Using Pyrolysis to Create Biochar
Pyrolysis is a combustion process of woody biomass conducted under low or no oxygen conditions. It converts any kind of biomass into biochar, bio-oil, or biogas. Hence plants’ woody material can also be converted into bioenergy products. Valorization of woody biomass in the form of energy-rich compound biochar is a more sustainable technique as compared to conventional burning which leads to toxicity to the environment. Innovations and the need to limit open burning have resulted in numerous mobile and fixed plant pyrolysis methods that burn a variety of woody residues.

Ākitio
Ākitio is a coastal community in the Tararua District of the lower east coast of the North Island of New Zealand. The Ākitio River runs for approximately 35 kilometres in a southeast by northwest direction, leading to the town of Weber, on Route 52, formerly State Highway 52. Ākitio is in meshblocks 2224200 (NW), 2224300 (N) and 2225100 (SW), which had a combined population of 111 people in 48 households in the 2013 New Zealand census.

Soil in Kilte Awula'ilo
The soils of the Kilte Awula’ilo woreda (district) in Tigray reflect its longstanding agricultural history, highly seasonal rainfall regime, relatively low temperatures, the presence of a wide depression at the foot of the Atsbi horst and steep slopes. Outstanding features in the soilscape are the wide ancient fluvial deposits, the soils of the granite batholith, cuestas and fertile lands behind tufa dams.

Membrane-Based Technologies for Post-Combustion CO2 Capture
Carbon dioxide (CO2), which results from fossil fuel combustion and industrial processes, accounts for a substantial part of the total anthropogenic greenhouse gases (GHGs). As a result, several carbon capture, utilization and storage (CCUS) technologies have been developed during the last decade. Chemical absorption, adsorption, cryogenic separation and membrane separation are the most widely used post-combustion CO2 capture technologies.

Microplastics in Freshwater
The low production costs and useful properties of synthetic polymers have led to their ubiquitous use, from food packaging and household products to high-tech applications in medicine and electronics. Incomplete recycling of plastic materials results in an accumulation of plastic waste, which slowly degrades to produce tiny plastic particles, commonly known as “microplastics” (MPs).

Seaweed Biorefineries for Carbon Capture and Storage
Seaweeds are among the most important biomass feedstocks for the production of third-generation biofuels. They are also efficient in carbon sequestration during growth and produce a variety of high-value chemicals. Given these characteristics together with the relatively high carbohydrate content, seaweeds have been discussed as an ideal means for CO2 capture and biofuel production.

Methods Suitable for Wide-Area Rainfall Rate Measurement
Many design principles for rain gauges that have the capacity to record rainfall intensity have been proposed or developed. For catchment-based studies, data distributed spatially is needed, particularly for localised convective storms. One approach to gathering such data are to install multiple gauges; however, it is also possible to adopt measurement methods that have the capability of recording area-wide intensity data.

Electric Vehicle Assignment Considering Users’ Waiting Time
A one-way electric-car-sharing system is an environmentally friendly option for urban transportation systems, which can reduce air pollution and traffic congestion with effective vehicle assignment. However, electric vehicle assignment usually faces a dilemma where an insufficient battery level cannot fulfill the requests of users. It greatly affects assignment choices and order fulfillment rates, resulting in the loss of platform profit. In this study, with the assumption that the users agree to wait for a period of time during which electric vehicles can be charged to fulfill trip demands, we proposed a waiting-time policy and introduced users’ utility to measure user retention.

Microcystin-LR in Primary Liver Cancers
Among all of the variants of MCs, MC-LR has been widely studied due to its severe hepatotoxicity. Since 1992, various studies have discovered the important role of MC-LR in the origin and progression of primary liver cancers (PLCs), while few reviews have focused on it. Based on the available literature, the mechanisms of how MC-LR induces or promotes PLCs are elucidated in this review. This review aims to enhance our understanding of the role that MC-LR plays in PCLs and provides a rational approach for future applications.
