METODE EKONOMSKE REGULACIJE U ELEKTROENERGETSKOM SEKTORU
Authors: Tomislav Gelo  , Ivona Štritof
Published: March 2023

Regulacija u elektroenergetskom sektoru javila se budući da se smatralo da mehanizam slobodnog tržišnog natjecanja, odnosno Smithova nevidljiva ruka1, neće djelovati na optimiranje tržišnih odnosa i zaštitu interesa potrošača kod prirodnih monopola kao što su prijenos i distribucija električne energije. Zbog navedenog, sve veći broj država odlučilo se zakonski urediti okvire i uvjete poslovanja prirodnih monopola u elektroenergetskom sektoru. Na taj način uvodi se regulacija elektroenergetskih djelatnosti koja za cilj ima zaštitu kako interesa potrošača tako i investitora, kroz zaštitu uloženog kapitala, kao i postizanje okruženja koje vlada u uvjetima potpuno slobodnog tržišnog natjecanja. Ujedno, da bi se postigla neovisnost i transparentnost procesa, države osnivaju regulatorna tijela koja na nepristran i razvidan način uređuju odnose između svih uključenih strana. U ovom radu daje se pregled osnovnih metoda ekonomske regulacije koje se primjenjuju u državama Europske unije (15), te se ističu prednosti i nedostaci svake od njih. Ujedno daju se smjernice i preduvjeti za primjenu ekonomske regulacije u elektroenergetskom sektoru u Republici Hrvatskoj.

Published: March 2023

El objetivo del presente estudio fue identificar la relación que existe entre los estilos de crianza positivos y las tendencias de conductas prosociales en adolescentes. Se realizó un estudio metodológico cuantitativo, transversal, de diseño no experimental basado en un modelo descriptivo y correlacional. La muestra estuvo conformada por adolescentes de la ciudad de Cuenca, entre 13 a 17 años y sus padres de familia. Para la recolección de datos  se utilizaron los instrumentos PTMR y E2 P V.2. En los resultados se logró identificar que existe correlación positiva directa entre los estilos de crianza positivos y las tendencias de conductas prosociales. Los análisis mostraron también que todos los estilos de crianza se relacionan directamente con la conducta prosocial emocional e inversamente con la conducta altruista. La investigación concluyó que la crianza positiva promueve el desarrollo socioemocional y, por lo tanto, la presencia de conductas sociales adecuadas en los adolescentes.

FLUORIDE AND CHILDREN’S HEALTH IN INDIA: DISTRICT LEVEL ANALYSIS
Authors: Aggarwal Khushboo , Ahmad Nadeem
Published: March 2023

Quality issues in water such as presence of high levels of arsenic, nitrates, iron, salinity and fluoride has been witnessed in various parts in India. Presence of fluoride at alarming levels has led to severe threat to human survival. Prolong consumption of contaminated water with an unsafe fluoride level can lead to many diseases. Therefore, using the exogenous variation in fluoride across districts, we try to assess the impact of fluoride contaminated water on health outcomes particularly for children; dental and skeletal diseases. Usingnationally representative dataset for India, greater exposure to fluoride contamination is associated with adverse health outcomes amongst school going children. Our findings suggest that an additional increase in fluoride contamination leads to higher risk of dental (odds ratio-1.196) and skeletal diseases (odds ratio-1.206). Moreover, the intensity and incidence of such diseases (dental-1.398 and skeletal diseases-1.494) has increased drastically over time. Our estimates are also robust to district and time fixed effects. Our findings also suggestchildren who belong to the age group of 7-14 years of age experience such adverse health outcomes relatively more than those who belongs to 0-6 years of age, owing to visibility of fluoride related symptoms at later stages in life. Uniformity of our results holds even after using an alternative measure of estimation, Propensity Score Matching.

Authors: Patel Roshni , Maitreya Bharat
Published: March 2023

In order to be healthy, plants often require a constant flow of nutrients. Any nutritional shortfall leads to the development of nutrient deficiency symptoms. Metal can be considered of as a nutrition for plants. When the nutrient supply exceeds the necessary levels, plants may suffer damage, and in rare situations, excessively high levels of nutrition loaded with heavy metals may even result in plant death. The presence of Micronutrients in small quantities is responsible for healthy growth and development of plants. This paper focuses on the analysis of micronutrients through DTPA –CaCl2-TEA method present in the soil collected from Morbi region. Fifteen samples from different villages of Morbi region were collected in which the micronutrients like Zinc, Iron, Copper and Manganese were analyzed. According to the data, Sajjanpur has the highest and lowest concentrations of copper, whereas Jetpur and Ghuntu have the highest and lowest concentrations of zinc, respectively. In a similar manner, significant levels of Fe have been found in Jambudiya, while Mn levels in Dharampur are also somewhat elevated. Jasmathgadh has a lower concentration of Fe and Mn than other villages. The concentration ratio has a direct impact on soil fertility and is related to crop output, crop production, and plant health.

Authors: de A Santos Jailson , Ribeiro Fabio OS , Bezerra Roosevelt DS , da Silva Durcilene A , Liarte Daniel B
Published: March 2023

The process of bacterial transformation results from the introduction of specific genetic material into bacteria cells and subsequent gene expression. This technology has significant applications in gene cloning technology, and allows new possibilities for genetic breeding. The use of cellulose and babassu mesocarp to improve the process was not found in the literature. Thus, the objective of this work was to evaluate the effect of biopolymers (cellulose and biopolymer rich in starch extracted from the babassu mesocarp) on the efficiency of this process. The biopolymers were characterized by XRD, FTIR, zeta potential, thermal analysis, agarose gel electrophoresis and DLS. The transformation was carried out using the plasmid pGEM and E. coli. It was investigated the cytotoxicity and the effect of different concentrations of the materials and plasmid DNA on the transformation. The study demonstrated that 0.050 mg/mL of both materials increased the efficiency of bacteria transformation, and small amount of DNA combining with the biopolymers allowed obtaining satisfactory results. Therefore, the biopolymers can be used in genetic studies involving the transfer of DNA into bacterial cells.

Published: March 2023

Biodiesel production has been studied using non-edible seed oil from Thevetia peruviana. The non-edible oil from Thevetia peruviana seed could be used as a feedstock for biodiesel manufacturing. In this paper, the production of biodiesel utilizing Thevetia peruviana Seed Oil (TPSO) has been investigated. The ripe seeds of Thevetia peruviana were gathered from China and Pakistan, and after drying, its oil was extracted using the Soxhlet procedure. The seeds' highest oil content was discovered to be between 48-62%. Investigations were done into the TPSO's physicochemical characteristics. Transesterification was used to make biodiesel. The methanol to oil molar ratio, the duration, temperature, rate of stirring, and the amount of catalyst loaded were all studied in order to optimize the biodiesel synthesis process and get the highest yield. Under the ideal conditions, which included a methanol-to-oil molar ratio of 6:1, a catalyst loading of 0.42 weight percent, a temperature of 70°C, a stirring rate of 700 rpm, and an 80-minute reaction period, the biodiesel yield was 98.4%. Gas Chromatography (GC) analysis was used to identify the fatty acid configuration of the oil. Nuclear Magnetic Resonance Spectroscopy (NMR, 1H NMR and 13C NMR) and Fourier Transform Infrared Spectroscopy (FTIR) were used to characterize the biodiesel product. The ASTM & EN test technique were used to determine the biodiesel's fuel characteristics. Thevetia peruviana seed oil is used to make biodiesel that satisfies the requirements of ASTM D6751 and EN standards. As a result, this seed oil is a possible feedstock for the production of biodiesel.

Authors: K Srinivasa Kishore  , K Venkata Subbaiah
Published: March 2023

Lightweight materials have recently received much attention for the fabrication of various components for industrial usage, particularly in the automotive and aerospace fields. Nowadays, though, recycling epoxy-based composite at the end of its life is very complicated but due to its lightweight and enhanced properties "fiber-reinforced" epoxy based polymer composites are most preferred materials instead of conventional heavy metals. The composites based on epoxy resins reinforced with high-performance fibers such as carbon fiber (CF) are in extensive use for industrial and structural applications. Moreover, Thermoplastics are less expensive, simple to work with and simple to recycle but they can’t give desired properties like Thermosets. The current study encompasses about CF and multiple attempts done over the decades to enhance the mechanical attributes of CF-reinforced thermo-set (epoxy) based composites and to understand the part of many parameters on their performance.

Perpetuating Victimization with Efforts to Reduce Human Trafficking: A Call to Action for Massage Therapist Protection
Authors: Rosenow Mica , Munk Niki
Published: March 2023

Human trafficking guised as massage therapy businesses is a highly successful business model that creates independent but related victims beyond the women and girls forced into sex work. Massage clinicians and the massage therapy profession are also negatively impacted by the trafficking massage business model with over 9,000 established illicit massage businesses marketing services alongside professional therapeutic massage businesses. Credential regulation efforts advocated for by various massage-related professional organizations and regulat-ing agencies have fallen short in their purported intentions to protect massage therapists and trafficking victims. Massage industry advocates continue endorsing massage therapy as a branch of health care although healthcare workers are not generally considered or treated as sex workers. Sexual harassment research in direct patient care disciplines, such as physical therapy and nursing, points to a high patient initiated incident rate and transdisciplinary, detrimental mental health outcomes for clinicians. Reporting and debriefing instances of sexual harassment inside of healthcare organizations, covered by The Civil Rights Act of 1964, promotes a victim-centered perspective to support the well-being of past, current, and pending victims. The massage therapy workforce is comprised of mainly female sole proprietors, creating a double vulnerability in their potential to experience sexual harassment. This threat is compounded by little-to-no protective or supporting systems or networks for massage clinicians. The priorities of professional massage organizations to depend on credentialing and licensing as their primary efforts to fight human trafficking, seems more to perpetuate the current system/expectations, leaving individual massage therapists responsible for fighting or reeducation deviant sexualized behaviors. This critical commentary closes with a call to action aimed at professional massage organizations, regulators, and corporations to protect massage therapists through a unified position, supported in word, policy, and action, against sexual harassment, and unequivocally condemns professional massage devaluation and sexualization in all forms.
Localizing Sources of Variability in Crowded TESS Photometry
Authors: Higgins Michael E. , Bell Keaton J.
Published: March 2023

The Transiting Exoplanet Survey Satellite (TESS) has an exceptionally large plate scale of 21″ px−1, causing most TESS light curves to record the blended light of multiple stars. This creates a danger of misattributing variability observed by TESS to the wrong source, which would invalidate any analysis. We developed a method that can localize the origin of variability on the sky to better than one fifth of a pixel. Given measured frequencies of variability (e.g., from periodogram analysis), we show that the best-fit sinusoid amplitudes to raw light curves extracted from each pixel are distributed in the same way as light from the variable source. The primary assumption of this method is that other nearby stars are not variable at the same frequencies. Essentially, we are using the high frequency resolution of TESS to overcome limitations from its low spatial resolution. We have implemented our method in an open-source Python package, TESS_localize (github.com/Higgins00/TESS-Localize), that determines the location of a variable source on the sky and the most likely Gaia source given TESS pixel data and a set of observed frequencies of variability. Our method utilizes models of the TESS pixel response function, and we characterize systematics in the residuals of fitting these models to data. We find that even stars more than three pixels outside a photometric aperture can produce significant contaminant signals in the extracted light curves. Given the ubiquity of source blending in TESS light curves, verifying the source of observed variability should be a standard step in TESS analyses.

The Transiting Exoplanet Survey Satellite (TESS) mission searches for new exoplanets. The observing strategy of TESS results in high-precision photometry of millions of stars across the sky, allowing for detailed asteroseismic studies of individual systems. In this work, we present a detailed asteroseismic analysis of the giant star HD 76920 hosting a highly eccentric giant planet (e = 0.878) with an orbital period of 415 days, using five sectors of TESS light curve that cover around 140 days of data. Solar-like oscillations in HD 76920 are detected around 52 μHz by TESS for the first time. By utilizing asteroseismic modeling that takes classical observational parameters and stellar oscillation frequencies as constraints, we determine improved measurements of the stellar mass (1.22 ± 0.11 M
⊙), radius (8.68 ± 0.34 R
☉), and age (5.2 ± 1.4 Gyr). With the updated parameters of the host star, we update the semimajor axis and mass of the planet as a = 1.165 ± 0.035 au and

With an orbital pericenter of 0.142 ± 0.005 au, we confirm that the planet is currently far away enough from the star to experience negligible tidal decay until being engulfed in the stellar envelope. We also confirm that this event will occur within about 100 Myr, depending on the stellar model used.
Description and distribution of three morphotypes of the Eucyclops serrulatus group (Crustacea, Copepoda, Cyclopoida) from Algerian water bodies
Authors: Akli-Bidi Safia
Published: March 2023

Examination of Eucyclops populations coming from Algerian water bodies and identified as Eucyclops cf. serrulatus showed three morphotypes, based on morphometric characters and microcharacters. Morphotype 1 was the most abundant, collected in the east and the west of Algeria. Morphotype 2 was sampled in the south of the country, characterised by posterolaterally elongated thoracic segments and the fourth thoracic segment bearing cilia on its lateral angles. Morphotype 3 was found in a small temporary pond in the north of the country and was the smallest one. Other differences were observed on surface microcharacters of antenna basipodite, coxopodite and intercoxal plate of the fourth leg. The characters of the most widespread morphotype (morphotype1) were stable in all localities despite the fact that these were located in two geographically separated regions (eastern and western Algeria).

While scarce resource allocation has been discussed due to the demands the COVID-19 pandemic has placed on the healthcare system, diagnostic testing has not been conceptualized as a scarce resource. SARS-CoV-2 diagnostic testing was limited in the early phases of the pandemic, narrowing access to priority groups recommended by the Centers for Disease Control and Prevention (CDC). The early lack of testing led to the utilization of community mitigation strategies as primary prevention. The resulting work and school closures came at a serious economic and educational cost, particularly for underserved populations. Testing guidelines have contributed to inequities in how the pandemic has affected vulnerable populations, including people experiencing homelessness, inmates, and frontline essential workers. Testing should be ethically allocated to maximize population benefits, minimize harms, and mitigate the inequities the pandemic has highlighted. This discussion on the ethical implications of rationing diagnostic testing as a scarce resource will hopefully inform guidelines in future pandemics.
A Report of Polymorphous Toxic Erythema of Chemotherapy During Treatment with Enfortumab Vedotin for Metastatic Urothelial Cell Carcinoma
Authors: Bledea Ramona , Scharnitz Thomas
Published: March 2023

Enfortumab vedotin (EV) is a novel drug targeting solid tumors expressing Nectin-4, such as metastatic urothelial carcinoma (mUC). While trials have supported its efficacy, there have also been early reports of cutaneous toxicity that have not yet been well characterized. Here, we report a case of a 60-year-old male who presented with burning, erythematous, and edematous plaques after receiving one cycle of EV as part of a Phase III clinical trial for treatment of his mUC. After a sixth cycle of treatment, he developed pruritic, erythematous, and hyperkeratotic papules with scattered tense vesicles across his extremities and trunk. These eruptions contain features suggestive of toxic erythema of chemotherapy (TEC). The first eruption resolved promptly with topical triamcinolone, whereas the second eruption required both topical triamcinolone and prednisone 1 mg/kg/day and resolved more slowly across 3 weeks. Although the two presentations had different morphologies, both can be described histologically as TEC. We therefore propose that one potential cutaneous eruption from EV therapy can be TEC and that it may have polymorphous presentations both across patients and within the same patient.

Published: March 2023

Technological innovations in the financial sector are transforming the provision of financial services. Fintech is one such innovation that not only provides opportunities (such as financial development and inclusion) but also brings various potential risks to consumers and investors. These risks also threaten the stability and integrity of global financial system. As such, financial regulators across the globe are adjusting their regulatory regimes and continue to provide and develop guidelines to mitigate these risks. This study provides a cross-country review of fintech policy responses of developed world.
Unpacking Central Bank Digital Currency (CBDC) Implementation Challenges and Risks
Authors: Ahiabenu Kwami
Published: March 2023

This chapter outlines the risks and challenges involved in implementing central bank digital currency (CBDC). Interest in CBDC is currently growing, with a number of central banks paying it serious consideration, and a number of countries are implementing or piloting CBDC. Although CBDC holds a great deal of promise, its implementation is not without difficulty. This chapter highlights the major implementation issues, such as CBDC contributing to financial exclusion, technology risks, CBDC's inability to work in an offline environment, lack of privacy, and confidential consideration, since anonymity is difficult to achieve. The chapter concludes by highlighting the need to deploy CBDC with greater attention paid to societal, economic, and political factors instead of a purely technocratic approach.
Philosophy in Prison
Authors: Abenoza Sira , Gimeno Claudia
Published: March 2023

This chapter is centred around the elective course “Philosophy in Prison” offered to last-year law students of ESADE Business and Law School in Barcelona, Spain. It is taught inside a Catalan prison, and the participants are, in equal numbers, law students from the university and imprisoned people from a penitentiary centre. During 10 weekly sessions the group engages in a dialogical exploration around topics essential to human existence such as identity, happiness, justice, or forgiveness. The mainstream law education provides young students a purely theoretical and partial understanding of the law, which reinforces the harmful prejudices about incarcerated people and other minorities embedded in the judicial system they will represent. This chapter dives into why Socratic Dialogue is an extremely efficient method to instil in the future lawyers a commitment to social justice and inclusion, essential components for healthy, just, and thriving democracies.

Immuno-oncology marked a therapeutic revolution in the treatment of cancer. Thanks to the new strategy that aims to awaken the immune system to fight cancer cells, there has been a change in the clinical course in the treatment of advanced Non- Small Cell Lung Cancer (NSCLC). Our study aimed to evaluate the therapeutic efficacy of nivolumab monotherapy in the treatment of patients with advanced stage IIIB/IV non-small cell lung cancer beyond the second line. The results showed a progression-free survival of 7.35 months and an improvement in the quality of life of patients compared to other treatments. In addition, no type 3 and type 4 adverse reactions were detected in patients treated with Nivolumab. We hope that these results, already promising, will lead to an increase in overall survival in the future.
Barriers to the provision of smoking cessation intervention/services: A mixed-methods study among health care workers in Zambezi region, Namibia

Published: March 2023

Background:  Healthcare workers (HCWs) can play a significant role in tobacco prevention by delivering smoking cessation (SC) interventions to patients who smoke. Objective:  To identify and explore the perceived barriers which prevent healthcare workers from delivering SC counselling to patients in Zambezi region, Namibia. Methods:  A regional-based, concurrent mixed-methods study was conducted between March and October 2020 among HCWs of the 8 constituencies of Zambezi region, Namibia. In the study, 129 respondents, who had been residents of the selected constituencies for over 5 years and aged between 17 to 60 years, participated. Results: 129 respondents participated in the study. Majority of respondents were females (62.9% and 68.1%) compared to (37.1% and 31.9%) males. The mean age of respondents was 35.91 (SD=9.3) and 36.61 (SD=8.7) respectively and their ages ranged between 18 and 59 years. Key barriers were identified: (i) HCWs- based barriers included lack of time to provide SC, inadequate training and insufficient knowledge on SC interventions; (ii) sys- tem-based barriers identified lack of SC guidelines and educational materials for patients, and specialists to refer patients; and (iii) patient/client-based barriers included lack of patient interest in SC information, patients not adhering to advise given on SC. Conclusions:  This study showed that SC delivery in Zambezi region is inadequate. Barriers were identified regarding the delivery of SC intervention for the first time. Targeted SC interventions are required to combat these identified specific barriers. There is a crucial need to improve HCWs skills and knowledge in providing SC intervention.

Background: Cardiovascular disease remains the leading cause of death worldwide. Hypertension is a primary risk factor for the development of cardiovascular disease and affects more than a quarter of the global adult population. Africa is a continent where the prevalence of non-communicable diseases including cardiovascular disease and hypertension, is increasing rapidly. Botswana is a developing country in Sub-Saharan Africa. In such contexts the early identification of hypertension, through community screening initiatives, is an important tool for the management of cardiovascular disease in the population. Objective: To investigate and describe the prevalence of hypertension in a sample of community members residing in a low-income peri-urban setting in Gaborone, Botswana. Method: 364 adult participants had their blood pressures measured during a community health screening exercise. The values were analysed and categorised using the American Heart Association classification scale as either being normal, elevated, hypertensive stage 1 or hypertensive stage 2. Results: 234/364 (64%) of participants were found to have blood pressures within normal limits. 53/364 (15%) had elevated blood pressures, 57/364 (16%) were in hypertensive stage 1 and 20/364 (5%) were in hypertensive stage 2.Conclusions: Hypertension in Africa is a growing concern. Botswana appears to be no exception with a 36% prevalence of abnormal blood pressures being recorded. However, the majority of these were classified as elevated or stage 1. Early identification and treatment of hypertension in these early stages can significantly decrease the risk of developing stage 2 hypertension and the related systemic complications.

Authors: Vankudre Gopi S. , Al Saadi Sheikha
Published: March 2023

Background: Diabetic retinopathy (DR) contributes 1% of the total 37 million blind individuals globally. In Oman, 12.3% of the community aged 18 years and older are affected by diabetes mellitus. Health literacy is essential in advancing an individual’s disease-linked knowledge, attitudes and treatment compliance. Effective educational resources would earn positive health outcomes.Aim: This study evaluates the Omani community’s perception of educational resources related to DR.Setting: This is a prospective, cross-sectional, questionnaire-based study.Methods: A self-administered, online questionnaire received responses from 253 participants using a convenient snowball sampling approach. The initial section of the questionnaire gathered information on participant’s demographic information. The second section collected the feedback on the perception of the availed DR material utilising a five-point Likert scale. Descriptive and inferential (chi-square test, Fisher’s exact test and logistic regression analysis) statistics were used to analyse the data.Results: Of the total 253 study participants, 51 (20.2%) were male and 202 (79.8%) were female. Only 155 (61.3%) participants received DR-related health information. Optometrists (30.3%) served as the primary source of information. There was no relationship between perception and socio-economic or educational levels (p  0.05). Of the 155 participants receiving DR-related health information, 47.7% (n = 74) of the survey population is highly satisfied with the received DR-related health promotional resource.Conclusion: Only 61.3% of the members received DR-related health information. Most participants had a positive perception of DR-related health educational resources.Contribution: This study observed positive participant’s perception towards diabetic retinopathy related health educational resources. The study proposes to conduct further health promotional activities using social media platforms.
