Authors: Escolano-Pérez Elena , Romero-Galisteo Rita Pilar , Rodríguez-Medina Jairo , Gálvez-Ruiz Pablo
Published: August 2022

Objective

Many university students have difficulties in adapting to autonomous learning due to executive functioning deficits. In the Spanish university context, there is a lack of reliable validated instruments for the evaluation of executive functioning. In this sense, the aim of this research is to present the process of adaptation and validation of the Amsterdam Executive Function Inventory (AEFI) for the evaluation of executive functioning in the Spanish context.

Methods

This study integrates two sequential processes: questionnaire translation and back-translation, and evaluation of the psychometric properties (exploratory and confirmatory factor analysis were conducted), reliability, validity and multigroup analysis to identify factorial invariance. An online questionnaire was used for data collection and R package lavaan software was administered to a sample of 519 first-year university students (270 females and 249 males).

Results

The exploratory factor analysis evidenced an interna structure of three factors with adequate internal consistency (Cronbach’s alpha higher than 0.70), endorsed in the confirmatory factor analysis that indicated an adequate goodness-of-fit-indexes for the model. The composite reliability showed values between 0.74 and 0.82, and the convergent (average variance extracted values ranged from 0.50 to 0.61) and discriminant validity were adequate. A multigroup-analysis showed the invariance factorial through the difference in the RMSEA, CFI and TLI index, performed both in the model comparison according to gender and academic disciplines.

Conclusion

The AEFI adapted for Spanish has practical implications for the management of university students, as it can facilitate the improvement of university policies designed to foster the development of executive functions, specifically in first-year students.

Rational use of medicine (RUM) for all medical conditions is crucial in attaining quality of healthcare and medical care for patients and the community as a whole. However, the actual medicine use pattern is not consistent with that of the World Health Organization (WHO) guideline and is often irrational in many healthcare setting, particularly in developing countries. Thus, the aim of the study was to evaluate rational medicine use based on WHO/International Network of Rational Use of Drugs (INRUD) core drug use indicators in Eritrean National and Regional Referral hospitals. A descriptive and cross-sectional approach was used to conduct the study. A sample of 4800 (600 from each hospital) outpatient prescriptions from all disciplines were systematically reviewed to assess the prescribing indicators. A total of 1600 (200 from each hospital) randomly selected patients were observed for patient indicators and all pharmacy personnel were interviewed to obtain the required information for facility-specific indicators. Data were collected using retrospective and prospective structured observational checklist between September and January, 2018. Descriptive statistics, Welch’s robust test of means and Duncan’s post hoc test were performed using IBM SPSS (version 22). The average number of medicines per prescription was 1.78 (SD = 0.79). Prescriptions that contained antibiotic and injectable were 54.50% and 6.60%, respectively. Besides, the percentage of medicines prescribed by generic name and from an essential medicine list (EML) was 98.86% and 94.73%, respectively. The overall average consultation and dispensing time were 5.46 minutes (SD = 3.86) and 36.49 seconds (SD = 46.83), respectively. Moreover, 87.32% of the prescribed medicines were actually dispensed. Only 68.24% of prescriptions were adequately labelled and 78.85% patients knew about the dosage of the medicine(s) in their prescriptions. More than half (66.7%) of the key medicines were available in stock. All the hospitals used the national medicine list but none of them had their own medicine list or guideline. In conclusion, majority of WHO stated core drug use indicators were not fulfilled by the eight hospitals. The results of this study suggest that a mix of policies needs to be implemented to make medicines more accessible and used in a more rational way.

Published: August 2022

Cervical cancer (CC) screening can detect the cancer early but is underutilized, especially among the developing countries and low- to middle-income countries. Electronic health (e-health) has the potential for disseminating health education and is widely used in the developed countries. This systematic literature review investigates the effectiveness of e-health intervention for improving knowledge of CC and the intention or uptake for CC screening. We followed the PRISMA 2020 guideline and registered with PROSPERO (registration ID CRD42021276036). We searched the Web of Science, Scopus and EBSCO Medline Complete databases for eligible studies. Studies that conveyed informational material through e-health intervention were selected. The results were analyzed using narrative synthesis, and the pooled estimates were calculated using meta-analysis. A total of six studies involving 1886 women were included in this review. The use of e-health aids alone led to increased knowledge. The meta-analysis demonstrated that the mixed-education method of e-health movies and video education with didactic sessions increased CC screening uptake. A random-effects model revealed that CC screening uptake following e-health interventions were almost double of that of their comparison (odds ratio = 2.29, 95% confidence interval: 1.28–4.10, p < 0.05). Various areas of study demonstrated e-health intervention effectiveness (minority communities, urban areas, rural areas). Health education through e-health intervention has huge potential for promoting CC screening in the community. Nevertheless, the use of appropriate frameworks, user engagement and culturally tailored e-health need to be prioritized.

Published: August 2022

Economic growth becomes a critical component in the development of every country since it enhances living standards and other related concerns while eliminating poverty. As a developing country, Sri Lanka must place more emphasis to achieve sustainable economic growth. In addition, various factors have positive and negative impacts on economy’s growth. As such, the specific goals of any economy are to sustain long-term economic growth and low inflation. As a result, generally, high inflation is destructive for an economy and low inflation is beneficial. Therefore, it is worth investigating the impact of inflation on economic growth concerning a stable inflation level. This study examines the impact of inflation on economic growth in Sri Lanka by employing the Auto Regressive Distributed Lag model as the estimation technique. Furthermore, the findings illustrate a negative relationship between inflation and economic growth in the short run; when inflation increases by 1%, economic growth decreases by United States Dollar (USD) 3,427.94 million and long run economic growth declines by 107,263.8 million USD. Subsequently, with the current economic reality of Sri Lanka, the macroeconomic policies should be adaptable to maintain the stability of the inflation rate for a sustainable economy.

Published: August 2022

A part of students learning in the classroom depends on how the teacher responds to their thinking. The literature has separately addressed teachers’ feedback responses to errors and unexpected strategies that students put into play when solving tasks. We propose a framework to analyze these responses together based on three criteria: the focus of the answers (teacher or student), the type of knowledge (conceptual or procedural) that the teacher puts into play in the teacher-centered answers, and the types of actions (asking and proposing) involved in student-centered responses. We codified and analyzed the feedback responses of a group of mathematics teachers to a questionnaire that inquired about their curricular practices. We found similarities in their reports of responses to students’ errors and unexpected strategies: two-thirds of teachers have a teacher-centered response. For the student-centered answers, the number of responses of the teacher in which he/she proposes activities is three times the number of responses in which he/she asks students questions. Furthermore, responses to unexpected strategies differ from responses to errors because teachers evaluate, correct, and accept those strategies.

Published: August 2022

New effective biosorbents for the removal of Cu2+ ions from industrial wastewater were identified.
Premna serratifolia plant stem powder (PSSP) and its active carbon (PSSAC) were strongly observed
to adsorb Cu2+ ions in a wide pH range 6 to 9. Extraction conditions were optimized and sorption
capacities are found to be 40.1 mg/g for PSSP and 45.6 mg/g for PSSAC. The extraction of Cu2+ from
simulated solutions of concentration 25 mg/L were 85% with PSSP and 90% with PSSAC. Common
co-ions were marginally interfered. The spent sorbents can be regenerated and reused. Thermodynamic
studies revealed the spontaneity and favourability of the sorption process at high temperatures.
Homogeneity of sorbents surfaces and monolayer formation of Cu2+ ion on the surfaces, were inferred
from the analysis of adsorption isotherms. Pseudo-second order kinetics explain well the sorption.
The developed adsorbents were also effectively applied to treat polluted industrial effluents for the
removal of Cu2+ ions.

Lung cancer is expected to account for 11.4 % of the cancer burden in 2020, with an estimated 2.2
million new cases diagnosed and 1.8 million deaths occurring. Non-small-cell lung cancer accounted
for approximately 85% of newly diagnosed lung cancer cases. In non-small cell lung cancer and
tuberculosis level of vascular endothelial growth factor was found to be elevated, which induces
angiogenesis. In this study molecular docking analysis along with pharmacokinetic/ADMET and drug
likeness prediction were carried out to evaluate the newly designed indazole scaffolds as potent VEGFR
and Enoyl-ACP (CoA) reductase enzyme inhibitors. Out of 11 screened compounds, two compounds
having good scores (-7.72 and -7.54 kcal/mol) emerged as effective and potent VEGFR-2 inhibitors
and three compounds showed highest binding affinities (-8.30, -7.76, -7.62 kcal/mol) with
Enoyl-ACP. This study reveals that, newly designed indazole compounds could be the potential drug
of choice against non-small cell lung cancer and tuberculosis.

Published: August 2022

By free-radical copolymerization, a series of N-tert-butylacrylamide based hydrogels viz.
poly(N-tert-butylacryalmide-co-acrylamide/maleic acid) (HG11), poly(N-tert-butylacryalmide-coacrylamide/
N-isopropylacrylamide) (HG23) and poly(N-tert-butylacrylamide-co-acrylamide/acrylic
acid) (HG35) were synthesized. Infrared spectral investigations, SEM, XRD, and TGA were used to
characterize the prepared hydrogels. Biofilm quantification for Staphylococcus aureus and Pseudomonas
aeruginosa was assessed in vitro using the microtiter plate (MTP) approach. The hydrogels were
found to have the least amount of biofilm formation on their surfaces, indicating that they have superior
antibiofilm action and thus low fouling. Fluorescence microscopy was used to examine the morphology
to supplement the biofilm inhibition. Among the three hydrogels, HG11 and HG35 were found to be
more effective against S. aureus than P. aeruginosa. But HG23 caused more fouling resistant for P.
aeruginosa than S. aureus.

Comparative Study of Production of Biodiesel Utilizing Calcinated Eggshell and
Immobilized Lipase-Eggshell Catalysts by Waste Cooking Oil, Catalysts
Characterization and Yield Optimization
Authors: Kumar Harendra , Renita A. Annam
Published: August 2022

Due to the high demand, cost and environmental toxicity of fossil fuels, mainly petroleum and diesel,
there is a massive demand for alternative fuels based on biological origin. The production of biodiesel
from cheap resources has gained more attention. Present study conducted biodiesel production from
waste cooking oil utilizing calcinated eggshells and immobilized lipase. The eggshell was calcinated
at temperature ranges from 500-800 ºC and characterized by TGA, SEM, XRD and FTIR analysis; the
study of characteristics of calcinated eggshell was helpful in the production of biodiesel, it is around
~42% yield production achieved at 60 ºC, 1000 rpm revolution of stirrer for O/A (oil/alcohol) molar
ratio 1:6. Now the lipase of activities 40 μ/g immobilized with eggshell, the eggshell-lipase catalyst
(ELC) gives the yield of ~92% at 40 °C, 500 rpm revolution of stirrer and O/A molar ratio 1:6 after
transesterification process on waste cooking oil (WCO) with calcined eggshell and reusability
application of ELC. The production of biodiesel by immobilized catalyst at a higher temperature will
reduce the thermal stability of lipase. To get the maximum biodiesel yield, the transesterification
process must undergo at an optimum higher temperature. This is overcome by immobilizing the
commercial lipase with an eggshell that can withstand even higher temperatures (40-45 ºC) without
losing its activities. The processes and optimization are globally integrated to improve the feasible
evaluation of economic improvement for biodiesel production.

A dihydroperchlorate salt of octamethyl derivative of 14-membered tetraazamacrocycle,
Me8[14]diene·2HClO4 (L·2HClO4), was formed by the condensation of 1,2-diamino propane with
acetone in the presence of a quantitative amount of perchloric acid, which on extraction with chloroform
at pH above 12 yielded free ligand (L). The interaction of rhodium(III) trichloride trihydrate and
platinum(II) chloride with free ligand L produced six-coordinated octahedral orange-red complex,
cis-[RhLCl2]Cl and four-coordinated square-planar yellow complex, [PtL]Cl2, respectively. Axial
substitution reactions on [RhLCl2]Cl with KX (X = NO3, Br or I) and NaNO2 afforded six-coordinated
deep brown products [RhLY2]Y (Y= NO3, Br, I or NO2). The ligand and metal complexes were
characterized based on analytical, molar conductivity, spectroscopic and magnetochemical data. The
antimicrobial activities of the concerned ligand and its complexes have been explored against some
selected bacteria and fungi.

PT X is an information and communication company as well as a complete telecommunication service and network provider in Indonesia. In serving customer needs related to services, PT X has Plasa spread across 535 outlets throughout Indonesia until 2019.. Plasa is PT X outlet or place of service, which is fully managed by PT X or in cooperation with service partners. According to the explanation given by the Team Leader Plasa has service standards in serving customer needs including the standard customer service time is 10 minutes and the standard number of customers per CSR is 15 customers. But at PT X Yogyakarta the system actually only has one Customer Service to serve 50 customers and the service time sometimes exceeds the predetermined time standard. This resulted in quite long queues and long waiting times. The purpose of this research is to know the appropriate queue simulation model using flexim 6.0 so that waiting time at Plasa can be minimized. The average waiting time required by customers in the queuing system at Plasa is 3248.44 seconds and based on the alternatives that have been made, it can be seen that experiment 1 is the best, this is because the maximum waiting time achieved is better than experiments 2 and 3.
Online versus online plus face-to-face class: The case of International Economics and International Finance
Authors: Kurihara Yutaka
Published: August 2022

COVID-19 has not ended yet and most colleges and universities all over the world could not yet resume face-to-face classes, instead having had to conducted online classes. This situation was common in 2020, however, the situation has gradually changed since 2021. From the changing of delta strains to omicron strains of COVID-19, there were some periods that the number of critically ill patients had decreased rapidly. Most colleges and universities in Japan have transitioned back to face-to-face classes during the semester from online classes. This study examines how the outcome of online class versus online plus face-to-face class changed empirically. The empirical results using difference-in-difference show that introducing face-to-face classes increased the outcome of learners’ performances. While online classes do have some merits, reintroducing face-to-face classes increases learner outcome to a greater extent. Flipped classrooms could give us some good roads to promote the class outcomes.
Shi Zhengyi on China Ethnic Minority Areas Economic System Reform
Authors: Guang Xia Dongming Tian
Published: August 2022

This article introduces Professor Shi Zhengyi’s early theoretical thinking on reforming the Chinese ethnic minority economic system. Due to historical and political reasons, China’s new economic system China built a planned economic system after the founding of the People’s Republic of China. This economic system helped China develop its industries. But this rigid economic system became incompatible with product development, especially in ethnic minority areas. Ethnic minority areas were backward in production and unbalanced in development. After 1978, China gradually built its new socialist economic system, a planned commodity economy based on public ownership. In this economic system reform, the minority autonomous areas should be open to foreign countries, introduce advanced technology and investment, and develop import and export trade. At the same time, the minority autonomous areas should strengthen economic cooperation with other regions. Ethnic minority areas must also carry out comprehensive economic system reform, which should fully consider the specific characteristics of these areas, especially the ethnic and regional factors.
How and What has Influenced Cryptocurrency Prices? Economic influences or political Influences
Authors: Kurihara Yutaka
Published: August 2022

Cryptocurrency has been prevailing gradually with repeating fluctuation in value. Cryptocurrency is not classified as a legal currency but a private financial management system that self-managed and is not managed by central banks or governments. Cryptocurrency is different from any other currency used around the world. Unlike central bank- and government-issued currency, the value of cryptocurrency is able to be inflated as the volume of it has a finite limit. The usage of cryptocurrency enables us to send or receive any amount of currency to anyone at a very cheap cost compared to other monetary instruments. Since the introduction of cryptocurrency, it has received much attention. The trading volume of cryptocurrency has been increasing rapidly although the value has crashed occasionally. Some serious incidents have occurred, however, cryptocurrency may have overcome these situations. How and what has influenced cryptocurrency value has been discussed a lot from the view of economic aspects, however, a common consensus has not yet been reached. For this issue, there is a large difference from stocks or other financial assets or financial instruments. However, there is some possibility that political influences rather than economic influences may have impacts on the prices of cryptocurrency. This study employs U.S.-China trade disputes and examines the effects on prices of cryptocurrency. The results show that political issues along with economic issues, including some asset prices, have some influence on cryptocurrency.
A Critical Analysis of the Compulsory Science Education Policy at the Secondary Level of Education in Uganda
Authors: Milliam Kiconco , Dominic Karyarugokwo
Published: August 2022

Uganda is one of the African countries that have been focusing on the science-led strategy to promote growth and development. One of the strategies is the science promotion policy, which started in 2005 and among other things made learning and enrolling on science subjects (mathematics, chemistry, physics and biology) compulsory at the ordinary level of secondary school education. This paper has, therefore, used a secondary review methodology to critically analyse the science policy at the secondary school levels (ordinary and advanced). The paper begins with an introduction that discusses the history of curriculum reform at the secondary school level globally and in Africa with emphasis on Uganda. It also discusses Uganda’s science policy implementation strategies, which included the government's effort in providing resources such as laboratory equipment and science textbooks to government-aided schools. There is, then, a section that discusses the challenges that have hindered the successful implementation of science policy. This section shows that much as the government of Uganda has tried to facilitate science policy, the latest being the enhancement of salary for scientists, including science teachers by 300%, factors such as unresponsive curriculum content, shortage of qualified science teachers and inadequate laboratory equipment remain challenges to the, otherwise, good policy. The paper concludes by stating that improvement in science performance requires a multi-dimensional approach and, therefore, the recent salary enhancement that only catered for science teachers may not, necessarily, achieve much as far as improvement in the performance of students in science subjects is concerned

Tell me a curious (hi)story. Historical content in Vitruvius’ De architectura
Authors: Kołoczek Bartosz Jan
Published: August 2022

The article examines the significance of history–themed passages (historiae) in Vitruvius’ architectural treatise De architectura and assesses their veracity vis–à–vis their rhetorical impact. The article’s particular focus lies on Vitruvius’ reflections on history, since the sound knowledge of it—as the author claims—is vital for any competent architect. It asserts that Vitruvius tends to stretch the historical truth whenever he makes an attempt at self–promotion (as an author or an architect) or seeks to win the approval of his patron emperor Augustus, to whom he dedicated his work.

Acoustic space in narration from the perspective of production
Authors: Fu Xiuyan , Cai Fang
Published: August 2022

A major mark of the progress of human society is its transition from the production of things in space to the production of space itself. Oral narrative covers a certain range of space with sound, and physical spaces such as theaters, cinemas, and concert halls accommodate various forms of narrative communication. Drama was the most popular form of mass communication in the pre-industrial age, and its performance required a “sound wall” around the theater to keep people focused. Comment and discussion were both significant forms of narrative consumption. Some consumers who paid more attention to “being seen” even regarded the communication arena as a social platform. In present times, commentary subtitles (Danmaku in Japanese) pop up on computer screens from time to time to make consumers feel as if they are chatting with people while watching. “Chatting” in social media groups also belongs to interaction in virtual space. Surround sound in the cinema wraps the audience and screen into a unifying auditory space, blurring or even eliminating the boundaries between them. Narrative has been an act of producing acoustic space from the very beginning. Nowadays, people adopt more abundant narrative means yet still rely on the imitation of auditory communication.
Global stability for a SEIQR worm propagation model in mobile internet
Authors: Zhang Liang , Liu Pengyan
Published: August 2022

Recently, propagation models of worms in the mobile environment are drawing extensive attention, particularly in the Wi-Fi scenario. Considering that worm-free equilibrium is exponential convergent means that the propagation time and control time of worms are much shorter than for other asymptotic convergence. Besides, the global asymptotic stability of the endemic equilibrium is more important than the local asymptotic stability, which reflects the more global qualitative behavior of the worm propagation. In this paper, we discuss the global dynamics of SEIQR worm propagation model in mobile internet proposed by Xiao et al. [X. Xiao, P. Fu, C. Dou, Q. Li, G. Hu, and S. Xia, “Design and analysis of SEIQR worm propagation model in mobile internet,” Commun. Nonlinear Sci. Numer. Simulat., vol. 43, pp. 341–350, 2017] to improve and complement the related results. Through a series of mathematical derivations, sufficient conditions are derived to ensure the global exponentially stability of worm-free equilibrium, and the exponential convergent rate can be unveiled. Then, by using the classical geometric approach, it is shown that the endemic equilibrium is globally asymptotically stable and the system is persistent when R
0 > 1. Moreover, numerical simulations are given to demonstrate our theoretical results.

mm2 remain out of reach even in the visible frequencies. In this work, a novel hot-electron-based, non-trench-type photodetector exploiting pure photoexcitation in a thin aluminum (Al) film and leaky plasmonic modes at and between its heterojunctions is proposed, analyzed, and experimentally demonstrated. Combining diffracted-order-resolved analytical analysis and numerical computations unravels the optical absorption mechanism of the innovative design. Leaky surface plasmon resonance (with leakage radiation into the air) produced by a propagating diffracted order and quasibound supermodes (with power leakage via coupled gap plasmon polariton and bound surface plasmon polariton modes) excited by evanescent diffracted orders are shown to significantly contribute to the absorptance in the preferred thin Al film where hot electrons are generated. At 638.9 nm and electric bias −0.9951 V, the measured per-unit-area responsivity, detectivity, and the external quantum efficiency reach 298.1444 μA/mW/mm2, 4.3809 × 109 cm Hz1/2/W, and 2.6878%, respectively, from an active area of 4.6457 × 10−2 mm2. The performance is among the best of those previously reported operating at similar wavelengths and biases. The RC time constant is estimated to be about 1.673 μs from the current-voltage measurements. The physical insight into the innovative, experimentally demonstrated device could lay the groundwork for the practical use of low-voltage, metal-based photodetection.
Study of baryogenesis in the framework of Hořava–Lifshitz cosmology with Starobinsky potential
Authors: Chakraborty Gargee , Chattopadhyay Surajit
Published: August 2022

Motivated by the work of Paliathanasis et al. (A. Paliathanasis and G. Leon, “Cosmological solutions in Hořava–Lifshitz scalar field theory,” ZnA, vol. 75, p. 523, 2020), this work reports the baryogenesis in Hořava–Lifshitz cosmology by taking the background evolution as modified Chaplygin gas and modified holographic dark energy. The Starobinsky potential has been selected to initiate the study. The scalar field and its potential have been reconstructed and found to be consistent with the universe’s expansion. The quintessence behaviour of equation of state parameters has been observed for both cases. Finally, baryogenesis has been studied in both cases. The baryon entropy ratio attained the observed value. It is also well explained that either the model will achieve an equal number of baryon and antibaryon densities or will satisfy the Generalized Second Law of Thermodynamics.

Published: August 2022

A scoping review methodology was used to assess player readiness via indicators of neuromuscular function in response to training load. Literature search included PubMed, Web of Science, SportDiscus, and CINAHL. Search strategy was based on Population-Concept-Context framework evaluating football code athletes with the focus on player readiness in the context of longitudinal monitoring across quantified training loads with an emphasis on neuromuscular function. Demographics, frequency of data collection, methods of monitoring readiness, neuromuscular function, duration of monitoring period, and quantification of training loads were reported. Authors independently reviewed articles and, in the case of disagreement, a vote determined inclusion. The sports of rugby (n = 13) and soccer (n = 11) were most frequently examined, followed by Australian Rules Football (n = 6) and American Football (n = 1). The most common methods assessed systemic readiness with the primary focus on jump and sprint testing. Findings identified limited evidence supporting structural and tissue-specific monitoring tools. Player readiness assessment strategies have evolved with advances in technology and analytics. It is recommended that future research focus on a variety of populations, including youth and women athletes. This review is the first to summarize methods of assessing player readiness using indicators of neuromuscular function in football code athletes.

Indonesia does not allow the use of narcotics except for medical purposes. Drug use for medical purposes must be under supervision of doctor, regardless of the level of content in it. In contrast to Netherlands, which allows the use of Soft Drugs as regulated in Dutch Opium Act. In Netherlands itself, the use of marijuana and the purchase of marijuana can be done at a coffee shop that already has a permit. The legalization of certain types of drugs and for certain purposes exists because Netherlands wants to provide legal certainty for their people. Netherlands want drug trafficking not to be carried out by crime syndicates that will harm their people. In addition, Netherlands also provides adequate health facilities for drug addicts. Evidently, number of addicts, number of HIV infections due to injection needles, and deaths from drugs has decreased. This is what distinguishes drug policy in Indonesia and Netherlands. Indonesia prioritizes the Penal Policy, it can be seen from the punishment of drug users. While Netherlands prioritizes Non-penal Policy, it can be seen from the incessant drug control. What can Indonesia follow from the drug policy in Netherlands is the prevention of drugs with state control over drug trafficking accompanied by adequate health facilities. Indonesia should reduce the punishment of drug addicts. Criminalizing drug addicts will not solve the problems. In the case of drug abuse, addicts are also victims.
EXTENSIVE EXPERTISE IN ENDOCRINOLOGY: Osteoporosis management
Authors: Reid Ian R
Published: August 2022

Fractures occur in about half of older White women, and almost a third of older White men. However, 80% of the older individuals who have fractures do not meet the bone density definition of osteoporosis, suggesting that this definition is not an appropriate threshold for offering treatment. Fracture risk can be estimated based on clinical risk factors with or without bone density. A combination of calculated risk, fracture history, and bone density is used in treatment decisions. Medications available for reducing fracture risk act either to inhibit bone resorption or to promote bone formation. Romosozumab is unique in that it has both activities. Bisphosphonates are the most widely used interventions because of their efficacy, safety, and low cost. Continuous use of oral bisphosphonates for >5 years increases the risk of atypical femoral fractures, so is usually punctuated with drug holidays of 6–24 months. Denosumab is a further potent anti-resorptive agent given as 6-monthly s.c. injections. It is comparable to the bisphosphonates in efficacy and safety but has a rapid offset of effect after discontinuation so must be followed by an alternative drug, usually a bisphosphonate. Teriparatide stimulates both bone formation and resorption, substantially increases spine density, and reduces vertebral and non-vertebral fracture rates, though data for hip fractures are scant. Treatment is usually limited to 18–24 months, followed by the transition to an anti-resorptive. Romosozumab is given as monthly s.c. injections for 1 year, followed by an anti-resorptive. This sequence prevents more fractures than anti-resorptive therapy alone. Because of cost, anabolic drugs are usually reserved for those at very high fracture risk. 25-hydroxyvitamin D levels should be maintained above 30 nmol/L, using supplements if sunlight exposure is limited. Calcium intake has little effect on bone density and fracture risk but should be maintained above 500 mg/day using dietary sources.

Published: August 2022

In order to evaluate the effect of copper sulfate pentahydrate CuSO4.5H2O in the control of coffee rust Hemileia vastatrix Berk. et Br. the present research was carried out in the Toquián neighborhood of the San José Ixtepec ejido, municipality of Motozintla, Chiapas, Mexico. The experimental unit corresponded to 16 coffee trees and the useful plot with four central coffee trees, with five treatments: 0.5 l ha-1, 1.00 l ha-1, 1.50 l ha-1, 2.00 l ha-1 of copper sulfate pentahydrate and a control without application. A randomized block design with five treatments and four replicates was used, which resulted in 20 experimental units. The percentage of infection of coffee rust was evaluated before the application of copper sulfate pentahydrate, 15, 30, 45 and 60 days after application. Data in percent were transformed to sine arc √percent. The results show that the highest percentage of coffee rust infection was observed in the control treatment without application with an average of 22.12%, and the lowest infection in the highest dose treatment 2.00 l ha-1 with 7.33%. The results will be fundamental to put them into practice and thus develop strategies to control and combat coffee rust that will allow better production in the coffee plantations of the study area and the region.
Physical Model of Influence of CaO–FeO–SiO2 Powder Fraction on the Heat Transfer from Torch
Authors: Molchanov L. , Golub T. , Synehin Ye. , Semykin S.
Published: August 2022

Introduction. One of the main ways of heat transfer in metallurgical units is the interaction of the charge with a burning gas torch. The heat is transferred from the torch mainly by radiation. In particular, oxygen converter process under its typical temperature and chemical conditions of oxidation processes is accompanied by combustion reactions with the formation of a torch both in the cavity of the converter (in the so called reaction zone) and above the converter neck as a result of partial post-combustion of exhaust gases leaving the unit.Problem Statement. The processes in metallurgical units are accompanied by significant smoke and dust, which affect the efficiency of heat transfer from the torch of exhaust gases post-combustion to the metal bath that is an additional source of heat in the converter process.Purpose. The purpose of this research is to study the influence of the introduction of solid powder components into the environment around the torch on its heat transfer.Materials and Methods. The research has been carried out on the physical model of a burning torch when CaO-FeO-SiO2 system powders are fed into the torch in air flow. The magnitude of the heat flow density has been estimated on the basis of the registered temperature difference in different parts of the model.Results. It has been established that the feed of air or any solid material at a temperature much lower than the torch temperature has a negative effect on heat transfer from the torch by radiation. However, the total heat flow density is not significantly reduced due to the possible involvement of heated solids in other heat transfer methods. For the CaO-FeO-SiO2 system, the share of silicon dioxide powder as a component with the highest heat capacity has the greatest negative effect on the heat transfer from the torch.Conclusions. The studies based on the physical model have allowed us to qualitatively assess the effect of dustiness of the components of CaO-FeO-SiO2 system of the burning torch environment on its heat transfer and on the contribution of different heat transfer methods from the torch to the total heat flow density in given conditions.

Introduction. Innovative approaches in the field of digitalization of the judiciary of Ukraine include the development of network technologies, introduction and improvement of electronic court document management, creation of automated systems for generalization of judicial practice and analysis of court activity, updating the telecommunications structure of courts, creating a single judicial database.Problem Statement. An important research task is the monitoring of “electronic tools” for modelling litigation in order to complete, timely, impartial, expedited and effective consideration of court cases, as well as the development on this basis of legislative and law enforcement proposals.Purpose. Theoretical understanding of the role of law and law enforcement practice in the process of using e-democracy tools in the judiciary.Materials and Мethods. Logical law, comparative law, empirical, deductive and systematic methods of analy sis of the development of electronic litigation in Ukraine.Results. The current state of implementation of the Unified Judicial Information and Telecommunication System in Ukraine has been analyzed. Legal monitoring of the legislative framework for e-court regulation in Ukraine has been conducted.Conclusions. In order to improve the legal basis for modelling litigations in Ukraine, the following issues need to be addressed: 1) access to court by videoconference for the parties to the case; 2) use of all possible (existing) messengers for communication with the court; 3) appeal to the court (submission of documents) exclusively in electronic form; 4) remote form for jurisdictional proceedings; 5) remote access to court records for all employees; 6) the possibility of signing the text of the decision without a personal presence in court (electronic signature); 7) automatic distribution of cases between all judges of Ukraine of the relevant specialization (departure from territorial jurisdiction).

O presente texto se caracteriza como um exercício interdisciplinar entre a História da Arte e a arqueologia, na observação da arte rupestre. Para isso, levantamos bibliografias clássicas da história da arte que abordam a arte rupestre e depuramos as linhas mestras de como o tema é tratado, estabelecendo críticas à produção analisada. No segundo momento, buscamos as orientações teóricas e metodológicas da história da arte que pudessem ser aliadas às perspectivas arqueológicas e contribuíssem para a compreensão dos caminhos análogos e das diferenças na abordagem da arte rupestre. Em função das evidências de uma herança epistemológica comum entre a história da arte e a arqueologia, entendemos que é alto o potencial para uma reaproximação entre esses campos de conhecimento, a qual poderá ser materializada, sobretudo com a adesão de historiadores da arte ao trabalho com a arte rupestre associada a contextos sociais ativos.
