International Journal of Bioassays , 2012,
Abstract: The present study was planned to assess the levels of oxidant and antioxidant in various lung disorders and to evaluate the existence of correlation between oxidant-antioxidant levels. Asthma, Bronchitis, COPD and Lung fibrosis well know chronic inflammatory disorders where disturbances in the oxidative system have been observed. To investigate the lipidperoxidation in terms of plasma MDA and antioxidant capacity in terms of ascorbic acid (Vitamin C) were measured. Results revealed statistically significantly Increase serum MDA (P<0.001) and decrease vitamin C (P<0.001) in patients suggestive of oxidative imbalance in various lung disorders was revealed. However there is negative correlation between lipidperoxidation and ascorbic acid levels correlation. The study thus supported the emerging concept of free radical injury in various lung disorders and therefore a thought can be given to whether antioxidant supply could have a beneficial impact on the free radical induced injury and improvement of respiratory reserve in various lung disorders.

International Journal of Bioassays , 2012,
Abstract: Diabetic patients with accompanied (but often unnoticed) dyslipidemia are soft targets of cardiovascular deaths. An early intervention to normalize circulating lipids shown to reduce cardiovascular complications and mortality. Now a day’s Glycated albumin (GA) is a routinely used marker for short-term glycemic control. This investigation is an attempt to evaluate the association between GA and various lipid parameters. Venous blood samples collected from 100 type-2 diabetic patients (46 males, 44 females) and serum analyzed for GA, Fasting blood glucose, Total Cholesterol, Triacylglycerols, HDL-C and LDL-C. L/H risk ratio is also calculated. The levels of GA (%) did not differ significantly between males (8.51 ± 1.17) and females (8.24 ± 1.89), whereas male patients had higher mean values of FBG and various lipid parameters than in females. Patients with GA value >17.0 % showed direct and significant correlation with FBG, TC, LDL-C, L/H risk ratio as compared to patients with GA ≤ 17.0%. There was no significant difference in TG, HDL-C between two groups of glycated albumin. These findings indicate that GA is utilized for screening high risk diabetic patients for early diagnosis of dyslipidemia and timely intervention with lipid lowering drugs.
INDIGENOUS EFFECT OF CYNODON DACTYLON IN EXPERIMENTAL INDUCED ULCERS AND GASTRIC SECRETIONS
Kondaveeti Suresh Babu,Ivvala Anand Shaker,Dabburu Kumaraswamy,S.Saleem Basha
International Research Journal of Pharmacy , 2012,
Abstract: Cynodon dactylon is a perinneal grass,the plant is a rich source of metabolites such as proteins,carbohydrates mineral constituents, β-sitosterols, flavinoids, alkaloids, glycosides and triterpenoids the plant has been long used in traditional medicines to treat various alignments it also has antiviral and antimicrobial properties but none has proved its efficacy in evaluating gastro protective activity so we had made an attempt to evaluate the gastroprotective effect of extract of Cynodon dactylon in albino rats. The experiment was set up using male albino wistar rats weighing 150-180gms. These were further divided evenly into different treatment groups. The extract of Cynodon dactylon was investigated for its anti- ulcer activity against pylorus ligation, aspirin induced and ethanol induced gastric ulcer in rats at 100,200, 300mg/kg body weight. Histopathological assessment of rat stomach was carried out. A significant reduction (p<0.01) in ulcer index was seen in Cynodon dactylon extract treated rats of pylorus ligation, aspirin induced and ethanol induced gastric ulcer models. The gastroprotective effect was further confirmed by histopathological examination of rat stomach. Thus the present study concludes the Cynodon dactylon extract having potential gastroprotective effect in the three models tested.

International Journal of Computer Technology and Electronics Engineering , 2012,
Abstract: Web databases contain a huge amount ofstructured data which are easily obtained via their queryinterfaces only. Query results are presented indynamically generated web pages, usually in the form ofdata records, for human use. Decisive for web dataintegration applications is the problem of automaticallyextracting data records from query result pages, such ascomparison shopping sites, meta-search engines, etc. Anumber of approaches to query result extraction havebeen proposed. As the structures of web pages becomemore critical, these approaches start to fail. Query resultpages usually also contain other types of information inaddition to query results, e.g., advertisements, navigationbar, etc. Most of the existing approaches do not move outsuch impertinent contents which may affect the accuracyof data record extraction. We have observed that queryresults are usually displayed in regular visual patternsand terms used in a query often reappear in query results.
Experimental Investigations and Theoretical Modeling Aspects in Column Studies for Removal of Cr(VI) from Aqueous Solutions Using Activated Tamarind Seeds  [PDF]
Suresh Gupta, B. V. Babu
Journal of Water Resource and Protection (JWARP) , 2010, DOI: 10.4236/jwarp.2010.28081
Abstract: Continuous adsorption experiments are conducted using fixed-bed adsorption column to evaluate the performance of the adsorbent developed (from activated tamarind seeds) for the removal of Cr(VI) from aqueous solutions and the results obtained are validated with a model developed in this study. The effects of significant parameters such as flow rate, mass of adsorbent, and initial Cr(VI) concentration are studied and breakthrough curves are obtained. As the flow rate increases from 10 to 20 mL min-1, the breakthrough time decreases from 210 to 80 min. As the mass of adsorbent increases, breakthrough time gets delayed. The breakthrough times are obtained as 110, 115 and 210 min for 15, 20 and 25 g of activated tamarind seeds. As the initial Cr(VI) concentration increases from 100 to 200 mgL-1, the break point time decreases from 210 to 45 min. The process parameters for fixed-bed adsorption such as breakthrough time, total percentage removal of Cr(VI), adsorption exhaustion rate and fraction of unused bed length are calculated and the performance of fixed-bed adsorption column is analyzed. The mechanism for Cr(VI) adsorption on activated tamarind seeds is proposed. At low value of solution pH (= 1), the increase in Cr(VI) adsorption is due to the electrostatic attraction between positively charged groups of activated tamarind seeds and the HCrO4-. A mathematical model for fixed-bed adsorption column is proposed by incorporating the effect of velocity variation along the bed length in the existing model. Pore and surface diffusion models are used to describe the intra-particle mechanism for Cr(VI) adsorption. The breakthrough curve obtained theoretically from pore diffusion model and surface diffusion model are compared with experimental results for different operating conditions. The standard deviation values obtained for pore diffusion model and solid diffusion model are 0.111 and 0.214 respectively.
Aid Effectiveness and Capacity Development: Implications for Economic Growth in Developing Countries  [PDF]
Prabuddha Sanyal, Suresh C. Babu
Modern Economy (ME) , 2012, DOI: 10.4236/me.2012.35075
Abstract: In this paper, we present a stylized model for understanding the relationship between capacity strengthening and eco-nomic growth in an endogenous growth framework. Endogenous growth theory provides a novel starting point for combining individual, organizational, and enabling environmental issues as part of attaining the capacity-strengthening goal. Our results indicate that although donors can play an important role in aiding countries to develop their existing capacities or to generate new ones, under certain conditions, the potential also exists for uncoordinated and fragmented donor activities to erode country capacities. From the policy exercises, we demonstrate that improving economy-wide learning unambiguously increases the rate of growth of output, technology, capital stock, and capacity. Moreover, a donor’s intervention has the maximum impact on the above variables when the economy’s capacity is relatively low. In contrast, donor intervention can lead to “crowding-out effects” when the economy’s capacity is moderately high. Under such a situation, the economy never reaches a new steady state. Our results not only lend support to diminishing returns to aid but also to an S model of development aid and country capacity relationship.
Clock Synchronization in Digital Circuits
1N. Suresh Kumar, Member, IEEE, 2G. Babu Rao, 3K.V. Ramana Rao, 4Anil P
International Journal of Engineering Trends and Technology , 2011,
Abstract: There are different ways to operate digital circuits to achieve good propagation of data. In recent days most of the digital circuits are failing to synchronize the clock with data waves. The clock pulse must be given in proper time period, almost equal to the data propagation speed or arrival time of the data to the next stage. In the present paper a new method is proposed to synchronize the speed between data and clock pulses
NEXCADE: Perturbation Analysis for Complex Networks
Gitanjali Yadav, Suresh Babu
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0041827
Abstract: Recent advances in network theory have led to considerable progress in our understanding of complex real world systems and their behavior in response to external threats or fluctuations. Much of this research has been invigorated by demonstration of the ‘robust, yet fragile’ nature of cellular and large-scale systems transcending biology, sociology, and ecology, through application of the network theory to diverse interactions observed in nature such as plant-pollinator, seed-dispersal agent and host-parasite relationships. In this work, we report the development of NEXCADE, an automated and interactive program for inducing disturbances into complex systems defined by networks, focusing on the changes in global network topology and connectivity as a function of the perturbation. NEXCADE uses a graph theoretical approach to simulate perturbations in a user-defined manner, singly, in clusters, or sequentially. To demonstrate the promise it holds for broader adoption by the research community, we provide pre-simulated examples from diverse real-world networks including eukaryotic protein-protein interaction networks, fungal biochemical networks, a variety of ecological food webs in nature as well as social networks. NEXCADE not only enables network visualization at every step of the targeted attacks, but also allows risk assessment, i.e. identification of nodes critical for the robustness of the system of interest, in order to devise and implement context-based strategies for restructuring a network, or to achieve resilience against link or node failures. Source code and license for the software, designed to work on a Linux-based operating system (OS) can be downloaded at http://www.nipgr.res.in/nexcade_download?.html. In addition, we have developed NEXCADE as an OS-independent online web server freely available to the scientific community without any login requirement at http://www.nipgr.res.in/nexcade.html.
FOOD AND NUTRITION POLICIES IN AFRICA: CAPACITY CHALLENGES AND TRAINING OPTIONS
Suresh C. Babu
African Journal of Food, Agriculture, Nutrition and Development , 2001,
Abstract: In spite of the continued efforts of nutritionists to address nutrition problems in sub-Saharan Africa, the levels of undernutrition remain high. This paper is an attempt to provide an overview of the challenges that face nutrition planners and policymakers in implementing and evaluating nutrition policies and program interventions. Presenting a conceptual framework for analyzing the causes of nutritional outcomes, it reviews past experiences in implementing various nutrition policies and program interventions in sub-Saharan Africa. Identifying capacity gaps for designing nutrition policies and programs, it outlines strategies for increasing the nutrition policy capacity in Africa. It is argued that unless the profile of nutritionists is elevated through appropriate capacity strengthening, their role in influencing nutrition policies and programs and hence nutritional outcomes will remain low in Africa.

A. V. Suresh Babu, M. Shanker, V. Venkateshwar Rao
Advances in Remote Sensing (ARS) , 2012, DOI: 10.4236/ars.2012.11001
Abstract: Development of irrigation infrastructure and its efficient management is the primary concern for sustainable food production. The assessment of irrigation infrastructure creation, its utilization, diagnostic evaluation of the various performance indices (monitoring) are important to measure the efficiency. Benchmarking of Irrigation Systems (BIS) is for the diagnostic analysis of irrigation performance indicators comprising of Irrigation Infrastructure System (IIS), Agricultural System (AS), Water Delivery Dynamics (WDD). Since, the performance of an irrigation command varies with space and time, utilization of spatial information technologies viz. Remote Sensing (RS), Geographical Information Systems (GIS), Global Positioning Systems (GPS) useful to provide spatial information on several indices in the process of benchmarking (BM). Information requirements for BIS at different stages, utilization of spatial information technologies to derive irrigation performance indicators was discussed with suitable examples and demonstrated in this study. The studies carried out indicates that the geospatial approach for BIS enabled the improvements in data collection methods, diagnostic analysis, spatio-temporal visualisation of BM indicators at disaggregated canal level which would be useful for decision support during the corrective management measures. The conjunctive use of multi-date (medium resolution) satellite data, high spatial resolution data, field data on water deliveries was found to be an alternative to the conventional non-spatial approaches for BIS and thereby better water resources planning and management.
