Organic acids and alcohols quantification by HPLC/RID in sugarcane vinasse: analytical method validation and matrix effect assessment

Alan Nascimento Bernardes, Leandro Augusto Gouvêa De Godoi, Priscila Rosseto Camiloti, Absai Da Conceição Gomes, Bruna Larissa Sandy Sanchez, Ana Paula Rodrigues Torres & Lívia Silva Botta
The composition of sugarcane vinasse varies according to the substrate of alcoholic fermentation, e.g. if it is sugarcane juice and/or molasses. Regardless of the origin, the main organic compounds found in sugarcane vinasse are organic acids, alcohols and a low amount of carbohydrates. To access the organic composition of such wastewater, the present paper describes a high-performance liquid chromatography (HPLC) separation method coupled to a Refractive Index Detector (RID) in order to quantify the organic...

PREDAC 2019 Poster: Storyboarding in class, ENGLISH

Bianke Loedolff, Nelisiwe Chonco, Malizukiswe V. Vacu, Craig Ehrenreich, Grace Aguti & Xiangcong A. Luo
Storyboarding is a visual storytelling, cooperative learning tool that could benefit learners from all disciplines in educational structures. This visual display enables learners to see interrelationships among the core concepts outlined in a module framework. Both teacher and learners participate in this storyboarding process through continuous discussion in the classroom. Concepts and ideas are displayed in clear visual form on a storyboard and could typically include (i) a topic revision and introduction to advanced concepts...

Exposure to heavy metals from point pollution sources and risk of incident type 2 diabetes among women: a prospective cohort analysis

Michael Hendryx, Juhua Luo, Catherine Chojenta & Julie E. Byles
Heavy metal exposures may contribute to diabetes risk but prospective studies are uncommon. We analyzed the Australian Longitudinal Study on Women’s Health (three cohorts aged 18–23, 45–50, or 70–75 at baseline in 1996, N = 34,191) merged with emissions data for 10 heavy metals (As, Be, Co, Cr, Cu, Hg, Mn, Ni, Pb, Zn) from the National Pollutant Inventory. Over 20-year follow-up, 2,584 women (7.6%) reported incident diabetes. Cox proportional hazards regression models showed that...

A regionalization method for clustering and partitioning based on trajectories from NLP perspective

Yizhuo Li, Teng Fei & Fan Zhang
Regionalization attempts to group units into a few subsets to partition the entire area. The results represent the underlying spatial structure and facilitate decision-making. Massive amounts of trajectories produced in the urban space provide a new opportunity for regionalization from human mobility. This paper proposes and applies a novel regionalization method to cluster similar areal units and visualize the spatial structure by considering all trajectories in an area into a word embedding model. In this...

Supplementary Material for: Distinct Association of Serum Vitamin D Concentration with Disease Activity and Trough Levels of Infliximab and Adalimumab during Inflammatory Bowel Disease Treatment

N.-C. Mechie, E. Mavropoulou, V. Ellenrieder, S. Kunsch, S. Cameron & A. Amanzada
Background: Studies of serum vitamin D (Vit-D) levels in patients with inflammatory bowel disease (IBD) treated with anti-tumor necrosis factor-alpha (anti-TNF-α) agents are scarce. The conjunction of Vit-D as well as zinc levels and anti-TNF-α-trough concentrations (TC) has not yet been explored. Objectives: To determine the association of serum Vit-D, zinc and C-reactive protein (CRP) levels with clinical and biochemical remission and a possible correlation with serum TC and antibody levels of anti-TNF-α. Methods: Serum...

Molecular and morphological characterization of the Achnanthidium minutissimum complex (Bacillariophyta) in Petuniabukta (Spitsbergen, High Arctic) including the description of A. digitatum sp. nov.

Eveline Pinseel, Pieter Vanormelingen, Paul B. Hamilton, Wim Vyverman, Bart Van De Vijver & Kateřina Kopalova
Recent morphology-based investigations of freshwater Arctic diatoms suggest that many species remain to be discovered, reflecting a unique polar flora. During a survey of the freshwater diatom flora of northern Billefjorden, including the Petuniabukta fjord region (Spitsbergen), several morphodemes belonging to the Achnanthidium minutissimum species complex were recorded. Molecular phylogenies based on rbcL, 28S and 18S sequences, including single cells from Canada and strains from Marion Island (sub-Antarctica) and GenBank revealed the presence of 12...

Replacement optimization of ageing infrastructure under differential inflation

M. Van Den Boomen, G. Leontaris & A. R. M. Wolfert
Ageing public infrastructure assets necessitate economic replacement analysis. A common replacement problem concerns an existing asset challenged by a replacement option. Classic techniques obtained from the domain of engineering economics are the mainstream approach to replacement optimization in practice. However, the validity of these classic techniques is built on the assumption that life cycle cash flows of a replacement option are repetitive. Differential inflation undermines this assumption and therefore more advanced replacement optimization techniques are...

Supplementary material from "Biased movement drives local cryptic coloration on distinct urban pavements"

Pim Edelaar, Adrian Baños-Villalba, David P. Quevedo, Graciela Escudero, Daniel I. Bolnick & Aída Jordán-Andrade
Explanations of how organisms might adapt to urban environments have mostly focused on divergent natural selection and adaptive plasticity. However, differential habitat choice has been suggested as an alternative. Here, we test for habitat choice in enhancing crypsis in ground-perching grasshoppers colonizing an urbanized environment, composed of a mosaic of four distinctly coloured substrates (asphalt roads and adjacent pavements). Additionally, we determine its relative importance compared to present-day natural selection and phenotypic plasticity. We found...
