Aikaterini-Evangelia Mylona,Andreas Bimpilas,Dimitrios Tsimogiannis,Vassiliki Oreopoulou 한국식품과학회 2013 Food Science and Biotechnology Vol.22 No.6

Mavrokountoura, a clone of the Mandilaria grapecultivar, was studied for the first time. The morphologicalcharacteristics and composition of berries were determined,as well as total phenols and tannins in skins, flesh, andseeds. The skin anthocyanins were identified using HPLCMS/MS and quantified using HPLC-DAD. Two mainanthocyanins were identified as malvidin-3-O-glucosideand malvidin-3-O-(6''-p-coumaroyl)-glucoside. One minoranthocyanin was identified as malvidin-3-O-(6''-acetyl)-glucoside. Glycosides of delphinidin, petunidin, andpeonidin were detected in traces. Young Mavrokountourawine was also studied. Extraction of total phenols from thegrape to the young wine amounted to 32%, composingmainly non-tannic phenols. The individual anthocyanincomponents exhibited different extractability values fromthe skin to wine, ranging between 10-94%.

Meningitis-retention syndrome (MRS) is a clinical entity that has recently appeared in the literature. We present the case of a 22-year-old man with fever and headache who, in the course of his hospitalization with a diagnosis of aseptic meningitis, developed acute urinary retention. Fewer than 30 such cases have been described and in several of them, no clear associations with other disorders have been made. In some cases, direct association with viral infection has been proved, and in others, there are indications of an underlying demyelinating condition. To further complicate the issue, various conditions such as Elsberg syndrome and acute disseminated encephalomyelitis, which not only have some similarities but also have some distinct differences, have been placed under the umbrella definition of MRS. In our review, we attempt to address these conditions and better define MRS by establishing diagnostic criteria based on what has thus far been described in the literature.

Ulusoy, B.,Griffin, L.D.,Mylonas, D. 한국색채학회 2017 AIC 2017 Jeju Vol.2017 No.10

We explored Turkish colour naming using an Internet-based colour naming experiment to: a) collect colour names in wide cultural use with their corresponding colour ranges and response times, b) to estimate colour coordinates of centroids of 11 Turkish basic colour terms (BCTs) and to compare them to the 11 English BCTs estimated using the same web-experiment, and c) to establish the English equivalents of the most common Turkish colour names (n>11) based on the distribution of their colour coordinates. Turkish colour names were mostly monolexemic (61%) and 39% of responses were BCTs. The most frequent responses were the BCTs mor (eq. purple), pembe (eq. pink), mavi (eq. blue), yeşil (eq. green) and sarı (eq. yellow) followed by the non-basic turkuaz (eq. turquoise) and lila (eq. lilac). Response time analysis showed that participants responded quicker to sarı, mor, beyaz (eq. white) and siyah (eq. black) than to other terms. Turkish speakers reached consensus (dominance > 50%) for 25 colour names; sarı had the most samples named with consensus followed by mor, bordo (eq. burgundy) and lacivet (eq. navy blue). The comparison between centroids of Turkish and English eleven BCTs showed a very good agreement (CIEDE2000 distances: mean separation=2.5, standard deviation=1.5).

Evaluation of thermal comfort and cooling loads for a multistory building

Lykartsis, Athanasios,B-Jahromi, Ali,Mylona, Anastasia Techno-Press 2017 Advances in energy research Vol.5 No.1

The latest UK Climate Projections (UKCP09) show that mean daily temperatures will increase everywhere in the United Kingdom. This will significantly affect the thermal and energy performance of the current building stock. This study examines an institutional fully glazed building and looks into the changes in the cooling loads and thermal comfort of the occupants during the occupied hours of the non-heating period. Furthermore, it investigates the effect of relative humidity (RH) on thermal comfort. The Design Summer Year (DSY) 2003 for London Heathrow has been used as a baseline for this study and the DSY 2050s High Emissions scenario was used to examine the performance of the building under future weather conditions. Results show a 21% increase of the cooling loads between the two examined scenarios. Thermal comfort appears to be slightly improved during the months of May and September and marginally worsen during the summer months. Results of the simulation show that a relative humidity control at 40% can improve the thermal comfort for 53% of the occupied hours. A comparison of the thermal comfort performance during the hottest week of the year, shows that when the relative humidity control is applied thermal comfort performance of the 2050s is similar or better compared to the thermal comfort performance under the baseline.

Retrofit of a UK residential property to achieve nearly zero energy building standard

Salem, Radwa,Bahadori-Jahromi, Ali,Mylona, Anastasia,Godfrey, Paulina,Cook, Darren Techno-Press 2018 Advances in environmental research Vol.7 No.1

It is currently agreed upon that one of the major challenges in the construction industry is the energy efficiency of existing buildings. The World Meteorological Organisation (WMO) and United Nations (UN) have reported that the concentration of global atmospheric carbon dioxide has increased by an average of 50%, a record speed, from 2015 to 2016. The housing sector contributes to 45% of the UK's carbon emissions. To help tackle some of those issues the recast Energy Performance Building Directive (EBPD) has introduced Nearly Zero Energy Buildings (NZEBs) in the coming years (including buildings that will undergo refurbishment/renovations). This paper will explore the retrofitting of a UK residential dwelling using Thermal Analysis Simulation (TAS, EDSL) software by focusing on building fabric improvements and usage of on-site renewables. The CIBSE Test Reference Year (TRY) weather data has been selected to examine the performance of the building under current and future climate projections. The proposed design variables were finally implemented in the building altogether on TAS. The simulation results showed a reduction in the building's annual energy consumption of $122.64kWh/m^2$ (90.24%). The greatest savings after this were achieved for the annual reduction in carbon emissions and avoided emissions, which were 84.59% and $816.47kg/CO_2$, respectively.

Comparing building performance of supermarkets under future climate change: UK case study

Agha Usama Hasan,Ali Bahadori-Jahromi,Anastasia Mylona,Marco Ferri,Hexin Zhang Techno-Press 2022 Advances in energy research Vol.8 No.1

Focus on climate change and extreme weather conditions has received considerable attention in recent years. Civil engineers are now focusing on designing buildings that are more eco-friendly in the face of climate change. This paper describes the research conducted to assess the impact of future climate change on energy usage and carbon emissions in a typical supermarket at multiple locations across the UK. Locations that were included in the study were London, Manchester, and Southampton. These three cities were compared against their building performance based on their respective climatic conditions. Based on the UK Climatic Projections (UKCP09), a series of energy modelling simulations which were provided by the Chartered Institute of Building Service Engineers (CIBSE) were conducted on future weather years for this investigation. This investigation ascertains and quantifies the annual energy consumption, carbon emissions, cooling, and heating demand of the selected supermarkets at the three locations under various climatic projections and emission scenarios, which further validates annual temperature rise as a result of climatic variation. The data showed a trend of increasing variations across the UK as one moves southwards, with London and Southampton at the higher side of the spectrum followed by Manchester which has the least variability amongst these three cities. This is the first study which investigates impact of the climate change on the UK supermarkets across different regions by using the real case scenarios.

Investigating risk of overheating for school buildings under extreme hot weather conditions

Lykartsis, Athanasios,B-Jahromi, Ali,Mylona, Anastasia Techno-Press 2017 Advances in energy research Vol.5 No.4

This study examines the risk of overheating of a school building, under extreme hot weather conditions, in 14 locations in the United Kingdom using the overheating criteria defined in Building Bulletin 101 (BB101). The building was modelled as naturally ventilated, mechanically ventilated and in mixed mode and was simulated both for the current and the projected weather conditions of the 2050s. Under the current weather conditions, results of the simulations show that when naturally ventilated, the school building fulfils the BB101 criteria only in the areas of Edinburgh and Glasgow. In the simulations of the building as mechanically ventilated and in mixed mode, mechanical cooling was provided in order for the building to comply with the overheating criteria. A comparison of the required cooling loads between the two scenarios shows that application of mixed mode ventilation results in less cooling loads.
