Subjetividade e Redes Sociais na Internet: Problematizando as novas relações entre estudantes e professores na contemporaneidade
Authors: Margarites Ana Paula Freitas , Sperotto Rosária Ilgenfritz
Published: May 2019

A reflexão aqui apresentada se dá a partir de uma pesquisa realizada em 2010, que buscava acompanhar as interações - através de blogs, Twitter e Facebook - entre professor e estudantes dos cursos de Bacharelado em Design Gráfico e Digital da Universidade Federal de Pelotas. A metodologia referencia-se na cartografia, abordagem que problematiza os ideais de cientificidade, possibilitando outra aproximação com os “achados” do estudo. Considera-se que as redes operam não só como extensão da sala de aula, mas possibilitam aprendizagens com referências de tempo e espaço diferentes dos instituídos, viabilizando outros modos de ser estudante e professor.

Monitoring species of mammals using track collection by rangers in the Tilarán mountain range, Costa Rica
Authors: Arévalo J. Edgardo , Méndez Yoryineth , Vargas Sergio
Published: May 2019

Although monitoring of animal populations for informed decision making is fundamental for the conservation and management of biodiversity, monitoring programs are not widely implemented. In addition, monitoring plans often represent an economic burden for many conservation organizations. Here we report on the monitoring of five focal species of mammals in the Tilarán mountain range, Costa Rica. We used a participatory approach in which trained rangers of four institutions conducted trail surveys in an area of ca 50,000ha to determine the presence/absence of the paca (Cuniculus paca), collared peccary (Pecari tajacu), tapir (Tapirus bairdii), jaguar (Panthera onca) and puma (Puma concolor) using track collections. Permanent transects of 3 km were sampled on the same day every month in 2000-01 (141 km) and 2009-10 (303 km). Four of the five focal species were registered in our sampling. One of the most valuable outcomes of the study was the initiative of the rangers to train community members to participate in the monitoring plan. We believe that this participatory approach not only has great potential for the integration of rangers in long term monitoring, but also the incorporation of citizen science-based programs. Multi-institutional collaboration for species monitoring could reduce costs and increase the sampling effort.
Diet and foraging behavior of a female Baird’s tapir (Tapirus bairdi) in a Costa Rican lowland rainforest
Authors: Foerster Charles R. , Vaughan Christopher
Published: May 2019

The Baird’s tapir (Tapirus bairdii) is an endangered neotropical species which has little field research to guide its conservation efforts. For this reason, the diet and foraging activity of a free ranging female was observed for 286 hrs. from June 1995 to April 1996 in Corcovado National Park, Costa Rica. She consumed 126 plant species (percents: 35.2 vines, 34.1 trees, 15.9shrubs, 14.8 herbs). Three plant genera accounted for 40% of her diet for the entire study: Monstera sp. (Areaceae), Persea sp. (Lauraceae), and Psychotria sp. (Rubiaceae). Her food consisted of 67.0% leaf matter, 18.6% fruit, 11.7% stem, 2.1% bark and 0,1% flower. More fruit and bark were consumed in the wet season and more stem in the dry season. Average time spent feeding was 29.7%, standing chewing 33.4%, moving chewing 7.6%, standing not chewing 5.7%, moving not chewing 20.1% and in social encounters 2.1%. In the wet season more time was spent feeding and chewing while moving and less time moving without chewing. Means for number of paces and bites in ten minute periods were 42,9 and 49,7 respectively. More paces and bites were recorded in the wet season. Average biomass consumed per bite (dry wt.) over a three month period was 3.32 g, for a yearly estimate of 4,307 Kg of dry mass. For an estimate of 200 tapirs in the park, total biomass consumed would be about 861,400 Kg yearly. The tapir is an important mammal in the dynamics of neotropical forests for its roles as keystone browser and potential seed disperser.
Sex differences in the composition of the natural diet of Panulirus argus (Decapoda: Palinuridae) in the eastern of the Gulf of Batabano, Cuba
Authors: Martínez Coello Diana , Lopeztegui Castillo Alexander , Amor Marrero Ulises
Published: May 2019

The spiny lobster Panulirus argus is one of the most valuable fishery resources in the Caribbean Sea. This is the only species of lobster that has commercial importance in Cuba. This study was aimed to identify the organisms that conform the natural diet for both sexes of P. argus and to determine the importance of each prey in the diet of each sex. A total of 30 stomachs of commercial lobsters (≥ 76mm of carapace length) was analyzed. The identified content was grouping by items and classified for species if it was possible. The total weight of each item was determined and the gravimetric method was applied to estimate the relative weight of the principal diet components. The most frequently consumed prey was also determined. Items with high, middle or low importance were established by the relative importance index (IIR). Similarities between both sexes diet were estimated by similarity index (ISe). Stomachs were extracted of lobsters captured in a fishing zones from eastern of the gulf of Batabano. The predation pressure (P) on the mollusks species found in the stomach content was calculated based on the respective opercula. It was possible to identified 15 feeding entities (12 in females and 14 in the males) being the preferences: crustacean rests (100%), shell rests (80%), vegetable rests (70%), opercula (63%) and mineral rests (53%). Those preference entities were the same between sexes although in the males the foraminifera and the mineral rest were included. The IIR showed crustaceans as a single group of high importance. The gravimetric analysis showed crustaceans as the most consumed prey (62.3% in females and 40% in males). The opercula of Lobatus gigas, Turbo castanea, Fasciolaria tulipa, Nassarius antillarum, Cerithium sp and Tegula fasciata were found. Tegula fasciata showed the highest predation pressure (2.25 in females and 2.14 in males) and together Cerithium sp. they were the most abundant species (60.5% and 33.9% respectively). Respect to the weight of stomach contents the Mann-Whitney test showed no significant difference between females and males. The diet of both sexes of P. argus in the assessed area was similar (ISe=96.75%) and it was constituted mainly of crustaceans and mollusks.
Habitat use and surface activity scorpion Centruroides margaritatus in Palo Verde, Guanacaste National Park, Costa Rica
Authors: Ramírez-Arce Daniel
Published: May 2019

Centruroides margaritatus is one of the most common scorpions in Costa Rica, however almost null ecological or population-based studies have been conducted. Therefore, the objective of the present study was to characterize the habitat use and surface activity of this species in Palo Verde National Park, Costa Rica. Scorpions were searched intensively along transects at three sites: road, camp and forest. The microhabitat in each capture was characterized and the surface activity of the scorpions was recorded at the time of capture. C. margaritatus was found in different microhabitats: soil, leaf litter, herbaceous plants, shrubs, trees, and under rocks and fallen logs, with a preference to use vegetation to heights less than 50 cm. The scorpions were in an ambush behavior most of the times and were observed mostly in the vegetation, while they were in a resting behavior mainly under fallen trunks and rocks. The use of vegetation can represent a strategy to obtain food and also be in a safe place against predators. Nevertheless, the species adaptability provides the ease of using many microhabitats in sites where vegetation is scarce. While the study period was short, this research provides the first observations about the habitat use of this species in Costa Rica, which serves as a basis for future investigation.

Authors: Montalvo Guadamuz Víctor , Sáenz Bolaños Carolina , Ramírez Carvajal Shirley , Carrillo Jiménez Eduardo
Published: May 2019

Santa Rosa National Park, Guanacaste Province, protects one of the largest remnants of dry forest in Mesoamerica. It is considered an example of how to regenerate forest in an area that for many years was used for cattle. A proper management requires knowledge of trends in mammal populations. We chose species that demand high ecologic integrity. the jaguar (Panthera onca ) and other felines, and their potential prey. Using trace count we assessed abundance on seven trails systematically sampled in 2001 and later in 2011. In 2011 we found more traces of jaguars, less of cougars and the same number for ocelots. In the second sampling we found less herbivores and frugivores, and more omnivores. We believe that the trace method is reliable, rapid and cheap.

Published: May 2019

The alternating current magnetic characteristics of the ferromagnetic materials act a significant factor to reflect their stress states. To reveal the relationship between the stress and the magnetic properties of the ferrimagnetic steels, we deduce the relation of alternating current permeability and the detected voltage of the nine-feet probe by using the basic laws in magnetism and law of electromagnetic reaction, and then we use the nine-feet probe to design and build the electromagnetic measurement system. Next some corresponding experiments were carried out to test the induction voltage of the two kinds Q-steel samples under the different stress. The results were shown that there was a similar variation tendency of the detected voltage in the two kinds the Q-steel samples, the max different values of the detected voltage can be reach 150 mV in the Q215 sample and 280 mV in the Q275 sample, respectively. Therefore, with the help of the difference detected voltage we can check the stress state of the ferrimagnetic steels conveniently in the engineering.

Mechanical behavior investigation of Longmaxi shale under high temperature and high confining pressure
Authors: Lu Hui-Jun , Hu Dong-Feng , Zhang Ru , Li Cun-Bao , Wang Jun , Ren Li
Published: May 2019

Triaxial compression tests are conducted on Longmaxi shale under high temperature and high confining pressure condition corresponding to a depth of 3000 m for two typical bedding plane orientations (0? and 90?). It is found that the crack initiation stresses and crack damage stresses of the Longmaxi shale specimens with different vein orientations are different, reflecting that the inclination of the bedding plane has a non-negligible influence on the microcrack initiation and propagation. In addition, the brittleness index of the Longmaxi shale with a bedding plane orientation of 90? is greater than that with an orientation of 0?, which confirmed that the brittleness index is related to the structural orientation under a high temperature and high confining pressure condition. Concerning the failure patterns, both the shear and tensile fracture modes has been observed.
The air-flow structure and gas dispersion behavior in gas tunnel construction through bench cut method
Authors: Liu Rong , Ren Song , Fan Jinyang , Wu Fei , William Ngaha
Published: May 2019

The inability to accurately predict the in rush of gas increases the fear of field workers security and unnecessary investments in tunnel ventilation. In this study, a 3-D numerical model was established to investigate the air-flow structure and gas diffusion characteristics of a gas tunnel during construction. The result showed that the flow inside the bottom bench mainly came from the re-circulation zone of the upper bench. Mutation in the tunnel section due to bottom bench excavation would cause the formation of some air circulation in the bottom bench. The circulation air in the bottom bench came from the re-circulation zone of the upper bench, while the air-flow in the considered zone was a polluted air. Based on the obtained results, there was no accumulation of CH4 inside the bottom bench. Nevertheless, gas gushing will still appear during the construction of the bottom bench surface, which can possibly lead to gas disaster. This study aims to provide some guidance for tunnel engineers on safety monitoring systems.

Authors: Zhang Sheng , Qiao Yang , Zhao Hong-Bao
Published: May 2019

The original displacement value of fracture process zone can be obtained by digital image correlation technology. According to the virtual crack model, the formula to obtain the opening displacement is given in the experiment. Basing on the damage Mechanics theory and the actual deformation characteristics of fracture process zone, the traditional opening displacement distribution function of fracture process zone is modified by defining the wave coefficient and the damage factor of the horizontal elastic modulus. The measured opening displacement is compared with the opening displacement of the traditional theoretical function and modified function, and the results show that the opening displacement is non-linear fluctuation characteristic distribution influenced by damage. The revise distribution function not only reflects the overall growth trend of the opening displacement, but also reflects the local fluctuation characteristics. It has an important theoretical significance for understanding the non-linear characteristics of rock fracture process.

Under a frame of 2 ? 2 matrix Lie algebras, Tu and Meng [9] once established a united integrable model of the Ablowitz-Kaup-Newel-Segur (AKNS) hierarchy, the D-AKNS hierarchy, the Levi hierarchy and the TD hierarchy. Based on this idea, we introduce two block-matrix Lie algebras to present an isospectral problem, whose compatibility condition gives rise to a type of integrable hierarchy which can be reduced to the Levi hierarchy and the AKNS hierarchy, and so on. A united integrable model obtained by us in the paper is different from that given by Tu and Meng. Specially, the main result in the paper can be reduced to two new various integrable couplings of the Levi hierarchy, from which we again obtain the standard heat equation and a special Newell-Whitehead equation.

Technical Review: Indirect Tire Pressure Monitoring Systems and Tire Vibrations
Authors: Muhammad Adnan
Published: May 2019

Indirect tire pressure monitoring systems (ITPMSs) have been an active area of research for the past 2 decades. Researchers worldwide have strived to develop estimation techniques for the detection of the change in tire pressure by using the vibration information present in the speed signal. Different groups have used a torsional vibration model for the tire, owing to its torsional stiffness and rotational moment of inertia. The standard antilock braking system (ABS) speed sensor signal is analyzed for these vibrations. Different estimation algorithms try to detect the change in this vibration frequency, which indicates the change in the torsional stiffness of the tire as a result of variation in the pressure.

Tire vibrations have been studied in great detail for the past 5 decades, and there are various models of tire vibrations available in the literature. These models range from physics-based analytical models to finite element models (FEMs). Analytical models take benefit from the mathematics developed for rotating elastic thin shells and plates, whereas FEMs use simulation tools to develop vibration models of the tire.

A detailed literature survey of ITPMSs and tire vibration models reveals that there is no correlation between the vibrations detected in the speed signal and the vibrations predicted in the tire vibration models. Researchers have developed tire vibration models that do not take into consideration the effects of vibrations on the speed signal; although, to the best of our knowledge, signal processing and estimation experts who have developed methods for ITPMSs have not validated the true source of observed vibrations in the speed signal and could not present a viable theoretical explanation.

In this review, a comprehensive study of the ITPMS techniques and tire vibration models is presented, with an aim to find a correlation between them. The review begins with a brief introduction to the topic followed by state of the art, then a detailed review of ITPMSs and the methods for their realizations in the automotive industry. Finally, tire vibration models are presented in detail, and possible links between vibration models and ITPMS vibrations are sorted.

Preliminary Evaluation of Anti-Listerial Bacteriocin-like Peptide Produced by Enterococcus lactis PMD74 Isolated from Ezine Cheese
Authors: Uymaz Tezel Başar
Published: May 2019

Enterococcus lactis PMD74 is a novel strain with a notably high antimicrobial activity. The present study evaluated the anti-listerial effect of a bacteriocin-like peptide (BLIP) produced by E. lactis PMD74 isolated from Ezine cheese (PDO). The strain was screened for its antimicrobial activity against 22 indicator strains using both agar spot and well diffusion methods. We observed that the neutralized cell-free supernatant (CFS) of E. lactis PMD74 exhibited varying levels of antimicrobial activity against both closely and distantly related pathogenic strains, with the highest activity displayed against Listeria monocytogenes strains. Although thermostable and resistant to lysozyme treatment, BLIP could be completely inactivated by trypsin, proteinase K, and Î±-chymotrypsin treatments. BLIP production starts in the early exponential growth phase of E. lactis PMD74 (3 h incubation, 400 AU mL–1) and reaches its maximal production (6400 AU mL–1) at the end of the exponential growth phase. Moreover, it is stable in the pH range of 2.0 to 7.0. The treatment of cultures of L. monocytogenes ATCC 7644 and Escherichia coli ATCC 26922 with sterilized CFS exhibited bactericidal and bacteriostatic effects, respectively. Furthermore, co-inoculation of L. monocytogenes ATCC 7644 and E. lactis PMD74 in skim milk led to complete loss of viability of L. monocytogenes ATCC 7644. These findings suggest that BLIP produced by E. lactis PMD74 could serve as a promising food preservative agent owing to its bactericidal and bacteriostatic properties.

O cajá (Spondias mombin L.) apresenta elevada aceitação devido ao seu sabor exótico. O entendimento do processo de maturação deste fruto é um fator decisivo para se estabelecer padrões de identidade e qualidade, propiciando a previsão da vida útil pós-colheita, além de permitir a utilização adequada dos frutos em estádios de máxima qualidade gustativa. Portanto, este trabalho tem como objetivo avaliar as mudanças na qualidade de frutos de cajazeiras de ocorrência no Brejo Paraibano durante a maturação. Os frutos foram colhidos em cinco estádios de maturação, sendo que cada fruto corresponde a uma repetição, totalizando 80 frutos para as avaliações físicas (coloração da casca, índice de cor da casca, comprimento, diâmetro, massa fresca dos frutos e firmeza) e a polpa de quatro repetições de vinte frutos para as físico-químicas (acidez titulável, sólidos solúveis, relação SS/AT, pH e ácido ascórbico). Os dados foram submetidos à ANOVA e ao teste de Tukey. Frutos dos estádios início de pigmentação (IP), amarelo esverdeado (AV), verde amarelado (VA) e totalmente amarelado (TA) apresentaram maiores massa, comprimento e diâmetro. A transição da cor verde para a amarela ocorreu entre os estádios IP e VA. Frutos do estádio TA se destacaram como mais saborosos, pelos maiores teores de sólidos solúveis (15,42%), relação SS/AT (7,40) e significativo aporte de ácido ascórbico (37,85 mg.100g-1), que valoriza o seu consumo.
