The paper reports on the life and works of Fred Vlès (1885-1944) and Paul Reiss (1901-1944), and Charles Laville (1877-1959) who worked in a similar field. Vlès was the founder of the first institute of biophysics in France at the University of Strasbourg, and Reiss was his pupil and associate. They worked in the time of 1910 to 1944 on the acid-alkaline balance and the reduction-oxidation (redox) potentials of the body fluids and tissues and their influence on the proteins and colloids of the “terrain”, along the line...s given by the “milieu interne” (internal environment) or homeostasis concept by Claude Bernard. Vlès and Reiss were also electrobiologists and were some of the first scientists to investigate the physiological effects of electrical grounding where also the work of Charles Laville is relevant. In the conclusion we link this historical narrative to contemporary research.Read more

Since time immemorial, Indigenous communities have always perceived the landscape as a complex web of living, physical, and spiritual things. These communities have always relied on their Indigenous knowledge systems (IKS), emphasizing ancestral burial grounds, mountains, caves, rivers, pools, forests, monuments, and other cultural diacritics as symbols of place identity. In addition, myriad metaphors like taboos, legends, tales, folklore, myths, proverbs, stories, and practices, also constituted an integral part of Indigenous cultural and natu...re connections. This heritage was constantly imagined and configured to cement human-nature relations. However, the advent of colonialism severely violated this status quo, thereby causing deep environmental, political, and social crises. Through imposing a hegemonic scientific paradigm, knowledge compartmentalization, and capitalist aggrandizing practices, the original harmonious human-nature praxis premised on IKS was disrupted. To this day, the exclusionary colonial legacy and poisoned ‘sense of place’ remains our greatest threat to climate and environmental stability. Thus, this paper advocates for the recentralization of IKS as a valid way of knowing with already inbuilt human and natural disaster management solutions. By pivoting Rozvi narratives premised on five mountains, namely; Manyanga in Bubi district, Mavangwe, MunwewaMwari and Bepe in Buhera district, and Mutikwiri in Maungwe near Rusape town, all situated in former Butua/Guruuswa regions of Zimbabwe as case studies, the power of ancient wisdom as a holistic epistemic approach towards sustainable human-nature relations is explicated.Read more

The finite Markov chain to which there correspond the qualities of the conformational dynamics of the K-Ras4B proteins in the catalytic reaction is written. The corresponding Markov-Sates models are studied. The properties of the K-Ras4B processes Markov chain allow one to define a new two-state MSM for the analytical description of the final-state transition. The time evolution of the eigenvalue corresponding to the final-state transition in the Galerkin description is written. The tools for the analytical calculations of the relative error ...are therefore prepared. New analytical formulations of the time evolution of the eigenvalue corresponding to the final-state transition are newly written from the experimental data and form the properties of the lag time in shaping the discretization error. The features of the discretization error are newly studied. A comparison with the experimental data is proposed.Read more

Semantic segmentation is the most significant deep learning technology. At present, automatic assisted driving (Autopilot) is widely used in real-time driving, but if there is a deviation in object detection in real vehicles, it can easily lead to misjudgment. Turning and even crashing can be quite dangerous. This paper seeks to propose a model for this problem to increase the accuracy of discrimination and improve security. It proposes a Convolutional Neural Network (CNN)+ Holistically-Nested Edge Detection (HED) combined with Spatial Pyr...amid Pooling (SPP). Traditionally, CNN is used to detect the shape of objects, and the edge may be ignored. Therefore, adding HED increases the robustness of the edge, and finally adds SPP to obtain modules of different sizes, and strengthen the detection of undetected objects. The research results are trained in the CityScapes street view data set. The accuracy of Class mIoU for small objects reaches 77.51%, and Category mIoU for large objects reaches 89.95%.Read more

The textile sector has great relevance in the Brazilian socioeconomic context, generating large volumes of effluents of varied composition, with dyes being one of the most worrying contaminants due to their characteristics of high solubility, harmfulness and low degradability. Among them the Reafix Yellow B8G (ARB8G) dye has an azo nature, harmful to organisms in the aquatic environment. According to Brazilian laws, it is recommended to dispose of waste through incineration or landfill, due to its resistance to biodegradation. One of the method...s for treating effluents is the adsorption of contaminants using materials with adsorption capacity, such as residue from the burning of biomass in boilers (ash). The general objective of this work was to evaluate the adsorption kinetics by contact time of the ARB8G dye by boiler ash. The test was based on mixing the adsorbent material with a dye solution at 75 mg.L-1, at constant temperature and stirring at different time intervals. To quantify the amount of adsorbed dye, the UV-Vis spectrometry method was used. The kinetic test indicated an equilibrium time of 30 minutes, with 100% removal under the tested conditions. From this result and considering that boiler residue is an underutilized and low-cost material, it is concluded that this substance has significant potential to be applied as an alternative material for the treatment of effluents containing dyes.Read more

The use of polycarboxylate ether superplasticizer PCE in the preparation of mortars and concretes influences the hydration kinetics and the amount of total heat released. This leads to a modification of certain properties of the mortar, namely workability, calorimetry and mechanical resistance. In this study two ether polycarboxylate superplasticizers with different chemical structures were used; they were incorporated at different dosages into a standardized cement-based mortar. The objective of this work is to study the effectiveness of these... superplasticizers and to select the most compatible product with cement and the most suitable for use according to the climates of the country. The impact of superplasticizers on fresh cement was studied by measuring the Marsh cone flow time and calorimetric measurement. In the hardened state, the mechanical properties were provided by measuring the compressive strength. The results show that low dosages of ether polycarboxylate superplasticizer promote grain hydration and produce more heat. On the other hand, high dosages delay the contact of the cement grains with the mixing water and cause a reduction in the final heat released and a delay in setting. The ether polycarboxylate superplasticizer with high carboxylic density gives the best mechanical resistance compressive at 7 and 28 days.Read more

The aim of the study is to develop a methodology for a professional-business game for the development of a cadet leader in professional training courses (L-1B) of the tactical level of military education on the example of teaching the discipline “Combat use of military communication systems and complexes”. After all, the most important prerequisite for the combat potential of the Armed Forces of Ukraine is a comprehensively trained officer-leader, his consciousness, knowledge, skills, military-technical qualifications, creative and ...innovative activity, developed emotional and volitional sphere of the psyche, beliefs, motivation, and ideals. The article summarizes the research on the state of development of a cadet leader in Ukraine. In the context of a full-scale war, there is a need to strengthen the development of the personality of a cadet leader (a future officer of the tactical level of military education). Today’s cadet-leader is tomorrow’s officer-leader, capable of integrating knowledge and solving complex problems in new or unfamiliar environments with incomplete or limited information, being a leader and authority for the personnel. Therefore, the scientific and practical task arises to consider aspects of the development of the personality of a cadet leader and to modernize the process of his development, for example, in the courses of professional military education L-1B (tactical level of military education) in terms of the disciplines of the Department of Combat Use of Communication Units. The periodization of cadets’ adaptation to the new educational space and service activities is considered, the optimal period of leader growth is determined, and the mechanism itself is proposed. The article separately identifies the key tasks for the selection of academic staff and admission to the educational process. The methodology of the professional and business game for the development of a cadet leader in professional training courses (L-1B) of the tactical level of military education is developed on the example of teaching the discipline “Combat use of military communication systems and complexes”. The scientific novelty of the work is the improved educational process of training and development of a cadet leader in professional training courses (L-1B) of the tactical level of military education by reformatting group classes in the traditional format into a professional business game for the positions of officers with the introduction of typical and atypical (force majeure) training tasks for cadets in everyday activities in new or unfamiliar environments in the presence of incomplete or limited information.Read more

By measurements on single nanocrystals of indium antimonide in the interelectrode nanogap of a scanning probe microscope, current-voltage characteristics with quasiperiodic current pulsations, are explained in the model of Bloch oscillations in a perfect nanocrystal, and individual sharp peaks - conductivity resonances, explained in the model of quantum-size limitation of the wave process of electron transport in a deep potential hole. The mutual influence of radiation from two statistical ensembles of nanocrystals from the same batch was exper...imentally studied and established. It is assumed that this radiation is entangled photons. It is proposed to use nanocrystals in nanoelectronics as a single-electron memristor, a single-photon bolometer, and a source of microwave radiation.Read more
