“The Russian graves”: I.A. Sikoskij and V.V. Rosanov on psychology of “sectarianism”.
No full textThe article contains a comparative analysis of approaches to the study of “sects” developed at the end of 19th the beginning of 20th century within the frame of Russian psychiatry on the one hand and within Russian religious thought on the other. The psychiatrist line is represented by I.A. Sikoskij 1842 1919, one of the main actors of Russian psychology and psychiatry of that time, meanwhile religious philosophical line — by famous journalist and thinker V.V. Rosanov 1856 1919. In the first part of the article Sikorsrij’s studies of marginal religiosity: cases of movement of so called “malevantsi” and mass selfburies near Tiraspol — are under discussion. The author analyses presuppositions and results of those studies, general approach of Sikorsij, the role of such metaphors as “suggestion”, “infection”, “psychological epidemic” in his explanation model, his hidden references to ideas of Tard and Lebon, his criteria of distinction of normal and marginal religiosity, role of his ideas in development of psychiatrist approach as a whole. Discussions around Sikorsij’s publications are considered. In the second part Rosanov’s texts devoted to the same theme become the subject of analyses. Basic principles of Rosanov’s approaches to the analyses of religious problematic in general and marginal religiosity in particular are explicated. The author points out an influence of context of polemics on concrete evaluations and assertions of Rosanov. Text “Russian graves” Rosanov’s replica on Sikorskij’s essay devoted to Tirapol’s tragedy is in focus. The subjects of analyses are: special features of form and stylistics of Rosanov’s text, application of general methodological principles described above, the usage of the case in antichristian polemics of the writer. The approach demonstrated by Rosanov and his criticism of “psychiatry” are putting into the context of development of humanities in the 19 century. Some proposals connected to the place of approaches described in the development of Russian psychology of religion are suggested in conclusion
Obtaining single-cycle pulses from a mode-locked laser
No full textIn all existing mode-locked lasers, the ultimate limit on the output pulse duration is set by the bandwidth of the gain medium. Yet the technique of coherent mode locking allows one to generate broadband pulses from a laser with a linearly narrowband active medium by exploiting the coherent properties of the amplifier. In this work we numerically demonstrate how to use this technique for the generation of single-cycle pulses directly from a mode-locked oscillator
Maxwell-Drude-Bloch dissipative few-cycle optical solitons
No full textWe study the propagation of few-cycle pulses in a two-component medium consisting of nonlinear amplifying
and absorbing two-level centers embedded into a linear and conductive host material. First we present a linear
theory of propagation of short pulses in a purely conductive material and demonstrate the diffusive behavior for the
evolution of the low-frequency components of the magnetic field in the case of relatively strong conductivity. Then,
numerical simulations carried out in the frame of the full nonlinear theory involving the Maxwell-Drude-Bloch
model reveal the stable creation and propagation of few-cycle dissipative solitons under excitation by incident
femtosecond optical pulses of relatively high energies. The broadband losses that are introduced by the medium
conductivity represent the main stabilization mechanism for the dissipative few-cycle solitons
[fat Absorption After Total Gastrectomy In Rats Submitted To Roux-en-y Or Rosanov-like Double-transit Technique].
No full textSteatorrhea is one of the most common complications in reconstruction after total gastrectomy. Many reconstruction techniques after total gastrectomy have been developed in order to avoid these undesirable effects, but each one of them has some inconvenience. In this experiment, a modified Rosanov technique that keeps duodenal transit, evaluation of fat absorption after gastrectomy was tested. Three groups of rats with the same characteristics were used. Total gastrectomy was performed in two groups: one was operated on and transit was reestablished by the Roux-en-Y technique (group Y), while the other was submitted to the modified Rosanov technique (group R). Following surgery, a handmade hyper fatty diet (11% of fat) was offered. A third group (control - group C) was not operated but was submitted to the same conditions of the other groups, and used for reference steatocrit values. The animals underwent laparotomy 14 days after surgery and had their feces collected from cecum to determine their steatocrit by analysis of their values. Steatocrit values for groups R and C (mean 5.16% and 4.15% respectively) were similar (p > 0.1), while group Y had significantly higher values (mean = 28.18%, p = 0.0001 - p < 0,05). This was attributed to the fact that group R animals had their duodenal transit patent, decreasing the complications expected in the Roux-en-Y reconstruction. Steatorrhea in the modified Rosanov technique was similar to the control group, while Roux-en-Y reconstruction presented higher steatorrhea and fat malabsorption.21380-
Generation of unipolar pulses from nonunipolar optical pulses in a nonlinear medium
No full textA unipolar electromagnetic pulse is a pulse with nonzero value of the static component of the Fourier spectrum of its real electric field (and not its envelope). We show how to efficiently generate unipolar pulses through propagation of an initially nonunipolar pulse in a nonlinear optical medium. One of the major results is the demonstration that the static component can only be generated in equal portions between the forward- and backward-traveling waves in the presence of nonlinear backscattering in a nonlinear medium

Várias técnicas de reconstrução após gastrectomia total foram descritas para que se pudesse evitar esses efeitos indesejáveis, mas cada uma apresentou seus inconvenientes. Nesse estudo foi avaliada a técnica descrita por Rosanov com uma pequena modificação, que mantém o trânsito através do duodeno, para avaliar a absorção de gorduras. MÉTODOS: Foram utilizados três grupos de ratos Wistar machos, com peso e características semelhante. Dois grupos foram submetidos à gastrectomia total: o primeiro teve sua reconstrução com técnica de Y de Roux (grupo Y), e o segundo com Rosanov modificado (grupo R). Após a cirurgia, foi introduzida dieta com teor de gorduras conhecido (11%). Um terceiro grupo (grupo C) esteve sob mesmas condições dos outros animais, sem ter sido submetido à cirurgia, e foi utilizado como grupo controle para o esteatócrito. Após 14 dias, antes de serem sacrificados, foram submetidos a laparotomia para coleta de fezes do ceco e dosagem de esteatócrito. Os valores de esteatócrito foram analisados estatisticamente pelo método de Kruskal-Wallis. RESULTADOS: O esteatócrito dos grupos R (média = 5,16%) e C (média = 4,15%) foram semelhantes (p > 0,1), enquanto o grupo Y teve valores significativamente maiores (média = 28,18%, p-=0.0001 - p< 0,05). CONCLUSÃO: A gastrectomia total com reconstrução tipo Rosanov modificada mostrou esteatorréia semelhante ao grupo controle, enquanto a reconstrução tipo Y de Roux apresentou esteatorréia mais elevada, e portanto malabsorção de gordura
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Avaliação da absorção de gordura apos gastrectomia total em ratos com reconstrução tipo Y de Roux e em duplo transito tipo Rosanov modificado
No full textOrientador : Luiz Roberto LopesDissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Ciências MédicasResumo: Introdução - Uma das principais complicações tardias da gastrectomia total com reconstrução de trânsito excluindo duodeno (Y de Roux) é a esteatorréia. Entre seus fatores causais estão o supercrescimento bacteriano do delgado, mistura ineficaz dos alimentos com enzimas, diminuição do estímulo neuro-hormonal para o pâncreas e diminuição da superfície absortiva por deixar alça intestinal excluída do trânsito. Muitas técnicas de reconstrução pós-gastrectomias total foram descritas para que se pudesse evitar esses efeitos indesejáveis, mas cada uma apresentou seus inconvenientes. Nesse estudo foi avaliada a técnica descrita por Rosanov com uma pequena modificação, que mantém o trânsito através do duodeno, para avaliar a absorção de gorduras. Objetivo - Avaliar em ratos a absorção de gorduras e o peso após gastrectomia total, comparando as técnicas utilizadas para reconstrução de trânsito: tipo Y de Roux e tipo Rosanov modificado. Método ¿ Foram utilizados 3 grupos de ratos Wistar machos, com peso semelhante. Dois grupos foram submetidos à gastrectomia total: o primeiro teve sua reconstrução com técnica de Y de Roux (grupo Y), e o segundo com Rosanov modificado (grupo R). Após a cirurgia, foi introduzida dieta com teor de gorduras conhecido (11%). Um terceiro grupo (controle) foi submetido às mesmas condições dos outros animais, sem ter sido submetido à cirurgia, e foi utilizado como parâmetro para o esteatócrito e peso pós-operatório. Após 14 dias, antes de serem sacrificados, foram submetidos a laparotomia para coleta de fezes do ceco e dosagem de esteatócrito. Os valores de esteatócrito e a perda de peso foram analisados estatisticamente pelo método de Kuskal-Wallis. Resultados ¿ A perda de peso foi semelhante nos grupos Y e C (p-valor>0,1), e maior no grupo R (p-valor=0,0001). O esteatócrito dos grupos R (média = 5,16%) e C (média = 4,15%) foram semelhantes (p-valor>0,1), enquanto o grupo Y teve valores significativamente maiores (média = 28,18%, p-valor=0.0001). Conclusão - A gastrectomia total com reconstrução tipo Rosanov modificada mostrou esteatorréia semelhante ao grupo controle, enquanto a reconstrução tipo Y de Roux apresentou menor esteatorréia que os grupos controle e Rosanov. Com relação ao peso, houve perda de peso maior no grupo operado com técnica de Rosanov modificada, que nos grupos controle e operado com reconstrução tipo Y de Roux, que foram semelhantes. Esta ocorrência foi atribuída ao fato de os animais do grupo R possuírem passagem alimentar pelo duodeno, que continua no trânsito intestinal, diminuindo as complicações previstas na reconstrução tipo Y de RouxAbstract: Introduction - Steatorrhea is one of the most common complications of duodenum-exclusion reconstruction after total gastrectomy (Roux-en-Y). Among its causes are: small bowel bacterial overgrowth, inefficient food-enzime mixing, insufficient neuro-hormonal pancreatic stimulation, shortening of absorption surface, due to leaving excluded part of the bowel. Many post-total gastrectomy reconstruction techniques have been developed, in order to avoid these undesirable effects, but each of them has its inconvenience. In this experiment, we tested a slightly modified Rosanov technique, which keeps duodenal transit, to evaluate fat absorption after gastrectomy. Objective ¿Evaluate the intestinal post-total gastrectomy steatorrhea comparing the Roux-en-Y and the modified Rosanov techniques. Methods ¿ Three groups of rats of the same age, weight and species were used. Total gastrectomy was performed in two groups: the first one was operated and transit was reestablished by the Roux-en-Y technique (group Y), while the second, by the modified Rosanov technique. After surgery a 11% (hyperfatty) handmade diet was offered. A third group (control - group C) was not taken to surgery, but was submitted to the same conditions of the other groups, and was used as reference for steatocrit and post-operative weight values. The animals were taken to laparotomy 14 days after surgery and had their feces collected from cecum, and their steatocrit determined. Results were provided by analysis of weight loss and steatocrit values. Results ¿ Weight loss was similar in groups Y and C (p-value > 0.1), and higher in group R (p-value = 0.0001) Groups R and C steatocrit values (mean 5.16% and 4.15% respectively) were similar (p-value > 0.1), while group Y had significantly higher values (mean = 28,18%, p-value = 0.0001). This was attributed to the fact that the group R animals had their duodenal path patent, decreasing the complications expected in the Roux-en-Y reconstruction. Conclusion ¿ Steatorrhea in the modified Rosanov technique was similar to control group, while Roux-en-Y reconstruction had its values higher. Weight loss was lower in the control and Roux-en-Y group, when compared to modified Rosanov techniqueMestradoCirurgiaMestre em Cirurgi
