Effects of 2 pellet diameters for piglets pre- and postweaning on feed intake, BW, and feed-related behavior were studied in 3 experiments. In Exp. 1, 19 litters were provided with pellets of 2 and 12 mm in diameter in a choice-feeding setup from d 4 of lactation onward. From d 4 to 18, piglets preferred the 12-mm diameter pellet over the 2-mm diameter pellet (519 vs. 168 g/pen; P < 0.001). In ...

To preserve epithelial barrier function, dying cells are squeezed out of an epithelium by "apoptotic cell extrusion." Specifically, a cell destined for apoptosis signals its live neighboring epithelial cells to form and contract a ring of actin and myosin II that squeezes the dying cell out of the epithelial sheet. Although most apoptotic cells extrude apically, we find that some exit basally. ...

This paper reports on an experimental and finite element analysis (FEA) of the cold extrusion of high-grade (AA1100) aluminium. The influence of die angle, reduction ratio and die land on the extrusion force during the extrusion process was investigated. A forward extrusion die was designed and manufactured for the purpose of the experimental research. Interchangeable elements of the extrusion ...

There is limited knowledge about energy and carbon emission performance comparison between additive fused deposition modeling (FDM) consolidation plastic injection molding (PIM) forming techniques, despite their recent high industrial applications such as tools fixtures. In this study, developed empirical models focus on the production phase of polylactic acid (PLA) thermoplastic polyester life...

The simplest, most cost-efficient, and widespread Additive Manufacturing (AM) technology is Extrusion (EAM). Usually, EAM performed with filament feedstock, but using pellets instead of filaments yields many benefits, including significantly lower cost a wider choice materials. High-performance polymers offer high strength even when produced AM technique, allowing to produce near-net-shape func...

T HE volume o’ f literature considering the food habits of owls approaches prodigious proportions (see Earhart and Johnson, 1970). Much of this information has been derived from analysis of the pellets of non-digestible matter which these raptors egest periodically. A number of authors have reviewed this technique and its applications (Craighead and Craighead, 1956; Errington, 1930, 1932; Fishe...

Various investigations have focused on understanding the relationship between mucosal serotonin (5-HT) and colonic motility, however contradictory studies have questioned the importance of this intestinal transmitter. Here we described the fabrication and use of a fecal pellet electrochemical sensor that can be used to simultaneously detect the release of luminal 5-HT and colonic motility. Feca...

AN IN VITRO COMPARISON OF THE SETTING OF MTA WITH AND WITHOUT THE APPLICATION OF A MOIST COTTON PELLET Craig D. Johnson, D.D.S. Marquette University, 2010 Introduction: The purpose of this study was to compare the setting of MTA with and without the application of a moist cotton pellet. Methods: Fifty samples of MTA were mixed according to manufacturer’s instructions, placed with an amalgam car...

The efficiency of pellet injection and the relationship between D/T fuel ratio and plasma parameters were analyzed numerically using the TOTAL (toroidal transport analysis linkage) simulation code, which consists of the equilibrium calculation code and a one-dimensional transport simulation model. The simulation which included scanning the pellet penetration depth and the pellet D/T ratio was p...

in this study, the isothermal reduction of iron oxide pellets, made of iranian chadormalo, gole-gohar, and sangan iron ores, was investigated in the temperature range of 900-1100°c. tabas, pabdana, babnizoo, karmozd, and shahrood domestic coals were used as reductants. parametric studies were performed and the effects of such factors as temperature, average particle size of iron ore and coal fi...
