Il cibo degli dei

2019

L’articolo mette a raffronto le tavole di san Giuseppe salentine con quelle siciliane. In particolare si mostra la probabile origine ebraica delle tavole di san Giuseppe di Salemi per la presenza di elementi che ritroviamo nella festa di sukkot. L'article compare les tables de Saint Joseph dans le Salento avec celles de Sicile. En particulier, l'origine juive probable des tables de Saint Joseph de Salemi est montrée en raison de la présence d'éléments que l'on retrouve dans la fête de Souccot

Thermo-Mechanical Behaviour of Flax-Fibre Reinforced Epoxy Laminates for Industrial Applications

2015

The present work describes the experimental mechanical characterisation of a natural flax fibre reinforced epoxy polymer composite. A commercial plain woven quasi-unidirectional flax fabric with spun-twisted yarns is employed in particular, as well as unidirectional composite panels manufactured with three techniques: hand-lay-up, vacuum bagging and resin infusion. The stiffness and strength behaviours are investigated under both monotonic and low-cycle fatigue loadings. The analysed material has, in particular, shown a typical bilinear behaviour under pure traction, with a knee yield point occurring at a rather low stress value, after which the material tensile stiffness is significantly r…

Termoelektrisko īpašību pētījumi tetratiotetracēna atvasinājumu plānās kārtiņās

2018

Darbā tika izveidotas organisku pusvadītāju - tetratiotetracēna (TTT) atvasinājumu plānas kārtiņas, izmantojot termiskās iztvaicēšanas metodi vakuumā. Izmantotie atvasinājumi ir ar metil, ¬¬metoksi, fenil un izopropil grupu aizvietojumiem 2. un 8. tetratiotetracēna molekulas pozīcijā, dažādās kombinācijās. Tika pētīta plāno kārtiņu morfoloģija, izmantojot ar skenējošā elektronu mikroskopu iegūtos attēlus, kā arī termoelektriskās īpašības, nosakot to elektrisko vadītspēju un Zēbeka koeficientu. Plānās kārtiņas tika pētītas gan tīrā veidā kā arī dopētas ar jodu, iegūstot p-tipa pusvadītāja īpašības. Tika izveidots tetratiotetracēna plāno kārtiņu termoelektriskais ģenerators. Darbā ir veikti t…

Ar antimonu un alvu leģētu Bi2Se3 plānu kārtiņu un nanovadu sintēze un īpašības

2018

Pēdējos gados augusi interese par materiāliem ar topoloģiskā izolatora (TI) īpašībām. TI ir tilpumā nevadoši, bet to virsmai piemīt metāliskas īpašības. Lielākā daļa TI ir labi termoelektriski (TE) materiāli istabas temperatūrā. Lai panāktu to, ka virsmas vadītspēja ir dominējoša, vajadzīgs nomākt tilpuma vadītspēju, kas rodas no defektiem. Pirmkārt, tilpuma vadītspēju var samazināt, samazinot vismaz vienu no TI struktūras dimensijām līdz nanoizmēram, kas būtiski palielina virsmas – tilpuma attiecību, kā arī veicot materiāla vakanču kompensējošu leģēšanu. Leģēšana var tikt izmantota arī materiālu TE īpašību uzlabošanai, tā optimizējot lādiņnesēju koncentrāciju un saglabājot to kustīgumu. Da…

Formation structure of optimality by thermoeconomics: disassembling thermodynamic and external influences in energy systems’ design

2009

In this paper an original thermoeconomic approach for the optimization of complex energy systems is presented, based on a revitalized concept of “scope”, and therefore indicated as Scope Oriented Thermoeconomics (SOT). In plants including dissipative components, it allows to formulate non-arbitrary allocation criteria as concerns marginal costs; consequently, the optimization process is disassembled to recognize the Formation Structure of Optimality, i.e. the specific influences of thermodynamic and economic parameters in the path toward the optimal design. The method is applied to a very didascalic example, that is the optimization of the condensation temperature in a vapour compression ch…

A Quantitative Analysis of the Thermoelastic Effect in CFRP Composite Materials

2010

In this study the thermoelastic signal from carbon fibre-reinforced plastic (CFRP) laminates is investigated. A comparison between the theoretical and experimental values of the thermoelastic signal is reported, with the theoretical predictions obtained from two different quantitative models. These models are based on the classic thermoelastic effect law extended to the case of orthotropic materials (by using the mesomechanical or bulk approach), and the modified law assuming that the surface resin-rich layer behaves as a strain witness of the laminate. It is found that the theoretical predictions of the two models can be strongly and differently influenced by the intrinsic orthotropy of ca…
