El indigenado en la provincia de Buenos Aires
Los primeros conocimientos de los pobladores aborĂgenes del Sur de la provincia son debidos a Juan de Garay, el fundador de Buenos Aires. Por la descripciĂłn que Ă©l hace, podemos sacar conclusiones de que su origen fuĂ© en las provincias de Cuyo.
Una centuria y media despuĂ©s, es sabido, histĂłricamente, que esos elementos han sido sustituidos por los autĂłctonos de RĂo Negro y NeuquĂ©n, pero dos dĂ©cadas mĂĄs tarde ellos debieron a su regreso, entregar la tierra a los âaraucanosâ quienes habĂan venido a travĂ©s de los Andes desde principios del siglo XVI. Los descubrimientos antropolĂłgicos en la penĂnsula de San Blas con sus calaveras humanas decoradas geomĂ©tricamente en diversos colores, son un documento testimonial impecable de sus orĂgenes cuyanos y son los descubrimientos de Malacara, Juancho, Los Talas y BanderolĂł por sus señales evidentes de tener un esqueleto de sus cuerpos.
El âaraucanoâ de la Ă©poca de la campaña del desierto fuĂ© producto de una hibridizaciĂłn en las Ășltimas tres centurias; de ahĂ que no podamos esperar que sus descendientes sean tipos puros. Ya en ese tiempo el cacique principal tenĂa rasgos fĂsicos del tipo europeo. La experiencia antropolĂłgica señalĂł que la herencia de la altura y la forma craneana (Ăndice cefĂĄlico) es completamente falso. La complexiĂłn, el color de los ojos y el color del cabello son los tres rasgos que pueden ayudar mĂĄs exactamente para tener una remembranza fĂsica de sus antecesores. Los pocos granjeros de âLos Toldosâ fueron los Ășltimos sobrevivientes de la tribu de Coliqueo en su mĂĄs alto grado de constante cruza. Aparte de ello el Ă©xodo es ininterrumpido desde que comenzĂł hace 15 años; Ă©sto ha reducido al mĂnimo el nĂșmero de gente que puede ser estudiada.

Trace element contamination in the arms of the Danube Delta (Romania/Ukraine): Current state of knowledge and future needs
This paper provides the first critical synopsis of contamination by selected trace elements in the whole
Danube Delta (Romania/Ukraine) to: identify general patterns of contamination by trace elements across
the Delta, provide recommendations to refine existing monitoring networks and discuss the potential
toxicity of trace elements in the whole Delta. Sediment samples were collected between 2004 and 2007
in the three main branches of the Delta (Chilia, Sulina and Sfantu Gheorghe) and in the secondary delta of
the Chilia branch. Samples were analyzed for trace elements (Cd, Co, Cr, Cu, Ni, Pb, V, and Zn) and TiO2,
Fe2O3, MnO, CaCO3 and total organic carbon. Cluster analysis (CA) and Principal Component Analysis
(PCA) showed that levels of Cd, Cu, Pb, and Zn were influenced by anthropogenic activities. At the
opposite, concentrations of Cr and Ni largely originated from the weathering of rocks located in the
Romanian part of the Danube catchment and naturally rich in these elements. Data analysis using Self-
Organizing Maps confirmed the conclusions of CA/PCA and further detected that the contamination
tended to be higher in the Chilia and Sulina arms than in the Sfantu Gheorghe arm. The potential
ecological risks due to trace element contamination in the Danube Delta could be identified as moderate
and localized, provided that the presence of the natural sources of Cr and Ni was properly considered.
The available results suggest that monitoring sediment quality at the mouths of Sulina and Sfantu
Gheorghe arms is probably enough to get a picture of the sediment quality along their entire lengths.
However, a larger network of monitoring points is necessary in the Chilia and secondary Chilia delta to
account for the presence of local point sources and for the more complex hydrodynamic of this part of
the Danube Delta
Pain Distraction During Awake Major Colorectal Surgery: Supporting Patients Beyond the COVID-19 Era. Preliminary Findings
Introduction: During the coronavirus disease 2019 (COVID-19) pandemic, hospitals rapidly ran out of intensive care beds. Because minimally invasive surgery and general anaesthesia are both aerosol-generating procedures, their use has become controversial. We report a case series of awake undelayable colorectal surgeries which, innovatively, took advantage of intraoperative pain distraction. Moreover, we describe our frugal solution to social distancing in psychological support of inpatients.
Methods: Between October 2020 and February 2021, five patients underwent acute-care colorectal surgery under locoregional anaesthesia in our department. A 3D mobile theatre (3DMT) was used during the operation to distract the patients from pain. Vital signs, pain intensity, ergonomic comfort/discomfort, sense of presence and distress were intraoperatively monitored. A postoperative âcuddle deliveryâ service was instituted: video messages from relatives and close friends were delivered daily to the patient through the 3DMT. Emotional effects were investigated through clinical interviews conducted by a psychologist at our hospital.
Results: Both intraoperative and postoperative pain were always well controlled. Conversion to general anaesthesia and postoperative intensive support/monitoring were never necessary. The âcuddle deliveryâ initiative helped patients fill the emotional gap created by the strict containment measures implemented inside the hospital, distracting them from emotional anxiety and physical pain.
Conclusions: During the next phase of the COVID-19 pandemic and even after the COVID-19 era, awake laparotomy under locoregional anaesthesia may be a crucial option for delivering acute-care surgery to selected patients when intensive care beds are unavailable and postponing surgery is unacceptable. We also introduce a new modality for the provision of emotional support during postoperative inpatient care as a countermeasure to the restrictions imposed by social distancing measures
Teaching design in emerging countries A train-the-trainer methodology
Design disciplines have constantly evolved to keep up with the emerging demands of the 21st Century. Design education is thus called to change its methods, tools and approaches. There is an increasing interest in emerging economies in design education, especially in India, where the role of creativity, communication and technology can support social and economic development. This paper aims to present the educational approach developed in the context of the Erasmus+ KA2 project entitled âDesign and Innovation Capacity Building in India/DESINNOâ. The modernisation and internationalisation of Indian universities with innovative and contemporary design courses have been the main goals of a set of research and training activities. In this paper, the state-of-the-art methodologies in design thinking, sustainability, design research, social innovation and ethical issues in design are presented, leading to a bespoke educational approach that provides a platform for Indian design academics to apply modern educational approaches
to their specificities and needs
New application of superconductors: high sensitivity cryogenic light detectors
In this paper we describe the current status of the CALDER project, which is
developing ultra-sensitive light detectors based on superconductors for
cryogenic applications. When we apply an AC current to a superconductor, the
Cooper pairs oscillate and acquire kinetic inductance, that can be measured by
inserting the superconductor in a LC circuit with high merit factor.
Interactions in the superconductor can break the Cooper pairs, causing sizable
variations in the kinetic inductance and, thus, in the response of the LC
circuit. The continuous monitoring of the amplitude and frequency modulation
allows to reconstruct the incident energy with excellent sensitivity. This
concept is at the basis of Kinetic Inductance Detectors (KIDs), that are
characterized by natural aptitude to multiplexed read-out (several sensors can
be tuned to different resonant frequencies and coupled to the same line),
resolution of few eV, stable behavior over a wide temperature range, and ease
in fabrication. We present the results obtained by the CALDER collaboration
with 2x2 cm2 substrates sampled by 1 or 4 Aluminum KIDs. We show that the
performances of the first prototypes are already competitive with those of
other commonly used light detectors, and we discuss the strategies for a
further improvement
