Electrical resistance of cotton-metal fibre yarns

Yarns representing cotton-metal fibre blends were studied. The electrical resistance of yarns including different fractions of cotton and metal fibres was compared with cotton yarns having the same nominal characteristics. The expected dominant role of metal fibres in conducting electric current and the decrease in yarn's electrical resis..

Hollow fiber enzymic reactors for a two substrate process: Analytical modeling and numerical simulations

The use of immobilized enzyme reactors in biotechnology and biomedicine is rapidly expanding. This study concentrates on hollow-fiber (HF) enzymic reactors for continuous, signle-pass operation. The enzyme, in a soluble form, is physically confined within the shell section of the reactor and the substrate solution flows through the lumen ..

Below-ground processes in the ARS cotton model

The second generation cotton model (SGCM) was designed as an expandable modular crop simulator. The paper presents an outline of the essential features of the below-ground component based on the two-dimensional soil and root process simulator 2DSOIL. New modules developed specifically for SGCM, and modules under development are described.

Above-ground processes in the ARS cotton moel

The new ARS cotton model has been developed by combining the best features of three earlier ARS cotton models with recent experimental results and new modeling tools. Model modularity and genericness were facilitated by using an object-oriented design programmed in C++. Every organ on the plant is represented separately. Most processes ar..

Image processing for stripper harvested cotton trash content measurement a progress report

This study was initiated to provde the basis for obtaining on-line information as to the levels of the various types of gin trash. The objective is to provide the ginner with knowledge of the quantity of the various trash components in the raw uncleaned seed cotton. This information is currently not available to the ginner for use in opti..

Uses of simulation models in precision cotton farming

Successful uses of precision farming technology depend on out ability to readily assess field variability and to relate the information to optimum management action. Current techniques used to asses field variability (soil sampling, plant mapping, and scouting) are tedious, slow and expensive. Simulation models can play an important role ..

Validation of the cotton model in the Texas High Plains

Process based crop simulation models are useful analytical tools for evaluating the relationship between particular production inputs and crop responses. The Agricultural Research Service is developing a cotton model using the objective-oriented programming language C++ and special emphasis is being placed on maintaining independence betw..

The cotton model and graphical user interface

The second generation cotton model needed a tool to simplify operation of the crop simulator by end users. Our objectives were (a) to develop a graphical user interface (GUI) specifically oriented to on-farm use, and (b) to research the possibility of building a generic GUI that could be used with many crop simulators not necessarily havi..

There are ten papers included in this publication, they are: ~ Testing electrical power systems for safety and reliability by J.B. Franklink, D. Parker and L. Cosby; A simplified approach to reliable high quality critical grade power by ..

Operational and costs characteristics of the Mississippi cotton gining industry

A survey of Mississippi coton gins was conducted to ascertain the current state of the ginning industry. Questions about capacity, transportation costs, ginning costs, and trash handling were administered. The primary results showed that the ginning industry in Mississippi has excess capacity, with the largest gins exhibiting the most exc..
