A study was carried out during 2005-2007 on morphological characterization of Terminalia tomentosa W&A. germplasm in the field gene bank at Central Tasar Research and Training Institute, Ranchi. A total of 50 accessions were grouped into 17 different morphological descriptors. Plant nature was erect in most of the accessions (45) except in 5 accessions where it was spreading in nature. Leaf shape was ovate (27), elliptical (16), lanceolate (4), oblique (2) and obovate (1) in the accessions studied. Most of the accessions showed pubescence in the leaf and only 2 accessions had glabrous nature of leaf. Phyllotaxy was of opposite type in all the accessions. Maximum accessions have medium size of lamina length except in 15 accessions where it is of large size. Twenty six accessions have medium and fourteen accessions have short internodal distance. Leaf moisture was medium in 42 and high in 3 accessions. This characterization will help in isolating the economically useful accessions for future breeding programme in Terminalia tomentosa.Keywords

This paper evaluates the relative efficacy of plantations of different tree species in improvement of high pH soil. The 12 tree species studied in general were effective in bringing about improvement in the soil properties as reflected by the changes in pH, EC, organic carbon, available nitrogen, phosphorus and potassium. Higher available N, P2O5 and K2O as well as higher organic carbon percentage were noted under canopy of Albizia procera followed by Leucaena leucocephala. The pH and EC were lowest under Albizia procera and changes were observed from 8.7 to 7.7 and 0.76 to 0.40 dS m-1, respectively in the span of 12 years. Albizia procera produced maximum litter fall (13.95 t ha-1year-1) followed by Leucaena leucocephala (13.25 t ha-1year-1) plantation. The nutrients returned through litter fall followed the order N>K>P in all the tree species and was helpful in reclamation of high pH soils.- Vegetative Propagation of Terminalia myriocarpa Through Cuttings

Studies for seed morphology, seedling growth and biomass attributes were made in 25 provenances of Terminalia arjuna (11) and T. tomentosa (14). A wide variation was recorded for 13 seed and seedling traits in both the species. Single seed weight ranged between 1.15 to 4.52 g in T. arjuna and 0.87 to 2.76 g in T. tomentosa. Germination per cent was maximum (83.33) in T. arjuna seeds from Chakradharpur (Jharkhand). Production of fresh biomass was maximum (2.03 g) in T. tomentosa seedlings from Kharsawan (Jharkhand). Root shoot ratio an important parameter in initial establishment of seed ling was also highest (3.08:1) in seedlings of T. tomentosa from Ranka (Jharkhand).Vigour index ranged between 669.80% (T. arjuna) to 580.80 % in T. tomentosa. A positive and significant correlation was found between emergence index and germination per cent, germination speed, ischolar_main length and vigour index. Based on the vigour index, ischolar_main/shoot ratio plus trees of T. arjuna from Chakradharpur and Garwha and of T. tomentosa from Baharagoda have been identified for multiplication.Keywords

The present paper presents conditional probabilities of occurrence of moderate earthquakes considering the likelihood of occurrence of the next large earthquake in the seismically active regions in India where the last such occurrence has crossed the return periods. The conditional probabilities have been estimated using Weibull distribution. The estimations have been carried out for 24 seismogenic sources earmarked in the Indian subcontinent. The cumulative and conditional probabilities have been interpreted with respect to the last earthquake occurrence in the time intervals of 15 and 50 years. Most of the seismically active regions are found to have lesser recurrence of earthquakes with specific magnitudes as compared with the estimations being carried out using classical probabilistic seismic hazard assessment approach.Keywords

Sediment build up, structure and geomorphic setting of alluvial fans can serve as good clues for the reconstruction of Quaternary events in a region where they are located. Alluvial fans assume greater importance especially in young orogenic belts like the Himalaya where there has been an interplay of rapid uplift and global climatic change during the Pleistocene. In this paper an attempt has been made to study the genesis of a small relict debris fan in the upper Spiti valley in the Tet hys Himalaya (H.P.) and to elucidate its sedimentational style in local climatic and tectonic set up. The fan has been essentially constructed by debris flows and subordinate stream deposits during seasonal melting and episodic events of the late Quaternary. While climate remained much the same local tectonic activity leading to upliftment of the fan and diversion of the feeder channel ceased further accretion of the fan beyond its present size. Minor warmer climatic oscillations within the main cool phase are observed.Keywords

The present study pertained to records on milk production and milk constituents of 259 Sahiwal cattle with 600 lactations spread over a period of 10 years from 2001 to 2010, collected from Dairy Cattle Breeding division of National Dairy Research Institute, Karnal, Haryana. To study the effect of various genetic and non-genetic factors on milk yield and milk constituents traits, mixed model least square analysis was used for analysis of data. Overall least square mean for all lactation traits of total milk yield (TMY), milk yield in 305 days or less (305MY), lactational average fat per cent (LFA) and lactational average solid not fat per cent (LSA) were 1880.39 ± 73.82 kg, 1782.97 ± 68.37 kg, 4.71 ± 0.01 per cent and 8.81 ± 0.01 per cent, respectively. Analysis of variance showed that the differences were statistically significant for the effect of sire on TMY and 305MY; period on all the traits except TMY; parity on 305MY. However, the effect of season of calving was not found significant on all the traits.Keywords

Objectives: This aim of this paper is to analyse different approaches for transient fault tolerance like PBS, RM-FT, FSP, BCE and MWFD. Methods: Transient faults are emerging as a critical issue in the reliability of real time systems. Besides multiprocessors being an apparent part of various booming technologies now-a-days, it becomes evident to make these systems susceptible, reliable and consistent to transient faults. Thus, to address the increasing susceptibility of multiprocessors systems to transient faults, different approaches are analysed to counter transient faults. Findings: To identify the optimal method for various constraints like slack time, reduction in time space and reconfiguration etc. Applications: This comparative analysis will help for us to identify the optimal approaches for tolerating the transient fault in critical real time systems.Keywords

In the last decade the advent of ART has proven to be a boon for the infertile couple. In a large number of infertile couples there may be a genetic basis. Such couples who harbor genetic abnormalities need to be provided comprehensive counseling prior to opting for ART. Despite state of art technology and professional expertise, the carry home live-birth rate in ART is low. One of the factors responsible for low success rate of ART in couples opting for ART could be genetic. We analyzed 350 couples with recurrent spontaneous abortions (RSA) among whom 86 were couples with recurrent ART/ICSI failure. All couples with 3 or more ART failures were referred for cytogenetic, Yq microdeletion and mitochondrial mutation analysis. Among these 86 couples cytogenetic abnormalities were detected in 32 (20 cases in the male and 12 cases in the female). Yq microdeletions were detected from genomic DNA isolated from blood in 7 men whereas 9 men showed Yq microdeletions in DNA isolated from spermatozoa. High frequency of mitochondrial mutations and deletion of 4977 were also detected in sperm DNA (n=3) and blood of the female partner (n=4). These genetic abnormalities may be iatrogenically transmitted to the offspring. In cases with sex chromosomal and autosomal aberrations there is probability of poor embryo development and, consequently, implantation failure and early fetal loss. ART is a very expensive technique and recurrent ART/IVF failure would result in severe financial burden and physical stress, coupled with emotional stress. It is suggested that all couples opting for ART must undergo genetic analysis.Keywords

Background: Substituted dihydropyridine calcium channel blockers are used in the treatment of cardiovascular diseases. Dihydropyridines are considered as analogue of dihydropyrimidines.
Objectives: In present study newly synthesized test compound 5- Acyl-6-methyl-4(2',3'-methylenedioxy) phenyl - 2 - S - ethyl - 1, 4- dihydropyrimidine, a dihydropyrimidine derivative was investigated with an aim to get valuable substitute for the well known dihydropyridine, Nifedipine.
Material & Methods: The Calcium Channel blocking actiuity of test compound was studied on Rabbit's Heart and its effects were compared with Nifedipine used as control.
Results: Test compound has dose-dependent negative chronotropic and negative inotropic effect on Rabbit's heart but these effects appeared at doses higher than those of Nifedipine. Test compound had no significant change in coronary flow however Nifedipine show significant increase in coronary flow at lower doses.
Conclusion: Test compound appears to be less potent myocardial depressant compared to Nifedipine. Test compound produced calcium channel blocking activity which was dose related and in order to ascertain the status of this compound as a drug, further studies are needed not only in other animals and tissue models but also in various pathophysiological models.

Male child preference is a well known phenomenon in Indian society. There are various drugs and techniques used to achieve this target, even though these are illegal and punishable. Women desirous of male child try to procure these drugs which are supposed to help in sex selection. These secretly procured drugs can cause congenital defects in the fetus due to the fact that these drugs are always administered during first trimester - the most vulnerable period for the fetus. There are many drugs, whose teratogenic potential is already known. But in the absence of enough data and lack of clinical trial studies in pregnant women, we don't really know about many drugs, which are necessary for various medical conditions during pregnancy. On top of that these so called sex selection drugs add to an unhealthy practice leading to many more probable congenital anomalies. It is the need of the hour that proper data is collected about all such drugs and their implications is studied on fetus. Due to secret prescriptions, it may be difficult to ban such drugs, but public awareness and health education about congenital anomalies caused by such drugs is probably the only way to fight this menace.Full Text

The use of drugs to increase human happiness and to improve the quality of life physically, mentally and socioeconomically is a serious matter of concern. Chronic disabling conditions become common in old age and affect the quality of life. Quality of life (QOL) is an important measure of health care, which measures the gap between expectations and achievements. Effect of Drug use on quality of life in elderly Indian population with hypertension was studied using Mc Master Health Index. The study population was divided into test group (hypertensive patients on regular treatment) and control group (Not on any treatment or on treatment for less than 3 months). All three parameters of QOL namely physical, emotional and social were studied using Mc Master Health Index questionnaire. The results were statistically compared using ANOVA and chi square. Our results point toward better overall QOL in patients on regular treatment.Keywords

Background: Hepatorenal syndrome is the development of renal failure in patients with advanced liver cirrhosis, occasionally fulminant hepatitis, who have portal hypertension and ascitis in the absence of some other kidney disease.
Objective: To study the clinical profile of hepatorenal syndrome.
Methods: All patients of chronic liver disease with renal involvement were studied and patients fulfilling the criteria of hepatorenal syndrome were recruited in the study. The etiology, clinical presentation, morbidity and outcome of patients were recorded. Various variables were studied between survivor group and non survivor group to detect possible predictors of non survival in hepatorenal syndrome. The data was analyzed using SPSS software.
Results: 42 patients of hepatorenal syndrome were clinically evaluated. 95% were males and 5% females with mean age of 50.29±8.87 in survivor group and 45.92±10.1 in non survivor group. High level of serum bilirubin, hepatic encephalopathy, decreased level of albumin, hyponatremia and coagulopathy were significant in non survivor group as compared to survivor group.
Conclusion: The poor prognostic factors were found to be ascites, severe jaundice, hepatic encephalopathy, alcohol abuse, hypoalbuminemia, progressive renal failure and child pugh score greater than 10. Thus hepatorenal syndrome is decompensated cirrhosis which needs judicious treatment especially using terlipressin and albumin.

Cognitive radio devices will be able to sense and dynamically use frequency bands for network access. This will be done by autonomous detection of unoccupied bands in the radio spectrum. Several factors like fading and shadowing affects the ability of the cognitive radio to detect the primary user. The current research shows that cooperation among the cognitive users can increase the detection probability for a given probability of false alarm. Previous research work shows that, the probability of detection is achieved maximum of 0.9 in AWGN channel. In this paper, we propose a new method for capacity maximization by minimizing probability of signal outage. And also increases the probability of detection by increasing sensing time for Rayleigh fading channel. Simulation results show promising performance results of the proposed technique are increased probability of detection and considerably maximizing the channel capacity.Keywords

Highly variable round-trip times (RTTs) in wireless networks can induce spurious timeouts, thus unnecessarily degrading throughput for the Transmission Control Protocol (TCP). In this paper, we propose and study two effective ways to improve TCP throughput in wireless networks. The first technique is to select a retransmission timeout (RTO) threshold higher than that in the de facto standard. Simulation reveals that the proposed method reduces timeouts and provides a relative throughput gain up to 13.7% based on RTT measurements in a commercial 3G network and in a simulated network environment. The second technique is an appropriate use of selective repeat (SR) and go-back-N (GBN) as retransmission policies upon packet timeout. We find that when RTTs have reasonable temporal correlation and packets can arrive out-of-order at the receiver, GBN can improve throughput over the SR policy. Specifically, based on the RTT measurements in the 3G network, our results show that GBN provides a 12% throughput gain over the SR policy.

The wide-band code division multiple access (WCDMA) based 3G and beyond cellular mobile wireless networks are expected to provide a diverse range of multimedia services to mobile users with guaranteed quality of service (QoS). To serve diverse quality of service requirements of these networks it necessitates new radio resource management strategies for effective utilization of network resources with coding schemes. Call admission control (CAC) is a significant component in wireless networks to guarantee quality of service requirements and also to enhance the network resilience. In this paper capacity enhancement for WCDMA network with convolution coding scheme is discussed and compared with Block code and without coding scheme to achieve a better balance between resource utilization and quality of service provisioning. The model of this network is valid for the real-time (RT) and non-real-time (NRT) calls having different data rate. Simulation results demonstrate the effectiveness of the network using convolutional code in terms of capacity enhancement and QoS of the voice and data services.

The wide-band code division multiple access (WCDMA) based 3G and beyond cellular mobile wireless networks are expected to provide a diverse range of multimedia services to mobile users with guaranteed quality of service (QoS). To serve diverse quality of service requirements of these networks a new radio resource management strategies for effective utilization of network resources is required. For that Adaptive Multi-Rate (AMR) will be used for voice applications in universal mobile telecommunication System (UMTS) systems where high spectral efficiency and system stability are required while guaranteeing a good speech quality. To investigate the trade-off between the system resource utilization and the provided quality of voice services, by proposing a method that considers both aspects of quality and capacity for the optimal assignment of speech data rates in 3rd generation cellular systems in this paper. So a new Call Admission Control (CAC) scheme is proposed to enhance capacity of WCDMA network based on the utilization services with AMR for different decision decoder. The model of this network is valid for the real-time (RT) and non-real-time (NRT) calls having different data rate. Simulation results demonstrate the capacity of the network using utility based CAC scheme with soft decision decoder is higher than that of hard decision decoder.Keywords

Next generation wireless network is envisioned as a convergence of different wireless access technologies providing the user best connection any where any time to improve the systems resource utilization. In such converged systems, the heterogeneous co-existence of access technologies with largely different characteristics results in handoff asymmetry that differs from traditional intra-network handoff (horizontal handoff) problem. The seamless and efficient handoff between different access technologies (vertical handoff) is essential and remains a challenging problem. The parameters measured to determine handoff are received signal strength, signal to noise ratio and bit error rate. In this paper, an analytical framework to evaluate the performance of vertical handover between wireless access networks in terms of received signal strength, is validated by simulation. It is likely that WLAN will become an important complementary technology to 3G cellular systems and typically used to provide hotspot coverage where there is a high density of users.Keywords

Vegetables form an essential component of the meal by providing vitamins, minerals such as iron, calcium, magnesium, zinc and other nutrients important for human health. In most developing countries, vegetables are most reliable source of minerals and vitamins. The vegetables contribution of minerals and vitamins to human nutrition is however limited due to the presence of antinutritional factors that render some of the nutrients unavailable for human nutrition. The most common antinutritional factors in vegetables are oxalic acid, phytic acid and tannic acid. Oxalate is a common constituent of plants, which accumulate higher levels of dicarboxilic acid anion.- Modelling and Simulation of Object Detection in Automotive Power Window

The paper focuses on the system modelling of hardware based power window control system. In power window system, Direct Current (DC) motor served as the source of power to drive the power window frame and accordingly power window can be raised and lowered. In the paper, mathematical model of a DC motor controlled by an H bridge circuit and bridge is controlled through input switches which are available at driver and passenger door side. The main objective of power window control is to control the movement of glass door in upper and lower direction and this operation is controlled with the help of current sensor, fire sensor and position sensor in the replacement of manual control hand turned crank techniques for existing power windows. The driving component is DC motor that drives the power window using selflocking techniques for worm gear in the minimum ratio of 1:50 and output of worm gear goes to lead screw having pitch of 3mm to deliver linear movement to power window. The control unit of power window senses both high and low load obstructions. It is used to activate and deactivate the movement of the glass door in upward direction and downward direction with the help of DC motor, whenever, any hard and soft obstruction is detected. The automatic power window with intelligent control is designed and verified with several conditions that claim its movement in upward and downward direction. The simulation model is visualized in MATLAB/Simulink and performance is analysed with respect to current, voltage and speed measurement.Keywords

Ultra Wide Band (UWB) technology is a fast emerging technology for short distance wireless communication. UWB plays a preeminent role in the short range wireless systems, due to the advantages of high speed, low power consumption and very high security. Methods/Statistical Analysis: With cooperative communication as a decisive member in its side this paper proposes cooperative MB-OFDM communication using effective grouped relays in multichannel with use of Dual Carrier Modulation (DCM) for UWB systems. We can attain maximum diversity by using simple Maximum Likelihood (ML) receiver without reduction of data rate as its found using almounti coding which is most used to provide diversity in cooperative communication. Findings: The Proposed method’s resulting diversity is observed using outage probability as a basic parameter and also how the outage probability varies in accordance to threshold power. Application/Improvements: The results shows an improved BER versus SNR with effect of CFO is considered and the improvement in channel capacity and data rate of various different modulation schemes is obtained by varying SNR and distance.Keywords

Background/Objectives: In underlay cognitive radio network, the power control systems play a major role where the secondary users should not affect the primary users transmission. The interference constraints are not attained by all users as the Signal to Interference Noise Ratio (SINR) of the target requirement is not satisfied in the distributed algorithm for power control. Hence, an algorithm is proposed to reduce the power and to regulate the interference constraints of the primary and secondary users. The SINR also has to be maintained. In the proposed method, the distributed statistical algorithm is used when the interference constraints is not available when all transmitters are in active mode to obtain an efficient solution. Methods: In order to minimize the level of SINR for each link between primary and secondary user, a distributed algorithm for power control is proposed. The traditional power control algorithms are used to maintain the secondary users transmission within specific power levels. The main drawback of the traditional algorithms is that the constraints are not met when all the transmitters are active. Result: A Power minimizing algorithm along with the distributed statistical elimination algorithm, to suppress the transmission of selected number of links when all the nodes are active is proposed. This satisfies the SINR requirement of the secondary links. Application: The proposed elimination algorithm enables the optimized power distribution, hence it is a more practical solution in networks with increased number of secondary users.Keywords

Pre-harvest application of calcium chloride (0.5, 1.0, and 1.5 %) and gibberellic acid(10, 20 and 30 ppm) at 80% blooming, fruit-set and at 15 days before harvest were carried out on 5-year old trees of apricot cv. Harcot. All the treatments significantly reduced physiological loss in fruit weight, fruit diameter and spoilage percentage during storage. However, CaCl2 @ 1.5% was found to be most effective in minimizing weight loss in fruits during storage compared to Control. Fruits quality (TSS, titrable acidity, TSS/TA, ascorbic acid, total sugar, etc.) was also found to be better (even at 8 days of storage at ambient condition with this treatment) compared to Control. Hence, it can be concluded that pre-harvest foliar application in apricot cv. Harcot with CaCl2 @ 1.5% at three stages, i.e., 80% blooming, at fruit-set and 15 days before harvest, enhances shelf-life of the fruit from 3-5 days storage to 8 days storage, and can maintain good fruit quality under ambient storage-condition for up to 8 days.Keywords

In this paper, a rectangular microstrip patch antenna (MPA) is designed using different substrate materials for analyzing the performance of the MPA. Alumina (Al2O3), Bakelite, Beryllium oxide (BeO), Gallium Arsenide (GaAs), RT-Duroid and Flame Retardant 4 (FR-4) are the six different substrate used in the design. The size of the rectangular microstrip patch antenna varies according to the dielectric constant of substrate materials used. The operating frequency taken for this analysis is 5.8 GHz. The proposed design provides the study on the performance of rectangular microstrip patch antenna for different substrate materials using the same frequency. This study conveys that which substrate material provides better performance. Moreover, this comparative study conveys that which substrate material provides better performance. The simulation parameters are investigated using HFSS.Keywords

Materials and Methods: A 6 weeks feeding trial was conducted with 280-day-old Ven Cobb broilers, distributed randomly into seven experimental groups. Each treatment had 4 replicates with 10 birds each. The birds of the control group (T1) were fed a basal diet formulated as per BIS standards. The broilers of treatment groups T2 and T3 were fed basal diet supplemented with the commercially available garlic powder (GP) at levels of 0.5% and 1.0% of the feed, respectively, while broilers in T4 and T5 were fed basal diet supplemented with commercial grade holy basil leaf powder (HBLP) at levels 0.5% and 1.0% of the feed, respectively. Birds in the T6 were fed with 0.5% GP and 0.5% HBLP, whereas T7 was fed with 1.0% GP and 1.0% HBLP. At the end of the feeding trial (6th week), blood samples were collected and analyzed for relative mRNA expression of toll-like receptors (TLR) 2, TLR 4 and TLR 7 using real-time polymerase chain reaction.
Results: The mean body weight gain and feed conversion efficiency were improved (p<0.05) in broilers fed the GP and HBLP incorporated diets compared with the control group. The relative mRNA expression levels of TLR 2, TLR 4 and TLR 7 in the peripheral blood of the broilers were found to be increased (p<0.05) in the birds supplemented with graded levels of the GP and HBLP as compared to the untreated group.
Conclusion: The present work concludes that the inclusion of GP and HBLP could enhance the production performance and immune status of birds by augmenting the T-cell mediated immune response and thereby protects them from disease without decreasing growth traits as a possible substitution to conventional antimicrobials.

The severity of duty of the steam generator, particularly, in the utility industry, has increased beyond proportions in the last two decades. While the cycle conditions have become very ardous with very high pressures, temperatures and evaporations, the quality of fuels, be it coal or oil, has been subjected to a steady deterioration. This much of progress would not have been possible'had the development of new materials by the metallurgists not kept on equal pace.- Study on Weldability of EN 10025-6 S550 QT Steel

Cracks developed in the 90 mm thick EN 10025-6 S550 QT steel plates assembled to form a box unit. After assembly the surface cracks generated longitudinally along the elongated grains while preheating or performing ischolar_main run. Root cause analysis was conducted to investigate the reason for the failure and also how to specify the “conditions of materials on delivery” during procurement is generated. Various tests such as visual test, chemical composition, inclusion rating, microstructure, dye penetrant test and hardness tests were conducted. The investigation revealed that the failure cracks could be due to temper embrittlement due to the segregations of impurities such as tin, arsenic, phosphorus and antimony, etc. in the grain boundaries and resulted in ductile to brittle transformation when exposed in the temperature. It is observed that, depends on the concentration of Ti and N in steel, coarse and cuboidal TiN particles of several micrometers in size act as potential sites for cleavage crack initiation. Furthermore, during the steel making process if sulfur is not properly controlled, then large MnS inclusions can also form during solidification. Soft MnS inclusions elongate during the subsequent hot rolling process, which deteriorate ductility and impact toughness. Hence, it is essential to specify the J factor value and inclusion rate during the procurement of steel.Keywords

EN10025-6 S550Q is high strength steel classified under quenched and tempered (Q&T) manufacturing technique. S550Q is specially designed and used by the authors for welded steel structures for the purpose of heavy lifting and lowering. The entire processing techniques like cutting, edge preparation, welding, and bending are of major importance to the consistency of fabricated structure. This study comprises of introduction to HSS-S550Q and addresses various important variables by practically. The following main factors are taken to consideration heat input during cutting, edge preparation, and welding, cooling cycle, Hydrogen induced cracking (HIC). Stress Relieving (SR) is mandatory after weld fabrication. The first was to establish a need for SR to achieve desirable weldment properties. SR has been reported to have Complementary benefits such as tempering of WM and HAZ regions, and allowing the effusion/diffusion of hydrogen away from the weld region. Bend testing of cross-weld samples was used to qualify the ductility of the weldment before and after SR. In addition, impact, tensile and hardness properties, microstructures were quantified before and after SR.Keywords

The present investigation is concerned with effects of distinct conductive and thermodynamic temperatures on reflection and transmission cofficients at an interface of two different micropolar viscothermoelastic solid half spaces. Reflection and transmission phenomenon of plane waves impinging obliquely at a plane interface between two different micropolar viscothermoelastic solid half spaces with two temperatures are investigated in the context of Green-Lindsay (G-L) theory (1972). The incident wave is assumed to be striking at the plane interface after propagating through one of the micropolar viscothermoelastic solid with two temperatures. Amplitude ratios of the various reflected and transmitted waves are obtained in closed form and it is found that these are function of angle of incidence, frequency and are affected by the micropolar, viscoelastic properties of the media. Viscosity effects are shown on these amplitude ratios for a specific model. Results of some earlier workers have also been deduced from the present investigation.Keywords

Steroidal glycoalkaloids, a category of glycosidic ingradients are originated from nitrogen-containing steroids. Structurally it includes of C27 cholestane skeleton to that 1 to 5 sugar moieties are hooked up at the 3-OH region of the aglycone part. Solasodine, in most of the solanaceous plants occurs as an aglycone a region of glycoalkloids, like solasonine, solamargine etc. Solasodine is employed as a hormone precursor within the steroid drug business for the manufacturing corticosteroids, anabolic steroids, antifertility drugs etc. Isolated Solasodine from solanum plants exploits its medicinal properties such as anticonvulsant, CNS depressant, antioxidant, cytotoxic, antinociceptive, anti-inflammatory, hepatoprotective, immunomodulatory, antiatherosclerotic, antimicrobial, and antiobesity activity, etc. In acut toxicity study, LD50 of Solasodine was found to be 1500 mg/kg after intraperitoneal administration and 2000 mg/kg, after oral administration in rats. Present review has set about to bring updated information regarding to pharmacological activities of solasodine, which may be helpful to researchers to explore a new bioactive molecules for various therapeutic application.Keywords

In the era of Anthropocene, characterized by a dramatic increase in anthropogenic pressure, global changes are challenging the capacity of planet Earth to sustain the development of human societies in the long term. In the past two decades, this concern has fostered worldwide efforts to develop integrated studies of the ‘critical zone’ (CZ), the outer skin of the Earth, extending from the canopy top to the bottom of the aquifer, hosting the continental biosphere and providing basic human needs such as water, food, energy and ecosystem services1 . Environmental processes within the CZ, such as energy and mass exchange, formation of soil, streamflow and evolution of landscape are critical to sustain biodiversity as well as humanity 2,3 . However, with rapid socio-economic development, the CZ is subjected to increasing stress from anthropogenic forcings such as the growth in human and livestock populations, increase in land use, global environmental changes, and expanding consumption patterns4 . The expanding needs for sustainable development call for understanding, predicting and managing the complexity as well as dynamics within the CZ and to study its feedback with other compartments of the environmental systems5,6 . The main challenge faced by the CZ research is to integrate effectively the multiple disciplines at stake, from geosciences, biological sciences, ecology, hydrology, soil science to social sciences, working within a wide range of temporal and spatial scales7,8 . The interdisciplinary and multiscale study of terrestrial ecosystem processes can be best addressed by critical zone observatories (CZOs), where domain experts across different disciplines study various aspects of the CZ. This will lead to holistic understanding of complex systems 8 .Full Text

Human inventions have been developing since the Stone Age. From the invention of the wheel to the progress of today’s best truck. In the process of evolution, humans have improved their ability to traverse different terrains. On each occasion, due to the height and inclination of the obstacles, portability has been hampered. Most of the obstacles with a gentle slope have been effectively overcome. However, due to unstable obstacles, the vehicle did not pass through. Consider the suspension components of the 4-bar tipping bogie. To ensure the great flexibility of the bogie, the turn should be kept in a reasonably expected low position while maintaining maximum ground freedom.
To design a vehicle that can climb a 90 degree slope, the basic 4 bar tipping bogie instrument has been used with a trapezoidal front fork to give the vehicle a 90-degree slope climbing obstacle. An inflated tire can expand the vehicle’s wheelbase and keep the focus of gravity on the frame even when climbing obstacles. Through the above changes, the vehicle can climb a deterrent with a height twice the width of the wheel and a lean point of 90 degrees. Using this mechanism in the mining robots can be accomplished various applications such as mining, robotic excavation, transportation, robotic surveying, robotic drilling, and handling explosives. Tipping bogie suspension will become an alternative mechanism for super terrain mining.
