Optical and electrical properties of a new polymer
( John Wiley & Sons, Inc. , 1997 , Article)
Thin film of poly (5-isopropylidenecyclo-1,4-vinylene-2,3-dicarboxylicacidamide-s-methyl hydrazinecarbodithioate) (II) (Scheme 1) of 5 ?m thickness was prepared. The dielectric properties of the prepared sample were studied ...
Effects of substituting fish meal with Azolla pinnata in practical diets for fingerling and adult Nile tilapia, Oreochromis niloticus (L.)
( Blackwell Publishing Ltd , 1992 , Article)
Dry and fresh Azolla pinnata were evaluated as feed ingredients for fingerling and adult Nile tilapia, Oreochromis niloticus (L.). Dry Azolla was incorporated into practical diets containing approximately 30% crude protein ...
Use of Mathcad as a teaching and learning tool for reinforced concrete design of footings
( John Wiley & Sons, Inc. , 1999 , Article)
Owing to their nature, numerous and complex equations are commonly used in the design of reinforced concrete structures. This is because of the nature of reinforced concrete design. Mathcad, which possesses efficient ...
Photosynthetic acclimation to high temperatures in wheat
( John Wiley & Sons, Ltd. , 1992 , Article)
Growth and photosynthetic performance were assessed for the Finnish wheat Triticum aestivum L. var. APU under a cool (13/10�C day/night) and a warm (30/25�C day/night) regime. Plants exhibited a certain degree of acclimation ...
Water stress and gibberellic acid effects on growth of fenugreek plants
( Springer Berlin / Heidelberg , 1998 , Article)
Fenugreek plant is susceptible to water stress during the vegetative growth stages, since a soil matric potential lower than -0.3 MPa causes substantial reduction in growth parameters such as height, weight and total leaf ...

Ultrasonic and thermal properties of γ-irradiated low-density polyethylene
( John Wiley & Sons, Inc. , 1993 , Article)
The ultrasonic pulse-echo technique and differential thermal analysis were utilized to characterize and to monitor the effect of ?-irradiation on the sonic modulus and the heat effect of low-density polyethylene. The sonic ...
Kinetics and mechanism of H2O2 decomposition by Cu(II)-, Co(II)-, and Fe(III)-Amine complexes on the surface of Silica-Alumina (25% Al2O3)
( John Wiley & Sons, Inc. , 1994 , Article)
The kinetics of the H2O2 decomposition by Cu(II)-, Co(II)-, and Fe(III)-amine complexes supported on the surface of silica-alumina (25% Al2O3) catalyst have been investigated. The decomposition process proceeded with ...
Purification and characterization of an extracellular phenol oxidase from culture filtrates of Pyricularia oryzae
( NRC Research Press , 1996 , Article)
Extracellular phenol oxidase activity was characterized and compared in Pyricularia oryzae wild-type and albino cell types to determine if this phenol oxidase was responsible for lack of melanization in the albino culture. ...
