In the constantly changing world of aerospace technology, innovations that enhance efficiency, safety, and performance are continually highlighted. A particularly revolutionary advancement is the creation and application of laser ignition systems in rocket engines. This technology, which substitutes traditional chemical ignition methods, marks the beginning of a new era in rocket propulsion, offering substantial benefits and future implications for space exploration. Numerous studies and experiments have been conducted globally in this field. The Laser Ignition System (LIS) is a promising technology that facilitates engine restarts and improves the efficiency of the ignition process.

The whole country has witnessed a massive change in the functioning at all spheres in the last two years due to Covid-19 pandemic. Education sector and, particularly, higher education in India had never gone through such a transformation which was totally unprepared for. Shifting to online teaching from face-to-face was a natural compulsion at all levels of education. Technical teachers also had to accept this challenge of engaging their students online. Even for the students, this unforeseen change to online learning was filled with several challenges; though some prospects could also be explored. The present study has been undertaken with some crucial objectives; viz. to identify the preference of the students for learning online over conventional learning; to explore the challenges faced in online learning; and to categorise the levels of motivation and confidence of students while studying on virtual platform. Teachers’ perception related to quality parameters in online learning was also observed. Though students were excited about using gadgets in learning, they found the traditional/conventional classes more interesting than those conducted online. Blended learning seemed to be the preferred mode of learning by the students. The teachers realised that apart from the cognitive aspect, the affective domain also matters even in higher education.

For the first time in the world, a universal generalized method for mono- and multifractals synthesis is proposed, which allows combining and reproducing almost all known artificial and semi-artificial methods of fractal synthesis on a single natural platform - Brownian point dynamics (BPD) in the field of N gravitational forces.

On the basis of the BPD method, a set of algorithms for the synthesis of fractal sets of a wide range of characteristics and properties, such as monofractal, multifractal, isotropic, anisotropic, rectangular, hexagonal, ring, single- and multi-loop, etc., has been developed.

The fractals synthesized by the BPD method enable the production of solid samples of these fractals with predetermined characteristics using modern 3D printing technologies and experimentally study their porosity, fractal dimensions, residual strength, aerodynamic and hydrodynamic drag, etc.

It is shown that the Brownian dynamics of a point in a field of N gravitational forces clearly demonstrates the generation of a fractal order by Brownian chaos with a cascade of discrete levels ordered by scaling, i.e., an important philosophical result of the demonstration of order from chaos. The influence of minimal values of N on the synthesis of linear, planar or volumetric multifractal sets is demonstrated.

In today’s fast-paced academic environment, effective knowledge-sharing tools play a crucial role in enhancing collaboration and productivity among students. This study investigates the impact of knowledge management (KM) tool design on knowledge recall and interpretation. Specifically, it evaluates the effectiveness of three communication modalities—Kanban boards, direct messaging, and face-to-face meetings—in facilitating knowledge transfer among university students. A study involving 20 participants was conducted, where web development tasks were assigned and completed using these three modalities. Participants’ recall and interpretation abilities were measured and analyzed using a Likert scale. The results indicate that Kanban boards and direct messaging significantly enhance knowledge retention, whereas face-to-face communication improves comprehension. These findings suggest that optimizing KM tool design according to task complexity can improve collaborative learning outcomes. Future research should explore advanced rating methods, broader participant demographics, and cross-disciplinary applications to refine KM tool effectiveness.

This article contains the design of a technical aid for stand-up support in patients with lower limb immobilization syndrome or with reduced mobility. The methodology applied in this article consisted initially in the definition of the design that complied with the necessary requirements for a correct stand up, the height and weight of the user were taken into account, then the pieces of the structure were designed, these pieces were designed independently in order to facilitate the final assembly of the technical aid, then the electronic circuit was designed using the proteus software, finally the final design and assembly was performed using the Autodesk Inventor Professional version 2021 software. We achieved the simulation and articulation of each of the parts that compose the structure of the technical aid to know how it works. The final result of the design will allow the ascent and descent of the patient in a controlled, safe and supervised way by the personnel in charge of the user.

According to Bertrand Russell- 'Science'

• "The facts of science, as they appeared to him [Heraclitus], fed the flame in his soul, and in its light, he saw into the depths of the world."

According to Francis Bacon -'The depths of the world'

• "The sciences that sway the imagination rather than the reason are principally three viz. These are: astrology, natural magic, and alchemy (…). Alchemy, may be compared to the man who told his sons/daughters that he had left them gold, buried somewhere in his vineyard/house; while they by digging the vineyard found no gold,
• But by turning up the mould about the roots of the vines procured a plenty vintage. For this reason the search and endeavours to make gold, have brought many useful inventions to light."
