Este artigo tem por finalidade celebrar uma das marcas da comunidade portuguesa presentes nos dias atuais dentro do território de sua antiga colônia: O Real Gabinete Português de Leitura. Situada no região histórica da cidade do Rio de Janeiro, esta vasta biblioteca foi pensada e construída como forma de salvaguardar a memória portuguesa num cenário de pós independência do Brasil. Desde o século XIX a presença dos Gabinetes de Leitura constituem parte do patrimônio português naquele que foi um dos seus maiores territórios fora da sede régia.
Abstract: This article aims to celebrate one of the marks of the Portuguese community present in the current days within the territory of its former colony: The Royal Portuguese Office of Reading. Located in the region of the city of Rio de Janeiro, this library was built as a safeguard of a memory in a post-independence scenario of Brazil. Since the nineteenth century the presence of the Reading Cabinets has been an integral part of the patrimony outside the royal residence.

Among the amphorae of the Roman city of Conimbriga, a production of a regional class of amphorae
that is not described in the bibliography was identified.
This production is characterized regarding their morphology and manufacture (regional), the proposed
general location of the production center (north of Lusitania, in all likelihood the lower Mondego
basin) and proposals are made as to their chronology and use (wine amphora from the 1st
to the 3rd century AD).

The study on archaeological evidence has evolved over the years and it is noticeable the major advances on the identification of organic products associated to archaeological artefacts, mainly ceramic vessels. This is a poorly divulged theme, traditionally supported by classical sources that sometimes specify the contents of some objects, namely of amphorae.
One of the ways found to gather more information has been the association with other scientific areas, as chemistry and biology and with the help of these sciences, the trace remains conserved in archaeological artefacts have been identified.
These themes have been approached by several research teams throughout the last few years. Unfortunately, until very recently in Portugal little work has been done on these fields, making almost impossible the recollection and analysis of this type of data by archaeologists.
The idea of publishing this book arose during the ArchaeoAnalytics meeting that took place in Esposende in September 2014, where both foreign and Portuguese researchers have joint to publicize and divulge these work methods ina archaeology.
This book collects the contribution of different researchers that have attended the meeting and presented the major breakthroughs made by the collective projects they have been involved in.
The research works here presented are grouped in three main themes. The first group gathers contributions mainly focused on General Problematics and Results, while the second and third parts are directed to Case Studies. More specifically, the second part consists of papers engaged on the use of Chromatographic Techniques in Archaeological Studies, whereas on the third part are collected research works on DNA and Archaeozoological Studies in Archaeology.

The recent discovery of garum remains in a Roman archaeological site in the south of Portugal, used for the processing and storage of fish and shellfish-based products, offers an unprecedented opportunity to pioneer biological DNA-based analyses of archaeological remains, through cutting-edge analytical methods like High Throughput Sequencing (HTS).
Our study seeks to reconstruct the species composition of the seafood products used in garum preparation of this region over the centuries IV and V, applying a combination of the DNA barcode approach with HTS technology.
Initially, primer combinations amplifying different and short fragments (<320 bp) of the cytochrome oxidase I mitochondrial gene (COI) were tested for success in amplification of DNA isolated from fish tissue. The most successful primer pair was then used to generate amplicons from 2 garum DNA isolates, and submitted to HTS sequencing in a GS 454 FLX Titanium platform.
Probably due to the old age of the DNA under examination, only a small number of reads from each sample (<200) was eligible for analyses. These reads were compared to our local comprehensive reference libraries of annotated DNA barcodes for fish and shellfish.
We found matches with between 99-100% similarity in seven different fish species. The fish species found are common in the region according to current knowledge. Replicate and additional analyses are being carried out in order to verify and deepen these findings.

Ancient oil lamps made of ceramic were used as a means of artificial lighting or symbolic context, from about 3000 BC until the discovery of electric light in the nineteenth century. This type of lighting, which used animal or vegetable fats as fuel, accompanied human civilization for millennia and always had a character of the utmost importance, either by its utility or its meaning, as a source of an element essential to human life – light. Three ceramic oil lamps, part of the Egyptian Collection that was donated to the University of Porto, in 1927, by the Berlin State Museums in compensation for the return to Germany of the archaeological collection of artefacts from Mesopotamia that had been seized in Lisbon with the German ship "Cheruskia", at the beginning of First World War. The site where the lamps were found is unknown. It's known that they were acquired in Fayum oasis, at the end of XIX century and, later, by the Neues Museum of Berlim.
When examined under long wave (380 nm) and short wave (254 nm) UV radiation, the “frog-lamp” and one of the D-type (40.01.83) showed fluorescence and phosphorescence in nozzle and inside, a reaction that raised the hypothesis of organic remains existence. This research aims to contribute to its identification. Small samples of inside material were taken by scrapping the surface. Part of the powder collected was subject to Soxhlet extraction with organic solvents and the extracts were analysed by gas chromatography with mass spectrometry (GC-MS). Other part of the powder was subject to scanning electron microscopy and X-ray
microanalysis (SEM-EDS).

Particulate matter, either with aerodynamical diameter below 10 mum (PM10) or the fine (aerodynamical diameter below 2.5 mum, PM2.5) or coarse (aerodynamical diameter between 2.5 and 10 mum, PM2.5-10) modes only, are presently regarded as one of the main threats to public health instigated by air pollution. The levels of ambient air particulates are regulated but the limits are frequently surpassed. It is therefore necessary to identify and quantify PM sources and their variability, as well as the biogenic processes that to some extent control their ambient load, in order to effectively regulate on the anthropogenic activities which originate PM. PM2.5-10 and PM2.5 were monitored in Oporto, NW Portugal, at two contrasting sites (directly impacted by traffic, roadside, and at the urban background) during two one-month campaigns (winter and summer). Sampling was conducted independently during daytime and night-time. Out of the 207 sampling periods analysed, 38 (18%) were above the European legal PM10 limit of 50 ?g m-3. PM2.5 concentrations above the limit of 25 ?g m-3 proposed by the EC occurred in 70 out of 202 sampling (35%). More exceedances occurred in winter than in summer and at roadside than at the urban background. Within the scope of this work, the relationship between PM concentrations, namely the occurrence of exceeding PM limit values, and meteorological variables or the sampling period (day/night, work day/weekend) and will be presented. Besides PM mass, the soluble ionic composition (Cl-, SO42-, NO3-, Na+, NH4+, K+, Ca2+ and Mg2+) as well as the elemental composition (Al, Si, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ga, As, Se, Br, Rb, Sr, Zr, Sn, Ba and Pb) were also determined. This allowed the application of multivariate analysis (principal component analysis with multi-linear regression analysis, PCA-MLRA, and positive matrix factorisation, PMF). Five main sources were identified in the fine and coarse modes (direct road traffic emissions, industrial activities related with refuse incineration or metallurgy, soil dust emissions, sea salt and fuel oil combustion coupled to secondary formation). The contribution of the various sources or source types to the PM load was calculated. A comparison between the relative contribution of the various sources or source types during exceeding and non-exceeding periods is conducted in order to assess if the exceeding periods may be attributed to a particular origin. Also, the concentration and relative contribution to total PM mass of the various PM constituents measured during exceedance and non-exceedance episodes is compared in order to assess their variability between the two types of events.
