Centralized formation control of non-holonomic mobile robots
Carelli,R.; de la Cruz,C.; Roberti,F.;
Latin American applied research , 2006,
Abstract: this work presents a control algorithm for a group of non-holonomic mobile robots that must attain coordinately a specific formation, which can be fixed or moving in the work space. the control error is defined in terms of location, size and shape of the constellation of points placed by the robots and the constellation of objective points. the stability analysis of the proposed control system is included along with the results from simulation and laboratory experiencies which validate the good performance of this robot formation control system.

El enfoque biográfico en el análisis social: claves para un estudio de los aspectos teórico-metodológicos de las trayectorias laborales
Roberti Eugenia
Revista Colombiana de Sociología , 2012,
Abstract: Este trabajo desarrolla los supuestos que se esconden tras los estudios biográficos, centrándose en los enfoques europeo y norteamericano. Intenta vislumbrar los distintos ámbitos de producción en donde surgieron los fundamentos epistemológicos, teóricos y metodológicos, los cuales enmarcan el análisis de las trayectorias: la centralidad del sujeto, la relación individuo-sociedad, la integración de perspectivas metodológicas y la importancia de la dimensión espacio-temporal. La relevancia de esta tarea radica en que el enfoque biográfico se constituye como telón de fondo en el estudio de las trayectorias laborales. En el primer apartado se indagan los orígenes del uso de biografías en la investigación social; en el segundo y el tercero, se examinan los supuestos centrales del enfoque biográfico y del curso de vida, al encontrar en ellos las raíces que encuadran y dan sentido al estudio de las trayectorias. Por último, se desarrollan los aportes y potencialidades de los estudios con trayectorias laborales a través del análisis de un corpus de investigaciones empíricas producidas en América Latina.

Presen?a de anticorpo anti-Lutheran B em paciente com leucemia linfóide aguda
Roberti, Maria do Rosário F.;Tuma, Cristiane A.;Maciel, Janeslane F.;
Revista Brasileira de Hematologia e Hemoterapia , 2007, DOI: 10.1590/S1516-84842007000200019
Abstract: acute leukemia needs hemotherapeutic support to be successfully treated. the lutheran b antibody, specifically the high frequency of this antigen in our population, has made it difficult to treat hematological malignancies that need transfusional support, including acute lymphoblastic leukemia. finding compatible blood is complex and so the authors adopted a conservative treatment strategy. the prescription of epoetin and an individualized chemotherapy protocol may improve results. we describe a case report of a patient with anti-lutheran b antibody and how difficulties to find compatible blood were solved.
Luminiscence quenching of europium (III) and terbium (III) carboxylates by transition metals in solution
Barja,B. C.; Remorino,A.; Roberti,M. J.; Aramendia,P.F.;
Anales de la Asociaci?3n Qu?-mica Argentina , 2005,
Abstract: the quenching of eu(no3)3.6h2o (1), {[eu3(crot)9(h2o)4].h2o.etoh}n (2), [eu2(oda)3.(h2o)2].5h2o}n (3), na3[eu(oda)3].2naclo4.6h2o (4), na3[eu(dpa)3].15h2o (5), tb2(ch3coo)6.2h2o (6), and [tb(hoda)3].h2oda (7), where hcrot (trans ch3-ch=chcooh), h2oda (hooc-ch2-o-ch2-cooh) and h2dpa are crotonic, oxydiacetic, and 2,6- pyridinedicarboxylic acids, respectively, by cu(ii), ni(ii), and co(ii) was studied in aqueous solutions at room temperature. the hydration number of each lanthanide complex was estimated from their excited state lifetime in h2o and in d2o. this value was used to infer the identity of the main species in solution and consequently its electric charge. the dynamic quenching constant shows the influence of the electrostatic interaction. the quenching process is exclusively dynamic for compounds 1 - 4, 6, and 7, while compound 5 shows static and dynamic quenching for the three transition metal ions. the values of the quenching rate constants exceed the energy transfer expectations and show evidence of a collisional mechanism. specially for compound 4 detection limits for cu(ii) in the range required for drinking water levels are reached.
Macroglobulinemia de Waldenstr?m com hemorragia intra-ocular
Nassaralla Júnior, Jo?o J.;Roberti, Maria do Rosário F.;
Revista Brasileira de Hematologia e Hemoterapia , 2006, DOI: 10.1590/S1516-84842006000400020
Abstract: the aim of this work is to report a case of waldenstr?m's macroglobulinaemia involving both retinal and choroidal circulation that resolved after treatment. the design is an interventional case report. a 47-year old male was admitted for evaluation of anaemia, and groin lymphadenopathy. a diagnosis of waldenstr?m's macroglobulinaemia was made based on clinical and laboratory findings. the patient developed intraocular hemorrhage without associated hypertension and with normal coagulation profile. a funduscopic examination revealed marked dilation and beading of the venous system, microaneurysms, and telangiectatic capillary beds in the posterior pole. a fluorescein angiography showed delayed choroidal filling, prolonged arteriovenous transit time and areas of capillary non-perfusion. these findings were accompanied by a severe igm increase in serum viscosity. the most important ocular findings were reversible after plasmapheresis. waldenstr?m's macroglobulinaemia can involve both retinal and choroidal circulation. the prominent microvasculopathy is reversible after appropriate treatment.
The Social Demand for a Medicine Focused on the Person: The Contribution of CAM to Healthcare and Healthgenesis
Paolo Roberti di Sarsina
Evidence-Based Complementary and Alternative Medicine , 2007, DOI: 10.1093/ecam/nem094
Abstract: The Non Conventional Medicines have a greater social impact and the demand for such treatments of more than 10 million Italian citizens (male and female) of all ages and social classes and of thousands of Italian families reveals an interest proving that there is a trend reversal, involving also other sectors of the medical and scientific world, which shifts the focus from the symptom to an idea of more general and comprehensive well-being of the person. Over the last few years the scientific debate on Non Conventional Medicines and their integration with the academic or dominant medicine in our western society has favored and legitimated an increase in the demand and has activated a cultural transformation process involving the life styles. The focus is therefore shifted to the self-healing capacities, to the reawakening of the individual potentialities, which support and amplify the benefits of the treatments and the citizens start pretending to be accurately informed in order to choose freely their own health program.
Ch?gyal Namkhai Norbu Rinpoche: Dzogchen and Tibetan Tradition. From Shang Shung to the West
Paolo Roberti di Sarsina
Religions , 2012, DOI: 10.3390/rel3020163
Abstract: In July 2011 the International Dzogchen Community celebrated its 30th Anniversary. In 1981, near Arcidosso in Tuscany (Italy), Master Ch?gyal Namkhai Norbu Rinpoche founded the first community or Gar of the International Dzogchen Community. He named it “ Meri-gar”, the “Community of the Mountain-of-Fire”. In the 70s Ch?gyal Namkhai Norbu began to teach Dzogchen to his first students. Interest soon became widespread and having received invitations from all continents, Ch?gyal Namkhai Norbu Rinpoche began to travel and teach throughout the world. These last thirty years the Dzogchen Community has grown and now has thousands of members in over 40 countries and all continents. The main objective of the Community is to preserve and develop understanding of Dzogchen, as well as preserving Tibet's extraordinary cultural patrimony. The International Shang Shung Institute for Tibetan Studies was founded by Ch?gyal Namkhai Norbu Rinpoche with this aim and it was inaugurated by His Holiness the 14th Dalai Lama in 1990. It has a rich collections of Tibetan books and manuscripts and publishes the teachings of Ch?gyal Namkhai Norbu. This article draws on Ch?gyal Namkhai Norbu’s work and legacy to describe the Dzogchen Lineage and Tibetan Tradition from the very origin of the Shang Shung Culture.
