Published: September 2017

Abstract
Rapid urbanization affecting demand patterns, coupled with potential water shortages due to supply side impacts of climatic changes, has led to the emergence of new technologies for water and wastewater reuse. Sewer mining (SM) is a novel decentralized option that could potentially provide non-potable water for urban uses, including for example the irrigation of urban green spaces, providing a mid-scale solution to effective wastewater reuse. SM is based on extracting wastewater from local sewers and treatment at the point of demand and entails in some cases the return of treatment residuals back to the sewer system. Several challenges are currently in the way of such applications in Europe, including public perception, inadequate regulatory frameworks and engineering issues. In this paper we consider some of these engineering challenges, looking at the sewer network as a system where multiple physical, biological and chemical processes take place. We argue that prior to implementing SM, the dynamics of the sewer system should be investigated in order to identify optimum ways of deploying SM without endangering the reliability of the system. Specifically, both wastewater extraction and sludge return could result in altering the biochemical process of the network, thus unintentionally leading to degradation of the sewer infrastructure. We propose a novel Monte-Carlo based method that takes into account both spatial properties and water demand characteristics of a given area of SM deployment while simultaneously accounting for the variability of sewer network dynamics in order to identify potential locations for SM implementation. The outcomes of this study suggest that the method can provide rational results and useful guidelines for upscale SM technologies at a city level.

Вертикальный транспорт исследован в гетеропереходах II типа с двухбарьерной квантовой ямой AlSb/InAs/GaSb/AlSb, выращенной методом МОГФЭ (MOVPE) на подложке n-InAs(100), в квантующих магнитных полях до B=14 Тл при низких температурах, T=1.5 и 4.2 K. Ширина квантовых ям выбиралась из условия получения инвертированной зонной структуры. Измерения осцилляций Шубникова-де-Гааза проводились при двух ориентациях магнитного поля (перпендикулярной и параллельной) относительно плоскости структуры. Установлено, что проводимость в исследуемой структуре осуществлялась как трехмерными (3D) электронами подложки, так и двумерными (2D) электронами квантовой ямы InAs в условиях квантового предела для объемных электронов (B&gt;5 Tл). Определены концентрации электронов в подложке и в квантовой яме InAs, а также g-фактор для трехмерных носителей из спинового расщепления нулевого уровня Ландау. Показано, что максимумы кондактанса в магнитном поле, перпендикулярном плоскости структуры и параллельном току через структуру, в полях B&gt;9 Тл соответствуют резонансному туннелированию 3D электронов из подложки-эмиттера в квантовую яму InAs через 2D электронные состояния уровней Ландау.

Published: September 2017

OBJECTIVE
Severe hypoglycemia is a rare but important complication of type 2 diabetes. Few studies have examined the epidemiology of hypoglycemia in a community-based population.

RESEARCH DESIGN AND METHODS
We included 1,206 Atherosclerosis Risk in Communities (ARIC) Study participants with diagnosed diabetes (baseline: 1996–1998). Severe hypoglycemic events were identified through 2013 by ICD-9 codes from claims for hospitalizations, emergency department visits, and ambulance use. We used Cox regression to evaluate risk factors for severe hypoglycemia.

RESULTS
The mean age of participants was 64 years, 32% were black, and 54% were female. During a median follow-up period of 15.2 years, there were 185 severe hypoglycemic events. Important risk factors after multivariable adjustment were as follows: age (per 5 years: hazard ratio [HR] 1.24; 95% CI 1.07–1.43), black race (HR 1.39; 95% CI 1.02–1.88), diabetes medications (any insulin use vs. no medications: HR 3.00; 95% CI 1.71–5.28; oral medications only vs. no medications: HR 2.20; 95% CI 1.28–3.76), glycemic control (moderate vs. good: HR 1.78; 95% CI 1.11–2.83; poor vs. good: HR 2.62; 95% CI 1.67–4.10), macroalbuminuria (HR 1.95; 95% CI 1.23–3.07), and poor cognitive function (Digit Symbol Substitution Test z score: HR 1.57; 95% CI 1.33–1.84). In an analysis of nontraditional risk factors, low 1,5-anhydroglucitol, difficulty with activities of daily living, Medicaid insurance, and antidepressant use were positively associated with severe hypoglycemia after multivariate adjustment.

CONCLUSIONS
Poor glycemic control, glycemic variability as captured by 1,5-anhydroglucitol, kidney damage, and measures of cognitive and functional impairments were strongly associated with increased risk of severe hypoglycemia. These factors should be considered in hypoglycemia risk assessments when individualizing diabetes care for older adults.

THE AFFECTING FACTORS ADDRESSED IN EFL ESSAY CLASS OF UM METRO LAMPUNG IN RESPECT TO THE STUDENTS’ PERCEPTION AND THE LECTURER’S REFLECTION
Authors: - Dedi Turmudi 
Published: September 2017

This research paper discusses a number of key points addressed in teaching essay writing course of EFL class in Indonesia. The lecturer applied some various techniques in teaching, including a new proposed technique called FBFRP technique (Turmudi 2013) which basically leads to assist learners in self regulatory process in writing composition ( Magno, 2009). Research goals were to disclose some critical points and to what extents of each point was qualified compared among the addressed issues. This research was a descriptive reflective expose-facto and the primary data was taken with instruments: tests, reflection, and questionnaires resulting a descriptive qualitative with quantitative data output. The subjects or participants were 100 undergraduate students of English Department enrolled at essay writing class and the objects were the students’ responses on the addressed points formatted in a rating scale questionnaire (Sugiono, 2009).The data analysis was first hand data as exposed-facto data which was processed through a set of procedures. No statistical inferences were reported but descriptive statistics and logical inferences. The result turned out that none of all components were dominants; but a certain technique as medium to assist the students’ ability to write computer-based-essay test was needed to develop. Thus, this research has the same red thread with that of Magno (2009) hypothesizing that learners of EFL tend to use specific approach to learning and eventually undergo self regulatory process.

Authors: - Merry Rullyanti 
Published: September 2017

Swearwords are natural part of our language. They are used as the most healing way to throw away some extra frustration or anger in a difficult situation. Anderson lists three different motives for swearing: psychological motives, social motives and linguistic motives. The primary aim in this research is to find out swearwords that are commonly used by Bengkulunese people and the most frequent motives behind them. There are 20 Bengkulunese people as the participants of this research who filled in questionnaire. The questionnaire contained a table which consisted of two columns. The first is the swearwords column and the second one is the circumstances of the occurred swearwords which must be filled in by the participants completely. Based on the swearwords gained from the participants, there are 43 swearwords that are generally used by them in their daily speaking activity. Some of them are still in Indonesian language version and some other swearwords are from Bengkulunese language version. For example the word “sialan” and “kurang ajar” are Indonesian languages that are still understood by those who are not Bengkulunese, while the word “sea’”, “bigal”, or “cuk mak” are based from Bengkulunese language.
A CRITICAL THOUGHT OF INSTRUCTIONAL STRATEGY: DEVELOPING ANALYTICAL CAPABILITY OF AUTOMOTIVE STUDENTS BY MANAGING MORE APPLICABLE MOVIE FRAGMENTS, POWER POINT, AND INTERACTIVE TEST
Authors: - Agus Riyanto 
Published: September 2017

What most sensed about Technical High School (known as SMK) students is their lack of analytical capability. As their nature of academic orientation is aimed at job fullfillment, the students are enhanced to follow Standard Operational Procedure (SOP) without questioning why such SOP should be followed. As for automotive students, they simply following the steps of doing things related to any activities of repairing car and other mechanical work required just because the job will be done well when the procedure completed. This kind of mentality “following order or SOP” fits to those who only want to be workers not the men who take higher responsibilities. The progress of automotive technology demand on understanding the concept of how some system used in a car. Failure to comprehend to concept will jeopardize the performance of a car. At the same time, the progress of automotive technology is also propelled by the progress of information technology which provides more open resources that can be used to promote the quality of instuctional process. Realizing that having analysis compentence is terribly important to run higher responsibilites and continuing education to a university, automotive students need to learn how to analyze. To promote this, teacher can use some automotive movies or animations and then chop them into many fragments related to instructional objectives. The way how the teachers arrange and present the fragments can be combined into power point and ended up with an interactive test with different model of methods, strategies, or techniques. Movies, movie cutter application, interactive test Creator , paint into fragments can be obtained freely from the internet.The using of movie fragments integrated into power point, arrange the fragment into various strategies, ended up with interactive test will likely focus the students into more realistic understanding toward the concept taught in the classroom. In return the students will be accustomed to analyze each fragment to building comprehension of concept underlying the skill required in automotive work.

Abstarct --------------------------------------------------------------------------------------------------------------------Vocabulary is one aspects in reading comprehension. By having a lot vocabulary, the students understand in reading comprehension. The interest in English also gives effect of students mastery in English. Before the students start to read they are must be interested in English first. Reading is one of skills in English that very essential for the students, because by reading the students can get information from the text. In this research the researcher focoses on reading comprehension in descriptive text. The problems formulation in this research are; (1) How far is the students score of ability in vocabulary mastery toward reading comprehension in descriptive text? (2) How far is the students score of ability in students interest in English toward reading comprehension in descriptive text? (3) How far is the correlation between students’ score of vocabulary mastery and students interest in English toward reading comprehension in descriptive text?. The objective of the research are; (1) To identify the students’ score in vocabulary mastery toward reading comprehension in descriptive text. (2) To identify the students’ score in students interest in English toward reading comprehension in descriptive text. (3) To find out how far the correlation between students’ score of vocabulary mastery and students interest in English toward reading compregension in descritive text.The research was conducted at the second semester of Muhammadiyah University Students in Academic Year 2014/2015. The population of this research was 127 students. The researcher used cluster ramdom sampling in taking sample. In collecting the data the researcher used test and questionnarie, namely vocabulary mastery and reading comprehension in descriptive text.
