Dieta w życiu ascetycznym Ojców pustyni

The Diet in the ascetic life of Desert Fathers - Summary The author discusses in his article the diet practiced in the hermit environmentof the Egyptian monks, in the period which is especially known to us from theconserved monastic sources, that is, the 4th and 5th centuries, in particular of theApophthegmata Patrum and writings of Evagrius Ponticus. First, the author of thearticle outlines an ascetic perspective in the life and the environment of: St. Anthonythe Hermit, St. Pachomius and the hermits of the settlements in Nitria, Kellia andScetis. Then, he discusses in details elements of the hermit diet. Finally, he presentsthe theological and moral premises of their fasting practices

Hardness of water analysis at the Grotowice intake situated near Opole

The determination of raw water hardness subsequently treated and used for domestic water supplies is a useful parameter to characterize the present total dissolved solids as well as for calculation dosages for lime-soda softening application. Because water hardness concentrations have not been proven to be health related, the final achieved level is mainly an economic function. To identify existing trends, the changes in water hardness in Grotowice intake for the years 1999-2017 have been analysed. The obtained results indicate clearly that the water hardness in three wells shows a slight downward trend, but on the other hand, one trend is rising in another direction

Volumetric incorporation of NV diamond emitters in nanostructured F2 glass magneto-optical fiber probes

Integration of optically active diamond particles with glass fibers is a powerful method of scaling diamond's magnetic sensing functionality. We propose a novel approach for the integration of diamond particles containing nitrogen-vacancy centers directly into the fiber core. The core is fabricated by stacking the preform from 790 soft glass canes, drawn from a single rod dip-coated with submicron diamond particles suspended in isopropyl alcohol. This enables manual control over the distribution of nanoscale features, here – the diamond particles across the optical fiber core. We verify this by mapping the diamond distribution in the core using confocal microscopy. The particles are separated longitudinally by 12–29 μm, while in the transverse plane a separation of approximately 1.5–2.2 μm is observed, corresponding to the individual cane diameter in the final fiber, and without significant agglomeration. The fiber's magnetic sensitivity is confirmed in optically detected magnetic resonance recorded with a coiled, 60-cm-long fiber sample with readout contrast of 1.3% limited by microwave antenna coverage. Moreover, magnetic-field dependence of the NV─ fluorescence intensity is demonstrated in the absence of microwaves, allowing magnetometric applications with a large (from 0 to 35 mT) B-field dynamic range
