The impact of Fenton's reagent was investigated on changes in sorption capacity of the active WD-extra carbon applied to dye removal from the textile effluent. The wastewater contained three dyes, i.e. Bemacid Red NT-F, Bemacid Yellow NT-F and Bemaplex Black D-R. Adsorption jar tests demonstrated dye removal at the level of 52-62% for fresh carbon and reduced sorption capacity of carbon regenerated with Fenton's reagent. It was established that dye removal efficacy of the five-fold reactivated material was at the level of 23-49%. Reduced sorption capacity resulted from the changes in surface structure and chemistry of the active carbon. Following successive regenerations, the active carbon was characterized by lower specific surface area, higher concentration of surface acidic groups and lower basic groups content. Loss in weight was an unfavorable phenomenon accompanying carbon reactivation that limited its fold.


The paper is a review of the literature, including the authors'own studies, concerning the thermal stability, flammability and mechanical properties of elastomeric nanocomposites containing montmorillonite clay or halloysite nanotubes. The thermal decomposition of elastomeric nanocomposites was investigated, taking into account the type and quantity of the nanoadditive, its barrier properties, the structure of carbon layer as well as the interactions between the nano-additive and reactive groups in the elastomer.


The paper is a continuation of literature review on thermal stability, flammability and mechanical properties of elastomeric nanocomposites containing montmorillonite clay, halloysite nanotubes, attapulgite as well as carbon nanotubes and nanofibres. The mechanism of degradation and thermal decomposition of elastomeric nanocomposites was examined from the point of view of: the type and amount of nanoaddititve, structure formed during the combustion of carbon layer, barrier properties of the nanoparticles as well as the interactions between a specific additive and reactive groups in the elastomer.


Cephalanthera damasonium (Mill.) Druce is rare and protected species. It is also placed in the "red list" of vascular plants threatened in Poland (V category) and of the Małopolska Upland (VU category). The new locality of C. damasonium was found in 2014 on remnants of former iron-ore mining in the Suchedniów Forest Inspectorate (Małopolska Upland, ATPOL grid square EE5502) (Fig. 1). A population of the species counted 30 individuals (10 specimens in generative and 20 in vegetative state) which grew in phytocoenosis of the Querco-Fagetea class. To protect the new locality of C. damasonium and also an old extraction site (which is interesting from environmental viewpoint) - the part of forest compartment with fertile beech forest community should be excluded from forest management.

Eating disorders pose a serious medical, clinical and social problem. In the recent years cases of the lack of appetite are more often diagnosed in reference to middle-aged and elderly women. A situation like this may result from an existing disease process, a continuation of experiencing such problems in the past, and also a reflection of the trends being created by the modern media advocating the need for keeping a woman's physical attractiveness in her late adulthood. It happens more and more often that the effort to reduce weight achieve a slimmer look is taken by women in their 50s, and even 60s. There is also an existing view that eating disorders among elderly women appear in a close connection to psychical disorders. Many women perceive menopause as a loss and a sign of an oncoming old age, thus they are focused mainly on negative emotions in this period of life. On the basis of depression-like disorders, there appear problems with controlling and maintaining the body mass. Although the scale of the phenomenon has still a limited range and character, its significant impact on life quality of women's population in the menopausal period justifies the execution of the current review of the subject literature in this matter.


This paper is the first part of cycle of articles concerning information about protected, threatened and rare vascular plants species growing in forest communities which emerging on old iron-ore extraction sites situated in the northern outskirts of the ͆więtokrzyskie Mountains (the Małopolska Upland). The paper gives localities of 41 taxa recorded in years 2010-2013:12 mountain species, 15 protected species and 19 threatened species. The last taxa are the rare plants in the region. All of the taxa represent native element in the Polish flora.


This paper contains information about protected and threatened vascular plant species of the Garb Gielniowski Hummock. In flora of the mesoregion there are: 80 protected species (including 65 strictly protected species and 15 partially protected species) and 158 threatened species (therein 154 species are placed on the red list of the Wyżyna Małopolska Upland and 39 species are threatened in Poland). Original local red list of vascular plant species of the Garb Gielniowski Hummock contains 133 species in seven individual threat categories: 18 species extinct in the mesoregion (RE category); 25 critically endangered species (CR category); 19 endangered species (EN category); 44 vulnerable species (VU category); 15 near threatened species (NT category); 10 least concern species (LC category); 2 data deficient species (DD category). Share of these species in habitat groups shows domination of forest and shrubs species (46 species). Quite numerous are also peat-bog species (18 species), meadow species (17 species) and species occur on waterside and muddy sites (14 species) - these habitat groups are the most typical for all native flora of mesoregion.

Sannikov Land was one of the greatest myths of Arctic geography, probably seen for the first time in the 17th century and remaining fascinating to this day. Convinctions as to the existence of this area resulted in the organisation of various expeditions of discovery. Among these efforts, the one mounted on the greatest scale with a view to Sannikov Land finally being discovered was the 1901-1902 expedition of Eduard Toll.This ended tragically for the explorer himself, while leaving the question of the existence of Sannikow Land unresolved. An answer (in the negative) finally came with systematic cartographic study carried out in Soviet Russia. However, the non-existence ofSannikov Land from the point of view of geography has not prevented it from winning a permanent position for itself in pop culture, through its inspiration of books, films and computer games. © 2014, Polska Akademia Nauk.

This paper is the fourth part of the cycle of articles based on the floristic studies carried out in the Garb Gielniowski Hummock (Wyżyna Małopolska Upland) in years 2002-2007 - it contains information about 24 ecological plants types which have been distinguished on the basis of scale degrees used in ecological indicator values. Seven soil values and also light value have been taken into consideration. Analyses of occurrence of plants with narrow tolerance scale show dominance: acidophilous species (189) over alkaline species (167), species of soils poor in nitrogen (266) over nitrophytes (244), hygrophytes (285) over xerophytes (175) and species growing on organogenic soils (151) over species which occur on soils poor in humus (53). Plants types attached to moderate habitat conditions (in case of every analized ecological value) comprise paramount percent of flora of mesoregion and its frequency in individual cartogramme units coincides with total number of species which have been ascertained in every ATPOL square. Additionally, quantitative cartogramme maps which show share and distribution of species of ecological plants types in individual square units are also included.

Abstract This paper is the second pARt of the cycle of ARticles based on the floristic studies cARried out in the GARb Gielniowski Hummock (Wyzyna Małopolska Upland) in yeARs 2002-2007 - it contains information about anthropophytes. Flora of alien plants of study ARea consists 220 species - 180 meta-phytes (87 ARchaeophytes and 93 kenophytes) and 40 diaphytes (3 ephemerophytes and 37 ergasio-phygophytes). Both in group of ARchaeophytes and kenophytes prevail species which occur very rARe in cARtogramme units of investigated mesoregion. Almost half of all kenophytes of flora of the GARb Gielniowski Hummock ARe species from list of the most frequent kenophytes in Poland. Additionally, the ARticle contains chARacteristic of synanthropic flora on the ground of numeral index.
