Sixty patients (48 male, 12 female; median age 32 (range 16-72) years) underwent pleural abrasion for persistent or recurrent pneumothorax. Fifty patients had recurrent pneumothorax and 10 persistence of a first pneumothorax despite conservative treatment; two had bilateral pneumothoraces. Pleural abrasion was carried out with a domestic nylon scouring pad and blebs or bullae were ligated or st...

Enterotoxigenic Escherichia coli is a major problem in the swine industry and results in scouring, increased mortality, and poor performance in the period immediately postweaning. The traditional way to control this problem is to include subtherapeutic antibiotics in the feed, but this is no longer acceptable to consumers; thus, alternatives to antibiotics are needed. One of the supplements tha...

Abstract Preventing plunge pool scouring in hydraulic structures is crucial engineering. Although many studies have been conducted experimentally to determine relationship between the scour depth and water jets several fields, available equations deficiencies calculating exact due complexity of process. This study investigated local using Metaheuristic Artificial Bee Colony-Optimized Feed Forwa...

Abstract The study of scouring around bridge piers is very significant and plays a important role in the safe economical design piers. term process by which bed particles periphery pier get eroded removed over certain depth resulting formation scour hole This paper presents detailed investigation local six different shapes namely rectangular, circular, chamfered, joukowsky, oblong, sharp-nosed ...

The nutritive value of isonitrogenous and isoenergetic levels of these processed beans, raw NB-SOY and NB-SOY extruded at 121, 135 or 157OC was assessed by pig growth assay. The raw NB-SOY diet caused severe scouring and was fed only for two weeks. Growth rate and feed conversion of pigs fed extruded NB-SOY improved as the extrusion temperature increased to 135OC but declined with higher temper...

Thirty-two Friesian calves less than one week old were purchased at a country market and fed a milk replacer at two rates, the feed being given as either one or two feeds only. Lucerne hay was available ad libitum from the start of the trial with restricted access to crushed oats after one month. The mean body weights of the once.-daily fed calves were higher than those of the twice-daily fed c...

Stream channel recovery from recent large floods in northern California involves a sequence of processes, including degradation of streambeds to stable levels, narrowing of channels, and accentuation of riffle-pool sequences. Most channels have degraded but remain widened because hillslope encroachment and establishment of riparian groves conducive to sediment deposition have not yet caused str...
