The earliest food production in greenhouses was possibly the growing of off-season cucumbers under "transparent stone" for the Roman Emperor Tiberius during the first century. The technology was rarely employed, if at all, during the following 1500 years. During the 1600&39;s several techniques were used to protect horticultural crops against the cold. These included glass lanterns, bell jars, cold frames and hot beds covered with glass. In the seventeenth century, low portable wooden frames covered with an oiled translucent paper were used to warm the plant environment much as plastic row covers do today. In Japan, straw mats were used in combination with oil paper to protect crops from the severe natural environment. Greenhouses in France and England during the same century were heated by manure and covered with glass panes. The first glass house built in the 1700&39;s, used glass on one side only as a sloping roof. Later in the century, glass was used on both sides. The glasshouse was used for fruit crops such as melons, grapes, peaches and strawberries and only rarely for vegetable production. The developers of this new technology kept market profitability in mind: they produced crops which appealed to the wealthy and privileged, the only people who could afford the luxury of fresh fruit produced out of season in greenhouses. Greenhouse food production was not fully established until the introduction of polyethylene. In the U.S., the first use of polyethylene as a greenhouse cover was in 1948, when Professor Emery Myers Emmert at the University of Kentucky, used the less expensive material in place of more expensive glass. Professor Emmert is considered the father of plastics in the U.S. because he developed many principles of plastic technology for agricultural purposes through his research on greenhouses, plastic mulches and row covers. The development of hydroponics has not been rapid. In the U.S., interest began to develop in the possible use of complete nutrient solutions about 1925. Greenhouse soils had to be replaced at frequent intervals or be maintained from year to year by adding large quantities of commercial fertilizers. As a result of these difficulties, research workers in certain U.S. agricultural experiment stations turned to nutrient solution culture methods as a means of replacing the natural soil system with either an aerated nutrient solution or an artificial soil composed of chemically inert aggregates moistened with nutrient electric portable cooler solutions. Between 1925 and 1935, extensive development took place in modifying the methods of the plant physiologists to large scale crop production. Workers at the New Jersey Agricultural Experiment Station improved the sand culture method. The water and sand culture methods were used for large scale production by investigators at the California Agricultural Experiment Station. Each of these methods involved certain fundamental limitations for commercial crop production which were partially overcome with the introduction of the sub-irrigation system initiated in 1934 at the New Jersey and Indiana Agricultural Experiment Station. While there was commercial interest in the use of such systems, hydroponics was not widely accepted due to the high غير مجاز مي باشدt in construction of the concrete growing beds. In the post-W.W.II years, there was a bloom of interest in the Southwest US in gravel culture of tomatoes and cucumbers. However, the systems were not perfected and were eventually abandoned. After a period of approximately 20 years, interest in hydroponics was renewed with the advent of plastics. Plastics were used not only in the glazing of greenhouses, but also in lining the growing beds rather than beds made of concrete. Plastics were also important in the introduction of drip irrigation. Again, numerous promotional schemes involving hydroponics became common with huge investments made in hydroponic growing systems. Escalating oil prices, starting in 1973, substantially increased the غير مجاز مي باشدts of CEA heating and cooling. This along with fewer chemicals registered for pest control caused many bankruptcies and a decreasing interest in hydroponics.Almost another 20 years have passed since the last real interest in hydroponics, but growers are once again establishing CEA/hydroponic systems. This is especially true in regions where there are environmental concerns in controlling any pollution of groundwater with nutrient wastes or soil sterilants. Today growers appear to be much more critical in regard to site selection, structures, the growing system, pest control and markets. ادامه مطلب

With a paid app development tool, you can quickly create your own Android app. Google has already discussed the possibility of Android apps in the future, but they haven&39;t yet finalized it. In short, we are talking about Android Kit, the programming code that will allow your app to run on Android devices of all flavors such as Gingerbread, Honeycomb, Kit Kat and Ice Cream Sandwich. It is an open source, community-driven framework written in dart that works just like its counterpart Android Native apps but also allows you to create mobile apps that run on both iOS and Android. This is one reason why many companies across the world are considering using it for their business development needs. Therefore, while using flutter apps you&39;ll be able to enjoy high quality widgets and community support. This means that your apps built using flutter app development will be much faster than your regular Java based apps. Android Native apps are written in a hybrid of C++ and Javascript that runs inside the Android system, on top of a Java virtual machine. Even though it&39;s written in JavaScript, it works extremely quickly.. This kit was originally developed by the Android team but now it is available to developers through a commercial program called The Kit. The flutter app development framework used by Facebook is quite unique and innovative. It&39;s written in high performance JavaScript and so runs extremely fast. With the use of this amazing cross-platform framework, you don&39;t have to worry about any porting problems. But what&39;s so unique about this programming language flutter app development? As mentioned above, it&39;s written in a hybrid of JavaScript and dart. First of all, because the framework is written in dart, it can be written on iOS as well as Android, allowing developers to use the same code on both devices.Flutter is an amazing Google UI tool for developing great android, web &38; desktop startup app in a single codebase. But what if you want to develop mobile apps that run on both iOS and Android? That&39;s precisely where Flutter comes into play.

But just imagine how your car has handled this particularly rough season. Before it&39;s time to drop the top or roll down the windows for a summer road trip, it&39;s wise to have a mechanic give your ride an all-over inspection to look for rust. This might not be the most enjoyable time of year to take a little extra time, but it&39;s necessary. A good body shop can quickly repair smaller rust spots and can sometimes even work wonders on bigger problem areas. Consider it the "top coat" for your car&39;s manicure. Wax doesn&39;t just make a car look great, it also acts as a protective coating. Once rust sets in, it continues to chew away with abandon until the car can no longer be saved. Garages can get warm, making ice and dirty snow stick to the car and "breed" into destructive rust. However, the real effort starts at home. Warmer Weather As soon as the weather starts to improve, start parking outside. For many vehicles on the roads, parked in driveways or even "protected" in garages while dripping wet, one tough winter can lead to rust spots-and if they&39;re not treated, they can eat a machine alive. Rain, sleet, snow and ice, coupled with salted roads in some regions, can lead to more than just a case of Vitamin D deficiency. But don&39;t panic. There&39;s no substitute for all-weather rubber mats, and don&39;t count on factory mats to keep the car protected. Snow and ice keep salt suspended, and a rinse can open your vehicle up to all kinds of damage. When getting into the car, make sure your shoes are China portable freezer manufacturers as free from snow as possible. Melting snow mixed with salt can easily sink into the carpets, causing floorboard rust that you might not even notice until it&39;s too late.As we head into spring, many drivers might be feeling a bit blue with all those April showers on deck. Another option is an engine block heater, used at night, particularly for those with new or collector cars who want to keep them protected from the outdoor elements. However, as soon as the temps start to climb, this is the green light for a wash. Winter Care In the throws of those snow storms, make sure you keep those floors clean. Ensure you regularly wax your car along with routine washes, but the former step is especially important in the autumn before the first winter snow falls. However, it&39;s not too late to start practicing rust precaution, or perhaps making an appointment to get those new rust spots nipped in the bud. At the same time, purchase or replace some sturdy rubber floor mats to keep the interior protected. It&39;s like a spring physical for your car, and well worth the preventative care. While regular washes are smart, this doesn&39;t hold true when temperatures drop below freezing. Many collision repair shops specialize in custom paint jobs, restoration and repairs to rust. Once spring has officially sprung, it&39;s time for a full inspection. Recycled water might have salt from previous cars-a good goal is to wash it weekly. Make sure the underbody gets a good spray with fresh (not recycled) water ادامه مطلب
