Microfluidic approaches to microbubble production are generally disadvantaged by low yield and high susceptibility to (micro)channel blockages. This paper presents an alternative method of producing microbubbles of 2.6 μm mean diameter at concentrations in excess of 30 × 10(6) mL(-1). In this method, the nitrogen gas flowing inside the liquid jet is disintegrated into spray of microbubble when ...

mulberry (morus spp.) is a perennial tree cultivated for its foliage to rear the domesticated silkworm, bombyx mori l. mulberry has improved through conventional breeding in general aims to improve the quantity and quality of leaf yield, which have direct bearing on silk productivity. leaf senescence is one of the major constraints, which restricts the quantity of quality leaf availability for ...

Farmer adaptation to climatic variability is explored via an analysis of corn hybrid selection in southern Ontario. Corn hybrid varieties are available for a wide range of conditions, including accumulated heat, measured as Corn Heat Units (CHUS). Hybrids with higher CHU ratings generally have higher yields, so long as there is sufficient heat for them to mature. Farmers choose their hybrid var...

Arbuscular Mycorrhizal Fungi (AMF) are ubiquitous soil microorganisms playing a vital role in the functioning of agricultural ecosystems. Although AMF generally considered to have low host specificity, it has been suggested that modern plant breeding selected crop genotypes more selectively associated with AMF, possibly resulting high yielding varieties (HYV) having lower diversity than traditi...
