Kadesheinu beMitsvotekha ; The function of the Mitsva

The mitsva reflects one of the most pivotal concepts of Judaism. It sanctifies those who answer its calling, and the Jew and Judaism is unique and “chosen” because of it. In this article we highlight the various ways the mitsvot and Halakha transform us and mold the Jewish personality: (a) by converting the “ought” into a “must”; (b) by transforming daily prosaic acts of man into sacred deeds; (c) by converting simple chronological, linear time into special moments of kedusha. The mitsva involves the total personality - “head, heart and hand” and makes the body equally important with the soul in the service of Hashem. Sanctification is accomplished both through deed and thought. The Torah wants the Jew to build an environment which strengthens his religious values and has designated Erets Yisrael as the most fitting place for kedusha

New addition curing polyimides

In an attempt to improve the thermal-oxidative stability (TOS) of PMR-type polymers, the use of 1,4-phenylenebis (phenylmaleic anhydride) PPMA, was evaluated. Two series of nadic end-capped addition curing polyimides were prepared by imidizing PPMA with either 4,4'-methylene dianiline or p-phenylenediamine. The first resulted in improved solubility and increased resin flow while the latter yielded a compression molded neat resin sample with a T(sub g) of 408 C, close to 70 C higher than PME-15. The performance of these materials in long term weight loss studies was below that of PMR-15, independent of post-cure conditions. These results can be rationalized in terms of the thermal lability of the pendant phenyl groups and the incomplete imidization of the sterically congested PPMA. The preparation of model compounds as well as future research directions are discussed

Guarding the treasure : [Rezension zu:] Tamar Ross, Expanding the Palace of Torah: Orthodoxy and Feminism, Brandeis University Press, Waltham 2004, xxiv + 342 pp.

I. Introduction The early 1970s in the United States was a turbulent, rebellious period – in which all questions were legitimate, certainly on the college campus. As the rabbinic advisor to the Orthodox minyan at Harvard-Radcliffe Hillel, I found myself challenged repeatedly by congregants, colleagues and friends regarding the status of women in Jewish law and ritual. This required me, in turn, to search for honest and appropriate explanations and rationale. This quest has continued to preoccupy me for more than three decades. When I first embarked on this endeavor, I did so with a sense of confidence and commitment. As a “Halakhic Feminist,” I have searched for ways to increase women’s involvement in Jewish spiritual and ritual life, and I remain confident in the inherent viability of the halakhic process. But through it all, my highest commitment has been to the integrity of Halakhah. I firmly believe that without Halakhah as our anchor, we would rapidly lose our direction and raison d’etre.Because of these sensitivities, I picked up Tamar Ross’s recent book “Expanding the Palace of Torah: Orthodoxy and Feminism” with a great deal of excitement and anticipation. The author comes with wonderful credentials: she is an esteemed professor of philosophy, a traditional Jewess, and a highly respected Orthodox feminist. Academically, this extremely analytical, insightful, erudite and welldocumented book turned out to be highly challenging because of its interdisciplinary nature, saturated with new jargon and concepts. But it was by no means disappointing. Indeed, more than 300 pages later, I found myself intellectually edified and stimulated by my newfound understanding of the history, philosophy and theology of feminism. Prof. Ross is quite effective at outlining many of the troubling issues concerning the status of women in Jewish law – issues that every thinking, committed Jew should ponder. As a result, this work has received generally laudatory reviews. Despite all the above, I found the book very unsettling. In her preface (p. xvii), the author indicates that, in addition to scholars of religion and feminism, this book is directed to two other audiences. The first group includes those who have been sensitized by feminism but are desirous of keeping their grip on tradition. The second audience consists of those who are firmly Orthodox, but would like to gain greater insight into what the feminist fuss is all about.5 In short, as the title ofthe book suggests, Prof. Ross attempts to span the divide between Orthodoxy and feminism. Unfortunately, I do not believe she has succeeded in this task, and this essay is an attempt to delineate why

2-Meth­oxy-3,4-diphenyl­phenol

The title compound, C19H16O2, was isolated as the major product after the solid-state photochemical reaction of 2-meth­oxy-4,4-diphenyl­cyclo­hexa-2,5-dienone. The dihedral angles between the central ring and pendant benzene rings are 60.76 (6) and 51.64 (6)°. The O—C vector of the meth­oxy group is almost perpendicular to the plane of the central ring as indicated by the C—C—O—C torsion angle of 94.89 (18)°. Hydrogen-bonded dimers are formed in the crystal structure via O—H⋯O inter­actions. The data were collected at room temperature on a Bruker SMART X2S diffractometer in the automated mode and processed manually thereafter

Tetrahydrophthalic Anhydrides as Addition Curing Polyimide End Caps: Thermal Isomerization of Methylendianiline 3,6-Diphenyltetrahydrophthalic Bisimides

In depth NMR studies confirm that heating a 1:2 mixture of cis, cis, cis 3,6-diphenyltetrahydrophthalic anhydride (end cap 9c) with methylenedianiline at 316 C initially yields the corresponding highly congested cis, cis, cis 3,6-diphenyltetrahydrophthalic bisimide 11, which is converted at this temperature to the observed product, the less hindered trans, cis, trans isomer 12

Health-related quality of life in people with type 2 diabetes participating in the LEADER trial

Aims: To assess health-related quality of life (HRQoL) in people with type 2 diabetes (T2D) participating in the LEADER cardiovascular outcomes trial using the five-dimension European Quality of Life questionnaire (EQ-5D). Materials and methods: The EQ-5D was administered every 12 months in a subset of patients from Canada, Denmark, Germany, Ireland, Italy, Netherlands, Spain, Sweden, the United Kingdom and the United States. We compared changes in utility index scores and visual analogue scale (VAS) scores from baseline to 36 months in participants treated with liraglutide and placebo. We also assessed which complications had the greatest impact on quality of life. Results: At 36 months, less deterioration in EQ-5D utility index score was seen in the liraglutide group (−0.058) than in the placebo group (−0.082; estimated treatment difference [ETD] 0.023, 95% confidence interval [CI] 0.004;0.043; P = 0.020). A smaller decrease in EQ-5D VAS score was also demonstrated in the liraglutide group (−3.51) vs. the placebo group (−5.45; ETD 1.94, 95% CI 0.32;3.57; P = 0.019). The benefits of liraglutide treatment compared with placebo were driven primarily by shifts in the domains of mobility and self-care. The most influential events contributing to poorer HRQoL were stroke, heart failure, malignant neoplasm and confirmed hypoglycaemia. Conclusions: Liraglutide demonstrated a modest but significant benefit in patient-reported health status using the EQ-5D, compared with placebo. This benefit may be of clinical relevance and requires further study
