the effect of magnetic field on the liquid-liquid equilibrium of two ternary systems (water + acetic acid + butyl acetate and water + acetic acid + dimethyl succinate) at 298.15 k under atmospheric pressure was investigated. the results obtained show that the strength of the magnetic field (0.02 t) affects the solubility of acetic acid in the used organic solvents. distribution coefficients and...

The paper deals with the problem of developing a multi-output soft sensor for industrial reactive distillation process methyl tert-butyl ether production. Unlike existing approaches, this proposes using filters to predict model errors, which are then taken into account as corrections in final predictions outputs. decomposition optimal estimation time delays is proposed each input sensor. Using ...

We report a new method of fixation of osteochondral fractures using tissue adhesive butyl-2-cyanoacrylate. A traumatic osteochondral fracture of the patella and the medial femoral condyle in a 29-year-old male was fixed with butyl-2-cyanoacrylate tissue adhesive. At 6 month follow-up the fractures showed complete healing, the postoperative knee score was 84 and the functional knee score 90 (Kne...

Background. Injection with N-butyl-2-cyanoacrylate is a proven and successful therapeutic modality for treatment of patients with bleeding gastric varices. However, a variety of complications have also been associated with its use. Here, we report a rare case of retrogastric abscess which occurred almost six months after this therapy. This abscess was attributed to the hampered microbial cleara...

The asymmetric synthesis of the orthogonally funtionalised compounds tert-butyl 2-N-benzyl-N-alpha-methylbenzylamino-5-methoxycarbonylmethylcyclopentane- 1-carboxylate and methyl 2-N-benzyl-N-alpha-methylbenzylamino-5-carboxymethylcyclo- pentane-1-carboxylate by a domino reaction of tert-butyl methyl (E,E)-octa-2,6- diendioate with lithium N-alpha-methylbenzyl-N-benzylamide initiated by a Micha...

PURPOSE To verify the permanence of total occlusion of cerebral arteriovenous malformations after embolization with N-butyl cyano-acrylate and to evaluate the occlusion rate. METHODS One hundred thirty-four patients were treated for cerebral arteriovenous malformations with N-butyl cyano-acrylate embolization after superselective catheterization. Those initially totally occluded have been fol...

INTRODUCTION This case report describes an esophagojejunal anastomotic leak following total gastrectomy for gastric cancer. The leak was treated successfully with endoscopic application of n-butyl-2-cyanoacrylate. This is the first case report on the endoscopic application of cyanoacrylate alone for the treatment of an anastomotic leak. CASE PRESENTATION This report describes a case of a 68-y...

The crystal structure of the title compound, [Hf(C10H15)2(C4H9)2], reveals two independent mol-ecules in the asymmetric unit. The diffraction experiment was performed with a racemically twinned crystal showing a 0.529 (5):0.471 (5) component ratio. Each Hf(IV) atom is coordinated by two penta-methyl-cyclo-penta-dienyl and two n-butyl ligands in a distorted tetra-hedral geometry, with the cyclo-...

We report solid state (1)H nuclear magnetic resonance spin-lattice relaxation experiments and X-ray diffractometry in 2-t-butyldimethylsilyloxy-6-bromonaphthalene. This compound offers an opportunity to simultaneously investigate, and differentiate between, the rotations of a t-butyl group [C(CH3)3] and its three constituent methyl groups (CH3) and, simultaneously, a pair of 'lone' methyl group...

Among the few bacteria known to utilize methyl tert-butyl ether (MTBE) as a sole carbon source, Methylibium petroleiphilum PM1 is a well-characterized organism with a sequenced genome; however, knowledge of the genetic regulation of its MTBE degradation pathway is limited. We investigated the role of a putative transcriptional activator gene, mdpC, in the induction of MTBE-degradation genes mdp...
