And really good analyses of the travels of ideas-like François Cusset's French Theory, an account of the way that French thought was taken up in the U.S. during the 1970s and 1980s-are valuable for what they tell us of the meeting between people, institutions and concepts. The trajectory of translation studies, when its arc one day becomes clear, will also be a revealing chapter in the history of ideas. But for the moment, its travels still seem to be full of surprising twists. And one of these is the increasing importance of "cultural translation" as a platform of analysis, especially in the European context. The rich collection of articles found on the eipcp website is striking

Among all the peptides, DM3 conferred protection to a substantial proportion of the lethally infected mice caused by a strain of penicillin-resistant Streptococcus pneumoniae. Synergism was reported and therapeutic efficacy was significantly enhanced when DM3 was formulated in combination with penicillin (PEN). No toxicity was observed in mice receiving these treatments. The in silico molecular docking study results showed that, DM3 has a strong affinity towards three protein targets; autolysin and pneumococcal surface protein A (pspA). Thus AMPs could serve as supporting therapeutics in combination with conventional antibiotics to enhance treatment outcome.

S2003-US-778, S2003-US-127, S2006-US-641, S2006-US-832 and check clone (HSF-240) was evaluated at the Sugarcane Research Institute, AARI, Faisalabad, Pakistan. Plant crop was harvested on 1st November, 1st December, 1st January, 1st February and 1st March in 2010-2011 and subsequent ratoon crop was harvested in January, 2012. It was observed that number of millable canes, cane yield and commercial cane sugar (CCS) varied significantly among all the harvesting dates and highest cane yield (56.25 t ha-1) was recorded in case of February ratooned crop along with overall sugar yield of 7.35 t ha-1. Whereas, similar cane yield was observed in case of genotypes S2003-US-778, S2003-US-127 and check (HSF-240) cultivar which was significantly higher than others. February ratooned crop produced highest cane and sugar yield among all harvesting dates for all the genotypes.

For this purpose, we select three extensively utilized proactive protocols; Destination-Sequenced Distance Vector (DSDV), Optimized Link State Routing (OLSR) and Fish-eye State Routing (FSR). We also enhance the performance of these protocols by modifying their default parameters. All experiments for evaluating and comparing the performance of protocols are performed in NS-2. Optimization of these routing protocols is done via performance metrics; average Throughput, End to End Delay (E2ED) and Normalized Routing Load (NRL) achieved by them. Default routing protocols DSDV, OLSR and FSR and compared and evaluated with modified versions named as M-DSDV, M-OLSR and M-FSR. Numerical Computations for Route Stabilities of these routing protocols through a mathematical modeled equation is determined and then compared with the results obtained through Simulations in NS-2.

The main goal of the object recognition problem is to recognize the objects of the same type even when they are viewed from different viewpoints. This goal, however, remains a challenge for computer vision to recognize objects having invariant features such as translation, rotation and scaling. Shape descriptors like Fourier and Moments are invariant with respect to transformation, rotation and scaling. One of the most important tasks regarding to object recognition is how to find number of descriptors of a given object. The query that arises is what is the optimum number of descriptors to be used with maximum recognition rate? , Are descriptors having equal importance? Such reasons signify the importance of these descriptors and also selecting the best descriptor by applying optimization technique.

Numerical Computations for Route Stabilities of these routing protocols through a mathematical modeled equation is determined and then compared with the results obtained through Simulations in NS-2. Moreover, all-inclusive evaluation and scrutiny of these proactive routing protocols are done under the Mac layer standards 802.11 DCF and 802.11e EDCF. In this way both Network and Mac layer exploration has been done under the performance metrics which gives overall performance and tradeoff with respect to full utilization of the available resources of Ad-hoc network high scalability scenario. Routing latency effects with respect to route stabilities and Mac layer standards 802.11 and 802.11e are compared and scrutinized with the tradeoff observed in throughput and in overhead (NRL) generated.

The main goal of the object recognition problem is to recognize the objects of the same type even when they are viewed from different viewpoints. This goal, however, remains a challenge for computer vision to recognize objects having invariant features such as translation, rotation and scaling. Shape descriptors like Fourier and Moments are invariant with respect to transformation, rotation and scaling. Particle swarm optimization (PSO) is a population based soft computing technique. Particle Swarm Optimization technique shares numerous similarities with evolutionary computation techniques such as Genetic Algorithms (GA). One of the most important tasks regarding to object recognition is how to find number of descriptors of a given object. The query that arises is what is the optimum number of descriptors to be used with maximum recognition rate? , Are descriptors having equal importance? Such reasons signify the importance of these descriptors and also selecting the best descriptor by applying optimization technique. We have introduced an evolutionary optimization technique known as Genetic algorithm (GA) for solving the optimization problem. GA assigns, for each of these descriptors, a weighting factor that reflects the relative importance of that descriptor.

The circumstances of similarity transformations, presence of noise, and occlusion have been included as the part of the study. For simplicity, instead of objects, outlines of the objects have been used for the whole process of the recognition. Fourier Descriptors have been used as features of the objects. From the analysis and results using Fourier Descriptors, the following questions arise: What is the optimum number of descriptors to be used? Are these descriptors of equal importance? To answer these questions, the problem of selecting the best descriptors has been formulated as an optimization problem. Genetic Algorithm technique has been mapped and used successfully to have an object recognition system using minimal number of Fourier Descriptors. The proposed method assigns, for each of these descriptors, a weighting factor that reflects the relative importance of that descriptor.

The integration of a negatively charged probe molecule on the poly-DAN/GO/AuNPs nanohybrid attained the signal enhancement to discriminate dopamine (DA) molecules from foreign species by catalytic effect and surface charge, and hydrogen bonding-based interactions with a probe molecule. The sensor performance and morphology were investigated using voltammetry, impedance spectrometry, SEM, and XPS. Experimental variables affecting the analytical performance of the sensor probe were optimized, and linear response was observed in the range of 10nM-1µM with a detection limit of 5.0nM (±0.01) for DA. Then, the sensor was applied to monitor dopamine released from PC12 cells upon extracellular stimula...

Suppression subtractive hybridization was carried out on root cDNA from bulked boron tolerant and intolerant doubled haploid barley lines grown under moderate boron stress to identify genes associated with boron tolerance. One hundred and eleven clones representing known proteins were found to be up-regulated in the tolerant bulk upon boron stress. Nine clones were genetically mapped to previously reported boron tolerance QTL. These include a clone identical to the boron transporter gene Bot1 and a clone coding for a bromo-adjacent homology domain-containing protein, mapping to the 6H boron tolerance locus and co-segregating with reduced boron intake in a Clipper ¥ Sahara-3771 mapping population. A third clone mapping to the 2H QTL region encoding an S-adenosylmethionine decarboxylase precursor was found to provide tolerance to high boron by heterologous expression. Yeast cells expressing Sahara SAMDC were able to grow on 15 mM boron solid media and maintained cellular boron concentrations at 13% lower than control cells expressing empty vector. The data suggest that an antioxidative response mechanism involving polyamines and the ascorbate-glutathione pathway in Sahara barley may provide an advantage in tolerating high soil concentrations of boron.

In the first step 8-methyl-2H-pyrido[1,2-a]pyrimidine-2,4(3H)-dione (1) was prepared by reacting 4-methyl-2-aminopyridine, with diethylmalonate. Compounds substituted pyrido[1,2-a]pyrimidine-2,4(3H)-diones (PPMDO) (2)-(17) were prepared by condensing 8-methyl-2H-pyrido[1,2-a] pyrimidine-2,4(3H)-dione in the presence of triethylorthoformte (TEF) and dimethylformamide (DMF), with respective amino components viz. 2-aminoacetophenone, 3-aminoacetophenone, 4-aminoacetophenone, 2,4,6-trimethylaniline, 2-fluoroaniline, 3-fluoroaniline, 4-fluoroaniline, 2-aminothiophenol, 2-amino-4-methylpyridine, 2-amino-5-methylpyridine, 2-amino-5-nitropyridine, Benzoic hydrazide, 4-nitrobenzoic hydrazide, 4-bromobenzoic hydrazide, 4-chlorobenzoic hydrazide and 4-hydroxybenzoic hydrazide, respectively. The chemical structures of all the compounds were elucidated by IR, 1 H-NMR, 13 C-NMR and elemental analysis data. The synthesized compounds were screened for their in vitro urease inhibition activity, by the phenol hypochlorite method. These compounds were found to exhibit either no or low to moderate or significant activity. The compounds and showed comparatively much higher activity. However, the compound (9) was found to be the most active one.
