On the Component Analysis and Transformation of An Explicit Fifth – Stage Fourth – Order Runge – Kutta Methods

Research Article
Author(s): Agbeboh Goddy Ujagbe, Esekhaigbe Aigbedion Christopher
Journal: International Journal of Mathematical Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This work is designed to transform the fifth stage – fourth order explicit Runge-Kutta method with the aim of projecting a new method of implementing it through tree diagram analysis. Efforts will be made to represent the equations derived from the y derivatives and x,y derivatives separately on Butcher’s rooted trees. This is because the rooted trees and derived equations for the y derivatives and x,y derivatives are the same for the explicit fourth-stage fourth-order methods, hence, we are motivated to analyze the fifth-stage fourth-order method. This idea is also derivable from general graphs and combinatorics.

Research Article
Author(s): Christopher Mulanda Aura, Farida Hassan, Melckzedeck K. Osore, Safina Musa, George Morara, Jacqueline Uku
Journal: International Journal of Management and Sustainability

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This paper outlines an effective and comprehensive public-private partnership approach that has the potential to enhance natural resource management (NRM) and improve access to essential community services (CS). The paper is based on the institutional and resource-dependency theories on the management of Kenya Coastal Development Project (KCDP) community development fund (Known in Swahili as Hazina ya Maendeleo ya Pwani, HMP), financed by Kenya Government through a loan from the World Bank at the Kenya coast. The HMP fund targets CS and NRM sub projects implemented by communities in the six coastal counties. To ensure sustainability of HMP financed sub projects, the framework involved strategic planning, system design, finance usage, implementation, and connection of theory and practice based on research and interpretation. KCDP data on HMP financed community projects implemented since 2013-2015 was used in the evaluation of project performance. Counties with enhanced security, and improved socio-economic status benefit the most in the project. The coastal communities were more willing-to-contribute towards implementation of CS than NRM projects due to consumptive nature attached to the former in the short term. Gender parity in the HMP participation occurred, attracting more women than men. By careful designation of the project management framework, sustainable management of natural resources and access to most immediate needs, considered crucial by coastal residents are highly likely to be met.
Contribution/ Originality
 This study documents and discusses a comprehensive public-private partnership approach for resource mobilization and capacity building towards sustainable delivery of essential social and ecosystem services for improved wellbeing of the communities along the Kenya coast.

Abstract
Dengue fever is a fatal infection affecting the lives of the patients and this study was designed to further explore its pathological effects. A total of 200 consecutives of dengue viral infection were included in this prospective descriptive study conducted at the Department of Pathology, University of Veterinary and Animal Sciences, Lahore from October, 2009 to September, 2010. A special proforma was designed to collect all the relevant clinical information from each patient. All the strip positive cases of dengue virus were further confirmed by performing IgM capture ELISA and then analyzed for hepatic impairment through liver function tests including serum bilirubin, serum alkaline phosphatase, serum ALT and AST. The results were then gathered and analyzed. The already existing liver diseases like hepatitis A, B, C, E and inherited liver disorders were not included in the study. Total number of patients included in study with Dengue IgM +ve were 200. Out of 200 cases 130 were male and 70 were females. The patients were categorized into two classes according to severity of sign symptoms like puerperal rash on the body. The classes are dengue fever (DF) and dengue hemorrhagic fever (DHF). The total number of DF cases was 28.50% (57/200) and number of DHF cases was 71.50% (143/200). The patients of DHF group were found to have more liver derangement that is 90.20% (128/200) while the patients belonging to DF group were at a less risk for impairment of liver function that is 9.80% (15/200). The patients with dengue hemorrhagic fever are more prone to have liver enzyme derangement and it has a direct relation with the titer IgM in the body of patients infected with dengue virus. The liver enzyme which are found to be more raised are serum ALT and AST while serum alkaline phosphatase and serum bilirubin are not markedly raised.
Contribution/ Originality
This study contributes to the existing literature by exploring pathological effects of dengue fever in humans and relation with biochemical parameters. The logical analysis has primary contribution in its finding that dengue fever is more prevalent in males and serum liver enzyme level rises as IgM level raises.

Journal: Journal of Diagnostics

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The abnormalities of the kidney can be identified by ultrasound imaging. The kidney may have structural abnormalities like kidney swelling, or change in its position and appearance. Kidney abnormality may also arise due to the formation of stones, congenital anomalies, blockage of urine etc. For surgical operations it is very important to identify the exact and accurate location of stone in the kidney. The ultrasound images are of low contrast and contain speckle noise and could affect human body in some situations like pregnancy. This makes the detection of kidney abnormalities rather challenging task. Thus, microwave imaging could be a good alternative. A microstrip patch antenna scanning system allows to identify the exact and accurate location of stone in the kidney. A physical testing system will be developed in order to generate antenna response surfaces on material which could represent the human body. The serum is used in the experimental measurement because it has similar dielectric properties as human body.  In order to represent stone  presence in an homogenous medium, small calcium sto  ne bearings of different sizes embedded are used to simulate the abnormality. Compact microstrip patch antenna were designed and tested at different frequencies in ISM band : 2.26 GHz, 2.38 GHz, 2.5 GHz, and 2.62 GHz for the RF investigation imaging system in order to detect and localize stones in the kidney.

Abstract
The current study aimed to demonstrate the hepatoprotective effect of chamomile extract and its role in relieving the ultrathin structure changes in liver tissue caused by 2, 4-Dichlorophenoxy acetic acid (2, 4-D) using electron microscopy.This experiment was performed on 12 -14 weeks old male Wistar  rats divided into six groups (six animals each). The first group was kept as control. The second and third groups received orally accumulative doses of 75 and 150 mg/kg body weight (b.wt.), of 2, 4- D respectively. The forth group received orally Chamomile extract (500 mg/kg b.wt.) alone. The last two groups received Chamomile extract with either doses of 2, 4-D (75 or 150 mg/kg b.wt). At the end of the experimental period (4 weeks), the liver was dissected and examined by electron microscope. Histopathological examination of liver sections of rats administered 2, 4-D75 mg/kg showed differences in nuclear shapes and size, envelope and increase in heterochromatin masses. Adminstration of 2, 4-D150mg/kg showed pyknosis and changes inmitochondria, endoplasmic reticulum, Kupffer cells, increases in lysosomes and lipid droplets. Chamomile group showed the normal control ultra structure of the liver. In group treated with chamomile and 2, 4-D75,there was improvements in all degenerative changes induced by 2, 4-D75. Chamomile and 2, 4-D150 groupshowed partial improvement in both nucleus and the mitochondria. Chamomile reduces the oxidative damage induced by 2, 4-D due to its antioxidant properties. It is recommended that Chamomile extract can be taken to ameliorate hepatotoxicity.
Contribution/ Originality

Export to    BibTeX   |   EndNote   |   RIS

Abstract
In this communication, a new multi-antenna system based on two microstrip antennas is analyzed and proposed for LTE (Long Term Evolution) terminals. The multi-input multi-output (MIMO) antenna is printed on a FR4 substrate with size of 60×100×1.6 mm3. The proposed design, in its basic form, operates around 2.3 GHz, and provides a transmission coefficient of -19 dB. In order to improve the isolation between the two antenna ports, some rectangular and circular slots are inserted in the ground plane between the two antennas. With this modification, the mutual coupling of -59 dB was achieved, which are 40 dB improvements over the initial antenna. The simulated results are presented and discussed in term of reflection coefficients, transmission coefficients and radiation patterns.
Contribution/ Originality
This study presents a new antenna design, proposed for MIMO/LTE application. This proposed antenna provide a low mutual coupling (less than -59 dB) between the two ports which ensure a high isolation.

Abstract
In this paper, we study the ability of quantum networks to support both random and non-random data traffic single-photon quantum communications signals on a shared infrastructure. The effect of wave length on distance coverage with the quantum bit error rate (QBER) of a quantum key distribution (QKD) system is increasing. The results of random phase showed minimal distance coverage over non-random phase. For fluctuating amplitude of random show a change in system performance improved sending capabilities.  Hence, it is found that rare fluctuations should not degrade system performance significantly, but the data sending mode has a significant effect on channel integrity.
Contribution/ Originality
This study presents an original structure of generalized quantum key distribution suitable for wavelength division multiplexing (WDM) application.

Abstract
In the present study, a sol-gel dip-coating process was used to deposit almost stress free highly c-axis oriented nanostructured ZnO thin films on glass substrates. The effects of low silver doping concentration (Ag ? 1 at.%) on the structural, morphological and  optical properties of such films were investigated using different characterization techniques. X-ray diffraction (XRD) measurements have revealed that all the ?lms were single phase and had a hexagonal wurtzite structure. The grain size values were calculated and found to be about 24-29 nm. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) images have shown that film morphology and surface roughness were influenced by Ag doping concentration. Optical properties such as transmittance and optical bandgap energy (Eg) were examined using UV-Visible spectrophotometry. The results have indicated that all the prepared ?lms were highly transparent with average visible transmission values ranging from 80% to 86%. Moreover, it was found that the Ag contents leads to widening of the bandgap.
Contribution/ Originality
This study is one of very few studies which have investigated the preparation of low Ag-doped ZnO thin films by the sol-gel dip-coating technique. It was put into evidence that incorporation of low Ag concentrations (Ag ? 1 at.%) in ZnO can indeed improve its physical properties.

Journal: Animal Review

Export to    BibTeX   |   EndNote   |   RIS

Abstract
In today’s world, the biological sciences are mostly considered separate from the existing modern knowledge of various other fields of sciences and engineering; however, there are many properties of nature and known facts of biological sciences that can be proved in the other domains of science and technology as well. Correlation of the geometric and buoyant properties of the swimming animals with the hybrid buoyant aerial vehicles is an example of this hypothesis. In the present work, some experiments related to the geometric parameters of a California sea lion were carried out. It was found that the fineness ratio of this animal is of the same order as the optimum value of that for the condition of minimum drag and power required for the buoyant aerial vehicle. The role of multiple fins on the elongated bodies of shark is also discussed in its application for yaw stability as well as to shroud the antennas that are used in the aircraft for various communication systems.
Contribution/ Originality
The paper's primary contribution is to show that the hydrodynamic and a few geometric parameters of a California Sea Lion resemble to that of the well-known facts of buoyant and hybrid buoyant aerial vehicles.

Islamic architecture has a clear impact for systems and the relationships of Mathematical and  Geometrical proportions , which reflected in their buildings.  The research will deal with an important aspect that linked in two mains elements in the Congregational Mosques. The first is a house of prayer (Al-mousala) as the main and most importantly space in the mosque, and the second is a dome as structural and decorative element, who was significantly associated with Congregational Mosques later. This study is one of very few studies which have investigated the kind of the Mathematical& Geometrical proportions relationship, also the  spatial linking of these two elements with each other's.  Through the statistical analysis that links the relationship between their different dimensions and the positioning kind of the main dome on a house of prayer (Al-mousala). For this purpose the resaerch has been selected two sets of samples. The first models include a different regions of Islamic Congregational Mosques represent different patterns of Congregational Mosques as a sample of general Islamic architecture while the second comprises a number of Congregational Mosques in Mosul city, a representative of the local architecture.

Abstract
Cheese analogues are cheese-like products with varied compositions and functional properties which produced by partial or whole replacement of milk components, in particular milk fat, by non milk-based components. The purpose of this research was to evaluate the effect of replacement of milk fat in processed cheese with different formulations from olive, corn and sesame oils on some chemical and sensory properties. The results indicated that the peroxide values were not affected by the replacement of milk fat with vegetable oils significantly (P <0.05), while the free fatty acid content was slightly but significantly affected. These two values were significant (P <0.05) increased during the three months of storage. The cholesterol contents in the cheese samples with olive, sesame and corn oils were 86.9, 84%, and 83.1%, respectively lower than those of the whole milk cheese sample. The replacement of milk fat with vegetable oils did not affect the appearance, color and tenderness of the processed cheese samples. The replacement of milk fat with vegetable oil significantly (P <0.05) affected the flavor of the cheese analogue samples.
Contribution/ Originality
This study is one of the very few studies which have investigated the influence of the olive and sesame oil on the chemical and sensorial properties of processed cheese analogue.
