Wood Ash Based Treatment of Anaerobic Digestate
The anaerobic digestion (AD) was first applied to deal with the sewage sludge (SS) produced during the primary and secondary treatment of wastewater, but its use to deal with agro-waste and the MSW with around 70% of organic material has been subsequently encouraged.

Water Extraction from the Atmosphere for Arid Zones
The air may be used as a sustainable water supply because it contains over 14,000 km3 of water vapor. There are two methods for extracting water from ambient air. The first approach entails lowering the temperature of humid ambient air to below the dew point. The second method entails sucking water vapor from moist ambient air with a solid adsorbent and a liquid absorbent and then retrieving the water by heating the absorbent and liquefying the evaporated water. Dew water appears to be an easy way to supplement drinking water supplies in a few parts of the world. Small animals and plants are the primary consumers of dew water, as it is necessary for maintaining their activities in a semiarid or dry environment.

Vulnerabilities and Potential Threats of Cloud computing
Cloud computing has become a prominent technology due to its important utility service; this service concentrates on outsourcing data to organizations and individual consumers. Cloud computing has considerably changed the manner in which individuals or organizations store, retrieve, and organize their personal information. Despite the manifest development in cloud computing, there are still some concerns regarding the level of security and issues related to adopting cloud computing that prevent users from fully trusting this useful technology.

UV-A Photocatalysis in Livestock and Poultry Farming
As the scale of the livestock industry has grown with the increase in the demand for livestock and poultry products, gaseous emissions, an unwanted side effect of livestock and poultry production, are also increasing. Various mitigation technologies have been developed to reduce such air pollution, and the mitigation technologies are divided mainly into “source-based type” (meant to fundamentally reduce the emissions) and “end-of-pipe type” (physicochemical and biological treatment of the output from barns to reduce the release into the environment). Ultraviolet light (UV) can be considered as both end-of-pipe (treating exhaust air from barns) and source-based type (treating air inside the barn).

Using Product Design Strategies to Implement Circular Economy
The design strategies referred to industrial design, e.g., user-centered design and timeless design were preferred by professional designers. The design strategies related to routine design, i.e., materials substitution, reducing resources and energy consumption, and structural optimization, were indistinctly used by both students and professional designers.

Urban Greenery as a Complex System
A complex system is an open system in a state of dynamic equilibrium. It can also be described as a network connecting the various elements that constitute the system itself. The Urban Green System (UGS) is one such complex system. In this regard, its first characteristic is that it can be described as a network of green elements (areas, linear infrastructures, points) with variable rules governing the connections linked to their main functions in the urban context. Furthermore, it is an open system that exhibits dynamic relationships with all of the other components of the city.

Unmanned Aerial Vehicles in Precision Agriculture Sensing Applications
Precision agriculture (PA) is becoming highly significant in today’s technologically advanced world and has been considered as the farm for the future. This is a modern farming management concept using digital techniques to monitor and optimize agricultural production processes by using technological advancement. PA uses modern technology and principles to manage the spatial and temporal variability in all aspects of agricultural production for the goal of improving crop performance.

Unmanned Aerial Vehicle Forest RS
Natural, semi-natural, and planted forests are a key asset worldwide, providing a broad range of positive externalities. For sustainable forest planning and management, remote sensing (RS) platforms are rapidly going mainstream. In a framework where scientific production is growing exponentially, a systematic analysis of unmanned aerial vehicle (UAV)-based forestry research papers is of paramount importance to understand trends, overlaps and gaps.
