Here we present a phylogeny of beetles (Insecta: Coleoptera) based on DNA sequence data from eight nuclear genes, including six single-copy nuclear protein-coding genes, for 367 species representing 172 of 183 extant families. Our results refine existing knowledge of relationships among major groups of beetles. Strepsiptera was confirmed as sister...
Vibrio marinus MP-1 (ATCC 15381) deaminated nine of seventeen
amino acids tested with L-glutamine being deaminated to the greatest
and L-serine to the second greatest extent in one hour. The optimum
pH for the L-serine deamination was 8.4.
The response of washed cells to temperature on the deamination
of L-serine...
The marine psychrophilic bacterium Vibrio marinus MP-4
possessed a maximum temperature and hydrostatic pressure of
20 C and 425 atm for growth. The effects of temperatures of 21 and
25 C and hydrostatic pressures of 200, 400, 500, and 1,000 atm on
protein, RNA and DNA synthesis by V. marinus...
This paper is a study of various linear Metal-Oxide-
Semiconductor integrated circuit configurations with the
goal of improving their operation. The operation of MOS
devices is covered including their use as load devices
to replace diffused resistors. The advantages and disadvantages
of the resulting circuits as well as possible
physical...
The colonization of several species of plants by vesicularar-buscular
mycorrhizae (VAM) was studied to determine how host, soil,
or symbiont factors interacted to enhance growth of the host plant.
Seedlings of two species of the Cuppressaceae and two of the
Taxodiaceae formed VAM; colonization significantly improved growth.
This response to...

Fingered robot hands are complicated systems made of three essential system components: its morphology, its actuation, and its software control. These system components are tightly coupled to each other. Due to this, it is hard to benchmark robot hand performance in a way to understand the contributions of the individual...
In this paper, we provide a thorough proof of most of Bertrand's Theorem. Using Arnold's book "Mathematical methods of classical mechanics" as a backbone and calculus methods demonstrated by Jovanović in his article "A note on the proof of Bertrand's theorem," we show that for masses in a central field...
