Improved description and monitoring of near surface hazardous infiltrate complexes by shear waves for effective containment reponse
Among numerous causes of fluid releases and infiltration in near surface, resurgence in such anthropic activities associated with unconventional resource developments have brought about a resounding concern. Apart from the risk of an immediate chemical hazard, a long term possible recurrent geo-environmental risk since can also be envisaged as for various prevalent stake holders and broader initiatives. Urgency and exactness for spatiotemporal containment and remediation promotes the devising of efficient methods for monitoring near subsurface flow complexes caused by such spills. Swave (Shear waves) spectral imaging results, in relevant context, of a controlled immiscible fluid displacement monitoring experimental study are analysed and inferred. Against the prospective method as well evaluated, Swave diffraction associated spectral peculiarities are examined, importantly, given background medium characteristics definitions invoking fresh insights of microscale significance alongside macroscale potential
EMERGENCE OF CARBAPENEM RESISTANT ENTEROBACTERIACEAE IN ABU DHABI, 2009-2015
The rapid emergence of carbapenem resistant Enterobacteriaceae (CRE) is a global phenomenon that has not spared the United Arab Emirates. However, unlike in most Western countries with similarly developed health care system, very little data have been available locally on the rate and dynamics of antimicrobial resistance in general, and that of CRE, in particular. Our laboratory has been collecting CRE isolates from Abu Dhabi hospitals since 2009. In the current study we subjected 394 such independent strains, representing 34.0% of the total CRE encountered, to a detailed analysis that included the determination of their antibiotic susceptibility profile, of the type and alleles of the carbapenemases produced, of the pulsotypes and multi locus sequence types of the strains, respectively. 84.0% of the strains produced a carbapenemase. The most common type was OXA-48-like (43.9%) followed by NDM (24.9%). A high rate of double carbapenemase producers (14.5%) was also observed, while no KPC and IMP were encountered. Regarding the specific alleles, OXA-232 and NDM-1 were the most common ones. 16.2% of the strains exhibited non-susceptibility to colistin, while 57.6% to tigecycline, 29.4% exhibited extreme- (XDR), while 5.6% pan-resistance (PDR). Seven major Klebsiella pneumoniae clones were identified: ST14 (n=111), CC147 (n=43), ST231 (n=36), CC101 (n=16), ST11 (n=8), ST45 (n=8) and ST15 (n=5), representing 70.1% of all K. pneumoniae, and 57.6% of all strains encountered. Representatives of these clones were present in majority of the hospitals. The emergence and spread of these clones considerably impacted the local epidemiology of CRE as, in general, they were more likely to be XDR or PDR than the rest of the collection.
Our data show that Abu Dhabi is facing a severe CRE problem. Only a continuous surveillance supported with molecular typing data, as those generated by the current study, could offer the background to successfully control the problem

Static Trade-off theory or Pecking order theory which one suits best to the financial sector. Evidence from Pakistan.
This research is a contribution towards understanding the financial behavior of leasing sector of Pakistan for the period of 2001-2010. It is an attempt to investigate the key factors that influence the capital structure of leasing sector of Pakistan. Financial Leverage is taken as the dependent variable. Whereas, Size of Firm, Capital intensity; Liquidity, Profitability and Tangibility of assets are taken as independent variables. Empirically it has been found that size of assets has a negative and significant impact on leverage. It has also been found that Liquidity, Tangibility, profitability and capital intensity do not significantly influence Leverage. Hence, it is concluded that leasing sector of Pakistan is following Pecking Order Theory in terms of the Size of Firm, Tangibility, liquidity, profitability and capital intensity. Key words: Leasing, financial sector, Karachi Stock Exchange, Tangibility, Pecking Order Theory, Static Order Theor
Outsourcing Decision in Capabilities Perspective
There are many theories and framework which suggest performance link to strategy and / or resources. In order to succeed in the market, the organization must transform its core strengths into competitive advantages so that it becomes harder for its rivals to snatch its customers and market share. This paper has attempted to integrate the issue of weakness emanating out of the capability frame in terms of strategic decision in outsourcing. With the help of our proposed “Integrated Decision Making Model” for strategic outsourcing,, significant advantage can be achieved by directing investments and efforts in areas where firms perform better as compared to others. Over time, a continued effort to develop core competencies by building strategic capabilities (strengths) and minimizing strategic liabilities (weaknesses), bar the present or future competitors to expand into the company's areas of interest, thus helps to defend the strategic competitive advantages lying in the firm's value chain

Gamma Radiolytic Degradation of 4-Chlorophenol Determination of Degraded Products with HPLC and GC-MS
Contamination by chlorophenols of surface water and groundwater is an emerging issue in environmental science and engineering. After their usage as pesticide, herbicide and disinfectant, these organic compounds subsequently enter the aquatic environment through a number of routes. Some of the chlorophenols are slightly biodegradable, while others are more persistent and mobile in the aquatic environment especially chlorophenols. Gamma radiolytic degradation is one of advance oxidation process that has been thought to be one of the promising treatments to deal with this problem. This radiolytic study was carried out in methanolic 4-CP (4-chlorophenol) samples. Among several factors effecting radiolytic degradation of 4-CP, dose and concentration are important that were evaluated under atmospheric conditions. A degradation yield (G –value) for 4-CP of 0.38 and 1.35 was achieved in 20 and 100mg/dm3 solution. It was observed that degradation yield decreases with increasing 4-CP concentration. Gamma radiolysis produce free radicals in solvent which further react with 4-CP molecules to generate different products. The identification of degradation products was proposed using HPLC and GC-MS
An analysis into the Stock Selectivity skill of Indian Fund Managers
With the increasing emphasis on domestic savings and improvement in the deployment of investments through markets, the need and scope for mutual fund operation has increased tremendously. The mutual fund is a vehicle that enables millions of small and large savers spread across the country as well as internationally to participate in and derive the benefit of the capital market growth. It is an alternative vehicle of intermediation between the suppliers and users of investible resources. The vehicle is becoming increasingly popular in India and abroad due to higher investor return, relatively lower risk and cost. Thus the involvement of mutual funds in the transformation of Indian economy has made it urgent to view their services not only as the financial intermediary but also as pacesetters as they are playing a significant role in spreading equity culture.
In India, the mutual fund industry started with the setting up of the erstwhile Unit Trust of India in 1963. Public sector banks and financial institutions were allowed to establish mutual funds in 1987. Since 1993, the private sector and foreign institutions were permitted to set up mutual funds. In February 2003, following the repeal of the Unit Trust of India Act 1963 UTI was bifurcated into two separate entities. One is the Specified Undertaking of the Unit Trust of India with assets under management of Rs 29,835 crores as at the end of January 2003, representing broadly, the assets of US 64 scheme, assured return and certain other schemes. The Specified Undertaking of Unit Trust of India, functioning under an administrator and under the rules framed by Government of India doesn't come under the purview of the Mutual Fund Regulations. The second is the UTI Mutual Fund, sponsored by SBI, PNB, BOB, and LIC. It is registered with SEBI and functions under the Mutual Fund Regulations
