The study describes the household items and furnishings of the court through the pottery and glass finds recovered from the cesspit of the royal palace at Visegrád, alongside an examination of the assemblage’s composition and its place of origin. A comparison of the mid-14th and late 15th century finds sheds light on the changes that took place during this period.
Abstract
The recycling of greywater for non-potable water applications, such as toilet flushing or irrigation, is a potential solution to reduce potable water consumption. To estimate the quality of raw greywater samples, we measured several physical, chemical and biological parameters. We used Hygiene Monitor test kits to determine microbiological presence in the samples. The greywater samples showed a high variability for all the measured parameters. In general, we found that greywater sources had lightly alkaline character with a considerable inorganic and organic content. About half of the analyzed samples can be characterized as highly contaminated water source with organic substance. The average BOD5 and DOC values of greywater samples were 429 ± 410 mg l−1 and 341 ± 348 mg l−1. The samples showed high similarity concerning the total plate counts parameter (range from 5 to 6 log10 cfu ml−1). Among the three greywater sources, the samples from dish sources showed the lowest coliform content (3.9 log10 cfu ml−1) and the bath samples were contaminated with coliforms to the highest degree (4.9 log10 cfu ml−1). The results of E. coli contamination tests proved that all greywater sources can be contaminated with pathogen bacteria, consequently the treatment before reuse of greywater is indispensable.
Comparison of Hungarianground red paprika volatiles of known origin (identical to cultivated varietiesgrown in Kalocsa, Hungary) and provenance has been performed following simultaneous distillation-extraction sample preparation. After polar phase capillary gas-chromatography, mass spectrometric identification of as many compounds as possible was carried out to precisely describe the aroma profile of the cultivars. For conceptualizing the results a data evaluation and interpretation method has been elaborated considering the component ratios that are much more characteristic of the cultivars than the absolute amounts themselves. Relative intensity interpretation of the peak areas (y-axis) and Programmed Temperature Retention Index (x-axis) measurement resulted in aromagrams individually characteristic of the cultivated varieties. In an identification experiment the cultivars have been recognized successfully by the graphic visualization of the results called aroma-spectra (by analogy to mass spectrometry) method.
The use of continuous-flow chemistry has shown to be an important tool in improving API manufacture. In the present paper, we report the use of continuous-flow reactors in the synthesis of the bicyclic side chain of antiretroviral Darunavir.
