JURIDICAL REVIEW OF THE IMPLEMENTATION OF A PARTICULAR TIME AGREEMENT BASED ON LAW NUMBER 13 OF 2003 CONCERNING MANPOWER
Authors: Bunadi Bunadi , miharja Marjan 
Published: March 2021

Industrial relations disputes are common in many companies. The dismissal process is often not in accordance with the provisions of labor regulations, one of which is regarding the dismissal of PKWT / contract workers. The formulation of the problems that the author discusses in this thesis are (1) What is the role of trade unions in fighting for dismissal disputes with PKWT / Contract workers? (2) Is the Application of a Fixed Time Work Agreement (PKWT) in accordance with the provisions of Law Number 13 Year 2003 concerning Manpower?
The research method used in this research is juridical normative, namely looking at the law as a written norm made and promulgated by an authorized official or institution, the nature of descriptive analytical research is a study to obtain an overview of the main object of the problem being researched. The results showed that, the role of trade unions in companies in fighting for dismissal disputes against PKWT / Contract workers in accordance with Law no. 2 of 2004 concerning PPHI article 6 in conjunction with article 8 in conjunction with article 81, namely by conducting a bipartite effort between the labor union and the company, because the bipartite effort failed, then submitted a mediation request to the Manpower Office. The mediation attempt still failed and subsequently filed a lawsuit for dismissal disputes at the Industrial Relations Court, although it was unsuccessful. The application of a fixed-term employment agreement (PKWT) is contrary to the provisions of Law number 13 of 2003 concerning Manpower Article 59 paragraphs (1), (2), and (7). In addition, the PHI Judge in deciding the case did not reflect a sense of justice and ignored the evidence presented by the plaintiff (the worker).
This problem should not have occurred, if the company obeyed and understood the labor regulations regarding workers who could be promised under a non-permanent contract or PKWTT.

Published: March 2021

Background: The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the only zoonotic-origin CoV to reach the pandemic stage, to which neither an effective vaccine nor a specific therapy is available. The spike glycoprotein harbors the receptor-binding domain (RBD) that mediates the virus's entry to host cells. This study aimed to identify novel inhibitors that target the spike protein's RBD domain through computational screening of chemical and natural compounds. Method: The spike protein was modeled from the recently reported electron microscopy protein structure (PDB ID: 6VSB) and the previously described SARS-CoV protein structure (PDB ID: 6ACD and 6ACJ). Virtual lab bench CLC Drug Discovery was used to computationally screen for potential inhibitory effects of currently prescribed drugs (n = 22), natural antiviral drugs (n = 100), and natural compounds (n = 35032). Quantitative Structure-Activity Relationship (QSAR) studies were also performed to determine the leading binders known for their antiviral activity. Results: Among the drugs currently used to treat SARS-CoV2, hydroxychloroquine and favipiravir were identified as the best binders with an average of four H-bonds, with a binding affinity of − 36.66 kcal/mol and a minimum interaction energy of − 6.63 kcal/mol. In an evaluation of antiviral compounds, fosamprenavir and abacavir showed effective binding of five H-bonds, with an average binding affinity of − 18.75 kcal.mol− 1 and minimum interaction energy of − 3.57 kcal/mol. Furthermore, screening of 100 natural antiviral compounds predicted potential binding modes of glycyrrhizin, nepritin, punicalagin, epigallocatechin gallate, and theaflavin (average binding affinity of − 49.88 kcal/mol and minimum interaction energy of − 4.35 kcal/mol). Additionally, the study reports a list of 25 natural compounds that showed effective binding with an improved average binding affinity of − 51.46 kcal/mol. Conclusions: Using computational screening, we identified potential SARS-CoV-2 S glycoprotein inhibitors that bind to the RBD region. Using structure-based design and combination-based drug therapy, the identified molecules could be used to generate anti-SARS-CoV-2 drug candidates.

Published: March 2021

Abstract
The Freiberg district hosts one of the largest series of epithermal polymetallic vein deposits in Europe. The availability of a systematic collection of historical samples provides an excellent opportunity to study the anatomy of these epithermal systems. Detailed petrographic investigations, geochemical analyses, and fluid inclusion studies were conducted on several vertical profiles within the Freiberg district to decipher mineralogical and geochemical zoning patterns. Six distinctive mineral associations have been recognized within the Freiberg epithermal veins; sphalerite-pyrite-quartz and galena-quartz±carbonate associations are most abundant in the central sector, as well as in the deepest sections of veins on the periphery of the district. A high-grade sphalerite-Ag-sulfides-carbonate association occurs laterally between the central and peripheral sectors and at intermediate depth in veins on the periphery. Shallow and peripheral zones are dominated by an exceptionally Ag-rich Ag-sulfides-quartz association, whereas the shallowest veins locally comprise Ag-poor stibnite-quartz and quartz-carbonate associations. Fluid inclusion assemblages returned low salinities (&lt;6.0 wt % NaCl equiv), and homogenization temperatures successively decrease from ~320°C associated with the proximal and deep sphalerite-pyrite-quartz association, to ~170°C related to the distal and shallow Ag-sulfides-quartz association.
The architecture of the Freiberg district is related to the temporal and spatial evolution of magmatic-hydrothermal fluid systems, including boiling and concomitant cooling, as well as CO2 loss. Constraints on the paleodepth indicate that the veins formed between 200 and 1,800 m below the paleowater table. High-grade Ag ore occurs over a vertical interval of at least 500 m and is bracketed by shallower stibnite-quartz and barren quartz, and deeper base metal-sulfide-quartz zones.

Abstract
The late Neoarchean, ~2.53 to 2.51 Ga Dagushan banded iron formation (BIF), is a typical Algoma-type BIF located in the northeast part of the North China craton. Despite having undergone upper greenschist to lower amphibolite facies metamorphism, the Dagushan BIF retains evidence of varied depositional facies, making it an ideal archive to evaluate the paleomarine environment and the paragenesis of the ore minerals. A transition from oxide to silicate to carbonate facies BIF is evident in a northward direction. The mineralogical composition shifts from magnetite and quartz in the south through a magnetite-quartz-cummingtonite/stilpnomelane assemblage in the transition zone to magnetite-siderite in the north. Such a distinct distribution of mineralogical facies correlates well with the depositional environment of the BIF. The carbonate facies BIFs formed in a near-shore, proximal environment, whereas the oxide and silicate facies BIF assemblages formed in deeper waters, distal to the paleoshoreline. The BIF samples display characteristic seawater-like rare earth element + yttrium (REE + Y) profiles with positive La and Y anomalies and heavy REE enrichment relative to the light REEs when normalized to post-Archean Australian shale. Positive Eu anomalies suggest a high-temperature hydrothermal contribution to the BIF. The absence of a negative Ce anomaly in nearly all samples, coupled with positive δ56Fe in magnetite in all mineralogical facies, indicates a dominantly anoxic water column contemporaneous with deposition of the BIF. At ~2.53 Ga in the Anshan area, seawater was mostly anoxic and rich in ferrous iron. Dissolved ferrous iron in upwelling hydrothermal fluids was oxidized and precipitated as Fe(III) oxyhydroxides in the photic zone leading to BIF formation. Proximal to hydrothermal vents, magnetite formed via the reaction of Fe(III) oxyhydroxides and aqueous Fe(II) supplied from the hydrothermal fluids and microbial dissimilatory iron reduction (DIR) coupled to organic carbon oxidation. Proximal to a paleoshoreline, siderite formed through DIR, as evidenced by the depleted δ13C values and the presence of graphite. Silicates, such as stilpnomelane and cummingtonite, are considered to be the metamorphic products of early diagenetic silicates (e.g., nontronite) that formed in the water column from admixtures of Fe(III) oxyhydroxides and amorphous silica.

Information about immunization of the under five children. Data were analysed by using SPSS software.
Results: In this study, among the 247 children studied, 61.94% were fully immunised, 38.05 were partially immunised. The most common reason for defaulting vaccination were knowledge (25.5%) followed by illness of the child (14.1%)
Conclusion: The availability of better healthcare facilities like government medical college in the proximity of these slums has led to good health seeking behaviour among them.
Star Players in the NBA - Decoys or Game-Changers?
Authors: Liu Yangmufeng 
Published: March 2021

In the National Basketball Association (NBA), when an attacking team is trailing by a small margin in the last seconds of
a game, the coach has to make a critical decision: should he or she design a play for the star player or a non-star player&#39;s
In this strategic situation, the o ensive team can choose to let either the star or the non-star to shoot the ball while the
defensive team can either double-team the star player or play conventional one-on-one defence. For the purpose of this
research, star players are divided into two types - perimeter and interior. Given di erent point deficits, an equilibrium
point is obtained and comparative statics are computed to analyze how the equilibrium will change given a change in a
player&#39;s shot percentage. It is found that the o ensive team should play the star player at most 3 out of 10 times in all
scenarios.

Context.—
ABO mistransfusions are rare and potentially fatal events. Protocols are required by regulatory agencies to minimize this risk to patients, but how these are applied in the context of massive transfusion protocols (MTPs) is not specifically defined.

Objective.—
To evaluate the approaches used by transfusion services for switching from universally compatible to patient ABO type-specific blood components during massive hemorrhage.

Design.—
We added 1 supplemental multiple-choice question to address the study objective to the 2019 College of American Pathologists proficiency test J-survey (J-A 2019). We also reviewed the available literature regarding this topic.

Results.—
A total of 881 laboratories responded to the supplemental question. Approximately 80% (704 of 881) reported a policy for ABO-type switching during an MTP. Policies varied considerably between responding laboratories, but most (384 of 704, 55%) required 2 ABO types to match before switching from universal to recipient-specific blood components. Additional safety measures used in a minority of these protocols included reaction strength criteria (103 of 704, 15%), on-call medical director approval (41 0f 704, 5.8%), universal red cell unit number limits (12 of 704, 1.7%), or the presence of a mixed field (3 of 704, 0.4%).

Conclusions.—
This survey reveals that significant heterogeneity exists regarding the available approaches for ABO-type switching during an MTP. Specific expert guidance regarding this issue is very limited, and best practices have not yet been established or rigorously investigated.

Esta pesquisa objetiva investigar a atitude e o comportamento do turista de sol e praia em relação à sustentabilidade, verificando a influência da atitude e do comportamento habitual no comportamento em viagem. Para tanto, realizou-se esta pesquisa em Jericoacoara, situada no Estado do Ceará, nordeste brasileiro. A pesquisa é caracterizada como quantitativa, realizada por meio de survey e foi aplicada com 188 turistas de sol e praia. Os resultados evidenciam que as atitudes sustentáveis influenciam o comportamento sustentável em viagem, de modo que a atitude de crença antropocêntrica teve efeito negativo, enquanto as atitudes de crença ecocêntrica relacionadas aos recursos naturais e ao consumo tiveram efeito positivo. No tocante aos comportamentos sustentáveis habituais, verificou-se influência positiva dos comportamentos relacionados à reciclagem, economia de água e energia e limpeza urbana no comportamento sustentável em viagem. Dessa forma, pode-se compreender que o indivíduo que apresenta atitudes e comportamentos sustentáveis em seu cotidiano tende a estendê-los a diversos ambientes, confirmando o ditado popular de que “costume de casa vai à praça”, no caso, à praia.
As leis da hospitalidade
Authors: Camargo Luiz Octávio de Lima 
Published: March 2021

Na sociedade de mobilidade crescente, que vem substituindo a sociedade à dominante sedentária, o contato com estranhos/estrangeiros/desconhecidos aumenta velozmente, alterando instituições basilares da sociedade como casa, vizinhança, família, trabalho. A garantia de ser bem recebido em todos os lugares para onde vamos torna-se uma necessidade. A urbanidade, o tratamento polido, mas impessoal não é mais suficiente. Crescem as reivindicações por uma hospitalidade mais carregada de calor humano. Mesmo no comércio, termos como customização, fidelização são marcas da aspiração de pessoalidade no encontro. A discussão desses temas é o contexto para o propósito deste artigo de, com base nas reflexões de Jacques Derrida, Marcel Mauss, Julian Pitt-Rivers e Anne Gotman, desvelar as quatro leis básicas da hospitalidade: a incondicionalidade, a reciprocidade, a assimetria e a compensação. Adicionalmente, pretende levantar outras questões que surgem à margem da atual discussão, em especial o caso do turismo.

AbstractSingle‐atom metal (SA‐M) catalysts with high dispersion of active metal sites allow maximum atomic utilization. Conventional synthesis of SA‐M catalysts involves high‐temperature treatments, leading to low yield with a random distribution of atoms. Herein, a nature‐based facile method to synthesize SA‐M catalysts (M = Fe, Ir, Pt, Ru, Cu, or Pd) in a single step at ambient temperature, using the extracellular electron transfer capability of Geobacter sulfurreducens (GS), is presented. Interestingly, the SA‐M is coordinated to three nitrogen atoms adopting an MN3 on the surface of GS. Dry samples of SA‐Ir@GS without further heat treatment show exceptionally high activity for oxygen evolution reaction when compared to benchmark IrO2 catalyst and comparable hydrogen evolution reaction activity to commercial 10 wt% Pt/C. The SA‐Ir@GS exhibits the best water‐splitting performance compared to other SA‐M@GS, showing a low applied potential of 1.65 V to achieve 10 mA cm−2 in 1.0 M KOH with cycling over 5 h. The density functional calculations reveal that the large adsorption energy of H2O and moderate adsorption energies of reactants and reaction intermediates for SA‐Ir@GS favorably improve its activity. This synthesis method at room temperature provides a versatile platform for the preparation of SA‐M catalysts for various applications by merely altering the metal precursors.

Published: March 2021

AbstractIron–platinum (Fe–Pt) compounds are well known for their interesting magnetic and electrocatalytic properties. However, iron segregation and iron oxides formation under oxidative conditions may influence the characteristics of Fe–Pt systems. Several approaches are used to protect the Fe–Pt compounds from oxidation, the most promising of which involves covering the material with a protective graphitic layer. By performing model‐type ultrahigh vacuum (UHV) studies, it is shown that a layer of epitaxial graphene (Gr) grown on a [111]‐oriented single‐crystal platinum substrate with thermally dissolved iron (Fe–Pt(111) surface alloy) effectively blocks iron segregation and iron oxides formation under oxidative conditions, while still allowing for the adsorption of oxygen atoms underneath the carbon layer. The oxidation is monitored in real time and at the micrometer scale using low energy electron microscopy (LEEM) and local diffraction (μLEED). Notably, a similar result is obtained for a poorly ordered Gr‐like carbon layer grown directly on a Fe–Pt(111) substrate. The findings are rationalized in terms of a locally lowered partial oxygen pressure and inhibited iron oxide growth in a confined space between the carbon layer and the metal support.
Highly Conductive Silicone Elastomers via Environment‐Friendly Swelling and In Situ Synthesis of Silver Nanoparticles
Authors: Yang Yuanhang , Duan Shun , Zhao Hong 
Published: March 2021

AbstractFlexible and stretchable conductors are crucial components for next‐generation flexible devices. Wrinkled structures often have been created on such conductors by depositing conductive materials on the pre‐stretched or organic solvent swollen samples. Herein, water swelling is first proposed to generate the wrinkled structures on silicone elastomers. By immersing silicone/sugar hybrid in water, a significant amount of swelling occurs as a result of osmosis and capillary interactions with the sugar and silicone matrix. Considering the drastic swelling effect and controllable swelling ratio, water swelling is used to replace the conventional pre‐stretching and organic solvent swelling to fabricate stretchable conductors. In situ growing of silver nanoparticles (AgNPs) is carried out on the swollen silicone elastomers. Wrinkled conductive silicone elastomers are successfully constructed after removing the residual water. The conductive elastomer has a sheet resistance of less than 1 Ω sq‐1 at zero strain and also shows high sensitivity when subjected to external deformation up to 100% strain. The silicone/sugar composite also possesses good 3D printability with the desired shear‐thinning property. Human motion detection is demonstrated using the 3D printed sensors. This work provides a facile and environment‐friendly strategy to fabricate superior flexible and stretchable sensing devices.
Polarized Photoluminescence from Lead Halide Perovskites

Published: March 2021

AbstractSolution‐processable lead halide perovskites possess excellent optical and electronic properties as one of the best candidates for optoelectronics. Especially, some of the perovskites show high quantum efficiency in photoluminescence, which enables their promising application in next‐generation light‐emitting materials and devices. More interestingly, the highly crystalline nature of perovskites as well as the intrinsic spin selectivity of exciton transitions introduces fascinating polarization properties into the light emission from lead halide perovskites. Herein are summarized the recent advances in the studies of polarized photoluminescence from lead halide perovskites in terms of both in‐depth understanding and potential application. The bright excitons in perovskite materials provide spin sublevels that give rise to radiative transitions carrying angular momentum, which is essential for the observation of polarized light emission. The polarization in photoluminescence can be amplified or modulated by introducing functional units such as chiral ligands in the chemical components of perovskites. Incorporating highly ordered microstructures into the perovskite materials is proved to be an effective way to further enhance the polarization properties at the macroscopic scale. The chemical and structural versatility of lead halide perovskites allows utililization of their characteristics of optical polarization in the construction of light sources, photodetectors, display devices, and so on.
