Solvent-free NMC electrodes for Li-ion batteries: unravelling the microstructure and formation of the PTFE nano-fibril network
Authors: Matthews Guillaume , Wheeler Sam , Ramírez-González Julia , Grant Patrick
Published: November 2023

The microstructure and electrochemical performance of solvent-free processed and slurry cast Li(Ni0.6Co0.2Mn0.2)O2 (NMC622) based electrodes for Li ion batteries has been investigated. In contrast to a moss-like PVDF-based carbon binder domain in slurry cast electrodes, the PTFE binder in solvent-free electrodes had a hierarchical morphology composed of primary fibrils of a few μm in diameter and 100's μm in length that branched into secondary and then ever finer fibrils, down to diameters of 10's nm or below. A mechanism for the formation of the branch-like morphology observed in PTFE-based solvent-free electrodes is also presented. Even the finest fibrils were confirmed to survive typical cathode cycling conditions. The solvent-free electrodes had progressively higher discharge capacities with increasing discharge rate, increasing to 150% at 2C compared with slurry cast equivalents, and capacity faded 40% slower over 200 cycles at C/3. Impedance analysis showed the solvent-free microstructure enabled reduced charge transfer resistance and ionic resistance, arising from minimal obscuration of the active material surface and no pore blockage.

Authors: Savoini Andrea , Gallagher Peter , Saady Abed , Maynard John , Tizzard Graham , Goldup Stephen
Published: November 2023

Mechanical geometric isomerism, which arises when bilaterally dissymmetric components are interlocked such that their internal mirror planes can be made congruent, is under-explored using simple prochiral components. Here we demonstrate that a single intercomponent H-bond appears sufficient to control the formation of rotaxanes and catenanes containing canonical mechanical geometric stereochemistry and identify a new mechanical stereogenic unit of rotaxanes, which yielded to a shuttling auxiliary synthesis.

Authors:   Medical Laboratory Technology Department, Erbil Health and Medical Technical College, Erbil Polytechnic University   , Iraq, K Ahmed Kharman , A Hawezy Aumed
Published: November 2023

Background: Urinary tract infections (UTIs) are the most popular type of diagnosed bacterial illness, and the most frequent cause of bacteria responsible for UTIs is Escherichia coli (E. coli). β-lactamases are the most frequent resistance for gram-negative bacteria to beta-lactam antibiotics, especially in E. coli. The number of patients infected by extended-spectrum β-lactamases (ESBLs) producing E. coli was rising and regarded as a significant global health problem. Objective: evaluate how frequently blaTEM, blaSHV, and blaCTX-M genes were detected in E. coli isolated from UTIs. Patients and Methods: We collected 54 midstream urine samples from patients with symptomatic UTIs, in all age groups, from the outpatient department in Erbil hospitals from October 1, 2021 to April 1, 2022 for the isolation of E. coli. All samples were analyzed for the detection of blaTEM, blaSHV, and blaCTX genes using the polymerase chain reaction (PCR) method. Results: Most of the samples were taken from females (61.11%); according to their ages, they were divided into two groups, and most of the samples (74.07%) were taken from patients below 40 years old. PCR testing for all ESBL-producing E. coli isolate samples revealed that 16S rRNA 797 was the most frequently detected gene in all analyzed samples (100%), while it was less frequently detected in blaCTX 585 (48.15%). Conclusion: Colonization with S. aureus and MRSA inversely correlated with younger This found that elevated ESBL genes in E. coli isolated from symptomatic UTIs in our community increase the risk of possible resistance. Keywords: Uropathogenic Escherichia coli, Urinary tract infections, blaTEM, blaSHV, blaCTX-M, PCR assay

В работе рассмотрен вариант обстоятельств, при которых атомная электростанция, работающая в переменном суточном графике нагрузки, получает сигнал о вероятном наступлении в ближайшее время экстремальных внешних воздействий, которые вынудят остановить реакторы. При этом персонал станции уполномочен установить режим, в котором реакторы будут работать в период угрозы до момента ее реализации или отмены. Приведен двухуровневый суточный график изменения мощности ядерного реактора. Считается, что предупреждение об угрозе поступает в начале периода, тогда на время угрозы экстремальных внешних воздействий мощность реактора устанавливается постоянной на уровне между дневным и ночным режимами. Поставлена и решена задача поиска оптимального уровня мощности, при этом функция потерь вычисляется как взвешенный вероятностями реализации и отмены угрозы суммарный экономический ущерб: из-за отступления от графика потребления в случае ложной тревоги; из-за простоя в йодной яме в случае совершившейся угрозы. Результаты работы позволяют сделать следующий вывод: при увеличении вероятности реализации угрозы растет эффект оптимизации, следовательно, следует изменить режим мощности до соответствующего уровня a. Приводятся оценки эффекта оптимизации.

Sir winston churchill as a pragmatist and the troop - Withdrawal at the dardanelles campaign – 1916
Authors: Gabrielle L. McBath
Published: November 2023

The following two-part essay will analyze critically four of the ten greatest controversies of Sir Winston Churchill's career that are based on the 2015 BBC News Magazine article of T. Heyden. Churchill, often referred to erroneously as an "opportunist", navigated his political career as a thorough pragmatist. The four controversies of his career are: a) Being “anti-union” during the Tonypandy Riots in 1910, b) Permitting the usage of “Mustard gas” against the Kurds and Afghans in 1919, c) Deploying the Royal Irish Constabulary Special Reserve (“Black and Tans”) in January 1919, and d) Indifference toward the Bengal famine in 1943. These examples were selected randomly to reflect a balance of two foreign and two domestic incidents. In the second part of this essay, Churchill was often referred to as a “political amateur”when he withdrew troops at the Dardanelles Campaign of 1916. However, the following four documents support otherwise that Churchill's assessment that the campaign in the Dardanelles was "not a civilian plan foisted by a political amateur upon reluctant officers and experts". These documents are entitled, 1. Excerpts from Churchill's Resignation Speech- 15 November 1915. 2) Excerpts from a letter from Churchill to A. B. Law (Head of the Conservative Party)- 21 May 1915. 3) Cabinet Memorandum by Churchill defending his Policy of the Dardanelles Campaign- 5 August 1915, and 4) Communique sent to Rear-Admiral J. de Robeck (of the Dardanelles Campaign)- 1917.

Authors: Tarik Aziz , Rabiul Islam
Published: November 2023

This study explores the processes and causes of occupational transformation in the fishing communities in coastal Bangladesh. Using a mixed-methods approach, data were collected from Raruli and Godaipur Unions in Paikgaccha Upazila, Khulna district, and Jalalpur Union in Tala Upazila, Satkhira district, through questionnaire surveys, Key Informant Interviews (KIIs), and Focus Group Discussions (FGDs). Findings show that coastal fishers, affected by various disasters, have been changing their fishing occupations and transitioning to other roles, such as fishing labor, fish business, shopkeeper, auto van puller, day laborer, construction worker, etc. The study also explores the causes of occupational transformation and finds that various factors, including different types of disasters such as cyclones, storm surges, riverbank erosion, salinity, flooding, etc., and other factors such as moneylender's business, decreased navigability of rivers, increased prices of fishing equipment, decreased fish populations in rivers and the sea, etc., compel them to make this transition. The study argues that occupational transformation in the fishing community will continue to increase if governmental and non-governmental organizations do not provide initiatives and alternative livelihoods in the coastal area.

Authors: Senthil Kumar C. , Bhavani C. , Harshini Priya S. R. , Jayalakshmi S.
Published: November 2023

This paper presents a novel approach to addressing the current water waste problem in conventional water tanks by implementing an efficient water monitoring and control system using Internet of Things (IoT) technology and Android applications. The existing water storage solutions often lack the ability to monitor and manage water levels, leading to significant water waste. In this research, an ultrasonic sensor is employed for precise water level measurement. The parameters critical to water quality, such as pH, Total Dissolved Solids (TDS), and turbidity, are also monitored and calculated. The microcontrollers process the sensor-derived data and transmit it to the internet through a Wi-Fi module (ESP 8266). Other existing technologies had certain drawbacks in some way, and the removal of these shortcomings and providing an efficient and economical solution has been the main focus of this paper. This paper outlines the development of a smart water tank system that not only reduces water wastage but also ensures water quality, thereby contributing to the sustainable management of water resources.

Authors: Sangay Jamba
Published: November 2023

This critical analysis delves into the allocation and utilization of public expenditure in education across all levels in Bhutan, including primary, secondary, and higher education. The study aims to provide valuable insights into how public funds are distributed and used within Bhutan's education system. By conducting this analysis, we seek to identify strengths, weaknesses, and areas for improvement in education funding and policy-making to enhance the overall effectiveness of public investment in education for the betterment of Bhutan's educational system and its citizens. The research employs a secondary data research method, allowing for an in-depth analysis of extensive datasets without the need for primary data collection. This method ensures efficiency and enables researchers to gain valuable insights into the education system and its funding. In 2015, public expenditure on education accounted for 25.5% of the total government expenditure in Bhutan. This marked a substantial increase from the previous year's figure of 17%. This is a positive trend that indicates a growing commitment to education. Expenditure in primary education increased significantly, rising from 32% in the previous year to 57% in 2015. This highlights the government's emphasis on foundational education, which is crucial for building a strong educational base. Expenditure per student in secondary education showed fluctuations, with a figure of 53.9% in 2014. However, there was an overall upward trend in expenditure per student from 1971 to 2014. This suggests that while secondary education is receiving attention, there may be room for more consistent funding. Tertiary education received 10.3% of the expenditure in 2014, although there were fluctuations in funding over the years. Ensuring adequate funding for tertiary education is crucial, as it plays a vital role in producing a skilled workforce that can contribute significantly to the nation's development. The analysis reveals that public spending on education as a percentage of GDP experienced fluctuations, with some years witnessing significant increases or decreases. Consistent education funding is vital for Bhutan's socioeconomic progress. This analysis emphasizes the need for stable investment in primary, secondary, and tertiary education. It highlights the evolving budget priorities and underscores education's critical role in Bhutan's development. Policymakers should use these findings toensuresustained and balanced education investment forlong-termprosperity.

Authors: Cardoso Claudia Andrea Lima , Caramao Elina Bastos , Castro Thiago Luis Aguayo de , Simionatto Euclesio
Published: November 2023

The leaves of Mangifera indica L. have been used in the medical system of India to treat diseases such as asthma, dysentery, cough, leucorrhea, jaundice, pain, and malaria. The analysis of different varieties of the same species is intended to determine if the compounds have a differential distribution. The present study investigates the volatile compounds from the leaves of two M. indica varieties extracted by hydrodistillation and analyzed by comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC�GC/TOFMS). The number of compounds identified by GC�GC/TOFMS was superior to that obtained by gas chromatography/mass spectrometry (GC/MS) for the same variety of M. indica. This study demonstrates the applicability of the GC�GC/TOFMS for the comprehensive profiling of essential oils from M. indica, in which 125 and 95 compounds were identified in the varieties �espada� and �cora��o de boi�, respectively. These results show that the compositions of the two analyzed essential oils present differences concerning the GC�GC/TOFMS and conventional chromatography technique, the GC/MS.

Modelling Flood Wave Propagation as a Result of Dam Piping Failure Using 2D-HEC-RAS
Authors: Mohamed Mahmood J. , Karim Ibtisam R. , Fattah Mohammed Y. , Al-Ansari Nadhir
Published: November 2023

In recent years, there has been a serious request for innovative, accurate approaches to be determined and controlled for dam failures. The present study aims to explore and evaluate the flood wave parameters that result from a dam break due to piping failure occurring in the body of the dam and routing the flood waves. Mosul Dam, which lies in the north of Iraq, and a reach of the Tigris River downstream the dam to Samarra Barrage at about 470 km are selected as a case study. A two-dimensional Hydrologic Engineering Center River Analysis System (2D HEC-RAS) and the Geographic Information System (GIS) have been supposed to be suitable for development calculations of the flood wave parameters based on the Digital Elevation Model (DEM) and land cover satellite images that enhance the calculations. The reservoir and two-dimensional flow area are delineated and incorporated with DEM. Manning`s coefficient for the whole area has been extracted according to the Land Cover satellite image, which showed that its value ranges between 0.025 to 0.037 with a correlation coefficient R2equal to 0.845 and 0.801 for the calibration and validation processes, respectively. The results of the scenario display a substantial performance of the maps produced from the model that represented the depth, velocity, and water surface elevation. All the maximum values of dam break parameters lie near the dam body and slightly decrease downstream. It is pre-eminent that the 2D HEC-RAS model is appropriate for analyzing and simulating the occurrence of dam breaches by visualizing the distribution of flood wave depth and velocities in two dimensions. Hence, the clear improvement in producing maps, which monitor the spread of hydrodynamic waves, gives an indication of risk areas that are threatened by inundation and aids in the formulation of emergency plans. Doi: 10.28991/CEJ-2023-09-10-010 Full Text: PDF
Parametric Analysis of Horizontal Static and Dynamic Behavior in Different Types of Masonry Structures
Authors: Xekalakis Georgios , Pitilakis Dimitris , Zuccaro Giulio , Christou Petros
Published: November 2023

This article introduces the "Pre-seismic Survey Form for Masonry" (PRISM), a simplified tool for evaluating masonry structures. It aims to be user-friendly for both experienced surveyors and beginners. The primary objective is to develop PRISM as an efficient means of gathering relevant data that influences the diverse behaviors exhibited by masonry structures, covering both structural and non-structural aspects. PRISM's development involves a parametric method for identifying critical parameters by analyzing drift results from the response spectrum and horizontal static analyses. These analyses are performed on common masonry structures in European Mediterranean nations. The study investigates various factors, including facade openings, materials around openings, wall thickness, ground type, ground acceleration (g), and principal structural material. By examining 300 2D models created in SAP2000, correlations in structural responses are established. The findings of the parametric analysis significantly enrich the qualitative and quantitative comprehension of structural responses. This advancement contributes to the contemporary knowledge of prevalent masonry structures within European Mediterranean regions. The PRISM survey form employs a numeric rating scale format. Notably, PRISM enables surveyors to access field results, minimizing reliance on computers quickly. The form's design also ensures accessibility and data reliability, making it universally applicable while maintaining simplicity. Doi: 10.28991/CEJ-2023-09-10-015 Full Text: PDF

Listening comprehension is an essential part of L2 learning. However, listening skills are neither taught nor assessed in the mainstream secondary and higher secondary public exams in Bangladesh. As a result, higher secondary students do not face a test of their listening skills until they attempt an IELTS test. For this reason, the listening test for the IELTS is challenging for post-higher secondary students. The purpose of this study is to explore the difficulties in the IELTS listening test perceived by Bangladeshi test takers; how test takers are prepared for the test and how experienced test takers report on the preparation for the test. Both qualitative and quantitative approaches have been adopted for the research. Semi-structured interviews were conducted with six IELTS preparatory-course trainers. In addition, five experienced IELTS test takers were also interviewed who scored a band score of 7.0 or above. All the participants were selected through purposive sampling. As a part of the quantitative research approach, 224 participants from the IELTS preparatory course were surveyed. The findings show that the primary challenge for the test takers is their inability to recognize known words as well as new vocabulary while listening to the audio in the IELTS test. The findings of the study may help IELTS trainers assist the potential test takers to deal with the difficulties of the IELTS listening test.

Riau is one of the susceptible regions in Indonesia, which faces frequent land and forest fires. Fires occur in various land covers and soil types, both peat and mineral soils, which emitted huge carbon to the atmosphere. Forest fires emit greenhouse gases, including carbon dioxide (CO2). The objective of the research was to quantify CO2 from land and forest fires. The quantification emission was for 2016 – 2018 based on the fire radiant power (FRP) dataset along with the buffer methodology for assessing fire-affected land extents across different land covers. The FRP dataset we used to be only at a confidence level of 70% or higher, which represents hotspots. The results revealed large numbers of FRP focal points (> 1000) that can be identified as fires for 2016 and 2018, whereas only small numbers (121) were identified for 2017. Then we quantified the area burned of 95,396 Ha in Riau for 2016, which was double to the 2018’s area burned. Further, this burning contributed to CO2 emission equal to 313,456 tCO2 for 2016. Emission in 2017 was a relatively low as not many observed fires detected.
EITHER/ OR, AND BEYOND

Reality and fiction build a binary which shared the fate of dualist thinking in general in the postmodernist age, dominated by deconstruction. The climactic point was probably reached by the fabrication of lens which magnify reality. The fabrication of virtual reality lens was meant to augment reality, virtual reality meaning less or a deformed reality show. Science and technology have thus reified the philosophical battle over positivist taxonomies and classifications that first came under the philosophical onslaught of Søren Kierkegaard and Friedrich Nietzsche. The “either/ or” dichotomy of the former ended up in the latter’s “beyond”, which, in quantum language, is a superposition of opposite states. Although the bulk of fantasy and science-fiction still capitalizes on the distinct ontologies of reality and fiction, the literature of late modernity (modernism and postmodernism) speculated on an ontological hybrid bridging the ontological gap between the two of them. Such are the modernist novel, “Isabel and the Devil’s Waters” by Mircea Eliade, and the postmodernist story, “Schrödinger’s Cat,” by Ursula K. Le Guin read in the key of an ontological poetics in the present paper.
ION POP RETEGANUL AS LITERARY HISTORIAN
Authors: COSTEA PASCU Alexandra
Published: November 2023

After 1848, the area inhabited by Romanians outside the Carpathian Arc underwent profound mental and social changes, which culminated in 1859 with the Little Union of Moldova and Wallachia. However, the consciousness of race and language were not realities that manifested themselves only in these Romanian provinces, Transylvania being united in national feeling with the other Romanians, despite the special historical conditions in which it is located. This consciousness of Romanianness would eventually lead to the Great Union in 1918 in Alba Iulia. One of the promoters of national consciousness was Ion Pop Reteganul, whose activity was also carried out in literary history, which he approached from a moderately critical perspective. His teacher training left its mark on his writing because he tried to bring out always in evidence the moralizing side of any text he brought to his reader. In its pages of historical-literary journalism, this moralizing side is doubled by the admiration for the personalities it presents, their activity, and their creation, which touched on topics necessary for the growth of a healthy Romanian community as a mentality and recognition of its value.

Kebutuhan kayu yang terus meningkat dan potensi hutan yang terus berkurang menuntut penggunaan kayu secara efisien dan bijaksana. Untuk mengatasi permasalahan tersebut diperlukan adanya alternatif pengganti kayu, salah satunya yaitu papan semen partikel. Limbah serbuk gergaji kayu kempas (Koompassia malaccensis Maing) sangat melipah, tetapi limbah serbuk gergaji kayu tersebut belum dimanfaatkan. Tujuan dari penelitian ini adalah untuk mengetahui: i.) pengaruh perbandingan partikel dengan semen,  ii.) pengaruh perbedaan tekanan kempa terhadap sifat fisika papan semen partikel serbuk gergaji kayu kempas dan iii.) interaksi antara perbandingan partikel dengan semen dan perbedaan tekanan kempa terhadap sifat fisika papan semen partikel serbuk gergaji kayu kempas  . Dalam penelitian ini model rancangan yang digunakan adalah rancangan acak lengkap faktorial dengan 2 faktor. Faktor pertama yaitu faktor perbandigan partikel (P) yang terdiri dari 3 aras yaitu P1 (1:3), P2 (1:4), dan P3 (1:5). Sedangkan faktor kedua yaitu perbedaan tekanan kempa (T) yang terdiri dari 2 aras yaitu T1 (25 kg/cm²) dan T2 (35 25 kg/cm²). Dari kombinasi kedua faktor tersebut terdapat 6 perlakuan yang diulang sebanyak 3 kali, sehingga terdapat 18 sampel pengujian).  Hasil penelitian ini menunjukkan bahwa perbandingan semen dan partikel hanya berpengaruh terhadap kerapatan pada tingkat signifikansi 0,05, namun tidak berpengaruh terhadap kadar air dan pengembangan tebal papan semen partikel serbuk gergaji kayu kempas.   Perbedaan tekanan kempa tidak berpengaruh terhadap seluruh sifat sifat fisika (kerapatan, kadar air dan pengembangan tebal) papan semen partikel serbuk gergaji kayu kempas. Adapun interaksi perbandingan semen dengan partikel dan perbedaan tekanan kempa juga tidak berpengaruh nyata terhadap seluruh sifat sifat fisika (kerapatan, kadar air dan pengembangan tebal) papan semen partikel serbuk gergaji kayu kempas.

The wide-spread use of a host of varieties is a striking feature of paddy cultivation in the Malabar district. The practice has probably been found necessary because of the absence of regular irrigation systems, the peculiar distribution of rainfall and the uneven contour of the land. As regards the requirements of the soil and the limitations of water supply every ryot seems to know his lands so intimately that the different varieties are perhaps chosen only to reduce the local irregularities of soil and water supply. The multiplicity of varieties may therefore be taken as an index of the diverse conditions of paddy cultivation prevalent in the locality. Besides this, the type of land and land tenure, resistance to pests and diseases, season and rainfall, the demands of the markets and the mills, also exert a powerful influence on the choice of varieties that are grown. In 1938-39 Palghat taluk raised 207,445 acres of paddy, which represents 71'2 per cent of the annual cultivated area. Farming in the taluk is practically confined to the cultivation of rice in wet lands.
