This article addresses the development of an Augmented Reality (AR) system as a tool for teaching and learning architectural design. The research brings reflection on a work of theoretical and practical assessment, product of the investigation of a Masters in Professional and Technological Education (PROFEPT) offered by the Federal Institute of Education, Science and Technology of Ceará (IFCE), proposed by Silva [1], where professors and students of the Technical in Buildings course evaluated the effectiveness of the proposal. As an educational product of the research, an ebook was developed, where AR resources allied to the project are present. This product represents a support tool for teachers and students to overcome the difficulties encountered in the discipline of architectural design. In addition, the ebook assumes great efficiency and applicability for remote classes as well. Thus, this article describes the study and the results of research carried out using AR, in addition to proposing new possibilities for integrating AR into teaching and learning processes.

ABSTRACT. The objective was to evaluate the performance, egg quality, thermoregulation, body morphology and behavior of different categories of laying poultry. Two treatments with two genetic groups were used, 50 birds of the Hisex Brown strain and 50 birds of the Black Avifran chicken breed with 55 weeks, distributed in a completely randomized design with 10 replicates and 5 birds in each experimental unit. The variables egg weight, weight and percentage of albumen, yolk and shell, marketable eggs, specific gravity, color b *, egg / poultry production day-1 were not different (p > 0.05) between the two groups. Feed conversion by egg mass and dozen eggs, yolk color, L color, diameter, height, shell color presented a difference (p < 0.05), being higher values for the Black Avifran breed. The Black Chicken Avifran had higher body temperature; however, its performance and the quality of its eggs did not change. Black Chicken Avifran presented higher values in relation to body morphology, and better results in relation to the animal performance, therefore, it was more efficient, since it obtained a lower consumption and production equal to the lineage Hisex Brown, when created in the Cage - Free system.

A natação em águas abertas ganhou, nos últimos anos, um relevante número de adeptos. Por essa crescente busca, o presente estudo teve por objetivo descrever o perfil dos participantes de natação em águas abertas da cidade Fortaleza-Ceará. Participaram do estudo 50 praticantes de natação em águas abertas há, pelo menos, três meses de pratica, com idades entre 21 e 66 anos. Foi utilizado um questionário fechado, composto por 30 questões contendo questões dicotômicas, de múltipla escolha e de múltiplos gabaritos, e realizado através da ferramenta Google Docs®. A abordagem dos participantes ocorreu na orla de Fortaleza e, uma vez aceito o convite, o link do questionário era enviado por e-mail. Observou-se uma alta prevalência de pós-graduados, principalmente, entre as mulheres (73,3%). O prazer em nadar na natureza foi um objetivo bem relatado pelas mulheres (60%), enquanto os homens ficaram divididos entre o prazer em nadar na natureza (28,6%), competição (20%) e condicionamento físico (20%). Conclui-se que o perfil dos praticantes de natação em águas abertas da cidade de Fortaleza caracteriza-se por pessoas de renda e escolaridade mais altas, cujos objetivos estão relacionados ao condicionamento físico e ao prazer em praticar esportes junto à natureza.

Swimming in open water has gained, in recent years, a relevant number of fans. Due to this growing search, the present study had the objective of describing the profile of swimming participants in open water of Fortaleza-Ceará city. The study included 50 swimmers in open water for at least three months of practice, aged between 21 and 66 years. We used a closed questionnaire, composed of 30 questions containing dichotomous, multiple choice and multiple template questions, and carried out using the Google Docs® tool. The approach of the participants took place in the border of Fortaleza and, once accepted the invitation, the link of the questionnaire was sent by e-mail. There was a high prevalence of post-graduates, mainly among women (73.3%). The pleasure of swimming in nature was a goal well reported by women (60%), while men were divided between the pleasure of swimming in nature (28.6%), competition (20%) and physical conditioning (20%). It is concluded that the profile of open water swimmers in the city of Fortaleza is characterized by people of higher income and education, whose objectives are related to physical conditioning and to enjoy sports with nature.

O presente estudo teve como objetivo averiguar todo o processo do tiro de penalty no âmbito técnico e cinemático. Trata-se de um estudo observacional transversal de caráter quali-quantitativo, realizado com 6 atletas de pólo aquático do Náutico Atlético Cearense, com idades entre 16 a 19 anos de nível nacional, através da captura de imagens cinematográficas de cada tiro de penalty realizado, para uma posterior análise no software DARTFISH 5.0, de acordo com uma ficha padrão de análise quantitativa e qualitativa do desempenho técnico. Utilizou-se um “macacão” na cor preta cujo ombros, cotovelos e punhos foram demarcados na cor branca. Cada um cobrou 5 tiros de penalty. A análise estatística dos dados foi feita através dos programas Graphpad Prism 3.0, foi utilizado média e erro padrão da média, variância e ANOVA, seguida de Tukey com exposição de gráficos. Os jogadores que atingiram maiores velocidades médias em comparação com os demais, foram os que menos obtiveram variações nos parâmetros, porém apenas a altura atingida pelo corpo do jogador sob a superfície da água, parece ser decisivo na eficiência e potência do tiro de penalty.

The present study had as objective to investigate the whole process of the shot of penalty in the technical and kinematic scope. This is a cross-sectional observational study of a qualitative and quantitative character, carried out with 6 aquatic athletes from Náutico Atlético Cearense, aged between 16 and 19 years of national level, through the capture of cinematographic images of each shot of penalty taken, for further analysis in DARTFISH 5.0 software, according to a standardized quantitative and qualitative technical performance data sheet. A black "overalls" was used whose shoulders, elbows and wrists were demarcated in the white color. Each one took five penalty shots. Statistical analysis of the data was done through the Graphpad Prism 3.0 programs, using mean and standard error of the mean, variance and ANOVA, followed by Tukey with graphical exposition. The players who achieved higher average velocities compared to the others, were the ones that obtained the least variations in the parameters, but only the height reached by the player's body under the surface of the water seems to be decisive in the efficiency and power of the penalty shot.

In the search for new larvicides from plants, we have investigated the potential activity of the rotenoids deguelin (1), 12a-hydroxy-α-toxicarol (2) and tephrosin (3), isolated from the bioactive ethanol extract of roots of Tephrosia toxicaria Pers., against Aedes aegypti, the main vector of dengue. The absolute configuration of these compounds was determined by circular dichroism (CD) spectra. The LC50 values of the compounds evaluated justify the potential of T. toxicaria as a new natural larvicide.

The ethanol extracts from leaves, stems, pods and roots were assayed against the 3rd instar Aedes aegypti larvae and the highest activity was observed in the roots extracts (LC50 47.86 ppm). This extract was submitted to partition with hexane, chloroform, ethyl acetate and methanol. The respective fractions were bioassayed and the best larvicidal activities were identified in the hexane (LC50 23.99 ppm) and chloroform (LC50 13.80 ppm) fractions. Antioxidant activity (DDPH method) was observed in the ethanol extract (IC50 276 µg/mL) from roots of T. toxicaria. Fractions from this extract were also tested and the highest antioxidant activity (IC50 89 µg/mL) was found in the methanol fraction. The flavonoids iso-obovatin (1), obovatin (2), 6a,12a-dehydro-β-toxicarol (3), 6a,12a-dehydro-α-toxicarol (4) and α-toxicarol (5) were isolated and bioassayed against A. aegypti. The flavonoid 5 showed the best larvicidal activity (LC50 24.55 ppm). The antioxidant activity of 2 was investigated and showed IC50 3.370 µg/mL. The antioxidant and larvicidal activities of Tephrosia toxicaria are reported for the first time.
