the present study was carried out to investigate micropropagation possibility and determine the optimal medium composition and plant growth regulators (pgrs) combinations under in vitro conditions. the cotyledon and epicotyl explants obtained from 1 month old in vitro grown seedlings were used in ms medium containing ba (0.1, 0.2, 0.5, 1, 2 and 3 mg-1) and tdz (0.1, 0.2, 0.5, 1, 2 and 3 mg-1) e...

Difunctional boron-containing reactive flame retardant for UV-curable epoxy acrylate oligomer was synthesized from phenyl boronic acid and glycidyl methacrylate. The synthesized reactive diluent was utilized to formulate ultraviolet (UV)-curable wood coatings. The weight fractions of reactive diluent in coatings formulation was varied from 5 to 25 wt % with constant photoinitiator concentration...

Ammonium-based fire retardants are important in managing wildfires, but their use can adversely affect water quality. Their entry, fate, and impact were studied in five forest streams. Initial retardant concentrations in water approached levels which could damage fish, but no distressed fish were found. Concentrations decreased sharply with time after application and distance downstream, and th...

ABSTRACT Flame retardants are efficient in fighting wildfire; however, their environmental implications, especially regarding the vegetation, need to be clarified. This work aimed at assessing effects of flame retardant on initial growth Schizolobium amazonicum. Treatments consisted applying different concentrations via substrate and leaf: Phos-Chek WD-881® (0, 3.00, 6.00, 8.00 10.00 mL L-1), H...

individual grain weight of wheat kernels differs with their positions on a spike. cultivation practices (such as fertilizer nitrogen and plant growth regulators application) can be used to improve weight of basal and distal kernels. for this purpose, two experiments based on randomized complete block design were carried out with three replications. the aim of this research was to study the mech...

A new synergetic flame retardant system (SFRS) using ammonium polyphosphate/melamine cyanurate (APP/MCA) core-shell particle was synthesized and applied to papermaking. Cationic polyacrylamide (CPAM) was added to improve the adsorption of SFRS in pulp. Higher amounts of SFRS led to higher adsorption by pulp. Handsheets were produced with different amounts of SFRS. Thermal gravimetric analysis (...
