Intensive livestock production involves environmental emissions and impacts, including emission of greenhouse gases and ammonia leading to climate change and terrestrial acidification. Ammonia emission from animal housing systems can be reduced by introducing air scrubbers for cleaning the exhaust air, but insight into the environmental impact throughout the entire system is lacking. This study aimed to assess and compare the environmental impact of three types of air scrubbers: an acid scrubber and two biotrickling filters, one with nitrification only and one with nitrification and denitrification. Air scrubbers were compared by using life cycle assessment and assessing five environmental impacts: climate change, terrestrial acidification, marine eutrophication, particulate matter formation and fossil fuel depletion. The acid scrubber showed reductions in all environmental impact categories (up to >2000%), whereas the biotrickling filter with combined nitrification and denitrification had highest climate change and fossil fuel depletion. The biotrickling filter with nitrification only had highest terrestrial acidification and marine eutrophication. © 2017 IAgrE

In this paper we focus on how to achieve better decision support when decision-makers use the ecosystem services (ESS) framework to broaden their evaluations. We contribute to the debate on valuation of ecosystem services by inquiring into how the ESS framework relates to the judgement and measurement provided by Cost-Benefit Analysis (CBA) and Multi-Criteria Analysis (MCA) evaluation techniques. We argue that Multi-Criteria Cost-Benefit Analysis (MCCBA), which is a carefully designed combination of CBA and MCA, provides a good starting point for the evaluation of projects or policies involving changes in agricultural and natural ecosystem services.The main characteristic of this MCCBA approach linked to ESS framework is its threefold evaluative endpoint structure to account for (i) basic health, (ii) economic welfare, and (iii) higher well-being. The third endpoint includes concerns about the well-being of nature. The MCCBA approach utilises highly standardised cardinal or ratio scale measurements, in particular we use two existing measurements, known as Disability Adjusted Life Years for basic health, and monetary Net Present Values for economic welfare. We also introduce one new measurement: Threat weighted Ecological Quality Area to account for nature's well-being. We argue that evaluation of projects or policies involving many different ecosystem services should use these three endpoint measurements. © 2012 Elsevier Ltd.

Obesity Reviews | Year: 2010

Insulin sensitizers like metformin generally act through pathways triggered by adenosine monophosphate-activated protein kinase. Carnitine palmitoyltransferase 1 (CPT1) controls mitochondrial β-oxidation and is inhibited by malonyl-CoA, the product of acetyl-CoA carboxylase (ACC). The adenosine monophosphate-activated protein kinase-ACC-CPT1 axis tightly regulates mitochondrial long-chain fatty acid oxidation. Evidence indicates that ACC2, the isoform located in close proximity to CPT1, is the major regulator of CPT1 activity. ACC2 as well as CPT1 are therefore potential targets to treat components of the metabolic syndrome such as obesity and insulin resistance. Reversible inhibitors of the liver isoform of CPT1, developed to prevent ketoacidosis and hyperglycemia, have been found to be associated with side effects like hepatic steatosis. However, stimulation of systemic CPT1 activity may be an attractive means to accelerate peripheral fatty acid oxidation and hence improve insulin sensitivity. Stimulation of CPT1 can be achieved by elimination or inhibition of ACC2 activity and through activating transcription factors like peroxisome proliferator-activated receptors and their protein partners. The latter leads to enhanced CPT1 gene expression. Recent developments are discussed, including a recently identified CPT1 isoform, i.e. CPT1C. This protein is highly expressed in the brain and may provide a target for new tools to prevent obesity. © 2009 International Association for the Study of Obesity.

In 2011, northern fulmars (Fulmarus glacialis) from Iceland were used to test the hypothesis that plastic debris decreases at northern latitudes in the Atlantic when moving away from major human centres of coastal and marine activities. Stomach analyses of Icelandic fulmars confirm that plastic pollution levels in the North Atlantic tend to decrease towards higher latitudes. Levels of pollution thus appear to link to regions of intense human coastal and marine activities, suggesting substantial current inputs in those areas. © 2012 Elsevier Ltd.

Ecological Economics | Year: 2012

Given the major changes that rural areas have undergone, and are continuing to undergo, serious problems of achieving sustainable development are being experienced. These changes have multiple characters, varying from changes in ecosystem conditions to changes in socio-economic impacts, due to, for example, food- and financial crises. Nowadays, there is an increasing awareness of the need to develop rural policies that support adaptive strategies of stakeholders in response to a disturbance. We propose that resilience thinking offers a framework that could be helpful in the governance of rural changes. This framework is based on the complexity of the social-ecological system and takes into account the unpredictable future, as it emphasizes adaptive approaches to management. As such, it helps evaluate to what extent rural development policies contribute to the resilience of rural areas. Nine criteria were developed including thirteen specifications. In order to evaluate the usability and usefulness of the proposed framework, a case study has been performed that specifically investigated the degree of resilience of a European rural development policy (i.e. the spending of extra funds generated through compulsory modulation under the 2009 Health Check in the Netherlands). © 2012 Elsevier B.V.

Because L-carnitine (l-CAR) is a potential substitute for neonatal dexamethasone (DEX) with respect to the prevention of long-term side effects, rats were treated on d 1, 2, and 3 after birth with saline, DEX, l-CAR, half the dose of DEX, and l-CAR + half DEX. DEX led to growth retardation, increased mortality, and severe kidney damage at 50 wk of age. l-CAR had no negative effects on growth, kidney function at 50 wk, and survival at 101 wk. Growth retardation was induced transiently by half DEX and permanently by l-CAR + half DEX, slightly reduced kidney function but no reduced life span was found in both these groups. Except for the DEX group, blood glucose levels were normal at 50 wk in all groups. A serendipitous finding was that l-CAR treatment caused one-third less food intake; however, these rats maintained normal body weight. In conclusion, l-CAR, a lower dose of DEX, and their combination caused less negative effects in later life. Because l-CAR + half DEX had a negative effect on growth, attention to monitor l-CAR levels during DEX treatment of preterm newborns seems to be justified. The finding that neonatal l-CAR caused reduced food intake in later life warrants further investigation. Copyright © 2011 International Pediatric Research Foundation, Inc.

Two female polar bears at Dierenrijk Zoo in the Netherlands were monitored at their maternity den one day before the birth of their cubs and three days postpartum. Each bear was monitored for 96hr to document behaviour and vocalisations. The goal was to obtain insight into the differences between the mother that lost her litter and the other that successfully reared her cubs. Six groups of cub vocalisations were identified: Comfort, Discomfort, Distress, Nursing Attempts, Nursing, and No Vocalisation. Maternal vocalisations were split into three groups: Calm, Grooming, and Stress. Maternal behaviours were also split into three groups: Active, Rest, and Stress. The unsuccessful mother produced more stress vocalisations before and during the birth of her cub, whereas the successful mother appeared less stressed. Vocalisations indicate that the cub that died tried to nurse but was unsuccessful. The unsuccessful mother showed less stress as her cub got weaker and vocalised less. From this I suggest that maternal stress was a factor in cub mortality. © 2015 Wiley Periodicals, Inc.

Data on beach debris and tar contamination is provided for 21 natural beach sites in Bonaire, Southeastern Caribbean. Transects amounting to a combined length of 991m were sampled March-May 2011 and a total of 8960 debris items were collected. Highest debris and tar contamination were found on the beaches of the windward east-coast of the island where geometric mean debris concentrations (± approx. 70% confidence limits) were 115±58itemsm-1 and 3408±1704gm-1 of beach front. These levels are high compared to data collected almost 20years earlier on the nearby island of Curaçao. Tar contamination levels averaged 223gm-1 on windward beaches. Contamination levels for leeward west-coast beaches were generally two orders of magnitude less than windward beaches. © 2013 Elsevier Ltd.

The current study seeks to investigate the relationship between perceived equine and rider personality traits on the one hand and quality of horse-rider relationships on the other. An Internet questionnaire examined the self-perceived personality traits of 2525 horse-female rider dyads that indicated to have a low, medium or high-quality horse-rider relationship. The questionnaire was split into three parts, part 1 focused on personal details, while parts 2 and 3 investigated perceived personality traits of the rider (15 items) and the horse (15 items). In order to determine relevant personality components contained in the rider and horse personality questionnaires, principal components analyses (PCA) were performed. The following personality components could be identified for the rider: "excitability", "liveliness", "consideration" and "leadership" For the horse, relevant components consisted of "emotional reactivity", "intelligence", "gregariousness", and "willingness to work" Partial correlations were used to investigate relationships between horse and rider personality components, while controlling for the effect of length of ownership and competitive level. Weak positive partial correlations were found between the personality components of "liveliness (rider)" with "intelligence (equine)" [r= 0.16, n= 1674, P< 0.0001] and "gregariousness (equine) [r= 0.1, n= 1674, P< 0.001]; "excitability (rider)" with "emotional reactivity (equine)" [r= 0.14, n= 1674, P< 0.0001]; "leadership (rider)" with "intelligence (equine)" [r= 0.1; n= 1674; P< 0.0001] and "willingness (to work) (equine)" [r= 0.1, n= 1674; P< 0.0001]; "consideration (rider)" with "gregariousness (equine)" [r= 0.11; n= 1674; P< 0.0001] Our findings suggest that self-perceived personality traits in the rider at least in part co-vary with perceptions of horse temperament, and, as a consequence, are likely to affect quality perceptions of horse-rider interaction. © 2012 Elsevier B.V.
