Eduard Wiiralt’s Unknown Matchbox Picture from Vienna, 24 December 1944
Authors: Raudsepp Anu
Published: October 2017

The main objective of the article is to introduce the matchbox picturecalled Girl Looking Up in Prayer created in Vienna on 24 December1944 and the bookplate based thereon that was produced in Estoniain 1960. In addition, based on archival sources, an explanation isprovided of the reception of Eduard Wiiralt’s work in occupiedEstonia until the end of the 1950s.Despite the common belief that Wiiralt was totally ignored duringthe Stalinist period in Estonia, he was still included in the art historycurricula of the official schools of higher education. Many of thestudents at that time were soon actively helping to restore publicrecognition to Wiiralt, which occurred after the artist’s death in1954. The introduction of Wiiralt’s oeuvre in Estonia was precededby an exhibition in Moscow in 1956. It is possible that the matchboxpicture that was sent to Estonia in a letter on 15 February 1959 wasnot the first original post-war work by Wiiralt to arrive here. Theowner had the picture made into a bookplate that was produced ina large run. Eduard Wiiralt himself is known to have made sevenbookplates between 1918 and 1936.It is also possible to document the changes that have occurred insociety and the moods of the times through art. From the matchboxpicture that Wiiralt drew on Vienna on Christmas Eve in 1944, theyear that Estonia lost its independence, one can surmise the artist’sbelief and hope that his beloved Estonia would someday becomefree again.
Correlation of near-Earth proton enhancements >100 MeV with parameters of solar microwave bursts

Published: October 2017

We analyze the relations between various combinations of peak fluxes and fluences of solar microwave bursts at 35 GHz recorded with the Nobeyama Radio Polarimeters during 1990–2015, and corresponding parameters of proton enhancements with E>100 MeV exceeding 0.1 pfu registered by GOES monitors in near-Earth environment. The highest correlation has been found between the microwave and proton fluences. This fact reflects a dependence of the total number of protons on the total duration of the acceleration process. In the events with strong flares, the correlation coefficients of proton fluences with microwave and soft X-ray

fluences are higher than those with speeds of coronal mass ejections. The results indicate a statistically larger contribution of flare processes to acceleration of high-energy protons. Acceleration by shock waves seems to be less important at high energies in events associated with strong flares, although its contribution probably prevails in weaker events. The probability of a detectable proton enhancement was found to directly depend on the peak flux and duration of a microwave burst. This can be used for diagnostics of proton enhancements based on microwave observations.
Drift-compression waves propagating in the direction of energetic electron drift in the magnetosphere
Authors: Костарев Данила , Kostarev Danila , Магер Павел , Mager Pavel
Published: October 2017

As shown within the gyrokinetic framework, drift-compressional waves can propagate in the magnetosphere in the direction of energetic electron drift. The plasma is assumed to be composed of cold particles with an admixture of hot protons with a Maxwell distribution and electrons with an inverted distribution. The conditions of existence of such waves and their intensification due to resonance interaction with energetic electrons (drift instability) have been de- termined. The results can be helpful in interpreting observation of wave phenomena in the magnetosphere with frequencies in the range of geomagnetic pulsations Pc5 and below.
Space weather impact on radio device operation
Authors: Бернгардт Олег , Berngardt Oleg
Published: October 2017

This paper reviews the space weather impact on operation of radio devices. The review is based on recently published papers, books, and strategic scientific plans of space weather investigations. The main attention is paid to ionospheric effects on propagation of radiowaves, basically short ones. Some examples of such effects are based on 2012–2016 ISTP SB RAS EKB radar data: attenuation of ground backscatter signals during solar flares, effects of traveling ionospheric disturbances of different scales in ground backscatter signals, effects of magnetospheric waves in ionospheric scatter signals.
Efficient Simulation of Clustering Jumps with CIR Intensity
Authors: Dassios Angelos , Zhao Hongbiao
Published: October 2017

We introduce a broad family of generalised self-exciting point processes with CIR-type intensities, and we develop associated algorithms for their exact simulation. The underlying models are extensions of the classical Hawkes process, which already has numerous applications in modelling the arrival of events with clustering or contagion effect in finance, economics, and many other fields. Interestingly, we find that the CIR-type intensity, together with its point process, can be sequentially decomposed into simple random variables, which immediately leads to a very efficient simulation scheme. Our algorithms are also pretty accurate and flexible. They can be easily extended to further incorporate externally excited jumps, or, to a multidimensional framework. Some typical numerical examples and comparisons with other well-known schemes are reported in detail. In addition, a simple application for modelling a portfolio loss process is presented.

Multi-Priority Online Scheduling with Cancellations
Authors: Wang Xinshang , Truong Van-Anh
Published: October 2017

We study a fundamental model of resource allocation in which a finite amount of service capacity must be allocated to a stream of jobs of different priorities arriving randomly over time. Jobs incur costs and may also cancel while waiting for service. To increase the rate of service, overtime capacity can be used at a cost. This model has application in healthcare scheduling, server applications, make-to-order manufacturing systems, general service systems, and green computing. We present an online algorithm that minimizes the total cost due to waiting, cancellations and overtime capacity usage. We prove that our scheduling algorithm has cost at most twice of an optimal offline algorithm. This competitive ratio is the best possible for this class of problems. We also provide extensive numerical experiments to test the performance of our algorithm and its variants.
A DICOTOMIA FATO/VALOR E A SUA IMPORTâNCIA PARA A COMPREENSÃO DA VERDADE NO PROCESSO
Authors: Costa Rafael de Oliveira
Published: October 2017

A partir da concepção de que o método se apresenta como caminho para alcançar a verdade, o intérprete passou a inverter o processo hermenêutico, para adequar a ordem jurídica ao seu sentido subjetivo. O presente trabalho tem como objetivo analisar a dicotomia fato/valor, tomando como marco teórico a obra de Hilary Putnam, objetivando (re)construir a concepção de verdade no âmbito processual civil. Trata-se de pesquisa que faz uso de dados de natureza secundária (entendimentos doutrinários), permitindo concluir que a verdade alcançável no processo será sempre uma só: nem material, nem formal, mas processual (convicção de verdade), decorrente da mais ampla instrução probatória e da participação do jurisdicionado com efetiva capacidade de influenciar o julgador, acabando por legitimar o próprio conteúdo da decisão (juridicidade).
AS CONTRIBUIÇÕES DE NORBERTO BOBBIO E DE LUIGI FERRAJOLI À SOBERANIA DE HANS KELSEN
Authors: Demarchi Clovis , Wloch Fabrício
Published: October 2017

Este artigo científico investiga o conceito de Soberania do ponto de vista de grandes autores contemporânos, Kelsen, Ferrajoli e Bobbio. A importância do tema é estabelecer os aprimoramentos trazidos por Bobbio e Ferrajoli ao conceito de Soberania originalmente estudado por Kelsen. Na primeira parte caracterizou-se os elementos identificadores da Soberania. Na segunda tratou-se da Soberania vista pelo austríaco Hans Kelsen, tida como inerente ao poder do Estado e como manifestação da validade e eficácia do ordenamento jurídico, que pode ser limitado apenas pelo Direito Internacional. Na terceira parte foi trazida a visão do italiano Norberto Bobbio que destaca a contradição entre Soberania e constitucionalismo e democracia. Na quarta descreveram-se os aspectos da Soberania estatal do ponto de vista do também italiano Luigi Ferrajoli que aborda o tema de modo histórico e bélico. Na quinta parte correlacionaram-se as três posições de modo a distinguir a melhor via para se construir um novo conceito adaptado à modernidade e inspirado no sociólogo e humanista Edgar Morin. No que se refere à Metodologia, o trabalho foi desenvolvido em base lógica indutiva. A pesquisa foi bibliográfica e documental.

This study aimed to analyse the endogenous levels of free polyamines putrescine (Put), spermidine (spd) and spermine (spm) under the effect of 8-HQC (8-hydroxyquinoline citrate) and chlorine during cold storage of bird-of-paradise floral scapes. Flowers were selected, labelled and randomly distributed in recipients for postharvest trials. The base of flower scapes was immersed with pulsing treatments (Control, 100 chlorine, 250 or 500 mg L-1 8-HQC) for 48 h, thereafter, stored at 10.5 °C and 90% relative humidity for a period of 12 days. Flower parts were sampled for polyamines analysis at day 0, 4, 8 and 12 days during storage. All samples had higher Put levels than the control. Treatment with 500 mg L-1 8-HQC showed the highest Spd levels in bracts, while chlorine treatment had the highest Spm levels in stems.

MENYIKAPI PLURALISME AGAMA PERSPEKTIF AL-QUR’AN
Authors: Andi Azhari , Fadilla Ezi
Published: October 2017

Nowadays, the discourses of religion pluralism is one of the frequently-discussed issue among muslim. This case appears along with the emergence of books, works, writings in the mass media, congress, seminars, discussions, and dialogue which are focusing on the religion pluralism. One of the factors causing the emergence of this discourse is a number of conflicts that happened among different religious adherents which was often began by an excessive truth claim. The discourse presented in this paper aims to create harmony life and peace among different religion adherents. Al-Qur’an both admits the existence of other religions and commands its followers to live in harmony as well as respect each other. Islam is “rahmah lil ’ālamīn”, but yet the reality that happens in muslim world is not in line with the ideality. So the question arises in our minds; where is Islam as rahmah lil ’ālamīn? the fact is there are still many muslim who can’t wisely face the plurality as it has been taught by the Qur’an. So how is the Qur’anic guidance to face the plurality? Based on this reason, this article would like to discuss on the Qur’anic guidance in facing the religion pluralism using descriptive-analysis method.
POTRET HARMONI KEHIDUPAN BERAGAMA: Studi Komperatif Relasi Islam-Buddha di Desa Tlogowungu, Kaloran, Temanggung dan Desa Blingoh, Donorojo, Jepara
Authors: Yusuf Mohamad
Published: October 2017

The inter-religious harmony is not a rare thing in Indonesian society, there are a lot of practice at the grassroots level, which show that the Indonesian people are able to build religious harmony. However, due to the rise of religiously motivated violent incidents, both the case of intra-religion and inter-religious, and global-scale violence, the peaceful images of Islam are slowly replaced by the religious issues that are less encouraging. Based on that irony, this study tries to show a portrait of interfaith harmony between Islam and Buddhism in two different places; Tlogowungu, Temanggung and Blingoh, Jepara. Although both remain predominantly Muslim region, but the region becomes the centre of Buddhist people which is growing rapidly. This study shows that religious harmony between Muslims and Buddhists has a long historical roots. In addition to each doctrinal aspects of religion, the driving force of harmony also came from the role of local wisdom that exist in each region. Muslims and Buddhists are also equally establish relations of coexistence between religions patterned or mutually support the existence of each religion and cooperative patterns or work together in real.
HADIS-HADIS TENTANG PEREMPUAN SEBAGAI IMAM SHALAT
Authors: Suryadilaga M. Alfatih
Published: October 2017

On the issue of women as imams, traditional Islamic discourses severely limits the chance of women to be leaders of a prayer, even in cases where the women are clearly the most competent, for reasons that are related to gender. A peculiar new view on such discourse is given; basing itself came from the hadith of Ibnu Waraqqah, it stands as a shahih hadith through an analysis of its sanad and matan. This new view expands the chances for women by allowing them to become imams. Though this view is currently considered deviant, its existence must be publicized as a branch of development of fiqh as a whole.
MENAKAR TRADISI KAWIN PAKSA DI MADURA DENGAN BAROMETER HAM
Authors: Sa’dan Masthuriyah
Published: October 2017

There is a tradition of forced marriage (kawin/nikah paksa) in Madurese society in which young  females are paired up with and married off to young males of their parents choosing. Young women may be promised in marriage when they are still in their mothers’ wombs or in childhood, and the marriage age for girls is generally under the age of 18 years, though there are those who marry between 12-15 years. Regeneration of the ancestral lineage can be seen in several areas in Madura including Bangkalan, Sampang, Pamekasan and Sumenep. Instead of the following the prescriptions of Muhammad, girl children have become ‘victims’ of a culture that discriminates  against them. If seen from a human rights perspective, the tradition of kawin paksa breaches the ethics related to humanity, justice and equality.
CONFIRMING DOMESTIC IDENTITY, SUPPORTING PUBLIC COMMITMENT (The Case of Tuan Guru’s Wife in Lombok West Nusa Tenggara Eastern Indonesia)
Authors: Wardatun Atun , Amrullah Asyiq , Musta’in Mr
Published: October 2017

Berbeda dengan Tuan Guru (pemimpin agama) yang merupakan figure penting dan berpengaruh,  bukan hanya agama tetapi juga politik dan budaya, di Lombok, para istri mereka bukanlah tokoh dunia publik. Pengamatan demikian mungkin saja mengindikasikan terjadinya proses domestikasi yang lalu mengakibatkan subordinasi dalam relasi keluarga Tuan Guru. Penelitian ini menawarkan nuansa dan pemahaman lain dalam melihat relasi gender pada keluarga Tuan Guru, dengan menggarisbawahi cairnya demarkasi ruang public dan private yang terjadidi dalamnya. Penelitian ini mengungkap bagaimana sesungguhnya para istri Tuan Guru memposisikan dirinya dalam relasi kuasa pernikahan yang memberikan kesan bahwa relasi gender itu tidak linier dan kaku tetapi kompleks dan cair.  Pembagian ruang public dan private adalah isu penting bagi gerakan feminis.Agama, negara, dan keluarga dikritisasi sebagai lembaga-lembaga yang melanggengkan istrinisasi karena mereka masing-masing adalah dasar bagi, alat untuk, dan tempat bagi suburnya budaya patriarkhi. Ideologi gender yang dianut oleh Indonesia sebagaimana yang termaktub dalam UU perkawinan No 1/1974 misalnya membenarkan dikotomi laki-laki sebagai kepala keluarga dan perempuan adalah iburumah tangga. Negara,melalui system hukumnya, secara aktif memapankan pembagian yang kaku ini sembari menyamarkan berbagai fakta yang terjadi tentang bagaimana sesungguhnya perempuan Indonesia menegosiasikan pembagian yang kaku tersebut. Berdasarkan interview mendalam dengan para istri Tuan Guru dari tiga pondok pesantren yang terbesar di Lombok, penelitian ini mengungkap bahwa pembagian ruang public dan privat dalam keluarga Tuan Guru adalah sebuah cara untuk menegaskan identitas domestic seorang istri dan mendukung komitmen publik para Tuan Guru. Dalam beberapa poin, cara pandang ini memang mengadopsi ideologi yang ditanamkan oleh Negara sebagaimana dikemukakan di atas, tetapi dengan beberapa modifikasi. Garis pemisah antara ruang public dan domestic tidak selalu jelas karena para istripun bertanggungjawab dan terlibat aktif dalam kehidupan pesantren termasuk dalam bidang managemen, pendidikan, keuangan serta aktif berpartisipasi dalam pengembangan dan tanggungjawab social lembaga pesantren. Keterlibatan public istri tuan guru tersebut, hanya saja, bukan atas nama gerakan aktivisme atau pembebasan perempuan, tetapi lebih sebagai mendaulatkan diri mereka sebagai pemain belakang layar yang sangat menentukan keberhasilan perjuangan sosial para Tuan Guru. Di sinilah letak kompleksitas relasi gender itu.

Published: October 2017

Setiap manusia yang hidup di dunia ini semestinya mempunyai hak yang sama untuk mendapatkan  kebutuhan-kebutuhan dasarnya. Namun demikian realitasnya tidak seperti itu. Kelompokkelompok marginal seperti kelompok LGBT akan banyak mendapatkan diskriminasi. Bahkan pendiskriminasian itu sering dilegitimasi sebagai kutukan Tuhan di dunia. Tulisan ini akan mendiskusikan bagaimana Islam dan ummat Islam melihat fenomena homoseksualitas baik dari sisi teologis maupun sosiologisnya. Kelompok yang tidak setuju dengan keberadaan kaum gay ini, berargumen bahwa itu adalah penyimpangan sedangkan kelompok yang peduli melihat bahwa untuk menjadi gay, waria ataupun lesbi bukanlah pilihan dia tetapi itu juga  pemberian dari Tuhan,karena itu tidak adil jika mereka diperlakukan tidak adil dari apa yang terjadi pada mereka yang sebenarnya mereka tidak minta. Perbedaan ini tidak lepas dari pendekatan yang digunakan dalam memahami text-text keagamaan.

Satyra jako wyzwanie dla interpretatora
Authors: Sidoruk Elżbieta
Published: October 2017

The problem of low interest of Polish literary scholars in the satire is discussed in the article. The author points to the need for a deeper reflection on this phenomenon, aimed at restoring the term “satire” as necessary neutral for effective use in the analytical-interpretative practice. Taking into account the autocratic potential of satire, the author suggests to look at it as a form of challenge to the reader, which provokes the search for a “new perspective”.
Gotycyzm/gotycyzmy – rekwizyty i metamorfozy
Authors: Izdebska Agnieszka
Published: October 2017

The article deals with phenomena of the Gothic the most often described as a set of often-linked elements rather than a fixed genre. The text presents a variety of cultural incarnations of the convention: from the eighteenth century novel by horror movies to subcultural style of Goths. This essay also examines the basic Gothic concepts, like the uncanny and the abject, which determine the worlds depicted in Gothic narratives, especially characters who remain in close connection with the space formed as a labyrinth. Finally, the article is an attempt to answer the question about the source of the expansion of the aesthetics of the Gothic in the contemporary culture.
Poetyki i lektury momentalne. Między materią a metafizyką, czyli o paronomazji na przykładzie poezji kobiet
Authors: Grądziel-Wójcik Joanna
Published: October 2017

The paper investigates manners of linguistic description of psychosomatic, autobiographically interpreted experience in contemporary women’s poetry, which is analyzed in the context of the poetics of the moment, with reference to Hans Ulrich Gumbrecht’s concept of “poetry as a mode of attention.” The authoress is particularly interested in the figure of paronomasia, evoking homonymic, parallel spheres: the material and the transcendental one. The article contains close reading interpretations of poems by, among others, Krystyna Miłobędzka, Teresa Ferenc, Bogusława Latawiec and Ludmiła Marjańska, in which paronomasia introduces the reader into a dual dimension of existence, both anchoring the subject in the physical, bodily reality and provoking metaphysical questions.
Wprowadzenie do post-koiné: nieantropocentryczne języki poezji
Authors: Jarzyna Anita
Published: October 2017

The article is a cross-sectional study that analyses contemporary Polish poets’ metapoetic reflections on anthroponormative language and their ways of elaborating alternative ways of representing animals. They often unveil oppressive animalistic metaphors, i.a. writting as hunting, and create less obvious ones, for example the poem as an animal. This kind of image commits both the author and the reader of the poem to care – they are both somehow obligated not to objectify animals in their interpretations. By referring to poems (written by Magdalena Bielska, Stanisław Grochowiak, Ryszard Krynicki, Piotr Matywiecki, Krystyna Miłobędzka, Jacek Podsiadło, Wisława Szymborska, Eugeniusz Tkaczyszyn-Dycki) and inspiring essays by Tadeusz Sławek, the author of this article formulates and leads out a concept of post-koine, which is a language critical towards any too narrow idea of the community (koine), the language of a new interspecies community, an inclusive language devoid of violence against animals.

Authors: Łęczycki Krzysztof
Published: October 2017

Firing from gun armament generates a wide range of physico-chemical phenomena contributing to the degradation of barrel material, e.g. pressure, high temperature, chemically aggressive character of post-detonation gases and friction of a driving band. In this work the technique of thin foils was used in Transmission Electron Microscopy (TEM) to study the influence of physicochemical phenomena on the material microstructure of aircraft gun barrel. A mechanism and reason of premature wear-out of the barrel under consideration was also outlined by utilising light microscopy and hardness measurements.

Economic Assessment of European Beech and Turkey Oak Stands with Close-to-Nature Forest Management
Authors: Csépányi Péter , Csór Attila
Published: October 2017

The paper analyses the complex economic models of continuous cover forestry based on the ‘Dauerwald’ principles in the early transformation period and in the traditional rotation system both in European beech (Fagus sylvaticaL.) and Turkey oak (Quercus cerrisL.) stands in central Hungarian study sites. The analysis was carried out on both the stand and estate-levels, and the performances were compared as well. We found that continuous cover forest management (CCF) can achieve at least the same economic efficiency as traditional rotation forest management (RF) in both beech and in Turkey oak stands. The regeneration problems occurring in poor quality sites in Turkey oak stands made visible the economic differences between the two management systems investigated.
The Effect of Artificial Lights on Nocturnal Macrolepidoptera (Lepidoptera: Macroheterocera) Communities
Authors: Nagy Pintérné Edit , Pödör Zoltán
Published: October 2017

We examined the light sources and illuminated environments in Sopron’s public areas and studied the impact they had on the composition of macrolepidopteran moth communities. We employed light traps with three different light sources in three differently illuminated environments (seminatural, transitional, urban) on 60 occasions during the summer period of 2012-2013 and 20 times in the seminatural area in the spring and autumn of 2014. In the first two years, we evaluated the number of individuals; in year three, we evaluated the number of species. In the first two years, the high-pressure sodium light in the seminatural site trapped the largest number of nocturnal lepidopteran specimens (2,569), while the mixed HMLI light trapped the most individuals in the transitional (1,098) and urban (822) areas. Based on the average number of individuals the first two years, we compared the locations and light sources. In terms of average number of specimens collected, significant differences emerged between two light sources and two locations. When we completed the species diversity index, we determined the compact fluorescent tube in spring and the high-pressure sodium light in the autumn showed the greatest values.
Supporting the Absorbent National Rural Development Planning by Scenarios
Authors: Korompai Attila , Szabó Mátyás , Nováky Erzsébet
Published: October 2017

The practice of Hungarian rural development planning shows the lack of future orientation. The time horizon of planning is short-term, the strategic way of thinking beyond 7–10 years long period is missing or it has great deficiencies. It is not even considering the long-term opportunities. Therefore, the short term plans are not derived from established perspectives, they do not have sufficient grounds. This paper briefly summarises the achievements of a research activity to make an attempt to prove that despite the limitations in understanding and unfolding the future, it is possible to provide useful information for the planning of rural development in 20 – 30 years or even on several more years. This is based on pre-scenarios, highlighting the high efficiency and unexpected weak signals of the driving forces.
Rural Enterprise Hub Supporting Rural Entrepreneurship and Innovation – Case Studies from Hungary
Authors: Katonáné Kovács Judit , Zoltán Erzsébet Szeréna
Published: October 2017

Although the tendency that the population migrate from rural to urban areas is typical world wide, the globalised economy creates new circumstances and opportunities for rural areas as well. The ‘new rural economy’ therefore needs new infrastructure to support it. The authors of the paper have a common interest in how enterprise hubs could help the development of entrepreneurship in the 21st century from two different directions, from physical and from social aspects. Building on the experience gained along enterprise hubs in cities, the hypothesis behind the study is, that creating enterprise hubs from existing buildings in rural settlements could help the development of rural entrepreneurship. To examine the hypothesis two case studies following a period of two years (enterprise hub development in Debrecen and Noszvaj) were carried out. In line with other studies in this field, result shows that even well-designed physical spaces are not enough for change, and initiators, hosts or facilitators are needed, as they play an important role in focusing on the real interaction network and enabling more synergies to happen.
Economic and Social Impacts of Promoting Cultural Heritage Protection by the Czech Rural Development Programme 2007–2013
Authors: Kouřilová Jana , Pělucha Martin
Published: October 2017

Cultural heritage can play a very important role in local and regional development with economic and social effects. The European Union (EU) outlined a specific measure that is aimed at the protection and development of rural heritage within rural development policy in the programming period of 2007–2013. The main aim of this paper is to assess economic and social impacts of projects supported by EU Rural Policy in the Czech Republic during the period of 2007–2013. The implemented projects were located mainly in peripheral rural areas, both near to borders and in inner peripheries, which means that the measure was geographically well targeted. The results of the measure contribute to the restoration and reconstruction of historical monuments, churches, cemeteries and small sacral monuments which create an environment in rural settlements. This environment is very important for the community life and strengthening local identity. In the field of economic development, the results of this measure demonstrate only limited effects in supported villages.
Spatial Planning Experiences for Vulnerability Reduction in the Wildland-Urban Interface in Mediterranean European Countries
Authors: Galiana-Martín Luis
Published: October 2017

Expansion of the wildland-urban interface in countries in the European Mediterranean basin is increasing vulnerability to forest fires. Despite more effective extinction systems, this is still a growing problem. This article defends the importance of spatial planning (land-use and urban planning) and the need for systematic intervention to mitigate this wildfire risk. A critical review of the current situation, noting intervention focused on buildings and plots and insufficient action on intermediate spatial scales, is followed by the presentation of significant and relevant experiences in the European context.

The paper analyses biometrical and anatomical traits of wood in a leaning stem of pine trees. For study purpose, five pine trees (Pinus sylvestris L.) with a visibly leaning stem were chosen. Wood samples were taken at three different stem heights, that is, below the stem curvature, at the curvature and above the curvature. Microscopic specimens were prepared and used for the following measurements: annual rings width, tracheids diameter and tracheids wall thickness. The measurements were performed for wood located on the lower side of the leaning stem and on the opposite side. Cytochemical staining was performed to identify the occurrence of laricinan. The results showed tracheids with a rounded shape and thick cell walls, helical cavities and intercellular spaces in wood located at curvature height on the lower side of the leaning stem. These traits indicate a severe compression wood that allowed pine trees to change their stem position in relation to the vector of gravity.

In forestry, alien tree species are planted to maximize yield from a stand by increasing productivity and decreasing environmental risks. In Eastern Europe, lodgepole pine (Pinus contortavar.latifolia) might be used as a source of biomass and industrial wood; however, before any recommendations are given, possible gains of the novel species should be scrupulously evaluated. In this study, we compared volume and proportion of knotty stemwood (VKN) of native Scots pine (Pinus sylvestris) from first generation seed orchards and provenances of alien lodgepole pine [Fort Nelson (58°38’ N, 122°41’ W) and Summit Lake (54°24› N, 122°37› W)] at the age of 27 years growing in central Latvia. We also assessed the relationships between VKN and several morphometric parameters.

Stem diameter of both species was similar; however, Summit Lake provenance of lodgepole pine exceeded Scots pine in height, while Fort Nelson provenance was lower than Scots pine. Although Scots pine produced nearly two times less whorls than lodgepole pine, volume of knotless stemwood did not differ significantly between the species; though it was higher for Summit Lake provenance of lodgepole pine compared to Scots pine. In contrast, the proportion of VKN differed significantly between both the species and the provenances. Scots pine showed the lowest proportion of VKN (~ 9%) and Fort Nelson provenances of lodgepole pine showed the highest proportion of VKN (~ 14%). Thus, Summit Lake appears more suitable for the production of industrial wood amongst the provenances of lodgepole pine; nevertheless, higher quantity of leftover material is expected. Some morphometric parameters correlated with VKN and the proportion of VKN, but these relationships differed between species and provenances. The total cross-section of branches was the best predictors of VKN for Scots pine and Fort Nelson provenance of lodgepole pine, while stem diameter showed the strongest correlation for Summit Lake provenance. Number of whorls and mean diameter of living branches were the best predictors of the proportion of VKN for lodgepole pine and Scots pine, respectively. Accordingly, morphometric parameters might be useful for the selection of the best trees of lodgepole pine.

The hosts of Hantavirus are rodents, while they are transmitted to humans via aerosol, or by direct contact with them. The primary goal of the study was evaluation of the state of health of forestry workers by laboratory diagnosis of the diseases caused by Hantavirus Dobrava/Hantaan. The study covered a group of 820 randomly selected employees of the State Forests from 32 Forest Districts located in the area of the whole of Poland. The results of the study show that the largest number of positive results were registered in the Augustów Forest District – 3 cases (10%), and in Piotrków Trybunalski – 3 cases (11.5%). For the whole of Poland, 25 seropositive results were noted (3%) and 76 results were doubtful (9.3%). The results of the conducted study suggest the occurrence of Hantavirus Dobrava in large forest complexes on the territory of Poland. People residing and working in these areas are exposed to infection, and this exposure seems to be comparable with data from other countries.

This research presents the variability in the survival and growth for 27 provenances of spruce (Picea abies (L.) Karst. and Picea obovata (Ledeb.)). All the tests were carried out in Russia, Arkhangelsk region, 62º 54’ N, 40º 24’ E, in the northernmost site of the State Geographic Network, established in 1977.

For the research on the spruce provenances, standard methods for studying the geographic variation of the main forest-forming species were used. Growth rates of provenances were correlated with their geographical coordinates and climatic characteristics. Data was expressed in standard deviation units to select the best in growth provenances.

Despite the significant differences in the location of the original stands (up to 12º N and 37º E), variability in survival, height and diameter is low (coefficient of variation is 12.2–19. 0%). Obtained data indicated that provenances’ growth is correlated on longitude of the location rather than on the latitude. Diameter and average height of provenances significantly depend on annual rainfall.

The height of provenance is mostly dependent on the location of the initial habitats and their climatic characteristics. It is also related to the length of the growing season and the air temperature (annual average and in January).

Groups of the provenances of the best and the worst growth were distinguished. The group of the best ones on the integral indicator (volume stand) includes provenances of the western origin represented by P. abies and its immediate hybrids – Karelia (3), Vologda (24), Leningrad (5), Pskov (7) and Moscow (29) Regions – and provenances of the eastern one represented by P. obovata – Komi (26) and Perm (38) Region. High plasticity of spruce (P. abies (L.) Karst. × P. obovata (Ledeb.)), growing within the Russian Plain, in sufficiently favourable conditions of middle taiga subzone (Arkhangelsk Region, Russia) was proved.
The Characteristics and the Concept of the Utilisation of Post-Production Calcareous Waste Deposited in Landfills

Published: October 2017

This article presents the results of research into calcareous waste from the production process of oxide propylene. The obtained results show a considerable chemical diversity of calcareous waste with a predominant percentage share of Ca, C and Cl, which are the products of the process. It was shown that the share of calcium bonded in CaCO3was over 20%, which is indicative of the secondary carbonisation process taking place in the waste. The morphological and structural analyses revealed that the grains had a surface area above 12% and a percentage porosity in the range of 25-35%. The reactivity test made it possible to classify calcareous waste as a material for sorbents of 'satisfactory' sorption properties, insufficient to be effectively used in the power sector. For the stored waste to be reused, it is necessary to improve its sorption abilities through the application of a properly selected activation method.
Development of an Innovative Approach for Complex, Causally Determined Failure Chains

A high number of examples in today’s global industry prove that it is difficult to ensure a certain level of quality. One possible reason is the increasing complexity of modern mechatronic product systems. Interface problems due to several involved science disciplines and the lack of understanding subsystems, which are delivered by different suppliers, make it difficult to identify critical components and specifications of elements. Furthermore, it is even harder to estimate the effects of elements because of their unknown dependencies and relations. Therefore it becomes more and more improbable to develop a safe, sustainable and high quality product right from the beginning.

In order to understand failures in complex system structures today’s engineering industries need a generic approach that increases the understanding of systems, identifies critical components and considers the different levels of a system. It shall examine failures that cause system errors but also failures that limit system functions. Thus, it is necessary to model and simulate the causally failure chains and analyse over several system levels and elements with their dependencies. This leads to a better understanding of the whole picture of cause and effect.

This research paper points out which requirements this new model-based approach has to fulfill and how it is possible to link quality and reliability methods to achieve an overall understanding and analysis of a complex system to assure high quality and sustainability.
