Partial defects of dental rows results of the questionnaire and clinical assessment of the condition of removable prostheses

The process of adaptation of patients to a removable denture construction is a complex and long-term physiological test for the human body, based on neuro-reflex processes in new conditions of functioning. The summary data of the survey are presented in the table

PEO-b-PCL-b-PMOXA Triblock Copolymers: From Synthesis to Microscale Polymersomes with Asymmetric Membrane

We report a new family of amphiphilic ABC triblock copolymers: poly(ethylene oxide)-block-polycaprolactone-block-poly(2-methy1-2-oxazoline) (PEO-b-PCL-b-PMOXA). The synthesis is free of toxic reagents, well-controlled and results in polymers with D-M < 1.25 and PMOXA length up to 25 units (2 kDa). We compare the self assembly of PEO-b-PCL-b-PMOXA with PEO-b-PCL depending on PCL length and hydrophilic weight fraction (f) using the film rehydration method. Polymers self-assemble into different microscale structures, including polymersomes, which were studied by laser scanning microscopy. We proved the asymmetry of polymersome membrane by two independent methods, which confirmed the presence of a longer PEO block and the absence of a shorter PMOXA block on the outer surface of polymersomes

Complex Self-Assembly Behavior of Bis-hydrophilic PEO-b-PCL-b-PMOXA Triblock Copolymers in Aqueous Solution

We report aqueous self-assembly of linear amphiphilic triblock copolymers poly(ethylene oxide)-block-polycaprolactone-block-poly(2-methyl-2-oxazoline) (PEO-b-PCL-b-PMOXA) and their PEO-b-PCL precursors with different PCL and PMOXA block lengths using three preparation methods: film rehydration, solvent evaporation, and cosolvent. For PEO-b-PCL, the self-assembled structures were ordinary spherical particles and polymersomes. For PEO-b-PCL-b-PMOXA, we observed polymersomes with asymmetric membrane, cloud-like aggregates, elongated particles, Y-shaped elongated particles, and 3D networks. All structures were of micrometer size and characterized using laser scanning microscopy (LSM). 3D networks were also characterized using z-stack confocal LSM, transmission electron microscopy (TEM), and cryogenic TEM. We demonstrated that film rehydration method results in pseudoequilibrium structures, whereas structures formed using solvent evaporation and cosolvent methods are under kinetic control. We showed how kinetically controlled structures can be transformed into pseudoequilibrium morphologies

Preparation of the procedure of virtual organization development in construction

The use of virtual structures in the area of CAD may have an impact on the design labour coefficient and on the works cost reduction. When developing and further functioning of virtual structures in organization, there are a number of issues related to the employees search and employment, work with CAD, with staff, payment for activities, acquisition and storage of information, reporting, interaction between the virtual team members, etc. The full activity of project organizations, both within the large and independent companies, requires for new procedural developments based on the information systems. The procedure of virtual structures development and implementation in organization is proposed to resolve this issue

Stark effect or coverage dependence? Disentangling the EC-SEIRAS vibrational shift of sulfate on Au(111)

Infrared spectroscopy is a widely employed analytical tool in (electrochemical) surface science as the spectra contain a wealth of information about the interaction of interfacial adsorbates with their environment. Separating and quantifying individual contributions, for example, of co-adsorbates, the substrate or electric field effects, on the overall spectral response, however, is often non-trivial as the various interactions manifest themselves in similar spectral behavior. Here, we present an experimental approach to differentiate between and quantify potential-induced coverage dependence and field-related Stark effects observed in a sulfate band shift of 93.5 ± 1.5 cm−1/V in electrochemical infrared spectra of the showcase sulfate/Au(111) interface. In combination with a simple linear model equation used to describe the potential-induced peak shift of the sulfate stretch vibration, we determine the coverage dependence contribution to be 15.6 ± 1.2 cm−1/θSO and the Stark effect to amount to 75.6 ± 2.7 cm−1/V. Our work provides a novel route to gain fundamental insight into interfacial adsorbate interactions in electrochemical surface science.J.H.K.P. and K.F.D. gratefully acknowledge financial support by the Max Planck Graduate Center with the Johannes Gutenberg University Mainz (MPGC).

Despite the rapid development of dentistry and advances in the prevention of diseases of the maxillofacial region, implantology, and the treatment of dental diseases, the number of patients who need prosthetics with removable orthopedic structures of dentures remains high, and only increases with age, due to the increasing rate of aging. society of the planet (M.Yu.

Among the reasons for the high demand for orthopedic treatment with removable dentures, the leading position is still held by insufficient sanitation of the oral cavity, untimely access of patients to the dentist. In addition, an important role is played by the problem of imperfection of materials and technologies used for the manufacture of dentures, leading to a deterioration in the condition of the dentition
