OBJECTIVE A study was conducted to test six threonine (Thr) levels (0.39%, 0.44%, 0.49%, 0.54%, 0.59%, and 0.64%) to estimate the optimal dietary Thr requirements for Longyan laying ducks from 17 to 45 wk of age. METHODS Nine hundred Longyan ducks aged 17 wk were assigned randomly to the six dietary treatments, where each treatment comprised six replicate pens with 25 ducks per pen. RESULTS...

this research chiefly focused on the application of mitigation strategies and traditional form of feedback in writing development of the fifth semester university students majoring in tefl and english translation fields based on vygotsky’s sociocultural theory in general and the notion of “zone of proximal development” in particular. to that end, this study relied on a pre-posttest experimental...

Tyrosine (Tyr) is an essential amino acid in phenylketonuria (PKU) because of the limited hydroxylation of phenylalanine (Phe) to Tyr. The recommended intakes for Tyr in PKU are at least five times the recommended phenylalanine intakes. This suggests that Phe and Tyr contribute approximately 20 and 80%, respectively, of the aromatic amino acid (AAA) requirement (REQ). In animals and normal huma...

This paper designs a reliability distribution network with limited capacity under partial and complete facility disruptions. To increase the reliability of the distribution network, a new mixed integer linear programing model is developed by considering multiple mitigation strategies including diversification, fortification, and transshipment. The distribution network constitutes of reliable di...

Contingency is necessary to mitigate and control risk associated with construction projects. Successful contingency estimation and risk mitigation strategies can help project managers to effectively control cost and schedule. Some practitioners mitigate risk by transferring it to another party with less effort and minimum cost. However, this may lead to undesirable results such as; useless depl...

Genuine Criticism (GC) is an evaluative expression of annoyance with an attribute in the interlocutor, whose realization may threaten the positive image of both interlocutors. The current study investigates facework and politeness in performing GCsin different contexts and for interlocutors with low social distance and high status in terms of GC realization strategies and mitigation devices tha...

Aging is a natural process of life. The causes of aging may come from different sources, both internally and externally. Cellular aging may lead to organ dysfunction during this complicated, irreversible process. Shortening of telomeres during each cell division may lead to cell death; a cell stops dividing while its telomeres shrink to a critical minimum size; and it is one of the causes found...

The aim of this study was to use meta-analysis to identify the enteric methane (CH4) mitigation strategy that reduced CH4 emission without lowering production. To this end, a database initially developed was updated, compiling data from 61 publications (233 experiments) for various observations in dairy cattle on effects of hydrogen sink (H-sink), ionophore, lipid and conc...
