Aim. In order to optimize the diagnosis of pneumonia by including lung ultrasonography in the diagnostic algorithm for pneumonia, the main ultrasound signs of inflammatory infiltration of the lungs were identified, depending on the form of morphological substrate, and the capabilities of ultrasound examination in monitoring pneumonia were evaluated.Material and Methods. A total of 96 patients were admitted to hospital by emergency to rule out/to confirm pneumonia based on X-ray diagnosis of this pathology in 81 persons. Ultrasonic examination was performed in all patients at a day of admission to hospital. Dynamics in inflammatory infiltrate was evaluated in 55 patients at days 3–4, 7, and 10–14 of hospital stay.Results. The ultrasonic signs of inflammatory infiltrate were found in 55 of 96 patients with prevalent ultrasound pattern of pleuropneumonia (n=48; 50%) and bronchopneumonia in a smaller number of patients (n=7; 8.6%). The results of ultrasonography showed the low sensitivity (69.7%) and significantly high specificity (100%) rates of the method in detecting pneumonia. Positive dynamics in ultrasonic monitoring of pneumonia was detected in the overwhelming number of patients (n=45; 81.8%) at day 3 of hospitalization. Negative dynamics (n=3; 5.5%) was observed at days 3 and 7 of the study.Conclusion. Ultrasonic study may be considered a useful step in the diagnostic algorithm for patients with pneumonia as this method provides additional information for an attending physician and does not involve adverse effects of ionizing radiation on patient’s body. Since the ultrasonic data on positive and negative dynamics of pneumonia were received ahead of the results of standard control radiography and were verified by further clinical and radiological observations, the role of ultrasonic monitoring of the inflammatory infiltrate was essential for evaluation of the efficacy of antibiotic therapy at earlier time.

Aim. To assess the preoperative morphological state of the brain and the state of cerebral circulation in patients referred for coronary bypass surgery to identify predictors of long-term cerebral disorders.Material and Methods. The study included 33 male patients, divided into 2 groups according to the presence or the absence of distant neurological complications 5 years after surgery. All patients underwent non-contrast computed tomography of the brain and perfusion computed tomography. Computed tomography was repeated 5 years after surgery.Results. The perfusion indices in all measurement zones in patients of the two groups did not significantly differ. Significant differences in width of the third ventricle and ventricular-cranial index between patients of groups 1 and 2 were not identified. The incidence rates of leukoaraiosis significantly differed: leukoaraiosis was detected significantly more frequently in group 2 (78% of cases) than in patients of group 1 (31%), p=0.0455.Discussion. The dimensions of the brain cavity system and the preoperative state of the microcirculatory blood flow were not predictors of long-term postoperative neurological disorders. Five years after surgery, patients of group 2 showed clinical and morphological signs of past ischemic changes, which were not detected in patients of group 1 suggesting that leukoaraiosis was an unfavorable prognostic indicator of postoperative cerebrovascular disorders in the long-term period.Conclusion. When referring a patient with the presence of morphological manifestations of cerebral microangiopathy in the form of the leukoaraiosis phenomenon for cardiac surgery, these patients should be considered at risk requiring administration of the necessary set of measures for the prevention of long-term cerebral disorders.

Концессии в теплоснабжении: инвестиции вместо субсидий
Authors: Нефёдкин В. И. , Фадеева О. П. , Гинзбург Д. Р. 
Published: April 2019

<span>В статье рассматривается широкий круг проблем теплоснабжения в РФ и в Новосибирской области. Исследуются возможности и ограничения, связанные с применением концессий в качестве инструмента повышения эффективности и надежности теплоснабжения прежде всего в тех населенных пунктах, которые не привлекательны для крупных энергетических компаний. На основе изучения опыта концессий в теплоснабжении в Новосибирской области и интервью, проведенных с инициаторами и участниками проектов, авторы делают выводы как о первых практических результатах, так и о сопутствующих проблемах. В качестве примера рассматриваются проекты модернизации систем централизованного теплоснабжения в р.п. Маслянино и г. Обь. Первые результаты реализации данных проектов показали, что инвестиции со стороны федерального и регионального бюджетов позволили практически полностью отказаться от субсидирования теплоснабжающих организаций. Вместе с тем возможности тиражирования этого опыта из-за ряда институциональных и экономических причин ограничены. Наибольшие риски для потенциальных концессионеров связаны с практикой регулирования тарифов, базирующейся на «экономически обоснованных затратах», и высокими транзакционными издержками передачи в эксплуатацию частной стороне систем централизованного теплоснабжения, ранее обслуживаемых муниципальными унитарными предприятиями. Авторы предлагают использовать новые механизмы финансирования концессий в сфере теплоснабжения, которые могут существенно повысить привлекательность подобных проектов для частных инвесторов и заметно уменьшить потребность в текущих субсидиях из регионального и местных бюджетов на поддержку убыточных теплоснабжающих организаций.</span>

Fill Factor Effects in Highly-Viscous Non-Isothermal Rubber Mixing Simulations
Authors: Ahmed I. , Poudyal H. , Chandy A. J. 
Published: April 2019

AbstractA finite volume technique in a commercial computational fluid dynamics (CFD) code is employed in this study to simulate transient, incompressible, non-Newtonian and non-isothermal rubber mixing. The simulation processes are conducted in a two-dimensional(2D) domain, where a mixing chamber partially-filled with rubber is equipped with a pair of two-wing non-intermeshing counter-rotating rotors. The main objective is to assess the effect of different fill factors of rubber on dispersive and distributive mixing characteristics by simulating 15 revolutions of the rotors rotating at 20 min−1. 50%, 60%, 70%, 75%, 80% and 90% are the six different fill factors chosen for the study. An Eulerian multiphase method has been applied to solve for the two different phases, rubber and air. The non-Newtonian property of rubber is handled using the shear rate dependent Carreau-Yasuda model, along with an Arrhenius function to include the temperature dependency. In addition to the governing equations related to the conservation of mass, momentum and energy, the volume of fluid (VOF) method is chosen to track the interface between air and rubber. With regard to the results, flow patterns, thermal distributions, viscosity behavior and volume fraction are analyzed for the different fill factors. In addition, dispersive and distributive mixing behavior is also assessed in detail using Lagrangian statistics, such as mixing index, cumulative distribution of maximum shear stress, cluster distribution index (CDI), scale of segregation (SOS) and length of stretch (LOS), calculated from massless particles. Both the Eulerian and Lagrangian results showed that fill factors between 70% and 80% presented the most reasonable and efficient mixing scenario, and also exhibited the best dispersive and distributive mixing characteristics combined.

Published: April 2019

Abstract
Nanocomposites of polyvinyl alcohol (PVA) and Cadmium selenide (CdSe) were fabricated by ex-situ casting technique. CdSe nanoparticles were prepared by thermolysis under the flow of nitrogen. Rietveld refinement of x-ray data showed that the prepared CdSe adapts cubic zinc blend structure with a lattice parameter 6.057 Å and a mean grain size of 2 nm. Samples from CdSe/PVA nanocomposite have been exposed to infrared (IR) laser fluences in the range 0–19.6 J/cm2. The effect of IR laser radiation on the structural and optical properties of CdSe/PVA has been investigated using XRD and UV-vis spectroscopy. UV/VIS absorption spectra confirm the formation of hybridized film CdSe/PVA nanocomposite with refractive index in the range of 1.4119–1.8621 (at 700 nm). Also, the laser radiation reduces the optical energy gap from 4.1 to 3.43 eV which could be attributed to the increase in structural disorder of the irradiated CdSe/PVA nanocomposites due to the formation of coordination reaction between OH of PVA and CdSe nanoparticles. This means that the laser radiation led to a more compact structure of CdSe/PVA nanocomposite and causes proper dispersion of CdSe nanoparticles in the PVA matrix. Further, the Commission Internationale de E'Claire (CIE units x, y and z) methodology was applied in this work for the description of colored samples. The color intensity ΔE, which is the color difference between the non irradiated sample and the irradiated ones, was increased from 11.40 to 30.57 with increasing the laser fluence up to 19.6 J/cm2.

Housing and sanitation as one of the most essential human needs has always been at the top of human demands. Smart houses are among the latest achievements of the housing industry in the present era which have been taken into consideration in recent decades. The research method of this paper is descriptive-analytic. In the first part the paper deals with the definition of intelligent housing fields components functions. Also by objective observation and completion of the questionnaire information about the intelligent housing indices was collected. Using the AHP hierarchy technique the degree of physical vulnerability of residential units in the first district of Tehran has been determined; the results show that many residential areas are exposed to severe vulnerability. Also in order to answer the research hypothesis 30 professors and experts of the housing department were analyzed by the path analysis technique. The results of path analysis show that all factors have a direct and significant effect on reducing the vulnerability of urban housing. Separating direct and indirect effects of variables on reducing the vulnerability of urban housing shows that the safety and security agent with the highest value of 0.892 has the most direct, a positive and significant effect on reducing the vulnerability of urban housing. The remarkable thing about this factor is that the indirect effect of this agent through the factor of well-being and comfort is 0.863 which is very significant; in other words the factor of safety and safety through the factor of welfare and comfort will significantly reduce the vulnerability of housing. Also the direct effect of the comfort and comfort factor of 0.422 and energy savings of 0.398 significantly contribute to reducing the vulnerability of urban housing.

Sinilupiinin (Lupinus Angustifolius) vaikutus munivien kanojen tuotantoon ja munan laatuun
Authors: Tuunainen Petra , Koivunen Erja , Valaja Jarmo 
Published: April 2019

Sinilupiini on typpeä sitova palkokasvi. Sen viljelyä on tähän asti rajoittanut pitkä kasvuaika ja siitä aiheutuva viljelyepävarmuus, mutta valkuaisomavaraisuuden tehostamistavoitteet ovat viime vuosina lisänneet kiinnostusta sinilupiinin viljelyyn ja käyttöön rehuvalkuaisen lähteenä. Sinilupiinissa on kuitenkin vain vähän rikkipitoisia aminohappoja ja se sisältää paljon kuitua, mikä rajoittaa sen käyttöä siipikarjan ruokinnassa. Aikaisemmissa kokeissa sinilupiinin sulavuus ja muuntokelpoinen energia olivat broilereilla ja kalkkunoilla heikkoja verrattuna härkäpapuun tai herneeseen. Munivilla kanoilla lupiinilisäys ei vaikuttanut munantuotantoon, kun käyttötaso oli 15 %, mutta suurempi määrä vähensi selvästi munintaa. Tutkimuksen tarkoituksena oli selvittää rajoitetulla kanamäärällä sinilupiinin vaikutuksia munantuotantoon ja kanamunan laatuun, erityisesti keltuaisen väriin. Kokeessa oli 108 LSL- kanaa, jotka kokeen alkaessa olivat 40 viikon ikäisiä. Kanat jaettiin koehäkkeihin 3 kanaa per häkki. Koe kesti 6 viikkoa. Koeryhmien kanojen rehuihin lupiinia lisättiin 0, 8 tai 16 %. Kokeessa havaittiin, että kontrolliryhmän munintaprosentti oli huomattavasti pienempi kuin sinilupiiniryhmien munintaprosentit (P<0,0001). Munien tuotanto (g/pv/kana) parani lintujen syödessä sinilupiinia (P=0,019) ja samalla rehunmuuntosuhde (kg/muna-kg) pieneni (P=0,015), koska rehunkulutus (g/pv/kana) ei eronnut ryhmien välillä. Sinilupiinirehuilla ruokitut linnut munivat Haugh- luvultaan suurempia munia kuin kontrolliryhmä. Sinilupiinin määrällä ei havaittu olevan vaikutusta tuotantotuloksiin Tuotannon parantuminen saattoi johtua osittain eläinten välisestä vaihtelusta, ei niinkään sinilupiinin munintaa parantavasta vaikutuksesta. Sinilupiini näyttäisi kuitenkin maistuvan kanoille ja sopivan hyvin munivien kanojen valkuaisrehuksi. Sinilupiinia voidaan tämän kokeen perusteella käyttää munivien kanojen dieetissä ainakin 16 % ilman, että tuotantotulokset huononevat. Sinilupiinia syövät kanat voivat munia keltuaisen väriltään, punaisempi munia kuin tavanomaista rehua syövät kanat.
