Published: December 2018

BACKGROUND: The laser Doppler fluxmetry (LDF) is a non-invasive method to assess skin blood perfusion, measuring the flow of blood cells inside a tissue volume without harming the tissue. In the diagnosis of skin circulation disorders, the results of the LDF measurement are generally used in such a way that “normal” (or non-ill) or “pathological” values are achieved by comparison with a reference sample, for example of apparently healthy subjects. MATERIAL AND METHODS: In this study, the values of LDF for the diagnosis of microcirculatory disorders in patients with coronary artery disease ( n = 20) or in patients with microcirculatory disorders, already diagnosed by capillary microscopy ( n = 46), were examined. RESULTS: The mean values of LD amplitudes in the four frequency windows for patients with coronary artery disease were in the reference range. However, some of the patients showed reduced LD values: in eleven of the twenty patients, one or more mean LD amplitudes were below the reference range. Four of the eleven patients had pathologically decreased capillary erythrocyte velocities of very = 0.09–0.21 [mm/s], while the other seven patients had normal blood circulation at rest. For all patients with a proven cutaneous microcirculatory disorder, the mean LD amplitude in at least one of the frequency windows FF2 to FF4 was pathologically reduced. CONCLUSION: The Laser-Doppler fluxmetry method used in the study allows the reliable diagnosis of cutaneous microcirculatory disorders.

BACKGROUND: Pathomechanism and optimal renoprotective protocol for remote ischemic preconditioning (RIPC) have not been completely revealed yet. OBJECTIVE: To investigate micro-rheological effects of early and delayed RIPC in renal ischemia-reperfusion (I/R) in the rat. METHODS: In Control group the left femoral artery was cannulated and the left kidney was gently exposed. In the I/R group 45-minute renal ischemia with 120-minute reperfusion period was monitored. In the RIPC groups a 3×10-minute protocol was applied using tourniquet around the right hind-limb 1 hour (RIPC-1) or 24 hours (RIPC-24) prior to the I/R. Blood samples were taken for testing blood gas, acid-base, metabolic and hemorheological parameters. RESULTS: Lactate and potassium concentration significantly increased in I/R that could be reduced by RIPC, especially in RIPC-24. Creatinine concentration increased further in RIPC groups. I/R and RIPC-1 decreased the pH, RIPC-24 increased. RIPC-24 reduced the drop in base excess. Erythrocyte deformability worsened by renal I/R. In RIPC groups deformability decreased additively. However, RIPC-1 could improve the condition. RIPC-24 showed the highest erythrocyte aggregation values during reperfusion. CONCLUSIONS: Renal I/R worsened metabolic and micro-rheological parameters that could be modulated by RIPC protocols. However, it could not be decided whether the early or the delayed protocol is better.

Background: Time and resource limitations prevent cognitive assessment in acute-to-subacute settings, even in comprehensive stroke centers. Objective: To assess cognitive function in acute stroke patients undergoing routine clinical, laboratory, and radiological investigations, with a view to improving post-stroke care and treatment. Methods: Sixty-nine patients (72.6±11.1 years; 65% male) were prospectively enrolled within 14 days of acute ischemic stroke. Patients with altered consciousness, aphasia, or dysarthria were excluded. Clinical features including modified Rankin and NIH stroke scales, and vascular risk factors were assessed, as well as neuroimaging parameters by semi-quantitative evaluation of medial temporal lobe atrophy (MTLA) using MRA source images, FLAIR images for white matter changes (Fazekas scores), and T2∗ images for cerebral microbleeds. Neuropsychological screening was conducted using the Montreal Cognitive Assessment (MoCA) test. Univariate and multivariate analyses were used to evaluate the influence of variables on MoCA total and subscale scores. Results: Lower MoCA scores of 22 or less were associated with MTLA [OR (95% CI), 5.3 (1.0–27.5); p = 0.045], education years [OR (95% CI), 0.71 (0.55–0.91); p = 0.007], and modified Rankin scale at discharge [OR (95% CI), 2.4 (1.3–4.5); p = 0.007]. The delayed recall MoCA score was correlated with MTLA ( r = – 0.452, p < 0.001), periventricular ( r = – 0.273, p = 0.024), and deep ( r = – 0.242, p = 0.046), white matter changes. Conclusions: MTLA, together with lower educational history, are quick indicators of amnestic cognitive impairment after stroke. The association between cognitive impairment and physical disability at discharge may signify the importance of earlier cognitive assessment.

For safe and effective operation of a blast furnace it is important to know the residual thickness of the blast furnace hearth lining any time, first of all the location of the damaged arears. Use of traditional methods of hearth and bottom lining control often lead to a mistaken diagnostics.Institute of metallurgy of Ural branch of RussianacademyofScienceselaborated a mathematical model, providing a 3-dimentional estimation of the lining status and optimization of calculations for operation in real time mode.The calculation is done by solving equations of heat conductivity by usage of a number of temperature sensors (up to 700), implemented into furnace lining between refractory blocks. Calculation algorithm was modified by application of sampling theorem to take into account the complex profile of the blast furnace lower part. A system of information collection, processing and passing used from the sensors to program data base. A continuous control of temperature variation in every point enables to determine a current lining refractory thickness and notify the furnace personal in advance about beginning of the lining erosion. The elaborated program interface enables the furnace foreman to use additional control functions, in particular, the residual lining thickness, including: direct visualization of the status and tendencies of the erosion change, temperature distribution in every point of the lining at computer monitor, signaling about dangerous zone; volume temperature distribution (isotherms) and tendencies of their changes. The interface languages available as following: Chinese, English, Russian.

Authors: Yur’ev B. P. , Dudko V. A. 
Published: December 2018

A blast furnace technology developed, using equally basicity Kachkanar iron ore raw materials. Research work carried out to study gas media content and pellets basicity influence on their structure and metallurgical properties, as well as basicity and fuel content in the burden influence on metallurgical properties and structure of sinter. It was determined, that usage of low basicity pellets and high basicity sinter with weak rupture during reduction, provide a high gas penetrability in the upper horizons of blast furnace.It was shown, that presence of amphoteric titanium oxides and aluminum in Kachkanar sinter and pellets, as well as decrease of slope angle of the shaft in blast furnace prevents the early sticking of burden materials in the lower horizons of the furnace, that provides smooth burden lowering, high degree of gas reduction potential usage and thus the increase of the furnace productivity as well as coke rate decrease.An analysis of the work to optimize the technology of pellets production of Kachkanar concentrates made. It was determined, that an increase of the pellets quality can be reached as a result of implementation of a technology of their roasting with a partial dissociation of hematite. A complex estimation of metallurgical properties of partially dissociated pellets carried out. It was shown, that the pellets with hematite-magnetite structure, being a result of partial dissociation of hematite, are reduced at higher temperatures, when their intensive swell and rupture at the stage of hematite-into-magnetite transfer do not happen.

Modification of alloys, in particular, by calcium and barium, is one of the promising directions for obtaining alloys with a fine crystalline structure. Complex ferroalloys – ferroalumosilicocalcium and ferrosilicobarium – were developed in the Chemical and Metallurgical Institute after Zh. Abishev. It was shown, that modification of steel by silicon-aluminum complex alloys containing chemically active elements – calcium and barium, should become one of the most effective methods to improve the quality of machine-building metal products.The chemical compositions of the smelted ferroaluminosiliconcalcium and ferrosilicobarium presented. The melting range of the nonmetallic compound formed during the deoxidation of steel by complex alloy containing calcium determined. Results of mechanical tests of the specimens of steel, modified by a complex alloy containing barium considered. A comparison of microstructure of the current production route steel and deoxidized with the complex alloys was carried out.In the course of metallographic studies of experimental steel specimens, a modifying influence on the morphology of nonmetallic inclusions by calcium and barium, supplied in a complex with aluminum and silicon alloys, was established.Metal processing by complex alloys such as ferrosilicoaluminum with calcium (FASC) and ferrosilicobarium (FSAB) indicates the possibility of achieving a higher degree of refining from oxide nonmetallic inclusions and a more even distribution of them in the ingot.The results of the industrial heats also indicated a possibility of improving of quality of casting through the decreasing of hot thermal cracks and gas-shrinkage defects, cleaner grain boundaries, a significant reduction in the number and size of carbide inclusions.

English Title:Crime and socialisation dynamics in sub-cultures: Case of Gypsies in KaramanAbstractIn this study, the relationship between crime and the socialization process in Gypsy subculture is examined. This is is a qualitative study analysing the relationship between crime and the socialization process among Gypsies in different parts of Karaman between the years 2014-2015, especially the “Yeni” neighborhood known as Abdali district. In-depth interviews helped us to group Gypsy families into four different family types. It can be said that during unique socialization process of Gypsy subculture, Gypsy individuals’ attitudes to crime is shaped in the context of its unique dynamics through their families, relatives and friends. Unlike other social groups, the Gypsy subculture allows forming a habitus conducive to be involved in crime. Although they have common social characteristics with Gypsies living in different parts of Turkey, Gypsies in Karaman have a distinctive lifestyle and habitus due to their unique socialization process.Keywords: Gypsy; crime; culture; religion; socialization ÖzetBu çalışmada Çingene alt kültürü içerisindeki toplumsallaşma sürecinin suç ile ilişkisi incelenmektedir. Nitel bir çalışma olarak tasarlanan bu çalışma 2014-2015 yılları arasında Karaman’ın Abdal Mahallesi olarak bilinen Yeni Mahalle başta olmak üzere farklı bölgelerinde yaşayan Çingenelerin toplumsallaşma süreçleri içerisinde suç ile ilişkilerini sosyolojik olarak analiz etmeyi amaçlamaktadır. Bu çalışmada Çingene aileleri karakteristik özelliklerine göre dört farklı aile tipi şeklinde sınıflandırılmıştır. Araştırmada Çingene alt kültürünün kendine özgü toplumsallaşma süreçleri içinde Çingene bireylerin suç ile ilişkilerinin onların aile, akraba ve arkadaş çevresi ile ilişkileri bağlamında kendine özgü dinamikleri içinde şekillendiği görülmektedir. Diğer toplumsal kesimlerden farklı olarak Çingene alt kültürü kendi içinde suçun üretilmesini sağlayan bir habitusun oluşmasına imkan vermektedir.

Shaping the Verisimilitude: Moral Didacticism and Neoclassical Principles Responsible for the Rise of the English Novel?
Authors: Golban Petru 
Published: December 2018

The rise of the novel is a major aspect of the eighteenth century British literature having a remarkable typology: picaresque, adventure, epistolary, sentimental, of manners, moral, comic, anti-novel. The comic (including satirical) attitude, social concern, moral didacticism, and other thematically textualized aspects – emerging from both picaresque tradition and neoclassical principles – and together with picaresque tradition and neoclassical principles – are responsible for the emergence of verisimilitude as the forming element responsible in turn for the rise of the literary system of the novel.
A Study on the Sociology of Pierre Bourdieu and Conducting Social Research with Gypsy / Roma Groups
Authors: Gezgin Elif , Greenfields Margaret 
Published: December 2018

In social science discourse, the dichotomy between agency and structure tends to dominate debates pertaining to identity construction. When complex social facts are viewed through a simplistic prism of either individual activities or dominant structural impacts is likely to lead to a conclusion, - particularly when the subjects of research are members of communities at risk of vulnerability which are merely two-dimensional; omitting essential elements and interplays of circumstances, agency and structures which can rapidly shift dependent on both personal and external contexts and stressors. In this article, we discuss ways of utilising Pierre Bourdieu's theoretical model to explore the potential for creating a more nuanced theory of identity construction in the context of case studies focused on Gypsy/Roma(ni) people, whose identities depend both on internal identifications and those of the (dominant) groups with whom they live. We also aim to consider how in two widely contrasting international contexts – that of Roma people in Turkey and Gypsy/Traveller communities in the UK – use of Bourdieuian analysis provides appropriate tools that enable an analysis of daily living and the associated sense of active agency of these populations without minimising or excluding the structural effects which impact them. This approach enables a nuanced relational approach to understanding Gypsy/Roma(ni) groups’ identity construction in its entirety, whilst taking account of the specific geographical context in which the populations reside.
