Sizing solar systems for agriculture (1982)

"1975."Current research data indicate that active solar systems are not economical for livestock facilities if initial cost and heat production are the major considerations, But other economic factors, such as investment credit and tax incentives, may make systems feasible for some operations

Chimneys for wood stoves (1993)

All wood-burning stoves need a tight, well-designed and well-constructed chimney to maximize efficiency and minimize the danger of unwanted fire. Most homeowners who add a wood-burning stove will also have to add a chimney. This publication explains chimney requirements and provides basic information on how to construct the two general types of chimney, masonry and prefabricated metal.Reviewed October 1993

Wind energy in Missouri (1981)

Because of the rapidly increasing cost of conventional fuels many farmers are interested in the possibility of using other energy sources on the farm. This guide discusses one energy alternative, wind energy and its potential for Missouri

Partial genetic suppression of a loss-of-function mutant of the neuronal ceroid lipofuscinosis-associated protease TPP1 in Dictyostelium discoideum

Neuronal ceroid lipofuscinosis (NCL) is the most common childhood-onset neurodegenerative disease. NCL is inevitably fatal, and there is currently no treatment available. Children with NCL show a progressive decline in movement, vision and mental abilities, and an accumulation of autofluorescent deposits in neurons and other cell types. Late-infantile NCL is caused by mutations in the lysosomal protease tripeptidyl peptidase 1 (TPP1). TPP1 cleaves tripeptides from the N-terminus of proteins in vitro, but little is known about the physiological function of TPP1. TPP1 shows wide conservation in vertebrates but it is not found in Drosophila, Caenorhabditis elegans or Saccharomyces cerevisiae. Here, we characterize ddTpp1, a TPP1 ortholog present in the social amoeba Dictyostelium discoideum. Lysates from cells lacking ddTpp1 show a reduced but not abolished ability to cleave a TPP1 substrate, suggesting that other Dictyostelium enzymes can perform this cleavage. ddTpp1 and human TPP1 localize to the lysosome in Dictyostelium, indicating conserved function and trafficking. Cells that lack ddTpp1 show precocious multicellular development and a reduced ability to form spores during development. When cultured in autophagy-stimulating conditions, cells lacking ddTpp1 rapidly decrease in size and are less viable than wild-type cells, suggesting that one function of ddTpp1 could be to limit autophagy. Cells that lack ddTpp1 exhibit strongly impaired development in the presence of the lysosome-perturbing drug chloroquine, and this phenotype can be suppressed through a secondary mutation in the gene that we name suppressor of tpp1− A (stpA), which encodes a protein with some similarity to mammalian oxysterol-binding proteins (OSBPs). Taken together, these results suggest that targeting specific proteins could be a viable way to suppress the effects of loss of TPP1 function

Dynamic Response of Turbine-blade Temperature to Exhaust-gas Temperature for Gas-turbine Engines

The frequency of blade temperature to exhaust gas temperature is presented for two locations in the blade and at several operating conditions. The frequency response was determined by Fourier analysis of transient data. Two analytical methods are presented, and results are compared with experimental data. Dynamic response of turbine-blade temperature to exhaust-gas temperature exhibited the form of an approximate first-order lag. The results are used to predict blade temperature for a typical controlled and uncontrolled gas-turbine engine

Insulation for your home

"Insulation is an essential part of the heating and cooling system of a home. It adds to the comfort level in the home and reduces fuel costs. A well insulated home will have lower fuel bills for heating and air conditioning than a similar home without insulation. Bills may be as much as 50 percent lower."--First page.Richard E.

Sizing air conditioning equipment

"This Guide is intended for persons who are deciding what size air conditioning equipment to buy. The procedure is primarily for residential use, but is appropriate for other structures provided any unusual loads are taken into account."--First page.Richard E.

Energy for Missouri farm buildings

"Although energy used in agriculture is a small portion of the total energy used in the United States, it is rapidly becoming a major cost for farmers. For example, Missouri hog farmers now spend nearly $1 for heat energy per pig weaned."--First page.Richard E. Phillips (Department of Agricultural Engineering, College of Agriculture)New 3/80/15
