MATHEMATICAL MODELLING OF THE TECHNOLOGY OF PROCESSING THE SEED MASS OF VEGETABLES AND MELONS
Authors: Shebanin V. , Atamanyuk I. , Gorbenko O. , Kondratenko Y. , Dotsenko N.
Published: November 2019

Designing modern seed processing machines requires a study of the regularities of technological processes, dynamics and conditions of operation. To determine the control parameters and their optimum values, it is necessary to use high-precision mathematical models of technologies of processing the vegetable and melon seed mass. A method has been suggested of modelling the technology of processing the seed mass of vegetables and melons based on nonlinear canonical decomposition of a random sequence of changes in the technological process parameters. The method of modelling the technology of processing the seed mass of vegetables and melons can be used to determine the optimum values of design and operation parameters of seed separating machines. This method allows obtaining mathematical models of technological processes for an arbitrary number of input parameters used to evaluate the characteristics of seeds, the degree of nonlinearity, and the peculiarities of stochastic connections. The method consists of the following stages: collection of statistical data; calculation parameters in the mathematical model; evaluation of the values of the parameters; calculation of the input parameters. The mathematical model of the processing technology of the seed mass of vegetables and melons does not impose any restrictions on the properties of the random sequence of input and output parameters (linearity, stationarity, monotonicity, scalarity, etc.). It allows taking into account the features of seed processing and, as a result, achieving the maximum quality of separation of vegetable and melon seeds. The method has been approved on the basis of the experimental installation of a separating machine. The results of the experimental studies have confirmed the high accuracy of the suggested method. The application of the suggested models reduces the average error of determination of seed losses. Statistic data for calculating mathematical model parameters have been obtained in the course of processing melons and cucumbers on an experimental installation. The results of the experimental studies have confirmed the high accuracy of the suggested method.
Gender Affirming Voicework: An Introduction for Music Therapy
Authors: Gumble Maevon
Published: November 2019

Informed by personal experiences, my queer autoethnographic research, and literature from the fields of speech-language pathology, vocal pedagogy, and music therapy, I offer an introduction to gender affirming voicework in music therapy, the training that it might involve, and several questions/issues that need further exploration. As a new holistic method grounded in a queer theoretical framework, I envision this work to be a therapeutic space focused on accessing and embodying affirming gender expressions by working with the intersections of the physical voice, the psychological voice, and the body as these each become relevant to an individual. This work involves the use of singing, vocal improvisation, chanting, toning, movement, imagery, and relaxation experiences to address areas of vocal function and emotion/identity. Stigma and trauma can come with living in this incredibly gendered and binary world. As such, gender affirming voicework emphasizes radically and queerly listening to our own vocal, psychological, and bodily expressions and the ways these fluidly shift from moment to moment. This is in efforts to speak, sing, move, and live in the most affirming and authentic way we can.
Playing in the Borderlands: The Transformative Possibilities of Queering Music Therapy Pedagogy
Authors: Fansler Vee , Reed Rachel , Bautista Ezequiel , Arnett Ashley Taylor , Perkins Freddy , Hadley Susan
Published: November 2019

Music therapy pedagogy has traditionally been defined by rigid roles and structures, including fixed teacher/learner identity categories, systematized hierarchies of knowledge and communication, cultural and musical gatekeeping practices, and standardized musical, clinical, and professional competencies. These structures represent narrowly defined borders, which limit who enters the profession, how we understand human variability, and whose knowledges are acceptable within the field of music therapy.

This article challenges educational stakeholders to destabilize long-held oppressive categorizations and move into generative liminal spaces as an opportunity to experience radically inclusive relationships. We believe that these relationships are key to the transformative learning process of understanding ourselves, others, and the worlds we inhabit. We engage queer theory literature to establish key tenets of “queering” as an active practice applicable beyond gender and sexuality to include other socially constructed identity categories such as race and disability. We then move beyond identity categories themselves to address systemic educational and institutional practices. We draw from Gloria Anzaldúa’s concept of borderlands as a generative space of liminality, deconstructing the borders that limit full, authentic access to and within spaces of teaching, learning, practicing, communicating, working, relating, musicking, moving, and living; Maria Lugones’ concept of “world” traveling, loving perception, and playfulness; Luce Irigaray’s concept of wonder; and Carolyn Kenny’s writings on the field of play that illustrate that when we play in music therapy, there is a need for containers and boundaries that are open to multiple, fluid ways of being and ways of being in relationship.

The structure and electrical properties of (FexOy)10 (ZnO)90 ceramics (0 ≤ x ≤ 3; 1 ≤ y ≤ 4) synthesized in air by one− and two−stage method were studied. To dope ZnO, powders of FeO, α−Fe2O3, and Fe3O4 or a mixture (α−Fe2O3 + FeO) were used. On the basis of X−ray diffraction analysis, gamma−resonance spectroscopy and Raman spectroscopy, it was established that at fixed average iron concentrations of 1—3 at.% in ceramic samples, at least three phases are formed: solid solution Zn1−δFeδO with wurtzite structure and residual iron oxides FexOy, used as doping agents. Scanning electron microscopy and energy−dispersive X−ray analysis have shown that, in the studied ceramics, the grain sizes of the wurtzite phase decreased from several tens of micrometers using one−step synthesis to the submicron level for the case of two−step synthesis. It was found that the incorporation of iron into ZnO leads to a contraction of the crystal lattice in the wurtzite phase and the stronger, the higher the proportion of oxygen in the doping iron oxides FexOy. The study of the temperature dependences of the electrical resistivity have shown that deep donor centers with an activation energy of about 0.35 eV are formed in the wurtzite phase Zn1−δFeδO. The temperature dependences of the electrical resistivity in the undoped ZnO in the temperature range of 6—300 K and in the doped ceramics (FexOy)10(ZnO)90, obtained by the one−step synthesis method, at temperatures below 50 K, are characterized by a variable activation energy, which indicates a strong disordering of their structure.

Abstract. In this paper, the effect of Al3+ ions substitutions on the value of the effective magnetic anisotropy field НАeff and the degree of magnetic texture f of the anisotropic polycrystalline hexagonal barium and strontium ferrites were studied. The samples were obtained by the ceramic technology method and the texture was formed by pressing in a magnetic field. The sample preparation technology presented in detail. The batches of barium hexaferrites were synthesized with the concentration of Al3+ ions: 0.9; 1.4; 2.5 and 2.6 formula units while strontium hexaferrites had Al3+ concentration of 0.1 formula units. It has been shown that by this technology barium and strontium hexaferrites with high value of (in range of 19—35 kOe) and with f = 80—83% could be obtained. The achieved values of НАeff and f could be sufficient for the production of substrates for microstrip microwave devices in millimeter−wave region.For the first time a raise in the degree of magnetic texture of polycrystalline barium hexaferrites with an increase of concentration of Al3+ ions were detected; a slight (5.5—5.8%) magnetic texture of isotropic strontium hexaferrites was also detected. The achieved results discussed in detail. For studied hexaferrites the mechanism of magnetic texture formation during the process of synthesis is proposed.
10X Genomics Single-Nucleus RNA-Sequencing for Transcriptomic Profiling of Adult Human Tissues v1
Authors: Lake Blue
Published: November 2019

10X Genomics Single Cell 3' (v3) RNA sequencing is a microdroplet-based method that permits the effective capture and sequencing of the mRNA and pre-mRNA molecules from single nuclei [1]. RNA molecules are transcribed and processed within the nucleus before exporting to ER for translation into proteins. As such, nuclear RNA is a mixture of nascent transcripts, partially or fully processed mRNA, and various non-coding RNA molecules. The total RNA content within the nucleus is roughly 10% of the RNA content in a whole cell, but has been found to accurately represent whole cell expression values in adult human tissues [2,3] including the kidney [4]. Nuclei can be readily isolated from frozen tissues with a combination of chemical and physical treatments that can effectively circumvent the non-uniform or incomplete dissociation of solid tissues into single cells, as well as RNA degradation or artefacts (such as stress response) during dissociation. Here we present a modified version of the published 10X protocol [1] that we have adapted for the processing of adult human kidney nuclei. References 1.

Published: November 2019

The ability of producing of effective carbon sorbents from abies bark with the use of thermal alkaline activation in presence of potassium hydroxide was shown. The effects of ratio of bark to alkaline, and temperature of bark pre-carbonization on the porous structure and sorption properties of the carbon sorbents were studied. It was shown, that the capacity of carbon sorbents on iodine is defined by pores with a width 0,73–1,86 nm, on methylene blue – 0,86–2,95 nm, and on vitamin B12 – ≥ 9,31 nm. It was determined, that the carbon sorbent, producing by alkaline activation of product of abies bark carbonization at 400 °С, has a high sorption capacity for studied marker substances. For this sorbent kinetic of iodine, methylene blue and vitamin B12 sorption was studied in comparison with the simple of commercial active coal for medical purposes. It was determined, that this sorbent exceeds the commercial sample in sorption of iodine and vitamin B12 in 1,5 time, and at sorption of methylene blue – in 1.7 time, and it is characterized by a higher rate constants of their markers sorption

Authors: González Buitrago José Ignacio
Published: November 2019

El estudio identifica los mecanismos jurídico-administrativos que el Estado colombiano ha implementado o debe implementar para hacer su estructura administrativa más flexible y, en consecuencia, más efectiva, eficiente y garantista. Describe cómo operan cada uno de ellos y, a su vez, observa el cumplimiento de los compromisos que debe acatar el Estado en el marco de los vigentes procesos de internacionalización y globalización. En tres grandes acápites se hace referencia a la delimitación de los conceptos de globalización, sociedad de la información y sociedad del conocimiento, para luego asumir la modernización del Estado desde dos aspectos: el nuevo enfoque de la gerencia pública y el concepto de gobierno electrónico (e-gobierno) o gobierno en línea, para el caso colombiano. Finalmente se describen los mecanismos jurídico-administrativos que optimizarían la flexibilización de la gestión y estructura del Estado. En este punto, se dedica una sección a determinar los dispositivos jurídico-administrativos implementados por el gobierno colombiano dentro de la estrategia de Gobierno en línea.
A propósito de la “fundamentalidad” del derecho a la vivienda. La experiencia Argentina
Authors: Kurlat Aimar José Sebastián
Published: November 2019

Muchas veces se ha dicho que el derecho a la vivienda es un derecho fundamental y, ciertamente, lo es. En este trabajo nos interrogamos sobre aquello que otorga jurídicamente la nota de la fundamentalidad a tal derecho desde una doble perspectiva: doctrinal y normativa. El derecho a la vivienda, efectivamente, puede asociarse a dimensiones tales como la igualdad real, el normal ejercicio de la ciudadanía, la autonomía y la dignidad de la persona. Estas aristas se encuentran en textos normativos y en la jurisprudencia en todos los niveles.

In this sense, the present research is aligned with the principles of Sustainable Development agreed at Rio de Janeiro, in 1992.
Attraction and repulsion forces in melt-textured and sintered YBCO-superconductors: a comparative study
Authors: Arias-Arana Diego Andrés , Rojas-Zambrano Juan Diego , Mariño-Camargo Álvaro
Published: November 2019

In this paper, we measure the attraction (suspension) and repulsion (levitation) forces produced by the interaction between a permanent magnet and different bulk superconductors. The measurements of the interaction force HTS-PM were carried out with a relatively simple technique developed by us, which is reproducible, reliable and low cost. The obtained results were analyzed with the Bean’s critical-state model assuming a uniform magnetic field applied to the superconductor. Two superconducting samples of YBa2Cu3O7-δ (YBCO) prepared by solid-state reaction method and by the melt-textured growth method (MTG) were used. Both samples presented a different hysteresis behaviour in the field cooling (FC) and zero field cooling (ZFC) regimes. Levitation and suspension phenomena were observed in the MTG sample; however, the sintered sample (S) with Oxygen deficiencies (δ > 0.15) displayed a slight levitation force but did not show a suspension force, the latter one attributed to a more efficient magnetic flux pinning. Additionally, the critical current density of both samples was determined from the maximum gap of the force (ΔF) in the FC regime. The obtained values were between 43.00 A/cm2 and 2,758 A/cm2 for the sintered and MTG samples, respectively. These values show a remarkable difference between sintered and MTG samples like that observed from magnetization measurements, which indicate that attraction and repulsion force measurements could provide a rapid and reliable characterization method of polycrystalline superconducting samples.
Effect of the viscous damping on the seismic response of Low-rise RC frame building
Authors: Baba-Hamed Fatima Zohra , Davenne Luc
Published: November 2019

The equivalent viscous damping is a key parameter in the prediction of the maximum nonlinear response. Damping constitutes a major source of uncertainty in dynamic analysis. This paper studies the effect of using viscous damping, on the reduction of the seismic responses of reinforced concrete RC frame buildings modeled as three-dimensional multi degree of freedom (MDOF) systems, and the use of nonlinear time history analysis as a method of visualized behavior of buildings in the elastic and inelastic range. This study focuses on the implications of the available modeling options on analysis. This article illustrates the effect of using the initial or tangent stiffness in Rayleigh damping in analysis of structures.  Correspondingly, this work is also concerned with the estimation of Rayleigh, mass-proportional or stiffness-proportional damping on engineering demand parameters (EDPs). As a result of a series of considerations, a damping modeling solution for nonlinear time history analysis (NLTHA) was carried out to compute the damage index. The application example is a building designed according to reinforced concrete code BAEL 91 and Algerian seismic code RPA 99/Version 2003 under seven earthquake excitations. The simulations demonstrated the accuracy and effectiveness of the proposed method to account for all of the above effects.
La archivología en el contexto de la sociedad interconectada por redes
Authors: Blanco-Rivera Joel Antonio
Published: November 2019

La sociedad interconectada por redes ha generado un aumento vertiginoso en información de origen digital. Además, la información es creada, compartida y manejada a través de sistemas complejos de comunicación. Ante esta realidad, archivistas han cuestionado la pertinencia de teorías y prácticas archivísticas para el manejo adecuado de esta información. Este artículo estudia las implicaciones de esta sociedad interconectada a la teoría y práctica archivística, con un enfoque en los contenidos de las redes sociales. Se argumenta que si aceptamos que los archivos son constructores de las memorias de la sociedad y agentes para la documentación de la experiencia humana, entonces debemos reconocer que la información generada a través de las redes sociales es parte de esa experiencia humana, y, por tanto, es importante considerar su selección y preservación. Finalmente, a través de dos ejemplos, la preservación de los archivos de redes sociales de la presidencia de Barack Obama y la creación de una colección de tuits sobre la huelga de la Universidad de Puerto Rico, se identifican desafíos y oportunidades en su tratamiento.

Modern advances in oncology can achieve significantly better results in terms of life expectancy in patients with metastatic brain disease. The combination of surgery, systemic therapy, whole brain irradiation and local methods of radiation therapy lead to good indicators for controlling the manifestations of the disease in the brain. Of course, intensification of treatment increases the risk of iatrogenic complications. The use of aggressive stereotactic radiotherapy regimens leads not only to high local control of irradiated metastases, but also to the risk of so-called radiation necrosis. The use of the most up-to-date diagnostic methods does not always allow one to unequivocally differentiate radiation necrosis from continued metastasis growth. The above example shows the need for a careful assessment of such situations and a multidisciplinary approach to interpreting the results of stereotactic radiotherapy.

CHANGING EVERYDAY PRACTICES IN SUBURBAN SPACES: A METHODOLOGY TO INVESTIGATE LOCAL TRENDS
Authors: PROVOTAR Natalia , MELNYCHUK Anatolii , GNATIUK Oleksiy , DENYSENKO Olena
Published: November 2019

Urban and suburban spaces are social and multidimensional. The city and its suburbia constitute an arena of diverse and conflicting social processes. Their social differentiation is manifested, first of all, in housing segregation and diversity of various types and forms of life activity. Social interactions and relationships between individuals and social groups take place in the social space of the city and the suburbia. Their behavioural practices lie at the intersection of economic, social, cultural, environmental, and urban planning domains of urban functioning and manifest themselves in everyday practices. The concepts addressing the research of everyday practices were designed and tested in the fields of sociology, history, and economy. The goal of this article is to develop a methodology for the study of local trends of changing everyday practices in suburban spaces of cities with different functions on the bases of human geography and urban science. The authors propose to study everyday social practices using actor-network theory, making possible to consider the variability of everyday practices of suburban residents as a network of interaction between actors (people, non-people, and ideas) that create, act and change. The initial phase of the research involves a general analysis of the processes and paradigms of suburban development of model cities by analysing scientific literature, field trips to selected suburban areas, use of remote sensing data and local media screening. Based on this analysis, the cases (test areas) are determined. The analytical stage of the study tries to identify characteristics, factors and trends of the temporal changes in the everyday practices of the population of selected areas, focusing on the everyday practices of leisure and self-organization. This stage of the study involves comparative historical and comparative geographical analysis, mapping, in-depth interviews, as well as field observations. The ending stage aims at identification of current trends and peculiarities of changing everyday practices in ambiguous suburban spaces and developing recommendations for local governments and planning agencies.

Published: November 2019

Con el presente artículo se busca proponer una visión sobre los fundamentos y los límites de las reglas especiales de sujeción de las Fuerzas Militares al Estado y al pueblo, teniendo en cuenta el significado y el alcance del concepto de soberanía consagrado en el preámbulo y en el artículo 3 de la Constitución Política.

Las reglas de sujeción imponen restricciones a todos los integrantes de la sociedad, sin embargo, existe un conjunto de personas cuyas limitaciones son superiores, como el caso de los servidores públicos y en especial los miembros de las Fuerzas Militares.

Para realizar esta investigación, se propone realizar un análisis que parte del concepto de soberanía y su ejercicio en cada una de las dimensiones en las cuales puede ser observada, para tratar de determinar en qué punto se relacionan y desde donde se fijan los factores esenciales para considerar como está sometida la institución encargada de defenderla.

De igual manera, se hará un abordaje desde los mecanismos de participación ciudadana consagrados en la Constitución de 1991 y como a pesar de estipularse para todos los ciudadanos, los miembros de las Fuerzas Militares no pueden ejercer los mismos a plenitud, en virtud de la sumisión y sometimiento al soberano, visión que nos permitirá establecer también el límite de la sujeción de los militares respecto de los mandatarios y sus mandantes.

Authors: Kareem Tayeb S. , Farman Renas A.
Published: November 2019

Background & Aim: The port site hernia is a type of incisional hernia that occurs at port sites after laparoscopic surgery. Various factors have been implicated in the development of port site hernia.

The aim of this study was to know the risk factors of the port site hernia.

Patients & Methods: A retrospective study of patients who underwent different elective laparoscopic procedures in Rizgary Teaching Hospital in Erbil in a period from March 2013 to September 2014.

Results: Out of 300 patients only 8 (2.7%) patients developed port site hernia. The time of the hernia occurrence ranged from 3 weeks to six months postoperatively. Half of the hernias were found in cases of age group (60-80) years. Six (75%) of the cases were female patients. All 8 hernias developed after laparoscopic cholecystectomy. Six (75%) hernias developed after open port entrance technique. All hernias occurred when the fascia in 10 mm port was not closed. Seven hernias (87.5%) occurred in patients with BMI ranged (25-34).

Conclusion: Age of the patients, technique of entrance, site and size of the port with unclosed fascial layer are important factors for developing port site hernia.

An analytical solution to the problem of determining the parameters of motion of an orbiters center of mass is presented on the basis on the results of measurements carried out using the optical system of a space robot located in orbit coplanar to that of the orbiter. The space robot-orbiter line-of-sight angle and the line-of-sight rate in the moving orbital system of coordinates of the space robot are selected as initial parameters that are measured by the space robots on-board optical system. Along with the known orbital parameters of the space robot they are used to solve the problem of determining the parameters of motion of the orbiters center of mass. When solving this task, assumptions are introduced concerning the central gravitational field of the Earth, the coplanarity of the orbits of the space robot and of the orbiter, absence of influence of the atmosphere, the moon's attraction and the pressure of the solar wind on the motion of the space robot and of the orbiter, absence of errors in the results of measurements performed by the space robots on-board optics. Analytical expressions are obtained to determine the unknown parameters of motion of the orbiters center of mass. The results presented can be used to develop methods allowing standalone determination of parameters of the orbit of unknown orbiters using on-board optics of a space robot.
Method for determination of optimal geometrical parameters of a unit cell of X-shaped truss cores
Authors: Mousavi Safavi S. M.
Published: November 2019

Recently, in order to develop high-strength lightweight core materials of sandwich structures for multi-functional applications, a large number of truss structures have been created, including pyramidal and tetrahedral truss cores. In this paper, a new truss structure is developed to be used as core material in sandwich panels. The X-shaped truss core consists of discrete hourglass-shaped unit cells formed by the groove-to-groove connection of two flat X-shaped truss elements made by metal plate cutting. In order to determine optimal geometrical parameters of a unit cell of X-shaped truss core, in this work it is proposed to plot the diagrams of relative density versus the angle of the rods for the required values of equivalent critical compression and lateral shear stresses, and for the required values of equivalent compression and shear stiffness of the unit cell of X-shaped truss core. The results show that with the same mechanical characteristics, the relative density of the optimal X-shaped truss core is less than the relative density of optimal pyramidal and tetrahedral truss cores.

Attention Deficit Hyperactive Disorder is a common behavioural disorder that affects about 10% of school age children. About 7% children worldwide have Attention  Deficit Hyperactive Disorder. In rural India population, the prevalence of  Attention Deficit Hyperactive Disorder is 3.66%. The main aim of the study was to find out the effectiveness of self-instructional module on Attention Deficit Hyperactive Disorder. The investigators adopted a pre-experimental research design among seven selected schools through simple random sampling.A total of 80 primary school teachers were selected using the purposive sampling technique. Self-instructional module and structured knowledge questionnaire was prepared and sent  for validation. Pretesting and reliability was done and found reliable(r = 0.8). Firstly, pretest session was conducted using structured knowledge questionnaire to assess the knowledge of primary school teachers on Attention Deficit Hyperactive Disorder. Self- instructional module(SIM’s) was administered 4 days after the pretest session. After 14 days of SIM’s distribution, posttest was conducted to assess the effectiveness of self-instructional module. The findings reveal that majority 60% of primary school teachers have average knowledge in the pre-test and 86.25% had good knowledge in the post-test. The calculated paired ‘t’ test value ‘t = 11.259’ was found to be statistically significant at p<0.05 level. The study concluded that educational material in the form of self-instructional module helped the teachers to improve their knowledge on Attention Deficit Hyperactive Disorder. The gained in the knowledge from the Self-instructional module will help them to identify and manage children with Attention Deficit Hyperactive Disorder in future.
Environmental factors and life style having an impact on pathogenesis and etiology of Diabetes Mellitus

Type 2 diabetes mellitus (T2DM) is currently a public health problem worldwide and a threat to human health and social development. The incidence rate of the disease is steadily increasing. Various genetic and environmental factors have been established as influencing the pathogenesis of this disease. However, the influence of social factors and the natural environment on DM incidence should also be considered. Low-grade inflammation could represent a central point of connection integrating all these potential triggers, being partly responsible for the development of insulin resistance. This paper aims to elaborate on the impact of the natural environment and social factors on DM development, with a special focus on six aspects of the pathogenesis of DM: pollution, radiation, psychology, drink, sleep, and exercise. We identified a two-way relationship between T2DM and social and natural environments. Changes in these environments may lead to low-grade inflammation, which in turn induces or aggravates T2DM and vice versa. Poor lifestyle may lead to increased insulin resistance and promote DM development. Improvements in blood glucose control can be achieved through non-environmental and behavioral interventions.

Type 2 diabetes (T2DM) is a global epidemic and increases mortality due to its vascular complications. Chemerin has been found to exert a major role in glucose and lipid metabolism. The aim of this study was to explore the correlation between plasma Chemerin levels and microangiopathy in patients with T2DM. Methods. A total of 598 T2DM patients were classified into two groups: with and without micro vascular complications. Anthropometric parameters and blood pressure were taken. The amounts of glycosylated hemoglobin, glucose, lipid profiles, creatinine, and Chemerin concentrations in the blood were determined. The presence and severity of nephropathy, retinopathy, and neuropathy were also evaluated by specific tests. Results. Plasma levels of Chemerin in diabetic subjects with micro vascular complications were markedly elevated compared to those without. The number of micro vascular complications increased with high plasma Chemerin levels. Patients with high Chemerin levels had an increased incidence of nephropathy and retinopathy. Furthermore, the Chemerin plasma concentrations increased with the progression of diabetic nephropathy with highest values in macro albuminuria groups. In contrast, no significant difference was observed in plasma Chemerin levels between subjects with and without peripheral neuropathy. Pearson correlation analysis showed that plasma Chemerin levels were positively related to duration of diabetes, serum creatinine, and 24-hour urine albumin excretion, even after multiple adjustments. Using logistic regression analysis, plasma Chemerin concentrations were independently associated with the presence of nephropathy and retinopathy, not neuropathy. Conclusion. This study elucidated a positive correlation between increased Chemerin levels and the development of some subtypes of diabetic microangiopathy.
