To evaluate the NH(3), N(2)O, and CH(4) emissions from composting of livestock waste without forced aeration in turned piles, and to investigate the possible relationship between the scale of the compost pile and gas emission rates, we conducted swine manure composting experiments in parallel on small- and large-scale compost piles. Continuous measurements of gas emissions during composting wer...

Chip firing is a one-player game where piles start with an initial number of chips and any pile with at least two chips can send one chip to the piles on either side of it. When all of the piles have no more than a single chip, the game ends. In this paper we review fundamental theorems related to this game on a two dimensional number line, including the fact that termination and final configur...

Patients affected by high-grade haemorrhoid with a fibrous internal pile or an important external component are suitable for an excisional procedure. The aim of this study is to evaluate the outcome of different excisional treatments such as Milligan and Morgan haemorrhoidectomy, Ferguson haemorrhoidectomy and Pexy-excision carried out according to a tailored treatment on each pathological pile...

Pile heat exchangers – where heat transfer pipes are cast into the building piled foundations – offer an opportunity to use ground energy systems without the additional construction costs related to the provision of special purpose heat exchangers. However, analysis methods for pile heat exchangers are still under development. In particular there is an absence of available methods and guidance ...

bearing capacity prediction of axially loaded piles is one of the most important problems in geotechnical engineering practices, with a wide variety range of methods which have been introduced to forecast it accurately. machine learning methods have been reported by many contemporary researches with some degree of success in modeling geotechnical phenomena. in this study, a fairly new machine l...

Municipal solid waste contains high amounts of cellulose, which is an ideal organic waste for the growth of most of microorganism as well as composting by potential microbes. In the present study, Congo red test was performed for screening of microorganism, and, after selecting a potential strains, it was further used for biodegradation of organic municipal solid waste. Forty nine out of the 25...

The purpose of this paper is to solve a special class of combinational games consisting of two-pile counter pickup games for which the maximum number of counters that can be removed on each successive move changes during the play of the games. Two players alternate moving. Each player in his turn first chooses one of the piles, and his choice of piles can change from move to move. He then remov...

OBJECTIVE This exploratory study assessed how 8-13-year-old children categorised and labelled fruit and vegetables (FaV), and how these were influenced by child characteristics, to specify second-level categories in a hierarchical food search system for a computerised 24 h dietary recall (hdr). DESIGN Two sets of food cards, sixty-seven for fruit (F) and sixty-four for vegetables (V), with pi...

When applying axial load on piles subjected to negative skin friction (NSF), the yielded NSF is gradually eliminated. The process is notably influenced by the tip location (Y) and still a lack of understanding. This paper reports three-dimensional numerical simulations with tip locations Y = 1.00 pile diameter (D), 0.25D, 0.00D, and -1.00D. It is found that, against expectations, the dragload a...

The N-heap Wythoff’s game is a two-player impartial game with N piles of tokens of sizes A1, . . . , AN , A1 ≤ ·· · ≤ AN . Players take turns removing any number of tokens from a single pile, or removing (a1, . . . , aN) from all piles — ai tokens from the i-th pile, providing that 0 ≤ ai ≤ Ai, ∑i=1 ai > 0 and a1 ⊕ ·· · ⊕ aN = 0, where ⊕ is the nim addition. The first player that cannot make a ...
