The traffic conditions in developing nations of Asia are highly heterogeneous due to the presence of various vehicle types. The objectives of this paper are as follows. To study the road traffic capacity and delays at urban merging sections consisting of the mixed traffic stream. To analyse the interactions of vehicles both laterally and longitudinally by the inclusion of vehicle-type dependent factor. Using the data collected at a five-lane urban merging section using video recording method for the evaluation. To study the relation between macroscopic parameters (speed, flow, density, occupancy) and microscopic parameters (lateral clearance, average gap, space headway, lateral movement duration) is established by considering vehicle-type dependent factor. To analyse the effect of overtaking characteristics of different vehicle types at merge sections under mixed traffic conditions. The findings from this present research help in the operational analysis of merging locations on high-speed urban roads in Malaysia.

Coccolithophores are important contributors to global calcium carbonate through their species-specific production of calcite coccoliths. Nannofossil coccolith calcite remains an important tool for paleoreconstructions through geochemical analysis of isotopic and trace element incorporation, including Sr, which is a potential indicator of past surface ocean temperature and productivity. Scyphosphaera apsteinii exhibits an unusually high Sr/Ca ratio and correspondingly high partitioning coefficient (DSr) in their two morphologically distinct types of coccoliths. Whether or not this reflects mechanistic differences in calcification compared to other coccolithophores is unknown. We therefore examined the possible role of Sr in S. apsteinii calcification by growing cells in deplete, ambient, and higher than ambient Sr conditions (between 0.33 - 140 mmol/mol Sr/Ca). The effects on growth, quantum efficiency of photosystem II (Fv/Fm), coccolith morphology, and calcite DSr were evaluated. Reducing the Sr/Ca from ambient (9 mmol/mol) did not significantly alter the frequency of malformed and aberrant muroliths and lopadoliths, but at higher than ambient Sr/Ca conditions coccolith morphology was significantly disrupted. This implies that Sr is not a critical determining factor in normal coccolith calcite morphology in this dimorphic species. Interestingly, muroliths had significantly lower Sr/Ca than lopadoliths at ambient and elevated [Sr], and lopadolith tips had lower Sr than bases in ambient conditions. In summary, the Sr fractionation behavior of S. apsteinii is unusual because of an overall high DSr, and an inter- and intra-coccolith variability in Sr/Ca. We hypothesize that differential Sr-and Ca-binding capacity of coccolith associated polysaccharides may account for the unusual Sr fractionation of this species which can explain all observations made in this study.

Monotonic dataset for 3D printed composites samples reinforced with long continuous fibers. Mechanical properties under monotonic loads were studied for different kinds of printing configurations. Tensile monotonic tests under controlled displacement were performed until sample´s rupture. The data is presented as plain text files without any analysis. A preliminary data analysis has been published already somewhere else [doi:10.1016/j.ijfatigue.2019.105275]. The text files contain, time, displacement, and force. The data is useful for design engineers and researchers involved with AM when new models specifically tailored for CFRTPC are available.

Total RNA was purified from E. pacifica using with an RNeasy Lipid tissue mini kit. The library of E. pacifica for next generation sequencing was made using with a TruSeq RNA library prep kit v2 (Illumina). RNA purification and library preparation were performed according to the manufacturers’ instructions. The library was analyzed by Miseq using a Miseq reagent kit v3 (600 cycle) (Illumina). The fastaq data was assembled by Trinity.
