special features of the emulsion graft polymerization of styrene to cellulose fibres

an investigation was made the process of styrene sorption by natural (cotton) and by hydrocellulose (viscose) fibers at various stages of the graft polymerization. as the objects of investigation the authors used specimens of viscose fiber (0. 166 text), native cotton, cotton freed of oils and wax, and also specimens of the indicated fibe..

colloquium on micro-computer aided design, 1981

the digest contains 8 papers dealing generally with the use of microcomputers for computer aided design as well as specific applications such as circuit, electromagnet, and p/c layout design

method of applying a lint reducing, nonadherent facing for medical-surgical absorbent pads

data are presented which show that thermally laminating a light-weight porous, nonwoven fabric to absorbent padding leads to a significant reduction in linting tendency, while retaining good absorbency and providing nonadherence to the healing tissue. the porous nonwoven facings which have been applied by this process are of two types, di..

degradation of cotton by ionizing radiation

in the reported experiments, the effect of **6**0co $gamma$ -radiation on physical and chemical properties of raw cotton has been studied over a wide dose range from 0 up to 120 mrad. a variety of techniques - namely viscometry, infrared spectroscopy, solubility, analysis of stress-strain measurements, and scanning electron microscopy (se..

analysis of computer-simulated thermal performance: the norris cotton federal office building

five computer-based simulations of the norris cotton federal office building in manchester, nh, were performed using a state-of-the-art proprietary hour-by-hour building simulation program. results of the simulations are compared with each other and with actual measured data at several levels of detail including total energy consumption, ..

productivity of energy: engineering and economic factors

a simple and practical graphical method for making international or interregional comparisons of energy productivity has been productivity and applied to some specific significant cases the method is based on definitions of national energy productivity as gross domestic product (gdp) per unit of energy consumed, annual per capita energy c..

theoretical investigation of inlet characteristics for personal aerosol samplers

to keep the working environment free from health hazards the permissible exposure to cotton-dust has to be decreased. lower permissible exposure makes the $left double quote$ representativeness $right double quote$ of the sample more important and development of methods to estimate the sampling errors become necessary. a theoretical model..

approximating a closed-form solution for cotton fruiting dynamics

for agronomic crop-pest models, transient behavior is of primary concern, and generally for these models closed-form solutions are not possible. hence it has been necessary to utilize numerical schemes to obtain solutions to these transient problems. a nonlinear partial differential equation of the von foerster type is used to describe th..

on magnetic distortion in audio amplifiers

in audio amplifiers, distortion can be generated by a signal-current circuit (the copper foil of a p/c board and the wiring of the circuit components), because of the influence of nearby magnetic materials (the chassis, casing, power source transformer, etc. ). this paper shows the phenomenon of generation of distortion in amplifiers caus..

user acceptance of an energy efficient office building $em dash$ a study of the norris cotton federal office building

the general services administration built the norris cotton federal office building in manchester, new hampshire, and chose it as a $left double quote$ demonstration project for studying the effectiveness of energy conservation techniques in the design and operation of a contemporary office building. $right double quote$ user acceptance o..
