Crab shedding-system designs

There are as many ways to build and arrange crab shedding setups as there are people who make them. The following drawings are suggestions based on the experiencesof successful shedders. You may find changes that suit your operation better. (8pp.

Linseed Oilmeal Gives Best Cattle Finish

It may not be the fat, but some other things- nobody knows what- that put the fancy finish on cattle that are fed linseed oilmeal. That\u27s what experimenters are thinking now, after a test at the Iowa State

La homeostasis familiar y el médico

Physical illness, including psychosomatic disorders, often play an unexpected role in maintaining emotional balances within the family. The outbreak of such disorders, conversely, can be utilized by the physician as a barometer of family emotional difficulties.La maladie physique, inclus les désordres psychosomatiques, ont souvent un rôle inattendu dans le soutien émotionnel du équilibre dedans la famille. L’ arrivée de ces désordres, elle aussi, peut être utilisée par le médecin comme un baromètre des difficultés émotionnelles de la famille.La enfermedad física, incluidos los desórdenes psicosomáticos, a menudo juegan un papel inesperado para mantener el equilibrio emocional dentro de la familia. El surgimiento de esos desórdenes, igualmente, puede utilizarse por el médico como un barómetro de las dificultados emocionales familiares

Virus-Host Interactions Within Galveston Bay, Texas

Viruses are among the most abundant biological entities in the world, numbering approximately 4x1030 in the ocean alone. Despite the inherent importance of viruses, aspects of host preferences and specificity within the environment remain understudied. This study aimed to connect environmental phages to their environmental bacterial hosts. To this end, two different culture-independent methodologies allowed for the association of viruses to their hosts. First, a new method was tested that allowed for the visualization of virally infected cells through fluorescence microscopy. Secondly, co-occurrence networks were used to analyze PCR amplicons of bacteria and viruses from monthly samples. Together, these approaches allowed for coverage of a much wider range of marine bacteria and their viruses than previous studies. The methods can also lead to flow cytometry sorting and single cell genomics, allowing for a deeper understanding of the infection types present

Trial Practice and Tactics in Employee Injury Cases -- The Defendant\u27s Viewpoint

Due to the liberal construction that courts give workmen\u27s compensation statutes, the employer has heavy odds against him in most cases. Nevertheless, the author concludes, defense counsel should not despair. Hard work and proper preparation will still yield handsome rewards, especially in those cases in which the principal issue is the nature and extent of disability

Modular Autonomous Biosampler (MAB)- A prototype system for distinct biological size-class sampling and preservation

Presently, there is a community wide deficiency in our ability to collect and preserve multiple size-class biologic samples across a broad spectrum of oceanographic platforms (e.g. AUVs, ROVs, and Ocean Observing System Nodes). This is particularly surprising in comparison to the level of instrumentation that now exists for acquiring physical and geophysical data (e.g. side-scan sonar, current profiles etc.), from these same platforms. We present our effort to develop a low-cost, high sample capacity modular,autonomous biological sampling device (MAB). The unit is designed for filtering and preserving 3 distinct biological size-classes (including bacteria), and is deployable in any aquatic setting from a variety of platform modalities (AUV, ROV, or mooring)

Physical Mechanisms of Seismic-Wave Attentuation

The theoretical and experimental evidence concerning mechanisms likely to be responsible for the attenuation of seismic waves are reviewed. Intergranular thermoelastic relaxation, atomic diffusion, and dislocation mechanisms cannot be ruled out as significant causes of seismic attenuation, but the most effective mechanisms seem to be associated with partial melting, grain-boundary relaxation, and a poorly understood mechanism called ‘high-temperature, internal-friction background’ which obeys an equation of the form Q^(-1) = (A/ƒ) exp (—H*/RT). Here Q^(-1) is a dimensionless measure of anelasticity, f is the frequency, T is the absolute temperature, and A, H*, and A, H*,and RR are constants for a material of uniform composition and grain size. Many of the mechanisms considered here have a strongly frequency-dependent Q^(-1). However, in a material as complex as a rock, there is unlikely to be a single discrete relaxation time or activation energy, or a single ‘typical’ grain size. The observed Q^(-1) is likely to result from a superposition of several mechanisms and involve a spectrum of parameters leading to weaker frequency dependence than is predicted from a single simple mechanism. The seismic data cannot at present resolve the question of whether or not Q^(-1) has an intrinsic frequency dependence. The extent and the limitations of the available seismic data are discussed. Experimental data on the attenuation of oxides are summarized, the measurements at high temperature and low frequency being emphasized
