ABSTRACT The use of non-conventional feeds in poultry farming can reduce production costs, mainly because of its low cost, availability and chemical composition. Thus, parboiled whole rice bran (PWRB) appears as a potential use in feeding quails. Two experiments were carried out to evaluate the effects of the inclusion of PWRB in the diet of quails. In each experiment, a total of 288 seven-day-old European quails of both sexes, were distributed in a completely randomized design with six treatments and six replicates of eight quails each. The treatments consisted in the inclusion of PWRB in the proportions of 0; 5; 10; 15; 20 and 25% (first) and 0; 8; 16; 24; 32 and 40% (second). In the first experiment, a linear reduction in feed intake and weight gain was observed with the inclusion of PWRB above 5%, with no significant effect on feed conversion and carcass characteristics. However, there was no loss in the performance and carcass characteristics of quails fed with different levels of PWRB in comparison to the control group. In the second, it was observed that the inclusion of PWRB above 8% promoted a linear reduction in feed intake, weight gain and improvement in feed conversion, with no significant effect on carcass characteristics. However, quails fed 40% PWRB showed reduced intake and weight gain when compared to the control group. The use of PWRB provided an improvement in economic viability. Considering the effect on growth, PWRB can be used in the feeding of meat quails up to 32%.

Abstract The objective of this work was to evaluate the effect of the dietary addition of calcium anacardate as a source of phenolic compounds on the reproductive performance and blood antioxidant parameters of New Zealand White female rabbits. Twenty-seven New Zealand White female rabbits were distributed in a randomized complete block design with three treatments and nine replicates, considering one animal as the experimental unit. The treatments consisted of pelleted diets with different inclusion levels of calcium anacardate (0, 0.5, and 1.0%). The inclusion of calcium anacardate in the diets increased the concentration of phenolic compounds and the antioxidant capacity in the blood of lactating female rabbits. Calcium anacardate at the level of 1.0% improves the feed conversion ratio during gestation and increases the phenolic compounds and antioxidant capacity in the blood serum of female rabbits at 21 days of lactation.

Abstract Surge arresters are at the forefront of protection against voltage surges. The loss of the protective effect of surge arresters imposes accidents and unplanned shutdowns on the power system. It directly affects the interruption of power supplies and imposes fines on service providers. Monitoring and diagnostics in the lightning rod field require studies and work that present the degradation behaviour of surge arresters to help develop and improve existing techniques. This paper presents the development of a laboratory with a low-energy, mobile current waveform impulse generator. It allows for conducting aging tests by applying discharges to low-voltage zinc oxide surge arresters used in the energy distribution sector. Samples of surge arresters were subjected to the discharges produced by the developed generator, and they exhibited degradation, thus showing asymmetry between the positive and negative half-cycles of leakage current. surges system providers techniques lowenergy, lowenergy low energy, low-energy generator lowvoltage sector halfcycles half cycles

ABSTRACT Lippia dulcis is a medicinal species used by communities in the Amazon region for the control of diabetes and as a tranquilizer. The objective of this study was to evaluate the plant biomass production, antioxidant defense, and chemical profiles of the phenolic compounds and essential oil of plants grown under different doses of cattle, quail, and chicken manure. Chicken and quail manure at a dose of 6 kg m-2 reached the highest values of dry weight and essential oil yield of the leaves and positively influenced bisabolol production. Cattle manure affected the content and yield of the essential oil of the inflorescences, the antioxidant defense performance, and the chemical composition of phenolic compounds and essential oil. Plants grown with cattle manure showed a linear increase in the amounts of these substances with increasing dose. Chicken and quail manure led to the highest values of these components at doses between 0 and 3 kg m-2. The evaluation of phenolic compounds and antioxidant defense showed the highest values at doses of 0, 1.5, and 3 kg m-2, regardless of the manure used. The essential oil concentration was higher in the inflorescences, and its total yield was higher in the leaves. The chemical composition varied between these vegetative organs. tranquilizer production m2 m 2 m- inflorescences performance m2. 2. 15 1 5 1.5 m2, 2, organs 1.

Abstract With the growing demand for solutions to prevent and resolve faults in gas-insulated substations that affect the operation of the electrical system, a fault simulation laboratory for gas-insulated substations was developed to develop solutions for monitoring and locating these faults. The laboratory is composed of instruments for a fault location system based on traveling wave theory. The laboratory also has computational programs for fault simulation control and signal acquisition, in addition to having tools to analyze the data. The results were obtained through tests carried out that confirmed the laboratory's ability to simulate the operation of faults in gas-insulated substations, which allowed demonstrating the capacity of the fault location system using the theory of traveling waves. gasinsulated gas insulated acquisition data laboratorys s waves

Abstract This paper presents the strategies and initial implementations of a data culture conversion process at a company in the electricity sector. Solutions are being developed within the scope of the construction management macro-process, which involves multiple sectors of the company, as well as external agents. The strategy is based on implementing Proofs of Concept as tools for converting the data culture within the company and, at the same time, supporting the essential activities of construction management. The proofs of concept aligned with the change in data culture have two components: technology and people. The first consists mainly of intelligent automation and process optimization. The second component involves sensitization, training and developing solutions together with the company's employees. The results involve a reduction in workload since some activities have been partially or totally transferred to the software. Greater assertiveness in estimating numerical data, such as prices and budgets. Increased reliability by reducing human intervention and complex calculations. Greater controllability by monitoring multiple activities and sectors, simplifying management. Finally, the integration of technology and people has shown significant advances in organizational culture, enabling employees to have a greater understanding of advanced tools and methods and to be able to identify opportunities and share solutions within the company. sector macroprocess, macroprocess macro process, macro-process agents time components optimization sensitization companys s software budgets calculations Finally

ABSTRACT Sunflower cake is an alternative feed with nutritional potential to be used in poultry feeding. However, the high fiber content and the presence of antinutritional factors can compromise the availability of nutrients in the diet and influence the bone development of pullets, which can be mitigated with the dietary inclusion of exogenous enzymes. In this context, the objective of this study was to evaluate the effect of multi-enzyme supplementation in rations containing sunflower cake to pullets on mineral digestibility and quality and bone mineral composition. A total of 1020 pullets 7-weeks-age from the commercial strain Hy-Line, 540 white pullets and 480 brown pullets, were distributed in a randomized experimental design in a 2×2+1 factorial arrangement, with two sunflower cake levels (10 and 20% for white pullets and 12 and 24 % for brown pullets); two ways of enzymatic supplementation (absence and presence of multi-enzyme complex), and one control diet based on corn and soybean meal, totaling five treatments with six replicates of 18 white pullets and 16 brown pullets. Between week 14 and week 15, a metabolic trial was performed to determine the digestibility coefficient of ration minerals. To assess bone quality of the tibia and femur, one pullet of the 12th and 17th week of age was selected and killed. There was no significant interaction between the tested factors (sunflower cake x multi-enzyme complexes) for any of the variables studied. The inclusion level of sunflower cake did not influence the growth and bone quality parameters of the pullets during the growing phase. However, a presence of the multi-enzyme complex provided significant improvements in Ca, P and Mg digestibility coefficient. It is concluded that the multi-enzyme supplementation in the diets increases the digestibility of the mineral in the rations, contributing to the maintenance of bone quality of pullets fed with up to 24% sunflower cake. feeding However enzymes context multienzyme multi enzyme composition 102 7weeksage weeksage 7 weeks HyLine, HyLine Hy Line, Line Hy-Line 54 48 221 2 1 2×2+ arrangement 10 (1 20 pullets) absence complex, , complex) meal 15 minerals femur th killed complexes studied phase Ca 5 4 22 2×2 ( 2×

RESUMO A torta de girassol é um alimento alternativo com potencial nutricional para ser usado na alimentação de aves. Contudo, o elevado teor de fibras e a presença de fatores antinutricionais pode comprometer a disponibilidade dos nutrientes da dieta e influenciar o desenvolvimento ósseo de frangas, o que pode ser mitigado com a inclusão dietética e enzimas exógenas. Nesse contexto, o objetivo da pesquisa foi avaliar o efeito da suplementação multienzimática em rações contendo torta de girassol para frangas sobre a digestibilidade dos minerais da ração e a qualidade e composição mineral óssea. Um total de 1020 frangas com 7 semanas de idade da linhagem comercial Hy-Line, 540 frangas leves e 480 frangas semipesadas, foram distribuídas em delineamento experimental inteiramente casualizado em esquema fatorial 2×2+1, sendo dois níveis de torta de girassol (10 e 20% - para frangas brancas e 12 e 24% para frangas vermelhas), duas formas de suplementação enzimática (com e sem complexo enzimático) e um tratamento controle à base de milho e farelo de soja, totalizando cinco tratamentos com seis repetições de 18 frangas brancas e 16 frangas vermelhas. Entre a 14ª e 15ª semana, foi realizado ensaio de metabolismo para determinar o coeficiente de digestibilidade dos minerais das rações. Para avaliação da qualidade óssea da tíbia foi selecionada e abatida uma ave por parcela na 12ª e na 17ª semana de idade. Nos dois ensaios, não houve interação significativa entre os fatores testados para todas as variáveis estudadas. A inclusão da torta de girassol não influenciou significativamente na digestibilidade dos minerais e os parâmetros de crescimento e qualidade óssea das frangas. Por sua vez, a presença do complexo multienzimático proporcionou melhora significativa na digestibilidade dos minerais, sem influenciar os parâmetros ósseos. Conclui-se que a suplementação multienzimática nas rações aumenta a digestibilidade dos minerais da ração, contribuindo para a manutenção da qualidade óssea de frangas leves e semipesadas alimentadas com até 20% e 24% de torta de girassol, respectivamente. aves Contudo exógenas contexto 102 HyLine, HyLine Hy Line, Line Hy-Line 54 48 221 2 1 2×2+1 10 (1 20 24 vermelhas, vermelhas , vermelhas) enzimático soja ª ensaios estudadas vez ósseos Concluise Conclui se respectivamente 5 4 22 2×2+ ( 2×2 2×

Abstract Shielded substations with SF6 gas insulation (GIS) play a critical role in supplying power to urban areas, and it is crucial to quickly identify and isolate faults to restore system operation and meet supply demands. However, locating faults in such substations can involve extensive and time-consuming procedures, such as opening and closing hermetically sealed compartments containing SF6. This paper presents the development of an acoustic test bench that accurately replicates the dynamic characteristics of SF6 shielded substations. By utilizing the traveling wave technique, partial discharges occurring in high-voltage insulation can be detected and precisely located. The method employs various techniques, including the analysis of the arrival time of traveling waves at different points within the substation and triangulation methods. The use of traveling waves in partial discharge detection offers several advantages, such as precise fault location and non-interference with normal substation operations. Additionally, acoustic methods are highly sensitive to other sources of partial discharges, such as moving particles and fluctuating potential discharges. The results demonstrate that the combination of the acoustic test bench and the disturbance localization technique presents an innovative approach to fault location studies in GIS. The acoustic test bench enables controlled simulation of failure conditions, providing accurate data on the acoustic behavior of substations. Through the disturbance location technique, these data can be analyzed and interpreted to pinpoint the exact fault location. This integrated approach enhances the efficiency of the troubleshooting process and reduces the time required to repair GIS.

Abstract As high-voltage circuit breakers (HVCBs) are responsible for switching off the load in the event of anomalies, they suffer various wear and tear, both on their main contacts and on the other actuation mechanisms. Not only load maneuvers but also weather conditions can bring factors that contribute to deterioration and, consequently, contribute to failures of this component that is so important for energy supply. Both failures and maintenance shutdowns generate costs for substations, something that could be minimized if there was monitoring of the condition of the HVCBs. This paper shows a methodology to analyze the vibration signal of HVCB in order to identify and quantify contact failures. The proposed methodology is verified through an experimental setup. The results show that it is possible not only to identify the fault but also to assess its intensity using vibration analysis. highvoltage high voltage HVCBs (HVCBs anomalies tear mechanisms consequently supply substations setup analysis

Abstract We examined the effects of including sunflower cake (SC) associated with an enzyme complex (EC) in the diet of meat quails on nutrient metabolism, performance, carcass characteristics, bone parameters and economic viability. In total, 432 meat quails (7 to 42 days old) were assigned to six treatments in a completely randomised design with 6 replicates with 12 birds each. A 2 × 3 factorial arrangement was adopted (two levels of SC: 10 and 20%; three diet formulation strategies: normal, reduction in the nutrient and energy matrix considering the enzymatic contribution and reduced diet with EC). No interaction effect was observed. The increased levels of SC from 10% to 20% promoted in decrease in the metabolisability coefficients of dry matter and gross energy and in the value of AMEn and increased relative weight of gizzard. The addition of EC in diets containing SC allows a better metabolization of nitrogen and energy, equalize to the normal diet. The best breast yield was obtained in the birds fed the reduced diet with EC, in relation to normal diet. The reduced diet and the reduced diet with EC provided the lowest cost of food and the best economic efficiency index. Up to 20% of the sunflower cake can be included in the diet of cut quail, with or without enzyme supplementation. However, the use of the enzyme complex composed of carbohydrases, proteases and phytase can favor the metabolization of nitrogen and energy from the diet containing sunflower cake.

Abstract Anacardic acid is naturally found in various parts of the cashew tree (Anacardium occidentale L.) and marketed as calcium anacardate. This product has antibacterial, antifungal and antioxidant activity, and has been used in humans in the treatment and prevention of cardiovascular and cerebrovascular diseases and tumors. In meat and egg production systems, anacardic acid is used as a substitute for growth-promoting antibiotics. The study objective was to evaluate effects of adding calcium anacardate as source of anacardic acid in laying Japanese quail diet on bird performance and eggs quality. A total of 252 Japanese quail with 22 week-old were studied, using a completely randomized design composed of six treatments with six replicates and seven quails per experimental unit. Treatments applied were: diet without growth promoter; diet with 0,1% growth promoter; and four diets without growth promoter and addition of 0.25; 0.50; 0.75 and 1.0% calcium anacardate (CA), respectively. The data were submitted to analysis of variance and treatment means compared with a SNK test (5%). The data from treatments containing CA were submitted to regression analysis. Treatments did not influence feed intake, egg production, egg weight, egg volume, feed conversion ratio and eggs quality parameters. The addition up to 1% of calcium anacardate in laying Japanese quail diet, does not influence their performance and egg quality.

Abstract The article reviews the metallurgical processes used in the first industrial ironworks operated in Brazil, the Patriótica Iron Factory, from 1812 to 1831. It discusses its impact on the ironmaking plants that spread in Minas Gerais's state during the XIX century. The remnants of this Factory in Ouro Preto were the first industrial site listed by the Brazilian Historic Heritage Authority (SPHAN) in 1938. Vale SA, owner of the site, and the National Historic and Artistic Heritage Institute (IPHAN) authorised collecting samples from two ferrous artefacts found in the old Factory, a hammer and an eyebolt nailed to the remnants of one of the reduction furnaces. The eyebolt’s microstructure suggests that this part was produced in the Patriótica Iron Factory, while the hammer’s microstructure indicates that this component was not produced in the Patriótica Iron Factory.

Resumen La hoja del jaborandi (Pilocarpus microphyllus) es la parte de la planta de interés económico de la cual se extrae la pilocarpina, por lo que la producción de hojas es la principal variable que determina la productividad de esa especie. La producción de hojas del Pilocarpus puede ser manejada por medio de la poda de sus ramas durante su fase de desarrollo. Con base en esto, el objetivo del trabajo es evaluar la regeneración de ramas de jaborandi sometidas a dos tipos de cortes y bajo sistemas de cultivos diferentes. En este experimento se realizaron podas en plantas de jaborandi, provenientes de diferentes accesos del Banco Activo de Germoplasma (Bag) de jaborandi, que estaban bajo diferentes sistemas de cultivos, a pleno sol y sombra. Con el auxilio de tijera de poda, se realizaron cortes a la altura de 10 y 20 cm de distancia de las bifurcaciones de las ramas en plantas de jaborandi. Los resultados mostraron que independiente de las distancias de los cortes realizados, las podas beneficiaron el surgimiento de nuevas brotaciones, logrando anticipar la cosecha e influir en la producción de hojas sin perjudicar el desarrollo de la planta. La poda drástica realizada en la especie Pilocarpus microphyllus estimula una regeneración eficiente sin dañar la planta proporcionando mayor producción de hojas independiente de la dirección de la poda realizada en el arbusto. Se observa que el cultivo del jaborandi se vuelve más productivo cuando se cultiva a pleno sol independiente del germoplasma utilizado y la cosecha de las hojas puede ser realizada durante todos los meses del año.

Abstract The leaf of the jaborandi (Pilocarpus microphyllus) is the part of the plant of economic interest, from which the pilocarpine is extracted, therefore, leaf production is the main variable that determines the productivity of this species. Pilocarpus leaf production can be managed during its development phase. Thus, the objective of the present study was to evaluate branch regeneration of jaborandi submitted to two types of cutting/pruning and different cropping systems. Prunings were carried out in jaborandi plants from different accessions from the Janorandi Active Germoplasm Bank (BGA), that were under different cropping systems, full sun and shade. With pruning shears, cuts were made 10 and 20 cm from the branch bifurcations. The results showed that regardless of the distances of the cuts in the jaborandi plants, the prunings benefited new shoots production and the harvest and influence on leaf production could be anticipated without harming the plant's development. The drastic pruning performed on the species also stimulated efficient regeneration without damaging the plant, resulting in bigger leaf production, regardless of the pruning direction. It was also observed that jaborandi cultivation becomes more productive when it is grown under full sun regardless of the germplasm used, and the leaves can be harvested in all the months of the year.

Abstract The continuity of an electrical system's services is linked to its equipment's correct operation. The more correctly they worked, the higher the quality of the services provided. Thus, they must have their functioning scanned closely and that minor defects have their evolution monitored. This fact creates the possibility of making predictions about how long equipment can operate without compromising the system's continuity. This follow-up is proper for predictive maintenance. This paper presents three on-going COPEL Generation and Transmission projects in essential elements of its electrical system: circuit breakers, lightning arresters, and SF6 substation. The central idea of all monitoring projects is to check the early problem in this equipment and facilities.
