Samsu Udayana Nurdin, Mubarak Ismail, Yaktiworo Indriani, Reni Zuraida
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105371
Abstract:
Objectives: There is currently no data on the prevalence of obesity and li-pid profile as well as nutrition and food intake of elementary schoolchildren in Bandar Lampung city. Therefore, the aim of this study was to investigate obesity prevalence and dyslipidemia in children. Design, setting, and participants: Cross-sectional study on grade 4 school children in Bandar Lampung Indonesia (n = 392). Outcome measures: Characteristics of schoolchildren and their family, nutrition, fruits, and vegetable intakes, and physical activities, body mass index (BMI) and lipid profile were collected from 392 children of grade 4 from five elementary schools in Bandar Lampung. One-way ANOVA and correlation analysis were applied with BMI and lipid profiles as dependent variables. Results: The incidence of undernutrition (7.7%) was lower than the incidence of overnutrition (26.3%). Energy, protein and fat daily intake were higher for children with higher BMI, however, carbohydrate consumption was not affecting the BMI. Obese children had more vegetable and fruit intake than wasting children and spent 30 minutes less in physical activity than normal children. Lipid plasma of schoolchildren was considered as acceptable or borderline high except for the TG of obese children in the high category. Conclusions: Prevalence of obesity was high and being obese was more likely to result in higher TG and lower HDL. The lifestyle of obese schoolchildren was characterized by a high intake of energy, protein, and fat and lower physical activities. Encouraging schoolchildren to modify their lifestyles is recommended.
Basidiobolomycosis of the Colon Masquerading as Stenotic Colon Cancer
M. Ezzedien Rabie,Ismail El Hakeem,Mubarak Al-Shraim,M. Saad Al Skini,Salim Jamil
Case Reports in Surgery , 2011, DOI: 10.1155/2011/685460
Abstract: Basidiobolus ranarum is a widespread saprophyte fungus with pathogenic potential. It affects mainly the subcutaneous tissues of the trunk and limbs. Relatively recently, occasional reports of gastrointestinal basidiobolomycosis appeared in the literature. Due to the rarity of the condition and the nonspecific presenting features, the correct diagnosis is usually hard to reach. In this paper, we describe the clinical course of an otherwise healthy female, who presented with a colonic mass. She received subtotal colectomy followed by oral itraconazole, with successful outcome.
Review of Handover Mechanisms to Support Triple Play in Mobile WiMAX
Ben-Mubarak Mohammed,Mohd. Ali Borhanuddin,Noordin Nor,Ismail Alyani
IETE Technical Review , 2009,
Abstract: Handover (HO) mechanism is one of the critical operations in mobile WiMAX. It takes place when a mobile -station (MS) moves from a serving base station (BS) to another BS. However, the HO latency in mobile WiMAX is still an issue that may affect continuity of real-time application sessions such as Voice over Internet Protocol (VoIP). This paper presents performance comparison of some HO mechanisms for real-time applications in mobile WiMAX, including HO, cross-layer HO, pre-coordination HO, passport HO mechanisms and fast intra-network and cross-layer HO (FINCH). Each one of these mechanisms reduces HO latency, especially during downlink traffic; however, they still produce insufficient HO latency during uplink traffic. Except for FINCH, they do not consider the scenario of HO between BSs that belong to different access service network-gateways (ASN-GWs) or to different connectivity service networks (CSNs); these two cases cause extra layer 3 (L3) HO latency.

International Journal of Quality, Statistics, and Reliability , 2012, DOI: 10.1155/2012/245910
Abstract: This paper considers the estimation problem for the Frèchet distribution under progressive Type II censoring with random removals, where the number of units removed at each failure time has a binomial distribution. We use the maximum likelihood method to obtain the estimators of parameters and derive the sampling distributions of the estimators, and we also construct the confidence intervals for the parameters and percentile of the failure time distribution.
MIXTURE OF TWO FR CHET DISTRIBUTIONS:PROPERTIES AND ESTIMATION
Mohamed Mubarak
International Journal of Engineering Science and Technology , 2011,
Abstract: The Mixture models play a vital role in many practical applications. In this paper, we discuss the mixture model of two Frèchet distributions (MTFD). First, some properties of the model with hazard function are discussed. In addition, the estimates of the unknown parameters via the EM algorithm are obtained. The performance of the findings in the paper is showed by demonstrating some numerical illustration through Monte Carlo simulation.
Ultrastructure of Sperm Tail Differentiation of the Lizard Stenodactylus dorie (Squamata, Reptilia)
Mohammed Mubarak
Journal of Biological Sciences , 2006,
Abstract: The ultrastructural features of the sperm tail differentiation in the lizard, Stenodactylus dorie have been described. The initial event was the caudal migration of the centrioles followed by implantation of the proximal centriole in the nuclear fossa and extension of the distal centriole to form the microtubular axoneme. Thereafter, the neck region and middle, main and end tail pieces were developed. The later three tail pieces along their length encompassed the axonemal core which revealed the typical 9+2 arrangement of microtubules. The axonemal core in the middle piece was enveloped within two successive sheaths, the mitochondrial and fibrous ones while in the main piece it was only encircled by the fibrous sheath. End piece only revealed the existence of an axonemal core surrounded by plasmalemma of the fully differentiated spermatid.
Histopathology of Toxicity Induced in Broiler Chickens by Excess Sodium Compounds
Muhammad Mubarak
Journal of Biological Sciences , 2004,
Abstract: An experimental study was conducted to investigate the effects induced in broiler chickens by excess sodium from different compounds, namely sodium chloride (SC), sodium bicarbonate (SB) and sodium phosphate (SP), added to the drinking water. Higher and lower doses of the these compounds were administered to the treated birds. All the high-dosed birds died during the first 10 days post-treatment. Histological examination revealed significant myocardial alterations in all groups, however these were more pronounced in the SC-group while SB-and SP-groups showed marked renal changes. Erythrocyte deformability was decreased in all treated birds and probably was related to the increased mean corpuscular volume (MCV) of erythrocytes.

Introduction Recently, the extreme value distribution is becoming increasingly important in engineering statistics as a suitable model to represent phenomena with usually large maximum observations. In engineering circles, this distribution is often called the Frèchet model. It is one of the pioneers of extreme value statistics. The Frèchet (extreme value type II) distribution is one of the probability distributions used to model extreme events. The generalization of the standard Frèchet distribution has been introduced by Nadarajah and Kotz [1] and Abd-Elfattah and omima[2]. There are over fifty applications ranging from accelerated life testing through to earthquakes, floods, rain fall, queues in supermarkets, sea currents, wind speeds, and track race records, see Kotz and Nadarajah [3]. Censoring arises in a life test when exact lifetimes are known for only a portion of test units and the remainder of the lifetimes are known only to exceed certain values under an experiment. There are several types of censored test. One of the most common censoring schemes is Type II censoring. In a Type II censoring, a total of units is placed on test, but instead of continuing until all units have failed, the test is terminated at the time of the th unit failure. Type II censoring with different failure time distribution has been studied by many authors including Mann et al. [4], Lawless [5], and Meeker and Escobar [6]. If an experiment desires to remove live units at points other than the final termination point of the life test, the above described scheme will not be of use to experimenter. Type II censoring does not allow for units to be lost or removed from the test at points other than the final termination point see Balakrishnan and Aggarwala [7, Chapter 1]. A generalization of Type II censoring is progressive Type II censoring. Under this scheme, units are placed on test at time zero, and failure are going to be observed. When the first failure is observed, of surviving units are randomly selected, removed, and so on. This experiment terminates at the time when the th failures is observed and
Repetitive Control Uncertainty Conditions in State Feedback Solution  [PDF]
Muhammad Alsubaie, Mubarak Alhajri, Tarek Altowaim
Intelligent Control and Automation (ICA) , 2018, DOI: 10.4236/ica.2018.94008
Abstract: Repetitive Control (RC) designed with state feedback that includes past error feedforward and current error feedback schemes for linear time-invariant systems is reintroduced. Periodic disturbances are common within repetitive systems and can be represented with a time-delay model. The proposed design focuses on isolating the disturbance model and finding the overall transfer function around the delay model. The use of the small gain theorem around the delay model assures disturbance accommodation if stability conditions are achieved. This paper reintroduces the designed RC controller within the state feedback in the presence of both past error and current error structures. Robustness conditions are investigated and set to enhance system performance in the presence of modelling mismatch, which represents the novel contribution in this paper. Simulations demonstrate the advantages of the robust conditions obtained while improving system performance for dynamic perturbations.
