In the perpendicular recording, the magnetic polarity is perpendicular to the media surface and can be read with a GMR sensor similar to the sensor used in LMR. In this case, the media is effectively situated within the head gap, potentially relaxing many limits on both head and media design experienced in longitudinal recording.

A review of the evolution of filter media design will provide a better insight into the differences between media systems. The slow sand filter was developed in... 

Many dual-media designs have been used. However, the media sizes have been kept relatively constant — that is, 1.0-mm coal and 0.43-mm sand with the depths of each material varied. As can be noted from Fig. 2, much of the fine sand has been removed, and the filter is much coarser. Headloss characteristics have been improved, and longer filter runs should be expected.

A preparatory step following extraction of a sample media designed to remove components that may interfere with subsequent analytical measurements. 

Today, the baculoviras expression vector system represents a well-established technology for routine pilot production of small to medium quantities of desired product proteins, mainly for research purposes. The characteristics of BEVS, including culture media design, virus production and quantification as well as large-scale cell culture, have been extensively studied during the past decade, and this has resulted in...

Among the strategies used for increasing the produetion of medicinal componnds it can be mentioned the media design, elicitation and the genetic engineering approach. 

An additional strategy for improving alkaloid yield and productivities of in vitro cultures is by the appropriate media design [68]. It is important to consider that the biosynthetic pathways that lead to the accumulation of secondary metabolites are complex and sometimes are not fully elucidated [6, 23]. Also, the regulation of these pathways is frequently unknown and these features are needed in order to perform a rational media design [68]. However, it is generally accepted that sucrose is the carbon source preferentially used. The increase of carbon source up to certain levels favors growth and secondary metabolites production. However, further increases may derive in catabolite repression [68]. 

In conclusion, for the optimization of secondary metabolites production by media design several considerations should be taken into account. In many cases it is necessary to develop a growth medium and a production one. In the first case, it is necessary to select a basal medium and optimize it for the maximal biomass production.
