...CRITIQUE PAPER IN ChE 426N The research paper is entitled “Electricity generation from synthetic substrates and cheese whey using a two chamber microbial fuel cell”. The authors are Georgia Antonopoulou, Katerina Stamatelatou, Symeon Bebelis, and Gerasimos Lyberatos from the Department of Chemical Engineering in the University of Patras in Greece. The research paper is taken from pages 10 to 15 of the Biochemical Engineering Journal, Volume 50. In this study, the possibility of electricity generation from diluted cheese whey in a two-chamber mediator-less microbial fuel cell (MFC) was investigated. The research aims to generate electricity using glucose, lactose, and cheese whey wastewater as substrates. It also aims to compare the performance of a MFC using synthetic sugars, such as glucose and lactose, to that of the same MFC when using raw wastewater, such as cheese whey, as substrate. The title of the article is appropriate and clear in such a way that readers can grasp an idea of the research by just reading it. The abstract is specific and is a representative of the article, although it takes a second look to realize that the research would involve electricity generation from synthetic substrates such as glucose and fructose, and from cheese whey. The research problem is attention-grabbing and timely since there is recently an emerging interest focused on the energy recovery from wastes. Microbial fuel cell (MFC) is gaining promising interest in the research fraternity...

...Chemtrails There is something in the skies above us that cannot be easily explained. We see it almost every day, yet we take it for granted. Vast patterns of cloud like contrails cover every major metropolitan area in the world on a daily basis. They are referred to as ‘chemtrails’ and they stretch from horizon to horizon in either direction. Sometimes the patterns resemble a tic-tac-toe like grid and at other times form huge X shaped patterns. After being sprayed, the chemtrails slowly merge together to form a huge blanket of cloud cover. The particles that make up these artificial clouds can take as long as a day to fall to the ground. When they fall they resemble soap bubbles or an ashy snow like substance and when they settle they leave a sticky residue on everything they touch. We don’t know for certain what these chemtrails are comprised of or why they are being sprayed above us on a routine basis. Theories range from an attempt to stop global warming to government attempts to poison us for population control, but one thing we know for sure is that they do exist. Most people discover the reality of chemtrails by initially reading about it on the Internet and then going outside and looking up into the sky. They are shocked to realize that what they had been reading about and seeing in countless photographs is also taking place right over their heads. What some people had dismissed as mere "jet plane exhaust" are dismayed to realize that chemtrails are indeed the...

...CHAPTER ONE 1. INTRODUCTION 1.0 DEFINITION OF TRADITIONAL MEDICINE, HERBAL PREPARATION AND FINISHED HERBAL PRODUCTS The World Health Organization (WHO) defines traditional medicine as the sum total of knowledge, skills and practices based on the theories, beliefs and experiences indigenous to different cultures. Traditional medicine is used in the maintenance of health the prevention, diagnosis, improvement or treatment of physical and mental illness, whether explicable or not and is passed on from generation to generation. Herbal Preparations contain plant parts or plant material in the crude or processed state as active ingredients and may contain excipients. (WHO, 1996a; Busse, 1999). Combinations with chemically defined active substances or isolated constituents are not considered herbal preparations (Busse, 2000; GNDP, 2004). According to the European Medicine Evaluation Agency (EMEA), herbal preparations are medicinal products containing exclusively herbal drugs or herbal drug preparations as active substances (WHO, 1996b; Busse, 2000). Several chemical constituents with different pharmacological targets are involved in the therapeutic action of herbal preparations. This may be an advantage compared to single isolated compounds, especially when the underlying disease has a multifactorial etiology which is the case in many chronic illnesses. Herbal preparations may include comminuted or powdered plant material, extracts, tinctures, fatty or essential oils of...

...Research Proposal MSc Part 2 Sem 3 CERTIFICATE This is to certify that Mr. Akshay L. Shettigar has satisfactorily completed his proposal entitled “Biodegradation study of Triphenylmethane dye Crystal Violet by bacterium isolated from textile effluent.” for the year 2014-2015. Signature of the Project guide Signature of the Examiner (Prof. Mrs Radhika Birmole) Date and college Stamp Signature of the H.O.D. Proposal (i) Project Title: Biodegradation study of Triphenylmethane dye Crystal Violet by bacterium isolated from textile effluent. (ii) Introduction: Synthetic dyes are extensively used in textile dyeing, paper printing, colour photography, pharmaceutical, cosmetic and other industries [1]. Over ten thousand different dyes with an annual production of over 7x105 metric tons worldwide are commercially available [2]. 2% of dyes that are produced are discharged directly in aqueous effluent and 10% are subsequently lost during the textile coloration process [3]. Major classes of synthetic dyes include azo, triphenylmethane and anthraquinone dyes, some of them are known to be very toxic and mutagenic to living organism. With the increasing use of wide variety of dyes pollution by dye-waste water is becoming increasingly alarming. Colour removal, in particular, has recently become a major scientific interest. Although several...

Raaijmakers ∗ , Maria Vlami & Jorge T. de Souza Department of Plant Sciences, Laboratory of Phytopathology, Wageningen University, Binnenhaven 5, 6709 PG Wageningen, The Netherlands (∗ Author for correspondence) Abstract Interest in biological control of plant pathogens has been stimulated in recent years by trends in agriculture to-wards greater sustainability and public concern about the use of hazardous pesticides. There is now unequivocal evidence that antibiotics play a key role in the suppression of various soilborne plant pathogens by antagonistic microorganisms. The significance of antibiotics in biocontrol, and more generally in microbial interactions, often has been questioned because of the indirect nature of the supporting evidence and the perceived constraints to an-tibiotic production in rhizosphere environments. Reporter gene systems and bio-analytical techniques have clearly demonstrated that antibiotics are produced in the spermosphere and rhizosphere of a variety of host plants. Several abiotic factors such as oxygen, temperature, specific carbon and nitrogen sources, and microelements have been identified to influence antibiotic production by bacteria biocontrol agents. Among the biotic factors that may play a determinative role in antibiotic production are the plant host, the...

...Preface A well-developed knowledge of clinical microbiology is critical for the practicing physician in any medical field. Bacteria, viruses, and protozoans have no respect for the distinction between ophthalmology, pediatrics, trauma surgery, or geriatric medicine. As a physician you will be faced daily with the concepts of microbial disease and antimicrobial therapy. Microbiology is one of the few courses where much of the "minutia" is regularly used by the practicing physician. This book attempts to facilitate the learning of microbiology by presenting the information in a clear and entertaining manner brimming with memory aids. Our approach has been to: 4) Create a conceptual, organized approach to the organisms studied so the student relies less on memory and more on logical pathophysiology. The text has been updated to include current information on rapidly developing topics, such as HIV and AIDS (vaccine efforts and all the new anti-HIV medications), Ebola virus, Hantavirus, E. coli outbreaks, Mad Cow Disease, and brand-new antimicrobial antibiotics. The mnemonics and cartoons in this book do not intend disrespect for any particular patient population or racial or ethnic group but are solely presented as memory devices to assist in the learning of a complex and important medical subject. We welcome suggestions for future editions. 1) Write in a conversational style for rapid assimilation. 2) Include numerous figures serving as "visual memory tools" and summary charts...
