L'intégration animale et végétale comme facteur favorisant les performances des systèmes polyculture élevage ; Mixed farming systems assessment according to crop livestock integration : case studies in Guadeloupe (FWI) Auteur(s) : Franchone, Audrey Année de publication : Loading the player... Éditeur(s) : INRA : Institut National de la Recherche Agronomique Université des Antilles. Service commun de la documentation Extrait de : 52e congrès annuel de la Société caribéenne des plantes alimentaires / 52nd annual meeting of the Caribbean food crops society (CFCS), du 10 au 16 juillet 2016. INRA, CFCS Description : In the new context of the agro-ecological transition, present agricultural systems will have to produce more and better in a more constraint world. Mixed crop livestock systems (MCLS) represent sound alternative ways to progressively achieve these goals through crop-livestock integration (CLI). CLI exploits the synergies between cropping and livestock systems through organic fertilization with manure or plant association, use of crop residues to feed livestock, .... It offers many opportunities to improve productivity, as well as to increase resource use efficiency and improve the resilience of the whole farming system. In the scientific literature, authors advocate the interest of MLCS and CLI, based on theoretical considerations, modelling and empirical evidence from local case studies. But these studies do not clearly identify the respective roles of diversity of activities and CLI management practices in improving performances at the level of the whole farming system. Our aim was thus to assess CLI at farm scale in a range of MCLS and to explain farm performances by analyzing the combination of activities and the level of integration. We conducted our analyses in Guadeloupe, (French West Indies), where MCLS and CLI are complex but important challenges for local agricultural. In order to analyze CLI in a holistic and systemic way, we applied a method traditionally used in ecology, ecological network analysis, to study the structure, functioning and performance of agrosystems. This method was implemented on a range of Guadeloupian MCLS where CLI practices where identified. Nitrogen was retained to conduct the analysis due to its central role for both animal and vegetal productions. The ENA method allows an estimation of productivity, resilience, efficiency, productivity and self- sufficiency of the flows network. Our results show that 1/ efficiency and resilience appear correlated to the complexity and intensity of the network of flows; 2/ efficiency and resiliency are positively correlated when we consider them in terms of N flows; 3/ in the Guadeloupian context, CLI concerns mainly specific practices, as feeding pigs with a wide range of crop residues and organic fertilization of small market gardens and plots used to grow tubers. But at whole system level, CLI remains rare and mainly depends on conventional management practices as mineral fertilization and animal complementation of some farming activities as sugar cane, cattle breeding and banana. Moreover, the combination of productions implemented determines the potential of CLI and related performances linked to relative N efficiency of each production. Consequently, performance and especially efficiency and self-sufficiency depend more on the nature of the activity than on CLI management practices. There is still a gap between theoretical studies and CLI in practice, even though CLI is more complicated than simple flows and provides other services and functions. Dans le nouveau contexte de la transition agro-écologique, les systèmes agricoles actuels devront produire plus et les améliorer dans plus de monde de contrainte. Les systèmes mélangés de bétail de culture (MCLS) représentent des manières alternatives saines d'atteindre progressivement ces buts par l'intégration de culture-bétail (CLI). Le CLI exploite les synergies entre l'emblavage et les systèmes de bétail par la fertilisation organique avec l'association d'engrais ou d'usine, utilisation des résidus de culture d'alimenter le bétail,?. Il donne beaucoup d'occasions d'améliorer la productivité, aussi bien que d'augmenter l'efficacité d'utilisation de ressource et d'améliorer la résilience du système d'exploitation agricole entier. Dans la littérature scientifique, les auteurs préconisent l'intérêt de MLCS et de CLI, basé sur des considérations théoriques, modeler et des preuves empiriques des études de cas locales. Mais ces études n'identifient pas clairement les rôles respectifs de la diversité des activités et des pratiques de gestion de CLI en améliorant des interprétations au niveau du système d'exploitation agricole entier. Notre but était ainsi d'évaluer le CLI à l'échelle de ferme dans une gamme de MCLS et d'expliquer des interprétations de ferme en analysant la combinaison des activités et du niveau de l'intégration. Nous avons réalisé nos analyses en Guadeloupe, (des Antilles françaises), où MCLS et le CLI sont des défis complexes mais importants pour agricole local. Afin d'analyser le CLI d'une manière holistique et systémique, nous avons appliqué une méthode traditionnellement employée en écologie, analyse réseau écologique, pour étudier la structure, le fonctionnement et l'interprétation des agrosystems. Cette méthode a été appliquée sur une chaîne de Guadeloupian MCLS où des pratiques en matière de CLI où identifiée. L'azote a été maintenu pour réaliser l'analyse due à son rôle central pour les productions animales et végétales. La méthode d'ENA permet une évaluation de la productivité, de la résilience, de l'efficacité, de la productivité et de l'autosuffisance du réseau d'écoulements. Nos résultats prouvent que 1 efficacités et résiliences semblent corrélées avec la complexité et l'intensité du réseau des écoulements ; 2 efficacité et élasticité sont franchement corrélés quand nous les considérons en termes d'écoulements de N ; 3 dans le contexte de Guadeloupian, CLI concerne principalement des pratiques spécifiques, en tant que les porcs de alimentation par un large éventail de résidus de culture et de fertilisation organique de petits jardins du marché et complots employés pour cultiver des tubercules. Mais à au niveau système entier, le CLI demeure rare et dépend principalement des pratiques de gestion conventionnelles en tant que complémentation minérale de fertilisation et d'animal de quelques activités agricoles comme canne à sucre, élevage et banane. D'ailleurs, la combinaison des productions mises en application détermine le potentiel du CLI et des interprétations relatives liés à l'efficacité relative de N de chaque production. En conséquence, l'interprétation et particulièrement l'efficacité et l'autosuffisance dépendent davantage de la nature de l'activité que sur des pratiques de gestion de CLI. Il y a toujours un espace entre les études et le CLI théoriques dans la pratique, quoique le CLI soit plus compliqué que des écoulements simples et fournisse d'autres services et fonctions.

Applying C-13 techniques in exploring the carbon sequestration potential of limed acid soils fromt Trinidad ; Application des techniques C-13 à l'exploration du potentiel de séquestration du carbone des sols acides calcaires de Trinidad Auteur(s) : Gouveia, Grégory Année de publication : Loading the player...

Service commun de la documentation Extrait de : 52e congrès annuel de la Société caribéenne des plantes alimentaires / 52nd annual meeting of the Caribbean food crops society (CFCS), du 10 au 16 juillet 2016. INRA, CFCS Description : Carbon dioxide (CO2) accounts for the largest proportion (74%) of total greenhouse gas (GHG) emissions globally, with agricultural activities contributing approximately 25% of this gas. Opportunities to reduce the emissions in the sector can therefore contribute significantly to mitigating global climate change. Ag-lime is used extensively to alleviate problems of soil acidity and the potential for this material to contribute to C sequestration in soils is gaining interest among researchers. A laboratory experiment using C-13 isotopic labelling techniques was therefore established to answer the following questions: 1) Is there a potential for sequestering C using ag-lime in Trinidad acid soils? 2) Does enhancing soil microbial respiration by applying labile organic amendments enhance the C sequestration potential of ag-lime? 3) Are lime-derived C (LDC) estimates from non-isotopic difference technique comparable to that from the C- 13 isotopic labelling technique? The results ascertained for the study showed significant (P<0.05) differences between the LDC estimates from the two techniques with the non-isotopic techniques yielding higher estimates. Over the 32- day experiment, between 16.4 to 85.4% of the ag-lime C was released as CO2 with values being lower for the Piarco soil. The LDC in the CO2 was also significantly (P<0.05) lower for the poultry litter treatments comparison to the other organic amendments for the Piarco soil but not the Nariva soil. This effect may not have been as a result of an enhancement of the carbon sequestration potential of the ag-lime due to an elevation in soil microbial respiration since the LDC in the glucose-amended soils did not differ significantly from the no-amendment control soils.

Forum with Parliament Members : Students Against Sexual Orientation Discrimination ; Audio Recordings of the Proceedings Auteur(s) : Caribbean IRN Résumé : From the PNCR, GAP MPs free to vote conscience on gay rights bill
By Johann Earle
Stabroek News
June 11, 2003
The PNCR will allow its members to vote their conscience on the controversial Constitution (Amendment) Act of 2001 which seeks to prevent discrimination against persons on the basis of their sexual orientation and other grounds.
A number of religious organisations are opposed to the passage of the bill because it includes sexual orientation as one of the grounds. They are concerned that it could lead to a legalisation of homosexual relations and demands for recognition of gay marriages among other things.
PNCR Member of Parliament (MP) Vincent Alexander told a forum at the National Library on Saturday, that the Bill did not seek to legalise homosexuality, but to ensure that persons would not be discriminated against based on their sexual preferences.
He was one of two parliamentarians who showed up - the other being PNCR member, Myrna Peterkin.
The forum was organised by Students Against Sexual Orientation Discrimination (SASOD), a group comprising fifteen students from the University of Guyana which was formed about two weeks ago.
Alexander expects the vote on the bill to come up before the National Assembly in a matter of months.
Paul Hardy, Leader of the Guyana Action Party (GAP), told Stabroek News that his party would not be using the so-called parliamentary whip. He added that GAP took a decision that every member should vote according to his or her own conscience. “We have no right to deny the rights of others based on sexual orientation. [The Bill] will guarantee rights to the homosexual.” GAP is in Parliament as part of an alliance with the Working People’s Alliance. GAP/WPA has two MPs.
The bill was met with rejection from some members of the religious community in 2001 and as a result of this, the President did not assent to it.
In a statement on Monday, the Central Islamic Organisa-tion of Guyana (CIOG) said that it stood in firm opposition to the Bill. The CIOG says the general purpose of the bill may be commendable and that the organisation’s objection is not based on a willingness to promote discrimination. Rather, the CIOG said, it was based on the fact that specific legal protection on the basis of sexual orientation without definition or qualification gives tacit legitimacy to practices which are considered criminal in Islam. “It is foreseeable that such a legal nod of approval (subtle as it may be) of these practices may pave the way for greater social (or even legal) acceptability in the future which, from the perspective of all Muslims including those in Guyana, is an undesirable and sinful outcome,” the CIOG statement said.
At Saturday’s event, Muslim teacher Moulana Mohamed Ali Zenjibari spoke of instances of abuse, discrimination and harsh penalties meted out to gay and lesbian persons in countries such as Iran and Saudi Arabia and noted that the Quran did not sanction such punishments for homosexual behaviour.
President of the CIOG, Fazeel Ferouz told Stabroek News that a meeting to discuss a strategy with regards to the bill was planned for tomorrow with various religious groups.
Stabroek News tried to get a comment on the issue from the PPP/C but to no avail.
ROAR leader, Ravi Dev said that his party was now having discussions on the issue. ROAR feels that it is an important question which has to do with morality and should be discussed across the country. He added legislators had to be in tune with their constituents on the issue.
SASOD is lobbying for the legislation through the sensitisation of MPs.
Keimo Benjamin, a law student at UG, gave a presentation based on the jurisprudential aspects of the discussion on sexual orientation. He argued that morality should not be the only guiding principle on which to base the laws. Sexual activities between two consenting male adults in private could not be equated with a violation of a person’s rights, he said, making the point that the thrust of his presentation was not whether homosexuality was wrong, but whether it violated the rights of others. He said that the attitudes of some towards this subject were based on preconceived notions and prejudices. He cited studies to show that the suppression of certain perceived deviant sexual impulses in persons might do more harm than good. One Harvard University study of teens who said they were gay indicated that those teens were three times more likely to commit suicide.
Vidyaratha Kissoon, of Help and Shelter, in his contribution on Saturday, expressed his displeasure at the low turnout at the forum and urged the parliamentarians who showed up to take the message to their colleagues. He noted that because of homophobia, the numerical minority was terrified of speaking out against instances of discrimination. Gays and lesbians in Guyana were subjected to ridicule and abuse, and walk the streets at night not looking for sex necessarily, but for the companionship of persons who empathise with them.
During his presentation, Joel Simpson, another member of SASOD, outlined a number of changes made within national jurisdictions that had international implications. One such crucial change was South Africa’s 1996 adoption of a new constitution, making that country the first in the world to expressly include sexual orientation as a prohibited ground of discrimination. It was the first time a developing country had taken the lead with respect to the rights of sexual minorities.
He also said that according to Douglas Sanders, a Canadian jurist, the rights of homosexual, bisexual or transsexual men and women had never been officially recognised by the United Nations, despite the fact that international laws on the issue began to emerge at the close of the Second World War.
Simpson said that under Article 170 (5), as amended by Section 8 of the Constitution (Amendment) (No. 4) Act 2000, the President is required to assent to any bill which is returned by the National Assembly unaltered after a two-thirds majority within 90 days of its presentation to him. To the parliamentarians present, Simpson stressed that the onus was now on them to adequately represent their constituents which include lesbian, gay, bisexual and transsexual Guyanese.

Vote on sexual orientation should be a matter of conscience - MP Alexander
By Esther Elijah
Guyana Chronicle
June 8, 2003
PEOPLE’S National Congress (PNC/R) Member of Parliament Mr. Vincent Alexander, said the Opposition will vote on “conscience” when the piece of legislation on sexual orientation is again brought before the National Assembly.
“With specific reference to my party, when this Bill gets back to the Parliament in the spirit of the arguments here, we will not use the `whip’. Our party will not say we have to vote for the provision (in the Sexual Orientation Bill). We will allow our members to vote as a matter of conscience,” he told participants gathered in the Conference Room of the National Library.
“We feel this is a matter of conscience. You may end up with a collective position but you have to deal with us individually,” Alexander said at a poorly attended public consultation aimed at gaining support for sexual orientation to be considered a fundamental right in Guyana.
Alexander, one of the main persons who sat on the Constitutional Reform Commission that addressed this controversial clause, said the legislation was not meant to legalise homosexual activities in Guyana.
“It was intended to ensure that persons who have an orientation - a way of thinking - which may or may not lead to a certain activity, to not be discriminated against, in terms of their rights,” he explained.
Alexander noted that very often, discussions on the sexual orientation provision in the Bill have led to seepages into other areas where debates centre on the “right to be homosexual.”
“I am saying the Bill does not comment on that… However, law is peculiar, especially in a Common Law system. Once you venture out and change the law, very often you open other windows which we cannot definitively say exist or does not exist in advance,” he said.
“The fear of some people is that the legislators might say one thing and the Courts will eventually say something else. While some people can’t argue against the law, per say, they will say this has opened a window of opportunity not meant to be opened. So, it is better to stay without a window than open it and then have a possibility of something you didn’t intend to happen - happening sometime in the future.”
Alexander added: “I want to say I’ve found this activity to have been rich from the perspective of the amount of research which was done by student (speakers). Without any comment as to whether I agree with the arguments, I would wish that much more research on other issues be done by students, and that at the University (of Guyana) students would find it convenient to have forums on other issues, with the same depth of research for their own intellectual development.”
Alexander and other Opposition M.P, Lurlene Nestor were the only three Parliamentarians in attendance at the session organised by the recently formed `Students Against Sexual Orientation Discrimination’ (SASOD), a group that has a membership of 15 mostly University of Guyana (UG) students from various faculties.
SASOD was established two weeks ago.
With the exception of members of the press, the consultation only managed to attract 11 persons, a handful of who were SASOD members.
While congratulating the students for an “insightful” presentation, Nestor pointed out that whether or not she chooses to agree with their position is “another issue” and she is entitled to her “own view”.
“The issue of sexual orientation is very `toucheous’ …while we agree with the human rights provisions and all that as a society, we must also revert to our own society. Some of the very critical questions that I would want to ask is whether or not at the society (level) we are ready for that kind of thing,” she remarked.
“We cannot, at (any) time, ignore the religious groups in our society. If we look at statistics going back to 1992 from a survey done by the Bureau of Statistics, we would see that a small section of the Guyanese population might be considered as people who do not subscribe to a religious view. While the laws are not necessarily based on moral values, we must acknowledge the fact that we might want to revert to many of the cases that (concern) laws that protect public morality.”
Nestor told the speakers at the consultation these were some of the issues that they needed to deal with.
She highlighted, too, that what must be examined is the effects of same-sex marriages on society and how this issue must be tackled.
“These are some of the things we should consider and I don’t think you dealt with that in the presentations,” Nestor stated, adding that the issues must be addressed “frontally.”
“Do we think that with the coming to being of this Bill that there might be quite a number of challenges to the Constitution in relation to the same issue of a man marrying a man? What do we do at the society (level)? Do we recognise that?” were the questions directed at the five speakers at the session.
Nestor continued: “There is some argument that says, `Oh the Bill does not promote homosexuality or does not encourage a man to marry (another) man, but if you look at Section (15) that talks about `non-discrimination’ then how can we not, with the passage of this Bill, allow a man not to marry (another) man.”
According to Nestor, matters of this nature constitute some of the “inconsistencies” of the Bill.
On the argument raised by presenters at the session on who determines what is morality, Nestor said in the concept of democracy it is the people who are the determinants based on a “line of thinking.”
She also rebutted on grounds that put the spotlight on teachers who may have been caught “interfering” with their young students and who may subsequently be dismissed from their jobs.
“Could you imagine such a person interfering with a boy below age 10 - and by virtue of the fact that the Bill is there, the judges (in the case) will have to use their discretion in terms of what happens. We will have more Constitutional changes and problems (arising with the passage of the Bill).”
SASOD member and law student, Joel Simpson, in reply, said he doesn’t think any homosexual in Guyana wants to “run into a church and ask that people marry them or anything of that sort.”
At one point likening the church to a “club”, Simpson claimed the church has the right to exclude whomever it wants. He further stated that in accordance with the Constitution, people of the same sex do not currently have the right to marry, and will also not be able to do such an act with the passage of the Bill.
However, Simpson said it is possible that the law, with the passage of the Bill, would have to recognise same-sex domestic partnerships in relation to employment benefits, sharing of properties, etc.
Simpson said he believes there should be a realm of “public” and “private” morality between consenting adults, and implied that the Bill did not fully give “rights” to homosexuals.
But, Nestor interjected: “I am informing you further…that the Sexual Orientation provision has, in fact, in some way recognised the rights of homosexuals and we must accept that.”
Meanwhile, there was no vocal Christian representative(s) at the consultation and apart from the two Opposition representatives none other participant gave comments or directed questions at the presenters.
Other speakers in support of the sexual orientation clause were: Moulana Mohammed Ali Zenjiban, Assistant Director of the International Islamic College; Denuka Radzik from Red Thread, Keimo Benjamin, UG law student and Vidyartha Kissoon from Help & Shelter.
The Sunday Chronicle has been reliably informed that the Georgetown Ministers Fellowship, representing groups of Christian leaders staunchly against sexual orientation as a right in Guyana, have recently prepared a detailed 16-page document outlining issues arising from research to further boost their argument against the inclusion of the clause.
The document is yet to be made public.

Alkaline volcanism associated with early stage of rifting : East African Rift, Tanzania, Manyara basin ; Volcanisme alcalin associé à l'initiation de la rupture continentale : Rift Est Africain, Tanzanie, bassin de Manyara Auteur(s) : Baudouin, Céline Auteurs secondaires : Géosciences Montpellier ; Université des Antilles et de la Guyane (UAG) - Institut national des sciences de l'Univers (INSU - CNRS) - Université de Montpellier (UM) - Centre National de la Recherche Scientifique (CNRS) Université Montpellier Fleurice Parat Christel Tiberi Éditeur(s) : HAL CCSD Résumé : East African Rift (EAR) is the divergent plate boundary. EAR exposes different stages of extension, from early stage rifting in Tanzania to oceanic accretion in Afar (Ethiopia). Manyara basin is the southernmost rift system of the east branch of EAR with recent volcanism (< 1.5 Ma) and a seismic swarm in the lower crust (20 – 40 km). Due to its location and tectonic setting, the Manyara basin offers the opportunity to study the earliest stage of rift initiation. Manyara volcanism is composed of several types of hyper-alkaline lavas as Mg-nephelinites (Mg# > 55) (Labait, Kwaraha), calciocarbonatite (Kwaraha) and evolved nephelinites (Mg# < 35) (Hanang).Mg-nephelinites (Labait and Kwaraha) are primary lavas mainly composed of olivine and clinopyroxene (cpx). Geochemical modelling from trace elements suggests that these primary magmas result from a degree of partial melting < 1 % from a CO2-garnet-phlogopite-bearing peridotite. These magmas have an asthenospheric source at depth > 120 km (lava carries xenoliths with equilibrium conditions > 4 GPa). The minerals were crystallized from a magma with a low H2O content (0.1 and 0.5 wt% H2O). The calciocarbonatite and evolved nephelinites are derived from Mg-nephelinites by fractional crystallization and immiscibility processes. Hanang nephelinites are silica- and alkaline-rich lavas (44.2 – 46.7 wt % SiO2, 9.5 –12.1 wt % Na2O+K2O, respectively) composed by cpx, Ti-garnet, nepheline, apatite and titanite. Complex zonation of cpx (e.g. abrupt change of Mg#, Nb/Ta, and H2O) and trace element patterns of nephelinites record magmatic differentiation involving open system with carbonate-silicate immiscibility and primary melt replenishment. The low H2O content of cpx (3 – 25 ppm wt. H2O) indicates that at least 0.3 wt % H2O was present at depth during carbonate-rich nephelinite crystallization at 340 – 640 MPa and 1050 – 1100 °C. The study of hosted-nepheline melt inclusions from Hanang allows constraining the late magmatic evolution of nephelinites during storage and magma ascent. Melt inclusions are composed by a silicate trachytic glass, a carbonate phase and a shrinkage bubble. Trachytic glass contains high content in CO2 (0.43 wt %, SIMS analyses), sulfur (0.21 – 0.92 wt % S), chlorine (0.28 –0.84 wt % Cl) and H2O low content (< 0.1 wt %, Raman analyses). Immiscibility process leading to the formation of carbonate occurs in a closed system during rapid magma ascent between 200 – 500 MPa. The carbonate phase is a Ca-Na-K-S-rich and anhydrous carbonate (33 wt % CaO, 20 wt % Na2O, 3 wt % K2O, and 3 wt % S). The pre-immiscible liquid has a phonolitic composition with 6 ± 1.5 wt % CO2 at 700 MPa. A preliminary study of melt inclusions by XANES spectroscopy and whole rocks by Mössbauer spectroscopy was used to determine these Manyara lavas were formed at oxidizing conditions (~ ΔFMQ +1.5).The early stage rifting volcanism (Manyara Basin) is characterized by CO2-rich and H2O-poor magmas from at least 120 km below the rift escarpment. The presence of CO2-rich magmas and the small amount of volcanic rocks erupted at the surface may indicate that the storage and percolation of these magmas at depth is a potential trigger for deep seismic swarms. Le rift Est africain (REA) est une frontière de plaque en extension. Ce rift présente plusieurs stades d’extension, de l’initiation du rift en Tanzanie jusqu’à l’accrétion océanique en Afar. Le bassin de Manyara se situe le plus au sud de branche Est du REA. Il est caractérisé par la présence de volcanisme récent (< 1,5 Ma) et d’un essaim sismique dans la croûte inférieure (20 – 40 km). De par sa localisation et son contexte tectonique, le bassin de Manyara offre l’opportunité d’étudier le stade le plus précoce de l’initiation du rift. Le bassin de Manyara est composé de plusieurs types de laves hyperalcalines, les néphélinites magnésiennes (Mg# > 55) (Labait, Kwaraha), de calciocarbonatite (Kwaraha) et des néphélinites différenciées (Mg# < 35) (Hanang).Les néphélinites magnésiennes (Labait et Kwaraha) sont des laves primaires composées d’olivines et de clinopyroxènes (cpx). La modélisation géochimique des éléments en trace suggère que ces magmas primaires résultent d'un degré de fusion partielle ≤ 1 % à partir d'une péridotite à grenat et phlogopite. Ces magmas proviennent d’une profondeur > 120 km (présence de xénolites avec des conditions d’équilibre > 4 GPa). Les minéraux ont cristallisés à partir d’un magma pauvre en eau (0,1 et 0,5 pds % H2O). La calciocarbonatite et les néphélinites différenciés sont issues des néphélinites magnésiennes par cristallisation fractionnée et processus d’immiscibilité. Les néphélinites du Hanang sont riches en éléments alcalins (9,5 – 12,1 pds % Na2O+K2O) et en silice (44,2 – 46,7 pds% SiO2) et sont composés de cpx, grenat, néphéline, titanite et apatite. La zonation complexe dans les cpx (par exemple, changement brusque de Mg#, Nb/Ta, et H2O) implique une différenciation magmatique en système ouvert avec immiscibilité de liquide carbonaté et silicaté ainsi qu’un remplissage de la chambre magmatique avec des liquides primaires. La faible teneur en eau des cpx (3 – 25 ppm H2O) indique la présence d’un magma pauvre en eau (0,3 pds % H2O) lors de la cristallisation des cpx à des conditions crustales (340 – 640 MPa et 1050 – 1100 °C). L’étude des inclusions vitreuses dans les néphélines de Hanang permet de contraindre l'évolution magmatique tardive des néphélinites et le comportement des éléments volatils (CO2, H2O, S, F, Cl) lors du stockage et de la remontée du magma. Les inclusions vitreuses sont composées d’un verre trachytique, d’une phase carbonatée et d’une bulle de rétraction. Le verre trachytique contient du CO2 (0,43 pds % CO2, analyses SIMS), du soufre (0,21 à 0,92 pds% S), du chlore (0,28 – 0,84 pds % Cl) et très peu d’H2O (< 0,1 pds % H2O, analyses Raman). Le processus d’immiscibilité conduisant à la formation du carbonate se produit dans un système fermé pendant l'ascension rapide du magma, entre 200 – 500 MPa. La phase carbonatée est un carbonate anhydre et riche en Ca-Na-K-S (33 pds % CaO, 20 pds % Na2O, 3 pds % K2O, et 3 pds % S). Le liquide pré-immiscible a une composition phonolitique avec 6 ± 1,5 pds % CO2 à une pression de 700 MPa. Une étude préliminaire des inclusions par spectroscopie XANES et des roches par spectroscopie Mössbauer a permis de déterminer que les laves de Manyara se sont formées à conditions oxydantes (~ ∆FMQ +1,5).À l’initiation du rift, le volcanisme dans le bassin de Manyara est caractérisé par des magmas riches en CO2 et pauvres en H2O issus d’au moins 120 km de profondeur sous l'escarpement du rift. La présence de ces magmas riches en CO2 et la faible quantité de roches volcaniques émises à la surface peuvent indiquer que le piégeage et la percolation de ces magmas en profondeur est un déclencheur potentiel des essaims sismiques profonds. https://tel.archives-ouvertes.fr/tel-01563231 NNT : 2016MONTT114 tel-01563231 https://tel.archives-ouvertes.fr/tel-01563231 https://tel.archives-ouvertes.fr/tel-01563231v2/document https://tel.archives-ouvertes.fr/tel-01563231/file/2016_BAUDOUIN_archivage.pdf | Partager |

Service commun de la documentation Extrait de : 52e congrès annuel de la Société caribéenne des plantes alimentaires / 52nd annual meeting of the Caribbean food crops society (CFCS), du 10 au 16 juillet 2016. INRA, CFCS Description : Multiples sont les composantes de l'espace géographique des Caraïbes, (ilots, ilets, iles, archipels, continentale, isthmique), surmultipliées sont les questions, quand est abordé le développement de productions alimentaires ou non- alimentaires à base des ressources locales. Car ces dernières sont très diverses en termes de typologie d'organes, de propriétés d'intérêt à préserver, de disponibilité dans des espaces cultivés ou non, à des strates très variables du couvert végétal ou du sous-sol. Leur valorisation optimale est soumise à la prise en compte du temps en termes de moment et de délais i. e. stade physiologique optimale de récolte et/ou délais de manipulation courts à respecter du fait d'une évolution rapide sous climat tropical chaud et humide. C'est pourquoi, les compétences à intégrer les diverses dimensions de l'objet biologique d'intérêt, de la ressource, sont primordiales aux outils-types proposés par les fournisseurs de technologie. Il est déterminant de façonner des équipements ad hoc, en négociant près des fournisseurs de manière ferme et pointue des besoins et des fonctions. Autrement on prend le risque de recevoir des moyens faits pour un autre monde. Dans une présentation à plusieurs voix nous allons vous faire partager des succès stories, d'opérations ou de transferts de technologie impliquant la mise en ?uvre de plates formes technologiques, obtenues dans des conditions différentes. L'objectif est de mettre en évidence combien il est aussi opportun de maîtriser la phase d'étude de plateforme pilote du processus de développement, d'innovation, pour provoquer le succès.

Demande et Géographie du commerce des mules entre les empires dans la Caraïbe Auteur(s) : Klooster, Wim Année de publication : Loading the player... Éditeur(s) : Université des Antilles AIHP-GEODE : Archéologie Industrielle, Histoire, Patrimoine/Géographie- Développement Environnement de la Caraïbe HARCMAR : Histoire et Archéologie Maritimes des Petites Antilles Extrait de : "Entre exclusif et contrebande, le commerce colonial aux Antilles XVIIe-début XIXe siècle" : journées d'étude, du 24 au 26 octobre 2019. Université des Antilles Description : In the eighteenth and the early nineteenth centuries, inter-imperial connections, many of which were illicit, were of crucial importance in the functioning of European colonialism in the Atlantic world and during its heyday. One example of economically important trade connections across imperial borders is the maritime mule trade. Based on a large variety of secondary sources, supplemented by primary materials, this paper seeks to provide insights into the functioning of this business. Enterprising merchants used the opportunities available to them to connect breeding areas and zones of cash crop production. Likewise, geography played an important role in connecting demand and supply over both short and long distances, as physical proximity and trade winds helped forge connections. Mules were transported to the insular Caribbean, and in particular the French islands, to serve as draft animals, especially by moving vertical cylinders called rollers that crushed the sugar cane, although they were not the only animals used for such purposes. To meet the mule demand of the Caribbean islands, the animals were imported from a variety of regions, including France, North Africa, and the Cape Verde islands. Eventually, however, supplies from other parts of the Greater Caribbean came to dominate the mule business.

The Centro Espanol's "La Benifica" Clinic located on 10th Avenue and 15th Street in Ybor City. Auteur(s) : Robertson and Fresh Photographers, 1925-1960 ( Photographer ) Résumé : Tampa had no existing philanthropic or charitable institutions at the beginning of this immigration wave and, in comparison to other communities, religious institutions played a relatively modest role there. El Centro Español was founded by the Spanish elite who dominated Ybor City, to preserve their identity, provide recreational opportunities and to offer low-cost health care for the many single men and the increasing number of families settling in the area. The club's Sanatorio, completed in 1906, was probably the most modern and complete hospital in Florida at the time.

DESIGN: Multicenter study including all patients notified at the French National Reference Center for Invasive Mycoses and Antifungals. METHODS: Retrospective chart review. Each case was compared with two controls without opportunistic infections. RESULTS: Eighteen cases of cryptococcosis complicating sarcoidosis were analyzed (13 men and 5 women). With 2749 cases of cryptococcosis registered in France during the inclusion period of this study, sarcoidosis accounted for 0.6% of all the cryptococcosis patients and for 2.9% of the cryptococcosis HIV-seronegative patients. Cryptococcosis and sarcoidosis were diagnosed concomitantly in four cases; while sarcoidosis was previously known in 14/18 patients, including 12 patients (67%) treated with steroids. The median rate of CD4 T cells was 145 per mm(3) (range: 55-1300) and not related to steroid treatment. Thirteen patients had cryptococcal meningitis (72%), three osteoarticular (17%) and four disseminated infections (22%). Sixteen patients (89%) presented a complete response to antifungal therapy. After a mean follow-up of 6 years, no death was attributable to cryptococcosis. Extra-thoracic sarcoidosis and steroids were independent risk factors of cryptococcosis in a logistic regression model adjusted with the sex of the patients. CONCLUSIONS: Cryptococcosis is a significant opportunistic infection during extra-thoracic sarcoidosis, which occurs in one-third of the cases in patients without any treatment; it is not associated to severe CD4 lymphocytopenia and has a good prognosis.

Probiotic effect of FLOC on Vibrios in the pacific white shrimp Litopenaeus Vannamei Auteur(s) : Aguilera-rivera, Diana Prieto-davo, Alejandra Escalante, Karla Chavez, Cristina Cuzon, Gerard Gaxiola, Gabriela Éditeur(s) : Elsevier Science Bv Résumé : The advantages of FLOC over clear water (CW) in rearing juvenile L. vannamei and its effects on Vibrio communities were evaluated. Survival rate in FLOC and clear water were recorded and a probiotic was tested under both conditions. Daily growth rate (DGR) was higher in FLOC (p < 0.05) than in CW. Survival in each system increased significantly when a probiotic was included in the diet (p < 0.05). The Vibrionaceae community from the hepatopancreas (HP) and the culture medium did not differ between the two culture media. Nevertheless, a novel group of Vibrio strains was found to be unique to FLOC. No high level of lesions was observed in shrimp tissues from the FLOC + probiotic treatment; it suggests that the probiotic contributed to homeostasis and prevented outbreak of opportunistic pathogenic species.

Fish, fishers, seals and tourists: Economic consequences of creating a marine reserve in a multi-species, multi-activity context Auteur(s) : Boncoeur, Jean Alban, Frederique Guyader, Olivier Thebaud, Olivier Éditeur(s) : Wiley Résumé : This paper investigates some economic consequences of creating a marine reserve on both fishing and ecotourism, when the range of controllability of fishing effort is limited and the impact of the reserve on ecosystem is considered. The issue is illustrated by the example of creating a no-take zone in part of a region where fishing is managed through a limited entry license system, and which is inhabited by two interacting stocks: a stock of prey (fish) and a stock of predators (seals). While the former is targeted by commercial fishing, the latter is not subject to harvest but is a potential basis for a commercial non-extractive activity (seal watching). Analysis is conducted with the help of a bioeconomic model combining the features of marine reserve modeling and of multispecies modeling. Following a description of the model, results of several simulation runs are presented. These show that creating a marine reserve has more complex economic implications than predicted in studies focused exclusively on one stock and/or commercial fisheries. More specifically, the model shows that the dynamics of the two interacting stocks reduces the benefits of the no-take zone for the fishing industry, while it makes the creation of this zone provide an opportunity for the development of ecotourism. Due to this dynamics, the model suggests that the optimal size of the reserve is larger when ecotourism is taken into account along with fishing activities.

Etude d'une gestion optimale des pecheries de langoustine et de poissons demerseaux en mer Celtique. Tome 3 Auteur(s) : Charuau, Anatole Biseau, Alain Charuau, Anatole Biseau, Alain Résumé : All the biological elements obtained in the two first phases of the study and the basical economical data are synthetized in a bio-economical model. From a typology of French fleets fishing in Celtic Sea, the carried out "métiers" (target-species + areas) are pointed out, which allows to define spatio-temporal "boxes". In each compartment, at a given time, the interactive components between fleets and stocks are known. The principle of the model consists to distribute, for each time interval, the fleets in each box. The allocation of fishing effort is assigned by two coefficients : "adherence" and "preference", expressing the abilities of fleets to seize the opportunities. Thus, it is possible to assess the consequences of usual management measures : quotas, mesh size, limitation of fishing effort, etc ... Une synthèse de tous les éléments biologiques acquis précédemment et des données économiques de base est effectuée dans un modèle bio-économique. A partir d'une typologie des flottilles françaises péchant en Mer Celtique, on met en évidence les métiers (espèces + secteurs) pratiqués, ce qui permet de définir des compartiments spatio-temporels dans lesquels on connaît à un moment donné les éléments interactifs entre flottilles et stocks. Le principe du modèle consiste à distribuer, à chaque intervalle de temps les flottilles dans ces compartiments. L'allocation de l'effort est gérée par deux coefficients, adhérence et préférence, qui traduisent les capacités des flottilles à saisir les opportunités. Ainsi, il est possible d'évaluer les conséquences des mesures habituelles de gestion : quotas, maillages, limitation de l'effort, etc...

Underwater acoustics for ecosystem-based management: state of the science and proposals for ecosystem indicators Auteur(s) : Trenkel, Verena Ressler, Patrick H. Jech, Mike Giannoulaki, Marianna Taylor, Chris Éditeur(s) : Inter-research Résumé : Ecosystem-based management (EBM) requires more extensive information than single-species management. Active underwater acoustic methods provide a means of collecting a wealth of ecosystem information with high space-time resolution. Worldwide fisheries institutes and agencies are carrying out regular acoustic surveys covering many marine shelf ecosystems, but these data are underutilized. In addition, more and more acoustic data collected by vessels of opportunity are becoming available. To encourage their use for EBM, we provide a brief introduction to acoustic and complementary data collection methods in the water column, and review current and potential contributions to monitoring population abundance and biomass, spatial distributions, and predator-prey relationships. Further development of acoustics-derived indicators is needed. We review and propose indicators for assessing and monitoring zooplankton, population dynamics of fish and other nekton, and changes in diversity and food-web functioning. Acoustic methods have the potential to make a strong contribution to EBM. Evaluation of new indicators and suitable reference points in different ecosystems are the current challenges.
