ABSTRACT The location of surface brightness maxima (e.g. apocentre and pericentre glow) in eccentric debris discs are often used to infer the underlying orbits dust planetesimals that comprise disc. However, there is a misconception have higher densities at thus necessarily exhibit glow long wavelengths. This arises from expectation slower velocities lead ‘pile up’ dust, which fails account for...
Abstract Artificial light at night is increasing globally, interfering with both sensory ecology and temporal rhythms of organisms, from zooplankton to mammals. This interference can change the behaviour affected hence compromise viability their populations. Limiting use artificial may mitigate these negative effects. Accordingly, we investigated whether duration affects sexual signalling in fe...
In this process after making proper chamber to produce plasma in d.c. Glow regime and readiness of samples and doing microhardness and PIXE analyzes, samples nitriding began in different conditions. The hardness changes and the depth of hardened layer of 321, 316 and 304 steels are studied as a function of discharge parameters [8, 9]. The plasma was produced using a mixture of N2 and H2 gases...
Lithium tetraborate nanoparticles were synthesized by combustion method. The shape and size of nanoparticles were determined by scanning electron microscopy (SEM). X-ray diffraction pattern (XRD) confirmed the formation of lithium tetraborate nanocrystals. Thermoluminescence (TL) glow curve of the produced nanoparticles following irradiating with gamma radiation demonstrates five overlapping gl...
This paper investigates the determinants of time and money gifts. We first develop a behavioural model which accounts for both types of donations, as well as for decisions about domestic and market hours of work. We then investigate the issue empirically, using survey data for Italy. Results suggest that, according to the theoretical predictions, proxies for “warm glow”, reputational concerns a...
