Cereal Chem. 73(5):605-612 Wheat grain was spiked with five levels of three grain protectant mixtures, aged, then milled and further processed into a wide range of end products including seven types of bread and noodles. Enzyme-immunoassay methods for quantitation of residues of three organophosphate (fenitrothion, chlorpyrifos-methyl, and pirimphos-methyl), two synthetic pyrethroid (bioresmeth...

Rhyzopertha dominica is one of the most damaging insect pests in grain elevators and causes millions of dollars worth of stored grain losses annually in the USA. A simulation model was developed for predicting R. dominica population dynamics in concrete grain bins. The model used a two-dimensional representation of a cylindrical concrete bin (33m tall 6.4m wide), and used hourly weather data to...

Dalam penelitian ini dibahas model matematis penyebaran penyakit kuning pada tanaman terong dengan protectant. Kami berasumsi bahwa protectant menggunkan ekstrak nabati daun pukul empat dapat meningkatkan sistem imun muda. menunjukkan nilai Basic Reproduction Number (BRN) dari transmisi tanaman. BRN dihitung eigen terbesar Next generatin Matriks (NGM). Hasilnya jika , maka titik kesetimbangan e...

Four principal factors contribute to grain-boundary strengthening: (a) the grain boundaries act as barriers to plastic flow; (b) the grain boundaries act as dislocation sources; (c) elastic anisotropy causes additional stresses in grain-boundary surroundings; (d) multislip is activated in the grain-boundary regions, whereas grain interiors are initially dominated by single slip, if properly ori...
