Abstract

Numerical classification of 8 forest soils belonging to orders Entisol, Inceptisol and Mollisol of Bhabar region of Nainital District in Uttar Pradesh was done. The taxonomic structure worked out using dissimilarity coefficients was presented using the clustering technique of Unweighted Pair Group Method using Arithmetic averages (UPGMA). The grouping of soils on the basis of numerical classification is in general, in conformity with their classification according to USDA Taxonomy. Departures from this general observation suggest a re-examination of existing taxonomic classification.

Abstract

The Saline and Alkaline soils cover nearly 7 million ha of land occurring in as many as 14 states of India. It is indeed a challenging task to afforest these aresS since most of the indigenous and exotic species are not tolerant of soil alkalinity and salinity. Eucalyptus plantation programme has gained momentum during the recenl past under social forestry and farm forestry programmes. Eucalyptus are easy to propagate and require little care. Their rate of growth and biomass production is high and has attracted the attention of foresters as well as the general public. Barren lands have been considered best for planting fast growing adaptable exotic and indigenous spedes. Many Eucalyptus species and their salt resistant provenance may be of utmost importance for afforesting the salt affected and alkalinity affected soils in various regions in India. More genetical reseach is essential to locate suitable provenances to plant them in these salt and alkall affected areas. Eucalyptus species growing in the homoclimatic zones in Australia under saline and alkaline soils may prove of great help in successCully afforesting such tracts in various regions of India. The climatic, ecotypic and soil conditions of the environment where there species or their strains occur in Australia needs thorough study. Studies are also required to discover and locate identical locations in India for trying these species and strain of Eucalyplus. Eucalyptus comoldurensis is a potential species for this purpose and its new provenances and strains need exploratory research. It is advisable that under seed exchange programme more stress should be laid on procuring seeds of such available provenances of E. camaldulensis which occur in saine and alkaline solis in Australia. Inter specific hybridization for evolving salt and alkali resistant strains of Eucalyptus is expected to case the problem of afforestation in saline and alkaline solis.

Abstract

Soils and land use pattern were studied ia a part of Nainital Tarai and Bhabar Forest, Uttar Pradesh. The objectives of the study were to examine feasibility of using aerial photographs as base map for delineating soli boundaries and land use patterns, to characterise and classify the soils and to study their genisis. Reliable stereoscopic interpretation of aerial photographs for accurately delineating soil boundaries could be possible only for the areas which were either under cultivation or under new plantation. In remaining area under thick forest and grass vegetation only random field checks for studying morphological properties of soils were made. The boundaries of existing land use pattern could be easily delineated on aerial photographs and were correlated by field checks. Three distinct soil series namely, Baurkbatta, Dauli and Lalkuan were identified in the whole area but their mapping could be done only for area under cultivation. Characteristics, clasiffication and genesis of tbese series were studied. Baurkhatta series was a coarse loamy, mixed, hyperthermic Aquic Hapludoll. Daull was coarse loamy, mixed, hyperthermic. Mollie Aeric Hapiaquept and Laikuan was a loamy skeletal, mixed, hyperthermic Typic Eutrochrept. The local topography and to some extent kind of vegetation were the factors determining soli genesis. Of the total mapped area (1313.12 ha). Baurkhatta, Daull and Lalkuan series occupied 33.4,43.9 and 22.7 per cent, respectively. Of the major land uses, about 43 per cent area was under forests in which Eucalyptus, Sal and Sisam were the main tree species; 3.5 per cent area was under grassland where johnson, tiger and kamal were the main grasses; about 11 per cent area was under river bed and roads and rest 9.5 per cent was under cultivation where new plantation was being planned. Soils under the influence of grass vegetation had thicker, darker and higher base status horizons than those of soils under forest vegetation.

Abstract

Majority of the world's human population, especially in developing countries, depends on traditional medicine based on medicinal and aromatic plants (MAPs). Relatively few MAP species are cultivated. The great majority is still provided by collection from the wild. This trend is likely to continue over the long term due to numerous factors. Cultivation is not necessarily the most beneficial production system. Wild collection practices secure valuable income for many rural households, especially in developing countries. However, over-exploitation of MAPs, has been resulting in the loss of habitat and reduction in the regeneration of the MAP species. For these reasons, approaches to wild MAPs collection that balance the needs of local, regional, and international markets with the need for conservation and sustainable use are urgently needed. The present study was undertaken to develop safe harvesting limits for Andrographis paniculata Nees., Evolvulus alsinoides Linn., Phyllanthus urinaria Linn. and Rauvolfia serpentina Benth. occurring naturally in Sal forests of the Doon valley. Negative linear relationship was observed to exist between regeneration rate and harvesting intensity in all the four plant species at all the three sites. Threshold level of harvest adversely affected the regeneration of the above species.

Abstract

The quantitative data such as satellite derived winds are useful for improvement of the numerical prediction of weather events like tropical cyclones. In this study, the satellite derived winds from QuikSCAT surface observations and KALPANA-1 atmospheric motion vectors are used during the cyclone PHYAN in order to update the initial and boundary conditions through three-dimensional variational assimilation technique within the Weather Research Forecasting (WRF) modeling system. The simulated mean sea level pressure and 850 hPa wind fields from eight experiments are presented in this study in order to analyze the observed and simulated features of the tropical cyclone PHYAN that occurred in the month of November, 2009. The model results are also compared with the KALPANA-1 images and the India Meteorological Department (IMD) predicted results. Further, the intensity and track of the cyclonic storm PHYAN, generated from the simulations are also compared with the IMD predictions in order to evaluate the model performance.

Abstract

The number of active web pages increases exponentially. According to the survey, the web has 14.3 trillion active web pages. The problem faced by present search engines is difficulty in returning relevant information. The current search engines do not perform semantic search and are not capable to return results based on user's perception. In this paper a perception based search engine is proposed that returns results as per the user point of view. To achieve semantic searching, a knowledge base is constructed which stores knowledge in the form of predicates. To extract knowledge from knowledge base, decision theory is used that does not restrict to any specific domain.

Abstract

An arcuate belt of Precambrian vo1cano-sedimentaries, designated as the Hindoli Group, is sandwiched between the cratonic Archaean Banded Gneissic Complex terrain and the platformal Vindhyan sediments. Turbidites of mainly quartz wacke and petites with interlayered lava flows and tuffs of basalt, basaltic andesite and daciterhyodacite composition constitute the bulk of the Hindoli vo1cano~sedimentaries. These are interpreted to have been deposited in a continent-marginal basin with active participation of an arc system. Toward the end of the basin evolutioo; the continent-margin acted passively when quartzarenite and carbonates were deposited in a stable shelf regime.

Abstract

The Naini lake is a product of rotational movernent on a NW-SE trending Nainital Fault, quite after the establishment of the drainage of a mature stream named Balia Nala. Detailed bathymetric study, permits division of this crescent-shaped lake into two subbasins separated by an approximately 100 m wide transverse underwater ridge, 7m to 20m below the lake surface. The southeastern and northwestern parts, 11 to 25 m and 4 to 27 m deep, respectively, are filled with unconsolidated sediments, 15 m thick on an average. The semiconsolidated sedimentary layers locally exhibit slumping an slopes and deformation in channel beds. These features together with thetransverse Central Ridge, the deep channel cutting through it, the small scarps and terraces or step-like features on the slopes of the narrow V-shaped undemater valley in the southeastern part and its thick filling in parts due to blockade resulting presumably from fault movements, and the existence of deformed and displaced acoustic reflectors are interpreted as indicating quite recent movements along the Nainital Fault. Hitherto unidentified pinnacle-like objects penetrating through or perched atop sediments, are suggestive of either tectonic displacement and squeezing or of the hazard of mass movements which have occurred. A number of small but rapidly growing deltas along shores indicate accelerated pace of sediment input, resulting from quickened erosion in the catchment area.

Abstract

This article describes the possibility of using the fast image analysis technique for qualitative and quantitative analysis of equatorial plasma bubble obtained using All-Sky imager (ASI) data. Automated image processing (generally) is useful for identification of equatorial plasma bubbles (EPBs) and its parameters. We have developed a fast (and efficient) analysis technique essential to study the data of images. The present work reports the results of a statistical study of the zonal plasma bubble velocities using nightglow OI 630.0 nm emission data, acquired by ASI (FOV 140°) at the low-latitude station Kolhapur (16.42°N, 74.2°E and 10.6°N dip lat.). Based on the observations of 15 nights made in January 2012, we have determined the velocity of EPB using our new method. The daily mean values of the EPB velocity match well with those of the earlier studies made at Kolhapur. We have found that, generally, the mean zonal drift velocities of the plasma bubbles tend to decrease with local time (after midnight). The most significant finding from this work is that the calculated velocities of plasma bubble using fast and scanning methods are nearly equal.

Abstract

The photometric measurements of mesospheric OH and O(¹S) emission, carried out from Kolhapur (16.8°N, 74.2°E), Maharashtra during January-April 2005 are used to study the wave characteristics. The nocturnal variability reveals the dominant long-period wave signatures with significant amplitudes of embedded short-period waves. We carry out a sensitivity study on the vertical wavelength (VW) derived with the help of Krassovsky parameters (η = |η|e^iΦ) of the OH data, which reveals VW to vary from 38.9 to 110.2 km. This was compared with the VW estimates using the phase difference of the simultaneously observed waves in both OH and O(¹S) emission intensities. Results reveal that in the absence of attitudinally resolved measurements, the VW estimated using Krassovsky method can be used.

Abstract

Due to exponential growth and application of networks in current scenario network reliability has become most essential aspect of network management. Facilitating the users with services is not alone sufficient to satisfy the users but their dependency on networks must also be sustained by providing reliable network. Conventional approaches to address network management or particularly fault management are SNMP or CMIP based systems. These systems are based on request response concept and involve a huge amount of data to be transmitted over network links. These approaches suffer from scalability and flexibility. Mobile agents open a hopeful door to deal with shortcomings of conventional approaches. A lot more sensible efforts have been made towards the improvement of fault management process in context of scalability, flexibility, bandwidth utilization and response time. This paper is mainly focused on exploring the work done by researchers to address problems in conventional fault management strategies.

Abstract

The exponential rate at which volume of data is increasing, it is actually impractical to avoid the need of analyzing data for decision-making purposes. Clustering is one of the very effective ways for the data analysis. It is a principal tool of data mining for extracting previously unknown patterns existing in spatial datasets. It is a process of gathering similar data objects into one group such that objects in different groups are dissimilar. Datasets having non-uniform data object distribution are not dealt properly by the available clustering algorithms in literature. In this paper, an innovative approach of generating clusters in spatial datasets (uniform or non-uniform) have been proposed which models dataset using Delaunay structure for capturing spatial proximities and the analysis of the Delaunay edges have been carried out based on a range which is computed automatically by the algorithm for determining whether the two vertices are attracted towards each other or there is a repulsion between them. The edges corresponding to the vertices that are repulsive to each other are removed from the Delaunay structure thus obtaining the desired clusters of arbitrary shapes without any human interaction. The edges are classified as very strong edges, weak edges and floating edges. The dense and sparse clusters present in the same dataset have also been identified effectively even in the presence of bridges between the two clusters. The experimental study is conducted on sample datasets, which shows encouraging results.

Abstract

During the storage of cereal grains and their flours, titrable acidity of their lipid extracts increases and the grains undergo a deterioration in quality. Changes in titrable acidity of lipid extracts during storage of various cereal grains have been studied by several workers. India has now become self-sufficient in wheat, with the introduction of several high yielding, disease resistant varieties with better nutritional qualities. FCI is the chief agency, concerned with the surplus storage of wheat and its distribution. Wheat during storage is likely to undergo deterioration in quality. Very little work has been reported regarding these changes in grains and wholemeals of Indian wheat varieties during storage. The present study was therefore undertaken to find out the changes in fat acidity values of grains/whole meals over a period of eight months of storage using different storage conditions.

Abstract

The effluent discharged from distillery industries has shown higher values of physico-chemical parameters in the study area. The values of temperature, pH, TS, TDS, TSS, DO, BOD, COD, chloride and potassium were found to be increased in the River Narmada at the study point II to VI in comparison to the study point I taken as control. This showed that the entry of distillery effluents altered limnochemistry of River Narmada in the study area, which may put an adverse effect on the aquatic life.

Abstract

An experiment was conducted to evaluate the efficacy of a consortia formulation of Pseudomonas fluorescens and Trichoderma harzianum for management of bacterial wilt disease of ginger in Assam. Inhibitory effect of the biocontrol agents was evaluated in vitro following dual culture assay method for their efficacy against Ralstonia solanacearum, the ginger wilt pathogen. Quantitative assay of population dynamics of the two antagonists, mass cultured in organic substrates viz., vermicompost (VC) and mustard oil cake (MOC) revealed that the antagonists maintained a high population count up to 120 days of storage at room temperature. Pseudomonas fluorescens recorded highest average population (45.47 x 10⁷cfu/g) when mass cultured in the mixture of VC and MOC, while T. harzianum recorded maximum average population (34.14 x 10⁷cfu/g) when mass cultured in MOC. Bioformulations were further evaluated for their efficacy in ginger wilt management under field condition. Efficacy of one fungicide (Copper oxychloride) and an antibiotic (Streptocycline) was also tested for comparison. Lowest disease incidence (15.63%) was recorded in the treatment of seed treatment (ST) and soil application (SA) of P. fluorescens and T. harzianum consortia mass cultured in the mixture of VC and MOC. It was followed by ST and SA of T. harzianum mass cultured in MOC (21.88%), which was statistically at par with the application of copper oxychloride (26.25%).

Abstract

Manganese (Mn) is one of the most abundant metals in Earth's crust. Manganese is present in ground water as a divalent ion (Mn²⁺) and is considered a pollutant mainly because of its organoleptic properties. It is an essential metal for the human system and many enzymes are activated by manganese. Therefore, manganese has to be removed from some waters and wastewaters for various reasons. Conventional chemical and physical treatments for Mn (II) removal from contaminated effluent consist of precipitation, depth filtration, ion exchange, adsorption and oxidation. The adsorption technique has been found to be one of the most effective for the removal of metal ions from solution. This review focuses on preparation of adsorbent by using of low cost material to remove manganese from wastewater.

Abstract

Background/Objectives: Provide better search results and improve overall search experience of the users while searching information over the Internet. Most of the commonly used search engines today utilize link structure based page ranking for ordering of web pages and give no consideration to web page’s relevance and user-feedback etc. and suffer from topic-drift problem. As a result users seldom find accurate, precise and desired information on first page of the result-set. The users have to scan through the large result-set refining it manually which adversely affects the overall search experience of the user. Therefore there is a need to provide better ranking solutions. Methods/ Statistical Analysis: The methodology used for ranking a web page in the proposed algorithm includes ranking based on web page characteristics, user explicit feedback and preferences. The algorithm computes page rank of a web page based on number of times of occurrence of user specified Keyword on the web page, web page’s priority, its rating and popularity as specified by user feedback The algorithms also attempts to match user preferences in terms of domain and type of information of the web page user are interested in for page ranking. Findings: The proposed algorithm promises to provide best web pages in conjunction with user needs and interest, thereby improving the overall quality of the search results and user satisfaction. Application: The proposed algorithm can be used in Search Engines to provide better user specific results.

Abstract

Densities and speed of sound were measured for the binary liquid mixtures formed by Chlorobenzene with Benzene at 298.15, 303.15, 308.15 and 313.15 K and atmospheric pressure over the whole concentration range. Prigogine-Flory-Patterson model (PFP), Ramaswamy and Anbananthan (RS) model and model suggested by Glinski, were utilized to predict the associational behavior of weakly interacting liquids. The measured properties were fitted to Redlich-Kister polynomial relation to estimate the binary coefficients and standard errors. An attempt has also been made to study the molecular interactions involved in the liquid mixture from observed data. Furthermore, McAllister multi body interaction model was also used to correlate the binary properties. These non-associated and associated models were compared and tested for different systems showing that the associated process yield fair agreement between theory and experiment as compared to non-associated process.

Abstract

The empirical relation due to Auerbach for evaluating surface tension with the help of ultrasonic velocity and density has been modified by introducing temperature as an additional parameter. The new equation has been shown to be better than the original equation. The modified equation has been applied to obtain precise values of surface tension of five ternary liquid systems [Chlorobanzene (1)+cyclohexane (2)+n-heptane (3), Chlorobenzene (1)+cyclohexane (2)+n-hexadecane (3), Chlorobenzene (1)+cyclohexane (2)+isooctane (3), Chlorobenzene (1)+isooctane (2)+n-heptane (3), 1-chloronaphthalene (1)+isooctane (2)+n-heptane (3)]. These values are then compared with the values obtained by applying different approaches including: Altenberg (AL), Mc-Gowan (McG), Sanchez (SZ), Goldsach and Sarvas (GS) and Flory theory (FT). The results have been presented in terms of their average percentage deviation (APD) values and comparative studies have been done. An attempt has also been made to explain the nature of molecular interactions and force involved in these mixtures.

Abstract

Aim: The aim of the present study was to investigate the molecular etiopathology of occurrence of reproductive diseases in female goats. Reproductive diseases in goats account for major economic losses to goat farmers in terms of valuable loss of offspring and animal productivity.
Materials and Methods: A total of 660 female genitalia were examined for pathological conditions (macroscopic and microscopic lesions). The etiopathological study was carried out for the presence of pathogenic organisms such as Brucella, Chlamydia, and Campylobacter in the uterus and ovary. Based on the microscopic lesions, suspected samples were subjected to diagnostic polymerase chain reaction (PCR) for various etiological agents employing 16srRNA genus specific primers for Campylobacter and Chlamydophila and OMP31 gene-based PCR for Brucella melitensis and nested PCR using ITS-1 gene primers for Toxoplasma gondii. For Brucella suspected samples, immunohistochemistry (IHC) was also performed.
Results: In studied female genitalia, 108 (16.30%) showed gross abnormalities with overall 23.32% occurrence of pathological conditions (macroscopic and microscopic lesions). Pathological involvement of the uterus was the highest 68 (62.96%), followed by the ovaries 27 (25%) and other organs. Major uterine condition observed was endometritis (5.60%). In uterine infections, 35 (5.30%) samples were found positive for Campylobacter spp., 12 (1.81%) samples for B. melitensis, and 3 (0.45%) samples were positive for Chlamydophila spp. Among the samples positive for B. melitensis by PCR, 3 were found positive by IHC also. Corynebacterium ovis was detected by PCR using specific primers in a case of hydrosalpinx. It was concluded that many pathological lesions in female genitalia of functional significance play a major role in infertility in goats.
Conclusion: The present study concluded that many pathological lesions in female genitalia of functional significance play a major role in infertility in goats.

Abstract

Weed management is an ever-present challenge to crop production. Presence of weeds in general reduces crop yield by 31.5 per cent (22.7 % in Rabi season and 36.5 per cent in Kharif and summer season). Yield losses due to weeds were about 65 per cent depending on the crop, degree of weed infestation, weed species and management practices. Presently available weeder mostly run by tractor or power tiller, these are large in size, cannot work for low inter row spaced crops.To over come these problems, portable knapsack power weeder was developed for low inter row spaced crops with width of cut was 25 cm. The main working components of power weeder were flexible drive shaft, worm gear box, rotor shaft, flanges and blades. The” L” type blade was selected having length, width and thickness of 130 mm, 30 mm and 5 mm, respectively, operating with a rotor shaft of 20 mm in diameter. Maize and chilli was tested with number of blades per flange (2, 4 and 6).

Abstract

Extensive erosion of high tidal mudflat along the northern parts of Gulf of Khambhat (GoK) was observed from the analysis of time series satellite images during the time period from March 2014 to September 2017. Around 28.66 sq. km area of high tidal mudflat eroded within this time period. Maximum erosion rates estimated have even peaked to about 4 km/year showing the severity of erosion. The mudflats under erosion are along the outer boundary of a meandering tidal channel connecting the Gulf with Mahi river. A possible cause of the incessant erosion of mudflats is the strong tidal currents along the outer boundary of the meandering tidal channel, that have carved the mudflats and pushed the tidal channel further landward. A subtle seasonal pattern of erosion was observed with decrease in erosion rates during the summer monsoon period when the high tidal currents are weak due to the river influx. Rapid erosion of the tidal mudflats has not only destroyed the vital habitat, but has also eventually exposed the inhabited land area to tidal flooding, making it vulnerable to erosion. The study shows the importance of assessing the stability of mudflats along the GoK, where large development activities are proposed.

Abstract

Background: Citrinin (mycotoxin) and endosulfan (pesticide) both environmental contaminants easily enter the food chain and are caoomon causes of various toxicities. Materials and Methods: In the present investigation, citrinin (CIT) (10 mg/kg feed) and endosulfan (1 mg/kg body weight) were administered orally alone and in combination to pregnant Wistar rats from gestational day 6 to 20 to study their effect to cause apoptosis in the pregnant Wistar rats and their fetuses. Apoptosis was assessed in dams by agarose gel electrophoresis, flow cytometry and electron microscopy, while in the fetuses it was assessed by flow cytometry only. Result: Citrinin and endosulfan in the combination group caused apoptosis in an additive manner as there was increased number of apoptotic cells as compared to the individual toxin and control groups. The fetuses also showed increased number of apoptotic cells in the combination groups, which also indicated that both the toxins crossed the placental barrier. Conclusion: So it was concluded that apoptosis played a significant role in the pathogenesis of endosulfan and citrinin toxicity.

Abstract

India is a vast country having agriculture sector as the backbone of its economy. A weed is essentially any plant which grows where it is unwanted or not required. A weed can be thought of as any plant growing in the wrong place at the wrong time and doing more harm to the farmer income. Several weeders are available which run by tractor or power tiller, these are large in size can not work for low inter row spaced crops. The portable knapsack power weeder is evaluated two different crops such as maize and chilliwith each blade (2, 4 and 6 blades per flange) combination. During the evaluation field capacity, field efficiency, weeding efficiency, plant damage, fuel consumption, performance index were evaluated. Actual field capacity of weeder for maize and chillicrop with 6 blades was 0.023 ha/hand 0.025 ha/h. Field efficiency of weeder for maize and chilli crop was 61.3 per cent and 66. 6.Weeding efficiency for maize and chilli crop was 89.3 per cent and 85.2 per cent. Plant damage for maize and chillicrop was 2.4 per cent and 3.30 per cent.

Abstract

The quality of raisins is mainly perceived by their colour. Green-coloured raisins are considered as the best quality raisins whereas brown/dark-coloured raisins possess poor quality. Raisin colour is affected by different factors like grape variety, pre-treatments to grape berries, drying method, drying conditions, etc. The present study was conducted to produce greencoloured raisins through two different treatments of ascorbic acid – dipping and spraying. These treatments were applied to Thompson Seedless grapes independently with different doses (100–500 ppm) of ascorbic acid. Results indicated that lesser darkening of raisins was observed when ascorbic acid was sprayed on bunches during drying than the dipping treatment. In all the samples, polyphenol oxidase (PPO) activity decreased with drying duration. Lower PPO content was noted in dipped and sprayed grapes than control. However, application of ascorbic acid influenced the other parameters. The present study revealed that ascorbic acid spray is suitable for retaining green colour in raisins with faster drying. Overall, 200 ppm ascorbic acid spray was found appropriate in the production of green raisins.

Abstract

In this article, we discuss the potential of airborne hyperspectral data in mapping host rocks of mineral deposits and surface signatures of mineralization using AVIRIS-NG data of a few important geological provinces in India. We present the initial results from the study sites covering parts of northwest India, as well as the Sittampundi Layered Complex (SLC) of Tamil Nadu and the Wajrakarur Kimberlite Field (WKF) of Andhra Pradesh from southern India. Modified spectral summary parameters, originally designed for MRO-CRISM data analysis, have been implemented on AVIRIS-NG mosaic of Jahazpur, Rajasthan for the automatic detection of phyllosilicates, carbonates and Fe–Mg-silicates. Spectral analysis over Ambaji and the surrounding areas indicates the presence of calcite across much of the study area with kaolinite occurring as well in the north and east of the study area. The deepest absorption features at around 2.20 and 2.32 μm and integrated band depth were used to identify and map the spatial distribution of phyllosilicates and carbonates. Suitable thresholds of band depths were applied to map prospective zones for marble exploration. The data over SLC showed potential of AVIRIS-NG hyperspectral data in detecting mafic cumulates and chromitites. We also have demonstrated the potential of AVIRIS-NG data in detecting kimberlite pipe exposures in parts of WKF.
