System-issues of development of hotel business

The development of a hotel business development strategy should include the following methodological approaches to the sequence of execution of works: the definition of goals and objectives for gaining strategic positions in the market, achieving the necessary technical level and product quality, increasing the efficiency of service delivery; determining the real possibilities of the hotel company for the implementation of the stated goals and objectives; justification of the development strategy, that is, the development of long-term and current measures of economic and financial development of the hotel company in order to provide the above-mentioned tasks; estimation of probable results; the development and adoption of corrective measures to achieve the planned results activity of hotel enterprise.So in deciding to optimize the development of the hotel business, it is necessary to determine the ways of its implementation, that is, to choose the appropriate strategy of activity

Formation of colloidal alloy semiconductor CdTeSe magic-size clusters at room temperature

Alloy magic-size clusters (MSCs) are difficult to synthesize, in part because so little is known about how they form. Here, the authors produce single-ensemble alloy CdTeSe MSCs at room temperature by mixing prenucleation-stage solutions of CdTe and CdSe, uncovering a formation pathway that may extend to the synthesis of other alloy MSCs

The effect of degree of reduction on the electrical properties of functionalized graphene sheets

We study the effect of carbon to oxygen ratio (C/O) on the electrical resistance of functionalized graphene sheets prepared by thermal exfoliation and reduction of graphite oxide at various temperatures. Using a 2-probe technique in conjunction with Kelvin probe force microscopy, we observe a transition from high-resistance (>400 kX/sq) nonlinear current/voltage characteristics at low C/O to low-resistance (<10 kX/sq) linear behavior at high C/O, indicating a transition from hopping to diffusive electron transport. Simultaneously, the metal-graphene contacts change from high-resistance Schottky-type behavior to nearly non-invasive metal-metal contact characteristics

Characterization of German penicillin non-susceptible serotype 23F pneumococci using multilocus sequence typing.

Three nationwide multicentre studies (n = 5071) showed an increase in antibiotic resistance in pneumococci in Germany. Serotype 23F was the predominant serotype (n = 45, 22.4 %), followed by 6B (n = 30, 14.9 %) and 9V (n = 19, 9.5 %). Multilocus sequence typing was used to characterize 45 serotype 23F strains with reduced penicillin susceptibility. The Spanish(23F)-1 clone [profile 4-4-2-4-4-1-1, sequence type (ST) 81] contributes significantly to the emergence of penicillin resistance in Germany (n = 21, 46.7 % of all penicillin non-susceptible serotype 23F isolates). Isolates of ST 277 (profile 7-13-8-6-6-12-8), which has been found previously in the Netherlands, are also observed, particularly in western Germany (n = 8, 17.8 %). A high proportion of strains (n = 11, 24.4 %) have sequence types that have not been reported to date from other countries (STs 353-362). The major penicillin-resistant clones are present in Germany, a country with relatively low levels of beta-lactam resistance

Digital Doping in Magic-Sized CdSe Clusters

Magic-sized semiconductor clusters represent an exciting class of materials located at the boundary between quantum dots and molecules. It is expected that replacing single atoms of the host crystal with individual dopants in a one-by-one fashion can lead to unique modifications of the material properties. Here, we demonstrate the dependence of the magneto-optical response of (CdSe)13 clusters on the discrete number of Mn2+ ion dopants. Using time-of-flight mass spectrometry, we are able to distinguish undoped, monodoped, and bidoped cluster species, allowing for an extraction of the relative amount of each species for a specific average doping concentration. A giant magneto-optical response is observed up to room temperature with clear evidence that exclusively monodoped clusters are magneto-optically active, whereas the Mn2+ ions in bidoped clusters couple antiferromagnetically and are magneto-optically passive. Mn2+-doped clusters therefore represent a system where magneto-optical functionality is caused by solitary dopants, which might be beneficial for future solotronic applications. © 2016 American Chemical Society116151sciescopu
