that causes dental caries.
Authors: Mojaz Tawfeeq Ghafar Asalah , Naji Dahham Shaymaa
Published: November 2023

The study included 147 oral swabs collected from dental caries patients between
October 2020 and January 2021. The culture results on the isolation medium
showed that 73 samples, 49.7% of the total samples, showed positive growth, while
74 samples or 50.3%, showed no bacterial growth. p . gingivalis isolates produced
hemolysin and biofilm formation by 100%. Their ability to produce B-lactamase
was decreased, and the percentage of isolates produced was 42.5%, and the percentage of protease-producing isolates was 20.5%. As for the enzyme lipase and
urease, all isolates could not produce them. The results showed that all bacterial
isolates were resistant to all the antibiotics used, namely Piperacillin - Ciprofloxacin - Levofloxacin - Carbenicillin - oxytetracycline - Azithromycin - Meropene -
Norfloxacin at 0%, 0%, 60.3%, 100%, 0%, 60.3%, 60.3%, 9.6%, respectively. Extracts of cloves, pomegranate peel and miswak (aqueous and alcoholic) were used
at four concentrations of 75, 100, 150 and 200 mg/ml, and they showed different
inhibitory activities against the studied bacteria depending on the concentration.
200 mg/ml is among the most effective inhibitors, especially alcoholic extracts.
For these plants, the alcoholic extracts of pomegranate peel, cloves and toothpicks
recorded the highest inhibitory activity, with 52, 48 and 25 mm diameters, respectively. The lowest inhibitory activity of the alcohol extract was a concentration of
75 mg, and the highest inhibitory activity was observed against pomegranate peels
with a diameter of 25 mm cloves and toothpicks with a diameter of 22 and 8 mm,
respectively.

Published: November 2023

The specific nature of the current socio-economic and geopolitical situation predetermines the urgent need to update the mechanisms for the implementation of Russian national projects and development programs. One of such programs is the achievement of the Sustainable Development Goals until 2030, including in the construction industry. Despite the significant interest of the authors to this problem, some of its key aspects have not yet been studied. The achieved scale of participation of construction market companies in the Sustainable Development Agenda has not been determined. Issues concerning the prospects and main mechanisms for achieving the Sustainable Development Goals in construction by 2030 have not been studied. The purpose of this study is to determine the prerequisites and prospects for the transition of Russian construction market companies to a sustainable development model and assess the features of management of this process. In addition to well-known general scientific methods and generalization of materials from scientific publications, the research methodology includes applying the methods for aggregating numerical data and statistical analysis.The article formulates two theoretical provisions that contribute to the conceptual foundations of sustainable development. The specificity of the ratio of the components of sustainable development in the construction industry is determined and a classification of regulatory legal acts is proposed. The conclusion about the potential for sustainable development of companies in the construction market is of applied significance. The positive assessment of the regulatory framework as the main mechanism of management of sustainable development of the construction industry is substantiated.

Published: November 2023

The main factors accompanying the processes of reinforcement of steel structures under operational load and those reducing its effectiveness (initial stresses, deformability of elements under load, the presence of ceiling seams, etc.) are described. The proposed method of strengthening the bending elements on the example of steel I-beams is analyzed. Reinforcement is assumed to be a strip welded to the lower shelves of the I-beams through intermediate U-shaped elements. This strip, therefore, plays a kind of tightening role. The method allows solving the problem of different curvature of reinforced and reinforcing elements, avoiding overlapping of ceiling joints and performing most of the welding joints in factory conditions.

Authors: Narayanaswamy Sharadamma , Hanumegowda Lekhana , Sadhasivam Jayashree , Rangappa Nagesh Babu
Published: November 2023

Tannases or Tannin acyl hydrolases (EC 3.1.1.20) are a family of esterases that catalyze the hydrolysis of ester and depside bonds present in hydrolyzable tannins to release gallic acid. Industrial applications of tannase in food, brewing, chemical, pharmaceutical, and bioremediation, have made it one of the most important enzymes in research. The aim of the present study focused on the degradation of tannic acid by novel bacterial tannase isolated from slaughterhouse waste-enriched soil. Soil containing ruminant microflora is cultured on MSM containing tannic acid. Among four bacterial isolates, a potent strain was cultivated for identification which are then analysed for biochemical characterization and physiological characterization. Bacteria use tannic acid as the sole carbon source for growth and showed maximum growth at 0.6%. The morphology of the isolate shows that it contains gram-negative rods that are nonmotile and capsulated. Based on 16S rRNA and phylogenetic analysis, the isolate was confirmed as Enterobacter hormaechei Z8b-60. Tannase production from bacteria was confirmed by a novel, sensitive plate assay by observing the zone of clearance around colonies and also by dye binding method using methyl gallate as substrate. During the study, TLC and HPLC were performed to analyze the accumulated gallic acid and other metabolites. Intracellular tannase production amplified from 14.98 U/mL to 102.7 U/mL as tannic acid concentration increases from 0.4% to 1.0%, respectively.

Global warming has become an issue for the whole world until now. The cause of global warming is air pollution produced by engine fuels from various automotives that can produce carbon dioxide. This encourages people to be more concerned about the environment, including the automotive industry. The rise of the movement to care for the environment encourages automotive companies to make electric car products which can be a solution to reduce pollution. In recent years, electric cars have started to enter the market in Indonesia. However, this is not well received by the Indonesian people. This is related to the low purchase intention of the electric car itself. The purpose of this study was to determine empirically the effect of attitude, subjective norm, perceived behavioral control, and price sensitivity on consumer purchased intention of electric cars in Jakarta. This study uses data collected from 153 respondents who are people who at least are undergoing undergraduate studies and have knowledge of electric cars in Jakarta. The data was obtained by distributing an online questionnaire in the form of a google form through social media. The data is then processed using SmartPLS 3.2.9 software. The results of this study are attitude, subjective norm, and price sensitivity have a positive and significant influence on the purchase intention of electric cars in Jakarta.

The technology company GoTo has listed its share securities on the Indonesian capital market. GoTo has listed shares with a series or Multiple Voting Shares (MVS) scheme. The Financial Services Authority (OJK) has issued POJK, which regulates MVS. MVS gives rise to shares with voting rights that are different from other shares. This system is known as the dual-class voting system (DCVS). This study aims to discuss how to protect the interests of retail investors who have investments in companies that have MVS. This research uses legal normative. This study concludes that MVS must have a specific validity period, except State-Owned Enterprises (BUMN). The government must own SOEs that influence many people's lives with dual-colored shares. These MVS shares do not have voting rights but still, have the advantage of dividends. The purpose of MVS is for shareholders to protect the company's long-term interests. The government owns Dwiwarna shares intending to safeguard the interests of the national economy. MVS or DCVS affects the long-term running of the company's business to remain appropriate and avoid a hostile takeover.

Implementasi Desentralisasi Fiskal dalam Kebijakan Transfer Dana ke Daerah Pada Realisasi Anggaran Pendapatan dan Belanja Negara Tahun 2021
Authors: Hardiana Diah Riski
Published: November 2023

Fiscal decentralization has been officially implemented in Indonesia since the beginning of the reform, to be precise since January 2001, and implemented to create regional self-reliance. With the regional autonomy policy and fiscal decentralization, every region in Indonesia receives a large delegation of authority. In 2020, the Covid-19 Pandemic rocked the Indonesian economy. Economic growth continued to decline and had a negative impact on the people's economy, in addition to influencing the Transfer to Regions and Village Fund (TKDD) policies. Regional Governments are given the authority to prioritize the use of budget allocations for specific programs (refocusing), change allocations, and use the Regional Revenue and Expenditure Budget (APBD). Merilee S. Grindle's theory of implementation is the rationale for this research, focusing on aspects of the desired degree of change, location of decision-making, program implementation, and level of compliance and responsiveness. Regarding the desired degree of change, regional governments must reallocate budgets and refocus programs according to the central government's regulations. Aspects of program implementation, budget reallocation, and refocusing programs in several regions were successfully carried out. Aspects of the location of decision-making appropriate policies by prioritizing the health, social, economic, and regional financial sectors. While the aspects of compliance and responsiveness show that the policy has yet to be realized optimally, several problems were found in its implementation.

In this paper, we demonstrate a deep reinforcement learning method to train a policy of fixed-wing aircraft agents to leverage hand-scripted tactics to exploit force concentration advantage and within-team coordination opportunities to destroy, or destroy, as many opponent team members as possible while preventing teammates from being attrited. The efficacy of agents using the policy network trained using the proposed method outperform teams utilizing only one of the handcrafted baseline tactics in [Formula: see text]-vs-[Formula: see text] engagements for [Formula: see text] as small as two and as large as 64 as well as learner teams trained to vary their yaw rate actions, even when the trained team’s agents’ sensor range and teammate partnership possibility is constrained.
Time- and Energy-Saving Potentials of Efficient Urban Air Mobility Airspace Structures
Authors: Preis Lukas , Husemann Michael , Shamiyeh Michael
Published: November 2023

Novel electric propulsion technology has given rise to thinking about urban air mobility in a new way with its expected high degree of operational flexibility. The designs of electric vertical takeoff and landing configurations are determined by their mission profile, which we found to be oversimplified at many points in the current scientific literature. There is a gap of understanding in how mission profiles impact travel time and energy demand. In this paper, we review various mission designs, formulate a five-segment flight profile (including vertical ascent, climb, cruise, descent, and vertical approach), and apply it on a fleet level of up to 200,000 urban air mobility trips. The demand data originate from the Upper Bavaria region study, OBUAM. In a sensitivity study, we vary the cruise altitude, the height of the vertical flight segments, and the climb and descent angles for two vehicle configurations: a fixed-wing tilt-rotor concept, and a multicopter concept. The main findings for the fixed-wing concept are that the height of the vertical flight segments and the cruise altitude should be as low as possible, and small climb angles (below 7 deg) should be avoided. The multicopter concept, however, is penalized by fast forward flight while being comparatively insensitive to both the cruise altitude and height of the vertical flight segments. Furthermore, we found a tradeoff between time- and energy-optimal flights with the a energy-optimized climb/descent angle at around 10 deg.
Gendered Understanding and Experiences of Sexual Harassment: Informing a Policy Framework for Higher Education Institutions
Authors: Nunlall Reema , Steyn Francois
Published: November 2023

Sexual harassment policies in South African higher education institutions show variations in focus and content. In this study, we set out to determine students’ understandings and experiences of sexual harassment with the broader aim of informing a framework that higher education institutions could use to strengthen their sexual harassment policies. A total of 640 (of a potential 2 222) students completed an online survey that, among other things, incorporated the Sexual Experience Questionnaire. Non-parametric procedures were used to identify significant gender differences and effect sizes in students’ understandings and experiences of sexual harassment. More female students experienced some form of sexual harassment, and they were more likely to recognise different types of verbal sexual harassment (possibly because they present a broader definition of harassment). The female students appeared less tolerant of harassment behaviour, but they were significantly more hesitant to report sexual harassment than the male students. In addition, the female students were less likely to consider themselves familiar with the guidelines on reporting incidents of sexual harassment and they were more likely to feel that perpetrators get away with harassment behaviour than the male students. Both male and female students indicated that sexual harassment is more likely to occur between student groups than between students and lecturers. The male and female students expressed strong support for the proposed policy components, including defining sexual harassment, procedures for reporting and disciplinary sanctions for sexual harassment.

Notocupes is a speciose genus of Mesozoic Archostemata, currently including 69 species. Due to its distinct morphological heterogeneity and polyphyly it is advised to split Notocupes into four genera based on full body imprints: Notocupes Ponomarenko, 1964, Rhabdocupes Ponomarenko, 1966, Conexicoxa Lin, 1986, stat. resurr. and Brachilatus Strelnikova et Yan, gen. n. The genus Zygadenia Handlirsch, 1906 is proposed for isolated elytra, morphologically similar to those of four aforementioned genera. Notocupes patulus is transferred to Odontomma Ren et al., 2006 as O. patula (Ponomarenko, 1985), comb. n. Individual characters, such as body cuticular tuberculation are discussed in detail as a promising diagnostic feature to separate genera and possibly also species. The expanded diagnoses for five genera and keys to species of these genera are given. New combinations are proposed for thirty-seven species.

A review of eight species of the genus Platydracus Thomson, 1858 inhabiting the Russian Far East is given. Two species are recorded for the fauna of Russia for the first time: P. inornatus (Sharp, 1874) from Primorskii krai and Khabarovskii krai and P. vicarius (Sharp, 1889) from Jewish Autonomous oblast and Primorskii krai. P. mortuorum (Bernhauer, 1912) is new for the fauna of Khabarovskii krai and P. demissus (Müller, 1925) is new for the fauna of Amurskaya oblast. A key to seven species of the genus Platydracus of the Russian Far East fauna is provided.

Photographs of the types of two problematic species C. nigritulus and C. venustulus are included, as well as a photo of the holotype of C. fulvohirsutus Pic, 1904. References are given to the original publications of all names, as well as to their references in the literature. A key is presented to distinguish between the three species. Each species is briefly described with a set of photographs of specimens from various parts of the range.
Classical imaging in cerebral folate transport deficiency
Authors: Mahal Sayani , Pamnani Jaya , Parakh Manish , Tiwari Sarbesh
Published: November 2023

Cerebral folate transport deficiency is an inherited disorder with late infantile-onset caused by nonsense mutations in the folate receptor 1 gene coding for folate receptor alpha. We report a case of a 4-year-old female child, who presented with global neurodevelopmental regression with onset at 15 months of age with an electroencephalogram showing poorly modulated polymorphic delta sleep background. Based on the clinical features, age of onset, and imaging findings, the possibility of cerebral folate transport deficiency (OMIM#613068) was considered. Targeted gene sequencing confirmed the diagnosis.

Published: November 2023

This study aimed to examine the effect of adding KOH, Na2CO3, and Carboxymethyl Cellulose additives on the physical properties of the mud, as well as the optimal additive for sludge production. The preparation of the basal sludge involved the addition of 22.5 grams of bentonite, 350 millilitres of distilled water, and 10 grams of Barite as a constant variable. Then it stated 0.5 variations of the Na2CO3 additive; 1.5; 3 grams, KOH 0.5; 1.5; and 3 grams, and Carboxymethyl Cellulose 3; 6; and 9 grams. A physical property measurement involving density was conducted. Samples were evaluated for Plastic Viscosity and Yield Point at 300 and 600 rpm dial speeds. After 30 minutes of filter press compression, the filtration loss, mud cake, and pH were measured. The results indicate that the KOH additive decreases Yield Point by 8.6 lb/100ft2 and increases Filtrate Loss by 5.8 mL and sediment pH by 11.12 points. The additive Na2CO3 then causes a reduction in Filtrate Loss of 10.4, 8.8, 7.6 mL and an increase in Plastic Viscosity. While Carboxymethyl Cellulose can increase Plastic Viscosity by 7; 13; 55 cP, Gel strength by 4; 6; 40 Lb/100 ft2, and Filtrate Loss by 10; 8; 7.6mL. Carboxymethyl Cellulose is the additive that has the most significant effect on the physical properties of the mud because it can affect Plastic Viscosity, Gel Strength, Yield Point, and Filtrate Loss so that the soil can approach API 13A Standards. The optimal amount of Carboxymethyl Cellulose should be added at a mass of 6 grams, or 13 cP.
Characterization of Na+currents regulating intrinsic excitability of optic tectal neurons
Authors: Thompson Adrian C , Aizenman Carlos D
Published: November 2023

Developing neurons adapt their intrinsic excitability to maintain stable output despite changing synaptic input. The mechanisms behind this process remain unclear. In this study, we examinedXenopusoptic tectal neurons and found that the expressions of Nav1.1 and Nav1.6 voltage-gated Na+channels are regulated during changes in intrinsic excitability, both during development and becsuse of changes in visual experience. Using whole-cell electrophysiology, we demonstrate the existence of distinct, fast, persistent, and resurgent Na+currents in the tectum, and show that these Na+currents are co-regulated with changes in Navchannel expression. Using antisense RNA to suppress the expression of specific Navsubunits, we found that up-regulation of Nav1.6 expression, but not Nav1.1, was necessary for experience-dependent increases in Na+currents and intrinsic excitability. Furthermore, this regulation was also necessary for normal development of sensory guided behaviors. These data suggest that the regulation of Na+currents through the modulation of Nav1.6 expression, and to a lesser extent Nav1.1, plays a crucial role in controlling the intrinsic excitability of tectal neurons and guiding normal development of the tectal circuitry.
