At the end of the 18th century this method was confirmed ethnographically. Archaeological research has demonstrated that there is evidence for this process as early as 6050 BC. Analysis of the salts produced following an archeological experiment demonstrated that this was, in fact, a matter of obtaining the first food supplement in the history of the world.
High printing quality of banknotes and the variety of security features implemented in banknotes ... more High printing quality of banknotes and the variety of security features implemented in banknotes make a big difference between the genuine notes and high-quality forgeries. The counterfeiter cannot reproduce or imitate the printing quality and all security features embedded in every banknote, such as Optically Variable Ink, Optically Variable Diffractive Images, or intaglio printing. The present research focused on the examination of optically variable devices embedded on 50Îbanknotes. The altered banknotes were examined using different techniques.

Most of the metal and ceramic artefacts considered for this study originate from archaeological sites from the region of Moldavia and Dobrudja, and those of polychrome wood from state or private collections and monastic establishments. The data obtained, using modern experimental methods and techniques, has allowed us to set the fundaments of phenomenological aspects related to the conception/execution, acquired patina, evolutive effects of deterioration and degradation, historical contexts, etc. These discoveries have been acknowledged as interdisciplinary effects, as evidenced by the citations listed in scientometric databases.

For this purpose, the computer analyzed the composition of the tab, which is usually through various kinds counterfeit. By taking very small fragments of these pages, we can get useful information about the methods and techniques used by counterfeiters. The comparative analysis highlights the forgeries and certain connections with the original document. Therefore, there were obtained some data on their scientific investigation and highlighted the method used by forgeries.

The analytical methods used in the study for assessing archaeometric characteristics of some component materials, along with the white degree and glycolysis rate measurements of the label that allowed an extensive evaluation of the violin, were OM, SEM–EDX, and micro-FTIR. The preparation binder (egg white from thin gypsum layers) and the varnish (identification of linseed oil and colophony components, alongside contamination impurities) were assessed in order to evaluate the artefact conservation state, as well as the restoration and counterfeiting interventions. We can conclude that the violin was done by a violin maker from the Stradivari family, and it is a replica of the violins of that period.

The painting is made with oil colors on pressed cardboard, with preparation based on chalk powder and animal glue. The painting presents two elements as being counterfeit, which have attracted suspicions, namely the signature of the author (presenting a semi-transparent covering veil), and, on the back, a writing of dating, performed by a very controversial art historian. The investigation was carried out by direct analysis with magnification devices, in reflected UV (ultraviolet), VIS (visible), and NIR (near- infrared) light, and by OM, SEM-EDX, and μ-FTIR. The results showed that the painting is authentic and belongs to Nicolae Grigorescu, and the dating established previously by Amel...

The authors take into consideration archaeological discoveries and ethnographical surveys, correlated with known facts from the literature in the field. A special focus is on the presence of archaeological sites next to salt water springs, where specific objects were noted that are
used in the extraction, storage, manipulation and use of salt waters. Nevertheless, what distinguishes the Romanian region under discussion from similar regions of Europe is the intense, unexpected continuity in the use of a traditional, non-industrial water supply from salt water springs. Among the uses of salt water and halite in the area, we will mention numerous traditional halotherapeutic practices. The concordances shown between ancient and current traditional halotherapeutic practices in eastern Romania infer the existence of a strong halotherapeutic element in prehistory.
This aspect is generally neglected by archaeologists who deal with the evolution of human communities in an area rich in salt. The ancient and current halotherapeutic practices in eastern Romania are proof of an authentic ethnoscience acquired by human communities with salt outcrops and salt water springs. The analysis of these practices demonstrates their scientific validity from the current biochemical and
biophysical standpoint. The scientific explanation of the various effects of salt upon the human body is, in fact, given by the influence of NaCl aerosols and nanodispersions. Parts of these practices are being adopted by a series of recent halotherapeutic procedures, with reliable scientific and technological bases.

The approach was based on the existing archaeological data – description of briquetage sherds and their discovery contexts, as well as on ethnoarchaeological accounts and previous experimentations. The experiments allowed some valuable observations on the distinct aspects of this chaîne opératoire: modelling and firing the briquetage vessels; exposure to fire of the recipients filled with brine or a salt slurry of varied concentrations; the amount of time needed for crystallization and hardening of the salt, dependent on the fuels used and temperatures reached; ways of extracting the salt cakes from the ceramic coat; assessment of the effort (i.e. labour and raw materials) involved by the whole process. All the failures, challenges and eventual successes encountered during the experiments granted an insight into an ancient technique, described mainly a priori in the archaeological literature. Also, it gives a hint in understanding the appreciable importance and value of salt in times when this essential mineral was not available as it is today.

Accidental ethanol and carbon monoxide intoxications produce the most frequent causes of violent deaths among civilians in Romania. To provide an insight in these types of deaths and to bring attention upon the clinical and biological manifestations as well as of the typical morphologically findings, the authors present a strange case of fatal intoxication due to carbon monoxide in an 88 years old male, found in his bed. Moreover, because of the simultaneous death of the male�s wife in the attic of the house, with ethanol intoxication, we would also like to bring attention to the juridical notion of commorientes, since in the establishing of its constituting characteristics the forensic expertise plays a decisive role.

The surface structures and those from the interface of the corrosion layer with the metal core of the basic alloy were analyzed, in order to elucidate the nature of the materials used and the manufacturing processes. The analyzes by optical microscopy (OM) and electron microscopy (SEM), coupled with X-ray spectrometry (EDX), revealed the type of their degradation during the depositional period, as a result of the processes of chemical alteration and physical damage. A series of metallurgical techniques used were also established, as well as the identification of some finishing and decoration processes that led to the establishment of the objects’ functionality.

Horizontal mobility of heavy metals in soil was performed by the Kruskal-Wallis test which was used to evaluate the heavy metals concentrations according to the upstream downstream disposition of soil sample sites. Then the Mann-Whitney test was applied to find if variances between upgradient and downgradient parameters concentrations in the soil sample sites were homogenous. The results show that the soil is rich in organic matter (organic carbon and organic nitrogen) with a basic pH (7.94 <pH <8.7), characteristic of the landfill leachate. Metals such as lead (Pb) and zinc (Zn) are retained by the organic matter while the other metals (Cd, Cr, Cu, Fe) relative to migrate upstream to downstream. Thus, the flow of infiltration water into the soil...

The present paper reveals a way protecting the environment while producing high quality concrete. What make this type of concrete environmentally friendly are the recycled aggregates in the concrete composition amongst with eliminating the ecological impact by saving large amounts of natural aggregates resources. Recycling concrete comes with many other advantages that lead to waste reduction, economy in waste transportation and storage taxes, which are becoming increasingly expensive. This research is based on mix design and experimental tests carried out on C20/25 strength class concrete with uncontaminated leftover concrete aggregates (LCAgg). It reveals favorable results in order to militate for recycled concrete aggregate uses in regular concrete strength classes respectively for common structural elements, mainly for slabs. River sand (0/4 mm) and coarse aggregates (4/8 mm and 8/16 mm): natu...

This paper aims to present the current conservation status of some old ecclesiastical buildings of Iasi, a city which represents an ancient religious, cultural, academic and economic urban centre of Romania, correlated to the traces of the human life (socio-cultural and economic) and community attitude towards ecclesiastical heritage. For this purpose, the studies have been conducted on the local monuments using GIS technologies for a better understanding and valorisation of the cultural heritage in an integrated manner. First we created a spatial database of ecclesiastical heritage included into the most recent national list of cultural heritage, in 2015. Then we attached specific attributes such as the year or period of construction, the year of the last interventions/restorations/reconstructions over time, etc. to each vector object. In this way it was possible to generate a number of maps that emphasize the old ecclesiastic city centre, the monuments in unstable areas etc. This attributes data base can be updated in real time, and in this way the governmental institutions can decide their conservation policies in a more accurate way, comparing with the traditional methods. The updated data regarding the conservation status of ecclesiastical heritage represent an important component in monitoring, protection and valorisation processes of local heritage and, in the same time, offer the possibility to involve the members of local community into heritage management for a sustainable development.
