The Relationships Between Customer Brand Engagement in Social Media and Share of Wallet

2016

This chapter investigates the motivational drivers of customer brand engagement in social media and examines the nature of the relationships between these drivers and engagement, as well as the relationships between brand engagement and share-of-wallet. In addition, we tested the moderating effect of the frequency of social media visits on the relationship between engagement and share-of-wallet. The hypothesized relationships were analyzed using an online survey of 818 members of one Facebook brand community. The results suggested that community exerts the strongest positive effect on customer brand engagement and that customer brand engagement positively influences SOW. The findings also i…

Degradation of stone materials in the archaeological context of the Greek-Roman Theatre in Taormina (Sicily, Italy)

2010

In the present work results on the degradation phenomena of stone materials in the Ancient Theatre of Taormina, one of the most important Greek–Roman monuments of Sicily, are reported. Artificial stone materials in different conservation conditions were investigated. Samples of salt efflorescences from brick walls and degraded setting mortars were taken from the open gallery in “summa cavea”. The chemical, physical and structural characterization was performed by means of X-Ray Photoelectron Spectroscopy (XPS), X-Ray Diffraction (XRD) and X-Ray Fluorescence (XRF), both in situ and ex situ. Results showed that the deterioration of stone materials is due to the aggressive action of the enviro…

Computational Modeling of Ascending Thoracic Aortic Aneurysm and Dissection

Experimental conditions for respiration and growth studies of F0 and F1 larval and juvenile European seabass Dicentrarchus labrax

2022

Water parameters in the 2 years before spawning of F0 (08.02.2016-06.03.2018) and during larval and juvenile phase of F1: Larval period until 17.05.2018 (48 dph, 900 dd) and 01.06.2018 (63 dph, ~900 dd) for warm and cold life condition respectively, for the juveniles until 28.09.2018 (180 dph, ~4000 dd) and 12.02.2019 (319 dph, ~5100 dd) for warm and cold conditioned fish respectively. Means ± s.e. over all replicate tanks per condition. Temperature (Temp.), pH (free scale), salinity, oxygen and total alkalinity (TA) were measured weekly in F1 and monthly in F0; sea water (SW) measurements were conducted in 2017 and 2018. Water parameters during larval and early juvenile phase of F0: Larval…

The sarculator stratified prognosis of patients with high-risk soft tissue sarcomas (STS) of extremities and trunk wall treated with perioperative ch…

2017

11016 Background: Patients with extremity and trunk wall STS with high malignancy grade and size larger than 5cm are considered at high risk of death, but in fact this risk varies broadly depending on histologic subtype and size. The Sarculator, a nomogram for STS, can improve prognostic assessment of these patients. This tool was evaluated for stratifying risk of distant metastasis (DM) and overall survival (OS) in a RCT investigating perioperative chemotherapy. Methods: High-risk STS patients were randomly assigned to receive either three cycles of preoperative chemotherapy with epirubicin (120 mg/m2) and ifosfamide (9 g/m2) or the same three preoperative cycles followed by two further p…

Drying enhances immunoactivity of spent brewer's yeast cell wall β-D-glucans.

2015

Due to immunological activity, microbial cell wall polysaccharides are defined as 'biological response modifiers' (BRM). Cell walls of spent brewer's yeast also have some BRM activity. However, up to date there is no consensus on the use of spent brewer's yeast D-glucan as specific BRM in humans or animals. The aim of this paper is to demonstrate the potential of spent brewer's yeast β-D-glucans as BRM, and drying as an efficient pretreatment to increase β-D-glucan's immunogenic activity. Our results revealed that drying does not change spent brewer's yeast biomass carbohydrate content as well as the chemical structure of purified β-D-glucan. However, drying increased purified β-D-glucan TN…

La Casina cinese alla Favorita di Palermo: un'ipotesi di lettura.

2016

L'articolo verte su un'ipotesi interpretativa della componente decorativa della Casina cinese alla Favorita di Palermo basata sulla componente "alla cinese" e su una sua densa natura confuciana. The paper offers a hypothesis of interpretation of the decorative patterns of the Casina cinese at the Favorita Park in Palermo which is based on the component "in Chinese style" that is characterized by a strong Confucian element.

ORGANIC-INORGANIC HYBRID CATALYSTS BASED ON IMIDAZOLIUM AND THIAZOLIUM SALTS

In the last years, great attention was focused on immobilized ionic liquids for their application in the field of catalysis. The main challenge is represented by the possibility of combining the benefits of the ionic liquids to that of the supports. In order to achieve this ambitious objective both the choice of the support and the functionalization strategy are of fundamental importance. In this context, one of the aims of this doctoral project was to develop novel catalysts based on covalently mono- or multilayer imidazolium or thiazolium networks onto a high ordered mesoporous silica or carbon nanotubes materials. The second goal of this PhD thesis was to design novel imidazolium based c…

Transglutaminase activity is involved in Saccharomyces cerevisiae wall construction

2002

Transglutaminase activity, which forms the interpeptidic cross-link N(epsilon)-(gamma-glutamyl)-lysine, was demonstrated in cell-free extracts of Saccharomyces cerevisiae by incorporation of [(14)C]lysine into an exogenous acceptor, N,N'-dimethylcasein. Higher levels of the activity were present in the cell wall, which also contained endogenous acceptors. The enzyme activity in the wall was inhibited by cystamine, a known inhibitor of transglutaminase, and by EDTA, indicating a cation-dependent activity. After the endogenous wall acceptors were labelled radioactively by transglutaminase, extraction with SDS solubilized about 50% of the total radioactivity, while Zymolyase and chitinase each…

Isolation and culture of grape vine cv. Chardonnay leaf protoplasts

1990

Experimental conditions were established that resulted in high yields and good viability of the protoplasts obtained from leaves of Vitis vinifera, cv. Chardonnay regenerated in vitro by somatic embryogenesis. The effect of factors of the culture medium and various environmental conditions upon the frequency of cell division has been examined, and a method of culture is described by which protoplasts were induced to begin division. Most protoplasts obtained in this way regenerated cell walls within the first few days and cell division occurred after 10 days of culture in a liquid medium. Some cells have divided two or even three times. Nevertheless, the cells did not continue dividing beyon…
