Types of Pipeline Anomalies
Pipelines are considered the most efficient way to transport oil and gas resources. However, this advantage of pipelines may be lost if pipeline integrity is not ensured. Geometric deformations, metal losses, and crack-type anomalies caused by various reasons in the pipeline threaten the integrity of the pipeline. Therefore, it is important to examine the causes of occurrence, hazard potentials, and management methods of pipeline anomalies as part of pipeline integrity management.

California Current
The California Current is a Pacific Ocean current that moves southward along the western coast of North America, beginning off southern British Columbia and ending off southern Baja California Sur. It is considered an Eastern boundary current due to the influence of the North American coastline on its course. It is also one of five major coastal currents affiliated with strong upwelling zones, the others being the Humboldt Current, the Canary Current, the Benguela Current, and the Somali Current. The California Current is part of the North Pacific Gyre, a large swirling current that occupies the northern basin of the Pacific.

Lowland Irrigated Areas of Ethiopia
Ethiopia’s irrigated agriculture productivity has been threatened by severe salinity and sodicity problems which have resulted in significantly lower yields, food insecurity, and environmental degradation. The destructive effects of poor irrigation water management with the absence of drainage and anticipated future climate changes can accelerate the formation of salt-affected soil, potentially expanding the problem to currently unaffected regions.

Geographic Information Systems Within Enterprise Resource Planning Systems
Geographic information systems (GIS) have become very important tools in many areas in recent years, including resource management and utilization in many industries. GISs are sometimes referred to as computer tools, but sometimes they are defined as information systems consisting of software and database.

Rainfall Threshold
Sediment-related disaster is one of the most significant natural disasters, from the perspective of magnitude, damage and loss to human life and infrastructure, and disruption to socio-economic activities. The rainfall threshold is the condition or amount of rainfall that is likely to initiate sediment-related disasters, it is agreed that the rainfall threshold is the most significant tool to predict impending occurrences.

Education for Sustainable Development
Education can serve the purpose of trying to mitigate catastrophes, from the climate change education perspective. Therefore, understanding how teachers are engaging with sustainability issues can help to reveal how they cope with it. In a school context, teachers can have a role in enacting an interconnection between critical thinking (CT) as a potentially useful tool and education for sustainable development (ESD), in terms of educating and communicating the importance of sustainability to future generations.

Arsenic Induced Neurotoxicity
Arsenic is a ubiquitous environmental contaminant widely distributed in the surrounding environmental compartments. Exposure to inorganic arsenic is known to cause major neurological effects such as cytotoxicity, chromosomal aberration, damage to cellular DNA and genotoxicity. On the other hand, long-term exposure to arsenic may cause neurobehavioral effects in the juvenile stage, which may have detrimental effects in the later stages of life. Thus, it is important to understand the toxicology and underlying molecular mechanism of arsenic which will help to mitigate its detrimental effects.

Prognathodon
Prognathodon is an extinct genus of marine lizard belonging to the mosasaur family. It is classified as part of the Mosasaurinae subfamily, alongside genera like Mosasaurus and Clidastes. Prognathodon has been recovered from deposits ranging in age from the Campanian to the Maastrichtian in the Middle East, Europe, New Zealand, and North America. Prognathodon means "forejaw tooth", which originates from the Latin pro- ("earlier" or "prior"), Greek gnathos ("jaw") and odṓn ("tooth"). Twelve nominal species of Prognathodon are recognised, from North America, northern and western Africa, the Middle East, western Europe and New Zealand. Due to the sometimes clear differences between them and the incomplete nature of many of the specimens, the systematics of the genus and which species should properly be considered Prognathodon is controversial. Some species have been assigned to other genera, such as Dollosaurus and Brachysaurana, but this has also been questioned. Prognathodon is known for its massively built jaws and teeth. Its distinct feeding adaptations have generated much interest in its ecology ever since its discovery, though direct evidence of its diet, such as gastric residues, is rare.

Air Quality during Covid-19 Lockdown
Air pollution exposure is one of the greatest risks to health worldwide. It is estimated to be responsible for about 4.2 million deaths around the world every year owing to many serious diseases such as heart disease, stroke, acute and chronic respiratory diseases, and lung cancer. The WHO guideline limits are exceeded in several areas around the world, and it is estimated that about 90% of the world’s population is exposed to high air pollution levels, especially in low- and middle-income countries. The COVID-19 pandemic has forced governments to implement severe mobility restriction measures to limit the spread of the virus. This represented a unique opportunity to study the impact of mobility on urban air quality. Several studies which have investigated the relations between the quality of the air and such containment measures have shown the significant reduction of the main pollutants in the urban environment so to encourage the adoption of new approaches for the improvement of the quality of air in the cities. The aims of this entry are both a brief analysis and a discussion of the results presented in several papers to understand the relationships between COVID-19 containment measures and air quality in urban areas.

Hyperspectral Remote Sensing and Plant
Hyperspectral remote sensing provides image data with very high spectral resolution. This high resolution allows subtle differences in plant health to be recognized. Such a multidimensional data space, generated by hyperspectral sensors, has given rise to new approaches and methods for analyzing hyperspectral data.
