Vitrification is considered to be an attractive technology for bottom ash treatment because it destroys the hazardous organics, contributes to immobilization of the heavy metals, and additionally it reduces drastically the volume. The main components of the vitrified bottom ash slag are SiO2 , CaO, Al2 O3 , Fe2 O3 , Na 2 O and MgO, and the compositions have direct effect on the glass formation ...
Bronchiolitis obliterans syndrome (BOS) remains the leading cause of morbidity/mortality following lung transplantation. In recipients with BOS, markers predicting the decline in lung function are needed. The aim of this longitudinal study was to determine whether exhaled nitric oxide fraction (FeNO) measurements provide useful information for discriminating patients with unstable BOS from thos...
WINNING ABSTRACT: BOS is the most important cause of late mortality after LTx. Until 5 years ago, the prevalence was around 30% and 50%, 3 and 5 years after LTx. Introduction of azithromycin (AZI) improved the FEV1 in 40% of BOS patients. AZI treatment may explain why in our center, the BOS prevalence at 3 years has decreased from 30% to 15% compared to the ISHLT registry. Opposed to the curren...
Argon oxygen decarburisation (AOD) slag may be used for phosphorus (P) removal, as its high pH and weatherable calcium (Ca) minerals provide sufficient Ca(2+) and OH(-) for calcium phosphate (Ca-PO4) precipitation. This study examined the P removal performance of AOD slag for use as wastewater treatment material. Batch experiments were carried out using both synthetic P solution and real wastew...
Penetration and dissolution mechanisms are reviewed for predominantly single-phase oxide, two phase oxide and oxide-carbon composite refractories by liquid silicate slags. Theoretical models of these processes, as well as static (sessile drop, dipping and crucible) and dynamic (rotating finger and rotary slag) experimental tests, along with their practical limitations are considered. Direct (co...
Hydrothermal Valorization of Steel Slags—Part I: Coupled H2 Production and CO2 Mineral Sequestration
A new process route for the valorization of BOF steel slags combining H2 production and CO2 mineral sequestration is investigated at 300°C (HT) under hydrothermal conditions. A BOF steel slag stored several weeks outdoor on the production site was used as starting material. To serve as a reference, room temperature (RT) carbonation of the same BOF steel slag has been monitored with in situ Rama...
Cancer of the eye in cattle with white faces occurs less frequently in cattle with pigmented eyelids. Corneoscleral pigmentation is related to eyelid pigmentation and occurrence of lesions that may precede cancer. Objectives of this study were to assess 1) variation in the proportion of eyelid and corneoscleral pigmentation in Hereford, Bos taurus, and Bos indicus crossbreds and 2) the occurren...
یکی از مهمترین تحولات در حوزه ی مدیریت استراتژیک که منجر به پیدایش انقلابی در حوزه ی راهبردی شده است،راهبرد اقیانوس آبی می باشد که با رویکرد تفکر راهبردی همراه با نوآوری در حوزه ی راهبردی اقدام به ارائه ی مجموعه ای از ابزارها و رویکردهای خاص جهت تحقق آن نموده است.امروزه دنیای نوین پوشاک و صنعت چرخ خیاطی مجموعه ای پررقابت است بر همین اساس این پژوهش طبق مدل استراتژی اقیانوس آبی(bos) به بررسی عوام...
In this study, slag penetration into a magnesia refractory monolithic was investigated by the crucible test method. A synthetic calcium aluminate slag system has been used to study commercial magnesia mix refractory for 1, 2, 3, 4, 5 and 6 hours at 1450°C and 1600°C. It has been shown that the penetration rate is controlled by a diffusion mechanism at 1450°C. In this case, capillaries are the ...
Bronchiolitis obliterans syndrome (BOS) is a major complication of lung transplantation that is associated with poor survival. The International Society for Heart and Lung Transplantation, American Thoracic Society, and European Respiratory Society convened a committee of international experts to describe and/or provide recommendations for 1) the definition of BOS, 2) the risk factors for devel...
