In terms of pellet mill operations, the conditioning process has greater influence on pellet quality than does die specification. A great deal of attention must be paid to steam quantity and control, moisture content, retention time and mixing action within the conditioner. In general, most feed manufacturers have not optimized the conditioning process but try to solve pellet quality issues usi...

This review gives an account of some of the factors affecting the transport of oxygen from the lungs until its final discharge in the tissues. The sequence of physiological and metabolic processes to be described may be considered collectively as the 'coarse adjust-ment' of oxygen transport. The 'fine adjustment' will be discussed in the succeeding chapter which surveys the local factors influe...

no. ISTN3X; 96% identical), comprising one of Tn3-like inverted repeats and putative coding regions for transposase, resolvase (also called repressor), and ampicillin resistance. The resistance gene encodes a TEM-1 type β-lactamase. (The sequence has been registered to DDBJ/GenBank/ EMBL with accession no. AB103092.) Conjugative transferability of p981123 between S. Enteritidis strains was exam...

~;There has been much documentation of differences in severity of disease, alteration of the disease pattern, development of overt or latent infection, and duration of the carrier state in animals of various ages. However, few attempts have been made to compare pathogenesis of disease at periods of susceptibility and refractoriness in order to gain insight into fundamental mechanisms involved. ...

Numerous factors have been reported to influence lactation. The role they play is hard to assess, and is generally based on either clinical impressions or inclusive evidence. Views on the importance of certain factors are conflicting, and from time to time a different factor is regarded as the most significant. Thus in the past different remedies have been advocated for difficulties in breast f...

Until comparatively recently it was considered to be self-evident that wound healing and infection were both parts of the same process. The words 'laudable pus' speak for themselves. De Chauliac and Pare were amongst the first generation of surgeons who were dissatisfied with this concept, and showed that healing could be achieved without infection if better treatment was applied to the wound. ...

Birth weight remains one of the most important measures we have of the health status of a population, and is a strong predictor of both neonatal mortality and morbidity. It reflects maternal nutritional status and fetal growth rates in the antenatal period. Although a large number of physiological and pathological variables can affect the growth rate, for most cases of growth-restricted fetuses...

Performance Influencing Factors, or PIFs, are factors that combine with basic human error tendencies to create error-likely situations. In general terms PIFs can be described as those factors which determine the likelihood of error or effective human performance. It should be noted that PIFs are not automatically associated with human error. PIFs such as quality of procedures, level of time str...

The demand for better services by customers and citizens keeps increasing at a rapid rate, enabling organizations the leverage towards competitive advantage. The enterprise architecture (EA) has merged as a possible solution for addressing organizational challenges, as well as for competitiveness and sustainability. The EA deployment involves agents, which are both human and non-human. The agen...

A survey is reported of infant feeding practice at the time of discharge from a single maternity ward. It is shown that a change in the attitude of nursing staff increased the number of mothers breast feeding their infants and eliminated the practice of giving the infants formula feed complements. This change in attitude, however, did nothing to prevent the rapid decline in lactation after leav...
