Published: April 2019

In the age of information technology and the age of polymers, there are more and more tasks in scientific researches on chemistry and chemical technology. Such a phenomenon is explained by the fact that humanity develops very quickly. Consequently, the needs are enhancing dramatically, and therefore everyone objectively understands that natural resources decrease annually. The time will come when nature will not be enough for human existence. To plant a tree is not to build a house, but the construction of a wooden house requires more than one tree that grows over the years. In this paper, the authors try to prolong the life of various products and materials made of cheap wood species by using waste from production, which may partially ensure the preservation of nature. The article presents the results on the use of oligomer from petrochemical waste for the protective treatment of wood materials and high-density fiberboard (HDF). The dosage of secondary expanded polystyrene to oligomer from polybutadiene by-products varies from 10 to 40 %. The obtained samples of fiberboard, birch, linden and aspen are examined for resistance to water and moisture. The results indicate that the samples have high strength properties and resistance to water and moisture. Thus, the integrated use of waste and by-products allows them to be disposed and to be used for protective treatment of wood products, which contributes to improving the formability and service life of products.

Published: April 2019

Restorative processing of large-sized parts of rotating technological units, which include bandages and kiln rollers, is currently performed using embedded machine modules. At the same time, periodic processing is carried out during the operation of the unit without stopping. This processing requires special technical and technological approaches. This is due to the large dimensions of the parts and the inconstancy of the position of the axis of the rotating part, installed on two support rollers and having an error in shape in cross section. The technologies used are characterized by insufficient study of surface formation process during machining and arbitrarily set processing modes. An urgent task is to develop methods for finding rational modes in which the required accuracy and processing performance will be provided. A special place is occupied by the issues of processing modeling to find the optimal technological modes, taking into account the technical and physico-mechanical features of the process. The development of adequate mathematical models requires a deep analysis of the functional features of the equipment and technological features of the process. It is established that for optimization of processing modes it is necessary to enter a number of restrictions related to the tool, the driving feed, the rigidity of technological system, the quality of processing. In this case, the processing capacity is used as the target function; the depth and feed are used as varied parameters.

The urgency of the issue under study is due to dynamics of the number of children with disabilities in the country and in particular regions. For instance, the total number of disabled children in Russia receiving social pensions between the ages of 0 and 18 was more than 655 thousand, as of January 1, 2018. At the same time, an increase of this indicator is observed constantly. The need to develop scientifically based recommendations for the establishment of rehabilitation centers is due to the fact, that in most cases this assistance is provided in the adapted premises. It is not possible to carry out correctional work effectively. The article’s purpose is to identify factors in the formation of architectural environment of rehabilitation centers for children and adolescents with various disabilities. The systematic method of analyzing the objects in question is the leading approach to studying this problem. Identified factors are divided into external and internal. The external are natural, climatic and anthropogenic factors. Internal include functional and technological, medical and ergonomic, sanitary and hygienic, architectural and stylistic factors. All factors are interrelated. This is reflected in a pilot project of a rehabilitation center for children and adolescents in the Oryol Region. The materials of the article can be useful for architects when designing rehabilitation centers for children and adolescents with various disabilities.

Published: April 2019

Fibrous composites are progressive materials for buildings and structures. Structures based on them are characterized by high technical and economic characteristics. Glass fiber concrete is effective for thin-walled structures. Various principles of structural mechanics applied to fiber composites are pro-posed for solving design problems. The optimal configuration of the covering is determined by the sta-tionarity of its potential energy for given values of the calculated resistances of the material compo-nents. This formulation of the problem leads to a global minimum of the covering volume. In particu-lar, an axisymmetrically loaded spherical cover is considered; the optimal thickness is determined from the condition of equal resistance by the von Mises yield criterion. Types of elements for precast glass-fiber concrete of various spans are recommended. In addition, the shallow tunnels are consid-ered; they are a prevalent object of transport communications. The rationality of using the thin-walled spatial systems consisting of rectangular plates is established. The isoperimetric problem is solved for a given volume of material based on the generalized Lagrangian principles. The thickness of the rec-tangular plates of the spatial system of the tunnel is taken as a variable parameter.

High Blood miR-802 Is Associated With Poor Prognosis in HCC Patients by Regulating DNA Damage Response 1 (REDD1)-Mediated Function of T Cells
Authors: Jiang Chao , Liu Xueyan , Wang Meng , Lv Guoyue , Wang Guangyi
Published: April 2019

miR-802 has been reported to be dysregulated in multiple tumors and contribute to tumor progression. However, its role in HCC was still largely unknown. The aim of this study is to investigate the function and mechanism of miR-802 in HCC progression. The results showed that miR-802
was upregulated in the peripheral blood and tumor tissue of HCC patients, and high levels of blood miR-802 predicted poor prognosis. miR-802 had no effect on the proliferation and migration of HCC cell lines. Interestingly, the levels of CD8/CD28 and regulated in development and DNA damage
response 1 (REDD1) were declined along with the upregulation of miR-802 in vivo. Hence, it is speculated that miR-802 participated in the regulation of T-cell function in HCC patients. Furthermore, we demonstrated that mir-802 directly targets REDD1 and inhibited its expression. miR-802 increased
the expression of programmed cell death protein 1 (PD-1) and decreased the expression of interferon-γ (IFN-γ) and CD8+CD28+ T-cell number. In conclusion, miR-802 was involved in T-cell exhaustion through posttranscriptionally suppressing REDD1, which might
offer the suppressive effect of miR-802 on HCC progression.

Published: April 2019

A room-temperature high-performance ammonia (NH3) gas sensor based on hydroxyapatite (HAp) film with three-dimensional network structure was reported in this paper. The gas sensor was fabricated on the indium tin oxide glass (ITO) interdigital electrode via simple electrochemical deposition technique. The HAp film gas sensor shows good sensitivity, high reproducibility and excellent selectivity to NH3 gas under dry and relative humidity (RH) conditions at room temperature. The response and recovery time of the HAp film gas sensor to 1000 ppm NH3 gas are 23 s and 14 s under N2 (dry) condition, and are 4 s and 11 s under air (RH≈30) condition, respectively. The HAp film gas sensor has no considerable deviation in the 1000 ppm NH3 gas for 3 cycles under N2 (dry), and so is air (RH≈30) conditions. The HAp film gas sensor shows excellent selectivity to methanol, acetone and ethanol under N2 (dry) and air (RH≈30) conditions. Above all, two sensing mechanisms of the HAp film gas sensor to NH3 gas have been also researched in this work.

EFFECTIVE FINITE-DIFFERENCE METHODS FOR THE SOLUTIONS OF FILTRATION PROBLEMS IN MULTILAYER DOMAINS
Authors: Kalis H.
Published: April 2019

In papers [1,2] there were consider different assumptions for averaging methods along the vertical coordinate.These methods were applied for the mathematical simulation of the mass transfer process in multilayered underground systems. A specific feature of these problems is that it is necessity to solve the 3‐D initial‐boundary‐value problems for parabolic type partial differential equations of second order with piece‐wise parameters in multilayer domain.Therefore here an effective finite‐difference method for solving a problem of the above type is developed.This method may be considered as a generalization of the method of finite volumes [3] for the layered systems. In the case of constant piece‐wise coefficients we obtain the exact discrete approximation of steady‐state 1‐D boundary‐value problem.This procedure allows to reduce the 3-D problem to a system of 2-D problems and the 2-D problem to a system of 1-D problems.

Published: April 2019

Metabolic P (MP) systems are a part of the infobiotics research field. The intravenous glucose tolerance test (IVGTT) MP system models glucose-insulin interactions. MP system implementation in software is well researched, although there is a lack of techniques for hardware implementation, specifically with field programmable gate arrays. In this article the existing techniques are examined first, including combinative, single digital signal processor element, and pipelined. Then the specifics of six different IVGTT MP systems are analyzed. Having in mind these specifics, a new unified combinative IVGTT MP system implementation in field programmable gate arrays is proposed.

Published: April 2019

As protostars evolve from optically faint/infrared-bright (Class I) sources to optically bright/infrared-faint (Class II) the solid material in their surrounding disks accumulates into planetesimals and protoplanets. The nearby, young Ophiuchus star-forming region contains hundreds of protostars in a range of evolutionary states. Using the Atacama Large Millimeter Array to observe their millimeter continuum emission, we have measured masses of, or placed strong upper limits on, the dust content of 279 disks. The masses follow a log-normal distribution with a clear trend of decreasing mass from less to more evolved protostellar infrared class. The (logarithmic) mean Class I disk mass, M = 3.8 M
⊕, is about 5 times greater than the mean Class II disk mass, but the dispersion in each class is so high, σ
logM
 ≃ 0.8–1, that there is a large overlap between the two distributions. The disk mass distribution of flat-spectrum protostars lies in between Classes I and II. In addition, three Class III sources with little to no infrared excess are detected with low disk masses, M ≃ 0.3 M
⊕. Despite the clear trend of decreasing disk mass with protostellar evolutionary state in this region, a comparison with surveys of Class II disks in other regions shows that masses do not decrease monotonically with age. This suggests that the cloud-scale environment may determine the initial disk mass scale or that there is substantial dust regeneration after 1 Myr.
The First Constraint from SDSS Galaxy–Galaxy Weak Lensing Measurements on Interacting Dark Energy Models
Authors: Zhang Jiajun , An Rui , Luo Wentao , Li Zhaozhou , Liao Shihong , Wang Bin
Published: April 2019

We combine constraints from linear and nonlinear scales, for the first time, to study the interaction between dark matter (DM) and dark energy (DE). We devise a novel N-body simulation pipeline for cosmological models beyond ΛCDM. This pipeline is fully self-consistent and opens a new window to study the nonlinear structure formation in general phenomenological interacting DE models. By comparing our simulation results with the SDSS galaxy–galaxy weak lensing measurements, we are able to constrain the strength of interaction between DE and DM. Compared with the previous studies using linear examinations, we point to plausible improvements on the constraints of interaction strength by using small-scale information from weak lensing. This improvement is mostly due to the sensitivity of weak lensing measurements on nonlinear structure formation at low redshift. With this new pipeline, it is possible to look for smoking gun signatures of DM–DE interaction.

Published: April 2019

Objective.

We investigated the association of age and anticyclic citrullinated peptide antibodies (anti-CCP) in subjects without rheumatoid arthritis (RA).

Methods.

Serum was tested for anti-CCP3.1 (IgG/IgA) in 678 first-degree relatives (FDR) of patients with RA and 330 patients with osteoarthritis (OA). Individual isotypes (anti–CCP-IgA and anti–CCP-IgG) were also tested in all FDR.

Results.

In FDR, increasing age was significantly associated with positivity for anti-CCP3.1 (per year, OR 1.03) and anti–CCP-IgA (per year, OR 1.05) but not anti–CCP-IgG. In FDR and OA subjects, anti-CCP3.1 prevalence was significantly increased after age 50 years.

Conclusion.

Increasing age in individuals without RA should be considered in the interpretation of anti-CCP3.1 positivity.
Patient Preferences for Disease-modifying Antirheumatic Drug Treatment in Rheumatoid Arthritis: A Systematic Review
Authors: Durand Caylib , Eldoma Maysoon , Marshall Deborah A. , Bansback Nick , Hazlewood Glen S.
Published: April 2019

Objective.

To summarize patients’ preferences for disease-modifying antirheumatic drug (DMARD) therapy in rheumatoid arthritis (RA).

Methods.

We conducted a systematic review to identify English-language studies of adult patients with RA that measured patients’ preferences for DMARD or health states and treatment outcomes relevant to DMARD decisions. Study quality was assessed using a published quality assessment tool. Data on the importance of treatment attributes and associations with patient characteristics were summarized across studies.

Results.

From 7951 abstracts, we included 36 studies from a variety of countries. Most studies were in patients with established RA and were rated as medium- (n = 19) or high-quality (n = 12). The methods to elicit preferences varied, with the most common being discrete choice experiment (DCE; n = 13). Despite the heterogeneity of attributes in DCE studies, treatment benefits (disease improvement) were usually more important than both non-serious (6 of 8 studies) and serious adverse events (5 of 8), and route of administration (7 of 9). Among the non-DCE studies, some found that patients placed high importance on treatment benefits, while others (in patients with established RA) found that patients were quite risk averse. Subcutaneous therapy was often but not always preferred over intravenous therapy. Patient preferences were variable and commonly associated with the sociodemographic characteristics.

Conclusion.

Overall, the results showed that many patients place a high value on treatment benefits over other treatment attributes, including serious or minor side effects, cost, or route of administration. The variability in patient preferences highlights the need to individualize treatment choices in RA.
Evidence-Based Practice Guideline: Assessing Heart Failure in Long-Term Care Facilities
Authors: Harrington Candace C.
Published: April 2019

Evidence suggests the most crucial elements to successful heart failure (HF) management in long-term care (LTC) include improving staffs' HF knowledge to recognize and intervene in early symptom exacerbations, embedding an effective and integrated interprofessional communication system into daily care processes, risk stratification, and anticipatory advanced care planning. Despite a large body of evidence describing best practices, quality HF management remains elusive in LTC facilities. Studies have shown that care quality and outcomes improve when the entire team, including direct caregivers, have an active role in residents' care planning and implementation. The current article summarizes a revised evidence-based practice guideline on assessing HF, addressing a systematic approach to care delivery, and implementing evidence-based best practices for HF quality improvement initiatives in LTC, post-acute care, and short-term rehabilitation settings.

Review of Cystic Fibrosis
Authors: Goetz Danielle , Ren Clement L.
Published: April 2019

Cystic fibrosis (CF) is an autosomal recessive disease characterized by pancreatic insufficiency and chronic endobronchial airway infection. This latter feature results in progressive bronchiectasis and ultimately respiratory failure, which is the leading cause of death in patients with CF. Other complications include sinusitis, diabetes mellitus, bowel obstruction, hepatobiliary disease, hyponatremic dehydration, and infertility. Diagnosis of CF is confirmed by demonstration of elevated sweat chloride. Most cases of CF are identified through newborn screening (NBS). There are also infants with positive NBS but inconclusive diagnostic testing; a small proportion of these infants may go on to develop CF. CF is a lifelong, life-limiting disease, but an organized care center network with multidisciplinary approach, quality improvement initiatives, and research has led to markedly increased survival and development of adult CF care programs. In the past few years, medications that directly target the underlying CF defect have been developed, which should result in even greater survival benefits.

An Empirical Study on Factors related to Distributed Pair Programming
Authors: Tsompanoudi Despina , Satratzemi Maya , Xinogalos Stelios , Karamitopoulos Leonidas
Published: April 2019

This paper reports students’ perceptions and experiences attending an object-oriented programming course in which they developed software using the Distributed Pair Programming (DPP) technique. Pair programming (PP) is typically performed on one computer, involving two programmers working collaboratively on the same code or algorithm. DPP on the other hand is performed remotely allowing programmers to collaborate from separate locations. PP started in the software industry as a powerful way to train programmers and to improve software quality. Research has shown that PP (and DPP) is also a successful approach to teach programming in academic programming courses. The main focus of PP and DPP research was PP’s effectiveness with respect to student performance and code quality, the investigation of best team formation strategies and studies of students’ attitudes. There are still limited studies concerning relationships between performance, attitudes and other critical factors. We have selected some of the most common factors which can be found in the literature: academic performance, programming experience, student confidence, feelgood factor, partner compatibility and implementation time. The main goal of this study was to investigate correlations between these attributes, while DPP was used as the main programming technique.
Social Media and Student With Disabilities
Authors: Doran Caoimhe , Schnackenberg Heidi Lee
Published: April 2019

In the past decade, social media has become an increasingly prevalent, being the daily form of communication and entertainment for a majority of individuals. Social media and networking sites are not designed to appeal to a specific type of personality and are designed to benefit many. The students of Generation Z respond positively to teaching styles that incorporate technology-based learning, and frequent communication or feedback. Gen Z students with disabilities are entitled to the same opportunities and experiences as their peers without disabilities. This includes being exposed to various forms of social media to discover alternative ways to communicate, interact with the community, find information and access entertainment. While other members of Generation Z possess the capability to pick up a smart phone or computer, create a social media account and figure out the functions independently, students with disabilities may require explicit instruction, strategies and practice with social media usage.
Minority College Students and Digital Agency
Authors: Baker Charlotte , Blankenship Rebecca J.
Published: April 2019

As noted in the 2017 Horizon Report on Higher Education, it is no longer enough to simply graduate with a degree in a particular discipline; the Hart Research Associates Report also emphasizes the point that employers are requesting that colleges and universities place more emphasis on practical and real-world skills rather than focusing on competencies in broader disciplinary theories that may never be applied practically in the daily workplace setting. In this chapter, the authors look at two specific examples: preservice teacher training and the training of graduate students in epidemiology (STEM). The purpose of this qualitative analysis is to examine and compare the literature related to two primary concepts: (1) access to technology and digital literacy of minority college students and (2) minority serving institution (MSI) response to promoting digital literacy among faculty and students enrolled in clinically based programs.

Published: April 2019

Currently, Chinese commercial banks are facing extremely tremendous pressure, including financial disintermediation, interest rate marketization, and internet finance. Meanwhile, increasing financial consumption demand of customers further intensifies the competition among commercial banks. Hence, it is very important to store, process, manage, and analyze the data to extract knowledge from the customer to predict their investment direction in future. Customer retention and fraud detection are the main information for the bank to predict customer behavior. It may involve the privacy data and sensitive data of the customer. Data security and data protection for the machine learning prediction is necessary before data collection. The research is focused on two parts: the first part is data security of machine learning and second part is machine learning prediction. The result is to prove the data security for the machine learning is important. Using different machining learning analysis tool to enhance the performance and reliability of machine learning applications, the customer behavior prediction accuracy can be enhanced.

Published: April 2019

Computers generate a large volume of logs recording various events of interest. These logs are a rich source of information and can be analyzed to extract various insights about the system. However, due to its overwhelmingly large volume, logs are often mismanaged and not utilized effectively. The goal of this chapter is to help researchers and industrial professionals make more informed decisions about their logging solutions. It first lays the foundation by describing log sources and format. Then it describes all the components involved in logging. The remainder of the chapter provides a survey of different log analysis techniques and their applications, consisting of conventional techniques using rules and event correlators that can detect known issues, plus more advanced techniques such as statistical, machine learning, and deep learning techniques that can also detect unknown issues. The chapter concludes describing the underlying concepts of the techniques, their application to log analysis, and their comparative effectiveness.

Authors: Miloud Mihoubi , Abdellatif Rahmoun , Lorenz Pascal
Published: April 2019

WSNs have recently been extensively investigated due to their numerous applications where processes have to be spread over a large area. One of the important challenges in WSNs is secure node localization. Its main objective is to protect the circulated information in WSN for any attack with low energy. For this reason, recent approaches relying on swarm intelligence techniques are called and the node localization is seen as an optimization problem in a multi-dimensional space. In this chapter, the authors present an improvement to the original bat algorithm for information protecting during the localization task. Hence, the proposed approach computes iteratively the position of the nodes and studied the scalability of the algorithm on a large WSN with hundreds of sensors that shows pretty good performance. Moreover, the parameters are simulated in different scenarios of simulation. In addition, a comparative study is conducted to give more performance to the proposed algorithm.
