Polymerization degree-dependent changes in the effects of in vitro chitosan treatments on photosynthetic pigment, protein, and dry matter contents of Ipomoea purpurea
Authors: Acemi Ruhiye Kıran , Acemi Arda 
Published: October 2019

Abstract
Morning Glory (Ipomoea purpurea (L.) Roth.) is a climbing plant known for its ornamental properties and ease of cultivation in temperate climates. Quality and colour of flowers and leaves, especially in the production of ornamentals, are important parameters both for producers and for customers. This study aimed to investigate the changes in photosynthetic pigment, protein and dry matter content of in vitro-propagated I. purpurea following chitosan treatment with different polymerization degrees (DP) and to determine the indirect effect of this biopolymer on leaves of the plant. Nodal explants of I. purpurea were cultured in medium supplemented with 5, 10 and 20 mg L−1 concentrations of a chitosan oligomers mixture with a variable degree of polymerization (DP) ranging from 2 to 15 or chitosan polymer with DP of 70. It was found that both oligomeric and polymeric chitosan treatments increased chlorophyll-a contents in the leaves when compared to the chitosan-naïve control group. Polymeric chitosan stimulated chlorophyll-b and carotenoid synthesis more effectively than the oligomer mixture. Also, 10 mg L−1 polymeric chitosan better triggered total protein production and plant dry matter content in I. purpurea. The results of this study showed that, due to their stimulatory effects on photosynthetic pigment, protein and plant dry matter production, chitosan oligomers at low concentration and polymers at moderate concentration might be considered as safe and natural biostimulants for ornamental plants which could affect the plant’s attractiveness and commercial success.

Published: October 2019

Abstract
One of the most effective methods for the immobilization of toxic metals involves the use of minerals from the apatite supergroup. The formation of cadmium chlorapatite may lead to successful entrapping of cadmium; thus, it is important to examine the solubility constant to determine the stability of cadmium in the the apatite structure. Cadmium chlorapatite was synthetized and characterized by X-ray diffraction, infrared spectroscopy, Raman spectroscopy, and scanning electron microscopy. The solubility constant (log) Ksp of cadmium chlorapatite was -65.58. The Gibbs free energy of formation of cadmium chlorapatite reached -3950.48 kJ mol−1. The solubility constant turned out to be low but was enough for cadmium chlorapatiteto be considered a very stable compound..

Published: October 2019

Abstract
In this article, we report the synthesis and characterization of silver dispersed poly(m-toluidine-co-2-bromoaniline) copolymer synthesized by chemical oxidative polymerization method. The synthesized copolymer composites were subjected to different analytical characterization methods, such as FT-IR, UV, XRD, SEM, photoluminescence and electrical conductivity studies. All the polymer samples are found to be soluble in common organic solvents. UV absorption spectra show a red shift when silver nanoparticles are dispersed in the copolymer. The characteristic peaks observed in FT-IR spectra confirm the formation of the copolymer. XRD pattern reveals the crystalline nature of the copolymer composites and sharp peaks in the spectra confirm the presence of silver particles. The silver nanoparticles change the surface morphology in the form of perfect encapsulation. The electrical conductivity of the polymer composites is found to vary from 10−4 S/cm to 10−6 S/cm. PL study reveals the charge transfer between the copolymer and the silver particles.

Published: October 2019

Abstract
The process of pattern recognition in the biometrics is particularly important. The patterns can differ from each other a lot, and even the samples can be significantly different from the templates. The Artificial Neural Networks can be applied as a universal approximator to recognize the patterns with more flexibility. However the topology of the networks determines the processing time and complexity of the hardware of the physical environments. The Genetic Algorithms can be used with success in optimization problems like in this situation, the topology of the neural network is more optimal if we apply the Genetic Algorithms. This study introduce an algorithm in which a tailor made algorithm correcting the topology to enhance the effectiveness of the process.

pARTicipate: Art as Self-Expression for Persons with Aphasia
Authors: Khaledan Roujan , Tomlinson Heather A. 
Published: October 2019

Background
Aphasia is an acquired communication disorder resulting from a stroke or traumatic brain injury. Persons with Aphasia (PWA) have deficits in language comprehension and expression. Loss of communicative functions can be isolating for PWA as they may face barriers to accessing community-based leisure programs. Aphasia-friendly materials, visuals and simple written or oral instructions, can reduce such barriers and support communicative access.
Objective
The pARTicipate project is a student-initiated art group that was piloted with the aim of encouraging PWA to trial an art class in a communicatively accessible and low-risk environment, as part of an outpatient rehabilitation program. By using a life participation approach for aphasia, this project aimed to promote participants’ discovery, or rediscovery, of a hobby.
Methods
Four PWA completed six art projects over 9 weeks. Communicative access was enhanced by using aphasia-friendly instructions and demonstrations to teach the projects. Participants showcased their projects and taught their skills to family and community members on the final “Share Day”.
Results
Qualitative and quantitative data was gathered from satisfaction surveys. One hundred percent of the participants indicated that they enjoyed sharing their art with the community, and that they would join the group again if it was offered. Additionally, all participants indicated they would be likely to continue exploring art in the future.
Conclusions
It is expected that the skills learned by PWAs in pARTicipate may help increase their confidence about participating in other community-based art classes. As well, continuing to use these skills may help participants develop a sense of belonging to the artistic community. By learning to incorporate personal symbols, PWA can be deliberate in their use of art for self-expression in the future. Finally, PWA were empowered to assume a leadership role during “Share Day”. Having the opportunity to teach newly acquired artistic skills to their family and community members promoted positive feelings about the self and served to reveal their cometencies.

Introduction.Annually, there are several patients attended the Center for Diagnosis and Prevention of Tick-borne Infections in Irkutsk after bites of ticks that happened outside the Pribaikalye region or abroad. In such cases, the attacking ticks do not belong to convenient species that are usual for Eastern Siberia. Consequently, the spectrum of pathogenic microorganisms transmitted by these ticks may significantly differ from those that are detected by usual laboratory tests. Thus, both physicians and laboratory personnel may have difficulties in proper detection and identification of pathogens as well as in diagnosing and treating of such patients.The purposeof the study was the analysis of potential risks of human infection with the pathogens that are common in foreign countries outside the Russian Federation.Material and methods.The article uses information from electronic databases created by the authors during 2007-2017.Results and discussion.During 11 years of observations, 52 tick bites were registered in 20 countries, with 48 of them in the Eastern Hemisphere (92.3 %), three (5.8 %) in the United States and one (1.9 %) in the Republic of Cuba. The results indicate a real danger of infection by tick-borne pathogens of people traveling as the tourists and with business purposes to the countries of Europe, Asia and America. Conclusion.It is necessary to improve the existing algorithm for diagnosis, prevention and treatment for people bitten by ixodid ticks outside the Russian Federation, taking into account the possibility of infection by inconvenient imported infections.
Evaluation of the Persistence of Three Larvicides Used To Control Aedes aegypti In Arapiraca, Northeastern Brazil
Authors: Amorim Quesia Santos , da Rocha Bauzer Luiz Guilherme Soares , Aparecida Braga Ima , Lima José Bento Pereira 
Published: October 2019

ABSTRACTThe chemical control of the mosquito Aedes aegypti is a great challenge worldwide, since several populations of this species are already resistant to traditional insecticides, such as temephos. In Brazil, alternative larvicides, such as Bacillus thuringiensis israelensis (Bti) and pyriproxyfen, have been used more recently. In this study we evaluated the persistence of pyriproxyfen (Sumilarv 0.5%G), 2 commercial formulations of Bti (Vectobac WDG and Vectobac G), and temephos (Fersol 1G) under field and simulated field conditions with treatments exposed to sun and shadow. In the field tests, the 2 formulations of Bti presented less persistence in the 8th wk of evaluation (46% and 37% positivity) compared with temephos (3.6% and 6.8% positivity) and Sumilarv (6.6% and 3.8% positivity) in containers exposed to the sun and shadow, respectively. In the simulated field trial, temephos and the 2 formulations of Bti presented high persistence (100% mortality at 8th wk) when applied in the water box and in deposits placed in the shade. In containers exposed to the sun, the persistence of these products was lower (&gt;80% mortality by temephos after 4 wk, Bti formulations for 3 wk, and Sumilarv for 6 wk). Based on these data, however, Sumilarv presented better performance in the containers exposed to the sun than the 2 formulations of Bti (Vectobac G and Vectobac WDG), which were affected by the sun.

Published: October 2019

ABSTRACTAedes aegypti is a vector of many significant arboviruses worldwide, including dengue, Zika, chikungunya, and yellow fever viruses. With vector control methodology pivoting toward rearing and releasing large numbers of insects for either population suppression or virus-blocking, economical remote (sentinel) surveillance methods for release tracking become increasingly necessary. Recent steps in this direction include advances in optical sensors that identify and classify insects based on their wing beat frequency (WBF). As these traps are being developed, there is a strong need to better understand the environmental and biological factors influencing mosquito WBFs. Here, we developed new untethered-subject methodology to detect changes in WBFs of male and female Ae. aegypti. This new methodology involves directing an ultrasonic transducer at a free-flying subject and measuring the Doppler shift of the reflected ultrasonic continuous wave signal. This system's utility was assessed by determining its ability to confirm previous reports on the effect of temperature, body size, and age on the WBFs generated from acoustic or optical-based experiments. The presented ultrasonic method successfully detected expected trends for each factor for both male and female Ae. aegypti without the need for subject manipulation and potential impediment of natural flight dynamics due to tethering. As a result, this ultrasonic methodology provides a new method for understanding the environmental and physiological determinants of male and female WBFs that can inform the design of remote mosquito surveillance systems.

Published: October 2019

ABSTRACTFor the 1st time, collections of adult female Aedes thibaulti are reported from Massachusetts. Initial collections occurred in 2016 and again in 2017 and 2018. This mosquito was found at 35 locations within 28 municipalities, including the city of Boston. Most of the Ae. thibaulti were collected with the Centers for Disease Control and Prevention miniature light traps baited with CO2. Collections were made from epidemiological (EPI) wk 22 to 35 with a peak at EPI wk 24. Although larvae have not yet been collected, the most common wetland types adjacent to collection sites were forested wetlands, which is consistent with the known larval habitat of this mosquito species. Aedes thibaulti is likely established in the state of Massachusetts.

Authors: Haas-Stapleton Eric J. , Barretto Miguel C. , Castillo Erika B. , Clausnitzer Ryan J. , Ferdan Robert L. 
Published: October 2019

ABSTRACT
An unmanned aircraft system (UAS; i.e., drone) with an attached multispectral camera was used to quantify accumulated surface water on a 0.54-km2 tidal marsh that abuts San Francisco Bay, CA, USA. The results of the survey showed unequal accumulation of surface water and provided information for focused inspections of potential mosquito breeding areas and identified areas where existing ditches needed improvement for increasing water circulation in the marsh to reduce mosquito breeding. The UAS was also outfitted with a high-magnification zoom video camera and piloted at varying heights to measure the video camera's ability to visualize immature mosquitoes in 2 small containers of contrasting colors during simulation tests in a marsh habitat. Immature mosquitoes could be seen clearly in white or black containers at heights up to 14 and 8 m, respectively. An artificial intelligence algorithm identified mosquito larvae and pupae in videos of the white tray with 94.1% and 52.8% accuracy, respectively. Together, our studies show that an UAS equipped with multispectral and zoom cameras provides a means for vector control agencies to rapidly and quantitatively assess the landscape for the presence of surface water and mosquito larvae.

Demarcating a Linguistic Expert’s and an Authorship Investigator’s Competencies When Examining Copyright and Related Rights Objects
Authors: Kuznetsov V. O. , Kryuk E. K. 
Published: October 2019

A controversial issue of the demarcation between a linguistic expert’s and an authorship investigator’s competencies when conducting forensic examinations in cases related to copyright and related rights violations is considered. In this category of cases there is mainly a need to deal with the task of ascertaining particularities of texts related to the fact of plagiarism that is the comparison of texts to reveal matching fragments, presence of borrowing, its direction which is the task of a linguistic expertise. Tasks which fall under the authorship investigator’s purview are associated with the examination of written language skill and aim to determine the authorship and text drafting conditions. Formerly researchers did not separate the tasks of linguistic and authorship investigations indicating the lack of methodological development of the issue. The article suggests some methodological approaches to solving the main tasks of linguistic expertise on cases involving copyright and related rights violations developed as a result of an overview of the practice of conducting such examinations in the Russian Federal Centre of Forensic Science of the Russian Ministry of Justice.

When considering land disputes, a court examines a large amount of evidence. In this forensic land survey expertise has taken a special place since its findings often form the basis of the court decision. The correct and prompt consideration of the dispute depends on the quality work of an expert.The paper reviews a range of problems emerging when appointing a land survey expertise, preparing materials for the forensic examination, assessing forensic expert opinions and other evidence by the court. Inter alia, it is essential to correctly determine the type of examination, the list of necessary documents to conduct it, to estimate the duration of the study. The author reveals the possibilities of expansion of a specialist’s advisory activities at the expertise appointment stage to reduce the time of its conduct.
PRODUCTIVITY OF GRASSLAND IN A CHANGING CLIMATE
Authors: Kurhak V. , Bohovin A. 
Published: October 2019

Climate warming, which began in the second half of XIX century, and with a certain intensity continues today, cannot but be reflected in the future on the structural and functional organization of grasslands and their productivity, as well as on strategic methods of their improvement.
Our 20-years long studies showed that phytocenosis respond to climate aridization through a significant decrease in performance even on low-lying meadows with a shallow (1-2 m below the ground) subterranean waters. In dry years, the productivity of most grass mixtures with a predominance in their composition meso-phytes, when compared with their average annual productivity in all years of research in these conditions, decreased by 26%-36%. However, environmental and biological structure of cenosis in this type of habitat remained stable.
At the watershed habitat, where moisture is supplied only due to precipitation, more stringent conditions for grasses are formed due to the climate warming. This not only leads to poor performance, but also to changes in ecological and biological structure in terms of strengthening of cenosis xerophytization, hence the need to improve the range of perennial grasses and technologies for improvement and use of grasslands.
The article includes an analysis of modern methods to provide the Ukrainian grasslands with composition of species and varieties of perennial grasses. It also outlines the main directions of their improvement in accordance with the regional topoecological composition due to the climate warming.
