The artical is devoted to the current psychological and pedagogical problem of searching for effective forms of mutual training of students in drawing and painting. The problem requires theoretical justification and practical development. It considers the theoretical foundations of the organization of mutual learning of students, as well as describes a psychological and pedagogical experiment to identify the effectiveness of using in various forms of mutual learning in the process of studying the discipline “Drawing and Painting” by students. The following effective forms of mutual learning are offered: a joint individual form, a joint and consistent form, a joint and interacting form. In addition, the importance of the use of electronic learning tools such as: interactive animation, electronic presentations, interactive technological instructions is indicated. Along with the theoretical justification of the possibilities and necessity of using the above forms of mutual learning of students in the classroom, the article suggests specific practical methods of organizing training assistance by students advisers. As part of providing training assistance by students advisers positive impact of presentations, demonstration of presentations, interactive animation was indicated. During the practical classes they used the developed interactive technological instructions. The effectiveness of the considered publication of forms and methods of mutual learning of students is presented in the description of psychological and pedagogical experiment. The results of this experiment are expressed in diagrams and theoretical conclusions. At the same time, the stages of the experiment are described in detail: diagnostic, ascertaining, forming, control and evaluation, indicating the criteria for analyzing the creative work of students. The main criteria are presented such as: literacy of compositional construction; constructional drawing; a coloristic solution; transmission of tonal relations; creation of an artistic image by picturesque means. The effectiveness of the application of these forms of mutual learning of students is justified in describing the test and evaluation stage of the experiment and the conclusions of psychological and pedagogical research.
Personnel Status and Problems of Teaching Staff in Private Higher Education Institutions in China
Authors: Qiaofang Liu
Published: November 2020

The formation and improvement of the teaching staff in China is currently the main task of accelerating the restructuring of the country’s educational system. Teachers of non-state higher education institutions are important participants, promoters and “drivers” of the development of non-state higher education. But teachers of non-state higher education institutions still have serious problems in the field of teaching methods, scientific research, personal growth, etc. All these have become key factors that limit the long-term development of non-state higher education institutions. The article analyzes the difficulties in formation of the teaching staff taking into account its structure and characterizes its current state. Besides, the article considers the factors influencing the stability and career growth of teachers and suggests the corresponding measures for stabilization and improvement of the teaching staff of the non-state universities from the point of view of the state policy support, adaptation of the system of the universities’ management and teachers’ self-development.

Assessing the Validity of Ultrasound Imaging of Wrist Muscle Moment Arms through an Agar Phantom Experiment and In Vivo Case Study
Authors: Charles Jonathan , Nichols Jennifer A.
Published: November 2020

Joints in the human body utilize torque to create movement, where a force F acts at a distance, r, from a rotation point. In biomechanics, F is generated by muscles acting on the joint, and r is the distance between the joint’s center of rotation (COR) and the muscle line of action. This distance r is known as a geometric moment arm (GMA). Changes in GMAs may be correlated with loss of muscle and hand function in people due to aging, injury, or pathology. To comprehensively evaluate GMAs, efficient and inexpensive methods for measuring them in vivo are needed. Thus, this study explores whether ultrasound is a valid imaging modality for quantifying the GMA of muscles crossing the wrist. An agar-gel phantom was used to determine if distance measurements from 20 ultrasound images of the phantom were accurate compared to a set of four baseline distances. A subsequent in vivo case study explored whether ultrasound could measure GMAs within a human wrist. The capitate bone was defined as the wrist’s COR due to its central location in the joint, and the measured GMA was defined between this COR and the flexor digitorum superficialis (FDS) muscle. Both studies returned data that exhibited low measurement variability over consecutive days and provided reasonable proof that ultrasound can accurately measure wrist GMAs.

Paul Rudolph’s and Carlo Scarpa’s Interaction with the Environment
Authors: Moumne Jordan Elena
Published: November 2020

This paper examines how Paul Rudolph and Carlo Scarpa design buildings in a seemingly harsh environment to connect occupants to that which is around them. It involves the study of Fondazione Quarini Stampalia and Camping Fusina by Scarpa, along with the Umbrella House and the Healy Guest House by Rudolph, analyzing the buildings through methods of site visits, photography, and drawing. Specifically, it analyzes how the architects frame the environment, experiment with view, explore visible connection of the ground, planning for the inevitable flooding that will occur, and creating a feeling of safety for people to positively interact with what is around them. This study determines that while all these methods are important in designing buildings, it is how the architects develop an appreciation of the environment by the occupants that is imperative in designing for the future of Florida. For a more resilient Florida that can handle the environmental pressure being forced on it while also developing a design language that makes Florida’s architecture stand out.
How Start-up Businesses View and Use Accounting in Early Year Operations
Authors: Hutchins Contessa
Published: November 2020

This research analyzes how start-up companies implement accounting in their early operations and if that use of accounting (or lack thereof) has played a role in acquiring funding. Prior research shows that the quality of financial statements positively affects investing efficiency for companies in emerging markets (Chen et al., 2011). In this paper, we evaluate the hypothesis that start-ups using financial statements more extensively receive more outside funding than their counterparts. This was tested with a 27-question survey broken into three sections: demographic, accounting use, and financial information. There were 44 participants. The typical start-up profile is 5-6 years old, employs ten people, and identifies in the technology industry. Approximately 75% of participants reported using financial statements. While mostly viewed positively, some participants feel strongly against using standard accounting practices. Results showed companies who use financial statements more often reported a higher percentage of debt and investment funding received than those who used financial statements less frequently or not at all. In conclusion, accounting helps start-ups communicate higher quality information to investors, thus leading to a better chance of receiving capital investment/debt financing. This sample selection was not chosen randomly and is not a statistical depiction of the entire population.
Effects of the sphragis on male and female genitalia in Acraea (Nymphalidae) butterflies
Authors: Summers Shannon L , Kawahara Akito Y , Carvalho Ana P. S.
Published: November 2020

Male mating plugs have been used in many species to prevent female re-mating and sperm competition. One of the most extreme examples of a mating plug is the sphragis, which is a large, complex and externalized plug found only in butterflies. This structure is found in many species in the genus Acraea (Nymphalidae) and provides an opportunity for investigation of the effects of the sphragis on the morphology of the genitalia, which is poorly understood. This study aims to understand morphological interspecific variation in the genitalia of Acraea butterflies. Using specimens from museum collections, abdomen dissections were conducted on 19 species of Acraea: 9 sphragis bearing and 10 non-sphragis bearing species. Genitalia imaging was performed for easier comparison and analysis and measurements of genitalia structures was done using ImageJ software. Some distinguishing morphological features in the females were found. The most obvious difference is the larger and more externalized copulatory opening in sphragis bearing species, with varying degrees of external projections. Females of the sphragis bearing species also tend to have a shorter ductus (the structure that connects the copulatory opening with the sperm storage organ) than those without the sphragis. These differences may be due to a sexually antagonistic coevolution between the males and females, where the females evolve larger and more difficult to plug copulatory openings and the males attempt to prevent re-mating with the sphragis.
The Living Community Challenge for Environmental and Urban Sustainability
Authors: Krinos Larissa
Published: November 2020

The Living Community Challenge (LCC) is a green certification program that, unlike most certification programs, is geared toward whole neighborhoods as opposed to singular buildings. Unfortunately, no existing communities have achieved Living Community Challenge certification. Still, there are many neighborhoods utilizing the ideals – known as petals – of the LCC in attempts to become more sustainable. The Living Building Challenge (LBC), the parent certification for the LCC, has seen more success than the LCC and will provide further research on the implications of its criterion. This paper will look at the hypothetical variables of the LCC, the communities trying to achieve these variables, and how elements of it could be used in relation to impoverished communities. Through case studies on groups and individuals attempting LCC and LBC certification, specifically Bend, Oregon and the BLOCK Project, the potential of the research becomes evident. This paper seeks to demonstrate how the LCC could be applied specifically in low-income areas in Gainesville, FL without achieving all the requirements of each petal.
Understanding the Browning Reactions in Sweet Basil
Authors: Vieira Annelise , Burrell Samantha , Cho Keun H. , Clark David G.
Published: November 2020

Polyphenol oxidase (PPO) is a well-characterized enzyme that is conserved across plant species and is responsible for catalyzing the rapid polymerization of o-quinones that results in tissue browning. As these oxidation reactions result in significant reductions in food crop commercial viability, nutritional content, and general desirability, an opportunity exists to improve a variety of crops via genetic regulation of PPO expression. The main objective of this project was to clone the DNA sequence of genes encoding PPO. Using mRNA as a template to synthesize DNA, two putative PPO sequences were cloned from Ocimum basilicum and Ocimum americanum, two basil species of commercial relevance. A secondary objective of this project was to insert a cloned PPO sequence into an RNAi vector for the purpose of making transgenic basil plants with reduced PPO expression. A hairpin RNAi construct was successfully developed to reduce the expression of both PPO genes as their DNA sequences were highly homologous. The next step for this project will depend on the development of transformation and regeneration protocols for these species, which have proven to be difficult. Once the RNAi PPO constructs are introduced into basil cells and successfully regenerated into plants, reduced browning of basil leaf tissue when it is wounded or cut is expected.
Effect of Sonication on Plant Stomatal Movement
Authors: Jeevaratnam Suren , Lin Chuwei , Chen Sixue
Published: November 2020

The primary goal of this study was to determine the effect of sonication on stomatal movement. A minor goal was to determine the best time interval at which sonication is the most effective at removing mesophyll cells and enriching guard cells. For this study, abaxial leaf peels of Arabidopsis thaliana were sonicated for 1, 3, 5, and 7-minute intervals at a set amplitude to analyze the removal of mesophyll cells. To juxtapose the leaves and to determine guard cell enrichment, microscopic images were taken prior to and after sonication. Furthermore, to establish that the stomata are alive, neutral red staining was used in conjunct with 40x magnification. It was hypothesized that sonication is an effective method for the removal of mesophyll cells and the enrichment of guard cells. The results of this study suggest that sonication is in fact an effective protocol for guard cell enrichment; however, it is not as effective for guard cell purification. This is due to the presence of mesophyll cells and epidermal layers present after sonication. Previous research dealing with sonication is very prevalent; however, research on sonication dealing with the removal of mesophyll cells in Arabidopsis thaliana is not widely studied. Thus, previous information to support this study could not be attained. Results from the first part of the experiment were then extended to determine how sonication affects stomatal movement. It was determined that in the experimental group, the average stomatal aperture decreased over a two-hour period.
Exploring Autism Disparities Among Latina Girls
Authors: Moreira Daniela N , Angell Amber
Published: November 2020

There is increasing evidence of ethnic and gender disparities in autism spectrum disorder (ASD) identification and receipt of services. Compared to White males, Latino children and girls are both more likely to receive a delayed diagnosis and less likely to receive high-quality services. Little is known, however, about Latina girls with ASD, including how their ‘pathway to a diagnosis’ compares to non-Latina White girls. To address this gap, this collective case study draws upon interviews with four families from two larger qualitative studies investigating ASD disparities. The purpose of this study is to compare the autism diagnosis and services experiences of three Latino families and one non-Latino White family of girls with ASD. Two researchers coded seven interviews using thematic and narrative analysis. The researchers identified three themes: 1) The Latino cases involved extended family members as both barriers and facilitators to the ASD experience, while the non-Latino case had little extended family involvement; 2) The Latino cases involved a tension between specialized ASD knowledge and culturally-influenced stigma around disability; 3) All cases suggest a female ASD phenotype that differs from the traditional ASD presentation. The study concludes with recommendations for improving support for Latino families with girls with ASD.

Posterior Alpha Power During Working Memory Maintenance in Alcohol Use Disorder
Authors: Rilo Natalie Eve
Published: November 2020

Individuals with alcohol use disorder (AUD) display modest neurobehavioral deficits on cognitive tasks such as working memory (WM). Neurophysiology (i.e. posterior alpha power) during the maintenance phase of a WM task was compared. Healthy controls (HC, n=50) and newly abstinent individuals with AUD (n=42) completed a directed attend/ignore WM task. Spectral alpha power was extracted from the posterior portion of the scalp. A mixed linear model compared posterior alpha power controlling for alpha power in a baseline condition between group (HC vs. AUD) and sex (male vs. female). Main effects for group (p=.01) and sex (p=.003) were significant. HC displayed a higher alpha power compared to that of individuals with AUD. Males also presented with higher alpha power compared to women. There was no significant interaction between group and sex. An exploratory analysis to determine a relationship between alpha power and performance on the task was conducted and a differential relationship between groups (p<.001) was found. There was no significant relationship between performance and spectral power for HC, but a negative relationship was found for individuals with AUD. Higher alpha power was associated with decreased accuracy (p=.09). Individuals with AUD display a lower alpha power compared to HC, and this is associated with increased accuracy. Whether this signifies a compensatory mechanism remains a question intended for investigation.

Authors: Bomser Rachel , Gibson Heather J. , Zhang Hongping
Published: November 2020

Since 2007, the University of Florida has hosted summer field-based, sustainability-focused study abroad programs in Australia, New Zealand, and Fiji. The purpose of this study was to examine the impact of these study abroad programs on change of major and subsequent career choice. Program alumni (2007-2019) completed an online questionnaire. N=94 responded to questions about impact on major (yes=1, no=2), career choice (yes=1, no=2), and open-ended responses. Data were analyzed using descriptive statistics, chi square, and content analysis. Five of 94 respondents changed majors and 39/93 reported study abroad influenced their career choice. Content analysis revealed participation influenced: n=14 to pursue a sustainability-focused career, n=8 to work in “a helping-profession”, n=6 to pursue ecotourism, and n=4 to study environmental law. Program participation seems to be influential for some in future career choice, but not major change.
Discrete Event Simulation of a Specialty Outpatient Clinic to Improve Patient Flow
Authors: Mangoni Samantha Lynn , Li Xuanjing
Published: November 2020

The objective of this study was to test the validity and efficacy of discrete-event simulation (DES) in modeling a specialty outpatient clinic, and to apply the model to predict how the clinic could improve their patient flow. Arena software was used to develop this DES model. Real-life model inputs included the time that patients spent in each clinic process, clinic room utilization rate, and physician room schedules. The DES was validated via a comparison between the model’s outputs and raw clinic data, and further validated by clinic leadership. Once validated, the DES was modified to represent different scenarios, such as changes in clinic scheduling and resource usage. Analysis of the models revealed that adding two volunteers to escort patients in the morning and afternoon would decrease the queue time to see a physician by 33.9% and 65.2% respectively. The model results also suggested that there is not enough congestion in the clinic to warrant changingthe clinic scheduling from fixed room scheduling to un-assigned room scheduling.  The results of the this study support the usability of DES in the modeling and analysis ofspecialty outpatient clinics to provide decision support.
Drying of Algae: Analysis of Oedogonium Dehydration Kinetics
Authors: Bjorndal Lars Cronje , Wilkie Ann C.
Published: November 2020

Algae cultivation has multiple potential applications including biofuel production, wastewater treatment, and carbon capture.  However, dewatering and dehydration remain a challenge for commercialization.  Research has focused mainly on microalgae, but filamentous algae have recently gained attention due to their larger size and thus relative ease of harvesting.  The drying mechanics of filamentous algae has yet to be fully understood and optimized.  This study investigated the drying behavior of the filamentous algae Oedogonium at 50℃, 60℃ and 70℃.  The moisture content of triplicate samples of microalgae and Oedogonium (intact filaments, fractured filaments, and aggregated forms) was measured during drying. Intact Oedogonium filaments were fractured using a food blender. Intact Oedogonium had an average shorter falling rate phase and higher diffusivity then microalgae at all temperatures, resulting in a 15%, 8.3%, and 11% faster total average drying time at 50℃, 60℃ and 70℃ respectively. Fractured Oedogonium further had a shorter falling rate phase than intact Oedogonium at 50℃ and 60℃ where its average total drying time was respectively 18% and 9% faster, but the effect of the fracturing treatment reduced with increasing temperature and became negligible at 70℃. Thus, Oedogonium appears to dry more effectively than microalgae, and fracturing Oedogonium results in faster dehydration at lower temperatures. These findings could help optimize industrial drying and assist in the commercialization of algae cultivation.
Congestion pricing optimization for shared transport
Authors: Osuna Andres , Liu Hongcheng
Published: November 2020

This project includes the analysis of transportation systems by mathematically modeling the collective decision making of drivers via Nash games. This paper considers two types of traffic pricing models which capture the implication of pricing on shared transport. Both models follow a game theoretic framework and capture the perspective of private shared transport companies that aim to increase their profit while improving social welfare or users’ time cost. The first model was established for users who vary their routing choices but not their transportation modes when the demand levels are fixed. The second model is more appropriate for companies with users who optimize both their routing and choice of transportation based on the pricing policy of the system where demands are elastic. Two pricing policies can be determined by convex formulations of optimal system traffic assignment problems on simple networks with different origins and destinations. The models also show how pricing affects road users’ decisions under different parameter settings. The numerical results confirmed formulation feasibility and gave insight on how the company can have an impact on both their revenue and time cost by modifying their pricing scheme.
House Beautiful, Climate Control Project 1949-1953
Authors: Muldowney Carolyn , Baweja Vandana
Published: November 2020

The postwar transition to suburbia inaugurated a trend in which most American builders opted to clear the land and build standardized houses without any regard for the site conditions and local climate. Elizabeth Gordon (1906–2000) was the editor of House Beautiful a popular design magazine. She launched the Climate Control Project (1949–1953) to offer the homebuilder guidance on constructing houses suited for the local climate using design principles of orientation, sun control, site planning, and ventilation. Gordon was a strong critic of the International Style that developed in Europe in the interwar period and came to America after the war. This paper will examine the techniques prescribed by the Climate Control Project and draw conclusions about the ideal postwar house promoted by the magazine. Using the Climate Control project, House Beautiful advanced strategies for physiological comfort and efficient utilization of space as central objectives for its readers. By analyzing the articles published throughout the project's duration, this study concludes that the Climate Control Project promoted the idea of a regional American home as the ideal postwar home – as an alternative to the prefabricated mass-produced suburban homes during this time period and the International Style.

Hip Hop is a cultural phenomenon that is constantly evolving and has made a worldwide impact in a short time. While it continues to change Hip Hop at its core remains the same. Victor Quijada artistic director of the Rubberband Dance company posed the question of “What more could Hip Hop be”. With those words in mind the focus of my research is to examine the movement and concepts/ideologies of the breakdancing subculture of Hip Hop; to create a fusion with contemporary dance. As such a brand-new system of movement with its own concepts and life could be created. The dance world is continuously shifting, and different skill sets, as well as ideologies, have been valued at different times and places. This exploration will challenge the mainstream ideals of what is currently considered “technique” and “foundation”
Influence of Autonomous Vehicles on Insurers and Ride-Hailing Services
Authors: Alfonzo Carlos Eduardo
Published: November 2020

Autonomous vehicles have captured the public’s imagination for what they could do to change the way people move from one place to another. Relative newcomers to the auto industry, such as Tesla, Alphabet, and Uber, have been developing software seeking to power fully autonomous vehicles. The implication is that there would be no need for a driver. Driverless vehicles pose a number of issues and opportunities for transportation companies and their affiliate industries such as car insurance companies. Traditional automakers such as Ford and BMW are partnering with both other automakers and technology companies in order to engage synergies and achieve complete automation before their competitors. With this competition underway, there are sectors in the economy whose current business models would be disrupted by autonomous vehicles. One of these is the car insurance industry, which depends on sharing risk with policy holders. This paper delves into the topic of how insurance companies would be affected by a change in this risk-sharing relationship with policy holders. Furthermore, this paper also examines the current status of the ride-hailing industry and how the main service providers are aiming to benefit from autonomous driving technology.
Understanding the Victorian Unfeminine
Authors: Calderazzo Hannah
Published: November 2020

My project traces concepts of the unfeminine from Wilkie Collins’s sensation novel The Woman in White (1860) to Victoria Cross’s New Woman fiction in Six Chapters of a Man’s Life (1903). Both texts feature female characters who defy Victorian standards of femininity. Marian Halcombe of The Woman in White is regarded as “ugly,” with “almost a moustache,” yet Walter Hartright (the narrator) admits to the “rare beauty of her form” when he meets her. Marian is also extremely intelligent, using her wits and courage to help protect her half-sister. The unnamed male narrator of “Theodora” from Six Chapters of a Man’s Life meets a similar female character (Theodora), who also has a mustache and looks “like a young fellow of nineteen.” Nonetheless, Theodora is highly educated, even advocating for sex for sex’s sake. Though Theodora is unconventional in her appearance and character, the narrator grows more attracted to her. In defiance of their conventionally unfeminine physical and mental characteristics, both women are regarded as striking by their male narrators. I examine these characters’ unfeminine appearance and heightened intelligence in combination with their radical desirability, suggesting that parallels between Marian and Theodora establish a firm connection between these two Victorian genres as they construct concepts of attraction and the “unfeminine” woman.
Word Learning in Two Modalities
Authors: McHugh Emily Anne
Published: November 2020

A majority of research on language development has focused on examining spoken word learning and its role in the development of language, but there has been more limited research investigating the role of gesture and signed words in language development. This study investigated the impact of modality of word presentation on the learning of an associated meaning, the impact of modality of meaning presentation on the learning of an associated word, as well as the impact of crossing modalities on the speed and accuracy of learned associations. Participants viewed short videos of a person saying a non-word or making a sign paired with either a picture or a written definition.  Outcome variables were accuracy and response times for recall of meanings. 

          The analysis of accuracy revealed a significant interaction between presentation modality and meaning modality. Accuracy in the nonword-picture condition was at ceiling and thus, significantly greater than accuracy in the nonword-definition condition and nonsign-picture condition. Analysis of response times found the main effect of meaning format to be statistically significant. Participants were significantly slower when meaning was presented as a definition compared to when it was presented as a picture. These results suggest that meaning associations with novel signs are learned equally fast and accurate as those associated with novel words. Additionally, they suggest that people recall imageable meanings faster than definitions. Finally, results also indicate that typically functioning adults maintain a robust ability for learning word-picture associations likely developed in childhood.

On the other hand, as a minority, theirexistence needs to be explored. This study aims to describe the forms of tolerance accepted by non-Muslimstudents, describe the impact of tolerance on their daily lives, and describe the power relations between lecturersand non-Muslim students. This research took place from May to October 2019 and involved five non-Muslimstudents, two religious lecturers and a campus authority representative. This study uses a qualitative approachwith ethnographic types, and uses three methods of data collection, namely observation (fieldnotes), interviews(open-ended questions) and Focus Group Discussion (FGD) which are analyzed using reading, describing, andclassifying techniques. The results of this study indicate that there are several forms of tolerance accepted bynon-Muslim students, namely; the option to not take the semester exams and take grades from the church, thefreedom to work on assignments according to their perspectives and beliefs, and given the freedom to participatein discussions. Apart from the power of lecturers to carry out Islamization, religious lecturers carry out theirduties professionally. The effort of Islamization is carried out by providing a correct explanation of Islamaccompanied by evidence of its truth, not in striking and coercive ways.

Published: November 2020

Realistic mathematics learning is a teaching approach that starts from "real" things for students. Fraction problems are often found in daily life and are felt difficult by most students in SD.N.Kp.Baroh Langsa so that student learning outcomes are still relatively low. The purpose of this research is to find out whether the use of Realistic Mathematics Learning can improve the learning outcomes of fourth-grade students of Semester II SD.N.Kp.Baroh Langsa. The approach used in this study is a qualitative approach and the type of research is classroom action research consisting of 2 cycles. The research subjects are grade IV students of SD.N.Kp.Baroh Langsa, amounting to 33 students. Data analysis used a comparative descriptive analysis technique by comparing conditions in cycle I and cycle II. Based on the results of research at the end of the second cycle it is known that there has been an increase in the class average of 29.16% from an average ofthe first cycle test of only 58.18 up to 75.15. Then completeness of student learning also increased by 87.50% from the first cycle that has been completed only 16 students to 30 students. So that most of the fourth-grade students of SD.N.Kp.Baroh Langsa experienced an increase in learning outcomes in fractional material. Thus it can be concluded that the use of realistic mathematics learning in fraction material can improve the learning outcomes of fourth-grade students of the second semester of SD.N.Kp.Baroh Langsa.
Comparing atmospheric trace element accumulation of three moss species
Authors: Tien Doan Phan Thao , Khiem Le Hong , Trinh Trinh Thi Thu , Frontasyeva Marina Vladimir , Sang Nguyen Thi Minh , Nguyen Son An
Published: November 2020

Introduction: The intention of Vietnam to participate in the European-Asian Moss Survey in the framework of The United Nations Economic Commission for Europe - International Cooperative Programme on effects of air pollution on natural vegetation and crops (UNECE ICP Vegetation) necessitates choosing appropriate moss species that grow in the tropical and subtropical climate of Vietnam. The three selected moss species, divided into phytogeographical elements, were as follows: Leucobryum (aduncum, albidum), Hypnum commutatum and Barbula indica.

Methods: The present study focuses on Central Vietnam where 18 samples of the three above moss species were collected in the vicinity of Dalat and Hue cities. Elements in the moss samples were detected by neutron activation analysis (NAA) at the IBR-2 reactor of the Division of Neutron Activation Analysis, Frank Laboratory of Neutron Physics, Joint Institute for Nuclear Research in Dubna, Russia.

Results: The analytical results for twenty-three trace elements, which were used to study elemental accumulation abilities of the three moss species in the air, were Na, Mg, Al, Cl, K, Ca, Ti, V, Mn, Fe, Co, Zn, As, Br, Rb, Sr, Sb, I, Cs, Ba, La, Th, and U. The accumulation abilities were found to decrease in the following order: Leucobryum > Hypnum > Barbula. However, Leucobryum, because of its short stem, was not judged to be a suitable candidate for biomonitoring.

Conclusion: The element accumulation abilities of Hypnum moss were better than those for Barbula, but both were comparable and could be used as indicators for air deposition monitoring; however, Hypnum was not widely present in Vietnam. Thus, Barbula indica moss could be used for performance of atmospheric deposition monitoring in Vietnam.
Government procurement clause in EVFTA and implications for Vietnam
Authors: Nguyen Hoang Tien , Do Vuong Hoang
Published: November 2020

EVFTA is one of the newest endeavors of Vietnam regarding the international integration process, which is anticipated to be beneficial for Vietnam in many aspects across industries. The government procurement sector does not stay out of this influence. This article mainly aims to explore the government procurement sector of Vietnam, the performance of the government regarding managing this market and how it will be affected and reformed by EVFTA. More importantly, by examining the significant factors that may have an impact on the EVFTA's implementation from Vietnam's perspective, the article attempts to assess the compatibility of the current situation of Vietnam with the fundamental conditions to conduct public procurement regulations of EVFTA efficiently. The article collects, summarizes, and analyzes the secondary data from trustworthy sources like the Vietnam General Statistics Office, the ranking table of the International Telecommunication Union, the official annual report of state departments of Vietnam, and other documents like journal articles, research papers,etc. Another methodology employed in the research is the in-depth interviews with professional experts who have been working for several years in the international integration field. the article discovers that Vietnam is capable of implementing EVFTA's chapter 9 efficiently but with more careful preparation. The article also points out that despite of having a strong mindset of globalization, Vietnam's public expenditures are still loosely covered by laws, which leads to irrational allocation on national budget. A number of implications are suggested to localize the EVFTA's regulations and recommendations are made to apply modern technologies to improve the procurement system, especially on the capacity of government on managing the government procurement sector. The authors hope to help state authorities to have a broader look and improve the sector as well as embrace the opportunities from EVFTA regarding government procurement sector.

The analysis of the design and technological features of the tail boom (ТB) of a helicopter made of polymer composite materials (PCM) is carried out.Three structural and technological concepts are distinguished - semi-monocoque (reinforced metal structure), monocoque (three-layer structure) and mesh-type structure. The high weight and economic efficiency of mesh structures is shown, which allows them to be used in aerospace engineering. The physicomechanical characteristics of the network structures are estimated and their uniqueness is shown. The use of mesh structures can reduce the weight of the product by a factor of two or more.The stress-strain state (SSS) of the proposed tail boom design is determined. The analysis of methods for calculating the characteristics of the total SSS of conical mesh shells is carried out. The design of the tail boom is presented, the design diagram of the tail boom of the transport category rotorcraft is developed. A finite element model was created using the Siemens NX 7.5 system. The calculation of the stress-strain state (SSS) of the HC of the helicopter was carried out on the basis of the developed structural scheme using the Advanced Simulation module of the Siemens NX 7.5 system. The main zones of probable fatigue failure of tail booms are determined. Finite Element Analysis (FEA) provides a theoretical basis for design decisions.Shown is the effect of the type of technological process selected for the production of the tail boom on the strength of the HB structure. The stability of the characteristics of the PCM tail boom largely depends on the extent to which its design is suitable for the use of mechanized and automated production processes.A method for the manufacture of a helicopter tail boom from PCM by the automated winding method is proposed. A variant of computer modeling of the tail boom of a mesh structure made of PCM is shown.The automated winding technology can be recommended for implementation in the design of the composite tail boom of the Mi-2 and Mi-8 helicopters.

Authentication is one of the significant issues in the era of information system. Among other things, human face recognition is one of known techniques which can be used for user authentication. As an important branch of biometric verification, HFR (Human Face Recognition) has been widely used in many applications, such as video monitoring/surveillance system, human-computer interaction, door access control system and network security. Face Recognition begins with extracting the coordinates of features such as width of mouth, width of eyes, pupil, and compare the result with the measurements stored in the database and return the closest record (facial metrics). Nowadays, there are a lot of face recognition techniques and algorithms found and developed around the world. This system uses this face detection for attendance of students in a classroom. The traditional method of attendance requires more physical effort. It can be a little time consuming. Through this system, attendance can be handled without human intervention. Not only the attendance on a daily basis but a small report required to track student activity (total number of lectures attended and pertaining percentages can be displayed).
