faced with a Detroit plant that is no longer viable because of underinvestment‚ labour issues‚ and product-process mismatch. This has lead to low sales figures‚ low return‚ and high burden rates (as calculated by the company). The issues at the Detroit plant will be reviewed and options will be presented. A recommendation to address the Detroit plant will be be made based on this review. Issues: Investment in the Detroit plant has lagged significantly from other plants in the corporation.

Issue: The main problem with the two plants‚ Phillips and Crawley is the quality of the twelve types of modules which falls below 95% level and the other issue is regarding the quality acceptance level of all the modules. We have come up with the recommendation which will help to solve the issue of quality problems of all the modules including the twelve types of modules.

arrow-shaped leaves. The plants resemble the heartleaf philodendron with leaves that solid green or variegated with white‚ yellow‚ pink or silver veins. It is very attractive as a potted plant; however‚ as the plant matures‚ it gradully developes long trailing stems and the leaves become larger with three to five lobes. When this happens‚ you either must plant it in a hanging planter or use some type of support such a stake or pole for it to grow up on. If you would rather have your plant remain small and

Allelopathy and interference and the effect they have on plant growth. Allelopathy occurs in plants. Many plants produce chemicals that may be harmful or beneficial to other plants. In some cases a species can produce chemicals that can prevent the growth or germination of another species. An example of this is Australian native plants such as Casuarinas and Eucalypts which produce allelochemicals that prevent competition of other plants. This is a form of a defence mechanism in order to survive

spectrum causes plants to grow faster. The prediction was that read light would cause the most growth in plants and that blue light would result in slower growth. The results did not support the hypothesis. Referring to table‚ one can see that blue caused both the spinach and radish plant to grow the most and that green light cause the plants to grow less. Spinach is a long-day plant therefore it was able to grow better under a constant light source. This would have aided in the plant growing faster

How about positive controls? Are there some plants which you know will grow well under the conditions that you are specifying? Are you using these as positive controls‚ while your test plants will be a different type of plant? 2. I suspect they also include a method of checking‚ periodically‚ for results "over
