Abstract
Brazil is a country of continental dimensions, with a surface area of 8,510,296km2 , which is distributed among 26 federal states and a federal district. However, due to an extremely unequal income distribution, one of the major social problems that the country still faces is urban segregation, experienced by a large part of its almost 212 million inhabitants, who still find severe problems with housing, public transportation, security, health, employment, education and infrastructure, especially with regard tothe process of collecting and the treatment of waste generated. In the case of solid urban waste (SUW), approximately 190,000tons are produced daily, which implies a per capita production rate of 0.90kg(inhab.day)-1. Of the total generated, a fraction greater than 90% (w/w) is collected and, of this fraction, a percentage of 25% is still disposed of in open dumps, generating environmental impacts of different magnitudes. In addition, of the quantity of SUW generated in Brazil, about 55% (w/w) corresponds to putrescible organic matter, which could be fully used as an alternative source of energy (methane gas, for example), which normally does not occur. In these terms, Brazil becomes a country with strong social, economic and public health problems, and with regard to basic sanitation, there are still great demands, especially when considering the collection and treatment of the various types of waste generated.
Keywords: Poverty, Sanitation, Environment, Public cleaning, Environmental sustainability.

 Resilience, Risk-Taking Behavior and Aggression among Female Volleyball Players – a Preliminary Study The aim of the current study is to investigate the level of risk-taking behavior, resilience and aggression in female volleyball players and the link between these psychological variables and coach’s performance ranking. A Romanian volleyball team ranked 7th out of 11 in the A1 league in the national championship (2022-2023 period) participated at the study. The Romanian adaptation of the Brief Resilience Scale, The Romanian adaptation of Makarowski’s Stimulating and Instrumental Risk Questionnaire, The Romanian adaptation of Makarowski's Aggression Questionnaire and Delphi method (evaluation of female volleyball players by coaches) were used. Analysis of the results reveals that athletes have a low level of perseverance (Go-Ahead factor), a low level of Foul play and a moderate to low level of assertiveness. Also, most athletes registered average or even low levels of resilience

 Chemo stratigraphic Profile of a Reservoir in Well “X” of Field “Y” Offshore Southern Gabon - Stephy Publishers In a bid to evaluate the elemental and mineralogical content of reservoir samples from the “X” well in the “Y” oil field offshore Southern Gabon, analyses were performed using XRD and XRF. The log view profile of the result inferred that Na, Mg, and Calcite were absent in the shallower series of the reservoir sandstones studied, this observation implies that they are soluble ions that had eroded and refer to warm and humid paleoclimate and a depositional environment that is arid, which corresponds to the continental crust as their source. The plot of Ti and FeO+Mg discriminate the deeper series of the reservoir sandstone samples from the shallower samples. The lower series showed heavier values which implies their origin from Oceanic Crust. These are also the pre-salt facies while the shallower series were more of continental origin and represent the post-salt facies. https:
