A new photosystem-II mutant of the green alga Scenedesmus
obliquus D₃, strain PS-28, has been shown to lack a-tocopherol
(vitamin E). The photosynthetic activity of dark grown samples of
PS-28 is about 20% of the wild-type control. Culturing the mutant
at low light intentisites (10⁴ ergs/sec-cm ²) stimulates photosynthetic
activity...
A new method for the preparation of the 2, 3, 3a,8a-tetrahydro-2-hydroxyfuro[2, 3-b] benzofuran, XXX, ring system has been developed. The synthesis envolved a substitution reaction of phenol, XXIV, with 1-bromo-2, 5-hexadiene, XXV, to give 2, 5-hexadien-l -yl phenyl ether, XXVII. The ether was rearranged via an ortho-Claisen rearrangement to 3-(o-hydroxyphenyl)-l,...
This thesis is the first third of a coming of age novel called i. In this selection the central character, Bea Bouvier, prepares to see her estranged mother on a cruise ship to the Bahamas. She hopes her parents will decide to reunite as a family, though it becomes increasingly...

of provisions being made to provide for appropriate utilization of
the increasing quantities of audiovisual equipment and materials

the study was to identify activities and programs essential to...
Before we apply the laws of probability to hiring practices, a
foundation of basic probability theory will be presented. In this
presentation a number of theorems related to probability will be
proven. These theorems are not necessarily applicable to the problem
which follows; however, they are basic to probability theory...
Field experiments were done to test the relative
effectiveness of single and multiple biological control
agents in reducing weed populations using two insects, the
cinnabar moth, Tvria iacobaeae (L.), and the ragwort flea
beetle, Lonqitarsus iacobaeae (Waterhouse). These two
insects were released for biological control of the biennial weed tansy...
