Birds may respond differently depending on the character of the predator's attack and these split-second decisions were studied using a model merlin (Falco columbarius) that attacked feeding blue tits (Parus caeruleus) from two different attack angles in two different speeds. Under attack, take-off is crucial for survival and even minor mistakes in initial escape response can have devastating consequences. Lind, Johan Kaby, Ulrika Jakobsson, Svenīird mortality is heavily affected by birds of prey. Split-second escape decisions in blue tits (Parus caeruleus) The existing software was modified to allow for processing of different AVE/SESAME data set types including satellite surface and radar data. All AVE/SESAME data sets in random access format was processed to allow developed software to access the entire AVE/SESAME data base. Software documentation was provided for existing AVE/SESAME programs underlining functional flow charts and interacting questions. Software was converted to AVE/SESAME software systems and interfaced with existing graphics hardware/software available on the REEDA System. Software was developed to graphically display the AVE/SESAME data in the convention normally used by severe storm researchers. The AVE/SESAME software was modified to incorporate the random access file input and to interface with new graphics hardware/software now available on the REEDA system. A random access file system for the AVE storm data was designed, tested, and implemented. The REEDA system software was modified and improved to process the AVE-SESAME severe storm data. This paper also provided a new genetic method to obtain C5-oxo-avermectin B-producing strain. This is consistent with that aveD and aveF are in a transcription unit. This revealed that both aveD and aveF were not expressed in the disruptant. Shaking flask experiments and HPLC analysis showed that the disruptant produced only four components, which were C5-oxo-avermectin B1a, B1b, B2a, B2b as identified by UV, IR, NMR, and MS. Disruptants were confirmed by Southern blotting. The plasmid was inserted into the chromosome by homogenous recombination between partial aveD gene in the plasmid and aveD in the chromosome. Recombinant plasmid pCZ2(pKC1139::475 bp aveD) was used for aveD gene disruption in Streptomyces avermitilis 76-9. Comments are included on the functional morphology of the terminal genitalia. in relation to the ventral sucker), a smaller ventral sucker and smaller eggs. It is differentiated in detail from its congeners, but differs mainly in having a substantially larger phallus (e.g. sp., is a microphallid from the intestine of the snail kite Rostrhamus sociabilis ( Vieillot). Kostadinova, Aneta Vaucher, Claude Gibson, David IĪ new species in the little-known digenean fauna of Paraguayan birds is described in detail, especially in relation to its terminal genitalia. (Digenea: Microphallidae) from Rostrhamus sociabilis ( Vieillot) ( Aves: Accipitridae) in Paraguay. To this end, I was fortunate to obtain the contribution of certain leading scientists in the field of cell separation, people who in their pioneer ing work have struggled with the particular problems involved in separating living cells and in some way have won.Megalophallus deblocki n. Therefore, the purpose of this open-end treatise is to acquaint the reader with some of the basic principles, instrumentation, and procedures pres ently in practice at various laboratories around the world and to present some typical applications of each technique to particular biological prob lems. A number of good techniques exist based either on the physical or biological properties of the cells, and these have produced some valuable results. However, the development of such useful methods is still in its infancy. , transfusion) purposes are some of the pressing areas where immediate practical benefits can be obtained by applying cell separation techniques. Clinical diag nosis of diseased states and use of isolated cells for therapeutic (e. Unless cells exhibiting different functions and stages of differ entiation are separated from one another, it will be exceedingly difficult to study some of the molecular mechanisms involved in cell recognition, specialization, interactions, cytotoxicity, and transformation. Presently, the need for methods involving separation, identification, and characterization of different kinds of cells is amply realized among immu nologists, hematologists, cell biologists, clinical pathologists, and cancer researchers.
