Rapid continuous chemical analysis of meat chicken shed emissions by SIFT–MS

Assessing and addressing odour impacts from poultry production is extremely difficult and subjective because the odorants involved and their dynamics over time and space are poorly understood. This knowledge gap is due, in part, to the lack of suitable analytical tools for measuring and monitoring odorants in the field. The emergence of Selected Ion Flow Tube – Mass Spectrometry (SIFT–MS) and similar instruments is changing that. These tools can rapidly quantify targeted odorants in ambient air in real time, even at very low concentrations. Such data is essential for developing better odour abatement strategies, assessment methods and odour dispersion models. This project trialled a SIFT–MS to determine its suitability for assessing the odorants in meat chicken shed emissions over time and space. This report details evaluations in New Zealand and Australia to determine the potential of SIFT–MS as a tool for the chicken meat industry, including odour measurement (as a proxy for dynamic olfactometry). The report is specifically targeted at those funding and conducting poultry odour research. It will be of interest to those involved with environmental odour monitoring and assessment in general. The high upfront cost of SIFT–MS will lead to potential users wanting compelling evidence that SIFT–MS will meet their needs before they invest in one.

La pêche dans le eaux douces du Cambodge

The importance of water in Cambodia's economy has always greatly impressed scientists and their work. This trend is spread over a period of more than 70 years. There were three distinct phases in the history of fishing and fish research in Cambodia. The phase of isolated workers (1865-1923), the phase of the first gathered researches, corresponding to the beginning of the work of the Oceanographic Institute of Indochina (1923-1936), and finally close cooperation phase between the Institute Oceanographic and Protectorate, inaugurated in 1936. The purpose of this 5th Memoire is exposing the knowledge on fishing activities in Cambodia in 1936.

High alkaline phosphatase activity in phosphate replete waters: The case of two macrotidal estuaries

The occurrence of alkaline phosphatase activity (APA) that hydrolyses organic phosphorus into phosphate (PO4) is commonly related to PO4 deficiency of oceanic, coastal and fresh waters. APA is almost never investigated in PO4-rich estuaries, since very low activities are expected to occur. As a consequence, microbial mineralization of organic phosphorus into PO4 has often been ignored in estuaries. In this study, we examined the importance of potential APA and the associated microbial dynamics in two estuaries, the Aulne and the Elorn (Northwestern France), presenting two different levels of PO4 concentrations. Unexpected high potential APA was observed in both estuaries. Values ranged from 50 to 506 nmol L−1 h−1, which range is usually found in very phosphorus-limited environments. High potential APA values were observed in the oligohaline zone (salinity 5–15) in spring and summer, corresponding to a PO4 peak and a maximum bacterial production of particle-attached bacteria. In all cases, high potential APA was associated with high suspended particulate matter and total particulate phosphorus. The low contribution of the 0.2–1 μm fraction to total APA, the strong correlation between particulate APA and bacterial biomass, and the close relationship between the production of particle-attached bacteria and APA, suggested that high potential APA is mainly due to particle-attached bacteria. These results suggest that the microbial mineralization of organic phosphorus may contribute to an estuarine PO4 production in spring and summer besides physicochemical processes.

A rare benign ovarian tumour

Sclerosing stromal tumour (SST) of the ovary is an extremely rare and benign ovarian neoplasm, accounting for 6% of the sex cord stromal ovarian tumours subtype. Usually, it is found during the second and third decades of life. Patients commonly present with pelvic pain, a palpable pelvic mass or menstrual irregularity. We report a case of a 20-year-old woman reporting of mild pelvic pain, with normal laboratory data. On imaging examinations, a large right adnexal tumour was found, with features suggesting an ovarian sex cord tumour. The patient underwent right salpingo-oophorectomy, diagnosing a SST of the ovary. This paper also reviews the literature, and emphasises the typical pathological and imaging characteristics of these rare benign ovarian lesions, and their impact, in a conservative surgery.

Primary lymphomas of the female genital tract: imaging findings

Primary lymphomas of the female genital tract are extremely rare, and a definitive diagnosis requires correlation of the clinical, radiological, and pathological findings. Unlike nonlymphomatous malignant tumors, the treatment of lymphoma is typically nonsurgical, thus raising the possibility of lymphoma in the differential diagnosis of a pelvic mass, a radiologist can significantly change the approach to the disease. Although some imaging findings may appear nonspecific, others may suggest the possibility of lymphoma, such as the presence of one or more solid, well-defined, homogeneous masses without necrosis despite a large size or the presence of diffuse infiltration leading to organomegaly with architectural preservation. Additionally, pelvic lymphadenopathy may be evident. In this pictorial essay, we discuss the radiological appearances of gynecological primary lymphomas, grouped by organ, in ultrasonography, computed tomography, and magnetic resonance imaging.

In Praise of Library History

This article marks the decline of the historical study of the Library meet the increase in studies on technology-driven globalization and the predominance of technicality in the discipline, but it is essential to return to that historical knowledge if the Library want instituted as a fully scientific field of knowledge. Emphasized in the beginning of the Library from orality to the written record preserved by the archives and libraries and its close relation to the development of the science of history. It also establishes the link between documents librarians and historians to understand the past and present society.

A cultura de índio, seu menino, vem de longe aqui : formação histórica e territorialização dos Tremembé/CE

This dissertation is based on the ethnography of a strategic selection of three Tremembé ethnic situations, which are situated in the backlands of Acaraú and Itarema, municipalities located in Ceará State (Northeast Brazil). My main aims are the following. Firstly, I reconstitute the historical and social formation of three localities, called Lagoa dos Negros, Telhas, and Queimadas, related to a particular origin myth which refers to Almofala, an extinct colonial Aldeamento in the seashore, where the Tremembé indians and other native populations were converted and gathered under missionary administration. According to the origin myth, these three localities were set up after a strong drought which happened in 1888 (the so called three eights) when a group of Tremembé families moved to the countryside and established close to the Lagoa dos Negros and, later on, they were segmented into smaller groups which started to live in other areas and places not far from the former location. Notably, I develop an anthropological approach to understand the historical formation of these three localities. Secondly, I analyze some processes of territorialization, which were emerged from the 1980s and had important consequences to these indigenous families throughout the next two decades. This historical dimension is re-appropriated and ressignified in ethnic terms. A third point of my work is the analysis of the construction of territorialities and also the cultural and symbolic dimensions which are formulated by the Tremembé Indians who live in these localities. Therefore, I investigate some cultural traditions and rituals, such as the Torém dance, but I also examine their multiple semantics, which constitute a transversal direction throughout the history understood by the Tremembé of the different social situations I researched. To sum up, there is a process of cultural actualization, which is still going on and presents itself through the ludic sphere as well as their political and religions dimensions, which are usually associated to the ritual presentation of the Torém

A internacionalização de empresas portuguesas para Cabo Verde : investimento directo e as estratégias competitivas

A presente investigação procura estudar a internacionalização das empresas portuguesas para Cabo Verde, através de investimento direto, e as estratégias competitivas que elas adotaram. Na sequência da revisão da literatura, a fim de obter respostas para a pergunta de pesquisa, analisamos a internacionalização das empresas portuguesas, a sua evolução, o investimento português no estrangeiro, e a evolução dos fluxos do Investimento Direto Estrangeiro (IDE) em Cabo Verde, a partir de dados estatísticos recolhidos na literatura publicada. De seguida foram recolhidos dados primários, através da aplicação de dois questionários direcionados para o mercado cabo-verdiano (clientes) e empresas portuguesas que investiram em Cabo Verde. A amostra é constituída por 157 clientes, 77 do sexo feminino e 80 do sexo masculino, e a outra amostra é constituída por 10 empresas portuguesas que investiram em Cabo Verde através de Investimento Direto. Os resultados do presente estudo mostram que a estratégia de adaptação não contribuiu significativamente para melhorar a opinião do mercado cabo-verdiano sobre as marcas portuguesas e que, as empresas adaptaram naquele mercado principalmente as variáveis distribuição e preço. As empresas portuguesas podem seguir estratégias de padronização do produto e da promoção/comunicação, precisando apenas adaptar o preço aos diferentes fatores de custo e a distribuição à natureza insular do mercado. Concluímos que, de uma forma geral, a proximidade cultural, geográfica e histórica entre os dois países é responsável pela não necessidade da estratégia de adaptação por parte das empresas portuguesas quando internacionalizam para Cabo Verde. /ABSTRACT: The present investigation aims to study the internationalization of portuguese companies to Cape Verde, through direct investment, and their competitive strategies. Following the literature review, in order to answer the research question, the internationalization of Portuguese companies was analyzed, as was the Portuguese investment abroad, and the evolution of Foreign Direct Investment (FDI) flows in Cape Verde, with statistical data collected from the literature. Primary data was collected through the use of two questionnaires directed to the Cape Verdean market (customers) and to the Portuguese companies that have invested in Cape Verde. The sample consists of 157 customers, 77 females and 80 males, and the other sample consists of 10 Portuguese companies that have invested in Cape Verde through Direct Investment. The results of this study show that the adaptation strategy did not help improve Cape Verdean market's opinion about the Portuguese brands, and those, companies adapted primarily the distribution and price variables. The Portuguese companies can follow standardization strategies of the product and the promotion I communication, just needing to adjust the price to the various cost factors and the distribution to the insular nature of the market. We conclude that, in general, the cultural, historic and geographical proximity and the close relationship between the two countries lessens the necessity of adaptation strategy by the Portuguese companies when they internationalize to Cape Verde.

Regionen och EU? : Uppfattningar och attityder till EU-relaterade frågor i Västsverige

This thesis explores perceptions and preferences on regional action in EU-related frameworks among regional actors in Western Sweden. Building upon the literature on Europeanisation and the Fusion approach, three dimensions of Europeanisation are clarified and explored– download, upload and crossload – and together with a set of five variables that constitute the Micro Fusion Framework; a comprehensive analytical tool is developed. The thesis analyses the intense debate among the members of West Sweden that took place from 2011 to 2013 that focused on how to functionally organise the regional office in Brussels in order to meet future challenges. Surprisingly, the members eventually decided to terminate their cooperation and close the jointly owned office in Brussels in spite of the fact that it has been widely regarded as successful and effective. Diverging perceptions and preferences is understood in terms of three positions on regional action; a download-, upload- and a coherent oriented position. Finally, the thesis presents the empirical findings and discusses in relation to three fusion scenarios, infusion, defusion and clustered fusion. In terms of Micro Fusion Framework, the dynamics shaping why West Sweden was finally regarded as a dysfunctional arena for regional action are explained by a shift of attention and action among regional actors in Western Sweden that led to pressure for further institutional adaptation in order to meet the demand of how ‘to get the best out of the EU’. Further, this redefinition of how to handle EU-affairs within the upload-oriented position was accompanied by positive attitudes towards the potential to bypass the state and thereby pursue regional priorities directly in Brussels given the compound nature of the EU. In contrast, those regional actors that are found to be more download-oriented often question the benefits of uploading activities in practice and advocate close relations to the state. A coherent oriented position recognises the importance of activities related to both of the vertical dimensions of Europeanisation.

Extending the Simple Knowledge Organization System for Concept Management in Vocabulary Development Applications

In this article, we describe the development of an exten- sion to the Simple Knowledge Organization System (SKOS) to accommodate the needs of vocabulary devel- opment applications (VDA) managing metadata schemes and requiring close tracking of change to both those schemes and their member concepts. We take a neo- pragmatic epistemic stance in asserting the need for an entity in SKOS modeling to mediate between the abstract concept and the concrete scheme. While the SKOS model sufficiently describes entities for modeling the current state of a scheme in support of indexing and search on the Semantic Web, it lacks the expressive power to serve the needs of VDA needing to maintain scheme historical continuity. We demonstrate prelimi- narily that conceptualizations drawn from empirical work in modeling entities in the bibliographic universe, such as works, texts, and exemplars, can provide the basis for SKOS extension in ways that support more rig- orous demands of capturing concept evolution in VDA.

How did the AD 1755 tsunami impact on sand barriers across the southern coast of Portugal?

Tsunamis are highly energetic events that may destructively impact the coast. Resolving the degree of coastal resilience to tsunamis is extremely difficult and sometimes impossible. In part, our understanding is constrained by the limited number of contemporaneous examples and by the high dynamism of coastal systems. In fact, longterm changes of coastal systems can mask the evidence of past tsunamis, leaving us a short or incomplete sedimentary archive. Here, we present a multidisciplinary approach involving sedimentological, geomorphological and geophysical analyses and numerical modelling of the AD 1755 tsunami flood on a coastal segment located within the southern coast of Portugal. In particular, the work focuses on deciphering the impact of the tsunami waves over a coastal sand barrier enclosing two lowlands largely inundated by the tsunami flood. Erosional features documented by geophysical data were assigned to the AD 1755 eventwith support of sedimentological and age estimation results. Furthermore, these features allowed the calibration of the simulation settings to reconstruct the local conditions and establish the run-up range of the AD 1755 tsunami when it hit this coast (6– 8 m above mean sea level). Our work highlights the usefulness of erosional imprints preserved in the sediment record to interpret the impact of the extreme events on sand barriers
