The process is mild and inexpensive; the yields are high and the reactions go to completion within 2-7 min. © 2012 Elsevier B.V. All rights reserved

Emergency Detection and Monitoring Daily Routine of a Cattle using IOT

The main aim of this system is to smarten the infrastructure of cattle farming and to track the biological and physiological activities of cattle by implementing a noninvasive wearable by using IOT. In these, we come into picture the lightning sensor depend upon the climate it will turn on and off, temperature sensor will depend upon room temperature of cattle farm; methane sensor is used to check methane level in the farm; fire sensor depend upon any fire emergency and is responsible for smart lighting and also smart ventilation, it is also responsible for sprinkler actuation to make the infrastructure safer and smarter. We are also implementing automatic food releasing mechanism. We can identify the single cattle count with the help of the IR sensor

Synthesis and characterization of Schiff base analogues of fluoroaniline and their antibiocidal activity against MRSA

A group of new fluoroaniline Schiff bases (3a–3f) were synthesized and structurally characterized by various spectroscopic techniques such as 1H-NMR, LC-MS and FT-IR spectral studies. All compounds were evaluated for in vitro antibacterial activity. Compounds exhibited good to moderate antibacterial activity. Compound 3f (Zone of Inhibition = 10.08±0.06 µM) was found to be the most active one, and comparable to the standard Streptomycin (IC50 = 15.95±0.08 µM). The compounds having chloro substituent exhibit good membrane damage property against Methicillin-resistant Staphylococcus aureus (MRSA) confirmed by SEM analysis. Structure-activity relationship (SAR) was rationalized by looking at the varying structural features of the molecules

Baeyer Condensation: A Facile Synthesis of Triarylmethanes Using Atomized Sodium in THF under Sonic Condition

A simple and an efficient procedure for a one - pot three - component condensation of substituted aldehydes and N,N - dimethylaniline into corresponding triarylmethanes by atomized sodium in THF under ultrasonic condition is developed. The new protocol for the Baeyer condensation under sonic condition works with commercially available precursors and an economically viable catalyst , involves simple work - up, gives high yields of the products and the reactions go to completion within 2 – 5 mins

Synthesis, Characterization, and Antimicrobial Activity of Methyl-2-aminopyridine-4-carboxylate Derivatives

A series of methyl-2-aminopyridine-4-carboxylate derivatives, 3a–f, were synthesized in order to determine their in vitro antimicrobial activity. The chemical structures of the synthesized compounds were confirmed by elemental analyses, FT-IR, and 1H NMR spectral studies. Among the synthesized compounds, 3c and 3d showed good antimicrobial activity compared to other compounds in the series

Synthesis and characterization and X-ray/gamma ray absorption properties of tin oxide synthesized via solution combustion method

Tin oxide (SnO2) nanoparticles (NPs) are synthesized via solution combustion method using Glycine as a fuel followed by the calcination and characterization. The Bragg reflections clearly confirms the formation of tetragonal rutile phase with crystallite size 10 nm. The irregular shaped agglomerated NPs are observed on the surface morphology. The energy band gap was determined (3.7 eV). Theoretically, mass attenuation coefficient is determined which is an essential data required in diverse fields

Study of normal anatomy and variations in gall bladder

Background: The extra hepatic biliary apparatus consists of right and left hepatic ducts, common hepatic duct, gall bladder, cystic duct and common bile duct which collects and delivers the bile from liver to second part of duodenum. Anatomical variations of biliary tree occur with sufficient frequency to be of concern to the surgeons operating in this area. Identification of anatomical details is necessary for accurate detailing of biliary tree to avoid inadvertent damage to biliary ductal system. Objective: To study the normal anatomy and variations of gall bladder by dissection method. Methods: In the present study a total number of 50 adult human livers with lesser Omentum, duodenum and pancreas were collected from the dissected cadavers from the department of anatomy KVG Medical College Sullia and Chamarajanagar institute of medical sciences, Chamarajanagar. The various parameters of the gall bladder and biliary ductal system were recorded and photographed. Observations and results: The following variations were observed in the present study. Hartmann’s pouch was observed in 42% (21/50).  Hourglass GB was observed in 2% (1/50).  Folded fundus was observed in 2% (1/50). Intrahepatic GB was observed in 4%.&nbsp

Schiff bases of 4-(methylthio)benzaldehydes: Synthesis,characterization, antibacterial, antioxidant and cytotoxicity Studies

A series of new Schiff bases of 4-(methylthio)benzaldehyde derivatives 3(a-i) were synthesized by the reaction of 4-(methylthio)benzaldehyde with various amines 2(a-i). Newly synthesized compounds were characterized by elemental analyses, UV-visible, FT-IR, Mass and 1H NMR spectral studies. All compounds were evaluated for their in vitro antibacterial activity against clinically isolated strains i.e., E. Coli, P. Fluorescence, M. Luteus and B. Subtilis. These compounds were screened for their antioxidant activity by 2,2-diphenyl-1-picryl-hydrazyl (DPPH•) and ferrous ion chelating assay (Fe2+) methods. The cytotoxicity assay was performed by tryphan blue dye exclusion method. Compounds 3g, 3h and 3i exhibited good antibacterial activity when compared with other compounds in the series against tested pathogenic bacterial strains. All the compounds showed antioxidant activity, where compound 3b was the best radical scavenger and Fe2+ ion scavenger. These findings showed that the Schiff bases of 4-(methylthio)benzaldehyde derivatives possess antioxidant activity with different mechanism of actions towards the different free radicals tested. Among these derivatives, 3b and 3h had the strongest activity against human peripheral lymphocytes
