in order to investigate the effect of application methods of znso4 on qualitative, quantitative and correction of zinc deficiency in grapevine, an experiment was conducted in completely randomized block design with 10 treatments and 4 replications. treatments included control, trunk injection three levels 1.5, 3 and 5 g/l, spray in three levels 1.5, 3 and 5 g/l and soil application (soil drench...

Though most of the metallic ions are spermicidal in action, the present investigation emphasises the spermicidal activity of anions. Among the inorganic compounds screened at 4 concentrations (0.01%, 0.1%, 1% and 5%) halides are mainly spermicidal, except NaCl, KCl & CsCl which are spermiostatic; sulphates and nitrates are mainly spermiostatic except ZnSO4 at 1% concentration and above; CuSO4, ...

Vehicle emissions have become one of the most prevailing air contamination sources, including nitrogen oxides, volatile organic compounds, carbon monoxide and particulate matter (PM). Among other pollutants, PM limits visible sight distance poses health risks upon inhalation into human body. This study focused on assessing PM2.5 concentrations in at different periods day highly trafficked grade...

A novel surface-enhanced Raman scattering (SERS)-based probe to capture heavy metal ion (Zn2+) by bovine serum albumin (BSA) using Si-nanowire (SiNW) arrays with silver nanoparticles (AgNPs) was developed. layer AgNPs deposited on the SiNW surface RF magnetron sputtering for enhancement of SERS signals. Using a high-resolution transmission electron microscope (HRTEM), observation reveals that A...

that require Zn2t Zincon and the standard ZnSO4 solution were from J.T. Baker; Tris (THAM) and sodium tetraborate were Fisher Certified. The 2-amino-2methyl-1-propanol was from Sigma (pfs, lot No. 14C-3610) as were the Good’s buffers 4-morpholineethanesulfonic acid (MES) and 2-[2-hydroxy-1,1bis(hydroxymethyl)ethyl]aminoethanesulfonic acid (TES). The other Good’s buffers, N,N-bis(2-hydroxyethyl)...
