"This article examines the phenomenon of interculturality through the lens of the Liang Zhu Concerto for Violin and Orchestra by He Zhanhao and Chen Gang. Interculturality is no longer merely a means of elevating the axiological value of a given context but has become a necessity for authenticating contemporary discourse. The role of interculturality in shaping the expression of creative intentions is amplified, as it attenuates divergences determined by the incongruity of individuals’ backgrounds by comprehensively observing the uniqueness of foreign elements from a familiarity-based perspective. The Liang Zhu Violin Concerto exemplifies the adaptation of East Asian culture to the context of the Western language and means of expression while preserving its Chinese cultural identity. This concerto has significant value and desirability for consumption due to the proportion of originality and familiarity which it upholds and determines its overall appeal. Ultimately, this article aims to explore how the Liang Zhu Violin Concerto achieves originality at a global level while preserving its Chinese cultural identity. Keywords: Interculturality, Liang Zhu, Identity, Imitation."
Sopranotronics 101. An Analytical Approach With Repertorial Proposal

Published: August 2023

"The current work aims to present an investigation of the past seventy years of Sopranotronics repertoire, approached through the eye of the performer. The Soprano Fach and the electronic environment merged in the last decades into a new interdisciplinary performance field, which is both artistic and scientific in its making. The Sopranotronics now offers a fresh vocal repertoire with challenging drama stories and thought-provoking art. Whether expressing a political disagreement (Nono’s La Fabbrica Illuminata) or describing a mythical story (Babbitt’s Philomel) in chamber works; writing a four-hour opera without dramatic action and a storyline (Glass’s Einstein on the Beach) or inventing the disembodied performance while the most humane character of the opera suffers because of this (Machover’s DATP) or chanting for spirits in an electro - acoustic aria (Crețu’s I.X.@100) and challenging any musical and vocal establishment in a dadaistic formula (Beldean’s Tekmirio) brings forward the human component of this experimental art worth performing. Keywords: Sopranotronics, Soprano Fach, electronic music"

Published: August 2023

Background: Cyberbullying is a serious problem experienced by almost all countries. In Indonesia, the highest internet users are adolescents, so that adolescents are at risk of experiencing cyberbullying. Cyberbullying is bullying that is done through social media. Bullying carried out both traditionally and through social media has a psychological impact in the form of feelings of sadness and suicide attempts.
Purpose: to determine the relationship between cyberbullying and the risk of suicidal ideation in adolescents.
Methods: this study was a correlational study with a cross-sectional approach of 1.043 students from ten state high schools and four state vocational schools with random sampling. Data analysis used the Chi-Square test, Kruskal-Wallis test, and Mann-Whitney test.
Results: As many as 21.0% of adolescents involved in cyberbullying are at risk of suicidal ideation. There is a relationship between cyberbullying and the risk of suicidal ideation in adolescents p = 0.000 (p <0.05).
Conclusions: The risk of suicidal ideation is not only for adolescents who are involved as victims of cyberbullying but also affects adolescents who are involved as perpetrators, both perpetrators and victims.
Las emociones en el tribunal: Teoría e instrucciones de uso (Aristóteles, Retórica III)
Authors: Viano Cristina
Published: August 2023

El largo y conocido análisis de las pasiones como instrumentos de persuasión en el Libro II de la Retórica se considera la fuente principal para reconstruir el complejo rompecabezas que es la teoría aristotélica de las emociones. Pero es en el Libro III, dedicado a la expresión lingüística del discurso (léxis) y al orden de sus partes (táxis), donde Aristóteles nos brinda de forma concreta las instrucciones para el uso de las emociones y los mecanismos psicológicos que atañen a la persuasión, como la mímesis y la empatía. El análisis diversificado del factor emocional en las distintas partes del discurso no solo complementa la "retórica de las pasiones" del Libro II, sino que permite también comprender mejor la estructura de la propia Retórica y demuestra que el tema de las pasiones puede considerarse uno de los hilos conductores de todo el tratado.
Clinical risk and patient safety: a multicenter cross-sectional study to explore knowledge, attitudes and practice of hospital nurses
Authors: Guillari Assunta , Petitti Tommasangelo , Esposito Maria Rosaria , Rea Teresa
Published: August 2023

Objectives: To investigate knowledge, attitudes, and behavior of nurses working in acute care hospitals regarding clinical risk and patient safety, and to identify predisposing factors.

Design: Cross-sectional multicenter study.

Methods: The study was conducted in thirteen non-teaching acute public and private hospitals of a region of southern Italy from September through December 2015. A structured self-report questionnaire was administered to clinical nurses working in the hospitals involved. Three multivariate linear and logistic regression models have been constructed: knowledge of the definition of an adverse event; attitude towards risk of making an error while working and nurses who reported at least one error in the past 12 months.

Results: The sample consisted of 484 respondents out of 670 (72.2%) nurses approached. The final multivariable model showed that educational courses about patient safety play a significant role in nurses gaining knowledge of adverse events. In the absence of organization-wide patient safety programs, nurses with low knowledge levels showed a significantly higher perceived risk. Nurses (n=96) who made errors over the past 12 months had discussed them with head nurses (75%) and colleagues (41.7%). Anonymous reporting to the organization was very low, with only 8.3% of nurses who had made an error submitting an anonymous report.

Conclusions: Managers should implement multimodal improvement strategies aimed at enabling nurses’ to recognize the critical issues of the system and to increase their reporting, in order to make the organizations safer.

The COVID-19 pandemic has an impact on both the food sector and people’s eating habits. This study aims to understand the impact of COVID-19 on the economic and financial outcomes of the canned foods, sauces, and condiments sector of several companies. Three KPIs, current ratio (CR), EBITDA, and total debt, of Kraft Heinz Company Brazil (KHC Brazil) over the years 2018 to 2023 are analyzed by referring to its financial statements. Finally, the three KPIs are analyzed together, and visions for three different scenarios at different times are extracted.
Qualitative and Quantitative Analyses of the Enantiomers of Nicotine and Related Alkaloids Employing Chiral Supercritical Fluid Chromatography in Commercial Nicotine Samples and in E-Cigarette Products
Authors: Perfetti T.A. , Ashraf-Khorassani M. , Coleman W.M. , Dube M.F.
Published: August 2023

Several commercial sources of tobacco-derived nicotine (TDN) and synthetic nicotine (SyN) and a variety of e-cigarette liquids employing either TDN or SyN have been evaluated to determine the enantiomer distributions of R- and S-nicotine and R- and S-nornicotine by chiral supercritical fluid chromatography (chiral-SFC) with UV diode array detection (DAD-UV). The data generated are used to test the mismatched vs. matched hypothesis of Cheetham
et al. as a means to distinguish products containing TDN from products with SyN.

Two sets of experiments were conducted in this study. The first experiment was conducted on a series of 11 commercial nicotine samples (three characterized as tobacco-derived and eight characterized as synthetic nicotine). The commercial nicotine samples were either from a tobacco-derived nicotine (TDN) source or were synthetic nicotine (SyN). Some of the commercial nicotine samples were nicotine salts. The second experiment was conducted on e-liquids from a set of 11 e-cigarettes. The nicotine in the e-liquids was either from TDN or SyN. The e-liquid samples were differentiated based on the advertised information on the internet or from printed information on the e-cigarette packaging.

None of the three commercial TDN samples in the first experiment could be unequivocally characterized as coming from a tobacco source. Five of the eight commercial SyN samples were correctly characterized as SyN based on the matched vs. mismatched nicotine and nornicotine hypothesis of Cheetham
et al.

In the second experiment, none of the e-liquids characterized as being from TDN sources could be unequivocally characterized as coming from a tobacco source. All of the e-liquids characterized as being from SyN sources were either characterized as equivocal or of uncertain origin based on the matched vs. mismatched nicotine and nornicotine hypothesis of Cheetham
et al.

These sets of experiments represent an excellent example of the difficulty that the United States Food and Drug Administration is having in trying to determine if TDN or SyN is being used in tobacco products. Even highly advanced chromatographic methods such as chiral-SFC were not able to unequivocally distinguish products with TDN from products with SyN 100% of the time.

Other analytical methods such as 14C quantitation of nicotine samples by accelerator mass spectrometry offer a more reliable determinate of nicotine source (TDN vs. SyN) and can be used to identify misbranded products labelled as containing SyN, even though this methodology is more expensive and offered in limited locations.
Motivations and Self-Perceived Career Prospects of Undergraduate Sociology Students
Authors: Sándor Alexandra Valéria
Published: August 2023

Sociology undoubtedly plays an important role in the world of sciences, as it provides an opportunity to examine the society in which we live and our social relationships using widely accepted means with real scientific value. As Giddings has noted, ‘sociology tells us how to become what we want to be’ (Giddings, 2011). However, discussions of the social sciences can be controversial, as they are sometimes perceived as ‘inferior’ to natural sciences. To alleviate this discrepancy, it is essential to supply professionals with useful knowledge in the field of sociology, understand their motivations and ensure the best career prospects for them. In this pilot study, 18 sociology B.A. students answered seven open-ended questions in the form of a short essay regarding their motivations in terms of faculty choices, initial expectations and the fulfilment thereof, their aims in the study of sociology, preferred areas of employment, willingness to undergo further training, five-year plans and their opinions about the prospects of newly graduated sociologists in Hungary compared to graduates from other areas in terms of the usefulness of knowledge gained, perceptions of their professions and earning opportunities. According to the results of this study, the future plans of the participants were very different, but all of them believe that an undergraduate sociology degree provides extensive knowledge about the functioning of society and has helped them to form attitudes that they consider to be extremely valuable on the labour market.

Published: August 2023

Learning Management Systems (LMS) or Learning Content Management Systems (LCMS) are the core of e-learning platforms and have evolved according to the development of new information and communication technologies. In this type of software there are many products on the market, some developed by the institutions themselves (in-house), others are free and open source software (FOSS) and others are more commercial, varying in functionality and technology, but almost always adhering to the standards used in e-learning so that learning objects fulfill their purpose of being usable and reusable. This paper introduces you to current LMS / LCMS, main functions, distinctive features, related standards, and their current status. Then there is a presentation of Machine Learning as a branch of Artificial Intelligence and Cognitive Computing as a fusion discipline between computation, cognition, psychology and artificial intelligence, to end in a proposal for the incorporation of these technologies in a new generation of e-learning platforms, all in an integrated framework of interoperability and governance.
Computer Simulations of Ethics: The Applicability of Agent-Based Modeling for Ethical Theories
Authors: Lasquety-Reyes Jeremiah A.
Published: August 2023

I consider the applicability of Agent-Based Modeling (ABM) and computer simulations for ethical theories. Though agent-based modeling is already well established in the social sciences, it has not yet found acceptance in the field of philosophical ethics. Currently, there are only a few works explicitly connecting ethics with agent-based modeling. In this paper, I show that it is possible to build computer simulations of ethical theories and that there are also potential benefits in doing so: (1) the opportunity for virtual ethical experiments that are impossible to do in real life, and (2) an increased understanding and appreciation of an ethical theory either through the programming implementation or through the visual simulation. In the first part of the paper, I mention some social science simulations with ethical import that could encourage ethicists to work with ABM. Second, I list the few pioneering works that attempt to combine computer simulation with philosophical ethics, the most prominent being Evolving Ethics: The New Science of Good and Evil (2010) by Mascaro et al. Third, I give pointers for the computer simulation of the most prominent ethical theories: deontological ethics, utilitarianism, feminist care ethics, and virtue ethics. In the final part, I consider the potential of using an existing reference model for the simulation of human behavior, the PECS model, as the foundation for a computer simulation of virtue ethics.

The Public Expenditures and Economic Growth: DSGE model for Bosnia and Herzegovina
Authors: Bošnjak Nikolina
Published: August 2023

The DSGE (Dynamic Stochastic General Equilibrium) methodology attempts to explain the behavior of aggregate economic phenomena, such as economic growth, business cycle, and the effects of monetary and fiscal policy, using macroeconomic models derived from microeconomic foundations. DSGE models study the economy evolution (dynamics) over time. They take into consideration the fact that economy may be affected with random (stochastic) shocks. Still, they include all markets in the economy and assume that those markets balance out rapidly (general equilibrium). DSGE models have become the main tool of macroeconomic analysis, and until now, a huge number of different DSGE models have been developed. They are used for forecasting, different economic policies analysis and giving policy advices. Due to data scarcity and lack of knowledge, indevelopment and many other reasnos, until now there was no application of DSGE models to Bosnia and Herzegovina case. That is why we were motivated to calibrate a small size DSGE model for Bosnia and Herzegovina. In this research we will calibrate a small open economy DSGE model for Bosnia and Herzegovina and use its results to give some advices for economic growth of Bosnia and Herzegovina improvement. The special attention will be given to Public expenditures and TFP influence on Bosnian macroeconomic variables.
SMEs and Family Smes: Specificities from the Portuguese Socio-Business Context
Authors: Marques Ana Paula , Couto Ana Isabel
Published: August 2023

The composition of the corporate structure constitutes a relevant indicator of the entrepreneurial and economic dynamism of a certain country or territory. In contrast to past estimates over the past 45 years, the importance of small or very small scale entreprises has been steadily decreasing in the Portuguese business universe. The Portuguese socio-entrepreneurial fabric is predominantly constituted by small and very small scale businesses (micro companies): in 2015, 99,9% of the non financial Portuguese sector were SME [Small and Medium-size companies], and the micro scale companies represented around 96% of the total number of SME. In this context, family businesses acquire greater relevance due to/for the estimated weight they have on the economy (between 70% to 80% of the SME, also including great companies quoted on the stock exchange markets), on the creation of jopbs and on the role they play in the local development. Notwithstanding, there still is a significant unawareness of the business layouts of the family companies. In effect, these tend to be heterogeneousin terms of size, activity sector and degree of professionalization of the respective government models and human resources..The ongoing project, “Roadmap for the Portuguese family businesses” (2016-2018), financed by the NORTE 2020/ FEDER has as a central goal to contribute to a better acknowledgement and assessment of the impact of family companies in the northern region, as far as the local, national and international economy is concerned. For this purpose, it will build a database of the Portuguese northern region, mapping all the companies that present the layout of a family business and apply an online survey, combined with in-depth interviews to the various types and segments of family businesses, reinforcing their economic and social roles.

Published: August 2023

The study presents a new approach to understand the mind of the persons in order to drive desired action in crisis situation, specifically the COVID-19 pandemic. Understand the mind of the shopper in a pandemic situation, with massive uncertainty, should provide direction for governments and the retail trade to adopt practices and communications which will reassure their customers. This study investigates the nature of what people will do to reassure themselves in the pandemic, and has been executed during the period of the pandemic, making the study relevant to the actual events taking place. The focus of the study is on the likelihood of buying ordinary food, given certain descriptions. The study revealed three mind-sets, clusters of individuals who respond to the pandemic in one of three ways. These are: Mind-Set 1: Focus on sanitation & supply; Mind-Set 2: Focus on budget for lifestyle; Mind-Set 3: Focus on shopping, personal needs, consumption. These mind-sets are distributed through the population, and are not limited to specific age or gender. The paper closes with the PVI, personal viewpoint identifier, to assign a new person to one of the three mind-sets.

Published: August 2023

One of the many challenges in running a business is cost accounting. While there are many different costing methods, there is still a need to create new ones. The aim of this article is to develop a new method of cost calculation, which is adapted to modern conditions related to the adaptation of products to the needs of customers. This article presents an original method of determining production costs, which is based on the labor consumption of products. This method is a combination and development of known methods; however, by applying more precise accounting bases, it leads to more precise results. The developed method of cost calculation, thanks to its universality, can be used in most enterprises.
Post-Operative Delirium Masking Acute Angle Closure Glaucoma
Authors: Sim Zariel Jiaying , Jieyin Xing , Suhitharan Thangavelautham
Published: August 2023

Introduction

Acute angle closure glaucoma (AACG) is an ophthalmological emergency, and can lead to the devastating consequence of permanent vision loss if not detected and treated promptly. We present a case of an atypical presentation of unilateral AACG on post operative day (POD) 1, after a prolonged operation under general anaesthesia (GA).

Case presentation

A 65-year-old female underwent a 16 hour long operation for breast cancer and developed an altered mental status with a left fixed dilated pupil on POD 1. She was intubated to secure her airway in view of a depressed consciousness level and admitted to the intensive care unit. Initial blood investigations and brain imaging were unremarkable. On subsequent review by the ophthalmologist, a raised intraocular pressure was noted and she was diagnosed with acute angle closure glaucoma. She was promptly started on intravenous acetazolamide and pressure-lowering ophthalmic drops. Her intraocular pressure normalized in the next 24 hours with improvement in her mental status to baseline.

Conclusion

AACG needs to be consistently thought of as one of the top differentials in any post-operative patient with eye discomfort or abnormal ocular signs on examination. A referral to the ophthalmologist should be made promptly once AACG is suspected.
Fluids and Early Vasopressors in the Management of Septic Shock: Do We Have the Right Answers Yet?
Authors: Carlos Sanchez E. , Pinsky Michael R. , Sinha Sharmili , Mishra Rajesh Chandra , Lopa Ahsina Jahan , Chatterjee Ranajit
Published: August 2023

Septic shock is a common condition associated with hypotension and organ dysfunction. It is associated with high mortality rates of up to 60% despite the best recommended resuscitation strategies in international guidelines. Patients with septic shock generally have a Mean Arterial Pressure below 65 mmHg and hypotension is the most important determinant of mortality among this group of patients. The extent and duration of hypotension are important. The two initial options that we have are 1) administration of intravenous (IV) fluids and 2) vasopressors, The current recommendation of the Surviving Sepsis Campaign guidelines to administer 30 ml/kg fluid cannot be applied to all patients. Complications of fluid over-resuscitation further delay organ recovery, prolong ICU and hospital length of stay, and increase mortality. The only reason for administering intravenous fluids in a patient with circulatory shock is to increase the mean systemic filling pressure in a patient who is volume-responsive, such that cardiac output also increases. The use of vasopressors seems to be a more appropriate strategy, the very early administration of vasopressors, preferably during the first hour after diagnosis of septic shock, may have a multimodal action and potential advantages, leading to lower morbidity and mortality in the management of septic patients. Vasopressor therapy should be initiated as soon as possible in patients with septic shock.
Multi-criteria evaluation for parameter uncertainty assessment and ensemble runoff forecasting in a snow-dominated basin
Authors: Oğulcan Doğan Y. , Arda Şorman A. , Şensoy Aynur
Published: August 2023

The increase in global temperatures undesirably affects the ever-growing world population and reveals the significance of hydrology science. Hydrological models might estimate spatial and temporal variability in hydrological components at the basin scale, which is critical for efficient water resource management. Satellite data sets with enhanced snow mapping with high spatial and temporal resolutions have been developed. The potential of these satellite data sets is evaluated in this study for multi-criteria evaluation of a conceptual hydrological model to improve model performance and reduce uncertainty.

The upstream part of the transboundary Coruh River is selected for this study because snowmelt contributes a significant portion of the streamflow feeding major reservoirs during the spring and early summer months. The region’s snow cover dynamic has been analyzed using a combination of two satellite products. Hydrologic modeling is performed using the HBV model for the 2003–2015 water years (01 Oct–30 Sep). The Monte Carlo method is used for multi-criteria optimization exploiting satellite snow cover data besides runoff data. The sensitivity and uncertainty analysis on the model parameters indicate that multi-criteria calibration effectively reduces the uncertainty of the parameters and increases the model performance. Moreover, ensemble runoff forecasts are generated with several best model parameters using 1-day and 2-day lead time numerical weather prediction data for the snowmelt period (March–June) of the 2015 water year.

The results indicate that the use of multiple remote sensing products in combination better represents the snow-covered area for the region. Additionally, including these data sets into hydrological models enhances the representation of hydrological components while reducing runoff prediction uncertainty.
Output updating of a physically based model for gauged and ungauged sites of the Upper Thames River watershed
Authors: Jeevaragagam Ponselvi , Simonovic Slobodan P.
Published: August 2023

This study introduces a new ANN updating procedure of streamflow prediction for a physically based HEC-HMS hydrological model of the Upper Thames River watershed (Ontario, Canada). Besides streamflow and precipitation, the updating procedure uses other meteorological variables as inputs, which are not applied in calibration of the HEC-HMS model. All the results of performance measures on training, validation and test datasets for river gauges at Mitchell and Stratford revealed that the ANN updated models have performed better than the HEC-HMS model. The ANN model results were in excellent agreement with observed streamflow. The uncertainties can be associated with different input variables and different length of datasets used in the HEC-HMS model and the ANN model. The performance results suggest improvement in the RMSE values of the trained networks when additional meteorological data was used. The updated errors from the gauged sites of Mitchell and Stratford were used to update the streamflow values at the ungauged site of JR750 of the HEC-HMS model. While the underlying physical process in the ANN model consisting of interconnected neurons to map input-output relationships is not easily understood (in a form of mathematical equation), the HEC-HMS hydrological model can reveal useful information about the parameters of a hydrological process.
Effect of eucalyptus on blue and green water availability and discharge in the tropical highlands: An interpretation of available literature

Published: August 2023

The highlands serve as water towers for the blue water in the surrounding area, with often insufficient rainfall for rainfed crops. The population is growing in the highlands, changing the hydrology and blue and green water availability. One of the changes that affect the highlands of Ethiopia is the rapidly expanding areas of small patches of eucalyptus on farmers fields. This manuscript aims to sort through the limited available literature and develop a water balance model as a starting point to discuss how hydrology is affected by increased acreage of eucalyptus in the highlands. We find some evidence in the literature that patches of eucalyptus during the dry phase may withdraw water from the subsoil up to twice the rate of evapotranspiration when the soil water is not limited. Since saturation excess generates surface runoff in the subhumid and humid highlands, water withdrawn during the dry phase should be made up before the area with eucalyptus becomes hydraulically active. The amount of water that can be removed from storage by eucalyptus is greater in areas with a long dry monsoon phase than in temperate climates for the same increase in trees. We also found, as expected, that the eucalyptus water balance model, as developed in this paper, was not valid for areas in semi-arid and arid regions. Soil crusting and water repellency might induce infiltration excess runoff. A tentative implication is that since most blue water is produced in the areas with the highest rainfall, eucalyptus in subhumid and humid monsoon regions will affect the blue water supply downstream but not the plant available green water although shading will decrease yield in the immediate surroundings of the eucalyptus trees.
Camera-measured velocity distribution in laboratory open-channel flow with intense transport of bimodal combined-load
Authors: Svoboda Lukáš , Picek Tomáš , Matoušek Václav
Published: August 2023

An extended stereoscopic method, which identifies, and tracks particles based on their colour in solid-liquid flow, is tested for its capability to separately measure velocity distributions of particles of two fractions transported as bimodal sediment mixture in water flow through a laboratory flume. The principle of the tested method extension is a use of colour-based processing of images collected by two high-speed cameras which enables to filter out particles of one fraction from the image and leave particles of the other fraction in the image based on a selected colour hue range. The modified images are then processed by the original stereoscopic method to produce velocity distribution of particles of the individual fraction in the flow. The method extension is first tested in simple vertical flow carrying neutrally buoyant spherical particles of two distinct colours in a recirculation cell. In the next step, lightweight plastic particles of two fractions of different properties (size, shape, density) and colours are introduced to flow through a laboratory flume and velocity distributions of the two fractions are measured separately at flow conditions which mimic intense transport of bimodal combined-load in an open channel. Results exhibit a very good agreement with previous measurements with unimodal sediment in hydraulically similar flow.
Cognitive Ecologies of Presence(S) in Three Different Dance Forms
Authors: Pini Sarah
Published: August 2023

Presence is a central yet controversial topic in the study of performing arts and theatrical traditions, where the notion of ‘stage presence’ is generally understood as the performer’s ability to enchant the audience’s attention. How do dancers relate to the idea of presence in performance, and how do they understand, enact, and perform presence in their artistic work and practices?

In this article I offer an investigation into presence’s variations in three different dance practices and choreographic contexts: the case of the Ballet National de Marseille during the staging of Emio Greco’s piece Passione; Contact Improvisation in the case of independent groups of contacters in Italy and Australia; and Body Weather, a radical movement ideology developed by Japanese choreographer Min Tanaka in the context of the company Tess de Quincey and Co. in Sydney.

To illustrate how presence in dance practices emerges in relation to a complex and dynamic environment, I propose a cognitive ecological approach to the notion of ‘stage presence’, which considers both the co-presence of audiences and performers and the socio-cultural context of the performance event. By exploring how dancers articulate their lived experiences of presence in relation to their different dance contexts and traditions, I suggest framing phenomena of presence in an embodied ecological sense.
Equidistribution of Continuous Functions Along Monotone Compact Covers
Authors: Monfared Mehdi Sangani , Zhu Yihan
Published: August 2023

We give a necessary and sufficient condition for equidistribution of continuous functions along monotone compact covers on locally compact spaces. We show the existence of equidistributed mappings along Bohr nets arising from group actions. Using almost periodic means, we give an analogue of Weyl’s equidistribution criterion for continuous functions with values in arbitrary topological groups. We prove van der Corput’s inequality on the lattice ℕm for vectors in Hilbert spaces, and use this inequality to extend Hlawka’s equidistribution theorem to functions on the lattice ℕm (m ≥ 1) with values in arbitrary topological groups.

then it is important to choose the polynomial f “almost” at random. Goubin, Mauduit, and Sárközy presented some not very restrictive conditions on the polynomial f, but these conditions may not be satisfied if we choose a “truly” random polynomial. However, how can it be guaranteed that the pseudorandom measures of the sequence should be small for almost "random" polynomials? These semirandom polynomials will be constructed with as few modifications as necessary from a truly random polynomial.

En la crianza de peces nativos de la Amazonıá peruana como Colossoma macropomum, Piaractus brachypomus, Brycon amazonicus, Prochilodus nigricans y Arapaima gigas se utiliza alimento balanceado, en cuya formulación predomina la harina de pescado y otros insumos no locales. Esto, encarece y dificulta su adquisición, principalmente por los productores rurales amazónicos que se encuentran alejados del área urbana. Mundialmente, existen experiencias de alternativas para la crianza de peces en base al uso de vegetales, frutas e insectos, aprovechando la diversidad biológica del entorno. Así, el uso de larvas de insectos constituye una alternativa promisoria para el sector acuıć ola a escala global. El presente estudio muestra la cría en semicautiverio de Hermetia illucens “mosca soldado negra” utilizando residuos orgánicos (cítricos) colectados del área urbana y rural, destacando el uso de bagazo de naranjas y toronja. De esta forma utilizando, el principio de economía circular, se obtuvieron larvas vivas y harina de mosca soldado, las cuales podrán ser utilizadas para alimentar a peces de importancia comercial. Como producto final de la crianza de las larvas se obtuvo un compost orgánico ideal para sistemas agroforestales. Este estudio muestra una metodologıá barata, accesible y armónica con el ambiente para la crianza de mosca soldado negra en semicautiverio en la región de Loreto utilizando cıt́ricos del área urbana y rural.

Determination of Ideal Conditions for the Production of Hydroxyl Radicals through Spectroscopy of Ferric Thiocyanate and Methyl Orange
Authors: Maken Nirbaan
Published: August 2023

Exposure to radiation can lead to the breakdown of water into reactive oxygen species (ROS), such as hydroxyl radicals (OH·), through a process called radiolysis. The presence of hydroxyl radicals (OH·) and other ROS can cause mutations to DNA in the human body. While hydrogen peroxide (H₂O₂), a product of radiolysis, may not be a strong ROS on its own, it can react with certain metal ions such as iron(II) to produce hydroxyl radicals in a process called the Fenton reaction. This study investigates the optimal conditions for the Fenton reaction using a cost-effective spectroscopic analysis of ferric thiocyanate and degradation of methyl orange to detect the presence of Fe3+ and OH·. Understanding conditions and methods of detection for the Fenton reaction is relevant due to the carcinogenic nature of the hydroxyl radicals produced [1]. The results of the spectroscopic analysis suggest that the Fenton reaction occurs ideally in acidic environments (p = 0.00354) with low temperature dependence. Additionally, both spectroscopic methods are effective for detecting the efficiency of Fenton processes. This study provides valuable insights for future research on the Fenton reaction and its potential applications.
