Culms representing before, during and after flowering phases were subjected to testing for certain strength properties in round and split forms. Round bamboo showed higher values in compression parallel to grain in culms before flowering phase, while static bending values were higher in culms during flowering phase. In split bamboo, strength properties (maximum crushing strength and static bending) were more in culms of after flowering (air-dry) phase than before and during flowering phase (green).Keywords

Leonotis nepetaefolia R. Br. (Laminaceae) is an attractive, symmetrical, annual medicinal plant. A brief description of the plant is described in the present article. The plant is believed to be a native of Africa and the distribution extends to tropical Asia and America. It has been cultivated in Brazil since long. The plant seems to have naturalized in India. Traditionally, the leaf is used in rheumatic affections and also serves as a tonic. Flower heads are used against scalds, burns, ringworm, and some skin diseases. Crushed ischolar_main is applied locally for facilitating breast milk to a mother after childbirth. Seeds are used in fever. It has also got the anticancer, antioxidant and antibacterial properties. In India, it grows wild but not common. In recent years, India has given due attention on this plant to develop it's agrotechniques for commercial cultivation. Accordingly, responsibilities were entrusted with the NBPGR Regional Station, Shillong since 1999.- Synchronisation of Flowering Periods Between Moghania macrophylla (Willd) O.Ktze and M. chappar Kuntze

Besides traditional propagation and breeding practices modernized methods of plant tissue culture is considered as a crucial factor for lac host plant improvement programme. Therefore, under the current study plant parts like seed cotyledons and axillary buds of lac host plants were cultured under different auxin (2,4-D) concentrations to find their ability to produce callus. Mostly in all cases,2,4-D concentrations of 4-10 ppm resulted in maximum callus development. The results open up the possibility of improvement in lac host plant through biotechnology. However, further studies for organogenesis and regeneration into complete plantlets are required with utmost importance.- Record of Flemingia stricta as a Lac Host

A Field experiment was conducted at the Indian Lac Research Institute, Namkum, Ranchi duriog 1988 and 1989. The growth analysis results revealed that various parameters had more values in first phase of 60-90 days after sowing (DAS) than advanced stage of the seedling growth (90.105 DAS). Relative growth rate (RGR). Crop growth rate (CGR) and net assimilation rate (NAR) were significantly affected by different date of sowiog in nursery during both the years except in the year 1988 at 90-105 DAS. However, variation in date of sowing did not affect LAR at different periods. The result indicated the need to adopt better management practices at early growth stages for better growth and development.- Air Layering in Galwang (Albizia lucida Benth.) a Lac Host Plant

This paper provides an in depth discussion on the titanium dioxide photocatalysis for the treatment of pulp and paper industry wastewater. The mechanism behind TiO2 photocatalysis, various reaction variables and application of TiO2 photocatalysis for the remediation of pulp and paper mill wastewater are discussed. TiO2 photocatalysis can cause rapid and complete degradation of nearly all electron rich organic compounds. It involves in situ generation of very reactive non-selective oxidizing species i.e. OH- radicals. Some laboratory experiments were performed to study the effect of catalyst dose and reaction time on the photodegradation efficiency. Paper mill wastewater was treated with UV/TiO2 process at pH 7 in a slurry type of reactor under artificial UV light. The catalyst dose (0.25 to 1.50 g/L) and reaction time (0.50 to 8.0 h) were varied for studying their effect on the degradation efficiency. The degradation efficiency was measured in terms of percent reduction in COD and colour of the wastewater. Up to 0.75 g/L of TiO2 the degradation efficiency increased but beyond this it decreased. The degradation rate during the first hour of treatment was very fast. After 4 h of treatment the degradation efficiency became more or less constant and there was no significant increase. The optimum results were obtained at a TiO2 dose of 0.75 g/L and reaction time of 4 h.Keywords

The study was under taken in Jodhpur district of Rajasthan. The district was selected purposively, as production under cumin crop was maximum in this district. Secondary data were used to compute the correlation co-efficient between arrivals and prices. Monthly data on arrivals and prices were taken for the period 2005-06 to 2009-10. It was noted that 63 per cent cumin produce arrived in the first quarter (March-May) of the year. The arrivals were 17.93, 8.54 and 10.02 per cent in the second, third and fourth quarters, respectively. Farmers got 10.36 per cent higher price by selling cumin in the second quarter over the post harvest season (peak season or first quarter). Sale of cumin in the third and fourth quarters of the year was not found advantageous. The correlation co-efficient between monthly wholesale prices and arrivals of cumin in the corresponding months and in the subsequent months were -0.578 and -0.588, showing that there existed inverse relationship between the two. The value of correlation co-efficient was estimated to be higher for the subsequent months than for the corresponding months. The value of correlation co-efficient between yearly arrivals and prices of cumin were negative in four years and positive only in one year out of the five years study period. This indicated that prices of cumin were not only affected by arrivals, but were also affected by factors such as demand, export-potential and seasonality of the crop.Keywords

An experiment on rearing of common carp was carried out in three types of ponds viz. earthen pond, cemented tank and poly tank at field centre, DCFR, Champawat (Uttarakhand) and at selected farmers field of Champawat District to evaluate the growth performance of this fish species. ANCOVA results revealed that there are three distinct seasons which influence on length-weight relationship of common carp culture in these pond systems. The fish follows isometric growth in spring season (March-May); (however it does not follow in the remaining seasons). Further, there is no specific growth pattern of common carp observed in these pond environment. Logistic curve is the best fitted model to the dataset obtained from cemented pond. However, Richards and von-Bertalanffy curves are found appropriate to represent the growth pattern of this fish in earthen and poly tank, respectively. In the long run, higher growth of fish is predicted in poly tank.Keywords

The authors favour the placement of Palaeocene-Eocene boundary at the Pseudohastigerina wilcoxensis datum. In the Cauvery basin subsurface, seemingly continuous late Palaeocene-Early Eocene successions are known only in the basinal depressions, which have been exemplified by the Chidambaram well data. Unless the sequences are well represented by cores, problems arise in delineation of Palaeocene-Eocene boundary in the flanks of ridges/highs in Cauvery basin as the index Palaeocene planktonic foraminifera are sometimes found reworked in the Eocene zones.
The occurrence of Nummulites, whose earliest occurrence is lately being attributed to the basal Eocene in the European basins, in the Cauvery basin Palaeocene corresponding to the Globorotalia velascoensis and Globorotalia pseudomenardii Zones - has been stressed. Further research is necessary in order to establish the evolutionary appearance level of these camerinids in the Indian subcontinent.

Effectiveness of hermetic storage in combination with botanical Ageratum conyzoides for the control of post harvest pests of maize Sitophilus oryzae (L.) and Sitotroga cerealella (Oliv.) was evaluated under artificial infestation by different packing materials. It was observed that High density polythene (HDPE) bag and Double Layered Polythene (DLP) bag with A. conyzoides are most effective in controlling S. oryzae and S. cerealella. The number of F1 progeny of S. oryzae and S. cerealella emerged in treatments ranged from 7.75 to 21.70 and 8.70 to 25.50, respectively with each mean being significantly different from each other. Both HDPE and DLP bag in combination with A. conyzoides recorded lowest adult emergence, minimum grain damage and weight loss when infested by S. oryzae and S. cerealella. HDPE bag and double layered polythene bag with A. conyzoides recorded per cent damage of 4, 5.70 and 5.0, 7.0 and minimumlosses of 0.61, 0.94 and 0.37, 0.52 by S. oryzae and S. cerealella, respectively. The results demonstrated that it is technically feasible to control post harvest pests of maize in India through enhanced hermetic storage by utilizing locally available botanicals.Keywords

The traumatic loss of an eye is not just the loss of an essential sense organ. It results in life-long agony of not being like others with two eyes, which can see and admire the nature's beauty. As young patients are quite sensitive to peer pressure and for them, the greatest challenges are in the terms of identity and social acceptance, so, early rehabilitation is must in such patients. This article reports on the rehabilitation of a 13-year boy with custom ocular prosthesis for his traumatically injured left eye. The custom made ocular prosthesis fitted over the patient's left eye with ophthalmomalacia, successfully restored the patient's aesthetics and improved his social acceptance thereby, improving his quality of life.Keywords

A three-component broadband seismograph is in operation since January 2007 at the Indian School of Mines (ISM) campus, Dhanbad. We have used the broadband (BB) seismograms of 17 teleseismic events (M ≥ 5.8) recorded by this single BB station during 2008-09 to estimate the crust and upper mantle discontinuities in Dhanbad area which falls in the peninsular India shield. The converted wave technique and the Receiver function analysis are used. A 1-D velocity model has been derived using inversion. The Mohorovicic (Moho) discontinuity (crustal thickness) below the ISM observatory is estimated to be ~41 km, with an average Poisson ratio of ~0.28, suggesting that the crust below the Dhanbad area is intermediate to mafic in nature. The single station BB data shed new light to the estimate of crustal thickness beneath the eastern India shield area, which was hitherto elusive. Further, it is observed that the global upper mantle discontinuity at 410 km is delayed by ~0.6 sec compared to the IASP-91 global model; this may be explained by a slower/hotter upper mantle; while the 660 km discontinuity is within the noise level of data.Keywords

Due to channel interference, dynamic obstacles, channel fading and/or applications‟ bandwidth demands Wireless Mesh Networks (WMNs) experience frequent link failures during their lifetime. Multihop WMNs are equipped with multiple radio and multiple channels in every node. These failures cause severe performance degradation in WMNs. Expensive manual network management is required for their real-time recovery. This paper presents a Reconfiguration Algorithm (RA) which is also embedded with interference aware channel assignment that enables a multi-radio WMN to recover from local link failures to preserve network performance. The proposed method makes necessary changes in local radio and channel assignments in order to recover from failures, by using channel and radio diversities in WMNs. The method uses a default channel for transmission till the reconfiguration is done. Based on current channel and radio associations, feasible local configuration changes available around a faulty area are identified. Then, by imposing current network settings as constraints, RA identifies reconfiguration plans that require the minimum number of changes for the network settings. Based on the generated configuration changes and interference aware channel assignment, the system co-operatively reconfigures network settings among local mesh routers. The results show that the proposed algorithm improves channel-efficiency and throughput and has the ability of meeting the applications‟ bandwidth demands.Keywords

A significant fraction of the total power in highly synchronous systems is dissipated over clock networks. Hence, low power clocking schemes are promising approaches for low-power design. Four novel energy recovery clocked flip-flops have been proposed that enable energy recovery from the clock network, resulting in significant energy savings. The proposed flip-flops operate with a single-phase sinusoidal clock, which can be generated with high efficiency. Clock gating solutions for energy recovery clocking was also proposed. Applying our clock gating to the energy recovery clocked flipflops reduces their power by more than 1000x in the idle mode with negligible power and delay overhead in the active mode. Finally, a test chip containing two Linear Feedback Shift Register (LFSR) one designed with conventional square wave clocked flip-flops and the other one with the proposed energy recovery clocked flip-flops is fabricated and measured.Keywords

A License Plate Recognition (LPR) System is one type of Intelligent Transport systems and is of significant interest because of its potential applications to areas such as highway electronic toll collection, Traffic Monitoring System, speed control, automobile theft prevention, parking lot management, and many other areas. This research work proposes an automatic license plate recognition system for Indian license plates. The system captures the images of the vehicles with a digital camera. An algorithm for the extraction of license plate and an algorithm for segmentation of characters have been designed. A new method is adopted in this work to analyze road images which often contain vehicles and extract LP from natural properties by finding vertical and horizontal edges from vehicle region. Character segmentation is an important step in License Plate Recognition system. There are many difficulties in this step, such as the influence of image noise, plate frame, rivet, the space mark, and so on. This work presents a new algorithm for character segmentation, clustering is used to segments all the numbers of the LP. Eight-Neighbor algorithm is used for the purpose of number segmentation and the prior knowledge in horizontal and vertical segmentation respectively. In this work, character recognition is done by using pattern matching based upon the height and width of the character an algorithm for character recognition is proposed. The performance of the system has been investigated on real images of vehicles captured under various illumination conditions.Keywords

The effect of foliar spray of salicylic acid (SA) and boron along with traditional growth regulators like GA3, NAA and ethephon on growth, flowering and yield of guava variety Arka Amulya was investigated. Salicylic acid 100ppm recorded maximum increase in shoot length, number of leaves and leaf area over control. The minimum day for initiation of flowering (24.33) was taken by ethephon 100 ppm spray followed by SA 200 ppm (25.33). Concerning the effect of chemicals on number of fruits per shoot and fruit set per cent, maximum numbers of fruit (3.18) per shoot and fruit set per cent (74.16) were registered in S A 100 ppm which was statistically comparable to NAA 20 ppm. However, minimum fruit set percentage (35.57) was recorded in control. GA3 50ppm and ethephon 100 ppm increased fruit length and fruit breadth, respectively over other treatments. Maximum yield (12 .30 kg) per plant was registered under treatment SA (100ppm) which found statistically comparable to NAA 20 ppm. The highest TSS and vitamin C content were registered under 20 ppm and boron 200 ppm, respectively. While, the highest B: C ratio (11.18) was recorded from the plant treated with SA 100 ppm.Keywords

The momentous role of small-scale industries in the Indian economy need not be over emphasized. The Industrial Policy Resolution of 1948 rightly enunciated the need for "development of the cottage and small-scale industries under the states". The All India Small Scale Industries Board, which was set up in November 1954 to perform rational thinking about ways and means to develop the small industries, eradicated the old fallacy tiiat "to assist industries was futile".- Evaluation of Sorghum Fodder (RIO) for Cattle and Buffaloes

Sorghum is grown in different parts of our country during summer and kharif as a grain or fodder crop. During recent years several varieties have been introduced/evolved for fodder purposes (Rio, PC-6, PC-1, S-136, IS 4776 etc.) but very limited information is available about their feeding on animal production value (of these fodders). Since no information is available regarding the comparative feeding value of Rio fodder for cattle and buffaloes, the present experiment was taken up to evaluate sorghum (Rio) fodder based ration for Tharparkar cattle and Murrah buffaloes of first lactation.- Effect of Non-Human Primates on Tourism of Kalakad Mundandurai Tiger Reserves and Anamalai Tiger Reserves of Tamil Nadu, India

Objectives: To predict the optimum value of heat transfer coefficient during condensation of refrigerant inside a smooth horizontal tube using Teaching-Learning based Optimization Algorithm. Methods: Refrigerant vapor quality and mass flux are considered as variables. An objective function is formulated based on the Shah’s correlation for heat transfer coefficient. The optimal results predicted by Teaching-Learning based Optimization Algorithm are validated with experimental data. Results: Refrigerant mass flux and vapor quality are varied from 100 to 500 kg/m2s and 0.1 to 0.9 respectively. The optimal value of heat transfer coefficient, refrigerant mass flux and vapor quality predicted by the algorithm are 7.56 kW/m2K, 493 kg/m2s and 0.87, respectively. Conclusions: The Teaching-Learning based Optimization Technique is capable of predicting the optimal set of values for different design and operating parameters.Keywords

Objectives: The maximized nano-fluid Nusselt number and minimized pressure drops are the most effective options for obtaining the enhanced thermal frontiers in solar parabolic trough collector. Methods/Analysis: In view of this, numerous researches had proposed hybrid algorithms for the optimization of the thermal analysis. Obtaining Pareto optimal solution, tending to local optimum point and the time consumption are the main drawbacks of the previous algorithms. Hence, in order to overcome the above difficulties, present work proposes a new innovative approach for optimization of thermal analysis in SPTC. Particle Swarm Optimization (PSO) based solution methodology is proposed to gain the benefits of the global optimum solution and overcome the difficulties of the previous approaches. Findings: In this multi objective nonlinear optimization problem, the effect of Nusselt number and pressure drops are considered as the main objectives to obtain the most beneficial values of the design variables. Inlet velocities, concentration ratio of nano-particles and absorber tube diameter are considered as the most preferable design variables in the proposed optimization problem. Application/ Improvement: Five case studies based on different temperature levels are considered to check the suitability of the proposed solution methodology. Results explore the effectiveness of the proposed approach in the optimization of thermal analysis in SPTC.Keywords

Friction stir welding is one of the most suitable welding processes to join aluminum alloys, thanks to many economical and technical advantages associated with its use. This paper investigates effect of friction stir welding on the microstructure and mechanical properties of solid solution hardening Al-Mg-Mn aluminum alloy. Friction stir weld joints were developed using optimum combination of rotary speed and welding speed. The microstructure evolution in friction stir weld joints was studied by optical microscopy. Fine recrystallized grains were observed in weld nugget zone while thermo-mechanically affected zone showed distorted and unrerystallized grains. Microhardness profiles and stress-strain curves were developed for friction stir weld joints and base material. Friction stir weld joints showed mechanical properties approximately equal to base material. Further, fracture surfaces were investigated using scanning electron microscope to study the mode of fracture.Keywords

In this study, direct runoff hydrograph (DRH) is derived by defining the Nash GIUH parameters in terms of the lag time of the watershed, rather than velocity used in conventional GIUH approach. The proposed approach is tested for its applicability on several isolated rainfall-runoff events of a Himalayan watershed (Gagas watershed within Ramganga basin) located in Uttarakhand state of India. The DRHs derived by the proposed approach were found to be in good agreement (average Nash and Sutcliffe Efficiency (NSE) = 83.2% and relative error (RE) in peak = 5.4%) with the observed DRHs. The proposed approach was also compared with kinematic wave-based GIUH approach and the results of the former approach were found superior to the later. Furthermore, to overcome the complexity involved in manual estimation of geomorphological parameters, an approach based on Melton number and geomorphological information system (GIS) is also proposed and found to be simple and easy-to-use.

Beneficial plant microbe interactions in the rhizosphere are primary determinants of plant health and soil fertility. Plant growth promoting fungi have great effect towards the growth of plant crops. Soil borne pathogenic fungi cause heavy crop losses all over the world. As the use of chemicals for disease control and fertilization causes environmental problems, there is a need for alternative control measures. The most important and economically cultivated plant pea nut was selected to test the growth promotion by antagonistic microorganisms with or without pathogen Rhizoctonia solani. This necessitates a study on plant growth promoting fungi (PGPF) as adequate work has gone on rhizobacteria. The present investigation was made to study the effect of PGPF on the growth of Arachis hypogea (L.) and its role of induction of systemic resistance against Rhizoctonia solani. Forty five rhizosphere fungal isolates were obtained from 12 different cultivated field crops and were screened for their potential to promote growth in Arachis hypogea (L.). The isolate (Cc2) obtained from Cucumis sotivus (L.). Duch.ex. poir was identified as the potential plant growth promoting fungus. The effect of soil inoculation of the selected isolate Cc2 on the growth of healthy plants of Arachis hypogea (L.) and those challenged with Rhizoctonia solani was studied by pot culture experiment. The effect was studied in terms of morphological and biochemical parameters. The overall vegetative growth of plant (ischolar_main and shoot development, dry matter accumulation) and Reproductive growth (pod and seed development). The fungal inoculants improved the growth very effectively both in plants challenged and unchallenged with Rhizoctonia solani. The soil inoculation of Cc2 has improved the chlorophyll content, caroteniod content, anthocyanins content, total soluble sugar content, protein content compare to the untreated plants (T0) and plants infected by Rhizoctonia solani (T1). The phenol and proline contents were found to be more in plants challenged with Rhizoctonia solani. The ability of the selected isolate to produce growth hormones was determined. Results revealed that the selected isolate could produce indole acetic acid and gibberellic acid. The in vitro study by dual culture method revealed that there was a negative interaction (Antibiosis) between the plant growth promoting fungal inoculant (Cc2) and the pathogen Rhizoctonia solani. It could be concluded that the selected isolate Cc2 proved to be a potential fungus in promoting plant growth and yield in Arachis hypogea (L.) and in inducing systemic resistance in Arachis hypogea (L.) against Rhizoctonia solani. Finally Cc2 was identified as Rhizopus sp. in generic level.Keywords

Among the newly developed non-conventional machining process, Electrical Discharge Machining (EDM) is the most popular because of its large industrial applications. EDM is a thermal machining process, which is capable of machining any electrical conductive material irrespective of its hardness and strength. In the last decade many attempts have been made to improve the performance of EDM. This paper deals with the improvement of EDM process by applying ultrasonic vibrations to the tool electrode. Studies have indicated that EDM operation with vibrating tool electrode allows deeper penetration and higher feed rates. This is especially useful during finishing operation, where machining time is reduced with the surface quality of workpiece unaffected. The modified EDM process is well adapted to the production of very intricately shape electrodes. Other major advantages of this process include the reduced recast layer, higher machining rate, low thermal residual stresses, and better metallurgical properties of workpiece. Analysis shows that improved dielectric fluid flushing is responsible for most of the advantages achieved. In ultrasonic assisted EDM process, what seems to be more important is the ability of working without instability, particularly when the gap is narrow.Full Text

Over the last few years, many open source Cloud Management Platforms (CMPs) have come into existence. Developers, Cloud Providers and Consumers need to resolute to a cloud platform which best suits their needs. OpenNebula, CloudStack, Eucalyptus and OpenStack are among the major players that commercially provide a cloud management platform. Having several options to choose from, it can become difficult for new businesses to select a platform which caters to all their needs. However, the market has room for several open source cloud platforms that perform different tasks and finally fit together into an extensive cloud ecosystem. Some existing literatures only compare the basic features of these platforms. The main goal of this paper is to provide a practical reference to help businesses understand the features being provided by the above-mentioned Cloud Management Platforms and assist them in making a selection of a CMP that best suits their requirements. All of these platforms provide Infrastructure as a Service.Keywords

The main objective of this paper is to apply Self-Organizing Map (SOM) based Enhanced Fuzzy C-Means (EFCM) algorithm to color image segmentation which is a crucial problem in computer vision and pattern recognition. Discrete Wavelet Transform (DWT) is applied on the color image. The decomposition level is set to 3. Approximation coefficients are extracted from the decomposed image. Improved Saliency Map (ISM) is computed. Self-Organizing Map (SOM) is trained with approximation coefficients along with ISM values. The resultant image is clustered with EFCM algorithm. Proposed method is validated on Berkeley segmentation dataset and other natural color images. Performance of the method is evaluated by using accuracy, precision, recall, entropy and time. Simulation results showed that the proposed method can achieve good segmentation results with low computational complexity than other methods considered for comparison from the literature.Keywords

The purpose of this study was to develop a projective inventory to measure integrity. The projective inventory (PI) is a 69 item (statements) scale consists of 6 situations designed to measure integrity. Integrity has six dimensions: a) Belief in higher order principles: truth, (b) Money as means not as end, (c) Moral courage: indifference to suffering, (d) Commitment to family and friends, (e) Involvement in corruption and (f) Favoritism. The projective inventory yields a total score and six scores corresponding to the dimensions of integrity. Each score was calculated according to agreement and disagreement to the statements given by the participants during the data collection. The results revealed that the average score on positive dimensions of integrity (moral courage: Indifference to suffering, truth & commitment respectively) were higher than the negative values traits of integrity (involvement in corruption & favoritism). Reliability of the projective inventory integrity is 0.94. The construct (convergent) validity of the test was examined in which the correlation of PI scores with Big Five personality attributes was found to be moderate, which indicates that PI measures something related to existing tools of integrity in slightly different manner. Factor analysis was carried out to find the factor structure of the scale. Factor analysis revealed three factors in terms of indifference to suffering commitment and truth. Taking all the dimensions of integrity together and analyzing the step-wise regression analysis, it was found that indifference to suffering is the best predictor of overall test followed by favoritism, commitment, corruption and truth.Keywords

The study was conducted during spawning season (June-July) to evaluate the effect of Moringa oleifera seeds Petroleum Ether extracts (MPE) on gonad development and maturation of Mystus gulio. A total of 72 individual’s adult Mystus gulio (weighing from 72-110 g) were equally distributed in four different experimental groups in triplicate. Animals were fed with four different isonitrogenous and isocaloric diets viz. T1 (control), T2 (0.5 g MPE/kg), T3 (1 g MPE/kg) and T4 (1.5 g MPE/kg) for 35 days. Result of the experiment showed that the significantly (p<0.05) maximum oocytes growth, gonadosomatic index (GSI) value and hepatosomatic index (HIS) value in T3 experimental group followed by T2 group as compared to control. Histological observation of ovary deciphers the comparatively mature oocytes in T3 group. These mature oocytes are characterized by fusion of yolk granules, oil globules and thickening of egg chorion. Feeding with higher dose of MPE (T4) results in fatty liver and hepatocytes hypertrophy. This higher dose negatively affects the oocyte maturation, GSI and HSI of M. gulio. From the study it is concluded that the inclusion of 1 g of MPE/kg diet will improve the oocyte maturation, GSI and HSI in M. gulio cat fish.
