In the late 1990s on the market of high-quality real estate in Russia became popular a luxury apartment building called "club house". However, frequently the proposed design solutions do not meet the requirements for the architectural organization of this class dwelling. The aim of the research is to determine the optimal architectural and planning parameters of "club houses", identified on the basis of the analysis of the project implementations experience.The prerequisite for the appearance of such objects was the decision of the Moscow government to ban the construction of multi-storey houses in the historic center of the capital. To build in the center the usual multi-storey houses for the mass consumer was not correct. The solution of this problem was proposed by developers – an elite low-apartment house, built or renovated on an exclusive project in a prestigious landscaped area for a narrow circle of residents belonging to the same social class and having a high material and property level. The new type of housing immediately interested wealthy citizens.

Advice Quality

Background Seeking health information on the internet is very popular despite the debatable ability of lay users to evaluate the quality of health information and uneven quality of information available on the Web. Consulting the internet for health information is pervasive, particularly when other sources are inaccessible because of time, distance, and money constraints or when sensitive or embarrassing questions are to be explored. Question and answer (Q&A) platforms are Web-based services that provide personalized health advice upon the information seekers’ request. However, it is not clear how the quality of health advices is ensured on these platforms. Objective The objective of this study was to identify how platform design impacts the quality of Web-based health advices and equal access to health information on the internet. Methods A total of 900 Q&As were collected from 9 Q&A platforms with different design features. Data on the design features for each platform were generated. Paid physicians evaluated the data to quantify the quality of health advices. Guided by the literature, the design features that affected information quality were identified and recorded for each Q&A platform. The least absolute shrinkage and selection operator and unbiased regression tree methods were used for the analysis. Results Q&A platform design and health advice quality were related. Expertise of information providers (beta=.48; P=.001), financial incentive (beta=.4; P=.001), external reputation (beta=.28; P=.002), and question quality (beta=.12; P=.001) best predicted health advice quality. Virtual incentive, Web 2.0 mechanisms, and reputation systems were not associated with health advice quality. Conclusions Access to high-quality health advices on the internet is unequal and skewed toward high-income and high-literacy groups. However, there are possibilities to generate high-quality health advices for free.

Abstract Narrative open-ended questions are suitable for gathering detailed information without limiting respondents to a predefined set of response categories. However, despite efforts to improve the quality of open-ended responses using different verbal and visual design features, respondents are often unwilling to expend effort on substantive and comprehensive responses. Based on a Web survey experiment conducted with opt-in panelists in Germany, we test whether placeholder text (i.e., lorem ipsum) in the answer box of a narrative open-ended question can be used as a visual stimulus to promote high-quality responses without discouraging respondents from answering the question. We find that, although placeholder texts that suggest long and extensive responses elicit more extensive responses, they also result in longer response times and less substantive responses. As the disadvantages of such lengthy placeholder texts thus appear to outweigh their advantages, we advise against using them. We further find that shorter placeholder texts do not provide any additional benefits. These findings also suggest that any kind of visual design feature should always be tested thoroughly before use.

High-rise characteristics of skyscrapers in different countries, including Russia, are given. There are promising projects of constructing new skyscrapers. These high-rise structures have their own design features, they are objects of a high responsibility level, and require arranging reliable geodetic support to be constructed and operated. The specifi cs of high-rise construction geodetic support are noted. The role of high-quality support increases with the amount of fl oors. The errors of the formwork removal to the installation horizons are considered. The accuracy requirements for geodetic operations and precision of creating a planned reference network are formed. The methods of transmitting plane coordinates to high horizons and the disadvantages of the currently used technologies are shown. Recommendations for the use of new geodetic technologies in high-rise construction are formulated. The ways of high-rise structure fl uctuations geodetic monitoring based on using video displacement sensors, GPS receiver, video hydrostatic sensors and inclinometers are presented. Measurements are performed with special computer programs. The proposed geodetic technology has been tested in Russia in a number of construction sites. Recommendations on the use of modern geodetic technologies in high-rise construction, depending on the height, are presented.

The unique 70-cm meniscus-type telescope of the Abastumani Astrophysical Observatory supplied with two objective prisms and the seeing conditions characteristic at Mount Kanobili (Abastumani) permit us to obtain stellar spectra of a high quality. No additional design to improve the “climate” immediately around the telescope itself is being applied. The dispersions and photographic magnitude limits are 160 and 660Å/mm, and 12–13, respectively. The short-wave end of spectra reaches 3500–3400Å.

Standard Techniques

Standard techniques of electropolishing silver and silver alloys for electron microscopy in most instances have relied on various CN recipes. These methods have been characteristically unsatisfactory due to difficulties in obtaining large electron transparent areas, reproducible results, adequate solution lifetimes, and contamination free sample surfaces. In addition, there are the inherent health hazards associated with the use of CN solutions. Various attempts to develop noncyanic methods of electropolishing specimens for electron microscopy have not been successful in that the specimen quality problems encountered with the CN solutions have also existed in the previously proposed non-cyanic methods.The technique we describe allows us to jet polish high quality silver and silver alloy microscope specimens with consistant reproducibility and without the use of CN salts.The solution is similar to that suggested by Myschoyaev et al. It consists, in order of mixing, 115ml glacial actic acid (CH3CO2H, specific wt 1.04 g/ml), 43ml sulphuric acid (H2SO4, specific wt. g/ml), 350 ml anhydrous methyl alcohol, and 77 g thiourea (NH2CSNH2).

High Quality

A scanning microscope using a field emission source has been described elsewhere. This microscope has now been improved by replacing the single magnetic lens with a high quality lens of the type described by Ruska. This lens has a focal length of 1 mm and a spherical aberration coefficient of 0.5 mm. The final spot size, and therefore the microscope resolution, is limited by the aberration of this lens to about 6 Å.The lens has been constructed very carefully, maintaining a tolerance of + 1 μ on all critical surfaces. The gun is prealigned on the lens to form a compact unit. The only mechanical adjustments are those which control the specimen and the tip positions. The microscope can be used in two modes. With the lens off and the gun focused on the specimen, the resolution is 250 Å over an undistorted field of view of 2 mm. With the lens on,the resolution is 20 Å or better over a field of view of 40 microns. The magnification can be accurately varied by attenuating the raster current.

Induced Defects

Due to the wealth of information, both analytical and structural that can be obtained from it TEM always has been a favorite tool for the analysis of process-induced defects in semiconductor wafers. The only major disadvantage has always been, that the volume under study in the TEM is relatively small, making it difficult to locate low density defects, and sample preparation is a somewhat lengthy procedure. This problem has been somewhat alleviated by the availability of efficient low angle milling.Using a PIPS® variable angle ion -mill, manufactured by Gatan, we have been consistently obtaining planar specimens with a high quality thin area in excess of 5 × 104 μm2 in about half an hour (milling time), which has made it possible to locate defects at lower densities, or, for defects of relatively high density, obtain information which is statistically more significant (table 1).
