Abstract: Introduction: Peripartum cardiomyopathy (PPCM) is a common clinical condition in northern Nigeria. This study aimed to determine the prevalence and characteristics of PPCM among women with heart failure referred for echocardiography. Materials and Methods: This is a retrospective study of 401 women managed for heart failure referred for echocardiography between October 2016 and September 2017. Their reports were analyzed for demographic and echocardiographic parameters. Results: The mean age of the 401 individuals studied was 41.28 ± 16.25 years. The commonest cause of heart failure was PPCM, accounting for 256 (69.5%), followed by hypertension 79 (19.7%) and rheumatic heart disease (RHD) 24 (5.9%). Conclusion: PPCM is a common and important cause of heart failure among women in Northern Nigeria.

Abstract:
Introduction: Sickle cell disease (SCD) is chronic, inherited haemoglobin disorder, associated with chronic tissue ischemia which may adversely affect any organ system. Chronic anaemia in SCD results in cardiac chamber dilatation with compensatory increase in left ventricular mass and varying degree of diastolic dysfunction that has been a strong independent predictor of mortality in patients with SCD. There is paucity of echocardiographic studies on adults Nigerians with SCD. This study therefore, aimed to assess left ventricular systolic and diastolic function among sickle cell disease patients in Kano State, North-Western Nigeria. Methods: The study was cross-sectional and comparative conducted at the SCD clinic and Medical/outpatient (MOP) clinic of Murtala Muhammad Specialist Hospital (MMSH), on eligible patients aged 13 years and above. One hundred patients with SCD (HbSS) were recruited as the study group while 100 non SCD (HbAA) patients, matched for age and sex served as controls. Left and right atrial and ventricular dimensions, left ventricular (LV) wall thickness, LV mass index and LV contractility variables were obtained. Parameters of LV diastolic function were also evaluated. Results: There were increases in the left atrial and left ventricular dimensions, left ventricular volumes and left ventricular mass (LVM) of the SCD patients. LV ejection fraction was equivalent, though there was evidence of left ventricular diastolic dysfunction in up to 36%. Conclusion: Left ventricular diastolic dysfunction may complicate cases adults with SCD.

Abstract: Background: There is paucity of data on cardiovascular disease (CVD) risk factors among stroke patients in our population. This study aimed at assessing CVD risk factors amongst stroke patients compared with apparently healthy controls. Methods: This was a case-control study conducted at Aminu Kano Teaching Hospital Kano. One hundred stroke subjects were consecutively recruited and compared with 100 age and sex matched controls. The CVD risk factors assessed were hypertension, diabetes mellitus, dyslipidemia, obesity, cigarette smoking, alcohol consumption, socioeconomic status (SES), increased age, male gender and Human Immunodeficiency Virus (HIV) status. Results: Mean age was 56.4 ± 15.8 years for cases and 54.5 ± 15.4 years for controls (p = 0.39), and 53% of the former and 52% of the latter were males (p = 0.887). The most prevalent CVD risk factor was hypertension, found in 71% of cases and 42% of the controls, (p = 0.01). All heart diseases were found in 70% of cases and 21% of controls (p < 0.001), and hypertensive heart disease (HHD) was the commonest, found in 55% of cases and 18% of controls (p < 0.001). Dyslipidemia was found in 53% of cases and 37% of the controls (p = 0.023), diabetes mellitus/hyperglycemia in 23% of the cases and 6% of the controls (p = 0.01), history of transient ischemic attack (TIA) in 19% of cases and 1% of the controls (p = 0.01), while atrial fibrillation was found in 9% of cases only. Other risk factors were uncommon. Conclusion: The most frequent CVD risk factors among Nigerians with stroke were systemic hypertension, heart diseases, male sex and dyslipidemia, while HIV and other risk factors were uncommon. Thus medical attention and public enlightenment should focus on the common ones as detected in this study.

Abstract: The filament of cape Ghir is characterized by a spatial and temporal variability relating to circulation of the water masses of the zone and current velocity of canaries current. The activity of resurgences of cape Ghir appears from April, intensifies during August and June and still persists in October during 2009. During the season of summer and autumn, the filamentous structure is marked by the presence of an activity of important resurgences. In August, the filament is restricted on one branch and appears in limited area of cape Ghir. In autumn, the filament structure fellow several branches toward different directions between cape Ghir and cape Sim.
It’s for the Greater Good: Perspectives on Maltreatment during Labor and Delivery in Rural Ghana  [PDF]

Abstract:

Aim: Encouraging women to deliver in facility settings is one strategy to improve maternal and neonatal outcomes in the developing world. However, in much of sub-Saharan Africa, fewer than half of pregnant women deliver in health facilities. Fear of maltreatment during labor and delivery has been shown to be one barrier to facility delivery, yet previous studies have focused solely on reports from women, rarely seeking insights from practicing midwives. Method: All seven practicing midwives from a rural hospital in Ghana and ten pregnant women seeking antenatal care from the same hospital were recruited to participate in in-depth interviews regarding their perceptions of care during labor and delivery. A semi-structured interview tool and qualitative field interviewing approach were utilized. All interviews were audio taped, transcribed, and analyzed using NVivo 9.0. Results: Respondents described situations that precipitate abuse during facility deliveries, yet not all abuse was seen as acceptable. Two overarching themes emerged: 1) The interaction between midwives and their patients is analogous to a mother/daughter relationship, including both a knowledge imbalance and the need for disciplinary action when necessary; and 2) Midwives feel a strong sense of responsibility for the delivery outcomes and as a result, they will do whatever it takes to deliver a live baby to a healthy mother. Hitting, yelling, and neglecting women were reported as common occurrences in the labor and delivery ward. However, each was undertaken to encourage women to do what was needed to deliver safely. Conclusion: These findings suggest that the issue of patient maltreatment in low-resource labor and delivery settings is complex and may be undertaken in what is perceived to be the laboring woman’s best interest. The exploration of alternative strategies to facilitate labor and delivery is warranted, as well as the provision of adequate support and resources for practicing midwives in rural settings.

Abstract: A mathematical model of HIV transmission dynamics is proposed and analysed. The population is partitioned into five compartments of susceptible S(t), Infected I(t), Removed R(t), Prevented U(t) and the Controlled W(t). Each of the compartments comprises of cohort of individuals. Five systems of nonlinear equations are derived to represent each of the compartments. The general stability of the disease free equilibrium (DFE) and the endemic equilibrium states of the linearized model are established using the linear stability analysis (Routh-Hurwitz) method which is found to be locally asymptotically stable when the infected individuals receive ART and use the condom. The reproduction number is also derived using the idea of Diekmann and is found to be strictly less than one. This means that the epidemic will die out.
Physical Network Approach Applied to Wind Turbine Modeling with Simscape Language  [PDF]
Elhaini Jamila, Saka Abdelmjid
Open Journal of Modelling and Simulation (OJMSi) , 2014, DOI: 10.4236/ojmsi.2014.22010
Abstract: Model-Based Design is an efficient and cost-effective way to develop controls, signal processing, image processing, communications, mechatronics, and other embedded systems. Rather than re-lying on physical prototypes and textual specifications, Model-Based Design uses a system model as an executable specification throughout development. It supports system- and component-level design and simulation, automatic code generation, and continuous test and verification. This paper is focused firstly on the so-called model-based design and aims at presenting an up-to-date state of the art in this important field. Secondly, it develops a model based design for wind energy systems. Mathematical formulations and numerical implementations for different components of wind energy systems are highlighted with Simscape language. Finally, results are derived from simulations.

Wiem Guissouma, Jamila Tarhouni
Journal of Water Resource and Protection (JWARP) , 2015, DOI: 10.4236/jwarp.2015.711070
Abstract: This paper presents a fluoride health risk characterization approach to identify the hyper-sensitive population of adverse effect like tooth decay, dental fluorosis and skeletal fluorosis. In this context, a sampling campaign has been done over 100 Tunisian water consumption points (tap). Laboratory analysis results show that the quality of drinking water is affected by high fluoride concentration level exceeding 2 mg·L-1. Over these samples, 7% of them present non-compliant with the Tunisian national standard (NT09.14) and the international guidelines (World Health Organization recommendations, WHO). The overtake cases are located essentially in southern Tunisian areas, i.e. Medenine, Gabes, Gafsa and Tataouine. One can highlight that groundwater, in these southern Tunisian areas, are naturally rich of fluoride. This is because of the aquifers geological and fossil nature. However, commonly northern and central Tunisian areas are characterized by low fluoride concentration level below 0.1 mg·L-1. These undertaken cases don’t meet the water quality requirement defined by WHO.

Cybrarians Journal , 2006,
Abstract: The new technologies of information and the communication brought with the electronic edition a set of changes that influenced the writing and the book in its shapes as well as in its contents. The fact to speak of reading practices and their evolutions take us in the same way to speak of the book and his/her/its evolution through history. the research on the topic is only an attempt of assessment of the era of information of which we live in order to put in evidence the existing changes to analyze them then and to understand them
Exotic Particles and $w_\infty$-Algebras in Two- and High-Dimensional Spaces
Jamila Douari
Physics , 2005, DOI: 10.1142/S0217751X0603134X
Abstract: We construct a set of noncommuting translation operators in two and high-dimensional lattices. The algebras they close are $w_{\infty}$-algebras. The construction is based on the introduction of noncommmuting elementary link operators which link two neighborhood sites in the lattice. This kind of operators preserve the braiding nature of exotic particles living basically in two-dimensional space.
