Resumen

In 1986, the UN ECE established the International Cooperative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (hereinafter ICP Forests) to respond on the growing concern about forest damage caused since the beginning of eighties by air pollution load. Pan-European grid of the (ICP Forests) monitoring plots represents one of the most important systems of forest ecosystems assessing and checking. The Czech Republic is unfortunately well known due to this problem and so the country joined ICP Forest Programme since the very beginning. The paper presents general information on Czech forest stand condition that gained through various methods in the past as well as in the frame of ICP Forests. The participation in the International Cooperative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (ICP Forests) represents a contribution of the EU candidate country to the fulfillment of the Reg. (EEC) No. 3528/86. However it seems that effects and importance of air pollution are decreasing, a lot of new stress situations exists and there is a need for continuing the programme.

Resumen

Forest health status in Europe is assessed by the International Cooperative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (ICP Forests). Established by the Convention on Long-Range Transboundary Air Pollution (CLRTAP) under the United Nations Economic Commission for Europe (UNECE), the ICP Forests has been monitoring forest condition in close cooperation with the European Commission (EC) for 20 years. The present paper describes the latest results of the deposition measurements on permanent monitoring plots and of the extensive defoliation sample survey. The findings reveal marked spatial patterns in bulk and throughfall depositions of nitrate (N-NO3-), ammonium (N-NH4+), and sulfate (S-SO42-), as well as an obvious decrease in bulk and throughfall deposition of sulfate. Latest analyses of defoliation data confirm previous results, indicating a high correlation with weather extremes.

Resumen

In order to make conclusions related to the selection of the most appropriate improvement measures, it is necessary to define the condition of forests through monitoring their health state. ICP for Forests Monitoring deals with human factors (mainly air pollution) and biotic factors that impair vitality and hinder the development of forest ecosystems in Europe and Serbia. Since broadleaved forests experience stronger attacks of plant diseases and pests, they have more severe defoliation. Beech is the most common broadleaved species at the ICP sample plots in Serbia. It is followed by oak species - sessile oak, Turkey oak and Hungarian oak. The largest number of insect species develop on the assimilation organs of forest trees. The paper presents the most common species of defoliators detected at SP in Serbia in 2021.

Resumen

Increased Intracranial Pressure (ICP) is a serious and often life-threatening condition. If the increased pressure pushes on critical brain structures and blood vessels, it can lead to serious permanent problems or even death. In this study, we propose a novel regression model to forecast ICP episodes in children, 30 min in advance, by using the dynamic characteristics of continuous intracranial pressure, vitals and medications during the last two hours. The correlation between physiological parameters, including blood pressure, respiratory rate, heart rate and the ICP, is analyzed. Linear regression, Lasso regression, support vector machine and random forest algorithms are used to forecast the next 30 min of the recorded ICP. Finally, dynamic features are created based on vitals, medications and the ICP. The weak correlation between blood pressure and the ICP (0.2) is reported. The Root-Mean-Square Error (RMSE) of the random forest model decreased from 1.6 to 0.89% by using the given medication variables in the last two hours. The random forest regression gave an accurate model for the ICP forecast with 0.99 correlation between the forecast and experimental values.

Resumen

The paper describes the methodology for determining LAI according to the ICP forest methodology, where hemispherical photographs were taken on a network of fixed points placed on the surfaces of three Sample plots Level II. Hemispherical photographs were processed by the Hemisfer software package. The data obtained by image processing were entered into the ICP Forests database. The obtained LAI values represent the response to the state of vegetation under the influence of different ecological conditions as well as anthropogenic influences, and will be the part of future annual monitoring at Sample plots of the Level II points.

Resumen

The vitality of forests depends on environmental conditions and a great number of abiotic factors, such as climatic characteristics, atmospheric deposition, forest fires, direct atmospheric impacts. Nevertheless, abiotic agents are group of the most important factor threatening the trees sampled and monitored for more than a decade and a half in continuity. Therefore, further analysis can provide different trends of their direct effects and degrees of their out-turn. International program for further and more detailed monitoring of the forest condition in the Republic of Serbia (ICP Forests), which is carried out on both Level I and Level II(Mokra Gora and Crni Vrh) sample plots, will enable scientists to determine the vitality of forests both at the local and at the regional level. Results are vitality and health state of the forest ecosistems with emphasis on abiotic factors.

Resumen

Project of forests condition monitoring (ICP Forests) operates as an international European project in which, on grid of ICP sample plots (bioindication points) condition of forests has been monitored annually in continuity, including recording data on defoliation with evidencing any damage to the trees. The main goal of the program is monitoring of condition of forests on a permanent, representative surfaces, arranged in a systematic grid distributed on the territory of of Europe. This paper analyzes the data on defoliation as part of the results of the forest conditions monitoring on ICP sample plots on the territory of the Republic of Serbia, in the period 2012-2016. The assessment of defoliation is performed on the experimental fields regardless of the cause of loss of leaves, because the results are not aimed to determinate the cause-and-effect relationships, but only to represent the state of defoliation on this study sample plots in the researched period. Assessment and analysis of the degree of crown defoliation has been presented for most common tree species as the most noticeable crown health indicators. Linking these results with other indicators of environmental conditions will provide more concrete informations, and draw conclusions about the vitality of the plants depending on ambient conditions.

Resumen

Abstract This review paper summarises the development of forest monitoring in Europe and in Slovakia. Since 1986 Forest Research Institute has been performing monitoring activities at the systematic grid of 16×16 km on permanent monitoring plots of Level I (extensive monitoring) and since 1995 on 9 plots of II. Level (intensive monitoring), which is closely connected with programme ICP Forests and PMS Forests. However, during 1991-1992 monitoring on 1189 plots in the grid of 4×4 km in Slovakia was done by Lesoprojekt Zvolen, which was repeated during the last 10 years as a part of LHP (every year 1/10 territory). This paper describes briefly also surveys and monitoring activities of different monitoring systems, parameters, methods and the perspectives of monitoring of the forest condition

Resumen

It was the late summer of 2003 when we first travelled to Sardinia to set up traps in the forest of Marganai, an area owned by the regional administration, in the south-western part of the island. Our Centro Nazionale per lo Studio e la Conservazione della Biodiversità Forestale in Verona—a research institute of the Italian State Forestry Service—had been entrusted with the assessment of arthropod diversity in permanent monitoring sites of the ICP Forests network, a European body for long-term research in forest ecosystems (Mason et al. 2006). The project included a total of twelve forests in Italy, and we were setting up a standard sampling design at each site.

Resumen

During the last decades, forest ecosystems have been strongly exposed to the effect of different harmful pollutants, especially from the atmosphere. Harmful substances from the air, in addition to the direct effect on forest trees, also deposit in the soil, and have an adverse effect on soil chemistry and pedogenetic processes. The results of previous studies in Serbia (Kadovic, Knezevic, 2002, 2004) show some specificities regarding the accumulation and migration of heavy metals in the soil. The highest concentrations were found in the layers of forest litter and in the surface organo-mineral horizons. This paper presents the results of the study of heavy metal contents (Zn, Mn, Cu, Fe, Cd, Pb, Ni and Cr) in the organic horizon (forest litter) of beech forests in Serbia. The study of the heavy metal content in the organic horizon (forest litter) is very significant primarily in the aim of monitoring the trend of their migration through the soil profile and the effect on the soil properties and genesis. The soil quality in beech forests in Serbia was assessed within the Project ICP Forest, Level I, by the methodology UN/ECE-EC, 2000.

The Sierra Ancha International Cooperative Program on Assessment and Monitoring of Air Pollution Effects on Forests study site or (SAEF-ICP II) is part of an international network of cooperative forest monitoring sites spread throughout Europe and the United States. The United Nations Economic Commission for Europe established the ICP II network in 1985 to monitor long-term effects of transboundary air pollution. The Sierra Ancha Experimental Forest was chosen to be a part the U.S.’s network because it is the southernmost Experimental Forest in the contiguous U.S., and because it is downwind from a major metropolitan area, Phoenix, Arizona. The site monitoring includes forest overstory growth, crown condition, foliar chemistry, understory vegetation, litterfall, soil chemistry meteorology, ozone, and deposition. This paper provides an overview of the ICP forest network, and discusses the research currently underway at the Sierra Ancha ICP II site. An overview of the challenges encountered while implementing ICP Level II monitoring will also be included.

O uso abusivo de drogas tornou-se um problema global que tem graves consequências, tanto para os usuários de drogas quanto para a sociedade. A determinação dos constituintes inorgânicos de drogas ilícitas pode ser usada para indicar a sua qualidade (pureza e concentração de outros componentes das drogas). Além disso, variações na composição e pureza da droga pode ser usada para formular hipóteses sobre a estrutura do mercado ilegal de drogas, principalmente em relação a sua distribuição. Foram analisados cinquenta e duas amostras de cocaína de rua que foram apreendidas em diferentes regiões do Estado do Espírito Santo Brasil. O pré-tratamento das amostras consistiu em digerir 0,1 g da amostra com 6 mL de HNO3 5% v/v em um forno de micro-ondas com sistema fechado e posterior diluição da amostra para 15 mL. Espectrometria de emissão ótica com plasma indutivamente acoplado (ICP OES) ou Espectrometria de massa com plasma indutivamente acoplado (ICP-MS) foram então usadas para determinar as concentrações de Al, Ca, Cu, Fe, Mn, Mg, Zn, Mo, Co, Pb e P nestas amostras. O procedimento foi verificado através de testes de recuperação em duas concentrações (50 e 100 μg L-1). Os dados resultantes foram depois analisados estatisticamente. Usando a Análise Hierárquica de Cluster (HCA) foi possível obter uma diferenciação entre as regiões de apreensão. Correlações de Pearson permitiram correlacionar as concentrações dos elementos com os compostos químicos que são utilizados na produção e adulteração da cocaína. Boxplot confirmou a distinção entre as regiões de apreensão.

Resumen

The effect of ice damage on loblolly pine (Pinus taeda) plantations in the Piedmont region of Virginia was examined to discover if management decisions can minimize net present value losses. A simulation approach was used for the analysis. Loblolly pine plantations were simulated using the growth and yield model, Trulob. Ice damage was factored into the model using prediction equations from a previous study. A decision tree framework was used to determine which management plans resulted in the highest net present value. The results show that ice storms can cause significant losses to the net present value of loblolly plantations. In most instances changing management plans could not minimize losses. In situations where altering management plans can result in higher net present values if ice occurs, landowners should also be aware of the suboptimal net present value they will be returned if these plans are followed and no ice storms occur.

Considerando o grande aumento das mortes violentas, principalmente no Brasil, e a crescente utilização de armas de fogo para cometer tais crimes, a balística forense associada a entomologia forense se tornam grandes aliadas nas investigações criminais. As concentrações de chumbo (Pb), bário (Ba) e antimônio (Sb), caracerísticos de resíduos de disparo de arma de fogo (GSR GunShot Residue), foram monitoradas em larvas de moscas (imaturos de Chrysomya albiceps). As coletas sucederam em um cadáver de porco, do sexo feminino, morto com três disparos realizados com pistola Taurus®, calibre .40 a curta distância (entre 25 e 40 cm), sendo dois disparos na região cefálica e um na região abdominal, em um período de 2 a 12 dias após a morte, durante o inverno, sob a influência da chuva e alta umidade relativa do ar. Dessa forma, o objetivo deste trabalho foi avaliar a aplicabilidade da técnica de espectrometria de emissão óptica com plasma indutivamente acoplado (ICP OES) para a quantificação de Pb, Ba e Sb proveniente de GSR em larvas cadavéricas num ambiente não controlado, simulando um caso real de homicidio. Foi possível detectar e quantificar os três elementos traço de interesse pela técnica proposta, onde as concentrações mantiveram-se praticamente constante durante o estágio de putrefação. Concentrações mínimas (Pb = 382,26 μg·L-1; Ba = 140,50 μg·L-1; Sb = 39,18 μg·L-1) e as concentrações máximas (Pb = 522,66 μg·L-1; Ba = 190,30 μg·L-1; Sb = 56,14 μg·L-1) foram encontradas durante o terceiro e quinto dia post mortem, respectivamente. As amostras também foram analisadas pelo teste colorimétrico usando rodizonato de sódio (reação Feigl-Suter) apresentando resultado negativo para todas as soluções obtidas a partir dos imaturos de Chrysomya albiceps. Uma hipótese para a constância nas concentrações dos três elementos, é que de acordo com a literatura, as larvas da espécie Chrysomya albiceps podem exercer papel como predadora intraguilda de larvas de outras espécies de Dípteras, além de realizar canibalismo. Sendo assim, a técnica de ICP OES apresenta maior sensibilidade na quantificação frente ao convencional teste colorimétrico, mostrando ser uma técnica aplicável a esse tipo de matriz. É importante notar que o desenvolvimento tal pesquisa é de grande importância forense e é uma técnica que apresenta potencial para aplicação futura em casos de morte violenta, em que a vítima se encontra em decomposição inicial, moderada e avançada. Nesse aspecto, o desenvolvimento e aperfeiçoamento de metodologias eficientes são de grande relevância para a elucidação de crimes.

Resumen

This study compared the plantar force distribution between forward ice hockey skating and treadmill skating. Four varsity hockey players from McGill University (age = 22.1 +/- 1.2 years, height = 1.8 +/- 0.1 m, mass = 82.2 +/- 8.6 kg) skated on ice surface and on a specialized treadmill at three velocities (22, 24 and 26 +/- 0.5 km/hr). Results showed higher plantar forces were seen during treadmill skating prior to push off and this discrepancy was due to consistently larger forces in the fore region of the foot. This phenomenon was speculated to be the result of differences in skate stability during ice and treadmill skating. With respect to the loading dynamics, the heel region was the same during ice and treadmill skating.

Resumen

Knowledge is one of the most central driving forces in today’s economy. Thus, organizations need to recognize knowledge as a valuable resource and develop tools for tapping into the collective intelligence and create a greater organizational knowledge base. However, to stay competitive on today’s global marketplace actors must collaborate and share knowledge across organizational boundaries. Companies must therefore consider barriers to knowledge sharing. While the importance of knowledge sharing across organizational boundaries has been highlighted, researchers emphasize that an interesting factor to examine in further research is the role of Information and Communication Technology (ICT) to mitigate barriers for knowledge sharing. The purpose with this study is to explore in what way ICT may be used to mitigate barriers for knowledge sharing between individual forest landowners and forest companies within the Swedish forest industry. The study is divided into two research questions: (1) What critical barriers for knowledge sharing exist between individual forest landowners and forest companies within the Swedish forest industry? and (2) In what way may ICT be used to mitigate barriers for knowledge sharing between individual forest landowners and forest companies. To answer the research questions, a multiple case study consisting of 23 interviews was conducted with forest consultants, forest landowners and forest companies. In addition to prior literature regarding individual, organizational and technology barriers, our study emphasize that firms also must consider inter-organizational barriers to knowledge sharing. By mapping the most critical barriers according to individual forest landowners and forest companies, our study assess in what way ICT may be used to mitigate these barriers. In addition, the study contributes with an emerging framework for managers to visualize and prioritize barriers to mitigate, which is useful when planning and evaluating knowledge management activities.

Resumen

The establishment of the state of the massif by a diagnosis on different forest plots is part of a project of monitoring and silvicultural management. The purpose of this study is to assess the health status of the Ouled Bechih forest. The methodology used was the visual assessment of the tree crown of the dominant species (i.e. Quercus suber and Quercus canariensis) according to the protocols DEPEFEU, DEPERIS and ICP Forests. These protocols were selected for adoption based on field observations and their applicability in record time. The results obtained indicate that the health status of the trees within the studied plots is declining. The DEPEFEU value index shows an average of 1.75 for Quercus suber and 2.6 for Quercus canariensis while the DEPERIS has an average level of 2.36 Q. suber in and 3.37 in Q. canariensis. ICP Forests has also contributed to providing clearer information on the consequences of this health situation by deducting an average visibility rate of 1.20 and 2.63; social status of 1.17 and 3.11 and competition of 1.11 and 2.49 for Q. suber and Q. canariensis respectively. In general, the health status of the tree crown is average and almost adapted to the environmental conditions. In contrast, the carrying capacity of biodiversity is low and needs to be improved.

Resumen

The study aims to determine the growth and health response of Betula pendula and Betula pubescens growing in the forest sites of different soil fertility and humidity in Lithuania. The analysed data was collected under the Forest Monitoring Level I of ICP-Forests program. Lithuanian forest sites classification described by Vaičys et al. (2006) was used for the data analyses. The obtained results show that better condition of B.pendula was recorded for the birch trees growing in more humid sites and for B. pubescens – growing in the dryer sites. Also it was found that the lowest defoliation was typical for dominant and codominant trees and it did not depend on site humidity. The highest data variation of B. pendula stem diameter between forest sites of different humidity were found in the birch stands up to 50 years old. For younger B. pendula trees, higher diameter was recorded in more humid sites compared to the less humid sites. The stem diameter of B.pubescens trees was higher in the sites with normal moisture and temporary overmoistured soils compared to those growing in the permanently overmoistured and peatland soils.

Resumen

The Geological Survey of Canada undertook a mineral resource assessment for a proposed national park in northern Canada (~ 33,500 km2) spanning the transition from boreal forest to barren lands tundra. Bedrock geology of this region is complex and includes the Archean Slave Craton, the Archean and Paleoproterozoic Rae domain of the Churchill Province, the Paleoproterozoic Thelon and Taltson magmatic-tectonic zones, and the Paleoproterozoic East Arm sedimentary basin. The area has variable mineral potential for lode gold, kimberlite-hosted diamonds, VMS, vein uranium and copper, SEDEX, as well as other deposit types. A comparison of analytical methods was carried out after processing the field collected samples to acquire both the &lt; 2 mm and for the &lt; 0.063 mm size fractions for 241 surficial sediment (till) samples, collected using a 10 x 10 km grid. Analytical methods comprised: 1) aqua regia followed by ICP-MS analysis, 2) 4-acid hot dissolution followed by ICP-ES/MS analysis, 3) lithium metaborate/tetraborate fusion methods followed by ICP-ES for major elements and ICP-MS for trace elements and, 4) portable XRF on dried, non-sieved sediment samples subjected to a granular segregation processing technique (to produce a clay-silt proxy) for seventeen elements (Ba, Ca, Cr, Cu, Fe, K, Mn, Ni, Pb, Rb, Sr, Th, Ti, U, V, Zn, and Zr) Results indicate that pXRF data do not replicate exactly the laboratory 4-acid and fusion data (in terms of precision and accuracy), but the relationship between the datasets is systematic as displayed in x-y scattergrams. Interpolated single element plots indicate that till samples with anomalies of high and low pXRF concentration levels are synonymous with high and low laboratory-based analytical concentration levels, respectively. The pXRF interpolations thus illustrate the regional geochemical trends, and most importantly, the significant geochemical anomalies in the surficial samples. These results indicate that pXRF spectrometry for a subset of elements is comparable to traditional laboratory methods. pXRF spectrometry also provides the benefit of rapid analysis and data acquisition that has a direct influence on real time sampling designs. This information facilitates efficient and cost-effective field projects (i.e. where used to identify regions of interest for high density sampling), and to prioritize samples to be analyzed using traditional geochemical methods. These tactics should increase the efficiency and success of a mineral exploration and/or environmental sampling programs.

Resumen

Use of visual methods plays a significant role in learning. ICT allow us to create electronic educational resources in a new format and with new opportunities. The study of their didactic possibilities, forms and methods of their application is a topical issue. Simulation, virtualization, gamification requires new knowledge about their application, and therefore, the problem of training future teachers to use them is an urgent and important part of training. In this article modern achievements in the use of serious games in education were investigated and analyzed, the possibilities of using virtual worlds in education were considered, the recommendations for the practical training of future teachers to use them were developed. In practice, the effectiveness of the use of virtual tools in education has been tested. A pedagogical experiment has been launched to identify the effectiveness of gamification in the realities of education in Ukraine.

Texto completo

Resumen

Ice fog events, which occur during the Arctic winter, result in greatly decreased visibility and can lead to an increase of ice on roadways, aircraft, and airfields. The Fairbanks area is known for ice fog conditions, and previous studies have shown these events to be associated with moisture released from local power generation. Despite the identified originating mechanism of ice fog, there remains a need to quantify the environmental conditions controlling its origination, intensity, and spatial extent. This investigation focused on developing innovative methods of identifying and characterizing the environmental conditions that lead to ice fog formation near Fort Wainwright, Alaska. Preliminary data collected from December 2019 to March 2020 suggest that ice fog events occurred with temperatures below −34°C, up to 74% of the time ice fog emanated from the power generation facility, and at least 95% of ice particles during ice fog events were solid droxtals with diameters ranging from 7 to 50 μm. This report documents the need for frequent and detailed observations of the meteorological conditions in combination with photographic and ice particle observations. Datasets from these observations capture the environmental complexity and the impacts from energy generation in extremely cold weather conditions.

Resumen

Sliding friction on ice and snow is characteristically low at temperatures common on Earth’s surface. This slipperiness underlies efficient sleds, winter sports, and the need for specialized tires. Friction can also play micro-mechanical role affecting ice compressive and crushing strengths. Researchers have proposed several mechanisms thought to govern ice and snow friction, but directly validating the underlying mechanics has been difficult. This may be changing, as instruments capable of micro-scale measurements and imaging are now being brought to bear on friction studies. Nevertheless, given the broad regimes of practical interest (interaction length, temperature, speed, pressure, slider properties, etc.), it may be unrealistic to expect that a single mechanism accounts for why ice and snow are slippery. Because bulk ice, and the ice grains that constitute snow, are solids near their melting point at terrestrial temperatures, most research has focused on whether a lubricating water film forms at the interface with a slider. However, ice is extremely brittle, and dry-contact abrasion and wear at the front of sliders could prevent or delay a transition to lubricated contact. Also, water is a poor lubricant, and lubricating films thick enough to separate surface asperities may not form for many systems of interest. This article aims to assess our knowledge of the mechanics underlying ice and snow friction.

Resumen

Peculiar features of digital environment include: integration of ICTs; use of local and global networks and resources; support and development of qualitatively new technologies of information processing; active use of modern means, methods and forms of teaching in the educational process. The organization of activities in terms of digital learning environment provides appropriate changes in the interaction between subjects of the educational process. Today, means and technologies of the information and communication networks (ICNs), in particular the Internet, which custom and operational-procedural properties were changed at the initial stage from closed local to open ones at present, become widespread. The development of ICNs (from closed local to open ones) changes the typology of learning environments. The following models of learning environments, which widely use ICT and ICN tools (with basic features that characterize them) are distinguished: using the local communication network for presentation of educational information; using the local communication network and open network resources; using open network resources; for independent use of open network resources directly in the classroom by a student; for use of open network resources by a student in the process of independent learning activity; for use by a student educational resources, specially created by a teacher, as well as resources of an open networks in his independent learning activity.
