The Scots in Ireland: culture, colonialism and memory, 1315-1826

This thesis examines three key moments in the intersecting histories of Scotland, Ireland and England, and their impact on literature. Chapter one Robert Bruce and the Last King of Ireland: Writing the Irish Invasion, 1315- 1826‘, is split into two parts. Part one, Barbour‘s (other) Bruce‘ focuses on John Barbour‘s The Bruce (1375) and its depiction of the Bruce‘s Irish campaign (1315-1318). It first examines the invasion material from the perspective of the existing Irish and Scottish relationship and their opposition to English authority. It highlights possible political and ideological motivations behind Barbour‘s negative portrait of Edward Bruce - whom Barbour presents as the catalyst for the invasion and the source of its carnage and ultimate failure - and his partisan comparison between Edward and his brother Robert I. It also probes the socio-polticial and ideological background to the Bruce and its depiction of the Irish campaign, in addition to Edward and Robert. It peers behind some of the Bruce‘s most lauded themes such as chivalry, heroism, loyalty, and patriotism, and exposes its militaristic feudal ideology, its propaganda rich rhetoric, and its illusions of freedom‘. Part one concludes with an examination of two of the Irish section‘s most marginalised figures, the Irish and a laundry woman. Part two, Cultural Memories of the Bruce Invasion of Ireland, 1375-1826‘, examines the cultural memory of the Bruce invasion in three literary works from the Medieval, Early Modern and Romantic periods. The first, and by far the most significant memorialisation of the invasion is Barbour‘s Bruce, which is positioned for the first time within the tradition of ars memoriae (art of memory) and present-day cultural memory theories. The Bruce is evaluated as a site of memory and Barbour‘s methods are compared with Icelandic literature of the same period. The recall of the invasion in late sixteenth century Anglo-Irish literature is then considered, specifically Edmund Spenser‘s A View of the State of Ireland, which is viewed in the context of contemporary Ulster politics. The final text to be considered is William Hamilton Drummond‘s Bruce’s Invasion of Ireland (1826). It is argued that Drummond‘s poem offers an alternative Irish version of the invasion; a counter-memory that responds to nineteenth-century British politics, in addition to the controversy surrounding the publication of the Ossian fragments. Chapter two, The Scots in Ulster: Policies, Proposals and Projects, 1551-1575‘, examines the struggle between Irish and Scottish Gaels and the English for dominance in north Ulster, and its impact on England‘s wider colonial ideology, strategy, literature and life writing. Part one entitled Noisy neighbours, 1551-1567‘ covers the deputyships of Sir James Croft, Sir Thomas Radcliffe, and Sir Henry Sidney, and examines English colonial writing during a crucial period when the Scots provoked an increase in militarisation in the region. Part two Devices, Advices, and Descriptions, 1567-1575‘, deals with the relationship between the Scots and Turlough O‘Neill, the influence of the 5th Earl of Argyll, and the rise of Sorley Boy MacDonnell. It proposes that a renewed Gaelic alliance hindered England‘s conquest of Ireland and generated numerous plantation proposals and projects for Ulster. Many of which exhibit a blurring‘ between the documentary and the literary; while all attest to the considerable impact of the Gaelic Scots in both motivating and frustrating various projects for that province, the most prominent of which were undertaken by Sir Thomas Smith in 1571 and Walter Devereux, 1st Earl of Essex in 1573.

Obtenção e caracterização de queratinase de bacillus sp. P45 a partir de coprodutos e aplicação na produção de queijos cremosos enriquecidos com chia e quinoa

As proteases constituem 60-65% do mercado global das enzimas industriais e são utilizadas na indústria de alimentos no processo de amaciamento de carne, na síntese de peptídeos, preparo de fórmulas infantis, panificação, cervejarias, produtos farmacêuticos, diagnósticos médicos, como aditivos na indústria de detergentes e na indústria têxtil no processo de depilação e transformação do couro. Proteases específicas produzidas por micro-organismos queratinolíticos são chamadas de queratinases e distinguem-se de outras proteases pela maior capacidade de degradação de substratos compactos e insolúveis como a queratina. Atualmente, processos que apontem o uso total das matérias-primas e que não resultem em impactos negativos ao meio ambiente tem ganhado destaque. Dentro desta temática, destacam-se a reutilização da farinha de penas residual durante o cultivo do Bacillus sp. P45 para produção de proteases e a biomassa residual de levedura, ambas com elevados teores de proteínas, podendo ser utilizadas no cultivo do Bacillus sp. P45 para obtenção de proteases. O objetivo deste trabalho foi obter a enzima queratinase purificada em grandes quantidades, sua caracterização, bem como a sua aplicação em processos de coagulação enzimática do leite para o desenvolvimento de um queijo cremoso enriquecido com farinha de chia e quinoa. Além disso, aplicar diferentes coprodutos para produção de enzimas proteolíticas e queratinolíticas. A presente tese foi dividida em quatro artigos: no primeiro foi realizado a obtenção da queratinase purificada em maiores quantidades e a determinação dos parâmetros de estabilidade térmica e a influência de componentes químicos na atividade enzimática. A obtenção da enzima em maiores quantidades alcançou fatores de purificação de 2,6, 6,7 e 4,0 vezes, paras 1º SAB, 2º SAB e diafiltração, respectivamente. A recuperação enzimática alcançou valores de 75,3% para o 1º SAB, 75,1% no 2º sistema e 84,3% na diafiltração. A temperatura de 55ºC e o pH 7,5 foram determinados como ótimos para atividade da enzima queratinase. O valor da energia de desativação (Ed) médio foi de 118,0 kJ/mol e os valores de z e D variaram de 13,6 a 18,8ºC, e 6,9 a 237,3 min, respectivamente. Além disso a adição de sais (CaCl2, CaO, C8H5KO4 e MgSO4) elevou a atividade da enzima na presença destes compostos. O segundo artigo apresenta a aplicação da queratinase como coagulante de leite bovino e sua aplicação na obtenção de queijo cremoso enriquecido com chia e quinoa. A enzima mostrou atividade de coagulação semelhante ao coagulante comercial, na concentração de 30mg/mL. A enzima purificada foi empregada de forma eficiente na fabricação do queijo cremoso, que apresentou valores de pH de 5,3 e acidez de 0,06 a 0,1 mol/L, com elevação durante os 25 dias de armazenamento. O terceiro artigo apresenta o perfil do queijo cremoso enriquecido com farinha de chia e quinoa, o qual apresentou alto índice de retenção de água (>99,0%) e baixos valores de sinérese (<0,72%). Elevados teores de fibras foi verificado (3,0 a 5,0%), sugerindo seu consumo como fonte de fibras. As análises microbiológicas foram de acordo com a legislação vigente. Na análise sensorial foi verificado altos valores de suavidade ao paladar e verificado maiores valores de consistência e untabilidade nas amostras com maiores concentrações de nata e quinoa. O quarto artigo traz a extração de β-galactosidase por ultrassom e o uso da biomassa residual da levedura, bem como o uso de farinha de penas residuais como substrato para obtenção de proteases. O ultrassom foi eficiente para ruptura celular e extração de β-galactosidase, apresentando alta atividade (35,0 U/mL) e rendimento (876,0 U/g de biomassa). A maior atividade proteolítica (1300 U/mL em 32 h) e queratinolítica (89,2 U/mL) verificadas ocorreram utilizando-se a biomassa e a farinha de penas residuais, respectivamente. Maior produtividade proteolítica (40,8 U/mL/h) foi verificado no meio utilizando biomassa residual como substrato. Já a maior produtividade queratinolítica (2,8 U/mL/h) foi alcançada utilizando farinha de penas reutilizada.

Studying and measuring the amount of detergents in sea-water samples in order to eliminate with adsorbents and inorganic nano-adsorbents for the sake of securing the water for marine nourishment pools

Increasing the amount of detergent industries in world in spite of having abundant benefits; entering a new kind of contamination into environment and attract the attention of environment liable of different countries to itself. Entering detergents into an aqueous solution cause pollution of water sources and environment in respect of appearing e problem and charges like: nutritive phenomenon, decomposition of hard group of detergent and producing foam. After using Detergents, they were poured into rivers, seas and lakes and have destructive effect on environment. A lot of hygiene problems were attributed to the water having detergents more than allowed value. So, it is specified the importance of eliminating detergents from contaminated water and it is application for secondary use. In order to attain to this aim, we can use inorganic nano and micro-caolin. In this study the adsorptive properties of detergent on the micro and nano caolin adsorbents were studied and the effect of various parameters like the amount of adsorptive materials, initial concentration of detergent, speed of stirring, electrolyte, temperature, time and pH were determined. The surface area of micro- and nano-caoline was reported 11.867 and 49.1438 m2 g-1, respectively. That increasing in nano-caoline surface area confirms increasing in capacity and more rate of adsorption. The results gained by this research recommend using micro- and nano-caolin as a plentiful, available and effective adsorbents. Also in comparison, using nano-caoline was recommended in order to have more effectiveness.

Avaliação do potencial de formigas (Hymenoptera: formicidae) como vetores mecânicos de bactérias do gêneroSstaphylococcus no ambiente hospitalar.

In a hospital environment, these bacteria can be spread by insects such as ants, which are characterized by high adaptability to the urban environment. Staphylococcus is a leading cause of hospital infection. In Europe, Latin America, USA and Canada, the group of coagulase negative staphylococci (CoNS) is the second leading cause of these infections, according to SENTRY (antimicrobial surveillance program- EUA). In this study, we investigated the potential of ants (Hymenoptera: Formicidae) as vehicle mechanics of Staphylococcus bacteria in a public hospital, in Natal-RN. The ants were collected, day and night, from June 2007 to may 2008, in the following sectors: hospitals, laundry, kitchen, blood bank. The ants were identified according to the identification key of Bolton, 1997. For the analysis of staphylococci, the ants were incubated in broth Tryptic Soy Broth (TSB) for 24 hours at 35 º C and then incubated on Mannitol Salt Agar. The typical colonies of staphylococci incubated for 24 hours at 35 ° C in Tryptic Soy Agar for the characterization tests (Gram stain, catalase, susceptibility to bacitracin and free coagulase). The identification of CoNS was performed through biochemical tests: susceptibility to novobiocin, growth under anaerobic conditions, presence of urease, the ornithine decarboxylation and acid production from the sugars mannose, maltose, trehalose, mannitol and xylose. The antimicrobial susceptibility examined by disk-diffusion technique. The technique of Polymerase Chain Reaction was used to confirm the presence of mecA gene and the ability to produce biofilm was verified by testing in vitro using polystyrene inert surface, in samples of resistant staphylococci. Among 440 ants, 85 (19.1%) were carrying coagulase-negative staphylococci (CoNS) of the species Staphylococcus saprophyticus (17), Staphylococcus epidermidis (15), Staphylococcus xylosus (13), Staphylococcus hominis hominis (10), Staphylococcus lugdunensis (10), Staphylococcus warneri (6), Staphylococcus cohnii urealyticum (5), Staphylococcus haemolyticus (3), Staphylococcus simulans (3), Staphylococcus cohnii cohnii (2), and Staphylococcus capitis (1). No Staphylococcus aureus was found. Among the isolates, 30.58% showed resistance to erythromycin. Two samples of CoNS (2.35%), obtained from the ant Tapinoma melanocephalum collected in the post-surgical female ward, S. Hominis hominis and S. lugdunensis harbored the mecA gene and were resistant to multiple antibiotics, and the specie S. hominis hominis even showed to be a biofilm producer. This study proves that ants act as carriers of multidrug-resistant coagulase-negative Staphylococci and biofilm producers and points to the risk of the spreading of pathogenic microorganisms by this insect in the hospital environment

Increasing the value of household appliances by adding a heat pump system

Historically, domestic tasks such as preparing food and washing and drying clothes and dishes were done by hand. In a modern home many of these chores are taken care of by machines such as washing machines, dishwashers and tumble dryers. When the first such machines came on the market customers were happy that they worked at all! Today, the costs of electricity and customers’ environmental awareness are high, so features such as low electricity, water and detergent use strongly influence which household machine the customer will buy. One way to achieve lower electricity usage for the tumble dryer and the dishwasher is to add a heat pump system. The function of a heat pump system is to extract heat from a lower temperature source (heat source) and reject it to a higher temperature sink (heat sink) at a higher temperature level. Heat pump systems have been used for a long time in refrigerators and freezers, and that industry has driven the development of small, high quality, low price heat pump components. The low price of good quality heat pump components, along with an increased willingness to pay extra for lower electricity usage and environmental impact, make it possible to introduce heat pump systems in other household products. However, there is a high risk of failure with new features. A number of household manufacturers no longer exist because they introduced poorly implemented new features, which resulted in low quality and product performance. A manufacturer must predict whether the future value of a feature is high enough for the customer chain to pay for it. The challenge for the manufacturer is to develop and produce a high-performance heat pump feature in a household product with high quality, predict future willingness to pay for it, and launch it at the right moment in order to succeed. Tumble dryers with heat pump systems have been on the market since 2000. Paper I reports on the development of a transient simulation model of a commercial heat pump tumble dryer. The measured and simulated results were compared with good similarity. The influence of the size of the compressor and the condenser was investigated using the validated simulation model. The results from the simulation model show that increasing the cylinder volume of the compressor by 50% decreases the drying time by 14% without using more electricity.  Paper II is a concept study of adding a heat pump system to a dishwasher in order to decrease the total electricity usage. The dishwasher, dishware and water are heated by the condenser, and the evaporator absorbs the heat from a water tank. The majority of the heat transfer to the evaporator occurs when ice is generated in the water tank. An experimental setup and a transient simulation model of a heat pump dishwasher were developed. The simulation results show a 24% reduction in electricity use compared to a conventional dishwasher heated with an electric element. The simulation model was based on an experimental setup that was not optimised. During the study it became apparent that it is possible to decrease electricity usage even more with the next experimental setup.

Composição botânica e qualidade do pasto selecionado por ovelhas em caatinga raleada e enriquecida.

Resumo: O presente estudo foi conduzido com o objetivo de determinar a composição botânica e a qualidade da dieta selecionada por ovelhas, através da técnica de micro-histologia fecal, em caatinga raleada e enriquecida com capim massai (Panicum maximum cv. Massai), recebendo diferentes quantidades de concentrado (0; 200; 350 e 500 g de concentrado por dia), e em diferentes períodos do ano (águas, transição água-seca e seca). Foram estimados também o consumo e digestibilidade dos nutrientes, bem como a degradabilidade de espécies forrageiras ingeridas pelas ovelhas. Os experimentos foram realizados na Fazenda Crioula do Meio, pertencente a Embrapa Caprinos e Ovinos em Sobral, CE no período de março a novembro de 2013. No Experimento 1, para a determinação da composição botânica e qualidade da dieta selecionada, foram utilizadas dezesseis ovelhas Somalis brasileira, gestantes, multíparas e peso médio de 30,58+2,48 kg. O acompanhamento da ingestão do pasto pelas ovelhas foi feito em três períodos (águas, transição água-seca e seca), referentes aos meses de abril, junho e agosto de 2013, respectivamente. Amostras das plantas foram coletadas para o preparo das lâminas de referência, e posterior identificação e caracterização dos descritores epidérmicos. O mesmo foi feito para as fezes coletadas nas ovelhas. Com base na proporção de cada espécie identificada nas lâminas fecais que compuseram a dieta, e na composição química das forrageiras identificadas, foi possível determinar a qualidade da dieta ingerida. De 76 espécies observadas no pasto, 33 foram identificadas na dieta das ovelhas, destacando as espécies sabiá (Mimosa caesalpiniaefolia), centrosema (Centrosema sp.), ervanço (Alternanthera brasiliana), massai (Panicum maximum cv Massai) e paco-paco (Wissadula rostrata) como as mais selecionadas pelos animais ao longo dos períodos, chegando a compor mais de 50% da dieta selecionada. Com a chegada do período seco, espécies indesejáveis como o marmeleiro (Croton sonderianus) e o mofumbo (Combretum lepreosum), também fizeram parte das plantas selecionadas. Quanto ao valor nutritivo da dieta selecionada, os animais selecionaram uma dieta com valor nutritivo superior ao amostrado no pasto. No Experimento 2, na mesma condição do experimento anterior, trinta e duas ovelhas Somalis brasileira foram utilizadas para determinação do consumo e digestibilidade dos nutrientes, realizado em três ensaios (abril - terço final de gestação; junho - lactação e agosto - desmame). Para predição do consumo, o indicador LIPE® foi utilizado. Pesagens quinzenais foram realizadas para avaliação do desempenho das ovelhas e dos cordeiros nascidos. O concentrado oferecido favoreceu a maior ingestão e digestibilidade da MS e PB, com efeito substitutivo em relação ao consumo de pasto (P<0,05). Para o período seco, menores consumos foram observados em relação aos períodos das águas e de transição água-seca (P<0,05). Maiores consumos e digestibilidades dos constituintes fibrosos foram observados para as ovelhas não suplementados (P<0,05). Na avaliação do desempenho, a suplementação oferecida determinou os maiores pesos verificados durante a lactação, ao desmame e para os pesos ao nascer e ao desmame dos cordeiros (P<0,05). No Experimento 3, dois ovinos Morada Nova foram utilizados para determinação da degradabilidade da matéria seca (MS), proteína bruta (PB) e fibra em detergente neutro (FDN) de cinco das forrageiras selecionadas pelas ovelhas no Experimento 1: M. caesalpiniaefolia, A. brasiliana, P. maximum cv. Massai, jurema-preta (Mimosa tenuiflora), C. leprosum, nos tempos 0, 6, 24, 48, 72 e 96 horas de incubação. Para cada forrageira, foram determinadas equações para o desaparecimento da MS, PB e FDN. Também foi feito o fracionamento da proteína em suas porções degradáveis e não degradáveis no rúmen. Foi observado maior desaparecimento da MS, PB e FDN, além dos melhores níveis de proteína efetivamente degradada no rúmen para A. brasiliana, seguido pelo P. maximum cv. Massai e M. caesalpiniaefolia. Com as informações obtidas, conclui-se que a micro-histologia fecal apresenta-se como uma técnica viável para avaliações da composição botânica da dieta selecionada por ovinos na caatinga. Ovelhas na caatinga possuem uma grande habilidade de selecionar a dieta, modificando-a ao longo das fases fenológicas, sempre na tentativa de estabelecer uma dieta com melhor valor nutritivo. Forrageiras como A. brasiliana, M. caesalpiniaefolia e o P. maximum cv. Massai, podem ser consideradas um interessante recurso alimentar, em virtude de seu valor nutricional e aproveitamento por ovelhas criadas na caatinga. Abstract: This study was conducted in order to determine the botanical composition and diet quality selected by sheep through fecal micro-histological technique, in thinned and enriched caatinga with Massai grass (Panicum maximum cv Massai.), receiving different amounts of concentrate (0; 200; 350 and 500 g of concentrate per day) at different periods (wet, transition wet-dry and dry). Were also estimated the intake, digestibility, as well as the degradability of forage species eaten by sheep. The experiments were performed in the "Fazenda Crioula do Meio", owned by Embrapa Goats and Sheep, in Sobral, Ceará State, Brazil, from march to november 2013. In Trial 1, sixteen female, pregnant, multiparous, with average body weight of 30,58+2,48 kg Somalis brasileira breed sheep were used to determine the botanical composition and the quality of the selected diet. The monitoring of pasture intake of sheep were conducted in three phenological periods of the caatinga's pasture (wet season, transition wet-dry and dry season). Plant samples were collected for the preparation of the reference slides, with subsequent identification and characterization of epidermal descriptors. The same was done for the feces collected in sheep. Considering the proportion of each species identified in fecal slides which composed the diet, and the chemical composition of forage identified, it was possible to determine the quality of the selected diet. From 76 species observed in the pasture, 33 species was identified in the sheep selected diet, emphasizing the Sabiá (Mimosa caesalpiniaefolia), centrosema (Centrosema sp.), ervanço (Alternanthera brasiliana), massai (Panicum maximum cv Massai) e paco-paco (Wissadula rostrata) as the most selected species by sheep during the study, composing more than 50% of the selected diet. In the Dry Season, undesirable species like marmeleiro (Croton sonderianus) and mofumbo (Combretum leprosum), were also constituent of the diet. Regarding to the nutritional value of selected diet, the sheep selected a diet with more protein than the sampled in the pasture. In the final late gestation, the sheep without supplementation ate a diet above 16% of CP, higher than the selected diet by treatments 350 and 500 g of concentrate per day (P<0.05). Were also observed to the non supplemented sheep, less fiber content intake (P<0.05). In the Trial 2, in the same condition of the first Trial, thirty two Somalis brasileira female sheep were used to determine the intake and digestibility, conducted in three assays (April - third late pregnancy; June - lactation and August - weaning). To predict the intake, the marker LIPE was used. Sheep and lambs were weighted every two weeks to performance evaluation. The concentrate offered to sheep favored to higher intake and digestibility of DM and CP than non supplemented sheep, with inverse relationship to the pasture intake (P<0.05). For the Dry Season, lower intake were observed than for Wet Season and Transition Wet-Dry (P<0.05). Higher intakes and digestibility of the fiber constituents were verified to non supplemented sheep (P<0.05). To performance evaluation, the offered supplementation determined the higher weights observed during lactation and weaning of sheep, and to birth and weaning weights of lambs (P<0.05). In Trial 3, two male sheep were used to determine the degradability of dry matter (DM), crude protein (CP) and neutral detergent fiber (NDF) of five forages selected by sheep in Trial 1: M. caesalpiniaefolia, A. brasiliana, P. maximum cv. Massai, jurema-preta (Mimosa tenuiflora) and C. lepreosum, at zero, 6, 24, 48, 72 and 96 hours of incubation. For each forage, were determined equations for the disappearance of DM, CP and NDF. It was also realized the protein fractions in their degradable and non-degradable in the rumen parts. Was detected a higher disappearance of DM, CP and NDF, as also better proportion of the rumen degradable protein to A. brasiliana, followed by P. maximum cv. Massai and M. caesalpiniaefolia. With the information obtained, it is concluded that the fecal micro histological technique presents as a viable technique to evaluate the selected diet by sheep in caatinga's pasture. On this pasture, the sheep are skilled to select the diet, changing during the phenological phases, trying to form a diet of better nutritive value. Forages as A. brasiliana, P. maximum cv. Massai and M. caesalpiniaefolia, can be considered an interesting food source to ewes kept in the caatinga.

Uso da espectroscopia de reflectância do infravermelho próximo (NIRS) para previsão da composição bromatológica de vagens de algaroba e palma forrageira.

Espécies forrageiras adaptadas às condições semiáridas são uma alternativa para reduzir os impactos negativos na cadeia produtiva de ruminantes da região Nordeste brasileira devido à sazonalidade na oferta de forragem, além de reduzir custo com o fornecimento de alimentos concentrados. Dentre as espécies, a vagem de algaroba (Prosopis juliflora SW D.C.) e palma forrageira (Opuntia e Nopalea) ganham destaque por tolerarem o déficit hídrico e produzirem em períodos onde a oferta de forragem está reduzida, além de apresentam bom valor nutricional e serem bem aceitas pelos animais. Porém, devido à variação na sua composição, seu uso na alimentação animal exige o conhecimento profundo da sua composição para a elaboração de dietas balanceadas. No entanto, devido ao custo e tempo para análise, os produtores não fazem uso da prática de análise da composição químico-bromatológica dos alimentos. Por isto, a espectroscopia de reflectância no infravermelho próximo (NIRS) representa uma importante alternativa aos métodos tradicionais. Objetivou-se com este estudo desenvolver e validar modelos de predição da composição bromatológica de vagem de algaroba e palma forrageira baseados em espectroscopia NIRS, escaneadas em dois modelos de equipamentos e com diferentes processamentos da amostra. Foram coletadas amostras de vagem de algaroba nos estados do Ceará, Bahia, Paraíba e Pernambuco, e amostras de palma forrageira nos estados do Ceará, Paraíba e Pernambuco, frescas (in natura) ou pré-secas e moídas. Para obtenção dos espectros utilizaram-se dois equipamentos NIR, Perten DA 7250 e FOSS 5000. Inicialmente os alimentos foram escaneados in natura em aparelho do modelo Perten, e, com o auxílio do software The Unscrambler 10.2 foi selecionado um grupo de amostras para o banco de calibração. As amostras selecionadas foram secas e moídas, e escaneadas novamente em equipamentos Perten e FOSS. Os valores dos parâmetros de referência foram obtidos por meio de metodologias tradicionalmente aplicadas em laboratório de nutrição animal para matéria seca (MS), matéria mineral (MM), matéria orgânica (MO), proteína bruta (PB), estrato etéreo (EE), fibra solúvel em detergente neutro (FDN), fibra solúvel em detergente ácido (FDA), hemicelulose (HEM) e digestibilidade in vitro da matéria seca (DIVMS). O desempenho dos modelos foi avaliado de acordo com os erros médios de calibração (RMSEC) e validação (RMSECV), coeficiente de determinação (R2 ) e da relação de desempenho de desvio dos modelos (RPD). A análise exploratória dos dados, por meio de tratamentos espectrais e análise de componentes principais (PCA), demonstraram que os bancos de dados eram similares entre si, dando segurança de desenvolver os modelos com todas as amostras selecionadas em um único modelo para cada alimento, algaroba e palma. Na avaliação dos resultados de referência, observou-se que a variação dos resultados para cada parâmetro corroboraram com os descritos na literatura. No desempenho dos modelos, aqueles desenvolvidos com pré-processamento da amostra (pré-secagem e moagem) se mostraram mais robustos do que aqueles construídos com amostras in natura. O aparelho NIRS Perten apresentou desempenho semelhante ao equipamento FOSS, apesar desse último cobrir uma faixa espectral maior e com intervalos de leituras menores. A técnica NIR, associada ao método de calibração multivariada de regressão por meio de quadrados mínimos (PLS), mostrou-se confiável para prever a composição químico-bromatológica de vagem de algaroba e da palma forrageira. Abstract: Forage species adapted to semi-arid conditions are an alternative to reduce the negative impacts in the feed supply for ruminants in the Brazilian Northeast region, due to seasonality in forage availability, as well as in the reducing of cost by providing concentrated feedstuffs. Among the species, mesquite pods (Prosopis juliflora SW DC) and spineless cactus (Opuntia and Nopalea) are highlighted for tolerating the drought and producion in periods where the forage is scarce, and have high nutritional value and also are well accepted by the animals. However, its use in animal diets requires a knowledge about its composition to prepare balanced diets. However, farmers usually do not use feed composition analysis, because their high cost and time-consuming. Thus, the Near Infrared Reflectance Spectroscopy in the (NIRS) is an important alternative to traditional methods. The objective of this study to develop and validate predictive models of the chemical composition of mesquite pods and spineless cactus-based NIRS spectroscopy, scanned in two different spectrometers and sample processing. Mesquite pods samples were collected in the states of Ceará, Bahia, Paraiba and Pernambuco, and samples of forage cactus in the states of Ceará, Paraíba and Pernambuco. In order to obtain the spectra, it was used two NIR equipment: Perten DA 7250 and FOSS 5000. sSpectra of samples were initially obtained fresh (as received) using Perten instrument, and with The Unscrambler software 10.2, a group of subsamples was selected to model development, keeping out redundant ones. The selected samples were dried and ground, and scanned again in both Perten and FOSS instruments. The values of the reference analysis were obtained by methods traditionally applied in animal nutrition laboratory to dry matter (DM), mineral matter (MM), organic matter (OM), crude protein (CP), ether extract (EE), soluble neutral detergent fiber (NDF), soluble acid detergent fiber (ADF), hemicellulose ( HEM) and in vitro digestibility of dry matter (DIVDM). The performance of the models was evaluated according to the Root Mean Square Error of Calibration (RMSEC) and cross-validation (RMSECV), coefficient of determination (R2 ) and the deviation of Ratio of performance Deviation of the models (RPD). Exploratory data analysis through spectral treatments and principal component analysis (PCA), showed that the databases were similar to each other, and may be treated asa single model for each feed - mesquite pods and cactus. Evaluating the reference results, it was observed that the variation were similar to those reported in the literature. Comparing the preprocessing of samples, the performance ofthose developed with preprocessing (dried and ground) of the sample were more robust than those built with fresh samples. The NIRS Perten device performance similar to FOSS equipment, although the latter cover a larger spectral range and with lower readings intervals. NIR technology associate do multivariate techniques is reliable to predict the bromatological composition of mesquite pods and cactus.

Dissection of the protective response elicited by the DOMV component of the 4CMenB vaccine

Neisseria meningitidis serogroup B is the major etiological agent of meningitis and life-threatening sepsis, against which two vaccines are licensed. The 4CMenB vaccine is composed of three major protein antigens (fHbp, NHBA and NadA) and detergent-extracted outer membrane vesicles (DOMV) from the NZ98/254 strain. DOMV are safe, immunogenic and able to raise bactericidal antibodies, mainly attributed to the immunodominant PorA protein. Nevertheless, DOMV offer a complex reservoir of potentially immunogenic proteins, whose relative contribution in protection is still poorly characterized. By testing antisera from vaccinated infants in serum bactericidal assay, we observed that the addition of DOMV in the vaccine formulation enhanced breadth of coverage compared to recombinant proteins alone against a panel of 11 meningococcal strains mismatched for the vaccine antigens. To unravel the DOMV components involved in such protection, 30 DOMV antigens were cloned and expressed in Escherichia coli as recombinant proteins and/or in vesicles to maintain their native conformation. Samples obtained were both included in tailor-made protein-microarrays to immunoprofile the antibody repertoire raised by DOMV-containing formulations and were individually used for mouse immunization studies to assess their ability to induce bactericidal antibodies. The protein-array immunosignature of mouse DOMV/4CMenB antisera unveiled a subset of 8 DOMV-reactive proteins potentially responsible for the additional protective responses. The antisera derived from mouse immunizations showed high levels of antibodies and recognized the corresponding antigen across different meningococcal strains. Among the protein-array reactive antigens, OpcA, NspA and PorB induced antibodies able to kill 10 of the 11 genetically diverse meningococcal strains and the specificity of the protective role of OpcA and PorB was also confirmed in 4CMenB infant vaccinee sera. In conclusion, we identified additional PorA-independent antigens within DOMV involved in broadening the coverage of 4CMenB, thus supporting the key role played by vesicles in this multivalent formulation.

Safe and Collaborative Navigation & Interaction With Mobile Manipulators in Domestic Appliance Test Labs

Safe collaboration between a robot and human operator forms a critical requirement for deploying a robotic system into a manufacturing and testing environment. In this dissertation, the safety requirement for is developed and implemented for the navigation system of the mobile manipulators. A methodology for human-robot co-existence through a 3d scene analysis is also investigated. The proposed approach exploits the advance in computing capability by relying on graphic processing units (GPU’s) for volumetric predictive human-robot contact checking. Apart from guaranteeing safety of operators, human-robot collaboration is also fundamental when cooperative activities are required, as in appliance test automation floor. To achieve this, a generalized hierarchical task controller scheme for collision avoidance is developed. This allows the robotic arm to safely approach and inspect the interior of the appliance without collision during the testing procedure. The unpredictable presence of the operators also forms dynamic obstacle that changes very fast, thereby requiring a quick reaction from the robot side. In this aspect, a GPU-accelarated distance field is computed to speed up reaction time to avoid collision between human operator and the robot. An automated appliance testing also involves robotized laundry loading and unloading during life cycle testing. This task involves Laundry detection, grasp pose estimation and manipulation in a container, inside the drum and during recovery grasping. A wrinkle and blob detection algorithms for grasp pose estimation are developed and grasp poses are calculated along the wrinkle and blobs to efficiently perform grasping task. By ranking the estimated laundry grasp poses according to a predefined cost function, the robotic arm attempt to grasp poses that are more comfortable from the robot kinematic side as well as collision free on the appliance side. This is achieved through appliance detection and full-model registration and collision free trajectory execution using online collision avoidance.

Touristic water demand: analysis and validation of drinking water consumption data and hotel characterization in Benidorm (Spain)

The work analyses the tourist water demand in Benidorm, a sun-and-sand destination ranked fourth in Spain by number of visitors, where tourism competes with local residents, nature, agriculture and industrial sectors for scarce water resources. In particular, we have studied the correlation between the water consumption of 83 hotels in Benidorm and their characteristics and services which can impact water use. For this purpose, we have examined the water consumption billed, by the water utility company HIDRAQUA in the period January 2010 - October 2022, to the tourist structures in the municipality of Benidorm, and we have explored the hotels’ features, thanks to the collaboration of the tourism and hotels association HOSBEC. To give a better understanding and contextualization of our analysis we first described explained the of the complex water supply system and the efforts that have been made to reduce the threat posed by the peculiar climate conditions of the region. We saw that the water consumption per guest has slightly decreased in the recent years and that the tourist flux has increased: the global pandemic posed a stop to travels for more than one year, but now both the tourist flux and the tourist water consumption are reaching pre-pandemic level. We found that larger hotels, and in particular the ones opened all the year, that probably tend to offer more water-demanding service with respect to the seasonal ones, have higher water consumption per bed. From the analysis of the role of the different hotel characteristics over the water demand patterns, we found that water use increases with the increase in the hotel category and in the ratio between the surface area of the swimming pool and hotel size (number of beds). Other factors impacting the consumption are the presence of an on-site laundry for washing the hotel linen, the garden, and the implementation of environmental policies for water-saving.
