  • Produce Grower, August 2017 issue

    There may be no such thing as a perfect tomato, but due to research by Amy Bowen and Dave Liscombe at the Vineland Research and Innovation Centre, growers are one step closer to producing great ones. In 2012, the Ontario Greenhouse Vegetable Growers put out a list of research priorities, and one of those priorities was to improve or differentiate flavor in tomatoes. The focus was on tomatoes on ...

  • Habitat‐specific foraging and sex determine mercury concentations in sympatric benthic and limnetic ecotypes of threespine stickleback

    Mercury (Hg) is a widespread environmental contaminant known for the neurotoxicity of the methylated forms, especially monomethyl mercury, which bioaccumulates and biomagnifies in aquatic food webs. Mercury bioaccumulation and biomagnification rates are known to vary among species utilizing different food webs (benthic versus limnetic) within and between systems. We assessed if carbon and ...

  • Will Stainless Steel Production Costs Rise on Indonesia Export Ban?

    The Indonesia government finally pushed through a ban on exporting unprocessed exports of nickel and bauxite ore, in a move aimed at forcing companies to refine the minerals on Indonesian soil and then export to increase the value of exports. State owned Indonesian miner, Antam stated that it expects nickel ore production to decline by 87% in 2014 compared to last year, as it plans to now meet ...

  • Phytase supplemented poultry diets affect soluble phosphorus and nitrogen in manure and manure-amended soil

    Understanding P and N dynamics in manure-amended soil is essential for estimating the environmental impact of manure utilization in land applications. A laboratory incubation study was conducted to assess, (i) the effect of feeding a standard Australian commercial diet, and diets modified with phytase supplementation and reduced nonphytase phosphorus (NPP), on the concentrations of P and N (total ...

  • Grow to Order and Seed Collection

    Local provenance planting is important to help restore our natural habitats and retain the genetic integrity of plant populations and is strongly recommended for projects within or near environmentally sensitive areas. Forward planning is essential when undertaking local provenance seed collection as there are seasonal constraints such as seed maturation time, finding seed donor sites and gaining ...

  • Bioaccumulation and distribution of perfloroalkyl acids in seafood products from Bohai Bay, China

    Ten perfluoroalkyl acids (PFAAs) were measured in the seafood collected from Bohai Bay, China, in 2010. The summed concentrations of the PFAAs were in the ranges of ND–194 and 4.0 to 304 ng/g dry weight for invertebrates and fish, respectively. The levels of perflurooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA) in the seafood were lower than those from North America, the Mediterranean ...

  • Cover Crop and nitrogen effects on maize productivity in no-tillage systems of the Brazilian Cerrados

    Cover crops in direct seeding mulch-based cropping (DMC) systems can be an effective tool to optimize N management for crop production in the Brazilian cerrados. The objective of this study was to determine the effect of four cover crops on maize (Zea mays L.) grain yields in two fields that had been under DMC for 3 and 14 yr. We hypothesized that cover crops would optimize N supply to the maize ...

  • Cotton Planting date: yield, seedling survival, and plant growth

    New cultivars, changes in technology and production practices, and climate change may have altered the optimal planting time for cotton (Gossypium hirsutum L.) in the midsouthern United States. A field experiment was conducted from 2002 through 2005 on Gigger silt loam to define planting date (PD) effects on selected cotton cultivars. Six cultivars in 2002 (Deltapine DP555BR and Delta Pearl, ...

  • Maximizing Timothy forage yield and quality by balanced nitrogen, phosphorus, and sulfur fertilization

    A 3-yr (2005–2007) field experiment was conducted on a Gray Luvisol (Typic Cryoboralf) loam near Star City, SK, Canada, to determine the influence of single and combined annual applications of N, P, and S fertilizers on timothy (Phleum pratense L.) forage dry matter yield (DMY), quality [concentration of crude protein (CP), nitrate N, acid detergent fiber (ADF), neutral detergent fiber (NDF), ...

  • Micro, Small, and Medium Enterprises: Key Players in Climate Adaptation

  • Data Logger the size of a credit card

    Negligent handling of temperature sensitive goods can have fatal consequences. Of course it is advantageous to control temperatures, however temperature data loggers of the past were often bulky and unmanageable. Now there is a data logger which has been reduced to the size of a credit card. Goods are not always treated gently during transportation. Shipping businesses are increasingly under ...

DIA’s snow removal is ...

  • Optimum short-term futures hedge using stochastic linear programming

    Classical optimal hedge ratio concentrates on risk reduction and neglects strategic value maximisation. In this study, the authors use stochastic optimisation theories to formulate an optimal, short-term hedging scheme to mitigate risks while maximising portfolio value. Stochastic spot and futures price models are used to simulate prices. The periodic optimal hedge ratios are determined using the ...

  • Timber frame and post and beam construction

    Timber framing and "post-and-beam" construction are a unit strategies of building with heavy weight timbers instead of dimensional timber like 2"x4"s. Timber framing is sometimes additionally known as post and beams because as it is evident for its name that it is a way of using frame made of timber wood for construction because it acts as the main structure providing support to the ...


  • Recovery of photosynthesis and growth rate in green, blue–green, and diatom algae after exposure to atrazine

    We evaluated the recovery of photosynthesis and growth rate in green (Pseudokirchneriella subcapitata), blue‐green (Anabaena flos‐aquae), and diatom (Navicula pelliculosa) algae after pulsed exposure to atrazine. Subsequent to a grow‐up period of 24 to 72 h to establish requisite cell density for adequate signal strength to measure photosystem II (PSII) quantum yield, algae were exposed to a ...
