The filamentous fungus Neurospora crassa is a long-studied eukaryotic microbial system amenable to heterologous expression of native and foreign proteins. However, relatively few highly tunable promoters have been developed for this species. In this study, we compare the tcu-1 and nit-6 promoters for controlled expression of a GFP reporter gene in N. crassa. Although the copper-regulated tcu-1 ...

thunderstorm is one of the most dangerous phenomena in aviation because the greatest number weather hazards such as icing, turbulence, wind shear, lightning hail are combined in one single source, the thunderstorm. spatial characteristics of thunderstorms which can be associated with irreparable outcomes are known by most of the forecasters. tornadoes, microbursts, very strong winds and flash f...

One of the world's greatest plant collections has won a top heritage award at a time when it is highlighting with a tree-top walkway the need to study the forest canopy which is one of the most crucial but least understood habitats.

The design innovations in the IBM 3803 Tape Control Unit and the IBM 3420 Magnetic Tape Unit are discussed. The new design concepts include a full readback parity check, a system of microprogram control that obtains high operating rates through overlap of channel control and motion control functions, a new phase-error detection system, a modified dual-density recording feature and a new interfa...

We use magnetic thin film hard/non/soft-magnetic trilayer systems to probe the nature of the hard–soft phase interaction and the role played by dipolar fields in onedimensional (d) magnetic systems. We have systematically A.J. Zambano ( ) · H. Oguchi · I.

Of all the phenomena in the atmosphere, there is none that exceeds the thunderstorm in beauty as it builds up from a small detached cumulus into a towering and awe-inspiring cumulonimbus. However, aviators treat thunderstorms with reverence for they are associated with hail, wind shear and turbulence, squalls and at times heavy precipitation. Thunderstorms during the hot and dry pre-monsoon sea...

In this study, the distributions of certain parts of speech, especially auxiliaries, is investigated. Using the definition of the h-point, we define the thematic concentration of the text and introduce the concentration unit tcu.
