To be an art conservator, one needs to have the skills of an accomplished painter, the knowledge of an art historian, the enthusiasm of a chemist, and the nose of a detective – says Marta Zaborowska from the Faculty of Conservation and Restoration of Works of Art at the Academy of Fine Arts in Warsaw.

The article presents the architectural heritage created as a part of the Central Industrial District in the context of the need for its preservation and protection. Presented are selected topics and problems associated with the current technical condition of both industrial and residential buildings. The analysis contain also the impact of modern conservation doctrines and their ability to preserve works of COP’s architecture with the specific conditions of ownership, poor awareness of users and owners, and a large shortage of historical planning sources.

Conservation of the Old Town Zamość began to realize almost a hundred years ago. Then the eminent preachers of culture in the early period. 20.year inter-made idea of restoring the prestige of the works of Polish culture. The idea of protecting national cultural heritage grew gradually until such time as the first scientific research, development of standards and principles of care and maintenance. Today Zamość was inscribed on the UNESCO World Cultural Heritage. Many things made, much remains to be done.

This paper present the data for monitoring forest conditions and forest resource management by a local community adjacent to the Doi Laung Wildlife Sanctuary, Huaimai Sub-district, Song District, Phrae Province, Thailand. This study uses quantitative forest surveys, interviews, discussions, and descriptions of the historical context of public participation in forest management including a detailed assessment of field conditions. The findings of a forest resources inventory show that (1) from the three sampled areas, Doi Laung Wildlife Sanctuary has highest richness, followed by village #16 and #14, and (2) Huaikhon #16 implied the process of framework to maintain a healthy condition and response to community needs with collective management. The conceptual model assessment that links key group indicators and drivers is presented based on previously developed assessment models. The framework focuses on the best way to provide forest management, forest fire prevention, and firefighting as well as monitoring of Check-dam construction and other activities that support the recovery of the forest community. This paper demonstrates the general of an environmental assessment framework to applying organize environmental information to facilitate policy decision making for the sustainable development.

The majority of publications and monographs present investigations which concern exclusively twophase flows and particulary dispersed flows. However, in the chemical and petrochemical industries as well as in refineries or bioengineering, besides the apparatuses of two-phase flows there is an extremely broad region of three-phase systems, where the third phase constitutes the catalyst in form of solid particles (Duduković et al., 2002; Martinez et al., 1999) in either fixed bed or slurry reactors. Therefore, the goal of this study is to develop macroscopic, averaged balances of mass, momentum and energy for systems with three-phase flow. Local instantaneous conservation equations are derived, which constitute the basis of the method applied, and are averaged by means of Euler’s volumetric averaging procedure. In order to obtain the final balance equations which define the averaged variables of the system, the weighted averaging connected with Reynolds decomposition is used. The derived conservation equations of the trickle-bed reactor (mass, momentum and energy balance) and especially the interphase effects appearing in these equations are discussed in detail.

The paper presents the results of field studies carried out in I O chosen forest islands in a suburban area of the town of Jaworzno in the years 1995-2002. Different objects have been studied, among others: natural remnants of oak-hornbeam forest and planted pine-larch woodlots cultivated on the habitat of xerothermic grasslands. In comparison with the total nora of the town, the participation of non-synantropie species and synecological groups associated with natural habitats is much bigger. There are 24 protected species to be found, 40% of protected nora of the town. Despite their diversity, they are precious refugees of many woodland and grassland as well as meadow species occurring within the areas and in their vicinity.

The interiors of the Imperial Castle in Poznań are embellished with scores of different stone varieties. In order to preserve and renovate them, an in-depth conservation examination needed to be performed.

Genetic diversity manipulates a prime and vital role in the sustainable use of genetic resources. The data highlighted more insights into the genetic diversity of the arta plant ( Calligonum polygonoides subsp. comosum) populations collected from three localities, Qalabshu ( QQ), Mutubas ( MM) and Gamasa (GG), in Egypt as gene pool for biodiversity conservation and afforestation. Random amplified polymorphic DNA (RAPD) markers investigated the population pattern and structure. A total of 129-amplicons oscillated from 145 to 1505 bp and a total of 19-amplicons were specific markers with an average of nine bands for each population. The Shannon index (I) scored at an average of 0.3. The diversity ( h) oscillated from 0.11 to 0.25. The similarity matrices based on Jaccard coefficient recorded positive values. A higher correlation (r = 0.83) was between the combined Qalabshu (QQ) and Mutubas (MM) matrices using the Mantel test with 1,000 permutations. This species has higher adaptability for their regions. This gene pool is a valuable reservoir for enriching genetic diversity and provides basal information for the biodiversity conservation of a dominant species. The dominant species can be utilised in afforestation in the same region or another region which has the same environmental conditions.

Selected Legal Regulations and Cultural Aspects of Urban Development. Nowadays, the issue of urban development belongs to key elements of development in general. Urban development is a multifaceted phenomenon (covering economic, social, administrative, promotional, ecological and a number of other aspects). They are too numerous to discuss them in one short article. For this reason this paper is dedicated only to the phenomena regulated by law: physical planning, suburbanization (initially called urban sprawl), monument conservation and – additionally – culture (as a factor influencing the legal regulations). The key hypothesis is that developers are not the only ones to blame for the way the country looks. This hypothesis has generally been corroborated.

An efficient micropropagation system for Taraxacum pieninicum using seedling explants germinated in vitro is described. Shoot tips and fragments of cotyledons, hypocotyls and roots were isolated from several-day-old seedlings. The highest response, 100% frequency with 12.3 axillary shoots/explant, was from shoot tips on medium supplemented with 0.5 mg L-1 BA and 0.05 mg L-1 NAA. In subsequent subcultures the number of shoots was significantly higher on all explants cultured on medium containing 0.25 and 0.5 mg L-1 BA, and the multiplication rate was highest (20 shoots/explant) in the 4th passage. Shoots rooted on MS and 1/2 MS medium; the highest rooting frequency was 90% and the highest number of roots 2.7/shoot. Rooted plants showed 96.2% survival in sterile soil:sand, and 100% survival in hydroponic culture. Regenerated plants flowered in the second year after acclimatization and yielded viable seeds. This protocol for obtaining complete plants through micropropagation may prove useful for conservation of the genetic resources of this and other endangered species

An interesting fact in the intellectual history of the fin-de-siècle and first three decades of the 20th century is that the crisis of modernity was understood in categories of sex and gender. In spite of the differences dividing the German intellectual trend of cultural pessimism, the conservative revolution, and Fascist thinking, all these paradigms are linked by the characteristic conviction that ‘modernity’, being the consequence of the French Revolution, was ruled by the ‘feminine principle’. This principle was supposed to represent what is anti-military, anti-state, and anti-cultural at the same time. Variations on the theory of male bonding (Männerbund) were the intellectual reaction to that ‘feminine principle’. The intellectual patterns described here find their continuation in contemporary conservative thought.

This paper presents a new concept of disinfection traditionally applied in water treatment systems. The new definition of this process results from the change in its functionality, aims and methods, which guarantee high quality of water supply. The literature review and technical practice demonstrate a demand for disinfection to act as a functional element of the integrated water distribution system and an active intermediate link between the technology of water treatment and the water distribution network. The presented concept of a disinfection process enables evaluation of water treatment, increases its effectiveness in integrated water treatment systems. Such defined disinfection addresses water conservation and its biological stability within the water supply network. The presented here new concept of disinfection assigns its new role and function in the integrated water distribution system. The controlling and diagnostic function of the disinfection defined in the paper provides a transparent and comprehensive method, with considerable application in experimental design, as well as practical solutions for integrated water distribution systems.

Rare and endemic plant species represent important components of plant biodiversity which require protection to ensure their sustainable conservation. Cerastium banaticum (Rochel) Heuff. is such an endemic and rare species from Romania, for which the genetic variability of two natural populations was studied by SSR markers. Shannon’s information index revealed low levels of genetic diversity in both populations (I = 0.296). As the first attempt in a conservation program a reproducible micropropagation protocol was established starting from seeds, followed by multiplication, rooting, and ex vitro acclimatization. Among the various plant growth regulators tested the highest multiplication coefficient was achieved on a culture medium with 0.5 mg L-1 6-furfurylaminopurine (K) and 1 mg L-1 α-naphthaleneacetic acid (NAA). On this PGRs concentration a number of 26.6 shoots/individual explant with a mean length of 7.9 cm for new generated shoots was registered. The highest number of roots/individual initiated shoot was 2.6 and it was recorded on a culture medium with 0.5 mg L-1 2-isopentyl-adenine (2iP) and 0.1 mg L-1 NAA. The outdoor acclimatization was successfully performed in a specially designed rocky area in the ‘Alexandru Borza’ Botanical Garden, Cluj-Napoca (Romania).

The article presents and describes the methodology of the conservation of stone structures that are architectural monuments discovered as part of the work carried out during archaeological excavations in Tanais. The authors’ experiences presented in the article result from many years of cooperation between the Faculty of Civil Engineering at Warsaw University of Technology and the Antiquity of Southeastern Europe Research Centre at the University ofWarsaw. Examples of preserved masonry structures come from an excavation in Tanais near Rostov-on-Don. Works on stone structures located in the area of archaeological excavation are characterised by a unique specificity covering both formal issues, resulting from international standards and agreements regulating the conservation of historic buildings, as well as technical and environmental issues. The primary technical issues include ensuring the safety of further excavation works, protection of masonry structures against the destructive effects of atmospheric conditions and preparing the structure for possible exhibition in archaeological parks organized on the site of excavations. The article presents the procedures that should be used to conserve this type of structure and the specific sustainable technological and material solutions used in the shown objects.

Habitat fragmentation is one of serious threats to biodiversity of nature in today's world. The present study of a typical steppe species Iris pumila L. (Iridaceae) has analyzed the impacts of geographical isolation and population size on genetic diversity and population structure in conditions of habitat fragmentation. The key indices of population genetic variability calculated from the ISSR markers data were on average as follows: Shannon diversity index (S) – 0.188; unbiased Nei’s gene diversity (He) – 0.123; and the average measure of Jaccard’s genetic distances between individuals within populations – 58.4%. Although the largest population had significantly higher values of S and He, the small and marginal populations also showed a comparable level of variation. Most of the genetic variation of I. pumila was distributed within the populations. A strong correlation was found between Nei’s genetic distances and geographic distances between the populations. According to the Bayesian analysis, genetic structure of the populations was highly homogeneous; however, the presence of admixed genotypes indicated the possibility of gene flow between the populations at present.

The genus Narcissus has several endemic, rare and/or threatened species in the Iberian Peninsula and North Africa. In vitro propagation is a useful tool for threatened plants conservation used in ex situ strategies. Thus, the aim of this work was to study the propagation in vitro of bulb scale explants of five endemic, rare and/or endangered Narcissus species from the Iberian Peninsula, treated with different PGR combinations. Initiation was achieved in half-strength Murashige and Skoog (MS) basal salts and vitamins, 10 g/L sucrose, 500 mg/L casein hydrolysate, 2 mg/L adenine, 10 mg/L glutathione and 5.5 g/L plant agar. In the multiplication phase, the highest bulblet proliferation was obtained in MS medium supplemented with 30 g/L sucrose and the combination of 10 μM 6-Benzylaminopurine (BAP) + 5 μM α-Naphthaleneacetic acid (NAA) in N. alcaracensis, N. eugeniae and N. hedraeanthus; 20 μM BAP + 5 μM NAA in N. jonquilla and N. yepesii. The highest rooting was obtained with 5 μM NAA + 1 μM Indole-3-butyric acid (IBA) for all species (>75%) and more than 80% of the produced bulblets were successfully acclimatized.

Tension-strut systems consist of thin cables and membranes capable of carrying only tensile forces and compressed struts cooperating with them. They make very effective use of strength properties of materials. They are lightweight and common in large span structures such as bridges and stadium roofs. However, they may also be advantageous in reinforcing and repairing historical buildings as they conform to conservation law in force. This paper presents a few examples of such applications of tension-strut system. Stabilization of historic brick and stone vaults with buttresses and iron bowstrings often turns out inadequate to resist thrust forces transmitted from the vault to the walls which cause cracks and deformations of the vault. Properly designed tension-strut structure can resist the thrust forces calculated in a theoretical way. Moreover, it can be hidden in the attic of building. Old timber roof structures are usually deformed and excessively deflected. Skilfully assembled tensionstrut systems enable straightening and geometrical adjustment of a roof structure. Although similar threats and structural damages occur in most buildings which are a few hundred years old, individual design solutions are required in each case. Historical investigation and detailed measurement of geometry and deflections have to be made before choosing the apprioprate method of reinforcing the old structure.

This paper presents two photographs referred to as pannotypes (from the Latin word pannus) from an album of photographs. It discusses the history of the pannotype technique, which was popular in the 1850s and 1860s in photography ateliers all over the world (it presents a review of materials and substances used in this technique and the transferring of the negative layer onto a black, flexible substrate). Pannotype is one of the most interesting techniques used in the 19th century. The paper then discusses the Kórnik photographs, the people they show, and their dimensions and structural features. Some conservation-related remarks on the susceptibility of precious objects of this type to damage also follow.

This paper is intended as a contribution to broader considerations and discussions on the still overlooked issues of garrison landscape architecture, its canon – the essence of the place, its identity. Thus far, the issues of garrison space, its attributes – architecture, elements of development and organised greenery – have been beyond the mainstream of scientific deliberations and constituted a peculiar taboo for various reasons and due to specific transition points in history. Being both closed areas and, after the end of their military functions, post-military ones, they are particularly suitable for playing a significant role in urban relations of inner-city areas and their contemporary conservation creations. In the referenced designs and executions, they can provide examples of development directions that take into account their previous military identity – the spirit of the place.

This study aims to evaluate the construction mode of small-scale farmland water conservancy using secondary data from the China statistical yearbook (2000–2019), which was simply and statistically computed. To put it briefly, the simple linear regression model was used to analyse the number of small-scale reservoirs and irrigated areas relative to their capacities and effectiveness. The results showed that the number of small-scale reservoirs increased by 122.2 units of their capacity and the number of small-scale irrigated areas increased by 6.8 units of their effectiveness. The present study introduces the simple linear regression model and accounts for how the number of the small-scale reservoirs and irrigated areas has increased (the total number of reservoirs was 83,260 in 2000 and 98,822 in 2018) relative to their capacity and effectiveness, respectively. Of course, the capacity of water harvesting and the effectiveness of irrigated areas have shown a linear increase over time. Between 2000 and 2019, the capacity increased from 3842 to 7117 for large-scale reservoirs, from 746 to 126 for medium-scale reservoirs, and from 594 to 710 for small-scale reservoirs and their ranges were 3.2, 380, and 116, respectively. Furthermore, the findings of this evaluation provide insights for making decisions on water conservancy interventions.
