Both plants and some plant pathogens can produce IAA to modulate plant growth. Although the genes and biochemical reactions for auxin biosynthesis in some plant pathogens are well understood, elucidation of the mechanisms by which plants produce auxin has proven to be difficult. So far, no single complete pathway of de novo auxin biosynthesis in plants has been firmly established. However, recent studies have led to the discoveries of several genes in tryptophan-dependent auxin biosynthesis pathways. Recent findings have also determined that local auxin biosynthesis plays essential roles in many developmental...

...RESEARCH PROPOSAL A STUDY ON THE IMPACT AND ADDICTION BY USING THE TECH-GADGETS BY THE STUDENTS TO THEIR LEARNING PROCESS AT UNIVERSITY COLLEGE SHAHPUTRA: A STUDY ON COLLEGE STUDENTS CHAPTER I Introduction 1.0 Background of the Study The term technology comes from the Greek word “techne”, which means the art or skill used in order to solve a problem, improve a pre-existing solution to a problem, achieve a goal, handle an applied input/output relation or perform a specific function; technology is the making, modification, usage and knowledge of tools, machines, techniques and method of organisation (Liddel, Scott, Jones & McKenzie, 1940). That means, it can refer to the collection of tools, including machinery, modification, arrangements and procedures. Over the last 200 years there has been a significant change in the term technology. In the 20th century i.e. during the industrial revolution the term has gained its popularity worldwide (Cradock & Baldwin, 1833). Technology is the energy that acts as the driving force to drive or to run our lives. It is nothing but the results of the innovations and creativity of human beings. It converts the natural resources into consumer goods which are used by the society and human beings. It has brought the automation level into such a height that human effort and his time has been saved to a great extent. Due to this, the access to information has now become easier and the distant locations are getting closer. IT and communication...

...Maria Vasilenko 223901 Feasibility of using biosensors for heavy metal detection in complex matrices such as bio-slurries. Master of Science Thesis Examiners: Professor Matti Karp Professor Raghida Lepistö Examiner and topic approved in The Science and Bioengineering Department Council meeting on 7.11.2012 Abstract TAMPERE UNIVERSITY OF TECHNOLOGY Master‟s Degree Programme in Science and Bioengineering Vasilenko Maria: Feasibility of using biosensors for heavy metal detection in complex matrices such as bio-slurries. Seminar paper, 97 pages November 2012 Major: Biotechnology Examiners: Matti Karp, Raghida Lepisto Keywords: environmental pollution, heavy metals, biosensors, slurries The quality of bioslurries that are used in industrial production and agriculture need to be watched very closely to avoid spreading of contaminants on area and poisoning of humans and animals. Because heavy metals are very stable and toxic in many chemical compositions, their amount should be estimated very thoroughly. A new approach that involved biosensors was tested in this study. Because the slurries are complex non-unified matrices which composed of two phases – solid and liquid, the cell behavior can varies a lot from the one that explained in water and so the estimation of ion concentration can be not reliable. It was shown that the cell actually behave different in the slurries. Normally the dissolved compounds suppress the biosensor activity and, in the same time, the ions in the...

...ENERGY POLICY AND CONSERVATION IN NIGERIA: IMPLICATIONS FOR RURAL DEVELOPMENT BY O.ADEGBUYI AND O.O. FASORANTI (PhD) ABSTRACT To impact visible advances in rural communities in Nigeria for achieving meaningful economic goals, the effective policy of energy usage as a vessel for the acquisition and utilization of required technologies to develop and recover the present depreciating national economy associated with poor food production must be focussed strategically. The socio-economic growth of any developing nation is generally a function of the level of maintenance of her energy demand supply balance and sustainable food production. Nigeria may attain the potential status of an industrialised nation by the year 2010 if all available manpower and other natural resources are well utilized before then to effectively harness her potentials of cheaper alternative energy technologies for long term economic and rural developmental goals. This paper presents the nation’s requirement of a well- articulated energy policy and urgent implementation strategies emphasizing on appropriate energy conservation concepts to promote optimal utilization of existing energy resources in her rural areas. It is therefore suggested that the development of available alternative energy resources be encouraged for integrated rural growth, sufficient food production and small scale industrialization thereby alleviating poverty in the rural communities of the...

...1 EFFICIENT MARKETS HYPOTHESIS Andrew W. Lo To appear in L. Blume and S. Durlauf, The New Palgrave: A Dictionary of Economics, Second Edition, 2007. New York: Palgrave McMillan. The efficient markets hypothesis (EMH) maintains that market prices fully reflect all available information. Developed independently by Paul A. Samuelson and Eugene F. Fama in the 1960s, this idea has been applied extensively to theoretical models and empirical studies of financial securities prices, generating considerable controversy as well as fundamental insights into the price-discovery process. The most enduring critique comes from psychologists and behavioural economists who argue that the EMH is based on counterfactual assumptions regarding human behaviour, that is, rationality. Recent advances in evolutionary psychology and the cognitive neurosciences may be able to reconcile the EMH with behavioural anomalies. There is an old joke, widely told among economists, about an economist strolling down the street with a companion. They come upon a $100 bill lying on the ground, and as the companion reaches down to pick it up, the economist says, ‘Don’t bother – if it were a genuine $100 bill, someone would have already picked it up’. This humorous example of economic logic gone awry is a fairly accurate rendition of the efficient markets hypothesis (EMH), one of the most hotly contested propositions in all the social sciences. It is disarmingly simple to state, has far-reaching consequences...

...Story Of Stuff, Referenced and Annotated Script By Annie Leonard Do you have one of these? I got a little obsessed with mine, in fact I got a little obsessed with all my stuff. Have you ever wondered where all the stuff we buy comes from and where it goes when we throw it out.? I couldn’t stop wondering about that. So I looked it up. And what the text books said is that our stuff simply moves along these stages: extraction to production to distribution to consumption to disposal. All together, it’s called the materials economy. Well, I looked into it a little bit more. In fact, I spent 10 years traveling the world tracking where our stuff comes from and where it goes.1 And you know what I found out? That is not the whole story. There’s a lot missing from this explanation. For one thing, this system looks like it’s fine. No problem. But the truth is it’s a system in crisis. And the reason it is in crisis is that it is a linear system and we live on a finite planet and you can not run a linear system on a finite planet indefinitely.2 Every step along the way, this system is interacting with the real world. In real life it’s not happening on a blank white page. It’s interacting with societies, cultures, economies, the environment. And all along the way, it’s bumping up against limits. Limits we don’t see here because the diagram is incomplete. So let’s go back through, let’s fill in some of the blanks and see what’s missing. Well, one of the most important things that is missing...

...MEAT AS HEALTHY SMOOTHIE Jo V. Ambat Annie Grace A. Bustamante Nico Braselle Casaña Raymond M. de Taza Manche P. Pere A research study presented to the faculty of Home Economics, Vocational and Technical, Education Department, College of Education, Cavite State University, Indang, Cavite in partial fulfilment of the requirements in HRML 24- Research I. Prepared under the supervision of Dr. Editha G. Reyes 1. INTRODUCTION The avocado is colloquially known as the Alligator Pear, reflecting its shape and the leather-like appearance of its skin. Avocado is derived from the Aztec word "ahuacatl". Avocados are the fruit from Persea americana, a tall evergreen tree that can grow up to 65 feet in height. Avocados vary in weight from 8 ounces to 3 pounds depending upon the variety. There are dozens of varieties of avocadoes. The rich and creamy Hass variety is the most popular type of avocado in the United States, and 95% of all avocados grown in the United States are produced in California, original home of the Hass variety. They are generally available throughout the year, they are the most abundant and at their best during the spring and summer in California and in October in Florida. While avocados are technically fruits, we have categorized them here as vegetables since this is how they are usually considered from a culinary perspective. Avocados can make a great base for a high-energy smoothie that will satisfy you and keep you going for hours. The scientific name...

...Risk in Housing Markets: An Equilibrium Approach⇤ Aurel Hizmo† NYU Stern January 30, 2012 Abstract Homeowners are overexposed to city-specific house price risk and income risks, which may be very di cult to insure against using standard financial instruments. This paper develops a micro-founded equilibrium model that transparently shows how this local uninsurable risk a↵ects individual location decisions and portfolio choices, and ultimately how it a↵ects prices in equilibrium. I estimate a version of this model using house price and wage data and provide estimates for risk premia for di↵erent cities, which imply that homes are on average about $20000 cheaper than they would be if owners were risk-neutral. This estimate is over $100000 for volatile coastal cities. Next, I simulate the model to study the e↵ects of financial innovation on equilibrium outcomes. Creating assets that hedge city-specific risks increases house prices by about 20% and productivity by about 10%. The average willingness to pay for completing the market per homeowner is between $10000 and $20000. Welfare gains come both from better risk-sharing and from more e cient sorting of households across cities. ⇤ I am deeply grateful to Patrick Bayer, Andrew Patton, and Peter Arcidiacono for their encouragement and support. I also thank Robert McMillan, Tim Bollerslev, Vish Viswanathan, Chris Timmins, Jimmy Roberts and the seminar participants at Duke Finance, the ERID Conference at Duke, Fed Board, NYU Stern...
