The mangrove is an ecosystem present along the entire coast around the world that serves as a
place of transition between terrestrial and marine environments. It is a typical environment of
tropical areas, possessing high biodiversity and of fundamental importance for ecological
balance, and can be considered one of the most important ecosystems on the planet. Having
valuable importance for the city of Macau/RN and for the population in a cultural, historical
and economic way, it also has great environmental value as it is a source of food and
reproduction of marine animals, and also for the fishing industries. But, despite being known
for having great wealth and biodiversity, it is in a very advanced state of degradation. With this
in mind, the present work aims to present a study on analysis, control and research of mangrove
waters in the city of Macau/RN, that is, to indicate and understand the problems relating to the
mangrove and its great degradation. The analyzes were carried out following the parameters:
temperature, pH, turbidity and electrical conductivity.

The present academic work aims to develop pineapple-based liquor and characterize its profile
through physical-chemical and sensorial analyses. It begins with bibliographical research,
carrying out a historical survey on the origin of alcoholic beverages and liquor, as well as the
production stages. Based on the information obtained, two pineapple liqueurs were produced,
using the fruit and peel, and physical-chemical analyses were carried out (pH, total solids, total
acidity, alcoholic content) and sensorial (taste, color, aroma). Thefore, given the analyzes
carried out and results obtained within the parameters established during the work, the
development of pineapple-based liqueurs shows good sensory acceptance for consumption.

The demand for oil continues to be very high, taking into account that world production is
estimated at around 89.8 million barrels produced daily, used for many purposes, including the
main one - energy -, it currently moves the global economy, generates profits and capital
increase for countries with this natural resource. Brazil is concentrated in its production in the
states of Rio de Janeiro and Rio Grande do Norte. The city of Macau located in Rio Grande do
Norte has approximately 78 oil wells in operation at the moment, currently with greater
exploration in mature wells previously used for extraction. Despite the economic prosperity
provided by oil and natural gas production, corrosion has been an obvious obstacle to obtaining
greater profits from the transport, storage and production of petroleum derivatives, as it
compromises structures and can lead to leaks with capital and environmental damage, in
addition to natural disasters. The objectives of this work are aimed at better understanding the
relationship between corrosion and damage caused to oil and gas pipelines, as well as to prove
the topics presented in the theoretical framework, based on the methodology of an online form
aimed at a professional working in the industry, who verified the veracity of the facts reported
by the scientific research in this article – commonly the incidence of corrosion induced by acid
gas attacks and BRS bacteria, presence of hydrogen sulfide, carbon dioxide and oxygen gas, a
difference evident in the constitution of ducts depending on the environment in which they are
inserted, and mapping with corrosion coupons mentioned prior to the application of the digital
form – concluding the success in directing the bibliographic review.
