SEQUENTIAL SAMPLING AND MICROSATELLITES FOR EVALUATION OF THE GENETIC QUALITY IN CORN SEEDS LOTS

In the seed production system, genetic purity is one of the fundamental requirements for its commercialization. The present work had the goal of determined the sample size for genetic purity evaluation, in order to protect the seed consumer and the producer and to evaluate the sensitivity of microsatellite technique for discriminating hybrids from their respective relatives and for detecting mixtures when they are present in small amounts in the samples. For the sequential sampling, hybrid seeds were marked and mixed in with the seed lots, simulating the following levels of contamination: 0.25, 0.5, 1.0, 2.0, 4.0, and 6.0%. After this, groups of 40 seeds were taken in sequence, up to a maximum of 400 seeds, with the objective of determining the quantity of seeds necessary to detect the percentage of mixture mentioned above. The sensitivity of microsatellite technique was evaluated by mixing different proportions of DNA from the hybrids with their respective seed lines. For the level of mixture was higher than 1:8 (1P1:8P2; 8P1:1P2), the sensitivity of the marker in detecting different proportions of the mixture varied according to the primer used. In terms of the sequential sampling, it was verified that in order to detect mixture levels higher than 1% within the seed lot- with a risk level for both the producer and the consumer of 0.05- the size of the necessary sample was smaller than the size needed for the fixed sample size. This also made it possible to reduce costs, making it possible to use microsatellites to certify the genetic purity of corn seeds lots.

Remoção de matéria orgânica e nitrogênio de efluentes provenientes de abatedouros de bovinos por meio de reator aeróbio operando em bateladas sequenciais com adição de coagulante químico

The volume of liquid effluent generated in cattle slaughterhouses is quite high and cannot be released untreated in water bodies due to its high pollution load of predominantly organic origin. To minimize the environmental impacts of its industrial wastewater and meet the local environmental legislation, abattoirs shall make the treatment of these effluents. The present work aims to develop the study of a reactor by sequential batch pilot scale, in order to optimize their performance in treating wastewater from a cattle slaughterhouse. The treatment system used was developed and installed in the Laboratory of Wastewater Treatment, in Faculty of Science and Technology UNESP, Presidente Prudente campus. The procedure used followed the operation of sequential batch reactors, in which all processes and treatment operations occurring sequentially in a single unit, by establishing specific operating cycles, which comprise the following separated phases: aerobic reaction, anoxic reaction, sedimentation and emptying. Aiming to improve the quality of treatment was planned the addition of coagulant Poly Aluminum Chloride (PAC) in the reactor, by determining their optimal dosage by Jar-test trials. Were prepared four steps with specific operating cycles: step one or acclimatization (10 hour of aeration, one hour and 30 minutes of sedimentation and 30 minutes for exchanging the effluent); step 2 (6 hours of aeration or aerobic phase, 4 hours and 45 minutes of stirring or anoxic phase and 1 hour and 15 minutes for sedimentation and exchange effluent); step 3 (2 hours and 30 minutes of aeration, 8 hours and 15 minutes of stirring and 1 hour and 15 minutes for sedimentation and exchange) and step 4 (2 hours of aeration, 8 hours and 45 minutes of stirring and 1 hour and 15 minutes for sedimentation and exchange)...

Coroa da terra: a poesia como (re)criação do mundo

This monograph is aimed at reflecting the internal structure of the book Coroa da Terra (1946), the Portuguese poet Jorge de Sena (1919-1978), investigating for this, the guiding criteria for the ordering of poems. Starting from a question posed by an author paratext, we considered the possibility that the book is constituted as a unit of poetic path, in which each poem comprises a stretch of the pilgrimage undertaken by the poet toward the crown of the Earth. Moreover, from the epigraph of the book and the Preface (1960) of 1st edition of Poesia I (1961), we consider the idea that the Coroa da Terra is a search for truth, or even that the pilgrimage made by the poet is on the trail of a poetic word conscious and therefore ethically responsible. This search would set the poetic language of testimony, from which derive two other important vectors for the exegesis of poetry seniana: metamorphosis and pilgrimage. Upholding the unity of the book would be the language in dialectical flow as a formal procedure, which enables the poet be an expression in constant motion. To check the validity of our hypothesis, we conducted an analysis of four poems in sequential order (―Purgatório‖, ―Suma Teológica‖, ―Os trabalhos e os dias‖, ―Espiral‖). To them, it was added to analyze the poem ―Metamorfose‖, poem 23rd of the Coroa da Terra, which acted as a reference point and as close to the research by presenting a character's thought seniano synthesis. It was found that the idea of unity is sustained when we consider Coroa da Terra as a journey of formative poetic direction

Tratamento de efluentes provenientes de abatedouro de bovinos por meio de reator enzimático seguido de reator aeróbio operado em bateladas sequenciais

Brazil has one of the largest cattle herds in the world, so the cattle slaughter is one of the most important economic activities in the Brazilian market. But this activity requires a high demand of water, resulting in serious problems about the correct disposal of wastewater generated in the process. This effluent has a high pollution load, becoming its receiving bodies (streams and rivers) unfit for various activities such as public water supply, recreation, fisheries. To minimize the environmental impacts of its industrial wastewater and fallow the local environmental legislation, refrigerators must make the treatment of these effluents. This study aimed to verify the efficiency of a enzymatic reactor, when occur hydrolysis of lipids present in the effluent industrial of an cattle slaughter industry. The treatment system used was composed of two separate reactors: one being the anaerobic fluidized bed reactor (AFBR), inoculated with immobilized enzymes on the matrix support, and the other by sequential batch reactor (SBR) inoculated with activated sludge. Whereas, the reactors have been developed and installed at the Wastewater Treatment Laboratory, Faculdade de Ciências e Tecnologia, UNESP, campus Presidente Prudente. The procedure operating occurred differently for each reactor: preparation and inoculation of enzyme granules, filling the reactor, hydrolysis, and AFBR emptying, filling, aerobic reaction, sedimentation, and emptying the SBR. We performed three experimental stages, with the first and second stage of the work were done reactor analyzes separately, and the third step of the analysis were made with the interconnected reactors...

A decoding procedure which improves code rate and error corrections

Corresponding to $C_{0}[n,n-r]$, a binary cyclic code generated by a primitive irreducible polynomial $p(X)\in \mathbb{F}_{2}[X]$ of degree $r=2b$, where $b\in \mathbb{Z}^{+}$, we can constitute a binary cyclic code $C[(n+1)^{3^{k}}-1,(n+1)^{3^{k}}-1-3^{k}r]$, which is generated by primitive irreducible generalized polynomial $p(X^{\frac{1}{3^{k}}})\in \mathbb{F}_{2}[X;\frac{1}{3^{k}}\mathbb{Z}_{0}]$ with degree $3^{k}r$, where $k\in \mathbb{Z}^{+}$. This new code $C$ improves the code rate and has error corrections capability higher than $C_{0}$. The purpose of this study is to establish a decoding procedure for $C_{0}$ by using $C$ in such a way that one can obtain an improved code rate and error-correcting capabilities for $C_{0}$.

Auditory brainstem response in term and preterm infants with neonatal complications: the importance of the sequential evaluation

Introduction Literature data are not conclusive as to the influence of neonatal complications in the maturational process of the auditory system observed by auditory brainstem response (ABR) in infants at term and preterm. Objectives Check the real influence of the neonatal complications in infants by the sequential auditory evaluation. Methods Historical cohort study in a tertiary referral center. A total of 114 neonates met inclusion criteria: treatment at the Universal Neonatal Hearing Screening Program of the local hospital; at least one risk indicator for hearing loss; presence in both evaluations (the first one after hospital discharge from the neonatal unit and the second one at 6 months old); all latencies in ABR and transient otoacoustic emissions present in both ears. Results The complications that most influenced the ABR findings were Apgar scores less than 6 at 5 minutes, gestational age, intensive care unit stay, peri-intraventricular hemorrhage, and mechanical ventilation. Conclusion Sequential auditory evaluation is necessary in premature and term newborns with risk indicators for hearing loss to correctly identify injuries in the auditory pathway.

Sequential healing of the elevated sinus floor after applying autologous bone grafting: an experimental study in minipigs

AimTo describe the sequential healing after elevation of the maxillary sinus mucosa applying the lateral access technique with the use of autogenous bone grafting without membrane to occlude the osteotomy access.Material and methodsImmediately after the elevation of the maxillary sinus Schneiderian membrane, applying the lateral access technique in 10 minipigs, autologous bone was harvested from the lateral aspect of the mandibular molar region and ground into particles with a bone mill. The space under the Schneiderian membrane was filled with this graft. No membranes were placed onto the access osteotomy. The healing was evaluated after 15, 30, 90 and 180days. Paraffin sections were prepared and analyzed histologically.ResultsAfter 15days of healing, the elevated area was mainly filled with provisional matrix, newly formed bone and some remnants of bone chips, and appeared reduced in volume compared with that at the time of surgery. After 30days of healing, further shrinkage of the height of the elevated space was found, with similar percentages of the different tissue components. After 90 and 180days, the area underneath the Schneiderian membrane appeared reduced in volume and condensed toward the base of the sinus. The bone tissues appeared to be more mature, both for the mineralized and the non-mineralized portions, while connective tissue occupied 20% of the space, most likely related to the lack of the use of a membrane occluding the access at the time of surgery.ConclusionsSuboptimal healing outcomes with respect to augmentation of the space under the sinus floor membrane were documented when autologous bone chips were used as a filler and no membrane was applied to cover the access.

Effect of recasting procedure upon corrosion behavior and metallic ion release of Co-Cr-Mo dental alloy in physiological

Recasting process influence upon corrosion behavior of Co-Cr-Mo dental alloy in simulated physiological serum has been investigated using chemical and electrochemical techniques. Recast Co-Cr-Mo alloy by induction (IND) or by blowtorch (FLAME) has exhibited similar dendritic structures. Both IND and FLAME alloys have presented good corrosion resistance in physiological serum. Passivation process provides this corrosion resistance. Codissolution makes this process difficult. Passive films, formed on these alloys, have been analyzed as a dual layer consisting of an inner barrier and an outer porous layer. Passive film protective characteristics are higher in FLAME than in IND alloy. On this last alloy, the passive film is more porous due to a higher Codissolution. ©Carl Hanser Verlag, München.

Purely cortical anaplastic ependymoma

Ependymomas are glial tumors derived from ependymal cells lining the ventricles and the central canal of the spinal cord. It may occur outside the ventricular structures, representing the extraventicular form, or without any relationship of ventricular system, called ectopic ependymona. Less than fifteen cases of ectopic ependymomas were reported and less than five were anaplastic. We report a rare case of pure cortical ectopic anaplastic ependymoma.

Sequential healing at implants with different configuration and modified surfaces: an experimental study in the dog

To evaluate the peri-implant soft and hard tissue adaptation at implants with different modified surfaces and configurations. Six Beagle dogs were used. Mandibular premolars and first molars were extracted bilaterally. After 3 months, full-thickness flaps were elevated, and two different types of trans-mucosal implants (ICX-Gold®, Medentis Medical GmbH, Dernau, Germany and SLActive®, Institute Straumann, Bern, Switzerland) and two different surfaces were randomly installed in the distal regions of one side of the mandible. Abutments were applied, and a nonsubmerged healing was allowed. After 1 month, the procedures were performed in the other side of the mandible, and after a further month, the animals were sacrificed, biopsies were collected, and ground sections prepared for histological examination. Similar results in marginal bone and soft tissues dimensions were observed after 1 month of healing at the two implant systems used, and no major changes could be observed after 2 months of healing. After 1 month, the percentage of new bone was 69.0% and 68.8% at ICX-Gold and SLActive surfaces, respectively. After 2 months, the percentage of new bone was 67.8% and 71.9% at ICX-Gold Medentis and SLActive surfaces, respectively. No statistically significant differences in osseointegration were found. The two implant systems used resulted in similar osseointegration after 1 and 2 months of healing.

Running-based anaerobic sprint test as a procedure to evaluate anaerobic power

The aim of this study was to evaluate the use of the running anaerobic sprint test (RAST) as a predictor of anaerobic capacity, compare it to the maximal accumulated oxygen deficit (MAOD) and to compare the RAST's parameters with the parameters of 30-s all-out tethered running on a treadmill. 39 (17.0±1.4 years) soccer players participated in this study. The participants underwent an incremental test, 10 submaximal efforts [50-95% of velocity correspondent to VO2MAX (vVO2MAX)] and one supramaximal effort at 110% of vVO2MAX for the determination of MAOD. Furthermore, the athletes performed the RAST. In the second stage the 30-s all-out tethered running was performed on a treadmill (30-s all-out), and compared with RAST. No significant correlation was observed between MAOD and RAST parameters. However, significant correlations were found between the power of the fifth effort (P5) of RAST with peak and mean power of 30-s all-out (r=0.73 and 0.50; p<0.05, respectively). In conclusion, the parameters from RAST do not have an association with MAOD, suggesting that this method should not be used to evaluate anaerobic capacity. Although the correlations between RAST parameters with 30-s all-out do reinforce the RAST as an evaluation method of anaerobic metabolism, such as anaerobic power.
