Phrasal Verbs

Phrasal verbs are pervasive in all registers of English and make this language highly idiomatic. Due to their syntactic, semantic, and idiomatic complexity, however, phrasal verbs present an immense learning load even for advanced learners. Their meaning can usually not be derived from the individual meanings of its elements, they are often polysemous and submitted to contextual restrictions. From a contrastive point of view, phrasal verbs correspond only partly to similar constructions in the native languages of German and Italian learners. Both learner groups are thus confronted with a verb type which, on the one hand, is indispensable for idiomatic English but whose teaching, on the other hand, is often neglected in the foreign language classroom. On the basis of detailed quantitative and qualitative analyses of all phrasal verbs extracted from the German and Italian components of the International Corpus of Learner English, the real problems of advanced learners are described. With the consistent comparison of two learner groups, the author aims at contributing to the general understanding of advanced learner language.

Tribological implication of linear dry contact ...

The linear dry contact between glass fiber polymer and steel is one of the most complex. It evolves in time as the wear process is under way. From a qualitative point of view, it is known that an increase in friction leads to an increase in wear. This dependency is clarified only in this paper, both qualitatively and quantitatively, because the increase in contact temperature alongside the increase of normal load induces the transfer of plastic material on the wear metal surface, which leads to a modification of the nature of wear. As a result of the filling consisting of short glass fiber, the characteristic of the wear of the metal surface changes constantly, from abrasive to adhesive, abrasive-adhesive, and finally heavily adhesive and corrosive. In order to capture these aspects, a lot of tests are required, microscopic investigations, measurements and interpretations. This paper has the virtue of finding a global qualitative and quantitative method to present this aspect to everybody, succeeding to present the tribological processes that occur in the case of linear dry sliding contact, in their entire complexity.

Scheduling of real time tasks on clouds is one of the research problem, Where the matching of machines and completion time of the tasks are considered. Cloud computing is an internet-based computing, where resources, softwares and information are shared on demand basis i.e. The user can access documents anytime, anywhere. Real-time computer systems are required to produce correct results not only in their values but also in the times at which the results are produced known as timeliness. Here a quantitative expression of time is used to describe the behavior of the system. Real-time task needs to meet their deadlines regardless of system load or makespan. This text discusses about scheduling of real time task on the cloud environment considering Basic Earliest deadline first (BEDF), FFE (first fit EDF), BFE (best fit EDF), WFE (Worst fit EDF) algorithms. Different performance parameters such as a guarantee ratio (GR), utilization of VMs (UV), throughput (TP) are used to measure the effectiveness of the algorithms

ggf. zzgl. Versand

A new simple, accurate, rapid and precise isocratic Reverse Phase High performance liquid chromatographic (HPLC) method was developed and validated for the determination of Esomeprazole (ESO), and Levosulpiride (LEVO) in capsule formulation. The Method employs Shimadzu HPLC system on Hypercil BDS C18 (25 cm × 4.6 mm i.e., 5 µm) and flow rate of 1 ml/min with a load of 20µl. Acetonitrile and Phosphate buffer was used as mobile phase in the composition of 50:50 at 3.5 PH. The Detection was carried out at 240 nm. Linearity ranges for Esomeprazole and Levosulpiride were 20-60 µg/ml, 37.5-225 µg/ml respectively. Retention Time of Levosulpiride and Esomeprazole were found to be 3.367 min, 4.320 min respectively. Percent Recovery study values of Esomeprazole and Levosulpiride were found to be within 98-102%. This newly developed method was successfully utilized for the Quantitative estimation of Esomeprazole and Levosulpiride in pharmaceutical dosage forms. This method was validated for accuracy, precision, linearity and Robustness as per ICH guidelines.

The impact of Plug-In Hybrid Electric Vehicles ...
49,00 € *
ggf. zzgl. Versand

Plug-In Hybrid Electric Vehicles (PHEVs) have been promoted as a potential technology that can reduce vehicles fuel consumption, decreasing emissions related with the transport sector and dependence from oil importations. However emissions and cost impacts of PHEVs are strictly connected with the power mix generation used to produce electricity and when their batteries are recharged. Potential effects of a PHEV fleet on the power grid have been analyzed under different charging strategies, obtaining a quantitative estimation of the additional load affecting the transmission grid. The environmental impact of these vehicles is estimated for the State of Ohio as well as for other different countries showing the great importance that generation technologies have on PHEVs final environmental performances. Cost analysis shows how these vehicles can obtain great operation cost reduction due to the decrease of gasoline consumption, proposing this technology as a possible solution for decrease oil dependency of the transport sector.

In this research work, samples were collected from 4 stages of leather processing, soaking, liming, deliming & bating. Quantitative bacterial analysis showed that aerobic heterotrophic bacterial load of the samples ranged between 134,000 & 344,000 and 104,000 & 600,000 cfu/ml in NA medium and PYG medium, respectively. Total of 70 bacterial isolates were isolated & based on better proteolytic activity 27 were selected for detail study. All 27 isolates were Gram positive, rod shaped, spore former and Bacillus. In SMA medium proteolytic activity was measured as zone ratio which ranged from 2.61±0.44-6.42±0.95. With better proteolytic activities 4 isolates were confirmed as Bacillus subtilis B20, B. subtilis PB18, B. amyloliqefaciens Egy25 and Bacillus sp. BVC38 based on 16s rDNA sequencing. Alkaline protease production range was 48.38-169.70 U/ml & Bacillus subtilis B20 was the maximum producer. Crude enzymes showed good detergent additive performance & could effectively dehair like the chemicals (lime-sulphide) used for dehairing. 8 isolates showed potentiality in pollution management through decolourization of Acid Brown-75 & Acid Brown-14 dyes.

Lakes of River Indus: Symbols of Negligence
59,00 € *
ggf. zzgl. Versand

This book is about Water Pollution (Microbial and Chemical) of the two lakes (i.e., Haleji and Keenjhar) of river Indus, (Pakistan). Instead of traditional style of any book on water pollution, this book comprises on qualitative and quantitative analysis of water and fish samples. Microbiological examination of water was also performed to assess the total bacterial load along with indicator organisms. In the end, the whole work was summarized, concluded and recommendations are suggested to avoid and prevent further pollution in the water bodies. This book will serve as an excellent source of knowledge for teachers, research scholars, students, NGOs and policy makers who are interested in gaining updated information regarding the important water bodies (as these are the sources of water supplies to the adjacent urban and rural areas as well as for recreational activities).

To address the problem of vehicular pollution in the Kathmandu Valley, the Government of Nepal responded with mainly command and control (CAC) measures such as emissions standards for new and in-use vehicles, banning of new two-stroke motorcycles, and lead phaseout from petrol. Since literature suggested that compared to CAC instruments, economic instruments are cost-effective, this study set out to examine whether fuel tax is indeed preferable. Quantitative analysis was carried out to evaluate the cost- effectiveness of policy measures. Toxicity weightage factors were assigned to the criteria pollutants to derive a composite index of toxic load' inventory while the prevailing costs were used for calculation. The findings of the research were mixed. While banning of new two-stroke motorcycles was found to be most cost-effective, setting of emissions standards for diesel vehicles was least cost-effective. The cost-effectiveness of a fuel tax was calculated for different tax regimes and found to fall in between. It suggested that both categories of instruments should be implemented to achieve the objective with least cost to society.
