Objective: Compared with the extensive data on left sided infective endocarditis, right-sided endocarditis (RSIE) remains a rare condition. It accounts for 5–10% of all cases (IE) [1] [2] [3].Although it is predominantly encountered in injecting drug user (IDU) population, where HIV and HCV infections often coexist, rheumatic heart disease most important predisposing factor IE our context....
In this investigation, the effect of zinc excess andits interaction with ascorbic acid on some growth parameters (root and shoot, fresh and dry weight, leaf blade area and length of root and stem), proline content, soluble sugars and starch plant were studied on canola. Experimental plants were treated with different concentrations of zinc sulfate ie. 0.7 (control), 50, 100, 250, 500 and 700 mM...
Information extraction (IE) for visually-rich documents (VRDs) has achieved SOTA performance recently thanks to the adaptation of Transformer-based language models, which shows great potential pre-training methods. In this paper, we present a new approach improve capability model on VRDs. Firstly, introduce query-based IE that employs span instead using common sequence labeling approach. Second...
Alkaloids are aromatic hydrocarbons with nitrogen as heteroelements in the ring structure that responsible for bonding metal surface and help to reduce corrosion of metals such mild steel (MS) an acidic medium. In this study, alkaloid Rhynchostylis retusa (RR) was extracted by solvent extraction method confirmed chemical test well FTIR spectroscopic test. Extracted alkaloids were tested green i...
In this paper, we investigate the solution of a two dimensional parabolic free boundary problem. The free boundary of this problem is modelled as a nonlinear integral equation (IE). For this integral equation, we propose an asymptotic solution as time is near to maturity and develop an integral iterative method. The computational results reveal that our asymptotic solution is very close to the ...
we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
BACKGROUND AND PURPOSE Staphylococcus aureus endocarditis showed an increase in the 1990s compared to the 1980s. In order to characterize the clinical and laboratory features of S. aureus endocarditis, we retrospectively reviewed the medical charts of patients diagnosed with endocarditis in the 5-year-period between 2000 and 2005. METHODS From August 2000 to August 2005, 22 patients with a de...
