BACKGROUND To investigate the effect of environmental factors such as light and shade on essential oil yield and morphological traits of Moroccan Myrtus communis, a chemometric study was conducted on 20 individuals growing under two contrasting light environments. RESULTS The study of individual's parameters by principal component analysis has shown that essential oil yield, altitude, and lea...

Herbal water is referred to the liquid obtained from the distillation of medicinal plants. Different parts of plants, such as flowers, fruits, leaves, seeds and roots have long been used to produce herbal waters. Herbal waters are used as dietary supplements and alternative medicine and are commonly used for flavoring in baking. Previous studies focused on the non-volatile constituents of herbs...

The purpose of food packaging is to preserve the quality and safety of the food it contains from the time of manufacture to the time it is used by the consumer. Recently, the demand for safe and high quality foods, as well as changes in consumer preferences have led to the development of innovative and novel approaches in food packaging technology. One such development is the active food packag...

Background:  Cisplatin has cytotoxic effects through free radical generation. Reports indicate that various members of Pinaceae family may have antioxidant properties. In this study we investigated the cytoprotective effects of needle volatile oil and bark extract of Pinus eldarica in hepatoma G2 (HepG2) cell line.  Methods: Using the maceration technique, we obtained the ethanolic extract of ...

Kinetic and fluid dynamic constraints on deepseated magma migration rates suggest ascent velocities in the range 10 to 30 m/s, 10 -1 to 10m/s and 10 -2 to 5m/s for kimberlitic, garnet peridotite-bearing and spinel peridotite-bearing alkalic magmas. These rates virtually demand translithospheric magma transport by a fracture as opposed to diapiric mechanism. The hypothesis that volatile exsoluti...

2.0 What are the challenges? There are two groups of ‘biogas generating’ organisms available within an Anaerobic Digestion process: acetoclastic methanogens and hydrogenotrophic methanogens. Food waste has a high nitrogen content due to the high protein component. During anaerobic digestion this generates a high level of ammonia which is toxic to the acetoclastic methanogens. Whilst biogas prod...
