“…But one should be noted that for tissue engineering (as well as for all implanted materials), it is permissible to use 100% of synthesized compounds. The active ingredients isolated from amber, which can be purified and approved by pharmacology, can be the basis for their subsequent productions and implementation in blood vessels implant structure [44][45][46].…”

The amber nano fibres are bio-active composites which could be applied in three-dimensional printing. The idea of using the amber for creating a new 3D printing material, including technological composition of the innovative amber nano and micro fibres is based on the hypothesis that organic compounds of succinite have an effective impact on living cells, including reparative, stimulating, for sedative effects as well protective properties from electro-magnetic field. To produce amber nano fibres, bioactive components were used that were isolated from the succinite and tested (in vitro) in the scientific laboratories. Three-dimensional printing is an emerging technology, which has been initially used to design and generate three-dimensional structures mainly for transplantation therapies. This process, which can be used for a variety of polymers, is becoming an increasingly essential component of biotechnological advancements. This article discusses the foundations of this technology, namely the processes used in conventional three-dimensional printing; it also discusses tissue engineering, a discipline of which new implementations of this technology are used as bio printing. The shortcomings of tissue engineering are addressed, including the failure of existing technology to manufacture nanofiber-based constructs used in blood vessels, cartilage, artery valves, tendon, cardiac muscle valves, muscle, and cornea. From this need for nanofiber processing, electrospinning is proposed as a possible roadmap for imminent tissue engineering threedimensional printing technologies, and finally, the latest integration of this technology with three-dimensional printing is addressed, highlighting the existing shortcomings in maintaining mandatory nano resolutions.

“…A GIS is one of the most effective tools for presenting and analysing statistical and geospatial data utilising spatial analysis techniques such as (Tupenaite et al, 2017). Other technological advancement can also give huge impact on real estate industry over the globe, for example, negatively charged particles of amber can be used in mask, which helps repel Covid viruses, which also have negative charge (Ļašenko et al, 2016 andGaidukovs et al, 2016). In India, where the people cannot be vaccinated in a short period of time due to huge population, this may be a viable option for real estate and other industries in the present environment.…”

The world economy seems to be experiencing one of the most severe downturns in recent memory. The latest pandemic has had a detrimental effect on the economies of several nations, including India. The International Monetary Fund forecast India’s growth rate at 1.9 % for fiscal year 2021, down from 5.8 % previously. This poses a significant challenge to the Indian economy. The resumption of work was complicated by the workers’ surprising return to the employers from underground. Developers struggled to locate enough job-creating jobs due to the labour market severe constraints. The populace is burdened by the great pestilence that threatens the nation. Indian real estate, which was still emerging from the implications of demonetization (November 2016) and other changes, was jolted by this pandemic, with building development halted and real estate transactions paused. Indian real estate should plan itself for a post-COVID-19 environment and be prepared to take several new and technology-driven moves to get back on track. The secondary data research methodology is used in this paper and the aim of the research is to discuss the pre-pandemic real estate market and the effect of COVID-19 on the Indian real estate market. Additionally, it discusses the risks and prospects confronting various real estate industry participants.

“…Nowadays, one of the main engineering challenges is to develop and introduce in the mass production efficient reinforcement material. An example is: innovative reinforcing composite fibre metal-crystalpolymer with protective properties from the electromagnetic field [8], [9]. Short fibres may be the main or the secondary reinforcement (in combination with rebars) bearing the bending moments and the shear stresses.…”

Concrete reinforced by short steel fibres is typical brittle matrix composite, in which fibres are impeding cracks growth, such way increasing material’s tensile strength. The use of steel fibre reinforced concrete (SFRC) in structures with high physical and mechanical characteristics makes possible to reduce their weight and cost, to simplify their production technology, to reduce or eliminate reinforcement labour, at the same time increasing reliability and durability. Randomly distributed discontinuous fibres are bridging the crack’s flanks providing material’s “ductility”- like non-linear behaviour at cracking stage. The current study is focused on one formulation of a specific type of concrete matrix with added fibres and without fibres. Concrete cubes and prisms without fibres and having in every situation the same content of 60 mm long fibres were fabricated. Cubes (100×100×100 mm) were tested in compression and beams (100×100×400 mm prisms) were tested under four-point bending (4PBT). Fracture process (crack growth) in the material was modelled, based on experimental results (part of experimental data was used). Finite element method (FEM) using the ANSYS program analysis were realized modelling stress distributions in the broken beams with the goal to predict fracture process. Model’s prediction was validated.
