We studied vegetation attributes in Indian tropical moist deciduous unmanaged forests to determine the influence of forest disturbances on them. We enumerated 89 species: 72 under moderate disturbance and 54 under least disturbance. The data from 3399 stems [>5 cm diameter at breast height (dbh)] decreased linearly along the disturbance gradient. The basal area was largest in least disturbed forests (61 m2/ha) and smallest in intensely disturbed forest (41 m2/ha). Under least and moderate disturbance, tree density-diameter distribution had negative exponential curves, whereas highly disturbed forests had unimodal-shaped curves where a few trees 5–10 cm and >50 cm in diameter were recorded. Most tree and shrub layer species under heavy and intense disturbance had impaired regeneration. Moderate disturbance intensity thus apparently benefits species diversity, stand density, and regeneration. Decline in seedlings and saplings, especially tree species, threaten forest regeneration and the maintenance of species diversity of unmanaged tropical forests.

The periodic nature of the cardiac cycle induces a pulsatile, unsteady flow within the circulatory system. The pulsatile model of blood flow provides data to analyse the physiological situation in close proximity. The distribution of fatty cholesterol and artery-clogging blood clots in the lumen of the coronary artery is assumed as a porous medium. A mathematical model for pulsatile flow through an stenosed artery filled with porous medium in the presence of transverse static magnetic field has been formulated under the con\-sideration of hematocrit dependent viscosity of blood that governed by Einstein equation. The velocity pro\-file, volume flux, pressure gradient and wall shear stress are obtained and the effects of magnetic number, Darcy number, Womersely number are computed and represented through graphs.

In the whole world, most of the air polluted cities were normalized during the COVID-19 lockdown but after the lockdown, the air pollution is continuously increasing day by day. In the present study, we assessed the air quality at the selected sites of Jaipur city after the COVID-19 lockdown from October 2020 to February 2021 to quantify the enhancement in air pollution. The obtained data was processed using air quality index (AQI), principal component analysis (PCA) and pearson correlation matric (PCM). The obtained data were also compared with National Ambient Air Quality Standards (NAAQS). Values of particulate matter ( PM10, PM2.5) were found beyond the limits of NAAQS (100 μg/m3, 60 μg/m3) while the values of gaseous pollutant such as SO2, NO2, and CO was found below the limits of NAAQS (80 μg/m3, 80 μg/m3, 4.0 mg/m3). Based on AQI, air quality of site 1 (114.80) and site 2 (110.48) was found severely polluted while air quality of site 3 (70.47) was found moderately polluted. Based on PCA, the highest loading factor was declared to PM10 and the lowest loading factor was SO2. The study concludes that by adopting the control measures of particulate matter and periodical transport lockdown, air pollution can be minimised.
Statistical Optimization of Physical Parameters for Enhanced Bacteriocin Production by L. casei

Antimicrobial proteinaceous compounds such as bacteriocins produced from Lactobacillus sp. are widely known. They have potential antimicrobial activities towards closely related bacteria and several pathogens associated with food spoilage and hence can be a potential food bio-preservative agent. Bacteriocin production requires optimized process, complex media and well-controlled physical conditions including pH and temperature. A probiotic strain of L. casei LA-1 isolated from mango pickle was used in the present study. The influence of physical parameters viz. temperature (15 ~ 45oC), pH (4.0 ~7.0), incubation time (up to 48 h) and inoculum size (0.7 ~2.0 O.D) on bacteriocin production was analyzed. The effect of all the parameters was first investigated using the one-factor-at-a-time method (OFAT) to see the significance of these parameters on bacteriocin production and then further optimized by response surface methodology (RSM). Following OFAT analysis, all factors were found to have a significant effect on bacteriocin production. Bacteriocin production of 2,844 AU/mL was obtained at temperature 37oC, pH 6.7 and inoculum size 1.8 O.D at an incubation time of 20 h and it was produced during the stationary phase of growth. Statistical analysis showed that three variables-pH, temperature and incubation time have significant effects on bacteriocin production. RSM proved to be a powerful tool in the optimization of bacteriocin production by L. casei LA-1 with a two-fold increase,giving a production of 4652.15 AU/mL at pH 7.19, temperature 33.3oC and incubation time of 22.2 h.

The induced current (fraction of the wall current) flowing through a strip is a very crucial quantity in stripline-type pick-ups and kickers. Quantities like the output voltage, coupling impedance and kicker constant depend on the fraction of the wall current flowing through the strip. Due to the fringe field at the side edges of the strip the effective angular width of the strip and, hence, the fraction of the wall current intercepted by the strip is enhanced. This paper presents a calculation, by using CST EM studio, of the fraction of the wall current intercepted by the strip. A correction factor for the effect of the fringe field on the current induced in the strip is also presented. The results obtained through simulations and through a new expression are compared with earlier existing expressions.
