There is limited information on the sensitivity of dry bean to dimethenamid-p, saflufenacil and a preformulated mixture of dimethenamid-p/saflufenacil. Field trials were conducted at Exeter and Ridgetown, ON, Canada in 2012 and 2013 to evaluate the tolerance of four market classes of dry bean to dimethenamid-p, saflufenacil and dimethenamid-p/saflufenacil applied preemergence (PRE) at the 1X and 2X manufacturer’s recommended rate in soybean. Dimethenamid-p, saflufenacil and dimethenamid-p/saflufenacil applied PRE caused 0% - 2%, 20% - 31% and 34% - 45% injury in dry bean, respectively. Dimethenamid-p (220 and 440 g ai ha-1) caused no adverse effect on plant stand, shoot dry weight, height and yield of black, white, adzuki and kidney bean. Saflufenacil (25 and 50 g ai ha-1) or dimethenamid-p/saflufenacil (245 and 490 g ai ha-1) reduced plant stand 53% - 70%, shoot dry weight 61% - 81%, height 26% - 48% and yield 40% - 61% of black and white bean. However, saflufenacil applied alone or in combination with dimethenamid-p at the 1X or 2X rates caused no adverse effect on plant stand, shoot dry weight, height and yield of adzuki and kidney bean except with dimethenamid-p/saflufenacil at the 2X rate which reduced plant stand 38% in kidney bean, shoot dry weight 46% in adzuki bean and 42% in kidney bean, and yield 29% in kidney bean. Based on these results, saflufenacil and dimethenamid-p/saflufenacil applied PRE at the proposed rate of 25 and 245 g ai ha-1, respectively does have an adequate margin of crop safety for weed management in black and white bean. Further research is needed to ascertain the margin of crop safety in kidney and adzuki bean.

A Comparison of Methods Used to Determine the Oleic/Linoleic Acid Ratio in Cultivated Peanut (Arachis hypogaea L.)

Cultivated peanut ( Arachis hypogaea L.) is an important oil and food crop. It is also a cheap source of protein, a good source of essential vitamins and minerals, and a component of many food products. The fatty acid composition of peanuts has become increasingly important with the realization that oleic acid content significantly affects the development of rancidity. And oil content of peanuts significantly affects flavor and shelf-life. Early generation screening of breeding lines for high oleic acid content greatly increases the efficiency of developing new peanut varieties. The objective of this study was to compare the accuracy of methods used to classify individual peanut seed as high oleic or not high oleic. Three hundred and seventy-four (374) seeds, spanning twenty-three (23) genotypes varying in oil composition (i.e. high oleic (H) or normal/not high oleic (NH) inclusive of all four peanut market-types (runner, Spanish, Valencia and Virginia), were individually tested ...

Location Optimization of a Coal Power Plant to Balance Costs against Plant’s Emission Exposure

Fuel and its delivery cost comprise the biggest expense in coal power plant operations. Delivery of electricity from generation to consumers requires investment in power lines and transmission grids. Placing a coal power plant or multiple power plants near dense population centers can lower transmission costs. If a coalmine is nearby, transportation costs can also be reduced. However, emissions from coal plants play a key role in worsening health crises in many countries. And coal upon combustion produces CO 2 , SO 2 , NO x , CO, Metallic and Particle Matter (PM10 & PM2.5). The presence of these chemical compounds in the atmosphere in close vicinity to humans, livestock, and agriculture carries detrimental health consequences. The goal of the research was to develop a methodology to minimize the public’s exposure to harmful emissions from coal power plants while maintaining minimal operational costs related to electric distribution losses and coal logistics. The objective was...

Evaluation of the Safety and Efficacy of Continuous Use of a Home-Use High-Frequency Facial Treatment Appliance

At present, many home-use beauty devices are available in the market. In particular, many products developed for facial treatment use light, e.g., a flash lamp or a light-emitting diode (LED). In this study, the safety of 4 weeks’ continuous use of NEWA TM , a high-frequency facial treatment appliance, every alternate day at home was verified, and its efficacy was evaluated in Japanese individuals with healthy skin aged 30 years or older who complained of sagging of the facial skin.  Transepidermal water loss (TEWL), melanin levels, erythema levels, sebum secretion levels, skin color changes and wrinkle improvement in the facial skin were measured before the appliance began to be used (study baseline), at 2 and 4 weeks after it had begun to be used, and at 2 weeks after completion of the 4-week treatment period (6 weeks from the study baseline). In addition, data obtained by subjective evaluation by the subjects themselves on a visual analog scale (VAS) were also analyzed. Fur...
