Emerging countries in Southeast Asia are facing considerable challenges addressing rising motorisation and its negative impact on air quality, traffic, energy security, liveability, greenhouse gas emissions. This paper presents a comparative analysis of the approach status sustainable, low-carbon transport policy ASEAN identifies differences similarities. The methodology is based taxonomy components as developed by Howlett Cashore. data come from comprehensive country studies for Indonesia,...
This study presents the results of a work employing Evaluation by an Area-based Method Ranking (EAMR) methodology to address Multi-Objective Optimization Problem (MOOP) two-stage helical gearbox comprising two gear sets in initial stage. The objective this is identify most critical design parameters for minimizing volume while optimizing its efficiency. In study, three key were selected analysis: wheel face width coefficients Xba first and second stages, as well ratio stage u1. Furthermore,...
Objective: To assess the value of ABC score in predicting early rebleeding and - hospital mortality cirrhotic patients with acute variceal bleeding (AVB). Subject method: cross-sectional descriptive study carried out on 201 AVB 108 military central between September 2022 April 2023. compare rate mortality. Results: had a good prognostic power (0,804; 95%CI: 0,70 – 0,91; p <0,001), at cut-off 8, 81.0% Se, 79,4% Sp) an acceptable re-bleeding (AUROC 0,744; 0,59 0,89; = 0,002), 9, 62,5% Se...
This article introduces a study on the optimal calculation of gear ratios two-stage helical reducer. In study, acreage cross section reducer was chosen as objective function optimization problem. Also, design equation for pitting resistance set investigated. Furthermore, equations moment equilibrium condition and their regular were analysed. A computer program performed to determine partial transmission getting minimal system. From results program, two models determining proposed. Using...
This paper presents a new study on optimum calculation of partial ratios three-step helical gearboxes.The chosen objective function is the cross section dimension gearbox.In solving optimization problem, design equation for pitting resistance gear set was investigated and equations moment equilibrium condition mechanic system including three units their regular are analyses.From results study, effective formula determination gearboxes introduced.As formulas explicit, can be calculated...
Stack gas and fly ash samples were collected in two steel plants three cement kiln for the determination of polychlorinated dibenzo-p-dioxins dibenzofurans (PCDD/Fs). A standard sampling method (U.S EPA 23) was used following requirements isokinetic stack emission. The quantification PCDD/Fs done by high resolution chromatography, coupled with mass spectrometry (HRGC/HRMS). results demonstrated that PCDD/F concentrations varied from 0.234 to 0.577 ng/Nm3 on a basis, 0.048 0.166 TEQ basis. In...
FT-Raman spectra were obtained from undyed poplin cotton fabric and the same differently dyed with a bi-functional reactive dye, Cibacron C (molecular structure unknown); four series of samples each contained dye in different form—unfixed, ammonia-treated/unfixed, fixed, ammonia-treated/fixed. The dominated by but states not obviously differentiated. Application principal component analysis showed that spectral groups can be discriminated other cotton. Further, for fabrics, which contain...
