Missions at Y-12 grow more diverse

Continuing to draw heavily on Bill Wilcox's "An Overview of the History of Y-12 1942-1992," finds Y-12 developing relationships with the National Aeronautics and Space Administration and other branches of the government for work using Y-12's specialized capabilities. Chief among the relationships over the years has been the relationship with NASA. Beginning with a small project (Blood in Gemini) to determine any adverse effects of the weightlessness in space on human blood, this project successfully proved there was no damage to a person's blood when venturing into space. Walker Smith recalled for me his trips to the launch pad, where he personally placed the small metal box containing the blood samples onto the spaceship prior to liftoff. In November 1958, a major labor dispute occurred when the machinists refused to recognize a contract settlement made by the Atomic Trades and Labor Council. An unauthorized strike by the machinists resulted in many of them being discharged but later reinstated with disciplinary action. While labor disputes have been rare over the years, on occasion they did occur. In 1960, the first numerically-controlled machine tool was operated in Building 9212, A-2 Wing. This was a huge step forward in making practical use of the emerging computer technology. Uranium machining made advances and became automated to meet the more sophisticated weapons designs. Dry rooms had to be fabricated to house lithium assembly operations. A follow-on program called NERVA (Nuclear Engine for Rocket Vehicle Application) also eventually failed to meet the need for rockets powered by nuclear energy. Finally, fuel elements were fabricated for PEWEE, yet another rocket that did work well, however, NASA had by then moved to the present-day design of rockets that resulted in them no longer pursuing nuclear energy for power. The "42 Games Experiment" succeeded in making Y-12 the acknowledged leader in the nuclear weapons complex. It was a competition between Los Alamos National Laboratory, Lawrence Livermore Laboratory, Bendix-Kansas City Plant and Y-12. Each machining facility was given 50 blanks. The precision required was 0.0002 inches (two 10-thousandths of an inch). Jack Case selected the Y-12 team led by Bill Nelms with Ken Sommerfeld as engineer and Bob McMillan as statistician. The contest ran for four months. Y-12 was declared the clear winner and thus firmly established a leadership role in precision machining that exists to this day. Another important lesson learned was the value of statisticians working closely with the machining process. Y-12 was practicing statistical quality control before it became the well-known industry standard. The success of the "42 Games Experiment" led to a new philosophy being introduced in Y-12 production processes. It consisted of an approach to instill quality into the product at the source instead of using inspection to weed out the low-quality production parts. This was a major breakthrough in production management thinking and resulted in assigning process statisticians to the production shops. This new approach to production management brought with it an increased awareness of the need for quality to be an integral part of the manufacturing process and brought a heightened sense of quality consciousness. The resulting decrease in the number of "killed" parts proved the effectiveness of the approach. Y-12 continues to operate in this manner today and has expanded the thinking of building quality into all processes, not just the production processes. Another thing that solidified Y-12's "can-do" reputation and its lead in precision manufacturing and fast turnaround was the "18-Day Turn-Around Program." This contest required that production of a weapons part from blank preparation, programming and machining through inspection to be completed in 18 days. Again, Y-12 won the competition easily and consistently produced the required products within the 18 days. One reason for the need for fast turnaround was the much increased and diversified nuclear testing activity at the Nevada Test Site in the early 1960s. At the height of the nation's nuclear testing program, the variety and complexity of test assemblies grew almost exponentially. Design changes were routine and refinements resulted from every test. It was a time of rapid change in nuclear weapons design. By 1963, there were over 1,000 machine tools in a wide variety of over 50 diversified shops across the site at Y-12, mostly located in Manhattan Project buildings that had been converted to meet the changing mission needs. The capability for handling various toxic, hazardous or reactive materials in enclosed and closely-controlled conditions existed throughout Y-12.

What is a Hydroponic Grow Box System? | weed love

A hydroponics system or also know as grow box is a device that is used in growing crops inside a closed contained environment. Generally, grow boxes are used in indoor gardening in which little or no soil is needed to grow the plants. Grow boxes are very convenient for gardeners who themselves do not have a patch of soil to grow in, or by those who lives in high-rise condos who do not have the luxury of having their outdoor garden. Also, a grow box is popular to gardeners who are growing crops all year round and wish to grow plants out of season. In places where winter is principally the climate, the use of grow box is also popular since it allows people in such area to grow off season crops. These hydroponic grow box systems in general is very convenient to use and it also allows the gardener to customize the inside environment to make it conducive for a certain crop to grow optimally.

With the word box itself gives you an idea what a grow box looks like. A hydroponic grow box is characteristically an enclosed system and it contains a built in hps light, intake and exhaust fan, hydroponics system, and odor control system. The hps light inside the grow box serves as the artificial sunlight that helps plants inside the box with photosynthesis. Intake and exhaust fan is also installed to control the temperature inside the grow box since temperature also plays a vital role in the development of plants. Hydroponic system or water system is the one that gives the nutrients required by the plants inside a grow box. In addition, an odor control system is also installed to minimize the smell that comes with fertilizers and other composts stuff which is part of plant growing.

There are also advance grow box units that also includes air conditioning as well as CO2 generators. They have included in these installation to fully maximize the capacity of a hydroponic grow box. They use air conditioning to have better control over the temperature and keep running temperatures down. As for the CO2 generators, it increases CO2 level inside a grow box which assists the plant to use the excess water and energy that is stored in the leaves. As a result there is substantial increase in the growth rate of crops that uses chlorophyll in the process of photosynthesis with the help of CO2 generators installed inside a grow box.

Grow boxes are becoming more and more popular these days as it allows people to grow gardens inside their homes with a hassle free kind of work. Hydroponic grow box system is also used in agricultural research as this allows researchers to have full control over their experiments. Even young generations are now keen on indoor gardening as a hobby. Aside for its eco-friendly characteristic, a hydroponic grow box can be a good indoor decoration which adds beauty and glamour to the interiors of your homes. This is why grow boxes are preferred by those who lives in the city yet wishes to blend a little nature in their city lives.
