BACKGROUND Conventional vaccination programs using a single injection of a combined vaccine against porcine circovirus type 2 (PCV2) and Mycoplasma hyopneumoniae (MHYO) can promote a strong immune response that reduces feed intake for 24 to 48 h post injection. Often such vaccines are given around the time of weaning during a critical stress period in which feed intake is already compromised. S...

The sparkling wine market has expanded in recent years, boosted by the increasing demand of the global market. As for other fermented beverages, technological yeasts and bacteria selected to design commercial starter cultures represent key levers to maximize product quality and safety. The increasing economic interest in the sector of sparkling wine has also implied a renewed interest in microb...

this study was carried out to assess the effects of alfalfa hay level and replacing corn grain by other grains in starter on daily feed intake, average daily gain (adg) and feed efficiency (fe) of pre and post-weaning dairy calves during the pre and post-weaning periods. for this purpose, a database meta-analysis used in the present study. statistical analyses were performed using proc mixed in...

The high noise sensitivity of the Wigner distribution makes smoothing a necessity for producing readable time-frequency images of noise corrupted signals. Since h e a r smoothing suppresses noise at the expense of considerable smearing of the signal components, we explore two nonlinear denoising techniques based on soft-thresholding in an orthonormal basis representation. Soft-thresholding prov...

A major credit shock can induce large intra-day variation margin payments between counterparties in derivatives markets, which may force some participants to default on their payments. These payment shortfalls become amplified as they cascade through the network of exposures. Using detailed DTCC data we model the full network of exposures, the shock-induced payments, the initial margin collecte...

The article describes the method of predicting reliability and durability an aircraft commutator, which is a primary source electric energy in helicopters. Tests were conducted for 10 starter-generators. From this research it follows that technical condition brushes bearings has significant impact on starter-generators was determined based consisting two stages adopted: first stage involved det...

Inoculation at alkaline pH (above 9) of lye-treated green olives with starter cultures of Lactobacillus pentosus CECT 5138 was studied. Despite an initial loss of viability in the order of 1-2 log cycles on average, depending mainly on time of application, cultures grew and initiated an accelerated fermentation process. Inoculation reduced the population of Enterobacteriaceae, and thereby poten...

A cover starter is a single vector that yields a covering array under the actions of groups on both the columns and the symbols of the starter. The existence of this compact representation of covering arrays facilitates effective exhaustive and heuristic search. When the group action on symbols fixes a small number f of symbols, such cover starters lead to covering arrays that embed covering ar...
