Lodging is a phenomenon that affects most of the cereal crops including rice, Oryza sativa. This is due to the fragile nature of herbaceous plants whose stems are non-woody, thus affecting its ability to grow upright. Silicon (Si), a beneficial nutrient is often used to toughen and protect plants from biotic and abiotic stresses. Deposition of Si in plant tissues enhances the rigidity and stiff...

AIMS To determine if exposure to dimethylisopropanolamine (DMIPA) and dimethylaminoethanol (DMAE) in a label printing plant was associated with visual disturbances and/or ocular changes. METHODS Questionnaires, eye examinations (visual acuity, contrast sensitivity at 2.5% and 1.25% contrast, slit lamp biomicroscopy, and pachymetry), and industrial hygiene monitoring for DMIPA and DMAE were pe...

佐久間 昭 * Present Address : Department of Pharmacology , Institute for Cardiovascular Diseases, Tokyo Medi cal & Dental University, Bunkyu-ku, Tokyo. Ftc. 1. In autoperfusion of dog hindquarters, distal electro stimulation (E) of the divided lumbar sympathetic chains and i.a. DMPP (D) are serially challenged by fl-TM 10, tripelennamine (PBZ) and atropine (Atr). Intraarterial injection of 20 to 10...

BACKGROUND Galvanization is the process of coating steel or cast iron pieces with a thin layer of zinc allowing protection against corrosion. One of the important hazards in this industry is exposure to zinc compounds specially zinc oxide fumes and dusts. In this study, we evaluated chronic effects of zinc oxide on the respiratory tract of galvanizers. METHODS Overall, 188 workers were select...

Heteroatom-doped porous carbon materials are highly desired for supercapacitors. Herein, we report the preparation of such material from polybenzoxazine (PBZ), a kind phenolic resin. Four different N- and O-codoped microporous were obtained by changing carbonization temperature (600, 700, 800, 900 °C). Their structures characterized scanning electron microscopy (SEM), nitrogen isothermal absorp...

In the present study, two magnolol based main chain benzoxazine polymers (MCBPs) are designed, synthesized and formulated into thiol-ene resins to develop high-performance polymer dielectrics. Initially, thermoset films, Mag-M-4SH-80 Mag-E-4SH-80, obtained respectively using click chemistry. Being post cured via progressive temperature stage, Mag-M/E-4SH-80 performs complete ring opening polyme...

Scrutinizing of different aspects in vegetative propagation of Iranian J. communis L. is of prime importance in order to prevent extinction of such valuable conifer. In this research, the effects of different seasons, gender, different chemical compounds (IBA, PBZ, putrescine and sodium nitroprusside) and three strains of Agrobacterium rhizogenes on ex-vitro rooting c...
