The following are descriptions of three types of home-made log turners and accessory deck equipment as amplifications of equipment available from manufacturers of sawmill machinery.
Sclereids are sclerenchyma cells having thick lignified
secondary walls. Douglas-fir sclereids, also called bast fibers,
are long (1 mm in length), sharply pointed, spindle-shaped fibers
of a red-brown color. Sclereids from Douglas-fir bark and nine
other western coniferous species were examined for their morphology.
The external surface characteristics of sclereids...
Ti-6Al-2Sn-4Zr-2Mo-0.1Si specimens were shaped by repeated cycles of heating
(to 954 °C) and hammer or press forging followed by a solution anneal that varied from
968 to 998 °C. The coupons were originally extracted from billets forged below the beta
trans us ( 1009 °C) and slow cooled to ambient...
Although fluoride is an important trace element in the prevention of dental caries,
it has a narrow range between beneficial and toxic effects. Excessive fluoride intake for
example can cause dental fluorosis in infants and children whose teeth are still
developing. The primary source of this unwanted fluoride has been...
Knowledge of the viruses which are mechanically transmitted
from pear to herbaceous plants and the diseases they cause in pear
is not complete. This thesis discusses the means used to mechanically
transmit pear viruses, the properties of those viruses and their
relationships with latent viruses of apple.
Herbaceous plant virus...
The potential of mechanically applied straw mulch to reduce nutrient, pesticide and sediment losses from furrow irrigated onions and increase water use efficiency was evaluated on a Nyssa silt loam with three percent slope. Nitrogen and phosphorus losses in the runoff were of particular interest, both because of their economic...
The implementation and construction of Mechanically Stabilized Earth (MSE) walls has undergone substantial expansions in recent years, owing to its relatively low cost, ease of construction, and high efficiency compared to conventional retaining methods. As a result, MSE walls are being constructed to greater heights with complex features (e.g. multiple...
