It allows an efficiency analysis and systematic optimization of a single power train as well as a comparison of different power train concepts. The methodology is applied to a wheeled excavator. To ensure a realistic power demand in the simulation, a rule-based operator model is developed.Technology: general issuesbicsscAntriebssystemeBaggerBewertungsmethodikEnergieeffizienzenergy efficiencyevaluation methodologyexcavatorFahrermodellmobile machinesMobile Arbeitsmaschinenoperator modelpower trainssimulationSimulationTechnology: general issuesSturm Christophauth1332348BOOK9910346779003321Bewertung der Energieeffizienz von Antriebssystemen mobiler Arbeitsmaschinen am Beispiel Bagger3040870UNINA04656nam 2200949z- 450 991055712420332120210501(CKB)5400000000040812(oapen)https://directory.doabooks.org/handle/20.500.12854/68359(oapen)doab68359(EXLCZ)99540000000004081220202105d2021 |y 0engurmn|---annantxtrdacontentcrdamediacrrdacarrierChromosome Manipulation for Plant Breeding PurposesBasel, SwitzerlandMDPI - Multidisciplinary Digital Publishing Institute20211 online resource (138 p.)3-0365-0024-3 3-0365-0025-1 The ability to exploit the potential of wild relatives carrying beneficial traits is a major goal in breeding programs. However, it relies on the possibility of the chromosomes from the crop and wild species in interspecific crosses to recognize, associate, and undergo crossover formation during meiosis, the cellular process responsible for producing gametes with half the genetic content of their parent cells. Unfortunately, in most cases, a barrier exists preventing successful hybridization between the wild and crop chromosomes. Understanding the mechanisms controlling chromosome associations during meiosis are of great interest in plant breeding and will allow chromosome manipulation to introduce genetic variability from related species into a crop. In addition to interspecific hybrids, other materials, such as natural and synthetic polyploids and introgression lines derived from allopolyploids, among others, are powerful tools in the framework of plant breeding. For example, an extra pair of alien chromosomes in the full genome complement of a crop species has been frequently used as a first step to access genetic variation from the secondary gene pool in breeding programs. In addition, such introgression lines are also pivotal in the study of interspecific genetic interactions, in the chromosomal location of genetic markers, and in the study of chromosome structure and behavior in somatic and meiotic cells. Contained in this Special Issue are accounts of original research, including new tools to identify chromosome introgressions and the development and characterization of introgression lines and interspecific hybrids carrying desirable agronomic traits for plant breeding purposes. Also included are reviews about the chromosome engineering of tropical cash crops and the effect of chromosome structure on chromosome associations and recombination during meiosis to allow chromosome manipulation in the framework of plant breeding.Biology, life sciencesbicsscResearch & information: generalbicssc5R dissection lineAegilopsalien chromosomeanatomyaneuploidybarleycacaocentric breakschromosome engineeringchromosome fusionchromosome pairingchromosome rearrangementscitruscoffeecrossover distributioncytogeneticsflow cytometryfluorescence in situ hybridizationgrain colourhistogenic layerHordeum chilenseintrogressionmeiosismeiotic recombinationmini-satellitenon-homologous recombinationpapayaPCR markersPCR-based markersphysical mappolyploidypolyploidy breedingRobertsonian translocationsryestarchstripe rustsynthetic biologytandem repeatstelosomic chromosomestriticaleTriticeaetritordeumtropical cash cropswaxy proteinswheatwheat bread-making genewheat introgressionwheat qualitywild barleyBiology, life sciencesResearch & information: generalPrieto Pilaredt317569Prieto PilarothBOOK9910557124203321Chromosome Manipulation for Plant Breeding Purposes3038147UNINA
