Dynamics of biofilm processes in an annular reactor
… is a general term referring 1 to the undesirable development of biofilms on surfaces exposed to aqueous environments. In water distribution systems and heat transfer equipment, biological fouling can cause substantial energy losses resulting from increased fluid frictional resistance and increased …

Understanding the thermal biology of macadamia nut borer, Thaumato(bia batrachopa (Meyrick) (Lepidoptera: Tortricidae): a pest of macadamia in South Africa
… no evidence on the role of temperature on the development duraSon of T. batrachopa life stages, nor the outcomes regarding developmental rates and thermal responses. Understanding the mechanisms through which the temperature affects T. batrachopa’s life stages should contribute to developing a …

Endoparasites of working donkeys in Ethiopia: epidemiological study and mathematical modelling
… output, and in simulating anthelmintic control strategy. The model is based on parameters of biological development of cyathostomins and climatic data. A good fit of the model prediction to the field data was obtained after some parameter adjustments. The development rate of ingested larvae to egg …

Improving the development of bovine in vitro produced embryos cultured individually
… over two experiments would increase development of individually cultured embryos to that of group cultured embryos. In the first experiment both the addition of serum/serum replacer and a co-culture with bovine granulosa cells were applied to individually cultured embryos in a 3x2 …

Population studies of the potato leafhopper, Empoasca fabae (Harris), on alfalfa, Medicago sativa L.
… ® manufactured by D-Vac Co., Riverside, Calif.). Developmental rates for eggs and nymphs and ovipositional rates of adult females in laboratory studies were determined at several temperatures. Egg and nymphal development rate increased with increasing temperatures from 13 to 32°C. The development …

Managing choice in research and development
… and potential markets. The value of research and development (R&D) lies primarily in creating choices; R&D managers add value by managing choice effectively. An approach has been developed to align portfolio balance with strategic balance in managing R&D. A system dynamics model is used for …

Effects of Temperature and Dissolved Oxygen on Development and Survival of Embryos in Nests of Bluehead Chub Nocomis leptocephalus
… factors that shape metabolic demand, developmental rate, and survival in fish embryos. Because embryos rely entirely on diffusion for oxygen uptake and cannot move away from stressful conditions, even small shifts in temperature or oxygen availability can strongly influence early …

The plasticity of life histories during larval development and metamorphosis, using amphibians as study organisms.
The ability of animals to vary growth, development rate and behaviour in response to environmental conditions has been well documented, particularly during the larval phase in animals with complex life cycles. The evolution and maintenance of plasticity in response to environmental conditions is …

Developmental timing of pupation and analysis of color pattern response to thermal stress in Bombus impatiens (Hymenoptera: Apidae)
… environmental component known to impact the development rate, metabolism, and color pattern formation of many insects. As yet, the extent to which environmental temperatures affect the physiological development underlying color pattern phenotypes in bumble bees is unknown. To that end, I …

A Temperature-Dependent Development Model for Willow Beetle Species (Coleoptera: Chrysomelidae) in Ireland: Simulation of Phenology/Voltinism in Response to Climate Change
… and photoperiod, but also host plant, on beetle development were investigated. Constant temperature experiments showed that development time for all assessed life-cycle stages decreased as temperature increased. P. vulgatissima oviposition period and total fecundity were influenced by temperature …

IN VITRO EMBRYO PRODUCTION IN WOOD BISON (Bison bison athabascae)
… morphological characteristic, and on blastocyst development rate, was also investigated. Compact COC classified as good (>3 layers of cumulus cells) resulted in the highest blastocyst rate following in vitro maturation, fertilization and culture. There was no effect of extending the FSH …

Bionomics of the anthocorid, Orius insidiosus (Say) in Virginia apple orchards
… currently being developed. Egg and nymphal development of O. insidiosus was studied at 17°, 23°, 29°, and 35°C. Nymphs were supplied with an excess of the European red mite, Panonychus ulmi (Koch). There was a linear relationship between development rate (l/Days) of O. insidiosus and …
