Le grand nymphée de Leptis Magna : étude historiographique, urbanistique et architecturale

RESUME en français Centrée sur le grand nymphée de Leptis Magna la recherche met en évidence l'évolution et la signification de ce monument des eaux dans l'une des plus importantes cités africaines de l'époque romaine en mettant en lumière trois thèmes principaux. L'étude historiographique permet tout d'abord d'appréhender, à l'aide des témoignages littéraires des siècles derniers et d'une abondante documentation d'archive, l'histoire de l'édifice de son ensablement à sa remise au jour, puis de suivre les différentes étapes de son dégagement et de sa restauration, mettant ainsi en relief la perception des divers observateurs à l'encontre du monument. L'étude urbanistique permet ensuite de dégager la signification de l'édifice dans la cité par rapport aux autres monuments du secteur aux différentes périodes de son histoire, ainsi que de reconstituer l'approvisionnement en eau de Leptis Magna. Enfin, l'étude architecturale s'intéresse à l'analyse détaillée des structures, permettant la mise en évidence de la conception initiale, du fonctionnement et des transformations du nymphée. Cette dernière approche, qui s'accompagne d'un catalogue circonstancié des éléments du décor, fait intervenir des considérations sur les techniques de constructions, le traitement des blocs d'ornementation et, d'une manière plus générale, sur ('économie du chantier. Cette recherche permet non seulement de reconstituer l'aspect, le rôle et l'histoire du monument et de le replacer dans la série des nymphées romains, mais aussi de percevoir son impact sur les habitants du lieu aux différents moments de son histoire, cherchant ainsi à rejoindre par l'archéologie des considérations sociologiques. THE GREAT SEVERAN NYMPHAEUM OF LEPTIS MAGNA: HISTORIOGRAPHICAL, URBANISTIC AND ARCHITECTURAL STUDY RESUME en anglais Based on the great nymphaeum of Leptis Magna, the research considers the development and significance of this water monument in one of the most important African cities of the Roman period, through three principal aspects. The historiographical study aboards the subject through literary testimony from the last centuries and an abundance of documentary archives, the history of the edifice from its burial to its reconstruction, studying the different stages of its unearthing and its restoration, thus pinpointing perspectives from various observers of the monument. The urban study divulges the significance of the edifice in the city, in comparison with other monuments in the region over different periods of its history, as well as reconstituting Leptis Magna's water supply. Finally, the architectural study undertakes a detailed analysis of the structures, which highlights the conception and the transformations of the nymphaeum, as well as its hydraulic functions. This architectural approach, which is accompanied by a detailed catalogue of the decorative elements, juxtaposes the technical considerations of construction with the ornamental treatment of the marble blocks, accounting for the economical aspects of the site of the nymphaeum. This research proposes not only a consideration of the appearance, the role and the history of the monument and situates it within the series of Roman nymphaea, but also the perception of its impact on the local inhabitants at different moments in its history, looking for accomplish by archaeology some sociological considerations.

Selvitys Eduskunnan lisärakennuksen taidekilpailusta

The purpose of this thesis was to investigate how and why an art competition was arranged to select pieces for the parliamentary annexe building in Helsinki. There is an emphasis on the cultural production aspects of the research. For the purpose of comparison, the thesis also examines how art acquisition takes place in the cities of Helsinki, Salo and Vantaa, and how the so-called percentage principle has been used in these cities The research method involved thematic interviewing of four persons with central positions on the competition jury. Questions were also sent by e-mail to experts and other people with knowledge of the subject area. Although art competitions have been arranged in Finland for decades, very little relevant literature exists. In addition to the interviews, other relevant literature was also referred to, including parliamentary records. The crucial questions concerned why the art competition for the parliamentary annexe was arranged and whether, indeed, it is possible to compete artistically in this manner. The thesis also examined the relationship between art and architecture and how the best works were selected from the vast range of submissions. The answers were both honest and interesting. The thesis presents a step-by-step analysis of the competition's progress over two stages, and according to the specific rules for such competitions as laid out in Suomen Taiteilijaseura. Strict adherence to the rules of the competition created a number of problems, some of which are also studied. The primary reason for staging a competition was to be as democratic as possible, and eliminating any possibility of nominating a particular artist or artists to realise their own work within the annexe. The competition opened up the possibility to consider various artistic proposals, and no genres were ruled out in advance. This format ensured a good response and a total of 1719 proposals were received, of which six were eventually selected. One conclusion was that open competition may not be the best way to gather artistic proposals in such circumstances, but it is very democratic.

Daptomycin for highly resistant Enterococcus faecium infection.

We report a case series of 11 patients with severe E. faecium infections treated with daptomycin. All strains were resistant to ampicillin (MIC >8 mg/l), but susceptible to vancomycin. Seven out of 11 strains were also highly resistant to gentamicin (MIC >500 mg/l). All patients were treated with multiple broad-spectrum antibiotics prior to isolation of E. faecium and had severe underlying diseases. Our experience suggests that salvage therapy with daptomycin might be a safe and efficacious treatment for E. faecium infections.

Comunidade de Euglossini (Hymenoptera, Apidae) das dunas litorâneas do Abaeté, Salvador, Bahia, Brasil

Community of Euglossini (Hymenoptera, Apidae) from the coastal sand dunes of Abaeté, Salvador, Bahia, Brazil. The Euglossini community structure was analyzed by attracting males with the scents eucalyptol, eugenol, vanillin, benzyl benzoate and methyl salicylate, and by netting bees on flowers. The samplings took place three times a month along one year from 6:00 a.m. to 6:00 p.m. The scent baits attracted 670 individuals belonging to seven species of three genus. The predominant species were Euglossa cordata (Linnaeus, 1758) (76.6%) and Eulaema nigrita Lepeletier, 1841 (21.8%). Euglossini males visited the scents along the whole year, being more abundant in May and in August. The most efficient fragrance was eucalyptol, attracting 624 individuals of five species. The males abundance fluctuated along the day, being the highest frequency observed between 8:00 a.m. to 10:00 a.m. Forty eigth Euglossini females of four species were netted visiting flowers of 14 plant species belonging to 13 families. Solanaceae and Caesalpiniaceae were the most visited. The species catched on flowers were Euglossa cordata, Eulaema nigrita, Euplusia mussitans (Fabricius, 1787) and Eulaema meriana flavescens Friese 1899. Euglossa cordata was the predominant species on flowers (64.6%), being collected during almost the whole year. Euplusia mussitans was the only species netted on flowers which males were not sampled on the scents.

Primary cutaneous posttransplant lymphoproliferative disorders in solid organ transplant recipients: a multicenter European case series.

Primary cutaneous posttransplant lymphoproliferative disorders (PTLD) are rare. This retrospective, multicenter study of 35 cases aimed to better describe this entity. Cases were (re)-classified according to the WHO-EORTC or the WHO 2008 classifications of lymphomas. Median interval between first transplantation and diagnosis was 85 months. Fifty-seven percent of patients had a kidney transplant. Twenty-four cases (68.6%) were classified as primary cutaneous T cell lymphoma (CTCL) and 11 (31.4%) as primary cutaneous B cell PTLD. Mycosis fungoides (MF) was the most common (50%) CTCL subtype. Ten (90.9%) cutaneous B cell PTLD cases were classified as EBV-associated B cell lymphoproliferations (including one plasmablastic lymphoma and one lymphomatoid granulomatosis) and one as diffuse large B cell lymphoma, other, that was EBV-negative. Sixteen (45.7%) patients died after a median follow-up of 19.5 months (11 [68.8%] with CTCL [6 of whom had CD30(+) lymphoproliferative disorders (LPD)] and 5 [31.2%] with cutaneous B cell PTLD. Median survival times for all patients, CTCL and cutaneous B cell PTLD subgroups were 93, 93, and 112 months, respectively. Survival rates for MF were higher than those for CD30(+) LPD. The spectrum of primary CTCL in organ transplant recipients (OTR) is similar to that in the general population. The prognosis of posttransplant primary cutaneous CD30(+) LPD is worse than posttransplant MF and than its counterpart in the immunocompetent population. EBV-associated cutaneous B cell LPD predominates in OTR.

Chrysomya albiceps (Wiedemann) and Hemilucilia segmentaria (Fabricius) (Diptera, Calliphoridae) used to estimate the postmortem interval in a forensic case in Minas Gerais, Brazil

ABSTRACT. Chrysomya albiceps (Wiedemann) and Hemilucilia segmentaria (Fabricius) (Diptera, Calliphoridae) used to estimate the postmortem interval in a forensic case in Minas Gerais, Brazil. The corpse of a man was found in a Brazilian highland savanna (cerrado) in the state of Minas Gerais. Fly larvae were collected at the crime scene and arrived at the laboratory three days afterwards. From the eight pre-pupae, seven adults of Chrysomya albiceps (Wiedemann, 1819) emerged and, from the two larvae, two adults of Hemilucilia segmentaria (Fabricius, 1805) were obtained. As necrophagous insects use corpses as a feeding resource, their development rate can be used as a tool to estimate the postmortem interval. The post-embryonary development stage of the immature collected on the body was estimated as the difference between the total development time and the time required for them to become adults in the lab. The estimated age of the maggots from both species and the minimum postmortem interval were four days. This is the first time that H. segmentaria is used to estimate the postmortem interval in a forensic case.

Sarcophagidae and Calliphoridae related to Rhinella schneideri (Anura, Bufonidae), Bothrops moojeni (Reptilia, Serpentes) and Mabuya frenata (Reptilia, Lacertilia) carcasses in Brasília, Brazil

Sarcophagidae and Calliphoridae related to Rhinella schneideri (Anura, Bufonidae), Bothrops moojeni (Reptilia, Serpentes) and Mabuya frenata (Reptilia, Lacertilia) carcasses in Brasília, Brazil. This paper presents a list of necrophagous insects associated with small size carrions of two reptiles and one amphibian, found in areas of riparian forests and Cerrado sensu stricto physiognomies in a Conservation Unit located in Brasilia, Distrito Federal. We found seven species of insects related to these carcasses, being five Sarcophagidae, one Calliphoridae and one Braconidae parasitoid wasp. Lucilia eximia and Peckia (Pattonella) intermutans were the most abundant species in the study, corroborating with other studies that suggests that these species have specializations for colonization of small size animal carcasses.

Necrophagous diptera associated with wild animal carcasses in southern Brazil

Necrophagous Diptera associated with wild animal carcasses in southern Brazil. The aim of this study was to acquire a better knowledge concerning the diversity of necrophagous Diptera that develop on wild animal carcasses. For this purpose, the decomposition of six wild animal carcasses was observed in order to collect and identify the main species of necrophagous flies associated with the decomposition process. The carcasses were found on highways near the cities of Pelotas and Capão do Leão in the initial stage of decomposition, with no significant injuries or prior larval activity. Four wild animal models were represented in this study: two specimens of Didelphis albiventris Lund, 1840; two Tupinambis merianae Linnaeus, 1758; one Nothura maculosa Temminck, 1815; and one Cerdocyon thous Linnaeus, 1766. A total of 16,242 flies from 14 species were reared in the laboratory, where Muscidae presented the greatest diversity of necrophagous species. Overall, (i) carcasses with larger biomass developed a higher abundance of flies and (ii) the necrophagous community was dominated by Calliphoridae, two patterns that were predicted from published literature; and (iii) the highest diversity was observed on the smaller carcasses exposed to the lowest temperatures, a pattern that may have been caused by the absence of the generalist predator Chrysomya albiceps (Wiedemann, 1819). (iv) An UPGMA analysis revealed a similar pattern of clusters of fly communities, where the same species were structuring the groupings.

Does Bt maize cultivation affect the non-target insect community in the agro ecosystem?

ABSTRACT The cultivation of genetically modified crops in Brazil has led to the need to assess the impacts of this technology on non-target species. Under field conditions, the potential effect on insect biodiversity was evaluated by comparing a homogeneous corn field with conventional and transgenic maize, expressing different Bt proteins in seven counties of Minas Gerais, Brazil. The richness pattern of non-target insect species, secondary pests and natural enemies were observed. The results do not support the hypothesis that Bt protein affects insect biodiversity. The richness and diversity data of insects studied were dependent on the location and other factors, such as the use of insecticides, which may be a major factor where they are used.

Religious beliefs in schizophrenia: Their relevance for adherence to treatment

The study examined how religious beliefs and practices impact upon medication and illness representations in chronic schizophrenia. One hundred three stabilized patients were included in Geneva's outpatient public psychiatric facility in Switzerland. Interviews were conducted to investigate spiritual and religious beliefs and religious practices and religious coping. Medication adherence was assessed through questions to patients and to their psychiatrists and by a systematic blood drug monitoring. Thirty-two percent of patients were partially or totally nonadherent to oral medication. Fifty-eight percent of patients were Christians, 2% Jewish, 3% Muslim, 4% Buddhist, 14% belonged to various minority or syncretic religious movements, and 19% had no religious affiliation. Two thirds of the total sample considered spirituality as very important or even essential in everyday life. Fifty-seven percent of patients had a representation of their illness directly influenced by their spiritual beliefs (positively in 31% and negatively in 26%). Religious representations of illness were prominent in nonadherent patients. Thirty-one percent of nonadherent patients and 27% of partially adherent patients underlined an incompatibility or contradiction between their religion and taking medication, versus 8% of adherent patients. Religion and spirituality contribute to shaping representations of disease and attitudes toward medical treatment in patients with schizophrenia. This dimension should be on the agenda of psychiatrists working with patients with schizophrenia.

Gene expression signatures delineate biological and prognostic subgroups in peripheral T-cell lymphoma

Peripheral T-cell lymphoma (PTCL) encompasses a heterogeneous group of neoplasms with generally poor clinical outcome. Currently 50% of PTCL cases are not classifiable: PTCL-not otherwise specified (NOS). Gene-expression profiles on 372 PTCL cases were analyzed and robust molecular classifiers and oncogenic pathways that reflect the pathobiology of tumor cells and their microenvironment were identified for major PTCL-entities, including 114 angioimmunoblastic T-cell lymphoma (AITL), 31 anaplastic lymphoma kinase (ALK)-positive and 48 ALK-negative anaplastic large cell lymphoma, 14 adult T-cell leukemia/lymphoma and 44 extranodal NK/T-cell lymphoma that were further separated into NK-cell and gdT-cell lymphomas. Thirty-seven percent of morphologically diagnosed PTCL-NOS cases were reclassified into other specific subtypes by molecular signatures. Reexamination, immunohistochemistry, and IDH2 mutation analysis in reclassified cases supported the validity of the reclassification. Two major molecular subgroups can be identified in the remaining PTCL-NOS cases characterized by high expression of either GATA3 (33%; 40/121) or TBX21 (49%; 59/121). The GATA3 subgroup was significantly associated with poor overall survival (P = .01). High expression of cytotoxic gene-signature within the TBX21 subgroup also showed poor clinical outcome (P = .05). In AITL, high expression of several signatures associated with the tumor microenvironment was significantly associated with outcome. A combined prognostic score was predictive of survival in an independent cohort (P = .004).

Upland rice under no-tillage preceded by crops for soil cover and nitrogen fertilization

The grain yield of upland rice under no-tillage has been unsatisfactory and one reason could be the nitrate/ammonium balance in the soil. Cover crops and nitrogen fertilization can be used to change the nitrate/ammonium relation in the soil and improve conditions for the development of upland rice in the no-tillage (NT) system. The aim was to study the effect of cover crops and nitrogen sources on grain yield of upland rice under no tillage. The study was carried out on the Fazenda Experimental Lageado, in Botucatu, State of São Paulo, Brazil, in an Oxisol area under no-tillage for six years. The experiment was arranged in a randomized block split-plot design with four replications. The plots consisted of six cover crop species (Brachiaria brizantha, B. decumbens, B. humidicola, B. ruziziensis, Pennisetum americanum, and Crotalaria spectabilis) and the split-plots of seven forms of N fertilizer management. Millet is the best cover crop to precede upland rice under NT. The best form of N application, as nitrate, is in split rates or total rate at topdressing or an ammonium source with or without a nitrification inhibitor, in split doses. When the cover crops C. spectabilis, B. brizantha, B. decumbens, B. humidicola, and B. ruziziensis preceded rice, they induced the highest grain yield when rice was fertilized with N as ammonium sulfate source + nitrification inhibitor in split rates or total dose at topdressing.

Daytime sleepiness and the COMT val158met polymorphism in patients with Parkinson disease.

STUDY OBJECTIVE: A preliminary study by our group suggested an association between daytime sleepiness and the catechol-O-methyltransferase (COMT) val158met polymorphism (rs4680) in patients with Parkinson disease (PD). We sought to confirm this association in a large group of patients with PD. DESIGN: Genetic association study in patients with PD. SETTING: Movement disorder sections at 2 university hospitals. PARTICIPANTS: PD patients with and without episodes of suddenly falling asleep matched for antiparkinsonian medication, disease duration, sex, and age, who participated in a previous genetic study on dopamine-receptor polymorphisms. INTERVENTIONS: Not applicable. MEASUREMENTS AND RESULTS: In this study, 240 patients with PD (154 men; age 65.1 +/- 6.1 years; disease duration 9.4 +/- 6.0 years) were included. Seventy had the met-met (LL), 116 the met-val (LH), and 54 the val-val (HH) genotype. In the combined LL+LH group (featuring reduced COMT activity), the mean Epworth Sleepiness Scale (ESS) score was 9.0 +/- 5.9 versus 11.0 +/- 6.1 in the HH (high COMT activity) group (P = .047). Forty-seven percent of the LL and LH patients had sudden sleep onset compared with 61% of the HH patients (P = .07). Logistic regression, however, showed that both pathologic ESS scores (i.e., > 10) and sudden sleep onset were predicted by subjective disease severity (P < .001 each) but not by the COMT genotype. CONCLUSIONS: Our previous finding that the L-allele may be associated with daytime sleepiness could not be confirmed in the present study. Altogether, our data do not support a clinically relevant effect of the COMT genotype on daytime sleepiness in PD.
