Sustainability assessment (SA) is a complex appraisal method. It is conducted for supporting decision-making and policy in a broad environmental, economic and social context, and transcends a purely technical/scientific evaluation. This paper focusses on the systematisation of knowledge on technical/scientific sustainability evaluation, by addressing critical decision-making elements focussed on by domain experts. We make a distinction between integrated assessment and SA. Our systemic approach outlines how to move from integrated assessment to SA. The fundamental differences involved concern three levels: ontological, methodological and epistemological. We present a novel methodological framework for SA, based on a literature meta-review of multi-scale and multi-purpose appraisal methodologies, models and indicators. SA is essentially a structured procedure encompassing different field-specific analytical methods and models, for specific applications and decision contexts. External inputs to the methodology are "values" considered in the analysis and boundaries defined, including the relevant sustainability framework. Internal methodological elements comprise approach to be adopted (e.g. "what-if" vs. "what-to"), scenario design and analytical models and measurable indicators for an operational analysis. Methods to quantify uncertainty are key ingredients of the assessment framework. The paper highlights the relevance of and policy challenges for SA development, with due attention for applicability in real-world decision contexts. © 2015 The Authors.

8-Quinolinecarboxaldehyde thiosemicarbazone (HL) and copper form compounds with a metal: ligand ratio of 1: 1 in which the ligand is either the neutral molecule or the monohydric acid anion. Its acidic properties are enhanced not only as a result of coordination but also due to the electronic effect of substituents in the thiosemicarbazide moiety. 8-Quinolinecarboxaldehyde 4-phenylthiosemicarbazone (HL1) is coordinated only as the anion. The structures of [Cu(HL)SO4]2, [Cu(L)NO3] 2, and [Cu(L1)NO3]2 • 0.25H2O, and free HL1 were studied. The tendency of the complexes to dimerization and association with acid anions or sulfur atoms of the organic ligands as bridges was established. In binuclear compounds with closely spaced magnetic centers, no exchange interaction between them was found. The copper coordination compounds with HL are able to suppress the growth of cancer cells 41M and SK-BR-3 and are promising objects for investigation as anticancer drugs. © 2010 Pleiades Publishing, Ltd.

New cobalt trans-dioximate complexes with isoniconinamide have been synthesized: [CoII(DmgH)2(Inia)2] (I), [Co III(DmgH)2(Inia)2][PF6] · 1.5H2O (II), [CoIII(NioxH)2 (Inia) 2][PF6] · H2O · CH3OH (III), and [CoIIICl(DmgH)2(Inia)] · H2O (IV), where DmgH- and NioxH- are the dimethylglyoxime and 1,2-cyclohexanedionedioxime monoanions, respectively; Inia is the isonicotinamide molecule. The structures of compounds I-IV have been determined by X-ray crystallography. In I-IV, Co(II) or Co(III) has an octahedral environment with the pseudomacrocyclic (DioxH-)2 moiety (DioxH- is the dioximate monoanion) in the equatorial plane. The latter is stabilized by O-H⋯O hydrogen bonds. The isonicotinamide molecules in all four complexes are monodentately bound to the metal ion through the heterocyclic nitrogen atom. © Pleiades Publishing, Ltd., 2011.

Condensation of 3-hydroxyamino-3-methylbutan-2-one with thiosemicarbazide afforded 3-hydroxyamino-3-methylbutan-2-one thiosemicarbazone as a new ligand (H2L). Cobalt(III) and nickel(II) complexes with this ligand were obtained. The molecular formulas and structures of the thiosemicarbazone and the complexes [Co(HL)2]Cl · 2H2O (I) and [Ni(H2L)2]Cl2 · 2.25H2O (II) were confirmed by elemental analysis, IR spectroscopy, and X-ray diffraction (CIF files CCDC nos. 985065 (H2L), 985066 (I), and 985067 (II)). The crystal structures of the ligand H2L and complexes I and II were determined. The way in which the ligand is coordinated to the metal ions, its conformational changes upon the complexation, and the packing patterns in the crystals of H2L, I, and II are discussed. © 2014 Pleiades Publishing, Ltd.

Background: When infected with seed-transmitted fungal endophytes, some grasses produce a larger quantity of seeds, although these seeds are smaller than normal. The principles of life-history theory suggest that this size reduction could evolve if the infection reduces predation pressure. Question: Does the endophyte protect grass seedlings against herbivory? Hypothesis: Herbivores consume more seedlings that develop from endophyte-free grass seeds than from endophyte-infected grass seeds. Organisms: Epichloë typhina is the seed-transmitted endophytic fungus, the weeping alkaligrass (Puccinellia distans) seedlings are the hosts, and the grove snail (Cepaea nemoralis) is the herbivore. Methods: Our experiment consisted of two 66-h food-choice tests. The tests were performed consecutively and on the same individual snails. We offered snails freshly harvested weeping alkaligrass seedlings with and without the endophyte. Results: Starved snails consumed approximately 20% less biomass of infected seedlings than uninfected seedlings. When the same snails were tested again shortly after their first contact with the endophyte, they exhibited an approximately 40% reduction in seedling consumption, and food discrimination became undetectable. Conclusions: Toxins produced by endophytic fungi reduce the vulnerability of grass seedlings to snail herbivory © 2010 Marlena Lembicz.

We present a micromagnetic approach to the exchange bias in ferromagnetic/antiferromagnetic thin film systems with a small number of irreversible interfacial magnetic moments. We express the exchange bias field HEB in terms of the fundamental micromagnetic length scale of ferromagnetic - the exchange length lex. The benefit from this approach is a better separation of the factor related to the ferromagnetic layer from the factor related to the ferromagnetic/antiferromagnetic coupling at interfaces. Using this approach we estimate the upper limit of HEB in real ferromagnetic/antiferromagnetic systems.

The crystalline structure of chlorpropamide is studied by the X-ray diffraction method at high pressures up to 4.2 GPa and in the temperature range 300-450 K. At normal pressure and upon heating to its melting point T = 396 K no phase transitions are found in chlorpropamide. When the initial α form of chlorpropamide is recrystallized, the appearance of a polymorphic ε phase is observed. After recrystallization, the high pressure effect causes partial amorphization of chlorpropamide at pressures of P ∼ 3 GPa. Baric and temperature coefficients are obtained for the α and ε forms of chlorpropamide. © 2013 Pleiades Publishing, Ltd.

Our palaeoecological study covers 73 years of history (1929-2002) of a kettle hole peatland inundated by water from a nearby, dammed lake. Testate amoebae, pollen and non-pollen palynomorphs (NPPs) were used to track the shift to wetter conditions in the peatland. Lead-210 was used to try and construct the chronology. We investigated how peatland testate amoebae communities changed since the damming of a nearby river. Furthermore, we evaluated how rapidly local vegetation responded to the increase in wetness, and how vegetation changes correlated with shifts in testate amoebae and NPPs. The Mukrza kettle hole provided palaeoecological evidence of trophic state and hydrological changes since the lake filled with water in 1929. Three stages of development were revealed. The first two were associated with initial inundation, and the third was related to Sphagnum expansion and acidification. Quantitative reconstruction of groundwater level and pH, inferred using testate amoebae, confirmed our hypotheses about changes in hydrology and trophic state. Subfossil desmid remains lend qualitative support to the reconstruction. The ecology of several testate amoeba taxa is discussed in the context of succession and population establishment. There was complete species replacement since the time of inundation. Our investigation has two important applied aspects: (1) it enables prediction of the response of peatlands to a rise in water table on restored sites; and (2) it provides analogues for palaeoclimatological studies. The history of the Mukrza mire is an example of how palaeoecological studies can be used to assess the degree of change in peatlands transformed by human activities. © Springer Science+Business Media B.V. 2009.
