Computer Science , 2009,
Abstract: Secure access of communication networks has become an increasingly important area of consideration for the communication service providers of present day. Broadband Wireless Access (BWA) networks are proving to be an efficient and cost effective solution for the provisioning of high rate wireless traffic links in static and mobile domains. The secure access of these networks is necessary to ensure their superior operation and revenue efficacy. Although authentication process is a key to secure access in BWA networks, the breaches present in them limit the networks performance. In this paper, the vulnerabilities in the authentication frameworks of BWA networks have been unveiled. Moreover, this paper also describes the limitations of these protocols and of the solutions proposed to them due to the involved computational complexities and overheads. The possible attacks on privacy and performance of BWA networks have been discussed and explained in detail.

Zaheer Khan, Javed Ijaz Hussain, Sunil Kumar, Athar Adil Hashmi, Maqsood Ahmad Malik
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2011, DOI: 10.4236/jbnb.2011.24048
Abstract: Colloidal silver nanoparticles were prepared by reducing silver nitrate with oxalic acid in presence of cetyltrimethylammonium bromide (CTAB). The synthesized silver particles show an intense surface plasmon band in the visible region. The work reported in this paper describes the effect of concentration of various additives (NaCl, NaBr, NaNO3, Na2SO4 and NaH2PO4) and ammonia on the growth and stability of Ag-nanoparticles. In all the cases the rate decreases as the [electrolytes] or [ammonia] increases. The nature, polarizability and coordinating ability of the anions play vital roles for nucleus formation and the growth process, which subsequently form different size particles. Transmission electron microscopy, selected areas electron diffraction, and UV-visible spectroscopy have been employed to characterize Ag-nanoparticles. The effect of the following variables on the particle size and size distribution was investigated: the [oxalic acid], [CTAB] and [Ag+].The nanoparticles are stable in NaNO3 and NaH2PO4 solutions; but NaCl, NaBr and Na2SO4 causes their aggregation.

International Journal of Business and Management , 2011, DOI: 10.5539/ijbm.v6n7p287
Abstract: The present study was conducted to analyze the potential of SMEs in economy of Pakistan. Data were collected from 300 SMEs units by using Simple random technique. A structural questionnaire was developed to get the response from different SMEs units in Pakistan. Data were analyze by using SPSS-17.0 statistical software. It was revealed that SMEs in Rural Sindh has 45% contribution it can be increase by given facilities of marketing of those products. Moreover, SME exports are concentrated in labor-intensive sub-sectors where low wages are important to enhance the comparative competitive position of foreign markets and as well as SMEs do not necessarily export their products directly but through trade networks. The response rate was 90 percent only three units were sick units from last couple of years. It was further revealed that that potential contribution of SMEs to the sustainable growth of the Pakistan is large. Steps should be taken to ensure that more small firms are able to take advantage of government services. This may improve survival rates and stimulate development in lagging areas.

RAHEEL IRFAN
The Professional Medical Journal , 2002,
Abstract: T he Norplant is a long term sub-dermal implantable contraceptive devise consisting of six capsule each containing36mg of Levonorgestel (Progestrone ). It is implanted on the inner surface of the arm of the women for the period of fiveyears , and is slowly released from the Norplant capsule into women’s blood stream and acts as a contraceptive.OBJECTIVES: The aim of the study was to find out the effect of Norplant on the weight of the uterus of the femalealbino rat on gross examination. SETTING: The study was conducted in BMSI, JPMC Karachi over a period of65days. MATERIAL & METHODS: In the present study, the total number of 60 adult female albino rats wereselected, divided into 6 groups A,B,C,D,E and F. Each group except A was comprising of 6 animals. Group A, acted asan age matched control, A was subdivided into A1, A2, A3,A4 &A5. all comprising of six animals to act as age matchedcontrol for group B, C, D, E and F. All the animals in the respective groups received subdermal insertion of single rodof Norplant.The animals were sacrificed at the interval of 13 days and tissue (uterus) was dissected out under asepticconditions and their weight was done on sartorius balance. RESULTS AND OBSERVATIONS: The statisticalanalysis of comparison between different groups were carried out by applying student’s T test.The weight of the Uterusrevealed a highly significant increase with the length of the treatment. CONCLUSION: The conclusion drawn fromthis study is that the Norplant on one hand is no doubt acting as a contraceptive but on the other hand, leading to adverseeffects such as increase in weight of the tissue(Uterus)due to fibrosis and distortion and the structure of the uterus. whichmay lead to evil ailment as cancer.

Journal of Power and Energy Engineering (JPEE) , 2014, DOI: 10.4236/jpee.2014.24050
Abstract: Smart grid design and structures are somehow depending on the way of designing and operating Microgrids. In this research a unique design of microgrid is proposed as in medium tension isolated power distribution system contains diesel generation unit and photovoltaic generation. Storage system is a part of the control strategy to reduce the diesel usage and to maintain the balance between generation and demand which might be disturbed due to the presence of PV system. Fuzzy logic control scheme has been chosen compared with conventional controller to be the main controller for both the diesel unit and storage system. Promising result has been found by digital simulation using Matlab Simulink proving the possibility of reducing the dependency on fossil fueled generators and increase the utilization of renewable energy.

THE INTERPRETATION OF THE AMENDED RAF ACT 56 OF 1996 AND THE REGULATIONS THERETO BY THE COURTS WITH REGARD TO “SERIOUS INJURY” CLAIMS
Loma Steynberg,Raheel Ahmed
Potchefstroom Electronic Law Journal/Potchefstroomse Elektroniese Regsblad , 2012,
Abstract: The RAF Amendment Act 19 of 2005 came into effect on 1 August 2008 and sections 17(1) and 17(1A) introduced the concept of “serious injury”. This entails that a third-party claimant who wishes to claim compensation for non-patrimonial loss suffered after a motor-vehicle accident has to prove that his or her injury is “serious”. If the claimant’s injury is not considered “serious” no compensation will be awarded for the non-patrimonial loss suffered and, furthermore, the claimant will also not be entitled to claim any compensation from the wrongdoer in terms of common law (s 21 of the RAF Act). In a sequence of unreported cases the courts have provided guidelines on the procedure to be followed in serious-injury claims. Firstly, a claimant must submit himself or herself to an assessment by a medical practitioner registered under the Health Professions Act. Secondly, the medical practitioner must assess if the injuries sustained by the claimant fall within the list of “non-serious injuries”, and if so, compensation for non-patrimonial loss will not be awarded. If the injury is not on the list of non-serious injuries, the medical practitioner may assess the injuries and if they result in 30 per cent or more of whole-person impairment (“WPI”) compensation for non-patrimonial loss may be awarded. If the evaluation is that the 30 per cent of WPI cannot be reached, non-patrimonial loss may still be claimed if the injuries fall within the “narrative test”, namely (a) resulting in a serious long-term impairment or loss of a body function; (b) constituting permanent serious disfigurement; (c) resulting in severe long-term mental or severe long-term behavioural disturbance or disorder; or (d) resulting in the loss of a foetus. A plaintiff may use either of the two tests to establish serious injury and in such a manner qualify for compensation for non-patrimonial loss. A medical practitioner must complete and submit a serious-injury assessment report on the RAF 4. If the RAF is not satisfied that the injury has been correctly assessed they must (a) reject the serious-injury assessment report within 60 days and furnish reasons for the rejection; or (b) direct that the third party submit himself or herself, at the cost of the Fund, to a further assessment. Thereafter the RAF must either accept the further assessment or dispute the further assessment within 90 days. An Appeal Tribunal, consisting of three independent medical practitioners, has been created to hear these disputes.
