The present paper discusses the importance of using dynamic analyses to provide a better understanding of the structural response of asphaltic pavements. To this end, the Newmark’s algorithm was implemented for linear elastic and viscoelastic constitutive models in a Finite Element system. Quasi-static and dynamic analyses using different pulse loads where carried out in order to evaluate the differences in the structural responses generally used in mechanistic pavement design: (i) displacement on top of the asphalt surface layer; (ii) tension stress at the bottom of asphalt surface layer and (iii) compression stress on the top of the subgrade.

Cowpea (Vigna unguiculata (L.) Walp.), is very important crop for feeding the rural and urban populations of the tropical and subtropical areas of the world. The yield of that crop varies, mainly, because climate variations and of the use of low yield genetic materials with undesirable characteristics. Grains yield is influenced by the effects of environments (E), genotypes (G) and G × E interaction that into account the variabily of the genotypes in the several environments. The interaction G x E can be characterized by studying the adaptability and stability phenotipic using several techniques. This research aimed to verify the magnitude of the interaction G x E, their effects or the adaptability and the phenotipic stability of the productivity of grains of fifteen cultivate of cowpea. Four methodologies were used for this study (Eberhart and Russel, Cruz, Torres and Vencovsky, Lin and Binns and AMMI or “Additive Main effect and Multiplicative Interaction "). The experiments were carried out in five countries (“Alto Santo, Barreira, Crateús, Itapipoca and Limoeiro do Norte”) of the state of “Ceará”, Brasil, under rainfall conditions during the years of 2006 and 2007. A complete randomized design with 15 treatments and four replication were used. Each experimental unit were 3,0 m x 5,0 m, with four rows spaced by 0,75 m containing 20 plants 0,25 m apart. The two central rows were harvested for futher analysis. The extra plants in each experimental unit were thinning 15 days after sowing, leaving two plants per rows. The Eberhart and Russell linear regression did not classified the cultivars tested for general adaptation and stability; it means that all cultivars were considered unstable by this methodology. The bissegmented regression methodology proposed by Cruz, Torres and Vencovsky allowed to classify the cultivars as adaptable for favorable, unfavorable environment and for general adaptation, but all of than were considered unstable. The method of Lin and Binns classified the cultivars simultaneously for adaptability and stability with just a parameter in decreased order of sequence. The AMMI method made possible the explain most of the G x E interaction in the first two IPCA. This method classified the cultivars and environment in relation to the stability in two biplots in a pricise way. The f Spearman’s correlation indicated that some parameters used by the methodologies mentioned were associated and so they can not be used simultaneously. On the other hand, the one that were not associated be used as a complementarity. The list genotypes that showed highest adaptability and stability for grain yield were “Inhuma, BR 17 – Gurguéia, BRS-Marataoã, Sempre Verde-CE, BRS-Paraguaçu e BRS-Rouxinol” because they combined both parameters.

The castor bean is an oil seed crop, and the oil present in the seeds has several industrial applications. Recently it has been suggested to be used as a renewable fuel (Biodiesel). As a consequence the crop has assumed a relevant ecological and economic importance. Two field studies were conducted in 2003, 2004 and 2005, with the objective of evaluating the behavior of castor bean grown at different times and spacing and under irrigated and rainfed conditions. The experiments were carried out at the "Fazenda Experimental do Vale do Curu", belonging to the Universidade Federal do Ceará, Brazil. In the first experiment the castor plant cv. BRS 149 Nordestina was sown at four different times of planting combined with two irrigation regimes. In the second experiment, two cultivars were evaluated (BRS 149 Nordestina and Mirante 10) seeded in three plant spacing and two different times. Irrigation was more profitable at the beginning of the cycle, prior the rain season than at the end of the rain period, at the end of the plant growth cycle. The combination of the anticipation of the sowing in January of 2004 with the use of irrigation promoted increments in the seed yield and number of racemes for plant and higher weight and number of fruits per raceme. Irrigation yielded better results when was associated with the earliness of planting, as compared with application of water at the end of the raining season. The seeds of the secondary and tertiary racemes possessed greater oil content and seeds weigh. When sowed in December of 2003 the primary racemes produced very light seeds. In the experiment of 2005 the following results were observed: the combination of anticipation of sowing with irrigation promoted increases of the height of the plant, number of lateral branches and the number of internodes, delayed flowering and increased grain yield. Under rain red conditions the number the number of fruits per raceme was reduced. Secondary racemes were responsible for the higher proportion of total seed yield, followed by the tertiary racemes. The cv. BRS 149 Nordestina showed higher seed weigh and oil content. Under irrigation condition the weigh of the seeds increased, independent of the spacing or cultivar used. The early planting associated with the irrigation practice reduced the oil content of the seeds.

The use of the medicinal plants is one of the oldest weapons maids for the treatment of the human illnesses and it is very already known regarding its use on the part of the popular wisdom. The sacred grass (Cymbopogon citratus (DC.) Stapf) it is a medicinal and aromatic plant, belonging to the family Poaceae. This work had as objective determines the planting spacing, the cut height and the ideal age of first cut, seeking to obtain the largest income in essential oil. For this, was settled in December of 2004, an experiment, in the area of Experimental Farm of the valley of Curu (F.E.V.C.), belonging to the Agrarian Sciences Center of the Federal University of Ceará, located in the municipal district of Pentecoste/Ce. The referred experiment was composed of the following treatments: three spacings (0,5m x 0,5m; 0,5m x 0,8m and 0,8m x 0,8m); three different times from first cut (04, 06 and 08 months) and two cut heights (15cm and 30cm of the soil), with 04 repetitions, being accomplished more two cuts in each treatment in intervals of 04 months. The used experimental delineation was in blocks at random in factorial outline 3 x 3 x 2. The obtained data were transformed for productions by hectare. As for the cut age, the best production of essential oil was obtained to the six months, the same if not verifying for the matter dries that had continuous growth. The begin of the crop to the six months after the planting in the 0,5m spacing between plants and 0,5m among rows promoted the largest production of dry matter and of the essential oil of sacred grass. About the cut height, as much the biomass production as the income of essential oil they were higher in the height of 15cm of the soil. Therefore, the C. citratus should be cultivated in the spacing 0,50m x 0,50m, picked the height of 15cm of the soil, with first harvest to the 6 months of age and consecutive cuts every four months to obtain the largest income in essential oil.

As maiores capturas da lagosta Panulirus laevicauda (Latreille), ocorrem na costa do nordeste brasileiro. A relação entre o comprimento (L) e a idade (t), definida como curva de crescimento, é de fundamental importância para o estudo da dinâmica de populações, e portanto, para a investigação pesqueira. No presente trabalho, utilizamos dados de comprimento do abdómen de lagostas da espécie Panulirus laevicauda (Latreille), capturadas em águas costeiras do Estado do Ceará (Brasil), para o cálculo de nova curva do seu crescimento e idade. A estimativa do comprimento máximo teórico, anteriormente feita por Santos & Ivo (1973) , não está de acordo com as observações de campo, conforme referência dos próprios autores. No presente trabalho, foram utilizados apenas os dados das amostragens realizadas nos meses de janeiro, abril, julho e outubro de cada ano, agrupados em intervalos de 0,5 cm, num total de 2.469 indivíduos (tabela I). Não foram considerados os sexos.

Sour sop, Annona muricata, is an Annonaceae specie crop that is growing gradually in the Northeast region of Brazil. Although it is difficult to handle, considering the control of its diseases and pests that occur to it is one in such a way how much complicated, this fact does not intimidate the producers of pulps, ices cream, juices, therefore the promising consuming market causes profit. The fruit borer, Cerconota anonella, and the seed borer, Bephratelloides spp are the most important pests that attack sour sop orchard. The seed borer is a very complex group which is found all growing areas around the world. Both represent the most important pests for their damage to the fruit and loss to growers. In spite of the economic importance played by sour sop, scientific studies to improve its growing methods are scarce. Considering these introduction, with the objective to evaluate the potential of natural and synthetic products in the control of the fruit and seed borers, an experiment was conducted in the Experimental Station of the Embrapa in Pacajus - Ce, from March to September of 2005. A completely randomized design was used in a 4x2x2 factorial, where four products had been used: natuneem, watery extract of Licania rigida, endosulfan (Thiodan CER Bayer CropScience) and Deltamethrin (Decis 25 CER, Bayer CropScience); two intervals of application; and fruit uncovered and covered with tissue-not-tissue (TNT) G-16, adding up to 18 treatments, each one with 9 replications. The Tukey test was used to compare the averages gotten for both insects, but it was necessary to use the Dunnet test in the results of fruit borer. For both pests the Abbbott test of efficiency was used. For the fruit borer, the covering fruit and application intervals did not affect the outcome of results. Deltamethrin and Endosulfan attained the highest efficiency for controlling the fruit borer (%E = 50,60). There were no differences on intervals of application and covering the fruit. The Treatments don’t showed satisfactory efficiency. On the order hand for the seed borer, covering the fruit was also significant. The Test of efficiency of Abbott pointed those treatments Licania extract applied every 28 days and uncovered fruit; endosulfan applied every 14 days + covered fruit; endosulfan applied every 28 days + covered fruit; deltamethrin applied every 14 days + covered fruit; deltamethrin applied every 14 days + uncovered fruit; deltamethrin applied every 28 days + covered fruit and deltamethrin applied every 28 days + uncovered fruit as higher percentages (%E = 39,51). The performance of the treatments against Bephratelloides spp. did not reached satisfactory percentage of efficiency.

The goals of this dissertation are study of sodium hypochlorite and chlorhexidine as irrigants, through a literature review, evaluate and quantify, by means of bacterial culture, the antibacterial effect of biomechanical preparation and pulp-based hydroxide calcium with or without 1% chlorhexidine on bacteria in root canals of permanent teeth after necrotic injury, as well as verifying the presence of microorganisms Fusobacterium nucleatum and Black Pigmented Bacillus in these teeth. The sample consisted of 13 teeth, totaling 11 patients. Microbiological samples were taken after the coronal opening (A1), after root canal preparation (A2), followed by the use of intracanal dressing (A3) and 72 hours of the removal of the medication (A4). The samples were collected sequentially introducing three sterile absorbent paper cones inside the root canal for one minute. In A1, 100% of samples were positive, and the average colony forming units (CFU) of 7.7 x 104. In the second collection (A2), 5 / 13 samples were positive, with an average of 1.7 x 103 CFUs. After use of the medication (A3), 4 / 13 samples were positive, averaging 3.3 x 103 CFUs. A4, 6 / 13 samples were positive, with an average of 1 x 104 CFUs. Between A1 x A2, A3 and A1 x A1 x A4, we observed a reduction of CFUs was statistically significant (p <0.001). We were unable to observe a statistically significant difference (p> 0.05) among the other samples. We conclude that chemo-mechanical performs its antibacterial function by significantly reducing the number of micro-organisms from the main channel, but calcium hydroxide and its association with chlorhexidine 1% had no statistically significant difference, having an antibacterial effect limited not being able to prevent bacterial growth after its use as an intracanal medication.

The objective of this study was to verify the presence of maxillary morphologic parameters on the Obstructive Sleep Apnea Syndrome (OSA) The sample was consisted on maxilla dental models of 23 individuals (11 males and 12 females) with the polyssonographic diagnosis of mild SAOS, 34 individuals (17 males and 17 females) with moderate SAOS and 17 individuals with severe SAOS (14 males and 3 females) Measures of maxilla dental models of 50 young Brazilians were used for the control group, both males and females and with normal occlusion and without any indication OSA The results found show that the maxillary morphologic parameters evaluated didn’t show the association with the apnea/hypopnea index (AHI) but minor transversal dimensions of the maxilla mainly at the level of the molars associated to the increase of the dessaturation of oxyhemoglobin (minSaO2) The individuals with OSA also presented maxilla transversal dimensions narrower and more height on the palate at the region of pre-molars and molars when compared to the control group.

Aim: Compare the effectiveness of four different substances, e.g., 1% chlorhexidine, 3% vancomycin, 10% vancomycin and 1,23 % sodium fluoride, in the reduction of Mutans streptococci (MS) in children with dental caries. Methods: Seventy one children, with ages between 4 and 8 years, were randomly assigned to one of four groups. The antimicrobial agents were prepared as gels and applied during 6 consecutive days, in previously fabricated custom trays. Saliva samples were collected before treatment application (D1), on the last day of treatment (D6), 15 (D15) and 30 days from day 1 (D30). For microbiological analysis samples were placed on MSB Agar medium, incubated at 37o C, under microaerophilic condition for 48 hours and then reading was performed in order to identify number of colony forming units (CFU)/mL. Results: When comparing D6 and D1 the following results were observed: Vancomycin 10% (p = 0.0008) and Chlorhexidine (p = 0.0001) expressed significantly lower bacterial counts. Comparisons between D30 and D1 revealed that Fluoride and Chlorhexidine demonstrated a return to baseline values (D1), while Vancomycin 3% (p = 0.004) and 10% (p = 0.003) generated significantly higher counts in D30 than baseline. At D6 Vancomycin 10% (p = 0.0001) and Chlorhexidine (p = 0.000) expressed the lowest bacterial counts when compared to Fluoride (Mann-Whitney test), with no statistically significant difference between these two groups (p = 0.24) being observed. Conclusions: In the present study, after 6 consecutive days of topical administration, 1% Chlorhexidine gel demonstrated to be as effective as 10% Vancomycin gel in salivary MS reduction in children with dental caries. However, 1.23% Sodium Fluoride and 3% Vancomycin gel demonstrated to be equally ineffective. In conclusion, the use of a 1% Chlorhexidine gel during 10 minutes, for 6 consecutive days demonstrated a great efficacy in salivary MS reduction in children with caries, not leading to bacterial counts higher than what was initially observed.
