A literatura infantil tem duplo destinatário: a criança (leitor) e o adulto (comprador), de modo que os paratextos externos tendem a se dividir entre ambos. Assim, visa-se, com base nos paratextos veiculados na primeira capa e na quarta capa de livros de narrativas por imagens, discutir quem é o público-alvo de obras literárias integrantes da Categoria 2 da Educação Infantil do PNBE 2014. Os livros Ladrão de galinhas, de Béatrice Rodriguez, e Calma, camaleão!, de Laurent Cardon são analisados com base em postulados de Genette (2009). Os resultados apontam a importância das mensagens paratextuais para a interpretação. Infere-se, a partir do estudo, que tanto a produção do livro como a mediação docente deve considerar os paratextos nos processos de formação do leitor.

O Transtorno do Espectro Autista (TEA) é caracterizado por déficits persistentes na comunicação e interação social, bem como padrões de comportamentos repetitivos e interesses restritos. O objetivo deste estudo foi verificar o efeito da aplicação de um programa de ensino por pais/cuidadores sobre o desempenho de seu filho. Participaram uma menina de 18 meses, com TEA, e sua cuidadora. Trata-se de pesquisa quase experimental, intrassujeitos, do tipo AB (linha de base, tratamento e follow-up). Foi conduzido um programa individualizado para ensinar a cuidadora a utilizar procedimentos lúdicos, visando promover a interação social e o aumento de turnos interacionais dos participantes. Os desempenhos foram registrados em sessões semanais de 40 min, por um ano. Os dados das respostas da cuidadora foram submetidos ao Tau-U. Esta estatística, não paramétrica, revelou que nem todas as respostas da cuidadora, na fase de intervenção, mostraram fortes efeitos do tratamento, enquanto outros atestaram a robustez do mesmo. Com 95% de probabilidade de acerto, os procedimentos de intervenção afetaram significativamente as seguintes respostas : “usar músicas infantis” e “fazer um comentário engraçado ou elogioso para que a criança voltasse a brincar”. Na fase de intervenção houve aumento considerável de iniciativas de Izabel e de respostas da cuidadora, assim como das diversas modalidades de respostas de ambas. Assim, o programa de formação da cuidadora influenciou de forma significante a frequência de turnos e as modalidades de respostas da criança; e que a intervenção, via cuidadora, orientada por profissional, pode ser efetiva e apropriada ao contexto socioeconômico brasileiro.
The Use of Hybrid Energy Storage Devices for Balancing the Electricity Load Profile of Enterprises

Published: May 2020

In this article, the authors consider the possibility of using a hybrid energy storage system to even out the load profile of the enterprise. Solving the problem of rational use of energy storage taking into account the initial variable load schedule will significantly reduce not only the cost of electricity consumption by the enterprise, but also the costs of its production. Detailed characteristics of batteries with various types of electrolytes and supercapacitors are given. A model of the active scheme of a hybrid electric energy storage system consisting of a lithium-ion battery and a supercapacitor unit with the corresponding characteristics is presented. The model was carried out by using the SimPowerSystems software in MatLab. During the simulation, the temperature and the aging effects and of the batteries were not taken into account. The selfdischarge parameter of the battery was also not presented. As a result of the simulation, discharge characteristics of supercapacitors and batteries were obtained based upon which the expediency of their combined use for leveling load profiles of various types was substantiated. The paper presents the results of the simulation of operating modes of a hybrid energy storage device, combining the advantages of two types of energy storage devices, as well as a diagram of delivered power to the network, corresponding to the specified parameters. The paper provides a mathematical description of the increasing power by hybrid storage system resulting from the combined use of supercapacitors and batteries. The paper presents the dependence of the power increase ratio on the frequency and the pulse current duty ratio, which proves that the maximum possible output power of the hybrid storage system can be several times greater than the power of a single battery having the same parameters.

Published: May 2020

Abstract
Background: The development of gingival recessions (GR) after orthodontic treatment (OT) is well described in the literature. However, there is a lack of information about the changes in pre-existing GR during OT. Methods: This retrospective study aimed to examine the change of GR before and after OT. Intraoral photographs of 993 patients treated with fixed appliances between 2005 and 2017 were evaluated. Patients who had at least one GR on the vestibular surface of maxillary/mandibular teeth mesial to first molars were included. GR was measured on good quality plaster models before and after OT. The change of GR (T0-T1) was categorised into the three groups: worsened, did not change and improved (this group consisted of GR, which became better but did not disappear, and fully healed, which disappeared after OT)). The change of GR by ≥0.5 mm was recorded. Statistical analysis was performed using SPSS Statistics (Version 22.0. Armonk, NY, USA). Results: Fifty-one (5.1%) patient had ≥1 GR before OT. Of them, 37 (72.5%) patients were included in the final analysis according to the inclusion criteria. GR before OT was found on 114 buccal/labial surfaces. At tooth level the median GR improvement was 0.55 (Q1; Q3: 0.12; 0.96) mm (p<0.001). GR improved in 67 teeth (58.7%), did not change in 41 (36.0%), and worsened in 6 (5.3%). Of the 67 GR, which improved, full healing was observed in 15 (22.4%) teeth. There was a lower chance for GR improvement in cases with pre-treatment open bite (OR 3.35; 95% CI: 1.14, 9.84; p=0.03) and dental Class III patients (OR 2.20; 95% CI: 0.92, 5.28; p=0.03). Conclusions: Based on the findings of the present retrospective study, it may be concluded that orthodontic treatment induces changes in gingival recessions. In more than half of the teeth, the improvement in gingival recession was observed. Class III malocclusion and reduced pre-treatment overbite had a negative impact on GR improvement.
The impact of long dry periods on the aboveground biomass in tropical forests: 20 years of monitoring

Published: May 2020

Abstract
Background Long-term studies of community and population dynamics indicate that abrupt disturbances often catalyse changes in vegetation and carbon stocks. These disturbances include the opening of clearings, flooding, rainfall seasonality, and drought, as well as fire and direct human disturbance. Such events may be super-imposed on longer-term trends in disturbance, such as those associated with climate change (heating, drying), as well as resources. Intact neotropical forests have recently experienced increased drought frequency and fire, on top of pervasive increases in atmospheric CO 2 concentrations, but we lack long-term records of responses to such changes especially in the critical transitional areas at the interface of forest and savanna biomes. Here, we present results from 20 years monitoring a valley forest (moist tropical forest outlier) in central Brazil. The forest has experienced multiple drought events and includes plots which have and which have not experienced fire. We focus on how forest structure (stem density and aboveground biomass carbon) and dynamics (stem and biomass mortality and recruitment) have responded to these disturbance regimes. Results Overall, the biomass carbon stock increased due to the growth of the trees already present in the forest, without any increase in the overall number of tree stems. Over time, both recruitment and especially mortality of trees tended to increase, and periods of prolonged drought in particular resulted in increased mortality rates of larger trees. This increased mortality was in turn responsible for a decline in aboveground carbon toward the end of the monitoring period. Fire in 2010, which occurred in only some of our plots, tended to exacerbate the trends of increasing mortality and losses of biomass carbon. Conclusion Prolonged droughts influence the mortality of large trees, leading to a decline in aboveground carbon stocks. Here, and in other neotropical forests, recent droughts are capable of shutting down and reversing biomass carbon sinks. These new results add to evidence that anthropogenic climate changes are already adversely impacting tropical forests.
Identification and validation of a commercial cryopreservation medium for the practical preservation of Dirofilaria immitis microfilaria
Authors: Shirozu Takahiro , Soga Akira , Fukumoto Shinya 
Published: May 2020

Abstract
Background Dirofilaria immitis is a parasitic nematode transmitted by mosquitoes and the cause of heartworm disease in dogs and dirofilariasis in humans and other mammals. The parasite is endemic worldwide. Vector stage research requires a reliable supply of D. immitis microfilariae (mf). It is believed that cryopreserved mf would retain viability and provide a powerful tool for vector stage research. However, reports on cryopreservation of D. immitis mf are limited. Therefore, this study aimed to validate commercial cryopreservation media to establish a practical, convenient, and reproducible storage procedure for D. immitis mf. Methods Six different commercially available cryopreservation media were compared with the traditional polyvinylpyrrolidone-dimethyl sulfoxide (PVP-DMSO) preservation solution. In vitro viability of purified D. immitis mf and mf-infected total blood was analyzed using a motility assay and propidium iodide staining. In vivo infectivity of Aedes aegypti mosquitoes with cryopreserved mf was assessed using a mosquito survival test and quantifying the number of infective third stage larvae (L3) after 13 d post-infection. Results Purified mf cryopreserved in CultureSure showed the best viability when compared to mf cryopreserved in the remaining five commercially available media and PVP-DMSO. Viability of mf in mf-infected total blood cryopreserved in CultureSure varied with the ratio of infected blood to CultureSure. Optimum results were obtained with 200 µL mf-infected blood:800 µl CultureSure. CultureSure was also the optimum medium for cryopreserving mf prior to infectivity of Ae. aegypti. The number of L3 was approximately the same for CultureSure cryopreserved mf (3×-concentrated solution) and non-cryopreserved fresh mf. Conclusions CultureSure is an optimal commercial cryopreservation solution for the storage of D. immitis purified mf, mf-infected total blood, and mf used for in vivo mosquito experiments. Furthermore, this study describes an easy preservation method for clinical D. immitis -infected blood samples facilitating vector stage studies, as well as the education of veterinarians.

Abstract
Introduction Health technology assessment (HTA) is an effective tool to support priority setting and generate evidence for decision making especially en route to achieving universal health coverage (UHC). We assessed the capacity needs, policy areas of demand, and perspectives of key stakeholders for evidence-informed decision making in Nigeria where HTA is still new. Methods We surveyed 31 participants including decision makers, policy makers, academic researchers, civil society organizations, community-based organizations, development partners, health professional organizations. We revised an existing survey to qualitatively examine the need, policy areas of demand, and perspectives of stakeholders on HTA. We then analyzed responses and explored key themes. Results Most respondents were associated with organizations that generated or facilitated health services research. Research institutes highlighted their ability to provide expertise and skills for HTA research but some respondents noted a lack of human capacity for HTA. HTA was considered an important and valuable priority-setting tool with a key role in the design of health benefits packages, clinical guideline development, and service improvement. Public health programs, medicines and vaccines were the three main technology types that would especially benefit from the application of HTA. The perceived availability and accessibility of suitable local data to support HTA varied widely but was mostly considered inadequate and limited. Respondents needed evidence on health system financing, health service provision, burden of disease and noted a need for training support in research methodology, HTA and data management Conclusion The use of HTA by policymakers and communities in Nigeria is very limited mainly due to inadequate and insufficient capacity to produce and use HTA. Developing sustainable and institutionalized HTA systems requires in-country expertise and active participation from a range of stakeholders. Stakeholder participation in identifying HTA topics and conducting relevant research will enhance the use of HTA evidence produced for decision making. Therefore, the identified training needs for HTA and possible research topics should be considered a priority in establishing HTA for evidence-informed policy making for achieving UHC particularly among the most vulnerable people in Nigeria.

Published: May 2020

Abstract
Background
Several studies on the relationship between morphological parameters and traumatic diseases of the knee have already been conducted. However, few studies focused on the association between knee morphology and posterior cruciate ligament (PCL) avulsion fracture in adults. The objective of this study was to evaluate the impact of knee morphology on PCL avulsion fracture and determine risk factors in men and women separately.
Methods
A retrospective case-control study of 48 patients (comprised 25 men and 23 women) with PCL avulsion fracture compared with 48 age- and sex-matched controls was performed from 2012 to 2018. MRI measurements of the knee were acquired in the sagittal, coronal, and axial sequences. The assessed measurements including intercondylar notch width index, medial/lateral posterior tibial slopes, and coronal tibial slope were compared between case and control groups in both women and men. Univariable and binary logistic regression analyses were used to identify independent risk factors that were associated with PCL avulsion fracture.
Results
When female patients were analyzed, the notch width index (coronal) was significantly smaller, and the lateral posterior tibial slope was significantly higher in the case group. The binary logistic regression analysis showed that the notch width index (coronal) (B = -0.307, OR = 0.735, p = 0.025) was found to be an independent factor. When male patients were analyzed, no radiographic parameter was found to have a statistical difference between the case and control groups.
Conclusions
Notch width index (coronal) and lateral posterior tibial slope were found to affect PCL avulsion fracture in women, but no such measurements affected the PCL avulsion fracture in men. Furthermore, a smaller notch width index (coronal) in women was found to be a risk factor in PCL avulsion fracture.
Gender differences in attrition rates of hospital-based medical specialty programs: attributable to gender composition of the clinical specialty?
Authors: Butterman Olivia , Slenter Victor , Velden Lud Van der , Batenburg Ronald 
Published: May 2020

Abstract
Background

Since 1999 the Advisory Committee on Medical Manpower Planning (ACMMP) advises the Dutch government on the medical workforce capacity and the intake in training programs, as to achieve or maintain a balance on the labour market. One of the key parameters the ACMMP uses when calculating the required intake in training programs, is the attrition rate.
Methods

In total 11,579 trainees enrolled in hospital-based programs from January 1st 2003 until 31st of December 2012, for 26 specialisms. To explore possible explanations for the gender differences in attrition rate per specialty, additional information was gathered: the percentage of males per program, the total number of specialists in training, the duration of the training and the percentage of males currently working in that specialty.
Results

One training program was excluded, due to the small size of that training program (62 trainees) and the large outliers it produced. Regression analyses were done, showing significant explanations of the variation in the difference between male and female attrition rates (Y1), for the proportion of males working in the profession per 01-01-2003 (R2: .545, F(27,60), p < .000), the proportion of males in training per 01-01-2003 (R2: .417, F(16,01), p < .000) and a small effect for the relationship with the total attrition rate for each training program (R2: .163, F(4,46), p < .046). There was also a significant effect for the duration of the specialty training (R2: .299, F(9,85), p < .005). A Kruskal-Wallis test was preformed to analyse the difference in attrition by type of specialty. The difference between the types of specialisms were significant (H = 6,66, p. 0,036).
Conclusions

Attrition rates in Dutch hospital-based specialty programs differ between males and females in a way that more males tend to drop-out from training when the specialty is dominated by women and, importantly, vice versa as well. The relationships found needs to be explored, in particular as the duration and nature of the specialty training seem to interact with gender ratios in the training programs and occupations longer training programs tend to have more males on them. Furthermore, more insight is needed in the selection and identification processes among residents in specialty training.
