An important concern in language acquisition research is that behavior on a given task can be indicative both of children’s underlying knowledge and of their ability to deploy that knowledge. Therefore, to accurately uncover the nature of children’s grammatical knowledge, it is necessary to take into account variability in deployment processes. In this study, we will use children’s acquisition ...

Abstract This paper compares the degradation of sintered silver (s-Ag) die attach between thermal shocked test (TST) and mechanical cycling to correctly understand mechanism s-Ag failure in power module products during practical operation. A bar-shaped specimen is subjected two types four-point bending tests: centered (CBT) for moment application shifted (SBT) shear force application. crack pat...

The problem of biomass combustion and co-combustion is a particularly important aspect many district heating systems, where the use makes it possible to reduce CO2 emissions. present article continuation previous studies behavior mineral matter selected fuels during sintering processes. Three biomasses were studied: wheat straw, barley straw rye as well two coals from Polish mines: bituminous c...

the main purpose of this study is measuring and comparing of peanut harvesting loss in manual and mechanical methods in addition to economic analysis of them. hence, a field was selected in astaneh-ashrafiyeh and divided to three different plots. two plots were applied to measure mechanical harvesting loss and third one was applied for manual harvesting loss. according to test results, the lowe...

background : since the use of high concentrations of oxygen in infants may lead to chronic lung problems, using proper methods of care in infants under mechanical ventilation is one of the most important measures in nicu. this study aimed to investigate the effects of prone and supine positions on oxygenation (spo 2 ) in premature infants under mechanical ventilation and comparing infants’ oxyg...

The present study aims to establish comprehensive test methods to evaluate the mechanical properties of the intravascular coronary stent with a closed cell design. We focused on three important mechanical properties required to the stent, bending flexibility, radial strength, and longitudinal strength. Test apparatuses and testing procedures were then developed for precise evaluation of those p...
