The issues of studying vehicle tires, which belong to the category of complex ones, both theoretically and methodologically, play a significant role in an auto-technical expertise. At the same time, the theoretical basis of these studies is not sufficiently developed, and the related problems of forensic and methodolo…
Excitation of antiferromagnetic spin waves in HoFeO$_{3}$ crystal combined with a split ring resonator (SRR) is studied using terahertz (THz) electromagnetic pulses. The magnetic field in the vicinity of the SRR induced by the incident THz electric field component excites and the Faraday rotation of the polarization o…
En el presente trabajo se ha realizado un estudio del dano progresivo a impacto de dos biocomposites fabricados mediante el proceso de infusion de resina de origen renovable (SuperSap®) reforzada con dos fibras naturales bidireccionales: lino y yute, ambas con un gramaje de 300 g/m2. El estudio se realizo en dos etapa…
OBJECTIVE: The objective of this analysis is to examine the safety and pharmacokinetic profiles of eteplirsen, a PMO designed to skip exon 51 in patients with Duchenne Muscular Dystrophy (DMD). BACKGROUND: Duchenne Muscular Dystrophy is a degenerative X-linked genetic neuromuscular disorder with an incidence of 1 in 5…
A novel comb-shaped fluorinated poly(arylene ether) (cs-FPAE) was prepared from a difluoride monomer, 4-(2,6-difluorobenzoyl)diphenyl ether, with commercial 4,4′-(hexafluoroisopropylidene) diphenol by nucleophilic polycondensation reaction. The number-average molecular weight and polydispersities of cs-FPAE were in th…
Abstract In this work, a phenomenological Ginzburg‐Landau free‐energy model is developed for investigating structural and magnetic phase transitions in Heusler alloy Ni50Mn35In15. In particular, our model accounts for the inversion of the exchange interaction, which is coupled to the structural parameters of the cryst…
OBJECTIVE: We evaluated whether miRNAs are differentially regulated in the CSF of patients with ALS compared with CSF from normal controls. BACKGROUND: Amyotrophic lateral sclerosis (ALS) is an adult-onset neurodegenerative disease characterized by progressive loss of upper and lower motor neurons. There is no establi…
Στην παρούσα πτυχιακή παρασκευάστηκαν νανοσύνθετα υλικά TiO290-HALL10 και TiO280-HALL20 ώστε να εφαρµοστούν στην φωτοκαταλυτική αποδόµηση αερίων ρύπων. Τα νανοσύνθετα παρασκευάστηκαν µε τη µέθοδο διασποράς-επικάθισης του TiO2 και στους επιµήκεις κρυστάλλους του Αλλουσίτη.Η κρυσταλλική µορφή του TiO2 που συντέθηκε ήταν…
The strength of separators of roller bearings taking into account their operation, performance and design features is proposed to estimate using the load factor of separator, comprising the dynamic factor of external load, dynamic factor of load on separator by rollers, load factor of separator at misalignment, stress…
Purpose – The purpose of this paper is to investigate the degree of improvement in mechanical properties of aluminum alloy (AA6063) after processing with equal channel angular extrusion (ECAE) using four environmentally benign lubricants. Design/methodology/approach – Aluminum (Al) 6063 bar was annealed at 350°C for 1…
The burning rate of energetic materials depends on pressure and initial temperature. The relation between the burning rate and pressure has been well studied. However, the effect of the initial temperature on the burning rate has not been investigated quantitatively. In this study, the burning rates of 1H-tetrazole, c…
Atomic force microscopy (AFM) shows that Langmuir–Blodgett (LB) deposition of dissimilar metal stearates (MSt, M = Co, Zn, Cd) on templates of Co-stearate (Co-T) and Cd-stearate (Cd-T) results in self-assembly of MSts into nanocrystalline grains having clear and consistent morphological habits. The grains are better f…
Microscopic properties of atoms and molecules that participate on a given chemical experiment are the main focus when theoretical treatments are made. In many cases these approaches lead to a very complex construction using, in general, stochastic processes to describe the behavior of the system. In this paper, we con…
Mathematical modeling of spatial vibrations of hopper on freight-car trucks of the 18-100 model and new trucks of the 18-1711 model, produced by OJSC “Azovmash” (Ukraine) was carried out. The study was conducted to justify and correct the accepted engineering solutions in creating the truck of the18-1711 model. The pr…
A photonic bandgap (PBG) extension of surface-disordered 3D photonic crystals (PCs) based on the TiO2 inverse opal (TiO2-IO) architecture has been demonstrated. By using a liquid phase deposition (LPD) process based on the controlled hydrolysis of ammonium hexafluorotitanate and boric acid, an extra layer of TiO2 nano…
OBJECTIVE: To demonstrate delivery of GDNF to brain regions affected in Parkinson’s (PD) by novel nano-vesicles (V-SmartTM) targeted to dopaminergic neurons for treatment of PD. BACKGROUND: Neurotrophins like GDNF have good potential as therapeutic agents in PD. However, neurotrophins do not penetrate the BBB and a ta…
Results of experimental investigations and calculations of jet emulsion and pneumatic atomizers for spraying aviation fuels are surveyed. On the basis of the data obtained atomizers using various sources of spraying high- and lowpressure air were designed and tested. A new optical express-method to investigate fuel-ai…
Abstract The complex (Me2AsS2)3Ga (1) attracted water molecules that slowly and completely hydrolyzed it. The product was the dinuclear gallium compound (Me2AsS2)2Ga–S–Ga(S2AsMe2)2(2) as2·0.75H2O, which was structurally characterized with X‐ray crystallography (P212121,R1= 0.0321,wR2= 0.0622). Compound2shows an approx…
OBJECTIVE:This study measures the variability of REM without atonia (RWA), the electrophysiological hallmark of REM sleep behaviour disorder (RBD), across two consecutive nights of polysomnography (PSG) in a cohort of patients with Parkinson’s disease (PD). BACKGROUND: RBD is observed in more than half of all patients…
OBJECTIVE: To evaluate effects of siponimod (BAF312) and propranolol co-administration on heart rate (HR), blood pressure (BP), PR interval and incidence of bradyarrythmias. BACKGROUND: Siponimod is a selective sphingosine-1-phosphate (S1P-1,5) receptor modulator under development for secondary progressive multiple sc…
