OBTENÇÃO E CARACTERIZAÇÃO DE BIOMASSA DE BANANA VERDE

A biomassa de banana verde (BBV) e um produto obtido do cozimento das bananas verdes, processado na forma de pure e que pode ser adicionado no enriquecimento de diversos alimentos por ser insipida e inodora, nao promovendo alteracao no sabor e aroma, alem de possuir amido resistente. Objetivou-se nesse estudo obter biomassa de banana verde e avaliar a influencia do armazenamento congelado e refrigerado, com e sem a adicao de acido citrico, sob a cor, pH, acidez titulavel, atividade de agua (Aa) e perfil de textura. O experimento foi conduzido com tres repeticoes, no delineamento inteiramente casualizados (DIC). Verificou-se uma reducao da variavel a* apos 10 dias de armazenamento e um significativo escurecimento e reducao da variavel b* apos 20 dias de armazenamento. Resiliencia, mastigabilidade e elasticidade foram menores para as biomassas armazenadas refrigeradas. A atividade de agua nao foi influenciada pelos tratamentos. A adicao de acido citrico nao promoveu manutencao da luminosidade (L*) e da variavel a* ao longo do tempo de armazenamento. Os tratamentos mantidos sob congelamento apresentaram menor variacao dos parâmetros fisico-quimicos, sendo o mais indicado para armazenamento da biomassa de banana verde, independente da adicao de acido citrico.
Preferential Flow Pathways and Their Capacity to Transport Isoproturon in a Structured Clay Soil

A field experiment was established to monitor preferential flow pathways and their capacity to transport isoproturon in a heavy clay soil. A hydrologically defined plot of 600 m 2 at a field site on the Oxford University Farm at Wytham was created with integral flow monitoring and sampling devices. Data are presented from two flow events which occurred in April and May 1994. The highest concentrations of isoproturon (130 μg litre -1 ) were observed in the drainage system. The vast majority of the 0.7% of applied pesticide that left the plot was via the drainage system (75-90%) with lateral subsurface flow accounting for a smaller proportion (max 23%). Whilst high pesticide concentrations could be found in overland-flow water, the volumes of water moved by this route were small (max 3%). Less water was estimated to have left the field in response to rainfall than in the previous year. This was attributed to decay of the mole drain system. Consequently the amount of applied pesticide lost in runoff (0.7%) was less than that estimated for the first year (1.5%). The work has shown that, even when a farmer follows best practice in the application of a herbicide to a winter cereal in a drained clay field, high concentrations of the herbicide (relative to the EC drinking water limit) will contaminate surrounding watercourses.
Phase Composition and Molecular Mobility in Nylon 6 Fibers as Studied by Proton NMR Transverse Magnetization Relaxation

The phase composition and molecular mobility of Nylon 6 fibers has been studied using 1 H solid-state NMR transverse magnetization relaxation (T 2 relaxation) spectroscopy. One of the objectives of this work is to determine the usefulness of the NMR relaxation method to accurately determine the crystallinity of Nylon 6 fibers. The NMR relaxation results have been interpreted using a three-phase model, which is proposed on the basis of distinct differences in chain mobility in the crystalline phase, the semi-rigid crystal-amorphous interface, and the soft amorphous phase. In order to obtain accurate data on the phase composition, the effects of absorbed water and annealing of fibers at elevated temperatures were studied in detail. It was shown that water mainly plasticizes the soft fraction of the amorphous phase. Changes in the phase composition and molecular mobility caused by fiber annealing at elevated temperatures were studied with real-time NMR T 2 relaxation experiments. The most pronounced annealing effects (changes in the phase composition) were observed for undrawn fibers with low molecular orientation. Annealing slows down for fibers produced at larger winding speed and especially those with a high draw ratio, are found to affect the phase composition and molecular mobility in different phases. It was shown that the present NMR relaxation method provides a fast and accurate technique to analyze the phase composition of Nylon 6 fibers. The amount of rigid phase determined from NMR is in good agreement with the crystallinity of the fiber obtained using the traditional method for Nylon 6 fibers, which involves a combination of density measurement, wide-angle X-ray diffraction and 13 C NMR spectroscopy. Hence, the present NMR relaxation method greatly simplifies measurement of crystallinity in Nylon 6 fibers.
¿Amas de casa o empresarias? Los negocios de venta en los mercados municipales

The supply trade that was carried out in the municipal markets connected the urban world with the rural one. The work of women, as peasants and as sellers in the market, was vital to its operation. Most of these women do not appear, however, in official sources, as is generally the case with the work of married women, which is the most statistically underestimated, so alternative sources that recognize it should be sought. In this article, the Market of the Independence of Terrassa is studied during the first quarter of the 20th century through the “Auctions and place of sale permits of the Market”. This source, together with the crossing of other primary sources, allows us to know the composition of the homes of the peasant-salesmen, their age, marital status, number of children and the profession of the head of the family. These factors are analysed in relation to the job offer of married women and the role of these small businesswomen in urban markets is reconstructed.
The Effects of Agility Training to Football Players of Secondary Schools in Ranau

The purpose of this study is to identify the effects of agility training to football players of secondary schools in Ranau. A total of 20 football players were chosen to participate in this study using non-random sampling method. The researcher adopted the experimental design that uses a comparative design between the effects before and after training in 6 weeks. The football players were divided into two groups, the control group and treatment group. The agility level was assessed through Short Dribbling Test. The obtained data were analysed using Independent T-test by SPSS version 23.0. The findings show that there is significant difference in the agility level of the control group and experimental group players in the post-test. In overall, the agility training had a positive impact on the agility performance of the players. Developing agility in football training enhancing the skills to stop on a dime, change direction and keep moving in one fluid motion. Introduction Football is considered as the number one sport in Malaysia and rest of the world based on television audiences, compared to other sporting events viewed (Karim & Nadzalan, 2017; Karim, 2016). Football is considered a high demand game as the players are subjected to numerous actions that require overall strength and power, speed, agility, balance, stability, flexibility and adequate endurance level, thus making the conditioning of players a complex process (Jovanovic, Sporis, Omrcen & Fiorentini, 2011). According to Paul, Gabbett & Nassis (2016), team sports are characterized as being intermittent in nature, whereby players are required to frequently transition between brief bouts of high-intensity running and long periods of low-intensity activity. In addition, players need to perform movements such as tackling, blocking, jumping and integrate directional changes and other technical skills. Agility is one of the important features of team football players. There is a growing interest in the factors that influence agility performance and appropriate test protocols and strategies to evaluate and improve this quality (Salmela, 2018). Agility is the ability of the player to execute fast whole-body motion with velocity or direction International Journal of Academic Research in Progressive Education and

Innate trypanolytic factors in triatomine hemolymph against Trypanosoma rangeli and T. cruzi: a comparative study in eight Chagas disease vectors

There is limited information about the innate immunity of triatomines against Trypanosoma rangeli, an infectious, non-pathogenic human parasite, and T. cruzi, the causative agent of Chagas’ disease. This study aimed at addressing this gap by studying the in vitro trypanolytic hemolymph activity from insects not infected by T. rangeli or T. cruzi. Eight triatomine species were examined including Rhodnius prolixus, R. robustus, R. colombiensis, R. pallescens, R. pictipes, Triatoma dimidiata, T. maculata, and Panstrongylus geniculatus. The hemolymph of R. prolixus and R. robustus laboratory colonies demonstrated strong trypanolytic activity during the first 14 hours of parasite incubation with 81% lysis for the T. rangeli C genotype, 90% for the E genotype, 95% for T. cruzi discrete taxonomic unit (DTU) TcII, 94% for TcV, 96% for TcVI, 94% for Tcbat, and 90% for Tcmarinkellei. No lysis activity was detected 14 or 24 hours after parasite incubation with the hemolymph of insects from R. pictipes R. pallescens, P. geniculatus, and T. maculata colonies. Identical results (absence of lysis) were observed using hemolymph from R. colombiensis and T. dimidiata laboratory colonies and specimens captured in sylvatic environments. The hemolymph lytic activity against recently obtained cultures (95% decrease in live parasite count) and long-term T. cruzi TcII ones (96% decrease) was similar. Lytic activity was similar in hemolymph from R. prolixus nymphs, males and females and insects fed on chicken or mouse blood. This is the first comparative study of the trypanolytic activity of hemolymph from different triatomine species against T. rangeli and T. cruzi genotypes. Although the chemical structures of such lysis factors and the mechanisms determining their expression have not been fully determined, their identification furthers our understanding of triatomines’ innate immunity and their role in Trypanosoma transmission.
Detection and Classification of Obstacles Using a 2D LiDAR Sensor

Detecting and mapping obstacles is an important component in mobile robots. In this paper, we use only an economic 2D Light Detection and Ranging (LiDAR) sensor to make a 3D map of the scene, classifying the scanned data into ground, obstacles and potholes. To do this, the points from the LiDAR are clustered in segments, and then they are classified depending of their height. The method successfully classifies in low dynamic structured environments, and generates compact 3D map that represents the scene with a few points. Keywords–Mobile robots; LiDAR; 3D map; Low-cost.
Embodied Conversational Agent for Emotional Recognition Training

Avatars are known in the world of video games, where heroes with specific characters, attributes and powers are assigned to players. However, avatars are evolving and reaching domains like companions, assistants and tutors. These avatars now use speech, facial expression, body language or text to interact with humans. When we say interaction, we say emotional expression and empathy. Avatars are still short in the emotional and empathic world; they cannot express nor share emotions. In this paper, we research the emotional avatar world, and we present the Anthropomorphic Chatbot for Emotion Recognition (ACER), an empathic friend companion designed for children. The goal of ACER is to teach children about emotions by expressing them through facial expressions and body language while texting through a chat. An experiment was held to test the avatar effect. Qualitative and quantitative results show users positive emotions tending towards having a chat with ACER with facial and body expressions instead of only ACERs chatbot. Keywords–HCI; ECA; Conversational agent; Avatar; Emotions.
A Digital Tabletop Tool for Teacher-Student Supervision to Support Student Learning

- Effective integration of technology into teaching and learning is becoming an essential competency for teachers. General classroom lectures are important for understanding the course material, but providing other opportunities like well-structured individual or group supervision sessions for students is indispensable. This will ensure the full mastery of the subject matter and expand the scope of learning experiences. Following a pilot demonstration of 15 students and 3 supervisors, interviews were conducted and the feedback showed the benefits of group supervision for these students. Students noted many positive benefits in support of a collaborative learning environment using a digital platform, while supervisors followed suit in the same perspective. This article, therfefore, describes the use of a digital tabletop board as a learning platform to facilitate individual/group supervision of students. After establishing the design requirements, we proceeded with prototyping, providing a series of sketches illustrating how users might progress through a task using the product under development and, lastly, the finished product with two major functionalities: notes taking and recording during a supervision session. The prototype was tested and analysed. The users indicated that the recording would help playback the supervision session. Also, in terms of usability, the interface was perceived as not different from that of the desktop paradigm, hence, user-friendly. Also, in terms of usability, the interface was perceived as not different from that of the desktop paradigm, hence, user-friendly. Teachers, on the other hand, noted the website created will provide notes or audio record for the students and even serves as announcement platform from the supervisors to the students on the class schedule. This would facilitate the achievement of course objectives and would enhance learning.
Reaction modeling of the multistep synthesis of polyamic acid from pyromellitic dianhydride and oxydianiline

A mathematical model has been developed for studying the multistep synthesis of polyamic acid from pyromellitic dianhydride and oxydianiline. This synthesis process consists of two consecutive semibatch polymerization steps : prepolymerizing and finishing. Using a diffusive mixing theory, the model combines the mixing effect with the chemical kinetics to give a quantitative description of (1) the wide molecular weight distribution of the resulting polymer and (2) the drop of weight-average molecular weight during the holdup. The modeling results have been compared with actual process observations, and excellent agreement has been obtained.
Localization of Y Luminescence at Glide Dislocations in Cadmium Telluride

We demonstrate unambiguously that the well-known defect-related Y luminescence band at 1.476 eV in CdTe originates from the polar Te(g) glide dislocation segments. Crystallographically defined glide dislocation arrangements produced by local plastic deformation on (111)Te surfaces using Vickers microindentation were characterized by temperature-dependent cathodoluminescence (CL) microscopy as well as CL and PL spectroscopy. The identification of the Te(g) dislocation was obtained by determining the surface polarity applying X-ray diffraction and subsequently revealing the volume glide geometry observed by CL imaging after stepwise depth-etching of the (111) sample surface. From the spectral and recombination-kinetic properties of the dislocation-bound Y luminescence the model of radiative decay of dislocation-related excitons is supported. Particularly, we may conclude that they are bound to energy levels in the fundamental gap localized at the 90° Te(g) partial dislocations.
Synthesis and Characterization of 3-Difluoroaminomethyl-3-methyl Oxetane and its Homopolymer

3-Difluoroaminomethyl-3-methyl oxetane (DFAMO) was synthesized via the process of bromination, cyclization, ammonification, amino protection and fluorination with a total yield of 43% and GC purity of 96%. DFAMO was characterized by 1H, 19F, 13C nuclear magnetic resonance (NMR), fourier transform infra red (FTIR) and element analysis. The homopolymer of 3-difluoroaminomethyl-3-methyloxetane (PDFAMO), considered as energetic binder to be used in solid propellants and polymer bonded explosives, with a number-average molecular weight (Mn) about 3000 was synthesized via cationic ring-opening polymerization using boron trifluoride etherate (BTFE) as Lewis acid catalyst, 1,4-butanediol (BDO) as initiator and 1,2-dichloroethane (DCE) as aprotic solvent. The effects of BTFE/BDO feeding molar ratio and temperature of the polymerization reaction were discussed. The structure of PDFAMO was characterized by 1H and 19F NMR.
A Survey on Attribute-Based Encryption Technique for Scalable Data Sharing in Cloud Storage

: Cloud computing provides the flexible architecture to share the applications as well as the other network resources. Cloud storage enables networked online storage. Key management and key sharing plays the main role in the data sharing concept of cloud computing. While cloud computing brings new and challenging security threats to the outsourced data. Hence data owner does not have any control to ensure data security in host data centers. In this paper, Cipher text policy attribute-based encryption (CP-ABE) is introduced with Key aggregate cryptosystem a promising cryptographic solution to this issue. It enables data owners to define their own access policies over user attributes and enforce the policies on the data to be distributed and Attribute policies, Cipher text policies are being aggregated. This effectively eliminates the need to rely on the data storage server for preventing unauthorized data access and integrity. Adding User revocation model enables removing access to suspicious users and Intrusion detection system to alert the owner during defined attacks noticed.
Leveraging Machine Learning and Natural Language Processing for Monitoring E-health Publications

—E-health is a rapidly developing field governed by national and international guidelines. These guidelines are often generic, making it problematic to monitor the development of the field with regards to the expected directions. To address this shortcoming, we present a data analytics pipeline for continuous monitoring of e-health publications in Norway with regards to the national e-health strategy. The pipeline contains PubMed data import module, machine learning, natural language processing modules and a visualization component. The potential of the proposed approach is illustrated by identifying publication trends in Norway for the last ten years. These trends show how well focus areas of the Norwegian e-health strategy are represented in scientific publications. The pipeline is customizable and can be extended to support other countries, e-health strategies and publication channels.
Towards Context Adaptation in Ubiquitous Applications

— Ubiquitous computing is considered one of the most impactful scientific achievements in the last decade. This conception created tremendous revolution in the end-user interactions through the concept of context-awareness. Ubiquitous computing offers a new opportunity to redesign the pattern of conventional solutions where it can easily tailor its processes upon existing contextual situations. Several theoretical architectures have been developed to enable context-awareness computing in pervasive settings. In order to exceed the limits of these related works, we will make a comparative study of these architectures and we will propose our solution. The objective of this article is to propose an adaptation architecture which aims to design and validate a contextual model for ubiquitous systems in order to offer services adapted to the preferences of the user.
FatCombat: A Health Video Game for Education and Promotion of the Recommended Fat Intake among Children

—Overweight and obesity are frequently assumed to be the result of an energy imbalance caused by an excess in calories and fat intake. To help children learn about the different types of fat and their intake recommendations, we developed the health video game FatCombat (FC). In this game, players go inside the bodies of children to help them eat healthily by respecting fat intake recommendations. As a result of their actions, the heart can stay healthy and generate a constant ﬂow of blood to the children’s bodies. FC is based on knowledge of fat intake and integrates a set of behavior change techniques related to cognitive and behavioral theories used in children’s health interventions. In this paper, we describe the design process for FC and report the results of a pilot study to evaluate the effect of FC on the knowledge children have of fat and to evaluate the user experience of FC players. Players of FC improved their knowledge of fats and the game provided high levels enjoyment.
Anisotropy of needle cokes.

The anisotropic properties of several lump needle cokes were studied by means of a X-ray diffractometer, a dilatometer, and a reflected microscope in order to evaluate the anisotropic factors of the needle cokes and to discuss the relations among them. Among them several relations were found, which were well understood on the basis of the structure of the uniaxial arrangement of the crystallites. The change in these factors upon heat treatment was also investigated in order to find how these factors depended on the crystal-growth of the needle coke. Some anisotropic properties of the extruded sample were compared with those of the filler coke, which were observed in a lump shape. The results indicate that the extruded sample had its anisotropic properties considerably lowered. The structure and crystal-growth of the needle cokes are discussed based on these observations.
Comparative Study of Socio-Ideological Practices in English Textbooks in Pakistani Context

pISSN: 2521-2982 The present study is an effort to examine and compare the way socio-ideological practices are projected in the Oxford English Textbook Grade 5 and the English Textbook 5 published by the Punjab (Pakistan) Textbook Board (PTB) prescribed for the government, semi-government and private schools of the Punjab province. The content analysis was employed to find out the percentages of categories and subcategories of reading passages and exercises of the prescribed English textbooks. Socio-Ideological statements were analyzed through the representation of patriotic values and gender roles in the context of local and foreign EFL textbooks. The research findings and results make it visible from the current instructional materials or prescribed English textbooks that the Oxford English textbook is superficial and shallow with respect to its treatment of the target (Pakistani) culture. The textbook is therefore inadequate to the task of teaching and transmitting socio-ideological practices in the deeper sense. Contrary to it, the PTB English textbook offers a limited ground for learning English at length. eISSN: 2707-4587 LISSN: 2521-2982
