Potentiality of Vermicomposting
Vermicomposting is a biological process of decomposition of degradable residues through the digestive tracts of earthworms. It has been studied since long and still very important and relevant mostly in the viewpoint of organic waste recycling and biofertilizer production. Though wide range of literature are available on the topics, however, there are still unknowns that need to be additionally explored to maximize the potential of vermicompost.

Potentially Toxic Elements in Pharmaceutical Industrial Effluents
Potentially toxic elements (PTEs) are metallic chemicals with densities that are higher than that of water. Water pollution by PTEs due to the discharge of untreated pharmaceutical industrial effluents is a risk to human health and ecological integrity.

Power Generation in Sewage-Water Treatment Plants
Sewage-water treatment comprehends primary, secondary, and tertiary steps to produce reusable water after removing sewage contaminants. However, a sewage-water treatment plant is typically a power and energy consumer and produces high volumes of sewage sludge mainly generated in the primary and secondary steps. The use of more efficient anaerobic digestion of sewage water with sewage sludge can produce reasonable flowrates of biogas, which is shown to be a consolidated strategy towards the energy self-sufficiency and economic feasibility of sewage-water treatment plants. Anaerobic digestion can also reduce the carbon footprint of energy sources since the biogas produced can replace fossil fuels for electricity generation.

Practical Application of Temperature Indices in Horticulture
Temperature is the basic factor that differentiates vegetation around the world. All field experiments require the indication of the range of temperatures occurring in a given growing season. Temperature is an important factor determining fruit plant production, both in the growing season and in the winter dormant period. Various air temperature indicators were developed in a way that allowed the best possible description of adaptations of species, cultivars, and regions of adaptations to cultivation. They are based on experimentally obtained data and calculated optimal temperatures of growth and development of plants in particular development stages. In horticulture, the description of dependencies of the growth and development of plants on weather began to be accompanied with the development of simulation models.

Practical Application of Zeolites as Adsorbent
Zeolites are crystalline micro- and mesoporous materials widely used as catalysts and sorbents. Zeolites are commonly used in separation processes in, e.g., the petrochemical and pharmaceutical industries as they can be made fairly specific to the target molecules, and since the main mechanisms behind the separation process (molecular sieving, electrostatic interaction, and polarization) are always reversible, zeolites are believed (under ideal situations) to be able to undergo a virtually unlimited number of adsorption–desorption cycles. This is important from a cost-efficiency perspective too, as the high initial costs can be compensated by the longer life, assured by excellent stability and ease of regeneration.

Practices for Agricultural Climate Neutrality
Regarding the achievement of worldwide agricultural climate neutrality, the focus is on a worldwide net-zero emission of cradle-to-farmgate greenhouse gases (GHGs), while, when appropriate, including the biogeophysical impacts of practices on the longwave radiation balance.

PragerU
PragerU, short for Prager University, is an American non-profit organization that creates videos on various political, economic and philosophical topics from an American conservative or right-wing perspective. The organization was co-founded by talk show host and writer Dennis Prager and Allen Estrin. The videos are posted on YouTube and usually feature a speaker who lectures for about five minutes. The organization relies on donations, and much of its early funding came from fracking billionaires Dan and Farris Wilks. PragerU is not a university or academic institution. It does not hold classes, does not grant certifications or diplomas, and is not accredited by any recognized body.

Pre-Emptively Managing Overtourism
Overtourism is the congestion or overcrowding from an excess of tourists, resulting in conflicts with locals. The World Tourism Organization defines overtourism as "the impact of tourism on a destination, or parts thereof, that excessively influences perceived quality of life of citizens and/or quality of visitor experiences in a negative way".

Precambrian
The Precambrian (or Pre-Cambrian, sometimes abbreviated pЄ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time. The Precambrian (colored green in the timeline figure) is an informal unit of geologic time, subdivided into three eons (Hadean, Archean, Proterozoic) of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago (Ga) to the beginning of the Cambrian Period, about 541 million years ago (Ma), when hard-shelled creatures first appeared in abundance.
