QTLs for oil content and their relationships to other agronomic traits in an European x Chinese oilseed rape population
(2002-11-25)Rapeseed oil is one of the most important vegetable oils for edible consumption both in China and Europe, while the meal, after extraction of the oil, has a high protein content with well ... -
Quadratische Diophantische Gleichungen über algebraischen Zahlkörpern
(2015-04-23)A search bound for the smallest solution of a quadratic diophantine equation over number fields in at least three variables is established. -
Qualitätssicherungssysteme im türkischen Agribusiness
(2014-12-17)As the implementation of certification systems and other food quality and safety systems has become a strong trend in Turkish agribusiness, there are no comprehensive studies in such field, which is considered of major ... -
Qualitätssicherungssysteme in der Ernährungsbranche
(2006-01-16)Current policy trends and changing consumer expectations have resulted in a variety of private initiatives searching for new approaches to ensure quality assurance in the food sector. A ... -
Quality Assessment and Quality Improvement for UML Models
(2011-03-01)Models defined using the UML are nowadays a common part of software documentation, specification and sometimes even implementation. However, there is a broad variety in how UML is used. ... -
Quality Assurance of Test Specifications for Reactive Systems
(2010-08-20)Extensive testing of modern communicating systems often involves large and complex test suites that need to be maintained throughout the life cycle of the tested systems. For this purpose, ... -
Quantendynamik von S>N2-Reaktionen
(2007-03-05)This thesis presents quantum mechanical investigations of the mechanism involved in nucleophilic bimolecular substitution reactions (SN2 reactions). The SN2 mechanism i importan both for application in a wide ... -
Quantenmechanik zwischen Regularität und Chaos

Quantifizierung der Feinwurzeln von Bäumen durch elektrische Verfahren
(2015-04-23)The quantification especially of fine roots of trees creates some difficulty because, contrary to the aboveground parts of the tree, roots are not readily visible. In recent years electrical methods have been developed for ... -
Quantifizierung des Luftvolumenstromes in frei gelüfteten Rinderställen mit Hilfe der Kompartimentalisierungsmethode zur Bestimmung umweltrelevanter Emissionsmassenströme
(2001-01-10)The assessment of airflow volume becomes increasingly important in estimating the environmental impact of airborne stable emissions. In contrast to mechanically ventilated stables the amount ... -
Quantifying stand structure and structural complexity along a management gradient in temperate forests
(2020-10-01)The structure and structural complexity of forests influence many important characteristics of forest ecosystems, as well as their functions and services, such as ecosystem stability, maintenance of biodiversity and carbon ... -
Quantifying the impact of forest management intensity and tree species diversity on individual tree shape and three-dimensional stand structure
(2020-11-04)The three-dimensional distribution of trees and their crowns is an essential characteristic of forest ecosystems that is directly related to several ecosystem functions and services. Silvicultural interventions modify the ... -
Quantifying the uncertainty caused by sampling, modeling, and field measurements in the estimation of AGB with information of the national forest inventory in Durango, Mexico
(2020-05-20)Aboveground biomass (AGB) is related to the carbon content of the forest and forest carbon is a core variable for contemporary forest management and policy decisions. A credible and precise estimate of AGB is a prerequisite ... -
Quantifying three-dimensional stand structure and its relationship with forest management and microclimate in temperate forest ecosystems
(2018-02-01)Summary Forest management modifies the spatial structure of forest ecosystems, which is considered to be relevant for habitat availability and biodiversity as well as several ecosystem processes and functions. Contrary ... -
Quantifying three-dimensional stand structure of European beech forests along a management gradient
(2022-04-26)Forest structure is of functional importance for ecosystem stability and resilience, as well as for numerous other ecosystem functions and services. In this context, a high structural complexity can have a positive effect ... -
Quantitative Analyse dynamischer nichtlinearer Panelmodelle
(2002-11-20)Dynamic nonlinear panel models are estimated on the first 14 waves (waves A to N) of the German Socio-Economic Panel to test (among other things) for state dependence effects in male ... -
Quantitative Analyses on the Effects of the EU Sugar Market Policy
(2023-05-23)The sugar market has long been excluded from the systematic reform process of the EU’s Common Agricultural Policy started with the MacSharry reform in 1992. While the markets of most other agricultural products were ... -
Quantitative analysis of protein-protein interactions governing TASK-1/TASK-3 intracellular transport
(2016-07-27)The transport of the K+-channels TASK-1 and TASK-3 to the cell surface is regulated by protein-protein interactions with either the COPI vesicle coat, or members of the phosphoadaptor protein family 14-3-3. Interactions ... -
Quantitative Analysis of Synaptic Vesicle Membrane Trafficking
(2018-08-02)The fate of synaptic vesicles upon fusion to the plasma membrane is unclear. Two models have been proposed: vesicle proteins either stay clustered in patches, thus retaining the molecular identity of individual vesicles, ... -
