Full textIn the three decades that preceded the entrance of Italy in the European conflict (whose first act of war it was the occupation of the Albanian port of Vlore and the nearby island of Saseno) a substantial travel literature (made by intellectuals, politicians publicists) flooded the publishing market, helping to volgarizzare to the general public the reasons for so much interest in the history of that part of the Balkan peninsula. The recovery of these writings (essential to rebuild the contents of the message conveyed at the time) and their integration with the theorized by army and navy allows you to analyze the logic and purposes of a long-term issue. Most importantly, it allows you to understand what role played the possession of Vlore and Albania within the wider picture of Italian hegemony on the Adriatic and the Mediterranean, highlighting the existence of two different addresses of so-called "Adriatic question": the one linked exclusively to Dalmatia; the other decided not to compromise on both sides.

Full textThe objective of this study was to evaluate the performance, carcass yield and commercial cuts fed pelleted diets containing different ratios of valine / isoleucine during the growing and final (22-42 days) phase of these animals. I was used 630 one day old male cobb 500 broiler chicks during 1-22 days of age, the birds were fed a common basal diet at 22 days the birds were weighed and distributed in a completely randomized design with factorial 3x3 (nine combinations of levels of valine and isoleucine). Broilers were submitted to the following experimental treatments: T1 - ration with respect valine / isoleucine and lysine 0.75% / 0.67% lysine; T2 - ration with respect valine / isoleucine and lysine 0.75% / 0.71% lysine; T3 - ration with respect valine / lysine and isoleucine 0.75% / 0.75% lysine; T4 - ration with respect valine / lysine and isoleucine 0.79% / 0.67% lysine; T5 - tion with respect valine / isoleucine isoleucine and 0.79% / 0.71% lysine; T6 - tion with respect valine / isoleucine isoleucine and 0.79% / 0.75% lysine; T7 - tion with respect valine / isoleucine isoleucine and 0.83% / 0.67% lysine; T8 - tion with respect valine / isoleucine isoleucine and 0.83% / 0.71% lysine and T9 - tion with respect valine / isoleucine isoleucine and 0.83% / 0.75% lysine. The characteristics evaluated were weight gain, feed intake, feed conversion and carcass yield and animal commercial cuts. There was a significant interaction between the factors for all characteristics evaluated, except for weight at 28 days. The best results in characteristics were evaluated for birds receiving (0.83% of valine and isoleucine 0.75%), except for body weight and weight gain at 42 days, in which the best results were obtained the animals receiving (0.83% and 0.75% of valine for isoleucine)

Full textThis study was to evaluate optimal levels of digestible valine. Three trials were conducted with broiler chickens of Cobb in the initial phase (1-14 days), growth (14-28 days) and termination (28-42 days), with tests performed separately for each phase, based on the method dose-response. For tests 1 to 14 days and 14 to 28 days, 672 animals it were distributed in a completely randomized in eight treatments (seven levels of valine and 1 control), with 7 replicates, each replicate consisting of 12 birds but the test of 28 to 42 days 560 chickens were used, equally distributed as in previous trials in 8 treatments with 7 replicates of 10 birds each. Basal diets were formulated by the dilution technique, deficient in valine, containing levels of energy, minerals and vitamins as recommended by Rostagno et al. (2005), for each phase. The recommended levels of digestible valine for each phase, obtained in this study were based on responses from CA. The recommendations obtained by the dose response are 0.917, 0.905 and 0.783% of digestible valine for broilers from 1-14 days, 14-28 and 28-42 days of age, respectively.

Deuteration allows the identification of several species of vibrations, through the comparison of vibrational spectra of the deutered and hydrogeneted samples. In this work we base studied the vibrational properties of L-valine-d8 (99,8 % atom % D) through the Raman spectroscopy technique. At first, the assignment of all Raman active vibratonal mades of L-valine was revisited, and a comparison with a previous work was done. In particular, several bands associated to stretching of NH_3^+ and stretching of CH3, among others, which are observed in the interval 2000 – 2400 cm-1 were assigned. In the second part of the work, again using Raman spectroscopy, it was studied the vibrational modes of the crystal in the temperature range 100 – 300 K. It is known from literature that hydrogenated L-valine undergoes a phase transition at about 110 K. It also known that in deuterated crystals hydrogen bands - through Ubbehlode effect – tend to be less strange and, as a consequence, a comparative analyses between the deuterated and hydrogenated samples is very important. In a previous work on L-alanine it was observed that deutaration induces a new phase at low temperatures. In the investigation on L-valine, at least in the temperature range studied, it was not possible to note any change in the Raman spectra which could be associated to a structural phase transition. Both in the external modes region any great change is verified. As a consequence, we can infer that L-valine-d8 is stable between 100 and 300 K. A discussion about the difference behaviors at low temperatures of L-valine and L-alanine (both deuterated and hydrogenated) is also furnished in the present work.
A deuteração de uma determinada amostra permite fazer a identificação de vários tipos de vibrações, comparando-se o espectro vibracional com o de uma amostra hidrogenada. Neste trabalho estudou-se o comportamento vibracional da L-valina-d8 (99,8 átomo % D) através da técnica de espectroscopia Raman. Inicialmente revisitou-se o assinalamento de todos os modos vibracionais ativos no Raman, comparando-se com um estudo previamente realizado. Em particular foram identificadas diversas bandas associadas a vibrações do tipo estiramento do NH3+ e estiramento do CH3, entre outros, que são observadas na região entre 2000 e 2400 cm-1. Na segunda parte do trabalho foi realizado um estudo via espalhamento Raman dos modos vibracionais do cristal no intervalo de temperatura entre 100 e 300 K. Sabe-se da literatura que a L-valina hidrogenada apresenta uma transição de fase em torno de 110 K. Uma vez que nos cristais deuterados as ligações de hidrogênio via o efeito Uhbehlode tendem a ser mais fracas, uma análise comparativa entre as amostras hidrogenada e deuterada se faz necessário. Em particular, num estudo realizado na L-alanina descobriu-se que a deuteração induz a formação de uma nova fase em baixas temperaturas. No caso da L-valina, pelo menos no intervalo de temperatura investigado, não foi possível observar nenhuma mudança nos espectros Raman que pudessem ser associadas a uma transição de fase estrutural. De fato, tanto na região dos modos externos, quanto na região dos modos internos nenhuma grande modificação é verificada. Isso implica que a estrutura da L-valina-d8 é estável no intervalo de 100-300 K. Uma discussão acerca da diferença do comportamento a baixas temperaturas dos cristais de L-valina e de L-alanina nas formas hidrogenadas e deuteradas é também fornecida no presente trabalho.

The valine is part of the branched chain amino group together with leucine and isoleucine, and has an important structural role and anabolic. Two experiments were conducted in order to determine the requirement of valine for fingerlings and juveniles of tilapia, by assessing the growth performance, and analysis of chemical composition of housing, hematological and biochemical blood, and white muscle morphometric. In the first experiment were used 270 tilapia fingerlings whit initial average weight of 1.57 ± 0.05 g total initial length of 4.16 ± 0.46 cm, distributed in completely randomized design with six treatments and three replications, using 18 boxes with 250 liter of capacity during the experimental period of 79 days. In the second experiment were used 216 tilapia juveniles with initial average weight of 21.40 ± 0.42g and initial total length of 10.07 ± 1.00 cm, distributed in 18 boxes whit 500 liters of capacity during the experimental period of 77 days. The treatments consisted of diets with increasing concentrations of valine, being for fingerlings (0.82, 0.86, 0.98, 1.04, 1.10 and 1.26% valine) and juvenile (0.54, 0.63, 0.72, 0.81, 0.90 and 0.99% valine). Feed has been held four times a day to apparent satiation. Evaluated the growth performance (weight gain, feed conversion, daily weight gain, protein efficiency ratio, condition factor, survival, protein retention efficiency, visceral fat, liver somatic index, specific growth rate and uniformity of the lot) for fingerlings and juveniles; fish proximate composition (moisture, crude protein, lipids and ash) for fingerlings and juveniles; hematological and biochemical indices of the blood (hemoglobin, erythrocytes count, hematocrit percent, total leukocytes, total thrombocytes, plasma protein, glucose, triglyceride and cholesterol) for juvenile and distribution of muscle fibers to fingerlings and juveniles. There was no statistical difference (P>0.05) for the performance variables, chemical composition and histology between the different treatments evaluated to fingerlings. For juvenile tilapia, on the performance were observed significant differences (P<0.05) between treatments for weight gain, daily weight gain and feed conversion. For hematological and biochemical parameters of blood, there were significant differences (P<0.05) between treatments for hemoglobin, total triglycerides and total cholesterol. Significant differences in the chemical composition of fish and frequency of muscle fibers were observed. It is concluded that the nutritional requirements are met with valine 0.82% valine in the diet (2.65% valine crude protein) for minnows and 0.81% of valine in the diet (2.90% valine crude protein) for juvenile Nile tilapia.
A valina faz parte do grupo de aminoácidos de cadeia ramificada, juntamente com a leucina e isoleucina, e possui importante papel estrutural e anabólico. Foram realizados dois experimentos com o objetivo de determinar a exigência nutricional de valina para alevinos e juvenis de tilápias do Nilo, por meio da avaliação do desempenho zootécnico, e das análises de composição química da carcaça, perfil hematológico e bioquímico do sangue, e da morfometria do músculo esquelético. No primeiro experimento, foram utilizados 270 alevinos de tilápia com peso médio inicial de 1,57 ± 0,05 g e comprimento total inicial de 4,16 ± 0,46 cm, distribuídos em um delineamento inteiramente ao acaso com seis tratamentos e três repetições, utilizando 18 caixas com 250 litros de capacidade, durante período experimental de 79 dias. No segundo experimento, foram utilizados 216 juvenis de tilápia com peso médio inicial de 21,40 ± 0,42 g e comprimento total inicial de 10,07 ± 1,00 cm, distribuídos em um delineamento inteiramente ao acaso com seis tratamentos e três repetições, utilizando 18 caixas com 500 litros de capacidade, durante período experimental de 77 dias. Os tratamentos consistiam em dietas com concentrações crescentes de valina, sendo para alevinos (0,82; 0,86; 0,98; 1,04; 1,10 e 1,26 % de valina na dieta) e para juvenis (0,54; 0,63; 0,72; 0,81; 0,90 e 0,99 % de valina na dieta). A alimentação foi realizada quatro vezes ao dia até a saciedade aparente. Avaliou-se o desempenho zootécnico (ganho em peso, conversão alimentar aparente, ganho em peso diário, taxa de eficiência proteica, fator de condição, sobrevivência, eficiência de retenção proteica, gordura visceral, índice hepatossomático, taxa de crescimento específico e uniformidade do lote) para alevinos e juvenis; a composição centesimal dos peixes (umidade, proteína bruta, extrato etéreo e cinzas) para alevinos e juvenis; os índices hematológicos e bioquímicos do sangue (taxa de hemoglobina, contagem de eritrócitos, percentual de hematócritos, leucócitos totais, trombócitos totais, proteína plasmática, glicose, triglicerídeos e colesterol) para juvenis e a distribuição das fibras musculares para alevinos e juvenis. Não houve diferença estatística (P>0,05) para as variáveis de desempenho, composição centesimal e histologia entre os diferentes tratamentos avaliados para alevinos. Para os juvenis de tilápia, no desempenho zootécnico observaram-se diferenças significativas (P<0,05) entre os tratamentos para o ganho em peso, ganho em peso diário e conversão alimentar aparente. Para os parâmetros hematológicos e bioquímicos do sangue, observaram-se diferenças significativas (P<0,05) entre os tratamentos para taxa de hemoglobina, triglicerídeos totais e colesterol total. Não foram observadas diferenças significativas para a composição centesimal dos peixes e frequência das fibras musculares. Conclui-se que as exigências nutricionais de valina são atendidas com 0,82% de valina na dieta (2,65% de valina da proteína bruta) para alevinos e 0,81% de valina na dieta (2,90% de valina) para juvenis de tilápias do Nilo.

Full textThe present research aims to examine the concept of mood developed by students from 1st to 4th year in Secondary Compulsory Education, and to analyse the role of metalinguistic activity in learning grammar. It departs from the hypothesis that the student can observe and reflect on language in an active and meaningful way to understand how the linguistic system works. By doing so they will improve usage. Several studies (Chartrand, 1996; Fisher, 2004) note the fact that students have difficulties to attain an optimal level of metalinguistic competence. This construct is understood as the ability to acquire a conscious, explicit knowledge of the linguistic system from observation, description and, in short, reflection about language. With respect to the theoretical framework, this study is based on research about students’ metalinguistic activity and the development of knowledge of grammar (Culioli, 1990; Karmiloff-Smith, 1994; Gombert, 1992; Camps, 2000; Cams et al., 2005). Additionally, the study takes into account research on the students’ construction of grammatical concepts (Camps et al. 2001; Notario, 2001; Durán, 2008), on the challenges faced by grammar teaching (Camps, 2009; Fisher, 2004). Furthermore, the author considers the studies that deepen in the knowledge about the grammatical content selected in this study; that is, the subjunctive mood in Spanish (Bosque, 1996; Luquet, 2004; Pérez Saldanya, 1999). Finally, the study analyzes some research on how textbooks deal with the teaching of grammar and analyses the current curriculum. The research design is based on contrast and comparison activity of sentences that alternate Indicative and Subjunctive in Spanish. The activity that the students carried out in small groups consisted of comparing four pairs of sentences in which the only difference between the two sentences in each pair was the verbal mood. The students had to provide a written response regarding the difference that they perceived between the sentences in order to find out a) whether they distinguish between the different uses of the indicative and the subjunctive and b) whether they are able to describe what the difference between moods. The analysis yielded the following results. First, students in all classes, from younger to older, demonstrated linguistic competence as language users, which allowed them to clearly distinguish the different semantic and pragmatic uses of the Indicative and Subjunctive forms. However at the same time, they also demonstrated great difficulty in discussing the difference between the two moods, showing a very inaccurate use of metalanguage. Second, there was no evidence of the students having constructed a concept of mood that would be useful and functional for understanding the modal system. The term did not even appear spontaneously in their writing. Finally, the sentence comparison task seemed to be an activity that promotes students’ reflection and forces them to see language in a less automatic way, that is, to see it as an object of study. At the same time, this task highlighted the difficulties they faced during a reflection activity to which they did not seem to be used.

Dois experimentos foram realizados com o objetivo de se avaliar o desempenho, a qualidade dos ovos, o balanço de nitrogênio, a concentração de aminoácidos plasmáticos e o custo da ração de poedeiras formuladas à base de milho e farelo de soja, com diferentes níveis de isoleucina (0,55%; 0,62% e 0,70%) e de valina digestíveis (0,60%; 0,67% e 0,75%). Foram utilizadas 640 poedeiras Isa Brown, com 40 semanas de idade, distribuídas em um delineamento inteiramente casualizado, em esquema fatorial 3 x 3 + 1 (3 níveis de isoleucina digestíveis, três níveis de valina digestíveis e + um tratamento controle), totalizando 10 tratamentos com oito repetições de oito aves cada. A porcentagem de postura e o peso dos ovos sofreram influência negativa e positiva, respectivamente, do tratamento com 17% de proteína bruta. Independente do nível de valina, o tratamento com 0,70% de isoleucina apresentou menor consumo de ração e as melhores conversões alimentares por kg e dúzia de ovos. A unidade Haugh dos ovos no tratamento com 0,67% de valina na dieta foi maior do que nos ovos do tratamento com 0,60%. O tratamento com 0,70% de isoleucina proporcionou menor porcentagem de gema e maior porcentagem de albúmen. As aves alimentadas com o tratamento controle ingeriram e excretaram maior quantidade de nitrogênio. De acordo com os níveis plasmáticos obtidos, a isoleucina não demonstrou efeito antagônico com a valina, e o aumento da suplementação com isoleucina e valina elevaram os níveis plasmáticos destes aminoácidos. Conclui-se que a porcentagem de postura, peso dos ovos, ingestão e excreção de nitrogênio são influenciados pela redução protéica da dieta e os níveis de 0,70 % de isoleucina e 0,67% de valina melhoraram a qualidade dos ovos, com custo por ovo semelhante ao tratamento com 17% de proteína bruta
Two experiments were conducted to evaluate performance, egg quality, nitrogen balance, the concentration of plasma amino acids and the food cost of diets based on corn and soybean meal, with different isoleucine and valine levels with 0.55%, 0.62% and 0.70% isoleucine, 0.60%, 0.67% and 0.75% valine. A total of 640 ISA Brown hens, 40 weeks old, distributed in a completely randomized design, in factorial 3 x 3 + 1 (three digestible isoleucine levels, three digestible valine and a control treatment), totaling 10 treatments with eight replications and eight birds each. The egg production and egg weight were influenced by the control treatment. Regardless of the level of valine, treatment with 0.70% isoleucine showed lower feed intake and the best feed conversion per kg and a dozen eggs. The Haugh unit eggs treatment with 0.67% of valine in the diet was higher than in eggs treatment with 0.60%. Treatment with 0.70% isoleucine resulted in a smaller percentage of yolk and albumen higher percentage. The birds fed the control diet ingested and excreted larger amounts of nitrogen. According to the amino acids plasmatic levels obtained, isoleucine showed no antagonistic effect with valine, and increased supplementation isoleucine and valine increased the plasma levels of these amino acids. We conclude that the egg production, egg weight, intake and nitrogen excretion are influenced by reduced protein diet and levels of 0.70% and 0.67% of isoleucine to valine improved egg quality, cost egg by similar treatment with 17% crude protein

Aminoácidos formam a estrutura conforme das proteínas. Acredita-se que aminoácidos possam ter chegado a Terra trazidos por meteoros e meteoritos, e por isso, possam ter desempenhado um papel importante no surgimento da vida no planeta. A análise da fotodegradação e da estrutura eletrônica dos aminoácidos em fase gasosa constitui um ponto partida na compreensão da origem molecular da vida. Aminoácidos na forma gasosa são obtidos por aquecimento. A degradação térmica de um aminoácido pode produzir resultados incorretos quando espectros de fotoelétrons e de tempo de vôo são analisados. Nesta perspectiva, realizamos um estudo criterioso da degradação termicamente induzida do ?-aminoácido DL-Valina quando volatizado em diferentes regimes de temperatura. Estabelecemos critérios para evitar a decomposição termicamente induzida na amostra, bem como, descrevemos as mudanças nos espectros de massa produzidos, que são comumente tomados em altas temperaturas. Espectros de PEPICO registrados utilizando um feixe de fótons na região de 11.2 - 21.5 eV, nos permitiram analisar a produção dos fragmentos iônicos desta molécula, descrevendo os seus canais de dissociação. As curvas de produção parcial de íons foram construídas usando um novo método de cálculo das áreas dos picos no espectro de tempo de vôo. Pela primeira vez, são apresentados os potenciais de surgimento de oito fragmentos para esta molécula. Somado a isso, um espectro de fotoelétrons de valência da fase gasosa da DL-Valina foi obtido com o auxílio de uma lâmpada de He I (h? =21.217 eV) e gravado pelo Analisador de elétrons Scienta-R4000 que trabalha a altas pressões na câmara de medida. O espectro obtido contrasta com o único espectro de fotoelétrons dessa molécula citado na literatura. As energias dos orbitais de mais alta valência, calculadas pelo grupo de Simulação e Modelagem Molecular da Universidade de São Paulo (USP), são utilizadas para a análise das estruturas deste espectro. Um bom acordo foi obtido entre as predições teóricas e os resultados experimentais. _________________________________________________________________________________ ABSTRACT
Amino acids are the building blocks of proteins. It is believed that amino acids may have come to Earth brought by meteors and meteorites, and therefore, may have played an important role in the emergence of life on the planet. The photodegradation and electronic structure analysis of amino acids in gas phase is a starting point to understand the molecular origins of life. Amino acids in gaseous form are obtained by heating. The thermal degradation of an amino acid may produce incorrect results when the photoelectron and time-of-flight spectra are analyzed. By this perspective, we made a careful study of heat-induced degradation of the -amino acid DL-Valine when volatilized in different temperature regimes. We establish criteria to avoid decomposition thermally induced in the sample and we describe the changes in the mass spectra produced, which are commonly taken at high temperatures. PEPICO spectra recorded using a beam of photons in the region 11.2-21.5 eV allowed us to analyze the ionic fragments yield of this molecule, describing the dissociation channels. The partial ion yield curves were constructed using a new method of calculation of peak areas in the time-of-flight spectrum. For the first time, appearence energies of eight fragments for this molecule are presented. Added to this, a valence photoelectron spectra from the gas phase of the DL-valine is obtained with the aid of a lamp He I (h = 21.217 eV) and recorded by the electron analyzer Scienta-R4000 that runs at high pressures in the main chamber. The spectrum obtained contrasts with the single photoelectron spectra of this molecule reported in the literature. The highest occupied molecular orbitals, calculated by the group of Simulation and Molecular Modeling of University of São Paulo (USP), are used to analyze the structures in this spectrum. A good agreement was obtained between the theoretical predictions and experimental results.

Resumo: Dois experimentos foram realizados com o objetivo de se avaliar o desempenho, a qualidade dos ovos, o balanço de nitrogênio, a concentração de aminoácidos plasmáticos e o custo da ração de poedeiras formuladas à base de milho e farelo de soja, com diferentes níveis de isoleucina (0,55%; 0,62% e 0,70%) e de valina digestíveis (0,60%; 0,67% e 0,75%). Foram utilizadas 640 poedeiras Isa Brown, com 40 semanas de idade, distribuídas em um delineamento inteiramente casualizado, em esquema fatorial 3 x 3 + 1 (3 níveis de isoleucina digestíveis, três níveis de valina digestíveis e + um tratamento controle), totalizando 10 tratamentos com oito repetições de oito aves cada. A porcentagem de postura e o peso dos ovos sofreram influência negativa e positiva, respectivamente, do tratamento com 17% de proteína bruta. Independente do nível de valina, o tratamento com 0,70% de isoleucina apresentou menor consumo de ração e as melhores conversões alimentares por kg e dúzia de ovos. A unidade Haugh dos ovos no tratamento com 0,67% de valina na dieta foi maior do que nos ovos do tratamento com 0,60%. O tratamento com 0,70% de isoleucina proporcionou menor porcentagem de gema e maior porcentagem de albúmen. As aves alimentadas com o tratamento controle ingeriram e excretaram maior quantidade de nitrogênio. De acordo com os níveis plasmáticos obtidos, a isoleucina não demonstrou efeito antagônico com a valina, e o aumento da suplementação com isoleucina e valina elevaram os níveis plasmáticos destes aminoácidos. Conclui-se que a porcentagem de postura, peso dos ovos, ingestão e excreção de nitrogênio são influenciados pela redução protéica da dieta e os níveis de 0,70 % de isoleucina e 0,67% de valina melhoraram a qualidade dos ovos, com custo por ovo semelhante ao tratamento com 17% de proteína bruta
Abstract: Two experiments were conducted to evaluate performance, egg quality, nitrogen balance, the concentration of plasma amino acids and the food cost of diets based on corn and soybean meal, with different isoleucine and valine levels with 0.55%, 0.62% and 0.70% isoleucine, 0.60%, 0.67% and 0.75% valine. A total of 640 ISA Brown hens, 40 weeks old, distributed in a completely randomized design, in factorial 3 x 3 + 1 (three digestible isoleucine levels, three digestible valine and a control treatment), totaling 10 treatments with eight replications and eight birds each. The egg production and egg weight were influenced by the control treatment. Regardless of the level of valine, treatment with 0.70% isoleucine showed lower feed intake and the best feed conversion per kg and a dozen eggs. The Haugh unit eggs treatment with 0.67% of valine in the diet was higher than in eggs treatment with 0.60%. Treatment with 0.70% isoleucine resulted in a smaller percentage of yolk and albumen higher percentage. The birds fed the control diet ingested and excreted larger amounts of nitrogen. According to the amino acids plasmatic levels obtained, isoleucine showed no antagonistic effect with valine, and increased supplementation isoleucine and valine increased the plasma levels of these amino acids. We conclude that the egg production, egg weight, intake and nitrogen excretion are influenced by reduced protein diet and levels of 0.70% and 0.67% of isoleucine to valine improved egg quality, cost egg by similar treatment with 17% crude protein

Foram utilizadas 1440 aves, alocadas em unidades experimentais distribuídas em delineamento inteiramente ao acaso, divididas em dois experimentos, um com cinco níveis de valina digestível (0,74; 0,81; 0,88; 0,95 e 1,02%) realizado em dois ensaios, e outro, com cinco níveis de isoleucina digestível (0,64; 0,70; 0,76; 0,82 e 0,88%) realizado em dois ensaios, ambos com oito repetições e oito aves por repetição. As dietas experimentais foram formuladas à base de milho e farelo de soja, contendo 2900 kcal de energia metabolizável e 18% de proteína bruta. A Ração e água foram fornecidos à vontade durante todo o período experimental. As características avaliadas foram consumo de ração, ganho de peso, taxa de postura, peso médio do ovo, massa dos ovos, conversão alimentar por massa do ovo e por dúzia de ovos, peso relativo e absoluto da gema, do albúmen e da casca, além da unidade de Haugh. Observou-se que para codornas japonesas em postura deve-se utilizar dietas com 0,74% de valina e 0,64% de isoleucina digestíveis para a maximização de sua função produtiva. O aumento proporcional dos aminoácidos valina e isoleucina digestíveis pode melhorar o ganho de peso das aves, no entanto a qualidade dos ovos diminui.

Full textOnly limited effort is used for selecting procurement form in construction projects. Minor use of resources and a lack of systematic approach is highlighted in many research papers. The selection is typically based on client’s previous experiences when the selected procurement form tends to be a familiar and safe choice. Systematic ways to carry out the selection have been studied internationally for decades. Numerous approaches are developed, but none has stood out clearly over the others. Typical problems of invented selection models have been too narrow point of view, poor user-friendliness and requirements of mathematical know-how. The main purpose of this Master’s Thesis is to develop a systematic model for the selection of a procurement form that takes the above-mentioned challenges into account. Constructive research is used to find a solution to a practical problem of delivering procurement form selection in real life projects. Development of the model is approached at first through literature review by observing the differences of procurement form variations, used selection criteria and selection methods. (RQ1). Results from the theoretical research are compared and combined with empirical analysis and observations. As a result of this, a systematic selection process is developed for the selection of a procurement form in unique building and construction projects (RQ2). Lastly, the practical applicability of the proposed model is tested in the procurement form selection process of a real project (RQ3). Procurement forms consist of three different entities: contract form, payment basis and procurement procedure. Contract form has the most influencing role and it often defines the chosen payment basis and procurement procedure. The selection of procurement form is affected by multiple factors. These factors can be called as selection criteria that can be divided to four main groups: project features, client’s attributes, client’s objectives and external environment. Every one of these entities approach the selection of a procurement form from a different perspective. Due to this, results obtained from different groups cannot be combined without contradictions. The selection of a procurement form should be approached as a wider selection process. Client’s strategic targets, procurement strategy and risk strategy affect the appropriateness of different procurement form options and also the client’s objectives. The client’s objectives do not include only objectives for a project but also objectives for the whole procurement and the relationships between different actors in a project. All of these three perspectives should be identified and dealt with before continuing further to the comparison of different procurement forms. After this the basic information of the observed project must be gathered. When understanding the general view, project-related modifications and restrictions can be made to the selection model. The selection model deals with all of the four identified perspectives to the procurement form selection. First, project features are examined and compared with assessed values to seven procurement form options. Based on these results and observations, a few procurement forms that include both contract form and payment basis are selected for further evaluation. Suitability of these procurement form options is evaluated from the perspectives of client’s attributes, client’s objectives and external environment. Lastly, the results from different perspectives are compared together and a recommendation of the most suitable procurement form for the observed project is made. The developed selection process can be especially used as a structure of carrying out the procurement form selection. Validity of the research is generally great when combining the results from reliability examination and case-validation. Used selection criteria and entities can also be generalized to international context. However, examined procurement forms and their differences are mostly limited to national context

Full textAcrylonitrile is an intermediate of the chemical industry, used for synthesis ofnumerous polymers and coating. It is produced by ammoxidation of propene, which becomes rare andexpensive. This project aimed to develop new catalysts based on nitrides and oxynitrides allowing touse abundant and cheaper propane as starting product. Propane presents an industrial interest in viewof its economical potential and durability and because its exploitation as chemical precursor wouldallow to use natural resources more efficiently. Numerous oxynitrides based catalysts have beenprepared and tested as catalysts. Some of them were shown to be unstable in reaction conditions, likeVZrON, MoVON, and LaVON, some were shown to be stable but either weakly active or notselective like MgTaVON and VZrAlON. The study has been focused on VAlON oxynitrides. Thesecatalysts have been characterized by several techniques, like XRD, XES, XANES, XPS, 27Al-NMR,NH3 and CO2-TDP and the influence of several parameters on their catalytic properties have beenstudied. The results of these studies have confirmed that these catalysts were very efficient for thereaction and shown that the optimal catalyst had a V/Al ratio around 0.30 with an average oxidationstate of vanadium in catalytic condition around 3.8. A nitridation site has been proposed correspondingto OxV-NH2--AlO3 species. Finally a new preparation method has been discovered with the synthesisof an oxalate of vanadium and aluminum complex, which is decomposed by ozonation, and nitrided inreaction conditions. This catalyst showed improved activity and selectivity compared to coprecipitatedcatalysts

In this work, we present a study of the Raman scattering of DL-valine crystals (C5H11NO2) at room temperature under high hydrostatic pressures conditions using the spectral range of 40-3200 cm-1. Based on previous studies using Raman spectroscopy on crystals of DL-valine and other amino acids such as L-valine, L-isoleucine and L- asparagine, we proposed the classification of the bands in different vibration modes. The Raman spectrum obtained as function of pressure suggests that DL-valine suffered two structural phase transitions by 19,4 GPa. The first transition phase of between 1,4 GPa and 1,8 GPa where we observed the disappearance of three modes, one network mode and two internal modes classified as rocking of NH3+ and symmetric stretching of CH3, vs (CH3). The second phase transition of between 7,8 GPa and 8,8 GPa, where we observe the unfolding of a network mode, the disappearance of the internal mode associated with skeletal deformation, d(esk) and the splitting designated as CH2, v(CH2).

Objetivou-se com esta pesquisa: 1) determinar as exigências de mantença de valina (Val), isoleucina (Ile) e triptofano (Trp) digestível utilizando diferentes sistemas de unidade; 2) avaliar as respostas de aves reprodutoras pesadas para diferentes ingestões de Val, Ile e Trp, determinar a eficiência de utilização e desenvolver um modelo fatorial; 3) calcular a ingestão ótima econômica de Val, Ile e Trp para aves reprodutoras pesadas utilizando o Modelo de Reading; 4) determinar as exigências de arginina digestível para manutenção utilizando diferentes sistemas de unidades; avaliar as respostas de aves reprodutoras pesadas para diferentes ingestões de arginina, estimar os parâmetros do Modelo de Reading pelo método da simulação e equação para aves reprodutoras pesadas e calcular a ingestão ótima econômica de arginina, considerando a relação entre custo-benefício e a variabilidade da população. Para o objetivo 1 foram realizados três ensaios utilizando 144 galos Cobb 500. A exigência de mantença foi obtida pela relação entre a ingestão do aminoácido e o nitrogênio retido. Os diferentes sistemas de unidade foram: mg/kg de peso corporal, mg/kg de peso metabólico e mg/kg de peso proteico. Para o objetivo 2 foram realizados três ensaios utilizando 192 aves reprodutoras pesadas. Os dados obtidos foram ingestão do aminoácido (IAA), peso corporal (PC) e massa de ovo (MO). O modelo modificado para calcular as exigências dos aminoácidos foi: IAA=[AAm×(PC×0,196)0,73]+[(Novo×MO×AAovo)/k], onde AAm é o aminoácido para mantença, Novo é o nitrogênio do ovo, AAovo é o aminoácido do ovo e k é a eficiência de utilização. Para o objetivo 3 utilizou-se os dados de AAI, MO e PC do objetivo 2 que foram ajustados pelo modelo de Reading. Para determinar as exigências dos aminoácidos pelo método da simulação foram utilizados 10.000 aves. Para o objetivo 4 foram realizados dois ensaios, o primeiro utilizando 42 galos Ross e o segundo utilizando 64 aves reprodutoras pesadas Ross. Os procedimentos utilizados foram semelhantes aos objetivos 1, 2 e 3. As conclusões obtidas foram: A exigência de manutenção é mais adequadamente expressa como teor de proteína corporal. A predição do modelo foi melhorado utilizando os coeficientes estimados com unidades fisiologicamente relevantes. O modelo de Reading pode ser utilizado para estimar as ingestões ótimas de aminoácidos para galinhas sob diferentes cenários genéticos e econômico e, dependendo dos ingredientes disponíveis e seus preços, o custo de cada um dos aminoácidos pode variar.
The objective of this research were: 1) determine the requirements for maintenance of valine (Val), isoleucine (Ile) and tryptophan (Trp) digestible using different unit systems; 2) evaluate the responses of broiler breeder hens to different intakes of Val, Ile and Trp, determine the efficiency of utilization and develop a factorial model; 3) calculate the economic optimum intake of Val, Ile and Trp for broiler breeder hens using the Reading Model; 4) determine the digestible arginine requirements for maintenance using different unit systems; evaluate the responses of broiler breeder hens to different intakes of arginine, estimate the parameters of the Reading Model by the method of simulation and equation for broiler breeder hens and calculate the economic optimum intake of arginine, considering the relationship between costbenefit and flock variability. For the objective 1 were conducted three trials using 144 Cobb 500 roosters. The requirement for maintenance was obtained by the relationship between amino acid intake and nitrogen retention. The different unit systems were: mg/kg of body weight, mg/kg of metabolic weight (BW0.75) and metabolic protein weight at maturity (BPm 0.73×u).For the objective 2 were conducted three trials using 192 Cobb 500 broiler breeder hens. The data obtained were: amino acid intake (AAI), body weight (BW) and the egg output (EO). The modified model to calculate the requirements of amino acids was: AAI=[AAm ×(BW×0.196)0.73]+[(Negg×EO×AAegg)/k] where AAm is the amino acid for maintenance, Negg is nitrogen egg, AAegg amino acid in egg, k is efficiency of utilization. For the objective 3 was used the AAI, EO and BW data from objective 2 that were adjusted by Reading Model. To determine the requirements of amino acids by the simulation method were used 10,000 birds. For objective 4 were conducted two trials, the first using 42 Ross roosters and the second trial using 64 Ross broiler breeder hens. The procedures used were similar to the objectives 1, 2 and 3. The conclusions obtained were: The maintenance requirement is more appropriately expressed as body protein content. The prediction of the model was improved using the coefficients estimated here with physiologically relevant units. The Reading Model could be used to estimate the optimum amino acid intakes for hens under different genetic and economic scenarios and depending on the ingredients available and their prices, the cost of each amino acid will vary.

In this work, we present a study of the Raman scattering of DL-valine crystals (C5H11NO2) at room temperature under high hydrostatic pressures conditions using the spectral range of 40-3200 cm-1. Based on previous studies using Raman spectroscopy on crystals of DL-valine and other amino acids such as L-valine, L-isoleucine and L- asparagine, we proposed the classification of the bands in different vibration modes. The Raman spectrum obtained as function of pressure suggests that DL-valine suffered two structural phase transitions by 19,4 GPa. The first transition phase of between 1,4 GPa and 1,8 GPa where we observed the disappearance of three modes, one network mode and two internal modes classified as rocking of NH3+ and symmetric stretching of CH3, vs (CH3). The second phase transition of between 7,8 GPa and 8,8 GPa, where we observe the unfolding of a network mode, the disappearance of the internal mode associated with skeletal deformation, d(esk) and the splitting designated as CH2, v(CH2).

Full text“The educational value of human capital”, reversion of the title of the volume of Shultz ‘63 “The Economic Value of Education”, summarizes the location of the latest research in the economics of education, which, with Heckman, come to consider the human capital as the result of a whole educational process, starting from childhood. The volume is divided into three parts. The first presents the pioneering theories of human capital developed in the 60s of last century by the three famous economists of the University of Chicago, T.W. Schultz, J. Mincer and G.S. Becker, then analyzed the rate of return, as a method for assessing the asset of education. A second section discusses the link between education and economic growth, with particular attention to the issue of school quality, dear to E.A. Hanushek, ending with the most promising lines of research in recent economics of education offered by the contributions of Dagum and Heckman. The last part, finally, discusses the relationship between economics and pedagogy. The historical-structural approach allows to highlight the change that the relationship changes over time towards a progressive autonomy of education from economy. In this process, theories of human capital have played a main role. The book does not aim to offer definitive recipes but aspires to position itself as an instrument of reflection in a field of research that has hitherto been largely neglected in pedagogy studies.

Full textA interacção da radiação de alta energia (p.ex. raios-X, raios γ, partículas α) com o meio biológico produz ao longo do percurso de ionização diversas espécies secundárias (p.ex. iões, radicais, electrões) com potencial genotóxico mais relevante do que o da radiação primária. Das espécies formadas, electrões secundários de baixas energias são as mais abundantes. Ao interagir com o meio celular, estes electrões podem causar danos directos ou indirectos nos constituintes do ADN, focando-se este trabalho no dano indirecto. Devido ao muito curto tempo de vida dos electrões livres em meio biológico, os seus efeitos podem ser simulados recorrendo a uma espécie dadora de electrões. O objectivo deste trabalho é estudar os padrões de fragmentação da alanina e valina, por colisões átomo-molécula. O padrão de fragmentação resultante é condicionado pela estrutura da molécula alvo, pela energia de colisão e pela presença do ião K+ no complexo de colisão. No presente trabalho a fragmentação da alanina e valina resulta da interacção de um feixe de potássio neutro com o alvo molecular, alanina e valina, a diferentes energias de colisão. Os fragmentos aniónicos produzidos por transferência de electrão são analisados por espectrometria de massa do tipo tempo de voo (TOF-Time of Flight). Este estudo foi efectuado para energias de colisão entre 15 e 100 eV. Para ambos os aminoácidos foram detectados fragmentos que já haviam sido observados em estudos de captura electrónica dissociativa bem como fragmentos nunca antes reportados para estas moléculas. Foram propostos mecanismos de fragmentação tendo em atenção a energia disponível na colisão e considerados os efeitos biológicos adversos resultantes da formação destes fragmentos.

Full textThe Avis aus roys, read in five manuscripts up to now, is a little-known text belonging to the mirrors forprinces literary genre. This genre teaches future princes and kings how to rule in the best possibleway. This work is inspired by Giles of Rome's De Regimine Principum and by the Liber de informationeprincipum, and seems written for a young prince from the Valois lineage around 1347 to answer to theconcerns of this period. The manuscripts remain discreet on their origins as both author and sponsors arenot being clearly identified. The future John II the Good may have required the writing of this treaty fromroyal confessor Pierre de Treigny from Burgundy to make sure his sons would conform to the image ofan ideal prince. The time seemed to be right as the Valois dynasty was not only contested but facingmilitary struggles as well. As an answer to the Crecy defeat and according to the reformers, the author ofthe Avis aus roys suggests to make a better selection for the Hôtel officers, and to increase the prince'sdignity as well as his relationship with God. Among the Avis aus roys copies, the manuscript M.456 of the Pierpont Morgan Library, which is datable to the mid-XIVth century, is the closest to the originalwritings. This copy is exceptional due to its iconographic content unequalled in the mirrors literary genre.In this codex, some parisian artists have constantly looked to highlight royalty by emphasizing theeducational aspect of the text and covering the political and military matters of the period
