Modeling of the sustainable development of multifunctional farms in Ukraine
2017
Dynamiczne optymalne planowanie i prognozowanie racjonalnego połączenia sektorów rolniczych pozwala przy najniższych kosztach i ryzyku dokonać przejścia od tradycyjnych form działalności do rolnictwa ekologicznego lub organicznego. Artykuł naświetla kwestię gradacji ekologiczności gospodarstwa rolnego, która obejmuje podstawowe kryteria zrównoważonych modeli rozwoju rolnictwa. Za pomocą programowania matematycznego udowodniono skuteczność zwiększenia poziomu ekologizacji. Przedstawiono zautomatyzowany model rozwoju gospodarstwa rolnego oraz sposoby zwiększenia bezpieczeństwa produkcji. Model jest uniwersalny i może być stosowany w przedsię-biorstwach lasostepu Ukrainy Lewobrzeżnej.
Modelli colturali sostenibili per le produzioni orto-floro-frutticole di qualità
2008
Il concetto di sviluppo sostenibile si è articolato nel tempo, integrando l’idea di sviluppo socialmente accettabile e compatibile con il mantenimento degli equilibri ecologici e la economicità dei processi produttivi. La salvaguardia dell’ambiente e della salute umana, l’uso razionale delle risorse naturali e degli input tecnici, il mantenimento di elevati e stabili livelli economici di crescita ed il rispetto dei principi di equità sociale, sono i paradigmi della sostenibilità dei processi produttivi, anche in agricoltura. In un contesto di economia globalizzata, che di fatto ha creato le condizioni di estremo disagio delle economie agricole più deboli e che comunque ha reso più aleatorie…
Proton Exchange Membrane Fuel Cells (PEMFCs): Advances and Challenges
2021
The study of the electrochemical catalyst conversion of renewable electricity and carbon oxides into chemical fuels attracts a great deal of attention by different researchers. The main role of this process is in mitigating the worldwide energy crisis through a closed technological carbon cycle, where chemical fuels, such as hydrogen, are stored and reconverted to electricity via electrochemical reaction processes in fuel cells. The scientific community focuses its efforts on the development of high-performance polymeric membranes together with nanomaterials with high catalytic activity and stability in order to reduce the platinum group metal applied as a cathode to build stacks of proton …
An empirical assessment of employer branding as a form of sport event sponsorship
2019
Purpose. The purpose of this paper is to expand and test Backhaus and Tikoo’s (2004) employer branding (EB) conceptual framework from the perspective of internal EB in a sport event sponsorship context. Design/methodology/approach. This study developed a set of hypotheses, which were tested in the context of a business-to-business multinational organization’s sport event sponsorship project. Empirical data were collected from 716 employees of the case company after the sponsorship project was complete. Findings. The results support all the hypotheses and reveal that a sport event sponsorship project can act as a means to achieving EB goals in the investigated context. Research limitations/i…
A novel intrinsically disordered outer membrane lipoprotein ofAggregatibacter actinomycetemcomitansbinds various cytokines and plays a role in biofil…
2017
Intrinsically disordered proteins (IDPs) do not have a well-defined and stable 3-dimensional fold. Some IDPs can function as either transient or permanent binders of other proteins and may interact with an array of ligands by adopting different conformations. A novel outer membrane lipoprotein, bacterial interleukin receptor I (BilRI) of the opportunistic oral pathogen Aggregatibacter actinomycetemcomitans binds a key gatekeeper proinflammatory cytokine interleukin (IL)-1b. Because the amino acid sequence of the novel lipoprotein resembles that of fibrinogen binder A of Haemophilus ducreyi, BilRI could have the potential to bind other proteins, such as host matrix proteins. However, from th…
Expression of p63, p53 and ki-67 in patients with cervical intraepithelial neoplasia
2017
Objective: Cervical intraepithelial neoplasia (CIN) is a dysplastic process in cervical squamous epithelium and carries a risk of progression to cervical cancer. The aim of this study was to compare expression of three biomarkers named p53, p63 and Ki-67 in patients with various grades of cervical intraepithelial neoplasia and in a control group. Material and Method: 58 patients were enrolled in the study. Each patient underwent a colposcopy-guided biopsy of the cervix. Immunostaining for markers (p53, p63 and Ki-67) was performed on tissue samples of normal cases (n=10), CIN I (n=20), CIN II (n=14), and CIN III (n=14). Results: Our study showed a significant increase of the expression of t…
Endoderm development requires centrioles to restrain p53-mediated apoptosis in the absence of ERK activity
2021
Centrioles comprise the heart of centrosomes, microtubule-organizing centers. To study the function of centrioles in lung and gut development, we genetically disrupted centrioles throughout the mouse endoderm. Surprisingly, removing centrioles from the endoderm did not disrupt intestinal growth or development but blocked lung branching. In the lung, acentriolar SOX2-expressing airway epithelial cells apoptosed. Loss of centrioles activated p53, and removing p53 restored survival of SOX2-expressing cells, lung branching, and mouse viability. To investigate how endodermal p53 activation specifically killed acentriolar SOX2-expressing cells, we assessed ERK, a prosurvival cue. ERK was active t…
Food Packaging. Narrazioni semiotiche e branding alimentare
2022
Analysing food packaging means discovering its narratives, the ways in which a culture thinks about it. To analyze how brands speak to consumers through packaging is to delineate the type of consumers that brand is targeting. Packaging is one of the elements of the branding process and is also one of the texts through which a certain culture thinks about and reflects food, dietetics, health, taste, and nutrition.
Che cos'è il packaging
2014
Racchiudere e proteggere, descrivere e raccontare, coinvolgere e consigliare. Da semplici imballaggi, le confezioni dei prodotti si sono via via trasformate in oggetti di senso complessi, in grado di rispondere a molteplici esigenze comunicative, di marketing, logistiche e igieniche. Entrano nelle nostre case, riempiono gli spazi domestici, diventano molto spesso oggetti d'uso quotidiano. Ma che ne è del prodotto contenuto? Il volume illustra il modo in cui il pack lo racconta, lo valorizza, lo traduce, proponendosi come un'unità semiotica sempre nuova. rivolto a studenti di design e comunicazione, professionisti del branding, designer ed esperti di marketing, il testo offre una visione com…
Ethyl hexanoate transfer in paper and plastic food packaging by sorption and permeation experiments
2008
The barrier properties of one treated paper packaging and one standard plastic film (bi-oriented polypropylene, biOPP) were assessed for ethyl hexanoate. Three methods based either on sorption (gravimetry and micro-atmosphere-derived method) or permeation kinetic determination were used in controlled conditions of aroma vapor concentration (107 Pa), temperature (25 degrees C) and relative humidity (about 0 %). Ethyl hexanoate solubility values were on the same range of magnitude for both packaging films in spite of their different nature and composition. Ethyl hexanoate affinity for both films was well predicted by their respective solubility parameters. Solubility values were different acc…
