Block transfers

Spiramycin is a macrolide that inhibits protein biosynthesis by blocking transfer of the aminoacyl-rRNA along the ribosome in a unique organelle of the parasite, termed apicoplast. The apicoplast is a remnant of a secondary endosymbiosis of a red algae and is only found in the phylum sporozoa.

XGA Acronym for Extended Graphics Array. XGA is only available as a micro channel architecture expansion board it is not available in ISA or EISA form. XGA supports resolution of 1024 horizontal pixels by 768 vertical pixels with 256 colors, as well as a VGA mode of 640 pixels by 480 pixels with 65,536 colors, and like the 8514/A, XGA is interlaced. XGA is optimized for use with graphical user interfaces, and instead of being very good at drawing lines, it is a bit-block transfer device designed to move blocks of bits Hke windows or dialog boxes. 

Chloramphenicol and florfenicol act by binding to the 50S ribosomal subunit and blocking transfer RNA, inhibiting bacterial protein synthesis. They are considered bacteriostatic, but the MBCs of florfenicol for some respiratory pathogens are low enough to consider it bactericidal. 

While the previous sections mainly dealt with layers that contain electroactive species, layers that serve to block electron and ion transport between an electrode and a solution are also of interest. These can have practical applications, for example, to prevent corrosion of the surface or to serve as electrical insulators. Electrochemical methods are useful in establishing how well such layers block transfer to the surface and, as discussed in Section 14.5.2, can be used to study the distance dependence of electron transfer. 

A possible transfer of mannose from retinyl mannosyl phosphate to polypeptide was first indicated by the studies of Maestri and De Luca (1973), though these did not prove that retinyl mannosyl phosphate was the mannosyl donor. In a more detailed analysis Rosso etaL (1977) used a radioactive label largely free of dolichyl mannosyl phosphate in a cell-free system and obtained a clear-cut incorporation of mannose from retinyl mannosyl phosphate into a substance with the solubility properties of protein and which was labile to proteolysis. Some free mannose, its 1-phosphate and retinyl mannosyl phosphate were also present at the end of the incubation, but no large mannolipid was detected. Dolichy CJmannosyl phosphate did not give any transfer of [ C] mannose to protein and further support for a distinctive retinol pathway came from the effects of EDTA. This totally failed to block transfer from retinyl [ mannosyl phosphate, under conditions where block...

The basic idea of this approach is simple. The typical CP block transfers magnetization from the protons to the carbons ( C) as discussed in Section 3.4. Flowever, not aU C nuclei will have obtained the full enhancement within the duration of a single CP block which is chosen relatively short compared to ( T p/(cp duration of the relax-... 

Frequently, consecutive memory locations must be transferred over the bus. Moving the address once and incrementing a counter on the memory are more efficient than sending the address each time, especially if the bus is multiplexed. Block transfers are supported by the most... 

Parallel buses such as Futurebus-l- have a small market compared to the PC board market. Interconnection of PCs with fast links is the modern trend to get more power and more reliability (uninterruptible systems). Inside the PC, the need for a bus for interconnecting the essential peripherals has disappeared since the serial, parallel, and disk ports are available on the processor itself. With USB and Firewire, the only other need for an extension bus is for memory access and ultrafast transactions with the graphic board. New solutions will have to appear over the next 10 years. They will be based on very fast synchronous block transfers, large caches being available on every device. The width of the bus will determine the cost of the solution 128-bit buses will be proposed, but the huge market will be for bit and byte serial buses.
