An Enhanced and Efficient Multi-View Clustering Trust Inference Approach by GA Model
Authors: Ravichandran M  , Subramanian K M  , Jothikumar R
Published: August 2019

Multi-view affinity propagation (MAP) methods are widely accepted techniques, measure the within-view clustering and clustering consistency. These suffer from similarity and correlation between clusters. The trust and similarity measured was introduced as a new approach to overcome the problem. But these approaches suffer from low accuracy and coverage due to avoidance of implicit trust. So, a framework called multi-view clustering based on gray affinity (MVC-GA) created by integrating both similarity and implicit trust. Similarity between two clusters is obtained by applying the Pearson Correlation Coefficient-based similarity. It utilizes the collaborative filter-based trust evaluation for each clustered view in terms of the similarity based on the gray affinity nn algorithm. Classification of incomplete occurrences is addressed based on GA Function. Experiments on the benchmark data sets have been performed to validate the proposed framework. It is shown that MVC-GA can improve the multi-view clustering accuracy and coverage.
How Knowledge Management Influences Performance?
Authors: Joshi Himanshu , Chawla Deepak
Published: August 2019

Prior research studies on knowledge management (KM) offer inconsistent support that it enhances firm performance. A majority of them discuss KM without incorporating the valuation of KM efforts. This article proposes a conceptual model comprised of six KM and two performance constructs. Performance is classified as financial and non-financial. Survey data from 313 Indian respondents is used to examine the influence of KM on firm performance. The results show that there is a strong, positive and significant link between the six KM constructs and organizational performance. Further, it is found that the influence of KM constructs on financial performance is indirect, that is, their influence is accomplished through the mediating variable organizational performance. The study provides evidence, firstly, through identifying important KM constructs and secondly by examining its influence on performance. It contributes to managerial practice by proposing an empirically validated KM model, which can guide KM practitioners in developing capabilities for enhancing organizational performance.

Published: August 2019

The membrane gas separation is currently a competitive separation process. The heart of the membrane gas separation process is the membrane, more precisely the material from which it is made. The search for a selective material to develop a gas separation membrane is an important task presently. Membrane materials with advantageous impact of sorption transport component is a good material for the selective fractionating С1-С4 hydrocarbons with obtaining methane fraction and C3+ fraction. Such materials are polyalkylenesiloxanes. In this work, the optimal concentration of a curing agent (tetraethoxysilane) was defined (5%). Such concentration is necessary for obtaining constant membrane film with high gas transport properties: the permeability coefficient for n-butane is 7400; the ideal selectivity of n-butane/methane is 25.5.

Published: August 2019

In the present work, a study was conducted for the first time on the modification of hollow fiber UF PSF membranes by cellulose nanofibrils. Two approaches to membrane modification were analyzed: 1) introduction of CNF into the molding solution; 2) additions of CNF to the internal coagulant. Analysis of the transport properties of the investigated membranes showed that the first approach allows increasing the porosity of hollow fiber PSF membranes, due to which the permeability increases from 82 to 287 l / m2 h bar compared to the original membranes. Rejection of dye Blue Dextran (MM = 69 kg / mole) is reduced by 20%. The addition of CNF to the outside coagulant led to the formation of not only the inside selective layer, but also the outer one, while the permeability increases 1.5 times, and the rejection of the dye also increases from 96 to 99%.

Approbation of the Mathematical Model of Adhesive Strength with Viscoelasticity
Authors: Litvinov Stepan V. , Song Xuan Zhen , Yazyev Serdar B. , Avakov Artur
Published: August 2019

Expressed viscoelasticity of polymeric materials which can develop over a long period of time prevents their widespread. Some types of polymers, such as epoxy resins, can be used to connect various structural elements. The destruction in this case can be caused by the growth of tangential stresses in the adhesive joint and their achievement of some critical value τadhezive, at which the adhesive joint is destroyed.
Five cases of paediatric cervical spine distraction injury
Authors: Andronikou S. , Dix-Peek S. , Meerkotter D.
Published: August 2019

Cervical spine distraction injury was considered rare in children, but current literature claims that atlanto-occipital distraction is a major contributor to paediatric trauma mortality. Lower cervical spine distraction is considered rare and usually results in quadriplegia. Three cases of atlanto-occipital distraction are presented here, supporting these claims. The two cases of lower cervical spine distraction are presented as good examples of a rare injury that is sustained in the same manner as atlanto-occipital distraction, but may result in survival of the patient with quadriplegia.
A review of paediatric abdominal masses
Authors: Kader E. , Andronikou S. , Welman C.
Published: August 2019

The extensive differential diagnosis of a paediatric abdominal mass may be considerably narrowed by considering the clinical information and radiographic characteristics. Less than half of abdominal masses are surgical and, of these, nearly all are retroperitoneal, and usually renal. A neonatal abdominal mass is usually benign, retroperitoneal and renal, caused in particular by hydronephrosis and multicystic dysplastic kidney. The commonest neonatal benign and malignant tumours are mesoblastic nephroma and sacrococcygeal teratoma respectively. In the older child abdominal masses are most likely to be malignant retroperitoneal tumours, especially neuroblastoma and Wilm's tumour. The commonest benign mass in this age group is appendix abscess. The initial radiological investigation is a plain abdominal film. In the neonate, where the most likely cause is a benign cystic mass, ultrasound is the preferred subsequent investigation. In the older child, where the risk of malignancy is higher, it may be justifiable to use CT in preference to ultrasound. The spectrum of abdominal masses in paediatric practice is diverse, but a knowledge of the statistical distribution, clinical features and imaging characteristics allows the formulation of a focused differential.

Arteriovenous shunting and early cortical venous filling in subacute cerebral infarction: An old angiographic finding revisited
Authors: Duncan Ian C.
Published: August 2019

Demonstrated in this report is an example of arteriovenous shunting and early venous filling in an area of cerebral infarction recorded on digital subtraction angiography. This angiographic appearance is largely of historical interest given the current use of sectional imaging (CT and MR) and altered role of angiography in the imaging of stroke, but should nevertheless still be considered amongst the differential causes of cerebral arteriovenous shunting.

Evaluation of a multi-model, multi-constituent assimilation
framework for tropospheric chemical reanalysis
Authors: Miyazaki Kazuyuki , Bowman Kevin W. , Yumimoto Keiya , Walker Thomas , Sudo Kengo
Published: August 2019

Abstract. We introduce a Multi-mOdel Multi-cOnstituent Chemical data assimilation (MOMO-Chem) framework that directly accounts for model error in transport and chemistry by integrating a portfolio of forward chemical transport models (GEOS-Chem, AGCM-CHASER, MIROC-Chem, MIROC-Chem-H) into a state-of-the-art ensemble Kalman filter data assimilation system that simultaneously optimizes both concentrations and emissions of multiple species through ingestion of a suite of measurements (ozone, NO2, CO, HNO3) from multiple satellite sensors. In spite of substantial model differences, the observational density and accuracy was sufficient for the assimilation to reduce the multi-model spread by 20–85 % for ozone, and annual mean bias by 39–97 % for ozone in the middle troposphere, while simultaneously reducing the tropospheric NO2 column biases by more than 40 %, and the negative biases of surface CO in the Northern Hemisphere by 41–94 %. For tropospheric mean OH, the multi-model mean meridional hemispheric gradient was reduced from 1.32 ± 0.03 to 1.19 ± 0.03, while the multi-model spread was reduced by 24–58 % over polluted areas. These improvements extended to emissions where uncertainty ranges in the a posteriori emissions due to model errors were quantified in 4–31 % for NOx and 13–35 % for CO regional emissions. Harnessing assimilation increments in both NOx and ozone, we show that the sensitivity of ozone and NO2 surface concentrations to NOx emissions varied by a factor of 2 for end-member models revealing fundamental differences in the representation of fast chemical and dynamical processes. Consequently, diagnostic information readily available from MOMO-Chem has the potential to improve chemical predictions through relationships such as emergent constraints.
Ocean acidification and high irradiance stimulate the photo-physiological fitness, growth and carbon production of the Antarctic cryptophyte Geminigera cryophila
Authors: Trimborn Scarlett , Thoms Silke , Karitter Pascal , Bischof Kai
Published: August 2019

Abstract. Ecophysiological studies on Antarctic cryptophytes to assess whether
climatic changes such as ocean acidification and enhanced stratification
affect their growth in Antarctic coastal waters in the future are lacking so
far. This is the first study that investigates the combined effects of the increasing availability of pCO2 (400 and 1000 µatm) and
irradiance (20, 200 and 500 µmol photons m−2 s−1) on growth,
elemental composition and photophysiology of the Antarctic cryptophyte
Geminigera cryophila. Under ambient pCO2, this species was characterized by a pronounced
sensitivity to increasing irradiance with complete growth inhibition at the
highest light intensity. Interestingly, when grown under high pCO2 this
negative light effect vanished, and it reached the highest rates of growth and
particulate organic carbon production at the highest irradiance compared to
the other tested experimental conditions. Our results for G. cryophila reveal beneficial
effects of ocean acidification in conjunction with enhanced irradiance on
growth and photosynthesis. Hence, cryptophytes such as G. cryophila may be potential
winners of climate change, potentially thriving better in more stratified
and acidic coastal waters and contributing in higher abundance to future
phytoplankton assemblages of coastal Antarctic waters.
River patterns reveal landscape evolution at the edge of subduction, Marlborough Fault System, New Zealand
Authors: Duvall Alison R. , Harbert Sarah A. , Upton Phaedra , Tucker Gregory E. , Flowers Rebecca M. , Collett Camille
Published: August 2019

Abstract. Here we examine the landscape of New Zealand's Marlborough Fault System, where the Australian and Pacific plates obliquely collide, in order to consider landscape evolution and the controls on fluvial patterns at complicated plate tectonic boundaries. Based on topographic patterns, we divide the study area into two geomorphic domains, the Kaikōura and Inland Marlborough regions. We present maps of drainage anomalies and channel steepness, as well as an analysis of the plan view orientations of rivers and faults, and find abundant evidence of structurally-controlled drainage and a history of capture and rearrangement. Channel steepness is highest in a zone centered on the Kaikōura domain, including within the low-elevation valleys of main stem rivers and at tributaries near the coast. This pattern is consistent with an increase in rock uplift rate toward a subduction front that is locked on its southern end. Based on these results and a wealth of previous geologic studies, we propose two broad stages of landscape evolution over the last 25 million years of orogenesis. In the Kaikōura domain, Miocene folding above blind thrust or reverse faults generated prominent mountain peaks and formed major transverse rivers early in the plate collision history. A transition to Pliocene dextral strike-slip faulting and widespread uplift led to cycles of river channel offset, deflection and capture of tributaries draining across active faults, and headward erosion and captures by major transverse rivers within the Inland Marlborough domain. Despite clear evidence of recent rearrangement of the Inland Marlborough drainage network, rivers in this domain still flow parallel to the older faults, rather than along orthogonal traces of younger, active faults. Continued flow in the established drainage pattern may indicate that younger faults are not yet mature enough to generate the damage and weakening needed to reorient rivers. We conclude that faulting, uplift, river capture and drainage network entrenchment all dictate drainage patterns and that each factor should be considered when assessing tectonic strain from landscapes, particularly at long-lived and complex tectonic boundaries.
VISIR-1.b: ocean surface gravity waves and currents for energy-efficient navigation
Authors: Mannarini Gianandrea , Carelli Lorenzo
Published: August 2019

Abstract. The latest development of the ship-routing model published in Mannarini et al. (2016a) is VISIR-1.b, which is presented here. The new version of the model targets large ocean-going vessels by considering both ocean surface gravity waves and currents. To effectively analyse currents in a graph-search method, new equations are derived and validated against an analytical benchmark. A case study in the Atlantic Ocean is presented, focussing on a route from the Chesapeake Bay to the Mediterranean Sea and vice versa. Ocean analysis fields from data-assimilative models (for both ocean state and hydrodynamics) are used. The impact of waves and currents on transatlantic crossings is assessed through mapping of the spatial variability in the tracks, an analysis of their kinematics, and their impact on the Energy Efficiency Operational Indicator (EEOI) of the International Maritime Organization.
Sailing with or against the main ocean current is distinguished. The seasonal dependence of the EEOI savings is evaluated, and greater savings with a higher intra-monthly variability during winter crossings are indicated in the case study. The total monthly mean savings are between 2 % and 12 %, while the contribution of ocean currents is between 1 % and 4 %. Several other ocean routes are also considered, providing a pan-Atlantic scenario assessment of the potential gains in energy efficiency from optimal tracks, linking them to regional meteo-oceanographic features.
The road weather model RoadSurf (v6.60b) driven by the regional climate model HCLIM38: evaluation over Finland
Authors: Toivonen Erika , Hippi Marjo , Korhonen Hannele , Laaksonen Ari , Kangas Markku , Pietikäinen Joni-Pekka
Published: August 2019

Abstract. In this paper, we evaluate the skill of the road weather
model RoadSurf to reproduce present-day road weather conditions in Finland.
RoadSurf was driven by meteorological input data from cycle 38 of the
high-resolution regional climate model (RCM) HARMONIE-Climate (HCLIM38) with
ALARO physics (HCLIM38-ALARO) and ERA-Interim forcing in the lateral
boundaries. Simulated road surface temperatures and road surface conditions
were compared to observations between 2002 and 2014 at 25 road weather
stations located in different parts of Finland. The main characteristics of
road weather conditions were accurately captured by RoadSurf in the study
area. For example, the model simulated road surface temperatures with a mean
monthly bias of −0.3 ∘C and mean absolute error of 0.9 ∘C. The RoadSurf's output bias most probably stemmed from
the absence of road maintenance operations in the model, such as snow
plowing and salting, and the biases in the input meteorological data. The
biases in the input data were most evident in northern parts of Finland,
where the regional climate model HCLIM38-ALARO overestimated precipitation
and had a warm bias in near-surface air temperatures during the winter
season. Moreover, the variability in the biases of air temperature was found
to explain on average 57 % of the variability in the biases of road
surface temperature. On the other hand, the absence of road maintenance
operations in the model might have affected RoadSurf's ability to simulate
road surface conditions: the model tended to overestimate icy and snowy road
surfaces and underestimate the occurrence of water on the road. However, the
overall good performance of RoadSurf implies that this approach can be used
to study the impacts of climate change on road weather conditions in Finland
by forcing RoadSurf with future climate projections from RCMs, such as HCLIM.
Cluster wakes impact on a far distant offshore wind farm's power
Authors: Schneemann Jörge , Rott Andreas , Dörenkämper Martin , Steinfeld Gerald , Kühn Martin
Published: August 2019

Abstract. Our aim with this paper was the analysis of the influence of offshore cluster wakes on the power of a far distant wind farm. We measured cluster wakes with long range Doppler light detection and ranging (lidar) and satellite synthetic aperture radar (SAR) in different atmospheric stabilities and analysed their impact on the 400 MW offshore wind farm "Global Tech I" in the German North Sea using supervisory control and data acquisition (SCADA) power data. Our results showed clear wind speed deficits that can be related to the wakes of wind farm clusters up to 55 km upstream in stable and weakly unstable stratified boundary layers resulting in a clear reduction in power production. We discussed the influence of cluster wakes on the power production of a far distant wind farm, cluster wake characteristics and methods for cluster wake monitoring. In conclusion, we proved the existence of wake shadowing effects with resulting power losses up to 55 km downstream and encouraged further investigations on far reaching wake shadowing effects for optimized areal planning and reduced uncertainties in offshore wind power resource assessment.
After Death, Death: The Mechanics of Longing in Henry Carrington's «The Siren»
Authors: Teodorski Marko
Published: August 2019

This essay deals with the mechanics of longing in a late Victorian siren poem by Henry Carrington, The Siren. Although Victorian literature was teeming with short stories, poems and novels on sirens, this genre, that builds upon and reverses Homeric siren tradition, remains neglected in literary discussions. With the translation of The Little Mermaid into English in 1872, the image of a "longing siren" was born. No longer were these the stories of Odysseus who had survived the siren song: now they were about the sirens’ own sorrows, griefs and desires. Sirens became profoundly human – they became desiring subjects themselves.
Leadership Development of Technology Students Through Experiential Learning
Authors: Moraes Taciano Messias , Guedes Leonardo G. de R. , Root Sheryl
Published: August 2019

Numerous studies show that leadership is one of the factors that impact most on software projects’ success. But even with more than $14B spent yearly on leadership development, it is worrying that more than half of the organizations still believe they are not doing it effectively. One of the most efficient methodologies used in companies is David Kolb’s Experiential Learning, but still uncommon on universities due to the difficulty of simulating practical experiences. Many approaches have been tried with various results and little standardization. For this reason, this study proposes a model for using group activities to help technology students practice leadership skills. A first pilot was executed with positive outcome but more experiments are necessary to ensure its application on other skills and contexts.
INFLUENCE OF FLUOROACRYLATE CURE SITE MONOMER ON THE THERMAL AND MECHANICAL PROPERTIES OF THE POLYACRYLIC ESTER ELASTOMER
Authors: Saha Tuhin , Bhowmick Anil K. , Oda Takeshi , Miyauchi Toshiaki , Fujii Nobuhiko
Published: August 2019

The rubber industry is facing strong challenges in recent times because of imposed stringent standards on the performance of a product under adverse thermal and chemical applications. The choice of proper elastomer plays a significant role in imparting useful product performance. A new type of acrylic rubber with a fluoroacrylate cure site monomer was developed. Structural characterization, such as Fourier-transform infrared spectroscopy and nuclear magnetic resonance (NMR), suggested the presence of four different monomer units. Two-dimensional NMR spectroscopy analysis was also performed to support the assessment of the resonance peaks of coupled nuclei spins in the terpolymer. The newly developed acrylic rubber exhibited superior thermal and mechanical properties. Hexamethylenediamine carbamate in combination with zinc oxide (ZnO) was used as the curing package for the new elastomer. ZnO acts as an acid scavenger to avoid the micro-void formation. The new elastomer with a higher number of cross-link junctions resulted in superior mechanical and thermal properties as well as swelling resistance of the vulcanizate both with and without carbon black.

Schiller Revisited: Aesthetic Play as the Solution to Halbbildung and Instrumental Reason
Authors: Svanøe Lisbet Rosenfeldt
Published: August 2019

Aesthetic experiences reconcile human dualism between sensibility and reason and hence enables us to experience freedom of choice. This article investigates the interconnection of Schiller’s Überdie ästhetische Erziehung des Menschen and Adorno’s Theorie der Halbbildung. Schiller foresaw the instrumental rationalism Adorno described as a consequence of Enlightenment and suggested that aesthetic education as a significant part of Bildung would be the protection against it. I interpret Schiller’s philosophy as dialectical and him as a precursor of both critical theory and a hermeneutic/phenomenological understanding of art. This article analyzes aesthetic playfulness as a creation of emotional and rational experimental spaces that have an important impact on ethical and political formation.
How does it feel to be evaluated? A systemic look at postgraduate students
Authors: Carvalho Deise V. P. , Ranal Marli A. , Mendes-Rodrigues Clesnan
Published: August 2019

The structural constellation, applicable to education, was used to test the hypothesis that postgraduate students do not have difficulties to be evaluated. To test this hypothesis, the WHOQOL-BREF questionnaire (World Health Organization Quality of Life Instrument abbreviated) was applied to 36 students of the Postgraduate Program in Agronomy of the Universidade Federal de Uberlândia, on the first and last days of the school semester of 2017. Half of these students spontaneously accepted to participate in the constellation and responded to two systemic questionnaires, one at the beginning and the other at the end of the semester. During the first month of classes, the 18 students were submitted to the nine squares of the structural constellation technique. At the beginning of the semester, the two groups presented the same quality of life profile. After the constellation, the desire of the 18 students to increase their comfort during the assessments was achieved. In addition, the constellation improved the quality of life of the treated group, regarding the psychological and the environment domains. Another important aspect was the positive correlation between the desire of greater comfort during the assessments and the social domain, before the constellation, and with the psychological domain after the constellation. Knowing that the two groups were initially equal and that the quality of life was improved for the group that participated in the constellation, we hope that this type of therapy can help students to look at the evaluation process with more self-confidence and tranquility, which may improve their academic performance.
Visualizing State Identification in Auto-Regressive Hidden Markov (ARHMM) Models With the Forward and Backward Algorithms Using Excel
Authors: Laverty William. H. , Kelly Ivan. W.
Published: August 2019

Earlier articles, Laverty, Miket, Kelly (2002c), Laverty and Kelly (2019) used Excel to simulate Hidden Markov models and calculate the probabilities of the unknown states using the forward and backward algorithms (Rabiner, 1989). In those articles, independence between observations in each state were assumed. In many situations, however, the assumption of independence within states cannot be made. A more appropriate model for the data in this case would be an Autoregressive Hidden Markov model which accounts for serial correlation within states. In this article, a two-state ARHMM will be simulated with the forward-backward algorithm used to calculate conditional state probabilities given the observed data.

The State of Espírito Santo, Brazil, has micro-regions with different climatic and soil conditions, which promote grapevine cultivation vine in several municipalities. However, the grape production process is strongly threatened by foliar fungal diseases, and its control increases the cost of production significantly. In turn, the use of models of prediction of disease occurrence allows the identification of regions with climatic risk potential for grapevine. Hence, the objective of this work was to analyze the agro-climatic favorability of climatic risk for occurrence of fungal diseases of downy mildew (Plasmopara viticola) and Botrytis cinerea on the grapevine for the municipality of Santa Teresa, in the state of Espírito Santo. Predictive models of favorability of downy mildew and B. cinerea were used. The number of sprayings was determined by the calendar system and by the rainfall system, according to the length of the cycle. Therefore, a series of meteorological data from 2007 to 2016 was used. The results showed that the frequency of days with low risk of mildew was 2%, medium risk 5%, high risk 93%. For B. cinerea, these values were 32%, 68%, and 0%, with low, medium and high risk, respectively. The number of required sprayings, according to the weather conditions, was lower than the number of sprayings recommended by the calendar system. The relationship between the risk of occurrence of the evaluated diseases showed a higher agro-meteorological favorability of occurrence of mildew in relation to B. cinerea.
Maize (Zea mays) Cultivated in Concrectionary Petric Plinthosol
Authors: Nikkel Marcio , Lima Saulo O.
Published: August 2019

Soil with ironstone concretions, despite presenting disadvantages from the agronomic point of view, don’t restrain its use in agriculture, livestock or forestry. However, more deeply and clear information about the behavior of crops of agricultural interest cultivated in this type of soil is absent. Due to the observation of agricultural stands with crops in this type of soil, the hypothesis that plinthite ironstone concretions in the soil interfered negatively in the development, at least in early stages, on crops of agro-economic interest. The objective was to verify the growth and development of maize (Zea mays) cultivated in soil with the presence of plinthite ironstone concretions and in the absence of them. Concretionary Petric Plinthosol were collected in the 0-0.20 m layer and part of the soil was sieved so that concretions larger than 3.10 mm in diameter were removed, thus leaving two treatments, soil with and without plinthite ironstone concretions. The experiment was then carried out and morphological and gas exchange evaluations were performed during their phenological phase. Maize grown in soil without ironstone concretions showed higher growth when compared to maize grown in soil with ironstone concretions, as well variation on gas exchange evaluation and leaf chlorophyll index. There were differences in the root and total dry matter values with more expressive value of the crops cultivated in soil without ironstone concretions. Therefore, it is concluded that plinthite ironstone concretions interfere in the development and growth of maize crop.

Behavior analysis and plant expression are the answers the researcher needs to construct predictive models that minimize the effects of the uncertainties of field production. The objective of this study was to compare the simple and multiple linear regression methods and the artificial neural networks to allow the maximum security in the prediction of harvest in ‘Gigante’ cactus pear. The uniformity test was conducted at the Federal Institute of Bahia, Campus Guanambi, Bahia, Brazil, coordinates 14°13′30″ S, 42°46′53″ W and altitude of 525 m. At 930 days after planting, we evaluated 384 basic units, in which were measured the following variables: plant height (PH); cladode length (CL), width (CW) and thickness (CT); cladode number (CN); total cladode area (TCA); cladode area (CA) and cladode yield (Y). For the comparison between the artificial neural networks (ANN) and regression models (single and multiple-SLR and MLR), we considered the mean prediction error (MPE), the mean quadratic error (MQE), the mean square of deviation (MSD) and the coefficient of determination (R2).The values estimated by the ANN 7-5-1 showed the best proximity to the data obtained in field conditions, followed by ANN 6-2-1, MLR (TCA and CT), SLR (TCA) and SLR (CN). In this way, the ANN models with the topologies 7-2-1 and 6-2-1, MLR with the variables total cladode area and cladode thickness and SLR with the isolated descriptors total cladode area and cladode number, explain 85.1; 81.5; 76.3; 74.09 and 65.87%, respectively, of the yield variation. The ANNs were more efficient at predicting the yield of the ‘Gigante’ cactus pear when compared to the simple and multiple linear regression models.

Maize plays an important role in the national and global economy, continuously increasing its total production due to advances in technology and access to new land areas. Thus, new sources of germplasm are fundamental to generate cultivars more adapted to the diversity of environments and planting times. The objective of this study was to evaluate 36 populations of maize in three environments, aiming to identify the existence of genotype-by-environment interaction, classify populations based on adaptability and stability using the methods of regression and mixed models, indicate the best populations, and compare the two methodologies. The environments evaluated were: E1-second crop (safrinha) season of 2016 in an experimental area of latosol, with incidence of water stress; E2-crop season 2016/2017 in sandy soil, in family farm area; and E3-crop season 2016/2017 in an experimental area of latosol, no incidence of water stress. Grain yield was evaluated, adaptability and stability analysis was performed. Population 36 achieved high productivity, adaptability and general stability in three tested environments. Both methodologies showed similar results regarding adaptability and stability of some populations in three environments, but mixed models were more suitable for providing better selective accuracy.

The biggest challenge facing in sugar-energy plants is to move towards the biorefinery concept, without threatening the environment and health. Energy cane is the state-of-the-art of smart energy crops to provide suitable whole-raw material to produce upgraded biofuels, dehydrated alcohol for transportation, refined sugar, yeast-fermented alcoholic beverages, soft drinks, silage and high-quality fodder, as well as to cogenerate heat and bioelectricity from burnt lignocellulose. We, accordingly, present fuzzy c-means (FCM) clustering algorithm interconnected with principal component analysis (PCA) as powerful exploratory data analysis tool to wisely classify hybrids of energy cane for production of first-generation ethanol and cogeneration of heat and bioelectricity. From the orthogonally-rotated factorial map, fuzzy cluster I aggregated the hybrids VX12-0277, VX12-1191, VX12-1356 and VX12-1658 composed of higher contents of soluble solids and sucrose, and larger productive yields of fermentable sugars. These parameters correlated with the X-axis component referring to technological quality of cane juice. Fuzzy cluster III aggregated the hybrids VX12-0180 and VX12-1022 consisted of higher fiber content. This parameter correlated with the Y-axis component referring to physicochemical quality of lignocellulose. From the PCA-FCM methodology, the conclusion is, therefore, hybrids from fuzzy cluster I prove to be type I energy cane (higher sucrose to fiber ratio) and could serve as energy supply pathways to produce bioethanol, while the hybrids from fuzzy cluster III are type II energy cane (lower sucrose to fiber ratio), denoting potential as higher fiber yield biomass sources to feed cogeneration of heat and bioelectricity in high temperature and pressure furnace-boiler system.

The objective of this work was to evaluate the silvicultural implications in a Eucalyptus urophylla S.T. Blake × Eucalyptus grandis Hill ex Maiden (Eucalyptus urograndis) stand 4.5 years-old, located in Alegrete - RS. The trees were fractionated in the following components: root, wood, bark, branches and leaves for later estimation of nutrient content and stock. An inventory was made for the dendrometric characterization of the stand. The nutrient concentration and stock in each component were evaluated. The nutrient removal was estimated considering three biomass harvesting scenarios: wood with bark + canopy, wood with bark and wood only. The nutritional balance and the number of rotations (4.5 years) of production were determined, considering the nutrient stock in the soil, the inputs through precipitation + mineral fertilization and the outputs from the biomass harvest. The risk of yield limitation among the nutrients considering the harvest of biomass showed the following pattern: Wood with bark + canopy: Sulfur ~ Potassium > Nitrogen > Calcium > Magnesium; Wood with bark: Sulfur > Potassium > Calcium > Nitrogen > Magnesium; Wood: Sulfur > Potassium > Nitrogen > Magnesium > Calcium. Phosphorus showed a tendency of nutritional sustainability in the three harvest scenarios evaluated.
WILANÓW WORKS OF ART IN THE GERMAN
CATALOGUE SICHERGESTELLTE KUNSTWERKE
IM GENERALGOUVERNEMENT
Authors: Kudelski Jarosław Robert
Published: August 2019

Before the outbreak of WW II, the works of world
art collected at the Wilanów Palace were considered to be
the largest private collection in the Polish territories. Just the
very collection of painting featured 1.200 exhibits. Apart from
them the Wilanów collection contained historic furniture, old
coins, textiles, artistic craftsmanship items, drawings, and
prints, pottery, glassware, silverware, bronzes, sculptures,
as well as mementoes of Polish rulers. Already in the first
weeks of the German occupation, assigned officials selected
the most precious art works from the Wilanów collections,
and included them in the Sichergestellte Kunstwerke im
Generalgouvernement Catalogue. The publication presented
the most precious cultural goods secured by the Germans
in the territory of occupied Poland. It included 76 items: 29 paintings and 47 artistic craftsmanship objects. In 1943,
the majority of the works included in the quoted Catalogue
were transferred to Cracow. A year later, the most valuable
exhibits from Wilanów were evacuated to Lower Silesia. What
remained in Cracow was only a part of the collection relocated
from Wilanów. The chaos of the last weeks preceding the
fall of the Third Reich caused that many art works from the
Wilanów collection are considered war losses. Among many
objects, included in the above Catalogue, there are several
Wilanów paintings: Portrait of a Man by Bartholomeus van
der Helst, Portrait of a Married Couple by Pieter Nason,
Allegory of Architecture, Painting, and Sculpture by Pompeo
Batoni, Allegorical Scene in Landscape by Paris Bordone, and
The Assumption of Mary by Charles Le Brun.

Este artigo apresenta algumas características organizativas e operacionais da Atenção Primária à Saúde (APS) inglesa. Seu objetivo é evidenciar pontos relevantes no funcionamento das clínicas da APS que facilitam o equilíbrio dinâmico entre o atendimento à demanda espontânea e as ações programáticas em saúde. Ele tem como base um estudo etnográfico, realizado no Reino Unido no período de 2013/14, no qual se analisou o modelo de pagamento por desempenho no país. Os tópicos abordados incluem: (a) composição das equipes da APS inglesa; (b) organograma funcional de uma clínica de APS; (c) consulta de 10 minutos dos médicos de família e horário de funcionamento da clínica; (d) recepção; (e) equipe de enfermagem; e (f) sistema de tecnologia da informação. Cada um desses itens possui referências para as quais é possível explorar websites e tutoriais de modo a compreender melhor alguns aspectos das clínicas da APS inglesa. O Reino Unido profissionalizou o acesso dos pacientes aos serviços da APS. Isto ocorreu por meio de um contingente maior de pessoal administrativo, menor proporção população/médico de família, maior autonomia da equipe de enfermagem e um robusto sistema de tecnologia da informação. No Brasil, a Estratégia Saúde da Família (ESF) necessita percorrer caminho semelhante a fim de aprimorar a qualidade da APS no país.
