Problems with String Theory in Quantum Gravity

by Nicolae Sfetcu | 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 Adventures of Pinocchio – Education

by Nicolae Sfetcu | posted in: Archive, Number 4, Social sciences, Volume 2 | 0

Carlo Collodi, a positive representative of the Italian petty bourgeoisie of the late nineteenth century, presented in the novel the moral virtues of a secularized rural Italy. He inserts moralistic exhortations and reflections in the novel, to give up the waste of time to dedicate to study, hard work and savings. Pinocchio’s negative experiences and the good advice of the Fairy guide him in the end on the right path, after he understood the importance of study and work, thus fulfilling his desire to be transformed into a child.

Humanism, Becoming and the Demiurge in The Adventures of Pinocchio

by Nicolae Sfetcu | posted in: Archive, Number 3, Recenzii cărți, Volume 2 | 0

The common thread of Pinocchio’s story is his desire to become a human being. Unlike some creators who approached the adventures of Pinocchio in the context of posthumanism the transhumanism embraces technological progress while strongly defending human rights and individual choice. Pinocchio is aware of his incompleteness: he seeks during the story to become “a real boy.” Human consciousness can refer to things that we do not perceive directly. Pinocchio is a “child” without a mother, created by his father to fill his loneliness. He highlights the current problem of the relationship between man and his creation, out of control.

The impact of DoS (Denial of Service) cyberattacks on a Local Area Network (LAN)

by Nicolae Sfetcu | posted in: Media | 0

In this paper I will highlight a modus operandi of hackers launching Denial of Service (DoS) cyberattacks. I will theoretically show how CAM Overflow and TCP SYN Flood attacks can be performed, using Kali Linux, a Linux distribution used by cyber criminals to launch MitM (Man-in-the-Middle) attacks, DoS attacks, observing traffic in a computer network, etc. Hackers can affect the functioning of devices on an organization’s local network (server, router, switch, etc.) by sending thousands of packets per second to … Read More

Models of Emotional Intelligence in Research and Education

by Nicolae Sfetcu | posted in: Archive, Number 3, Social sciences, Volume 2 | 0

The emotional intelligence models have helped to develop different tools for construct assessment. Each theoretical paradigm conceptualizes emotional intelligence from one of two perspectives: ability or mixed model. Ability models consider emotional intelligence as a pure form of mental ability and therefore as pure intelligence. Mixed models of emotional intelligence combine mental capacity with personality traits. The trait models of emotional intelligence refer to the individual perceptions of their own emotional abilities. Cognitive learning involves placing new information into existing frameworks and modes of understanding.

Identity and Artificial Intelligence in The Adventures of Pinocchio

by Nicolae Sfetcu | posted in: Archive, Formal sciences, Number 2, Volume 2 | 0

Pinocchio is, above all, what he is not. His identity is often played to the limit, imagined by himself and everyone he meets along the way. Pinocchio is the name of life that is simultaneously inorganic, human and animal. For this reason, it is the possible name of a radical desertion: to identify at the same time with oneself and with someone other than oneself. One question that can be deduced from The Adventures of Pinocchio is whether such an intelligent machine would like to become “human”? In fact, before Pinocchio becomes a real boy, he does everything that real boys do, including the disobedience to their parents.

Drobeta Turnu Severin Heavy Water Plant: Construction

by Nicolae Sfetcu | 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.
