and has been the subject of published articles in many languages.
This peculiar injury seems to be on the increase in the United States

No-till pasture renovation can increase the quality and forage yield of underproductive pastures. Decreased erosion, lower costs, and less lost grazing time are advantages of no-till renovation compared to conventional renovation. Unwanted vegetation is first controlled with herbicides to decrease competition for introduced orchardgrass. Two field trials were conducted using...

A single cell in a 12 cell bulkhead was instrumented to observe
its behavior and confirm design assumptions during construction.
Vibrating wire strain gages were employed to measure horizontal

Independent systems theory has been used to interpret the
circular dichroism (CD) spectra in the vacuum uv of three cyclic
dimers of amino acids. First, the theory for rotational strengths is

All terms to first order in perturbation theory are kept....
Friction factors were measured for water flowing in ducts made
up of two rods held between two flat plates. Three rod diameters of
0.50, 1.00 and 1.50 inches were used. The spacings between rods
varied from 0.0 to 0.32 inch. It was found that the concept of
hydraulic diameter was...
Circular dichroism (CD) spectra were obtained for bacteriophage T4 lysozyme and three of its mutants in the presence and absence of colloidal silica nanoparticles. Mutant lysozymes were produced by substitution of the isoleucine at position 3 with tryptophan, cysteine and leucine. Each substitution resulted in an altered structural stability, quantified...

Although moss will invade well maintained lawns, it usually occurs extensively in neglected lawns where cultural conditions enable it to outcompete turf.
Many parents want their children to have positive feelings about themselves and to believe they can succeed. Children often evaluate their selfworth and make judgments about their abilities based on experiences they have at home. Families can provide numerous
opportunities every day to develop children’s self-confidence.
This publication is one of a set written to help consumers select and care for today's clothing. Three of the publications -- fibers and fabrics; information found on garment labels; and dyeing and colorfastness -- aid consumers in evaluating clothing and household textiles.
Raccoons are very interesting animals to watch because many of
their motions remind us of things we do. Raccoons walk flat footed like humans, and their front paws work a lot like human hands. Their ability to open doors, refrigerators, and garbage cans causes many conflicts between humans and raccoons.
Why be concerned about pollination? While most varieties of pear will set some fruit without cross pollination, usually they will set more and better fruit with it. Cross pollination means the transfer of pollen from the anthers of flowers of one variety to the stigma of flowers of another.

This publication describes results of field research on the performance of hard red winter wheat cultivars in a late-planted no-till fallow system in the low-precipitation zone of Oregon and Washington.
Two types of linear random wave simulation methods are investigated;
viz., (1) Deterministic Spectral Amplitude (DSA) and (2) Nondeterministic
Spectral Amplitude (NSA). These linear simulations are extended to
second-order in a perturbation expansion in the frequency domain by
utilizing a Fast Fourier Transform (FFT).
The nonlinear interaction matrix for waves...
Equipment for strip-till planting is under development in wheat-fallow
rotations in the Columbia Basin of Oregon. This involves the
absence of tillage during the fallow season. At planting time, the

The objective of this project was to evaluate methods to remediate a wood I-joist with a single, circular hole in the web while leaving utilities in place. The methods were experimentally evaluated with a full-scale bending test using four equally spaced point loads. There were three depths of joists with...
Remediation methods and strength predictions were evaluated for wood I-joists with single, circular holes in the webs, leaving utilities in place. A full-scale bending test using four equally-spaced point loads was applied to three depths of joists with varying flange widths and span lengths of 4.88 m and 2.44 m....

An experimental study was conducted to determine the hydrodynamic
forces on smooth and roughened circular cylinders as
influenced by a nearby plane boundary. The ambient flow was perpendicular
to the cylinder and parallel to the boundary. Measurements
were taken in a water channel and a wind tunnel to obtain the...
The asymptotic boundary layer problem involving an axial
incompressible Newtonian fluid flow past a circular cylinder parallel
to its axis was investigated by Stewartson (1955). He addressed hiself
primarily to the Mangler's (1948) derivation, namely, the
character of the boundary layer on a circular cylinder is equivalent to
that on...
This study was undertaken to provide information needed in the design of ocean outfalls. A review of past investigations concerning forces on submerged objects is presented. Objects independent of any boundary and cylinders in boundary contact are considered. A solution for pressure distribution about a circular cylinder resting on a...
An investigation was made to test the method of Head on the
flow about a circular cylinder with suction. The method of Head is an
