Análise de proveniência das contas verdes dos Perdigões

A variscite é um mineral raro que oferece uma excelente opotunidade de estudo dos padrões de comércio e troca na Europa durante a Pré- História através da determinação da sua fonte de proveniência. No presente texto será discutida a proveniência das contas de colar verdes com base em análises de XRF e XRD, através das quais se criou uma identidade geoquímica passível de ser comparada com as das fontes de variscite conhecidasVariscite is a rare mineral that offers an excellent opportunity to study trade and exchange patterns in prehistoric Europe through proveniencing of source material. In this paper we discuss the provenance of Perdigões’ green beads by means of XRF and XRD analyses, thus creating a geochemical baseline that is compared with that of the known variscite source

Experiences of poverty amongst low-income older adults living in a high-income country: A qualitative study

Aim: To understand the experience of low-income older adults living in poverty in a high-income country. Design: A qualitative study based on Gadamer's hermeneutic phenomenology. Methods: A convenience sample of twenty-seven low-income older adults were interviewed in-depth between September 2021 and January 2022. Fleming's method for conducting phenomenological qualitative studies was followed and ATLAS.ti software was used for data analysis. Results: Three main themes were extracted from the analysis: (i) ‘living in the shadow of poverty’, (ii) ‘unprotected by the ‘social shield’ of the welfare state’ (iii) ‘the struggle to attain good health’. Conclusion: Living in poverty affects all spheres of life. Older adults living in poverty feel excluded from social support policies and laws. This has a negative impact on the older adults' mental health and can lead to social isolation. Implications for the Profession and/or Patient Care: Nursing interventions to promote health amongst older adults living in poverty should include an assessment of the patient's social determinants and a focus on increasing social participation. Older people living in poverty experience difficulties accessing formal social support so nurses should implement patient navigation interventions that aim to help them overcome the complexities of the system. Nursing interventions to improve mental health amongst older adults living in poverty are much needed. Impact: Living in poverty increases older adults' vulnerability. Older adults living in poverty suffer from mental health issues as they live under constant pressure to meet their basic needs and lack formal social support. These findings are important for nurses, who play a pivotal role in the design, implementation and evaluation of policies and interventions that promote health equity. Reporting Method: The study has been conducted following the COREQ guidelines. Patient or Public Contribution: There has been no public or patient involvement in the design or development of the study.Knowledge Transfer Programme from the University of Almería, Grant/Award Number: TRFE-SI-2021/00

Radiocarbon chronology of dolmens in the Iberian southwest: architectural sequence and temporality in the el Pozuelo megalithic complex (Huelva, Spain)

This paperes tablishes the chronologyof the ElPozuelo megalithic complexand discusses it in the context of other dolmens that have been dated in the southwest of the Iberian Peninsula. The working methodology combines the study of the stratigraphy and architectural sequence with the Bayesian modeling of the 27 AMS 14C dates obtained for charcoal samples from the four monuments in the Los Llanetes cluster. The most significant chronological results (at 68% probability) are (a) the antiquity and long duration of the megalithic sites, in which several monumental structures succeeded one another ca. 3970–1980 cal BC; (b) the existences of different temporalities in the LateFinal Neolithic dolmens: simple chambers (3970–3760 cal BC), elongated chambers (3790–3620 cal BC) and multiple chambers (3660–3260 cal BC; (c) the continuity of activity during the Copper Age (2980–2580 and 25302180 cal BC); and (d) the permanence of megalithism in the Early Bronze Age, through the presence of terraced enclosures with circular platforms ca. 2230–1940 cal BC. This diachronic sequence and the contextualized analysis of the 152 available radiocarbon dates (27 new, 125 published) supports the establishment of the temporal dynamics of megalithism in the Iberian southwest, introducing key aspects on the emergence, span, and rebuilding of the different dolmens (passage graves, simple chambers, elongated chambers, and multiple chambers) and establishing the phases of activity and reuse of the different architectural types.This study has been carried out within the framework of the R D i Project “MEGA-LITHOS. Geo-archaeological study methods for the investigation of the Huelva megalithisms” (UHU- 1263153) at the University of Huelva, funded by the Operative Programme ERDF 2014-2020 and the Department of Economy and Knowledge in the Government of Andalusia. The radiocarbon dates were commissioned at the CNA by the Culture Department in the Government of Andalusia within the Exceptional Archaeological Activity under our direction. The funding of the open access charge has been assumed by the University of Huelva, thanks to the agreement established with Cambridge University Press. I am grateful to Coronada Mora Molina for her invaluable participation in the excavation and research of the Los Llanetes cluster.

M´onica Ruiz Alonso has contributed to the anthracological study of the charcoal samples. Thanks to the reviewers for their comments and suggestions, which have improved several aspects of the wor

Retinal ganglion cell software and FPGA model implementation for object detection and tracking

This paper describes the software and FPGA implementation of a Retinal Ganglion Cell model which detects moving objects. It is shown how this processing, in conjunction with a Dynamic Vision Sensor as its input, can be used to extrapolate information about object position. Software-wise, a system based on an array of these of RGCs has been developed in order to obtain up to two trackers. These can track objects in a scene, from a still observer, and get inhibited when saccadic camera motion happens. The entire processing takes on average 1000 ns/event. A simplified version of this mechanism, with a mean latency of 330 ns/event, at 50 MHz, has also been implemented in a Spartan6 FPGA.European Commission FP7-ICT-600954Ministerio de Economía y Competitividad TEC2012-37868-C04-02Junta de Andalucía P12-TIC-130
