Manfredo Tafuri
Authors: Fiori Arantes Otília Beatriz
Published: July 2021

Foram escolhidas, dentre as várias falas, aulas e entrevistas de Otília Arantes, dedicadas a Manfredo Tafuri, duas palestras, pronunciadas em dois eventos acadêmicos da USP: a primeira, de 1994, uma homenagem de Otília ao arquiteto, historiador e crítico, logo após sua morte, num seminário sobre História da Cidade no campus de São Carlos, e a segunda, vinte anos depois, proferida num seminário internacional, “Manfredo Tafuri, seus leitores e suas leituras”, na FAU (fevereiro de 2015). Ambas tomando como foco principal seu livro Progetto e Utopia: Architettura e Sviluppo Capitalistico. A primeira, “A Arquitetura da Cidade: um ponto de vista”, após situar o Autor no contexto dos estudos sobre Arquitetura e Urbanismo na Itália dos anos 1960/70, procede a uma minuciosa análise de texto do livro citado, especialmente no seu diagnóstico sobre o esgotamento do Movimento Moderno, cada vez mais profundamente ligado, segundo Tafuri, à cidade como estrutura produtiva, portanto, reduzido a “mecanismo operativo” e, sua “ideologia do plano”, a uma “utopia regressiva”. Seguem-se algumas considerações sobre as manifestações posteriores, ditas pós-modernas, cuja crítica leva Tafuri a propor, como alternativa ao historicismo dominante, um “niilismo compiuto”. A interpretação deste último conceito, tomado naquele momento como expressão de um certo “pessimismo paralisante”, é retomada, passadas duas décadas, ao final da segunda exposição, mas já numa leitura que a própria Otília considera mais justa, interpretando-a como consequência natural de uma “filosofia da negação”. Este, aliás, o tema da conferência: “A dialética negativa de Manfredo Tafuri”, em que a Autora procura reconstituir,  em diálogo com Asor Rosa, as raízes marxistas de Tafuri, seu ponto de vista dialético, apenas sugerido na primeira fala, ou melhor, sua inserção na tradição marxista italiana, temperada, ao menos a partir de um certo momento, pela influência de um pensamento que começava a se difundir na Itália à época, ao menos no meio acadêmico italiano (anos 1960/70): a Teoria Crítica da Escola de Frankfurt – sem desprezar outras referências que compõem o que ela chama de “marxismo heterodoxo” ou de “saudável ecletismo” do pensamento  “nada linear” de Tafuri.

A magyarországi tejpiac értékesítési árainak alakulása 2003 és 2017 között
Authors: Szántó László , Szenderák János , Popovics Péter András
Published: July 2021

A nyerstej árak variációs koefficiense alapján az elemzett időszakok nagyobb részében erős ingadozás volt megfigyelhető. A nemzetközi árak tekintetében, a gazdasági világválság időszakában (2008/2009) valamennyi piacon mérhető volt a tejárak jelentős ingadozása, jellemzően 11 és 16% között. Ezt követően mérséklődtek, stabilizálódtak az árak, viszont 2015 és 2017 között ismét 10-14% közötti értékre emelkedtek. Az olaszországi termelői tejárakban nem voltak megfigyelhetők olyan ingadozások, mint az elemzett tagországok értékeiben. Magyarországi szinten vizsgálva a termelői, valamint a fogyasztói árakat, megfigyelhető, hogy a kereskedelmi árak stabilabbak, mint a termelők által kapott nyerstej ár. Ennek két lehetséges oka, hogy egyrészt a kereskedőknek nem érdeke a hirtelen árváltoztatás, mivel az az erősen árérzékeny fogyasztók elvesztését jelentheti. Továbbá a nyersanyagok (nyerstej) hagyományosan jobban ki vannak téve az áringadozás hatásainak, mint a fogyasztói árak. Kizárólag a 2012-2014-es időszakban mutatott hasonló értéket a variációs koefficiens, a többi időszakban a fogyasztói ár ingadozása mindig magasabb volt. Az árarányok vizsgálata során arra jutottunk, hogy a magyarországi árak együtt mozogtak mind a németországi, mind az olaszországi árakkal. Reáláron hasonló képet, de eltérő értékeket kaptunk az elemzés által. A kiinduló 0,04 és 0,27 értékű – 2003-2004-es – korrelációs együttható az elemzett időszak végére elérte az olaszországi és németországi 0,84-es és 0,60-as értéket, amely már egy sokkal szorosabb együttmozgást feltételezett a nyerstejárakban. Az eredmények alátámasztják azt, hogy a magyarországi tejpiac esetében is szorosabb lett az integráció a nemzetközi tejpiaccal. Továbbá a nyerstej árak volatilitása magas, hiszen az elemzett öt időszakból három esetben is 10% fölötti volt a variációs koefficiens értéke. A tejpiac integrációja azt feltételezi, hogy a termelők versenyképesebb helyzetbe kerülnek a következő években. Kiemelt szükség lenne a termelési költségek csökkentésére, mivel az árképzés folyamata nem veszi figyelembe a termelők egyéni termelési költségét. A tejpiaci védőháló fokozása is szükséges ebben az esetben. Látható, hogy a hirtelen vagy váratlan piaci gazdasági események hatása tartós maradhat. A gyenge tejpiaccal rendelkező tagállamok ez esetben szerkezetileg meggyengülnek. Az árak tekintetében várható a további tejpiaci integráció a világpiaccal, ezért a nemzetközi piacról érkező sokkhatásoknak kiemelt szerepe lesz az áralakításban.
IMPACTO DA DESAPROPRIAÇÃO DE IMÓVEIS NO PRAZO DE OBRAS DE IMPLANTAÇÃO RODOVIÁRIA NO ESTADO DO CEARÁ
Authors: Rabelo Antonio Nobre , de Farias Lucas Menezes , Lima João Henrique Camelo , Marinho Jefferson Luiz Alves
Published: July 2021

Os traçados rodoviários nem sempre podem ser implantados sem interferir com os imóveis existentes ao longo dos traçados projetados, sejam terrenos ou edificações, resultando na necessidade de desapropriações, as quais, além de onerarem o erário, impactam negativamente no prazo de entrega das obras à sociedade, em decorrência da morosidade do processo expropriatório. Este trabalho aborda a investigação das causas dessa morosidade, no âmbito das obras do Programa Rodoviário Ceará III, executado pelo DER (Departamento Estadual de Rodovias), hoje SOP (Superintendência de Obras Públicas do Estado do Ceará), o qual teve como principal objetivo melhorar a integração física das diversas regiões do estado do Ceará. Para a realização deste trabalho foi feita uma pesquisa exploratória junto à GEFAD – Gerência de Faixa de Domínio e Avaliação de Imóveis, do DER/CE, hoje DIRAE (Diretoria de Infraestrutura Rodoviária e Aeroportuária), na busca dos principais dados relativos ao andamento dos processos de desapropriação de imóveis de quatro segmentos rodoviários, no âmbito daquele programa, que permitissem estabelecer sugestões que contribuíssem com a melhoria da agilidade do processo de desapropriação de imóveis interferentes com seus respectivos traçados. Após a tabulação e análise dos dados sobre a desapropriação de quatro trechos, eleitos aleatoriamente para o estudo, verificou-se que o prazo de conclusão das quatro obras analisadas foi acrescido em nove meses, em média, tendo em vista a alteração do prazo médio de 12,5 para 21,5 meses, com relação ao prazo inicial. Dessa forma, o estudo realizado concluiu que a morosidade do processo de desapropriação deve-se, principalmente, ao atraso na elaboração dos laudos de avaliação dos imóveis e à demora da PGE/CE (Procuradoria Geral do Estado do Ceará), para aprovação do processo indenizatório dos imóveis, ficando evidente a necessidade do melhor planejamento das ações relativas à implantação de rodovias, com vistas à abreviação da entrega dessas importantes obras à sociedade cearense.

La Procuración General de la Nación (PGN) en Argentina y la Fiscalía General de la Nación en Uruguay (FGN): una mirada sociológica y comparativa sobre dos gestiones
Authors: Guthmann Yanina
Published: July 2021

En el marco de los estudios sociales sobre la justicia y el derecho, este artículo se centra en el área ejecutiva de los organismos que nuclean a los fiscales en Argentina y Uruguay, la Procuración General de la Nación (PGN) y la Fiscalía General de la Nación (FGN), respectivamente. Se estudian en particular dos gestiones consideradas paradigmáticas en términos de reforma institucional: la de la procuradora argentina Alejandra Gils Carbó (2012-2017) y la del fiscal general uruguayo Jorge Díaz (2012-actualidad). El objetivo de este trabajo es brindar algunas herramientas conceptuales para pensar sociológicamente las políticas públicas de justicia. La metodología elegida es cualitativa: realización de entrevistas, análisis de documentos y fuentes secundarias. La perspectiva comparativa permite contextualizar la importancia de los cambios institucionales propuestos por estas gestiones. Más allá de un paradigma común en la región, favorable a la necesidad de cambios en el sistema de administración de la justicia en general, el resultado de la investigación muestra algunas divergencias en aspectos claves de las reformas en cada país que pueden llevar a indagar la dimensión cultural que subyace al quehacer y pensar judicial.
Development of a high-power EUV irradiation tool in a hydrogen atmosphere
Authors: Harada Tetsuo , Yamakawa Shinji , Toyoda Mitsunori , Watanabe Takeo
Published: July 2021

Extreme ultraviolet (EUV) lithography has recently been utilized as a high-volume manufacturing technology for advanced semiconductors. An EUV mirror can be easily contaminated in the existence of a residual hydrocarbon vapor gas inside an exposure chamber in a vacuum environment, which reduces the reflectance of the Mo/Si multilayer coating. To reduce this carbon contamination, hydrogen gas is introduced at a pressure of a few pascals in the EUV scanner. However, during this process, the multilayer may be damaged by hydrogen. In addition, the multilayer surface can become oxidized by residual water vapor in the vacuum chamber. Therefore, an EUV irradiation tool in hydrogen and water vapor atmospheres was developed and installed at BL-09 of the NewSUBARU synchrotron light facility to evaluate the cleaning effect and irradiation durability of the Mo/Si multilayer. The EUV irradiation intensity increased up to 6 W cm−2, and the hydrogen pressure reached 70 Pa.
Criteria for the Classification of Legal Systems
Authors: Zernov A. O. , Voskresenskaya E. V. , Zhil’skiy N. N.
Published: July 2021

The article considers the necessity and importance of the issue concerning the classification of legal systems, which is caused by the following. The idea of classification of legal systems arose in comparative law at the beginning of the XX century in connection with the increase in national legal systems; with the destruction of the colonial system, the legal systems of the liberated countries arose and developed; and at the end of the XX century, this trend continues with the destruction of the socialist political system, which entails the appearance of new legal systems on the legal map of the world. It is also necessary not only to study it from the point of view of the special, consideration of individual parts that incorporate similar legal systems, but also to solve the problem in practice-the unification of current legislation and the improvement of national legal systems.
Protection of Russian Citizens Living and Working Abroad: Juridical Aspects
Authors: Mikhailov V. V.
Published: July 2021

The article is devoted to the problem of protection of Russian citizens living and working in foreign countries, which is relevant in modern Russian jurisprudence. The deterioration of the international situation makes this topic even more relevant, since the rights of Russian citizens abroad are increasingly violated, and existing bilateral agreements are not being implemented. It is proposed to consider the problem of Russian citizens abroad in the complex of protection of group rights, which requires clarifying the concept of group rights, including categories of groups of citizens living in foreign countries, determining the legal status and characteristics of these groups. The creation of a single legal space for individual and group rights should create conditions for the activation of the state and the public’s activities for the legal protection of Russian citizens abroad, and support the cultural and economic ties of Russian diasporas with Russia.

Implementation of a GNU Radio Based Search and Rescue Receiver on ESA’s OPS-SAT Space Lab
Authors: Mladenov Tom , Evans David , Zelenevskiy Vladimir
Published: July 2021

OPS-SAT is the first publicly accessible Hardware/Software innovation Lab in Low Earth Orbit. It was launched by the European Space Agency (ESA) on December 18th 2019 and is open to European academia and industry allowing new concepts to be tested in space with a range of interesting payloads. This paper discusses the implementation and results of an In-orbit Demonstration (IOD) using the Software Defined Radio (SDR) payload of OPS-SAT together with on-board RF Processing techniques. We demonstrate the design of a software configurable Search and Rescue receiver using GNU Radio, running on Linux in a 3U CubeSat. The system runs on the Satellite Experimental Processing Platform (SEPP) Cyclone V ARM System-on-chip and is able to autonomously detect and decode transmissions from terrestrial 406 MHz beacons from the global COSPAS-SARSAT search and rescue system. Decoded beacon information is logged on-board together with metadata and is downloaded to Mission Control at ESA/ESOC. The successful IOD paves the way for in-orbit RF experimentation and bridges the gap between satellite operations and the IoT era.
Elastic O-RAN Slicing for Industrial Monitoring and Control: A Distributed Matching Game and Deep Reinforcement Learning Approach
Authors: Abedin Sarder Fakhrul , Mahmood Aamir , Tran Nguyen H. , Han Zhu , Gidlund Mikael
Published: July 2021

In this work, we design an elastic open radio access network (O-RAN) slicing for the industrial Internet of things (IIoT). Unlike IoT, IIoT poses additional challenges such as severe communication environment, network-slice resource demand variations, and on-time information update from the IIoT devices during industrial production. First, we formulate the O-RAN slicing problem for on-time industrial monitoring and control where the objective is to minimize the cost of fresh information updates (i.e., age of information (AoI)) from the IIoT devices (i.e., sensors) while maintaining the energy consumption of those devices with the energy constraint as well as O-RAN slice isolation constraints. Second, we propose the intelligent ORAN framework based on game theory and machine learning to mitigate the problem’s complexity. We propose a two-sided distributed matching game in the O-RAN control layer that captures the IIoT channel characteristics and the IIoT service priorities to create IIoT device and small cell base station (SBS) preference lists. We then employ an actor-critic model with a deep deterministic policy gradient (DDPG) in the O-RAN service management layer to solve the resource allocation problem for optimizing the network slice configuration policy under time varying slicing demand. While the matching game helps the actor-critic model, the DDPG enforces the long-term policy-based guidance for resource allocation that reflects the trends of all IIoT devices and SBSs satisfactions with the assignment. Finally, the simulation results show that the proposed solution enhances the performance gain for the IIoT services by serving an average of 50% and 43.64% more IIoT devices than the baseline approaches.
A Constrained Many-objective Optimization Evolutionary Algorithm with Enhanced Mating and Environmental Selections
Authors: Ming Fei
Published: July 2021

Unlike the considerable research on solving many objective optimization problems with evolutionary algorithms, there has been much less research on constrained many-objective optimization problems (CMaOPs). Generally, to effectively solve CMaOPs, an algorithm needs to balance feasibility, convergence, and diversity simultaneously. It is essential for handling CMaOPs yet most of the existing research encounters difficulties. This paper proposes a novel constrained many-objective optimization evolutionary algorithm with enhanced mating and environmental selections, namely CMME. The main features are: i) two ranking strategies are proposed and applied in the mating and environmental selections to enrich feasibility and convergence; ii) an individual density estimation is designed, and crowding distance is integrated to promote diversity; and iii) the ?-dominance is used to strengthen the selection pressure on both the convergence and diversity. The synergy of these components can achieve the goal of balancing feasibility, convergence, and diversity for solving CMaOPs. The proposed CMME algorithm is evaluated on 10 CMaOPs with different features and a variable number of objective functions. Experimental results on three benchmark CMOPs and three real-world applications demonstrate that CMME shows superiority or competitiveness over nine related algorithms.
An Unsupervised Deep Unfolding Framework for Robust Symbol Level Precoding
Authors: Mohammad Abdullahi , Masouros Christos , Andreopoulos Yiannis
Published: July 2021

Symbol Level Precoding (SLP) has attracted significant research interest due to its ability to exploit interference for energy-efficient transmission. This paper proposes an unsupervised deep neural network (DNN) based SLP framework. Instead
of naively training a DNN architecture for SLP without considering the specifics of the optimization objective of the SLP domain, our proposal unfolds a
power minimization SLP formulation based on the
interior point method (IPM) proximal ‘log’ barrier
function. Furthermore, we extend our proposal to a
robust precoding design under channel state information (CSI) uncertainty. The results show that our proposed learning framework provides near-optimal performance while reducing the computational cost from O(n7.5) to O(n3
) for the symmetrical system case where
n = number of transmit antennas = number of users.
This significant complexity reduction is also reflected
in a proportional decrease in the proposed approach’s
execution time compared to the SLP optimization-based solution.
LiDAR Integrated High-Capacity IR OWC System with Abilities of Localization and Link Alignment
Authors: Li Zhi
Published: July 2021

By using narrow infrared (IR) beams, optical wireless communication (OWC) system can realize ultra-high capacity and high-privacy transmission. However, due to the point-to-point connection approach, a high-accuracy localization system and beam-steering antenna (BSA) are required to steer the signal beam to user terminals. In addition, to achieve link alignment in the receiver, the BSA needs to be within the limited receiver field of view (FoV). This problem greatly limits the practical application of high-capacity IR optical wireless communication and has not been well solved yet. In this paper, we proposed an indoor beam-steering IR OWC system with high-accuracy and calibration-free localization ability by employing a coaxial frequency modulated continuous wave (FMCW) light detection and ranging (LiDAR) system. In the meantime, benefit from the mm-level ranging accuracy of the LiDAR system, a feasible approach to deal with the link alignment issue for practical applications is firstly demonstrated. With the assistance of the LiDAR system, we experimentally achieved the localization of user terminals with a 0.038-degree localization accuracy, link alignment at the receiver and an error-free on-off keying (OOK) downlink transmission of 20 Gb/s in free space at 3-m distance is demonstrated.
Variable-Temperature Noise Characterization of N-MOSFETs Using an In-Situ Broadband Amplifier
Authors: Ohmori Kenji , Amakawa Shuhei
Published: July 2021

Characterization of broadband noise of MOSFETs from room temperature down to 120 K in fine temperature steps is presented. A MOSFET is mounted on a reusable printed circuit board vehicle with a built-in low-noise amplifier, and the vehicle is loaded into a cryogenic chamber. The vehicle allows noise measurement in the frequency range from 50 kHz to 100 MHz. At low frequencies, it enables extraction of activation energies associated with electron trapping sites. At high frequencies, as has been suggested by noise figure measurements, the white noise of MOSFETs is shown to be dominated by the shot noise, which has much weaker temperature dependence than the thermal noise. The shot noise will a problematic noise source in broadband RF CMOS circuits operating at cryogenic temperatures.
La formazione incorporata nei contesti lavorativi

Published: July 2021

Learning devices can be embedded into organizational contexts. Through them learning processes can be intentionally activated as to transform employees while working. Workplaces have their own learning potential due to their high level of structuring and regulation. Their learning potential transform organizational actors while they are in the productive actions. Identifying embedded learning processes helps in intercepting learning valencies of workplace experiences and observing learning actions that can lead to transformative processes. Results of related research activities are presented in the volume. They have been carried out in more than ten years of research implemented in three types of organisations: business, museum, prison. Research experiences are analysed by using a model of study that is based on the reconstruction of the learning processes as they are experienced by the actors considered. Moreover the model is based on the analysis of learning actions that are embedded into the productive and service provision processes. Factors and conditions are analysed as well through which organisations can act on employees transformation.
A Comparative Analysis of the Pronunciation of Engineers and Bureaucrats: An Explanatory Research
Authors: Afshan  , Dr. Sikandar Ali  , Anum Saeed
Published: July 2021

It is a fact that English has become part and parcel of our society. All the fields of our society have been affected by English in the modern epoch. Major important issues pertaining to English language teaching are still unanswered because of lack of strategy for teaching English in our educational institutes. Similarly, pronunciation is one of the major factors, which ruins the image of a speaker, although he or she is good in grammatical and other features of English language. The purpose of instant study is to find out the reasons behind mispronunciation of English language in our society. For this purpose, two types of important professional fields of our society were taken up for experiment, which were bureaucrat and engineer. Similarly, two types of research tools were adopted, first was an Observation Sheet and second was structured open-ended questionnaire. The results show different aspects of both targeted groups. It was revealed by the research that bureaucrats are in favour of going with correct pronunciation, whereas engineers are not as enthusiastic to be corrected in pronunciation as bureaucrats.

Published: July 2021

Esse trabalho propõe uma reflexão das narrativas de três pesquisadores que relatam sobre os seus processos criativos no período do distanciamento social causado pela Covid-19. O objetivo foi perceber os processos de subjetividade que podem impactar na elaboração da pesquisa acadêmica no período da pandemia. De modo a identificar as práticas, as experiências e a construção do sujeito – pesquisador. Metodologicamente, é um estudo de abordagem qualitativa a partir da relação entre as entrevistas narrativas do método (auto)biográfico e o referencial teórico. Evidenciamos por meio desse estudo que a construção de uma subjetividade perpassa pela influência do meio social em um tempo de lutas e de incertezas no contexto político. Nos processos de investigação acadêmica, o sujeito-pesquisador é atravessado por uma subjetividade nas suas produções e se vê desafiado a utilizar de sua criatividade para o fazer científico. Os elementos que orientam as reflexões aqui desenvolvidas destacam-se: o reconhecimento de técnicas de resistência do sujeito, o ato de narrar como ponto de encontro da sua transformação e a produção de si e dos processos criativos.

In this study, hydrothermal treatments (duration: 2 h, 5 h, 8 h; temperature: 60°C, 80°C, 100°C), ultrasonic treatments (duration: 60 min, 90 min, 120 min; temperature: 40°C, 50°C, 60°C; ultrasonic power: 400 W, 600 W, 800 W) and freeze-drying treatments
(vacuum degree: 0.05 mbar, 0.1 mbar, 0.5 mbar, 1.0 mbar, 1.7 mbar) were performed respectively to improve the permeability of glue-laminated bamboo. The effects of different pre-treatments on the permeability were compared according to the water absorption test and the mercury intrusion porosimetry test. The microstructure change of the samples was observed by scanning electron microscope (SEM). The results showed that freeze-drying treatment was an effective way to increase the permeability of the samples, in which the water absorption rate can be increased by 47%, and the porosity can be increased by 10% at 0.5 mbar vacuum. From SEM analysis, some small holes appeared in the cell wall of the freeze-dried samples, because he free water inside the samples was changed into ice, and the volume became larger, and the pore diameter of the bamboo was enlarged.

This study was carried out to determine the effects of bleaching chemicals and
varnishes on the amount of carbon dioxide (CO2) in the combustion of oriental beech
(Fagus orientalis Lipsky). For this purpose, samples of Oriental beech prepared according to ASTM D 358 contain 18% R1 = (NaOH + H2O2), R2 = (NaOH + Ca(OH)2 + H2O2), R3 = (Na2S2O5 + H2C2O4), R4 = (NaSiO3 + H2O2), R5 = (KMnO4 + Na2S2O5 + H2O2) solution groups, after bleaching with solution groups, water based, synthetic, polyurethane and acrylic varnish were applied according to ASTM D 3023 and combustion tests were carried out in accordance with ASTM E 160-50. Gas measurements were made with the SIGMA 74172 NSU flue gas device during the combustion process. As a result, in respect to the burning types; the highest amount of CO2 (ppm) was found in the self-combustion (8.468 ppm) while the lowest was obtained from the flame combustion source (4.599 ppm). In respect to the types
of bleaching; the highest in R5 (7.458 ppm) and the lowest in R3 (4.059 ppm) were found. According to the varnish types; the highest value was found in the synthetic varnish (8.261), and the lowest value was found in the acrylic varnish (4.772 ppm). According to combustion type + bleaching solution + varnish type interaction, the highest values were found for without flame combustion (II) + R3 + Sn (18.40 ppm) and lowest for flame source combustion (I) + R5 + Pu (0.600 ppm). Consequently, the highest values for combustion gases were found in samples of oriental beech wood samples treated with water-based varnish with R1 solution. According to this, in terms of human health and life safety, possibility of fire in places, R3 solution and acrylic varnish may be used in the related industries.

This study aims at investigating the effect of three altitude levels (below 1800 m, 1800-2000 m and above 2000 m) on the physical and biometric properties of stem-wood and branch-wood of hawthorn species. Moreover, the relationship between wood dry density and volumetric swelling, fiber length, fiber diameter, cell wall thickness were studied. Results indicated that altitude had significant effects on the dry density, volumetric swelling and fiber length of stem wood while did not significant effects on the density of branch wood. Additionally, some physical and biometric properties had relatively greater correlation coefficients in branch wood than in stem wood whereas others had higher coefficients in stem wood compared to branch wood. Deep understanding of properties this wood species will provide a fresh insight into the relationship between wood properties and environmental factors.

For use as decoration panels, wood fiber was used to prepare a new type of aromatic fiberboard using hot-press technology that mixes spices and adhesives. Experiments showed that the use of different proportions of two kinds of spices, wormwood and lavender, mixed with waterborne acrylic adhesives, had a slight influence on the curing time and viscosity of the glue. The different mixtures equally affected the physical and mechanical properties of the fiberboard and the smells similarly affected brain wave frequencies. The experimental results showed that a 20% proportion of lavender and wormwood was optimal compared with 5%, 10%, and 15%, and this amount also provided the best health-care effect. This work provides the experimental data and a theoretical basis to achieve pharmacological and health-care effects for the development of aromatic and other special kinds of fiberboard for industrial applications.

To compare the wood quality of Dahurian larch and Japanese larch growing in Korea,
the physical and mechanical properties were examined using the Korean standards.
The proportion of heartwood was 82% and 72% in Dahurian and Japanese larch, respectively. The percentage of latewood was 42% in Dahurian larch and 35% in Japanese larch. The growth ring width of Dahurian larch was narrower than that of Japanese larch. Dahurian larch showed about 20% higher green moisture content compare to Japanese larch wood. Density and shrinkage of Dahurian larch were higher than Japanese larch. Axial compression strength, young`s modulus in compression, and shearing strength in heartwood of Dahurian larch were 11 MPa, 686 MPa, and 2.3 MPa, respectively, showing higher value than Japanese larch. The hardness was in the range of 13.8–38.7 MPa in Dahurian larch and 17.7–48.4 MPa in Japanese larch. The compression strength parallel to the grain and shearing strength in both species were significantly correlated with oven-dried density. Besides, the hardness in Dahurian larch was significantly correlated with latewood percentage and oven-dried density.
In conclusion, the differences in the properties of both species were revealed and the results can be used for quality indices of both wood species.

Published: July 2021

A novel structural member, the bamboo plywood-encased thin-walled steel tube/stone dust concrete composite column (BSDCC), was investigated in this study. Axial compression tests were conducted on 10 BSDCC specimens; their failure characteristics and modes were examined, and the effects of the stone-dust concrete content ratio and strength, specimen slenderness ratio, cross-sectional composition and binding bar confinement pattern, and binding bar spacing ratio on the bearing capacity and deformation of the columns were investigated. Two main compressive failure modes were observed: (1) adhesive failure by cracking and debonding between the bamboo plywood boards and between the bamboo plywood and the steel tube and (2) compressive-flexural failure of the bamboo plywood between the binding bars in the middle of the specimen. For specimens with the same cross-sectional dimensions, the cross-sectional content ratio of the stone dust concrete impacted the deformation and failure mode but did not significantly affect the ultimate bearing capacity. The bearing capacity decreased with increasing specimen slenderness and binding bar spacing ratio and increased with increasing stone dust concrete strength and bamboo plywood constraint (in terms of the cross-sectional composition and binding bar restraint pattern). A model for the ultimate bearing capacity of BSDCCs was established through regression analysis.

SCP adalah Make To Order. Produksi briket tidak terlepas dari masalah yang berkaitan dengan tidak seimbangnya aliran produksi. Pada aliran produksi briket PT. Saraswati Coconut Product terdapat antrian material yang menghambat aliran produksi hingga terjadi bottleneck. Akibatnya proses produksi briket arang menjadi lebih lama dari waktu normal produksi. Untuk mengetahui penyebab permasalahan bottleneck  secara detail, maka perlu dilakukannya identifikasi penyebab masalah dari sistem produksi briket dengan menggunakan metode diagram  fishbone (tulang ikan). Diagram fishbone (Diagram Tulang Ikan) adalah diagram sebab akibat yang dapat digunakan untuk mengidentifikasi potensi masalah kinerja. Diagram tulang ikan menyediakan struktur untuk diskusi kelompok sekitar potensi penyebab masalah tersebut.  Tujuan dari analisa ini mengetahui penyebab bottleneck dan tindakan perbaikannya. Hasil observasi lapangan dapat diketahui bahwa penumpukkan material (bottleneck) terjadi pada jalur aliran bahan stasiun pretel dan stasiun drying. Penumpukkan material terjadi karena hasil cetakan briket dari stasiun pretel harus menunggu terlebih dahulu sebelum melalui proses pengeringan pada oven. Adapun rata-rata waktu proses oven untuk mengeringkan briket dari tujuh (7) oven yang ada di stasiun drying adalah 66 jam. Waktu proses ini melebihi dari waktu proses stasiun kerja lain yang hanya membutuhkan waktu proses kurang dari 24 jam.Kata Kunci : aliran produksi, bottleneck, diagram fishbone,
Realisticity of Individual Choice Model Does Matter: On Cartel Prosecution
Authors: Shastitko A. Ye. , Dozmarov K. V.
Published: July 2021

Criminal prosecution of monopolistic activities in the form of market cartelization is the most sensitive tool for individuals, which can have both a serious deterrent effect and limit behavior that is beneficial to public welfare. This paper discusses the theoretical aspects of the issue of choosing a regime of antitrust enforcement in connection with the design of amendments and enforcement of the norms of Article 178 of the Criminal Code of the Russian Federation, taking into account possible differences between the initialization, conclusion of a cartel agreement and participation in it. The article shows that there are various options for the relationship between the concept of conclusion and participation in the agreement, including anti-competitive one. However, this requires the application of realistic assumptions regarding the behavior of individuals. Practical issues of designing criminal penalties for cartels are considered taking into account various legal concepts, including the form and types of guilt, as well as on the basis of a comparison with other articles of the Criminal Code that punish collective unlawful acts. In connection with the problem of reproduction of an inhospitable tradition, the Russian antitrust identified the risks of imputed imputation (risks of I type errors) and insufficient punishment of the cartel organizer (risks of II type errors) in case of underestimating the importance of economic concepts based on the principle of methodological individualism and the assumption of bounded rationality of individuals.
