Intelligent Load Management Scheme for a Residential Community in Smart Grids Network Using Fair Emergency Demand Response Programs  [PDF]
Muhammad Ali, Z.A. Zaidi, Qamar Zia, Kamal Haider, Amjad Ullah, Muhammad Asif
Energy and Power Engineering (EPE) , 2012, DOI: 10.4236/epe.2012.45044
Abstract: In the framework of liberalized deregulated electricity market, dynamic competitive environment exists between wholesale and retail dealers for energy supplying and management. Smart Grids topology in form of energy management has forced power supplying agencies to become globally competitive. Demand Response (DR) Programs in context with smart energy network have influenced prosumers and consumers towards it. In this paper Fair Emergency Demand Response Program (FEDRP) is integrated for managing the loads intelligently by using the platform of Smart Grids for Residential Setup. The paper also provides detailed modelling and analysis of respective demands of residential consumers in relation with economic load model for FEDRP. Due to increased customer’s partaking in this program the load on the utility is reduced and managed intelligently during emergency hours by providing fair and attractive incentives to residential clients, thus shifting peak load to off peak hours. The numerical and graphical results are matched for intelligent load management scenario.
Novel method for determination of sodium in foods by thermometric endpoint titrimetry (TET)  [PDF]
Thomas Smith, Christian Haider
Journal of Agricultural Chemistry and Environment (JACEN) , 2014, DOI: 10.4236/jacen.2014.31B005
Abstract:

A novel yet simple, rapid and robust thermometric endpoint titration (TET) method for the determination of sodium in various foodstuffs is described. Sodium reacts exothermically with aluminium in the presence of an excess of potassium and fluoride ions to form NaK2AlF6 (“elpasolite”). This reaction forms the basis of a ro- bust, reliable analytical procedure suitable for routine process control. The reaction of calcium under similar conditions (to form KCaAlF6) suggests that potentially, calcium may interfere in the determination of sodium in some foodstuffs. Results of an investigation suggest that at molar ratios [Ca]/[Na] < 0.85, an error of <1% of the measured value of sodium is incurred.

Preliminary Magnetic Susceptibility Results from the Northwestern Part of Madinah, Saudi Arabia: Environmental Degradation of Wadi Aqiq  [PDF]
Haider Zaman, Adnan Aqeel
Open Journal of Geology (OJG) , 2018, DOI: 10.4236/ojg.2018.84026
Abstract: Recent advances in environmental magnetism have led to new applications in understanding soil pollutions from anthropogenic sources. The utility of environmental magnetic techniques varies widely depending on biological, chemical and physical processes that create and transform soils and sediments. Researchers in some European and Asian countries have successfully studied heavy metals in top soils using magnetic susceptibility technique. Accelerated urbanization in the past two decades has significantly altered the environmental landscape of Madinah. A famous wadi Aqiq in the heart of Madinah, an important conduit for groundwater recharge, is one of the most affected. This study thus focuses on magnetic susceptibility application as environmental magnetic technique to map heavy metal concentrations in top soils along wadi Aqiq, northwestern part of Madinah. Higher values of magnetic susceptibility from soil cover than those from parent igneous rocks indicate anthropogenic origin metallic contamination in the study area. The trucks/tankers parking area reveal highest values of magnetic susceptibility. The areas close to heavy vehicular traffic along two major roads also indicate higher magnetic susceptibilities because of enhanced metallic contaminations. The areas covered by residential and commercial buildings reveal medium level of magnetic susceptibilities. The left over asphalted materials at various places in the area is another source of high magnetic susceptibilities. Widely distributed metallic objects in the area, such as hangers, cans, and construction materials also contribute to enhanced soil contamination as evident from high magnetic susceptibilities.
Dressing after Dressing: Sadra’s Interpretation of Change  [PDF]
Muhammad Kamal
Open Journal of Philosophy (OJPP) , 2013, DOI: 10.4236/ojpp.2013.31009
Abstract:

This paper deals with the doctrine of transubstantial change advocated by Mulla Sadra in which substances as well as accidents are thought to be in constant and gradual change. Against Aristotle’s doctrine of accidental change, Mulla Sadra argues that no stable ground can bring about change and since substance is renewable it cannot carry identity of a changing existent. Here we investigate whether identity is possible or not. If it is possible then what becomes a ground for establishing identity of changing substances.

Aliskiren Augments the Activities of Anti-Oxidant Enzymes in Liver Homogenates of DOCA Salt-Induced Hypertensive Rats  [PDF]
Sahar Kamal
Advances in Enzyme Research (AER) , 2014, DOI: 10.4236/aer.2014.22010
Abstract: Hypertension is a serious problem that is recently thought to be associated with damaging effects on target organs partially via oxidative stress. On the other hand, there is accumulating literature describing some sort of therapeutic interaction between antioxidant enzymes in vital organs and hypertension. Therefore, the aim of this study is to investigate the possible effect of a direct renin inhibitor, aliskiren, used in treatment of hypertension via renin-angiotensin-aldosterone system (RAAS), on selected anti-oxidant enzymes in hepatic homogenates in DOCA salt-induced hypertesnive albino rats. Thirty male wister albino rats were assigned randomly into 3 groups (n = 10/ group). Group 1 received no treatement and serves as control. Group 2 received 0.5% carboxymethylcellulose sodium ip as a solvent of aliskiren, as a direct renin inhibitor (DRI). Group 3 received aliskiren 100 mg/kg/day ip for 4 weeks through gastric tube. Systolic blood pressure (SBP) was measured every week and its mean was recorded at the end of the study. Superoxide dismutase (SOD) enzyme in RBCs lysates, activities of catalase (CAT) and glutathione peroxidase enzymes and thiobarbituric acid reactive substance (TBARS), as a marker of lipid peroxidation, in hepatic homogenates were measured at the end of the study. DRI produced a marked reduction in mean SBP of hypertensive rats. It also significantly (p < 0.05) increased the activities of measured anti-oxidant enzymes while it significantly (p < 0.05) reduced TBARS in liver homogenates. These results indicated that renin possesses an oxidative effect in the liver in hypertensive rats. Aliskiren, in addition to its powerful anti-hypertensive effect, it could induce a great anti-oxidant effect in liver homogenates of DOCA salt-hypertensive rats.
Individual Essences in Avicenna’s Metaphysics  [PDF]
Muhammad Kamal
Open Journal of Philosophy (OJPP) , 2014, DOI: 10.4236/ojpp.2014.41004
Abstract:

Central to Aristotle’s metaphysics is the question of individuality. The individuality of each substance is explained in relation to matter because the form is universal. Avicenna, as one of the Aristotelian Neoplatonist philosophers, is not content with this explanation and proposes to establish individuality on other grounds. In this paper, I argue that in his perspective it is not the matter which determines individuality but rather the principle of existence.

 

Metal-Like Gravity and Its Cosmological Applications  [PDF]
Kamal Barghout
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.518211
Abstract: Modification to Newton gravitational interaction is presented. It provides an understanding of a novel universal gravitational field of particle origin that defines alternative attributes to elementary constituents of matter particles and the gravitational interactions between them. It investigates gravitational relationship between two types of mass. The model assigns Coulombic gravitational interaction to DM particles and baryons by attributing self-antigravity to both normal matter and dark matter (DM). It defines the interaction as like particles repel while unlike particles attract. Metal-like force is proposed where same type mass (baryons) are gravitationally attracted to each other when a sea of DM particles are attracted to them and glue them together analogous to a metal bond. At close range, other dominant forces take place such as electromagnetic force. In light of this model, intergalactic self-repulsive DM particles are proposed to result in accelerating expansion of the universe. The model produces flat rotational curves for spiral galaxies and provides a physical explanation to MOND theory.
MLG vs. MOND  [PDF]
Kamal Barghout
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.64053
Abstract: In a recently published paper Metal-Like Gravity (MLG) and Its Cosmological Applications [1], it was determined that a new modification of Newtonian gravity could explain many of the cosmological mysteries such as the nature of dark matter and dark energy. The theory provided a gravitational physical system and explained the flatness of the galactic rotational curves (RC). A RC fit that was identical to MOND’s RC fit for spiral galaxies was generated with α as a fitting parameter determined as equal to 1.345. In this paper I am elaborating more on the theory’s cosmological extrapolation of MOND’s critical acceleration a0. This is done by further assessing the gravitational interaction between the galactic baryonic mass and the halo-DM mass in the star-galaxy overlapping volume estimated in MLG framework interpreting a0 as only a factor induced from the reduction of the galactic luminous mass. It is asserted that MOND and MLG dynamic equations are equivalent with MOND’s form, only expressing the equation with an intermediate solution by equating the magnitudes of δ (a parameter that defines a scaled surface galactic DM-density perpendicular to the galactic radial direction in the galaxy-star halo overlapping volume) and G.
Avicenna’s Necessary Being  [PDF]
Muhammad Kamal
Open Journal of Philosophy (OJPP) , 2016, DOI: 10.4236/ojpp.2016.62018
Abstract: This article examines the distinctive characteristics of Avicenna’s doctrine of the Necessary Being, arguing that Avicenna developed his doctrine under the influence of Aristotle’s metaphysical thinking, but, unlike Aristotle he does not proceed from the distinction between form and matter. Instead, Avicenna has established his doctrine on essence-existence dichotomy. The article also investigates Avicenna’s view on God’s knowledge of particulars in light of his doctrine of the Necessary Being. The article begins by discussing Aristotle’s analysis of the meaning of the prime cause and its simplicity. It will then examine the simplicity of the Necessary Being in light of Aristotle’s metaphysics.
Ibn ‘Arabi and Spinoza on God and the World  [PDF]
Muhammad Kamal
Open Journal of Philosophy (OJPP) , 2017, DOI: 10.4236/ojpp.2017.74021
Abstract: This paper is a comparative analysis of Ibn ‘Arabi’s and Spinoza’s interpretation of God’s existence and its relation with the world. The focus will be on the ontology of these two thinkers from different intellectual traditions, elucidating their tripartite system in order to find out whether the reality of the world in its relationship to God is denied or affirmed. To vindicate the similarities between the ontological views of Ibn ‘Arabi and Spinoza this paper argues in light of God’s simplicity and causality that the existence of the world can be understood by denying and affirming its identity with God.
