Anthropometric indices, lipid profile, and lipopolysaccharide-binding protein levels in metabolic endotoxemia: A case-control study in Calabar Metrop…

2020

Objectives: To determine the anthropometric indices, lipopolysaccharide-binding proteins (LBP), and lipid profile in patients with metabolic endotoxemia. Methods: The study comprised of 47 patients with metabolic endotoxemia (the metabolic endotoxemia group) and 43 controls (the control group). Patients in the metabolic endotoxemia group were categorized further into three subgroups including the normal weight group (n=8), the overweight group (n=12) and the obese group (n=27). Height, weight, waist, and hip circumference were measured, and waist-hip ratio (WHR) and body mass index (BMI) were calculated. LBP was determined by ELISA and total cholesterol, triglycerides, high density lipoprot…

Existence of optimal transport maps in very strict CD(K,∞) -spaces

2018

We introduce a more restrictive version of the strict CD(K,∞) -condition, the so-called very strict CD(K,∞) -condition, and show the existence of optimal maps in very strict CD(K,∞) -spaces despite the possible lack of uniqueness of optimal plans. peerReviewed

The importance of social networks in the Norwegian firewood industry

2013

Accepted version of an article from journal of Biomass and Bioenergy This study examines the relationship between social network size, innovation and firm performance among firewood producers in Norway. Moreover, it investigates how this relationship is affected both by the structure and variations in networks and by firm size and age. A questionnaire-based survey was sent to managers of firms (including one-person firms) in the firewood industry in Norway. A total of 645 usable replies were received, and the theoretical model was tested using structural equation modeling. The findings show that social network size has a positive effect on firm performance via innovation by firewood produce…

Microwave-assisted conversion of novel biomass materials into levulinic acid

2018

Levulinic acid is considered one of the most important platform chemicals. It is currently produced mainly from lignocellulosic biomasses. However, there are also other abundant biomass materials, which could be used as raw materials for levulinic acid production. In this work, levulinic acid was produced from two novel biomasses in the presence of Brønsted (H2SO4) and Lewis acid (CrCl3·6H2O or AlCl3·6H2O) catalysts. The studied materials were carbohydrate-rich potato peel waste and sporocarps of the fungus Cortinarius armillatus. Reaction conditions, i.e., time, temperature, H2SO4, and Lewis acid concentrations, were studied by utilizing full 24-factorial experimental designs. Microwave ir…

Applying Minimalism in the Real World: Results From a Workshop

2020

Minimalism is a user-centered, contextual and goal-oriented approach to technical communication originally developed by John M. Carroll (1990). In minimalism, the aim is to produce user documentation that focuses on the user’s needs, helps the user recover from error situations, and strengthens the user’s skills in working with the system (Carroll & van der Meij 1995: 245). The challenge with minimalism has been its practical application: although user-centeredness – the core of minimalism – is the key issue in technical communication, the abstract nature of the approach and its focus on software documentation has made it difficult to apply in industry settings (Virtaluoto, Suojanen & Isohe…

Avaliando o caso da dengue na Argentina em 2009: discriminação e medo

2010

Após quase uma década, a reaparição da Dengue na Argentina causou pânico e medo. Diferente da Bolívia, do Brasil e do Paraguai, onde as políticas de prevenção têm sido seguidas, o futuro da dengue fica incerto para a Argentina; este trabalho não tem qualquer afiliação política, mas destaca o papel da mídia de massa na cobertura das epidemias. A questão de se um jornal ou corporação de mídia de massa deveria manter um mínimo de objetividade é extensa demais para ser resolvida neste artigo curto. Entretanto, temos apresentado um modelo que ajudará outros pesquisadores a interpretarem temas desta natureza no futuro. Nos momentos de desordem, incerteza ou desastre, as sociedades passam por uma …

CHARACTERIZATION AND ENERGETIC METABOLISM ANALYSIS OF DIFFERENT POPULATIONS OF UMBILICAL CORD MESENCHYMAL STEM CELLS FOR THE TREATMENT OF STROKE

Stroke is a leading cause of death and disability worldwide. A direct consequence of oxygen and glucose deprivation during stroke is the dysfunction of mitochondria that impairs oxidative metabolism and contributes to oxidative stress, neuronal death and inflammation. Human umbilical cord (UC)-derived MSCs (UC-MSCs) are an attractive source for regenerative medicine purposes due to their self-renewal and multipotent differentiation potential, immunomodulatory and anti-inflammatory abilities. Notably, because UC is supplied from only three blood vessels, the UC-MSCs are physiologically adapted to survive in a relatively hypoxic and glucose poor environment leading to the hypothesis that thes…

Application of computational fluid dynamics technique in electrodialysis/reverse electrodialysis processes

2022

This Chapter treats the application of CFD technique in ED/RED processes. CFD simulations are able to predict flow and mass transfer in channels filled with spacers or membrane profiles, by providing dimensionless correlations useful for process models. At a larger scale, manifolds of the stack and inlet/ outlet zones of the channel can be simulated. Numerical models can include the computation of the electrical potential, thus characterizing the process performance. Direct numerical simulations can elucidate the complex phenomenology of overlimiting transport and of chaotic electrokinetic flows.

Reuse of Food Waste: The Chemical Composition and Health Properties of Pomelo (Citrus maxima) Cultivar Essential Oils

2022

The aim of the present study is to investigate the chemical profile, antioxidant activity, carbohydrate-hydrolysing enzyme inhibition, and hypolipidemic effect of essential oils (EOs) extracted from Sicilian Citrus maxima (pomelo) flavedo. Using gas-chromatography-mass spectrometry analysis (GC-MS) we analysed the Eos of five cultivars of C. maxima, namely, ‘Chadock’, ‘Maxima’, ‘Pyriformis’, ‘Terracciani’, and ‘Todarii’, and their blends. The antioxidant activity was performed by using a multi-target approach using 2,2′-Azino-Bis-3-Ethylbenzothiazoline-6-Sulfonic acid (ABTS), 2,2-Diphenyl-1-picrylhydrazyl (DPPH), ferric reduc…
