Authors: Comeras Angel B. , Raposo Javier F. , De Luxan Margarita
Published: October 2017

Las personas con discapacidad intelectual,  grado de discapacidad leve y mayores de edad, utilizan expresiones artísticas como vehículo de expresión, comunicación y adaptación cultural. Los significativos cambios producidos hacia concepciones de la discapacidad intelectual más dinámicas, basadas en mayores interacciones, de la discapacidad intelectual, han conducido hacia la promoción de actividades artísticas y sensoriales con positivos resultados perceptivos y de comunicación. Se han realizado prácticas durante cinco años, entre estudiantes de Arquitectura, estudiantes de otras áreas de conocimiento (Farmacia, Enfermería, Fisioterapia y Comunicación) y personas con discapacidad intelectual, sobre aspectos cognitivos, sensoriales y sociales, donde han sido contrastadas y asumidas diversas  percepciones artísticas, para expresar algunas dificultades en el uso de los entornos construidos. La implementación, de algunas percepciones artísticas asumidas, en estrategias cognitivas de generación arquitectónica es beneficiosa para el uso de edificios destinados a personas con discapacidad intelectual. Se aportan y describen dos ejemplos reales de edificios donde han sido aplicadas, en sus inicios proyectuales, plasmaciones artísticas conocidas que han producido un aumento en su comprensión y reconocimiento espacial, transcurrido un tiempo mayor de diez años como usuarios.

Authors: H. Belver Manuel , Ullán Ana Mª
Published: October 2017

The goal of this study was to determine whether experts attribute a series of images created by people with dementia who were participating in a program of contemporary art education to artists or to people without prior artistic experience. In this way, we sought to obtain an indicator of the artistic quality of the images produced by people with dementia. Participants were 122 specialists in art to whom were presented 30 images, 15 works by professional artists and 15 created by people with dementia. For each of the 15 images created by the people with dementia, we calculated the proportion of experts who attributed the image to a professional artist. The results indicated that, in a significant number of cases, which varied according to the images, the experts attributed the images to professional artists. The judgment of the experts reinforcing the idea of the creative potential of people with dementia.

Authors: Nyaruwata Shepherd , Runyowa Douglas
Published: October 2017

The tourism industry in Zimbabwe has experienced fluctuating trends in its growth since the dawn of the new millennium. The Ministry of Tourism and Hospitality Industry undertook a visitor exit survey in 2015/2016 period. The purpose of the study was to gather visitors’ views on Zimbabwe as a tourist destination in order to guide policy formulation on the sector. One of the objectives of the survey was to assess the visitor perceptions of Zimbabwe as a competitive tourist destination. Questionnaires were administered to departing visitors at the country’s three international airports and seven border posts during the period July 2015 until June 2016. The results of the survey indicated that 77% of visitors use road transport to enter into the country. The survey also showed that 18% of visitors to the country travelled by air. It is recommended that that the government accelerates the implementation of the open skies policy so as to attract more direct international airlines to fly into the country. It is also recommended that the government undertakes massive improvement of the road infrastructure in the country so as to encourage the geographical distribution of tourists within the country. It is finally recommended that the private sector and the national tourist organization, Zimbabwe Tourist Authority (ZTA) engage international tour operators and persuade them to develop and promote fly-drive tour packages to the country.

Authors: Hero Laura-Maija , Lindfors Eila , Taatila Vesa
Published: October 2017

Learning for innovation is a central element in European policymaking in developing higher education. Students often learn in project settings together with work organizations developing new solutions, products and services. These authentic creative, social and collaborative settings offer an attractive learning environment. The aim of this study was to determine the factors involved in individual innovation competence to be able to design, tutor and assess the pedagogical processes where authentic open-ended tasks are being solved transforming novel ideas into usable products or services. After defining the extraction criteria using a limited sample of articles, a bias-assessed systematic review was conducted of empirical research articles published in 2006–2015. Twenty-eight journal articles were ultimately included in the review. Despite the volume of academic literature in this field, comparatively few studies providing findings addressing the review objectives could be found. There was, however a reasonable weight of research evidence to support the result. The findings suggest that personal characteristics, such as flexibility, achievement orientation, motivation and engagement, self-esteem and self-management, future orientation, creative thinking skills, social skills, project management skills, and content knowledge and making skills can be needed in collaborative innovation process. These findings have implications for pedagogical innovation processes and for competency-based assessment.

Authors: Tanan Tamara Torres , Nascimento Marilza Neves do , Leite Romeu Da Silva , Guimarães David Santana
Published: October 2017

The aim of this study was to compare different protocols for extraction and quantification of photosynthetic pigments, considering different solvents, extraction time and temperature, to determine the best methodology for Physalis angulata L. leaves. The efficiency of immersion of leaf discs in 95% ethanol, 80% acetone and dimethyl sulfoxide (DMSO) was evaluated for 24, 48 and 72 hours. The effect of temperature on extraction with DMSO was also evaluated, with the samples incubated at room temperature and in a water bath at 65 °C. These protocols were compared with the classical methods of plant tissue maceration in 80% acetone followed by filtration, which proved to be the most efficient for Physalis angulata plants and indicated for use in the laboratory. The use of high temperatures (65 °C) is not necessary for the chlorophyll extraction process with DMSO, the room temperature is most efficient in the extraction of carotenoids. Considering the total chlorophyll content, the leaf discs immersion technique in a solvent is acceptable, with 95% ethanol and 24 hours incubation and the most economically viable alternative.

Published: October 2017

Apis mellifera bees that forage in agricultural fields may be exposed to pesticides through many routes. One of them is the collection of pollen contaminated with insecticides. In this study, we evaluate the mortality of adult honeybees exposed to pollen from cotton plants whose seeds were treated with insecticides thiamethoxam, clothianidin, imidacloprid and fipronil, and the pollen collection capacity of adult honeybees in cotton fields. Bee mortality based on linear regression analysis showed significant differences, but no differences were noted among treatments. According to the contrast analysis of the mean groups of insecticides against the mean of the control group, no significant differences were found, indicating a natural mortality for all treatments including the control. Quantitative analysis of the pollen revealed the presence of only cotton pollen grains on bees, indicating floral fidelity of Africanized honeybees. Pearson’s correlation coefficient was positive, but statistically insignificant, for increase in pollen collection with time.

Published: October 2017

The reuse of solid and liquid wastes has become a viable practice for the sustainability of agricultural production, because it meets the nutritional needs of crops and also allows the use of nutrients present in these residues. The objective of this work was to analyze the nutritional value of Tifton 85 irrigated with treated domestic wastewater and fertilized with nitrogen doses from poultry bed in four successive cuts, with frequency of 35 days. The experiment was set up in a protected environment, arranged in a completely randomized experimental design, in a 5 × 2 factorial scheme, with four replications. Five doses of nitrogen were tested through organic fertilization from avian beds (0, 15, 30, 45 and 60 kg N ha-1) and two irrigation water qualities (treated domestic well and artesian well). After the cuts the material was dried and sent to the laboratory to determine the following parameters: crude protein (CP), neutral detergent fiber (NDF) and Tifton 85 acid detergent fiber (ADF). The highest values of crude protein were obtained using the domestic wastewater treated in the irrigation, as well as using the higher doses of nitrogen from poultry litter. Just as the NDF and ADF contents presented the best values when treated domestic wastewater and the highest nitrogen doses. Indicating that irrigation with wastewater and the use of organic fertilizer may substitute for conventional manures by promoting satisfactory levels of concentrations for fodder.

Published: October 2017

Three on-farm research-managed trials were conducted in Settat province, Chaouia, semi-arid Morocco, from 2012-13 to 2014-15, to investigate the dynamics of germinable soil seedbank, weed density, and community composition of weeds in 3 crop rotations: continuous durum wheat, barley + pea/durum wheat/durum wheat, and canola/durum wheat/durum wheat. Initial germinable weed seedbank density estimated in September 2012, before no-till planting in November 2012 was 1890 seeds m-2. After two growing seasons, seedbank reductions were 23% in continuous durum wheat, 68% in canola/durum wheat/durum wheat, and 72% in barley + pea/durum wheat/durum wheat. In continuous durum wheat, weed densities before no-till planting were 273, 46, and 59 plants m-2 in November 2012, December 2013, and November 2014, respectively. In herbicide-free barley + pea/durum wheat/durum wheat, weed densities before no-till planting durum wheat were 128 and 42 plants m-2 in December 2013 and November 2014, respectively. In canola/durum wheat/durum wheat, weed densities before no-till planting wheat were only 20 and 25 plants m-2 in December 2013 and November 2014, respectively. This study demonstrated the combined merits of pre-plant glyphosate, herbicide use in wheat, herbicide-free barley + pea haying, and durum wheat rotation with either canola or barley + pea to manage weeds in no-till systems in semi-arid Morocco.

Published: October 2017

Partial replacement of potassium by sodium may be an alternative to reduce the cost of pasture fertilization and reduce the dependence on imported potassium sources. The objective of this study was to evaluate different sources and doses of calcium as enhancers of sodium effect on the partial replacement of potassium by sodium. Here, Mombaça grass (Megathyrsus maximus) was grown on low fertility soil. The experiment was conducted in a factorial (3 × 5) based on a completely randomized design with 4 replications as follow: three sources of Ca2+ (dolomitic limestone, agricultural gypsum and calcium chloride), five doses of Ca2+ (0, 10, 20, 30 and 40 mg dm-3) and two additional treatments (fertilization with 100% of K+ without application of Ca2+ and one control without any fertilization). Potassium was partially replaced (25%) by Na+ prior to Ca2+ additions. Plant height, growth rate, dry weight, Na+, K+, K+/Na+ and shoot proline contents were evaluated as well as Na+ levels and the electrical conductivity of the soil. The results show that the addition of Ca2+ provided better plant development when K+ was partially replaced by Na+ and that the supply of Ca2+ reduced the absorption of sodium by plants. The partial replacement of K+ by Na+ did not increase soil salinity or caused stress to the plants.

Published: October 2017

Soil borne archaea in agricultural systems is crucial for cycling of nutrient such as Nitrogen, Carbon and Sulphur. The objective of the study was to assess the effect of different tillage systems on functional archaea diversity in a 15 years cereal-legume rotation field using Illumina sequencing platform for archaea 16S rRNA gene. The treatments in the study included conventional tillage with stubble removed (T), no-till with stubble removed (NT), conventional tillage with stubble incorporated (TS) and no-till with stubble retained (NTS). The results showed that the dominant soil archaea phyla was Crenarchaeota (> 96%), followed by Euryarchaeota with a lower abundance of < 3% and then Parvarchaeota and other bacteria phyla made up < 1% across the treatments and depths. The treatment means were ranked as NT > NTS > TS > T for 16S rRNA number of OTUs, Shannon and Simpson indices calculated for the 0-10cm soil depth. Analysis of factor effect revealed that tillage but not stubble retention or their interaction significantly influenced (P < 0.01 and P < 0.05) 16S rRNA diversity. Non metric Multidimensional Scaling (NMDS) analysis clearly grouped the microbial communities according to depths. Linear Discriminant Analysis Effect Size (LEfSe) identified Crenarchaeota and Thaumarchaeota (to genus level) as significantly enriched clades in 0-10 cm depth of T while Euryarchaeota and Thermoplasmata were significantly enriched in TS. The conservational tillage systems (NT and NTS) promoted even distribution of archaea diversity while conventional tillage systems (T and TS) enriched the archaea communities identified in the study.

This study aimed to evaluate the residual effect of phosphorus sources and application techniques in the intercropping of forages during off-season crops. The experimental design was randomized blocks in a 4 × 2 + 1 factorial, being four sources of phosphorus [Bayóvar Reactive Phosphate (BRP), Monoammonium Phosphate (MAP), Simple Superphosphate (SS) and Triple Superphosphate (TS)], two application techniques (broadcasting and on rows) and an additional without phosphorus. The experiment was conducted during the off-season crop. The residual effect of phosphorus fertilization increased the growth and the production of biomass of forage sorghum regarding broadcast SS and TS sources. The lowest P contents in the tissue of plants fertilized with SS and TS may be attributed to the diluting effect, as it achieved the highest production of biomass. The application of TS favored a greater dry matter production in Brachiaria brizantha cv. Piatã. At the depth 0.00-0.05 m, there was a higher P content with the application of BRP. However, the production of biomass was low, a factor that may be related to an overestimation of P bound to Ca by the Mehlich-1 extractor. Under cultivation conditions, broadcast SS and TS had a higher residual effect.

Rotas marítimas no Ártico / Arctic sea routes
Authors: Júnior Enoil De Souza , Da Rosa Kátia Kellem , Simões Jefferson Cardia
Published: October 2017

Desde o período das Grandes Navegações, mais precisamente nos séculos XV e XVI, procura-se uma maneira mais rápida de ligar a Europa, Ásia e América. Nessa procura muitos exploradores se aventuraram no Ártico, porém naquela época, as condições climáticas eram diferentes das atuais, sendo que o gelo marinho cobria quase toda extensão do Oceano Ártico mesmo no verão.  Assim, as rotas marítimas árticas não puderam ser exploradas por muito tempo. Entretanto, com o atual aquecimento no Ártico e a consequente retração do gelo marinho, o que era um sonho passa a ser realidade: as rotas que outrora foram abandonadas por serem de difícil acesso, passam a ligar o mundo de maneira mais rápida e barata. Neste artigo examina a procura por essas rotas em artigos científicos e em livros que relatam registros históricos e qual é a expectativa para o século XXI.

Palavras–chave: Rota Nordeste, Rota Noroeste, Ártico.

Abstract

Since the Great Navigations period, 15th and 16th centuries, there has been a search for faster sea-lanes to connect Europe, Asia and America. In this search many explorers ventured in the Arctic, however, at that time the climatic conditions were different from the current ones, sea ice covered almost the entire length of the Arctic Ocean even in high summer, so for a long time the Arctic sea routes could not be explored. Presently, the Arctic warming and the consequent decline of sea ice cover area, make such routes a reality and could potentially connect the world more quickly and cheaply. This paper examines the search for these routes in papers and books that reports historical events and what could be expected for the 21th century.

Este trabalho tem como objetivo caracterizar os aspectos fitossociológicos de cinco fragmentos florestais inseridos no perímetro das zonas norte e leste da cidade de Manaus-AM. Foram abertas cinco parcelas de 20x20 m entre ambientes de vertentes e baixio. Considerou-se para a área de amostragem DAP acima de 10 cm com base em Durigan (2003). Os resultados obtidos na análise fitossociológica indicam que as parcelas apesar de estarem isoladas, apresentaram semelhanças quanto a sua fisionomia floristica consistindo em indivíduos de espécies arbórea com resquício de vegetação primária. Os fragmentos de modo geral caracterizam-se como sendo uma floresta de vegetação secundária, em estágio médio de regeneração, contendo árvores de altura predominante entre 5 a 32 metros. Os índices de diversidade indicam que apenas duas dentre as cinco obtiveram valor acima de 2,0. Ademais, o valor foi inferior e considerado baixo quando comparados com outros estudos de fragmento no Amazonas.

Palavras–chave: Fragmentos Florestais, Vegetação, Fitossociologia

Abstract

This work aims to characterize the phytosociology aspects of five forest fragments inserted in the perimeter of the north and east of the Manaus-AM city. Five 20 x 20 m plots were opened between slope and shallow environments. The DAP sampling area above 10 cm based on Durigan (2003) was considered for the sampling area. The results obtained in the phytosociological analysis indicate that the plots, although isolated, presented similarities as to their floristic physiognomy consisting of individuals of arboreal species with remnants of primary vegetation. The fragments are generally characterized as being a forest of secondary vegetation, in the middle stage of regeneration, containing trees of predominant height between 5 and 32 meters. Diversity indices indicate that only two of the five had a value above 2,0. In addition, the value was lower and considered low when compared with other fragment studies in Amazonas.

Relationship between childhood (un)predictability and life milestones in young Brazilians
Authors: Luquine Júnior Cézar Donizetti , Howat-Rodrigues Anna Beatriz Carnielli , Izar Patrícia
Published: October 2017

The present study sought to investigate whether perceived family unpredictability affects the development of life history strategies in both the reproductive and somatic domains by evaluating the ages at which life milestones occurred. In this study 211 young Brazilians answered a 10-item instrument that contained future milestones, the Family Unpredictability in Childhood, and a sociodemographic questionnaire. Not all participants had already achieved the milestones. Earlier ages of giving birth to the first child, marrying, starting a family, and at first formal employment were correlated with greater unpredictability scores. Significant correlations were found more frequently for the participants who had already met the milestones. Data support the importance of the childhood environment for later development. Results suggest that data obtained based on the ages at which milestones occurred and ages at which milestones are expected to occur may present important differences with regard to the influence of environmental factors.
Restricted and Repetitive Behaviour in Persons with Autism (Ages 0-18): An Integrative Review of Treatment Related to Occupational Therapy
Authors: Patriquin Melissa , MacKenzie Diane , Versnel Joan
Published: October 2017

Objective: To identify evidence-based behavioural interventions used to decrease restricted and repetitive behaviour (RRB) in children with autism (ages 0-18); to understand the application of these strategies within the PEO (Person, Environment, Occupation) Model of Occupational Performance and the role of the occupational therapist in addressing this limitation.
Background: RRB is a core feature of autism that often impedes functional behaviour. Decreasing RRB to enable functional behaviours is central to the occupational therapist’s role with this population. Many interventions identified as effective for this impairment are based on the principles of applied behaviour analysis (ABA).
Method: An integrative review of the literature was completed to identify interventions targeting RRBs. Those found to be effective are described within an ABA framework and within the PEO Model of Occupational Performance. 
Results: This review identified twenty-eight effective interventions used to treat RRBs in autism relevant to the field of occupational therapy. Categorization of interventions using an ABA framework and the PEO Model allowed comparison between approaches and application to occupational therapy practice.
Conclusion: A functional behaviour approach (FBA) used in combination with the PEO model will enable greater understanding of RRBs and provide a more comprehensive approach to the treatment of RRBs in children with autism.
Pour une éthique de la reconnaissance
Authors: Grenier Josée , Bourgeault Guy
Published: October 2017

L’aspiration à la reconnaissance de leur individualité ressort de témoignages de personnes âgées reçus lors d’une recherche récente. Elle n’est guère satisfaite par des pratiques institutionnelles de plus en plus standardisées liées aux exigences de gestion institutionnelle et renforcée par celles de la Nouvelle gestion publique (NGP). L’éthique professionnelle du travail social se vit dès lors dans la tension entre la soumission aux règles et la délibération, celle-ci exigeant la prise en compte à la fois de la complexité des situations et des pratiques, et, d’une part, de l’aspiration des personnes auxquelles les services sont dispensés, et d’autre part, d’une reconnaissance d’elles-mêmes dans leur singularité et l’unicité de chaque expérience de vieillir. Le travail social, pratique prudentielle (Champy, 2009, 2011, 2012) requérant l’exercice de la sagesse pratique dans la délibération, appelle, pour l’intervention auprès des personnes âgées notamment, une éthique de la reconnaissance dans ses volets personnel ou interpersonnel et social, voire proprement politique.
La caractérisation des communautés locales
Authors: Simard1 Paule , Benazera Clara , Boyer Ginette , Charland Martin
Published: October 2017

Cet article analyse une démarche de caractérisation des communautés locales visant à « mieux connaître pour mieux agir » avec ces communautés. Issu de la santé publique, le dispositif original (Boisvert, 2007) propose une série d’opérations s’appuyant sur l’idée qu’une bonne connaissance des forces, des faiblesses et du potentiel de la communauté constitue un facteur de succès de son développement. L’étude dont il est question ici cherchait à montrer si le dispositif contribue au développement des communautés. Le cadre conceptuel était structuré autour des étapes de la démarche et de principes fondateurs du développement des communautés (intersectorialité,empowerment, participation citoyenne). L’évaluation a été menée dans trois régions du Québec, puis doublée d’une analyse transversale.

An Empirical Model of Titan's Magnetic Environment During the Cassini Era: Evidence for Seasonal Variability
Authors: Kabanovic Slawa , Simon Sven , Neubauer Fritz M. , Meeks Zachary
Published: October 2017

Based on the magnetic field data collected during the Cassini era, we construct an empirical model of the ambient magnetospheric field conditions along the orbit of Saturn's largest moon Titan. Observations from Cassini's close Titan flybys as well as 191 nontargeted crossings of Titan's orbit are taken into account. For each of these events we apply the classification technique of Simon et al. (2010b) to categorize the ambient magnetospheric field as current sheet, lobe‐like, magnetosheath, or an admixture of these regimes. Independent of Saturnian season, Titan's magnetic environment around noon Saturn local time is dominated by the perturbed fields of Saturn's broad magnetodisk current sheet. Only observations from the nightside magnetosphere reveal a slow but steady change of the background field from southern lobe‐type to northern lobe‐type on a timescale of several years. This behavior is consistent with a continuous change in the curvature of the bowl‐shaped magnetodisk current sheet over the course of the Saturnian year. We determine the occurrence rate of each magnetic environment category along Titan's orbit as a function of Saturnian season and local time.

Secondary electrons are continuously generated via photoemission from sunlit spacecraft and instrument surfaces. These particles can subsequently contaminate low‐energy channels of electron sensors. Spacecraft photoelectrons are measured at energies below that of a positive spacecraft potential and can be removed at the expense of energy resolution. However, fluxes of photoelectrons generated inside electron instruments are independent of spacecraft potential and must be fully characterized in order to correct electron data. Here we present observations of spacecraft and instrument photoelectron populations measured with the Dual Electron Spectrometers (DES) on NASA's Magnetospheric Multiscale (MMS) mission. We leverage observations from Earth's nightside plasma sheet taken during MMS commissioning and develop an empirical model of instrument photoelectrons. This model is used with DES velocity distribution functions to correct plasma moments and has been made publicly available on the MMS science data center for use by the scientific community.

Using data from Time History of Events and Macroscale Interactions during Substorms (THEMIS), a statistical study was performed to determine whether a dawn‐dusk asymmetry exists in the occurrence rates of the Kelvin‐Helmholtz instability during Parker‐Spiral (PS) and Ortho‐Parker‐Spiral (OPS) orientations of the interplanetary magnetic field (IMF). It is determined from the data that there is a strong preference toward the dawnside during PS orientation, and although a preference to the duskside during OPS is suggested, this requires further study for an unambiguous confirmation. The uncertainty in the OPS result is due to a low number of events, which satisfied our selection criteria. Because IMF is statistically in PS orientation, the Kelvin‐Helmholtz instability (KHI) preference for the dawn flank during this orientation may help explain the origin of the plasma sheet asymmetry of cold component ions because it has been shown that KHI can drive kinetic‐scale wave activity capable of ion heating.

We analyze two ion scale dipolarization fronts associated with field‐aligned currents detected by the Magnetospheric Multiscale mission during a large substorm on 10 August 2016. The first event corresponds to a fast dawnward flow with an antiparallel current and could be generated by the wake of a previous fast earthward flow. It is associated with intense lower hybrid drift waves detected at the front and propagating dawnward with a perpendicular phase speed close to the electric drift and the ion thermal velocity. The second event corresponds to a flow reversal: from southwward/dawnward to northward/duskward associated with a parallel current consistent with a brief expansion of the plasma sheet before the front crossing and with a smaller lower hybrid drift wave activity. Electromagnetic electron phase‐space holes are detected near these low‐frequency drift waves during both events. The drift waves could accelerate electrons parallel to the magnetic field and produce the parallel electron drift needed to generate the electron holes. Yet we cannot rule out the possibility that the drift waves are produced by the antiparallel current associated with the fast flows, leaving the source for the electron holes unexplained.

The enhanced ratio of deuterium to hydrogen on Mars has been widely interpreted as indicating the loss of a large column of water into space, and the hydrogen content of the upper atmosphere is now known to be highly variable. The variation in the properties of both deuterium and hydrogen in the upper atmosphere of Mars is indicative of the dynamical processes that produce these species and propagate them to altitudes where they can escape the planet. Understanding the seasonal variability of D is key to understanding the variability of the escape rate of water from Mars. Data from a 15 month observing campaign, made by the Mars Atmosphere and Volatile Evolution Imaging Ultraviolet Spectrograph high‐resolution echelle channel, are used to determine the brightness of deuterium as observed at the limb of Mars. The D emission is highly variable, with a peak in brightness just after southern summer solstice. The trends of D brightness are examined against extrinsic as well as intrinsic sources. It is found that the fluctuations in deuterium brightness in the upper atmosphere of Mars (up to 400 km), corrected for periodic solar variations, vary on timescales that are similar to those of water vapor fluctuations lower in the atmosphere (20–80 km). The observed variability in deuterium may be attributed to seasonal factors such as regional dust storm activity and subsequent circulation lower in the atmosphere.
Quantitative Assessment on Multiple Timescale Features and Dynamics of Sea Surface Suspended Sediment Concentration Using Remote Sensing Data

Wind‐waves, tidal currents, and some other dynamic factors dominate the suspended sediment concentration (SSC) variations in shallow seas and it is difficult to quantitatively evaluate the effects of individual dynamic factors on SSC modulation. This work used the long‐term Moderate Resolution Imaging Spectroradiometer (MODIS) and the high temporal‐resolution Geostationary Ocean Color Imager (GOCI) remote sensing data to quantify the sea surface SSC variations on multiple timescales (intratidal, spring‐neap, seasonal, and long‐term timescales) in the Bohai Sea, and further quantitatively evaluated the effects of corresponding dynamic factors on the SSC modulation. The results indicated that the monsoon associated wind‐waves and stratification played the most important role in modulating SSC, with seasonal SSC variation of 8.1 mg/L in the Bohai Sea. The intratidal current variations played the secondary important role, causing SSC variation of 5.8 mg/L. The spring‐neap tidal current variations led to SSC variation of 3.1 mg/L in the Bohai Sea. In the long run (2003–2014), the SSC of the Bohai Sea decreased slightly with SSC variation of 2.8 mg/L (decline rate: 0.23 mg/L/year), which may be caused by the weakening wind, decreasing sediment load from the Yellow River or the massive reclamation in recent decades. Probably due to the topography, sea bed sediment grain size and river plume, SSC variations in the southern Bohai Sea were more pronounced than those in the northern Bohai Sea.
Impacts of Horizontal Propagation of Orographic Gravity Waves on the Wave Drag in the Stratosphere and Lower Mesosphere

Published: October 2017

The impact of horizontal propagation of mountain waves on the orographic gravity wave drag (OGWD) in the stratosphere and lower mesosphere of the Northern Hemisphere is evaluated for the first time. Using a fine‐resolution (1 arc min) terrain and 2.5°×2.5° European Centre for Medium‐Range Weather Forecasts ERA‐Interim reanalysis data during 2011–2016, two sets of OGWD are calculated offline according to a traditional parameterization scheme (without horizontal propagation) and a newly proposed scheme (with horizontal propagation). In both cases, the zonal mean OGWDs show similar spatial patterns and undergo a notable seasonal variation. In winter, the OGWD is mainly distributed in the upper stratosphere and lower mesosphere of middle to high latitudes, whereas the summertime OGWD is confined in the lower stratosphere. Comparison between the two sets of OGWD reveal that the horizontal propagation of mountain waves tends to decrease (increase) the OGWD in the lower stratosphere (middle to upper stratosphere and lower mesosphere). Consequently, including the horizontal propagation of mountain waves in the parameterization of OGWD can reduce the excessive OGWD in the lower stratosphere and strengthen the insufficient gravity wave forcing in the mesosphere, which are the known problems of traditional OGWD schemes. The impact of horizontal propagation is more prominent in winter than in summer, with the OGWD in western Tibetan Plateau, Rocky Mountains, and Greenland notably affected.

Due to its simplicity, versatility, and high efficiency, the clustered regularly interspaced short palindromic repeat (CRISPR)/Cas9 technology has emerged as one of the most promising approaches for treatment of a variety of genetic diseases, including human cancers. However, further translation of CRISPR/Cas9 for cancer gene therapy requires development of safe approaches for efficient, highly specific delivery of both Cas9 and single guide RNA to tumors. Here, novel core–shell nanostructure, liposome‐templated hydrogel nanoparticles (LHNPs) that are optimized for efficient codelivery of Cas9 protein and nucleic acids is reported. It is demonstrated that, when coupled with the minicircle DNA technology, LHNPs deliver CRISPR/Cas9 with efficiency greater than commercial agent Lipofectamine 2000 in cell culture and can be engineered for targeted inhibition of genes in tumors, including tumors the brain. When CRISPR/Cas9 targeting a model therapeutic gene, polo‐like kinase 1 (PLK1), is delivered, LHNPs effectively inhibit tumor growth and improve tumor‐bearing mouse survival. The results suggest LHNPs as versatile CRISPR/Cas9‐delivery tool that can be adapted for experimentally studying the biology of cancer as well as for clinically translating cancer gene therapy.

Wireless functionality is essential for the implementation of wearable systems, but its adaptation in stretchable electronic systems has had limited success. In this paper, the electromagnetic properties of stretchable serpentine mesh‐based systems is studied, and this general strategy is used to produce high‐performance stretchable microwave systems. Stretchable mechanics are enabled by converting solid metallic sections in conventional systems to subwavelength‐scale serpentine meshes, followed by bonding to an elastomeric substrate. Compared to prior implementations of serpentine meshes in microwave systems, this conversion process is extended to arbitrary planar layouts, including those containing curvilinear shapes. A detailed theoretical analysis is also performed and a natural tradeoff is quantified between the stretching mechanics and microwave performance of these systems. To explore the translation of these concepts from theory to experiment, two types of stretchable microwave devices are fabricated and characterized: a stretchable far‐field dipole antenna for communications and a stretchable midfield phased surface for the wireless powering of biomedical implanted devices.
