Climate change is fundamentally a risk management problem. Whether or not you agree with the 97 percent expert consensus on human-caused global warming, there is an undeniable risk that the consensus is correct and that we're causing dangerously rapid climate change.
Nutrient Solution Formulation for Hydroponic (Perlite, Rockwool, NFT) Tomatoes in Florida1 George J. Hochmuth and Robert C. Hochmuth2 Plants require 16 elements for growth and these nutrients can be supplied from air, water, and fertilizers. The 16 elements are carbon (C), hydrogen (H), oxygen (O), phosphorus (P), potassium (K), nitrogen (N), sulfur (S), calcium (Ca), iron (Fe), magnesium (Mg), boron (B), manganese (Mn), copper (Cu), zinc (Zn), molybdenum (Mo), and chlorine (Cl). The key to successful management of a fertilizer program is to ensure adequate concentrations of all nutrients throughout the life cycle of the crop. Inadequate or excessive amounts of any nutrient result in poor crop performance. Excessive amounts can be especially troublesome since they can damage the crop, waste money and fertilizer resources, and pollute the environment when fertilizer is released during flushing of the nutrient delivery system. problem comes early in the season when plants become too vegetative (bullish) from too much N. The bullish growth distorts the leaves and stems, causing cracks and grooves in the stems. These openings are excellent entry ports for decay-causing organisms such as soft rot. Bullish plants usually produce misshapen fruits often with significant amounts of blossom-end rot and cat-facing. Keeping the N level low (60 to 70 parts per million) early in the season helps eliminate bullishness. For Florida greenhouse vegetable producers, management focuses on all nutrients except for C, H, and O. The latter three elements are usually supplied in adequate amounts from air and water. Growers in northern climates, where greenhouses are not ventilated in the winter, see benefits from additions of C from carbon dioxide (CO2). Increased yields in Florida from additions of CO2 are unlikely due to the need for frequent ventilation. Nutrient management programs should begin with an understanding of the nutrient solution concentrations in parts per million (ppm) for the various nutrients required by tomato plants. By managing the concentrations of individual nutrients, growers can control the growth and yield of the crop. Table 1 presents the fertilizer recommendations for tomatoes for the various growth stages during the season in Florida. These recommendations are applicable to all types of production systems (perlite, rockwool, and NFT) in which healthy roots are maintained, and are a suitable base when determining a nutrient solution plan for cucumbers and peppers. However, cucumbers will need more N early in the season than tomato.
Reading and understanding centrifugal pump curves is key to proper pump selection, and to their reliable and efficient operation. This Tech Brief examines how pump curves can provide data about a pump’s ability to produce flow against certain head, shows how to read a typical centrifugal pump curve, and provides information about pump efficiency and brake horsepower. Pumps are the workhorses of any drinking water distribution or wastewater collection system. They operate 24 hours a day, 365 days a year getting water to homes and business, and removing wastewater from them. A correctly sized pump will work efficiently for many years, saving a system money and energy. An incorrectly sized pump can fail if it’s too small or result in unnecessary expense if it’s too big. Pump curves provide a way to see the correct size a pump should be for specific conditions. Pump Terminology Before discussing specific details, it helps to understand typical terms associated with pump curves: Impeller—the moving element in a pump that drives the liquid. Volute—the spiral-shaped casing surrounding a pump impeller that collects the liquid discharged by the impeller. Head—a measure of the pressure or force exerted by water expressed in feet. Centrifugal pump curves show pressure as head, which is the equivalent height of water with specific gravity = 1. Static Head—the vertical height difference from the surface of a water source to the centerline of the impeller. The vertical height difference from the centerline of the impeller to the discharge point is called discharge static head, while the vertical height difference from the surface of the water source to the discharge point is known as total static head. Total Head / Total Dynamic Head—the total height difference (total static head) plus friction losses and demand pressure from nozzles etc. (total discharge head) = total dynamic head. Capacity/Flow—the rate of liquid flow that can be carried, typically measured in gallons per minute (gpm). Net Positive Suction Head—how much suction lift a pump can achieve by creating a partial vacuum. Atmospheric pressure then pushes liquid into pump. A method of calculating if the pump will work or not. Cavitation—cavities or voids in liquid. Bubbles take up space leading to a drop in pump capacity. Collapsing bubbles can damage the impeller and volute, making cavitation a problem for both the pump and the mechanical seal. Specific Gravity—the weight of liquid in comparison to water at approximately 20° C (SG = 1). Specific Speed—a measure of the function of pump flow, head, and efficiency. Vapor Pressure—the force exerted by the gas released by a liquid in a closed space. If the vapor pressure of a liquid is greater than the surrounding air pressure, the liquid will boil. Viscosity—a measure of a liquid’s resistance to flow (i.e., how thick it is). The viscosity determines the type of pump used, how fast it can run, and with gear pumps, the internal clearances required. Friction Loss—the amount of pressure / head required to force liquid through pipes and fittings.

Helpful Guidelines for Successful Weight Loss Weight loss should occur when you eat fewer calories than you burn. Increasing physical activity while limiting your calories will increase your rate of weight loss. Increasing physical activity will also help you to maintain your weight after weight loss. Discuss appropriate calorie levels and serving sizes with your dietitian. 1. Keep a written food and physical activity journal. 2. Weigh yourself once per week at the same time of day, with the same amount of clothing, and on the same scale. 3. Eat breakfast everyday and do not skip meals. Skipping meals can lead to extreme hunger, overeating and poor food choices. 4. Plan your meals and eat around the same time every day. 5. Pick an eating area at home and/or work. 6. Turn off the TV and/or computer during meals and snacks. 7. Eat slowly. Take 30 minutes for a meal. It takes 20 minutes before you feel full, so wait 20 minutes after your first serving before taking a second serving. 8. Eat protein foods first to help you feel full sooner. 9. Read food labels to help control portions of food. 10. Eat less fat and sugar. Eat more fiber, including fresh fruits/vegetables and whole grains. 11. Limit restaurant and fast food meals. 12. Don’t keep problem foods around the house and/or at work. A problem food is a food that you are likely to eat too much of or too often if readily available. 13. Drink at least 8 cups (64 ounces) of liquids per day. Focus on calorie-free, caffeine-free beverages. 14. Get adequate sleep each night (7-9 hours). Clinical Dietitians, Food & Nutrition Services, UC Davis Medical Center (3/06) © 2006 The Regents of the University of California. All Rights Reserved. Food Preparation Use lowfat cooking methods such as baking, grilling, boiling, poaching, broiling, roasting, steaming or microwaving without additional fat. Avoid or limit frying. Place meat on a rack so the fat will drain off during cooking. Remove skin from poultry before cooking. Trim all visible fat from food (i.e. poultry and meat) before cooking. Use non-stick cookware or cooking sprays. Use egg whites or egg substitute in place of whole eggs. Season food with spices, butter flavoring (such as Butter Buds®), lemon or low-fat dressings. Limit high-fat sauces or gravies such as sour cream, regular salad dressings, full-fat gravy, and cream or cheese sauces (such as Hollandaise or Alfredo sauce). Use a sugar substitute in place of sugar. Replace sugar in recipes with a sugar substitute that can be used in baking or cooking.
SWISS STEAK: THE IMPROVED VERSION OF A CLASSIC RECIPE By Paul Nehring, From NewGrass Farm, LLC, www.newgrassfarm.com Swiss steak was a mainstay of our home kitchen, when I was young, mainly because it was a way to make inexpensive cuts of beef taste taste reasonably good. However, it wasn’t one of my favorite dishes, because even after braising for a couple of hours, the meat was still relatively dry and bland. The problem was that round steak, which was the typical cut Mom used for Swiss steak, is the wrong cut of meat to use. Round steak is lean, and has little collagen in it. While that works well for stir fry, it doesn’t work well for braising. The reason is that collagen, which makes a grilled or pan-fried steak tough, amazingly does the opposite for braised meat. That’s because as it cooks in the liquid, over a couple hours, it starts to break down into gelatin, giving the meat a moist, silky texture. Therefore, if you want the best cut of meat for braising, use a beef cut that has plenty of collagen in it; chuck steak or chuck roast. In this recipe, I use chuck roast, because it’s often much easier to find than thick cut chuck steaks. You just cut your own steaks from the roast, and the price is usually comparable to round steak. This recipe is delicious with mashed potatoes. 2-3, ...
Problem sa zapadnim shvacanjem "stvaranja realnosti" je da to "stvaranje" nije zamena za stratesko razmisljanje i dugorocni cilj. Kratkorocno razmisljanje stvara privid "pobede", "napretka", a nema razumevanja za klice razora koje takav "akciono orientiran" nacin misljenja stvara u samom sustavu.
