Food-grade argan oil supplementation in molasses enhances fermentative performance and antioxidant defenses of active dry wine yeast
2015
The tolerance of the yeast Saccharomyces cerevisiae to desiccation is important for the use of this microorganism in the wine industry, since active dry yeast (ADY) is routinely used as starter for must fermentations. Both biomass propagation and dehydration cause cellular oxidative stress, therefore negatively affecting yeast performance. Protective treatments against oxidative damage, such as natural antioxidants, may have important biotechnological implications. In this study we analysed the antioxidant capacity of pure chemical compounds (quercetin, ascorbic acid, caffeic acid, oleic acid, and glutathione) added to molasses during biomass propagation, and we determine several oxidative …
Powers and Fundamental Rights in Cyber Security
2015
Protection of privacy and confidential communications are crucial fundamental rights in cyber security. The protection of privacy and confidential communications are twofold in the meaning that active security steps in communications may require interference with confidential communications. The detection and profiling of potential threats may raise suspects on innocent participants of communications. The NCSC-FI inside the Communications Authority has the initial task and powers to monitor the cyber security. The bill for the Code of Information Society introduces new obligations for information security and preparation for emergency situations. If new powers will be granted to authorities…
Calculation of the chemical potential and the activity coefficient of two layers of CO2 adsorbed on a graphite surface.
2014
We study the adsorption of carbon dioxide at a graphite surface using the new Small System Method, and find that for the temperature range between 300 K and 550 K most relevant for CO2 separation; adsorption takes place in two distinct thermodynamic layers defined according to Gibbs. We calculate the chemical potential and the activity coefficient of both layers directly from the simulations. Based on thermodynamic relations, the entropy and enthalpy of the CO2 adsorbed layers are also obtained. Their values indicate that there is a trade-off between entropy and enthalpy when a molecule chooses for one of the two layers. The first layer is a densely packed monolayer of relatively constant e…
Acute effects of cold pack on mechanical properties of the quadriceps muscle in healthy subjects.
2012
Purpose: To examine the effects of local cooling on mechanical properties of the quadriceps muscle in healthy subjects. Subjects: Thirty-nine healthy subjects (27 women, 12 men, mean age 39, range 20e62) volunteered. Methods: A cold gel pack was applied to the quadriceps muscle for 20 min. Properties were quantified by analyzing the frequency (tension), decrement (elasticity) and stiffness of damped oscillations and the compliance of the muscle before, immediately after and after 15-min after cooling. Results: The largest responses immediately after cooling were seen in the oscillation decrement parameter, 7.9 (3.7e12.1) %, and in the compliance parameter, � 7.5 (� 9.8 to � 5.3) %. Response…
Effects of Infrared-A Irradiation on Skin: Discrepancies in Published Data Highlight the Need for an Exact Consideration of Physical and Photobiologi…
2010
Skin exposure to infrared (IR) radiation should be limited in terms of irradiance, exposure time and frequency in order to avoid acute or chronic damage. Recommendations aimed at protecting humans from the risks of skin exposure to IR (e.g. ICNIRP, ACGIH) are only defined in terms of acute effects (e.g. heat pain and cardiovascular collapse), whereas the actual exposure conditions (e.g. spectral distribution, exposure geometry, frequency and number of exposures, thermal exchange with the environment, metabolic energy production and regulatory responses) are not taken into consideration. Since the IR component of solar radiation reaching the Earth's surface is mainly IR-A, and considering th…
Resistance Training Acutely Impairs Agility and Spike-Specific Performance Measures in Collegiate Female Volleyball Players Returning from the Off-Se…
2020
This study examined the acute effects of resistance training (RT) on volleyball-specific performance. Sixteen female volleyball players undertook their initial, pre-season RT bout. Countermovement jump (CMJ), delayed onset of muscle soreness (DOMS), and sport-specific performances (i.e., run-up jump, agility, and spiking speed and accuracy) were measured before, 24 (T24), and 48 (T48) hours after RT. A significant increase in DOMS was observed at T24 and T48 (~207.6% ±
Mickiewiczowska głębia "miejsca". Wertykalny charakter Soplicowa
2020
The shape of a circle, with its midpoint or centre, is one of the spatial images lying at the basis of many of the lyrical poems written by Adam Mickiewicz, including The Vision, Defend Me from Myself..., The Akkerman Steppes, Spin Love…, To Flee with My Love onto a Leaf [Leaves]... The motif of a circular shape with a clearly defined centre also appears in Master Thaddeus, and in Forefathers’ Eve. Mickiewicz the poet structures his works around the imagery of a circle and its centre to convey metaphorically what is of value to Mickiewicz the man. His ‘centric’ thinking puts the poet in the centre of an ontological, metaphysical vision of the cosmos, right in the centre, at the very core of…
INTELLECTUAL FILTERS AND THE DISSEMINATION OF SMITHIANISM AN INTRODUCTORY NOTE
2020
Adfam Smith’s thought reached every corner of the world in a short lapse of time but made its entrance through institutional, cultural, linguistic, religious and political filters. These filters are not neutral and affected the reading, understanding and use of Smithian ideas. I chose the keyword ‘intellectual filters’ to denote all of the contextual elements whose influence determines whether and how a foreign paradigm penetrates a country and creates its effects.
