A theoretical study has been done to investigate the significant enhancement of the photorefractive and photovoltaic effects of a new co-doped potassium niobate crystal (KNbO3: Fe: Ag) as compared to the result obtained for singly doped potassium niobate crystals. The co-doped Ag impurity enters the K site, rather than the typical Nb site, thus changing the local field in the lattice. It is believed that Fe perturbed by the Ag in the K site is responsible for an enhancement of the linear absorption and photocurrent, as well as for the probable increase in the effective trap density. An enhanced trap density is likely the cause of the increased photorefractive counter-propagating two-beam coupling efficiency. http://www.scirj.org/jul-2014-paper.php?rp=P0714157
Accountability in the control and management of public funds is one of the most sensitive aspects of the activities of government in all democracies. Hence, the 2007 the regulation enacted by the Republic of Indonesia contains provisions relating to control over public funds. However, the required level of accountability in public expenditure has not been achieved by some churches in Bali. The situation has remained worrisome even though the region does not lack in appropriate laws and regulation required to bring rationality into the system. Though there have been some bold steps and initiatives in the recent past by the government through strengthening existing institutions and creating new ones with responsibility for fraud prevention and other controls, the issue of weak accounting infrastructure has not been addressed. http://www.scirj.org/jul-2014-paper.php?rp=P0714152
Referral of patients to specialists and hospitals is an essential and inevitable aspect of primary health care. Maintain good communication is essential during the process in order to provide quality care without delays and unnecessary expenses. In Sri Lanka referral letter from a general practitioner (GP) is not essential to get admitted to a hospital or to consult a specialist and there is no registered population for a particular practitioner. This study was conducted to look at the views of general practitioners on referral communications. http://www.scirj.org/jun-2014-paper.php?rp=P0614149
The purpose of this study was to identify the factors contribute to ability caders accepted family planning in Low Parity Young Fertile Married Couple (LP YFMC). The design of this study was quantitative study with crossectional approach. This study was conducted at subdistricts Tambaksari and Semampir, Surabaya. The unit of analysis was family planning caders. Sample size was calculated proportionally and complying the sample size requirement, which was 60 samples http://www.scirj.org/jun-2014-paper.php?rp=P0614147
Doctors often assume that patients have basic knowledge of the body and its functioning. Patients’ knowledge may vary and could depend on number of factors. Misunderstandings in consultation could lead to patient dissatisfaction, unsatisfactory compliance and outcome. This study explored patients’ knowledge on location of organs. http://www.scirj.org/jun-2014-paper.php?rp=P0614148
This work was aimed at providing preliminary findings that unraveled the promising potential of X. americana for the management of Mycobacterium bovis. The study tried to assess the anti-mycobacterial activity of Ximenia americana using the leave extract after extracting with methanol for 48 hours and the extract subjected to serial solvent partitioning with hexane, chloroform and n-butanol. The various solvent fractions obtained from the partitioning were screened against Mycobacterium bovis and the result showed hexane, chloroform and n-butanol extracts to inhibit the growth of the bacteria with a minimum concentration (MIC) of 3200 µg/ml, 1800 µg/ml and 3500 µg/ml respectively. The activity of the chloroform extract was found to be higher than the hexane and n-butanol as such Bio-assay guided fractionation of the chloroform extract was further carried out using column chromatography and nine fractions were obtained. http://www.scirj.org/jun-2014-paper.php?rp=P0614144
Poultry production is a growing business sector worldwide, owing partly to its profitability and partly to being a ready and affordable source of protein requirement for man. A major problem facing poultry is disease, a state of ill health that could lead to death or poor level of performance of the affected poultry. The scope of this paper, therefore, covers the control and management of disease outbreak in poultry, focusing on the tentative diagnosis of an implicated disease through software application. The software developed, called Pathfinder, using Java programming language and MySQL, provides users, e.g. veterinarians and animal health technologists, an easier, quicker and more precise procedure for tentative diagnosis of poultry diseases.
This paper aims at interrogating the apparent dearth of ideology, particularly at the level of party politics, in Nigeria. It is contended however that, in realty, beneath this seeming dearth of ideology there is a convergence of commitment to some normative values and ideas by the political class which is distinctively neoliberal.This ideological predilection underpins the posture of the state as it does the manifestoes of the ruling and opposition parties. Against this backdrop, this paper engaged with the nexus between ideology, party politics and Nigeria’s politico-economy and holds that it is of critical imperative for the managers of state to be aware of and factor in the contradictions which this neoliberal ideological posture entails for the quest for national development.
The present paper focuses on effectiveness of the Higher Education System in the research domain of Sri Lanka as a unit of analysis. The aim of this research paper is to explain and elaborate the system of Higher Education prevailed in the Island since its inception and how the colonial objectives have transformed to social demands and economic changes prevailed in Sri Lanka and how far Sri Lanka has succeeded to modernize the Higher Education policy with the aim of enhancing the efficiency of the system to fit into the globalized trend. Finally the research will serve as a base for the policy makers for possible changes at the appropriate stages to be addressed or adopted.
In this paper we presents the bit error rate (BER) performance of the Cyclic Redundancy Check (CRC) coded Long Term Evolution (LTE) system under various digital modulations (BPSK, QPSK and 16PSK) over an additative white gaussian noise (AWGN) and other multi path fading (Raleigh and Rician) channels. It is apparent from the Matlab based simulation study that the proposed LTE system outperforms with BPSK as compared to other modulation schemes under AWGN noisy and Rayleigh and Rician fading channels. The transmitted data is found to have retrieved effectively at the receiver end under the implementation of CRC coding/decoding algorithm. It has been also predictable that the performance of the CRC-based LTE system degrades with the increase of noise power. http://www.scirj.org/rp/items/show/78
