Résumé :
Aims: This study aimed to evaluate the effect of deficit irrigation at different growth periods on the yield and quality of sugarcane (Saccharum spp.) first ratoon. Study Design: The study was carried out in Randomized Complete Block Design (RCBD), with three replications. Place and Duration of Study: A field experiment was conducted during two seasons, 2020-21 and 2021-22 at Guneid Sugarcane Research Center Farm, Sudan. Methodology: Irrigation deficit treatments were applied when available soil moisture content (ASMC) reached 25% in the root zone at eight different growth periods viz; DT1: first day to day 50th, DT2: day (5th - 100th), DT3: day (10th -150th), DT4: day (15th - 200th), DT5: day (20th - 250th), DT6: day (25th - 300th), DT7: day (30th - 350th) and DT8: day 35th to day 400th after ratoon establishment. These were compared with optimum irrigation (DT0) which was irrigated at 60% ASMC at the root zone. Results: The results showed that all deficit irrigation treatments (DT1 to DT8) recorded significant cane and sugar yield reduction to the control (DT0) in the two growing seasons. In this sense, DT3, DT4 and DT5 treatments have recorded the highest cane and sugar yield reduction. Moreover, irrigation deficit affected negatively the sugarcane ratoon yield parameters with low cane water productivity in DT4 and DT5 treatments. Therefore, sugarcane first ratoon must be avoided to deficit irrigation at age of 3.3 months to 10.0 months. Conclusion: According to the results sugarcane first ratoon (Variety Co 6806) established in December under the Central Sudan Agro-climatic zone (Gunied conditions) must be avoided to deficit irrigation at ratoon age of 3.3th month to age 10.0th month (at ratoon age 100 days to 300 days), because of high reduction on cane yield and sugar yield and low in water productivity.

Résumé :
Perkara korupsi pemerintah daerah di Indonesia menunjukkan tren peningkatan. Mayoritas korupsi dilakukan terhadap dana APBD, dimana sumber penerimaan APBD yang paling utama berasal dari transfer pemerintah pusat. Berdasarkan karakteristik penggunaannya, dana transfer dapat diklasifikasikan menjadi Dana Transfer Umum (DTU, yang terdiri dari DAU & DBH) dan Dana Transfer Khusus (DTK, yang terdiri dari DAK Fisik dan non Fisik). Penelitian ini dilakukan untuk melihat bagaimana pengaruh DTU dan DTK terhadap probabilitas terjadinya korupsi di daerah. Metode yang digunakan adalah regresi Zero-Inflated Poisson (ZIP). Dengan sampel 519 Pemda Kabupaten dan Kota di Indonesia pada periode 2010-2019, DTU ditemukan memiliki hubungan positif terhadap tingkat korupsi di daerah. Keleluasaan dalam mengelola anggaran DTU menjadi penyebab yang memicu peningkatan korupsi di daerah. Sedangkan DTK menunjukkan hubungan negatif dengan tingkat korupsi di daerah. Pemda tidak memiliki keleluasaan untuk menggunakan anggaran DTK untuk program lain, selain itu pengawasan dalam realisasi program DTK juga relatif lebih ketat.

Résumé :
This study researched the effects of using various nitrogen (N) conservation measures on the residual characteristics of nitrate and ammonium N in soil and the associated N uptake by cotton plants. A field experiment with six treatments was conducted, as follows, no N application (DT1), conventional N application (DT2), 60% conventional N application combined with DCD (DT3), 60% conventional N application combined with NBPT (DT4), 60% conventional N application combined with cotton straw returning (DT5), and 60% conventional N application combined with DCD, NBPT, and cotton straw returning (DT6). The results showed that the cotton straws in the DT5 treatment were beneficial for the vegetative growth of cotton seedlings. However, it was observed that the later performance of the plants in this sample was poor in terms of height, biomass, and yield of cotton. The plant height in the DT6 sample increased by 15 cm compared with those in DT1, and the soil and plant analyzer development (SPAD) values of the fourth leaf from the top of the DT6 plants were higher than those in the DT1 and DT4 samples. The DT6 plants (60% Urea + DCD + NBPT + cotton straw) increased N use efficiency by up to 47%, and no significant decrease in biomass and cotton yield was observed compared to the DT2 sample. The residual content of nitrate N in the tillage layer increased gradually over time between two rounds of drip irrigation treatment applications. Compared with the DT2 treatment, the other treatments resulted in lower residual nitrate N contents. In summary, the application of N fertilizers at a reduced rate combined with N conservation measures may increase N use efficiency and decrease the risk of non-point source N fertilizer pollution, while maintaining the cotton yield.

Résumé :
With the development of distribution networks, large amounts of distribution terminal units (DTU) are gradually integrated into the power system. However, limited numbers of maintenance engineers can hardly cope with the pressure brought about by the substantial increase of DTU devices. As DTU fault would pose a threat to the stable and safe operation of power systems; thus, it is rather significant to reduce the fault incidence of DTU devices and improve the efficiency of fault elimination. In this paper, a DTU fault analysis method using an association rule mining algorithm was proposed. Key factors of DTU fault were analyzed at first. Then, the main concept of the Eclat algorithm was illustrated, and its performance was compared with FP-growth and Apriori algorithms using DTU fault databases of different sizes. Afterwards, a DTU fault analysis method based on the Eclat algorithm was proposed. The practicality of this method was proven by experiment using a realistic DTU fault database. Finally, the application of this method was presented to demonstrate its effectiveness.

Résumé :
Studies of differential gene expression have identified several molecular signatures and pathways associated with Parkinson’s disease (PD). The role of isoform switches and differential transcript usage (DTU) remains, however, unexplored. Here, we report the first genome-wide study of DTU in PD. We performed RNA sequencing following ribosomal RNA depletion in prefrontal cortex samples of 49 individuals from two independent case-control cohorts. DTU was assessed using two transcript-count based approaches, implemented in the DRIMSeq and DEXSeq tools. Multiple PD-associated DTU events were detected in each cohort, of which 23 DTU events in 19 genes replicated across both patient cohorts. For several of these, including THEM5, SLC16A1 and BCHE, DTU was predicted to have substantial functional consequences, such as altered subcellular localization or switching to non-protein coding isoforms. Furthermore, genes with PD-associated DTU were enriched in functional pathways previously linked to PD, including reactive oxygen species generation and protein homeostasis. Importantly, the vast majority of genes exhibiting DTU were not differentially expressed at the gene-level and were therefore not identified by conventional differential gene expression analysis. Our findings provide the first insight into the DTU landscape of PD and identify novel disease-associated genes. Moreover, we show that DTU may have important functional consequences in the PD brain, since it is predicted to alter the functional composition of the proteome. Based on these results, we propose that DTU analysis is an essential complement to differential gene expression studies in order to provide a more accurate and complete picture of disease-associated transcriptomic alterations.

Résumé :
The biological importance of changes in RNA expression is reflected by the wide variety of tools available to characterise these changes from RNA-seq data. Several tools exist for detecting differential transcript isoform usage (DTU) from aligned or assembled RNA-seq data, but few exist for DTU detection from alignment-free RNA-seq quantifications. We present the RATs, an R package that identifies DTU transcriptome-wide directly from transcript abundance estimates. RATs is unique in applying bootstrapping to estimate the reliability of detected DTU events and shows good performance at all replication levels (median false positive fraction < 0.05). We compare RATs to two existing DTU tools, DRIM-Seq & SUPPA2, using two publicly available simulated RNA-seq datasets and a published human RNA-seq dataset, in which 248 genes have been previously identified as displaying significant DTU. RATs with default threshold values on the simulated Human data has a sensitivity of 0.55, a Matthews correlation coefficient of 0.71 and a false discovery rate (FDR) of 0.04, outperforming both other tools. Applying the same thresholds for SUPPA2 results in a higher sensitivity (0.61) but poorer FDR performance (0.33). RATs and DRIM-seq use different methods for measuring DTU effect-sizes complicating the comparison of results between these tools, however, for a likelihood-ratio threshold of 30, DRIM-Seq has similar FDR performance to RATs (0.06), but worse sensitivity (0.47). These differences persist for the simulated drosophila dataset. On the published human RNA-seq dataset the greatest agreement between the tools tested is 53%, observed between RATs and SUPPA2. The bootstrapping quality filter in RATs is responsible for removing the majority of DTU events called by SUPPA2 that are not reported by RATs. All methods, including the previously published qRT-PCR of three of the 248 detected DTU events, were found to be sensitive to annotation differences between Ensembl v60 and v87.

This study analyzed the chemical compositions, growth performance and nutrient efficiency of fish meal supplemented with varying percentage of S. indicum). A total of 150 of C. gariepinus fingerlings were grouped into 6 tanks with 20 C. gariepinus per tank. Each tank of fish was served with prepared fish meals supplemented with various levels of beniseed (S. indicum), namely, DT1 (commercial diet), stand as the control group, DT2 (0% beniseed with 100% soya bean meal, DT3 (25% beniseed with 75% soya bean meal, DT4 (50% beniseed with 50% soya bean, DT5 (75% beniseed with 25% soya bean and DT6 (100% beniseed with 0% soya bean, individually. Chemical compositions of each experimental diet and fish carcass were determined and the feed utilization by fishes was equally monitored and calculated. Higher levels of moisture content (7.42%), crude fiber (4.24%), total ash (3.16%), crude protein and fat (29.21 and 30.01%) and carbohydrate (27.21%) were established for the dietary group (DT6) as compared to other dietary groups. In contrast, the fish carcass moisture, crude fiber, and total ash contents were high in fish fed DT4 and DT2 compared to others. Elevated calcium (760.7 and 763.6 mg/100g), phosphorus (683.4 and 685.1 mg/100g), sodium (302.4 and 303.4 mg/100g), potassium (820.6 and 825 mg/100g) and iron (32.67 and 37.31 mg/100g) contents were noted in DT5 and DT6 than the other diets. The fish carcass fed DT6 were richer in calcium (803 mg/100g), phosphorus (5023 mg/100g), sodium (492 mg/100g), potassium (6313 mg/100g) and iron (5.12 mg/100g) than the others. C. gariepinus fed DT6 recorded high weight gains (45.64 mg) while fish DT4 had a value of length gain (1.80 cm). Higher significant values were observed for SGR (54.33%), PER (2.47%), FI (2.85%) and SR (80.23%) as feed utilization in fish fed DT6. However, experimental diets (DT5 and DT6) with 75 and 100% S. indicum inclusion look promising and would enhance adequate growth performance and nutrient utilization of C. gariepinus, which may be used for the development of the product in various food industries.

The functional properties of each diet and hematological indices of the treated fish were determined. All prepared diets have improved the functional properties and their phytotoxins level remains within the permissible limit as compared to control diets (DT1). The formulated diets have potentially influenced the hematological indices analyzed compared to the control diet (DT1). At any level of S. indicum inclusion in the fish meal of C. gariepinus there was a potential improvement of the functional properties, hematological parameters and maintaining the levels of phytotoxins not to rise above the permissible limit. Thus, experimental diets (DT5 and DT6) with 75 and 100% S. indicum would be promising candidates which may be used for the development of the product in various food industries.

Résumé :
The objectives and the core elements of the European Course Credit Transfer System (ECTS) are briefly described. ECTS is a tool to manage student mobility as it facilitates transparency, academic recognition, and commitment of the student and involved institutions. The impact on student mobility and teaching after implementation of ECTS at the Technical University of Denmark (DTU) is reported. The ratio of guest students attending advanced environmental engineering courses at DTU increased from 7 percent of class to almost 50 percent over a three-year period. The number of DTU students studying abroad was also affected by the implementation of ECTS in combination with DTU's additional internationalisation activities. In 1998 DTU achieved balance between the inflow and outflow of students.

Estima-se que 7 a 8 milhões de indivíduos estejam infectados pelo Trypanosoma cruzi, agente etiológico da doença de Chagas (DC) (W.H.O., 2014), em especial na América Latina, onde essa doença é endêmica (Schofield e Dias, 1999). Desde a descoberta da DC, em 1909 por Carlos Chagas, a heterogeneidade do parasito foi considerada um fator relacionado às diferentes formas clínicas da doença. A classificação dos subtipos do T. cruzi foi determinada conforme as características biológicas, parasitismo tecidual, morfologia, virulência e patogenicidade do parasito na infecção murina (Brener, 1973; Andrade, 1974). Sendo o T. cruzi foi agrupado em três fenótipos, denominados como Biodemas I, II e III (Andrade e Magalhães, 1997). De modo geral, o Biodema I, correspondente ao Zimodema Z2b, foi caracterizado por apresentar cepas predominantemente de forma fina e macrofagotrópica na fase inicial da infecção, com alta virulência com 100% de mortalidade em 12 dias, e pico de parasitemia e mortalidade entre o 7º e o 11º dia pós-infecção (d.p.i.). O Biodema II, correspondente ao Zimodema Z2, apresenta cepas de forma predominantemente larga, miotrópica, com tropismo pelo músculo cardíaco e taxa de multiplicação lenta, cujo pico de parasitemia ocorre de maneira irregular entre o 12º e o 20º d.p.i. Cepas pertencentes a este tipo de Biodema podem apresentar diferentes níveis de virulência. Já o Biodema III, correspondente ao Zimodema Z1, exibe cepas de forma predominantemente larga e miotrópica, com envolvimento de músculo esquelético, pico de parasitemia tardio entre o 25º e o 30º d.p.i. e baixa mortalidade aos 30 dias (Andrade e Magalhães, 1997). Posteriormente, o parasito foi agrupado em dois grupos principais denominados como T. cruzi I e T. cruzi II, que anteriormente se encaixavam na classificação como Biodema III (Zimodema Z1) e Biodema II (Zimodema Z2), respectivamente. As cepas híbridas e com caracterização incerta foram denominadas apenas como T. cruzi até a realização de novos estudos (Anonymous, 1999). Recentemente, as populações de T. cruzi foram reagrupadas, conforme a expressão fenotípica e as características moleculares, em unidade de tipagem (do inglês “Discrete Typing Units” - DTU), denominadas TcI, TcII, TcIII, TcIV, TcV e TcVI, as quais foram caracterizadas por marcadores genéticos (Zingales et al., 2009). Estudos geográficos e epidemiológicos apontam distribuições distintas dessas DTUs, sendo os TcI e TcII mais abrangentes, visto que o TcI é prevalente na América Central e na região norte do Brasil, e o TcII é encontrado predominantemente na América do Sul (Zingales et al., 2009). Essas distintas DTUs, aparentemente, apresentam diferentes padrões de tropismo e parasitismo tecidual (Vago et al., 2000). O padrão do parasitismo tecidual e o grau de resistência ao tratamento por sua vez tem relação com as propriedades biológicas do parasito, uma vez que de modo geral a infecção com o T. cruzi I e o T. cruzi II estão relacionadas com casos de cardiomiopatia chagásica crônica (CCC). Ainda, a DTU I foi considerada resistente frente ao único fármaco disponível comercialmente no Brasilpara o tratamento da DC, o Benznidazol (Bz). Por outro lado, o T. cruzi II foi considerado macrofagotrópico e parcialmente susceptível ao tratamento com Bz (Filardi e Brener, 1987; Toledo et al., 2003; Toledo et al., 2004). Em estudos clínicos randomizados, o tratamento com Bz na fase aguda favorece a redução da carga parasitária e sororeversão dos pacientes tratados (de Andrade et al., 1996; Coura et al., 1997; Sosa-Estani et al., 1998). Sugere-se que o tratamento etiológico com Bz deva ser iniciado nos estágios iniciais da DC, pois quando iniciado na fase aguda pode alcançar níveis de 70% de cura (Rodrigues Coura e de Castro, 2002). Outros trabalhos tem revelado que a intervenção com o tratamento de pacientes na forma indeterminada melhora o prognóstico da doença (Lana et al., 1992; Macchado-de-Assis et al., 2013). O Bz ativa a resposta imune inata com aumento dos níveis de monócitos, todavia com diminuição dos monócitos TNF-γ + e IL-12+ (Sathler-Avelar et al., 2009). Na resposta imune adaptativa, o tratamento com Bz favorece mecanismos imunomoduladores mediados por IL-10 produzido por linfócitos T CD4 e B, além de aumentar o número de células NK ativas no sangue periférico, que tem participação na produção e citocinas pró-inflamatórias e moduladoras (Sathler-Avelar et al., 2006). Isto demonstra a importância da inter-relação entre a resposta imune inata e adaptativa no controle da resposta imune exacerbada, que poderá acarretar na lesão tecidual (Sathler-Avelar et al., 2009). Por outro lado, os casos de falha terapêutica, aparentemente, dependem de mecanismos que interferem na expressão de genes relacionados à resistência de algumas cepas do parasito (Campos et al., 2014). Apesar de estar elucidado que o Bz alcança níveis de cura importantes nos pacientes tratados na fase aguda da DC, ainda se faz necessário compreender a participação das diferentes DTUs de T. cruzi na patogênese da doença, bem como elucidar as alterações imunológicas e histopatológicas cardíacas frente ao tratamento na infecção com cepas do T. cruzi que apresentam diferentes graus de susceptibilidade ao tratamento com Benznidazol. Portanto, neste trabalho avaliamos a infecção com duas cepas de DTUs distintas, a cepa Y, caracterizada como TcII e considerada parcialmente resistente ao tratamento com Bz no modelo murino e susceptível no modelo canino, e a cepa Colombiana, classificada como TcI e resistente à terapia com Bz nos modelos murino e canino (Filardi e Brener, 1987; Veloso et al., 2001; Guedes et al., 2002). _________________________________________________________________________________________________________________
ABSTRACT: Trypanosoma cruzi infection may be caused by different strains of distinct discrete typing units (DTUs), characterized by different biological and genetic patterns, which result in variable clinical forms of chronic Chagas disease. These biological differences of the parasite are apparently related to the distinct patterns of resistance to the Benznidazole treatment, the only drug available for Chagas disease treatment in Brazil. In randomized clinical trials, Benznidazole treatment presents a higher cure rate in the acute phase, with reduction of the parasite load and negative seroreversion of treated and cured patients, but there are still questions about the immunopathological changes resulting from this treatment. This study evaluates the immune response and cardiac lesions in dogs experimentally infected with different strains of distincts T. cruzi DTUs that showing different degrees of susceptibility to treatment with Benznidazole, namely Y and Colombian from TcI and TcII DTU, respectively. For this, mongrel dogs were experimentally infected with 2000 Y or Colombian T. cruzi trypomastigotes and undergoing Benznidazole treatment at oral dose of 7 mg/kg, divised in two by day, for 45 days. The infection with the Y strain led to increased levels of alanine aminotransferase and aspartate aminotransferase, leucopoenia, thrombopoenia, inversion of the ratio of CD4+/CD8+ T-lymphocytes and alterations in monocyte number. In addition, Y strain infection stimulated the production of IFN-γ by CD4+ and CD8+ T-lymphocytes and IL-4 by CD8+ T-cells. In the chronic phase, significant heart inflammation and fibrosis were observed. During infection with the Colombian strain, increased levels of alanine aminotransferase, erythrocytes, haematocrit and haemoglobin were observed. In addition, CD8+ T-lymphocytes isolated from the peripheral blood produced higher levels of IL-4. The latter results suggests that during the acute phase, infection with the Colombian strain may remain unnoticed by circulating mononuclear cells. In the chronic phase, a significant increase in the number of inflammatory cells was detected in the right atrium, demonstrating that strains of different DTUs interact differently with the host. When was evaluated the Benznidazole treatment of dogs infected with the Y strain it was observed increase levels of alanine aminotransferase, urea and hemoglobin, lymphopenia, neutropenia, monocytopenia and inversion of the ratio of CD4+/CD8+ T-lymphocytes. The infection with the Y strain and Benznidazole treatment stimulated the production of IFN-γ and IL-4 by CD4+ T-lymphocytes. In dogs infected with the Colombian strain and Benznidazole treatment, it was observed increase of alanine aminotransferase and hemoglobin, and decrease the monocyte number. So the treatment in Colombian infection controlled the increased amount of red blood cells. Moreover, in chronic phase, dogs with Y and with Colombian strains infection and Benznidazole treatment do not showed significant difference in the number of inflammatory cells and collagen area in the right atrium compared to the not infected and treated group. Therefore, the Benznidazole treatment despite having changed some cell populations in peripheral blood, had significant participation for decrease the IgG level and the inflammation and cardiac fibrosis. So, in this work, the Y strain was apparently first recognized by the immune system, while the Colombian strain escaped from the immune response in the acute phase of Chagas disease, which would impact the progression of cardiomyopathy in the chronic phase. Moreover, the Benznidazole treatment in acute experimental infection controlled the cardiac damage in chronic phase.

La enfermedad de Chagas, o tripanosomiasis americana, es una zoonosis producida por el parásito protozoario flagelado denominado Trypanosoma cruzi, su principal vector es un insecto hematófago de la subfamilia Triatominae, principalmente los géneros Rhodnius (R. prolixus), Triatoma (T. infestans), y Panstrongylus (P. megistus). De las 40 especies de triatominos reconocidos como vectores de la enfermedad, 28 especies se encuentran exclusivamente en México, y 8 son compartidos con los EE.UU. (Ibarra Cárdenas et al., 2009), además de contar con un gran número de reservorios domésticos y silvestres sinantrópicos, dentro de los cuales se encuentra las especies del género Didelphis, desempeñando un papel importante en la transmisión de la enfermedad en hábitats peridomésticos, debido a que pueden actuar simultáneamente como reservorios y vector de Trypanosoma y ser considerados junto con los armadillos y osos hormigueros, como los reservorios más antiguos del parasito. La determinación de la prevalencia de Trypanosoma cruzi en marsupiales de una región determinada, permite tener una aproximación del riesgo que corren otras especies de mamíferos de ser infectadas por este parásito en dicha región. Por otro lado, dado que el genotipo de los parásitos ha sido asociado a la presentación de variaciones en la virulencia y patogenicidad del parásito, la identificación de los linajes de T. cruzi en los marsupiales de la región en estudio, contribuye a conocer los riesgos de salud que corren las especies susceptibles de ser infectadas con las cepas parasitarias circulantes. Se determinó la prevalencia puntual de T. cruzi en las especies de marsupiales presentes en la reserva ecológica El Zapotal e identificar los linajes del parásito circulantes en estos animales. Se hizo un estudio estratificado dentro de la reserva ecológica “El Zapotal”, ubicada en la ciudad de Tuxtla Gutiérrez, Chiapas. Se muestrearon 60 marsupiales en un período comprendido de junio a septiembre del 2014. Para determinar la prevalencia se utilizó el gen miniexón para ampolificar una secuencia de 197 pb (ref). La identificacion de los linajes se realizó amplificndo un fragmento de 832pb del gen TcSC5D y se secuenció. El análisis de las secuencias se realizó con el Software Mega 6.06 mediante cálculos de distancia por el método Maximum Likelihood, con el algoritmo de Tamura de tres parámetros y máxima verosimilitud, con un bootstraping de 500 repeticiones. Para calcular la correlación entre dos matrices de proximidad, se generó una matriz de identidad/similitud utilizando el software MatGAT (Matrix Global Alignment Tool) v2.01 y se realizó un análisis de Mantel. La prevalencia puntual de infección por T. cruzi para el conjunto de los marsupiales presentes en El Zapotal, Tuxtla Gutiérrez en Chiapas, fue de 40%. La prevalencia fue mayor para Philander oposum (57.10%), seguido de Didelphis marsupialis (39.5%) y Didelphis virginiana (30%). Se determinó la presencia del Linaje TCl del Trypanosoma cruzi en l6 de los 60 marsupiales muestreados.

Résumé :
Estudos termoanalíticos de alguns aditivos alimentares da classe dos realçadores de sabor foram desenvolvidos visando avaliar sua estabilidade e resistência durante o preparo de alimentos a quente assim como investigar os eventuais intermediários de decomposição que poderiam resultar destes processos. Os sais foram obtidos de fontes industriais ou sintetizados e submetidos à caracterização por análise elementar, espectrometria vibracional na região do infra-vermelho, termogravimetria/termogravimetria derivada, análise térmica diferencial e em alguns casos, calorimetria exploratória diferencial. Foram estudados o ácido glutâmico e seus sais de amônio, lítio e sódio mono e dissubstituídos. Em todos os casos observou-se uma conversão a piroglutamato após desidratação dos sais monossubstituídos, a qual ocorre via a a-carboxila. A estabilidade térmica destes sais foi da ordem de 190-200 °C. No caso dos sais dissubstituídos de lítio e sódio não houve conversão ao piroglutamato pois as duas carboxilas estão salificadas. Os glutamatos de magnésio, cálcio estrôncio e bário, também foram preparados e investigados quanto ao seu comportamento térmico. Os sais se formaram na estequiometria 2:1 (ligante:metal), apresentando águas de hidratação em número característico e foram estáveis até 190- 200 °C. Finalmente foram estudados os mecanismos de decomposição térmica do inosinato-monofosfato de sódio e do guanilato-monofosfato de sódio, dois nucleotídeos que apresentam a propriedade de realçar o sabor de alimentos. Ambos apresentaram elevado grau de hidratação, para o qual foi possível distinguir mecanismos característicos de desidratação. A decomposição dos sais anidros ocorreu com saída do grupo purínico, seguida da decomposição do restante da molécula e formação de pirofosfato de sódio como resíduo final.
Thermal analytical studies of some food addictives of the flavor enhancer class were developed in order to evaluate their stability and resistance to the hot cooking process, as well as to identify the intermediaries of thermal decomposition that could remain at the end of such processes. The salts were obtained from industrial sources or synthesized and characterized by elemental analysis, infra-red spectroscopy, thermogravimetry/derivative thermogravimetry, differential thermal analysis and in some opportunities to differential scanning calorimetry. The glutamic acid and its ammonium, lithium and sodium salts mono and disubstituted were investigated. In all cases a conversion to pyroglutamate has been observed in the free acid and its monosubstituted salts after dehydration. The conversion undergoes by the ?-carboxyl group. The thermal stability was observed to be as high as 190-200 °C. In the case of the lithiu m and sodium dissubstituted salts any conversions to pyroglutamates were observed, once both carboxyl groups were salified. Magnesium, calcium, strontium and barium glutamates has also been synthesized and investigated in relation to its thermal behavior. The salts were formed in the 2:1 stoichiometry (ligand:metal), presenting hydration waters in a characteristic content and showed to be stable up to 190-200 °C. Finally the thermal decomposition mechanisms of dissodium inosinatemonophosphate and dissodium guanilate-monophosphate two nucleotides with flavor enhancement properties in food were also investigated. Both presented high degree of hydration, to which it was possible to propose a water release mechanism. The decomposition of the anhydrous salts occurred with release of the purine group followed by the decomposition of the rest of the molecule generating sodium pyrophosphate as residue.

Bioidentical hormones are defined as compounds that have exactly the same chemical and molecular structure as hormones that are produced in the human body. It is believed that the use of hormones may be safer and more effective than the non-bioidentical hormones, because binding to receptors in the organism would be similar to the endogenous hormone. Bioidentical estrogens have been used in menopausal women, as an alternative to traditional hormone replacement therapy. Thermal data of these hormones are scarce in literature. Thermal analysis comprises a group of techniques that allows evaluating the physical-chemistry properties of a drug, while the drug is subjected to a controlled temperature programming. The thermal techniques are used in pharmaceutical studies for characterization of drugs, purity determination, polymorphism identification, compatibility and evaluation of stability. This study aims to characterize the bioidentical hormones estradiol and estriol through thermal techniques TG/DTG, DTA, DSC, DSC-photovisual. By the TG curves analysis was possible to calculated kinetic parameters for the samples. The kinetic data showed that there is good correlation in the different models used. For both estradiol and estriol, was found zero order reaction, which enabled the construction of the vapor pressure curves. Data from DTA and DSC curves of melting point and purity are the same of literature, showed relation with DSC-photovisual results. The analysis DTA curves showed the fusion event had the best linearity for both hormones. In the evaluation of possible degradation products, the analysis of the infrared shows no degradation products in the solid state

Résumé :
O tipo de crescimento da haste da soja é característica diferenciadora de cultivares. Os genes, Dt1 e Dt2, afetam a terminação da haste, visto que os tipos de crescimento são classificados em determinado, semideterminado e indeterminado. O tipo de crescimento determinado predominou no Brasil até o início dos anos 2000, ao passo que, na contemporaneidade, há preferência pelo tipo de crescimento indeterminado, principalmente na região centro sul do Brasil. No entanto, a dificuldade de seleção e a tendência de se utilizar com maior frequência cultivares indeterminadas e semideterminadas, nos programas de melhoramento, têm provocado a caracterização fenotípica errônea dos genótipos. Nesse sentido, o presente trabalho teve como objetivos: (a) mapear e validar marcadores moleculares para classificar a soja quanto ao tipo de crescimento, buscando facilitar a descrição de cultivares e a seleção genotípica; (b) avaliar características agronômicas de progênies e suas linhas irmãs contrastantes para o gene Dt1 identificadas pelo fenótipo dos respectivos tipos de crescimento. Para mapeamento e validação dos marcadores moleculares, foram utilizadas duas populações F2:3: T 117 (tipo de crescimento semideterminado) x Igra RA 518 RR (tipo de crescimento indeterminado) e CD 235RR (tipo de crescimento determinado) x Igra RA 518 RR. O estudo evidenciou que a associação do marcador molecular ao gene GmTFL1b foi eficiente na classificação dos tipos de crescimento em soja. O marcador sat_064 está ligado ao gene Dt2, localizado no Grupo de Ligação G do mapa consenso da soja, com frequência de recombinação de 19,4%. Os marcadores moleculares para os genes Dt1 e Dt2 são eficientes na descrição de genótipos quanto ao tipo de crescimento da haste da soja bem como para serem utilizados na seleção em programa de melhoramento. Na avaliação das características de três progênies F4:6:9 de soja, cada uma com três linhas irmãs as quais contrastam para o gene Dt1, utilizando para diferenciação dos tipos de crescimento o fenótipo. Nas progênies avaliadas, não houve diferenças entre os tipos de crescimento indeterminado (Dt1Dt1) e determinado (dt1dt1) na massa de planta, diâmetro da haste e massa total de grãos. Quanto as linhas com tipo de crescimento semideterminado (Dt1dt1), apresentaram massa de planta, diâmetro da haste, número de vagens, número de ramos e massa total de grãos maiores que as linhas com tipo de crescimento indeterminado, e altura de plantas foram maiores que linhas com tipo de crescimento determinado. Além disso, comprimento do racemo da haste é maior nas plantas com tipo de crescimento determinado que em plantas com tipo de crescimento semideterminado. Entre as progênies avaliadas, as do tipo de crescimento determinado apresentam racemos apicais nos ramos nas plantas e as com tipos de crescimento semideterminado e indeterminado não apresentam racemos apicais nos ramos. Nessas linhagens avaliadas, havia um nível de homozigose de 98,4375%, a segregação foi basicamente para o gene Dt1 de modo a facilitar a classificação de tipos de crescimento.
The type of stem growth of soybean is a distinguishing feature of cultivars. The genes Dt1 and Dt2 affect termination of the stem, and the types of growth are classified in determinate, semi-determinate and indeterminate. The predominant type of determinate growth in Brazil until the early 2000's. Nowadays preference for type of indeterminate growth is mainly in the central southern Brazil. The difficulty of a precise indication for the growth type in cultivars of soybean is offently present in breeding programs. Phenotypic characterization is sometimes erroneously described. This study aimed to: (a) map and validate molecular markers to classify the type of soybean growth, seeking to facilitate the description of cultivars and genotypic selection, (b) evaluate agronomic characteristics and their sisters contrasting progeny lines for sisters Dt1 gene identified by the phenotype of the respective types of growth. For mapping and validation of molecular markers were used two populations F2:3: T 117 (semi-determinate growth type) x Igra RA 518 RR (sort of indeterminate growth) and CD 235RR (determinate growth type) x Igra RA 518 RR. The study revealed that the association of the molecular marker to the gene GmTFL1b was efficient in the classification of types of growth in soybean. The marker sat_064 was connected to Dt2 gene which is located in the Liaison Group G of the consensus map of soybeans with recombination frequency of 19.4%.The Molecular markers for genes dt1 and dt2 were efficient in describing the genotypes for of soybean stem growth, as well as, for use in selection of a breeding program. The characteristics of three soybean progeny F4:6:9, each one with three sisters contrasting lines for gene Dt1, using for differentiation of phenotype growth type have been evaluated. Results indicated that there were no differences between indeterminate (Dt1Dt1) and determinate (dt1dt1) growth types when the mass of plant, stem diameter and total mass of grains. On the other side, semi-determinate growth type lines (Dt1dt1) has shown mass of plant, stem diameter, number of pods, number of branches and the total mass of grains larger than of indeterminate soybean growing type. The height of plants were greater on plants of semi determinate growth type. The length of the stem raceme was greater on determinate than plants of semi determinate growth type. The three evaluated progenies exhibited apical racemes on the branches of determinate with semi-determinate. Indeterminate growth types did not show apical racemes in the branches. These strains reached a level of homozygosis of 98.4375%. Segregation was basically for gene Dt1 which facilitated the classification in soybean of different growth type.

Since its synthesis over 48 years rifampicin has been extensively studied. The literature reports the characterization of thermal events for rifampicin in nitrogen atmosphere, however, no characterization in synthetic air atmosphere. This paper aims to contribute to the thermal study of rifampicin through thermal (TG / DTG, DTA, DSC and DSC - FOTOVISUAL ) and non-thermal (HPLC, XRPD , IR - FTIR , PCA) and its main degradation products ( rifampicin quinone , rifampicin N-oxide 3- formylrifamicin). Rifampicin study was characterized as polymorph form II from techniques DSC, IR and XRPD. TG curves for rifampicin in synthetic air atmosphere showed higher thermal stability than those in N2, when analyzed Ti and Ea. There was characterized as overlapping events melting and recrystallization under N2 with weight loss in the TG curve, suggesting concomitant decomposition. Images DSCFotovisual showed no fusion event and showed darkening of the sample during analysis. The DTA curve in synthetic air atmosphere was visually different from DTA and DSC curves under N2, suggesting the absence of recrystallization and melting or presence only decomposition. The IV - FTIR analysis along with PCA analysis and HPLC and thermal data suggest that rifampicin for their fusion is concomitant decomposition of the sample in N2 and fusion events and recrystallization do not occur in synthetic air atmosphere. Decomposition products studied in an air atmosphere showed no melting event and presented simultaneously to the decomposition initiation of heating after process loss of water and / or solvent, varying the Ti initiating events. The Coats - Redfern , Madsudhanan , Van Krevelen and Herwitz - Mertzger kinetic parameters for samples , through the methods of OZAWA , in an atmosphere of synthetic air and / or N2 rifampicin proved more stable than its degradation products . The kinetic data showed good correlation between the different models employed. In this way we contribute to obtaining information that may assist studies of pharmaceutical compatibility and stability of substances

Résumé :
Die verformungsinduzierten Phasenumwandlungen und die Zwillingsbildung wurden in drei metastabilen austenitischen Cr-Mn-Ni-Stählen mit unterschiedlichem Nickelgehalt im breiten Temperaturbereich untersucht. Die entwickelten STU- und DTU-Diagramme fassen die gewonnenen Erkenntnisse zusammen und charakterisieren die verformungsinduzierten Gefügeänderungsprozesse in Abhängigkeit von der Spannung und der Temperatur. Die thermodynamischen Berechnungen bestätigen die Unterschiede in der chemischen Triebkraft für die Martensitumwandlung zwischen den Stählen und erklären unterschiedliches Werkstoffverhalten. Ein thermodynamisch-mechanisches Modell der verformungsinduzierten α‘-Martensitbildung wurde entwickelt. Der maximale α‘-Martensitanteil wird als Funktion der Gesamttriebkraft und der Temperatur mit einer guten Genauigkeit beschrieben. Des Weiteren wurde ein Modell der Umwandlungsplastizität mit Berücksichtigung der Plastizitätsverringerung infolge der isothermen oder spannungsinduzierten Martensitbildung entwickelt. Außerdem wurde der Einfluss von Mikroseigerungen auf die verformungsinduzierte Martensitbildung anhand drei Modellstähle untersucht und bestätigt.

Résumé :
The Kikeh field, owned by Murphy and Petronas Carigali was the first time to use a Spar platform outside of the Gulf of Mexico and also the first time to use a semi-submersible Tender Assist Drilling Unit (TADU) for drilling along a Spar. This paper presents the design and installation aspects of the lashing system of the TADU and the Dry Tree Unit (DTU) Spar for the Kikeh project. The utilization of the TADU in the Kikeh field significantly reduces the weight and cost of the topsides of the Spar and increases the drilling efficiency. In the mean time it has posed a challenging job for the engineers to design the lashing system for the two floaters. This paper will discuss the TADU/DTU concept and benefits along with TADU lashing system design philosophy, design criteria and environment. Different phases of the design process will be discussed in detail, including concept selection, numerical analysis and model test. Several design concepts including the selected design and other alternatives will be explored with pros and cons of each concept explained. Characteristics of the two body motions and lashing tensions will be demonstrated. The selection of the nylon rope and hardware for the lashing system will be discussed. Analysis methodology and modeling of the TADU/DTU lashing system will be discussed. Model test results will be compared with the analytical predictions. Due to the complex nature of the systems and limitation of the analytical tools, model test served as an important tool in the design process. We will show how the results influenced the design of the gangway between the TADU and the DTU. The installation procedures of the TADU mooring and lashing systems will also be presented.

Résumé :
Hvad karakteriserer elevers skriveudvikling i indskolingen, fra de eksperimenterer med bogstaver og begynder at lære at udtrykke sig og kommunikere på skrift, til de skriver korte sammenhængende tekster? Det har været et centralt spørgsmål for os i projektet Teaching platform for developing and automatically tracking early stage literacy skills (ATEL, 2018-2023). Projektet er tværinstitutionelt og er blevet gennemført af forskere fra DPU, Aarhus Universitet, Nationalt Videncenter for Læsning og DTU i samarbejde med WriteReader, der har udviklet app’en Skriv og læs. I projektet har vi også samarbejdet med alle skoler i Svendborg Kommune samt enkelte skoler i Odense Kommune.

Résumé :
Zerbitizazio kontzeptuak manufaktura-enpresek beren negozioak ekoiztutako ondasunetan ez ezik, zerbitzuetan ere oinarritzeko duten joerari egiten dio erreferentzia. Horrek esan nahi du balio proposamenen zorroak handitu eta soluzio oso gisa integratu eta lotu behar direla. Era berean, zerbitzuak emateagatik edota produktuengatik zerbitzuak balira bezala kobratzeagatik diru-sarrerak sortzea dakar. Azterlan honek zerbitizazioaren fenomenoa kontzeptualizatzen du, Kataluniako industriaren egoera aurkezten du (ikuspegi mesoekonomikoa) eta Kataluniako 8 enpresaren esperientziak biltzen ditu (ikuspegi mikroekonomikoa) zerbitizazioaren oztopoak eta onurak aztertzeko.

Résumé :
experimental methods for quantifying effects of water content and other dynamic environmental factors on bacterial growth in partially-saturated soils. Towards this end we reviewed critically the relevant scientific literature and performed theoretical and experimental studies of bacterial growth and activity in modeled, idealized and real unsaturated soils. The natural wetting-drying cycles common to agricultural soils affect water content and liquid organization resulting in fragmentation of aquatic habitats and limit hydraulic connections. Consequently, substrate diffusion pathways to soil microbial communities become limiting and reduce nutrient fluxes, microbial growth, and mobility. Key elements that govern the extent and manifestation of such ubiquitous interactions include characteristics of diffusion pathways and pore space, the timing, duration, and extent of environmental perturbations, the nature of microbiological adjustments (short-term and longterm), and spatial distribution and properties of EPS clusters (microcolonies). Of these key elements we have chosen to focus on a manageable subset namely on modeling microbial growth and coexistence on simple rough surfaces, and experiments on bacterial growth in variably saturated sand samples and columns. Our extensive review paper providing a definitive “snap-shot” of present scientific understanding of microbial behavior in unsaturated soils revealed a lack of modeling tools that are essential for enhanced predictability of microbial processes in soils. We therefore embarked on two pronged approach of development of simple microbial growth models based on diffusion-reaction principles to incorporate key controls for microbial activity in soils such as diffusion coefficients and temporal variations in soil water content (and related substrate diffusion rates), and development of new methodologies in support of experiments on microbial growth in simple and observable porous media under controlled water status conditions. Experimental efforts led to a series of microbial growth experiments in granular media under variable saturation and ambient conditions, and introduction of atomic force microscopy (AFM) and confocal scanning laser microscopy (CSLM) to study cell size, morphology and multi-cell arrangement at a high resolution from growth experiments in various porous media. The modeling efforts elucidated important links between unsaturated conditions and microbial coexistence which is believed to support the unparallel diversity found in soils. We examined the role of spatial and temporal variation in hydration conditions (such as exist in agricultural soils) on local growth rates and on interactions between two competing microbial species. Interestingly, the complexity of soil spaces and aquatic niches are necessary for supporting a rich microbial diversity and the wide array of microbial functions in unsaturated soils. This project supported collaboration between soil physicists and soil microbiologist that is absolutely essential for making progress in both disciplines. It provided a few basic tools (models, parameterization) for guiding future experiments and for gathering key information necessary for prediction of biological processes in agricultural soils. The project sparked a series of ongoing studies (at DTU and EPFL and in the ARO) into effects of soil hydration dynamics on microbial survival strategy under short term and prolonged desiccation (important for general scientific and agricultural applications).
