The point of zero charge (PZC) is an inherent electrokinetic property of biochars (BC). It influences the adsorption process under certain pH conditions. Herein, we report the method of determination of the PZC values of ten standard BCs. We used the salt addition method to select the BCs with suitable properties for methylene blue (MB) removal from aqueous solutions. The standard BCs were obtained by pyrolyzing five different biomasses at two distinct temperatures (550°C and 700°C). The BCs derived from rice husk [...]

The omega-3 long-chain polyunsaturated fatty acids (omega-3 LC-PUFAs) family includes eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and docosapentaenoic acid (DPA). Although seafood is the richest source of omega-3 LC-PUFAs, because diet alone is often insufficient in older people, they may require food supplements and enriched food as sources of omega-3 LC-PUFAs. It has been reported that long-term intake of 3-5 g/d EPA + DHA as supplements is safe for adults; omega-3 LC-PUFAs exert cardio-metabolic pro [...]

Studies in the field of neuroscience have shown that the neural network responsible for numeracy overlaps with the visual and spatial processing regions. Other studies in psychology also highlighted an association of visual-spatial processing with mathematical competence at the early stages of development. These findings suggest that research on the size of the focal area of attention (consciousness) can contribute to understanding the development of numeracy. In this case study, we verified the hypothesis of devel [...]

Chair yoga is a specific form of yoga practiced while seated on a chair, or standing using a chair for support; this adaptation allows those with impaired standing ability to practice safely. The purpose of this scoping review was to analyze the published literature regarding the use of chair/adapted yoga with older adults. Two researchers performed the review. Data sources: PubMed Central, CINAHL, Medline Full Text, Nursing and Allied Health, SPORT discus and TRIP were accessed. Study selection: Inclusion criteria [...]

The process of light-induced C-H oxygenation is of high interest as it can be used for the construction of oxygenated compounds. Herein, we report a mild and general method for the efficient synthesis of aromatic ketones following the process of metal-free C-H oxygenation. With air as the oxidant, high functional tolerance was demonstrated, and the desired ketones were obtained in moderate to excellent yields at room temperature (25 oC). Mechanistic studies suggested that the oxidative transformation potentially oc [...]

Enzymes are extensively used in biotechnological processes in several areas of industry. They are sustainable and safe, and their specificity is another characteristic that improves the performance in the process. Among enzymes, lipase is relevant due to the ability to play different roles in the industry and the possibility of collecting them from microbial sources that are found in industrial residues. This can reduce the costs of enzyme production. In relation to that, lipase immobilization is an interesting pro [...]

The urban heat island (UHI) effect is not well understood, especially within the cityscape. This editorial is from the perspective of an undergraduate student Cadet Emma Larsen, as she comes to understand the UHI through mentorship from professors Simon Ghanat and Scott Curtis, personal experiences as a cadet at a military academy in Charleston, SC, USA, and active learning through participation in a national heat observation campaign, the NOAA HeatWatch, and related independent research. HeatWatch seeks to underst [...]

One of the biggest challenges currently presented to organisations worldwide is their ability to identify and sustainably manage greenhouse gas emissions. ‘Carbon management’, as it is referred to, is the process of understanding how and where an organisation’s activities generate emissions, and extends beyond meeting regulation requirements to being strategically utilised within businesses for social licensing, financial planning and corporate decision-making. The aim of this research is to analy [...]

After the emergence of Mindfulness in the Western world, many studies proved its mental and physical benefits. However, implementing Mindfulness in psychotherapy has several challenges: therapists are not formal Mindfulness instructors; the Mindfulness course is a continuous eight-week course, which many patients do not attend during therapy, while others attend and drop out. Thus, Hypnosis was applied to shorten and strengthen the desired changes. The article describes the logic behind this integration, demonstrat [...]
