Analysis of Animal Bedding Heterogeneity for Potential Use in Biorefineries Based on Farmyard Manure

Animal bedding, a mixture of straw and manure, could be used as a feedstock for bioenergy production, but its heterogeneity poses new challenges in its use in biorefineries. We have investigated the origin of this heterogeneity and quantified it, and discuss its impact on bioenergy production. Samples were collected from the bedding at different points and depths and analysed by first separating t

Arterial Input Functions and Tissue Response Curves in Dynamic Glucose-Enhanced (DGE) Imaging: Comparison Between glucoCEST and Blood Glucose Sampling in Humans

Dynamic glucose-enhanced (DGE) imaging uses chemical exchange saturation transfer magnetic resonance imaging to retrieve information about the microcirculation using infusion of a natural sugar (D-glucose). However, this new approach is not yet well understood with respect to the dynamic tissue response. DGE time curves for arteries, normal brain tissue, and cerebrospinal fluid (CSF) were analyzed

Development of specific monoclonal antibodies against different forms of alpha-synuclein as diagnostic tools for synucleinopathies

Synucleinopathies, including Parkinson’s disease (PD), dementia with Lewy bodies(DLB) and multiple system atrophy (MSA), are a group of neurodegenerative disorders characterized by the abnormal accumulation of insoluble alpha-synuclein (α-syn) aggregates in the brain. The detection of α syn pathology has relied vastly on the use of several antibodies, which were mostly generated against different

Are Model Cities an Effective Instrument for Urban Environmental Governance?

Since the 1980s, China’s central government has created various model and incentive schemes aimed at systematically and concurrently promoting innovative approaches for protecting the urban ecological environment. In this context, programmes such as the ‘model city for protecting the environment’, ‘garden city’, ‘eco-city’, or ‘low-carbon city’ have become an integral part of China’s system for ur

Assessing tissue heterogeneity by non-Gaussian measures in a permeable environment

In diffusion MRI, the deviation of the Ensemble Average Propagator (EAP) from Gaussianity conveys information about the microstructural heterogeneity within an imaging voxel. Different measures have been proposed for assessing this heterogeneity. This paper assesses the performance of the Diffusional Kurtosis Imaging (DKI) and Simple Harmonics Oscillator Reconstruction and Estimation (SHORE) appro

Estimating faults modes in ball bearing machinery using a sparse reconstruction framework

In this work, we present a computationally efficient algorithm for estimating fault modes in ball bearing systems. The presented method generalizes and improves upon earlier developed sparse reconstruction techniques, allowing for detecting multiple fault modes. The measured signal is corrupted with additive and multiplicative noise, yielding a signal that is highly erratic. Fortunately, the damag

Molecular systematics of the arctiine tribe Syntomini (Lepidoptera, Erebidae)

The Old World tribe Syntomini is the most neglected of the three major groups of the subfamily Arctiinae – the most megadiverse lineage (c. 11 000 species) of the superfamily Noctuoidea, comprising about a quarter of its entire species diversity. In none of the previous morphogenetic studies was Syntomini (which are often conspicuously spotted, aposematic moths) sampled adequately enough to provid

Cisterna Magna Injection in Rats to Study Glymphatic Function

The recently discovered glymphatic system, which supports brain-wide clearance of metabolic waste, has become the subject of intense research within the past few years. Its nomenclature arose due to its functionally analogous nature to the lymphatic system in combination with glial cells that are part of its anatomical boundaries. The influx of cerebrospinal fluid (CSF) from perivascular spaces in
