Fixed-time Synergetic Control for Synchronization of Fractional-order Chaotic Systems
Authors: HAMOUDI A. , ALOUANE S. , ABERKANE S. , DJEGHALI N. , BETTAYEB M.
Published: July 2024

In this paper, a fixed-time synergetic control is proposed for the synchronization of fractional-order chaotic systems. It is similar to the sliding mode approach but without chattering and achieves exact convergence of the macro-variable. Synergetic control is a robust approach that does not require linearization and is suitable for real-time implementation since it does not require a discontinuous term in its control law. The Lyapunov framework is used to ensure the convergence of the controlled system. Computer simulations are performed to illustrate the effectiveness of the proposed method.
Investigating How International Trade Shapes Nigeria’s Economy
Authors: Tevin-Anyali Chizoba Linda
Published: July 2024

The study investigated how international trade shapes Nigeria’s economy during the period 1999-2022. The vector error correction method (VECM) was employed to examine the impact, while Augmented Dickey-Fuller (ADF) unit root test was conducted to ensure the stationarity of the time series data, and the Johansen co-integration test to assess the long-run relationship between the dependent and independent variables. Our results show that all variables, were stationary at first difference. The Johansen cointegration test conclusively demonstrated the existence of a long-run relationship among the variables. Furthermore, the results from the VECM reveal that the coefficients of the lagged value of foreign direct investment inflows (FDII) and non-oil export exhibit negative relationship with RGDP. The coefficient of the lagged value of non-oil import (NOIM) and exchange rate (EXCR) has positive impact with RGDP. The study recommends that government should create the enabling environment for investors to thrive. This will help increase the number of both foreign and domestic investors investing in Nigeria, and the output will be increased for domestic consumption and exportation.

ASSESSING THE EFFECTIVENESS
OF THE OIL TRUNK PIPELINE CONSTRUCTION PROJECT:
A SCENARIO APPROACH
Authors: GRAKHOV Valery , VORONA Vadim
Published: July 2024

The article is devoted to the development of a scenario approach in assessing the effectiveness of a main oil pipeline construction project. A pressing issue is the formation of an integrated approach to assessing the effectiveness of the oil trunk pipeline construction project, in connection with the impact of various types of risks and uncertainties of the external environment (technical, economic, environmental). Based on this, a particularly important aspect is to study the impact of these various risks on the project and take into account the scenario approach in this (taking into account both the pessimistic scenario and the optimistic scenario for project implementation), which will improve the efficiency of the entire oil trunk pipeline construction project. The methodology proposed by the author, used when assessing the effectiveness of a main oil pipeline construction project, allows us to take into account the predictable uncertainty of the project's effectiveness. Unified integral indicators of the economic effect of the project for all three scenarios were developed on the basis of standardized indicators and their weighted significance. The most effective project for implementation has been identified, taking into account three scenarios, which, depending on one of the three implementation scenarios, will provide the best values of project performance indicators: net present value, profitability index, internal rate of return and payback period.

Abstract. Aviation is currently estimated to contribute ~3.5 % of the net anthropogenic effective radiative forcing (ERF) of Earth's atmosphere. The largest component of this forcing comes from contrail cirrus (also with a large associated uncertainty of ~70 %), estimated to be two times larger than the contribution from aviation CO2 emissions. Here we implement the contrail parameterisation previously developed for the USA NCAR (National Center for Atmospheric Research) Community Atmosphere Model (CAM) in the UK Met Office Unified Model (UM). By using for the first time the same contrail parameterisation in two different host climate models, this work investigates the impact of key features of the host climate model on quantifying contrail cirrus radiative impacts. We find that differences in the background humidity (in particular ice supersaturation) in the two climate models lead to substantial differences in simulated contrail fractions, with UM values being two to three times as large as those from CAM. We also find contrasting responses in overall global cloud fraction due to air traffic, with contrails causing increases and decreases in total cloud fraction in the UM and in CAM, respectively. The different complexity of the two models’ cloud microphysics schemes (i.e. single and double-moment cloud schemes in the UM and CAM, respectively) results in significant differences in the simulated changes in cloud ice water content due to aviation. When accounting for the difference in cloud microphysics complexity, we estimate the contrail cirrus ERF of the year 2018 to be 40.8 mWm−2 in the UM and 60.1 mWm−2 in CAM. While these two estimates are not entirely independent, they indicate a substantial (i.e. factor of ~2) uncertainty in contrail cirrus ERF from differences in the microphysics and radiation schemes of the two host climate models. We also find a factor of 8 uncertainty in contrail cirrus ERF due to existing uncertainty in contrail cirrus optical depth. We suggest that future work on the contrail cirrus climate impact should focus on better representing the microphysical and radiative contrail characteristics in different climate models and on improved observational constraints.

Abstract. Ozone (O3) pollution is posing significant challenges to urban air quality improvement in China. The formation of surface O3 is intricately linked to chemical reactions which are influenced by both meteorological conditions and local emissions of precursors (i.e., NOx and VOCs). The atmospheric environment capacity decreases when meteorological conditions deteriorate, resulting in the accumulation of air pollutants. Although a series of emission reduction measures have been implemented in urban areas, the effectiveness of O₃ pollution control proves inadequate. Primarily due to adverse changes in meteorological conditions, the effects of emission reduction are masked. In this study, we integrated machine learning model, the observation-based model and the positive matrix factorization model based on four years of continuous observation data from a typical urban site. We found that transport and dispersion impact the distribution of O3 concentration. During the warm season, positive contributions of dispersion and transport to O3 concentration ranged from 12.9 % to 24.0 %. After meteorological normalization, the sensitivity of O3 formation and the source apportionment of VOCs changed. The sensitivity of O3 formation changed from the NOx-limited regime to the transition regime between VOC- and NOx-limited regimes during the O3 pollution event. Vehicle exhaust became the primary source of VOC emissions after removing the effect of dispersion, contributing 41.8 % to VOCs during the pollution periods. On the contrary, the contribution of combustion to VOCs decreased from 33.7 % to 25.1 %. Our results provided new recommendations and insights for implementing O3 pollution control measures and evaluating the effectiveness of emission reduction in urban areas.

Published: July 2024

Abstract. Most recent cost-benefit Integrated Assessment Models have used only one reference scenario and focused on reducing mainly CO2 emissions. This goal may not adequately account for the uncertainties arising from diverse socioeconomic developments and the potential for mitigating the effects of emissions of individual greenhouse gases, aerosols, and pollutants. We developed an Integrated Assessment Model framework by combining a socioeconomic module with a reduced-complexity climate module. We represented the Shared Socioeconomic Pathways (SSP) scenarios by 1) calculating a new set of marginal abatement cost curves based on the most recent integrated assessment model, 2) creating a new SSP-dependent damage function based on process-based impact simulation results, and 3) extending the evaluation time to the year 2450. The cost-benefit analysis revealed that the SSP scenarios achieved various rates of control for emissions of individual greenhouse gases, aerosols, and pollutants. The result was diverse patterns of optimal temperatures, including maximum temperature achieved and stabilized temperature by the end of the evaluation period. The model simulations showed the importance of distinguishing options for reducing emissions of greenhouse gases based on distinct socioeconomic growth scenarios. We also show an example of a long-term socioeconomic projection spanning several centuries as well as a variety of socioeconomic assumptions for assessing climate change policies with long-term consequences.
Enigmatic Fe-Mn-fueled Anaerobic Oxidation of Methane in sulfidic coastal sediments of the Eastern Arabian Sea

Published: July 2024

Abstract. Anaerobic oxidation of methane (AOM) coupled with Fe-Mn reduction (Fe-Mn-AOM) is considered a globally important biogeochemical process in marine sediments in addition to sulfate-driven AOM (SO42−-AOM) responsible for the consumption of methane, a strong greenhouse gas. Most existing studies have emphasized the significance of Fe-Mn-AOM activities in sediments below the depth of the sulfate methane transition zone (SMTZ) with insignificant dissolved sulfide and sulfate concentrations in the porewaters. Here, we report for the first time enigmatic geochemical evidence of focused Fe-Mn-AOM activity across the SMTZ in the presence of high dissolved sulfide concentrations in a sediment core collected within the seasonal coastal hypoxic zone of the Eastern Arabian Sea (West coast of India (WCI)). The Fe-Mn-AOM activity is evident from the concurrent decrease in CH4 concentrations, d13CCH4 and d13CDIC values coupled with the enrichment of porewater Fe2+ and Mn2+ concentrations at multiple depths below the seafloor. Since neither CH4 nor reactive Fe appears to be the limiting factor controlling the Fe-Mn-AOM activity, we hypothesize that the focused Fe-Mn-AOM at multiple depths is likely fueled by the localization of metal-reducing and methanotrophic microbial communities, leading to biogeochemical heterogeneity in a dynamic seasonally hypoxic coastal environment sensitive to climate change. This study highlights new insight into CH4-S-Fe-Mn biogeochemical cycling with far-reaching implications in climate studies linked to the estimation of sedimentary methane production and consumption.
Gravity waves as a mechanism of troposphere–stratosphere–mesosphere coupling during sudden stratospheric warming
Authors: Jovanovic Gordana
Published: July 2024

Abstract. The propagation of gravity waves (GW) and their role in the coupling of the troposphere–stratosphere–mesosphere atmospheric layers during sudden stratospheric warming (SSW) are studied. A standard set of hydrodynamic equations (HD) is used to derive the analytical dispersion equations and the GWs reflection coefficient. These equations are applied to the troposphere–stratosphere and stratosphere–mesosphere boundaries to analyze which part of the GWs spectra has the greatest chance of crossing them and affecting the dynamics of the upper atmosphere. We found that the GWreflection coefficient at the troposphere–stratosphere boundary increases significantly during SSW. This is not the case for the reflection coefficient at the stratosphere–mesosphere boundary when the reflection coefficient decreases compared to its value in the no–SSW case. The generation of GWs in the stratosphere during the SSW is responsible for the reduction of the reflection coefficient. However, these additional GW fluxes are not sufficient to compensate for the reduction of GW fluxes coming from the troposphere to the mesosphere. As a result, there is mesospheric cooling accompanied by SSW events.

Published: July 2024

Abstract. Quantifying global cloud condensation nuclei (CCN) concentrations is crucial for reducing uncertainties in radiative forcing resulting from aerosol-cloud interactions. This study analyzes two novel, independent, open-source global CCN datasets derived from spaceborne Cloud Aerosol Lidar with Orthogonal Polarization (CALIOP) measurements and Copernicus Atmosphere Monitoring Service (CAMS) reanalysis and examines the spatio-temporal variability of CCN concentrations pertinent to liquid clouds. The results reveal consistent large-scale patterns in both CALIOP and CAMS datasets, although CALIOP values are approximately 79 % higher than those from CAMS. Comparisons with existing literature demonstrate that these datasets effectively bound the regionally observed CCN concentrations, with CALIOP typically representing the upper bound and CAMS the lower bound. Monthly and annual variations in CCN concentrations obtained from the two datasets largely agree over the Northern Hemisphere and align with previously reported variations. However, inconsistencies emerge over pristine oceans, particularly in the Southern Hemisphere, where the datasets show not only opposing seasonal changes but also contrasting annual trends. A closure study of trends in CCN and cloud droplet concentrations suggests that dust-influenced and pristine-maritime environments primarily limit our current understanding of CCN-cloud-droplet relationships. Long-term CCN observations in these regions are crucial for improving global datasets and advancing our understanding of aerosol-cloud interactions.

Abstract. This paper describes the process of creating a global survey of experts to evaluate drought resilience indicators. The lessons learned include five main points: (1) the heterogeneity in the conceptual background should be minimized before the construction of the survey; (2) large numbers of indicators decrease the engagement of respondents through the survey, and ways to apportion indicators whilst maintaining reliability should be considered; (3) it is necessary to design the survey to balance response rate and accuracy; (4) the survey questions should have clear statements with a logical and flowing structure; and (5) reaching experts with different domain experience and representing different regions is difficult but crucial to minimize biased results.
Multi-dimensional, Multi-Constraint Seismic Inversion of Acoustic Impedance Using Fuzzy Clustering Concepts
Authors: Jahanjooy Saber , Hashemi Hosein , Bagheri Majid
Published: July 2024

Abstract. In the process of transforming seismic data into vital information about subsurface rock and fluid properties, seismic inversion is a crucial tool. This motivates researchers to develop several seismic inversion methods and software. Since the seismic data are band-limited, seismic inversion is ill-posed, and the results are not unique, each method tries to use initial information and assumes expected conditions for the results. Satisfying a general low-frequency trend and having a smooth model or step-wise results are some of the assumptions that these methods add as constraints to the inversion process. Well-logs, geological studies, and models from other geophysical methods can add important insight into the seismic inversion results. We introduce an objective function that applies the clustering properties of the prior information as a constraint to the seismic inversion process as well as other common constraints. An optimal solution to the objective function is explained. We applied the Gustafson-Kessel fuzzy C-means as one of the possible clustering methods for clustering term. Numerical synthetic and real data examples show the efficiency of the proposed method in the inversion of seismic data. In addition to the acoustic impedance model, the proposed seismic inversion method creates reliable deconvolved and denoised versions of the input seismic data. Additionally, the membership section output from the inversion process shows high potential in the seismic interpretation. Further research on selecting an optimum fuzziness, updating wavelet, and the potential of the membership sections to track horizons, distinguish sequences and layers, identify possible contents of the layers, and other possible applications are recommended.
Improving ensemble data assimilation through Probit-space Ensemble Size Expansion for Gaussian Copulas (PESE-GC)
Authors: Chan Man-Yau
Published: July 2024

Abstract. Small forecast ensemble sizes (< 100) are common in the ensemble data assimilation (EnsDA) component of geophysical forecast systems, thus limiting the error-constraining power of EnsDA. This study proposes an efficient and embarrassingly parallel method to generate additional ensemble members: the Probit-space Ensemble Size Expansion for Gaussian Copulas (PESE-GC; “peace gee see”). Such members are called “virtual members”. PESE-GC utilizes the users' knowledge of the marginal distributions of forecast model variables. Virtual members can be generated from any (potentially non-Gaussian) multivariate forecast distribution that has a Gaussian copula. PESE-GC's impact on EnsDA is evaluated using the 40-variable Lorenz 1996 model, several EnsDA algorithms, several observation operators, a range of EnsDA cycling intervals, and a range of forecast ensemble sizes. Significant improvements to EnsDA (p<0.01) are observed when either (1) the forecast ensemble size is small (≤20 members), (2) the user selects marginal distributions that improve the forecast model variable statistics, and/or (3) the rank histogram filter is used with non-parametric priors in high-forecast-spread situations. These results motivate development and testing of PESE-GC for EnsDA with high-order geophysical models.

LEGAL REGULATION OF THE RIGHT OF OWNERSHIP OF NATURAL RESOURCES IN THE ADOPTION OF AMENDMENTS TO THE CONSTITUTION OF THE REPUBLIC OF KAZAKHSTAN
Authors: Kurmanova Aigul Kuanyshevna
Published: July 2024

The article considers some issues of legal regulation of the ownership of natural resources. Analysis of the problems of the content of the real right to natural resources under consideration and related legal relations, as well as consideration of effective recommendations for its development and improvement based on the study of the fundamental principles is the purpose of writing the work. The relevance of the topic is justified by the social value of the realization of the right of ownership of natural resources for the population and the state in terms of meeting their needs. The use of general and special research methods in interaction is necessary to substantiate the author's opinion. The specificity of the object of research consists in the impossibility of isolating a separate natural resource from the environment, therefore it must be considered in interaction with it. The paper deals with the content of the concept of ownership of natural resources, which is complicated by the lack of a definition of the concept of "natural resources" in the legislation. The application of this institution in legislation and law enforcement practice along with the concept of "components of the natural environment" creates difficulties, especially in determining the priority in regulating the ownership of natural resources by civil or environmental (natural resource) legislation. This issue becomes relevant in the light of the adoption of amendments to the Constitution, in particular, regarding article 6. The constitutional provision on the ownership of natural resources by the people requires amendments to other normative legal acts regulating relevant issues in relation to this right. By the resolution of the Constitutional Council, this property is public law. In this regard, the question of applying the state property regime to this property may be controversial, since state and public property are different concepts in which state and public interests are the objects of the goals pursued.

Dampak teknologi yang semakin pesat salah satunya adalah peralihan industri investasi dari bentuk fisik ke digital. Dalam perkembangannya pemilik aset kripto kebingungan dalam menetukan pilihannya. Pengalihan asetnya kepada ahli warisnya, karena di Indonesia sendiri belum memiliki aturan penggunaan aset kripto sebagai warisan. Aset kripto yang memanfaatkan keamanan terdesentralisasi pada jaringan blockchain. Artinya, tidak ada pihak yang bertindak sebagai perantara dalam transaksi tersebut. Hal ini mempunyai kelemahan. Jika pemilik aset tiba-tiba meninggal dan warisan aset kriptonya tidak dipersiapkan dengan baik, keamanan blockchain yang tinggi akan menghalangi ahli warisnya untuk mengakses aset tersebut. Harta tersebut tidak akan hilang, namun tentu saja akan menimbulkan permasalahan baru bagi ahli warisnya. Jika tidak ada yang mengetahui cara mengakses jaringan, masalah baru terkait pewarisan dapat muncul. Dalam penelitian ini akan mengkaji: 1) Pembagian harta waris berbentuk kripto dan 2) Aset Hukum aset kripto dalam islam. Penelitian ini menggunakan metode kualitatif dengan pendekatan kepustakaan (library research). Hasil penelitian ini memperjelas bahwa pembagian harta waris berbetuk kripto ada penggolongan-penggolongannya dan ada tahapan-tahapannya.

Di wilayah Provinsi Maluku Utara khususnya pada Kabupaten Pulau Taliabu terdapat Sungai Samada yang berada di Kecamatan Taliabu Utara yang berada dekat dengan desa Padang dan Desa Natang Kuning. Sungai tersebut merupakan salah satu sungai yang sering kali terjadi banjir yang kerap meresahkan masyarakat yang akan melintasi sungai karena belum adanya sarana jembatan permanen sebagai akses menuju kecamatan lain atau ke Ibukota Kabupaten Bobong. Tujuan penelitian ini adalah melakukan pemodelan banjir yang disebabkan oleh luapan sungai Samada di Kecamatan Taliabu Utara Kabupaten Pulau Taliabu serta melihat cakupan wilayah genangan banjir. Metode pemodelan banjir menggunakan pendekatan hidrolika dalam mensimulasikan debit air pada sungai menggunakan software HEC-HMS, serta melakukan visualisasi daerah genangan banjir serta area terdampak banjir menggunakan pendekatan GIS dengan software HEC-RAS. Besar debit banjir yang didapat berdasarkan analisa Hidrologi menggunakan HEC-HMS untuk kala ulang Q5th, Q10th, Q25th pada desa Padang dan desa Natang Kuning masing-masing sebesar 49.1m3/s, 67.4m3/s, 92.5m3/s dan 104.7m3/s, 144.2m3/s, 198.4m3/s. Hasil pemodelan genangan banjir menggunakan HEC-RAS berdasarkan banjir kala ulang Q5th, Q10th, Q25th yang paling berdampak adalah pada desa Padang sehingga diperlukan tanggul sungai. Sedangkan pada desa Natang Kuning luas genangan banjir tidak sampai ke pemukiman karena berjarak cukup jauh dari sungai dan elevasi lebih tinggi.

Background: Abdominal hysterectomy has been largely replaced by minimally invasive surgery. Nevertheless, in some situations, a minimally invasive intervention must be converted to laparotomy. Factors associated with conversion to laparotomy are still a matter of debate.

Objective: The aim of this study was to evaluate the clinicopathological factors associated with the conversion of laparoscopic hysterectomy to laparotomy.

Material and Methods: The risk factors for conversion of a preplanned laparoscopic procedure to laparotomy were retrospectively evaluated in 441 patients undergoing a hysterectomy for a benign indication between 2016 and 2020. Associations between the clinical factors were analysed using Pearson’s chi-square and Fisher’s exact test, and predictive values for conversion were assessed through multivariate logistic regression.

Result: Conversion occurred in 32 (7.3%) of the cases. Significant differences were detected for uterus weight (576.9gr vs 174.6gr, p<0.001), myoma size (7.0 cm vs. 1.8 cm, p<0.001), and presence of triple diagnosis consisting of leiomyoma, adenomyosis uteri, and pathological adnexal findings (p<0.013). The conversion resulted in prolonged surgery time (181.6 min vs. 119.6 min, p<0.001) and hospital stay (4.0 vs. 3.1 days, p<0.001), as well as an increased rate of wound infection (15.6% vs. 3.4%, p<0.001). A 10g increase in uterus weight raised the risk of conversion by 7.0%, and a 1cm increase in myoma diameter by 7.3%, while adnexal pathologies and extensive adhesions increased the odds of conversion to laparotomy threefold (ORs of 3.2, 1.09-9.6 and 3.6, 1.3-10.0, respectively).

Conclusion: Uterus weight, myoma size, the coexistence of pathological adnexal findings, and non-physiological adhesions are independent risk factors for conversion.

What is new? This study provides data regarding the risk and factors increasing this risk for conversion to laparotomy during laparoscopic hysterectomy.

Published: July 2024

Background: Laparoscopic myomectomy is increasingly considered the gold standard uterine preserving procedure and has well documented benefits over the open approach. Barriers that women have in accessing the most appropriate treatment need to be addressed to ensure optimal patient care and outcomes.

Objectives: To analyse rates of open and laparoscopic myomectomy at a large NHS trust and identify how many cases could potentially have been performed laparoscopically, and any variation between sites.

Materials and methods: A retrospective review of preoperative imaging reports and a surgical database containing information for all myomectomies performed between 1st January 2015 and 31st December 2022.

Main outcome measures: Number of procedures suitable for alternative surgical approach; length of hospital stay; estimated blood loss; cost differences.

Results: 846 myomectomies were performed; 656 by laparotomy and 190 by laparoscopy. 194/591 (32.8%) open myomectomies could have been performed laparoscopically and 26/172 (15.1%) laparoscopic myomectomies may have been better performed via an open approach. Length of hospital stay, and estimated blood loss were significantly higher in the open group. Had cases been performed as indicated by pre-operative imaging, the cost differences ranged from -£115,752 to £251,832.

Conclusions: There is disparity in access to the gold standard care of laparoscopic myomectomy. Due to multifactorial reasons, even at sites where the rate of laparoscopic myomectomy is high, there is still underutilisation of this approach. It is clear that there is scope for change and “levelling up” of this imbalance.

What is new? Robust pathways and guidelines must be developed, and more laparoscopic surgeons should be trained to optimise care for women with fibroids.
Understanding consumers’ digital piracy behaviour: Explanation and prediction

Published: July 2024

This research aims to examine the explanatory and predictive power of seven theoretical models based on neutralisation theory, perceived risk theory, the theory of interpersonal behaviour, the theory of reasoned action, the theory of planned behaviour, the theory of self-regulation, and the norm activation theory. A total of 247 usable data were collected through a survey and analysed using partial least squares structural equation modelling. The in-sample and out-of-sample predictive power of each model was assessed. The results indicate that there are different factors influencing consumers’ intentions to pirate digital products. Among the seven theories, the theory of interpersonal behaviour ranks first, and perceived risk theory last in terms of explanatory and predictive power. This study is the very first to examine the explanatory and predictive power of seven different theoretical models using advanced PLS-SEM techniques.

Published: July 2024

Previous studies have highlighted a strong relationship between mechanical lower limb muscle function and TeamGym performance, specifically in terms of difficulty scores in trampette and tumbling disciplines. To date, no intervention study has explored whether enhancing lower limb muscle function can translate to improved TeamGym performance. We recruited eleven national-level TeamGym athletes (four males, seven females) for a quasi-experimental intervention spanning six weeks. The regimen comprised strength training sessions thrice weekly, emphasizing power and maximum strength. Pre- and post-intervention assessments included countermovement jumps, drop jumps, leg press power, 20m sprints, jump and reach, as well as video analyses of trampoline and tumbling performances. In line with prior research, our study uncovers significant correlations between physical test outcomes and TeamGym performance. Notably, leg press power exhibited a robust association with trampoline performance (r=0.95, p<0.001), while drop jump results correlated strongly with tumbling performance (r=0.72, p<0.05). Post-training, only the intervention group displayed a statistically likely uptick in leg press power. Additionally, the intervention group saw an average increase of 0.15±0.2 points in difficulty, contrasting with the control group's negligible change (0.0±0.2).Given the limited sample size in this preliminary pilot study, the results warrant cautious interpretation. Nonetheless, they resonate with prior findings, suggesting that augmenting an athlete's mechanical lower limb muscle function through targeted strength and power training can beneficially influence national-level TeamGym performance.
From laboratories to Museum: the trajectory of the mineralogy collection of the Escola de Minas de Ouro Preto
Authors: Jotta Carlos
Published: July 2024

The paper presented is the result of the author's doctoral research, which included an
excerpt on the formation of the mineralogy collection of the former Escola de Minas de Ouro
Preto, currently the Escola de Minas da Universidade Federal de Ouro Preto. This analysis aims
to map the trajectory of the collection from its entry to the museumization of the samples. As a
methodological path, the exploratory research collected information in online repositories and in
the archives of the Escola de Minas da UFOP and the Museu de Ciência e Técnica da Escola
de Minas da UFOP. This study sought to answer how the set of minerals present in the
Mineralogy Office contributed to the training of mining engineers in the 19th and early 20th
centuries. The results show a movement of collections from other national and foreign
institutions and their didactic use even after their museumization in 1930.

The main objective of the Study was to assess the implication of transfer pricing scheme on manufacturing companies’ profitability in Tanzania. Specifically aimed to determine the cause and effect relationship of interest payments on related party loans, payment of service fee on intercompany services and royalty payments for the use of related party intangible properties on manufacturing companies’ profitability. The study adopted a positivism philosophy and adopted deductive reasoning. The secondary data was collected from 4 manufacturing firm’s annual report for the period of 2013 to 2022. The study used multiple linear regression for data analysis and this was done through STATA software version 14.2. The study findings show that Interest payments on related party loans has significant negative effect on manufacturing companies’ profitability. Furthermore, the result shows that payment of service fee on intercompany services has no significant effect on manufacturing companies’ profitability. Finally, Royalty payments for the use of related party intangible properties has significant positive effect on manufacturing companies’ profitability. Current study recommends that, for companies to comply with relevant transfer pricing regulations, close supervision by taxing authority (TRA) is considered necessary to reduce unhealthy transfer pricing practices. Also, study recommends that interest payments on related party loans should be set at values that would not negatively impact the financial performance of manufacturing firms in Tanzania. Related party companies should set transfer price to reflect the ALP (arm’s-length price) that unrelated parties would agree to in the same circumstances for transfer or use of similar intangible property. Moreover, the study recommends government to put in place monetary policies that will facilitate financial performance of listed manufacturing companies and ensure proper regulation of the financial institutions so as to provide adequate credit facilities for the manufacturing firms in Tanzania.
