Some examples are given from Perú and the United States Se presenta la curación de los restos humanos momificados desde el punto de vista del paleopatólogo. La preservación del cuerpo (y muestras) después de su estudio consiste en: (1) El tipo de proceso de momificación usado y el deterioro desde entonces; (2) El método de estudio utilizado (radiología y/o autopsia no destructiva: maximizando la información, y reduciendo al mínimo el da o); (3) Restauración individualizada; y (4) Almacenaje (incluyendo muestras y documentos): ambiente y barreras de insectos. Finalmente, se recalca el respeto que merece cada cuerpo humano, como también leyes y creencias de cada nación y se presentan algunos ejemplos de Perú y los Estados Unidos
Lenguaje, ontología y relaciones interteóricas: en favor de un genuino pluralismo ontológico
Lombardi, Olimpia,Pérez Ransanz, Ana Rosa
Arbor : Ciencia, Pensamiento y Cultura , 2011, DOI: 10.3989/arbor.2011.747n1005
Abstract: The aim of this paper is to discuss the problem of intertheoretical relationships from the perspective of an ontological pluralism based on a Kantian rooted realism. For this purpose we begin by recalling the classical concept of reduction and its shortcomings, stressing the metaphysical assumptions involved in such conception. Next, we analyze another outspread position that conceives intertheoretical relations in terms of functional relationships, in order to underline certain misguided conclusions usually drawn from that kind of relationship. This task leads us to point out a problem usually ignored in these discussions, the problem about the way in which the system under study is defined. Finally, we introduce a general characterization of our Kantian rooted ontological pluralism, and try to show how this pluralism, in its synchronic version, allows us to face the problem of inter-theoretical relations in a philosophically fruitful way. En este artículo nos proponemos discutir el problema de las relaciones interteóricas desde la perspectiva de un pluralismo ontológico que adopta un realismo de raigambre kantiana. Para ello comenzamos por recordar el concepto tradicional de reducción y sus limitaciones, poniendo el énfasis en los supuestos metafísicos que conlleva tal concepción. A continuación, analizamos otra difundida postura que concibe las relaciones interteóricas en términos de relaciones funcionales, a fin de poner al descubierto ciertas conclusiones inadecuadas que suelen inferirse de tal interpretación. Esta tarea nos conduce a se alar un problema generalmente ignorado en las discusiones sobre el tema, el cual se refiere al modo como se define el sistema bajo estudio. Finalmente, presentamos una caracterización general de nuestro pluralismo ontológico de filiación kantiana, e intentamos poner de manifiesto cómo, en su versión sincrónica, tal pluralismo nos permite afrontar el problema de las relaciones interteóricas de un modo filosóficamente fecundo.
Variational Estimates using a Discrete Variable Representation
M. Lombardi,P. Barletta,A. Kievsky
Physics , 2004, DOI: 10.1103/PhysRevA.70.032503
Abstract: The advantage of using a Discrete Variable Representation (DVR) is that the Hamiltonian of two interacting particles can be constructed in a very simple form. However the DVR Hamiltonian is approximate and, as a consequence, the results cannot be considered as variational ones. We will show that the variational character of the results can be restored by performing a reduced number of integrals. In practice, for a variational description of the lowest n bound states only n(n+1)/2 integrals are necessary whereas D(D+1)/2 integrals are enough for the scattering states (D is the dimension of the S matrix). Applications of the method to the study of dimers of He, Ne and Ar, for both bound and scattering states, are presented.
Precision measurements of timing characteristics of the 8" ETL9351 series photomultiplier
O. Ju. Smirnov,P. Lombardi,G. Ranucci
Physics , 2004,
Abstract: During the test measurements of the PMTs to be used in the future Borexino experiment, the data from 2200 PMT were accumulated. The unique timing characteristics of the apparatus used and the large statistics acquired, permit resololution of the fine structure of the ETL9351 PMT time response. A method to obtain the probability density function of the single photoelectron counting from the experimental data is proposed and applied to derive the PMT average characteristics. For the first time, an analytical model of the single photoelectron PMT time response is proposed, describing all the features of the single photoelectron time arrival. The origin of the small amplitude pulses is explained.
Particles Removal from a Moving Tube by Blowing Systems: A CFD Analysis  [PDF]
Giovanni Lombardi, Rubens Curatola
Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.53037

The use of an air jet to clean the products during the manufacturing is usual in an industrial environment. In this paper the problem of the removal, from the inner of the tube, of the waste arising from the cutting operation by means of an air blowing system is analysed. In order to obtain indications about the real importance of the involved parameters and their effects, a numerical procedure, based on CFD analysis trough the code STAR CCM+, has been settled. The effects of the different parameters were highlighted. The results are congruent with the experience, indicating that the adopted solution is not suitable for the small tubes. Therefore, a different blowing solution is investigated, with the object to improve the cleaning capabilities of the system. The results for the new blowing solution provide a significant improvement of the capability to remove the waste arising from the cutting operation can be expected.

Abstract: a particulate feeding system based on air flluidization principles was developed at the thermal and fluids engineering group at eesc-usp. the system is basically formed of a cylindrical chamber comprising two levels of fluid bed distributor plates. the performance of the system was addressed. repeatability experiments were performed in order to check out for the possibility of solids feeding control through a sphere valve which controls the air feed rate. silica sand particles of three different size were used, with mean diameters of 152, 287 and 484 μm. experiments showed that the total particulate discharge depends on the primary air feeding rate, the distance between the exit of the feeding hopper and the primary air distributor plate, and the particulate diameter, but independs on the secondary air feeding rate. the system was observed to be of difficult control and showed poor repeatability. however, the system was found to be an excellent device for distributing the flow of solids throughout several discharge sections. for the operational conditions considered and air volumetric flowrates above 3×10-3 m3/s the deviation on the particulate mass flowrate through a given discharge section related to the average value through the four sections of the injector was always below 5 %.

Abstract: we review the case of an adult male from the nasca culture who lived in southern perú about 900 a.d. (code 67466, national museum in lima). four diagnostic levels support its diagnosis of pleuro-pulmonar and osseous tuberculosis: anatomo-radiological, bacteriological, molecular, and paleoepidemiological. to the present, the most definite cases of pre-columbian tuberculosis in the americas proceed from coastal southern perú and northern chile, where five out of approximately 1000 mummies studied by different authors have been clearly diagnosed with pott's disease. today, this disease reflects ± 1% of all tuberculosis cases. appropriate calculations permit us to estimate a high prevalence of tuberculosis in this area during pre-columbian times. we postulate that tuberculosis has existed in this area since the early intermediate period, and had pandemic levels around 900 a.d

Abstract: Fable Zustovich1, Giuseppe Lombardi1, Davide Pastorelli1, Patrizia Farina1, Massimo Dal Bianco2, Luca De Zorzi2, Maurizia Dalla Palma1, Ornella Nicoletto1, Vittorina Zagonel11Oncologia Medica 1, Istituto Oncologico Veneto-IRCCS, Padova, Italy; 2UO Urologia, Ospedale Sant'Antonio, ULSS 16, Padova, ItalyAbstract: Renal cell carcinoma (RCC) is a common malignancy worldwide with approximately 95,000 new cases per year and ranks as the sixth cause of cancer deaths. Until recently, the slightly active and very toxic cytokines were available for patients with advanced RCC. Advances have been made in understanding the molecular biology of renal cancer. The introduction of targeted agents has led to promising possibilities for treating these highly vascularized tumors. Angiogenesis inhibition is likely to represent the main potential therapeutic target. Sorafenib is an oral multikinase inhibitor with activity against tyrosine kinase receptors that are responsible for blood vessel development and has shown to be active in treating advanced RCC. In this review, we summarize the pharmacology, mode of action, pharmacokinetics, and safety of sorafenib use in therapy for advanced RCC.Keywords: sorafenib, pharmacokinetics, angiogenesis
