    Effects of once-weekly semaglutide on appetite, energy intake, control of eating, food preference and body weight in subjects with obesity.

    AIM: To investigate the mechanism of action for body weight loss with semaglutide. MATERIALS AND METHODS: This randomised, double-blind, placebo-controlled, two-period crossover trial investigated the effects of 12 weeks treatment with once-weekly subcutaneous semaglutide, dose-escalated to 1.0 mg, in 30 subjects with obesity. Ad libitum energy intake, ratings of appetite, thirst, nausea and well-being, control of eating, food preference, resting metabolic rate, body weight and body composition were assessed. RESULTS: After a standardised breakfast, semaglutide, compared with placebo, led to a lower ad libitum energy intake during lunch (-1255 kJ; P < 0.0001), and during the subsequent evening meal (P = 0.0401) and snacks (P = 0.0034), resulting in a 24% reduction in total energy intake across all ad libitum meals throughout the day (-3036 kJ; P < 0.0001). Fasting overall appetite suppression scores were improved with semaglutide versus placebo, while nausea ratings were similar. Semaglutide was associated with less hunger and food cravings, better control of eating and a lower preference for high-fat foods. Resting metabolic rate, adjusted for lean body mass, did not differ between treatments. Semaglutide led to a reduction from baseline in mean body weight of 5.0 kg, predominantly from body fat mass. CONCLUSION: After 12 weeks' treatment, ad libitum energy intake was substantially lower with semaglutide versus placebo with a corresponding loss of body weight observed with semaglutide. In addition to reduced energy intake, likely mechanisms for semaglutide-induced weight loss included less appetite and food cravings, better control of eating and lower relative preference for fatty, energy-dense foods

    Furrow application of insecticide as a method of controlling wireworms in potato land

    Three methods of applying insecticides for the control of the wireworm, &lt;i&gt;Agriotes obscurus&lt;/i&gt; L.. were tested using fonofos and terbufos. Most treatments gave significantly more marketable tubers than the control. The furrow treatment gave more consistent results than broadcast or side-dress and, at 1.1 or 2.2 kg a.i/ha, gave control equal to, or better than, the broadcast treatment at 5.6 kg a.i./ha. Analyses by gas chromatography using a flame photometric detector for residues in potatoes grown in treated soil showed residues to be less than 0.02 ppm

    Heat Capacity in Magnetic and Electric Fields Near the Ferroelectric Transition in Tri-Glycine Sulfate

    Specific-heat measurements are reported near the Curie temperature (TCT_C~= 320 K) on tri-glycine sulfate. Measurements were made on crystals whose surfaces were either non-grounded or short-circuited, and were carried out in magnetic fields up to 9 T and electric fields up to 220 V/cm. In non-grounded crystals we find that the shape of the specific-heat anomaly near TCT_C is thermally broadened. However, the anomaly changes to the characteristic sharp λ\lambda-shape expected for a continuous transition with the application of either a magnetic field or an electric field. In crystals whose surfaces were short-circuited with gold, the characteristic λ\lambda-shape appeared in the absence of an external field. This effect enabled a determination of the critical exponents above and below TCT_C, and may be understood on the basis that the surface charge originating from the pyroelectric coefficient, dP/dTdP/dT, behaves as if shorted by external magnetic or electric fields.Comment: 4 Pages, 4 Figures.

    Efficacy of insecticides against tuber flea beetles, wireworms and aphids in potatoes

    Soil-incorporated and foliar-applied insecticides, alone and in combination, were tested in silt loam to control tuber flea beetle, Epitrix tuberis Gent., the green peach aphid, Myzus persicae (Sulz.) and the wireworm Agriotes obscurus (L.) Most soil-incorporated band treatments did not give adequate protection from tuber flea beetles. However, supplemental foliar applications, July 15 and 30 and August 15, reduced the percentage unmarketable tubers to 13% under a heavy infestation in 1977 and to 0% in a lighter infestation in 1978. Fonofos, broadcast and soil-incorporated, gave the best control of wireworms and of a light infestation of tuber flea beetles. Methamidophos was the best aphicid

    Self-recovery from disasters: an interdisciplinary perspective

    Get PDF
    This working paper presents the findings from a pilot research project that investigated how disaster-affected households in low- and middle-income countries rebuild their homes in situations where little or no support is available from humanitarian agencies. The project was an interdisciplinary collaboration involving social scientists, geoscientists, structural engineers and humanitarian practitioners. The work was broad in scope. It investigated households’ self-recovery trajectories and the wide range of technical, environmental, institutional and socioeconomic factors influencing them over time. It also considered how safer construction practices can be more effectively integrated into humanitarian shelter responses

    Dopant-induced crossover from 1D to 3D charge transport in conjugated polymers

    Get PDF
    The interplay between inter- and intra-chain charge transport in bulk polythiophene in the hopping regime has been clarified by studying the conductivity as a function of frequency (up to 3 THz), temperature and doping level. We present a model which quantitatively explains the observed crossover from quasi-one-dimensional transport to three-dimensional hopping conduction with increasing doping level. At high frequencies the conductivity is dominated by charge transport on one-dimensional conducting chains.Comment: 4 pages, 2 figure
