Tb73: Estimating Heat Consumption In Kiln Drying Lumber, James E. Shottafer, Craig E. Shuler
Tb73: Estimating Heat Consumption In Kiln Drying Lumber, James E. Shottafer, Craig E. Shuler
Technical Bulletins
This report presents one method for systematically estimating heat consumption in a dry kiln. The basis for evaluating heat use is presented along with a description of the specific elements of heat consumption. All necessary physical relationships are described in detail for those who wish to employ them. One point of interest here is the fact that the system described will readily lend itself to the construction of a mathematical model.
Tb72: Selection For Type And Milk Production In Dairy Cattle, Howard C. Dickey
Tb72: Selection For Type And Milk Production In Dairy Cattle, Howard C. Dickey
Technical Bulletins
This publication discusses milk production in dairy cattle, then explains type improvement, then describes one can select for both type and production with the aid of a chart.
Tb70: Physical And Chemical Changes Associated With The Development Of The Lowbush Blueberry Fruit Vaccinium Angustifolium Ait., Amr A. Ismail, Walter J. Kender
Tb70: Physical And Chemical Changes Associated With The Development Of The Lowbush Blueberry Fruit Vaccinium Angustifolium Ait., Amr A. Ismail, Walter J. Kender
Technical Bulletins
The objective of this investigation was to determine the growth characteristics, changes in the soluble solids, pH, and titratable acidity for the purpose of defining and describing stages in the growth of the blueberry fruit.
Tb71: Fiber Analysis And Distribution In The Leaves, Juvenile Stems And Roots Of Ten Maine Trees And Shrubs, Fay Hyland
Tb71: Fiber Analysis And Distribution In The Leaves, Juvenile Stems And Roots Of Ten Maine Trees And Shrubs, Fay Hyland
Technical Bulletins
The value of woody plants in the paper-making industry is unquestioned. As our present supply of the readily accessible and more valuable species of this natural resource dwindles, it may become necessary to use shrubs and waste from logging operations. This study focuses on the juvenile wood eastern white pine, red spruce, balsam fir, eastern hemlock, gray birch, red maple, quaking aspen, pin cherry, speckled alder, and slender willow.
Tb78: Sequential Surveys Of The Pine Leaf Chermid, Pineus Pinifoliae, John B. Dimond
Tb78: Sequential Surveys Of The Pine Leaf Chermid, Pineus Pinifoliae, John B. Dimond
Technical Bulletins
Sequential survey procedures are described for classifying damage to white pine produced by the pine leaf chermid. Damage classes are based on degree of needle stunting, and field procedures for making measurements are given. Survey procedures are also presented for classifying infestation levels of two stages of the insect. These allow prediction of damage levels before damage occurs.
Tb67: Pilot Study Of The Use Of Pulpwood Chipping Residue For Producing Particleboard In Maine, Craig E. Shuler
Tb67: Pilot Study Of The Use Of Pulpwood Chipping Residue For Producing Particleboard In Maine, Craig E. Shuler
Technical Bulletins
The study was conducted at the School of Forest Resources, University of Maine at Orono, as part of an extended project on the use of northeastern species for particleboard. This particular investigation served as a means to establish a laboratory board-production system, and to gather useful information regarding a specific wood resource of the state of Maine.
