Authors: Nunes Marcos Vinicius , Ottoni André Luiz
Published: October 2024

The inspection and maintenance of solar panels face significant challenges due to the dangers involved in checking for potential defects in photovoltaic panels. However, the advancement of studies to facilitate this verification is limited by the lack of image datasets for training algorithms that can perform this task. Based on this principle, the use of Convolutional Neural Networks (CNNs) for training and Data Augmentation for creating artificial data from real images is common. With that said, this work aims to explore configurations and models of Data Augmentation for the classification of defects in solar panels using CNNs. The proposed methodology consists of four experimental stages, where the application of Zoom, rotation, horizontal displacement, and vertical displacement transformations are evaluated, followed by filtering the best results and combining them to find the ideal classification model. The performance of the model proved to be most effective when using a 35-degree rotation for creating artificial images, thus achieving an 88% F1-Score and 87.64% accuracy.

The oral route of drug administration is often preferred by patients and healthcare providers due to
its convenience, ease of use, non-invasiveness, and patient acceptance. However, traditional oral dosage forms
have several limitations, including low bioavailability, limited drug loading capacity, and stability and storage
issues, particularly with solutions and suspensions. Over the years, researchers have dedicated considerable effort
to developing novel oral drug delivery systems to overcome these limitations. This review discusses various
challenges associated with oral drug delivery systems, including biological, pharmaceutical, and physicochemical
barriers. It also explores common delivery approaches, such as gastroretentive drug delivery, small
intestine drug delivery, and colon-targeting drug delivery systems. Additionally, numerous strategies aimed at
improving oral drug delivery efficiency are reviewed, including solid dispersion, absorption enhancers, lipidbased
formulations, nanoparticles, polymer-based nanocarriers, liposomal formulations, microencapsulation,
and micellar formulations. Furthermore, innovative approaches like orally disintegrating tablets (ODT), orally
disintegrating films (ODF), layered tablets, micro particulates, self-nano emulsifying formulations (SNEF),
and controlled release dosage forms are explored for their potential in enhancing oral drug delivery efficiency
and promoting patients’ compliance. Overall, this review highlights significant progress in addressing challenges
in the pharmaceutical industry and clinical settings, offering novel approaches for the development of
effective oral drug delivery systems.

Cancer Cells
Authors: Antoszczak Michal , Mielczarek-Puta Magdalena , Struga Marta , Huczynski Adam
Published: October 2024

Background:

Since it was discovered that a natural polyether ionophore called salinomycin (SAL)
selectively inhibits human cancer cells, the scientific world has been paying special attention to this compound. It
has been studied for nearly 15 years.

Objective:

Thus, a very interesting research direction is the chemical modification of SAL structure, which could
give more biologically active agents.

Methods:

We evaluated the anticancer activity of (thio)urea analogues class of C20-epi-aminosalinomycin (compound
3b). The studies covered the generation of reactive oxygen species (ROS), proapoptotic activity, cytotoxic
activity, and lipid peroxidation in vitro.

Results:

Thioureas 5a-5d showed antiproliferative activity against selected human colon cancer cell lines greater
than that of chemically unmodified SAL, with a 2~10-fold higher potency towards a metastatic variant of colon
cancer cells (SW620). Mechanistically, SAL derivatives showed proapoptotic activity in primary colon cancer
cells and induced the production of reactive oxygen species (ROS) in these cells. In SW620 cells, SAL derivatives
increased lipid peroxidation with a weak effect on apoptosis and low ROS formation with cytotoxic effects
followed by cytostatic ones, suggesting different modes of action of the compounds against primary and metastatic
colon cancer cells.

Conclusion:

The results of this study suggested that urea and thiourea derivatives of SAL provide promising
leads for the rational development of new anticancer active agents.

Published: October 2024

BACKGROUND

Individuals with non-Western backgrounds consistently exhibit a higher risk of type 2 diabetes (T2D) compared with ethnic Danes. Factors such as health behavior, limited healthcare access, and social determinants of health often contribute to this disparity. Culturally sensitive interventions are crucial, yet effective interventions for managing T2D in non-Western populations re-main limited.

OBJECTIVE

This study examines the effect of a one-year person-centered and culturally sensitive intervention on improving glycemic control (HbA1c) among individuals with T2D and non-Western backgrounds. The secondary objectives are to improve diabetes management and overall well-being.

METHODS

The present study is designed as a two-arm randomized controlled trial. 96 women and men with T2D (HbA1c≥53 mmol/mol) speaking either Arabic, Turkish, or Urdu as their native language will be randomized for one year to an intervention group (person-centered and culturally sensitive course of treatment) or a control group (usual care) in a 1:1 ratio in Denmark. Assessments are scheduled at baseline and one year. The primary outcome is HbA1c while lipids, blood pressure, and patient-reported outcomes including well-being, diabetes management, health literacy, and use of and adherence to diabetes medication are secondary outcomes. Feasibility and satisfaction are evaluated using interviews. The study is approved by the Ethics Committee of the Capital Region of Denmark (H-23042245).

RESULTS

A 5.0 mmol/mol (0.5%-DCCT) change in HbA1c is the minimally important difference, requiring 88 participants. To allow for uncertainties and dropouts, the total was increased to 96. As of October 2024, 70 participants have been recruited, with recruitment ongoing until March 2025. Data collection will continue until December 2025, with the first results expected by March 2026.

CONCLUSIONS

This study will contribute to the limited knowledge regarding the effects of person-centered and culturally sensitive treatment approaches for T2D in individuals with a non-Western background. The study employs a robust methodological design and will present an alternative avenue for man-aging T2D and improving overall well-being. The study offers valuable insights into the experiences of participants and healthcare professionals, including potential obstacles and strategies for implementation in outpatient clinics.

Published: October 2024

Key Points

CKD-associated pruritus is highly prevalent among peritoneal dialysis patients.

Pruritus is associated with reduced health-related quality of life, and the composite of mortality and transfer to hemodialysis for peritoneal dialysis patients.

Efforts to better identify and manage pruritus in this population are needed.

Background

Pruritus is common in hemodialysis patients. Less is known about the prevalence and outcomes of pruritus among patients receiving peritoneal dialysis (PD). Herein, we describe the prevalence of pruritus and its associations with patient-reported outcomes (PROs) and mortality/transfer to hemodialysis.

Methods

We analyzed a multicenter, international cohort of PD patients enrolled in the PD Outcomes and Practice Patterns Study from 2014 to 2022. Pruritus was assessed at entry into the PD Outcomes and Practice Patterns Study with a single-question Likert Scale capturing the extent to which patients were bothered by itch ranging from 1: not at all to 5: extremely. The kidney disease quality of life-36 and the Center for Epidemiological Studies Depression Scale assessed various PROs. Moderate-to-extreme pruritus was defined as a Likert scale score ≥3. The associations of pruritus with PROs were assessed using linear/logistic regression where appropriate. Death or hemodialysis transfer was assessed using multivariable Cox regression models.

Results

Overall, 5535 patients from eight countries were included; 43% had moderate-to-extreme pruritus which was the highest in Thailand (50%) and the lowest in the United States (33%). The adjusted odds ratios of moderate-to-extreme pruritus were higher for diabetes, low albumin, and elevated phosphorus but lower for residual urine volume (adjusted odds ratio, 0.98 per 200 ml increase in 24-hour urine volume; 95% confidence interval, 0.96 to 1.00; P = 0.05). Patients with extreme pruritus had the lowest mental and physical health component scores and a higher burden of other PROs including restless legs and disturbed sleep. Overall, 921 patients died and 1150 were transferred to hemodialysis. Patients with moderate-to-extreme pruritus were at higher adjusted risk for death or hemodialysis transfer (adjusted hazard ratio, 1.12; 95% confidence interval, 1.02 to 1.23; P = 0.02) with similar point estimates for each subcomponent of the composite outcome.

Conclusions

Pruritus is highly prevalent in PD and associated with poor health outcomes. Efforts to better identify and manage pruritus should be considered in this population.

Introduction: The diagnosis of canine visceral leishmaniasis (CVL) is of great importance in the control of visceral leishmaniasis, a disease that is neglected  worldwide and represents a significant public health problem. Enzyme-linked immunosorbent assay (ELISA) test is widely used because of the possibility of large-scale diagnosis and low cost. Objective: The objective of this study was to optimize the stoichiometry of the conjugate used in the EIE/CVL kit; for this purpose, some conjugation and monitoring parameters were modified through molecular exclusion chromatography to improve the final product. Method: The conjugate produced by Bio-Manguinhos was optimized by purification using SEC gel filtration chromatography and evaluated using the EIE-leishmaniasis-visceral-canine-Bio-Manguinhos kit (EIE-LVC). The conjugates were produced with different stoichiometries (IgG X peroxidase): current conjugate, optimized conjugate and optimized and purified conjugate. Results: The results obtained were validated using the manual Canine Visceral Leishmaniasis test. The homogeneity of the conjugate means in the ELISA test was evaluated using the chi-square test, thereby demonstrating the normality and reliability of the data. Based on statistical data, positive samples obtained by the ELISA test showed homogeneity at a significance level of 0.05, i.e. a data reliability level of 95%. The optimization of the production of the canine anti-IgG conjugate, an extremely important component used in the composition of the Bio-Manguinhos EIE LVC KIT, contributed to ensuring the quality of the kit and improving the diagnosis of canine visceral leishmaniasis disease, making it more sensitive and inexpensive for public health. Conclusions: This work demonstrates that it is possible to optimize the anti-IgG canine peroxidase (HRP) conjugate used in the EIE CVL kit to make it more specific and ultimately more economical.
Party Autonomy in The Regulation of Transfer of Title: Comparative Analysis
Authors: Oleynikov M. A.
Published: October 2024

The absence of a unified material legal regulation of the transfer of property rights is determined by the presence of fundamental contradictions in the approaches of various legal systems to this issue. The lex rei sitae connecting factor is not the optimal way to regulate the transfer of ownership of movable property in cross-border transactions. Conflict mobile is one of the cases, when determining the statute of a movable property by the law of its location is difficult and leads to an unfair result. The right of the parties to a contract in cross-border relations to freely choose the legal order regulating transfer of ownership is one of the ways to overcome the disadvantages of conflict-of-laws regulation of the transfer of ownership. However, such a manifestation of the party autonomy is not allowed in all legal systems and is not a generally accepted approach. The purpose of the study is to reveal the difficulties of the legal order in case of implementation of the party autonomy in the sphere of transfer of property rights, as well as to identify ways to overcome them. The party autonomy is practically analyzed on the example of the legal systems of Russia and CIS, Switzerland, the Netherlands, China. The choice of the legal order applicable to the transfer of ownership is not an extension of the scope of the contract statute, but represents party autonomy in relation to the real statute. Consequently, party autonomy interferes with the specific issues of property law. The analysis shows us that the party autonomy with certain restrictions is permissible for regulating transfer of ownership and serves an instrument for overcoming difficulties caused by the use of lex rei sitae connecting factor in a number of cases. However, allowing parties to an international transaction to choose the legal order applicable to the transfer of ownership raises the question of the effect of the choice against third parties. The article outlines ways to solve this problem.

In relation to the sphere of legal protection the author considers two legal phenomena: “digital self-protection” and “digital protection of rights”. Relaying on examples of actions taken by parents in order to protect the children’s rights on Internet, the author comes to the conclusion that the digital methods of protecting the right that exist today in practice can be considered by modern jurisprudence as alternative ways to protect the right or form a new legal institution of “digital self-protection”.
Regulation and protection of personal health data in the AI era: international experience
Authors: Galkina N. M. , Kuznetsova D. V.
Published: October 2024

Artificial intelligence is actively taking over sphere after sphere and particular successes and achievements can be seen in the medical sector and medical technology. However, the introduction of AI raises a number of practical and ethical issues. One of the main ones is the issue of handling personal data, as access to a large number of patients’ health data plays a key role in the development and use of AI in medicine. The most convenient solution for their use is to anonymise them beforehand. However, with anonymisation, there is a risk of re-identification and the potential for loss of data informativeness may be lost. In the framework of this article the experience in the sphere of legal regulation of personal health data handling when using artificial intelligence systems in medicine is considered in the example of the USA, EU and Singapore. Each country is endeavoring to strike a balance between the protection of personal data privacy and the advancement of technological innovations. The analysis suggests that the emphasis on artificial intelligence development necessitates specific premises in the domain of personal data protection. Conversely, stringent standards for the protection of personal data could potentially exert a restrictive influence.

Authors: Eaton Ben , Henningsson Stefan , Hedman Jonas , Schneider Maximilian , Johansen Benny Boye
Published: October 2024

In the realm of modern technology, Application Programming Interfaces (APIs) are becoming the cornerstone component of the digital ecosystem, resulting in the emergence of the API economy. This transformation is driven by firms leveraging APIs for cost reduction, broadening their audience reach, and monetizing services - enabling value creation through the exchange of information and services within and between organizations. Following the proliferation of APIs, even traditional firms are evolving into software producers, and are now on a journey from ad-hoc exploration of APIs to establishing an organization-wide approach to APIs at scale. In this context, APIs increasingly become value-adding products. With their expanding role in businesses, the quality of APIs has become a crucial factor in enterprise success, demanding a systematic and exhaustive approach to API development. Thus, the management of APIs as a value-creating product extends from a purely technical concern at the discretion of individual engineers to a managerial matter.

Determinants of financing decisions for renewable energy projects: A case study
Authors: Do Thuy Thi Thu , Tran Tuan Minh , Le Hoang Duc , Tran Long Phi , Cao Giang Truong
Published: October 2024

Renewable energy sources have never been more affordable and are now significantly undercutting fossil fuels as the world’s cheapest source of energy. Otherwise, it can benefit the environment, economy and society in the long term. However, financing and investment barriers play an important role in order to encourage renewable energy projects in Vietnam. In this research study on factors affecting investment decisions in renewable energy, along with behavioural and institutional theories, the authors have pointed out that financing decisions (FD) for energy projects in Vietnam are also influenced by non-financial factors. In this paper, we developed the model by using four factors: a priori beliefs (PB), institutional influence from legal obligations (IO), institutional influence from normative sources (IN), and knowledge of renewable energy operational context (KC). Structural equation modelling (SEM) is used to analyze determinants of the decision-making of financial institutions. Similar to Giang (2022), our result shows the important role of the PB in the effectiveness of renewable energy’s existing policies and technological adequacy, KC as well as the IN in renewable energy FD of institutional investors. Meanwhile, IO does not impact the investors’ willingness to finance renewable energy projects.

Published: October 2024

Fast consumption of conventional ingredients of concrete and waste generated due to demolishing old buildings is a multi-fold problem in the concrete industry. Hence the sustainable alternative of it is the need of the day. In this research work effect of binary blending of demolished waste and fly ash on the flexural strength of plain concrete prism is presented. The properties of aggregates and cement are evaluated. The physical and chemical properties of fly ash were determined. Recycled aggregates from demolished waste with different mix ratios (1:2:4 and 1:1.5:3) were used. Optimization of recycled aggregates; by evaluating concrete cylinders in 12 batches; showed 35% as optimum. At the optimum dosage of recycled aggregates fly ash was used from 2.5% to 15% with an increment of 2.5% to optimize its dosage. Compressive strength test of the standard-size cylinders and their comparison with control concrete showed a 10% dosage of a fly as the optimum percentage to replace the cement in the concrete matrix. Using both optimized dosages of recycled aggregates and fly ash prism specimens of900mmx150mmx300mm were cast in four batches. The beam specimens were cured for 28 days followed by an evaluation of flexural strength and deflection under centric load in the universal testing machine. Test results of flexural strength (only 15% loss) showed good potential for both waste materials in the concrete matrix. Recycled aggregate with higher parent strength showed better performance than its other counterparts. With higher-strength recycled aggregates residual flexural strength was recorded as equal to 93%. For all specimens recorded deflection was within the allowable limits of ACI-318.

Pakistan has significant geothermal potential but due to poor energy management and low utilization of rich geothermal energy, the country is ranked among the energy deficient nations in the world. In this study, integrated geophysical techniques were used to assess the geothermal energy potential of various hot springs in the Sindh province. The study revealed that Naing Shareef and Gaji Shah hot springs have remarkable potential for geothermal energy having pool water temperature of 43 °C and 45 °C, respectively. Geophysical resistivity survey was carried out at both Naing Shareef and Gaji Shah hot spring to determine depth, thickness and quality of thermal water. At Naing Shareef hot spring, only a single thermal aquifer zone has been pinpointed within the shale composition of the Oligocene Nari Formation, and it is on average 55.07 m depth and 29.8 m thick. At an average depth of 100.66 m and an aquifer thickness of 77.03 m, the Gaji Shah hot springs exclusively possess a thermal aquifer region established within the sandstone composition of the Oligocene Nari Formation.
The perception of complex engineering problems among engineering teachers and students: A case study
Authors: Baig Khurram Shahzad , Asghar Usman , Ahmad Fazeel , Khan Waqas Ahmad
Published: October 2024

The complex engineering problems (CEPs) are characterized by challenges such as: a) involving extensive or inconsistent, incompatible data from engineering and other offshoots, b) unable to be solved in the absence of in-depth engineering knowledge. The engineering teachers are not found successful in the design of a CEP because it does not touch the real issues from industry and / or environment. Therefore, the expertise of applicable skill cannot be evaluated and the reason behind this failure is the lack of or poor intellectual perception of the attributes of CEPs among the teachers. In order to help teachers, the relation between attributes, knowledge profiles and CEPs is elucidated in this work by giving examples. The main objective of this article is to establish an understanding of the  student’s level of perceiving a complex engineering problem with respect to the learning domain. The Survey was conducted among 70 participants and the quantitative approach employed, utilizing a questionnaire survey and interviewing teachers to gather data from respondents selected through random probability sampling. It is concluded that Industrial training (like apprenticeships), laboratory practices and final year design project are good tools for the complex engineering activities/ exercises. The results obtained in the case study were found promising, therefore, it is recommended to extend this study by using various engineeringinstitutions to ascertain a framework on CEP solving. skills.

Published: October 2024

Wind energy's significance lies in its contribution to electricity production. Accurate wind speed prediction is crucial for precisely forecasting electricity generation, enhancing its overall importance. For the wind speed prediction two methods are developed in this paper that are the Linear Regression Method and Convolutional Neural Networks (CNNs). Linear regression makes a linear relation between input and output which are used to predict continuous outcomes. The second proposed leverage hierarchical feature extraction through convolutional layers, enabling them to excel at tasks like pattern recognition by capturing spatial patterns and hierarchies of information. Hyperparameter tuning is applied on both the models to minimize the errors. Then both the model’s performances are compared under different error matrices including MAE, RMSE, MSE and MAPE. The observations indicate that both the Linear Regression Model and CNN models are capable of forecasting wind speed However, the Linear Regression Model after Hyperparameter tuning performs better in terms of the calculated errors.
Are some neutral liners more neutral than others? An ex vivo morphological analysis of acetabular liners classified as “neutral”
Authors: Ochoa José Á , Neuvonen Perttu S , Hyttinen Jari , Viik Jari , Eskelinen Antti P
Published: October 2024

Background and purpose: In contemporary total hip replacement (THR), dislocation is one of the most common complications. At our institution, the cause of an increase in the dislocation rate was recently reported to be reduced head coverage of a newly introduced neutral liner. We therefore aimed to ascertain whether differences exist in articulating head coverage between the various neutral liners used in contemporary THR. A secondary aim was to utilize coverage measurements to develop a new liner coverage classification.Methods: The articulating head coverage of 25 modular neutral polyethylene liners used in 6 uncemented cup designs from 4 major manufacturers was evaluated. The measurements were performed in a metrology laboratory and a mathematical model was developed to calculate coverage of the articulating surfaces. Further, 1 “elevated rim” liner and 1 “face changing liner” were included to develop a new liner coverage classification.Results: The articulating head coverage among the studied liners ranged from 167.7° to 194.8°, corresponding to a variation of 27.1°. The variations with different cup and head sizes within each design were smaller (from 1.0° to 5.6°) than those between different designs. Each of the liner designs offered distinct coverage, even though they were all classified as neutral. Based on measurements, a set of descriptive parameters to discriminate different liners in terms of coverage was created.Conclusion: We showed that all neutral liners are not equal – instead, they clearly varied in terms of their actual coverage design. We suggest our set of descriptive parameters called “hemispheric coverage index values” be used in discriminating the differences in liner coverage.

The study of the reproduction characteristics of roses of the garden class Shrub, the defini-tion of the dependence of the hormonal determination of explant rhizogenesis on the con-centrations of phytohormones that are part of the nutrient medium, are relevant and has both scientific and practical interest. This study presents the results of studies of hormonal de-termination of rhizogenesis in explants of cultivars of roses of the garden class Shrub: Gärt-nerfreude, Lavender Dream, Pomponella, Red Cascade, Sommerabend cultivated in vitro on nutrient medium containing growth regulators. It has been established that of the nutrient medium modified by the addition of 0.2-1.0 mg/l α-naphthylacetic acid (α-NAA), the most effective was the medium with the content of α-NAA 0.5 mg/l, the content of macro- and microelements half of the Murashige and Skoog prescriptions, and a decrease in the sucrose content to 2.0%. On this medium, the frequency of rhizogenesis averaged 61.2% for the studied cultivars. Hormonal determination of rhizogenesis and efficiency of root formation in vitro in the Shrub rose regenerants depended on the genotype of the plant: cv. Lavender Dream (66.0%) and cv. Sommerabend (67.0%) had the highest rhizogenesis ability. The use of the universal growth regulator Humifield in combination with 0.5 mg/l α-NAA contribut-ed to an increase in the rooting rate of the studied rose cultivars up to 70.0-86.0%.

Published: October 2024

The 2006 Yogyakarta earthquake was caused by the tectonic movement of the Opak Fault, which is located near the Opak River. This research conducts microtremor data processing and analysis using the Horizontal Vertical Spectral Ratio (HVSR) method and the Inversion method to determine dominant frequency (fo), amplification (Ao), and shear wave velocity to a depth of 30 meters (Vs30) in Opak River area as an effort in earthquake disaster mitigation. The purpose of this research is to compare the Vs30 value of the inversion method using layer parameters according to Standard Penetration Test (SPT) data from previous research and layer parameters according to the number of lithologies. The result presents that the Vs30 values around Opak River are in the range of 183 - 301 m/s and belong to the stiff soil site classification.  The comparison shows that the Vs30 values in the two different layer parameters are both still in the stiff soil site classification and have a slight difference in Vs30 values. Thus, the use of microseismic data to determine the Vs30 value is a fast and efficient way to determine the subsurface geology of the study area.

Published: October 2024

The groundwater catchments of the Kolubarska Posavina are of significant importance because if some contamination affects the groundwater system, it is necessary to find a quality groundwater source for the water supply of Obrenovac Municipality. Reconstruction of sedimentary evolution plays a significant role in the investigation of groundwater catchment. In this study, the variation in sedimentary characteristics and sedimentary evolution/paleogeography were studied for Quaternary catchment identification in Kolubarska Posavina. The groundwater catchment of the Kolubarska Posavina can distinguished into two main parts. The western part of Kolubarska Posavina is identified as the Sava groundwater catchment, where the Sava alluvial plain and the (paleo) meanders of the Sava are located. The east part belongs to the Kolubara groundwater catchment, characterized by the remnants of the (macro) alluvial fan of Kolubara and the Kolubara floodplain. The Kolubara catchment is located eastwards from the older meander of the Sava River.

The impact of global and regional challenges on the decrease in tourist flows
Authors: Grudtsyn Nikolai A.
Published: October 2024

The article presents a comprehensive analysis of the impact of global and regional events on the dynamics of tourist flows. The primary reasons for the decrease in inbound tourist flows have been identified and categorized into three main groups: military-political class, economic class, and natural-technological class. Additionally, a hybrid class was identified, to which COVID-19 was assigned. The article is based on causal and comparative analysis, utilizing statistical data on tourist flows provided by the World Bank and UNWTO, as well as an assessment of similar patterns among countries worldwide. The main characteristics of tourist flows from 1995 to 2022 have been identified, pinpointing leaders among countries in increasing and decreasing the number of tourists per year. During the study, countries with similar patterns of tourist flow dynamics were identified. It was concluded that relying solely on quantitative analysis has limited applicability in identifying these patterns. Therefore, it is recommended that quantitative analysis be complemented with expert assessments for a more comprehensive understanding. The basic strategies for responding to the identified classes of causes were outlined. The research will benefit tourism professionals, governmental authorities, and researchers in socio-economic and political disciplines.
