Corr) For Archaeological Conservation Of Ancient Cannon Bullets In The Collection Of The Preservation Agency Of South Sulawesi Cultural Heritage. Supervised by, Akin Duli and Khadijah Thahir MudaThis study aims to determine the effectiveness of the use of traditional materials against ancient cannon bullets from Preservation Agency Of South Sulawesi Cultural Heritage. Conservation of ancient cannon bullets made of ferrous metal is carried out because there is damage in the form of chemical weathering that is the presence of corrosivity on the surface. The traditional material in this study using maja fruit (Aegle Marmelos (L). Corr).Archaeological conservation using traditional materials is done to reduce the use of synthetic chemicals. This is done because traditional materials are based more on local wisdom. The method used in this study is using two treatments. Treatment 1 uses maja water solution and treatment II uses maja meat. Based on the two treatments, the author wants to find out how long it takes to eliminate corrosion on the surface of ancient cannon bullets. The results of this study indicate that the use of Maja fruit is effectively used to remove corrosion in ferrous metals, especially ancient cannon bullets. Based on both treatments, the use of maja meat solution is more effective than using maja water solution. This is evidenced by the time difference. Maja meat solution only takes 3 x 24 hours while the solution of maja water requires 8 x 24 hours to remove corrosion on the surface.Keywords: archaeological conservation, maja fruit, ferrous metal, ancient cannon bullets.xviii + 75 hlm.; ilust
Direct alloreactivity is more susceptible to regulation by natural regulatory T cells than indirect alloreactivity.
No full textInternational audienceThe contribution of natural CD4(+)CD25(+) regulatory T cells (nTregs) in controlling graft rejection and the mechanism used remain controversial. Using the duality of the 2.102 TCR Ag recognition, we were able to study, for the first time to our knowledge, the involvement of nTregs in the two pathways of allorecognition in a murine adoptive transfer model in which TCR-transgenic nTregs were or were not depleted before transplantation. We show that nTregs used at a physiological ratio were able to delay graft rejection after direct alloreactivity by controlling proliferation and differentiation of alloreactive CD4(+) conventional T cells in draining lymph nodes. In contrast, similar results were found in the indirect alloreactivity pathway only when nTregs were used in high numbers. In the latter pathway, nTregs used at a physiological ratio failed to delay graft rejection and to control proliferation of conventional T cells. These results support recent therapeutic approaches aimed at producing and using in vitro Ag-specific Foxp3(+) nTregs to control graft rejection in transplantation. Finally, late inhibition of Th1 differentiation was shown in indirect alloreactivity, but this suppression could also be mediated by Foxp3(+)-induced Tregs

The Arab Republic of Egypt and the Coptic Orthodox population
No full textThis essay explores the persecution of the Coptic Orthodox people of Egypt, and how it impacts the government’s ability to thrive as a Democratic Republic. The Egyptian government defines itself as an Arab Republic, but does not completely practice secularism. The Egyptian constitution, states Islam as the religion of the state and the principles of Islamic Sharia are the principle source of legislation. This capstone analyzes the historical marginalization of Coptic Egyptians supported by mass conversion, violence, erasure of language, and seizure of property which all directly contribute to the continuing persecution of this set of the population. This paper will discuss the need for secularization by discussing the marginalization of Coptic Christians in modern Egypt beginning with Anwar Sadat’s presidency to post revolution Egypt. It will also explore the failures of Mubarak’s administration and how the marginalization of Coptic Christians contributed to the government’s downfall. This essay will then explore the conditions of post-revolutionary Egypt, and the repetition of Islam as the state religion leading to continued marginalization. In order for Egypt to thrive as a Republic it should practice secularization. This includes limiting the rule of the majority, not declaring an official state religion, enforcing religious freedom, strengthening human rights policies, and providing adequate representation for the Coptic community within the governing body.M.A.Includes bibliographical reference
Cerebrospinal fluid IL-10 as an early stage discriminative marker between multiple sclerosis and neuro-Behçet disease.
No full textInternational audienceMultiple Sclerosis (MS) and Neuro-Behçet's Disease (NBD) are two recurrent disorders affecting the central nervous system (CNS) by causing inflammation and irreversible damage. Inaugural clinical symptoms for both diseases might be very similar and definitive diagnosis could be delayed. The present study aimed to find out possible differences at early stages in the transcription factors/cytokines expression profiles in blood and cerebrospinal fluid (CSF) of MS and NBD patients which could be useful discriminative markers. Cytokines and transcription factors related to Th1, Th2, Th17 and T regulatory populations were studied by quantitative RT-PCR simultaneously in PBMCs and CSF, from 40 patients presenting a first episode of clinical features related to CNS inflammation and 22 controls with non inflammatory neurological diseases enrolled mainly for severe headache. The follow up of 12 months did allow a definitive diagnosis of remitting relapsing MS (RRMS) in 21 patients and of NBD in the other 19 among those with CNS inflammation compared to controls. In initial blood samples, T-bet was significantly increased in NBD patients only while IFN-γ was elevated in patients who evolved into RRMS or NBD. IL-17a, GATA-3 and IL-4 were significantly lower in RRMS patients than in the NBD group. In initial CSF samples, ROR-γt, IL-17a and IFN-γ were significantly elevated in patients compared to controls. The most striking finding was the significant increase of CSF IL-10 that we did observe in NBD patients only. Thus, we propose CSF IL-10 as a predictive marker to help clinicians discriminating between these two neurological disorders

Abstract
The mass movement, and especially the instability of the soil and rocks, play a significant role in the changing aspect and the evolution of the landscape worldwide and particularly in tropical region. In Central Africa the landslides and others kind of instabilities are very frequent, important and represent a real threat for both population and economy. The case of Rwanda is remarkable, this country which is known as the country of thousand hills, is rich of various and very complex morphology caracterized by very steep slopes crossed by a dense network of watercourse, powered by a considerable amount of precipitation distributed in two wet seasons. The growing economy of the country brings a lot of project of infrastructures and mines and quarries exploitation (embankments and cuttings) which have a strong impact on the triggering of huge instabilities and so the modification of landscape. These instabilities and the intense activity of the rivers and streams could be considered as the engine who control the shaping and the remodeling of the landform. To understand the evolution process of these instabilities, and then the landscape change we started by the mapping of the instabilities using satellite images and then we went on the field to validate the inventory to identify the morphological aspect of the terrain, to refine our knowledge of the geological nature of the materials by sedimentological analyses on selected samples, and of course to try to better know the impact of the rock's weathering process leading to the constant modification of the landform. The computer-based quantitative analyses using GIS's data processing, were carried out to help to understand the distribution of the instabilities and the geomorphological phenomena observed to better connect and explain the whole information collected. The aim of the study is to bring in more than the mapping of instabilities a response about the process and the evolution of the instabilities and the factors impacting the phenomenon.GeoRisC

ANÁLISE SOBRE A POSSÍVEL CONTRADIÇÃO OU HARMONIA ENTRE OS CONCEITOS DE SOBERANIA E DE PROPRIEDADE PRIVADA NO PENSAMENTO DE JEAN BODIN
No full textNesta pesquisa, pretendemos analisar o pensamento político de Jean Bodin (1530-1596), destacando a sistematização da noção de soberania e os limites para o exercício do poder da realeza na época moderna. Neste sentido, busca-se verifi car o discurso político de Bodin e como este autor foi importante para organizar o conceito de soberania relacionado ao poder dos reis, bem como para a defi nição dos limites do exercício do referido poder soberano por meio das chamadas leis divinas e naturais, incluindo-se, neste ponto, o direito de intangibilidade da propriedade privada. Por fi m, evidencia-se a importância da obra de Bodin por meio da análise da existência ou não de uma contradição ou de uma harmonização entre os conceitos de soberania e de propriedade privada presentes nos estudos efetivados por Bodin.

ANALYSIS OF THE POSSIBLE CONTRADICTION OR HARMONY BETWEEN THE CONCEPTS OF SOVEREIGNTY AND PRIVATE PROPERTY IN JEAN BODIN THOUGHT
In this research, we intend to analyze the political thought of Jean Bodin (1530-1596), highlighting the systematization of the notion of sovereignty and the limits to the exercise of the power of royalty in modern times. In this sense, we seek to verify Bodin’s political discourse and how important this author was to organize the concept of sovereignty related to the power of kings, as well as to defi ne the limits of the exercise of that sovereign power through the so-called divine laws and natural resources, including, at this point, the right to intangibility of private property. Finally, the importance of Bodin’s work is evidenced through the analysis of the existence or not of a contradiction or of a harmonization between the concepts of sovereignty and private property present in the studies carried out by Bodin.
