Invasive, polyphagous crop pests subsist on a number of crop and non-crop resources. While knowing the full range of host species is important, a seasonal investigation into the use of non-crop plants adjacent to cropping systems provide key insights into some of the factors determining local population dynamics. This study investigated the infestation of non-crop plants by the invasive Drosoph...

Phenological patterns have a great influence on community ecology. I have quantified fruit abundance using fruit traps, phenological transects, and observations on marked trees of selected species. All methods showed the main peaks of fleshy fruit production between the dry period and the middle of the rainy season. Wind, water, and mechanically dispersed seeds showed a peak of production at th...

The density of unripe kiwifruit (Actinidia deliciosa (A. Chev.) C.F. Liang et A.R. Ferguson cv. Hayward) early in storage was investigated as a means of determining the current fruit dry matter (DM) and total sugar-plus-starch concentrations, and of predicting DM and soluble solid concentrations later when the fruit had ripened. To investigate the robustness of the density relationships with DM...

R. Razavi, M. Fleury and M. Ghanbari By selecting from Bluetooth’s Enhanced Data Rate (EDR) packet types according to channel conditions, optimal data-rates are approached, especially if Forward Error Control (FEC) is extended to EDR. This Letter presents correct calculation of these packet types, which also accounts for Double Adjacent Error Correction (DAEC) in addition to conventional Single...

Dabai or Canarium odontophyllum Miq., from the family Burseraceae, is an important indigenous fruit to Borneo Island. However, it is a highly perishable fruit with short shelf life. Postharvest technology such as modified atmosphere packaging (MAP) can be used to maintain highly perishable fresh fruit quality and increase its shelf life. There is not much work has been carried out to study effe...

Recovering the true average abundance of the intracluster medium (ICM) is crucial for estimates of its global metal content, which in turn is linked to its past evolution and to the star formation history of the stellar component of the cluster. We analyze here how abundance gradients affect commonly adopted estimates of the average abundance, assuming various plausible ICM density and temperat...

The study diagnosed engineering properties on varying moisture content of sunflower seed and kernel from 7.6 to 25% (wet basis). On increasing moisture, dimensional values increased for both seed and kernel. Bulk density, true density and porosity were found higher for kernel as compared to seed at each moisture content. On increasing the moisture content from 7.6 to 25%, true density, porosity...

Average population density has been a traditional urban sprawl indicator, but it is insufficient to encapsulate its detrimental impacts. We demonstrate that cities of identical average may be subject very different levels car dependency, CO2 emissions and public budget deficits. To capture this, we shed light into the properties two “density-allocation” indicators: percentage land in which fall...
