Milk yield, milk flow, and udder morphology traits were measured in 72 East Friesian crossbred multiparous ewes to estimate the variation in milk flow patterns present in this research flock, and to asses the repeatability of these measurements and their relationships with other lactation traits. A special milk flow apparatus designed for dairy ewes was used on two consecutive morning milkings ...

Fe-N-C have emerged as one of the best non-PGM alternatives to Pt/C catalysts for electrochemical reduction O2 in fuel cells. In this work, we explore effect steam and CO2 treatments at high temperatures on nanometric porous structure a commercial carbon black. Using those support materials, synthesize different achieve better understanding role micro- mesopores towards catalytic site formation...

OBJECTIVE To investigate how precise Descemet stripping works in posterior lamellar keratoplasty (Descemet stripping automated endothelial keratoplasty [DSAEK]) for the treatment of corneal endothelial disorders. METHODS In a prospective, single-center, nonrandomized consecutive series, 20 Descemet membrane specimens obtained after Descemet stripping in DSAEK using a Price hook were examined ...

In this work modelling and experimental validation of an integrated process for the removal of carbon dioxide from ammonia solutions is presented (decarbonisation). In this process, carbon dioxide is stripped out from the solution simultaneously with small amounts of ammonia at ambient pressure in a packed column. Recovery of the stripped ammonia can be reached by combining absorption of ammoni...

The goal of this experiment is to evaluate the effectiveness of different leachate pre-treatment options in terms of COD and ammonia removal. This research focused on the evaluation of physical-chemical methods for pre-treatment of leachate that would be effective and rapid in order to satisfy the requirements of the sewer discharge by-laws. The four pre-treatment options evaluated were: air st...

BACKGROUND One of the most frequent reasons for failure of haemodialysis lines is catheter blockage caused by fibrin sheath formation. We report our experience of percutaneous fibrin sheath stripping in treating this problem. METHODS A consecutive series of failing haemodialysis catheters underwent percutaneous fibrin sheath stripping in an attempt to retrieve and prolong the life of the cath...

The preparation of highly pure vanadyl sulfate from sulfate solutions containing impurities of iron and aluminumwas investigated by solvent extraction with 2-ethylhexyl phosphoric acid mono-2-ethylhexyl ester (EHEHPA) and tri-n-butyl phosphate (TBP) as the phase modifier. The extraction and stripping conditions of vanadium (IV) and its separation from iron and aluminum were optimized. Under the...

This paper presents an unsupervised approach for the development of a stemmer (For the case of Urdu & Marathi language). Especially, during last few years, a wide range of information in Indian regional languages has been made available on web in the form of e-data. But the access to these data repositories is very low because the efficient search engines/retrieval systems supporting these lang...
