Apart from the initial similarities in the clinical presentation, there are further similarities between such as risk factors for development of severe illness, cytokine storms, endothelial dysfunction and multi-organ failure. However, while dengue is usually associated with a tendency to bleed, development of micro and macrothrombi is a hallmark of severe COVID-19.

Here we discuss the similarities and differences between the two infections so that lessons learnt so far from studying both infections will be helpful in further understanding their immunopathogenesis and to develop therapeutic interventions.Īlthough the entry routes of the SARS-CoV-2 and the dengue virus (DENV) are different, both infections result in a systemic infection, with some similar clinical presentations such as fever, headache, myalgia and gastrointestinal symptoms. Many countries in Asia and Latin America are currently facing a double burden of outbreaks due to dengue and COVID-19. This work has been conducted in collaboration with the managers of the coal yard of a power plant. A prototype has been built from inexpensive components to demonstrate the effectiveness at detecting and extinguishing arising fires, and a solution has been costed for the coal yard in the case study. The heat direction algorithm calculates the parameters to position the water dispenser so that it covers the area. Each tower includes an inexpensive infrared detector, a water dispenser and a controller programmed to identify areas of elevated temperature, and actuate the dispenser. In this study, we propose to build a complete firefighting solution which is mounted on a number of towers sufficient to cover the area of an open coal yard, complete with redundancy. Most often, human intervention is necessary, which is both slow and dangerous for the firefighters involved. A plethora of studies have modelled this oxidation behavior and proposed countermeasures.

Depending on the environment-temperature, ventilation, and the rank of the coal-heating and self-ignition can be a longer or shorter process, but the possibility can never be entirely dismissed. Coal yards are prone to spontaneous ignition, a problem faced in every country that stores or transports coal.

In spite of recent moves to wean the world of fossil fuels, coal remains the main source of power in many countries. Therefore, this chapter represents the algal functional compounds and their health benefits that can be used as candidates in the food and nutraceuticals industry to improve human health. Also, they are rich in bioactive metabolites of polyphenols, alkaloids, tannins, flavonoids, sterols, enzymes, essential fatty acids, peptides, pigments, and are reported to exhibit human beneficial effects. Edible macroalgae are rich in carbohydrates, protein, soluble dietary fiber, and a range of vitamins and minerals. Globally, the demand for edible seaweeds has increased due to high nutritional value and is increasingly being consumed by Asians due to the functional benefits beyond the traditional considerations of nutrition and health. Marine algae have a long history of use in functional foods and nutraceuticals due to the presence of valuable sources of bioactive compounds and they are considered “superfoods” in the food industry. Hence, there has been a growing interest in natural resources that can be used in functional food, nutraceuticals, and pharmaceutical products. Lifestyle changes associated with the consumption of healthy foods and nutraceuticals should play a significant role in preventing and managing chronic diseases. The modern lifestyle and dietary habits increased the progression of non-communicable diseases both in developed and developing countries.
