This study investigated energy consumption and greenhouse gas (GHG) emission across various playing surfaces (e.g., greens, tees, fairways, and roughs) in an urban parkland golf course. The turfs of golf courses require frequent maintenance to ensure high aesthetic and play quality. Maintenance includes aeration, mowing, irrigation, and fertilization. The annual energy-based carbon footprint was found to be the highest for fairways, followed by greens, tees, and roughs. However, CO2 exchange in the grass was found [...]

Rural and remote communities are more vulnerable to damage caused by extreme events as compared to urban areas. Natural disasters can disrupt basic supplies such as domestic water supply and cooking needs in addition to electricity outages. The recognition of the interlinked nature of food, water and energy has gained momentum over the past few years. Smart Integrated Renewable Energy System (SIRES) has been proposed to handle basic needs such as cooking, domestic and irrigation water supply, and electricity to rem [...]

Investigating the historical origins of a well-accepted health program across a region, such as newborn screening in Latin America, has the potential to reveal the role of historically-specific drivers in shaping national health policy. We reviewed published reports on NBS in Latin America and interviewed newborn screening experts with experience in the region. We found trends suggesting that the decrease in infant mortality may be a prerequisite to investing in nationwide screening for rarer conditions. We also no [...]

The emission of greenhouse gases, specifically CO2, has reached non-acceptable levels causing global warming with adverse effects. Owing to rigorous ongoing research, these harmful substances might be converted to beneficial sources. The main objective of this study was to review the most effective processes that might utilize carbon dioxide to produce various substances, chemicals, and energy. For this, different existing and projected short-term and long-term strategies have been presented and discussed. Specific [...]

Regardless of their size, supported gold nanoparticles are largely used for liquid-phase oxidation reactions. Small gold nanoparticles exhibit good performance during the reduction of organic compounds. The direct reduction of carboxylic acid to aldehyde is a famous and familiar reaction in the field of organic chemistry and is considered as one of the fundamental chemical transformations. Herein, we present Au/hydrotalcite, Au/MgO, and Au/Al2O3 systems as heterogeneous versatile catalysts to realize the oxidation [...]

Biogas is an alternative to gaseous biofuels and is produced by the decomposition of biomass from substances such as animal waste, sewage sludge, and industrial effluents. Biogas is composed of methane, carbon dioxide, nitrogen, hydrogen, hydrogen sulfide, and oxygen. The anaerobic production of biogas can be made cheaper by designing a high throughput reactor and operating procedures. The parameters such as substrate type, particle size, temperature, pH, carbon/nitrogen (C/N) ratio, and inoculum concentration play [...]

A substantial share of the electric energy is generated with synchronous generators that provide sustained alternating current (AC) voltage and frequency energy to regional and national power systems, which subsequently transport and distribute it to diverse users. In an attempt to reduce environmental effects, electric energy markets have recently become more open, resulting in more flexible distributed electric power systems. In such distributed systems, stability, quick and efficient delivery, and control of ele [...]

It is recommended that children ages 3-5 receive 180 minutes of physical activity a day, with at least 60 minutes of moderate-to-vigorous physical activity. Despite these recommendations, a majority of preschoolers are not provided opportunities in the early childhood education setting to meet these daily recommendations through either structured or unstructured physical activity. Accordingly, the number of young children identified as overweight or obese over the past couple of decades has increased. Critical to a [...]

Mean monthly rainfall decline with continentality is a commonplace phenomenon that has been used in this study to compare its trend in Bamenda in the Western Highlands and Limbe on the Atlantic lowland coast. This study attempts to bridge some of the methodological gaps in the previous studies on rainfall variability in Cameroon that had emphasized only the inter-annual variability and coefficient of variation without focusing on the specific indices and contrasts between different ecological zones. In this study, [...]

The evolution of hominins, members of the zoological tribe Hominini, has been a much-studied topic, and the construction of phylogenetic trees has been the key method in molecular evolutionary studies. How scientists determine the phylogenetic trees are governed by the assumptions they place on the construction of similarities and differences in morphological traits, the differences in the number of base pairs in the genomes, and the number of similar gene clusters that code for traits (haplotypes) or are error seq [...]
