Manganese deficiency, Tomato Iron deficiency ... - Pure Hydroponics

pH Management of Hydroponics Solutions A question often asked is what is the best pH for a particular crop nutrient solution. The answers given in many texts, and often by advisers to growers, are frequently based on misunderstood information. Many refer to the availability of nutrients to plants at different pHʼs based on research by Troug (1946) [Proc. Soil Sci. Soc. Am., 11:305-308] even using graphic illustrations of his findings in one form or another, generally showing a bar graph with wide portions in the pH area where the element is most widely available to the plant. I have seen similar representations said to show the availability of trace elements in a hydroponics solution. This graphic representation of availability of trace, and sometimes the major elements, only applies to plants being grown in mineral (clay based) soils. It is not relevant to hydroponics solutions.As plants use nutrients their roots release bicarbonate that raises the pH of nutrient solutions. By the early 1990ʼs I had observed that the published and advised pH at which crops were grown did not correspond to my observations. At the time phosphoric acid was being used to routinely acidify hydroponics solutions and was causing imbalances in nutrient solutions and blockages due to precipitates. It made sense to replace the phosphoric acid entirely with nitric acid which could, by monitoring pH, be added at a rate related to plant use replacing Nitrogen (N) used in growth periods and so maintain a better balanced solution free of unwanted precipitates.

IMPORTANT TIPS FOR MEAL SELECTION  Aim for AT LEAST 60 GRAMS of protein per day : Example (6 oz of lean meat and 16oz of low fat dairy per day)  Wean off protein supplement when you reach your protein goal through your meals.  Eat protein foods first  After protein foods eat vegetables and fruit.  Eat only cooked vegetables and avoid high fiber vegetables.  Add foods slowly and one at a time to test tolerance.  Stop eating or drinking when full, overfilling may stretch the stomach pouch and hinder weight loss. FOODS TO AVOID  Soft breads, doughnuts, pastries. These may form a dough ball and block the stomach outlet.  Salads or other raw vegetables  Sugar and sweets (table sugar, cakes, cookies, pies, pastries)  High fat meat ( bacon, sausage, luncheon meats)  Steak, roast beef, pork, lamb, veal, venison.  High fat foods (butter, oil regular salad dressing, mayonnaise, sour cream, cream cheese, whole milk, cheese, ice cream, cake, cookies, pies)  Fibrous vegetables ( broccoli, cauliflower, brussel sprouts, corn, cabbage, salad greens, asparagus)  Fresh fruit except bananas  Rice and Pasta  Nuts, seeds, coconut, raisins and popcorn, dried fruit...

Adjustable Speed Drives As Applied To Centrifugal Pumps

Adjustable Speed Drives As Applied To Centrifugal Pumps Application Solution Foreword This article is a revised edition of the original D-7108 application waste energy, and generally cause the pump to operate at note as written by Dennis P. Connors, John D. Robechek, and reduced efficiencies. Dennis A. Jarc. The overall content and principles of this 1982 publication are still very much valid and relevant today. The significant changes that have occurred since this article was originally published is in AC technology. The dominant method of AC control is by PWM inverters, particularly with the advent of the high speed Insulated Gate Bipolar Transistors (IGBTs). This will be the only drives technology to be considered in this revisited analysis. Adjustable speed drives (ASDs) can achieve reduced flow by providing adjustable speed pump operation. This results in reduced system pressure and operation near the pump's Best Efficiency Point (BEP). In addition, maintenance costs might be reduced. This paper will discuss the energy savings potential of AC ASDs followed by a brief description of the operation and relative benefits of PWM AC drives.

Reliability Analysis of Centrifugal Pumps System Justifies ... - Abb

Over the past several years, reliability has become an ever-increasingly important topic and component in the organizational continuous improvement tool box. Higher plant reliability reduces process and equipment failures costs as failure disruption decreases production output which in turn limits gross margin. Additionally, equipment failures also increase the probability of having a catastrophic environmental accident and the potential for increasing safety related accidents. The strong competitive environment between companies to secure business and the current world financial crisis are forcing organizations to explore ways to reduce operating costs. A popular approach to reduce operating costs is to reduce expenditures on equipment maintenance. While results can be obtained by reducing investments in equipment, this approach is very short sighted. It is not unusual that deferred investments will re-surface and cost 2 to 5 times more than if addressed in the early stages of failure development. The purpose of this paper is to objectively demonstrate that an approach focused on reliability, availability and maintainability prediction will help to detect pieces, equipments and systems that require improvements helping to maintenance managers to make the right decision analyzing a centrifugal pump system in a gas plant.

2014 Sierra Denali Pairs High-Tech Luxury and Capability - GMC.com

2014 Sierra Denali Pairs High-Tech Luxury and Capability Available 6.2L EcoTec3 V-8 will be most powerful pickup truck engine on the market DETROIT – An all-new 2014 Sierra 1500 Denali full-size pickup arrives this fall with an available 6.2L EcoTec3 V-8 that will produce an estimated 420 horsepower and 450 lb-ft of torque, the most power and torque of any light duty truck engine. Final SAE-rated power and torque numbers will be available later this year. Now entering its third generation, the Sierra Denali is the most luxurious and technologically advanced GMC half-ton pickup. Sierra’s 6.2L V-8 will also be available for Sierra SLT models this fall. With this engine, the Sierra is expected to have a class-leading maximum trailering capacity of 12,000 pounds. Like every 2014 Sierra, it offers more power and higher expected efficiency than its predecessor thanks to a trio of technologies including direct injection, active fuel management and variable valve timing. Design cues for the 2014 Sierra Denali follow the formula that attracted two-in-10 GMC buyers to Denali vehicles last year. On the exterior, the truck has a signature Denali chrome grille, unique 20-inch chrome wheels, unique interior decorative trim, a polished stainless steel exhaust outlet and body-color front and rear bumpers. Denali-specific interior details include script on the bright door sills and embossed into the front seats and real aluminum trim. Sierra Denali’s high-tech interior also features an exclusive eight-inch Customizable Driver Display that can show relevant settings, audio and navigation information in the instrument panel. Sierra Denali’s standard eight-inch Color Touch navigation radio with Intellilink, located above the center console, serves as the main hub for Bluetooth-connected phones and portable devices connected through five standard USB ports.
