Introduction to Digital Policy Studies
Authors: Ndzendze Bhaso
Published: June 2022

All over the world, governments, intergovernmental organisations, citizens and businesses are simultaneously driving, coping with and grasping the reality of digitalisation. They have promulgated new legislation, published plans, and put out strategies to pursue their brand of accelerated or perpetual development with the aid of electronic equipment and software for communications and cyber-physical execution. These entities have also used technologies to regulate, circumvent and/or contest one another. In the wake of these realities, new concepts have been introduced in the literature and the practitioner’s manuals and the citizen’s everyday lexicon. From agriculture to banking, culture, diplomacy, electric grids, finance, governance, human rights, international trade, and journalism, technologies are pushing the frontier of what was previously possible. With new capabilities and the proliferation of technologies such as artificial intelligence, big data, blockchain, and quantum computing, the process is receiving a significant jolt. Importantly, however, the benefits (convenient and efficient access to goods, services, information and ideas) are not even or universal. Neither are the side effects (climate change, exclusion, and e-waste, among others). Geographical, economic, and other realities reinforce old divides and give rise to new ones. But there are also instances of the gap being closed.
Technology and welfare
Authors: O’Riordan Alexander C
Published: June 2022

The relationship between technology and individual welfare is not well understood, and as we progress into a future in which technology invades almost every aspect of life, the importance of this relationship must be recognised and an improved understanding reached. In this study, we attempt to lay a foundation for such an understanding. Using an approach based on Sen’s theory of Capabilities and the South African National Income Dynamic Survey (NIDS), it estimates the effects of the ownership of technological assets on self-reported measures of well-being, both subjective and objective. Any empirical analysis of this relationship needs to control for several confounding factors. The estimation procedure employed is based on a dynamic panel approach, one that is capable of controlling for individual effects, as well as potential sources of endogeneity such as reverse causality. The results indicate that there is a statistically significant relationship between changes in the composition and value of one’s technological asset portfolio and measures of social and economic well-being. Specifically, they show that increased ownership of technological assets improves one’s overall life satisfaction and health status, but has little effect on one’s positivity about the future. This study has found evidence that technology can improve lives when controlling for confounders such as increased wealth and status. Future work can improve upon this by better understanding the dynamics of this relationship, and disaggregating further by type of technology.
Textualism and the Indian Canons of Statutory Construction
Authors: Skibine Alex
Published: June 2022

When interpreting statutes enacted for the benefit or regulation of Indians or construing treaties signed with Indian nations, courts are supposed to apply any of five specific canons of construction relating to Indian Affairs. Through examining the modern line of Supreme Court cases involving statutory or treaty interpretation relating to Indian nations, this Article demonstrates that the Court has generally been faithful in applying canons relating to treaty interpretation or abrogation. The Court has also respected the canon requiring unequivocal expression of congressional intent before finding an abrogation of tribal sovereign immunity. However, there are two other canons that the Court almost never applies. One, the tribal sovereignty canon, requires clear intent to interfere with tribal sovereign rights; the other, the Indian ambiguity canon, requires statutes to be construed liberally with ambiguities resolved to the benefit of Indians. After reviewing the possible reasons why textualist jurists might be opposed to the use of substantive canons, this Article makes two arguments to remedy any reluctance to using the tribal sovereignty and Indian ambiguity canons. First, these canons have constitutional roots, and as such, even textualists on the Court should not be reluctant to use them. Second, the more established canon concerning abrogation of tribal sovereign immunity should also extend to statutes interfering with tribal sovereign rights. There are no normative reasons to treat abrogation of sovereign immunity differently than other statutory interference with tribal sovereignty.
Eksistensi Hukum Internasional terhadap Hukum Nasional dalam Pembuatan Perjanjian Internasional
Authors: Laitupa Salma , Dewi Kartika Eka , Yasser Arafat J. Fadly
Published: June 2022

The existence of international law has been accepted, recognized and respected as a legal norm that governs the international community. The rules of international law can be accepted and adapted in the national law of countries. The mechanisms and procedures used by each country to apply international law at the national level are not uniform. One of the main reasons is because they consider this a part of state sovereignty.

As a system of norms, international law is based on the highest norms that function as an assessor of the validity of international agreements made between countries. The highest norms in international law are called peremptory norms (jus cogens). Therefore, an international agreement cannot be valid when an international agreement conflicts with the highest norms in international law

Published: June 2022

Due to its nutritional and medicinal properties, Laetiporus sulphureus has gained increased interest worldwide. The polysaccharides of L. sulphureus exhibit potentials as therapeutic agents for many chronic diseases. The optimal conditions for extraction of L. sulphureus polysaccharides, preliminary characterization, and in vitro antioxidant activity were investigated in the present study. The optimal extraction conditions included a temperature of 83°C for 3 h, and the ratio of material to liquid of 1:23 with an yield of 1.45%, which was close to the predicted value (1.36%). In vitro antioxidant activity assays showed that L. sulphureus polysaccharides effectively scavenged the 2,2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid), 1,1-diphenyl-2-picrylhydrazyl, and hydroxyl radicals, and it also exhibited the reducing power using K3Fe (CN)6. The polysaccharides of L. sulphureus were mainly composed of glucose, galactose, xylose, fucose, and galactosamine hydrochloride, and with mass percentages of 49.6%, 27.9%, 12.7%, 8.20%, and 1.6%, respectively. These results suggested that L. sulphureus could be used as a potential source of natural antioxidants.

Published: June 2022

The present study has examined the effect of procyanidin A1 on insulin resistance and oxidative stress in palmitic acid treated HepG2 cells. The HepG2 cells were pretreated with procyanidin A1 and then with palmitic acid. The cell viability and the levels of catalase, superoxide dismutase, glutathione peroxidase, and reactive oxygen were used to assess oxidative stress. Treatment with palmitic acid significantly reduced cell viability that was alleviated by cotreatment with procyanidin A1. In addition, procyanidin A1 restored the palmitic acid induced insulin resistance and oxidative stress in the HepG2 cells. Furthermore, inactivation of P38 MAPK and JNK signaling pathways was closely associated with the procyanidin A1-regulated resistance and oxidative stress in palmitic acid treated HepG2 cells. In conclusion, procyanidin A1 inhibits insulin resistance and oxidative stress in palmitic acid treated HepG2 cells by regulating the P38 MAPK and JNK signaling pathways.
Bilobalide Improves Steroid-Induced Avascular Necrosis of the Femoral Head through PI3K/AKT Pathway
Authors: Zhou Bin , Zhou Guangfu , Zhang Wenzhou , Tang Benshun , Wang Guochuan , Zhang Xiaolu
Published: June 2022

Steroid-induced avascular necrosis of the femoral head is a metabolic disease that results from the use of glucocorticoid drugs, leading to impaired blood supply to the femoral head and death of bone cells and altered bone marrow composition, which in turn lead to structural changes, collapse of the femoral head, and articular dysfunction. It is a challenging disorder to manage due to frequent collapse of the femoral head and dysfunction of the hip joint often requiring joint arthroplasty surgery. Therefore, there is a critical need to develop effective strategies to prevent and treat this condition. Bilobalide, an intermediate metabolite of ginkgolide, is known to inhibit apoptosis, protects damaged cells, and protects the brain from injury. However, the role of bilobalide in steroid-induced avascular necrosis of the femoral head is poorly understood. In this study, we investigated the role of bilobalide in steroid-induced avascular necrosis of the femoral head in rats. Our data show that bilobalide reduced femoral head inflammation and oxidative stress in steroid-induced avascular necrosis of the femoral head in rats. Bilobalide reduced the apoptosis of femoral head cells in steroid-induced avascular necrosis of the femoral head in rats. In addition, bilobalide improved bone tissue injury in steroid-induced avascular necrosis of the femoral head in rats. Mechanically, bilobalide improved steroid-induced avascular necrosis of the femoral head through PI3K/AKT pathway. We therefore suggest that bilobalide may serve as a promising drug for steroid-induced avascular necrosis of the femoral head.

Published: June 2022

The motivations with which students choose the higher programme to follow have a high impact on their academic performance throughout the programme and on the dropout rate. The type of motivation (intrinsic or extrinsic) that leads them to choose the programme area is very important in their resilience in the face of difficulties they may encounter during the programme. It is also important to attract students to a particular area of higher education. In Portugal (in line with other countries), the demand for higher education programmes in the field of Electrical Engineering has been decreasing among students applying for higher education. This decrease occurs despite the area have high employability. On the contrary, the demand for Mechanical Engineering and Electromechanical Engineering programmes has been growing. Given this, it is important to try to understand the motivations that lead students to apply for programmes in the field of Electrical Engineering. For a better understanding of the reasons that differentiate the demand for programmes in the electrical area and the mechanical area, it was considered important to study whether there are relevant differences between the motivation profile for choosing the programmes between Electrical Engineering and Electromechanical Engineering Thus, this study aimed to understand and analyse the motivations that led students from a Portuguese Polytechnic higher education institution to choose the field of Electrical Engineering or of Electromechanical Engineering. To this end, a questionnaire survey was used to collect the students’ perceptions about why they chose the programme. The results show that students highly value the fact that it is a broadband area, with high employability and a wide variety of potential professional activities. The comparison between the programmes shows that the area of mechanics is a factor that motivates students to apply for the Electromechanical Engineering. The results obtained help to understand the motivation profile of students who choose the field of Electrical Engineering and of Electromechanical Engineering, potentially contributing for the higher education institutions to promote actions with a view to enhancing the attractiveness of Electrical Engineering area.

Published: June 2022

Microneedles (MNs) are a means to break the protective skin barrier in a minimally invasive way. By creating temporary micropores, they make biologically active agents available in the skin layers. Propolis (PRP) is a gum resin with a complex chemical composition, produced by bees Apis mellifera L. and showing several therapeutic properties (i.e., antibacterial, antiviral, antifungal, anti-inflammatory, healing, and immunomodulatory properties). The administration of PRP extracts by conventional routes has some disadvantages, such as running off over the skin in liquid or emulsion form. When taken orally, the extracts have a strong and unpleasant taste. The aim of this work was to fabricate and characterize microneedles containing polyvinyl alcohol, polyvinylpyrrolidone, poloxamer P407, and an ethanolic or glycolic extract of PRP. Also, the obtained structures were microscopically and mechanically characterized. The results of the mechanical analysis showed that formulations containing 3% of P407 presented the highest compression values in a hard surface, which was also confirmed by the height and base values of the morphological analysis and by the microscopy images. It was possible to design MNs and select the best formulations for future tests. MNs containing an ethanolic extract of PRP showed to be better structured than MNs containing a glycolic extract of PRP. The MNs obtained in these studies proved to be a promising platform for the topical application of PRP.

Lemongrass is an herbal plant with the Latin name Andropogon nardus L. In Indonesia alone, lemongrass is widely cultivated. Not only as a flavoring in cooking, citronella is also a plant that produces atsiri oils. The chemical components contained in citronella are quite complex, but the most important are citronella and geraniol, as determinants of odor intensity, fragrance, and the value of the price of citronella oil. Not only the benefits of citronella can be taken, the waste from citronella can also be utilized. One area that produces citronella is Pendalian Village, Rokan IV Koto District, Rokan Hulu Regency, Riau. The owner of the garden directly carries out the production process and markets it to collectors, but since the COVID-19 pandemic, the price of citronella oil has dropped drastically and is difficult to market. The data collection method is carried out with partner site analysis and surveys. With this service, it is hoped that the owners of the lemongrass gardens in Pendalian Village can overcome the processing and marketing of citronella oil production, so that it can trigger the economic development of Pendalian Village.

On inland waterways, the most perspective vessels are the tanker/platform type, carrying the main (bulk) cargo in the hull and the return (dry) on the platform equipped on an open deck. The article presents a general mathematical model and an algorithm for selecting elements and characteristics of the specified type of vessels, allowing them to be optimized in various operating conditions with specified initial data. The carried out extensive test calculations, systematized and presented in the form of graphical dependencies, show the effect of the stroke speed on the coefficient of the overall completeness of the hull at various backloading volumes, the efficiency in the form of the relative profit of a combined vessel compared to a "clean" tanker from the share of backloading and the ratio of freight rates for dry and liquid cargo. The low dependence of the relative profit on the length of the lines of operation is also shown.

The article carried out a qualitative risk assessment taking into account the developed scale "Probability / frequency and using "The Classifier of consequences" for several options for the offshore fields development. "The Consequence Category Classifier" takes into account environmental, financial, life, health and time risk criteria affecting construction and operation. The risk analysis was carried out taking into account the existing regulatory documentation and based on the analysis of the causes of the occurrence of factors that determine the outcomes of accidents, taking into account all the features of the cases under consideration for the life cycle stages: Design work, Production and testing, Use (operation). The degree of agreement in the performance of the experts group work was made based on the calculation of the Kendall rank coefficient. Subcategories were determined simultaneously for all the considered field development facilities according to the results of the performed calculations in risk categories. a Risk register was compiled based on the developed scale "Probability/Frequency" and the developed "Classifier of Consequence Categories". The risk register included 72 risks. The “Risk Index” was determined as a result of calculations. As a result, based on the results of a qualitative risk assessment, a "Risk Matrix" was developed based on the methodology presented in the Register Rules. In this case, the Alarp model or the principle of reasonable sufficiency was used. This risk assessment allows you to determine: the degree of the risk importance, prioritize different categories of risks, choose the best option with the lowest "Risk Index".

The unique geographic location of the European part of Russia, which determines its transit potential, presents significant opportunities for the effective development of the transport complex, since it is here that a kind of international transport crossroads of two corridors: "East-West" and "North-South" is located. For inland water transport, the North-South International Transport Corridor (ITC) is of the greatest interest, through which trade is carried out between European countries and Iran, Pakistan, and Iraq. In addition, it is predicted to attract cargo flows from the countries of the Middle East and India. At the same time, the volume of trade between countries within the North-South corridor in 2019 reached more than 200 thousand in twenty-foot equivalent (TEU). According to forecasts for 2035, it can grow to 400,000 TEUs. Part of the cargo traffic can go through Russia in transit from the Caspian Sea to Europe in river-sea vessels. At the same time, the current state of the key artery of the European part of Russia - the Volga River does not provide regular movement of such due to the lack of depths of the ship's passage, which has a negative impact on the economy of transportation and the competitiveness of inland water transport. As a result, the cargo flows traditional for river transport go to road and rail transport. At the same time, studies of recent years indicate that auto and railway lines located parallel to inland waterways are overloaded. As a result, we have an increase in emissions of harmful gases into the atmosphere, an increase in the share of logistics costs in the cost of transportation, and an increase in the cost of maintaining and repairing roads.

The issues of development and creation of a multi-purpose stand based on the 2СH 10.5/13 engine are considered. The main areas of experimental research at this stand are: utilization of exhaust gas heat, ways to reduce emissions of harmful substances from engine exhaust gases, optimization of engine system parameters, the use of various fuels in internal combustion engines, including water-fuel emulsions and biofuels, control of the working process in the cylinder and torque measurement. It is emphasized that these directions do not exhaust the possibilities of the stand. The measures for the modernization of the engine and stand systems are considered: air supply and gas outlet, fuel and cooling. It is shown that in order to control the parameters of the stand, a measuring complex is needed that allows continuously measuring a large number of parameters, performing their processing, displaying, archiving and transferring to a computer that controls the operation of the stand.
Peculiarities of numerical simulation of river flows in analyzing the consequences of ship accidents

Published: June 2022

The consequence of accidents with ships may be the ingress of cargo and fuel into the riverbed. To predict the consequences of such accidents in some cases (the presence of specially protected areas, the proximity of water intake facilities, etc.), it is necessary to take into account the hydromorphological features of the riverbed. One of the stages of such accounting is numerical modeling of river flow. In this paper, the authors analyzed the features of such modeling. For this purpose, a research scheme was drawn up, a mathematical apparatus was selected, a river section was selected, on the example of which the authors studied the features of the modeling process. In addition, based on a comparison of different approaches to modeling the turbulence process, it is concluded that it is preferable for sites with the presence of backwater tanks, stagnant zones and breakaway flows to model not the dissipation of turbulent energy, but the specific kinetic energy of turbulence. It reproduces the flow structure more correctly, speeds up the calculation process and gives better convergence of solutions. The results obtained in this work can be used to analyze the influence of river flow characteristics on the spread of pollution in ship accidents.
Determination of the ship's pitching parameters during an operational voyage
Authors: Umrikhin Viktor P.
Published: June 2022

In this article, it is proposed to use a hardware and software complex created on the basis of microcontroller technology to record and visualize the parameters of the ship's pitching during an operational voyage. The ability to continuously record the parameters of the keel and side pitching of the vessel in various weather conditions and the changing loading of the vessel allows you to quickly monitor the stability parameters and improve the safety of navigation in difficult weather conditions of stormy navigation.

The track recorded in MS EXCEL with the pitching parameters and the current time allows you to compare the recording time with the effect of various hydrometeorological conditions, taking into account both wind and wave effects on the vessel, including from hydrometeorological objects located at a considerable distance from the current position of the vessel. These data make it possible to carry out a harmonic analysis of pitching, to obtain the frequency spectrum, phase-frequency characteristics, proper pitching period and amplitude-frequency characteristics of the vessel.

Published: June 2022

Currently, classification societies provide additional signs and verbal characteristics to indicate a variety of measures to ensure environmental safety of the ship. This system of signs indicates the need to demonstrate the level of environmental safety of the ship and the desire to meet the objectives of environmental labeling. The authors propose a direction for improving the environmental labeling of ships by conducting a comprehensive assessment of the ship's impact on the environment using environmental indicators. The proposed comprehensive assessment should be based on environmental criteria covering the entire life cycle of the ship – design, construction, operation, recycling. It is shown that it is necessary to establish the level of environmental safety of the ship based on these criteria, taking into account the degree of influence (importance) of each.
