Acronicta rumicis (Linnaeus, 1758), Emerging Pest of Apple Plantation in Kashmir Valley
National Academy Science Letters - Tập 42 - Trang 287-289 - 2018
The larvae of the moth Acronicta rumicis Linnaeus commonly known as Knot grass moth inflict considerable damage to new apple plantation in the Kashmir region. Immature stages of the pest defoliate apical buds and result in stunted growth of the plant. Seasonal occurrence and severity of the pest from Kashmir Valley is detailed.
WASN: WiMax Based ad hoc and Sensor Network Event Monitoring—A Unique Management Architecture
National Academy Science Letters - Tập 38 - Trang 343-347 - 2015
The improvement on network operation by monitoring the event status of various facilities has gained attention recently. In this work, a new event correlation and monitoring scheme is proposed based on WiMax network with localized computation and available resources. In Wireless network, especially 4G WiMax network has advantages in mobility, coverage and scalability. This work helps to resolve th......
Scale Invariance of Power Spectrum in Sediment Transport Mechanics
National Academy Science Letters - Tập 41 - Trang 81-83 - 2018
Flume experiments were carried over a curvilinear mobile sand bed and over a vegetated sand bed to scale the power spectra variation in the longitudinal velocity spectrum of turbulence flow. Instantaneous three dimensional velocities were sampled using an acoustic Doppler velocimeter; sequentially spectral analysis of the filtered velocities is consummated. Results depict that slope of power spect......

A Prefatory Estimation of Diversity and Distribution of Moths in Nanda Devi Biosphere Reserve, Western Himalaya, India
National Academy Science Letters - Tập 40 - Trang 199-203 - 2017
A pilot assessment of moth distribution and diversity was conducted in the buffer zone of Nanda Devi Biosphere Reserve, Western Himalaya, Uttarakhand, India. A total of 771 specimens were collected along an elevational gradient between 2000 and 3800 m across different forest types (temperate, sub-alpine, alpine scrublands) in Joshimath and Lata. Specimens were collected using light-trapping method......
Entanglement of the Non-Gaussian Two-Mode Quantum Vortex State
National Academy Science Letters - Tập 43 - Trang 77-80 - 2019
We study the entanglement properties of a non-Gaussian two-mode vortex state that was theoretically proposed by Agarwal [New J Phys 13:073008 (2011)] by using the technique of photon subtraction from a two-mode squeezed state and detection of one photon by a single-photon detector. There are different conditions to quantify the entanglement of non-classical states. We compare the entanglement cond......
Content-Driven Answer Selection in Community Question Answering Using Clustering and Fuzzy Ranking
National Academy Science Letters - Tập 47 - Trang 51-54 - 2023
The main task of question answering system is retrieval of high-quality answer; to achieve that, we are utilizing string similarity approach with clustering model to retrieve similar or related questions from the dataset. But ranking similar type of question answer will not solve the problem; we also considered expert ratings of the answer and treating it as a user satisfactory index or rating; to......
Synthesis, IR Spectral Studies and Antimicrobial Studies of Some Rare Earth Metal Complexes with Meso 2,3-Dimercaptosuccinic Acid
National Academy Science Letters - Tập 35 - Trang 249-252 - 2012
Biologically active La(III), Sm(III), Gd(III) and Dy(III) complexes were synthesized by using meso 2,3-dimercaptosuccinic acid as ligand and were characterized by elemental analysis and spectral measurements. Coordination of the ligand atoms to the metal ion was deducted by IR spectral data. The in vitro antibacterial screening of the free acid and its metal complexes has been carried out against ......
A Computational Approach for Solution of Singular Boundary Value Problem with Applications in Human Physiology
National Academy Science Letters - Tập 35 - Trang 189-193 - 2012
In this paper, a numerical algorithm is developed for the approximation of the solution of nonlinear two point second order singular boundary value problems arising in human physiology. Cubic Extended B-spline (EB-spline) is employed after modification of the problem at the point of singularity by L’ hospital rule. Resulting nonlinear system of equations is solved to get the solution. This is show......
Cadmium Accumulation, Growth Performance and Antioxidant Properties of Bacterial Consortium Inoculated Mentha arvensis L. Grown in Polluted Soil
National Academy Science Letters - - Trang 1-4 - 2024
In the present study, growth performance, antioxidant activities and cadmium (Cd) accumulation in eco-friendly bacterial consortium inoculated Mentha arvensis grown in Cd contaminated soils were evaluated. Eco-friendly bacterial consortium inoculation significantly enhanced growth, biomass and antioxidant efficacy of M. arvensis plants grown in contaminated soil, i.e. wastewater irrigated and Cd-s......
