    Four hundred seventeen fungi were isolated from 144 of the 163 Douglas-fir poles (ages 7 to 17 years and treatments CCA, penta and oil, or Cellon®) sampled from transmission lines or storage piles in New York and Pennsylvania. Microfungi predominated and comprised nearly 85% of all isolates. They were isolated primarily from treated zones and were most abundant in older CCA-treated poles in transmission lines. Antrodia carbonica and Postia placenta were the principal basidiomycete decayers and isolated primarily from untreated zones in CCA-treated poles. A limited number of white-rot fungi were isolated from the treated and untreated zones of several poles.Seven of the 12 principal microfungi were established to have soft-rot capabilities. Soft rot was detected anatomically in 23 of the 144 poles in transmission lines. In most cases it was superficial and limited to several outer annual rings; however, it was severe in older CCA-treated poles and involved all of the treated zone and extended several centimeters radially into the untreated zone. Also, soft rot was detected anatomically and soft-rot fungi culturally, in 8 of 12 13-year-old CCA-treated poles that had been fumigated with Vapam 5 or 6 years previously. None was detected in the fumigated penta-treated poles.These data suggest that soft-rot fungi play an important role in decay development in the treated groundline zone of utility poles and should be considered in decay detection programs (culturally) and decisions on the timing of remedial treatments

    Mobilizing the emergence of Phronetic TechnoScienceSocieties:low-carbon e-mobility in China

    TechnoScienceSociety (TSS) spells the wholesale reorganization of the constellation of related concepts that together make up the very common-sense meaning of ‘politics’ and ‘government’, not least of which today are knowledge, science, technology and society, all of which are currently founded on essentially literal, dualistic not pragmatic, processual grounds. We argue that grappling with TSS and a politics of TSS demands a shift broadly from a universalist (if possibly critical) epistemo-politics of critique or criticism to an onto-politics of situated practical wisdom (phronesis). Important pointers in this direction come from existing work in actor network theory (ANT)-inspired STS. But while useful starting points, this work is also insufficient in some key regards, to the point that we must now move beyond it. In particular, the need for a shift to a situated, processual and practically engaged perspective applies no less to discussions such as this in STS. We here trace out some of the argument for, and consequences of, that move. The argument proceeds as follows. First we consider the after-ANT argument of ontological politics and how this demands a break with the familiar epistemological and ‘one world’ politics still dominating contemporary discourse, mainstream and critical. Then we consider some of the key problems with this conception of ontological politics vis-à-vis the predicament of an emerging TSS. This includes a brief discussion of an alternative perspective, of complex power/knowledge systems (CP/KS) within a phronetic onto-politics. Finally, we illustrate the arguments by analysing, using this CP/KS and onto-political perspective, a key case study of contemporary TSS: the ongoing attempts of innovation towards a transition in urban mobility system in China

    Interiorized Feminism and Gendered Nostalgia of The ‘Daughter Generation’ in Ning Ying's Perpetual Motion

    This is the author's accepted manuscript. The original publication is available at http://dx.doi.org/10.1386/jcc.5.3.253_1Ning Ying’s 2006 film Wuqiong dong/Perpetual Motion can be regarded as her first attempt to explore the genre of ‘women’s film’. Deviating from her previous neo-realist style, this film seeks to cultivate an alternative cinematic practice through developing a heavy-handed negative aesthetics. Ning Ying interiorizes the filmic exploration of female subjectivity in an enclosed time and space, which is constantly haunted by a spectral aesthetics characterized by audio-visual allusions to loss, grave, ruins and ghosts. However, the film’s radical content and alternative aesthetics are, ironically, packaged in prevailing consumer aesthetics and commodity fetishism on and off the silver screen. All these competing drives and accounts render the film a contested narrative constantly oscillating between avant-garde feminism and domestic melodrama, and between a register of disintegrating sisterhood and a celebrity scandal of adultery. This article examines the discursive and aesthetic innovations, contradictions and limits of Ning Ying’s cinematic feminism

    Investigation of cerebral autoregulation in the newborn piglet during anaesthesia and surgery

    The relationship between cerebral autoregulation (CA) and the neurotoxic effects of anaesthesia with and without surgery is investigated. Newborn piglets were randomly assigned to receive either 6 h of anaesthesia (isoflurane) or the same with an additional hour of minor surgery. The effect of the spontaneous changes in mean arterial blood pressure (MABP) on the cerebral haemodynamics (oxy- and deoxy-haemoglobin, HbO2 and Hb) was measured using transverse broadband near-infrared spectroscopy (NIRS). A marker for impaired CA, concordance between MABP and intravascular oxygenation (HbD = HbO2 - Hb) in the ultra-low frequency domain (0.0018-0.0083 Hz), was assessed using coherence analysis. Presence of CA impairment was not significant but found to increase with surgical exacerbation. The impairment did not correlate with histological outcome (presence of cell death, apoptosis and microglial activation in the brain)

    Axonal sensorimotor neuropathy in patients with ß-thalassaemia

    Methods: Thirty six patients with a mean age of 29.2±8.2 years and 17 healthy controls with a mean age of 27.6±9.1 were included in this study. Measurements included the neuropathy symptoms score (NSS), the neuropathy disability score (NDS) as well as nerve conduction studies of two motor (ulnar and peroneal) and two sensory (ulnar and sural) nerves of the right limbs. Results: A mainly sensory axonal polyneuropathy was present in 19 out of 36 patients (52.7%). Eight out of these 19 patients also had abnormal NDS values. The neuropathy correlated significantly with the age of the patients and the hematocrit. However, it did not correlate with the presence of antibodies against HCV, the ferritin levels, or with a history of transfusions, desferrioxamine treatment, or splenectomy. Conclusions: This study showed a high prevalence of a predominantly sensory neuropathy in patients with ß-thalassaemia. The electrophysiological data suggest that the underlying pathology is an axonopathy. Chronic hypoxia of the nerves resulting from severe anaemia may contribute to the pathogenesis of this neuropathy
