Il saggio ripercorre la storia bancaria e industriale del periodo che precede la nascita dell'IR
Note ai discorsi
Nelle note viene ricostruito il contesto in cui i discorsi di Agnelli furono pronunciati, rendendo ragione della storia e dell'importanza dei vari organismi nazionali ed internazionali coinvolti. Si tracciano inoltre, per grandi linee, gli avvenimenti cui i discorsi si riferiscono
Successful removal of a guidewire from the jugular vein of a mature horse
This case report describes the removal of a metal
guidewire that was lost accidentally in the jugular vein
during the placement of an indwelling catheter. The
proximal end of the guidewire was identified in the distal
third of the cervical region by radiography and
ultrasonography. The retained wire was removed
successfully by percutaneous fluoroscopically assisted
endovascular retrieval with a 4 pronged retrieval catheter
Rapid and noninvasive quality control of anhydrous milk fat by PTR-MS: The effect of storage time and packaging
In this study, proton transfer reaction-mass spectrometry (PTR-MS), coupled with a time-of-flight mass analyzer and a multipurpose automatic sampler, was evaluated as a rapid and nondestructive tool for the quality control of anhydrous milk fat. Anhydrous milk fats packed in cardboard and bag-in-box were compared during refrigerated shelf life at 4°C for 9 months. Anhydrous milk fat samples were taken at 120, 180, and 240 days and measured by PTR-MS during storage at 50°C for 11 days. Univariate and multivariate data analysis were performed in order to classify samples according to the packaging type and compare aromatic profiles. Markers related to both packaging and storage duration were identified, and all stored samples were clearly distinguishable from reference fresh samples. Significant differences in some key butter aroma compounds such as 2-pentanone, 2-heptanone, 2/3-methylbutanal, acetoin, and butanoic acid were observed between different types of packaging. During the refrigerated storage, differences related to packaging are more evident, while during the storage at 50°C, the fat oxidation induced by the high temperature becomes the most relevant phenomenon independently of the packaging type. These results indicate the importance of avoiding anhydrous milk fat storage at 50°C for long times during industrial production processes. All together data demonstrated the viability of PTR-MS as a rapid and high-sensitivity tool in agroindustry quality control progra
The good, the bad and the aged: predicting sensory quality of anhydrous milk fat by PTR/SRI-Tof-MS analysis and data mining
Due to its versatility, anhydrous milk fat (AMF) has become more popular as a food industry ingredient,but its quality control remains a critical challenge. A direct injection mass spectrometry technique wasapplied to predict sensory quality of AMF. Volatilome analysis through proton transfer reaction massspectrometry (PTR-MS) was used to classify 39 industrial samples of AMF according to industrial sensoryevaluation and to accelerated ageing. A selective reagent ion system was used to evaluate the suitabilityof PTR-MS alternative ionisation modes for quality control. Supervised multivariate data analysis suc-cessfully classified samples and showed that samples exposed to accelerated shelf life at 50C presentedhigher intensities of most volatiles, especially for the ones derived from oxidation like aldehydes andketones, while samples with an acceptable quality level had lower emissions of volatiles. PTR-MStechnique is ideal to support agroindustry sensory quality programs requiring rapid on-line analytical informatio

Size, Structure, and Strategies: Insolvency and "The Nature of the Firm" in Italy, 1920S-1970S
During the Twentieth century, Italian joint-stock companies remained relatively small and tended to die young. This fact constrained the development of the full potential of the Italian industry, as small-dimensioned companies struggled to implement the most efficient technologies and managerial techniques. This paper analyses this problem by looking at the functioning of insolvency procedures. Using quantitative and qualitative evidence, we show how various devices that progressively appeared on the scene failed in providing efficient solutions to re-start worthy companies. Insolvency procedures thus remained liquidation-prone, a factor that contributes to explain the peculiarity and the limits of Italian industrial capitalism.
