Abstract

The ecological environment is significantly vulnerable to coal-mining activities in western China due to the cold and arid climate. The evaluation of land reclamation is therefore a key process that has to be known for the sustainable use of coal resources. A Bayes discriminant analysis method to evaluate the suitability level of land reclamation for coal mine lands in cold and arid regions of western China is presented. Ten factors influencing the suitability of land reclamation were selected as discriminant indexes in the suitability analysis. The data of eighty-four land reclamation units from sixteen coal-mining areas was used as training samples to develop a discriminant analysis model to evaluate the suitability level of land reclamation. The results show that the discriminant analysis model has high precision and the misdiscriminant ratio is 0.02 in the resubstitution process.The suitability levels of land reclamation for eleven sites in two coal mine lands were evaluated by using the model and the evaluation results are identical with that of the practical situation. Our method and findings are significant for decision makers in similar regions who want to prepare for possible strategies for land reclamation in the future.

Abstract

This paper tackles the questions of material culture and protecting heritage values through urban intervention. Urban intervention is understood as the identification of local heritage with a diagnosis of potential development profiles and application of the adopted solutions to underlie the formation of a new local centrality. It is underlined that the right urban intervention needs to be conducted for and with local inhabitants. Urban intervention, as proposed in this paper, is understood as a tool to properly direct the development of peripheral areas, especially rural ones. The basis for the research is the idea of spatial re-definition that aims to upgrade not only spatial but above all social attractiveness. An original two-stage methodology adopted for the purpose of the research with the use of the author’s AIA method was presented. This developed tool can harness the potential of material culture of local heritage. The shown research methodology is universal and can be applied in any urban interventions intended to transform places characterized by either partially or completely lost spatial and social identity.

Abstract

The paper focuses on the static behavior of double-layered tensegrity grids. Due to the specific characteristics, like the self-stress states and infinitesimal mechanisms, tensegrities can be used as deployable structures. For such structures, the possibility of the control of the behavior is very important. The main purpose of the work is to prove that the control of tensegrity structures with mechanisms is possible. The stiffness of such structures is found to depend not only on the geometry and material properties, but also on the initial prestress level and external load. In the case, when mechanisms do not exist, structures are insensitive to the initial prestress. It is possible to control the occurrence of mechanisms by changing the support conditions of the structure. Grids built with modified Simplex modules are considered. Two-stage analysis is performed. Firstly, the presence of the characteristic tensegrity features is examined and then, on that basis, the structures are classified into one of two classes. Next, the influence of the level of initial prestress on the behavior of structures under static load is analyzed. To evaluate this behavior, a geometrically non-linear model is used.

Abstract

The article features an analysis of the ideas of Yurij Levada, an eminent Russian academic, sociologist dealing both with theory and with practice of sociology, a founder of a research institution inMoscow known as Levada-Centre. Levada gave a special place to culture within sociology and he himself called his project on theoretical sociology an “attempt at culturally justified sociology” (grounded in a perspective orientated to culture). The project was based on structurally complex, culturally conditioned and symbolically indirect social actions. In his opinion, such knowledge of culture required to be looked at retrospectively, which provides for tackling the issue of social system reproduction while enabling to understand contemporary culture at the same time. This way of thinking was a basis for Levada’s analyses of the surrounding social reality, e.g. his analyses of intelligence or the concept of “simple Soviet man”.

Abstract

The article explores the influences and reinterpretations of Roman Ingarden’s philosophy that can be found in Leopold Blaustein’s work. The latter studied in Lvov under Ingarden and established a long‑life philosophical dialogue with his mentor. There is a common agreement in comparative literature on the two authors which claims that Blaustein was influenced by Ingarden mainly in the field of aesthetics. This author supports a different proposition that these influences were much wider and encompassed methodology and theory of consciousness as well. The article is divided into three main parts. First, Blaustein’s critique of eidetic methods in phenomenology is reconstructed. In this context, it is claimed that Blaustein’s arguments aim at Ingarden’s concept of phenomenology rather than at Husserl’s. Yet, even if Blaustein tended to understand phenomenology as descriptive psychology, and Ingarden – as eidetic analysis, they both seemed to agree that phenomenology consisted in rigorous description of the ways of how the objects are given in experience. Secondly, Blaustein’s argument against Husserl’s theory of consciousness is reconstructed. The author claims that the argument is based on Ingarden’s differentiation between ‘living through’ and ‘experiencing’ sense data. Finally, the author examines some points that connect or divide both aesthetical theories.

Abstract

O b j e c t i v e: The main goal of our studies was to investigate the eff ect exerted by pulsed electromagnetic filed (PEMF) on adipocytokines secretion in cell culture supernatants from rat adipose derived stem cells (ADSCs) grown on varied energy-rich diet. Off spring and adult animals were randomly selected for two types of experimental diets: low (LF) or high fat (HF) diet for 7 weeks. After the diet period, serum glucose level was measured, ADSCs were isolated from adipose tissues from different locations. ADSCs from all experimental groups were exposed to PEMF, supernatants collected and adipokines level was determined.

R e s u l t s: HF diet feed in pups/adult animals elevated blood glucose level and increased the level of adiponectin (Apn) and leptin of both genders and age measured in serum. ADSCs cell cultures originated from female pups on LF diet and exposed to PEMF released large amounts of Apn. PEMF effect exerted on Apn release was also observed in ADSCs isolated from male pups HF diet. ADSCs from female pups on LF diet exposed to PEMF released smaller amounts of leptin in comparison to cell cultures without PEMF treatment. PEMF exposure of ADSCs cell cultures originated from female adults on LF diet decreased release of Apn, contrary adult male on LF diet ADSCs under PEMF treatment produced more leptin. PEMF treated male HF diet-originated ADSCs cultures released significantly more leptin than controls.

C o n c l u s i o n: Our results suggest that PEMF exposure is responsible for metabolic physiological balance effects obtained in ADSCs cultures originating from adult animals on HF diet.

Abstract

Missing traffic data is an important issue for road administration. Although numerous ways can be found to impute them in foreign literature (inter alia, the most effective method, that is Box-Jenkins models), in Poland, still only proven and simplified methods are applied. The article presents the analyses including an assessment of the completeness of the existing traffic data and works related to the construction of SARIMA model. The study was conducted on the basis of hourly traffic volumes, derived from the continuous traffic counts stations located in the national road network in Poland (Golden River stations) from the years 2005 – 2010. As a result, the proposed model was used to impute the missing data in the form of SARIMA (1.1,1)(0,1,1)₁₆₈. The newly developed model can be used effectively to fill in the missing required days of measurement for estimating AADT by AASHTO method. In other cases, due to its accuracy and laboriousness of the process, it is not recommended.

Abstract

The article presents a selection of 15th century printed matters on the topic of broadly understood medicine, which are currently kept by the Gdansk PAS Library. They testify to the Gdansk culture in the area of the knowledge on health and hygiene in the 15th century and in a slightly later period. The majority of the said printed matters originate from the collections of Gdansk church libraries, while the presence of items of other origin (private owners) makes it possible to trace the road medical incunabula came to Gdansk to finally find their way to the resources of the Gdansk library.
The author of the article explains the modesty of the Gdansk medical literature resources with the fact that there was not a single university functioning in the city by the River Motlawa in the early modern period. The presence of this kind of incunabula in church libraries and private collections of books indicates that the knowledge they contained was applied for personal use rather than in professional medical practice, although some of the items in question originate from book collections belonging to doctors.
