Analyses taken over all observed weather conditions of daily 0600 EST climate data from a network monitoring stations in and around the large city Melbourne, Australia, revealed 20-yr mean urban heat island (UHI) value 1.13°C. The UHI varied seasonally between summer (1.29°C), spring (1.25°C), autumn (1.02°C), winter (0.98°C). Investigations undertaken with wind speed cloud amount enabled detailed investigation relative importance factors such as turbulent radiative exchanges on Melbourne's...
This paper examines the characteristics of urban heat island (UHI) in a large Australian city (Melbourne) using local area weather data and US National Centers for Environmental Prediction (NCEP) reanalyses mean sea level pressure (MSLP). Conventional methods to determine UHI from climatological often involve comparing minimum temperature between rural environments. The findings presented this show that simultaneous measurements at one three nearby airport sites 0600 (Australian eastern...
Summary Light is essential for photosynthesis; however, excess light can increase the accumulation of photoinhibitory reactive oxygen species that reduce photosynthetic efficiency. Plants have evolved photoprotective non-photochemical quenching (NPQ) pathways to dissipate energy. In tobacco and soybean (C 3 plants), overexpression three NPQ genes, violaxanthin de-epoxidas e ( V DE), Photosystem II Subunit S P sbS), zeaxanthin epoxidase Z EP), hereafter VPZ, resulted in faster induction...
<title>Abstract</title> Identifying loci conferring resistance to geminiviruses is an on-going priority in diverse crop species. Multiple geminivirus QTLs and genes have been described, including most recently DNA polymerase delta subunit 1 (<italic>POLD1</italic>) both cassava tomato. From this, we hypothesized that POLD1-mediated present a broad range of plant An analysis multiple species with published was done identify POLD1 variation consistent known alleles. Further, allele mining over...
The coronavirus disease 2019 (COVID-19) pandemic necessitated using telehealth to bridge the clinical gap, but could increase health disparities. This article reports on a chart review of diabetes visits occurring before COVID-19, during shelter-in-place orders, and reopening period. Visits for children with public insurance those who were non-English speaking identified. Telehealth increased from 26.2% COVID-19 37.3% orders 34.3% reopening. 3.5% 17.5% remained at 15.0% Pandemic-related...
Purpose Wi‐Fi technologies enable small‐scale, bottom‐up development of community networks in (rural) under‐serviced areas developing countries. The purpose this paper is to examine: the constraints and opportunities that small providers have faced date their endeavors develop South Africa; extent which newly introduced Electronic Communications Act 2006 might alleviate any constraints. Design/methodology/approach Through interviews document analysis analyzes regulations license application...
A pulsed detonation tube (PDT) is operated at initial pressures equal to and greater than 1 atm in order evaluate the effect of these on relative gains achieved by a converging-diverging nozzle, while ambient pressure maintained atm. Local heat flux measured determined play significant role overall energy release during blowdown, especially when converging -diverging nozzle implemented. With addition decrease Isp observed low (near atm) , whereas becomes beneficial higher (above 2 .
We report qualitative planar laser-induced fluorescence (PLIF) imaging experiments of supersonic reactive flows over a wedge test-body in an expansion tube. Both hydrogen-based and ethylene-based mixtures were investigated this work. Ongoing facility characterization efforts three different freestream conditions, Moo = 6.7, 5.2, 4.2. These conditions used initial investigation combustion modes around 40°half-angle wedge. In several cases, shock-induced was observed finite distance behind the...
Performance impact of a converging-diverging nozzle on pulsed detonation engine (PDE) is studied experimentally. Thrust and specific impulse are determined from integrated pressure measurements. Burned gas velocity obtained optical measurements seeded cesium atom. Comparison measured quantities with prediction finite-rate chemistry computational fluid dynamics (CFD) models indicate heat transfer plays significant role at late times during blowdown.
