Potentially large savings can be realized within the forest industry by improved machine scheduling, labour scheduling, machine investment, inventory management, and the maximization of wood value. Forecasting must change within the forest industry from Ttguesstimatesll to more efficient production forecasting models. Much work needs to be done with data collection...
The use of partial cutting in the western conifers has become popular in the last decade. This has resulted in an increase in the amount of damage to the residual stand due to skyline logging. The purpose of this study is to provide models to predict the percent of a...
This paper describes a mathematical formulation and computer
programs for use on hand-held programmable calculators to analyze
the load carrying capacity of skyline systems, including the effects
of log drag. The actual physical characteristics of the load and
the ground geometry are used in the analysis of the payload capacities...
This paper describes a computer program developed for the Hewlett
Packard 9830, which analyzes and computes costs and engineering
data for paper plan timber harvest road networks. The program will
accept up to 110 road segments. Each segment is analyzed individually
based on digitized data from a contour map and...
The transition of mature pollen to the progamic phase represents an important step in the regulation of plant sexual reproduction. The progamic phase encompasses the initiation of pollen tube germination, growth of the pollen tube through the stigma (the silk in maize) and concludes with fertilization of the female gametophyte....
An inventor seeks to leverage his unique means in order to create and commercially exploit new technologies. Until new technologies are sufficiently developed, they have the theoretical potential for commercial exploitation in a wide range of markets. Those opportunities are limited by physical bounds that are often only discovered through...
Techniques were developed for extracting histones from isolated
chromatin of encysted embryos of Artemia salina. Histone extracts
from embryos collected at eight time intervals after rehydration and
initiation of development were analyzed by electrophoresis for qualitative
and quantitative changes in composition. Histone to DNA ratios
were determined for the same...
Glutamine synthetase in the embryonic chick neural retina
shows a 50 fold increase in activity between the 16th and 17th day of
embryonic development. This increase in enzyme activity results
from de novo enzyme synthesis thus making it a useful marker of
differential gene expression. A precocious rise in activity...
The purpose of this thesis is to represent and calculate unsymmetrical
secondary faults on a grounded wye-to-delta transformer
bank.
This thesis is specifically concerned with the secondary connections
often encountered in industrial installations. Faults on these
systems have not been adequately investigated.
Three types of faults are considered, namely:
1....
Developmental changes in the enzymes acetylcholinesterase
(EC 3.1.1.7) and pseudocholinesterase (EC 3.1.1.8) were
examined in ovo and in vitro in the neural retina of the
developing chick. In addition, investigations of cellular
interactions and hormones as possible control mechanisms of
enzyme synthesis were made.
The specific activity of acetylcholinesterase, a...
