Stratospheric aerosols (SAs) are a variable component of the Earth’s albedo that may be intentionally enhanced in the future to offset greenhouse gases (geoengineering). The role of tropospheric-sourced sulfur dioxide (SO2) in maintaining background SAs has been debated for decades without in situ measurements of SO2 at the tropical tropopause to inform this issue. Here we clarify the role of S...

Accurate estimation of emissions greenhouse gases (GHGs) is required for making effective climate change mitigation policies at the national level. Among major sources, municipal solid waste (MSW) an important source GHGs, such as methane (CH4), generated during anaerobic decomposition organic matter. In Viet Nam, GHGs are not well quantified, in particular from MSW management system. this stud...

Abstract Harnessing of second-generation feedstocks via circular economy approaches is generally considered as environmentally friendly. Nonetheless, different potential impacts can be caused during collection and transformation such feedstocks, affecting overall sustainability. Assessment particular importance when producing waste-based biofuels. In this regard, work’s aim was to carry out a s...

A biophysical whole farm system model was used to simulate the interaction between the historical climate, soil and pasture type at sites in southern Australia and assess the balance between productivity and greenhouse gas emissions (expressed in carbon dioxide equivalents, CO₂-eq.) intensity of beef cow-calf grazing systems. Four sites were chosen to represent a range of climatic zones, soil a...

The purpose of this study is to determine the energy use efficiency and greenhouse gas (GHG) emissions in peach production that took place Kırklareli province Turkey during 2020-2021 season. This includes calculations input, output, efficiency, specific energy, productivity, net input types, GHG ratio. Survey, observation data are related obtained from were collected 16 different farms (reachab...

Sulfur dioxide (SO2) is a major air pollutant, especially in developing countries. Many trees are seriously impaired by SO2, while other species can mitigate air pollution by absorbing this gas. Planting appropriate tree species near industrial complexes is critical for aesthetic value and pollution mitigation. In this study, six landscape tree species typical of a subtropical area were investi...

Bariatric surgery is considered an effective treatment for individuals with severe and complex obesity. Besides reducing weight and improving obesity related comorbidities such as diabetes, bariatric surgery could improve patients' health-related quality of life. However, the frequently used instrument to measure quality of life, the EQ-5D has not been validated for use in bariatric surgery, wh...

BACKGROUND The precise assessment of cerebral saturation changes during an inflammatory injury in the developing brain, such as seen in periventricular leukomalacia, is not well defined. This study investigated the impact of inflammation on locoregional cerebral oxygen saturation in a newborn rodent model using photoacoustic imaging. METHODS 1 mg/kg of lipopolysaccharide(LPS) diluted in salin...
