Insights into Sorption-Mineralization Mechanism for Sustainable Granular Composite of MgO-CaO-AlO-SiO-CO Based on Nanosized Adsorption Centers and Its Effect on Aqueous Cu(II) Removal.

Although copper is needed for living organisms at low concentrations, it is one of the pollutants that should be monitored along with other heavy metals. A novel and sustainable composite mineralizing sorbent based on MgO-CaO-AlO-SiO-CO with nanosized adsorption centers was synthesized using natural calcium-magnesium carbonates and clay aluminosilicates for copper sorption. An organometallic modifier was added as a temporary binder and a source of inovalent ions participating in the reactions of defect formation and activated sintering.

Application of Magnetic Force Microscopy for Investigation of Epitaxial Ferro- and Antiferromagnetic Structures.

Growing of epitaxial FeMn/Fe/Mo/R-sapphire films was performed with a new configuration of two in-plane easy axes of Fe(001)-layer magnetization in which application of annealing in a magnetic field forms an unidirectional anisotropy. The microstructures made from these films exhibited an exchange bias 25-35 G along an exchange field generated at antiferromagnet/ferromagnet (AFM/FM) interface. Magnetic force microscopy (MFM) experiments supported by micromagnetic calculations and magneto-resistive measurements allowed interpretation of the magnetic states of the Fe layer in these microstructures.

[The Effectiveness of Russian Public Health Recommendations for Sanogennykh Behavior in the Heatwave].

Unlabelled: There is an urgent need to create adapted for the Russian population of the recommendations in order to improve the efficiency and automation of the process of informing patients about the correct (sanogennykh) behavior in the heat. The proposed health WHO recommendations in 2010 year are difficult to perception, understanding and subsequent patient use without consulting a doctor.

The Goal: creating and testing adapted for the Russian population recommendations for sanogennykh behavior during the summer heat on the basis of the recommendations of the WHO in 2010.

[Impact of a cold wave on disease course, hemodynamics, carbohydrate metabolism, and blood rheological properties in cardiac patents].

Aim: To study the impact of cold waves on disease course, hemodynamics, lipid and carbohydrate metabolisms, oxidative stress, and blood rheological properties in patients with cardiovascular diseases (CVD).

Subjects And Methods: 24 men and 36 women (their mean age was 62.9±9.

[The ability to use meldonium as adaptogen in winter in patients with cardiovascular disease].

Given that the effects of frost can play the role of independent stress factor influencing the course of cardiovascular disease (CVD), it is reasonable to supplementation of drugs that increase the body's resistance to cold stress. Aim: To evaluate the possibility of using meldonium to prevent unwanted seasonal changes in CVD patients in the winter. The study included 49 patients with CVD aged 38-75 years.

Evidence for interacting two-level systems from the 1/f noise of a superconducting resonator.

The performance of a great variety of electronic devices--ranging from semiconductor transistors to superconducting qubits--is hampered by low-frequency noise with spectra proportional to 1/f. The ubiquity and negative impact of 1/f noise has motivated intensive research into its cause, and it is now believed to originate from a bath of fluctuating two-level defect states (TLSs) embedded in the material. This phenomenon is commonly described by the long-established standard tunnelling model (STM) of independent TLS.

[The diagnosis and treatment of injuries of the upper respiratory tract in wounds and traumas of the neck].

The authors made an analysis of results of treatment of 339 patients with wounds and closed injuries of the neck. Laryngotracheal injuries were found in 27 (7.9%) patients, in 15 patients the injuries being of combined character.

[Surgical strategy for wounds of the cervical part of the esophagus].

An analysis of results of treatment of 425 patients aged from 15 to 85 years with penetrating wounds of the neck was made. In 40 (8.1%) patients there were wounds of the cervical part of the esophagus, 29 of them had associated injuries.

[Acute tumorous obstruction of the colon in elderly and senile patients].

The authors present the results of surgical treatment of 106 elderly and senile patients. In 30 patients admitted in a extremely severe condition the acute intestinal obstruction was combined with peritonitis. Postoperative mortality in this group of patients was 86.

Laser action of trions in a semiconductor quantum well.

We report on the observation of optical gain and lasing at the trion transition of n-doped ZnSe quantum wells. Specifically, the (stimulated) emission-absorption net rate of this transition is controlled by the difference of trion and electron occupation in momentum space. As the mass of the trion is larger than that of the electron, gain occurs on the low-energy side of the line center without degeneracy and inversion in the total particle numbers.

[Collection of a concentration of hematopoietic stem cells from the umbilical cord ].

Allogeneic Hematopoietic Stem Cells Transplantation is a therapy for wide variety of malignant and nonmalignant disorders. Cord blood as an alternative source of hematopoietic stem cells was utilized and these transplantations.

[Case of necrotizing enteritis as the first symptom of systemic lupus erythematosus].

The aim of this work is to describe a case of necrotising enteritis as a first presentation of a systemic lupus erythematosus (SLE). The patient has undergone two laparatomies with resection of a part of the small intestine because of a clinically relevant intestinal obstruction. Distended intestinal loops, inflammed serosa and mesenterial lymphadentis have been found during the operations.

[The effect of a fluorocarbon emulsion--an enzyme inducer of the cytochrome P-450-dependent monooxygenase system of the liver--on the acute toxicity of CCl4 and on the efficacy of the prophylactic use of antidotes in organophosphate pesticide poisoning].

The effect of intraperitoneal administration of perfluorocarbon emulsion, an inducer of cytochrome P-450-dependent monoxygenase system of the liver, on the resistance of rodents to the action of CCl4 and organophosphorus pesticides was studied. Perfluorocarbon emulsion potentiated CCl4 toxicity decreasing LD50 from 4.5 to 3.

[Indicator tubes with a noncylindrical form for indicator packing].

A new type of system is made for determination of chemical pollutants in the air--indicator tubes with noncylindrical indicator filling--a subject of invention. The effect of the noncylindrical form on the metrological characteristics of the indicator tubes is studied. The noncylindrical filling is a way to influence these characteristics without changing the chemical receipt.
