RGB-D Data-Based Action Recognition
Early research on Human Action Recognition was dominated by the analysis of still images or videos, localizing the actor in a video spatio-temporally using bounding boxes, temporal extent, and a spatio-temporal cuboid which contains a particular action. Human Action Recognition has many applications, including the automated annotation of user videos, indexing and retrieving user videos, automated surveillance, monitoring elderly patients using specially adapted cameras, robot operations, and live blogging of actions. In recent times, the availability of massive amounts of video data has provided significance to the understanding of video data (through a sequence of images) with the possibility of solving problems such as scene identification, searching through video content, and interaction recognition through video scenes. RGB-D generally refers to Red, Green, Blue plus Depth data captured by RGB-D sensors. An RGB-D image provides a per-pixel depth information aligned with corresponding image pixels. An image formed through depth information is an image channel in which each pixel relates to a distance between the image plane and the corresponding object in the RGB image. The addition of depth information to conventional RGB image helps improve the accuracy and the denseness of the data.

Centralised Generation
Centralised generation refers the common process of electricity generation through large-scale centralised facilities, through Transmission lines to consumer. These facilities are usually located far away from consumers and distribute the electricity through high voltage transmission lines to a substation where it is then distributed to consumers. The basic concept being that incredibly large stations create electricity for a large group of people. The Vast majority of electricity used in Australia as well as the United States is created from Centralised Generation. Most Centralised Power Generation comes from large power plants run by fossil fuels such as coal or natural gas. Nuclear or large hydroelectricity plants are also commonly used. Many disagree with the processes of Centralised Generation as it often relies on electrical generation through processes of the combustion of fossil fuels, which are bad for the environment. However unsustainable the current system is, it is by far the most widely used, reliable and efficient system that is currently in use. Centralised Generation is fundamentally the opposite of distributed generation. Distributed generation is the small-scale generation of electricity to smaller groups of consumers. This can also include independently producing electricity by either solar or wind power. In recent years Distributed generation as has seen a spark in popularity due to its propensity to use renewable energy generation methods such as wind and solar.

Characterization of Semi-Solid Formulations
Specific aspects of semi-solid dosage forms for topical application include the nature of the barrier to be overcome, aspects of susceptibility to physical and chemical instability, and a greater influence of sensory perception. Advances in understanding the driving forces of skin penetration as well as the design principles and inner structure of formulations, provide a good basis for the more rational design of such dosage forms, which still often follow more traditional design approaches. The characterization of semi-solid dosage forms also requires specific approaches. In particular, rheology, chemical stability considering the specifics of semi-solid vehicles, and in vitro performance testing will be discussed.

Bioactive Compounds from Rice Varieties
Consumption of pigmented rice as a staple food is rapidly increasing due to their healthy prospective and considered as functional food ingredients. Greater interest has been shown in many color rice varieties due to their multiple biological activities. The phenolic compounds have been found to consist of anthocyanidins, ferulic acid, diferulates, anthocyanins and polymeric proanthocyanidins. Anthocyanin is located in the bran layers of the rice kernel, while phenolic acids are mainly present in the bran layers of rice, existing as free, conjugated and bound forms. Keeping in view the several health benefits associated with the functional ingredients, such as anti-inflammatory, antioxidative and anticancer effects, pigmented rice is considered as a functional food and food ingredient in many Asian countries.

Learning Crisis
The learning crisis is the reality that while the majority of children around the world attend school, a large proportion of them are not learning. A World Bank study found that "53 percent of children in low- and middle-income countries cannot read and understand a simple story by the end of primary school." While schooling has increased rapidly over the last few decades, learning has not followed suit. Many education systems leave lots of children behind in learning as they progress in schooling. For example, in India, over half of Grade 5 students have not mastered Grade 2 literacy. In Nigeria, only about 1 in 10 women who completed Grade 6 can read a single sentence in their native language. Across seven low- and middle-income countries that participated in PISA for Development, only 12 percent of children who were tested met minimum proficiency levels for math, and just 23 percent for reading. While the skills of Brazilian 15-year-olds have improved in recent decades, at the current rate of improvement, students will not meet the average score of wealthy countries in math for 75 years. For reading, it will take more than 260 years. It is highly likely that the learning crisis will be further exacerbated with the onset of the COVID-19 pandemic and the vast disruptions that this pandemic caused for education across the globe.

Nitroglycerin (Medication)
Nitroglycerin, also known as glyceryl trinitrate (GTN), is a medication used for heart failure, high blood pressure, anal fissures, painful periods, and to treat and prevent chest pain caused by decreased blood flow to the heart (angina) or due to the recreational use of cocaine. This includes chest pain from a heart attack. It is taken by mouth, under the tongue, applied to the skin, or by injection into a vein. Common side effects include headache and low blood pressure. The low blood pressure can be severe. It is unclear if use in pregnancy is safe for the baby. It should not be used together with medications within the sildenafil (PDE5 inhibitor) family due to the risk of low blood pressure. Nitroglycerin is in the nitrate family of medications. While it is not entirely clear how it works, it is believed to function by dilating blood vessels. Nitroglycerin was written about as early as 1846 and came into medical use in 1878. It is on the World Health Organization's List of Essential Medicines. The drug nitroglycerin (GTN) is a dilute form of the same chemical used as the explosive, nitroglycerin. Dilution makes it non-explosive. In 2019, it was the 184th most commonly prescribed medication in the United States, with more than 3 million prescriptions.

Virtual Fencing Technology for Cattle Management
Maximizing annual pasture consumption without negatively impacting individual cow performance is of great importance in grass-based dairy and beef systems due to pasture being the most cost-effective nutrient source. However, the disadvantages of conventional and electric fencing include material and labor costs and increased manual labor. Virtual fencing has been developed and evaluated for almost two decades. The evolution of precision livestock farming, specifically virtual fencing, presents new opportunities for maximizing the utilization of available pasture land. Virtual fencing technology decreases the labor involved in physical fencing, provides greater adaptability to changes in pasture conditions, increases precision and efficiency, and offers additional flexibility in grazing management practices. However, that innovative technology should be further developed, and improvements should include decreasing the total costs of the system and increasing its application to other technological groups of ruminants, e.g., suckler cows with calves, increasing the efficiency of the system operation in large areas and a larger number of animals.
