Sedimentary reservoirs describe facies that characterise architectural segments of the basin. For example, channels and alluvial fans are the main silicoclastic depositional environments. Thus to some extent these sites have hydrocarbon potential. The analysis of the hydrodynamic mechanisms behind their emplacement and their potential was carried out using oil drill cores. They were exhumed between 6500 and 10000 feet, i.e. between 1981 and 3048 m deep in the Abidjan Margin, Gulf of Guinea province in Côte d'Ivoire. The facies is based on lithological, ichnological and mechanical criteria.

One learning model that fits the conceptual change approach is the dual situated learning model, which benefits students due to its integration of three philosophical perspectives: epistemological, ontological, and motivational. This study aims to determine the impact of dual situated learning on secondary school students' performance in chemistry. A quasi-experimental approach was used, with a pretest-posttest non-equivalent group design. The study sample included 60 secondary school students from the Kannur area.

Introduction: Thyroid abscess is a rarely encountered clinical entity since thyroid gland is generallythought to be resistant to most infections. Fine Needle Aspiration Cytology (FNAC) can bean iatrogenic route for infection. Case report: A 47 year old immunocompetent female with large multinodular goiter since 20 years who developed sudden increase in swelling size associated with pain and swallowing difficulty. History revealed that acute symptoms started after FNAC. This case report emphasizes on the fact of adopting aseptic precautions even for minimally invasive procedures.

A Síndrome da Imunodeficiência Adquirida. (SIDA), trata-se do resultou da infecção do vírus denominado HIV (Vírus da Imunodeficiência Humana), sendo caracterizado por ser um retrovírus, com genoma RNA (ácido ribonucleico), da família Retroviridae e subfamília Lentiviridae. Com o cenário de infecção em mulheres entre 20 a 34 anos, sendo estas em idades férteis, tornou-se preocupante a ocasião do aumento da transmissão vertical entre mãe e Recém-Nascido (RN).

Introduction: Chronic Kidney Disease (CKD) is considered a public health problem, characterized by the presence of kidney damage or a reduced level of kidney function (glomerular, tubular and endocrine), with progressive and irreversible loss. Objective: to identify in the literature the strategies carried out by the multidisciplinary team for the early diagnosis and treatment of CKD in the context of Primary Health Care. Method: This is an integrative literature review.

In the case of rapidly emerging viral pandemics such as the novel coronavirus, rapid development and large-scale implementation of vaccines is a critical need that may not be met by the use of conventional technologies alone. Nanostructured materials have proved to be great allies in vaccine design, catalysing their construction and allowing clinical trials to begin at an unprecedented speed. Among the main immunisation techniques benefited by nanoscience, we can highlight RNA vaccines.

It is increasingly common to perform surgical procedures in dentistry offices. Furthermore, the number of patients who need to undergo these procedures and use oral anticoagulants or antiplatelet agents has also been increasing. Oral anticoagulants are drugs whose main function is to increase blood clotting time, and have been widely prescribed as prophylaxis to avoid thromboembolic phenomena. It is essential that the professional dentist should be duly qualified to know which protocols should be followed when performing operative techniques in these patients.

O excesso de tecido adiposo pode ser considerado uma condição indesejada, inadequada e divergente do padrão socialmente estabelecido, onde é enaltecido o corpo magro e desqualifica o corpo da pessoa com obesidade. Estatisticamente, o Brasil ocupa o terceiro lugar entre os homens no ranking mundial da obesidade e o quinto lugar entre as mulheres. Entretanto, na categoria de obesidade severa, o país está localizado no quinto lugar entre os homens e o quarto lugar entre as mulheres.
