Frictional Analysis of a Small Two-Stroke Utility Engine via Tear-Down Testing
Authors: RIPIN Zaidi Mohd. , GITANO-BRIGGS Horizon , ABDULLAH Mohd. Zulkifly
Published: June 2024

Two stroke engines are popular power sources for ambulatory applications because of their superior power to weight ratio. Due to fuel short-circuiting however, they suffer from poor fuel economy and high levels of emissions. Small utility two-stroke engines are typically tuned rich to improve ignition stability and cooling. Additionally the presence of fuel in the crankcase requires high rates of two-stroke oil usage to insure proper lubrication. Given rising petroleum prices and concern for the environment, reducing the fuel consumption and emissions of two-stroke engines is of increasing importance.

With the extreme price sensitivity of small two-stroke engines more sophisticated options such as direct fuel injection, are not possible. Instead, the best starting point for fuel consumption improvement is to insure proper carburetor tuning and lubrication of the engine and optimization of the engine's intake and exhaust tuning.

For this study a typical small utility engine was mounted to a motoring dynamometer. The engine was operated at a standard speed for a given length of time with various oil/fuel ratios. Once the engine ran dry the ignition was switched off and the frictional torque was measured as the engine cooled. Frictional measurements were analyzed as a function of lubricant quantity and engine temperature. Finally friction was measured as the engine was progressively dismantled, removing the exhaust system, carburetor, spark plug, piston and connecting rod. Frictional contributions from each source were then tabulated.

Published: June 2024

For a disaster relief and automatic inspections, an unmanned helicopter is strongly expected. To develop this, a very high power density source is required. A Wankel-type rotary engine can be the best candidate for the power source. In this study, the development of a very small rotary engine with a displacement of 30 cc is targeted. In order to improve the combustion efficiency, gas exchange and stable ignition, a multi dimensional simulation inside the combustion chamber was carried out. At first, the effect of volumetric efficiency on the maximum power is mentioned. Secondly, the effect of scavenging efficiency is discussed. Thirdly, a blow off through a plug hole is described. The position of plug hole was found important to reduce the blow off amount. Finally, the effect of combustion speed on the engine performance is predicted. As a result, the proposed design will be tested using a proto-type engine. Also, future subjects to achieve a high power density with a displacement of 30 cc will be solved by the authors' research in progress.
Vernacularisation of Documentary Legal Texts in Northern Europe
Authors: Havinga Anna D.
Published: June 2024

At the transition from medieval to early modern Europe, vernaculars became more commonly used in writing in various domain, including administration and law. In the late Middle Ages, vernaculars seem to gain status and start to be regarded as suitable languages for recording municipal matters. But how did this vernacularisation progress in such documentary legal texts? When and why was Latin replaced by vernaculars? To answer these questions, this article presents diachronic quantitative analyses of the language choice in individual entries of two documentary legal sources: the first eight volumes of the Aberdeen Council Registers (1398–1511) and one volume of the Lübecker Niederstadtbuch (1430–1451). The comparative approach to these multilingual texts allows us to trace vernacularisation processes across two language contexts, uncovering similarities and differences between them. In the council registers from Aberdeen, Scots replaced Latin slowly and gradually – a process that took over a century and was far from finished by 1511. In the text from Lübeck, on the other hand, the shift from Latin to Low German was largely completed within about 30 years. In both cases, language practices of the scribes rather than top-down language policies seem to have driven this development. The scribes’ language choices will have been influenced by the use of vernaculars in other texts, including those in the domain of law, pragmatic considerations, and more general socioeconomic developments. By investigating vernacularisation processes in two sources, this article offers a first comparative account that allows for generalisations beyond individual language contexts and serves as the basis for further research in this area.
Between the Impressionistic and the Arithmetic
Authors: Poppe Erich
Published: June 2024

Empirical historical stylistics is methodologically a difficult field since it ‘perhaps inevitably combines the impressionistic and the arithmetic’ (Guillory 2017: 63). For lesser researched languages or periods, the problems are aggravated because even impressionistic assessments on which further hypotheses and comparative work could be built, are rare. Early Modern Welsh (c. 1500 – c. 1700) is a period to which this qualification applies. This article will discuss some methodological issues and parameters for a micro-stylistic analysis of Early Modern Welsh prose, i.e., on the level of individual sentences. Its approach is bottom-up, taking as its point of departure the introductory paratext to Morys Clynnog’s catechism Athravaeth Gristnogawl (‘Christian Doctrine’, 1568) by its editor Gruffydd Robert. It argues that in the case of lesser research languages, empirical historical stylistics will need to proceed from the analyses of individual texts or text samples which combine quantitative and ‘impressionistic’ interpretative perspectives in order to identify notable recurrent micro-stylistic traits.
Scribal Networks and the Language of Urban Administration
Authors: Oudesluijs Tino
Published: June 2024

This paper considers Early Modern English urban administration in light of the developing supralocal/standard variety. Previously, research scrutinising the language of administration has focused on Middle English rather than on Early Modern English, where studies have thus far mostly focused on private correspondence and printed texts. To shed more light on the language of this under-investigated text type for this period, in this paper I investigate a collection of indentured texts written in Coventry between 1499 and 1600 and explore its language. More specifically, I analyse the use of periphrastic DO, which I subsequently contextualise both in Coventry’s local civic history – focusing on the people involved in creating the documents, e.g. the town clerk and his team of scribes – as well as in the general development of periphrastic DO with regard to the emerging supralocal/standard variety of English. The analysis reveals that periphrastic DO was used to a different extent compared to other text types from the period, most notably that it did not show a decline in the second half of the sixteenth century after what can be described as a ‘slow start’ in the first half. This change in use can be tentatively attributed to a variety of factors in Coventry’s civic history, particularly in the 1570s, but more data from other urban centres is needed to better contextualise this.

The prevalence of psychoactive substance use is increasing globally, and university students are not left behind. Self-report, using questionnaire has been the common method of assessing substance use amongst the students' population. This is, however, fraught with problems of poor reporting and intentional lie. Urine Drug Test (UDT) is a biochemical method that tests the recent use of substances either as a direct test of the psychoactive substance or its metabolite(s). This cross-sectional study aims to study the concordance between self-report and UDT amongst students' population. Two thousand five hundred and fifty students of the University of Ilorin, Nigeria completed a questionnaire based on the World Health Organization (WHO) guidelines for student substance-use surveys. Substances investigated in the survey were alcohol, cigarettes, cannabis, strong and mild stimulants, hypno-sedatives, cocaine, opiate, organic solvents, and hallucinogens. A subset of the total population, made of three hundred and two of the students were, subsequently, selected to participate in the urine drug test using a commercially available 12-items UDT kit. The reported lifetime and current prevalence of the substances were: tobacco, 11.5% and 3.7%; alcohol, 38.4% and 15.4%; cannabis, 9.0%and 3.8%; stimulants 32.5% and 15.8%; sedatives 11.7%, 4.8%, opioids 25.3% and 7.6%; cocaine was 4.7% and 1.6%; Hallucinogenic substances lifetime prevalence was 6.6% and a current prevalence of 1.4%. The lifetime prevalence for solvent use was 7.4% while current use was 1.6%. There was discordance between the outcome of the self-report and the result of UDT. Many respondents who tested positive for one substance or the other did not self-report ever using the substance. In conclusion, there is discordance between selfreport and results of the UDT. Many students who did not report ever use of psychoactive substances tested positive for substances. This study further emphasized the superiority of UDT over self-report for psychoactive substances among university students. We recommend that whenever suspicion of possible psychoactive substance use is made among university students, UDT should be the method of assessment. UDT is equally encouraged in school clinics and sports centres.

Published: June 2024

Temperature is the most important abiotic factor and has a direct influence on the physiology of the organism, affecting nearly all other parameters of the living environment of organisms. Ectothermic organisms are highly endangered in the current crisis climate, as they are unable to use metabolic heat to maintain body temperature. Reptiles are ectothermic vertebrates that are also susceptible to temperature fluctuations. Metabolism, muscle and nervous system function and reproduction are closely linked to reptile body temperature. To study the effects of temperature on oxidative stress, it is necessary to describe the generation of reactive oxygen species (ROS) and how organisms can prevent oxidative stress. This article describes the oxidation-antioxidation processes and the oxidative stress caused by thermal effects in reptiles. In the metabolic processes of aerobic organisms, ROS are continuously generated as by-products of oxidation-reduction reactions and are not primarily harmful. Furthermore, ROS are essential for many physiological functions, e.g., for energy production and for processes in the immune system. The potential toxicity of reactive oxygen radicals under physiological conditions is prevented by the antioxidant defence system. Oxidativestress occurs when the balance between oxidation and antioxidation systems is disturbed by excessive amounts of ROS or by the depletion of antioxidants. It is known that the metabolic rate of reptiles correlates with environmental temperature, making them physiologically more sensitive to temperature fluctuations compared to mammals. However, it must be considered that ectothermic organisms have evolved many thermal adaptations through physiological and behavioural measures to mitigate the resulting oxidative stress. However, further research in the fields of ecology, biogeography and evolution is needed to determine the exact effects of temperature on oxidative stress and the resulting changes in life characteristics in wild populations.

Authors: Surianto Surianto , Khang Freddy Denis
Published: June 2024

The purpose of this study was to determine the attractiveness of Desta and the ‘Main Hakim Sendiri' program had an effect on viewing interest. This study used quantitative-survey method. Survey research method is a type of method carried out by obtaining factual, actual, and systematic information on certain population facts. The survey also obtained information from some respondents who are representative of a population. The research was carried out in the Jabodetabek area so that the wide reach made it easier for researchers to be able to research people who knew the ‘Main Hakim Sendiri ' program. The population taken in this study is in the form of Indonesian people, both men and women and live in Jakarta, Bogor, Depok, Tangerang, or Bekasi with an infinite number. The results of the T test (partial) show that the variables "host attractiveness" (X1) and "tv program" (X2) significantly positively affect viewing interest (Y), which means that the more attractive Desta is as a host and the better the quality of television programs, the higher the audience's interest in watching. In addition, the results of the F test (simultaneous) also revealed that the two variables simultaneously had a significant positive effect on viewing interest, so the hypothesis that "host attractiveness" and "tv program" had a significant positive effect on viewing interest was accepted, while the opposite hypothesis was rejected.

Published: June 2024

Introdução: A cefaleia pós punção dural (CPPD) é uma complicação da punção lombar, um procedimento que, apesar de bem tolerado, está sujeito a adversidades, ocorrendo devido a um vazamento persistente do líquido cefalorraquidiano (LCR) do local da punção dural. A incidência de CPPD pode estar relacionada às características dos pacientes e dos procedimentos. Notou-se que em mulheres jovens até 30 anos, o risco de CPPD é maior quando comparado aos homens, não apresentando diferença a partir da quinta década de vida.
Objetivo: investigar os diferentes sintomas e efeitos gerados pelos diferentes tipos de agulha, como calibre e modo de inserção, que visem reduzir a CPPD.
Métodos: Trata-se de uma revisão sistemática de literatura realizada no período de 2 de agosto a 20 de novembro de 2023 por meio de pesquisas no PubMed. Foram utilizados os descritores: "Post-Dural Puncture Headache” e suas variações do MeSH, sendo submetidos aos critérios de inclusão: estudos em humanos, nos últimos 10 anos, ensaios clínicos e ensaios clínicos controlados e randomizados. Para garantir a qualidade da revisão sistemática foi aplicada a lista de verificação PRISMA de 2020. Resultados: Após investigação estatística, observou-se que as agulhas 25W e 25S demandaram maior tempo médio para a coleta de LCR (15 e 7 min, respectivamente). Ao se comparar 25W com 20Q (3 min), 22S (5 min) e 25S quanto à esta variável, observou-se diferença significativa em todas as comparações.
Conclusão: As agulhas do tipo atraumática foram associadas com redução do risco de desenvolvimento de CPPD quando comparadas às convencionais. Foi constatado que, dentre as agulhas convencionais, a traumática de 25G é melhor para a prevenção de CPPD que a de 22G.

Published: June 2024

Solar powered grain drying machines (PGTM) have advantages over fossil energy, namely they are cheap and simple. However, the main obstacle is the dependence on time and weather. To overcome these weaknesses, it is necessary to create a combined system, namely, a solar and PGTL electric drying system. This machine works during the day and continues at night using electric power. This will speed up the grain drying process without having to wait for the sun to rise. The method of supplying electrical power in the drying room is carried out directly with incandescent lamps installed on the drying racks. The amount of electrical power provided to the lamp is equivalent to the average solar energy during the day that enters the drying room, which is 400 Watts. The drying room used for research has an area of 0.9 x 1 meter and a height of 1.7 meters and is equipped with 5 shelves for placing the grain. The hot air flow in the drying room is used by a blower at 2 speeds, namely 4, 7 and 10 m/sec. The walls of the drying room are covered with aluminum foil to increase the efficiency of lamp heat absorption that can be received by the grain. The performance of an electric grain dryer (PGTL) is expressed in terms of drying efficiency or reduction in water content in the grain (Mw) and machine efficiency,ηpgel. The test was carried out at night for 5 hours with a total amount of grain of 8 kg divided into 4 shelves of 2 kg each. From the test results of the PGTL machine, it was found that the reduction in water content in grain (Mw) at air speeds of 4 m/s, 7 m/s and 10 m/s, respectively, was 7.45%, 7.9%, 9.45%, and machine efficiency respectively 20.1, 21.1% and 25.45%.

Teachers' job gratification is vital as it significantly affects their dedication, enthusiasm, and efficiency in the classroom. This study sought to ascertain the extent of teachers’ job gratification concerning job security, work environment, job responsibilities, and community linkages/attachments, the level of teachers’ service performance, and the significant relationship between the teachers’ job gratification and their service performance at work. The study was carried out in five (5) schools of Jasaan North District, Schools Division of Misamis Oriental. It employed a descriptive-correlational design along with documentary analysis. This study utilized an adapted and modified questionnaire given to the selected teachers (n=143) using the purposive sampling technique. The gathered data were analyzed and interpreted using various descriptive and inferential statistical methods, including frequency and percentage, mean and standard deviation, and the Pearson Product-Moment Correlation Coefficient. Results revealed that respondents have a very high level of job gratification, with Job Security having the highest mean and Community Linkage/Attachments got the lowest mean. Teachers demonstrated a very satisfactory level of service performance. A significant relationship was found between teachers' job gratification and their service performance. Thus, the higher job satisfaction among teachers the better their performance. Schools may continue to foster a supportive and collaborative work environment that boosts teachers' job satisfaction and enhances their performance, ultimately benefiting students and the broader school community.

PERSONAGE AND THE CITY IN THE PLAYS OF THE THAW PERIOD
Authors: Semenova Natalia V.
Published: June 2024

The article analyzes the impact of the urban environment on the interpersonal relationships of the characters in the plays of the late Thaw, examines the process of formation of subjectivity. The material represents two crucial texts of the mid-1960s – “A Warsaw Melody” by Leonid Zorin and “104 pages about love” by Edward Radzinsky. These plays have a lot common features, especially its entourage: the plot displays several meetings of a couple of lovers in various public spaces of a contemporary city. However, the relationship of the characters with the urban environment differs in the melodramas. Gelya and Victor from “A Warsaw Melody” create a polylocal urban text: they appropriate Moscow, turning it into their home, which they then lose. At the same time, the characters are opposed to each other in terms of the way they perceive space (Victor is a “flaneur”, a man of the crowd, Helene is cosmopolitan and feels unbound to any particular site), which ultimately anticipates their separation. In the play “104 pages about love”, the public and the private spheres collide each other, there is an erosion of personal space: Natasha and Electron Evdokimov are always in the focus of collective’s attention. The sounds and noises of the city reproduce the everyday life of the 1960s and become the flagship of Soviet modernity. Although the personages embodying the new Thaw generation do not look like elegant models in the capital’s environment. They are haunted by worries and regrets, and are constantly in search of authenticity and purity. The solution of the contradiction between public and private spheres is the frankest dialogue between Natasha and Electron, which turns out to be possible only after the death of the heroine inside Evdokimov’s mind and outside the bustle of a big city.
EMBEDDED NARATIVES IN MARTIN MCDONAGH’S DRAMA «THE PILLOWMAN»
Authors: Kirman Kira S.
Published: June 2024

When receiving the plays of the British-Irish playwright Martin McDonagh, the reader and viewer pays attention to the presence of episodes that go beyond the objective artistic reality of the characters. Thus, in the play “The Pillowman”, published in 2003, two spaces are clearly distinguished: the world in which the main events unfold (the writer ends up in a police station and is accused of a series of murders) and the fictional space of the writer’s seven stories, or embedded narratives. It is important to note that the boundaries between the two worlds are moving, since the characters actively move between them, resulting in the formation of additional space, which fragmentarily appears before the reader or viewer of the play. Despite the attention of domestic and foreign scientists to the work of Martin McDonagh, many aspects of his dramaturgy remain poorly studied, including the poetics of embedded narratives in the play “The Pillowman,” the understanding of which is the purpose of this article. Embedded narratives, being in synthesis with the main outline of the narrative, play an important role in shaping the plot and the reception of the work by the reader. The author of the article discovers two narrative levels, one of which includes the main storyline, and the other – embedded narratives, stories of the writer Katurian. In the course of analyzing the embedded narratives in the play “The Pillowman,” the author comes to the conclusion that, in the terminology of J. Genette, they are hetero and homodiegetic, and their main function is to amplify the plot, as well as to loosen the boundaries between real and fictional spaces in drama.

Relationship between Access to Clean Water and Child Growth and Development in Kenya
Authors: Onditi Liam
Published: June 2024

Purpose: The aim of the study was to analyze the relationship between access to clean water and child growth and development in Kenya.
Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries.
Findings: Access to clean water significantly impacts child growth and development in Kenya by reducing waterborne diseases like diarrhea, improving hygiene practices, and ensuring adequate hydration. Children with reliable access to clean water experience better nutritional outcomes and enhanced immune function, crucial for their physical growth and cognitive development.
Unique Contribution to Theory, Practice and Policy: Ecological systems theory (Bronfenbrenner), health belief model (Rosenstock) & social determinants of health (SDH) theory may be used to anchor future studies on relationship between access to clean water and child growth and development in Kenya. Expand the implementation of effective water purification technologies and community water supply projects in resource-constrained environments. Advocate for integrated policies that prioritize water security alongside nutrition-sensitive interventions. Policies should support multi-sectoral collaboration between health, water, and sanitation sectors to address the complex interplay between water access and child nutrition.

Penggunaan antibiotik sebagai tambahan pakan akan meninggalkan residu pada tubuh ternak. Hal ini apabila dikonsumsi akan mengakibatkan resistensi antimikroba. Hal ini, akan mengurangi kemampuan antibodi dalam melawan serangan mikroba patogen yang masuk ke dalam tubuh. Oleh karenanya dibutuhkan alternatif alami sebagai pengganti antibiotik dalam upaya peningkatan produktivitas unggas terkhususnya broiler. Whey merupakan hasil samping dari olahan susu yang masih mengandung 50% nutrisi alami dari susu. Oleh karena itu, whey dapat dimanfaatkan sebagai feed additive pada broiler. Tujuan penelitian untuk mengetahui efektivitas whey sebagai feed additive pada broiler. Tujuan penulisan ini adalah mereview artikel penggunaan whey sebagai probiotik dalam pakan broiler. Pemanfaatan whey sebagai substitusi antibiotik dapat meningkatkan performa produksi broiler karena secara nyata mampu meningkatkan penyerapan nutrisi pakan, pertambahan bobot badan, kualitas protein daging tanpa residu, dan menurunkan konversi pakan. Whey menghasilkan asam organik berupa asam laktat yang merupakan hasil metabolisme Bakteri Asam Laktat (BAL). BAL yang terdapat dalam whey dapat berasal dari Lactobacillus sp., Lactococcus lactis sp., Streptococcus thermophilus dan lain lain. Mekanisme kerja whey sebagai feed additive layaknya probiotik dengan cara menekan pertumbuhan mikroba patogen dalam usus dan bukan membunuh mikroba seperti antibiotik. BAL dalam whey menghasilkan enzim-enzim pencernaan seperti lipase, amilase dan protease sehingga proses metabolisme lebih optimal. Hal ini akan mengoptimalkan kekebalan unggas sehingga performa produksi menjadi meningkat.
