EGALITATEA: RESPINGEREA DIFERENȚELOR IRELEVANTE
Authors: OLARU Bogdan
Published: February 2024

Moral equality, the idea that people have equal moral value, is often justified by highlighting a key capacity or property that all people possess (like rationality or the capacity to conceive and pursue a life plan or anything else). This view is met with the objection that every human capacity is subject to empirical variability – therefore, we are not actually equal. Some have rejected this objection and emphasized the typological equality of people, that is, the idea that we are all members of the same natural type or species. Belonging to the same type would preclude any request to take account of empirically proven differences. Typological equality will allegedly encapsulate the very notion of moral equality along with the moral requirement of equal treatment. I will show that this strategy conflates equality with identity. A natural type is defined or constructed by reference to a characteristic and distinct property. The requirement to treat each human being equally derives from one’s typological identity and the normative claim that attaches moral value to the property that differentiates the natural type. Such inference makes moral equality a second-order moral principle. There is, however, a more fundamental meaning in which we could express human equality. It is the compelling force of the requirement to reject some differences as morally irrelevant that gives equality such a major significance for moral life. In the first part of this paper, I argue for the separation between fundamental and derivative equality, the latter being inferred from the idea of shared identity. The second part illustrates this first more fundamental sense of equality through the debate on the human races around 1790 by Herder and Blumenbach.
MARY WOLLSTONECRAFT’S PROJECT FOR A REFORM OF THE MINDS
Authors: SEGALERBA Gianluigi
Published: February 2024

In my investigation, I analyse aspects of Mary Wollstonecraft’s thought regarding the traditional education of women, her programme of education, the question of women’s rights, and the condition of women. I moreover investigate Mary Wollstonecraft’s proposal of new theological foundations for religious belief. Mary Wollstonecraft aims to propose a revolution in female manners. Her revolution is a revolution of minds: she aims to reach a complete reform in the education and the formation of individuals, in general, and of women, in particular. Mary Wollstonecraft’s revolution is a revolution for the spiritual independence of individuals. To reach the condition of independence, traditional education ought to be criticised and refused since traditional education is the system through which women are transformed into dependent entities. Power over oneself, liberation from passions, and autonomy of judgment are the main targets of Mary Wollstonecraft’s programme of education. The correct foundation of the individual ought to be reason. Mary Wollstonecraft proves to be a deeply religious thinker: she steadily connects the promotion of the dignity of mankind to a new way of worship of Deity. The centrality of reason profoundly influences her theological assumptions: Mary Wollstonecraft refuses all forms of reverence based on blind submission to God. The main texts of my inquiry are A Vindication of the Rights of Woman and A Vindication of the Rights of Men.

Aim: The aim of this study was to explore the geographical disparities in CVD incidence across the Attica region, over a 20-year period. Material and Methods: The 10-year and the 20-year CVD incidence data were provided by the ATTICA study, which was conducted during 2002-2022 in 3042 individuals living in Attica region. After excluding those lacking complete locality information and those lost in the 10-year and the 20-year follow-up, data for 1935 and 1902 individuals respectively, were used for the current analysis. CVD incidence rates at municipality level were mapped and hot spot analysis was implemented to recognize statistically significant spatial clusters in Attica region. Results: Mapping CVD incidence rates revealed a notable rise during the 20 years in most municipalities. The rise in female-specific CVD incidence appeared primarily in suburban areas, while a significant rise in male-specific CVD incidence was noticed in urban areas. Statistically significant spatial clusters of high values were indicated in the most urbanized municipalities of the study area, whereas clusters of low values were noticed in the more distant rural municipalities, which maintained lower CVD incidence rates during the monitoring period. Conclusions: A spatial heterogeneity of the sex-specific 20-year CVD incidence rate was observed in the Attica region of Greece.

Authors: Samprokatsidis Georgios , Antza Christina , Frangou Despoina , Kotsis Vasilios
Published: February 2024

Familial Hypercholesterolemia (FH), a commonly missed disorder in a patient with abnormalities in lipid metabolism is described as a heritable disorder presenting elevated LDL cholesterol and lipid deposition in various tissues. This contributes to the early development of manifestations of atherosclerotic disease with the preterm occurrence of severe cardiovascular events. Apparently, decision-making is a strenuous effort and many individuals are underdiagnosed. FH affects LDL receptor and its function plays a critical role in the mechanism of many therapeutic modalities, thus alternative pathways must also be considered. This review addresses the main options of care in individuals with familial hypercholesterolemia along with unconventional drugs like mipomersen, inclisiran, lomitapide, gamcabene, and ANGLT3 inhibitors which have yielded important results for disease management.

Published: February 2024

This paper shows a global analysis of fixed jacket platform infrastructures. Analysis of transportation, verticalization of the launch truss, assembly of the jacket, load out of the jacket and launch modules overboard are carried out. The indication of the most suitable location for drilling wells will be based on the presence of areas favorable to the accumulation of gas and/or oil, which are identified based on a combination of geological and geophysical methods. Drilling activities can also be carried out by installing a modular rig on its structure. They are designed to accommodate all drilling equipment, material storage, staff accommodation, as well as all the facilities necessary for well production. In Brazil, the recent discoveries of natural gas reserves in the Santos, São Paulo, practically tripled the country's reserves. Therefore, the need for knowledge in this area and an approach to the construction methodology of off-shore platforms become essential. This work demonstrates the importance of improving the executive techniques of an off-shore platform, aiming for quality at a lower cost.

Published: February 2024

The present study aimed to verify the occurrence of Leptospira spp., georeferencing of outbreaks, risk factors and zootechnical profile of goats in the Regions of Chapadinha and Itapecuru-Mirim - MA. 1260 blood serum samples were collected from goats from 126 properties distributed in 22 municipalities. The samples were subjected to the Microscopic Serum Agglutination (SAM) technique. A socio-epidemiological questionnaire was applied to determine the zootechnical profile of goat farming and the associated risk factors. There was a prevalence of 93% of 630 animals and 100% of 126 herds. The serovars responsible for the highest frequencies were Sentot with 36.03% (227/630), Autumnalis 35.56% (224/630), Andamana 26.67% (168/630), Pomona 25.87% (163/630), Hardjo 24.60% (155/630), Hebdomadis 21.59% (136/630) and Shermani with 20.79% (131/630). In most of the reacting herds, the system was extensive in continuous grazing, in contact with flooded areas and other species, in addition to not having technical assistance. The results obtained indicate the high frequency of Leptospirosis, where goat farming reflects subsistence.
Statistical analysis of self-affinity of energy dispatch in power generation in the Northeast region of Brazil
Authors: Limeira Giorgio Onofre , Mergulhão Henrique Gomes , Lima André Telles da Cunha , Lima Ivan Costa da Cunha
Published: February 2024

In this article, we study the fractal dynamics in time series of energy generation in the Northeast region of Brazil, considering a database used by the National Electric System Operator referring to semi-hourly information on the generation of various energy sources. Applying the DFA technique between the years 2020 and 2022, it was found that the dispatch of solar energy fluctuated in all years from superdiffusive behavior in the short term to persistent in the long term, whereas wind generation in all years varied from superdiffusive short-term to long-term subdiffusive. In all observation periods, there was a repeatability of the dispatch behavior of wind and solar sources, which can be explained by the fact that these sources always maintain a standard of availability for the energy matrix. When analyzing the behavior of solar generation, a greater predictability of energy availability was found, which can therefore be considered as a more viable source to make up for the lack of hydraulic energy. This analysis is based on historical time series numbers, not considering the costs of each energy source, environmental license situations, among other factors.
Physical-chemical composition of bean accesses Phaseolus vulgaris L. produced in the brazilian Semiarid
Authors: Rêgo Lúcia Virginia Castor do , Mata Mario Eduardo Rangel Moreira Cavalcanti
Published: February 2024

Beans are one of the most consumed and produced foods in Brazil, however, uncertified seeds and grains, that is, “creole” accessions, are neglected in the development of research that allows knowledge of their proximate composition and nutritional potential. The objective of this work was to evaluate and statistically compare the proximate composition of seeds when raw in three accessions of creole beans (black, white and big blue), produced in the Mesoregion of Borborema, state of Paraíba, Brazil, a region known as having great plant agrobiodiversity. The raw seeds were crushed, then evaluated for water content on a wet basis (w.b.), ash, protein, lipid and carbohydrate content. The results were subjected to analysis of variance, and the means were compared using the Tukey test (p<0.05). The accessions showed statistically significant differences between them in terms of proximate composition, however, the averages evaluated were compatible with those found for bean seeds in other trials.
Study concerning quenching and partitioning as a path for optimizing retained austenite content in a potential TRIP steel
Authors: Pereira Carlinéia Marciana dos Santos , Silva Fabricio Martins da , Flausino Paula Cibely Alves , Silva Nayara Aparecida Neres da
Published: February 2024

Steels assisted by the TRIP effect have aroused the interest of several studies, particularly driven by the automotive sector and its needs. The multiphase microstructure of these steels, consisting of ferrite, martensite, bainite and retained austenite, is responsible for achieving excellent properties that allow the production of increasingly thinner sheets, reducing the weight of the parts without losing their original characteristics. The present study sought to produce a stable microstructure and quantify the volumetric fraction of austenite retained at the end of quenching and partitioning processing and identify the distinct structures present in the materials produced. The heat treatment cycles were determined to verify the routes with the highest percentage of retained austenite using the Koistinen Marburguer equation (1959). Microstructural characterization and mechanical behavior were conducted by optical microscopy (OM), X-ray diffraction (XRD) and hardness tests. It was found that higher quenching and partitioning temperatures produce a higher fraction of retained austenite. However, the carbon content of austenite is of fundamental importance in the microstructural stability of the steel produced.

Hệ số FCR từ 8,0 - 9,8. Sau 12 - 16 tháng, cá đạt cỡ 4,5 - 7,5 kg/con, tỷ lệ sống 65 - 75%. Việc quản lý môi trường và phòng trị bệnh vẫn chưa được chú trọng do nhiều nguyên nhân. Cá được tiêu thụ chủ yếu tại địa phương và một phần tại các thành phố lân cận. Nghiên cứu đã tiến hành phân tích SWOT về hiện trạng nghề nuôi cá bớp và đề xuất 5 nhóm giải pháp liên quan đến khoa học công nghệ, thị trường, quy hoạch/chính sách, quản lý môi trường và bệnh, và đào tạo khuyến ngư nhằm phát triển bền vững nghề nuôi cá bớp tại Kiên Giang.

Ảnh hưởng của chitosan lên sự sinh trưởng của lan Mokara nuôi cấy mô
Authors: Phạm Thị Minh Thu  , Nguyễn Ngọc Thiên Trang  , Huỳnh Kim Đỉnh
Published: February 2024

Mokara là loài lan đẹp, đa dạng về màu sắc, ưa khí hậu nóng, dai sức và dễ trồng. Vì vậy, có những thời điểm mokara được trồng và nhân giống rộng rãi, đặc biệt bằng phương pháp nuôi cấy mô. Tuy nhiên, gần đây cây cấy mô mokara ít được phát triển vì tốc độ phát triển chậm kể cả trong giai đoạn nhân giống in vitro và chăm sóc in vivo. Trong nghiên cứu này, chitosan được thêm vào môi trường nhân giống nhằm cải thiện tốc độ sinh trưởng của chồi lan, từ đó giảm bớt thời gian nuôi cấy mô. Chitosan tách chiết từ vỏ tôm và mai mực với 3 khoảng phân tử lượng (Mw <10, 30-50 và 80-100 kDa, kí hiệu Mw10, Mw30 và Mw80) và 3 độ deacetyl (72-75, 82-85 và 92-95%, kí hiệu D70, D80 và D90) đã được khảo sát với tiêu chí kích thích chồi lan tăng trưởng về chiều cao. Kết quả cho thấy chitosan tôm, Mw30, D80 sử dụng ở nồng độ 20 ppm là phù hợp cho kích thích tạo chồi và kéo dài chồi. Như vậy, nghiên cứu đã minh hoạ cho tác dụng kích thích sinh trưởng lên thực vật in vitro nói chung của chitosan và mở ra một hướng ứng dụng cho đối tượng lan mokara nói riêng.

Metals and Minerals
Authors: Crowson Phillip
Published: February 2024

Global political and economic developments shape both the demand for minerals and primary metals and their supply. Overall, demand has moved broadly in step with economic activity over the past 30 years. Notwithstanding the collapse of the Soviet Union and Eastern Bloc countries, demand grew more rapidly in the second half of the period than the first. The performance of individual products within this general trend largely reflects the specific nature of their main end uses. The geographic center of demand has shifted away from the mature industrial economies of North America, Western Europe, and Japan toward the newly industrializing countries of the Pacific Rim, China, and India. Mine production rose with demand, but not always in precise step. New capacity was required not just to meet demand, even where that was static, but also to offset the continuing effects of ore depletion. There were also changes in the location of production in response to geopolitical forces, the depletion of ore reserves, and the changing economics of extraction and processing. The number of mines contracted, especially during the 1990s, and the scale of mining operations was increased in order to achieve the requisite cost savings. Prices fluctuated in response to changing balances between supply and demand, trending downward from the early 1970s until the early 2000s. Most products witnessed at least one sharp price spike during the period, usually with continuing repercussions. Prices picked up from 2003, but generally not back to their earlier peak in real terms. Profitability varied according to the products concerned. In many years the average rates of return on capital employed have been insufficient to cover the risks involved.

This Paper mainly covers the period from the late 1970s to the present day, but with references back to the early 1970s in order to set the scene for many subsequent trends. The mineral industry and its associated primary processing industries are integral components of the global economy. Mineral prices and profitability depend on the interaction between the demand for mineral products and their supply, which are in turn critically dependent on global conditions. Any realistic analysis of the industry has to place it within the context of these global economic and political conditions, and sketch out how the main global influences, both malignant and benign, have altered over the period. The next section of the paper therefore describes the context within which the mineral industries
The Rise of Sustainability
Authors: MacDonald Alistair , Gibson Ginger
Published: February 2024

The risks associated with, geographic locations of, and engagement strategies required by exploration companies have shifted in the last 25 years, largely in response to changing public attitudes and governance approaches. A mixture of growing global environmental consciousness, the rise of international civil society networks, and economic liberalization and government deregulation in the developing world have all played key roles in altering the environment for mineral exploration. Three fundamental tenets of a positive climate for exploration have been altered: access to land, ease and speed of permitting, and the right to mine deposits after discovery. This paper identifies the importance of new stakeholders, including nongovernmental organizations, international financial institutions, and community activist networks; new governance approaches, such as self-regulation, the use of international standards and co-management, and new monitoring and engagement techniques, such as environmental and social impact assessment, thirdparty monitoring, and prior informed consent. The traditional relationship focus between states and corporations has been replaced by constantly evolving relationships among corporations, governments, civil society, and affected communities. Exploration companies, particularly junior companies, must use available tools—early community engagement strategies and available guidance documents from industry associations among them—to adapt themselves to this new focus.
Mine Design and Costs, and Their Impact on Exploration Targets
Authors: Rendu Jean-michel , Santti Scott , Hansen Phil , White Dan
Published: February 2024

Over the last 20 years, utilization of mineral resources has improved dramatically following changes in mine technology and operating practices, resulting in lower costs and increased productivity. Improved deposit modeling methods, better understanding of geotechnical constraints, optimized mine designs, automated production scheduling, new methods of ore control, progress in the design of blasting, loading, and haulage equipment, and changes in operating practices—all contributed to better utilization of manpower and equipment and significantly lowered production costs. Safety and environmental concerns are an integral part of mine design, construction, operation, and closure. But to reap the benefits of these changes, early understanding of the geologic, geochemical, mineralogical, metallurgical, geotechnical, and hydrological properties of mineralized deposits and surrounding areas is increasingly critical.

Assumptions concerning what makes a viable exploration target must always be challenged. Cutoff grades can be lowered. Large, low-grade deposits, including halos around old mines, are viable exploration targets, and small underground deposits still remain economical to mine. Deeper deposits can be considered. Difficult geotechnical environments can be mined safely. Greater care must be taken in the early definition of the type, quality, and quantity of geologic information, which must be collected before a decision is made to open a new mine. Ore control practices are critical to the success of most operations and require ongoing contributions from mine geologists. Successful closure is dependent on attention being given to geologic input throughout the life of the project. Open communications between geologists, mining engineers, metallurgists, environmental engineers, and operators are more important than ever.
