Model Predictive Control of Grid Forming Converters with Enhanced Power Quality

This paper proposes an enhanced finite control set model predictive control (FCS-MPC) strategy for voltage source converter (VSC) with a LC output filter. The proposed control scheme is based on tracking the voltage reference trajectory by using only a single-step prediction within the controller horizon. Besides, the suitability of different frequency control schemes with the proposed scheme to prevent from inherent variable switching behaviour of conventional FCS-MPC is investigated. Based on that, the proposed method targets two major factors influencing power quality in grid forming applications by enhancing the output voltage harmonic distortion and also preventing variable switching behaviour of FCS-MPC. Although compared to multi-step prediction approaches, only a single-step multi-objective cost function to improve computation efficiency is utilized, the introduced control schemes are able to deliver higher power quality compared to its counterpart methods as well. Furthermore, the effect of different applied cost functions on the transient response of the system is studied and investigated for the future use of the VSC in microgrids (MGs). The effectiveness of the proposed scheme was assessed by simulation using MATLAB/SIMULINK and experiment using a 5.5 kVA VSC module and the results were in good agreement.

Amount and amino acid composition of basal endogenous protein losses at the terminal ileum of broilers

In this report literature data on endogenous ileal protein and amino acid losses in broilers are reviewed. The aim was to propose an estimated value for the flow of basal endogenous protein at the terminal ileum and to determine the amino acid composition of the basal endogenous protein. The proposed basal endogenous ileal amino acid flows can subsequently be used to calculate standardized ileal digestible amino acid values for feedstuffs for poultry from experimentally determined apparent ileal digestible amino acids. Basal endogenous ileal amino acids losses are expressed in mg per kg dry matter intake. The quantitative flow of basal endogenous amino acids at the terminal ileum is dependent on the methodology used for quantification, the age of the animals and the presence of phytate and phytase in the diet. From our literature survey we concluded that the nitrogen free feeding method (NFD) and the regression method (REG) are most suitable to determine basal endogenous amino acids at the terminal ileum in broilers. Based on 29 observations from 25 studies with NFD, 6 observations of 4 REG studies, 5 observations of 3 HDP studies and 2 observations from 2 EHC studies, we calculated the basal ileal endogenous amino acid flow in broilers aged 15 to 45 days. The total flow of basal endogenous ileal amino acids amounts 5.90 g AA per kg dry matter intake. The values for basal endogenous ileal flow of the individual amino acids are used by CVB to estimate standardized ileal amino acid digestibility values from apparent amino acid digestibility values of feedstuffs for broilers (see CVB Documentation Report no. 61). Ileal endogenous protein is rich in GLU, ASP, GLY, THR, SER and PRO and rather closely reflects the composition of mucoproteins.
Uncovering bioactive compounds and potential mechanisms of Jieduan-Niwan Formula against liver failure

Background Liver failure is considered as the inability of the liver to perform its normal synthetic and metabolic function. Our previous data showed that Jieduan-Niwan formula (JDNW) induced liver failure, while its underlying mechanism remains unknown. Methods In the present study, we performed a network pharmacology to analyze the bioactive ingredients and related targets. Compound and target data of JDNW formula were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database (TCMSP), and targets related to liver diseases were obtained from DisGeNET database. Information of protein protein interaction were retrieved from STRING database. Network construction and degree calculation were used Cytoscape software. Metascape web-server was used for GO and KEGG pathway enrichment. A microarray data series (GSE72081) was obtained from Gene Expression Omnibus database and analyzed using R project and Connectivity Map. Ledock was used for molecular docking. Results A total of 114 unduplicated active ingredients were identified after ADME screening. After construction of a target-liver disease network, 28 targets were identified for anti-liver failure effect. These targets were significantly enriched in fluid shear stress and atherosclerosis, pathways in cancer, IL-17 signaling pathway, HIF-1 signaling pathway, insulin resistance, toxoplasmosis, prostate cancer, microRNAs in cancer, NF-kappa B signaling pathway, Chemical carcinogenesis, VEGF signaling pathway and complement and coagulation cascades pathways. After analyzing a public microarray data of quercetin, we found biological action of some NFκB inhibitors was similar to quercetin. Molecular docking study showed that quercetin possessed a capability to bind on IKKβ and inhibited NFκB activation. Conclusions JDNW formula treated liver failure via multiple targets and multiple pathways, including NFκB signal. Quercetin was identified as a key bioactive ingredient of JDNW formula and its anti-liver failure effect may involve in NFκB inhibition.
REACTIVE GAMES AS AN EXAMPLE OF EXTENSIVE USE OF EVOCATIVE NARRATIVE ELEMENTS IN DIGITAL GAMES: THE CASES OF DWARF FORTRESS AND RIMWORLD

There are many types of digital games – some focus more on new gameplay mechanics while others focus more on new ways to tell and deliver their stories. Some games, in their goal of creating more engaging narratives, push the environmental storytelling and evocative narrative elements to their limits, allowing for a unique emergent narrative experience for players. Consequently, players now recognize a specific type of game, call - ing them, “reactive games”, in which the events and story of the gameworld occur without the need for the input of the player, who instead must react to the events and problems the game sends their way. This article presents two examples of reactive games which create a unique gameplay experience by exploiting the limits of environmental storytelling, evocative narrative elements, and emergent narrative: Dwarf Fortress and RimWorld .

Trophic status and diversity of fish species in selected tributaries of Bentota River

Present study was carried out to investigate the, abundance and trophic status of fishes inhabiting tributaries of the Bentota River. Fish were sampled using gill nets, seine nets, cast nets and some were also collected from fishermen’s catches harvested at the tributaries of the Benthota River in Katapola, Ganegoda, Avitthawa, Yagirala and Galatara. To investigate the trophic status, stomach contents were analyzed and quantified using the Point method based on the percentage of bio volume per food category. Ten species of fish were recorded from all five sites, including two endemic species, Clarias brachysoma, Channa orientalis and one invasive alien fish Chitala ornata. Some indigenous species such as Puntius vittatus (n=400), Rasbora daniconius (n=134), Puntius dorsalis (n = 42) and Trichogaster pectoralis (n=71) were also caught in reasonable number. Parts of fish (scales, fins and flesh), mollusks, adult insects, insects larvae, macrophytes and digested/detritus matters were identified as main food categories in the stomach. Based on the gut content analysis, three feeding guilds i.e. piscivorous, herbivorous and zooplanktivorous, were identified. High diet overlap values were recorded in species pairs belonged to the same feeding guild i.e. Chitala.ornata- Channa orientalis while low diet overlap values were recorded in species belonged to different feeding guilds. Remains of fins of Channa orientalis, and Rasbora daniconius and some invertebrates observed in stomach contents of C. ornata, indicated its negative impacts on biodiversity in study sites. Therefore urgent attention should be paid to population control of C.ornata and to prevent its further invasion into new habitats.
Carbon Xerogel nanocomposite materials for electrochemical devices: application to heavy metal detection

En aquesta Tesi es descriu la fabricacio d'electrodes nanocomposits de carboni poros en forma de capa prima i capa gruixuda i la seva aplicacio en l'analisi de metalls pesants en aigues. Aquests nanocomposits de carboni es van preparar a partir de la pirolisi de materials obtinguts per quimica sol-gel, concretament de gels de resorcinol-formaldehid i de resorcinol-formaldehid amb silice, que contenien precursors de bismut. Els gels pirolitzats presenten una estructura de carbo poros amb porositat oberta que conte nanoparticules de bismut ben distribuides. Aquests materials es van moldre fins a obtenir una pols de granulometria adequada per fer electrodes de pasta de carboni per ser estudiats al laboratori i electrodes serigrafiats de capa gruixuda de tipus comercial. Aquests electrodes presenten una resposta molt bona en l'analisi de metalls pesats en aigues. Els limits de deteccio de Pb(II), Cd(II) i Ni(II) obtinguts amb aquest electrodes estan molt per sota de la concentracions maximes d'aquests metalls contemplades en les normatives d'aigua per al consum de la Unio Europea i els Estats Units (US-EPA). Es va dur a terme l'analisi de Pb(II), Cd(II), Ni(II), Zn(II) i Cu(II) en aigues reals de diferent origen i complexitat i es va veure que en la majoria de casos s'obtenien resultats que estaven d'acord amb les mesures fetes per espectroscopia de masses. Tambe es van estudiar les limitacions dels sensors desenvolupats i interferencies entre els diferents analits. Pel que fa als electrodes en capa prima, per spin-coating es van dipositar capes primes uniformes i continues de sols de resorcinol-formaldehid que contenien un precursor de SiO2 sobre oblies de SiO2/Si de 4 polzades. Es va comprovar que despres de la pirolisi l'adhesio de les capes de carboni sobre la capa de SiO2/Si millorava molt incorporant en el sol el precursor de SiO2. Els electrodes de carboni/silice en capa prima es van fabricar utilitzant processos de fotolitografia i soft-lithography. Aquests electrodes no donaven cap resposta en voltamperometria ciclica en solucions de ferri/ferrocianur pero en canvi si que ho feien amb una sonda redox de ferroce. En el cas de les capes primes, la incorporacio de nanoparticules de bismut seguint un procediment analeg al de la sintesi dels gels macroscopics resultava problematica degut a que durant la pirolisi s'evaporava tot el bismut. Tanmateix, aquests electrodes es van poder utilitzar amb exit per a l'analisi de metalls pesants fent simultaniament la co-deposicio electroquimica de bismut amb els metalls pesats analitzats.
Parental Socioeconomic Status as a determinant of breastfeeding    : an analysis of the Korea National Health and Nutrition Examination Survey ( 2013 ~ 2017 )

Background: The importance of breastfeeding is well known. One of important factors affecting breastfeeding is socioeconomic status. We investigated the relationship between socioeconomic status and breastfeeding to promote future breastfeeding projects. Methods: Data were collected from the 2013 - 2017 Korea National Health and Nutrition Examination Survey (KNHANES). We evaluated the demographic information and parents’ socioeconomic status of 1,220 children under 60months.Results: A total 1,220 children were included in this study. Some of the socioeconomic factors were associated with breastfeeding. Mothers’ education level (≥13years: odd ratio[OR], 2.79; 95% confidence interval [CI], 1.21-6.42), middle high of mother’s income level (OR, 2.30; 95% CI, 1.18-2.84), no smoking status (OR, 3.07; 95% CI, 1.28-7.36), body mass index(BMI) (< 25(kg/m 2 ): OR, 1.82; 95% CI, 1.12-2.95) were associated with breastfeeding (p<0.05). Also, fathers’ age (30s: OR, 4.88; 95% CI, 1.82-13.04), education level(≥13years: OR, 7.94; 95% CI, 3.12-20.18) were associated with breastfeeding (p<0.05). After controlling for the confounding factors, mothers’ BMI, fathers’ age and educational level were statistically significant.Conclusion: This study demonstrated that socioeconomic factors were associated with breastfeeding in Korea.

The high photocatalytic activity and reduced band gap energy of La and Mn co-doped BiFeO3/graphene nanoplatelet (GNP) nanohybrids

Recently, bismuth ferrites have attracted great interest in the field of photocatalysis due to their magnetic nature and narrow band gap. Herein, nanohybrids of lanthanum (La) and manganese (Mn) co-doped BiFeO3 (BLFMO)/graphene nanoplatelets (GNPs) have been synthesized. The hybrids were prepared by two different but simple and low-cost synthesis routes: (i) co-precipitation (namely the C-series), and (ii) hydrothermal (namely the H-series) methods. This article details a comparison of the C-series and H-series BLFMO/GNP nanohybrids based on their photocatalytic activity and band gap. The H-series nanohybrids showed a more crystalline structure, reduced band gap and less dye removal compared to the C-series nanohybrids. The enhanced dye removal (92%) of the C-series nanohybrids is attributed to their high surface area (55 m2 g−1) due to GNP incorporation inside the BLFMO/GNP nanohybrids. The higher surface area enables more adsorption of dye molecules over the catalyst surface under dark conditions. In addition, the band gap of the BLFMO/GNP nanohybrids was reduced from 2.04 eV (pure BiFeO3) to 1.40 eV (BLFMO/GNPs) because of the presence of new donor energy levels with Mn loading. The calculated particle sizes from Scherrer’s formula were 19.3–23.5 nm (C-series) and 22.5–26 nm (H-series). The estimated particle size calculated via transmission electron microscopy (TEM) is approximately 31 nm for the C-series nanohybrids. The graphene based nanohybrids significantly enhanced dye removal compared to pure BiFeO3 (44%) under visible light irradiation. The low cost, easy preparation and higher catalytic activity of the BLFMO/GNP nanohybrids reported here make nanohybrids suitable candidates for practical applications.
TECHNICAL PAPERS ELECTROCHEMICAL SCIENCE AND TECHNOLOGY Performance Modeling of the Ballard Mark IV Solid Polymer Electrolyte Fuel Cell I. Mechanistic Model Development

A parametric model predicting the performance of a solid polymer electrolyte, proton exchange membrane (PEM) fuel cell has been developed using a combination of mechanistic and empirical modeling techniques. This paper details the mechanistic model development. Mass transport properties are considered in the mechanistic development via StefanMaxwell equations. Thermodynamic equilibrium potentials are defined using the Nernst equation. Activation overvoltages are defined via a Tafel equation, and internal resistances are defined via the Nernst-Planck equation, leading to a definition of ohmic overvoltage via an Ohm's law equation. The mechanistic model cannot adequately model fuel cell performance, since several simplifying approximations have been used in order to facilitate model development. Additionally, certain properties likely to be observed in operational fuel cells, such as thermal gradients, have not been considered. Nonetheless, the insights gained from the mechanistic assessment of fuel cell processes were found to give the resulting empirical model a firmer theoretical basis than many of the models presently available in the literature. Correlation of the empirical model to actual experimental data was very good.
Mechanism of Overcoming Oxaliplatin Resistance Using HT29 Subcloning

Background: Cancer cells are different from normal healthy cells even though they reside within the same tissue and adapt to others. This intra-tumoral heterogeneity is the reason for chemo-resistance, and the emergence of one or more clones, which are resistant to chemotherapeutic drugs, causing clonal outgrowth to form recurrent cancer mass. The need for personalized chemotherapy is increasing because of the tumor heterogeneity and diverse mechanism of chemotherapy resistance. The recent accumulation of extensive evidence for the existence of cancer stem cells strengthens the cancer stem cell hypothesis for chemotherapy resistance and relapse. The development of a primary culture of cancer cells is essential for functional analysis like the sensitivity of chemotherapeutic drugs and the evaluation of the characteristics of cancer stem cells. Methods: We used a clonal cylinder to establish sub-clones originated from a single cell. Twenty-two sub-clones were successfully established, and eleven clones were selected according to their growth rate and analyzed. The sub-clones with low expression of BRAF, MEK2, and ERK, but not EGFR or KRAS, showed a correlation with the doubling time. We grouped the sub-clones as the fast-growing group and the slow-growing group of the HT29 cell line. Three out of five slow-growing sub-clones showed resistance to oxaliplatin treatment. All oxaliplatin-resistant sub-clones overexpressed ABCC2, and no relevance was found with ABCB1 and ABCG2. Active efflux of the drug by ABCC2, but not by ABCB1 or ABCG2, was confirmed with the inhibitor study using each specific inhibitor. The viability of resistant sub-clones decreased after the MK571 treatment, but other clones were not responsive. CD44 expression in oxaliplatin-resistant sub-clones was higher than that of sensitive clones. Conclusions: This study provides definite evidence of heterogeneity using a cancer cell line. Based on our studies, it appears that intra-tumoral heterogeneity of human cancer tissue is responsible for the development of chemotherapy resistance in cancer. These sub-clones are an excellent model for testing efficacy of anti-cancer drug candidates for advanced cancer therapy. The experimental design and concept of this study could be applied to personalized chemotherapy.
Aerosol-to-liquid collection: A method for making aqueous suspension of hydrophobic nanomaterial without adding dispersant

ABSTRACT This article introduces an aerosol-based technique to make aqueous suspension of hydrophobic nanomaterial without adding dispersant. The method is intended for making a test-sample for evaluating the toxicities of nanomaterial by intra-tracheal administration. The method can wet the surface of hydrophobic nanomaterial within a few seconds. After the wetting process five to ten minutes of sonication assisted with manual stirring can fully disperse the hydrophobic nanomaterials in water. Two types of TiO2 nanomaterial were used in this study; Tayca JMT-150IB whose surfaces are coated with negatively charged hydrophobic functional group, and P25 whose surfaces are naturally hydrophilic. Nanomaterials are aerosolized by a dry-method and become micrometer-sized agglomerates. Then supersaturated water vapor is condensed onto these airborne agglomerates by using a growth tube collector. The collected suspension (CS) of hydrophobic nanomaterial (JMT-150IB) is prepared in two steps; airborne agglomerates are collected onto a flat surface then transferred to liquid-water and subsequently sonicated for complete dispersion. This method works equally well for making the CS of hydrophilic nanomaterial. Size distribution measurements of the CS show that airborne agglomerates of TiO2 dissociate into smaller units of agglomerates once they are captured into water, and the sizes of the agglomerates are in the nanometer to sub-micrometer range. Light scattering technique is used to show that a short sonication process can reproduce the particle number concentration of the CS after long storage.
