Based on this fundamental concept, the study area has been chosen for the documentation of plant species in north Coimbatore city area to accomplish the project. The planned study area comprises of Periyanaicken palayam, Annur, Karamadai, Sarcarsamakulam. There are hundred plant species documented in this floristic study. Out of which 62 are domesticated plants as ornamental or other consumption purposes and 37 are wild plants around the residing area. This analysis indicated that the documented plant species comes under 40 taxonomic families. Highest species found in the family Fabaceae (15), Apocyanaceae (7), Solanaceae (5), Malvaceae (5), Acanthaceae (5). It is also revealed that the documented domesticated plant species are with the high number of Tree habits (40%) whereas documented wild plant species are with the high number of Herb habits (46%) than other habits. Among which most of the plants are used for domestic consumption, ornamentation and few are medicine. In this survey, no rare status plants have been observed and the area is completely civilized and the land area around the residence has been highly influenced by human beings. The wild species documented in this area are herbaceous weed plants blooming at every rainy season. This study concluded that the wild plants are highly destroyed for various purposes and lead to have only herbaceous weeds around us. Hence the cultivation of trees and protection management has to be initiated to increase the green cover of the study area to regain the misty, moderate climate as the identity of Coimbatore. It will definitely improve the wild fauna lives of the area and other ecological services from vegetation.</p> 2022-06-30T00:00:00+00:00 Copyright (c) https://krjournal.com/index.php/krj/article/view/538 Changes in polyphenolic contents and antioxidant potential of the leafy vegetable, talinum portulacifolium by moist heat cooking 2022-08-06T10:49:52+00:00 Syed Ali Akbar S I asfsa@gmail.com Aiswarya K asfsa@gmail.com Logasri B asfsa@gmail.com Sowndhararajan K asfsa@gmail.com <p>In general, most of green leafy vegetables undergo a cooking process prior to consumption.

Detection of disorders related to potassium levels including hyperkalemia and hypokalemia is very much challenging in the current scenario. Potassium imbalance leads to massive change in electrical activity of the body especially disturbs the function of the brain, heart, nerves, bone and muscles in hospitalized patients. Potassium loss is a major concern in disorders such as hyperhidrosis and Cystic Fibrosis. Hence the real-time monitoring of potassium levels in the hospitalized patients may provide information related to latent cardiac problems and also assist in the diagnosis of apparent life-threatening diseases. Comprehensively, the real-time monitoring of potassium concentrations may shed light on the electrolyte loss, dehydration status and also the other associated diseases. In this study, the correlation between the electrocardiogram (ECG) signals and the potassium levels can diagnose the potassium imbalance in a non-invasive manner. The novelty of our work is to develop a wearable E-textile integrated sensor for the detection of hyperkalemia and hypokalemia through ECG signal. The main advantage of this product is wearable and portable, and also ensures the patient safety and user friendly particularly for elderly and disabled patients and also for children.</p> 2022-06-30T00:00:00+00:00 Copyright (c) https://krjournal.com/index.php/krj/article/view/540 Antibacterial study of ZnO and Zn0.5Mg0.5O nanoparticles synthesized by co-precipitation method 2022-08-06T10:52:29+00:00 Swathi T asfsa@gmail.com Nithya V D asfsa@gmail.com <p>In the present study, zinc oxide (ZnO) and magnesium doped zinc oxide (Zn<sub>0.5</sub>Mg<sub>0.5</sub>O) nanoparticles were synthesized by simple and cost-effective co-precipitation method. The synthesized materials were characterized by X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR) spectroscopy, Field Emission Scanning Electron Microscopy (FESEM) with Energy dispersive X-ray spectrum (EDAX). Finally, the effect of magnesium (Mg) doping on the structural, morphological and anti-bacterial property of ZnO nanoparticles was analyzed. From the XRD results, it was found that there was a formation of hexagonal structured ZnO and the average crystallite size of ZnO and Zn0.5Mg0.5O was calculated to be 71 nm and 36 nm respectively. The FTIR analysis confirmed the existence of possible functional groups in ZnO and Zn<sub>0.5</sub>Mg<sub>0.5</sub>O. There was formation of almost spherical shaped particles as evident from FESEM images and agglomeration of particles was observed upon doping Mg into ZnO. The EDAX spectra of the prepared nanoparticles provided the composition of Zn, O in ZnO and Zn, Mg, O in Zn<sub>0.5</sub>Mg<sub>0.5</sub>O. No other elements have been found in the EDAX spectra of ZnO and Zn<sub>0.5</sub>Mg<sub>0.5</sub>O that confirmed the formation of pure materials. Finally the anti-bacterial study demonstrated that ZnO and Zn<sub>0.5</sub>Mg<sub>0.5</sub>O was effective in inhibiting <em>E. coli</em> bacteria.</p> 2022-06-30T00:00:00+00:00 Copyright (c) https://krjournal.com/index.php/krj/article/view/541 Isolation and screening of keratinse producing bacteria from chicken farm bed 2022-08-06T10:53:23+00:00 Amrin A asfsa@gmail.com Anbarasi G asfsa@gmail.com Vishnupriya B asfsa@gmail.com Karthikeyan G asfsa@gmail.com Mahavigneshwari P asfsa@gmail.com Dharani V asfsa@gmail.com Sowndarya V asfsa@gmail.com Abdul Razzak, M I asfsa@gmail.com Vigneshwaran K asfsa@gmail.com <p>Currently, there are about 195 nations in the world, with a population of 7.8 billion. This much higher the population directly influences higher food demand. Due to this interlink massive amount of food waste has been collected from the meat industries; especially poultry plays a major role by discharging feathers into dumps. There are about 8.5 billion tons of feathers that are wasted every year which lead to high global environmental risk and cause different human disease. This high risk is due to typical structure of feather. They have a matrix protein called keratin that makes degradation more tedious under normal condition; they are insoluble in nature with high rigidity due to the disulfide bridges. By extraction of keratin from these waste feathers are used for multipurpose such as cosmetics, biomedical, textile use, bio-fertilizers etc. In addition, as per trend by utilizing nature’s gift the microorganisms we can breakdown these matrix proteins easily. By this environmental friendly technique our works gets easier and are also cost effective. By consumption of keratin as substrate some microorganisms produce an extracellular enzyme called keratinase which has the ability to cleave the protein. The produced keratinase is a wealth out of waste which has wide biochemical properties and also used for waste water treatments. On whole the feather considers as waste is completely turned to verity of useful products ubiquitous like biodiesel, biofertilizer, biodegradable plastics, biofilms, skin, hair and other biomedical treatments.</p> 2022-06-30T00:00:00+00:00 Copyright (c)
