Teaching in Higher Education: Students’ Deep Learning of Brewing by Labwork
2019
Abstract The amount of theoretical and practical information to be given to students from engineering food specialty is increasingly greater. Within this perspective, it is important to use teaching-learning methods which to develop students’ cognitive ability through the efficient by of them of knowledge acquired at fundamental and specialized disciplines. The article aims to present in an integrated graphical manner the laboratory entitled “Determination of alcoholic concentration of beer by distillation” within the discipline of “Technology and control in the malt and beer industry” that is taught to students in the field of Food Engineering. The integrative approach to the laboratory th…
El ángel y el carnero en el Sacrificio de Isaac. Continuidad y variación en la cultura visual.
2020
La figura del carnero destaca de forma significativa dentro del simbolismo animalístico en el cristianismo. El presente artículo se centra en el estudio diacrónico de las representaciones de dicho animal insertas dentro del tipo iconográfico del Sacrificio de Isaac, cuya fuente literaria es el Génesis 22. El análisis pormenorizado de este elemento significante dentro del pasaje veterotestamentario se torna fundamental a la hora de acudir a los primeros textos realizados por los Padres de la Iglesia, generando en si la aparición del ángel portando el carnero, una variante tipológica dentro del devenir del tipo iconográfico en su continuidad y variación. El objetivo, por tanto, es atender a a…
Analysis of furan in coffee of different provenance by head-space solid phase microextraction gas chromatography-mass spectrometry: effect of brewing…
2009
A simple, sensitive and accurate method for the analysis of furan in roasted coffee has been used based on headspace-solid-phase micro-extraction (HS-SPME) coupled to gas chromatography-mass spectrometry (GC-MS). The extraction was performed using 75-microm carboxen/polydimethylsiloxane fiber. Ionic strength, extraction time and temperature, and desorption time were assessed as the most important parameters affecting the HS-SPME procedure and d(4)-furan was used as the internal standard. The linearity range was in the range 0.0075-0.486 ng g(-1); the LOD and LOQ calculated using the signal-to-noise ratio approach were 0.002 and 0.006 ng g(-1), respectively. The inter- and intra-day precisio…
New development opportunities for the craft brewing segment: the case study of a micro-malthouse
2017
In Italy in the past few years, the number of small breweries penetrating the craft beer sector has grown exponentially. Craft producers intend to give a strong added value and a local character to their production in different ways. One of these is the use of malt derived from small batches of local cereals and pseudo cereals. The aim of this study is the assessment of investment profitability, through a cost-benefit analysis (CBA), for a compact and a modular micro-malting plant in Sicily (Southern Italy). The CBA for a micro-malthouse was carried out considering both installation and operating costs. Net present value (NPV), discounted benefit-cost ratio (DBCR) and internal rate of retur…
Assessment of the influence of counter ions on biosorption of copper cations in brewer's spent grain - Waste product generated during beer brewing pr…
2019
Abstract The influence that conditioning leached ground barley grain (known as “brewer's spent grain” (BSG)) has on the effectiveness of copper cation sorption was analysed. Saturation with counter ions of functional groups present on the grain surface was carried out in hydrochloric acid, sodium hydroxide, sodium and calcium chloride solutions. For comparison, BSG was also conditioned in demineralised water. Spent barley grain is a by-product of the brewing industry which can be used as a biosorbent in the removal of heavy metals from waste water. Emphasis is placed on the effect of competitive sorption of copper and hydrogen cations and the negative influence of a solution alkalinisation …

Molecular organization of a water-insoluble iridium(III) complex in mixed monolayers.
2007
Abstract In this work, organized mixed monolayers containing a cationic water-insoluble iridium(III) complex, Ir-dye, [Ir(ppy)2(tmphen)]PF6, (tmphen = 3,4,7,8-tetramethyl-1,10-phenanthroline, and ppy = 2-phenylpyridine), and an anionic lipid matrix, DMPA, dimyristoyl-phosphatidic acid, with different molar proportions, were formed by the co-spreading method at the air–water interface. The presence of the dye at the interface, as well as the molecular organization of the mixed films, is deduced from surface techniques such as π – A isotherms, Brewster angle microscopy (BAM) and reflection spectroscopy. The results obtained remark the formation of an equimolar mixed film, Ir-dye/DMPA = 1:1. B…
Dual-Emissive Photoluminescent Langmuir−Blodgett Films of Decatungstoeuropate and an Amphiphilic Iridium Complex
2009
Langmuir monolayers and Langmuir-Blodgett (LB) films of the decatungstoeuropate [Eu(W(5)O(18))(2)](9-) (EuW(10)) and the amphiphilic Ir complex 1 have been successfully fabricated by using the adsorption properties of the EuW(10) polyanion dissolved in the aqueous subphase onto a positively charged 1 monolayer at the air-water interface. The compression isotherms and Brewster angle microscopy (BAM) of monolayers of 1 on pure water (1 monolayer) and on a subphase containing 10(-6) M EuW(10) and 10(-3) M NaCl (1/EuW(10) monolayer) have been studied. Infrared and UV-vis spectroscopy of the transferred LB films indicate that EuW(10) and 1 molecules are incorporated within these LB films. X-ray …
The Firstborn of Death: Monotheism and the Mythology of Death in Job 18
2019
AbstractJob 18 depicts the destruction of the wicked as a kind of ambush by “the firstborn of death.” Much of the discussion of this passage has centered on this figure’s identification, and whether one should look primarily to Ugaritic or Mesopotamian mythological traditions for its background. Yet the passage as a whole concludes with a reference to a single “God,” knowledge of whom is determinative for human fate. This raises a basic question concerning the relation between “God” and the “firstborn of death.” Through a close comparison with the Ugaritic Baal Cycle and the Neo-Assyrian Underworld Vision on the one hand, and Job 5 and Deuteronomy 32 on the other, this paper argues that “th…
The Earliest Reference to Israel and Its Possible Archaeological and Historical Background
2017
Manfred Görg proposed to read the name Israel on a broken Egyptian inscriptionäm21687, which is now kept in the storage facilities of the New Museum in Berlin. New research during the last number of years has confirmed this reading, although the writing of the name is different from that of the Merenptah inscription. Some characteristics appear to demonstrate that this inscription is older than the Israel stela of Merenptah and may likely date to the 14th or earlier 13th centurybce. The paper will present some ideas about an earlier beginning of the formation of what is generally called Israel and about the way, how this early Israel came about.
