Investigation of the steric structure of certain compounds of the bicyclo-[4,2,0]octan-7-one series
1. The steric structure of adducts of dichloroketene and cyclohexene, dichloroketene and methyl-cyclohexene, dimethylketene and dihydropyran was investigated by the methods of dipole moments and molar Kerr constants. 2. For all the adducts, the preferential conformation of the bicyclo[4,2,0]octan-7-one system is the anti-boat conformation. 3. The adduct of dimethylketene and dihydropyran has the structure of 8,8-dimethyl-2-oxobicyclo-[4,2,0] octan-7-one. The formation of such a structure is apparently determined by the electron donor influence of the oxygen atom in dihydropyran on the process of cycloaddition. Β© 1974 Consultants Bureau
Synthesis and structure of new N-alkoxy-N-(1-pyridinium)urea chlorides
New N-[1-(4-amino)pyridinium]-N-methoxyurea chloride, N-[1-(2-amino)pyridinium]-N-methoxyurea chloride and their analogs were synthesized by N-alkoxy-N-chloroureas reaction with the proper pyridines in acetonitrile or ether solution by improved procedure. XRD study of N-[1-(4-amino)pyridinium]-N-methoxyurea and N-[1-(2 amino)pyridinium]-N-methoxyurea revealed the elongation of N-N+ bonds and some shortening of MeO-N bonds, qunonoid deformation of pyridine rings compare to it unsubstituted analog. The substantial pyramidality of central nitrogen atom in O-N-N+ moiety and N-C carbamoyl bonds difference were established too. The structure summary of N-alkoxy-N-(1-pyridinium)ureas salts and other derivatives of 1-(N-alkoxyamino)pyridinium salts has been done
Non-Oberbeck-Boussinesq effects in turbulent thermal convection in ethane close to the critical point
As shown in earlier work (Ahlers et al., J. Fluid Mech. 569, p.409 (2006)),
non-Oberbeck Boussinesq (NOB) corrections to the center temperature in
turbulent Rayleigh-Benard convection in water and also in glycerol are governed
by the temperature dependences of the kinematic viscosity and the thermal
diffusion coefficient. If the working fluid is ethane close to the critical
point the origin of non-Oberbeck-Boussinesq corrections is very different, as
will be shown in the present paper. Namely, the main origin of NOB corrections
then lies in the strong temperature dependence of the isobaric thermal
expansion coefficient \beta(T). More precisely, it is the nonlinear
T-dependence of the density \rho(T) in the buoyancy force which causes another
type of NOB effect. We demonstrate that through a combination of experimental,
numerical, and theoretical work, the latter in the framework of the extended
Prandtl-Blasius boundary layer theory developed in Ahlers et al., J. Fluid
Mech. 569, p.409 (2006). The latter comes to its limits, if the temperature
dependence of the thermal expension coefficient \beta(T) is significant.Comment: 18 pages, 15 figures, 3 table

Aim. To study the rearrangement of Cooksonβs diketone by the action of potassium halides under conditions of polyphosphoric acid catalysis.Results and discussion. Chemical behaviour of Cooksonβs diketone (CS-trishomocubane-8,11-dione) in the reactions with potassium halides (KCl, KBr, KI) in the polyphosphoric acid (PPA) medium have been studied. When treated with the KI/PPA mixture Cooksonβs diketone undergoes reduction leading to tetracyclo[6.3.0.0.4,11.05,9]undecane-2,7-dione. The use of KBr instead of KI leads to formal addition of HBr to the cyclobutane ring of CS-trishomocubane-8,11-dione and gives 3-bromotetracyclo[6.3.0.04,11.05,9]undecane-2,7-dione. The general scheme of the cycle opening mechanism has been proposed. In the case of using the KCl/PPA mixture the reaction does not occur.Experimental part. The structure and composition of compounds were proved by the methods of 1H and 13C NMR-spectroscopy, and also X-ray diffraction analysis. Elemental analysis was performed for the compounds obtained.Conclusions. It has been shown that hydrohalic acids generated in situ under the reaction conditions do not induce the rearrangement of Cooksonβs diketone to the D3-trishomocubane system. The cyclobutane ring opening and reduction take place instead.Β Received: 12.12.2019Revised: 10.01.2020Accepted: 27.02.2020Π¦Π΅Π»Ρ.

Biocompatibility of Bare Nanoparticles Based on Silicon and Gold for Nervous Cells
This work aimed to investigate the biocompatibility of bare (ligand-free) lasersynthesized nanoparticles (NPs) based on silicon (Si) and gold (Au) with primary hippocampal cultures. 1%, 5% and 7% of culture medium were replaced by 0.1 mg/mL NP solution on day 14 of culture development in vitro. Our studies revealed that the NPs caused a dose-dependent cytotoxic effect, which was manifested by an increase the number of dead cells and a decrease of the spontaneous functional calcium activity of neural networks. Au NPs revealed less pronounced cytotoxic effect than Si ones and it can be explained by larger size and better solubility of Si NPs.

Radiative corrections to the cross section of and the crossed processes
Born cross section and the radiative corrections to its lowest order are
considered in the frame work of QED with structureless nucleons including the
emission of virtual and real photons. Result is generalized to take into
account radiative corrections in higher orders of perturbation theory in the
leading and next-to leading logarithmic approximation. Crossing processes are
considered in the leading approximation.Comment: 11 pages, 1 figur

Objective: to improve the results of treatment of patients with colorectal cancer complicated by acute bowel obstruction and diastatic rupture.Materials and methods. Retrospective analysis of treatment outcomes of patients with complicated colorectal cancer, treated at the Clinic of Hospital Surgery of theI.I.MechnikovNorth-WestStateMedicalUniversity from 1986 till 2015.Results. Of the 1206 patients with colorectal cancer complicated by intestinal patency violation injury breach of intestinal, decompensated violation intestinal patency (ABO) was detected in 245 (20.3 %) cases. The main principle of treatment of colonic obstruction in cancer was the intention for the simultaneous elimination of obstruction and the radical removal of the tumor. Radical surgery was performed in 152 (62 %) of 245 cases with ABO. In case of right-sided colon tumors generally colon resection with anastomosis formation were performed, in case of left-sided tumors colon resection in the majority ended with the terminal colostomy formation. Palliative operations were performed to 93 (37.9 %) patients. Postoperative complications were detected in 51 (20.8 %) cases. The death rate was 11.8 %. The mortality after radical surgical operations was 6.6 %. Diastatic rupture was diagnosed in 15 (1.2 %) patients. Subtotal colectomy with the formation or anastamosis was performed to 3 patients, operation ended with ileostomy formation β in 9 cases.Conclusion. In case of the left-side cancer of colon, complicated by ΠΠΠ, a radical surgical operation with colostomy formation is beneficial. In the case of colorectal cancer, complicated by the diastatic rupture the operation of choice is subtotal colectomy.Β Π¦Π΅Π»Ρ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ β ΠΎΠΏΡΠ΅Π΄Π΅Π»Π΅Π½ΠΈΠ΅ ΠΎΠΏΡΠΈΠΌΠ°Π»ΡΠ½ΠΎΠΉ ΡΠ°ΠΊΡΠΈΠΊΠΈ Π»Π΅ΡΠ΅Π½ΠΈΡ ΠΏΠ°ΡΠΈΠ΅Π½ΡΠΎΠ² Ρ ΠΊΠΎΠ»ΠΎΡΠ΅ΠΊΡΠ°Π»ΡΠ½ΡΠΌ ΡΠ°ΠΊΠΎΠΌ, ΠΎΡΠ»ΠΎΠΆΠ½Π΅Π½Π½ΡΠΌ Π΄Π΅ΠΊΠΎΠΌΠΏΠ΅Π½ΡΠΈΡΠΎΠ²Π°Π½Π½ΡΠΌ Π½Π°ΡΡΡΠ΅Π½ΠΈΠ΅ΠΌ ΠΊΠΈΡΠ΅ΡΠ½ΠΎΠΉ ΠΏΡΠΎΡ
