For the economic exploitation of animal production in pastureland, it is essential to understand the morphophysiological responses of plants and animals to environment and management conditions, so that production can be efficient. This recommendation becomes more important in intensive pasture systems. In Brazil, especially in the Southeast, Midwest, North and Northeast regions, there is a predominance of tropical forage species, characterized by high dry matter production. However, problems su

The assets of a company have unquestionable value. Thus, their effective management is necessary. This management has been automated, i.e. the agent registers the assets with software and can report on it. However, the movements of goods from one place to another is unavoidable, and thus agents can lose their new location if they are not warned about the displacement. Thus, it is periodically necessary to make a complete survey of the property and then update the database. This project aims to b

This project aimed to contribute to the understanding of the interference of synthesis parameters on the properties of the nanomaterials obtained, allowing the integration of new variables into the photocatalyst project. The bench-scale testing of photocatalytic efficiency was performed using ultraviolet and visible radiation, observing the degradation of the dye and pesticide molecules through spectroscopic measurements in the UV-Vis range, electrochemical measurements, and measuring the genera

raditional breeding has generated significant genetic gain over time. However, this strategy falls short of yielding information on the biological processes involved. Additionally, there are great difficulties for the genetic improvement of characteristics which are measured solely in one gender and/or late in the life span of the animal. With the development of DNA chips it became possible maximizing genetic gain by reducing the generation interval and increasing the intensity of selection. The

One of the main post-harvest problems is the emergence of spoilage in oranges caused especially by fungi that depreciate the quality and decrease shelf life and may also compromise food safety. Various treatment technologies such as: modified atmosphere, irradiation, anti-microbial ice and high pressure, among others, have been studied in the quest to eliminate food pathogens. Thus, understanding mechanisms of microorganism control in foods have been the topic of intense research with the use of

Grassland intensification strategies such as fertilization and irrigation can be used to shorten the period required for recovery of paddocks under rotational management and thus to increase the productivity. In rotational stocking grazing, the definition of the resting and grazing periods of the paddocks, besides determining the total number of paddocks, exerts a great influence on the quantity and quality of the forage produced. The post-grazing residue, determined by the grazing period and th

Velloziaceae are an angiosperm family that contains the most desiccation-tolerant species (approximately 200 out of 270 species). These species are distributed among five genera: Acanthochlamys, Xerophyta, Barbacenia, Barbaceniopsis and Vellozia. More than 80% of theVelloziaceae species occur in South America, where the greatest morphological diversity is also found. The genus Vellozia comprises both desiccation-tolerant and non-desiccation-tolerant species, offering an excellent model for study

The main objective of this project was to develop an efficient methodology for the super-early resynchronization of non-pregnant females after Fixed-Time Artificial Insemination (FTAI) in dairy cattle. Super-early resynchronization strategies were studied using estradiol and progesterone (P4) on the 12th day after FTAI procedure, with or without the addition of non-steroidal anti-inflammatory drugs (NSAIDs), diagnosis of early pregnancy with Doppler on the 20th day based on blood flow in the cor

The presence of trees causes the interception of part of solar radiation in agricultural systems, mainly affecting shaded plants and variables such as energy balance, winds and water use by plants (Brenner, 1996). In addition to the restriction of solar radiation, there is also competition for water and nutrients near the row of trees (Magalhães et al., 2018). Thus, controlling competition for light among forest species and reducing tree drain strength for agricultural and forage crops can repre ...

Umbu (Spondias tuberosa) and wild passion fruit (Passiflora cincinnata) are native fruits that stand out in the Caatinga biome. These species are consumed as part of dietary habits of the population from the Brazilian Semiarid at the same time that some of them are in endangered risk due to ongoing deforestation and environmental imbalance. Agroindustrialization is an alternative to add value to agricultural production and to complement crops management actions. This project aim
