Evaluation of Physico-Chemical and Fungal Species Associated with Oil Contaminated Soil from Selected Automobile Garage in Sokoto Metropolis

This study was conducted with a view to evaluating the physicochemical and mycological properties of different oil contaminated soils collected from three different automobile garages in Sokoto Metropolis, and uncontaminated soil from the temporary site, Usmanu Danfodiyo University, Sokoto (UDUS) was used as the control. The pH was determined using pH meter model Hanna (H1991301), quantity of mineral elements was evaluated in accordance with Murphy and Fungi were isolated from the three oil contaminated samples (A, B. and C) and the uncontaminated (sample D) as control, this was done by standard procedure using the method of P. Ren, T. Jankun & B. Leaderer. The physical, chemical, and mineral elements from the oil-contaminated soils of the three automobile garages and control. The results of particle soil analysis revealed the high content of sandy soil (96.2 to 87.3) and silt is the lowest with (2.5–0.6). Magnesium had the highest concentration of studied minerals, ranging from 193 to 649.2 mg/kg. while PH result revealed that the soil samples were pH value ranged from (16.85–16.20) in oil Contaminated samples, while the control had 15.90, and electrical conductivity ranged from 12.8–13.8 % and 28 % in control, four fungal isolates Aspergillus sp., Penicillum sp., Mucor sp. and Sporobolomyces sp. were identified based on colonial, sexual and morphological characteristics. These fungal strains can be used in bioremediation process and oil pollution reduction in aquatic ecosystems

A Bibliometric Analysis of the Top 100 Cited Articles on Hepatic Magnetic Resonance Imaging.

The purpose of this study is to guide the readers to the impact of the articles published on hepatic magnetic resonance imaging (MRI). We searched Scopus using 10 different search terms for hepatic MRI. The selected studies were thoroughly reviewed by two independent authors and any disagreement was sorted out by mutual consensus. The list of articles and journals was downloaded into an excel spreadsheet. Only the top 100 cited articles were selected by mutual consensus among all the authors. These articles were further read in the full-text form and were further categorized into subgroups. Three authors independently reviewed the top 100 selected articles, and subsequently data was extracted from them and analyzed. Our study showed that the highest number of top 100 cited articles on hepatic MRI were from Radiology (30 articles) followed by European Radiology (14 articles). The American Journal of Roentgenology, Radiographics, and Journal of Magnetic Resonance had seven articles each. The United States had the highest number of articles by region. Nineteen other journals contributed only one article each to the list of top 100 cited articles. The contribution of authors to the top 100 cited articles was reviewed; all the authors contributing with more than two articles to the highly cited articles are given in Table 3 in the supplementary material. The maximum number of articles were published during 2009 (14 articles), and for a five-year period, the maximum contribution was made during 2008-2013 (44 articles). Our analysis gives an insight on the frequency of citations of top articles on hepatic MRI, categorizes the subtopics, the timeline of the publications, and contributions from different geographic distributions

Antifungal and antispasmodic activities of the extracts of Euphorbia granulata

The dichloromethane and methanolic extracts of the plant Euphorbia granulata were investigated for their antifungal, antibacterial, phytotoxic, brine-shrimp cytotoxic, antioxidant, spasmolytic (antispasmodic) and acetylcholinestrase inhibitory activities. The dichloromethane extract showed strong inhibition against Microsporum canis (90%) and against Aspergillus flavus (50%). Both the extracts inhibited the spontaneous contractions in rabbit jejunum preparations with EC50 value of 0.17 and 1.3 mg/mL, respectively and also relaxed the K+-induced contractions with EC50 0.2 and 2.8 mg/mL, respectively, suggesting a calcium channel blocking activity. However, the extracts did not show antibacterial, phytotoxic, brine-shrimp cytotoxic, antioxidant and acetylcholinestrase inhibitory activities

Role of Relationship Marketing in Building Customer Loyalty in Services Sector of Pakistan

The basic aim of this study is to unfold the emerging importance of relationship marketing in the present era and build trust and relationship commitment for the customer loyalty for successful relational exchange. The idea was to determine the differential effects of trust, perceived service quality and relationship commitment on customer loyalty. This paper also includes the service quality antecedents and their effect on the loyalty of the customer. The proposed model has been tested with adapted survey questionnaire in context of insurance sector service. The sample size was 100 respondents having insurance policy of two renowned life insurance companies of the country. The regression analysis and PCA (Principle Component Analysis) was performed. This approach of single industry may create the internal validity of the proposed model, repetition in alternative service settings is required to upsurge the generalizability of the results. The results underwrite to understanding of the relationships between dissimilar elements of trust, service quality, relationship commitment, and customer loyalty; offer critical inferences for managers of service organizations; and climax directions for future research. This also helps to understand the firm’s intentions towards the quality and the role quality in customer loyalty.

Extension of Tinny Application for Cloud Based Custom Software with Encryption Queue: A Strategy to Protect Data on Cloud

Data protection is in your hands, even your data lands in the lap of service providers. Cloud computing is a new and emerging concept in the field of IT. It means do everything over the internet and put burden on the shoulders of cloud's service providers. Individuals or business organizations are hesitant to do their tasks over public networks like internet. They can't leave their sensitive data in the hands of service providers. It is due to lack of confidence and trust on service providers. Protecting customer's sensitive data on cloud is the major issue. Here authors purposed a strategy to protect customer's sensitive data before sending it towards service providers. The strategy consists of a barrier (Encryption Queue) to protect customer's data. With the use of this strategy, encryption procedure will be in the hands of customers themselves. This concept will help to built up customer's trust and will prepare them to shift desktop based applications over the cloud
