Influence of formulation properties on droplet size spectra and ground deposits of aerially-applied pesticides

Abstract: The influence of the physical properties of the spray liquid on droplet size spectra and ground deposits of aerially-applied pesticides was studied using heavy (high-viscosity) oil- and water-based suspensions of wettable powders (w.p.), a clear solution in a light (low-viscosity) oil, and an emulsion-suspension containing a bacterial control agent. The heavy oil provided a highly viscous spray medium, 52 to 64 mPa s (at a shear rate of 480 s−1), resulting in large droplet sizes and a high deposit on the ground sampling units. When the spray medium was thickened with petroleum jelly to keep the w.p. in suspension during overnight storage, the viscosity became excessively high (102 mPa s at 480 s−1), and the droplet spectrum was undesirably coarse and resulted in poor coverage of the spray plot and low deposits. The light-oil-based solution (ca 4 mPa s), provided a finer droplet spectrum and lower deposits than the heavy-oil-based formulations. The water-based suspensions of the w.p. (ca 2 mPa s), showed Newtonian behaviour, whereas the emulsion-suspension (ca 240 mPa s at 480 s−1) showed pseudoplastic behaviour. Consequently, the emulsion-suspension provided a markedly different droplet spectrum from that of the suspensions of the w.p. Nevertheless, all three aqueous media provided deposits comparable to those of the light-oil-based solution, markedly lower than the heavy-oil-based suspensions. The study indicated that highly viscous Newtonian formulations should be avoided in pesticide applications using Micronair AU3000 atomisers at the volume rate (4–7 litre ha−1) used here if high atomisation efficiency is required.

Prosperity and Productivity: A Canada-Australia Comparison

Abstract: This study compares Canada’s economic performance to Australia. The comparison is performed in terms of: a) living standards and its proximate sources of growth-labour productivity and labour utilization (or hours worked per person) and b) the underlying sources of labour productivity growth. There are marked differences in the structures of the labour market between the two countries, reflected by a more rapid growth in hours at work and labour utilization rate in Canada. However, this rapid growth in hours at work has muted Canada’s labour productivity growth, which increased less rapidly than its Australian counterpart.

Income Adequacy in Retirement: Accounting for the Annuitized Value of Wealth in Canada

Abstract: Discussions of pension adequacy for elderly Canadians have used the rate at which income falls with age — the income replacement rate or the ratio of post-retirement income to pre-retirement income. Use of income streams to assess post-retirement welfare requires a standard against which adequacy of the replacement rates can be judged. Because some expenditures (for example, work-related expenses) can be expected to fall after retirement, a declining income stream does not necessarily signal financial problems for seniors. More importantly, income as normally measured captures only part of what is available to seniors if households possess assets, which in retirement are not being used to generate measured income.This paper uses a different metric, referred to as "potential" income. Potential income is the sum of realized income and the income that could be realized from owned assets such as mutual funds and housing. Households prepare for retirement by saving and borrowing and investing the proceeds. The assets accumulated over a lifetime may or may not be drawn down in later years. If they are not, income streams underestimate the “potential” income available to support retirement. This paper takes this potential into account when comparing the pre- and post-retirement financial status of Canadian households.Based on data from the 1999 Survey of Financial Security, this analysis shows that when “potential income” is considered, households headed by seniors (aged 65 or older) compare much more favorably with younger households than when normally measured income is utilized. Indeed, when after-tax estimates are used, the potential income per adult-equivalent in senior households exceeds the income of households headed by younger adults.

Sampling sports during adolescence, exercise behaviour in adulthood, and the mediating role of perceived variety in exercise

Abstract: Objective: Physical activity levels decline from adolescence to adulthood, but participation in a variety of sports during childhood and adolescence (i.e., sampling) may increase physical activity ...
