Abstract: the culture of the dwarfed coconut palm has been growing in the ceará state (brasil) as a response of the growing demand for this product by the great industries. the objective of the present study was to evaluate the effects of nitrogen and potassium fertilizer rates on the number of female flowers, fruits, coconut clusters, fruit weight, coconut water content and obrix, in a plantation of dwarfed coconut palm ?an?o verde de jiqui? with 4 year old plants, applied via fertigation in a soil of the littoral region of the state of the ceará. the experiment was conducted in a soil classified as neossolo quartzarênico dystrophic in the period between january and december of 2003. the statistical design was a randomized block with 4 replications consisted of combination of 5 rates n and 5 ones of k. with exception to the number of coconut clusters, all variables were higher than the production averages with relation to determined applied rate. the most significant results, in terms of maximum production responses, were related to the variables number of female flowers, coconut clusters, fruits, and obrix, where the treatment with 2.10 kg n and 3.50 kg k per plant and year might be the optimal one for all studied variables.

Abstract: El cultivo de coco variedad An o viene creciendo en el Estado de Ceará (Brasil) como respuesta a la creciente demanda de este producto por las grandes industrias. El objetivo del presente estudio fue evaluar los efectos de dosis de nitrógeno y potasio sobre el número de flores femeninas, de frutos, de racimos, peso del fruto, volumen de agua del coco y sólidos solubles (oBrix), en palmas de coco variedad An o verde de Jiqui, con 4 a os de edad, aplicadas bajo fertirrigación en un suelo litoral. El trabajo fue desarrollado en un suelo Neossolo Quartzarênico distrófico en el período de enero a diciembre de 2003. El dise o experimental utilizado fue de bloques aleatorios, con 4 repeticiones, considerando 5 dosis de N y 5 de K combinadas. Con excepción del número de racimos por palma, los otros parámetros estudiados mostraron valores superiores de producción, en relación con la dosis aplicada. Los resultados más significativos, con relación a la máxima eficiencia de respuesta, para las variables número de flores femeninas, de fruto, peso del fruto, volumen de agua del coco y sólidos solubles totales, tuvo el tratamiento con 2,10 kg N y 3,50 kg K por planta y a o que parece ser la dosis óptima en todas las variables analizadas.

Sidney Pereira Pinto Lemos, Patrícia Veruska Ribeiro Barbosa Lemos, Natália Araújo Lima Rocha Coelho, Danielle Moreira de Abrêu, Lucas Barbosa Ribeiro Feitosa
Case Reports in Clinical Medicine (CRCM) , 2015, DOI: 10.4236/crcm.2015.43025
Introduction: Advances in prenatal imaging studies have allowed early diagnosis of Congenital Diaphragmatic Hernia (CDH), although neonatal mortality remains at high levels (60% survival). Despite advances, this study found delayed diagnosis, demonstrating subdiagnosis, possibly caused by lack of resources and/or prenatal diagnostic failure. Case Report 1: Infant, 4 months and 22 days old, dyspneic, cyanotic, with fever and vomiting for 3 days, treated as pneumonia. After the second chest radiography, a right CDH was revealed. Surgical correction was performed and removal of Meckel’s diverticulum was surgical findings. The patient was discharged on the 10th days after admission. Case Report 2: Infant, 11 months and 3 days old, distended abdomen, with fever and dyspnea for 2 days, treated as pneumonia. After the second chest radiography, a left CDH was revealed. The patient was submitted to surgery, intestinal loop incarceration without necrosis was observed, and the correction of CDH was performed. The patient was discharged on the 7th day after admission. Discussion: Three cases, between July 2012 and July 2013, were diagnosed at Dom Malam Hospital; 2 Cases of CDH, with delayed diagnosis, showed incidence of 66.66%. Delayed diagnosis of these patients with initial hypotheses of pneumonia demonstrated high risk, emphasizing the importance of diagnosis research through observation of the clinical course, the correct imaging interpretation, in order to establish early diagnosis and treatment.

Abstract: this taxonomic treatment of the genus solanum is part of the "flora da paraíba" project which aims to identify and catalogue the species of the local flora. botanical collections, field observations and morphological studies were done for identification, description and botanical illustration of the plant species, also supported by the literature and analysis of brazilian and foreign herbaria, plus specimens from ean and jpb herbaria. twenty two species of solanum were recorded in the state of paraíba: solanum agrarium sendtn., s. americanum mill., s. asperum rich., s. asterophorum mart., s. caavurana vell., s. capsicoides all., s. crinitum lam., s. jabrense agra & m.nee, s. melissarum bohs, s. ovum-fringillae (dunal) bohs, s. palinacanthum dunal, s. paludosum moric., s. paniculatum l., s. paraibanum agra, s. polytrichum moric., s. rhytidoandrum sendtn., solanum sp., s. stagnale moric., s. stipulaceum roem. & schult., s. stramoniifolium jacq., s. swartzianum roem. & schult. and s. torvum sw. three species are new records for paraíba: s. ovum-fringillae, solanum sp. and s. swartzianum.

Abstract: in this paper we report a theoretical study aiming to revisit the origin of the preferential π-π stacking conformation of the (+)-8-phenylmentyl acrylate (2). for this, we have applied several dft and ab initio methods to calculate local minimum geometries, vibrational frequencies, thermochemical properties and 1h nmr chemical shifts for 2 and the model compound 3-phenylpropyl acrylate (3). we have observed that the mpw1b95 functional was the most suitable method to explain 1h nmr experimental data which show the stacking conformation of 2 (2s) is more stable that trans conformation (2t) and the stacking conformation of 3 (3s) is less stable that trans conformation (3t). after that, geometrical and energetic features of the intermolecular complex benzene...methylacrylate (4) have also been studied using mpw1b95 method. from our results, we have noticed that both steric and dispersion effects play a key role in the conformational equilibrium of 2.

Abstract: soil variability occurs due to natural and anthropogenic factors acting at various spatial and temporal scales. the purpose of this study was to evaluate the spatial variability as well as the relation of some chemical attributes using different statistical techniques. the study was conducted in the municipality of maracanaú (ce, brazil) in the commercial area of sugar cane in a typic hapludalf. soils were sampled in a 100 x 100 m grid every 10 m and at a depth between 0 and 20 cm for determination of exchangeable acidity, ph (kcl), ca, na, k, mg, p, n, sum of bases, cationic exchange capacity, base saturation and organic matter. data were subjected to analysis of descriptive statistics, multivariate analysis and geostatistics. attributes showed low and medium variability, except for ph that did not show spatial dependence. different statistical tools helped to identify the soil spatial variability and to get a better understanding of relationships among different attributes. techniques also allowed to better plan and control agricultural production, especially in carrying out site specific management of agricultural inputs.

Revista Brasileira de Farmacognosia , 2012,
Abstract: The essential oil (EO) of aerial parts of Lantana camara L., Verbenaceae, from Sim es, Piaui, Northeast of Brazil, were obtained by hydrodistillation and analyzed by GC-FID and GC-MS techniques. In total, 68 compounds were identified. The most representative compounds of the oil were mono and sesquiterpenes. The main compounds found in the oil of the leaves in different months were β-caryophyllene (10.5%, in June of 2009), sabinene (7.98%, in September of 2008), limonene (7.68%, in September of 2008), spathulenol (11.64%, in September of 2008). The oil from stems of L. camara was characterized by a largest amount of sesquiterpenoids, with spatulenol (15.9%) and caryophyllene oxide (17.1% in June of 2009), as main components. β-Gurjunene (32.7%, in September of 2008) was the most prominent compound in the stems oils, which was absent or at very low relative abundance in leaves. L. camara essential oils from leaves were cytotoxic to V79 mammalian cells and also to Artemia salina, showing 50% lethal concentration (LC50) values from 0.23 μg/mL. The in vitro data obtained in this study suggested that EO may also be effective treating yeast infection in patients infected with fluconazole and terbinafine resistant isolates, but its toxicity must be monitored carefully.
