Published: June 2019

Flood events are dependent on meteorological conditions but also depend on several other factors that are case specific, with relevance for reservoir operation. Hydrological and hydrodynamic models are valuable tools for understanding complex river hydrodynamics during flood events. These tools have been applied to improve understanding of the causes for an urban flood event that occurred between 9 and 11 January 2016 in the Mondego river basin, at Coimbra city (Portugal). Seven different factors that can, independently, influence the river flow at the study site were identified: three of them can be associated with the operational discharge schemes of the three upstream dams; two factors with the runoff flows from uncontrolled contributing sub-basins; another one related to discharge measurement uncertainty at a downstream dam; and finally, the seventh studied factor was sedimentation occurring in the main channel of the flooded river stretch. Hydroinformatic tools were applied in different scenarios allowing the characterization and identification of each one of the identified key factors responsible for the flood event. A proposal for a flood early warning system is presented based on the knowledge resulting from the studied flood event.

Published: June 2019

We studied water loss performance in a model plant, the Tufted sedge (Carex elata All.), which is an active water balance component of subsurface flow constructed wetlands. Due to active regulation of transpiration, the volume and dynamics of water loss in these constructed wetlands are difficult to plan without preliminary and targeted measurements and calculations with regard to the specific plant component. We estimated transpiration values in the laboratory based on daytime transpiration ranges for spring, summer and autumn, and examined the transpiration effect of the hydraulic load. During spring, water loss via transpiration can reach 83% of the hydraulic load on certain days. During summer, this value can increase to 100% of the hydraulic load, which means that the daytime transpiration can significantly affect effluent concentration. Air humidity proved to be the most critical environmental factor for water loss resulting from transpiration, therefore a water discharge plan designed in such a way as to be able to also adjust soil moisture is the key to optimal water circulation at the system level.

Published: June 2019

The application of the anammox process has great potential in treating nitrogen-rich wastewater. The presence of Fe (II) is expected to affect the growth and activity of anammox bacteria. Short-term (acute) and long-term effects (chronic) of Fe (II) on anammox activity were investigated. In the short-term study, results demonstrated that the optimum concentration of Fe (II) that could be added to anammox is 0.08 mM, at which specific anammox activity (SAA) improved by 60% compared to the control assay, 0.00 mM. The inhibition concentration, IC50, of Fe (II) was found to be 0.192 mM. Kinetics of anammox specific growth rate were estimated based on results of the batch test and evaluated with Han-Levenspiel's substrate inhibition kinetics model. The optimum concentration and IC50 of Fe (II) predicted by the Han-Levenspiel model was similar to the batch test, with values of 0.07 mM and 0.20 mM, respectively. The long-term effect of Fe (II) on the performance of a sequencing batch reactor (SBR) was evaluated. Results showed that an appropriate Fe (II) addition enhanced anammox activity, achieving 85% NH4+-N and 96% NO2−-N removal efficiency when 0.08 mM of Fe (II) was added. Quantitative polymerase chain reaction (qPCR) was adopted to detect and identify the anammox bacteria.
Cell Therapy in Solid Organ Transplantation
Authors: Cai Songjie , Chandraker Anil
Published: June 2019

Transplantation is the only cure for end-stage organ failure. Current immunosuppressive drugs have two major limitations: 1) non antigen specificity, which increases the risk of cancer and infection diseases, and 2) chronic toxicity. Cell therapy appears to be an innovative and promising strategy to minimize the use of immunosuppression in transplantation and to improve long-term graft survival. Preclinical studies have shown efficacy and safety of using various suppressor cells, such as regulatory T cells, regulatory B cells and tolerogenic dendritic cells. Recent clinical trials using cellbased therapies in solid organ transplantation also hold out the promise of improving efficacy. In this review, we will briefly go over the rejection process, current immunosuppressive drugs, and the potential therapeutic use of regulatory cells in transplantation.
Cellulose Acetate Nanofibrous Membranes for Antibacterial Applications
Authors: Ma Zhipeng , Lin Xinghuan , Ren Xuehong
Published: June 2019

Background:

N-halamine antibacterial materials have been extensively explored over the
past few decades due to their fast inactivation of a broad spectrum of bacterial and rechargeability.
Electrospun nanofibers loaded with N-halamines have gained great attention because of their enhanced
antibacterial capability induced by the larger specific surface area. The patents on electrospun nanofibers
(US20080679694), (CN2015207182871) helped in the method for the preparation of nanofibers.

Methods:

In this study, a novel N-halamine precursor, 3-(3'-Chloro-propyl)-5,5-dimethylimidazolidine-
2,4-dione(CPDMH), was synthesized. Antimicrobial electrospun Cellulose Acetate
(CA) nanofibers were fabricated through impregnating CPDMH as an antimicrobial agent into CA fibers
by the bubble electrospinning. The surface morphologies of CA/CPDMH nanofibrous membranes
were characterized by Scanning Electron Microscope (SEM).

Results:

The chlorinated fibrous membranes (CA/CPDMH-Cl) exhibited effective antimicrobial activity
against 100% of S. aureus and E. coli O157:H7 within 1 min and 5 min, respectively. The
CA/CPDMH-Cl nanofibrous membranes showed good storage stability under the dark and excellent
durability towards UVA light exposure. Meanwhile, the release of active chlorine from the chlorinated
nanofibrous membranes was stable and safe. Besides, the addition of CPDMH could improve the mechanical
property, and chlorination did not obviously affect the strength and elongation of the nanofibrous
membranes.

Conclusion:

CPDMH could endow the electrospun CA nanofibers with powerful, durable and regenerable
antimicrobial properties. It will provide a continuous and effective method for health-care relative
industrial application.

The chemical investigation of the EtOAc extract of the aerial parts of H. lacteum led to the
isolation of two flavonoids, astragalin (1) and isoquercitrin (2), together with a styryl pyrone,
noryangonin (3), and a cyclobutane dimer, achyrodimer C (4) as well as two triterpenoid compounds,
β-sitosterol (5) and oleanolic acid (6). The highest phenolic and flavonoid contents were detected
in the ethyl acetate extract. Noryangonin exhibited the highest antioxidant activity than those
of the references and all the tested extracts, with a value of IC50 at 1.45±0.44 μg/mL in DPPH scavenging.
In hydrogen peroxide scavenging essay, the results revealed that EtOAc extract exhibited
the highest percent inhibition (63.15 %) as compared to the ascorbic acid (63.36 %) at the concentration
of 100 μg/mL. In the phosphomolybdenum method, the EtOAc extract showed the strongest
activity (36.85±0.02 μg EAA/mg ex) as compared to those of n-BuOH and PE extracts.

Conclusion: :

The antioxidant property shown in these findings needs further investigation, especially
with the pure compound (3).
Digital Media: Life-Changing Online. Introduction
Authors: Brant Clare , Gallagher Rob
Published: June 2019

This special issue follows on from the IABA Europe 2017 conference held at King’s College London hosted by the Ego-Media research group and the Centre for Life-Writing Research, who thank everyone who contributed. The conference theme was “Life Writing, Europe and New Media”: anodyne terms, in the interests of inclusivity, yet their congruence raises some big questions. Is the term life writing sufficiently able to absorb digital and social media as part of its assumed domain? How do offline and online forms of life writing relate to each other? In a global internet age, what if anything is specific to Europe or European practices? And, agonisingly for the hosts in the wake of Brexit, in what ways is it possible for Britain to persist in being European?
Sharing Small Stories of Life and Death Online: Death-writing of the Moment
Authors: Giaxoglou Korina
Published: June 2019

This article discusses public (and semi-public) reactions to death events attracting media and social media attention, described here as spectacular death sharing online. Based on the empirical study of sample cases—predominantly involving the death of white, often young, adults—I show how different kinds of spectacular death events are shared as small stories. I explore the key types of death selected for sharing online, the linguistic and narrative styling of these selections and the networked uptake of the shared stories of life and death. Addressing sharing practices of life and death at these different levels arguably allows an insight into the way the tellability of death is extended in digital time-spaces and its implications for the visibility of death, dying, and mourning. Sharing life and death as small stories of the moment is found to involve practices of death-writing of the moment, which are intimately connected to salient forms of broadcasting the self-online as life-writing of the moment (Georgakopoulou 2017). This mode of sharing offers a window to broader tensions arising from public displays of emotion and the changing—and often antagonistic—forms of testimony in contemporary networked societies.

Authors: Li Zhongjie , Yu Jianxing , Ren Xiang , Ye Chuchu , Tian Keqing , Feng Luzhao , Song Ying , Cowling Benjamin J
Published: June 2019

BACKGROUND

Influenza vaccination is recommended for nurses in China but is not mandatory or offered free of charge. Identifying factors that impact seasonal influenza vaccine acceptance among nurses in China may inform strategies to increase vaccination coverage in this high priority group.

OBJECTIVE

To determine influenza vaccination coverage and the principal factors influencing influenza vaccination among nurses in China.

METHODS

During March 22-April 1, 2018, we conducted an opt-in internet panel survey among registered nurses in China. Respondents were recruited from an internet-based training platform for nurses. We assessed influenza vaccination status and factors influencing influenza vaccine acceptance and refusal.

RESULTS

Among 22,888 nurses invited to participate, 4,706 responded, and 4,153 were valid respondents. Overall, 257 (6%) nurses reported receiving the seasonal influenza vaccine during the 2017/18 season. Vaccination coverage was highest among nurses working in Beijing (10%, P<.001) and nurses working in primary care (12%, P=.023). The top three reasons for not being vaccinated were lack of time (28%), not knowing where and when to get vaccinated (14%), and lack of confidence in the vaccine’s effectiveness (12%). Overall, 41% of nurses reported experiencing at least one episode of influenza-like illness (ILI) during the 2017/18 season; 87% of nurses kept working while sick, and 25% of nurses reported ever recommending influenza vaccination to patients. Compared with nurses who did not receive influenza vaccination in the 2017/18 season, nurses who received influenza vaccination were more likely to recommend influenza vaccination to patients (67% vs. 22%, P<.001).

CONCLUSIONS

Influenza vaccination coverage among nurses was low, and only a small proportion recommended influenza vaccine to patients. Our findings highlight the need for a multi-pronged strategy to increase influenza vaccination among nurses in China.

Published: June 2019

This study examines the issue of the formation of destination image through the analysis of the specific tourism discourse. It is the linguistic variety of English used in tourism which was written by tourists on websites imaging the destination of the Campuhan Ridge. The study focuses on the way tourism discourse contributes to convey an image of a destination using the approach of media exposure theory. Referring to previous scientific studies, tourism destination image have been shaped through the mediation between tourists’ mental constructs and web-based tourism discourse. Using a theory of information media exposure and an approach of linguistic study, samples of texts from websites were examined and analyzed using qualitative content analysis. Results show that linguistic features seen from lexical and phrasal choices were used together with functional attributes, psychological attributes, Psychological-holistic impressions, and Common-Unique dimension when tourists describing about tourism destination image.

RESUMEN: Se estudió la herpetofauna asociada a tres especies de bromelias de tanque en un bosque seco semideciduo sobre carso desnudo en el Parque Nacional Guanahacabibes, Cuba. Se seleccionaron 20 plantas adultas de cada una de las especies de bromelias (Tillandsia utriculata, T. fasciculata, Hohenbergia penduliflora). Determinamos las especies y altura de los árboles en los que las bromelias estaban creciendo. Removimos cada bromelia del árbol y se listaron las especies de anfibios y reptiles que se encontraron. Se calculó la abundancia relativa y el índice de dominancia de cada especie zoológica, y construimos un gráfico de diversidad. Había 34 anfibios y reptiles, de ocho especies (cinco familias). Cuatro especies son endémicas de Cuba (tres anfibios y un reptil). De las bromelias muestreadas 31,67% estaban ocupadas por herpetofauna,  67,65% de los animales se encontraban en T. utriculata. La herpetofauna tiende a preferir las bromelias a 2,31-3,20m de altura. La especie más dominante fue Eleutherodactylus varians (abundancia relativa de 55,88%). Estas bromelias de tanque pueden considerarse como especies clave, su papel es primordial en estos bosques secos semideciduos (fundamentalmente T. utriculata) y los recursos que proporcionan son esenciales para la herpetofauna, particularmente para el anuro endémico E. varians.PALABRAS CLAVE: herpetofauna, Tillandsia utriculata, Tillandsia fasciculata, Hohenbergia penduliflora, anuros, Eleutherodactylus

Maturity size and fecundity of hybrid tilapia Oreochromis aureus X Oreochromis niloticus. (Pisces: Cichlidae) from the reservoir Fernando Hiriart Balderrama “Zimapan”, Hidalgo, Mexico were determined in organisms caught between 2007 and 2008. A total of 506 hybrid fishes were captured and showed a range of sizes from 20 to 28,9 cm standard length (SL), and total weight of 200 to 750g (Tw).  The estimated maturation size for females was 20,8cm and 22cm for males, respectively. Fecundity was estimated on 50 gonads and a mean of 3 113±1 826 eggs was recorded per gravid female. Based on these results, these fishes are suitable for commercial exploitation and imply good conservation in correlation to the regulatory strategies for fisheries established in the area, at least from a reproductive point of view.

Authors: WingChing-Jones Rodolfo , Mora Chaves Esteban
Published: June 2019

Climatic conditions affect milk production in the humid tropics. They have an effect on on somatic cell count (SCC) and total solids (TS), fat, protein (CP) and lactose concentration in milk. We studied these variables in Turrialba, Costa Rica, for 52 weeks between 2009 and 2010. We collected 784 samples (100 ml each) of milk from 19 animals and analyzed them with the FOSS Electric A/S for MilkoScan TM FT 120 Type 71200. Somatic cell count was done with the 400 Series Fossomatic. Temperature affected TS, fat and lac- tose content (p <0.05), precipitation affected the TS and CP content correlated with radiation. Humidity affected SCC, TS, fat and lactose. Within system variables, animal and lactation days are significant for SCC and milk components; calving number was related to fat content, CP and lactose. Age and milk production affect TS, fat, CP and lactose. Month affected TS, CP and lactose content. All variables changed with the year.

The reactivity of dopamine precursors and metabolites towards ABTS•-: An experimental and theoretical study
Authors: Dimic Dusan , Milenkovic Dejan , Markovic Zoran , Dimitric-Markovic Jasmina
Published: June 2019

The antiradical activity of L-3,4-dihydroxyphenylalanine (L-DOPA), dihydroxyphenylacetic acid (DOPAC), homovanillic acid and tyrosine towards 2,2?-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt radical (ABTS?-) was investigated experimentally and theoretically by UV?Vis spectroscopy and the DFT theory. The importance of the catechol moiety for this reaction was proven due to the formation of intramolecular hydrogen bond in the formed anions and radicals. The results indicated L-DOPA and DOPAC were more potent radical scavengers than homovanillic acid and tyrosine just because of intramolecular hydrogen bond formation. Based on experimental spectra, it was proved that electron transfer led to the reduction of ABTS?-. The values of thermodynamic parameters were used to predict the preferred mechanism. The reaction rates were calculated for the electron transfer processes and it was shown that these were both kinetically and thermodynamically driven processes. Based on the reaction rate values, thermodynamic parameters, and present species, as determined by electronic spectra, it was concluded that single proton loss electron transfer (SPLET) is the dominant reaction mechanism in the investigated system.

A systematic review of Flipped Classroom methodology at university level in Spain
Authors: Galindo-Domínguez Héctor , Bezanilla María-José
Published: June 2019

Flipped Classroom is a methodology that is being more common at university level, surely, due to the active role the students take on the learning process. In this research a systematic review of this methodology at university level in Spain is carried out. The analysis of 109 research studies point out the gradual increment of the number of publications about this topic both, in Spanish and English, as time goes by that could be related to an increment of the use of this methodology at university classes. Despite the fact there are few universities that consider this methodology as part of their common praxis, almost half of Spanish Universities have had a preliminary contact with it. The vast majority of these experiences have been applied to social sciences and law area, as well as engineering and architecture, using fundamentally quantitative designs and techniques. The main objectives of these type of research studies were measure the impact on the academic performance and discover the satisfaction of the experience. Although there is not a clear conclusion about the effectiveness of Flipped Classroom on the students’ academic performance, a large amount of research studies points out positive or positive and neutral general conclusions. Finally, in view of this results, recommendations and future research topics are discussed.

Authors: Branco Thaíssa Velloso Castelo , Watanabe Eluiza Alberto de Morais , Alfinito Solange
Published: June 2019

O objetivo da pesquisa foi analisar os fatores que influenciam o consumo de alimentos orgânicos, e sua relação com a intenção de compra e com o comportamento dos consumidores utilizando a Teoria do Comportamento Planejado (TCP). Especificamente, analisou-se a influência da inserção da confiança do consumidor e da consciência saudável na TCP. Foram aplicados 251 questionários junto a consumidores de frutas, legumes e hortaliças orgânicas.  A análise de dados foi feita por meio da Modelagem por Equações Estruturais. Os resultados mostraram que as normas subjetivas, atitude e controle percebido influenciam diretamente a intenção de compra de orgânicos e esta, por sua vez, impacta o comportamento dos consumidores. Em contrapartida, a confiança não foi significativa no modelo de predição. Por fim, a consciência saudável impactou a intenção de compra, mas de forma pouco expressiva. A pesquisa contribui para a diminuição da lacuna de estudos brasileiros sobre o tema e analisa a inserção de mais duas dimensões ao modelo da TCP. Implicações adicionais são discutidas.

Aspek lingkungan, ekonomi dan sosial merupakan tiga pilar penting dalam pembangunan berkelanjutan. Akan tetapi berdasarkan Dokumen Informasi Kinerja Pengelolaan Lingkungan Hidup Daerah (DIKPLHD) Sumatera Barat Tahun 2017 disebutkan timbulan sampah di Sumatera Barat mencapai 2.452.213 kg/hari dan hanya 34,54% kabupaten/kota yang sudah mengelola sampah dengan benar. Sejauh ini penanganan yang dilakukan terhadap sampah lazimnya adalah dengan penumpukan, pengumpulan, dan pengangkutan ke Tempat Pemrosesan Akhir (TPA), sehingga diperlukan upaya mengurangi sampah dengan cara mengolah dan memilah sampah. Salah satu cara yang dapat digunakan adalah pemberdayaan bank sampah. Oleh karena itu, Campus 2 UNAND Payakumbuh melakukan pengabdian kepada masyarakat melalui acara sosialisasi dan pelatihan yang bertema “Menyulap Sampah Menjadi Rupiah” yang tidak lain, bertujuan untuk mendidik masyarakat untuk dapat mereduksi sampahnya. Selain sebagai wujud atas kepedulian terhadap lingkungan, pemanfaatan sampah juga dirasa menjadi modal usaha yang minim budget untuk dijadikan bisnis berkelanjutan Dalam pelatihan ini para peserta dibekali ilmu baru tentang pengelolaan sampah dan pemberian nilai tambah pada sampah koran yang tidak terpakai menjadi barang yang berguna seperti vas bunga.

Equipment has been made to simulate a discrete system vibration of one degree of freedom. The aim is to obtain equipment for learning for students in the field of mechanical vibration. Vibration simulation includes free vibration and forced vibration of discrete system in one degree of freedom. The main parts of this equipment are rigid rods with mass of 2.6 kg, vibrators with mass of  3.385 kg, spring with stiffness of 3738 N/m and loading masses. A rigid rod of 0.775 m in length is supported by a hinge on one end and hung on a spring in another position. The vibrator is rotated by an electric motor and the rotation can be adjusted from 90-1600 rpm. The vibrator is mounted on a rigid object at the position of 0.285 m, 0.385 m, 0.485 m and 0.585 m from the hinge. A spring with stiffness of 3738 N/m is placed on a rigid object at the position of the hinge. The loading masses of 1.08 kg and 2.08 kg are mounted on a rigid beam in a row at the position of 0.685 m from the hinge. For the free vibration experiments, the natural frequency for each position of vibrator is searched experimentally and theoretically. It is found that the results of the two are similar. For the forced vibration experiments, graphs of vibrational responses are constructed in the frequency domain, then the resonance frequencies are compared to the natural frequency results from the free vibration experiment. Apparently the results are very close. This shows that the research equipment made is reliable and can be used as a student learning tool.

The PPCW railroad flatcars is railroad flatcars used to transport container loads with a maximum load capacity of up to 42 tons. In its use, these railroad flatcars are used to transport the cement bags in the pallet arrangement resulting in crack in the bottom frame of the PPCW railroad flatcars structure. The purpose of this analysis is to find out stress value and deformation value that occurred in the railroad flatcars due to the cement bags loading. The analysis process begins with modeling according to the original size of the railroad flatcars which is then followed by providing the support, gravity, loads, and material specifications used. Based on the result of analysis that has been obtained from the load of cement bags of 546,000 N and ratchet lashing of 900,000 N on the frame of PPCW railroad flatcars, we obtained the maximum von Mises stress value of 231.91 MPa arising on the bottom frame of the PPCW railroad flatcars structure as the site of cracking and the maximum total deformation value of 19.526 mm arising in the center of the railroad flatcars. The PPCW railroad flatcars made from SS400 with yield strength value of 245 MPa. Therefore, it was found that the value of stress arising in the railroad flatcars is still in the safe area and is allowed.

Nomes Ficcionais e Nomes Vazios: Crítica à Teoria da Referência sem Referentes de Mark Sainsbury
Authors: Lemos Italo Lins
Published: June 2019

Mark Sainsbury apresentou através da sua teoria da Referência sem Referentes (RSR) um caminho intermediário entre a teoria da referência direta de Stuart Mill e o descritivismo de Frege. A maior virtude da RSR é que ela permite que expressões que contêm nomes vazios (como ‘Vulcano é um planeta que orbita entre o sol e Mercúrio’) sejam ao mesmo tempo inteligíveis e passíveis de ser valoradas como verdadeiras ou falsas. Por outro lado, a partir da distinção que François Recanati (2018) estabelece entre declarações ficcio-nais, metaficcionais e paraficcionais, o objetivo neste artigo é o de argumen-tar que a RSR gera valores de verdade indesejados para as declarações que contêm nomes ficcionais. Como proposta para lidar com o problema, lançamos as linhas gerais da teoria artefactual de Amie Thomasson (1999) e da teoria dos dois modos de predicação de Peter van Inwagen (1977/1983) e Edward Zalta (1983) de modo que os nomes ficcionais são genuínos e referentes a artefatos abstratos.
Facile Synthesis of Formate-Functionalized Graphene Quantum Dots
Authors: Bruce Jonathan , Clapper Jude
Published: June 2019

Graphene quantum dots have proven useful for a variety of applications due to their impressive bandgap tunability, which can be achieved through structural modification methods including edge functionalization and doping. Here, we investigate the functionalization of graphene quantum dots with formate esters using a method of noncatalyzed electrophilic substitution. We also examine the optical and structural properties of these formate-functionalized graphene quantum dots, with the functionalization causing a redshift in absorption consistent with a reduction in bandgap. The findings in this paper have the potential to be used in applications ranging from single photon emission in quantum computing to tunable fluorescence in bioimaging.
