The paper briefly describes the methods for testing soils by triaxial compression. Among the many mechanical characteristics of the soil, deformation and strength properties remain as the main and widely used ones, the determination of which is an important experimental task. In recent years, new test schemes, more advanced designs of instruments and equipment for the study of various soils have been proposed. Like any material, the soil has limited strength, and under certain external influences the soil massifs collapse, as a result of which their individual parts get unlimitedly large displacements. Triaxial soil compression is becoming more widespread in the production of engineering and geological studies to justify the construction projects of various engineering structures. Based on the results of this work, recommendations for the practical application of the obtained soil characteristics for the geotechnical geoinformational database of the city of Nur-Sultan are made.

The article outlines issues which arise when conducting research on wheelchair (reconstructed) ramps of existing buildings, technical re-equipment of building porches and buildings or their construction projects for compliance with building standards and regulations. As a method of research we have chosen visual inspection of construction and planning solutions, namely measuring of geometric parameters of over 30 ramps in different districts in the city of Kharkiv has been conducted. Requirements of current building regulations are analyzed, their applicability to public and residential buildings for access by persons with reduced mobility is established. Main types of violations of building standards and regulations while construction of ramps, which create significant obstacles for people with limited mobility to access residential and public buildings, have been identified and systematized. Recommendations are provided regarding the possibility of making necessary changes in the design of ramps and adapted porches of residential and public buildings in order to prevent injury to persons with reduced mobility.

A cocaína é uma das drogas mais consumidas no mundo, sendo o Brasil uma importante rota do tráfico internacional de droga e também um grande mercado consumidor. As várias formas de apresentação da cocaína são feitas a partir da pasta base, a qual também pode ser consumida como droga de abuso. Por passar por diversos atravessadores a pasta base pode sofrer diversas adulterações até chegar ao seu destino final. O objetivo deste trabalho foi avaliar o perfil das apreensões de pasta base na cidade de Recife – PE no período de 2001 a 2015, tendo como base os dados do Instituto de Criminalística Prof. Armando Samico (ICPAS) e também determinar a composição química da droga. Os primeiros casos de apreensão de pasta base ocorreram no ano de 2006 e o ano de 2010 foi o ano que apresentou o maior número de casos de apreensão da droga. A composição química revelou que a pasta base possui em média 51% de cocaína na sua composição e a fenacetina foi o adulterante mais encontrado presente em 31% dos casos. As políticas públicas impactam diretamente nos resultados das apreensões de drogas, sobretudo de pasta base. Mudanças nas políticas de redução da demanda de drogas ao longo dos anos em Pernambuco ocasionou mudança nos perfis das apreensões. A determinação da composição química pode auxiliar tanto no combate ao tráfico como também no tratamento dos usuários de drogas.AbstractCocaine is one of the most consumed drugs in the world, being Brazil an important route of international drug trafficking and also a large consumer market. The many forms of cocaine presentation are made from cocaine base, which can also be consumed as an abuse drug. By passing through several crossings the cocaine base can undergo several adulterations until reaching its final destination. The objective of this work was to evaluate the profile of cocaine base seizures in the city of Recife – PE in the period from 2001 to 2015, based on data of the Institute of Criminalistics Prof. Armando Samico (ICPAS) and also determine the drug chemical composition. The first cases cocaine base seizures occurred in the year of 2006 and the year 2010 presented the largest number of drug seizure cases. Chemical composition revealed that cocaine base has on average 51% cocaine in its composition and phenacetin was the most commonly found adulterant present in 31% of the cases. Public policies have a direct impact on the results of drug seizures, especially of cocaine base. Changes in drug demand reduction policies over the years in Pernambuco have caused changes in seizure patterns. Determination of chemical composition can help both in combating drug trafficking and in drug users treatment.

Serial Mode

Determination of the microstructure and microchemistry of small features often provides the insight needed for the understanding of processes in real materials. In many cases, it is not adequate to use microscopy alone. Microdiffraction and microspectroscopic information such as EELS, X-ray microprobe analysis and Auger spectroscopy can all contribute vital parts of the picture. For a number of reasons, dedicated STEM offers considerable promise as a quantitative instrument. In this paper, we review progress towards effective quantitative use of STEM with illustrations drawn from studies of high Tc superconductors, compound semiconductors and metallization of H-terminated silicon.Intrinsically, STEM is a quantitative instrument. Images are acquired directly by detectors in serial mode which is particularly convenient for digital image acquisition, control and display. The VG HB501A at Cornell has been installed in a particularly stable electromagnetic, vibration and acoustic environment. Care has been paid to achieving UHV conditions (i.e., 10-10 Torr). Finally, it has been interfaced with a VAX 3200 work station by Kirkland. This permits, for example, the acquisition of bright field (or energy loss) images and dark field images simultaneously as quantitative arrays in perfect registration.

Beam Damage

Biological materials damage rapidly in the electron beam, limiting the amount of information that can be obtained in the transmission electron microscope. The discovery that observation at cryo temperatures strongly reduces beam damage (in addition to making it unnecessaiy to use chemical fixatives, dehydration agents and stains, which introduce artefacts) has given an important step forward to preserving the ‘live’ situation and makes it possible to study the relation between function, chemical composition and morphology.Among the many cryo-applications, the most challenging is perhaps the determination of the atomic structure. Henderson and co-workers were able to determine the structure of the purple membrane by electron crystallography, providing an understanding of the membrane's working as a proton pump. As far as understood at present, the main stumbling block in achieving high resolution appears to be a random movement of atoms or molecules in the specimen within a fraction of a second after exposure to the electron beam, which destroys the highest-resolution detail sought.

Abstract Chronic cough is the most frequent reason cited by patients for seeking medical care in an ambulatory setting and may account for 10% to 38% of a pulmonologist's practice. Because chronic cough can be caused by or correlated with a wide array of disorders and behaviors, the diagnosis of etiologic factors and determination of appropriate therapeutic management in these cases can prove to be daunting for the physician and speech-language pathologist alike. This article will describe the phenomenon of chronic cough, discuss the many etiologic factors to consider, and review some of the more common ways in which speech-language pathologists and physicians collaborate to treat this challenging condition.

Trade is a form of business that is run by many people around the world, ranging from trading various kinds of daily necessities or primary needs, to selling the need for luxury goods for human satisfaction. For that, to overcome the many needs of life, they try to outsmart them buy products that are useful, economical and efficient. One of the markets they aim at is the second-hand market or the so-called trashy market. As for a trader at a trashy market, they aim to sell in the used goods market with a variety of reasons. These reasons include; first, because it is indeed to fulfill their needs. Second, the capital needed to trade at trashy markets is much smaller than opening a business where the products come from new goods. Third, used goods are easily available and easily sold to buyer. Here the researcher will discuss the behavior of Muslim traders in a review of Islamic business ethics (the case in the Jagalan Kediri Trashy Market). Kediri Jagalan Trashy Market is central to the sale of used goods in the city of Kediri. Where every day there are more than 300 used merchants who trade in the market. The focus of this research is how the behavior of Muslim traders in the Jagalan Kediri Trashy Market in general. Then, from the large number of traders, of course not all traders have behavior in accordance with Islamic business ethics, as well as traders who are in accordance with the rules of Islamic business ethics. This study aims to determine how the behavior of Muslim traders in the Jagalan Kediri Trashy Market in buying and selling transactions and to find out how the behavior of Muslim traders in the Jagalan Kediri Trashy Market in reviewing Islamic business ethics. Key Words: Trade, loak market, Islamic business
