Combined cerebellar and bilateral cervical posterior spinal artery stroke demonstrated on MRI

Combined cerebellar and spinal ischemic stroke is a rare, critical condition. We report a patient with combined cerebellar and bilateral posterolateral cervical spinal cord infarction due to bilateral stenosis of the vertebral arteries. MRI is the method of choice for imaging this condition; diffusion-weighted imaging of the spinal cord gives reliable results

Population ecology of the intertidal anemone Actinia tenebrosa Farquhar (Cnidaria: Anthozoa)

The population ecology of the intertidal anemone Actinia tenebrosa Farquhar, 1898, was studied at Kaikoura, New Zealand, from 1972 to 1976 inclusive. Chapters in this thesis discuss geographical distribution of the species, synonymy, reproduction, pedal locomotion, intraspecific aggression, population dynamics and longevity

Анализ параметров работы установки для обогащения лития по литию - 7 амальгамно - обменным способом

Работа посвящена анализу эффективности протекания процесса обогащения лития по тяжелому изотопу литий-7 в колоннах в зависимости от внешних потоков, температуры и других параметров.The work is devoted to the analysis of the efficiency of the process of lithium enrichment in the heavy lithium-7 isotope in columns depending on external flows, temperature, and other parameters

Cerebral differences in explicit and implicit emotional processing - An fMRI study

The processing of emotional facial expression is a major part of social communication and understanding. In addition to explicit processing, facial expressions are also processed rapidly and automatically in the absence of explicit awareness. We investigated 12 healthy subjects by presenting them with an implicit and explicit emotional paradigm. The subjects reacted significantly faster in implicit than in explicit trials but did not differ in their error ratio. For the implicit condition increased signals were observed in particular in the thalami, the hippocampi, the frontal inferior gyri and the right middle temporal region. The analysis of the explicit condition showed increased blood-oxygen-level-dependent signals especially in the caudate nucleus, the cingulum and the right prefrontal cortex. The direct comparison of these 2 different processes revealed increased activity for explicit trials in the inferior, superior and middle frontal gyri, the middle cingulum and left parietal regions. Additional signal increases were detected in occipital regions, the cerebellum, and the right angular and lingual gyrus. Our data partially confirm the hypothesis of different neural substrates for the processing of implicit and explicit emotional stimuli. Copyright (c) 2007 S. Karger AG, Basel

Разработка рекомендаций к системе учета и контроля ядерных материалов, радиоактивных веществ и радиоактивных отходов в Томском политехническом университете

В работе представлен анализ существующей системы государственного учета и контроля ядерных материалов, радиоактивных веществ и радиоактивных отходов. На основе проведенного анализа текущего состояния нормативно-правовых документов установлено несоответствие и предложена рекомендация по изменению ряда документов ТПУ в области учета и контроля ядерных материалов.The paper presents an analysis of the existing system of state accounting and control of nuclear materials, radioactive substances and radioactive waste. Based on the analysis of the current state of regulatory documents, a discrepancy was established and a recommendation was proposed to amend a number of TPU documents in the field of accounting and control of nuclear materials

Julian of Norwich and her children today: Editions, translations and versions of her revelations

The viability of such concepts as "authorial intention," "the original text," "critical edition" and, above all, "scholarly editorial objectivity" is not what it was, and a study of the textual progeny of the revelations of Julian of Norwich--editions, versions, translations and selections--does little to rehabilitate them. Rather it tends to support the view that a history of reading is indeed a history of misreading or, more positively, that texts can have an organic life of their own that allows them to reproduce and evolve quite independently of their author. Julian's texts have had a more robustly continuous life than those of any other Middle English mystic. Their history--in manuscript and print, in editions more or less approximating Middle English and in translations more or less approaching Modern English--is virtually unbroken since the fifteenth century. But on this perilous journey, many and strange are the clutches into which she and her textual progeny have fallen

Вплив нормального тиску на напружений стан гуми ступінчастого каната на робочому органі підйомної машини

Досліджено напружений стан гуми ступінчастого гумотросового каната у разі його застосування на підйомній машині з бобінним робочим органом та зі шківом тертя. Показано, що максимальні напруження в гумі залежать від конструкції каната та тиску, що виникає поміж шарами. Форма поперечного перерізу троса також впливає на напружений стан гуми.Исследовано напряженное состояние резины ступенчатого резинотросового каната в случае его применения на подъемной машине с бобинным рабочим органом и со шкивом трения. Показано, что максимальные напряжения в резине зависят от конструкции каната и давления, возникающего между слоями. Форма поперечного сечения троса также влияет на напряженное состояние резины.The stress-strain state of stepped rubber-rope cable in bobbin of winding and in pulley friction, are investigated. Shown that the maximum stress in the rubber depends on the design of the rope and the pressure appeared between the layers. Cable cross-sectional shape also affects to the stressstrain state of rubber
