Throughout his career, Leon Osterweil has made significant contributions that have impacted the research and state-of-the-practice on development environments. Initially his focus was on programming environments, mostly addressing issues needed to support his work in program analysis. Later his focus expanded to software lifecycle issues, such as flexible component interaction models, efficient...

Interactions between root-knot nematodes and viruses were recently reviewed by Taylor (4). Compared to virus-free cowpea (vigna sinensis Endl.), cowpea mosaic virus-infected plants formed fewer galls on roots in response to infection by Meloidogyne incognita (Kofoid and White) Chitwood (2). On the other hand, tobacco plants (Nicotiana tabacum L.) infected with tobacco ringspot virus (TRSV) and ...

There has only been one clinically confirmed case of terbinafine resistance in dermatophytes, where six sequential Trichophyton rubrum isolates from the same patient were found to be resistant to terbinafine and cross-resistant to other squalene epoxidase (SE) inhibitors. Microsomal SE activity from these resistant isolates was insensitive to terbinafine, suggesting a target-based mechanism of ...

Trends in Abortion Attitudes The GSS has carefully maintained the same wording and sequence of questions from year to year to avoid introducing context changes into the time series.* Respondents are asked whether a woman should be able to obtain a legal abortion for a series of reasons, beginning with “if there is a strong chance of defect in the baby” and ending with “if the woman wants it for...

from Chakaravarthy [3]: Given a program and two variables p and q, the goal of points­to analysis is to check if p can point to q in some execution of the program. This well­ studied problem plays a crucial role in compiler optimization. The problem is known to be un­ decidable when dynamic memory is allowed. But the result is known only when variables are al­ lowed to be structures. We extend ...

During the Pleistocene, numerous species of equids were found in North and South America, Asia, and Africa. Of these, only seven or eight species remain today (depending on whether the domestic and Przewalski’s horse are counted as one or two species). Although the fossil record of Equidae is one of the classic examples of the evolutionary process, there are still many aspects of the evolution ...

A rack of order n is a binary operation B on a set X of cardinality n, such that right multiplication is an automorphism. More precisely, (X,B) is a rack provided that the map x 7→ x B y is a bijection for all y ∈ X, and (x B y) B z = (x B z) B (y B z) for all x, y, z ∈ X. The paper provides upper and lower bounds of the form 2cn 2 on the number of isomorphism classes of racks of order n. Simil...

These proceedings contain the manuscripts from the Second International Congress on Seafood Technology on Sustainable, Innovative and Healthy Seafood held in Anchorage, the United States of America from 10 to 13 May 2010. The University of Alaska organized the meeting in collaboration with the FAO Fisheries and Aquaculture Department. The congress reviewed developments related to: • internation...
