Authors:   Northeast Ohio Medical University, Otchere Phoebe , Seif Christian ,   Northeast Ohio Medical University, Myers Joseph ,   Summa Health,   Northeast Ohio Medical University
Published: September 2022

Introduction. The Cardiobacterium species is a pleomorphic Gram-negative bacterium discovered in 1964 and is part of the HACEK (Haemophilus, Aggregatibacter, Cardiobacterium, Eikenella, and Kingella) group of organisms known to cause endocarditis. It has low virulence and can also cause dacryocystitis, septicemia and abdominal abscess. We report a patient with C. hominis prosthetic joint infection in the absence of definitive endocarditis. Case Report. A 57-year-old man presented to his orthopedic surgeon 17 months after left total knee arthroplasty with a 4–5-day history of left knee pain following yard work. He had an aortic valve replacement in 2003, mitral valve repair in 2006 and bovine aortic valve replacement in 2019 (12 months previously). Aspirate of knee joint fluid was grossly cloudy. Two of two preoperative blood cultures revealed Cardiobacterium species after 4 days’ incubation. He was initially treated with intravenous vancomycin plus piperacillin/tazobactam followed by 6 weeks of parenteral ceftriaxone followed by five months of oral cefdinir. Patient is infection-free 6 months after completion of antimicrobial therapy. Discussion. Cardiobacterium hominis is a slow-growing, fastidious, capnophilic, Gram-negative bacillus commonly found in normal oral and upper respiratory flora. Google Scholar™ and PubMed®searches were conducted and this is the first reported case of prosthetic joint infection due to Cardiobacterium hominis. We found three previously reported cases of C. hominis pyogenic arthritis: one patient with native knee pyogenic arthritis, one patient with cervical spondylodiscitis and one patient with lumbar spondylodiscitis and epidural abscess. Two of these three patients had TEE-documented infective endocarditis and one had a bioprosthetic aortic valve without evident vegetation on TEE. Our patient had a bioprosthetic aortic valve without TEE evidence of endocarditis. C. hominis should be added to the list of organisms that can cause bacteremically spread prosthetic joint infection.

Authors:   School of Mechanical, Aerospace, and Maritime Engineering, Amirkabir University of Technology (Tehran Polytechnic), No. 350, Hafez Ave, Tehran, Iran, Sheykhbaglou Soroush
Published: September 2022

This study investigates the dynamics and properties of non-premixed methane/air flames under three swirl numbers by segmenting flame images using the Otsu thresholding technique. Under three operating conditions, the lean blow out (LBO) and flame length, lift-off height, maximum width, flame angle, and flame pulsing displacements in terms of flame center of gravity, length, and width are measured and compared. A high-speed camera is used to record video of flames, and the image processing of frames collected from a high-speed video was accomplished by using the intermittency distribution method to quantitatively compare flame attributes. The findings show that increasing the swirl number from 0.5 to 0.7 generally has an unfavorable effect on the LBO at given fuel flow rates, and the LBO of flames under 35° (0.6 swirl number) and 40° (0.7 swirl number) swirlers has decreased up to about 15% and 40%, respectively when compared with a 30° swirler (0.5 swirl number). Additionally, observations indicate that the flame length (𝐿) and lift-off height (𝐿𝑂) drop as the swirl number rises, although the flame width (𝑊) and angle (𝛼) show an ascending tendency. Besides, flame lift-off reveals an increasing-decreasing trend with an increment in the airflow, and flame length decreases as the airflow rate increases. It was also observed that flame pulsating displacements in terms of center of gravity (𝛿𝐶𝐺), length (𝛿𝐿), and width (𝛿𝑊) increases with an increase in the fuel flow rate, and as the swirl number is increased, 𝛿𝐶𝐺 and 𝛿𝐿 lessens, while 𝛿𝑊 increases.

Published: September 2022

Rotaxanes are known for the mechanically interlocked molecules for decades. The present work demonstrates a method to prepare multi-responsive rotaxane by conjugating with a multi-responsive supramolecule. Benzoxazine dimers, N, N’-bis(3,5-dimethyl-2-hydroxybenzyl) methylamine derivatives, are good models because their simple chemistry. An azobenzene containing benzoxazine with remaining hydroxyl group for further conjugation with rotaxane was designed. The ring opening of rotaxane using fluorescent phenol provides benzoxazine dimer with metal ion responsive and fluorescent properties. Based on this concept, light responsive benzoxazine conjugated with rotaxane system shows light, metal ion and rotaxane shuttling responsiveness which can be followed by fluorescent signals. The present work shows simple way to develop rotaxanes with multi-responsive functions using supramolecular chemistry of benzoxazine dimer prepared from light responsive phenol.

Authors: AWONIYI Aderinola J. , ABIDAKUN Oreoluwa M. , OLADIJI Adenike T.
Published: September 2022

Micronutrients are vitamins and minerals needed by the body in minute amount and whose impact on the body’s health is vital. Hence, deficiency in any one of them could cause severe and even life-threatening conditions. Deficiency in iron is the most common micronutrient deficiency and is prevalent in children and pregnant women. The infused extracts of Parquetina nigrescens (PN) leaf were used in the management of iron deficiency in weanling rats to provide a food-based approach strategy that is readily accessible, affordable, and acceptable to the low-income population who are more susceptible to micronutrient deficiencies. Diet-induced iron-deficient weanling rats (55.0 ± 10.0) g was administered infused extracts (PN, PN+ ginger PN+ lemongrass, PN+ milk) of PN at 1000 mg/kg body weight for 28 days. The haemoglobin concentration of rats administered PN extract was significantly (p < 0.05) increased compared to the control. Serum protein assay indicated administration of PN extract reduced significantly (p < 0.05) concentrations of Divalent Metal Transporter 1, transferrin, ferroportin, and increased hepcidin and ferritin concentrations. Higher concentrations of flavonoids in the PN extract are proposed to support its haematopoietic activity alongside its ascorbic acid content. The infused extract of PN showed better haematopoietic activity when taken alone than when additives were added.

Published: September 2022

The limitations to the promotion of the profession in Nigeria were examined, along with the utilization and efficacy of the existing marketing techniques, the professional-client connection, and the least used strategy, which was promotion through specialized websites. The results of this study indicate that senior secondary school students in Ondo State have a high level of awareness of the quantity surveying profession. The quantity surveying profession should be aware of the advantages of marketing strategies and should permit the use of specialized websites as marketing strategies within the bounds of professional ethics. The Nigerian Institute of Quantity Surveyors (NIQS) and the Quantity Surveyors Registration Board of Nigeria (QSRBN) should take greater initiative to inform secondary school students about the career of quantity surveying, particularly via the utilization of State Chapters.

Цель исследования – определить аминокислотный состав белка семян различных сортов льна масличного и сравнить его с белками жмыхов наиболее распространенных масличных культур, используемых в животноводстве Свердловской области. Семена трех сортов льна масличного: Уральский, Уральский желтый и ЛМ 98 выращены на серых лесных почвах опытного поля Уральского НИИСХ. Средние пробы жмыхов масличных культур отобраны в сельскохозяйственных предприятиях Свердловской области по методике, используемой при зоотехническом анализе кормов. Аминокислотный состав изучаемых образцов выполнен методом высокоэффективной жидкостной хроматографии. В семенах изучаемых сортов льна масличного, выращенных в условиях Свердловской области, содержатся все незаменимые аминокислоты. Результаты исследований подтвердили сведения научной литературы, указывающие, что по биологической ценности белок семян льна масличного приближается к идеальному белку по рекомендациям ВОЗ и идеальному белку для рационов свиней. В 100 г белка семян льна содержится 7,5–8,5 г лизина; 6,7–7,2 г метионина и цистина; 11,3–12,3 г фенилаланина и тирозина; 3,5–6,1 г триптофана. Семена льна масличного и льняной жмых можно с успехом использовать для балансирования рационов сельскохозяйственных животных по аминокислотному составу. Установлены различия между сортами льна масличного по содержанию в семенах лизина, метионина, фенилаланина и триптофана. Сравнительно мало в семенах масличного льна лимитирующей аминокислоты треонина, что является характерным для белка других масличных культур, жмыхи которых используются в сельскохозяйственных предприятиях. Аминокислотный состав белка семян следует учитывать при создании новых сортов льна масличного.

Authors: Шепелёв Сергей Дмитриевич , Пятаев Максим Вячеславович , Зырянов Антон Павлович , Шалонкина Евгения Владимировна
Published: September 2022

Бороны с зубопружинными рабочими органами являются достаточно универсальным типом машин, поскольку могут решать широкий спектр задач в разнообразных условиях эксплуатации. Значительно повысить качество обработки почвы пружинной бороной позволяет использование параллелограммных подвесок в креплении секций к продольным поддержкам рамы. Данный способ крепления позволяет добиться лучшего копирования неровностей поверхности почвы рабочими органами бороны и значительно расширить диапазоны технологических регулировок. При лучшем копировании микрорельефа обеспечивается одинаковый характер взаимодействия пружинных зубьев, расположенных на разных рядах секции, с поверхностью почвы, что создает предпосылки для повышения равномерности глубины обработки. Вопрос повышения качества поверхностной обработки почвы за счет обеспечения рациональных конструктивных и эксплуатационных параметров актуален. Процесс работы секции бороны смоделирован на основе уравнения Лагранжа второго рода. Получено уравнение движения рабочей секции пружинной бороны с параллелограммной подвеской. На основании численного решения полученного уравнения выявлено, что добиться необходимой амплитуды отклонений рабочей секции бороны с параллелограммной подвеской возможно за счет подбора рациональных конструктивных и эксплуатационных параметров. Установлено значительное влияние на амплитуду отклонений секции при взаимодействии ее рабочих органов с почвой угла установки наклонных тяг параллелограммной подвески и их длины. Значительно влияет на амплитуду отклонений секции место крепления блока компенсирующих пружин к наклонным тягам параллелограммных подвесок. Использование блока компенсирующих пружин с возможностью регулирования усилия поджатия позволяет значительно расширить диапазон технологических регулировок пружинной бороны.

Представлены результаты кинетических исследований экстракции каротиноидов и их отдельных групп из бурой водоросли Дальневосточного региона S.miyabei. Кинетика извлечения каротиноидов и их групп из бурой водоросли S.miyabei определяется используемым экстрагентом и методом экстракции. В качестве экстрагентов использованы 70 %-й раствор этанола и 50 %-й раствор глицерина. Экспериментально доказано, что раствор 50 %-й глицерина является более эффективным экстрагентом для каротиноидов, каротинов и ксантофиллов из бурой водоросли S.miyabei, чем раствор 70 %-й этанола – после 11 часов экстракции методом мацерации концентрация каротиноидов увеличивается в 4,05 раза, что на 30,6 % больше, чем при экстракции 70 %-й этиловым спиртом. Аналогичная зависимость наблюдается для экстракции каротинов: содержание увеличивается в 3,1 раза, что на 34,8 % больше, чем при экстракции 70 %-м этиловым спиртом. Однако экстракция ксантофиллов демонстрирует обратную зависимость: содержание при экстракции глицерином на 21 % ниже, чем при экстракции 70 %-м этиловым спиртом. В экстрактах определено существенно более высокое содержание ксантофиллов в сравнении с каротинами. Рациональное время процесса экстрагирования составило 7–11 часов в зависимости от способа экстракции.

Published: September 2022

In this seventh article of the 19th Midwifery Basics series on humanising birth, the authors discuss the importance of using critical pedagogy as a pathway to transforming maternity care and humanising childbirth. We have a responsibility to students in terms of what and how we teach future generations of midwives. Midwives are guardians of normal birth, and they are also teachers, passing on midwifery technology (knowledge of the art and skill of midwifery) to midwifery students. Midwifery academics in particular, as educators and researchers, are guardians of the discipline and its knowledge base. The authors of this paper, all of whom work in higher education, see education as transformational – transformational on a personal level, as well as encompassing the transformation from student to midwife, the transformation of the profession itself and, ultimately, the transformation of society.
Has Fiscal Decentralization Promoted or Restricted Public Environmental Expenditure ?
Authors: Liu Wei , Li Jiaying , Xu Ting
Published: September 2022

Public environmental expenditures are the crucial means to achieve ecological protection and environmental governance, while fiscal decentralization system is the key factor which affects the preferences of expenditures by local government. In order to further identify whether fiscal decentralization has negative incentives for the behavior of public environmental governance by local government, this paper applies provincial panel data of China from 2007 to 2015, to explore the effect of Chinese-styled fiscal decentralization on public environmental expenditures from the two dimensions of income and expenditure decentralization. The research results show that both income and expenditure decentralization have significant negative correlations with public environmental expenditures, which confirms that current fiscal decentralization system has strong incentive distortions and insufficient constraints on the behavior of public environmental governance by local government. Therefore, in order to promote green development and build a beautiful China, improvements should be made in terms of institutional environment, the relationship of financial authority and powers between central and local government, transfer payment systems, the governance models of regional linkage and collaboration, and environmental protection concepts, etc.

Authors: Fu Yuanxian , Liao Xianxin , Peng Hui , Jiang Lin , Li Ye
Published: September 2022

The Belt and Road Initiative is the Chinese approach to improving global governance. Based on country-level panel data, the paper analyzes the promoting effect of the Belt and Road Initiative on the governance of countries along the route by using difference in difference method. First, our study finds that the implementation of the Belt and Road Initiative has significantly improved the governance level of the countries along the route, and this finding remains robust after a series of tests. Second, the mechanism study finds that the Belt and Road Initiative improves governance in Belt and Road countries by influencing Chinese outward foreign direct investment (FDI) and Internet penetration in the countries along the route. Finally, the moderating effect suggests that the Belt and Road Initiative has a more significant impact on governance in countries that are closer to China and receive more official development assistance. Further heterogeneity analysis reveals that the governance promotion effect of the policy is more pronounced for countries with lower levels of economic development, population density, merchandise trade, and FDI.

This study with a view to explore the influencing factors of user stickiness of booking tourism applications’ users. Conducting surveys on samples from China online, this study analyzes the impact of different levels of user experience value, user satisfaction, and perceived risk on user stickiness by using SPSS 23.0 and AMOS 23.0.Results of correlation analysis and structural equation modeling indicate that both functional experience value and user satisfaction significantly positive influence user stickiness, while neither emotional experience value nor perceived risk have significant impact on user stickiness. In addition, user satisfaction is found an important mediator in the relationship between experience value and user stickiness. In exploring the moderating effect of perceived risk, results find that as perceived risk deepens, both the positive impacts of functional experience value and emotional experience value on user satisfaction are weaken, and the positive influence of functional experience value on user stickiness is decline.
Fiscal Decentralisation, Economic Development, and Carbon Emissions: Empirical Analysis Based on the Provincial Static and Dynamic Panel Data
Authors: Chen Yilong
Published: September 2022

The target 'Carbon Peak' and 'Carbon Neutral' in China is a key strategic choice to promote environmental regulation and high-quality economic growth. Public finance, as the bedrock and pillar of national governance, has a significant influence on China's macroeconomics and policy execution. This paper selects provincial panel data of China from 2010 to 2019, together with a two-way fixed-effect model and a Difference-GMM model, in order to conduct an empirical analysis of the impact of fiscal decentralisation and economic development on carbon emissions. The findings reveal that fiscal decentralisation has a considerable positive impact on carbon emissions, and that economic development and carbon emissions have an inverted U-shaped connection. Furthermore, economic development may reduce fiscal decentralisation's contribution to carbon emissions. In addition, there is a dynamic lag impact associated with carbon emissions. As a result, to achieve green and low-carbon transformation in China, advanced and long-term planning is required, as well as the optimisation of local government evaluation mechanisms and the application of fiscal funds.

On the Deviating Effect of the English Translations of Rhetorical Movie Lines --- A Case Study of Hi, Mom
Authors: Lei Suxia , Li You
Published: September 2022

Lines are considered the main means used by scriptwriters to show plots, depict characters and embody themes. Various figures of speech are employed in lines to enhance their expressiveness and functions by deviating from zero degree as a base point. Taking the movie Hi, Mom, this paper analyzes the deviating effect of the English translations of rhetorical lines at the four levels of morphology, syntax, semantics and logic. According to the analysis, the use of figures of speech in these English lines can achieve the same deviating effect as that of rhetorical Chinese lines; on the other hand, the original deviating effect will be absent from the translations without the application of rhetorical means. Therefore, it is better for translators to adopt rhetorical devices when translating rhetorical lines, which will play a vital role in the success of movies in overseas markets.
