After the initial stages of water treatment where organic and inorganic solids are mechanically removed from wastewater, water is further treated through secondary and tertiary treatment processes. Since the effluent from primary treatment still contains extremely fine organic and inorganic solids, secondary treatment of water aims to remove these solids. “Secondary treatment consists of unique biological systems designed to remove BOD, suspended solids and some dissolved solids through a biological conversion of these materials to a settleable form. The biomass is then separated from the product water (secondary effluent) in a secondary or final clarifier. Secondary treatment systems typically remove 80-95% of suspended solids and BOD” (Ciy of San Jose). This process is carried out through the addition of oxygen into the water as the system uses oxygen tanks, secondary clarifiers, and return sludge pumping stations. Secondary treatment speeds up the natural process and microorganisms use pollutants as a food source and thus eliminate a majority from the water (Schiff). Secondary treatment typically utilizes biological treatment processes, in which microorganisms convert nonsettleable solids to settleable solids. Sedimentation typically follows, allowing the settleable solids to settle out. Three options include:
1. Activated Sludge- The most common option uses microorganisms in the treatment process to break down organic material with aeration and agitation, then allows solids to settle out.
Bacteria-containing “activated sludge” is continually re-circulated back to the aeration basin to increase the rate of organic decomposition.
2. Trickling Filters- These are beds of coarse media (often stones or...

Negoation

...Managing Negotiation Introduction From reaching an agreement with a large client to bargaining for a higher starting salary, the ability to negotiate effectively is a critical component of success in business. One fundamental aspect of a negotiation is if it will be approached as distributive bargaining or as an integrative negotiation. Distributive bargaining is a competitive, zero-sum negotiation in which there are a limited amount of resources available, while integrative negotiation takes place when “the parties’ goals are not seen as mutually exclusive and in which the focus is on making it possible for both sides to achieve their objectives” (Nelson and Quick 2009). For example, a dispute over land would necessitate distributive bargaining, whereas a partnership between two firms to buy and sell a product could be made through integrative negotiation. The process of two or more parties reaching a joint decision is influenced by a variety of factors. In analyzing business negotiation, we will first give an overview of past scholarly research on the topic, and then explore more current mental models of negotiation. We will also examine the possible hurdles to reaching agreements posed by cross cultural differences, particularly between American and Chinese business people. Finally, we discuss the relative importance of BATNAs (Best Alternative to Negotiated Agreement) and contributions in the bargaining process. History of Negotiation Research In the......

Ingridenents of the Food System

...INGREDIENTS OF THE FOOD SYSTEM BACKGROUND READING "How we eat determines, to a considerable extent, how the world is used."1 –Wendell Berry, author and farmer Food holds many meanings and serves many roles. At its most basic level, it is a source of nourishment, without which we would cease to function. On a global scale, nations depend on food for political stability.2 Among the one in six people worldwide who lack adequate access to food,3 it may be viewed as a rare and precious commodity. Others who enjoy access to an abundant food supply may take it for granted; in many parts of the world, consumers and food industries discard it in great quantities.4 Beyond its biological roles, food has deep social meaning; it can serve as a mark of culture, values or taste, a gathering point among communities or an opportunity to reinforce relationships.5,6 On a personal level, food and emotion are closely tied.7 Food may provide temporary relief from anxiety, depression, loneliness and boredom.7 Feelings of joy and other positive emotions may inspire healthier, more pleasurable eating experiences.7 These examples illustrate just a few of the ways that food is an integral part of human lives. We all experience food, if for no other reason than because we all consume it. Our relationship with food, however, extends far beyond the act of eating. Food takes a complex journey from its origins on farm fields, ranches, rivers, oceans and other sources to consumers’ plates. Along the way...

Left Atrial Function: Physiology, Assessment, and Clinical Implications

...European Journal of Echocardiography (2011) 12, 421–430 doi:10.1093/ejechocard/jeq175 REVIEW Left atrial function: physiology, assessment, and clinical implications Gustavo G. Blume 1, Christopher J. Mcleod 1, Marion E. Barnes 2, James B. Seward 1, Patricia A. Pellikka 1, Paul M. Bastiansen 1, and Teresa S.M. Tsang 2* 1 Division of Cardiovascular Diseases and Internal Medicine, Mayo Clinic, Rochester, MN, USA; and 2Division of Cardiology, University of British Columbia, 2775 Laurel Street, Vancouver, BC, Canada Online publish-ahead-of-print 12 May 2011 The interest in the left atrium (LA) has resurged over the recent years. In the early 1980s, multiple studies were conducted to determine the normal values of LA size. Over the past decade, LA size as an imaging biomarker has been consistently shown to be a powerful predictor of outcomes, including major public health problems such as atrial fibrillation, heart failure, stroke, and death. More recently, functional assessment of the LA has been shown to be, at least as, if not more robust, a marker of cardiovascular outcomes. Current available data suggest that the combined evaluation of LA size and LA function will augment prognostication. The aim of this review is to provide a critical appraisal of current echocardiographic techniques for the assessment of LA function and the implications of such assessment for prediction and disease prevention. ------------------------------------------------------------------...

...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...
