Abnormal Returns From Hedging, Firm Size, and the Fama and French Multifactor Models
Authors: Nelson James M.
Published: March 2023

I use the Fama and French (2015) five-factor model to reexamine the seemingly anomalous result of Nelson, Moffitt, and Affleck-Graves (2005), who document significant positive abnormal returns for firms that hedge. Contrary to their results, using the five-factor model on a new sample of U.S. firms from 2013 – 2021, I observe significant negative monthly abnormal returns of -0.190% (-2.26% annually) for firms using derivative securities (hedgers). My result is consistent with poorly diversified managers engaging in costly hedging behavior that benefits management at the cost of shareholders. When I divide the sample by size (total assets), I find that the significant negative abnormal returns are confined only to large firms, offering no support for the economies of scale or managerial sophistication hypotheses.

3D bioprinting strategies and their application in studies in vivo and in vitro animal models for skin regeneration: a concise systematic review and meta-analysis
Authors: Mauro Rodrigo Souza , Zotarelli-Filho Idiberto José
Published: March 2023

Introduction: Annually, 50% of medical expenses worldwide stem from damage to the body's tissues and organs. Large skin defects can be caused by tumor excision, venous ulcers, diabetic foot ulcers, and burns. The 3D bioprinting of skin has an advantage compared to other technologies for skin substitutes, the capacity for directional and spatial handling at the cellular level with variable density. Objective: It was to identify the most efficient 3D bioprinting strategies and their application in studies in vivo and in vitro animal models, to demonstrate state of art in skin regeneration, and to direct new clinical research with translational studies. Methods: The rules of the Systematic Review-PRISMA Platform were followed. The research was carried out from November 2022 to February 2023 and developed based on Scopus, PubMed, Science Direct, Scielo, and Google Scholar. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results: A total of 237 articles were found and 97 articles were evaluated in full, and 16 were included and described in the present study. According to the GRADE instrument, most studies (X2 =90.5%>50%) followed a controlled clinical study model and had a good methodological design. the biases did not compromise the scientific basis of the studies. Conclusion: Most organotypic skin models have an epidermal layer of keratinocytes and a dermal layer of fibroblasts embedded in an extracellular matrix-based biomaterial. Furthermore, skin comprising epidermis, dermis, and hypodermis stratified with blood vessels, nerves, muscles, and cutaneous appendages can be fabricated. These findings provided evidence for further advances in translational studies in humans.

Authors: Favoni Célio , Mendes Gerotti Franco Nathália
Published: March 2023

Potencial de consumo reflete um limite superior para as transações que podem ocorrer numa determinada localização, quando são consideradas todas as unidades vendedoras e compradoras de uma categoria de bem ou serviço. Assim, estudos voltados para o tamanho do mercado consumidor são importantes, especialmente para identificar o perfil de gastos dos indivíduos de diferentes regiões e classes socioeconômicas. Diante do exposto, o objetivo deste artigo é quantificar o potencial de consumo, para o ano de 2019, dos municípios que compreende a microrregião de Jaú/SP. Trata-se de uma pesquisa quantitativa onde os dados foram extraídos de institutos governamentais e do Índice de Potencial de Consumo (IPC Maps). Para a definição de classes de rendimento foi adotado o Critério de Classificação Econômica Brasil. Os resultados indicaram que a microrregião possui mais de 389 mil habitantes, 96,6% vivem em área urbana e 60% são economicamente ativos (entre 15 e 60 anos). O Potencial de Consumo foi estimado em R$ 9,6 bi (2019), sendo que 66,9% estão concentrados nas cidades de Jaú (39,3%), Pederneiras (11,6%), Barra Bonita e Igaraçu do Tietê (16%). A maior parcela do consumo da população foi com habitação (27,48%), seguido por despesas com beleza, empregados, serviços (17,22%). A classe B foi a responsável pelo maior volume de gastos em produtos e serviços com 44,1% do total. A classe C produziu um gasto de mais de R$ 3,4 bi, o que representou 35,2% do total.

Zur Organisation des Töpferhandwerks in Noricum. Familienunternehmen oder Großbetrieb?
Authors: Auer Martin
Published: March 2023

Keramikproduktion in römischer Zeit wird meist mit Drehscheibe und Töpferofen in Verbindung gebracht. Die Analyse von während der Kaiserzeit in der Provinz Noricum verwendeter Keramik zeigt jedoch, dass für die Herstellung der  oftmals als typisch für Noricum angesehenen  nicht zur Gänze oxidierend gebrannten Keramik weder das eine noch das andere vorauszusetzen ist. Auf Grundlage der archäologischen und archäometrischen Daten zur in Noricum hergestellten Keramik wird, gestützt auf ethnoarchäologische Analogien, ein Bild eines möglichen Produktionsumfeldes entworfen. Dabei weisen Unterschiede in Gefäßform, -verzierung und -technologie auf das Vorhandensein unterschiedlicher Töpfergruppen hin. Innerhalb dieser wird Knowhow tradiert, womit Lernnetzwerke entstehen, die sich im archäologischen Material als Keramikregionen widerspiegeln. Die Veränderung des Repertoires eines Lernnetzwerkes wird meist durch reziproke Beeinflussung der Töpfergruppen initiiert. So lässt sich ein interregionaler Austausch bezüglich einiger stilistischer und morphologischer Keramikeigenschaften festmachen. Die Töpferwerkstätten selbst sind in Noricum archäologisch unzureichend erforscht. Bislang beschränken sich die Befunde auf Töpferöfen, ohne dass zugehörigeWerkstattbefunde bekannt sind. Diese Situation lässt auch keine Aussagen zu den in den Öfen hergestellten Produkten zu. Es ist allerdings festzuhalten, dass bislang keinerlei Ausschussware der nicht zur Gänze oxidierend gebrannten Keramik mit diesen in Verbindung gebracht werden kann. Damit bleibt eine Charakterisierung des Töpferhandwerks in Noricum auf die Keramik selbst angewiesen. Diese lässt im ethnoarchäologischen Vergleich darauf schließen, dass die nicht zur Gänze oxidierend gebrannte Keramik in Noricum in Betrieben hergestellt wurde, die nicht als Großbetriebe zu charakterisieren sind, sondern sich im Umfeld von household production/industry bis zur workshop industry, in Ausnahmefällen und zeitlich begrenzt auch village industry bewegen.

Fingierte Tradition und kulturelles Gedächtnis - Die Aneignung der Vergangenheit im Siedlungswesen der mitteleuropäischen Latènezeit
Authors: Wendling Holger
Published: March 2023

Die häufige räumliche Bezugnahme urgeschichtlicher Grabhügel und befestigter latènezeitlicher Gehöftsiedlungen, sogenannter Viereckschanzen, scheint kein zufälliges Phänomen darzustellen. Mitunter wurden die Wall-Graben-Anlagen unmittelbar an ältere Hügelmonumente angebaut oder in deren direkter Umgebung errichtet. Die Analyse einer Stichprobe süddeutscher Viereckschanzen lässt Lage- und Kombinationsmuster erkennen, die teilweise mit kosmologischen Vorstellungen der keltischen Bevölkerung zu erklären sind. Die bewusste Platzwahl deutet eine gezielte ideologische Anlehnung an die herausragenden Erinnerungsorte an. Ur- und frühgeschichtliche sowie ethnographische Beispiele für ähnliche Phänomene einer Korrelation von Siedlung und Bestattungsplatz bieten Interpretationspotential für die eisenzeitliche Erinnerungskultur Mitteleuropas. Der ostentative Rückgriff auf ältere Monumente diente der Aneignung der Vergangenheit sowie der Schaffung (fingierter) Traditionen und sollte hierdurch wirtschaftliche und politische Machtstrukturen legitimieren und konsolidieren.

Art und rock-art of the Kimberley, Northwest Australia: Narratives, interpretations and imaginations
Authors: Porr Martin
Published: March 2023

This chapter introduces some issues related to the different interpretations and narratives that have been put forward in relation to the Indigenous rock-art of the Kimberley, Northwest Australia. At the centre of inquiry is an examination of the construction of European narratives around these images in their respective historical context. The earliest interpretations were put forward by British explorers and were constructed within the racist and evolutionistic frameworks of the 19th century. These narratives were intimately bound to the contemporary colonialist experience. However, it is also shown that certain elements of these interpretations have lasting effects that resonate until today. Interpretations about the art and the rock-art of the Kimberley find their place today in disputes over the control over land and resources between Aboriginal and other interest groups in post-colonial Australia.

Archäologiegeschichte als Wissenschaftsgeschichte. Über Formen und Funktionen historischer Selbstvergewisserung in der Prähistorischen Archäologie
Authors: Veit Ulrich
Published: March 2023

Ansätze zu einer Geschichte der (Prähistorischen) Archäologie sind, gerade im deutschsprachigen Raum, fast so alt wie das Fach selbst. Entsprechende Studien entstanden zunächst primär in legitimatorischer Absicht. Sie sollten dem jungen Fach eine historische Identität und damit eine Legitimität verschaffen, die es zunächst nicht besaß. An diese Anfänge der Fachgeschichtsschreibung schlossen die wissenschaftsgeschichtlichen Bemühungen nach 1945 ohne wirklichen Bruch an. Seit den 1970er Jahren trat neben die üblichen ideen-, methoden- und institutionsgeschichtlichen Studien verstärkt eine kritische sozialgeschichtliche Perspektive, in der konsequenter auf den Zusammenhang zwischen Archäologie und Gesellschaft abgehoben wurde und so die Abhängigkeiten des Faches vom Zeitgeist durchschaubar gemacht wurden. Auch ging es in entsprechenden Arbeiten darum, die nach 1945 weithin dominante Vorstellung vom vermeintlich unpolitischen Charakter des Faches zu widerlegen und die Verstrickungen auch prominenter Fachvertreter mit den Unrechtssystemen des 20. Jahrhunderts off en zu legen. Erst in jüngerer Zeit wurden darüber hinaus vereinzelt auch andere Formen der Wissenschaftsgeschichtsschreibung erprobt – angeregt v. a. durch Entwicklungen in anderen Bereichen wie der Geschichtswissenschaft oder der Wissenschaftssoziologie. Heute eröffnet insbesondere der practical turn der aktuellen Wissenschaftsgeschichtsschreibung interessante Perspektiven für die Archäologiegeschichtsschreibung. Wie eine solche Perspektive aussehen könnte, wird im zweiten Teil dieses Beitrags dargelegt und an verschiedenen Beispielen erläutert. Am Ende steht der Versuch einer Systematik möglicher Formen und Funktionen der Archäologiegeschichtsschreibung. Darüber hinaus wird die Frage erörtert, welche Anforderungen an eine zeitgemäße Archäologiegeschichte zu stellen sind und was eine solche für das Fach als Ganzes zu leisten vermag.
Is Narrative Necessary?
Authors: Pluciennik Mark
Published: March 2023

How important is traditional narrative structure (stories with an explicit beginning, middle and end) for archaeologists? To answer this question fully would demand attention to human and historical ontologies and archaeological epistemologies, as well as analysis of the kinds of pasts archaeologists prefer to present. In their favour it is here argued that historical narratives are generally complex (for example, in comparison with those preferred by practitioners of the hard sciences, who typically find reductionism the most powerful methodological tool). Narratives may even in some way map onto natural and common structures of human experience. But they also perhaps have a particular affinity to archaeological practices, with the chronological sequence of narrative reflecting in reverse order the process of actual or metaphorical excavation, and hence mimicking the reconstruction of a past told as cause and effect. Narratives can also off er a sense of coherence, resolution and closure, which may encourage a kind of intellectual conservatism. So too may socio-political pressures to conform with existing dominant narratives within the profession. However, despite the potential pitfalls of too strong an adherence to narrative form, and the values of alternative modes of presentation such as non-narrative evocation, it is suggested that narrative should remain an important style of archaeological explanation, albeit with a commitment to open-endedness and an awareness of the possibilities of life beyond narrative.

‚Frühes Griechenland‘. Zum ‚Problem‘ des Orients in fundierten Geschichten des Okzidents
Authors: Schweizer Beat
Published: March 2023

In der Klassischen Archäologie, allgemeiner der Klassischen Altertumswissenschaft gibt es eine lange Diskussion zu den Einflüssen des Orients auf das Griechenland der homerischen Zeit. In dem Beitrag wird versucht, sich dieser Problemstellung über die Konzepte der 'fundierenden Geschichte' oder der 'intentionalen Geschichte' zu nähern. Diese Ansätze zielen auf Geschichte und Geschichtswissenschaft in ihrer gesellschaftlichen Funktion für die Traditions- und Kontinuitätsstiftung sowie die Ab- und Ausgrenzungspraktiken auch der modernen Welt. Davon ausgehend werden einige Abschnitte archäologischer Texte angeführt, die über bestimmte Erzählmuster ein ›orientalistisches‹ Geschichtsbild erzeugen.

Heinz Gau – Ein Greifswalder Prähistoriker im nationalsozialistischen Deutschland
Authors: Rauchfuß Björn
Published: March 2023

Die Geschichte der Prähistorischen Archäologie Deutschlands während des »Dritten Reiches« und das Verhältnis ihrer Fachvertreter zum nationalsozialistischen System werden seit mehr als 20 Jahren verstärkt aufgearbeitet. Im Zentrum des Interesses stehen allerdings meist Wissenschaftler, die dem nationalsozialistischen Regime besonders engagiert zuarbeiteten und – sofern sie den Zweiten Weltkrieg überlebten – in der Regel auch wieder eine Anstellung im Fach fanden. Weniger Berücksichtigung finden hingegen junge Nachwuchswissenschaftler, deren wissenschaftliche Laufbahn nach 1933 begann und durch ihren Tod im Verlauf der Kriegsjahre 1939 bis 1945 sehr früh endete. Am Beispiel des Greifswalder Prähistorikers Heinz Gau wird die Biographie eines solchen jungen Prähistorikers im nationalsozialistischen Deutschland untersucht. Besonderes Augenmerk gilt dabei seinem Studium, seiner kurzen wissenschaftlichen Laufbahn und den Verflechtungen mit unterschiedlichen Parteigliederungen des »Dritten Reiches«. Mithilfe von Gaus' Texten wird untersucht, welche ideologische Haltung er zum Zeitpunkt der Niederschrift einnahm.

Britain in the Awareness of Muslim Literature; Early Historical and Geographical Knowledge until the time of al-Idrīsī (217 AH/ 833 CE – 560 AH/ 1165 CE)
Authors: Naḥee Awaḍ
Published: March 2023

Muslim authors paid a significant interest in European peoples and countries in the view of growing the relationship between Muslim World and Medieval Christian Europe and the flourish of authorship in Muslim scholarship. In fact, a part of the Muslim's interest was given to the British Isles in spite of it is far distance of Muslim lands. Therefore, the present article focuses on principle significant questions; what was Britain for early Muslim authors? and what were the most important reasons for interesting those Muslim authors in it, and what were the most effective factors contributing in developing such interest until the mid-6th AH/ 12th century CE when the geographer al-Idrīsī was alive. Hence, the researcher has to investigate the beginnings of the term "Britain" in Muslim traditional sources since the establishment of authorship in the Muslim world, particularly during first quarter of the 3rd AH/ 9th CE century when the first reference to "Marṭāniyah" was recorded. The al-Idrīsī's account on the British Isles is worthy to examine since he sheds light on its major islands, described in detail the most important British towns and cities in his time, and some of its well-known rivers. He also tried to determine the distances between some of these cities and towns by the mile, with some references to political and economic conditions in the British Isles in his time. All that clarifies the extent of early Muslim interest in the British Isles, seeming limited to the geographical knowledge among most Muslim writings during the period under study.

Los objetivos de esta investigación fueron evaluar: 1) la resistencia a distintas concentraciones de cloro de las cepas bacterianas aisladas del agua pozos artesianos, y 2) la degradación de gasolina y diésel de las bacterias gram negativas aisladas de aguas costeras. Se aislaron 64 cepas bacterianas del agua de 53 pozos artesianos ubicados a las márgenes del río Huacapa en Chilpancingo, Guerrero, México, asimismo, se aislaron 20 cepas bacterianas gram negativas de la playa Caleta, y 17 de la playa Caletilla en Acapulco, Guerrero, las cuales se cultivaron en medios con 300 µL o 500 µL, tanto de gasolina como de diésel; estos compuestos actúan como fuente de carbono y energia. Se caracterizaron 26 cepas de interés médico en agua de pozos artesianos, donde Acinetobacter spp. y A. lwoffii fueron resistentes a una concentración de 2,0 mg L-1 de cloro, mientras que Escherichia coli, indicadora de contaminación fecal, se aisló del agua de cinco muestras: una, a la entrada del río al área urbana (sector I); una, en la parte media del área urbana (sector II); dos, a la salida del área urbana (sector III), y finalmente una, del área cercana al poblado de Petaquillas (sector IV), también se aislaron cuatro cepas de E. coli  de la playa Caleta y cinco de la playa Caletilla; ninguna cepa utilizó gasolina o diésel como sustrato.
Effect of Post-harvesting with Different Photoperiods under Artificial Light Sources on Nitrate and Vitamin C Contents in Hydroponic Green Oak Lettuce
Authors: Htwe Nang Myint Phyu Sin , Rawangpai Maneerat , Ruangrak Eaknarin
Published: March 2023

Green oak lettuce (Lactuca sativa L.) is a popular vegetable for consumers, but it is concerned about nitrate contamination that may harm human health. However, light can affect nitrate reduction and contribute to the accumulation of vitamin C in vegetables. Therefore, this study focused on the effects of post-harvesting with different photoperiods under artificial light sources on vitamin C and nitrate content in hydroponic green oak lettuce. Green oak lettuces were grown in the NFT system, harvested, and post-harvested under Bulb-LED (Experiment I), Bar-LED (Experiment II), and fluorescent lamp (FL) (Experiment III) for 6, 12, and 24 h photoperiods and replaced the nutrient solution with tap water. The nitrate content was significantly reduced after post-harvesting for 12 h photoperiods under FL (9,012 µg NO3- -N/g dry weight) followed by Bulb-LED (13,985 µg NO3- -N/g dry weight) and 24 h photoperiods for Bar-LED (10,727 µg NO3- -N/g dry weight). Vitamin C content was highest after post-harvesting for 24 h photoperiods under Bar-LED (45.47 µg/ml), followed by Bulb-LED (44.73 µg/ml) and FL (35.40 µg/ml). Post-harvesting with artificial light sources for 12 to 24 h photoperiods can improve hydroponic green oak lettuce quality.

Published: March 2023

Monthong durian is a durian species mainly cultivated in Thailand. The rind makes up about 60-75% of whole fruit and is often discarded. Here, we evaluated the effect of durian rind, specifically the inner white peel, as a supplement for a fish diet on the growth performance and disease resistance against Aeromonas hydrophila in Red Tilapia. Fish with an initial average weight of 42.68 ± 0.11 g were fed diets supplemented with durian rind at 0, 10, 15, and 20% for 140 days. Subsequent results showed that growth performance in terms of weight gain, average daily gain, length gain, and specific growth rates were not significant among treatments (P > 0.05). In addition, the feed conversion ratio and survival rate of fish fed with diets supplemented with durian rind were also not significantly different from the control (P > 0.05). After the 140-day feeding trial, fish were injected intraperitoneally with A. hydrophila, and the cumulative mortality was recorded for 14 days. The survival rate of fish-fed durian rind-supplemented diets at all levels was higher than that of the control. The highest survival rate and relative survival percentage were fish fed with 10% and 15% durian rind in the diet. Taken together, the white peel of the durian rind can be a potential fish feedstuff and can act as a natural antibiotic to improve fish resistance against A. hydrophila. Recommended level of durian rind supplementation is 10%-15% in the diet which will not affect growth but can enhance disease resistance to A. hydrophila.

Authors: Feng Chunhua
Published: March 2023

In this paper, a class of nonlinear predator-prey models with three discrete delays is considered.
By linearizing the system at the positive equilibrium point and analyzing the instability of the linearized system,
two sufficient conditions to guarantee the existence of positive periodic solutions of the system are obtained.
It is found that under suitable conditions on the parameters, time delay affects the stability of the system.
The present method does not need to consider a bifurcating equation which is very complex for such a predator-prey model with three discrete delays.
Some numerical simulations are provided to illustrate our theoretical prediction.

Published: March 2023

Shale reservoir has tight reservoir, ultra-low permeability and poor development of natural fractures, which need to be completed by fracturing reconstruction. There are some problems in conventional fracturing fluid construction, such as serious reservoir damage, poor salt resistance, inability to reuse flowback fluid, poor dispersion and wetting change performance. According to the characteristics of reservoir and the problems existing in the construction, a hydraulic fracturing fluid system for shale oil reservoir with surfactant as its main component has been developed. There is no residue after the thickener is broken, and the damage to the reservoir is small. It's salt resistant is 100000mg/L, can realize the reuse of flowback liquid and reduce the oil water interfacial tension to 10-3mN/m level because of good dispersion. At present, the application effect is good at the 725 strata of 13 Wells in H100 platform.
Emissivity Influence on Thermocouple Correction
Authors: Cai Mengyin , Huang Qinghuang , Yue Lingling , Wang Peiyong
Published: March 2023

The reading of a thermocouple is not equal to the gas temperature because of the complicated heat transfer process among the thermocouple, the gas, and the environment. So the corrections for thermocouple measurements are necessary to obtain the real gas temperature. The current correction methods using multiple thermocouples assume that the thermocouples have the same surface emissivity. However, the emissivity of a thermocouple depends on its surface condition, and the emissivity of the thermocouples normally are different. CFD simulations are carried out to study the influence of emissivity difference on the correction accuracy. For the extrapolation method, the correction accuracy could be improved or weakened depending on the emissivity variation of the thermocouples. For the equation methods by De, the correction accuracy is poor for the low speed flow and good for the high speed flow. However, the correction accuracy for the high speed flow is weakened if the emissivity of the thermocouples have large difference. For the equation method by Brohez, the overall correction accuracy is good but the accuracy degrades greatly with the large emissivity difference of the thermocouples.

Authors: Wang Lin , Kong Xiang , Zhang Xiang
Published: March 2023

In the process of urban construction and development, there are more and more construction projects such as building houses and planting trees, digging ditches, building Bridges and paving roads. The number of large-scale mechanical operations around the transmission lines continues to rise, which not only increases the pressure of channel operation and maintenance, but also hinders the stable operation of the power system. In order to further improve the quality and efficiency of the operation and maintenance of overhead transmission lines, some scholars proposed to continuously promote the operation and inspection business of transmission lines and create a new operation and inspection mode based on the concept of visual management, which can not only change the traditional work mode, but also solve the problems existing in the conventional operation and inspection. On the basis of understanding the problems facing the overhead transmission line inspection work, this paper focuses on the main content of practical work by determining the transportation inspection platform system architecture with visual management concept as the core, and discusses the application effect of the new transportation inspection mode of overhead transmission line with visual management as the core combined with experimental cases.

Effect of Melt Holding Time on the As-cast Microstructure and Hardness of Aluminum Alloy 2618
Authors: Chen Shanshan , Chai Zhizhang , Huang Zicheng
Published: March 2023

The effects of the melt holding time on the type, quantity and morphological distribution of aluminum alloy 2618 were investigated by means of OM, XRD and SEM. And the influence of the melt holding time on the hardness of alloy was explored. The results show that the heredity of the microstructure of the master alloy is not completely eliminated when the melt holding time is less than 10 min at 740 ℃. And it will make Al9FeNi phase coarse needle-like, and segregate with Al7Cu2Fe phase at the grain boundary or inside the grain. Properly prolonging the melt holding time can change the shape of Al9FeNi phase from coarse needle-like to fine needle-like and make the distribution of Al9FeNi phase and Al7Cu2Fe phase more uniform. Aluminum alloy 2618 was melted at 740 ℃ for 30 min and then poured into graphite molds at room temperature, which can make Al9FeNi phase fine and uniformly distributed in the matrix. With the extension of the melt holding time, the size of the nonequilibrium crystalline phase is basically unchanged, but the grain size will be slightly coarsened. The hardness of the alloy showed a trend of first increasing and then decreasing with the prolongation of the melt holing time within 10~60min, and when the melt was held for 30min, the hardness of the alloy reached the maximum HRB value of Rockwell hardness within the range of this test. The maximum value is 48.62HRB, and the hardness distribution of the alloy is relatively uniform. Therefore, it is beneficial to refine the precipitated phase, reduce the macro segregation, and refine the grain and improve the hardness of the alloy, while alloy 2618 was poured into the graphite casting at room temperature with melting at 740℃ and held for 30min.

Published: March 2023

SiC single crystal is a good semiconductor material with high breakdown electric field strength, high thermal conductivity, high carrier saturation drift speed and low relative dielectric. However, SiC has high hardness and brittleness, high chemical stability, so the polishing efficiency of existing polishing methods is low. In this paper, a plasma enhanced electrochemical mechanical polishing method for SiC was proposed. The relationship between peak voltage, frequency and duty ratio with polishing efficiency and surface roughness was studied.

The tropical coastal region of Malaysia has a hot climate, high average annual temperature, and varying quality of local raw materials, making it challenging and difficult to carry out large volume concrete projects in this region. In this paper, we developed a special admixture for bulk concrete in subtropical coastal environment by modifying the basis of acrylic acid-based polycarboxylic acid admixture. The concrete prepared with this admixture has good ease, no water secretion, excellent mechanical properties and greatly improved exothermic characteristics. The C50 mass concrete prepared with this admixture has an initial slump/extension of 220/585mm, a 2h slump/extension of 210/570mm, and a crack resistance class I.
