Contextual Interference Effect Depends on the Amount of Time Separating Acquisition and Testing  [PDF]
Jefferson John dos Santos, Flavio Henrique Bastos, Thiago de Oliveira Souza, Umberto Cesar Corrêa
Advances in Physical Education (APE) , 2014, DOI: 10.4236/ape.2014.42014

Considering the critical role permanence has on predictions related to the contextual interference effect, this study sought to determine whether the manifestation of the effect depends on the time interval separating the acquisition phase (AQ) from the retention test (RT). Four groups of blocked (BL) and four groups of random practice (RD) performed 90 trials of a dart throwing task (AQ) and were tested exclusively after 10 minutes (BL10 and RD10), 24 hours (BL24 and RD24), 7 days (BL7 and RD7) or 30 days (BL30 and RD30). In the AQ, blocked groups performed three blocks of trials, with each block consisting of throwing the darts from one of three distances (2 m, 2.6 m and 3.2 m). For the random groups, the trial order was pseudo-randomized. The results indicated superior performance of RD24, compared to BL24, but no difference was found between the groups tested after 10 minutes, 7 days or 30 days. Thus, our results do not support the notion that higher contextual interference promotes immediate learning benefits nor long-term retention of internal representations. Nevertheless, future research should further investigate the processes underlying the contextual interference effect, since short-term gains (24 h) were found.

Abstract: the apodi/mossoró basin is one of the most important water resources in the state of rio grande do norte. recent studies have shown that nitrogen compounds stand out among the river's main contaminants. there is thus a need to relate their presence to other physicochemical properties that influence their formation. this paper aims to correlate the concentrations of no3-, no2- and nh3 with the values of ph, t, eh and do in the waters of this basin. the results indicate the predominance of a strongly oxidizing environment, highlighting no3- as the main form of nitrogen present, even in places where significant reductions in eh and od were observed. this paper gives a contribution for the development of control and treatment of sources of pollution and better management of water resources.

Orbital : the Electronic Journal of Chemistry , 2012,
Abstract: Porphyrins are very attractive compounds due to their wide application in many areas of new materials as chemical technology, ecology, medicine and, electronics. In the last years, they are also been a focus of attention owing to their implications to many photocatalytic reactions. Cardanol (isolated form cashew nut shell liquid) and glycerol (side product of biodiesel industry) are raw materials of low aggregated value; however, they hold chemical structures with functionalities that can lead to products of high commercial value to Brazilian industry. Aiming to use these chemical materials, our research group has proposed the synthesis of new hybrid molecular structures of porphyrin-cardanol-glycerol, which will be submitted to test of their photocatalytic properties. The synthetic proposal is based on the reaction of 4-hydroxybenzaldehyde (1) and epichloriridine (2) (derived from glycerol), using pyridine in dichloromethane and FeCl3 as a catalyst, under reflux and stirring. This process will provide the mixture of intermediate 3 and 4. These compounds will be attacked by the nucleophile cardanol (5) in sealed tube, using pyridine and dichloromethane at 120 oC for 80 hours, giving the intermediate 6. After oxidation of the alcohol 6, the corresponding ketone will be achieved. Continuing the synthesis, these intermediates will separately react with pyrrol, giving the wished porphyrins that in turn will be transformed in macromolecules by treatment with Grubbs catalyst, according to methodologies already known in the literature. The previously synthesized compounds 3, 4, 5 and 6 had their structures confirmed by spectroscopy analyses of NMR (1H and 13C). Porfirinas s o compostos muito atrativos devido a sua ampla aplica o em muitas áreas de novos materiais como a tecnologia química, ecologia, medicina e eletr nica.

Abstract: This research sought to study the compatibility between the molasses and the entomopathogenic fungi Beauveria bassiana (Balsamo) Vuill on the control of Cosmopolites sorditus Germar, 1824. The study was conducted on the Site Pitiá in a banana plantation of approximately 250 m2, located in the municipality of Areia, state of Paraiba, Brazil. The results showed that the constancy of C. sorditus was significantly higher in traps consisting of molasses+fungi (P <0.01). And significantly lower in traps without yeast and molasses. The frequency of C. sorditus was classified as accidental in traps with only B. bassiana (23.44%) and in traps without the addition of B. bassiana and molasses (10.71%), and being accessory in traps consisting of molasses (28.43%) and in traps with molasses+fungi (37.27%). Therefore the food bait molasses along with the fungi B. bassiana, may be used in an integrated control of C. sorditus in banana plantations.

Abstract: Com o objetivo de se obterem informa es sobre os sistemas de produ o de ovinos e avaliar a frequência de anticorpos contra o vírus da Maedi-Visna (MV) em propriedades localizadas na microrregi o de Juazeiro - BA, investigou-se, a partir da aplica o de questionários, algumas características de manejo sanitário, alimentar e reprodutivo em 58 propriedades nos oito municípios que comp em essa regi o: Juazeiro, Sento Sé, Sobradinho, Pil o Arcado, Campo Alegre de Lourdes, Remanso, Casa Nova e Cura á. Das propriedades visitadas, 89,6% (81,74% - 97,46%) adotavam sistema extensivo de cria o e 58,6% (45,92% - 71,28%) n o tinham assistência técnica. O manejo sanitário mostrou-se precário. Os produtores entrevistados apontaram a linfadenite caseosa como uma das doen as mais observadas nos rebanhos. Analisaram-se 919 amostras de soro pelo teste de Imunodifus o em Gel de Agarose (IDGA) no Laboratório de Patologia Clínica da Embrapa Caprinos e Ovinos, em Sobral - CE. Detectaram-se quatro animais positivos. As Lentiviroses de Pequenos Ruminantes têm demonstrado, em diversos estudos, rela o direta com os manejos adotados nas propriedades e introdu o de tecnologias sem adequado controle sanitário. Acredita-se que o baixo número de ovinos positivos evidenciado neste levantamento deva-se ao baixo índice tecnológico adotado na regi o. Outra possibilidade é de que, nessa regi o, o rebanho de ovinos caracteriza-se pela predominancia de ra as nativas e sem ra a definida (SRD), com poucos animais importados de outros estados e/ou países. In order to obtain data from the used sheep production systems and to analyze them to the occurrence of Maedi-Visna in properties located in the microregion of Juazeiro - BA, some features of health, food and reproductive management were inquired from the application of questionnaires, on 58 properties located in the eight municipalities that make up this region: Juazeiro; Sento Sé; Sobradinho; Pil o Arcado; Campo Alegre de Lourdes; Remanso; Casa Nova and Cura á. This survey evaluated some basic elements in the production chain. It was asserted that 89.6% (81.74% - 97.46%) of the producers raise their animals extensively and 58.6% (45.92% - 71.28%) have no technical assistance. The health management seemed to be precarious. Caseous lymphadenitis is one of most commonly diseases observed by farmers. 919 samples of sheep serum were collected and analyzed by AGID in the Laboratory of Clinical Pathology of Embrapa Goats, in Sobral - CE. Four animals were positive. The Lentivirus of Small Ruminants has been shown in several studies to be direc

Abstract: The aim of this work was to evaluate attributes of dry mass and root morphology characteristics inlines with contrasting drought resistance (two tolerant and two sensitive) from the Breeding Program of CNPMS(Maize and Sorghum National Research Center), under three levels of aluminum saturation (low, intermediate andhigh). A randomized blocks design was used, with two replications for each level of Al-saturation. Evaluations wereperformed at 14 and 28 days after sowing. Root morphology was assessed using the WinRhizo image analysis system.Significant differences were observed for dry matter attributes between lines, especially the sensitive ones. Concerningroot morphology, the drought resistant lines presented higher total root length (RL), root surface area (SA), root volume(RV) and greater very thin roots length (VTRL). In conclusion, lines selected for drought resistance can be indirectlyselected for aluminum tolerance.
