On a stochastic disease model with vaccination
2006
We propose a stochastic disease model where vaccination is included and such that the immunity isn’t permanent. The existence, uniqueness and positivity of the solution and the stability of disease free equilibrium is studied. The numerical simulation is done.

Impact des invertébrés sur les fonctions des sols et leurs applications dans les systèmes sol-plante
2017
EABIOMEAGROSUP; De par leur structure tridimensionnelle, leur large gamme de porosité, la diversité de leurs caractéristiques physicochimiques et des conditions microclimatiques, les sols abritent un nombre considérable, parfois inestimable d'organismes. Au sein des agroécosystèmes, les enjeux sont de comprendre les relations entre la plante cultivée et son environnement biophysique incluant les interactions biologiques et les effets de la biodiversité des organismes des sols. L’impact de la faune du sol sur la production primaire peut être vu au travers de leur effet sur les fonctions de (i) recyclage des nutriments, (ii) entretien de la stabilité/structure du sol, (iii) contrôle des bioag…

Biogaz - potencjalne źródło energii
2018
W artykule zaprezentowano właściwości biogazu oraz sposób jego produkcji wraz ze szczegółową charakretystyką wybranych substratów wykorzystywanych do jego wytwarzania. Przedstawiono również technologie produkcji biogazu: mokrą oraz suchą z uwzględnieniem ich najważniejszych wad i zalet. Scharakteryzowano aspekty społeczne, środowiskowe i ekonomiczne, które należy brać pod uwagę podczas planowania budowy biogazowni oraz przeanalizowano obecny rynek biogazowy w Polsce.
Characterisation of NO synthases from the alga Klebsormidium nitens
2022
Nitric oxide (NO) is an important cellular signaling molecule regulating various physiological processes, in both animals and plants. In animals, NO synthesis is mainly catalyzed by NO synthase (NOS) enzymes. In plants, NOS-like activities sensitive to mammalian NOS inhibitors have been measured, although no sequences encoding mammalian NOS have been found in land plants. Interestingly, we identified NOS-like sequences in about twenty algae species. These latter include the filamentous Charophyta green algae Klebsormidium nitens, a biological model to study the early transition step from aquatic algae to land plants. Currently, two NOS were identified in K. nitens genome: i) KnNOS1 which po…
Studies concerning the production of volatile oil, rhizomes and roots, to different genotypes of Valeriana officinalis L.
2010
Valeriana officinalis L. is considered to pertain to European species, with great ecologic plasticity, which allows its adaptation to climate conditions characteristics to plain areas and also to mountain areas up to an altitude of 2400 meters. The species is a well-known curative plant, with a long history and multiple uses. Essential oils deriving from this species revealed the interest of researchers in food industry, cosmetics and officinal industry, furthermore being used as additives too.The raw material from which essential oils are being extracted is represented mainly by rhizomes and roots. This study has the purpose to emphasize the differences of essential oils production registe…
Tiempos felices: Transformaciones en las tecnologías psicológicas de gobierno de la subjetividad
2020
This paper traces some inflections in the psy disciplines? discourses and technologies for the government of subjectivity during the last decades. It is focused on exploring different mechanisms through which psychological disciplines ?their discourses, techniques and practices? penetrate social life and contribute to establishing subject models consistent with transformations in the political and economic rationalities of late capitalism. Drawing on previous research in the field of gender politics and happiness discourses in the pop psychological culture, I track a line with three moments: i) the production of psychological individuality and identity normalization; ii) the proliferation o…
AN AGENT BASED ARCHITECTURE FOR MANUFACTURING E-MARKETPLACES
2005
This chapter presents the Agent Based Architecture developed within the research project, titled "Process and Production Planning in manufacturing Enterprise Networks". As mentioned in Chapter 1, the architecture has been developed to support “added value services” in neutral linear e-marketplaces, i.e. in virtual districts. In this chapter the architecture will be described from a functional and dynamic point of view by using the formalisms used in the project. In particular, from a functional perspective, the architecture is described by using the IDEF0 formalism, while its dynamics are specified by UML activity diagrams.
Food safety risk analysis from the producers' perspective: prioritisation of production process stages by HACCP and TOPSIS
2018
[EN] From the manufacturers perspective, the Hazard Analysis and Critical Control Point (HACCP) system nowadays represents the mainly way to implement the food safety risk management in food industries. Nevertheless, the identification and prioritization of hazards as the outcome of the first principle of HACCP is not sufficient to identify production process stages that more significantly and critically contribute to the consumer¿s risks. With this recognition, the present paper proposes a Quantitative Risk Assessment (QRA) approach based on HACCP and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) to individuate production process phases on which implementing co…
