ExoMars Schiaparelli Direct-to-Earth Observation using GMRT

During the ExoMars Schiaparelli separation event on 16 October 2016 and Entry, Descent, and Landing (EDL) events 3 days later, the Giant Metrewave Radio Telescope (GMRT) near Pune, India, was used to directly observe UHF transmissions from the Schiaparelli lander as they arrive at Earth. The Doppler shift of the carrier frequency was measured and used as a diagnostic to identify key events during EDL. This signal detection at GMRT was the only real‐time aliveness indicator to European Space Agency mission operations during the critical EDL stage of the mission

Effect of major nutrients on yield of ginger (Zingiber officinale Rose.) intercropped in coconut garden

The effect of different levels of nitrogen, phosphorus and potassium on the yield of ginger (Zingiber officinale Rosc.) grown as an intercrop in a coconut garden was studied in a field experiment conducted at Coconut Research Station, Balaramapuram, Thiruvanathapuram, Kerala. Significant increases in leaf production, leaf area index and dry matter production, crop growth rate and uptake of nutrients were resulted from higher dose of fertilizers. Fertilizer recommendation for ginger grown under open condition (N:P:K @.75:50:50 kg ha-1) is insufficient for ginger intercropped in coconut gardens. A higher fertilizer dose of N:P:K @ 150:100:100 kg ha-1 is necessary for increasing the yield of ginger grown as an intercrop in coconut garden. &nbsp

Influence of shade regimes on yield and quality of ginger (Zingiber officinale Rosc.)

The effect of different levels of shade on yield and quality of ginger (Zingiber officinale Rosc.) was studied during two seasons at Coconut Research Station, Thiruvananthapuram, Kerala Agricultural University, Kerala. The shade levels 20 and 40 per cent were favourable for obtaining higher dry ginger yield. Volatile oil content showed an increasing trend with increasing levels of shade. Maximum NVEE was recorded in the plants grown under 20 and 40 per cent shade levels. Higher starch content was observed in plants grown under 20 per cent shade level. Crude fibre content gradually reduced as the intensity of shade increased. The results indicate the possibility of utilizing existing shaded situations in coconut gardens and under other perennial crops for the production of ginger. &nbsp

DEVELOPMENT AND VALIDATION OF A MODIFIED POLARIMETRIC ASSAY METHOD FOR SMALL VOLUME SAMPLES

Objective: The objective of the present work was to develop a method to be useful for analyzing small volume samples of an optically active compound.Methods: The method employed quartz cuvette instead of a polarimeter tube. Quantification of optically active compound was successfully validated in terms of linearity and range, precision and robustness. The detection limit (DL) and quantitation limit (QL) were determined as per the ICH guidelines.Results: Polarimetry generally involves the quantification of optically active compounds by measuring its ability to rotate (in terms of angle of rotation) polarized light passed through it. The plot of angle of rotation versus concentration was linear in wide range of concentration with excellent coefficient of determination of 0.9989±0.0008. The low values of % relative standard deviation (RSD) for repeatability and intermediate precision suggested an excellent precision of the developed polarimetric method. The detection limit (DL) and quantitation limit (QL) were determined were found to be 0.5025 and 1.5225 %w/v respectively.Conclusion: A modified polarimetric method for the quantification of dextrose was successfully developed and validated. The method employed quartz cuvette instead of polarimeter tube. The method is expected to be useful in a variety of industries where dextrose finds its application. The method can also be extended to other optically active compounds

A PREFORMULATION STUDY ON INTERACTIONS BETWEEN DOXORUBICIN HYDROCHLORIDE AND BOVINE SERUM ALBUMIN

Objective: The objective was to study the effect of concentrations of doxorubicin hydrochloride (Dox) and bovine serum albumin (BSA) in a sample on fluorescence intensity, UV absorbance, refractive index and optical rotation.Methods: A circumscribed central composite statistical design with 2 factors, 5 levels, and 13 runs was selected for the study. According to that influence of both in interaction was measured by fluorescence intensity, UV absorbance, refractive index and optical rotation and were analyzed by the design expert software.Results: It was observed that concentration of BSA alone was significantly affecting the fluorescence intensity and optical rotation of samples. Dox alone was having a significant effect on UV absorbance at 280 nm. In the case of a refractive index, both Dox and BSA were having a significant effect. But the effect of BSA was much pronounced than that of Dox on refractive index.Conclusion: Interaction studies between BSA and Dox would be beneficial as they are commonly used in combination with tumor-targeted delivery. The interaction was observed that in a linear model for a wide range of concentration of both. So it will be useful to determine the interaction of unknown concentration

Elephant (Field Based) in Natrinai Song

Human life requires language. Without language there is no human life. Civilization and one-to-one communication occurs through language. Man expresses thought through language. Poets have expressed their eloquence and depth of language through song. Because of this, it is necessary to carry out studies on the words they say nowadays. A word in Tamil has not only one meaning but also many meanings. There are no words without meaning. In the Sangam literature, among the eighteen above mentioned texts, the Naritana is placed as the first deposit. This article deals with the etymological analysis of the word 'Elephant' in the narrative songs

Aspirin Therapy In Neurological Disorder Such As Migraine And Alzhemeirs Disease

Aspirin, a widely used nonsteroidal anti-inflammatory medication, has a long history of therapeutic applications in pain relief, fever reduction, and inflammation management. Recent research has expanded its potential utility in treating neurological conditions such as migraines and Alzheimer's disease. For migraine management, aspirin's mechanism of action involves the suppressing the production of prostaglandins, a key factor in migraine-related inflammation and pain. Clinical trials have demonstrated its effectiveness in reducing the intensity and frequency of migraine attacks. Aspirin, especially when combined with metoclopramide, has proven to be a valuable treatment option for acute migraine episodes. In the case of Alzheimer's disease, which exhibits neurodegeneration, aspirin's anti-inflammatory and antioxidant properties have generated interest in its potential as a preventive and therapeutic agent. While epidemiological studies and biological processes have suggested aspirin's potential benefits, randomized studies have raised concerns about the risks of bleeding, outweighing the potential advantages. This review article examines the latest research on aspirin's role in managing and preventing migraines and Alzheimer's disease. It also discusses the clinical research regarding aspirin's effectiveness, safety profile, and possible side effects in these neurological conditions. Finally, the article explores the directions for future research involving aspirin in relation to migraines and Alzheimer's disease
