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…
OBJECTIVE: To present the CSF1R screening in 218 PPMS patients and to report the clinical features of a case of Hereditary Diffuse Leukoencephalopathy with Spheroids (HDLS) with a novel CSF1R mutation, who was initially diagnosed as PPMS. BACKGROUND: HDLS is a devastating hereditary, white matter (WM) disorder with he…
OBJECTIVE: A unique case report on extrapontine myelinolysis (EPM) presenting as parkinsonism. BACKGROUND: EPM is a rare complication (10% of osmotic demyelination cases) of rapid correction of hyponatremia associated with diverse presentations and outcomes. This is a unique case of EPM due to severe parkinsonism, unr…
Si riporta la misura della percentuale di carbonio moderno di n. 7 campioni di polimeri organici fornite dalla ditta Granarolo spa, per la determinazione del contenuto bio delle plastiche utilizzate nel confezionamento dei prodotti alimentari.
La mise en forme de matériaux fonctionnels et leur texturation contrôlée à toutes les échelles sont des conditions sine qua non pour l’amélioration des systèmes existants. Ce projet de thèse consiste en la création de structures solides complexes en utilisant des méthodes interdisciplinaires telles que la chimie sol-g…
Molybdenum cofactor (Moco) biosynthesis is an ancient, ubiquitous, and highly conserved pathway leading to the biochemical activation of molybdenum. ModE enhances the transcription of molybdenum-dependent enzymes like DMSO reductase or nitrate reductase A and also of the molybdenum cofactor biosynthesis operon moaABCD…
BACKGROUND PML is a rare complication of natalizumab therapy. The diagnosis relies mainly on the detection of the JCV in CSF and on MRI. Large T2 hyperintense and T1 hypointense lesions are typically observed. Punctuate gadolinium-enhancement in vicinity of the T2 hyperintense lesions, is observed in 40% of cases, in…
OBJECTIVE: 1) to measure intracellular and extracellular sodium concentration (ISC and ESC) in MS patients using sodium MRI at 7T; 2) to investigate the associations between total sodium concentration (TSC), ISC and ESC and measures of lesion and brain volume; 3) to assess the clinical significance of ISC and ESC. BAC…
OBJECTIVE:To evaluate the prognostic role of CSF Neurofilament Light Chain (NFL) levels in predicting the conversion to definite MS in patients at first clinical episode suggestive of MS BACKGROUND:Increased concentrations of CSF NFL levels have been reported in patients with MS since the earliest stage of the disease…
Climate change is one of the biggest challenges facing the world. The largest contributor to climate change is the greenhouse gas CO2, which is released through anthropogenic activities such as burning of fossil fuel and agricultural waste. To find solutions to mitigate climate change, research has been proposed to re…
OBJECTIVE: To compare PIB retention in early- and late-onset temporal-variant frontotemporal dementia (tvFTD), Alzheimer's disease (AD), and controls. BACKGROUND: The amyloid tracer, Pittsburgh compound B (PIB), identifies amyloid-β (Aβ) deposition in patients with AD. Frontotemporal dementia (FTD) patients typically…
