DESCRIPTION:BIORESOURCE ENGINEERING SENIOR SEMINAR\n\nItem 1: Peter Adewale
 \nMethanol and Waste Oils for Biodiesel Production\n\nSkyrocketing crude o
 il prices\, global shortage of fossil fuels and\nincreased environmental c
 oncerns have resulted in the rapid growth\nin biodiesel production. Likewi
 se\, the leverage on global food\nsecurity of biofuels production has been
  a great concern.\nAlternative oil source has been an important way to sus
 tain\nbiodiesel production without interference with global food\nsecurity
 . This research study is aimed at enhancing biodiesel\nproduction from was
 te oils. Hydrodynamics of methanol-waste oils in\na stirred vessel would b
 e modeled to investigate the miscibility of\nthe two partially immiscible 
 liquids. Different impeller types\,\nimpeller position on the stirrer shaf
 t and more than one impeller\non the stirrer shaft would be used to model 
 the drop size and drop\nsize distribution of methanol into waste oils for 
 the production of\nbiodiesel.\n\nPeter Adewale is a PhD student in the Dep
 artment of Bioresource\nEngineering\, 91Ë¿¹ÏÊÓƵ under the supervis
 ion of Dr. M.O.\nNgadi. He has a B. Eng in Agricultural Engineering from t
 he\nUniversity of Ilorin and M.Sc in Agricultural and Environmental\nEngin
 eering from the University of Ibadan\, both in Nigeria. Peter\ncomes from 
 south- west region of Nigerian. Currently working on\nhydrodynamics of met
 hanol –waste oils for the production of\nbiodiesel in Dr. Ngadi’s laborato
 ry\n\n\nItem 2: Justina Amissah\nAntioxidants and Oxidants: A Necessary Ba
 lance\n\nResearch on the effects of antioxidants has revealed a strong\nre
 lationship between the diets of people and the development of\nchronic dis
 eases like coronary heart disease\, diabetes and\natherosclerosis. A diet 
 rich in vegetables and fruits is suggested\nto minimize the risk of chroni
 c diseases possibly due to the\npresence of antioxidant compounds. However
 \, antioxidants may be\nregarded as a potentially dangerous tool when they
  exceed a certain\nlimit and rather promote oxidation which may result in 
 health\nproblems in the long run. Thus the key to the effectiveness of\nan
 tioxidants within the body in minimizing the negative effect of\noxidative
  stress is suggested to be due to a balance between\nantioxidants and oxid
 ants.\n\nJustina Amissah is an MSc Thesis student in the Bioresource\nEngi
 neering Department and is supervised by Dr. Shiv Prasher and\nDr. Benjamin
  Simpson (Food Science Department). She completed her\nundergrad studies a
 t the Kwame Nkrumah University of Science and\nTechnology where she studie
 d Biochemistry. She is currently working\non bioactive peptides from Agric
 ultural wastes.\n\n\nItem 3: Michel Duteau\nPhosphorus Removal in a Constr
 ucted Wetland\n\nConstructed wetlands can be used to remove pollutants con
 veyed by\nagricultural sub-surface drainage wastewaters before they reach
 \nnatural ecosystems\, where they could contribute to the acceleration\nof
  freshwater ecosystems eutrophication. A study was conducted to\ndetermine
  if a supplementary phosphorus treatment was needed\, when\nusing a sub-su
 rface vertical upflow constructed wetland made up of\na coarse sandy loam 
 and planted with willows (salix myabeanna).\nPreliminary results show that
  the outlet concentrations can be\nbrought down to the 0.03 mgTPL-1 eutrop
 hication threshold. We will\ndiscuss the fate of Phosphorus within a const
 ructed wetland.\n\nMichel is a freshwater ecosystems biologist\, specializ
 ed in\nrestoration in the agriculture sector. He is currently leading a\nM
 Sc research effort on Constructed wetlands for the treatment of\nagricultu
 ral sub-surface drainage wastewaters\, under the\nsupervision of Drs Grant
  Clark & Shiv O. Prasher.\n\n\nItem 4: Julie Gagné\nRecirculating Aquacult
 ure Systems\n\nLand-based\, closed Recirculating Aquaculture Systems (RAS)
  combine\nthe culture of fish with soilless hydroponic plant production\,
 \nefficiently recycling fish wastewater as plant nutrient solution.\nWhere
  in traditional fish aquaculture wastewater treatment was an\neconomic bur
 den on producers\, in aquaponic polycultures nutrient\nremoval by plants g
 enerates additional revenue from produce sales\,\nproviding 67% of annual 
 returns in one rainbow trout\, lettuce and\nbasil RAS system. This is a pr
 ime example of the type of\n‘closed-loop’ ecosystem approach which will in
 creasingly become\nparamount as global populations boom within a flailing 
 and resource\nlimited natural world. Quite an efficient waste treatment sc
 heme\,\nand with global fish stocks collapsing as ‘sushi’ lovers become\nl
 egion\, it could offer an alternative\, sustainable\, local source of\nfis
 h to quell those appetites and give Oceans a break.  \n \n\nMontreal born 
 and raised\, Julie obtained her B.Sc Ag.Env.Sc. in\nMicrobiology here at M
 ac\, before working on a fascinating\nagricultural soil microbiology resea
 rch project in Sorel\, Qc\, for a\nfew years. After a subsequent  2-year G
 LP stint closer to home\nworking in Pharmacogenomics for Genome Quebec\, s
 he has returned to\nacademia to re-focus her career on environmental topic
 s. Julie is\nnow conducting her M.Sc. thesis degree under the supervision 
 of Dr.\nMark Lefsrud of the Biomass Lab\, studying the effects of waveleng
 th\non plant growth.\n\nItem 5: Shrikalaa Kannan\nMicrobial Safety of Eggs
 \n\nEggs are one of nature’s most nutritious food but are safe only\nwhen 
 they are cooked properly. But most people love to eat raw egg\nrecipes lik
 e mayonnaise\, hollandaise sauce\, egg nog\, Caesar salad\nand many more. 
 Several Salmonellosis outbreaks in the recent past\nhave been traced back 
 to consumption of contaminated eggs. Eggs\nserve as good nutrition source 
 for the growth of microbes too.\nDespite the presence of egg’s own defense
  mechanisms\, certain\nmicrobes like Salmonella enteritidis[SE] have manag
 ed to render the\negg’s defense ineffective. This presentation is to bring
  to light\nthe microbial profile of eggs\, routes of entry and the FDA\nre
 commendations for producers and consumers to make eggs safer for\nhuman co
 nsumption.\nShrikalaa Kannan was born in India where she received her B. T
 ech\nBiotechnology from the PSG College of Technology in Tamil Nadu.\nShri
 kalaa is currently in her first year as an MSc candidate in the\nBioresour
 ce Engineering Department under the supervision of Dr.\nRaghavan.\n
