The objective of this study was to measure differences between arterial and venous blood gas parameters and to evaluate whether arterial blood gas values can be estimated from venous blood in Asiatic black bears (ABBs). Twelve healthy captive ABBs (8 males and 4 females; 8-16 years; 76.8-220 kg) were included in this study. The bears were immobilized with medetomidine and zolazepam-tiletamine u...

Abstract Based on disassembly studies, a life cycle assessment of the climate impact wireless over-ear headphone model Jabra Evolve2 85 (without charging station) is conducted regarding phases manufacturing, packaging, distribution, use and disposal. The total weight all components 280.7 g. materials can be categorized into polymers (61.7%), metals (20.9%), circuit boards (4.8%), Li-ion battery...

The simultaneous removal of SO2/NO2 by limestone slurry was studied in a gas-liquid bubbling reactor. Experiments were carried out to find the effect of various operating parameters such as inlet concentration of SO2 and NO2, reaction temperature, O2 content in the flue gas and additive on the SO2 and NO2 removal efficiencies. SO2 removal efficiency decreased with inlet NO2 concentration, react...

Sulfur dioxide (SO2) is a gaseous environmental pollutant which is routinely used in industry as a preservative and antimicrobial. Recent data suggests that SO2 may have value as a therapeutic agent. However, due to its gaseous nature, localizing SO2 generation is challenging. Herein, various 1,3-dihydrobenzo[c]thiophene 2,2-dioxides (benzosulfones) were prepared as candidates for photochemical...

Ghana is an important cocoa producer and exporter this production of high economic importance. Increasing interest in the sustainable productions cocoa/chocolate necessitated need to assess environmental impacts associated with different chocolate variants (extra dark (EDC), (DC), milk (MC) flavoured (FMC) Ghana, including identification hotspots for improvement. The life cycle assessment tool ...

With the support of a life cycle assessment model, this study estimates carbon footprint (CF) smartphones and costs (LCC) for consumers in scenarios where different material efficiency strategies are implemented Europe. Results show that major contribution to CF is due extraction processing materials following manufacturing parts: 10.7 kg CO2,eq/year, when assuming biennial replacement cycle. P...

[1] Measurements of gaseous nitrogen and sulfur oxide emissions in young aircraft exhaust plumes give insight into chemical oxidation processes inside aircraft engines. Particularly, the OH‐induced formation of nitrous acid (HONO) from nitrogen oxide (NO) and sulfuric acid (H2SO4) from sulfur dioxide (SO2) inside the turbine which is highly uncertain, need detailed analysis to address the clima...

Sulphur dioxide (SO2) has been used for centuries to minimize color in food processing and fruit and vegetable storage. In the sugar industry, it is used routinely by sugar beet processors to reduce and prevent color formation in white refined sugar. Sugarcane processors throughout the world use SO2 to produce plantation white sugars. This study was undertaken to determine the effect of SO2 on ...

[1] Long-range transport of sulfur dioxide (SO2) from east Asia to the central North Pacific troposphere was observed on transit flights during the NASA Transport and Chemical Evolution over the Pacific mission. A series of SO2-enhanced layers above the boundary layer was observed during these flights. The significant features included enhanced SO2 layers associated with low water vapor and low...
