New series of bidentate ligands such as dithocarbamates of 2-Amino-3-Methyl pyridine (2A3MPDTC) and 2- Amino-4-Methyl pyridine (2A4MPDTC) were prepared by new synthetic methods as their sodium salts. In the reaction of Copper Chloride and Cobalt Chloride with 2A3MPDTC and 2A4MPDTC the corresponding complexes were prepared. The complexes were characterized by elemental analysis, IR, 1H NMR, UV, ESR and TGA - DTA. These metal complexes play a good activity against E. coli and Basillus subtilis. The investigations revealed that the complexes are better anti-bacterial agents than the Ligands.Keywords

Fipronil is a broadspectrum N-phenylpyrazole insecticide with gamma-aminobutyric acid type A receptor inhibitory action causing hyperexcitability of central nervous system. There is no literature reported in the past concerning its acute toxicity in human beings. A case report is useful for workers in medical and veterinary field. Hence, we are reporting a case in which young male intoxicated with fipronil compound was presented to the emergency department for having generalized tonic-clonic seizures and subsequently with the features of delirium for few days. This patient was treated with benzodiazepines which controlled the seizures and antipsychotics were given for few days for treating the psychosis.Keywords

In an earlier paper from this laboratory studies carried out to determine the extraction of protein from blackgram seeds under various parameters like successive extraction with different extractants, particle size, ratio of sample to solvent, pH and temperature have been reported. It has been reported that germinated pulses are a good source of vitamin C. Blackgram seed is a rich source of lysine (7'36 g/16g N). As a follow-up of the earlier work it was of interest to study the vitamin C and available lysine contents of the seeds germinated for different periods of time.- Sustainable Units for Structural Masonry

Background/Objectives: To determine the basic properties of masonry units, modulus of elasticity and to evaluate the masonry efficiency for the different h/t ratios of the masonry prisms and wallets. Methods/Statistical analysis: The geopolymer blocks were cured in open air temperature. These blocks were tested for water absorption & initial rate of water absorption, dry density, dimensionality, compression strength, flexural strength, and bond-strength with & without lateral confinement and modulus of elasticity. Rendered and unrendered geopolymer solid block and hollow prisms were cast and tested using cement mortar for the different h/t ratios and wallets were tested for compression. Findings: It was found that the basic properties of geopolymer masonry units were well within the limits prescribed the relevant codes of practice. Flexural strength and bond strength of geopolymer blocks prisms was more due to the good bonding between the blocks and the mortar joints. The masonry efficiency is increases with decrease in h/t ratios. There will be no much difference between rendered and unrendered masonry efficiency block prisms. The performance of the axial and eccentrically loaded wallette was found to be superior compared to the conventional cement block masonry. They satisfy the requirements of IS 2185:2008 (part 4). Application/Improvements: These geopolymer masonry units were used as structural masonry units due to the good compressive strength and performance.Keywords

Background/Objectives: To determine the basic properties of masonry units, masonry efficiency for the different h/t ratios of the masonry prisms and wallets. Methods/Statistical Analysis: The geopolymer bricks were cured at ambient temperature. These bricks were tested for compression, Initial Rate of Absorption [IRA], density, water absorption, dimensionality and modulus of elasticity. They were also tested for alternative drying and wetting. The microstructure of the bricks was also analyzed. Geopolymer prisms were cast and tested using geopolymer mortar / cement mortar for the different thickness of joints. The Masonry wallets were constructed using geopolymer brick and conventional cement mortar. They were tested for axial and eccentric loading. Findings: The compressive strength of geopolymer brick attains more than 5MPa within 24 hours which influences the user to handle without any issues. It was found that the basic properties of geopolymer masonry brick well within the limits prescribed in the relevant codes. Geopolymer mortar can be used as mortar in building masonry structures as it exhibits better compressive strength and other properties than cement mortar. The performance of the axial and eccentrically loaded wallette was found to be superior compared to the conventional cement brick masonry. Application/Improvements: The geopolymer masonry bricks were used as structural masonry units due to better performance.Keywords

The MACE telescope has recently been commissioned at Hanle, Ladakh, India. It had its first light in April 2021 with a successful detection of very high energy gamma-ray photons from the standard candle Crab Nebula. Equipped with a large light collector of 21 m diameter and situated at an altitude of ~4.3 km amsl, the MACE telescope is expected to explore the mysteries of the non-thermal Universe in the energy range above 20 GeV with very high sensitivity. It can also play an important role in carrying out multi-messenger astronomy in India.Keywords
