    ObjectiveSystemic lupus erythematosus (SLE), an autoimmune systemic disease with unknown etiology, affects virtually every part of the body; involvement of the central nervous system (CNS) is one of the major causes of morbidity and mortality in systemic lupus erythematosus (SLE) patients and is the least understood aspect of the disease. neutropenia is very uncommon in childhood lupus. True negative anti nuclear antibody (ANA) tests in patients with lupus are now very rare. The patient reported here was a 12-year-old girl with ANA negative lupus cerebritis who presented with left hemiparesia after a generalized seizure, with neutropenia observed during its course

    Summary An in vitro experiment was conducted to determine the effect of supplemental non-fiber carbohydrate (NFC) on the disappearance kinetics of cellulose (Ce) by mixed ruminal microorganisms. Non-supplemented or NFC supplemented cellulose (467 mg NFC/g cellulose as sucrose (CeSu) or starch (CeSt) or a 1:1 mixture of sucrose + starch (CeSuSt)) were incubated for 24, 48, and 96 h at 39°C. After each incubation time, pH, ammonia-N concentration and cellulose disappearance were measured. The disappearance kinetics rate of all samples was determined using first order exponential model of D (t) = D (i) .exp (-k. time) + I; where D (t) is potentially digestible fraction; D (i) is potentially digestible residues; k is digestion rate of cellulose (h -1 ) and I is indigestible fraction. In this experiment, inclusion of NFC to the rumen fluid medium resulted in a significant depression (P<0.01) in the extent of cellulose disappearance. The disappearance rate constant of cellulose was significantly higher (P<0.05) in non-supplemented samples as compared with those treatments containing NFC. The indigestible fraction of cellulose was significantly higher (P<0.05) for treatments containing sucrose or sucrose + starch as the source of supplemental NFC as compared with nonsupplemented cellulose. However, when starch was added, the indigestible fraction of cellulose was similar to those of non-supplemented samples. The inclusion of NFC resulted in a significant reduction (P<0.01) in pH of the medium, but had no significant effect (P>0.05) on ammonia-N concentration

    Abstract. The geometry of a system of second order differential equations is the geometry of a semispray, which is a globally defined vector field on T M . The metric compatibility of a given semispray is of special importance. In this paper, the metric associated with the semispray S is applied in order to study some types of foliations on the tangent bundle which are compatible with SODE structure. Indeed, sufficient conditions for the metric associated with the semispray S are obtained to extend to a bundle-like metric for the lifted foliation on T M . Thus, the lifted foliation converts to a Riemanian foliation on the tangent space which is adapted to the SODE structure. Particularly, the metric compatibility property of the semispray S is applied in order to induce SODE structure on transversals. Finally, some equivalent conditions are presented for the transversals to be totally geodesic

    HEARING LOSS RESULTING FROM NOISE EXPOSURE IN TEXTILE WORKERS

    Measurement and analysis of noise level in various frequency bands was carried out in a textile factory. It was shown that the noise level in various working places, particularly in the weaving workshop, was quite excessive comparing to the standards and so, it may very likely result in producing hearing loss in the workers. To determine the hearing loss of the workers due to excessive noise, 136 weavers were randomly selected and examined. However, the number of samples was not large enough to give reliable results. It was concluded that the intensive noise level in the weaving workshops may have produced considerable hearing loss in the workers. Large the expo­sure to noise, more the hearing loss was observed

    Discharge Estimation of Circular Sewer Using Combined Device of Weir-Sluice Gate

    Due to space constraints any access to a buried sewer conduit is seriously limited. In order to install the flow measurement devices, the space of manholes are the most appropriate places in a conduit. The conventional weir plates or sluice gates are usually used for flow measurements, however, these devices due to the nature of sewage, which contains sediments or floating objects are not suitable for flow measurements in sewer conduits. In a sewer conduit, the heavy solid particles tend to settle down behind a weir plate and floating objects accumulate behind a sluice gate, which both affects the accuracy of measurements by these devices. Therefore, the implementation of a combined system of weir-sluice gate at a cross section of conduit seems to be able to recover the defects of weirs and sluice gates. The application of this device in a circular cross section has not been received enough attention in the past. In the present paper the experimental results obtained from discharge measurement using combined weir-sluice gate system which allows simultaneously flow over and under a weir plate installed at the end of a sewer conduit are presented. The relationship between the experimental results and the theoretical flow which is a function of some geometric and hydraulic information of flow, are analyzed. Using statistical analysis of the obtained results of flow measurements accompanied with linear regression, an equation for discharge coefficient  is proposed. The efficiency of the proposed technique is high enough that the associated error is limited to 10%

    Pregermination treatment and germination characteristics of oriental beech (Fagus orientalis Lipsky) in the Caspian region

    Oriental beech is one of the most important tree species in the Caspian region that regeneratesnaturally.Seed pretreatment plays an important role in beech reforestation .For this reason the seeds ofthree different provenances; Gilan (Asalem), Nowshahr (Makarood), Gorgan (Cheshmeh gholgholy),across the Caspian region, were collected and after viability test (TTC) placed under cold stratification(for 8-19 weeks) to overcome dormancy. The results have shown that pregermination treatments haddesirable effects on seed germination. There were significant variations between three origins anddifferent treatment duration and germination characterstics. The Nowshahr and Gilan origins showedmore similarity

    Abnormalities in the processing of emotional prosody from single words in schizophrenia

    Background: Abnormalities in emotional prosody processing have been consistently reported in schizophrenia and are related to poor social outcomes. However, the role of stimulus complexity in abnormal emotional prosody processing is still unclear. Method: We recorded event-related potentials in 16 patients with chronic schizophrenia and 16 healthy controls to investigate: 1) the temporal course of emotional prosody processing; and 2) the relative contribution of prosodic and semantic cues in emotional prosody processing. Stimuli were prosodic single words presented in two conditions: with intelligible (semantic content condition—SCC) and unintelligible semantic content (pure prosody condition—PPC). Results: Relative to healthy controls, schizophrenia patients showed reduced P50 for happy PPC words, and reduced N100 for both neutral and emotional SCC words and for neutral PPC stimuli. Also, increased P200 was observed in schizophrenia for happy prosody in SCC only. Behavioral results revealed higher error rates in schizophrenia for angry prosody in SCC and for happy prosody in PPC. Conclusions: Together, these data further demonstrate the interactions between abnormal sensory processes and higher-order processes in bringing about emotional prosody processing dysfunction in schizophrenia. They further suggest that impaired emotional prosody processing is dependent on stimulus complexity.This work was supported by two grants awarded to A.P.P.: Post-Doctoral Grant no.
