Preference Heterogeneity of Coastal Gray, Green, and Hybrid Infrastructure against Sea-Level Rise: A Choice Experiment Application in Japan
Authors: Omori Yui
Published: August 2021

Coastal zones are bearing the brunt of an increase in the likelihood of extreme events, coupled with sea-level rise (SLR). Conventionally, gray infrastructures, such as seawalls, have been constructed to reduce risks in limited coastal zone spaces. Nature-based approaches, known as green infrastructure, have been used in coastal defense, and their ecosystem-based disaster risk reduction functions (Eco-DRR) have received growing attention. However, both gray and green infrastructure alone have limitations in responding to an ongoing increase in the intensity and frequency of natural hazards. To overcome these issues, hybrid infrastructure, which combine gray and green components, is needed, and they have been receiving growing attention. Meanwhile, a large-scale coastal development requires stakeholder agreement; thus, it is imperative to understand people’s demands and build a consensus between municipalities and coastal citizens in coastal development for long-term resilience. The author administered the online survey across Japan, applying it to the choice experiment, and obtained 840 valid responses. Therefore, this paper clarified the heterogeneities in coastal people’s preferences for coastal ecosystem services provided by gray, green, and hybrid structures in intertidal zones in Japan, recognizing seawalls as gray and coastal pine forests as green infrastructure. Consequently, while coastal citizens acknowledged gray’s coastal defense function, the diverse perceptions toward seawalls for SLR preparation were notable as its scenarios became severe. Another remarkable finding is that nearly 60% of respondents preferred Eco-DRR functions provided by coastal forests with JPY 695 in willingness-to-pay for expanding 100 m in width, even though there are uncertainties in their performances.

Authors: Grieder Christoph , Kempf Katharina , Schubiger Franz Xaver
Published: August 2021

Cultivation of forage mixtures offers several advantages over monocultures, but forage legumes like alfalfa (Medicago sativa L.) are mostly bred in pure stands. Our goal was to assess the extent of accession-by-cultivation system interaction when alfalfa plants are grown in pure stands or in an easily adaptable nursery system together with their companion grasses, thereby determining the system most suitable for selection in mixture. Spaced plants of 50 alfalfa accessions were grown on bare soil as control treatment (CONV), in a sown sward of short growing lawn cultivars of tall fescue (Festuca arundinacea Schreb.) and red fescue (F. rubra L.) (LAWN), and in a sown sward of taller forage cultivars of the same species (FORA). Accession-by-cultivation system interaction variances were large for growth habit but small for vigor. Phenotypic correlation coefficients (rp) among the cultivation systems were high for vigor, whereby LAWN was somewhat more predictive for FORA (rp, FORA−LAWN = 0.83) than CONV (rp, FORA−CONV = 0.77). Observed accession-by-genotype interactions can be used pro or contra necessity for selection in mixture. However, the LAWN cultivation system might be a good compromise for practical breeding, allowing to account for given competition effects among species and to easily assess traits in the nursery.

Heavy metal pollution is still present in the Danube River basin, due to intensive naval and agricultural activities conducted in the area. Therefore, continuous monitoring of this pivotal aquatic macro-system is necessary, through the development and optimization of monitoring methodologies. The main objective of the present study was to develop a prediction model for heavy metals accumulation in biological tissues, based on field gathered data which uses bioindicators (fish) and oxidative stress (OS) biomarkers. Samples of water and fish were collected from the lower sector of Danube River (DR), Danube Delta (DD) and Black Sea (BS). The following indicators were analyzed in samples: cadmium (Cd), lead (Pb), iron (Fe), zinc (Zn), copper (Cu) (in water and fish tissues), respectively, catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), malondialdehyde (MDA) (in fish tissues). The pollution index (PI) was calculated to identify the most polluted studied ecosystem, which revealed that Danube River is seriously affected by the presence of Fe (IP = 4887) and strongly affected by the presence of Zn (IP = 4.49). The concentration of Cd in fish muscle tissue was above the maximum permitted level (0.05 µg/g) by the EU regulation. From all analyzed OS biomarkers, MDA registered the highest median values in fish muscle (145.7 nmol/mg protein in DR, 201.03 nmol/mg protein in DD, 148.58 nmol/mg protein in BS) and fish liver (200.28 nmol/mg protein in DR, 163.67 nmol/mg protein, 158.51 nmol/mg protein), compared to CAT, SOD and GPx. The prediction of Cd, Pb, Zn, Fe and Cu in fish hepatic and muscle tissue was determined based on CAT, SOD, GPx and MDA, by using non-linear tree-based RF prediction models. The analysis emphasizes that MDA in hepatic tissue is the most important independent variable for predicting heavy metals in fish muscle and tissues at BS coast, followed by GPx in both hepatic and muscle tissues. The RF analytical framework revealed that CAT in muscle tissue, respectively, MDA and GPx in hepatic tissues are most common predictors for determining the heavy metals concentration in both muscle and hepatic tissues in DD area. For DR, the MDA in muscle, followed by MDA in hepatic tissue are the main predictors in RF analysis.

Published: August 2021

South Korea has operated under laws to collect and recycle the waste of electrical and electronic equipment (WEEE) utilizing a system based on the Extended Producer Responsibility (EPR) system since 2003. In 2020, the number of products managed by the EPR increased from 27 to 50. Among the 50 products, massage chairs and treadmills are recognized as the items avoided in recycling centers or by recyclers due to their large volume, large weight, and long disassembly times. This study was a preliminary study in which the physical shredding process for massage chairs and treadmills could be introduced, and the electrical power requirements calculated. In the methodology, Vickers hardness was measured by sampling two actual products, and the tensile and shear strength were calculated from the hardness. Based on the shear strength, the force affecting the cutter was calculated and converted into torque and horsepower. In particular, the actual specifications of the crusher, designed and operated in the recycling center, were applied to the study, and the design was based on the treatment capacity of 10 tons per hour. Conclusively, the proper electrical power for crushing the massage chair and treadmill was analyzed as 719.5 and 459.7 HP, respectively.

Published: August 2021

Ceria- and urea-doped activated biochars were used as support for Ni-based catalysts for CO2 methanation purposes. Different materials were prepared and tested to find the best catalytic formulation. After several CO2 methanation experiments—carried out at 0.35–1.0 MPa and 300–500 °C—it was found that the most suitable catalyst was a wheat-straw-derived activated biochar loaded with 30 wt.% of CeO2 and 20 wt.% of Ni. Using this catalyst, a CO2 conversion of 65% with a CH4 selectivity of 95% was reached at 1.0 MPa, 400 °C, and 13,200 h−1. From the study of the influence of the gas hourly space velocity, it was deduced that the most likely reaction mechanism was a reverse water–gas shift reaction, followed by CO hydrogenation. N-doping of the carbon support as an alternative to the use of ceria was also investigated. However, both CO2 conversion and selectivity toward CH4 values were clearly lower than those obtained for the ceria-containing catalyst cited above. The outcomes of this work indicate that a renewable biomass-derived support can be effectively employed in the catalytic conversion of CO2 to methane.

Published: August 2021

Pesticides are a major problem not only in the food chain but also when considering the protection of our planet. The use of neonicotinoids has been banned in the EU due to their high toxicity to living organisms, in particular honeybees. The presence of neonicotinoids in natural waters poses a threat to pollinating insects and thus hampers organic production. Pesticide residues in the natural waters of agricultural land are monitored within the framework of promoting sustainable rural development to maintain the safety of human and animal health. Chromatographic analyses of selected neonicotinoid pesticides in water samples from agricultural sites in eastern Poland were performed using high performance liquid chromatography (HPLC), which followed a solid-phase extraction (SPE). The research revealed no evidence of neonicotinoids contamination. Water quality in this region can be a good factor in promoting sustainable development. The obtained results complement the existing knowledge on the impact of neonicotinoids on both the sustainable food chain and the environment. Based on the results obtained, it is possible to conclude that they are not being used in rural area under the study.

Authors: Behrendt Frauke , Cairns Sally , Raffo David , Philips Ian
Published: August 2021

Electrically-assisted cycling can make a major contribution to sustainable mobility. For some people, hills are a barrier for cycling. This paper focuses on how and why electrically-assisted bikes make a difference to cycling in hilly contexts, and can thus be an important element of sustainable mobility in hilly geographies. It makes a novel contribution in being able to draw on recorded sensor data of the actual use of assistance in relation to the specific geography of the route cycled (GPS data), and interview/survey material. It shows that e-bikes extend the range, nature and scope of journeys manageable by bike, and therefore the general viability of e-bikes as alternative to other modes. It highlights that the benefits of using e-bikes are often also psychological, since they can change the overall enjoyability of the cycling experience in hilly areas. Resulting policy recommendations, that could lead to significant CO2 savings through the uptake of e-cycling in hilly contexts, include ‘try before you buy’ schemes, training for e-bike users and investing in relevant cycling infrastructure.
Predicting the Intention to Donate Blood among Blood Donors Using a Decision Tree Algorithm
Authors: Salazar-Concha Cristian , Ramírez-Correa Patricio
Published: August 2021

The blood donation process is essential for health systems. Therefore, the ability to predict donor flow has become relevant for hospitals. Although it is possible to predict this behaviour intention from donor questionnaires, the need to reduce social contact in pandemic settings leads to decreasing the extension of these surveys with the minimum loss of predictivity. In this context, this study aims to predict the intention to give blood again, among donors, based on a limited number of attributes. This research uses data science and learning concepts based on symmetry in a particular classification to predict blood donation intent. We carried out a face-to-face survey of Chilean donors based on the Theory of Planned Behaviour. These data, including control variables, were analysed using the decision tree technique. The results indicate that it is possible to predict the intention to donate blood again with an accuracy of 84.17% and minimal variables. The added scientific value of this article is to propose a more simplified way of measuring a multi-determined social phenomenon, such as the intention to donate blood again and the application of the decision tree technique to achieve this simplification, thereby contributing to the field of data science.

Published: August 2021

Three-finger toxins (3FTXs) are the most clinically relevant components in cobra (genus Naja) venoms. Administration of the antivenom is the recommended treatment for the snakebite envenomings, while the efficacy to cross-neutralize the different cobra species is typically limited, which is presumably due to intra-specific variation of the 3FTXs composition in cobra venoms. Targeting the clinically relevant venom components has been considered as an important factor for novel antivenom design. Here, we used the recombinant type of long-chain α-neurotoxins (P01391), short-chain α-neurotoxins (P60770), and cardiotoxin A3 (P60301) to generate a new immunogen formulation and investigated the potency of the resulting antiserum against the venom lethality of three medially important cobras in Asia, including the Thai monocled cobra (Naja kaouthia), the Taiwan cobra (Naja atra), and the Thai spitting cobra (Naja Siamensis) snake species. With the fusion of protein disulfide isomerase and the low-temperature settings, the correct disulfide bonds were built on these recombinant 3FTXs (r3FTXs), which were confirmed by the circular dichroism spectra and tandem mass spectrometry. Immunization with r3FTX was able to induce the specific antibody response to the native 3FTXs in cobra venoms. Furthermore, the horse and rabbit antiserum raised by the r3FTX mixture is able to neutralize the venom lethality of the selected three medically important cobras. Thus, the study demonstrated that the r3FTXs are potential immunogens in the development of novel antivenom with broad neutralization activity for the therapeutic treatment of victims involving cobra snakes in countries.
Cytochrome P450 Monooxygenases CYP6AY3 and CYP6CW1 Regulate Rice Black-Streaked Dwarf Virus Replication in Laodelphax striatellus (Fallén)

Published: August 2021

The small brown planthopper, Laodelphax striatellus (Fallén), is an important agricultural pest that causes significant losses by sucking and transmitting multiple plant viruses, such as rice black-streaked dwarf virus (RBSDV). Insecticides are commonly used to control planthoppers and cause the induction or overexpression of cytochrome P450 monooxygenases (P450s) from the CYP3 and CYP4 clades after insecticide application. However, little is known about the roles of insecticides and P450s in the regulation of viral replication in insects. In this study, RBSDV-infected L. striatellus were injected with imidacloprid, deltamethrin, pymetrozine, and buprofezin, respectively. The insecticide treatments caused a significant decrease in RBSDV abundance in L. striatellus. Treatment of piperonyl butoxide (PBO), an effective inhibitor of P450s, significantly increased the RBSDV abundance in L. striatellus. Fourteen P450 candidate genes in the CYP3 clade and 21 in the CYP4 clade were systematically identified in L. striatellus, and their expression patterns were analyzed under RBSDV infection, in different tissues, and at different developmental stages. Among the thirty-five P450 genes, the expression level of CYP6CW1 was the highest, while CYP6AY3 was the lowest after RBSDV infection. Knockdown of CYP6CW1 and CYP6AY3 significantly increased the virus abundance and promoted virus replication in L. striatellus. Overall, our data reveal that CYP6CW1 and CYP6AY3 play a critical role in the regulation of virus replication in L.striatellus.

Various organizations and institutions store large volumes of tsunami-related data, whose availability and quality should benefit society, as it improves decision making before the tsunami occurrence, during the tsunami impact, and when coping with the aftermath. However, the existing digital ecosystem surrounding tsunami research prevents us from extracting the maximum benefit from our research investments. The main objective of this study is to explore the field of data repositories providing secondary data associated with tsunami research and analyze the current situation. We analyze the mutual interconnections of references in scientific studies published in the Web of Science database, governmental bodies, commercial organizations, and research agencies. A set of criteria was used to evaluate content and searchability. We identified 60 data repositories with records used in tsunami research. The heterogeneity of data formats, deactivated or nonfunctional web pages, the generality of data repositories, or poor dataset arrangement represent the most significant weak points. We outline the potential contribution of ontology engineering as an example of computer science methods that enable improvements in tsunami-related data management.
An Evaluation of a New Scheme for Determination of Irrigation Depths in the Egyptian Nile Delta
Authors: Abd El Baki Hassan M. , Fujimaki Haruyuki
Published: August 2021

Innovative irrigation techniques should be implemented to improve irrigation management in dryland countries. In this regard, a new scheme, that uses three sets of irrigation depth and numerically simulated cumulative transpiration, was evaluated in the Egyptian Nile delta in 2020. Presuming that water is volumetrically priced, the proposed scheme can maximize net incomes at optimum irrigation depths considering quantitative weather forecasts. A field experiment was carried out with a randomized complete block design using a major crop, maize, to assess the feasibility of the proposed scheme in comparison to a sensor-based irrigation method under conditions of dry climate and clay loamy soil. The proposed scheme could increase the gross net income of farmers and conserve irrigation by 21% and 35%, respectively, compared to a sensor-based irrigation method, although the yield and its components were almost the same with no significant statistical differences. The model could accurately simulate soil water content in the topsoil layers with a RMSE of 0.02 cm3 cm−3. The proposed scheme could be a useful tool to spare the costs of expensive soil monitoring sensors while saving water and improving net income.
Binding of Calcium and Magnesium Ions to Terrestrial Chromophoric Dissolved Organic Matter (CDOM): A Combination of Steady-State and Time-Resolved Fluorescence Study
Authors: Liu Juan , Zhou Ruiya , Zhang Xu
Published: August 2021

Revealing the binding properties of calcium ion (Ca2+) and magnesium ion (Mg2+) to terrestrial chromophoric dissolved organic matter (CDOM) facilities understanding the effect of natural water components on the photophysics of dissolved organic matter. Steady-state and time-resolved fluorescence spectrometry, and dynamic light scattering were applied to investigate the fluorescence quenching process of CDOM by Ca2+ and Mg2+. Due to a remarkable decrease of the steady-state fluorescence intensity and a slight decrease of fluorescence lifetime, the fluorescence quenching of CDOM by cations mainly occurred through a static process. The fluorescence quenching was profound under longer excitation and emission wavelengths. The binding constant (K, L/mol) for Ca2+ to CDOM ranged from 4.29 to 5.09 (lgK), which was approximately one order of magnitude higher than that of Mg2+ to CDOM (3.86 to 4.56). Nevertheless, the efficiency of CDOM fluorescence quenching by Ca2+, Mg2+ was much lower than that by Cu2+. Fluorescence decay became faster in the presence of a high concentration of Ca2+ (>20 mg/L) and Mg2+ (>50 mg/L). In the presence of these two metal ions, particularly for Ca2+, the lifetime of CDOM excited states shifted to the relatively small value side, indicating fluorescence quenching of CDOM mainly occurred through the interaction of Ca2+/Mg2+ with relatively long-lived fluorophores.
Comparative Use of Hydrologic Indicators to Determine the Effects of Flow Regimes on Water Quality in Three Channels across Southern Florida, USA
Authors: Onwuka Ikechukwu S. , Scinto Leonard J. , Mahdavi Mazdeh Ali
Published: August 2021

This study determines the relationships between water flow and water quality in three types of channels in southern Florida, USA: Shark River Slough, Peace River, and Hillsboro Canal. Peace River most resembles a natural channel with floodplain connectivity, sinuosity, and uninhibited flow. Shark River Slough has a natural, shallow channel with sheet flow, while the Hillsboro Canal is the most modified channel due to dredging, straightening, and regulated flow. Hydrologic indices for each channel were estimated to characterize flow regimes and flow variability, while concentration–discharge (C–Q) relationships were determined to quantify the impact of flow regime on water quality. The greatest variability in flow occurred at the Hillsboro Canal, followed by Peace River and Shark River Slough. Connectivity to floodplains and long durations of low and high flow pulses at Peace River and Shark River Slough contributed to the dilution of water quality constituent concentrations at higher flows. Conversely, the channelized characteristics of the Hillsboro Canal resulted in an enrichment of constituents, especially during high flows. This study suggests that C–Q relationships can be used in canal discharge management to prevent water quality degradation of sensitive downstream wetland and aquatic ecosystems.

Published: August 2021

The use of traditional genetic characterization techniques for detection of genetic variation in aquatic species based on morphological characters has its own limitations. One of the modern approaches to study genetic variation in aquatic species is by Restriction Fragment Length Polymorphism (RFLP) of mitochondrial DNA (mtDNA). Amplification of mitochondrial 12s and 16s rRNA genes from tiger shrimp (Penaeus monodon, Penaeidae), white shrimp (Fenneropenaeus indicus, Penaeidae), grey mullet (Mugil cephalus, Mugilidae), tilapia (Oreochromis mossambicus, Cichlidae), Asian sea bass (Lates calcarifer, Centropomidae) and mud crabs (Scylla serrata and Scylla tranquebarica, Portunidae) and the characterization of the amplified PCR products by RFLP have been carried out in the present study. The use of the primers in the present study was found to be universal for amplification of mitochondrial 12s and 16s rRNA genes across the taxonomically different brackishwater species examined in this investigation. The amplified products of 12s and 16s rRNA mitochondrial gene segments obtained with these primers can be used for restriction digestion as an approach to obtain species-specific markers by PCR-RFLP analysis.
Identification of Species-Marker Bands in Native and SDS-PAGE Patterns of Soluble Muscle Proteins of Four Species of Genus Channa (Channidae: Channiformes) with Evidence of Some Intraspecies Heterogeneity

Published: August 2021

Soluble proteins of skeletal muscles of four species of genus Channa have been analyzed by native and SDS-containing polyacryalmide gel electrophoresis (SDS-PAGE). Native-PAGE patterns of soluble skeletal muscle proteins of all four species are devoid of intraspecies qualitative variations. Sixteen protein bands, each with characteristic electrophoretic mobility, are diagnostic to Channa gachua and C. striatus, while 10 and 15 bands are to C. marulius and C. punctatus, respectively. In the same sequence of species, the total number of representative polypeptides in SDS-PAGE patterns is: 18, 14, 13 and 21, respectively. Among species-marker bands, highly acidic proteins are most prominent. Species specific polypeptides have also been identified after resolving soluble muscle proteins by SDS-PAGE. Intraspecies quantitative differences within the individual bands exist in native as well as SDS-PAGE systems; but, contrary to native electrophoretic system, SDS-PAGE patterns of the soluble muscle proteins display a certain degree of numerical heterogeneity also. Most obvious differences are observed in polypeptides with in the Mr range of 26-44 kD, which could be placed under variability-groups of consistency. Identified species-marker bands resolved in either of the electrophoretic systems can also be used for identifying the hybrids and settling taxonomic controversies. In order to facilitate the use of data by other workers, the molecular weights of each band in SDS-PAGE and the relative electrophoretic mobilities of species marker patterns in native gels have been documented.
Effect on Breeding Performance and Egg Quality of Clarias batrachus (Linn.) at Various Doses of Ovatide During Spawning Induction
Authors: SAHOO S.K. , GIRI S.S. , SAHU A.K.
Published: August 2021

An experiment was conducted to evaluate Ovatide doses (0.5, 1.0, 1.5 and 2.0 ml·kg body weight of female) on breeding performance and egg quality of Clarias batrachus. The breeding performance was judged on the basis of the total weight of stripped eggs, spawning fecundity and stripping response. To judge the egg quality, the per cent fertilization, hatching, deformity and normal larvae were considered. The results indicated that the total weight of stripped eggs and spawning fecundity were the highest (p < 0.05) when females were injected 1 ml of Ovatide per kg body weight (BW) compared to those injected with other dose levels. The lowest stripping response was observed with injection of 0.5 ml Ovatide per kg BW. There was difficulty in stripping at 0.5, 1.5 and 2.0 ml doses, but at 1 ml dose, it was smooth. At the 1 ml dose, the percentages of fertilization and hatching were 83 and 71 % respectively, which were the highest (p < 0.05) among all treatments. Increasing Ovatide doses above 1 ml led to over ripening of ova, which resulted in increased per cent deformed larvae. More normal larvae were produced from the females when injected the 1 ml dose. One ml of Ovatide per kg body weight was found optimum for best breeding performance and egg quality in C. batrachus.

El número actual de Teoría y Práctica de la Arqueología Histórica Latinoamericana está enfocado desde la perspectiva de los estudios de casos puntuales, demarcando tanto las posibilidades que ofrece el espectro de sitios arqueológicos en esta disciplina como las características metodológicas que despliegan sus investigadores. Así, el lector pude aproximarse a la arqueología

de templos, cementerios, fábricas, explotaciones de lobos marinos, establecimientos rurales, antiguos espacios de frontera, patrimonio funerario en una ciudad y situaciones históricas de conflictos locales. ¿Se puede inferir que la naturaleza de los registros se dispersa?. No necesariamente: expresa su versatilidad.

En este segundo volumen del año 2021 presentamos una serie de artículos que formaron parte de las presentaciones del IX Simposio de Arqueología Histórica Latinoamericana realizado de manera virtual en noviembre del 2020. Se exponen estudios sobre registros materiales y documentales que problematizan espacios fronterizos y rurales, estancias, paisajes industriales, ciudades y cementerios en marcos temporales que abarcan desde el periodo colonial hasta el inicio del siglo XX. Se presenta, además, el tratamiento patrimonial de un templo colonial declarado oportunamente Monumento Histórico Nacional.

En este artículo se presentan las principales líneas de trabajo y actividades desarrolladas por este grupo de investigaciones recientemente conformado que nuclea a investigadores de distintas disciplinas e instituciones. El eje común de todos los proyectos se centra en abordar el proceso de avance y construcción de las fronteras del Imperio Español (en el período colonial) y del Estado (etapa post-independentista) en interacción con las sociedades indígenas en la región pampeana-norpatagónica hasta la conquista militar de fines del siglo XIX. A través de identificar e interpretar los distintos mecanismos materiales, institucionales y simbólicos desplegados por la Corona, el Estado y parte de la población eurocriolla, buscamos comprender las transformaciones espaciales y paisajísticas del territorio que conformó dicho espacio fronterizo y rural. El conjunto de proyectos se caracteriza por presentar novedosas técnicas de detección de sitios y líneas analíticas en el estudio de la cultura material. Asimismo, hemos desarrollado diversas actividades de divulgación científica y de extensión hacia y con las comunidades a distintas escalas -locales, regionales, nacionales e internacionales-. Entre éstas destacamos charlas, talleres, elaboración de material educativo y acompañamiento a las comunidades involucradas en las áreas de trabajo así como acciones en conjunto referidas al cuidado del patrimonio arqueológico. Desde la arqueología histórica, con la integración crítica de distintos tipos de registros, buscamos realizar aportes al conocimiento arqueológico e histórico, local y regional, sobre el complejo y vigente tema de las fronteras.

Inspired by the ideas of many authors, we provide insight on state-of-the-art potential technologies for the prevention and prediction of infectious diseases before they spread. This review also surveys virus sterilization with ultraviolet light and low temperature plasma technologies. Researchers in the various fields of medicine, materials, electronics, and plasma sciences have addressed increasingly challenging demands and the discussion encompasses the major challenges in societies that are faced with the threat of infectious diseases. In addition, technologies that use nanomaterials are evaluated for infection prevention and hygiene purposes. Advances in biomedical diagnostics for health care in terms of complementary metal-oxide-semiconductor transistors-based devices and telemetry for health monitoring are also reviewed.
Colloidal solution of boron and phosphorus codoped silicon quantum dots—from material development to applications
Authors: Fujii Minoru , Sugimoto Hiroshi , Kano Shinya
Published: August 2021

A core/shell silicon (Si) quantum dot (QD) composed of a crystalline Si core and an amorphous shell, in which boron (B) and phosphorus (P) are very heavily doped, is developed. Because of the amorphous shell, the B and P codoped Si QDs exhibit significantly different physical and chemical properties from undoped ones. The codoped Si QDs are dispersible in polar solvents such as water and alcohol without organic ligands and exhibit stable luminescence in water. Because of the superior properties, the codoped Si QDs have applications in different fields including photonics, biophotonics, photochemistry and electronics. In this article, we discuss the structure and optical and electrical properties of the codoped core/shell Si QDs and show the application potentials in different fields.

Published: August 2021

O fato do câncer de colo de útero ser o terceiro câncer que mais acomete o público feminino e promove sequelas inestimáveis, faz-se necessária a coleta de exame preventivo para rastreamento da doença, a fim de evitar um desfecho fatal. O Ministério da Saúde promove uma campanha nacional anual de prevenção, que ocorre no mês de outubro. Assim, foi realizado um levantamento epidemiológico de exames realizados no município de Cascavel-PR, no ano de 2018, para confrontar os dados da campanha com os demais meses do ano. Foram realizados 21.209 exames no ano e, somente no mês da campanha (outubro), foram realizadas 4.129 coletas. Esse período específico produziu 2,5 a 4 vezes mais exames em comparação com o restante de 2018. Isso demonstra a importância do movimento de rastreio, porque são realizados muito mais exames preventivos nesse período que nos demais meses do ano.

Published: August 2021

A dispneia é um sintoma muito prevalente na cardiologia, mas que pode se originar de diferentes síndromes concomitantemente, como no derrame pericárdico e como equivalente anginoso na doença arterial coronariana. Fazer o diagnóstico diferencial das síndromes que a ocasiona pode ser difícil, por isso uma boa anamnese, exame físico, exames laboratoriais e de imagem são fundamentais para uma identificação precisa e para a melhor escolha de abordagem. Isso deve ser feito de forma interdisciplinar, abrangendo todas as áreas da medicina que se identificam com as comorbidades do paciente, para que este tenha a melhor recuperação possível. Este relato aborda uma paciente com dispneia originada por duas síndromes diferentes e acompanhada na cidade de Cascavel-PR.
The Pandemic of the E-Human Movement
Authors: Rammal Julie
Published: August 2021

The movement's evolution and change have strikingly shut down gyms, health clubs, fitness classes, live, personal training jobs, and more during the pandemic. The massive shift has opened up live streaming and online classes; however, we may be soon facing a new body and mind pandemic if we are not aware of the side effects. The longer we are away from socializing and being trained with technique and form, the human body will later experience a separation between body, mind, and soul with dormant emotions and feelings. . In fact, the mind and memory may start to decrease, and focus and discipline will fade. Through the Holistic methodology, we can re-ignite the human being and preserve the humans to continue moving, healing, breathing in a language that the body understands.
Pancreatitis aguda recurrente secundaria a síndrome de arteria mesentérica superior
Authors: Molina Kevin
Published: August 2021

El síndrome de arteria mesentérica superior es caracterizado por la compresión de la tercera parte del duodeno por la arteria mesentérica superior. Más comúnmente se debe a anormalidades congénitas y a pérdida del tejido adiposo intraabdominal. En individuos sanos, este tejido adiposo desplaza la arteria mesentérica superior hacia la aorta, evitando así la compresión del duodeno. La causa de pancreatitis es por un síndrome post papilar obstructivo, con reflujo retrogrado de bilis hacia el conducto pancreático, lo cual activa los fenómenos inflamatorios de la pancreatitis. Presentamos el caso de una mujer de 18 años de edad con diagnóstico de pancreatitis recurrente por síndrome de arteria mesentérica superior.

Las neumonías persistentes o recurrentes pueden ocurrir en pacientes pediátricos. Son indicación para llevar a cabo una broncoscopía diagnóstica, ya que a veces la causa de la patología recurrente puede no ser infecciosa. Este es el caso de un paciente con sintomatología respiratoria recurrente, a quién se le diagnosticó una neumopatía por reflujo, como resultado de incompetencia del hiato esófago gástrico y su caso fue resuelto con una fundo duplicatura de Nissen.
