Modern internal combustion engine vehicles carry extensive exhaust aftertreatment systems that have the potential to reduce their tailpipe pollutant emissions near-zero, or even within zero levels of measurement equipment in real-world conditions. It has been reported, therefore, such lower than air intake vehicle – they are cleaning ambient air. This study investigates this hypothesis using a ...
BACKGROUND Polychlorinated dibenzo-p-dioxins (PCDD) and dibenzofurans (PCDFs) are highly toxic persistent organic pollutants (POPs), which can cause various health outcomes, such as cancer. As a part of the National and Sub-national Burden of Disease Study (NASBOD), we aimed to estimate dioxins and furans national emissions, identify their main sources, estimate daily intake doses, and assess t...
The present study was undertaken to study different methodological aspects of quantifying CO2 production and milk intake of suckling piglets using the doubly labelled water (DLW) technique. In total, 37 piglets were enriched intraperitoneally with DLW to study equilibration time of 18O (n = 3), to validate the estimation of milk intake and CO2 production (n = 10) of piglets fed milk replacer an...
For many years, global researches that focus on improving soil fertility have been conducted. Nowadays, innovative inculcations of environmentally (ecologically) friendly organic agriculture are becoming quite popular. One the most effective indicators is use alternative types fertilizers. As part large-scale experiments, researchers propose to fertilizers made from sapropel concentrated in fre...
Abstract Ventilation system affects the water evaporation rate, energy consumption and paper quality, which is considered as largest optimization potential part of multi-cylinder dryer section. In this paper, models section are constructed by combining modules moisture evaporation, heat recovery system, air heaters, supply exhaust air. Taking a corrugated machine an example, ventilation influen...
The flexibility of a crankshaft exhibits significant nonlinearities in the analysis diesel engines performance, particularly at rotational speeds around 2000 rpm. Given explainable mathematical trends analytical model and lack available modeling intake manifold with flexible crankshaft, present study develops validates such model. In paper, mass flow rate air that goes from into all cylinders e...
