Comparison of linear discriminant analysis, support vector machine and artificial neural network in classifying Nigerian local turkeys based on plumage colours using biometric traits
(2022-10-18)
The ability of linear discriminant analysis (LDA), support vector machine (SVM), and artificial neural network (ANN) models to differentiate biometric traits of Nigerian local turkeys was investigated in this study. The biometric traits (bodyweight, body length, breast girth, thigh length, shank length, keel length, wing length, and wingspan) in 200 (20-week-old) turkeys were measured. Seventy percent of the datasets were used to train the three models, with the remaining 30% being used to test their performance. All ...

Marktstudie zu regionalen Bio-Lebensmitteln in Hessen
(2022)
Die vorliegende Studie gibt einen ersten Einblick in die aktuelle Situation der landwirtschaftlichen Öko-Erzeugung, der Verarbeitung und des Handels ökologischer Lebensmittel in Hessen. Am Beispiel von ausgewählten Wertschöpfungsketten (WSK) wird untersucht, welche Schwächen und Stärken und welche Herausforderungen für regionale Produktion, Verarbeitung und Handel von ökologischen Lebensmitteln bestehen. Ziel der Studie ist es, die aktuelle Situation darzustellen, Schwachstellen zu identifizieren und Ansatzpunkte zu ...

Circular bioeconomy: Actors and dynamics of knowledge co-production in Finland
(2022-09-01)
The circular bioeconomy is a highly scrutinized concept in Finland and internationally, with a high degree of polarization regarding forest utilization rates and distrust between certain actors. This offers an interesting case for an exploratory analysis of issues associated with knowledge co-production. Knowledge co-production entails the integration of different knowledge types and collaboration across multiple societal actors with potentially conflicting viewpoints and agendas. We interviewed key organizations ...

Responses of Arnica montana L. and montane Nardus grasslands to climate change in Central German Uplands
(2022-02)
Species-rich montane Nardus grasslands and their characteristic and highly valued plant species arnica (Arnica montana L.) are two elements of low-intensively-used, species-rich mountain grassland in Central German Uplands. In times of present and future global change, new stressors, like those related to climate change, will come into action, and are predicted to lead to a further decline of Arnica montana and Nardus grasslands. This is of specific concern in lower mountain ranges, where species and habitats are ...

The Importance of tRNA Modification and SSD1 Status for Protein Homeostasis and Cell Viability
(2022-03)
Chemical modifications of anticodon loop are required to support tRNA function in mRNA decoding and to prevent protein aggregation in the eukaryotic model system Saccharomyces cerevisiae. This work investigates the effects of mutation in the gene encoding the Deg1 pseudouridine synthase. It is known that the mutation of the human DEG1 orthologue PUS3 causes severe neurological and developmental defects, emphasizing the general importance of the modification. However, the exact cellular consequences of deg1/pus3mutation ...

Towards crop communities: exploring wheat diversity, wheat-pea species mixtures and farming practice in a food system context
(2022-06)
This thesis combines experimental work on heterogeneous crop populations (HP) and species mixtures (SM) with a social scientific and participatory approach. Chapter 1 introduces crop communities as a concept to integrate multiple approaches to diversify farming systems. HPs provide intraspecific and SM interspecific diversity in crop communities. A key challenge for the genetic improvement of HPs, especially for root traits is to combine effective selection to improve HPs while maintaining intraspecific diversity. ...

Functional characterization of disease-associated mutations in type I cGMP-dependent protein kinase
(2022-08)
Cardiovascular diseases are the leading cause of death worldwide, and while mainly associated with behavioral risk factors, they can also be linked to genetic disorders. The cGMP-dependent protein kinase type I (PKG I) plays a pivotal role in the homeostasis of the vasculature by mediating NO/cGMP-dependent relaxation of vascular smooth muscle cells. A recently described genetic risk factor associated with PKG I results in heritable thoracic aortic aneurysms and dissections (TAAD). Although PKG isoforms Iα and Iβ ...

A scoping review on the presence of antibiotic residues in milk and the government strategies to control the use of antibiotics in milk industry in India
(2022-10-15)
In dairy farms, antibiotics are administered for therapeutic and prophylactic purposes. Lack of adherence to withdrawal periods and irrational use of antibiotics in the feed may lead to antibiotic residues (AR) in milk. Evidence suggests that the risk of AR in the milk is believed to be higher in developing countries due to multifarious reasons. The issue of residues in milk is predominantly concerning in India, as it has the largest consumer base in the world. Many studies have identified that consuming milk ...
