Jaffry Zakaria, Zulakbal Abd Karim, Azali Rahmat, Sanmuga Nathan K. Jeganathan
Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1104011
Abstract:
This article aims to look upon the guidelines regarding the preparation of facilities and risk management of training activities for disable athlete. The facilities and appropriate training activities are one of the vital entities to prepare them towards better performance. Suitable facilities for every group will give advantages toward any service provider; thus their facilities will always be users’ choice. However, special facilities for this group are also needed to be taken into consideration to ensure equality for them. This group needs to be given attention and helps to ensure that their success in sports area can be highlighted and they may experience what was felt by other normal athletes, indirectly. But, the facilities and non-user-friendly risk management of the training practices result to the limitation of their mobility and potential in our country’s sports arena. Lack of scientific material regarding disabled athletes in risk management field also contributes to the reason why authors wish to share discussion to give precise and useful information for readers.

International Research Journal of Pharmacy , 2011,
Abstract: A stability-indicating HPLC method development and validation for the determination of Lacidipine in tablets. The determination was done for an active pharmaceutical ingredient, its pharmaceutical dosage form in the presence of degradation products impurities. The drug was subjected to stress conditions of hydrolysis (acid and base), oxidation, photolysis and thermal degradation as per International Conference on Harmonization (ICH) prescribed stress conditions to show the stability-indicating method. Degradation was observed during acid, base hydrolysis, thermal, peroxide and light stressed sample and degradant was identified by LC–MS, FTIR and 1H/13C NMR spectral analysis. The generated samples were used for forced degradation studies. In the developed HPLC method, the resolution between Lacidipine and, its related impurities (namely impurity-A, impurity-B, impurity-C, impurity-LC1 and impurity-LC2) was found. The chromatographic separation was achieved on a phenomenex Luna C18, 250 mm × 4.6 mm, 5 μm column. The LC method employed an isocratic elution, and the detection wavelength was set at 240 nm. The stress samples were assayed against a qualified reference standard and the mass balance was found to be close to 99.6 %. The developed RP-LC method was validated with respect to linearity, accuracy, precision and robustness.

Indian Journal of Materials Science , 2014, DOI: 10.1155/2014/536123
Abstract: TiO2 plays a significant role in many applications including solar cell. Consecutively to absorb the low-energy radiation, it is very much essential to tune the optical property of TiO2. We fabricated CeO2-ZnO-TiO2 semiconductor composites by sol-gel method and achieved the absorption of lower energy radiation. The prepared composites were characterized by TG-DTA, UV-DRS, XRD, AFM, TEM and FESEM techniques. The particle and crystalline size of the composites was calculated using FESEM and XRD techniques, respectively. The photocatalytic activity of the synthesized composite for the degradation of Rhodamine B (RhB) under visible light irradiation was investigated. The photocatalytic degradation of RhB under various experimental conditions such as amount of catalyst, initial dye concentration and H2O2 amount was also demonstrated and the rate constant was calculated using L-H model. 1. Introduction Semiconductor metal oxide plays an important role in heterogeneous catalysis, electrochemistry, gas sensors, and other applications. Recently titanium dioxide (TiO2) received a lot of attention due to its chemical stability, nontoxicity, and low cost. TiO2 is used as a gas sensor, antireflection coating in many thin-film optical devices, biomaterials, catalyst/support/additive in catalytic reactions [1–4] and as a good photocatalyst [5, 6]. It is well known that TiO2 absorbs wavelength shorter than 385?nm due to its band gap of about 3.2?eV. Since very narrow range of such high energy radiation is available in solar light spectrum, it is very difficult to convert solar energy to chemical oxidizing power. So, it is very urgent to tune the optical property of TiO2 for utilizing a large fraction of the solar spectrum to realize the indoor applications of this material. For this reason, modification of TiO2 is done by various strategies like coupling with a narrow band gap semiconductor, metal ion/nonmetal ion doping, codoping with two or more foreign ions, surface sensitization by organic dyes or metal complexes, surface fluorination, and noble metal deposition. Nanocomposites such as TiO2-SiO2 [7, 8], ZnO-CdS [9], TiO2-WO3 [10, 11], TiO2-CeO2 [12], TiO2-Fe2O3 [13], In2O3-TiO2 [14], TiO2-CdSe [15], TiO2-CdS [16], and TiO2-ZnO [17] have been considered as effective photocatalysts. Cerium oxide (CeO2) is the most reactive rare earth metal oxide that has broad range applications in various fields [18] and it is an additive in the automotive three-way catalysts [19]. The redox couple of Ce3+/Ce4+ and the high capacity to store oxygen of CeO2 have gained additional

American Journal of Analytical Chemistry (AJAC) , 2016, DOI: 10.4236/ajac.2016.74035
Abstract: A theoretical model for the non steady-state response of a pH-based potentiometric biosensor immobilizing organophosphorus hydrolase (OPH) is discussed. The model is based on a system of five coupled nonlinear reaction-diffusion equations under non steady-state conditions for enzyme reactions occurring in potentiometric biosensor that describes the concentration of substrate and hydrolysis products within the membrane. New approximate analytical expressions for the concentration of the substrate (organophosphorus pesticides (OPs)) and products are derived for all values of Thiele modulus and buffer concentration using new approach of homotopy perturbation method. The analytical results are also compared with numerical ones and a good agreement is obtained. The obtained results are valid for the whole solution domain.
Description of a new Lithoxus (Siluriformes: Loricariidae) from the Guayana Highlands with a discussion of Guiana Shield biogeography

Neotropical Ichthyology , 2008, DOI: 10.1590/S1679-62252008000300014
Abstract: lithoxus jantjae, new species, is described from above tencua falls in headwaters of the ventuari river, a white- to clearwater river flowing west from the maigualida and parima mountains in the guayana highlands of southern venezuela. lithoxus jantjae represents a nearly 600 km westward range expansion for a genus historically known only from guyana, suriname, french guiana, and brazil. lithoxus jantjae shares with other species of lithoxus a dorsoventrally depressed body and a large, papilose oral disk with small toothcups and few teeth. it can be distinguished from congeners by a unique combination of characters including 12 branched caudal-fin rays, medial premaxillary tooth cusps enlarged, and a convex posterior margin of the adipose-fin membrane. with the discovery of l. jantjae, lithoxus becomes the most recent example of a growing list of rheophilic loricariid genera with disjunct distributions on east and west sides of the guayana highlands. a biogeographic hypothesis relying on the existence of a proto-berbice river uniting the southern guayana highlands with rivers of the central guiana shield is advanced to partially explain the modern distribution of these species.
Circuit QED - Lecture Notes
Nathan K. Langford
Physics , 2013,
Abstract: The new and rapidly growing field of circuit QED offers extremely exciting prospects for learning about and exercising intimate control over quantum systems, providing flexible, engineerable design and strong nonlinearities and interactions in systems consisting of microwave radiation fields and fixed artificial "atoms". These notes aim to provide a non-expert introduction to the field of circuit QED, to give a basic appreciation of the promise and challenges of the field, along with a number of key concepts that will hopefully be useful for the reader who is new to the field and beginning to explore the research literature. They were written as a pedagogical text designed to complement a course delivered to third-year undergraduate students. After a introductory section which discusses why studying circuit QED might be worthwhile and interesting, I introduce the basic theory tools from quantum optics and quantum information which are needed to understand the key elements of circuit QED. I also provide a brief overview of superconductivity, focussing on the concepts which are most relevant to operation in the regimes of interest in circuit QED. I then describe the three main types of superconducting qubits, and finally give a basic introduction to decoherence and mixture and how they relate to quantum behaviour in electronic circuits.
