Tourism is first about gathering information about a geographically located place and then travelling to it. The method of gathering information about a tourist place to visit is dependent on the means and technology available at that relevant time. Out of the various tools that are available for the purpose, the most powerful emerging tool is Geoinformatics: i.e. dynamic non spatial attribute information linked with spatial information. In the present case study, some of the capabilities of Geoinformatics are explored as applicable to tourism for a major pilgrim place Devghar, in Jharkhand State.Arc View GIS software, have been used to customize, keeping in mind, the various entities to be used for the particular study area useful for tourist information system of the place, after the generation of various thematic information. Though some database inventory was made using secondary data for the study, an additional information was collected first hand from the site. A lot more effort needs to be put up for collection of data upon which information could be made available to the tourists/pilgrims visiting Devghar. The present study has explored but a tip of the iceberg. The analysis and the result of the study gives web enabled solutions for the tourist related information.

Nowadays, in biomedical field, imaging techniques are used to discover the abnormalities in the particular region. Lesion is an area in an organ or tissue, which has suffered from damage through injury or disease, such as a wound, ulcer, abscess, or tumor. Lesion area of the tissue is detected using source images. Wireless capsule endoscopy image of the gastrointestinal tract is used to find the lesion. Preprocessing of image is done using denoising by multidimensional filter. Denoised image is edge detected during which the edge points in an image differentiation is highlighted by Sobel edge detection. The value of each pixel in the edge detected image is evaluated based on the comparison of corresponding pixel in the input image with its neighboring pixels by the morphological operation. Erosion and dilation operation erodes and adds pixels respectively to the edge detected image, so that the value of the output pixel has the maximum pixel value. During segmentation, the pixels are grouped using superpixel algorithm to reduce the complexity while maintaining high diagnostic accuracy. As a final point, the Correlation coefficient test finds the spoiled area between healthy tissue and abnormal tissue by color encoding. This intends to identify the suspected abnormal areas (lesion) from the source images.Keywords

Dairy industry contributes to the pollution of the environment, both in quality and quantity. It generates about 0.2 to 10 L of effluent per liter of milk processed. Up-flow anaerobic sludge blanket is most suitable for biodegradable wastes, hence the present study evaluated the performance of UASBR through a laboratory model (25 liters of volume) for treating the dairy effluent with maintained psychrophilic temperature (15-20°C) at phase I and mesophilic temperature (30-40°C) at phase II. This model was studied for its treatment efficiency in terms of COD reduction. In the phase I, the average varying influent COD applied over the model are 1684, 2693, 3160, 3637, and 4059 mg/L with flow rates for each average influent COD as 4.80, 9.60, 14.40, 19.20 and 24.00 L/d. It was found that, successful COD removal of 91.42% was for the operating conditions of OLR at 0.039 kg COD/kg VSS day, VLR at 0.70 kg COD/m3 day and HRT at 5.21 days. In the phase II the average varying influent COD of 2316, 2827, 3329, 3908 and 4522 mg/L were applied with same flow rates. The experimental work on UASBR model was found successful with 94.70% COD removal under the operating conditions of OLR at 0.037 kg COD/kg VSS day, VLR at 0.630 kg COD/m3 day and HRT at 5.21 days. The reactor achieved BOD, TSS, TDS, N and P removal efficiency, observed in phase I and II, as 91%, 82%, 89%, 42% and 46% and 96.4%, 86%, 91%, 41% and 50% respectively.Keywords

Therapeutic or experimental radiation exposure is known to impair testicular Leydig cell function. However, the molecular mechanisms that underlie such effects are largely unknown. Our previous study demonstrated that higher doses of gamma radiation impair basal and LH-stimulated cAMP production. The present study deals with the dose dependent effects of gamma radiation on LH and cAMP stimulated steroidogenesis in human Leydig cells. Testicles removed from advanced prostatic carcinoma patients, who do not have any endocrine or metabolic disorders known to affect the testicular functions were used in the present study. Prior to orchidectomy, serum hormones such as FSH, LH, testosterone and estradiol were assayed to evaluate the testicular functions.- Streptozotocin-Diabetes Impairs the Differentiation of Epididymis during Sexual Maturation

Male reproductive dysfunction is a common feature in diabetic boys and men. Defective spermatogenesis, sperm count, sperm motility, seminal fluid volume and serum testosterone, supports endocrine basis for impotence and fertility disorders. The present investigation was carried out to understand the impact of diabetes on the structure and development of epididymis during the critical period of sexual maturation in rats. Prepubertal (40 days old) and adult (120 days old) male Wistar rats were made diabetic by single injection of streptozotocin (120 mg/kg body weight for prepubertal and 65 mg/kg body weight for adult) intraperitoneally.- Serum Dihydrotestosterone is a Major Determinant of Bone Mineral Density in Men

In the present investigation, 100 osteoporotic men with 100 age-matched normal were studied for serum sex steroids, parathyroid hormone (PTH), thyroid hormone (T3), cytokines and bone turnover markers. Serum dihydrotestosterone (DHT) was significantly decreased in osteoporotic men compared with normal. In osteoporotic men, there was a significant increase in serum interleukin (IL)-lalpha. A marked increase in bone formation marker, serum osteocalcin (OCN) and bone resorption marker, serum tartrate-resistant acid phosphatase (TRAP) reflects high bone turnover in osteoporotic men. In conclusion, the present findings point out an important role of DHT in maintaining BMD in men. A strong positive correlation of serum DHT with BMD offers new perspectives in understanding the role of non-aromatizable androgen in the regulation of bone metabolism in men.Keywords

The present study was aimed at evaluating the effects of streptozotocin (STZ)-induced diabetes and insulin replacement on the androgen (AR) and estrogen receptor (ER) concentrations in the caput, corpus and cauda epididymides of prepubertal and adult Wistar rats. Prepubertal (40 days old) and adult (120 days old) male Wistar rats were made diabetic by single intraperitoneal (i.p.) injection of STZ (120 mg/kg and 60 mg/kg body weight, respectively). To one set of diabetic rats, insulin was administered daily at a dose of 3 U/100 g body weight, subcutaneously, in two equally divided doses at 8.00 AM and 6.00 PM. All the rats were killed on the 21st day of commencement of experimentation. The epididymis was dissected out and caput, corpus and cauda segments were separated, freed from spermatozoa and processed for AR and ER quantification. STZ-induced diabetes caused a marked decrease in both nuclear and cytosolic AR and ER concentrations in the caput, corpus and cauda epididymides. Insulin replacement circumvented the adverse effects of diabetes in a segment-specific manner. These findmgs emphasize the detrimental effects of diabetes and the importance of insulin in the maintenance of epididymal AR and ER concentrations in immature as well as adult rats.Keywords

Breast cancer is one of the major causes for the increase in mortality among women, especially in developed countries. Brea cancer is the second most common cancer in women. The presence of microcalcifications in breast tissue is one of the most important signs considered by radiologist for an early diagnosis of breast cancer, which is one of the most common forms of cancer among women. In this paper, detection of microcalcification is performed in two steps: preprocessing& enhancement, segmentation. First, the thresholding algorithm is applied for the breast boundary identification and a new proposed modified tracking algorithm is introduced for pectoral muscle determination in Mammograms. Second, the Genetic Algorithm (GA) and Artificial Bee Colony(ABC) is proposed to automatically detect the breast border and nipple position to identify the suspicious regions on digital mammograms based on asymmetries between left and right breast image. The basic idea of the asymmetry approach is corresponding left and right images are subtracted to extract the suspicious region. The algorithms are tested on 161 patient’s digitized mammograms from MIAS database. In general theproposed GA, ABC and Bilateral algorithms are quite competitive with the other algorithms.

The accumulation of macro- and micro-debris is a growing concern in the oceans and coastlines all over the world. However, the debris characteristics, accumulation and transport pathways along the Indian coastline remain poorly studied. Marine debris is not just an aesthetic problem; it poses a serious threat to marine organisms, ecosystems, human health and navigational safety. Despite the increased international attention, the build-up of these materials along the Indian coastline and coastal waters is poorly understood or reported. Since the debris problem is global, curbing the issue in our coasts is not a single-step process. Nevertheless, assessment and monitoring of this debris along the beaches, coastal waters and on the seabed is crucial for understanding the dynamics of debris movement and subsidence.Full Text

Background/Objectives: Water body management and food-grains supply will be challenging tasks. Selecting spectral bands for accurate area estimation of water body and selected vegetation (crop) is the objective of this study. Methods/ Statistical Analysis: Indices such as Normalized Difference Water Index (NDWI), Normalized Difference Vegetation Index (NDVI) are used for extracting water and vegetation respectively from other features. Generally bands providing high index values for the target are utilized for extraction. In this study the bands giving high index value for selected target and low index for surrounding are selected. Bands selected in this method provide better extraction and accurate area estimation. Findings: The NDWI and NDVI are based on multispectral data and have less number of combinations for band sets selection. Though the proposed method is derived from NDWI, it utilizes the Hyperspectral data that has narrow and hundreds of bands. Another advantage of this method is it utilizes the index value of target and surrounding features. It selects suitable band set by iteration method and provides accurate extraction of the targets and area estimation. The performance of the bands selected in this method was tested with coastal and inland water bodies. Area estimated with this method matches with NDVI and MNDWI values. Applications/Improvements: This method selects suitable bands to estimate area of water body and vegetation. This estimation will be useful for water body management and food production forecasting.Keywords

Objectives: The municipal solid waste management is a challenging task for local authorities. To manage this, a study was conducted in Kanchipuram municipality, Tamil Nadu, India. Methods/Statistical Analysis: Spatial database was prepared for the study area by using high-resolution satellite imagery. Non-spatial information like street name, road name, a nearby landmark, bin number and bin type were added in Geographical Information System (GIS). In this study modern technique like Global Positioning System (GPS), a communication system (GPRS and GSM), GIS and computer programming are integrated to assist the solid waste management. Findings: This integration may serve to overcome the conventional conflict in solid waste management within the municipal region. The proposed system consists multiple spatial information in the prepared digital database, like bin location (with reference to its latitude and longitude); ward details, onboard monitoring of bin strategy. Based on a study of smart bin usage in developed countries, new type smart bins with sensor arrangements are suggested. The solid waste strategy of each bin in each ward could be collected by monitoring authority through the GPRS and GSM technique which is fixed in the proposed bin. This developed system consists of the bin priority, strategy, and track location. This will serve for taking a decision by applying queries to the created database and also to enhance the solid waste management technique in Kanchipuram municipality. Application: This work proves incorporation of recent technique in municipal solid waste management will save both time and money.Keywords

We propose a solution for automatic co-registration of LISS-4 MX radiometrically conditioned multi-spectral images issue by considering an optimization problem in which mutual information-based approach is used. Co-registration of multi-spectral images from the same sensor may also be a tough problem to tackle, whenthe payload imaging geometry is complex. The multi-spectral images acquired by ISRO Resources at-1/2 LISS-4 MX class of sensors pose such problems and demand an automatic registration solution for system corrected product generation to cater to user needs. Optical remote sensing image registration is assisted by image geo-referencing or navigation information along with components such as feature detection, matching, correspondence, and resampling the input image to the reference geometry. Intensity-based methods employ an iterative registration framework,where similarity metric based image matching and correspondence is refined to find out optimum transform parameters. We could successfully employ mutual information-based adaptive stochastic gradient descent optimization algorithm to do sub-pixel level satellite image registration tasks by a careful choice of parameters and models related to metric, transform, optimizer, and interpolator in a robust image registration framework which is automatic for different terrain data. The performance is also compared to a recent scale invariant feature transform (SIFT)-based registration method.Keywords

This work is concerned with application of simple, accurate, precise and highly selective reverse phase high performance liquid chromatographic (RP-HPLC) method for simultaneous estimation of Tramadol HCl and Paracetamol in combined dosage form. Chromatographic separation was achieved isocratically at room temperature on phenomenex C18 column (250×4.6 mm) with a mobile phase composed of 5% Tri-fluoroaceticacid in water:Acetonitrile:Methanol in the ratio of 70:20:10% v/v/v at flow rate of 1.0 ml/min. Detection is carried out using a UV detector at 254 nm. The retention time of Tramadol HCl and Paracetamol was found to be 3.890±0.5 min and 1.990±0.5 min respectively. The method was found to be linear in the range of 0.1-10 μg/ml with mean recovery of 98.96% for Tramadol HCl and 99.11% for Paracetamol. The correlation coefficients for all components are close to 1. The developed method was validated according to ICH guidelines and values of accuracy, precision and other statistical analysis were found to be in good accordance with the prescribed values. Thus the proposed method was successfully applied for simultaneous determination of Tramadol HCl and Paracetamol in routine analysis.Keywords

Salinity has deleterious effects on many crops, especially in morphology of the plants. A research was conducted to study the effect of salinity on tomato genotypes (PKM 1 and TNAU THCO 3) and alleviation by using plant growth regulators (PGRs) and nutrients in the Department of Crop Physiology, TNAU, Coimbatore. Salinity was imposed by using NaCl at 100 mM concentration. The responses of two tomato genotypes under salinity were studied. Among two genotypes, PKM 1 was affected more by salinity than TNAU THCO 3. Foliar application of plant growth regulators like brassinolide (0.5 ppm), salicylic acid (100 ppm), benzyl amino purine (50 ppm), ascorbic acid (100 ppm), glutathione (50 ppm), KNO3 (0.5%) + FeSO4 (0.3%) + Borax (0.2%) and nutrient PGR concoction (K2SO4 (0.5%) + CaSO4 (0.5%) + Borax (0.2%) + NAA (20 ppm) were carried out at 20 and 40 DAT. Significant variations and adaptability among stressed and non-stressed plants were observed in both the genotypes. The study revealed that, among the treatments, brassinolide showed the premier observations like plant height (73.40 cm), ischolar_main length (18.60 cm), ischolar_main volume (133.25 cc), leaf area (1275.54 cm2) and total dry matter production (TDMP) (88.42 g plant-1) followed by salicylic acid when compared to control. Among the two genotypes used in this study, TNAU THCO 3 responded better for the application plant growth regulators and nutrients than PKM 1 under salinity.Keywords

Information-oriented intensity-based cost functions are generally used for optimization frameworks in automatic satellite image registration. Optimization mechanics which updates the transform parameters in the iterative loop requires estimation of derivatives of the cost function to set-up update rules that retrieve the deformation model between the image pairs. Application of stochastic approximation of cost function and its derivatives for solving optimization problems while the objective function is non-differentiable or non-smooth or computed with noise is encountered in real-world problems. The known methods of approximation for solving these problems use the idea of stochastic gradient and certain rules of changing the step length for ensuring convergence. In this article, satellite image coregistration problem is chosen for comparing the performance of two important stochastic optimizers like adaptive stochastic gradient descent and simultaneous perturbation stochastic approximation. Coregistration datasets from Resourcesat-2 LISS-4 MX sensor are chosen for different terrains and features to study subpixel accuracies of order better than 1/20th of a pixel achieved in the comparison of two different optimization techniques employed in intensity-based automatic image registration framework.Keywords
