variace / covariance components of 227118 first lactaiom test-day milk yield records belonged to 31258 iranian holstein cows were estimated using nine random regression models. afterwards, different measures of persistency based on estimation breeding value were evaluated. three functions were used to adjust fixed lactation curve: ali and schaeffer (as), quadratic (le3) and cubic (le4) order of...

BACKGROUND The role of minerals on parasite persistency and the interaction between minerals and animal responses to the parasite infestation is not clear. For these reasons, the present research was aimed to compare copper, zinc and iron status in sheep with parasitic myocarditis and healthy ones in 2009. METHODS Blood and heart tissue samples were collected from 145 slaughtered sheep and hi...

Open distributed computing in an internetwork environment has gained considerable attention in the past few years. This paper presents COMET, a Common Object Management EnvironmenT, that investigates basic problems associated with distributed computing in an internet environment with mobile objects. COMET’s persistency support is based on typed memory, manipulated by persistent actions. The use...

What is the role of a shared whiteboard in building a shared understanding of the task and its solution? Our hypothesis was that a graphical communication tool would facilitate grounding processes, i.e. the mutual understanding of one or a few utterances and thereby the construction of a shared solution. We conducted an empirical study with 20 pairs solving an enigma in a MUD environment enrich...

Mesenchymal stromal/stem cells (MSCs) are a fibroblast-like cell population with high regenerative potential that can be isolated from many different tissues. Several data suggest MSCs as therapeutic tool capable of migrating to site injury and guide tissue regeneration mainly through their secretome. Pulmonary first-pass effect occurs during intravenous administration MSCs, where 50 80% the te...

A 1-yr calving interval (CInt) is usually associated with maximized milk output, due to the calving-related peak in yield. Extending CInt could benefit cow health and production efficiency fewer transition periods per unit of time. can affect lactation performance by days dry year, delayed pregnancy effect on yield, greater solid yield late lactation. This study first investigated effects 3 dif...
