Solid Fuel Production from Semi-Natural Grassland Biomass - Results from a Commercial-Scale IFBB Plant
(2018-11-01)
Biomass-based energy accounts for a notable share of renewable heat and electricity generation in Germany. Due to limited alternative uses, biomass obtained from management of semi-natural grasslands is a potential feedstock. Technical and environmental limitations exist in using this biomass for combustion, due to the presence of harmful elements. Converting biomass using integrated generation of solid fuel and biogas from biomass system (IFBB) produces a solid fuel with lower concentrations of harmful elements and ...

Development of a Sensory Method to Detect Food-Elicited Emotions Using Emotion-Color Association and Eye-Tracking
(2019-06-18)
Studying consumers’ implicit emotions has been always described as a difficult and a complicated mission due to the emotions being of a non-cognitive nature. This research aims to develop a new method based on emotion-color association (ECA) to detect consumer’s implicit food-elicited emotions using an eye-tracker tool. The study was accomplished in two experiments. The first experiment intended to build a new color scale based on the emotion-color association using the eye-tracking method and a self-reported ...

Unfolded Protein Response Suppression in Yeast by Loss of tRNA Modifications
(2018-10-23)
Modifications in the anticodon loop of transfer RNAs (tRNAs) have been shown to ensure optimal codon translation rates and prevent protein homeostasis defects that arise in response to translational pausing. Consequently, several yeast mutants lacking important anticodon loop modifications were shown to accumulate protein aggregates. Here we analyze whether this includes the activation of the unfolded protein response (UPR), which is commonly triggered by protein aggregation within the endoplasmic reticulum (ER). We ...

Bottoms up: Delivering sustainable value in the base of the pyramid
(2020-01-24)
Despite a wealth of expertise involving leading institutions over at least 15 years, a base of the pyramid (BoP) model resulting in scalability has yet to emerge. We posit that institutional gaps between BoP goals of developing human and social capital on one hand and a short‐term profit focus of business on the other contribute to the lack of scalability. We address this gap by proposing a social intermediary to link the BoP with firms involved in the BoP. The social intermediary will coordinate and interpret the ...

Net Energy Balance and Fuel Quality of an Alley Cropping System Combining Grassland and Willow: Results of the 2nd Rotation
(2021-06-22)
With the central aim to reduce greenhouse gas emissions, agroforestry systems have become popular because they can provide biomass for bioenergy conversion and thus help replace fossil energy. This article compares the net energy balances of three biomass conversion techniques for an agroforestry system consisting of willows and two types of grassland biomass as well as separate stands of grassland and willow. The period of investigation was the second willow rotation (4–6 years after establishment). The biomass ...

Analysis of Pigment-Dispersing Factor Neuropeptides and Their Receptor in a Velvet Worm
(2020-05-12)
Pigment-dispersing factor neuropeptides (PDFs) occur in a wide range of protostomes including ecdysozoans (= molting animals) and lophotrochozoans (mollusks, annelids, flatworms, and allies). Studies in insects revealed that PDFs play a role as coupling factors of circadian pacemaker cells, thereby controlling rest-activity rhythms. While the last common ancestor of protostomes most likely possessed only one pdf gene, two pdf homologs, pdf-I and pdf-II, might have been present in the last common ancestors of Ecdysozoa ...

How and why does the attitude-behavior gap differ between product categories of sustainable food? Analysis of organic food purchases based on household panel data
(2021-02-16)
Organic agriculture promotes the transformation toward sustainability because of positive effects for the environment. The organic label on food products enables consumers to make more sustainable purchasing decisions. Although the global market for organic food has grown rapidly in recent years, only a part of the organic product range benefits from this positive trend. To develop the organic market further, it is important
to understand the food-related values and attitudes that drive the purchase of organic food. ...

A value-theoretic approach to economic dynamics and evolution—synthesizing different Marxian modules in a simulation model
(2020-05-06)
The background for the present elaboration is twofold: firstly, the ongoing debate about whether the Marxian theory of value has been damaged (or even destroyed) by the alleged impossibility of solving the ‘transformation problem’ and secondly, the fact that almost all of the (later) economic manuscripts of Marx are now accessible due to the new publishing activities in the MEGA project. In regard to the former, it can be concluded that the rationale of the Marxian value concept is distorted by its Ricardian elements ...

An Overview of the Use of Genotyping Techniques for Assessing Genetic Diversity in Local Farm Animal Breeds
(2021-07-06)
The number of local farm animal breeds is declining worldwide. However, these breeds have different degrees of genetic diversity. Measuring genetic diversity is important for the development of conservation strategies and, therefore, various genomic analysis techniques are available. The aim of the present work was to shed light on the use of these techniques in diversity studies of local breeds. In summary, a total of 133 worldwide studies that examined genetic diversity in local cattle, sheep, goat, chicken and pig ...

Recent Progress in Synthesis and Application of Nanosized and Hierarchical Mordenite—A Short Review
(2021-02-26)
Zeolites with their unique properties find applications in various fields, including medicine, agronomy, ecology, production of detergents and drying agents, and in a number of industrial processes. Among zeolites, mordenite is particularly widespread because of its high silica/alumina ratio, which allows it to resist exposure to high temperatures and to acidic gases and liquids. Mordenite is commercially available as a natural mineral and as a synthesized material. This zeolite is mostly used in its synthetic form ...
