A Factual Reply to: Is There Money in Sheep?

The number of records received from producers this year was 33% higher than the number received last year. Several records indicated that part of the flock lambed twice in 1965. These records have been summarized in Table 2. Both tables 1 and 2 provide information that you can use to evaluate your own flock\u27s performance

Minerals for dairy cattle

3/80/10MSupplying minerals for all dairy cattle is common practice. However, the kind of minerals used and the method of feeding varies from one farm to another. The purpose of this guide is to present requirements, deficiency signs, supplements and methods of feeding.Rex E. Ricketts (Department of Dairy Husbandry, College of Agriculture

Is EMDR an Evidenced-Based Treatment for Depression? A Review of the Literature

It is not unusual for proponents of eye movement desensitization and reprocessing (EMDR) to claim it can be used to treat many mental health problems. Depression is an illness that affects the lives of millions across the world; the costs are high, economically and socially, and depression can be devastating for the individual. Despite this, depression is not well treated, so a desire to find other treatments is admirable. However, these treatments must be evidence based and although there is some evidence that EMDR may be a promising new approach, it cannot currently be described as an evidenced-based treatment for depression. There are studies under way across Europe that may produce the evidence needed to expand the recommendations for using EMDR with more than just posttraumatic stress disorder (PTSD)

Outline for dairy sire selection

From University of Minnesota Extension Folder 355Dairy managers have two alternatives when they desire and need to replace the current milking herd with cows that have more potential for profit. They may buy better cows or breed better cows, the latter being more common. To produce replacements within the herd most successfully, dairy managers must produce the maximum number of heifers, reduce involuntary cow losses, and choose parents wisely. This guide covers bull selection.Clinton E. Meadows (Michigan State University), Adapted by Rex Ricketts (Dairy Husbandry Department, College of Agriculture)New 9/79/8

An overview of aeroelasticity studies for the National Aerospace Plane

The National Aero-Space Plane (NASP), or X-30, is a single-stage-to-orbit vehicle that is designed to takeoff and land on conventional runways. Research in aeroelasticity was conducted by NASA and the Wright Laboratory to support the design of a flight vehicle by the national contractor team. This research includes the development of new computational codes for predicting unsteady aerodynamic pressures. In addition, studies were conducted to determine the aerodynamic heating effects on vehicle aeroelasticity and to determine the effects of fuselage flexibility on the stability of the control systems. It also includes the testing of scale models to better understand the aeroelastic behavior of the X-30 and to obtain data for code validation and correlation. This paper presents an overview of the aeroelastic research which has been conducted to support the airframe design

Forages for cattle : new methods of determining energy content asnd evaluating heat damage

"The crude fiber method of feed analysis has been used for more than 100 years. Although this method was an important first attempt at determining the energy content of feeds, it has a number of shortcomings."--First page.Ronald L. Belyea and Rex E. Ricketts (Department of Dairy Science College of Agriculture)Revised 11/86/8

NASP aeroservothermoelasticity studies

Some illustrative results obtained from work accomplished under the aerothermoelasticity work breakdown structure (WBS) element of the National Aerospace Plane (NASP) Technology Maturation Program (TMP) are presented and discussed. The objectives of the aerothermoelasticity element were to develop analytical methods applicable to aerospace plane type configurations, to conduct analytical studies to identify potential problems, to evaluate potential solutions to problems, and to provide an experimental data base to verify codes and analytical trends. Work accomplished in the three areas of experimental data base, unsteady aerodynamics, and integrated analysis methodology are described. Some of the specific topics discussed are: (1) transonic wind tunnel aeroelastic model tests of cantilever delta wing models, of an all-moveable delta-wing model, and of aileron buzz models; (2) unsteady aerodynamic theory correlation with experiment and theory improvements; and (3) integrated analysis methodology results for thermal effects on vibration, for thermal effects on flutter, and for improving aeroelastic performance by using active controls

The epidemiology of Creutzfeldt-Jakob disease in Canada: a review of mortality data.

Creutzfeldt-Jakob disease (CJD), and particularly its transmissibility through blood and blood products, has become a focus of concern in Canada. The recent identification of new variant CJD led to a review of the Canadian mortality database to identify any clustering of CJD by age, sex, or geographic location
