BACKGROUND Fleas are important vectors of human and animal disease, and control measures for protection against their bites and flea-borne diseases are necessary. METHODS The essential oils (EOs) of four native medicinal plants, Ziziphora tenuiore, Myrtus communis, Achillea wilhelmsii and Mentha piperita were isolated by hydrodistillation technique and analyzed by GC-MC. The repellent activit...

Milkfat has the highest price among all the edible oils and fats and plays a significant role in the economics, nutrition and physicochemical properties of milk and milk products. It can be admixed or replaced with less expensive oils and fats of vegetable or animal origins notably palm oils. Blending of edible fat with vegetable oils is a common practice in many countries to improve the physic...

Edible fats and oils are produced by three main industries: oil, margarine and rendering. As margarine manufacture requires only substances that have already undergone refining, the only waste water comes from rinsing the equipment and premises. The oil industry with its different phases of refining uses large quantities of water but could cut its consumption by a more rational organization of ...

Marine oils are important to human nutrition as the major source of docosahexaenoic acid (DHA), a key omega-3 long-chain (≥C20) polyunsaturated fatty acid (n-3 LC-PUFA) that is low or lacking in terrestrial plant or animal oils. The inclusion of fish oil as main source of n-3 LC-PUFA in aquafeeds is mostly limited by the increasing price and decreasing availability. Fish oil replacement with ch...

The developserit, by collaborative study, of a standardised metbod for the determination of the canponent triglycerides of animal and vegetable oils and fats is described. The procedure involves the separation of the triglycerides into groups containing the same number of carbon atoms, the separation being achieved by direct gas-liquid chranatograiy of solutions of the lipids on packed columns ...

We tried to make the relation between the state of nutritional intake and the life span of human beings clear by comparing them internationally. 1. Observing the correlation of nutrition and life span of both advanced and the other nations, the tendency is almost the same with that of the middle and low developed nations. It can be concluded that in any case the more the nutritional intake is, ...

Rising world fuel prices, the growing demand for energy, and concerns about global warming are the key factors driving renewed interest in renewable energy sources and in bioenergy. Nowadays, the world energy demand has increased significantly due to the global industrialization and increase of population. As a result, the current limited reservoirs will soon be depleted at the current rate of ...
