Morphological and Genetic Diversity of Sea Buckthorn (Hippophae rhamnoides L.) in the Karakoram Mountains of Northern Pakistan
(2018-07-30)
Sea buckthorn (Hippophae rhamnoides L.) is a dioecious, wind-pollinated shrub growing in Eurasia including the Karakoram Mountains of Pakistan (Gilgit-Baltistan territory). Contrary to the situation in other countries, in Pakistan this species is heavily underutilized. Moreover, a striking diversity of berry colors and shapes in Pakistan raises the question: which varieties might be more suitable for different national and international markets? Therefore, both morphological and genetic diversity of sea buckthorn ...

Estimation of Vegetable Crop Parameter by Multi-temporal UAV-Borne Images
(2018-05-22)
3D point cloud analysis of imagery collected by unmanned aerial vehicles (UAV) has been shown to be a valuable tool for estimation of crop phenotypic traits, such as plant height, in several species. Spatial information about these phenotypic traits can be used to derive information about other important crop characteristics, like fresh biomass yield, which could not be derived directly from the point clouds. Previous approaches have often only considered single date measurements using a single point cloud derived ...

Schlussbericht zum Projekt SimCast – Simulationsgestützte Prognose der Dauer von Logistikprozessen
(2018)
Für den kundenindividuellen Anlagenbau in der Unikat- und Kleinserienfertigung sind die termingerechte Fertigstellung, Lieferung und Inbetriebnahme einer Anlage entscheidende Wettbewerbsfaktoren. Bei der Planung neuer Projekte kann das bisher aus Projekten erworbene Wissen allerdings nicht 1:1 in ein neues Projekt übertragen werden, da die Parameter und die Dauer der Montage- und Logistikprozesse von dem jeweils zu montierenden Bauteil abhängig sind. Aus diesem Grund wird diese Prozessdauer heute nur grob abgeschätzt; ...

How to tackle alveolar milk ejection problems during milking in dam rearing? Influence of different stimuli in the parlour and effects of half-day compared to free contact
(2018-07)
Dissertation Katharina Zipp 2018: Wie können Alveolarmilch-Ejektionsstörungen beim Melken bei muttergebundener Kälberaufzucht reduziert werden? Einfluss verschiedener Stimuli im Melkstand und Auswirkungen von halbtägigem im Vergleich zu freiem Kontakt
Bei der muttergebundenen Kälberaufzucht, bei der Milchkühe zusätzlich zum Melken ihre eigenen Kälber für mehrere Wochen säugen, kann die Menge der ermelkbaren Milch stark reduziert sein. Ein Grund hierfür sind Alveolarmilch-Ejektionsstörungen. Daher zielt diese ...

Cartas privadas entre distancia e intimidad: el papel de la fraseología
(Peter Lang, 2018)
Private letters are dialogic interactions that are profoundly shaped by discourse traditions, communicative routines and phraseological units, especially in the salutation and conclusio. The study analyses the interplay of formulaic language and the pursuit of individuality in 16th century private letters written by Spanish emigrants from the New World to their wives in Spain.

Evaluation of Statistical-Downscaling/Bias-Correction Methods to Predict Hydrologic Responses to Climate Change in the Zarrine River Basin, Iran
(2018-04-20)
Modeling the hydrologic responses to future changes of climate is important for improving adaptive water management. In the present application to the Zarrine River Basin (ZRB), with the major reach being the main inflow source of Lake Urmia (LU), firstly future daily temperatures and precipitation are predicted using two statistical downscaling methods: the classical statistical downscaling model (SDSM), augmented by a trend-preserving bias correction, and a two-step updated quantile mapping (QM) method. The general ...

Farmers’ Perception of Water Quality and Risks in the Mashavera River Basin, Georgia: Analyzing the Vulnerability of the Social-Ecological System through Community Perceptions
(2018-08-28)
Competing natural resources usage that leads to dramatic land use changes can threaten the balance of a social-ecological system. When this is the case, communities are directly exposed to the negative consequences of those land use changes. The Mashavera River Basin is considered one of the hotspots of environmental pollution in Georgia. This is of importance for public health because the food production from this basin meets a substantial proportion of the country’s food demand. The farmers’ perception of the water ...

Evolution of Rural Livelihood Strategies in a Remote Sino-Mongolian Border Area: A Cross-Country Analysis
(2018-03-29)
Ecologically sound natural resources management is still the backbone of rural livelihoods in many regions of the world. The Altai-Dzungarian region between China and Mongolia constitutes an ideal site to study how political, economic, infrastructural, and cultural differences affect rural livelihoods. Structured semi-quantitative interviews were conducted with 483 households on both sides to characterise their current livelihood strategies and assess the importance of the various activities for the households’ current ...

Consumer Preferences for Local Food: Testing an Extended Norm Taxonomy
(2018-04-24)
Consumer attitudes toward consuming and buying locally produced food are well studied. By contrast, the topic of consumer preferences for local food, with a special emphasis on the role of norms, still lacks empirical evidence. To study the influence of norms and morals on the intention to buy local food products, a quantitative study (N = 327) focusing on external social and internalized moral norms was conducted using the constructs of the theory of planned behavior in combination with an extended norm taxonomy and ...
