Published: October 2020

Aim: to evaluate the efficacy of non-pharmacological sedation method with concentrate glucose solution during the hearing test in infants of the first 3 months of life. Patients and Methods: a non-randomized clinical study on the efficacy of non-pharmacological sedation method with 25% glucose solution was performed during the hearing tests (tympanometry and otoacoustic emission) in infants from birth to 3 months of life versus breastfeeding in three parallel groups. The first group included infants examined with the proposed sedation method with 25% glucose solution. The second group consisted of patients who underwent the hearing test within an hour after feeding (n=30). The third group included infants examined an hour or more after feeding who didn’t underwent the sedation (n=24). To evaluate the efficacy of the proposed method, we used the Newborn Acute Pain (DAN) scale. Results: in the infant group receiving 25% glucose solution during the test, the DAN score was 1 (Q25; Q75 (0; 2)) point; in infants examined after feeding — 2 (2; 4) points, and in the third infant group — 4 (4; 5) points. The Kruskal-Wallis test showed statistically significant differences between patient groups (p<0.0001). Subsequent post hoc analysis established the significance of differences in infant behavior between groups where sedation with glucose was and wasn’t performed (p<0.0001), as well as between infants examined after feeding and after sedation with glucose (p<0.0001). Conclusions: the use of 25% glucose solution reduces the discomfort reaction in infants of the first 3 months of life when conducting the hearing test and is more effective than breastfeeding. The hearing test of infants in this age group should be performed within the first hour after feeding. KEYWORDS: hearing test, hearing loss, infants, glucose, non-pharmacological sedation, endogenous opiates. FOR CITATION: Merkulova E.P., Ustinovich K.N.

Introdução: Recentemente, houve crescimento da incidência do câncer de pele. Radiação solar, história familiar, imunossupressão, pele clara e idade constituem fatores de risco da doença. Objetivo: Correlacionar a mortalidade do câncer de pele com variáveis socioeconômicas. Método: Estudo ecológico, utilizando a planilha de dados da incidência de radiação solar do projeto aquecedor solar de baixo custo (ASBC), e indicadores de condições de vida do Censo de 2010. Os dados foram exportados para o SPSS 14.0, para analisar a correlação (coeficiente de correlação de Spearman), e as variáveis foram comparadas. Resultados: Associações estatisticamente significantes ocorreram entre o coeficiente de mortalidade por câncer maligno de pele com a renda familiar média (r=-0,316, p<0,006) indicando que, quanto maior a renda, menor a mortalidade por neoplasia maligna, ocorrendo o mesmo com a proporção de óbitos evitáveis em menores de 4 anos (r=-0,292, p<0,01) e a proporção de mortes evitáveis entre 5 e 74 anos (r=-0,372, p<0,001). A proporção da população ganhando menos de 1/2 salário-mínimo (r=0,232, p<0,05) indica que, quanto maior a proporção populacional com renda inferior a 1/2 salário-mínimo, maior será a mortalidade por neoplasia maligna, similar à proporção da população ganhando menos de 1/4 de salário-mínimo (r=0,229, p<0,05). Conclusão: Sendo um assunto de saúde pública intimamente relacionado à renda, o câncer de pele ainda carece de ações de prevenção primária e secundária.
The Mobility of Education Policy in the 21st Century: Lessons from Other Fields
Authors: Ruby Alan , Li Aisi
Published: October 2020

The ways information about national education policies is exchanged and interpreted is a field of comparative education that is under-developed. What discussion and analysis there is seems to ignore the insights and models prevalent in other domains. We looked to fields like political science, and economic and social development for concepts to strengthen the analysis of education policy mobility between nations. We found an abundance of metaphors most of which fail to capture key elements of policy diffusion including the notion that ideas change as they cross cultural boundaries. We observe that policy transfer can be purposefully initiated by the host as well as a product of coercion or external incentives. Our principal conclusions are that common framings of traveling education policies are linear, one-directional and marked by an air of beneficence. They overlook the importance of context and the actions of sovereign nations in policy formation.
Does Provision of Smart Services Depend on Cooperation Flexibility, Innovation Flexibility, Innovation Performance or Business Performance in SMEs?
Authors: Kanovska Lucie , Doubravsky Karel
Published: October 2020

Many manufacturers provide a lot of accompanying services to their products. However, not all of them supply smart services, because the move towards these is not easy, especially for SMEs, which often struggle with a lack of money, insufficient digital technologies or unskilled employees. The aim of this paper is to find out if smart service provision depends on cooperation flexibility, innovation flexibility, innovation performance and business performance in SMEs. To fulfil the research aim, quantitative research was carried out among 112 Czech electrotechnical SMEs. The findings show that the higher the rating companies give to working with external customers, the less chance they have of providing smart services. Thus, SMEs who value cooperation flexibility with external customers as less important are more likely to provide smart services. The higher rating companies give to product innovation flexibility, the higher the chance for providing smart services. Thus, we can expect companies who value product innovation flexibility more highly to more likely deliver smart services.

Published: October 2020

Gummy candies are nutritionally poor foods; however, they have a large consumer market. Enhancing these products with nourishing and/or functional matrices is a challenge. This study aimed to develop the features of a gummy candy probiotic, containing Bifidobacterium lactis HN019, and evaluate its effectiveness in inhibiting Streptococcus mutans UA159. The candy was suitable for probiotic development, whose viable bacterial count was 8.54 Log CFU/g in the ready-to-eat product; high viability was maintained during the 28-day shelf life. Additionally, the rate of probiotic survival under in vitro gastrointestinal simulation was 98% and 93% in the ready-to-eat product and after shelf life, respectively. The sensory analysis revealed scores over 8.0 in all attributes evaluated. Lastly, the inhibition test of S. mutans UA159 showed 25% and 98% inhibition, with 10% and 20% xylitol respectively. Probiotic and xylitol gummy candy is a potential functional food and can target a niche food market, such as teenagers.

Use of trifoliate orange [Poncirus trifoliata (L.) Raf.] as a rootstock has intensified in recent years in Brazil. Objectives of this study were to evaluate the effects of lime and agricultural gypsum on concentration of nutrients in trifoliate orange. Seedlings of trifoliate orange were grown in PVC pipe columns, presenting 15 cm in diameter and 35 cm in length. The columns were sectioned in two rings: the upper ring, 15 cm high, and the lower ring, 20 cm high. The factorial scheme (2×4)+1 was used, being two liming treatments and four agricultural gypsum doses (carried out only in the soil of the upper ring), and an additional treatment (with liming carried out in the soil of both upper and lower ring). Liming increased Mg and S concentrations in roots of the superficial soil layer (0-15 cm). Ca concentration was higher in roots of both superficial (0-15 cm) and subsuperficial (15-35 cm) layers. Gypsum without liming resulted in higher N, K, and Mn concentrations and lower Mg concentration in roots of the soil subsurface layer. Ca and S concentrations in root of the soil superficial layer were higher with gypsum. In plant shoot, the concentrations of K, Ca, S and Cu were higher with liming, and concentrations of Ca and P were higher and lower, respectively, with gypsum application.

Published: October 2020

This study aimed to develop a device for traceability of the goods delivery process, using radio frequency technology (RFID), which will inform the date, time and location where the goods are being delivered to the end customer. The methodology used consisted of three stages: 1) data collection through a portable collector along with RFID tags, 2) data processing by the microcontroller and 3) carrying out the consultation of the information contained in the tag through the communication between the RFID and the Arduino, whose product traceability was carried out through radio frequency sending information via GSM; while the materials used were 1 mega arduino board, 1 6m Neo GPS shield, 1 Sim 900 module, 1 RC522 RFID reader, 1 16x2 graphic LCD display and 1 keychain RFID tag. For testing the sending of date, time, product specifications and location information via SMS to the registered cell phone at the time of product delivery, operations were carried out in different locations with different dates and times and the messages were sent without fail. The results confirmed the display of the information “Data Collected Successfully” on the LCD display, after the reading of the LCD label by the collector. The proposed prototype proved to be effective, managing to control the delivery of low-cost goods through passive tag on a portable RFID reader.

Published: October 2020

Os autores buscaram alterações ósseas nas costelas de 12 ossadas obtidas da exumação de cadáveres de um cemitério público de Cascavel-PR, que foram doadas à universidade para fins didáticos e de pesquisa. Nessa verificação, observou-se a presença de uma protuberância óssea de 0,7 mm de comprimento e 0,4 mm de espessura na região intratorácica de uma costela do antímero direito. Esse achado é compatível com o quadro de exostose solitária e se apresenta em um local raro de acometimento. A presença desse achado pode levar indivíduos a apresentarem dores ou desconfortos torácicos, uma vez que a compressão promovida por essa estrutura é incômoda, ou pode ser assintomática e de diagnóstico casual. Além disso, pode, eventualmente, levar a quadros graves como o pneumotórax, hemotórax, compressão neural e até degeneração sarcomatosa. Dessa forma, a investigação profissional nesses indivíduos pode ser necessária a fim de evitar complicações futuras.

O trabalho objetiva avaliar o quanto as espécies parasitas são capazes de comprometerem o crescimento, a floração e a produtividade das plantas hospedeiras. Trata-se de um estudo de revisão bibliográfica realizada em artigos, dissertações e monografias publicados nos anos de 1987 a 2020, a busca ocorreu nos Periódicos Capes, Google Acadêmico, SciELO e em livros da área de interesse, os descritores utilizados foram Plantas parasitas, Plantas hospedeiras e Interações parasitárias, após a leitura dos títulos e dos resumos, foram selecionados 62 obras lidas na língua portuguesa e inglesas para a elaboração deste manuscrito. Através da revisão bibliográfica, tornou-se possível compreender e analisar a relação das espécies parasitas com as espécies hospedeiras, o parasitismo tem ocorrência tanto na parte aérea como subterrâneas, na parte aérea classifica-se em halo e hemiparasitas, enquanto nos órgãos subterrâneos tem como agentes parasitários os nematoides, capazes de ocasionarem danos no crescimento e desenvolvimento dessas espécies, decorrente a retirada intensa de nutrientes e água, resultando no desencadeamento de doenças classificadas em infecciosas/bióticas ou não infecciosas/abióticas. Os ataques provenientes de espécies parasitas, induzem que a espécies hospedeiras gerem seu próprio sistema de defesa, pela formação de barreiras físicas e biológicas, ao sobreviverem são capazes de possuírem a Resistência Sistêmica Adquirida (RSA) e a produção de compostos pelo metabolismo secundário. Portanto, as espécies parasitas são capazes de gerarem danos diretos no crescimento, na floração e na produtividade das espécies hospedeiras, que somente é revertida quando o vegetal gera defesa subsequente, afim de garantir a existência da espécie no meio.

Whether variation of winter migration distance among individuals within a population has consequences on their reproductive performance has rarely been assessed. Using individual global location sensor-tracking, we determined variation in migration distance, and its breeding consequences, in a Svalbard colony of the little auk Alle alle, a high-Arctic seabird with high flight costs. We found 2 distinct wintering quarters (north of Iceland and SW Greenland) implying a 2-fold difference in migration distance (1500 vs. 3100 km on average from the colony). This migration route from Svalbard to Greenland is among the longest recorded distances for an alcid species. Birds travelling a longer distance were more likely to be females and smaller, but more importantly, migration strategy had no apparent effect on reproductive performance (either timing or success). Our results contradict predictive studies which suggested that the establishment of migration routes to different winter destinations may be limited by the energetic constraints of flight. Our results show that a longer migration route does not necessarily have carry-over effects on subsequent reproduction.

Published: October 2020

An anode bimetallic catalyst comprising Ni-Pd alloy nanoparticles was loaded on acid-treated multi-walled carbon nanotubes (MWCNTs) for application in a direct urea fuel cell. The bimetallic catalyst and MWCNTs were synthesized by a hydrothermal method at 160°C for 5 h. To reduce the catalyst particle size, alkaline resistance, and facilitate their uniform distribution on the surface of the MWCNTs, phosphorus (P) was added to the Ni-Pd/MWCNT catalyst. The effects of P on the distribution and reduction in size of catalyst particles were investigated by Brunauer–Emmett–Teller analysis, transmission electron microscopy, and X-ray diffraction analysis. The enhanced catalytic activity and durability of the P-containing catalyst was confirmed by the high current density [1897.76 mA/cm2 (vs. Ag/AgCl)] obtained at 0.45 V in a 3 M KOH/1.0 M urea alkaline aqueous solution compared with that of the catalyst without P [604.87 mA/cm2 (vs. Ag/AgCl)], as determined by cyclic voltammetry and chronoamperometry. A Urea–O2 fuel cell assembled with a membrane electrode assembly comprising the Ni-Pd(P)/MWCNT catalyst delivered peak power densities of 0.756 and 3.825 mW/cm2 at 25 and 60°C, respectively, in a 3 M KOH/1 M urea solution.

In this work, we studied the effect of three glyphosate formulations (isopropylamine, ammonium and potassium salts) and two non-ionic adjuvants on the resistance response of two resistant (R1, R2) and one susceptible population of the highly invasive Asteraceae, Conyza sumatrensis, from Southern France vineyards. Only in R1, an amino acid substitution (Pro106Thr) was found in the enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS). The two adjuvants, in a similar fashion, significantly reduced GR50 values for every population and glyphosate formulation. Without adjuvants, glyphosate as potassium salt was the only formulation able to significantly reduce the GR50 values of every population. For every population, the two adjuvants improved, indistinguishably, leaf retention of the herbicidal solution and the potassium salt formulation led to the highest retention, both with and without the adjuvant added. Uptake responses paralleled those of retention and adjuvant addition was more effective in increasing foliar uptake of the lower performing formulations (isopropylamine and ammonium salts). The allocation pattern of glyphosate among plant compartments was only dependent on population, with R2 retaining most glyphosate in the treated leaf, clearly suggesting the occurrence of a Non-Target Site Resistance (NTSR) mechanism. Results indicate that control of weed populations possessing NTSR mechanisms of resistance to glyphosate may be improved through adequate selection of formulation and adjuvant use.

While free-range laying hens frequently experience health and welfare challenges, the contribution of range use towards these risks are largely unknown. The aim of this pilot study was to investigate the survival, health and welfare of commercial free-range laying hens and explore the association with early range use. Range use of 9375 Lohmann Brown hens housed within five flocks was assessed during 18–21 weeks of age and individual hens were classified as “rangers” (frequent range users), “roamers” (intermittent range users), and “stayers” (rare/no range users) were then subject to necropsy at 74 weeks of age. Rangers and roamers were three times and 2.4 times more likely to survive than stayers, respectively (p = 0.001). Overall, rangers had significantly better feather cover and more lesions associated with spotty liver diseases compared to roamers and stayers (p = 0.001). Similarly, rangers and roamers had a higher prevalence of A. galli infection and less frequent signs of fatty liver syndrome compared to stayers. Rangers had a higher proportion of hens with full ovary follicle production compared to stayers and roamers (p = 0.035). This information is highly relevant to consider the targeted support of different flock subpopulations to improve hen health and welfare, directly affecting farm profitability. Further research on other farms is warranted to investigate the transferability of the observed results.
Dreaming about Dogs: An Online Survey

Dogs have been close human companions for millennia and one would expect—according to the continuity hypothesis of dreaming—that dogs are also quite common in dreams. Previous studies showed that the percentages of dreams that include dogs range from about 1.5% to 5%, but studies relating waking-life experiences with dogs with dreams about dogs have not been carried out. In total, 1695 persons (960 women, 735 men) completed an online survey that included questions about dreams and waking-life experiences that included dogs. The findings indicate that dogs show up, on average, in about 5% of remembered dreams, but this percentage is much higher in the dreams of dog owners and persons with close contacts with dogs. Moreover, the active time spent with a dog and the proximity during sleep is also related to a higher percentage of dreams that include dogs. Although dreams including dogs are on average more positively toned than dreams in general, about 11% of the dog dreams included threatening dogs. Persons who had negative experiences with dogs in their waking lives reported more threatening dog dreams. The results support the continuity hypothesis and it would be very interesting to conduct content analytic studies with dream samples obtained from dog owners to learn more about the variety of interactions between dreamers and dogs.

Euthanasia is a critical component in swine production and veterinarians play an important role in euthanasia protocol development and training. This study aimed to understand veterinarian involvement in and perspectives on euthanasia on pig farms. An online survey was disseminated both at a pig welfare conference and online via a veterinarian e-newsletter. Twenty-five veterinarians participated in the survey. The majority of respondents indicated that caretakers are the individuals making euthanasia decisions and performing the task (n = 17, 68% and 22, 88%, respectively). The majority (22, 88%) of respondents indicated that most of the facilities with which they work have a written euthanasia protocol, and 72% (18) indicated that they assisted in protocol development. Only half of respondents (13, 52%) agreed that “all employees performing euthanasia have been trained adequately”, and 80% (20) identified an interest in delivering more training. Less than half the respondents indicated that strategies for coping with “personal stress” and “emotional wellness” (12, 48%) were included in euthanasia training. While the moral stress of performing euthanasia is recognized, there is opportunity for addressing mental well-being in euthanasia resources. Although preliminary, this study supports the need for further euthanasia training on-farm, involving veterinarians in the process.

Published: October 2020

Exhausted olive pomace (EOP) is the waste generated from the drying and subsequent extraction of residual oil from the olive pomace. In this work, the effect of different aqueous solvents on the recovery of antioxidant compounds from this lignocellulosic biomass was assessed. Water extraction was selected as the best option for recovering bioactive compounds from EOP, and the influence of the main operational parameters involved in the extraction was evaluated by response surface methodology. Aqueous extraction of EOP under optimised conditions (10% solids, 85 ºC, and 90 min) yielded an extract with concentrations (per g EOP) of phenolic compounds and flavonoids of 44.5 mg gallic acid equivalent and 114.9 mg rutin equivalent, respectively. Hydroxytyrosol was identified as the major phenolic compound in EOP aqueous extracts. Moreover, these extracts showed high antioxidant activity, as well as moderate bactericidal action against some food-borne pathogens. In general, these results indicate the great potential of EOP as a source of bioactive compounds, with potential uses in several industrial applications.

The Internet of Things (IoT) is becoming a regular part of our lives. The devices can be used in many sectors, such as education and in the learning process. The article describes the possibilities of using commonly available devices such as smart wristbands (watches) and eye tracking technology, i.e., using existing technical solutions and methods that rely on the application of sensors while maintaining non-invasiveness. By comparing the data from these devices, we observed how the students’ attention affects their results. We looked for a correlation between eye tracking, heart rate, and student attention and how it all impacts their learning outcomes. We evaluate the obtained data in order to determine whether there is a degree of dependence between concentration and heart rate of students.
