How the decline in India's harrier population hurts its farmers
Harriers are a group of birds that belong to the hawk family that are active during the day and mostly found in vast open plains and grasslands. There are 16 species of harriers distributed worldwide throughout tropical and temperate regions, and six of these species migrate to India from central Asia and neighbouring areas during the winter. They can travel between 3,500 km and 5,000 km during this migration. Studies on tagged harriers in Africa show that they follow different routes during spring and autumn migrations. We do not really know much about the migration of harriers from India – the routes they fly from, or their breeding grounds – but researchers once found that a tagged harrier from Gujarat migrated to Kazakhstan
High-density Skyrmion matter and Neutron Stars
We examine neutron star properties based on a model of dense matter composed
of B=1 skyrmions immersed in a mesonic mean field background. The model
realizes spontaneous chiral symmetry breaking non-linearly and incorporates
scale-breaking of QCD through a dilaton VEV that also affects the mean fields.
Quartic self-interactions among the vector mesons are introduced on grounds of
naturalness in the corresponding effective field theory. Within a plausible
range of the quartic couplings, the model generates neutron star masses and
radii that are consistent with a preponderance of observational constraints,
including recent ones that point to the existence of relatively massive neutron
stars with mass M 1.7 Msun and radius R (12-14) km. If the existence of neutron
stars with such dimensions is confirmed, matter at supra-nuclear density is
stiffer than extrapolations of most microscopic models suggest.Comment: 27 pages, 5 figures, AASTeX style; to be published in The

Owls of the forest’s edge
It looked like just a few random vertical poles stuck in between carefully-planted paddy fields adjoining the Kalakad-Mundanthurai Tiger Reserve. The poles were crudely
fashioned and topped with flattened pads of hay, stuffed into polythene or white cloth bags
Practical Accomplishment Of Smart Binding Industrial System Using Iot Platform
Supervisory control and also information purchase (SCADA) systems, become part of commercial control system (ICS), have actually been playing vital duties in real-time commercial automation as well as controls. Via the development of 3rd generation, or networks based system, SCADA systems are linked to virtually kinds of networks such as wired, cordless, as well as mobile as well as satellite interaction, however safety and security is still a huge difficulty for SCADA system while interacting within. Web of points (IoT) is a common system, a brand-new breakthrough improvement, for reliable SCADA system, where billions of network tools, with wise picking up abilities, are networked online gain access to. Implementation of wise IoT system, SCADA system will substantially enhance system effectiveness, scalability, and also lower expense. Protection is still a significant concern for both-, as they were originally developed with no concern as well as demands of safety. This research study designed IoT-SCADA system as well as released a safety and security system, using of cryptography based formula, which supplied a protected transmission network while each time interaction happened, in between the area tools in the SCADA system
Neutrality of a magnetized two-flavor quark superconductor
We investigate the effect of electric and color charge neutrality on the
two-flavor color superconducting (2SC) phase of cold and dense quark matter in
presence of constant external magnetic fields and at moderate baryon densities.
Within the framework of the Nambu-Jona-Lasinio (NJL) model, we study the
inter-dependent evolution of the quark's BCS gap and constituent mass with
increasing density and magnetic field. While confirming previous results
derived for the highly magnetized 2SC phase with color neutrality alone, we
obtain new results as a consequence of imposing charge neutrality. In the
charge neutral gapless 2SC phase (g2SC), a large magnetic field drives the
color superconducting phase transition to a crossover, while the chiral phase
transition is first order. At larger diquark-to-scalar coupling ratio
, where the 2SC phase is preferred, we see hints of the
Clogston-Chandrasekhar limit at a very large value of the magnetic field
(G), but this limit is strongly affected by Shubnikov de
Haas-van Alphen oscillations of the gap, indicating the transition to a
domain-like state.Comment: 19 pages, 7 figures, Matches with the published versio
Conservation of a fragmented population of blackbuck (Antilope cervicapra)
The Vallanadu Blackbuck Sanctuary (VBS), Tamil Nadu, India is a small protected area (PA) designated to conserve blackbuck. We did a study on habitat use and suitability in the PA that has come under various
management interventions. The occupancy of blackbuck
was positively correlated with areas lying within the PA, but the encounter rate of blackbuck was significantly
higher in areas outside the PA. Being small in size, VBS may not hold a large population of blackbucks, but may help in saving the species which once widely occurred in the southernmost parts of India
Muon production in low-energy electron-nucleon and electron-nucleus scattering
Recently, muon production in electron-proton scattering has been suggested as
a possible candidate reaction for the identification of lepton-flavor violation
due to physics beyond the Standard Model. Here we point out that the
Standard-Model processes and can cloud potential beyond-the-Standard-Model signals in
electron-proton collisions. We find that Standard-Model cross
sections exceed those from lepton-flavor-violating operators by several orders
of magnitude. We also discuss the possibility of using a nuclear target to
enhance the signal.Comment: 24 pages. Additional figure showing energy-dependence of total cross
section, minor changes to text. Conclusions unaltered. This version to appear

Multibiometric Authentication System Processed by the Use of Fusion Algorithm
The present day authentication system is mostly uni-model i.e having only single authentication method which can be either finger print, iris , palm veins ,etc. Thus these models have to contend with a variety of problems such as absurd or unusual data, non-versatility; un authorized attempts, and huge amount of error rates. Some of these limitations can be reduced or stopped by the use of multimodal biometric systems that integrate the evidence presented by several sources of information. This paper converses a multi biometric based authentication system based on Fusion algorithm using a key. Our work mainly focuses on the fusion algorithm, i.e fusion of finger and palm print out of which the greatest features from the above two traits are taken into account. With minimum possible features the fusion of the both the traits is carried out. Then some key is generated for multi biometric authentication. By processing the test image of a person, the identity of the person is displayed with his/her own image. By the fusion algorithm, it is found that it has less computation time compared to the existing algorithms. By matching results, we validate and authenticate the particular individual
Effect of a hydrotherapy based alternate compress on osteoarthritis of the knee joint: a randomized controlled trial
Background: Osteoarthritis (OA) of the knees causes pain; swelling and decreases its range of motion in the knee joint. An alternate hot and cold compress gives a circulatory effect without thermic reaction. This treatment induces only a revulsive, non-excitant, and analgesic effect, till date there have been no investigations on the usage of an alternate hot and cold compress as an intervention in individuals with OA of knees.Methods: The control group (n=30) received only routine naturopathy based treatments, whereas the study group received naturopathy based treatments along with an alternate hot and cold compress as an additional intervention for 10 days. Subjects were assessed with Numerical Rating Scale (NRS) and Knee injury and Osteoarthritis Outcome Score (KOOS) as standard questionnaires at baseline and at the end of 10 days.Results: To perform statistical analysis of the collected data we use Kolmogorov-Smirnov goodness of fit test to validate the assumption of normality. We applied Paired sample t – test to test the effectiveness before the treatment and after the treatment in Control group as well in Intervention group. We use independent two sample t-test to test effectiveness of treatment. Results of NRS and KOOS questionnaire are expressed as mean and standard deviation and P value (< 0.05). There was a significant reduction in pain in experimental group compared to control group P value (< 0.05).Conclusions: This study concluded that an alternate hydryatic compress was effective in the management of pain in knee OA
Evaluation of hyperglycaemic risk of atorvastatin: a dose dependent study on hyperlipidaemic rats
Background: Statins (β-hydroxy β-methylglutaryl-CoA (HMG-CoA) reductase inhibitors) are the most prescribed medications worldwide to treat hyperlipidaemia with a proven ability to reduce major cardiovascular events. Recent data have revealed that statin therapy is associated with an increased risk for developing diabetes. The risk was most significant in patients taking atorvastatin, rosuvastatin and simvastatin.Methods: Rats were divided into 3 groups, each comprising of 6 rats. Hyperlipidaemia was induced in all the animals after feeding with high fat diet for 15 days. Rats of groups 1, 2 and 3 were given atorvastatin 1.8 mg/kg (low-dose), 3.6 mg/kg (moderate-dose) and 7.2 mg/kg (intensive-dose) respectively orally for 60 days. 12 hours fasted blood samples were collected and analyzed for serum lipid profile, fasting blood glucose and HbA1c levels.Results: The percentage increase in plasma blood glucose after 60 days of treatment in groups 1, 2, and 3 is 29.93%, 60.03% and 72.42% respectively and the variation in all the groups is statistically significant, p<0.0001. Regarding HbA1c values, the variation in low-dose group is statistically insignificant whereas the percentage increase in moderate-dose and intensive-dose groups is 19.45% (p<0.001) and 43.37% (p<0.0001) respectively.Conclusions: In conclusion, there is significant increase in blood glucose and HbA1c levels leading to new-onset diabetes in both moderate-dose and intensive-dose groups. The risk is more in intensive-dose group when compared to moderate-dose group
