Vpliv konsolidirane davčne osnove davka na dohodek pravnih oseb na podpisane davčne pogodbe med tretjimi državami
Authors: Kovač Matjaž
Published: January 2024

Uvedba konsolidirane davčne osnove davka na dohodek pravnih oseb (CCCTB) v EU je odgovor na izziv evropskega gospodarskega povezovanja. Prispevek obravnava analizo okvira CCCTB za preprečevanje dvojnega obdavčevanja in za zaščito skupne konsolidirane davčne osnove ter njen vpliv na že podpisane davčne pogodbe. V praksi je bilo ugotovljeno, da uvedba davčnega odtegljaja za plačila hčerinskih družb s sedežem v tujini matični družbi iz tretje države po običajni davčni stopnji (stopnja neobdavčene pogodbe) krši pogodbene določbe, enakovredne drugemu odstavku 10. in 11. člena ter prvemu odstavku 12. člena Modela OECD. Dodelitev dohodka stalni poslovni enoti v EU, ki je v lasti tretje države, na podlagi prerazporeditvenega mehanizma CCCTB, je v nasprotju z drugim odstavkom 7. člena Modela OECD. Klavzula o varčevanju z davki, ki obstaja v davčnih pogodbah, sklenjenih med državami članicami CCCTB in tretjimi državami v razvoju, bi lahko bila problematična pri porazdelitvi »navideznega« kredita.
Pravilo obrestne omejitve - Direktiva EU o določitvi pravil proti praksam izogibanja davkom, ki neposredno vplivajo na delovanje notranjega trga
Authors: Kerin Marko
Published: January 2024

S 1. 1. 2019 so bile nekatere države članice EU zavezane implementirati pravilo obrestne omejitve na podlagi Direktive proti izogibanju davkom (ATAD), druge države članice, vključno s Slovenijo, s primerljivo učinkovitim pravilom tanke kapitalizacije, pa morajo to napraviti najkasneje do 1. 1. 2024. Namen prispevka je obravnavati pravne dileme na ravni EU v zvezi s pravilom obrestne omejitve, zlasti z vidika njegove skladnosti s primarnim pravom EU. Članek osvetli problematiko preko sodne prakse Sodišča EU. Prikaže tudi potencialno neustavnost pravila obrestne omejitve v Nemčiji. V zadnjem delu najprej proučim sodbe slovenskih sodišč v zvezi s tanko kapitalizacijo. Sledi pregled slovenskih sodb v zvezi z davčnim načelom plačila davka na podlagi ekonomske sposobnosti in objektivnega neto načela. Na podlagi analize sodb Ustavnega sodišča RS lahko sklenemo, da bo z implementacijo pravila obrestne omejitve tudi v Sloveniji takšno pravilo diskriminiralo davčne zavezance. V zaključku prispevka je podanih nekaj predlogov zakonodajalcu.
Protipravno pridobljeni dokazi v luči ustavnih procesnih jamstev
Authors: Drnovšek Katja
Published: January 2024

V slovenskem pravnem redu uporaba protipravno pridobljenih dokazov v pravdnem postopku ni normativno urejena, zato so se rešitve razvile v sodni praksi, ki to vprašanje naslavlja skozi prizmo reševanja kolizije ustavnih pravic. Prispevek se osredotoča na pomanjkljivosti ureditve, ki izhajajo iz odločbe Ustavnega sodišča RS kot edine pravne podlage za odločanje o dopustnosti dokazov, pridobljenih s kršitvami ustavno varovanih pravic. Obravnava teoretične vidike presoje dopustnosti protipravno pridobljenih dokazov v kontekstu ustavnih procesnih jamstev ter relevantno sodno prakso, v kateri se te težave odražajo. Posebna pozornost je posvečena pomenu pravice do dokaza, metodološkemu pristopu, ki naj se uporabi pri tehtanju pravic, ter argumentom, na podlagi katerih sodišča utemeljujejo svoje odločitve o dopustnosti dokazov. Prispevek kot najustreznejšo metodo za razreševanje kolizije pravic predlaga metodo praktične konkordance, hkrati pa opozarja na potrebo po poenotenju sodne prakse ob uporabi kriterijev, ki upoštevajo tako pravico stranke do dokaza kot tudi osebnostne pravice nasprotne stranke.
Umestitev elektronskih dokazov med dokazna sredstva pravdnega postopka
Authors: Zahrastnik Kristjan
Published: January 2024

Svojevrstna narava elektronskih dokazov botruje k temu, da jih ne moremo jasno in enostavno umestiti med eno izmed vrst tradicionalnih dokaznih sredstev, ki jih predvideva Zakon o pravdnem postopku (ZPP). Elektronski dokazi so po svoji naravi zapisani na elektronskem nosilcu in so tako v izvorni obliki neberljivi, zaradi česar se za izvedbo dokaza elektronske narave zahteva ustrezno znanje in uporaba tehnoloških pripomočkov. Ker trenutna normativna ureditev dokaznih pravil v ZPP posebej ne ureja posebnosti elektronskih dokazov, se elektronske dokaze po analogiji umešča med tradicionalna dokazna sredstva pravdnega postopka. Med katera dokazna sredstva se umeščajo, ZPP ne daje izrecnega odgovora. Vsled temu je namen prispevka proučitev, med katera dokazna sredstva umeščamo najpogostejše vrste elektronskih dokazov in ali je trenutna ureditev glede na svojevrstnost elektronskih dokazov ustrezna.
Videokonferenca kot instrument ustne obravnave v sodnem postopku ter njen poseg v načelo neposrednosti
Authors: Šmigoc Matej
Published: January 2024

V civilnih in kazenskih postopkih se lahko vloge pri sodišču vlagajo v elektronski obliki, na narokih lahko stranke in ostali udeleženci sodelujejo z uporabo videokonference, sodišča pa lahko svoje odločbe vročajo po elektronski poti. Namen vodenja postopkov na tak način je v zagotovitvi njihove hitrosti in ekonomičnosti, ustrezna zakonska podlaga pa je sodiščem na voljo že dalj časa. Ukrepi zaradi preprečevanja širjenja virusne bolezni COVID-19 so napredek na tem področju pospešili, predvsem z možnostjo uporabe videokonference, ki sodišču omogoča izvedbo glavnih obravnav ter zaslišanj strank, prič in izvedencev brez njihove fizične navzočnosti v razpravnih dvoranah. Zato je zaradi psihološkega vidika izvedbe dokazov z uporabo videokonference in vpliva neverbalnega vtisa zaslišane osebe na sodnikovo zaznavanje, posebno pozornost treba nameniti spoštovanju temeljnih načel, še posebej načelu neposrednosti. Odgovore na vprašanja, ki se v zvezi z uporabo videokonference v sodnem postopku postavljajo, pa je treba iskati z interdisciplinarnim in primerjalnopravnim pristopom.
Ugotovitvena tožba v sporih o prenehanju delovnega razmerja s primerjalnopravnim poudarkom na nemški ureditvi
Authors: Ciraj Nataša
Published: January 2024

Najpomembnejša procesna vidika uveljavljanja varstva zoper prenehanje pogodbe o zaposlitvi sta pravočasno uveljavljanje sodnega varstva pred delovnim sodiščem in ustrezna vrsta tožbe oz. vsebina tožbenega zahtevka. V slovenski sodni praksi se je pred časom izpostavila dilema o najustreznejši vrsti tožbe v sporih o odpovedi pogodbe o zaposlitvi. Odgovore na ključna vprašanja ponuja primerjalnopravni pregled značilnosti ugotovitvene tožbe v nekaterih tujih pravnih redih s poudarkom na nemški ureditvi, ki ima s slovensko ureditvijo na področju varstva zoper odpoved pogodbe o zaposlitvi največ skupnih značilnosti. Odklanjanje ugotovitvene tožbe v sporih o varstvu zoper odpoved pogodbe o zaposlitvi predstavlja negotovost in hkrati nevarnost, ki lahko vodi v zmanjšanje varstva zoper nezakonito odpoved. Zaradi oblikovalnega učinka odpovedi in njenih posledic je za varstvo zoper odpoved pogodbe o zaposlitvi najprimernejša na prekluzivni rok vezana ugotovitvena tožba, ki lahko zadosti zahtevam pravne varnosti ter zahtevam prednostnega in hitrega reševanja tovrstnih delovnih sporov.
Kibernetska varnost in prekrški s področja kibernetske varnosti
Authors: Primec Andreja , Tičar Bojan
Published: January 2024

Kibernetska varnost je presegla okvirje informatike in zajema že vsa področja družbenega življenja. Vendar poleg ugodnosti, ki jih prinaša digitalizacija, le-ta predstavlja tudi nevarnost zlorabe elektronskega informacijskega potenciala. V Sloveniji ima pravica do kibernetske varnosti ustavne pravne podlage, sama informacijska varnost kot ožji del kibernetske pa je urejena v uredbah in direktivah EU. Kibernetska varnost igra ključno vlogo v delujoči ureditvi varnega pretoka informacij, integriteti celotnega informacijskega sistema in v preprečevanju zlorab pri uporabi digitalnih informacij. Pravna ureditev kibernetske in informacijske varnosti pomeni zagotavljanje ustreznega normativnega okvira, ki pravno omogoča nemoteni pretok elektronskih informacij brez nepooblaščenega dostopa tretjih, kakor tudi varuje uporabnike pred zlorabo ali uničenjem le-teh. Kibernetska varnost vključuje zaupnost, integriteto in dostopnost informacij, pa naj bodo le-te v digitalni, tiskani obliki ali kakšni drugi obliki. Poleg tega prispevek predstavlja analizo pravne ureditve predpisovanja in sankcioniranja prekrškov na področju kibernetske oz. informacijske varnosti z vidika sodobne slovenske informacijske zakonodaje.

Multimodal Neurophysiological Representations of High School Students’ Situational Interest: A Machine Learning Approach
Authors: Liu Xiaobo , Ye Jingmeiqi , Zhang Yu
Published: January 2024

Interest plays a vital role in students’ learning performance. Accurately measuring situational interest in the classroom environment is important for understanding the learning mechanism and improving teaching. However, self-report measurements frequently encounter issues of subjectivity and ambiguity, and it is hard to collect dynamic self-report scales without disturbance in the naturalistic environment. Thanks to the development of neuroscience and portable biosensors, it has become possible to represent psychological states with neurophysiological features in the classroom environment. In this study, multimodal neurophysiological signals, including electroencephalograph (EEG), electrodermal activity (EDA), and photoplethysmography (PPG), were applied to represent situational interest under both laboratory (Study 1) and naturalistic (Study 2) paradigms. A total of 33 features were extracted, and 7 different statistical indicators were calculated for each of them across all the epochs. Among these features, 47 in Study 1 and 49 in Study 2 demonstrated significant correlation with self-report situational interest. Employing a machine learning model, the analysis yielded a mean absolute error (MAE) of 0.772 and mean squared error (MSE) of 0.883 for the dataset in Study 1. However, the model was not robust on data from Study 2. These findings offer empirical support for the conceptual framework of situational interest, demonstrate the potential of neurophysiological data in educational assessments, and also highlight the challenges in naturalistic paradigm.

Published: January 2024

The excess supply of shallots due to the increase in harvest area in Indonesia in 2019-2020 resulted in a gap between supply and demand, resulting in price fluctuations over time. The price fluctuations that occurred plus the covid-19 pandemic in early 2020 caused low purchasing power and reduced household consumption. The study aims to determine the effect of prices and the Covid-19 pandemic on the demand and supply of shallots in Indonesia. The data used is time series data. Data analysis using multiple linear. The results showed that the demand for shallots in Indonesia increases every year because this commodity is always needed every day, but the demand for shallots is not matched by stable and evenly distributed production in each region every month. Prices and the covid-19 pandemic affect the demand for shallots in Indonesia significantly and significantly, there are also other factors, namely chili prices which have a negative effect on demand, and per capita income which has a positive effect on demand. Prices and the covid-19 pandemic partially have no significant effect on shallot supply in Indonesia. The variable that has the strongest influence on shallot supply in Indonesia is the harvest area variable.

Published: January 2024

The SDGs emphasize the need to end hunger, improve nutrition and achieve food security. Meeting food needs occurs when everyone has physical and economic access to sufficient, safe and nutritious food. Lampung Province is a province that is a production center for rice, cassava, and corn. This shows that there is the ability of Lampung Province to provide food for its inhabitants. However, regional food availability at the macro level does not guarantee household food security at the micro level. This study uses Susenas raw data for Lampung Province in 2022. Food security status is measured based on a combination of the share of food expenditure and the level of energy consumption which adopts the Jonsson and Toole (1991) indicators to see the effect of several household variables. This study uses ordinal logit regression where the categorization of status is divided into four, namely food insecurity, food deprivation, food vulnerable, and food security. As much as 41,54 percent of households are food secure and 9,5 percent are food insecure. Based on ordinal logit regression analysis, the researchers concluded that the variables affecting household food security in Lampung Province were cigarette consumption, access to credit, social assistance, land assets, internet use, place of residence, income, number of household members, whether the household works on agriculture or not, and age head household.

Implementation of Good Agriculture Practice (GAP) in coffee farming as an effort to increase productivity. However, many farmers do not apply good cultivation techniques in their farming activities. research aims to analyze the relationship between knowledge, attitudes, and actions of farmers in implementing GAP. The method used was a survey and sampling technique using non-probability sampling (saturated sampling) of 120 Arabica coffee farmers in Lembah Gumanti and Pantai Cermin Districts, Solok Regency. Data were analyzed quantitatively using descriptive statistics from the results of frequency distribution tables and correlation analysis using Spearman Rank correlation test calculations. The analysis results show that farmers' knowledge of implementing GAP is high, and farmers' attitudes are quite good, while farmers' actions in implementing GAP are in the inappropriate category. Correlation analysis shows a significant relationship (significance 0.05) between knowledge, attitudes, and attitudes towards farmer actions (p= 0.00). There is no significant relationship between knowledge and action (p=0.974). In implementing GAP, farmers need to be given continuous counseling so that their attitudes and knowledge improve and farmers have high motivation to implement GAP.

Embodying Milpa: Centering Place to Cultivate Polycultures of Reciprocity in Learning Environments
Authors: Gallardo Daniel
Published: January 2024

Milpa is an ancestral agriculture technique that has been passed down by Indigenous communities in so-called North America for millennia through stories of place. As an Indigenous knowledge system that is based on the symbiotic cultivation of diverse species, learning from milpa gifts lessons to cultivate polycultures of reciprocity. Drawing from my lived experience as a Mestizx educator from Mexico, I propose embodying milpa in learning environments as a horizon of possibility to refuse and disrupt the ways in which education has been limited, standardized, controlled and confined to colonial monocultures (Shiva, 1993). I use the cultivation of milpa as a metaphor to represent the transformation of modernist education systems that prioritize individuality and rationality shifting towards collaborative learning environments that are complex, messy and entangled with the land. Late Indigenous Professor Michael Marker (2018) invites scholars to center place as the beginning point of inquiry when excavating the specific effects of colonization on Indigenous landscapes and communities. Following his advice, I use stories of milpa to experience placeness and provide a representation of the transformation of modernist education systems through the resurgence of Indigenous knowledge systems. I begin this paper with a piece of the Mexica creation story to center “the consciousness of landscape” (p. 453) and continue to explain how from a modern perspective, place has shifted to produce bordered monocultures that eradicate diversity. I conclude by narrating the story of three sisters to envision the embodiment of milpa inside learning environments to form polycultures of reciprocity where animate and inanimate beings are all connected inside a web of relations belonging to the land.
“The Scream”: Using the Visual Critical Pedagogy of Subversive Indigenous Art in the Elementary Classroom to Discomfort the Comforted and Activate the Empathic, Ethical, and Relational Dimensions of Reconciliation
Authors: Brar Victor
Published: January 2024

This paper uncovers my journey as K-12 practitioner in British Columbia towards exploring the use of “subversive art” as a “visual critical pedagogy” (Gil-Glazier,2015; Naidus,2005; Peters, 2016; Zorilla & Tisdell, 2016) to advance my students and myself towards reconciliation with Indigenous Peoples in Canada.  I use the powerfully unsettling painting done by Cree artist, Kent Monkman, titled “The Scream”, as a springboard for this inquiry.  “The Scream” provides an Indigenous counternarrative to the colonial versions of residential school histories and has the potential to progress practitioners and students towards actionable reconciliation by activating their empathic and ethical consciousness.  I attempt in this essay to weave together a cluster of concepts, as I explore: (a) the nature and evolution of truth in BC’s elementary school curriculum (Andersen, 2017); (b) the historical establishment of the curriculum in a positivist modality (Gadamer, 2013; Greene, 1975; Marker 2004); (c) Greene’s (1995) argument that aesthetic education can help students and practitioners to engage meaningfully with difficult knowledge; (d) Greene’s (1977, 1995) philosophy of wide-awakeness, through which students and practitioners can activate the power of difficult knowledge; (e) Gadamer’s (2013) “fusion of horizons” as a means by which wide-awakeness can function in this context; (f) “subversive art” as a form of “visual critical pedagogy” (Gil-Glazer, 2015); (g) and the critical pedagogy of Paulo Freire. I braid these concepts together using the scholarship of Indigenous scholar, Michael Marker (1951-2021) to provide the pedagogical rationale for my determination to establish the visual critical pedagogy of “subversive art” in my classroom.

O tema deste Dossiê enseja uma multiplicidade de abordagens. No entanto, recebidas as propostas, avaliados os textos, sempre no sistema duplo cego, e aprovado um conjunto de quinze artigos, é interessante notar a presença de uma tendência dominante no tratamento dos estudos atuais sobre história da educação matemática. Eles concentram atenção nos saberes envolvidos no ensino de matemática e na formação de professores. Por certo, estudos da área, que têm a matemática como foco, não são novidade; trata-se, ao contrário, de algo óbvio. No entanto, de poucos anos a esta data, o tratamento da matemática ligada às lides escolares vem sofrendo uma modificação fundamental, de âmbito epistemológico. Não mais se considera a matemática transmitida pela escola vinda do campo disciplinar matemático, nem sendo a escola lugar de passividade, divulgando o que lhe é externo, os saberes que são elaborados fora dela. As pesquisas relativas à história da educação matemática vêm mostrando que há uma matemática própria a cada tempo escolar ligada ao ensino e à formação de professores, reafirmando o papel criativo do meio escolar.
Effect of Automated Writing Evaluation in Higher Education Academic Writing Performance
Authors: Gavina Mark Anthony , M. Ibay-Pamo Leilani
Published: January 2024

This study aimed to identify the effects of Automated Writing Evaluation (AWE) in the academic writing of thirty-seven (n=37) higher education students as it is believed to address common errors encountered by higher education students in academic writing, specifically in grammar (S-V-A and verb tense). The study used a one-group pretest-posttest design that determined the specific effect of the formulated AWE treatment on the participants. The statistical evidence showed that the AWE tool (Grammarly) feedback provision, when paired with the teacher’s role as facilitator, significantly improved students’ academic writing in terms of S-V-A and verb tense. The findings also imply that the AWE, if integrated within the instruction using its feedback provision, can significantly improve students’ grammar usage and, consequently, their overall academic writing. These inarguable positive results of the AWE intervention used in this study create new assumptions to redefine not only the teachers’ feedback provision in students’ academic writing but also teaching writing in general.
Preferred Learning styles among Junior High School students Using non Cognitive Diagnostic Assessment
Authors: Rahmatika Tia , Azmar  , Fajriawan Ifan Munif
Published: January 2024

Every student possesses individual learning styles, making it crucial to examine their preferred approaches as a means of designing courses and implementing effective instructional methods. The aim of this research endeavor was to identify the predominant learning style among junior high school students, along with discerning any gender-related associations with specific learning styles. Employing a descriptive quantitative research methodology, data were collected from 97 participants via non-cognitive diagnostic assessments. The results revealed that the visual learning style emerged as the most favored choice, with a prevalence rate of 60.8%. It was followed by the auditory style (12.4%), kinesthetic style (9.3%), visual-auditory style (7.2%), visual-kinesthetic style (7.2%), and auditory-kinesthetic style (3.1%). In terms of gender distribution, a significant majority of male students exhibited a preference for the visual style (42.3%), while the visual style also predominated among female students (18.6%). These findings hold valuable implications for fostering pedagogical excellence. Based on these results, educators are strongly advised to embrace diverse teaching methods and design multifaceted activities that encompass and accommodate the different learning styles exhibited among students.
Management of sleep problems in people with autism: an updated review
Authors: Bellato Alessio , Parlatini Valeria , Cortese Samuele
Published: January 2024

Sleep problems are more common in people with autism spectrum disorder (ASD) as compared to the general population, and may contribute to worsening social functioning, emotional symptoms, and lower quality of life. To support healthcare professionals and researchers in the field, we provide an updated overview of sleep problems in the context of autism across the lifespan and their evidence-based management, as derived from evidence-synthesis studies and the most recent randomized controlled trials. Most studies to date have been conducted in children and adolescents with autism. Several studies suggest that behavioral interventions aiming at improving sleep hygiene and environment may be beneficial, especially when actively involving parents. Furthermore, there is an increasing body of literature showing that melatonin is an effective pharmacological option for improving sleep quality in children and adolescents with autism, in line with reports showing a reduced endogenous synthesis of this hormone. Unfortunately, studies in adults are more limited, and thus, the evidence base around non-pharmacological and pharmacological interventions remains mixed. Finally, there is a growing interest towards the use of complementary interventions or food supplements, but further studies are needed to test their effectiveness. In sum, most studies to date support the use of behavioral interventions and melatonin, especially in children and adolescents with autism. However, findings need to be validated in large-scale, rigorous and blinded trials and extended to the adult population. Non-pharmacological interventions remain the first treatment option and should adopt an individualized approach, considering individual characteristics and needs, including comorbidities, family dynamics, and sleep environment.
Techno-economic and Life Cycle Analysis of the Modern Upstream Sustainable Lithium Supply Chain
Authors: Jones Jnr Erick C. , Biney Jeshurun , Jones Erick C.
Published: January 2024

Lithium is a vital resource needed for the electric vehicle (EV) transition. However, most of the mining and subsequent processing is centralized in a few countries. The United States will need to secure lithium resources to expand its EV production capacity. Additionally, in developed countries, it will not suffice just to supply lithium, but to ensure that its production is conducted under fair labor standards and environmental regulations while being at an economically viable price. In the United States, only one player has emerged that can mine and refine a substantial amount of lithium: Lithium Americas. They have tested and refined their process so that it minimizes waste and energy consumption, does not negatively impact the locale, and is economical to boot.

The adoption of strategies aimed at a more efficient use of nitrogen (N) and ontaining hig yields are important to satisfy the demand for food for animals and humans. The Tifton 85 Bermuda grass (Cynodon spp.) is a crop with high productive potential and may be used to create hay, but its culture requires elevated doses of nitrogen. In this sense, the objective of this experiment was to evaluate, in field conditions, the growth and production of Tifton 85 Bermuda grass according to nitrogen doses with urea containing urease and nitrification inhibitors for two agricultural years — eight cycles of forage growth. The treatments were evaluated in a randomized complete block design with three repetitions in a 3x5 factorial scheme. Treatments were: I) urea; II) urea + triamide N-(n-Butyl) thophosphoric (NBPT) urease inhibitor; and III) urea + nitrification inhibitor 3,4-Dimethylpyrazole phosphate (DMPP) with N rates (0, 40, 80, 120 and 160 kg ha-1 of N) applied after each growth period. Then, the study proceeded to estimate forage dry mass and N concentrations in dry mass for each of the growth cycles and their sum, as well as the apparent N recovery. N critical levels were set when relative production reached 90%. The use of urease (NBPT) or nitrification (DMPP) inhibitors did not improve the efficiency of urea regarding growth and production of Tifton 85 Bermuda grass. The appropriate dose of nitrogen for Tifton 85 Bermuda grass in a hay production system is 40 kg per ton of dry mass produced in each growth period.

The present work aimed to evaluate the production of sulfide through the application of different hydraulic retention times (HRT) and different sulfate loading rates in an up-flow anaerobic sludge blanket (UASB) reactor utilizing acetate-butyrate as electron donors and the coupling of the reactor to a crystallizer to remove metals. The sulfidogenic sludge for the UASB was generated from hydrothermal vent sediments and this was operated at room temperature (18-22 ºC). The sulfate reduction process was linked to the precipitation of Cu2+, Zn2+ and Al3+ in a crystallizer coupled to the UASB reactor (two-stage system) to avoid the toxicity of the metals to the sludge. The concentration of dissolved sulfide increased with the HRT up to 312.9 mg HS–/L at 3 d of HRT. As the sulfate loading rate was increasing, the maximum sulfide concentration obtained was of 376.8 mg HS–/L at 500 mg SO4–2/L/d (1500 mg/L), whereas the concentration of Cu2+, Zn2+ and Al3+ was up to 150, 100, and 100 mg/L, respectively. The removal efficiencies of Cu2+, Zn2+, and Al3+ were higher than 98% when they were fed separately. When a mixture of metals was added, the removal efficiency was close to 80%. Recovery of metals was lower than 57% in all cases. The sulfide production was supported with acetate-butyrate, being the former commonly accumulated because of the oxidation of higher organic compounds; in this case, its utilization sustained sulfate reduction. This process could be controlled by parameters such as HRT and sulfate loading rate to improve the performance of the bioreactor in the treatment of the effluents contaminated with metals in a two-stage system.
The balance In the six dimensions of space-time description of quantum mechanics phenomena and nature of time
Authors: Mousavi Seyed Kazem
Published: January 2024

This study presents a theory with a six-dimensional space-time structure, R^6, in order to describe quantum mechanic phenomena, the time arrow and quantum gravity. The interpretation of quantum world phenomena using four-dimensional space-time would be a very complicated and indescribable task. The dual wave-particle behavior, entanglement, quantum corridors, etc., represent the complex space-time structure. Previous studies indicate that complicated behaviors of particles in quantum mechanics are basically considered as the inherent behavior of those particles. The theoretical framework of the balance is the transformation of imaginary dimensions into geometric dimensions and the description of quantum mechanical phenomena using external Euclidean geometry. The six-dimensional space-time structure consists of three space and three time dimensions and the time arrow is the result of the impossibility of the existence of matter in six space-time dimensions, and the direction of the arrow is aligned with the expansion of the universe.

Published: January 2024

We developed multiple equations to observe the two and three flavors of neutrino oscillation with the mixing angle based on L/E=0.1 to 0.9 in this study. In different settings, the nature of the neutrino oscillation probability was discovered to be varied in different equations. The observation indicates increasing likelihood in one equation and decreasing probability in the other equations in two flavor oscillation neutrinos. To characterize the probability of neutrino oscillation, we use four distinct angles: 5degree, 10 degree, 15degree , and 20degree . The probability of neutrino oscillation was determined to be highest at an angle of 15 degrees. However, with increasing mixing angles, the likelihood of oscillation increases on the basis of created equation (25) and decreases on the basis of equations (26) and (27) in the three-flavor neutrino oscillation. From generated equations (25) and (26) the maximum neutrino oscillation of probability is discovered at an angle of 15degree , however, from equation (27), the maximum probability is observed at 5degree . The greatest neutrino oscillation is found to be 0.9999 and the minimum is zero in all of these two and three flavors of oscillation.

Sea Breeze Front (SBF) is one of the important components of sea breeze circulation, which plays role in coastal area’s atmospheric dynamics. SBF causes significant changes in temperature and humidity profiles and initiates updrafts that induce convective activity. This study aims to determine the characteristics of SBF and its impact on convection activity using Doppler weather radar on the west coast area of South Sulawesi during dry season. SBF identification utilized PPI and CMAX products to detect convective clouds and SRI to estimate rainfall intensity, then verified it using Automatic Weather Station (AWS) and Automatic Rain Gauge (ARG). SBF was generally detected at 10.30–14.30 LT with an average moving speed of 2.04 m/s. The length of SBF ranges from 15.47–21.08 km and moves inland as far as 12.57–26.09 km with 0.51–0.89 km of column depth. There was a difference in the average value of solar radiation intensity up to 106 W/m2 and 0.5°C of temperature during SBF Days. SBF caused 17 events of convective activity with a maximum reflectivity value of 42–60 dBz and 4–8 km of cloud diameter. Five out of 17 convective activities indicated the occurrence of light rain on the surface.

This study was carried out to investigate the effects of refuse dumpsites on the quality of groundwater in some major towns in Niger State, Nigeria. A total of sixty (60) Vertical Electrical Soundings (VES) was conducted across fifteen (15) dumpsites within the study areas; twenty (20) VES at each of the three (3) dumpsites of Lapai, Bida and Paiko using Schlumberger configuration to investigate the possibility of contamination of groundwater in the areas. The resistivity data were collected using G41 Resistivity Meter and interpreted using IPI2Win Software. The results revealed four geo-electrical layers. The resistivity values of the Aquifer layers of Lapai dumpsites ranged from 136 Ωm to 681 Ωm, with the thickness ranging between 2.82 - 8.77 m at the depth of 4.21 – 10.90 m at Engr. A. A. Kure dumpsite. At Malle dumpsite, the thickness range was (1.10 – 4.39) m and the depth at 5.27 – 12.70 m. The resistivity values of the aquifer layers at Bida dumpsites ranged from 161.10 Ωm to 223 Ωm, with the thickness ranging between 4.86 and 11.00 m at the depths of 7.65 – 12.70 m while at Mayaki Ndajiya dumpsite, the thickness range was 4.91 – 23.46 m at the depth of 6.84 – 25.57 m. Also the resistivity values of the aquifer layers of Paiko dumpsites ranged from 20.90 Ωm to 110 Ωm with thicknesses ranging from 2.33 to 14.00 m at the depth range of between 3.85 and 15.50 m at Gidan Marafa dumpsite while the thickness range was from 3.19 – 9.04 m at the depth of 6.70 – 14.14 m at Angwan Akimi dumpsite. These values were used to compute the Dar Zarrouk parameters which indicate aquifer protectivity. The protective capacity of the over burden rock materials at Lapai dumpsites ranged from 0.010 – 0.076 Siemens, while at Bida dumpsites it ranged 0.009 – 0.152 Siemens and at Paiko dumpsites it ranged between 0.025 – 0.046 Siemens. The low protective features observed in the Aquifer zones of Lapai, Bida and Paiko dumpsites indicated the possibility of leachate migration from the waste dumpsites infiltrating into the aquifers and polluting the groundwater. It is evident, from the results of this geophysical survey that the water in the study areas of Lapai, Bida and Paiko could be polluted leading to water related diseases.

Published: January 2024

The inversion of the Rayleigh wave dispersion curve is a crucial step in the multi-channel analysis of surface waves (MASW) method, used to obtain the shear wave velocity (Vs) profile. The nonlinear and multimodal nature of the dispersion curve makes a global optimization approach, such as particle swarm optimization (PSO) and genetic algorithm (GA), the optimal choice for inversion. This study aims to compare the performance of multiple inversions of PSO (MI-PSO) and multiple inversions of GA (MI-GA) in solving the inversion problem of the Rayleigh wave dispersion curve. The test results indicate that the utilized MI-PSO outperforms MI-GA in terms of computational time and accuracy of the obtained model

Every year, the number of potentially life-threatening pathogenic biological agents (PBAs) is rapidly growing, which are represented by viruses, bacteria, rickettsia, chlamydia, protozoa, fungi, genetically engineered constructs and modified microorganisms, prions and toxins. The use of PBAs for the purpose of destroying society, the economic resources of the country, deteriorating the quality of food and water supplies, intimidating the population, provoking internal unrest, destabilizing government, and creating economic, socio-psychological and environmental crises is nothing more than biological terrorism. The numerous international agreements, treaties and protocols that have been developed and ratified to date, limiting the production and use of weapons of mass destruction, do not guarantee the elimination of the risks of illegal acquisition and use of biologically active substances by terrorist organizations, which does not exclude the possibility of committing acts of bioterrorism. In this regard, the preservation and strengthening of administrative-legal, medical-biological, sanitary-epidemiological, veterinary and phytosanitary and other measures should form the basis of the state policy of the Russian Federation to counter the use and spread of PBAs.
