НА ОБЛОМКАХ КОНСЕНСУСНЫХ СТРАТЕГИЙ XX ВЕКА. К ВОПРОСУ О ТЕОРЕТИЧЕСКИХ ОСНОВАНИЯХ КРИЗИСА СОЛИДАРИЗМА

The first decades of the XXI century have shown that mankind has once again suffered disappointment in optimistic forecasts, promising peace and harmony to the people. Increasingly, symptoms are manifested that contradict solidarity: increased distrust, centrifugal tendencies,  the desire to leave unions and associations, the growth of violence, the spread of the threat of terrorism – all this indicates the growth of destructive trends in the modern world. In this situation, reliance on force (whether hard or soft) seems much more preferable than trying to reach consensus. It is not surprising, therefore, that almost all theoretical models that focus on the rationale for consensus strategies, have faced a serious crisis of legitimacy if not lost their impact on real policies. The article analyzes the base theoretical foundations of the solidarity concepts of the second half of the twentieth century, identifies their vulnerable positions, which served as a target for criticism in modern political science and political philosophy, and traces the possible vectors of their transformation

Nanomechanical humidity detection through porous alumina cantilevers

Abstract We present here the behavior of the resonance frequency of porous anodic alumina cantilever arrays during water vapor adsorption and emphasize their possible use in the micromechanical sensing of humidity levels at least in the range of 10-22%. The sensitivity of porous anodic aluminium oxide cantilevers (Δf/Δm) and the humidity sensitivity equal about 56 Hz/pg and about 100 Hz/%, respectively. The approach presented here for the design of anodic alumina cantilever arrays by the combination of anodic oxidation and photolithography enables easy control over porosity, surface area, geometric and mechanical characteristics of the cantilever arrays for micromechanical sensing. 133

Unveiling point defects in titania mesocrystals: a combined EPR and XPS study

Titania mesocrystals, prepared using a polyethylene template, were studied by a combination of electron microscopy, XPS and EPR techniques. The electronic structure and local environment of point defects in the TiO2 mesocrystals were deduced from experimental and simulated EPR data. The Ti3+/F centers and oxygen defects were shown to be the most photosensitive. The presence of carbon radicals was also demonstrated. Since the point defects govern TiO2 photosensitivity and photocatalytic activity in the visible spectral range, the data obtained provide new insights into photocatalytic reactions engineering using titania mesocrystal

New insights into polymer mediated formation of anatase mesocrystals

The reaction between (NH4)2TiF6 and H3BO3 in the presence of varying quantities of PEG-6000 was used to form NH4TiOF3 mesocrystals (MCs). The amount of PEG-6000, employed as a template, is crucial to the formation of defect free, non-agglomerated NH4TiOF3 MCs; high concentrations lead to MC agglomeration, lower ones result in centralized defects. This polymer-mediated formation process may be understood using an analogy with known polymerization reactions. The oxofluorotitanate MCs readily undergo a thermal topotactic transformation to give anatase MCs with photocatalytic activity. The TiO2 MCs are porous, with highly orientated lamellar crystallites that form part of the larger mesocrystal structure

Health Expenditure Trends in East Asian and Pacific Countries, 1995-2010

Class of 2014 AbstractSpecific Aims: To classify East Asian and Pacific countries into homogenous groups based on potential determinants of their healthcare expenditures and public health care. Methods: We used data from the 1995 to 2010 World Health Organization (WHO) database. Cluster analysis techniques were applied to identify clusters of East Asian and Pacific countries using variables identified as potential determinants of healthcare expenditures and public health care. Differences between clusters of countries were validated using Analysis of Variance (ANOVA). Average annual growth rate (AAGR) was calculated to study the change in trends across countries over time. Main Results: Nineteen countries with complete data were included. Of those, we identified four distinct clusters. Cluster 1 consisted of Cambodia, Laos, Mongolia, Solomon Islands, Timor-Leste and Vanuatu. Cluster 2 represented China, Myanmar, and Vietnam. Cluster 3 consisted of Fiji, Indonesia, South Korea, Malaysia and Thailand. Cluster 4 represented Micronesia, Papua New Guinea, Philippines, Samoa and Tonga. Health Expenditure per capita AAGR (P=0.002), infant mortality rate AAGR (P=0.018), life expectancy at birth AAGR (p=0.003), population ages 65 and above AAGR (P=0.004) and death rate (P<0.001) were found to be significantly different among the clusters. Clusters were similar based on birth rate (P=0.425) and public health expenditure (P=0.231), though there were trends of differences. Conclusion: East Asian and Pacific countries were similar based on birth rate and public health expenditure, but were different based on health expenditure per capita, infant mortality rate, life expectancy at birth, population ages 65 and above and death rate. Exploration of clusters among countries may increase the chances of success for health policies and innovations at lower costs of targeted implementation at a global level.This item is part of the Pharmacy Student Research Projects collection, made available by the College of Pharmacy and the University Libraries at the University of Arizona.

Obtaining organic dairy products using common thyme as antibiotic replacing therapy of endometritis in cows

According to the Federal Law of August 3, 2018 No. 280-FZ organic agriculture is referred to as total economic activity that enables the development of ways, methods and technologies that promote favorable state of the environment and improve human health. The need for this law is dictated by the data of the Research Institute of Nutrition of the Russian Academy of Sciences, which claim that 30-50% of all diseases of Russians arise from the consumption of poor-quality food. 30% of the pollution of the world ecosystem refer to an agricultural sector, which is an obvious need for the greening of agriculture and the production of organic products. Organic products mean environmentally friendly agricultural products, raw materials and food in the production of which the following requirements are met: the use of agrochemicals is prohibited, pesticides and antibiotics, growth stimulants are absent, and hormones are not used in animal fattening. Taking into account Russian legislation, the products of dairy cattle breeding should not indicate the presence of oxytetrocycline, levomycetine, streptomycin, tetracycline, ampicillin, penicillin, grisin, bacitrocin. Natural resistance in cows is reduced as a result of negative factors (stress factors) characterizing the industrial technology for the production of livestock products itself, and negative environmental factors. Currently, the development of dairy cattle breeding and the increase in animal productivity are restrained by the high incidence of diseases of the reproductive organs, among which a significant part are inflammatory diseases of the genitals, in particular endometritis (up to 90% of the total number of calving cows). The use of herbal preparations in folk and traditional veterinary science and medicine makes it relevant to search for new plants for obtaining medicinal raw materials in the treatment and prevention of endometritis. Common thyme is proposed as such. The article shows the results of using common thyme for cows with endometritis as antibiotic replacement therapy, which confirmed by an increase in a number of biochemical blood indicators and the overall health of animals

Infrared and Terahertz Spectra of Sn-Doped Vanadium Dioxide Films

This work reports the effect of tin (Sn) doping on the infrared (IR) and terahertz (THz) properties of vanadium dioxide (VO2) films. The films were grown by hydrothermal synthesis with a post-annealing process and then fully characterized by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), and temperature-controlled electrical resistivity as well as IR and THz spectroscopy techniques. Utilizing (NH4)2SnF6 as a Sn precursor allows the preparation of homogeneous Sn-doped VO2 films. Doping of VO2 films with Sn led to an increase in the thermal hysteresis width while conserving the high modulation depth in the mid-IR regime, which would be beneficial for the applications of VO2 films in IR memory devices. A further analysis shows that Sn doping of VO2 films significantly affects the temperature-dependent THz optical properties, in particular leading to the suppression of the temperature-driven THz transmission modulation. These results indicate Sn-doped VO2 films as a promising material for the development of switchable IR/THz dichroic components

Enhanced gas separation factors of microporous polymer constrained in the channels of anodic alumina membranes

New composite membranes based on porous anodic alumina films and polymer of intrinsic microporosity (PIM-1) have been prepared using a spin-coating technique. According to scanning electron microscopy, partial penetration of polymer into the pores of alumina supports takes place giving rise to selective polymeric layers with fiber-like microstructure. Geometric confinement of rigid PIM-1 in the channels of anodic alumina causes reduction of small-scale mobility in polymeric chains. As a result, transport of permanent gases, such as CH(4), becomes significantly hindered across composite membranes. Contrary, the transport of condensable gases (CO(2), С(4)H(10)), did not significantly suffer from the confinement due to high solubility in the polymer matrix. This strategy enables enhancement of selectivity towards CO(2) and C(4)H(10) without significant loss of the membrane performance and seems to be prospective for drain and sweetening of natural gas

Ceramics Based on Sodium Rhenanite CaNaPO₄, Obtained via Firing of Composite Cement-Salt Stone

Ceramics based on rhenanite CaNaPO4 with density of 0.94 g/cm3 and compressive strength of 10.3 MPa was obtained via firing at 900 °C of composite cement-salt stone prepared from a hardening powder mixture of calcium citrate tetrahydrate Ca3(C6H5O7)2∙4H2O and sodium dihydrogen phosphate NaH2PO4. The phase composition of the obtained samples of cement–salt stone was represented by monetite CaHPO4, unreacted sodium dihydrogen phosphate and calcium citrate tetrahydrate. According to the XRD data, the phase composition of the ceramic samples after annealing in the temperature range of 500–700 °C was mainly represented by the β-CaNaPO4 phase. It was found that after an annealing at temperature of 900 °C, the phase composition of ceramics was presented with the only phase of β-CaNaPO4. It was demonstrated that an increase in the annealing temperature led to an increase in the grain size from 1 μm after annealing at 500 °C to 5 μm after annealing at 900 °C. Obtained ceramic material based on CaNaPO4 could be important for regenerative treatments of bone tissue defects
