Subject: Setting Electricity gee ration targets: Some concerns
Keywords: Electricity generation targets
Abstract: Rethinaraj and Ahuja (hereinafter RA), have proposed ‘optimal targets’ for per capita electricity use. In 1985, Goldemberg et al.(hereinafter GJRW) proposed that a target of 1840 kWh per capita per annum for electricity use would be adequate to ensure basic human comfort in the developing counties. Quoting GJRW, RA opine that with current efficiency improvement s and appliance standards, 1840 kWh per capita per annum should provide more than what was envisaged by GJRW. The figure arrived at by the GJRW based on a thought experiment needs analysis and its extrapolation by RA is erroneous. GJRW list activities to be pursued by a person living in the developing world, and have come up with a figure of 1.049 kW (about 33 Gj per annum) per capita as the total final energy requirement.

Abstract: The present study investigates how the ' fission-fusion-adapted ' bonobos and Bornean orangutans manage social relationships when kept under permanent group-living conditions. Our results showed that the bonobos and orangutans did not differ in the overall frequency of dyadic interactions. The orangutans evidently realized a potential to interact with partners, which on a surface a potential to interact with partners, which on a surface did not differ from what was found in the bonobos. However, the bonobos spent more time on sociopositive interactions, especially on grooming and sit in contact, where as the orangutans agonistically interacted with each other more often. Though frequencies of approaching were similar between the two species, orangutans actively left the proximity to a partner more often than the bonobos, which in turn were more often in spatial proximity. The three groups of bonobos housed under different conditions differed from each other for sociopositive and agonistic interactions. The orangutans differed for agonistic but not for sociopositive interactions. As a striking difference between the species, it appeared that between subadult/adult orangutans, behaviours which required prolonged body contact occurred only rarely and briefly. Differences in bonding patterns have been discussed as possible explanatory factor. The ' short and distant nature ' of interactions between adult orangutans suggests the existence of social relationships, the management of which requires less ' servicing behaviours ' . Subadult/adult orangutans may be less attracted by each other than individuals in more gregarious species: that may have the cognitive skills to interact, but may not be motivated to stay together for long.

Subject: Virological perspective and characterization of seasonal influenza B viruses in Mumbai.
Keywords: Classification and domains analysis, hominids, kinome, protein kinases.
Abstract: A comparative analysis of protein kinases encoded in the human genome and those of the closest evolutionary relatives such as chimpanzee, gorilla and orangutan is made in the present study. Sequence comparisons of humans with their closest lineages are of considerable interest in order to understand the ambulatory mechanism behind the evolutionary relationship of apes. A total of 499, 478, 468 and 470 protein kinases from human, chimpanzee, gorilla and orangutan genomes respectively, which include both eukaryotic protein kinases and atypical protein kinases were analysed. Classification of their groups and families reveals the presence of three highly populated protein kinase families, namely STE20, CAMKL, CDK11A, C9orf96, PDK1, PDK2 and TAF1 in humans. Domain organization of each of the protein kinases in the four genomes show the presence of frequently occurring domains such as SH2 domain, immunoglobulin-I set domain, phorbol esters/diacylglycerol binding domain (C1 domain), and SH3 domain in all four genomes, and unusual domain architectures for few human atypical protein kinases such as BCKDK, PDK1 and PDK2.This hominid-based comparative study will provide valuable insights into the similarities and differences between humans and three other non-human apes in kinome-level ranking and functional aspects and a base for experimental analysis on hominids in order to enhance our understanding on their specific biological roles.

Subject: Virological perspective and characterization of seasonal influenza B viruses in Mumbai.
Keywords: Acute respiratory infections, influenza virus, serotype, virological perspectives.
Abstract: Acute respiratory infections caused by influenza viruses are major life-threatening infections affecting the global population. Information on influenza viruses in Mumbai region in India is limited. With an estimated population above one crore, it becomes imperative to identify the predominant circulating strains, seasonal evolution, epidemiology and impact of influenza virus infection on the public health of Mumbai. The present study is aimed to isolate and identify The prevalent influenza B virus strains circulating in the Mumbai region. Virological analysis of 482 throat and nasal samples from patients presenting with suspected influenza-like illness was conducted from January to December 2012 at a research institute in Mumbai. Isolation of positive influenza B samples was performed on Madin Darby Canine Kidney (MDCK) cell line. The isolates were further characterized by hemagglutination inhibition assay and one-step reverse transcriptase polymerase chain reaction. Among all the specimens tested, 71 % were positive for influenza virus. The positivity for influenza B virus, influenza A (H1N1) pdm 09 and seasonal influenza A virus was 38 %, 22 % and 11% respectively. Of the 80 influenza B specimens cultured on MDCK, virus was isolated from 38 (48%) samples. Influenza B/Wisconsin/1/2010-like serotype belonging to the B/Yamagata/18/88 lineage was the predominant serotype identified. Influenza was a significant public health concern in the Mumbai region during the study period. Young children were the most affected age group. The study data generated will help understand the epidemiology of the disease in the Mumbai region as well as generate information for global influenza surveillance.

Subject: Effective estimation of GAGAN signals with adaptive equalization
Keywords: Lateral placement, speed, TRAZER, video image processing system
Abstract: With the advancements in video image processing system (VIPS), detection mechanism has made a significant improvement over traditional methods for traffic data analysis. Traffic on Delhi-Gurgaon expressway is heterogeneous in nature with non-lane based behaviour. Moreover, automation and instrumentation are also not implemented. In view of this, TRafic AnalyZer an EnumeratoR (TRAZER), VIPS was used to process video-captured data on Delhi-Gurgaon expressway to check accuracy based on traffic count, speed and lateral placement. The motivation behind using TRAZER is to evaluate its efficiency and robustness for extracting micro and macro-level traffic parameters under heterogeneous traffic conditions. To achieve this, data were extracted manually on above parameters and compared with those obtained from TRAZER. The volume count data from TRAZER generated a lesser accuracy of 60 % detection under heavy traffic conditions, using default parameters. Thus, refinements were carried out in the software as part of calibration: (i) redefining maximum and minimum detection widths for each vehicle category, and (ii) selecting the optimum trap length for reducing the occlusion effect, which increased the detection percentage as well as reduced the error. After implementing these refinements, 80 % of the vehicles were detected. Further, relationships between vehicle speed and its lateral placement from median across road width, at a given point were also developed. The models were developed for both aggregate (considering all vehicles) and disaggregate (vehicle category-wise) levels. The polynomials relationship was found to be best fitted function to estimate vehicle speed based on its lateral placement.

Abstract: The study aims at evaluating the effect of particle size and thermal treatment on printed circuit boards (PCBs) of Mother Board (MB) and DVD on metal extraction. Results show around 90-95 % (w/w) and 35-40 % (w/w) of total Al and Cu respectively, in CPU could be recovered by systematized disassembly. Remaining embedded Al and Cu require metallurgical or hydro-metallurgical processing. Cu extraction increases with size reduction. Thermal treatment of MB-PCB shows reduction in Cu extraction (23-38%) for all sizes in comparison without thermal treatment, while DVD-PCB showed surge in extraction after thermal treatment (41-141%) in comparison without thermal treatment.

Abstract: To evaluate therapeutic efficacy of Achyranthes aspera against arsenic toxicity, mice were given aqueous root and leaf extracts at both low and high doses (100 and 200 mg.kg body wt) after being intoxicated with sodium arsenate (0.1 mg/kg body wt.).Significant alterations (P<0.05, 0.001) were seen in various haematological parameters, Ig level, macrophage yield, viability, phagocytic index and progesterone level. Results clearly depicts that both A.aspra extracts significantly restore the unbalanced level up to the normal. This study shows the protective efficacy of A.aspera on altered haematological and immunological system. It is possible that future work on drug formulation may use this plant as a source.

Subject: Delineation of groundwater saturation indicators and their distributions in the complex argillaceous geological units of Ezza north local government area of Ebonyi state, Nigeria.
Keywords: Argillaceous geological units, groundwater potential, hydrogeological properties, vertical electrical sounding.
Abstract: Twelve vertical electrical soundings (VES) employing Schlumberger electrode configuration were carried out inparts of Ezza north local government area of Ebonyi state, Nigeria ,where extraction of potable groundwater has posed challenges to the dwellers of the area who are currently relying on surface water sources and some scattered seasonal open wells that cause health problems. The present study was under-taken to determine the hydrogeological characteristics, indicators that predict groundwater potential of the study area. The study indicates that the aquifer resistivity ranges between 12 and 504 ? m with an average value of 95.42 ?m with an average of 26.34 ?m. The aquifer thickness ranges from 34.1 to 214.7 m with an average of 71.97 m. Also, the formation factor varies between 1.25 and 6.9 with an average of 2.76.Porosity ranges between 5.34 % and 29.47 % with an average of 15.91 %. Similarly, hydraulic conductivity ranges from 1.1645 to 38.0491 m/day, the average being 12.8312 m/day, and ? values range between 0.0023 and 3.1695 S/day with a mean value of 0.6273 S/day. Using surfer software package, contour distributions of geo-hydrodynamic properties were generated which show the distribution of the aquifer parameters in the study area. The distributions of these properties reflect the regions with high and low potential groundwater in the area. The diagnostic models and the inherent and intrinsic constants can be employed in quantitative prediction of groundwater potential in the adjoining regions of the study area which show similar hydrogeological properties.
