Present and future potential of plant-derived products to control arthropods of veterinary and medical significance [PDF]
The use of synthetic pesticides and repellents to target pests of veterinary and medical significance is becoming increasingly problematic. One alternative approach employs the bioactive attributes of plant-derived products (PDPs). These are particularly

EFFECT OF RIPENESS AND DRYING OF HOPS ON THE ESSENTIAL OIL [PDF]
The examination of undried Fuggles hops picked at intervals throughout the ripening period revealed that the total oil content of the samples rose throughout ripening, the production of hydrocarbons far exceeding that of the oxygenated compounds.

Cellulosic materials as biopolymers and supercritical CO2as a green process: chemistry and applications [PDF]
In this review, we describe the use of supercritical CO2 (scCO2) in several cellulose applications. The focus is on different technologies that either exist or are expected to emerge in the near future.

DIFFERENCES IN UTILISATION OF THE ESSENTIAL OIL OF HOPS DURING THE PRODUCTION OF DRY-HOPPED AND LATE-HOPPED BEERS [PDF]
Late-hopped and dry-hopped beers were prepared and their lipophilic constituents extracted using Amberlite XAD-2 resin. Examination of the volatile constituents by GC-MS confirmed that most of the hop oil added towards the end of wort boiling is lost by evaporation.

Evaluation of original historical clones of hops (Humulus lupulus L.)
The aim of this study was to compare yield and technological parameters of Czech historical hop clones, which were grown in our current climatic conditions. The highest yields from the selected original hop clones were found in “Úštěcký smetaňák” (1.93 t/
