Sapropeļa kūdras, sapropeļa kokskaidu siltumizolācijas plāksnes un to īpašības

2014

Siltumizolācijas materiāli, kuros par pildvielu tiktu izmantoti vietējie biomasas produkti, bet par saistvielu kalpotu dabiskas izcelsmes saistvielas, piemēram, sapropelis, uzskatāmi par inovatīviem un to pielietošana sekmētu ekoloģiskās būvniecības nozares attīstību. Šādu risinājumu izstrāde ir aktuāla, jo Latvijā ir ievērojami sapropeļa resursi, kuru izmantošanu kavē to nepietiekama izpēte un ekoloģiskās būvniecības nozares intensīva attīstība. Pētījuma mērķis ir iegūt sapropeļa-koksnes, kūdras-koksnes siltumizolācijas plāksnes, noteikt optimālās plātnes sastāva attiecības un raksturot iegūto plātņu īpašības. Veikto pētījumu rezultātā tika noteiktas siltumizolācijas materiālu paraugu mehā…

SECOND LIFE OF RURAL AND ORDINARY - Ricostruzione delle case Di Stefano - Gibellina Nuova

Il progetto affronta il problema degli insediamenti danneggiati dal terremoto. Nel caso specifico si tratta di un “baglio”: in origine una fattoria fortificata per resistere agli attacchi della pirateria; in seguito centro di controllo dei feudi. Il baglio in questione è noto come Case Di Stefano, dal nome degli ultimi proprietari. Il Comune di Gibellina se lo ritrova come unica preesistenza nel sito concessogli dopo il terremoto del 1968 per rifondazione della città e decide di recuperalo ipotizzando, a quel tempo, una generica destinazione a centro culturale. A partire dagli elementi del rilievo e dalla descrizione a memoria degli ultimi proprietari, si pensò a una ricostruzione che mante…

Drivers of CO2 emissions in the former Soviet Union: A country level IPAT analysis from 1990 to 2010

2013

There are a small number of countries that have managed to decrease emissions over the last two decades e most of them emerged from the FSU (former Soviet Union ). CO2 emissions for these countries combined have decreased by 35% between 1990 and 2010, while global emissions increased by 44%. Most studies investigate the FSU as a single block ignoring the significant and persistent diversity among countries in the region. This study is the first providing detailed country by country analyses determining factors for changes in post-Soviet republics by applying a disaggregated version of the commonly used (IPAT) index decomposition analysis including energy intensity, affluence industrializati…

Experiences of perinatal women and public healthcare providers in a community affected by the great east Japan earthquake and tsunami: Concerns that …

2020

Abstract Particular support needs of perinatal women in a disaster have been difficult to grasp through preexisting quantitative epidemiological studies. This study aimed to extract concerns that must be considered for perinatal women's mental healthcare in postdisaster settings based on lessons from the Great East Japan Earthquake. Narrative messages regarding protective and risk factors for mothers' mental health from a representative population of mothers who had given birth and all official maternal caregivers, in a coastal town devastated by the catastrophe were subjected to qualitative analyses. Eight concerns were extracted as specific support needs: (1) improve information pathways,…

Generalized curved beam on elastic foundation solved by Transfer Matrix Method

2011

A solution of space curved bars with generalized Winkler soil found by means of Transfer Matrix Method is presented. Distributed, concentrated loads and imposed strains are applied to the beam as well as rigid or elastic boundaries are considered at the ends. The proposed approach gives the analytical and numerical exact solution for circular beams and rings, loaded in the plane or perpendicular to it. A well-approximated solution can be found for general space curved bars with complex geometry. Elastic foundation is characterized by six parameters of stiffness in different directions: three for rectilinear springs and three for rotational springs. The beam has axial, shear, bending and tor…

Bounds on plastic strains for elastic plastic structures in plastic shakedown conditions

2007

The problem related to the computation of bounds on plastic deformations for structures in plastic shakedown condition (alternating plasticity) is studied. In particular, reference is made to structures discretized by finite elements constituted by elastic perfectly plastic material and subjected to a special combination of fixed and cyclic loads. The load history is known during the steady-state phase, but it is unknown during the previous transient phase; so, as a consequence, it is not possible to know the complete elastic plastic structural response. The interest is therefore focused on the computation of bounds on suitable measures of the plastic strain which characterizes just the fir…

Determination of absolute internal conversion coefficients using the SAGE spectrometer

2016

A non-reference based method to determine internal conversion coefficients using the SAGE spectrometer is carried out for transitions in the nuclei of 154Sm, 152Sm and 166Yb. The Normalised-Peak-to-Gamma method is in general an efficient tool to extract internal conversion coefficients. However, in many cases the required well-known reference transitions are not available. The data analysis steps required to determine absolute internal conversion coefficients with the SAGE spectrometer are presented. In addition, several background suppression methods are introduced and an example of how ancillary detectors can be used to select specific reaction products is given. The results obtained for …

A Top-Down Approach Based on the Circularity Potential to Increase the Use of Reclaimed Asphalt

2023

Resource depletion and climate change, amongst others, are increasingly worrying environmental challenges for which the road engineering sector is a major contributor. Globally, viable solutions that comply with the principles of circular economy (CE) are being investigated that can replace conventional asphalt mixtures in a post-fossil fuel society. The use of reclaimed asphalt (RA) is a widely used and well-established method to reduce the environmental and economic impacts of asphalt mixtures while increasing their circularity. However, RA’s market supply and demand have not yet been systematically analyzed and established. Moreover, the actual circularity potential and the opportu…
