Influence of Water Vapor on the Adsorption of VOCs on Lignin‐Based Activated Carbons

Abstract Activated carbons with a wide range of burn‐off degrees obtained from Eucalyptus kraft lignin have been used to study the influence of the presence of water vapor on VOCs adsorption. The amount adsorbed and the rate of adsorption of both benzene and water vapor increase with activated carbon burn‐off as a consequence of an increase of micropore volume, broadening of micropore size distribution and increasing development of meso‐ and macroporosity. Similar results were found for MEK and methanol. Benzene is only partially desorbed at the adsorption temperature and an appreciable amount of it remains in the carbon, most likely in the narrow micropores. On the contrary, water vapor is completely desorbed at the adsorption temperature and its adsorption profile clearly exhibits two steps with different adsorption rates, associated to water molecules adsorbed on the active sites given rise to cluster formation and further migration and filling of the micropores. Adsorption with mixtures of VOC and water vapor has been carried out. The total amount adsorbed by the carbon, near the equilibrium point, is higher than in the case of the stream containing only the VOC. The adsorption rates for the mixtures streams are similar to that for the corresponding streams containing only the VOC in the case of carbons with a well developed porous structure. However, the presence of water vapor increases the rate of adsorption on the activated carbons with narrower microporosity. Saturation of the activated carbon with water vapor prior to the adsorption of a mixture containing benzene and water vapor has shown little effect on the amount of benzene adsorbed, suggesting that water and benzene molecules are adsorbed in different sites on the carbon surface.
Evaluation of the Sanitary Conditions of Head Meat, Esophagus, Diaphragm Meat, and Boning Scrap Processing

Enterobacteriaceae, coliforms, and Escherichia coli counts are important hygiene indicators and may be pathogenic. Thus, the aim of the present study was to determine microbiological contamination in head meat, the esophagus, diaphragm, and boning scraps and evaluate the hygienic conditions of the processing of these products. The Petrifilm® (3M) method for determining Enterobacteriaceae, total coliforms, and E. coli was applied for 104 samples. APHA, European Union, PAHO/WHO, and Brazil/MAPA recommendations were followed. Bleeding and skinning knives were contaminated with E. coli (61.5%). Regarding the meat cuts, 30.76% samples from head meat, the esophagus and the boning flap showed the presence of E. coli in counts up to 2 log CFU/g, while 15.3% of the diaphragm samples showed up to 1.85 log CFU/g. The analyzed comminuted meat was, therefore, shown to be contaminated with E. coli during processing, indicating that end-products from this raw material can offer biological risks.
Dextran-Polyacrylamide as Matrices for Creation of Anticancer Nanocomposite

Drug targeting to specific organs and tissues is one of the crucial endeavors of modern pharmacotherapy. Controlled targeting at the site of action and reduced time of exposure of nontargeted tissues increase the efficacy of the treatment and reduce toxicity and side effects, improving compliance and convenience. Nanocarriers based on the branched copolymers dextran-graft-polyacrylamide were synthesized and characterized and were tested on phagocytic cells. It was shown that these nanoparticles are actively captured by phagocytic cells and that they are not cytotoxic. The polymer nanoparticles loaded with cisplatin at different concentrations from 0.1 to 10 μg/mL yielded dose-dependent decrease in viability of chronic myelogenous leukemia and histiocytic lymphoma cells. The lowest percentage of viable cells was observed for lymphoma cells (22%). Taking into account the fact that our nanoparticles will act mainly on malignant phagocytic cells and do not affect healthy cells, they can thus potentially be used for the therapeutic treatment of tumor cells having phagocytic activity. The effect of nanosilver on cell viability was lower than the one of polymer/cisplatin composite. The data from the cytotoxic studies indicate that nanosilver induces toxicity in cells. However, when the copolymers were conjugated to both nanosilver and cisplatin, such a nanosystem displayed less cytotoxic effect compared to the conjugates of dextran-polyacrylamide and cisplatin.
Orbits for 18 Visual Binaries and Two Double-line Spectroscopic Binaries Observed with HRCAM on the CTIO SOAR 4 m Telescope, Using a New Bayesian Orbit Code Based on Markov Chain Monte Carlo

We present orbital elements and mass sums for 18 visual binary stars of spectral types B to K (five of which are new orbits) with periods ranging from 20 to more than 500 yr. For two double-line spectroscopic binaries with no previous orbits, the individual component masses, using combined astrometric and radial velocity data, have a formal uncertainty of . Adopting published photometry and trigonometric parallaxes, plus our own measurements, we place these objects on an H-R diagram and discuss their evolutionary status. These objects are part of a survey to characterize the binary population of stars in the Southern Hemisphere using the SOAR 4 m telescope+HRCAM at CTIO. Orbital elements are computed using a newly developed Markov chain Monte Carlo (MCMC) algorithm that delivers maximum-likelihood estimates of the parameters, as well as posterior probability density functions that allow us to evaluate the uncertainty of our derived parameters in a robust way. For spectroscopic binaries, using our approach, it is possible to derive a self-consistent parallax for the system from the combined astrometric and radial velocity data (“orbital parallax”), which compares well with the trigonometric parallaxes. We also present a mathematical formalism that allows a dimensionality reduction of the feature space from seven to three search parameters (or from 10 to seven dimensions—including parallax—in the case of spectroscopic binaries with astrometric data), which makes it possible to explore a smaller number of parameters in each case, improving the computational efficiency of our MCMC code.
Selection of solvents for extrative destillation of ethanol

Biofuels have been an important subject of study, mainly because of petroleum scarcity. Bioethanol is the most used biofuel as alternative to petrol, but the purification cost is high and in order to use bioethanol mixed with hydrocarbons, it needs to be 99.5 % pure. Alternatives for solvents to be used in ethanol’s extractive distillation are being investigated. The ionic liquids are seen as a solution to many of the problems in the chemical industry in the near future, due to their excellent properties. The purpose of this dissertation is to study the behavior of different ionic liquid – ethanol or water systems. This has been achieved through the study of two systems by ebulliometry: 1-butyl-3-methylimidazolium chloride and choline chloride at three different pressures. Finally using COSMO RS, the modeling of the experimental data was made. Are also discussed several factors that influence the behavior of those systems.
Restart Strategies for Constraint-Handling in Generative Design Systems

Product alternatives suggested by a generative design system often need to be evaluated on qualitative criteria. This evaluation necessitates that several feasible solutions which fulfill all technical constraints can be proposed to the user of the system. Also, as concept development is an iterative process, it is important that these solutions are generated quickly; i.e., the system must have a low convergence time. A problem, however, is that stochastic constraint-handling techniques can have highly unpredictable convergence times, spanning several orders of magnitude, and might sometimes not converge at all. A possible solution to avoid the lengthy runs is to restart the search after a certain time, with the hope that a new starting point will lead to a lower overall convergence time, but selecting an optimal restart-time is not trivial. In this paper, two strategies are investigated for such selection, and their performance is evaluated on two constraint-handling techniques for a product design problem. The results show that both restart strategies can greatly reduce the overall convergence time. Moreover, it is shown that one of the restart strategies can be applied to a wide range of constraint-handling techniques and problems, without requiring any fine-tuning of problem-specific parameters.
Optimization of a protocol for extraction of Plasmodium falciparum RNA from infected whole blood samples for use in DNA microarrays

This study was carried out to determine the efficiency of two reagents, RNAlater and RNAwiz, for their ability to stabilize Plasmodium falciparum RNA in infected whole blood and saponin lysed parasite pellets for use in DNA microarrays. Eight infected blood samples were stored in each of the reagents, and RNA extracted at days 0 and 56 post collection. RNA yields and quality were compared at the different time points between the two test reagents. We show that for both reagents, higher RNA yields and quality is obtained when RNA is isolated immediately after sample collection (day 0), however, results show that RNAwiz storage provides a marginally higher RNA yield compared to RNAlater storage. Our results indicate that whole blood gave slightly higher RNA yields with superior quality as compared to saponin lysed samples when such whole blood samples are stored in RNA wiz, but not in RNAlater. From our results, we recommend RNAwiz as a better reagent for use in storage of whole infected blood intended for extraction of P. falciparum RNA for DNA microarrays and other sensitive techniques.
Clonehenge: an experiment with gridded and non-gridded survey data

This is a report of hirther work investigating methods of survey and of presentation of topographical data from archaeological sites. It continues on the theme of two papers given at the 1987 Computer and Quantitative Methods in Archaeology conference which were concerned with graphical methods of data presentation (Spicer 1988) and a series of experiments to quantify the 'quality' of surveys done on grids (Fletcher & Spicer 1988b). The main purpose of this paper is to introduce a versatile simulated archaeological site on which the work mentioned above may be tested. It can also be the subject of many other experiments concerned with the manipulation of topographical data. Although we describe some very preliminary experiments performed on this model these are not to be considered as complete, merely a starting point for considerably more detailed work, both by us, and, we hope, by others. A computer generated 'site' is by no means a new idea: Scollar simulated a doubleditched Roman fort as a rectangular magnetic anomaly (Scollar 1969) which was generated along with the noise and degeneration normally met with during geophysical surveying. Our simulation is more immediately recognisable by the archaeologist, for it consists of a collection of earthworks visible (so far! ) only as surface features. The site, known as 'Clonehenge', may be 'surveyed' by any means and at any resolution, since the data is produced from a function, written in C, with all the mathematics needed for the heights of an infinite number of points on the model's surface. A listing is to be published elsewhere (Fletcher & Spicer 1988a) so as to permit others to compare results using the same reference standard. The archaeological simulation is based very broadly (and with apologies to it) on Arbor Low, in Derbyshire. Clonehenge is a class II henge, with perfectly circular ditch and bank, separated by a narrow berm. The entrances are not exactly opposing; they are
Propagation of Pecan (Carya illinoensis): A review

The Pecan (Carya illinoensis) is the most important species that belongs to the Carya genus. It is cultivated mainly for its nut, which is rich in oils and proteins, and for its good quality wood. Pecan is conventionally propagated by budding or grafting onto rootstocks obtained by open pollination. However, these techniques are not very efficient due to low propagation rates, poor survival and difficult establishment. Therefore, in vitro propagation of pecan can play a very important role in rapid multiplication of cultivars with desirable traits and production of healthy and disease-free plants in a short time. In the present review, the improvements over the years in the propagation of pecans, the refinements of protocols for obtaining high shoot multiplication and regeneration through organogenesis and/or somatic embryogenesis is discussed. Some basics of genetic transformation and its possible benefits are also discussed. Key words: Pecan, in vitro root induction, shoot multiplication, regeneration, micropropagation, somatic embryogenesis, genetic transformation.
Phytoextraction: Using Brassica as a Hyper Accumulator

Phytoextraction is a cost-effective method that could be an alternative to remediate polluted sites. Growth performance, biochemical, enzymatic activity, accumulation, translocation and mobility of arsenic form soil to root and leaves were studied in co-cultivated hyper accumulator (Brassica juncea) and hypo accumulator (Abelmuscus esculentus) at various levels of arsenic. B.juncea accumulated fourfold and fivefold arsenic in roots, shoots and leaves, respectively than Abelmuscus esculentus L. A. esculentus seedlings when cultivated alone were seen sensitive to arsenic with decrease growth, poor values of accumulation factor, translocation factor and mobility of metal. But the same plant when cocultivated with Brassica juncea there is no toxicity symptoms and reduction of growth, values of Accumulation factor, translocation factor and mobility of metal. This is well understand that Brassica juncea showing higher accumulation of nickel, more translocation of arsenic from root to shoot and good mobility of arsenic was increased form level 1 to level 3, It was revealed that the accumulation of arsenic was more in root and shoot of B. juncea than A. esculentus. It is inferred from the present study that A. esculentus is a hypo accumulator and is sensitive to arsenic. When co-cultivated with Brassica juncea showing less of metal toxicity because Brassica juncea being hyper accumulator of arsenic, accumulate more metal and save Abelmuscus esculentus.
Forage yield and grazing efficiency on rotationally stocked pastures of 'Tanzania-1' guineagrass and 'Guaçu' elephantgrass

The potential carrying capacity of tropical pastures depends not only on the productivity of the forage species and the amount of forage on offer, but also on the efficiency with which the produced herbage is harvested by the grazing animal. This study was conducted to assess the yield and grazing efficiency on 'Guacu' elephantgrass (Pennisetum purpureum Schum.) and 'Tanzania-1' guineagrass (Panicum maximum Jacq.) pastures under rotational stocking. Forage accumulation, daily accumulation rates, grazing losses, bulk density, and utilization efficiency were measured. Treatments (forages) were replicated four times in a completely randomized design. Total forage dry matter (DM) yield over 214 days of grazing were 23850 and 15000 kg ha -1 , for the elephantgrass and the guineagrass, respectively, using 250 kg N ha -1 in split applications after each grazing. Mean forage accumulation per grazing cycle was 7950 and 5010 kg ha -1 and mean daily accumulation rates were 137 and 86 kg -1 ha -1 d -1 for P. purpureum and P. maximum, respectively. Grazing losses per cycle averaged 1040 and 880 kg ha -1 , for grazing efficiencies of 52 and 37% for the Pennisetum and the Panicum, respectively. Mean seasonal stocking rate was 5.1 AU (animal unit = 500 kg LW) per ha on P. purpureum and 3 AU ha -1 on P. maximum pastures. For both species, productivity potential resides on the high pasture carrying capacity, particularly when there are no soil fertility limitations during the warm/rainy season. Based on growth potential and stem elongation characteristics, 'Guacu' requires better management skills and 'Tanzania-1' has a more pronounced seasonal growth, as expressed by seasonal yields, apparently due to their contrasting responses to temperature and daylength.
Regeneration: an overlooked aspect of trait‐based plant community assembly models

Despite the disproportionate influence that propagule production, dispersal, seed‐to‐seedling recruitment and vegetative reproduction can have on plant population and community dynamics, progress has been slow in the directed collection of regeneration traits to inform community assembly outcomes. While seed mass is globally available and linked to growth and reproductive output, there are limits to its explanatory ability. In this essay, we call for expanded efforts to integrate a more diverse set of regeneration traits into community assembly models. First, we extend an existing community assembly framework to conceptualize regeneration as a series of transitional processes whose outcomes are influenced by abiotic filters, biotic interactions and species traits. We then briefly review the literature, highlighting filters and traits of demonstrated or theorized importance for each transition. Finally, we place regeneration in the context of existing and emerging modelling approaches in trait‐based community assembly, summarizing key areas of progress needed to integrate regeneration traits into these efforts. Synthesis. By incorporating influential regeneration traits into empirical studies and global data bases, we can begin to disentangle regenerative mechanisms underlying community assembly outcomes and enhance rapidly developing models of species’ abundances, distributions and responses to environmental change.
Whole-Body Breathing III: Clinical Application/Implementation

Abstract This article is the third in a three-part series on whole-body breathing. The author proposes a process model, in which breath training, muscle relaxation, and lifestyle changes are customized as the therapist explores the patient's response to initial interventions. This process model is useful for many cases in medical practice, where clear and specific causes cannot be identified for symptoms and no clear treatment is known. The article provides a case history of a 38-year-old man who sustained whiplash injuries in a motor vehicle accident and subsequently developed cardiovascular problems (congestive cardiomyopathy). Subsequent cardiac rehabilitation proceeded poorly, but he responded positively when the whole-body breathing approach was added, with improved ejection fraction and improved tolerance for activity. This case study illustrates the process of adjusting interventions to the individual's condition.
Monte Carlo integration with a growing number of control variates

Abstract It is well known that Monte Carlo integration with variance reduction by means of control variates can be implemented by the ordinary least squares estimator for the intercept in a multiple linear regression model. A central limit theorem is established for the integration error if the number of control variates tends to infinity. The integration error is scaled by the standard deviation of the error term in the regression model. If the linear span of the control variates is dense in a function space that contains the integrand, the integration error tends to zero at a rate which is faster than the square root of the number of Monte Carlo replicates. Depending on the situation, increasing the number of control variates may or may not be computationally more efficient than increasing the Monte Carlo sample size.

Expression of WRKY and MYB genes during infection with powdery mildew in cucumber ( Cucumis sativus L)

The expression change pattern of three transcription genes ( WRKY30, WRKY6 and MYB ) in two cucumber lines with different powdery mildew resistance (resistant line ‘JIN5-508’ and susceptible line ‘D8’) were investigated during the infection process with powdery mildew using real-time quantitative polymerase chain reaction (RT-PCR). Gene expression analysis during different time points revealed that the expression ratio of WRKY30 was 10.08585 in D8 and 5.117667 in JIN5-508, respectively, and for WRKY6, the expression ratio was 5.396152 in D8 and 3.787322 in JIN5-508, respectively, and for MYB, the expression ratio was 14.17324 in D8 and 10.70195 in JIN5-508, respectively. Additionally, the time point of the highest relative expression ratio for the three genes was different in the two cucumber lines according to their resistance to powdery mildew, whereas the susceptible line D8 was earlier than the resistant line JIN5-508 in responding to the powdery mildew infection. We suggest that the three genes’ expressions induced by powdery mildew pathogen is related to the disease resistance, and the response of susceptible line is earlier and higher than the resistant line, which may have interactions between the three genes and other resistant genes. Key words : Cucumber, powdery mildew, gene expression pattern.
Large intraslab earthquake (2011 April 7, M 7.1) after the 2011 off the Pacific coast of Tohoku Earthquake (M 9.0): Coseismic fault model based on the dense GPS network data

We propose a source fault model for the 2011, April 7, earthquake (M 7.1) deduced from a dense GPS network. The coseismic displacements obtained by GPS data analysis clearly show the spatial pattern specific to intraslab earthquakes, not only in the horizontal components but also the vertical ones. A rectangular fault with uniform slip was estimated by a non-linear inversion approach. The results indicate that the simple rectangular fault model can explain the overall features of the observations. The amount of moment released is equivalent to Mw 7.17. The hypocenter depth of the main shock estimated by the Japan Meteorological Agency is slightly deeper than the neutral plane between down-dip compression (DC) and down-dip extension (DE) stress zones of the double-planed seismic zone. This suggests that the depth of the neutral plane was deepened by the huge slip of the 2011, M 9.0, Tohoku Earthquake, and the rupture of the thrust M 7.1 earthquake was initiated at that depth, although more investigations are required to confirm this idea. The estimated fault plane has an angle of ∼60 degrees from the surface of the subducting Pacific plate. It is consistent with the hypothesis that intraslab earthquakes are thought to be a reactivation of the pre-existing hydrated weak zones produced in the bending process of oceanic plates around outer-rise regions.
