Authors: Dahlia Nauly , Harianto  , Sri Hartoyo , Tanti Novianti
Published: May 2022

The Indonesian government issued a policy that restricts foreign ownership in several industries including the food industry, with the objective of protecting the domestically owned firm. This research analyzed the productivity differences between foreign-owned and domestically owned plants in the Indonesian food industry and whether the percentage of foreign ownership is related to productivity. Micro data on the food industry were obtained from the Annual Survey of Large and Medium scale Industries (IBS) in 2015 conducted by Statistics Indonesia. The results showed that there were productivity differences between the foreign-owned and domestically owned plants. The foreign-owned plants had higher productivity than the domestic plants. The productivity of plants with minority foreign ownership (less than 50 percent) was not significantly different from that of domestically owned plants. Meanwhile, the productivity of plants with foreign ownership more than 50 percent was significantly different from that of plants with domestic ownership. Wholly foreignowned plants (100 percent) did not demonstrate the highest productivity difference. When the data were disaggregated at the sub-sector level, the results varied among industries.

Authors: Barsoum Zakaria
Published: May 2022

Background: Acute gastroenteritis (GE) is a clinical syndrome and harbours a significant global burden. Nosocomial acquisition of gastroenteritis results in a significant economic burden. We aim to determine gastroenteritis frequency, disease severity, nosocomial acquisition and clinical spectrum in our region in 2016-2017.

Methods: Prospective study of all children up to 3 years of age who presented to Mayo University Hospital with vomiting and diarrhoea, from November 18th 2016 to November 18th 2017. All children had their clinical severity of gastroenteritis assessed using internationally recognised Vesikari scoring system.

Results: 159 cases were detected, 157 were studied, 87 were male (55%), 90 severe (57%). Nosocomial gastroenteritis was rare (2 cases) (1.1%); 129 cases were admitted, the majority of paediatric gastroenteritis cases (68%) stayed between 1-2 days. Diarrhoea was noted in all cases, vomiting (130 cases, 82%), fever (136, 86%), dehydration (89, 56%). Oral Rehydration Therapy was successful in 33 cases (21%). The fourth week of June was the week peak of the year for gastroenteritis (7 cases). The largest number of presentations with GE was noted in May (20 cases) followed by December and June (18 cases each) with the largest number of severe GE noted in June (12 cases) followed by December and May (11cases each).

Conclusion: Diarrhoea is the most predominant feature of gastroenteritis. Acute viral gastroenteritis occurs throughout the year. Seasonal variation of gastroenteritis was noted throughout the year. Nosocomial infection was rare.

Authors: Thu Vu Thi , Yen Ngo Thi Hai
Published: May 2022

This study was conducted to evaluate the effect of Naringin (NAR) on multiple myeloma cells through assessment of cell proliferation and mitochondrial function. Methods: Human myeloma cell line (KMS-20) was subjected to normal (control) and treatment conditions. The viability, toxicity, cardiolipin content and mitochondrial membrane potential of KMS-20 cells in all groups were analyzed by using suitable kits. Results: The obtained data showed that NAR is toxic and inhibits the growth of KMS-20 cells. Similar to Doxorubicin (DOX)-treated cell group, the KMS-20 cell group supplemented with NAR had a sharp decrease in cardiolipin content compared to those in control group. The cardiolipin contents of KMS-20 cells in the DOX- and NAR-treated groups were 38.78±3.74 and 47.23±4.65 (% of control, p<0.05), respectively. In contrast to DOX, NAR strongly elevated the mitochondrial membrane potential of the KMS-20 cells. Conclusion: This study shows that NAR has the ability to inhibit the growth of KMS-20 multiple myeloma celline by altering their mitochondrial structure and function.

Authors: Suhud Usep , Purnamasari Laila , Allan Mamoon
Published: May 2022

So far, however, there has been little discussion about the online behaviour for micro and small size entrepreneurs in the pertinent literature. Therefore, this study examines the online behaviour of micro and small business owners of Facebook users using the linear and non-linear AISAS (attention, interest, search, action, and sharing) models. Scholars have tested this model with various types of consumer groups, except business owners. To that end, the current study involves micro and small business owners who join a group on Facebook. Data were collected in Greater Jakarta, Indonesia, and analysed using exploratory factor analysis (EFA) and structural equation modelling (SEM). As a result, the AISAS linear model succeeded in predicting micro and small business owners' online behaviour. Simultaneously, there were several problems with the non-linear model in predicting the online behaviour of small business owners.
"Epic sound patterns": sonata for harp No. 2 by Valery Kikta in the light of the peculiarities of the genre
Authors: Aldakov Ilia Andreevich
Published: May 2022

This article examines the sonata for solo harp No. 2 "Epic sound patterns" by Valery Kikta in order to identify the genre features that form the basis of the artistic task. The Russian harp school has passed its own path of formation and has a recognized authority. Despite this fact, compositions for solo harp in the works of modern Russian authors are quite rare. Valery Kikta became one of the composers seeking to revive interest in the national harp art and advocating the preservation of tradition. His main achievement in this field is not only in the creation of new music, firmly included in the performing and concert repertoire, but also participation in the organization of the Russian Harp Society. The three iconic characteristics of the composition analyzed by the author of the article – genre, timbre and fret – made it possible to define a work of musical art as a text that can be deciphered. In the process of work, special attention is paid to the detailed characteristics of traditional and innovative ways of working with the material. Special emphasis is placed on the search for links with the Russian school of composition and its characteristic reliance on national culture. The semiosis of the sonata and its constituent expressive features of the musical language are determined. The symbolism of the epic in combination with the software component announced by the author made it possible to discover the "message" contained in it.

Authors: Kumar Deepak , Basu Somnath , Goyal Ramesh K , Sahoo Pravat Kumar , Mathur Rajani
Published: May 2022

Objectives:

This study compares the adverse effects (AEs) associated with trastuzumab in the treatment of human epidermal growth factor receptor 2-positive breast cancer (HER-2 + BC) when used alone or in combination with chemotherapy or with tyrosine kinase inhibitors, so as to aid in rational treatment choices.

Materials and Methods:

An electronic search was conducted on PubMed using the Mesh terms ‘BC’, ‘HER-2 positive’, ‘metastasis BC, ‘trastuzumab’, and ‘safety’. Data from 32 studies regarding AEs were extracted and categorised as trastuzumab + chemotherapy (T+C), trastuzumab biosimilar (Tb), trastuzumab + tyrosine kinase inhibitors+ chemotherapy (T+TKi+C), and trastuzumab + tyrosine kinase inhibitors (T+TKi). The data are presented as the mean percentage of AEs. The statistical comparison was represented by a box and whisker plot of the interquartile range value of AEs.

Results:

AEs related to the gastrointestinal tract, skin, nervous, blood, and lymph were reported to be the most common in T+C, T+TKi+C, and T+TKi. Nausea, vomiting, diarrhoea, constipation, neuropathy peripheral, alopecia, rash, anaemia, leucopenia, raised aspartate transaminase and alanine transaminase were the most common complaints. AEs such as myalgia, nasopharyngitis, hypertension, and ejection fraction decrease was reported to be the most common in Tb.

Conclusion:

This study concluded that biosimilar of trastuzumab is safest for the treatment of HER-2-positive BC. Cardiovascular disorder is often reported in the biosimilar group, but this group has fewer AEs reported as compared with chemotherapy, and tyrosine kinase inhibitors groups related to other systems such as digestive, nervous, and respiratory. The choice of combination is depending on the type of BC and the condition of the patients. The patients must monitor for cardiotoxicity when the biosimilar of trastuzumab is used.

The Elderly and Leisure Activities: A Case Study
Authors: Marques Jacqueline , Teixeira Mónica
Published: May 2022

Studies on the ageing population are increasing in number, aiming to find strategies that allow this life cycle’s phase to be lived with quality. The practice and development of leisure activities is an important factor of life’s quality, since it contributes to a better state of mind and, in the case of older people, it may be a strategy to mitigate the effects resulting from the ageing process. Despite, and according to some studies, the elderly do not give leisure a great importance in their lives, often due to their life history, which did not provide them with good conditions and opportunities to develop these activities. Even for elderly people who have no leisure time habits, the fact is that, when they reach a certain age, these activities can become a structural element of their daily lives. This study aims to ascertain what type – and with which intensity – of leisure and free-time occupation activities the elderly perform, as well as the impact of the pandemic on the performance of these activities. This descriptive research uses a questionnaire as a data collection tool, divided into four parts: the first part involves a set of sociodemographic data; the second part, based on the "Leisure Activities Index" by Rosa Martins (2016), includes a set of nine questions; the third part integrates a question to understand the elderly’s perception of their leisure time use; and, finally, the fourth part includes a set of questions on the impact of the pandemic on the performance of leisure activities. The non-probability convenience sample included a set of 33 older people attending a Day Care Centre and a Home Support Service in central Portugal.

The introduction of Arabic vocabulary into the Malay language resulted in the existence of Malay loanwords derived from Arabic. In addition, the influence of Malay as a mother tongue affects students in mastering Arabic. First language knowledge and experience are often used by students while learning a foreign language. This causes confusion to students in understanding and mastering the structure of Arabic phrases. This is because, the structure of adjective phrases differs between Arabic and Malay. Therefore, this study aims to determine the types of adjective phrases in Arabic and Malay and to study the similarities and differences in both languages based on short stories by Mustafa Lutfi al-Manfaluti and Shahnon Ahmad. The research methodology is through a qualitative approach by document analysis using library research. This study also uses the contrastive analysis approach pioneered by Robert Lado (1957) in his book ‘Lingustic Across Culturse’. This analysis is done systematically by comparing the two languages to determine the similarities and differences in terms of adjective phrases in selected short stories. The findings show that there are similarities and differences of adjective phrases in Arabic and Malay which include elements of single adjective phrases, working phrases as adjective phrases, noun phrases as adjective phrases and conjunctions as adjective phrases.

Language as a living thing is the subject of constant adaptations and it evolves in line with the social changes. Every new situation that humanity faces leads to the creation of new words. This paper deals with the terms used in the newspaper to describe all aspects of the coronavirus situation. The idea is to examine which morphological processes have been applied to create these new terms pertaining to coronavirus. The aim is to determine which morphological processes are currently productive in word formation processes. As the analysis has shown, those are the processes of affixation, compounding and blending and some other processes that will be discussed here. The main focus of this analysis is to determine the most productive word formation process in creating words related to coronavirus nowadays. Also, the goal is to represent certain syntactic features of each process involved in creating new words related to coronavirus pandemic in media.
Hume on The Epistemological Status of Metaphysical Statements
Authors: Tweyman Stanley
Published: May 2022

My paper examines critically the widespread view that Hume confines meaningful propositions to those which are analytic (a priori), and those which are synthetic empirical, thereby rejecting synthetic a priori propositions as meaningful. What I show is that Hume does recognize certain metaphysical synthetic a priori propositions as meaningful, thereby dispelling the traditional view that Hume rejects all synthetic a priori as meaningful.

Investigations into the reactivity, properties, and applications of osmium(IV) tetraaryl complexes have been hampered by their low yielding syntheses from volatile and toxic OsO4 (typically ≤34%). Here we show that known air-stable M(aryl)4 compounds (M = Os, Ru; aryl = 2-tolyl, 2,5-xylyl) can be prepared in ≤73% yields using new, less hazardous (Oct4N)2[MX6] precursors (M = Os, Ru; X = Cl, Br). This approach also facilitates the preparation of Os(mesityl)4 (Os3) for the first time, a complex comprising bulky 2,6-dimethyl substituted aryl ligands, albeit in low yield (5%). To better understand these yield extremes, we track, by synthesizing two additional new complexes with different 2-substituted σ-aryl ligands, a clear relationship between the yields of Os(aryl)4 and ligand steric bulk. Single-crystal X-ray structures of these compounds indicate that the observed yield trend reflects the ease of accommodating aryl substituents into an open pocket that lies directly opposite each M-aryl coordination site. We perform variable-temperature 1H NMR studies of Os3, utilize a "tetrahedricity" metric to assess geometric distortion in Ru(aryl)4 and Os(aryl)4 materials, and calculate cone angle and percentage buried volume metrics to further illustrate and help quantify 𝜎-aryl ligand steric properties. Solution cyclic voltammograms of Os(aryl)4 show that the potentials of their reversible 1−/0 and 0/1+ redox features can be fine-tuned by varying aryl substituents, and that Os3 exhibits an additional 1+/2+ redox event not previously observed in this class of compounds. Taken together, this work helps to advance the potential application of these relatively underexplored organometallic complexes in established and emerging areas of molecular materials science, such as extended molecular frameworks and self-assembled monolayers, where analogous tetraphenylmethane and silane species (M = C, Si) have been frequently targeted.

The outstanding impact of fluorine atom in drug discovery cannot be overestimated. Substantially, the incorporation of the gem-difluoro (CF2) group into organic frameworks is highly sought due to the influence of this unit on physicochemical and pharmacological properties of molecules. Yet, introduction of CF2 moiety into organic structures is a step-intensive preparation, and known approaches are often limited to certain classes of molecules. Development of strategies for a rapid incorporation of gem-difluoro synthon that utilizes inexpensive commercial reagents is highly desirable. In the context of divergency and applicability of such reagents, switchable synthesis can be beneficial to access a wide range of fluorinated compounds. Herein we report a mild and operationally simple protocols to access various gem-difluoro compounds that employs chlorodifloroacetic anhydride (CDFAA) as a low cost and versatile fluoroalkylating reagent. Detailed mechanistic investigations revealed that electron-transfer photocatalysis triggers mesolytic cleavage of a C−Cl bond generating a gem-difluoro carboxy radical. In the presence of alkene molecule, this radical species acts as an efficient and unique bifunctional reagent that, under solvent-controlled reaction conditions, delivers a wide range of gem-difluorinated γ-lactams, γ-lactones, as well as promotes oxy-perfluoroalkylation. These protocols are flow and batch scalable, possess excellent chemo- and regioselectivity, and can be used for the late-stage diversification of biorelevant molecules.

Published: May 2022

Comparisons of observation-based emission estimates with emission inventories for oil and gas production operations have demonstrated that intermittency in emissions is an important factor to be accounted for in reconciling inventories with observations. Most emission inventories do not directly report data on durations of active emissions, and the variability in emissions over time must be inferred from other measurements or engineering calculations. This work examines a unique emission inventory, assembled for offshore oil and gas production platforms in United States coastal waters, which reports production-related sources on individual platforms, along with estimates of emission duration for individual sources. Platform specific emission rates, derived from the inventory, were compared to shipboard measurements made at 72 platforms. The reconciliation demonstrates that emission duration reporting, by source, can lead to predicted ranges in emissions that are orders of magnitude broader than those based on annual average emission rates. Total emissions reported in the inventory for the matched platforms were 20-30% larger than total emissions estimated based on observations. The distributions of emissions were similar, with 75% of platform total emission rates falling between 0 and 49 kg/hr for the observations and between 0.59 and 54 kg/hr for the inventory.
Investigation of the Effectiveness of Aquatic Plants in Filtering Contaminated Water

Published: May 2022

Population increase and rapid urbanization are two major factors for scarcity of clean water in 21st century societies across the world. Modern sewage water treatment plants and filtration systems require a lot of economic and land resources which many “lesser developed countries” do not have, leading to large amounts of raw sewage water being released into the enviornment and a lack of clean water for millions. To fulfil such water demand, the use of aquatic plants, also known as macrophytes, have been used in a constructed wetland which allows for the filtration of contaminated water using natural processes involving wetland vegetation, soils, and their associated microbial assemblages. In the present study, Typha (cattail) and Pontederia crassipes (water hyacinth) have been tested in a simulated constructed wetland to study their effect on pollutants removal efficiency (nitrates, ammonium, pH, and Dissolved oxygen). Results show that both the Typha and Pontederia crassipes were effective in filtering out the aforementioned contaminants through the process of phytoaccumulation. However, there was no clear correlation between Dissolved oxygen levels and time in contact with the macrophyte roots possibly due to environmental factors. A better quantitative understanding of the phytoaccumulation process, such as the limits and plateau points of contaminant uptake is needed to optimize the usage and application of Typha and Pontederia crassipes in practical constructed wetlands.

Here, we established a mechanistic insight into the catalytic production of ammonia from dinitrogen via the combination of samarium diiodide (SmI2) and water in the presence of molybdenum complexes bearing PCP-type pincer ligands as the catalysts. The experimental and theoretical studies revealed that the rate-determining step was the proton-coupled electron transfer (PCET) during the formation of the N–H bond on the molybdenum imide complex at high catalyst concentrations. Additionally, we confirmed that the concentration of the catalyst affected the rate-determining step and the dimerisation step of the catalyst became the rate-determining step at a low catalyst concentration. Thus, we designed PCP-type pincer ligands in which various substituents were introduced at the positions 5 and/or 6, to accelerate the rate-determining PCET reaction and observed that the introduction of electron-withdrawing groups promoted the reaction rate, as predicted by density-functional theory calculations. Finally, the molybdenum trichloride complex bearing a trifluoromethyl group containing PCP-type pincer ligand functioned as the most effective catalyst for producing up to 60,000 equivalents of ammonia based on the molybdenum atom of the catalyst, with a turnover frequency of up to 800 equivalents/Mo·min−1. The amount of ammonia produced via this reaction, as well as its production rate, were approximately one order of magnitude larger than those obtained under the previous reaction conditions. The findings reported herein can contribute to the development of an environmentally friendly next-generation nitrogen fixation system.

Published: May 2022

Niobium pentoxide (Nb2O5) is in the limelight as a negative electrode material for advanced electrical energy storage devices owing to its unique pseudocapacitive behavior. However, its intrinsic poor electronic conductivity restricts its electrochemical performance. In this study, argon-ion bombardment is employed to enhance the interfacial properties of the Nb2O5 negative electrode by introducing highly conductive NbOx (1 ≤ x ≤ 2) species on the electrode surface. The NbOx surface architecture fosters significant improvements in the reversible capacity and rate performance of the argon-ion bombarded electrode than pristine electrodes. Detailed analysis reveals that introducing the surface NbOx layer promotes charge transfer at the electrode surface and breaks the limitations of charge transfer resistance. The result provides a pathway to enhance intrinsic shortness of conductivity and to establish surface modification simultaneously via a simple argon-ion bombardment method, thus achieving the improved electrochemical performance of Nb2O5 and serving as an expedient strategy for augmenting electrode materials for advanced energy-storage applications.

Published: May 2022

Control of the association behavior by the molecular design is one of the most essential benefits in artificial supramolecular systems. 1,14-Dianilinotripyrrin has recently emerged as a novel conjugated molecule which forms a double helix in non-polar solvents with the aid of multiple interstrand hydrogen bonding interactions. In this work, we investigated the substituent effects at the 5,10-positions of tripyrrin on their association dynamics. This study illuminated two key findings; 1) electronic tuning by the para-substituents reduce the entropic costs thereby slightly improve the association constants, and 2) ortho-substituents force the tripyrrin core to be relatively planar, which significantly decrease the association constant due to less feasible π-stacking.
Long-term stability of ferri-/ferrocyanide as an electroactive component for redox flow battery applications: On the origin of apparent capacity fade

Published: May 2022

We assess the suitability of potassium ferri-/ferrocyanide as an electroactive species for long-term utilization in aqueous organic redox flow batteries. A series of electrochemical and chemical characterization experiments was performed to distinguish between structural decomposition and apparent capacity fade of ferri-/ferrocyanide solutions used in the capacity-limiting side of a flow battery. Our results indicate that, in contrast with previous reports, no structural decomposition of ferri-/ferrocyanide occurs at tested pH values as high as 14 in the dark or in diffuse indoor light. Instead, an apparent capacity fade takes place due to an electroless reduction of ferricyanide to ferrocyanide, via electroless oxygen evolution reaction. We find that this parasitic process can be further exacerbated by carbon electrodes, with apparent capacity fade rates at pH 14 increasing with an increased ratio of carbon electrode surface area to total amount of ferricyanide in solution. Based on these results, we report a set of operating conditions that enables the cycling of alkaline ferri-/ferrocyanide electrolytes, and demonstrate how apparent capacity fade rates can be engineered by the initial cell setup. If protected from direct exposure to light, the chemical stability of ferri-/ferrocyanide anions allows for their practical deployment as electroactive species in long duration energy storage applications.
