Self-Limiting Electrospray Deposition for the Surface Modification of Additively Manufactured Parts
Authors: Kovacevich Dylan A. , Lei Lin , Han Daehoon , Kutznetsova Christianna , Lee Howon , Singer Jonathan
Published: October 2019

Electrospray deposition (ESD) is a spray coating process that utilizes a high voltage to atomize a flowing solution into charged microdroplets. These self-repulsive droplets evaporate as they travel to a target substrate, depositing the solution solids. Our previous research investigated the conditions necessary to minimize charge dissipation and deposit a thickness-limited film that grows in area over time through self-limiting electrospray deposition (SLED). Such sprays possess the ability to conformally coat complex three-dimensional objects without changing the location of the spray needle or orientation of the object. This makes them ideally suited for the post-processing of materials fabricated through additive manufacturing (AM), opening a paradigm of independent bulk and surface functionality. Having demonstrated three-dimensional coating with film thickness in the range of 1-50 µm on a variety of conductive objects, in this study we employed model substrates to quantitatively study the technique’s limits with regard to geometry and scale. Specifically, we examined the effectiveness of thickness-limited ESD for coating recessed features with gaps ranging from 50 µm to 1 cm, as well as the ability to coat surfaces hidden from the line-of-sight of the spray needle. This was then extended to the coating of hydrogel structures printed by AM, demonstrating that coating could be conducted even into the body of the structures as a means to create hydrophobic surfaces without affecting the absorption-driven humidity response.

Cerebral Palsy (CP) is a common neurodevelopmental condition encountered by pediatricians. The condition may present itself in many different kinds of classification. In many cases, the cause of CP may not be apparent. Cerebral Palsy is always showing many deficits such as mental retardation, speech and language and oral motor problems. This project inspired from Elisya, a nine-year-old kid that has CP since born and she have the communication problems since she cannot speak to express her opinions and desires. The main focus on this project is to help to improve the communication issues among CP children. In order to assist the people with CP, the assistive tool is required to help them to communicate or interact with people around them. Assistive technology includes equipment, devices and software solutions that increase functional capabilities of people with disabilities and improve the quality of their lives. There are several Augmentative and Alternative Communication (AAC) devices for people with Cerebral Palsy that are not able to speak. One of the ways to make this happen is to implement the AAC technology with mobile technology by developing a mobile application named as Make Me Speak and React Native technology in order to build the cross platform for this application since the application should be run on IOS and Android platform so it’s easier for other people to bring it anywhere and use it at any time. It also involves CP centres and school to do experimental studies for this project. There are several studies shows that AAC technology can help in enhancing the speech and language development and in this project, the suggested mobile application should be friendly to our language and culture of our nation, Malaysia and the project is in line with the social innovation in the Eleventh Malaysia Plan (RMK-11).

CROSS MEDIA AUDIENCE OF INFORMATIONAL AGENCY “112.UA”
Authors: Lepka Yana
Published: October 2019

The relevance of research is caused by the fact that cross-medіa
has become an integral feature of informational space functioning. The main feature of cross-media is based on functioning on several media platforms. Specifically, the informational agency “112.ua” has eight of such media platforms: the web portal “112.ua”, the TV channel “112 Ukraine”, the mobile application “News 112”, the interactive application “Witness 112”, the youtube channel and the profiles in three main social networks. The multi-media audience adopts the cross-media characteristics. This happens also with the assistance of top management “112.ua”: they use the special techniques to encourage the users to take information from different platforms. The main objective of the study is to identify the factors that encourage the audience to use the multiple platforms of cross-media “112.ua”. The audience ratings were revised and using the calculation method it was determined that the TV channel “112 Ukraine” was the main
platform with the biggest audience. The survey methodology helped to identify the most significant factors of attracting the cross-media audience: advertisement, announcement, availability, convenience, access to the archive. Using the method of classification, the factors were combined into several groups. The theoretical part and trends of cross-media were processed by using comparative-historical method and analysis of scientific literature. As a phenomenon cross-media is closely related to such terms as multiplatform, trans-media, convergence. The scientific works of Ukrainian and world researchers distinguish often a somewhat philosophical aspect of crossmedia from a purely technical phenomenon of multiplatform and transmedia. The main feature of cross-media communication is coverage of various media platforms. Another important element is users’ interactivity. The audience of multiplatform editionss has certainly the feature of crossmedia. Cross-media management encourages it to use several multiple platforms through such key factors as advertising, promotion, accessibility, convenience, ability to go back to missed or somewhat outdated topics. And the consumers come quite easily under this influence, because the world is changing and multiplatform becomes an integral part of functioning of information environment. This was proved by the example of the audience of the information agency “112.ua”. Only 10% of respondents do not show their mobility and ability to use several platforms of one cross-media edition.The results and conclusions of the study may be of interest for top management of multi-platform media and for those ones, who explore cross-media audience.

Biogas purification from carbon dioxide compounds due to can reduce the calorific value of methane (CH4). One application used in this case is adsorption using activated carbon. This study aims to simulate the absorption of CO2 using ANSYS R19.0 and to analyze percent adsorption, adsorption capacity and isothermal adsorption. Based on variations in bed height, flow rate and pressure, the highest percent percussion occurs at 10 cm bed height, 50 cm3/minute flow rate with a pressure of 1.4 atm and the lowest percent absorption occurs at 6 cm bed height, 150 cm3/minute flow rate with a pressure of 1.2 atm. Whereas the maximum absorption capacity occurs at 8 cm bed height, 50 cm3/minute flow rate at a pressure of 1.4 atm and minimum absorption capacity occurs at 8 cm bed height, flow rate of 150 cm3/minute at a pressure of 1 atm. This adsorption process occurs in the Langmuir isotherm with R2 approaching 1, which is equal to 0.9151. The optimization results were obtained at a flow rate of 50 cm3/minute, bed height 9.46 cm and 1.4 atm pressure.

El presente artículo se enfocó en comprender los rasgos que caracterizaron las Prácticas Educativas en un Aula Multigrado de una Institución Educativa Pública desde un Enfoque Inclusivo en Quinchía, Risaralda (2017). Fue necesario el uso de técnicas e instrumentos de recolección de información como; observación participante (videograbaciones), análisis documental (PEI, planeaciones, diarios de campo, trabajos de los estudiantes) y la entrevista semiestructurada; se utilizó una metodológica de corte comprensivo con un estudio de caso Etnográfico. El procedimiento se dio en 3 momentos: codificación abierta, axial y selectiva. Dando como resultado las categorías emergentes: Estrategias Didácticas, Clima Escolar y Gestión Escolar. De esta manera, se confrontaron las 3 técnicas e instrumentos en un proceso de validación por medio de la triangulación como momento clave para el análisis y discusión de los resultados. Se concluyó que la Practica Educativa, el modelo educativo flexible, la Política Institucional y el Ambiente Escolar, no dan respuesta desde el modelo Escuela Nueva a un enfoque Inclusivo sino desde el modelo Tradicional.

Nanoscale drugs differ in special physicochemical, biological, pharmacokinetic parameters. These properties can be used to provide targeted delivery, prolong the action of drugs, as well as reduce their side effects. An important problem that needs attention is the study of the potential risks arising from the treatment of such drugs. The aim of the study: analysis of the requirements of domestic and foreign regulators for the safety of nanoscale drugs. The paper presents the classification of the most promising nanosystems containing drugs, and an analysis of the existing principles for assessing their safety in Russia and abroad has been carried out. It was shown that when assessing the safety of nano-sized drugs, along with the properties of the active substance, it is necessary to take into account the properties of the nanosystem (polymer coating, carrier, etc.), related to its size, distribution pattern, charge of nanoparticles, and ability to induce oxidative stress. Domestic and foreign regulatory documents governing the procedure for assessing the safety of pharmacological substances derived from nanotechnology was analyzed. Conclusions: Despite the availability of recommendations from regulatory authorities, further improvement of the requirements for registration and safety assessment of nanoscale drugs is necessary. Further development of the regulatory framework governing the development, quality, efficiency and safety of nanomaterials in medicine is necessary, taking into account the structural issues of the active substance and nano-carriers.

Despite the inadequate evidence of effi cacy and safety of opioid use for the treatment of migraine, it has been reported that patients with moderate to severe migraine headaches are prescribed opioids. Migraineurs may experience serious health impacts from opioids such as headache-related disability, psychiatric and cardiovascular comorbidities. The reduction of the risk of opioid abuse and prevention of an opioid epidemic are important public health challenges. The aim of this study was to assess the awareness of opioid therapy for migraine and the frequency of use among Turkish patients with episodic and chronic migraine. Materials and methods: consecutive migraine patients were enrolled in this cross-sectional study. A semi-structured questionnaire was developed and used by the researchers to assess the patients’ awareness of an opiod treatment option and the frequency of use of opioids for migraine treatment. Results. One hundred two patients were enrolled, of which 72 had episodic migraine and 30 had chronic migraine. All subjects reported that they had not been offered or prescribed any kind of opioids by general practitioners and neurologists for their headache. Besides, only 7 % of patients declared that they had heard of opioid treatment for migraine but they had never consulted their doctors about its effects. Conclusions. Our fi ndings demonstrated that opioids were not preferred as an option for acute or preventive migraine treatment by Turkish migraineurs and their physicians. The reduction of opioid prescription will help to prevent the development of medication overuse and opiate-induced headaches and drug addiction.

The high tourism visit is a potential that can be utilized to encourage local economic progress, this can be done on condition that the increase in tourism visits must be followed by an increase in the ability of the government and local communities to be able to synergize the tourism potential and the local economy because if not, an increase in tourism visits only adds benefits for tourism business activists who are not local residents so that local residents receive more negative impacts than positive impacts from increased tourism visits. This must be addressed, one of which is the synergy of the tourism potential management program with the local economic program in the local government.

Yard land in urban areas has not been utilized for the cultivation of vegetables that are productive and economically profitable. This service program aims to improve the knowledge and skills of PKK members in verticultural and hydroponic vegetable cultivation. Thus, the members can use their yard more productively. The method used in this community service program is training, which consists of counseling as well as demonstrations and practice. Counseling is about the cultivation of vegetable plants vertically and hydroponically has increased the knowledge of participants, from initially not knowing about verticulture to know. The demonstration/practice of growing vegetables the next day made the participants better understand what was delivered in the previous counseling. This encourages the improvement of mothers' skills in growing vegetables vertically and hydroponically. This additional knowledge and skills encourage participants to practice in their own homes.

Published: October 2019

Communities of macroscopic red algae in rivers of the Upper Volga region and adjacent territories are considered. Their classification based on the Braun-Blanquet approach is proposed. Phytocoenoses belong to the class Lemaneetea fluviatilis and the order Lemaneetalia fluviatilis. Two alliances Lemaneion fluviatilis and Batrachospermion gelatinosi separate the plant communities of fast and slow flowing waters. The first mentioned alliance includes the association Lemaneetum fluviatilis only, the second one unites the associations Batrachospermetum gelatinosi, Batrachospermetum turfosi and the community Sirodotia suecica. Almost all syntaxa are published validly for the first time. The characteristics of syntaxonomical units are given. Data on species composition, structure, ecology and distribution of the revealed phytocoenoses are presented. The communities of red algae are the most diverse in the rivers of the western part of the Vologda region, where all studied syntaxa are recorded. The plant communities of the association Batrachospermeum gelatinosi are the most common in watercourses of the region. Investigated rhodophyte phytocoenoses are rather sensitive to any changes of environmental conditions indicating the purity of river waters. They can be recommended for conservation purposes.

Published: October 2019

At the moment, the ruderal vegetation of Salavat town (Bashkortostan Republic) (classes Bidentetea tripartitae, Stellarietea mediae and Artemisietea vulgaris) is presented by 20 associations, 3 subassociations, 2 variants, 4 communities (2 derivate and 1 basal) belonging to 7 alliances and 6 orders. High variety of natural and synantrope vegetation is caused by heterogeneity of landscapes within city territory and different degree of anthropogenic impact. A characteristics of synantrope urban vegetation is a presence and increasing of distribution of the monodominant plant communities formed as a result of invasion of aggressive neophytes (derivate communities Bidens frondosa [Bidentetea tripartitae/Stellarietea mediae], Galinsoga parviflora [Stellarietea mediae] and associations Ambrosietum trifidae, Ivaetum xanthiifoliae). Unlike other types of natural and seminatural vegetation, the ruderal vegetation occupies the biggest areas of Salavat town.
