Development of energy-saving innovative hydraulic mortars reusing spent coffee ground for applications in construction

2023

This paper reports the development of green bio-composite mortars, obtained reusing spent coffee ground (SCG), an agri-food residue, in the light of the Circular Economy approach. This process can boost the sustainability in Construction and proposes an alternative to SCG disposal in landfill, potentially dangerous to humans and the environment. For the first time, specimens were produced and compared using different blends of conventional hydraulic binders (ordinary Portland cement and natural hydraulic lime); SCG partially substituted sand (up to 15 wt.%, with a 2.5% increment) for the aggregate mix. The manufacturing process was performed at ambient conditions (20°C, 65% RH) resulting hi…

Normal pressures and frictional tractions on shallow conical hopper walls after concentric filling: Predictions and experiments

2013

Author's version of an article in the journal: Chemical Engineering Science. Also available from the publisher at: http://dx.doi.org/10.1016/j.ces.2012.11.028 A silo with a shallow hopper is designed to achieve the required silo capacity when the headroom available is limited, provided that the issue of segregation of stored particulate solids is not a problem. Several analytical models have been proposed to try to predict the design loads for such shallow silo hoppers to guarantee their structural integrity. In this study, a novel finite element analysis has been conducted to explore the development of pressures and tractions on the wall of a full scale shallow hopper when it is filled wit…

Der Stoffwechsel verschiedener Carbons�uren durch Milchs�urebakterien

1984

The anaerobic metabolism of citrate, fumarate, gluconate, malate, 2-oxoglutarate and pyruvate by 137 strains of 23 species of lactic acid bacteria was investigated. The bacteria were from various sources (plant material, meat and dairy products, dough and wine) and belonged to the genera Lactobacillus, Leuconostoc, Pediococcus, and Streptococcus. The ability of metabolize the acids was determined by thin layer chromatography or by enzymatic analysis after growth of the strains in a glucose-containing medium. All strains metabolized pyruvate and only 12 mainly heterofermentative strains were malate negative. These strains were also unable to decompose citrate. This acid was fermented by 23 s…

In vitrobioaccessibility of iron and zinc in fortified fruit beverages

2009

Summary Iron and zinc bioaccessibility was estimated in the in vitro gastrointestinal digests of six different fortified fruit beverages (Fb) containing iron and/or zinc and/or skimmed milk (M). Solubility values can be used to establish trends in relative bioavailability of iron and zinc, as the first stage towards mineral bioavailability comprises solubility in the intestinal tract. FbFe, FbFeM and FbFeZnM samples showed iron bioaccessibility above 88%, differing (P < 0.05) from those of FbFeZn (53%). In turn, FbZn, FbFeZn and FbZnM samples presented higher zinc bioaccessibility (above 68%), differing (P < 0.05) from those of FbFeZnM (48%). The presence of milk-derived caseinophosphopepti…

Inductively coupled plasma optical emission spectroscopy determination of trace element composition of argan oil.

2011

A methodology based on inductively coupled plasma optical emission spectroscopy (ICP-OES) after microwave assisted acid digestion has been developed to determine the trace element content of Moroccan argan oil. Limit of detection values equal or lower than few mg/kg were obtained for all elements under study. To assure the accuracy of the whole procedure, recovery studies were carried out on argan oil samples spiked at different concentration levels from 10 to 200 µg/L. Quantitative average recovery values were obtained for all elements evaluated, demonstrating the suitability of this methodology for the determination of trace elements in argan oil samples. Aluminum, calcium, chromium, iro…

Combined use of modified atmosphere packaging and high pressure to extend the shelf-life of raw poultry sausage

2014

International audience; The contribution of modified atmosphere packaging (MAP) in extending the shelf-life of high-pressure treated raw poultry sausages was examined by considering microbial and oxidative stability (TBARs) aspects. Raw poultry sausages packaged under air or modified atmosphere (50% CO2–50% N2) were pressurized at 500 MPa during 5 min at a maximum temperature of 10.5 °C, subsequently allowed to refrigerated storage during 22 days. During storage, samples were tested at time intervals for headspace gas composition, pH, TBARs, Aerobic Mesophilic Counts (AMC) and Lactic Acid Bacteria (LAB) counts. The high pressure treatment could represent an efficient means of extending the …

Hazard analysis and critical control points in deep-fat frying

2002

The Hazard Analysis and Critical Control Point (HACCP) system was applied to sunflower oils used for frying in nineteen university restaurants. Guidelines for implementation that include training personnel, flow diagram, identifying hazards, controlling hazards at critical control points (CCP's), monitoring CCP's and measure of action for exceeding limit were developed. Polar compounds were used as a measure for deteriorated sunflower oil and the values obtained from university restaurants before and after personnel training and implementation of HACCP were determined. Implementation of the guidelines produced an improvement in the quality of the frying process, and all establishments reduc…

Sport sponsorship in Finland: the case study of FC JJK Jyväskylä

2013

This paper seeks to analyse sport sponsorship in Finland via using the case study of Football Club JJK Jyväskylä from the Finnish Premier League. The results of a master’s thesis conducted on FC JJK fans’ sponsor awareness and sponsor orientation is presented. This research has provided implications to the management of the club, such as how to increase sponsorship efficiency, how to benefit from applying sponsorship alignment as well as relationship marketing. In order to successfully implement the study, an on­line survey, interviews, and participant observation was utilised. In addition, statistical data were obtained from the club. It has been concluded that JJK fans’ sponsor awareness …

Dealing with a Trauma Burdened Past: between Remembering and Forgetting

2017

Recognition that societies will not be able to build a future as long as they do not face the ‘demons of the past’ has become a kind of universal truth over the last decades of the 20th Century (Gibney et al., 2008, p. 1). This view, though challenging and ambiguous, is reflected in the globally present attempts to improve or rebuild relations within and between different communities at the domestic and international level. The question concerning, on the one hand, the essence and most essential elements and, on the other hand, the instruments and the limitations of rebuilding relations, as well as the political implications of those processes have become the broad area of interest and the …
