For study the energy output law of cylindrical charge with shell induced by different input energies, four different black powder masses were selected to ignite the main charge. Fragmentation degree of the shell was qualitatively analyzed by the area of holes on the witness plate and the recover...

Laser ignition mechanism enhances the safety of explosive applications. However, optical sensitisation of the energetic materials is required for their optical absorption. In this research, explosive Cyclotrimethylene Trinitramine (RDX) was doped with gold nanoparticles during recrystallisation ...

In the framework of the joint Russian – Italian collaboration on the development of the IGNITOR project some preliminary estimates of the risk factors that may be occurring during the realization of the project were recently carried out.A distinctive feature of the IGNITOR project is the fact t...

A safety analysis study has been applied to the Ignitor machine. Deterministic evaluations of radioactive environmental releases have been performed. The preliminary radiological impact analysis for the normal operation and the main accidental sequences of Ignitor, in case of its localization in...

Recent research efforts in the domain of fire debris analysis have been mainly oriented towards the development of innovative analytical procedures and chemometric approaches for the detection and classification of ignitable liquids in fire specimens according to the ASTM E1618. However, less at...

The Radio-Frequency (RF) Corona Ignition System is an innovative and promising technology able to produce multiple streamers to ignite the fuel throughout the combustion chamber. This system, compared to a conventional spark ignition system, involves wider initial combustion volumes and allows t...

This paper examines the effect of igniter type (glow plug vs. spark igniter) and number of igniters on the dynamics of vented combustion under both initially quiescent and fan-induced turbulent conditions. These experiments are a subset of many series of tests performed in a 120 m3 large scale v...

The tokamak Ignitor is one of the main long-term projects involving scientific cooperation between Russian Federation and Italian Republic. Currently, negotiations are underway to develop the Ignitor Technical Design Project with on-site placement at site of the experimental bench complex "Tokam...

This study evaluates the ignition performance of a new miniaturised igniter that operates based on microwave resonance phenomenon. This igniter, named Flat Panel Igniter (FPI), consists of a flat ceramic panel with a metal strip inlay on the top surface acting as a resonance cavity. The FPI and ...

The ignition technology is the key of in-situ combustion, which determines the start of in-situ combustion. This paper proposes a droppable solid fuel igniter for in-situ combustion based on the principle of traditional igniter, which aims to design a droppable solid fuel igniter and demonstrate...

Background: Epoetin delta, unlike recombinant erythropoietins, is produced in a human cell line and therefore has a human-type glycosylation profile.Objectives: The pharmacokinetics of epoetin delta were examined in 2 studies in healthy volunteers and 2 studies in patients with chronic kidney di...

Background & Aims: Transforming growth factor-β (TGF-β) has been implicated in the pathogenesis of liver disease. TGF-β is involved in liver regeneration and in the fibrotic and cirrhotic transformation with hepatitis viral infection. Hepatitis delta virus (HDV) infection causes fulminant hep...

A theoretical analysis is performed on the nonlinear ordinary differential equations that govern the dynamics of a reaction mechanism of zymogen activation. The reaction consists of a primary non-observable zymogen activation reaction that it is coupled to an indicator (observable) reaction. The...

Background and aimsCirculating soluble urokinase plasminogen activator receptor (suPAR) is a marker of immune activation associated with atherosclerosis. Whether suPAR levels are associated with prevalent peripheral arterial disease (PAD) and its adverse outcomes remains unknown and is the aim o...

ObjectivesThe formation of biofilms on titanium dental implants is one of the main causes of failure of these devices. Streptococci are considered early colonizers that alter local environment favouring growing conditions for other colonizers. Chlorhexidine (CHX) is so far the most effective ant...

The free-radical copolymerization of SO2 with phenyl, p-t-butylphenyl, p-nitrophenyl and 1-naphthyl acrylates and the terpolymerization of those monomers with 1-heptene were studied. The maximum content of sulphonyl monomeric units in copolymers varies from 13 to 24% depending on the induction a...

The radical copolymerizations of p-cresyl acrylate, p-chlorophenyl acrylate, p-bromophenyl acrylate and m-nitrophenyl acrylate with methyl methacrylate have been studied. The reactivity ratios for these systems have been determined for copolymerization at 60° in benzene; they were calculated by...

The use of aryl acrylates in the Baylis-Hillman reaction is reported. In contrast to their alkyl counterparts these acrylates react very rapidly with aldehydes, often yielding cyclic products arising from reaction of the initial adduct with a second molecule of aldehyde.

Highly porous polymers (polyHIPEs) incorporating activated esters have been prepared by photopolymerisation of high internal phase emulsions (HIPEs) containing pentafluorophenyl acrylate (PFPA) in the monomer phase. The resulting materials have nominal porosity of 80% and a well-defined, interco...

Key features of the β-isocupreidine (β-ICD)-catalyzed asymmetric Baylis–Hillman reaction of aldehydes with 1,1,1,3,3,3-hexafluoroisopropyl acrylate (HFIPA) are presented. In addition, an improved method using azeotropically dried β-ICD is described.
