Distance learning presents great potential for mitigating field problems on pesticide application technology. Thus, due to the lack of teaching material about pesticide spraying technology in the Portuguese language and the increasing availability of distance learning, this study developed and evaluated a computer program for distance learning about the theory of pesticide spraying technology u...

Introduction Iodine and iodinated resin have been evaluated for water treatment. Iodine (2.5-7.0 mg/l water) has been used in water treatment since 1900, especially for troops. Iodine’s solubility in water depends on temperature (0.29 g/1 at 20°C, 0.78 g/l at 50°C and 4.45 g/1 at 100°C). Its hydrolysis and hence speciation in water depends on pH and concentration of titrable iodine in solution....

The water spray systems are effective protection systems in the confined or unconfined spaces to avoid the damage to building structures since the high temperature when fires occur. NFPA 15 and 502 have suggested respectively that the factories or vehicle tunnels install water spray systems to protect the machinery and structures. This study discussed the cooling effect of water spray systems i...

Phosphoenolpyruvate carboxylase (PEPCase), the key enzyme of Crassulacean acid metabolism, is induced by water stress in leaves of Mesembryanthemum crystallinum. In water-stressed plants or excised leaves, exogenous cytokinin suppresses PEPCase transcript accumulation in the leaves. Cytokinin (6-benzylaminopurine) used in concentrations from 5 to 500 micromolar (a) inhibits the upregulation of ...

to determine the effects of drought stress and fe and zn spraying on two annual medics, namely, medicago polymorph cv serena and medicago scutellata cv comertial, a field experiment as a split factorial based on a randomized complete blockdesign in 3 replications in allborze agricultural research center, in karaj was conducted. spraying treatments include distilled water (control), fe, zn and f...
