Understanding Dietary Diversity, Dietary Practices and Changes in Food Patterns in Marginalised Societies in Sri Lanka
(2020-11-13)
Micronutrient malnutrition is a serious public health problem in developing countries, including Sri Lanka. Most frequently, micronutrient malnutrition is experienced by the poorest households due to cereal-based, monotonous diets that lack dietary diversity. Sri Lankan traditional food system is changing day by day. In parallel, nutrition deficiencies, malnutrition, and noncommunicable diseases are the most significant problems today in Sri Lanka. Therefore, understanding dietary diversity and dietary changes in Sri ...

Business model innovation in strategic alliances: a multi‐layer perspective
(2020-04-17)
Business model innovation (BMI) has recently become a topic of interest for research as well as corporate practice. However, we lack specific insights into actors, drivers, and different forms of BMI as the concept is by now mainly addressed in a very general way. In this paper, we analyze how BMI takes place in strategic alliances with the focus of enhancing the recent knowledge about BMI by developing a concept that links firm‐level BMI with alliance‐driven innovation of business models. Against the background of ...

Der „Sekundenkleber“ der Stummelfüßer
(2019-12-05)
Der biologische Sekundenkleber der Stummelfüßer ist eine Quelle der Inspiration für die nachhaltige Produktion „intelligenter“ polymerbasierter Materialien. In der Natur jagen die Stummelfüßer ihre Beute mit dem proteinreichen Sekret, welches in der Lage ist, enorm belastbare Fasern zu bilden. Die Anleitung für diese Transformation ist in den Bausteinen programmiert und läuft selbstständig ohne jegliche Regulation durch den tierischen Körper ab. Elektrostatische Wechselwirkungen zwischen geladenen Proteinarealen und ...

Functional morphology of a lobopod: case study of an onychophoran leg
(2019-10-16)
Segmental, paired locomotory appendages are a characteristic feature of Panarthropoda—a diversified clade of moulting animals that includes onychophorans (velvet worms), tardigrades (water bears) and arthropods. While arthropods acquired a sclerotized exoskeleton and articulated limbs, onychophorans and tardigrades possess a soft body and unjointed limbs called lobopods, which they inherited from Cambrian lobopodians. To date, the origin and ancestral structure of the lobopods and their transformation into the jointed ...

A pilot investigation of the relationship between climate variability and milk compounds under the bootstrap technique
(2015)
This study analyzes the linear relationship between climate variables and milk components in Iran by applying bootstrapping to include and assess the uncertainty. The climate parameters, Temperature Humidity Index (THI) and Equivalent Temperature Index (ETI) are computed from the NASA-Modern Era Retrospective-Analysis for Research and Applications (NASA-MERRA) reanalysis (2002–2010). Milk data for fat, protein (measured on fresh matter bases), and milk yield are taken from 936,227 milk records for the same period, ...

Effect of Surfactants on the Flow Patterns of Horizontal Tube Bundles with a Falling Film
(2020-03-24)
The influence of two alcoholic surfactants on the flow patterns of falling film tube bundles is investigated. The flow patterns are measured in a single‐stage absorption chiller in the absence of surfactants. The surface tension of H2O/aqueous LiBr solution with different concentrations of 1‐octanol and 2‐ethylhexanol is measured at low pressure in a saturated atmosphere. Small quantities of surfactants in the aqueous solution do not have an influence on the flow patterns of the condenser and evaporator, while a shift ...

Exploration of production conditions: a step towards the development of a community-based breeding program for Butana cattle
(2020-11-17)
In Sudan, many Butana cattle farmers practice indiscriminate crossbreeding to improve the milk yield performance of cows, as organized breeding programs are lacking. Objectives of this study were to identify the current production conditions of Butana cattle and to determine farmers’ production objectives and trait preferences using a field survey. The overall aim was to explore the possibility of establishing a community-based breeding program for the genetic improvement of the breed. A semi-structured questionnaire ...

Fusion of Ultrasonic and Spectral Sensor Data for Improving the Estimation of Biomass in Grasslands with Heterogeneous Sward Structure
(2017-01-21)
An accurate estimation of biomass is needed to understand the spatio-temporal changes of forage resources in pasture ecosystems and to support grazing management decisions. A timely evaluation of biomass is challenging, as it requires efficient means such as technical sensing methods to assess numerous data and create continuous maps. In order to calibrate ultrasonic and spectral sensors, a field experiment with heterogeneous pastures continuously stocked by cows at three grazing intensities was conducted. Sensor ...

Social Loafing in the Refugee Crisis: Information about Existing Initiatives Decreases Willingness to Help
(2017-05-11)
In light of the European refugee situation, we investigate how information about others’ support influences individuals’ willingness to help. When individuals see information about other people supporting refugees, they may either be influenced by a descriptive norm, and act accordingly. Alternatively, they may perceive that others are already doing the job, and thus engage in social loafing. In an experiment (N = 132), we tested these competing predictions. Specifically, participants were exposed to a map of Germany ...
