Physical Availability

Consumption of non-beverage alcohol is an important aspect of hazardous drinking, impacting mortality from various causes of death. Since 2005, non-beverage alcohols in Russia have been the subject of active regulation to control their consumption for drinking. This study was purported to determine whether non-beverage alcohols were available in Russia in 2015–2020 to assess the effectiveness of implemented control policies. During the first wave of the survey between 2015 and 2017, 50 Russian cities of various sizes, types, and locations were surveyed. The second wave was conducted between 2018 and 2020 in 5 cities, which were surveyed during the first wave. Fieldworkers visited various retail outlets and purchased samples of non-beverage alcohols: spirituous liquids with an ethanol content of at least 60% by volume sold at a price of less than 45 roubles per bottle ($0.57, €0.49, £0.44). Up until 2016 various types of non-beverage alcohols known as consumed for drinking were available in retail. The availability of these alcohols differed between cities depending on the level of local enforcement of control regulations. The regulations enacted in response to the 2016 Irkutsk outbreak of mass alcohol poisonings, caused by the consumption of methanol containing fake bath additive “Hawthorn”, removed from the market several types of non-beverage alcohols, significantly reducing their availability since 2017. However, low-cost ethanol sources, such as medicinal tinctures, antiseptics, not denatured eau-de-colognes, remained available in 2017-2020, while new sorts of cheap non-beverage alcohols suitable for drinking were introduced to the market (antiseptics for veterinary use, anti-SARS-CoV-2 hand sanitizers). Illegal alcoholic beverages commonly produced from diverted pharmaceutical/medicinal ethanol were also available in retail networks selling non-beverage alcohols. Since 2005, policies implemented and especially those reinforced and newly enacted in 2017 and later in response to the 2016 Irkutsk outbreak, may have indeed reduced the physical availability of non-beverage alcohols. However, more decisive action is still required to prevent consumption of newly appearing and existing specific sorts of non-beverage alcohols and illegal alcoholic beverages, which are commonly produced from the licit or diverted from the legal market unrecorded illicit pharmaceutical/medicinal ethanol.

Second Wave

This essay takes its cue from second-wave ecocriticism and from recent scholarly interest in the “appropriate technology” movement that evolved during the 1960s and 1970s in California and elsewhere. “Appropriate technology” (or AT) refers to a loosely-knit group of writers, engineers and designers active in the years around 1970, and more generally to the counterculture’s promotion, development and application of technologies that were small-scale, low-cost, user-friendly, human-empowering and environmentally sound. Focusing on two roughly contemporary but now largely forgotten American texts Sidney Goldfarb’s lyric poem “Solar-Heated-Rhombic-Dodecahedron” (1969) and Gurney Norman’s novel Divine Right’s Trip (1971)—I consider how “hip” literary writers contributed to eco-technological discourse and argue for the 1960s counterculture’s relevance to present-day ecological concerns. Goldfarb’s and Norman’s texts interest me because they conceptualize iconic 1960s technologies—especially the Buckminster Fuller-inspired geodesic dome and the Volkswagen van—not as inherently alienating machines but as tools of profound individual, social and environmental transformation. Synthesizing antimodernist back-to-nature desires with modernist enthusiasm for (certain kinds of) machinery, these texts adumbrate a humanity- and modernity-centered post-wilderness model of environmentalism that resonates with the dilemmas that we face in our increasingly resource-impoverished, rapidly warming and densely populated world.

This chapter examines the socio-economic motivations behind the shaping of retail landscapes in Roman cities. It is about who opened retail outlets, as well as why and where. After critiquing some of the normal methods for illustrating the locations of shops and bars, including the conventional distribution plan itself, as well as questioning the economic rationality of operating tabernae, this chapter argues for the value in complicating our otherwise basic understanding of why urban investments were made in the places we find them. Rather than accepting profit as the single motivation to urban investment, a range of social, economic, and political motivations are considered as an explanation for the ultimate shape of Roman retail landscapes. Thus beyond discussions of space and urban topography, the subject of this chapter is investment.

Due to the vast distances across the country as well as between urban centres, Australia is heavily reliant upon its air transport industry. Following deregulation of Australia's domestic air travel market on the 30th October, 1990, low cost carriers have entered the market. Australia's LCC market has had three discrete phases. The first wave occurred between 1990 and 1993 and was subsequently followed by a duopoly period in 1994–1999. The second wave occurred between 2000 and 2006 and the final wave has been in the post-2006 period. This paper examines the evolution of Australia's domestic low cost carrier airline market and finds that by 2010, low cost carriers had captured around 64 per cent of the market. Following the evolution of the “Virgin Australia” business model from a low cost carrier to a full service network carrier, commencing in 2011, the low cost carrier's market share has declined significantly and is now around 31 per cent. “Jetstar” and “Tiger Airways” are the two major carriers presently operating in this market segment.

Вхождение Российской Федерации в Евразийский экономический союз обусловило ужесточение требований, предъявляемых к показателям безопасности алкогольной продукции, в том числе к упаковочным средствам. Алкогольные напитки хранятся и даже выдерживаются в упаковке, поэтому укупорочный материал – корковая пробка может существенно влиять на качество напитка. В связи с этим к корковым пробкам предъявляются требования безопасности в форме контроля содержания формальдегида. Существующие способы его идентификации достаточно трудоемки и весьма затратны, а также предусматривают использование дорогостоящего оборудования. Предлагаемый метод определения содержания формальдегида, выделяющегося из корковых пробок в модельные среды, разработан на основе мицеллярной электрокинетической капиллярной хроматографии с использованием процесса дериватизации контролируемого соединения раствором 2,4-динитрофенилгидразин (2,4-ДНФГ) в ацетонитриле, содержащем 5% уксусной кислоты. Для исследования использовали систему Капель 105, снабженную УФ-детектором с переменной длиной волны, кварцевые капилляры диаметром 75 мкм и общей длиной 60 см (50,5 см до детектора). Рабочие растворы формальдегида готовили ежедневно путем соответствующего разбавления образцов исходного раствора водой. Калибровочные графики были рассчитаны для шести концентраций – 2, 5, 10, 20, 40 и 100 мг/л стандартов в двух повторностях. В образцы – модельные среды, полученные при исследовании образцов корковых пробок, добавляли определенное количество стандартного раствора формальдегида и проводили процедуру дериватизации. УФ-детектирование производных 2,4-ДНФГ проводили при длине волны 360 нм. Результаты апробации метода представлены на электрофореграммах. Получена линейная зависимость между площадью пика и концентрацией формальдегида (R2 = 0,99). Разработанный метод определения содержания формальдегида малозатратен, отличается простой и высокой точностью и может быть рекомендован в качестве инструмента контроля безопасности корковых пробок в соответствии со стандартами Евразийского экономического союза. The entry of the Russian Federation into the Eurasian economic Union has led to stricter requirements for the safety indicators of alcoholic beverages, including packaging products. Alcoholic beverages are stored and even aged in the packaging, so the corking material – cork plugs can significantly affect the quality of the drink. In this regard, cork plugs are subject to safety requirements in the form of formaldehyde control. Existing methods for identifying it are quite time-consuming and very expensive, and also involve the use of expensive equipment. The proposed method for determining the content of formaldehyde released from cortical plugs into model media was developed on the basis of micellar electrokinetic capillary chromatography using the process of derivatization of a controlled compound with a solution of 2,4-dinitrophenylhydrazine (2,4-DNPH) in acetonitrile containing 5% acetic acid. System Kapel 105 equipped with a UV-detector with a variable wavelength, quartz capillaries with a diameter of 75 microns and a total length of 60 cm (50,5 cm to the detector) were used for the study. Working solutions of formaldehyde were prepared daily by appropriately diluting the samples of the initial solution with water. Calibration graphs were calculated for six concentrations – 2, 5, 10, 20, 40 and 100 mg/l standards in two repetitions. A certain amount of standard formaldehyde solution was added to the sample – model media obtained during the study of cork plugs samples and a derivatization procedure was performed. UV detection of 2,4-DNPH derivatives was performed at a wavelength of 360 nm. The results of testing the method are presented on electrophoregrams. A linear relationship was obtained between the peak area and the formaldehyde concentration (R2 = 0,99). The developed method for determining the formaldehyde content is low-cost, simple and highly accurate, and can be recommended as a tool for monitoring the safety of cork plugs in accordance with the standards of the Eurasian economic Union.

Teaching wireless networking fundamentals is often difficult because many students appear to find the subject technical, and dry when presented in traditional lecture format. To overcome this problem, we provide an opportunity for experiential learning where students can learn wireless networking fundamentals by hands-on practical activities using low-cost Wi-Fi (wireless fidelity) devices such as wireless cards and access points. Students can easily set up and configure networks using wireless cards and access points more effectively. By measuring network performance such as throughput and end-to-end delays, students are able to gain a deeper understanding of wireless networking. The effectiveness of Wi-Fi-based practical activities has been evaluated by students and the teaching team. This chapter reports on the overall effectiveness of teaching and learning of wireless network using radially available low-cost Wi-Fi cards and access points.

<p class="0abstract"><span lang="EN-US">One of the drawbacks of using 3D printers in educational environments is that the creation time of each piece is high and therefore it is difficult to manufacture at least one piece for each student. This aspect is important so that each student can feel part of the manufacturing process. To achieve this, 3D printers can be used, not to make pieces, but to make the molds that students use to create replicas. On the other hand, for a mold to be used to make several pieces, it is convenient to make it with flexible material. However, most used material for 3D printers (PLA) is very rigid. To solve this problem, this article designs a methodology that allows the use of low-cost 3D printers (most common in school environments) with flexible material so that each mold can be used to manufacture parts for several students. To print flexible material with low-cost printers, it is necessary to adapt the machine and the print parameters to work properly. This article analyzes the changes to be made with a low cost 3D printer and validates the use of molds in school environments. A pilot test has been carried out with 8 students of the subject of Typography, in the School of Art and Superior of Design of Tenerife. During the activity, the students carried out the process of designing a typography and creating digital molds for 3D printing with flexible material. The designs were made using free 3D modeling programs and low-cost technologies.</span></p>

This paper provides a review of advances in conjugated polymer lasers. High photoluminescence efficiencies and large stimulated emission cross-sections coupled with wavelength tunability and low-cost manufacturing processes make conjugated polymers ideal laser gain materials. In recent years, conjugated polymer lasers have become an attractive research direction in the field of organic lasers and numerous breakthroughs based on conjugated polymer lasers have been made in the last decade. This paper summarizes the recent progress of the subject of laser processes employing conjugated polymers, with a focus on the photoluminescence principle and excitation radiation mechanism of conjugated polymers. Furthermore, the effect of conjugated polymer structures on the laser threshold is discussed. The most common polymer laser materials are also introduced in detail. Apart from photo-pumped conjugated polymer lasers, a direction for the future development of electro-pumped conjugated polymer lasers is proposed.

This paper discusses a low cost head-supported eye tracker. To measure the coordinates associated with a subjects gaze point fallen on a monitor, the subject places his head on a head support and keeps his head fixed. Meanwhile, a camera is used to capture images of the subjects left or right eye. The subjects gaze point fallen on a monitor can be determined according to the relative position of the pupil and glint in an eye image. This paper presents not only the principle of this eye tracker, but also the methods used to detect the pupil and glint in an eye image. At last, this paper presents some experimental results, and the experimental results show that the maximal average error of the experimental apparatus is 15 pixels or 0.4 in degrees.

AbstractThe aim of the project is the development of an aid for blind or visually impaired people, considering economic aspects as well as easy adaptability to various daily situations. Distance sensors were attached to a walking frame (rollator) to detect the distance to obstacles. The information from the sensors is transmitted to the user via tactile feedback. This is realized with a number of vibration motors which were located at the upper belly area of the subject. To test the functionality of the aid to the blind, a testing track with obstacles has been passed through by a number of volunteers. While passing the track five times the needed time to pass through, as well as the number of collisions, were noticed. The results showed a decline in the average time needed to pass though the testing track. This indicates a learning process of the operator to interpret the signals given by the tactile feedback.
