Pathways resilient future for developing a sustainable E85 fuel and prospects towards its applications.

The utilization of ethanol as a component of motor gasolines is an extremely effective way to increase the detonation resistance and environmental properties. In Russia, despite the existing prerequisites for the development of bioethanol industry, the real production of bioethanol is not executed, which is associated with its high price. One of the promising ways of leveling this drawback is the utilization of water-cut waste from its production, involving ethyl alcohol impurity concentrate (EAIC) instead of pure ethanol.

New insights on introducing modern multifunctional additives into motor gasoline.

Multifunctional additives should be added into motor gasoline to raise the life of engine parts, increase the engine power, as well as reduce the exhaust emission and fuel consumption. This research article proposes new insights to produce modern multifunctional motor gasoline additives. The main components of these additives are detergents, corrosion inhibitors, and friction modifier.

Among different biofuels is introducing renewable fuel additives as prospective beneficial blendstocks towards fulfilling systematic, low-carbon technologies internal combustion engines. This research article proposes a new approach to formulate a Fuzzy modeling for examining various promising alternative renewable oxygenated compounds, including ethanol, isopropanol, MTBE, and 2-methyl furan into heavy hydrocracked gasoline a base fuel.

[Use of multiparametric magnetic resonance imaging in t-staging of prostate cancer: a multicenter study].

Aim: The study aimed to analyze the diagnostic performance of preoperative multiparametric magnetic resonance imaging (mp-MRI) in the staging of prostate cancer (PCa) versus postoperative histological examination and determine the most sensitive pulse sequence from the mp-MRI protocol in estimating the local extent of PCa.

Materials And Methods: The study comprised 112 men aged 52 to 84 years with a morphologically verified diagnosis of prostate cancer. All patients underwent pelvic mp-MRI before radical prostatectomy (RPE) no earlier than six weeks after the prostate biopsy.

[Comparative evaluation of the efficiency of different magnetic resonance imaging procedures in the recognition of local recurrence of prostate cancer: preliminary results].

The paper considers the role of different procedures of magnetic resonance imaging (MRI) of a local recurrence of the disease in patients undergoing radical prostatectomy (RPE) for prostate cancer (PC). A study group comprised 12 patients who had developed a biochemical recurrence with no evidence of systemic progression of the disease in different periods after RPE. All the patients underwent multiphase MRI using T1-T2-weighted, diffusion-weighted, and postcontrast images.

[Possibilities of using magnetic resonance imaging-transrectal ultrasound fusion in the diagnosis of recurrent prostate cancer].

This paper considers whether magnetic resonance imaging (MRI) and transrectal ultrasound (TRUS) can be fused, by applying an external bobbin with transrectal ultrasound imaging. The author has studied whether imaging fusion can be used to select a targeted needle biopsy (NB) portion if the development of recurrent prostate cancer (PC) is suspected after radical prostatectomy (RP). MRI-TRUS fusion was performed in 11 patients in different periods after RP.

Hemispheric aerosol vertical profiles: anthropogenic impacts on optical depth and cloud nuclei.

Understanding the effect of anthropogenic combustion upon aerosol optical depth (AOD), clouds, and their radiative forcing requires regionally representative aerosol profiles. In this work, we examine more than 1000 vertical profiles from 11 major airborne campaigns in the Pacific hemisphere and confirm that regional enhancements in aerosol light scattering, mass, and number are associated with carbon monoxide from combustion and can exceed values in unperturbed regions by more than one order of magnitude. Related regional increases in a proxy for cloud condensation nuclei (CCN) and AOD imply that direct and indirect aerosol radiative effects are coupled issues linked globally to aged combustion.

[The investigation of the composition of liquid radioactive waste].

In investigation the process of composition sediment of liquid unorganic radioactive waste, that are forming in cistern-selectors at PNPI RAS, it was discovered apart from great quantity of ions of different metals and radionuclides considerable maintenance of organic material (to 30% and more from volume of sediment) unknown origin. A supposition was made about its microbiological origin. Investigation shows, that the main microorganisms, setting this sediment, are the bacterious of Pseudomonas kind, capable of effectively bind in process of grow the radionuclide 90Sr, that confirms the potential posibility of using this microorganisms for bioremediation of liquid low radioactive wastes (LRW).

Particle nucleation in the tropical boundary layer and its coupling to marine sulfur sources.

New particle formation in a tropical marine boundary layer setting was characterized during NASA's Pacific Exploratory Mission-Tropics A program. It represents the clearest demonstration to date of aerosol nucleation and growth being linked to the natural marine sulfur cycle. This conclusion was based on real-time observations of dimethylsulfide, sulfur dioxide, sulfuric acid (gas), hydroxide, ozone, temperature, relative humidity, aerosol size and number distribution, and total aerosol surface area.

[Viral hepatitis A and the possible pathogenetic mechanisms of a protracted convalescence].

Metabolites of connective tissue (free serum oxyproline, protein-bound plasma oxyproline, total urine oxyproline, serum glycosaminoglycans), proteolytic enzyme elastase, proteolysis inhibitors (alpha 1-inhibitor, alpha 2-macroglobulin) were investigated in 103 patients with viral hepatitis A. It was established that connective tissue and its metabolites produce a negative effect on hepatocytic repair. Longterm convalescence is attributed to elastase hyperactivity in the presence of relative deficiency of proteolytic inhibitors.

[Effect of vitamins A and E on the contractile function of the heart in experimental myocardial infarction].

An experimental study in rabbits demonstrated that the animals treated with vitamins A and E (400 IU/kg and 0.4 mg/kg, respectively) in the presence of experimental myocardial infarction induced through ligation of the anterior descending coronary artery, showed a much more pronounced reduction of cardiac contractility as compared to the untreated animals with induced infarction or those treated with much higher doses (10000 IU/kg and 10 mg/kg, respectively). Vitamins A and E administered in small doses to intact animals and rabbits with experimental myocardial infarction produced marked damage of lysosome membranes, whereas high doses of vitamins had no similar effect in either intact or experimental-infarction animals.

Measurements of the humidification processes of hydroscopic particles.

A number of pure salt aerosols were produced in the laboratory, subjected to a controlled humidity environment. The magnitude of the electrooptic response was measured continuously over a range of relative humidity (RH), which was varied from 20 to 90%, with an integrating electrooptical nephelometer. From such observations the influence of water vapor on the salt aerosols, especially the process of phase transition that occurs at the deliquescent point, can be monitored.

Characterization of nonspherical atmospheric aerosol particles with electrooptical nephelometry.

An integrating nephelometer was adapted electronically to study the electrooptical properties of aerosol particles. The increase in light scattering coefficient due to orientation of nonspherical particles in the pulsed electric field and the decay of this signal were measured. Examples of the data for laboratory generated aerosols and atmospheric aerosols are presented.
