Authors: Горбачевская Евгения
Published: June 2020

. Natural resources conservation and sustainable living have become important issues worldwide. Among natural resources, energy is one of the important prerequisites for sustainable development. Therefore, in order to meet the high demand for energy, it is necessary to bring its sustainable consumption to the forefront of the development strategy of construction industry. The construction sector development in the Russian Federation is largely determined by national projects whose main goal is to provide citizens with comfortable and affordable housing. The national program announced by the government can be successfully implemented by the means of energy-efficient technologies usage, in particular, while building low-rise housing.

This study aims to determine the effect of the use of guided inquiry methods on students' science learning results at SDI Wae Ratun. This school is one of the schools in underdeveloped regions. This type of research is a quasi-experimental study with posttest only control group design research. The subject of the study was the fifth-grade students with sampling techniques using random class techniques. The sample chosen in this study was class V B as the experimental class and class V A as the control class. The instrument used is a test in the form of multiple-choice questions. Data analysis uses descriptive and inferential statistics. The results of data analysis obtained the calculation of tcount = 4.940 and ttable = 2.026 at a significant level and degrees of freedom = 35. Thus, there is a substantial influence on the use of guided inquiry learning models on student science learning results at SDI Wae Ratun.
SEMI-STRUCTURED DESIGN AND PROBLEM-BASED EXPERIENTIAL LEARNING IN A FIRST-YEAR BIOMEDICAL ENGINEERING LABORATORY COURSE
Authors: Lam Gabrielle , Gill Navjot , Ghaemi Roza
Published: June 2020

A first-year biomedical engineering laboratory course was created using a problem-based approach, introducing students to the interplay of engineering design and biology in biomedical engineering. Open-ended problems were central to each laboratory module, and were designed to enhance students’ development of high-order learning skills. Although the value of problem-based learning in engineering laboratory courses has been recognized, its implementation in the first-year engineering program presents unique challenges for students who are unfamiliar with the unstructured approach and who are in their early stages of developing discipline-specific knowledge. Immediate feedback scaffolding strategies, including interactive pre-laboratory assessments and team-based quizzes, were implemented in the second iteration of the course to support students’ achievement of learning outcomes, and to improve their perception of their learning experience in a problem-based laboratory. According to preliminary survey results, students attributed the value of problem-based laboratory activities to the acquisition of technical skills, engineering design skills, as well as the development of self-directed ability, and a growth mindset. Results from the second iteration of the course also revealed that students perceived the interactive pre-laboratory assessments and team-based quizzes to be highly valuable. Taken together, our study thus far has underlined the importance of immediate feedback as an effective scaffolding strategy for supporting semi-structured experiential learning in a first-year engineering laboratory course.
MACRO-COGNITIVE ANALYSIS OF DESIGN SKILLS FOR SUPPORTING ENGINEERING DESIGN EDUCATION
Authors: Li S. , Gress G.
Published: June 2020

Macro-cognition is a field of study that investigates how domain experts (e.g., firefighters and weather forecasters) make decisions and judgements for their work.  This paper has adapted two models from macro-cognition to better understand design activities. The first one is the Data / Frame model, and it tells how a person’s frame can influence the selection of information in the design process.  The second one is the recognition-primed decision (RPD) model, which shows how a design idea emerges with a person’s recognition and mental simulation.  Based on these models, we further suggest three intervention strategies (i.e., challenge, relate and demonstrate) to support the processes of sensemaking, recognition and mental simulation.  We also suggest two evaluation aspects, i.e., relevance and fluency, to assess design activities.
THE “ENGINEERS HAVE FEELINGS” PROJECT: INTEGRATING MENTAL WELLNESS AND LIFELONG LEARNING SKILLS IN FIRST-YEAR UNDERGRADUATE ENGINEERING COURSES
Authors: Paul Robyn , Dedemus Destiny , Boyce Melissa , Johnston Kim
Published: June 2020

To address an identified need for programming that helps Engineering students to develop skills in coping, resilience, and lifelong learning, we designed, implemented, and reflected on the effectiveness of a curricular intervention on Engineering students’ mental wellbeing, academic engagement and achievement, and perceptions of support. This intervention has implications for the development of a model of the curricular components necessary to benefit undergraduate students’ academic engagement, success, and perceptions of student support. It may also be used to inform curriculum development across many university programs.
ENGINEERING TEAM DYNAMICS: CONNECTING FRIENDSHIP NETWORKS AND ACADEMIC TRAJECTORIES
Authors: Cyr Emily N. , Donald John , Bergsieker Hilary B.
Published: June 2020

Women are under-represented in STEM careers, especially engineering, as women are both less likely to enter engineering majors [1] and more likely to exit prematurely [2].  Women who leave engineering before achieving a career are then often underemployed [3]. We used an integrated research strategy to study how undergraduate classroom experiences might impact these gendered career trajectories, simultaneously modelling intrapersonal cognitions and interpersonal dynamics of students. Specifically, we studied cross-disciplinary engineering undergraduate teams over their first term in university. Importantly, this course was designed to have significant team interaction, and teams were assigned with the intention of reducing gendered barriers to participation and achievement. Our results revealed widespread gender equity (and the few observed inequities tending to shrink over the term). Further, we demonstrate specific intrapersonal and interpersonal factors that are linked to stronger academic trajectories (here operationalized as better final grades). Potential future interventions are also discussed.
Health Applications of Gerontechnology, Privacy, and Surveillance: A Scoping Review
Authors: Carver Lisa F. , Mackinnon Debra
Published: June 2020

In this era of technological advances designed to assist older adults to age in place and monitor health challenges, the emphasis has been on the surveillance of older adults for their safety and the peace of mind of caregivers. This article focuses on two emerging gerontechnologies: wearables and smart home or ambient assistive living (AAL) devices. In order to explore the intersections of the ageing enterprise and surveillance capitalism, this scoping review addresses the following questions: (1) what are the existing technologies; (2) what are the privacy concerns raised by participants, researchers, and caregivers due to intended and unintended uses of these technologies? Specifically, this article synthesizes twenty relevant sources concerning the surveillance potentials of these gerontechnologies and the privacy implications for adults aged sixty-five and over. While these technologies may offer older adults greater autonomy/safety and caregivers peace of mind, their surveillance and privacy infringement potentials cannot be overlooked or cast as a trade-off. Amidst the automation of the care, collection, combination, and commodification of various forms of personal, health, and wellness metadata, the right to privacy, dignity, and ageing in place must remain central to the adoption and use of these technologies.

Configuraciones de ciudades en la Amazonía brasileña: el caso de Coari en el Amazonas
Authors: do Nascimento Seabra Vlamir
Published: June 2020

This article presents theoretical approaches on the concepts of rural and urban in the Western Amazon. The methodology used is a literature review and a case study. The rural and the urban are relevant themes in the investigations of the Group of Studies and Research on Territorial and Urban Planning, of the Federal University of Pará, as well as the discussions of the Center of Studies and Research of the Cities in the Brazilian Amazon of the Federal University of Amazonas. We analyze the case of the city of Coari in Amazonas, which underwent socio-spatial transformations since the arrival of the oil industry, when the financial transfer to the City Hall, referring to the royalties resources, begins. It discusses the transformations that have occurred and, consequently, how the theoretical concepts of rural and urban cannot be applied in their entirety, considering that the region of the western Amazon has certain particularities such as: the relationship with the forest and with the rivers still remains alive in the daily life of the population of Coari and, at the same time, the city's economy is linked to the oscillations of the international oil market, maintaining a culture of sponsorship and political patronage.

Authors: Gribakina Tatiana Eduardovna
Published: June 2020

This article explores the creation of the image of a Soviet woman within the Soviet cinematography. The subject of this research is the female image formed by the Russian cinematography at certain stages and its dynamics. The author suggest understanding of the image of woman as a combination of sensible images, which include representations on the place, role, functions, traits that are potentially common to her, but are yet to be formed and realized. Detailed analysis of the films of the early XX century allows examining creation of the female image, the expectations, moods, perceptions of the future presented in the films, as well as tracing the correlation between semantic content and its visualization. Due to the fact that the image was designed gradually, the author considered the key social and political factors that affected its creation and found reflection within it. Special contribution of the author into the research of this topic consists in demonstration of a relatively holistic image of a Soviet woman in cinematography, which was comprise bit by bit and transformed, meeting the challenges, demands and needs of society and the state.  
A comparative study on simulating flow-induced fracture deformation in subsurface media by means of extended FEM and FVM
Authors: Li Tingyu , Han Dongxu , Yang Fusheng , Yu Bo , Sun Dongliang , Wei Jinjia
Published: June 2020

Accurate and efficient simulation on the fluid flow and deformation in porous media is of increasing importance in a diverse range of engineering fields. At present, there are only several methods can be used to simulate the deformation of fractured porous media. It is very important to know their application scopes, advantages, and disadvantages for solving the practical problems correctly. Therefore, in this paper, we compared two numerical simulation methods for flow-induced fracture deformation in porous media. One is the Extended Finite Element Method (XFEM), which is based on the classical finite element method and can simulate strong or weak discontinuous problems. The other is developed within the finite-volume framework, termed Extended Finite Volume Method (XFVM). We designed three test cases, including single fracture, cross fractures and eight discrete fractures, to investigate the accuracy and efficiency of XFEM and XFVM. The reference solutions were provided by the commercial software, COMSOL, where the standard finite element method is implemented. The research findings showed that the accuracy of the XFEM was slightly higher than that of the XFVM, but the latter was more efficient. These results are likely to be useful in decision making regarding choice of solving methods for the multi-field coupling problem in fractured porous media.

Fortune Telling Rituals Using Incense in Modern Chinese Religious Practices
Authors: Voytishek Elena E. , Yao Song , Gorshkova Alexandra V.
Published: June 2020

Based on Chinese written sources and the authors' research field materials, the paper analyzes features of Taoist Buddhist practices using incense, as well as the purport of the 24 combinations that arise during fortune telling using three incense sticks – a practice used in rituals dating back to the early Middle Ages which still occupies a prominent place among China's religious practices today.
The techniques that are concurrently characteristic of Buddhist practices, Taoist services as well as traditional folk beliefs hold a prominent place during the ritual. General terminology is primarily used in the comments supplementing the rituals in the original sources. These religious rituals involve ancient representations of Heaven as a “source of moral definitions” which reacts to human deeds through various signs, the teachings of the all-encompassing Qi as the energy of the universe and its numerological embodiment, worldview ideas including ancient Taoist beliefs and practices related to the cult of ancestors as well as worship of Heaven and various spirits, and basic Buddhist postulates of rebirth, karma and retribution for committed acts. Conducting fortune telling rituals using incense naturally embodied folk beliefs, which was instrumental in the ongoing teachings of morality to many generations across almost two millennia.
Tables and comments on the 24 fortune telling combinations are published in Russian for the first time.

Objetivo: Discutir com base em artigos científicos a substituição de animais por recursos tecnológicos em ensaios experimentais no ensino superior na área de saúde e sua evolução no Brasil. Métodos: Realizou-se revisão sistemática nas bases: National Library of Medicine National Institutes of Health dos EUA (PUBMED), Medical Literature Analysis and Retrieval System Online (MEDLINE), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), e Scientific Eletronic Library Online (SCIELO), utilizando os descritores: “bioética,” “bem-estar animal” “ética em pesquisa”, “experimentação animal”. Foram selecionados 7 artigos publicados em português e inglês no período de 2000 a 2017. Resultados: Nos últimos anos tem-se discutido muito a utilização de animais em pesquisas e no ensino superior. É uma prática antiga, ainda fere a sensibilidade humana, e provoca discussões entre estudantes, professores e a sociedade, que vão além da barreira ética, pois, muitos questionam a real eficácia dessa metodologia de ensino diante dos avanços tecnológico-científico disponível atualmente. Considerações Finais: Nesse cenário surgem alternativas que substituem o uso de animais em ensaios experimentais por programas de computadores, softwares ou manequim que mimetizam parâmetros fisiológicos. Evidenciou-se que a utilização de animais como modelo experimental está passando por processo de transformação tanto nos aspectos legais como metodológicos.

Objetivo: Realizar uma revisão narrativa das repercussões no comportamento e na saúde mental da população vulnerável e de medidas adotadas, no enfrentamento da pandemia do COVID-19. Revisão bibliográfica: Devido imprevisibilidade da pandemia do COVID-19, consequências mentais, são cada vez mais relatadas. Suspeitos, infectados, profissionais de serviços essenciais, os que vivem sozinhos, instituições como casas de repouso, prisões, centros de detenção de imigrantes, idosos, portadores de doença mental, imunodeprimidos e sem-teto, estão mais propícios aos danos de saúde física e mental. A intensificação de sentimentos como medo, raiva, estresse, insegurança e frustração estão associados a um maior risco de desenvolvimento para transtornos psiquiátricos. Para minimizar esses sentimentos, é relevante que meios de comunicação emitam notícias verdadeiras sobre o enfrentamento da pandemia e programas de lazer e cultos religiosos online sejam identificados, por ressaltarem emoções positivas. Considerações finais: As repercussões da pandemia do COVID-19 são comparadas a desastres naturais e guerras, pelo receio em adoecer, ficar desempregado, desamparado, ser estigmatizado caso venha a se infectar e, o medo de morrer. A sensação de incerteza quanto ao futuro econômico e educacional traz também implicações na saúde mental. Estratégias sociais, educacionais, econômicas devem ser implantadas para minimizar os danos causados pela COVID-19.
Politisasi Bahasa Melalui Eufemisme dalam Program Berita di Televisi
Authors: Hermaliza  , Ermawati. S
Published: June 2020

This study discussed the politicization of language through euphemisms that conducted at the time of news broadcasts on television stations by noticing the background of the use of the euphemisms. Euphemism in the mass media is not merely aimed at replacing taboo words, but rather is ideological politics. The problem raised in this study was "How was the politicization of language through euphemisms in news programs on television in terms of its use?". The purpose of this study was to describe the form and function of politicizing the meaning of words through euphemisms in news programs contained on television. This research was a descriptive research. Data analysis was performed using content analysis and then explained in accordance with the research findings. Based on the results of the study, the authors found that politicized euphemisms in the TVone news program amounted to 30 euphemisms with several reasons why the euphemisms were chosen and used include: (1) to smooth out words so that other people are not offended, (2) to keep things secret, (3) for diplomacy or berororis, (4) to disguise meaning, (5) to avoid panic and fear, (6) to respect others.
Hole-Hole Tamm-Dancoff-Approximated Density Functional Theory: A Highly Efficient Electronic Structure Method Incorporating Dynamic and Static Correlation
Authors: Bannwarth Christoph , Yu Jimmy K. , Hohenstein Edward G. , Martínez Todd J.
Published: June 2020

The study of photochemical reaction dynamics requires accurate as well as computationally efficient electronic structure methods for the ground and excited states. While time-dependent density functional theory (TDDFT) is not able to capture static correlation, complete active space self-consistent field (CASSCF) methods neglect much of the dynamic correlation. Hence, inexpensive methods that encompass both static and dynamic electron correlation effects are of high interest. Here, we revisit hole-hole Tamm-Dancoff approximated (hh-TDA) density functional theory for this purpose. The hh-TDA method is the hole-hole counterpart to the more established particle-particle TDA (pp-TDA) method, both of which are derived from the particle-particle random phase approximation (pp-RPA). In hh-TDA, the N-electron electronic states are obtained through double annihilations starting from a doubly anionic (N+2 electron) reference state. In this way, hh-TDA treats ground and excited states on equal footing, thus allowing for conical intersections to be correctly described. The treatment of dynamic correlation is introduced through the use of commonly-employed density functional approximations to the exchange-correlation potential. We show that hh-TDA is a promising candidate to efficiently treat the photochemistry of organic and biochemical systems that involve several low-lying excited states – particularly those with both low-lying pipi* and npi* states where inclusion of dynamic correlation is essential to describe the relative energetics. In contrast to the existing literature on pp-TDA and pp-RPA, we employ a functional-dependent choice for the response kernel in pp- and hh-TDA, which closely resembles the response kernels occurring in linear response and collinear spin-flip TDDFT.
An Enzymatic Toolkit for Selective Proteolysis, Detection, and Visualization of Mucin-Domain Glycoproteins
Authors: Shon D. Judy , Malaker Stacy , Pedram Kayvon , Yang Emily , Krishnan Venkatesh , Dorigo Oliver , Bertozzi Carolyn
Published: June 2020

Densely O-glycosylated mucin domains are found in a broad range of cell surface and secreted proteins, where they play key physiological roles. In addition, alterations in mucin expression and glycosylation are common in a variety of human diseases, such as cancer, cystic fibrosis, and inflammatory bowel diseases. These correlations have been challenging to uncover and establish because tools that specifically probe mucin domains are lacking. Here, we present a panel of bacterial proteases that cleave mucin domains via distinct peptide- and glycan-based motifs, generating a diverse enzymatic toolkit for mucin-selective proteolysis. By mutating catalytic residues of two such enzymes, we engineered mucin-selective binding agents with retained glycoform preferences. StcEE447D is a pan-mucin stain derived from enterohemorrhagic Escherichia coli that is tolerant to a wide range of glycoforms. BT4244E575A derived from Bacteroides thetaiotaomicron is selective for truncated, asialylated Core 1 structures commonly associated with malignant and pre-malignant tissues. We demonstrated that these catalytically inactive point mutants enable robust detection and visualization of mucin-domain glycoproteins by flow cytometry, Western blot, and immunohistochemistry. Application of our enzymatic toolkit to ovarian cancer patient ascites fluid and tissue slices facilitated characterization of patients based on differences in mucin cleavage and expression patterns.
In Silico Docking Studies of Antimalarial Drug Hydroxychloroquine to SARS-CoV Proteins :An Emerging Pandemic Worldwide
Authors: Jokhakar Priyanka H. , Kalaria Rishee , Patel Hiren K.
Published: June 2020

This computational study comprises screening and prediction of interaction of selected antimalarial drug hydroxychloroquine with targeted two proteins of coronavirus. One is SARS enveloped E pantameric ion channel protein and another is SARS-CoV-2 main apoprotein protease. Both are vital for viral attachment and entry to the host cell for infection. After molecular protein docking with different confirmations, stable interacting complex of ligand and macromolecules were obtained. Interacting Lysine, Threonine and Tyrosine of E protein were found for participation of stable interaction with selected drug having docking affinity energy of -6.3kcal/mol. For apoprotein protease stable confirmation was screened out having bonding Threonine residue with same drug of energy -6.0 kcal/mol. Irreversible covalent bond formation and van der Waals interaction favours the selectivity and stability of both targeted proteins towards selected drug. Conventional as well as hydrophobic interactions are found in Ligplot and Discovery studio analysis also indicates stabilized confirmations between ligand and drug. Thus, this study delivers the putative mechanism of the drug interactions to target proteins hence comprising landmark for future investigation for antimalarial hydroxychloroquine as anti COVID 19 drug in this experimental time.

Published: June 2020

A new series of iron(II) complexes—[Fe(BPP-CN)2](X)2, X = BF4 (1a-d) or ClO4 (2)—belonging to the [Fe(BPP-R)2]2+ (BPP = 2,6-bis(pyrazol-1-yl)pyridine) family of complexes showed abrupt and hysteretic, that is, bistable, spin-crossover (SCO) characteristics. Among the complexes, the lattice solvent-free complex 2 showed a stable and complete SCO (T1/2 = 241 K) with a thermal hysteresis width (ΔT) of 28 K, the widest ΔT so far reported for a [Fe(BPP-R)2](X)2 family of complex, showing abrupt SCO. The reproducible and bistable SCO shown by the relatively simple [Fe(BPP-CN)2](X)2 series of molecular complexes is encouraging to pursue [Fe(BPP-R)2]2+ systems for the realization of technologically relevant SCO complexes.

Published: June 2020

Coronaviruses are a family of viruses that cause illness such as respiratory diseases or gastrointestinal diseases. Respiratory diseases can range from the common cold to more severe diseases. A novel coronavirus outbreak was first documented in Wuhan, Hubei Province, China in December 2019. The World Health Organization (WHO) has declared the coronavirus disease 2019 (COVID-19) a pandemic. A global coordinated effort is needed to stop the further spread of the virus. A novel coronavirus (nCoV) is a new strain that has not been identified in humans previously. Once scientists determine exactly what coronavirus it is, they give it a name (as in the case of COVID-19, the virus causing it is SARS-CoV-2).

Published: June 2020

In this paper Al2O3 + 13 wt% TiO2 ceramic coatings manufactured by Atmospheric Plasma Spraying (APS) have been investigated. The commercial feedstock materials, Metco 6221 (top coat) and Amdry 4535 (bond coat) have been deposited on stainless steel coupons. The main goal of researches was to determine the influence of critical plasma spray parameters (CPSP) on structure and properties of the coatings. In present studies, the electrical power was a variable parameter. Coatings have been characterized by in the terms of microstructure, topography, bond strength adhesion, fracture toughness and wear resistance. As a result, it was observed, that coatings sprayed with higher value of the electrical power exhibit higher mechanical properties due to better cohesion as well as higher melting degree.

Viator vitreocola gen. et sp. nov. (Stylonematophyceae), a new red alga on drift glass debris in Oregon and Washington, USA
Authors: Hansen GI , West JA , Yoon HS , Goodman CD , Goër SLD , Zuccarello Giuseppe
Published: June 2020

© 2019 The Korean Society of Phycology. A new encrusting red alga was found growing abundantly on glass debris items that drifted ashore along the coasts of Oregon and Washington. These included discarded fluorescent tubes, incandescent light bulbs, capped liquor bottles, and ball-shaped fishing-net floats. Field collections and unialgal cultures of the alga revealed that it consisted of two morphological phases: a young loosely aggregated turf and a mature consolidated mucilaginous crust. The turf phase consisted of a basal layer of globose cells that produced erect, rarely branched, uniseriate to multiseriate filaments up to 500 µm long with closely spaced cells lacking pit-plugs. These filaments expanded in size from their bases to their tips and released single cells as spores. At maturity, a second phase of growth occurred that produced a consolidated crust, up to 370 µm thick. It consisted of a basal layer of small, tightly appressed ellipsoidal-to-elongate cells that generated a mucilaginous perithallial matrix containing a second type of filament with irregularly spaced cells often undergoing binary division. At the matrix surface, the original filaments continued to grow and release spores but often also eroded. Individual cells, examined using confocal microscopy and SYBR Green staining, were found to contain a central nucleus, a single highly lobed peripheral chloroplast without a pyrenoid, and numerous chloroplast nucleoids. Morphological data from field and culture isolates and molecular data (rbcL, psbA, and SSU) show that this alga is a new genus and species which we name Viator vitreocola, “a traveller on glass.”
Gracilaria phuquocensis sp. nov., a new flattened Gracilaria species (Gracilariales, Rhodophyta), previously recognized as G. mammillaris, from the southern coast of Vietnam
Authors: Le HN , Muangmai N , Kheauthong S , Sun Z , Zuccarello Giuseppe
Published: June 2020

© 2019 Japanese Society of Phycology Flattened Gracilaria species are widely distributed along the coasts of the South China Sea with more than 20 species recorded. Within the South China Sea, Gracilaria mammillaris has only been reported from Vietnam, but this species is likely restricted to the western Atlantic. This study aimed to reevaluate the taxonomic status of Vietnamese specimens of ‘G. mammillaris’ using combined morphological and molecular data. Our data clearly indicated that Vietnamese specimens were morphologically and genetically distinct from authentic G. mammillaris from the western Atlantic, and also other described flat Gracilaria species. We, therefore, propose that specimens from Vietnam originally identified as G. mammillaris be designated as a new species, Gracilaria phuquocensis sp. nov. Morphologically, G. phuquocensis can be distinguished from other flat Gracilaria species by its small thallus size, narrower blades, many medullary layers, abundant basal nutritive filaments within mature cystocarps, and tetrasporangial nemathecium. Our rbcL sequence analyses showed that the new species was sister to Gracilaria rhodymenioides from Thailand, and these two species formed a clade with cylindrical Gracilaria species. Our study contributes to clarification of the taxonomic status of misidentified specimens attributed to the flattened Gracilaria species in the South China Sea.

©The Author(s) 2018. Published by Oxford University Press. Remotely activated cameras are increasingly used worldwide to investigate the distribution, abundance and behaviour of animals. The number of studies using remote cameras in urban ecosystems, however, is low compared to use in other ecosystems. Currently, the time and effort required to classify images is the main constraint of this monitoring technique. To determine whether, or not, citizen science might help overcome this constraint, we investigated the engagement, accuracy and efficiency of citizen scientists providing crowd-sourced classifications of animal images recorded by remote cameras in Wellington, New Zealand. Classifications from individual citizen scientists were in 84.2% agreement with the classifications of professional ecologists. Aggregating the classifications from three citizen scientists per image, and excluding false triggers and unclassifiable classifications increased their overall accuracy to 97.6%. Classifications by citizen scientists also improved if animal movement was highlighted in the images. The likelihood of citizen scientists correctly classifying images was influenced by their previous accuracy, their self-assessed confidence, and the species reported. Weighting the citizen scientist classifications based on their ability to correctly identify animals reduced from 3 to 2 the number of classifications required per sequence to classify >95% of the photographs containing cats. Citizen science is an accurate and efficient approach for classifying remote camera data from urban areas, where most of the animals are familiar to the participants. We demonstrated how appropriate tools and accounting for the accuracy of citizen scientists, allows project managers to maximise the effort of citizen scientists while ensuring high-quality data.
Assessing the suitability of non-invasive methods to monitorinterspecific interactions and breeding biology of the South Georgian diving petrel (Pelecanoides georgicus)

© The Ornithological Society of New Zealand Inc. We assessed the impact of interspecific interactions on the breeding success of the South Georgian diving petrel (Pelecanoides georgicus; SGDP), a Nationally Critical seabird species, by monitoring 20 burrows at Codfish Island (Whenua Hou), with remote cameras. Additionally, we tested the utility of remote cameras to study the breeding biology and activity patterns of the SGDP by pairing 5 remote cameras with RFID readers. We recorded 7 different species at SGDP burrow entrances. The common diving petrel (P. urinatrix) likely caused two monitored burrows to fail. These results suggest that remote cameras are useful tools to study such interactions. However, the cameras had extremely low SGDP detection rates (mean = 10.86%; se = 7.62%) when compared to RFID readers. These low detection rates may be explained by the small body size and the speed at which SGDPs enter/leave burrows. Therefore, remote cameras, or at least the model and setup we used, appear unsuitable to study breeding biology and activity patterns in this seabird species.

© 2016 by the Ecological Society of America. Encounter competition is interference competition in which animals directly contend for resources. Ecological theory predicts the trait that determines the resource holding potential (RHP), and hence the winner of encounter competition, is most often body size or mass. The difficulties of observing encounter competition in complex organisms in natural environments, however, has limited opportunities to test this theory across diverse species. We studied the outcome of encounter competition contests among mesocarnivores at deer carcasses in California to determine the most important variables for winning these contests. We found some support for current theory in that body mass is important in determining the winner of encounter competition, but we found that other factors including hunger and species-specific traits were also important. In particular, our top models were "strength and hunger" and "size and hunger," with models emphasizing the complexity of variables influencing outcomes of encounter competition. In addition, our wins above predicted (WAP) statistic suggests that an important aspect that determines the winner of encounter competition is species-specific advantages that increase their RHP, as bobcats (Lynx rufus) and spotted skunks (Spilogale gracilis) won more often than predicted based on mass. In complex organisms, such as mesocarnivores, species-specific adaptations, including strategic behaviors, aggressiveness, and weapons, contribute to competitive advantages and may allow certain species to take control or defend resources better than others. Our results help explain how interspecific competition shapes the occurrence patterns of species in ecological communities.

The study was arranged as factorial experiment in a completely randomized design with three applications of cultivar (Parus and Gaviota), 24- Epi brassinolide concentrations (0, 1 and 2 mgl-1) and temperature (normal and stress) as three replications. Some of the measuring characteristics showed that there was a significant difference among the treatments. Under heat stress conditions, foliar application of 24- Epi brassinolide at 1 mgl-1 concentration increased the amount of catalase and superoxide dismutase activity in leaves of Parus cultivar. Both cultivars fruits showed the highest total soluble solid contents in treatment 24- Epi brassinolide spraying at 2 mgl-1 concentrations under normal temperature. The highest total phenolics was in Gaviota cultivar treated with 24- Epi brassinolide spraying at 2 mgl-1 concentrations under normal temperature. Both cultivars had the lowest flavonoid in treatments without 24- Epi brassinolide and with 24- Epi brassinolide at 2 mgl-1 concentrations under heat stress conditions. In Gaviota cultivar, application of high concentration of 24- Epi brassinolide (2 mgl-1) prevented the reduction of total anthocyanin under heat stress conditions.

Fritillaria imperialis L. (Terslale) Türkiye’de doğal olarak yetişen ve süs bitkisi olarak kullanılan bir türdür. Bu tür doğada morfolojik olarak yüksek bir genetik varyasyon göstermektedir. Van Gölü havzasından toplanan 74 F. imperialis genotipi arasındaki genetik çeşitliliği belirlemek amacıyla yürütülen bu çalışmada, 19 farklı iPBS-Retrotranspozon primeri kullanılmıştır. Kullanılan 19 primerin tamamı %100 oranında polimorfizm gösteren toplam 94 bant oluşturmuştur. Primer başına düşen ortalama bant sayısının 4.94, ortalama polimorfizm bilgi içeriğinin (PIC) ise 0.58 olduğu belirlenmiştir. En düşük bant veren primer 2 bant oluştururken, en yüksek bant veren primer 10 bant oluşturmuştur. Ortalama etkili allel sayısının 1.50, Shannon bilgi indeksinin 0.47, gen çeşitliliğinin ise 0.30 olduğu saptanmıştır. Elde edilen sonuçlar, Van Gölü havzasından toplanan ters lale genotiplerindeki genetik farklılığın önemli düzeyde olduğunu ortaya koymuştur. Terslale genotiplerinde ilk kez iPBS-Retrotranspozon markırları kullanılarak genetik çeşitliliğin belirlenmesine yönelik olarak yürütülen bu çalışma, iPBS-Retrotranspozon markır sisteminin bu türde başarılı bir şekilde uygulanabileceğini ortaya koymuştur. Elde edilen veriler, terslale üzerinde yürütülecek ıslah çalışmaları için ön bilgi oluşturacak niteliktedir.
