Soil lacquer peel do-it-yourself: Simply capturing beauty
Stoof, Cathelijne R. ; Candel, Jasper H.J. ; Wal, Laszlo A.G.M. Van Der; Peek, Gert - \ 2019
SOIL 5 (2019)2. - ISSN 2199-3971 - p. 159 - 175.

Visualization can greatly benefit understanding of concepts and processes, which in soil science and geology can be done using real-life snapshots of soils and sediments in lacquer peels and glue peels. While it may seem complicated, anyone can make such a soil peel for use in classrooms, public places, homes, and offices for teaching, outreach, decoration, and awareness. Technological development has considerably simplified the making of soil peels, but this methodological innovation has not been described in the literature. Here, we report on a thoroughly tested and simple method for taking peels of sandy soils using readily available tools and materials. Our method follows the main previously published steps of preparing a soil face, impregnating the soil face with a fixation agent in the field, extracting the resulting peel, and mounting it on a wooden panel. Yet instead of using lacquers and thinning agents, we use strong though flexible contact adhesive (glue), which has the major advantage that it no longer requires use and mixing of toxic chemicals in the field or reinforcement of the peel to prevent breaking. Moreover, the preservation potential is much higher than with the old method. This new twist to old methods makes creation of soil peels safer, simpler, and more successful, and thereby a true DIY (do-it-yourself) activity. The resulting increased accessibility of making soil and sediment peels can benefit research, teaching, and science communication and can thereby bring the value and beauty of the ground below our feet to students, schools, policy makers, and the general public.

Total greenhouse gas (GHG) emissions from the Netherlands in 2015 increased by approximately 4%, compared with 2014 emissions. This increase was mainly the result of the increased electricity production in coal fired plants compared to 2014. Furthermore fuel combustion in all sectors was increased as the winter of 2015 was less mild as the one in 2014. In 2015, total GHG emissions (including indirect CO2 emissions and excluding emissions from Land use, land use change and forestry (LULUCF)) in the Netherlands amounted to 195.2 Tg CO2 eq. This is approximately 12.5% below the emissions in the base year2 (223.1 Tg CO2 eq). CO2 emission have increased above the level in the base year 1990 in 2015 (+ 1.5%). This increase was offset by the reduction in the emissions since 1990 of methane, nitrous oxide and fluorinated gases (CH4, N2O and F-gases). This report documents the Netherlands’ 2017 annual submission of its greenhouse gas emissions inventory in accordance with the 2006 IPCC Guidelines for National Greenhouse Gas Inventories (IPCC, 2006) provided by the United Nations Framework Convention on Climate Change (UNFCCC), the Kyoto Protocol and the European Union’s Greenhouse Gas Monitoring Mechanism. The report includes explanations of observed trends in emissions; an assessment of the sources with the highest contribution to the national emissions (key sources) and the uncertainty in their emissions; an itemization of methods, data sources and emission factors (EFs) applied; and a description of the quality assurance system and the verification activities performed on the data.
Resilience : The holy grail or yet another hype?
Milliano, Cecile De; Faling, Marijn ; Clark-Ginsberg, Aaron ; Crowley, Dominic ; Gibbons, Pat - \ 2015
In: The Humanitarian Challenge: 20 Years European Network on Humanitarian Action (NOHA) / Gibbons, P., Heintze, H.J., Springer International Publishing - ISBN 9783319134697 - p. 17 - 30.

Disaster risk is globally on the rise, mainly as a result of the complex interplay of environmental, demographic, technological, political and socioeconomic conditions that are expanding hazard and vulnerability profiles (Peek 2008). The inevitability of climatic change at both the global and the local level is generally accepted to be a fact, and various sources predict its dramatic impact on the planet and on humankind (Jones et al. 2010; UNICEF 2007; UNISDR 2004; Save the Children 2007). The field of disaster studies has consequently experienced a significant shift concerning both the nature of disasters, and ways to contend with them. Over the past few decades it has become accepted that disasters occur at the intersection of a natural hazard and people’s vulnerabilities, i.e. the organisation of society, with implications for the activities undertaken under the denominator of disaster management. That is, if disasters are inevitable, measures could only be directed at preparing people for a possible disaster to come-disaster preparedness-and assist them once a disaster had hit-disaster response. Approaching disasters as an intersection between nature and humankind on the other hand implies targeting underlying factors equally, including enduring vulnerability and people’s capacities. Following this trend, resilience thinking currently tops the agenda of disaster risk reduction, and yet the challenge in the coming period is to overcome the teething troubles of this approach. Indeed, resilience has the potential to become the next battleground for on-going debates on the purpose of humanitarian aid; i.e. whether it should be provided solely on the basis of identified needs, linked with development objectives, as part of broader coherence/whole of government agendas for wider change, or simply be a means of preserving the status quo-what Walker and Maxwell (2009) label as the '3 Cs’, compassion, containment, and change. To establish resilience as a useful approach to interventions rather than a political tool or point for debate, it is consequently valuable to pursue a mapping of the current discussions with regard to its promises and pitfalls. This chapter therefore provides an examination of the approach, without claiming to present an exhaustive list of issues. Rather, it is a careful exploration of experiences, both in theory as in practice of a resilience approach. The next section starts by discussing in more detail the shift that has taken place in thinking on disasters and their management.

self-assembled monolayers - contact-angle hysteresis - superoleophobic surfaces - superomniphobic surfaces - fabrication - friction - design - wettability - mechanism - adhesive
Superhydrophobic and superamphiphobic toward superoleophobic polymeric surfaces of polymethyl methacrylate (PMMA), polyether ether ketone (PEEK), and polydimethyl siloxane (PDMS) are fabricated in a two-step process: (1) plasma texturing (i.e., ion-enhanced plasma etching with simultaneous roughening), with varying plasma chemistry depending on the polymer, and subsequently (2) grafting of self-assembled perfluorododecyltrichlorosilane monolayers (SAMs). Depending on the absence or not of an etch mask (i.e., colloidal microparticle self-assembly on it), random or ordered hierarchical micro-nanotexturing can be obtained. We demonstrate that stable organic monolayers can be grafted onto all these textured polymeric surfaces. After the monolayer deposition, the initially hydrophilic polymeric surfaces become superamphiphobic with static contact angles for water and oils >153°, for hexadecane >142°, and hysteresis

Besides the anticoccidial drug resistance problem, increasing consumer concerns about food safety and residues have propelled the quest for alternative prevention and control strategies amongst which phytotherapy has gained appeal due to a renewed interest in natural medicine.Objective: The objective was in vivo screening of four phytochemicals/extracts and a fungal immunomodulatory protein (FIP) against an Eimeria acervulina infection in broilers.Animals and methods: Four phytochemicals/extracts (extract from Echinacea purpurea, betaine (Betain™), curcumin, carvacrol (two different doses)), and a recombinant FIP from Ganoderma lucidum cloned and expressed in Escherichia coli were investigated for their anticoccidial potential. The experiment was conducted in a battery cage trial with 54 cages of eight birds each. Broilers infected with E. acervulina (a low and high infection dose of 104 and 105 sporulated oocysts, respectively) and treated with the phytochemicals/extracts or the FIP were compared with broilers treated with the anticoccidial salinomycin sodium (Sacox®) and with an untreated uninfected and an untreated infected control group. Coccidiosis lesion scores, body weight gains and oocyst shedding were used as parameters.Results: The results showed a coccidiosis infection dose effect on the mean coccidiosis lesion scores. The phytochemicals/extracts and the FIP failed to reduce coccidiosis lesion scores and oocyst shedding, while salinomycin efficiently controlled the E. acervulina infection and enabled significantly higher body weight gains.Conclusion: In conclusion, the selected phytochemicals/extracts and the FIP did not reduce the lesions of an experimentally induced E. acervulina infection.

infectious-bronchitis virus - eimeria-tenella - immune-responses - dietary betaine - antimicrobial resistance - herb polysaccharides - commercial broilers - ganoderma-lucidium - escherichia-coli - chicks
Five phytochemicals/extracts (an extract from Echinacea purpurea, a ß-glucan-rich extract from Shiitake, betaine [Betain™], curcumin from Curcuma longa [turmeric] powder, carvacrol and also a recombinant fungal immunomodulatory protein [FIP] from Ganoderma lucidum) cloned and expressed in Escherichia coli were investigated for their anticolibacillosis potential in three chicken experiments, which were conducted in floor pens. Birds that were inoculated with E. coli intratracheally were treated with the phytochemicals/extracts or the FIP and compared with doxycycline-medicated and non-medicated infected broilers. Non-medicated and non-infected birds were used as negative controls. Mortality, colibacillosis lesions and body weight gains were used as parameters. Considering the sum of dead birds and chickens with generalized colibacillosis per group, there was no significant difference between the positive control groups and birds treated with phytochemicals/extracts or the FIP. In contrast, doxycycline-treated birds showed significantly lower mortality and generalized colibacillosis. Moreover, none of the phytochemicals/extracts and the FIP improved recovery from colibacillosis lesions, while all doxycycline-treated broilers recovered completely. The negative control birds and doxycycline-treated groups consistently showed the highest weight gains. Pulsed-field gel electrophoresis of reisolates showed that they were genetically indistinguishable from the inoculation strain. In conclusion, none of the tested phytochemicals/extracts and the FIP significantly reduced the E. coli-induced mortality and generalized colibacillosis, and nor did they improve recovery from colibacillosis lesions.

The formation of fluorinated monolayers with a minimized surface energy and an improved chemical stability on specific substrates will enable outstanding tribological properties and is the main goal of the research described in this thesis. Inorganic substrates, such as Si(111), silicon carbide (SiC), chromium nitride (CrN), and organic nano-micro-textured substrates such as PMMA, PDMS, PS and PEEK have been studied. Both fluorinated and non-fluorinated monolayers with a high packing density were obtained using functionally different surface attaching groups like alkenes, alkynes, enynes, silanes, and phosphonates. Most of these attaching moieties have been used before, but the deepening understanding of the factors that determine monolayer qualities allowed the development of even better attaching groups, like the ynenes.

Newly synthesized fluorinated alkyne-derived monolayers will be described exhibiting a minimized surface energy and an exceptionally low critical surface tension. The chemical stability in various aqueous media at different temperatures was also studied. Nano-tribology measurements were performed using atomic force microscopy (AFM) to verify a minimum in adhesion, friction and wear. The organic monolayers obtained on various surfaces in this study will be useful in MEMS/NEMS high performance industrial applications.

Total greenhouse gas emissions from The Netherlands in 2011 decreased by approximately 7 per cent compared with 2010 emissions. This decrease is mainly the result of decreased fuel combustion in the Energy sector (less electricity production) and in the petrochemical industry. Fuel use for space heating decreased due to the mild winter compared with the very cold 2010 winter. In 2011, total direct greenhouse gas emissions (excluding emissions from LULUCF – land use, land use change and forestry) in The Netherlands amounted to 194.4 Tg CO2 eq. This is approximately 9 per cent below the emissions in the base year 2 (213.2 Tg CO2 eq). This report documents the Netherlands’ 2012 annual submission of its greenhouse gas emissions inventory in accordance with the guidelines provided by the United Nations Framework Convention on Climate Change (UNFCCC), the Kyoto Protocol and the European Union’s Greenhouse Gas Monitoring Mechanism. The report comprises explanations of observed trends in emissions; a description of an assessment of key sources and their uncertainty; documentation of methods, data sources and emission factors applied; and a description of the quality assurance system and the verification activities performed on the data.
