Dispersal and migration of a specialist waterbird: where do Eurasian Spoonbills (Platalea leucorodia) come to Hungary from?
Authors: Pigniczki Csaba
Published: August 2017

Between 1950 and 2016, 254 individuals of Eurasian Spoonbill (Platalea leucorodia) of foreign origin were observed during their dispersal or migration in Hungary from eight countries. Colour-ringed birds originating from Serbia, Croatia and the Czech Republic were the most commonly observed, while individuals from Italy, the Danube Delta (Romania) and the Wadden Sea area (Denmark and The Netherlands) were observed rarely in Hungary. Only metal ringed Spoonbills were recovered from Austria. All age-classes were found in Hungary: juveniles were the most common, while 2cy immatures formed the rarest class. Adults from the Wadden Sea area, and also from the Danube Delta were observed in Hungary during the breeding season, implying potential gene flow between those areas and the Carpathian Basin. My results predict that the breeding population of the Carpathian Basin forms a unique subunit of a metapopulation which is in close contact with the Czech population. The nesting of adults of Serbian and Croatian origin was confirmed in Hungary. Two prospecting subadults (4cy) were observed in Hungarian colonies, one was from Serbia, and the other was from Italy. One adult (5cy) occurred in several Hungarian wetlands in a short period before breeding, which probably explored habitats for breeding or for feeding. Spoonbills of Czech, Serbian, Croatian and Italian origin observed in Hungary used the Central Mediterranean or the Adriatic Flyway. Individuals from the East Atlantic population arrived to Hungary by shifting their migration routes. One bird from the Danube Delta wintered in Tunisia, where it probably joined Hungarian breeders and reached Hungary with them. Adults and juveniles from the Czech Republic used the wetlands around Lake Neusiedler as a stop-over and staging area during autumn migration. My results suggest that Hungarian wetlands play an important role in the movements and breeding of Spoonbills in Central Europe, thus, the management and conservation of these wetlands are essential for the future.

Published: August 2017

Due to conservation measures, the breeding population of the Raven significantly strengthened over the last decades in Hungary, also nesting on the lowlands. Nowadays, observing large flocks is not rare. Compared to other European countries, the urbanization of the species began relatively late in Hungary, in the ‘90s, first breeding in the urban areas of Baranya County. There were another five similar known cases after the millennium across the country. Because of the advanced adaptive capacity of species, this number is likely to grow in the future. In Hungary, the brood is typically complete in the second half of February and the young birds fledge in the first days of May. There are two known cases after the millennium when the Ravens bred in a significantly different time than usual. In these cases, the young birds fledged on 20 January and the second half of February. In both cases, the nests were found on overhead transmission line poles in lowland agricultural areas. It is uncertain what led to the unusual breeding time, but it is most likely that the breeding pair was accustomed, having successfully raised several brood before, and they could rely on the abundant food base near the nests during the breeding period.

Published: August 2017

Ornithological studies often rely on long-term bird ringing data sets as sources of information. However, basic descriptive statistics of raw data are rarely provided. In order to fill this gap, here we present the third item of a series of exploratory analyses of migration timing and body size measurements of the most frequent Passerine species at a ringing station located in Central Hungary (1984-2016). First, we give a concise description of foreign ring recoveries of the Song Thrush in relation to Hungary. We then shift focus to data of 4137 ringed individuals and 1051 recaptures derived from the ringing station, where birds have been trapped, handled and ringed with standardized methodology since 1984. Timing is described through annual and daily capture and recapture frequencies and their descriptive statistics. We show annual mean arrival dates within the study period and present the cumulative distributions of first captures with stopover durations. We present the distributions of wing, third primary, tail length and body mass, and the annual means of these variables. Furthermore, we show the distributions of individual fat and muscle scores, and the distributions of body mass within each fat score category. We distinguish the spring and autumn migratory periods, breeding and wintering seasons, and age groups (i.e. juveniles and adults). Our aim is to provide a comprehensive overview of the analysed variables. However, we do not aim to interpret the obtained results, merely to draw attention to interesting patterns that may be worth exploring in detail. Data used here are available upon request for further analyses.

This paper presents ambiguity resolution in the range-based ZigBee positioning system. The system is using the phase shift measurements to determine the distances between user and anchors. In this paper, the ambiguity is defined as the number of full reps of a certain distance added to the measurement result. The way of resolving ambiguities in the positioning system is described and an experiment results are presented. Featured algorithm is successful in finding ambiguities and correct location of the user.
Verification and Updating of the Database of Topographic Objects with Geometric Information About Buildings by Means of Airborne Laser Scanning Data
Authors: Mendela-Anzlik Małgorzata , Borkowski Andrzej
Published: August 2017

Airborne laser scanning data (ALS) are used mainly for creation of precise digital elevation models. However, it appears that the informative potential stored in ALS data can be also used for updating spatial databases, including the Database of Topographic Objects (BDOT10k). Typically, geometric representations of buildings in the BDOT10k are equal to their entities in the Land and Property Register (EGiB). In this study ALS is considered as supporting data source. The thresholding method of original ALS data with the use of the alpha shape algorithm, proposed in this paper, allows for extraction of points that represent horizontal cross section of building walls, leading to creation of vector, geometric models of buildings that can be then used for updating the BDOT10k. This method gives also the possibility of an easy verification of up-to-dateness of both the BDOT10k and the district EGiB databases within geometric information about buildings. For verification of the proposed methodology there have been used the classified ALS data acquired with a density of 4 points/m2. The accuracy assessment of the identified building outlines has been carried out by their comparison to the corresponding EGiB objects. The RMSE values for 78 buildings are from a few to tens of centimeters and the average value is about 0,5 m. At the same time for several objects there have been revealed huge geometric discrepancies. Further analyses have shown that these discrepancies could be resulted from incorrect representations of buildings in the EGiB database.
Integrated Precipitable Water from GPS Observations and CIMEL Sunphotometer Measurements at CGO Belsk
Authors: Kruczyk Michał , Liwosz Tomasz , Pietruczuk Aleksander
Published: August 2017

This paper describes results of integrated precipitable water co-located measurements from two techniques: GPS solution and CIMEL-318 sunphotometer. Integrated Precipitable Water (IPW) is an important meteorological parameter and is derived from GPS tropospheric solutions for GPS station at Central Geophysical Observatory (CGO), Polish Academy of Sciences (PAS), Belsk and compared with sunphotometer (CIMEL-318 device by Cimel Electronique) data provided by Aerosol Robotic Network (AERONET). Two dedicated and independent GPS solutions: network solution in the sub-network of European Permanent Network (EPN) and precise point positioning solution have been made to obtain tropospheric delays. The quality of dedicated tropospheric solutions has been verified by comparison with EPN tropospheric combined product. Several IPW comparisons and analyses revealed systematic difference between techniques (difference RMS is over 1 mm). IPW bias changes with season: annual close to 1 mm IPW (and semi-annual term also present). IPW bias is a function of atmospheric temperature. Probable cause of this systematic deficiency in solar photometry as IPW retrieval technique is a change of optical filter characteristics in CIMEL.
Current insights in CSF leaks: a literature review of mechanisms, pathophysiology and treatment options
Authors: Patrascu Elena , Manea Claudiu , Sarafoleanu Codrut
Published: August 2017

A cerebrospinal fluid (CSF) leak occurs when there appears a fistula between the dura and the skull base and it is usually characterized by discharge of cerebrospinal fluid from the nose. Cerebrospinal fluid leaks may have many etiologies, the most common being trauma. The most common site of dural lesion is the cribriform plate of the ethmoid. Diagnosis can be achieved by a multitude of techniques, high-resolution computed tomography being the modality of choice and it may be completed with magnetic resonance imaging or cisternography. Treatment may be either conservative, either surgical, related to the cause, the site and the duration of CSF leak. Conservative treatment usually includes strict bed rest, elevated bed head and no straining, nose blowing or stretching, with resolution of the majority of traumatic CSF leaks in seven days. Surgical treatment consists of a variety of approaches (intracranial/extracranial, open/endoscopic). The future trend is represented by minimally invasive endoscopic approaches, with a success rate of almost 90%; however, open transcranial or extracranial interventions still have indications in the surgical management. CSF leaks must be correctly diagnosed and treated, because the risk of intracranial complications increases 10-fold when the leakage persists.

Nasolacrimal duct obstruction (NLDO) is a common event in clinical practice. The authors, all members of the Italian Society of Rhinology, analysed 100 cases from different ENT Departments. The causes of NLDO, according to the etiology, can be divided into two classes: idiopathic primary acquired nasolacrimal duct obstruction and secondary. The aim of the study was to describe an association between the sign and symptoms of chronic rhinosinusitis and a complaint of epiphora.
Complex disposition of an enigmatic pathogen: rare electron microscopic manifestations in nasal rhinosporidiosis
Authors: Dhaulakhandi Dhara B. , Ravi Alok K. , Garg Lalit C. , Ahluwalia Karvita B.
Published: August 2017

Rhinosporidiosis is a polypoidal disease of the nose and mucocutaneous tissues, the diagnosis of which is based on the presence of round bodies believed to be causative agents of the disease. Historically, the round body has been considered to be a sporangium of a fungus Rhinosporidium seeberi but without any convincing evidence. Round bodies contain numerous daughter cells, which are likely in the infective stage and are shed through a rupture in the wall of the round body. The released single-celled organisms eventually develop into round bodies on availability of suitable transformative trigger and favourable environment. Surgical excision of the polyp by electrocautery is the only effective treatment; however, recurrence may occur due to spillage of infective endospores in the surrounding mucosa during removal. There are many enigmatic features of the causative agent of this disease, which have been baffling researchers for more than a century. Here we present some rare electron microscopic and previously unreported features of the coat of the round body and single-celled organism in nasal rhinosporidiosis.

Published: August 2017

Psoriasis vulgaris is a chronic inflammatory dermatosis with major impact on patients’ life quality. The etiopathogenesis is multifactorial, depending on complex interactions between genetic and environmental factors. We present the case of two female patients, identical twins of 33 years old, suffering from psoriasis vulgaris since childhood. Patient A developed specific lesions of psoriasis at the age of 7 and patient B started to develop psoriasis lesions on the scalp two years later. At the age of 31, patient A was diagnosed with psoriatic arthritis. Laboratory test results were within the normal ranges for both patients. Hormonal and immunological determinations revealed the presence of a high level of antithyroidperoxidase antibody in patient A and increased level of prolactin in patient B. Ultrasonographic assessment of the thyroid detected the presence of bilateral micronodules in the first subject. Knowing that early onset psoriasis is associated with the presence of Human Leukocyte Antigen Cw6(HLA-Cw6), we aimed to confirm this hypothesis for our subjects. Although HLA-Cw6 is the most frequent mutation in psoriasis patients and it is present in about two-thirds of the tested subjects,the genetic results for both patients were negative, strengthening the fact that other factors, the environmental one and the hormonal disorders had an important role in their psoriasis pathogenesis. Under these conditions, we emphasize the importance of including a hormonal evaluation approach of psoriasis patients in order to diagnose and treat pathologies that may be related with disease exacerbations

Published: August 2017

Hybridization between divergent lineages of common ash Fraxinus excelsior L. was studied in Slovakia and adjacent regions of Hungary, the Czech Republic and Poland in the contact zone between two postglacial colonization routes originating from different glacial refugia. Thirty-eight common ash populations were studied using a combination of 6 maternally inherited chloroplast microsatellite markers and 7 biparentally inherited nuclear microsatellites (nSSR). Two predominant chloroplast lineages were identified, between which the boundary was very sharp. Populations containing a mixture of different haplotypes were found only in the immediate proximity of the boundary. Bayesian analysis of population structure based on nSSR loci revealed the existence of two clusters, which largely coincided with chloroplast lineages. Both haplotype frequencies and proportions of clusters identified by the Bayesian analysis exhibited a clinal transition over the hybrid zone, with cline widths of 36 km for chloroplast haplotype frequencies (reflecting gene flow by seeds) and 275 km for Bayesian clusters based on nSSR (reflecting gene flow by pollen and seeds). Chloroplast haplotype diversity increased along the boundary between lineages not only because of admixture, but also due to the presence of rare haplotypes. In contrast, diversity at nuclear loci did not exhibit any geographical trend.

Published: August 2017

Eucalyptus argophloia Blakely (Western white gum) has shown potential as a commercial forestry timber species in marginal environments of north-eastern Australia. We measured early pollination success in Eucalyptus argophloia to compare pollination methods, determine the timing of stigma receptivity and compare fresh and stored pollen. Early pollination success was measured by counting pollen tubes in the style of E. argophloia 12 days after pollination. We compared the early pollination success of 1) Artificially Induced Protogyny (AIP), one-stop and three-stop methods of pollination; 2) flowers pollinated at 2 day intervals between 2 days before and 6 days after anthesis and 3) fresh pollen and pollen that had been stored for 9 months. Our results show significantly more pollen tubes from unpollinated AIP and AIP treatments than either the one-stop pollination or three-stop pollination treatments. This indicates that self-pollination occurs in the unpollinated AIP treatment. There was very little pollen tube growth in the one-stop method indicating that the three-stop method is the most suitable for this species. Stigma receptivity in E. argophloia commenced six days after anthesis and no pollen tube growth was observed prior to this. Fresh pollen resulted in pollen tube growth in the style whereas the stored pollen resulted in a total absence of pollen tube growth. We recommend that breeding programs incorporating E. argophloia as a female parent use the three-stop pollination method, and controlled pollination be carried out at least six days after anthesis using fresh pollen.
Microarray Analysis of Gene Expression in Triploid Black Poplar

Published: August 2017

Triploidy is a widespread phenomenon in cultivated and natural breeding plants and it can confer some growth advantages. Here, we analyzed genome-wide gene expression in triploid Populus euramericana (black poplar) using the Affymetrix poplar microarray to detect any possible correlation between triploid vigor and a unique gene expression profile. Among the 38,400 transcripts that were detected in triploid poplar, 1,564 and 2,015 genes were up- or downregulated, respectively, compared with the diploid. The majority of the upregulated genes in the triploid were associated with carbon and nitrogen metabolism, especially lignin and secondary metabolism. Other genes upregulated in the triploid included genes involved in sugar transport, and brassinosteroid (BR) and auxin metabolism. Downregulated genes were mostly related to the assembly and biosynthesis of ribosomes and the nucleosome macromolecular complex. The results suggested that BR and auxin levels were crucial in controlling sugar transport, photosynthesis and cell wall biosynthesis. Downregulated genes were associated with chromatin regulation in the triploid. The information from this analysis could provide an insight into the vigor of triploid poplar.
Genetic Control of Growth Traits and Inheritance of Resistance to Bacterial Leaf Scorch in American Sycamore
Authors: Adams J. P. , Rousseau R. J. , Leininger T. D.
Published: August 2017

Open-pollinated progeny tests of American sycamore (Platanus occidentalis L.), which included 55 open-pollinated families selected from several prior Westva - co progeny tests and seed orchards and six control-pollinated families were established in 2002 and 2003. The half-sibling families were planted at two sites in western Kentucky and southeastern Missouri. The six full-sibling families, generated from selections based on exhibition of parental disease resistance and susceptibility to a variety of diseases, were also planted near Stoneville, MS at the US Forest Service Center for Bottomland Hardwoods Research. All full-sibling families planted at the Stoneville site were inoculated in the fall 2002 with the leaf-scorch-causing bacterium, Xylella fastidiosa. Diameter and height data for trees of both half- and full-sibling families were recorded at ages three, five, seven, and nine at the various sites. Bacterial leaf scorch disease presence was also recorded as symptomatic or asymptomatic/ mildly symptomatic. Average family heritability across ages was 0.58, 0.50, and 0.55 for height, diameter, and volume, respectively, indicating that increased growth traits can be gained from family selection. In conjunction with derived age-age correlations, selection based on age-five data results in the greatest gain per unit time for age nine gains for half-sibling families. Breeding for bacterial leaf scorch resistance can also be successfully undertaken if proper selection and breeding of two resistant parents are undertaken which can result in a 4.5 fold decrease in the probability in symptoms of offspring by age nine. Results indicate a large potential for increased growth and disease resistance in American sycamore through traditional breeding.
Statistical associations between morphology, physiology and AFLP DNA markers enable selection of a putative eucalypt hybrid able to tolerate salt affected floodplains
Authors: Koerber G. R. , Hancock T.
Published: August 2017

A naturally occurring putative hybrid between Eucalyptus largiflorens F. Muell and Eucalyptus gracilis F. Muell called Green Box tolerates saline conditions of the River Murray floodplains better than E. largiflorens. Revegetation strategies utilizing seedlings of Green Box have had limited success because only a few are Green Box and the majority are throw backs to E. gracilis and E. largiflorens. Therefore, the purpose of this study was to identify traits characteristic of Green Box and AFLP markers associated with the traits enabling selection at the seedling stage. This was done by non-linear canonical correlation analysis (OVERALS) to test for statistically significant associations between morphological and physiological traits with 232 AFLP markers from 9 primer combinations. OVERALS with all markers produced 1stand 2nddimensions accounting for 80 and 74% of variation respectively. Green Box plants were placed intermediate between E. gracillis and E. largiflorens according to leaf colour, gloss and nitrogen with component loadings (lc) of 0.340, 0.615 and 0.294 respectively. A second approach of simple linear regression of morphological and physiological traits against all 232 AFLP markers singled out 17 with significance P<0.05. Thirteen of these were also identified by OVERALS. Four occurred with high frequency in Green Box and E. largiflorens distinguishing them from E. gracilis. In order to separate Green Box and E. largiflorens, the segregation of a further three markers can be used to align Green Box with E. gracilis. Therefore, the segregation of 7 markers can be utilized to select Green Box.

Published: August 2017

The maintenance, protection, and conservation of forest genetic resources for economic, ecological and social benefits are daunting tasks. Understanding how reforestation materials are spatially and temporally deployed across the landscape is an integral component of forest genetic resources management. To improve the current understanding of how reforestation materials are deployed in British Columbia (BC), we developed a geographical information systems (GIS) method to track seed deployment across silviculture openings. Generally, reforestation materials can originate from either natural stand (wild seed collections) or orchards’ seed sources (improved seed); the latter are produced within the framework of specific tree improvement program designed for a particular species within a well-defined seed deployment area, commonly known as Seed Planning Zone (SPZ). In this paper, we present a GIS-based method for evaluating seed deployment patterns for interior spruce (Picea glauca and Picea engelmannii and their natural hybrids) within the Prince George SPZ. The evaluation period (1970-2004) is associated with wild stands and improved seed availability and the dynamic of each seed source proportionate contribution followed three distinct phases; namely, developing (1970-1987), immature (1988-1994), and mature (1995-2004) with a progressive increase of orchards’ seed use over time. The developed method is scalable across SPZs of the same species or multiple species, thus providing the means to: 1) temporally and spatially monitor improved and natural stands seed deployment over the landscape; and 2) identify areas of concerns where a particular seed source is over-represented which might pose an increased genetic vulnerability. The present study revealed that the current interior spruce orchard’s seed use within the Prince George SPZ is expected to exceed the provincial goal of performance target of 75% by 2014. Additionally, areas of excessive use of one seed orchard seed were identified.

Authors: Ciężkowski Paweł , Maciejewski Jan , Bąk Sebastian
Published: August 2017

This paper presents experimental comparison of two machine crushing technologies: one-stage and two-stage. The study was carried on a model double-toggle jaw crusher which allows crushing forces, energy and toggle displacement to be measured. The main aim of the work was to determine the energy consumption of crushing process assuming a given level of fragmentation. Studies were performed on three rocks: granite “Strzegom”, limestone “Morawica” and sandstone “Mucharz”. The material tested had a cubic shape and average dimension of 90 mm. One-stage crushing was carried out for outlet slot er = 11 mm, and two-stage crushing for er = 24 mm and 11 mm. In the tests special design of variable profile moving jaw was used and fixed jaw was flat. The analysis of the results shows that taking into account energy consumption, it is better to use two-stage crushing process. For given materials energy consumption in the two-stage crushing process was reduced by 30%.

Published: August 2017

Chimeric antigen receptor (CAR) T cell therapy, together with checkpoint inhibition, has been celebrated as a breakthrough technology due to the substantial benefit observed in clinical trials with patients suffering from relapsed or refractory B‐cell malignancies. In this review, we provide a comprehensive overview of the clinical trials performed so far worldwide and analyze parameters such as targeted antigen and indication, CAR molecular design, CAR T cell manufacturing, anti‐tumor activities, and related toxicities. More than 200 CAR T cell clinical trials have been initiated so far, most of which aim to treat lymphoma or leukemia patients using CD19‐specific CARs. An increasing number of studies address solid tumors as well. Notably, not all clinical trials conducted so far have shown promising results. Indeed, in a few patients CAR T cell therapy resulted in severe adverse events with fatal outcome. Of note, less than 10% of the ongoing CAR T cell clinical trials are performed in Europe. Taking lead from our analysis, we discuss the problems and general hurdles preventing efficient clinical development of CAR T cells as well as opportunities, with a special focus on the European stage.
Is myometrial inflammation a cause or a consequence of term human labour?

Published: August 2017

Myometrial inflammation is thought to have a pivotal role in the onset of term and some forms of preterm labour. This is based on the comparison of samples taken from women undergoing term elective CS prior to the onset of labour with those taken from women in established labour. Consequently, it is not clear whether myometrial inflammation is a cause or a consequence of labour. Our objective is to test the hypothesis that myometrial inflammation is a consequence of the onset of labour. To test this hypothesis, we have obtained myometrial samples from women at various stages of pregnancy and spontaneous labour and studied the activation of the AP-1 (c-Jun) and NFκB (p65) systems, cytokine mRNA expression and protein levels and inflammatory cell infiltration and activation. We found that the activation of p65 declined from preterm to term not in labour samples and thereafter increased in early and established labour. Cytokine mRNA expression and protein levels increased in established labour only. Using flow cytometry of myometrial tissue, we found that the number of neutrophils did increase with the onset of labour, but on tissue section, these were seen to be intravascular and not infiltrating into the myometrium. These data suggest that myometrial inflammation is a consequence rather than a cause of term labour.

Authors: Rusmita Sylva Alif , Ajija Shochrul Rohmatul
Published: August 2017

This study aims to analyze the attitudes of consumers towards Islamic and conventional credit cards. Using online questionnaire survey data from 51 respondents in Surabaya, East Java, the study revealed that most consumers possessed credit cards because of their convenience factor, relationship with their existing bank, and card salesmen. Therefore, the sale is the most powerful way to invite the community to have an Islamic credit card. Many customers do not care whether their credit cards are Islamic based or not, as long as the salesman promoted cards to them and the cards are able to meet their personal needs, especially for sales and purchase transactions online, they will utilize the cards. The large number of Muslims in Surabaya should be a share of the lucrative market for Islamic credit cards. Therefore, the education about the Islamic manner of consumption and the dangers of usury should be promoted in Surabaya.DOI: 10.15408/etk.v16i2.5519
Double-transmitting and Sextuple-receiving Borehole Transient Electromagnetic Method and Experimental Study
Authors: Wang Bo , Liu Shengdong , Li Shining , Zhou Fubao
Published: August 2017

With the continuous improvement of precision requirements for borehole geophysical exploration, the application of transient electromagnetic method (from now on referred to as TEM) in a borehole has become a hot spot. The conventional borehole TEM can only determine the longitudinal depth of the geological anomaly, the radial azimuth and depth cannot be resolved. A double-transmitting and sextuple-receiving borehole TEM is proposed, through which the radial anomaly is excited by the electromagnetic field generated by the double-emitting loops, and the azimuth and depth of the anomaly will be identified by the difference characteristics of the six receiving loops signals. In this paper, the response equations of the transmitting-receiving mode of double-transmitting and sextuple-receiving borehole TEM are deduced, and the response characteristics of the induction segment and the attenuation segment of the receiving loops are obtained based on the response equations under ramp function turn-off condition, providing the basis for theoretical analysis. Due to the negative value of the double-transmitting and sextuple-receiving transient electromagnetic response signals, a negative transformation algorithm under the double logarithmic coordinate system is proposed to provide the essential method for the analysis of two kinds of physical simulation experimental data of the radial azimuth and radial depth detection of the anomaly. The results show that the double-transmitting and sextuple-receiving borehole TEM has decent resolution ability in detecting the radial azimuth of the anomaly, and the effective resolution is 30°. The geometric difference among induced voltages of different measuring points can be used to evaluate the radial depth of the anomaly qualitatively. It is expected that the double-transmitting and sextuple-receiving borehole TEM can provide technical guidance for little borehole geophysical exploration in the fields of oil, natural gas, coal and basic engineering construction.
Spatial Quality Control Method for Surface Temperature Observations Based on Multiple Elements
Authors: Ye Xiaoling , Yang Xing , Xiong Xiong , Yang Shuai , Chen Yang
Published: August 2017

Quality control can effectively improve the quality of surface meteorological observations. To ensure the stability and effectiveness of a quality control model under different terrain and climate conditions, it is necessary to structure a quality control model with strong generalization ability. Algorithms such as the Random Forest provide such generalization ability. However, machine learning algorithms are slower than traditional mathematical models. Therefore, a Random Forest quality control algorithm based on the Principal Component Analysis (PCA-RF) is proposed in this paper. Fifteen target stations under different climatic and geomorphological conditions were selected and tested using observations collected four times daily at neighboring stations from 2005-2014. The results show that using PCA to analyze the elemental composition and select elements with high correlation factors, as well as applying the Random Forest algorithm, can effectively reduce the run time and keep the accuracy of the model. The training sample dependence, model prediction accuracy and error detection rate of the PCA-RF model are superior to those of the Spatial Regression method. Therefore, the PCA-RF method is a better-quality control model for the spatial quality control of multiple elements of surface air temperature observations.
Metallogenic Dynamics Background of Ga’erqiong Cu-Au Deposit in Tibet, China

Published: August 2017

The Ga’erqiong Cu-Au deposit, which sits on the north side of the Coqên-Xainzamagmatite belt, is a large-scale skarn-type deposit, whose ore body has formed in the skarn zone in the contact part of quartz diorite and marble of Duoai formation or the cracks of quartz diorite. Its mineralization is closely related to quartz diorite. And granite porphyry-related molybdenum ore still exists in its deep part. Currently, there are disputes about the metallogenic dynamics background of this deposit. From previous studies, this paper carried out zircon LA-LCPMS U-Pb dating and petrogeochemistry study for quartz diorite of Ga’erqiong Cu-Au deposit. The testing result indicates: quartz diorite and granite porphyry were formed respectively in 88±2Ma and 83±1Ma, belonging to the magmatic activity of the early stage of Upper Cretaceous; quartz diorite and granite porphyry have geochemical characteristics similar to those of island arc rock of subduction zone and geochemical indexes similar to “adakite.” Combining with the regional tectonic evolution, we think that quartz diorite and granite porphyry were all formed in the extension environment after the collision of Lhasa block and Qiangtang block. Quartz diorite is the result of the migmatization of basic melt and acid melt evoked by asthenosphere material raise caused by lower crustal delamination; the formation of granite porphyry may be crust-mantle material’s partial melting results due to delaminated lower crustal. Therefore, Ga’erqiongskarn-type Cu-Au deposit belongs to the metallogenic response to the collisional orogeny in the closing process of Meso-Tethys.

Objetivo Durante cirugía, los instrumentadores quirúrgicos adoptan posturas de trabajo que pueden resultar perjudiciales para su sistema músculo-esquelético. La literatura ha identificado que el daño al sistema músculo-esquelético de los instrumentadores depende de si las posturas son estáticas o dinámicas, la especialidad quirúrgica en donde se adoptan, el tipo de cirugía, la ubicación de las mesas de instrumental y la altura de la mesa operatoria. Sin embargo, este estudio identificó las posturas adoptadas por los instrumentadores de una institución de IV nivel de Bogotá durante cirugía, teniendo en cuenta algunas de sus características personales, laborales y también algunas condiciones técnicas de los procedimientos asistidos por los mismos, para determinar los efectos de estas posturas sobre su sistema músculo-esquelético y sugerir modificaciones de ser necesario.Métodos En este estudio descriptivo, la unidad de observación fueron los instrumentadores y la unidad de análisis fueron las posturas adoptadas por los mismos. Se utilizó el método de evaluación postural Ovako Working Posture Analysing System (OWAS) para identificar dichas posturas y categorizarlas según sus efectos sobre el sistema músculo-esquelético.Resultados Se observaron 491 posturas, de las cuales, el 42,6 % fueron de categoría de acción 2 del método OWAS.Conclusiones La adopción de posturas de categoría de acción 2 se relacionó principalmente con la especialidad quirúrgica, el uso de la mesa de instrumental de Mayo, la región anatómica operada en el paciente, el tipo de cirugía, el turno de trabajo, el número de cirugías instrumentadas dentro del turno de trabajo y la ayudantía quirúrgica.

Objetivo Realizar una predicción de la dinámica de la epidemia de malaria para el 2007 en Colombia con base en el análisis de la dinámica geométrica de 1960-2006 como una caminata al azar probabilista.Materiales y Métodos Basados en la caminata al azar probabilística se estudió la dinámica geométrica del número de casos anuales de malaria registrados en Colombia durante los años 1960-2006, analizando el comportamiento probabilístico de aumentos y disminuciones consecutivos, y el comportamiento probabilístico de casos durante rangos de años consecutivos, para así realizar una predicción temporal de los casos.Resultados Se desarrolló una metodología sencilla y acausal  que predice los valores extremos 81 003 y 104 098 para el número de infectados en el año 2007, predicción que fue refinada con el análisis de las variaciones anuales obteniendo un valor de 104 098 para el número de infectados en el año 2007. Esta predicción fue posteriormente corroborada con los datos del Instituto Nacional de Salud de Colombia, correspondiendo al 95,6 % respecto al número de casos reportados.Conclusión La comprensión del fenómeno acausal a partir de la caminata al azar probabilística permite realizar predicciones temporales, simples y prácticas, directamente comprobables y aplicables, economizando tiempo y recursos.

Objetivo Definir para Medellín el alcance del concepto y de la estrategia de Ciudad Saludable.Material y Métodos Estudio mixto con revisión de literatura, análisis documental y participación de actores.Resultados En la construcción del concepto se llega a “una ciudad para vivir más y mejor” y se identifican quince características atribuidas a Medellín Ciudad Saludable. La población califica la situación actual como regular y da mayor importancia a las características de medio ambiente, seguridad, acceso a servicios de salud, vivienda y empleo. Aun así, la ciudad presenta avances y esfuerzos importantes para ser reconocida como Ciudad Saludable, pues mantiene programas y proyectos en estas y otras características que contribuyen a elevar el estado de salud.Discusión La construcción de una Ciudad Saludable es particular a cada contexto y en cualquier caso demanda la combinación de trabajo técnico y participación ciudadana en aras de elaborar su propio imaginario e identificar prioridades. En el caso de Medellín, es necesario asumir la estrategia de manera sistemática para que se mantenga en el futuro y hacer explícitas metas

Objetivo El objetivo del estudio fue verificar: el cumplimento de las metas de tratamientos en las clínicas dentales especializadas (CDEs) en la Región Sur de Brasil y, los factores asociados a los procesos de trabajo.Método El estudio fue exploratorio transversal. Para la recolección de datos fueron consultadas las bases del datos provenientes de  DATA/SUS, CNES, SIOSP, IBGE y fue enviado un cuestionario semiestructurado para los gestores de las CDEs. Para comprobar  la asociación de los factores con el cumplimento de las metas de las CDEs se realizó el test de Kruskal Wallis.Resultados Fueron analizados 936 meses de tratamiento ambulatorio distribuidos en las 78 CDEs y la tasa de respuestas de los cuestionarios fue de 68%. Las variables: estado de Paraná, municipios con número de ciudadanos de 0-50 mil/hab, el cuarto quintil de los gastos totales en salud y PIB per cápita fueron asociados con el cumplimento de las metas de los procedimientos de periodoncia y, el tipo II de CDE presentó asociación con el cumplimento de las metas de los procedimientos básicos.Discusión El análisis de las variables que pueden estar asociadas al tratamiento ambulatorio en las CDEs es fundamental para comprobar tanto los problemas de acceso de los habitantes como la aplicabilidad de los recursos públicos en el área de la salud.Conclusiones El estudio indica un bajo cumplimento de las metas de tratamiento de las CDEs, entretanto apunta que pueden haber factores importantes asociados al mayor número de meses en las metas cumplidas.
Teoria de Utilidade Epistêmica e o Argumento da Acurácia a favor do Probabilismo
Authors: Neiva André
Published: August 2017

Diferente dos argumentos tradicionais na literatura em epistemologia formal, o argumento da acurácia gradacional de James Joyce fornece uma justificação epistêmica do probabilismo. O seu argumento pretende mostrar que funções probabilísticas de graus de crença têm maior grau de acurácia, ou menor grau de inacurácia, do que qualquer outra função não probabilística de crença gradual. Neste artigo, reconstruímos e examinamos a sua proposta, que é definida como uma estratégia de utilidade epistêmica. Também fornecemos uma aplicação de uma determinada medida de inacurácia (Brier score) sobre diferentes funções de crença gradual. Por fim, discutimos alguns problemas que foram levantados contra a versão original do argumento de Joyce e concluímos com algumas sugestões de resposta a esses problemas.
A dialética do ser-nada-devir: desdobramentos da ciência da lógica de Hegel
Authors: Ericksen Lauro
Published: August 2017

O trabalho tem o escopo geral de mostrar os aspectos mais relevantes dos desdobramentos filosóficos contidos na “Ciência da Lógica” de Hegel, enfocando-se nos elementos dialéticos da sistemática do ser-nada-devir. Seus objetivos específicos são: identificar os conceitos de cada unidade lógica, descrevendo suas funções no entendimento onto-metafísico da realidade; expor a unidade e a oposição contidas nos conceitos mínimos de ser e de nada; e escrutinar as possibilidades do pensamento sobre a realidade extraídas das formas categoriais da dialética do ser, do nada e do devir. Metodologicamente, segue-se a assertiva hegeliana da busca pelo puro ser, como uma noção mínima de uma categoria lógica que possibilita a assunção de uma nova premissa básica de assentamento da filosofia em sua conceituação lógica. Como resultado, tem-se que a verdade desse sistema dialético pode ser compreendida como o trespasse lógico entre o ser e o nada em direção ao devir, a essência de qualquer posicionamento metafísico. Conclui-se que as contribuições de Hegel para a filosofia e para a construção de uma ciência da lógica moderna são bastante coesas e sólidas, de modo que estabelecem uma base importante para um novo implemento filosófico baseado na compreensão lógica da realidade metafísica.
A intencionalidade da vontade como faculdade de ação no “De Libero Arbítrio” de Agostinho
Authors: Jeske Vahl Matheus
Published: August 2017

A teoria agostiniana da vontade é desenvolvida dentro da elaboração da estrutura fundamental de sua ética, onde o problema acerca da origem do mal e da responsabilidade humana surgem como motivação. Agostinho apresenta a vontade como uma faculdade ativa da alma pela qual o homem exercendo sua liberdade, projeta-se no mundo. Embora seja neutra, ela é suscetível às influências tanto das sensações produzidas pelas relações do homem com o mundo objetivo, quanto do que lhe é transmitido pela razão. Através do entendimento e discernimento destas influências psicológicas, o homem age tanto construindo sua identidade como reduzindo sua condição ontológica.
Três dogmas da metodologia metafísica
Authors: Gaboardi Gregory
Published: August 2017

Neste artigo Jessica Wilson examina os modos pelos quais pode haver progresso filosófico e o que pode afetar esse progresso ou explicar seu estágio atual, particularmente na área da metafísica. Wilson identifica e critica três posições que estariam sendo mantidas de modo dogmático por metafísicos e, com isso, prejudicando o progresso na área: a defesa do Ditado de Hume, a defesa de que a composição dos objetos é devidamente caracterizada pela mereologia clássica e a defesa de que disputas metaontológicas são disputas sobre a semântica de quantificadores. Wilson conclui que, embora persistam algumas tensões profundas envolvendo a possibilidade do progresso filosófico e as posições criticadas possam ser justificadas, atualmente a defesa dessas posições é dogmática e está prejudicando o progresso da metafísica.
