Multi-layer membrane filtration is a widely used technology for separating and purifying different components ofa liquid mixture. This technique involves passing the liquid mixture through a series of membranes with decreasing pore sizes, which allows for the separation of different components according to their molecular size. Thisstudy investigates the filtration process of a fluid through a two-dimensional porous medium designed forseawater desalination. The focus is on understanding the impact of various parameters such as the coefficientof friction, velocity, and the number of layers on filtration efficiency. The results reveal that the number of layersplays a crucial role in desalination, with an increase in layers leading to enhanced filtration quality, following apower law relationship. The study explores the influence of the coefficient of friction on filtration performance,emphasizing its significant effect on the number of particles filtered over time. Additionally, the role of the initialvelocity in filtration efficiency is examined, showing distinct effects at both high and low velocities. Biofouling isidentified as a factor influencing filtration, with an initial increase in filtered particles followed by a decline due toparticle accumulation in pores.

Advances in Aging Research 2013年第4期2卷 160-165页

作者： salma M. S. el Said Tomader Abd el Rahman ahmed K. Mortagy Marian Wagieh Mansour Geriatrics and Gerontology Department Faculty of Medicine Ain Shams University Cairo Egypt

OBJECTIVE: To estimate the effects of nocturia on quality of life (QoL) and to assess the associated effects of sleep problems. Background: Nocturnal urination (nocturia) is such a commonplace occurrence in the lives of many older adults that it is frequently overlooked as a potential cause of sleep disturbance. Methods: The current study was carried out to assess the prevalence of nocturia in elderly males and its impact on sleep quality and QoL. The study enrolled 200 elderly males aged 60 years old and above. All participants were recruited from geriatric clubs in Cairo. All participants in the study were subjected to: comprehensive geriatric assessment, American Urological Association (AUA) score used to measure the severity of nocturia ,assessment of sleep quality using Pittsburgh Sleep Quality Index (PSQI) and assessment of QoL using “SF-12 Short Form Health Survey”. Results: The study showed that the prevalence of nocturia in elderly males aged ≥60 years old was 68% with significant association between nocturia and diabetes mellitus, heart failure, stroke, prostatism, recurrent UTI and diuretic use. As regard sleep quality, the current study showed that the prevalence of poor sleep in the studied subjects is 70.5% with significant association between nocturia and poor sleep quality. Nocturia significantly affects sleep latency, sleep efficiency and daytime dysfunction, high significantly affecting sleep disturbance. Also diabetes mellitus, ischemic heart disease, heart failure, prostatism, recurrent UTI, osteoarthritis and diuretic use are significantly associated with poor sleep quality. As regard quality of life, the current study showed significant association between nocturia and physical and mental health components of HRQL in the univariate analysis. But after multivariate analysis, nocturia is not an independent risk factor for poor quality of life. Nocturia affects QoL through its effect on sleep quality which is an independent risk factor for poor ph

Volumetric Overload Shocks: Why Is Starling’s Law for Capillary Interstitial Fluid Transfer Wrong? The Hydrodynamics of a Porous Orifice Tube as Alternative

引用

Surgical Science 2016年第6期7卷 245-249页

作者： ahmed N. Ghanem salma A. Ghanem Retired Consultant Urologist Mansoura Egypt Guys & St. Thomas NHS Trust London UK

Based on clinical and experimental work two new types of volumetric overload shocks are reported: volumetric overload shock type one and type two depending on the type of fluid causing their induction. Volumetric overload shock type one is induced by sodium-free fluids such as glycine, glucose, mannitol and sorbitol and is characterized with acute dilutional hyponatraemia. Volumetric overload shock type 2 is induced with sodium-based fluids normal saline and plasma substitutes used for resuscitation of the critically ill and has no serological marker. It presents with the multiple vital organs dysfunction or failure syndrome or the adult respiratory distress syndrome. Hypertonic sodium is an effective treatment when given early adequately. The underlying pathophysiology is discussed. An alternative to Starling’s law for the capillary interstitial fluid transfer is given. Hydrodynamic of a porous orifice tube akin to capillary with a surrounding Chamber akin to the interstitial fluid space demonstrated a rapid dynamic magnetic field-like fluid circulation between the surrounding chamber and the lumen of the G tube that represent an adequate replacement for Starling’s law.

Today, information technology faces many challenges, and experiences exponential growth that is manifested in the great demand for machine accessible data. End-users are neither opt to learn programming language nor to express their queries in a language that they don’t comprehend. Clearly, software tools are designed and developed to assist end-users without being fluent in computer programming languages or non-native languages. End-users can simply issue instructions to the computer, or surf a GUI wizard program in their own mother tongue. In this paper, we describe a tool designed and implemented for database applications such as: a pay-roll system and medical applications. The tool works in two modes: （i） the set-up mode where it accepts the application schema and data dictionary, translates it into end-user native language, （ii） the operational mode where end-users may issue queries and create reports in their own native language （i.e. Arabic）. The tool is implemented in VB and it may be adapted to any application providing the intervening of database developer of any specific application.

Effects of Salicylic Acid on the Growth and Some Physiological Characters in Salt Stressed Tomato Plants （ Solanum L ycopersicum）

引用

Journal of Life Sciences 2011年第10期5卷 838-843页

Excessive soil salinity is an important constraint limiting the distribution of plants in natural habitats, and is an increasingly severe agricultural problem in arid and semi-arid regions. Higher salinity levels caused significant reduction in growth parameters like leaf area, leaf length and root and shoot dry weight. Salicylic acid （SA）, a plant phenolic is now considered as a hormone-like endogenous regulator, and its role in the defence mechanisms against biotic stressors has been well documented. In recent years its role has been widely investigated in abiotic stress （salinity, drought, water deficit and so on）. The aim of the present work was to study the effects of salicylic acid on growth and some physiological characters of salt stressed tomato plants. The presence of salicylic acid at low concentration （0.01 mM） in culture medium riched with NaCl 100 mM （6 g·L^-1） improves the tolerance of tomato cv. Golden Sunrise to salinity. This amelioration results in stimulation of growth and development of plants. The applied of SA in saline medium induce：（i） an increase in chlorophyll content; （ii） a better supply of essential elements in plant growth, such as K＋; （iii） a decrease in toxic ions such Na＋ and CI in aerial organs; and （iv） an additional synthesis of organic solutes and osmoprotectors like proline and proteins. All these results suggest that salicylic acid could be successfully used in alleviating depressive effects of salt on the productivity of the cultivated tomato.

Design Optimization for Generating a High Static Magnetic Field

引用

World Journal of Engineering and Technology 2023年第4期11卷 793-806页

This paper details the creation of a device capable of generating a powerful and consistent static magnetic field. This apparatus serves the purpose of quantifying the magnetostrictive strain found in materials like annealed cobalt ferrite and Terfenol-D, specifically those shaped as cylindrical rods. In our investigation, the use of static magnetic fields proves most advantageous. This choice is made to mitigate the generation of eddy currents, which would inevitably occur if the magnetic field intensity were varied. The fundamental idea behind this design involves employing a C-shaped iron core constructed from low-carbon mild steel. On this core, three coils are mounted, each capable of producing one-third of the required 9000 Oersted (Oe) magnetic field strength. The test specimen is situated within the “jaws” of the C-shaped core, thus completing the magnetic circuit. To manage the heat generated by each coil, a cooling system consisting of copper tubes is employed. These tubes facilitate the flow of air to dissipate the heat. To model and predict the magnetic field strength produced by the coils, finite element analysis (FEMM) software is utilized, and the results align closely with the anticipated outcomes. This design effectively generates a robust and unchanging magnetic field measuring a stable 9000 Oe in total. Consequently, this equipment finds utility in characterizing the magnetic properties of specific materials.
