The objective of this study was to evaluate the effect of subcutaneous supplementation of 300 mg of zinc, 50 mg of manganese, 25 mg of selenium, and 75 mg of copper (Multimin North America, Inc., Fort Collins, Co) at 230 days of gestation, 260 days of gestation, and 35 days postpartum, on health, milk production and reproduction of lactating Holstein cows. A randomized field trial was conducted...

Requirements traceability is essential for developing software systems of high quality. Whereas the traceability of the refinement, deployment, and use of a requirement is called posttraceability, the traceability of a requirement back to its origin is named pre-traceability. In this contribution we present a requirements engineering environment, called PRO-ART*, which enables requirements pre-...

nakhlak lead mine is located at the nakhlak mountain 55 km ne of anarak town in isfahan province. the mineralogy is simple; galena and barite are the main primary minerals and cerussite is the main secondary mineral. sphalerite, pyrite, chalcopyrite, tetrahedrite-tennantite and acanthite occur as minor and trace mineral inclusions in galena. secondary minerals are anglesite, plattnerite, wulfen...

[Context & motivation] Obtaining traceability among requirements and between requirements and other artifacts is an extremely important activity in practice, an interesting area for theoretical study, and a major hurdle in common industrial experience. Substantial effort is spent on establishing such links, and keeping them up to date, in any large project – even more so when requirements refer...

Bartha, R. (University of Washington, Seattle), and E. J. Ordal. Nickel-dependent chemolithotrophic growth of two Hydrogenomonas strains. J. Bacteriol. 89:1015-1019. 1965.-The trace element requirements for growth of facultative chemolithotrophic Hydrogenomonas strains H1 and H16 were investigated under both autotrophic and heterotrophic conditions. The organisms were grown in a mineral medium,...

Solanum nigrum cultivated on different soil texture types, sandy clay loam, silty clay loam, clay loam, loam, and control soils, were evaluated for proximate compositions, antinutrients, vitamins, and mineral composition with plant age using standard analytical methods. Accumulation of trace elements using translocation factor was studied to determine their toxic levels in plant tissues. Data w...

Published data on the effects of ruminal bolus on the number of ovulatory follicles in ewes does not exist. The present study determined the effects of a ruminal bolus on trace element status, follicular dynamics and reproductive performance in ewes. Eighty Afshari cycling ewes were synchronized during breeding season using CIDR for 14 days and assigned to 4 groups (n=20); group 1 received a si...
