Reflexões sobre a formação continuada de professores na contemporaneidade
Authors: Lidoino Andreia Cristina Pontarolo , Santos Digilaini Machado dos , Reis Geilson de Arruda
Published: August 2020

Mesmo vivendo a contemporaneidade, através das ressignificações de sociedade, de cultura, de ensino e aprendizagem, as práticas pedagógicas continuam obsoletas a essas transformações. Nesse sentido, a escola e os profissionais de educação são convidados a rever seu papel social e pedagógico para melhor atender as necessidades dos alunos e as demandas da escola.  Este artigo de cunho qualitativo tem como objetivo refletir sobre o papel do professor em relação aos processos de ensino e aprendizagem na contemporaneidade, perpassando pelo viés da formação docente continuada. Por meio de pesquisa bibliográfica sustentada por teóricos que versam sobre o tema como: Freire, Prado & Cunha, Mercado, Moran, Nóvoa, Nunes, Schimitt e Shõn entendemos que não é viável permanecer com as mesmas práticas em um espaço e tempo que se modificaram com a globalização, que estão em movimento contínuo de remodelação. Compreendemos que os processos de ensino e aprendizagem precisam estar alicerçados na docência reflexiva, permitindo professores e alunos construir coletivamente e colaborativamente ações e reflexões que os levem a busca do conhecimento, colocando-os como eternos aprendizes.

A atual dinâmica que permeia o mercado- competitivo e globalizado- exige que as organizações direcionem o foco para o relacionamento com os clientes, transcendendo a oferta de produtos e/ou serviços, e sim reconhecendo o que o cliente deseja. Neste sentido, novos modelos de negócios foram incorporados, com destaque para o sistema cooperativista agroindustrial, alinhado especialmente a vocação agrícola brasileira. Assim, a presente pesquisa tem como objetivo realizar um levantamento das estratégias de marketing adotadas pela Cooperativa COMIGO – Unidade de Iporá – Goiás, considerando ser a maior fornecedora de insumos agropecuários no município. Os procedimentos metodológicos utilizados foram, revisão bibliográfica de temas correlatos ao marketing, composto de marketing e cooperativa agroindustrial, assim como a realização de entrevista semiestruturada com o gerente da unidade objeto deste estudo. Os resultados demonstram que as ações adotadas são definidas na sede administrativa pela assessoria de comunicação e contemplam todas as unidades de negócio. Paralelamente, são percebidas ações que atendam aos interesses da comunidade local, como patrocínios, apoio a ações sociais, parcerias com instituições de ensino e associações entre outros.

Nos últimos anos, a relevância dos processos de esterilização e antissepsia tem sido bastante discutida entre os profissionais da área de saúde, incluindo cirurgiões-dentistas. No entanto, na prática odontológica, a qualidade da água utilizada nos equipamentos, aparentemente inofensiva, pode ser considerada um fator de risco para a saúde do paciente. Diante disso, o objetivo deste estudo foi verificar a presença de contaminação em equipamentos odontológicos e avaliar a qualidade da água dos reservatórios desses equipamentos, por meio de análise microbiológica. Foram coletadas 12 amostras de água diretamente dos reservatórios das cadeiras odontológicas e 12 amostras da seringa tríplice de seis clínicas multidisciplinares do Departamento de Odontologia da Universidade Federal do Rio Grande do Norte (UFRN). O plaqueamento foi realizado com base no método Spread Plate, em meio ágar BHI (Brain Heart Infusion) com incubação subsequente em estufa bacteriológica programada de 37,5°C a 38°C, por um período de 24 a 48 horas. Os resultados demonstraram que 83% das placas incubadas apresentaram crescimento expressivo de fungos filamentosos e bactérias que, devido ao odor de tutti-frutti e com base nas características macroscópicas, sugere-se que sejam do gênero Pseudomonas. Nesse contexto, os achados deste estudo atestam a urgência da elaboração de uma rotina de cuidados sanitários, viabilizando a descontaminação dos sistemas de água dos equipamentos bem como de seus reservatórios, atendendo aos requisitos de segurança do paciente, que deve ser inerente aos consultórios odontológicos.

Objetivo: Relatar o uso de gerontotecnologias com um grupo de idosos em uma Unidade Básica de Saúde (UBS) localizada em Belém-PA. Metodologia: Trata-se de um trabalho descritivo, com abordagem qualitativa do tipo de relato de experiência,  realizado no mês maio de 2019, pelos membros da Liga Acadêmica de enfermagem em Saúde do Idoso (LAESI). As estratégias utilizadas envolveram gerontotecnologias de forma lúdica, incluindo “jogos da atenção”, “dance na cor”, “jogo da memória”, “quebra cabeças”, “jogo da vareta” e “somando e brincando”. Resultados e discussão: Durante o uso dessas tecnologias percebeu-se que houve aceitação da metodologia proposta evidenciada pela participação ativa das idosas. A aplicabilidade das gerontotecnologias direcionada a pessoa idosa ajuda na manutenção da qualidade de vida no período da senescência, permitindo identificar possíveis fatores de riscos que compreendem o declínio da cognição, memória, percepção visual e mobilidade. Isso possibilita o estabelecimento de intervenções para evitar complicações irreversíveis na vida da pessoa idosa. Considerações finais: Observou-se que os benefícios observados poderiam ser melhores se houvesse constância de atividades destinadas aos idosos com uso de gerontotecnologias na atenção básica trabalhando crucialmente na promoção e saúde.

Trends and possible causes of cloudiness variability in Montenegro in the period 1961-2017
Authors: Burić D , Stanojević G
Published: August 2020

Cloudiness is an important climate parameter, and it is closely related to insolation, temperature, and precipitation. Total cloud cover (TCC) data along with the number of cloudless (CL) and overcast (OC) days from 18 stations in Montenegro during the period 1961-2017 were used to determine the seasonal trends and possible causes of cloudiness variability. The Mann-Kendall test and Sen’s slope were used for trend detection. We found statistically significant (p < 0.05 and p < 0.10) decreasing (increasing) trends in TCC (the number of CL days) in winter, spring and summer. The exception was in autumn, when an increase (decrease) in the TCC (CL days) was shown, but in most cases, these changes were insignificant. The number of OC days declined in coastal and central regions, while a positive trend was found in the northern region for all seasons. The increase in the number of CL days during the summer and winter was more pronounced compared to the decreasing trend in the number of OC days. Pearson’s correlation (r) was used to access the relationship between cloudiness and principal modes of atmospheric variability such as North Atlantic Oscillation (NAO), Summer North Atlantic Oscillation (SNAO), Arctic Oscillation (AO), East Atlantic Oscillation (EA), East Atlantic-West Russian Oscillation (EAWR), Scandinavian Pattern (SCAND), Polar-Eurasian Oscillation (POLEUR), North Sea-Caspian Pattern (NCP), and South Oscillation (SOI) as well as regional patterns of climate variability—the Mediterranean Oscillation (MOI) and Western Mediterranean Oscillation (WeMO). A significant consistency (r > 0.60, p < 0.05) was found between time series of certain atmospheric circulation patterns and cloud parameters (NAO, AO, EAWR, SCAND, NCP, and MOI-1), especially in the colder half of the year.
New Scots? Eastern European young people's feelings of belonging and national identity in Scotland post-Brexit
Authors: Sime Daniela
Published: August 2020

This article examines the impact of Brexit on young people aged 12–18 who had moved to Scotland from Central and Eastern Europe. It draws on empirical data collected with over 250 young people who contributed to an online survey and focus groups between 2016–2018, immediately after the Brexit Referendum took place. The paper examines young people's feelings of national identity and how their sense of belonging has been impacted by Brexit. The key findings reveal that factors such as their everyday experiences of racism and xenophobia and perceptions of what other people, often their friends, might think about who gets to belong were identified as significant to the identities young migrants felt able to claim. While many young people expressed a strong sense of belonging in the UK as a whole and over half said they were feeling Scottish, access to a Scottish national identity seems to be restricted and often denied to them. At the same time, many felt able to occupy the national identity of their country of birth or claim hyphenated identities that included Scottishness and a European identity. In the context of Brexit, this poses a challenge for making New Scots feel like they belong in Scotland, as many may now decide to review their plans to remain in Scotland long-term if their rights change.
‘Brexit’ and the Scots in England: A diaspora facing uncertainty?
Authors: Leith Murray Stewart , Sim Duncan
Published: August 2020

Brexit has brought many uncertainties, including the future position of UK-based EU migrants. Our concern is with a much less studied group, albeit one of the largest socio-political sub-groups within England – the Scots. These are migrants who live in a different country but within the same state and recent constitutional decision making has not been kind to them. In 2014, English based Scots had no vote in the independence referendum and in the EU referendum they witnessed Scotland voting significantly differently to England, resulting in ongoing tensions between the UK and Scottish Governments. If Brexit leads to another independence referendum, what are the implications for Scots in England, in terms of their citizenship, identity, and residence in a very different (r)UK? We explore their status in a (r)UK outside the EU, we speculate on whether some might move back or whether, if they remain, they would experience hostility within post-Brexit England. Might the current position of the English Scots tell us something about the future relationship between England and Scotland?
Stay or Go? – Roma, Brexit and European Freedom of Movement
Authors: Clark Colin
Published: August 2020

The spectre of Brexit has raised issues of concern for Roma communities living and working in Scotland and other parts of the UK. The effective ending of freedom of movement has produced new uncertainties and insecurities for people living outside their EU countries of origin, especially for those who are racialised and stigmatised by ‘hostile environment’ policies. Brexit is best understood as both a process and effect of everyday bordering as well as a continuation of historically embedded structural divisions. This paper looks at everyday Roma life in Glasgow, via the work of the NGO Romano Lav (Roma Voice), to assess how Brexit is impacting on people's lives. Further, the paper examines how Scotland can best move forward in terms of independence and the European project. It is argued that a second independence referendum that gives full political independence to Scotland is the only way to secure future EU membership and freedom of movement.
Scotland and Brexit: identity, belonging and citizenship in uncertain times
Authors: McCollum David
Published: August 2020

This article offers some reflections on the lessons readers might take from the papers in this special issue. These are framed through consideration of three key themes: Scottishness, nationhood and national identity; the search for belonging, not least in relation to migrants’ emotional responses to Brexit; and the practical questions that Brexit poses for citizenship(s) and ‘settled’ status. In considering these themes, attention is drawn towards three areas which are ripe for further study. Several of the articles bring into focus the notion of Scottish exceptionalism, provoking questions about what impacts this exceptionalism, or perhaps more importantly perceptions of it, may have at policy and attitudinal levels. Questions too, are posed about the heterogeneity of perception, experience and response to Brexit amongst ECE migrants in Scotland. Finally, it can be seen that Brexit has been a protracted process and a source of anxiety and anguish, not least for those who have made Scotland their home. Looking forward, there will be more Brexit related tension to come, a prospect hugely complicated by the impacts of Covid-19.

Published: August 2020

In this article, we examine how the law affects the social solidarity. Our fundamental principle is that solidarity protects society from the lawlessness, the injustice, the isolation, the vulnerability and after all from the disintegration. In our article, we tried describing the reasons, why people act on basis of solidarity, which could be the root of their behavior and how solidarity works in practice. The COVID-19 situation, in view of the pandemic, create some interesting, crucial in terms of societal and economic well-analyzable opportunities of solidarity. We summarized the philosophical origins, the moral framework and the fundament of this term. We sketched the Durkheimian sociology, which is arguing that the cohesion of the modern, “organic” society is built up by the interdependency-system of more and more differentiated and specialized individuals. Before covering the global society in practice, we collected the sociological aspects as well, all the way to evictions.
Maintenance (r) Alpha Lipoic Acid Reduces Sudden Cardiac Death in Geriatric Diabetes Mellitus II Patients
Authors: L Murray Gary , Colombo Joseph
Published: August 2020

Background: Diabetes carries a two-fold risk of Sudden Cardiac Death (SCD). Diabetic Autonomic Neuropathy (DAN), often progressing to Cardiovascular Autonomic Neuropathy (CAN, critically low parasympathetic tone [P]), increases death 3.5-fold over 5 years, half sudden or non-renal. Oxidative stress is a major cause of DAN. Also, increased sympathetic tone (S), High Sympathovagal Balance [SB>2.5] increases SCD risk. Objective: Dysautonomic diabetic II patients were treated with the antioxidant (r) Alpha Lipoic Acid (ALA), autonomic function followed, and Sudden Death (SD) compared to untreated patients. Methods: 133 patients (mean age 66y/o) with DAN or CAN, diagnosed using the ANX 3.0 Autonomic Monitor (Physio PS, Inc., Atlanta, GA) was offered (r)-ALA: 83 agreed (Group 1), and 50 refused (Group 2). P and S were re-measured up to 3 times/yr (mean f/u 6.31 yrs); SCDs were recorded. Results: A 43% Relative Risk Reduction (RRR) in SCD occurred with (r)-ALA (25% SCD Group 1 vs. 44% SCD Group 2, p=0.0076). Initial to final patients with high SB or CAN were 21.7%-12% (p=0.010), 10.8%-15.7% (p=0.045), Group 1 vs. 24%-22% (p=ns), 6%-12% (p=0.083), Group 2. Only Group 1 survivors increased mean resting P. The progressive increase in P’s decline, increasing CAN risk, in the other patients correlated with mortality (p<0.001) and (r) ALA dose. Initially, Group 1 had insignificantly less high SB (p=0.449) and significantly more CAN (p=0.013) vs. Group 2. Finally, Group 1 had significantly less high SB (p=0.0967) vs. Group 2, also improving to insignificantly more CAN (p=0.261). Conclusion: (r)-ALA was associated with a 43% RRR of SCD and favorable P and S changes.
A Control Strategy of Actively Actuated Eccentric Mass System for Imbalance Rotor Vibration
Authors: Jung DaeYi
Published: August 2020

This paper explores the new control strategy of an actively actuated eccentric mass system (AAEMS) for cancelling the rotor imbalance vibration. The AAEMS consists of an eccentric mass with an actuator that actively moves around the circular guided track attached to the rotating rotor thus can generate an effective centrifugal force perpendicular to any tangential direction of the guided circular trajectory. Therefore, once the magnitude and angular position of the inherited static imbalance of the rotor are identified, this actively controlled system can be dispatched to the target angular position(s) where the effective centrifugal force due to rotor imbalance is completely or partially removed. This novel device is currently available and widely used in the vibration isolation problem. However, the study of its control strategy is quite limited, thus, herein, we proposed a new possible control technique, guaranteeing both the robust vibration isolation performance and less control power consumption. To meet such needs, three primary functions of AAEMS are addressed here. First, two (Extended) Kalman filters were employed to sequentially estimate the unknown imbalance of the rotor and the unknown coulomb friction induced between the contact surface of the circular track and the counter-contacted parts of AAEMS. Second, the position control of the AAEMS is achieved by a linear quadratic regulator (LQR)-based optimal control law, simultaneously minimizing the imbalance vibration of the rotor as well as the power consumption of its own actuator. Third, for the situation where the estimation and control errors are presented, thus causing the failure to an acceptable threshold for imbalance vibration, the trial-error-based fine-tuning angular position control was proposed. The effectiveness of the proposed control strategy was evaluated via the simulations and this study shows the practical potential for addressing the AAEMS-based imbalance vibration elimination.
Cluster Typology of Business Models of Start-Ups. (Example of Slovakia)
Authors: Slávik Štefan , Bednár Richard , Mišúnová Hudáková Ivana , Moravčíková Katarína
Published: August 2020

Start-up is an emerging micro-enterprise that has different characteristics to a larger and mature enterprise. Its viability depends mainly on a functioning business model. The purpose of the research study is to identify the basic types of business model regardless of the specific industry, and thus to penetrate deeper into the more general cognition of start-up business making. The research sample contains 106 start-ups, the business models of which are described using fourteen criteria, which are derived from the visualization of canvas. The research sample is divided by cluster analysis (Ward’s hierarchical agglomeration method) into nine clusters, hence types of business models. For a better understanding, the clusters were aggregated into four groups with similar business models. Grouping A is characterized by the model with a small range of processes, mostly with higher product differentiation, scarce resources and satisfying the common basic and higher needs. Grouping B is characterized by the model with a large range of processes and higher product differentiation and satisfying the common basic and higher needs or newer practical needs. Start-ups in grouping C have the model with considerable differentiation aimed at satisfying the common needs. Grouping D has the model based on cultivating relationships with customers, cheap satisfying of needs and use of ordinary resources. The models differ the most in the span of operational processes, segmentation and distribution, and differ the least in the relationships between customers, the cost–price ratio and protection against imitation. The practical use of the identified clusters lies in the fact that they are a reflection of the real behaviour of start-ups, they determine the real parameters of business models, and therefore they provide the founders of start-ups with verified patterns, the outlines of which are probably not definitive.
Redefining the Use of Sustainable Development Goals at the Organisation and Project Levels—A Survey of Engineers
Authors: Mansell Paul , Philbin Simon , Konstantinou Efrosyni
Published: August 2020

The United Nations’ (UN) Sustainable Development Goals (SDGs) aim to deliver an improved future for people, planet and profit. However, they have not gained the required traction at the business and project levels. This article explores how engineers rate and use the SDGs at the organisational and project levels. It adopts the Realist Evaluation’s Context–Mechanism–Outcomes model to critically evaluate practitioners’ views on using SDGs to measure business and project success. The study addresses the thematic areas of sustainability and business models through the theoretical lens of Creating Shared Value and the Triple Bottom Line. A survey of 325 engineers indicated four primary shortfalls for measuring SDGs on infrastructure projects, namely (1) leadership, (2) tools and methods, (3) engineers’ business skills in measuring SDG impact and (4) how project success is too narrowly defined as outputs (such as time, cost and scope) and not outcomes (longer-term local impacts and stakeholder value). The research study is of value to researchers developing business models that address the SDGs and also practitioners in the construction industry who seek to link their investment decisions to the broader outcomes of people, planet and profit through the UN SDGs.
Soybean Yield Estimation and Its Components: A Linear Regression Approach
Authors: Wei Marcelo Chan Fu , Molin José Paulo
Published: August 2020

Soybean yield estimation is either based on yield monitors or agro-meteorological and satellite imagery data, but they present several limiting factors regarding on-farm decision level. Aware that machine learning approaches have been largely applied to estimate soybean yield and the availability of data regarding soybean yield and its components (number of grains (NG) and thousand grains weight (TGW)), there is an opportunity to study their relationships. The objective was to explore the relationships between soybean yield and its components, generate equations to estimate yield and evaluate its prediction accuracy. The training dataset was composed of soybean yield and its components’ data from 2010 to 2019. Linear regression models based on NG, TGW and yield were fitted on the training dataset and applied to a validation dataset composed of 58 on-field collected samples. It was found that globally TGW and NG presented weak (r = 0.50) and strong (r = 0.92) linear relationships with yield, respectively. In addition to that, applying the fitted models to the validation dataset, model based on NG presented the highest accuracy, coefficient of determination (R2) of 0.70, mean absolute error (MAE) of 639.99 kg ha−1 and root mean squared error (RMSE) of 726.67 kg ha−1.
Molecular Assisted Selection for Pollination-Constant and Non-Astringent Type without Male Flowers in Spanish Germplasm for Persimmon Breeding
Authors: Blasco Manuel , Gil-Muñoz Francisco , Naval María del Mar , Badenes María Luisa
Published: August 2020

Persimmon (Diospyros kaki Thunb) species is a hexaploid genotype that has a morphologically polygamous gyonodioecious sexual system. D. kaki bears unisexual flowers. The presence of male flowers resulted in the presence of seeds in the varieties. The fruits of persimmon are classified according to their astringency and the pollination events that produced seeds and modify the levels of astringency in the fruit. The presence of seeds in astringent varieties as pollination variant astringent (PVA), pollination variant non-astringent (PVNA) and pollination constant astringent (PCA) resulted in fruits not marketable. Molecular markers that allow selection of the varieties according to the type of flowers at the plantlet stage would allow selection of seedless varieties. In this study, a marker developed in D. lotus by bulk segregant analysis (BSA) and amplified fragment length polymorphism (AFLP) markers, named DlSx-AF4, has been validated in a germplasm collection of persimmon, results obtained agree with the phenotype data. A second important trait in persimmon is the presence of astringency in ripened fruits. Fruits non-astringent at the ripen stage named pollination constant non-astringent (PCNA) are the objective of many breeding programs as they do not need removal of the astringency by a postharvest treatment. Astringency in the hexaploid persimmon is a dominant trait. The presence of at least one astringent allele confers astringency to the fruit. In this paper we checked the marker developed linked to the AST gene. Our goal has been to validate both markers in germplasm from different origins and to test the usefulness in a breeding program.
Effect of Nitrification Inhibitors on N2O Emissions after Cattle Slurry Application
Authors: Herr Christina , Mannheim Thomas , Müller Torsten , Ruser Reiner
Published: August 2020

Cattle slurry injection (INJ) has shown to be an efficient measure to reduce ammonia (NH3) losses from soils but it might also significantly increase nitrous oxide (N2O) emissions, which can dominate the total greenhouse gas (GHG) release in silage maize production (Zea mays L.). Nitrification inhibitors (NIs) are known for their potential to mitigate N2O. Therefore, we tested the effect of NIs added to cattle slurry before INJ on N2O fluxes from a Haplic Luvisol under silage maize in southwest Germany. We determined N2O fluxes at least weekly, with the closed chamber method over two full years. NIs differ in their chemical and physical behavior and we therefore tested a range of commercially available NIs: 3,4-dimethylpyrazole phosphate, 3,4-dimethylpyrazol succinic acid, a mixture of both, nitrapyrin, dicyandiamide, and 1,2,4 triazol and 3-methylpyrazol. Although not significant, INJ treatments with NI showed lower mean annual N2O emissions than the INJ treatment without NI in the 1st year. The emission reduction by NI of 46% in the 2nd year was statistically significant. In both years, we did not find any difference in N2O release, crop yield, or nitrogen removal between the different NI treatments. In the 1st year, which was extraordinary dry and warm, emission factors (EFs) for all INJ treatments were 4 to 8-fold higher than default EF from the IPCC. Even in the 2nd year, only three NI treatments reached EFs within the range provided by the IPCC. Direct N2O accounted for between 81 and 91% of the total GHG emission. Area- and yield-related GHG emission of the broadcast application with subsequent incorporation was in both years in the statistical class with lowest emission. In contrast, INJ with NIs showed similar GHG emissions in only one year, and consequently, incorporation was found to be the optimum management practice for livestock farmers in our study region.

Economic development, international food and feed demand, and government policies have converted Brazil’s natural ecosystems into agricultural land. The Integrated Farm System Model (IFSM) was evaluated using production, economic, and weather data collected on two cooperating farms in the Legal Amazon and Cerrado biomes in the Midwest state of Mato Grosso, Brazil. Three sustainable agricultural intensification strategies, namely grain supplementation, pasture re-seeding, and pasture fertilization were simulated in IFSM with double the beef cattle stocking density compared to extensive grazing. Livestock dry matter consumption simulated in IFSM was similar for pasture grazing estimates and actual feed consumed by beef cattle on the two collaborating farms. Grain supplementation best balanced beef production and profitability with lower carbon footprint compared to extensive grazing, followed by pasture fertilization and pasture re-seeding. However, pasture re-seeding and fertilization had greater use of water and energy and more nitrogen losses. Human edible livestock feed use was greatest for grain supplementation compared to other modeled systems. While grain supplementation appears more favorable economically and environmentally, greater use of human edible livestock feed may compete with future human food needs. Pasture intensification had greater human edible feed conversion efficiency, but its greater natural resource use may be challenging.

The main goal in the treatment of large bone defects is to guarantee a rapid loading of the affected limb. In this paper, the authors proposed a new reconstructive technique that proved to be suitable to reach this purpose through the use of a custom-made biomimetic porous titanium scaffold. An in vivo study was undertaken where a complete critical defect was experimentally created in the diaphysis of the right tibia of twelve sheep and replaced with a five-centimeter porous scaffold of electron beam melting (EBM)-sintered titanium alloy (EBM group n = 6) or a porous hydroxyapatite scaffold (CONTROL group, n = 6). After surgery, the sheep were allowed to move freely in the barns. The outcome was monitored for up to 12 months by periodical X-ray and clinical examination. All animals in the CONTROL group were euthanized for humane reasons within the first month after surgery due to the onset of plate bending due to mechanical overload. Nine months after surgery, X-ray imaging showed the complete integration of the titanium implant in the tibia diaphysis and remodeling of the periosteal callus, with a well-defined cortical bone. At 12 months, sheep were euthanized, and the tibia were harvested and subjected to histological analysis. This showed bone tissue formations with bone trabeculae bridging titanium trabeculae, evidencing an optimal tissue-metal interaction. Our results show that EBM-sintered titanium devices, if used to repair critical bone defects in a large animal model, can guarantee immediate body weight-bearing, a rapid functional recovery, and a good osseointegration. The porous hydroxyapatite scaffolds proved to be not suitable in this model of large bone defect due to their known poor mechanical properties.

The request for functional and healthy meat presents a challenge to modern animal nutritionists and rabbit meat consumption appears to increase alongside the aging population. Novel functional feeds for food-producing animals gather the interest of the scientific community and acorns appear frequently accounted among non-competitive-with-human feeding sources, above all in slow food production systems. This investigation aimed to assess the response to acorns combined in the diet of 40 fattening rabbits, in respect of growth performance, carcass characteristics and fatty acids composition in perirenal fat. A same commercial fattening diet combined or not with shredded acorns (control, CON = 0 vs. acorn combined diet, ACD = 200 g/kg feed as fed weight, respectively) was administered for six weeks to two groups of Separator rabbits, consisting of 20 animals each. No differences in feed conversion, carcass weight at slaughter and carcass yields (24 h) were found between groups at the end of the experimental feeding. Perirenal fat profile of rabbits from the ACD group pointed to significant differences in ΣPUFA content (25.1 vs. 31.6, as a percentage of total lipids, respectively, p < 0.001) and in the Σ n − 6/n − 3 ratio (5.95 vs. 2.41). In conclusion, acorns can be used as an energy source in mixed feeds for rabbits, especially in slow production systems.

Authors: Bellucci Maria Cristina , Volonterio Alessandro
Published: August 2020

Aminoglycosides are a class of naturally occurring and semi synthetic antibiotics that have been used for a long time in fighting bacterial infections. Due to acquired antibiotic resistance and inherent toxicity, aminoglycosides have experienced a decrease in interest over time. However, in the last decade, we are seeing a renaissance of aminoglycosides thanks to a better understanding of their chemistry and mode of action, which had led to new trends of application. The purpose of this comprehensive review is to highlight one of these new fields of application: the use of aminoglycosides as building blocks for the development of liposomal and polymeric vectors for gene delivery. The design, synthetic strategies, ability to condensate the genetic material, the efficiency in transfection, and cytotoxicity as well as when available, the antibacterial activity of aminoglycoside-based cationic lipids and polymers are covered and critically analyzed.

The conventional electromagnetic ultrasonic transducers (EMATs) rely on the static magnetic field created by magnets. The magnet increases the size of the EMATs, and the strong magnetic force of the magnet attracts the detected steel and even ferromagnetic particles. It can cause mechanical damage to the transducer and the detected objects. A new high-energy acoustic excitation system, without a static bias magnetic is designed, which does not include any magnets. As the core of the system, the high-energy pulse excitation power supplies a transient high voltage to the excitation coil by the LC oscillation circuit. The maximum amplitude of current can reach 1700 A, which is much larger than the current in the conventional EMATs. Compared with the conventional EMATs, the intensity of the ultrasonic signal is greatly strengthened and the size of the EMAT is effectively reduced. Therefore, it can detect high-temperature steel plates at a higher lift-off distance. In this paper, the transduction mechanism of high-energy pulse electromagnetic acoustic on ferromagnetic materials was studied, and the high-energy pulse excitation coil used for the A0 mode Lamb wave was designed. The interaction rule of the magnetic field, the force field, and the acoustic field, was obtained. Then, the EMAT lift-off characteristic experiment of the high-energy pulse excitation was carried out, and the defect detection experiment was conducted on a cracked steel plate. The results show that the A0 mode Lamb waves have caused a high signal-to-noise ratio and can accurately locate the crack, which has a great advantage in detecting the microcrack defects of ferromagnetic materials.

Recently, various cold plasma sources have been tested for their bactericidal and fungicidal effects with respect to their application in medicine and agriculture. The purpose of this work is to study the effects of a 2.45 GHz microwave generated plasma torch on a model yeast example Candida glabrata. The microwave plasma was generated by a surfatron resonator, and pure argon at a constant flow rate of 5 Slm was used as a working gas. Thanks to a high number of active particles generated in low-temperature plasma, this type of plasma has become highly popular, especially thanks to its bactericidal effects. However, its antimycotic effects and mechanisms of fungal inactivation are still not fully understood. Therefore, this study focuses on the antifungal effects of the microwave discharge on Candida glabrata. The main focus is on the measurement and evaluation of changes in inactivation effects caused by varying initial concentration of Candida glabrata cells, applied microwave power and exposure time. The discharge was applied on freshly inoculated colonies of Candida glabrata spread on the agar plates and its inhibitory effects were observed in the form of inhibition zones formed after the subsequent cultivation.
