For controlling access to resources and data, the android platform offers contains a permission management system. However, recently several third-party applications are found abusing the android permission system. Such applications misuse the granted permissions without user knowledge. Some of the researchers have proposed permission managers which revoke the third-party application permissions to stop the misuse. Although such security applications allow users to revoke the app permissions, however, it is difficult for the users to differentiate between a genuine resource access and a malicious access. In this research work, a security application has been developedthat presents useful monitoring information to usersto help them in deciding on which applications should be restricted from using the phone resources and data. It monitors applications' and systems' activities (e.g., process importance, screen on/off information) and calculates the corresponding risk to notify user about the resource access. If further enables the user to revoke the granted permissions to an android application by considering such resource access reports.","PeriodicalId":21859,"journal":{"name":"Sindh University Research Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88912937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But later, other pharmaceutical companies get the rights to manufacture that drug. This increases the number of generic drugs available in the market and decreases the cost of therapy. But this decrease in cost of medicine does not mean poor quality. The objective of this research work was to identify that different generic products from local and multinational firms available in the market are comparable in quality to each other and innovator product and are pharmaceutically equivalent. A comparative qualitative research was carried out on innovator and genetic marketed formulations of atenolol tablets from multinational and local pharmaceutical industries. A total of five products were selected and different in-vitro tests were performed and compared against British Pharmacopoeia standards. All the marketed formulations of atenolol tablets were as per standards of British Pharmacopoeia and complied with the weight variation, dimension, hardness, friability, disintegration, dissolutions tests and assay. All the marketed formulations of atenolol tablets from innovator, multinational and local industry companies were pharmaceutical equivalent and can be used interchangeably.","PeriodicalId":21859,"journal":{"name":"Sindh University Research Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73788870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

New tools and technologies are being introduced to blend the technology within educational boundaries. The most important tools used to implement e-learning is the Learning Management System. There are large number of LMS available which are being used by the universities, colleges and schools. The selection of LMS is critical for the success of any e-learning system. This paper compares seven open source LMS i.e. Moodle, ATutor, Chamilo, Claroline, Efront, Docebo and Dokeos. The comparison is made on the basis of technical parameters and the communication tools. It has been made through practical installation and literature review. The results show that all the LMS are cross platform and based on PHP technology. All of the them have My Sql as the backend database. MOODLE and Atutor have additional support for Microsoft and Oracle. Both of them also provide the maximum communication sub tools. The specifications of e-learning standards were found to be more diversely described in different LMS. The comparison will help the administrators and educators to set a criterion according to their needs and adopt LMS which is suitable for their requirements.","PeriodicalId":21859,"journal":{"name":"Sindh University Research Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86675542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Concentrations of these elements were assessed in 55 fish samples of different size, randomly collected in January, 2015, from a private fish farm by ICP-OES after wet digestion method. Results of the study showed that analyzed elements were found within normal ranges. Ca, Cu, Fe, K, Mn, Na and Zn had highly significant relationships with fish size. Cd, Pb, Cu, K, Mn, Ni, Na, increased isometrically while Cr, Co, Zn, had negative allometric relationship and Fe and Ca showed positive allometric relationship with rise in weight of C. idella. Moreover, Ni, Mn, Pb and Cd represented isometric increase whereas Na, K, Zn, Fe and Ca had positive allometry; and Co, Cu, Cr had negative allometry with increase in total length of the fish. Most of inter-elemental relationships showed.

Reuse of Greywater is a hopeful alternative water source for non-potable uses, which could be exploited on a continuous basis and treated. Getting average removal% of Total Suspended Solids from greywater through Rotating Biological Contactor following experiment was conducted to evaluate the significance Hydraulic Retention Time with numbers of discs. Consequences reveal that linear as well as quadratic estimate of HRT and number of discs have are highly significant effect as their corresponding p-values are even less than 0.01.By using coefficients of the table the regression equation is Removal = Removal% = -26.74 + 20.14 Time + 1.253 Disc, where the sample standard deviation is 4.82. Lack of fit of the equation is insignificant i.e. 0.155, which implies that the regression equation is fit for prediction. The probability plot of the residuals is roughly straight which demonstrate that errors distributions are around normal. Furthermore, Residual plot shows the linearity assumption appear to be met with constant standard deviations. Histogram of Residuals make obvious normality assumptions as the plot resembles an example of a sample from a normal distribution centered at zero and normally and independently distributed NID (0, σ2) assumptions on errors are accomplished as standardized residuals are approximately normal with mean zero and unit variance.","PeriodicalId":21859,"journal":{"name":"Sindh University Research Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84526579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
