Full Text Available OBJECTIVE: To analyze the results obtained by open-door laminoplasty using the Newbridge(r/Blackstone plate, in cases of myelopathy associated with cervical lordosis.METHODS: From December 2010 to October 2012, eight patients between the ages of 49 and 68 underwent open-door laminoplasty with the use of the Newbridge(r fixation system for maintenance and stabilization of the cervical laminoplasty. Minimum follow-up was four months. For the evaluation of quality of life the questionnaire SF-36 was applied at the following times: preoperative, one month and three months after surgery associated with the subjective assessment of the patient regarding satisfaction with the procedure and with the Nurick neurological scale applied prior to surgery and three months later.RESULTS: According to the SF-36, there was significant improvement in the domains functional ability, general health perceptions and emotional aspects over time; regarding physical limitations and social aspects there was no improvement in the first postoperative month, only in the third month. There were no statistically significant changes observed during the period covered by this study related to pain, vitality and mental health. According to Nurick scale, there was evidence of improvement in symptoms of cervical myelopathy. Based on the subjective evaluation of the patients, surprisingly, all patients were satisfied with the surgical procedure and the results.CONCLUSION: The open-door laminoplasty technique with rigid fixation to maintain the opening is useful in improving the symptoms of cervical myelopathy associated with lordosis, leading to improved quality of life and with a high degree of patient satisfaction and fewer complications.

Objective: To build a three-dimensional finite element models of a modified posterior cervical single open-door laminoplasty with short-segmental lateral mass screws fusion. Methods: The C(2)-C(7) segmental data were obtained from computed tomography (CT) scans of a male patient with cervical spondylotic myelopathy and spinal stenosis.Three-dimensional finite element models of a modified cervical single open-door laminoplasty (before and after surgery) were constructed by the combination of software package MIMICS, Geomagic and ABAQUS.The models were composed of bony vertebrae, articulating facets, intervertebral disc and associated ligaments.The loads of moments 1.5Nm at different directions (flexion, extension, lateral bending and axial rotation)were applied at preoperative model to calculate intersegmental ranges of motion.The results were compared with the previous studies to verify the validation of the models. Results: Three-dimensional finite element models of the modified cervical single open- door laminoplasty had 102258 elements (preoperative model) and 161 892 elements (postoperative model) respectively, including C(2-7) six bony vertebraes, C(2-3)-C(6-7) five intervertebral disc, main ligaments and lateral mass screws.The intersegmental responses at the preoperative model under the loads of moments 1.5 Nm at different directions were similar to the previous published data. Conclusion: Three-dimensional finite element models of the modified cervical single open- door laminoplasty were successfully established and had a good biological fidelity, which can be used for further study.

Open-door expansile cervical laminoplasty (ODECL) is an effective surgical technique in the treatment of multilevel cervical spondylotic myelopathy. In the present study, we reviewed the safety and short-term neurological outcome after expansile cervical laminoplasty in the treatment of acute central cord syndrome. We retrospectively reviewed our database over a 3-year period (January 1997-January 2001) and identified 69 surgically treated cervical spinal cord injuries, including 29 cases of acute traumatic central cord syndrome (ATCCS). Fifteen of these patients underwent expansile cervical laminoplasty, whereas 14 did not because of radiographic evidence of sagittal instability. We collected data on the preoperative and the immediate postoperative and 3-month neurological examinations. Neurological function was assessed using the Asia Spinal Injury Association (ASIA) grading system. We also reviewed the occurrence of complications and short-term radiological stability after the index procedure. The median age was 56 years. All patients had hyperextension injuries with underlying cervical spondylosis and stenosis in the absence of overt fracture or instability. The average delay from injury to surgery was 3 days. The preoperative ASIA grade scale was grade C, 8 patients, and grade D, 7 patients. There were no cases of immediate postoperative deterioration or at 3 months follow-up. Neurological outcome: 71.4% (10/14) of patients improved 1 ASIA grade when examined 3 months post injury. Surgical intervention consisting of ODECL can be safely applied in the subset of patients with ATCCS without instability who have significant cervical spondylosis/stenosis. Open-door expansile cervical laminoplasty is a safe, low-morbidity, decompressive procedure, and in our patients did not produce neurological deterioration.

Previous studies have identified the factors affecting the surgical outcome of cervical spondylotic myelopathy (CSM) following laminoplasty. Nonetheless, the effect of these factors remains controversial. It is unknown about the association between pre-operative cervical spinal cord morphology and post-operative imaging result following laminoplasty. The goal of this study is to analyze the impact of pre-operative cervical spinal cord morphology on post-operative imaging in patients with CSM. Twenty-six patients with CSM undergoing open-door laminoplasty were classified according to pre-operative cervical spine bony alignment and cervical spinal cord morphology, and the results were evaluated in terms of post-operative spinal cord posterior drift, and post-operative expansion of the antero-posterior dura diameter. By the result of study, pre-operative spinal cord morphology was an effective classification in predicting surgical outcome - patients with anterior convexity type, description of cervical spinal cord morphology, had more spinal cord posterior migration than those with neutral or posterior convexity type after open-door laminoplasty. Otherwise, the interesting finding was that cervical spine Cobb's angle had an impact on post-operative spinal cord posterior drift in patients with neutral or posterior convexity type spinal cord morphology - the degree of kyphosis was inversely proportional to the distance of post-operative spinal cord posterior drift, but not in the anterior convexity type. These findings supported that pre-operative cervical spinal cord morphology may be used as screening for patients undergoing laminoplasty. Patients having neutral or posterior convexity type spinal cord morphology accompanied with kyphotic deformity were not suitable candidates for laminoplasty. Copyright © 2015 Elsevier B.V.

Full Text Available Laminoplasty is a standard technique for treating patients with multilevel cervical spondylotic myelopathy. Modified expansive open-door laminoplasty (MEOLP preserves the unilateral paraspinal musculature and nuchal ligament and prevents facet joint violation. The purpose of this study was to elucidate the midterm surgical outcomes of this less invasive technique. We retrospectively recruited 65 consecutive patients who underwent MEOLP at our institution in 2011 with at least 4 years of follow-up. Clinical conditions were evaluated by examining neck disability index, Japanese Orthopaedic Association (JOA, Nurick scale, and axial neck pain visual analog scale scores. Sagittal alignment of the cervical spine was assessed using serial lateral static and dynamic radiographs. Clinical and radiographic outcomes revealed significant recovery at the first postoperative year and still exhibited gradual improvement 1–4 years after surgery. The mean JOA recovery rate was 82.3% and 85% range of motion was observed at the final follow-up. None of the patients experienced aggravated or severe neck pain 1 year after surgery or showed complications of temporary C5 nerve palsy and lamina reclosure by the final follow-up. As a less invasive method for reducing surgical dissection by using various modifications, MEOLP yielded satisfactory midterm outcomes.

Study Design Systematic review. Study Rationale Numerous cervical laminoplasty techniques have been described but there are few studies that have compared these to determine the superiority of one over another. Clinical Questions The clinical questions include key question (KQ)1: In adults with cervical myelopathy from ossification of the posterior longitudinal ligament (OPLL) or spondylosis, what is the comparative effectiveness of open door cervical laminoplasty versus French door cervical laminoplasty? KQ2: In adults with cervical myelopathy from OPLL or spondylosis, are postoperative complications, including pain and infection, different for the use of miniplates versus the use of no plates following laminoplasty? KQ3: Do these results vary based on early active postoperative cervical motion? Materials and Methods A systematic review of the English-language literature was undertaken for articles published between 1970 and March 11, 2013. Electronic databases and reference lists of key articles were searched to identify studies evaluating (1) open door cervical laminoplasty and French door cervical laminoplasty and (2) the use of miniplates or no plates in cervical laminoplasty for the treatment of cervical spondylotic myelopathy or OPLL in adults. Studies involving traumatic onset, cervical fracture, infection, deformity, or neoplasms were excluded, as were noncomparative studies. Two independent reviewers (A.L.R., J.R.D.) assessed the level of evidence quality using the Grades of Recommendations Assessment, Development and Evaluation system, and disagreements were resolved by consensus. Results We identified three studies (one of class of evidence [CoE] II and two of CoE III) meeting our inclusion criteria comparing open door cervical laminoplasty with French door laminoplasty and two studies (one CoE II and one CoE III) comparing the use of miniplates with no plates.

To compare the clinical and radiological outcomes between skipped-level and all-level plating for cervical laminoplasty. Patients with cervical spondylotic myelopathy (CSM) treated by open-door laminoplasty with minimum 2-year postoperative follow-up were included. All patients had opening from C3-6 or C3-7 and were divided into skipped-level or all-level plating groups. Japanese Orthopaedic Association (JOA) scores and canal measurements were obtained preoperatively, immediate (within 1 week) postoperatively, and at 2, 6 weeks, 3, 6 and 12 months postoperatively. Paired t test was used for comparative analysis. Receiver operating characteristic analysis was used to determine the canal expansion cutoff for spring-back closure. A total of 74 subjects were included with mean age of 66.1 ± 11.3 years at surgery. Of these, 32 underwent skipped-level plating and 42 underwent all-level plating. No significant differences were noted between the two groups at baseline and follow-up. Spring-back closure was observed in up to 50% of the non-plated levels within 3 months postoperatively. The cutoff for developing spring-back closure was 7 mm canal expansion for C3-6. No differences were observed in JOA scores and recovery rates between the two groups. None of the patients with spring-back required reoperation. There were no significant differences between skipped-level and all-level plating in terms of JOA or recovery rate, and canal diameter differences. This has tremendous impact on saving costs in CSM management as up to two plates per patient undergoing a standard C3-6 laminoplasty may be omitted instead of four plates to every level to achieve similar clinical and radiological outcomes.

For three or more involved cervical levels, there is a debate over which approach yields the best outcomes for the treatment of multilevel cervical degenerative disease. Our objective is to compare the radiological and clinical outcomes of two treatments for multilevel cervical degenerative disease: anterior cervical discectomy and fusion (ACDF) versus plate-only open-door laminoplasty (laminoplasty). Patients were randomized on a 1:1 randomization schedule with 17 patients in the ACDF group and 17 patients in the laminoplasty group. Clinical outcomes were assessed by a visual analog scale (VAS), Japanese Orthopedic Association (JOA) scores, operative time, blood loss, rates of complications, drainage volume, discharge days after surgery, and complications. The cervical spine curvature index (CI) and range of motion (ROM) were assessed with radiographs. The mean VAS score, the mean JOA score, and the rate of complications did not differ significantly between groups. The laminoplasty group had greater blood loss, a longer operative time, more drainage volume, and a longer hospital stay than the ACDF group. There were no significant differences in the CI and ROM between the two groups at baseline and at each follow-up time point. ROM in both groups decreased significantly after surgery. Both ACDF and laminoplasty are effective and safe treatments for multilevel cervical degenerative disease. ACDF causes fewer traumas than laminoplasty.

Methods: We retrospectively reviewed 49 patients with multilevel CSM who had undergone expansive open-door laminoplasty with lateral mass screws fixation and fusion in our hospital between February 2008 and February 2012. The average follow-up period was 4.6 years. The clinical data of patients, including age, sex, operation records, pre- and postoperation Japanese Orthopedic Association (JOA scores, cervical spine canal stenosis, and cervical curvature, were collected. Increased signal intensity (ISI on T2-weighted magnetic resonance imaging and ossification of the posterior longitudinal ligament were also observed. Paired t-test was used to analyze the treatment effectiveness and recovery of neuronal function. The prognostic factors were analyzed with multivariable linear regression model. Results: Forty-nine patients with CSM with a mean age of 59.44 years were enrolled in this study. The average of preoperative JOA score was 9.14±2.25, and postoperative JOA score was 15.31±1.73. There was significant difference between the pre- and postoperative JOA scores. The clinical improvement rate was 80.27%. On follow-up, five patients had complaints of neck and shoulder pain, but no evidence of C5 nerve palsy was found. Developmental cervical spine canal stenosis was present in all patients before surgery. Before surgery, ISI was observed in eight patients, while ossification of the posterior longitudinal ligament was found in 12 patients. The average of preoperative cervical

Open-door laminoplasty is a useful operation in the surgical management of cervical myelopathy with favorable outcomes and relatively low complications. One potential undesirable outcome is a decrease in cervical lordosis postoperatively. It is unknown whether the most proximal level undergoing laminoplasty affects the magnitude of loss of lordosis. This study aimed to compare the loss of cervical lordosis postoperatively in patients for whom the most proximal level undergoing laminoplasty is C3 versus C4. A retrospective radiographic review at an academic center was carried out. A total of 65 patients at a single institution who underwent plated open door laminoplasty for cervical myelopathy by multiple surgeons over a 5-year period were included. The primary outcome was change in cervical lordosis, which was the difference in C2-T1 Cobb angle between the postoperative and preoperative films. Patients were divided into two groups based on the most proximal vertebral level undergoing laminoplasty. There were 49 patients who underwent laminoplasty beginning at C3, whereas 16 patients underwent laminoplasty beginning at C4. The C2-T1 Cobb angle was measured on the preoperative film and on the final postoperative follow-up film. The difference between these values was calculated for each patient, and the mean of the differences for the C3 group was compared with that of the C4 group. When C3 was the proximal plated laminoplasty level, loss of lordosis averaged 9°. In contrast, when C4 was the proximal plated level, loss of lordosis was significantly less and averaged only 3° (p=.047). In the group as a whole, mean preoperative lordosis was 18° compared with 11° postoperatively, for an overall 7° loss of lordosis. Starting the laminoplasty at C4 led to significantly less loss of lordosis than starting at C3. When the pattern of spinal cord compression does not require laminoplasty at C3, consideration should be given to making C4 the most cephalad laminoplasty

The purpose of this study is to evaluate the efficacy of spinal cord decompression surgery for cervical spinal cord injury without fracture or dislocation of the spinal column. Twenty-nine patients treated by expansive open-door laminoplasty are the subjects to this study. Severity of neurological deficit was assessed by the Japanese Orthopaedic Association (JOA) scoring system. Therapeutic outcome was evaluated by the recovery rate of JOA score. Seventeen patients were treated by surgically during the acute phase (within three months after injury), and the remaining 12 were in chronic phase (after 3 months). The recovery rate showed no significant difference between the two groups (46.9% vs. 34.0%). In 16 patients, the lesion responsible for spinal cord damage was recognized as a change of the intramedullary signal intensity on MRI, which was most frequently located at C3/4 level. In 7 out of the 16 patients, the most stenotic level agreed with recognized cord injury on MRI, and in the remaining 9 patients, it did not. The recovery rate showed no significant difference between the two groups (57.3% vs. 31.1%). Even if the neurological dysfunction has been present more than 3 months and spontaneous improvement reaches plateau, or spinal cord injury level recognized as a signal intensity change on MRI is not stenotic, there is still some possibility for improving the neurological function through surgery.

Expansive open-door laminoplasty (EOLP) is a useful technique for multiple-level cervical spondylotic myelopathy. The common postoperative complications of EOLP include moderate to severe neck pain, loss of cervical lordosis, decrease of cervical range of motion, and C5 palsy. We modified the surgical technique to lessen these complications. This study is aimed to elucidate the efficacy of modified techniques to lessen the complications of traditional procedures. We collected data from 126 consecutive patients treated at our institution between August 2008 and December 2012. Of these, 66 patients underwent conventional EOLP (CEOLP) and the other 60 patients underwent modified EOLP (MEOLP). The demographic and preoperative data, axial pain visual analog scale scores at 2 weeks and 3 months postoperatively, clinical outcomes evaluated using Nurick score and Japanese Orthopedic Association recovery rate at 12 months postoperatively, and radiographic results assessed using plain films at 3 months and 12 months postoperatively for both groups were compared and analyzed. There were no significant differences regarding the preoperative condition between the CEOLP and MEOLP groups (p > 0.05). The Japanese Orthopedic Association recovery rate of the MEOLP group was 70.3%, comparable to the result of the other group (70.2%). Postoperative axial neck pain, loss of range of motion, and loss of lordosis of cervical curvature decreased significantly in the MEOLP group (p cervical spondylotic myelopathy, which decreases postoperative complications effectively.

A retrospective case-controlled study. Open-door laminoplasty has been successfully used to address cervical spondylotic myelopathy and ossification of the posterior longitudinal ligament. Two common implants include rib allograft struts and metallic miniplates. The goals of this study were to compare outcomes, complications, and costs associated with these 2 implants. A retrospective review was done on 51 patients with allograft struts and 55 patients with miniplates. Primary outcomes were neck visual analog scale (VAS) pain scores and Nurick scores. Secondary outcomes included length of the procedure, estimated blood loss, rates of complications, and the direct costs associated with the surgery and inpatient hospitalization. There were no differences in demographic characteristics, diagnoses, comorbidities, and preoperative outcome scores between the 2 treatment groups. Mean follow-up was 27 months. The postoperative neck VAS scores and Nurick scores improved significantly from baseline to final follow-up for both groups, but there was no difference between the 2 groups. The average length of operation (161 vs. 136 min) and number of foraminotomies (2.7 vs. 1.3) were higher for the allograft group (P=0.007 and 0.0001, respectively). Among the miniplate group, there was no difference in complications but a trend for less neck pain for patients treated without hard collar at final follow-up (1.8 vs. 2.3, P=0.52). The mean direct costs of hospitalization for the miniplate group were 15% higher. Structural rib allograft struts and metallic miniplates result in similar improvements in pain and functional outcome scores with no difference in the rate of complications in short-term follow-up. Potential benefits of using a plate include shorter procedure length and less need for postoperative immobilization. When costs of bracing and operative time are included, the difference in cost between miniplates and allograft struts is negligible.

To identify whether expansive open-door laminoplasty (Lam) is more appropriate than laminectomy and instrumented fusion (LIF) for cases with ossification of the posterior longitudinal ligament (OPLL) and straight cervical lordosis. A total of 67 cases were included and divided into Group Lam (n = 32) and Group LIF (n = 35), and the mean follow-up periods were 38 and 42 months, respectively. The cervical lordosis was elevated by C2-7 Cobb angle and cervical sagittal balance by C2-C7 sagittal vertical axis (SVA). Japanese Orthopedic Association (JOA), neurological recovery rate (RR) being calculated by the JOA, visual analog scale (VAS) and neck disability index (NDI) were used to assess clinical outcomes. Differences in general data between two groups were not significant. Total blood loss and operation duration in Group Lam were both significantly less than that in the Group LIF. By the final follow-up, the cervical lordosis significantly decreased in Group Lam and increased in Group LIF, the SVA significantly increased in Group Lam and kept unchanged in Group LIF, and the JOA, VAS, NDI significantly improved in both groups. Although there was no significant difference in RR between the two groups, cases in Group Lam had significantly larger incidence of postoperative kyphosis and kyphotic change rate, and less VAS, NDI and incidence of axial pain than cases in Group LIF. When compared with the LIF, the Lam is recommended for cases with OPLL and straight cervical lordosis when taking comparable neurological recovery, less axial pain and better neck function improvement into consideration.

Piezosurgery is a relatively new osteotomy technique using microvibrations of scalpels at ultrasonic frequencies to perform safe and effective osteotomies without damage to adjacent soft tissue, which is widely used in spinal, oral, and maxillofacial surgery. We hypothesized that such a device could also be useful in cervical laminoplasty. The purpose of this study was to compare the safety and efficacy of a piezosurgery device with those of a highspeed drill in cervical laminoplasty. A prospectively randomized clinical study was designed. Forty-two consecutive patients were enrolled in the study. All patients underwent modified expansive open-door laminoplasty and were randomly divided into 2 groups according to the instrument for transection of the lamina, using high-speed drill (drill group) or piezosurgery device (piezosurgery group). The operation time, intraoperative blood loss, and postoperative drainage were recorded. Japanese Orthopedic Association (JOA) score and visual analogue scale (VAS) as clinical assessments were quantified. No significant difference was observed in the operation time between the 2 groups. In the piezosurgery group, there were less loss of the intraoperative blood and postoperative drainage compared with the drill group. However, clinical results (VAS and JOA scores) showed no significant difference between both groups during the all follow-up periods. The piezosurgery is a useful instrument and at least as safe and efficacious as the conventional high-speed drill in cervical laminoplasty.

Study Design Prospective cohort study. Objective To clarify long-term surgical outcomes of C3-6 laminoplasty preserving muscles attached to the C2 and C7 spinous processes in patients with cervical spondylotic myelopathy (CSM). Methods Twenty patients who underwent C3-6 open-door laminoplasty for CSM and who were followed for 8 to 10 years were included in this study. Myelopathic symptoms were assessed using Japanese Orthopaedic Association (JOA) score. Axial neck pain was graded as severe, moderate, or mild. C2-7 angle was measured using lateral radiographs of the cervical spine before surgery and at final follow-up. Results Mean JOA score before surgery (11.7) was significantly improved to 15.2 at the time of maximum recovery (1 year after surgery), declining slightly to 14.9 by the latest follow-up. Late deterioration of JOA score developed in eight patients, but was unrelated to the cervical spine lesions in each case. No patient suffered from prolonged postoperative axial neck pain at final follow-up. The mean C2-7 angle before surgery (13.8 degrees) significantly increased to 19.2 degrees at final follow-up. Conclusions C3-6 laminoplasty preserving muscles attached to the C2 and C7 spinous processes in patients with CSM maintained satisfactory long-term neurologic improvement with significantly reduced frequencies of prolonged postoperative axial neck pain and loss of C2-7 angle after surgery.

Since laminoplasty was first introduced, several techniques have been developed to reduce postoperative neck pain and progressive kyphosis following this procedure. We describe the importance of deep muscle preservation to prevent postoperative neck pain following cervical posterior surgery, using the inter-muscular plane. We performed cervical laminoplasty on 10 patients from March to July 2012. The mean follow-up duration was 14.6 (range 12-18) months, and the mean age was 58.8 (48-68) years. There were eight men and two women in the study cohort, which consisted of eight cases of cervical spondylotic myelopathy and two cases of ossification of the posterior longitudinal ligament. The Japanese Orthopaedic Association (JOA) score and neck disability index (NDI) score were assessed before and at 6 and 12 months after surgery. The numeric rating scale (NRS) for neck pain was evaluated at 1, 3, 6, and 12 months after surgery. CT scan was performed immediately after the operation, and a radiograph was performed preoperatively and during the follow-up evaluation at 1, 3, 6, and 12 months after surgery. The preoperative JOA and NDI scores improved in all patients. Although there were two patients who complained of moderate postoperative neck pain (NRS 4 and 5), their condition gradually improved. Seven patients had mild or no neck pain (below NRS 3) at the 12 month follow-up. In addition, the cervical alignment was well maintained in all but one patient. Although larger prospective cohorts, longer follow-up periods, and comparative analyses are still needed, the clinical and radiological outcomes observed in the short 12 month period in this small cohort are promising.

Retrospective analysis of prospective data. The aim of this study was to reveal baseline predictors of persistent postlaminoplasty neck pain. Axial neck pain is one of the most common complications after cervical laminoplasty; however, baseline predictors of persistent postlaminoplasty neck pain are unclear. We analyzed data from 156 patients who completed a 2-year follow-up after double-door laminoplasty for degenerative cervical myelopathy. Patients rated the average intensity of axial neck pain in the last month using an 11-point numerical rating scale preoperatively and at the 2-year follow-up. The dependent variable was the presence of moderate-to-severe neck pain (numerical rating scale ≥4) at the 2-year follow-up. The independent variables included patient characteristics, baseline radiological parameters, surgical variables, baseline axial neck pain intensity, and baseline functions, which were measured by the Japanese Orthopaedic Association score and the Short Form-36 survey (SF-36). Logistic regression analysis was performed to identify independent predictors of moderate-to-severe neck pain after laminoplasty. At the 2-year follow-up, 51 patients (32%) had moderate-to-severe neck pain, and 106 patients (68%) had no or mild pain. Univariate analysis revealed that the ratio of cervical anterolisthesis, ratio of current smoking, baseline neck pain intensity, and baseline SF-36 Mental Component Summary differed significantly between the groups. Multivariate logistic regression analysis showed that independent predictors of moderate-to-severe neck pain at the 2-year follow-up include the presence of anterolisthesis, current smoking, moderate-to-severe baseline neck pain, and lower SF-36 Mental Component Summary. The presence of anterolisthesis and moderate-to-severe baseline neck pain were also associated with significantly poorer physical function after surgery. The presence of anterolisthesis was associated not only with the highest odds ratio of

There are little data on the effects of plated, or plate-only, open-door laminoplasty on cervical range of motion (ROM), neck pain, and clinical outcomes. The purpose of this study was to compare ROM after a plated laminoplasty in patients with ossification of posterior longitudinal ligament (OPLL) versus those with cervical spondylotic myelopathy (CSM) and to correlate ROM with postoperative neck pain and neurological outcomes. The authors retrospectively compared patients with a diagnosis of cervical stenosis due to either OPLL or CSM who had been treated with plated laminoplasty in the period from 2007 to 2012 at the University of California, San Francisco. Clinical outcomes were measured using the modified Japanese Orthopaedic Association (mJOA) scale and neck visual analog scale (VAS). Radiographic outcomes included assessment of changes in the C2-7 Cobb angle at flexion and extension, ROM at C2-7, and ROM of proximal and distal segments adjacent to the plated lamina. Sixty patients (40 men and 20 women) with an average age of 63.1 ± 10.9 years were included in the study. Forty-one patients had degenerative CSM and 19 patients had OPLL. The mean follow-up period was 20.9 ± 13.1 months. The mean mJOA score significantly improved in both the CSM and the OPLL groups (12.8 to 14.5, p cervical ROM, especially in the extension angle. Among patients who have undergone laminoplasty, those with OPLL lose more ROM than do those with CSM. No correlation was observed between neck pain and ROM in either group. Neither group had a change in neck pain that reached the MCID following laminoplasty. Both groups improved in neurological function and outcomes.

This is prospective observational study. To prospectively investigate the correlation among axial neck pain; a newly developed patient-based quality of life outcome measure, the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ); and cervical sagittal alignment after open-door laminoplasty for cervical myelopathy. Many studies have focused on postoperative axial neck pain after laminoplasty. However, the correlation among cervical sagittal alignment, neck pain, and JOACMEQ has not been investigated. In total, 57 consecutive patients treated by open-door laminoplasty for cervical myelopathy were included (mean age, 63.7 y; 15 women and 42 men) and divided into 2 groups according to diagnosis [cervical spondylotic myelopathy (CSM) group: 35 patients, and ossification of the posterior longitudinal ligament (OPLL) group: 22 patients]. JOA score, a subdomain of cervical spine function (CSF) in the JOACMEQ, and the visual analog scale for axial neck pain were assessed preoperatively and 12 months postoperatively. Radiographic cervical sagittal parameters were measured by C2 sagittal vertical axis (C2 SVA), C2-C7 lordosis, C7 sagittal slope (C7 slope), and range of motion. C2 SVA values in both groups shifted slightly anteriorly between preoperative and 12-month postoperative measurements (CSM: +19.7±10.9 mm; OPLL: +22.1±13.4 mm vs. CSM: +23.2±16.1 mm; OPLL: +28.7±15.4 mm, respectively). Postoperative axial neck pain in the OPLL group showed strong negative correlations with C2 SVA and C7 slope. Strong negative correlations were found between axial neck pain and CSF in both the preoperative CSM and OPLL groups (CSM: r=-0.45, P=0.01; OPLL: r=-0.61, Ppain and CSF in the postoperative OPLL group (r=-0.51, P=0.05). This study demonstrated a significant negative correlation between neck pain and CSF in both the CSM and OPLL groups preoperatively and in the OPLL group postoperatively.

2013-01-01
2013: the year that CERN opens its doors to the public. 2013 is also the approximate number of volunteers needed to ensure that these Open Days (JPO) go ahead smoothly. Whatever your personnel status and function, you, the volunteers, are the key without which the Laboratory’s doors could not really open. Sign up now! 1,500 of you volunteered for the LHC2008 open days to mark the inauguration of the LHC. This year, with roughly 20% more visitors expected across the CERN sites over the two days, the organisers envisage closer to 2,000 volunteers. “We will be holding a wide variety of activities across the Laboratory’s various sites,” explains Virginie Blondeau, the member of the Open Days organising team in charge of recruiting and training volunteers. “As well as guides for the experiments, we will also need volunteers to welcome and direct visitors, to help with logistics and to man the sales points, etc.” The volunteers will rec...
Laminoplasty Techniques for the Treatment of Multilevel Cervical Stenosis
Directory of Open Access Journals (Sweden)
Lance K. Mitsunaga
2012-01-01
Full Text Available Laminoplasty is one surgical option for cervical spondylotic myelopathy. It was developed to avoid the significant risk of complications associated with alternative surgical options such as anterior decompression and fusion and laminectomy with or without posterior fusion. Various laminoplasty techniques have been described. All of these variations are designed to reposition the laminae and expand the spinal canal while retaining the dorsal elements to protect the dura from scar formation and to preserve postoperative cervical stability and alignment. With the right surgical indications, reliable results can be expected with laminoplasty in treating patients with multilevel cervical myelopathy.

Ombuds’ corner: Open door and confidentiality
Vincent Vuillemin
2013-01-01
For the Open Days, CERN will be transparent for all visitors. It's also the occasion to remember that the Ombuds' door is fully open every day of the year for all persons working for or on behalf of CERN. The door is open, but as soon as it's closed for a discussion, the office becomes a place where total confidentiality is preserved. This may appear as a contradiction, no? The Ombuds is available to help everyone in all circumstances, but his clause of confidentiality prevents him from acting without the consent of his “visitors”. How can he possibly resolve the in-house conflicts in groups, or units, if all the parties do not voluntarily participate in its resolution? The answer is clear: the job of the Ombuds is to help the parties resolve their conflict by themselves. He will provide a few rules of communication, a process of mutual respect, suggest some possibilities that the parties may want to follow, and mediate the dispute so that people...

Full Text Available ABSTRACT Objective: To report two cases of multilevel cervical spondylotic myelopathy with monosegmental instability, in which we performed a minimally invasive microsurgical transmuscular approach with tubular retractors to create a single-door plate laminoplasty combined with fixation of the unstable segment with lateral mass screws. Methods: The surgical procedures were performed by the senior author. In both patients, the follow-up was performed using the Oswestry Disability Index (ODI, the Visual Analogue Scale for neck and radicular pain (radVAS, neckVAS, the Neck Disability Index (NDI and the Short Form 36 (SF-36, in the preoperative (preop and postoperative (postop periods, and at 1, 3, 6, 12, 18 and 24 months. A radiological evaluation also was performed, which included AP, lateral and flexion-extension films at 6, 12 and 24 months and CT-scan at 12 months. Results: Case 1 - preop ODI: 40%, 24 months postop ODI: 4%; preop radVAS: 7, 24 months radVAS: 0; preop neckVAS: 8, postop 24 months neckVAS: 0; preopNDI: 43%, 24 months PostopNDI: 8%; SF-36 - preop Physical Functioning (PF: 40, preop Vitality (VT: 40, preop Emotional role functioning (RE: 33.3, Bodily pain (BP: 51, General Health (GH: 57, Social Functioning (SF: 75; postop PF: 95, VT: 95, RE: 100, BP: 74, GH: 87, SF: 100. Case 2 - preopODI: 46%, 24 months postopODI: 10%; preop radVAS: 7, 24m radVAS: 0; preop neckVAS: 9, postop 24 months neckVAS: 0; preopNDI: 56%, 24 months PostopNDI: 15%; SF-36 - preop PF: 39, VT: 45, RE: 33.3, BP: 50, GH: 49, SF: 70; postop PF: 90, VT: 100, RE: 100, BP: 82, GH: 87, SF: 100. No complications, cervical instability or signs of failed surgery were found trough and at final follow-up at 24 months. We found significant clinical improvement in both patients. Conclusions: Minimally invasive cervical laminoplasty combined with lateral mass screw fixation for the unstable segment is a useful technique in cases with multilevel cervical spondylotic myelopathy
Novel Door-opening Method for Six-legged Robots Based on Only Force Sensing
Chen, Zhi-Jun; Gao, Feng; Pan, Yang
2017-09-01
Current door-opening methods are mainly developed on tracked, wheeled and biped robots by applying multi-DOF manipulators and vision systems. However, door-opening methods for six-legged robots are seldom studied, especially using 0-DOF tools to operate and only force sensing to detect. A novel door-opening method for six-legged robots is developed and implemented to the six-parallel-legged robot. The kinematic model of the six-parallel-legged robot is established and the model of measuring the positional relationship between the robot and the door is proposed. The measurement model is completely based on only force sensing. The real-time trajectory planning method and the control strategy are designed. The trajectory planning method allows the maximum angle between the sagittal axis of the robot body and the normal line of the door plane to be 45º. A 0-DOF tool mounted to the robot body is applied to operate. By integrating with the body, the tool has 6 DOFs and enough workspace to operate. The loose grasp achieved by the tool helps release the inner force in the tool. Experiments are carried out to validate the method. The results show that the method is effective and robust in opening doors wider than 1 m. This paper proposes a novel door-opening method for six-legged robots, which notably uses a 0-DOF tool and only force sensing to detect and open the door.
[Psychiatry with open doors. Part 1: Rational for an open door for acute psychiatry].
Sollberger, D; Lang, U E
2014-03-01
Despite the reform efforts of the last decades modern acute psychiatry still stands between conflicting priorities in everyday practice. The protection of patient autonomy might conflict with a regulatory mandate of psychiatry in societal contexts and the necessity of coercive measures and involuntary treatment might become problematic with respect to presumed but contentious interests of the patient. The conflicts particularly concern questions of involuntary commitment, door closing, coercive and isolation measures. Research on the topic of therapeutic effectiveness of these practices is rare. Accordingly, the practice depends on the federal state, hospital and ward and is very heterogeneous. Epidemiological prognosis predicts an increase of psychiatric disorders; however, simultaneously in terms of medical ethics the warranty of patient autonomy, shared decision-making and informed consent in psychiatry become increasingly more important. This challenges structural and practical changes in psychiatry, particularly in situations of self and third party endangerment which are outlined and a rationale for an opening of the doors in acute psychiatric wards is provided.
Effect of door opening and defrost cycle on a freezer with phase change panels
International Nuclear Information System (INIS)
Gin, B.; Farid, M.M.; Bansal, P.K.
2010-01-01
An investigation into the effectiveness of phase change material (PCM) panels placed against the internal walls of a freezer to maintain stable temperatures in the presence of heat loads such as door openings, defrosting, and loss of electrical power was carried out. Temperature response was studied during loss of power, a defrost cycle lasting 30 min, and a door opening scheme of 13 door openings over an 11 h period. This PCM system has significantly decreased the rate of temperature increase inside the freezer during defrosting and power loss. Energy consumption was measured during steady operation, a defrost cycle of 30 min, and a scheme of eight door openings at 40 min intervals. It was found that heat loads caused greater energy consumption, and that the presence of PCM during defrosting and door openings resulted in slightly lower energy consumption compared to without PCM.

Régine Chareyron (on the right), who has worked for the Visits Service for 35 years, is pictured here with Chantal Montuel and Cora Roth. CERN inaugurated its permanent visitor centre "Microcosm" in 1989. This brand new outreach facility added a crowning touch to CERN's tradition of openness in conducting its research activities. In keeping with Article II of the Convention, which stipulates that "the results of its (...) work shall be published or otherwise made available," CERN was already organising visits for the general public in the late 1950s, with members of the personnel doubling up as voluntary tour guides. By 1959, the Laboratory was opening its doors to almost 2 500 visitors a year. Ten years down the line, that number had risen to 12 700, and today CERN welcomes some 30 000 visitors through its doors every year. In addition, the Visits Service has developed teaching packs for sc...
Open-ended and Open-door Treatment Groups for Young People with Mental Illness.
Miller, Rachel; Mason, Susan E
2012-01-01
The concept of open-ended groups is expanded to include an open-door model (OEOD) wherein members with severe mental illnesses, including schizophrenia disorders and bi-polar, can join, leave, and re-enter groups as their life circumstances dictate their availability and willingness for treatment. This model is grounded on the work of Schopler and Galinsky's (1984/2006) and Galinsky and Schopler's (1989) theses on the value and processes of open-ended groups and includes perspectives on mutual aid and group development. Groupwork with the OEOD format is illustrated with examples taken from a group of 79 participants diagnosed with first-episode schizophrenia/schizoaffective disorders, 40 of who had co-occurring substance abuse. Of the 79 participants in the OEOD group program, 70 (89%) remained in treatment for the maximum of 3 years. The over-all value of group treatment for this population is reviewed along with the small number of available publications on open-ended and open-door-type groups.

Prospective study. To investigate the efficacy of transcranial electrically stimulated muscle-evoked potentials (TcE-MsEPs) for predicting postoperative segmental upper extremity palsy following cervical laminoplasty. Postoperative segmental upper extremity palsy, especially in the deltoid and biceps (so-called C5 palsy), is the most common complication following cervical laminoplasty. Some papers have reported that postoperative C5 palsy cannot be predicted by TcE-MsEPs, although others have reported that it can be predicted. This study included 160 consecutive cases that underwent open-door laminoplasty, and TcE-MsEP monitoring was performed in the biceps brachii, triceps brachii, abductor digiti minimi, tibialis anterior, and abductor hallucis. A >50% decrease in the wave amplitude was defined as an alarm point. According to the monitoring alarm, interventions were performed, which include steroid administration, foraminotomies, etc. Postoperative deltoid and biceps palsy occurred in 5 cases. Among the 155 cases without segmental upper extremity palsy, there were no monitoring alarms. Among the 5 deltoid and biceps palsy cases, 3 had significant wave amplitude decreases in the biceps during surgery, and palsy occurred when the patients awoke from anesthesia (acute type). In the other 2 cases in which the palsy occurred 2 days after the operation (delayed type), there were no significant wave decreases. In all of the cases, the palsy was completely resolved within 6 months. The majority of C5 palsies have been reported to occur several days after surgery, but some of them have been reported to occur immediately after surgery. Our results demonstrated that TcE-MsEPs can predict the acute type, whereas the delayed type cannot be predicted. A >50% wave amplitude decrease in the biceps is useful to predict acute-type segmental upper extremity palsy. Further examination about the interventions for monitoring alarm will be essential for preventing palsy.

The role of the operating room (OR) environment has been thought to contribute to surgical site infection rates. The quality of OR air, disruption of airflow, and other factors may increase contamination risks. We measured air particulate counts (APCs) to determine if they increased in relation to traffic, door opening, and other common activities. During 1 week, we recorded APCs in 5-minute intervals and movement of health care workers. Trained observers recorded information about traffic, door openings, job title of the opener, and the reason for opening. At least 1 OR door was open during 47% of all readings. There were 13.4 door openings per hour during cases. Door opening rates ranged from 0.19-0.28 per minute. During this time, a total of 660 air measurements were obtained. The mean APCs were 9,238 particles (95% confidence interval [CI], 5,494- 12,982) at baseline and 14,292 particles (95% CI, 12,382-16,201) during surgery. Overall APCs increased 13% when either door was opened (P opening. We observed numerous instances of verbal communication and equipment movement. Improving efficiency of communication and equipment can aid in reduction of traffic. Further study is needed to examine links between microbiologic sampling, outcome data, and particulate matter to enable study of risk factors and effects of personnel movement.

Three special days and one public open day: at the end of September our Laboratory will open its doors to visitors from CERN, the local region and all over the world. With over 150,000 visitors expected in total, the organisation of the OpenDays is a challenge that a core team of eleven people have taken up with enthusiasm. They come from several departments but share one goal: making the last four days of September an unforgettable experience for all the visitors who will come to discover the Laboratory and its scientists. The core team in charge of the organisation of the events is co-ordinated by Hermann Schmickler. “The events are an opportunity for us to celebrate the discoveries, the excellent performance of the technical installations and the vital contribution of all the CERN personnel, the thousands of users and those working under support contracts,” says Hermann Schmickler.

To determine whether radiological, clinical, and demographic findings in patients with cervical spondylotic myelopathy (CSM) were independently associated with loss of cervical lordosis (LCL) after laminoplasty. The prospective study included 41 consecutive patients who underwent laminoplasty for CSM. The difference in C2-7 Cobb angle between the postoperative and preoperative films was used to evaluate change in cervical alignment. Age, sex, body mass index (BMI), smoking history, preoperative C2-7 Cobb angle, T1 slope, C2-7 range of motion (C2-7 ROM), C2-7 sagittal vertical axis (C2-7 SVA), and cephalad vertebral level undergoing laminoplasty (CVLL) were assessed. Data were analyzed using Pearson and Spearman correlation test, and univariate and stepwise multivariate linear regression. T1 slope, C2-7 SVA, and CVLL significantly correlated with LCL (P < 0.001), whereas age, BMI, and preoperative C2-7 Cobb angle did not. In multiple linear regression analysis, higher T1 slope (B = 0.351, P = 0.037), greater C2-7 SVA (B = 0.393, P < 0.001), and starting laminoplasty at C4 level (B = - 7.038, P < 0.001) were significantly associated with higher postoperative LCL. Cervical alignment was compromised after laminoplasty in patients with CSM, and the degree of LCL was associated with preoperative T1 slope, C2-7 SVA, and CVLL.

In search of a credible and cost-effective way to promote Mount Sinai Hospital (Mount Sinai) and educate a broad public, Mount Sinai opened its doors wide to The Globe and Mail (The Globe). The result was a three-part national feature series that told Mount Sinai's compelling story, provided third-party credibility and confirmed the value of proactive media relations. The series engaged our staff, energized our volunteers and reached both stakeholders and the general public on an emotional level. It also generated the more than dollars 6 million worth of equivalent advertising space it would have required for Mount Sinai to reach this national audience.

Early surgical education is required for neurosurgical residents to learn many surgical procedures. However, the participation of less experienced residents may increase perioperative complication rates. Perioperative complication studies in the field of neurosurgery are being increasingly published; however, studies have not yet focused on cervical laminoplasty. The study population included 193 consecutive patients who underwent cervical laminoplasty in Tokyo Metropolitan Neurological Hospital between 2008 and 2014. Patient and surgeon background factors, as well as perioperative complication rates were retrospectively compared between resident and board-certified spine neurosurgeon groups. Deteriorated or newly developed neurological deficits and surgical site complications within 30days of cervical laminoplasty were defined as perioperative complications. Out of 193 patients, 123 (64%) were operated on by residents as the first operator and 70 (36%) by board-certified spine neurosurgeons. No significant differences were observed in patient and surgeon factors between the two groups, except for hyperlipidemia (13 vs 17, p=0.02). Furthermore, no significant differences were noted in perioperative complication rates between the two groups (7 [5.7%] vs 4 [5.7%], p=1). Cervical laminoplasty performed in a standardized manner by residents who received their surgical training in our hospital did not increase perioperative complication rates, and ensured the safety of patients.

A gas dynamic laser is shown wherein gases containing constituents necessary to obtain a lasing action are passed through a nozzle array and directed into a lasing cavity and through a diffuser to an exit. An opening is located on each side of said lasing cavity with a shutter box outside of said cavity having a shutter door for opening or closing said opening. A mirror box is located behind each shutter box and contains a mirror. These mirrors are aligned with the openings in the lasing cavity with each door positioned between an opening and a mirror. Another outlet opening is positioned downstream of the first opening which provides an outlet opening for a laser beam. A shutter box is located around this opening and also houses a shutter door for opening and closing said opening. The mirror box which extends behind this shutter box includes opening means for permitting the output beam to pass through an aerodynamic window to atmosphere. Actuating means are provided for rapidly opening and closing said shutter doors. Bearing means including recirculating balls are located on the top and bottom of each shutter door to ride in tracks at an angle to the sealing surface on the laser device. Vacuum means are provided to reduce the pressure in the shutter box and mirror box independently of the pressure in the lasing cavity
Globalization: an open door for the knowledge economy

Full Text Available Globalization refers to an emphasized process of global integration and spreading a set of ideas related to the economical activity and goods’ production, the premises being the liberalization of international commerce and the capital flows, the speeding up of the technological progress and informational society. The cognitive society is more and more obvious and unanimously accepted, which actually proves its efficiency. If traditional, conservative communities, which are not open to change and reject from the start anything new on the horizon, still exist today, they are isolated cases that will eventually be "converted" by this wave of information that has become indispensable to any development because in its absence resources could not be used efficiently. Taking into consideration these elements, this paper wishes to give arguments to the fact that globalization can be seen as being an open door for the cognitive society.

LRO-LAMP failsafe door-open performance: improving FUV measurements of dayside lunar hydration
Davis, Michael W.; Greathouse, Thomas K.; Kaufmann, David E.; Retherford, Kurt D.; Versteeg, Maarten H.
2017-08-01
The Lunar Reconnaissance Orbiter's (LRO) Lyman Alpha Mapping Project (LAMP) is a lightweight (6.1 kg), lowpower (4.5 W), ultraviolet spectrograph based on the Alice instruments aboard the European Space Agency's Rosetta spacecraft and NASA's New Horizons spacecraft. Its primary job is to identify and localize exposed water frost in permanently shadowed regions (PSRs) near the Moon's poles, and to characterize landforms and albedos in PSRs. LRO launched on June 18, 2009 and reached lunar orbit four days later. LAMP operated with its failsafe door closed for its first seven years in flight. The failsafe door was opened in October 2016 to increase light throughput during dayside operations at the expense of no longer having the capacity to take further dark observations and slightly more operational complexity to avoid saturating the instrument. This one-time irreversible operation was approved after extensive review, and was conducted flawlessly. The increased throughput allows measurement of dayside hydration in one orbit, instead of averaging multiple orbits together to reach enough signal-to-noise. The new measurement mode allows greater time resolution of dayside water migration for improved investigations into the source and loss processes on the lunar surface. LAMP performance and optical characteristics after the failsafe door opening are described herein, including the new effective area, wavelength solution, and resolution.

The door to China`s vast market for power generation was opened a bit further for foreign firms in November. That is when power ministry head Shi Dazhen said the country would rely on overseas investors for 20 percent of the funding needed to boost output--double the amount foreigners were previously allowed to contribute. Through 1995, foreigners invested $12.2 billion in China`s electricity industry, accounting for 10 percent of total investment. According to Shi, foreign investors will be asked to provide about $17 billion of the $84 billion China plans to invest in the sector over the next five years. Under China`s Ninth Five-Year Plan (1996-2000), the government aims to boost the country`s power generation capacity at the rate of 15,000 MW to 20,000 MW annually by the year 2000. Since China`s public external debt balance already exceeds $80 billion, however, the government would seem to have little choice but to allow foreigners a greater role. Shi also said that foreigners would be allowed 100 percent ownership of PRC power projects. This is discouraged under China`s current industry guidelines. It is, however, expected to be permitted under China`s first build-operate-transfer (BOT) law, which was anticipated by the end of 1996, says Susan Urkevich, director of project finance at HSBC Investment Bank Asia in Hong Kong. Indeed, China`s first BOT is already happening.
Numerical modeling of cold room's hinged door opening and closing processes
Carneiro, R.; Gaspar, P. D.; Silva, P. D.; Domingues, L. C.
2016-06-01
The need of rationalize energy consumption in agrifood industry has fasten the development of methodologies to improve the thermal and energy performances of cold rooms. This paper presents a three-dimensional (3D) transient Computational Fluid Dynamics (CFD) modelling of a cold room to evaluate the air infiltration rate through hinged doors. A species transport model is used for modelling the tracer gas concentration decay technique. Numerical predictions indicate that air temperature difference between spaces affects the air infiltration. For this case study, the infiltration rate increases 0.016 m3 s-1 per K of air temperature difference. The knowledge about the evolution of air infiltration during door opening/closing times allows to draw some conclusions about its influence on the air conditions inside the cold room, as well as to suggest best practices and simple technical improvements that can minimize air infiltration, and consequently improve thermal performance and energy consumption rationalization.

Highlights: • Heat release rate of electrical cabinet fire source in a vitiated atmosphere. • Experimental database for proper validation the combustible modelling, taking into account the oxygen depletion in an enclosure. • New model for complex fire source. - Abstract: The study of electrical fires is a major concern for fire safety in the industry and more particularly for fire safety in nuclear facilities. To investigate this topic, IRSN conducted a large number of real-scale experiments involving open-door electrical cabinets burning firstly under a calorimetric hood and then inside a mechanically-ventilated compartment. The main challenges are to determine accurately the heat release rate of such a complex fire source in a vitiated atmosphere and to provide an experimental database for validating properly the combustible modelling, taking into account the oxygen depletion in an enclosure. After providing a detailed description of the fire scenarios and of the experimental apparatus, this paper focuses on the characteristic stages of the cabinet fire development, essentially based on the heat release rate time evolution of the fire. The effects of the confinement, of the outlet branch location, of the ventilation management and of the fire barrier on the fire source were then investigated. The reproducibility of electrical cabinet fires is also studied. A new model for complex fire source (applied in this study for open-door electrical cabinet fires) was then developed. This model was introduced in the zone code SYLVIA and the major features of the compartment fire experiments, such as characteristic heat release rate with effect of oxygen depletion and over-pressure peak were then calculated with a rather good agreement for this complex fire source (i.e. electrical cabinet)

There has been a continuity in French energy policy for several decades now - the aim to guarantee a supply of energy under reliable, economical conditions. The review, which the International Energy Agency has just conducted, notes how successful this policy has been. But it also emphasizes the need for France to open the doors of this market to the rest of Europe. (authors)
Motor actuated vacuum door. [for photography from sounding rockets
Hanagud, A. V.
1986-01-01
Doors that allow scientific instruments to record and retrieve the observed data are often required to be designed and installed as a part of sounding rocket hardware. The motor-actuated vacuum door was designed to maintain a medium vacuum of the order of 0.0001 torr or better while closed, and to provide an opening 15 inches long x 8.5 inches wide while open for cameras to image Halley's comet. When the electric motor receives the instruction to open the door through the payload battery, timer, and relay circuit, the first operation is to unlock the door. After unlatching, the torque transmitted by the motor to the main shaft through the links opens the door. A microswitch actuator, which rides on the linear motion conversion mechanism, is adjusted to trip the limit switch at the end of the travel. The process is repeated in the reverse order to close the door. 'O' rings are designed to maintain the seal. Door mechanisms similar to the one described have flown on Aerobee 17.018 and Black Brant 27.047 payloads.
Close-fitting shield doors with sculptured edges

Goodman, L.
1986-01-01
The US Department of Energy has contracted with Fluor Technology, Inc. for design and engineering of a facility to begin reprocessing fuel from the reactors at Hanford, Washington. Within the facility, a 15-cm (6-in.)-thick, steel shield door is needed to close an opening 4.3 m (14 ft) high x 8.2 m (27 ft) wide. Two cranes and a centrally located monorail hoist must pass through the opening. The door weighs about 41,000 kg (45 ton), and passage of the hoist will be the most frequent cause for opening the door. These two factors essentially mandated a three-piece door, which allows for using commercially available chain hoists to raise and lower the individual door sections. Normally, there is a 187-Pa (0.75-in. water gauge) pressure differential across the door, and minimal air leakage is essential. Stepped, mating edges between sections and along the adjacent concrete structures are typical with such doors, but so are significant gaps (and air leaks) around the edges. Gaps are needed to preclude frictional jamming between edges as a section is lowered. The challenge was to conceive a method to produce near-zero gaps and preclude jamming without involving impractically tight tolerances. The chosen method was to place trapezoidally shaped, steel gaskets on the door-section edges and on the mating concrete surfaces. The concept is described

In fusion experimental reactors, the in-vessel components such as blanket are activated due to D-T operation and they have to be assembled and replaced by remote operation through port penetration of plasma vacuum vessel. A double seal door is inevitably required at an interface between vacuum vessel port and maintenance cask in order to avoid the dispersion of tritium and activated dust during in-vessel component handling. The double seal door should have two open/close doors with four seal surfaces so as to keep leak tightness both of the vacuum vessel and the maintenance cask when doors closed, and to provide access space for handling in-vessel components when doors opened. A prototype compact double seal door with an attractive kinematics of parabolic trajectory has been proposed so as to minimize dead space for the door open/close operation, compared with ordinary slide or hinge type door. Based on this design concept, a sub-scaled model of double seal door with trapezoidal cross-section of around 0.2 m 2 has been fabricated. Through the preliminary experiments such as open/close performance, the double seal door mechanism with parabolic trajectory has been successfully demonstrated. As for leak tightness, seal characteristics of a polyimide ring irradiated up to 10 MGy have been measured. (author)

Failure case of a garage door opener
Directory of Open Access Journals (Sweden)
Habib, K.
2005-12-01
Full Text Available A failure analysis of a garage door opener was conducted for determination of the cause of the failure. The analysis included visual inspections of broken parts as well as electron microscopy examinations of the fracture surface. The visual inspections showed that a bolt connected to the inner trolley of the garage opener assembly was initially fractured. Also, the results of electron microscopy examinations revealed that the broken bolt failed by fatigue damage phenomenon, due to alternating torsional stresses throughout 25 years of an operational life of the garage opener. In addition, a mathematical model corresponding to the failure mechanism was derived along the failure analysis. The model comprises of both design philosophy and fracture mechanics approaches.
Se analizó el fallo del mecanismo de apertura de una puerta de garaje con el fin de determinar sus causas. El análisis incluyó una inspección visual de las piezas rotas así como un examen mediante microscopía de la superficie de fractura. La inspección visual reveló que primero se fracturó un perno conectado al carro interior del mecanismo de apertura. Los resultados del análisis por microscopía electrónica también mostraron que el perno roto falló debido a fenómenos de daño por fatiga, debido a los esfuerzos torsionales alternos a la largo de 25 años de vida en servicio del mecanismo de apertura. Por otra parte, se construyó un modelo matemático correspondiente al mecanismo de rotura durante el análisis del mismo. Este modelo comprende enfoques, tanto de la filosofía de diseño como de la mecánica de fractura.

Retrofit curtain for overhead doors
Energy Technology Data Exchange (ETDEWEB)
Leckie, R E
1987-12-29
A heat insulating curtain has been developed for reducing heat losses through overhead doors of the type commonly found in industrial warehouses. The curtain consists of a reinforced polyester fabric attached to the outside top of the overhead door and moves with the door as it opens and closes. A T-shaped edge track seals the edges of the curtain to the door frame; the edge of the curtain is also T-shaped and runs up and down the track as the curtain is raised and lowered. The curtain fabric is ultraviolet resistant, durable, flexible, and transparent, and transforms the door into a solar collector which provides solar heated air to the building interior. Two curtains have been satisfactorily installed and tested at a warehouse in Calgary, Alberta. A market evaluation study was conducted to determine the possible buyers for such a door curtain. A target market consisting of those wishing to fix old, leaky doors was selected and a marketing strategy developed. The described strategy includes product development, pricing, distribution, promotion, and advertising. 2 figs., 1 tab.

The Autonomous Urban Reconnaissance Ingress System (AURIS™) addresses a significant limitation of current military and first responder robotics technology: the inability of reconnaissance robots to open doors. Leveraging user testing as a baseline, the program has derived specifications necessary for military personnel to open doors with fielded UGVs (Unmanned Ground Vehicles), and evaluates the technology's impact on operational mission areas: duration, timing, and user patience in developing a tactically relevant, safe, and effective system. Funding is provided through the US ARMY Tank Automotive Research, Development and Engineering Center (TARDEC) and the project represents a leap forward in perception, autonomy, robotic implements, and coordinated payload operation in UGVs. This paper describes high level details of specification generation, status of the last phase of development, an advanced view of the system autonomy capability, and a short look ahead towards the ongoing work on this compelling and important technology.

Across the PS complex - from Linac 2 to TT2 to the accelerator itself - teams have seen the closing of their retro-1980s entryways, and the opening of state-of-the-art access points in compliance with the highest nuclear safety standards. One of the new PS access points. The new PS access system provides more than just doors. Designed to protect against the radiation hazards and other risks caused by machine operation, the access system will monitor who goes into each zone, check whether or not the individual has the appropriate permissions to be entering, and even stop the beam if access is attempted during beam mode. "These new points provide automatic means to check that the right people are going in and in safe circumstances," says Pierre Ninin, project leader of the PS complex safety system. "All of these checks were previously done manually, so the burden on operators has been significantly reduced." The 19 new access points were successfully insta...

In this study the authors investigated the neck pain of patients with cervical myelopathy by using a visual analog scale (VAS) before and after laminoplasty, and they analyzed the association of amount of neck pain with the clinical results. A retrospective review was conducted in 41 patients with cervical myelopathy who underwent cervical laminoplasty. The patients were assessed using questionnaires to evaluate the neck pain intensity before surgery, and 2 years after surgery, the outcome was assessed using a VAS. The degree of cervical lordosis and range of motion (ROM) of the cervical spine were evaluated before and after laminoplasty. The neurological status was also evaluated before and after surgery. The patients were classified into 2 groups according to their preoperative neck pain: 1) the pain (PA) group, which included patients whose preoperative VAS score was more than 1 mm; and 2) the no pain (NP) group, which included patients whose preoperative VAS score was 0 mm. Inclusion in the PA group indicated a restriction of the cervical ROM before laminoplasty; however, the improvement of neck pain in this group and the deterioration of pain status in the NP group eliminated this difference after laminoplasty. Thereafter, the PA group was classified into 2 subgroups according to the improvement of the preoperative neck pain: 1) the improved group, which included patients whose postoperative VAS score decreased; and 2) the no improvement group, which included patients who were not in the improved group. No significant differences were observed in the average recovery and radiographic results between these 2 subgroups. Neck pain before surgery in the PA group indicated a restriction of the cervical ROM; however, the improvement of neck pain in this group and the deterioration of pain status in the NP group indicated the disappearance of this difference postoperatively. Moreover, improvement of preoperative neck pain was not associated with the radiographic

Psychiatry opens to the world at a time when the very basis of psychiatric practice, namely the asylum, is called into question. Studies appear in Quebec and Canadian journals concurrent to the introduction of new formulas for care, such as the delivery of psychiatric services in general hospitals and clinics, that allow patients to be treated outside the walls of psychiatric hospitals. In addition, postwar psychiatry takes an optimistic view toward the future of children with impairments through the creation of specialized schools and workshops. From the mid-20th century onward, the thinking in psychiatry centres on the open door.
Modeling and Simulation of Two Wheelchair Accessories for Pushing Doors.

2017-03-27
Independent mobility is vital to individuals of all ages, and wheelchairs have proven to be great personal mobility devices. The tasks of opening and navigating through a door are trivial for healthy people, while the same tasks could be difficult for some wheelchair users. A wide range of intelligent wheelchair controllers and systems, robotic arms, or manipulator attachments integrated with wheelchairs have been developed for various applications, including manipulating door knobs. Unfortunately, the intelligent wheelchairs and robotic attachments are not widely available as commercial products. Therefore, the current manuscript presents the modeling and simulation of a novel but simple technology in the form of a passive wheelchair accessory (straight, arm-like with a single wheel, and arc-shaped with multiple wheels) for pushing doors open from a wheelchair. From the simulations using different wheel shapes and sizes, it was found that the arc-shaped accessory could push open the doors faster and with almost half the required force as compared to the arm-like accessory. Also, smaller spherical wheels were found to be best in terms of reaction forces on the wheels. Prototypes based on the arc-shaped accessory design will be manufactured and evaluated for pushing doors open and dodging or gliding other obstacles.

Full Text Available The article is a preliminary to a modification concept of the sliding watertight bulkhead door used on ships and vessels. Hydraulic or electro-hydraulic drives used to move these doors require complicated and extended pressure installations with large amounts of hydraulic fluid. Well-known operational drawbacks of these installations include high level of noise and possibility of various leaks in the hydraulic system. Being the first in a series, the present article describes and analyses critical states which can take place during evacuation of people through openings in the watertight bulkhead doors on seagoing ships and vessels.

Study Design Systematic review. Objective In patients aged 18 years or older, with cervical spondylotic myelopathy or ossification of the posterior longitudinal ligament (OPLL), does sparing the C2 muscle attachments and/or C7-preserving cervical laminoplasty lead to reduced postoperative axial pain compared with conventional C3 to C7 laminoplasty? Do these results vary based on early active postoperative cervical motion? Methods A systematic review of the English-language literature was undertaken for articles published between 1970 and August 17, 2012. Electronic databases and reference lists of key articles were searched to identify studies evaluating C2/C3- or C7-preserving cervical laminoplasty for the treatment of cervical spondylotic myelopathy (CSM) or OPLL in adults. Studies involving traumatic onset, cervical fracture, infection, deformity, or neoplasms were excluded, as were noncomparative studies. Two independent reviewers assessed the level of evidence quality using the grading of recommendations assessment, development and evaluation (GRADE) system, and disagreements were resolved by consensus. Results We identified 11 articles meeting our inclusion criteria. Only the randomized controlled trial (RCT) showed no significant difference in late axial pain (at 12 months) when C7 spinous muscle preservation was compared with no preservation. However, seven other retrospective cohort studies showed significant pain relief in the preserved group compared with the nonpreserved group. The preservation group included those with preservation of the C7 spinous process and/or attached muscles, the deep extensor muscles, or C2 muscle attachment and/or C3 laminectomy (as opposed to laminoplasty). One study that included preservation of either the C2 or C7 posterior paraspinal muscles found that only preservation of the muscles attached to C2 resulted in reduced postoperative pain. Another study that included preservation of either the C7 spinous process or

Dr. Charlton used diverse approaches to identify research institutions which provided home to outstanding scientists and work. One intriguing example of long-lasting scientific excellence is Cambridge with 19 Nobel laureates who worked at the University or at the MRC Molecular Biology Unit when they received the prize between 1947 and 2006. With specific reference to Cambridge, I would like to complement the primarily quantitative assessment and offer considerations as to why and how research achievements may have clustered in space and time. Indeed, observations voiced by the mathematician Richard Hamming as to how great research can be pursued offer explanations for the series of great science in the UK. In my view, the most important determinant of the clustering may be illustrated by Hamming's fitting picture of "open doors": working in environments with the doors open allows constant interactions with peers with various disciplinary backgrounds, and thus fast avoidance of detours or dead ends in science and, ultimately, a focus on and the solution of problems of paramount, rather than of tangential, importance. Narrative insights into a strong argumentative tradition at Cambridge provided by Drs. Watson and Magueijo between 1968 and 2003 are in line with Hamming's suggestion and the value of group creativity. In the internet age with abundant interactions beyond home institutions we should not be surprised if clusters of great science were no longer confined to the usual suspect institutions which were awarded disproportionally with Nobel prizes in the past.
Development, Control, and Evaluation of an Actuated Car Door.
Strolz, M; Mortl, A; Graf, M; Buss, M
2009-01-01
Actuated car doors are a promising way to increase the convenience of access to cars. We propose an advanced actuation and control concept which can easily be integrated into conventional car doors. By utilizing a linear, nonbackdrivable actuator and various sensors, both automatic and manual door operations are enabled. A discrete state controller ensures a safe operation of the door, including automatic opening and closing. The realization of a supportive, high-quality haptic interaction with the car door for the manual operation is the principal part of our work. Due to the impracticality of a direct measurement of the user interaction force at a car door, we chose impedance control to render the desired dynamics. The impedance was designed to provide a convenient, intuitive, and safe manual handling of the door. We implemented and tested four different impedance control schemes, of which impedance control with actuator force feedback performed best. Two experimental evaluations with 16 and 27 participants revealed a predominant approval of the actuated car door.

Repeated hospitalizations and arrests or incarcerations diminish the ability of individuals with serious mental illnesses to pursue recovery. Community mental health systems need new models to address recidivism as well as service fragmentation, lack of engagement by local stakeholders, and poor communication between mental health providers and the police. This study examined the initial effects on institutional recidivism and measures of recovery among persons enrolled in Opening Doors to Recovery, an intensive, team-based community support program for persons with mental illness and a history of inpatient psychiatric recidivism. A randomized controlled trial of the model is underway. The number of hospitalizations, days hospitalized, and arrests (all from state administrative sources) in the year before enrollment and during the first 12 months of enrollment in the program were compared. Longitudinal trajectories of recovery-using three self-report and five clinician-rated measures-were examined. Analyses accounted for baseline symptom severity and intensity of involvement in the program. One hundred participants were enrolled, and 72 were included in the analyses. Hospitalizations decreased, from 1.9±1.6 to .6±.9 (precovery measures, and trajectories of improvement were apparent across the entire follow-up period. Opening Doors to Recovery holds promise as a new service approach for reducing hospital recidivism and promoting recovery in community mental health systems and is deserving of further controlled testing.

Most of the elevator door controllers have been controlled by DC Motors as an actuator. Recently, The control system using AC induction motor and general purpose inverter has been applied to control of elevator door. But there are some difficulties in making use of this system, such as adjustment of door speed pattern, door open-close time, and security of passenger safety. In order to solve these problems, a special inverter has been developed with an encoder feedback. From the result of field-test, we proved that a special inverter with encoder feedback device has come to considerable effect. Until now about 1,200 sets of these inverters are operated in Korea and about 100 sets are operated in South-east Asia. (author). 3 refs., 10 figs., 3 tabs.

Closed windows, open doors: geopolitics and post-1949 Mainland Chinese immigration to Canada.
Liu X-f; Norcliffe, G
1996-01-01
"Since 1949 there have been dramatic changes in the flow of migrants from Mainland China to Canada, which existing structural models of migration, emphasizing factors in the destination country, do not fully capture. Conditions in the country of origin, and geopolitical relationships between China and Canada, played a decisive role in this migration.... Changing geopolitical circumstances led China to develop an open-door policy between 1973 and 1989, leading to increasing flows of migrants to Canada. The political response in Canada to the Tiananmen Square massacre of 1989 was to allow all Chinese students and workers in Canada to stay, if they so wished.... The result was a large inflow making MCIS the third-largest group of immigrants to Canada in the early 1990s." (EXCERPT)

This thesis describes a study of shielding design techniques used for radiation therapy facilities that employ megavoltage linear accelerators. Specifically, an evaluation of the shielding design formalism described in NCRP report 151 was undertaken and a feasibility study for open-door 6 MV radiation therapy treatments in existing 6 MV, 18 MV treatment rooms at the Montreal General Hospital (MGH) was conducted. To evaluate the shielding design formalism of NCRP 151, barrier-attenuated equivalent doses were measured for several of the treatment rooms at the MGH and compared with expectations from NCRP 151 calculations. It was found that, while the insight and recommendations of NCRP 151 are very valuable, its dose predictions are not always correct. As such, the NCRP 151 methodology is best used in conjunction with physical measurements. The feasibility study for 6 MV open-door treatments made use of the NCRP 151 formalism, together with physical measurements for realistic 6 MV workloads. The results suggest that, dosimetrically, 6 MV open door treatments are feasible. A conservative estimate for the increased dose at the door arising from such treatments is 0.1 mSv, with a 1/8 occupancy factor, as recommended in NCRP 151, included.

Axial neck pain after C3-6 laminoplasty has been reported to be significantly lesser than that after C3-7 laminoplasty because of the preservation of the C-7 spinous process and the attachment of nuchal muscles such as the trapezius and rhomboideus minor, which are connected to the scapula. The C-6 spinous process is the second longest spinous process after that of C-7, and it serves as an attachment point for these muscles. The effect of preserving the C-6 spinous process and its muscular attachment, in addition to preservation of the C-7 spinous process, on the prevention of axial neck pain is not well understood. The purpose of the current study was to clarify whether preservation of the paraspinal muscles of the C-6 spinous process reduces postoperative axial neck pain compared to that after using nonpreservation techniques. The authors studied 60 patients who underwent C3-6 double-door laminoplasty for the treatment of cervical spondylotic myelopathy or cervical ossification of the posterior longitudinal ligament; the minimum follow-up period was 1 year. Twenty-five patients underwent a C-6 paraspinal muscle preservation technique, and 35 underwent a C-6 nonpreservation technique. A visual analog scale (VAS) and VAS grading (Grades I-IV) were used to assess axial neck pain 1-3 months after surgery and at the final follow-up examination. Axial neck pain was classified as being 1 of 5 types, and its location was divided into 5 areas. The potential correlation between the C-6/C-7 spinous process length ratio and axial neck pain was examined. The mean VAS scores (± SD) for axial neck pain were comparable between the C6-preservation group and the C6-nonpreservation group in both the early and late postoperative stages (4.1 ± 3.1 vs 4.0 ± 3.2 and 3.8 ± 2.9 vs 3.6 ± 3.0, respectively). The distribution of VAS grades was comparable in the 2 groups in both postoperative stages. Stiffness was the most prevalent complaint in both groups (64.0% and 54

We evaluate the association of laminar airflow (LAF) and OR traffic with intraoperative contamination rates. Two sterile basins were placed in each room during 81 cases, one inside and one outside the LAF. One Replicate Organism Detection and Counting (RODAC) plate from each basin was sent for culture at successive 30-minute intervals from incision time until wound closure. At successive 30-minute intervals more plates were contaminated outside than inside the LAF. A negative binomial model showed that the bacteria colony forming units (CFU) depended on whether there were any door openings (P=0.02) and the presence of LAF (P=0.003). LAF decreases CFU by 36.6%. LAF independently reduces the risk of contamination and microbial counts for surgeries lasting 90 minutes or less. © 2013.

OECD/NEA PRISME Fire Project is an international co-operation project to investigate fire propagation by means of experiments and analyses for nuclear power plant applications. This project focuses on the generation of experimental data for fire and smoke propagation from the fire room to adjacent rooms under various conditions and room configurations. In addition, analyses using computer codes are performed to understand the phenomena of interest and to produce a consistent interpretation of the experimental results. The PRISME Project is composed of series of tests named as SOURCE, DOOR, LEAK and Global Tests. The SOURCE is composed of tests to characterize the fire source, and the DOOR is to study fire and smoke propagation through an open door, while the LEAK is to investigate hot gas leakages through other modes of openings such as holes, a slot, a duct, and a partially opened door. The Global test will be conducted as integral tests on the basis of the results of the previous separate effects tests. In this paper, simulations are performed with FDS5 computer code for the DOOR Test No.5 (PRS D 5) and the calculation results are compared with the corresponding experimental data to study the code capability to predict the phenomena of the hot gas propagation between two rooms

Full Text Available The Android Operating System finds wide use in smart phones and tablets and is thus suitable for home controllers. This project presents a smart home controller that uses the Bluetooth in an Android device to control the operation of an automated security door system. The software was designed using an Android app that generates a password that is recognized by the Bluetooth to control the opening and closing of the door located at some distance from the user. The Bluetooth module that is installed on the door receives the commands from the android phone and passes these commands to the microcontroller that controls the opening and closing of the door. The design was simulated in Proteus integrated development environment after which the hardware was built on experimental boards. The performance of the system agrees excellently with its conception. The system can be used in various situations where access to an enclosure need to be secured

Full Text Available Panels for openings in structures have always been an essential and integral part of buildings. Their importance in terms of a building´s functionality was not recognised. However, the general view on this issue has changed from focusing on big planar segments and critical details to sub-elements of these structures. This does not only focus on the forms of connecting joints but also on the supporting systems that keep the panels in the right position and ensure they function properly. One of the most strained segments is the threshold structure, especially the entrance door threshold structure. It is the part where substantial defects in construction occur in terms of waterproofing, as well as in the static, thermal and technical functions thereof. In conventional buildings, this problem is solved by pulling the floor structure under the entrance door structure and subsequently covering it with waterproofing material. This system cannot work effectively over the long term so local defects occur. A proposal is put forward to solve this problem by installing a sub-threshold door coupler made of composite materials. The coupler is designed so that its variability complies with the required parameters for most door structures on the European market.

Inflatable door seals are used for airlocks in CANDU stations. They have been a significant source of unreliability and maintenance cost. A program is underway to improve their performance and reliability, backed by environmental qualification testing. Only commercial products and suppliers existed in 1993. For historical reasons, these 'existing products' did not use the most durable material then available. In hindsight, neither had they been adapted nor optimized to combat conditions often experienced in the plants-sagging doors, damaged sealing surfaces, and many thousands of openings and closings per year. Initial attempts to involve the two existing suppliers in efforts to upgrade these seals were unsuccessful. Another suitable supplier had therefore to be found, and a 'new,' COG-owned seal developed; this was completed in 1997. This paper summarizes its testing, along with that of the two existing products. Resistance to aging has been improved significantly. Testing has shown that an accident can be safely withstood after 10 years of service or 40,000 openings-closings, whichever comes first. AECL's Fluid Sealing Technology Unit (FSTU) has invested in the special moulds, test fixtures and other necessary tooling and documentation required to begin commercial manufacture of this new quality product. Accordingly, as with FSTU's other nuclear products such as pump seals, the long-term supply of door seals to CANDU plants is now protected from many external uncertainties-e.g., commercial products being discontinued, materials being changed, companies going out of business. Manufacturing to AECL's detailed specifications is being subcontracted to the new supplier. FSTU is performing the quality surveillance, inspection, testing, and customer service activities concomitant with direct responsibility for supply to the plants. (author)

A door valve is provided which seals cover gas from a liquid metal cooled reactor without leakage therefrom. A threaded shaft is screwed into a heavy box press which is packed with lead. The shaft is adapted to be rotated by an electric motor or a manually operated wheel which is disposed outside of the door valve. From the box press a valve plate is suspended by four linkage bars, one for each corner. Each linkage bar is provided with two wheels which are respectively mounted at the connections with the box press and the valve plate. The wheels are carried on the horizontal grooves formed in a door valve casing. In operation the shaft rotates and travels to permit the box press and the valve plate to move into the door valve casing while the valve plate does not contact the casing. When the box press reaches the home position, the wheels drop into the recesses which are disposed at the ends of the grooves, the valve plate is carried on the valve opening, and the box press presses the valve plate to increase the tightness. The valve plate does not suffer wear as it does not over other parts. (Yamaguchi, T.)

Retrospective cohort study of prospectively collected data. To determine if laminoplasty (LP) is associated with worsening axial neck pain in patients with multilevel cervical myelopathy, and to compare neck pain, clinical outcomes, and radiographic measures in a group undergoing laminectomy and fusion (LF). Postoperative new or worsening axial neck pain is commonly cited as a major disadvantage of laminoplasty. However, there remains a paucity of corroborative data from large series. Following institutional review board approval, we reviewed the medical records, radiographs, and prospective clinical outcomes database of 85 patients undergoing LP and 52 patients undergoing LF for cervical myelopathy with minimum 1-year radiographic follow-up and average clinical follow-up of 18.5 months. LP was performed in those with neutral to lordotic C2-7 alignment and who did not complain of diffuse axial pain. Otherwise, LF was performed. Clinical outcomes included visual analogue score (VAS)-neck pain, VAS-total pain, neck disability index (NDI), short form 36, modified Japanese Orthopaedic Association (mJOA), and several radiographic parameters. VAS-neck did not worsen in LP (-0.2, P = 0.54) and did improve in LF (-2.0, P = 0.0013). VAS-total improved significantly in both groups (LF -1.04 ± 0.52, P = 0.05; LP -1.4 ± 0.51, P = 0.008). NDI improved in both groups, but was significant in only LP (LP decreased 6.79 ± 2.25, P = 0.0032; LF decreased 4.01 ± 3.05, P = 0.19). mJOA scores improved significantly in both groups (LP improved 2.89 ± 0.27, P cervical lordosis in both groups that was significant in LP (LP 2.92° loss, P = 0.0181; LF 1.25° loss, P = 0.53). In a carefully selected group of myelopathic patients without significant diffuse axial pain preoperatively and appropriate sagittal alignment, laminoplasty did not lead to worsening axial neck pain, and it was associated with significant improvements in other

The acetylcholinesterase found in the venom of Bungarus fasciatus (BfAChE) is produced as a soluble, non-amphiphilic monomer with a canonical catalytic domain but a distinct C terminus compared with the other vertebrate enzymes. Moreover, the peripheral anionic site of BfAChE, a surface site located at the active site gorge entrance, bears two substitutions altering sensitivity to cationic inhibitors. Antibody Elec410, generated against Electrophorus electricus acetylcholinesterase (EeAChE), inhibits EeAChE and BfAChE by binding to their peripheral sites. However, both complexes retain significant residual catalytic activity, suggesting incomplete gorge occlusion by bound antibody and/or high frequency back door opening. To explore a novel acetylcholinesterase species, ascertain the molecular bases of inhibition by Elec410, and document the determinants and mechanisms for back door opening, we solved a 2.7-Å resolution crystal structure of natural BfAChE in complex with antibody fragment Fab410. Crystalline BfAChE forms the canonical dimer found in all acetylcholinesterase structures. Equally represented open and closed states of a back door channel, associated with alternate positions of a tyrosine phenol ring at the active site base, coexist in each subunit. At the BfAChE molecular surface, Fab410 is seated on the long Ω-loop between two N-glycan chains and partially occludes the gorge entrance, a position that fully reflects the available mutagenesis and biochemical data. Experimentally based flexible molecular docking supports a similar Fab410 binding mode onto the EeAChE antigen. These data document the molecular and dynamic peculiarities of BfAChE with high frequency back door opening, and the mode of action of Elec410 as one of the largest peptidic inhibitors targeting the acetylcholinesterase peripheral site. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

Influence of the Pressure Difference and Door Swing on Heavy Contaminants Migration between Rooms.
Hendiger, Jacek; Chludzińska, Marta; Ziętek, Piotr
2016-01-01
This paper presents the results of investigations whose aim was to describe the influence of the pressure difference level on the ability of contaminants migration between neighbouring rooms in dynamic conditions associated with door swing. The analysis was based on airflow visualization made with cold smoke, which simulated the heavy contaminants. The test room was pressurized to a specific level and then the door was opened to observe the trail of the smoke plume in the plane of the door. The door was opened in both directions: to the positively and negatively pressurized room. This study focuses on the visualization of smoke plume discharge and an uncertainty analysis is not applicable. Unlike other studies which focus on the analysis of pressure difference, the present study looks at the contaminants which are heavier than air and on "pumping out" the contaminants by means of door swing. Setting the proper level of pressure difference between the contaminated room and the neighbouring rooms can prove instrumental in ensuring protection against toxic contaminants migration. This study helped to establish the threshold of pressure difference necessary to reduce migration of heavy contaminants to neighbouring rooms.
From anonymity to "open doors": IRB responses to tensions with researchers.
Klitzman, Robert
2012-07-03
Tensions between IRBs and researchers in the US and elsewhere have increased, and may affect whether, how, and to what degree researchers comply with ethical guidelines. Yet whether, how, when, and why IRBs respond to these conflicts have received little systematic attention. I contacted 60 US IRBs (every fourth one in the list of the top 240 institutions by NIH funding), and interviewed leaders from 34 (response rate = 55%) and an additional 12 members and administrators. IRBs often try to respond to tensions with researchers and improve relationships in several ways, but range widely in how, when, and to what degree (e.g., in formal and informal structure, content, and tone of interactions). IRBs varied from open and accessible to more distant and anonymous, and in the amount and type of "PR work" and outreach they do. Many boards seek to improve the quantity, quality, and helpfulness of communication with PIs, but differ in how. IRBs range in meetings from open to closed, and may have clinics and newsletters. Memos can vary in helpfulness and tone (e.g., using "charm"). IRBs range considerably, too, in the degrees to which they seek to educate PIs, showing them the underlying ethical principles. But these efforts take time and resources, and IRBs thus vary in degrees of responses to PI complaints. This study, the first to explore the mechanisms through which IRBs respond to tensions and interactions with PIs, suggests that these committees seek to respond to conflicts with PIs in varying ways - both formal and informal, involving both the form and content of communications. This study has important implications for future practice, research, and policy, suggesting needs for increased attention to not only what IRBs communicate to PIs, but how (i.e., the tone and the nature of interactions). IRBs can potentially improve relationships with PIs in several ways: using more "open doors" rather than anonymity, engaging in outreach (e.g., through clinics), enhancing

Locked doors in acute inpatient psychiatry: a literature review.
van der Merwe, M; Bowers, L; Jones, J; Simpson, A; Haglund, K
2009-04-01
Many acute inpatient psychiatric wards in the UK are permanently locked, although this is contrary to the current Mental Health Act Code of Practice. To conduct a literature review of empirical articles concerning locked doors in acute psychiatric inpatient wards, an extensive literature search was performed in SAGE Journals Online, EBM Reviews, British Nursing Index, CINAHL, EMBASE Psychiatry, International Bibliography of the Social Sciences, Ovid MEDLINE, PsycINFO and Google, using the search terms 'open$', 'close$', '$lock$', 'door', 'ward', 'hospital', 'psychiatr', 'mental health', 'inpatient' and 'asylum'. A total of 11 empirical papers were included in the review. Both staff and patients reported advantages (e.g. preventing illegal substances from entering the ward and preventing patients from absconding and harming themselves or others) and disadvantages (e.g. making patients feel depressed, confined and creating extra work for staff) regarding locked doors. Locked wards were associated with increased patient aggression, poorer satisfaction with treatment and more severe symptoms. The limited literature available showed the urgent need for research to determine the real effects of locked doors in inpatient psychiatry.

With the development of artificial intelligence, more and more reliability experts have noticed the roles of subjective information in the reliability design of complex system. Therefore, based on the certain numbers of experiment data and expert judgments, we have divided the reliability estimation based on distribution hypothesis into cognition process and reliability calculation. Consequently, for an illustration of this modification, we have taken the information fusion based on intuitional fuzzy belief functions as the diagnosis model of cognition process, and finished the reliability estimation for the open function of cabin door affected by the imprecise judgment corresponding to distribution hypothesis.

The K-130 cyclotron is in operation at VECC, Kolkata. Recently modernization of the cyclotron has taken place. Central region modification has increased reasonable internal beam current. During the tuning of the projectiles, loss of beam is unavoidable and projectiles hitting different parts of the machine inside the vacuum chamber . These interactions produce prompt radiation comprising neutron and gamma. However machine bunker is not accessible during the operation of the machine. The induced activity produced because of interactions of the primary and secondary radiation a radiation hazardous environment during the shut down for the related maintenance work. Area radiation monitors placed at machine bunker room have the interlock with massive shield door of the bunker. Area radiation monitors are set to specified limiting value, lower than that will allow to open the shield door in normal condition. As, the internal beam current being increased and the probability of beam spread being more. Consequently generation of induced activity is also high leading to delay in machine bunker door opening because of the interlock settings. Radiation dose mapping after a long operation of the machine was done for the different strategic points (The locations mainly people access immediate after shut down). Different consequences and remedial measures being presented in paper to raise the dose rate limit level for the interlocks between the area radiation monitors with machine bunker door, keeping in mind of the regulatory requirements. Raising the limit of dose rate limiting value will minimize the waiting time to access the machine bunker which will increase the duty factor of the machine. (author)

There was a thermal anomaly of the Landsat-7 Enhanced Thematic Mapper Plus (ETM+) radiative cooler cold stage during the cooler outgas phase in flight. With the cooler door in the outgas position and the outgas heaters enabled, the cold stage temperature increased to a maximum of 323 K when the spacecraft was in the sunlight, which was warmer than the 316.3 K upper set point of the outgas heater controller on the cold stage. Also, the outgas heater cycled off when the cold stage was warming up to 323 K. A corrective action was taken before the attitude of the spacecraft was changed during the first week in flight. One orbit before the attitude was changed, the outgas heaters were disabled to cool off the cold stage. The cold stage temperature increase was strongly dependent on the spacecraft roll and yaw. It provided evidence that direct solar radiation entered the gap between the cooler door and cooler shroud. There was a concern that the direct solar radiation could cause polymerization of hydrocarbons, which could contaminate the cooler and lead to a thermal short. After outgas with the cooler door in the outgas position for seven days, the cooler door was changed to the fully open position. With the cooler door fully open, the maximum cold stage temperature was 316.3 K when the spacecraft was in the sunlight, and the duty cycle of the outgas heater in the eclipse was the same as that in the sunlight. It provided more evidence that direct solar radiation had entered the gap between the cooler door and cooler shroud. Cooler outgas continued for seven more days, with the cooler door fully open. The corrective actions had prevented overheating of the cold stage and cold focal plane array (CFPA), which could damage these two components. They also minimized the risk of contamination on the cold stage, which could lead to a thermal short.
DoOR 2.0 - Comprehensive Mapping of Drosophila melanogaster Odorant Responses
Münch, Daniel; Galizia, C. Giovanni
2016-02-01
Odors elicit complex patterns of activated olfactory sensory neurons. Knowing the complete olfactome, i.e. the responses in all sensory neurons for all relevant odorants, is desirable to understand olfactory coding. The DoOR project combines all available Drosophila odorant response data into a single consensus response matrix. Since its first release many studies were published: receptors were deorphanized and several response profiles were expanded. In this study, we add unpublished data to the odor-response profiles for four odorant receptors (Or10a, Or42b, Or47b, Or56a). We deorphanize Or69a, showing a broad response spectrum with the best ligands including 3-hydroxyhexanoate, alpha-terpineol, 3-octanol and linalool. We include all of these datasets into DoOR, provide a comprehensive update of both code and data, and new tools for data analyses and visualizations. The DoOR project has a web interface for quick queries (http://neuro.uni.kn/DoOR), and a downloadable, open source toolbox written in R, including all processed and original datasets. DoOR now gives reliable odorant-responses for nearly all Drosophila olfactory responding units, listing 693 odorants, for a total of 7381 data points.

Metabolomics - A wide-open door to personalized treatment in chronic heart failure?
Marcinkiewicz-Siemion, M; Ciborowski, M; Kretowski, A; Musial, W J; Kaminski, K A
2016-09-15
Heart failure (HF) is a complex syndrome representing a final stage of various cardiovascular diseases. Despite significant improvement in the diagnosis and treatment (e.g. ACE-inhibitors, β-blockers, aldosterone antagonists, cardiac resynchronization therapy) of the disease, prognosis of optimally treated patients remains very serious and HF mortality is still unacceptably high. Therefore there is a strong need for further exploration of novel analytical methods, predictive and prognostic biomarkers and more personalized treatment. The metabolism of the failing heart being significantly impaired from its baseline state may be a future target not only for biomarker discovery but also for the pharmacologic intervention. However, an assessment of a particular, isolated metabolite or protein cannot be fully informative and makes a correct interpretation difficult. On the other hand, metabolites profile analysis may greatly assist investigator in an interpretation of the altered pathway dynamics, especially when combined with other lines of evidence (e.g. metabolites from the same pathway, transcriptomics, proteomics). Despite many prior studies on metabolism, the knowledge of peripheral and cardiac pathophysiological mechanisms responsible for the metabolic imbalance and progression of the disease is still insufficient. Metabolomics enabling comprehensive characterization of low molecular weight metabolites (e.g. lipids, sugars, organic acids, amino acids) that reflects the complete metabolic phenotype seems to be the key for further potential improvement in HF treatment (diet-based or biochemical-based). Will this -omics technique one day open a door to easy patients identification before they have a heart failure onset or its decompensation? Copyright © 2016 Elsevier Ireland Ltd.

Screening of houses might have impact on density of indoor host-seeking Anopheles mosquitoes. A randomized trial of screening windows and doors with metal mesh, and closing openings on eves and walls by mud was conducted to assess if reduce indoor densities of biting mosquitoes. Mosquitoes were collected in forty houses using Centers for Diseases Control and Prevention (CDC) light traps biweekly in March and April 2011. A randomization of houses into control and intervention groups was done based on the baseline data. Windows and doors of 20 houses were screened by metal mesh, and openings on the walls and eves closed by mud and the rest 20 houses were used as control group. Mosquitoes were collected biweekly in October and November 2011 from both control and intervention houses. A Generalized Estimating Equations (GEE) with a negative binomial error distribution was used to account for over dispersion of Anopheles arabiensis and culicine counts and repeated catches made in the same house. Screening doors and windows, and closing openings on eves and wall by mud reduced the overall indoor densities of An. arabiensis by 40%. The effect of screenings pronounced on unfed An. arabiensis by resulting 42% reduction in houses with interventions. The total costs for screening windows and doors, and to close openings on the eves and walls by mud was 7.34 USD per house. Screening houses reduced indoor density of An. arabiensis, and it was cheap and can easily incorporated into malaria vector strategies by local communities, but improving doors and windows fitness for screening should be considered during house construction to increase the efficacy of screenings.

There is disagreement among psychiatric professionals about whether the doors of acute psychiatric wards should be kept locked to prevent patients from leaving and harming themselves or others. This study explored patient, staff, and visitor perceptions about the acceptability of locking the ward door on acute psychiatric inpatient wards. Interviews were conducted with 14 registered nurses, 15 patients, and six visitors from three different acute wards. Findings revealed commonalities across all groups, with general agreement that locking the door reduced absconding. Staff expressed feelings of guilt, embarrassment, and fear of being blamed when a patient absconded. Staff also reported that open wards created anxious vigilance to prevent an abscond and increased workload in allocating staff to watch the door, whereas staff on partially-locked doors also perceived an increased workload in letting people in and out of the ward. Patients had mixed feelings about the status of the door, expressing depression, a sense of stigma, and low self-esteem when the door was locked. The issue of balancing safety and security on acute psychiatric wards against the autonomy of patients is not easily resolved, and requires focused research to develop innovative nursing practices. © 2011 The Authors.

The purpose of this study is to evaluate the efficacy of laminoplasty in the treatment of spinal cord injury (SCI) without instability. 79 patients with SCI without instability who underwent surgical treatment in our institute between January 2005 and September 2012 were retrospectively reviewed. Twenty nine patients fulfilled the inclusion criteria as follows: SCI without instability, spinal cord contusion in MRI, cervical stenosis more than 20%, follow up at least 6 months. Preoperative neurological state, clinical outcome and neurological function was measured using the American Spinal Injury Association (ASIA) impairment scale, modified Japanese Orthopedic Association (mJOA) grading scale and Hirabayashi recovering rate. Seventeen patients showed improvement in ASIA grade and twenty six patients showed improvement in mJOA scale at 6 month follow up. However, all patients with ASIA grade B and C have shown improvement of one or more ASIA grade. Mean Hirabayashi recovery rate was 47.4±23.7%. There was better neurologic recovery in those who had cervical spondylosis without ossification of posterior longitudinal ligament (OPLL) (pcervical canal stenosis, especially spondylosis without OPLL and neurologic deterioration in ASIA B, C and D.

Improving Door-to-balloon Time by Decreasing Door-to-ECG time for Walk-in STEMI Patients
Directory of Open Access Journals (Sweden)
Coyne, Christopher J.
2014-12-01
Full Text Available Introduction: The American Heart Association/American College of Cardiology guidelines recommend rapid door-to-electrocardiography (ECG times for patients with ST-segment elevation myocardial infarction (STEMI. Previous quality improvement research at our institution revealed that we were not meeting this benchmark for walk-in STEMI patients. The objective is to investigate whether simple, directed changes in the emergency department (ED triage process for potential cardiac patients could decrease door-to-ECG times and secondarily door-to-balloon times. Methods: We conducted an interventional study at a large, urban, public teaching hospital from April 2010 to June 2012. All patients who walked into the ED with a confirmed STEMI were enrolled in the study. The primary intervention involved creating a chief complaint-based “cardiac triage” designation that streamlined the evaluation of potential cardiac patients. A secondary intervention involved moving our ECG technician and ECG station to our initial triage area. The primary outcome measure was door-to-ECG time and the secondary outcome measure was door-to-balloon time. Results: We enrolled 91 walk-in STEMI patients prior to the intervention period and 141 patients after the invention. We observed statistically significant reductions in door-to-ECG time (43±93 to 30±72 minutes, median 23 to 14 minutes p<0.01, ECG-to-activation time (87±134 to 52±82 minutes, median 43 to 31 minutes p<0.01, and door-to-balloon time (134±146 to 84±40 minutes, median 85 -75 minutes p=0.03. Conclusion: By creating a chief complaint-based cardiac triage protocol and by streamlining ECG completion, walk-in STEMI patients are systematically processed through the ED. This is not only associated with a decrease in door-to-balloon time, but also a decrease in the variability of the time sensitive intervals of door-to-ECG and ECG-to-balloon time.

Real-time door detection for indoor autonomous vehicle
He, Zhihao; Zhu, Ming
2017-07-01
Indoor Autonomous Vehicle(IAV) is used in many indoor scenes. Such as hotels and hospitals. Door detection is a key issue to guide the IAV into rooms. In this paper, we consider door detection in the use of indoor navigation of IAV. Since real-time properties are important for real-world IAV, the detection algorithm must be fast enough. Most monocular-camera based door detection model need a perfect detection of the four line segments of the door or the four corners. But in many situations, line segments could be extended or cut off. And there could be many false detected corners. And few of them can distinguish doors from door-like objects with door-like shape effectively. We proposed a 2-D vision model of the door that is made up of line segments. The number of parts detected is used to determine the possibility of a door. Our algorithm is tested on a database of doors.1 The robustness and real-time are verified. The precision is 89.4%. Average time consumed for processing a 640x320 figure is 44.73ms.
Self-testing security sensor for monitoring closure of vault doors and the like

A self-testing device is provided for a monitoring system for monitoring whether a closure member such as a door or window is closed. The monitoring system includes a switch unit mounted on the frame of the closure member being monitored and including magnetically biased switches connected in one or more electrical monitoring circuits, and a door magnet unit mounted on the closure member being monitored. The door magnet includes one or more permanent magnets that produce a magnetic field which, when the closure member is closed, cause said switches to assume a first state. When the closure member is opened, the switches switch to a second, alarm state. The self-testing device is electrically controllable from a remote location and produces a canceling or diverting magnetic field which simulates the effect of movement of the closure member from the closed position thereof without any actual movement of the member. 5 figs

2000-04-01
Patients with cervical compression myelopathy were studied to elucidate the mechanism underlying boomerang deformity, which results from the migration of the cervical spinal cord between split laminae after laminoplasty with median splitting of the spinous processes (boomerang sign). Thirty-nine cases, comprising 25 patients with cervical spondylotic myelopathy, 8 patients with ossification of the posterior longitudinal ligament, and 6 patients with cervical disc herniation with developmental canal stenosis, were examined. The clinical and radiological findings were retrospectively compared between patients with (B group, 8 cases) and without (C group, 31 cases) boomerang sign. Moderate increase of the grade of this deformity resulted in no clinical recovery, although there was no difference in clinical recovery between the two groups. Most boomerang signs developed at the C4/5 and/or C5/6 level, where maximal posterior movement of the spinal cord was achieved. Widths between lateral hinges and between split laminae in the B group were smaller than in the C group. Flatness of the spinal cord in the B group was more severe than in the C group. In conclusion, the boomerang sign was caused by posterior movement of the spinal cord, narrower enlargement of the spinal canal and flatness of the spinal cord.

Nowadays, additive manufacturing method has been used extensively to realize any product with specific attributes rather than the conventional subtractive manufacturing method. For instance, the additive manufacturing has enable us to construct a product layer-by-layer by successively depositing several materials in one session and one platform. This paper studied the properties of a 3D printed scaffold fabricated through Poly(Lactic-acid) (PLA) deposition modelling in combination with injectable hydroxyapatite (HA)/alginate as cell carrier. The scaffold was designed to serve as a spacer in cervical laminoplasty. Therefore, a series of test were conducted to elaborate the mechanical property, porosity and in-vitro toxicity testing. The results showed that the method is reliable to fabricate the scaffold as desired although the toxicity test needs more confirmation.

An unexpected knock on Corrigan's secret door.

2010-10-01
Corrigan's secret door describes a metaphorical escape route for busy physicians. The term was derived from the successful and exceptionally busy professional life of Irish physician Dominic John Corrigan (1802-80). It is claimed that Corrigan's outpatient clinic was so busy that he required a secret door in his consulting rooms to escape from the ever-growing queue of eager patients. The origins of this charming story are unknown, and the door may have never existed. However, at present, Corrigan's secret door is often quoted when busy physicians have their own little ways in surviving a stressful professional life. Generations of British-trained doctors have grown up with Corrigan's secret door, as it was featured in the introduction of the Oxford Handbook of Clinical Medicine. Accordingly, trainees as well as more senior doctors are often reminded that having a 'secret door' is vital in surviving in the medical profession. My own escape is through classical music and the violoncello, in particular. As the name implies, my own secret door is normally invisible to colleagues and patients. This little article is about a patient who found me out, and a reflection on the role of classical music and the cello in my professional life.

Since this facility was constructed at basement floor, all process materials, equipment and radioactive materials are take in and out through the rear door. Also, this door can be an access route of workers for the maintenance works. Therefore ACP hot-cell rear doors must maintain the radiation shielding, sealing, mechanical and structural safety. This report presents design criteria, design contents of each part and driving part. It was confirmed that the rear doors sufficiently maintain the safety through the structural analysis and shielding analysis. Also, it was confirmed that the rear doors were constructed as designed by the gamma scanning test after the installation.

A pool door is installed at the chase of the pool gate by means of an overhead crane in the building of a research reactor. The principal function of the pool door, which is located between the reactor pool and service pool, is to separate the reactor pool from the service pool for the maintenance and/or the removal of the equipment either in the reactor pool or service pool. The pool door consists of stainless steel plates supported by structural steel frames and sealing components. The pool door is equipped with double inflatable gaskets. The configuration of the pool door is shown in Figure 1. The FEM analysis and theoretical calculation by the formula were performed to evaluate the natural frequency for the pool door in the water. The results from the two methods were compared.

Building indoors reconstruction is an active research topic due to the importance of the wide range of applications to which they can be subjected, from architecture and furniture design, to movies and video games editing, or even crime scene investigation. Among the constructive elements defining the inside of a building, doors are important entities in applications like routing and navigation, and their automated recognition is advantageous e.g. in case of large multi-storey buildings with many office rooms. The inherent complexity of the automation of the recognition process is increased by the presence of clutter and occlusions, difficult to avoid in indoor scenes. In this work, we present a pipeline of techniques used for the reconstruction and interpretation of building interiors using information acquired in the form of point clouds and images.

Doors for memory: A searchable database.
Baddeley, Alan D; Hitch, Graham J; Quinlan, Philip T; Bowes, Lindsey; Stone, Rob
2016-11-01
The study of human long-term memory has for over 50 years been dominated by research on words. This is partly due to lack of suitable nonverbal materials. Experience in developing a clinical test suggested that door scenes can provide an ecologically relevant and sensitive alternative to the faces and geometrical figures traditionally used to study visual memory. In pursuing this line of research, we have accumulated over 2000 door scenes providing a database that is categorized on a range of variables including building type, colour, age, condition, glazing, and a range of other physical characteristics. We describe an illustrative study of recognition memory for 100 doors tested by yes/no, two-alternative, or four-alternative forced-choice paradigms. These stimuli, together with the full categorized database, are available through a dedicated website. We suggest that door scenes provide an ecologically relevant and participant-friendly source of material for studying the comparatively neglected field of visual long-term memory.

Traumatic asphyxia--fatal accident in an automatic revolving door.
Cortis, J; Falk, J; Rothschild, M A
2015-09-01
Due to continuing modernisation, the number of automatic doors in routine use, including powered revolving doors, has increased in recent years. Automatic revolving doors are found mostly in department stores, airports, railway stations and hospitals. Although safety arrangements and guidelines concerning the installation of automatic doors are in existence, their disregard in conjunction with obsolete or incorrect installation can lead to fatal accidents. In this report, a 19-month-old boy is described whose right arm was caught between the elements of an automatic revolving door. As a direct result of rescue attempts, the child's body was drawn further into the narrow gap between elements of the door. To get the boy's body out of the 4-cm-wide gap between the fixed outer wall of the revolving door and the revolving inner, back-up batteries had to be disconnected so as to stop the electrical motor powering the door. Cardiopulmonary resuscitation was begun immediately after the rescue but was unsuccessful; the child was declared dead at the hospital he was taken to. The cause of death was a combination of compression-related skull and brain injury together with thoracic compression. This case shows an outstanding example of the preventive aspect as a special task of forensic medicine. Additionally, it serves as a warning for the correct installation and use of automatic revolving doors. Even so, small children should not use these doors on their own, but only with an alert companion, so as to prevent further fatal accidents of this sort.

Blower-door techniques for measuring interzonal leakage
Energy Technology Data Exchange (ETDEWEB)
Hult, Erin L.; Sherman, Max H.; Walker, Iain
2013-01-01
Abstract The standard blower door test methods, such as ASTM E779, describe how to use a single blower door to determine the total leakage of a single-zone structure such as a detached single-family home. There are no standard test methods for measuring interzonal leakage in a two-zone or multi-zone building envelope such as might be encountered in with an attached garage or in a multifamily building. Some practitioners have been using techniques that involve making multiple measurements with a single blower door as well as combined measurements using multiple blower doors. Even for just two zones there are dozens of combinations of one-door and two-door test protocols that could conceivably be used to determine the interzonal air tightness. We examined many of these two-zone configurations using both simulation and measured data to estimate the accuracy and precision of each technique for realistic measurement scenarios. We also considered the impact of taking measurements at a single pressure versus over multiple pressures. We compared the various techniques and evaluated them for specific uses. Some techniques work better in one leakage regime; some are more sensitive to wind and other noise; some are more suited to determining only a subset of the leakage values. This paper makes recommendations on which techniques to use or not use for various cases and provides data that could be used to develop future test methods.

To describe nurses' and mental health nurse assistants' perceptions of advantages and disadvantages about working on a psychiatric ward with a locked entrance door. Psychiatric staff sometimes needs to protect patients from harming themselves or others. To keep the entrance door locked may help staff to achieve this goal. How locked entrance doors at psychiatric wards are experienced by staff, working on these wards, has been investigated to a very limited extent. The study was explorative and descriptive. Audio taped, semi-structured interviews with open-ended questions about advantages and disadvantages about working on a psychiatric ward with a locked entrance door, were conducted with 20 nurses and 20 mental health nurse assistants. Data were analyzed with content analysis. A content analysis revealed eight categories of advantages and 18 categories of disadvantages. Most advantages mentioned by nurses and mental health nurse assistants were categorized as providing staff with control over patients, providing patients with a secure and efficient care and protecting patients and staff against 'the outside'. Most disadvantages mentioned by nurses were categorized as causing extra work for staff, making patients feel confined, making patients feel dependent and creating a non-caring environment. Most disadvantages mentioned by mental health nurse assistants were categorized as causing extra work for staff, making patients feel confined, causing emotional problems for patients, making staff's power obvious and forcing patients to adapt to other patients' needs. Nurses and mental health nurse assistants mentioned more disadvantages than advantages and nurses mentioned more disadvantages than mental health nurse assistants. Nurses and mental health nurse assistants perceive a number of advantages and disadvantages for themselves, patients and significant others with a locked door at a psychiatric ward. Most of these concern patients' experiences. It is important for

Detecting Signage and Doors for Blind Navigation and Wayfinding.
Wang, Shuihua; Yang, Xiaodong; Tian, Yingli
2013-07-01
Signage plays a very important role to find destinations in applications of navigation and wayfinding. In this paper, we propose a novel framework to detect doors and signage to help blind people accessing unfamiliar indoor environments. In order to eliminate the interference information and improve the accuracy of signage detection, we first extract the attended areas by using a saliency map. Then the signage is detected in the attended areas by using a bipartite graph matching. The proposed method can handle multiple signage detection. Furthermore, in order to provide more information for blind users to access the area associated with the detected signage, we develop a robust method to detect doors based on a geometric door frame model which is independent to door appearances. Experimental results on our collected datasets of indoor signage and doors demonstrate the effectiveness and efficiency of our proposed method.

Full Text Available Abstract Introduction The drugs gabapentin and ketamine are used frequently in the peri-operative setting. There is poor documentation whether or not gabapentin and ketamine interact to cause prolonged depression of the central nervous system. Case Presentation The following is a case report in which a patient, a 58-year-old African-American man, with a history of post-traumatic stress disorder and chronic pain underwent a cervical laminoplasty procedure. The patient presented post-operatively in a dissociative state with paralysis, anarthria and preservation of consciousness. All organic causes were excluded, with the exception of prolonged central nervous system depression from a gabapentin/ketamine drug interaction. A new onset conversion disorder could also not be excluded. Conclusion Although this case by itself is not enough evidence to substantiate a true adverse reaction between gabapentin and ketamine, it is enough to warrant further investigation.

Chronic pain is characterized by a complex interaction of somatic, mental and social factors. Assessing these factors in patients with chronic pain is vital during the diagnostic work-up and when making a structured treatment plan. Interdisciplinary pain assessment (ISA) is the most promising method to deal with these challenges. This article presents our experience in performing pain assessments in the hospital setting and also illustrates the characteristic features of chronic pain patients undergoing such assessments. This study reviews and evaluates patient data from 2704 ISAs performed at the Interdisciplinary Pain Centre of the Zentralklinik Bad Berka, Germany, between 2008 and 2015. The majority of our ISA patients are severely handicapped and show distinct signs of chronic disease. A large proportion of patients is either unable to work or receiving benefits (invalidity pension or retirement pension). In addition, patients reported long disease durations and high emotional distress. Treatment recommendations were based on the patients' individual clinical presentations and examination results. More than half of the patients required multimodal pain management, while adjustments or therapeutic withdrawal of pain medications, in particular of opioids, were indicated in many patients. Our study shows that ISA enables fast, high-quality diagnostic assessments of chronic pain while taking the biopsychosocial model of pain in particular into account. In addition, ISA is not biased with regard to outcome results and recommends the further treatment that appears best for the individual patient. ISA leads not only to inpatient treatment, but also to treatment in other therapeutic settings and, as such, is not merely a door-opener to multimodal pain therapy.

A Study on the Modeling of the Oil Damper in an Auto-Door Hinge
International Nuclear Information System (INIS)
Ha, Kwang Soon; Kim, Jong Tae; Kim, Hwan Yeol
2009-11-01
An auto-door hinge, which is one of the automatic door-closing apparatuses, has been widely used to prevent fire propagations in living or commercial buildings. The auto-door hinge consists of a spring to accumulate power for closing a door and an oil damper to control door-closing velocity. To predict and optimize the temporal door behavior during the door-closing period, the auto-door closing system was modeled as a second order-damping system. And a damping coefficient of the oil damper was also theoretically modeled by analyzing Newtonian, incompressible, viscous flow through an oil passage between a oil control rod and a oil piston body. The temporal door behaviors during the door-closing period were predicted with respect to the gap distance of the oil passage, oil viscosity, and pre-compressing of the spring. Temporal door behavior measurement method using an encoder system was also developed to validate the modelling on the oil damping system. As using the developed test apparatus, the temporal door position, velocity, and rotational torque were measured, and the modelling method was evaluated

From acoustic descriptors to evoked quality of car door sounds.
Bezat, Marie-Céline; Kronland-Martinet, Richard; Roussarie, Vincent; Ystad, Sølvi
2014-07-01
This article describes the first part of a study aiming at adapting the mechanical car door construction to the drivers' expectancies in terms of perceived quality of cars deduced from car door sounds. A perceptual cartography of car door sounds is obtained from various listening tests aiming at revealing both ecological and analytical properties linked to evoked car quality. In the first test naive listeners performed absolute evaluations of five ecological properties (i.e., solidity, quality, weight, closure energy, and success of closure). Then experts in the area of automobile doors categorized the sounds according to organic constituents (lock, joints, door panel), in particular whether or not the lock mechanism could be perceived. Further, a sensory panel of naive listeners identified sensory descriptors such as classical descriptors or onomatopoeia that characterize the sounds, hereby providing an analytic description of the sounds. Finally, acoustic descriptors were calculated after decomposition of the signal into a lock and a closure component by the Empirical Mode Decomposition (EMD) method. A statistical relationship between the acoustic descriptors and the perceptual evaluations of the car door sounds could then be obtained through linear regression analysis.
Understanding "revolving door" patients in general practice: a qualitative study.
Williamson, Andrea E; Mullen, Kenneth; Wilson, Philip
2014-02-13
'Revolving door' patients in general practice are repeatedly removed from general practitioners' (GP) lists. This paper reports a qualitative portion of the first mixed methods study of these marginalised patients. We conducted qualitative semi-structured interviews with six practitioner services staff and six GPs in Scotland, utilizing Charmazian grounded theory to characterise 'revolving door' patients and their impact from professionals' perspectives. 'Revolving door' patients were reported as having three necessary characteristics; they had unreasonable expectations, exhibited inappropriate behaviours and had unmet health needs. A range of boundary breaches were reported too when 'revolving door' patients interacted with NHS staff. We utilise the 'sensitising concepts' of legitimacy by drawing on literature about 'good and bad' patients and 'dirty work designations.' We relate these to the core work of general practice and explore the role that medical and moral schemas have in how health service professionals understand and work with 'revolving door' patients. We suggest this may have wider relevance for the problem doctor patient relationship literature.

Full Text Available Door width is one of the important factors to concern in layout or facilities design because it affects directly to traffic speed and overall traffic time simultaneously. Nowadays, common assessment method is computer simulation which is still not realistic due to the unchanged speed of model while walking through a door. This research aims to study an effect of door width to individual walking speed. Sixty subjects participated in the experiment and performed task by walking through the door that is set the width as 40, 50, 60, 70, 80, 90 and 100 centimetres. The optical motion capture system was used to determine walking speed. The results showed that Fitts’ law was applied to the participants with high weight. Door width below 70 centimetres significantly affected to changing speed at 0-0.5 m. before the door. Additionally, human size also affected changing speed. The factors include shoulder breadth, weight and interaction between shoulder breadth and weight were found to be significant. These factors explained 54.2% of changing speed.

To introduce a new surgical approach to the multilevel ossification of the ligamentum flavum (OLF) aided by three-dimensional (3D) printing technology. A multilevel OLF patient (male, 66 years) was scanned using computed tomography (CT). His saved DICOM format data were inputted to the Mimics14.0 3D reconstruction software (Materialise, Belgium). The resulting 3D model was used to observe the anatomical features of the multilevel OLF area and to design the surgical approach. At the base of the spinous process, two channels were created using an osteotomy bilaterally to create a "V" shape to remove the bone ligamentous complex (BLC). The decompressive laminoplasty using mini-plate fixation was simulated with the computer. The physical model was manufactured using 3D printing technology. The patient was subsequently treated using the designed surgery. The operation was completed successfully without any complications. The operative time was 90 min, and blood loss was 200 ml. One month after the operation, neurologic function was recovered well, and the JOA score was improved from 6 preoperatively to 10. Postoperative CT scanning showed that the OLF was totally removed, and the replanted BLC had not subsided. 3D printing technology is an effective, reliable, and minimally invasive method to design operations. The technique can be an option for multilevel OLF surgical treatment. This can provide sufficient decompression with minimum damage to the spine and other intact anatomical structures.

Epidemiological analysis in a universitary paediatric emergency unit of children admitted after accidental injuries resulting from fingers crushed in a door. Prospective, descriptive cohort study from September 6th, 2004 to July 1st, 2005 included all children admitted for finger injuries crushed in a non-automatic door. included accidents due to automatic doors, toy's or refrigerator doors, families who refused to participate to the study or families who had left the waiting area before medical examination. Collected data were patient and family characteristics, accident characteristics and its management. Three hundred and forty children affected by 427 digital lesions were included. The mean age was 5.5+/-3.8 years (range 4 months - 15.5 years). Male/female ratio was equal to 1.2: 1. Fifty-eight percent of patients belonged to families composed of 3 or more siblings. Ninety-three per cent of families came to hospital within the first 2 hours after the accident (mean delay 99+/-162 min, median range 54 minutes). Location of the accident was: domestic (62%, at home (64%)), at school (17%). Locations within the home were: the bedroom (33%), bathroom and toilets (21%). An adult was present in 75% of cases and responsible for the trauma in 25% of accidents, another child in 44%. The finger or fingers were trapped on the hinge side in 57% of patients. No specific safeguard devices were used by 94% of families. Among victims, 20% had several crushed digits; left and right hand were injured with an equal frequency. The commonest involved digits were: the middle finger (29%), the ring finger (23%). The nail plate was damaged in 60% of digital lesions, associated with a wound (50%), a distal phalanx fracture (P3) (12%). Six children had a partial or complete amputation of P3, 2 children a lesion of the extensor tendon, 1 child had a rupture of the external lateral ligament.

Full Text Available An estimated 60,000 people die of rabies annually. The vast majority of cases of human rabies develop following a bite from an infected dog. Rabies can be controlled in both human and canine populations through widespread vaccination of dogs. Rabies is particularly problematic in Malawi, costing the country an estimated 13 million USD and 484 human deaths annually, with an increasing paediatric incidence in Blantyre City. Consequently, the aim of this study was to vaccinate a minimum of 75% of all the dogs within Blantyre city during a one month period. Blantyre's 25 administrative wards were divided into 204 working zones. For initial planning, a mean human:dog ratio from the literature enabled estimation of dog population size and dog surveys were then performed in 29 working zones in order to assess dog distribution by land type. Vaccination was conducted at static point stations at weekends, at a total of 44 sites, with each operating for an average of 1.3 days. On Monday to Wednesday, door-to-door vaccination sessions were undertaken in the areas surrounding the preceding static point stations. 23,442 dogs were vaccinated at static point stations and 11,774 dogs were vaccinated during door-to-door vaccinations. At the end of the 20 day vaccination programme, an assessment of vaccination coverage through door-to-door surveys found that of 10,919 dogs observed, 8,661 were vaccinated resulting in a vaccination coverage of 79.3% (95%CI 78.6-80.1%. The estimated human:dog ratio for Blantyre city was 18.1:1. Mobile technology facilitated the collection of data as well as efficient direction and coordination of vaccination teams in near real time. This study demonstrates the feasibility of vaccinating large numbers of dogs at a high vaccination coverage, over a short time period in a large African city.

Confounding adjustment through front-door blocking in longitudinal studies
Directory of Open Access Journals (Sweden)
Arvid Sjölander
2013-03-01
Full Text Available A common aim of epidemiological research is to estimate the causal effect of a particular exposure on a particular outcome. Towards this end, observed associations are often ‘adjusted’ for potential confounding variables. When the potential confounders are unmeasured, explicit adjustment becomes unfeasible. It has been demonstrated that causal effects can be estimated even in the presence of umeasured confounding, utilizing a method called ‘front-door blocking’. In this paper we generalize this method to longitudinal studies. We demonstrate that the method of front-door blocking poses a number of challenging statistical problems, analogous to the famous problems associ- ated with the method of ‘back-door blocking’.

European cities increasingly face problems caused by transport and traffic. A key factor for all transport operators is the quality of the passenger experience as this particularly, affects the uptake of the service. A comprehensive study (METPEX FP7 EU project - www.metpex.eu) developed by a consortium of 16 European partners has analysed the quality of the whole journey (door-to-door) passenger experience, including private or individual forms transport and attending to specific need of users’ groups. For this purpose, a tool with a technological basis was used to collect data from 8 trial cities: Bucharest (Romania), Coventry (United Kingdom), Dublin (Ireland), Grevena (Greece), Rome (Italy), Stockholm (Sweden), Valencia (Spain) and Vilnius (Lithuania); and five FIA motorist networks countries. For a correct evaluation of quality experience, it was deployed a subset of key variables derived from the comprehensive set of potential satisfaction factors that were studied for each pilot city. In this paper, results of the travel experience are showed, including analysis of variables affecting behavior and feelings of passengers. (Author)

Rotational and frictional dynamics of the slamming of a door
Klein, Pascal; Müller, Andreas; Gröber, Sebastian; Molz, Alexander; Kuhn, Jochen
2017-01-01
A theoretical and experimental investigation of the rotational dynamics, including friction, of a slamming door is presented. Based on existing work regarding different damping models for rotational and oscillatory motions, we examine different forms for the (angular) velocity dependence (ωn, n = 0, 1, 2) of the frictional force. An analytic solution is given when all three friction terms are present and several solutions for specific cases known from the literature are reproduced. The motion of a door is investigated experimentally using a smartphone, and the data are compared with the theoretical results. A laboratory experiment under more controlled conditions is conducted to gain a deeper understanding of the movement of a slammed door. Our findings provide quantitative evidence that damping models involving quadratic air drag are most appropriate for the slamming of a door. Examining this everyday example of a physical phenomenon increases student motivation, because they can relate it to their own personal experience.

Eric Forcael
Full Text Available The last Chilean earthquake, occurred on February 27, 2010, allowed establishing important patterns of structural failures in reinforced concrete residential buildings; however, limited progress has been made in the study of basic standards of serviceability, such as obstruction of doors. Thus, this study focused on measuring the influence of design specifications and construction criteria of lintels and columns, in terms of obstruction of doors, considering capacity thresholds for certain levels of displacement. The study consisted of the design and construction of a full-scale prototype of a reinforced concrete frame, designed in accordance with all the ACI-318-08 requirements, taking into account typical aspects of geometry and materiality widely used by the real estate industry, for location and size of doors. In order to quantify the structural capacity of the prototype and to study the serviceability of the door, a quasi-static cyclic test was conducted, according to load and displacement protocols specified in FEMA 356 and FEMA 461, which was adjusted by using virtual models based on a static nonlinear analysis called "Pushover". This research verified that, for displacement levels even five times higher than those established by codes considered, the cracking degree was minimal and fully recoverable. It was also found the door evidenced malfunction when the displacements were greater than those specified by design only, validating a high degree of accomplishment of current codes, in terms of capacity and serviceability, when dealing with obstruction of residential doors.

Design, development and testing of a high speed door for a blast containment fixture
International Nuclear Information System (INIS)
Shapiro, C.
1991-01-01
This paper reports that the concept of a large door able to close over a three foot diameter hole in less than 50 milliseconds evolved during the design of a test containment fixture at the Idaho National Engineering laboratory (INEL). This facility was designed for use at the Aberdeen Proving Ground (APG) in Aberdeen, Maryland. EPA regulations required new technologies for blast containment at APG, which culminated in the design of the blast chamber with a high speed door at its entrance. The main requirement of the fixture is to contain large explosion pressure pulses and explosive by-products during a variety of test scenarios. The door was designed to allow entrance of test projectiles and then to close over the entrance hole to contain explosive by-products inside the fixture. The speed of the projectile and the resultant blast pressure pulse required door closure within 56 msec. Analytical modelling of the door closure indicated velocities of up to 150 ft/sec before impact, for closure within the required time. Lightweight materials were used for the moving parts to minimize this impact force, including aluminum honeycomb composite panels and energy absorbers. Actuation was accomplished with a standard explosive bolt. High pressure nitrogen accelerated the door during closure. Time measurement for the door closer were obtained using high speed video equipment

Originally designed to use at launcher and receiver pig traps on offshore, area, the quick opening closure, presented at this work, it has technical features that assure a singular performance. The safety is assured by the 'vent bleed screw' that stop the blockage mechanism in closed position until it to be totally removed. A limited pressure bleed, give a warning that there is pressure in the vessel. The height quality of the door and external ring grinding surfaces added to the circular block segments system mechanism give a same pressure all over the o'ring surface. This assure the leak proof warranty. The open an close Asca system composed by circular blocks segments more the push pull mechanism actuated by the same davit-screw that lift the door, provide a quick, safety and ease operation. The care at the design and the manufacture quality of the parts prevent grip rings and the door opening operation failure. (author)

Full Text Available The objective of this paper is to examine and identify barriers to and enablers for the European rail freight transport services as a transport chain partner along the supply chains in the changing market scenario. The changing market scenario includes, among others, requiring 'door-to-door' rather than 'terminal to terminal' and integrated service, competitive ability to attract non-rail cargo type, changes in the customer requirements (e.g. reliable service and changes in the operational requirements and practices. Using a literature review method, the paper is presented in two parts. The part 1 focuses on the identification of barriers to the European rail freight service by reviewing freight logistics services for global supply chains followed by the current performance of European rail freight transport followed by a discussion on the rail freight market liberalisation in Europe. Then rail freight transport in the Unites States (U.S. is discussed. The research notes that although the background, scope and necessity for reform measures in Europe differ from those of the U.S., some lessons can be learned and the main lesson is that an appropriate reform measure can enhance rail sector competitive ability in Europe. The part 2 of the paper is dedicated to recommend some concrete steps and actions as enablers to remove the barriers identified in the part 1 to develop multimodal rail freight transport. The enablers for multimodal rail freight transport include: •\tEuropean rail freight transport market needs full liberalisation so that incumbent and new entrants can compete freely. •\tThe rail operators need to acquire service (e.g. customer tailored services, door to door service quality offered by road freight operators. •\tThey need to conduct a combination of ‘terminal-to-terminal’ and door-to-door operations, as and when needed; •\tThey must build partnership with freight forwarder or 3PLs to include all types of customers

Indoor Modelling from Slam-Based Laser Scanner: Door Detection to Envelope Reconstruction
Díaz-Vilariño, L.; Verbree, E.; Zlatanova, S.; Diakité, A.
2017-09-01
Updated and detailed indoor models are being increasingly demanded for various applications such as emergency management or navigational assistance. The consolidation of new portable and mobile acquisition systems has led to a higher availability of 3D point cloud data from indoors. In this work, we explore the combined use of point clouds and trajectories from SLAM-based laser scanner to automate the reconstruction of building indoors. The methodology starts by door detection, since doors represent transitions from one indoor space to other, which constitutes an initial approach about the global configuration of the point cloud into building rooms. For this purpose, the trajectory is used to create a vertical point cloud profile in which doors are detected as local minimum of vertical distances. As point cloud and trajectory are related by time stamp, this feature is used to subdivide the point cloud into subspaces according to the location of the doors. The correspondence between subspaces and building rooms is not unambiguous. One subspace always corresponds to one room, but one room is not necessarily depicted by just one subspace, for example, in case of a room containing several doors and in which the acquisition is performed in a discontinue way. The labelling problem is formulated as combinatorial approach solved as a minimum energy optimization. Once the point cloud is subdivided into building rooms, envelop (conformed by walls, ceilings and floors) is reconstructed for each space. The connectivity between spaces is included by adding the previously detected doors to the reconstructed model. The methodology is tested in a real case study.

A demonstration facility for advanced spent fuel conditioning process (ACP) is under construction in KAERI. In this hot cell facility, all process equipment and materials are taken in and out only through the rear door. The working table in front of the process rear door is specially designed to be openable for the efficient use of the space. This paper presents the structural safety analysis of the openable working table, for the normal operational load condition and accidental drop condition of heavy object. Both cases are investigated through static and dynamic finite element analyses. The analysis results show that structural safety of the working table is sufficiently assured and the working table is not collapsed even when an object of 500 kg is dropped from the height of 50 cm.
Solar cell degradation under open circuit condition in out-doors-in desert region
Directory of Open Access Journals (Sweden)
M. Boussaid
Full Text Available The reliability of solar cells is an important parameter in the design of photovoltaic systems and particularly for cost estimation. Solar cell degradation is the result of various operating conditions; temperature is one of most important factors. Installed PV modules in desert regions are subjected to various temperature changes with significant gradient leading to accelerated degradation. In the present work, we demonstrate the influence of open-circuit condition on the degradation of PV modules. The experiment is carried out in the desert region of ADRAR (southern Algeria using two modules IJISEL of single-crystal silicon. A continuous monitoring allows analysis of both performances of modules for duration of 330 days. The module in open-circuit condition reaches higher temperature means than the module in charging condition; therefore, it undergoes a higher degradation. By simulation, we found that the life of a PV module (whose power output is close to 50% in a condition of an open-circuit in the desert region could be reduced to 4 years, and that has a significant impact on economy.

We report a thorough analysis of the intermittent flow of pedestrians through a narrow door. The observations include five different sets of evacuation drills with which we have investigated the effect of door size and competitiveness on the flow dynamics. Although the outcomes are in general compatible with the existence of the faster-is-slower effect, the temporal evolution of the instantaneous flow rate provides evidence of new features. These stress the crucial role of the number of people performing the tests, which has an influence on the obtained results. Once the transients at the beginning and end of the evacuation are removed, we have found that the time lapses between the passage of two consecutive pedestrians display heavy-tailed distributions in all the scenarios studied. Meanwhile, the distribution of burst sizes decays exponentially; this can be linked to a constant probability of finding a long-lasting clog during the evacuation process. Based on these results, a discussion is presented on the caution that should be exercised when measuring or describing the intermittent flow of pedestrians through narrow doors.

DOORS syndrome: phenotype, genotype and comparison with Coffin-Siris syndrome.
Campeau, Philippe M; Hennekam, Raoul C
2014-09-01
DOORS syndrome (Deafness, Onychodystrophy, Osteodystrophy, mental Retardation, Seizures) is characterized mainly by sensorineural deafness, shortened terminal phalanges with small nails of hands and feet, intellectual deficiency, and seizures. Half of the patients with all clinical features have mutations in TBC1D24. We review here the manifestations of patients clinically diagnosed with DOORS syndrome. In this cohort of 32 families (36 patients) we detected 13 individuals from 10 families with TBC1D24 mutations. Subsequent whole exome sequencing in the cohort showed the same de novoSMARCB1 mutation (c.1130G>A), known to cause Coffin-Siris syndrome, in two patients. Distinguishing features include retinal anomalies, Dandy-Walker malformation, scoliosis, rocker bottom feet, respiratory difficulties and absence of seizures, and 2-oxoglutaric aciduria in the patients with the SMARCB1 mutation. We briefly discuss the heterogeneity of the DOORS syndrome phenotype and the differential diagnosis of this condition. © 2014 Wiley Periodicals, Inc.

The Romanesque Bronze Doors at Gniezno Cathedral Church: Some New Remarks
Directory of Open Access Journals (Sweden)

2017-06-01
Full Text Available Among many Romanesque bronze doors in Europe the old entrance doors of the metropolitan cathedral in Gniezno, in the North Poland, are exceptional. For over a century many historians and historians of art have been trying to understand and explain its iconographic phenomenon. The Polish, Czech and German scholars have so far been unable to identify with any conviction, either the iconographic models or artistic provenance of the workshop. There were suggested some connections of the alleged bishop patrons to France and there were emphasizes technological possibilities of foundry workshops at the Meuse Valley. This “Meuse hypothesis” based mainly on historical suggestions became established as a certainty. However, it is important to emphasize the significant difference between the creator of the composition and of the craftsman who cast the bronze door. Years ago only Lech Kalinowski pointed out some general formal similarities to the North Italian sculpture. The purpose of this paper is to develop Kalinowski’s suggestions and to emphasise the puzzling similarities between details of Gniezno doors and some Emilian works executed by Master Wiligelmo da Modena and Master Nicolò. The concept of Italian relationship from Emilia province seems to be better for the comparative analysis than relationship with Meuse Valley based mostly on historical context. Crucial here is the additional, parallel analysis of the portal decoration in Czerwinsk Abbey.

Behaviour and design considerations for continuous flow closed-open-closed liquid microchannels.
Melin, Jessica; van der Wijngaart, Wouter; Stemme, Göran
2005-06-01
This paper introduces a method of combining open and closed microchannels in a single component in a novel way which couples the benefits of both open and closed microfluidic systems and introduces interesting on-chip microfluidic behaviour. Fluid behaviour in such a component, based on continuous pressure driven flow and surface tension, is discussed in terms of cross sectional flow behaviour, robustness, flow-pressure performance, and its application to microfluidic interfacing. The closed-open-closed microchannel possesses the versatility of upstream and downstream closed microfluidics along with open fluidic direct access. The device has the advantage of eliminating gas bubbles present upstream when these enter the open channel section. The unique behaviour of this device opens the door to applications including direct liquid sample interfacing without the need for additional and bulky sample tubing.

One of the most complicated parts of a car is the door. An so it will be in the future. More and more parts will be integrated in a car`s door, especially safety and comfort related parts as well as a big number of functional elements. The car industry tries intensively to bring about a growing safety image to its buyers. At the Institute for Technical Production and Logistics (IPL) of the University of Kassel (GhK) a passenger door construction out of magnesium has been developed on the base of a foregoing construction. With the new practice orientated model the time of production could be essentially reduced while at the same time the weight could be decreased. (orig.)

Clinical trials that compare strategies to optimize antibiotic use are of critical importance but are limited by competing risks that distort outcome interpretation, complexities of noninferiority trials, large sample sizes, and inadequate evaluation of benefits and harms at the patient level. The Antibacterial Resistance Leadership Group strives to overcome these challenges through innovative trial design. Response adjusted for duration of antibiotic risk (RADAR) is a novel methodology utilizing a superiority design and a 2-step process: (1) categorizing patients into an overall clinical outcome (based on benefits and harms), and (2) ranking patients with respect to a desirability of outcome ranking (DOOR). DOORs are constructed by assigning higher ranks to patients with (1) better overall clinical outcomes and (2) shorter durations of antibiotic use for similar overall clinical outcomes. DOOR distributions are compared between antibiotic use strategies. The probability that a randomly selected patient will have a better DOOR if assigned to the new strategy is estimated. DOOR/RADAR represents a new paradigm in assessing the risks and benefits of new strategies to optimize antibiotic use. © The Author 2015.

Full Text Available Wheeled Mobile Robots find numerous applications in the Indoor man made structured environments. In order to operate effectively, the robots must be capable of sensing its surroundings. Computer Vision is one of the prime research areas directed towards achieving these sensing capabilities. In this paper, we present a Door Sensing Mobile Robot capable of navigating in the indoor environment. A robust and inexpensive approach for recognition and classification of the door, based on monocular vision system helps the mobile robot in decision making. To prove the efficacy of the algorithm we have designed and developed a ‘Differentially’ Driven Mobile Robot. A wall following behavior using Ultra Sonic range sensors is employed by the mobile robot for navigation in the corridors. Field Programmable Gate Arrays (FPGA have been used for the implementation of PD Controller for wall following and PID Controller to control the speed of the Geared DC Motor.

Full Text Available This paper presents an innovative access control system, based on human detection and path analysis, to reduce false automatic door system actions while increasing the added values for security applications. The proposed system can first identify a person from the scene, and track his trajectory to predict his intention for accessing the entrance, and finally activate the door accordingly. The experimental results show that the proposed system has the advantages of high precision, safety, reliability, and can be responsive to demands, while preserving the benefits of being low cost and high added value.

This study addressed the effects of vehicle height mismatch in side impact crashes. A light truck or SUV tends to strike the door of a passenger car higher causing the upper border to lead into the occupant space. Conversely, an impact centered lower on the door, from a passenger car, causes the lower border to lead. We proposed the hypothesis that the type of injury sustained by the occupant could be related to door orientation during its intrusion into the passenger compartment. Data on door orientation and nearside occupant injuries were collected from 125 side impact crashes reported in the CIREN database. Experimental testing was performed using a pendulum carrying a frame and a vehicle door, impacting against a USDOT SID. The frame allowed the door orientation to be changed. A model was developed in MADYMO (v 6.2) using the more biofidelic dummies, BIOSID, and SIDIIs as well as USDOT SID. In side impact crashes with the lower border of the door leading, 81% of occupants sustained pelvic injury, 42% suffered rib fractures, and the rate of organ injury was 0.84. With the upper border leading, 46% of occupants sustained pelvic injury, 71% sustained rib fracture, and the rate of organ injuries per case increased to 1.13. The differences in the groups with respect to pelvic injury were significant at p = 0.01, rib fracture, p = 0.10, and organ injury, p = 0.001. Experimental testing showed that when the door angle changed from lower to upper border leading, peak T4 acceleration increased by 273% and pelvic acceleration decreased by 44%. The model demonstrated that when the door angle changed from lower to upper border leading, the USDOT SID showed a 29% increase in T4 acceleration and a 57% decrease in pelvic acceleration. The BIOSID dummy demonstrated a 36% increase in T1 acceleration, a 44% increase in abdominal rib 1 deflection, a 91% increase in thoracic rib 1 deflection, and a 33% decrease in pelvic acceleration. These data add more insight to the problem of
Predatory Publishing: How to Safely Navigate the Waters of Open Access.
Power, Helen
2018-03-01
Open access publishing enables scholarship to be openly accessible to everyone, which has countless benefits. However, the open access movement has opened the door for "predatory publishers" to take advantage of researchers surviving in this publish or perish academic landscape. Predatory journals are becoming increasingly common. Nursing researchers, instructors, and students need to be made aware of the dangers of predatory journals, and they need to know how to identify them. While there are blacklists and whitelists that can be used to aid in decision-making, it is critical to note that these lists can never be entirely up to date. This article incorporates a literature review which provides insights into newer trends in predatory and unethical publishing, including "journal hijacking" and "bogus impact factors". Extensive criteria for assessing emerging or unknown journals is compiled to aid researchers, students, educators, and the public in evaluating open access publications.

The new low energy electron beam accelerator bunker was designed and built locally to allocate a 500 keV electron beam accelerator at Block 43T in Malaysian Nuclear Agency. This bunker is equipped with a locally made radiation shielding door of 10 tons. Originally, this door is moving manually by a wheel and fitted with a gear system. However, it is still heavy and need longer time to operate it manually. To overcome those issues, a new automated control system has been designed and developed. In this paper, the complete steps and design of automated control system based on the microcontroller (PIC16F84A) is described.

Destructive spondyloarthropathy (DSA) is one of the major complications in patients undergoing long-term hemodialysis. To the best of our knowledge, an epidural abscess occurring at the level of preexisting cervical DSA has not been well described in the literature. We report a unique case of quadriplegia caused by an epidural abscess occurring at the same level of preexisting cervical DSA. A 49-year-old woman was transferred to our emergency department with 5 days of sepsis, drowsy mental status, and quadriplegia below the C5 level. The patient had a medical history of hemodialysis for 10 years. Magnetic resonance imaging showed spinal cord compression by an epidural abscess at the level of preexisting cervical DSA. Blood culture revealed methicillin-sensitive Staphylococcus aureus. Infection of the arteriovenous (AV) shunt was considered as the primary focus of sepsis and pyogenic spondylitis. We performed an emergent open door laminoplasty and the vascular team debrided the infected AV shunt site. Approximately 8 months after surgery, the patient was able to perform activities of daily living somewhat independently. Emergent surgical decompression and intensive medical care led to successful recovery from a septic and quadriplegic state in this patient. When diagnosing a patient who has undergone long-term hemodialysis presenting with neurologic deficits, the possibility of infectious spondylitis at the same level as DSA should be considered.
Technology collaboration by means of an open source government
Berardi, Steven M.
2009-05-01
The idea of open source software originally began in the early 1980s, but it never gained widespread support until recently, largely due to the explosive growth of the Internet. Only the Internet has made this kind of concept possible, bringing together millions of software developers from around the world to pool their knowledge. The tremendous success of open source software has prompted many corporations to adopt the culture of open source and thus share information they previously held secret. The government, and specifically the Department of Defense (DoD), could also benefit from adopting an open source culture. In acquiring satellite systems, the DoD often builds walls between program offices, but installing doors between programs can promote collaboration and information sharing. This paper addresses the challenges and consequences of adopting an open source culture to facilitate technology collaboration for DoD space acquisitions.

Early thrombolysis with fibrinolytic therapy has reduced mortality following acute myocardial infarction (AMI) with the major effect coming from early achievement of infarct-related artery potency. This study was carried out to determine the door-to-needle time in patients undergoing fibrinolytic therapy after acute myocardial infarction and to identify factors associated with a prolonged door-to-needle time. This was a cross sectional study in which patients who were thrombolysed for AMI with streptokinase at Punjab Institute of Cardiology, Lahore, from December 12, 2008 to February 18, 2009 were included. All patients admitted with AMI, who were candidates for fibrinolysis, were included. The time of infarction and time of arrival in hospital was determined with ECG changes and asking from patient and/or relatives. The reasons for delay of arrival were asked from patient and accompanying attendants where possible. A door-to-needle time of <30 min could be achieved in 110 of our 201 patients (54.72%). Mean door-to-needle time was 55.13 (+-71.04) minutes. A door-to-needle time of less than 30 minutes in 54.72% is comparable to most contemporary studies however there is a need to look into factors associated with delay. (author)
External debt and capital flight in Nigeria: Is there a revolving door?
Directory of Open Access Journals (Sweden)
OT Ajilore
2014-10-01
Full Text Available Using the residual method of capital flight estimation, this paper estimates Nigerian capital flight over the period 1970 - 2001 and finds a close correlation between external debt and capital flight flows. This phenomenon suggests a paradoxical revolving door of a bi-directional flow of capital, i.e. where capital enters the country in the guise of external borrowing and simultaneously slips out of the country as private capital flight. The research question addressed by this paper is whether such a financial revolving door relationship exists in Nigeria, just as previous empirical researches had established in a number of countries. The paper utilises a simultaneous equation model and three stage least square estimation technique (3SLS, in addition to two-way Granger causality tests, to obtain statistical evidence that confirms the existence of a financial revolving door relationship between the two endogenous variables. In addition, existence of stronger causality from debt to capital flight is instrumental in showing that growing public deficit and the resulting increase in external debt is being used as a transfer mechanism for capital flight.

Measuring Modularity in Open Source Code Bases
Directory of Open Access Journals (Sweden)
Roberto Milev
2009-03-01
Full Text Available Modularity of an open source software code base has been associated with growth of the software development community, the incentives for voluntary code contribution, and a reduction in the number of users who take code without contributing back to the community. As a theoretical construct, modularity links OSS to other domains of research, including organization theory, the economics of industry structure, and new product development. However, measuring the modularity of an OSS design has proven difficult, especially for large and complex systems. In this article, we describe some preliminary results of recent research at Carleton University that examines the evolving modularity of large-scale software systems. We describe a measurement method and a new modularity metric for comparing code bases of different size, introduce an open source toolkit that implements this method and metric, and provide an analysis of the evolution of the Apache Tomcat application server as an illustrative example of the insights gained from this approach. Although these results are preliminary, they open the door to further cross-discipline research that quantitatively links the concerns of business managers, entrepreneurs, policy-makers, and open source software developers.

Full Text Available The objective of this paper is to examine and identify barriers to and enablers for the European rail freight transport services as a transport chain partner along the supply chains in the changing market scenario. The changing market scenario includes, among others, requiring 'door-to-door' rather than 'terminal to terminal' and integrated service, competitive ability to attract non-rail cargo type, changes in the customer requirements (e.g. reliable service and changes in the operational requirements and practices. Using a literature review method, the paper is presented in two parts. The part 1 focuses on the identification of barriers to the European rail freight service by reviewing freight logistics services for global supply chains followed by the current performance of European rail freight transport followed by a discussion on the rail freight market liberalisation in Europe. Then rail freight transport in the Unites States (U.S. is discussed. The research notes that although the background, scope and necessity for reform measures in Europe differ from those of the U.S., some lessons can be learned and the main lesson is that an appropriate reform measure can enhance rail sector competitive ability in Europe. Examining and identifying the barriers in the part 1 (with the pan-Pacific examples of rail freight transports, the part 2 of the paper focuses on recommending clear actions and steps as enablers for the rail freight industry in general and operators in particular. The research in part 1 of the paper finds that: •\tIn many European countries, the rail freight market is not fully liberalised. In such market segment, infrastructure managers do act independently for incumbents and new entrant operators that hamper the progress of building a competitive market; •\tThe rail operators have not yet achieved the service quality (e.g. customer tailored service needed for the modern supply chains; •\tThey operate

Full Text Available Abstract Introduction Potential health damage by environmental emission of tobacco smoke (environmental tobacco smoke, ETS has been demonstrated convincingly in numerous studies. People, especially children, are still exposed to ETS in the small space of private cars. Although major amounts of toxic compounds from ETS are likely transported into the distal lung via particulate matter (PM, few studies have quantified the amount of PM in ETS. Study aim The aim of this study was to determine the ETS-dependent concentration of PM from both a 3R4F reference cigarette (RC as well as a Marlboro Red brand cigarette (MRC in a small enclosed space under different conditions of ventilation to model car exposure. Method In order to create ETS reproducibly, an emitter (ETSE was constructed and mounted on to an outdoor telephone booth with an inner volume of 1.75 m3. Cigarettes were smoked under open- and closed-door condition to imitate different ventilation scenarios. PM2.5 concentration was quantified by a laser aerosol spectrometer (Grimm; Model 1.109, and data were adjusted for baseline values. Simultaneously indoor and outdoor climate parameters were recorded. The time of smoking was divided into the ETS generation phase (subset “emission” and a declining phase of PM concentration (subset “elimination”; measurement was terminated after 10 min. For all three time periods the average concentration of PM2.5 (Cmean-PM2.5 and the area under the PM2.5 concentration curve (AUC-PM2.5 was calculated. The maximum concentration (Cmax-PM2.5 was taken from the total interval. Results For both cigarette types open-door ventilation reduced the AUC-PM2.5 (RC: from 59 400 ± 14 600 to 5 550 ± 3 900 μg*sec/m3; MRC: from 86 500 ± 32 000 to 7 300 ± 2 400 μg*sec/m3; p mean-PM2.5 (RC: from 600 ± 150 to 56 ± 40 μg/m3, MRC from 870 ± 320 to 75 ± 25 μg/m3; p max-PM2.5 was reduced by about 80% (RC: from 1 050 ± 230 to
3D Modeling of Building Indoor Spaces and Closed Doors from Imagery and Point Clouds

Full Text Available 3D models of indoor environments are increasingly gaining importance due to the wide range of applications to which they can be subjected: from redesign and visualization to monitoring and simulation. These models usually exist only for newly constructed buildings; therefore, the development of automatic approaches for reconstructing 3D indoors from imagery and/or point clouds can make the process easier, faster and cheaper. Among the constructive elements defining a building interior, doors are very common elements and their detection can be very useful either for knowing the environment structure, to perform an efficient navigation or to plan appropriate evacuation routes. The fact that doors are topologically connected to walls by being coplanar, together with the unavoidable presence of clutter and occlusions indoors, increases the inherent complexity of the automation of the recognition process. In this work, we present a pipeline of techniques used for the reconstruction and interpretation of building interiors based on point clouds and images. The methodology analyses the visibility problem of indoor environments and goes in depth with door candidate detection. The presented approach is tested in real data sets showing its potential with a high door detection rate and applicability for robust and efficient envelope reconstruction.

Full Text Available Online trade of CITES listed species has become a persistent threat which is difficult to measure and control. The use of online markets is growing day by the day as technology becomes more available and familiar to people of all ages and interests. Species trade can now be propagated remotely hardly without any real human interaction. We develop a quick-easy method to assess the online availability of the genus Strombocactus, a highly collectible cactus, to understand the real magnitude of this new form of threat and the possible menace it could be for these Mexican cacti. We used the Google.com site to do an online search in four languages (Spanish, English, French and German for the offer of adult plants or seeds. We found specimens and seeds available in major online markets like ebay, amazon, cactusplaza.com and mercado libre. Plant price range from €10.00 to €30.00 plus shipping and handling. The plants were also offered in local online stores in countries like the USA, France, Germany, Australia, Czech Republic, the United Kingdom, and others; some sellers claim they have no obstacles for “shipping across countries” and others openly declare the natural localities where seeds were extracted. Only a minority of these online stores openly stated that the cacti were obtained from CITES registered nurseries or that the cacti were grown through propagules or seeds. Our method is easily transferable to estimate the illegal market for any species. There is an active online trade of Strombocactus species and other species listed in CITES without the necessary documentation. Compliance or other regulation mechanisms are needed in order to promote species conservation.
Inflatable door seals - reduced maintenance and longer service-life

1995-01-01
Inflatable door seals, designed more than a quarter of a century ago, have given good service in Canadian and overseas CANDU reactors. These thin-walled elastomeric seals have been exposed to many thousands of cycles of inflation and deflation, various types of aging (temperature, radiation and time), ozone degradation, abrasion, pinching, stiction, cracking and installation damage. The fact that they have operated successfully as part of the reactor building containment structure - subjected to the same pressures and temperatures as those for the thick reinforced concrete walls and steel doors highlights the achievement of these thin rubber seals. However, in the last decade, the rubber industry has developed new compounds that are more resistant to radiation, temperature, and time-dependent aging. Components manufactured from such compounds are less prone to hardening, stress cracking and permanent set; thereby saving on replacement costs, inventory and overall maintenance. This paper discusses development and testing of recent material and design changes to inflatable seals, and addresses various practical issues faced by the operations engineers and maintainers using these seals.

Westinghouse Safety Management Solutions (Westinghouse SMS) has been tasked with providing radiological engineering design support for the new Commercial Light Water Reactor Tritium Extraction Facility (CLWR-TEF) being constructed at the Savannah River Site (SRS). The Remote Handling Building (RHB) of the CLWR-TEF will act as the receiving facility for irradiated targets used in the production of tritium for the U.S. Department of Energy (DOE). Because of the high dose rates, approaching 50 000 rads/h (500 Gy/h) from the irradiated target bundles, significant attention has been made to shielding structures within the facility. One aspect of the design that has undergone intense review is the shield doors. The RHB has six shield doors that needed to be studied with respect to photon streaming. Several aspects had to be examined to ensure that the design meets the radiation dose levels. Both the thickness and streaming issues around the door edges were designed and examined. Photon streaming through and around a shield door is a complicated problem, creating a reliance on computer modeling to perform the analyses. The computer code typically used by the Westinghouse SMS in the evaluation of photon transport through complex geometries is the MCNP Monte Carlo computer code. The complexity of the geometry within the problem can cause problems even with the Monte Carlo codes. Striking a balance between how the code handles transport through the shield door with transport through the streaming paths, particularly with the use of typical variance reduction methods, is difficult when trying to ensure that all important regions of the model are sampled appropriately. The thickness determination used a simple variance reduction technique. In construction, the shield door will not be flush against the wall, so a solid rectangular slab leaves streaming paths around the edges. Administrative controls could be used to control dose to workers; however, 10 CFR 835.1001 states

Door and window image-based measurement using a mobile device
Ma, Guangyao; Janakaraj, Manishankar; Agam, Gady
2015-03-01
We present a system for door and window image-based measurement using an Android mobile device. In this system a user takes an image of a door or window that needs to be measured and using interaction measures specific dimensions of the object. The existing object is removed from the image and a 3D model of a replacement is rendered onto the image. The visualization provides a 3D model with which the user can interact. When tested on a mobile Android platform with an 8MP camera we obtain an average measurement error of roughly 0.5%. This error rate is stable across a range of view angles, distances from the object, and image resolutions. The main advantages of our mobile device application for image measurement include measuring objects for which physical access is not readily available, documenting in a precise manner the locations in the scene where the measurements were taken, and visualizing a new object with custom selections inside the original view.

Five-year experience with burns from glass fireplace doors in the pediatric population.
Baryza, Mary Jo; Hinson, Michelle; Conway, Jennifer; Ryan, Colleen M
2013-01-01
Burns from contact with glass doors of gas fireplaces have been previously reported. The purpose of this study is to examine the incidence and severity of this injury in our population. Patients were identified for inclusion in the retrospective chart review study using the National Trauma Registry of the American College of Surgeons (NTRACS) and our local outpatient database. Criteria for inclusion were burn injuries sustained from contact with fireplace glass doors treated at our pediatric burn center from 2007 through 2011. Fifty children met these criteria, including two children whose burns were caused by electric fireplace glass doors. BSA burned was 1.5 ± 1.5% (mean ± SD), range 0.5 to 10%. Age was 27.2 ± 27.3 months, range 8 months to 13 years. Forty-five children (90%) had hand burns; of these, 18 children had bilateral hand involvement. Facial burns were found in three children (6%), and eight children (16%) had other areas burned. One patient developed cellulitis. Two patients required surgery. Six children (12%) required hospitalization; mean length of stay was 5.8 ± 5 days, range 1 to 5 days. Although the number of inpatient admissions was relatively few, 329 outpatient visits and 309 rehabilitation visits were required for treatment of these children. Nineteen patients (38%) required splints and six patients (12%) required scar treatment with pressure garments. Burns from contact with fireplace glass doors are a recurring problem. Toddlers are most at risk. Directed preventive strategies including parent education, safety warnings, and design modifications such as temperature sensors and barrier screens could be potentially helpful in reducing the incidence of this injury.

Blower door method in radon diagnostics
International Nuclear Information System (INIS)
Fronka, A.; Moucka, L.
2004-01-01
The idea of the radon transfer factor is commonly presented as the ratio of the building indoor radon concentration to the subsoil radon concentration. Ventilation and the pressure field over the whole building envelope, which varies in a time over a very wide range even in the same building, poses a major problem. Therefore a new approach based on the controlled conditions determining the soil air infiltration was developed. Radon in soil gas infiltrates into the building indoor environment particularly through cracks and other leakages in the structure providing the building contact with its subsoil. The infiltration is driven by the air pressure difference on the two sides of the structure. The pressure difference is caused by the stack effect and its value ranges from 1-2 Pa in family houses to some tens of Pa in higher buildings. Unfortunately, the pressure difference is very unstable under normal conditions, being affected by a host of parameters such as the height of the building, distribution and geometry of leakages, outdoor-indoor temperature difference, etc. Wind direction and velocity of the wind plays a major role. In our research the blower door method was applied in combination with a monitoring of the indoor radon concentration. The indoor-outdoor pressure difference and the pressure difference at the two sides of the screen shutter of the blower door fan are also measured. The blower door ensures a constant, evaluable air exchange rate. The fan power is regulated to provide a stable pressure difference within the range of roughly 5-100 Pa. This approach provides very well defined conditions allowing us to apply a constant ventilation-constant radon supply model. In such circumstances the dynamical changes of radon concentrations are very fast, and therefore a unique continual radon monitor was applied. The radon supply rate is evaluated from the radon steady state of the time course of radon concentration. The dependence of the radon supply rate on

Looking for the WIMP next door
Evans, Jared A.; Gori, Stefania; Shelton, Jessie
2018-02-01
We comprehensively study experimental constraints and prospects for a class of minimal hidden sector dark matter (DM) models, highlighting how the cosmological history of these models informs the experimental signals. We study simple `secluded' models, where the DM freezes out into unstable dark mediator states, and consider the minimal cosmic history of this dark sector, where coupling of the dark mediator to the SM was sufficient to keep the two sectors in thermal equilibrium at early times. In the well-motivated case where the dark mediators couple to the Standard Model (SM) via renormalizable interactions, the requirement of thermal equilibrium provides a minimal, UV-insensitive, and predictive cosmology for hidden sector dark matter. We call DM that freezes out of a dark radiation bath in thermal equilibrium with the SM a WIMP next door, and demonstrate that the parameter space for such WIMPs next door is sharply defined, bounded, and in large part potentially accessible. This parameter space, and the corresponding signals, depend on the leading interaction between the SM and the dark mediator; we establish it for both Higgs and vector portal interactions. In particular, there is a cosmological lower bound on the portal coupling strength necessary to thermalize the two sectors in the early universe. We determine this thermalization floor as a function of equilibration temperature for the first time. We demonstrate that direct detection experiments are currently probing this cosmological lower bound in some regions of parameter space, while indirect detection signals and terrestrial searches for the mediator cut further into the viable parameter space. We present regions of interest for both direct detection and dark mediator searches, including motivated parameter space for the direct detection of sub-GeV DM.

The detailed analysis of nuclear reactions occurring in materials of the door is presented for the typical construction of an entrance door to a room with a slowed down neutron field. The changes in the construction of the door were determined to reduce effectively the level of neutron and gamma radiation in the vicinity of the door in a room adjoining the neutron field room. Optimisation of the door construction was performed with the use of Monte Carlo calculations (GEANT4). The construction proposed in this paper bases on the commonly used inexpensive protective materials such as borax (13.4 cm), lead (4 cm) and stainless steel (0.1 and 0.5 cm on the side of the neutron field room and of the adjoining room, respectively). The improved construction of the door, worked out in the presented studies, can be an effective protection against neutrons with energies up to 1 MeV (authors)

Cast magnesium side door inner panels can provide a good combination of weight, functional, manufacturing and economical requirements. However, several challenges exist including casting technology for thin-wall part design, multi-material incompatibility and relatively low strength vs steel. A project has been initiated, supported by the US Department of Energy, to design and develop a lightweight frame-under-glass door having a thin-wall, full die-cast, magnesium inner panel. This development project is the first of its kind within North America. Phase I of the project is now complete and the 2.0mm magnesium design, through casting process enablers, has met or exceeded all stiffness requirements, with significant mass reduction and part consolidation. In addition, a corrosion mitigation strategy has been established using industry-accepted galvanic isolation methods and coating technologies.

The huge socioeconomic burden of parkinsonism necessitates the need for prevalence studies in each country. So far, there is neither data registry nor prevalence information on parkinsonism in the Iranian population. The aim of our study was to estimate the prevalence rate of probable parkinsonism in a huge urban area in Iran, Tehran using a community-based door-to-door survey.Materials and methods: We used a random multistage sampling of the households within the network of health centers consisting of 374 subunits in all 22 districts throughout the entire urban area of Tehran. Overall, 20,621 individuals answered the baseline checklist and screening questionnaire and data from 19,500 persons aged ≥30 years were entered in the final analysis. Health care professionals used a new six-item screening questionnaire for parkinsonism, which has been previously shown to have a high validity and diagnostic value in the same population.Results: A total of 157 cases were screened for parkinsonism using the validated six-item questionnaire.

Reinforced concrete (RC) frame structures with brick-masonry infills are commonly used in developing countries and high-risk seismic area, such as Indonesia. Significant researches have been carried out for studying the seismic performance of RC frame structures with brick-masonry infills. Only few of them focused on effects of the opening in the brick-masonry infill to the seismic performance of the RC frame structures. The presence of opening in brick-masonry infill is often used for placing doors and windows as well, however, it may reduce the seismic performance of the RC frame structure. In the current study, they influence of the opening in brick-masonry infills to the seismic performance RC frame structure will experimentally evaluated. Five of 1/4-scaled single story and single bay RC frame specimens were prepared, i.e. an RC bare frame, a clay brick-masonry infilled RC frame and three of clay brick-masonry infilled RC frame with openings in the brick-masonry infills. The last three specimens were clay brick infilled RC frame with a center opening, clay brick infilled RC frame with two openings used for placing the windows and clay brick infilled RC frame with opening for placing the door. The specimens pushed over by applying the static monotonic lateral load to the upper beam of the RC frame structures. The incremental of the lateral load and the lateral displacement of RC frame's column was recorded during test. The crack propagation and the major cracks were also observed to identify the mechanism failure of specimens. As the results, the opening in the brick-masonry wall controls the failure mechanism, the lateral strength and the stiffness of the overall of infilled RC frame structure. The diagonal shear crack pattern was found on brick-masonry wall without opening, on other hand the different crack patterns were observed on brick-masonry wall with openings. Although the opening in the brick masonry infill reduced the lateral strength and stiffness of

2018-02-01
Sandia National Laboratories/CA (SNL/CA) operates 14 diesel vehicles subject to the Off-Road Diesel Equipment Regulation; all the vehicles are classified as low-use vehicles. Annually, SNL/CA must report to the CA Air Resources Board (ARB) the hour-meter readings on our Off-Road Low-Use Diesel Equipment. This is to verify to the CA ARB that our equipment is being operated less than 200 hr/yr and therefore is considered “low-use” and not subject to the strict emissions standards for off-road diesel equipment. The reporting is done using DOORS, the CA ARB’s on-line reporting tool. The hour meter data for CY2017 has already been submitted using DOORS. The final step in the annual reporting process, which needs to be done by DOE, is to submit the Responsible Official Affirmation of Reporting (ROAR), which affirms that the information reported using DOORS is accurate. The ROAR is to be signed by a “Responsible Official” and can be submitted as a hardcopy ROAR or an electronic ROAR (e-ROAR) by March 1st, 2018. CA ARB’s preferred mechanism of ROAR submission is by using the e-ROAR.
How open innovation can help you cope in lean times.
Chesbrough, Henry W; Garman, Andrew R
2009-12-01
A recession often forces you to cut R&D as you refocus on your core. But innovation need not go by the wayside. By placing certain assets and projects outside your walls, you can actually preserve opportunities for future growth while you shore up the fortress. Chesbrough, of Haas School of Business, and Garman, of New Venture Partners, identify five strategic moves that open the door to innovation by, ironically, letting it out of the house. Some inside-out moves permit outside firms to invest in and develop your projects; others call for spinning off projects as separate ventures that still allow you to retain some equity. Whatever the specific approach, you can meet the inherent cultural and organizational challenges of inside-out open innovation by approaching it holistically and placing it under the leadership of senior executives in strategic roles.

Construction and testing of a blower-door assembly for regulation of air pressure within structures
International Nuclear Information System (INIS)
Steele, W.D.
1987-09-01
The Technical Measurements Center is evaluating several methods to decrease the time required to determine an annual average radon-daughter concentration in structures. One method involves stabilizing the air pressure within the structure at a constant pressure with reference to external atmospheric or soil-gas pressure. This report describes the construction and preliminary testing of a blower-door system to maintain a constant differential air pressure within a structure. The blower-door assembly includes a collapsible frame and a large fan to occlude a doorway, a damper with an actuator to control air flow, a controller to drive the damper actuator, and a pressure transducer to measure the differential pressure. Preliminary testing of the system indicates that pressure within the structure in the range of 1 to 20 Pascals can be held to within approximately +-1 Pa of the set point. Further testing of the blower-door system is planned to provide data on the applicability of this method to short-duration tests for annual average radon-daughter concentration estimates. 13 figs., 1 tab

The water film is generated at the roller box of the high-speed roller door in this study. The heating test is done with the full-scale heating furnace. Both cases of the water film on unexposed surface and water film on exposed surface passed the fire resistance test based on ISO 834, proving that the high-speed roller door with water film system has 120A fire resistance period. The main findings indicate that the water film on exposed surface shows that as the amount of water film evaporated by high temperature inside the furnace must be greater than the evaporation capacity of water film on unexposed surface, the required water supply is 660 L more than the water film on unexposed surface.
"On the gate of Arctic": Doors open to foreign schools
Pecchiar, Irene
2015-04-01
With the increased attention to the changing of the Arctic Region as a consequence of global climate changes, effective science education, outreach and communication need to be higher priorities within the scientific communities. In order to encourage the dissemination of polar research at educational levels Slovene high school students in Trieste were first engaged at school and at the National Museum of Antarctica of Trieste using conferences and laboratory activities to introduce the main polar climate change topics. Then together with three teachers they visited Tromso University (North Norway) for a week. The first aim of this project was to increase awareness of foreign schools on major topics concerning the Arctic issues (from the economic/social to the environmental/climatic point of view). Forty-three high school students were involved in the laboratory activities running at the University of Tromso and participated in seminars. The topics focused on were Ocean Acidification, Global Warming and the combined effects with other anthropogenic stressors. During their stay, students interviewed several scientists in order to allow them to edit a »visiting report«, that was updated every day in their blog and to elaborate all the material collected (photos, videos, data of laboratory work, reports). In Tromso, they were also introduced to the culture and tradition of the Scandinavian indigenous people at the Center of Sami Study. Back in Italy, they published some articles in local newspapers, and then they presented their results at the National Museum of Antarctica of Trieste about all the data elaboration in an open day exhibition with posters, short movies and PowerPoint presentations. All this work was made in order to pass their experience into the world. This was a pilot project, highlighting the role of universities as links between research and outreach. The next step should be to enlarge these kinds of activities to many Schools, Universities and
Openness to the unexpected: Our Pathways to Careers in a Federal Research Laboratory.
Newman, Kurt R.; Bunnell, David B.; Hondorp, Darryl W.; Taylor, William W.; Lynch, Abigail J.; Léonard, Nancy J.
2014-01-01
Many fisheries professionals may not be in the job they originally envisioned for themselves when they began their undergraduate studies. Rather, their current positions could be the result of unexpected, opportunistic, or perhaps even “lucky” open doors that led them down an unexpected path. In many cases, a mentor helped facilitate the unforeseen trajectory. We offer three unique stories about joining a federal fisheries research laboratory, from the perspective of a scientist, a joint manager-scientist, and a manager. We also use our various experiences to form recommendations that should help the next generation of fisheries professionals succeed in any stop along their journey, including being open to opportunities, setting high expectations, and finding a strong and supportive team environment to work in.

From PAWP to "Pop": opening up new pathways to fatherhood.
Vadnais, Melissa L; Gerton, George L
2015-01-01
Infertility remains a significant problem for many couples. Approximately one in seven couples who attempt to conceive will fail to do so within 1 year. In about 65% of these cases, there is a male component of infertility.1 Despite normal semen parameters, the etiology of infertility remains uncertain in more than 50% of couples.2 Defects in sperm proteins and/ or structures may underlie certain cases of male infertility. Although many men would like to be called "Pop", "Dad", or "Papa", those who are classified with idiopathic male infertility have few options for becoming fathers. Recent studies by Aarabi et al.3 may open the door to new therapies.

Sethna, H.N.
1985-01-01
The author discusses how the Atoms for Peace speech heralded the birth of an era of cooperation between the sovereign nations of the world in the peaceful uses of atomic energy for the benefit of all mankind. He explains how India imported the technology it needed to implement its own nuclear power program. India not only assimilated this imported technology completely, but also adapted it to its own conditions and requirements. Action was also taken to diversify, improve and scale up the technology so as to be independent of further imports. The author says that the initial cooperation agreement made by Eisenhower has been the bedrock on which India's nuclear program has been built
Opening doors to knowledge in Bhutan.
1994-01-01
School girls, teachers, and health school students were surveyed, using 3 different questionnaires, in January 1993. Catherine Payne, former research associate of the Family Planning Council of Southeastern Pennsylvania, visited Bhutan from August 18 through September 4, 1993, to assist with the interpretation of results and to interview teachers in schools where the new curriculum would be introduced and officials who were writing it. Results were released in October 1993. 160 young women (10-20 years of age) from 5 schools were surveyed and another 60 were interviewed by Payne. 25% of the surveyed girls understood the connection between menstruation and reproduction. Of those who had heard of menstruation, 60% had heard about it from their friends; 30%, from siblings; 27%, from mothers; and 10%, from schools. Teachers in the survey were supportive of the study and recognized the importance of reproductive health education. Also, officials of the education and health ministries, epidemiologists, experts in information, education, and communication (IEC), and district health officers attended a 2-day workshop directed at local data collection and analysis of this type. Although teenage pregnancy and sexually transmitted diseases (STDs) are increasing in Bhutan, family planning services are not reaching youth, particularly those who do not attend school or do not have children. Hospitals provide contraceptives mainly to those over 21, and outreach clinics are not catering to the family planning needs of minors. One of the recommendations of this survey/workshop was to provide correct information on reproductive health to youth.

Full Text Available Tall towers and multi-storey buildings have fascinated mankind from the beginning of civilization, their construction being initially for defense and subsequently for ecclesiastical purposes. These tall buildings because of its height, is affected by lateral forces due to wind or earthquake actions tends to snap the building in shear and push it over in bending. In general, the rigidity (i.e. Resistance to lateral deflection and stability (i.e. Resistance to overturning moments requirement become more important. Shear walls (Structural walls contribute significant lateral stiffness, strength, and overall ductility and energy dissipation capacity. In many structural walls a regular pattern of openings has to be provided due to various functional requirements such as to accommodate doors, windows and service ducts. Such type of openings reduces the stiffness of the shear wall to some extent depending on the shape and size of the opening. In the present parametric study, efforts are made to investigate and critically assess the effects of various size of openings in shear walls on the responses and behaviors of multi-storey buildings. The 30 storey Prototype buildings with different types of openings in shear wall with and without incorporating the volume of shear wall reduced in the boundary elements are analyzed using software E-TABS using Response spectrum method (1893(Part-1-2002 and Time history method.

Bossini, D.; Miglio, A.; Salaris, M.
2017-01-01
Convective mixing in helium-core-burning (HeCB) stars is one of the outstanding issues in stellar modelling. The precise asteroseismic measurements of gravity-mode period spacing (Delta Pi(1)) have opened the door to detailed studies of the near-core structure of such stars, which had not been...... possible before. Here, we provide stringent tests of various core-mixing scenarios against the largely unbiased population of red-clump stars belonging to the old-open clusters monitored by Kepler, and by coupling the updated precise inference on Delta Pi(1) in thousands of field stars with spectroscopic...... constraints. We find that models with moderate overshooting successfully reproduce the range observed of Delta Pi(1) in clusters. In particular, we show that there is no evidence for the need to extend the size of the adiabatically stratified core, at least at the beginning of the HeCB phase. This conclusion...

"Living alone with closed windows and doors"was mentioned in the pathological manifestations of stomach meridian of foot- yangming in Neijing ( The Inner Canon of Huangdi ), which is similar to the symptoms of depression. Currently the treatment of depression is mostly based on"spirit being stored in five organs"theory, and little attention is paid on stomach meridian of foot- yangming . From the pathological manifestations of"living alone with closed windows and doors"in stomach meridian of foot- yangming , the relationship between stomach meridian and depression is discussed from ying-yang and qi -blood. In addition, the close relationship between the stomach meridian and qi -blood, qi movement of five organs, heart and brain is discussed to explore the mechanism of treating depression. In conclusion, the literature and modern research regarding treating depression from stomach meridian are summarized, hoping to provide more clinical methods for the treatment of depression.

Doors and thresholds: Jeddi's approach to psychiatric disorders.
Devisch, R; Vervaeck, B
1986-01-01
Professor Essedik Jeddi and his team have introduced a most significant institutional and therapeutic innovation at the Ibn Rochd and Pinel section of the Razi university long-term mental hospital in Tunis (Tunisia). The innovation focuses upon the ambiguity of doors and boundaries in the mental asylum. Doors and walls influence the rhythm of activity and the nature of contact between patients, therapists and the wider society and culture. If they are very rigid, they may disjoin the patient from him- or herself, from his/her body, social network and culture. On the other hand, if such boundaries are completely neglected they may merge these related dimensions as undifferentiated entities. Jeddi's innovation is primarily concerned with placing the spatio-temporal experience of the body and the intimate interpersonal interaction at the centre of treatment. It aims at establishing creative modes of expression, interaction and exchange such as tea-sessions, dancing, singing, verbal communication, clay-modelling, figurative or plastic expression, agricultural works. These relationships mediate and differentiate at the same time between the patient, his/her body-self, and his/her social and cultural world, thus avoiding both the disjunction and the merging. It would seem that the activities concerned with the distinction between 'inside' and 'outside', peasant and urban, self and other (e.g. dancing and singing) are of paramount importance in bringing about such mediating and differentiating relationships. In the present study we limit ourselves to one particularly revealing therapeutic activity, namely dancing to live music. Jeddi's innovation is a unique blend of current developments in psychiatry and psychotherapy with Arabo-Islamic science and philosophy.

Current literature examining the relationship between door-opening rate, number of people present, and microbial air contamination in the operating room is limited. Studies are especially needed from low- and middle-income countries, where the risk of surgical site infections is high. To assess microbial air contamination in operating rooms at a Ghanaian teaching hospital and the association with door-openings and number of people present. Moreover, we aimed to document reasons for door-opening. We conducted active air-sampling using an MAS 100 ® portable impactor during 124 clean or clean-contaminated elective surgical procedures. The number of people present, door-opening rate and the reasons for each door-opening were recorded by direct observation using pretested structured observation forms. During surgery, the mean number of colony-forming units (cfu) was 328 cfu/m 3 air, and 429 (84%) of 510 samples exceeded a recommended level of 180 cfu/m 3 . Of 6717 door-openings recorded, 77% were considered unnecessary. Levels of cfu/m 3 were strongly correlated with the number of people present (P = 0.001) and with the number of door-openings/h (P = 0.02). In empty operating rooms, the mean cfu count was 39 cfu/m 3 after 1 h of uninterrupted ventilation and 52 (51%) of 102 samples exceeded a recommended level of 35 cfu/m 3 . The study revealed high values of intraoperative airborne cfu exceeding recommended levels. Minimizing the number of door-openings and people present during surgery could be an effective strategy to reduce microbial air contamination in low- and middle-income settings.

Full Text Available The key of realizing the cross docking is to design the joint of inbound trucks and outbound trucks, so a proper sequence of trucks will make the cross-docking system much more efficient and need less makespan. A cross-docking system is proposed with multiple receiving and shipping dock doors. The objective is to find the best door assignments and the sequences of trucks in the principle of products distribution to minimize the total makespan of cross docking. To solve the problem that is regarded as a mixed integer linear programming (MILP model, three metaheuristics, namely, harmony search (HS, improved harmony search (IHS, and genetic algorithm (GA, are proposed. Furthermore, the fixed parameters are optimized by Taguchi experiments to improve the accuracy of solutions further. Finally, several numerical examples are put forward to evaluate the performances of proposed algorithms.

Full Text Available This study compared building-related symptoms in personal and open plan offices, where high and low levels of control over the thermal environment were provided, respectively. The individualized approach in Norway provided every user with a personal office, where they had control over an openable window, door, blinds, and thermostat. In contrast, the open plan case studies in the United Kingdom provided control over openable windows and blinds only for limited occupants seated around the perimeter of the building, with users seated away from the windows having no means of environmental control. Air conditioning was deployed in the Norwegian case study buildings, while displacement ventilation and natural ventilation were utilized in the British examples. Field studies of thermal comfort were applied with questionnaires, environmental measurements, and interviews. Users’ health was better in the Norwegian model (28%, while the British model was much more energy efficient (up to 10 times. The follow-up interviews confirmed the effect of lack of thermal control on users’ health. A balanced appraisal was made of energy performance and users’ health between the two buildings.
The effect of a paraffin screen on the neutron dose at the maze door of a 15 MV linear accelerator.

2013-08-01
The purpose of this study was to explore the effects of a paraffin screen located at various positions in the maze on the neutron dose equivalent at the maze door. The neutron dose equivalent was measured at the maze door of a room containing a 15 MV linear accelerator for x-ray therapy. Measurements were performed for several positions of the paraffin screen covering only 27.5% of the cross-sectional area of the maze. The neutron dose equivalent was also measured at all screen positions. Two simple models of the neutron source were considered in which the first assumed that the source was the cross-sectional area at the inner entrance of the maze, radiating neutrons in an isotropic manner. In the second model the reduction in the neutron dose equivalent at the maze door due to the paraffin screen was considered to be a function of the mean values of the neutron fluence and energy at the screen. The results of this study indicate that the equivalent dose at the maze door was reduced by a factor of 3 through the use of a paraffin screen that was placed inside the maze. It was also determined that the contributions to the dosage from areas that were not covered by the paraffin screen as viewed from the dosimeter, were 2.5 times higher than the contributions from the covered areas. This study also concluded that the contributions of the maze walls, ceiling, and floor to the total neutron dose equivalent were an order of magnitude lower than those from the surface at the far end of the maze. This study demonstrated that a paraffin screen could be used to reduce the neutron dose equivalent at the maze door by a factor of 3. This paper also found that the reduction of the neutron dose equivalent was a linear function of the area covered by the maze screen and that the decrease in the dose at the maze door could be modeled as an exponential function of the product φ·E at the screen.

Northern Oil is moving offices, and CEO Fritz Schumacher wants to make the most of the move in this fictional case study. He believes that adopting an open-plan work space will reinvent how the company works, not to mention cut costs. Facilities manager Sasha Pasternak also supports the open plan. Her job would be easier, and her budget would stretch further, if Northern had standardized workstations and used partitions, not walls. And she likes the way the new design flattens the organization: everyone has the same amount of space and the same ergonomically sound furniture. The new building would have more conference rooms and just-in-time work spaces for employees who worked mostly off-site. And although she knew that initial meetings between the architects and Northern employees hadn't yielded much support for open space--people were attached to their private offices--she expected that people would warm to the idea. But when the new design was unveiled, employees were less than enthusiastic. They hurled questions like, How will workers concentrate if they can't shut their office doors? How will people have confidential meetings with their boss? And why would people stay at Northern when the competition offers them private offices? There was even talk of circulating a petition refusing to move to the new space. A week later, the architect presented revised plans to the project group. The new options would add costs and reduce the amount of space savings, but offering a choice to employees might make them feel less threatened. What should the project team do? Five commentators offer advice.

Several technologies can be applied to enable mobile location services, but most of them suffer from limited accuracy and availability. GPS can solve the problem of determining the location of users in most outdoor situations, but an end-user position inside a building cannot be pinpointed. Other...... mobile location techniques can also provide the user's position, but the accuracy is rather low. In order to improve the accuracy and make location-based services really attractive, existing approaches must be supplemented by new technologies. Wireless short-range technologies like Bluetooth could...... be candidates for solving these problems. This paper shows that Bluetooth can act as a key enabler of mobile location services in an in-door environment. The advantage of Bluetooth technology is, that it can provide rather precise location data inside a building or hotspot area, while the Bluetooth terminal...

Full Text Available The Precast Reinforced Concrete Wall Panel (PRCWP presented in this paper is part of an experimental study regarding the seismic performance of precast reinforced concrete wall panels, strengthening strategies and investigation on the weakening induced by modifying the opening in these elements due to architectural demands, change of function of buildings or other reasons. The element presented is 1:1.2 scale typical Reinforced Concrete Wall Panel with a window opening used in Romania, in which the opening was changed to a door opening due to comfort considerations. The specimen was subjected to cyclic loading with the lateral loads being applied in displacement control of 0.1% drift ratio. This simulates the shear behaviour of the element. After testing the unstrengthen element we proceed to retrofit it using Carbon Fibre Strips anchored with Carbon Fibre Mash. The purpose of the paper is to present the strengthening strategy and restore the initial load bearing capacity of the element or even increase it. The experimental results of strengthen and unstrengthen specimens will be presented.

Solar Power Ramp Events Detection Using an Optimized Swinging Door Algorithm: Preprint
Energy Technology Data Exchange (ETDEWEB)
Cui, Mingjian; Zhang, Jie; Florita, Anthony; Hodge, Bri-Mathias; Ke, Deping; Sun, Yuanzhang

Solar power ramp events (SPREs) are those that significantly influence the integration of solar power on non-clear days and threaten the reliable and economic operation of power systems. Accurately extracting solar power ramps becomes more important with increasing levels of solar power penetrations in power systems. In this paper, we develop an optimized swinging door algorithm (OpSDA) to detection. First, the swinging door algorithm (SDA) is utilized to segregate measured solar power generation into consecutive segments in a piecewise linear fashion. Then we use a dynamic programming approach to combine adjacent segments into significant ramps when the decision thresholds are met. In addition, the expected SPREs occurring in clear-sky solar power conditions are removed. Measured solar power data from Tucson Electric Power is used to assess the performance of the proposed methodology. OpSDA is compared to two other ramp detection methods: the SDA and the L1-Ramp Detect with Sliding Window (L1-SW) method. The statistical results show the validity and effectiveness of the proposed method. OpSDA can significantly improve the performance of the SDA, and it can perform as well as or better than L1-SW with substantially less computation time.
The Glass Door: The Gender Composition of Newly-Hired Workers Across Hierarchical Job Levels
Hassink, W.H.J.|info:eu-repo/dai/nl/090437411; Russo, G.|info:eu-repo/dai/nl/124883206
This paper examines the gender composition of the flow of new hirees along the organizational hierarchy of jobs. We find that women have a reduced chance to be hired at higher hierarchical levels. We refer to this phenomenon as the “glass door”. The glass door consists of an absolute and a relative
Open Day at Crèche and School of the CERN Staff Association

In the morning of Saturday, 3 March 2018, the Crèche and School of the CERN Staff Association opened its doors for parents who wished to visit the establishment. Once again, the Open Day was a great success and brought together more than 50 families for two information sessions, which included: a general presentation of the establishment by the Headmistress, and a visit of the facilities led by the Headmistress and her deputy. At the end of the visit, parents were invited for a drink. This was an opportunity for both parents and professionals to have interesting discussions regarding the general conditions of the establishment and the pedagogical approach applied in the crèche and the school. The management team was delighted to offer the parents the opportunity to participate in this event, where everyone could express their views, ask questions and find answers in a friendly and relaxed atmosphere.
Rats demonstrate helping behavior toward a soaked conspecific.
Sato, Nobuya; Tan, Ling; Tate, Kazushi; Okada, Maya
2015-09-01
Helping behavior is a prosocial behavior whereby an individual helps another irrespective of disadvantages to him or herself. In the present study, we examined whether rats would help distressed, conspecific rats that had been soaked with water. In Experiment 1, rats quickly learned to liberate a soaked cagemate from the water area by opening the door to allow the trapped rat into a safe area. Additional tests showed that the presentation of a distressed cagemate was necessary to induce rapid door-opening behavior. In addition, it was shown that rats dislike soaking and that rats that had previously experienced a soaking were quicker to learn how to help a cagemate than those that had never been soaked. In Experiment 2, the results indicated that rats did not open the door to a cagemate that was not distressed. In Experiment 3, we tested behavior when rats were forced to choose between opening the door to help a distressed cagemate and opening a different door to obtain a food reward. Irrespective of how they learned to open the door, in most test trials, rats chose to help the cagemate before obtaining a food reward, suggesting that the relative value of helping others is greater than the value of a food reward. These results suggest that rats can behave prosocially and that helper rats may be motivated by empathy-like feelings toward their distressed cagemate.

Electricity supply opportunities -- The Mexican door opens

Holland, H.W.
1993-01-01
Anyone who assumes that the Mexican market for electrical capacity is just a matter of selling equipment and services is in for a shock. The astute neighbor to the south is exploring privatization in the power sector with a style and flair that is uniquely Mexican. While free market-market forces have, to some extent, already transformed the manner in which new generating capacity is added in the US, a Mexico equivalent will not develop over night. Mexico is no place for the faint of heart. You have to play hard in order to win against competition almost equivalent to that of the US market and have the staying power to be around long enough to reap the rewards. This work presents the author's views concerning the manner in which competition has been introduced within the electricity supply market of the neighbor to the south

Process evaluation with qualitative approach through open interview, direct observation and documental analysis was performed in the city of Recife, northeastern Brazil. The main problems were: the deficient referral and counter-referral system; delayed return of laboratory test results; excessive number of families per team; difficulties in scheduling medical consultations; expenditures on medicines. Facilities were observed in the professional-user relationship, as well as in the geographical proximity of the health unit. ESF proved to be a narrow entrance door to Sistema Único de Saúde (SUS - Brazil's National Health System. Therefore, it deserves to be evaluated with a more critical look that takes into account, as a starting point, the needs of individuals who request its actions, as well as the reasoning which guides the actions of the subjects involved in care.
Radon concentrations in homes in an area of dolomite bedrock: Door County, Wisconsin

Hawk, K.; Stieglitz, R.D.; Norman, J.C.
1993-01-01
A statewide survey by the Wisconsin Department of Health and Social Services with U.S.E.P.A. assistance reported an anomalously high percentage of homes in Door County with radon concentrations in excess of 20 pCi/L. The results were of interest because the county is underlain by marine sedimentary rocks rather than the igneous and metamorphic crystalline types usually associated with elevated radon concentrations. A voluntary population of 55 homes was tested for radon using activated charcoal canisters. This population was also asked to provide questionnaire response data on family, home, and socioeconomic aspects. The data were separated into socioeconomic, energy efficiency, radon access, and karst level categories and statistically analyzed. A subpopulation was selected from the larger population for detailed site investigation, which included additional in-home air testing and, at some sites, water supply analysis and in-ground testing for radon. The field investigations collected information on the geology, soil, topography, and home construction and use. The results of the investigation verified and characterized the radon occurrences in Door County. The presence or absence of karst features is shown to be statistically significant to radon levels. 23 refs., 5 figs., 3 tabs

Phased array UT as an inspection technique in itself continues to gain wide acceptance. However, there is much room for improvement in terms of implementation of Phased Array (PA) technology for every unique NDT application across several industries (e.g. oil and petroleum, nuclear and power generation, steel manufacturing, etc.). Having full control of the phased array instrument and customizing a software solution is necessary for more seamless and efficient inspections, from setting the PA parameters, collecting data and reporting, to the final analysis. NDT researchers and academics also need a flexible and open platform to be able to control various aspects of the phased array process. A high performance instrument with advanced PA features, faster data rates, a smaller form factor, and capability to adapt to specific applications, will be discussed

The treatment chamber of patients has been simulating with MCNPX Code. Optimation of simulation design of Irradiation chamber is corresponding to ISO standards for 30 MeV cyclotron generator. The simulation has used the variation of door's materials that was applied at treatment room's door. The variation of materials was Stainless Steel 202 and Pb, the thickness Pb and stainless steel 202 with the thickness were 2 cm, respectively. Neutron flux that was radiated to stainless steel 202 in the sequence was 3.34195 × 105 n . Cm-2 s-1 and 8.41568 × 104 n . Cm-2 s-1, while for Pb was 4.01349 × 105 n . Cm-2 s-1 and 2.58058 × 104 n . Cm-2 s-1. The further, neutron flux that was radiated to Pb and stainless steel 202 with the thickness were 4 cm in sequence was 4.00601 × 105 n . Cm-2 s-1 and 1.71713 × 104 n . Cm-2 s-1 for Pb, while for SS 202 was 3.09925 × 105 n . Cm-2 s-1. From this ratio we concluded that material Pb absorbed higher neutron flux than material Stainless Steel 202. On the other hand, the cost of Pb was more expensive than Stainless Steel 202. In addition, the material Stainless Steel 202 was obtaine more easily than the material Pb. There fore to overcome the economics problem, can try to build the door with stainless still 202 sheet and Pb sheet together. The further, the neutron dose with 2 cm of thickness was 7.69603 × 10-2 Gy and 2.10623 × 10-2 Gy for SS 202, while for Pb was 4.19444 × 10-2 Gy and 1.50581 × 10-2 Gy. While the neutron dose with 4 cm of thickness for SS 202 was 9.39602 × 10-2 Gy and for Pb was 4.46541 × 10-2 Gy and 1.50502 × 10-2 Gy. We recommend that this simulation should be further optimized.

In this article, it designs an escape system for vehicles in water crashes. The structure mainly contains sensors, control organs and actuating mechanism for both doors and windows. Sensors judge whether the vehicle falls into water or is in the falling process. The actuating mechanism accepts the signal delivered by the control organs, then open the electronic central lock on doors and meanwhile lower the window. The water escape system is able to anticipate drowning situations for vehicles and controls both doors and windows in such an emergency. Under the premise of doors staying in an undamaged state, it is for sure that people in the vehicle can open the door while drowning in the water and safely escape.

Targeted antibiotic treatment reduces the infection risk of open fractures when soft tissue and bone are exposed to the environment. The risk of infection increases with higher degrees of injury. The Gustilo-Anderson system was developed to identify the degree of injury of open fractures and can be utilized to guide initial antibiotic therapy. Few studies have been published evaluating the potential impact of emergency medicine pharmacists in trauma, and currently no study has evaluated a pharmacist's influence on antibiotic selection and timing for open fractures. The objective of this study was to determine the impact of an emergency medicine pharmacist on initial antibiotic selection and timing in trauma patients with open fractures. This was a retrospective cohort study. Trauma alerts with open fractures from May 1, 2014 to June 30, 2016 were eligible for inclusion. The primary outcome was to determine if pharmacist participation during trauma resuscitation was associated with an increased proportion of initial antibiotic selection meeting guideline recommendations. The secondary outcome was the door-to-antibiotic administration time during resuscitation. Initial prophylactic antibiotic recommendations were met in 81% of trauma resuscitations when a pharmacist was present versus 47% without a pharmacist present (pfractures.

Full Text Available Le troisième roman d’Elizabeth Spencer, The Voice at the Back Door (1956, appartient à son cycle du Mississippi. Il traite des relations raciales et de la violence sudiste, deux thèmes qui n’avaient pas bonne presse à cette époque puisque le mouvement pour les droits civiques débutait. Le roman rappelle L’intrus (1948 de Faulkner en ce qu’il met en scène la recherche du coupable du meurtre d’un homme blanc. Cet article analyse la façon dont Spencer dépeint les manières du Sud en s’interrogeant sur les relations raciales. Le roman est également lu dans le contexte de sa publication puisque Spencer fut perçue comme une traîtresse par les Sudistes. Spencer utilise des sujets impopulaires pour révéler le paradoxe au cœur de la manière de vivre sudiste et montre combien le passé se rejoue constamment dans le présent.Elizabeth Spencer’s third novel, The Voice at the Back Door (1956, is part of her Mississippi cycle. It deals with race relations and southern violence, two highly controversial issues at the time since the Civil Rights Movements were beginning. The novel, reminiscent of William Faulkner’s Intruder in the Dust (1948, stages the search for a culprit after the murder of a white man. This paper focuses on Spencer’s portrait of southern manners and interracial relationships and analyzes the novel in the context of its publication. It will show that Spencer uses unpopular topics to expose the paradox at the core of the southern way of life and show that the past is constantly reenacted in the present.

Andreas Hazir is investigating the door seal contribution to the interior noise level of production vehicles. These investigations contain experimental contribution analyses of real production vehicles and of academic test cases as well as the development of a simulation methodology for noise transmission through sealing systems and side windows. The simulations are realized by coupling transient computational aeroacoustics of the exterior flow to nonlinear finite element simulations of the structural transmission. By introducing a linear transmission model, the setup and computational costs of the seal noise transmission are significantly reduced, resulting in the feasibility of numerical contribution analyses of real production vehicles.

Recently, a sheet metal forming simulation has become an indispensable tool for developing a new model of an automobile part within a limited short period. In these days, the utilization of a springback calculation of the formed part has been increasing. However, only a few papers on the prediction of surface defects have been reported in spite of serious needs.In this paper, surface defects in the door outer panel, especially those around the door handle embossment, have been investigated. Applying an explicit solver to the forming simulation, and an implicit solver to the springback calculation, we have tried to evaluate surface defects in the panel. In order to improve the accuracy of the simulation, numerical tools have been modeled including the precise shape of the draw beads so that the draw bead effects on both the material flow and the restraint on the springback deformation have been considered. Compared with the actual panel shape, which shows apparent surface defects, the simulated result has closely predicted the above defects around the embossment.To demonstrate the applicability of our simulation, a few sensitivity analyses have been carried out, modifying forming conditions such as blank holder force. Each result has shown slight but distinctive differences in the cross section profile of the panel. As a result, it has been realized that the influence of each considered factor on surface defects is qualitatively consistent with our practical knowledge

The aim of the study was to investigate, from the narratives of nine enrolled nurses and one nurses' aide directly involved in patient care, the deeper meaning of work satisfaction and dissatisfaction when working with the older people. Both nationally and internationally, there is little research documented regarding the working situation of the enrolled nurses and nurses' aides who make up the majority of care for older people today. With this in mind, it is important to focus on how these occupational groups experience their work with the older residents in municipal care, following a two-year intervention. The study is part of a larger longitudinal study, with a quasi-experimental design within the municipal system of care for older people in Sweden. The investigation was carried out following a two-year intervention, which included: education, support and clinical supervision. The interviews were performed 12 and 24 months after start of the intervention and were analysed with a phenomenological-hermeneutic method inspired by Ricoeur's philosophy. The findings from these narratives illustrated a change compared with the findings from the first interviews, when the nursing home had just opened. There was a shift from a dominance of dissatisfaction with work, to a dominance of work satisfaction and this was expressed in the following themes: experience of a changed perspective, experience of open doors, and experience of closed doors. Each theme emerged from several different subthemes and each subtheme that had been expressed in the caregivers' narratives was interpreted. The study shows that the caregivers' experience of work satisfaction in the workplace exceeded their experience of dissatisfaction and that the intervention, consisting of: education, support, and supervision might have facilitated this positive development where the older residents were prioritized. It also shows that communication and understanding between management and staff had increased

Highlights: • User satisfaction is compared in offices with high and low thermal control. • Thermal control is secondary in British and main system in Norwegian approach. • Individual thermal control in Norway improved satisfaction (35%) and comfort (20%). • The energy use is much higher in the Norwegian than British case studies. • A balance is required between energy efficiency and providing thermal comfort. - Abstract: Two office layouts with high and low levels of thermal control were compared, respectively traditional cellular and contemporary open plan offices. The traditional Norwegian practice provided every user with control over a window, blinds, door, and the ability to adjust heating and cooling. Occupants were expected to control their thermal environment to find their own comfort, while air conditioning was operating in the background to ensure the indoor air quality. In contrast, in the British open plan office, limited thermal control was provided through openable windows and blinds only for occupants seated around the perimeter of the building. Centrally operated displacement ventilation was the main thermal control system. Users’ perception of thermal environment was recorded through survey questionnaires, empirical building performance through environmental measurements and thermal control through semi-structured interviews. The Norwegian office had 35% higher user satisfaction and 20% higher user comfort compared to the British open plan office. However, the energy consumption in the British practice was within the benchmark and much lower than the Norwegian office. Overall, a balance between thermal comfort and energy efficiency is required, as either extreme poses difficulties for the other.
DOORS to the semantic web and grid with a PORTAL for biomedical computing.
Taswell, Carl
2008-03-01
The semantic web remains in the early stages of development. It has not yet achieved the goals envisioned by its founders as a pervasive web of distributed knowledge and intelligence. Success will be attained when a dynamic synergism can be created between people and a sufficient number of infrastructure systems and tools for the semantic web in analogy with those for the original web. The domain name system (DNS), web browsers, and the benefits of publishing web pages motivated many people to register domain names and publish web sites on the original web. An analogous resource label system, semantic search applications, and the benefits of collaborative semantic networks will motivate people to register resource labels and publish resource descriptions on the semantic web. The Domain Ontology Oriented Resource System (DOORS) and Problem Oriented Registry of Tags and Labels (PORTAL) are proposed as infrastructure systems for resource metadata within a paradigm that can serve as a bridge between the original web and the semantic web. The Internet Registry Information Service (IRIS) registers [corrected] domain names while DNS publishes domain addresses with mapping of names to addresses for the original web. Analogously, PORTAL registers resource labels and tags while DOORS publishes resource locations and descriptions with mapping of labels to locations for the semantic web. BioPORT is proposed as a prototype PORTAL registry specific for the problem domain of biomedical computing.
An automatic window opening system to prevent drowning in vehicles sinking in water

Objective: Every year about 400 people die in submersed vehicles in North America and this number increases to 2,000–5,000 in all industrialized nations. The best way to survive is to quickly exit through the windows. An Automatic Window Opening System (AWOS; patent protected) was designed to sense when a vehicle is in water and to open the electric windows, but only when the vehicle is upright. Methods: The AWOS consists of a Detection Module (DM), in the engine compartment, and a Power Window Control Module (PWCM) inside the driver’s door. The DM contains a Water Sensor, a Level Sensor and a Microcontroller Unit (MCU). The Level Sensor provides the angular orientation of the car using a 3-axis acceleration sensor and prevents automatic window opening if the car is outside the orientation range (±20° in the roll axis, ±30° in the pitch axis, with a 2 s delay). Systems were installed on two cars and one SUV. A crane lowered vehicles in water either straight down (static tests) or by swinging the vehicles to produce forward movement (dynamic tests). Results: In all tests, when the vehicles landed upright, windows opened immediately and effectively. When vehicles landed inverted, or at a very steep angle, the system did not engage until an upright and level position was attained. Conclusions: This system may help decrease drowning deaths in sinking vehicles. If occupants do not know, or forget, what to do, the open window could hopefully prompt them to exit safely through that window.

It is being realized that the traditional closed-door and market driven approaches for drug discovery may not be the best suited model for the diseases of the developing world such as tuberculosis and malaria, because most patients suffering from these diseases have poor paying capacity. To ensure that new drugs are created for patients suffering from these diseases, it is necessary to formulate an alternate paradigm of drug discovery process. The current model constrained by limitations for collaboration and for sharing of resources with confidentiality hampers the opportunities for bringing expertise from diverse fields. These limitations hinder the possibilities of lowering the cost of drug discovery. The Open Source Drug Discovery project initiated by Council of Scientific and Industrial Research, India has adopted an open source model to power wide participation across geographical borders. Open Source Drug Discovery emphasizes integrative science through collaboration, open-sharing, taking up multi-faceted approaches and accruing benefits from advances on different fronts of new drug discovery. Because the open source model is based on community participation, it has the potential to self-sustain continuous development by generating a storehouse of alternatives towards continued pursuit for new drug discovery. Since the inventions are community generated, the new chemical entities developed by Open Source Drug Discovery will be taken up for clinical trial in a non-exclusive manner by participation of multiple companies with majority funding from Open Source Drug Discovery. This will ensure availability of drugs through a lower cost community driven drug discovery process for diseases afflicting people with poor paying capacity. Hopefully what LINUX the World Wide Web have done for the information technology, Open Source Drug Discovery will do for drug discovery. Copyright © 2011 Elsevier Ltd. All rights reserved.

Particle transport problems are notorious for their difficulty. This fact requires that production level computer codes designed to address realistic engineering problems possess three important features: (i) high computational efficiency as measured by solution accuracy for a fixed computational cost; (ii) a wide variety of options to enhance robustness of the transport solver; and (iii) a broad collection of support codes that extend the reach of the transport solver to a wide variety of applications. The Discrete Ordinates of Oak Ridge System (DOORS) code package was designed with these features in mind. In this paper, capabilities of member codes in the DOORS package are overviewed with particular emphasis on two newly developed peripheral codes: BOT3P the mesh-generation and visualization code package, and GipGui the graphical user interface for the cross section manipulation code, GIP. Two large applications are used to illustrate the tight coupling between the peripheral codes and the DORT and TORT transport solvers in two and three dimensional geometries, respectively. These are: (i) criticality calculations for the C5G7MOX core benchmark; and (ii) dose distribution calculations for the Target Service Cell (TSC) of the Spallation Neutron Source (SNS). (Author)

Open Science Meets Stem Cells: A New Drug Discovery Approach for Neurodegenerative Disorders.

Neurodegenerative diseases are a challenge for drug discovery, as the biological mechanisms are complex and poorly understood, with a paucity of models that faithfully recapitulate these disorders. Recent advances in stem cell technology have provided a paradigm shift, providing researchers with tools to generate human induced pluripotent stem cells (iPSCs) from patient cells. With the potential to generate any human cell type, we can now generate human neurons and develop "first-of-their-kind" disease-relevant assays for small molecule screening. Now that the tools are in place, it is imperative that we accelerate discoveries from the bench to the clinic. Using traditional closed-door research systems raises barriers to discovery, by restricting access to cells, data and other research findings. Thus, a new strategy is required, and the Montreal Neurological Institute (MNI) and its partners are piloting an "Open Science" model. One signature initiative will be that the MNI biorepository will curate and disseminate patient samples in a more accessible manner through open transfer agreements. This feeds into the MNI open drug discovery platform, focused on developing industry-standard assays with iPSC-derived neurons. All cell lines, reagents and assay findings developed in this open fashion will be made available to academia and industry. By removing the obstacles many universities and companies face in distributing patient samples and assay results, our goal is to accelerate translational medical research and the development of new therapies for devastating neurodegenerative disorders.

Parkinsonism occurs in all ethnic groups worldwide; however, there are wide variations in the prevalence rates reported from different countries, even for neighboring regions. The huge socioeconomic burden of parkinsonism necessitates the need for prevalence studies in each country. So far, there is neither data registry nor prevalence information on parkinsonism in the Iranian population. The aim of our study was to estimate the prevalence rate of probable parkinsonism in a huge urban area in Iran, Tehran using a community-based door-to-door survey. We used a random multistage sampling of the households within the network of health centers consisting of 374 subunits in all 22 districts throughout the entire urban area of Tehran. Overall, 20,621 individuals answered the baseline checklist and screening questionnaire and data from 19,500 persons aged ≥30 years were entered in the final analysis. Health care professionals used a new six-item screening questionnaire for parkinsonism, which has been previously shown to have a high validity and diagnostic value in the same population. A total of 157 cases were screened for parkinsonism using the validated six-item questionnaire. After age and sex adjustment based on the Tehran population, the prevalence of parkinsonism was calculated as 222.9 per 100,000. Using the World Health Organization's World Standard Population, the standardized prevalence rate of parkinsonism was 285 per 100,000 (95% confidence interval 240-329). The male:female ratio of probable parkinsonism was calculated as 1.62, and there was a significant increase in the screening rate by advancing age. The calculated rates for the prevalence of parkinsonism in our study are closer to reports from some European and Middle Eastern countries, higher than reports from Eastern Asian and African populations, and lower than Australia. The prevalence rate of >200 in 100,000 for parkinsonism in Tehran, Iran could be considered a medium-to-high rate.

This study was designed to reevaluate the effectiveness of the Pavlov ratio in patients with cervical myelopathy. We studied 107 patients who underwent open door laminoplasty for the treatment of cervical myelopathy between the C3 to C7 levels. We determined the Pavlov ratio on preoperative and postoperative cervical spine lateral radiographs, the vertebral body-to-canal ratio on sagittal reconstruction CT scans, and the vertebral body-to-cerebrospinal fluid (CSF) column ratio on T2-weighted sagittal MR images from C3 to C6. The severity of myelopathy was determined using the JOA score on both preoperative and postoperative images. The recovery rate was also calculated. The Pavlov ratio in plain radiographs from patients with myelopathy was compared with the ratio of the vertebral body to the spinal canal on CT and MRI. The average Pavlov ratio between C3 and C6 ranged from 0.71 to 0.76. On CT scan, the average vertebral body-to-canal ratio between C3 and C6 ranged from 0.62 to 0.66. On MRI, the vertebral body-to-CSF column ratio between C3 and C6 ranged between 0.53 and 0.57. A positive correlation was noted between the Pavlov ratio and the vertebral body-to-canal ratio on sagittal-reconstruction CT (correlation coefficient = 0.497-0.627, p = 0.000) and between the Pavlov ratio and the vertebral body-to-CSF column ratio on MRI (correlation coefficient = 0.511-0.649, p = 0.000). We demonstrated a good correlation between the Pavlov ratio and both the vertebral body-to-canal ratio on CT and the vertebral body-to-CSF column ratio on MRI. Therefore, the Pavlov ratio can be relied upon to predict narrowing of the cervical spinal canal in the sagittal plane.

Cold fusion: Need to keep door wide open

Jones, S.E.
1992-01-01
Steven E. Jones of Brigham Young University in Provo, Utah, began work on cold fusion in 1986. Although insisting his work is markedly different from that of Stanley Pons and Martin Fleischmann at the nearby University of Utah, he nevertheless was tarred by the same brush that besmirched their sensational revelations in 1989. Whereas we were searching for tiny nuclear effects, they were looking for heat production, he explains. In no way, he insists, does his work substantiate the bold claims of heat generation by cold fusion in an electrochemical cell. In fact, Jones doublts Fleischmann and Pons' claims and sees evidence of either self-deception or hype in their actions. He adds, For useful energy production, thermonuclear (hot) fusion remains for more promising than that cold fusion claims of Pons and Fleischmann. But at the same time, Jones finds it necessary to appeal for tolerance for researchers brave enough to continue in the now unfashionable field of cold fusion

Via Google Earth, the National Snow and Ice Data Center (NSIDC) is demonstrating different methods of data presentation-visualization, animation and pinpointing of in situ data-to create new opportunities for those who currently provide and use cryospheric data and to empower Google Earth users with information to make their own decisions about hot topics such as climate change. Using visualization capabilities within Google Earth and the Keyhole Markup Language (KML), NSIDC has made images of glaciers, sea ice, snow and permafrost display over the globe. NSIDC is also creating animations within Google Earth for gridded, time-series data sets. These animations could, for example, demonstrate how sea ice extent has fluctuated over time. In situ data accessible through Google Earth enables users to locate and view cryospheric data using a common search criteria, spatial coverage. This fly-and-click functionality makes it easier for users to sort through ever-increasing amounts of data. The access to and visualization of data within Google Earth can expose new audiences to different applications of cryospheric data, enabling researchers in other scientific disciplines, commercial consultants and engineers, policy makers, educators and students to apply cryospheric information to their work. Google Earth also makes it possible to educate users in context and provide a multi-sensory learning experience. For example, users can view glaciers in the context of where they exist, see images of the formations, and access data and additional reference material.

Effects of the window openings on the micro-environmental condition in a school bus
Li, Fei; Lee, Eon S.; Zhou, Bin; Liu, Junjie; Zhu, Yifang
2017-10-01
School bus is an important micro-environment for children's health because the level of in-cabin air pollution can increase due to its own exhaust in addition to on-road traffic emissions. However, it has been challenging to understand the in-cabin air quality that is associated with complex airflow patterns inside and outside a school bus. This study conducted Computational Fluid Dynamics (CFD) modeling analyses to determine the effects of window openings on the self-pollution for a school bus. Infiltration through the window gaps is modeled by applying variable numbers of active computational cells as a function of the effective area ratio of the opening. The experimental data on ventilation rates from the literature was used to validate the model. Ultrafine particles (UFPs) and black carbon (BC) concentrations were monitored in ;real world; field campaigns using school buses. This modeling study examined the airflow pattern inside the school bus under four different types of side-window openings at 20, 40, and 60 mph (i.e., a total of 12 cases). We found that opening the driver's window could allow the infiltration of exhaust through window/door gaps in the back of school bus; whereas, opening windows in the middle of the school bus could mitigate this phenomenon. We also found that an increased driving speed (from 20 mph to 60 mph) could result in a higher ventilation rate (up to 3.4 times) and lower mean age of air (down to 0.29 time) inside the bus.

The radiation dose for the Dutch population due to discharges and emissions from processing industries has decreased substantially since 1994. However, the processing industry still makes the largest industrial contribution to the radiation dose. Nuclear installations and medical institutions contribute much less. There was a considerable decrease up to 2000, when two fertilizer enterprises stopped their activities in the Netherlands. Although the reported discharges of radioactive substances to water show a sharp decrease, the collective dose due to emissions to air has shown slight increases since 2001. The policy to reduce discharges in water has led to enterprises investing in wastewater treatment systems. Enterprises also take the radiological consequences into account when purchasing raw materials containing natural occurring radioactive material. The cost of the raw material obviously also influences the decision. Occupational exposure in processing plants was investigated using the data of the National Dose Registration and Information System (NDRIS). Often, employees' inhalation doses can amount to over 1 mSv per annum (i.e. 40% of the average annual radiation dose per capita of the Dutch population), but the dose limit of 6 mSv was not exceeded in any of the cases. We have developed and applied the chain model for regular emissions for assessing the radiation dose. Current dose assessments based on the chain model were found to fit with dose assessments based on measurements. The yearly variation in meteorological factors can affect the radiation dose for members of the public for 25% at locations close to the source when compared to calculations based on decade averaged meteorology.

Earlier tissue-type plasminogen activator (tPA) treatment for acute ischemic stroke increases efficacy, prompting national efforts to reduce door-to-needle times. We used lean process improvement methodology to develop a streamlined intravenous tPA protocol. In early 2011, a multidisciplinary team analyzed the steps required to treat patients with acute ischemic stroke with intravenous tPA using value stream analysis (VSA). We directly compared the tPA-treated patients in the "pre-VSA" epoch with the "post-VSA" epoch with regard to baseline characteristics, protocol metrics, and clinical outcomes. The VSA revealed several tPA protocol inefficiencies: routing of patients to room, then to CT, then back to the room; serial processing of workflow; and delays in waiting for laboratory results. On March 1, 2011, a new protocol incorporated changes to minimize delays: routing patients directly to head CT before the patient room, using parallel process workflow, and implementing point-of-care laboratories. In the pre and post-VSA epochs, 132 and 87 patients were treated with intravenous tPA, respectively. Compared with pre-VSA, door-to-needle times and percent of patients treated ≤60 minutes from hospital arrival were improved in the post-VSA epoch: 60 minutes versus 39 minutes (PLean process improvement methodology can expedite time-dependent stroke care without compromising safety.

Significant wind power ramp events (WPREs) are those that influence the integration of wind power, and they are a concern to the continued reliable operation of the power grid. As wind power penetration has increased in recent years, so has the importance of wind power ramps. In this paper, an optimized swinging door algorithm (SDA) is developed to improve ramp detection performance. Wind power time series data are segmented by the original SDA, and then all significant ramps are detected and merged through a dynamic programming algorithm. An application of the optimized SDA is provided to ascertain the optimal parameter of the original SDA. Measured wind power data from the Electric Reliability Council of Texas (ERCOT) are used to evaluate the proposed optimized SDA.

The deregulation of the gas market in the UK raises several difficulties. The door-to-door canvassing which has been used to incite customers to change their suppliers has led sometimes to complaint actions. Thus, price reductions were preferentially attributed to direct-debit customers and not to those that use gas meters with pre-payment tokens. In this context, the commercial reaction of British Gas company has been to propose new services concerning not only natural gas but also electric power and water distribution and sometimes also telephone.

Full Text Available Narrative research as a means for demand-driven policy and interventions This article reports on the advantages of performing narrative research discovering need patterns of families, children, local residents regarding quality of the pedagogical climate in their neighbourhood. A need pattern is a constructed set of related questions and needs that people express in response to life events, concrete experiences or within their current habitat. A method for narrative analysis was developed for two applications: use as a research tool and use as a change management tool. In this method professionals assume the role of narrative researchers and simultaneously learn to listen to the demands and needs of their potential clients from a more objective perspective. The method has been developed while performing transdisciplinary narrative research in the town-area of Hatert in Nijmegen, which will be presented as an example case throughout the text.

Posterior cervical decompression is an accepted treatment for multilevel cervical spondylotic myelopathy (CSM). Each posterior technique has its own advantages and disadvantages. In the present study, we compared the functional and radiological outcomes of expansive hemilaminectomy and laminoplasty with mini titanium plate in the treatment of multilevel CSM. Forty-four patients with multilevel CSM treated with posterior cervical surgery in Department of Orthopedic Surgery, Beijing Army General Hospital from March 2011 to June 2012 were enrolled in this retrospective study. Patients were divided into two groups by surgical procedure: Laminoplasty (Group L) and hemilaminectomy (Group H). Perioperative parameters including age, sex, duration of symptoms, operative duration, and intraoperative blood loss were recorded and compared. Spinal canal area, calculated using AutoCAD ® software(Autodesk Inc., San Rafael, CA, USA), and neurological improvement, evaluated with Japanese Orthopedic Association score, were also compared. Neurological improvement did not differ significantly between groups. Group H had a significantly shorter operative duration and significantly less blood loss. Mean expansion ratio was significantly greater in Group L (77.83 ± 6.41%) than in Group H (62.72 ± 3.86%) (P < 0.01). Both surgical approaches are safe and effective in treating multilevel CSM. Laminoplasty provides a greater degree of enlargement of the spinal canal, whereas expansive hemilaminectomy has the advantages of shorter operative duration and less intraoperative blood loss.

Non-invasive ventilation (NIV) is an evidence based management of acidotic, hypercapnic exacerbations of COPD. Previous national and international audits of clinical practice have shown variation against guideline standards with significant delays in initiating NIV. We aimed to map the clinical pathway to better understand delays and reduce the door-to-NIV time to less than 3 hours for all patients with acidotic, hypercapnic exacerbations of COPD requiring this intervention, by mandating the use of a guideline based educational management proforma.The proforma was introduced at 7 acute hospitals in North London and Essex and initiated at admission of the patient. It was used to record the clinical pathway and patient outcomes until the point of discharge or death. Data for 138 patients were collected. 48% of patients commenced NIV within 3 hours with no reduction in door-to-mask time during the study period. Delays in starting NIV were due to: time taken for review by the medical team (101 minutes) and time taken for NIV to be started once a decision had been made (49 minutes). There were significant differences in door-to-NIV decision and mask times between differing respiratory on-call systems, p < 0.05). The introduction of the proforma had no effect on door-to-mask times over the study period. Main reasons for delay were related to timely access to medical staff and to NIV equipment; however, a marked variation in practice within these hospitals was been noted, with a 9-5 respiratory on-call system associated with shorter NIV initiation times.

This study is to examine how viewing a Japanese garden affects Japanese patients with dementia. In a previous study, authors explored the effect on individuals with Alzheimer's disease of viewing an indoor Japanese garden at a nursing home in the United States and reported that viewing the garden significantly reduced the heart rate, evoked short-term and long-term memories, and improved behavioral symptoms. However, it was unclear whether these effects were caused by the design of Japanese garden or unfamiliarity of the design to Caucasians. We constructed a Japanese garden on the rooftop of a hospital in Japan and assessed with a total of 25 subjects on the following categories: (1) eye movement, (2) heart rate, and (3) behavior under four different conditions: (a) open view of the site before construction of the Japanese garden (the control space), (b) open view of the Japanese garden, (c) view of the Japanese garden through closed door, and (d) view of Japanese garden through closed door with the chrysanthemum scent. Findings/Results: Viewers' eyes scanned larger area while viewing the Japanese garden, and viewing the Japanese garden significantly reduced heart rate and improved behavioral symptoms than the control space. We also found that the effect of viewing the same Japanese garden differed across three conditions: the view through an open door, a closed door, and a closed door with added scent.

Full Text Available Background: Posterior cervical decompression is an accepted treatment for multilevel cervical spondylotic myelopathy (CSM. Each posterior technique has its own advantages and disadvantages. In the present study, we compared the functional and radiological outcomes of expansive hemilaminectomy and laminoplasty with mini titanium plate in the treatment of multilevel CSM. Methods: Forty-four patients with multilevel CSM treated with posterior cervical surgery in Department of Orthopedic Surgery, Beijing Army General Hospital from March 2011 to June 2012 were enrolled in this retrospective study. Patients were divided into two groups by surgical procedure: Laminoplasty (Group L and hemilaminectomy (Group H. Perioperative parameters including age, sex, duration of symptoms, operative duration, and intraoperative blood loss were recorded and compared. Spinal canal area, calculated using AutoCAD ® software(Autodesk Inc., San Rafael, CA, USA, and neurological improvement, evaluated with Japanese Orthopedic Association score, were also compared. Results: Neurological improvement did not differ significantly between groups. Group H had a significantly shorter operative duration and significantly less blood loss. Mean expansion ratio was significantly greater in Group L (77.83 ± 6.41% than in Group H (62.72 ± 3.86% (P < 0.01. Conclusions: Both surgical approaches are safe and effective in treating multilevel CSM. Laminoplasty provides a greater degree of enlargement of the spinal canal, whereas expansive hemilaminectomy has the advantages of shorter operative duration and less intraoperative blood loss.

This is the fourth article in the series on cold chain food preservation, which describes the use of refrigeration in the food industry. Milestones were the building of cold chains for food distribution and new processes such as margarine and lager beer, and the scaling up of existing processes (e.g. for dairy, meat and fish products). By quick freezing, introduced by Clarence Birdseye in 1925, refrigeration can also be used for long term preservation of food products, as a powerful alternative for canning food. [Dutch] Dit vierde artikel in de reeks 'voedingsmiddelenconservering door koudeketens' completeert de beknopte historie van de voedingsmiddelenindustrie met een overzicht van het in gebruik nemen van de koelmachine. Mijlpalen zijn het ontstaan van koudeketens voor voedseldistributie en de nu mogelijk geworden nieuwe processen, de bereiding van pilsbier en margarine, de opschaling van bereidingsprocessen en het lange-afstandtransport van bederfelijke producten zoals zuivelproducten, vlees en vis. Door diepvriezen als methode aan te wenden, uitgevonden door Clarence Birdseye in 1925, kan koude ook worden gebruikt om voedingsmiddelen lang houdbaar te maken, een superieur alternatief voor inblikken van voedsel.

The history of the Health and Community Center (CeSAC) No 24 began 21 years ago in the Ramón Carrillo district, in Villa Soldati neighborhood. This is a marginal urban area in the south of the CABA with a population with urgent needs. The work started with a group of professionals dealing with primary care practices, and it continues up to the present. The goal of our community mental health project is the creation of spaces for prevention and well-being including art in all its expressions, with the active participation of neighbors in the coordination of many activities. Through the symbolic opening of doors and making networks visible, we opened the CeSAC to universities, scientific societies, foundations, NGOs, neighbor committees, neighborhood boards, human rights organizations, formal and informal education centers, cultural centers, churches, community radios, in order to show the vital movements of the community, as we -as a team- are an integral part of it. Our spaces, workshops and programs are a collective socio-historical construction that achieves milestones such as thinking, thinking of us, getting together and achieving the participation from the community and the continuous training for everybody working and living in Soldati. The decentralization and democratization trend, and the heterarchical management of our organization favors the possibility of catalyzing the wishes, motivations and efforts of the healthcare team, neighbors and network nodes, thus benefiting the creative work that turns a dream into a hopeful reality.

There have been several exciting developments in the technologies commonly used n in the hardware hacking community. Advances in low cost additive-manufacturing processes (i.e. 3D-printers) and the development of openhardware projects, which have produced inexpensive and easily programmable micro-controllers and micro-computers (i.e. Arduino and Raspberry Pi) have opened a new door for individuals seeking to make their own devices. Here we describe the potential for these technologies to reduce costs in construction and development of submillimeter/millimeter astronomical instrumentation. Specifically we have begun a program to measure the optical properties of the custom plastics used in 3D-printers as well as the printer accuracy and resolution to assess the feasibility of directly printing sub- /millimeter transmissive optics. We will also discuss low cost designs for cryogenic temperature measurement and control utilizing Arduino and Raspberry Pi.

Subway suicide can significantly impact the general public. Platform Screen Doors (PSDs) are considered to be an effective strategy to prevent suicides at subway stations, but the evidence on their effectiveness is limited. We assessed the effectiveness of installing half- and full-height platform screen doors in reducing subway suicides using Poisson regression analysis. Ten-year monthly panel data for 121 subway stations between 2003 and 2012 in the Seoul metropolitan area were used for the analysis. We found that installing PSDs decreases fatal suicide cases by 89% (95% CI: 57-97%). We also found that the installation of full-height PSDs resulted in the elimination of subway suicides by completely blocking access to the track area; however, half-height PSDs, which do not extend to the ceiling of the platform, were not as effective as full-height ones. Our findings were based on the data from a single subway operator for a limited period of time. Accordingly, we did not consider the possibility that some passengers choose to die at a station run by other operators. Our study did not examine the potential substitution effects of other suicide methods. Installing physical barriers at subway stations can be an effective strategy to reduce the number of subway suicides; however, half-height PSDs are not as effective as full-height ones, even when they are as high as the height of an adult. Thus, these barriers should be made high enough so that nobody can climb over them. Copyright © 2016 Elsevier B.V. All rights reserved.

Open Access Data Centers as an Essential Partner to a Data Publication Journal
Carlson, D.; Pfeiffenberger, H.
2016-12-01
The success of Earth System Science Data derives in part from key infrastructure: digital object identifiers (doi) and open access data centers. Our concept that a data journal should promote access and exchange through publication of reviewed data descriptions presupposed third parties to hold the data. As minimum criteria for those data centers we expected international reputation for quality of service and an active lifetime extending at least a decade into the future. We also expected modern access interfaces offering geographic, topical and parameter-based browsing - so that users could discover related holdings through an ESSD link or discover ESSD by way of links in data sets revealed through the center's browse tools - and true open access. True open access means one or two clicks from abstract in ESSD to the data itself without barriers. We started with Pangaea and CDIAC. Data providers already used these centers, the staff welcomed the ESSD initiative and all parties cooperated on doi. With this initial support ESSD proved the basic concept of data publication and demonstrated utility to a larger group of data providers, many of whom suggested additional centers. So long as those data centers met expectations for open access and quality and durability of service, ESSD agreed to collaborate. Through back-door collaborations - e.g. service on particular data sets - ESSD developed working partnerships with more than 30 data centers in 13 countries. Data centers ask to join our list. We encourage those centers to stimulate local providers to submit a data set to ESSD, thus preserving our practical data-set by data-set partnership mode. For a few data centers where national policies impose a registration step, center staff and ESSD editors created bypass access routes to facilitate anonymous reviews. For ESSD purposes, open access and doi cooperation leading to reliable curation allows a win, win, win partnership among centers, providers, and journal.

The increasing availability and functionality of Open-Source software and hardware along with 3D printing, low-cost electronics, and proliferation of open-access resources for learning rapid prototyping are contributing to fundamental transformations and new technologies in environmental sensing. These tools invite reevaluation of time-tested methodologies and devices toward more efficient, reusable, and inexpensive alternatives. Building upon Open-Source design facilitates community engagement and invites a Do-It-Together (DIT) collaborative framework for research where solutions to complex problems may be crowd-sourced. However, barriers persist that prevent researchers from taking advantage of the capabilities afforded by open-source software, hardware, and rapid prototyping. Some of these include: requisite technical skillsets, knowledge of equipment capabilities, identifying inexpensive sources for materials, money, space, and time. A university MAKER space staffed by engineering students to assist researchers is one proposed solution to overcome many of these obstacles. This presentation investigates the unique capabilities the USDA-funded Openly Published Environmental Sensing (OPEnS) Lab affords researchers, within Oregon State and internationally, and the unique functions these types of initiatives support at the intersection of MAKER spaces, Open-Source academic research, and open-access dissemination.

Recent meta-analytic evidence suggests that clinical neuropsychological methods are not likely to uncover circumscribed cognitive impairments in the deficit syndrome of schizophrenia. To overcome this issue, we adapted a cognitive neuroscience perspective and used a new "chaining" habit learning task. Participants were requested to navigate a cartoon character through a sequence of 4 rooms by learning to choose the open door from 3 colored doors in each room. The aim of the game was to learn the full sequence of rooms until the character reached the outside. In the training phase, each stimulus leading to reward (open door in each room) was trained via feedback until the complete sequence was learned. In the probe phase, the context of rewarded stimuli was manipulated: in a given room, in addition to the correct door of that room, there also appeared a door which was open in another room. Whereas the training phase is dominantly related to basal ganglia circuits, the context-dependent probe phase requires intact medial-temporal lobe functioning. Results revealed that deficit and non-deficit patients were similarly impaired on the probe phase compared with controls. However, the training phase was only compromised in deficit patients. More severe negative symptoms were associated with more errors on the training phase. Executive functions were unrelated to performance on the "chaining" task. These results indicate that the deficit syndrome is associated with prominently impaired stimulus-response reinforcement learning, which may indicate abnormal functioning of basal ganglia circuits.

Shock absorber system for nuclear reactor ice condenser compartment

A shock absorber system was designed to absorb the energy imparted to doors in a nuclear reactor ice condenser compartment as they swing rapidly to an open position. Each shock absorber which is installed on a wall adjacent to each door is large and must absorb up to about 40,000 foot pounds of energy. The basic shock absorber component comprises foam enclosed in a synthetic fabric bag having a volume about twice the foam volume. A stainless steel knitted mesh bag of the same volume as the fabric bag, contains the fabric bag and its enclosed foam. To protect the foam and bags during construction activities at the reactor site and from the shearing action of the doors, a protective sheet metal cover is installed over the shock absorber ends and the surface to be contacted by the moving door. With the above shock absorber mounted on a wall behind each door, as the door is forcibly opened by steam pressure and air resulting from a pipe break in the reactor compartment, it swings at a high velocity into contact with the shock absorber, crushes the foam and forces it into the fabric bag excess material thus containing the foam fragmented particles, and minimizes build-up of pressure in the bag as a result of the applied compressive force

An x-ray inspection chamber has an access opening closable by doors, with a fail-safe optoelectronic system providing a light curtain across the access opening to sense the presence of an object such as an operator's arm in the opening. An adjustable table for supporting a component provides an infinitely variable film focal distance between the x-ray head and the component. A warning light is energised during a predetermined delay period before the head becomes operative after activation of a switch by the operator and the adjustment of the table and closure of the doors takes place during the delay period.

The need for accurate calculation of long-term care (LTC) pharmacies' costs to dispense (CTD) has become more important as payers have moved toward reimbursement models based on pharmacies' actual acquisition cost for drug products and the Centers for Medicare Medicaid Services (CMS) has implemented requirements that LTC pharmacies must dispense prescriptions for certain branded drugs in 14-day-or-less quantities. To (a) calculate the average cost that the typical independently owned, closed-door LTC pharmacy currently incurs to dispense and deliver a prescription to the resident of a client LTC facility and (b) estimate how CMS-mandated changes to a 14-day-or-less dispensing cycle would affect the typical LTC pharmacy's average CTD. The data requirements and measurement model were developed by academic researchers in consultation with an industry advisory committee of independent LTC pharmacy owners. A survey instrument was constructed to collect financial and operating data required to calculate the CTD. Surveys were distributed via 3 dissemination channels to approximately 1,000 independently owned, closed-door LTC pharmacies. The National Community Pharmacists Association mailed surveys to their LTC members; 3 major national wholesalers distributed surveys to their LTC customers through their newsletters; and 3 LTC group purchasing organizations distributed the surveys to their members through emails, newsletters, mailings, and/or regional meetings. Each pharmacy's CTD was calculated by dividing total LTC dispensing-related costs by the total number of prescriptions dispensed. Dispensing-related costs included costs incurred to physically dispense and deliver prescriptions (e.g., dispensing pharmacists' and technicians' salaries and costs of medication containers) and costs incurred to support the dispensing function (e.g., salaries of delivery and medical records personnel). A model based on dispensing-related fixed, variable, and semivariable costs was

The use of measures that are sensitive to subtle cognitive decline are recommended yet rarely used among clinical populations. The purpose of this study is to specify the types of memory changes observed among breast cancer survivors treated with chemotherapy and tamoxifen, by using an analytic test of memory, the Doors and People test, which uses age-adjusted norms. The participants were 40 women who were survivors of breast cancer, 20 of whom had completed chemotherapy treatment and 20 women who were treated only with tamoxifen. There were no significant differences between the two groups in overall scores and in all four subtests: visual memory, verbal memory, recall, and recognition measured by age-adjusted scores. Forty percent of patients in both of the groups were classified as having mild impairment in episodic memory. No between-group differences were found in the frequency of subjective, cognitive complaints. Subjective complaints were reported by 69% of patients but were unrelated to objective performance. Memory deficits were observed in breast cancer patients who receive either chemotherapy or tamoxifen alone compared to age-adjusted norms. The Doors and People Test is a sensitive measure of memory deficits that is feasible for use with clinical populations of breast cancer patients in order to monitor changes in cognitive function.

Full Text Available At the age of knowledge explosion and mass scientific information, I highlighted the importance of conducting open science in life and medical researches through the extensive usage of open software and documents. The proposal of conducting open science is to reduce the limited repeatability of researches in life science. I outlined the essential steps for conducting open life science and the necessary standards for creating, reusing and reproducing open materials. Different Creative Commons licenses were presented and compared of their usage scope and restriction. As a conclusion, I argued that open materials should be widely adopted in doing life and medical researches.

Control instrument for dose ratemeters
International Nuclear Information System (INIS)
Rutzki, B.
1974-01-01
The testing apparatus for the dose ratemeter has safety locking mechanisms for protection of the operating personnel allowing the apparatus to be opened only if the nuclear radiation source is shielded. For this purpose, the apparatus consists of a casing with an opening to be locked. The lock may be in the shape of a hollow cylinder matching with the likewise cylindrical wall of the casing through a ball bearing. The hollow-cylindrical part has an internal flange with a recess in which a shielding body in the shape of a roller is supported. The shielding body has a flattening on the jacket surface and penetrations for the nuclear radiation filled with absorbing material. Because of the eccentric bearing of the rotating shielding body with respect to the flange resp. the recess, the door connot be opened. Only after removal of the shielding block from the recess whereby the movement is caused from outside the casing by means of a knurling wheel, can the door be opened. Now, however, the shielding block is in the way of the beam from the nuclear radiation source and is shielding the door completely from it. (DG) [de

Full Text Available Weak openness and almost openness for arbitrary functions between topological spaces are defined as duals to the weak continuity of Levine and the almost continuity of Husain respectively. Independence of these two openness conditions is noted and comparison is made between these and the almost openness of Singal and Singal. Some results dual to those known for weak continuity and almost continuity are obtained. Nearly almost openness is defined and used to obtain an improved link from weak continuity to almost continuity.

Full Text Available A porta é um dos elementos mais antigos e fundamentais da estrutura espacial. Ela assume funções de barreira mecânica, térmica, visual e acústica. Assegura funções topológicas de junção ou disjunção entre os espaços para diferenciá-los ou fundi-los. Visando a compreendê-la em sua riqueza de significações, buscamos desvendar suas dimensões subjetivas, reconhecer o papel que tem nos relacionamentos sociais e expressar os estados psicológicos daí advindos. Este artigo evidencia também a possibilidade de se conhecer aspectos fundamentais da vida humana através da análise da inter-relação dos indivíduos com um elemento espacial. Do ponto de vista metodológico, este trabalho define-se, principalmente, como uma descrição apoiada numa reflexão fenomenológica.The door is one of the oldest and most fundamental elements of the space structure. It takes over functions of a mechanical, thermal, visual, and acoustic barrier. It also assures topological functions of junctions or disjunctions between spaces to differentiate or to unite them. In order to understand the door in all its richness of meanings we searched for uncovering its subjective dimensions, recognizing the valuable role that it plays in social relationships and tried to indicate the psychological states that can arise from them. This article also makes evident the possibility of getting to know fundamental aspects of human ways of life through the analysis of the inter-relationship between individuals and a spatial element. From a methodological point of view this paper can be defined as a descriptive study supported by a phenomenological reflection.

Fayle, G.W.; Cordingley, D.C.
1985-01-01
In order to demonstrate to the Atomic Energy Control Board that an air-lock inflatable seal will function after a LOCA exposure, an inflatable seal intended for personnel doors at the Pickering NGS 'B' was exposed to the thermal/moisture conditions of the LOCA requirement. While attending to determine the post-LOCA leakage rate it was found that additional leaks developed during each post-LOCA inflation/deflation cycle. The seal had been significantly and irreparably deteriorated by the LOCA exposure. The test has demonstrated that this type of LOCA exposed seal should not be expected to withstand either additional pressure above 207 kPa or additional inflation/deflation cycling. A higher inflation pressure and/or cycling will reduce the likelihood of a post-LOCA seal retaining an inflation pressure sufficient to prevent leakage across the seal

Door still open for action on issue of global warming

Crow, P.
1992-01-01
Global warming may or may not be a legitimate environmental threat, but Washington lobbyists consider it a legislative threat. It does not appear the current Congress will limit or tax use of U.S. fossil fuels, whose burning releases carbon dioxide into the atmosphere. This paper reports that some scientists have claimed a concentration of greenhouse gases in the atmosphere will result in a significant warming of the earth by 2050, threatening agriculture, altering ecosystems, and even melting polar ice and causing rising oceans to flood coastal areas and islands. In 1990 a United Nations panel of climate scientists predicted a 2 degrees C. increase in world temperatures within 35 years and 6 degrees by the end of the next century. Some scientists say preventing further increases will require a 60% reduction in current CO 2 emissions. The oil industry already is beginning to feel heat from the global warming issue. The Environmental Protection Agency calculates energy production and use is responsible for 57% of current emissions caused by man

A system for posting hazardous materials into and out of an enclosure, such as a glovebox, through a port in a wall of the enclosure. The port is normally closed by a door which cooperates with a removable end closure, on a container or the like when the latter is presented to and secured at the port. The container is secured in position at the port by means of a rotatable coupling ring. A single interlock ensures that the door cannot be opened in the absence of a container at the port and also that the container cannot be removed from the port when the door is open. In place of the container, a glove secured to a rigid sleeve may be used to enable the operator to perform a work function within the glovebox. (author)

A novel strategy applying an organophosphate-based insecticide paint on doors and windows in combination with long-lasting insecticide-treated nets (LLINs) was tested for the control of pyrethroid-resistant malaria vectors in a village setting in Vallée du Kou, a rice-growing area west of Burkina Faso. Insecticide Paint Inesfly 5A IGR™, comprised of two organophosphates and an insect growth regulator, was applied to doors and windows and tested in combination with pyrethroid-treated LLINs. The killing effect was monitored for 5 months by early morning collections of anophelines and other culicids. The residual efficacy was evaluated monthly by WHO bioassays using Anopheles gambiae 'Kisumu' and local populations of Anopheles coluzzii resistant to pyrethroids. The spatial mortality efficacy (SME) at distances of 1 m was also assessed against pyrethroid-susceptible and -resistant malaria vectors. The frequency of L1014F kdr and Ace-1 R G119S mutations was, respectively, reported throughout the study. The Insecticide Paint Inesfly 5A IGR had been tested in past studies yielding a long-term mortality rate of 80% over 12 months against An. coluzzii, the local pyrethroid-resistant malaria vector. The purpose of the present study is to test if treating smaller, targeted surfaces (e.g. doors and windows) was also efficient in killing malaria vectors. Treating windows and doors alone yielded a killing efficacy of 100% for 1 month against An. coluzzii resistant to pyrethroids, but efficacy reduced quickly afterwards. Likewise, WHO cone bioassays yielded mortalities of 80-100% for 2 months but declined to 90 and 40% 2 and 3 months after treatment, respectively. Mosquitoes exposed to insecticide paint-treated surfaces at distances of 1 m, yielded mortality rates of about 90-80% against local pyrethroids-resistant An. coluzzii during the first 2 months, but decreased to 30% afterwards. Anopheles coluzzii was reported to be exclusively the local malaria vector and

Open hardware for open science
CERN Bulletin
2011-01-01
Inspired by the open source software movement, the Open Hardware Repository was created to enable hardware developers to share the results of their R&D activities. The recently published CERN Open Hardware Licence offers the legal framework to support this knowledge and technology exchange. Two years ago, a group of electronics designers led by Javier Serrano, a CERN engineer, working in experimental physics laboratories created the Open Hardware Repository (OHR). This project was initiated in order to facilitate the exchange of hardware designs across the community in line with the ideals of “open science”. The main objectives include avoiding duplication of effort by sharing results across different teams that might be working on the same need. “For hardware developers, the advantages of open hardware are numerous. For example, it is a great learning tool for technologies some developers would not otherwise master, and it avoids unnecessary work if someone ha...

The components which are bound to impact are subjected to deformation even though it may be for a small scale. The efforts are always on for finding the best material to take impact that has no failure or moreover, less plastic deformation. A newly found material which is glass matrix steel named as ‘SAM2X5-630’ has astounding high elastic limit of 12.5GPa. Thus it can take powerful impact & regain its original shape avoiding the deformation of component under impact. The paper is focused on performing the Finite element analysis to assess the behaviour of ‘SAM2X5-630’ steel under impact loading of side door of car as well as impact of bullet on bulletproof jacket on which the material is assigned. The displacement or deformation occurred during impact is found to be lesser than known materials like Kevlar in bulletproof vest and Aluminium alloy in car door.

When a requirements engineering effort fails to meet expectations, often times the requirements management tool is blamed. Working with numerous project teams at Sandia National Laboratories over the last fifteen years has shown us that the tool is rarely the culprit; usually it is the lack of a viable information architecture with well- designed processes to support requirements engineering. This document illustrates design concepts with rationale, as well as a proven information architecture to structure and manage information in support of requirements engineering activities for any size or type of project. This generalized information architecture is specific to IBM's Rational DOORS (Dynamic Object Oriented Requirements System) software application, which is the requirements management tool in Sandia's CEE (Common Engineering Environment). This generalized information architecture can be used as presented or as a foundation for designing a tailored information architecture for project-specific needs. It may also be tailored for another software tool. Version 1.0 4 November 201

Certain safety-related multiple, interconnected electrical cabinets and the devices contained therein are required to perform their intended safety functions during and after a design basis seismic event. In general, seismic testing is performed to ensure the structural integrity of the cabinets and the functionality of their associated devices. Constrained by the shake table capacity, seismic testing is usually performed only for a limited number of interconnected cabinets. Also, original shake table tests performed usually did not provide detailed response information at various locations inside the cabinets. For operational and maintenance purposes, doors and panels of some cabinets may need to be opened while the adjacent cabinets are required to remain functional. In addition, in-cabinet response spectra need to be generated for the seismic qualification of new devices and the replacement parts. Consequently, seismic analysis of safety-related multiple, interconnected cabinets is frequently required for configurations which are different from the original tested conditions. This paper presents results of seismic tests of three interconnected safety-related cabinets and finite element analyses performed to compare the analytical results with those obtained from the cabinet seismic tests. Parametric analyses are performed to determine how many panels and doors can be opened while the adjacent cabinets still remain functional. The study indicates that for cabinets located in a high seismic zone, the critical damping of the cabinet is significantly higher than 5% to 7% typically used in qualifying electrical equipment. For devices mounted on the cabinet doors to performed their intended safety function, it requires stiffening of doors and that these doors be properly bolted to the cabinet frame. It also shows that even though doors and panels bolted to the cabinet frame are the primary seismic resistant element of the cabinet, opening of a limited number of them

Full Text Available This article explores the opening and the free usage of stored public sector data, supplied by state. In the age of Open Government and Open Data it’s not enough just to put data online. It should be rather weighed out whether, how and which supplied public sector data can be published. Open Data are defined as stored data which could be made accessible in a public interest without any restrictions for usage and distribution. These Open Data can possibly be statistics, geo data, maps, plans, environmental data and weather data in addition to materials of the parliaments, ministries and authorities. The preparation and the free access to existing data permit varied approaches to the reuse of data, discussed in the article. In addition, impulses can be given for Open Government – the opening of state and administration, to more transparency, participation and collaboration as well as to innovation and business development. The Open Data movement tries to get to the bottom of current publication processes in the public sector which could be formed even more friendly to citizens and enterprises.

A security system is implemented containing door locking system using passive type of RFID which can activate authenticate and validate the user and unlock the door in real time for secure access. The advantage of using passive RFID is that it functions without a battery and passive tags are lighter and are less expensive than the active tags. This system consists of fingerprint reader microcontroller RFID reader and PC. The RFID reader reads the id number from passive. The fingerprint sensor will check incoming image with enrolled data and it will send confirming signal for C program. If both RFID check and fingerprint image confirmation are matched the microcontroller will drive door motor according to sensors at door edges. This system is more secure than other systems because two codes protection method used.

Open Data, Open Source and Open Standards in chemistry: The Blue Obelisk five years on
2011-01-01
Background The Blue Obelisk movement was established in 2005 as a response to the lack of Open Data, Open Standards and Open Source (ODOSOS) in chemistry. It aims to make it easier to carry out chemistry research by promoting interoperability between chemistry software, encouraging cooperation between Open Source developers, and developing community resources and Open Standards. Results This contribution looks back on the work carried out by the Blue Obelisk in the past 5 years and surveys progress and remaining challenges in the areas of Open Data, Open Standards, and Open Source in chemistry. Conclusions We show that the Blue Obelisk has been very successful in bringing together researchers and developers with common interests in ODOSOS, leading to development of many useful resources freely available to the chemistry community.

Full Text Available The Psychiatric Reform has, as a fundamental principle, the treatment carried out outside the hospital, considering that the hospitalization should be an option only when the extra-hospital resources are not effective enough. However, multiple psychiatric readmissions are still frequent. The present study focuses on what happens outside of the hospital doors, analyzing elements of the community life of people who suffer from mental disorders,questioning if those experiences are related to the frequent necessity of hospitalization. Therefore, the perception of community support was investigated in patients with a high number of readmissions, in comparison with patients in their first hospitalization, in a general hospital in Porto Alegre (Brazil. The results showed that the community is a powerful source of help in crisis situations; nevertheless, the readmitted patients have weaker social bonds and a longer distance from the Atenção Básica (Primary Care, in comparison with the other group. For that reason, the family becomes the main source of support, what leads to an overburden for the relatives, and the hospital acquires a special status for these people, who see the hospital as the only alternative in a situation of crisis.

men and 27 women. The interviews were transcribed verbatim and analysed in Atlas.ti by two researchers, using attribute and structural coding.Our results show that foodbank clients use a combination of different strategies to cope with living on tight budgets. Most of them save money on food, non-food and social activities. Another strategy is to ask for support from family or friends for money, clothing or food. Some respondents are almost completely dependent on gifts from friends and the food parcel and some also reported being restricted in their social life and having lost friends. We found that lack of money is related to psychological suffering: sleeplessness, stress, fear, panic, depression and feelings of sadness. The causes mentioned for this suffering were: debts, persistent letters from creditors, and not being able to afford consumer goods and/or activities. Some respondents reported seeking to numb these feelings through the use of alcohol or cannabis. Others avoided opening letters or answering telephone calls.In the interviews, foodbank clients expressed their feelings about their situation. Shame was the most frequently mentioned emotion and related to the label of “foodbank client”, the working method of the foodbank or not being able to consume what they wanted to. Firstly, respondents felt ashamed about being a foodbank client, because this is not acceptable in their social and cultural environment, and there is a negative stigma associated with being a foodbank client rather than a “normal working citizen”. Some of the respondents try to hide the fact that they use a foodbank, while others stated that they liked to form friendships with other foodbank clients because they would be more likely to accept and understand them. Another reaction was to downplay the situation. Secondly, shame was connected to the way that the foodbank operates. Clients feel ashamed to have to show their administration in the assessment interview before they can

The hot cell of irradiated materials examination facility (IMEF), which has been operating since 1996, is generally contaminated by the radioactive nuclides of irradiated nuclear fuels and structural steels like Cs-137, Co-60, Co-134 and Ru-106. Especially Cs-137 is a main contaminated radioactive isotope which is easily moved here and there due to air flow in the hot cell, water-soluble, extremely toxic, and has a half-life of 30.23 years. To repair or fix the abnormal function of test apparatus installed in the hot cell, the maintenance door, so called a rear door and located at an intervention area, is opened to enter the hot cell inside. In a moment of opening the maintenance door, dirty air diffusion from the hot cell to an intervention area could be occurred in spite of increasing the rpm of exhaust fan to maintain much low under pressure, but an adjacent area to a maintenance door, i.e. intervention area, is very severely contaminated due to the unpredictable air flow. In this paper, the development of the radioactive substance contamination diffusion preventive equipment for a hot cell is studied to prevent dirty and toxic gaseous radioactive nuclides diffusion from a hot cell and installed at an intervention area of IMEF

Wheeled walkers (WWs) are used to improve mobility and for fall prevention in older persons, but not all users are satisfied with the usability of WWs. Intelligent WWs are being developed to improve the usability. The aim of this study was to support the development of intelligent WWs by investigating possible problems of using a WW. This study investigated 22 geriatric in-patients (median age 82 years) with and without their WW while opening a door against the direction of walking and passing through. Other possible problems when using WWs were identified by interview. Walking through the door was faster without than with using the WW (8.71 versus 12.86 s, p < 0.001), while interference between door and WW was documented in 41 of 44 (93 %) cases. Backward walking performance was better when using a WW with regard to gait speed, step width and walk ratio (all p < 0.002). Most referred problems when using a WW were walking downhill (83 %) and uphill (77 %) and obstacle crossing in general (77 %). Problems with opening a door against the direction of walking and the optimization of downhill and uphill walking as well as obstacle crossing should be regarded when developing an intelligent WW.

The United States' long-term demand for highly skilled nuclear industry workers is well-documented by the Nuclear Energy Institute. In addition, a study commissioned by the SRS Community Reuse Organization concludes that 10,000 new nuclear workers are needed in the two-state region of Georgia and South Carolina alone. Young adults interested in preparing for these nuclear careers must develop specialized skills and knowledge, including a clear understanding of the nuclear workforce culture. Successful students are able to enter well-paying career fields. However, the national focus on nuclear career opportunities and associated training and education programs has been minimal in recent decades. Developing the future nuclear workforce is a challenge, particularly in the midst of competition for similar workers from various industries. In response to regional nuclear workforce development needs, the SRS Community Reuse Organization established the Nuclear Workforce Initiative (NWI R ) to promote and expand nuclear workforce development capabilities by facilitating integrated partnerships. NWI R achievements include a unique program concept called NWI R Academies developed to link students with nuclear career options through firsthand experiences. The academies are developed and conducted at Aiken Technical College and Augusta Technical College with support from workforce development organizations and nuclear employers. Programs successfully engage citizens in nuclear workforce development and can be adapted to other communities focused on building the future nuclear workforce. (authors)

Cell Culture in Microgravity: Opening the Door to Space Cell Biology
Pellis, Neal R.; Dawson, David L. (Technical Monitor)
1999-01-01
Adaptational response of human cell populations to microgravity is investigated using simulation, short-term Shuttle experiments, and long-term microgravity. Simulation consists of a clinostatically-rotated cell culture system. The system is a horizontally-rotated cylinder completely filled with culture medium. Low speed rotation results in continuous-fall of the cells through the fluid medium. In this setting, cells: 1) aggregate, 2) propagate in three dimensions, 3) synthesize matrix, 4) differentiate, and 5) form sinusoids that facilitate mass transfer. Space cell culture is conducted in flight bioreactors and in static incubators. Cells grown in microgravity are: bovine cartilage, promyelocytic leukemia, kidney proximal tubule cells, adrenal medulla, breast and colon cancer, and endothelium. Cells were cultured in space to test specific hypotheses. Cartilage cells were used to determine structural differences in cartilage grown in space compared to ground-based bioreactors. Results from a 130-day experiment on Mir revealed that cartilage grown in space was substantially more compressible due to insufficient glycosaminoglycan in the matrix. Interestingly, earth-grown cartilage conformed better to the dimensions of the scaffolding material, while the Mir specimens were spherical. The other cell populations are currently being analyzed for cell surface properties, gene expression, and differentiation. Results suggest that some cells spontaneously differentiate in microgravity. Additionally, vast changes in gene expression may occur in response to microgravity. In conclusion, the transition to microgravity may constitute a physical perturbation in cells resulting in unique gene expressions, the consequences of which may be useful in tissue engineering, disease modeling, and space cell biology.

Opening the Door to Zero New HIV Infections in Closed Settings.

Prisons and other closed settings are high-risk environments for HIV and tuberculosis (TB) transmission. Prisoners often experience overcrowded living conditions and violence-including sexual assault-increasing their vulnerability to HIV and TB. However, high infection rates in prisons affect both prisoners and prison employees. Both groups, in interacting with their families and their communities, represent a potential risk of HIV transmission outside the prison setting. National HIV and TB strategies should therefore include measures to prevent transmission and increase access to HIV-related services in prisons. Courts have progressively recognized the human rights of prisoners, including the right to health and access to HIV-related services. A number of national and regional court decisions have affirmed that prison authorities have a duty of care to prisoners and an obligation to ensure that prisoners have access to HIV prevention measures and treatment. Policies and programs on HIV, AIDS, and TB for prison workplaces that are aligned with the ILO's international labor standards can benefit both prisoners and prison employees. In particular, the ILO's HIV and AIDS Recommendation, 2010 (No. 200) affirms the principle of universal access to HIV services and provides guidance for the HIV/TB response in prison settings.

Increasingly, open data, open-source projects are unearthing rich datasets and tools, previously impossible for more traditional avenues to generate. These projects are possible, in part, because of the emergence of online collaborative and code-sharing tools, decreasing costs of cloud-based services to fetch, store, and serve data, and increasing interest of individuals to contribute their time and skills to 'open projects.' While such projects have generated palpable enthusiasm from many sectors, many of these projects face uncharted paths for sustainability, visibility, and acceptance. Our project, OpenAQ, is an example of an open-source, open data community that is currently forging its own uncharted path. OpenAQ is an open air quality data platform that aggregates and universally formats government and research-grade air quality data from 50 countries across the world. To date, we make available more than 76 million air quality (PM2.5, PM10, SO2, NO2, O3, CO and black carbon) data points through an open Application Programming Interface (API) and a user-customizable download interface at https://openaq.org. The goal of the platform is to enable an ecosystem of users to advance air pollution efforts from science to policy to the private sector. The platform is also an open-source project (https://github.com/openaq) and has only been made possible through the coding and data contributions of individuals around the world. In our first two years of existence, we have seen requests for data to our API skyrocket to more than 6 million datapoints per month, and use-cases as varied as ingesting data aggregated from our system into real-time models of wildfires to building open-source statistical packages (e.g. ropenaq and py-openaq) on top of the platform to creating public-friendly apps and chatbots. We will share a whirl-wind trip through our evolution and the many lessons learned so far related to platform structure, community engagement, organizational model type
Testing for altruism and social pressure in charitable giving.
DellaVigna, Stefano; List, John A; Malmendier, Ulrike
2012-01-01
Every year, 90% of Americans give money to charities. Is such generosity necessarily welfare enhancing for the giver? We present a theoretical framework that distinguishes two types of motivation: individuals like to give, for example, due to altruism or warm glow, and individuals would rather not give but dislike saying no, for example, due to social pressure. We design a door-to-door fund-raiser in which some households are informed about the exact time of solicitation with a flyer on their doorknobs. Thus, they can seek or avoid the fund-raiser. We find that the flyer reduces the share of households opening the door by 9% to 25% and, if the flyer allows checking a Do Not Disturb box, reduces giving by 28% to 42%. The latter decrease is concentrated among donations smaller than $10. These findings suggest that social pressure is an important determinant of door-to-door giving. Combining data from this and a complementary field experiment, we structurally estimate the model. The estimated social pressure cost of saying no to a solicitor is $3.80 for an in-state charity and $1.40 for an out-of-state charity. Our welfare calculations suggest that our door-to-door fund-raising campaigns on average lower the utility of the potential donors.

Graphic nonfiction: what is it? Some call these books and articles science comics, but they're no joke: created through research and direct experience by artists invested in creating multiple entry points for new learners, comics can open doors for discovery as introduction, enrichment, or as a vital center point to teaching. Find out what educational pedagogists, scientists, and - yes! - students themselves think about reading, viewing, learning from, and creating science comics in the classroom. Karen Romano Young is the award-winning author of traditional and graphic fiction and nonfiction for children, including Doodlebug, the forthcoming Diving for Deep-Sea Dragons, and the Odyssey/Muse magazine comics feature Humanimal Doodles. In spring 2018 (Antarctic autumn) Young will work as part of a Bigelow Laboratory team studying the production of DMSP by phytoplankton, and the resulting cloud formation. This is invisible stuff, difficult for lay audiences to envision and comprehend. But the audience is already forming around "Antarctic Log," a science comic that tells the story of the science and the experience of doing climate research at Palmer Station as winter draws near. Science comics aren't just for enrichment. They're an invitation, providing multiple entry points for diverse learners. I have received unanticipated support from education groups (including NSTA and IRA), parenting groups, and special educators because these highly visual presentations of middle grade and middle school level material makes the stories and concepts accessible to atypical fiction- and science-reading audiences. As a result, I've learned a great deal about the underlying differences between my material and traditional, text-oriented materials in which visuals may be highly coordinated but are still ancillary. An article that might seem forbidding as text appears open to interpretation in my format, so that readers can pick where to begin reading and how to proceed through the

Surgical wound contamination leading to surgical site infection can result from disruption of the intended airflow in the operating room (OR). When personnel enter and exit the OR, or create unnecessary movement and traffic during the procedure, the intended airflow in the vicinity of the open wound becomes disrupted and does not adequately remove airborne contaminants from the sterile field. An increase in the bacterial counts of airborne microorganisms is noted during increased activity levels within the OR. Researchers have studied OR traffic and door openings as a determinant of air contamination. During a surgical procedure the door to the operating room may be open as long as 20 minutes out of each surgical hour during critical procedures involving implants. Interventions into limiting excessive movement and traffic in the OR may lead to reductions in surgical site infections in select populations.

Micro-electrical-mechanical system (MEMS) has become important for many industries such as automotive, home appliance, portable electronics, especially with the emergence of Internet of Things. Volume testing with temperature compensation has been essential in order to provide MEMS based sensors with repeatability, consistency, reliability, and durability, but low cost. Particularly, in the temperature calibration test, temperature uniformity of thermal cycling based calibration chamber becomes more important for obtaining precision sensors, as each sensor is different before the calibration. When sensor samples are loaded into the chamber, we usually open the door of the chamber, then place fixtures into chamber and mount the samples on the fixtures. These operations may affect temperature uniformity in the chamber. In order to study the influencing factors of sample-loading on the temperature uniformity in the chamber during calibration testing, numerical simulation work was conducted first. Temperature field and flow field were simulated in empty chamber, chamber with open door, chamber with samples, and chamber with fixtures, respectively. By simulation, it was found that opening chamber door, sample size and number of fixture layers all have effects on flow field and temperature field. By experimental validation, it was found that the measured temperature value was consistent with the simulated temperature value.

Already in the 1980s industrial tourism - people visiting operational companies - has been identified as a growing segment of regional tourism industries. Since then the pressure on companies to open their doors for other members of the society has only increased. Several scholars (e.g. Frew, 2000; Soyez, 1993; Mitchell & Orwig, 2002) have discussed the relevance of industrial tourism for regions and firms. There are several reasons to promote industrial tourism but also to keep doors closed....

Helium-air exchange flows through partitioned opening and two-opening
International Nuclear Information System (INIS)
Kang, T. I.
1997-01-01
This paper describes experimental investigations of helium-air exchange flows through partitioned opening and two-opening. Such exchange flows may occur following rupture accident of stand pipe in high temperature engineering test reactor. A test vessel with the two types of small opening on top of test cylinder is used for experiments. An estimation method of mass increment is developed to measure the exchange flow rate. Upward flow of the helium and downward flow of the air in partitioned opening system interact out of entrance and exit of the opening. Therefore, an experiment with two-opening system is made to investigate effect of the fluids interaction of partitioned opening system. As a result of comparison of the exchange flow rates between two types of the opening system, it is demonstrated that the exchange flow rate of the two-opening system is larger than that of the partitioned opening system because of absence of the effect of fluids interaction.

The impact of reducing door-to-balloon time on hospital revenues, costs, and net income is unknown. We prospectively determined the impact on hospital finances of (1) emergency department physician activation of the catheterization lab and (2) immediate transfer of the patient to an immediately available catheterization lab by an in-house transfer team consisting of an emergency department nurse, a critical care unit nurse, and a chest pain unit nurse. We collected financial data for 52 consecutive ST-elevation myocardial infarction patients undergoing emergency percutaneous intervention from October 1, 2004-August 31, 2005 and compared this group to 80 consecutive ST-elevation myocardial infarction patients from September 1, 2005-June 26, 2006 after protocol implementation. Per hospital admission, insurance payments (hospital revenue) decreased ($35,043 +/- $36,670 vs. $25,329 +/- $16,185, P = 0.039) along with total hospital costs ($28,082 +/- $31,453 vs. $18,195 +/- $9,242, P = 0.009). Hospital net income per admission was unchanged ($6962 vs. $7134, P = 0.95) as the drop in hospital revenue equaled the drop in costs. For every $1000 reduction in total hospital costs, insurance payments (hospital revenue) dropped $1077 for private payers and $1199 for Medicare/Medicaid. A decrease in hospital charges ($70,430 +/- $74,033 vs. $53,514 +/- $23,378, P = 0.059), diagnosis related group relative weight (3.7479 +/- 2.6731 vs. 2.9729 +/- 0.8545, P = 0.017) and outlier payments with hospital revenue>$100,000 (7.7% vs. 0%, P = 0.022) all contributed to decreasing ST-elevation myocardial infarction hospitalization revenue. One-year post-discharge financial follow-up revealed similar results: Insurance payments: $49,959 +/- $53,741 vs. $35,937 +/- $23,125, P = 0.044; Total hospital costs: $39,974 +/- $37,434 vs. $26,778 +/- $15,561, P = 0.007; Net Income: $9984 vs. $9159, P = 0.855.
