- Abstract:
- ... By a simple modification, the rheovibron can be used to measure the dynamic mechanical properties of polymeric samples in equilibrium with liquids. Recent studies have shown that liquids capable of specific strong interaction with polymers can cause crystallization to occur. To demonstrate the utility of the modified rheovibron, it has been used to investigate the effect of liquid-induced crystall ...

- Abstract:
- ... Bromide has desirable characteristics for use as a tracer for NO₃⁻ in some soil studies. However, its quantitative determination in the presence of Cl⁻, which occurs in interfering quantities in many soils, requires lengthy procedures. Further, Br⁻ interferes with the quantitative determination of Cl⁻ for which concentrations may also need to be determined. To facilitate the use of Br⁻ as a tracer ...

- Abstract:
- ... Bromide has desirable characteristics as an indicator of nitrate movement in soils, although it has not been tested under field conditions. We studied its field applicability by growing sweet corn (Zea mays L.) on plots to which a mixture of sodium nitrate and sodium bromide were band applied. Irrigation was accomplished by either furrow, sprinkler or subirrigation. Nitrate and Br⁻ moved together ...

A field study was conducted to determine the influence of sprinkler irrigation (Sp), furrow irrigation (F), subirrigation (Su), and automated subirrigation (ASu) on the water requirements of sweet corn (Zea mays L.). Irrigation water was applied to the SP, F, and Su plots when the soil water potential at the 30-cm depth in the row reached −40 cbars potential. The time and amount of water applied w ...

It was determined that significant levels of longitudinal shrinkage were induced in the cold-drawn films by methylene chloride, dioxane, and nitromethane liquids at temperatures ranging from 5 to 75°C. The kinetics of shrinkage were found to be relatabte to the sorpti ...

- ... The use of tensiometers to schedule irrigations has teen limited primarily to summer crops because of water freezing in the tensiometers during the winter months. Since methanol-water mixtures have lower freezing points than water, a greenhouse study was conducted using an Olton loam soil (Acridic Paleustolls) to determine the effect of a methanol-water mixture (30% methanol by volume) on tensiome ...

We studied, directly in the field, the effects of furrow ...

A formula is derived that relates interferometer and transverse area measurements to the indices of refraction of a multiple-index fiber having an irregular transverse cross section composed of irregularly shaped regions characterized by these refractive indices. From this formula, an equation is obtained for the average index of refraction of such a fiber. Two methods are suggested for recovering ...

The shakes occurred predominantly in bands containing abnormally large amounts of axial parenchyma, traumatic parenchyma and/or vessels. These cells, of low Runkel ratio, usually separated by some form of transwall failure, exposing the cell lumen. The failure thus followed a path entailing mini ...

Collapse appeared to be restricted to fibres, although other cell types sometimes distorted in response to the stresses developed. The propensity for individual fibres to collapse was not always related to the ratio of wall thickness to lu ...

This effect of genotype outweighs that of growing conditions; indeed the influence on wood anatomy of rate of growth per se is minor. It must therefore be assumed that the reputed difference in wood quality between regrow ...

- Abstract:
- ... Bovine viral diarrhea (BVD) virus is the causative agent of fatal mucosal disease (MD) of cattle. Experimental induction of MD can be achieved by superinfection of calves persistently viremic with a noncytopathic (ncp) BVD virus using an antigenically similar cytopathic (cp) BVD virus. Here we describe the characterisation of BVD viruses isolated from three cases of experimentally induced MD. One ...

- Abstract:
- ... To study the development of lesions in mucosal disease, the spread of cytopathogenic (cp) bovine virus diarrhea virus (BVDV) to different organs was examined in relation to the time post inoculation (pi). Mucosal disease was induced in 15 persistently viremic cattle from two herds by intranasal inoculation with antigenically similar cp BVDV strain. This strain reacted with one additional monoclona ...

- Abstract:
- ... Dead wood belongs to the characteristic elements determining the structure of virgin beech forests. The present study aims at developing a concept for the cultivation and generation of dead wood in sustainably managed beech forests. As a first step a random test is carried out to quantify the dead wood of eleven beech forests aged between 133 and 193 years. The forests subject to this study appear ...

- Abstract:
- ... Mucosal disease (MD) can be induced in cattle persistently infected with noncytopathogenic bovine viral diarrhea virus (ncp BVD virus) by superinfecting them with antigenically related cytopathogenic (cp) BVD virus strains. While some of these animals succumb to early onset MD after 2 to 3 weeks post infectionem (p.i.), others only react by producing neutralizing antibodies against the cp BVD viru ...

- Abstract:

Industrial biotechnology has evolved as a significant manufacturing tool for products like fuel-grade ethanol, organic acids and bulk amino acids, but most items are still speciality products for food and pharmaceutical applications. Current development projects within the chemical industry, including lactic acid and 1,3-propanediol based polymers and plastics, indicate that new biotechnological p ...

- Abstract:
- ... Infraspecific relationships and population parameters are largely unknown in the ecologically significant mud snail genus Hydrobia s.I. We therefore studied infraspecific variation, population structure and gene flow in two Hydrobia species with different life history strategies: the marine, planktonic H. ulvae and the brackish-water, directly developing H. ventrosa. Based on sequencing data of a ...

- Abstract:
- ... The metabolism and distribution of [2,3-14C]acrolein were studied in a lactating goat orally administered 0.82 mg/kg of body weight/day for 5 days. Milk, urine, feces, and expired air were collected. The goat was killed 12 h after the last dose, and edible tissues were collected. The nature of the radioactive residues was determined in milk and tissues. All of the identified metabolites were the r ...
