    Notes: Leaves of Stephania japonica and Smilax australis were characterized in situ on the coast of north-eastern New South Wales, Australia, where they were growing naturally in three different light environments: deep shade, in the understory of an open Eucalyptus forest where they received frequent sunflecks of high intensity, and in an exposed site receiving full sunlight. In deep shade the xanthophyll cycle remained epoxidized during the day and the vast majority of absorbed light was utilized for photosynthesis. In the exposed site both deepoxidation and epoxidation of the xanthophyll cycle and changes in the level of xanthophyll-dependent thermal energy dissipation largely tracked the diurnal changes in photon flux density (PFD). In the understory the xanthophyll cycle became largely deepoxidized to zeaxanthin and antheraxanthin upon exposure of the leaves to the first high intensity sunfleck and this high level of deepoxidation was maintained throughout the day both during and between subsequent sunflecks. In contrast, thermal energy dissipation activity, and the efficiency of photosystem II, fluctuated rapidly in response to the changes in incident PFD. These findings suggest a fine level of control over the engagement of zeaxanthin and antheraxanthin in energy dissipation activity, presumably through rapid changes in thylakoid acidification, such that they became rapidly engaged for photoprotection during the sunflecks and rapidly disengaged upon return to low light when continued engagement might limit carbon gain.

    The Psychiatric Care Satisfaction Questionnaire: a reliability and validity study (1999)

    Notes: Abstract Patient satisfaction can be a useful marker in evaluating the quality of psychiatric care. However, this form of measurement has been hampered by the lack of attention paid to the psychometric properties of instruments devised. The Psychiatric Care Satisfaction Questionnaire (PCSQ) was developed and tests of acceptability, validity and reliability were undertaken using 52 inpatients. Content validity was assessed by surveying psychiatrists, other mental health professionals, MIND workers and patient groups. Thirty-six (67.9%) of all mental health professionals felt that the questionnaire was a useful measure of patients' satisfaction with their care, and many comments also suggested high consensual validity. In terms of content validity, responses from patient groups indicated that the majority (63.6%) felt it to be a useful measure of patient satisfaction and 70.5% felt all the areas covered were important. Concurrent and criterion validity were also good, with high correlations with existing scales and with those on a section being significantly less satisfied on the PCSQ (F = 13.3, P = 0.0004). Test-retest reliability was adequate (Cohen's κ 0.48–0.80) and the internal consistency of the PCSQ was good, at 0.82 (Cronbach's α). The PCSQ performed well in all aspects of validity and reliability, indicating that it has good psychometric properties and can be a useful tool for measuring patient satisfaction. However, there remains the need to analyse more closely the concept of satisfaction and its determinants.

    Notes: Summary In a study of men aged 59 to 70 years plasma glucose levels 30 min and 2 h after a 75-g glucose load were inversely related to birthweight. To determine whether there are similar relations at a younger age the 30-min plasma glucose levels of 40 men aged 21 years, who were born in one hospital in the United Kingdom, were measured. Lower birthweight was associated with higher 30-min plasma glucose levels. This trend was independent of gestational age, and current body mass, height and social class.

    Topics: Biology
    Notes: Abstract We report the cloning and characterization of two lectin genes from Medicago truncatula, designated Mtlec1 and Mtlec2. The two genes show a high degree of homology and apparently belong to a small multigene family. Mtlec1 appears to encode a functional lectin with 277 amino acids, whereas Mtlec2 is probably non-functional, since a frameshift mutation (insertion of two nucleotides) leads to premature translation termination after only 98 amino acids. The deduced amino acid sequence of the polypeptide MtLEC1 suggests that this lectin is a metalloprotein with Glc/Man specificity.

    Ultimate capacity of blast loaded structures common to chemical plants (1992)

    Notes: There has been a great deal of investment in development of design criteria and design and construction of heavily reinforced, blast-resistant control rooms. This remains the best option for protective construction against severe blast loading experienced close in to a vapor cloud or other explosion hazard. However, most structures encountered at chemical plants and contemplated for future construction are conventional steel frame, metal clad buildings. In this paper we look closely at the response of such buildings to explosion loads and their ability to undergo large deformations without structural failure. The types of structural elements evaluated include metal decking of various gauge and shape along with a variety of girt and purlin sections. Building frames or bents are also evaluated, although the date base for these is much more limited. The work is based on observations made during investigations of large explosion accidents along with analytical predictions and test measurements. To conclude, we offer specific design criteria and connection recommendations for enhancing the overall strength of a building through the use of conventional components in unconventional construction.
