Semi-commutativity of graded rings and graded modules
Authors: Bataineh Malik , Refai Mashhoor , Abu-Dawwas Rashid , Al-Zoubi Khaldoun
Published: November 2022

A ring R is said to be semi-commutative if whenever a, b ∈ R such that ab = 0, then aRb = 0. In this article, we introduce the concepts of g−semi-commutative rings and g−N−semi-commutative rings and we introduce several results concerning these two concepts. Let R be a G-graded ring and g ∈ supp(R, G). Then R is said to be a g−semi-commutative if whenever a, b ∈ R with ab = 0, then aRgb = 0. Also, R is said to be a g − N−semi-commutative if for any a ∈ R and b ∈ N(R) ⋂ Ann(a), bRg ⊆ Ann(a). We introduce an example of a G-graded ring R which is g − N-semi-commutative for some g ∈ supp(R, G) but R itself is not semi-commutative. Clearly, if R is a g−semi-commutative ring, then R is a g − N−semi-commutative ring, however, we introduce an example showing that the converse is not true in general. Several results and examples are investigated. Also, we introduce the concept of g − NE−semi-commutative rings and we introduce several results concerning g−NE−semi-commutative rings. Let R be a G-graded ring and g ∈ supp(R, G). Then R is said to be a g−NE− semi-commutative ring if whenever a ∈ N(R) and b ∈ E(R) such that ab = 0, then aRgb = 0. Clearly, g−semi-commutative rings are g −NE−semi-commutative, however, we introduce an example ...

Published: November 2022

Klebsiella is a pathogen that causes a significantly high number of community-acquired and hospital-acquired infections, with infections being one of the leading causes of death in ICU patients worldwide due to increasing antibiotic-resistance and a lack of therapeutic options. A total of 230 Klebsiella spp. were collected from various clinical samples. After initial identification, the drug-resistant strain was subjected to standard Clinical Laboratory and Standards Institute methods such as Kirby–Bauer disc diffusion. All isolates were screened and confirmed for ESBL/AmpC β-lactamase/carbapenemase production. The isolated Klebsiella spp. were found to be K. pneumonia (89%), K. oxytoca (6.5%), and K. aerogenes (4.5%). Among the 230 isolates, 80 (34.7%) isolates were found to be ESBL producers via screening; of these, 53 (23.5%) were verified by a confirmatory test. Moreover, 115 isolates (50%) were screened as AmpC producers; of these, 23 isolates (10%) were verified by a confirmatory test. Carbapenemase producers accounted for 69 (30%) isolates, identified by screening; 25 (10.86%) were verified by a confirmatory test. ESBL producers accounted for the majority of Klebsiella spp. isolates, followed by carbapenem and AmpC producing strains.

Published: November 2022

The interest in many traditional natural products is increasing. Natural products continue producing bioactive agents owing to the remarkable available chemical diversity. They were evaluated as prospective therapeutic candidates for the treatment of human and animal infectious diseases. Euphorbiaceae, the spurge family, holds a significant place in the domain of plant families, with scientific evidence of antiviral, antibacterial, anticancer, cytotoxic and antitumor properties. In this regard, the current study intends to investigate the antibacterial, antifungal, antiviral and cytotoxic properties of Euphorbia greenwayi var. greenwayi Bally & S. Carter. The dried aerial parts of E. greenwayi var. greenwayi Bally & S. Carter were used, then extracted with 70% ethanol, solvent was distilled off till dryness. The antimicrobial activity of the extract and both MIC and MBC were evaluated against one strain of Gram-positive bacteria: Staphylococcus aureus ATCC9144; four strains of Gram-negative bacteria: Klebsiella pneumonia ATCC10031, Escherichia coli ATCC10536, Salmonella typhi ATCC14028, Pseudomonas aeruginosa ATCC9027and yeast: Candida albicans ATCC10231. The antiviral activity of hydroalcoholic extract against Rotavirus infection was determined as well as the cytotoxic properties. The antibacterial examination revealed potential activity of the hydroalcoholic extract against all tested species with the inhibition zone ranged from 14.7 to 29.7 mm. The highest activity was against S. aureus and C. albicans. MIC and MBC results proved that the extract is potentially bacteriostatic and bactericidal agents against both Gram-positive and Gram-negative bacteria and against the tested yeast. Also, the extract has the ability to prevent Rotavirus attachment with the cell host. This research revealed that the hydroalcoholic extract of aerial parts of E. greenwayi var. greenwayi Bally & S. Carter has significant antimicrobial potential that can be implemented in different pharmaceutical formulations.

Authors:   Latvijas Universitāte, Lipša Ineta
Published: November 2022

Izmantojot biogrāfisko pieeju, rakstā tiks parādīta valsts sankcionētā vardarbība pret sievietēm 1905.–1907. gada revolūcijā. Matildes Krēgeres (1880–?) un Emmas Rigertes, dz. Lietuvietes, (1879–?) stāsti ir pagaidām vienīgie zināmie detalizēti vēstītie sieviešu pieredzes gadījumi. Abu pierakstīšanu veicināja biedrības “Piektais gads” 1926. gada aicinājums aktīvajiem revolūcijas dalībniekiem iesniegt anketas par pieredzēto. 1930.–1931. gadā daži autori latviešu presē pieminēja seksuālo vardarbību, ko soda ekspedīciju karavīri īstenoja pret sievietēm, tomēr citi preses izdevumi sabiedrībā dominējošo patriarhālo priekšstatu dēļ neizmantoja šķietamo aicinājumu vēstīt par tādām pieredzēm. 1905.–1907. gada revolūcijas piemiņas institucionalizēšanas iniciatore bija Latvijas Sociāldemokrātiskā strādnieku partija, bet pēc 1934. gada, kad autoritārā režīma valdība likvidēja partijas, vairs nebija politiskā spēka, kas varētu pievērst uzmanību fiziskā un seksuālā vardarbībā cietušo sieviešu pieredzei.
Latvia as a partner in the political security system of Western democracies in the early 1920s: Latvia’s relations with Great Britain, the United States and Germany
Authors:   University of Latvia, Krēsliņš Uldis
Published: November 2022

For the new states that emerged as a result of the First World War, ensuring the internal political security in the early 1920s was a fundamentally important issue. In the case of Latvia, potential security threats were exacerbated by the country’s geopolitical position – a direct border with Soviet Russia – which made Latvia a protective barrier against the spread of the Communist movement. The aim of the study is to characterize Latvia’s role in the political security system of Western democracies in the early 1920s based on the materials of the Latvian security service, focusing on Latvia’s relations in the field of political security with three Western democracies – United Kingdom, the United States and Germany.

Self-efficacy beliefs of English teachers from a non-educational background in the Indonesian context
Authors: Noviani Stella , Kuswandono Paulus
Published: November 2022

This research investigates how English teachers with a non-English educational background demonstrate their self-efficacy beliefs on the technological pedagogical content knowledge (TPACK) toward their professional practices. The data was obtained from 18 teachers from a non-English educational background in formal and informal Indonesian education settings. Those teachers undertook strategies to develop the technological pedagogical content knowledge (TPACK) while managing their self-efficacy beliefs. Employing a mixed-method research approach, this study gathered the data using closed-ended and open-ended questionnaires, individual interviews, and in-depth interviews. Responses revealed that 18 participants completed a 5-item Likert-type survey measuring the level of teachers’ TPACK self-efficacy. The survey measures the three major aspects of TPACK mean value for teachers’ technological knowledge (TK) (X ̅=23.55) and pedagogical knowledge (PK) (X ̅=19.55), both of which are relatively higher than the value of the content knowledge (CK) (X ̅=16). The dominant factor affecting the high percentage in those two aspects emanates from the teachers’ persistent accounts that they need to be independent in learning while constantly updating their knowledge. This research also discusses the suggestion for future research studies for developing teachers’ TPACK self-efficacy.

CONSTRUCTION PROJECT DELAY DUE TO THE COVID-19 PANDEMIC
Authors: N Zanuar S. , S.R Mohd Nasir
Published: November 2022

The COVID-19 pandemic that hit the whole world has harmed several industries including the construction industry. It has caused the operation of the construction industry had to be stopped for a while because the construction industry is reported to be one of the industries with a high risk of COVID-19 virus transmission. Due to that, many construction projects were delayed as a result of series of movement control orders by the government. The purpose of this study is to identify the main contributor factors to project delay due to Covid-19. In addition, this study identifies the mitigation actions to overcome the delays for building construction project in Malaysia. Quantitative method was used and online questionnaire survey were distributed to the target respondents involves clients, consultants, and contractors. The research area covers the conurbation of Klang Valley, Great Penang, and Iskandar city as these areas contain about a third of the overall country’s population (Chin et al., 2019). In addition, the number of construction companies as at March 2021 located in Klang Valley, Johor and Penang are 1672, 653 and 323 respectively (CIDB, 2021). Relative Important Index (RII) and correlation analysis were used to analyse the data obtained from the survey. The finding of this study identifies the main factors contribute to delay during COVID-19 pandemic are delay in material delivery; delay in decision making by the consultants; delay in revising and approving document; and unclear of Standard of Procedure (SOP) instructions by the government. As a result, project is suffering with cost overrun and the loss of skilled and unskilled labours. In order to overcome delay, the findings suggest that proper planning and rescheduling; systematic and clear communication; getting help from government aid and completing worker’s overdue payment are among the mitigation actions proposed by the respondents. The finding of this study shed light in preventing unnecessary delays in construction project due to the unpredictable pandemic by identifying the factors and impact of delays to improve the awareness of pandemic effect to the construction project. The outcome of the research study can be used as a guidance to help the construction practitioners especially for the clients, consultants, and contractors to monitor and act in the future construction activities to avoid unnecessary project delays when facing unpredictable pandemic in the future.

Hybrid Plasma-Thermal System for Methane Conversion to Ethylene and Hydrogen
Authors: Liu Rui , Hao YIngzi , Wang Tong , Wang Li , Bogaerts Annemie , Guo Hongchen , Yi Yanhui
Published: November 2022

By combining dielectric barrier discharge plasma and external heating,
we exploit a two-stage hybrid plasma-thermal system (HPTS), i.e., a
plasma stage followed by a thermal stage, for direct non-oxidative
coupling of CH4 to C2H4 and H2, yielding a CH4 conversion of ca. 17 %.
In the two-stage HPTS, the plasma first converts CH4 into C2H6 and C3H8,
which in the thermal stage leads to a high C2H4 selectivity of ca. 63 %
by pyrolysis, with H2 selectivity of ca. 64 %.

Published: November 2022

A comparative research on the impact of organic amendments on the soil characteristic and uptake of heavy metals, micro and macroelements of Odontarrhena chalcidica has been carried out. Experiments have been implemented in controlled conditions. The serpentine soil used in this experiment was sampled from the vicinity of the village Kazak, Bulgaria. The pot experiment was a randomized complete block design containing 9 treatments and three replications (27 pots). The treatments consisted of a control (no organic meliorants), and compost, vermicompost, biochar and activated carbon (added at 2.5% and 5.0%, respectively, recalculated based on dry soil weight). The application of organic additives to the soil influences the physicochemical properties and leads to an increase in organic matter and the content of macroelements (P, K, Ca and Mg) and trace elements (Fe, Mn, Zn) in the soil. The application of organic additives to the soil affects the uptake of Ni, micro and macroelements by Odontarrhena chalcidica. Plant biomass increased significantly, and there was a clear correlation between the amount of supplement applied and the increase in biomass. Organic additives had a positive effect on yield, influenced by the type of additive and dose. Ni yield was 3 times higher in the variants with 5% compost and 2.5% vermicompost input. The application of biochar resulted in a twofold decrease in Ni yield, while the application of activated carbon resulted in a marginal increase.

Published: November 2022

Tests in in vitro conditions with ethanol extracts from the radix of Berberis vulgaris and the flower twig of Tamarix tetrandra prepared by the method of maceration were performed with two economically important plant pathogens such as Monilia laxa and Phytophthora capsici. The received results show that the extracts from the radix of the common barberry (Berberis vulgaris) are able to fully block the growth of mycelium of Monilia laxa at 0.5 % (m/v) concentration during the entire period of testing (14 days). However, the effectiveness of the tested plant extracts towards Phytophthora capsici was significantly lower and Tamarix tetrandra expressed better action.

Published: November 2022

This article reviews the role and place that wine tourism holds in the specialization of the different tourist regions in the country according to the current Concept for Touristic Zoning of Bulgaria (2015). It was clarified for which of the tourist regions wine tourism is the main, respectively complementary type of tourism. Along with that, a comparison was made between the tourism zoning adopted in our country and one of the viticultural zonings which reveals five viticultural regions. It was established that wine tourism was listed as the main or a complementary type of tourism for four out of five identified wine - growing regions. An attempt has been made to explain the absence of wine tourism both in the main and in the additional specialization of Varna and/or Burgas Black Sea tourist regions which are part of the Eastern ("Black Sea") viticultural region of Bulgaria.

As a cooling device for cooling the human body, the cooling garment has been used in many fields. This study was guided by the theory of traditional Chinese medi?cine, an acupoints-meridians cooling vest (AMCV) system was designed to cold and stimulate the acupoints and meridians of the human body. Three healthy male subjects were recruited to participate in the test, with AMCV or without AMCV (CON), in a high temperature environment (37 ?1?, 46 ?3% RH) to simulate standing on duty for 50 minutes. The results showed that the skin temperature, Tskin, with AMCV was lower than that with CON (p < 0.05). The average Tskin with AMCV decreased by 0.45 ? more than that with CON (p < 0.05). The average tympanic temperature, Tty, with AMCV was lower than that with CON (p < 0.05). Howev?er, the average Tty with AMCV decreased by 0.05? more than that with CON (p < 0.05). The heart rate with AMCV was significantly lower than that with CON (p < 0.05). The average thermal sensation and thermal comfort with AMCV were better than those with CON in the corresponding period (p < 0.05). The results indicated that AMCV could improve thermal comfort and reduce the heat strain of the human body in a high temperature environment.

Glucokinase (GK, gene symbol GCK) maturity-onset diabetes of the young (MODY) is caused by heterozygous inactivating mutations in GK and impaired glucose sensing. We investigated effects of dorzagliatin, a novel allosteric GK activator, on insulin secretion rates (ISRs) and β-cell glucose sensitivity (βCGS) in GCK-MODY and recent-onset type 2 diabetes. In a double-blind, randomized, crossover study, 8 participants with GCK-MODY and 10 participants with type 2 diabetes underwent 2-h 12 mmol/L hyperglycemic clamps following a single oral dose of dorzagliatin 75 mg or matched placebo. Effects of dorzagliatin on wild-type and mutant GK enzyme activity were investigated using an NADP+-coupled assay with glucose-6-phosphate dehydrogenase in vitro. In GCK-MODY, dorzagliatin significantly increased absolute and incremental second-phase ISRs versus placebo but not the acute insulin response. Dorzagliatin improved βCGS in GCK-MODY with an upward and leftward shift in ISR-glucose response. Dorzagliatin increased basal ISRs in type 2 diabetes, with smaller changes in second-phase ISRs versus GCK-MODY. In vitro, dorzagliatin directly reduced the glucose half saturation concentration of wild-type GK and selected GK mutants to varying degrees. Dorzagliatin directly restored enzyme activity of select GK mutants and enhanced wild-type GK activity, thereby correcting the primary defect of glucose sensing in GCK-MODY.
