Abstract: the cusp of carabelli trait was first described by carabelli in 1842. if present, it is seen on the mesial aspect of the mesiopalatal cusp of the deciduous maxillary second molar or permanent maxillary first, second and third molar. the level of expression varies from a mere pit or groove to a well developed cusp. the objective of this study was to assess the prevalence of this trait in abha secondary school boys in the age range of 15-20 years. 917 subjects without caries or fillings (or missing) in permanent upper first (16/26) and second molars (17/27) were selected out of the 3408 students examined. the trait was recorded as present or absent in 16/26 and 17/27 only as most of the students had erupted premolars and unerupted third molars. the trait was present in 41.7% of the population out of which 82.2% were seen on 16/26 bilaterally. it showed more predilection to permanent maxillary right first molar - 39.4% than permanent maxillary left first molar - 35.8%. only 3.1% of the population had the trait on 17/27. these results are in contrast with the prevalence studies carried out in riyadh - 57.6% and jeddah - 58.7%. nevertheless, it places the saudi population in moderate ct prevalence group.
Difficulties in Treatment and Management of Epilepsy and Challenges in New Drug Development
Abdul Wahab
Pharmaceuticals , 2010, DOI: 10.3390/ph3072090
Abstract: Epilepsy is a serious neurological disorder that affects around 50 million people worldwide. Almost 30% of epileptic patients suffer from pharmacoresistance, which is associated with social isolation, dependent behaviour, low marriage rates, unemployment, psychological issues and reduced quality of life. Currently available antiepileptic drugs have a limited efficacy, and their negative properties limit their use and cause difficulties in patient management. Antiepileptic drugs can provide only symptomatic relief as these drugs suppress seizures but do not have ability to cure epileptogenesis. The long term use of antiepileptic drugs is limited due to their adverse effects, withdrawal symptoms, deleterious interactions with other drugs and economic burden, especially in developing countries. Furthermore, some of the available antiepileptic drugs may even potentiate certain type of seizures. Several in vivo and in vitro animal models have been proposed and many new antiepileptic drugs have been marketed recently, but large numbers of patients are still pharmacoresistant. This review will highlight the difficulties in treatment and management of epilepsy and the limitations of available antiepileptic drugs and animal seizure models.
Bridging Literature and Linguistics
Abdul Wahab
TEFLIN Journal , 2002,
Abstract: : Two majors linguistics and literature in the schools of letters both in the state and private universities throughout Indonesia are commonly separated sharply. Courses of literature in the Department of Linguistics are offered minimally, such that the students of linguistics are not given a conducive atmosphere to express their literary appreciation. Likewise, courses of linguistics in the Department of Literature are very restricted, so that the students of literature are unable to analyze literary works from the points of linguistic view. This paper tries to bridge linguistics and literature. The attempt to bridge linguistics and literature is based on three postulates: (I) literature consists of linguistic objects designed with an artistic end, (2) linguistic objects are formal objects, and (3) a formal account of linguistic object designed with an artistic end approximates a formal account of that artistic design. Two major directions in the approaches and emphases will be presented in the paper exogenous and endogenous. Exogenous approach tries to search for adequate description of (1) poetic language as contrasted with ordinary language, (2) language of a particular author contrasted with that of other authors, and (3) a particular literary work contrasted with other works of the same author. This part touches upon three areas of exogenous approach isolation, description, and characterization. Endogenous, on the hand, is based upon an assumption that a writer exhibits, probably without realizing it, certain systematic preferences for particular aspects of linguistic patterns. Planning a bridge between linguistics and literature is by no means without problems. Therefore, this paper also presents some possible solutions.

Stability and Resolution Analysis of Topological Derivative Based Localization of Small Electromagnetic Inclusions
Abdul Wahab
Mathematics , 2014,
Abstract: The aim of this article is to elaborate and rigorously analyze a topological derivative based imaging framework for locating an electromagnetic inclusion of diminishing size from boundary measurements of the tangential component of scattered magnetic field at a fixed frequency. The inverse problem of inclusion detection is formulated as an optimization problem in terms of a filtered discrepancy functional and the topological derivative based imaging functional obtained therefrom. The sensitivity and resolution analysis of the imaging functional is rigorously performed. It is substantiated that the Rayleigh resolution limit is achieved. Further, the stability of the reconstruction with respect to measurement and medium noises is investigated and the signal-to-noise ratio is evaluated in terms of the imaginary part of free space fundamental magnetic solution.

Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.66079
Abstract: The purpose of this study was to examine the relationship between organizational citizenship behavior with organizational commitment and equity perception of secondary school administrators in Zahedan. The descriptive-correlational method was applied. The population of the study included all secondary school administrators in Zahedan in 2013-2014 academic year (N = 92). Using the sample size formula, 78 administrators were selected as respondents. Data collection instruments included Podsakoff’s Organizational Citizenship Behavior Inventory (2000), Strone’s Equity Perception Inventory (1996) and Steers and Porter’s Organizational Commitment Questionnaire (1998). The content validity of the questionnaires was checked and their reliability was estimated using Cronbach’s alpha coefficient which was 0.93, 0.83 and 0.72, respectively. To investigate the research questions, Pearson correlation coefficient and stepwise regression analysis were used. Based on the findings of the research, there was a significant positive correlation between organizational citizenship behavior and both organizational commitment and equity perception of secondary school administrators in Zahedan. Considering the components of organizational citizenship behavior, there was a significant positive relationship between altruism and conscientiousness and equity perception, and between conscientiousness, sportsmanship, civic virtue and respect and organizational commitment. Moreover, there was a significant negative correlation between equity perception and organizational commitment. With regard to the components of organizational citizenship behavior, conscientiousness could predict equity perception and tribute could predict organizational commitment.

Abstract: The cusp of Carabelli trait was first described by Carabelli in 1842. If present, it is seen on the mesial aspect of the mesiopalatal cusp of the deciduous maxillary second molar or permanent maxillary first, second and third molar. The level of expression varies from a mere pit or groove to a well developed cusp. The objective of this study was to assess the prevalence of this trait in Abha Secondary School boys in the age range of 15-20 years. 917 subjects without caries or fillings (or missing) in permanent upper first (16/26) and second molars (17/27) were selected out of the 3408 students examined. The trait was recorded as present or absent in 16/26 and 17/27 only as most of the students had erupted premolars and unerupted third molars. The trait was present in 41.7% of the population out of which 82.2% were seen on 16/26 bilaterally. It showed more predilection to permanent maxillary right first molar - 39.4% than permanent maxillary left first molar - 35.8%. Only 3.1% of the population had the trait on 17/27. These results are in contrast with the prevalence studies carried out in Riyadh - 57.6% and Jeddah - 58.7%. Nevertheless, it places the Saudi population in moderate CT prevalence group. La cúspide o tubérculo de Carabelli, fue descrita por primera vez por Carabelli en 1842. Si está presente, se observa en la cara mesial de la cúspide mesio-palatina del segundo molar superior permanente o temporal, segundo y tercer molar permanentes. El nivel de expresión varía desde una simple fosa a una cúspide bien desarrollada. El objetivo de este estudio fue evaluar la prevalencia de este tubérculo en los alumnos de escuelas secundarias de Abha en el rango de edad entre 15-20 a os. 917 sujetos sin caries ni obturaciones (o extracción) en los primeros (16/26) y segundos (17/27) molares maxilares permanentes fueron seleccionados entre 3408 alumnos examinados. El tubérculo se registró como presente o ausente en 16/26 y 17/27 de los molares, la mayoría de los estudiantes tenían erupcionados los premolares y no erupcionados los terceros molares. El tubérculo estuvo presente en el 41,7% de la población estudiada, fuera de la cual se observó en el 82,2% sobre 16/26 bilateralmente. Hubo mayor predilección por el primer molar permanente del lado derecho, un 39,4%, en comparación al lado izquierdo, 35,8%. Sólo el 3,1% de la población tuvo el tubérculo sobre 17/27. Estos resultados contrastan con los estudios de prevalencia realizados en Riyadh con 57,6% y Jeddah con 58,7%. Sin embargo, coloca a la población de Arabia Saudita en el grupo de moderada prevalencia de
Necessity of Two More Space Lattices
Mohammad Abdul Wahab
Physics , 2009,
Abstract: Existing fourteen Bravais/space lattices are found to be inadequate for proper crystallographic representation and some conceptual understandings. The complicacies, confusions and ambiguities encountered in the representation of trigonal/rhomohedral and hexagonal lattices have been removed by suggesting the need of two more space lattices in the form of Hexagonal Close Packing (HCP) and Rhombohedral Close Packing (RCP) with appropriate justifications. Henceforth, these two lattices will be called as Wahab lattices and the sixteen lattices together as Bravais Wahab lattices (or space lattices as before). This finding will have immediate as well as far reaching implications.
Some Anisotropic Viscoelastic Green Functions
Elie Bretin,Abdul Wahab
Mathematics , 2011,
Abstract: In this paper, we compute the closed form expressions of elastody- namic Green functions for three different viscoelastic media with simple type of anisotropy. We follow Burridge et al. [Proc. Royal Soc. of London. 440(1910): (1993)] to express unknown Green function in terms of three scalar functions $\phi_i$, by using the spectral decomposition of the Christoffel tensor associated with the medium. The problem of computing Green function is, thus reduced to the resolution of three scalar wave equations satisfied by $\phi_i$, and subsequent equations with $\phi_i$ as source terms. To describe viscosity effects, we choose an empirical power law model which becomes well known Voigt model for quadratic frequency losses.

Abstract: This paper presents a preliminary study examining the potential influences of building design on bullying behavior and experiences, of a sample of Malaysia secondary school students. Bullying in school may be an early stage of the developmental sequence that serves as a strong predictor of delinquency and future crime. Through the discussion of findings in previous studies, environmental design approach is as one of the methods to bring down the level of crime in school. Crime Prevention through Environmental Design (CPTED) is an approach that uses environmental design as a tool to reduce crime from both the physical and the psychological aspects. The features of physical environment such as street layout, building design, lighting and physical decay can affect the occurrence and behaviour of criminals. The shortcomings in the physical environment could open up the opportunity for offenders. Thus, this study seeks to determine if there is a possibility that the actual physical environment in which students spend greater part of their day can affect behaviour, which in turn, can lead to violence in school. A survey was conducted at four secondary schools in Shah Alam, Selangor with a random sample of 406 students from Form 1, Form 2 and Form 3 involving the observation of 32 school blocks. Three principles of Crime CPTED were analyzed in the school environment. The results indicated that there is a significant difference in territoriality and school maintenance which results in the forming of the negative environment in the schools. It was found that this, in turn, affects the frequency of bullying occurring among the students in school.
