Biopunk Dystopias Genetic Engineering, Society and Science Fiction
Authors: Schmeink Lars
Published: December 2021

'Biopunk Dystopias' contends that we find ourselves at a historical nexus, defined by the rise of biology as the driving force of scientific progress, a strongly grown mainstream attention given to genetic engineering in the wake of the Human Genome Project (1990-2003), the changing sociological view of a liquid modern society, and shifting discourses on the posthuman, including a critical posthumanism that decenters the privileged subject of humanism. The book argues that this historical nexus produces a specific cultural formation in the form of "biopunk", a subgenre evolved from the cyberpunk of the 1980s. The analysis deals with dystopian science fiction artifacts of different media from the year 2000 onwards that project a posthuman intervention into contemporary socio-political discourse based in liquid modernity in the cultural formation of biopunk. Biopunk makes use of current posthumanist conceptions in order to criticize contemporary reality as already dystopian, warning that a future will only get worse, and that society needs to reverse its path, or else destroy all life on this planet. As Rosi Braidotti argues, "there is a posthuman agreement that contemporary science and biotechnologies affect the very fibre and structure of the living and have altered dramatically our understanding of what counts as the basic frame of reference for the human today" (40). The proposed book analyzes this alteration as directors, creators, authors, and artists from the field of science fiction extrapolate it from current trends.
Design and Testing of a Hybrid Shaft-Pod Propulsor for a High Speed Sealift Ship
Authors: Black Scott D. , Cusan Dominic S.
Published: December 2021

The hybrid shaft-pod contra-rotating propulsor configuration has been demonstrated to offer increased efficiency and maneuvering performance over conventional propulsor configurations. The design and testing of this propulsor concept for a large 39 knot high speed sealift application is described here and compared with the performance of a baseline shaft and strut mounted propulsor. This hybrid contra-rotating configuration uses twin tractor propulsion pods to power the aft propellers of the contra-rotating set, where the forward propellers are powered by conventional shaft lines. The design process used a number of design and analysis tools to develop a propulsor intended to operate at 39 knots while avoiding thrust breakdown. The propulsor geometry was manufactured and tested in open water at two different scales and used in powering and cavitation tests. Software predictions against the open water data demonstrated that performance predictions can accurately be made for this type of propulsor. The absence of thrust breakdown at speeds above the 39 knot design speed was demonstrated. The powering performance of the hybrid pod configuration will be discussed relative to experimental data obtained for a conventional shaft and strut design for the same hull form.
The Effect of Cupping on Four-Quadrant Propeller Performance
Authors: Dowsett Jonathan H. , Duerr Phillip S. , Hadler Jacques B. , Rose Robin S.
Published: December 2021

The Webb Hydroflite Propeller Series (WHPS) consists of four matching pairs of three-bladed ten-inch-diameter pleasure craft propellers with P/D ratios varying from 0.6 to 1.2. Recently, one propeller from each matching pair was modified with a uniform trailing edge cup. Cupping is a widely employed and inexpensive aftermarket alternative to repitching a propeller that is not performing in a given application. The hydrodynamic performance characteristics of each modified propeller were determined by open-water and four-quadrant model tests prior to and after cupping. Performance comparisons were made for each pair of propellers tested to determine the level of manufacturing consistency as well as the effects of cupping. Test data for peak open-water efficiency and four-quadrant performance were compared to B-Series propeller data to determine whether the B-Series can be used confidently for performance predictions. It was found that the addition of the cup could be modeled as an increase in effective pitch. For a given KT/J2 operating curve, the cupped propeller operates at a higher advance coefficient than the original propeller when running ahead. The increase in advance coefficient leads to lower shaft speed at a given thrust. When running astern, there is little change in the KT curve for the cupped propeller and therefore negligible change in advance coefficient but there is a large increase in the required torque at a given shaft speed.
Multi-Jackbolt Tensioner Type Expansion Bolts for Marine Applications
Authors: Busalacchi Stephen J.
Published: December 2021

This paper introduces and discusses the multi-jackbolt tensioner (MJT) type expansion bolt with split expanding sleeve as a replacement to standard fitted or interference fit bolts that are widely used within industry, including navy and marine environments. For marine uses, applications include shaft and propulsion coupling bolting as well as on anchoring and positioning bolting often required for most line shaft bearings, thrust bearings, and steering gears. Both a Finite Element Method (FEM) study and a shear test were recently performed to confirm superior load carrying ability as compared to standard fitted bolts. Further, results of these tests, installation / removal time comparisons, and calculated costs savings are presented here for consideration.
An Environmentally Preferable Lubricant for Tunnel and Azimuth Thrusters
Authors: Sada Hiroyuki , Yamajo Seiji , Hawkins David W.
Published: December 2021

Ocean-going vessels use oil lubrication in the tunnel thrusters. Offshore vessels also use oil lubrication in the azimuth thrusters. Oil leakage from the thrusters is a serious environmental issue in these vessels. In this paper, a water-soluble, environmentally preferable lubricant newly developed for such thrusters is outlined. Properties required for a thruster lubricant and a suitable base fluid are discussed. Environmental compatibility (biodegradability, low toxicity and no sheen or sludge formation), viscosity, lubricity, oxidation stability, rust prevention and seal compatibility of the new lubricant are described. These properties show that for tunnel and azimuth thrusters the new lubricant can improve not only their environmental compatibility but also their seawater tolerance. Field experience of the thruster lubricant is also presented.
A Hybrid Viscous/Potential Flow Method for the Prediction of the Wetted and Cavitating Performance of Ducted Propellers
Authors: Kinnas Spyros A. , Jeon Chan-Hoo , Tian Ye
Published: December 2021

This paper presents the analysis of the performance for various ducted propellers using a hybrid numerical method, which couples a vortex lattice method (VLM) for the analysis of propellers and a Reynolds-Averaged Navier-Stokes solver for the prediction of the viscous fluid flow around the duct. The effects of viscosity on the effective wake and on the performance of the propeller blade, as well as on the predicted duct forces, are assessed. The prediction of the performance for those ducted propellers from the present method is validated against existing experimental data.
Propeller hydrodynamic loads in relation to propulsion shaft alignment and vibration calculations
Authors: Batrak Yuriy A. , Shestopal Valentyn P. , Batrak Roman Y.
Published: December 2021

In spite of recent CFD progress, simple methods for the estimation of the propeller hydrodynamic loads through stationary non-uniform wake in relation to cargo ship shafting alignment and vibration calculations are still demanded. The paper concerns with the propeller load calculation results obtained on the base of widely used approaches implemented by the authors in propulsion shaft calculation software. Practical recommendations for setting of propeller hydrodynamic loads in the case of lack of data for full calculation are proposed. The procedure for the propeller load validation in relation to the shaft alignment criteria is discussed.
Las viajeras francesas en Rusia (1766-1870). Percepciones y miradas sobre el país de los zares
Authors: Gijón Jimenez Verónica
Published: December 2021

Con la llegada del siglo XVIII, Francia y Rusia estrecharon sus lazos, las ideas de la Ilustración calaron profundamente entre la aristocracia rusa y aumentó significativamente el número de ciudadanos franceses que viajaban a Rusia. En el siglo XVIII, las mujeres comenzaron a luchar por sus derechos, y durante la centuria siguiente fueron conquistando espacios que habían sido tradicionalmente masculinos. El viaje fue uno de los ámbitos donde aumentó la presencia de las mujeres. Las viajeras francesas también visitaron el país de los zares, y muchas de ellas dejaron testimonios valiosos para conocer el pasado de esta nación. El objetivo de este artículo es analizar las percepciones que tuvieron las viajeras del arte y la cultura rusa. También tendremos presente el papel que jugaron estas mujeres en Rusia que, en muchos casos estuvo estrechamente ligado con los cambios políticos, sociales y culturales que estaban teniendo lugar en la época.
¡No son las criaturas, es la Academia! Brechas salariales de género y carrera investigadora en la Universidad
Authors: Samper-Gras Teresa , Jabbaz Marcela , Tomás Sergio , Ferrer Andrea
Published: December 2021

El objetivo del presente texto es presentar a la maternidad como argumento que naturaliza las dificultades de las mujeres en sus carreras académicas y que desplaza a los actuales criterios de evaluación científica. A partir de un estudio sobre la brecha salarial en la Universitat de València se identifican y se confrontan situaciones salariales como la penalización por maternidad y el plus salarial por paternidad para tratar de reconocer cómo opera una institución meritocrática. Se analiza el complemento salarial por sexenios que reconoce salarialmente la productividad de hombres y mujeres que ocupan posiciones estables en launiversidad y sus repercusiones en las distintas áreas de conocimiento según su estilo competitivo. Las consecuencias que ha generado la pandemia de la COVID-19 para las mujeres académicas pueden agravarse si solo observamos como problema la falta de conciliación sin propuestas para el cambio de evaluación que rige la I+D+i.
Analysis of the Performance of Cellular Mobile Networks for the Remote-Control Systems of Unmanned Aerial Vehicles. Summary of the Doctoral Thesis
Authors: Brodņevs Deniss
Published: December 2021

The Thesis is concerned with assessing the suitability of LTE (4G) cellular networks for the remote control of low-flying UAVs. To solve this problem, an approach to the analysis of the delay values in cellular networks has been developed, which makes it possible to estimate the delays of individual cells and overall cellular network. Requirements for delays in the UAV control channel were developed, conclusions were drawn about the suitability of the LTE network as a communication solution for the UAV remote control. A method for calculating the effect of parallel redundancy is proposed, and an experimental assessment of the possibility of using two existing solutions for parallel redundancy in LTE networks is carried out. In addition, a compact technical solution for analyzing the level of base station signals was demonstrated.
Awareness and knowledge of cyberethics: A comparative study of preservice teachers in Malta, Norway, and Spain
Authors: Milton Josephine , Giæver Tonje Hilde , Mifsud Louise , Gassó Héctor Hernández
Published: December 2021

This paper explores the knowledge and understanding of cyberethics held by preservice teachers across three European countries. The study was conducted via an online survey and yielded a total of 1,131 responses from preservice teachers in Spain, Norway, and Malta. The facets of cyberethics included in this study were specifically related to behaving responsibly online, safeguarding privacy, respecting copyright, seeking consent of third parties before posting images or videos on social media platforms, and considering their own professional identity as future teachers when posting images or videos online. The findings indicate that preservice teachers reported similar levels of competence in both applying copyright and respecting privacy rules. However, this varied across countries, with preservice teachers in Malta and Norway reporting higher levels of knowledge and awareness than their counterparts in Spain. Malta had the largest number of participants who reported that they ‘always’ considered the potential impact that posting media online may have on their careers, followed by Norway. Spain had the largest number of preservice teachers who stated that they rarely or never thought about this impact on their teaching career. Our findings highlight the need for student teachers’ knowledge of cyberethics to be prioritised during ITE, especially within the framework of developing a professional digital identity. In light of our findings, we recommend that all ITE programmes include digital competence and cyberethics components in their curricula. This would enable preservice teachers to develop an emerging professional and digital identity to face the challenges of becoming teachers in the 21st century.

Authors: Hong Mihwa , Han Sujeong
Published: December 2021

Purpose: This study was done to identify the mediating effect of compassion competence on the relationship between communication competence and caring behavior in clinical nurses.Methods: A structured self-report questionnaire was used to measure caring behavior, communication competence, and compassion competence. During September 2019, data were collected from 170 nurses working at general hospitals. Data were analyzed using hierarchical multiple linear regression with SPSS for Windows version 23.0 and Hayes's SPSS process macro (version 3.5).Results: Communication skills (β=.52) and compassion ability (β=.77) were identified as important predictors of nurses’ caring behavior. These variables explained approximately 54% of the variance in nurses’ caring behavior. Compassion competence also had a total mediating effect on the relationship between communication competence and caring behavior.Conclusion: In order to enhance the caring behavior of clinical nurses, enhancing compassion competence by strengthening communication development should be considered as a strategy.

Data were analyzed using SPSS version 25 to provide descriptive statistics of the participants’ general characteristics and empathy level and to perform repeated-measures analysis of variance for the sub-constructs empathy.Results: Perspective taking (F=13.08, p<.001) and personal distress (F=5.24, p=.001), but not fantasy or empathic concern, showed significant differences over time.Conclusion: Cognitive empathy (perspective taking) and emotional empathy (personal distress) improved. Intervention programs should be developed to maintain and strengthen changes in empathy in nursing education.
Predictive Value of Neutrophil Lymphocyte Ratio and Platelet Lymphocyte Ratio in Immediate Outcomes of ST-elevation Myocardial Infarction: A Cross-sectional Study
Authors: Sadashiva Sneha Barkur , Chenthil KS
Published: December 2021

Introduction: There have been various inflammatory markers implicated in the pathogenesis of Acute Coronary Syndromes (ACS). However, the role of the Neutrophil Lymphocyte Ratio (NLR) and Platelet Lymphocyte Ratio (PLR) as prognostic markers in ST-elevation Myocardial Infarction (STEMI) remains poorly researched. Aim: To determine the prognostic value of NLR and PLR to predict the immediate outcomes in patients with acute STEMI, and if any association exists between NLR/PLR and Thrombolysis in Myocardial Infarction (TIMI) risk score. Materials and Methods: This was a cross-sectional study conducted at a tertiary care centre, Puducherry, India, where 190 patients who presented to casualty with STEMI were enrolled. The patient co-morbidities, personal and family history were obtained. The routine laboratory parameters including platelets, lymphocytes, neutrophils and their corresponding ratios were calculated. Patients were grouped into low and high NLR/PLR groups and were assessed for occurrence of in-hospital mortality or Major Adverse Cardiovascular Events (MACE). Analysis was made to see if there is an association between NLR/PLR and MACE. Chi-square test and one-way ANOVA test was used for statistical significance. Results: Among 190 subjects, 157 male and 33 female with mean age of 55.72±11.24 years were included. A total of 8.94% patients 8.94% had MACE. NLR was positively associated with MACE (p-value=0.0006), whereas PLR was not associated with MACE. Patients with high NLR had 1.45 times higher odds of having MACE. NLR was significantly associated with TIMI risk score. Both NLR (F ratio=6.341) and PLR (F ratio=4.600) showed significant association with Killip classification, however NLR showed higher association (p-value <0.001). Conclusion: NLR can be used as a powerful prognostic marker for predicting immediate MACE and death in STEMI patients. In addition, NLR showed positive correlation with Killip classification and TIMI risk score.

Authors: Слюняев А.В. , Пелиновский Е. Н.
Published: December 2021

Приведен обзор исследований опасного природного явления — неожиданного возникновения необычайно высоких волн на морской поверхности (так называемых волн-убийц). Объясняется, чем такие волны отличаются от обычных гравитационных волн, возникающих под действием ветра, и какова, согласно базовым теоретическим моделям, вероятность образования высоких волн. В простой форме приводятся основные предположения, которые заложены в существующие модели прогноза ветрового волнения, и показано, в чем их недостаточность для объяснения появления волн-убийц. Обсуждается связь волн-убийц с ключевыми решениями приближенных уравнений гидродинамики (солитонами, солитонами огибающей, бризерами), а также неоднозначный взгляд на роль эффектов нелинейной самомодуляции волн в открытом океане. Приводится общая гипотетическая концепция прогноза ветровых волн в океане и обсуждаются новые подходы для прогноза волн, учитывающие эффект волн-убийц.
По реке Оленёк — 500 километров на веслах, или Один полевой сезон из жизни геологов, "Природа"
Authors: Специус З.В.
Published: December 2021

Статья посвящена полевой экспедиции, организованной с целью переоценки алмазоносности северных полей в Якутской алмазоносной провинции. Задача состояла в поиске кимберлитовых тел на четырех полях, открытых и опробованных шурфами или скважинами в 1970-е годы. Из них нужно было отобрать образцы кимберлита и отмыть тяжелую фракцию индикаторных минералов, чтобы впоследствии по минералогическим критериям оценить перспективы алмазоносности. Данные кимберлитовые поля были расположены в бассейне р.Оленёк; полевые работы были выполнены тремя специалистами с использованием двух резиновых лодок без мотора, что делало сплав менее быстрым, но зато менее затратным. Статья сформирована в виде полевого дневника. В ней изложено передвижение по маршруту с описанием всех перипетий этого нелегкого, но увлекательного путешествия и с характеристикой отдельных видов уникальной природы Якутии.

Рассмотрена история открытия закона теплового действия тока. Дано сравнение вклада двух авторов закона — английского физика Дж.Джоуля и российского физика Э.Х.Ленца. Показано, что установлению закона предшествовал — причем у обоих — период увлечения конструированием электродвигателей. Подчеркнуто, что для Джоуля открытие закона теплового действия тока стало началом экспериментов по определению механического эквивалента теплоты. Большое значение для понимания закона теплового действия тока имели его эксперименты с токами индукционного происхождения. Отмечено активное участие Джоуля в работе научных обществ.
Эволюция Земли: от зарождения до появления ноосферы, "Природа"
Authors: Кузьмин М.И. , Ярмолюк В.В. , Горячев Н.А. , Диденко А.Н.
Published: December 2021

В статье рассмотрена геологическая истории Земли от ее образования до сегодняшних дней. Наша планета зародилась в составе Солнечной системы спустя примерно 9.2 млрд лет после возникновения Вселенной. В хаотичный период (4568–4500 млн лет назад) произошли аккреция Земли, дифференциация ее на ядро и мантию и формирование Луны. В гадейский эон (4.5–4.0 млрд лет назад) началась геологическая история планеты. В течение этого времени ее формирование контролировалось постоянными астероидными бомбардировками. С раннего архея (4.0–3.1 млрд лет назад) космический фактор перестал быть определяющим, ведущую роль стали играть механизмы тектоники покрышки и мантийных переворотов, которые обеспечивали дифференциацию недр Земли в условиях их более высокого разогрева. В этот этап зарождается твердое железное ядро. В переходный период (3.1–2.0 млрд лет назад) значимым тектоническим режимом была тектоника малых литосферных плит, резко возросла скорость корообразования, в строении верхней мантии выделилась астеносфера, а в низах мантии сформировался слой D . Поздний период геологической истории (<2 млрд лет назад) контролировался процессами глобальной тектоники, которая включала тектонику литосферных плит и тектонику мантийных плюмов. Она определяла суперконтинентальную цикличность развития Земли и резкое усиление металлогенического разнообразия в то время. В целом геологическая эволюция Земли отличалась усложнением строения, зарождением и упрочнением различных геосфер, включая биосферу и ноосферу. Главный ее итог — формирование на Земле условий для появления и успешного развития человека и человеческой цивилизации.

Александр Петрович создал школу морской геологии в России. Им разработаны новые научные направления в области морской геологии: учение о роли взвешенного вещества в океанском осадкообразовании и биодифференциации вещества в океане, о геологической истории океанов и палеоокеанологии, о маргинальных фильтрах океана, о зональном характере биогенной, лавинной, ледовой и аридной седиментации.
Редкие виды млекопитающих: проблемы сохранения популяций (Чувашская Республика), "Природа"
Authors: Александрова О.С. , Желтов П.В.
Published: December 2021

Наш век отмечен появлением новых угроз для редких животных. Их среда обитания меняется под влиянием деятельности человека и в результате продолжающегося изменения климата планеты. В таких условиях ведущим инструментом контроля влияния этих процессов на природу вообще и на животный мир нашей страны в частности становится государственный экологический мониторинг и проводящийся в его рамках учет объектов животного мира. Такой учет представляет собой систему регулярных наблюдений за распространением, численностью и физическим состоянием животных, а также за структурой, качеством и площадью среды их обитания. В Чувашской Республике такой мониторинг ведется уже многие годы. Рассмотрим, как организован учет животных, и попробуем проанализировать динамику численности некоторых редких и уязвимых видов млекопитающих, обитающих в заповедниках и заказниках нашего региона за последние 10 лет.

Значение дистанционного зондирования Земли из космоса для изучения природной среды переоценить невозможно: от исследования растительности и водных ресурсов до геологического и геоморфологического картографирования. Количество спутников, ведущих ежедневную съемку земной поверхности из космоса, уже давно перевалило за сотню, а архивы космических данных измеряются петабайтами. При увеличении числа спутниковых систем ДЗЗ значительно улучшается качество и особенно разрешающая способность съемочной аппаратуры, достигшая уже пространственного разрешения 0.3 метра. Сегодня не менее 10 космических платформ ведут съемку в субметровом разрешении. Но при всех современных технологических возможностях космической съемки существуют такие объекты и природные процессы, картографирование и мониторинг которых можно проводить только на основе данных сантиметрового разрешения при комбинации космических, воздушных и наземных методов дистанционного зондирования. Некоторые процессы и явления до сих пор не нанесены даже на крупномасштабные карты, а скорости их протекания известны недостаточно точно или вовсе не определены.

В последние десятилетия наблюдается стремительное развитие спутниковых систем дистанционного зондирования Земли (ДЗЗ). При этом и быстро увеличивается число спутников ДЗЗ, и происходит фактически взрывной рост объемов спутниковых данных. Наиболее значимый прогресс в области развития и применения систем ДЗЗ произошел в XXI веке. Именно в это время не только резко расширились возможности спутниковых наблюдений Земли, но появились и стали наиболее активно использоваться системы нового поколения, которые позволяют получать не только информацию для качественных оценок наблюдаемых явлений и объектов, но и хорошо калиброванные и пространственно-привязанные данные, которые могут быть использованы для количественных оценок и моделирования различных процессов, происходящих на Земле. Фактически, появление таких систем открыло новую эру спутникового дистанционного зондирования и позволило приступить к созданию принципиально новых, высокоавтоматизированных технологий работы с данными ДЗЗ. Эти технологии обеспечивают организацию эффективной работы со сверхбольшими массивами данных, полученными при проведении постоянных спутниковых наблюдений практически в любом регионе нашей планеты.

Authors: Караваева Е.Э.
Published: December 2021

В статье рассматривается прощание с протестантским государем Эдуардом VI в условиях общей политической нестабильности и прихода к власти королевы-католички Марии I. Автор анализирует комплекс вопросов, связанных с подготовкой завещания Эдуарда VI, поминальными церемониями и похоронами монарха. Траур по Эдуарду VI, включавший и протестантские, и католические элементы, оказывается принципиальным свидетельством политического и религиозного кризиса, в котором Англия находилась в середине XVI в. Параллельно публичной протестантской службе в Вестминстерском аббатстве в Тауэре проходит католическая месса, и именно на последней присутствует преемница почившего Эдуарда VI на английском престоле Мария I и послы иностранных государств. Работа основывается как на письменных (в том числе архивных) источниках, так и на изобразительных памятниках.

Рецензируемая монография представляет собой переиздание этой книги, вышедшее в свет на французском языке в 1992 г., дополненное автором с учетом новейших исследований. Она содержит богатый материал по истории латинского языка Поздней Античности и Раннего Средневековья и формирования на его основе западно-романских языков, но не является систематическим изложением фактов, характеризующих этот процесс. Перед нами исследование одного из важнейших его аспектов: соотношения в эту эпоху литературного латинского языка, с одной стороны, и разговорного – с другой. Анализируя самые разные источники (трактаты, проповеди, жития святых, хроники, акты церковных соборов, в меньшей мере документы и надписи), автор приходит к выводу, что до конца VIII в., в Италии – до конца IX в. и даже позднее, сохранялось определенное единство между языком образованной элиты и языком плохо или вовсе не образованного населения, что обеспечивало вертикальную коммуникацию между этими социальными группами. Сохранялась и возможность коммуникации на одном языке во всем ареале романской части Европы. Эти выводы очень важны для осмысления социокультурных процессов данной эпохи и информативности дошедших до нас источников. Критически воспринимая некоторые выводы, содержащиеся в данной книге, авторы рецензии оценивают ее очень высоко.
Quantitative Assessment of Serum Magnesium Levels in Head and Neck Cancer: A Tertiary Hospital Based Case Control Study
Authors: Kumar Surender , Salaria Neha , Verma Deepak , Garg Uma , Verma Monika
Published: December 2021

Background- Head and neck squamous cell carcinomas(HNSCC) are one of the most widespread malignancies worldwide. Trace elements such as magnesium are essential at cellular level, and it has been suggested that magnesium plays a role in carcinogenesis.

Methods- A hospital based case control study was conducted in a tertiary care medical college with an aim to determine the levels of serum magnesium in patients with head and neck cancer and to  compare  the  levels  of  serum  magnesium  of head and neck cancer patients   with healthy matched control  group  and  derive significance if any.

Results- HNSCC was mainly found in males of age group 46 to 55 years. The mean serum Mg value of head and neck cancer patients was 0.71± 0.18 mmol/l while that seen in controls was 0.85± 0.09 mmol/l which was significantly lower(p<0.001). Average serum magnesium levels in stages I, II, III and IV were 0.85, 0.849, 0.682 and 0.554 mmol/l respectively, and a statistically significant association was determined between the two.

Conclusion- As the stage of cancer progressed, average magnesium levels decreased congruently, hence establishing that magnesium levels were undeniably correlated to onset as well as progression of HNC. These evidences could be utilized to identify role of magnesium asa potential prognostic biomarker to assess progression of disease or clinical response to various modes of therapy in head and neck cancer patients.

The aim of this work is to study the acid and enzymatic hydrolysis of water yam peels using HCl, H2S04 acids and cellulase enzyme. The cellulase was secreted from Aspergillus niger (A.niger). The proximate analysis of the substrate showed that water yam peel is a lignocellulosic biomass with a cellulose composition of 48%. The effect of the process parameters (time, temperature, acid concentration and pH) on the yield of glucose in acid and enzymatic hydrolysis of the water yam peel was respectively investigated. Maximum glucose yield of 44.5% was obtained after 3 days of enzymatic hydrolysis at 30°C and pH 5. The HCl acid hydrolysis showed a maximum glucose yield of 27.3% at 70°C, 5% HCl after 180 minutes. The glucose yield in H2S04 hydrolysis was relatively lower than that of the HCl with a maximum yield of 26.5% at 70°C, 5% H2SO4 after 180 minutes. In addition to, the functional groups present in the glucose synthesized from ground water yam peels and the standard glucose were evaluated using Fourier Transformed Infrared (FTIR) Spectroscopy. The FTIR results showed similarities in the functional groups present in both sugars. Yam peel can be used for the production of glucose and further fermentative process to produce ethanol.

Aim: Polymer flooding is used for enhanced oil recovery. Only polymers that can withstand harsh environments work best. HPAM is mostly the polymer used for enhanced oil recovery because it is available and cheap, but it does not withstand high temperatures and high salinity reservoirs. Xanthan Gum withstands high temperatures and high salinity reservoirs, but it is expensive and plugs the reservoir. The aim of this study is to compare the salinity stability of gum Arabic and Terminalia Mantaly, a novel biopolymer, with commercial Xanthan gum.

Study Design: Locally formulated biopolymers from gum Arabic exudates bought from Bauchi State in Nigeria and from Terminalia Mantaly exudates obtained from the University of Port Harcourt. The appropriate rheological tests were carried out at the laboratory.

Place and Duration of Study: The laboratory experiments were carried out at the department of Petroleum Engineering, Covenant University, Ota in Ogun State of Nigeria between 2020 and 2021.

Methodology: The gum Arabic, Terminalia Mantaly and Xanthan Gum powders were dissolved in deionized water to get various concentrations in ppm. The polymers were mixed and kept for 24 hours to achieve a homogenous solution. The Automated OFITE® Viscometer at different revolutions per minute (RPM) of 3 (Gel), 6, 30, 60, 100, 200, 300, and 600 was used to measure the rheological properties of the various concentrations before Sodium Chloride (NaCl) and Calcium Chloride (CaCl2) of various concentrations were added and allowed to hydrate for another 24 hours before measuring their rheological properties again.

Results: The study showed that Xanthan Gum, Gum Arabic, and Terminalia Mantaly biopolymers can be used in high salinity reservoirs. Terminalia Mantaly, a novel biopolymer, is insensitive to salinity in monovalent and divalent ions.

Conclusion: Xanthan gum exhibited high viscosity even at low concentrations. Gum Arabic exhibited good tolerance to salinity at NaCl 3.5%. Terminalia Mantaly was very stable with both monovalent and divalent ions. Divalent ions have more effects on polymers than monovalent ions in reservoirs.

Recommendation: It is recommended that Terminalia Mantaly be investigated more, as it can replace imported biopolymers for Enhanced Oil Recovery (EOR).

Published: December 2021

Background: Loss of teeth affects the masticatory ability and overall health of the patient especially posterior teeth as they contribute more to mastication as compared to anteriors. Loss of teeth can lead to undesirable consequences and early rehabilitation with any type of prosthesis can lead to desirable changes and thus missing teeth should be replaced as soon as possible.

Aims and Objectives: To determine the change in masticatory ability and quality of life (QoL) after replacement of missing posterior teeth by fixed dental prosthesis.

Methodology: Maximum bite force was recorded before and after treatment. Also a self-perceived questionnaire was filled by the patient to assess the change in QoL. Patients with missing posterior teeth were included. Patients with acute infections or systemic diseases were excluded.

Results: Significant change (p=0.0001) in both masticatory ability and QoL of the patient was seen. The co-relation of both was clinically significant while statistically non-significant (p=0.77). Results were significant for both the studied parameters but co-relation between them was no significant. It is because of the patients perceived satisfaction of the overall treatment.

Conclusion: Rehabilitation of posterior teeth improves mastication and also overall oral health related QoL.
