Análise dos índices dos efeitos multiplicadores e das ligações para trás e para frente da renda, do produto e do emprego: uma abordagem a partir da matriz de contabilidade social do Brasil
(Universidade Salvador, 2018-08) CARVALHO, André Cutrim; CARVALHO, David Ferreira
The main objective of this paper is to analyze the multiplier effects of income, output and employment, as well as the inter-sectorial backward and forward linkages of income, output and employment of the key industries of the Brazilian economy in the years 2000, 2005 and 2010, based on Social Accouting Matrix (SAM) of Brazil. The research sought to analyze the interactive impacts caused by the transformation industry in its own internal sectors and sectors of other industries that form the Brazilian industrial system. The chain indices of dispersion power and dispersion sensitivity of the manufacturing industry over all sectors of the industrial system of the Brazilian economy based on SAM were also analyze. The article found that income that exceeds the portion of the purchase of inputs was spending by households, using the channels that result in extra demand on the products of the agricultural sector, through the liquid circular effect of Stone. Therefore, it strengthened demand links, which, in turn, catalyzed the process that led to the spread of national GDP growth. The role of the manufacturing industry is thus perceive as a key industry for the country's economy, especially as the back bond index and the forward index are high and their coefficients of variation low.

(Universidade Federal do Pará, 2024-02-21) BARBOSA, Bruna Lopes; FELÍCIO, Karem Miléo; http://lattes.cnpq.br/5289063715182942
The Type 1 Diabetes Mellitus (T1DM) is characterized by the destruction of the ß-cells resulting in loss of endogenous insulin production. It is one of the most common presentations of youth-onset diabetes. The treatment needs multi-disciplinary approach and is based on intensive insulin therapy. The chronic hyperglycemia and severe insulin deficiency are known to be associated with impaired linear growth. The dysregulation of the GH-IGF-1 axis in T1DM is characterized by decreases in circulating IGF-1, GHR and GHBP, along with increases in GH and IGFBP-1. This study evaluated the influence of glycemic control in the linear growth of T1DM patients treated at Universitary Hospital João de Barros Barreto and compared the growth of these patients with the WHO`s reference. For that, a retrospective cohort study was made using data from medical records at the period between 5 and 19years old from 78 patients (40 females/ 38 males) following the criteria of age at the diagnosis £ 15 years old (females) and £ 17 years old (males). They were at diagnosis 8,6 years old, the duration of the disease was de15,4 years, glycated hemoglobin (HbA1C) 10,5 %. Among them, 58 patients (28 females/ 28 males) were achieved the final height (FH). The female’s FH was 156,2cm (Z score -1,11SDS) and the male’s FH was 166cm (Z score -1,45SDS). Only 19% were above the OMS`s media. But 26% had short stature. 9% were at Z≤ -3SDS. HbA1C ≥ 9,5% was related with worse FH. Each 1% of elevation in HbA1C was associated with a reduction of 2,23cm on FH, and 26% of FH variability were influenced by HbA1C level. The ones with HbA1C ³ 9% had significant stature loss compared to TH. In conclusion, the T1DM patients evaluated were shorter than the media of WHO`s charts, however the majority did not have short stature. HbA1C levels were negatively associated with stature loss compared to TH and final heigh. There was no correlation between FH and weight, insulin total dose, gender and diabetes duration.

(Universidade Federal do Pará, 2006) CASTRO, Andréa Bezerra de; GUIMARÃES, Diva Anelie de Araújo; http://lattes.cnpq.br/2891287458034896
The data for this work was acquired in the dependences of the Zoo Botanic Park of the Museu Paraense Emilio Goeldi during the years of 1992 to 1997. The objective was to study the reproductive biology and the growth of the Scorpion Mud Turtles in captivity. Thus, a verification was made of the biometrical correlations and the sexual dimorphism between males and adult females, the type of reproduction and the number of eggs per clutch, the incubation period and the percentage of eclosion, the connection between the size of the eggs and the hatching, and between the biometrical data of the female with its eggs and hatchling, the biometric growth and the weight of the species, the age when the sexual dimorphism occurs in the young ones and the age of the first oviposition. A group of adults and 70 hatching of the Zoo Botanic Park was used. Data obtained demonstrated that the adult males (n=75) had a long tail and a black pigmented head and presented an a average weight of 314,05 g, carapace length of 14,79 cm, carapace width of 9,79 cm, plastron length of 12,3 cm, plastron width of 7,46 cm and 4,5 cm of height. The adult females (n=176) had a short tail and yellow head, and had an average weight of 430,08 g, carapace length 1,26 cm, carapace width of 11,31 cm, plastron length of 13,35 cm, plastron width of 8,01 cm and 5,51 cm of height. All the studied variants showed significant differences between the values of adult females and the adult males. The mating season was from April until August, characterizing a seasonal reproduction. The nest building occurred between the months of May and September and was divided in the following phases: deambulation, opening of the hollow, oviposition, closing of the hollow and abandonment of the nest. There was no difference between the number of eggs laid by young or adult females. The average number laid by an adult female was 2,45 with a variation of 01 to 07 eggs and by a young one was 2,7 with a variation of 02 the 07 eggs. However, the eggs of the adult females were bigger in weight, length and width than that of the young females. The eggs had a pink colored elongated form, with a white spot in the center and the rind was hard and smooth (n=701), and they presented average weight, length and width of respectively 9.6 g, 3.8 cm and 2.0 cm. The incubation period was 136 days, varying between 111 and 164 (n=426) and an eclosion of 86,61%. The carapace weight, the width, and the width of the plastron of the females were determinative for the weight and width of the eggs. The weight and width of the eggs were determinative for the weight, carapace length and plastron length of the newborn. The young (n=887) were born with an average weight of 6,5 g, carapace length of 3,1 cm, carapace width of 2,2 cm, the plastron length of 2,7 cm, plastron width of 1,8 cm and carapace height of 1,6 cm. The weight and measures of the female were determinative for the weight, and measures of the newborn. At 22,49 months of age, there appeared the first signals of sexual dimorphism. The species showed a positive correlation between the weight and the biometric length, width and hight until the 37,95 months of age, after that age the ponderal continued to increase while the rate of increase of the length was smoother. With 37,94 months the standard deflexion of the ponderal weight was the largest seen on all ages, probably as the result of the sexual dimorphism already present at this age. At this age it was seen the first oviposition of the group that had a carapace with 11,84 cm of length. At 47.02 month the group showed an average weight of 410,9 g and 14,15 carapace length, values similar to the ones found in the studied adult animals.

Crescimento e produção de pirarucu, Arapaima gigas, sob diferentes densidades de estocagem em associação com búfalas leiteiras
(Universidade Federal do Pará, 2001-10) IMBIRIBA, Emir Palmeira; LOURENÇO JÚNIOR, José de Brito; http://lattes.cnpq.br/2919433679918544
With the objective of evaluating four stock densities of pirarucu (Arapaima gigas) and to identify the one that provides the best productive performance, in length and weight gain to make possible its intensive culture, a research was carried out, during 360 days. using the densities of 5, 10, 15 and 20 fishes per 100 m2 of inundate area. Live tilapias (Tilapia nilotica), captured in a dam used for milk buffaloes management, equivalent to 6% of the pirarucu live weight, were used during four days per week. The design was completely randomized with four treatments and two replications. The data were analyzed on the basis of the application of the exponential model of growth. Mathematical expressions were obtained for each stockage density. Simple linear regression analysis were made. - However, until the first 120 days, no significant difference in weight could be observed among the four study densities. The values of the angular coefficient of the relation weight/length of pirarucu showed that its growth is of the allometric type. The maximum total size was 107.66 cm and the maximum weight was 13.43 kg, in the density of five fishes per 100 m2. However, the highest biomass, of 85.69 kg per 100 m2, was observed in the density of 10 fishes per 100 m2, suggesting that this density would be the most adequate for using in intensive systems. The excellent ponderal development of pirarucu, indicates the potential use of this species, in intensive systems associated with buffaloes.

Growth curve of female collared peccaries (Pecari tajacu) raised in captivity in the Brazilian Amazon Region
(2013-08) GARNERO, Analía del Valle; MARCONDES, Cíntia Righetti; ALBUQUERQUE, Natália Inagaki de; ARAÚJO, Ronyere Olegário de; LE PENDU, Yvonnick; GUIMARÃES, Diva Anelie de Araújo
This work aims to determine the most suitable nonlinear model to describe the growth of female collared peccaries (Pecari tajacu). The monthly records of the weight of 10 captive female collared peccaries over a period of two years in the Brazilian Amazon Region were used. The growth models used were the Von Bertalanffy, Brody, Gompertz and Logistic. The parameters were estimated by using the NLIN procedure from the SAS application. The criteria used to verify the adjustment of the models were: asymptotic standard deviation (ASD); coefficient of determination (R2); average absolute residual deviation (ARD) and the asymptotic rate (AR). The Brody model and the Logistic model estimated the highest (19.44kg) and the lowest (19.18kg) asymptotic weight (A), indicating the lowest (0.0070kg/day) and the highest (0.0121kg/day) maturation rate (K). These results and the coefficients of phenotypic correlation that varied from -0.75 and -0.47 confirmed the antagonistic nature between these parameters. The Brody model estimated the lower value for ARD, a limiting factor for describing the lowest value for AR through this model. The Brody model showed the best adjustment for AR, although the other models also showed a suitable adjustment to the weight data of said species/gender. Based on the AR obtained in this work, the Brody model is recommended for adjusting the growth curve of the female collared peccaries. Depending on the estimated values, especially for K, this trait can be included in a selection index.

Redescription of megalopa and juvenile development of Pachygrapsus gracilis (Decapoda: Grapsidae) from the Amazon region, reared in the laboratory
(2011-08) ARRUDA, Danielle Cristina Bulhões; ABRUNHOSA, Fernando Araujo
This present study re-describes the megalopa stage and provides detailed morphological descriptions and main growth changes observed in stages I through VII of the juvenile instars of the dark shore crab Pachygrapsus gracilis (Saussure, 1858), from the Amazon region. The specimens in this study were reared in the laboratory and the megalopae were collected at Ajuruteua beach in northeastern Pará, Brazil. Previous studies had described the megalopa of P. gracilis from Mexican waters, as well as those of Pachygrapsus transversus (Gibbes, 1850) and Pachygrapsus marmoratus (Fabricius, 1787). A comparison between the Mexican and Amazonian populations of P. gracilis revealed significant morphological differences. The main difference is the presence of 3 elongated setae on the 5th pereiopods of individuals of the Amazonian population. The setal number and their arrangement in the appendages also differed. In P. gracilis, the male and female genital openings are observed from the juvenile instar III, whereas differentiation in male pleopods is observed only in juvenile instar V. In females, the pleopods undergo rapid differentiation during juvenile instar VI. These morphological comparisons and other observations on development are briefly compared and discussed with reports for other species.
