Overview of Post-Stroke Epilepsy  [PDF]
Wadi Bnouhanna, Amal Satté, Jamal Mounach, Hamid Ouhabi
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105705
Abstract:
Stroke is the most common cause of seizures, symptomatic epilepsy, and status epilepticus in elderly. Symptomatic stroke-related seizures symptoms are dependent on lesions topography. All types of focal seizures can be observed. Many clinical studies make a distinction between early (within 7 to 14 days of stroke onset) and late (beyond 14 days of stroke onset) seizures based on presumed physiopathological differences. The diagnosis of a seizure during the acute phase of a stroke can be difficult in the absence of a witness when there are disorders of vigilance and speech. The use of antiepileptic drugs is discussed in all cases. New antiepileptic drugs appear to be most appropriate. The aim of this study is to present an overview of the epidemiological, clinical and therapeutic features of vascular epilepsy based on meta-analyses and the more recently published expert recommendations.
On the Maximum Likelihood and Least Squares Estimation for the Inverse Weibull Parameters with Progressively First-Failure Censoring  [PDF]
Amal Helu
Open Journal of Statistics (OJS) , 2015, DOI: 10.4236/ojs.2015.51010
Abstract: In this article, we consider a new life test scheme called a progressively first-failure censoring scheme introduced by Wu and Kus [1]. Based on this type of censoring, the maximum likelihood, approximate maximum likelihood and the least squares method estimators for the unknown parameters of the inverse Weibull distribution are derived. A comparison between these estimators is provided by using extensive simulation and two criteria, namely, absolute bias and mean squared error. It is concluded that the estimators based on the least squares method are superior compared to the maximum likelihood and the approximate maximum likelihood estimators. Real life data example is provided to illustrate our proposed estimators.

Amal A. Kokandi
Journal of Cosmetics, Dermatological Sciences and Applications (JCDSA) , 2013, DOI: 10.4236/jcdsa.2013.33A2006
Abstract:

Objectives: Acne is a common skin disease especially in adolescents and young adults. Several pathogenetic factors are implicated in causing the disease. Typically acne flares and remits in its course. Several factors can cause flares. The aim of this study was to assess the perceived factors of acne flares and the idea of sun creams causing skin darkening. Methods: A questionnaire study of the perceived factors in causing acne flares was studied in university female students. These included food, stress, hygiene and menstrual periods. In addition, the effect of sun creams on causing skin darkening was asked. Results: Food was implicated by 43.2% of patients. Stress and menstrual periods were thought to exacerbate acne by more than 70% of patients while 80% of patients did not think bad hygiene worsened acne. 40% of patients thought the use of sun creams cause skin darkening. Conclusion: More controlled studies are needed to explore the effect of food on acne. Dermatologists need to explain the benefit of using sun creams especially to acne patients while using standard treatments.

Soil Salinity Mapping and Monitoring in Arid and Semi-Arid Regions Using Remote Sensing Technology: A Review  [PDF]
Amal Allbed, Lalit Kumar
Advances in Remote Sensing (ARS) , 2013, DOI: 10.4236/ars.2013.24040
Abstract:

Soil salinity is a serious environmental problem especially in arid and semiarid areas. It either occurs naturally or is human-induced. High levels of soil salinity negatively affect crop growth and productivity leading land degradation ultimately. Thus, it is important to monitor and map soil salinity at an early stage to enact effective soil reclamation program that helps lessen or prevent future increase in soil salinity. Remote sensing has outperformed the traditional method for assessing soil salinity offering more informative and professional rapid assessment techniques for monitoring and mapping soil salinity. Soil salinity can be identified from remote sensing data obtained by different sensors by way of direct indicators that refer to salt features that are visible at the soil surface as well as indirect indicators such as the presence of halophytic plant and assessing the performance level of salt-tolerant crops. The purposes of this paper are to 1) discuss some soil salinity indicators; 2) review the satellite sensors and methods used for remote monitoring, detecting and mapping of soil salinity, particularly in arid and semi-arid regions; 3) review various spectral vegetation and salinity indices that have been developed and proposed for soil salinity detection and mapping, with an emphasis on soil salinity mapping and assessment in arid and semi-arid regions; and 4) highlight the most important issues limiting the use of remote sensing for soil salinity mapping, particularly in arid and semi-arid regions.

Characteristics and Risk Factors Attributed to Coronary Artery Disease in Women Attended Health Services in Gaza-Palestine Observational Study  [PDF]
Yehia Abed, Amal Jamee
World Journal of Cardiovascular Diseases (WJCD) , 2015, DOI: 10.4236/wjcd.2015.51002
Abstract: Coronary artery disease (CAD) is the leading cause of death in both sexes worldwide, and becomes number one killer in women due to many factors including increase in traditional risk factors, delays in apparition of symptoms, under estimation of diagnosis test and treatment. Our study aims to identify risk factors for coronary artery disease among women with chest pain underwent coronary angiography during years (2010-2013) in cardiology center. The study design is an observational among 688 women-aged 32 - 96 years; the mean age of our study population is 61 years. Risk factors are abstracted from patients’ files. Women with documented coronaries disease tend to be older, have higher, systolic blood pressure, serum level of triglyceride, and impaired clearance creatinine. 59.4% of them are menopause with higher prevalence of hypertension and diabetes (58.6% and 63.6%). Significant positive association is found in women with myocardial infarction, unstable angina, stable angina and presence of obstructive coronary artery disease respectively (89.6%, 82.3%, 59.1%) in opposite women presented with atypical chest pain have high prevalence of normal coronaries (95.7%). About 57.6% have more than three risk factors, and 55.3% are obese or overweight. In addition, 42.1% of them have impaired systolic function. We conclude that cardiovascular risk factors are highly prevalent among Palestinians women in Gaza and the combination of risk factors is common. Interventions to minimize CAD in our population are needed.

Amal Kamal Mohamed Shamseldin
Journal of Building Construction and Planning Research (JBCPR) , 2016, DOI: 10.4236/jbcpr.2016.41004
Abstract: The idea behind this work is developing an adaptive method for the environmental assessment of buildings, to configure different versions according to the variables affecting them (spatial, temporal and associated with building characteristics) to suit different evaluated projects. This method may be applied using an electronic tool, which is in a development stage. Amending different assessment versions of the adaptive method is done by including the variables effect, according to set of steps, such as modifying the formulation of the assessment items, adjusting their estimation weights, and amending their achievement evaluation levels and their returned scores. When using the adaptive method, the assessment result of a building using a certain version differs from the results using other versions, even in the same country, so configuring an appropriate version due to the variables affecting the assessment helps getting more accurate results than the ones currently provided. The main goal of that research is to introduce the adaptive method that is proposed to ensure a fairer assessment results from the perspective of Green Architecture, and allow a more credible and accuracy of results comparison according to the environmental performance of buildings. The researcher analyzed the different main features she used in developing the adaptive method, the Comparative aspects between it and the current assessment methods, and the expected reached advantages from its usage. The paper arrived to the importance of adapting the environmental assessment of buildings according to the different affecting variables, and recommended developing the adaptive method and its tool to the stage of application to benefit its advantages.
Advertisement Spending and Income: An Aggregative Analysis  [PDF]
Baiding Hu, Amal Sanyal
Theoretical Economics Letters (TEL) , 2016, DOI: 10.4236/tel.2016.62040
Abstract: Existing studies tend to investigate cross-sectional relations between GDP and advertisement at the firm or industry level. The present study focuses on the long-run relation between GDP and aggregate advertisement spending using United States data for the period 1900-2007. Granger causality tests indicate the temporal precedence of GDP. A cointegration analysis shows that, as GDP increases, it causes advertisement spending to increase at a rate faster than its own growth. Faster growth relative to GDP is accompanied with a negative autonomous trend of advertisement spending. This trend appears consistent with the continuous technical progress in advertisement.
Assessment of Minimizing the Environmental Functions Conflict in Buildings  [PDF]
Amal Kamal Mohamed Shamseldin
Journal of Building Construction and Planning Research (JBCPR) , 2016, DOI: 10.4236/jbcpr.2016.42008
Abstract: Some building components are responsible for achieving more than one environmental function, these functions are usually of different requirements that can never be done by the same actions, and they are usually connected to changeable internal and external environment characteristics that vary among them. Minimizing the conflict of achieving the different environmental functions is an important challenge for all designers. Achieving a continuous thermal and optical comfort in an internal building space using the same window is an example of this challenge, as they have different requirements that may be sometimes contrary. It should be notable that there are a lot of recent technologies that may be used to find solutions for such a conflict. The Environmental Assessment Methods of Buildings appeared to set the principles of the optimum relation between buildings and their environment, they also could be used to encourage designers to reach the best environmental relations, and award them by main or additional assessment points. The research paper proposes to use the Environmental Assessment Methods of Buildings to assess the building ability of minimizing its environmental functions achievement conflict. This proposal depends on determining the inconsistency assessment items that depend on common building components to be achieved, and then determining the time periods that these items are achieved together within, to indicate the time periods without conflicting. Thus, the paper aims to raise the building environmental value in the assessment when the designer succeeds to minimize the expected conflict of the building environmental functions.
