Abstract:

It is likely more critical than ever to have access to proven indicators of the plant availability of P given the awareness of the implications of its management in crop production and the surrounding environment. Methods of assessing P availability will vary regionally, but commonly achieve good correlation to plant response. Continued improvement in the delivery of P sources to crops is in turn encouraging research that is improving our understanding of how to assess the behavior of P in soil.

Abstract:

O estudo teve como objetivos adaptar para o português e avaliar as propriedades psicométricas do Nursing Activities Score (NAS), instrumento de medida de carga de trabalho de enfermagem em UTI. Após o processo de adaptação cultural, o NAS foi aplicado em uma amostra de 200 pacientes adultos internados em UTIs. A análise da consistência interna pelo coeficiente Alfa de Cronbach revelou que o NAS possui 23 medidas independentes que não comportam consolidação ou redução. A avaliação da confiabilidade interobservadores demonstrou alta concordância (99,8%) e índice Kappa médio de 0,99. A validade concorrente foi demonstrada pela correlação estatisticamente significativa entre o TISS-28 e o NAS (r=0,67; p<0,0001), assim como pela análise de regressão multivariada (R²=94,4%; p<0,0001). Na avaliação da validade convergente, a regressão multivariada mostrou associação estatisticamente significativa entre o NAS e o SAPS II, quando ajustada pela idade (R²=99,8%; p<0,0001). Pelos resultados obtidos, o NAS mostrou-se um instrumento confiável e válido para mensurar carga de trabalho de enfermagem em UTIs brasileiras.

Abstract:

The purpose of this study was to assess the amount of ingested fluoride and the fluoride dose to which children are subjected during toothbrushing with a conventional dentifrice (1500 ppmF) and a children's dentifrice with special flavor (1100 ppmF) and evaluate the influence of rinsing and expectoration after brushing. Six brushings followed by 6 residue collections (3 per dentifrice) were performed by 42 Brazilian children (aged 20 to 30 months). The concentration of fluoride in the residues and dentifrices was determined. The amount ingested was obtained by the difference principal. 64.3% of the children did not expectorate or rinse after brushing. For both toothpastes, no significant difference was found for fluoride doses comparing children that rinsed to those that did not rinse (p³ 0.05). When children's toothpaste was used, children who did not expectorate were exposed to a higher dose than those who did expectorate (p=0.032). The same was not observed when conventional toothpaste (p=0.081) was used. In conclusion, rinsing and expectoration after brushing had no influence on the dose of fluoride to which children were exposed by use of the dentifrices. However, expectoration was directly associated to the fluoride dose when the children's dentifrice was used.

Abstract:

Guayabo del país o goiaba serrana [Acca sellowiana (Berg.) Burret] es uno de los recursos fitogenéticos subutilizados más valiosos de Uruguay y Brasil. Este árbol de fruto comestible, es endémico de una estrecha región sudamericana que abarca el noreste uruguayo y sur de Brasil, donde su cultivo se limita al uso doméstico o a pequeños huertos comerciales. El uso de los materiales de la especie se ve limitado por el desconocimiento de la diversidad presente tanto en poblaciones naturales como en materiales cultivados. El objetivo de este trabajo fue la elaboración de una lista de descriptores que permita la caracterización y evaluación de los materiales para la conservación, uso sostenible e incorporación de diversidad en los programas de mejoramiento genético. Se elaboró una lista preliminar de 41 descriptores morfo-fenológicos de hoja, flor y fruto, que se aplicó in situ a 204 individuos pertenecientes a cuatro poblaciones silvestres del noreste del Uruguay. Con el método de Máxima Verosimilitud Restringida se estimaron los componentes de la varianza entre poblaciones (s²P), entre individuos dentro de poblaciones (s²I(P)), entre muestras dentro de individuo (s²M(IP)) y sus intervalos de confianza utilizando un Modelo Lineal Mixto. Para la determinación del poder discriminante de las variables cuantitativas se adoptó como criterio estadístico la comparación de IC (límite inferior ICs²I(P)>límite superior ICs²M(IP)) y se calculó la razón entre s²I(P)/s²M(IP). Para las variables cualitativas se calculó el estadístico F para la determinación de las diferencias significativas entre individuos con el objetivo de identificar descriptores discriminantes de individuos. También se determinaron las variables que discriminan poblaciones. Se validaron siete descriptores cualitativos (forma de fruto, posición de los sépalos, color de pulpa, color interno de la cáscara, dureza de cáscara, clases de distancia estigma-estambres) y ocho descriptores cuantitativos (altura, diámetro y peso de fruto, peso de pulpa, espesor y resistencia de cáscara, distancia estigma-estambres y número de estambres) para diferenciar individuos. Se encontraron 16 variables cuantitativas y 10 cualitativas discriminantes de las poblaciones estudiadas.

Abstract:

OBJETIVO: Estimar a prevalência e os fatores associados à incapacidade funcional para atividades básicas e instrumentais da vida diária em idosos. MÉTODOS: Estudo transversal com 598 indivíduos com idade igual ou superior a 60 anos, selecionados em amostragem por conglomerado em dois estágios na cidade de Pelotas, RS, entre 2007 e 2008. Para a avaliação das atividades básicas e instrumentais foram empregados o Índice de Katz e a Escala de Lawton, respectivamente. Definiu-se como incapacidade funcional para cada domínio a necessidade de ajuda parcial ou total para a realização de, no mínimo, uma atividade da vida diária. Empregou-se a regressão de Poisson com variância robusta nas análises bruta e ajustada levando-se em consideração a amostragem por conglomerados. RESULTADOS: A prevalência de incapacidade para as atividades básicas foi de 26,8% (IC 95%: 23,0; 30,8) e a menor proporção de independência foi para controlar funções de urinar e/ou evacuar. Para as atividades instrumentais, a prevalência de incapacidade funcional foi de 28,8% (IC 95%: 24,5; 33,1), sobretudo para realizar deslocamentos utilizando algum meio de transporte. Elevado percentual de idosos (21,7%) apresentou mais de uma atividade com incapacidade nas atividades instrumentais; já nas atividades básicas, a maior parte apresentou dependência para apenas uma atividade (16,6%). Na análise ajustada, a incapacidade para as atividades básicas associou-se com cor da pele parda/preta/outras (p=0,01) e com o aumento da idade (p<0,001). Já a incapacidade para as atividades instrumentais associou-se apenas com o aumento da idade (p<0,001). CONCLUSÕES: A associação entre incapacidade funcional em atividades básicas e instrumentais com o aumento da idade é um importante indicador para que os serviços de saúde planejem ações visando prevenir ou postergar a incapacidade funcional, garantindo independência e maior qualidade de vida ao idoso.

Abstract:

This paper investigates the proportional effect of selected soil properties – low spatial variation changes are related to their local magnitudes (here standard deviation vs. mean). Content of available P, K, and Mg, and soil pH were analysed on nine agricultural fields of the Xzech Republic. Firstly, strong direct within-field proportional effect based on Moving Window Statistics (MWS) was found for soil P and K, while Mg did not exhibit any clear proportionality. Soil pH showed indication of inverse proportional effect with high field-to-field fluctuations. The relationship strength of the effect was functionally related to the asymmetry (skewness) of distribution (r = 0.31 × skew 0.08). Secondly, between-field proportional effect of 9 surveyed fields, as a measure at different scale, showed generally parallel results with the MWS approach. Proportionality is therefore not scale dependent. However, slopes of linear relationships were different for the two scales. Finally, models for prediction of proportional variogram parameters were calculated. Correlation coefficients of relationship between semivariance parameters and mean proved that sill-nugget is more stable (r = 0.74 for P and 0.83 for K) than nugget (r = 0.30 for P and 0.53 for K).

Abstract:

We are currently going through an industrial period in which connectivity, data collection of the process and its understanding to optimize it is becoming more and more common. The automotive industry is no exception as we are on the way towards connected factories where the digitization of the stamping process is a trend followed by manufacturers. A common problem often encountered is the high cost required to develop solutions by using this technology. Obtaining parameters of the manufacturing process is a challenge on many occasions. New solutions have been proposed from an opposite point of view, i.e., we evaluate what information can be extracted from the equipment and from the data obtained we can bring forward the possible tools to be developed without the need for extra investment. This article shows the verification of an experimental process, previously developed, with which we intend to find out the status of the press during the drawing process for each cycle that is carried out during production and also the status of the equipment at all times, up to the point of detecting if there is any problem both in the die and in the mechanical components of the press and verifying it with the developed tool, showing that we can know the status of the equipment by monitoring the data in real time.

Abstract:

This investigation presents the results of Hepatitis B virus screening among leprosy patients conducted in Central Brazil as a preliminary information for a HBV vaccination programme. The main objectives were to assess the seroprevalence of HBV serum markers among lepromatous patients and to analyse institutionalization as risk factor for HBV infection in this population. Two groups of lepromatous patients were studied, 83 outpatients and 171 institutionalized ones. Screening for HBV serum markers included the detection of HBsAg, anti-HBc by radioimmune assay (RIA). The prevalence of carrier state (HBsAg) was 4.8% and 8.8% among outpatients and institutionalized, respectively, (p>0.05). Seroprevalence of exposure (all markers) was statistically significant different between outpatients (16.9%) and institutionalized ones (50.3%). Institutionalized patients had an almost four fold risk of HBV infection when compared to the outpatients, and the highest risks were among patients with more than 21 years of residence in the colony, after adjusting for age and sex.

Abstract:

O objetivo desse estudo foi avaliar a utilidade do SPECT cerebral interictal na localização do foco epileptogênico em 23 pacientes do Ambulatório de Epilepsias do Hospital Universitário Clementino Fraga Filho (HUCFF/UFRJ), com epilepsia do lobo temporal (ELT) de difícil controle e tomografia computadorizada (TC) do crânio normal, estudando a correlação entre SPECT interictal, eletrencefalograma (EEG) e, em 11 casos, ressonância magnética (RM) do crânio, e comparar os resultados com os de outras seis séries da literatura. Doze (52,2%) pacientes apresentaram SPECT anormal. Entre esses, cinco (41,6% dos SPECTs anormais) apresentaram alteração unilateral ao SPECT do mesmo lado do EEG (hipoperfusão em 4 e hiperperfusão em 1), três (25% dos SPECTs anormais) apresentaram hipoperfusão bilateral ao SPECT e alterações também bilaterais ao EEG e 4 (33,3% dos SPECTs anormais) apresentaram hipoperfusão unilateral ao SPECT e EEG bilateral. A análise estatística fundamentou-se na lógica fuzzy. Os índices de correlação entre SPECT X EEG, SPECT X RM e SPECT X EEG X RM foram altamente significativos, com níveis de significância de 0,01, p < 0,0005 e intervalo de 99% de confiança em todas as correlações. Os estudos de correlação entre as séries estudadas apresentaram resultados semelhantes entre si.

Abstract:

This in vitro study compared, using computed tomography (CT), the amount of dentin removed from root canal walls by manual and mechanical rotary instrumentation techniques. Forty mandibular incisors with dental crown and a single canal were selected. The teeth were randomly assigned to two groups, according to the technique used for root canal preparation: Group I - manual instrumentation with stainless steel files; Group II - mechanical instrumentation with RaCe rotary nickel-titanium instruments. In each tooth, root dentin thickness of the buccal, lingual, mesial and distal surfaces in the apical, middle and cervical thirds of the canal was measured (in mm) using a multislice CT scanner (Siemens Emotion, Duo). Data were stored in the SPSS v. 11.5 and SigmaPlot 2001 v. 7.101 softwares. After crown opening, working length was determined, root canals were instrumented and new CT scans were taken for assessment of root dentin thickness. Pre- and post-instrumentation data were compared and analyzed statistically by ANOVA and Tukey's post-hoc test for significant differences (p=0.05). Based on the findings of this study, it may be concluded that regarding dentin removal from root canal walls during instrumentation, neither of the techniques can be considered more effective than the other.

Abstract:

Six commercial natural honeys available on the Polish market were characterised with respect to their geographical and floral origins, physicochemical parameters and microbial properties. The study focused on a determination of the activity of the main enzymes, antioxidant capacity and identification of antimicrobial effects. Fructose was the predominant sugar in all tested honeys. The largest amount of hydroxymethylfurfural (HMF) was found in eucalyptus honey. It was found that thyme honey was characterised by the highest values of diastase number, invertase activity, antioxidant capacity and total phenolic content. A very week correlation between the antioxidant properties of tested honeys and their antimicrobial action against tested bacteria was observed. M. luteus and P. putida were resistant to most honey samples. All tested honeys showed antibacterial activity against E. coli and P. myxofaciens. B. subtilis was resistant only to eucalyptus honey.

Abstract:

Relation between wheat (Triticum aestivum) nutritional status determined at the beginning of stem elongation and during anthesis, respectively, and available content of phosphorus (P-M3) and zinc (Zn-M3) determined by the Mehlich 3 extractant was studied. Both one-year pot experiment with spring wheat and two-year on-farm trials with winter wheat were run on various calcareous soils (pH values of 7.18–7.94, median 7.80, P-M3 1–289 ppm, median 54, and Zn-M3 2–14 ppm, median 4), in the Czech Republic (Central Europe). Phosphorus nutrition index (ratio of phosphorus concentration in shoot biomass to critical phosphorus concentration – Pc) was calculated using the Belanger et al.’s model: Pc = –0.677 + 0.221N – 0.00292N(2), where both phosphorus and nitrogen concentrations were expressed in g/kg shoot dry matter. Unlike phosphorus concentration in shoot biomass, phosphorus nutrition index significantly correlated with P-M3 content in soil. Optimal values of the phosphorus nutrition index were recorded if P-M3 was 51–68 ppm. Zinc concentration in shoot biomass more strongly correlated with P:Zn ratio (M3) in soil compared to Zn-M3 content in soil. P:Zn ratio in shoot biomass of 130:1 did not lead to phosphorus deficiency and corresponded to P:Zn (M3) ratio in soil of 9.3:1–14.3:1.

Abstract:

Investigations have shown that the collective motion appears not only in nucleus-nucleus but also in p-p collisions. The best tool for depicting such collective motion is relativistic hydrodynamics. In this paper, the collective motion is assumed to obey the hydrodynamic model which integrates the features of Landau and Hwa-Bjorken theory and is one of a very few analytically solvable models. The fluid is then supposed to freeze out into charged particles from a space-like hypersurface with a fixed time oftFO. The investigations of present paper show that this part of charged particles together with leading particles, which, by conventional definition, carry on the quantum numbers of colliding nucleons and take away the most part of incident energy, can give a proper universal description to the pseudorapidity distributions of charged particles measured in both nucleus-nucleus and p-p collisions at currently available energies.

Abstract:

A gradual increase of phosphorus (P) concentrations in combination with organic and mineral fertilizers was applied to clayey soils at six precise experimental field sites with different climatic conditions within the Czech Republic. Soil samples were collected after the harvest of barley. Readily available P concentrations were determined using water and 0.01M CaCl2 extractions, mobile phosphate contents were determined using the extraction procedures Mehlich 3 and Olsen. Furthermore, P uptake by barley plants was assessed. All selected procedures showed that increasing concentrations of applied P increased the mobile and readily available P contents in soils. Phosphorus uptake by barley plants ranged between 9.00 and 14.5 kg/ha and increased P application resulted in increased P concentrations in plants. Statistical analyses were performed using the Spearman test. The closest relationship was obtained for P uptake by plants and the water extraction (r = 0.81). Significant relationships were also obtained for plant uptake and the Mehlich 3 and CaCl2 methods (r = 0.40 and 0.36, respectively). There was no statistical dependence between P uptake and the Olsen method (r = 0.25). Regression analysis was expressed best as linear regression. The closest relationship was found for water extracts and P uptake by plants (with a determination coefficient of 65%). Determination coefficients for P uptake and other methods used were significantly lower (max. 20%).

Abstract:

Fiber-reinforced cementitious matrix (FRCM) composites are largely employed in Italy to improve the mechanical behavior of masonry members. Many different matrices and fiber textiles are available on the market, which entails for a large number of available composites, each with peculiar mechanical and physical properties. Among the possible applications, FRCM are often externally bonded to masonry walls to increase the wall shear capacity or to prevent possible wall out-of-plane failure. Up to date, only two guidelines are available for the design of FRCM strengthened masonry members, namely the American ACI 549.6R and the Italian CNR-DT 215. In the Italian guideline, the bending strength of an FRCM strengthened masonry wall is associated with the performance of the composite - which is investigated by FRCM coupon tensile tests and FRCM-masonry joint bond tests - through a cross-sectional equilibrium that assumes perfect bond among each material.In this paper, a database comprising 90 experimental tests on FRCM-strengthened masonry walls subjected to out-of-plane loading is collated from the available literature. The experimental results are used to compute the composite effective strain, which is then compared with the corresponding composite maximum strain obtained by characterization tests according to the CNR-DT 215 procedure. The comparison sheds light on the role of coefficients employed in the analytical procedure and helps understanding the influence of the FRCM on the wall bending capacity.

Abstract:

The suitability of ion-exchange resin extraction for assessing biologically available P (phosphorus) concentrations was evaluated in a wide range of water samples of different origins (natural waters, wastewater treatment plant effluents, and industrial effluents). A recycling system was specifically designed to enhance P adsorption by the resin by maintaining a steep P gradient. Resin extractable P compared favorably with total P, total soluble P, and soluble reactive P, as a predictor of bioassay available P (BAP). Biologically available P was generally greater than soluble reactive P and less than total soluble P. Over the diverse water samples tested, the best model for predicting BAP used resin extractable P and soluble reactive P.

Abstract:

The investigation is focused on the illustration of the temporal changes in spatial variability of the Mehlich III available phosphorus, potassium and magnesium in the 10.5 hapart of the whole 54 hafield, located near Český Brod. Soil is characterized as Orthic Luvisol. To estimate temporal variability of available nutrients, soil samples were taken in 2001–2003 four times per year (twice in spring and twice in the autumn periods). For the description of field variability of selected soil parameters coefficient of variation (CV), experimental variograms with fitted models and relative nugget effect parameters have been used. Three year results shows that the lowest temporal variability, characterized by relative nugget effect had available Mg (4–23%) and P (13–29%) and K (15–49%).

Abstract:

The P-supplying power of the fine-textured soils from Abitibi-Temiscaming (Quebec, Canada) has never been investigated. Anion exchange membranes (AEM), the electro-ultrafiltration (EUF) technique and chemical extractions were used to describe their P status. Phosphorus was desorbed from four soils that had received 52.4 kg P ha–1 yr–1 from 1994 to 1996 and from unfertilized soils. The cumulative amount of P desorbed in 75 min by EUF from unfertilized soils varied from 10 to 69 mg P kg–1. Averaged over all sites and treatments, the amount of soil P extracted by different methods ranged from 1.0 to 18.9 mg P kg–1. The cumulative grass P uptake was significantly related to P desorbed by all methods (0.39 < r < 0.84). A close relationship between grass P uptake and PAEMs indicated the adequacy of the AEMs to determine plant-available P in Abitibi-Temiscaming soils. A high degree of linearity (0.97 < R2 < 0.99) of the EUF-P desorption curves at 200 V and 20°C with time was obtained. This indicates that soils have a high capacity to buffer removal of P from soil solution with reserve P. The EUF technique has shown that these soils hold very large inorganic P reserves and this may explain the lack of grass response to P fertilizers. Key words: Anion exchange membranes, grass-P uptake, P-desorption, Mehlich3-P, Olsen-P.

Abstract:

Soil available phosphorus (P), a major plant nutrient, exhibits a high degree of spatial variability. Spatial variability assessment of P is necessary for its precise management using geostatistics. Therefore, the present study was conducted in an intensely cropped region of Ladian village of Ludhiana, Punjab during 2014-2016 to assess the spatial variability status of P under three prevalent land use systems, viz. berseem-based land use, rice-wheat system and poplar-wheat based agroforestry system. The classical statistics showed the variability of available-P in terms of percent coefficient of variation (%CV), but unable to distinguish variability between rice-wheat (CV=38.79%) and poplar-wheat system (CV=38.58%). Lower variability was observed in berseem-based land use (CV=15.21%), though the mean available-P content (46 kg/ha) was higher in this land use. However, the geostatistical techniques successfully demonstrated the spatial dependence of P within and in between land uses using nugget-sill (NS) ratio. Gaussian model was found suitable for describing the spatial structure of available-P under berseem-based land use; while, Exponential models were found suitable for rice-wheat and poplar-wheat systems. The value of NS ratio of available-P was 0.17 for poplar-wheat based land use, suggesting strong spatial dependence, whereas the rest other land uses exhibited moderate (NS=0.74) to weak (NS=0.82) spatial dependence of available P. The spatial variability maps of P were generated using ordinary kriging technique, demonstrated significantly the higher variability of P in poplar-wheat system than other systems. This variability should be considered before applying phosphatic fertilizers to this land use to get optimum response. The generated maps would assist the farmers for site-specific P management in the study area.

Abstract:

Background. Transfascial suture passers (TSPs) are a commonly used surgical tool available in a wide array of tip configurations. We assessed the insertion force of various TSPs in an ex vivo porcine model. Methods. Uniform sections of porcine abdominal wall were secured to a 3D-printed platform. Nine TSPs were passed through the abdominal wall both without and with prolene suture under the following scenarios: abdominal wall only and abdominal wall plus underlay ePTFE or composite ePTFE/polypropylene mesh. Insertion forces were recorded in Newton (N). Results. When passed without suture through the abdominal wall, smaller diameter TSPs required less insertional force (1.50 ± 0.17 N vs 9.68 ± 1.50 N [ P = 0.00072]). Through composite mesh, the solid tipped TSPs required less force than hollow tipped ones (3.87 ± 0.25 N vs 7.88 ± 0.20 N [ P = 0.00026]). Overall, smaller diameter TSPs required less force than the larger TSPs when passed through ePTFE empty (Gore 2.95 ± 0.83 N vs Carter-Thomason 16.07 ± 2.10 N [ P = .0005]) or with suture (Gore 8.37 ± 2.59 N vs Carter-Thomason 19.12 ± 1.10 N [ P = .003]). Conclusions. Diameter plays the greatest role in the force required for TSP penetration. However, when passed through underlay mesh or while holding suture, distal tip shape, the mechanism of suture holding, and shaft diameter all contribute to the forces necessary for penetration. These factors should be considered when choosing a TSP for intraoperative use.

Abstract:

Based on a greenhouse experiment, we evaluated nitrogen availability in the surface mineral layer of soil under various deciduous forest stands by analysing the following soil characteristics: total organic C, total N, initial content of easily available N inorganic forms, mineralized N content obtained by aerobic and anaerobic incubations and A-value. The experiment was performed on a test plant and through the application of urea enriched with 5.4% 15N. The studied forest soils are characterized by high mineralization intensity and high N availability indices. Aerobic incubation appears to be the most appropriate method for evaluating the available N content. The amounts of mineralized and nitrified N, obtained by aerobic incubation, with subtraction of the initial content of available mineral N forms are in correlation (P ≤ 0.05) with total organic C content (r = 0.916) and total soil N (r = 0.903) while the correlation with the C/N ratio is poor (r = 0.645).

Abstract:

Some crop species could be used inside a cropping system as part of a strategy to increase soil P availability due to their capacity to recycle P and shift the equilibrium between soil P fractions to benefit the main crop. The release of P by crop residue decomposition, and mobilization and uptake of otherwise recalcitrant P are important mechanisms capable of increasing P availability and crop yields.
