However, if we consider the impact of the shares of industry and of service in GDP on transport GHG emissions then the coefficient of determination is 0.914; but if we consider only the impact of the share of service in GDP on transport GHG emission the coefficient of determination is 0.895. keywords: analysis; capita; cluster; countries; environmental; gdp; ghg emissions; industry; service; transport ghg cache: fumecheng-3267.pdf plain text: fumecheng-3267.txt item: #163 of 407 id: fumecheng-3295 author: Filipović, Mirjana; Kevac, Ljubinko title: A NEW WINCH CONSTRUCTION FOR SMOOTH CABLE WINDING/UNWINDING date: 2017-12-09 words: 5911 flesch: 65 summary:  (13) From this moment on, the system for smooth cable winding/unwinding on the winch enters the period when angle i has values defined by: iii 32  (14) A wide application of the process of cable winding/unwinding on the winch is important; that is why it deserves a detailed analysis and it is the subject of this paper. keywords: angle; cable; fig; process; smooth; system; unwinding; winch; winding cache: fumecheng-3295.pdf plain text: fumecheng-3295.txt item: #164 of 407 id: fumecheng-3349 author: Đorđević, Milan; Stefanović, Velimir; Vukić, Mića; Mančić, Marko title: EXPERIMENTAL INVESTIGATION OF THE CONVECTIVE HEAT TRANSFER IN A SPIRALLY COILED CORRUGATED TUBE WITH RADIANT HEATING date: 2017-12-09 words: 5021 flesch: 43 summary: Secondary flows observed in the flow patterns, induced by the centrifugal force, significantly affect the flow field and heat transfer.

To conclude, Popov’s foundation, which serves as the basis for the MDR, represents a major advance in developing a unified approach to effective dealing with elastic contacts.

The microstructure of the as-built and CEBS treated EBAM Ti–6Al–4V samples was investigated using an Axiovert 40 Mat optical microscope (Carl Zeiss, Göttingen, Germany). keywords: bcc; beam; cebs; ebam; electron; fig; phase; samples; scratch; scratching; ti-6al-4v; titanium cache: fumecheng-9954.pdf plain text: fumecheng-9954.txt
