F the early 1900s to the late 1940s, road networks in South Australia were developed on the rectangular grid system as an extension to the original planning of early towns and villages. With the advent of the automobile and sealed pavements, most local government authorities constructed a sealed central strip approximately 6 meters wide with wide footpaths and verges around existing street tree...

one of the effective methods to improve the thermal efficiency of solar collectors is using nanofluids as the coolant. the present study experimentally investigated the effect of sio2/water nanofluid with 1% mass fraction on the performance of a symmetric collector, i.e. conical solar collector. the conical solar collector with 1 m2 area and normal to the earth was tested in ahvaz, a city in th...

erraneChron is GEMOC’s unique methodology for studying crustal evolution and evaluating the metallogenic potential of terranes. It is based on the integrated in situ analysis of zircons for U-Pb age, Hf-isotopic composition and trace-element composition using GEMOC’s laser-ablation-microprobe (LAM) ICPMS, LAM-Multi-Collector (MC) ICPMS and electron microprobe (EMP). The method can be applied t...

Melittosphex burmensis (Melittosphecidae) is an important apoid fossil from middle Cretaceous (,100 Ma) amber from Myanmar (Burma). Melittosphex exhibits a combination of wasp and bee features making it an important transitional form linking bees with crabronid wasps. The presence of branched hairs suggests that it was a pollen-collector and many aspects of the morphology suggest that it is mor...

Wireless sensor networks (WSNs) have been widely researched by countries and institutes. The limited node energy has already become a constraint of large-scale applications. Seeking the energybalance features at sensor nodes to prolong the network lifetime, a multi-track mobile data collecting mechanism (MTMDC) was proposed in this paper. The MTMDC mechanism was composed of three major phases: ...

To investigate the flotation separation behavior of petalite and quartz, various methods were employed in this study. These included micro-flotation experiments, a contact angle analysis, zeta potential Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron (XPS) to explore mechanism modified ether amine reagent (L0-503) for quartz under weakly alkaline conditions. The test results...

Abstract This simulation study focused on the hydrological effects of climate change and controlled drainage operated with subsurface drains an open collector ditch in agricultural field. The objective was to understand potential schemes for managing groundwater levels field water balance conditions projected take place Finland during 21st century representative concentration pathways 8.5 2.6. ...
