For the survival, development and gaining more profits, the enterprise must actively adopt new technology, new technique, new equipment, to produce more products with high added value, adopt necessary measures to promote the optimization of product structure and equipment structure for economic, reasonable, production.
PRODUCTION OF ANTIBACTERIAL AND ANTIFUNGAL METABOLITES BY STREPTOMYCES VIOLACEUSNIGER AND MEDIA OPTIMIZATION STUDIES FOR THE MAX
Production medium was optimized for antibiotic production.
The uniqueness of the geodesic by its initial values severely restricts the choice of the fiber path and is an obstacle to the production of optimized structures.
Under a kind of utility function and production function, we prove that these conditions are satisfied and the economy at least has an optimal growth path.
This paper formulates a kind of dynamical macro-economic model based on Sidrauski's work, then presents the sufficient and necessary conditions of the stability of model at equilibrium states, and shows some results for special production functions.
By producing a L2 convergent Neumann series, we prove the invertibility of the elastostatics and hydrostatics boundary layer potentials on arbitrary Lipschitz domains with small Lipschitz character and 3D polyhedra with large dihedral angles.
This fact causes considerable difficulties in producing lower dimensional examples of tiles which have no spectra.
An antibiotic producing strain Streptomyces violaceusniger was isolated from soil sample, characterized and studied for antibacterial and antifungal activity profile.
The activity profiles of the intracellular and extracellular crude extracts showed that the antibiotic producing culture produces two or more compounds, one being intracellular (antifungal), other being extracellular (antibacterial).
The image is realized by modulating the voltage of under-gate, whose value is less than the cathode voltage, to stop the cathode producing field emission electrons.
As an application we produce complete hyperbolic 5-manifolds that are nontrivial plane bundles over closed hyperbolic 3-manifolds and conformally flat 4-manifolds that are nontrivial circle bundles over closed hyperbolic 3-manifolds.
These results apply to produce Haar wavelet bases and certain canonical number systems.
Commonly used techniques such as circular convolution and symmetric extension can produce undesirable edge effects which propagate into the interior of the transformed data as the number of DWT iterations increases.
The "multiresolution analysis" wavelets (briefly, the MRA wavelets) have a simple characterization and so do the scaling functions that produce these wavelets.
The compounds reported here can be used to produce derivatives of other biological agents.
New Synthetic Method for Industrial Manufacture of Glutaric Dialdehyde
A new synthetic method for the manufacture of glutaric dialdehyde is investigated.
The solid-state chemical method has the advantages of low cost, low pollution, and high yield, therefore it appears to be a promising method in the industrial manufacture of nanometer MgO.
Adhesive application method in MDI-UF particleboard manufacture
In this study, we investigated the use of an emulsifiable diphenylmethane-4, 4'-diisocyanate (MDI) - urea formaldehyde (UF) mixture adhesive in particleboard manufacture, in order to decrease F-emission to below 9 mg per 100 g board.
