BACKGROUND Measuring eCo is rapid, non-invasive and inexpensive tool and correlate correctly with carboxyhemoglobin levels in blood. The aim of this study was to evaluate and compare the increase in end tidal carbon monoxide (eCO) levels in exhaled breath of passive smokers and healthy smokers after cigarette and shisha smoking. FINDINGS In a cross sectional study eCO levels were measured in ...

The paper combines original concepts about eco-energetic systems, in a transdisciplinary sustainable context. Firstly, it introduces the concept of M.E.N. (Mega-Eco-Nega-Watt), the eco-energetic paradigm based on three different but complementary ecological economic spaces: the Megawatt as needed energy, the Ecowatt as ecological energy, and the Negawatt as preserved energy. The paper also deal...

At present, overseas and domestic eco-security early warning research is in the exploratory stage. This paper uses Kizilsu Kirghiz Autonomous Prefecture as the research object and constructs an evaluation index system based on the pressure-state-response (P-S-R) conceptual model. This study analyzes eco-security early warning in the study area using the granger causality test model, the entropy...

The Eco RI-fragments of bacteriophage T5 DNA were mapped using a technique which involves primarily length measurements of molecules observed in the electron microscope. Since Eco RI cleavage generates termini with 4-nucleotide long cohesive ends, fragments of complete and partial Eco RI digests were covalently circularized with DNA ligase at dilute DNA concentrations before measuring relative ...
