Assessment of Arundo donax Fibers for Oil Spill Recovery Applications

2019

In the last years, natural fibers are increasingly investigated as an oil recovery system in order to overcome the oil spillage phenomena, thus preserving environment and aquatic life. In particular, lignocellulose-based fibers have recently been employed with promising results. In such a context, the aim of this paper is to assess the oil sorption capability of natural fibers extracted from the stem of the giant reed Arundo donax L., a perennial rhizomatous grass belonging to the Poaceae family that grows naturally all around the world thanks to its ability to tolerate different climatic conditions. Sorption tests in several pollutants and water as a reference were carried out. The fibers …

Life-Cycle Land-Use Requirement for PV in Vietnam

2021

Over the last 15 years, photovoltaics (PV) in Vietnam has experienced development. The increased installed capacity of PV requires more land for installation sites as well as for manufacturing the plants’ component and waste treatment during the plants’ decommissioning. As a developing country, in which more than 80% of the population’s livelihood depends on agriculture, there are concerns about the competition of land for agriculture and solar development. This paper estimates the life-cycle land-use requirement for PV development in Vietnam, to provide the scientific-based evidence for policy makers on the quantity of land required, so that the land budget can be suitably allocated. The d…

Insights into food system exposure, coping capacity and adaptive capacity

2017

Purpose The purpose of this paper is to consider the concepts of exposure, coping capacity and adaptive capacity as a multiple structure of vulnerability in order to distinguish and interpret short-term coping responses and long-term strategic responses to food system vulnerability. Design/methodology/approach This paper applies an abductive approach for qualitative analysis of data, which were collected through 18 semi-structured interviews among Finnish food system actors. Findings The findings suggest that coping capacity and adaptive capacity are indeed two different concepts, which both need to be addressed in the examination of food system vulnerability. Public and private food syste…

Application of multivariate analysis techniques for selecting soil physical quality indicators: A case study in long-term field experiments in Apulia…

2019

Long-term field experiments and multivariate analysis techniques represent research tools that may improve our knowledge on soil physical quality (SPQ) assessment. These techniques allow us to measure relatively stable soil conditions and to improve soil quality judgment, thereby reducing uncertainties. A monitoring of SPQ under long-term experiments, aimed at comparing crop residue management strategies (burning vs. incorporation of straw, FE1) and soil management (minimum tillage vs. no tillage, FE2), was established during the crop growing season of durum wheat. The relationships between five SPQ indicators (bulk density [BD], macroporosity [PMAC], air capacity [AC], plant available wate…

Non-specific bronchial hyper-responsiveness in children with allergic rhinitis: relationship with the atopic status

2003

An increased prevalence of bronchial hyper-responsiveness (BHR) has been demonstrated in children from a general population, and in non-asthmatic adults with allergic rhinitis. Thus, also children with allergic rhinitis are expected to be at higher risk of BHR. We evaluated the prevalence of BHR in a sample of non-asthmatic children with allergic rhinitis by means of the methacholine (Mch) bronchial challenge, and by monitorizing the airway patency using the daily peak expiratory flow variability (PEFv). Fifty-one children (ranged 6-15 years of age) with allergic rhinitis, ascertained by skin prick test to inhalant allergens, underwent a 14-day peak expiratory flow monitoring, and a Mch bro…

Biaxial deformation and ductility domains for engineered rectangular RC cross-sections: A parametric study highlighting the positive roles of axial l…

2016

Abstract Axial load and biaxial bending strongly influence the deformation capacity of column cross-sections, in most cases causing a non-negligible loss of curvature and ductility with respect to the case of pure bending along principal axes, commonly assumed as the basic condition to assess the inelastic capacity. In consideration of this the paper investigates the biaxial deformation performance of RC rectangular cross-sections belonging to one-dimensional elements, focusing on the influence of some parameters as the cross-section aspect ratio and the distribution of the rebars, as well as the mechanical characteristics of concrete and steel and the impact of biaxial/axial stresses. In t…

Country-specific differences of age stereotypes towards older hospital staff and their association with self-efficacy, work ability and mental well-b…

2020

To compare stereotypes towards older workers between hospital staff in Germany and Latvia and to analyse the relationship between those stereotypes and self-efficacy, subjective work ability and irritation.Cross-sectional study.In 2018, hospital staff, including nurses, physicians and other professions, of two German and three Latvian hospitals were asked to complete the standardized study questionnaire on subjective work ability, occupational self-efficacy, irritation and stereotypes towards older workers. In the latter scale older workers were defined as ≥45 years of age and the scale ranged from 27-135 whereby higher values reflect higher levels of positive stereotypes. To analyse the re…

EFFECTS OF CUSTOMER KNOWLEDGE MANAGEMENT AND CUSTOMER ORIENTATION ON INNOVATION CAPACITY AND MARKETING RESULTS IN SMEs: THE MEDIATING ROLE OF INNOVAT…

2018

Managing customer knowledge is a key of source for SMEs. The principal aim of this paper is to provide empirical evidence on the direct effects of two specific strategic resources: customer orientation and customer knowledge management (CKM), on innovation capacity and marketing results in SMEs. The study also examines the role of innovation orientation as a mediator between customer orientation and CKM. For this purpose, a structural model was proposed and tested through an empirical investigation with variance-based structural equation modeling (PLS) using a sample made up of 210 Spanish SMEs. The findings highlight the relevance of CKM and customer orientation as important strategic res…

Pulsed-field gel electrophoresis for the discrimination of Oenococcus oeni isolates from different wine-growing regions in Germany

2008

Reliable techniques are needed for the identification individual Oenococcus oeni strains with desirable flavor characteristics and to monitor the survival and contribution of inoculated and indigenous bacteria. Therefore, we investigated the suitability of pulsed-field gel electrophoresis (PFGE) for the discrimination of 65 O. oeni isolates from six different wine-producing regions in Germany. Among the restriction enzymes tested, genomic DNA digestions with Sfi I were most effective by displaying 56 (86%) different banding profiles. Our results underline the high capacity of PFGE for strain identification and differentiation. Cluster analysis of the DNA restriction patterns revealed no dis…
