The thesis show you seven interpretation models of erosion of MAs1+2 in the west of prospect and eroded gully of middle and east, form the interpretation technique how to built up eroded gully of the Ordovician top, according of the practical demand of oil-gas exploration in the ShanGanNing basin, using seismic information, combining well logging and well drilling data, Carefully analyzing geologic deposition background and well logging data, through a great quantity forward and inversion for geologic model and combination geologic model with seismic section. Related to research of reservoir absorption in the ShanGanNing basin, it firstly introduces PRONY transformation multidimensional filter. It can simultaneously express relationship of frequency and absorption decay coefficient, better than FUSAIPU analysis method; PRONY filter have obtain the better effect in the gas field of ZhenChuanBao in the ShanBei area after adopting PRONY filtering method to predict reservoir absorption, by analyzing fixed well and prediction of non-well drilling. In the ShanGanNing basin, general seismic inversion method can produce evident different results or misunderstanding because wave impedance and lithology, physical property, gas property are not sole, especially while have little impedance contrast and even have contract direction; the author carefully analyzes multi-parameter inversion technique, add natural gamma ray and natural potential and other parameter combined making model inversion method according of theory of seismic inversion and applying reservoir velocity and wave impedance information at last, we get the more directly reservoir physical property parameter, judging reservoir physical property is more exact. In accordance with geologic, seismic feature of Shan basin, the thesis conclude Ordovician system top erosion interpretation technology with ChangQing character, and reservoir thickness prediction technique combining inversion technique with wave character analysis, Reservoir physical property that is mainly absorption factor analysis and multi-parameter inversion and oil-gas prediction technology. These technologies obtain the better result in the oil-gas field exploration and have formed comprehensive research method and technology series with ShanGanNing character.

Prevalence of Asthma Symptoms and Associated Factors in Schoolchildren from Brazilian Amazon Islands

Objectives. To determine the prevalence of asthma symptoms among schoolchildren living on two different Brazilian Amazon islands and to identify the risk factors related to this condition. Methods. A cross-sectional study of 400 schoolchildren (5-8 years old) using written questionnaires produced by the International Study of Asthma and Allergies in Childhood, a skin prick test (allergic sensitization), and a stool examination (for helminthic infection). Nonparametric tests were carried out, and the risk factors were identified by logistic regression. Results. the prevalence of active asthma symptoms was markedly higher in children living on Outeiro Island (OI) than those living on Comb Island (CBI) (30.5% and 16.5%, respectively). the logistic regression identified several risk factors of asthma symptoms on CBI: parental history of asthma, night coughing in the past year, and currently have a cat. On OI, the major risk factors were parental history of asthma, personal history of eczema, having two or more older siblings, and night coughing in the past year. the risk factors in common on both the islands were night coughing in the past year and parental history of asthma. Conclusions. the prevalence of asthma symptoms was higher in those with a lifestyle closer to that observed in urban areas (i.e., better sanitation and hygiene), reinforcing the protective effect of a rural environment. Different risk factors were associated with asthma symptoms in schoolchildren living on OI and on CBI. This fact may reflect the environmental individuality and particularities of each island.

Betha Cholmáin maic Luacháin: an ecclesiastical microcosm of the twelfth-century Irish midlands

Betha Cholmáin maic Luacháin (BCh) is a key source of information about a small ecclesiastical community of the Irish midlands in the medieval period. BCh is one of the longest medieval Irish hagiographic texts. A sole copy exists. Scholarly concern with manuscript Rennes 598, and the Life of Colmán therein, diminished following the 1911 edition of BCh. The most attention paid to BCh in the following decades focused largely on its onomastic information. The necessary detailed study of the text has not been undertaken. The present work is an initial view of significant areas of interaction between the church of Lann and its ecclesiastical, social and political milieu. While social and cultural aspects of the text may constitute the focus of this study, linguistic data is also investigated, complementary to evidence regarding its social and political testimony. In this way, light is cast on a complex ecclesiastical microcosm in the twelfth-century Irish midlands. In keeping with recent methodological work in the field a variety of tools are used to aid investigation, and to show the Life within its genre and wider context. An interdisciplinary approach will bring together strands of literary, cultural, archaeological, onomastic, historical, geographical, genealogical and hagiographical information, with reference to linguistic evidence where appropriate. This thesis seeks to suggest a template for studies undertaken on smaller church communities, and is set out in two main sections. The first section investigates the figure of the saint, his life, church, the manuscript source and the combination of prose and verse in the text. The second section examines the testimony of the Life regarding the ecclesiastical and secular concerns of the community of Lann, and how these concerns are represented. Evidence regarding the members of this community and their interaction with the church and the wider world is also discussed.

Afro-Cuban Bata Drum Aesthetics: Developing Individual and Group Technique, Sound and Identity

The Lucumi religion (also Santeria and Regla de Ocha) developed in 19th-century colonial Cuba, by syncretizing elements of Catholicism with the Yoruba worship of orisha. When fully initiated, santeros (priests) actively participate in religious ceremonies by periodically being possessed or "mounted" by a patron saint or orisha, usually within the context of a drumming ritual, known as a toque de santo, bembe, or tambor. Within these rituals, there is a clearly defined goal of trance possession, though its manifestation is not the sole measure of success or failure. Rather than focusing on the fleeting, exciting moments that immediately precede the arrival of an orisha in the form of a possession trance, this thesis investigates the entire four- to six-hour musical performance that is central to the ceremony. It examines the brief pauses, the moments of reduced intensity, the slow but deliberate build-ups of energy and excitement, and even the periods when novices are invited to perform the sacred bata drums, and places these moments on an equal footing with the more dynamic periods where possession is imminent or in progress. This document approaches Lucumi ritual from the viewpoint of bata drummers, ritual specialists who, during the course of a toque de santo, exercise wide latitude in determining the shape of the event. Known as omo Ana (children of the orisha Ana who is manifest in drums and rhythms), bata drummers comprise a fraternity that is accessible only through ritual initiation. Though they are sensitive to the desires of the many participants during a toque de santo, and indeed make their living by satisfying the expectations of their hosts, many of the drummers' activities are inwardly focused on the cultivation and preservation of this fraternity. Occasionally interfering with spirit possession, and other expectations of the participants, these aberrant activities include teaching and learning, developing group identity or signature sound, and achieving a state of intimacy among the musicians known as "communitas."

Hypoallergenic legume crops and food allergy: factors affecting feasibility and risk.

Currently, the sole strategy for managing food hypersensitivity involves strict avoidance of the trigger. Several alternate strategies for the treatment of food allergies are currently under study. Also being explored is the process of eliminating allergenic proteins from crop plants. Legumes are a rich source of protein and are an essential component of the human diet. Unfortunately, legumes, including soybean and peanut, are also common sources of food allergens. Four protein families and superfamilies account for the majority of legume allergens, which include storage proteins of seeds (cupins and prolamins), profilins, and the larger group of pathogenesis-related proteins. Two strategies have been used to produce hypoallergenic legume crops: (1) germplasm lines are screened for the absence or reduced content of specific allergenic proteins and (2) genetic transformation is used to silence native genes encoding allergenic proteins. Both approaches have been successful in producing cultivars of soybeans and peanuts with reduced allergenic proteins. However, it is unknown whether the cultivars are actually hypoallergenic to those with sensitivity. This review describes efforts to produce hypoallergenic cultivars of soybean and peanut and discusses the challenges that need to be overcome before such products could be available in the marketplace.

Delimiting species without nuclear monophyly in Madagascar's mouse lemurs.

BACKGROUND: Speciation begins when populations become genetically separated through a substantial reduction in gene flow, and it is at this point that a genetically cohesive set of populations attain the sole property of species: the independent evolution of a population-level lineage. The comprehensive delimitation of species within biodiversity hotspots, regardless of their level of divergence, is important for understanding the factors that drive the diversification of biota and for identifying them as targets for conservation. However, delimiting recently diverged species is challenging due to insufficient time for the differential evolution of characters--including morphological differences, reproductive isolation, and gene tree monophyly--that are typically used as evidence for separately evolving lineages. METHODOLOGY: In this study, we assembled multiple lines of evidence from the analysis of mtDNA and nDNA sequence data for the delimitation of a high diversity of cryptically diverged population-level mouse lemur lineages across the island of Madagascar. Our study uses a multi-faceted approach that applies phylogenetic, population genetic, and genealogical analysis for recognizing lineage diversity and presents the most thoroughly sampled species delimitation of mouse lemur ever performed. CONCLUSIONS: The resolution of a large number of geographically defined clades in the mtDNA gene tree provides strong initial evidence for recognizing a high diversity of population-level lineages in mouse lemurs. We find additional support for lineage recognition in the striking concordance between mtDNA clades and patterns of nuclear population structure. Lineages identified using these two sources of evidence also exhibit patterns of population divergence according to genealogical exclusivity estimates. Mouse lemur lineage diversity is reflected in both a geographically fine-scaled pattern of population divergence within established and geographically widespread taxa, as well as newly resolved patterns of micro-endemism revealed through expanded field sampling into previously poorly and well-sampled regions.

Rapamycin Interferes With Postdepletion Regulatory T Cell Homeostasis and Enhances DSA Formation Corrected by CTLA4-Ig.

Previously, we demonstrated that alemtuzumab induction with rapamycin as sole maintenance therapy is associated with an increased incidence of humoral rejection in human kidney transplant patients. To investigate the role of rapamycin in posttransplant humoral responses after T cell depletion, fully MHC mismatched hearts were transplanted into hCD52Tg mice, followed by alemtuzumab treatment with or without a short course of rapamycin. While untreated hCD52Tg recipients acutely rejected B6 hearts (n = 12), hCD52Tg recipients treated with alemtuzumab alone or in conjunction with rapamycin showed a lack of acute rejection (MST > 100). However, additional rapamycin showed a reduced beating quality over time and increased incidence of vasculopathy. Furthermore, rapamycin supplementation showed an increased serum donor-specific antibodies (DSA) level compared to alemtuzumab alone at postoperation days 50 and 100. Surprisingly, additional rapamycin treatment significantly reduced CD4(+) CD25(+) FoxP3(+) T reg cell numbers during treatment. On the contrary, ICOS(+) PD-1(+) CD4 follicular helper T cells in the lymph nodes were significantly increased. Interestingly, CTLA4-Ig supplementation in conjunction with rapamycin corrected rapamycin-induced accelerated posttransplant humoral response by directly modulating Tfh cells but not Treg cells. This suggests that rapamycin after T cell depletion could affect Treg cells leading to an increase of Tfh cells and DSA production that can be reversed by CTLA4-Ig.

Adjuvant portal-vein infusion of fluorouracil and heparin in colorectal cancer: A randomised trial

Background. There is conflicting evidence on the efficacy of regional adjuvant chemotherapy, via portal-vein infusion (PVI), after resection of colorectal cancer. We undertook a randomised controlled multicentre trial to investigate the efficacy of PVI (500 mg/m2 fluorouracil plus 5000 IU heparin daily for 7 days). Methods. 1235 of about 1500 potentially eligible patients were randomly assigned surgery plus PVI or surgery alone (control). The patients were followed up for a median of 63 months, with yearly screening for recurrent disease. The primary endpoint was survival; analyses were by intention to treat. Findings. 619 patients in the control group and 616 in the PVI group met eligibility criteria. 164 (26%) control-group patients and 173 (28%) PVI-group patients died. 5-year survival did not differ significantly between the groups (73 vs 72%; 95% CI for difference -6 to 4). The control and PVI groups were also similar in terms of disease-free survival at 5 years (67 vs 65%) and the number of patients with liver metastases (79 vs 77%). Interpretation. PVI of fluorouracil, at a dose of 500 mg/m2 for 7 days, cannot be recommended as the sole adjuvant treatment for high-risk colorectal cancer after complete surgical excision. However, these results cannot eliminate a small benefit when PVI is used at a higher dosage or in combination with mitomycin.

Spin three gauge theory revisited

We study the problem of consistent interactions for spin-3 gauge fields in flat spacetime of arbitrary dimension 3$">n>3. Under the sole assumptions of Poincaré and parity invariance, local and perturbative deformation of the free theory, we determine all nontrivial consistent deformations of the abelian gauge algebra and classify the corresponding deformations of the quadratic action, at first order in the deformation parameter. We prove that all such vertices are cubic, contain a total of either three or five derivatives and are uniquely characterized by a rank-three constant tensor (an internal algebra structure constant). The covariant cubic vertex containing three derivatives is the vertex discovered by Berends, Burgers and van Dam, which however leads to inconsistencies at second order in the deformation parameter. In dimensions 4$">n>4 and for a completely antisymmetric structure constant tensor, another covariant cubic vertex exists, which contains five derivatives and passes the consistency test where the previous vertex failed. © SISSA 2006.

Constructive trusts, illegal purpose and locus poenitentiae

Analyses the Family Division decision in Q v Q on the competing claims of a father and son to beneficial ownership of a house in which the father sought to on a secret agreement entered into with his sons when transferring the property into their joint names, intended to subvert the inheritance tax rules on lifetime gifts by retaining the right to have the property transferred back to him, and the son relied on a later agreement with his brother to transfer the house into his sole name, in reliance on which he and his wife had acted to their detriment by paying for its upkeep and renovation.

No more nonsense

Discusses the approach of the courts to the quantification of beneficial interests in the family home in the event of a relationship breakdown. Assesses the clarification provided by the Court of Appeal ruling in Fowler v Barron on whether the respondent was the sole beneficial owner of a property purchased with his former partner, by means of a significant cash contribution from him and a mortgage in both their names, focusing on whether he could rebut the presumption that they held the property as joint tenants in equity where it was registered in joint names.

Back to the bad old days?

Reviews the Court of Appeal decision in James v Thomas that a cohabitee had not acquired an equitable interest in a property registered in her former partner's sole name through a constructive trust, based on express or inferred common intention, or by proprietary estoppel. Highlights the inconsistent approach of the courts to cohabitee disputes. Outlines the Law Commission's proposals in its 2007 report, Cohabitation: The Financial Consequences of Relationship Breakdown, notes the factors to be taken into account by the courts, and speculates on the case's outcome if the proposals were applied.
