The Evolution of Human Intelligence Throughout a Person’s Life – A Lifelong Journey

by | posted in: Archive, Natural sciences, Number 4, Volume 3 | 0

The evolution of human intelligence during a person’s lifetime is a process influenced by an interaction between biological development, genetics, environmental factors, and personal experiences. To comprehend the progression of intellectual growth, it is essential to explore the emergence, maturation, and sometimes, the decline of cognitive abilities, illustrating a complex interplay between genetic predispositions and environmental influences.

Discovery of Astatine by Horia Hulubei

by | posted in: Archive, Natural sciences, Number 3, Volume 3 | 0

The search for new chemical elements was a prominent scientific endeavor in the late 19th and early 20th centuries. This era saw the discovery of several elements such as radium, polonium, and radon by prominent scientists such as Marie Curie and Ernest Rutherford. Astatine was one of the missing elements from the periodic table, and its existence was predicted due to the periodicity of the elements, with iodine as its nearest stable neighbor. Scientists have sought to confirm its existence and properties. The discovery of astatine by Horia Hulubei and his collaborator Yvette Cauchois at the beginning of the 20th century is recognized by many scientists, although the authorship of this discovery was ignored by the Austrian radiochemist Friedrich Paneth, who was responsible for setting priorities in the discovery of new chemical elements. This article will delve into the historical background and scientific endeavors that led to the discovery of astatine by Horia Hulubei.

Epistemology of Loop Quantum Gravity in the Context of Canonical Quantum Gravity

by | posted in: Archive, Natural sciences, Number 2, Volume 3 | 0

In the quest to comprehend the fundamental nature of the universe, physicists have delved into the realms of quantum mechanics and general relativity. However, joining these two pillars of modern physics into a unified framework has been a longstanding challenge. Canonical Quantum Gravity, particularly in the form of Loop Quantum Gravity, emerges as a prominent contender in this endeavor. The epistemology of Loop Quantum Gravity encompasses a diverse range of principles and methodologies, including empirical foundations, mathematical rigor, background independence, and philosophical implications, all of which contribute to our understanding of the theory and its implications for our conception of the universe.

Cosmological Tests Based on General Relativity for Gravity

by | posted in: Archive, Natural sciences, Number 1, Volume 3 | 0

In the realm of cosmology, understanding the nature of gravity is crucial for unraveling the mysteries of the universe. The current cosmological models are built based on general relativity. The solutions of the specific equations, Friedmann-Lemaître-Robertson-Walker, allow to model the evolution of the universe starting from the Big Bang. Some of the parameters of the universe have been established by observations. Based on these, and other observational data, the models can be tested. Predictions include the initial abundance of chemical elements formed in a period of nucleosynthesis during the Big Bang period, the subsequent structure of the universe, cosmic background radiation, and so on.

Problems with String Theory in Quantum Gravity

by | posted in: Natural sciences, Number 4, Volume 2 | 0

String theory, a framework that aims to reconcile general relativity and quantum mechanics, holds a unique position in the field of quantum gravity. In quantum field theory, the main obstacle is the occurrence of the untreatable infinities in the interactions of the particles due to the possibility of arbitrary distances between the point particles. Strings, as extended objects, provide a better framework, which allows finite calculations. In the realm of theoretical physics, where theories often push the boundaries of human understanding, examining the epistemology of a theory becomes crucial. This article delves into the epistemological aspects of string theory’s role in our quest for a unified theory of quantum gravity, exploring the challenges it presents and the insights it offers.

The Psycho-Neural Connectivity

by | posted in: Archive, Natural sciences, Number 3, Volume 2 | 0

In this paper we follow the pathway sentient informational reality couples to our well-known mass/matter/energy world, in a well-integrated inter-dimensional process. Pure information in its pre-energetic aspect couples to subquantum (SQ) units and combinatorials of increasing complexity, able to transgress the ZPE (Zero-point energy) barrier between nonlocal information fields and local quantum processes, being stored and vehiculated by pre-quantum subtle energy variants. The link between these ontologically different domains is provided by the Compton-radius vortex configurations operating at the level of sub-quarks across all the periodic table of elements. Life as inherent condition of manifestation results as the conscious aspect of matter. The fundamental coupling mechanism between non-local and material regimes is supported both by compelling evidence supplied in bio-energetic physics and by recent mathematical proves.

Interactions between the brain, the biofields, and the physical

by | posted in: Archive, Natural sciences, Number 3, Volume 2 | 0

Before addressing the physical object of highest complexity in nature, the Brain, and its consciousness-related functional correlates, let’s remember some basic assumptions regarding biosystems as a whole. We expect to recognize such intricate cortico-informational integration mechanisms, as being the pinnacle of the representations we have been investigating. Obeying the holographic distribution principle which we have followed all along our analytic path, we have to keep in mind that in order to get an incremental improvement in the accuracy of our Brain-related understandings, its overall efficiency regulation must be associated with the biofield. This association is of an uttermost subtlety and complexity, since the biofield actively interacts with neurocybernetic processes, via Quantum and Subquantum connectivity.

Pandemia: Women and Policewomen

by | posted in: Archive, Natural sciences, Number 2, Volume 2 | 0

The COVID-19 pandemic has shocked the entire world, placing an additional burden on all people, regardless of gender, age, health condition, or social status. The pandemic also affects women’s decision to have children, pregnancy, childbirth circumstances, parental involvement, health status, and partnerships. The study addresses the challenges facing women, in particular the situation of female staff serving in the Police Force, who also have to cope with the increased workload resulting from the epidemic.

Drobeta Turnu Severin Heavy Water Plant: Construction

by | posted in: Archive, Natural sciences, Number 1, Volume 2 | 0

The heavy water plant was established under the name of Combinatul Chimic Drobeta, by Decree 400/16.11.1979, under the Inorganic Products Industrial Center (CIPA) Râmnicu Vâlcea. The thermo-electric plant for supplying the heavy water factory with steam was decided to be located in Halânga village, three kilometers from the factory. The process water required for the factory was brought from the Danube, and the hydrogen sulphide used in the process was produced in the plant, through a specific technology, and then compressed, liquefied and stored in special tanks. The works on the heavy water factory at Drobeta Turnu Severin started in 1979, based on a derogatory HCM. The equipment for the heavy water plant was purchased through the Industrial Center for Chemical and Refinery Equipment (CIUTCR). All equipment and facilities that transported hydrogen sulphide had to meet strict quality assurance conditions.
