A significant fraction of white dwarfs show metal lines indicative pollution with planetary material but the accretion process remains poorly understood. The main aim this paper is to produce a road-map illustrating several potential routes for dwarf and link these paths observational outcomes. Our proposed road begins tidal disruption scattered asteroid formation highly eccentric disc wide ran...

The paper considers the issues of energy consumption and effectiveness using aluminous slag as an expansion agent compared to Portland cement. Aluminous is a difficult material grind, but its use additive in demand for building materials. following research methods were used: grinding materials, sieve analysis, electron microscopy. According results studies, it was found that effective

Both the high phosphorus (P) content and P bioavailability of the animal feed coproducts of the corn-ethanol industry could potentially contribute to increased manure and soil P levels and associated environmental issues (e.g., eutrophication). Therefore, a detailed modeling of total P mass flow to the coproducts (i.e., dry distillers grains with solubles, DDGS) was performed. Distribution of P...

We document three facts about the labor supply of Kenyan bicycle-taxi drivers: (1) drivers work more on days with higher cash needs; (2) the quitting hazard increases once the day’s need is reached; but (3) randomized cash payouts have no meaningful effect on labor supply. These results are consistent with models in which workers have reference-dependent preferences over earned income targets. ...

Vitreousness and Stenvert kernel hardness characteristics in corn germplasm have been related to in situ and in vivo starch digestibility in lactating dairy cows. Because of the tedious nature of determining vitreousness by manual dissection or conducting Stenvert hardness measurements, it is challenging to screen corn germplasm for animal performance potential. The resistance of corn to grindi...

Ground beef has been implicated as a transmission vehicle in foodborne outbreaks of infection with pathogens such as Escherichia coli O157:H7 and Salmonella. During outbreak investigations, traceback of contaminated beef to the producing facility is often unsuccessful because of inadequate recordkeeping at retail establishments that grind beef products. We conducted a survey in three states par...

meet the growing demand for transportation fuels. The main hurdles to be overcome include feedstock-supply logistics, conversion technology and workforce availability. agronomists, agricultural engineers, and implement-manufacturing companies are addressing feedstock production, harvest, storage and transportation. Several universities, especially those in the Midwest, are developing new curric...

Protein kinase B-β (PKBβ/Akt2) is a serine/threonine-specific protein kinase that has emerged as one of the most important regulators of cell growth, differentiation, and division. Upregulation of Akt2 in various human carcinomas, including ovarian, breast, and pancreatic, is a well-known tumorigenesis phenomenon. Early on, the concept of the simultaneous administration of anticancer drugs with...

Six hundred ten crossbred-yearling heifers (347 +/- 5 kg of initial BW) were obtained and used in a randomized complete-block design finishing study. Finishing diets were based on steam-flaked corn and ground alfalfa hay. The control (CONT) treatment contained no distillers grains with solubles (DGS), the second diet was formulated to contained 13% (DM basis) dried corn DGS derived from a tradi...

Dry-grind ethanol plants have the potential to reduce their operating costs and improve their net energy balances by using biomass as the source of process heat and electricity. We utilized ASPEN PLUS software to model various technology bundles of equipment, fuels and operating activities that are capable of supplying energy and satisfying emissions requirements for dry-grind ethanol plants of...
