A new species of Microcancilla from the southwestern Atlantic and notes on Microcancilla brasiliensis comb. nov. (Gastropoda, Cancellariidae)

Microcancilla phoenix sp. nov., collected from the Southeast and South coast of Brazil represents the southernmost record of the genus in the Atlantic Ocean. The new species differs from the other congeners of the Atlantic mainly by the presence of microscopic pustules covering the whole shell and by dimensions of the protoconch. “Axelella brasiliensis” Verhecken, 1991, known from the Northeast to South coast of Brazil, is transferred to Microcancilla based on a similar sculpture of microscopic pustules on the protoconch and on other features of the teleoconch discussed in the present study

Devido ao crescente interesse pela noção de competência e a sua importância para a educação, procurou-se incluir nesta visão o campo profissional relacionado à segurança pública, voltado à formação de gestores e agentes de alto nível que trabalham a proteção e defesa civil, tendo como base a Política Nacional de proteção e Defesa Civil brasileira dentro de um contexto mundial. Portanto, para a determinação de desempenho foram desenvolvidas quatro dimensões para análise dos programas dos cursos de pós-graduação elencados neste artigo

Wood vinegar inhibits emergence and initial growth of leucaena (Leucaena leucocephala /Lam./ de Wit) seedlings

The need to investigate species used in forest exploitation and the disposal of their residues and byproducts motivated the evaluation in a greenhouse of the effect of wood vinegar (WV) on seed germination and seedling growth of leucaena (Leucaena leucocephala (Lam.) de Wit) in two substrates. The studied factors were WV concentrations in irrigation water (0.0, 0.4, 0.8, 1.2 and 1.6%) and substrate (sand or vermiculite). Each treatment had four repetitions of 30 seeds in plastic trays. The variables evaluated up to 27 days after sowing were: emergence percentage, emergence speed index, percentage of ungerminated seeds, total seedling length, shoot height, shoot and root dry weight. The concentrations of wood vinegar used in this study had an inhibitory effect on the germination, emergence and initial development of leucaena at all studied concentrations. A large decrease in percentage and speed of germination of leucaena was observed, mainly in the sand substrate. The more intense effect on the germination stage than in later stages of development was caused by substances contained in WV, such as acetic acid, furfural and methanol. The germination, emergence and initial growth of leucaena were less impaired when the substrate was vermiculite. For effective control of leucaena it is necessary to test higher concentrations of wood vinegar

Utilização de resíduos de coco (Cocos nucifera) carbonizado para a produção de briquetes

O presente trabalho teve como objetivo produzir briquetes com finos de carvão de resíduos de coco e avaliar a qualidade dos briquetes. Cascas de coco foram coletadas no APL de coco em Touros - RN. Após secagem ao ar livre por dois meses, as cascas foram carbonizadas em forno de alvenaria tipo "rabo quente JG" e trituradas em moinho de martelo. O pó resultante foi peneirado, utilizando-se a fração inferior a 40 mesh para produção de briquetes em um delineamento inteiramente casualizado envolvendo 12 tratamentos (divididos em três grupos) e três repetições. Como aglutinantes, foram empregados amido de milho e argila. Os tratamentos foram divididos em três grupos, correspondendo cada grupo a uma proporção de argila, respectivamente 12, 15 e 18%, em relação ao peso seco total do briquete. Em cada grupo, as proporções de amido foram de 6, 8, 10 e 12%. O pó de carvão foi misturado com a argila finamente triturada e a seguir foi adicionado o amido pré-gelatinizado em água a 80°C. A massa para cada tratamento foi misturada até completa homogeneização, separando-se quantidades de 17 gramas de massa por repetição. Os briquetes foram produzidos em briquetadeira de laboratório, com pressão de 1.500 psi e tempo de prensagem de quatro minutos. Foram avaliadas as seguintes propriedades dos briquetes: densidade aparente, poder calorífico, composição química imediata (umidade, teores de carbono fixo, matérias voláteis e cinzas) e resistência à compressão. Os melhores tratamentos para fins comerciais foram os 12/12 e 12/15.The present work has the objective to produce briquettes by using fine charcoal from coconut wastes as raw material and evaluate the briquette quality. Coconut piths were collected at the city of Touros, in Rio Grande do Norte state. After a 2- month air drying, coconut pith was carbonized and hereafter ground in a hammer mill. The resulting charcoal powder was sieved and the fraction less than 40 mesh was used to produce briquettes according to an entirely randomized designed experiment involving 12 treatments and 3 replications. Starch and clay were employed as binders. The treatments were divided into 3 groups, each group corresponding to a proportion of clay, respectively 12, 15 and 18%, based on the total dry weight of the briquette. Within each group, the proportions of starch were 6, 8, 10 and 12%. The carbon powder was mixed with finely ground clay was added and then the pre-gelatinized starch in water at 80°C. The mass for each treatment was mixed until homogeneous, separating quantities of 17grams of mass for each repetition. The briquettes were produced in a laboratory press (pressure of1500psi and pressing time of 4 minutes).The briquettes were dried in an oven at 60°C until constant weight. After drying, the properties of briquettes were evaluated: bulk density, high calorific value, immediate chemical composition (moisture content, fixed carbon, volatile matter and ash) and compressive strength. Best treatments for trading products were 12/12 e 12/15

Tooth avulsion accidents due to urgent and emergency orotracheal intubation

Intubation is necessary during critical situations to reduce the risk of death. In Brazil, a need exists to determine the prevalence of tooth avulsions in emergency and urgent care. The objective of this study was to identify the causes of orotracheal intubation (OTI), the number of tooth avulsions, and the avulsed teeth that result from urgent and emergency intubation. The sample consisted of 116 patients (total group) in intensive care units (ICUs) distributed across Group 1 (G1), which was composed of 71 patients from an urgent-care hospital, and Group 2 (G2), which was composed of 45 patients from an emergency hospital. Clinical examinations showed dental alveolus with signs of recent exodontia in the upper and lower anterior regions. Sociodemographic data and the reason for intubation were evaluated. The Shapiro-Wilk normality test, chi-square test, Fisher?s exact test, Mann-Whitney U test, and univariate logistic regression were performed with a significance level of 5%. The avulsion prevalence was 4.3%, with more cases receiving emergency intubation (n=4). All avulsions occurred in adults, and a significant difference (p=0.011) was observed with regard to the elderly. A 1-year reduction in age increased the chance of tooth avulsion during intubation by 1.09 times; being female increased the chance by 2.88 times. Pulmonary problems were the major causes of intubation, with the highest tooth avulsion prevalence observed during emergency intubation. The avulsed teeth were 11, 12, 13, 22, 32, and 33 across all cases

Successful Treatment For Chronic Eosinophilic Leukemia (CEL) With Imatinib Mesylate

We report a case of a patient with Chronic Eosinophilic Leukemia (CEL) with mutation in alfa PDGFR gene exhibiting a satisfactory response to treatment with imatinib mesylate. A 25-year-old man presented in a hematology service with a persistent cough and hemogram alterations. His blood count showed a hemoglobin level of 12.5 g/dL and a white blood cell count of 94,030/mm3, eosinophils were 68% of all cells. Bone marrow aspiration and biopsy showed hypercellularity with marked eosinophilia (77%) and erythroid differentiation series was hypocellular with normoblast maturation. The immunohistochemically of the bone biopsy was positive for myeloperoxidase and negative for CD34/CD99, consistent with CEL. Fluorescence in situ hybridization (FISH) for the beta-fraction of platelet-derived growth factor (PDGFRβ) and Philadelphia chromosome (Ph 1) were negative and the alfa PDGFR (Platelet-Derived Growth Factor) was positive and showed heterozygosis in c.2531T>C on 18 Exon and homozygous in C.2562+1G>A at the region of the splicing site at the 18 intron. Treatment was initiated and maintained by administering 400mg/day imatinib mesylate. Laboratory findings returned to normal ranges, with clinical improvement and a hematological response observed after the second month of therapy. Currently, the patient’s blood count shows the white blood cell count (5,400 total leukocytes), eosinophils (8.6/mm3), hemoglobin (15.5 g/dl), hematocrit (45.4%) and platelets (298,000/mm3) within normal ranges. The mutation search was negative in in peripheral blood one year after the initial treatment. Our work corroborates other studies on the efficacy of imatinib mesylate in the treatment of patients with CSF PDGFR alpha positive. We emphasize the importance of molecular studies, considering its relevance for the correct staging of the disease. Since CEL is a rare disease, it is important to define its etiology and anticipate its treatment, thus minimizing the damage induced by the disease

PHYSICO-CHEMICAL AND ENERGETIC EVALUATION OF WOOD FROM THE SPECIES Piptadenia stipulacea (Benth.) Duckeand Amburana cearensis (Allemao) A. C. Smith IN A SEMI-ARID REGION IN NORTHEAST BRAZIL

A Caatinga \ue9 um bioma exclusivamente brasileiro, que apresenta uma grande variedade de esp\ue9cies da fauna e da flora, sendo uma boa parte destas end\ueamicas. Ao longo dos anos, a supress\ue3o da caatinga por a\ue7\ue3o antr\uf3pica vem reduzindo bastante esse bioma. Este fato se d\ue1, principalmente, pelo uso do potencial energ\ue9tico de suas esp\ue9cies vegetais sem a devida preocupa\ue7\ue3o com a sustentabilidade do mesmo. Um melhor conhecimento do potencial energ\ue9tico das esp\ue9cies vegetais da caatinga possibilita um manejo mais adequado. O objetivo deste trabalho foi avaliar o potencial energ\ue9tico e as caracter\uedsticas f\uedsico-qu\uedmicas da madeira das esp\ue9cies Amburana cearensis (Allemao) A. C. Smithe Piptadenia stipulacea (Benth.) Ducke. Foram abatidas cinco \ue1rvores de cada esp\ue9cie, amostradas aleatoriamente no s\uedtio S\ue3o Bento, localizado no Munic\uedpio de Patos - PB. As \ue1rvores foram devidamente identificadas e transportadas para o Setor de Tecnologia de Produtos Florestais (STPF) da Universidade Federal de Campina Grande. De cada \ue1rvore, foram retirados discos pequenos (5 cm de espessura) a 0 (base), 25, 50, 75 e 100% da altura comercial do tronco (at\ue9 5 cm de di\ue2metro) e discos grandes (15 cm espessura), antes e ap\uf3s cada disco pequeno, os discos pequenos foram subdividido em quatro partes, em forma de cunha, passando pela medula. Duas cunhas opostas foram utilizadas para a determina\ue7\ue3o da densidade b\ue1sica, e as restantes foram reservadas para a realiza\ue7\ue3o das an\ue1lises f\uedsicas e qu\uedmicas da madeira e os discos maiores foram destinados \ue0 realiza\ue7\ue3o das carboniza\ue7\uf5es. A densidade b\ue1sica foi determinada de acordo com o m\ue9todo da balan\ue7a hidrost\ue1tica e para a determina\ue7\ue3o da densidade b\ue1sica m\ue9dia de cada \ue1rvore utilizou-se como fator de pondera\ue7\ue3o o volume entre se\ue7\uf5es de cada disco. Ap\uf3s a secagem ao ar, as amostras destinadas \ue0s an\ue1lises qu\uedmicas foram transformadas em serragem e feitas determina\ue7\uf5es quantitativas de extrativos total, da lignina, das cinzas, e o teor de holocelulose foi estimado por diferen\ue7a em rela\ue7\ue3o \ue0 massa inicial [100% \u2013 (teor de extrativos totais + teor de lignina + teor de cinzas)]. As amostras destinadas \ue0s carboniza\ue7\uf5es foram transformadas em cavacos, e carbonizadas em forno el\ue9trico (mufla) por 5h30min. Foram feitas determina\ue7\uf5es dos rendimentos dos produtos das carboniza\ue7\uf5es, e das propriedades f\uedsicas e qu\uedmicas do carv\ue3o vegetal. M\ue9dias significativamente superiores a 1% de probabilidade de teor de lignina, teor de holocelulose, extrativos totais e de cinzas da madeira foram encontradas para as esp\ue9cies Amburana cearensis Piptadenia stipulacea, sendo que esta \ufaltima esp\ue9cie apresentou maiores m\ue9dias de teor de lignina e teor de holocelulose. O rendimento gravim\ue9trico foi semelhante para ambas as esp\ue9cies, enquanto o rendimento em l\uedquido condensado foi significativamente superior para a Amburana cearensis. Em rela\ue7\ue3o \ue0 qualidade do carv\ue3o, foram observados maiores valores de poder calor\uedfico superior e carbono fixo para a Piptadenia stipulacea, enquanto a Amburana cearensis exibiu maiores teores de materiais vol\ue1teis e de cinzas.\u2018Caatinga\u2019 is an exclusive Brazilian biome, which features a wide variety of fauna and flora, and a good part of these are endemic varieties. Over the years, the abolition of \u2018Caatinga\u2019 by human activities has greatly reduced this biome. This fact is mainly due to the use of the energy potential of plant species without proper concern about the sustainability of it. A better understanding of the energy potential of plant species of \u2018Caatinga\u2019 enables a more appropriate management. The objective of this study was to evaluate the potential energy and the physical and chemical characteristics of wood species Amburana cearensis (Germans) A. C. Smith and Piptadenia stipulacea (Benth.) Ducke. Five trees of each species were felled, randomly sampled in \u2018S\ue3o Bento\u2019 site, located in the city of Patos, Para\uedba state. The trees were identified and transported to the Department of Forest Product Technology, Federal University of Campina Grande. From each tree, small discs were removed (5 cm thick) to 0 (base), 25, 50, 75 and 100% of the commercial height of the trunk (up to 5 cm in diameter) and large disks (15 cm thick) before and after each small disk, the small discs were divided into four parts, wedge-shaped, passing through the medulla. Two opposing wedges were used to determine the density and the rest was reserved for the physical and chemical wood analyses and the wood discs were destined for greater achievements of carbonizations. Basic density was determined according to the method of hydrostatic balance and to determine the basic density of each tree used as a weighting factor the volume between sections of each disk. After air drying, the samples for chemical analysis were transformed into sawdust and made quantitative determinations of total extractives, lignin, ash and holocellulose content was estimated by difference from the initial mass [100% - (content total extractives + lignin + ash)]. Samples intended for carbonizations were transformed into chips, and charred in an electric furnace (furnace) for 5 hours and 30 minutes. The income from the carbonization products as well as the physical and chemical properties of charcoal were determined. Averages significantly higher than 1% probability of lignin, holocellulose content, total extractives and ash wood were found for the species Amburana cearensis and Piptadenia stipulacea, and this latter had higher average lignin content and holocellulose content. The gravimetric yield was similar for both species, while the condensed liquid yield was significantly higher for Amburana cearensis. In relation to coal quality, higher values were observed for gross calorific value and fixed carbon for Piptadenia stipulacea, while Amburana cearensis exhibited higher levels of volatiles and ash
