The Stanley Kunitz-Stockmal Collection

Stanley Kunitz was born in Worcester in 1905 and shortly after college moved away. Beginning in the 1960s, he returned to give poetry readings and to receive honors. Kunitz searched unsuccessfully for his boyhood home on Woodford Street. Then, in 1985, he came to Worcester for the week-long Stanley Kunitz Poetry Festival in honor of his 80th birthday and on the last day of the festival, Kunitz decided to try once more to find the house on Woodford Street. Greg and Carol Stockmal, who had bought the house in 1979, found Kunitz and his entourage standing in front of their home. They invited everyone in, and when Kunitz mentioned a pear tree he and his mother had planted in the backyard, Greg told him one still grew there, and it produced abundant fruit. The 20 year friendship between the Stockmals and Kunitz and his wife, artist/poet Elise Asher, began on that day. The Stanley Kunitz-Stockmal Collection consists of materials collected by Greg and Carol Stockmal and includes: correspondence from Kunitz to the Stockmals; books signed and inscribed by Kunitz and his wife, poet/artist Elise Asher; audiovisual material on Kunitz; photographs of Kunitz and the Stockmals; and newspaper clippings and other articles on Kunitz collected by the Stockmals

Mapping logistics practice using the product life cycle

The dynamic nature of today\u27s global economy places a premium on a firm\u27s ability to anticipate and to respond to customer needs as well as changing competitive pressures. Within this environment, developing a successful logistics strategy can be critical to the firm\u27s long-term competitive success. This paper looks at the potential for using the product life cycle (PLC) as a strategic framework in the logistics strategy planning process. Results of an empirical study that investigated the appropriate use of 43 logistics techniques across PLC stages are reported. The implementation status of the various logistics techniques is also considered

Intersection of two signalling pathways: extracellular nucleotides regulate pollen germination and pollen tube growth via nitric oxide

Plant and animal cells release or secrete ATP by various mechanisms, and this activity allows extracellular ATP to serve as a signalling molecule. Recent reports suggest that extracellular ATP induces plant responses ranging from increased cytosolic calcium to changes in auxin transport, xenobiotic resistance, pollen germination, and growth. Although calcium has been identified as a secondary messenger for the extracellular ATP signal, other parts of this signal transduction chain remain unknown. Increasing the extracellular concentration of ATPγS, a poorly-hydrolysable ATP analogue, inhibited both pollen germination and pollen tube elongation, while the addition of AMPS had no effect. Because pollen tube elongation is also sensitive to nitric oxide, this raised the possibility that a connection exists between the two pathways. Four approaches were used to test whether the germination and growth effects of extracellular ATPγS were transduced via nitric oxide. The results showed that increases in extracellular ATPγS induced increases in cellular nitric oxide, chemical agonists of the nitric oxide signalling pathway lowered the threshold of extracellular ATPγS that inhibits pollen germination, an antagonist of guanylate cyclase, which can inhibit some nitric oxide signalling pathways, blocked the ATPγS-induced inhibition of both pollen germination and pollen tube elongation, and the effects of applied ATPγS were blocked in nia1nia2 mutants, which have diminished NO production. The concurrence of these four data sets support the conclusion that the suppression of pollen germination and pollen tube elongation by extracellular nucleotides is mediated in part via the nitric oxide signalling pathway

Recent Advances Clarifying the Structure and Function of Plant Apyrases (Nucleoside Triphosphate Diphosphohydrolases).

Studies implicating an important role for apyrase (NTPDase) enzymes in plant growth and development began appearing in the literature more than three decades ago. After early studies primarily in potato, Arabidopsis and legumes, especially important discoveries that advanced an understanding of the biochemistry, structure and function of these enzymes have been published in the last half-dozen years, revealing that they carry out key functions in diverse other plants. These recent discoveries about plant apyrases include, among others, novel findings on its crystal structures, its biochemistry, its roles in plant stress responses and its induction of major changes in gene expression when its expression is suppressed or enhanced. This review will describe and discuss these recent advances and the major questions about plant apyrases that remain unanswered

Project Columbiad: Reestablishment of human presence on the Moon

In response to the Report of the Advisory Committee on the future of the U.S. Space Program and a request from NASA's Exploration Office, the MIT Hunsaker Aerospace Corporation (HAC) conducted a feasibility study, known as Project Columbiad, on reestablishing human presence on the Moon before the year 2000. The mission criteria established were to transport a four person crew to the lunar surface at any latitude and back to Earth with a 14-28 day stay on the lunar surface. Safety followed by cost of the Columbiad Mission were the top level priorities of HAC. The resulting design has a precursor mission that emplaces the required surface payloads before the piloted mission arrives. Both the precursor and piloted missions require two National Launch System (NLS) launches. Both the precursor and piloted missions have an Earth orbit rendezvous (EOR) with a direct transit to the Moon post-EOR. The piloted mission returns to Earth via a direct transit. Included among the surface payloads preemplaced are a habitat, solar power plant (including fuel cells for the lunar night), lunar rover, and mecanisms used to cover the habitat with regolith (lunar soil) in order to protect the crew members from severe solar flare radiation
