In the article we present today we develop some of the main benefits of cover crops compared to conventional covered by data from different studies.
During the summer months, urban areas can reach temperatures of 1 to 4.5 C above those with their surrounding areas, a phenomenon known as the heat island effect. table top food warmer The gradient varies, depending on the climate, topography and urban design.
One of the main reasons the heat island phenomenon are extensive surfaces having built the cities, table top food warmer where solar radiation is absorbed and accumulates as heat slowly emerges throughout the night. This phenomenon can be quantified by parameters such as the albedo, which refers to the amount of reflected radiation on a surface, in relation to the total received. Expressed in% with 0 being the lowest percentage table top food warmer of reflection, and therefore leading to increased heat absorption by the surface. The albedo of an asphalt roof finish is approximately 8%, while a green tire is 25%.
Moreover, the ground cover, besides having a greater ability to reflection of solar radiation, also cool the air in its surface known as transpiration process where the plant absorbs moisture from the ground and ejected in the form of vapor water.
These two qualities together, allow the temperatures reached in a green cover are lower than those of the conventional tire. As a covering of asphalt can reach 70 in a summer table top food warmer day, a surface finishing plant does not usually table top food warmer exceed table top food warmer 26 C.
The Environment Agency of Canada conducted a study which concluded that planting at least 6% (6.5 million square meters) of surface coverings Toronto could be reduced by 1-2 C air temperature in Summer city.
The development of our municipalities leads to a loss of soil permeability, table top food warmer which prevents rainwater can filter through the streets finishes and although it has sewage systems, many times these are insufficient address table top food warmer major downpours.
Mulches have the property to retain rainwater, reducing the number of liters to evacuate in time that are occurring table top food warmer rainfall. The storage capacity depends on the design of the cover, but in all cases the existence of these constructive solutions involves a reduction in the amount of runoff water to evacuate the system and a decrease in velocity as the water is stored in the retaining layer and the substrate.
According to the German standard DIN 1986, Part 2, the coefficient of storm drainage for landscaped areas with a minimum of 10 cm thick, is 0.3. This means that only 30% of the rainfall drains and 70% is retained in the green roof or evaporates. FILTER table top food warmer POLLUTANTS AND CONSUMING SUBSTANCES CO2
Plants are able to absorb a certain amount of volatile toxic elements in the air, turning into organic matter. Much of urban pollution is formed by nitrogen compounds, predispositions traffic and industry. Plants capture these compounds and use them as nutrients. A green cover 60 m 2 is able to catch and process 15 kg of heavy metals. (Darlington, 2001)
This quality is supported by several studies. Bartfelder showed that in the central districts of highly polluted cities, heavy metals table top food warmer are taken up by the leaves (Bartfelder and Kohler 1986). Furthermore, measurements on a Swiss Federal Street resulted a hedge 1m high and 0.75m in width reduced by 50%, through its filter effect, table top food warmer lead contamination (mentioned by Lötsch 1981).
Another feature to consider is that particles of dust and dirt remain attached to the leaves and are then washed away by rain towards the substrate covers that also acts as a filter reducing the load of pollutants table top food warmer reaching sewers. 1 m2 of vegetation traps 130 grams of powder per year. (Darlington, 2001)

The universe is made of energy and matter (which itself is a condensed form of energy). Energy alfa tech india can not be created or destroyed but can take many forms and change from one form to another type.
Matter itself has internal energy and particles are in constant motion. An isolated body retains its internal energy. Anywhere in the universe where matter exists, there will be a measurable amount of heat energy.
When a particle "energized" contact less energized particle will happen a 'thermal transfer alfa tech india "particle energy" hot "to" cold "particle until both particles reach an average level of energy called" thermal equilibrium ".
The particle "energized" apply a force to the "less energized" by increasing its rate of vibration, so that the particle will require more space, and leave the balance in which it was before being energized.
At the same time, will occur a "waste heat" to come off in different "bosons" of energy alfa tech india called "phonon" alfa tech india .The process of energy transfer is accomplished in two basic ways: by "driving" alfa tech india (enthalpy) in which includes "convection" or "radiation" (entropy).
In fluids (liquids alfa tech india or gases) classical physics calls this phenomenon "convection". As molecular alfa tech india fluid forces are weaker, the excitation of the particles increases the pressure on the walls of its container, generating kinetic alfa tech india energy in the particles with mass interacts with other forces causing the movement of atoms and molecules a cold to a point hottest point.
Radiation heat transfer alfa tech india is via electromagnetic waves where the phonon needs no medium for transferring energy from the emitter to the absorbent. One example is the energy from the Sun to the Earth heat.
The "specific heat" of a material is the ability of a unit mass of the material for energy or heat to raise its temperature 1. This varies according to the density of matter.
These turning points are: melting alfa tech india (solid -> liquid), freezing (liquid -> solid), evaporation (liquid -> gas), condensation (gas-> liquid), sublimation (solid <-> gas) or ionization ( gas-> plasma) alfa tech india according to the change.
The unit of measure of the "warmth" is the same as that of "energy" and "work": alfa tech india the joule, but also commonly use the "calorie". As the value of such a small Coloria normally use the nutrition value of kilocalorie (1,000 calories).

The retained heat cooking is a technique that involves using the heat of the accumulated food during cooking so that in a thermally insulated container finish their development without energy expenditure. Our abundance of energy has led to the neglect of this ancient technique heater battery of cooking food. Today, however, takes a fresh impetus with new insulation and practical ecology hand materials. This report documents this revolutionary cooking method saves time and energy, something very necessary in the XXI century. In Anglo-Saxon literature references abound to this type of cooking known as retained heat cooking (Retained-heat cooking), cooking without fire (fireless cooking), hay box (haybox cooking), or wonderful box (box wonder cooking).
Preparing a box hay. Photo preserved in the collection of Rare and Manuscript Collections of the College of Human Ecology at Cornell heater battery University Library. Photo signed by Troy for the Bulletin H-135, in an article entitled '' Fireless and Steam Pressure Cookers. ''
The experience heater battery of cooking without heater battery fire (fireless coking) may seem strange. In reality, however, is something that was popular, but perhaps the most appropriate concept is the retained heat cooking (Retained-heat cooking). In our country is traditional for cooking chestnuts roasting cease-fire after a few hours wrapped in blankets so they were more tender with the retained heat cooking itself. But it is also true that, probably heater battery the need for more calorie recipes and cooked or legumes, favored the emergence of wit to let these were completed under the covered and wrapped in straw (hay boxes) pot, an insulating natural. Thus, using the residual heat stored in the food itself, was achieved than 3 or 4 hours later were to the point, with considerable heater battery energy savings in coal or wood. In any case, the so-called retained heat cooking heater battery without fire or received in the early twentieth century an unprecedented attention as evidenced by certain heater battery graphic documents.
Thus, in the early twentieth century, is published in New York a book by Margaret J. Mitchell (1913), The Fireless Cook Book: A Manual Of The Construction And Use Of Appliances For Cooking By Retained Heat With 250 Recipes. This book, published in facsimile version today by Kessinger Publishing, heater battery includes not only the different techniques to harness the heat retained by cooking, but it is also accompanied heater battery by a number of recipes. However, despite this documentary reality, the appearance of fossil fuels, gas and electricity, soon left this technique into oblivion. This book itself is already an "ecological rarity", but it is also an argument about how to save time, energy and, in turn, get nutritious and good tasting food. The work of Margaret J. Mitchell not only provides a review of the techniques with their advantages and disadvantages, but also checks how the dishes that traditionally require boiling or steaming, saving fuel could be prepared with the insulated box. And all this with surprising results from a culinary point of view.
The mills to harness the heat retained as they have an important development in the early twentieth century, as evidenced by other works like Constance C. Radcliffe Cooke (1917) The Cooking-Box: How To Make And Use It, Together Eighty With Economical Recipes Adapted For Fireless Cookery, used as a textbook in local centers kitchen and cooking schools throughout Britain and the United States (between 1918 and 1919). There is also information about the existence of hay box manufacturers to cook "without fire". The rise of social interest in cooking with retained heat could also be explained by the difficulties and shortages caused by World War II. Anyway, soon also was related not only to energy heater battery savings, but also saving of time involved in these techniques to women's liberation, so some clubs liberal women's promoted as the "revolutionary cooking without fire": a domestic innovation for saving time and energy resources. Currently, most of the mills for the use of retained heat are either homemade or are intended heater battery for technology transfer projects for fuel, especially wood, in countries where v

Institutions that want to protect us from the scorching heat of these days we recommend not leaving home at times of maximum sunshine. But we will have chosen a couple of plans you dare to walk on the wild side of life and this weekend convirtáis fan in a coming and going of various stimuli.
The artist SAM (Bachelor of Fine Arts and -Megadeth's bass musician DOVER- group) with an invoice between the art-brut and punk and a clearly anthropological vision has in Lavapies Swinton Gallery exhibition "The Schlagen Richten Collection" objects , sculptures and posters showing, for relics, the story of a forgotten civilization.
This Saturday July 19 at 12: 30h also an interesting encounter between the artist and Javier Duero, independent curator and cultural producer is celebrated. In his talk, open dialogue, reflect on contemporary society and its influence on contemporary artistic creation.
Does the fact that certain artistic creation is generated with a social orientation, legitimate and socially? What are the mechanisms that could improve the relationship of art sector of society? Is public of contemporary art always the same; some produce, while others narrate and documented? Do we really transcends contemporary art to society? They are some of the issues desgranarán Saturday and invite you to participate.
The Restless Culture Festival celebrates its fifth successful edition in Getafe and can even hasten their proposals. food pans Between 9 and 19 July brought together the likes of Goran Bregovic, Manu Chao, The Sonics or Mala Rodríguez but will Calexico, The Sonics, Depedro or The Asteroids Galaxy Tour artists food pans will close this weekend's festival .
Festival director John Yuste, is largely responsible for the growth food pans and impact of the event as it has always worried that his was a different poster and varied: "Every day is designed to pay tribute to music. From roots music Goran Bregovic, the rock of The Soft or hip hop with Mala Rodríguez, "said from the organization.
"A couple of years ago we celebrated the festival at a local Getafe holds very few people. Today, two years later, we have an arena with seating for 5000 people and a strong international food pans cartel "he added.
"If there must be a revolution ... [...] have to be a party." With a sense of humor, elegance and subtlety, Alicante photographer Cristina de Middel food pans plays hide and seek with words and images and transforms the "Red Book of Mao" in a Decalogue of the perfect party. So PARTY start the project and exhibition until Saturday to see and enjoy at The New Gallery in Madrid.
An acidic review of China, communist, capitalist and bipolar, which has earned PHotoEspaña Award for Best Book of autoeditado Photography. It's the ultimate success food pans of one of the photographers with more international projection, based in London, and supported by other awards including the Annual Infinity Awards and nomination Deutsche Börse Photography Prize in 2013. Since we were surprised last year with "Afronautas" project that became the first Spanish to win the Photo Folio Review food pans Rencontres d'Arles in.
In Party, as with a scalpel, De Middel dissects the founding text of Mao and does the same country as the speaker, censorship and delete parts of the text that make no sense and very intentionally writes a new present to China.
Organized by the Association of Designers of Madrid (DIMAD) exposure "Agitators of Conscience" remember "Graphic design has the power to make us change the vision of the world", in the words of the Japanese poster artist Shigeo Fukuda.
A scenario in crisis, a changing reality for the middle classes - major consumer advertising and products - require the design to reinvent themselves and become involved and this exhibition is a design specimen political and social activist whose sole function food pans is to understand that graphic food pans design It is more than a generator of products and "most beautiful things". In the images shown there is a very interesting food pans aspect is that as explained Ofelio Serpa, curator of the exhibition, food pans "each of which is presented in a way hardly neutral or" apolitical "and his strength and his graphic discourse is precisely in Therefore, the ability to evoke and encourage people to think, and if possible, to act ".

GPUs affect the performance of a PC in a more direct way than a few years ago. And is that not only serve to speed up the games, but also multimedia and compute-intensive applications.
In the past five years have increased dramatically the complexity and capacity parallel processing of graphics processors. In fact, evolution rivals that of general purpose microprocessors, allowing them to rub shoulders with them today in scenarios where applications are executed simultaneously.
The development of the graphical logic is simple. Make the most of your processing power requires some knowledge available almost exclusively for gaming enthusiasts. Fortunately, AMD and NVIDIA are getting their drivers are becoming more stable and affordable rational scc61 once so that even the less skilled users can intuit what to do to improve rational scc61 the quality of its graphics.
The purpose rational scc61 of this practical is to help you deal effectively with the issues that most often hinder the proper functioning of your graphics card. And, once again, users have broad leeway rational scc61 enough to solve many of the problems that we encounter. 1. Attention to cold welding
Although, fortunately, is not one of the most common rational scc61 problems that we often run into occasionally malfunction of a graphics card is due to the weakened welding of one or several contacts from the GPU. This is a serious problem, which usually causes no image appears rational scc61 on the screen of your monitor, because the graphics processor does not establish proper communication with the PCB.
If your graphics card does not work, you have ruled out any other reason and believe that its origin is a weakened welding, we encourage you to try the procedure of overheating using a heat gun. You may buy this accessory rational scc61 for 20 or 30 euros (depending on model) in many electronics stores or DIY.
Heat guns seem a little boring, but as we as its name suggests, serve to project a beam of intense localized heat, able to significantly exceed 100 degrees Celsius. For this reason, we feel obliged to insist on the need not address this task unless you are convinced it is your last option. No we guarantee you attain solve your problem, but often works. And not only with graphics cards, but also with motherboards for laptops and game consoles.
As the heat emitted by the gun could damage the surface, it is best to place the graphics card above a surface other than metal. For example, you can place the card on a wooden board we do not need in the future. Then colocad on the gun, if you have a narrow nozzle rational scc61 nozzle to project heat more accurately. rational scc61
Then ApliCAD encendedla and heat on the GPU using the minimum power, which is typically slightly less than 100 degrees. rational scc61 Incline gun to expel the heat as close as possible to the base of the graphics processor, and realize a circular motion around the chip for 3 to 4 minutes. Let cool card and when you can touch the surface of the GPU without burn you, instaladla back into your computer and Ignite. If not, repeat this process again, but slightly increasing the temperature of the gun.
In some Internet forums, you can find testimonials from users who have managed to repair their graphics cards and their base plates sobrecalentándolas consoles. To this end, introduced for a few minutes in a conventional oven, of which use to cook food; and other wrap them in cloth and set in motion to override heat dissipation and cause overheating searched.
The objective is the same as when using the gun aim, only with these two methods, heat is applied to the entire printed circuit board form a less localized, so could damage some other component such as capacitors. Stabilizing card 2.
For those users who practice and fail to stabilize overclocking your graphics card, or improve their performance after having rational scc61 forced, it is best to install a water cooling system. This solution may be very advantageous to dissipate heat more effectively releasing the CPU and GPU, which will also allow dilate life.
The integration of this component in a PC is not difficult. Roughly speaking, you must install the pipe loop by which fl

Does a heat pump below zero? | Nergiza
It has always been said that heat pumps are not recommended at very low temperatures, as they lose a lot of capacity and performance is very bad. We will see in this post if this is one of those statements that is outdated or whether it remains true.
We will try to explain without going into too much technical detail or Mollier food warming equipment diagrams, etc ... A heat pump works by passing a gas to liquid phase in the indoor unit (gives food warming equipment off heat) and driving him into the gas phase on the outside (absorbs heat = emits cold), so there are two key pressures food warming equipment in the system: high (heat) and low (cold). While not exactly true, we say that the difference between the high pressure and low is always a fixed value.
The first reason why the system does not work well at low temperatures is that as the outside temperature decreases, the low pressure also decreases, and as the difference between high and low is constant, high also decrease, causing the temperature in the indoor unit is lower and therefore less powerful heating.
The second reason is the defrost, if the outside temperature is eg 0, we must evaporate (outdoor unit) to just under temperature to absorb heat from the air, so there will be zero temperatures in the computer battery, which It will hence freezing ambient humidity, creating ice.
The heat pump equipment are equipped with mechanisms that detect this situation and reverse the cycle, going to heat in the outdoor unit and cool on the inside for a while to melt the ice formed so we can continue to operate correctaemente. This defrost cycle, as you will understand, decreases computer performance and heat capacity because for a while "produces cold" in the indoor unit.
To begin, it is necessary to say that this should not be a problem never, food warming equipment now or in the past, because you can just check the capacity tables / temperatures and select a team the necessary power when we have the minimum temperature the area where it is installed.
If I calculated the heating demand my local and I think 18kW, I can be naive and select a team of 20 kW rated power (which comes in the catalog) as the table, but when the outdoor temperature is -5 C, my computer will barely 12kW, so it will not be enough. Solution: select a team of 18kW at -5 C or at the minimum temperature that exists in the area.
Although not all manufacturers have them, today there are teams that have solved this problem with various technologies. Let's see eg Mitsubishi Electric equipment of Zubadan range.
For example Zubadan 5cv equipment (orange line) retains its nominal heating pontencia (14kW) food warming equipment to -15 C, even at -25 C is more capable of 10kW. While an inverter team "normal" (blue line) announces such as rated power 14kW and gives only 5 C outside tempeartura, when low tempeatura at -15 C is only able to give a 7kW.
Mind you, this only means that the Zubadan team will be able to "not let you pulled" when the outside temperature is low, have not talked about application efficiency in these cases it will be much worse than normal food warming equipment outdoor temperature (5 C).
Although each has his methods, in general way is to inject liquid phase refrigerant (from the condenser outlet) food warming equipment in the compressor when low outdoor temperatures are detected. We will not go much into this as it would be outside the scope of Nergiza (energy for all audiences).
The conclusion is clear, if someone complains that your heat pump not properly calefacta the days of low outdoor temperatures, the fault is not the computer if not the designer who designed the installation, the installer has calculated ojímetro or our dear friend TodoEnMenaje SL seller who has sold us a team based on the square footage of our local.

Geothermal energy as defined by the German VDI 4640 guide adopted by the European Council of Energy, is that energy as heat stored beneath the solid surface of the earth. It has some features that make it particularly attractive; it is a renewable and continuous power, since the heat is unlimited. It is also a clean energy because it does not contribute to the emission of greenhouse gases. And finally it is an energy efficient, since it enables high yields by the stability of the underground temperature.
The first attempts to take advantage of geothermal energy for electricity production occurred gev online in the early twentieth century by the Italian Prince Piero Gioroni Conti; 250Kw the first plant built in 1913. US and Indonesia begin to use geothermal energy for electricity gev online production in the years 1925 and 1930, and is in the 70s when a growing number of countries producing geothermal-electric coinciding with the oil crisis. gev online In the 90 growing use of geothermal energy by the commitment to the environment and concern for the CO 2 again.
The non-electric use of this type of energy began in the early nineteenth century Landarello to obtain Boro, who held a monopoly on the extraction for 25 years. The low pressure steam is used for heating greenhouses gev online and buildings in Tuscany between 1910 and 1940. In 1892 gets the first geothermal district heating system in Boise, Idaho (USA) continues in operation today in operation . Today the most common non-electric use is represented by the use of heat pumps with 34'80% in terms of installed capacity, followed bathrooms with a 26'20% 21'62% heating, gev online greenhouses 8'22 %, 3.93% aquaculture and industrial processes 3'13%.
As shown in the graph, gev online geothermal installed gev online capacity is 958MW Mexico and obtained four geothermal fields: The Azufres with 188MW, Los Flue 40MW, 720MW Cerro Prieto and Las Tres Virgenes with 10MW. In the last five years there has been no significant increase, however the draft Cerritos Colorados 75 MW, 2014, coinciding with the planned closure of some older units are planned.
When talking about geothermal energy and its use, we must differentiate the various ranges of potential enthalpy geothermal reservoirs of the globe, ranging from the exploitation of the resources of very low temperature (below 30 C) to applications high enthalpy (150 C). In between these two types of resources have average gev online temperature (between 90 and 150 C) and low temperature (30 to 90C ).
The low enthalpy geothermal applications are based on capturing the heat contained in the earth's crust; this heat comes largely from solar radiation, and to a lesser part of the heat from the core, the temperature gev online is 4000 C.
To extract this heat content in the rocks will need a transport system, generally water, that leads the heat to the surface. These transport systems to be discussed later are called geothermal probes, horizontal collectors, geothermal foundations, etc.
Geothermal foundations are a particular case of geothermal probes that increasingly has more followers. It is converting the foundation of a building in a field probes, sensors tubes where the metal armatures piles are secured. The heat exchange circuit is located under the building, gev online so that work and saves space. Recall that even in the coldest climates, soil temperature remains stable at about 10-20 meters around 12-14 C. It is essential to the accurate calculation of the resistant section, that in no case will fall on the sensors, so oversizing of the structure will be necessary.
The first law of thermodynamics is known as the law of conservation of energy, states: energy is neither created nor destroyed, only transformed or transferred from one system to another. Heat transfer and thus the performance of work are two ways to extract or supply power to a system.
The second principle, which takes into account the operation gev online of a heat pump, determines that they contact when two bodies are at a different gev online temperature, a heat transfer ranging from cold to hot focus focus occurs.
Once reviewed these two concepts we define the heat pump as a machine capable of transferring energy from cold to warm focus focus, using a small amount of energy in the form of work that gives the outside; are
