There has been a significant increase in the use of Android platform in the last decades mainly because of the features that it offers, i.e., open-source architecture, a wide range of Application Programming Interface (API). 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.
在过去的几十年里,Android平台的使用有了显著的增长,主要是因为它提供的特性,即开源架构,广泛的应用程序编程接口(API)。为了控制对资源和数据的访问,android平台提供了一个权限管理系统。然而,最近一些第三方应用程序被发现滥用android权限系统。这些应用程序在用户不知情的情况下滥用授予的权限。一些研究人员提出了权限管理器,可以撤销第三方应用程序的权限,以防止滥用。虽然这些安全应用程序允许用户撤销应用程序的权限,但是用户很难区分真正的资源访问和恶意访问。在这项研究工作中,已经开发了一个安全应用程序,它向用户提供有用的监控信息,以帮助他们决定哪些应用程序应该被限制使用电话资源和数据。它监视应用程序和系统的活动(例如,进程重要性,屏幕开/关信息),并计算相应的风险,通知用户有关资源访问。如果进一步允许用户通过考虑这些资源访问报告来撤销授予android应用程序的权限。

Fungal genome have highest number of the ATP binding cassette (ABC) superfamily PDR (Pleotropic drug resistance) sub divided into MDR (multi drug resistance) and MFS (major facilitator family). The major conserved domain of the super family comprised of various alpha helix proteins in form of ATP binding cassettes as transmembrane. Another conserved (NTP) nucleotide binding domain contained of conserved amino acids is more crucial domain of super family. ABC proteins are majorly involved in transport across cytoplasm and plasma membrane for the number of substrates as proteins, amino acids, ions and drugs. According to the recent studies yeast and Neurosporacrassahave highest number of orthologs and is the best model to uncover the underlying phenomena of drug resistance for the better understanding. There is dearth of study on the existence of drug transport proteins in pathogenic fungi. Study have focused on the emergence of CDR, MDR and MRS family major drug resistant transport proteins in various fungal groups.
真菌基因组中含有数量最多的ATP结合盒(ABC)超家族PDR(多效性耐药),又分为MDR(多药耐药)和MFS(主要促进剂家族)。超级家族的主要保守结构域由多种α -螺旋蛋白组成,以ATP结合盒的形式跨膜。另一个包含保守氨基酸的保守核苷酸结合域是超家族中更为重要的结构域。ABC蛋白主要参与蛋白质、氨基酸、离子和药物等底物在细胞质和质膜上的转运。根据最近的研究,酵母和神经孢子虫具有最多的同源物,是揭示耐药性潜在现象的最佳模型,以便更好地理解。目前对病原菌中药物转运蛋白的存在缺乏研究。研究重点是CDR、MDR和MRS家族主要耐药转运蛋白在各种真菌类群中的出现。

The new drug development process is very expensive, so initially when a new drug comes in the market the innovator pharmaceutical company gets the sole rights to manufacture the drug for specific time. 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.
新药开发过程非常昂贵,所以一开始当一种新药进入市场时,创新制药公司获得了在特定时间内生产这种药物的独家权利。但后来,其他制药公司获得了生产这种药物的权利。这增加了市场上可获得的仿制药数量,并降低了治疗成本。但是药品成本的下降并不意味着质量差。这项研究工作的目的是确定市场上本地和跨国公司提供的不同非专利产品在质量上彼此相当,创新产品在药学上是等效的。对跨国和本地制药业的阿替洛尔片的创新配方和遗传配方进行了比较定性研究。总共选择了五种产品,并进行了不同的体外试验,并与英国药典标准进行了比较。所售阿替洛尔片的处方均按英国药典标准执行,并符合重量变异、尺寸、硬度、脆碎度、崩解度、溶出度试验和含量测定。创新者、跨国公司和当地工业公司生产的所有阿替洛尔片剂的市场配方都是等效的,可以互换使用。

The use of e-learning is increasing in the educational sector. 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.

The main idea of this research is to figure out how we can create a mesh network in Android based cell phone keeping in mind the end goal to exploit the advantages of this sort of networks. Mesh networks has some extraordinary attributes that could enhance the client experience or even save lives in some extreme circumstances. In some situation where the density of individuals collapse the regular network, football stadiums or huge exhibits, or when some enormous disaster happens, tornados, tidal waves, tremors that bring down the network, mesh networks would permit us to make a few applications that allows the general population to communicate with people that is close to them, or to give an evacuation path from that specific zone.

Basic aim of this research was to determine levels of some metals (Ca, Cd, Cr, Co, Cu, Fe, K, Mn, Ni, Na, Pb Zn) and their relationships to body size and condition factor in the whole body of Ctenopharyngodon idella (Grass carp). 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. Multiple regressions analyses showed positive correlation for Fe, Cu, Zn, Mn, Pb, Na, K, Ca and Ni had highly significant relations with total length and body weight.

Increased attention towards substitute water resources has become unavoidable, as the world’s freshwater supply becomes gradually scarcer. 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.
随着世界淡水供应逐渐减少,对替代水资源的更多关注已不可避免。灰水的再利用是一种有希望用于非饮用用途的替代水源,可以持续开发和处理。通过实验,得到了旋转生物接触器对灰水中总悬浮物的平均去除率%,以评价水力停留时间与圆盘数的关系。结果显示,HRT和椎间盘数目的线性和二次估计具有非常显著的影响,其对应的p值甚至小于0.01。利用表中的系数,得到回归方程为:Removal = Removal% = -26.74 + 20.14 Time + 1.253 Disc,其中样本标准差为4.82。方程的拟合缺失不显著,即0.155,这意味着回归方程适合预测。残差的概率图大致为直线,表明误差分布接近正态分布。此外,残差图显示线性假设似乎满足恒定的标准偏差。残差直方图做出了明显的正态性假设,因为该图类似于一个以零为中心的正态分布的样本,正态和独立分布的NID (0, σ2)对误差的假设是完成的,因为标准化残差近似正态,平均值为零,单位方差。

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}

The taxonomic study of ants is neglected and poorly investigated from Pakistan but has rich ant fauna, most of the part has been studied before the creation of Pakistan during British Rule including; Bingham (1897), Forel, 1904, Manozi 1939, Eidmann, 1942, Later an expedition undertaken by Brown, (1955) in Baluchistan and Sindh Provinces. Haji (2008) worked on house hold ants of Karachi, Pakistan. More recently Umair et al. 2010 described the ants from Potohar plateau of Punjab Pakistan and Ahmed et al. (2013) provided description on ants of Quetta, Baluchistan. Further, The study is based on comprehensive review of literature, collection and study from throughout country, Author prepare first checklist of ants of Pakistan it is updated with Eight_subfamilies; Dolichoderinae, Dorylinae, Formicinae, Myrmicinae, Proceratiinae Pseudomyrmecinae, Leptanillinae , Ponerinae 43 genera and 134 species.
蚂蚁的分类学研究在巴基斯坦被忽视,调查很少,但有丰富的蚂蚁动物群,其中大部分在英国统治期间巴基斯坦建立之前就已经研究过了,包括;Bingham (1897), Forel (1904), Manozi (1939), Eidmann(1942),后来Brown(1955)在俾路支省和信德省进行了考察。Haji(2008)研究了巴基斯坦卡拉奇的家蚁。最近,Umair等人(2010)描述了来自巴基斯坦旁遮普Potohar高原的蚂蚁,Ahmed等人(2013)描述了俾路支省奎达的蚂蚁。此外,本研究是基于对全国各地的文献、收集和研究的综合回顾,作者编制了第一个巴基斯坦蚂蚁清单,并将其更新为8个亚科;蛭形蝇亚科、蛭形蝇亚科、蚁形蝇亚科、金蝇亚科、伪蝇亚科、细蝇亚科、细蝇亚科43属134种。
