Between “full moon and summer solstice”. The quest for transcendence in the poetry of Andrzej Busza
2019
The article is an attempt to describe the poet’s vision of human destiny, history and transcendence. Analysing poems from two poetry volumes I endeavour to present Busza’s philosophy. The poet notes and appreciates science and scientifi c achievements as well as civilisational development, although he realises that they may be dangerous for human spirituality and potentially lead to catastrophe.
Seabird migration strategies: Flight budgets, diel activity patterns and lunar influence
2021
Every year, billions of birds undertake extensive migrations between breeding and nonbreeding areas, facing challenges that require behavioural adjustments, particularly to flight timing and duration. Such adjustments in daily activity patterns and the influence of extrinsic factors (e.g., environmental conditions, moonlight) have received much more research attention in terrestrial than marine migrants. Taking advantage of the widespread deployment in recent decades of combined light-level geolocator-immersion loggers, we investigated diel organisation and influence of the moon on flight activities during the non-breeding season of 21 migrant seabird species from a wide taxonomic range (6 …
Estudios estructurales y funcionales de dUTPasas, una amplia familia de enzimas metabólicas con funciones reguladoras
2023
El dUTP es el nucleótido no canónico mayoritario en la célula. Su errónea incorporación en el ADN dispara los sistemas de reparación, los cuales pueden causar la muerte celular por una actuación ininterrumpida. Con el objetivo de prevenir esta situación, y conocida la incapacidad de las ADN polimerasas de distinguir entre el dTTP y el dUTP, las células poseen las proteínas dUTPasas (Duts), capaces de degradar este nucleótido no canónico y, en consecuencia, aumentar la ratio dTTP/dUTP en el pool de nucleótidos celular. A parte de la hidrólisis del dUTP, las Duts poseen otras funciones moonlighting, entre las cuales destaca la capacidad de Duts de fagos de Staphylococcus aureus de interaccion…

Spectroscopic Detection and Structure of Hydroxidooxidosulfur (HOSO) Radical, An Important Intermediate in the Chemistry of Sulfur-Bearing Compounds
2013
The rotational spectrum of hydroxidooxidosulfur, HOSO, an intermediate of particular interest in the combustion of sulfur-rich fuels, has been determined to high accuracy from gas-phase measurements. Detection of specific isotopic species using isotopically enriched gases suggests that HOSO is formed in our discharge nozzle via the reaction H + SO2 (+M) → HOSO (+M). A precise experimental r0 geometry has also been derived from the isotopic analysis; HOSO has a cis configuration, but the subtle structural question of its planarity remains unresolved. From the derived spectroscopic constants, in situ and remote sensing for this fundamental radical can now be undertaken in a variety of environ…

The Religion of Ammon
2015
The Ammonites, a people living east of the Jordan River, were neighbors of the ancient Israelites. The Old Testament (1 Kings, 11,5; 2 Kings, 23,13) and probably an inscription from the citadel of Amman mention Milkom as the supreme God of the Ammonites. Most Ammonite names did not contain the name of their national god, but used a more generic divine name, ’El. We don’t know if the name: ’El refers to the Canaanite god or to a local manifestation of this deity. Ammonites also worshiped other deities (i.e. ‘Astarte, ‘Anat, Ba‘al, Hadad/’Adad, Qos, Samas, YHWH and Yerah). A number of limestone statues and clay figurines of bearded individuals wearing an atef-crown could be Ammonite monarchs …
¿Qué explica la Física sobre la influencia de la Luna en la Tierra? Una propuesta de enseñanza
2021
En este trabajo se abordan ideas pseudocientíficas en torno a la influencia de la Luna en nuestro planeta. Para ello se analiza si los libros de Física de Bachillerato y de Educación Superior tratan la influencia de la gravedad de la Luna en la Tierra y cómo lo hacen. Para el análisis se utiliza una muestra de 17 libros de textos de Física de Bachillerato y 17 utilizados en cursos de ciencia e ingeniería (13 de Física, 2 de Óptica y 2 de Astronomía) de distintos años de publicación. Los resultados revelan la escasa atención que prestan estos libros a los temas relacionados con la física de la Luna y su influencia sobre nuestro planeta, así como un enfoque descontextualizado de la enseñanza …
Calibration of the Lunar Orbital X-ray Fluorescence Imaging Spectrometer (LOXIA) of Chang'E-1 satellite at INAF-OAPA
2007
The Lunar Orbital X-ray Fluorescence Imaging Spectrometer (LOXIA) designed and constructed at the Institute of High Energy Physics of the Chinese Academy of Sciences to perform chemical composition analysis of the Moon surface will operate on-board the Chang'E-1 mission, the first Chinese lunar spacecraft to be launched in 2007. We report the main results of the calibration measurements that we have performed using the X-ray beamline of the XACT facility of INAFOsservatorio Astronomico di Palermo G.S. Vaiana to determine the quantum efficiency of the XRS detector in the soft X-rays as a function of photon energy and angle of incidence.
Conflicts between touristic recreational activities and breeding shearwaters: short-term effect of artificial light and sound on chick weight
2018
Human disturbances are increasingly becoming a conservation concern for many populations of colonial seabirds. Colonially reproducing species are particularly vulnerable to localised disturbances because detrimental elements can simultaneously affect the entire population. Studies of petrels and shearwaters have shown that light pollution, in particular, can be harmful for both fledglings and adults, but little is known of the way such anthropogenic elements affect the quality of parental care at the nest. Chick provisioning in petrels and shearwaters occurs exclusively at night and is also negatively correlated with the amount of moonlight. We tested the hypothesis that high-intensity ligh…
