The behaviour of alkali metals, especially of potassium, during circulating fluidised bed combustion of wood-based fuels was studied experimentally in pilot-scale and industrial scale combustors. The fuels included willow, forest residue and waste wood co-combusted with paper mill sludge. As a result of this work, the main chemical and physical transformation mechanisms of potassium compounds i...

Tracheoinnomate artery fistulas (TIF) are a rare but deadly complication of tracheostomy. This study summarizes TIF cases in the literature and seeks to understand associations with mortality. MEDLINE was searched (up May 2021) for studies reporting individual clinical demographic characteristics patients TIFs after Exclusion criteria were: no tracheostomy tube place at time fistula or addition...

The femur, a rib, and a third metacarpal were collected from 108 barrows (initial weight = 57 kg) and analyzed to determine the effects of porcine somatotropin (pST) and dietary lysine on bone mineralization and mechanical properties. In Exp. 1, pigs were injected daily with 4 mg of pST and fed diets containing 1.0% Ca and .9% P and either .6, .8, 1.0, 1.2, or 1.4% lysine. Control pigs (placebo...

The present study was performed for the development of physico-chemical parameters of Carica papaya Linn. leaves belonging to family Caricaceae. The study comprises physico-chemical and phytochemical evaluation to confirm purity and authenticity of Carica papaya leaf based on WHO guidelines. Microscopy of the leaf showed presence of epidermis, collenchyma, and parenchyma, scellerenchyma, xylem,...

In the present work, the ash transformation and deposition behavior during wheat straw and wood waste combustion were investigated by combustion experiments in an entrained flow reactor. The influence of sewage sludge addition on ash chemistry and deposition tendency was also studied. During combustion wheat straw, fine fly ash particles smaller than 2.5 μm are mainly formed due to vaporization...

Multiple Sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system. It is a clinically heterogeneous disorder especially in terms of disease severity. Current investigations suggest that genes and gene-gene interactions not only influence on susceptibility to MS but also affect the disease severity. In this study, we investigated the contribution of the HLADRB1*1501 ...
