Food Security Is None Of Your Business? Food Supply Chain Management In Support Of A Sustainable Food System
2017
Food security is the principal outcome of any given food system and it can be defined in terms of a sustainable food system where the core goal is to feed everyone sustainably, equitably and healthily. A sustainable food system addresses needs for availability, affordability and accessibility, is diverse, ecologically-sound and resilient, and builds the capabilities and skills necessary for future generations. This paper identifies the essential elements of food supply chain management in support of a sustainable food system, which ultimately enhances food security. The existing food supply chain and food system literature is synthesized in order to study the correspondence between public i…
Impact of humic acids on EYL liposome membranes: ESR method
2015
Abstract In this paper, the effects of model (commercial) and natural (extracted from peat) humic substances on the membrane of liposomes formed with egg yolk lecithin (EYL) are presented. In our research, mass concentrations of fulvic and humic acids were used, which in relation to lecithin varied from 0% to 13%. To study membrane fluidity, electron spin resonance (EPR) was used with two spin probes, penetrating various regions of the lipid bilayer. The effects of model and natural humic substances (humic acids – HAs and fulvic acids – FAs) on the lipid membrane in different regions were researched: the lipid-water interphase, and in the middle of the lipid bilayer. It was shown that FA an…
Memory‐type control charts for censored reliability data
2023
Control charts are commonly used to monitor a process to detect undesirable changes. The main goal of this work is to propose exponentially weighted moving average (EWMA) and cumulative sum (CUSUM) control charts to track a process by utilizing type-I censored generalized exponential (GE) distributed data. In particular, the censored data are replaced with the conditional expected value (CEV). A comparison between CUSUM and CUSUM ignoring unobserved covariates (CUSUM-IUC) charts is also a part of this study. The GE distribution is considered due to its application in reliability analysis. The performance of the charts is evaluated by using the average run length along with the standard devi…
Union representation and prevention of occupational risks during the crisis: impact and limits
2019
La investigación que presentamos estudia el impacto de la intervención sindical en materia de salud laboral, en lo que se refiere tanto a la gestión preventiva y creación de una cultura participativa como en los procesos de vigilancia y control de las condiciones de trabajo. A tal efecto, se han consultado las principales encuestas nacionales e internacionales sobre gestión de riesgos laborales en las empresas, analizando los datos más relevantes en base a modelos de regresión logística y lineal, lo que ha permitido constatar que la representación sindical de los trabajadores en la empresa (generalista y especializada) correlaciona positivamente con el desarrollo de las principales dimensio…
The Contribution of Electrical Resistivity Measurements to the Analysis of Landslide Events
2005
In order to gain insight into the study of natural avalanches dynamics, we illustrate a statistical model based on a dissipative dynamical variable associated to a position dependent factor of safety field. This model, as experimentally demonstrated, is able to reproduce the complex structure of landslide events, such as power-law distributions. In this paper, we introduce an explicit dependence of the safety factor on the electrical resistivity to simulate landslide events in pyroclastic soils. An application of the model to data acquired in a test area characterized by flowslide events (Monte Albino, Campania Region - South Italy) bear witness the relevant role played by the resistivity m…
Stability of Embankments Resting on Foundation Soils with A Weak Layer
2021
The presence of weak layers in geotechnical systems, including soil or rock masses, both natural and man-made, is more frequent than is normally believed. Weak layers can affect both failure mechanisms, in drained and in undrained conditions, as well as in static and seismic conditions, and the safety factor. In the present study, conducted numerically using the finite-element method (FEM) Plaxis 2D code, the influence of a horizontal thin weak layer on stress and strain distribution, on failure mechanisms and on the overall stability of an embankment was evaluated. The results obtained prove that when the weak layer is located at a significant depth from the foundation plane, the failure m…
Compliance, adherence, concordance, medical recollination - czyli jak poprawić efektywność i bezpieczeństwo leczenia stomatologicznego
2019
Bezpieczeństwo farmakoterapii jest ważne dla wszystkich specjalistów zaangażowanych w proces leczenia chorych. W związku z tym, iż znaczna część pacjentów cierpi z powodu wielu dolegliwości, musi stosować jednocześnie kilka leków. Może to prowadzić do błędów terapeutycznych, które często są przyczyną powikłań i niezamierzonych szkód. Polipragmazja wymusza więc skrupulatne prowadzenie kartoteki pacjenta oraz dokładne zbierania danych klinicznych. Kluczowa w tym procesie jest odpowiednia współpraca lekarza z pacjentem, ponieważ determinuje ona zarówno krótko-, jak i długoterminowe wyniki prowadzonej terapii. Bezpieczne i skuteczne leczenie dentystyczne również wymaga dokładnego wywiadu lekars…
Un estudio piloto sobre el efecto diferencial de la fatiga por conducción en personas mayores
2011
Hay indicios de que la fatiga, uno de los principales efectos de la conducción prolongada, es más notable en mayores. El presente artículo recoge un estudio sobre el efecto de la conducción prolongada utilizando un simulador, en un grupo de sujetos mayores de 55 años. Los sujetos fueron evaluados médica y psicológicamente antes y después de la prueba de conducción. Se aplicaron las pruebas médicas de tensión arterial, pulso y saturación de oxígeno en sangre y como prueba psicológica, el Driver-Test. Resultados preliminares indican que existe una disminución del rendimiento después de conducir, afectando especialmente a la capacidad de toma de decisiones. Some evidences show that fatigue, th…
Evolution of Free Amino Acids, Histamine and Volatile Compounds in the Italian Anchovies (Engraulis encrasicolus L.) Sauce at Different Ripening Times
2022
In this study, the evolution of the safety, nutritional, and volatile profile of a traditional Italian anchovy sauce with protected designation of origin (PDO), called “colatura di alici di Cetara”, is investigated after 12, 24, and 48 months of aging in wooden barrels. Some physicochemical parameters, free amino acids, volatile compounds, and histamine contents were evaluated during the aging of the samples. Glutamate, which together with aspartate is responsible for the umami taste, was the predominant free amino acid in the tested fish sauce, with a significant increase during the 48 months of maturation. The total amino acid content of the anchovy sauce increased from 24 to …
