Type Ia Supernovae are in many aspects still enigmatic objects. Their observational and theoretical exploration is in full swing, but we still have plenty to learn about these explosions. Recent years have already witnessed a bonanza of supernova observations. The increased samples from dedicated searches have allowed the statistical investigation of Type Ia Supernovae as a class. The observati...

to work with non-pathogens may be tempted by the availability of funds to focus on pathogens and submit grant proposals to a biodefence programme. But this too has financial implications, because dangerous organisms can be investigated only within expensive, high containment facilities. Moreover, there is considerably less existing knowledge to build upon in the case of most pathogens than exis...

Electrical Engineering (ABSTRACT) Hardware description languages (HDLs) such as VHDL have made it possible for circuit and board designs to be done without resorting to paper, allowing computers to manage the design database and automate the translation between various representations of the system. Although VHDL modeling can provide a bonanza of benefits, VHDL models must be used effectively t...

T HE controversial history of allozyme studies: Alternative heritable forms of enzymes, differing in charge or shape, have been known since the 1940s; these may be alleles of one gene (allozymes) or products of distinct but related genes (isozymes). LEWONTIN and HUBBY (1966), finding an unexpected bonanza of allozyme variation in Drosophila, re-cast the existing debate about the evolutionary me...

A systematic use of biofertilizers can improve both the quality a farming system and parameters milk. Some issues related to biofertilization experiments on six farms in Po Valley (NW Italy) involved production milk from dairy cattle fed maize silage or grazed hay produced permanent meadows are reported this paper. Biofertilized was found lower live stem pH by about 2.3%, NIR spectroscopy fores...

Ecosystems across the United States are changing in complex and unpredictable ways analysis of these changes requires coordinated, long-term research. This paper is a product synthesis effort U.S. National Science Foundation funded Long-Term Ecological Research (LTER) network addressing LTER core research area “populations communities.” revealed that each site had at least one compelling “story...

Camellia is a known host of Phytophthora ramorum, the "sudden oak death" pathogen. During 2003-2004, the organism was shipped from California throughout the U.S. on infected nursery stock, leading to a nationwide effort to recover the infected plants. This paper describes the symptoms on Camellia and the relative susceptibility of nine species and four hybrids. Camellias varied widely in suscep...
