Published: February 2021

Os atuais padrões de consumo e produção têm trazidos impactos diversos à qualidade do meio ambiente, sendo que um dos principais problemas é a geração exacerbada de resíduos sólidos. Devido ao seu intenso volume, os resíduos sólidos urbanos constituem-se um dos maiores desafios do Poder Público, além de que, inferem diretamente sobre a relação das pessoas com o consumo. Ante ao contexto apresentado, o objetivo deste trabalho é identificar a percepção ambiental dos moradores de dois bairros em um município do estado de Minas Gerais, quanto à situação vivenciada em relação à disposição de resíduos sólidos em lixeiras dispostas frente às suas casas, visando observar se tal situação se enquadra nos conceitos de injustiça ambiental. Como metodologia, utilizou-se de entrevistas semiestruturadas, as quais continham perguntas binárias e outras baseadas na escala Likert. Como resultados, obteve-se dados quanti e qualitativos, encontrando-se respostas variadas sobre a satisfação dos serviços de coleta e também sobre a percepção/entendimento acerca do tema. Conclui-se que a percepção varia expressivamente entre os moradores, bem como, há evidencias de injustiça ambiental entre os dois territórios estudados.

El cuerpo humano es nuestra forma de ser en el mundo. Requiere para poder ser y vivir en su ambiente, de réplicas representadas en la arquitectura, la ciudad y los objetos. El cuerpo está implicado, tanto en el yo, como en el ello, y se afirma en el ser individual y social para desarrollarse en el tiempo, Es de ésta forma, una construcción social e histórica. El cuerpo es materia de filosofía, de ciencia, de arte y de poesía. No se vive otra realidad diferente a la que procura el cuerpo y su visión de la realidad. El espacio se fenomeniza en el cuerpo, pero el cuerpo a su vez se espacializa. La arquitectura y la ciudad son meta-cuerpos, donde se encuentran la naturaleza, la interioridad humana y la exteriorización de sus dinámicas. El cuerpo mientras percibe el mundo crea a su vez un mundo. La mente, en principio no ponderable, se corporeiza para ser en el mundo.

Quality seed is one of the determining factors of successful agricultural cultivation. Seeds that have been stored for a long time will experience seed deterioration, which is characterized by a decrease in seed viability. Improving seed viability can be done by seed invigoration. One of the seed invigoration techniques is organic priming by using organic substances extracts that are rich in phytohormones such as auxin, cytokinin, and gibberellins. The purpose of Organic priming is to improve the seed physiological and biochemical condition that related to growing speed, growing simultaneity, and germination. Mung bean sprout extract can be used as an extract for organic priming because it is proven to contain phytohormones. This study aims to determine the interaction between varieties and concentrations of bean sprout extracts and the best combination of varieties and extract concentrations on the viability of rice seeds. The research was carried out in April - June 2020 at the Laboratory of Agricultura Biology, Agriculture Faculty, Lambung Mangkurat University. The experiment  was arranged based on Factorial Randomized Block Design (RBD) 4x6 with Three replications. The variables observed were seeds germination, simultaneity of seedlings growth and speed of seedlings growth. The results showed that the interaction factor between varieties and concentration had a very significant effect on increasing seed viability and the best combination was found in Baroma varieties with concentrations of 20 % and if concentrations higher or lower than 20 % performance of rice seed viability will decrease. The highest percentage of seed germination was found in Baroma varieties with a concentration of 20 % (v4k3), which is 82.67 % not significantly different from Baroma varieties with a concentration of 10 % (v4k2) and INPARA 3 varieties with a concentration of 20 % (v1k3). The highest percentage of simultaneity of seed growth was found in Baroma varieties with a concentration of 20 % (v4k3), which is 81.50 % not significantly different from Baroma varieties with a concentration of 10 % (v4k2), Mutant line No. 14 with a concentration of 20 % (v3k3), and INPARA 3 variety with a concentration of 20 % (v1k3), while the fastest percentage of seed growth rate is in Baroma with a concentration of 20 % (v4k3), which is 29.50% significantly different from all varieties and other bean sprout extract concentrations.

Among various bioremediation methods, bioaugmentation is the one which frequently used. In this study, bioaugmentation was conducted by utilising Pseudomonas aeruginosa, Bacillus cereus, and Brevibacterium flavum. Many studies on and implementations of this method have been conducted. However, this method still needed to be studied especially with reference to its implementations to small automotive workshops, which their number was increasing, as the sources of the soil contamination. The objective of this study was to identify the most effective bacteria in removing total hydrocarbon content (TPH) from contaminated soils and to understanding several characteristics of the method. Laboratory research was set up and the experimental design was complete randomised design (CRD) with three replications. Statistical test of Anova with α 5% was carried out to evaluate the results of the study. The treatments of this study were three species of bacteria which were inoculated separately into the contaminated soils. The parameters were TPH, pH and the density of bacteria consortiums. The highest effective removal of TPH was showed by P. aeruginosa, 64,1% (δ+2,61%), followed by B. flavum and B cereus. This treatment had pH dropped two points and the density of bacteria consortium increased 6-10 times. The main limitation of this study was the number of parameters which was a few resulting difficulties in understanding the hydrocarbon degradation processes.

Biopore infiltration hole are hole made for run-off flow which if allowed to cause erosion and can remove the topsoil, causing soil fertility to be reduced. The use of biopori infiltration holes can be maximized by adding organic matters into the hope that in addition to absorbing water it can increase soil fertility. The liquid waste of tofu and meranti litter is an organic matters are used in this study, by adding organic matters to the biopori hole. This study aims to look at the effect of providing organic matters in the biopore hole derived from tofu and litter liquid waste on the value of pH, C-Organic, and post-mining CEC. This study was an experimental study in the field using a completely randomized design of one factor, namely organic matters with six levels, namely without organic matters and using 25 g, 50 g, 75 g, and 100 gr organic matters given to the biopori hole in incubation for one month later Soil samples taken were analyzed for pH, C-organic, and CEC. The results showed that the treatment only affected the soil's pH value. Organic material provided in the biopori hole is thought to have not completely decomposed, causing the soil around the biopori infiltration hole to remain acidic. The acidity of the soil is due to the gases produced during the decomposition process. Changes in soil pH ranged from 4.36 to 4.65 by administering 75g of organic matters from tofu liquid waste and meranti litter. This research is useful in post-mining land reclamation in increasing soil fertility, with the improvement of soil chemical properties such as pH will slowly improve the physical and biological properties of the soil so that it can be used as cultivation land.
The Trans-Arctic in the Context of Russian Priorities
Authors: Labetskaya E.
Published: February 2021

In terms of the space concept, the prospects of Russia's new formats of global co-operation development through mutually beneficial transnational partnership in the Arctic are analyzed in the article. The possibility of implementation of Russia’s Eurasian and Arctic advantages in the Trans-Arctic as the key element of global connection between Trans-Atlantic and Trans-Pacific spaces is considered. Until now the "Eurasian dividends" for Russia have been associated with strengthening of its positions in the Pacific Asia. However, the scale of Russian socio-economic and naval presence in this area does not allow the country to become a leader. The situation is completely different in the Trans-Arctic, where Russia’s total capacity is equal to that of other Arctic states. Moreover, in the Trans-Arctic the "Eurasian factor" may become an "influence multiplier" for Russia. This refers to Russia’s key role in the connection between Trans-Atlantic and Trans-Pacific through the logistic chain: Northwest Passage – Northern sea route – Eastern Siberia’s river system – Trans-Siberian Railway. The Trans-Arctic may become a "testing ground" for neutralisation of attempts to isolate Russia from global governance, which appeared in G-8 dismantling. The initiation of a new structure with participation of global “extraregional” actors, first of all Russia's strategic BRICS partners, could become its efficient Arctic pivot. Special attention is paid to subjects of the multilevel governance over the Trans-Arctic, to aspects of connection between transnational spaces, to the potential conflictogenity of the Arctic macroregion, and to the problem of the sovereignty concept classical understanding transformation, which appeared in the Arctic context. The relevance of the topic stems from decisions of the RF Security Council special extended meeting (April 2014), which put the "qualitative strengthening" of Russian positions in the Arctic, "preservation of Russian influence" in the region, and "advancing of partners" as major priorities. The tendencies of the Arctic transnationalisation and of the Trans-Arctic formation indicate a serious challenge for the Russian expert community and policy-makers. On one hand, Russia cannot sacrifice its national interests and restrict its rights and powers in the areas, to which its sovereignty and jurisdiction extend. On the other hand, formation of a new global governance regime in the Arctic gives Russia a chance to strengthen its leadership in this polar area, since the socio-economic, political and reputation dividends brought by such regime might be extremely high.
Quarter-Century after “Velvet Revolution”: How Are You, Slovaks?
Authors: Korovitsyna N.
Published: February 2021

The article considers changes in most important areas of Slovak society after 1989: dynamics of social stratification, family values, religiosity, leisure activities, voting behavior and preferences, democratic participation. The aim is to examine the contemporary position of Slovakia between the East and the West European civilization systems after two waves of social transformation in the middle and at the end of the 20th century, considering the accelerated change of the underdeveloped agrarian social structure into the industrial type under the "real socialism". However, at the beginning of the 21st century Slovak settlements still retain a strong rural character. As a result of market reforms and westernization a large part of the countryside tremble in the balance, processes of depopulation and formation of excluded social groups take place especially in small municipalities. Further still, in the context of increasing migration from cities to countryside more and more rural patterns of thinking extend to urban environments. The primarily important urban-rural line of societal differentiation, perceptions, attitudes and voters decision-making process are analyzed on base of Slovak sociologists' research. They discovered the phenomenon of historic “embedding” of the party type gaining the voters' support and commitment to one-party system, starting from the Inter-War Period till present. Slovakia represents the case of the weak left-right party profiling and inclination to various “parties of collective identity”. Definitive significance of ethnicity and religion as divisions in mass political orientations, traditionally characterized by the emphasis on leftist orientations, social rights and value of nation are shown in the paper. According to results of the latest socio-empiric studies in the country, most people in Slovakia (mainly the so called “loosers”) did not adopt neoliberal, Western-type path of development, regarding the existing inequalities as too large, and preferring social equality in a society of poor to social differentiation in a society of abundance. Social rights are estimated by the majority of Slovak people higher than political rights now.

Published: February 2021

Keyhole laser beam welding (LBW) of stainless steel sheets with a gap in between is numerically simulated with a three-dimensional, transient multi-physical model for laser material processing. At first, the model’s ability to reproduce experimental results on a relatively coarse computational mesh within reasonable computing time, so as to serve as process optimization tool, is presented. An example of process optimization, where a given set of weld seam quality criteria is fulfilled by iteratively optimizing a secondary laser beam, is shown. The relatively coarse mesh, in combination with a good model calibration to the experimental conditions, allows for sufficiently fast simulations to use this approach for optimization tasks. Finally, using a finer spatial and temporal discretization, the dynamic processes in the vicinity of the keyhole leading to the formation of pores are investigated. The physical phenomena predicted by the simulation are coherent with experimental observations found in literature.

Frame-Assisted Reduction of a B-Type Pilon Fracture Dislocation: Talar Body Incarceration on an Intact Fibula
Authors: Campbell Sean T. , DeBaun Malcolm R. , Githens Michael F.
Published: February 2021

Case:

We describe an irreducible anterolateral tibiotalar dislocation with an AO/OTA (Arbeitsgemeinschaft fur Osteosynthesefragen/Orthopaedic Trauma Association) B-type pilon fracture. The injury was initially treated with closed reduction, using a medializing force achieved with an external fixator to unhinge the talar body from the fibula, followed by temporary stabilization. Definitive fixation was performed once the soft tissues had recovered.

Conclusion:

This unique irreducible pilon fracture dislocation pattern is important to recognize to prevent iatrogenic complications associated with multiple failed closed reduction attempts. Frame-assisted, percutaneous, or open maneuvers may be required to facilitate a reduction. Staged treatment with temporization in an external fixator may be required.
A Psychoanalytic Reading of Selected Persian Children’s Plays
Authors: Karimi Zeinab , Hadaegh Bahee
Published: February 2021

Once theatre aims at children, who are the citizens and decision makers of the future, it can influence the course of society through the values and worldviews that it promotes. The exceptional capacity of this medium in engaging the audience, along with children’s receptiveness, necessitates a meticulous study of the ideologies embedded in plays. This study unravels how these ideological factors can hamper the theatre’s main purpose which is to encourage the audience to form individual fantasies. Accordingly, Žižek’s theories are drawn upon for their hints on ideology, fantasy, reality, and subjectivity. Taking his psychoanalytic views into account, four Persian plays are examined to determine what ideologies underlie these plays’ motifs and instructions, as well as what may justify their presence in plays. On close inspection, it becomes evident that these plays are loaded with conscious manipulative ideologies which are intended to train homogeneous social members rather than present objective glimpses of real life.
The Combined Chemical and Mechanical Modifications of Cigarette: A Novel Methodology to Reduce Harmful Effects

Published: February 2021

Without hindering the taste, making a cigarette less harmful by reducing the percentage of toxic and carcinogenic compounds in the smoke of the cigarette is the challenging task for the current generation researchers. In the current work, by implementing mechanical and chemical modification techniques, the above stated is tried to mitigate. In addition to the above, the optimized suction pressure, burning time and the number of puffing are determined. Then, at the optimized conditions, the modifications are implemented. Mechanical modification technique considers filter to cigarette ratio and filter design. The mathematical calculation reveals that puffing stops when the cigarette length reaches 0.15 times of its original length. Furthermore, it also identified that the concentration of suspended solids and droplets in the smoke decreases significantly (separation efficiency = 56.81%) if the cigarette to filter ratio is 2.32. In the case of chemical modification, various adsorbents such as charcoal and Zeolite 13X used to reduce the harmful effect in the output. These processes depict reduction in harmful effect (separation efficiency up to 62.1%) by showing decrement in the suspended solids and droplets in the smoke due to the adsorption on the active sites of charcoal and Zeolite 13X. In the case of combined modifications, the achieved separation efficiency is 66.51%. For the experimentation, an experimental setup fitted with artificial lungs. Characterization methods such as XRD, SEM, and EDX of cigarette filter, burnt charcoal part, ash, raw tobacco and mathematical calculation approve the improvement due to the modification of cigarette.

In this paper, we have investigated the transport of topological edge states in 2D Zigzag edge Tungsten Ditelluride Nanoribbon (ZTDNR).We have found that zigzag edge nanoribbon (NR) of Tungsten Ditelluride develops topological edge states in the presence of intrinsic spin orbit interaction (SOC). We have used three band tight binding model for the electrons of dz2 , dxy, and dx2 - y2 orbitals with SOC for calculating band structure of NR and Non Equilibrium Greens Function (NEGF) formalism for transport in the NR. We have investigated transport in a pristine device, transport in the presence of a finite potential barrier, transport with constriction within the device and transport with edge imperfections.

To further explore the development of construction waste recycling enterprises and promote the recycling of construction waste resources in China, a system dynamics model of the economic benefits of construction waste recycling enterprises is established using the system dynamics method and taking the tax incentive of the Guangzhou Municipal Government as an example. The economic benefits of construction waste recycling enterprises are analyzed from the perspective of the total cost, total revenue, and total recycling amount. The results of the MATLAB simulation and numerical analysis show that: (1) By simulating the effects of different taxes such as value-added tax (VAT), education surcharge, urban construction tax, and enterprise income tax on the economic benefits of construction waste recycling enterprises, it is found that when tax incentives reach 70%, the VAT favorable policies bring the highest gains, followed by enterprise income tax, whereas favorable education surcharge policies and urban construction tax have the least impact on economic benefits. (2) Taking the monetary subsidy of the Guangzhou municipal government as an example, it is estimated that the total revenue of construction waste recycling enterprises will increase by 33.56% annually in 2030. When the new production technology is adopted, the Return On Investment (ROI) will reach 46.8% in 2030 compared to previous technological improvement. In the simulation scenario, the ROI will be 42.2%, which has a good incentive effect on the cost control of enterprises. (3) Increasing the available power to VAT and corporate income tax can improve the profitability of construction waste recycling enterprises in China; however, tax incentive policy will no longer be the main factor affecting the benefits of enterprises when a certain time is reached. (4) It is suggested that the government improves the relevant tax laws incentive policies, increase tax incentives, and add equipment tax incentive policies, actively change the tax mode, and increase indirect tax models to improve the economic benefits of enterprises. The research results provide a decision-making reference for the government to formulate laws and policies related to the economic benefits of construction waste recycling, promote the development of the construction waste recycling industry, the development of new industries, such as waste recycling and treatment, and the formation of industrial chains, to achieve the strategic goal of sustainable development.

This study fabricated polylactic acid (PLA)/kenaf cellulose fiber biocomposite filaments via melt-extrusion process. Kenaf cellulose fibers (KF) were chemically extracted from locally grown kenaf plants and used as reinforcement. Moreover, the KF was then treated with tetraethyl orthosilicate (TEOS), so-called KFs, to improve the compatibility between the fibers and PLA matrix. Also, the plasticizers (polyethylene glycol) were incorporated to enhance the flowability and processability of the biocomposites. The melt viscosities of the biocomposites increased as the solid KF and KFs were loaded. However, they were significantly decreased with the addition of plasticizers. The combined use of the plasticizers and TEOS treatment improved tensile strength, Young’s modulus and elongation of the biocomposites compared to the neat PLA. The obtained PLA/KFs biocomposite materials are proved to be a mechanical-improved material, which offers the opportunity for customized and rapid prototyping of biocomposite products.
