Different approaches and effectiveness in orthodontic traction of impacted cani...

Canines have a fundamental role in the dental arch, both aesthetically and functionally. Apart from the third molars, maxillary canines are the most frequently impacted teeth. Orthodontic traction of an impacted canine is one of the most appropriate approaches when there is a good prognosis, in growing patients and without a serious lack of space in the arch. This systematic review aims to describe the differen...

Takotsubo Syndrome Associated with Thyrotoxicosis: A Clinical Case

Takotsubo syndrome or stress-induced myocardiopathy is responsible for a significant number of cases with suspected acute coronary syndrome characterized by transient left ventricular ballooning often precipitated by psychologically or emotionally stressful events. Its occurrence associated with thyrotoxicosis in the context of Graves' disease is described as most likely caused by the exacerbation of catecholam...

Hybridizing construction: the transformative influence of Ceramic Am

In recent years, there has been a notable increase in research exploring the application of additive manufacturing (AM) technologies to produce architectural components, opening a realm of new possibilities. This heightened interest has spurred the emergence of novel fields of research, the introduction of new materials, and the exploration of innovative applications for existing ones. The utilization of digita...

Water infrastructure asset management: A contribution to reducing disruptions i...

This chapter covers some key topics for asset management in general and for the administration of water supply and wastewater treatment infrastructure in particular. These infrastructures are public goods with high economic investment and are essential for the provision of basic services to the population and must therefore be managed in a sustainable manner to guarantee a high-quality service in harmony with e...

The UTE-PLANAGEO Project (National Geology Plan of Angola). Objectives, methods...

ABSTRACT: The National Geology Plan of Angola (PLANAGEO) has been one of the most important Angolan infrastructure projects throughout the past twenty years. The objectives of PLANAGEO were: (a) to enhance Angola's geological and mineral resources knowledge; (b) to foster diversification of the national economy; and, (c) to attract foreign investment and promote the country development. The project integrated r...

Soil Classification Maps for the Lower Tagus Valley Area, Portugal, Using Seism...

ABSTRACT: The Lower Tagus Valley (LTV) region has the highest population density in Portugal, with over 3.7 million people living in the region. It has been struck in the past by several historical earthquakes, which caused significant economic and human losses. For a proper seismic hazard evaluation, the area needs detailed V-s30 and soil classification maps. Previously available maps are based on proxies, or ...

Detailed in-depth mapping of the world largest anorthositic complex: Magnetic a...

ABSTRACT: The Kunene Complex (KC) represents a very large Mesoproterozoic igneous body, mainly composed of anorthosites and gabbroic rocks that extends from SW Angola to NW Namibia (outcropping 18,000 km2 , NE-SW trend, and ca. 350 km long and up to 50 km wide). Little is known about its structure at depth. Here, we use recently acquired aerogeophysical data to accurately determine its hidden extent and to unra...

Reappraisal of active tectonics of the Porto Alto buried fault zone (Portugal) ...

ABSTRACT: The Lower Tagus Valley area (LTV), where Lisbon is located, has been affected by several destructive, M 6+ earthquakes whose sources remain to be determined. The identification of expectable surface or near surface ruptures in the area is a challenging task that requires a multidisciplinary analysis that includes geophysical techniques, as the source faults are mainly buried despite likely to deform U...

SedDARE-IB: an open-access repository of sediment data for the Iberian Peninsul...

ABSTRACT: Sediments provide valuable information for geologists and geophysicists whenever they strive to understand, and reproduce, the geological evolution, lithology, rock properties, seismic response, and geohazards of a region. The analysis of sedimentary sequences is thus useful for the interpretation of depositional environments, sea-level change, climate change, and recognition of the sediments' source ...
