Authors: Melânia de Jesus Tassini Raquel JESUS , Santos Joseph Fabiano Guimarães , Coelho Maria Emídia de Melo
Published: June 2020

No cotidiano da prática da medicina de urgência e emergência, mais especificamente na terapia intensiva, surgem diversas situações onde o paciente encontra-se na condição de um processo de morte inexorável, e muitas vezes já com o suporte avançado de vida instalado. Diante desta realidade, cada vez mais presente, necessitamos de intervenções que amenizem os sofrimentos consequentes à mesma, em que a capacidade humana de compaixão e misericórdia possam prevalecer. Neste estudo fez-se revisão sistemática, na busca de estudos observacionais e intervencionistas, além de estudos de revisão sistemática e meta-análise, obtidos através de pesquisa eletrônica realizada no banco de dados do Pubmed e Medline. O período pesquisado foi entre 2006 a 2018. Os termos pesquisados foram: “intensive care unit”, “critical care unit”, “palliative care”, “improving palliative care”, “palliative care service”, “palliative care consult”, “end-of-life care”, “comfort care” e “supportive care”. Fez-se descrição didática dos diversos aspectos encontrados na revisão, onde avaliou-se a importância e necessidade da integração dos cuidados paliativos com a terapia intensiva, por se tratar de uma opção com elevada eficiência e eficácia para dar suporte na assistência aos pacientes, principalmente àqueles com doença terminal e seus familiares. Conclui-se ser imprescindível a educação sobre a filosofia, princípios e prática dos cuidados paliativos na equipe multiprofissional, assim como nos especialistas envolvidos no cuidado do paciente.

LITTLE ADULTS: 18TH CENTURY PORTRAITS OF CHILDREN
Authors: Майборода О.А.
Published: June 2020

В статье анализируются образы дворянских детей XVIII века по детским и семейным портретам. Художники изображали детей на полотнах в соответствии с нравственными и социально-общественными понятиями, которые были наиболее предпочтительны в социуме. Демонстрируется связь между культурными изменениями в обществе и изменениями в детском портрете как социальном конструкте, который транслирует представления о ребенке и его натуре. До настоящего времени в научной литературе нет специальных работ по обозначенной теме. При рассмотрении полотен художников XVIII века автор приходит к выводу о постепенном изменении отношения к детям в обществе — от восприятия ребенка как уменьшенной копии взрослого человека до наделения его индивидуальными чертами. На детских портретах первой четверти и середины XVIII века присутствуют те же позы, что и на одиночных портретах взрослых. Одежда, поза, обстановка на картине показывают отношение общества к ребенку, отсутствие ценности детства в то время. С распространением в Европе и затем в России идей Просвещения отношение к детству изменилось. Художники второй половины XVIII века начинают изображать ребенка не только в парадной, но и в обыденной, повседневной обсановке. В детском образе подчеркивается ангелоподобность, дети чисты и неискушенны. По мнению автора, детские портреты, созданные в определенный исторический период,
являются важным визуальным источником для изучения социальной истории.

The article analyzes 18th century children’s portraits and family portraits to investigate aristocratic children images. 18th century artists portrayed children in accordance with moral and social principles accepted by the society of that period. The article highlights the connection between cultural transformations undergone by society and changing methods of depicting children in accordance with people’s attitudes to children and children’s nature. The issue is still largely underinvestigated. Having analyzed children’s portraits made by artists of the 18th century, the author concludes that in the 18th century, social attitudes to children underwent gradual changes. In the first half of the 18th century, children were treated as little adults. Children’s portraits of that period depict children wearing adult-like clothes, standing in adult-like poses. The background, the clothing and the postures manifest a rather perfunctory attitude to childhood. The ideas of Enlightenment which came to Russia from Europe contributed to the transformation of attitudes to childhood. In the second half of the 18th century, artists do not only paint children in ceremonial robes, they also depict children in their everyday environment. Children in paintings are angelic, pure and innocent. The author of the article maintains that, being
an important visual asset, children’s portraits enable a researcher to investigate social history.

The Growing Role of the State in the Family
Authors: Baskerville Stephen
Published: June 2020

The role of the state in the family has been increasing, arguably,since the beginning of modern history. Historical sociologists like CarleZimmerman suggested that modern history has been characterizedby a gradual increase in the power of the state and that this growthis inversely proportionate to the declining importance of the family.The very field and concept of “family policy” presupposes that the fa-mily is a legitimate sphere of life for state intervention and activity. Yetthe intervention of the state may be like the touch of Midas: that whichit touches it destroys. If scholars like Zimmerman are correct, then themore the state intervenes in the family, the more we can expect the fa-mily to decline. This is borne out by recent experience, and very logicalreasons may be adduced for this and very clear manifestations in are-as like family integrity, parental rights, child welfare, and the increasein family-connected bureaucracies associated with the welfare state.Often our only acceptable response to the problems created by govern-ment intervention is more government intervention. Not only can thecure be worse than the disease; the cure canbe the disease. The resultis ever-more-powerful and ever-more-intrusive government bureaucracy– all purporting to solve the problems created by the previously policiesand the previous bureaucracy. The only way to break this vicious cycle isto discard some of our sacred assumptions about what constitutes familyhealth and to accept a new understanding of the relations between thefamily and the state.

Global Mapping of an Exo-Earth Using Sparse Modeling
Authors: Aizawa Masataka , Kawahara Hajime , Fan Siteng
Published: June 2020

We develop a new retrieval scheme for obtaining two-dimensional surface maps of exoplanets from scattered light curves. In our scheme, the combination of the L1-norm and total squared variation, which is one of the techniques used in sparse modeling, is adopted to find the optimal map. We apply the new method to simulated scattered light curves of the Earth, and find that the new method provides a better spatial resolution of the reconstructed map than those using Tikhonov regularization. We also apply the new method to observed scattered light curves of the Earth obtained during the two-year Deep Space Climate Observatory/Earth Polychromatic Imaging Camera observations presented by Fan et al. The method with Tikhonov regularization enables us to resolve North America, Africa, Eurasia, and Antarctica. In addition to that, the sparse modeling identifies South America and Australia, although it fails to find Antarctica, maybe due to low observational weights on the poles. Besides, the proposed method is capable of retrieving maps from noise-injected light curves of a hypothetical Earthlike exoplanet at 5 pc with a noise level expected from coronagraphic images from a 8 m space telescope. We find that the sparse modeling resolves Australia, Afro-Eurasia, North America, and South America using 2 yr observation with a time interval of one month. Our study shows that the combination of sparse modeling and multiepoch observation with 1 day or 5 days per month can be used to identify main features of an Earth analog in future direct-imaging missions such as the Large UV/Optical/IR Surveyor.
Insights into the Formation and Evolution History of the Galactic Disk System
Authors: Han Doo Ri , Lee Young Sun , Kim Young Kwang , Beers Timothy C.
Published: June 2020

We present a kinematic analysis of a sample of 23,908 G- and K-type dwarfs in the Galactic disk. Based on the α-abundance ratio, [α/Fe], we separated our sample into low-α thin-disk and high-α thick-disk stars. We find a

gradient of −28.2 km s−1 dex−1 over [Fe/H] for the thin disk and an almost flat trend of the velocity dispersions of

,

, and

components with [Fe/H]. The metal-poor (MP; [Fe/H] <–0.3) thin-disk stars with low-

 velocities have high eccentricities (e) and small perigalacticon distances (

), while the high-

MP thin-disk stars possess low e and large

. Interestingly, half of the super-metal-rich ([Fe/H]> + 0.1) stars in the thin disk exhibit low-e, solar-like orbits. Accounting for the inhomogeneous metallicity distribution of the thin-disk stars with various kinematics requires radial migration by churning—it apparently strongly influences the current structure of the thin disk; we cannot rule out the importance of blurring for the high-e stars. We derive a rotation velocity gradient of +36.9 km s−1 dex−1 for the thick disk and decreasing trends of velocity dispersions with increasing [Fe/H]. The thick-disk population also has a broad distribution of eccentricity, and the number of high-e stars increases with decreasing [Fe/H]. These kinematic behaviors could be the result of a violent mechanism, such as a gas-rich merger or the presence of giant turbulent clumps, early in the history of its formation. Dynamical heating by minor mergers and radial migration may also play roles in forming the current thick-disk structure.
Renal echinococcosis; the parasite, host immune response, diagnosis and management
Authors: Yousofi Darani Hossein , Jafari Rasool
Published: June 2020

Renal echinococcosis is a rare parasite-caused disease of humans and animals; it makes up about 4% of confirmed cases of cystic echinococcosis. It is a zoonotic disease that occurs in the intermediate hosts harboring the larval stage, the hydatid cyst, of Echinococcus spp. The renal involvement is often asymptomatic or with unspecific signs. Its diagnosis is mostly based on imaging technique. Immunodiagnostic tests are not applicable. Furthermore, because the disease is not common, our knowledge about its different aspects is scarce. In this review, the parasite, host immune response, diagnosis, and management of renal echinococcosis are described.

Published: June 2020

Canola-type genotypes in Indian mustard (Brassica juncea) are a new kind of quality resource developed for their low levels of erucic acid (<2%) and glucosinolate (<30 μmole/g defatted meal) contents. Single-zero (low erucic acid) and double-zero (low erucic acid and glucosinolate content) genotypes of Indian mustard have less vigor. Conventional genotypes (high erucic acid and glucosinolate contents) havea significantly higher seedling vigor index-II (SVI-II) and single-zero genotypes have a significantly higher SVI-I, whereas double-zero genotypes have been observed to have a significantly lower SVI-I and SVI-II. To know the possible reasons for the differences in vigor, the seed quality parameters, reactive oxygen species (ROS) contents (superoxide radicals (O2−·) and hydrogen peroxide), lipid peroxidation, and antioxidant enzyme activity were examined. In the dry seeds, the conventional genotypes revealed lower ROS contents and higher catalase and peroxidase enzyme activity. This trend was reversed in the double-zero genotypes, which could be the reason why they were more susceptible to oxidative damage. During seed germination, an increase in the ROS contents, and corresponding increase in antioxidant enzyme activity, was noticed, which was highest in the conventional genotypes, followed by the single-zero genotypes. Double-zero genotypes showed the lowest increase in ROS contents and antioxidant enzyme activity during this period. This meant that the required attributes were met for maintaining oxidative balance within the cells and triggering physiological activities to reach high vigor. This study proposed 2 causes for the poor vigor of the double-zero genotypes; first, in the dry seeds, the ROS remained high due to low antioxidant activity (ROS scavengers) and the second was less generation of O2−· during germination.
Geochemistry, risk assessment, and Pb isotopic evidence for sources of heavy metals in stream sediments around the Ulukışla Basin, Niğde, southern Turkey
Authors: LERMİ Abdurrahman , SUNKARI Emmanuel Daanoba
Published: June 2020

Concentrations of selected elements (Al, Fe, Mn, Mo, As, Cd, Cu, Cr, Ni, Co, Pb, Sb, and Zn) and Pb isotope ratios were determined in 53 sediments from Alihoca, Gümüş, Horoz, and Çakıt streams around the south-central Taurides (Ulukışla Basin), Niğde, which is a known mining province in Turkey. Several pollution and risk assessment indices were used to assess possible heavy metal pollution in the stream sediments and the associated potential ecological risks. Concentrations of As, Cd, Cu, Cr, Ni, Co, Pb, Sb, and Zn were elevated in the streams located near ancient mines, active mines, and slag piles in the area, suggesting an influence from mining activities. The pollution assessment indices indicated that the sediments were significantly polluted by As, Cd, Sb, Zn, and Pb and moderately polluted by Cu, Ni, Cr, and Co. The sediments show very high potential ecological risk with As, Cd, Sb, and Pb as the principal contributors. Ni, Cr, As, Pb, Zn, and Cd exceeded the probable effect concentrations in most of the samples implying that their concentrations may frequently affect sediment-dwelling organisms. Multivariate statistical analyses indicate that the accumulation of heavy metals in the stream sediments is due to an interplay of anthropogenic activities (mining and agrochemical application) and geogenic processes (weathering of bedrocks and supergene alteration of base metal-rich mineralization). Pb isotopic tracing indicates that total Pb in the sediments (206Pb/207Pb = 1.09–1.29) is primarily from weathering and dissolution of ultrapotassic rocks (206Pb/207Pb up to 1.20) and galena (206Pb/207Pb up to 1.21) from the Pb-Zn-Au deposits in the area with some anthropogenic input from mine slag piles (206Pb/207Pb = 1.10).

Published: June 2020

Concentrations of Al, Fe, As, Co, Cr, Cu, Mn, Ni, Pb, Zn, Hg, and organic carbon, and grain size distribution were investigated in the surface sediments of 7 sampling stations in the Sığacık Bay (western Anatolia) in December 2016. At all of the sampling stations, the concentrations of Pb, Ni, Cr, and As were higher than the average shale values. The highest concentrations of Pb, Cu, Zn, As, and Hg were found at stations near Doğanbey Cape. The possible sources of pollution were evaluated using several parameters: the enrichment factor (Ef), contamination factor (Cf), and contamination degree (Cd). The Ef values ranged between 0.12 and 7.61 in the bay. The high Ef (>1.5) values of Pb, Cu, Ni, Co, and As were assessed to explain the influence of anthropogenic sources. Additionally, the Cf values ranged from 0.46 to 5.61, while the Cd values ranged from 11.69 to 20.45 in the study area. The Cd of the Cr and As ranged between moderate and considerable, and the highest Cd was measured at stations near Doğanbey Cape. Additionally, the pollution degrees were assessed using sediment quality guidelines (SQGs), the threshold effect level (TEL), the probable effect level (PEL), the effects range low (ERL), and the effects range median (ERM). It was demonstrated that the sediments were generally heavily polluted with Cr and Ni, and moderately with Pb and Cu, according to the numerical SQGs. The concentrations of Pb, Cr, Cu, Zn, and Ni were above the TEL, while Cr and Ni were also higher than the PEL levels for all of the samples.

La mascarade entre la féminité et l’insaisissable du féminin
Authors: dos Mares Guia-Menéndez Elisa
Published: June 2020

Le désir de comprendre l’énigme de la féminité a poussé Freud à explorer les mécanismes inconscients. Pour combler certaines lacunes, il a créé un schéma qui conduirait à la féminité accomplie . Joan Rivière part de sa clinique pour questionner les tableaux élaborés par Freud et ses contemporains. Lacan, quant à lui, a incorporé les lacunes dans son enseignement en laissant la place à une autre dimension, celle du féminin, fondamentale pour la vitalité du champ analytique.
Le féminin en question
Authors: Sesé-Leger Sylvie
Published: June 2020

Cet article met en perspective le féminin en question depuis Freud et dans l’histoire de la pensée analytique. Il résulte d’un long travail de séminaire collectif qui démontre la fécondité de cette notion. Le féminin n’étant pas l’apanage des femmes, il s’invite comme épreuve dans la rencontre de l’Autre, que celle-ci soit amoureuse, sexuelle, ou bien transférentielle. Si le féminin n’est ni la féminité ni le maternel, il se transmet, telle une énigme, entre mère et fille.
L’usage clinique de la notion de culture
Authors: Coyer Gilbert
Published: June 2020

Il est important pour les psychologues cliniciens travaillant en situation interculturelle de s’appuyer sur une notion de la culture qui ne soit pas essentialiste, c’est à dire donnée comme une essence intrinsèque à l’individu et non transformable, dépendante uniquement de l’environnement, et dont ses processus de pensée seraient dépendants et non pas acteurs. Une revue historique et conceptuelle de la notion de culture permet de dégager celles qui peuvent s’articuler ou non avec les concepts fondamentaux de la psychologie. En situation la culture doit pouvoir être pensée et analysée avec et dans le cadre clinique.
Utilisation d’une version française transculturelle du temas comme outil projectif et narratif dans l’examen psychologique de l’enfant

Published: June 2020

Quel que soit leur champ d’application, les psychologues sont amenés dans leur pratique aujourd’hui, à rencontrer des personnes de différentes origines culturelles. Cette réalité leur demande de prendre en compte, non seulement les référents culturels des sujets mais aussi les processus psychologiques qu’ils mettent en œuvre pour gérer toutes les situations transculturelles (enfants de migrants ou migrants, minorités, métissages…). Ainsi est né le projet de mettre à la disposition des psychologues français une épreuve projective et narrative inspirée du tat mais représentant une société diverse culturellement, avec des personnages aux physiques variés, dans le but de favoriser les récits et de permettre l’émergence éventuelle de conflits psychiques propres à la construction identitaire dans un contexte de diversité culturelle. Le projet d’une adaptation française transculturelle du temas est ici présenté et deux récits d’enfants recueillis à partir de ses planches sont analysés. Les images ont permis à ces enfants de puiser dans la diversité de leurs références culturelles pour inventer des récits et symboliser ainsi leurs conflits internes.

Published: June 2020

Cet article a pour objectif de discuter les apports des méthodes projectives à la compréhension psychodynamique de la violence sexuelle des femmes. À partir d’un cas clinique, nous montrons en quoi les méthodes projectives permettent de soutenir les processus de symbolisation en regard des difficultés d’intégration de l’expérience subjective traumatique et de convoquer le travail associatif par l’appel fantasmatique et la réactivation d’expériences sensorielles et représentationnelles à partir d’un matériel ambigu ; de rendre compte de la complexité des processus psychiques dans la clinique de l’agir sexuel violent, et enfin, de médiatiser la relation sujet/clinicien.

Office Probing for Congenital Nasolacrimal Duct Obstruction: A Study of Parental Satisfaction
Authors: Goldblum Todd A , Summers C Gail , Eghert James E , Letson Robert D
Published: June 2020

ABSTRACT

Purpose: To determine parental satisfaction with nasolacrimal probings performed in the office without sedation for congenital nasolacrimal duct obstruction.

Methods: We reviewed the charts of 81 consecutive children under 4 years of age who underwent nasolacrimal probings in our office. Sixty-seven caretakers of these children were contacted by telephone to determine parental satisfaction, probing effectiveness, procedural complications, and future recommendations. A comparison between parental satisfaction and patient age, probing effectiveness, and unilateral versus bilateral probings was performed.

Results: Most caretakers (86%) were satisfied with the procedure and most (81%) would prefer the probing to be performed in the office rather than under general anesthesia (6% were unsure). Satisfaction rates were similar between the different age groups (P>.5 by Chi-square analysis), but were slightly lower in the unsuccessful probing and bilateral probing subgroups. Parents of children who underwent both an office procedure and a subsequent procedure under general anesthesia tended to prefer the office-based technique.

Conclusion: The majority of caretakers of children who underwent unilateral or bilateral nasolacrimal probings in the office without sedation were satisfied with the procedure and, when given a choice, preferred it over probings performed under general anesthesia.
Withdrawal Prediction Framework in Virtual Learning Environment
Authors: Hlioui Fedia , Aloui Nadia , Gargouri Faiez
Published: June 2020

Making the most from virtual learning environments captivates researchers, enhancing the learning experience and reducing the withdrawal rate. In that regard, this article presents a framework for a withdrawal prediction model for the data of the Open University, one of the largest distance-learning institutions. The main contributions of this work cover two main aspects: relational-to-tabular data transformation and data mining for withdrawal prediction. This main steps of the process are: (1) tackling the unbalanced data issue using the SMOTE algorithm; (2) voting over seven different features' selection algorithms; and (3) learning different classifiers for withdrawal prediction. The experimental study demonstrates that the decision trees exhibit better performance in terms of the F-measure value compared to the other tested models. Furthermore, the data balancing and feature selection processes show a crucial role for guiding the predictive model towards a reliable module.

Published: June 2020

Visual object tracking remains a challenge facing an intelligent control system. A variety of applications serve many purposes such as surveillance. The developed technology faces plenty of obstacles that should be addressed including occlusion. In visual tracking, online learning techniques are most common due to their efficiency for most video sequences. Many object tracking techniques have emerged. However, the drifting problem in the case of noisy updates has been a stumbling block for the majority of relevant techniques. Such a problem can now be surmounted through updating the classifiers. The proposed system is called the Occluded Object Tracking System (OOTS) It is a hybrid system constructed from two algorithms: a fast technique Circulant Structure Kernels with Color Names (CSK-CN) and an efficient algorithm occlusion-aware Real-time Object Tracking (ROT). The proposed OOTS is evaluated with standard visual tracking benchmark databases. The experimental results proved that the proposed OOTS system is more reliable and provides efficient tracking results than other compared methods.
Biochar as a Conducting Filler to Enhance Electrical Conduction Monitoring for Concrete Structures
Authors: Kamaluddin Siti , Kurniawan Denni , Abu Bakar Muhammad Saifullah , Abu Samah Zuruzi
Published: June 2020

Smart and resilient concrete structures will require building materials such as cements that sense flaws. One mechanism of crack detection in structures is monitoring their electrical conduction. Two mechanisms of charge in cement is ionic movement and moisture diffusion. Carbon rich electrically-conducting char is produced by pyrolyzing rice husks and can be used to enhance electrical conduction in cement. This paper studies the evolution of electrical properties in ordinary Portland cement added with up to 15 wt% rice husk-derived biochar. Resistance of cements decreased with increasing biochar addition while moisture loss and resistance both increase as curing time increases. Cement with 15 wt% biochar experiences the largest moisture loss and the most conducting. This suggest charge transport along percolation paths of biochar particles is dominant mechanism in these materials. Electron microscopy and energy dispersive spectroscopic studies reveal formation of Ettringite phase and good wetting/bonding at the interface of biochar particles and cement.
Fabrication of Fibre Metal Laminates with Multiscale Toughening Mechanisms
Authors: Mahendrarajah Ghowsalya , Kandare Everson , Khatibi Akbar A.
Published: June 2020

Although Fibre Metal Laminates (FMLs) show many advantages compared to other composite materials, their layered structure, a result of bonding dissimilar materials, makes FMLs prone to delamination. Conventional solutions to toughen the metal-composite interface have already reached their limit. For further improvement to the metal-composite interfacial bonding properties, a multiscale approach involving micro/nanotoughening mechanisms needs to be implemented. However, the fabrication of FMLs with controlled toughening at different length scales is complicated. This paper introduces a new methodology to manufacture FMLs having micro-and nanosized features using a 3D interconnected silver nanowire interleave at the metal-composite interface. The effects of processing parameters on the extent and effectiveness of the multiscale toughening mechanisms are presented.

Authors: He Tu Sheng , Xu Yang , Liu Yang , Li Zai Bo , Zhao San Yin , Zhao Xu Guang
Published: June 2020

Taking fluidity and compressive strength of mortar as index, steel slag slag composite admixture replaces cement by 50%. The influence of the fineness and content of steel slag powder on the properties of composite admixture was studied by uniform experimental design. The fitting regression equation between the parameters of steel slag fineness and dosage and the performance indexes is established, and the contour map is drawn. The results show that the predicted value is in good agreement with the measured value, and the correlation coefficient is more than 0.99. Through regression analysis and contour map analysis, it is shown that increasing the fineness of slag powder and reducing the content of slag are beneficial to improving the cementitious activity of slag composite.
Study on Microstructure and Properties of Cu-14Fe-0.05C Alloy Prepared by Drawing
Authors: Guo Wei , Lu De Ping , Jiang Jiang , Liu Ke Ming
Published: June 2020

Cu-14Fe-0.05C alloy was prepared by using the vacuum melting process and then multipass drawing deformation was performed. The results showed that with rise of drawing strain, iron-rich phases in the Cu-14Fe-0.05C alloy gradually change from irregularly distributed coarse dendritic phases in the as-cast state to slender fibrous ones distributed parallel along the drawing direction. The higher the strain is, the slender and denser the fibers are and the more uniform the distribution is. Moreover, more interfaces are found between copper matrix and iron-rich phases and the hardness and resistivity of the alloy become higher.

A novel end-functionalized glycopolymer poly (3-O-methacryloyl-D-glucofuranose) -b-poly (2-Diethylaminoethyl Methacrylate) (PMAGlc-b-PDEA-ZnTAPc) with zinc (II) teraamaninophthalocyanine was synthesized. First, a pH-responsive copolymer PMAIpG-b-PDEA was synthesized via reversible addition-fragmentation chain transfer (RAFT) polymerization. Then PMAIpG-b-PDEA reacted with ZnTAPc and deprotected to form a water-soluble and pH-responsive photosensitizer. The structure of the PMAGlc-b-PDEA-ZnTAPc was characterized by 1H NMR and GPC. The photophysical properties were evaluated by UV-Vis and fluorescence spectra. The PMAGlc-b-PDEA-ZnTAPc can generate singlet oxygen species with good singlet oxygen quantum yields (Φ△=0.38), which is believed to be the major cytotoxic reactive oxygen species (ROS) for photodynamic therapy. The ZnPc functionalized glycopolymer will be used as a potential photosensitizer in the fields of photodynamic therapy.

In order to reduce the environmental burden and the energy consumption of PVA fiber reinforced high toughness cementitious composites, special focus is placed on the influence of fly ash type and content and curing type on the flexural performance of high toughness cementitious composites through four-point bending tests. The high toughness cementitious composites without fly ash have been used in the program for comparison purpose. The tests results show that, compared with the basic high toughness cementitious composites, the flexural strength decreases and the deflection increases with the s/b increasing when the fly ash is added. The increase in fly ash content results in an improvement of strain hardening property and increases in both flexural strength and deflection, which show that fly ash is benefit to the pseudo strain hardening performance. However the effects of fly ash type and curing type are not obvious on the load but obvious on the deflection. The deflection of high toughness cementitious composites with type I fly ash or water curing is higher than that of type II or standard curing. It is demonstrated that all the high toughness cementitious composites studied in this paper exhibit strain-hardening and multiple cracking through adding fly ash.

The surface treatment conditions of a plastic surface are related to the quality of finished products. Usually, more than 20 causes dominate the success of electroplating for acrylonitrile butadiene styrene (ABS). Thus, the quality control is very complicated and challenging. Even nowadays, most of the production quality still relies on the operator's experience and intuition. This research takes a company of water hardware in Taiwan as the research object. We propose a revolutionary concept of quality management, combining artificial intelligence and surface treatment process altogether. We set up a parameter monitoring system during production to predict the quality of ABS metallization using neural network models such as artificial intelligence forms the basis of the intelligent manufacturing system. It can be used as a quality control tool to improve quality yield and industrial competitiveness. Totally 13 operational parameters (causes) and one quality parameter (consequence) of the electroplating tanks were collected from time to time to build the NN models. Interestingly, we finally find the fuzzy NN model performs better than the precise NN model. We conclude this is resulting from the limitation and vagueness of data.

The objective of this research was to reduce defects in the forming process of fired clay floor tiles by modifying the parameter settings of the influential factors using the Six Sigma approach. The current process had 152,871.16 DPPM (Defect Parts per Million). The main cause of this problem was the rough surface problem in the forming process. The five steps of the Six Sigma quality improvement approach were exercised in this research, i.e. define, measurement, analysis, improvement, and control phases, respectively. This research started by studying in details of the production process to find relevant factors that could cause a rough surface defect. The main factors were selected and analyzed by Failure Mode and Effect Analysis (FMEA). After that, the settings of each factor were discovered by applying the Design of Experiment (DOE) approach. The results showed that the appropriate settings were the sieve size of pan mill setting to 18 Mesh and the size of sieve holes at pan mill setting to be uniformly distributed. It is found that the defect was reduced to 49,151.14 DPPM, which is 67.85% of the defect before the improvement.

Polymeric composite materials with natural renewable fillers are materials that are environmentally sensitive and can be an important alternative to conventional materials. One of the possibilities of using natural fillers is to use natural secondary sources. This paper describes the use of natural waste produced in the processing of palm oil fruits. The experiment describes a change in tensile strength due to an aging of the epoxy resin-based material and particles prepared from palm fruit (PKS). Specifically, the concentration was 30 wt. % and particle size up to 100 μm, 100-200 μm and 200-300 μm. To simulate the aging of the material, a climatic chamber was used which, at regular intervals for 840 hours, changed the ambient temperature from +70 ° C to-40 ° C and humidity. This process caused a decrease in tensile strength of 18.73 MPa for the unfilled epoxy resin and up to 19.27 MPa for the composite system. Comparison with unfilled resin was used to describe the effect of PKS particles on the aging rate. Interphase interaction was described by electron microscopy.

The current composite pipes such as E-glass have better properties compared to metallic pipes. However, these pipes are prone to failure during its service life. In contrast, natural fiber such as basalt fiber composite pipes has better mechanical characteristics compared to current composite pipes. Hoop tensile, longitudinal tensile and internal pressure loads were carried out through experimentally and numerically investigation on the basalt/epoxy and E-glass/epoxy pipe performance. The basalt/epoxy and E-glass/epoxy composite pipes have been manufactured with ±55o winding angle using dry filament winding with impregnation of epoxy resin used Vacuum Infusion Process (VIP) technique and investigated. Basalt and E-glass composite pipes with winding angles of ±45o, ±55o, ±65o, ±75o were fabricated in order to assess the optimal winding angle which can resists the subjected loads. There were good agreement between numerical and experimental results have been recorded. For internal pressure test, the basalt pipes have more internal pressure carrying capacity more than E-glass by 2.41%. Through this investigation, can be concluded that the natural based fiber of basalt can be used as a suitable replacement than E-glass, has further advantages of being cheap, abundant, renewable and easily recyclable. The also possess high strength, excellent flexural stiffness to cost ratio and low thermal conductivity

Sidoarjo mudflow (SM) is a new cementitious material originating from a natural disaster of volcano mudflow in Porong, Sidoarjo, East Java, Indonesia. Some investigations mentioned that the material of SM is rich in Si, Fe, Al and Ca content. The content of Si and Al were considered to be able to generate the gel of Si-O-Si and Si-O-Al in the geopolymer binder. However, the feasibility of SM material as an alternative binder in geopolymer still needs to be investigated in this study. The production of SM material was calcined at the temperature of 400°C up to 900°C which the optimum calcination temperature was about 700°C. This material was called as volcano meta ash (VMA). The analysis of XRD showed that the geopolymer binder of VMA, FA_VMA, and FA had the crystalline in quartz, mullite, magnetite, hematite, and rutile. The analysis of FTIR described that the geopolymer binder of VMA and FA_VMA had similar stretching in the gel of Si-O-Si and Si-O-Al to the geopolymer binder of FA. However, the stretching and bending of H-O-H in the geopolymer binder of VMA and FA_VMA were less than the geopolymer binder of FA. Finally, the analysis of SEM showed that the geopolymer binder of VMA has less concavity and more gel compared to the geopolymer of FA_VMA and FA.

Published: June 2020

Horizontal-to-vertical spectral ratios (HVSRs) of microtremor-generated ambient noise were obtained at 41 borehole sites in South Central Ontario in the 2015-2017 field seasons, where in-hole measurements of shear wave velocity-depth structure had previously been
made. It has been shown that HVSR spectral resonance maxima are directly correlated either to the presence of large seismic impedance contrasts within the unconsolidated sediments above the bedrock contact, or to the sediment-bedrock boundary. Ongoing research is currently examining the peak
amplitudes and shapes of the HVSR resonance maxima in order to correlate with known subsurface structure of unconsolidated sediments in Canada. This present work is a contribution towards such correlations with respect to variable shear wave velocity structure, as shown through comparison of
downhole velocity logs with co-located microtremor HVSRs.

There is disagreement about entitlement to, and the scope, of intellectual property rights over research knowledge. This article explores jurisprudential perspectives on ownership of research knowledge. It also features the conflict between African and western conceptions of intellectual property, and how this has affected the exploitation of indigenous knowledge with the resultant impact on traditional knowledge institutions. In modern times, the allocation of rights is relatively settled in such relationships as between employer and employee, the researcher and the funder. Between researcher and publisher, digital technology, which ensures wider circulation, has led to claims for a re-definition of the relationship under which the researcher traditionally licensed his copyright to the publisher. A similar re-definition is called for with respect to research subjects in certain research environments. In particular, the result of research conducted with user-generated data in multi-sided business models like social media sites is implicated. The research finds that there is no generic solution that will apply to all relationships but that laws should be tailored to each relationship pair, in line with the suggestions in this paper. African traditional knowledge is denied protection by criteria such as non-disclosure because of the African collectivist notion of person. While Africans are collectivist, westerners are individualistic. It is concluded that on closer inspection there are analogues in African and western notions of intellectual property that could be used to resolve seeming conflicts and protect traditional knowledge.
