Evolution of Dry and Wet Spells Under Climate Change Over North‐Eastern North America

Risks associated to extreme hydrological conditions, such as floods and droughts, are expected to increase in future climate because of projected changes in precipitation and temperature. Assessing how wet and dry persisting conditions (or spells) will evolve in future climate is a crucial step in the study of extreme hydrological events. Projected changes over the north‐eastern part of North America in the annual number of wet days, wet, and dry spells characteristics (number, duration), and wet spells intensities are analyzed. Two regional climate model ensembles are considered: the multimember ensemble from the Canadian RCM v5 (CRCM5‐LE), and 16 simulations from the NA‐CORDEX multimodel ensemble both using the Representative Concentration Pathway 8.5 (RCP8.5) scenario. Comparison of observed and simulated wet and dry spells characteristics is first performed in present climate (1971–2000). Regional Climate Model (RCM)s tend to generate too many wet days and wet or dry spells resulting in shorter dry spells and slightly longer wet spells. Modeling uncertainties are accounted for a bigger contribution to the bias than internal variability since the multimodel ensemble dispersion is the largest. Throughout the 21st century, both ensembles project significant trends in winter at higher latitudes resulting in increasing wet day frequency, increasing number of wet spell, longer wet spells and shorter dry spells. For other seasons, internal variability of the CRCM5‐LE and differences among the various NA‐CORDEX simulations seems to overwhelm the climate change signal. Wet spell intensities increases are projected for all seasons over almost the entire domain. Globally, wetter climate with potential significant hydrological impacts are expected in many regions.
Millennial‐Scale Changes in Bottom Water Temperature and Water Mass Exchange Through the Fram Strait 79°N, 63‐13 ka

The Svalbard margin, in the eastern Fram Strait with its high sediment accumulation, form a key area for the reconstruction of water mass and heat exchange between the North Atlantic and Arctic Ocean in relation to abrupt climate changes as seen in glacial Greenland Interstadial and Greenland Stadial (GI‐GS) events. Here, we present a bottom water temperature (BWT) record from the northern Nordic Seas (79°N) at 1,273 m water depth based on benthic foraminiferal Mg/Ca. The BWT reconstructions, combined with benthic foraminiferal stable isotopes, benthic foraminiferal fauna compositions and ice‐rafted debris (IRD), reveal at least two distinctive scenarios for the GI‐GS events during the last glacial period (13–63 ka). During GIs, conditions were similar to modern with high productivity, low BWT and deep convection. During GS6, GS8, and GS15 and during Heinrich Stadials (HSs), BWT increased up to 5°C ± 1°C generally concomitant with low planktic and benthic δ18O. Our results suggest, that during some GSs and HSs, deep water generation was reduced, allowing the subsurface Atlantic water (AW) to thicken and deepen down to at least the core site depth. A strong halocline during HSs and GSs prevented heat release from the subsurface AW, which we can now trace from 45°N in the North Atlantic to the Arctic Ocean >79°N. Surfacing of the salty Atlantic subsurface water preconditioned the Nordic seas for convection. Release of the subsurface heat from this vast reservoir must have contributed to the large and abrupt atmospheric warmings at the start of GIs.
The anti-ageing secret of massively multiplayer online game: Managing its lifecycle

It is estimated that from 2015 to 2025, the Global Multiplayer Online Game (MMOG) market will be growing at a compound annual growth rate of 10.2%. However, rapid market changes have shortened the lifespan of many MMOGs. This market phenomenon may demotivate prospective market players and thus decelerate the market growth. To address the lifespan issue, we conducted a netnographic case study on ‘TalesRunner’, which has successfully operated for longer than many other MMOGs. Based on the data from over 5.2 million messages from its official forum, as well as data from different secondary sources, we established a lifecycle model of MMOG in conjunction with the Technology-Organization-Environment (TOE) framework and offered theoretical implications for both MMOG and lifecycle theory.

An Attention Enhanced Cross-Modal Image-Sound Mutual Generation Model for Birds

Cross-modal bird image–audio mutual generation has appealing potential benefits for bird classification. To achieve promising cross-modal bird visual–audio mutual generation, we propose an attention enhanced cross-modal cycle adversarial generation network. Specifically, the attention module endows our model with long-term intra-modality dependency and inter-modality dependency capabilities, which can provide more information during the generation process and further improve the generation performance. Moreover, because there was no dataset concerning bird visual–audio mutual generation, the authors established a novel bird cross-modal generation dataset, called Bird_Crossmodal_Generation (BCG). Based on BCG, our model obtains promising performance and achieves significant improvement under both inception score and Frechet inception distance criteria. The experimental results validate the feasibility of the proposed task and the superiority of our model. Additionally, this investigation provides a basis for more researchers to develop cross-modality methods for bird visual–audio generation.
Study of Quality and Safety Parameters of Phytobiotics Based on Medicinal Plant Extracts

Organoleptic, physico-chemical, microbiological and hygienic parameters of phytobiotics based on water-ethanol extracts of medicinal plants were studied. It is proved that the mass fraction of moisture in phytobiotics based on extracts of medicinal plants is from 5.5 to 9.3%. the mass fraction of insoluble substances in water is from 1.2 to 4.25, which in terms of physical and chemical parameters correspond to the values specified in the regulatory documentation. From the data obtained, it follows that cmafaim are from 1.7 * 104 to 3.4·104 CFU / cm3 (g), yeast and mold (in total) are 5-9 CFU/g (cm3). it is established that the content of lead, copper, cadmium and zinc in phytobiotics based on extracts of medicinal plants does not exceed the values specified in the regulatory documentation. It is recommended to use phytobiotics based on extracts of medicinal plants as a feed additive for farm animals and poultry.
The Role of Stratigraphy and Loading History in Generating Complex Compaction Bands in Idealized Field‐Scale Settings

The Buckskin Gulch locality in Utah is a landmark example of compaction localization. The outcrop of this locality involves distinct stratigraphic heterogeneity and was exposed to complex loading history. It features multiple sets of deformation bands with different kinematics and orientation. Similar formations were seen in the Valley of Fire, Nevada, and the Orange quarry, France, among other localities. The formation of such complex structures, their propagation mechanisms, and frequency is affected by numerous local and ambient factors whose impacts are not yet fully understood. The simulation of the above‐mentioned localities is not feasible because of the limited amount of available information. This work, instead, investigates from a geomechanics standpoint how the interplay among material nonlinearity, outcrop stratigraphy, and loading history interconnects with specific spatiotemporal patterns of compaction band propagation. Our study shows that the system stratigraphy can be responsible for the emergence of coexisting compaction bands with different inclination and kinematics. Specifically, we show that stiffness contrasts induce nonlocal stress changes which may favor the initiation of secondary structures with different compaction localization characteristics. Furthermore, systems of inclined compaction bands induced by burial increase display secondary, noncontemporaneous sets of vertical compaction bands under the effects of postburial shortening. Our results indicate that stages of intermediate burial decrease prior to tectonic shortening can promote the formation of such complex systems. Despite the simplifications involved in our analyses, these findings show how geomechanics computations complement field observations and could provide a mechanics‐based validation of site‐specific reconstruction hypothesis.
Effect of Etching Time Variation on Porous Si of SERS Substrate for NS1 Detection

Dengue is a major international public health issue. Since 2015, approximately more than 100,000 reported cases with roughly 200 fatal cases are reported yearly in Malaysia. Early detection of infection during the first five days is crucial for monitoring patients to help in reducing the fatality rate. Dengue virus nonstructural 1 (DENV NS1) protein has gained a lot of interest as an early biomarker for diagnosis of DENV infection. Currently, the presence of NS1 is detected through enzyme-linked immunosorbent assay (ELISA) and immuno-chromatographic (ICT) rapid test kit using patients' blood samples which is invasive and prone to blood infection risks. Interestingly, NS1 is also discovered in saliva but at much lower sensitivity performance at ∼64.7% due to its low concentration. In this study, an ultra-sensitive and specific technique known as Surface-Enhanced Raman Spectroscopy (SERS) is proposed for the detection of low concentration of NS1 in saliva. However, SERS performance is highly dependent on the SERS substrate to be used. In this study, electro-chemical etching technique is employed to fabricate porous silicon (porous Si) with variation in structural features served as the SERS substrate base. The focus of this paper is to report on the structural variation of porous Si due to the different etching time duration. Surface characterization of the sample is investigated through the Field Emission Scanning Electron Microscope (FESEM) and energy-dispersive X-ray spectroscopy (EDX). From the top-view, cross-shaped structures are observed, while from the cross-sectional view, triangle-shaped structures are observed. The size of the formed structure increases as etching time increases. However, at the etching time of 30 min, the constructed structure starts to connect with the neighboring structure producing uneven porous Si.
Extration, identification and stability ananlysis of anthocyanins from organic Guizhou blueberries in China

Blueberries are the health fruit of the 21st century, and they are gaining popularity as consumers demand healthier, more nutritious food products. Organic Majiang blueberries are a specialty of Guizhou Miao and Dong autonomous county and are one of China’s national geographical indication products. In the first year of the 13th Five-year Plan, Guizhou Province proposed the “Great poverty alleviation”, “Big Data”, and “Great Health” as three big development strategies; the “great health” strategy covers pharmaceutical plant cultivation, drug development, health food, health tourism, health services, and other fields. Blueberries were rated as one of the five human health foods by the Food and Agriculture Organization of the United Nations, and Majiang County in Guizhou Province cultivate blueberries with advantageous geographical conditions because it is located in a humid subtropical monsoon climate zone with no cold winter sand hot summers, abundant rainfall, and an annual average temperature of 14~16 °C, so it is very beneficial to blueberry cultivation. Blueberries contain rich nutrients; in addition to protein, fat, carbohydrates, vitamin A, vitamin C, vitamin E, superoxide dismutase (SOD), Ca, P, Mg, Zn, Fe, Cu, etc., polyphenols, anthocyanins and phenolic acids are the main components of blueberry polyphenols and have good antioxidant activity and scavenging effects on reactive oxygen species in cells (Thomasset et al., 2009; Urias-Lugo et al., 2015). Blueberries have high anthocyanin contents and contain several anthocyanins (Hu et al., 2006; Mikulic-Petkovsek et al., 2012), such as delphinium, cornflower pigment, petunia pigment, peony anthocyanin, and mallow pigment (Chorfa etal., 2016). However, anthocyanins are particularly unstable in nature and combine with different monosaccharides, disaccharides, trisaccharides and other compounds to form anthocyanin compounds in plants. Therefore, anthocyanins in nature exist in the form of anthocyanin complexes.

On dispersion relation for Faraday waves in a near-critical fluid under weightlessness

One reports experiments and numerical simulations of Faraday waves at the liquid - vapor interface of fluids (typically CO2 and H2) near its critical point when submitted to vibration in a weightlessness environment. It is known that in such a system striation is formed under the action of vibrations. The boundary between the liquid and gas phases is located perpendicular to the direction of vibrations, and a streaky structure in the form of periodic stripes (striations) is formed in the cavity. It is shown that under vibrations of sufficient intensity an instability develops on the striation interface perpendicular to the direction of vibrations, leading to Faraday waves. A theoretical and numerical study of this instability is carried out, the critical parameters of the appearance of Faraday waves are determined taking into account the interaction of waves on adjacent striations. Dispersion relations for Faraday waves are obtained numerically. It is shown that in the vicinity of the critical point there is a significant deviation of the dispersion relation from the classical theoretical dependence.

All availability conditions of roads inserted to attribute table of ArcGIS 10.2 and analyzed geospatial operations. On maps, created by not road organizations, information about roads is presented in a standard form, which leads to the lack of modern information on the condition of roads.
Brazilian Journal of Chemical Engineering ETHANOL DEHYDRATION IN PACKED DISTILLATION COLUMN USING GLYCEROL AS ENTRAINER : EXPERIMENTS AND HETP EVALUATION

The ethanol-water separation is very important because ethanol is widely applied in the chemical industry and its use as a fuel can reduce the pollution emitted to the air. However, anhydrous ethanol production using conventional distillation is impossible, at atmospheric pressure, due to the presence of an azeotrope. In the present work, experimental tests were carried out in order to evaluate the use of glycerol as an entrainer, in substitution of ethylene glycol in an extractive distillation. The use of glycerol is motivated by the biodiesel production units, due to the fact that it is the main byproduct and a new market is necessary to consume its overproduction. The experiments were carried out in a distillation column packed with Raschig rings, varying the glycerol/feed (ethanol and water) ratio, S/F, from 0.5 to 0.9. The samples were analyzed using a digital densimeter. The results showed that glycerol was effective to promote ethanol dehydration and the presence of an azeotrope was not observed using a solvent to feed ratio (S/F) equal to 0.9. Some empirical correlations were investigated to evaluate the HETP (Height Equivalent to a Theoretical Plate), and the results provided a useful tool for designing a packed bed column for ethanol-water separation.
Effects of WhatsApp Based Online Learning to Students' Satisfaction during COVID-19 Mitigation in Rural Area of Indonesia

Covid-19 pandemic has a significant impact on learning practices in various countries. The Government of Indonesia conducts Covid-19 Mitigation in various sectors, including education. MOEC (Ministry of Education and Culture) issued regulations to organize knowledge using online learning at all levels of schools in all regions. Elementary schools in rural areas face obstacles in implementing online learning according to government regulations during the pandemic. Teachers use a variety of applications when carrying out online learning. Teachers use social media applications the most in education during this rapid change situation. One of the social media used during this mitigation is WhatsApp. This study aims to describe the response of learner’s satisfaction in Nusa Tenggara Timur, Indonesia, during online learning with this media. This research is a quantitative descriptive study using the COLLES questionnaire. This questionnaire was created using Google Form and distributed through WhatsApp Group to students. The sampling technique used was the purposive sampling of 123 students who joined online lectures using this media. The results of this study show that students are generally satisfied with online learning. Some aspects that need to be improved are at the level of appreciation, lecturer feedback during lectures. These results provide optimism for online learning as a new learning process in the modern era after Covid-19 mitigation ends.

Chromaticity manipulation of indoor photovoltaic cells

Organic photovoltaic cells are appealing as indoor illumination harvesters to drive off-grid electronics in the Internet of things. However, a desirable output power usually requires expansive and dark active layers to absorb sufficient incident photons. The deployment of such large-scale dark objects is detrimental to the elaborately designed indoor lighting environment and affects human visual perceptions. Here, we propose a free-contact strategy to adjust the chromaticity of the transmitted indoor light by applying one-dimensional photonic crystals. Combining photonic crystals with various transmittances outside the photovoltaic cells, the spectral power distribution of the transmitted light can be precisely manipulated to realize a broad and consecutive color modulation covering the region from blue to orange. For certain photonic crystals, the chromaticity of propagated light can be recovered close to the light source. This work presents a solution to relieve light-disturbing in the application of organic photovoltaic cells under indoor illuminations.
The militarization of responses to COVID-19 in Democratic Latin America

Abstract Latin America has been severely affected by the COVID-19 pandemic, prompting its governments to take action. In this context, countries within Latin America have used their armed forces for an array of tasks to serve citizens. But how militarized is the response to COVID-19 in Latin America? This paper proposes a typology of tasks provided by the armed forces as a response to COVID-19. The descriptive findings allow us to map these tasks, attributing scores to the fourteen Latin American democracies. We also show evidence for the potential consequences of some tasks. Policing the streets to enforce stay-at-home orders may lead to the military committing human rights violations, assuming eminently civilian posts to manage the public health crisis can result in long term implications for the civil-military balance that are detrimental to the democratic control over the military.
