Authors: Raei Yaghoub , Ghahremani Roghaye , Ghassemi Saeid , Shafagh-Kolvanagh Jalil
Published: July 2022

Intercropping and biofertilizers application are the most important agricultural methods for moving towards minimizing the risks of agricultural production and increasing production efficiency. Consequently, this experiment was conducted at one year and in 2019. A factorial set of treatments was arranged within randomized complete block design (RCBD) with three replications to investigate the effect of different planting ratios with safflower and soybean (sole cropping, 30:100 soybean to safflower ratio, 60:100 soybean to safflower ratio and 90:100 soybean to safflower ratio) and nutrient levels (100% urea fertilizer, 100% biofertilizer and the combined application of urea and biofertilizer) on growth and yield of these crops. The results of this study indicated that intercropping patterns had the highest plant height, number of grains per plant, biological and grain yields. In addition, the means of the number of heads per plant and the number of grains per head in safflower and the weight of 1000 grains in soybean were increased as intercrops were grown. Maximum of grain number per plant in safflower, leaf number per plan in soybean and biological and grain yields in both crops were attained in urea + biofertilizer. In all of intercropping patterns the values of LER (land equivalent ratio), RVT (relative value total) and RCC (relative crowding coefficient) was more than one, indicating an advantage from intercropping over sole crops.

Authors: Emanuel Federica
Published: July 2022

The paper reflects on the topic of learning outcomes in Higher Education. The emphasis on the education process and learning benefits students, faculty, and institution. The theme of learning outcomes in relation to instructional design and assessment becomes the subject of faculty development programs; a three-level training is hypothesized and discussed, starting with the IRIDI training program for faculties at the University of Turin. The first level is the exploration of learning outcomes’ topic, which can start from the syllabus development. The second level refers to the reinforcement of the use of learning outcomes in the didactic and assessment practices. The last level emphasizes the importance of providing faculty with specific training, with a collegial and institutional focus. This training model will be able to support and promote student-centered, inclusive, and quality teaching in Higher Education.

Designing an Appalachian forest path through walking
Authors: Heavers Nathan
Published: July 2022

Contemporary walking paths are often composed of static surfaces, limiting pedestrians to prescribed routes. Piazzas and streets allow for wandering, but are likewise inert; one’s passage leaves no trace. A forest path, branching from a well-used hiking trail in the Appalachian Mountains records the passage of time through the pressure of the walker’s feet on leaves and soil. Negotiating topography and vegetation, fallen trees become thresholds and standing trees mark portals as the pedestrian wanders through rooms framed by living columns. On most days, the walker retraces the path, solidifying the route, but occasionally the walk branches freely. The forest path is a co-design, evolving by the action of walking and myriad life processes in the woods. Drawn on the earth by walking, a literal route has become the author’s figurative path, stimulating an imaginative drawing practice.
Geografie lente. Percorrere le strade di Atene per educare lo sguardo
Authors: Carlini Alessandra
Published: July 2022

The essay deals with an investigation into the narrative capacity of the landscape as a palimpsest experienced through movement and gaze. The opportunity to reflect on the cognitive potential of ‘traveling’ and ‘staying’, of a geography capable of making the authentic relationships between the form of the soil and the anthropic form eloquent, is offered by reading the project by Dimitris Pikionis in Athens (1954-1958) to respond to building pressure that risked compromising the in- tegrity of the areas around the Acropolis. It is the essay Aesthetic Topography (1935) that outlines the theoretical framework that guides Pikionis’ work in these places, suggesting to contemporary architectural culture, a wealth of experiences useful for regaining an embodied knowledge, a les- son on how to educate the gaze to interrogate sensitive reality.
Apprendere camminando in paesaggi in contrazione tra Biella e Ivrea
Authors: Mareggi Marco , Ghebregzabher Sara , Lombardini Agnese , Marchesi Irene
Published: July 2022

Through summer schools, the Laboratorio del cammino proposes a learning method based on the direct and slow experience of walking. After a period in which the pandemic prevented teaching in presence, this approach was considered even more valuable. It combines and does not replace a digital experience with one of proximity, making it possible to compare what is visible when crossing a territory with what is seen from afar. The article reports the participation in the 2021 edition of the summer school, focused on the industrial and territorial contraction of north-eastern Pied- mont. Moving around and staying in the area made it possible to reveal an articulation of open spaces that make up the countryside, which is thus highlighted concerning an image obscured by the factory. Themes and problems of agricultural and silvo-pastoral shrinkage emerge, and initiatives take care of the territory.
Giornate internazionali di studio sul paesaggio 2021 e 2022. Percepire il co-divenire incarnando alterità
Authors: Antoniolli Elena
Published: July 2022

La recensione propone una prospettiva critica della diciassettesima edizione delle Giornate Internazionali di Studio sul Paesaggio organizzata da Fondazione Benetton Studi Ricerche incentrata sul rapporto tra corpi e paesaggi. Come partecipa la nostra adesione corporea al paesaggio? Qual è la misura dell’interazione sensoriale con esso? Come si evolve il rapporto tra corpo e paesaggio nell’Antropocene? Attraverso queste domande si articola la riflessione tra realtà percepita e corporeità, tra esperienza sensoriale e immaginario mitopoietico, in un connubio tra arte, antropologia, storia dell'arte dei giardini, cultura del paesaggio e danza. Ripercorrendo i ragionamenti dei dieci contributi che hanno nutrito il convegno, emergono affinità tematiche tra “essere” nel paesaggio e “sentire” il paesaggio.

Il coinvolgimento attivo e percettivo del corpo avviene grazie un’immersione reale nel paesaggio, ma anche attraverso la sua dimensione narrativa. Il corpo, specchio della paesaggio, muta nella sua fisicità e nella sua condizione psichica, richiamando un processo di metamorfosi reciproca e al contempo un approccio psicogeografico, in cui l’erranza ci invita ad accogliere l’Altro e l’ibridazione del paesaggio, secondo un neo-animismo del “sentire”.

Introduction: sex workers are configured as a historically marginalized group for deviate of the moral and social behavior pattern dictated by conservative dogmas on which Brazil was built. Such exclusion is also expressed in public health policies, where the group is mentioned only in actions and programs aimed at sexually transmitted infections (STIs), which violates basic principles proposed by SUS (Brazilian Unified Health System). This paper aims to analyze the care received in the context of health care from the perspective of sex workers.
Methods: this is a descriptive and exploratory study, with a qualitative approach, that have as referential of analysis the Collective Subject Discourse (CSD), built from a half-structured interview realized with the group in question and a socioeconomic questionnaire. The DSC is a method that assemble opinions and individual expressions in a unique testimony, written in first person singular, that gives voice to this collectivity. The collect was helped by community health agents of Family Health Unit that includes the brothel’s territory.
Results and Discussion: were interviewed 22 sex workers, being 19 cis woman and 3 trans woman, most of whom in a situation of social vulnerability – brown or black, little schooling and low rent. The speeches identified the existence of health care that does not meet the specific demands of this population, in addition to the presence of fragmented care and focused on sexual and gynecological health. The trans or cis interviewed, moreover, strong resistance to gender identity and respect for the social name by the team. In addition, there were expressions of fear in revealing the profession during medical appointment, due to the stigma and preconception that fell on them. Even so, these professionals understand that their health needs are met in SUS, which connotes a resigned view of the gaps in the care network, requiring specific health actions, programs and policies for this population.
Final Considerations: the sex workers are a society’s cutout that suffer daily with stigma on their pattern of sexual behavior, living an important condition of social vulnerability. This reflects on fear to seek medical services and to reveal their profession, resulting in gaps on the access and right to health in this population. It is necessary, therefore, creation of health programs and policies specifics and requalification of the health teams for the management of this patients.

Introduction: in 2019, the proliferation of a virus identified as SARS-CoV-2 emerged in the city of Wuhan, a district in China, quickly spread throughout the world, gaining pandemic status and less than 1 year, its repercussions and magnitude caused scientists, governments and society to adopt severe measures to combat this disease.
Objective: to analyze mortality, incidence and mortality from COVID-19 in the municipalities of Botucatu and Serrana, São Paulo, Brazil.
Methods: this is an ecological study with a time series design with secondary data. All registered cases and deaths registered by COVID-19 from April 2020 to August 2021 in the municipalities of Botucatu and Serrana, São Paulo, Brazil were considered. The incidence, mortality and lethality rate were used. The monthly and/or weekly percentage variation and their respective 95% confidence intervals were estimated.
Results: it identified that 12.88% of the residents of the city of Botucatu were infected with COVID-19 and 8.61% of the population of the municipality of Serrana was infected. There was a stationary trend of mortality and incidence in the period between April 2020 and May 2021 and decreasing in both sexes in the mortality rate in the municipality of Serrana, in the city of Botucatu there was a trend of increasing mortality and incidence in the same period observed.
Conclusion: The mass vaccination strategy of citizens in the cities of Botucatu and Serrana present robust data to consider that immunization has a decreasing effect on the number of cases and deaths from COVID-19, which effectively contributes to fighting the pandemic and reduces the contamination and progression of the disease to more severe cases.

Introduction: the public health crisis caused by COVID-19, a disease caused by SARS-CoV-2, has imposed physical threats and psychological suffering on both infected patients and individuals who experience social isolation and various governmental restrictions, leading to the appearance of symptoms like anxiety, depression, as well as insomnia, stress, and changes in biological rhythm. In face of this stressful scenario, interventions based on mindfulness (MBIs) have proved to be potentially adequate tools in reducing psychological suffering and generating well-being in the general population.
Objective: to describe the effects of mindfulness-based interventions during the COVID-19 pandemic.
Methods: A systematic literature review was conducted on the effects of mindfulness intervention in times of COVID-19. The articles were searched in four databases (Pubmed, Embase, Scopus, and Science direct) and the PRISMA protocol was used to conduct this review. In total, fourteen articles were included in the study.
Results: the use of mindfulness techniques in the population with impaired mental health because of the COVID-19 pandemic proved to be beneficial, with improvement in emotional stress scores and reduction in anxiety symptoms, through formal mindfulness meditation practices such as mindful breathing, body scanning, and application of the mindfulness-based stress reduction strategy (MBSR). Strategies were also applied through smartphone applications that had the objective of promoting the increase of mindfulness and the development of the acceptance without judgment of the traumatic experiences already lived, in addition to an integrated intervention on the internet with the use of mindfulness, the training of respiratory relaxation, refuge skills and Butterfly Hug Method.
Conclusion: with the pandemic going through, still with high mortality, continuity of social isolation, and, consequently, intensification of psychic suffering in the population and health professionals, interventions based on mindfulness (MBIs) are being effective to reduce this suffering, prevent the appearance of of chronic mental disorders and promote positive impacts on physical and mental well-being.
Intravitrealversus Posterior Subtenon Triamcinolone Acetonide in Conjunction with Intravitreal Bevacizumab for Refractory Diabetic Macular Edema
Authors: Gull Ambreen , Khan Niazi Fuad Ahmad , Raza Ali
Published: July 2022

Purpose

Aim of this study was to evaluate and compare the effects of combined simultaneous injection of intravitreal triamcinolone acetonide and bevacizumab versus intravitreal bevacizumab and posterior subtenon triamcinolone acetonide in treatment of persistent refractory diabetic macular edema after intravitreal bevacizumab injection failure

Methods

40 pseudophakic diabetic patients were enrolled in quasi experimental study conducted at ophthalmology department. All eyes were specifically diagnosed with persistent refractory diabetic macular edema with central retinal thickness of _____on OCT. Patients were divided into two groups. Group A was given simultaneous injection of intravitreal bevacizumab 1.25mg/0.05ml with posterior subtenon triamcinolone 40mg and group B was given intravitreal bevacizumab in conjunction with simultaneous intravitreal triamcinolone 2mg/0.05 ml.Patients were followed upmonthly till three months. Changes in the best corrected visual acuity, intraocular pressure and central retinal thickness by optical coherence tomography were evaluated in both groups. Retreatment was given at 12 weeks interval whenever indicated by OCT.

Results

Group B showed a more significant decrease in the median CRT at 1month (p =0.0002)but after 3 months both groups showed a reduction in CRT which was not statistically significant between two groups _____. Both groups had significant improvement in BCVA compared to pre-injection baseline visual acuity.Between two groups BCVA changes were not statistically significant at 3 months _____.Five eyes in group B developed IOP beyond 22mmHg, which was treated with anti glaucoma medications within 2 weeks. No eye in group A developed IOP greater than 21mmHg. At 12 weeks, 7 of group A patients and 6 of group B patients developed recurrent macular edema and required repeated injections.

Conclusion

While treating persistent refractory diabetic macular edema, posterior subtenon triamcinolone is as effective as intravitreal triamcinolone in conjunction with intravitreal bevacizumab in reducing CRT and improving and stabilizing BCVA but in terms of IOP rise posterior subtenon injection is safer as compared to intravitreal injection. Both treatments are cost effective and combined simultaneous injections decrease the number of repeated injections.
Elaboration of Popular Science Texts on COVID-19 in Higher Education Chemistry: Content Analysis in Focus
Authors:   Instituto de Química de São Carlos, Universidade de São Paulo, Brasil, Sotério Carolina , Queiroz Salete Linhares
Published: July 2022

Introduction: The importance of public communication of science and technology (PCST) became evident in the face of the COVID-19 pandemic, which brought scientists closer to popular media in an unprecedented way. However, the training of these professionals to communicate with non-specialist audiences is still incipient. Thinking about contributing to initiatives that aim to meet this need, an environment of a PST magazine was simulated in which chemistry bachelor students, in the role of science journalists, were invited to write popular science texts (PST) on COVID-19. Goals: This work aims to analyze the textual content produced by students, highlighting the strengths and weaknesses of PST. Methods: To this end, the foundations of Content Analysis (CA) were used, which allowed the characterization of PST from the perspective of recurrent elements in this type of production. From this perspective, the material analyzed was submitted to a five-step process: (i) preparation of information; (ii) transformation of content into units of analysis; (iii) categorization of the material, which emerged from a PST Analytical Framework; (iv) description of the categories; (v) and interpretation of results. Results: The students used visual and textual resources to appeal to the reader's attention; showed concern with the contextualization of information; and dissemination of an undistorted view of scientific production, from the detailing of the characteristics of scientific activity. It was also shown that PST with less use of linguistic features can result in more conceptual and technical approaches. Conclusions: This experience corroborated the students' potential to promote information about science to lay audiences, as they are close to both the non-specialized public and the academic community; and reinforced the applicability of CA to relate analytical categories of PST reported in the literature to more particular cases, such as the one described here.
Automation of organizations using cloud technologies: security issues
Authors: Zalialetdzinau K.
Published: July 2022

The article reveals the principles of automation of organizations using cloud technologies through the prism without the peak aspect. The main stages of development of cloud technologies are characterized, the advantages of using these systems in everyday work are revealed (low consumption of financial resources, possibility of universal access to information, constant improvement of software and technologies). At the same time, attention is drawn to the main challenges facing users of cloud services: the need for a constant and uninterrupted Internet, the inability to recover information in case of loss. Security remains a major issue, therefore. The purpose of the article is to analyze the risks and possible ways to overcome them in the work of organizations with cloud technologies. It is established that the system that affects the reliable storage of information from customers can be exposed to such threats as cross-site-scripting, fishing, Trojans, viruses. This is due to the fact that, as a rule, consumers working with the cloud computing service, use an Internet browser. In order to optimize information security at this level, you need to use licensed anti-virus software packages, personal firewall tools, tools to encrypt data or information on disk, a properly configured Internet browser. It is proved that the security of virtualization mechanisms also affects the reliability of the virtual environment. For example, if the attack is organized on the monitor of virtual machines, the attacker may unnoticed by the security system, which are in the virtual machines can edit, copy or block the flow of information. Thus, if a hacker gains access to control capabilities, he will not only be able to edit data, but also steal it throughout the virtual network. Therefore, to avoid this situation, you need to protect the administration or servers of virtual machines. In addition, you need to create specialized information security tools that can monitor traffic inside the required server. At the same time, compliance with basic fire safety rules is also important for the safe operation of servers.

У даній статі запропонований спосіб, який дозволяє ефективно компілювати замикання вкладених функцій з захопленими змінними у проміжну мову CIL платформи .NET. Розглянутий спосіб базується на ідеї зміни проміжного представлення програми шляхом створення класу, який зберігає значення замкнених змінних, і передається останнім аргументом у вкладену функцію. Це дозволяє зв’язати виклик функції з її захопленими змінними. Генерація CIL інструкцій відбувається вже для перетвореної програми. Результатом роботи способу є згенерований код, який демонструє кращу швидкодію, ніж код, що генерується існуючим аналогом.

Дослідження тестового покриття на рівні байт-коду Java
Authors: Kolomoiets H.
Published: July 2022

Кількісною характеристикою оцінки обсягу тестування програмних продуктів, рішення про завершення тестування і, врешті, визначення якості продукту та готовності його до дистрибуції є ступінь тестового покриття. Покриття коду тестами є підтипом тестового покриття і воно найчастіше визначається інженерами-програмістами. Ми можемо вимірювати ступінь покриття коду тестами за декількома критеріями, такими як покриття методу, покриття рядків, покриття операторів, покриття гілок, покриття умов гілок тощо. При оцінці результатів вимірювання покриття популярними інструментами, наприклад JaCoCo Java Code Coverage Library, за критеріями операторів, гілок та умов гілок результати є неочевидними внаслідок того, що у таких випадках ступені покриття визначаються на рівні байт-коду. Стаття наводить детальний аналіз визначення ступенів покриття на рівні байт-коду за вказаними критеріями при модульному тестуванні типових методів з комбінованою умовою з логічним оператором AND (&) у першому випадку та з оператором швидкої оцінки AND (&&) у другому випадку. Отриманий байт-код методів вивчався з відтворенням станів стеку операндів до та після кожної команди, що дозволило правильно інтерпретувати переходи у програмі. Було з’ясовано, що при визначенні ступеню покриття за критеріями гілок та умовами гілок враховувались виключно інструкції умовних переходів, причому кількість гілок дорівнювалася подвоєній кількості таких інструкцій. Також були визначені ступені покриття коду тестами за критеріями операторів та гілок для обох методів при різних наборах вхідних даних. Було визначено, що внаслідок визначення ступенів покриття саме на рівні байт-коду, для 100% покриття методу з комбінованою умовою з логічним оператором AND (&) достатньо два тестових прогони, у той час як для того ж методу, але з комбінованою умовою з оператором швидкої оцінки AND (&&) необхідні, як мінімум, три прогони.

Обґрунтовано актуальність застосування нейромереж для дослідження адаптивних траєкторій навчання на основі аналізу поточних характеристик засвоєння інформаційних квантів студентом, що забезпечує успішне проведення дистанційного навчання з використанням відкритих комунікаційних платформ. Представлено адаптивний процес засвоєння студентом нових знань архітектурою багатошарового персептрона, в якій кожен нейрон розглядається як певний урок, а навчальний процес представлено як рух студента по окремих уроках. Реалізовано застосування для навчання мережі алгоритму зворотного поширення помилки та методу найменших квадратів. Це дало можливість шляхом паралельного й одночасного уточнення параметрів мережі ітераційно коректувати вагові коефіцієнти синаптичних зв’язків кожного з нейронів на основі мінімізації середньоквадратичного відхилення між правильною та реальною відповіддю мережі. Побудовано загальний алгоритм адаптивного навчання з використанням нейромережі та описано етапи його функціонування. Визначено перспективи подальших досліджень, направлених на застосування модифікацій алгоритму зворотного поширення помилки та вдосконалення підбору правил корекції вагових коефіцієнтів.

Принципи формування архітектури мереж стільникового зв’язку п’ятого покоління
Authors: Mykytenko S.
Published: July 2022

Проведено огляд принципів формування архітектури стандарту стільникового зв’язку п’ятого покоління (5G). Розкрито основні обмеження та принципи реалізації архітектури 5G. Визначено основні стеки протоколів 5G NR, які поділено на три основні рівні: фізичний; MAC, RLC, PDCP; RRC, які представлено схематично. Описано сутність мережі O-RAN, яка пропонує можливість повного (або часткового) виконання стека протоколів у віддаленому обчислювальному центрі, реалізованому на персональному комп'ютері, за рахунок чого реалізується концепція хмарної C-RAN (Cloud RAN). Проілюстровано поточну архітектуру 3GPP 5G з відокремленням недоліків наведеної архітектури. До основних напрямків, які потребують детального опрацювання віднесено, у першу чергу, розділ протоколів між радіоінтерфейсом і стеком протоколів N2/N3 вузлів RAN, що дозволить реалізувати стійкий доступ та постійний зв’язок у мережі, мінімізуючи зовнішні впливи, по-друге, модифікація панелі управління обладнання користувача, за рахунок керування потоком даних висхідної лінії, що дозволить панелі управління гнучко підключатися до різних мереж, таких як 5GC, 4G CN, або безпосередньо до Інтернету. Наведено новітню архітектуру стандарту стільникового зв’язку п’ятого покоління (5G), яка зв'язується з 5G через уніфікований об'єкт взаємодії замість окремих функцій взаємодії. Запропоновано модифікацію панелі управління обладнання користувача, наголошено на мінімальних програмних змінах в архітектурі 3GPP 5G, які легко реалізувати, а найголовнішим у запропоновано підході є відсутність змін у протоколі між панеллю управління користувача та gNB та 5GC, а також gNB та 5GC. Підкреслено, що архітектура стандарту стільникового зв’язку п’ятого покоління RAN 5G володіє спрощеною інтеграцією з кількома RAT, ефективне керування потоками даних у RAN, гнучкість підключення до будь-якої CN або Інтернету безпосередньо через RAN на основі 4G/5G/Wi-Fi.

On a Conjecture Concerning Shuffle-Compatible Permutation Statistics
Authors: Yang Lihong , Yan Sherry H.F.
Published: July 2022

The notion of shuffle-compatible permutation statistics was implicit in Stanley's work on P-partitions and was first explicitly studied by Gessel and Zhuang. The aim of this paper is to prove that the triple ${\rm (udr, pk, des)}$ is shuffle-compatible as conjectured by Gessel and Zhuang, where ${\rm udr}$ denotes the number of up-down runs, ${\rm pk}$ denotes the peak number, and ${\rm des}$ denotes the descent number. This is accomplished by establishing an ${\rm (udr, pk, des)}$-preserving bijection in the spirit of Baker-Jarvis and Sagan's bijective proofs of the shuffle compatibility property of permutation statistics.

Authors: Sophian Alfi
Published: July 2022

Escherichia coli bacteria test on contaminated meat processed food products with several variations of positive control concentrations was carried out to provide additional information about determining the LOD value in the test method for the detection of Escherichia coli pathogenic bacteria. The purpose of this study was to detect and identify bacterial contamination of Escherichia coli ATCC 25922 in contaminated meat processed food products with variations in the concentration of positive control. The method used to identify is the enrichment method, using enrichment media to grow the suspected target bacterium Escherichia coli ATCC 25922 spiked in meat-processed food products, followed by isolation using selective media and ending with confirmation and affirmation tests. The samples used were 10 packages of processed meat food products. The samples were then spiked using various concentrations of positive control Escherichia coli 5, 10, 50, and 100 colonies/gr. The data from the research showed that all samples from the treatment of variations in the concentration of spike positive controls were detected and identified the presence of Escherichia coli ATCC 25922. Based on the results of this study, it can be concluded that all samples spiked with various variations in the concentration of positive control were detected and identified Escherichia coli ATCC 25922.
Experimental Study Regarding the Mechanical Behavior of PPR Pipes
Authors: Ramadan Ibrahim , Tanase Maria
Published: July 2022

The PPR pipes are more and more used in different industrial applications, due to their multiple advantages compared with the conventional metallic pipes. The experimental study presented in this article, was conducted in two directions, analyzing the behavior of welded PPR pipes and also the behaviour of unwelded PPR pipes exposed to different aggressive environments. In the second investigation, the PPR pipes were immersed in different chemically active environments as gasoline, sodium hypochlorite (NaClO), water + sodium hypochlorite (NaClO)-20% NaClO volume concentration, for a period of 3 weeks (21 days), in order to reveal the influence on the mechanical properties of the PPR pipes. The examination was made by using both visual inspection and tensile and bending tests. The investigations made have led to the conclusion that the presence of sodium hypochlorite do not affect the mechanical properties of PPR pipes, unlike the gasoline which significantly decrease the yield stress value. For the welded PPR pipes it was found that they failed at pressures of about 180 bar. Although the optimal welding parameters, recommended by the manufacturer, were modified (maintenance time), the only sample that failed in the welded joint was the one with the most acute misalignment and the shortest welding time. However, the sample withstood high pressures, reaching about 55% of the burst pressures obtained for welded pipes with the recommended welding parameters. The need to conduct such studies derived from the fact that most of the information regarding the behavior of PPR pipes is provided by the manufacturers and there is insufficient information in the scientific literature.

Published: July 2022

Novel block biocopolymers were made by copolymerizing the prepared polylactide-dipenta-erythritol macromonomer with two different monomers, N-hydroxyethyl acrylamide (HEAA) and N,N-dimethylamino ethyl methacrylate (DMAEMA), with an activator generated by atom transfer radical polymerization (ATRP), to have a different duplicating unit of 10, 25, 50, and 100. ATRP employs a copper(I) bromide (CuBr) catalyst system with N, N, N′, N′′, N′′-pentamethyl diethylenetriamine (PMDETA). Different spectroscopic and analytical methods used for characterization of the prepared biocopolymers, such as FT-IR, 1H NMR, 13C NMR, and GPC, showed that they had narrow dispersity with controllable molecular weight and were accompanied by nanostructures as examined by SEM technique on all biocopolymers, confirming the correctness of the expected structures of biocopolymers. The shape and size of the produced polymeric nanoparticles were determined using a scanning electron microscope (SEM), and they were developed using the Image-J application.

Authors: Zhang Hongshen , Zhao Yingjie , Zheng Hongfei
Published: July 2022

The recycling and high-valued added reuse of automotive plastics have elicited global attention as the number of end-of-life vehicles increase. In the paper, the two-stage high-voltage electrostatic separation is used to explore the sorting of passenger vehicle plastic mixtures of PP, ABS and PVC. The purities of PP, ABS and PVC are all higher than 97%, and the recovery rates are 55%, 93%, and 48%, respectively. Taking PP plastic as an example, the mechanical properties of the recycled materials and the different ratios of recycled and new material mixtures are studied. Results show that the passenger car bumpers reproduced with a 7:3 ratio of new and recycled materials can satisfy the performance requirements. The finding provides a reference for the high additional value reuse of other automotive plastics.

Atherosclerosis can affect the blood vessels in any region of the body and the stenosis (narrowing) can be located on an artery that vascularize important organs, such as the brain, abdominal organs or limbs. The endovascular surgery is a modern approach to vascular pathology through minimally invasive techniques (puncture, minimally vascular approach) and it represents an enrichment of the arsenal of surgical techniques and brings considerable improvements in post-operative and long-term outcomes The use of polymer drug-coating balloons is an attractive alternative because they can offer the promise of an improved patency compared to the simple balloons and a reduction in the need for stents. The aims of this study were to describe the polymer materials and to compare the medical endpoints obtained in angiosome-targeted infrapopliteal angioplasty using a simple balloon with two layers, based on polyethylene, and respectively a drug-coated balloon that contains a multiblock copolymer from polyethylene, poly(cylohexylethylene), polyisoprene and poly(1,3-butadiene) covered by Paclitaxel. The balloons were characterized by differential scanning calorimetry, stress-strain and puncture tests in order to describe their physical and mechanical characteristics. On the other hand, 51 patients with critical limb ischemia were treated with different balloon angioplasty and they were monitored for 12 months after the intervention; the following parameters have been evaluated: diabetes, hypertension, renal insufficiency, hemodialysis, stroke, dyslipidemia, heart disease, heart failure, body mass index, number of angiosomes, creatinine, and wound healing, leg salvage and amputation-free survival at 1, 2, 3, 6, 9, 12 months. Significant associations were found in the case of anterior-tibial-artery and posterior-tibial-artery angioplasy and the age, hypertension and renal insufficiency. On the other hand, the results indicate that the drug deposition on the surface of the balloons lead to improved values for the observed medical endpoints. In conclusion, this study reveals that angiosome-based infrapopliteal angioplasty with drug-coated balloons can be associated with better wound healing and leg salvage.
