Wire Arc Additive Manufacturing Process
Wire arc additive manufacturing (WAAM) is an emerging and promising technology for producing medium-to-large-scale metallic components/structures for different industries, i.e., aerospace, automotive, shipbuilding, etc. It is now a feasible alternative to traditional manufacturing processes due to its shorter lead time, low material waste, and cost effectiveness. WAAM has been widely used to produce components using different materials, including copper-based alloy wires, in the past decades.

Dragon Boat
A dragon boat is a human-powered watercraft originating from the Pearl River Delta region of China 's southern Guangdong Province. These were made of teak, but in other parts of China, different kinds of wood are used. It is one of a family of traditional paddled long boats found throughout Asia, Africa, the Pacific islands, and Puerto Rico. The sport of dragon boat racing has its roots in an ancient folk ritual of contending villagers, which dates back 2000 years throughout southern China, and even further to the original games of Olympia in Ancient Greece . Both dragon boat racing and the ancient Olympiad included aspects of religious observances and community celebrations, along with competitions. Dragon boat racing has been a traditional Chinese paddled watercraft activity for over 2000 years and began as a modern international sport in Hong Kong in 1976. These boats are typically made of carbon fiber, fiberglass, and other lightweight materials. For competition events, dragon boats are generally rigged with decorative Chinese dragon heads and tails. At other times (such as during training), decorative regalia is usually removed, although the drum often remains aboard for drummers to practice. For races, there are 18-20 people in a standard boat, and 8-10 in a small boat, not including the steersperson (helm) and the drummer. In December 2007, the central government of the People's Republic of China added the Dragon Boat Festival, along with the Qingming and Mid-Autumn festivals, to the schedule of national holidays.

Pre-clinical Cerebral Perfusion MRI Techniques
Alterations to the cerebral microcirculation have been recognized to play a crucial role in the development of neurodegenerative disorders. However, the exact role of the microvascular alterations in the pathophysiological mechanisms often remains poorly understood. The early detection of changes in microcirculation and cerebral blood flow (CBF) can be used to get a better understanding of underlying disease mechanisms. This could be an important step towards the development of new treatment approaches. Animal models allow for the study of the disease mechanism at several stages of development, before the onset of clinical symptoms, and the verification with invasive imaging techniques. Specifically, pre-clinical magnetic resonance imaging (MRI) is an important tool for the development and validation of MRI sequences under clinically relevant conditions. This article reviews MRI strategies providing indirect non-invasive measurements of microvascular changes in the rodent brain that can be used for early detection and characterization of neurodegenerative disorders. The perfusion MRI techniques: Dynamic Contrast Enhanced (DCE), Dynamic Susceptibility Contrast Enhanced (DSC) and Arterial Spin Labeling (ASL), will be discussed, followed by less established imaging strategies used to analyze the cerebral microcirculation: Intravoxel Incoherent Motion (IVIM), Vascular Space Occupancy (VASO), Steady-State Susceptibility Contrast (SSC), Vessel size imaging, SAGE-based DSC, Phase Contrast Flow (PC) Quantitative Susceptibility Mapping (QSM) and quantitative Blood-Oxygenation-Level-Dependent (qBOLD). We will emphasize the advantages and limitations of each strategy, in particular on applications for high-field MRI in the rodent’s brain.

Environmental Performance of FRP
FRPs (fiber-reinforced polymers) have gained increasing popularity in the last few years due to their durability, high corrosion resistance, light weight and high strength. Life cycle assessment is considered one of the most important methods to investigate the environmental impacts of the FRP.

Concentrating Photovoltaic—Thermal Systems
Numerous numerical and experimental studies have been conducted regarding the Concentrated Photovoltaic Thermal (CPVT) system because of its significant potential for efficient conversion of solar energy. The overall efficiency of the CPVT system is strongly dependent on the device, which extracts excess heat from photovoltaic cells. The most efficient cooling technology involves active cooling, which means that heat is collected from the photovoltaic (PV) cell via the forced flow of heat transfer fluid.

Renewable Energy and Energy Storage Systems
The use of fossil fuels has contributed to climate change and global warming, which has led to a growing need for renewable and ecologically friendly alternatives to these. It is accepted that renewable energy sources are the ideal option to substitute fossil fuels in the near future. Significant progress has been made to produce renewable energy sources with acceptable prices at a commercial scale, such as solar, wind, and biomass energies. Hybrid renewable energy systems are needed with good energy management to balance the various renewable energy sources’ production/consumption/storage.

Glycerol in nano oxides synthesis
The transformation of biomass and the utilization of all the by products derived from chemical conversion of biomass resources is one of the most important challenges nowadays. The impact in society and the level of awareness that already exists inside and outside the scientific community, makes the challenge of improving conversion of biomass to commodities a hot topic. Glycerol, a by-product obtained from the biodiesel production, is a key player compound due to its chemical versatility. The possibility of being used as solvent, reagent, reducing agent (in the polyol method), and so forth, makes glycerol an extremely appealing commodity. When used within nanotechnology, namely combined with nanomaterials, its potential becomes even higher.
