The Rio da Batateira e Santana formations, the latter with Crato, Ipubi and Romualdo members (Alagoas Stage, Aptian), were studied in four cored and logged wells from the eastern portion of Araripe Basin, Northeastern Brazil. The investigated section is 230 m-thick, and PS-14 well is the most representative, because it is the only one which sampled the evaporites of Ipubi Member. Nine facies cycles were identified, being formed by siliciclastics (estuarine, deltaic and lacustrine), mixed lithologies (lacustrine), carbonates, black shales and marls (lacustrine), and gypsum-anhydrite (lacustrine evaporite). The ordering of facies cycles furnished six depositional sequences. They were formed by siliciclastic, regressive-transgressive R-T cycles (S1 and S4, corresponding to Rio da Batateira Formation and to Santana Formation/Romualdo Member), by siliciclastics and carbonates, R-T cycles (S2, S3.1 and S3.2, corresponding to Crato Member), and by siliciclastic-carbonate, R-T cycles followed by evaporitic cycles (S3.3, referred to Ipubi Member). The last cycles correspond to concentration-dilution, C-D cycles of marine brines, which precipitated gypsum in the restricted lacustrine basin.

The Aptian Barbalha Formation represents the first unit of the post-rift sequence of the Araripe Basin and crops out at the slopes of the Aranpe plateau in the eastern part ot Aranpe Basin. The unit has also been named Kio da Batateira Formation, but this name is here used in its original definition as Batateira Beds, an interval of great lateral continuity and characterized by the presence of bituminous shales of the Alagoas Stage (P-270 palynological biozone). This paper presents the results of a stratigraphic analysis carried out along the outcrop belt in order to establish the facies architecture and to interpret deposicional environments of the siliciclastic Barbalha Formation. Detailed stratigraphic vertical sections were measured and correlated. They allowed the recognition of two depositional sequences characterized by fining upward arrangement of facies, beginning with fluvial deposits and ending with lacustrine deposits at their tops. The end of the first cycle is represented by black shales and brecciated limestones of the Batateira Beds that record a geologic event of regional magnitude and serve as meaningful long-distance stratigraphic mark. The second deposicional sequence overlies disconformably the Batateira Beds and begins with clast-supported conglomerates, which are covered by a succession of fluvial sandstones and minor intervals of pelitic rocks. The sandstone content diminishes towards the top and the upper part of the unit is characterized by the presence of ostracode-rich green shales. The Barbalha Formation is conformably overlaid by Late Aptian lacustrine limestones belonging to the Crato Member of the Santana Formation.

The quality of life of caregivers is a concern because it directly affects the quality of life of individuals dependent on such care. This study aimed to analyze and compare the quality of life in health of caregivers of people with special needs who attend a rehabilitation facility. Ninety caregivers of people with special needs who attend a rehabilitation facility participated in this study. For data collection two instruments were used: a questionnaire to determine the profile of the caregiver and the person with special needs and the WHOQOL-Bref questionnaire to measure quality of life. The results were significant only between the caregiver's quality of life in the physical domain and age of the person with special needs, indicating that the older a person with special needs, the more difficult and arduous is the act of caring. The result can indicate guidelines for caring for families of people with disabilities.

O consumo de águas salinas pelas plantas na maioria dos casos afetam o rendimento das culturas em suas diversas fases prejudicando desenvolvimento e produção. O trabalho avaliou o consumo hídrico da rúcula (Eruca sativa) em sistema hidropônico NFT com águas salinas. Foram analisados seis níveis crescentes de salinidade da água (CEa), quais sejam: 0,2; 1,2; 2,2; 3,2; 4,2 e 5,2 (dS m-1) utilizaram-se duas fontes de sais: águas salobras (AS) e NaCl. Foi determinado o volume evapotranspirado por planta (VETc) no sistema durante o cultivo. O consumo hídrico nos primeiros dias após transplantio foi de 250 mL dia-1 aproximadamente para ambas as testemunhas e decresceram com o aumento da salinidade, a eficiência de utilização da água foi reduzida revelando uma resposta linear decrescente em função da salinidade ocorrendo uma resposta negativa das plantas que apresentaram uma redução na quantidade de folhas de 3,34%.
