Financial Crises and the Composition of Cross-Border Lending
We examine the composition and drivers of cross-border bank lending between 1995 and 2012, distinguishing between syndicated and non-syndicated loans. We show that on-balance sheet syndicated loan exposures, which account for almost one third of total cross-border loan exposures, increased during the global financial crisis due to large drawdowns on credit lines extended before the crisis. Our empirical analysis of the drivers of cross-border loan
Read moreA data porting tool for coupling models with different discretization needs
The presented work is part of a larger research program dealing with developing tools for coupling biogeochemical models in contaminated landscapes. The specific objective of this article is to provide researchers with a data porting tool to build hexagonal raster using information from a rectangular raster data (e.g. GIS format). This tool involves a computational algorithm and an open source software (written in C). The method of extending the

This cytohistopathological study was performed to have a better knowledge of the continuum of cellular events, from mesenchymal stem cells to mature cordocytic phenotypes with their morphological heterogeneity and multiple functions in the human skin. We used light microscopy, as well as transmission and scanning electron microscopy to study multiple tissue fragments obtained by skin biopsy from post-burn tissue, surrounding superficial temporal
Read moreEconomic analysis of nature preservation investments: the zonal travel cost approach applied for Harghita County of Romania
The paper is focused on the cost of travel method and specific issues involved by the use of this method for monetization of benefits provided by nature preservation investment projects. Usually, nature preservation investment projects are non revenue generator projects and consequently the monetization of benefits provided is essential in the process of analysis and valuation of these projects, because benefits are the only positive effects able

The present work reports the influence of the loading mode provided during training under constant stress, in bending, applied to lamellar specimens of Cu-Zn-Al shape memory alloys (SMAs). During training, the specimens were bent by a load fastened at their free end, while being martensitic at room temperature and they lifted the load by one-way effect (1WE), during heating up to austenitic field. On cooling to martensite field, the lower concave

This paper introduces an adapted high-speed high pressure torsion (HS-HPT) method of severe plastic deformation applied for obtaining shape memory alloy (SMA) active elements with revolution symmetry, able to develop axial displacement/force. Billets with circular crown forms were cut from Fe-28Mn-6Si-5Cr (mass%) SMA ingots and, by means of HS-HPT technology, were directly turned into modules, with truncated cone shell configurations. This process

In this work, the aim was to investigate how the deformation by cold rolling affects the microstructure and transformation temperatures of Fe-14Mn-6Si-9Cr-5Ni alloy prepared by powder metallurgy route. The characteristic of the martensitic transformation in the given alloy composition was investigated in terms of the amount of deformation via cold rolling. Mechanical alloying was applied for reaching better chemical homogenization level in powder

The present paper aims to identify a sequence of bulk-deformation processes able to produce sufficient quantities of ultra fine grained (UFG) volume as to be of interest for practical purposes. Samples of aluminum Al 1100alloy (98.41 % Al) were subjected to repetitive equal channel angular pressing (ECAP) at room temperature, up to in eight passes. Severely plastic deformed (SPD) specimens were cold rolled in thin strips which were subjected to structural
Read moreHistoricising Interpolations in the Isaiah-Memoir
In studies on the composition of prophetic literature, the larger textual layers reinterpreting earlier texts, the so-called Fortschreibungen, received much attention. It is well-known that beside these larger literary elaborations prophetic books also contain shorter explanatory interpolations, often called glosses, which intend to clarify a particular imagery of the prophecy (e.g., Isa 9:14). A systematic reading of these short annotations has
