Aim: To study the effect of weather variables in development sheath blight rice. Methodology: The nursery rice cv. PR 121 was raised last week May four consecutive kharif seasons 2019 to 2022 and one-month-old seedlings were transplanted field. disease assessed using a 0-9 rating scale at appearance first symptoms correlated with viz., maximum temperature (Tmax), minimum (Tmin), relative humidity morning (RHm), evening (RHe), rainfall (RF) sunshine hours (SS). multiple linear regression...
Nickel(II) tetraisopropoxyaluminate undergoes alcoholysis reactions with various alcohols and acetylacetone to yield products the composition: Ni[Al(OR) 4 ] 2 (when ROH = methanol, ethanol, 2,2,2-trifluoroethanol, 2,2,2-trichloroethanol, n-butanol, 1,3-dichloro-2-propanol); Ni[Al(O-i-Pr)(O-t-Bu) 3 (with tertiary butyl alcohol); Ni[Al(O-i-Pr) (O-t-Am) amyl (acac) acetylacetone). On basis of their visible reflectance infrared spectra along molecular weights magnetic susceptibilities,...
The operational global spectral model of the National Center for Medium Range Weather Forecasting (NCMRWF) at T80 resolution and 18 vertical levels has been used to study skill medium-range forecasts using three different parameterizations deep convection namely, a Kuo–Anthes-type cumulus parameterization scheme referred as “KUO” scheme, relaxed Arakawa–Schubert (RAS) simplified (SAS) during an active phase Indian summer monsoon. Several (up 5 days) have made initial conditions July August...

Aim: To evaluate and compare the antibacterial efficacy of Melaleuca alternifolia (tea tree oil), Curcumalonga (turmeric), 2% chlorhexidine (CHX), 5% sodium hypochlorite (NaOCl) against Enterococcus faecalis. Materials Methods: Agar plates were prepared using tryptone soya agar. Cultures E. faecalis grown in broth. well diffusion method was performed incubated at 37C for 24 h. The zones inhibition recorded. readings subjected to statistical analysis variance (ANOVA) Tukey's post hoc test....
N-substituted pyridine hydrazide (pyridine-2-carbonyl chloride and 4-chloro-benzoic acid hydrazide) undergoes formation of the iminic carbon nitrogen double bond through its reaction with cobalt(II), nickel(II), copper(II) metal salts in ethanol which are reported characterized based on elemental analyses, IR, solid reflectance, magnetic moment, molar conductance, thermal analysis (TG). From analyses data, 1 : 2 complexes formed having general formulae [MCl (HL) ] · y H O (where M = Co(II),...
The association of lightning flashes with mean cloud ice size over continental and oceanic region in the tropical areas has been analyzed using observations from various satellite platforms (MODIS, TRMM, LIS) for period 2000–2011. We found that frequency general is higher compared to region, whereas larger observed regions regions. Relationship between lighting shows similar features both For first time, we show total increases increase size; attends maximum at certain then decreases size....
A practical synthesis of 2-carboxyphenylboronic from 2-tolylboronic acid and aqueous potassium permanganate under mild conditions is reported. The title compound couples with aryl bromides containing electron-withdrawing groups to give biaryl-2-carboxylic acids.
Cobalt(II), Nickel(II), Copper(II) and Manganese(II) complexes, having the general composition {M(L) 2 X }, have been synthesized [where L= bis(pyridine‐2‐carbo) hydrazide(L), = Cl – ]. All Metal complexes reported here characterized by elemental analysis, molar conductance, magnetic moments, IR, electronic mass spectral studies. were found to moments corresponding unpaired electrons. The possible geometries of assigned on basis infrared On conductance values show 1:2 electrolytic nature....
