We begin with the simplest possible introduction to supergravity, and then discuss its spin 3/2 stress tensor. Next, we discuss boundary conditions on fields and boundary actions for N = 1 supergravity. Finally, we discuss new boundary contributions to the mass and central charge of monopoles in N = 4 super Yang-Mills theory. All models are in 3+1 dimensions. YITP-SB-06-21

salinity affects plant growth by the osmotic stress of salt around the roots as well as by toxicity caused by excessive accumulation of salt in leaves. the study of photosynthetic traits as a rapid and non-destructive tool demonstrates the great potential for improving plant productivity and stress tolerance. a pot experiment was carried out to investigate short-term effects of osmotic stress (...

Solid-Liquid-Gas equilibrium of poly-(ε-caprolactone) – carbon dioxide systems at high pressure has been determined by visual determination of the first melting point using a static apparatus. Measurements have been performed with poly-(ε-caprolactones) of three different molecular weights: 4000 g/mol, 10000 g/mol and 25000 g/mol. The determined SLG equilibrium lines show a temperature maximum ...

Experiments were performed in a cylindrical 0.14 m diameter bubble column with a metal perforated plate. Air and aqueous solutions of glycerol with viscosity 1–22 mPa s were the phases. Gas holdup was measured and plotted against the gas flow rate. The critical point where the homogeneous–heterogeneous regime transition begins was determined by the drift-flux plot of the primary data. The homog...

We investigated the photosynthetic limitations occurring during dehydration and rehydration of Xerophyta humilis, a poikilochlorophyllous resurrection plant, and whether volatile and non-volatile isoprenoids might be involved in desiccation tolerance. Photosynthesis declined rapidly after dehydration below 85% relative water content (RWC). Raising intercellular CO(2) concentrations during desi...

Increasing levels of greenhouse gases lead to ocean warming, which affects a range marine organisms. Corals live in narrow temperature and become stressed when the temperatures change. Bleaching occurs exceeds coral’s threshold, can be severe this is combined with other stressors such as light. In order understand how light affect corals their physiological responses photosynthetic performance,...

The remaining carbon budgets compatible with limiting global warming to 1.5 or 2 °C above preindustrial levels are shrinking rapidly. An already firmly anticipated, but highly controversial measure mitigate this challenge is the large-scale implementation of negative emissions, removing dioxide from atmosphere. Many currently considered emission technologies (NET) based on natural photosynthesi...

Introduction: Most asteroids for which porosities have been inferred have porosities ranging from 20% to >50%, with a mean of ~30% porosity [1]. Porosity significantly affects the physical properties of rocks, including the strength, thermal conductivity, seismic velocity, and dielectric permeability. Some asteroids have high enough porosities to affect their internal structure, gravitational f...

PURPOSE The porcelain fused to gold has been widely used as a restoration both with the natural esthetics of the porcelain and durability and marginal fit of metal casting. However, recently, due to the continuous rise in the price of gold, an interest towards materials to replace gold alloy is getting higher. This study compared the bond strength of porcelain to millingable palladium-silver (P...
