Container experiments yearly report 2022
Container experiments investigating leaching from alum shale under different conditions were started autumn 2020 as a part of the Under Oslo project at NGI (SP13). Furthermore, leaching from alum shale mixed with different amounts of rhomb porphyry was investigated, giving a total of 14 containers. The black shale in these containers were taken out from a road cut by E16 at Kleggerud autumn 2020. Additionally, 5 containers set up by the Norwegian Public Road Authorities (Statens vegvesen, SVV) in 2014 and 2015 to investigate leaching from alum shale and Galgeberg shale originating from the construction of the tunnel at Gran, Rv. 4, were taken over by NGI and measurements of leachate quality were resumed in November 2020. Autumn 2021 another two containers from SVV were taken over by NGI.Norges forskningsrĂĄ
The Inactivation of a New Peptidoglycan Hydrolase Pmp23 Leads to Abnormal Septum Formation in Streptococcus pneumoniae
The bacterial peptidoglycan is the major component of the cell wall which integrity is essential to cell survival. In a previous work, we identified, in the positive-Gram pathogen Streptococcus pneumoniae , a unique protein containing a new putative peptidoglycan hydrolytic domain named PECACE (PEptidoglycan CArbohydrate Cleavage Enzyme). In this study, we characterise the physiological function of this protein called Pmp23 (Pneumococcal Membrane Protein of 23 kDa). A cell wall hydrolytic activity is observed with the recombinant protein. Inactivation of the pmp23 gene in the pneumococcus led to a decreased flocculation, an increased sensitivity to β-lactam antibiotics and morphological alterations affecting the formation and localisation of the division septa. Taken together these observations indicate that Pmp23 is a hydrolase whose function is linked to peptidoglycan metabolism at the septum site

Ecological implications of pedogenesis and geochemistry of ultramafic soils in Kinabalu Park (Malaysia)
In Sabah, Malaysia, ultramafic rock outcrops are widespread (totalling 3500 km2, one of the main outcrops in the tropical zone), and predominantly of the peridotite type. However, strongly serpentinised peridotite is also locally common, particularly along fault lines in the Mt. Kinabalu area. This study aimed to determine the extent of chemical variation in ultramafic soils in relation to the degree of serpentinisation and the weathering intensity, and consequent potential ecological implications linked to resulting soil chemical fertility. It was hypothesized that young soils and soils derived from bedrock with a significant degree of serpentinisation strongly differ from typical Geric Ferralsols and result in soil chemistries with more adverse properties to plant life (e.g. low availability of the essential nutrients N, P, K and Ca and high concentrations of potentially phytotoxic Mg and Ni). Ultramafic soil diversity linked to the age of the soil or the degree of serpentinisation would thus be a main factor of plant diversity and distribution. The diverse topography of Kinabalu Park (ultramafic soils present between 400 and 2950 m asl) has given rise to high pedodiversity with the broad overall ultramafic soil types being: (i) deep laterite soils (Geric Ferralsols); (ii) moderately deep montane soils (Dystric Cambisols) with mor humus; (iii) shallow skeletal soils at high altitude (Eutric Cambisols Hypermagnesic); and (iv) bare serpentinite soils (Hypereutric Leptosols Hypermagnesic) at low altitude (200–700 m asl). Leptosols on serpentinite and Eutric Cambisols have the most extreme chemical properties in the whole Kinabalu Park area both with very high Mg:Ca molar quotients, with either high available Ni (Cambisols) or high pH (Leptosols). These soils host specific and adapted vegetation (high level of endemism) that tolerates geochemical peculiarities, including Ni hyperaccumulators. Geric Ferralsols present far less chemical constraints than Hypermagnesian Cambisols soils to the vegetation and host a tall and very diverse rainforest, not so different than that on non-ultramafic soils. It therefore appears that altitude, soil age and degree of bedrock serpentinisation are the main determining factors of soil properties: the qualifier “ultramafic” alone is not sufficient to define soil geochemical and ecological conditions in the Kinabalu Park area, probably more than in any other ultramafic region in the world
Manganese and cobalt redox cycling in laterites; Biogeochemical and bioprocessing implications
This research was developed during the PhD studies of AgustĂn Solano Arguedas in the University of Manchester, United Kingdom. PhD scholarship was funded by the Ministerio de Ciencia, TecnologĂa y Telecomunicaciones (MICITT) of the Government of Costa Rica and the Universidad de Costa Rica (UCR). AgustĂn Solano Arguedas is a researcher at the Unidad de Recursos Forestales (Reforesta, Unit of Forest Resources) of the Instituto de Investigaciones en IngenierĂa (INII, Engineering Research Institute), UCR.Cobalt is essential for the modern technology that underpins the decarbonisation of our economies, but its supply is limited leading to its designation as a critical metal. Cobalt biogeochemistry is poorly understood, yet knowledge of how biogeochemical cycling impacts cobalt behaviour could assist the development of new techniques to recover cobalt from ores, and so improve the security of supply. Laterites are an important source of cobalt, they are primarily processed for nickel using energy or chemical intensive processes, with cobalt recovered as a by-product. Metal-reducing conditions were stimulated in laterite sediment microcosms by the addition of simple and cheaply available organic substrates (acetate or glucose). At the end of the experiment the amount of easily recoverable cobalt (aqueous or extractable with acetic acid) increased from < 1% to up to 64%, which closely mirrored the behaviour of manganese, while only a small proportion of iron was transformed into an easily recoverable phase. Sequencing of the microbial community showed that the addition of organic substrates stimulated the growth of indigenous prokaryotes closely related to known manganese(IV)/iron(III)-reducers, particularly from the Clostridiales, and that fungi assigned to Penicillium, known to produce organic acids beneficial for leaching cobalt and nickel from laterites, were identified. Overall, the results indicate that the environmental behaviour of cobalt in laterites is likely to be controlled by manganese biogeochemical cycling by microorganisms. These results are compelling given that similar behaviour was observed in four laterites (Acoje, ÇaldaÄź, PiauĂ and Shevchenko) from different continents. A new bioprocessing strategy is proposed whereby laterites are treated with an organic substrate to generate metal-reducing conditions, then rinsed with acetic acid to remove the cobalt. Not only are organic substrates environmentally-friendly and potentially sourced from waste carbon substrates, a minimal amount of iron oxides was mobilised and consequently less waste generated.Natural Environment Research Council/[CoG3 NE/M011518/1]/NERC/Reino UnidoDiamond Light Source/[SP16735]//Reino UnidoDiamond Light Source/[SP17313]//Reino UnidoOffice of Science User Facility/[DE-AC02-05CH11231]//Estados UnidosUCR::VicerrectorĂa de InvestigaciĂłn::Unidades de InvestigaciĂłn::IngenierĂa::Instituto Investigaciones en IngenierĂa (INII
Explaining reforms: post-New Public Management myths or political realities? Social housing delivery in England and France
France, immigration, and the policies of Culture: understanding the “French Integration Model”.
The common understanding of immigration in France tends to emphasise republican principles as a critical element to approaching the integration of immigrants in France. This gives major agency to republican institutions, such as the educational system, and assumes that the state has been blind to any specific ethnic belonging. Immigrants have been given, equal access to republican institutions thus allowing equal chances of success. However, in an effort to bring historical perspective to the practice of integration policies in France, I argue against the myth of the republican model. Policy makers have made practical decisions to cope with various situations, and as a result have often contradicted republican principles. Immigrants have been considered according to an underlying hierarchy of origin and cultural programs have been designed to approach each national group differently. I provide concrete evidence for the argument that highlights a discrepancy between the political discourse of a French model of integration at the core of the republic versus the reality of the policy making. By focusing on the cultural components of immigration policies I argue that discussions around cultural diversity are critical to understand the formation of French integration policy. Drawing on extensive research in the governmental archives from the 50’s to the 80’s, this paper investigates the state’s position on cultural diversity throughout the years in order to provide direct insight on integration policies. Firstly, the paper focuses on the cultural component of social programs designed to ease immigrant integration into the country during the post-colonial period. Secondly, the paper explores the state’s position on cultural diversity by investigating the discussion on immigrant culture in the Ministry of Culture. Thirdly, the paper provides a comparative perspective with the United States
