Optimization techniques for a 2D Engine

This document contains the description of the development of a small 2D engine written in C++. The focus of this project is to implement various optimization techniques to have a performant application. The result is a small 2D engine that can be executed in any Windows machine and can handle more than 10.000 entities interacting with each other in real time.

Improvement of grafting procedures for the ornamental species: II. Abies concolor [(Gord. & Glend.) Lindl]

The achieved results concerning the grafting silver-fir - Abiesconcolor [(Gord. & Glend.) Lindl] scions on white-fir (Abies alba Mill.)rootstocks are reporting in this article. The double-side-veneer grafting method and the plastic tape and the ecological Ceraltin® wax were applied in four experimental variants. The side-veneer-grafting method and the classic materials, such as raffia and the hot wax were used at the two controls involved in this experiment. The grafting success expressed in percents, were transformed in arcsin square root of percent values, and a two-way analysis of variance was performed. Highly significant (p <0.001) statistical differences were found between grafting variants, including controls. The Duncan Multiple Range Test showed that the four experimental grafting variants were highly significantly (p < 0.01) better than the two controls. The grafting success of the best experimental variant has surpassed the two controls by 129 and 153%, respectively.Consequently, the double-side-veneer grafting method, the new developed plastic tape and the ecological Ceraltin® wax have contributed to this grafting success owing to which they are recommended to be used for grafting silver-fir ornamental trees

The effect of consumer involvement in light lamb meat on behavior, sensory perception, and health-related concerns

Involvement can explain behavioral consequences, such as consumer decision-making and consumption. The first aim of this study is to identify the profiles of consumers based on their involvement in light lamb meat. The second aim is to study the influence of involvement on consumers’ attitudes, behaviors, beliefs, preferences, quality cues, and sensory perception regarding light lamb meat. Two consumer profiles are identified. The first cluster includes consumers who enjoyed eating light lamb meat, were conscious of their self-image, and perceived the consequences of poor choices; these consumers also perceived the probability of making an incorrect choice as high. The second cluster includes consumers who truly loved eating lamb meat, were also conscious of their self-image, and perceived the consequences of poor choices; however, these consumers were confident in not making incorrect choices. Although both involvement-based profiles showed high involvement in light lamb meat, it can be concluded that the second cluster had a higher involvement. In general, the involvement-based profiles did not influence health-related attitudes, preferences, or sensory perceptions of light lamb meat, while beliefs, behavior and quality cues were influenced by involvement

Plant-derived extracts feed-addition and packaging type influence consumer sensory perception of pork

This paper investigates whether the combination of the addition of extracts derived from plants (plants derived extracts, PDE) to pork feedstuff and the meat conservation conditions (packaging and time exposure) affect consumers’ perception of pork quality, studied by means of visual appraisal, purchase intention and a home test. The three PDE groups were control, garlic extract and blended oil composed by carvacrol, timol, cynamic aldehide and eugenol extracts. Meat was packed in film, vacuum or modified atmosphere (MAP) packaging. A visual test was designed comprising a four-day storage step followed by a four-day exposure step in a refrigerated island display case. All studied effects influenced visual appraisal scores, being time exposure and packaging effects more noticeable than PDE or pig-sex effects. Meat from MAP scored higher than the rest. Scores decreased as exposure time increased, but this evolution was less perceptible in vacuum packaging and was faster for meat from the garlic group. Only gender affected the visual appraisal scores, with women scoring higher than men. Neither PDE addition nor pig sex affected to purchase intention whereas both exposure time and packaging type did. A maximum of 2 days of exposure would be recommended. In the home-test, meat from male pigs obtained higher scores than meat from female pigs, and none of the consumer-related effects influenced the given scores

The role of emotions in the public sphere: M. C. Nussbaum proposal

¿Qué papel puegan las emociones en el juicio moral? ¿Y cómo pueden contribuir a la formación de una sociedad democrática más justa y estable? El propósito de este artículo es analizar cómo la filosofía, el arte y las humanidades en general juegan en tal sentido un papel inexcusable. Necesitamos ir más allá de las teorías contractualistas de la justicia, nos dice Nussbaum. La nueva propuesta de justicia habrá de fundamentarse en el hecho del pluralismo y de la globalización de los problemas, pero también en un cosmopolitismo humanista que asuma nuestra huama y compartida finitud y vulnerabilidad.How can emotions enable a fairer and more stable democratic society? The aim of this essay is to emphasize the importance of emotions in M.C. Nussbaum’s thought and how can they contribute to reinforce democracy and provide it with stability to in the context of political liberalism. All of this seems to require, according to Nussbaum, the integration of the role of emotions in society’s educational project, so as to go beyond the model of justice focused on the mutual benefit, widening it with another, whose centre of gravity would be the capacities and the human development. In this sense, it is necessary to ask ourselves about the role Humanities should play, so as to provide such a project with feasibility and continuit

Web-based survey of consumer preferences for the visual appearance of meat from suckling kids

Most suckling kids are raised on farms oriented toward cheese production, and many goat farmers’ rear kids with milk replacers. The aim of the current study was to investigate the consumer preferences for the visual appearance of meat from suckling kids reared with milk replacers or natural milk. Meat colour was the major criterion used to select meat. The meat of Cabra del Guadarrama reared with milk replacers was preferred by 72% of consumers and had a preferred lightness and hue angle. The rearing system did not influence preference through the time of display. Web-based surveys provided similar information to information recorded with live surveys using actual products instead of pictures. Meat colour appears to be a recurring intrinsic cue to assess consumer preference. In general, consumers preferred meat of light suckling kids reared on milk replacers because this meat had a high lightness and hue angle as well as a low chroma
