Northern Potwar Deformed Zone (NPDZ) is a part of the foreland zone of NW Himalayan folds and thrust belt. Seismicity map has been prepared for this region, which appears to be less active as compared with adjacent re-gions with apparently no distinct pattern or relationship with surface structures. Focal mechanism solutions of 4 events, for which required parameters are available, indicate left-lateral strike- slip faulting for 3 events and thrust-ing for one event. P-axes orientations are in NW-SE and NE-SW. Basement is most likely involved in the ongoing deformation.

On October 8, 2005, an earthquake of Mw 7.6 shook northern Pakistan at 8：50：38 AM local time. The epicenter was located at 34°29′35″N, 73°37′44″E （USGS）, in Neelum Valley, 19 km northeast of Muzaffarabad, the capital town of Pakistan-administered Kashmir. This deadliest of the Himalayan earthquakes took a toll of more than 80,000 of human lives, rendered millions homeless, and caused an estimated damage of US $ 5 billion.

Climate change, mainly caused by the use of non-renewable fuels, has raised global concerns and led to the search for less polluting energy sources, making hydrogen a promising energy alternative with the potential to contribute to changes in the energy mix of various countries through the use of technologies that enable its production and use with low or zero carbon emissions. In this context, Brazil has aroused great interest from other countries in exploring its renewable resources for the production of hydrogen (green hydrogen). In this sense, the use of natural gas pipelines and the use of hydrogen in mixtures with natural gas have become the subject of studies due to their economically viable alternative for the immediate use of this energy vector. However, there are still technical and regulatory challenges regarding the integration of hydrogen into the existing natural gas pipeline network. In this context, the present study aims to address the effects of hydrogen interaction with the structure of natural gas pipeline steel and the regulatory barriers to the use of this network for the transportation of green hydrogen, particularly in the state of Ceará/Brazil. After extensive analysis of literature and regulatory documents, it was concluded that: 1) Ceará/Brazil has strong potential to meet the demand for green hydrogen through the use of solar and wind energy sources;2) there is feasibility for the adaptation or conversion of natural gas infrastructure for the transportation of green hydrogen;3) discussions regarding the regulatory competence of green hydrogen transportation and distribution through the natural gas network in Brazil are still incipient;4) the current regulation of the natural gas industry can serve as a subsidy for the regulation of green hydrogen and natural gas transportation.

The accelerated growth of the vehicular fleet, the modernization of large urban centers, and the few adjustments to the road network in Fortaleza have intensified the problems of traffic and emissions of atmospheric pollutants, highlighting the necessity for strategic urban planning initiatives to address the escalating issues of traffic and pollution. With the objective of analyzing the indices of concentrations of atmospheric pollutants and estimating how these levels can affect human health, this work consists of a study of the analysis of air quality in the intense trade region of Fortaleza. For this, the analysis zone was divided into three perimeters (Major - Medium - Minor), where each perimeter was analyzed at 7 am, 12 noon and 5 pm. Concentrations of the type of O3, particulate matter (PM2.5 and PM10), CO2 and HCHO were collected. Our results demonstrate that most of the analyses are within the limits of current legislation;however, at certain times and perimeters, the analyses of CO2 and HCHO exceeded the established limits. In view of the above, we conclude that public policies to control air quality are necessary to reduce the damage to human health and the environment caused by pollutants.

This study aimed to describe structure, functionality and development of pediatric heart transplant families, from the understanding of the experienced chronic condition. A descriptive, exploratory study using a qualitative approach was developed in a hospital situated in a city of Northeast Brazil, in 2012. The study was conducted with three families, using the Calgary Family Assessment Model (CFAM). In addition to the genogram, an analysis of the children’s/adolescents’ family members was conducted at the time of interview. Two families were binuclear families and one was mononuclear. From the evaluation, it was possible to determine the care and support network of children and adolescents with heart transplants, as well as some difficulties faced by the investigated families. Nurses are important in this family context since the visualization of the family genogram can generate a change in the nursing care to each family.
