La complexite des conditions ecologiques de la plaine de l'habra (oranie), l'heterogeneite de la repartition des especes et des communautes halophiles de la zone, reparties suivant un double gradient de xericite et d'humidite le lourd impact de l'action antropique ont conduit a choisir une methode d'etude d'echantillonnage stratifiee de la vegetation. Cette plaine de 50000 ha est consideree comme une zone humide littorale de tres grande importance. Elle presente un interet ecologique remarquable. Elle est cernee par un long complexe dunaire cote mer et par une succession de djebels vers l'interieur. Les eaux de ruissellements d'un vaste bassin versant tendent a s'y accumuler, d'ou la presence ici de zones humides. Ce complexe hebergeait une avifaune aquatique, grace a la presence d'une vegetation specialisee composee essentiellement d'halophytes. L'intervention de l'homme se caracterise par une mise en valeur des terres situees au sud de la plaine et une canalisation du reseau hydrographique. On assiste alors a l'emergence d'un processus de degradation qui pourrait compromettre a jamais le retour de la plaine a ses aspects d'avant la mise en valeur. Cette etude constitue a la fois une synthese des actions de l'homme et une analyse des reactions des facteurs naturels pouvant expliquer la dynamique des complexes de vegetation. Parmi les facteurs contraignants etudies, les caracteristiques pedologiques ont fait l'objet d'analyses approfondies prenant en compte la granulometrie, le calcaire actif, la matiere organique, les cations echangeables, les cations solubles, et les anions, ainsi que les parametres physiques. Une classification des sols a ete proposee rattachant la zone aux solontchaks

In 1991 a private town for Afrikaners was established on the bank of the Orange River, in the semi-desert of South Africa’s Northern Cape Province. As a deliberately Afrikaans, and thus white, community, the town’s aims and existence are controversial, but both its principles and practicalities are not unique. Endeavouring to build an Afrikaner homeland in multiracial South Africa seems incongruous, signalling a retreat from social heterogeneity as a fact of the contemporary world. It raises questions about what people do following a social, political and economic paradigm shift, and about what is occurring within a country with multiple and contradictory accounts of history and a traumatic recent past. It also means resisting the pressure to deal with the past, and therefore the present, in a certain way. Consequently, the frequent question of whether or not the town as an enterprise, or its residents, are racist, reveals instead a complex ordering of society. Life in Orania is filled with ordinary everyday activities of earning a living, raising and educating children, socialising, and practising religion in a town where Christian principles are explicit, each combining elements of intentionality and contingency. Once superficial similarity between residents can be taken for granted, the focus shifts to the differences between them, which rise and fall in importance, highlighting the circumstantial nature of group solidarity. This raises the question of what the differences within the community are, how deeply they reach, and where fundamental commonalities lie that prompt them to choose to build a future together. For the few hundred people involved in the enterprise, Orania is the only way they think they will have a recognisable future: they fear the demise of Afrikaners as an ethnic group through cultural assimilation or dispersal, emigration, and population decline. Their position of victimhood and vulnerability, shaped by the past, shapes their present actions in turn. Afrikaners’ interpretation of themselves as victims is easily supported by the popular historical narrative that Afrikaners have always struggled against outside authorities to be self-determining. This ethnographic study reveals that Orania is a concrete response to the fear that there may not be a place for Afrikaners in South Africa’s future, in the country to which they feel they belong and where their identity is rooted.

I miss the smell of orange blossoms, which used to flood the countryside. But as a city grows, the land surrounding it dies. You cannot roll down your windows anymore and smell the
sweet scent dancing off the buds. You will however find impressive theme parks, factory-style chain stores and restaurants. If you look close enough, you'll also see disgruntled souls of a once naturally spectacular culture of people. Laid back like the sands of Florida's coast. But now there are bills, traffic, and IKEA. This collection of essays is an attempt to escape such an
experience. To explain such an existence, and to explore an eschewal from the inevitable, retail therapy. Xanthomonas axonopodis, often known as citrus cankers, is a bacterial disease affecting most citrus species. Dead tissue forms, then slowly grows, and consumes, then kills the fruits of labor. Grapefruits are the most susceptible to the disease. There was an outbreak from 1910, to 1931. Another from 1986 to 1994, and rumors sprang less than a year later stating the canker was back. To solve most outbreaks, famers and officials just burn the trees to complete, and utter ash. In 2006, the USDA stated eradication of the disease was impossible. If this sounds like cancer, the trust me, you’re not crazy. Florida is known for its beaches, hospitality, and it’s citrus.B.A.

Cette thèse étudie le sémantisme du mot latin oratio, en appliquant les méthodes de l'analyse sémique et en utilisant les catégories de la pragmatique. Nom de la parole dont l'étymologie demeure peu sûre, oratio est d'abord expliqué par orare, qui signifie moins souvent "demander" à l'époque archaïque que "parler de manière argumentée", et qui peut être comparé au grec euchomai, "revendiquer avec éloquence". Ainsi, chez Plaute et Terence, oratio renvoie surtout à l'argumentation ; mais c'est aussi la manière de parler exprimant une disposition, caractérisant un rôle ou une position. Dans La Rhétorique à Hérennius et chez Cicéron, le "discours argumenté", qui correspond à logos, s'élargit à d'autres formes de la persuasion, intégrant les passions et l'action oratoire ; à partir de "manière de parler" se développe, dans la langue de la rhétorique et sous l'influence de lexis, le sens nouveau de "style, forme du discours", avec ses variantes "prose" et "phrase" (unité de style) ; enfin, de logos viennent les acceptions "énoncé" (unité de discours) et "langage", associé à ratio "raison". Par rapport à uerbum et à sermo, oratio définit une parole à la fois orientée vers l'action et inséparable de l'énonciation.

Questa tesi tratta di scambio di dati aperti (open data exchange). In particolare, tratta di intervalli
temporali con annesse informazioni di vario tipo.
Le attività commerciali, come aziende, bar, ristoranti, cinema, teatri, e via dicendo, hanno
bisogno di un modo comune per poter condividere i dati inerenti ai propri orari (timetable). Lo
scopo di questa tesi è quello di mostrare un modello efficiente, compatto e completo per poter
condividere tali informazioni con l'ausilio di formati standard (XML).
Oggi giorno esistono diverse soluzioni atte a far fronte a questa necessità ma si tratta di soluzioni
incomplete e che gestiscono tali informazioni separatamente.
Il problema sorto è quello di avere un'unica struttura che posso unificare informazioni di diverso
carattere con gli orari di un'attività: un cinema ha la necessità di fornire orari di diverse proiezioni
svolte in sale diverse, una tournée dovrà poter specificare le coordinate geografiche del prossimo
evento e così discorrendo.

Au cours du cycle hercynien, l'evolution geodynamique du massif autochtone des traras et celle du massif tello-rifain de madakh peuvent etre respectivement comparees a celles deja proposees dans les boutonnieres hercyniennes de la meseta orientale marocaine et dans les noyaux beticorifo-kabyles. Dans cette hypothese, les segments paleozoiques du maghreb ainsi que ceux de la zone sud-iberique s'inscrivent dans un cadre paleogeographique essentiellement gondwanien, ou le paleozoique de madakh occupe la position d'un maillon intermediaire, a l'articulation entre le troncon autochtone maghrebin et les noyaux hercyniens de mediterranee occidentale precites. Au debut du cycle alpin, pendant le jurassique, la marge continentale oranaise du craton africain est le siege d'une sedimentation de plate-forme essentiellement controlee par l'eustatisme (mise en evidence de sequences de depot), combine a une tectonique en distension. Du tithonique au turonien subsiste, au sud, un domaine pretellien a facies de plate-forme ou se succedent en alternance des depots terrigenes et des depots carbonates. Plus au nord, le domaine tellien oranais evolue en bassin flysch au cours d'une phase en transtension accompagnee par des manifestations volcaniques (d'age postneocomien) et de phenomenes halocinetiques precoces. L'intervalle coniacien-campanien correspond ensuite a une periode tectogene dominee par une transpression generatrice de plis isoclinaux et d'un metamorphisme de faible intensite. Cet episode compressif est suivi par une periode de relachement des contraintes induisant une reprise du diapirisme et des resedimentations (olistostromes maastrichtiens). En conclusion, ce schema evolutif est integre au cadre geodynamique tellien a l'echelle de l'orogene alpin des maghrebides

Projeto de Pós-Graduação/Dissertação apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Ciências FarmacêuticasDurante longos anos, os antagonistas da vitamina K e as heparinas foram os únicos anticoagulantes disponíveis. Apesar de eficazes na prevenção/tratamento das doenças tromboembólicas, apresentam numerosas limitações. No sentido de ultrapassar estas limitações, têm vindo a ser desenvolvidos novos fármacos, que ao contrário dos anteriores atuam num único fator da coagulação específico. Após vários estudos de eficácia e segurança, o dabigatrano etexilato (inibidor direto da trombina), o rivaroxabano e o apixabano (inibidores diretos do fator Xa) foram aprovados para prevenção de acidente vascular cerebral (AVC) e do tromboembolismo venoso em pacientes submetidos a artroplastia eletiva da anca ou joelho, para reduzir o risco de AVC e embolismo sistémico em pacientes com fibrilhação auricular não-valvular e também como tratamento em pacientes com trombembolismo venoso agudo. Estes novos anticoagulantes orais além de serem farmacologicamente previsíveis, não sofrem interações significativas com alimentos, nem com outros fármacos, não necessitam de monitorização laboratorial regular e são de administração oral. Os resultados dos estudos demonstraram que são pelo menos tão eficazes como a varfarina mas mais seguros, uma vez que apresentam um risco de hemorragias major inferior. No entanto, muito ainda está por explorar, sendo necessário prosseguir com as investigações nesta área, conhecendo melhor os efeitos a longo prazo e garantindo uma melhor eficácia e segurança para os pacientes.
For many years, vitamin K antagonists and heparins were the only available anticoagulants. Although effective in the prevention/treatment of thromboembolic diseases, they have numerous limitations. In order to overcome these drawbacks, new drugs that act on a single specific coagulation factor have been developed. After several studies on efficacy and safety, dabigatran etexilate (direct thrombin inhibitor), rivaroxaban and apixaban (factor Xa inhibitors) have been approved for prevention of stroke and venous thromboembolism in patients undergoing elective arthroplasty of hip or knee, to reduce the risk of stroke and systemic embolism in patients with non-valvular atrial fibrillation and in the treatment of patients with acute venous thromboembolism. These new oral anticoagulants are pharmacologically predictable, do not suffer from interaction with other drugs or with food, do not require regular laboratory monitoring and are orally active. The results of the studies showed that are at least as effective as warfarin but safer, since the risk of major bleeding is shorter. However, much remains to be explored, it is necessary to proceed with the investigations in this area, ensuring better efficacy and safety for patients.

Introduction: oral breathing (RO) can influence tongue movements patterns and this can cause persistent alterations in speech, chewing and swallowing throughout life. Studies show that the use of acoustic analysis allows us to infer tongue position during the production of speech. This can be helpful in the processes of diagnosis and speech therapy. Objectives: to present acoustic data of the formant patterns (frequency and intensity of the first three formants F1, F2 and F3, and the bandwidth of the first formant F1) of Brazilian Portuguese (PB) oral vowels as produced by individuals diagnosed with mouth breathing (RO) and individuals presenting no respiratory alterations (RN). Methodology: the corpus consisted of words, inserted in carrier sentences, containing all of the seven oral vowels in stressed position and semi-spontaneous speech. It was recorded by two groups of subjects (RO and RN). These two groups were further divided into two age groups (7-10 years and 10 years and one month to 12 years). Results: statistical differences between RO s and RN s vowel formants (frequency and intensity) have been found. The comparison between the vowel formant structures revealed that the F1 frequencies of the open vowels produced by the RO group were lower than those produced by the RN group, but the F2 frequencies were found to be lower in anterior vowels. These data can be interpreted as related to diminished tongue movement and jaw openness. The comparison among age groups (7 years -10 years and 10 years and 1 month 12 years) within RO and RN groups showed that all formant frequencies (F1, F2 and F3) of the vowels produced by the 7 -10 age group were higher than the older group. This finding can be interpreted as correlated to laryngeal and craniofacial growth. The intensity values of the vowels produced by the RO group were found to be higher than the ones produced by the RN group. This finding can to be correlated with the higher degrees of laryngeal tension (hyperfunction) which characterized RO s voice qualities and characteristics of oral cavity size due to high and narrowed palate area. Conclusion: comparison between the formant structures of the vowels produced by the RO and the RN groups were found to differ in terms of formant frequency (F1, F2 and F3) and intensity (I1, I2 e I3)
Introdução: a ocorrência de respiração oral (RO) interfere negativamente no posicionamento da língua, podendo causar alterações persistentes de fala, mastigação e deglutição por várias etapas da vida. Estudos mostram que o instrumental acústico propicia a condição de inferir o posicionamento do dorso da língua durante a produção de fala, o que poderia auxiliar os processos diagnóstico e terapêutico da RO. Objetivo: apresentar dados acústicos comparativos do padrão de formantes (frequência, intensidade dos três primeiros formantes F1, F2 e F3 e banda do primeiro formante) das vogais orais do português brasileiro (PB) de amostras de fala de indivíduos com diagnóstico de respiração oral (RO), em comparação a indivíduos sem alterações respiratórias (RN). Metodologia: 8 falantes com respiração oral e 8 sem alterações respiratórias com idades entre 07 a 10 anos e 10 anos e 01 mês a 12 anos foram submetidos à sessão de gravação de amostras de fala contendo trechos de fala semi-espontânea e sentenças-veículo com as sete vogais orais do PB inseridas. As gravações foram analisadas por meio do software de livre acesso Praat, para extração de medidas acústicas referentes à freqüência, intensidade e banda de formantes. As medidas acústicas foram submetidas à análise estatística por meio do teste T. Resultados: A caracterização do padrão formântico das vogais orais do grupo RO em relação ao RN revelou diferenças estatísticas em termos dos parâmetros de frequência e intensidade. No caso da frequência, F1 revelou-se rebaixado nas vogais abertas e semi abertas do grupo RO, enquanto F2 revelou-se rebaixado nas vogais anteriores do grupo RO. Tais dados sugerem diminuição da movimentação de língua (no eixo da altura e do deslocamento ântero-posterior) e da abertura da mandíbula. Quando foram comparadas as subfaixas etárias (07 a 10 anos e 10 anos e 01 mês a 12 anos) para cada um dos grupos (RO e RN) detectou-se aumento de todas as freqüências formânticas (F1, F2 e F3) na primeira subfaixa etária, revelando que houve ampliação da extensão total do trato vocal na etapa seguinte, provavelmente pelo processo de crescimento craniofacial e laríngeo. As medidas de intensidades formânticas (I1, I2 e I3) apresentaram-se aumentadas no grupo RO em relação ao RN. Tal achado foi relacionado a efeitos de ajustes de tensão laríngea (hiperfunção) e de modificações na dimensão da cavidade oral consequentes ao quadro de respiração oral, tais como palato duro alto e estreitado. Conclusão: os falantes respiradores orais apresentaram alterações na estrutura formântica das vogais orais do PB, em comparação aos dados de falantes sem alteração da respiração, com destaque para as medidas de freqüência (F1, F2 e F3) e de intensidade (I1, I2 e I3)

This research addressed two important issues concerning conservation of orang-utans in
Indonesia, the prevalence of diseases in orang-utans at reintroduction centres and the
extent of intra-subspecific genetic variation between isolated populations of Bornean
orang-utans. The research was conducted at the Wanariset Orang-utan Reintroduction
Centre in East Kalirnantan fiom 1994 to 1997, during which time extensive field
excursions were made throughout Borneo, and at the Biomedical Primate Research
Centre in the Netherlands in 1998.
Analysis of clinical records fiom 1991 to 1997 showed that during this period 339
orang-utans were admitted to Wanariset, of which 96 (28.3%) died and 108 (31.8%)
were released. Studies were designed to identify and determine the prevalence of
diseases, specifically gastro-intestinal parasites, tuberculosis and certain viral diseases.
Further studies defined the factors associated with mortalities of orang-utans at the
reintroduction centre.
Gastro-intestinal parasites, in particular Strongyloides spp. and Balantidium coli, posed
health problems for rehabilitant orang-utans. Strongyloides spp. and Strongyle sp. eggs
and B. coli were detected in faecal samples from new arrivals, rehabilitant, released and
wild individuals. Trichuris trichura was present in new arrivals, released and rehabilitant
orang-utans, whereas Ascaris sp., and Cyclospora sp. were present only in rehabilitants.
There was a high prevalence of B. coli in new arrivals (41.6%), rehabilitants (100%) and
released individuals (100%) and a low prevalence in wild individuals (12.5%). Faecal egg counts of individuals infected with Strongyloides spp. showed that 47.8% of
rehabilitants and 14.3% of new arrivals had egg counts over 1000 eggs/gm, 81.8% of
released individuals had egg counts less than 500 eggslgm and all wild individuals had egg
counts less than 100 eggs/mg. Strongyloidosis was the primary cause of death (21.9%)
of rehabilitant orang-utans, prior to the incorporation of oral ivermectin into the parasite
control program.
There was a low prevalence of tuberculosis, which was detected in one individual
(0.8%) and suspected to have caused the death of two others (2.1% of deaths).
Diagnosis of tuberculosis in orang-utans was complicated by inaccuracies and
difficulties in interpreting the diagnostic tests commonly used in humans and nonhuman
primates. Further research is required to develop more reliable and accurate tests
for the diagnosis of tuberculosis in orang-utans.
A study of the serological prevalence of a number of viral infections in captive orangutans
showed evidence of exposure to hepatitis B virus (42.6%), hepatitis A virus
(34.9%), herpes simplex viruses (14.7%), simian D-type retroviruses (11.2%) and
human T-lymphotrogic viruses (1.4%). There was no evidence of exposure to simian or
human immunodeficiency viruses.
Molecular studies to determine the origin of the hepatitis B virus, showed the virus was
not of human origin as has been generally assumed, but was an indigenous virus which
also occurred naturally in wild populations. The virus was subsequently named Orangutan
Hepadnavirus.
A molecular study using mitochondrial DNA was undertaken to determine whether
there was significant genetic diversity between six isolated populations of wild orangutans
within Borneo. It was concluded that there are at least four genetically distinct
populations located in East Kalimantan, southwest Kalirnantdcentral Kalirnantan,
northwest KalimantdSarawak, and Sabah.
The findings of this research are discussed in terms of the implications for management
policies for reintroduction centres, as well as for the conservation of wild populations.
They will also be of relevance to zoos and primate centres.

This research addressed two important issues concerning conservation of orang-utans in Indonesia, the prevalence of diseases in orang-utans at reintroduction centres and the extent of intra-subspecific genetic variation between isolated populations of Bornean orang-utans. The research was conducted at the Wanariset Orang-utan Reintroduction Centre in East Kalirnantan fiom 1994 to 1997, during which time extensive field excursions were made throughout Borneo, and at the Biomedical Primate Research Centre in the Netherlands in 1998.
Analysis of clinical records fiom 1991 to 1997 showed that during this period 339 orang-utans were admitted to Wanariset, of which 96 (28.3%) died and 108 (31.8%) were released. Studies were designed to identify and determine the prevalence of diseases, specifically gastro-intestinal parasites, tuberculosis and certain viral diseases. Further studies defined the factors associated with mortalities of orang-utans at the reintroduction centre.
Gastro-intestinal parasites, in particular Strongyloides spp. and Balantidium coli, posed health problems for rehabilitant orang-utans. Strongyloides spp. and Strongyle sp. eggs and B. coli were detected in faecal samples from new arrivals, rehabilitant, released and wild individuals. Trichuris trichura was present in new arrivals, released and rehabilitant orang-utans, whereas Ascaris sp., and Cyclospora sp. were present only in rehabilitants. There was a high prevalence of B. coli in new arrivals (41.6%), rehabilitants (100%) and released individuals (100%) and a low prevalence in wild individuals (12.5%). Faecal egg counts of individuals infected with Strongyloides spp. showed that 47.8% of rehabilitants and 14.3% of new arrivals had egg counts over 1000 eggs/gm, 81.8% of released individuals had egg counts less than 500 eggslgm and all wild individuals had egg counts less than 100 eggs/mg. Strongyloidosis was the primary cause of death (21.9%) of rehabilitant orang-utans, prior to the incorporation of oral ivermectin into the parasite control program.
There was a low prevalence of tuberculosis, which was detected in one individual (0.8%) and suspected to have caused the death of two others (2.1% of deaths). Diagnosis of tuberculosis in orang-utans was complicated by inaccuracies and difficulties in interpreting the diagnostic tests commonly used in humans and nonhuman primates. Further research is required to develop more reliable and accurate tests for the diagnosis of tuberculosis in orang-utans.
A study of the serological prevalence of a number of viral infections in captive orangutans showed evidence of exposure to hepatitis B virus (42.6%), hepatitis A virus (34.9%), herpes simplex viruses (14.7%), simian D-type retroviruses (11.2%) and human T-lymphotrogic viruses (1.4%). There was no evidence of exposure to simian or human immunodeficiency viruses.
Molecular studies to determine the origin of the hepatitis B virus, showed the virus was not of human origin as has been generally assumed, but was an indigenous virus which also occurred naturally in wild populations. The virus was subsequently named Orangutan Hepadnavirus.
A molecular study using mitochondrial DNA was undertaken to determine whether there was significant genetic diversity between six isolated populations of wild orangutans within Borneo. It was concluded that there are at least four genetically distinct populations located in East Kalimantan, southwest Kalirnantdcentral Kalirnantan, northwest KalimantdSarawak, and Sabah.
The findings of this research are discussed in terms of the implications for management policies for reintroduction centres, as well as for the conservation of wild populations. They will also be of relevance to zoos and primate centres.

Selective Laser Sintering (SLS) or Laser Sintering (LS) allows functional parts to be produced in a wide range of powdered materials using a dedicated machine, and is thus gaining popularity within the field of rapid prototyping. Two current manufacturers of LS equipment and materials are EOS GmbH and 3D Systems. The PA2200 semi-crystalline polyamide powder studied here was developed by EOS and was processed using the 3D Systems Sinterstation 2500 HiQ LS machine. One of the advantages of employing LS is that the loose powder of the building chamber can be recycled. However, the properties of some recycled powders such as polyamide 12 (PA 12) deteriorate by comparison to those of fresh powder. Fabricating parts using only new powder, although providing the best quality, is considerably more expensive than using recycled powder. On the other hand, using recycled powder creates the problem of the coarse, rough, and uneven surface texture. This thesis examines LS fabricated parts which are affected by the "orange peel" phenomenon due to the usage of recycled PA 12 powder. This problem must be addressed before the technology can be widely accepted. This thesis presents the problematic areas and proposes solutions to manage and utilise the recycled powder. Further, the thesis discusses experimental work on the deterioration or ageing of PA 12 powder properties in the LS process, the microstructure of "orange peel" texture and the improvement of part surface finish to avoid the "orange peel" problem.

Foi projetado e construído um espectrômetro Mini-Orange (MO) para eléctrons, utilizando imãs planos permanentes e um detector de barreira de superfície. Foram determinadas as funções de transmissão de diferentes configurações do sistema, para energias entre 200-1100 keV. Foi desenvolvido um modelo matemático do sistema, a partir de solução analítica para o campo de um imã plano e da integração numérica da equação de movimento dos eléctrons no campo de MO. As funções de transmissão assim obtidas foram comparadas aos resultados experimentais e mostraram um bom acordo para energias baixas e intermediárias.A Mini-Orange spectrometer for electrons was designed and built, using plane permanent magnets and a surface barrier detector. Transmission functions were obtained for various system configurations and for energies between 200-1100 keV. A mathematical model of the system was developed, using the analytical solution for the field of a plane magnet and the numerical integration of the equation of motion of the electrons in the MO magnetic field. The calculated transmission functions were compared to the experimental data, showing a good agreement for low and intermediate energies.

Research has shown that the oral health of Māori is far worse than non-Māori across all age groups. The objective of this research study was to assess the dental wellbeing of 5-year olds with a specific focus on Māori children currently residing in the Hamilton City region. In addition, this research focused on the impact that social, economic, cultural and environmental factors have on oral health. A total of 32 participants were invited to take part in this research: 15 5-year-old children from three selected schools, 15 (of the children's) caregivers and 2 dental therapists who work in the Hamilton City region. The findings indicated that overall Māori children and children of lower socio-economic status had a much higher prevalence of dental caries (tooth decay) than non-Māori children and children of higher socio-economic status. A number of contributing factors were shown to be responsible for this disparity including the cultural inappropriateness of oral health services and resources, affordability, role-modelling, parental awareness and education, and the transient nature of families. It was found that no one strategy or intervention will achieve dramatic improvements in Māori oral health as a concerted effort is required by Local and Central Government, the Health Sector and Māori communities.

Unpasteurized (condition A) and pasteurized (condition B) orange juice samples were stored frozen for eight months. In addition, pasteurized samples were also aseptically packaged and stored at +1°C in polyethylene bags (condition C). Nine quality parameters were monitored during the eight months of storage: sedimentation of the pulp, cloud measurement, aroma volatiles, ascorbic acid concentration, viscosity, density, colour, sugar content (sucrose, glucose and fructose), organic acids (malic and citric), in addition to sensory analysis. The optimum storage condition for freshly processed orange juice was the unpasteurized frozen storage method (condition A). The juice retained most of its chemical and physical properties and was rated by a sensory panel to have the highest sensory score.

High pressure (HP) processing has been emerging rapidly as a novel technique for non-thermal preservation of foods. Application of HP processing for shelf life extension of orange juice was the principal objective of the current research. To accomplish this objective, and to establish a scientific basis for HP processing of orange juice, a systemic approach was used which included the evaluation of: (a) HP inactivation kinetics of pectin methyl esterase (PME, the key enzyme in orange juice implicated with respect to quality changes), (b) destruction of spoilage microorganisms and changes in product quality, (c) HP process verification and finally, (d) storage studies on HP treated orange juice.In preliminary studies, the effect of HP treatment on indigenous microorganisms, texture and color of selected fresh fruits and vegetables were evaluated. Results showed that HP had a significant effect on the destruction of microorganisms. Product texture and color were mildly affected, often resembling the appearance of mildly heat-treated products.
Pressure induced inactivation kinetics of pectin methyl esterase (PME) was investigated at pH 3.7 and 3.2 in freshly squeezed single strength (12.6°Brix) and concentrated (10--40° Brix) orange juice. Results showed a biphasic nature of pressure induced inactivation of PME in both juices. The first phase consisted of rapid change in inactivation of enzyme, designated as instantaneous pressure kill (IPK), due to pulse pressurization, followed by gradual inactivation of enzyme, characterized by a first order rate of inactivation during pressure hold-time.
Combination treatment involving pressure cycle, pressure level and pressure hold-time was then evaluated for inactivation of PME using a response surface methodology. Overall, pressure pulse had a lower effect on inactivation of PME compared to other factors.
Pressure destruction kinetics of Leuconostoc mesenteroides and Saccharomyces cerevisiae the spoilage organisms in orange juice, were then investigated. Pressure destruction kinetics followed the same dual effect behavior, as observed with PME inactivation. IPK effect increased with pressure cycles and was more pronounced with S. cerevisiae that Leu. mesenteroides.
Storage studies of HP treated single strength and concentrated orange juice were conducted at selected temperatures (4, 10 and 20°C). Results showed that treated juice was microbiologically stable from a few days to several weeks depending on type of juice, storage temperature and processing conditions. (Abstract shortened by UMI.)

Groundwater in portions of Orange County exhibits a characteristic color attributed to the presence of naturally occurring organic matter. Dissolved organic carbon, largely in the form of humic and fulvic acids, is found at concentrations ranging from 0.3 mg/L to 14.4 mg/L. Organic rich strata is believed to be the source of dissolved organic carbon (DOC). Removal of DOC from groundwater is necessary to reduce water color and trihalomethane formation potential (THMFP). Organic carbon characteristics such as average apparent molecular weight and carboxylic acidity appear to effect groundwater treatability and THMFP. Increased organic carbon removal efficiency was realized with decreasing carboxylic acidity and lower apparent molecular weight organic carbon appears to contribute a greater amount of THMFP per milligram groundwater DOC. Alum coagulation was consistently more successful in removing DOC from solution while ozone oxidation achieved the greatest reduction in sample reactivity.

Previous issue date: 2010O presente trabalho consiste na avaliação dos critérios e procedimentos analíticos adotados no estudo da faiança, uma categoria de material arqueológico freqüente e normalmente abundante nos sítios arqueológicos coloniais brasileiros, principalmente no Nordeste do Brasil. A escolha do tema se deve fundamentalmente à relação entre sua potencialidade enquanto documento material e o acesso objetivo às informações nele contidas. A subjetividade do processo analítico, no entanto, no que se refere à faiança, não permitiu, até o momento, um confiável acesso a esta documentação. Ao converter a faiança em documento legível, no entanto, o arqueólogo poderá recuperar informações importantes referentes ao conhecimento e domínio técnico de seus produtores, necessidades, relações comerciais e sociais de época, e perfil de seus consumidores. Vale salientar, no entanto, que apenas a faiança não será suficiente para explicar todas estas relações, mas poderá fornecer preciosas contribuições. Entretanto, a análise desta categoria de material não tem, até o momento, permitido uma leitura segura desta documentação, uma vez que não se dispõe de critérios analíticos adequados. A abordagem da faiança se baseia, normalmente, em critérios artísticos e não científicos. Conseqüentemente, a necessidade de avaliação e identificação de atributos objetivos que possam ser utilizados no processo de leitura desta categoria de documento é inquestionável. A faiança encontrada em escavações arqueológicas realizadas no Forte Orange, localizado na Ilha de Itamaracá-PE, nos anos de 2002 e 2003 constitui o objeto de estudo deste trabalho. Sua representatividade qualitativa e quantitativa transformou-a em excelente amostra para o estudo

D'après les sources littéraires, la région rhodanienne a été occupée, a la veille de la conquête romaine, par des peuples celtes et ligures, allobroges, Salyens, Volsques et Cavares. Toutefois on connait mal leur localisation, les limites de leurs territoires, leur statut juridique et celui de leurs cités. Dans cette étude nous nous appuierons essentiellement sur Strabon et Pline. Malgré leur relative imprécision, ces deux sources restent des documents indispensables pour connaitre la situation politique et administrative de la région vers la fin du IIe et le début du Ier siècle av. J-c. Quant à l'histoire agraire de la région que couvre la scamnatio, désignée comme réseau D d'Orange, elle a connu un bouleversement considérable, les données cadastrales que nous possédons grâce à l'épigraphie, à la carte topographique actuelle et à la photographie aérienne, témoignent de l'existence de plusieurs réseaux sur le sol de cette région de Provence. Ces données posent un problème délicat du point de vue historique qui a poussé les archéologues aussi bien que les historiens à aborder certaines questions qui s'imposent, d'une part l'identification, la localisation et la morphologie de chacun de ces réseaux, d'autre part la superposition et la juxtaposition, ainsi les limites et les frontières de chacun d'eux. La découverte récente d'un quatrième réseau dans cette région permet de répondre à plusieurs questions posées par les spécialistes de l'archéologie du paysage. Mais cela pose en préalable des problèmes de date et de morphologie qui constituent le deuxième axe de cette étude qui touche à d'autres problèmes concernant l'extension géographique et les limites historiques du réseau D.
