O Teorema de Malgrange-Ehrenpreis
In the first chapter of the dissertation, is a brief introduction. Then in the second chapter, are shown notions and properties of topological vector spaces. Following the present study, the third chapter, is effected the approach to the theory of distributions, which provides, as an example the Dirac delta distribution, in which, therefore, are de ned further distribution operations, including the convolution of a distribution with a test function, and finally, still in same chapter an analysis is made of distributions with compact support. In chapter four, in turn, explains to the Fourier transform and its properties, as well as properties of functions belonging to Schwartz space and also a study is made of tempered distributions. Finally, the fifth and final chapter is shown the Malgrange-Ehrenpreis theorem, which is the main theme of the work done,which states that any differential operator with constant coe cients has a fundamental solution. Thus, it implemented a study of some examples related to the theorem.

Reticulados obtidos por colagem
The main objective of this work is to obtain new lattices through an elementary technique of collage. For any lattices A and B of dimension n and m respectively, this technique allows us to obtain a other lattice (n+m−1) - dimensional. Given two lattices A and B of dimension n ≥ 2 and m ≥ 2 respectively, with an a lattice Λ2, this technique allows us to obtain a new lattice (n+m−2) - dimensional. In particular, given one lattice n - dimensional H , with center density δ , this technique allows us to explicitly obtain a new lattice (n+1) - dimensional H′, with center density δ/√3. Through this method, new lattices are found and will review some of its key parameters such as volume, the minimum distance, the number of vectors of minimum length and center the density.

Desempenho de cordeiros em terminação alimentados com dietas contendo coproduto de caju tratado ou não quimicamente com uréia
This study aimed to evaluate the intake (g/day, per unit metabolic size – UMS, percentages of weight alive) of dry matter (DM), organic matter (OM), crude protein (CP) and neutral detergent fiber (NDF), alimentary conversion, daily weight gain, carcass, commercial cuts and viscus yield and the economical viability of termination of lambs that received experimental isoenergetics and isoproteics diets having growing levels of cashew by-product urea amonized or not urea amonized. Twenty four lambs were distributed in randomly delineation factorial project 4 X 2 with four levels of inclusion (6; 11; 16; 21%) of treat cashew co-product (CCTQ) or not (CCNT) with urea, hay of Aruana grass (Panicum maximum cv. Aruana), maize and cottonseed cake, resulting in eight experimental treatments, with three replications for treatment. The urea amonization didn’t affect the DM, OM and NDF intakes. The diets having higher levels of cashew by-product inclusion provided a larger OM intake, in %WA and g/UMS. The CP intake, in %WA and g/UMS, was larger for animals that consumed CCTQ. The levels of inclusion and with or without cashew by-product chemical treatment didn’t interfere on the slaughter weight, daily weight gain and alimentary conversion of that animals. On the carcass and viscus properties, levels of cashew by-product inclusion affected in the loin weight and yields in leg, loin, neck, rib and breathing system. The heart yield was superior for that animals that consumed CCTQ. On the economical evaluation, the diet that contained 21% of CCTQ provided larger net value and better costbenefit relation

Desempenho reprodutivo de ovelhas Santa Inês criadas no nordeste paraense
The objective of this study was to investigate the reproductive performance of ewes submitted to reproductive station in the dry and rainy periods and to identify the best period of the year to perform reproductive and birth station in Igarapé-açu county,, Pará northeastern. Was used 96 ewes randomly separated in two groups (Group A: 38 animals and Group B: 58 animals). Group A was submitted to the station reproductive in the dry season and birth station in the rainy season with the opposite occurring with the Group B. The reproductive rates were submitted to Chi-square or Fisher Exact test and analysis of variance by t-Student to weight the variables by statistical package SAS (1993). The distribution of estrus showed no significant difference between the seasons (P>0,05). Groups A and B, respectively, showed rates of 86,8% and 93,1% for pregnancy, 76,3% and 79,3% for kidding rate, 9% and 7,4% for abortion rate, 86,8% and 89,6% for fecundity rate, 103,4% and 113% for birth rate, 113,8% and 113% for prolificacy rate, 2,6% and 13,8% mortality rate of ewe and 26,6% and 48% for mortality rate of lambs until 10 days. Only the mortality rate of lambs until 10 days was shown to be statistically different (P<0,05). The matrices showed only difference in weights to the end of the reproductive station and the in the last 45 days of pregnancy (P<0,05),showing better results with animals mating in the dry season. However, no differences between seasons were found on weights at the beginning of breeding season, postpartum and lamb birth weight (P>0,05). The seasons seemed not influence the reproductive performance of ewes reared in this region, however, the ewes must give birth during the rainy season which would ensure higher survival of lambs

Estimativas de componentes de variâncias e de valores genéticos para características de crescimento, reprodução e habilidade materna em ovinos da raça Somalis Brasileira
The aims of this study were to estimate genetic parameters for growth, reproductive and maternal traits and assess the different adjustments of fixed effects in the prediction of breeding values for weight and weight gain at weaning of Brazilian Somali sheep, reared in semi-arid. Data from the Núcleo de Conservação da Embrapa Caprinos e Ovinos, located in the city of Sobral, north of Ceará state, suported by Programa de Melhoramento Genético de Caprinos e Ovinos de Corte (GENECOC). The analyzed growth traits were birth weight (PN), weaning weight (PD), weight gain from birth to weaning (GND), adjusted weight at 84 days (P84), weight gain from birth to 84 days (GN84) and adult weight (PA). The traits related to maternal ability were litter weight at birth (PTCN), litter weight at weaning (PTCD), mother's weight at weaning of the lambs (PW) and ratio of weaning (REL), which is represented by the rate between the total weight of lambs at weaning and the mother's metabolic weight. The analyzed reproductive traits were lambing interval (IP), lambing date (DP) and number of services per conception (NSC). The fixed models of analysis were defined by the MIXED procedure of SAS software, after checking the constraints and limitations of the data. (Co) variances and genetic parameters were estimated by Derivative Free Restricted Maximum Likelihood (DFREML) method using the MTDFREML software. Initially, univariate analyses were performed for each trait and then multivariate analyses were performed. An analysis of correlation of classification or "rank", using the Spearman coefficient, was performed to compare the rank of animals by PD, P84, GND and GN84, based on the additives genetic direct and maternal values. Heritabilities for growth traits estimated in univariate analysis were of low magnitude, ranging from 0.00 to 0.22. There was a trend of increasing of heritabilities in the multivariate analysis. In multivariate analysis for the growth traits, heritabilities for PN-PD-GND and PN-P84- GN84 ranged from 0.00 to 1.00. Genetic correlations also showed large variations, XVII from negative, zero to high and positive, ranging among PN-PD-GND from -1.00 to 0.94 and from -0.45 to 0 97 among PN-P84-GN84. The reproductive traits showed low heritabilities. The heritabilities for maternal traits were higher in the multivariate analysis, with moderates values and high correlation between PTCN and PTCD and unitary negative value between PW and REL. The weaning weight adjusted for the covariate age on the day of weighing and the weaning weight adjusted for standard age at weaning, in this study, 84 days, are traits of distinct natures under analyses. Using these criteria promotes different responses to selection, with different rank orders of animals. However, it was not possible to specify the criteria with better efficiency since the differences between the results were not fully understood

Composição bioquímica do plasma seminal de caprinos sem padrão racial definido (SPRD) em clima tropical úmido
Goat seminal plasma (SP) biochemical composition observed to very in high latitudes due to seasonality. In low latitudes this variation has been attributed only to the low nutritional value of diets in the dry period. The aims of this study were to evaluate the occurrence of variation in the SP biochemical composition of SPRD goats breed intensively in the State of Ceará, Brazil. The experiment was carried out in the facilities of Dep. of Zootecnia of the Federal University of Ceará - UFC. Twenty male SPRD goats were used, they were fed according to NRC/goats (1981). Ejaculated were collected weekly in artificial vagina and eletroejaculador, and evaluated, measure, centrifuged and separated the SP (sobreswing) from the cells spermatic (precipitate), being stored in eppendorff tubes at -18°C, during one year (Sep/2005 the Aug/2006). For analyses purpose weekly sample were mixed to constitute a monthly individual pool, from which were evaluated the concentrations of Ca, P, Mg, PTt, CA and fructose. Significant variation was observed (p <0,05) in the biochemical composition of the SP among the periods of the year, registering the highest levels of biochemical parameters in the rainy period. The individual variation was significant (p <0,01), only having significant interaction animal/period to the fructose (p <0,05). The study of correlations showed significant associations (p <0,0001) among PTt, CA and fructose, among the ejaculate volume and of SP with the components, and of temperature, humidity, precipitation and ITU with the biochemical parameters of the SP. It is concluded that fructose is a good biochemical parameter for the study of seminal quality. However, more studies are necessary to identify the causes of this variation, and to better understand the role of the fructose, citric acid and total proteins in the metabolism spermatic

Estudo genético de características de importância econômica em uma população multirracial de ovinos de corte: uma abordagem quantitativa e molecular
Nowadays, there is great possibility of association between quantitative and molecular genetics. An important impact would be expected in the sheep selection, with the establishment of efficient criteria for meat production selection. The aims of this work were to verify polymorphisms in GDF9, Calpastatine and Aromatase (CYP19) genes; to verify the frequencies of SNP allelic variants in these genes; to verify the effects of these variants on productive and reproductive traits in a multiracial sheep population; to estimate genetic parameters and breeding values of these traits in this population; to verify the effect of genotype of these genes on models to estimate the genetic parameters and to verify the effect of genotype for these genes on estimated breeding values. GDF9 gene is a candidate related to phenotype of high prolificacy. The calpastatine gene has importance on production of meat animals, as it is related to growth and meat quality. Aromatase gene is a candidate affecting the productive and reproductive performance, by its important role in the steroid hormone metabolism. SNP polymorphism of CYP19 gene was investigated by PCR-RFLP technique in a sample of 133 animals from several breed groups of meat sheep. Allelic and genotypic frequencies were estimated for this polymorphism and the effect of these variants on growth,reproductive and maternal traits were investigated, using GLM procedure of SAS software. The studied traits were birth weight (PN), weaning weight (PD), slaughter weight (PA), yearling weight (P1), weight gain from birth to weaning (Gn_d), weight gain from weaning to slaughter (Gdes_abat), weight gain from weaning to yearling (Gdes_ano), age at first lambing (IPP), lambing interval (IP), gestation length (PG), lambing date (DP), total weight of lambs born for female for lambing (PTCN) and total weight of weaned lambs for female for lambing (PTCD). Genetic parameters and breeding values were estimated by Derivative Free Restricted Maximum Likelihood (DFREML) method. The effect of genotype inclusion in analysis models for estimation of genetic parameters was evaluated. The effect of genotype on estimated breeding value was verified. It was not possible to verify the genotype of the animals for GDF9 and Calpastatine genes due the difficulties on the reactions standardizations. So the animals were genotyped only for aromatase gene. In studied sample, it is not observed animals with AA genotype. The frequencies for AB and BB were 0.65 and 0.35,respectively. The allelic frequency did differ among studied breed groups. The aromatase gene presented influence on most studied traits, with difference in this influence according to breed group. The direct heritabilities were 0.21, 0.25, 0.52, 0.39, 0.24, 0.20, 0.21, respectively, for PN, PD, PA, P1, Gn_d, Gdes_abat and Gdes_ano, and 0.01, 0.06, 0.14, 0.06, 0.20 and 0.11, respectively, for IPP, IP, PG, DP, PTCN and PTCD. Positive genetic correlations were estimated among corporal weights. Genetic correlation between Gn_d and Gdes_abat was 0.37 and between Gn_d and Gdes_ano was 0.55. Negative genetic correlations were estimated between IPP with IP and PG. PTCN presented genetic correlation of 0.52 with PTCD. The use of information of genotype of aromatase gene increased the efficiency of models for genetic analyses by BLUP methodology. The animals with AB genotype presented genetic superiority for most studied traits in relation to those with BB genotype. It is possible conclude that the use of marked assisted selection will permit increase the efficiency of selection today in practice with the use of traditional quantitative genetic methodologies

Avaliação de quatro métodos de produção de geleia real e rainhas de Apis mellifera no estado do Ceará
The experiment was conducted at the Faculty Technology FATEC - Wilderness Center in the city of Quixeramobim - CE, and was divided into two stages. The goal of the first phase conducted from February to April 2010 was to evaluate the influence of rearing for royal jelly production and larval weight of Apis mellifera transferred. The second step was evaluated important aspects in the production of queens as the influence of the growing weight of emerging queens, their morphometric characteristics, and dry weight of their ovaries, being conducted from October 2010 to February 2011. Two apiaries were used, a small apiary that received colonies the four models used in the study: Doolittle, Orfanos with a hive, Mini-hive and Chinese, and others to support the same with 25 colonies. Colonies each received a door-frame dome domes containing 32 plastic artificial color blue, 16 in the top batten and the bottom 16. Data collection was done in two days of the week in the first phase of the trial and three days in the second stage. In the first phase, 448 transfers were performed for each larval rearing, a total of 1792 larvae transferred. In the second phase were produced in 263 colonies all the queens. The results showed no significant difference (p > 0,05) in acceptability and weight of larvae transferred, as well as in royal jelly production by growing, but there was a positive correlation between these parameters. There were also the same statistical differences and correlations for the weight of the ovaries and dry matter. The production of royal jelly dome, the weight of the queen to emerge and their morphometric measurements showed statistically significant differences (p <0.05) and Doolittle hive stood out positively on royal jelly production, while Chinese demonstrated the growing queens producing smaller and lighter. We conclude that hive Doolittle are more suitable for the production of royal jelly, since it utilizes a number higher than the domes used in this study, and re-create that Mini-hive in the production of queens.

Sincronização do estro e da ovulação em novilhas girolandas: comparação entre os protocolos hormonais ”cidr-b” e “ovsynch
Two oestrus and ovulation synchronization protocols (CIDR-B and OVSYNCH) were tested on 90 acyclical Girolanda heifers. The animals were distributed in three groups. Group I (n=30) was submitted to the OVSYNCH protocol, consisting of: intramuscular (IM) application of 1.0 ml gonadotropin-releasing hormone (GnRH), 2.0 ml rostaglandin F2a (PGF2a) after 7 days, 1.0ml GnRH 48h later, then timed artificial insemination (TAI) 16h after the second application of GnRH. Group II (n=30) was submitted to the CIDR-B protocol, consisting of: introduction of intravaginal CIDR-B implant and application of 2.0 ml estradiol benzoate (EB) IM, implant removal after 8 days, application of 500 UI pregnant mare serum gonadotropin (PMSG) and 2.0 ml PGF2a, a second IM application of BE 24h subsequently, then TAI 30h later (i.e. 54h following implant removal). Group III (n=30; control group) received no hormonal treatment. Gestation was verified ltrasonographically 35 days after the first, second and third AI. The cost-benefit ratio of each protocol was also determined: The CIDR-B protocol was most efficient in the first AI in which it was comparable to the control group in providing a near-natural oestrus quality (conception and pregnancy rates of 60% and 50%, respectively; p<0.05). In the second AI, the two treatments yielded similar pregnancy rates, but differed in conception rates (96% for CIDR-B; 76% for OVSYNCH). Thus the CIDR-B protocol was the more efficient in inducing puberty in Girolanda heifers, featuring the best conception and pregnancy rates in the first AI and considerably reducing age at first birth. It is moreover economically feasible as the implant may be reused provided apropriate care is given to hygiene and handling.

A Curvatura de Gauss-Kronecker de hipersuperfícies mínimas em formas espaciais 4-dimensionais
In this work we study complete minimal hypersurfaces with constant Gauss-Kronecker curvature in a space form Q4(c). We prove that the infimum of the absolute value of the Gauss-Kronecker curvature of a complete minimal hypersurface in Q4(c); c ≤ 0; whose Ricci curvature is bounded from below,is equal to zero. Futher, we study the connected minimal hypersurfaces M3 of a space form Q4(c) with constant Gauss-Kronecker curvature K. For the case c ≤ 0, we prove, by a local argument, that if K is constant, then K must be equal to zero. We also present a classification of complete minimal hypersurface of Q4 with K constant. Examples of complete minimal hypersurfaces which are not totally geodesic in the Euclidean space R4 and the hiperbolic space H4(c) with vanishing Gauss-Kronecker curvature are also presented.

O estado e o desenvolvimento desigual
The 5th Congress The unequal geographically development is discussed here as a condition for the reproduction of the capital in its contemporary phase, taking the action of the State as an important explanatory factor. In that sense, it is observed that the worsening of the regional inequalities in Brazil and in Bahia, starting in the 1950s, had in the governmental performance a decisive aspect, revealing a great contradiction, in the sense that, in spite of the leading class is constantly trying to combat the regional inequalities, in reality what it is doing is implementing public politics that integrate competitiveness just in certain areas.
