ИССЛЕДОВАНИЕ И ПОЛУЧЕНИЕ СОРБЦИОННЫХ МАТЕРИАЛОВ НА ОСНОВЕ ТЕХНОЛОГИИ РЕЦИКЛИНГА ОТХОДОВ ТЕПЛОЭНЕРГЕТИЧЕСКОЙ ПРОМЫШЛЕННОСТИ (2018)

Основной задачей, направленной на снижение экологического воздействия сточных вод предприятий ТЭК, является разработка систем оборотного водопользования. Однако возвратные воды часто не могут быть использованы для питания парогенераторов даже после очистки, так как в лучшем случае происходит удаление из конденсата неэмульгированных нефтепродуктов, оксидов железа и катионов растворенных солей металлов. Но, как правило, эти возвращаемые с производств конденсаты содержат вещества, совершенно не задерживаемые ни катионированием, ни сорбцией, таким примером могут служить эмульгированные нефтепродукты, галогенопроизводные органические вещества. Если же и происходит незначительная сорбция этих веществ, то емкость таких материалов столь мала, что принимать ее во внимание не приходится. Сброс таких вод в дренаж вызовет лишь экономические потери, так как без тщательной очистки и предварительного охлаждения он запрещен. Важно, что обычными химическим и приборным контролем на ТЭС присутствие этих веществ не обнаруживается, так как они не меняют значения рН и электропроводности раствора. Такие соединения могут вызывать негативное воздействие на работу инженерных коммуникаций и теплосилового оборудования: в парогенераторах, подвергаясь гидролизу, они могут действовать как сильные кислоты, усиливать вспенивание и вызывать загрязнение пара, участвовать в формировании накипей [1].Цель: получить и исследовать сорбционные свойства загрузочного материала из отхода угледобычи. Модернизировать стандартную систему фильтрационного блока путем внедрения как новых конструкционных параметров фильтровальных установок, так и использования фильтрационных загрузок с высокими сорбционными показателями. Обосновать с точки зрения экологичесности и ресурсосбережения данного материала.Метод или методология проведения работы: при исследовании использовались стандартные методики оценки качества воды методы анализа сорбционных свойств материалов. Методы термографического анализа состава глиежа, методы математического моделирования и интерпретации результатов исследования.Результаты: получен сорбционный материал, исследованы оптимальные режимы активации сорбента, эффективность и селективность сорбции при различных температурах и pH.Область применения результатов: Результаты данного исследования могут быть применены в фильтрационных установках предприятий ТЭК с целью очистки сточной воды от нефтепрродуктов и тяжелых металлов.
Compressing video based on region of interest (2013)

Real-time video streaming suffer from bandwidth limitation that are unable to handle the high amount of video data. To reduce the amount of data to be streamed, we propose an adaptive technique to crop the important part of the video frames, and drop the part that are outside the important part; this part is called the Region of Interest (ROI). The Sum of Absolute Differences (SAD) is computed to the consecutive video frames on the server side to identify and extract the ROI. The ROI are extracted from the frames that are between reference frames based on three scenarios. The scenarios been designed to position the reference frames in the video frames sequence. Linear interpolation is performed from the reference frames to reconstruct the part that are outside the ROI on the mobile side. We evaluate the proposed approach for the three scenarios by looking at the size of the compressed videos and measure the quality of the videos by using the Mean Opinion Score (MOS). The results show that our technique significantly reduces the amount of data to be streamed over wireless networks with acceptable video quality are provided to the mobile viewers.

Visual programming using structured data flow (2002)

In the quest for a visual programming language that can be used effectively by a broad range of people with different programming skill levels, a system has been developed based on a dataflow model extended with graphical control-flow structures. This system eliminates many of the problems associated with using dataflow graphs as a programming language, making programs easier to construct while still preserving the natural understandability of dataflow diagrams. Subroutine-like modules are encapsulated using an icon-based notation that facilitates the construction of large programs through hierarchical composition. Finally, a compiler has been constructed that generates machine code that is comparable to code generated by compilers of conventional languages such as Pascal and C. The visual language, called G, is embedded in LabVIEW, a scientific software system for laboratory automation and simulation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Regularities in the spectrum of trebly ionized iodine (1936)

The spectrum of a condensed discharge through iodine has been photographed in the region λ 6000 to λ 1900 under varying conditions of excitation, and about 70 lines have been ascribed to trebly ionized iodine. Among these more than 30 lines have been classified; assignments for the levels have been suggested on the analogy of the other isoelectronic spectra, Te III, Sb II and Sn I.

Apoptotic mechanisms involved in neurodegenerative diseases:Experimental and therapeutic approaches (2008)

Alzheimer's disease (AD) and Parkinson's disease (PD) are two of the most significant neurodegenerative disorders in the developed world. However, although these diseases were described almost a century ago, the molecular mechanisms that lead to the neuronal cell death associated with these diseases are not yet clear, and vigorous research efforts have failed to identify effective treatment options. In the present review, we evaluate the potential mechanisms underlying apoptosis and neuronal death in neurodegenerative disorders. A role for mitochondria in the release of proapoptotic proteins, such as cytochrome c and apoptosis-inducing factor (AIF) etc., is discussed along with key processes involving oxidative stress and activation of glutamate receptors. We also deliberate the implication of DNA damage, primarily p53 induction and reentry in the cell cycle. Finally, we postulate that multitargeting therapies comprising antioxidants, cell cycle inhibitors and modulating agents of COX-2 or c-JUN kinase pathways could be suitable strategies to prevent or delay the process of neuronal cell death in neurodegenerative disorders. Thus, the aim of this review is to discuss the pathways involved in the pathogenesis of neurodegenerative diseases such as AD, PD and Huntington's disease (HD). Furthermore, current and future pharmacotherapeutics will be considered.
Optimization of Graphite Composite Latent Heat Storage Systems (2017)

The energy density and power density are critical properties of thermal energy storage systems. Use of a phase change material as the storage medium provides high energy density due to the ability to store energy as latent heat during the phase transition; however, the power density is limited by the low thermal conductivity. Insertion of a highly conductive graphite foam within the material can increase the rate of thermal response of the phase change material. As the graphite bulk density increases, the thermal conductivity increases, but the composite latent heat decreases due to displacement of the phase change material. This introduces a trade-off between energy density and power density of the composite. In this work, a validated numerical model is used to study the trade-off between energy density and power density with respect to graphite bulk density under various imposed heat fluxes. Comparisons are made based on the melting time, junction temperature between the composite and the heat source, and the volumetric energy density. To simplify the complicated relationship between composite thermophysical properties and charging response, two non-dimensional numbers are used. The Fourier number provides a comparison between the heat storage and heat diffusion by considering the thermal conductivity, latent heat, sensible heat, density, melting time, and volume. A dimensionless temperature compares the junction temperature (temperature between the heat source and the composite) when the sample is fully melted to the melt onset temperature. These non-dimensional numbers can assist in the design of latent heat storage systems where some parameters are fixed (such as heat flux, junction temperature, mass, operating time, or required energy storage) and others must be determined by the design (such as required thermal conductivity or height).
Dual-Plane Correlation for Three-Dimensional Particle Image Velocimetry on Planar Domains (1996)

Particle Image Velocimetry (PIV) is increasingly used to investigate unsteady flow velocity fields instantaneously. Thistechnique allows the recording of a complete velocity field in a plane of the flow within microseconds. In PIV the velocity vector field is usually determined by subdividing the recordings into small interrogation areas and employing particle tracking algorithms or statistical evaluation techniques. The method described in this paper is based onthe spatial cross-correlation of particle images stored on separate frames of each exposure. It is expanded by the analysis of the correlation peak heights. The correlation value depends on the portion of paired particle images, which itself depends on the out-of-plane velocity component, but also on other parameters such as background light, varying image size and number, loss of pairs dueto in-plane motion. To avoid problems arising from these other influences, images from a displaced light sheet plane,.
Risk factors for postcesarean surgical site infection (2000)

Host susceptibility and existing infections were important predictors of surgical site infection after cesarean delivery. Further intervention should target this high-risk group to reduce the clinical effect of surgical site infection.
CoolMPS: evaluation of antibody labeling based massively parallel non-coding RNA sequencing (2020)

Results of massive parallel sequencing-by-synthesis vary depending on the sequencing approach. CoolMPS™ is a new sequencing chemistry that incorporates bases by labeled antibodies. To evaluate the performance, we sequenced 240 human non-coding RNA samples (dementia patients and controls) with and without CoolMPS. The Q30 value as indicator of the per base sequencing quality increased from 91.8 to 94%. The higher quality was reached across the whole read length. Likewise, the percentage of reads mapping to the human genome increased from 84.9 to 86.2%. For both technologies, we computed similar distributions between different RNA classes (miRNA, piRNA, tRNA, snoRNA and yRNA) and within the classes. While standard sequencing-by-synthesis allowed to recover more annotated miRNAs, CoolMPS yielded more novel miRNAs. The correlation between the two methods was 0.97. Evaluating the diagnostic performance, we observed lower minimal P-values for CoolMPS (adjusted P-value of 0.0006 versus 0.0004) and larger effect sizes (Cohen's d of 0.878 versus 0.9). Validating 19 miRNAs resulted in a correlation of 0.852 between CoolMPS and reverse transcriptase-quantitative polymerase chain reaction. Comparison to data generated with Illumina technology confirmed a known shift in the overall RNA composition. With CoolMPS we evaluated a novel sequencing-by-synthesis technology showing high performance for the analysis of non-coding RNAs.
Efficient Linear Programming for Dense CRFs (2016)

The fully connected conditional random field (CRF) with Gaussian pairwise potentials has proven popular and effective for multi-class semantic segmentation. While the energy of a dense CRF can be minimized accurately using a linear programming (LP) relaxation, the state-of-the-art algorithm is too slow to be useful in practice. To alleviate this deficiency, we introduce an efficient LP minimization algorithm for dense CRFs. To this end, we develop a proximal minimization framework, where the dual of each proximal problem is optimized via block coordinate descent. We show that each block of variables can be efficiently optimized. Specifically, for one block, the problem decomposes into significantly smaller subproblems, each of which is defined over a single pixel. For the other block, the problem is optimized via conditional gradient descent. This has two advantages: 1) the conditional gradient can be computed in a time linear in the number of pixels and labels; and 2) the optimal step size can be computed analytically. Our experiments on standard datasets provide compelling evidence that our approach outperforms all existing baselines including the previous LP based approach for dense CRFs.

Broad AOX expression in a genetically tractable mouse model does not disturb normal physiology (2016)

Plants and many lower organisms, but not mammals, express alternative oxidases (AOXs) that branch the mitochondrial respiratory chain, transferring electrons directly from ubiquinol to oxygen without proton pumping. Thus, they maintain electron flow under conditions when the classical respiratory chain is impaired, limiting excess production of oxygen radicals and supporting redox and metabolic homeostasis. AOX from Ciona intestinalis has been used to study and mitigate mitochondrial impairments in mammalian cell lines, Drosophila disease models and, most recently, in the mouse, where multiple lentivector-AOX transgenes conferred substantial expression in specific tissues. Here, we describe a genetically tractable mouse model in which Ciona AOX has been targeted to the Rosa26 locus for ubiquitous expression. The AOX<sup>Rosa26</sup> mouse exhibited only subtle phenotypic effects on respiratory complex formation, oxygen consumption or the global metabolome, and showed an essentially normal physiology. AOX conferred robust resistance to inhibitors of the respiratory chain in organello; moreover, animals exposed to a systemically applied LD50 dose of cyanide did not succumb. The AOX<sup>Rosa26</sup> mouse is a useful tool to investigate respiratory control mechanisms and to decipher mitochondrial disease aetiology in vivo.
Effects of supplemental calcium and vitamin D on the APC/β‐catenin pathway in the normal colorectal mucosa of colorectal adenoma patients (2016)

APC/β-catenin pathway malfunction is a common and early event in colorectal carcinogenesis. To assess calcium and vitamin D effects on the APC/β-catenin pathway in the normal-appearing colorectal mucosa of sporadic colorectal adenoma patients, nested within a larger randomized, double-blind, placebo-controlled, partial 2 × 2 factorial chemoprevention clinical trial of supplemental calcium (1200 mg daily) and vitamin D (1000 IU daily), alone and in combination versus placebo, we assessed APC, β-catenin, and E-cadherin expression in colon crypts in normal-appearing rectal mucosa biopsies from 104 participants at baseline and 1-yr follow up using standardized, automated immunohistochemistry and quantitative image analysis. For vitamin D versus no vitamin D, the ratio of APC expression to β-catenin expression in the upper 40% (differentiation zone) of crypts (APC/β-catenin score) increased by 28% (P = 0.02), for calcium versus no calcium it increased by 1% (P = 0.88), and for vitamin D + calcium versus calcium by 35% (P = 0.01). Total E-cadherin expression increased by 7% (P = 0.35) for vitamin D versus no vitamin D, 8% (P = 0.31) for calcium versus no calcium, and 12% (P = 0.21) for vitamin D + calcium versus calcium. These results support (i) that vitamin D, alone or in combination with calcium, may modify APC, β-catenin, and E-cadherin expression in humans in directions hypothesized to reduce risk for colorectal neoplasms; (ii) vitamin D as a potential chemopreventive agent against colorectal neoplasms; and (iii) the potential of APC, β-catenin, and E-cadherin expression as treatable, pre-neoplastic risk biomarkers for colorectal neoplasms. © 2016 Wiley Periodicals, Inc.
Introduction to diffusion tensor imaging mathematics: Part I. Tensors, rotations, and eigenvectors (2006)

Abstract The mathematical aspects of diffusion tensor magnetic resonance imaging (DTMRI, or DTI), the measurement of the diffusion tensor by magnetic resonance imaging (MRI), are discussed in this three‐part series. In part I, some general features of diffusion imaging are presented briefly, including the relationship between the diffusion ellipsoid and the diffusion tensor. Rotations of vectors and tensors are explained for both two and three dimensions. Rotationally invariant properties of the diffusion tensor are discussed. Calculation of the eigenvectors and eigenvalues of the diffusion tensor, which correspond to the directions of the diffusion ellipsoid axes and the squares of the hemiaxis lengths, is explained. © 2006 Wiley Periodicals, Inc.

A Stable, Soluble, and Crystalline Supramolecular System with a Triplet Ground State (2017)

A supramolecular complex was constructed by encapsulation of a <sup>3</sup> O<sub>2</sub> molecule inside an open-cage C<sub>60</sub> derivative. Its single-crystal X-ray diffraction analysis revealed the presence of the <sup>3</sup> O<sub>2</sub> at the center of the fullerene cage. The CV measurements suggested that unprecedented dehydrogenation was promoted by the encapsulated <sup>3</sup> O<sub>2</sub> after two-electron reduction. The ESR measurements displayed the triplet character as well as the anisotropy of the <sup>3</sup> O<sub>2</sub> . Additionally, the SQUID measurements also demonstrated the paramagnetic behavior above 3 K without an antiferromagnetic transition. Upon photoirradiation with visible light, three phosphorescent bands at the NIR region were observed, arising from the exited <sup>1</sup> O<sub>2</sub> generated by self-sensitization with the outer cage, whose lifetimes were not affected by the environments. These studies confirmed that the complex is a crystalline triplet system with incompatible "high spin density" but "small interspin interaction" properties.
