Halbheiten in der Überwindung des Leninismus: Zur Leninkritik des Projekts Klassenanalyse (PKA)

Es ist kein Zufall, daß die ausführliche Leninkritik des PKA: ,,Leninismus - neue Stufe des wissenschaftlichen Sozialismus? Zum Verhältnis von Marxscher Theorie, Klassenanalyse und revolutionärer Taktik bei W. I. Lenin, Westberlin 1972" in der bisher spärlichen Lenindiskussion der westdeutschen sozialistischen Opposition fast völlig ignoriert wurde. Dies liegt bestimmt nicht nur an der rein äußerlich durch den Umfang und die vielen Wiederholungen hervorgerufenen mühseligen Lesbarkeit des Buches, sondern hat seinen eigentlichen Grund in der eigentümlichen politischen Stoßrichtung der Argumentation. Nachdem das PKA die DKP zur „distinkten Arbeiterpartei" erhoben und alle linkskommunistische Kritik am Leninismus als sektiererisch verworfen hat, wird nun doch auf Basis der Marxschen Theorie eine systematische und grundsätzliche Kritik an Lenin, dem Idol des Marxismus-Leninismus, eingeschlossen der DKP, geführt. Dabei kommt das PKA nicht umhin, richtige Elemente der linkskommunistischen, luxemburgianischen, trotzkistischen etc. Positionen aufzunehmen, ohne sie natürlich als solche zu kennzeichnen. Doch bleibt auch die Kritik an Lenin eigentümlich ambivalent: einerseits gelingt es dem PKA in vielen entscheidenden Punkten theoretische und taktische Verkürzungen der Marxsehen Theorie von Lenin nachzuweisen, andererseits wird Lenin nichtsdestoweniger als revolutionäres Vorbild gepriesen. Das PKA gebärdet sich so gleichsam als Wolf im Schafspelz, der aber lieber Schaf als Wolf sein will. Diese Haltung erlaubt es aber der DKP, nach ihrem Belieben die Diskussion mit dem PKA zu führen oder eben auch nicht zu führen, und macht es der nicht an die DKP gebundenen sozialistischen Opposition, die selbst in vielen leninistischen Dogmatisierungen steckt, leicht, das PKA als literarische Repräsentanten der DKP abzutun

Cryogenic infrastructure for Fermilab's ILC vertical cavity test facility

Fermilab is building a Vertical Cavity Test Facility (VCTF) to provide for R&D and pre-production testing of bare 9-cell, 1.3-GHz superconducting RF (SRF) cavities for the International Linear Collider (ILC) program. This facility is located in the existing Industrial Building 1 (IB1) where the Magnet Test Facility (MTF) also resides. Helium and nitrogen cryogenics are shared between the VCTF and MTF including the existing 1500-W at 4.5-K helium refrigerator with vacuum pumping for super-fluid operation (125-W capacity at 2-K). The VCTF is being constructed in multiple phases. The first phase is scheduled for completion in mid 2007, and includes modifications to the IB1 cryogenic infrastructure to allow helium cooling to be directed to either the VCTF or MTF as scheduling demands require. At this stage, the VCTF consists of one Vertical Test Stand (VTS) cryostat for the testing of one cavity in a 2-K helium bath. Planning is underway to provide a total of three Vertical Test Stands at VCTF, each capable of accommodating two cavities. Cryogenic infrastructure improvements necessary to support these additional VCTF test stands include a dedicated ambient temperature vacuum pump, a new helium purification skid, and the addition of helium gas storage. This paper describes the system design and initial cryogenic operation results for the first VCTF phase, and outlines future cryogenic infrastructure upgrade plans for expanding to three Vertical Test Stands

Mu2e Technical Design Report

The Mu2e experiment at Fermilab will search for charged lepton flavor violation via the coherent conversion process mu- N --> e- N with a sensitivity approximately four orders of magnitude better than the current world's best limits for this process. The experiment's sensitivity offers discovery potential over a wide array of new physics models and probes mass scales well beyond the reach of the LHC. We describe herein the preliminary design of the proposed Mu2e experiment. This document was created in partial fulfillment of the requirements necessary to obtain DOE CD-2 approval.Comment: compressed file, 888 pages, 621 figures, 126 tables; full resolution available at http://mu2e.fnal.gov; corrected typo in background summary, Table 3.

Sorafenib increases cytochrome P450 lipid metabolites in patient with hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is a leading cause of cancer death, and medical treatment options are limited. The multikinase inhibitor sorafenib was the first approved drug widely used for systemic therapy in advanced HCC. Sorafenib might affect polyunsaturated fatty acids (PUFA)-derived epoxygenated metabolite levels, as it is also a potent inhibitor of the soluble epoxide hydrolase (sEH), which catalyzes the conversion of cytochrome-P450 (CYP)-derived epoxide metabolites derived from PUFA, such as omega-6 arachidonic acid (AA) and omega-3 docosahexaenoic acid (DHA), into their corresponding dihydroxy metabolites. Experimental studies with AA-derived epoxyeicosatrienoic acids (EETs) have shown that they can promote tumor growth and metastasis, while DHA-derived 19,20-epoxydocosapentaenoic acid (19,20-EDP) was shown to have anti-tumor activity in mice. In this study, we found a significant increase in EET levels in 43 HCC patients treated with sorafenib and a trend towards increased levels of DHA-derived 19,20-EDP. We demonstrate that the effect of sorafenib on CYP- metabolites led to an increase of 19,20-EDP and its dihydroxy metabolite, whereas DHA plasma levels decreased under sorafenib treatment. These data indicate that specific supplementation with DHA could be used to increase levels of the epoxy compound 19,20-EDP with potential anti-tumor activity in HCC patients receiving sorafenib therapy

Field measurement of a Fermilab-built full scale prototype quadrupole magnet for the LHC interaction regions

Superconducting low-beta quadrupole magnets for the interaction regions of the Large Hadron Collider have been developed by the US- LHC Accelerator Project. These 70 mm bore 5.5 m long quadrupoles are intended to operate in superfluid helium at 1.9 K with a nominal field gradient of 215 T/m. Following a series of 2 m long models, a full scale cryostated cold mass has been fabricated and cold tested at Fermilab. Magnetic field measurements of the prototype, including determination of the field axis using a single stretched wire, have been performed. These measurements and comparisons with results from the model magnets as well as field quality and alignment requirements are reported in this paper. (8 refs)
