Urban and peri-urban lands can be an important source of food production for localised and sustainable food systems, however, their soils can be of poor quality, degraded or damaged by anthropic activities, and little is known about their suitability

In the last years, the study of vitamin D has raised due to the increase in the incidence of people who have deficient levels of this vitamin. Few foods contain vitamin D3 naturally, the main source of obtaining the ultraviolet (UV)solar radiation, w

The variability of total ozone and UV radiation from Total Ozone Mapping Spectrometer (TOMS) measurements is analyzed as a function of polar vortex occurrences over the southern subpolar regions during the 1997–2005 period. The analysis of vortex o

Photoallergic contact dermatitis (PACD) to oxybenzone was reported for the first time in 1980. Oxybenzone is the most common photoallergen in the United States and Canada and the fourth most common .in Europe. There are no studies or data on the prev

In this work we predict the maximum amplitude, its time of occurrence, and the total length of Solar Cycle 24 by linear regression to the curvature (second derivative) at the preceding minimum of a smoothed version of the sunspots time series. We cha

This paper deals with the spectral dependence and time variability of Angstrom wavelength exponent scaling law (α), which is the spectral varying slope of the logarithmic relationship between aerosol optical depths (τ) and the wavelength (λ). It i

Two nonlinear methods are employed for the prediction of the maximum amplitude for solar cycle 23 and its declining behavior. First, a new heuristic method based on the second derivative of the (conveniently smoothed) sunspot data is proposed. The cu

The two-centre atomic orbital close-coupling expansion method is used to study the excitation and ionization processes in collisions of protons with metastable hydrogen H(2s). The excitation cross sections to n=3 and 4 and the averaged dipole moments

We have extended our previous work on electron-capture total cross sections for the Li3++Li(2s) system by considering a larger molecular basis and taking into account the electron-translation effects. In the present paper we also include differential

Cross sections for electron capture from the n=2 excited states of atomic hydrogen in collisions with protons and alpha particles are calculated using the semiclassical close-coupling method where the time-dependent wavefunction is expanded in terms
