The present study was performed in order to evaluate the effects of lower than usual industry levels of dietary trace minerals on plasma levels, faecal excretion, performance, mortality and morbidity in growing-finishing pigs in a hot African climate. Group 1 (n = 100 pigs) received a diet with common industry levels of trace minerals. Group 2 (n = 100 pigs) received reduced dietary trace miner...

System and software requirements are inextricably intertwined, yet the challenge of extracting software requirements from system requirements is often an exercise in frustration. We propose an extension of the four-variable model originally developed by Parnas and Madey that clarifies how system requirements can be allocated between hardware and software. This extension organizes the software s...

Traceability is an important quality of software requirements and allows to describe and follow their life throughout a development project. The importance of traceable requirements is reflected by the fact that requirements standards, safety regulations, and maturity models explicitly demand for it. In practice, traceability is created and maintained by humans, which make mistakes. In result, ...

Introduction: Synchrotron x-ray fluorescence (SXRF) studies carried out on a microprobe endstation allow non-destructive analysis of both major and trace element abundances in particles only microns in size. The technique has been applied to IDPs captured in the stratosphere to study atmospheric entry effects such as stratospheric contamination and frictional heating [1, 2]. SXRF will also be a...

Pre-requirements specification tracing concerns the identification and maintenance of relationships between requirements and the knowledge and information used by analysts to inform the requirements’ formulation. However, such tracing is often not performed as it is a time-consuming process. This paper presents a tool for retrospectively identifying pre-requirements traces by working backwards ...

This study was aimed at investigating the hematological, biochemical and trace mineral status of cattle with foreign body rumen impaction. Hematological, serum biochemical and trace mineral parameters of cattle with Foreign Body Rumen impaction (FBR) and normal cattle Without Foreign Body Rumen impaction (WFBR) were analyzed in order to evaluate their influence as risk factors in the etio-patho...

Three experiments were conducted to determine the effects of omitting vitamin and trace mineral premixes and(or) reducing inorganic phosphorus additions to finishing diets on growth performance, carcass characteristics, and muscle quality in pigs. In Exp. 1, a corn-soybean meal-based diet (.70% lysine, .65% Ca, and .55% P) was used as the control. Pigs (n = 128; average initial BW of 85.7 kg) w...
