Published: January 2021

Introduction of porosity into supramolecular gels endows soft materials with functionalities for molecular encapsulation, release, separation and conversion. Metal-organic polyhedra (MOPs), discrete coordination cages containing an internal cavity, have recently been employed as building blocks to construct polymeric gel networks with potential porosity. However, most of the materials can only be synthesized in organic solvents, and the examples of porous, MOP-based hydrogels are scarce. Here, we demonstrate the fabrication of porous hydrogels based on [Rh2(OH-bdc)2]12, a rhodium-based MOP containing hydroxyl groups on its periphery (OH-bdc = 5-hydroxy-1,3-benzenedicarboxylate). By simply deprotonating [Rh2(OH-bdc)2]12 with the base NaOH, the supramolecular polymerization between MOPs and organic linkers can be induced in the aqueous solution, leading to the kinetically controllable formation of hydrogels with hierarchical colloidal networks. When heating the deprotonated MOP, Nax[Rh24(O-bdc)x(OH-bdc)24-x], to induce gelation, the MOP was found to partially decompose, affecting the mechanical property of the resulting gels. By applying a post-synthetic deprotonation strategy, we show that the deprotonation degree of the MOP can be altered after the gel formation without serious decomposition of the MOPs. Gas sorption measurements confirmed the permanent porosity of the corresponding aerogels obtained from these MOP-based hydrogels, showing potentials for applications in gas sorption and catalysis.

Next-generation sequencing technologies enable doubling of the genomic databases every 2.5 years. Collected sequences represent a rich source of novel biocatalysts. However, the rate of accumulation of sequence data exceeds the rate of functional studies, calling for acceleration and miniaturization of biochemical assays. Here, we present an integrated platform employing bioinformatics, microanalytics, and microfluidics and its application for exploration of unmapped sequence space, using haloalkane dehalogenases as model enzymes. First, we employed bioinformatic analysis for identification of 2,905 putative dehalogenases and rational selection of 45 representative enzymes. Second, we expressed and experimentally characterized 24 enzymes showing sufficient solubility for microanalytical and microfluidic testing. Miniaturization increased the throughput to 20,000 reactions per day with 1000-fold lower protein consumption compared to conventional assays. A single run of the platform doubled dehalogenation toolbox of family members characterized over three decades. Importantly, the dehalogenase activities of nearly one-third of these novel biocatalysts far exceed that of most published HLDs. Two enzymes showed unusually narrow substrate specificity, never before reported for this enzyme family. The strategy is generally applicable to other enzyme families, paving the way towards the acceleration of the process of identification of novel biocatalysts for industrial applications but also for the collection of homogenous data for machine learning. The automated in silico workflow has been released as a user-friendly web-tool EnzymeMiner: https://loschmidt.chemi.muni.cz/enzymeminer/.
Enhancing the Electrocatalytic Activity and Stability of Prussian Blue Analogues Through the Introduction of Au Nanoparticles in a Core@shell Heterostructure
Authors: Sanchis-Gual Roger , Otero Toribio F. , Coronado-Puchau Marc , Coronado Eugenio
Published: January 2021

Prussian blue analogues (PBAs) have shown to be useful as earth-abundant electrocatalysts for the Oxygen Evolution Reaction (OER) in acidic, neutral and alkaline media. Still, further improvements can be achieved by increasing their electrical conductivity. In this work, we have obtained and fully characterized a variety of monodisperse core@shell hybrid nanoparticles of Au@PBA (PBA of NiIIFeII and CoIIFeII) with different shell sizes. Their electrocatalytical activity is evaluated by studying the OER, which is compared to the pristine PBA and other Au-PBA heterostructures. It was observed that the introduction in a core@shell of 5-10 % of Au in weight leads to an increment in the electroactive mass able to be reduced or oxidized and thus, to a higher number of sites capable to take part in the OER. This larger amount of electroactive sites leads to a significant decrease in the onset potential (a reduction of the onset potential up to 100 mV and an increase up to 420 % of the current density recorded at an overpotential of 350 mV), while the Tafel slope remains unchanged, suggesting that Au reduces the limiting potential of the catalyst with no variation in the reaction kinetics. These effects are not experimented in the other Au-PBA nanostructures mainly due to the lower contact between both compounds and the oxidation of Au. Hence, an Au core activates the PBA shell and increases the conductivity of the resulting hybrid while the PBA shell prevents Au oxidation. These improvements come from the strong synergistic effect existing in the core@shell structure and evidence the importance of the chemical design for preparing PBA-based nanostructures displaying better electrocatalytic performances and higher electrochemical stabilities.

Published: January 2021

Divalent iron complexes trans-[FeBr2(BINC)2], [Cp*FeCl(BINC)] (Cp* = Me5C5) and [FeBr2(CNAr3NC)2] with chelat-ing bis(isonitrile) ligands BINC (bis(2-isocyanophenyl)phenylphosphonate) and CNAr3NC (2,2’’-diisocyano-3,5,3’’,5’’tetramethyl-1,1’:3’,1’’-terphenyl) have been prepared and characterized. Their subsequent reduction yields di- and trinuclear compounds [Fe3(BINC)6], [Cp*Fe(BINC)]2, [Fe(CNAr3NC)2]2 and [K(Et2O)]2[Fe(CNAr3NC)2]2. The molecular structures of all new species were determined by X-ray crystallography. The molecular structures are compared to related iron carbonyl complexes. The complexes were further characterized by NMR and IR spectroscopy, and the electrochemical properties of selected compounds were analyzed by UV-Vis-NIR spectroelectrochemistry.

Published: January 2021

The research was featured to formulate, characterise and optimise the Azithromycin Proniosome using the three-factor three-level Box Behnken scheme. The independent variables chosen were span 20 (X1), span 80 (X2) and phospholipids (X3) to assess their individual and shared response on entrapment efficiency (Y1) and % drug released at six h (Y2). Based on Box Behnken design, 15 formulations were prepared and optimised using Design Expert Version 12.0.10.0. The entrapment efficiency and in-vitro drug release were exposed to different regressions to setup a polynomial equation. The counterplots understood the connections between the independent and dependent factors. The congruity of the polynomial equations was tested by fixing three checkpoint groups. The optimised formulation was determined by point prediction method using the various constraints. The optimised batch was subjected to multiple parameters such as vesicle shape, viscosity, spread ability, drug content, entrapment efficiency, in-vitro drug diffusion and stability studies. The optimised formulation shows better physical and chemical stability which is confirmed by the results of various parameters. The in-vitro drug diffusion has observed to be 98.53% at 24th h obeying zero-order drug release with diffusion mediated non-fickian type of drug release kinetics. The formulation preserved at both refrigerated and room temperature shows better stability. This approach might be an additional finding in enhancing the adherence of patient and improves compliance.

Published: January 2021

The present research dealt with the extraction and characterization of mucilage from the Hibiscus sabdariffa leaves. Compared with normal binding agents such as starch and Poly Vinyl Pyrrolidine (PVP), the mucilage of Hibiscus sabdariffa (HSM) was assessed for its binding properties in tablet formulations. Tablets were formulated using HSM, starch and PVP as binders at a various concentration to evaluate its comparative binding efficiency. The compressed tablets were analyze for their quality control tests as per IP. The extracted HSM showed the characteristics of mucilage and good physicochemical properties. The FTIR and thermal analysis compatibility tests showed that there were no significant reactions between the drug and mucilage. Granule properties of various formulations were found to be comparable and have excellent flow characteristics. Post compression parameters suggested that tablets formulated with mucilage had better hardness and friability as that of the tablets prepared with starch and PVP. The formulations exhibited a better and more consistent release as compared to standard formulations using starch and PVP as a binder. The statistical analysis of in vitro dissolution profile by using DD solver software for difference factor (f1), similarity factor (f2), and Rescigno index (ξ) values also indicated promising results. The results notably indicate that binding property of HSM was at par with starch and PVP.

Published: January 2021

Immunomodulation had been in application in medical systems and the traditional Indian systems like Ayurveda. It has various applications in medicine for altering the defence of the body that is immunity. A lot of conditions that require immunomodulation are supported by drugs for immune suppression and immune stimulation. They are often called as immune suppressants and immune stimulants. There are other class of drugs, immune adjuvants. Synthetic drugs are notorious for causing side effects and the herbal alternatives had been investigated for the activity. So the herbs stand as the alternatives for the synthetic drugs in better treating the disease that concern the immune system. The inconsistency of the in-vivo response of the immunity, with the phytochemicals, is also a limiting step for their effective usage as immunomodulatory agents when it comes to practical application. Overall, herbs had been supplying the chemical constituents that can be used directly or in the purified form as immunomodulatory agents. This review is the segregation of the various methods available to perform the screening of the drugs and extracts for immunomodulatory activity. This paper also enlists various herbs used for immunomodulation and had been proven for the same recently from 2010 to date.

Large-Scale Comparison of Authorship, Citations, and Tweets of Web of Science Authors
Authors: Ferreira Márcia R. , Mongeon Philippe , Costas Rodrigo
Published: January 2021

Social media platforms are increasingly part of the academic workflow. However, there is a lack of research that examines these activities, particularly at the author level. This paper explores the activity of researchers in the Twittersphere by analyzing a large database of Web of Science authors systematically identified on Twitter using data from Altmetric.com. Using this information, this paper explores and compares patterns of tweeted and self-tweeted publications with other academic activities, such as citations, self-citations, and authorship at the author level. This paper also compares the thematic orientation among these different activities by analyzing the similarity of the research topics of the publications tweeted, cited, and authored. The results show that the productivity and impact of researchers, as defined by conventional bibliometric indicators, are not correlated to their popularity on the Twitter platform and that scholars generally tend to tweet about topics closely related to the publications they author and cite. These findings suggest that social media metrics capture a broader aspect of the academic workflow that is most likely related to science communication, dissemination, and engagement with wider audiences and that differs from conventional forms of impact as captured by citations. Areas for further exploration are also proposed.1
INDICATORS OF ECONOMIC DEVELOPMENT OF REGIONS AND ROBOTIZATION OF AGRICULTURE
Authors: Nabokov Vladimir , Skvorcov Egor , Pryadilina Natal'ya
Published: January 2021

The processes of robotization of production occur in various industries, including such a conservative industry as agriculture. The aim of the study is to identify the territorial patterns of robotization of agriculture in the regions in relation to the indicators of their economic development. Regression analysis and Internet screening were used as research methods. Regional offices of the Ministry of Agriculture and Agribusiness provided data on the use of 435 units of robots used in the industry. In general, in the Russian Federation, the density of robotization of agriculture was 0.7497 robots per 10 thousand people employed in the industry. The density of robotization of agriculture by federal districts and regions was determined and the corresponding ranks were assigned to them. The author's methodology for ranking regions by robotization density is proposed, which is proposed to be divided into regions with high (over 3.0 robots per 10 thousand working in the industry), medium (from 0.75 to 3.0) and low density (less than 0.75 ) robotization. The average level of correlation between the gross agricultural output and the number of implemented robots was revealed (0.63). A high correlation is observed between labor productivity in agriculture and the number of implemented robots (0.78). There is a negative correlation between the share of agriculture in the gross value added of the regions and the amount of robotics used (-0.52) and the density of robotization (-0.59). This may indicate that robotics is used to a lesser extent in regions with traditionally developed agriculture. In the future, this may cause a technological lag in regions with a high share of agriculture, which must be taken into account by the executive authorities when developing programs for the innovative development of the industry.
EFFICIENCY OF CORPORATE FINANCE: FORMATION OF ACCOUNTING AND MANAGEMENT TOOLS
Authors: Il'in Sergey , Ostaev Gamlet , Gogolev Igor' , Zlobina Oksana
Published: January 2021

The article presents a system of indicators developed by the authors, which is offered to corporations to assess the efficiency of their financial relations by the accounting and management apparatus, which play a key role in business due to the greatest liquidity of monetary resources in the modern economic era. The tools of such a system are based on the study of controlled and uncontrolled conditions of corporate functioning. Controlled conditions include economic processes in their expanded understanding, uncontrolled conditions-microenvironment and macroenvironment of corporations, which require them to bear the corresponding monetary costs, compared with the result obtained from them (profit in relation to the commercial sector of the economy). the argument of this approach to the formation of the proposed tools consists in the diversification and multi-vector nature of corporate business processes, which entail a wide range of costs for the maximum attraction of financial benefits from each type of activity, while simultaneously ensuring parity of accounting and economic indicators (reducing to zero the level of imputed costs that generate lost profits in value terms). the use of the recommended author's approach by corporations will ensure that they optimize the result and costs (profit and expenses) and, accordingly, the effectiveness and cost (direct and indirect profitability or profitability) of their activities, which determine their financial efficiency.

Perspektif dan Frame Ekspresi Permintaan Maaf dalam Diskusi Indonesian Lawyers Club “50 Tahun G30S/PKI, Perlukah Negara Minta Maaf?”: Kajian Linguistik Kognitif
Authors: Musyayyab Imam , Arimi Sailal
Published: January 2021

Abstrak: Pidato kepresidenan pada HUT RI ke-70 menuai kontroversi. Sebagian masyarakat berasumsi bahwa negara akan meminta maaf kepada para “korban” pelanggaran HAM yang merujuk kepada pihak Partai Komunis Indonesia (PKI). Pada 29 September 2015, Indonesian Lawyers Club (ILC) menggelar diskusi dengan tema “50 Tahun G30S/PKI: Perlukah Negara Minta Maaf?” untuk menanggapi isu tersebut. Saat diskusi berlangsung, para tamu undangan saling tunjuk pihak yang seharusnya meminta maaf. Akibatnya, banyak sudut pandang yang membiaskan subjek yang seharusnya meminta maaf. Peneliti menelusuri fenomena ini lewat kajian Linguistik Kognitif untuk membongkar perspektif dan latar belakang pengetahuan (frame) permintaan maaf. Peneliti mentranskripsikan data dengan menggunakan metode simak teknik sadap dan catat. Setelah itu, peneliti mengklasifikasi dan menganalisisnya dengan metode padan. Hasilnya, perspektif mengenai wacana permintaan maaf terwujud dengan adanya pengutamaan (subjek) dari setiap ekspresi kebahasaan, yaitu perspektif dengan subjek pihak keluarga dan terduga PKI, perspektif dengan subjek pihak TNI AD, dan perspektif dengan subjek pihak NU dan Muhammadiyah. Peneliti mengklasifikasikan frame, pengetahuan yang melatari terbentuknya sebuah konsep, menjadi tiga frame yang berbeda berdasarkan waktunya, yaitu waktu sebelum peristiwa G30S (pihak NU dan Muhammadiyah), saat terjadi peristiwa G30S (pihak TNI AD), dan setelah peristiwa G30S (pihak keluarga dan terduga PKI).
Abstract: The Presidential Speech at the 70th Indonesian Independence Day caused a controversy. Some people assumed that the state would apologize to the victims of the human rights violations mentioning the Indonesian Communist Party (PKI). On 29 September 2015, the Indonesian Lawyers Club (ILC) held a discussion bringing up the theme “50 Tahun G30S/PKI: Perlukah Negara Minta Maaf?” to respond to the issue. During the discussion, the invited guests pointed to each others who should apologize. The researchers investigate this phenomenon with Cognitive Linguistic studies to reveal perspectives and beckground knowledge (frames) of apologies. The researchers transcribed the data using the observation method of tapping and note-taking techniques. After that, the researchers classified and analysed using the matching method. Based on the analysis carried out, perspective on apologies are manifested by the prioritisation (subject) of each linguistic expression, i.e., perspectives with the subject of the family and suspected PKI, perspective with the subject of the Army (TNI), and perspective with the subjects of the NU and Muhammadiyah. In this study, the researchers classified three different frames, the knowledge behind the formation of a concept, based on the time, namely the time before the G30S incident (the NU and Muhammadiyah parties), the time of G30S event (TNI), and after the G30S (PKI family and suspected PKI).

Low-carbon steel Q235B was successfully joined by plasma-pulsed gas metal arc welding (plasma-GMAW-P) with an external magnetic field. The arc profile, temperature field, electrical signal, microstructure, and mechanical properties of this method were analyzed. The results indicated that the coupling degree of the two arcs increased with the strengthening of the magnetic field current. However, when the magnetic field current was greater than 1 A, the arc pro-file changed slightly with the increase of the magnetic field current. Fixed on the magnetic field current, the coupling degree first increased and then decreased with the increase of the plasma welding current, GMAW-P welding current, plasma gas flow rate, and nozzle height, respectively. The maximum temperature had no obvious influence on joint penetration at different magnetic field cur-rents. However, the average temperature had an inverse effect on joint penetration at different magnetic field currents. The weld fusion zone joint tensile test results showed that the ratio of depth to width increased with the application of magnetic field currents. Moreover, tensile strength on the upper and lower part of the tensile samples were 521 and 488 MPa, respectively, which were 4.6% and 3.2% higher than those without the magnetic field. The microhardness of the weld joints was higher than that without the magnetic field.

Short-pulse welding parameters for resistance spot welding (RSW) of aluminum alloy AA6016-T4 using mediumfrequency direct current (MFDC) systems were developed to reduce the heat input required for nugget formation. Optimization of current and time parameters is critical during RSW of aluminum alloys for reducing energy requirements and avoiding weld imperfections, such as solidification cracking and expulsion, while maintaining weld quality, particularly given the high electrical and thermal conductivities of the materials. The welding time and the applied current level of the current pulse were varied systematically for thin sheets (1 mm or 0.04 in.) of AA6016-T4. The quality of the welds was evaluated by pull-out testing, ultrasound testing, and metallography techniques. Simulations of the same welding processes were performed with the finite element-based SORPAS® software. The results showed short-pulse MFDC RSW can reduce the energy required for sound welds in this alloy without requiring an increase in welding current. The simulations and experiments also showed the welding process had distinct weld nugget nucleation and growth phases.
Language, Sexism and Misogyny
The Reception of Women’s Political Speech
Authors: Cameron Deborah
Published: January 2021

This paper examines linguistic sexism and misogyny in the light of the philosopher Kate Manne’s recent proposals regarding the general definitions of these concepts and their relationship. Using the reception of female politicians’ speech as an illustration, it argues that misogyny can be expressed through a range of interactional and representational practices; many of these would not amount to ‘hate speech’ in the legal sense, but that does not mean they are innocuous. From a feminist perspective linguistic misogyny, together with sexism, can most usefully be understood as fulfilling an important political function in patriarchal societies: policing women’s public speech and undermining their claims to authority.
What Women Want? A Multimodal Critical Discourse Analysis of UK Media Constructions of (LGBTQ+) Female Voters
Authors: Verheijen Lotte
Published: January 2021

Sexist media depictions of female politicians have been studied. However, studies regarding portrayals of female voters and their hetero/cisnormative narratives are lacking. Therefore, this study explores UK media constructions of female voters in the context of the 2016 EU Referendum and the 2017 General Election via corpus-assisted CDA. It mainly focuses on the exclusion of LGBTQ+ women as voters via hetero/cisnormative language use. Female voters tend to be depicted in relation to men, or children and a family in general, while mentions of queer women are rare. Moreover, LGBTQ+ rights chiefly feature in political discourse to further a nationalist agenda through homonationalist arguments.
For a Bottom-Up Approach to the Linguistic and Legal Definition of Hate Speech
A Case Study of Offences Against Women
Authors: Ferrucci Francesca
Published: January 2021

In addressing the legal definition of Hate Speech (HS), some important linguistic issues arise: the necessity of semantic precision of normative texts conflicts with the difficulty of tracing distinctive features of the phenomenon; the balancing with freedom of expression poses the question on the boundaries between opinions and verbal violence. Comparative studies on national laws show significant gaps in definitions, highlighting their negative effects. This paper discusses the problem analysing a corpus of 2,720 Facebook negative comments against women with decisional positions in Europe. Recurring textual strategies are identified testing a bottom-up approach, argued as the appropriate method to meet the current research challenges.
Subtle Gender Stereotypes in the News Media and Their Role in Reinforcing a Culture Tolerating Violence Against Women
Authors: Azzalini Monia
Published: January 2021

This paper examines how news media play a crucial role in tolerating gender-based violence by constantly reinforcing ‘subtle’ gender stereotypes. After presenting the institutional background in which media, gender stereotypes and gender-based violence have been studied over the last 30 years, subtle gender stereotypes are defined as those stereotypes that are less evident than the obvious ones and are not usually correlated to gender violence. Nevertheless, they can be detected in the underrepresentation and misrepresentation of women in the news, as measured by the GMMP (Global Media Monitoring Project), which is the longest and most extensive study on the representation of women in news media.
Fish Biodiversity Assemblages and Fishing Gears Used at Chinadi Beel in Narsingdi District of Bangladesh
Authors: Majumdar Bhaskar Chandra
Published: January 2021

The present survey disclosed the available fish biodiversity and the gears used for fishing in the Chinadi beel, Narsingdi, Bangladesh, for a certain period. Data was collected through face to face conversations using a well-structured questionnaire and cross-checked. About 51 species of fish under 7 orders and 19 families were found. The dominant order was found jointly for Cypriniformes (29.41%) and Siluriformes (29.41%). About 39 least concern (75%), 5 vulnerable (9.62%), 6 near threatened (11.54%), and 1 not evaluated (1.92%) species were observed. Fifteen different types of fishing gears (8 major categories) are used for fishing by the fishermen, of which seine net was the most leading gear. Most of the gears are banned for a period due to its unauthorized mesh size. The price of fishing gears was ranged from 250-1,00,000 Tk, of which the highest price was for seine net. The uppermost catch per unit effort (CPUE) was found for ber jal that was 15-18 kg/day. Most of the fishing gear was operated throughout the year, but limited in the dry season. However, the variety of fish abundance and species diversity is declining day by day in this beel. To protect the fish diversity of the Chinadi beel, it is recommended to establish effective fishery management practices, monitoring overfishing, and awareness of fishermen is highly recommended.
Land Use / Land Cover Mapping of Nahra Nala Watershed Using Sentinel-2B Imagery
Authors: Patle Deepak
Published: January 2021

Land is a limited natural resource which restricts no further increase in a cultivated area. Moreover, due to the increasing population, the pressure on this resource is increasing day by day. Hence, land use/land cover (LU/LC) information is very much necessary for the best possible use by maximizing outputs sustainably from this diminishing resource such that good planning and management can be done to meet the demand of the ever-increasing population. Therefore, a study has been conducted for land use/land cover mapping using SENTINEL-2B satellite data having a fine spatial resolution of Nahra nala watershed, which is a tributary of Wainganga river situated in Balaghat district of Madhya Pradesh, India. Five land use/land cover classes were identified, namely water bodies, agricultural land, forest, habitation (built-up), and wasteland in the study area. The study area possesses forest as the predominant LU/LC class with 83.79 percent of the total geographical area of the watershed. Accuracy assessment was also applied to the final classified results based on the ground truth points or known reference pixels along with Google Earth imageries. The overall classification accuracy of 95.52% with the kappa value of 0.92 was achieved.
