Abstract:

Objective: The present study was undertaken to investigate the effect of biochemical sources viz., growth regulators and trace elements on the vegetative growth of Pleurotus sapidus Quél. It has a great commercial potential being an edible and wood decaying fungus. Mushrooms need carbon and nitrogen for structural and functional purposes in addition to trace elements, growth regulators and vitamins. Therefore, evaluation of their role in influencing the growth of the mushroom is a necessary aspect to be studied.Methods: Fresh sporocarps of P. sapidus were collected from rotten stumps of Grevil

Abstract. The incorporation of heavy metals into carbonate tests of the shallow water benthic foraminifer Ammonia tepida was investigated under controlled laboratory conditions. Temperature, salinity, and pH of the culture solutions were kept constant throughout the duration of this experiment, while trace metal concentrations were varied. Concentrations of Ni, Cu, and Mn were set 5-, 10-, and 20 times higher than levels found in natural North Sea water; for reference, a control experiment with pure filtered natural North Sea water was also analysed. The concentrations of Cu and Ni from newly

Abstract:

Iron is one of the trace elements required by human body, and its deficiency can lead to abnormal bone metabolism. In this study, the effect of iron ions on the properties of tricalcium silicate bone cement (Fe/C3Ss) was investigated. It effectively solved the problems of high pH value and low biological activity of calcium silicate bone cement. The mechanical properties, in vitro mineralization ability and biocompatibility of the materials were systematically characterized. The results indicate that tricalcium silicate bone cement containing 5 mol% iron displayed good self-setting ability, me

The sites are 14C dated to the interval between the 19th–17th centuries BC. In the examined sample, the leading metallurgical group with a slight prevalence in both Petrovka and Alakul metals was “pure” copper; the second part of

Abstract:

Aesthetic preferences of contemporary art connoisseurs can hardly be called uniform. In view of this, today, heterogeneity, designed for a wide audience, is increasingly becoming a common technique. However, a question arises as to the reasons for the popularity of such eclecticism and ambiguity in the formation of an artistic image. The article is an attempt to scientific understanding of the formation and development of perception of images that differ in containing two or more strongly pronounced equivalent origins, which may exist with each other in contrast or be antagonistic.

Abstract Background Polyether-ether-ketone (PEEK) is increasingly being used for spinal applications. However, because of its biologically inactive nature, there are risks of false joint loosening and sinking. PEEK materials are coated with apatite to enhance the osteoconductive properties. In this study, we aimed to evaluate whether strontium apatite stimulate osteogenesis on the surface of PEEK by using the CO2 laser technique. Methods We prepared non-coated disks, laser-exposed disks without apatite, and four types of apatite-coated by laser PEEK disks (hydroxyapatite (HAP), strontium hydro

Abstract:

Anthony Giddens and a number of other social theorists and commentators see reflexivity as the guiding principle of modern self-identity (Giddens 1992; Beck). According to this thesis, reflexivity brings, at least potentially, a new level of knowledgeability, control and orderliness to one's experience of self. It ushers in a demystified world, geared towards calculability. In Giddens' own words, "....reflexivity refers to a world increasingly constituted by information rather than pre-modern modes of conduct. It is how we live after the retreat of tradition and nature, because of having to ta

Abstract:

The leitmotif of this Ph.D. thesis is represented by carbon dioxide (CO2) recycling via biological production of methane (CH4). This work particularly focuses on the physiology of three hydrogenotrophic methanogens, Methanothermobacter marburgensis (M. marburgensis), Methanothermococcus okinawensis (M. okinawensis) and Methanococcus maripaludis S2 (M. maripaludis), that can be used as catalysts for biological methane production (BMP) process. This CO2 recycling method is challenging due to an inefficient transfer rate of molecular hydrogen (H2) from the gas phase to the liquid phase. Thus, th
