Those MIT faculty who mentioned the Harvard project all agreed that it did little 'to improve teaching performance. Mattuck said it might be counterproductive by driving away good professors who might not wish to subject themselves to the. style. typical of the guide's evaluations, while Humanities Chairman Richard Douglass charged that the comments seemed written more for humor and wit than co...

NTEGRITY of the gene in heterozygotes, first inferred from MENDEL'S (1865) I Pisum data and repeatedly corhrmed since in a wide variety of organisms, is regarded as a universal principle in Mendelian heredity. Departures from the law have been reported from time to time, only to prove unfounded, in most instances a t least, on close analysis. The present study is concerned with a seeming except...

We reanalyze the proton decay in the minimal SU(5) SUGRA GUT model. Unlike previous analyses, we take into account a Higgsino dressing diagram of dimension 5 operator with right-handed matter fields (RRRR operator). It is shown that this diagram gives a dominant contribution for p → Kντ over that from LLLL operator, and decay rate of this mode can be comparable with that of p → Kνμ which is dom...

We present results of reanalysis on proton decay in the minimal SU(5) SUSY GUT model. Unlike previous analyses, we take into account a Higgsino dressing diagram of dimension 5 operator with right-handed matter fields (RRRR operator). It is shown that this diagram gives a significant contribution for p → Kντ . Constraints on the colored Higgs mass MC and the sfermion mass mf̃ from SuperKamiokande...

Performance testing methods of boilers in transient operating conditions (start, stop and combustion power modulation sequences) need the combustion rate quantified to allow for the emissions to be quantified. One way of quantifying the combustion rate of a boiler during transient operating conditions is by measuring the flue gas flow rate. The flow conditions in chimneys of single family house...

A novel type of 14-membered cyclic polyphosphine, namely 1,8-diaza-3,6,10,13-tetraphosphacyclotetradecanes 2a–4ahas been synthesized by the condensation of 1,2-bis(phenylphosphino)ethane, formaldehyde and alkylamines (isopropylamine, ethylamine and cyclohexylamine) as a RRRR/SSSS-stereoisomer. The structure of macrocycle 2a was investigated by NMR-spectroscopy and X-ray crystal structure analys...

ABSTRACT Study of parallel manipulators highlights the importance of identifying singular configurations (singularities) during the design, and of avoiding them during the operation; because in these configurations the instantaneous kinematics of the manipulator becomes indeterminate. This paper focuses on the determination of singular configurations of a kinematically redundant 3-RRRR spherica...

The nucleus-localized C2 protein of Tomato yellow leaf curl virus-China (TYLCV-C) is an active suppressor of posttranscriptional gene silencing (PTGS). Consistently, infection with TYLCV-C resulted in PTGS arrest in plants. The C2 protein possesses a functional, arginine-rich nuclear localization signal within the basic amino acid-rich region (17)KVQHRIAKKTTRRRR(31). When expressed from potato ...
