Cassava (Manihot esculenta Crantz) is a highly consumed root and a significant source of carbohydrates in Brazil and around the world. In the state of Pará, cassava is vital to the local economy, especially in the municipality of Tracuateua. The culture involves family farmers and serves as an important source of income and subsistence. Different cultivars are used, such as BRS Tapioqueira and BRS Verdinha, which exceed 70 thousand kg/ha with good management. Adequate fertilization, pest control and weed management are essential for high productivity. Irrigation can significantly increase production. On the property of Mr. Benedito Dutra, member of the RENIVA project, the production of seed cassava and cowpea is highlighted. It uses cultivars developed by Embrapa, such as BRS Kiriris, BRS Formosa and BRS Novo Horizonte, which are recommended for industrial use. Dutra also grows cowpeas, using varieties such as BRS Guirá and BRS Natalina, which are highly productive and adapted to local conditions. The property has an irrigated area of 23 hectares per central pivot, ensuring crop hydration during dry periods. During the field visit, several areas of experimentation were observed. The experimental plots of cassava and cowpea showed good performance, with a high survival rate and resistance to pests. The integration of advanced soil management, pest control and irrigation practices highlighted the property as an example of innovative agriculture. The experience on Mr. Dutra’s property demonstrated the importance of innovation and adoption of advanced agricultural practices for sustainable and productive agricultural production.

ANTIMICROBIAL POTENTIAL OF COCONUT OIL IN BACTERIA CULTURED FROM THE ORAL ENVIRONMENT

2024-11-07T20:36:54-03:00

The study addressed the antimicrobial potential of coconut oil, both extra virgin and homemade, against oral bacteria. For this evaluation, chlorhexidine was used as a comparison standard. The tests were conducted in five culture media, one for chlorhexidine, another for extra virgin coconut oil, and a third for homemade coconut oil. The results revealed that extra virgin coconut oil exhibited partial inhibition of bacterial growth, being effective only against certain strains, while homemade coconut oil showed no considerable effectiveness in any test. On the other hand, chlorhexidine displayed the expected and excellent antimicrobial action. These results highlight the need for further studies on extra virgin coconut oil, especially to better understand the bacteria it inhibits, in order to promote a more effective use of this compound.

ENVIRONMENTAL ASSESSMENT OF THE AREIA BRANCA ECOTOURIST PARK (TRÊS FRONTEIRAS, SÃO PAULO)

2024-11-30T15:43:04-03:00

Parks are considered important for promoting sustainable development in cities and for offering ecosystem services. The environmental quality in the Parks and their anthropic occupation is a topic that must compose the public administration’s agenda. The present dissertation analyzed the occupation of the Ecotouristic Park of Areia Branca (Três Fronteiras, State of São Paulo) and its environmental risks, making a historical-legal and environmental survey of the area, in addition to subsidiarily helping in the formulation of public policies for the place. The Areia Branca Ecotouristic Park is of fundamental importance for the preservation of ecosystem services in the region, as in addition to serving as a cradle and development of animals and plants, they also protect the soil from erosion by rainwater in the headwaters, in addition to contributing to with aquifer recharge. The Park area consists of a green belt of medium and large vegetation, extending beyond the park over an extensive area. In this way, it protects rivers and streams from the action of pesticides from crops present in the area, in addition to being used for leisure, sports and to contain fishing areas. This research aims to analyze the services of the ecosystems present in the Park and raise risk situations for the environmental quality of its surroundings. The diagnosis of the area was carried out through a survey of ecosystem services (provision, regulators, support and cultural services) in the study area and its surroundings, through direct observations of the location, verifying possible agents causing changes. The environmental assessments of the indicated ecosystem services will serve to support public managers and environmental agents so that they can adopt protective measures aiming at a local environmental conservation policy, with a view to the sustainable development of the area. In the Park area, the presence of regulatory, support, provision and cultural services was verified, whose classification was proposed by the “Millennium Ecosystem Assessment”, based on the functionality of ecosystem services. The results obtained point to the existence of several services in the Park that contribute directly and indirectly to human well-being with relevant benefits for society, in terms of maintenance, recovery or improvement of local and regional environmental conditions.

The objective of this work is to measure the signal strength of mobile telephony to verify the signal quality of two mobile operators in the urban area of the municipality of Santa Helena / PR. Signal strength data is obtained through a smartphone application, measured at different points in the municipality. The results obtained according to the statistical calculations performed show that for X operator the signal quality is between good and excellent, for Y, the signal quality is between regular and poor.

INSPECTION AND MAINTENANCE OF LAND DAMS

2024-12-24T11:58:24-03:00

Periodic inspection of dams is vital to ensure safety and minimize environmental and social risks. This study focused on the inspection techniques for earth dams at the Residencial Condominio Area in Goiânia, Goiás, addressing methods such as visual inspection, as well as advanced technologies. Significant issues were identified in dams 01 and 02, including excessive vegetation, coastal erosion, sedimentation, and deterioration of the impermeable membrane, which affect stability and water quality. The study recommends corrective actions such as tree pruning, vegetation control, and repairs to the impermeable membrane, emphasizing the importance of regular maintenance to protect communities and the environment. Another point of observation found in this work is the precariousness of safety and protection barriers for people and animals that live in their neighborhoods.

A NEW APPROACH TO CALCULATING THE DIFFERENCE BETWEEN TWO NATURAL NUMBERS

2024-12-31T16:31:43-03:00

This paper aims to present a way to calculate the difference between two natural numbers in which the digits of the minuend are almost or all smaller than the digits of the subtrahend, without using the archaic expression “x to y”, as in the example 23 - 19 where we say “nine to thirteen is four, go one”, which the student has great difficulty understanding. Therefore, this text contributes positively to the teaching-learning process of the aforementioned content.
