Cellulose nanocrystals: source, production and application as a coagulant for water purification
Authors: Ivbanikaro Anna E. , Adeniyi Amos 
Published: April 2023

Abstract

The coagulation/flocculation technique is an old proven method that utilizes chemical coagulants for water purification but there are health and environmental challenges associated with the long-term application of such coagulants. Cellulose fibre is a renewable, eco-friendly polymer found in many materials. It has been widely researched due to its unique properties, especially when processed in the ‘nano’ form as cellulose nanocrystals (CNCs) but nanocelluloses require surface functionalization in order to improve their suitability for various applications. The aim of this review is to provide an in-depth discussion of the current progress in the synthesis of CNCs with recourse to their source, surface chemistry and extraction procedures. Various techniques used for the conversion of CNCs into coagulants were extensively reviewed while the current development on the potential application of CNCs as a coagulant for water remediation was presented. The results obtained from the potential application of modified CNC-based coagulants demonstrate their remarkable coagulation efficiency for the purification of contaminated water. Therefore, global research into the development of CNC-based coagulants at all levels is crucial in order to generate interest in natural coagulants as a potential replacement for chemical coagulants. Furthermore, potential areas for more research were proposed in this review.

Objective During the COVID-19 pandemic, the adopted containment measures
have affected other respiratory virus epidemiology. Consequently, we
aimed to describe the characteristics of respiratory virus infection in
hospitalized pediatric acute respiratory infections (ARIs) patients
prior to and throughout COVID-19 in East China. Methods Nasopharyngeal
secretions were collected from 9782 pediatric ARIs patients hospitalized
in Shaoxing Maternal and Child Health Hospital from January 2018 to
December 2022. Changes in positivity viral detection rates and
epidemiological as well as clinical characteristics were analyzed and
compared. Results 1633 strains of 7 common respiratory viruses were
detected, with a total positive rate of 16.37% (821/5021) in 2018-2019
and 17.06% (812/4761) in 2020-2022. Compared with 2018-2019, RSV
positive rate increased significantly in 2020-2022, while ADV, PIV-2,
PIV-3, and flu-B detection rates were significantly reduced (P
< 0.05). The RSV-positive rate in winter increased
significantly more than in other seasons (P < 0.05), while
PIV-3 was mainly prevalent in spring and summer. Conclusion During the
COVID-19 pandemic, there were significant age distribution and seasonal
differences in respiratory virus infection among hospitalized children
with ARIs in East China.

Toxic metal ions present in environmental water samples and other samples need to be detected for their removal. The detection of trace metal ions using an ion selective electrode (ISE) holds great significance in analytical chemistry. A 4-vinyl pyridine-ethyl acrylate copolymer-polyvinyl chloride (VE-PVC) based polymeric matrix (electrode) has been fabricated by free radical bulk polymerization method which is an example of a green and sustainable method capable of detecting Ni2+ ions even in trace amounts. To fabricate the polymeric matrix (electrode) (PME), VE has been used as an ionophore. Further, the effectiveness of Ni2+ ion ISE has also been investigated in the presence of surfactants and detergents. Its performance has also been analyzed in the presence of plasticizers. The electrode is found to be very useful for the estimation of Ni2+ ions using ethylenediaminetetraacetic acid by potentiometric titration and also in the estimation of presence of Ni2+ ions in water. Compared to other metal ions, the fabricated membrane electrode developed in this work has been found to show efficient and better selectivity towards Ni2+ ions.

Published: April 2023

Abstract
Providing an appropriate length of highway entrance ramps is an important feature that should be considered in freeway design. The recommended minimum acceleration lane length in the Green Book of the American Association of State Highway and Transportation Officials (AASHTO) is currently used for designing entrance ramp terminals. However, in some cases, traffic congestion and crashes are observed when heavy trucks enter freeways, which indicates they could not accelerate enough and did not reach the merge speed at the end of the acceleration lane. Therefore, several scenarios were simulated using a dynamic simulation model (TruckSim) for heavy vehicles with weight to power ratios of 61, 67, 86, and 108 (kg/kW) and grades of zero, ±3, and ±5%. Subsequently, a linear regression model was presented to calculate acceleration lane lengths. The results showed that the acceleration rate of heavy vehicles is not adequate, especially in upgrades. For example, at +5% upgrades, heavy trucks cannot accelerate to the merge speed mentioned in the AASHTO. Conversely, the acceleration rate of heavy vehicles increased in downgrades; therefore, some heavy vehicles were able to achieve merge speed along the proposed length of AASHTO.

Perdebatan tentang perbedaan agama seolah telah menjadi permasalahan yang mengakar, akarnya telah jauh masuk ke dalam tanah sehingga sangat sulit untuk dicabut. Perdebatan keagamaan seolah tidak menemukan titik temu dan justru semakin memanas akibat kemunculan penghakiman terhadap keyakinan atau agama yang berbeda, kondisi ini seolah memposisikan keyakinan satu adalah yang benar sedangkan keyakinan lain adalah sesuatu yang salah. Dengan kondisi ini diperlukan kesadaran beragam dengan sikap moderat sesuai dengan wacana yang cukup sering disampaikan belakangan ini. Sebagai bagian dari keyakinan yang diakui di Indonesia, Hindu sesungguhnya telah memiliki berbagai konsep dalam upaya hidup harmonis di tengah perbedaan yang ada. Berbagai konsep yang dimiliki Hindu tidak hanya sebuah wacana untuk hidup moderat, damai dan harmonis, namun konsep ini mengajarkan umat Hindu untuk dapat menumbuhkan puncak kesadaran berketuhanan dengan menyadari bahwa semua makhluk yang ada adalah manifestasi dari Tuhan. Sehingga tidak ada satu alasanpun bagi umat Hindu untuk menghamiki orang lain apalagi merasa benar dan selalu menyalahkan agama orang lain
Kata Kunci: Hindu, Moderasi, Kesadaran Berketuhanan

Published: April 2023

The design of high-lift devices for commercial aircraft is a multidisciplinary problem. One of the difficulties is that the mechanism is difficult to accurately guide the flap to the aerodynamic design position. Therefore, the traditional high-lift device often adopts a complex mechanism, which brings the disadvantages of high structure weight and low reliability. The hinge flap composed of pure rods improves these disadvantages with a small loss of aerodynamic performance. In this paper, a new type of hinge flap mechanism that can meet the needs of three-position design is studied. First, the calculation method of the mechanism parameters and the kinematics simulation are introduced. The guiding position of the mechanism is basically consistent with the aerodynamic design position, and the maximum error is less than 0.1 mm. Then, the mechanism parameters are optimized, including two aspects. The fairing size and the tangential load of the mechanism are optimized for the support part, and the inboard and outboard rotary actuators are optimized to maintain a linear relationship as much as possible with a maximum deviation of no more than 0.058 deg. Finally, the aerodynamic performance of the takeoff and landing configurations guided by the mechanism is evaluated.

Пекинская опера, как часть традиционной культуры КНР, имеет тысячелетнюю историю с момента своего развития. За этот период истории Пекинская опера стала важной формой художественного выражения в повседневной жизни населения Китая благодаря непрерывному развитию. Еще несколько десятилетий назад Министерство образования КНР признало важность наследования пекинской оперы. С развитием качественного образования содержание преподавания Пекинской оперы в музыкальных классах начальной школы Китая постепенно становится богаче, но в настоящее время влияние популярной музыки и зарубежной музыкальной культуры также вызвало дилемму в направлении развития пекинской оперы. Статья посвящена исследованию вопроса о важности сохранения наследия китайской традиционной оперы в музыкальном образовании КНР, сложностям использования китайской оперы на занятиях музыки в учебных заведениях Китая и способам их преодоления. Стоит выбрать несколько студентов, которые очень хотели попробовать, но не осмелились участвовать в конкурсе. После того, как несколько студентов возглавят демонстрацию, другие студенты, которые были заинтересованы, также могут присоединиться к конкурсу пекинской оперы. В конечном итоге у большинства учащихся может проснуться живой интерес к изучению музыкальной культуры родной страны.
Peking Opera, as part of the traditional culture of the PRC, has a thousand-year history since its development. During this period of history, Peking Opera has become an important form of artistic expression in the daily life of the Chinese people through continuous development. A few decades ago, the Chinese Ministry of Education recognized the importance of inheriting Peking Opera. With the development of quality education, the teaching content of Peking opera in China's elementary school music classes is gradually becoming richer, but at present, the influence of popular music and foreign musical culture has also caused a dilemma in the development direction of Peking opera. The article is devoted to the study of the importance of preserving the heritage of Chinese traditional opera in the musical education of the PRC, the difficulties of using Chinese opera in music classes in Chinese educational institutions and ways to overcome them. It is worth choosing a few students who really wanted to try, but did not dare to participate in the competition. After a few students lead the demonstration, other students who were interested can also join the Peking Opera Competition. Ultimately, most students may awaken a keen interest in studying the musical culture of their native country.

Применение интерактивных методов обучения оказывает положительное влияние на развитие навыков говорения на иностранном языке, в частности на английском. Авторы описали современные формы, принципы и методы организации интерактивного обучения коммуникативным навыкам на английском языке студентов-медиков. В данной статье дано рассмотрены основные методики интерактивного обучения навыкам говорения. Авторы определили сильные и слабые, с их точки зрения, стороны в применении интерактивных методов обучения студентов навыкам говорения. Было отмечено, что интерактивные занятия не просто способствуют повышению уровня знаний студентов по английскому языку, но и развивают их способности работать как самостоятельно, так и в команде, с нестандартным подходом к решению задач. Нами были определены оптимальные интерактивные технологии обучения студентов-медиков монологической и диалогической речи через посредство интерактивных технологий: технологии кооперативного обучения, технологии коллективно-группового обучения, дискуссионных технологий и моделирования. Технологии кооперативного обучения, применяемые на занятиях английского языка, подразумевают работу в малых группах, использования метода «Карусель». Данные технологии могут использоваться в учебных группах с разным уровнем знаний английского языка.
The use of interactive teaching methods has a positive impact on the development of speaking skills in a foreign language, in particular in English. The authors described modern forms, principles and methods of organizing interactive teaching of communication skills in English for medical students. This article describes the main methods of interactive teaching of speaking skills. The authors identified the strengths and weaknesses, from their point of view, of the use of interactive methods for teaching students the skills of speaking. It was noted that interactive classes not only contribute to increasing the level of students' knowledge of the English language, but also develop their ability to work both independently and in a team, with a non-standard approach to solving problems. We have identified the optimal interactive technologies for teaching medical students monologue and dialogic speech through interactive technologies: cooperative learning technologies, collective group learning technologies, discussion technologies and modeling. Cooperative learning technologies used in English classes involve working in small groups, using the Carousel method. These technologies can be used in educational groups with different levels of knowledge of the English language.

Objective. To study the impact of antibacterial therapy on level of proteolytic enzymes on example of the neutrophils elastase, and clinical course of an acute pancreatitis.
Materials and methods. There were investigated two groups of patients: in the main group (n=83) antibiotics were introduced by lymphotropic method, while in a control group (n=85) – in accordance to standard method. The content of the neutrophils elastase was determined in admittance day after 5 days of treatment.
Results. In admittance to hospital the enzyme level in patients of both groups did not differ. After 5 days of antibacterial therapy the neutrophils elastase quantity have been reduced more after conduction of lymphotropic therapy than after the standard one. Reduction of level of the neutrophil elastase «deflected» have promoted the reduction of the pancreonecrosis infectioning, leading to reduction in the operative interventions quantity performed in the main group of patients (lymphotropic antibacterial therapy) in 2.1 times as well as their reconvalescence.
Conclusion. Positive impact of lymphotropic antibacterial therapy towards «deflection» of proteolytic enzymes in the blood and on the acute pancreatitis course accordingly shows the reasons to recommend its application in this disease as an alternative to standard method.
