Abstract. Plants with a strong activity to reduce the digestion of lipids from the diet are a possible way to prevent and combat obesity. This study evaluated 37 ethanol extracts of plants, some edible, medicinal, or belonging to a family that has the inhibitory activity of pancreatic lipase, aimed at looking for a new anti-obesity agent. Inhibition of pancreatic lipase (PL) was measured in vitro and in vivo assay. The plasma triacylglycerol levels after 1, 2, and 3 h in fasted male Wistar rats fed, by oral administration, with a lipid emulsion were measured. The antioxidant activities were evaluated using DPPH (1,1-diphenyl-2-picrylhydrazyl radical scavenging activity), FRAP (ferric reducing antioxidant power) and ABTS (2,2’-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid), and the total phenol and flavonoid content were determined. Nine plants exhibited low inhibition (˂41 %), nine showed medium inhibition (41-50 %), eight demonstrated high inhibition (51-60%) and 11 plants had the highest inhibition (≥ 61 %). Hibiscus rosa-sinensis, dried leaves extract displayed the highest inhibitory activity of pancreatic lipase 71.90 % at 400 µg/mL, with a dose-dependent inhibition against PL similar to orlistat. The kinetic study showed uncompetitive inhibition. Moreover, H. rosa sinensis extract also reduced the elevation of plasma triacylglycerol levels after lipid emulsion administration similar as orlistat did. H. rosa-sinensis dried leaves had higher antioxidant activity and total phenolic compounds than fresh leaves. H. rosa-sinensis presented the strongest anti-lipase activity and could be used as an anti-obesogenic agent or as a food additive to reduce the absorption of fats from the diet. Resumen. Las plantas con una fuerte actividad para reducir la digestión de los lípidos de la dieta son una posible forma de prevenir y combatir la obesidad. Este estudio evaluó 37 extractos etanólicos de plantas, algunas comestibles, medicinales o pertenecientes a una familia que tiene una actividad inhibitoria de la lipasa pancreática, con el objetivo de buscar un nuevo agente anti-obesogénico. Se medio la inhibición de la lipasa pancreática (PL) in vitro e in vivo, se midieron los niveles de triacilglicerol en plasma 1,2 y 3 h después de la administración oral de una emulsión lipídica a ratas Wistar machos en ayunas. Las actividades antioxidantes se evaluaron utilizando DPPH (1,1-diphenyl-2-picrylhydrazyl actividad atrapadora de radical), FRAP (poder antioxidante reductor del fierro) y ABTS acido (2,2’-azino-bis(3-ethylbenzthiazoline-6-sulphonico), también se midió el contenido total de fenoles y flavonoides. Nueve plantas exhibieron una inhibición baja (˂41 %), otras nueve con una inhibición media (41-50 %), ocho demostraron una inhibición alta (51-60 %) y once plantas mostraron la inhibición más alta (≥ 61 %). El extracto de hojas secas de Hibiscus rosa-sinensis, mostró la mayor actividad inhibitoria de la PL con un 71.90 % a 400 µg/mL, con una inhibición dependiente de la dosis contra PL similar a orlistat. El estudio cinético mostró una inhibición acompetitiva. Además, el extracto de H. rosa-sinensis también redujo la elevación de los niveles de triacilglicerol en plasma después de la administración de una emulsión de lípidos similar a como lo hace orlistat. Las hojas secas de H. rosea-sinensis tuvieron mayor actividad antioxidante y cantidad de compuestos fenólicos totales que las hojas frescas. H. rosa-sinensis presentó la mayor actividad anti-lipasa y podría usarse como un agente anti-obesogénico o como un aditivo alimentario para reducir la absorción de grasas de la dieta.

“…For (Karjalainen & Juhola, 2021), in particular, this ICT growth should be aimed towards low carbon enterprises, where extensive use of intelligent technologies may enhance the economy and speed up the move toward environmental sustainability. Complementary usage of ICT with the transportation system allows people to make choices that affect the total demand for transport and on alternative models, such as increasing the viability of working from home or promoting a switch in mobility modes (Ghaffar & El Aziz, 2021;Ren et al, 2020;Tang et al, 2020).…”

Intelligent Transportation Systems (ITS) have been shown to have positive effects on the economy and on efficiency, but this study aims to show that they also have a positive effect on carbon emissions. This article is based on the premise that implementing these technological steps is a winwin for long-term economic and ecological viability. The first research question asks if there is evidence that ITS systems can be implemented and operated in a way to generate environmental benefits, and the second asks if the policy priorities of national and international stakeholders reflect a propensity for ITS deployment in order to yield those benefits. Both fundamental drivers and a synthesis of the empirical facts are used to provide an answer to the first question. New propensity models to accomplish climatic and environmental objectives are one solution to the second problem. According to the findings, the likelihood that ITS would be included as a high priority policy instrument in future transport policies is significantly influenced by the Vehicle Density and High Technology exports of a country. The study's significance lies in its promotion of ITS as a policy instrument with the potential to improve economic performance and environmental performance. It's useful for transport planners and policy experts on a global, national, and even regional scale.

“…Common indicators include land utilization, material selection, and energy conservation, water efficiency, and waste and emissions minimization. In general terms, economic sustainability refers to practices that support economic growth in the long term without negative impacts on a community's social, environmental, and cultural spheres [14]. In the built environment economic sustainability focuses on reducing capital, operating, and disposal costs during the lifecycle of a facility.…”

Green building practitioners’ understanding of the concept of sustainability: South African perspective

The pursuit of sustainable development has resulted in a narrow focus on environmental sustainability in construction. In recent years, the concept of holistic sustainability in the construction sector has gained traction, with green-certified buildings being a major driver. However, studies have shown that green building certification does not necessarily embrace a holistic sustainability approach. Moreover, the misconceptualisation of sustainability has remained a barrier to the full adoption of sustainability principles in the industry. Under this premise, a study was carried out amongst practitioners on green-certified projects to explore their understanding of sustainability in construction. The study was conducted through semi-structured interviews with construction professionals, who were involved in green building certified projects. Findings reveal that although green building practitioners have a considerable understanding of the concept of sustainability, the certification process limits the operationalisation of the concept. The context of South Africa was used to generate results that are relevant to other contexts with similar settings and green certification tools. The implication of this study includes the need for further research on the operationalisation of social and economic sustainability concepts in green building certification.
