Optimum Tail Plane Design for Sailplanes

Classical drag equations in a modern version were used to calculate the influence of tail modifications on the drag of a standard class sailplane. The profile drag which depends on the Reynolds number is included in the calculations. Minimum drag is compared with real drag for two lift coefficients. Some results have no clear tendency but low tail area and relatively low tail aspect ratio give some advantages. Optimum and real lift ratios between wing and tail plane are compared for the original sailplane

QTL Analysis of Mineral Content and Grass Tetany Potential in \u3cem\u3eLeymus\u3c/em\u3e Wildryes

Grass tetany is a metabolic ailment in ruminants, occurring when animals graze rapidly growing C3 grasses with a K/(Mg+Ca) ratio (KRAT) greater than 2.2. High KRAT values have been documented in several forage grasses including diploid Russian wildrye (Jefferson et al., 2001). The objective of this experiment was to identify quantitative trait loci (QTLs) controlling KRAT in allotetraploid wildryes

Roles of Matrix Metalloproteinases in Cutaneous Wound Healing

Wound healing is a complex process that consists of hemostasis and inflammation, angiogenesis, re-epithelialization, and tissue remodeling. Matrix metalloproteinases (MMPs) play important roles in wound healing, and their dysregulation leads to prolonged inflammation and delayed wound healing. There are 24 MMPs in humans, and each MMP exists in three forms, of which only the active MMPs play a role in the pathology or repair of wounds. The current methodology does not distinguish between the three forms of MMPs, making it challenging to investigate the roles of MMPs in pathology and wound repair. We used a novel MMP-inhibitor-tethered affinity resin that binds only the active form of MMPs, from which we identified and quantified active MMP-8 and active MMP-9 in a murine diabetic model with delayed wound healing. We showed that up-regulation of active MMP-9 plays a detrimental role whereas active MMP-8 is involved in repairing the wound in diabetic mice. These studies identified MMP-9 as a novel target for therapeutic intervention in the treatment of chronic wounds. A selective inhibitor of MMP-9 that leaves MMP-8 unaffected would provide the most effective therapy and represents a promising strategy for therapeutic intervention in the treatment of diabetic foot ulcers

Role of magnesium in plants

Magnesium is one of 13 mineral elements required by plants and one of at least 17 required by animals. The element was first isolated in chemically pure state by Sir Humphry Davy during the years 1807 to 1812 and its necessity for plant growth was shown by J. von Sachs and W. Knop in the 1860's. Its presence in the chlorophyll molecule was detected by R. Willstitter in 1913. More details on the history of Mg research appear in earlier reviews (1, 8, 11 and 20)

Air-Flow Planimeter for Measuring Detached Leaf Area

An apparatus has been designed and tested for measuring area of detached leaves of all shapes. The apparatus is easy to operate and gives accurate results rapidly. Measurement variability is generally less than 1%

Selenium in Soils and Plants

Prior to 1960, selenium was important because of its uptake by selenium-accumulator plants and its subsequent toxicity to animals eating these plants. The first reports on the nutritional importance of selenium were published in 1958, and attention was then drawn to another aspect of selenium.¹ The growing incidence of nutritional muscular dystrophy in animals on improved postures was soon identified as a selenium-responsive disorder (Figure 1). Since then, a large amount of literature has accumulated on various aspects of selenium in the soil-plant animal system. Reviews include those by Allaway et al.,² Klayman and Gunther,³ the NRC,¹,? and Oldfield.? This article reviews the role of soil and plants in selenium cycling to the animal and the return of selenium to the soil
