Restoration of obliterated vehicle identification number using magneto optical imaging: case study

Ahmed Sulaiman Ali Alkhanbouli — 2025-03-08

Serial numbers serve as distinctive identifiers for various items, yet they can be intentionally removed by individuals engaged in criminal endeavours such as theft or the illicit use of stolen goods, obscuring their origin and ownership. Nowadays, numerous techniques exist for restoring erased serial numbers. Although chemical and electrochemical methods are well-known among investigators for their limitations, the technique of magneto-optical imaging (MOI) is frequently perceived as a novel approach, despite its widespread use in the field for over two decades globally. It stands out as a prominent technique utilized in forensic laboratories for the restoration of erased serial numbers engraved on metal surfaces. This experiment illustrates the functioning of the MOI technique for the restoration of VINs and exemplifies the outcomes through practical demonstrations.

An insurer's perspective on climate change: from risk to opportunity

Latif Zeynalli — 2025-03-08

Green insurance involves insurance products created by insurers to support environmental sustainability and minimize the risks linked to environmental damage. It is a vital strategy for promoting sustainable development. As global environmental issues worsen and there's a greater emphasis on sustainable development, green insurance will become increasingly important for businesses, organizations, and governments in facing these challenges. It's important to note that green insurance will remain relevant as public awareness of environmental issues grows and these issues pose genuine threats to businesses and organizations. The main goal of this research is to introduce green insurance products, evaluate their significance in the insurance market, and summarize the key points identified during the development and implementation of these new products. The research extensively used theoretical research approaches such as abstraction, analysis, synthesis, and deduction. A drawback of the study is that insurers in the current insurance market do not widely apply the green insurance mechanism.

Migration abilities of radionuclides in various types of ecosystems

A. I. Alieva — 2025-03-08

This article is devoted to the study of the migration ability of radionuclides along the soil profile in various types of soils in different ecosystems. A method has been developed for assessing the intensity of migration of soil radionuclides using the constructed regression equations and the value of λ, which is constant and depends on the type of soil in ecosystems. The constructed regression equations make it possible to estimate the intensity of radionuclide migration along the soil profile. The highest intensity of radionuclide migration along the soil profile is observed in soils that are light in granulometric composition.

Studying the properties of nickel germanosilicides using the Romanov spectrum method and ellipsometric methods

Bobojonov Komilzhon Abdusharipovich — 2025-03-08

Nickel german silicides formed on a bulk single-crystal n-(Si_1-x-Ge_x) (111) substrate are being investigated. Monogermanosilicide Ni(Ge_1-x-Si_x) and silicide NiSi phases are formed sequentially with increasing annealing temperature from 200^oC to 900^oC on the n-Ge (110) substrate. The results obtained on the Romanov shift of Raman-“OCEAN INSIGHT”, graphs of layered monolayers of super lattices were plotted, studied using the Origin-Phyton software, layers, period, as well as thickness from 1 nm to 1000 nm and the band gap of nano-layers 0.03-0.1 eV were determined. The thickness of monolayers of super lattices 25, 75, 95, 375, 1050 nm was determined using a SER 850 SEN research 4.0 spectral ellipsometer manufactured by SENTECH Instruments GmbH.
