Abstract:
This article focuses on the future applications and challenges of nanotube-enhanced composites. In spite of their well-known strength and stiffness, nanotubes have proved incredibly difficult to harness, especially in composites. Researchers have eventually found ways to compatibilize nanotubes by attaching molecules to the nanotube surface. Some formulators compatibilize nanotubes for infusion processes, which pump resin into reinforcing fiber preforms. Electric hybrid car designer Velozzi is working with Bayer Materials Science LLC, a subsidiary of Germany’s Bayer AG, to use nanotube-based composites in its high-performance electric Supercar and its more affordable plug-in hybrid Solo. Lockheed Martin is investigating a complete range of applications for carbon nanotubes in both materials and electronics. The company wants to incorporate nanotubes into its established production methods. Nanotubes improve resistance to impact, fatigue, and microcracking, all properties related to resins. The result is a much stronger and more durable composite.

Abstract:
Projeto de Graduação apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Licenciado em Fisioterapia
Objetivo: Verificar se os reforços positivos promovem uma alteração no alongamento dos isquiotibiais e coluna lombar, incentivando assim a utilização destes na prática clínica. Métodos: É um estudo clínico experimental transversal, realizado com 48 participantes saudáveis (21.19 ± 1.44 anos de idade), distribuídos aleatoriamente por dois grupos: controlo e experimental. Todos os participantes realizaram o teste Sit and Reach duas vezes; No grupo experimental, no segundo teste, foram aplicados três reforços positivos. Resultados: No grupo controlo, entre o primeiro e o segundo alongamento, não se verificaram diferenças significativas. Já no grupo experimental, após ser fornecido o reforço positivo, observaram-se diferenças significativas em todos os grupos, tanto na totalidade da amostra (p < 0.001) como analisando por género (p = 0.003 no masculino; p = 0.002 no feminino), encontraram-se também diferenças significativas em quem pratica desporto (p = 0.018) e em quem não pratica desporto (p < 0.001). Conclusão: Observaram-se diferenças significativas quando o alongamento foi realizado na presença de reforços positivos, promovendo um aumento, independentemente do género e de ser praticante de actividade física. Objective: Verify if the positive reinforcements promotes a change in the stretching of the hamstrings and the low back, thus encouraging its use in clinical practice. Methods: It is a clinical study, performed with 48 healthy participants (mean age 21.19 ± 1.44 years), randomly assigned to one of two groups: control or experimental. Every participant performed the Sit and Reach test two times. The experimental group was given 3 positive reinforcements in the second test. Results: In the control group there were no statistically significant differences between the first and second stretches. In the experimental group, after positive reinforcement, there were significant differences in all groups, analyzing both in the total sample (p < 0.001) and by gender (p = 0.003 male; p = 0.002 female). There were also significant differences between those who practice sport (p = 0.018) and those who do not practice sport (p < 0.001). Conclusion: Significative diferences were observed when stretch was performed with positive reinforcements, promoting an increase in flexibility, independently of the gender or sport's practice.

Abstract:
Negative reinforcement can be a powerful tool for behavior analysts, yet it is often overlooked as a treatment method. Pryor (1999) outlines a method for approaching a "timid" animal using a combination of negative reinforcement and positive reinforcement. When the animal stands still, the human operates a clicker, and then retreats from the animal. Gradually, the human moves closer to the animal through the clicking and retreating shaping process. Once the human is standing close enough, food may be offered as a positive reinforcer, and the negative reinforcer is canceled out. The purpose of this study was to experimentally demonstrate the click-retreat technique with cows. A multiple-baseline design across subjects was used to test this technique. Results show that the click and retreat technique was effective. Results are discussed in terms of the difference between the click-retreat technique and systematic desensitization.

Abstract:
The purpose of this experiment was to compare the effects of combining negative reinforcement and positive reinforcement during teaching with the effects of using positive reinforcement alone. A behavior was trained under two stimulus conditions and procedures. One method involved presenting the cue ven and reinforcing successive approximations to the target behavior. The other method involved presenting the cue punir, physically prompting the target behavior by pulling the leash, and delivering a reinforcer. Three other behaviors were trained using the two cues contingent on their occurrence. The results suggest that stimuli associated with both a positive reinforcer and an aversive stimulus produce a different dynamic than a situation that uses positive reinforcement or punishment alone.

Abstract:
Escape maintained behavior in dogs is generally displayed by one of two behaviors-fleeing or aggression. Once aggression is negatively reinforced by the removal of the aversive stimulus, it is very difficult to eliminate from the organism's repertoire. Counterconditioning is the process of pairing a positive reinforcer with an aversive stimulus in the attempts that an organism will no longer exhibit fear responses in its presence. This process must be done gradually with small approximations. Many organisms have been trained to tolerate the presence of aversive stimuli via counterconditioning. However, this process can be time consuming and has inconsistent results. The purpose of this experiment was to monitor the effects of counter conditioning around an aversive stimulus while simultaneously training an identical behavior in the presence of a neutral stimulus. The results demonstrated that even though counterconditioning produced approach to the aversive stimulus the subject still exhibited numerous fear responses when results were compared to the control condition.

Abstract:
With a rise in concern for animal welfare, the equine world has started using positive reinforcement (R+); as such, horses often experience a combination of negative reinforcement (R-) and R+. I compared the effects of R- to a combination of positive and negative reinforcement (R-/R+) training. Horses were trained to walk across two visually discriminable liverpools (striped, Experiment 1; colored water, Experiment 2), each associated with either R- or R-/R+, and training type alternating across six days. I measured highest training criteria reached, prevalence of undesirable behaviors, salivary cortisol (pre- and post-training), time spent by the trainer in motionless human tests (pre- and post-training), and horses' preference for the two liverpools using concurrent choice. Across both experiments, I found no significant difference in the proportions of criteria reached between training types; horses engaged in mugging for longer periods of time in R-/R+ than R-; no significant difference between training types for the pre- to post-change of cortisol; a greater proportion of horses increased time spent with R-/R+ trainer than the R- trainer; and no difference between first choice in the preference test or time horses spent in proximity to the liverpool, based on the training type with which the liverpool was associated. Overall, I found few differences between R-/R+ and R-, which could be due to horses only having 30 min total training contact with either training, or my use of relatively low intensities of R- and R+.

The equine world has started using positive reinforcement (R+), such as providing treats. Often horses experience a combination of negative reinforcement (R-) and R+, such as having rein pressure released and being given a treat. I compared effects of R- to a combination of positive and negative reinforcement (R-/R+) training. Horses were trained to walk across two visually distinct liverpools, a 1 m X 2.7 m shallow pool, (striped, Experiment 1; colored water, Experiment 2) each associated with either R- or R-/R+, and training type alternating across six days. I measured highest training level reached, occurrence of undesirable behaviors, salivary cortisol (a measure of stress), time spent by the trainer in motionless human tests, and horses' preference for the two liverpools. Across both experiments, I found no significant difference in the proportions of criteria reached between training types; horses investigated the trainer for treats for longer durations in R-/R+ than R-; no significant difference between training types for the pre- to post-change; a greater proportion of horses increased time spent with R-/R+ trainer than R- trainer; and no difference between first choice in the preference test or time horses spent in proximity to the liverpool, based on the training type with which the liverpool was associated. Overall, I found few differences between R-/R+ and R-, which could be due to horses only having 30 min total training contact with either training, or my use of relatively low intensities of R- and R+.

Full text
Abstract:
The study examined the effects of positive verbal reinforcement on intrinsic motivation by determining differential effects over four multidimensions of Ryan's Intrinsic Motivation Inventory (IMI). Subjects (N=60) were 30 male and 30 female college students. The subjects were blocked by gender and randomly assigned to a positive verbal reinforcement group or a control group. The subjects received 10 trials on the stabilometer. The results of the study indicated that there were significant group differences for composite intrinsic motivation and for perceived competence; however, there were no significant gender differences found. Furthermore, no group differences were reported for the underlying factors of interest/enjoyment, effort, or pressure/tension.

Abstract:
The effect of complete social isolation in the critical periods of early postnatal ontogenesis on the learning and epileptic activity in Wag/Rij rats with a genetic predisposition to the absence epilepsy was studied. The different learning tasks with positive reinforcement (the Intellicage test) and punishment (the two-way active avoidance in the “shuttle box”) were used. It was found that a 3-hour daily social isolation of rat pups from the mother and siblings in early postnatal ontogenesis changes the learning ability and its connection with epileptic activity in adulthood depending on the period of isolation. The isolation from 2th to 8th postnatal day led to a decrease of epileptic activity and improved the learning with positive reinforcement in adult rats. The isolation from 9th to 15th postnatal day improved the learning a conditioned avoidance response with punishment and induced the interrelations between epileptic activity and the active avoidance learning. The isolation from 16th to 22th postnatal – 14 – Global science. Development and novelty day led to an improvement of positive reward-related learning and formation of the significant interactions between epileptic activity and the learning with positive and negative reinforcement.

Abstract:
The article analyzes the peculiarities of the media content shaping and transformation in the convergent dimension of cross-media, taking into account the possibilities of augmented reality. With the help of the principles of objectivity, complexity and reliability in scientific research, a number of general scientific and special methods are used: method of analysis, synthesis, generalization, method of monitoring, observation, problem-thematic, typological and discursive methods. According to the form of information presentation, such types of media content as visual, audio, verbal and combined are defined and characterized. The most important in journalism is verbal content, it is the one that carries the main information load. The dynamic development of converged media leads to the dominance of image and video content; the likelihood of increasing the secondary content of the text increases. Given the market situation, the effective information product is a combined content that combines text with images, spreadsheets with video, animation with infographics, etc. Increasing number of new media are using applications and website platforms to interact with recipients. To proceed, the peculiarities of the new content of new media with the involvement of augmented reality are determined. Examples of successful interactive communication between recipients, the leading news agencies and commercial structures are provided. The conditions for effective use of VR / AR-technologies in the media content of new media, the involvement of viewers in changing stories with augmented reality are determined. The so-called immersive effect with the use of VR / AR-technologies involves complete immersion, immersion of the interested audience in the essence of the event being relayed. This interaction can be achieved through different types of VR video interactivity. One of the most important results of using VR content is the spatio-temporal and emotional immersion of viewers in the plot. The recipient turns from an external observer into an internal one; but his constant participation requires that the user preferences are taken into account. Factors such as satisfaction, positive reinforcement, empathy, and value influence the choice of VR / AR content by viewers.

Abstract:
Original objectives The general goal of the project was to utilize the bactericidal potential of curcumin- functionalizednanostructures (CFN) for reinforcement of food safety by developing active antimicrobial food-contact surfaces. In order to reach the goal, the following secondary tasks were pursued: (a) further enhancement of the CFN activity based on understanding their mode of action; (b) preparing efficient antimicrobial surfaces, investigating and optimizing their performance; (c) testing the efficacy of the antimicrobial surfaces in real food trials. Background to the topic The project dealt with reducing microbial food spoilage and safety hazards. Cross-contamination through food-contact surfaces is one of the major safety concerns, aggravated by bacterial biofilm formation. The project implemented nanotech methods to develop novel antimicrobial food-contact materials based on natural compounds. Food-grade phenylpropanoidcurcumin was chosen as the most promising active principle for this research. Major conclusions, solutions, achievements In agreement with the original plan, the following research tasks were performed. Optimization of particles structure and composition. Three types of curcumin-functionalizednanostructures were developed and tested: liposome-type polydiacetylenenanovesicles, surface- stabilized nanoparticles and methyl-β-cyclodextrin inclusion complexes (MBCD). The three types had similar minimal inhibitory concentration but different mode of action. Nanovesicles and inclusion complexes were bactericidal while the nanoparticlesbacteriostatic. The difference might be due to different paths of curcumin penetration into bacterial cell. Enhancing the antimicrobial efficacy of CFN by photosensitization. Light exposure strengthened the bactericidal efficacy of curcumin-MBCD inclusion complexes approximately three-fold and enhanced the bacterial death on curcumin-coated plastic surfaces. Investigating the mode of action of CFN. Toxicoproteomic study revealed oxidative stress in curcumin-treated cells of E. coli. In the dark, this effect was alleviated by cellular adaptive responses. Under light, the enhanced ROS burst overrode the cellular adaptive mechanisms, disrupted the iron metabolism and synthesis of Fe-S clusters, eventually leading to cell death. Developing industrially-feasible methods of binding CFN to food-contact surfaces. CFN binding methods were developed for various substrates: covalent binding (binding nanovesicles to glass, plastic and metal), sonochemical impregnation (binding nanoparticles to plastics) and electrostatic layer-by-layer coating (binding inclusion complexes to glass and plastics). Investigating the performance of CFN-coated surfaces. Flexible and rigid plastic materials and glass coated with CFN demonstrated bactericidal activity towards Gram-negative (E. coli) and Gram-positive (Bac. cereus) bacteria. In addition, CFN-impregnated plastic material inhibited bacterial attachment and biofilm development. Testing the efficacy of CFN in food preservation trials. Efficient cold pasteurization of tender coconut water inoculated with E. coli and Listeriamonocytogeneswas performed by circulation through a column filled with CFN-coated glass beads. Combination of curcumin coating with blue light prevented bacterial cross contamination of fresh-cut melons through plastic surfaces contaminated with E. coli or Bac. licheniformis. Furthermore, coating of strawberries with CFN reduced fruit spoilage during simulated transportation extending the shelf life by 2-3 days. Implications, both scientific and agricultural BARD Report - Project4680 Page 2 of 17 Antimicrobial food-contact nanomaterials based on natural active principles will preserve food quality and ensure safety. Understanding mode of antimicrobial action of curcumin will allow enhancing its dark efficacy, e.g. by targeting the microbial cellular adaptation mechanisms.
