Non-Invasive Sweat Diagnostics Wearable Biosensors
Wearable bioelectronics has received tremendous attention worldwide due to its great a potential for predictive medical modeling and allowing for personalized point-of-care-testing (POCT). Since the distribution of sweat glands in the human body is rich (>100 glands/cm2) and the sweat contains abundant biochemical compounds, human sweat has become a promising bio-fluid for non-invasive biosensing. Since nearly every portion of human skin has eccrine glands, sweat is readily available without the use of needles or other invasive devices. Iontophoresis sweat can be extracted from anywhere which is not possible in any other case of bio-fluids. Moreover, analytes including ions, metabolites, acids, hormones, and small proteins and peptides are partitioned into the sweat. Sweat also contains various electrolytes (such as potassium, sodium, chloride, and calcium), nitrogen-containing compounds (such as urea and amino acids), as well as metabolites such as glucose, lactic acid, and uric acid, along with xenobiotics such as drugs and ethanol.

Unsaturated Fat
An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain. A fatty acid chain is monounsaturated if it contains one double bond, and polyunsaturated if it contains more than one double bond. Where double bonds are formed, hydrogen atoms are subtracted from the carbon chain. Thus, a saturated fat has no double bonds, has the maximum number of hydrogens bonded to the carbons, and therefore is "saturated" with hydrogen atoms. In cellular metabolism, unsaturated fat molecules contain somewhat less energy (i.e., fewer calories) than an equivalent amount of saturated fat. The greater the degree of unsaturation in a fatty acid (i.e., the more double bonds in the fatty acid) the more vulnerable it is to lipid peroxidation (rancidity). Antioxidants can protect unsaturated fat from lipid peroxidation.

Degrowth
Degrowth (French: décroissance) is a political, economic, and social movement based on ecological economics, anti-consumerist and anti-capitalist ideas. It is also considered an essential economic strategy responding to the limits-to-growth dilemma (see The Path to Degrowth in Overdeveloped Countries and post-growth). Degrowth thinkers and activists advocate for the downscaling of production and consumption—the contraction of economies—arguing that overconsumption lies at the root of long term environmental issues and social inequalities. Key to the concept of degrowth is that reducing consumption does not require individual martyring or a decrease in well-being. Rather, "degrowthers" aim to maximize happiness and well-being through non-consumptive means—sharing work, consuming less, while devoting more time to art, music, family, nature, culture and community.

Foams in Wastewater Treatment Plants
The formation of persistent foams can be a critical problem in wastewater treatment plants (WWTPs) as it could lead to a series of operational problems, especially the reduction of the overall system performance. To date, the effects of foaming in the WWTPs are a problem that is currently very common and shared, but which to date is treated mainly only at the management level and still too little studied through a globally shared scientific method: the complexity of the phenomenon and the systems have led to numerous partially contradictory descriptions and hypotheses over the years. The goal must be to suggest future research directions and indicate promising strategies to prevent or control the formation of foams in WWTPs. This study examines and investigates the problem of foams by a methodological approach of research through a review on the state of the art: the factors influencing the formation of foams are described first (such as surfactants and/or extracellular polymeric substances (EPSs)), then the known methods for the evaluation of foaming, both direct and indirect, are presented, with the aim of identifying the correct and best (from the management point of view) control and/or prevention strategies to be applied in the future in WWTPs.

Congenital Microcoria
Iris integrity is required to regulate both the amount of light reaching the retina and intraocular pressure (IOP), with elevated IOP being a major risk factor for glaucoma. Congenital microcoria (MCOR) is an extremely rare, autosomal dominant disease affecting iris development and hindering both of these functions.

Thermal Energy Storage for Grid Applications
Thermal energy systems (TES) contribute to the on-going process that leads to higher integration among different energy systems, with the aim of reaching a cleaner, more flexible and sustainable use of the energy resources. Energy storage is also a key component of decarbonisation scenarios, such as the ones indicated in the European Roadmap to 2050, whose main targets include high energy efficiency, diversification of the production resources, and increase in the percentage of renewable energy sources (RES). TES-based solutions in systems connected to the electrical grid facilitate the energy system integration to get additional flexibility for energy management, enable better use of variable renewable energy sources (RES), and contribute to the modernisation of the energy system infrastructures.

Catalytic Mechanism of Photocatalysts Based on GCN Heterogeneous
In the current world situation, population and industrial growth have become major problems for energy and environmental concerns. Extremely noxious pollutants such as heavy metal ions, dyes, antibiotics, phenols, and pesticides in water are the main causes behind deprived water quality leading to inadequate access to clean water. In this connection, graphite carbon nitride (GCN or g-C3N4) a nonmetallic polymeric material has been utilized extensively as a visible-light-responsive photocatalyst for a variety of environmental applications.

Nurses' Health Study
The Nurses' Health Study is a series of prospective studies that examine epidemiology and the long-term effects of nutrition, hormones, environment, and nurses' work-life on health and disease development. The studies have been among the largest investigations into risk factors for major chronic diseases ever conducted. The Nurses' Health Studies have led to many insights on health and well-being, including cancer prevention, cardiovascular disease, and type 2 diabetes. They have included clinicians, epidemiologists, and statisticians at the Channing Laboratory (of Brigham and Women's Hospital), Harvard Medical School, Harvard School of Public Health, and several Harvard-affiliated hospitals, including Brigham and Women's Hospital, Dana–Farber Cancer Institute, Children's Hospital Boston, and Beth Israel Deaconess Medical Center.

Microwave-Assisted Pyrolysis of Waste Plastics
Microwave treatment, owning specific interactions between the electric field and the molecules of treated materials, presents potential advantages in the application of plastic pyrolysis. High value-added liquid oil, gas and solid carbon can be obtained from microwave-assisted pyrolysis (MAP) of plastics. Factors that affect the distribution of pyrolysis products of plastics include the properties of plastics, microwave treatment parameters, microwave absorber, co-pyrolysis, catalysts and reactor design. MAP of plastics has broad application prospects, and large-scale pyrolysis processing devices need to be developed. At the same time, the research platform of MAP simulation of plastics still needs to be developed.

Milk Bioactive Compounds
The milk fat fraction is a rich source of nutrients and bioactive factors. This fraction is composed of milk fat globules (MFGs) surrounded by the milk fat globule membrane (MFGM). In this review we revise the literature that deals two minor topics that characterize the milk fat fraction. The first topic is the MFGM proteome, which has several bioactive properties and shows similarities and variations among species and phases of lactation. The second topic is the content of essential nutrients among MFGs and MFGM, named minerals and lipophilic vitamins, in order to assess the nutrifunctional role of the milk fat fraction.

Humani Generis
Humani generis is a papal encyclical that Pope Pius XII promulgated on 12 August 1950 "concerning some false opinions threatening to undermine the foundations of Catholic Doctrine". Theological opinions and doctrines known as Nouvelle Théologie or neo-modernism and their consequences on the Church were its primary subject. Reginald Garrigou-Lagrange (1877–1964), professor of the Pontifical University of Saint Thomas Aquinas Angelicum, is said to have been a dominant influence on the content of the encyclical.

Type
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralize the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution.

Oleaginous Red Yeasts: Concomitant Producers of Triacylglycerides and Carotenoids
Oleaginous red yeast species are colourful (usually having orange-pink-red hues) single cell microorganisms capable of producing valuable bioproducts including triacylglycerides (TAGs) for biodiesel and carotenoids for nutraceuticals. The name “oleaginous yeasts” is conferred based on their ability to synthesize and accumulate TAGs to over 20% of their dry cell weight. Their colours are indicative of the presence of the major carotenoids present in them.

Digital Transformation for Higher Education in South Africa
COVID-19 has left an unmistakable impression on the world stage. It has altered the global socio-economic landscape, forcing individuals to adapt and embrace new ways of doing business, as well as new ways of life. One of the most significant effects of the pandemic was to hasten the adoption of digital technologies by many areas of the global economy. Campus closures were observed in the higher education sector, putting an end to long-standing face-to-face teaching and learning. This necessitated the most rapid paradigm shift ever seen in this industry to continue educating and learning. An abrupt change to online learning, which is primarily reliant on digital technologies, occurred.
