Abstract:
AbstractThe role of transanal total mesorectal excision (taTME) in minimally invasive proctectomy, especially rectal cancer surgery, is increasing. There has been exponential growth in uptake from the initial in vivo case in 2010 to the present day. Early adopters of taTME are well within the mature portions of their learning curve, but there are a significant number of novice taTME surgeons. We have overviewed the critical aspects of patient selection, operating room set-up, and necessary equipment. In particular, we recommend that a one-team approach is used for the early cases, and ideally with an experienced proctor. The important technical pearls that will aid the novice taTME surgeon were also described.

Abstract:
Many cells exploit the bending or rotation of flagellar filaments in order to self-propel in viscous fluids. Often swimming occurs in complex, nonlinear fluids, e.g. mucus. Futhermore even in simple Newtonian fluids, if swimming appendages are deformable then locomotion is subject to fluid-structure interactions. The fundamental question addressed in this thesis is how exactly locomotion is impacted, in particular if it is faster or slower, with or without these effects. First we study locomotion in shear-thinning and viscoelastic fluids with rigid swimming appendages. Following the introductory Chapter, in Chapter 2 we propose empirical extensions of the classical Newtonian resistive-force theory to model the waving of slender filaments in non-Newtonian fluids, based on experimental measurements for the motion of rigid rods in non-Newtonian fluids and on the Carreau fluid model. We then use our models to address waving locomotion in shear-thinning fluids, and show that the resulting swimming speeds are systematically lowered a result which we are able to capture asymptotically and to interpret physically. In Chapter 3 we consider swimming using small-amplitude periodic waves in a viscoelastic fluid described by the Oldroyd-B constitutive relationship. Using Taylor’s swimming sheet model, we show that if all travelling waves move in the same direction, the locomotion speed of the organism is systematically decreased. However, if we allow waves to travel in two opposite directions, we show that this can lead to enhancement of the swimming speed, which is physically interpreted as due to asymmetric viscoelastic damping of waves with different frequencies. A change of the swimming direction is also possible. Secondly we consider the affect of fluid-structure interactions. In Chapter 4, we use Taylor’s swimming sheet model to describe an active swimmer immersed in an Oldroyd-B fluid. We solve for the shape of an active swimmer as a balance between the external fluid stresses, the internal driving moments, and the passive elastic resistance. We show that this dynamic balance leads to a generic transition from hindered rigid swimming to enhanced flexible locomotion. The results are physically interpreted as due to a viscoelastic suction increasing the swimming amplitude in a non-Newtonian fluid and overcoming viscoelastic damping. In Chapter 5 we consider peritrichously flagellated bacteria, such as Escherichia coli. The rotation of each motor is transmitted to a flexible rod called the hook which in turns transmits it to a helical filament, leading to swimming. The motors are randomly distributed over the body of the organism, and thus one expects the propulsive forces from the filament to almost cancel out leading to negligible swimming. We show that the transition to swimming is an elasto-hydrodynamic instability arising when the flexibility of the hook is below a critical threshold.

Nowadays, a considerable part of usability evaluations carried out during the software development lifecycle is conducted at later stages. Some of these assessments depend on the creation of fully functional prototypes, so they can be applied, and they re commonly performed after the development and deployment of software. This factor contributes significantly to the increase in cost of production. In this sense, from the research of prototyping, usability engineering and the conduction of a systematic review, this work presents an approach that allows the usability evaluation anticipation, through the use of mixed-fidelity prototypes created via the use of a computational tool. This tool assists in the creation and simulation of prototype interfaces, and enables collecting the following metrics of usability, for further analysis: task success, giving up on tasks, time on task, effort, screen balance, screen symmetry, screen balance, sequencing, order and complexity and system usability scale. In addition to the metrics that are collected by the tool automatically, other metrics are proposed to be collected from the observation of users using the prototypes created: partial success of the task, number of errors, help and documentation, time help, anger or frustration. The analysis of the obtained metrics point to areas of the system with potential usability problems. Moreover, the execution of new tests using the interfaces refined with the approach aid allow us to quantify the improvements resulting of the layout changes. In addition to the approach, the work presents its use in an experiment conducted with users. This experiment showed that, although not ali the metrics that can be collected from prototypes contribute to the refinement of interfaces, it was still possible to reduce the number of usability problems by just analyzing the results of the metrics.
Hoje em dia, uma consider?vel parte das avalia??es de usabilidade realizadas nos ciclos de desenvolvimento de software ? conduzida em etapas mais avan?adas nestes ciclos. Algumas destas avalia??es dependem ainda que prot?tipos totalmente funcionais sejam constru?dos, para que possam ser aplicadas, sendo comumente realizadas ap?s o desenvolvimento e implanta??o do software. Este fator contribui significativamente para o aumento no custo de produ??o. Neste sentido, a partir de pesquisas sobre prototipa??o e engenharia de usabilidade e da condu??o de uma revis?o sistem?tica sobre m?tricas para avalia??o de usabilidade, o presente trabalho apresenta uma abordagem que permite que a avalia??o de usabilidade seja antecipada, efetuando-a por meio da utiliza??o de prot?tipos de fidelidade mista - elaborados mediante o uso de uma ferramenta computacional. Esta ferramenta auxilia na cria??o e simula??o de prot?tipos de interfaces, al?m de permitir coletar as seguintes m?tricas de usabilidade, para posterior an?lise: sucesso de tarefas, desist?ncia de tarefas, tempo na tarefa, esfor?o, equil?brio de tela, simetria de tela, balan?o de tela, seq?enciamento, ordem e complexidade e escala de usabilidade do sistema. Al?m das m?tricas que s?o coletadas pela ferramenta, de forma autom?tica, s?o propostas as seguintes m?tricas, a serem coletadas a partir da observa??o dos usu?rios utilizando os prot?tipos criados: sucesso parcial de tarefa, n?mero de erros, auxilio e documenta??o, tempo de ajuda e raiva ou frustra??o. A an?lise das m?tricas obtidas permite apontar ?reas do sistema com poss?veis problemas de usabilidade. Al?m disto, a execu??o de novos testes utilizando as interfaces refinadas com o aux?lio da abordagem permite quantificar as melhorias realizadas pelas mudan?as de layout efetuadas. Al?m da abordagem, o trabalho apresenta seu uso em um experimento realizado com usu?rios. Este experimento permitiu verificar que, apesar de nem todas as m?tricas pass?veis de serem coletadas de prot?tipos contribu?rem para o refino das interfaces, ainda assim foi poss?vel reduzir o n?mero de problemas de usabilidade.

Objective: To evaluate CT phenotypes, airflow limitation and exacerbation-like episodes in heavy smokers. Methods: This cross-sectional study enrolled 172 smokers, with > 30 pack-years exposure, who underwent pulmonary function tests (PFTs) and quantitative computed tomography (QCT). Subjects were classified by presence or absence of airflow limitation according to the current GOLD criteria of post-bronchodilator FEV1/FVC < 0,7. QCT analysis of data in Airway Inspector software resulted in the establishment of two disease-predominant phenotypes groups: emphysema-predominant (EP) (>6 % of pixels < -950 HU) and non-emphysema-predominant (NEP) (<6 % of pixels < -950 HU). Results: The overall mean age was 63.39 ? 6.04 years, 58% were men, mean packyears smoking history was 70.7 ? 34.32 and mean body mass index (BMI) was 26.96 (?5.69). Most of the 58% of male subjects were distributed in the airflow limitation group, which had also a higher mean pack-years smoking history (77.20 ? 38.03 vs. 60.53 ? 24.50, p=0.009) and mean emphysema index (17.01 ? 9.96 vs. 4.52 ? 3.55, p<0.001), than the group without airflow limitation. About 8.9% of those subjects with no airflow limitation had exacerbation-like episodes, and 23,8% show emphysemapredominant phenotype. According to QTC analysis, the EP group exhibited worse FEV1/FVC mean ratio (55.62 ? 13.3) compared to the NEP (79.10 ? 9.78), p<0.001. Conclusions: Despite of no persistent airflow limitation, 8,9% of the heavy smokers had exacerbation-like episodes and QCT findings of emphysema. Those in the EP phenotype group, had worse PFTs values, higher smoking history, male predominance and also experienced more exacerbation-like episodes than NEP.
Objetivo: avaliar fumantes com alta carga tab?gica, analisando padr?es espirom?tricos, fenot?picos tomogr?ficos e desfechos cl?nicos. Material e M?todo: Foi realizado um estudo transversal com 172 fumantes de um protocolo de rastreamento para detec??o de c?ncer de pulm?o, com carga tab?gica acima de 30 anos-ma?o, que realizaram pelo menos uma tomografia computadorizada e uma espirometria dentro de um intervalo de um ano. Inicialmente os pacientes foram separados em dois grupos, com fun??o pulmonar normal (FPN) e fun??o pulmonar alterada (FPA), e posteriormente fez-se uma suban?lise de acordo com o fen?tipo tomogr?fico. Resultados: encontrou-se idade m?dia de 63,39 ? 6,04 anos, a maioria eram homens (58%) e a carga tab?gica m?dia foi 70,7 ? 34,32 anos-ma?o. Os pacientes com FPA experimentaram mais infec??es respirat?rias no ano anterior do que os indiv?duos com FPN, respectivamente (n = 29 e n = 5; p = 0,05). Os participantes do grupo com FPN eram mais jovens e com maior propor??o de mulheres que o grupo com FPA, respectivamente (61,48 ? 5,32 anos; 64,61 ? 6,17 anos; p <0,001; n = 39 (58%), n = 33 (31%); p <0,001). A carga tab?gica dos indiv?duos com FPN era inferior em rela??o ao grupo com FPA, respectivamente (60,53 ? 24,50 anos-ma?o e 77,20 ? 38,03 anos-ma?o; p<0.009). Cerca de 9% dos indiv?duos com fun??o pulmonar normal apresentaram epis?dios infecciosos no trato respirat?rio e quase um quarto dos participantes com FPN, 23,8%, tinham fen?tipo enfisematoso na an?lise tomogr?fica. O grupo com fen?tipo tomogr?fico enfisema-predominante (EP) apresentou os piores resultados de fun??o pulmonar em compara??o com o grupo de fen?tipo n?o-enfisematoso (NEP). Conclus?o: Neste estudo mesmo os fumantes com FPN apresentaram achados tomogr?ficos compat?veis com enfisema, assim como desenvolveram epis?dios de infec??o no trato respirat?rio similares a exacerba??o do DPOC. O fen?tipo EP teve os piores ?ndices de fun??o pulmonar e maior n?mero de epis?dios infecciosos no trato respirat?rio nos ?ltimos 12 meses.

The nanometric powders have special features that usually result in new properties, originating applications or expanding them in various fields of knowledge. Because having a high area/volume ratio, phenomena such as superficial strength of adsorption becomes greater than the weight of the powder which makes more difficult its handling. The high power of agglomeration of these powders requires study and development of equipments to enable its management into the plasma torch. The objective of this work is to develop a powder feeder which can solve the mainly problems about insertion of powder into the thermal spray developed in the laboratory of plasmas, which are carried out with plasma torch arc not transferred (plasma spray). Therefore, it was made a aluminum s powder feeder and tests were performed to verify their operation and determine its rate of deposition by spraying powders of niobium pentoxide (Nb2O5) and titanium dioxide (TiO2) with particle sizes less than 250 mesh (<0.063 mm). We used masses of 0.5 g - 1.0 g and 1.5 g of each powder in tests lasting 15 seconds - 20 to 25 seconds for each mass. The tests were performed in two ways: at atmospheric pressure using argon gas with a flow of 9 l / min as carrier gas and through a Venturi pipe also using argon gas with a flow of 9 l / min as carrier gas and with a flow of 20 l/min as the feed gas passing through the Venturi pipe. The powder feeder developed in this paper is very easy to be handling and building, resulting in feeding rate of 0.25 cm3/min - 1.37 cm3/min. The TiO2 showed higher feeding rates than the Nb2O5 in all tests, and the best rates were obtained with tests using mass 1.5 g and time of 15 seconds, reaching feeding rate of 1.37 cm3/min. The flow of feed had low interference in feeding rate during the tests
Os p?s nanom?tricos apresentam caracter?sticas especiais que geralmente resultam em novas propriedades, ampliando ou originando melhores aplica??es nas diversas ?reas de conhecimento. Devido ao fato de possuir uma alta raz?o ?rea/volume, fen?menos como a for?a de adsor??o de superf?cie tornam-se superiores ao peso, dificultando o seu manuseio. O alto poder de aglomera??o dificulta processos como o de alimenta??o de p?s em tochas de plasma, por exemplo. O objetivo do presente trabalho ? desenvolver um alimentador de p?s, para trabalhos com aspers?o t?rmica, que s?o realizados em tocha de plasma de arco n?o transferido (plasma spray). Para tanto, foi confeccionado um dispositivo em alum?nio, sendo realizados testes para verificar seu funcionamento e determinar sua taxa de alimenta??o durante aspers?o de p?s de pent?xido de ni?bio (Nb2O5) e di?xido de tit?nio (TiO2), com tamanhos de part?culas inferiores a mesh 250 (< 0,063 mm). Foram utilizadas massas de 0,5 g - 1,0 g e 1,5g de cada p?, em testes com dura??o de 15 s - 20 s e 25 segundos para cada massa. Os ensaios foram realizados de duas maneiras: ? press?o atmosf?rica utilizando-se g?s arg?nio com fluxo de 9 l/min como g?s de arraste e atrav?s de um tubo de Venturi utilizando tamb?m o g?s arg?nio com fluxo de 9 l/min como g?s de arraste e com fluxo de 20 l/min como g?s de alimenta??o, passando pelo interior do tubo de Venturi. O alimentador de p? desenvolvido neste trabalho ? de f?cil constru??o e manuseio, obtendo-se taxas de alimenta??o de 0,25 cm3/min - 1,37 cm3/min. O TiO2 apresentou maiores taxas de alimenta??o que o Nb2O5 em todos os testes, e as melhores taxas foram obtidas com os ensaios utilizando massa de 1,5 g e tempo de 15 segundos, atingindo taxa de alimenta??o de 1,37 cm3/min. O fluxo de alimenta??o apresentou pouca interfer?ncia na taxa de alimenta??o durante a realiza??o dos testes

Abstract:
O estudo dos mecanismos de fadiga por contato tem grande relevância para o estudo dos componentes mecânicos que estão sujeitos ao desgaste. O desgaste é um tipo de falha que ocorre na maioria dos componentes que trabalham em contato. Atualmente para prever o desgaste são utilizados métodos experimentais que permitem ajustar curvas semi-empíricas, ou seja, o resultado depende de vários testes que além de caros são demorados. Com o aumento da competitividade na indústria, o tempo se tornou artigo de luxo e com isso o aprimoramento dos modelos de cálculo e das simulações numéricas são muito bem justificados. O estudo aprofundado do mecanismo de fratura por contato sem dúvida pode dar subsídios para um melhor projeto do componente mecânico e assim conseguir predizer com maior precisão quando a falha por desgaste ocorrerá e assim evitar falhas catastróficas e paradas de máquinas não programadas gerando grandes prejuízos e também risco de vidas humanas Este estudo apresenta um modelo numérico utilizando o método dos elementos finitos computacional para a simulação do spalling em componentes mecânicos sujeitos à fadiga de contato. O modelo foi simplificado para duas dimensões e foi considerado estado plano de deformações. Este estudo apresenta uma aproximação na aplicação dos conceitos da Mecânica da Fratura para estimar a vida de componentes mecânicos. O resultado do modelo numérico é confrontado qualitativamente com resultados práticos. A geometria dos pits assim como as relações entre o Fator de intensidade de tensões e o tamanho da trinca é apresentado.

Las nuevas herramientas biotecnológicas ofrecen una amplia gama de posibilidades de desarrollo en todas las áreas donde el hombre se desenvuelve. La agricultura no esta ajena a esta posibilidad. El trigo de pan ( Triticum aestivum L), uno de los alimentos más importantes del mundo, puede beneficiarse significativamente al incorporar el uso de esta nueva tecnología dentro del proceso de creación de nuevas variedades. Los microsatélites o SSR (Simple Sequence Repeats), marcadores genéticos hipervariables, han demostrado ser una de las mejores alternativas para este cultivo. Por este motivo fueron los seleccionados para llevar a cabo el objetivo de la presente investigación, en la cual se busco asociar microsatélites a loci genéticos de proteínas de reserva y de dureza del grano, factores determinantes de la calidad panadera de este cereal. Para llevar a cabo está investigación se seleccionaron 80 genotipos de trigo de pan, a los cuales se les determinó: porcentaje de proteína del grano, volumen de sedimentación, gluten seco, gluten húmedo, gluten índex e índice de dureza. Esta información fue utilizada como base para seleccionar aquellos marcadores genéticos que estuvieran asociados con estos parámetros de calidad. De los seis microsatélites analizados cuatro estuvieron asociados con diferentes pruebas de calidad. El marcador Xglu A3 presentó correlaciones significativas con volumen de sedimentación (0,385), gluten seco (0,394) y gluten índex (0,377). Xgwm 164 se asoció significativamente con sedimentación (0,235) y gluten índex (0,233), el partidor Xgwm 135 presento correlaciones significativas con gluten seco (0,172) y gluten índex (0,221) y el SSR Xgdm 19 fue el marcador con mayor número de pruebas asociadas: porcentaje de proteínas (0,447), sedimentación (0,408), gluten seco (0,487), gluten índex (0,391) e índice de dureza (0,483). De estos cuatro microsatélites, Xglu A3 y Xgdm 19, son los más informativos con índices de polimorfismos (PIC) de 0,721 y 0,758 respectivamente. Ninguno de los SSR estudiados presentó asociación con gluten húmedo. Los marcadores Xgwm 498 y Xgdm 98, no se correlacionaron con ninguno de los parámetros de calidad. Al analizar la distribución de las frecuencia genotipica de los marcadores seleccionados, en los grupos de genotipos de buena, regular y mala calidad panadera, se seleccionó haplotipos promisorios para buena calidad. A todo el germoplasma analizado se le determinó la presencia de secalina, proteína de centeno, la cual existe en algunas líneas de trigo por efecto de translocaciones cromosomales con este cereal. Treinta y tres genotipos dieron positivo para este análisis. La mayoría de este grupo presentó bajos niveles de volumen de sedimentación. Este resultado indica la necesidad de tener presente este factor cuando se están determinando criterios de selección para calidad panadera. Paralelamente, en esta investigación se caracterizó las gluteninas de alto peso molecular, de las 80 líneas y variedades en ensayo. Las subunidades permitieron determinar el índice GLU-1, el que demostró ser un buen indicador de calidad panadera, por su buena asociación con volumen de sedimentación.

Neste trabalho investigamos o espectro de polariton de plasmons (modos de volume e superf?cie) assim como o espectro ?ptico (reflect?ncia e transmit?ncia) em uma estrutura quasi-peri?dica, que obedece uma sequ?ncia de Cantor. O sistema quasi-peri?dico de multi-camadas de Cantor ? criado quando duas camadas diferentes, de materiais distintos A e B, s?o dispostos de acordo com a seguinte rela??o de recorr?ncia: C1 = ABA;C2= C1B2C1;...;Cn= Cn-1BnCn-1 Onde Bn ? o mesmo meio da camada B mas com diferente espessura. O aparatus experimental mais simples para medir estes espectros, consiste em posicionar a super-rede tipo Cantor na forma de um filme embebido no v?cuo. Usando o m?todo da matriz-transfer?ncia, para simplificar a ?lgebra, ? poss?vel determinar-se a rela??o de dispers?o dos polaritons (modos de superf?cie e volume), assim como as express?es te?ricas de reflect?ncia e transmit?ncia. H? uma s?rie de resultados interessantes nestes espectros, os quais discutiremos em detalhes neste trabalho

Abstract:
Over the last decade, many researchers have conducted randomised trials alongside economic models. The work of these researchers has shown that both approaches are strengthened by their combined use and the conclusions they lead to are full of policy implications. In the latest CEDIL Methods Brief, Edoardo Masset, Research Director, CEDIL Programme, uses three examples to offer tips on the application of modelling to evaluate development interventions and explore various policy questions. The brief shows that models and experiments should be seen as complementary, rather than as alternative approaches. This brief is based on the CEDIL Inception Paper No. 9, Structural Modelling in Policy Making, by Orazio Attanasio and Debbie Blair. This paper is available on the CEDIL website.

Full text
Abstract:
The project objective was to more fully understand how the motion of pollen grains may be controlled by electrostatic forces, and to develop a reliable mechanized pollination system based upon sound electrostatic and aerodynamic principles. Theoretical and experimental analyses and computer simulation methods which investigated electrostatic aspects of natural pollen transfer by insects found that: a) actively flying honeybees accumulate ~ 23 pC average charge (93 pC max.) which elevates their bodies to ~ 47 V likely by triboelectrification, inducing ~ 10 fC of opposite charge onto nearby pollen grains, and overcoming their typically 0.3-3.9 nN detachment force resulting in non-contact electrostatic pollen transfer across a 5 mm or greater air gap from anther-to-bee, thus providing a theoretical basis for earlier experimental observations and "buzz pollination" events; b) charge-relaxation characteristics measured for flower structural components (viz., 3 ns and 25 ns time constants, respectively, for the stigma-style vs. waxy petal surfaces) ensure them to be electrically appropriate targets for electrodeposition of charged pollen grains but not differing sufficiently to facilitate electrodynamic focusing onto the stigma; c) conventional electrostatic focusing beneficially concentrates pollen-deposition electric fields onto the pistill tip by 3-fold as compared to that onto underlying flower structures; and d) pollen viability is adequately maintained following exposure to particulate charging/management fields exceeding 2 MV/m. Laboratory- and field-scale processes/prototype machines for electrostatic application of pollen were successfully developed to dispense pollen in both a dry-powder phase and in a liquid-carried phase utilizing corona, triboelectric, and induction particulate-charging methods; pollen-charge levels attained (~ 1-10 mC/kg) provide pollen-deposition forces 10-, 77-, and 100-fold greater than gravity, respectively, for such charged pollen grains subjected to a 1 kV/cm electric field. Lab and field evaluations have documented charged vs. ukncharged pollen deposition to be significantly (a = 0.01-0.05) increased by 3.9-5.6 times. Orchard trials showed initial fruit set on branches individually treated with electrostatically applied pollen to typically increase up to ~ 2-fold vs. uncharged pollen applications; however, whole-tree applications have not significantly shown similar levels of benefit and corrective measures continue. Project results thus contribute important basic knowledge and applied electrostatics technology which will provide agriculture with alternative/supplemental mechanized pollination systems as tranditional pollen-transfer vectors are further endangered by natural and man-fade factors.

Davidson, Irit, Hsing-Jien Kung, and Richard L. Witter. Molecular Interactions between Herpes and Retroviruses in Dually Infected Chickens and Turkeys. United States Department of Agriculture, January 2002. http://dx.doi.org/10.32747/2002.7575275.bard.

Full text
Abstract:
Tumors in commercial poultry are caused mainly by infection with avian herpes and retroviruses, the herpesvirus Marek's disease virus (MDV) and the retroviruses, reticuloendotheliosis (REV), lymphoid leukosis, subgroups A-I and J (ALV and ALV-J) in chickens, or Iymphoprolipherative disease (LPDV) in turkeys. Infection with one virus aggravates the clinical outcome of birds that are already infected by another oncogenic virus. As these viruses do not interfere for infection, MDV and one or more retroviruses can infect the same flock, the same bird and the same cell. While infecting the same cell, herpes and retroviruses might interact in at least three ways: a) Integration of retrovirus genomes, or genomic fragments (mainly the LTR) into MDV;b) alteration of LTR-driven expression of retroviral genes by MDV immediate- early genes, and c) by herpesvirus induced cellular transcriptional factors. The first type of molecular interaction have been demonstrated to happen efficiently in vitro by Dr. Kung, in cases multiple infection of cell cultures with MDV and REV or MDV and ALV. Moreover, Dr. Witter showed that an in vitro-created recombinant, RM1, had altered in vitro replication and in vivo biological properties. A more comprehensive characterization of RM1 was carried out in the present project. We sought to highlight whether events of such integrations occur also in the bird, in vivo. For that, we had first to determine the prevalence of dually-infected individual birds in commercial flocks, as no systematic survey has been yet reported. Surprisingly, about 25% of the commercial flocks infected with avian oncogenic viruses had a multiple virus infection and 5% of the total samples ana lysed had multiple virus sequences. Then, we aimed to evaluate and characterize biologically and molecularly the resulting recombinants, if formed, and to analyse the factors that affect these events (virus strains, type and age of birds and time interval between the infection with both viruses). The perception of retrovirus insertions into herpesviruses in vivo is not banal, as the in vivo and in vitro systems differ in the viral-target cells, lymphocytes or fibroblasts, in the MDV-replicative type, transforming or productive, and the immune system presence. We realized that previous methods employed to study in vitro created recombinant viruses were not adequate for the study of samples taken directly from the bird. Therefore, the Hot Spot-combined PCR was developed based on the molecularly known RM1 virus. Also, the PFGE that was used for tissue cultured-MDV separation was inefficient for separating MDV from organs, but useful with feather tips as a source of bird original MDV. Much attention was dedicated now to feathers, because if a recombinant virus would be formed in vivo, its biological significance would be evident by horizontal dissemination through the feathers. Major findings were: a) not only in vitro, but also in vivo MDV and retrovirus co-infections lead to LTR integrations into MDV. That was shown by the detection of chimeric molecules. These appeared in low quantities and as quasispecies, thus interfering with sequence analysis of cloned gel-purified chimeric molecules. Mainly inserts were located in the repeat long MDV fragments. In field birds chimeric molecules were detected at a lower frequency (2.5%) than in experimentally infected birds (30-50%). These could be transmitted experimentally to another birds by inoculation with chimeric molecules containing blood. Several types of chimeric molecules were formed, and same types were detected in birds infected by a second round. To reproduce viral integrations, in vivo infection trials were done with field inoculate that contained both viruses, but the chimeric molecule yield was undetectable.
