The Influence of Cross Section Shape on Strengthening of Hollow Core Slabs
Authors: Vasilyev A.S. , Bazhenov Ruslan I. , Gorbunova Tatiana N.
Published: September 2018

Increasing pressure in separate areas when reconstructing and improving industrial buildings, may necessarily mean strengthening structural surfaces of buildings. In experimental and analytical assessment hollow cores slabs are represented as T-beams and I-beams. The width of the beam edge decreases according to the dimensions of the voids inside the slab. In this paper the authors test bearing strength and deformability of hollow core slabs in different conditions of strengthening. Furthermore, the scholars perform their calculations in a non-linear system, with a progressive loading, until the samples are destroyed, with a plastic hinge formed in the area extended in a slab cross section. Simulation and figure analyses were designed in ANSYS program. The researchers’ resulting of the stress-strain state of hollow core slabs is observed experimentally at various stages of loading. The researchers compared calculations of slabs with the full-scale cross section shape and calculations of the same I-beam slabs. Though, the investigators dwell on the impact of the cross-section on the results of the maximum slab deflections. The paper is also dedicated to a variety of strengthening modes and it explains that the cracking point for full-scale slabs comes after.

Published: September 2018

Ensuring effective operation of structures in zones of aggressive media is associated with the task of studying, obtaining and developing composites of increased chemical resistance, strength and crack resistance. Structures based on corrosion-resistant materials (particularly polymer concretes) play a large role in solving these problems. One of these polymer concretes is rubber concrete or abbreviated as rubcon. This article is devoted to the study of the resistance of the external load to rubber concrete beams of a T-section. As a result of the experiments carried out on three series of rubber concrete T-beams with a different amount of longitudinal reinforcement, quantitative characteristics of the strength and crack resistance of their normal sections were obtained.

Authors: Khezhev Tolya , Zhurtov Artur , Hadzhishalapov Gadzhimagomed H.
Published: September 2018

The results of research on the development of heat-resistant cement composites using volcanic pumice and expanded vermiculite are presented. Compositions of heat-resistant cement composites are proposed that significantly reduce Portland cement consumption and simultaneously improve their heat-resistant properties. The use of basalt fibers in composites makes it possible to increase their strength, crack resistance and heat-resistant properties due to the perception of tensile temperature stresses. Part of the expensive vermiculite can be replaced by pumice without significantly increasing the average density of the composite, while their strength characteristics increase.
Multi-Purpose Porous Ceramic Material
Authors: Bagaiskov Yu.S.
Published: September 2018

The main criteria for evaluation of ceramic products’ properties are strength, structural and mechanical, and thermophysical properties. To produce ceramic composites with a wide range of structural, mechanical, strength, and performance properties depending on application, various additives (flux agents, sintering agents, fillers) and heat treatment processes are used. Studies to determine a rational mixture composition have been carried out. A multipurpose material, comprising particles of the basic chamotte filler (burned clay) with a bonding agent in the form of refractory clay from the Latnenskoye deposit with a field spar fluxing agent, an additional filler made of heat-resistant silicon carbide, and an adhesive component in the form of powdered dextrin, is suggested. According to the combination of its ensured parameters, the obtained ceramic material can be multipurpose. Its degree of porosity and permeability make the material filtering, sound-proofing, and heat-retaining; considering the low density, it can be used as a lightweight construction material.

Authors: Kulterbaev Khusen P. , Baragunova Lyalusya A. , Shogenova Maryana M.
Published: September 2018

Stationary longitudinal vibrations of the vertical rod, kinematically excited by deterministic and random processes, are considered. In a joint examination, these tasks have many similarities. An additional reason for considering both problems was that the results obtained in the deterministic problem can be used to study the problem in stochastic formulation. In solving specific examples, analytical and numerical methods of solution are used. The amplitudes and variances of the oscillations are found. Numerical examples show the effect of broadband input random processes on the dispersion of oscillations. It is pointed out that it is necessary to expand the subject of studying random oscillations taking into account the results obtained.

Authors: Frolova I.I. , Andreev Vladimir I.
Published: September 2018

The paper contains comparative analysis of solutions for problems with the rock-mass stress-strain state in the vicinity of a spherical cavity for the case of stationary and non-stationary temperature conditions. Such a cavity was created by blasting and further was used as storage for products that tend to self-heating. So, both problems considered the process inhomogeneity of the rock mass soil and the inhomogeneity caused by an action of various high-temperature fields. The results obtained prove the significant impact of the inhomogeneity on the stress state of the rock mass for any types of temperature conditions. The development of methods for calculation of underground structures that would fully consider the conditions of their creation and operation as well as actual properties of materials is one of crucial areas in structural mechanics.

Development of Heating and Cooling Local Air Conditioning System for Houses
Authors: Melikyan Zohrab , Egnatosyan Naira , Egnatosyan Siranush
Published: September 2018

Centralized air conditioning systems are widely used in buildings at present. In these conditioners, the outside air gets required temperature, humidity, purity, and other features, necessary for creating comfort microclimate in inside areas of houses, and by the help of fans and air ducts the processed air moves to all rooms of a building. As a result, the creation and maintenance of comfort conditions in buildings become complicated and expensive activity. From this point of view, it is becoming more expedient to install local air conditioners in each room instead of single central one for the whole building. For this reason new local air conditioner is developed.

The combined inhibition of histone deacetylases (HDAC) and the proteins of the bromodomain and extraterminal (BET) family have recently shown therapeutic efficacy against melanoma, pancreatic ductal adenocarcinoma, testicular, and lymphoma cancers in murine studies. However, in such studies, the role of the immune system in therapeutically controlling these cancers has not been explored. We sought to investigate the effect of the HDAC inhibitor romidepsin (RMD) and the BET inhibitor IBET151, both singly and in combination, on vaccine-elicited immune responses. C57BL/6 mice were immunized with differing vaccine systems (adenoviral, protein) in prime-boost regimens under treatment with RMD, IBET151, or RMD+IBET151. The combined administration of RMD+IBET151 during vaccination resulted in a significant increase in the frequency and number of Ag-specific CD8+ T cells. RMD+IBET151 treatment significantly increased the frequency of vaccine-elicited IFN-γ+ splenic CD8+ T cells and conferred superior therapeutic and prophylactic protection against B16-OVA melanoma. RNA sequencing analyses revealed strong transcriptional similarity between RMD+IBET151 and untreated Ag-specific CD8+ T cells except in apoptosis and IL-6 signaling–related genes that were differentially expressed. Serum IL-6 was significantly increased in vivo following RMD+IBET151 treatment, with recombinant IL-6 administration replicating the effect of RMD+IBET151 treatment on vaccine-elicited CD8+ T cell responses. IL-6 sufficiency for protection was not assessed. Combined HDAC and BET inhibition resulted in greater vaccine-elicited CD8+ T cell responses and enhanced therapeutic and prophylactic protection against B16-OVA melanoma. Increased IL-6 production and the differential expression of pro- and anti-apoptotic genes following RMD+IBET151 treatment are likely contributors to the enhanced cancer vaccine responses.

Dasatinib is currently approved for clinical use as a first-line treatment agent for newly diagnosed chronic myeloid leukemia (CML). However, only a few clinical trials have been performed to evaluate dasatinibinduced PE following first-line therapy. We investigated the incidence and clinical features of dasatinib-induced PE following first-line therapy in Japanese CML patients of real world clinical practice settings. Among 22 patients, the median age of PEpositive patients was higher than that of PEnegative patients. Major molecular response was achieved in 75% of PE-positive patients and 50% of PE-negative patients. Most patients developed PE more than 1 year after treatment. Appearance of PE is associated with better clinical response during dasatinib treatment, however it is developed at any time. Elderly and high-risk patients tend to develop PE. The clinical features of dasatinib-induced PE following first-line therapy might be late onset and might not immediately follow the increasing of large granular lymphocyte.

Published: September 2018

Sezary syndrome (SS) is a leukemic form of cutaneous T-cell lymphoma and is chemo-resistant. Allogeneic hematopoietic stem cell transplantation is a promising therapy for SS; however, relapse is common. Therapeutic options after relapse have not been established. We managed an SS patient with hematological relapse within one month after transplantation. After discontinuation of immunosuppressants, she achieved complete remission and remained relapse-free. The chimeric analyses of Tcells showed that the full recipient type became complete donor chimera after immunological symptoms. This clinical course suggested that discontinuation of immunosuppressants may result in a graftversus- tumor effect, leading to the eradication of lymphoma cells.

This study aims to find the cut-off value and diagnostic accuracy of the use of RDW as initial investigation in enabling the differentiation between IDA and NTDT patients. Patients with microcytic anemia were enrolled in the training set and used to plot a receiving operating characteristics (ROC) curve to obtain the cut-off value of RDW. A second set of patients were included in the validation set and used to analyze the diagnostic accuracy. We recruited 94 IDA and 64 NTDT patients into the training set. The area under the curve of the ROC in the training set was 0.803. The best cut-off value of RDW in the diagnosis of NTDT was 21.0% with a sensitivity and specificity of 81.3% and 55.3% respectively. In the validation set, there were 34 IDA and 58 NTDT patients using the cut-off value of >21.0% to validate. The sensitivity, specificity, positive predictive value and negative predictive value were 84.5%, 70.6%, 83.1% and 72.7% respectively. We can therefore conclude that RDW >21.0% is useful in differentiating between IDA and NTDT patients with high diagnostic accuracy

Thrombopoietin (TPO) is a critical regulator of hematopoiesis. We previously reported that a severe aplastic anemia (SAA) who received a short-term administration of pegylated recombinant human megakaryocyte growth and development factor (rHuMGDF). A trilineage hematologic response was induced, however the patient was diagnosed with leukemia after nine years and eight months from administration of rHuMGDF. In recent reports, somatic mutations in myeloid cancer candidate genes were present in one-third of the AA. A mutant clone may be expanded by rHuMGDF in our patient. The long-term safety of patients treated with TPO and eltrombopag remains unknown. Careful observations are warranted hereafter.

Published: September 2018

En este trabajo se presenta el diseño de un sistema de control difuso PD+I embebido aplicado en el control de voltaje de un convertidor electrónico de potencia bidireccional multi-fase CD-CD. El controlador difuso cuenta con dos entradas, la primera se le denomina Error y es la diferencia entre el valor de voltaje deseado en la salida del convertidor y el voltaje medido en la salida del mismo; la segunda entrada es definida por las variaciones en el voltaje medido. La salida del controlador difuso define las variaciones en el ciclo de trabajo de los interruptores de potencia que controlan el convertidor. El sistema de control difuso se embebió en la tarjeta de desarrollo NI myRIO-1900 utilizando como software de programación LabVIEW, empleando el sistema embebido para realizar pruebas experimentales con el prototipo del convertidor. Con este sistema de control de voltaje se logra estabilizar el convertidor en los modos de operación reductor y elevador, demostrando un adecuado comportamiento del convertidor en el arranque y ante cambios de carga resistiva, manteniendo tiempos aceptables para aplicaciones futuras en micro-redes de CD conectando el bus de CD con un banco de super-capacitores o un banco de baterías.

Authors: Fernández C. , Pantano N. , Godoy S. , Serrano E. , Scaglia G.
Published: September 2018

En este trabajo se propone una estrategia de control en lazo cerrado para el seguimiento de perfiles óptimos previamente definidos para un bioproceso fed-batch. La mayor ventaja de este enfoque es que las acciones de control se calculan resolviendo un sistema de ecuaciones lineales, sin tener que linealizar el modelo matemático, lo que permite trabajar en cualquier rango. Además, se plantean tres técnicas para la sintonización de los parámetros del controlador diseñado. Primero se propone un método de Monte Carlo, el cual es un método probabilístico. En segundo lugar, se presenta una metodología basada en Algoritmos Genéticos, una técnica evolutiva de optimización. La tercera alternativa es el desarrollo de un Algoritmo Híbrido, diseñado a partir de la combinación de los dos métodos anteriores. En todos los casos, el objetivo es encontrar los parámetros del controlador que minimicen el error total de seguimiento de trayectorias. El desempeño del controlador se evalúa a través de simulaciones en condiciones normales de operación y frente a incertidumbre paramétrica, empleando los parámetros del controlador obtenidos.

El uso de interfaces cerebro-máquina en personas que han sufrido un accidente cerebro-vascular puede ayudar en su proceso de rehabilitación mediante la implicación cognitiva del paciente. Dichas interfaces traducen las ondas cerebrales en comandos con el fin de controlar un dispositivo mecánico de movimiento asistido. No obstante, el control de estos dispositivos debería ser más robusto y tener una alta precisión. Este trabajo estudia si algoritmos basados en transformadas como las de Stockwell o Hilbert-Huang pueden mejorar el control de estos dispositivos aumentando su precisión, y si es recomendable llevar a cabo una personalización por sujeto y configuración de electrodos. Mediante el análisis de cinco voluntarios se comprueba además, que no es posible detectar con suficiente robustez la intención motora a partir de la desincronización/sincronización relacionada a eventos motores con únicamente los datos previos al movimiento. Por ello, es preciso extender el tiempo de análisis a los dos segundos posteriores al inicio del movimiento.
Introduction
Authors: Zogry Kenneth Joel
Published: September 2018

The introduction explains the role of the Daily Tar Heel, the UNC student newspaper, in the broader context of the university and the state of North Carolina. It outlines the key arguments and themes in the book: academic freedom, freedom of speech and press; the ideological evolution of the university; the political push-pull over progressivism and conservatism in the state; and the role of big-time athletics at a top-tier research institution.
A Free Press Must Prevail
Authors: Zogry Kenneth Joel
Published: September 2018

This chapter covers the growth, development, and challenges facing UNC in the last decades of the 20th century, and the pressures on the student newspaper, both financially and ideologically. The Daily Tar Heel came under constant fire for being too politically left, or liberal, even though there were some more conservative editors and columnists. Attempts were made to defund the paper, and/or shut it down, including two lawsuits. The growing conservatism of the student body is covered, along with the rise of the New Right nationally. The Black Student Movement, the Women’s Movement, and the Gay and Lesbian Rights Movement (later LGBTQ) are topics debated heavily on campus and in the student newspaper. Importance of basketball is discussed, as the UNC tem becomes a national power. As the paper turns 100 years old, a plan is developed to again take it off-campus as a private non-profit organization.
Cuban Revolution in America
Authors: Latner Teishan A.
Published: September 2018

Cuba’s grassroots revolution prevailed on America's doorstep in 1959, fueling intense interest within the multiracial American Left even as it provoked a backlash from the U.S. political establishment. In this groundbreaking book, historian Teishan A. Latner contends that in the era of decolonization, the Vietnam War, and Black Power, socialist Cuba claimed center stage for a generation of Americans who looked to the insurgent Third World for inspiration and political theory. As Americans studied the island’s achievements in education, health care, and economic redistribution, Cubans in turn looked to U.S. leftists as collaborators in the global battle against inequality and allies in the nation’s Cold War struggle with Washington. By forging ties with organizations such as the Venceremos Brigade, the Black Panther Party, and the Cuban American students of the Antonio Maceo Brigade, and by providing political asylum to activists such as Assata Shakur, Cuba became a durable global influence on the U.S. Left. Drawing from extensive archival and oral history research and declassified FBI and CIA documents, this is the first multidecade examination of the encounter between the Cuban Revolution and the U.S. Left after 1959. By analyzing Cuba’s multifaceted impact on American radicalism, Latner contributes to a growing body of scholarship that has globalized the study of U.S. social justice movements.
Revolution in the Air
Authors: Latner Teishan A.
Published: September 2018

Chapter Three explores Cuba’s image within the U.S. radical imaginary through the surge of airplane hijackings that occurred from the U.S. to Cuba between 1968 and 1973. Seeking political asylum, sanctuary from criminal charges, contact with Third World revolutionary movements, and apolitical adventure, Americans who hijacked airplanes to Cuba often framed air piracy as an act of political protest. Cuban immigration officials were not always convinced, however, viewing many hijackers as criminals, not revolutionaries. Making ninety attempts to reach Cuba in commandeered aircraft, American air pirates ultimately forced the U.S. and Cuban governments into unprecedented high-level negotiations despite the nations’ lack of diplomatic relations. Viewing hijacking as a liability, the Cuban government moved to counter its outlaw mystique in the American popular imagination, with the two governments signing a bilateral agreement to curb hijacking in 1973.

From his enslavement to freedom, Frederick Douglass was one of America's most extraordinary champions of liberty and equality. Throughout his long life, Douglass was also a man of profound religious conviction. In this concise and original biography, D. H. Dilbeck offers a provocative interpretation of Douglass's life through the lens of his faith. In an era when the role of religion in public life is as contentious as ever, Dilbeck provides essential new perspective on Douglass's place in American history. Douglass came to faith as a teenager among African American Methodists in Baltimore. For the rest of his life, he adhered to a distinctly prophetic Christianity. Imitating the ancient Hebrew prophets and Jesus Christ, Douglass boldly condemned evil and oppression, especially when committed by the powerful. Dilbeck shows how Douglass's prophetic Christianity provided purpose and unity to his wide-ranging work as an author, editor, orator, and reformer. As "America's Prophet," Douglass exposed his nation’s moral failures and hypocrisies in the hopes of creating a more just society. He admonished his fellow Americans to truly abide by the political and religious ideals they professed to hold most dear. Two hundred years after his birth, Douglass's prophetic voice remains as timely as ever.

Introduction
Authors: Coley Jonathan S.
Published: September 2018

This introductory chapter reviews the central problem facing past theories of activist group participation: the assumption that all activists share the same motivations for joining and committing to activist groups and that all activists follow the same biographical pathways after participating in activist groups. The chapter illustrates this problem through a vignette of three activists mobilizing for LGBT equality at their Christian colleges and universities, one who fits the traditional portrait of a highly politicized activist, but two others who come from relatively conservative or apolitical backgrounds and contradict most assumptions about activists. After outlining the book’s intervention into the literature on activist group participation, the chapter then addresses the question of why readers should care about issues facing LGBT students at Christian colleges and universities, even though the federal government currently allows Christian colleges and universities to discriminate against LGBT people and even though LGBT people could theoretically choose to attend other schools. The chapter concludes with a brief discussion of the qualitative, in-depth interview data on 65 students at the book’s four primary sites, specifically, Belmont University, the Catholic University of America, Goshen College, and Loyola University Chicago.
The Context of Change
Authors: Coley Jonathan S.
Published: September 2018

This chapter addresses the question of how something that seemed unthinkable even in the early 2000s – LGBT inclusion at Christian colleges and universities – has suddenly become possible. Specifically, the chapter provides an historical overview of three currents of the LGBT movement – the emergence of the LGBT rights movement as a force in U.S. politics, the spread of Gay-Straight Alliances across U.S. schools, and the inroads by LGBT advocates into religious denominations – and argues that the increasing openness of some Christian denominations to LGBT equality in particular has emboldened LGBT and allied students working to advance LGBT equality on Christian college and university campuses. The chapter then provides descriptive statistical data on the presence of LGBT groups and inclusive nondiscrimination statements across all Christian colleges and universities in the United States. The chapter shows that it is when Christian colleges and universities are affiliated with Christian denominations that maintain a historical body of social justice teachings that they are most inclusive of LGBT students.
Committing to the Cause
Authors: Coley Jonathan S.
Published: September 2018

This chapter provides an overview of the three kinds of LGBT organizations at Christian college and universities – direct action groups, educational groups, and solidarity groups – and argues that a correspondence between the ethos of these groups and the identities of participants produces activist commitment. LGBT direct action groups protest their schools’ discriminatory policies toward LGBT people. Perhaps not surprisingly, these groups tend to be led by politicized participants. LGBT educational groups tend to fulfil dual functions – first, providing forums for their participants to collectively discuss their beliefs about LGBT issues, and second, organizing lectures, movie showings, and other events to educate the wider student body about LGBT issues. Because they do not presuppose a commitment to the cause of LGBT rights, these groups tend to be led by religious participants. Finally, LGBT solidarity groups fulfil two kinds of purposes – first, providing a confidential support group to assist LGBT students in their coming out processes, and second, organizing social events that allow LGBT students to meet each other. Because solidarity groups are focused on personal issues facing LGBT people, individuals who identify as LGBT most often lead them. The chapter contributes to sociological theory on activist commitment.
Creating Change
Authors: Coley Jonathan S.
Published: September 2018

This chapter addresses the question of how LGBT activist groups impact Christian colleges and universities. Specifically, the chapter analyses the ways LGBT activist groups change campus policies, by pressuring their schools to adopt nondiscrimination policies inclusive of sexual orientation and gender identity, and campus climates, by working to create campuses where LGBT people can be open about their sexuality or gender identity without fear of bullying or harassment. The chapter shows that LGBT activist groups are most effective at changing campus policies and climates when they simultaneously engage in conversations about Christianity and LGBT rights and thus transform people’s understandings about what it means to be a Christian university, a Christian community, and an LGBT Christian. LGBT activist groups that avoid these conversations are less successful at creating change at their colleges and universities. The chapter draws on insights on social movements and culture to advance sociological theory on social movement outcomes.
Becoming an Activist
Authors: Coley Jonathan S.
Published: September 2018

This chapter analyses the post-graduation political, career, and family plans of students who participate in LGBT activist groups at Christian colleges and universities. Graduates of direct action groups are, perhaps not surprisingly, the most likely to pursue future involvement in social movements and political campaigns, as they have gained skills in organizing and mobilizing other people. Graduates of educational groups tend to pursue humanistic careers, especially religious institutions, because they have gained leadership skills useful for creating change within existing institutions. Graduates of solidarity groups most commonly report changes in their future family plans, such as desires to enter into more equitable marital partnerships and raise tolerant and accepting children, because their organizations have provided them opportunities to reflect on their personal lives. Finally, graduates of all types of LGBT activist groups report immediate changes in their existing relationships with family members and friends, stating that they have found the courage to come out as members of the LGBT community and to discuss LGBT rights issues in their everyday conversations. The chapter contributes new insights on the biographical consequences of activist groups.
Conclusion
Authors: Coley Jonathan S.
Published: September 2018

The conclusion chapter provides vignettes of students who, as a result of participating in LGBT groups at Christian colleges and universities, have come to view themselves as activists. Through these vignettes, the chapter reiterates the central theoretical implications of the book – that varieties of activism exist, and that these varieties of activism have implications for how people can understand participation in activist groups and impacts of activist groups. The chapter also outlines several practical implications of the study for those who want to better understand how to create change on their Christian campuses and for those who wish to support students in their efforts.
