Mordell-Weil Theorem, the set of rational points $A(K)$ is a finitely-generated Abelian group. In this paper, assuming Tate's Conjecture on algebraic cycles, we prove a limit formula for the Mordell-Weil rank of an arbitrary family of Abelian varieties $A$ over a number field $k$; this is the Abelian fibration analogue of the Nagao formula for elliptic surfaces $E$, originally conjectured by Nagao, and proven by Rosen and Silverman to be equivalent to Tate's Conjecture for $E$. We also give a short exact sequence relating the Picard Varieties of the family $A$, the parameter space, and the generic fiber, and use this to obtain an isomorphism (modulo torsion) relating the Neron-Severi group of $A$ to the Mordell-Weil group of $A$.

Abstract: In this note, we apply Moriwaki's arithmetic height functions to obtain an analogue of Silverman's Specialization Theorem for families of Abelian varieties over $K$, where $K$ is any field finitely generated over ${\Q}$.
Arithmetic on Elliptic Threefolds
Rania Wazir
Mathematics , 2001,
Abstract: In a recent paper, Rosen and Silverman showed that Tate's conjecture on the order of vanishing of L(E,s) implies Nagao's formula, which gives the rank of an elliptic surface in terms of a weighted average of fibral Frobenius trace values. The aim of this article is to extend their result to the case of elliptic threefolds, and deduce, from Tate's conjecture, a Nagao-type formula for the rank of an elliptic threefold E. This will require a two-pronged approach: on the one hand, we need some cohomological results in order to derive a Shioda-Tate-like formula for elliptic threefolds; on the other, we compute an "average" number of rational points on the singular fibers and relate this to the action of Galois on those fibers.

Abstract: Background: After achieving morphological remission, existence of few number of leukemic cells in the patient’s blood represents the minimal residual disease (MRD) and its monitoring helps in evaluating early treatment response and future relapse. Patients and methods: Eighty seven newly diagnosed (B-ALL) cases were enrolled in the present study in the time period from October 2013 to October 2016. A panel of 4 monoclonal antibodies (CD10FITC, CD19PE, CD34PercP and CD45APC) were defined at diagnosis and after morphological remission for tracing of minimal residual disease (MRD). Results: Eighty seven newly diagnosed B-ALL cases were included in the present study of which 73 (84%) showed positive expression to CD45 in combination with (CD10, CD19 and CD34) at diagnosis, which allow us to use this combination for further assessment of MRD after morphological remission. In our study 65% of patients had negative MRD (<0.01), while 35% of patients had positive MRD (≥0.01). The DFS and OS for patients with MRD-ve were significantly higher than those with MRD + ve (P = 0.01 & P = 0.04) respectively. Conclusion: MRD detection by flow cytometry using the combination of CD45 with CD10, CD19 & CD34 is an easy and reliable method. Patients with positive MRD are at higher risk of relapse and have inferior overall survival rates compared to those with MRD-ve. Future studies focusing on treatment intensification for the group of patients with +ve MRD aiming to improve the treatment outcome are warranted.
Prevalence and antimicrobial resistance pattern of bacterial meningitis in Egypt
Lamyaa Shaban, Rania Siam
Annals of Clinical Microbiology and Antimicrobials , 2009, DOI: 10.1186/1476-0711-8-26
Abstract: Emerging infectious diseases will always pose a world threat because of the continuous battle with pathogens that undergo antigenic changes to escape our immune system, and resist antimicrobial treatment. Communicable diseases are particularly challenging in developing countries because of poor-socioeconomic conditions that facilitate the spread of the pathogens and the abuse of antimicrobial therapy that results in emerging antimicrobial resistant strains, that are resistant to conventional antimicrobial treatments and possibly vaccines. This article addresses communicable diseases that are either transmitted through airborne mechanisms or contact including droplets and discharge from nose and throat. The epidemiology of three bacterial meningitis agents will be reviewed with emphasis on prevalence, antibiotic resistance and serotypes, to provide the platform for effective treatment and vaccine strategies in the region. Streptococcus pneumoniae is a leading causative agent of diverse infections. In Egypt, it was recently described as the leading cause of bacterial meningitis [1,2] skewing the epidemiology from Neisseria meningitidis, which was previously reported as the major etiological agent [3-6]. Acute respiratory infections caused by S. pneumoniae are frequently reported, yet more recent data are needed to form a comprehensive and updated understanding of serotype distribution and antimicrobial resistance pattern in the region [1,7]. A few studies addressed pulmonary infection from S. pneumoniae [8,9], with the majority of the studies addressing pneumococcal meningitis. Reports on the serotypes of isolates obtained during the studies of pneumococcal meningitis represent a fraction of all the serotypes causing different forms of pneumococcal diseases [7]. Additionally, the prevalent serotype distribution had shown variation along different studies conducted at different time intervals [7,10,11]. In order to assess effectively the epidemiology of the diseases fo
