Authors: Araújo Isaac De Sousa , Pinheiro Woneska Rodrigues , Vilar Marcela Oliveira
Published: February 2020

O desenvolvimento da cárie dentária não depende apenas da presença de microrganismos na cavidade bucal, mas também está relacionado com a dieta alimentar, higiene bucal, susceptibilidade do hospedeiro, fator socioeconômico, dentre outros. Objetivou-se investigar a prevalência de cárie dentária em crianças em condição de vulnerabilidade social no município de Crato, CE. Para tanto foi realizado um estudo descritivo de caráter transversal com dados quantitativos. A população do estudo foi composta por crianças de 5 a 13 anos atendidas pelo projeto social Verde Vida no ano de 2018. A coleta de dados procedeu-se através de questionário, seguida pela realização de exame clínico bucal para construção dos índices CPOD e ceo-d. Foi avaliada uma amostra de 52 crianças de ambos os sexos, sendo que 01 possuía dentição decídua, 21 dentições permanentes e 30 apresentavam dentição mista. O CPOD variou entre 0 e 12 e o ceo-d entre 0 e 13, com a média de CPOD e ceo-d igual a 2,17 e 4,77, respectivamente. O número de dentes hígidos oscilou entre 11 e 28, e o total de dentes decíduos presentes na boca de 0 a 20 e a prevalência de cárie dentária encontrada foi de 92,31%. Foi observada uma alta prevalência de cárie dentária na população avaliada, porém os CPO’s médios encontrados não se apresentaram muito discrepantes com os achados em nível territorial brasileiro.

Self-Calibration of the Stereo Vision System of the Chang'e-4 Lunar Rover Based on the Points and Lines Combined Adjustment
Authors: Zhang Shuo , Jia Yang , Peng Song , Wen Bo , Ma Youqing , Qi Chen , Sima Bing , Liu Shaochuang
Published: February 2020

The stereo vision system is the special engineering measurement instrument of the Chang'e-4 lunar rover. It is composed of the Navigation Camera (NavCam) and the Mast Mechanism (MasMec). An improved self-calibration method for the stereo vision system of the Chang'e-4 lunar rover is
proposed. The method consists of two parts: the NavCam's self-calibration and the MasMec's self-calibration. A combined adjustment based on the points and lines is proposed. The baseline constraint of the NavCam is considered. The self-calibration model of the MasMec is established based on
the product-of-exponentials formula. Finally, the premission laboratory calibration and the on-site calibration are carried out. The laboratory calibration shows that the proposed approach has high accuracy. The checkpoint with a distance of about 2.7 m to the left NavCam has a point error
of about 4 mm. Finally, the proposed approach is applied in the on-site calibration.
Reducing Shadow Effects on the Co-Registration of Aerial Image Pairs
Authors: Plummer Matthew , Stow Douglas , Storey Emanuel , Coulter Lloyd , Zamora Nicholas , Loerch Andrew
Published: February 2020

Image registration is an important preprocessing step prior to detecting changes using multi-temporal image data, which is increasingly accomplished using automated methods. In high spatial resolution imagery, shadows represent a major source of illumination variation, which can reduce
the performance of automated registration routines. This study evaluates the statistical relationship between shadow presence and image registration accuracy, and whether masking and normalizing shadows leads to improved automatic registration results. Eighty-eight bitemporal aerial image
pairs were co-registered using software called Scale Invariant Features Transform (SIFT) and Random Sample Consensus (RANSAC) Alignment (SARA). Co-registration accuracy was assessed at different levels of shadow
coverage and shadow movement within the images. The primary outcomes of this study are (1) the amount of shadow in a multi-temporal image pair is correlated with the accuracy/success of automatic co-registration; (2) masking out shadows prior to match point select does not improve the success
of image-to-image co-registration; and (3) normalizing or brightening shadows can help match point routines find more match points and therefore improve performance of automatic co-registration. Normalizing shadows via a standard linear correction provided the most reliable co-registration
results in image pairs containing substantial amounts of relative shadow movement, but had minimal effect for pairs with stationary shadows.
PENERAPAN NILAI-NILAI MODERASI AL-QUR’AN DALAM PENDIDIKAN ISLAM
Authors: Az Zafi Ashif
Published: February 2020

Religious moderation is one of the themes that has been widely discussed in the past few decades. This is an anti-thesis of various intolerance attitudes that befall many circles, whether related to politics, social, or even religion. Intolerance in religion becomes the main focus of many circles. Even the younger generation practice this attitude. This attitude of intolerance is suspected to have entered primary and secondary educational institutions, while the efforts made by many parties in anticipating this movement did not reach its main essence. Intolerance in religion is influenced more by a lack of understanding of religion correctly, though al-Qur'an mentioned many principles and moderate attitudes that can be applied in the education system in schools. To get the principles and values of moderation in the Qur’an that can be applied in the education system in schools, this study uses a thematic method introduced by Fazlur Rahman. From this method, it is produced that the values of moderation in the Qur’an accumulate in aspects of justice, openness, wisdom, and balance. These values are required to always be maintained and become a guideline to achieve the universality of Islam in action. The application of these values in education can be committed with several approaches, namely the values inculcating approach, the cognitive moral development approach, the value analysis approach, the value clarification approach, and the learning approach by doing. Through this approach, moderate attitudes are instilled that can give birth to tolerance, mutual respect, and affection between people.
KRITIK ATAS PANDANGAN WILLIAM M. WATT TERHADAP SEJARAH PENULISAN AL-QUR’AN
Authors: Alwi Muhammad
Published: February 2020

The study of the Qur'an has been a topic of interest to many circles, excluding Western scholars. Many of the themes they promote are generally related to the authenticity of the Qur'an. To get into this problem, many circles start arguing from the history of the Qur'an. It is this theme that William M. Watt is concerned within studying the Qur'an. Watt begins his narrative by referring to the term Ummi referred to by the Prophet Muhammad. Likewise, arguments about the literary tradition of the community are presented by reference to many verses in the Qur'an. The majority of interpretations produced are in sharp contrast to the views of the majority of Muslim scholars, so this study aims to conduct a review of Watt's views using thematic methods. This study concludes that the Qur'anic verses used as the basis for Watt's argument over the history of Qur'anic writing can be categorized into two types; historical arguments and interpretations. In the model of historical argument, Watt tends to assume that the writing tradition among the Arabs is also owned by the Prophet, so that the word of the people attached to the Prophet is understood as the Prophet's ignorance of the ancient scriptures. To reinforce the historical argument, Watt analyzes several passages relating to the term public for reinterpretation. Watt's steps in explaining the Qur'an's writing history tend to differ from many circles. Some historical arguments using the basis of verse tend to generalize their context, thus influencing many subsequent interpretations. This is why Watt's opinion is different from the opinion of the majority of scholars.
INTERNALISASI HADIS KASIH SAYANG DALAM MEWUJUDKAN SOCIAL INTEREST DI ERA DISRUPSI
Authors: Prasetyo Aan Aji
Published: February 2020

Problems raised by technological advances have an impact on the creation of a social order that is uprooted from its roots. The order of values that has long been practiced by society, has gradually faded and in time will disappear. In this context, society has faced a moral crisis. To restore these old values, it is necessary to revive the behaviors that are the main source of social capital by reactivating social interest. However, social interest also has vulnerabilities, so we need another element that can be used as a substitute for this attitude. Therefore, this research offers the concept of compassion as a new form of caring in reviving the morale of society that has increasingly faded. For this reason, this research uses a thematic hadith method, with the aim of collecting hadiths that explain compassion in a comprehensive analysis to find the moral messages contained. This research concludes that compassion can be manifested in many forms which indicate that every Muslim is encouraged to respect, respect and be tolerant of others through the manifestation of compassion and loving attitude. This attitude will give birth to concern among humans in the wider community. In relation to moral formation, the use of traditions about compassion is far more effective in reawakening social concerns in the community so that moral values in the era of disruption are still maintained. As a theological basis, the hadith provides a stronger impetus in creating new community relations in the context of modern society, so that technological progress can be balanced with the progress and development of moral values in society.
MODELING FREEZE AND THAW DAMAGE IN CONCRETE DECKS USING DAMAGE MECHANICS
Authors: Saboori Ashkan , Yazdani Siamak , Reberg Andrew , Yang Mijia , Tolliver Denver , Mamani Sara
Published: February 2020

Research has documented that freeze-thaw cycles (FTCs) deteriorate mechanical properties of concrete such as strength and stiffness. This paper presents a general approach to model the changes in these mechanical properties. It also presents a generalized bounding surface approach, where limit surface is allowed to collapse inward and form a new failure surface (residual strength) corresponding to the number of FTCs. Within this formulation, softening equations for strength reduction and the increase in ultimate strain of concrete under FTCs are proposed. Stress-strain curves are obtained and the anisotropic degradation in mechanical properties is captured. The results show a good correlation with experimental data available in the literature.

Authors: Ryu Gum Sung , Koh Kyung Taek , An Gi Hong , Lee Jang Hwa
Published: February 2020

This paper evaluates the strength, shrinkage and durability characteristics of concrete using 100% fly ash and bottom ash as binder. It is seen that the compressive strength of activated fly ash and bottom ash concrete reaches respectively 25 MPa and 30 MPa, and that the change in strength is insignificant as per the content of bottom ash powder. Moreover, the total amount of shrinkage of the activated bottom ash concrete appears to be larger than that of the activated fly ash concrete. In addition, the drying shrinkage and durable performance of the activated ash geopolymer concrete is verified to be superior to that of ordinary cement concrete.

Published: February 2020

This article addresses the issue of Public–Private Partnership (PPP) as a potential tool for urban renewal, in view of budget constraints and a lack of financial resources that affect public authority. In fact, there is increasing application of PPP, driven mainly by municipalities and other local-level entities. The paper reports on two analyses. The first is a comparative study of 15 cases in Italy. The second is research on experiences in two districts of Budapest, Hungary. These analyses offer proposals to facilitate the application of PPP tools, in light of the Italian technical standard UNI/TS 11453 of 2012. This way it is possible to develop a methodology to properly assess the feasibility and financial viability of a project, ensuring transparency in the execution of European public works.
EXPERIMENTAL STUDY ON HYDRODYNAMIC DRAG OF WALLS IN NATURAL RIVER FLOWS
Authors: Kuwamura Hitoshi
Published: February 2020

Hydrodynamic drag of a free-standing wall partially submerged in inundation flow was experimentally investigated in a natural river. A wall plate and sensors for measuring drag force, fluid velocity, and water depth were installed in a testing frame made of stainless steel. Regulator plates were immersed on the river bed in the up and down streams of the frame to provide a uniform and steady flow in the testing area. The drag coefficient CD was significantly influenced by Froude number Fr, but not by Reynolds number Re. The CD had a minimum value slightly over 1.0 at around Fr =1.0, and increased up to 2.0 with the changes of Fr toward 0.5 and 2.0. The blockage ratio of the wall in the flume showed a large effect on the CD for subcritical flow (Fr <1.0), but little effect for supercritical flow (Fr >1.0). The formula CD =1.0+Fr 2/4, is suitable to the test data for Fr >1.0, but underestimates Fr <1.0.
PERMEABILITY OF TUNNEL LINING WITH AIR/WATER BUBBLES ON CONCRETE SURFACE
Authors: Maeda Tomoyuki , Honma Hiroki , Hirano Masayuki , Yoshitake Isamu
Published: February 2020

Air and water bubbles are likely to remain on concrete sidewalls in tunnel linings, because the sidewalls are generally constructed with a greater slope than a right angle. The bubbles negatively influence the aesthetic of the concrete lining. In addition, concrete with a lot of large bubbles may decrease durability, such as air permeability. Although most tunnel lining is constructed as plain concrete without reinforcement, the low permeability may affect the maintenance and long-term durability of the tunnel. The study aims to examine the effect of bubble distributions on the permeability of concrete lining. Concrete specimens including various bubble distributions are prepared by using variable angle-forms in a laboratory test. Furthermore, the bubble distribution (area ratio) and the permeability are examined in two actual tunnels. This paper presents a relationship between bubble distribution and air permeability based on these tests. The results show that the relationship is a logarithmic curve of the bubble rate and gas permeability.
MODAL PARAMETER ESTIMATION OF LTI SYSTEM USING HILBERT-HUANG TRANSFORMATION OF MEASURED WIRELESS SENSOR DATA
Authors: Teja Meda Vinay , Mahato Swarup , Chakraborty Arunasis
Published: February 2020

An iterative Hilbert-Huang transformation (HHT) based algorithm is developed to extract the modal parameters of a linear time invariant (LTI) system excited by recorded non-stationary ground motion. The acceleration responses are measured using wireless sensors, which are filtered to avoid mode mixing prior to evaluate the instantaneous amplitude and phase using HHT. The band width is adjusted in successive iterations to achieve convergence in modal parameter estimation. The numerical study presented in this work discusses the efficiency of the identification strategy in the light of noise contaminated earthquake responses.
THE CORROSION BEHAVIOR OF WEATHERING STEEL UNDER DIFFERENT CORROSIVE ENVIRONMENTS
Authors: Utsumi Takahiro , Aso Toshihiko
Published: February 2020

Weathering steel is a kind of steel that can reduce the corrosion rate by generating a dense protective rust on the steel surface that exerts anti-corrosion performance. Exposure tests of weathering steel with saltwater spraying were performed under three different conditions. When the consistency of sodium chloride solutions was small (0.5% and 1.0%), the effect of rain rinse was observed. However, large consistencies of sodium chloride solutions provided small differences in rust thickness between open air and under roof conditions. From the results of iron transfer resistance measurements, it was observed that protective rust was generated only in a few cases. This result indicated that generation of protective rust was strongly dependent on the corrosive environment. From the results of exposure tests, it became clear that the change of rust thickness with time can be estimated as an exponential function. The constants in the exponential function can be expressed as a function of consistency of sodium chloride solutions.
BUILDING INFORMATION MODELING (BIM) ROLES IN THE MALAYSIAN CONSTRUCTION INDUSTRY
Authors: Ahmad Latiffi Aryani , Mohd Suzila , Brahim Juliana
Published: February 2020

Building Information Modeling (BIM) represents a new paradigm in the Malaysian architecture, engineering, and construction (AEC) industry. BIM technology provides virtual models (including 3-D models) to generate a building’s entire lifecycle. The model can also be used for analyzing design clashes, project scheduling, cost estimation, and facility management. The use of BIM in construction projects can reduce time to develop a project, reduce construction cost, and increase project quality. This paper aims to explore roles of BIM in the Malaysian construction industry. Semi-structured interviews were conducted with project consultants and BIM consultants involved in two government projects. The projects were the National Cancer Institute (NCI) Malaysia and Sultan Ibrahim Hall (formerly known as the Multipurpose Hall of Universiti Tun Hussein Onn Malaysia, or UTHM). The interviews revealed effects of BIM in both projects and potential improvement in implementing BIM in construction projects in Malaysia. A literature review and the interviews revealed that BIM is increasingly used and accepted by construction players in Malaysia, and is expected to grow in future.

EMPLOYEE EMPOWERMENT IN CONSTRUCTION: A REVIEW OF ISSUES
Authors: Faisal Alazzaz , Whyte Andrew
Published: February 2020

The construction industry is a high-risk commercial sector. As such, concerns regarding performance, waste, health and safety, insurance, legal/budgetary and cost compliances, and client satisfaction levels are an ongoing challenge. An increasing area of focus is human resources and, in particular, productivity. In place of traditional approaches to dealing with employee performance concerns, better job design and work systems are increasingly being seen as essential in alleviating poor employee/ independent-contractor performance. Academic research on employee empowerment in the construction industry has so far been limited and/or haphazard, despite advocates presenting it as a means to deal with worker dissatisfaction, absenteeism, turnover, poor quality work, and sabotage. This paper reviews the literature concerning the utility of employee empowerment in the construction industry, with particular emphasis on its practical benefits. The aim is to provide direction for future research and development in the construction and civil engineering fields.

The limitations of this study include the self-reporting questionnare and the measurmenet of consumers’ recycling intention rather than their actual behavior.
L’Imagination au pouvoir: historia sztuki w czasach kryzysu lat 60./70
Authors: Turowski Andrzej
Published: February 2020

The present paper is reminiscence and an attempt to reconstruct the intellectual heritage of art history as it was practiced at the University of Poznań in the late 1960s and throughout the 1970s in the context of new developments in cultural theory and changing research interests. Besides, it includes the author’s account of his own academic work in that period, began in the 1960s and inspired in particular by the year 1968 that brought a social crisis and a cultural revolution, as well as introduced the element of imagination into academic knowledge and critical thought. The author draws a wide panorama of intellectual stimuli which contributed to an epistemic and methodological turn, first in his own scholarly work and then in the work of some other art historians in Poznań. Those turns opened art history at the University of Poznań to critical reading of artistic practices approached in relation to other social practices and subjects of power. As a result, four key problems were addressed: (1) the position of contemporary art in research and teaching, (2) the necessity to combine detailed historical studies with critical theoretical reflection, (3) the questioning of genre boundaries and ontological statuses of the objects of study and the semantic frames of the work of art, and finally, in connection to the rise of an interdisciplinary perspective, (4) the subversion of the boundaries and identity of art history as an academic discipline. Then the author reconstructs the theoretical background of the “new art history” that emerged some time later, drawing from the writings of Walter Benjamin, the French structuralism, Theodor Adorno’s aesthetic theory, and Louis Althusser’s interpretation of the concept of ideology. Another important problematic was the avant-garde art of Poland and other East-Central European countries, studiedin terms of artistic geography and the relations between the center and periphery. The conclusion of the paper presents a framework marked with the names of Aby Warburg and Max Dvořák, which connected the tradition of art history with new developments, took under consideration the seminal element of crisis, and allowed art historians to address a complex network of relations among the artist’s studio, the curator’s practice, the scholar’s study, and the university seminar, as well as the West, the Center, and the East. At last, the author remembers the revolutionary, rebellious spirit and the lesson of imagination that the Poznań art history took from March and May, 1968.
Od Zamku Berlińskiego do Forum Humboldtów: paradygmat konfliktu w niemieckiej historii
Authors: Bredekamp Horst
Published: February 2020

The lecture concerns the Berlin Palace (Stadtschloss) and presents a view of its long history, starting with its construction in the Baroque style by an artist of the Polish origin, Andreas Schlüter, up to its contemporary reconstruction with a new institutional function (Humboldt Forum). The ten sections of the text not only present architectural and artistic history of this residence but also pivotal historical events and contexts which affected the dimensions and meaning of its functioning. The palace, entangled into German history but also reflecting it, especially as regards the 19th and 20th centuries, becomes both a starting point for an evaluation of this history and posing questions about the future. Along with the ferociously debated, present-day reconstruction and its museum function, it also seems to be a psychogram of diverse stages of the condition of German spirit.

Published: February 2020

Chromosomal diseases are heterogeneous conditions with complex phenotypes, which include also epileptic seizures. Each chromosomal syndrome has a range of specific characteristics regarding the type of seizures, EEG findings and specific response to antiepileptic drugs, significant in the context of the respective genetic etiology. Therefore, it is very important to know these particularities, in order to avoid an exacerbation of seizures or some side effects. In this paper we will present a review of the epileptic seizures and antiepileptic treatment in some of the most common chromosomal syndromes.
Crowdfunding Under Market Feedback, Asymmetric Information And Overconfident Entrepreneur
Authors: Miglo Anton
Published: February 2020

This article is the first one that considers a model of the choice between the different types of crowdfunding, which contains elements of the asymmetric information approach and behavioral finance (overconfident entrepreneurs). The model provides several implications, most of which have not yet been tested. Our model predicts that equity-based crowdfunding is more profitable than reward-based crowdfunding when an entrepreneur is overconfident. This is because the entrepreneur learns from the sale of shares before making production decisions. The model also predicts that an equilibrium can exist where some firms use equity-based crowdfunding, which contrasts the results of traditional theories (which have rational managers), for example, the pecking-order theory. It also contrasts traditional behavioral finance literature (e. g. Fairchild, R. 2005. “The Effect of Managerial Overconfidence, Asymmetric Information, and Moral Hazard on Capital Structure Decisions.” ICFAI Journal of Behavioral Finance 2 (4).) where equity is not issued in equilibrium.

Authors: Branco Diana G. , Campos Joana R. , Cabrita Luís , Evtuguin Dmitry V.
Published: February 2020

The structural features of macromolecular components of cork (suberin, lignin, cellulose and hemicelluloses) from Quercus suber L. used for the production of stoppers were assessed after their isolation and purification. Suberin is the major component of cork (ca. 44%) and is constituted mainly by hydroxy fatty acids (C14–C26). Cork lignin was found to be highly condensed (16.2%) and revealed a syringyl:guaiacyl:p-hydroxyphenyl (S:G:H) ratio of 26:71:3 with predominant β-O-4′ (0.38%), β-5′, β-β and tetrahydrofuran (THF) type (totally ca. 27%) structures. Cork lignin also has a remarkable amount of ferulic acid structures, which are considered the binding point between lignin and suberin. The cellulose of cork cells (17.2%) is a typical cellulose I polymorph with a degree of crystallinity (DC) of 70.3% and an average crystallite width of 3.5 nm. The major hemicellulose of cork is glucuronoxylan (near 6.0%) possessing a molar Xylp:MeGlcpA ratio of 14:1.

Published: February 2020

This study investigated the changes in physicochemical and functional properties of water-soluble protein from mussels (MWP) induced by high-pressure homogenization (HPH). The results indicated that HPH treatment unfolded or disrupted the initial structure of MWP, exposing free sulfhydryl groups and buried hydrophobic groups. As the homogenization pressure increased, the aggregation of MWP particles gradually decreased. Moreover, protein solubility and dispersion stability increased in aqueous solution. Foaming and emulsifying properties were also improved. HPH treatment has proven to be an effective technique for enhancing the functional properties of shellfish protein, and 120 MPa was the optimum homogenization pressure to modify MWP.

When the semi-crystalline polymers undergo shearing during flow, the orientation of the molecular chains are induced. In order to study the effect of polypropylene orientation on foaming, we designed an injection mold with a long flow ratio. The samples were prepared by different process conditions and characterized by polarized Fourier transform infrared spectroscopy (FTIR). The degree of orientation was calculated by infrared dichroism. It was found that the orientation of the amorphous region has the greatest influence, and the subsurface layer in the cross section along the flow direction had the largest degree of orientation. The samples were foaming in a self-made sealed cavity under the same condition. The foamed samples were observed by scanning electron microscopy, and it was found that the shish-kebab crystal structure was induced in the surface layer and the subsurface layer under strong shear force. The shish-kebab crystal structure restricted the space for bubble nucleation and growth, and a large number of sub-micron and nano-scale cells appeared in the space of nucleation and growth. Along the flow orientation direction, the longitudinal and transverse sections of each foamed sample with the degree of orientation decreases, the density of cells and the average diameter of cells increases gradually, and the expansion of the foams have an advantage in the direction of flow orientation. The degree of orientation corresponding to the amorphous ribbon (1153 cm−1) of all the samples were arranged from small to large, and it was found that the expansion ratio decreased when the degree of orientation increased. The effect of orientation on foaming properties of polypropylene provides a new strategy for designing other polymer foams.

The acoustoelastic effect relates the variation of the velocity of a wave propagating in an elastic body with the variation of stress in the same body. Using the acoustoelastic effect, the state of stress of a mechanical component can be evaluated nondestructively by measuring variations of ultrasonic wave velocity. In practical terms, the relation between wave velocity and stress is determined by a constant commonly referred to as acoustoelastic constant. The aim of this work is to experimentally determine the acoustoelastic constant of a woven carbon/epoxy laminate. In tensile tests, predetermined load values were applied to the samples at the same time the time-of-flight (TOF) variation of the ultrasonic wave traveling in the sample was measured. In the experiments, the ultrasonic wave traveled along one of the main fiber directions of the sample and the load was applied in the same direction. The value of the acoustoelastic constant obtained for the laminate was −0.37 ns/MPa with standard deviation of 0.07 ns/MPa. Knowing the acoustoelastic constant of a material, it allows evaluation of the state of stress of the material in question using ultrasonic waves.
Effect of Warm Forging on the Microstructure and Corrosion Behavior of Austenitic Stainless Steel 316LN

Published: February 2020

The as-received as well as deformed microstructure and electrochemical corrosion behavior of warm-forged and annealed 316LN austenitic stainless steel have been investigated by using electron backscatter diffraction (EBSD) and electrochemical corrosion test methods. An attempt has been made to understand the effect of warm forging and annealing on the microstructure and electrochemical corrosion behavior of 316LN stainless steel. As-received and deformed microstructures of a sample were observed by EBSD, and from micrographs, it was observed that the refinement of grain occurs after deformation. Microstructural refinement occurs after appropriate annealing of the forged sample because of the revision of alpha ferrite and strain-induced martensite into austenite, which is formed after forging. Annealing treatment after warm forging gives better mechanical strength and optimum corrosion resistance because of the formation of homogeneous and equiaxed strain-free austenite grains. After warm forging, around 85 % of grains show a low misorientation angle of 2.5°, which shows that a lot of dislocation generation occurred during warm forging deformation and that these dislocations aligned themselves to form subgrain boundaries also known as recovery during annealing dislocation. The corrosion rate drastically increases after deformation but decreases after the annealing of deformed samples, which indicates that after appropriate annealing the corrosion resistance and repassivation capacity of materials improved because of the formation of stable oxide of chromium. The value of corrosion current density (Ecorr) shifted toward the passive direction in the Tafel plot after annealing of deformed samples, which indicates that a more protective passive film of Cr2O3 formed on the surface of the annealed sample after warm forging. The surfaces of the samples after an immersion test in the FeCl3 solution have been observed by scanning electron microscopy, and from micrographs, it has been observed that the number of pits is reduced after the annealing of a warm-deformed sample as compared with undeformed samples. The pitting potential of the samples was calculated in a simulated pressurized water reactor environment using the Tafel potentiodynamic polarization test.
Ancestry.com and the Evolving Nature of Historical Information Companies
Authors: Groot Jerome de
Published: February 2020

This study of the genealogy and biotech company Ancestry analyzes the ways in which the organization has evolved over the past few years. Ancestry is difficult to categorize as a corporate entity. The company trades in servicing both “traditional” types of history (genealogical records) and, more recently, biotech-based investigation through the use of DNA sequencing. Ancestry is highly influential in the way that millions of people around the world access the past. Given this, the company’s shifts in focus are of great interest. Through considering various new elements of the way that Ancestry functions, and illustrating that this complexity is foundational to its purpose, the article suggests the company is redefining what a public historian or public historical institution might be, adding a scientific dimension to historical data and also acting to present a particular model of the past through its advertising campaigns. The article suggests that public history’s models for considering such protean organizations are in need of attention, and the complexity of such a company demonstrates new challenges and opportunities for scholars in the field.
Wip1 regulates Smad4 phosphorylation and inhibits TGF‐β signaling

Published: February 2020

The tumor suppressor Smad4, a key mediator of the TGF‐β/BMP pathways, is essential for development and tissue homeostasis. Phosphorylation of Smad4 in its linker region catalyzed by the mitogen‐activated protein kinase (MAPK) plays a pivotal role in regulating its transcriptional activity and stability. In contrast, roles of Smad4 dephosphorylation as a control mechanism of TGF‐β/BMP signaling and the phosphatases responsible for its dephosphorylation remain so far elusive. Here, we identify Wip1 as a Smad4 phosphatase. Wip1 selectively binds and dephosphorylates Smad4 at Thr277, a key MAPK phosphorylation site, thereby regulating its nuclear accumulation and half‐life. In Xenopus embryos, Wip1 limits mesoderm formation and favors neural induction by inhibiting TGF‐β/BMP signals. Wip1 restrains TGF‐β‐induced growth arrest, migration, and invasion in human cells and enhances the tumorigenicity of cancer cells by repressing the antimitogenic activity of Smad4. We propose that Wip1‐dependent dephosphorylation of Smad4 is critical for the regulation of TGF‐β signaling.

Published: February 2020

Recent rapid technological advancements in cardiac CT have improved image quality and reduced radiation exposure to patients. Furthermore, key insights from large cohort trials have helped delineate cardiovascular disease risk as a function of overall coronary plaque burden and the morphological appearance of individual plaques. The advent of CT-derived fractional flow reserve promises to establish an anatomical and functional test within one modality. Recent data examining the short-term impact of CT-derived fractional flow reserve on downstream care and clinical outcomes have been published. In addition, machine learning is a concept that is being increasingly applied to diagnostic medicine. Over the coming decade, machine learning will begin to be integrated into cardiac CT, and will potentially make a tangible difference to how this modality evolves. The authors have performed an extensive literature review and comprehensive analysis of the recent advances in cardiac CT. They review how recent advances currently impact on clinical care and potential future directions for this imaging modality.
