Acute Toxicity of Experimental Fertilizers Made of Spent Coffee Grounds

2017

Sustainable agriculture places new demands on agricultural practice and, in particular, plant protection treatments and fertilization. Therefore, an increase in demand for organic fertilizers of good quality is expected. In particular, the organic matter contained in the waste of the food industry or generated in households, in the absence of contamination, can be used for the production of “fertilizer”, which could be used in organic crop production. The paper presents basic characteristics of tested mixtures and the results of testing for acute toxicity of the mixture made from spent coffee grounds (SCG) modified with ash arising from the low-temperature combustion of biomass or magnesium…

Quantifying submarine groundwater discharge in the coastal zone via multiple methods

2006

Submarine groundwater discharge (SGD) is now recognized as an important pathway between land and sea. As such, this flow may contribute to the biogeochemical and other marine budgets of near-shore waters. These discharges typically display significant spatial and temporal variability making assessments difficult. Groundwater seepage is patchy, diffuse, temporally variable, and may involve multiple aquifers. Thus, the measurement of its magnitude and associated chemical fluxes is a challenging enterprise. A joint project of UNESCO and the International Atomic Energy Agency (IAEA) has examined several methods of SGD assessment and carried out a series of five intercomparison experiments in di…

Acute toxicity of experimental fertilizers made of blood meal, spent coffee ground and biomass ash

2017

Abstract The study presents the results of research on the acute toxicity of a fertilizer formulas made of spent coffee ground (SCG) with addition of ash from low-temperature combustion of biomass or ash with an admixture of magnesium sulphate and blood meal. The experimental fertilizer formulas included also rape oil used as a plasticizer for controlling the nutrients release from the fertiliser. Mustard (Sinapis alba L.), oats (Avena sativa sp. L.), cucumber (Cucumis sativus L.) and cress (Lepidium sativum L.) were used as test plants species in the experiment. The toxicity tests were performed using a standard procedure of 72 h with the use of Phytotoxkit microbiotest and fertilizer appl…

Conceptual Spaces for Cognitive Architectures: A lingua franca for different levels of representation

2017

During the last decades, many cognitive architectures (CAs) have been realized adopting different assumptions about the organization and the representation of their knowledge level. Some of them (e.g. SOAR [Laird (2012)]) adopt a classical symbolic approach, some (e.g. LEABRA [O'Reilly and Munakata (2000)]) are based on a purely connectionist model, while others (e.g. CLARION [Sun (2006)] adopt a hybrid approach combining connectionist and symbolic representational levels. Additionally, some attempts (e.g. biSOAR) trying to extend the representational capacities of CAs by integrating diagrammatical representations and reasoning are also available [Kurup and Chandrasekaran (2007)]. In this p…

To make room or not to make room: clients’ narratives about exclusion and inclusion of spirituality in family therapy practice

2017

This empirical article presents four narratives from an ongoing qualitative PhD project about spirituality and family therapeutic practice. Using case studies and narrative vignettes, the article presents client perspectives on being able to discuss their spirituality in therapy, and the repercussions when therapists exclude it. The article refers to current research and provides some reflections on how we can understand spirituality in the context of family therapeutic practice; therapists for holistic, cultural, and ethical reasons should acknowledge the client’s spirituality. Therapists need to reflect on their own spirituality and how it may influence their relationships with clients. n…

Fall of Potential Measurement of the Earth Resistance in Urban Environments: Accuracy Evaluation

2019

Both Standards EN 50522 and IEEE 81 propose the fall of potential method (FPM) to carry out the measurement of the resistance to earth ( $R_{\text{ES}}$ ) of an earthing system (ES). However, in urban areas, the recommended distances between the ES and auxiliary electrodes are not easy to respect, due to the presence of buildings and tarmac. Furthermore, unknown buried metallic parts and interconnections among ESs could modify the earth potential profile of the area, affecting the measurement results. In this paper, the key-issues that influence the measured $R_{\text{ES}}$ when the FPM is used in an urban environment are presented. A parametric analysis, carried out with Comsol Multiphysic…

Trajectory tracking for an Ultralight WIG

2007

In this paper we present our research about a particular ultralight WIG. We have carried out the design of a Flight Control System that has to fix the control variables trend through a non-linear mathematical model, because of the particular geometric and aerodynamic configuration of this WIG. So, the non-linear mathematical model design has to reproduce exactly the aircraft behaviour either OGE or IGE. In particular, through classical semi-empirical relations, analytical equations have been obtained in order to evaluate incidence variations, downwash and upwash angles due to the ground. In the present paper only longitudinal dynamic is considered, because of its peculiarity in WIG's aircra…

Basis for a general theory of organizations

2011

Purpose – The purpose of this paper is to identify the conceptual basis shared by different theories, regardless of the unit of analysis they specifically adopt. The different ontological choice (or different segment of reality studied by each theory) does not hinder conceptual common ground for a good number of organisational theories.Design/methodology/approach – The paper highlights the importance of hierarchical, social and institutional relations and of the technological, cognitive, social and institutional contents. It looks at the common conceptual contents of the two main theories examined, and those of a wide set of other theories addressed here. Both of the theories examined are i…
