Abstract. The Fennoscandian boreal and mountain regions harbour a wide range of vegetation types, from boreal forest to high alpine tundra and barren soils. The area is facing a rise in air temperature above the global average and changes in temperature and precipitation patterns. This is expected to alter the Fennoscandian vegetation com-position and change the conditions for areal land-use such as forestry, tourism and reindeer husbandry. In this study we used a unique high-resolution (3 km) climate scenario with considerable warming resulting from strongly increasing carbon dioxide emissions to investigate how climate change can alter the vegetation composition, biodiversity and availability of suitable reindeer forage. Using a dynamical vegetation model, including a new implementation of potential reindeer grazing, resulted in simulated vegetation maps of unprecedented high resolution for such a long time period and spatial extent. The results were evaluated at the local scale using vegetation inventories and for the whole area against satellite-based vegetation maps. A deeper analysis of vegetation shifts related to statistics of threatened species was performed in six “hotspot” areas containing records of rare and threatened species. The simulations show dramatic shifts in the vegetation composition, accelerating at the end of the century. Alarmingly, the results suggest the southern mountain alpine region in Sweden will be completely covered by forests at the end of the 21st century, making preservation of many rare and threatened species impossible. In the northern alpine regions, most vegetation types will persist but shift to higher elevations with reduced areal extent, endangering vulnerable species. Simulated potential for reindeer grazing indicates latitudinal differences, where the current higher potentials in the south will diminish, while future potentials will increase in the north, especially for the summer grazing grounds. These combined results suggest significant shifts in vegetation composition over the present century for this scenario, with large implications for nature conservation, reindeer husbandry and forestry.
Short Communication: Cosmogenic noble gas depletion in soils by wildfire heating
Authors: Balco Greg , Hidy Alan , Struble William T. , Roering Joshua J.
Published: September 2023

Abstract. Measurements of cosmic-ray-produced beryllium-10, neon-21, and helium-3 in quartz in a soil proﬁle from a forested landscape in the Oregon Coast Ranges show that the cosmogenic noble gases 21Ne and 3He are depleted relative to 10Be in the shallow subsurface. As the noble gases are mobile in mineral grains by thermally activated diffusion and 10Be is not, this is most likely the result of surface heating by wildﬁres and subsequent mixing of partially degassed quartz downward into the soil. Cosmogenic noble gas depletion by wildﬁre heating of soils is a potential means of estimating wildﬁre intensity and/or frequency over pre-observational time scales.
Natural fracture patterns at Swift Reservoir anticline, NW Montana: the influence of structural position and lithology from multiple observation scales
Authors: Cawood Adam J. , Watkins Hannah , Bond Clare E. , Warren Marian J. , Cooper Mark A.
Published: September 2023

Abstract. Subsurface datasets typically lack the resolution or coverage to adequately sample fracture networks in 3D, and fracture properties are typically extrapolated from available data (e.g. seismic data or wellbore image logs). Here we assess the applicability of extrapolating fracture properties (orientation, length, and intensity) across observation scales in deformed, mechanically layered carbonate rocks. Data derived from high-resolution field images, medium-resolution digital outcrop data, and
relatively low-resolution satellite imagery at Swift Reservoir anticline, NW Montana are leveraged to (i) assess interacting structural and stratigraphic controls on fracture development, and (ii) compare estimated fracture properties derived from multiple observation scales. We show that
hinge-parallel and hinge-perpendicular fractures (i) make up the majority of fractures at the site; (ii) are consistently oriented with respect to the fold hinge, despite along-strike variability in the fold hinge orientation; and (iii) exhibit systematic increases in intensity towards the anticline hinge. These fractures are interpreted as having formed during folding. Other fractures recorded at the site exhibit inconsistent orientations, show no systematic trends in fracture intensity, and are interpreted as being unrelated to fold formation. Fracture orientation data exhibit the greatest agreement across observation scales at hinge and forelimb positions, where hinge-parallel and hinge-perpendicular fracture sets are well developed, and little agreement on the anticline backlimb, where fracture orientations are less predictable and more dispersed. This indicates that the scaling of fracture properties at Swift Reservoir anticline is spatially variable and partly dependent on structural position. Our results suggest that accurate prediction and extrapolation of natural fracture properties in contractional settings requires the assessment of structural position, lithologic variability, and spatially variable fracture scaling relationships, as well as consideration of the deformation history before and after folding.
Snow depth in high-resolution regional climate model simulations over southern Germany – suitable for extremes and impact-related research?
Authors: Poschlod Benjamin , Daloz Anne Sophie
Published: September 2023

Abstract. Snow dynamics play a critical role in the climate system as they affect the water cycle, ecosystems and society. Within climate modelling, the representation of the amount and extent of snow on the land surface is crucial for simulating the mass and energy balance of the climate system. Here, we evaluate simulations of daily snow depths against 83 station observations in southern Germany over the time period 1987 – 2018. Two simulations stem from high-resolution regional climate models, the Weather Research & Forecasting Model (WRF) at 1.5 km resolution and the COSMO-CLM (CCLM) at 3 km resolution. Additionally, the hydrometeorological snow model AMUNDSEN is run at the point scale of the climate stations based on the atmospheric output of CCLM. The ERA5-Land dataset (9 km) complements the comparison as state-of-the-art reanalysis land surface product. All four simulations are driven by the same atmospheric boundary conditions of ERA5. The WRF simulation features a cold bias of -1.2 °C and slightly overestimates snow depth (+0.4 cm) with a root-mean-square error (RMSE) of 4.3 cm. Snow cover duration slightly exceeds the observations (+6.8 d; RMSE = 20.5 d). The CCLM reproduces the winter climate very well, but shows a strong negative bias at snow depth (-2.5 cm; RMSE = 5.6 cm) and snow cover duration (-20.0 d; RMSE = 27.1 d). AMUNDSEN improves the reproduction of snow cover duration (+6.5 d; RMSE = 16.6 cm) and snow depth (+2.2 cm; RMSE = 6.2 cm). ERA5-Land shows a strong positive bias in mean winter snow depth (+3.6 cm; RMSE = 14.5 cm) and snow cover duration (+33.9 d; RMSE = 44.0 d). All models fail to skilfully predict white Christmas. For extreme events of snow dynamics such as annual maximum snow depths, maximum daily snow accumulation and melting, the ERA5L and CCLM show large biases in amplitude and deviations in seasonality. WRF and AMUNDSEN can improve the representation of extremes but still with considerable limitations. The high spatial resolution of convection-permitting climate models shows potential in reproducing the winter climate in southern Germany. However, the uncertainties within the snow modelling prevent a further straightforward use for impact research. Hence, careful evaluation is needed before any impact-related interpretation of the simulations, also in the context of climate change research.
Towards smart blades for vertical axis wind turbines: different airfoil shapes and tip speed ratios
Authors: Tirandaz Mohammad Rasoul , Rezaeiha Abdolrahim , Micallef Daniel
Published: September 2023

Abstract. Future wind turbines will benefit from state-of-the-art technologies that allow them to not only operate efficiently in any environmental condition but also maximise the power output and cut the cost of energy production. Smart technology, based on morphing blades, is one of the promising tools that could make this possible. The present study serves as a first step towards designing morphing blades as functions of azimuthal angle and tip speed ratio for vertical axis wind turbines. The focus of this work is on individual and combined quasi-static analysis of three airfoil shape-defining parameters, namely the maximum thickness t/c and its chordwise position xt/c as well as the leading-edge radius index I. A total of 126 airfoils are generated for a single-blade H-type Darrieus turbine with a fixed blade and spoke connection point at c/2. The analysis is based on 630 high-fidelity transient 2D computational fluid dynamics (CFD) simulations previously validated with experiments. The results show that with increasing tip speed ratio the optimal maximum thickness decreases from 24 %c (percent of the airfoil chord length in metres) to 10 %c, its chordwise position shifts from 35 %c to 22.5 %c, while the corresponding leading-edge radius index remains at 4.5. The results show an average relative improvement of 0.46 and an average increase of nearly 0.06 in CP for all the values of tip speed ratio.
The Nightmare by Henry Füssli: a review of its association with sleep paralysis through the idea of the sublime
Authors: Salazar Amaia , Raquejo Tonia
Published: September 2023

In this article, we closely examine the pre-Romantic artist Henry Füssli's version of The Nightmare (1781), observing how he not only accurately depicted the described and identified characteristics of the sleep disorder known as sleep paralysis, but also personified the affected sleeper's own sensations through his work. We undertake a comprehensive review of his work in order to explore the motivations behind Füssli's interest in depicting parasomnia, and attempt to understand the pictorial corporeality inspired by this phenomenon. To achieve the latter aim, we examined the different determining factors belonging to the Burkean aesthetic categories of beauty and the sublime. This approach highlights how Füssli managed to capture parasomnia in his work under a misogynistic gaze through the idea of the sublime, and the importance of its iconic and repeated representation in art. Through this, we can observe, understand, and precisely interpret the psychophysical effects of this experience on the viewer and detect the pleasure of scopophilia in Füssli's male gaze.

Published: September 2023

The optical properties of a cadmium selenide (CdSe) film doped with aluminum (Al) at a rate of (3%) have been studied. It was deposited on glass substrates at 250 K with a thickness of 0.15 µm and a deposition rate of 2± 0.1 m.sec-1 using a thermal evaporation technique to create the compound. The optical characteristics of the produced film were investigated after being subjected to irradiation by 50 mW, 1064 nm IR laser for 15 minutes at a distance of 0.5 m. Through monitoring the absorbance and transmission spectra of prepared thin film across the wavelength range (190-1100 nm), the optical energy gap value for the permitted direct electronic transitions was determined, and the absorption and reflectivity coefficients were computed and investigated. The optical experiments included computing the optical constants, and result explained that the optical energy gap decreased from (1.76 eV) to (1.64 eV) following irradiation (extinction coefficient, refractive index, and absorption coefficient).

Published: September 2023

t. The article presents General theoretical concepts of the liquid state from the point of view of statistical thermodynamics, as well as computer modeling of the dynamic properties of the liquid state. It is shown that in melts, due to the high mobility of its particles and the absence of a long-range order (as in a crystal lattice), the nearest surroundings of different atoms or molecules can differ quite significantly both in the number of neighbors and in their spatial location. In this regard, the correlation function was calculated using the molecular dynamics method and the radial distribution function. A machine experiment for modeling the structure of melts, as well as for constructing the geometry of cluster structures, is characterized. Specific algorithms for their implementation are considered. Cyclic BornKarman boundary conditions are introduced, the base cell is surrounded by its own replicas, and each such replica exactly repeats the microstates of the base lattice. A General algorithm for constructing Voronoi polyhedra using computer programs is given
Prevalence of Trismus in Post Operative Oral Cavity Cancer Patients in Rural Area - A Cross Sectional Study
Authors: Hogade Swaranjali , Borkar Pradeep
Published: September 2023

Oral cancer constitutes over 90% of malignancies affecting the oral and maxillofacial region. This is likely due to prolonged use of cigarettes and alcohol. Trismus is a significant complication of oral malignancies or its treatment. It hampers, eating, maintaining oral hygiene, and other social interactions to varying degrees. Trismus is recognized at a late stage due to the lack of understanding regarding early diagnosis, prevention, and treatment thus correct physical therapy is rarely delivered. The presence of physiotherapy intervention would be detrimental to aid in ability of the patient to cope with the effects of the disease or its treatment on their functional capacity and quality of life. Hence the study aimed to identify the prevalence of trismus in oral cancer patients in rural areas post-operatively. To identify whether trismus is prevalent in the post operative oral cavity patients in rural area. Study began after the clearance from the institutional ethical committee and then the patients were selected from the Oncology department of Pravara Rural Hospital. Informed consent was taken prior to the study and 60 patients were included in the study. The maximum mouth opening i.e., the distance between the two incisors was taken using the Metal ruler to identify the presence of trismus. Out of 60 oral cancer patients, 37 patients had difficulty in mouth opening which accounts for 67% prevalence of Trismus. Trismus is a major complication of oral malignancies or its surgical and radiotherapy management. Early diagnosis of trismus must be taken into account in order to provide prompt intervention and the development of preventive strategies. This study concludes that the prevalence of trismus is 62% in oral cancer patients and the prevalence was highest in maxilla and mandible (67%) followed by buccal mucosa (65%), tongue (45%) and hard palate (40%).

A Review of the Role of Canakinumab - An Anti-Inflammatory Agent in CAD
Authors: Olayinka Temitope , Okoye Chiugo , Amarachi Oham
Published: September 2023

Coronary Artery Disease (CAD) is the leading cause of mortality and loss of disability-adjusted life years (DALYs) worldwide. Optimal medical therapy is the cornerstone of management for patients with CAD. However, patients on currently available medical therapy still have a residual risk of poor cardiovascular outcomes. Recent studies have underscored the role of inflammation in the development and progression of CAD and proposed that anti-inflammatories such as Canakinumab may significantly reduce the incidence of poor cardiovascular outcomes. This review explored the role of Canakinumab in CAD management and discovered that Canakinumab without the requirement of daily dosing, reduces the incidence of adverse cardiovascular outcomes in CAD patients. However, its high cost and limited knowledge concerning its long-term effects may limit its use for CAD patients

Frequency of Os trigonum and Stieda process, determination of its relation with posterior ankle pain and tendinopathy by ankle MRI
Authors: POÇAN Süheyl , KARAKAŞ Levent
Published: September 2023

ABSTRACT

Aim: To investigate the frequency of Os trigonum and Stieda process and the relationship of Os trigonum with other pathologies detected by magnetic resonance imaging (MRI) in patients with posterior ankle pain.

Methods: This was a retrospective study conducted by re-examining MRI images obtained between January 2017 and May 2023. The study included 482 patients (496 ankles) who underwent ankle MRI for diagnostic purposes due to posterior or posterolateral ankle pain. MRI images were re-examined for the following parameters: fractures, contusion, tendinosis, ligament injury, arthritis, effusion, presence of Stieda process, posterior ankle bursa impingement, Os trigonum, retrocalcaneal bursitis, ganglion cyst, widespread osteophytes, accessory navicular bone, presence and grade of osteochondritis dissecans, and presence and type of Achilles tendon pathology.

Results: The mean age of the participants was 41.96 ± 15.89 (7–83 years), and 51.04% (n = 246) were male. Os trigonum was detected in 17 patients (3.43 %), and none of the cases were bilateral. The likelihood of Os trigonum was significantly higher in males (p = 0.016, OR: 4.725, 95% CI: 1.341 - 16.655). Stieda process was detected in 186 patients (37.5 %). The accessory navicular bone was detected in 8 (1.61%). The percentage of patients with pathological metatarsal fractures was significantly higher in patients with Os trigonum (p = 0.034). The frequency of Stieda process was significantly lower in patients with Os trigonum (p = 0.013, OR: 0.099, 95% CI: 0.013 - 0.755). There were significantly fewer cases of talotibial effusion in the Os trigonum group (p = 0.030).

Conclusion: While Os trigonum appears to be significantly more frequent among males, it is less frequent in the presence of the Stieda process and talotibial effusion.

Published: September 2023

The posterolateral tibial plateau fracture is an uncommon intra-articular injury and mostly needed surgery. However, its surgical approach remains controversial. This manuscript describes an anterolateral approach to treat posterolateral tibial plateau fractures and evaluates the patient’s functional outcomes. From June 2018 to July 2021 seventeen patients with posterolateral tibial plateau fractures were surgically treated through an anterolateral approach. The intraoperative and postoperative follow-up indicators were recorded. The reduction quality of fractures was assessed using Rasmussen radiological score, and postsurgical functional recovery was estimated using Rasmussen clinical score and Lysholm score. The mean follow-up interval was 28.71 ± 9.61 months (range 18-44). The surgery time and blood loss were 111.06 ± 15.62 min (range 85-140) and 118.12 ± 38.45 mL (range 80-250) separately. Postoperatively, the Rasmussen radiological score was 16.24 ± 2.33 (range 12-18). The average time of bone union was 14.29 ± 1.53 weeks (range 12-18). At the final follow-up, the average PTS and MPTA were 9.71 ± 2.76° (range 5-14°) and 86.82 ± 2.04° (range 84-90°) separately. A satisfactory articular reduction was achieved in 16 patients (94.1%). The final ROM was 123.29 ± 19.70° (range 60-142°). The Rasmussen clinical score and Lysholm score were 25.71 ± 5.74 (range 10-30) and 91.47 ± 6.50 (range 75-98) separately. Anterolateral approach has minimal risk of intraoperative neurovascular injuries in the popliteal fossa with satisfactory results. The hardware removal was also facilitated. This approach is feasible, safe and efficient.

Published: September 2023

Tibial plateau fractures are complex injuries which carry significant morbidity and economic burden. They can present complex geometry depending upon the direction of the force and position of the limb and are often associated with significant soft-tissue injury. While the goals of adequate reduction, stable fixation, and early mobilization remain unchanged, the management of these injuries can be challenging even to experienced orthopaedic surgeons. Lacking consensus, this review aims to provide a summary of current state of orthopaedic practice in the face of tibial plateau fractures. A PubMed search for relevant recent articles as well as a reading of classical articles on tibial plateau fractures was carried out. The focus remained on articles concerned with management modalities and recent advances. A review of some classification systems was also done and included. A great majority of these fractures need operative fixation while respecting the soft tissues. Numerous methods have been reported in the literature including but not limited to plates, screws, external fixators, arthroscopy assisted methods, balloon-cement tibioplasty, or a combination thereof. There is a shortage of randomized controlled trials comparing various operative methods. This article provides a review of various techniques and latest advances made in the management of tibial plateau fractures. The key to achieving optimal functional outcome is using a tailored approach to the individual patient accounting for factors related to the injury pattern, type of host, surgical skills and experience, and local availability of implant devices while taking care of soft tissue. While there is no gold standard, a staged procedure is recommended with early spanning and definitive fixation at later stage by any appropriate methods while respecting the soft tissue, achieving anatomical reduction and adequate fixation and, early rehabilitation.
Isolated femoral avulsion of the popliteus tendon: a systematic review of the literature
Authors: HEYLEN Steven , DEMEY Patrick , MOUSATI Zakaria
Published: September 2023

The popliteus tendon is an important part of the posterolateral corner of the knee. Isolated injuries to the posterolateral corner are very rare, as most injuries occur in multiligamentous knee trauma. Purely isolated popliteus tendon injuries are even more rare. There is very little evidence for treatment of isolated popliteus tendon avulsion injuries. The aim of this systematic review is to report on all publications regarding isolated popliteus tendon avulsion injuries and hopefully provide some guidance for future treatment algorithms. A systematic review of the literature was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Studies were included if they documented isolated popliteus tendon avulsion injuries. Exclusion criteria were studies with popliteus injuries in combination with other knee ligamentous injuries and popliteus tendon injuries other than femoral avulsion injuries. Twenty-eight studies were included which mentioned in total 38 patients with isolated popliteus tendon avulsion injuries. 24 patients (63%) were treated operatively. 3 (8%) patients were diagnosed arthroscopically but did not receive any surgical treatment. 9 patients (24%) were treated conservatively. In two publications, there was no mention of treatment. We found no clear recommendations in the literature for treatment of this rare injury.

In the background of the ongoing pandemic HIV/AIDS, the people were affected with the newly emerging Corona virus SARS-CoV-2, that rapidly turned into pandemic dimensions. There are data that, in various aspects, HIV infection was similar to SARS-CoV-2. The purpose of this review was to search for similarities and differences between both pandemics in view to use the experience of the past and knowledge we have acquired in order to better overcome current and future pandemics. Material/Methods: The iterature used is based on databases PubMed, Embase and random search on the Internet with the keywords COVID-19 and HIV, as well the Boolean operator "AND" to achieve a search of "COVID-19 and HIV". Review Results: In the present review summary, we provide data for similarities and differences regarding virological, immunologic, clinical and pharmacological aspects of HIV and SARS-CoV-2 infections and associated with them pandemics. Conclusion: SARS-CoV-2 was here and will remain here. COVID-19 is not the last pandemic, and people should be prepared for new encounters with agents of high virulence and pandemic potential.
Modelling ternary electrolyte systems for Na-ion batteries
Authors: Brandell Daniel , Costa Luciano T.
Published: September 2023

To realize high-performing Na-ion batteries, specific electrolyte systems needs to be developed that are tailored for this specific battery chemistry and its electrode materials. This has shown challenging, and especially the interphase layer formation and stability appears different in Na-ion batteries than for Li-ion battery counterparts. In this context, it is of interest to both develop alternative electrolyte systems, and to understand the fundamental chemical processes better. This presentation will focus on both these aspects, where ternary electrolyte systems (comprising Na-salt, ionic liquids and conductive polymers) are been investigated using Molecular Dynamics (MD) simulation techniques. MD has shown to be a powerful tool to explore the atomic-scale structure-dynamic properties of electrolytes. In particular, we will discuss our latest findings on NaTSFI- and NaFSI-based electrolytes comprising poly(ethylene oxide) (PEO) and ionic liquids of N-methyl-N-propylpyrrolidinium (Pyr13) and the respective anions for different concentrations and temperatures. These MD simulations unveil an interplay between the coordination chemistry and the dynamic properties in these ternary electrolytes, and how the coordination strength controls the conductive properties.

Published: September 2023

Los avances que debe realizar la justicia salvadoreña son retadores, ya que no solo significan el salvaguardar los principios constitucionales, sino que, además, estos retos son de carácter tecnológico. La misma sociedad de la información va reclamando de manera apremiante el implementar las nuevas tecnologías en todas nuestras actividades diarias, y la justicia no puede atrasarse más en este avance tecnológico. Existen líneas claramente identificables sobre el progreso que la Corte Suprema de Justicia de El Salvador ha considerado sobre la modernización o digitalización de sus sistemas. Pero tal impulso de progresión no puede quedarse únicamente como una respuesta a la forma de solucionar la problemática de trabajo por el COVID-19, sino que debe dirigirse a modernizar su sistema de justicia, actualizando la atribución de una "pronta y cumplida justicia", como lo manda la Constitución.

Este artigo investiga a dinâmica da economia brasileira de 2000 a 2016, baseando-se na taxa e lucro e seus determinantes (tecnologia, distribuição e demanda) e estabelecendo uma conexão com a financeirização da economia. Entre 2003 e 2010, a economia brasileira experienciou crescimento econômico com distribuição de renda favorável aos salários. A taxa de lucro caiu a partir de 2011, culminando na crise econômica de 2014. A pesquisa aqui apresentada encontra uma cooperação entre capitalistas e trabalhadores durante os governos Lula e competição durante os governos Dilma. Nós calculamos a taxa de lucro sob patrimônio líquido, corroborando o resultado de funcionalidade entre o lado financeiro e o lado produtivo de 2003 a 2010, e disfuncionalidade das finanças para fins de acumulação a partir de 2011, quando a lucratividade caiu junto a um aumento da alavancagem.

Notas introdutórias sobre a teoria das relações de produção de Marx
Authors: Germer Claus
Published: September 2023

As relações de produção constituem um elemento central da estrutura da sociedade em todos os modos de produção, e, consequentemente, da teoria do capitalismo de Marx, exposta no O capital. No entanto, surpreendentemente, este conceito continua sendo mal compreendido. O objetivo do presente artigo é contribuir para o esclarecimento do seu significado, tal como elaborado por Marx, por um lado com base nos princípios metodológicos inspirados no materialismo e na dialética e, por outro, por intermédio da exploração dos principais escritos, seus e de Engels, desde as obras fundadoras do materialismo histórico.

Towards an Enabling Legal and Regulatory Framework for International Franchising Business in Nigeria
Authors: Bello Fatima
Published: September 2023

UNCTAD has estimated that around 18 – 21 million people are employed under Non – Equity Modes (NEMs) of production, with the bulk of them being in contract manufacturing, outsourcing, and franchising. 80% of these employments are mostly in developing countries. If well-strategised, NEMs can present massive potential for developing countries such as Nigeria to increase their share of value addition, build productive capacity, integrate the country into the Global Value Chain (GVC), and increase its participation in international trade. Nigeria has signed and ratified the African Continental Free Trade Area (AfCFTA) Agreement, is a member of the WTO, and has integrated Sustainable Development Goals (SDGs) into its development strategy. It seeks to develop its productive capacity through industrialisation, pursue export-led growth through trade under the AfCFTA and increase participation in the GVC. Franchising as a business model is used to mitigate against certain risks, create jobs, and is used as a tool to gain entry into a new and/ or uncertain business environment making it worth exploring to improve international franchising in Nigeria. The research observed that although attempts have been made to woe international franchisors by Nigeria, the sector performed below expectation. The paper finds that the legal and regulatory environment does not create an enabling environment for franchises to thrive, This makes the business environment unattractive for international franchising. Hence, using the doctrinal approach, this paper seeks to analyse the legal and regulatory framework for franchising business in Nigeria to determine how prepared it is to regulate franchising business in Nigeria to assess its capability to support Nigeria, and proffering suggestions on how to improve it to enable Nigeria leverage on it to undergird its industrialisation and export market development.
Proof by Electronically Generated Evidence under the Evidence Act (2011)

The underlying principle upon which the concept of weight of evidence is based is that the court is urged to confer probative value or otherwise on a document that is being tendered and received in evidence.An invitation to ascribe probative value to a document which is evidence before the court works on the assumption that the document has been admitted in evidence as an exhibit. This assumption or presumption is rebuttable as the admissibility of a document could still be a relevant factor in the course of final addresses, judgment or even on appeal.Two key factors are critical in respect of electronic evidence in judicial trials or proceedings. These are admissibility and weight of documents. However, while the Evidence Act (2011) creates a general framework regarding the weight to be attached to such electronic evidence, it does not set out any basis for the opposing party to be able to show that the produced electronic evidence falls short of any of the above factors for probability. The challenges a party seeking to show that the produced electronic evidence is not probable are enormous. Implicit in the factor for admissibility is the confidentiality of the electronic evidence. Using doctrinal approach through content analysis of Nigerian statutes, case law, and relevant literature, the paper examines the principles relating to the ascription of probative value or weight of electronic evidence as a means of proof of a particular fact in judicial proceedings. The paper finds that generally, it is difficult to detect where the product of an electronic device has been tampered with; and since the provisions of the Evidence Act, 2011 is not clear on the authentication of electronic documents, the chance that the courts are more likely to be misled by evidence produced through an electronic device is higher than a hard copy of the evidence. Accordingly, the paper recommends that the Act be amended to include detailed rules for presenting electronically generated evidence.
Supremacy of the Constitution of the Federal Republic of Nigeria 1999 (As Amended): A Myth or Reality?
Authors: Jimoh Saliu
Published: September 2023

Realistically speaking, the rate at which Nigerians, both high and low, trampled upon the provisions of the constitution in their daily doings, and with impunity for that matter leaves much to be desired. Can we, with all sense of responsibility, say that the provisions of the Constitution of the Federal Republic of Nigeria 1999 as amended are sacrosanct and most respected by all its subjects as codified?  Are these provisions cosmetic or reality? The research employed doctrinal research methodology by analysing primary and secondary sources of data and texts. The research found that this issue is very pivotal  and of jurisprudential importance to constitutional development in Nigeria and there is therefore an imperative need to make radical contribution to the subject matter through critical thinking and practical analysis of realities on ground vis- a-vis what is obtainable in an ideal constitutional democracy. It concludes that If the Supremacy of the constitution will move from being a mere farce to a real deal, the organs of government, especially the Executive and the Legislature have to respect the spirit and letter of the constitution.
Analysing the Efficacy of Customary Arbitration for Settlement of Land Disputes in Nigeria

Published: September 2023

A number of cases in court with respect to the recognition and enforcement of customary arbitration awards relate to land disputes. Customary arbitration awards and the resort to traditional oath taking seem to be one of the ways by which title to land is established, particularly under customary law. The courts in Nigeria have been very active on the resolution of land disputes even after the conduct of customary arbitration. This is probably due to the uncertainty emanating from whether a customary arbitration award can be deemed to be final, binding or enforceable where a party decides to reject the award. Relevant judicial decisions however show that the perceived confusion or uncertainty over the efficacy of customary arbitral award is lack of understanding of the peculiar facts and decision in each case. This article adopts the doctrinal research methodology by relying mainly on relevant judicial decisions and literature to analyze the efficacy of customary arbitration as a dispute resolution mechanism for settlement of land dispute in Nigeria. It finds that a customary arbitration award estops another party from reiterating the same issue in court.
Variables that Influence Customers' Choice to Purchase Term Deposits
Authors: Yang Yuanzheng
Published: September 2023

This paper focuses on how to use data mining technology to improve the success rate of bank periodical deposits subscriptions, under the premise of considering the data imbalance problem, processing customer data and making targeted subscription recommendations according to the final classification results to reduce the cost of the bank, ultimately to increase the benefit of the bank. This paper investigates the potential factors that can influence a customer's decision to subscribe to a time deposit at a bank. To do this, a decision tree algorithm was used to analyze 21 different factors that may have an impact on this decision. Through this analysis, a decision tree model of influencing factors of bank customer subscription to time deposits was constructed. This model provides useful insights into how customer behavior may be influenced by various factors, and can be used to inform decisions around marketing and product development. Research has revealed that there are three key factors which have a major impact on customers subscribing to time deposits: the employee index, the duration, and the month. By taking these three factors into account, banks can optimize the range of customers they market time deposits to, and increase their efficiency in this regard. This can lead to an increased number of subscriptions, and more successful campaigns due to the targeted approach. Additionally, banks can use this research to identify areas of improvement and focus on aspects that can further increase the success rate of their campaigns.

Published: September 2023

This paper provides an overview of the business model of Formula 1 (F1), a premier motorsport racing competition. The main sources of revenue for F1 include TV broadcasting rights, race hosting fees, sponsorship and naming rights, and merchandise sales. In analyzing F1's business model, this paper examines the various revenue streams and the challenges they face. F1 is facing challenges in the area of TV broadcasting rights due to the rise of streaming services and the changing media landscape. Additionally, scheduling conflicts due to the limited time available to hold races are creating tensions between stakeholders. The paper also looks at the impact of sponsorship on F1, including the extension of sponsorship beyond traditional marketing tactics by brands like Rolex and IWC. However, some sponsorship deals have encountered issues, such as Marlboro's association with tobacco and Alfa Romeo's partnership with Stake violating certain countries' laws. It also draws upon a combination of literature review and personal experience to identify key issues and propose potential solutions. By analyzing existing research and drawing upon observations, the paper aims to provide a comprehensive understanding of the business model of Formula 1 and the challenges and opportunities it faces in the current market. Finally, the paper concludes with recommendations for addressing these issues, including exploring alternative revenue streams, implementing more flexible scheduling, and ensuring that sponsor partnerships align with F1's values and do not violate local laws.
