    Full Text Available Background. Ocular trauma is important cause of blindness. Birmingham Eye Trauma Terminology allows us to use a standardized eye injury terminology which permits an unambigous interpretation. The Eye Injury Registry enables the analysis of medical, epidemyologic and social data.The most frequent ocular injury ocular contusion has a relatively good prognosis. An adequate primary ocular repair and correct timing of pars plana vitrectomy are very important in open globe injury management. There still exist some controversial issues concerning the role of posterior segment surgery in open globe injuries. These include timing of surgery, prophylactic scleral buckle placement and a proper use of systemic and intravitreal antibiotics.Conclusions. With adequate primary ocular repair, the use of systemic, intravitreal antibiotics, scleral buckling and proper timing for pars plana vitrectomy the prognosis for ocular trauma cases can be better.

    Prediction of final visual outcome in ocular injuries is of paramount importance and various prognostic models have been proposed to predict final visual outcome. The objective of this study was to validate the predictive value of ocular trauma score (OTS) in patients with combat related open globe injuries and to evaluate the factors affecting the final visual outcome. Methods: Data of 93 patients admitted in AFIO Rawalpindi between Jan 2010 to June 2014 with combat related open globe ocular injuries was analysed. Initial and final best corrected visual acuity (BCVA) was categorized as No Light Perception (NLP), Light Perception (LP) to Hand Movement (HM), 1/200-19/200, 20/200-20/50, and =20/40. OTS was calculated for each eye by assigning numerical raw points to six variables and then scores were stratified into five OTS categories. Results: Mean age of study population was 28.77 ± 8.37 years. Presenting visual acuity was <20/200 (6/60) in 103 (96.23%) eyes. However, final BCVA of =20/40 (6/12) was achieved in 18 (16.82%) eyes, while 72 (67.28%) eyes had final BCVA of <20/200 (6/60). Final visual outcome in our study were similar to those in OTS study, except for NLP in category 1 (81% vs. 74%) and =20/40 in category 3 (30% vs. 41%). The OTS model predicted visual survival (LP or better) with a sensitivity of 94.80% and predicted no vision (NLP) with a specificity of 100%. Conclusion: OTS is a reliable tool for assessment of ocular injuries and predicting final visual outcome at the outset. (author)

    Occupational ocular trauma is an important cause of acquired monocular blindness in a rapidly industrialising country like India. Knowledge of the epidemiology of occupational eye injuries is essential to formulate viable industrial safety measures. We retrospectively reviewed all patients with occupational open globe injuries between 1994 and 1998. We documented the circumstances of the injuries, their clinical findings and the use of appropriate protective eyewear at the time of the injury. The visual acuity 6 months after the injury was the final outcome measure. In this study period we examined 43 patients with open globe injuries sustained at the work place. Thirty-four (79.1%) patients were young males. The iron and steel industry accounted for 19 (44.2%) cases while 8 (18.6%) patients each were from the agricultural, mining and other small scale industrial sectors. At the time of the injury, 33 (76.7%) were not wearing the recommended protective eyewear and 6 (13.9%) were under the influence of alcohol. The injuries were mild in 6 (13.9%), moderate in 18 (41.9%) and severe in 19 (44.2%) patients. At the end of 6 months, 2 (4.7%) patients had a visual acuity of 6/12 or better, 4 (9.3%) had a visual acuity of 6/18 to 6/60 and 29 (67.4.%) had a vision of eyewear and alcohol-free environment at the work place is likely to reduce the incidence of severe occupational open globe injuries.

    Full Text Available AIM : To evaluate the prognostic value of OTS in open globe injuries. MATERIAL METHOD : Retrospective analysis of 77 eyes with open globe injuries was done from 01/07/2013 to 31/12/2014. Patients were assigned raw score sum based on initial V/A, and ocular findings then classified into 5 categories for predicting final visual outcome based on ocular Trauma score (OTS. RESULT : We estimated final V/A in 77 cases of open globe injuries (64.93% had raw sc ore between 65.91 (category 3, 4 Six months after the injury, 42.85% patients of categories 1 (raw score 0 - 44 achieved V/A of PL/HM as compared to 17% in OTS study. 16 patients with raw compared to OTS study. We reported comparable visual outcome with OT S study except in category 1 & 2. CONCLUSION: OTS score is valuable in triage, patient counseling and decision making for the management of ocular trauma. We recommend that OTS should be used routinely for open globe injuries as it is a simple guide

    Full Text Available Aim: To evaluate closed glob injuries related to occupational accidents of patients who had official occupational accident records. Material and Method: The medical records of patients with ocular injuries who referred to Department of Ophthalmology or emergency of Uludag University, School of Medicine between January 2010 and December 2013 with official occupational accident report were retrospectively reviewed. The patients with closed globe injuries following trauma were included. Age, sex, the injured eye, the cause of the trauma, whether the precautions were taken or not by the patient, the damage due to trauma were recorded. Results: According to the official records, 108 patients referred to our clinic with closed globe injury related to occupational accident. One hundred twenty eyes of 108 patients ( 2 females, 106 males were evaluated. The mean age of the patients was 33±8.6 years. The most frequent cause of injury was foreign bodies on the ocular surface followed by blunt trauma. The mean age of the patients injured with foreign bodies was found to be significantly lower than the patients injured with blunt objects (p=0.039. Thirteen patients reported that they had used preventive equipment. Discussion: It is of utmost importance that the awareness of the workers should be raised and they should be educated about the use of preventive equipment to prevent the occupational eye injuries. The education of particularly the younger patients about the occupational injuries when they begin to work may decrease the rate of occupational accident related eye injuries.

    Full Text Available AIM: To analyze clinical characteristics and postoperative outcomes after open globe injury. METHODS: Demographic characteristics(age, gender, eye trauma, profession, cause of injury and injured part, as well as complications and prognosis were analyzed in 152 cases(152 eyesof open globe injury. RESULTS: Patients with open globe injury had an average age of 40.45±38.32 years old with a 5.9:1 male-to-female gender ratio. The left-to-right eye ratio was 1.27:1. Most patients were workers, farmers, or retired. The most common etiologies were scratches, boxing, and falls. Zone Ⅲ was the most commonly injured part. Iridoptosis or iris incarceration, retinal detachment, vitreal prolapse, hyphema or hypopyon, and vitreous hemorrhage were the most common complications. Visual acuity improved in 86 cases postoperatively but ophthalmectomy was still required in 25 eyes. CONCLUSION: Vision can be improved after surgery in open globe injury. However, patients are usually seriously injured and improvement is minimal, thereby resulting in a great loss to patients and society.

    Full Text Available Open globe injury (OGI is a severe form of eye trauma estimated at 2-3.8/100,000 in the United States. Most pediatric cases occur at home and are the result of sharp object penetration. The aim of this article is to review the epidemiology, diagnosis, management, and prognosis of this condition by conducting a systematic literature search with inclusion of all case series on pediatric OGI published between 1996 and 2015. Diagnosis of OGI is based on patient history and clinical examination supplemented with imaging, especially computed tomography when indicated. Few prospective studies exist for the management of OGI in pediatric patients, but adult recommendations are often followed with success. The main goals of surgical management are to repair the open globe and remove intraocular foreign bodies. Systemic antibiotics are recommended as medical prophylaxis against globe infection, or endophthalmitis. Other complications are similar to those seen in adults, with the added focus of amblyopia therapy in children. Severe vision decline is most likely due to traumatic cataracts. The ocular trauma score, a system devised to predict final visual acuity (VA in adults, has proven to be of prognostic value in pediatric OGI as well. Factors indicating poor visual prognosis are young age, poor initial VA, posterior eye involvement, long wound length, globe rupture, lens involvement, vitreous hemorrhage, retinal detachment, and endophthalmitis. A thorough understanding of OGI and the key differences in epidemiology, diagnosis, management, and prognosis between adults and children is critical to timely prevention of posttraumatic vision loss early in life.

    To determine the risk factors leading to positive intraocular culture in patients with open globe injury. A prospective interventional study involving 110 eyes of 110 patients of more than 15 years of age, presenting with open globe injury, was undertaken. Emergency repair of the injured globe was done. Prolapsed intraocular tissue or aqueous humour was sent for microbial work up before repair. In endophthalmitis cases intravitreal antibiotics were given according to the antimicrobial sensitivity. Chi-square and logistic regression analysis were used to determine the risk factors. Fifty-six patients showed microbial contamination. Bacteria were cultured in 42 patients and fungi in 14 patients. Nineteen patients developed endophthalmitis, of which 18 patients showed microbial growth initially. In univariate analysis, initial visual acuity (8 mm, P 72 h, P 8 mm, P = 0.013) were associated with increased risk of positive microbial culture. Six patients had intraocular foreign body but were culture negative. Age, gender, site of injury and presence of cataract did not significantly affect the culture positivity. Microbial contamination is a risk factor for the development for endophthalmitis. Despite the high frequency of microbial contamination, it develops only in few cases. Systemic antibiotics, virulence of the organism and host factors play a role in the manifestation of endophthalmitis. Prophylaxis with intraocular antibiotics should be strongly considered in cases with poor vision at presentation, larger corneoscleral laceration, delayed surgical intervention and uveal tissue or vitreous prolapse.

    Full Text Available AIM: To investigate the epidemiologic characteristics and outcomes of open globe injury in Shanghai. METHODS: A retrospective study was conducted for 148 unilateral open globe injury cases presenting to a tertiary referral hospital of Shanghai. Electronic medical records were reviewed and phone surveys were conducted to collect and analyze 1 background of patient; 2 setting of injury and clinical signs at presentation; 3 treatment procedure and outcome; 4 quality of life after injury. RESULTS: There were more male patients (77.03% than females (22.97%, more temporary habitants (79.05% than residents (20.95%. The subjects in this study presented a significantly lower constitutional status of education than that of the whole Shanghai population (P<0.001. Occupational injury was the first cause of injuries (39.86%, followed by home accident (20.27%, road accident (16.89%, violent behavior (16.89% and outdoor injury (6.08%. The 143 subjects (96.62% were not wearing spectacles at the time of injury. Of all patients, 77 subjects (52.03% had the outcome of no vision (including enucleation. The classification and regression tree (CART prognosis presents 59.58% sensitivity to predict visual survival correctly and 80.19% specificity to predict no vision correctly. The patients whose injured eye had no vision reported more reduction of life quality. CONCLUSION: We found that male subject, temporary habitants, low educational status and no eyewear are risk factors of open globe injury in Shanghai. Occupational injury is the leading cause. CART analysis presents a certain agreement to the actual visual outcome. The injury imposes negative impact on quality of life especially in no vision cases. The education of eye protection may help to avoid the injury.

    Full Text Available Craniofacial trauma is often associated with orbital and ocular injuries. We report a case of a 21-year-old male with motor vehicular accident, orbital roof blow-in fracture, cerebrospinal fluid (CSF leak, and left sided globe luxation with corneal abrasion and complete conjunctival denuding. The patient was managed by a multispeciality team and the eyeball was protected by amniotic membrane graft (AMG biological dressing with novel use of inverted sterile metallic bowl as mechanical protection till the patient stabilized. During surgery, eyeball was reposited and ocular surface was reconstructed using amniotic membrane and symblepharon ring. Surgical correction and plating of the facial fractures and dural repair with autologus tensor fascia lata was done. Post surgery ocular surface was intact, ocular motility was well preserved and the globe was prephthisical. Traumatic eyeball luxation is a rare, but dramatic presentation which may occur in a blow in fracture when the intra orbital volume reduces and expels the eye ball out of the socket. This may be associated with extra ocular muscle rupture or optic nerve avulsion. The visual prognosis is nil in majority cases. However, the management is targeted towards globe preservation in view of psychological benefit and ease of cosmetic or prosthetic rehabilitation. Knowing the mechanism of luxation helps to plan the management. A stepwise approach for globe salvage is recommended. Team efforts to take care of various morbidities with special steps to safeguard the eye help to optimize outcomes.

Classification of open globe injury was based on the Birmingham Eye Trauma Terminology (BETT. Records were obtained with hospital permission via the in-house electronic patient management system, and the case notes of all patients with a diagnosis of open globe injury were scrutinised. Patients with prior ocular trauma, pre-existing ocular conditions affecting the visual acuity, contrast sensitivity, central vision or corneal thickness, as well as those with a history of previous intraocular or refractive surgery were excluded. Analysis of data was with SPSS version 20.0. Ordinal logistic regression analysis was used to examine the association between prognostic factors and visual outcome.RESULTS: This study involved 220 patients (n=222 eyes. The most common place of injury was the home (51.8%, followed by the workplace (23.4%. Among children aged less than 16y of age, domestic-related injury was the predominant cause (54.6%, while in those aged 16y and above, occupational injuries were the most common cause (40.0%. Most eyes (76.5% had an initial visual acuity worse than 3/60, and in half of these, the visual acuity improved. The visual outcome was found to be significantly associated with the initial visual acuity (P<0.005, posterior extent of wound (P<0.001, length of wound (P<0.001, presence of hyphaema (P<0.001 and presence of vitreous prolapse ((P<0.005.CONCLUSION:The most common causes of open globe injury are domestic accidents and occupational injuries.

    2017-01-01

    Full Text Available Objectives: To evaluate demographic characteristics and clinical outcomes of work-related open globe injuries in the most industrialized region of Turkey. Materials and Methods: The demographic and medical records of patients with work-related open globe injuries who presented to the ophthalmology or emergency departments with an official occupational accident report were retrospectively reviewed. Visual acuity categories were defined according to the World Health Organization. The injury types and zones of the open globes were classified according to Birmingham Eye Trauma Terminology System. Results: Among 479 patients with work-related eye injuries in 5 years, there were 102 eyes of 101 patients with open globe injuries (21%. The mean age of the patients was 34.5±8.9 years with a mean follow-up of 12.5±12.6 months. The injuries peaked in June in the hour between 12:00 and 13:00. Eighty-six percent presented to emergency services within 12 hours after the injury. Twenty-two percent of the patients had been wearing protective eyewear at the time of injury. The open globe injuries were penetrating in 51%, intraocular foreign body in 40%, rupture in 7% and perforation in 2% of the eyes. The most frequent finding was traumatic cataract. Final visual acuity of 33.3% of patients was below 3/60. Seventy-eight percent of patients that had visual acuity worse than 6/18 at presentation had visual acuity of 6/18 or better at final visit. Sixty-three percent of eyes which had injuries involving all 3 zones resulted in phthisis bulbi, enucleation or evisceration. Conclusion: Work-related open globe injuries may have severe consequences such as visual impairment and blindness among the young male working population in industrialized areas. Nearly half of the occupational open globe injuries resulted in visual impairment and blindness.

    Purpose: To evaluate the significance of multislice CT for the diagnosis of uncertain penetrating globe injuries. Materials and Methods: Based on a retrospective chart review between 2002 and 2007, we identified 59 patients presenting with severe ocular trauma with uncertain rupture of the globe due to massive subconjunctival and/or anterior chamber hemorrhage. The IOP (intraocular pressure) was within normal range in all patients. High resolution multidetector CT (MD-CT) scans (16 slice scans) with axial and coronar reconstructions were performed in all patients. The affected eye was examined for signs of penetrating injury such as abnormal eye shape, scleral irregularities, lens dislocation or intravitreal hemorrhages. Four experienced radiologists read the CT scans independently. Beside the diagnosis, the relevant morphological criteria and the optimal plane orientation (axial or coronar) were specified. The sensitivity, specificity, and negative and positive predictive value were calculated. Additionally the interobserver variability was determined by applying the Cohen's kappa test. Surgical sclera inspections were performed in all cases as a standard of reference. The evaluations of the CT examination were compared with the surgery reports. Results: 59 patients were evaluated (42 men, 17 women). The mean age was 29 years (range 7-91). In 17 patients a rupture of the globe was diagnosed during surgery. 12 of these 17 penetrating injuries (70.6%) were classified correctly by MDCT, 5 of the 17 (29.4%) were not detectable. 42 patients did not have an open globe injury. 41 of these patients were diagnosed correctly negative by MDCT, and one patient was classified false positive. This results in a sensitivity of 70% with a specificity of 98%. There was high inter-rater agreement with kappa values between 0.89-0.96. Most discrepancies were caused by wrong negative findings. The most frequent morphologic criteria for open globe injury were the deformation (n

    Full Text Available Research from evolutionary psychology suggests that the mere presence of eye images can promote prosocial behavior. However, the “eye images effect” is a source of considerable debate, and findings across studies have yielded somewhat inconsistent support. We suggest that one critical factor may be whether the eyes really need to be watching to effectively enhance prosocial behavior. In three experiments, we investigated the impact of eye images on prosocial behavior, assessed in a laboratory setting. Participants were randomly assigned to view an image of watching eyes (eyes with direct gaze, an image of nonwatching eyes (i.e., eyes closed for Study 1 and averted eyes for Studies 2 and 3, or an image of flowers (control condition. Upon exposure to the stimuli, participants decided whether or not to help another participant by completing a dull cognitive task. Three independent studies produced somewhat mixed results. However, combined analysis of all three studies, with a total of 612 participants, showed that the watching component of the eyes is important for decision-making in this context. Images of watching eyes led to significantly greater inclination to offer help as compared to images of nonwatching eyes (i.e., eyes closed and averted eyes or images of flowers. These findings suggest that eyes gazing at an individual, rather than any proxy to social presence (e.g., just the eyes, serve as a reminder of reputation. Taken together, we conclude that it is “eyes that pay attention” that can lift the veil of anonymity and potentially facilitate prosocial behavior.

    Eye globe abnormalities can be readily detected on dedicated and non-dedicated CT and MR studies. A primary understanding of the globe anatomy is key to characterising both traumatic and non-traumatic globe abnormalities. The globe consists of three primary layers: the sclera (outer), uvea (middle), and retina (inner layer). The various pathological processes involving these layers are highlighted using case examples with fundoscopic correlation where appropriate. In the emergent setting, trauma can result in hemorrhage, retinal/choroidal detachment and globe rupture. Neoplasms and inflammatory/infective processes predominantly occur in the vascular middle layer. The radiologist has an important role in primary diagnosis contributing to appropriate ophthalmology referral, thereby preventing devastating consequences such as vision loss

Clinical findings at presentation were recorded, and details of initial repair and follow-up surgeries were analyzed. Differences in visual acuity and surgical outcomes were compared based on subspecialty training of the initial surgeon.Results: The charts of 282 adult patients were analyzed, and 193 eyes had at least 6 months of follow-up for analysis. Eighty-six eyes (44.6% required follow-up surgery within the first year, and 39 eyes (20.2% were enucleated. Eyes initially treated by a vitreoretinal (VR surgeon were 2.3 times (P=0.003 more likely to improve by one Ocular Trauma Score (OTS visual acuity category and 1.9 times (P=0.027 more likely to have at least one more follow-up surgery at 6 months compared to eyes treated by non-VR surgeons. Patients with more anterior injuries treated by a VR surgeon were more likely to improve by one OTS visual acuity category compared to those treated by non-VR surgeons (P=0.004 and 0.016 for Zones I and II, respectively. There was no difference in visual acuity outcomes for eyes with posterior injuries (P=0.515 for Zone III.Conclusion: Eyes initially treated by a VR surgeon are more likely to improve by one OTS visual acuity category than those initially treated by a non-VR surgeon.

    Full Text Available Purpose. To evaluate the tilt, decentration, and internal higher-order aberrations (HOAs of sutured posterior-chamber intraocular lenses (IOLs in patients with open globe injuries. Methods. 46 consecutive patients (47 eyes who underwent transsclerally sutured IOL implantation were enrolled in this prospective cohort study. Nineteen eyes had a history of open globe injury. The tilt and decentration of the IOLs and the visual quality were measured 1 month after surgery. Results. The horizontal tilt and decentration of the IOLs in the open-globe-injury group were significantly higher than those in the control group (both P<0.05. In the open-globe-injury group, the horizontal decentration was significantly greater in the limbus-sclera-involved group (n=11 than in the only-cornea-involved group (n=8, P=0.040. The internal coma, 3rd-order, and total HOA values at pupil sizes of 4 mm (P=0.006 and 6 mm (P=0.013 were significantly higher in the open-globe-injury group than in the controls. Consequently, the optical quality data for the modulation transfer function and the Strehl ratio (all P<0.05 were significantly poorer in the open-globe-injury group. Conclusions. Open globe injuries damage the structural integrity of the eyeball, resulting in more-misaligned sutured IOLs and poorer visual quality.

    2017-07-01

    Full Text Available Introduction: Cases of penetrating ocular trauma due to osseous material are limited, so reported incidents are valuable in determining outcomes and proper treatment courses.Case description: We report a case of an open globe injury of the left eye with an intraocular foreign body occurring after a firework exploded in the hand of a 22-year-old man. The patient presented with light perception vision in the injured eye with a full-thickness limbal laceration and dense hyphema obscuring fundoscopy. CT scan revealed a hyperdense foreign body juxtaposed to the lens. Immediate surgical intervention to repair the globe rupture revealed a defect in the anterior capsule and small, white objects in the posterior chamber that were promptly removed. Pathologic investigation determined these fragments to be cortical bone likely from the patient’s phalanges. Results and discussion: There was no evidence of endophthalmitis or keratitis from time of injury to the five-month follow-up, suggesting that the risk of infection may be low and therefore it may be reasonable to manage these injuries with a period of observation.

    This paper introduces the OpenWebGlobe project (www.openwebglobe.org) and the OpenWebGlobe SDK (Software Development Kit) - an open source virtual globe environment using WebGL. Unlike other (web-based) 3d geovisualisation technologies and toolkits, the OpenWebGlobe SDK not only supports the content authoring and web visualization aspects, but also the data processing functionality for generating multi-terabyte terrain, image, map and 3d point cloud data sets in high-performance and cloud-based parallel computing environments. The OpenWebGlobe architecture is described and the paper outlines the processing and the viewer functionality provided by the OpenWebGlobe SDK. It then discusses the generation and updating of a global 3d base map using OpenStreetMap data and finally presents two show cases employing the technology a) for implementing an interactive national 3d geoportal incorporating high resolution national geodata sets and b) for implementing a 3d geoinformation service supporting the real-time incorporation of 3d point cloud data.

    Full Text Available History of present illness: A 46-year-old male presented to the emergency department (ED with severe left eye pain and decreased vision after tripping and striking the left side of his head on the corner of his wooden nightstand. The patient arrived as an inter-facility transfer for a suspected globe rupture with a protective eye covering in place; thus, further physical examination of the eye was not performed by the emergency physician in order to avoid further leakage of aqueous humor. Significant findings: The patient’s computed tomography (CT head demonstrated a deformed left globe, concerning for ruptured globe. The patient had hyperdense material in the posterior segment (see green arrow, consistent with vitreous hemorrhage. CT findings that are consistent with globe rupture may include a collapsed globe, intraocular air, or foreign bodies. Discussion: A globe rupture is a full-thickness defect in the cornea, sclera, or both.1 It is an ophthalmologic emergency. Globe ruptures are almost always secondary to direct perforation via a penetrating mechanism; however, it can occur due to blunt injury if the force generated creates sufficient intraocular pressure to tear the sclera.2 Globes most commonly rupture at the insertions of the intraocular muscles or at the limbus. They are associated with a high rate of concomitant orbital floor fractures.2,3 Possible physical examination findings include a shallow anterior chamber on slit-lamp exam, hyphema, and an irregular “teardrop” pupil. Additionally, a positive Seidel sign, which is performed by instilling fluorescein in the eye and then examining for a dark stream of aqueous humor, is indicative of a globe rupture.4 CT is often used to assess for globe rupture; finds of a foreign body, intraocular air, abnormal contour or volume of the globe, or disruption of the sclera suggest globe rupture.2 The sensitivity of CT scan for diagnosis of globe rupture is only 75%; thus, high clinical

    Purpose To demonstrate a Scheimpflug-based imaging procedure for investigating the depth- and time-dependent strain response of the human cornea to inflation testing of whole eye globes. Methods Six specimens, three of which with intact corneal epithelium, were mounted in a customized apparatus within a humidity and temperature-monitored wet chamber. Each specimen was subjected to two mechanical tests in order to measure corneal strain resulting from application of cyclic (cyclic regimen) and constant (creep regimen) stress by changing the intra-ocular pressure (IOP) within physiological ranges (18–42 mmHg). Corneal shape changes were analyzed as a function of IOP and both corneal stress-strain curves and creep curves were generated. Results The procedure was highly accurate and repeatable. Upon cyclic stress application, a biomechanical corneal elasticity gradient was found in the front-back direction. The average Young's modulus of the anterior cornea ranged between 2.28±0.87 MPa and 3.30±0.90 MPa in specimens with and without intact epithelium (P = 0.05) respectively. The Young's modulus of the posterior cornea was on average 0.21±0.09 MPa and 0.17±0.06 MPa (P>0.05) respectively. The time-dependent strain response of the cornea to creep testing was quantified by fitting data to a modified Zener model for extracting both the relaxation time and compliance function. Conclusion Cyclic and creep mechanical tests are valuable for investigating the strain response of the intact human cornea within physiological IOP ranges, providing meaningful results that can be translated to clinic. The presence of epithelium influences the results of anterior corneal shape changes when monitoring deformation via Scheimpflug imaging in inflation experiments of whole eye globes. PMID:25397674

    Most post-traumatic acute infectious endophthalmitis occur within a week of open globe trauma, necessitating early antibiotic prophylaxis. There are few randomised studies that demonstrate the benefits of prophylactic antibiotics. This randomised controlled non-inferiority trial was aimed at determining the incidence of post-traumatic endophthalmitis using established intravenous/oral prophylaxis and comparing this to the incidence using oral antibiotics only. All adult patients admitted with open globe injury were included. Those with proven endophthalmitis, high-risk features, who underwent primary evisceration and those allergic to the trial antibiotics were excluded. Patients were randomised to receive either intravenous cefazolin and oral ciprofloxacin or oral ciprofloxacin and oral cefuroxime for 3 days from admission. Acute endophthalmitis was the primary outcome. Patients completed the study if they were followed up for 6 weeks post injury. Three hundred patients were enrolled, with 150 in each arm. There were 99 exclusions. Seven patients developed endophthalmitis despite prophylaxis-2.0% (three cases) in the intravenous and oral arm, compared with 2.7% (four cases) in the oral-only arm-this difference was not statistically significant ( p=0.703). The incidence of endophthalmitis with prophylaxis was 2-3%. Selected patients with open globe injuries (without high-risk features) may receive either intravenous cefazolin and oral ciprofloxacin, or oral cefuroxime and oral ciprofloxacin as prophylaxis against acute endophthalmitis-the latter regimen has the advantage of shortening patients' hospital stays and reducing costs. Non-inferiority study-design limitations should be taken into account, however. Published by the BMJ Publishing Group Limited.

    To compare the clinical presentation and final visual outcome of open globe injuries in children and adults in a referral hospital over a 30-month period. This is an institutional-based prospective study of open globe injuries cases presenting in the emergency department between July 2003 and December 2005. Patients were divided in 2 groups: group 1, children (2-15 years), and group 2, adults (>15 years). All the patients were admitted and emergency surgical interventions were undertaken. The clinical features at presentation and the final visual acuity are compared. Chi-square and Fisher exact tests were used for statistical analysis. Ninety and 84 patients were included in group 1 and group 2, respectively. The most common places of injuries were home or while playing outdoor games in group 1 (67%) and workplace in group 2 (53.5%). The presenting features were significantly more grave in group 2. These included poor presenting visual acuity (p=0.012), vitreous prolapse (p=0.002), presence of relative afferent pupillary defect (p=0.001), and incidence of endophthalmitis (p=0.004). Time interval between injury and surgical intervention (p=0.018) was better in group 2. Other features, such as presence of hyphema, uveal tissue prolapse, cataract, intraocular foreign body, and length or location of laceration were similar in both groups. The final visual outcome was similar in the groups (p = 0.21), with approximately half of the patients achieving vision of 20/60 or better in each group. The majority of injuries in children and adults occurred in their homes or workplaces, respectively. Although the clinical presentations of open globe injuries were significantly more grave in adults than in children, the final visual outcomes were similar.

    To describe the technique and the results of the preparation of pre-cut corneas for Descemet's stripping automated endothelial keratoplasty (DSAEK) during a 3-year period at the Central Eye Bank of Iran (CEBI). The method of preparation of pre-cut corneas from donated whole globes at the CEBI is described and the frequency and percentage of pre-cut corneas prepared for DSAEK, between April 2009 and March 2012, are specified. Moreover, post-operative reports are reviewed for any complaints about using pre-cut tissues for DSAEK. Out of the 1,518 donated whole globes appropriate for DSAEK, 1,478 (97.4 %) pre-cut corneas were successfully prepared. The method of preparation failed in 40 (2.6 %) cases. Based on the eye bank post-operative reports, thickness of pre-cut tissues for DSAEK was deemed unacceptable in only 6 (0.4 %) cases prior to surgery; five of these were too thick and one was too thin. Preparation of pre-cut corneas, for DSAEK from donated whole globes, in the CEBI is a safe and easy method, with very good preservation of endothelial cells after the preparation of the pre-cut corneas and reduced risks from corneal manipulation.

    PURPOSE  To describe histologic anterior segment changes in eyes affected with primary lens displacement (PLD) and secondary glaucoma. METHODS  Histologic sections stained with H&E from canine eyes enucleated because of PLD and secondary glaucoma were examined. RESULTS  Thirteen eyes from 12 patients were evaluated. Four dogs were castrated males and eight spayed females. Median age was 8 years of age (range 3-13). Breeds included seven terriers and five other breeds. All eyes examined demonstrated varying degrees of inflammation involving the iris and cleft. Mononuclear and melanophagic infiltration of the cleft was found in all specimens. Four globes also showed polymorphonuclear infiltrate. Pre-iridal fibrovascular membranes were clearly identified in 10 of 13 eyes. Total inflammatory score was significantly greater in all globes examined compared with an age-matched group of normal dogs. The posterior pigmented iris epithelium demonstrated a consistent pattern of hyperplasia and/or hypertrophy and cystic degeneration, more prominent in the more central regions. In some cases, hyperplasia was of greatest severity in the mid-iris and associated with thinning or flattening of the pupillary region. CONCLUSIONS  These results suggest that lens instability may be associated with chronic inflammation and secondary glaucoma. Mechanical irritation from an unstable lens may result in hypertrophy and/or hyperplasia of the posterior pigmented iris epithelium and subsequent cellular exfoliation and release of melanin. An inflammatory reaction directly or indirectly related to melanin release may obstruct the outflow pathways ultimately leading to glaucoma and loss of vision. Use of topical steroids may be warranted in dogs with PLD. © 2012 American College of Veterinary Ophthalmologists.

    Purpose Identify a reproducible measure of axial globe position (AGP) for multicenter studies of patients with thyroid eye disease (TED). Methods This is a prospective, international, multicenter, observational study in which 3 types of AGP evaluation were examined: radiologic, clinical, and photographic. In this study, computed tomography (CT) was the modality to which all other methods were compared. CT AGP was measured from an orthogonal line between the anterior lateral orbital rims to the cornea. All CT measurements were made at a single institution by 3 individual clinicians. Clinical evaluation was performed with exophthalmometry. Three clinicians from each clinical site assessed AGP with 3 different exophthalmometers and horizontal palpebral width using a ruler. Each physician made 3 separate measurements with each type of exophthalmometer, not in succession. All photographic measurements were made at a single institution. AGP was measured from lateral photographs in which a standard marker was placed at the anterior lateral orbital rim. Horizontal and vertical palpebral fissure were measured from frontal photographs. Three trained readers measured 3 separate times, not in succession. Exophthalmometry and photography method validity was assessed by agreement with CT (mean differences calculation, ICC’s, Bland-Altman figures). Correlation between palpebral fissure and CT AGP was assessed with Pearson correlation. Intraclinician and interclinician reliability was evaluated using intraclass correlation coefficients (ICC). Results Sixty-eight patients from 7 centers participated. CT mean AGP was 21.37mm (15.96 – 28.90mm) right, 21.22mm (15.87 – 28.70mm) left (ICC 0.996 and 0.995). Exophthalmometry AGP fell between 18mm and 25mm. Intraclinician agreement across exophthalmometers was ideal (ICC 0.948 – 0.983). Agreement between clinicians was greater than 0.85 for all upright exophthalmometry measurements. Photographic mean AGP was 20.47mm (10.92 – 30

The spacecraft viewed three regions of the sky: part of the Large Magellanic Cloud (LMC), the Hickson Cluster Group 16 (HCG-16), and the star HR 1099. These targets were chosen because they all present a variety of X-ray extended and point sources and are very interesting regions. The expanding cauldon in the Large Magellanic Cloud The Large Magellanic Cloud also known as the Nebula Major is about 20 thousand light years in diameter. Situated 160 thousand light years from Earth, it is one of two irregularly shaped galaxies that are easily seen with the naked eye in the southern hemisphere. These galaxies are satellites of the Milky Way and appear to be slowly spiralling into our own Galaxy. The first image obtained by the EPIC-PN X-ray cameras viewed the 30 Doradus region of the Large Magellanic Cloud. Also called the Tarantula Nebula, 30 Doradus is a cauldron of creation where exploding stars are releasing vast amounts of matter and where new stars are being born. The image presents the million degree temperatures of the emitting medium, with blue indicating the hottest regions; green intermediate temperatures and red the coldest regions.

Once you've experienced the visually rich and highly compelling nature of data delivered via virtual globes with their highly engaging context of 3D, it's hard to go back to a flat 2D world. Just as the sawbones of not-too-long-ago have given way to sophisticated surgical operating theater, today's medium for information exchange is just beginning to leap from the staid chalkboards and remote libraries to fingertip navigable 3D worlds. How we harness this technology to serve a world inundated with information will describe the quality of our future. Our instincts for discovery and entertainment urge us on. There's so much we could know if the world's knowledge was presented to us in its natural context. Virtual globes are almost magical in their ability to reveal natural wonders. Anyone flying along a chain of volcanoes, a mid-ocean ridge or deep ocean trench, while simultaneously seeing the different depths to the history of earthquakes in those areas, will be delighted to sense Earth's dynamic nature in a way that would otherwise take several paragraphs of "boring" text. The sophisticated concepts related to global climate change would be far more comprehensible when experienced via a virtual globe. There is a large universe of public and private geospatial data sets that virtual globes can bring to light. The benefit derived from access to this data within virtual globes represents a significant return on investment for government, industry, the general public, and especially in the realm of education. Data access remains a key issue. Just as the highway infrastructure allows unimpeded access from point A to point B, an open standards-based infrastructure for data access allows virtual globes to exchange data in the most efficient manner possible. This data can be either free or proprietary. The Open Geospatial Consortium is providing the leadership necessary for this open standards-based data access

    "The Global Learning and Observations to Benefit the Environment (GLOBE) Program is an international science and education program that provides students and the public worldwide with the opportunity to participate in data collection and the scientific process, and contribute meaningfully to our understanding of the Earth system and global environment" (www.globe.gov ). GLOBE Program has a rich community of students, teachers, scientists, trainers, country coordinators, and alumni across the world, technologically spanning both high- and low-end users. There are 117 GLOBE participating countries from around the world. GLOBE's Science data protocols and educational material span atmosphere, biosphere, hydrosphere, soil (pedosphere), and Earth as a System scientific areas (http://www.globe.gov/do-globe/globe-teachers-guide). GLOBE's Data and Information System (DIS), when first introduced in 1995, was a cutting edge system that was well-received and innovative for its time. However, internet-based technologies have changed dramatically since then. Projects to modernize and evolve the GLOBE DIS started in 2010, resulting in today's GLOBE DIS. The current GLOBE DIS is now built upon the latest information technologies and is engaging and supporting the user community with advanced tools and services to further the goals of the GLOBE Program. GLOBE DIS consists of over 20 years of observation and training data, a rich set of software systems and applications for data entry, visualization, and analysis, as well as tools for training users in various science data protocols and enabling collaborations among members of the international user community. We present the existing GLOBE DIS, application technologies, and lessons learned for their operations, development, sustaining engineering, and data management practices. Examples of GLOBE DIS technologies include Liferay System for integrated user and content management, a Postgress/PostGIS database, Ruby on Rails for Data

    Since 19 May, the ground floor of the Globe has been housing a contemporary art exhibition. Meyrin's Contemporary Art Fund Committee has given six artists free rein to think up projects for the area surrounding the Globe, which is still a blank canvas. The exhibition entitled 'Urban Utopias', which explores the question 'How to experience the town?', consists of preparatory sketches and models of the works proposed by the artists. The projects on display include a metal ring symbolising the LHC accelerator, a statue consisting of pieces of broken wooden furniture, metal and bamboo, three metres in height, and even a projection of a computer-generated design for a ziggurat adjoining the Globe. Urban Utopias 19 May to 18 June, open Wednesday to Sunday from 2 p.m. to 6 p.m., Thursday until 9 p.m. Entrance free.

  12. Evolving Capabilities for Virtual Globes

    Though thin-client spatial visualization software like Google Earth and NASA World Wind enjoy widespread popularity, a common criticism is their general lack of analytical functionality. This concern, however, is rapidly being addressed; standard and advanced geographic information system (GIS) capabilities are being developed for virtual globes--though not centralized into a single implementation or software package. The innovation is mostly originating from the user community. Three such capabilities relevant to the earth science, education, and emergency management communities are modeling dynamic spatial phenomena, real-time data collection and visualization, and multi-input collaborative databases. Modeling dynamic spatial phenomena has been facilitated through joining virtual globe geometry definitions--like KML--to relational databases. Real-time data collection uses short scripts to transform user-contributed data into a format usable by virtual globe software. Similarly, collaborative data collection for virtual globes has become possible by dynamically referencing online, multi-person spreadsheets. Examples of these functions include mapping flows within a karst watershed, real-time disaster assessment and visualization, and a collaborative geyser eruption spatial decision support system. Virtual globe applications will continue to evolve further analytical capabilities, more temporal data handling, and from nano to intergalactic scales. This progression opens education and research avenues in all scientific disciplines.

    to determine the frequency and severity of dry eye syndrome (DES) in primary open-angle glaucoma (POAG) patients that are newly diagnosed or already receiving beta blocker instillation therapy. A total of 127 patients (190 eyes) with POAG were divided into two groups. Group 1 included 55 newly diagnosed patients (88 eyes), group 2-72 POAG patients (102 eyes) instilling timolol 0.5% twice daily into the affected eye. The control group included 20 patients (40 eyes) aged 60-88 years (73.6 ± 9.2 years on average) with early age-related cataract. DES was found in 69 POAG patients (79%) who was just starting their topical hypotensive therapy and 85 of those (84%) under treatment (p = 0.39). One should take into account when prescribing ocular hypotensive therapy that newly diagnosed POAG patients usually already suffer from a dry eye. The use of topical beta blockers that contain preservatives exacerbates dry eye signs and symptoms in these patients.

    Limited normative data are available for the unipedal stance test (UPST), making it difficult for clinicians to use it confidently to detect subtle balance impairments. The purpose of this study was to generate normative values for repeated trials of the UPST with eyes opened and eyes closed across age groups and gender. This prospective, mixed-model design was set in a tertiary care medical center. Healthy subjects (n= 549), 18 years or older, performed the UPST with eyes open and closed. Mean and best of 3 UPST times for males and females of 6 age groups (18-39, 40-49, 50-59, 60-69, 70-79, and 80+) were documented and inter-rater reliability was tested. There was a significant age dependent decrease in UPST time during both conditions. Inter-rater reliability for the best of 3 trials was determined to be excellent with an intra-class correlation coefficient of 0.994 (95% confidence interval 0.989-0.996) for eyes open and 0.998 (95% confidence interval 0.996-0.999) for eyes closed. This study adds to the understanding of typical performance on the UPST. Performance is age-specific and not related to gender. Clinicians now have more extensive normative values to which individuals can be compared.

    Patients with LS have an inborn growth hormone resistance, resulting in failure to generate IGF-1. The purpose of this study was to evaluate the size of the eye and orbit in LS. We retrospectively reviewed the MR imaging of the brain in 9 patients with LS for the following parameters: axial diameter of the globe, interzygomatic distance, perpendicular distance from the interzygomatic line to margins of the globe, medial-to-lateral diameter of the orbit at the anterior orbital rim, distance from the anterior orbital rim to the anterior globe, maximal distance between the medial walls of the orbits, lateral orbital wall angle, lateral orbital wall length, and mediolateral thickness of the intraorbital fat in the most cranial image of the orbit. All measurements were made bilaterally. Twenty patients referred for MR imaging for unrelated reasons served as control subjects. Compared with the control group, the patients with LS had a significantly smaller maximal globe diameter and shallower but wider orbits due to a shorter lateral wall, a smaller medial distance between the orbits, and a larger angle of the orbit. The ratio between the most anterior orbital diameter and the globe was greater than that in controls. The position of the globe was more anterior in relation to the interzygomatic line. Shallow and wide orbits and small globes relative to orbital size are seen in LS and may be secondary to IGF-1 deficiency.

Anterior laminar insertion depth (ALID was defined as the vertical distance between the anterior laminar insertion and a reference plane connecting the Bruch's membrane openings (BMO. The mean LC depth (mLCD was approximated by dividing the area enclosed by the anterior LC, the BMO reference plane, and the two vertical lines for ALID measurement by the length between those two vertical lines. The LC curvature index was defined as the difference between the mLCD and the ALID. The factors influencing the LC curvature index were evaluated.The ALID and mLCD were significantly larger in POAG eyes than in healthy controls (P -6 dB and moderate-to-advanced glaucoma (MD < -6 dB, P = 0.95.LC posterior bowing was increased in POAG eyes, and was significantly associated with structural optic nerve head (ONH changes but not with functional glaucoma severity. Quantitative evaluation of LC curvature can facilitate assessment of glaucomatous ONH change.

    The eyes-open (EO) and eyes-closed (EC) states have differential effects on BOLD-fMRI signal dynamics, affecting both the BOLD oscillation frequency of a single voxel and the regional homogeneity (ReHo) of several neighboring voxels. To explore how the two resting-states modulate the local synchrony through different frequency bands, we decomposed the time series of each voxel into several components that fell into distinct frequency bands. The ReHo in each of the bands was calculated and compared between the EO and EC conditions. The cross-voxel correlations between the mean frequency and the overall ReHo of each voxel's original BOLD series in different brain areas were also calculated and compared between the two states. Compared with the EC state, ReHo decreased with EO in a wide frequency band of 0.01-0.25 Hz in the bilateral thalamus, sensorimotor network, and superior temporal gyrus, while ReHo increased significantly in the band of 0-0.01 Hz in the primary visual cortex, and in a higher frequency band of 0.02-0.1 Hz in the higher order visual areas. The cross-voxel correlations between the frequency and overall ReHo were negative in all the brain areas but varied from region to region. These correlations were stronger with EO in the visual network and the default mode network. Our results suggested that different frequency bands of ReHo showed different sensitivity to the modulation of EO-EC states. The better spatial consistency between the frequency and overall ReHo maps indicated that the brain might adopt a stricter frequency-dependent configuration with EO than with EC.

    The electroencephalogram (EEG) signal represents a subject's specific brain activity patterns and is considered as an ideal biometric given its superior forgery prevention. However, the accuracy and stability of the current EEG-based person authentication systems are still unsatisfactory in practical application. In this paper, a multi-task EEG-based person authentication system combining eye blinking is proposed, which can achieve high precision and robustness. Firstly, we design a novel EEG-based biometric evoked paradigm using self- or non-self-face rapid serial visual presentation (RSVP). The designed paradigm could obtain a distinct and stable biometric trait from EEG with a lower time cost. Secondly, the event-related potential (ERP) features and morphological features are extracted from EEG signals and eye blinking signals, respectively. Thirdly, convolutional neural network and back propagation neural network are severally designed to gain the score estimation of EEG features and eye blinking features. Finally, a score fusion technology based on least square method is proposed to get the final estimation score. The performance of multi-task authentication system is improved significantly compared to the system using EEG only, with an increasing average accuracy from 92.4% to 97.6%. Moreover, open-set authentication tests for additional imposters and permanence tests for users are conducted to simulate the practical scenarios, which have never been employed in previous EEG-based person authentication systems. A mean false accepted rate (FAR) of 3.90% and a mean false rejected rate (FRR) of 3.87% are accomplished in open-set authentication tests and permanence tests, respectively, which illustrate the open-set authentication and permanence capability of our systems.

    Fireworks combusted during New Year's Eve festivities can cause different eye traumas which often need complex reconstructive surgery. It was our aim to systematically analyse these eye trauma cases which were treated at our clinic during the last eight years. Age, gender, side, trauma mechanism, treatment methods and outcome were analysed for all eye trauma cases caused by fireworks during the New Year's Eve celebrations from 2006 to 2013. For statistical analysis all trauma cases were divided into two groups of major and non-major eye trauma. The total number of patients treated was 122 (28 women, 94 men, mean age 26.2±13.0 years) with 137 traumatised eyes (77 right, 60 left). 24.6% of patients were ≤18 years of age. 76.2% were bystanders. 50 eyes from 46 patients (37.7%) suffered from major eye trauma. 26 patients (21.3%) were hospitalised. 8 eyes (5.8%) suffered from a penetrating injury or globe rupture and underwent primary reconstructive surgery. Further 16 eyes (11.7%) suffered from major eye trauma without open globe injury. In the aftermath 11 eyes (8.0%) went blind (visual acuityfireworks. However older patients suffer from major eye trauma more often. More education and prophylaxis of eye trauma caused by fireworks is desirable. Georg Thieme Verlag KG Stuttgart · New York.

    Thanks to the efforts of the various globe digitising projects, nowadays there are plenty of old globes that can be examined as 3D models on the computer screen. These globes usually contain a lot of interesting details that an average observer would not entirely discover for the first time. The authors developed a website that can display annotations for such digitised globes. These annotations help observers of the globe to discover all the important, interesting details. Annotations consist of a plain text title, a HTML formatted descriptive text and a corresponding polygon and are stored in KML format. The website is powered by the Cesium virtual globe engine.

    This study focuses on a novel, easy to use and instruction-less method for mental training in athletes. Previous findings suggest that particular mental capacities are needed for achieving peak performance; including attentional control, focus, relaxation and positive affect. Electroencephalography (EEG) alpha brain activity has been associated with neural inhibition during processes of selective attention, for improving efficiency in information processing. Here we hypothesised that eyes open alpha power training by music teaches athletes to (1) learn to self-regulate their brain activity, and (2) learn to increase their baseline alpha power, herewith improving mental capacities such as focusing the allocation of attention. The study was double-blind and placebo-controlled. Twelve elite gymnasts were either given eyes open alpha power training or random beta power training (controls). Results indicate small improvements in sleep quality, mental and physical shape. In our first attempt at getting a grip on mental capacities in athletes, we think this novel training method can be promising. Because gymnastics is one of the most mentally demanding sports, we value even small benefits for the athlete and consider them indicative for future research.

  9. A Study of Deep CNN-Based Classification of Open and Closed Eyes Using a Visible Light Camera Sensor

    2017-06-01

    Full Text Available The necessity for the classification of open and closed eyes is increasing in various fields, including analysis of eye fatigue in 3D TVs, analysis of the psychological states of test subjects, and eye status tracking-based driver drowsiness detection. Previous studies have used various methods to distinguish between open and closed eyes, such as classifiers based on the features obtained from image binarization, edge operators, or texture analysis. However, when it comes to eye images with different lighting conditions and resolutions, it can be difficult to find an optimal threshold for image binarization or optimal filters for edge and texture extraction. In order to address this issue, we propose a method to classify open and closed eye images with different conditions, acquired by a visible light camera, using a deep residual convolutional neural network. After conducting performance analysis on both self-collected and open databases, we have determined that the classification accuracy of the proposed method is superior to that of existing methods.

    Full Text Available A life course perspective, drawing on historical and personal experiences, is used to identify eye-opening concepts that can be used to make sense of the world in terms of personal and social ageing, in the context of intergenerational relationships. Two issues have been identified that characterise a challenge to cultural adaptation: that of generations increasingly becoming approximately the same size as they move from demographic triangles to columns, and that of finding an age-specific purpose for a long life. An analysis of contemporary problems facing gerontology and social policy is given, drawing on the need for complementary life priorities and enhanced generational intelligence. Implications for work, generational rivalry and precarity are examined along with some conclusions on the role of eyeopening conceptual development.

    To evaluate intraocular pressure (IOP) change after cataract surgery in eyes with open-angle glaucoma (OAG) and its relationship to angle and anterior segment parameters measured by anterior segment optical coherence tomography (AS-OCT). University of California, San Francisco, California, USA. Prospective case series. Eyes were placed into a narrow-angle group or open-angle group based on gonioscopy grading. Biometric parameters were measured using AS-OCT (Visante) preoperatively, and IOP 4 months after surgery was obtained. The IOP change and its relationship to AS-OCT parameters were evaluated. Eighty-one eyes of 69 patients were enrolled. The mean age of the patients was 76.8 years. The preoperative IOP was 15.02 mm Hg on 1.89 glaucoma medications. The average mean deviation of preoperative visual field was -4.58 dB. The mean IOP reduction was 2.1 mm Hg (12.8%) from a preoperative mean of 15.0 mm Hg. The IOP reduction was significantly greater in eyes with narrow angles than in eyes with open angles (20.4% versus 8.0%) (P = .002). In multivariate analysis, preoperative IOP (β = -0.53, P < .001, R 2  = 0.40), angle-opening distance at 500 mm (β = 5.83, P = .02, R 2  = 0.45), angle-opening distance at 750 mm (β = 5.82, P = .001, R 2  = 0.52), and lens vault (β = -0.002, P = .009, R 2  = 0.47) were associated with IOP reduction postoperatively. In eyes with OAG, IOP reduction after cataract surgery was greater in eyes with narrower angles. Preoperative IOP, angle-opening distance, and lens vault were predictors for IOP reduction.

    Full Text Available The purpose of the study is to develop a comprehensive treatment aimed at improving uveoscleral outflow in the application of dynamic laser magnetic stimulation of the drainage system of the eye and evaluation of its effectiveness in treating patients with primary open-angle glaucoma (POAG. Material. 106 patients diagnosed POAG I, II, III stages were examined. Group 1 consisted of 62 patients treated with medical therapy and dynamic laser magnetic stimulation of the drainage system of the eye using the "AMO-ATOS-ICL", produced by JSC "TRIMA", Saratov. Group 2 consisted of 64 patients who received only medical therapy. Comprehensive survey including standard eye examination, static perimetry, visual evoked potentials study, the study of intraocular blood flow was conducted to all patients. Analysis of the results of the complex therapeutic effects showed that as the result of treatment 73% of patients had a decrease of intraocular pressure and the ease factor outflow increase. 52% of patients had a decrease in the number and area of relative. 63% of patients had activation of intraocular blood flow. These indices remained stable for three months. Conclusion. The treatment with the technique of dynamic laser magnetic stimulation of the drainage system of the eye of patients with primary open-angle glaucoma leads to lower intraocular pressure, and to the improvement of dopple-rographic and perimetric indications.

    Full Text Available Purpose: The purpose of this study was to document clinical findings and management of a patient with bilateral globe luxation and optic nerve transection. Materials and Methods: A 25-year-old female patient was admitted to the emergency department with bilateral traumatic globe luxation following a motor vehicle accident. Results: Visual acuity testing showed no light perception. The right pupil was dilated and bilaterally did not react to light. The globes were bilaterally intact. A computed tomography scan revealed Le Fort type II fractures, bilateral optic nerve transection and disruption of all extraocular muscles. The globes of the patient were bilaterally reduced into the orbit. However, the patient developed phthisis bulbi in the right eye at month 3. Conclusion: Globe luxation presents a dramatic clinical picture, and may lead to the development of severe complications due to the concomitance of complete optic nerve dissection and multiple traumas. Even if the luxated globe is repositioned into the orbit, there is still an increased risk of the development of phthisis due to ischemia.

  20. Brain spontaneous fluctuations in sensorimotor regions were directly related to eyes open and eyes closed: evidences from a machine learning approach

    Directory of Open Access Journals (Sweden)

    2014-08-01

    Full Text Available Previous studies have demonstrated that the difference between resting-state brain activations depends on whether the subject was eyes open (EO or eyes closed (EC. However, whether the spontaneous fluctuations are directly related to these two different resting states are still largely unclear. In the present study, we acquired resting-state functional magnetic resonance imaging data from 24 healthy subjects (11 males, 20.17 ± 2.74 years under the EO and EC states. The amplitude of the spontaneous brain activity in low-frequency band was subsequently investigated by using the metric of fractional amplitude of low frequency fluctuation (fALFF for each subject under each state. A support vector machine (SVM analysis was then applied to evaluate whether the category of resting states could be determined from the brain spontaneous fluctuations. We demonstrated that these two resting states could be decoded from the identified pattern of brain spontaneous fluctuations, predominantly based on fALFF in the sensorimotor module. Specifically, we observed prominent relationships between increased fALFF for EC and decreased fALFF for EO in sensorimotor regions. Overall, the present results indicate that a SVM performs well in the discrimination between the brain spontaneous fluctuations of distinct resting states and provide new insight into the neural substrate of the resting states during EC and EO.

    The GLOBE Mosquito Larvae protocol and a new citizen science initiative, GLOBE Observers (GO), were both launched in Summer 2016. While the GLOBE Mosquito Larvae Protocol and associated educational materials target K-16 student inquiry and research, the GO protocol version is simplified to enable citizen scientists of all ages from all walks of life to participate. GO allows citizen scientists to collect and submit environmental data through an easy-to-use smart phone app available for both Apple and Android mobile devices. GO mosquito asks for photos of larvae mosquito genus or species, location, and type of water source (e.g., container or pond) where the larvae were found. To initiate the new mosquito GLOBE/GO opportunities, workshops have been held in Barbuda, Thailand, West Indies, US Gulf Coast, New York City, and at the GLOBE Annual Meeting in Colorado. Through these venues, the protocols have been refined and a field campaign has been initiated so that GO and GLOBE citizen scientists (K-16 students and all others) can contribute data. Quality assurance measures are taken through the online training required to participate and the validation of identification by other citizen sciences and mosquito experts. Furthermore, initial research is underway to develop optical recognition software starting with the species that carry the Zika virus (Aedes aegypti and A. albopictus). With this launch, we plan to move forward by providing opportunities throughout the world to engage people in meaningful environmental and public health data collection and to promote citizen scientists to become agents of change in their communities.

    We report the results of an experimental study of the effect of short-pulse laser UV radiation on the eye scleral tissue. As samples, we used isolated flaps of the eye scleral tissue from the patients with open-angle glaucoma of the second and third stages. The impact was implemented using the radiation of an excimer XeCl laser with a wavelength of 308 nm and a laser with a wavelength tunable within from 210 to 355 nm. Depending on the problem to be solved, the energy density on the surface of the irradiated tissue varied from a fraction of mJ cm-2 to 15 J cm-2. For the first time we studied the optical properties of the intraocular fluid in the UV and blue spectral range. The study of the ablation process under the action of radiation with a wavelength of 308 nm showed that the rate of material evaporation can vary within 24%–30% at an energy density above 7 J cm-2, depending on the glaucoma stage and the individual features of a patient. The excitation–emission matrices of laser-induced fluorescence (LIF) of the eye scleral tissue were studied experimentally using a laser with a wavelength tuned in the range 210–355 nm. We found the differences in the LIF spectra caused by the excitation wavelength and the openangle glaucoma stage.

    2012-06-01

    Full Text Available Abstract Background An eye injury that causes no light perception (NLP typically carries an unfavorable prognosis, and NLP because of trauma is a common indication for enucleation. With advances in vitreoretinal surgical techniques, however, the indication for enucleation is no longer determined by posttrauma NLP vision alone. There are limited studies in the literature to analyse the outcome of NLP eyes following open globe injury. The current study was aimed to evaluate the outcome of surgical repair of severely traumatized eyes with no light perception vision as preoperative visual acuity. Secondary objective was to possibly predict the factors affecting the final vision outcome in this eyes. Methods Retrospective case analysis of patients with surgical repair of open globe injury over last ten years at a tertiary referral eye care centre in Singapore. Results Out of one hundred and seventy two eyes with open globe injury 27 (15.7% eyes had no light perception (NLP. After surgical repair, final visual acuity remained NLP in 18 (66.7% eyes. Final vision improved to Light perception/ Hand movement (LP/HM in 2(7.4% eyes, 1/200 to 19/200(11.1% in 3 eyes and 20/50-20/200(14.8% in 4 eyes. The median follow up was 18.9 months (range: 4–60 months. The factors contributing to poor postoperative outcome were presence of RAPD (p = 0.014, wound extending into zone III (p = 0.023 and associated vitreoretinal trauma (p = 0.008. Conclusions One third of eyes had ambulatory vision or better though two third of eyes still remained NLP. Pre-operative visual acuity of NLP should not be an indication for primary enucleation or evisceration for severely traumatized eyes. Presence of afferent papillary defect, wound extending posterior to rectus insertion and associated vitreoretinal trauma can adversely affect the outcome in severely traumatized eyes with NLP. Timely intervention and state of art surgery may restore useful vision in severely

    To examine the morphology of Bruch's membrane opening (BMO), optic disc, and peripapillary atrophy (PPA) by scanning laser ophthalmoscopy (SLO) and spectral-domain optical coherence tomography (SD-OCT), and to determine their association with the axial length and visual field defects. This was a cross-sectional study of 94 eyes of 56 subjects; 77 eyes were diagnosed with primary open-angle glaucoma and 17 eyes as normal. The margins of the optic disc were determined in the SLO images, and that of the BMO in the SD-OCT images. The ovality and area of the BMO and the optic disc were measured. The beta and gamma-PPA areas were also measured. The association of each parameter with the axial length and the mean deviation (MD) of the visual field tests was determined by generalized estimating equations (GEEs). The optic disc ovality was associated with the axial length and the MD (β = -0.47, P = 7.6 × 10 -4 and β = 0.12, P = 0.040). The BMO ovality was not significantly associated with the axial length and the MD. The BMO area was associated with the axial length (β = 0.30, P = 0.029). A larger BMO area was associated with a thinner BMO-based neuroretinal rim width (BMO-MRW) after adjustments for the MD (β = -0.30, P = 2.1 × 10 -4 ). The beta- and gamma-PPA areas were associated with the axial length (β = 0.50, P = 7.4 × 10 -5 and β = 0.62, P = 4.2 × 10 -6 ). The optic disc ovality was associated with both the axial length and MD, whereas BMO ovality was not. Attention should be paid to the influence of the axial length-related enlargement of the BMO.

    Full Text Available Based on what you found during the eye examination, classify the injury as a non-mechanical injury (chemical or thermal injury, a non-globe injury (orbital or adnexal injury or as a mechanical globe injury. In the case of mechanical globe injuries, it is important to classify the injury according to the Birmingham Eye Trauma Terminology System (BETTS and write it down in the patient’s notes; this will help to ensure that everyone involved in caring for the patient will have a consistent understanding of the type of injury. The resulting uniformity of terminology also helps with research, making it possible to compare data and do audits of injuries – which is essential for prevention.

    2016-12-01

    Ten years ago, Google Earth was new, and the first "Virtual Globes" session was held at AGU. Only a few of us realized the potential of this technology at the time, but the idea quickly caught on. At that time a virtual globe came in two flavors, first a complex GIS system that was utterly impenetrable for the public, or a more accessible version with limited functionality and layers that was available on a desktop computer with a good internet connection. Google Earth's use of the Keyhole Markup Language opened the door for scientists and the public to share data and visualizations across disciplines and revolutionized how everyone uses geographic data. In the following 10 years, KML became more advanced, virtual globes moved to mobile and handheld platforms, and the Google Earth engine allowed for more complex data sharing among scientists. Virtual globe images went from a rare commodity to being everywhere in our lives, from weather forecasts, in our cars, on our smart-phones and shape how we receive and process data. This is a fantastic tool for education and with newer technologies can reach the the remote corners of the world and developing countries. New and emerging technologies allow for augmented reality to be merged with the globes, and for real-time data integration with sensors built into mobile devices or add-ons. This presentation will follow the history of virtual globes in the geosciences, show how robust technologies can be used in the field and classroom today, and make some suggestions for the future.

    The GLOBE Program is a worldwide science and education partnership endeavor designed to increase scientific understanding of Earth as a system, support improved student achievement in science and math, and enhance environmental awareness through inquiry-based learning activities. GLOBE began on the premise that teachers and their students would partner with scientists to collect and analyze environmental data using specific protocols in five study areas - atmosphere, soils, hydrology, land cover, and phenology. As the GLOBE network grew, additional partnerships flourished making GLOBE an unprecedented collaboration of individuals worldwide - primary, secondary, and tertiary students, teachers and teacher educators, scientists, government officials, and others - to improve K-12 education. Since its inception in 1994, more than one million students in over 14,000 schools around the world have taken part in The GLOBE Program. The GLOBE Web site (http://www.globe.gov) is the repository for over 11 million student-collected data measurements easily accessible to students and scientists worldwide. Utilizing the advantages of the Internet for information sharing and communication, GLOBE has created an international community. GLOBE enriches students by giving them the knowledge and skills that they will need to become informed citizens and responsible decision-makers in an increasingly complex world. Understanding that all members of a community must support change if it is to be sustainable, GLOBE actively encourages the development of GLOBE Learning Communities (GLCs) which are designed to get diverse stakeholder groups involved in a local or regional environmental issue. Central to the GLC is the engagement of local schools. GLCs go beyond individual teachers implementing GLOBE in the isolation of their classrooms. Instead, the GLC brings multiple teachers and grade levels together to examine environmental issues encouraging the participation of a broad range of

    This study compared the efficacy, safety, and pharmacokinetics of a preservative-free latanoprost formulation to an established, benzalkonium chloride (BAK) containing formulation for the treatment of open-angle glaucoma or ocular hypertension. This was a phase II, randomized, cross-over, investigator-masked, multi-center, pilot study (NCT01494753). A total of 30 untreated adult patients (aged ≥18 years) with primary open angle glaucoma, pseudo-exfoliative glaucoma, pigmentary glaucoma, or ocular hypertension received either preservative-free or preserved latanoprost once daily in both eyes for 6 weeks, before crossing over to receive the other treatment. Efficacy (intraocular pressure [IOP] at 8 am, midday, 4 pm and 8 pm, and global efficacy assessment by investigator), safety (adverse events, ocular symptoms and global tolerance, slit lamp examination, funduscopy, visual field examination, visual acuity, and heart rate), and pharmacokinetics were assessed at Days 0, 42, and 84. Both treatments resulted in a reduction in IOP that was similar for the preservative-free and the preserved formulation at all time points. Similarly, the overall diurnal reduction was similar in both groups (6.3 mmHg [27.9% reduction] and 6.4 mmHg [28.1% reduction] for preserved and preservative-free latanoprost, respectively). There were no differences in global efficacy assessment or in the safety and tolerance of each treatment. Systemic concentrations of latanoprost were very low; AUC0-30 and Cmax were lower and tmax was longer for preservative-free latanoprost. Preservative-free latanoprost showed similar efficacy at all time points compared to BAK preservative containing formulation, with no difference in tolerance, allowing progression to phase III clinical development.

  17. Experience-dependent plasticity from eye opening enables lasting, visual cortex-dependent enhancement of motion vision.

    2008-09-24

    Developmentally regulated plasticity of vision has generally been associated with "sensitive" or "critical" periods in juvenile life, wherein visual deprivation leads to loss of visual function. Here we report an enabling form of visual plasticity that commences in infant rats from eye opening, in which daily threshold testing of optokinetic tracking, amid otherwise normal visual experience, stimulates enduring, visual cortex-dependent enhancement (>60%) of the spatial frequency threshold for tracking. The perceptual ability to use spatial frequency in discriminating between moving visual stimuli is also improved by the testing experience. The capacity for inducing enhancement is transitory and effectively limited to infancy; however, enhanced responses are not consolidated and maintained unless in-kind testing experience continues uninterrupted into juvenile life. The data show that selective visual experience from infancy can alone enable visual function. They also indicate that plasticity associated with visual deprivation may not be the only cause of developmental visual dysfunction, because we found that experientially inducing enhancement in late infancy, without subsequent reinforcement of the experience in early juvenile life, can lead to enduring loss of function.

    2018-01-01

    Background Little attention has been given to in-depth examination of what high-fidelity simulation is like for nursing students within the context of a pediatric emergency, such as a cardiopulmonary arrest. It is possible that such high-fidelity simulation could provoke in nursing students intense psychological reactions. Purpose The purpose of this study was to learn about baccalaureate nursing students' lived experience of high-fidelity simulation of pediatric cardiopulmonary arrest. Method Phenomenological methods were used. Twenty-four interviews were conducted with 12 students and were analyzed for themes. Results The essence of the experience is that it was eye-opening. The students found the simulation to be a surprisingly realistic nursing experience as reflected in their perceiving the manikin as a real patient, thinking that they were saving their patient's life, feeling like a real nurse, and feeling relief after mounting stress. It was a surprisingly valuable learning experience in that the students had an increased awareness of the art and science of nursing and increased understanding of the importance of teamwork and were feeling more prepared for clinical practice and wanting more simulation experiences. Conclusion Educators should capitalize on the benefits of high-fidelity simulation as a pedagogy, while endeavoring to provide psychologically safe learning.

    Eco-neighbourhoods, solar panels, recycled heat: these were just some of the innovative ecological projects presented at the panel discussion organised by the Commune of Meyrin at the Globe on Thursday 21 June. CERN is closely involved with several of the projects.   CERN has an important role to play in sustainable development, and in Meyrin it has an excellent local partner. This was perhaps the key message, from CERN’s point of view, to come out of Thursday’s event. It particularly highlighted the proposed plan to use part of the “waste” heat going to the cooling towers at Point 1 to contribute to heating Meyrin’s new ecological housing project, Les Vergers. Some of CERN’s other high-profile contributions to sustainable development, such as the solar panels using CERN vacuum technology on the airport roof, were also presented.

    A systematic soil survey of Belgium was conducted from 1948 to 1991. Field surveys were done at the detailed scale of 1:5000 with the final maps published at a 1:20,000 scale. The legend of these detailed soil maps (scale 1:20,000) has been converted to the 3rd edition of the international soil classification system 'World Reference Base for Soil Resources' (WRB). Over the last years, the government of the Flemish region made great efforts to make these maps, along with other environmental data, available to the general audience through the internet. The soil maps are widely used and consulted by researchers, teachers, land-use planners, environmental consultancy agencies and archaeologists. The maps can be downloaded and consulted in the viewer 'Visual Soil Explorer' ('Bodemverkenner'). To increase the legibility of the maps, we assembled a collection of photographs from soil profiles representing 923 soil types and 413 photos of related landscape settings. By clicking on a specific location in the 'Visual Soil Explorer', pictures of the corresponding soil type and landscape appear in a pop-up window, with a brief explanation about the soil properties. The collection of photographs of soil profiles cover almost 80% of the total area of the Flemish region, and include the 100 most common soil types. Our own teaching experience shows that these information layers are particular valuable for teaching soil geography and earth sciences in general. Overall, such visual information layers should contribute to a better interpretation of the soil maps and legacy soil data by serving as an eye-opener on the soil map to the wider community.

    The eye is a complex structure composed of several interconnected tissues acting together, across the whole globe, to resist deformation due to intraocular pressure (IOP). However, most work in the ocular biomechanics field only examines the response to IOP over smaller regions of the eye. We used high-field MRI to measure IOP induced ocular displacements and deformations over the whole globe. Seven sheep eyes were obtained from a local abattoir and imaged within 48 h using MRI at multiple levels of IOP. IOP was controlled with a gravity perfusion system and a cannula inserted into the anterior chamber. T2-weighted imaging was performed to the eyes serially at 0 mmHg, 10 mmHg, 20 mmHg and 40 mmHg of IOP using a 9.4 T MRI scanner. Manual morphometry was conducted using 3D visualization software to quantify IOP-induced effects at the globe scale (e.g. axial length and equatorial diameters) or optic nerve head scale (e.g. canal diameter, peripapillary sclera bowing). Measurement sensitivity analysis was conducted to determine measurement precision. High-field MRI revealed an outward bowing of the posterior sclera and anterior bulging of the cornea due to IOP elevation. Increments in IOP from 10 to 40 mmHg caused measurable increases in axial length in 6 of 7 eyes of 7.9 ± 5.7% (mean ± SD). Changes in equatorial diameter were minimal, 0.4 ± 1.2% between 10 and 40 mmHg, and in all cases less than the measurement sensitivity. The effects were nonlinear, with larger deformations at normal IOPs (10-20 mmHg) than at elevated IOPs (20-40 mmHg). IOP also caused measurable increases in the nasal-temporal scleral canal diameter of 13.4 ± 9.7% between 0 and 20 mmHg, but not in the superior-inferior diameter. This study demonstrates that high-field MRI can be used to visualize and measure simultaneously the effects of IOP over the whole globe, including the effects on axial length and equatorial diameter, posterior sclera displacement and bowing, and even

    Orbis World Globes creates inflatable globes-Earthballs-in many sizes that depict Earth as it is seen from space, complete with atmospheric cloud cover. Orbis designs and produces the most visually authentic replicas of Earth ever created, and NASA took notice of Orbis globes and employed a 16-inch diameter EarthBall for an educational film it made aboard the STS-45 shuttle mission. Orbis later collaborated with NASA to create two 16-foot diameter world globes for display at the 2002 Olympic Winter Games in Salt Lake City, using more detailed satellite imagery. The satellite image now printed on all Orbis globes displays 1-kilometer resolution and is 21,600 by 43,200 pixels in size, and Orbis globes are otherwise meteorologically accurate, though the cloud cover has been slightly reduced in order for most of the landforms to be visible. Orbis also developed the exclusive NightGlow Cities feature, enabling EarthBalls to display the world's cities as they appear as the Earth revolves from daylight into night. Orbis inflatable globes are available in sizes from 1 to 100 feet in diameter, with the most common being the standard 16-inch and 1-meter diameter EarthBalls. Applications include educational uses from preschools to universities, games, and for a variety of display purposes at conferences, trade shows, festivals, concerts, and parades. A 16-foot diameter Orbis globe was exhibited at the United Nations' World Urban Forum, in Vancouver, Canada; the Space 2006 conference, in San Jose, California; and the X-Prize Cup Personal Spaceflight Exposition in Las Cruces, New Mexico.

  17. Psoriasis: an eye opener – a cross-sectional study in a Tertiary Care Hospital of South India

    Directory of Open Access Journals (Sweden)

    Hari Kishan Kumar Yadalla

    2015-01-01

    Full Text Available Introduction: Psoriasis is a multi-system chronic inflammatory skin disease targeting 2% to 3% of the general population. It is a prototype of immune dysregulation mediated by TH1 proinflammatory cytokines such as TNF-α, IFN-gamma, IL-6, and IL-12 with far reaching systemic effects. There is growing and emerging evidence that psoriasis patients have a higher prevalence of associated comorbid diseases, with severe skin disease portends a serious risk for development of these comorbidities and are found to have a higher association of extracutaneous disease manifestations. Aim: To look for eye involvement in psoriasis patients and to evaluate the risk and prognostic factors of disease association. Material and Methods: 200 Patients with psoriasis were screened for any eye involvement after few unusual case presentations with eye complications during the period from September 2013 - August 2014. Results: First case was a post cataract sudden loss of vision secondary to development of uveitis in a female patient aged 52 years, with past history of psoriasis with minimal skin lesions and no arthritis. Another 5 cases of psoriasis with eye involvement were detected during the screening employed in a series of 200 psoriasis cases. Conclusion: The present report highlights the importance of psoriasis and eye involvement, need for collaboration between dermatologists and ophthalmologists for thorough examination and evaluation prior to any surgical intervention and also further long term follow-up studies are warranted for confirmation of this causal relationship.

  18. Closed-eye orbital prosthesis: a clinical report.

    2015-03-01

    One of the most challenging prostheses to fabricate is an acceptable orbital prosthesis. Successful reconstruction of the complex missing tissues, the globe, muscle, skin, and bony elements requires time and high levels of practical skill. A good match to the contralateral nondefect side will help mask the underlying defect and give the patient confidence to return to normal, routine life. The contralateral eye opening will commonly dictate the eye opening of such a prosthesis, but because of the expressive nature of the eye and its high levels of mobility, this can be difficult to achieve. This clinical report presents a patient who had an extended orbital exenteration and right maxillectomy to remove a maxillary squamous cell carcinoma. An alternative approach to constructing an orbital prosthesis was undertaken with the eye closed. Compared to the normal method of fabrication, this process was less complex and quicker, made the prosthesis less "staring," camouflaged the defect, and reduced the detection of the prosthesis because of movements in the remaining eye. The patient engaged in his routine daily life, which reinforced his self-esteem, confidence, and reintegration into the community.

    2015-01-01

    To analyse the demographic data, clinical characteristics, management and prognosis of patients with firework-related eye injuries. A retrospective review was performed of patients with eye injuries related to fireworks referred to TianJin Eye Hospital in North China from 2008 to 2013. Demographic information, clinical features, management and visual outcome were analysed and prognosis factors were evaluated. Ninety-nine patients (86 men) with 118 eye injuries were enrolled in the study. The average age of the patients was 32.0±20.5 years; 70/99 (70.7%) were aged >20 years. Eighty-one of the patients had been lighting the fireworks while the rest were bystanders. The main ophthalmic manifestations were hyphaema, vitreous haemorrhage, corneal/sclera/corneoscleral open globe injury, eyelid laceration, traumatic cataract, retinal/choroid detachment, endophthalmitis and intraocular foreign body (IOFB). Ninety patients required surgical intervention including repair of open globe injury, vitrectomy, cataract extraction and enucleation. 56/118 eyes (47.5%) received multiple operations. After treatment, final best-corrected visual acuity (BCVA) significantly improved (p=0.015). Some factors were significantly correlated with better final BCVA, including initial BCVA (p=0.036), closed globe injury (p=0.031), absence of endophthalmitis (p=0.014), absence of IOFB (p=0.024) and absence of retinal detachment (p=0.046). Firework-related eye injuries mainly occur in adult men and result in severe visual damage. The most common clinical manifestations are hyphaema and vitreous haemorrhage. Better initial BCVA and closed globe injury have a better visual result while endophthalmitis, IOFB and retinal detachment have a negative visual outcome. Improved eye protection, along with enhanced public education and legal ban on fireworks, could reduce the incidence of eye injuries. Published by the BMJ Publishing Group Limited.

    Primary open angle glaucoma is an insidious and chronic vision-threatening eye ailment due to neuro-retino-optic nerve degeneration, which may be due to the raised intraocular pressure (IOP) or due to independent factors. Management of glaucoma is mainly concentrated on lowering IOP that requires lifetime topical medication, different ocular medicaments for lowering of IOP, and surgical interventions, but it has its own limitations to control the progression of glaucomatous optic neuropathy (GON), and this is the reason behind the use of alternative neuroprotective adjuvants. To evaluate the neuroprotective effect of Ayurvedic line of management of progressive GON. Ingredients of trial drug Vara Fort powder ( Chakshushya Rasayana ) were procured from the Institute Pharmacy, except Swarnamakshika Bhasma , which was purchased from Dhootapapeshwar Pharmaceuticals. The patients fulfilling inclusion criteria, attending outpatient and inpatient departments, irrespective of their sex, race, religion, occupation, etc., were selected and divided into two groups with open-labeled randomization. In Group A, in addition to betaxolol (0.1%) or timolol (0.5%) (non-iobrim), Chakshushya Rasayana 6 g/day orally with Triphala Ghrita and honey along with Koshtha-Shuddhi (body-microchannel clearing treatment) protocol was tried. Nasya (oleation through nasal route) with Jeevantyadi Taila and Tarpana (eye satiation) with Go-Ghrita were also performed. In Group B (control), brimonidine (iobrim) 0.2% eye drop was used for 3 months. Significant improvement was observed in subjective parameters in Group A such as blurred vision, frequent change of presbyopic glasses, and delayed dark adaptation. Chakshushya Rasayana , if administered in a systematic approach along with a modern topical betaxolol or timolol eye drops, has a definite role in improving the lost retinal sensitivity as much as up to 12 dB in 3 months duration.

    Ocular injuries from blast have increased in recent wars, but the injury mechanism associated with the primary blast wave is unknown. We employ a three-dimensional fluid-structure interaction computational model to understand the stresses and deformations incurred by the globe due to blast overpressure. Our numerical results demonstrate that the blast wave reflections off the facial features around the eye increase the pressure loading on and around the eye. The blast wave produces asymmetric loading on the eye, which causes globe distortion. The deformation response of the globe under blast loading was evaluated, and regions of high stresses and strains inside the globe were identified. Our numerical results show that the blast loading results in globe distortion and large deviatoric stresses in the sclera. These large deviatoric stresses may be indicator for the risk of interfacial failure between the tissues of the sclera and the orbit.

  6. The Optic Nerve Head in Primary Open-Angle Glaucoma Eyes With High Myopia: Characteristics and Association With Visual Field Defects.

    Chen, Li-Wei; Lan, Yu-Wen; Hsieh, Jui-Wen

    2016-06-01

    To evaluate the morphologic characteristics of optic neuropathy and its association with visual field (VF) defects in primary open-angle glaucoma (POAG) eyes with high myopia. In this cross-sectional study, we reviewed data from 375 Taiwanese patients (375 eyes) of POAG, ages 20 to 60 years. Optic disc photographs were used for planimetric measurements of morphologic variables. The myopic refraction was divided into high myopia (<-6.0 D) and nonhigh myopia (moderate myopia to hyperopia). The optic disc area was classified as moderate (1.59 to 2.85 mm), large, and small. Differences in characteristics between groups, correlations with the disc area, and factors associated with VF defects were determined. Of the 142 highly myopic eyes, 33 (23%) had a large disc, 26 (18%) had a small disc, and 55 (39%) had a tilted disc. Large discs had a higher cup-to-disc (C/D) area ratio and a higher tilt ratio; small discs had a smaller rim area and a lower tilt ratio (all P<0.05). Characteristics associated with high myopia included a smaller rim area, a higher C/D area ratio, and a lower tilt ratio (all P<0.001). In logistic regression, the refraction, the C/D area ratio, the rim area, and the tilt ratio (all P<0.05) were associated with VF defects. In Taiwanese individuals with POAG, our study found that tilted, large, or small discs were prevalent in highly myopic eyes. Of these characteristics, only the disc tilt and high myopia by itself were associated with the severity of glaucomatous optic neuropathy.

    To assess if narrower-angle status and anterior segment optical coherence tomography (AS-OCT) parameters can predict intraocular pressure (IOP) drop in primary open-angle glaucoma (POAG) patients after cataract surgery. This was a prospective case series of consecutive cataract surgery patients with POAG and no peripheral anterior synechiae (PAS) using a standardized postoperative management protocol. Preoperatively, patients underwent gonioscopy and AS-OCT. The same glaucoma medication regimen was resumed by 1 month. Potential predictors of IOP reduction included narrower-angle status by gonioscopy and angle-opening distance (AOD500) as well as other AS-OCT parameters. Mixed-effects regression adjusted for use of both eyes and other potential confounders. We enrolled 66 eyes of 40 glaucoma patients. The IOP reduction at 1 year was 4.2±3 mm Hg (26%, P gonioscopy. By AOD500 classification, the narrower-angle group had 3.4±3 mm Hg (21%, P <.001) reduction vs 2.5±3 mm Hg (16%, P <.001) in the wide-angle group ( P =.031 for difference). When the entire cohort was assessed, iris thickness, iris area, and lens vault were correlated with increasing IOP reduction at 1 year ( P <.05 for all). In POAG eyes, cataract surgery lowered IOP to a greater degree in the narrower-angle group than in the wide-angle group, and parameters relating to iris thickness and area, as well as lens vault, were correlated with IOP reduction. These findings can guide ophthalmologists in their selection of cataract surgery as a potential management option.

  9. The Globe of Innovation takes shape

    CERN Multimedia

    2004-01-01

    On 18 May, the central vortex of the CERN Globe of Innovation was put into place more than 22 metres above the ground. The central vortex of the Globe of Innovation is a crown measuring 6.15 metres in diameter and 4.5 meters in height. Having been lifted by a crane to a height of over 22 metres, the vortex is placed on a support structure which will be removed once the 36 arcs providing the building's structure have been secured in place. Resting some 22 metres above the ground, the central vortex of the Globe of Innovation is now ready to support the 36 wooden arcs which will provide the building's structure. Work to reassemble the former Palais de l'Equilibre, which was first erected in Neuchâtel for the EXPO.02 exhibition, began on 18 May. The sphere, measuring 40 metres in diameter, has now been renamed the Globe of Innovation. A detachment from the Swiss army is carrying out the work, which will be completed in time for the Organization's official fiftieth anniversary celebrations. The building will be...

    "Draw Me A Physicist" has been a success. Members of the public visiting the exhibition in the Globe of Science and Innovation have praised the scientific and creative balance the children of neighbouring France and the Canton of Geneva have obtained through their visit to CERN.   The Draw Me a Physicist exhibition in the Globe For a six-month period 9 to 11-year olds from the Pays de Gex, Meyrin, Satigny and Vernier have been able to enjoy a balance between science and art, through drawing and defining their interpretations of a physicist. In May, eight pairs of drawings from each participating class were selected by the schools to be displayed on the second floor of the Globe. Since the images have been put up, the viewers have enjoyed the contrast between the "before" pictures of vibrant Albert Einsteins to the "after" pictures of casual people sitting in an office. The large room in the Globe has been transformed from a hollow shell int...

  12. Science Outreach in Virtual Globes; Best Practices

    Science.gov (United States)

    Treves, R. W.

    2007-12-01

    The popularity of projects such as 'Crisis in Darfur' and the IPY (International Polar Year) network link show the potential of using the rich functionality of Virtual Globes for science outreach purposes. However, the structure of outreach projects in Virtual Globes varies widely. Consider an analogy: If you pick up a science journal you immediately know where to find the contents page and what the title and cover story are meant to communicate. That is because journals have a well defined set of norms that they follow in terms of layout and design. Currently, science projects presented in virtual globes have, at best, weakly defined norms, there are little common structural elements beyond those imposed by the constraints of the virtual globe system. This is not a criticism of the science community, it is to be expected since norms take time to develop for any new technology. An example of the development of norms are pages on the web: when they first started appearing structure was unguided but over the last few years structural elements such as a left hand side navigation system and a bread crumb trail near the header have become common. In this paper I shall describe the developing norms of structure I have observed in one area of virtual globe development; Google Earth science outreach projects. These norms include text introductions, video introductions, use of folders and overlay presentation. I shall go on to examine how best to use these norms to build a clear and engaging outreach project and describe some cartographic best practices that we should also consider adopting as norms. I also will briefly explain why I think norms in science outreach aid creativity rather than limiting it despite the counter intuitive nature of this concept.

    This paper examines the Individualism–Collectivism (I-C) dimension of national culture in the Hofstede and GLOBE models. We identify major contradictions between the two culture models, which result in contradictory relationships with external variables such as economic prosperity. We critically evaluate the content validity of the items used to measure this construct in both models. Based on our analysis, we suggest that Hofstede's Individualism–Collectivism index be relabelled as Self-orien...

    The story about a properly oriented outdoor globe in the hands and minds of Eratosthenes, Jefferson, Milanković and science educators is presented. Having the same orientation in space as the Earth, the Day Night Year Globe (DING) shows in real time the pattern of illumination of the Earth’s surface and its diurnal and seasonal variations. It is an ideal object for the visualization of knowledge and increase in knowledge about: the form of the Earth, Earth’s rotation, Earth’s revolution around the Sun, the length of seasons, solstices, equinoxes, the longitude problem, the distribution of the Sun’s radiation over the Earth, the impact of this radiation on Earth’s climate, and how to use it efficiently. By attaching a movable vane to the poles, or adding pins around the equator to read time, DING becomes a spherical/globe-shaped sundial. So, the DING is simultaneously useful for teaching physics, geophysics, astronomy, use of solar energy and promoting an inquiry-based learning environment for students and the public. (paper)

    A 53 metre long and 6 metre high mural has graced the ramp of the Globe since 21 June. Containing life-size photos of the CMS experiment and an event in the ATLAS detector, its visual impact cannot fail to rouse visitors' curiosity.   The new mural installed in the Globe Visitors ascending from the ground-floor to the first floor of the Globe are now greeted by a huge visual record of what's going on below ground at CERN and is no longer accessible on guided tours of the Laboratory. "The mural contains full-scale photos that give you a real feel of how the CMS detector is constructed and of the degree of precision of the particle tracks in the ATLAS event", explains Rolf Landua, Head of the Education Group, who came up with the project in conjunction with Bernard Pellequer. Several people were instrumental in bringing the project to life. The collage of 250 photographs of the CMS detector was retouched and assembled by Maximilien Brice, CERN's photographer, with the assistance o...

  18. A key component of the Globe arrives

    2003-01-01

    The first component of the Palais de l'Equilibre arrived at CERN last week. Renamed the Globe of Innovation, this elegant wooden sphere will be inaugurated in October 2004. The convoy transporting the first component of the Palais de l'Equilibre, the keystone of the famous wooden globe, arrived at CERN on the night of 28th August in the middle of a violent storm and dramatic flashes of lightning. Erected in Neuchâtel last year for the EXPO.02 exhibition, the Palais de l'Equilibre was a gift to the Laboratory from the Swiss Confederation (see Bulletin 25/2003). The gift of the structure and 4 million Swiss francs, together with help from the Swiss army for the reassembly work, received the final approval of the Swiss Federal Council on 20th August 2003. Renamed the Globe of Innovation, the 27-metre-high sphere measuring 40 metres in diameter will house the Laboratory's new exhibition centre in 2005. The keystone, known as the "central vertex", is a crown measuring 6.5 m in diameter and 4.5 m high, located a...

    An innovative program to realize light pollution education on two continents via Internet 2-based videoconferencing was begun 4 years ago by the National Optical Astronomy Observatory. Bilingual science teachers and their students in Arizona and Chile recorded the brightness of the night sky by matching its appearance toward the constellation Orion with one of 6 stellar maps of limiting magnitude. Students from both hemispheres would report their findings via videoconferences. In the last year the program has evolved in collaboration with UCAR and other partners into an international, user-friendly, web-based science event open to anyone in the world, known as GLOBE at Night. GLOBE at Night uses the same design to observe and record the visible stars toward Orion, as a means of measuring light pollution in a given location. The inaugural event occurred over 11 nights last March, when 18,000 citizen- scientists made over 4,500 observations from 96 countries. Analysis of the GLOBE at Night data set found that the brighter skies corresponded to areas with higher population density, and that most observations were taken in a location with some light pollution. The data also tended to confirm that satellite data is reliable in assessing light pollution. This session will describe our program to incorporate more technology into the GLOBE at Night program. Citizen-scientists will use sky quality meters (visible light photometers), calibrated digital photography, and GPS as a means to measure and map more accurately the brightness of the sky at selected urban and rural sites. This extension of the program is designed to aid further in teaching about the impact of artificial lighting on local environments and the ongoing loss of a dark night sky as a natural resource. We will also describe how detailed maps of selected urban areas can be used to assess lighting design, safety considerations and energy usage. Given the widespread interest in the inaugural GLOBE at Night

  1. The new Globe car park: for visitors and the CERN community

    CERN Multimedia

    2014-01-01

    With twice as many parking spaces as the existing car park by the flagpoles and the same conditions of use (see here), the new Globe car park will be open for use from Monday 5 May.   The new Globe car park: the blue spaces are reserved for P+R pass holders. The new car park, which will be inaugurated on Monday 28 April by CERN’s Director-General in the presence of officials representing the Canton of Geneva and the sub-prefecture of the Ain, will better cater to the needs of CERN’s many visitors. The large number of spaces (around 100) reserved for P+R users will encourage the use of public transport, which will be particularly important at peak times. From autumn 2014, the Globe car park will completely replace the flagpole car park, where the new Esplanade des Particules will be built.

    Objective: To analyze potentials of frequency-doubling technology perimetry (FDP) for diagnosing open-angle glaucoma (OAG) in perimetrically normal eyes of OAG patients diagnosed with standard automated perimetry (SAP) and relating factors from abnormalities on FDP to visual field loss on SAP. Methods: A prospective cohort study. Sixty-eight eyes of 68 OAG patients visiting the ophthalmic clinic of Peking University Third Hospital during November 2003 and October 2007 [32 primary open-angle glaucoma patients and 36 normal tension glaucoma patients, 32 males and 36 females, with an average age of (59±13) years] with unilateral field loss detected by SAP (Octopus101 tG2 program) were examined with the FDP N-30 threshold program (Humphrey Instruments) at baseline. Two groups, FDP positive group and FDP negative group, were divided based on the FDP results, and visual field examinations were followed by a series of SAP examinations for the perimetrically normal eyes over 8 years. During the follow-up, the difference of the converting rate of SAP tests between the two groups was analyzed. Differences between "convertors" and "non-convertors" of SAP tests in the FDP positive group, such as the cup-to-disk ratio and glaucomatous optic neuropathy rate, were also compared with the independent-sample t test or Wilcoxon two-sample test for continuous variable data and the χ(2) test or Fisher exact test for classified variable data and rates. Results: Forty-eight perimetrically normal eyes of 48 participants had complete data and a qualifying follow-up. Baseline FDP results were positive in 33 eyes and negative in 15 eyes. Of the eyes with positive FDP results, 22 eyes developed abnormal SAP results after 4.0 to 90.0 months (median 14.5 months) , whereas none of the eyes with negative FDP results developed abnormal SAP results. For perimetrically normal eyes in the FDP positive group, "converters" showed a greater cup-to-disk ratio (0.73±0.09 vs . 0.63±0.14, Wilcoxon two

    Students, families, and educators worldwide participated in GLOBE at Night - an international event designed to observe and record the visible stars as a means of measuring light pollution in a given location. Participation was open to anyone - anywhere in the world - who could get outside and look skyward during the week of March 22-29, 2006. Our goal was 5000 observations from around the world in this prototype program.The hands-on learning activities associated with the program were designed to extend the traditional classroom and school day with a week of nighttime observations involving teachers, students and their families. By locating specific constellations in the sky, students from around the world learned how the lights in their community contribute to light pollution. Students explored the different light sources in their community learning the relationship between science, technology and society, and they reported their observations online through a central database allowing for authentic worldwide research and analysis. The observations made during GLOBE at Night helped students and scientists together assess how the quality of the night sky varies around the world as well as the level of energy wastage associated with poorly-shielded lights.For more information, visit http://www.globe.gov/globeatnight.GLOBE at Night is a collaboration between The GLOBE Program, the National Optical Astronomy Observatory (NOAO), Centro de Apoyo a la Didactica de la Astronomia (CADIAS) in Chile , Windows to the Universe, and Environmental Systems Research Institute, Inc.

    Educational policy bodies worldwide have argued that practicing inquiry as a part of the K-12 curriculum would help prepare students for their lives as adults in today's world. This study investigated adults who graduated high school 9 years earlier with a major in biology, to determine how they perceive the inquiry project they experienced and its contribution to their lives. We characterized dynamic inquiry performances and the retrospective perceptions of the inquiry project. Data was collected by interviews with 17 individuals—nine who engaged in open inquiry and eight who engaged in guided inquiry in high school. Both groups shared similar expressions of the affective point of view and procedural understanding criteria of dynamic inquiry, but the groups differed in the expression of the criteria changes occurring during inquiry and learning as a process. Participants from both groups described the contribution of the projects to their lives as adults, developing skills and positive attitudes towards science and remembering the content knowledge and activities in which they were involved. They also described the support they received from their teachers. Results of this study imply that inquiry, and particularly open inquiry, helps develop valuable skills and personal attributes, which may help the students in their lives as future adults. This retrospective point of view may contribute to a deeper understanding of the long-term influences of inquiry-based learning on students.

    Characterization of the biomechanical properties of the human eye has a number of potential utilities. One novel purpose is to provide the basis for development of suitable tissue-mimicking material. The purpose of this study was to determine the indentation and needle insertion characteristics on human eye globes and tissue strips. An indenter assessed the elastic response of human eye globes and tissue strips under increasing compressive loads. Needle insertion determined the force (N) needed to penetrate various areas of the eye wall. The results demonstrated that globes underwent slightly greater indentation at the midline than at the central cornea, and corneal strips indented twofold more than scleral strips, although neither difference was significant (P=0.400 and P=0.100, respectively). Significant differences were observed among various areas of needle insertion (Phuman eye construct with potential utility as a model for use in ophthalmology research and surgical teaching.

ASOCT scans with 3D mode angle analysis were taken with the CASIA SS-1000 (Tomey Corporation, Nagoya, Japan and analyzed using the Anterior Chamber Analysis and Interpretation software. Anterior iris surface length (AISL, length of scleral spur landmark (SSL to pupillary margin (SSL-to-PM, iris contour ratio (ICR = AISL/SSL-to-PM, pupil radius, radius of iris centroid (RICe, and iris volume were measured. Outcome variables were summarized for all eyes and age groups, and mean values among age groups were compared using one-way analysis of variance. Stepwise regression analysis was used to investigate demographic and ocular characteristic factors that affected each iris-related parameter.Mean (±SD values were 2.24 mm (±0.46, 4.06 mm (±0.27, 3.65 mm (±0.48, 4.16 mm (±0.47, 1.14 (±0.04, 1.51 mm2 (±0.23, and 38.42 μL (±4.91 for pupillary radius, RICe, SSL-to-PM, AISL, ICR, iris cross-sectional area, and iris volume, respectively. Both pupillary radius (P = 0.002 and RICe (P = 0.027 decreased with age, while SSL-to-PM (P = 0.002 and AISL increased with age (P = 0.001. ICR (P = 0.54 and iris volume (P = 0.49 were not affected by age.This study establishes reference values for iris-related parameters in an adult open angle population, which will be useful for future studies examining the role of iris changes in pathologic states.

    Full Text Available The trigeminal nerve carries the sensory innervation of the eye and adnexa in three divisions: ophthalmic, maxillary, and mandibular. The sensory fibres of the eye and adnexa are found in the ophthalmic division – with the exception of a portion of the sensory input from the lower lid, which is carried by the maxillary division. Blocking the sensory fibres provides anaesthesia so that no pain is felt.The motor supply of the extraocular muscles and levator palpebrae superioris is carried by the oculomotor (III, trochlear (IV, and abducens (VI nerves. Paralysing these muscles by blocking their motor supply provides akinesia so that the eye does not move during surgery.The motor supply of the orbicularis oculi, which is responsible for the gentle and forcible closure of the eye, is carried by the facial nerve (VII. Blocking these fibres will provide better surgical exposure. It also reduces the risk of forcing out the ocular contents if the patient tries to close his eyelids forcibly after the surgeon opens the globe.

  10. Assessing the accuracy of globe thermometer method in predicting outdoor mean radiant temperature under Malaysia tropical microclimate

    Assessing outdoor human thermal comfort and urban climate quality require experimental investigation of microclimatic conditions and their variations in open urban spaces. For this, it is essential to provide quantitative information on air temperature, humidity, wind velocity and mean radiant temperature. These parameters can be quantified directly except mean radiant temperature (Tmrt). The most accurate method to quantify Tmrt is integral radiation measurements (3-D shortwave and long-wave) which require using expensive radiometer instruments. To overcome this limitation the well-known globe thermometer method was suggested to calculate Tmrt. The aim of this study was to assess the possibility of using indoor globe thermometer method in predicting outdoor mean radiant temperature under Malaysia tropical microclimate. Globe thermometer method using small and large sizes of black-painted copper globes (50mm, 150mm) were used to estimate Tmrt and compare it with the reference Tmrt estimated by integral radiation method. The results revealed that the globe thermometer method considerably overestimated Tmrt during the middle of the day and slightly underestimated it in the morning and late evening. The difference between the two methods was obvious when the amount of incoming solar radiation was high. The results also showed that the effect of globe size on the estimated Tmrt is mostly small. Though, the estimated Tmrt by the small globe showed a relatively large amount of scattering caused by rapid changes in radiation and wind speed.

    Purpose: To compare the diagnostic performance of the Heidelberg retinal tomograph (HRT) glaucoma probability score (GPS) with that of Moorfield’s regression analysis (MRA). Materials and Methods: The study included 50 eyes of normal subjects and 50 eyes of subjects with early-to-moderate primary open angle glaucoma. Images were obtained by using HRT version 3.0. Results: The agreement coefficient (weighted k) for the overall MRA and GPS classification was 0.216 (95% CI: 0.119 – 0.315). The sensitivity and specificity were evaluated using the most specific (borderline results included as test negatives) and least specific criteria (borderline results included as test positives). The MRA sensitivity and specificity were 30.61 and 98% (most specific) and 57.14 and 98% (least specific). The GPS sensitivity and specificity were 81.63 and 73.47% (most specific) and 95.92 and 34.69% (least specific). The MRA gave a higher positive likelihood ratio (28.57 vs. 3.08) and the GPS gave a higher negative likelihood ratio (0.25 vs. 0.44).The sensitivity increased with increasing disc size for both MRA and GPS. Conclusions: There was a poor agreement between the overall MRA and GPS classifications. GPS tended to have higher sensitivities, lower specificities, and lower likelihood ratios than the MRA. The disc size should be taken into consideration when interpreting the results of HRT, as both the GPS and MRA showed decreased sensitivity for smaller discs and the GPS showed decreased specificity for larger discs.

    Dry eye disease (DED), a chronic disorder affecting the tear film and lacrimal functional unit, is a widely prevalent condition associated with significant burden and unmet treatment needs. Since specific neural circuits play an important role in maintaining ocular surface health, microelectrical stimulation of these pathways could present a promising new approach to treating DED. This study evaluated the efficacy and safety of nasal electrical stimulation in patients with DED. This prospective, open-label, single-arm, nonrandomized pilot study included 40 patients with mild to severe DED. After undergoing two screening visits, enrolled subjects were provided with a nasal stimulation device and instructed to use it at home four times daily (or more often as needed). Follow-up assessments were conducted up to day 180. The primary efficacy endpoint was the difference between unstimulated and stimulated tear production quantified by Schirmer scores. Additional efficacy endpoints included change from baseline in corneal and conjunctival staining, symptoms evaluated on a Visual Analog Scale, and Ocular Surface Disease Index scores. Safety parameters included adverse event (AE) rates, visual acuity, intraocular pressure, slit-lamp biomicroscopy, indirect ophthalmoscopy, and endoscopic nasal examinations. Mean stimulated Schirmer scores were significantly higher than the unstimulated scores at all visits, and corneal and conjunctival staining and symptom scores from baseline to day 180 were significantly reduced. No serious device-related AEs and nine nonserious AEs (three device-related) were reported. Intraocular pressure remained stable and most subjects showed little or no change in visual acuity at days 30 and 180. No significant findings from other clinical examinations were noted. Neurostimulation of the nasolacrimal pathway is a safe and effective means of increasing tear production and reducing symptoms of dry eye in patients with DED.

    Occupational injury represents 7,7 at 69,9% of the total ocular traumatisms. They can be a major source of visuel loss and blindness. The aim is to study the epidemiology of work-related ocular injuries: objects frequencies,works most exposed. We performed a prospective study that interest 78 patients having a work-related ocular traumatism during a 4 months period. They were admitted at ocular emergeney All patients underwent an ophtalmologic examination completed with orbital radiography and echography. A medical and/or chirurgical appropriate treatment was institued. Occupationnal injury frequency was 9% of the whole ocular traumatisms in the same period. The mean age was 31 years. 55% of cases were under 30 years. 91% were male. Most exposed works were industrial and mecanical sectors In 70,5% of cases work-related eye injuries were caused by projectile objects. Most common lesion was corneal superficial foreign body (58%). Open globe injury was noted in 8%. 95% of patients had no eye protection at the time of the accident. 13% were blind or unilateral partially sighted (according to the OMS classification). The authors discussed the importance and different prevention strategies to prevent the risk of blindness and socio-economical cost of occupationnal accidents. There is a need for systematic periodic sensibilization to reduce these accidents and blindness.

  16. A Software Prototype For Accessing Large Climate Simulation Data Through Digital Globe Interface

    The IPCC suite of global Earth system models produced terabytes of data for the CMIP3/AR4 archive and is expected to reach the petabyte scale by CMIP5/AR5. Dynamic downscaling of global models based on regional climate models can potentially lead to even larger data volumes. The model simulations for global or regional climate models like CCSM3 or WRF are typically run on supercomputers like the ORNL/DOE Jaguar and the results are stored on high performance storage systems. Access to these results from a user workstation is impeded by a number of factors such as enormous data size, limited bandwidth of standard office networks, data formats which are not fully supported by applications. So, a user-friendly interface for accessing and visualizing these results over standard Internet connection is required to facilitate collaborative work among geographically dispersed groups of scientists. To address this problem, we have developed a virtual globe based application which enables the scientists to query, visualize and analyze the results without the need of large data transfers to desktops and department-level servers. We have used open-source NASA WorldWind as a virtual globe platform and extended it with modules capable of visualizing model outputs stored in NetCDF format, while the data resides on the high-performance system. Based on the query placed by the scientist, our system initiates data processing routines on the high performance storage system to subset the data and reduce its size and then transfer it back to scientist's workstation through secure shell tunnel. The whole operation is kept totally transparent to the scientist and for the most part is controlled from a point-and-click GUI. The virtual globe also serves as a common platform for geospatial data, allowing smooth integration of the model simulation results with geographic data from other sources such as various web services or user-specific data in local files, if required. Also the system has

    Full Text Available A two-year experiment was carried-out in order to evaluate the effects of two plant arrangements (single vs. twin rows and four plant densities (1.0 -1.2 -1.4 and 1.8 plant m–2 on the agronomical behaviour and head characteristics of three globe artichoke genotypes (Violetto di Sicilia, Harmony F1 and Madrigal F1. The change of the cultivation format toward a high density stand significantly increase yield and yield synchronicity. The twin rows plant arrangement, although reduced total yield, increased the yield synchronicity. Moreover, the cultivation of seed-propagated genotypes (Harmony F1 and Madrigal F1 allowed extending significantly the availability of the heads across the year. On the basis of our results, we can assert that the implementation of a specific scheduling cultivation, based on higher density stands, twin rows plant arrangement and the integration of the traditional early genotypes with the new seed-propagated cultivars, is a promising way to match the requirements of a globe artichoke industrial crop, and to predispose a better mechanization of the cultural practices.

  18. Globe hosts launch of new processor

    2006-01-01

    Launch of the quadecore processor chip at the Globe. On 14 November, in a series of major media events around the world, the chip-maker Intel launched its new 'quadcore' processor. For the regions of Europe, the Middle East and Africa, the day-long launch event took place in CERN's Globe of Science and Innovation, with over 30 journalists in attendance, coming from as far away as Johannesburg and Dubai. CERN was a significant choice for the event: the first tests of this new generation of processor in Europe had been made at CERN over the preceding months, as part of CERN openlab, a research partnership with leading IT companies such as Intel, HP and Oracle. The event also provided the opportunity for the journalists to visit ATLAS and the CERN Computer Centre. The strategy of putting multiple processor cores on the same chip, which has been pursued by Intel and other chip-makers in the last few years, represents an important departure from the more traditional improvements in the sheer speed of such chips. ...

    Twenty years ago, the Internet was still in its infancy, citizen science was a relatively unknown term, and the idea of a global citizen science database was unheard of. Then the Global Learning and Observations to Benefit the Environment (GLOBE) Program was proposed and this all changed. GLOBE was one of the first K-12 citizen science programs on a global scale. An initial large scale ramp-up of the program was followed by the establishment of a network of partners in countries and within the U.S. Now in the 21st century, the program has over 50 protocols in atmosphere, biosphere, hydrosphere and pedosphere, almost 140 million measurements in the database, a visualization system, collaborations with NASA satellite mission scientists (GPM, SMAP) and other scientists, as well as research projects by GLOBE students. As technology changed over the past two decades, it was integrated into the program's outreach efforts to existing and new members with the result that the program now has a strong social media presence. In 2016, a new app was launched which opened up GLOBE and data entry to citizen scientists of all ages. The app is aimed at fresh audiences, beyond the traditional GLOBE K-12 community. Groups targeted included: scouting organizations, museums, 4H, science learning centers, retirement communities, etc. to broaden participation in the program and increase the number of data available to students and scientists. Through the 20 years of GLOBE, lessons have been learned about changing the management of this type of large-scale program, the use of technology to enhance and improve the experience for members, and increasing community involvement in the program.

  2. Come and see: Opening eyes, minds and dialogue. Taking stock in the fourth year of Swiss NPP advertising

    International Nuclear Information System (INIS)

    Hahlen, Peter

    1999-01-01

    It is now clear that the 'come and see' concept underlying the Swiss NPPs TV advertising campaign, which started in 1995/96, really does work - even over a period of several years. This is not a trivial finding: other, recent, TV and print ad campaigns with more far-reaching nuclear messages (relating to waste management issues) provoked noisy and hostile political reactions. The concept of an extensively regionalised testimonial print ad campaign running 'under the roof' of the national TV campaign works very well. However, it must be stressed that detailed knowledge of social, political and media related situations in the regions addressed is of paramount importance, and approaches have to be carefully adapted to these geographically widely varying conditions. The invitation to dialogue, with its natural openness, is well received by the public and by opinion leaders, in particular by journalists - something which is observed every time the campaign starts in a new region. The aim of the programme, namely to give the Swiss NPPs 'a voice of their own', has been attained, despite a rather moderate budget. The fact that the Swiss NPPs speak out on their own, without reference to their superiors in the economic hierarchy is accepted and even well received by both the media and the public. The principle of devoting at least half the budget to the direct costs of 'placing' TV ads - in order to attain recognition in the face of the prevailing flood of information - has been proved to be the right one. Professional advertising efficiency controls carried out every year since the start of the campaign have confirmed that the NNP TV ads have been 'noticed' by a reasonably high percentage of the public, compared to other TV ads shown at the same time. The budget of 2 million Swiss francs (roughly US$ 27 million) per year, corresponding to almost 1 US dollar per private household or less than half a dollar per capita of the Swiss population, was very tight. The aim of the

    Multiphase flows are frequently encountered in metallurgical operations. One of the most effective ways to understand these processes is by flow modeling. The process of tundish open eye (TOE) formation involves three-phase interaction between liquid steel, slag, and argon gas. The two-phase interaction involving argon gas bubbles and liquid steel can be modeled relatively easily using the discrete phase modeling technique. However, the effect of an upper slag layer cannot be captured using this approach. The presence of an upper buoyant phase can have a major effect on the behavior of TOEs. Hence, a multiphase model, including three phases, viz. liquid steel, slag, and argon gas, in a two-strand slab caster tundish, was developed to study the formation and evolution of TOEs. The volume of fluid model was used to track the interphase between liquid steel and slag phases, while the discrete phase model was used to trace the movement of the argon gas bubbles in liquid steel. The variation in the TOE areas with different amounts of aspirated argon gas was examined in the presence of an overlying slag phase. The mathematical model predictions were compared against steel plant measurements.

    Students from the University of Bonn put on three highly successful performances of their "Physikshow", a theatrical journey into the world of particles.   All you need is a bit of imagination and stage management for even the most abstract of physics to become entertaining and intelligible, a principle demonstrated by 20 students from the University of Bonn and their teachers who gave three performances of their "Physikshow" in the Globe of Science and Innovation. The students quickly won over their audience using an array of amazing experiments and wacky sketches to illustrate the world of particles, the principle of forces and the evolution of the cosmos. More than 370 pupils from local secondary schools in France and the Cantons of Geneva and Vaud travelled to CERN for the two performances specially reserved for schools. The audience for the public performance numbered no fewer than 250. Physikshow was first performed in 2002 and has evolved over the years th...

    Full Text Available BACKGROUND Eye injuries still remain one of the most common causes of unilateral blindness worldwide. In addition to the physical and psychological trauma to the patient, the direct and indirect costs to the society are enormous. Blunt eye injuries commonly result in traumatic hyphaema and are not an infrequent cause of presentation to the emergency units of many eye clinics. Aims of this study were- 1. To study the cause, clinical presentation, complications and visual outcome of closed globe injury with hyphaema. 2. To know the association between mode of injuries and associated lesions and visual outcome. MATERIALS AND METHODS Study Design and Statistical Analysis- A descriptive case series study was conducted at Regional Institute of Ophthalmology, Thiruvananthapuram for a period of one year, from October 2010 to September 2011, in all patients coming to the institute with hyphaema due to closed globe injury and willing to participate in the study. Patients with pre-existing ocular diseases were excluded. Data were analysed using computer software, Statistical Package for Social Sciences (SPSS version 10. Data are expressed in its frequency and percentage. To elucidate the associations and comparisons between different parameters, Chi square ( 2 test was used as a nonparametric test. For all statistical evaluations, a two-tailed probability of value, 6/60 either maintained that vision or improved. Only 10% of the study population had corneal blood staining. Majority of those who had initial hyphaema <1/3 rd , had normal initial intraocular pressure. Of the total 36 patients who had initial hyphaema less than 1/3 rd , 29 (80.6% had normal intraocular pressure on presentation. Of the 36 patients with initial hyphaema <1/3 rd , 28 (77.8% had normal intraocular pressure at 3 rd day. Those who had lenticular and posterior segment injury had poor visual outcome. In our study, initially only 15% had vision better than 6/12, but at the end of 180

    Full Text Available Abstract Background The prerequisites for a good capsulorhexis include a deep, well maintained anterior chamber, globe stabilization and globe manipulation. This helps to achieve a capsulorhexis of optimal size, shape and obtain the best possible position for a red glow under retroillumination. We report the use of irrigation handpiece of bimanual irrigation aspiration system to stabilize the globe, maintain a deep anterior chamber and manipulate the globe to a position of optimal red reflex during needle capsulorhexis in phacoemulsification. Methods Two side ports are made with 20 G MVR 'V' lance knife (Alcon, USA. The irrigation handpiece with irrigation on is introduced into the anterior chamber through one side port and the 26-G cystitome (made from 26-G needle is introduced through the other. The capsolurhexis is completed with the needle. Results Needle capsulorhexis with this technique was used in 30 cases of uncomplicated immature senile cataracts. 10 cases were done under peribulbar anaesthesia and 20 under topical anaesthesia. A complete capsulorhexis was achieved in all cases. Conclusion The irrigating handpiece maintains deep anterior chamber, stabilizes the globe, facilitates pupillary dilatation, and helps in maintaining the eye in the position with optimal red reflex during needle capsulorhexis. This technique is a safe and effective way to perform needle capsulorhexis.

Since specific neural circuits play an important role in maintaining ocular surface health, microelectrical stimulation of these pathways could present a promising new approach to treating DED. This study evaluated the efficacy and safety of nasal electrical stimulation in patients with DED. Methods: This prospective, open-label, single-arm, nonrandomized pilot study included 40 patients with mild to severe DED. After undergoing two screening visits, enrolled subjects were provided with a nasal stimulation device and instructed to use it at home four times daily (or more often as needed. Follow-up assessments were conducted up to day 180. The primary efficacy endpoint was the difference between unstimulated and stimulated tear production quantified by Schirmer scores. Additional efficacy endpoints included change from baseline in corneal and conjunctival staining, symptoms evaluated on a Visual Analog Scale, and Ocular Surface Disease Index scores. Safety parameters included adverse event (AE rates, visual acuity, intraocular pressure, slit-lamp biomicroscopy, indirect ophthalmoscopy, and endoscopic nasal examinations. Results: Mean stimulated Schirmer scores were significantly higher than the unstimulated scores at all visits, and corneal and conjunctival staining and symptom scores from baseline to day 180 were significantly reduced.

    The visualization of scientific datasets is becoming an ever-increasing challenge as advances in computing technologies have enabled scientists to build high resolution climate models that have produced petabytes of climate data. To interrogate and analyze these large datasets in real-time is a task that pushes the boundaries of computing hardware and software. But integration of climate datasets with geospatial data requires considerable amount of effort and close familiarity of various data formats and projection systems, which has prevented widespread utilization outside of climate community. TrikeND-iGlobe is a sophisticated software tool that bridges this gap, allows easy integration of climate datasets with geospatial datasets and provides sophisticated visualization and analysis capabilities. The objective for TrikeND-iGlobe is the continued building of an open source 4D virtual globe application using NASA World Wind technology that integrates analysis of climate model outputs with remote sensing observations as well as demographic and environmental data sets. This will facilitate a better understanding of global and regional phenomenon, and the impact analysis of climate extreme events. The critical aim is real-time interactive interrogation. At the data centric level the primary aim is to enable the user to interact with the data in real-time for the purpose of analysis - locally or remotely. TrikeND-iGlobe provides the basis for the incorporation of modular tools that provide extended interactions with the data, including sub-setting, aggregation, re-shaping, time series analysis methods and animation to produce publication-quality imagery. TrikeND-iGlobe may be run locally or can be accessed via a web interface supported by high-performance visualization compute nodes placed close to the data. It supports visualizing heterogeneous data formats: traditional geospatial datasets along with scientific data sets with geographic coordinates (NetCDF, HDF, etc

    2013-10-01

    Inspired by the visionary idea of Digital Earth, as well as from the tremendous improvements in geo-technologies, use of virtual globes has been changing the way people approach to geographic information on the Web. Unlike the traditional 2D-visualization typical of Geographic Information Systems (GIS), virtual globes offer multi-dimensional, fully-realistic content visualization which allows for a much richer user experience. This research investigates the potential for using virtual globes to foster tourism and enhance cultural heritage. The paper first outlines the state of the art for existing virtual globes, pointing out some possible categorizations according to license type, platform-dependence, application type, default layers, functionalities and freedom of customization. Based on this analysis, the NASA World Wind virtual globe is the preferred tool for promoting tourism and cultural heritage. This is because its open source nature allows unlimited customization (in terms of both data and functionalities), and its Java core supports platform-independence. Relevant tourism-oriented World Wind-based applications, dealing with both the Web promotion of historical cartography and the setup of a participatory Web platform exploiting crowd-sourced data, are described. Finally, the paper presents a project focusing on the promotion of the Via Regina area (crossing the border between Italy and Switzerland) through an ad hoc World Wind customization. World Wind can thus be considered an ideal virtual globe for tourism applications, as it can be shaped to increase awareness of cultural history and, in turn, enhance touristic experience.

  11. Web GIS in practice VII: stereoscopic 3-D solutions for online maps and virtual globes

    2009-01-01

    Because our pupils are about 6.5 cm apart, each eye views a scene from a different angle and sends a unique image to the visual cortex, which then merges the images from both eyes into a single picture. The slight difference between the right and left images allows the brain to properly perceive the 'third dimension' or depth in a scene (stereopsis). However, when a person views a conventional 2-D (two-dimensional) image representation of a 3-D (three-dimensional) scene on a conventional computer screen, each eye receives essentially the same information. Depth in such cases can only be approximately inferred from visual clues in the image, such as perspective, as only one image is offered to both eyes. The goal of stereoscopic 3-D displays is to project a slightly different image into each eye to achieve a much truer and realistic perception of depth, of different scene planes, and of object relief. This paper presents a brief review of a number of stereoscopic 3-D hardware and software solutions for creating and displaying online maps and virtual globes (such as Google Earth) in "true 3D", with costs ranging from almost free to multi-thousand pounds sterling. A practical account is also given of the experience of the USGS BRD UMESC (United States Geological Survey's Biological Resources Division, Upper Midwest Environmental Sciences Center) in setting up a low-cost, full-colour stereoscopic 3-D system.

    Full Text Available AIM: To conduct a systematic review and quantitative Meta-analysis of the efficacy and safety of combined surgery for the eyes with coexisting cataract and open angle glaucoma. METHODS: We performed a systematic search of the related literature in the Cochrane Library, PubMed, EMBASE, Web of Science databases, CNKI, CBM and Wan Fang databases, with no limitations on language or publication date. The primary efficacy estimate was identified by weighted mean difference of the percentage of intraocular pressure reduction (IOPR% from baseline to end-point, the percentage of number of glaucoma medications reduction from pre- to post-operation, and the secondary efficacy evaluations were performed by odds ratio (OR and 95% confidence interval (CI for complete and qualified success rate. Besides, ORs were applied to assess the tolerability of adverse incidents. Meta-analyses of fixed or random effect models were performed using RevMan software 5.2 to gather the consequences. Heterogeneity was evaluated by Chi2 test and the I2 measure. RESULTS: Ten studies enrolling 3108 patients were included. The combined consequences indicated that both glaucoma and combined cataract and glaucoma surgery significantly decreased IOP. For deep sclerectomy vs deep sclerectomy plus phacoemulsification and canaloplasty vs phaco-canaloplasty, the differences in IOPR% were not all statistically significant while trabeculotomy was detected to gain a quantitatively greater IOPR% compared with trabeculotomy plus phacoemulsification. Furthermore, there was no statistical significance in the complete and qualified success rate, and the rates of adverse incidents for trabeculotomy vs trabeculotomy plus phacoemulsification. CONCLUSION: Compared with trabeculotomy plus phacoemulsification, trabeculectomy alone is more effective in lowering IOP and the number of glaucoma medications, while the two surgeries can not demonstrate statistical differences in the complete success rate

    Buzz Aldrin! The news caused a sensation: his arrival was imminent. The man who, 40 years ago, first step foot on the moon, was to do the same at CERN.   Buzz Aldrin dumps the pilot beams from the LHC. Visiting the Globe on 1 March to endorse General Motors’ (GM) new ecological programme, Buzz Aldrin took advantage of the occasion to take a whistle-stop tour of the Organisation. “CERN is dealing with things going very fast underground; I’m dealing with things going fast – not that fast though! – up in orbit,” he said. Accompanied by his wife Lois and singer Katie Melua - also invited by GM to perform at the private event - Buzz began his visit with a short introduction to CERN at the Universe of Particles exhibit. He then met with Andrzej Siemko, group leader of the LHC machine protection, at the SM-18 super conducting magnet test facility. The astronaut’s last stop was at the CCC, where the LHC team had somethi...

  19. Virtual Globes: Serving Science and Society

    Directory of Open Access Journals (Sweden)

    2012-08-01

    Full Text Available Virtual Globes reached the mass market in 2005. They created multi-million dollar businesses in a very short time by providing novel ways to explore data geographically. We use the term “Virtual Globes” as the common denominator for technologies offering capabilities to annotate, edit and publish geographic information to a world-wide audience and to visualize information provided by the public and private sectors, as well as by citizens who volunteer new data. Unfortunately, but not surprising for a new trend or paradigm, overlapping terms such as “Virtual Globes”, “Digital Earth”, “Geospatial Web”, “Geoportal” or software specific terms are used heterogeneously. We analyze the terminologies and trends in scientific publications and ask whether these developments serve science and society. While usage can be answered quantitatively, the authors reason from the literature studied that these developments serve to educate the masses and may help to democratize geographic information by extending the producer base. We believe that we can contribute to a better distinction between software centered terms and the generic concept as such. The power of the visual, coupled with the potential of spatial analysis and modeling for public and private purposes raises new issues of reliability, standards, privacy and best practice. This is increasingly addressed in scientific literature but the required body of knowledge is still in its infancy.

    Eye injuries frequently occur in the home, at work and at play. Many result in legally blind eyes, and most are preventable. Awareness of potential hazards is essential to preventing eye injuries, particularly in children. In addition, protective devices must be used appropriately. We have developed eye protectors that have proved effective in reducing both the overall incidence and the severity of sports eye injuries.

    Shiu, Almon S.; Tung, Samuel S.; Gastorf, Robert J.; Hogstrom, Kenneth R.; Morrison, William H.; Peters, Lester J.

    1996-01-01

    Purpose: The purpose of this study is to report that commercially available eye shields (designed for orthovoltage x-rays) are inadequate to protect the ocular structures from penetrating electrons for electron beam energies equal to or greater than 6 MeV. Therefore, a prototype medium size tungsten eye shield was designed and fabricated. The advantages of the tungsten eye shield over lead are discussed. Methods and Materials: Electron beams (6-9 MeV) are often used to irradiate eyelid tumors to curative doses. Eye shields can be placed under the eyelids to protect the globe. Film and thermoluminescent dosimeters (TLDs) were used within a specially constructed polystyrene eye phantom to determine the effectiveness of various commercially available internal eye shields (designed for orthovoltage x-rays). The same procedures were used to evaluate a prototype medium size tungsten eye shield (2.8 mm thick), which was designed and fabricated for protection of the globe from penetrating electrons for electron beam energy equal to 9 MeV. A mini-TLD was used to measure the dose enhancement due to electrons backscattered off the tungsten eye shield, both with or without a dental acrylic coating that is required to reduce discomfort, permit sterilization of the shield, and reduce the dose contribution from backscattered electrons. Results: Transmission of a 6 MeV electron beam through a 1.7 mm thick lead eye shield was found to be 50% on the surface (cornea) of the phantom and 27% at a depth of 6 mm (lens). The thickness of lead required to stop 6-9 MeV electron beams is impractical. In place of lead, a prototype medium size tungsten eye shield was made. For 6 to 9 MeV electrons, the doses measured on the surface (cornea) and at 6 mm (lens) and 21 mm (retina) depths were all less than 5% of the maximum dose of the open field (4 x 4 cm). Electrons backscattered off a tungsten eye shield without acrylic coating increased the lid dose from 85 to 123% at 6 MeV and 87 to 119% at

  12. Ocular health among radiologists in the age of PACS: is it time for our profession to open its eyes to this issue in light of existing European legislation?

    LENUS (Irish Health Repository)

    Halpenny, D

    2012-12-01

    The regular use of visual display units (VDUs) at work has been shown to cause the development of a constellation of symptoms ranging from dry eyes to temporary myopia. European workers who use VDUs are now protected under detailed legislation enacted by the European Union (Directive 90\\/270\\/EEC). The use of picture archiving and communications systems, which are almost ubiquitous in European countries, means that, as a profession, radiologists fall under the remit of this legislation. This paper aims to assess the impact that full implementation of this law would have on a radiologist\\'s practice and to more broadly examine the issue of eye care as an occupational health issue in radiology. The authors conclude that eye care in the setting of regular VDU use among radiologists is an important quality control and occupational health issue. There is a clear legal basis requiring employers to provide regular eye examinations and reporting breaks. In the absence of leadership from employers on this issue individual radiologists have a responsibility to ensure that their work practices reflect the legal situation and minimise the effect of eye strain on their performance.

    2010-07-01

    The objective of this study was to evaluate risk factors associated with eyeball loss and ambulatory vision loss on emergent examination of patients with ocular trauma. We reviewed the medical records of 1,875 patients hospitalized in a single tertiary referral center between January 2003 and December 2007. Emergent examinations included a history of trauma, elapsed time between injury and hospital arrival, visible intraocular tissues, and initial visual acuity (VA) using a penlight. The main outcome measures were ocular survival and ambulatory vision survival (>20/200) at 1 year after trauma using univariate and multivariate regression analysis. The ocular trauma scores were significantly higher in open globe injuries than in closed globe injuries (p eyeball loss. Elapsed time more than 12 hours and visible intraocular tissues were the significant risk factors associated with ambulatory vision loss. The most powerful predictor of eyeball loss and ambulatory vision loss was eyeball rupture. In closed globe injuries, there were no significant risk factors of eyeball loss, whereas initial vision less than LP and the presence of relative afferent pupillary defect were the significant risk factors associated with ambulatory vision loss. An initial VA less than LP using a penlight, a history of golf ball injury, and elapsed time more than 12 hours between ocular trauma and hospital arrival were associated with eyeball loss and ambulatory vision loss. Physicians should bear these factors in mind so that they can more effectively counsel patients with such injuries.

    One objective of the "Ocean Autonomous Observation" team of the Laboratory of Oceanography of Villefranche-sur-mer is to develop new means to outreach our science activities to various audiences. Besides the scientific community, this includes students and targets the general public, school pupils, and stakeholders. In this context, we have acquired a digital video globe with tactile capabilities and we will present here the various applications that we have been developing. A first type of products concerns the visualization of oceanic properties (SST, salinity, density, Chla, O2, NO3, irradiance) by diving from the surface (generally from satellite data) into the Ocean interior (through the use of global data bases, Argo, WOA). In second place, specific applications deal with surface animations allowing highlighting the seasonality of some properties (Chla, SST, ice cover, currents; based on satellite as well as modeling outputs). Finally, we show a variety of applications developed using the tactile functionality of the spherical display. In particular real-time vertical profiles acquired by Bio-Argo floats become directly accessible for the entire open ocean. Such a new tool plus its novel applications has been presented to school children, and to the wider public (at the so-called "fête de la science") as well as to potential sponsors of our science-outreach activities. Their feedback has always been highly positive and encouraging in terms of impact. From the scientists point of view, the use of this new support can easily compete with the classical PowerPoint, is much more attractive and fun and undeniably helps to outreach the various aspects of our pluridisciplinary science.

  18. How Cool was the Eclipse? Atmospheric Measurements and Citizen Science via NASA's GLOBE Observer

    The solar eclipse of 2017 presented an extraordinary opportunity to engage the public in shared science activity across the entire United States. While a natural focus of the eclipse was on astronomy and heliophysics, there was also an opening for excellent connections to Earth science. Because of the excitement of the event, many people gathered for long periods before and after totality, a perfect opportunity for observations and data collection to explore the impact of the eclipse on the atmosphere. The data was collected via NASA's GLOBE Observer app, a subset of the Global Learning and Observations to Benefit the Environment Program, a citizen science project which has been active for more than 20 years training teachers to collect many different types of environmental science data with their students. GLOBE Observer expands that audience to citizen scientists who might not be connected to a school, but are still interested in collecting data. In addition to the clouds observations that are normally part of GLOBE Observer, a special temporary protocol was added for the eclipse to include air temperature. Both types of measurements were collected at regular intervals for several hours before and after the point of maximum eclipse. By crowdsourcing data from all across the United States, on and off the path of totality, the hope was to be able to see patterns that wouldn't be apparent with fewer data points. In particular, there are few sources of detailed cloud data from the ground, including cloud type as well as overall cloud cover, especially as collected during a unique natural experiment such as an eclipse. This presentation will report preliminary results of the GLOBE Observer eclipse citizen science project, including participation totals and impact, data site distribution, as well as early analyses of both temperature and cloud data.

    To present a novel method for accurately characterizing the position of the globe relative to the orbital rim. The appearance and function of the eyelids are dependent on the underlying orbital bony architecture and globe position; however, no comprehensive language to describe these complex 3-dimensional relationships exists. Three-dimensional orbital reconstructions were generated from computed tomographic scans of 15 Occidental and 12 Oriental orbits without orbital pathologic disease. Globe and orbital rim anatomy were identified and outlined. Reference points were measured along 2 independent axes: (1) the distance between a plane defined by the corneal apex and the sagittal projection of the orbital rim and (2) the distance between the circumference of the globe and the coronal projection of the orbital rim. For Occidental orbits, the mean (SD) elevation of the sagittal projection of the orbital rim relative to the anterior projection of the globe was 4.6 (4.2) mm superiorly, 5.9 (3.0) mm nasally, 12.6 (3.7) mm inferiorly, and 20.6 (2.6) mm laterally. The mean (SD) radial distance between the coronal projection of the orbital rim and the circumference of the globe was 3.7 (2.1) mm superiorly, 7.6 (1.8) mm nasally, 6.6 (2.2) mm inferiorly, and 4.6 (2.3) mm laterally. For Oriental orbits, the mean (SD) elevation of the sagittal projection of the orbital rim relative to the anterior projection of the globe was 5.0 (4.5) mm superiorly, 6.8 (4.1) mm nasally, 11.1 (4.3) mm inferiorly, and 17.5 (3.3) mm laterally. The mean (SD) radial distance between the coronal projection of the orbital rim and the circumference of the globe was 2.1 (1.2) mm superiorly, 8.2 (2.0) mm nasally, 6.5 (1.9) mm inferiorly, and 4.5 (1.7) mm laterally. Comparison of Occidental and Oriental orbital rim and globe configurations revealed quantitative and qualitative differences. In addition to differences in soft-tissue anatomy, bony architectural variations may contribute substantially to

    During the spring of 2016, from April 4 - May 27, sixteen GLOBE schools participated in the GLOBE Aerosol Field Campaign - U.S. Pilot Study. Thirteen teachers from these schools had previously participated in the NASA LEARN program (Long-term Experience in Authentic Research with NASA) where they were GLOBE trained in Atmosphere protocols, and engaged in 1-3 years of research under the mentorship of NASA scientists. Each school was loaned two aerosol instruments for the Campaign duration, either 2 GLOBE sun photometers, 2 Calitoo sun photometers, or 1 of each. This allowed for students to make measurements side-by-side and in the case of the Calitoos, to compare AOT results immediately with each other for better consistency in data collection. Additionally, as part of the Field Campaign evaluation, multiple instruments allow for an assessment of the ease of use of each instrument for grade level of students, whether in middle school or high school. Before the Campaign, all GLOBE and Calitoo instruments were 'checked out' against an AERONET, then checked again upon return after the Campaign. By examining all data, before, during and after the Campaign, this gives an indication of instrument performance and proficiency obtained by the students. Support was provided to each teacher and their students at the level requested, via email, phone or video conferencing.

  3. Visualizing dynamic geosciences phenomena using an octree-based view-dependent LOD strategy within virtual globes

    2011-09-01

    Geoscientists build dynamic models to simulate various natural phenomena for a better understanding of our planet. Interactive visualizations of these geoscience models and their outputs through virtual globes on the Internet can help the public understand the dynamic phenomena related to the Earth more intuitively. However, challenges arise when the volume of four-dimensional data (4D), 3D in space plus time, is huge for rendering. Datasets loaded from geographically distributed data servers require synchronization between ingesting and rendering data. Also the visualization capability of display clients varies significantly in such an online visualization environment; some may not have high-end graphic cards. To enhance the efficiency of visualizing dynamic volumetric data in virtual globes, this paper proposes a systematic framework, in which an octree-based multiresolution data structure is implemented to organize time series 3D geospatial data to be used in virtual globe environments. This framework includes a view-dependent continuous level of detail (LOD) strategy formulated as a synchronized part of the virtual globe rendering process. Through the octree-based data retrieval process, the LOD strategy enables the rendering of the 4D simulation at a consistent and acceptable frame rate. To demonstrate the capabilities of this framework, data of a simulated dust storm event are rendered in World Wind, an open source virtual globe. The rendering performances with and without the octree-based LOD strategy are compared. The experimental results show that using the proposed data structure and processing strategy significantly enhances the visualization performance when rendering dynamic geospatial phenomena in virtual globes.

  6. Improving predictive capabilities of environmental change with GLOBE data

    Science.gov (United States)

    Robin, Jessica Hill

    This dissertation addresses two applications of Normalized Difference Vegetation Index (NDVI) essential for predicting environmental changes. The first study focuses on whether NDVI can improve model simulations of evapotranspiration for temperate Northern (>35°) regions. The second study focuses on whether NDVI can detect phenological changes in start of season (SOS) for high Northern (>60°) environments. The overall objectives of this research were to (1) develop a methodology for utilizing GLOBE data in NDVI research; and (2) provide a critical analysis of NDVI as a long-term monitoring tool for environmental change. GLOBE is an international partnership network of K-12 students, teachers, and scientists working together to study and understand the global environment. The first study utilized data collected by one GLOBE school in Greenville, Pennsylvania and the second utilized phenology observations made by GLOBE students in Alaska. Results from the first study showed NDVI could predict transpiration periods for environments like Greenville, Pennsylvania. In phenological terms, these environments have three distinct periods (QI, QII, and QIII). QI reflects onset of the growing season (mid March--mid May) when vegetation is greening up (NDVI 0.60). Results from the second study showed that a climate threshold of 153 +/- 22 growing degree days was a better predictor of SOS for Fairbanks than a NDVI threshold applied to temporal AVHRR and MODIS datasets. Accumulated growing degree days captured the interannual variability of SOS better than the NDVI threshold and most closely resembled actual SOS observations made by GLOBE students. Overall, biweekly composites and effects of clouds, snow, and conifers limit the ability of NDVI to monitor phenological changes in Alaska. Both studies did show that GLOBE data provides an important source of input and validation information for NDVI research.

    2012-01-01

    The emphasis in the international citizen-science, star-hunting campaign, GLOBE at Night, is in bringing awareness to the public on issues of light pollution. Light pollution threatens not only observatory sites and our "right to starlight", but can affect energy consumption, wildlife and health. GLOBE at Night has successfully reached a few 100,000 citizen-scientists. What has done in the last year to contribute to its success? • To promote the campaign via popular social media, GLOBE at Night created Facebook and Twitter pages. • Videos have been created for 4 out of 8 Dark Skies Rangers activities. • Sky brightness measurements can be submitted in real time with smart phones or tablets using the new Web application at www.globeatnight.org/webapp/. The location, date and time register automatically. • As a proto-type, an adopt-a-street program had people in Tucson take measurements every mile for the length of the street. Grid measurements canvassed the town, allowing for comparisons of light levels over time. • The increase to 2 campaigns in 2011 re-enforces these studies. In 2012, the campaign will be offered 4 times for 10 days a month: January 14-23, February 12-21, March 13-22 and April 11-20. • A new Web application (www.globeatnight.org/mapapp/) allows for mapping GLOBE at Night data points within a specified distance around a city or area of choice. The resulting maps are bookmarkable and shareable. • NOAO and Arizona Game and Fish Department started a project with GLOBE at Night data and bat telemetry to examine a dark skies corridor in Tucson where endangered bats fly. While providing these updates to the GLOBE at Night program, the presentation will highlight the education and outreach value of the program's resources and outcomes, lessons learned, successes and pitfalls in communicating awareness with the public and attracting young people to study science.

  8. Tool or Toy? Virtual Globes in Landscape Planning

    Directory of Open Access Journals (Sweden)

    Stephen R. J. Sheppard

    2011-10-01

    Full Text Available Virtual globes, i.e., geobrowsers that integrate multi-scale and temporal data from various sources and are based on a globe metaphor, have developed into serious tools that practitioners and various stakeholders in landscape and community planning have started using. Although these tools originate from Geographic Information Systems (GIS, they have become a different, potentially interactive and public tool set, with their own specific limitations and new opportunities. Expectations regarding their utility as planning and community engagement tools are high, but are tempered by both technical limitations and ethical issues [1,2]. Two grassroots campaigns and a collaborative visioning process, the Kimberley Climate Adaptation Project case study (British Columbia, illustrate and broaden our understanding of the potential benefits and limitations associated with the use of virtual globes in participatory planning initiatives. Based on observations, questionnaires and in-depth interviews with stakeholders and community members using an interactive 3D model of regional climate change vulnerabilities, potential impacts, and possible adaptation and mitigation scenarios in Kimberley, the benefits and limitations of virtual globes as a tool for participatory landscape planning are discussed. The findings suggest that virtual globes can facilitate access to geospatial information, raise awareness, and provide a more representative virtual landscape than static visualizations. However, landscape is not equally representative at all scales, and not all types of users seem to benefit equally from the tool. The risks of misinterpretation can be managed by integrating the application and interpretation of virtual globes into face-to-face planning processes.

  9. Locally Motivated GLOBE Investigations - A Key to Success

    Washburne, J. C.; Geery, W.

    2003-12-01

    The GLOBE program was set up to help students make a core set of environmental observations at or near their schools, report their data through the internet to share with other students and scientists, analyze their data both locally and globally, and use this knowledge to form a better understanding of their environment. While the GLOBE program has been successful promoting more meaningful data collection, many of the tools and much of the infrastructure available to schools to synthesize their observations are underused. Schools that integrate GLOBE protocols with locally motivated investigations are more likely to implement the higher-order analysis and synthesis components of the program. Indicators of a successful observational program are things like measurement persistence, high data quality, and regular data. Participation in community forums and student-based research projects are evidence of a successful integrated program. A locally motivated issue allows a school to mold their GLOBE investigations around a multi-faceted question that they have first-hand knowledge of, that is both relevant and engaging to their students, and that can be supported by local expertise. In contrast, many GLOBE investigations are designed around abstract, non-site specific, narrowly focused and externally analyzed questions that limit local involvement and motivation. The main focus of this presentation is a few case histories of successful local investigations that incorporated GLOBE soil and air temperature data-logger measurements. The main example is drawn from Mr. Geery's fifth grade class investigation of why temperature differences exist between a local river bottom area and the school, which is located several kilometers away and 100 meters higher.

    2017-12-01

    Citizen-science is a rewardingly inclusive way to bring awareness to the public on the disappearance of the starry night sky, its cause and solutions. Globe at Night (GaN) encourages citizen-scientists worldwide to record the brightness of the night sky. During ten-days per month of moonless evenings, children and adults match the appearance of a specific constellation with 7 star maps of progressively fainter stars found at www.globeatnight.org. They then submit their choice of star map in-situ using the "webapp" on a smart device. In eleven years of the program, over 160,000 observations from 180 countries have been contributed to a light pollution map. The GaN (open) database is a source of research projects. For example, students conducted research to understand the lesser long-nosed bats' avoidance of city center at night. With its analytical tools, Fieldscope will be a conduit for comparing GaN to other databases. On-the-fly mapping enables citizen-scientists to see observations immediately. There are 4 ways of taking measurements. The online app for data reporting is in 26 languages. STEM activities for young children and problem-based learning activities for older students were created to experience real-life scenarios: role-playing sea turtles hatching (misdirected by lights on shore) or analyzing an ISS image of Houston to estimate the wasted energy, cost and carbon footprint. In-situ and on-line workshops have been given on using GaN, as well as the activities. Our Facebook page exists to encourage dialogue and bring cutting edge news. To entice interest, we had monthly newsletters and serial podcasts starring the Dark Skies Crusader. GaN has been part of special campaigns like with the National Park Service, the National Geographic BioBlitz and Tucson in 2011. We have built a community of practitioners in various ways worldwide and have metrics on behavioral changes. To maintain the community and create new partnerships, we have teamed with Sci

    2017-12-01

    The spread of disease vectors, including mosquitoes, is an increasingly significant global environmental issue driven by a warming climate. In 2017, the GLOBE Observer Program launched a new citizen science initiative to map mosquito habitats using the free GLOBE Observer App for smart phones and tablets. The app guides people to identify mosquito larvae and breeding sites, and then once documented, to eliminate or treat the site to prevent further breeding. It also gives citizen scientists the option to identify the mosquito larvae species to determine whether it is one of three genera that potentially could transmit Zika, dengue fever, yellow fever, chikungunya, and other diseases. This data is uploaded to an international database that is freely available to the public and science community. GLOBE Observer piloted the initiative with educators in the United States, Brazil, and Peru, and it is now open for global participation. This presentation will discuss lessons learned in the pilot phase as well as plans to implement the initiative worldwide in partnership with science museums and science centers. GLOBE Observer is the non-student citizen science arm of the Global Learning and Observations to Benefit the Environment (GLOBE) Program, a long-standing, international science and education program that provides students and citizen scientists with the opportunity to participate in data collection and the scientific process, and contribute meaningfully to our understanding of the Earth system and global environment. GLOBE Observer data collection also includes cloud cover and cloud type and land cover/land use (in late 2017).

    Weeraratne, D. S.; Rogers, D. B.

    2011-12-01

    Instructional techniques for study of seismology are greatly enhanced by three dimensional (3D) visualization. Seismic rays that pass through the Earth's interior are typically viewed in 2D slices of the Earth's interior. Here we present the use of a 3D Earth globe manufactured by Real World Globes. This globe displays a dry-erase high resolution glossy topography and bathymetry from the Smith and Sandwell data archives at its surface for interactive measurements and hands-on marking of many seismic observations such as earthquake locations, source-receiver distances, surface wave propagation, great circle paths, ocean circulation patterns, airplane trajectories, etc.. A new interactive feature (designed collaboratively with geoscientists) allows cut away and disassembly of sections of the exterior shell revealing a full cross section depicting the Earth's interior layers displayed to scale with a dry-erase work board. The interior panel spins to any azimuth and provides a depth measurement scale to allow exact measurements and marking of earthquake depths, true seismic ray path propagation, ray path bottoming depths, shadow zones, and diffraction patterns. A demo of this globe and example activities will be presented.

    2017-12-01

    Place-based education - helping students make connections between themselves, their community, and their local environment - is an important tool to help young learners understand their regional climate and start to learn about climate and environmental change. Elementary GLOBE storybooks and learning activities allow opportunities for place-based education instructional strategies about climate. In particular, two modules in the Elementary GLOBE unit - Seasons and Climate - provide opportunities for students to explore their local climate and environment. The storybooks and activities also make connections to other parts of elementary curriculum, such as arts, geography, and math. Over the long term, place-based education can also encourage students to be stewards of their local environment. A strong sense of place may help students to see themselves as stakeholders in their community and its resilience. In places that are particularly vulnerable to the impacts of climate and environmental change and the economic, social, and environmental tradeoffs of community decisions, helping young students developing a sense of place and to see the connection between Earth science, local community, and their lives can have a lasting impact on how a community evolves for decades to come. Elementary GLOBE was designed to help elementary teachers (i.e., grades K-4) integrate Earth system science topics into their curriculum as they teach literacy skills to students. This suite of instructional materials includes seven modules. Each module contains a science-based storybook and learning activities that support the science content addressed in the storybooks. Elementary GLOBE modules feature air quality, climate, clouds, Earth system, seasons, soil, and water. New eBooks allow students to read stories on computers or tablets, with the option of listening to each story with an audio recording. A new Elementary GLOBE Teacher Implementation Guide, published in 2017, provides

  5. Determining Light Pollution of the Global Sky: GLOBE at Night

    2006-05-01

    GLOBE at Night is an international science event designed to observe and record the visible stars as a means of measuring light pollution in a given location. Increased and robust understanding of our environment requires learning opportunities that take place outside of the conventional K-12 classroom and beyond the confines of the school day. This hands-on learning activity extended the traditional classroom and school day last March with a week of nighttime sky observations involving teachers, students and their families. The quality of the night sky for stellar observations is impacted by several factors including human activities. By observing cloud cover and locating specific constellations in the sky, students from around the world learned how the lights in their community contribute to light pollution, exploring the relationship between science, technology and their society. Students learned that light pollution impacts more than just the visibility of stars at night. Lights at night impact both the biology and ecology of many species in our environment. Students were able to participate in this global scientific campaign by submitting their observations through an online database, allowing for authentic worldwide research and analysis by participating scientists. Students and their families learned how latitude and longitude coordinates provide a location system to map and analyze the observation data submitted from around the globe. The collected data is available online for use by students, teachers and scientists worldwide to assess how the quality of the night sky varies around the world. This session will share how students and scientists across the globe can explore and analyze the results of this exciting campaign. GLOBE at Night is a collaborative effort sponsored by The GLOBE Program, the National Optical Astronomy Observatory (NOAO), Centro de Apoyo a la Didactica de la Astronomia (CADIAS), Windows to the Universe, and ESRI.

    The International Astronomical Union (IAU) will be coordinating extensive activities to raise awareness of light pollution through running the Cosmic Light theme of the International Year of Light (IYL2015) and by partnering in particular with the popular Globe at Night program.Globe at Night (www.globeatnight.org) is an international campaign to raise public awareness of the impact of light pollution by having people measure night-sky brightness and submit observations in real-time with smart phone or later with a computer. In 2015, Globe at Night will run for 10-nights each month, an hour after sunset til before the Moon rises. Students can use the data to monitor levels of light pollution around the world, as well as understand light pollution's effects on energy consumption, plants, wildlife, human health and our ability to enjoy a starry night sky.Since its inception in 2006, more than 115,000 measurements from 115 countries have been reported. The last 9 years of data can be explored with Globe at Night's interactive world map or with the 'map app' to view a particular area. A spreadsheet of the data is downloadable from any year. One can compare Globe at Night data with a variety of other databases to see, for example, how light pollution affects the foraging habits of bats.To encourage public participation in Globe at Night during IYL2015, each month will target an area of the world that habitually contributes during that time. Special concerns for how light pollution affects that area and solutions will be featured on the Globe at Night website (www.globeatnight.org), through its Facebook page, in its newsletter or in the 365DaysofAstronomy.org podcasts.Twice during IYL there will be a global Flash Mob event, one on Super Pi Day (March 14, 2015) and a second in mid-September, where the public will be invited to take night-sky brightness measurements en masse. In April, the International Dark-Sky Week hosted by the International Dark-Sky Association will be

    Full Text Available Jan Felkl company from Roztoky (Roztok near Prague manufactured globes in seventeen language versions, since 1861 also in Polish language. The company was active until 1952, but it ceased to manufacture Polish-language globes as early as in 1914. In the aftermath of the First World War, and with the development of printing business, the demand for Czech globes shrank. It is difficult to estimate the overall output of Polish- language globes manufactured by Felkl’s company throughout the 53 years it operated. From catalogues and the surviving globes we know that terrestrial globes in six sizes, folding globes in two sizes, celestial globes (probably in four sizes, as well as telluria, lunaria and planetaria were manufactured for the Polish market. It is difficult to decide how many editions of individual types of globes were issued. Polish names were compiled by Franciszek Waligórski (one globe and Mirosław Suchecki. Only 28 globes have survived to this day, including one celestial globe. Most of them are globes of an 8-inch diameter, approved by the Austrian ministries as teaching aids for schools. Nearly half of the surviving globes date from the years 1894–1914. Only ten items are in museums.

Observational cross-sectional study including 88 eyes of 68 patients. In this study, 23 non-arteritic anterior ischemic optic neuropathy eyes, 17 fellow unaffected eyes, 25 primary open-angle glaucoma eyes, and 23 age-matched control eyes were included. Peripapillary retinal nerve fiber layer thickness and optic disk area were evaluated. Bruch's membrane opening diameter, optic cup depth, anterior lamina cribrosa depth, and prelaminar tissue thickness were assessed. Non-arteritic anterior ischemic optic neuropathy and primary open-angle glaucoma eyes had similar visual field mean deviation and peripapillary retinal nerve fiber layer thickness (P = 0.6 and P = 0.56, respectively). Bruch's membrane opening diameter was significantly larger in primary open-angle glaucoma eyes than in control eyes (P = 0.02). Lamina cribrosa and disk cup were deeper in eyes with primary open-angle glaucoma than both control and non-arteritic anterior ischemic optic neuropathy eyes (P open-angle glaucoma eyes than in non-arteritic anterior ischemic optic neuropathy eyes (P opening diameter was found in primary open-angle glaucoma eyes compared with control eyes. This issue has clinical implications because Bruch's membrane opening has been considered a stable reference for disk-related measures.

    The University of Alaska Southeast is currently implementing a sensor web identified as the SouthEast Alaska MOnitoring Network for Science, Telecommunications, Education, and Research (SEAMONSTER). SEAMONSTER is operating in the partially glaciated Mendenhall and Lemon Creek Watersheds, in the Juneau area, on the margins of the Juneau Icefield. These watersheds are studied for both 1. long term monitoring of changes, and 2. detection and analysis of transient events (such as glacier lake outburst floods). The heterogeneous sensors (meteorologic, dual frequency GPS, water quality, lake level, etc), power and bandwidth constraints, and competing time scales of interest require autonomous reactivity of the sensor web. They also present challenges for operational management of the sensor web. The harsh conditions on the glaciers provide additional operating constraints. The tight integration of the sensor web and virtual global enabling technology enhance the project in multiple ways. We are utilizing virtual globe infrastructures to enhance both sensor web management and data access. SEAMONSTER utilizes virtual globes for education and public outreach, sensor web management, data dissemination, and enabling collaboration. Using a PosgreSQL with GIS extensions database coupled to the Open Geospatial Consortium (OGC) Geoserver, we generate near-real-time auto-updating geobrowser files of the data in multiple OGC standard formats (e.g KML, WCS). Additionally, embedding wiki pages in this database allows the development of a geospatially aware wiki describing the projects for better public outreach and education. In this presentation we will describe how we have implemented these technologies to date, the lessons learned, and our efforts towards greater OGC standard implementation. A major focus will be on demonstrating how geobrowsers and virtual globes have made this project possible.

    2007-01-01

    A pneumatic control valve is a piping element that controls the volumetric flow rate and pressure of a fluid: it is necessary to analyze the characteristics of the forces with respect to the opening of the valve in order to evaluate its operating performance. The forces occurring during operation are: resisting force and actuator force, where the load resistance is mostly affected by the fluid pressure difference of the valve. In this study, a force balance equation derived from the equilibrium relationship between the resisting force and the actuator force of an unbalanced globe valve is proposed, and the force balance equations are used to model the dynamic equations of a pneumatic unbalanced globe valve installed in nuclear power plants. A CFD analysis is also carried out to evaluate the pressure distribution and forces acting on the top and bottom planes of the valve plug. The results of this analysis have been verified through experimentation. This study has shown that the fluid pressure difference between the inlet and outlet of the valve, measured from the force balance equation of an unbalanced valve, should actually be examined with the fluid-pressure difference between the top and bottom side of the valve plug

    Traditionally, globe artichoke cultivation in the Mediterranean basin is based on monoculture and on use of high amounts of nitrogen fertiliser. This raises issues regarding its compatibility with sustainable agriculture. We studied the effect of one typical conventional (CONV) and two alternative cropping systems [globe artichoke in sequence with French bean (NCV1), or in biannual rotation (NCV2) with cauliflower and with a leguminous cover crop in inter-row spaces] on yield, polyphenol and mineral content of globe artichoke heads over two consecutive growing seasons. NCV2 showed statistical differences in terms of fresh product yield with respect to the monoculture systems. In addition, the dihydroxycinnamic acids and dicaffeoylquinic acids of non-conventional samples were one-fold significantly higher than the conventional one. All the samples reported good mineral content, although NCV2 achieved a higher Fe content than conventional throughout the two seasons. After two and three dates of sampling, the CONV samples showed the highest levels of K content. In our study, an acceptable commercial yield and quality of 'Spinoso sardo' were achieved by shifting the common conventional agronomic management to more sustainable ones, by means of an accurate choice of cover crop species and rotations introduced in the systems. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

In the former 50 years, feasible countermeasures such as deepenung of scientific knowkedges, promotion of worldwide energy saving, introduction of clean energy, development of revolutional environmental technology, expansion of CO {sub 2} absorbing sources, and technological development of energy for the next generation will be executed continuously. In the latter 50 years, the gas exhausting amount resulting the green house effect will be reduced and suppressed from these results. Owing to these measures, the reduction of gas resulting the greenhouse effect which exceeds the expectation, can clean the globe after 100 years because the cleaning results will be incorporated into the natural circulation and the green globe will be reincarnated. 1 fig., 1 tab

    Aquaporins (AQP) are channels in the cell membrane that mainly facilitate a passive transport of water. In the eye, AQPs are expressed in the ciliary body and retina and may contribute to the pathogenesis of glaucoma and optic neuropathy. We investigated the expression of AQP1, AQP3, AQP4, AQP5......, AQP7 and AQP9 in human glaucoma eyes compared with normal eyes. Nine glaucoma eyes were examined. Of these, three eyes were diagnosed with primary open angle glaucoma; three eyes had neovascular glaucoma; and three eyes had chronic angle-closure glaucoma. Six eyes with normal intraocular pressure...... and without glaucoma were used as control. Immunohistochemistry was performed using antibodies against AQP1, AQP3, AQP4, AQP5, AQP7 and AQP9. For each specimen, optical densities of immunoprecipitates were measured using Photoshop and the staining intensities were calculated. Immunostaining showed labelling...

    2017-04-01

    Virtual globes — programs implementing interactive three-dimensional (3D) models of planets — are increasingly used in geo- and planetary sciences. We develop a web-system of virtual morphometric globes. As the initial data, we used the following global digital elevation models (DEMs): (1) a DEM of the Earth extracted from SRTM30_PLUS database; (2) a DEM of Mars extracted from the Mars Orbiter Laser Altimeter (MOLA) gridded data record archive; and (3) A DEM of the Moon extracted from the Lunar Orbiter Laser Altimeter (LOLA) gridded data record archive. From these DEMs, we derived global digital models of the following 16 local, nonlocal, and combined morphometric variables: horizontal curvature, vertical curvature, mean curvature, Gaussian curvature, minimal curvature, maximal curvature, unsphericity curvature, difference curvature, vertical excess curvature, horizontal excess curvature, ring curvature, accumulation curvature, catchment area, dispersive area, topographic index, and stream power index (definitions, formulae, and interpretations can be found elsewhere [1]). To calculate local morphometric variables, we applied a finite-difference method intended for spheroidal equal angular grids [1]. Digital models of a nonlocal and combined morphometric variables were derived by a method of Martz and de Jong adapted to spheroidal equal angular grids [1]. DEM processing was performed in the software LandLord [1]. The calculated morphometric models were integrated into the testing version of the system. The following main functions are implemented in the system: (1) selection of a celestial body; (2) selection of a morphometric variable; (3) 2D visualization of a calculated global morphometric model (a map in equirectangular projection); (4) 3D visualization of a calculated global morphometric model on the sphere surface (a globe by itself); (5) change of a globe scale (zooming); and (6) globe rotation by an arbitrary angle.

  12. Investigation on Aerodynamic Noise Evaluation and Attenuation In a Globe Valve using CFD Analysis

    2016-03-01

    Full Text Available Noise pollution will soon become the third greatest menace to the human environment after air and water pollution. Since noise is a by-product of energy conversion, there will be increasing noise as the demand for energy for transportation, power, food, and chemicals increases. In the field of control equipment, noise produced by valves has become a focal point of attention .In this paper aerodynamic noise evaluation of a globe valve was carried out  using a three dimensional Computational Fluid Dynamic technique(CFD. The results obtained from numerical analysis are compared with the experimental measurements and are found   to be in good agreement. Reduction in sound pressure level was achieved by doubling the number of flow passages in the cage at full open condition and at the same operating conditions. Hence sound attenuation is established by changing the cage configuration with no change in total area of flow passage in the cage

    Numerical simulations of eye globes often rely on topographies that have been measured in vivo using devices such as the Pentacam or OCT. The topographies, which represent the form of the already stressed eye under the existing intraocular pressure, introduce approximations in the analysis. The accuracy of the simulations could be improved if either the stress state of the eye under the effect of intraocular pressure is determined, or the stress-free form of the eye estimated prior to conducting the analysis. This study reviews earlier attempts to address this problem and assesses the performance of an iterative technique proposed by Pandolfi and Holzapfel [1], which is both simple to implement and promises high accuracy in estimating the eye's stress-free form. A parametric study has been conducted and demonstrated reliance of the error level on the level of flexibility of the eye model, especially in the cornea region. However, in all cases considered 3-4 analysis iterations were sufficient to produce a stress-free form with average errors in node location <10(-6)mm and a maximal error <10(-4)mm. This error level, which is similar to what has been achieved with other methods and orders of magnitude lower than the accuracy of current clinical topography systems, justifies the use of the technique as a pre-processing step in ocular numerical simulations.

    2011-09-01

    The GLOBE at Night database now contains over 52,000 observations from the five annual two-week campaigns. It can be used as a resource to explore various issues related to light pollution and our environment. Students can compare data over time to look for changes and trends. For example, they can compare the data to population density or with nighttime photography and spectroscopy of lights. The data can be used in a lighting survey, to search for dark sky oases or to monitor ordinance compliance. Students can study effects of light pollution on animals, plants, human health, safety, security, energy consumption, and cost. As an example, we used data from the GLOBE at Night project and telemetry tracking data of lesser long-nosed bats obtained by the Arizona Game and Fish Department to study the effects of light pollution on the flight paths of the bats between their day roosts and night foraging areas around the city of Tucson, AZ. With the visual limiting magnitude data from GLOBE at Night, we ran a compositional analysis with respect to the bats' flight paths to determine whether the bats were selecting for or against flight through regions of particular night sky brightness levels. We found that the bats selected for the regions in which the limiting sky magnitudes fell between the ranges of 2.8-3.0 to 3.6-3.8 and 4.4-4.6 to 5.0-5.2, suggesting that the lesser long-nosed bat can tolerate a fair degree of urbanization. We also compared this result to contour maps created with digital Sky Quality Meter (http://www.unihedron.com) data.

    2014-07-01

    To describe the normal ultrasonographic biometry of the Persian cat's eyes using B-mode ultrasonography. In a cross-sectional study, 20 healthy Persian cats with no history of previous ophthalmic disease were examined. Ocular biometry of the left and right eyes was measured using B-mode ultrasonography. Comparison of the average measurements between left and right eyes and between vertical and horizontal planes was performed using paired-sample t test. Correlation of ocular parameters with sex, age, head circumference and eye colour was evaluated. Mean ± standard deviation (SD) measurements of the ocular structures of anterior chamber, lens thickness, vitreous chamber and anterior to posterior dimension of the globe in 40 eyes were 4.1 ± 0.7, 7.7 ± 0.5, 8.2 ± 0.4 and 20.7 ± 1.0 mm, respectively. No significant difference was found between the ocular biometry of the left and right eyes or the horizontal and vertical planes. Of the ocular parameters, the following had a significant positive correlation with head circumference: axial globe length, anterior chamber and lens thickness. The vitreous body had a positive correlation with age. Regarding the breed predisposition of Persian cats to ocular problems, the present study provides baseline information for further clinical investigations of ocular abnormalities using B-mode ultrasonography. © 2014 Australian Veterinary Association.

    2002-01-01

    Heritage College, located on the Yakama Indian Reservation in south central Washington state, serves a multicultural, underserved, rural population and trains teachers to staff the disadvantaged school districts on and surrounding the reservation. In-service teachers and pre-service teachers in the area show strength in biology but have weak backgrounds in chemistry and mathematics. We are addressing this problem by providing a 2-year core of courses for 3 groups of 25 students (15 pre-service and 10 in-service teachers) using GLOBE to teach integrated physical science and mathematics. At the conclusion of the program, the students will qualify for science certification by Washington State. Water resources are the focal point of the curriculum because it is central to life in our desert area. The lack or excess of water, its uses, quality and distribution is being studied by using GIS, remote sensing and historical records. Students are learning the methodology to incorporate scientific protocols and data into all aspects of their future teaching curriculum. In addition, in each of the three years of the project, pre-service teachers attended a seminar series during the fall semester with presentations by collaborators from industry, agriculture, education and government agencies. Students used NASA educational materials in the presentations that they gave at the conclusion of the seminar series. All pre- and in-service teachers continue to have support via a local web site for Heritage College GLOBE participants.

    The filamentary discharge seen within commercial plasma globes is commonly enjoyed yet not well understood. Here, we investigate the discharge properties of a plasma globe using a variable high voltage amplifier. We find that increasing voltage magnitude increases the number of filaments while leaving their individual structure basically unchanged, a result typical of dielectric barrier discharges. The frequency of the voltage also affects filament population but more significantly changes filament structure, with more diffuse filaments seen at lower frequencies. Voltage polarity is observed to be important, especially at lower frequencies, where for negative-gradient voltages the discharge is more diffuse, not filamentary. At late stages of the discharge circular structures appear and expand on the glass boundaries. We find no trend of discharge speed with respect to voltage variables, though this may be due to manufacturer sample-to-sample variation. Each voltage cycle the discharge expands outward at ∼10–15 km/s, a speed significantly higher than the estimated electron drift yet considerably lower than that observed for most streamers. We discuss the physics of these observations and their relation to similar discharges that can be found within nature and industry

  7. Eye Contricks

    Directory of Open Access Journals (Sweden)

    N Wade

    2011-04-01

    Full Text Available Icons are eye-cons: they provide a distillation of a complex object or idea into a simple pictorial shape. They create the impression of representing that which cannot be presented. Even at the level of the photograph, the links between icon and object are tenuous. The dimension of distance or depth is missing from the icon, and this alone introduces all manner of potential ambiguities. The history of art can be considered as an exploration of the missing link between icon and object. Eye-cons are more honest—they are tricks of vision so that what is seen does not necessarily correspond to what is presented. They are visual allusions rather than visual illusions, although they can display illusory effects. At its broadest, icon can be equated with image. The concept of image has thrived on its vagueness, and so attempts have been made to refine it. An icon corresponds to an optical image: it shares some of the projective characteristics of the object represented. Written words are also icons but they do not resemble the objects they represent—they are stylised or conventional rather than spatialised and projective. Words and images were set in delightful opposition by René Magritte (1898-1967 in a series of pipe paintings, and he also played on the theme of the arbitrariness of the verbal labels assigned to objects. What is surprising is that Magritte did not apply his painterly skills to transforming the word shapes he used. A similar reluctance to transform the typefaces pervades visual poetry. My interests are in the visual rather than the poetic dimension, and I will present a range of my own eye contricks which play with letter and word shapes in a variety of ways.

    2005-12-01

    NASA and the NSF, the sponsoring Federal agencies for the GLOBE Program, are seeking the participation of science teams who are working at the cutting edge of Earth systems science in large integrated Earth systems science programs. Connecting the GLOBE concept and structure with NASA and NSF's leading Earth systems science programs will give GLOBE schools and students access to top scientists, and expose them to programs that have been designated as scientific priorities. Students, teachers, parents, and their communities will be able to see how scientists of many disciplines work together to learn about the Earth system. The GLOBE solicitation released by the NSF targets partnerships between GLOBE and NSF/NASA-funded integrated Earth systems science programs. This presentation will focus on the goals and requirements of the NSF solicitation. Proponents will be expected to provide ways for the GLOBE community to interact with a group of scientists from their science programs as part of a wider joint Earth systems science educational strategy (the sponsoring agencies', GLOBE's, and the proposing programs'). Teams proposing to this solicitation must demonstrate: - A focus on direct connections with major NSF Geosciences and/or Polar Programs and/or NASA Earth-Sun research programs that are related to Earth systems science; - A demonstrable benefit to GLOBE and to NSF Geosciences and/or Polar Programs or NASA Earth-Sun education goals (providing access to program researchers and data, working with GLOBE in setting up campaigns where possible, using tested GLOBE or non-GLOBE protocols to the greatest extent possible, actively participating in the wider GLOBE community including schools, among other goals); - An international component; - How the existing educational efforts of the large science program will coordinate with GLOBE; - An Earth systems science education focus, rather than a GLOBE protocol-support focus; - A rigorous evaluation and assessment component

    2016-03-01

    In recent years, several research groups have developed automatic algorithms to detect diabetic retinopathy (DR) in individuals with diabetes (DM), using digital retinal images. Studies have indicated that diabetics have 1.5 times the annual risk of developing primary open angle glaucoma (POAG) as do people without DM. Moreover, DM patients have 1.8 times the risk for age-related macular degeneration (AMD). Although numerous investigators are developing automatic DR detection algorithms, there have been few successful efforts to create an automatic algorithm that can detect other ocular diseases, such as POAG and AMD. Consequently, our aim in the current study was to develop a comprehensive eye evaluation algorithm that not only detects DR in retinal images, but also automatically identifies glaucoma suspects and AMD by integrating other personal medical information with the retinal features. The proposed system is fully automatic and provides the likelihood of each of the three eye disease. The system was evaluated in two datasets of 104 and 88 diabetic cases. For each eye, we used two non-mydriatic digital color fundus photographs (macula and optic disc centered) and, when available, information about age, duration of diabetes, cataracts, hypertension, gender, and laboratory data. Our results show that the combination of multimodal features can increase the AUC by up to 5%, 7%, and 8% in the detection of AMD, DR, and glaucoma respectively. Marked improvement was achieved when laboratory results were combined with retinal image features.

    2018-01-01

    Human trafficking is a global issue, with survivors representing all genders, ages, races, ethnicities, religions, and countries. However, little research exists that identifies effective practices in supporting survivors of human trafficking. The research that does exist is Western-centric. To fill this gap in the literature, the goal of this research was to understand practices used throughout the globe with adult human trafficking survivors. A qualitative approach was utilized. Providers from 26 countries, across six different continents, were interviewed to allow for a comprehensive and multi-faceted understanding of practices in working with survivors. Participants identified utilizing an empowerment-based, survivor, and human life-centered approach to working with survivors, emphasized the importance of engaging in community level interventions, and highlighted the importance of government recognition of human trafficking. Findings provide information from the perspective of advocates on best practices in the field that can be used by agencies to enhance human trafficking programming.

  12. An Optimization Method for Virtual Globe Ocean Surface Dynamic Visualization

    Directory of Open Access Journals (Sweden)

    HUANG Wumeng

    2016-12-01

    Full Text Available The existing visualization method in the virtual globe mainly uses the projection grid to organize the ocean grid. This special grid organization has the defects in reflecting the difference characteristics of different ocean areas. The method of global ocean visualization based on global discrete grid can make up the defect of the projection grid method by matching with the discrete space of the virtual globe, so it is more suitable for the virtual ocean surface simulation application.But the available global discrete grids method has many problems which limiting its application such as the low efficiency of rendering and loading, the need of repairing grid crevices. To this point, we propose an optimization for the global discrete grids method. At first, a GPU-oriented multi-scale grid model of ocean surface which develops on the foundation of global discrete grids was designed to organize and manage the ocean surface grids. Then, in order to achieve the wind-drive wave dynamic rendering, this paper proposes a dynamic wave rendering method based on the multi-scale ocean surface grid model to support real-time wind field updating. At the same time, considering the effect of repairing grid crevices on the system efficiency, this paper presents an efficient method for repairing ocean surface grid crevices based on the characteristics of ocean grid and GPU technology. At last, the feasibility and validity of the method are verified by the comparison experiment. The experimental results show that the proposed method is efficient, stable and fast, and can compensate for the lack of function of the existing methods, so the application range is more extensive.

    2017-08-01

    This paper reports in detail on the image-based modelling and unwrapping approach used to create a two-dimensional projected map of an astonishing ostrich egg globe from AD 1504. This miniature egg globe is not only the oldest extant engraved globe, but it is also the oldest post-Columbian globe of the world and the first ever to depict Newfoundland and many other territories. The intention of digitally recording the surface geometry and colour of this unique artefact was to portray the original layout of the world map used by the Florentine Renaissance artist to make this globe. In addition, it was expected to substantiate iconographical details, which are hard to study at its scale of 1:80,000,000. The ostrich egg globe is the prototype of the Lenox Globe kept at the New York Public Library. The latter is very beneficial to examine how the egg globe looked like before being glued together at its equator. On the other hand, unfolding the map engraved in the ostrich egg halves enables a more detailed study of the remarkable details visible on both globes, since the engravings on the quasi-white egg surface are much easier to discern than those of the highly reflective red copper Lenox Globe. Finally, a detailed study of the unwrapped 3D surface is essential to learn more about the world vision of its creator and the incredible efforts that went into making this globe. Thanks to some particular pictographic details as well as the way in which the engravings are applied (by a left-handed person), the globe artist can be identified as Leonardo da Vinci.

    Highlights: • PCGV utilizes pressure difference to control the action of the valve core. • Three different opening processes with the same spring stiffness are analyzed. • Valve core’s displacements with different spring stiffness are analyzed. • The best design point of spring stiffness and inlet pressure is obtained. • The selection formula for the design of PCGV is generalized. - Abstract: The pilot-control globe valve (PCGV) is a new kind valve with simple structures and low driving energy consumption. It can utilize the pressure difference before and after the valve to control the action of the valve core. However, systematic theoretical research and numerical analysis are deficient at present. In this paper, the mathematical model of PCGV is established and Computational Fluid Dynamics (CFD) method is employed to numerically simulate its dynamic characteristics. Through the analysis of the internal flow field distribution, its working principle is verified. Then three different opening processes with the same spring stiffness are analyzed under different static inlet pressures, and the best design point is obtained by studying the characteristic curves of the valve core’s displacement. The relationship of static inlet pressure and the valve core’s displacement is summarized and the selection formula for the valve design is generalized which can reduce the various design work for further optimization and engineering applications of PCGV

  12. Eye retraction and rotation during Corvis ST 'air puff' intraocular pressure measurement and its quantitative analysis.

    Boszczyk, Agnieszka; Kasprzak, Henryk; Jóźwik, Agnieszka

    2017-05-01

    The aim of this study was to analyse the indentation and deformation of the corneal surface, as well as eye retraction, which occur during air puff intraocular pressure (IOP) measurement. A group of 10 subjects was examined using a non-contact Corvis ST tonometer, which records image sequences of corneas deformed by an air puff. Obtained images were processed numerically in order to extract information about corneal deformation, indentation and eyeball retraction. The time dependency of the apex deformation/eye retraction ratio and the curve of dependency between apex indentation and eye retraction take characteristic shapes for individual subjects. It was noticed that the eye globes tend to rotate towards the nose in response to the air blast during measurement. This means that the eye globe not only displaces but also rotates during retraction. Some new parameters describing the shape of this curve are introduced. Our data show that intraocular pressure and amplitude of corneal indentation are inversely related (r 8  = -0.83, P = 0.0029), but the correlation between intraocular pressure and amplitude of eye retraction is low and not significant (r 8  = -0.24, P = 0.51). The curves describing corneal behaviour during air puff tonometry were determined and show that the eye globe rotates towards the nose during measurement. In addition, eye retraction amplitudes may be related to elastic or viscoelastic properties of deeper structures in the eye or behind the eye and this should be further investigated. Many of the proposed new parameters present comparable or even higher repeatability than the standard parameters provided by the Corvis ST. © 2017 The Authors Ophthalmic & Physiological Optics © 2017 The College of Optometrists.

    For better clinical analysis in ophthalmic brachytherapy dosimetry, there is a need for the dose determination in different parts of the eye, so simulating the eye and defining the material of any parts of that, is helpful for better investigating dosimetry in human eye. However in brachytherapy dosimetry, it is common to consider the water phantom as human eye globe. In this work, a full human eye is simulated with MCNP-4C code by considering all parts of the eye like; lens, cornea, retina, choroid, sclera, anterior chamber, optic nerve, bulk of the eye comprising vitreous body and tumour. The average dose in different parts of this full model of human eye is determined and the results are compared with the dose calculated in water phantom. The central axes depth dose and the dose in whole of the tumour for these two simulated eye model are calculated too, and the results are compared. At long last, as the aim of this work is comparing the result of investigating dosimetry between two water phantom as human eye and simulated eye globe, the ratios of the absorbed dose by the healthy tissues to the absorbed dose by the tumour are calculated in these simulations and the comparison between results is done eventually.

    Inclusion, diversity, underrepresented groups, underserved populations...the key words and phrases that represent the students, we, as science education professionals, want to reach and encourage to enter the geoscience pipeline. Wanting to do this is one thing and having the skills to succeed is very different. It is also one that the GLOBE Program, an international science and education program, is working on as a community. GLOBE encourages students from around the world to participate in authentic scientific research of the Earth system. Students use scientific protocols to explore their local environments, compare their findings with other GLOBE schools both in the U.S. and in other participating countries, and then share their findings via the GLOBE.gov website. In the last year, two initiatives, six face-to-face Student Research Symposia and two diversity-focused GLOBE Partner Bootcamps, set the GLOBE community of Partners, teachers and students on the path to being able to address this challenge. This presentation will include the framework for the student research symposia, the barriers the leadership team faced when recruiting and getting students there and the lessons learned. Agendas for the GLOBE Partner Bootcamps will be shared to demonstrate how facilitators supplemented a standard GLOBE Partner workshop to model a more inclusive environment, along with future improvements to the format.

  19. Gender-Role Portrayals in Television Advertising Across the Globe.

    Matthes, Jörg; Prieler, Michael; Adam, Karoline

    Although there are numerous studies on gender-role portrayals in television advertising, comparative designs are clearly lacking. With content analytical data from a total of 13 Asian, American, and European countries, we study the stereotypical depiction of men and women in television advertisements. Our sample consists of 1755 ads collected in May 2014. Analyzing the gender of the primary character and voiceover, as well as the age, associated product categories, home- or work setting, and the working role of the primary character, we concluded that gender stereotypes in TV advertising can be found around the world. A multilevel model further showed that gender stereotypes were independent of a country's gender indices, including Hofstede's Masculinity Index, GLOBE's Gender Egalitarianism Index, the Gender-related Development Index, the Gender Inequality Index, and the Global Gender Gap Index. These findings suggest that gender stereotyping in television advertising does not depend on the gender equality prevalent in a country. The role of a specific culture in shaping gender stereotypes in television advertising is thus smaller than commonly thought.

  20. Do Interactive Globes and Games Help Students Learn Planetary Science?

    2016-01-01

    The popularity of animations and interactive visualizations in undergraduate science education might lead one to assume that these teaching aids enhance student learning. We tested this assumption for the case of the Google Earth virtual globe with a comparison of control and treatment student groups in a general education class of over 370 students at a large public university. Earth and Planetary Science course content was developed in two formats: using Keyhole Markup Language (KML) to create interactive tours in Google Earth (the treatment group) and Portable Document Format (PDF) for on-screen reading (the control group). The PDF documents contained identical text and images to the placemark balloons or "tour stops" in the Google Earth version. Some significant differences were noted between the two groups based on the immediate post-questionnaire with the KML students out-performing the PDF students, but not on the delayed measure. In a separate but related project, we undertake preliminary investigations into methods of teaching basic concepts in planetary mantle convection using numerical simulations. The goal of this project is to develop an interface with a two-dimensional finite element model that will allow students to vary parameters such as the temperatures assigned to the boundaries of the model domain, to help them actively explore important variables that control convection.

    2013-01-01

    The globe artichoke (Cynara cardunculus L. var. scolymus) is a perennial plant cultivated in the Mediterranean region and the Americas for its edible young flower heads. Although vegetative propagation by offshoots or by "ovoli" (underground dormant axillary buds) has been the primary method of propagation, the potential for the diffusion of diseases and the phenotypic variability can be very high. The propagation of this species by axillary shoot proliferation from in vitro-cultured meristems produces systemic pathogen-free plants and a higher multiplication rate as compared to that obtained by conventional agamic multiplication. Axillary shoot proliferation can be induced from excised shoot apices cultured on Murashige and Skoog agar solidified medium supplemented with various concentrations of cytokinins and auxins, depending on genotype. For the production of virus-free plants, meristems, 0.3-0.8 mm long are excised from shoot apices and surface sterilized. The transfer of artichoke microshoots to a medium lacking cytokinins or with low cytokinin concentration is critical for rooting. Adventitious roots develop within 3-5 weeks after transfer to root induction MS medium containing NAA or IAA at various concentrations. However, in vitro rooting frequency rate is dependent on the genotype and the protocol used. Acclimatization of in vitro microshoots having 3-4 roots is successfully accomplished; plantlets develop new roots in ex vitro conditions and continue to grow.

  5. Phenotypic variability in a population of globe artichoke

    Full Text Available The existence of variability is a prerequisite for genetic improvement in plants. Globe artichoke is a high nutritious vegetable with medical value, representing a profitable alternative for rural producers. This research was conducted with the aim of evaluating the phenotypic variability in a commercial cultivar of artichoke (Cynara cardunculus var. scolymus L established from seeds. Field plants were assessed when primary head reached commercial stage. An amount of 21 quantitative and 5 multicategoric characters were assessed. The quantitative data were submitted to multivariate analysis. For quantitative characters the distance between individuals varied from 3.0 to 50.9, revealing high intrapopulation variability. The greater relative contribution characters for genetic divergence were the primary head fresh mass (79.88% and bottom fresh mass (8.43%. This indicates the possibility of plant selection for head quality in this population. The clustering analysis through UPGMA method, based on quantitative characters, allowed the formation of five groups. For multicategoric traits, the similarity among individuals varied from 1.22% to 100%. Within the existing population variability, it was possible to select plants with superior quantitative traits desirable for in natura consumption, as primary head fresh weight and length, bottom fresh mass, bract basis length and width, as well as non-quantitative traits as round head shape, absence of thorn and presence of violet color in the head.

    Collaterals 2016 (third International Symposium on Collaterals to the Brain) was a multidisciplinary scientific conference focused on collateral circulation in acute ischemic stroke. Decisive challenges include generalizability of optimal triage and selection paradigms based on collateral status for definitive treatment of acute ischemic stroke, rapid dissemination of expert methods, and the urgent need to leverage networking opportunities for stroke science related to the hemodynamics of collaterals. The collaterome, or individual capacity to offset ischemia in the brain, and determination of a favorable collateral profile have become pivotal factors in consideration of the precision medicine of stroke decision-making. The conference convened over 50 invited faculty from around the world to connect on-site participants at a state-of-the-art facility with remote audiences in more than 22 countries and regions. The 2½-day program was structured into 40-min sessions devoted to key issues in translating the collaterome in acute stroke therapy across the globe. This unique forum of expertise emphasized the timely impact of collaterals on a monumental scale, encouraging maximal participation, rapid diffusion and added value of a diverse networking resource. The meeting format established a model geographical framework and innovative videoconferencing platform for future scientific conferences.

  7. Ash from huge Australian bushfires in 2009 circled the globe

    2011-06-01

    On 7 February 2009, record high temperatures, low rainfall and humidity, and fast blowing winds caused sparks in the bush near the Australian city of Melbourne to ignite much of the southeastern region of the state of Victoria. In just a few days, more than 4500 square kilometers had burned and 173 people had died in what has been called the worst natural disaster in Australian history. The fires released so much smoke that daytime on 7 February was plunged into darkness in Melbourne. Indeed, soot particles and other aerosols are known to scatter and absorb solar radiation. However, airborne particles released by fires are typically thought to remain in the atmosphere close to their sources. In fact, climate models pay little attention to the scattering and absorbing effects of fire-borne aerosols because they are not believed to reach altitudes above 10 kilometers, in the stratosphere, where circulation patterns would distribute a plume of pollution around the globe, possibly leading to global cooling effects. Ash from volcanic plumes has long been considered the sole method by which aerosols and gases could be injected into the stratosphere from the Earth's surface. However, Australia's bushfires of 2009 showed otherwise. (Journal of Geophysical Research-Atmospheres, doi:10.1029/2010JD015162, 2011)

    The global health crisis posed by vector-borne diseases is so great in scope that it is clearly insurmountable without the active help of tens-or hundreds- of thousands of individuals, working to identify and eradicate risk in communities around the world. Mobile devices equipped with data collection capabilities and visualization opportunities are lowering the barrier for participation in data collection efforts. The GLOBE Observer Mosquito Habitat Mapper (MHM) provides citizen scientists with an easy to use mobile platform to identify and locate mosquito breeding sites in their community. The app also supports the identification of vector taxa in the larvae development phase via a built-in key, which provides important information for scientists and public health officials tracking the rate of range expansion of invasive vector species and associated health threats. GO Mosquito is actively working with other citizen scientist programs across the world to ensure interoperability of data through standardization of metadata fields specific to vector monitoring, and through the development of APIs that allow for data exchange and shared data display through a UN-sponsored proof of concept project, Global Mosquito Alert. Avenues of application for mosquito vector data-both directly, by public health entities, and by modelers who employ remotely sensed environmental data to project mosquito population dynamics and epidemic disease will be featured.

    Ocular scintigraphy can now be carried out with several tracers: 131 I diiodofluorescein and sup(99m)Tc, hypervascularisation indicators; 131 I iodinated chloroquine, melanoma selective. The detector used is an Anger scintillation camera coupled to a multiparameter analysis chain or a computer. The ''pin-hole'' type collimator, which has a stenopaeic opening in front of each eye, is adaptable to any inter-pupil distance. The very simple scintigraphic procedure is described. The results, taken from two statistical studies on 198 and 80 patients respectively, concern the main types of eye disease encountered: malignant melanic tumours, other tumours, metastases, choroiditis, idiopathic detachments of the retina etc... The interpretation of the scintigrams and the problems involved are considered. Finally the main indications of the method are defined with emphasis on the possibilities of double scintigraphy, diiodofluorescein only showing up the hypervascularisation often associated with the tumour whereas iodinated chloroquine, when the result is positive, points to the presence of a malignant melanoma [fr

    Radioactive copper (67Cu++) was injected into the center of the vitreous body of rabbits. The relatively rapid initial loss of 67Cu from the vitreous was associated with its accumulation in intraocular tissues. At 24 hr, 20% of the injected 67Cu was found in the retina, representing the highest 67Cu concentration among all ocular tissues, and this high 67Cu concentration was maintained in this tissue throughout the 10-day observation period. Significant amounts of 67Cu were not detected in the aqueous humor at any time. About one-half of the injected 67Cu was lost from the whole globe in 5 days, but the remaining Cu was retained in the globe during the next 5 days. Eyes that received a large dose of CuSO4 in addition to the tracer showed decreased 67Cu activity in the retina and a slight increase in the aqueous humor. Endotoxin-induced ocular inflammation decreased the rate of 67Cu loss from the vitreous, reduced its accumulation by the retina, and increased 67Cu entry into the aqueous humor. It is concluded that 67Cu is retained in the vitreous and the globe due to its binding by, and/or uptake into, intraocular tissues, especially the retina. Cu does not effectively enter the anterior chamber from the vitreous, apparently due to its effective removal by the ciliary processes, thus ruling out the possibility of identifying the existence of Cu-containing intraocular foreign bodies in the posterior segment of the eye by analysis of Cu in the aqueous humor

    Here we present the evaluation findings for the first year of implementation of the `Mission Earth' Program.`Mission Earth' proposes the systematic embedding of GLOBE (Global Learning and Observations to Benefit the Environment) resources and NASA assets into the curricula of schools along the K-12 continuum, leveraging existing partnerships and networks. The main goal of the program is to create developmentally appropriate, vertically-integrated K-12 materials and activities,, supported by high quality professional development and ongoing support, engaging teachers from all grades. Its team consists of 5 geographically distributed universities and research institutions that have developed a curriculum progression following research-based best practices, have conducted the year's trainings for selected cohorts of teachers. The evaluation is a continuous process over the program's five year duration to examine implementation and opportunities for improvement. A broad set of data collection tools include a diagnostic component (needs assessment for teachers, capacity assessment for the school environment) and an assessment of implementation component (surveys for teachers and trainers, pre- and post tests for students, classroom observations, teacher interviews, portfolios). The tools used are validated instruments or ones modified to serve the program needs. The patterns emerging from the data provided information on: i) the quality of the intervention as to its design and content, ii) the alignment with the needs of the participants, iii) the implementation phase, iii) changes in the content knowledge of the students and their attitudes toward science, iv) changes in the facility of teachers to teach science in their classrooms after the professional development and materials provided, v) challenges and facilitators of implementation. Based on findings the program evaluation identifies additions/adjustments to be adopted in the following year.

    Citizen-science is a rewardingly inclusive way to bring awareness to the public on the disappearance of the starry night sky, its cause and solutions. Globe at Night (GaN) encourages citizen-scientists worldwide to record the brightness of the night sky. During ten-days per month of moonless evenings, children and adults match the appearance of a specified constellation with 7 star maps of progressively fainter stars found at www.globeatnight.org. They then submit their choice of star map in-situ with the “webapp” by smart device to add to a light pollution map worldwide. In the eleven years of the program, over 170,000 observations from 180 countries have been contributed to the campaign.The Globe at Night (open) database is a source of research projects, even with other disciplines. For example, students conducted research to understand the lesser long-nosed bats’ avoidance of city center at night. On-the-fly mapping enables citizen-scientists to see contributed observations immediately. The 12 campaigns per year offer 4 ways of taking measurements. The online app for data submission is in 28 languages. STEM activities for young children and problem-based learning activities for older students were created to experience real-life scenarios: role-playing sea turtles hatching (misdirected by lights on shore) or analyzing an ISS image of Houston to estimate the wasted energy, cost and carbon footprint. In-situ and on-line workshops have been given on using GaN in all its capacities, as well as for the activities. Our Facebook page exists to encourage dialogue and bring cutting edge news. To entice interest, we had monthly newsletters and serial podcasts starring the Dark Skies Crusader. GaN has been part of special campaigns like with the National Park Service, the National Geographic BioBlitz and Tucson in 2011. Partnerships also include SciStarter (working with participants), Fieldscope (working with data analysis), and STARS4ALL (working with other light

    The GLOBE Program, an international science and education program, encourages students from around the world to participate in authentic scientific research of the Earth system. Students use scientific protocols to explore their local environments, compare their findings with other GLOBE schools both in the U.S. and in other participating countries, and then share their findings via the GLOBE.gov website. In order to facilitate this scientific communication, GLOBE held an international virtual science fair in 2016. The science fair included 105 research projects submitted from GLOBE students in various countries, 37 mentoring scientists, and 24 judges. Mentors and judges were members of the GLOBE International STEM Professionals Network and located around the world. On a national level, NSF funded six face-to-face U.S. regional student research symposia where 164 students presented 67 research projects to scientists for review. The 1.5 day events included student activities, teacher professional development, tours of NASA centers, and opportunities for students to engage with scientists to discover both traditional and non-traditional STEM career pathways. To support teachers, the leadership team offered and archived webinars on science practices; from field investigation basics to creating a poster and GLOBE partners provided guidance along the way. This presentation will include the framework for the regional and international science symposia , the scoring rubrics and evaluation, recruitment of judges and mentors, and lessons learned.

    Cubomedusae have a total of 24 eyes of four morphologically different types. Two of these eye types are camera-type eyes (upper and lower lens-eye), while the other two eye types are simpler pigment pit eyes (pit and slit eye). Here, we give a description of the visual system of the box jellyfish...... those in the previously investigated species Tripedalia cystophora. In the lower lens-eye of C. bronzie, blur circles subtend 20 and 52° for closed and open pupil, respectively, effectively removing all but the coarsest structures of the image. Histology reveals that the retina of the lower lens...

    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.

  17. Global Warming and the Arctic in 3D: A Virtual Globe for Outreach

    2006-12-01

    Virtual Globes provide a new way to capture and inform the public's interest in environmental change. As an example, a recent Google Earth presentation conveyed 'key findings' from the Arctic Climate Impact Assessment (ACIA, 2004) to middle school students during the 2006 INSTAAR/NSIDC Open House at the University of Colorado. The 20-minute demonstration to 180 eighth graders began with an introduction and a view of the Arctic from space, zooming into the North American Arctic, then to a placemark for the first key finding, 'Arctic climate is now warming rapidly and much larger changes are projected'. An embedded link then opened a custom web page, with brief explanatory text, along with an ACIA graphic illustrating the rise in Arctic temperature, global CO2 concentrations, and carbon emissions for the last millennium. The demo continued with an interactive tour of other key findings (Reduced Sea Ice, Changes for Animals, Melting Glaciers, Coastal Erosion, Changes in Vegetation, Melting Permafrost, and others). Each placemark was located somewhat arbitrarily (which may be a concern for some audiences), but the points represented the messages in a geographic sense and enabled a smooth visual tour of the northern latitudes. Each placemark was linked to custom web pages with photos and concise take-home messages. The demo ended with navigation to Colorado, then Boulder, then the middle school that the students attended, all the while speaking to implications as they live their lives locally. The demo piqued the students' curiosity, and in this way better conveyed important messages about the Arctic and climate change. The use of geospatial visualizations for outreach and education appears to be in its infancy, with much potential.

    The objective of the study was to delineate clinical characteristics, surgical interventions, anatomic and visual outcomes of ruptured eye balls after trauma, and establish the prognostic indicators, which can assist clinicians in making correct surgical decisions during globe exploration for ruptured eyes. The study design used was a multicentre prospective cohort study, including six university-affiliated tertiary hospitals. We selected 242 cases of ruptured globe from the Eye Injury Vitrectomy Study database, until 31 December 2012. All selected cases underwent vitreoretinal surgery, enucleation or evisceration, and were followed up for at least 6 months. Age, visual acuity (VA) after injury, ocular trauma zone, time to surgery, corneal laceration, scleral wound, extrusion of iris or lens, ciliary body damage, intraocular haemorrhage, retinal detachment or defect, proliferative vitreoretinopathy (PVR) and choroidal damage were the predisposing factors evaluated by logistic regression models. We compared the pre-surgical indicators between cases of anatomically restored eyes with VA of 4/200 or better, or eyes with initial no light perception restored light perception or better, and cases of VA worse than 4/200, silicone oil-sustained eyes, phthisis or enucleation. Nearly 40% of cases with ruptured globe were anatomically restored through vitreoretinal surgery. The closed-funnel retinal detachment or extensive retinal loss (odds ratio [OR] = 3.38, P = 0.026), PVR-C (OR = 3.45, P = 0.008), and choroidal damage (OR = 4.20, P = 0.004) were correlated with poor outcomes. The closed-funnel retinal detachment or extensive retinal loss, PVR-C, and choroidal damage are the risk factors for unfavourable outcomes in globe ruptures. © 2015 Royal Australian and New Zealand College of Ophthalmologists.

    The Queens College GLOBE NY Metro Partnership was created to introduce GLOBE to more than 1.5 million students in southern NY State and provide continuing support for their teachers. In our first 18 months, we have trained 185 teachers from 82 schools and will triple these numbers this year. Teachers and administrators are attracted to GLOBE by its scientific rigor, the authentic research it offers students, and its fit with NYS standards. They are also eager to interact with our science faculty. Early difficulties included problems with the "standard" 5-day GLOBE training format and misconceptions that protocols are not suitable for urban settings and that preparing for the NYS Regents exams leaves no room for GLOBE. We held information meetings for school districts and for Queens high schools before our first workshop. These identified the most committed schools, energetic teachers, and potential implementation problems. Creative participants at these meetings countered the misconceptions and suggested solutions to the problems better than any outsider could, and generated an atmosphere leading to nearly 100% recruitment. The following stratagems have worked well: a close working relationship with the NYC Dept of Education, BOCES, and other environmental educators; affiliations with government agencies and community environmental groups; two bribes (giving a GLOBE instrument kit and GPS unit to each school that we train and awarding graduate or professional development credits for GLOBE training); a user-friendly training format (an initial 3-day workshop followed by two optional days for hydrology and land use); lending seldom-used items (e.g. soil auger) when needed; building a sense of GLOBE community with a graduation "ceremony", local website (www.qc.edu/qcglobe) and newsletter, phone and email helplines, and annual pedagogy and student research conferences. We also urge that three teachers be trained from each school in order to build local GLOBE support

  1. Measuring Magnetic Declination With Compass, GPS and Virtual Globes

    O'Brien, W. P.

    2006-12-01

    Using virtual globe (VG) imagery to determine geographic bearing and a compass to determine magnetic bearing yielded acceptable experimental magnetic declination values for large linear physical features at 13 sites in the western continental United States. The geographic bearing of each feature was determined from measurements involving the latitude/longitude coordinate system associated with the VG image (from World Wind or Google Earth). The corresponding magnetic bearing was measured on the ground at the feature with a hand-bearing compass calibrated in 1-degree subdivisions. A sequence of GPS trackpoints, recorded while traveling along the feature either in an automobile or on foot, unambiguously identified the pertinent portion of the feature (a straight segment of a road, for example) when plotted on the VG image. For each physical feature located on a VG image, its geographic bearing was determined directly using on-screen measurement tools available with the VG program or by hand using ruler/protractor methods with printed copies of the VG image. An independent (no use of VG) geographic bearing was also extracted from the slope of a straight-line fit to a latitude/longitude plot of each feature's GPS coordinates, a value that was the same (to within the inherent uncertainty of the data) as the VG-determined bearing, thus validating this procedure for finding geographic bearings. Differences between the VG bearings and the magnetic bearings yielded experimental magnetic declination values within one degree (8 within 0.5 degree) of expected values. From the point of view of physics and geophysics pedagogy, this project affords students a simple magnetism/geodesy field experiment requiring only a good compass and a GPS receiver with memory and a data port. The novel and straightforward data analysis with VG software yields reliable experimental values for an important abstract geophysical quantity, magnetic declination. Just as the compass has long provided

    Although serial killings are relatively rare, they can be the cause of a great deal of anxiety while the killer remains at-large. Despite the fact that the motivations for serial killings are typically quite complex, the psychological analysis of a serial killer can provide valuable insight into how and why certain individuals become serial killers. Such knowledge may be instrumental in preventing future serial killings or in solving ongoing cases. In certain serial killings, the various incidents have a variety of similar features. Identification of similarities between separate homicidal incidents is necessary to recognize that a serial killer may be actively killing. In this report, the authors present a group of serial killings involving three prostitutes who were shot to death over a 3-month period. Scene and autopsy findings, including the unusual finding of postmortem enucleation of the eyes, led investigators to recognize the serial nature of the homicides. © 2015 American Academy of Forensic Sciences.

  3. Zoonotic helminths affecting the human eye

    Science.gov (United States)

    2011-01-01

    Nowaday, zoonoses are an important cause of human parasitic diseases worldwide and a major threat to the socio-economic development, mainly in developing countries. Importantly, zoonotic helminths that affect human eyes (HIE) may cause blindness with severe socio-economic consequences to human communities. These infections include nematodes, cestodes and trematodes, which may be transmitted by vectors (dirofilariasis, onchocerciasis, thelaziasis), food consumption (sparganosis, trichinellosis) and those acquired indirectly from the environment (ascariasis, echinococcosis, fascioliasis). Adult and/or larval stages of HIE may localize into human ocular tissues externally (i.e., lachrymal glands, eyelids, conjunctival sacs) or into the ocular globe (i.e., intravitreous retina, anterior and or posterior chamber) causing symptoms due to the parasitic localization in the eyes or to the immune reaction they elicit in the host. Unfortunately, data on HIE are scant and mostly limited to case reports from different countries. The biology and epidemiology of the most frequently reported HIE are discussed as well as clinical description of the diseases, diagnostic considerations and video clips on their presentation and surgical treatment.

    The Global Learning and Observations to Benefit the Environment (GLOBE) Program is an international science and education program that provides students and the public worldwide with the opportunity to participate in data collection and the scientific process, and contribute meaningfully to our understanding of the Earth system and global environment. For more than 20 years, GLOBE-trained teachers have been leading environmental data collection and student research in the classroom. In 2016, GLOBE expanded to invite data collection from citizen scientists of all ages through a simple smart phone app. The app makes it possible for students to take GLOBE data (environmental observations) outside of school with their families. It enables a museum, park, youth organization, or other informal institution to provide a simple take-home activity that will keep patrons engaged in environmental science from home. This presentation will provide a demonstration of the app and will provide examples of its use in informal settings.

    Penetration of a bicycle brake handle into the orbit is a rare and serious type of trauma. Globe subluxation due to such trauma has not been previously reported. A 10-year-old girl presented after falling from a bicycle, which resulted in the handbrake penetrating her right upper eyelid. On examination, the globe was subluxated anteriorly, there was no light perception, and the pupilla was fixed and dilated. Radiologic studies revealed orbitonasal fractures, hemorrhage, emphysema in the orbit and cranium, and rupture of the extraocular muscles. The globe was replaced into the orbit with the help of lateral cantholysis and orbital septotomy. During 22 months of follow-up, the globe remained intact, but total loss of vision, blepharoptosis, and extraocular motility restriction persisted. This case and previous reports show that bicycle brake handles can cause severe, penetrating orbital and cerebral traumas that can result in vision loss or fatality. Brake handles should be designed to protect bicyclists from such injuries.

    Social Media is now a ubiquitous way for individuals, corporations, governments and communities to communicate. However, the same does not hold quite as true for the science community as many science educators, thought leaders and science programs are either reluctant or unable to build and cultivate a meaningful social media strategy. This presentation will show how The GLOBE Program uses social media to disseminate messages, build a meaningful and engaged following and grow a brand on an international scale using a proprietary Inside-Out strategy that leverages social media platforms such as Facebook, LinkedIn, Twitter, YouTube and Blogs to significantly increase influencers on a worldwide scale. In addition, this poster presentation will be interactive, so viewers will be able to touch and feel the social experience. Moreover, GLOBE representatives will be on hand to talk viewers through how they can implement a social media strategy that will allow them to turn their content into meaningful conversation. About The GLOBE Program: GLOBE is a science and education program that connects a network of students, teachers and scientists from around the world to better understand, sustain and improve Earth's environment at local, regional and global scales. By engaging students in hands-on learning of Earth system science, GLOBE is an innovative way for teachers to get students of all ages excited about scientific discovery locally and globally. To date, more than 23 million measurements have been contributed to the GLOBE database, creating meaningful, standardized, global research-quality data sets that can be used in support of student and professional scientific research. Since beginning operations in 1995, over 58,000 trained teachers and 1.5 million students in 112 countries have participated in GLOBE.

    2009-03-01

    Full Text Available Abstract Background The leaves of globe artichoke and cultivated cardoon (Cynara cardunculus L. have significant pharmaceutical properties, which mainly result from their high content of polyphenolic compounds such as monocaffeoylquinic and dicaffeoylquinic acid (DCQ, and a range of flavonoid compounds. Results Hydroxycinnamoyl-CoA:quinate hydroxycinnamoyltransferase (HQT encoding genes have been isolated from both globe artichoke and cultivated cardoon (GenBank accessions DQ915589 and DQ915590, respectively using CODEHOP and PCR-RACE. A phylogenetic analysis revealed that their sequences belong to one of the major acyltransferase groups (anthranilate N-hydroxycinnamoyl/benzoyltransferase. The heterologous expression of globe artichoke HQT in E. coli showed that this enzyme can catalyze the esterification of quinic acid with caffeoyl-CoA or p-coumaroyl-CoA to generate, respectively, chlorogenic acid (CGA and p-coumaroyl quinate. Real time PCR experiments demonstrated an increase in the expression level of HQT in UV-C treated leaves, and established a correlation between the synthesis of phenolic acids and protection against damage due to abiotic stress. The HQT gene, together with a gene encoding hydroxycinnamoyl-CoA:shikimate/quinate hydroxycinnamoyltransferase (HCT previously isolated from globe artichoke, have been incorporated within the developing globe artichoke linkage maps. Conclusion A novel acyltransferase involved in the biosynthesis of CGA in globe artichoke has been isolated, characterized and mapped. This is a good basis for our effort to understand the genetic basis of phenylpropanoid (PP biosynthesis in C. cardunculus.

  17. Red eye: Rule out Ophthalmomyiasis too

    Directory of Open Access Journals (Sweden)

    Pankaj Choudhary

    2013-01-01

    Full Text Available Ophthalmomyiasis is the infestation of human eye by the larvae of certain flies. Sheep botfly commonly manifests as Ophthalmomyiasis externa when there is conjunctival involvement or rarely as Opthalmomyiasis interna when there is larval penetration into the eyeball. It appears to be more common than what has been indicated by previously published reports. We present a report of seven cases of Ophthalmomyiasis by Oestrus ovis, from central India who presented with features of conjunctivitis varying between mild to severe. The larvae were seen in bulbar and palpebral conjunctiva and also entangled in lashes with discharge. Since the larvae are photophobic, it is prudent to look for them in the fornices and also in discharge. Prompt removal of the larvae from the conjunctiva helps in relieving the symptoms and also prevents serious complications. Taxonomic identification of the species is important to estimate the risk of globe penetration by the larvae.

  18. Dacitic ash-flow sheet near Superior and Globe, Arizona

    Science.gov (United States)

    Peterson, Donald W.

    1961-01-01

    Remnants of a dacitic ash-flow sheet near Globe, Miama, and Superia, Arizona cover about 100 square miles; before erosion the area covered by the sheet was at least 400 square miles and perhaps as much as 1,500 square miles. Its maximum thickness is about 2,000 feet, its average thickness is about 500 feet, and its original volume was at least 40 cubic miles. It was erupted on an eroded surface with considerable relief. The main part of the deposit was thought by early workers to be a lava flow. Even after the distinctive character of welded tuffs and related rocks was discovered, the nature and origin of this deposit remained dubious because textures did not correspond to those in other welded tuff bodies. Yet a lava flow as silicic as this dacite would be viscous instead of spreading out as an extensive sheet. The purpose of this investigation has been to study the deposit, resolve the inconsistencies, and deduce its origin and history. Five stratigraphic zones are distinguished according to differences in the groundmass. From bottom to top the zones are basal tuff, vitrophyre, brown zone, gray zone, and white zone. The three upper zones are distinguished by colors on fresh surfaces, for each weathers to a similar shade of light reddish brown. Nonwelded basal tuff grades upward into the vitrophyre, which is a highly welded tuff. The brown and gray zones consist of highly welded tuff with a lithoidal groundmass. Degree of welding decreases progressively upward through the gray and the white zones, and the upper white zone is nonwelded. Textures are clearly outlined in the lower part of the brown zone, but upward they become more diffuse because of increasing devitrification. In the white zone, original textures are essentially obliterated, and the groundmass consists of spherulites and microcrystalline intergrowths. The chief groundmass minerals are cristobalite and sanidine, with lesser quartz and plagioclase. Phenocrysts comprise about 40 percent of the rock

    2017-01-01

    Full Text Available Aim: The aim of this study is to describe treatment outcomes and complications of selective intra-arterial chemotherapy (IAC for intraocular retinoblastoma (RB. Materials and Methods: A retrospective, interventional series of 10 eyes with RB which underwent IAC using melphalan (5 mg/7.5 mg and topotecan (1 mg, or melphalan (5 mg/7.5 mg alone. Treatment outcomes were evaluated in terms of tumor control, vitreous seeds (VS and subretinal seeds (SRS control, and globe salvage rates. Results: Ten eyes of 10 patients underwent 38 IAC sessions (mean = 3.8; median = 4; range = 3–5 sessions. Following IAC, complete regression of main tumor was seen in 9 eyes (90% and partial regression in 1 (10%. All four eyes with SRS showed complete regression (100%. Of 5 eyes with VS, 3 eyes (60% showed complete regression, 1 eye (20% showed relapse, while 1 eye (20% showed no response. Globe salvage was achieved in 8 of 10 eyes (80%. Complications included transient ophthalmic artery narrowing (n = 2, branched retinal vein occlusion (n = 1, forehead skin pigmentation (n = 1, and vitreous hemorrhage (n = 2. There was no case of stroke, hemiplegia, metastasis, or death. Transient hematological changes included relative pancytopenia (n = 4, relative leukopenia (n = 5, and relative thrombocytopenia (n = 4. Mean follow-up was 26 months (median = 28, range = 13–36 from the initiation of first IAC. Conclusions: IAC is an effective therapy for globe preservation in eyes with intraocular RB, in the setting of a developing country like India. Larger studies with longer follow-up are required to validate these results.

    2017-06-01

    The Tobii Eyex Controller is a new low-cost binocular eye tracker marketed for integration in gaming and consumer applications. The manufacturers claim that the system was conceived for natural eye gaze interaction, does not require continuous recalibration, and allows moderate head movements. The Controller is provided with a SDK to foster the development of new eye tracking applications. We review the characteristics of the device for its possible use in scientific research. We develop and evaluate an open source Matlab Toolkit that can be employed to interface with the EyeX device for gaze recording in behavioral experiments. The Toolkit provides calibration procedures tailored to both binocular and monocular experiments, as well as procedures to evaluate other eye tracking devices. The observed performance of the EyeX (i.e. accuracy < 0.6°, precision < 0.25°, latency < 50 ms and sampling frequency ≈55 Hz), is sufficient for some classes of research application. The device can be successfully employed to measure fixation parameters, saccadic, smooth pursuit and vergence eye movements. However, the relatively low sampling rate and moderate precision limit the suitability of the EyeX for monitoring micro-saccadic eye movements or for real-time gaze-contingent stimulus control. For these applications, research grade, high-cost eye tracking technology may still be necessary. Therefore, despite its limitations with respect to high-end devices, the EyeX has the potential to further the dissemination of eye tracking technology to a broad audience, and could be a valuable asset in consumer and gaming applications as well as a subset of basic and clinical research settings.

    Saito, A.; Tsugawa, T.

    2017-12-01

    Digital globe system is a powerful tool to make the audiences understand phenomena on the Earth and planets in intuitive way. Geo-cosmos of Miraikan, Japan uses 6-m spherical LED, and is one of the largest systems of digital globe. Science on a Sphere (SOS) by NOAA is a digital globe system that is most widely used in science museums around the world. These systems are so expensive that the usage of the digital globes is mainly limited to large-scale science museums. Dagik Earth is a digital globe project that promotes educational programs using digital globe with low cost. It aims to be used especially in classrooms. The cost for the digital globe of Dagik Earth is from several US dollars if PC and PC projector are available. It uses white spheres, such as balloons and balance balls, as the screen. The software is provided by the project with free of charge for the educational usage. The software runs on devices of Windows, Mac and iOS. There are English and Chinese language versions of the PC software besides Japanese version. The number of the registered users of Dagik Earth is about 1,400 in Japan. About 60% of them belongs to schools, 30% to universities and research institutes, and 8% to science museums. In schools, it is used in classes by teachers, and science activities by students. Several teachers have used the system for five years and more. In a students' activity, Dagik Earth contents on the typhoon, solar eclipse, and satellite launch were created and presented in a school festival. This is a good example of the usage of Dagik Earth for STEM education. In the presentation, the system and activity of Dagik Earth will be presented, and the future expansion of the project will be discussed.

    Results of planetary mapping are often shared openly for use in scientific research and mission planning. In its raw format, however, the data is not accessible to non-experts due to the difficulty in grasping the context and the intricate acquisition process. We present work on tailoring and integration of multiple data processing and visualization methods to interactively contextualize geospatial surface data of celestial bodies for use in science communication. As our approach handles dynamic data sources, streamed from online repositories, we are significantly shortening the time between discovery and dissemination of data and results. We describe the image acquisition pipeline, the pre-processing steps to derive a 2.5D terrain, and a chunked level-of-detail, out-of-core rendering approach to enable interactive exploration of global maps and high-resolution digital terrain models. The results are demonstrated for three different celestial bodies. The first case addresses high-resolution map data on the surface of Mars. A second case is showing dynamic processes, such as concurrent weather conditions on Earth that require temporal datasets. As a final example we use data from the New Horizons spacecraft which acquired images during a single flyby of Pluto. We visualize the acquisition process as well as the resulting surface data. Our work has been implemented in the OpenSpace software [8], which enables interactive presentations in a range of environments such as immersive dome theaters, interactive touch tables, and virtual reality headsets.

  14. Observations of El Niño impacts using in situ GLOBE protocols and satellite data

    Science.gov (United States)

    Srinivasan, M. M.; Destaerke, D.

    2015-12-01

    The El Niño phenomenon is a periodic ocean condition that occurs every two to ten years in the central and east-central equatorial Pacific Ocean. It alters the normal patterns of ocean circulation, surface temperature, and evaporation, causing noticeable and often severe changes in weather conditions in many areas of the world. El Niño is the warm phase of the El Niño Southern Oscillation (ENSO), and usually reaches its peak between December and February time period. El Niño and its worldwide consequences are studied by the school network of the GLOBE Program (www.globe.gov) which brings together students, teachers, and scientists in support of student research and validation of international Earth science research projects. Since the start of the GLOBE Program over 20 years ago, GLOBE classrooms utilize carefully developed daily, weekly, or seasonally protocols such as maximum, minimum and current temperatures, rainfall, soil moisture, and others, to measure changes in the environment. The data collected by the students is entered in an online GLOBE database. In addition to the student-contributed data, automated stations also collect and send measurements to the GLOBE database.Students compare their data with global data acquired by satellites to help validate the satellite data. With a potentially historic-level El Niño event thought to be on the horizon--possibly one of the strongest in 50 years—we will propose an emphasis on measurements from GLOBE schools that will support studies and satellite observations of El Niño. We plan to provide the schools with additional satellite data sets such as ocean temperature measurements from Advanced Very High Resolution Radiometer (AVHRR), sea surface elevation measurements from Jason-2 and 3 (after it launches), and others to be identified. We wish to address and support the following educational objectives: - Demonstrate how El Niño affects local precipitation and temperature across the globe, - Link teachers

    1999-01-01

    Comeal transplantation is the only method of combating the blindness due to corneal opacity caused by infections, malnutrition, trauma and hereditary diseases. Comeal blindness is more prevalent in the developing countries. The availability of the donor cornea, trained ophthalmic surgeons and microsurgery facilities are the key factors in restoring vision in-patients with comeal blindness. The eye bank organization is somewhat similar to that of blood bank. The eye bank should be located in a hospital or a medical centre in which a laboratory may be established for the evaluation and storage of donor tissue. The medical director (Ophthalmologist), technician, secretary and public relation officer are the persons who play an important role in the successful organization of eye bank. The function of the eye bank are procurement, assessment, processing, distribution of donor eyes/corneas, training of technicians/doctors, and conducting research related to storage of donor tissue and corneal transplantation. The necessary infrastructure required for the organization of an eye bank include separate accommodation area for the personnel and the laboratory, telephone, computer, refrigerator, laminar air flow hood. Slitlamp, specular microscope, storage media and equipment, instrument for enucleation of donor eyes, and a motor vehicle. The details of responsibilities of the staff of eye bank, source of donor eyes, suitability of donor material, procurement of the donor cornea, tissue assessment, storage and preservation, distribution of donor tissue, and limitation of eye bank will be discussed at the time of presentation

    2007-12-01

    Georeferenced aerial imagery facilitates and enhances Earth science investigations. The realized value of imagery as a tool is measured from the spatial, temporal and radiometric resolution of the imagery. Currently, there is an need for a system which facilitates the rapid acquisition and distribution of high-resolution aerial earth images of localized areas. The Pict'Earth group has developed an apparatus and software algorithms which facilitate such tasks. Hardware includes a small radio-controlled model airplane (RC UAV); Light smartphones with high resolution cameras (Nokia NSeries Devices); and a GPS connected to the smartphone via the bluetooth protocol, or GPS-equipped phone. Software includes python code which controls the functions of the smartphone and GPS to acquire data in-flight; Online Virtual Globe applications including Google Earth, AJAX/Web2.0 technologies and services; APIs and libraries for developers, all of which are based on open XML-based GIS data standards. This new process for acquisition and distribution of high-resolution aerial earth images includes the following stages: Perform Survey over area of interest (AOI) with the RC UAV (Mobile Liveprocessing). In real-time our software collects images from the smartphone camera and positional data (latitude, longitude, altitude and heading) from the GPS. The software then calculates the earth footprint (geoprint) of each image and creates KML files which incorporate the georeferenced images and tracks of UAV. Optionally, it is possible to send the data in- flight via SMS/MMS (text and multimedia messages), or cellular internet networks via FTP. In Post processing the images are filtered, transformed, and assembled into a orthorectified image mosaic. The final mosaic is then cut into tiles and uploaded as a user ready product to web servers in kml format for use in Virtual Globes and other GIS applications. The obtained images and resultant data have high spatial resolution, can be updated in

    Tan, Zhi-Zhong; Essam, J W; Wu, F Y

    2014-07-01

    We consider the problem of two-point resistance in an (m-1) × n resistor network embedded on a globe, a geometry topologically equivalent to an m × n cobweb with its boundary collapsed into one single point. We deduce a concise formula for the resistance between any two nodes on the globe using a method of direct summation pioneered by one of us [Z.-Z. Tan, L. Zhou, and J. H. Yang, J. Phys. A: Math. Theor. 46, 195202 (2013)]. This method is contrasted with the Laplacian matrix approach formulated also by one of us [F. Y. Wu, J. Phys. A: Math. Gen. 37, 6653 (2004)], which is difficult to apply to the geometry of a globe. Our analysis gives the result in the form of a single summation.

  20. Heavenly Networks. Celestial Maps and Globes in Circulation between Artisans, Mathematicians, and Noblemen in Renaissance Europe.

    Science.gov (United States)

    Gessner, Samuel

    2015-01-01

    The aim of this paper is to examine the iconography on a set of star charts by Albrecht Dürer (1515), and celestial globes by Caspar Vopel (1536) and Christoph Schissler (1575). The iconography on these instruments is conditioned by strong traditions which include not only the imagery on globes and planispheres (star charts), but also ancient literature about the constellations. Where this iconography departs from those traditions, the change had to do with humanism in the sixteenth century. This "humanistic" dimension is interwoven with other concerns that involve both "social" and "technical" motivations. The interplay of these three dimensions illustrates how the iconography on celestial charts and globes expresses some features of the shared knowledge and shared culture between artisans, mathematicians, and nobles in Renaissance Europe.

  1. The Significance of Ongoing Teacher Support in Earth Science Education Programs: Evidence from the GLOBE Program

    Science.gov (United States)

    Penuel, B.; Korbak, C.; Shear, L.

    2003-12-01

    The GLOBE program provides a rich context for examining issues concerning implementation of inquiry-oriented, scientist-driven educational programs, because the program has both a history of collecting evaluation data on implementation and mechanisms for capturing program activity as it occurs. In this paper, researchers from SRI International's evaluation team explore the different roles that regional partners play in preparing and supporting teachers to implement the GLOBE Program, an international inquiry-based Earth science education initiative that has trained over 14,000 teachers worldwide. GLOBE program evaluation results show the program can be effective in increasing students' inquiry skills, but that the program is also hard for teachers to implement (Means et al., 2001; Penuel et al., 2002). An analysis of GLOBE's regional partner organizations, which are tasked with preparing teachers to implement its data collection and reporting protocols with students, shows that some partners are more successful than others. This paper reports findings from a quantitative analysis of the relationship between data reporting and partner support activities and from case studies of two such regional partners focused on analyzing what makes them successful. The first analysis examined associations between partner training and support activities and data reporting. For this analysis, we used data from the GLOBE Student Data Archive matched with survey data collected from a large sample of GLOBE teachers as part of SRI's Year 5 evaluation of GLOBE. Our analyses point to the central importance of mentoring and material support to teachers. We found that incentives, mentoring, and other on-site support to teachers have a statistically significant association with higher data reporting levels. We also found that at present, teachers access these supports less often than they access listservs and e-mail communication with teachers after GLOBE training. As a follow-up to this

    Perry, R. B.; Hamner, W. M.

    2006-12-01

    OceanGLOBE is an outdoor environmental research and education program for upper elementary, middle and high school students, supplemented by online instructional materials that are available without charge to any educator. OceanGLOBE was piloted in 1995 with support from a National Science Foundation Teacher Enhancement project, "Leadership in Marine Science" (award no.ESI-9454413 to UCLA). Continuing support by a second NSF Teacher Enhancement project (award no. ESI-9819424 to UCLA) and by COSEE-West (NSF awards OCE-215506 to UCLA and OCE-0215497 to USC) has enabled OceanGLOBE to expand to a growing number of schools and to provide an increasingly robust collection of marine science instructional materials on its website, http://www.msc.ucla.edu/oceanglobe/ OceanGLOBE provides a mechanism for students to conduct inquiry-based, hands-on marine science research, providing experiences that anchor the national and state science content standards learned in the classroom. Students regularly collect environmental and biological data from a beach site over an extended period of time. In the classroom they organize, graph and analyze their data, which can lead to a variety of student-created science products. Beach research is supported by instructional marine science materials on the OceanGLOBE website. These online materials also can be used in the classroom independent of the field component. Annotated PowerPoint slide shows explain research protocols and provide marine science content. Field guides and photographs of marine organisms (with emphasis on the Southern California Bight) and a growing collection of classroom investigations (applicable to any ocean location) support the science content presented in the beach research program and slide shows. In summary, OceanGLOBE is a comprehensive learning package grounded in hands-on, outdoor marine science research project in which students are the principal investigators. By doing scientific work repetitively over an

  3. Engaging the Public in the Citizen Science GLOBE at Night Campaign

    2011-05-01

    The emphasis in the international star-hunting campaign, GLOBE at Night, is in bringing awareness to the public on issues of light pollution. Light pollution threatens not only observatory sites and our "right to starlight", but can affect energy consumption, wildlife and health. GLOBE at Night has successfully reached a few 100,000 citizen-scientists. What steps can be taken to improve it? To promote the campaign via popular social media, GLOBE at Night created Facebook and Twitter pages. To increase participation in the 2011 campaign, children and adults submitted their sky brightness measurements in real time with smart phones or tablets using the web application at www.globeatnight.org/webapp/. With smart phones and tablets, the location, date and time register automatically. For those without smart mobile devices, user-friendly tools on the GLOBE at Night report page were reconfigured to determine latitude and longitude more easily and accurately. To increase the robustness of the data, 2 new approaches were taken. GLOBE at Night prototyped an "Adopt a Street” program in Tucson. The aim was for people to adopt different major or semi-major streets and take measurements every mile or so for the length of the street. The grid of measurements would canvas the town, allowing for comparisons of light levels over time (hours, days, years) or search for dark sky oases or light polluted areas. The increase to 2 campaigns in 2011 re-enforces these studies. The intent is to offer the program year-round for seasonal studies. The data can also be used to compare with datasets on wildlife, health, and energy consumption. Recently, NOAO and the Arizona Game and Fish Department have started a project with GLOBE at Night data and bat telemetry to examine a dark skies corridor in Tucson where the endangered bats fly. In our presentation, results of our efforts are discussed.

  4. A study on the impact of the GLOBE program on students' attitudes regarding environmental issues

    Science.gov (United States)

    Manfready, Gary Martin

    A key objective in environmental curricula should be to instill responsible and concerned attitudes toward environmental issues. This can be accomplished through the application of innovative programs which emphasize the development of the affective domain of learning. The development of personal attitudes is one form of evidence that the affective domain is being addressed. This study was undertaken to determine the impact of the GLOBE program (Global Learning and Observation to Benefit the Environment) on the attitudes of students toward environmental issues. Three hundred and five middle and high school level students from four states were surveyed to determine their attitudes toward selected environmental statements. Results demonstrated that attitudes toward environmental issues of GLOBE students were significantly greater than non-GLOBE students. Additional analysis demonstrated that regardless of grade levels, gender, racial and ethnicity backgrounds, depth of GLOBE involvement, and degree of teachers' GLOBE experiences, GLOBE students display similar levels of attitudes toward environmental issues. Establishment of a reliable Likert scale measurement instrument was accomplished. Permission to use an existing survey was obtained. Additional items were added to increase validity. Establishment of reliability was accomplished through a Guttman split half analysis of the piloted instrument. Through the use of factor analysis, four categories or sub-groupings of attitudes were determined to exist. Reliability was established for the factors. These sub-groupings were identified as personal commitment to environmental protection, awareness of avenues for action, loci of control, and students' perception of teachers' abilities to present environmental topics. These categories were a part of the analysis of four hypotheses.

  6. The GLOBE Program in Alabama: A Mentoring Approach to State-wide Implementation

    Science.gov (United States)

    Cox, G. N.

    2003-12-01

    Established in 1997, the GLOBE in Alabama (GIA) partnership has trained more than 1,000 teachers in almost 500 schools - over 25% of the total number of K-12 schools in Alabama. Over those five years, GIA has strived to achieve recognition of GLOBE as the "glue" to Alabama's new education program, the Alabama Math, Science and Technology Initiative (AMSTI). In 2003, GIA trained over 370 AMSTI K-8 teachers at two AMSTI hub sites in north Alabama. As the AMSTI program grows with the addition of future hub sites (eleven are planned), GIA must ready itself to train thousands of AMSTI teachers during the two-week summer professional development institutes that are part of AMSTI. A key component of AMSTI is a mentoring program conducted by math and science specialists - classroom educators loaned to the AMSTI hub sites by the school systems each hub site serves. The AMSTI mentoring program mirrors the GIA mentoring model begun in 1999 that originally funded regional GLOBE master teachers to provide technical assistance, feedback, and coaching for other GLOBE teachers. In schools where GIA mentor teachers were working, nearly a 100% increase in GLOBE student data reporting was noted. The GIA mentors now work within the hub site framework to ensure implementation of GLOBE as an integrated part of AMSTI. With the continued support of the State of Alabama, GIA will establish a network of mentors who work with the AMSTI hub site specialists in providing support for all AMSTI teachers. GIA is administered by the National Space Science and Technology Center, a partnership between NASA and the State of Alabama's seven research universities. Operational funding for GIA has been provided by the University of Alabama in Huntsville's Earth System Science Center, the NASA Marshall Space Flight Center, the Alabama Space Grant Consortium, The Alabama Department of Economic and Community Affairs, the Alabama State Department of Education, and Legacy. GIA has been able to build on these

    GLOBE at Night is an international science event designed to observe and record the visible stars as a means of measuring light pollution in a given location. Increased and robust understanding of our environment requires learning opportunities that take place outside of the conventional K-12 classroom and beyond the confines of the school day. This hands-on learning activity extended the traditional classroom and school day through 11 nights last March, when 18,000 citizen-scientists made over 4,500 observations from 96 countries. Utilizing the international networking capabilities of The GLOBE Program, GLOBE at Night was designed to make data collection and input user-friendly. Citizen-scientists were able to participate in this global scientific campaign by submitting their observations through an online database, allowing for authentic worldwide research and analysis by participating scientists. The data collected is available online in a variety of formats for use by students, teachers and scientists worldwide to assess how the quality of the night sky varies around the world. Using the online analysis tools provided by ESRI, participants were able to compare the observed data with population density and nighttime lighting datasets (DMSP Earth at Night). This comparison allowed correlations between observed data patterns and commonly used indices of population density and energy usage. This session will share our results and demonstrate how students and scientists across the globe can explore and analyze the results of this exciting campaign. We will discuss how the project team planned and executed the project in such a way that non-astronomers were able to make valid and useful contributions. We will also discuss lessons learned and best practices based on the 2006 campaign. GLOBE at Night is a collaborative effort sponsored by The GLOBE Program, the National Optical Astronomy Observatory (NOAO), Centro de Apoyo a la Didactica de la Astronomia (CADIAS

    This rare case report describes the diagnosis and treatment of an isolated left-sided orbital floor fracture with a complete dislocation of the globe into the maxillary sinus and briefly discusses the indications of surgery and recovery for orbital floor fractures in general. Complete herniation of the globe through an orbital blow-out fracture is uncommon. However, the current case illustrates that such an occurrence should be in the differential diagnosis and should be considered, especially following high speed/impact injuries involving a foreign object. In these rare cases, surgical intervention is required.

    This research advances the hypothesis that cross-country variation in the historical incidence of eye disease has influenced the current global distribution of per capita income. The theory is that pervasive eye disease diminished the incentive to accumulate skills, thereby delaying the fertility...... transition and the take-off to sustained economic growth. In order to estimate the influence from eye disease incidence empirically, we draw on an important fact from the field of epidemiology: Exposure to solar ultraviolet B radiation (UVB-R) is an underlying determinant of several forms of eye disease...

  11. Inflammation in dry eye.

    Science.gov (United States)

    Stern, Michael E; Pflugfelder, Stephen C

    2004-04-01

    Dry eye is a condition of altered tear composition that results from a diseased or dysfunctional lacrimal functional unit. Evidence suggests that inflammation causes structural alterations and/or functional paralysis of the tear-secreting glands. Changes in tear composition resulting from lacrimal dysfunction, increased evaporation and/or poor clearance have pro-inflammatory effects on the ocular surface. This inflammation is responsible in part for the irritation symptoms, ocular surface epithelial disease, and altered corneal epithelial barrier function in dry eye. Anti-inflammatory therapies for dry eye target one or more of the inflammatory mediators/pathways that have been identified in dry eye.

  16. An ocular biomechanic model for dynamic simulation of different eye movements.

    Science.gov (United States)

    Iskander, J; Hossny, M; Nahavandi, S; Del Porto, L

    2018-04-11

    Simulating and analysing eye movement is useful for assessing visual system contribution to discomfort with respect to body movements, especially in virtual environments where simulation sickness might occur. It can also be used in the design of eye prosthesis or humanoid robot eye. In this paper, we present two biomechanic ocular models that are easily integrated into the available musculoskeletal models. The model was previously used to simulate eye-head coordination. The models are used to simulate and analyse eye movements. The proposed models are based on physiological and kinematic properties of the human eye. They incorporate an eye-globe, orbital suspension tissues and six muscles with their connective tissues (pulleys). Pulleys were incorporated in rectus and inferior oblique muscles. The two proposed models are the passive pulleys and the active pulleys models. Dynamic simulations of different eye movements, including fixation, saccade and smooth pursuit, are performed to validate both models. The resultant force-length curves of the models were similar to the experimental data. The simulation results show that the proposed models are suitable to generate eye movement simulations with results comparable to other musculoskeletal models. The maximum kinematic root mean square error (RMSE) is 5.68° and 4.35° for the passive and active pulley models, respectively. The analysis of the muscle forces showed realistic muscle activation with increased muscle synergy in the active pulley model. Copyright © 2018 Elsevier Ltd. All rights reserved.

  18. Short-term memory across eye blinks.

    Science.gov (United States)

    Irwin, David E

    2014-01-01

    The effect of eye blinks on short-term memory was examined in two experiments. On each trial, participants viewed an initial display of coloured, oriented lines, then after a retention interval they viewed a test display that was either identical or different by one feature. Participants kept their eyes open throughout the retention interval on some blocks of trials, whereas on others they made a single eye blink. Accuracy was measured as a function of the number of items in the display to determine the capacity of short-term memory on blink and no-blink trials. In separate blocks of trials participants were instructed to remember colour only, orientation only, or both colour and orientation. Eye blinks reduced short-term memory capacity by approximately 0.6-0.8 items for both feature and conjunction stimuli. A third, control, experiment showed that a button press during the retention interval had no effect on short-term memory capacity, indicating that the effect of an eye blink was not due to general motoric dual-task interference. Eye blinks might instead reduce short-term memory capacity by interfering with attention-based rehearsal processes.

  19. Lymphatics and Lymphangiogenesis in the Eye

    Directory of Open Access Journals (Sweden)

    Shintaro Nakao

    2012-01-01

    Full Text Available Lymphatic is a prerequisite for the maintenance of tissue fluid balance and immunity in the body. A body of evidence also shows that lymphangiogenesis plays important roles in the pathogenesis of diseases such as tumor metastasis and inflammation. The eye was thought to lack lymphatic vessels except for the conjunctiva; however, advances in the field, including the identification of lymphatic endothelial markers (e.g., LYVE-1 or podoplanin and lymphangiogenic factors (e.g., VEGF-C, have revealed the exsitence and possible roles of lymphatics and lymphangiogenesis in the eye. Recent studies have shown that corneal limbus, ciliary body, lacrimal gland, orbital meninges, and extraocular muscles contain lymphatic vessels and that the choroid might have a lymphatic-like system. There is no known lymphatic outflow from the eye. However, several lymphatic channels including uveolymphatic pathway might serve the ocular fluid homeostasis. Furthermore, lymphangiogenesis plays important roles in pathological conditions in the eye including corneal transplant rejection and ocular tumor progression. Yet, the role of lymphangiogenesis in most eye diseases, especially inflammatory disease or edema, remains unknown. A better understanding of lymphatic and lymphangiogenesis in the eye will open new therapeutic opportunities to prevent vision loss in ocular diseases.

  20. Complications of cataract surgery in eyes filled with silicone oil.

    2018-03-01

    The aim of the study was to evaluate complications of cataract surgery in eyes filled with silicone oil. This retrospective, noncomparative, consecutive case series analyzed medical files of patients with eyes filled with silicone oil undergoing cataract surgery. Phacoemulsification with posterior chamber intraocular lens implantation was conducted with or without concurrent silicone oil removal. In this study, 121 eyes of 120 patients were included. In 32 eyes (26.4%) with evident silicone oil microemulsification or silicone oil-associated open-angle glaucoma, silicone oil was removed prior to phacoemulsification through a pars plana incision and no cases of posterior capsular rupture occurred during the subsequent cataract surgery. In the remaining 89 eyes, phacoemulsification was performed with silicone oil in the vitreous cavity. In these eyes, the rate of posterior capsular rupture was 9/89 (10.1%) and the rate of silicone oil migration into the anterior chamber through an apparently intact posterior capsule was 5/89 (5.6%). In 94 eyes (77.7%), an intraocular lens was inserted into the capsular bag, in 3 eyes (2.5%) into the sulcus, and in 1 eye (0.8%) a transscleral suturing was performed. In this series, complications related to the silicone oil were not uncommon during cataract surgery. In the majority of patients without evident silicone oil microemulsification or silicone oil-associated open-angle glaucoma, cataract surgery and posterior chamber intraocular lens implantation were performed while leaving the silicone oil in place.

    Directory of Open Access Journals (Sweden)

    X. Zhai

    2012-08-01

    Full Text Available We propose to advance the scientific understanding and applications of geospatial data by coupling Sensor Web and Geoprocessing Services in Virtual Globes for higher-education teaching and research. The vision is the concept of "What You See is What You Get" geoprocessing, shortly known as WYSIWYG geoprocessing. Virtual Globes offer tremendous opportunities, such as providing a learning tool to help educational users and researchers digest global-scale geospatial information about the world, and acting as WYSIWYG platforms, where domain experts can see what their fingertips act in an interactive three-dimensional virtual environment. In the meantime, Sensor Web and Web Service technologies make a large amount of Earth observing sensors and geoprocessing functionalities easily accessible to educational users and researchers like their local resources. Coupling Sensor Web and geoprocessing Services in Virtual Globes will bring a virtual learning and research environment to the desktops of students and professors, empowering them with WYSIWYG geoprocessing capabilities. The implementation combines the visualization and communication power of Virtual Globes with the on-demand data collection and analysis functionalities of Sensor Web and geoprocessing services, to help students and researchers investigate various scientific problems in an environment with natural and intuitive user experiences. The work will contribute to the scientific and educational activities of geoinformatic communities in that they will have a platform that are easily accessible and help themselves perceive world space and perform live geoscientific processes.

  10. The Pale Blue Dot: Utilizing Real World Globes in High School and Undergraduate Oceanography Classrooms

    Science.gov (United States)

    Rogers, D. B.

    2017-12-01

    Geoscience classrooms have benefitted greatly from the use of interactive, dry-erasable globes to supplement instruction on topics that require three-dimensional visualization, such as seismic wave propagation and the large-scale movements of tectonic plates. Indeed, research by Bamford (2013) demonstrates that using three-dimensional visualization to illustrate complex processes enhances student comprehension. While some geoscience courses tend to bake-in lessons on visualization, other disciplines of earth science that require three-dimensional visualization, such as oceanography, tend to rely on students' prior spatial abilities. In addition to spatial intelligence, education on the three-dimensional structure of the ocean requires knowledge of the external processes govern the behavior of the ocean, as well as the vertical and lateral distribution of water properties around the globe. Presented here are two oceanographic activities that utilize RealWorldGlobes' dry-erase globes to supplement traditional oceanography lessons on thermohaline and surface ocean circulation. While simultaneously promoting basic plotting techniques, mathematical calculations, and unit conversions, these activities touch on the processes that govern global ocean circulation, the principles of radiocarbon dating, and the various patterns exhibited by surface ocean currents. These activities challenge students to recognize inherent patterns within their data and synthesize explanations for their occurrence. Spatial visualization and critical thinking are integral to any geoscience education, and the combination of these abilities with engaging hands-on activities has the potential to greatly enhance oceanography education in both secondary and postsecondary settings

  13. A VIRTUAL GLOBE-BASED MULTI-RESOLUTION TIN SURFACE MODELING AND VISUALIZETION METHOD

    Directory of Open Access Journals (Sweden)

    X. Zheng

    2016-06-01

    Full Text Available The integration and visualization of geospatial data on a virtual globe play an significant role in understanding and analysis of the Earth surface processes. However, the current virtual globes always sacrifice the accuracy to ensure the efficiency for global data processing and visualization, which devalue their functionality for scientific applications. In this article, we propose a high-accuracy multi-resolution TIN pyramid construction and visualization method for virtual globe. Firstly, we introduce the cartographic principles to formulize the level of detail (LOD generation so that the TIN model in each layer is controlled with a data quality standard. A maximum z-tolerance algorithm is then used to iteratively construct the multi-resolution TIN pyramid. Moreover, the extracted landscape features are incorporated into each-layer TIN, thus preserving the topological structure of terrain surface at different levels. In the proposed framework, a virtual node (VN-based approach is developed to seamlessly partition and discretize each triangulation layer into tiles, which can be organized and stored with a global quad-tree index. Finally, the real time out-of-core spherical terrain rendering is realized on a virtual globe system VirtualWorld1.0. The experimental results showed that the proposed method can achieve an high-fidelity terrain representation, while produce a high quality underlying data that satisfies the demand for scientific analysis.

    The genome organization of globe artichoke (Cynara cardunculus var. scolymus), unlike other species belonging to Asteraceae (=Compositae) family (i.e. sunflower, lettuce and chicory), remains largely unexplored. The species is highly heterozygous and suffers marked inbreeding depression when forced to self-fertilize. Thus a two-way pseudo-testcross represents the optimal strategy for linkage analysis. Here, we report linkage maps based on the progeny of a cross between globe artichoke (C. cardunculus var. scolymus) and cultivated cardoon (C. cardunculus var. altilis). The population was genotyped using a variety of PCR-based marker platforms, resulting in the identification of 708 testcross markers suitable for map construction. The male map consisted of 177 loci arranged in 17 major linkage groups, spanning 1,015.5 cM, while female map was built with 326 loci arranged into 20 major linkage groups, spanning 1,486.8 cM. The presence of 84 loci shared between these maps and those previously developed from a cross within globe artichoke allowed for map alignment and the definition of 17 homologous linkage groups, corresponding to the haploid number of the species. This will provide a favourable property for QTL scanning; furthermore, as 25 mapped markers (8%) correspond to coding regions, it has an additional value as functional map and might represent an important genetic tool for candidate gene studies in globe artichoke.

    Globe artichoke leaves are highly rich in phenolic acids, in particular chlorogenic acid and dicaffeoylquinic acids. The latter are of particular interest since they can exert a stronger antioxidant activity, due to the presence of two adjacent hydroxyl groups on each of their phenolic rings. Plant

    PURPOSE: To assess the effect of simultaneous measurement of the two eyes in Hertel exophthalmometry (i.e., when both readings are taken sequentially, without removing the instrument from the orbital rims) and to find out whether simultaneous measurement would influence the final reading of each eye. METHODS: In this prospective, comparative study, Hertel exophthalmometry was performed on 61 patients by two experienced observers. Only patients with no history of orbital disease were included. Three different measurements were performed on each patient by each observer. Initially, the right eye was measured separately, then the left eye was measured separately, and finally, both eyes were measured together. RESULTS: When the eyes were measured separately, in 30% of cases observers obtained equal readings in both eyes; in 47%, the difference between the two eyes was 1 mm; and in 23%, the difference was 2 mm or more. However, in simultaneous bilateral measurements, in 73% of cases, observers obtained equal readings in both eyes; in 24%, the difference between the two eyes was 1 mm; and only in 3% was the difference 2 mm or greater. Paired t tests showed that the mean difference between measurements of the two eyes was significantly smaller in simultaneous bilateral measurements (p <0.001). Interobserver variation was similar for measurements taken separately on each eye and for simultaneous bilateral measurements. CONCLUSIONS: When both eyes were measured simultaneously with the Hertel exophthalmometer, examiners were inclined to obtain similar readings in both eyes of patients with symmetrical-appearing eyes. The possible bias arising this way may reduce the reliability of Hertel exophthalmometer in relative exophthalmometry.

  3. The Use of the Nelder-Mead Method in Determining Projection Parameters for Globe Photographs

    Science.gov (United States)

    Gede, M.

    2009-04-01

    A photo of a terrestrial or celestial globe can be handled as a map. The only hard issue is its projection: the so-called Tilted Perspective Projection which, if the optical axis of the photo intersects the globe's centre, is simplified to the Vertical Near-Side Perspective Projection. When georeferencing such a photo, the exact parameters of the projections are also needed. These parameters depend on the position of the viewpoint of the camera. Several hundreds of globe photos had to be georeferenced during the Virtual Globes Museum project, which made necessary to automatize the calculation of the projection parameters. The author developed a program for this task which uses the Nelder-Mead Method in order to find the optimum parameters when a set of control points are given as input. The Nelder-Mead method is a numerical algorithm for minimizing a function in a many-dimensional space. The function in the present application is the average error of the control points calculated from the actual values of parameters. The parameters are the geographical coordinates of the projection centre, the image coordinates of the same point, the rotation of the projection, the height of the perspective point and the scale of the photo (calculated in pixels/km). The program reads the Global Mappers Ground Control Point (.GCP) file format as input and creates projection description files (.PRJ) for the same software. The initial values of the geographical coordinates of the projection centre are calculated as the average of the control points, while the other parameters are set to experimental values which represent the most common circumstances of taking a globe photograph. The algorithm runs until the change of the parameters sinks below a pre-defined limit. The minimum search can be refined by using the previous result parameter set as new initial values. This paper introduces the calculation mechanism and examples of the usage. Other possible other usages of the method are

    Citizen science allows individuals anywhere in the world to engage in science by collecting environmental variables. One of the longest running platforms for the collection of in situ variables is the GLOBE program, which is international in scope and encourages students and citizen scientists alike to collect in situ measurements. NASA's Soil Moisture Active Passive (SMAP) satellite mission, which has been acquiring global soil moisture measurements every 3 days of the top 5 cm of the soil since 2015, has partnered with the GLOBE program to engage students from around the world to collect in situ soil moisture and help validate SMAP measurements. The current GLOBE SMAP soil moisture protocol consists in collecting a soil sample, weighing, drying and weighing it again in order to determine the amount of water in the soil. Preparation and soil sample collection can take up to 20 minutes and drying can take up to 3 days. We have hence developed a soil moisture measurement device based on Arduino- microcontrollers along with off-the-shelf and homemade sensors that are accurate, robust, inexpensive and quick and easy to use so that they can be implemented by the GLOBE community and citizen scientists alike. In addition, we have developed a phone app, which interfaces with the Arduino, displays the soil moisture value and send the measurement to the GLOBE database. This talk will discuss building, calibration and validation of the soil moisture measuring device and assessing the quality of the measurements collected. This work was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under contract with the National Aeronautics and Space Administration.

  5. Proliferative Vitreoretinopathy after Eye Injuries: An Overexpression of Growth Factors and Cytokines Leading to a Retinal Keloid

    Francesco Morescalchi

    2013-01-01

    Full Text Available Eye injury is a significant disabling worldwide health problem. Proliferative Vitreoretinopathy (PVR is a common complication that develops in up to 40–60% of patients with an open-globe injury. Our knowledge about the pathogenesis of PVR has improved in the last decades. It seems that the introduction of immune cells into the vitreous, like in penetrating ocular trauma, triggers the production of growth factors and cytokines that come in contact with intra-retinal cells, like Müller cells and RPE cells. Growth factors and cytokines drive the cellular responses leading to PVR’s development. Knowledge of the pathobiological and pathophysiological mechanisms involved in posttraumatic PVR is increasing the possibilities of management, and it is hoped that in the future our treatment strategies will evolve, in particular adopting a multidrug approach, and become even more effective in vision recovery. This paper reviews the current literature and clinical trial data on the pathogenesis of PVR and its correlation with ocular trauma and describes the biochemical/molecular events that will be fundamental for the development of novel treatment strategies. This literature review included PubMed articles published from 1979 through 2013. Only studies written in English were included.

    Full Text Available BACKGROUND: Different strategies to search and detect prey may place specific demands on sensory modalities. We studied visual field configuration, degree of eye movement, and orbit orientation in three diurnal raptors belonging to the Accipitridae and Falconidae families. METHODOLOGY/PRINCIPAL FINDINGS: We used an ophthalmoscopic reflex technique and an integrated 3D digitizer system. We found inter-specific variation in visual field configuration and degree of eye movement, but not in orbit orientation. Red-tailed Hawks have relatively small binocular areas (∼33° and wide blind areas (∼82°, but intermediate degree of eye movement (∼5°, which underscores the importance of lateral vision rather than binocular vision to scan for distant prey in open areas. Cooper's Hawks' have relatively wide binocular fields (∼36°, small blind areas (∼60°, and high degree of eye movement (∼8°, which may increase visual coverage and enhance prey detection in closed habitats. Additionally, we found that Cooper's Hawks can visually inspect the items held in the tip of the bill, which may facilitate food handling. American Kestrels have intermediate-sized binocular and lateral areas that may be used in prey detection at different distances through stereopsis and motion parallax; whereas the low degree eye movement (∼1° may help stabilize the image when hovering above prey before an attack. CONCLUSIONS: We conclude that: (a there are between-species differences in visual field configuration in these diurnal raptors; (b these differences are consistent with prey searching strategies and degree of visual obstruction in the environment (e.g., open and closed habitats; (c variations in the degree of eye movement between species appear associated with foraging strategies; and (d the size of the binocular and blind areas in hawks can vary substantially due to eye movements. Inter-specific variation in visual fields and eye movements can influence

    2012-01-01

    Full Text Available The effectiveness of eye care service delivery is often dependant on how the different stakeholders are aligned. These stakeholders range from the ministries of health who have the capacity to grant government subsidies for eye care, down to the primary healthcare workers who can be enrolled to screen for basic eye diseases. Advocacy is a tool that can help service providers draw the attention of key stakeholders to a particular area of concern. By enlisting the support, endorsement and participation of a wider circle of players, advocacy can help to improve the penetration and effectiveness of the services provided. There are several factors in the external environmental that influence the eye care services - such as the availability of trained manpower, supply of eye care consumables, government rules and regulations. There are several instances where successful advocacy has helped to create an enabling environment for eye care service delivery. Providing eye care services in developing countries requires the support - either for direct patient care or for support services such as producing trained manpower or for research and dissemination. Such support, in the form of financial or other resources, can be garnered through advocacy.

    Magnetic resonance imaging of the eye usually includes T2-weighted images both for screening purposes and for characterization of melanoma. Conventional T2-weighted spin-echo (SE) imaging suffers both from long acquisition times and incomplete recovery of the virteous' signal. A fast SE sequence was therefore compared prospectively with conventional sequences in 29 consecutive patients with lesions of the eye. Fast SE images delineated melanoma and other lesions of the eye from vitreous better than conventional T2-weighted images. Image quality and lesion conspicuity were improved on the fast sequence. Whereas melanoma appeared hypointense to vitreous on both types of images, subretinal effusion was hypointense on fast images and hyperintense on conventional T2-weighted images. Ghosting of the globe, which, however, did not decrease diagnostic value, was more pronounced on fast images. Conventional T2-weighted images may be replaced by fast SE images in MR studies of the eye with a gain in lesion conspicuity and significant time saving. (orig.)

    The major part of the eye consists of water . Continuous movement of water and ions between the ocular compartments and to the systemic circulation is pivotal for many physiological functions in the eye. The movement of water facilitates removal of the many metabolic products of corneal-, ciliary...... pressure. In the retina, water is transported into the vitreous body and across the retinal pigment epithelium to regulate the extracellular environment and the hydration of the retina. Aquaporins (AQPs ) take part in the water transport throughout the eye....

    Citizen-science is a rewardingly inclusive way to bring awareness to the public on important issues like the disappearing starry night sky, its cause and solutions. Citizen-science can also provide meaningful, hands-on “science process” experiences for students. One program that does both is Globe at Night (www.globeatnight.org), an international campaign to raise public awareness of the impact of light pollution by having people measure night-sky brightness and submit observations via a “web app” on any smart device or computer. Additionally, 2 native mobile apps - Loss of the Night for iPhone & Android, and Dark Sky Meter for iPhone - support Globe at Night.Since 2006, more than 125,000 vetted measurements from 115 countries have been reported. For 2015 the campaign is offered as a 10-day observation window each month when the Moon is not up. To facilitate Globe at Night as an international project, the web app and other materials are in many languages. (See www.globeatnight.org/downloads.)Students and the general public can use the data to monitor levels of light pollution around the world, as well as understand light pollution’s effects on energy consumption, plants, wildlife, human health and our ability to enjoy a starry night sky. Projects have compared Globe at Night data with ground-truthing using meters for energy audits as well as with data on birds and bats, population density, satellite data and trends over time. Globe at Night tackles grand challenges and everyday problems. It provides resources for formal and informal educators to engage learners of all ages. It has 9 years of experience in best practices for data management, design, collection, visualization, interpretation, etc. It has externally evaluated its program, workshops, lesson plans and accompanying kit to explore reasons for participation, skills developed, impact of experiences and perceived outcomes. Three recent papers (Birriel et al. 2014; Kyba et al. 2013; 2015) verify the

    Citizen science has proliferated recently due to widespread use of the internet and mobile devices, but it has a long history (i.e., the Christmas Bird Count). Since the mid-1990s, the GLOBE Program has engaged participants at a global scale. Though initially focused on teachers and students in formal education settings, it quickly attracted interest from the public as well. In 2016, GLOBE formally launched an initiative to widely engage citizen scientists in its 117 countries through release of a mobile app called GLOBE Observer (GO). GO seeks to increase the number and distribution of participants by providing a simple, engaging - and fun - interface to collect and report data. Observations featured in the app are a carefully selected subset of 50+ GLOBE measurement protocols. They must leverage app features, require little to no equipment besides the mobile device, and have scientists or other stakeholders ready to use the data. The app is designed to minimize barriers to participation, but for those who want to do or know more GLOBE also offers on-line training to turn observers into community members with recognized certification in a protocol area. First released was a cloud observation protocol, supporting validation of a variety of Earth imaging sensors. Second was a mosquito habitat mapping protocol, poised to greatly increase the amount and distribution of local data to validate disease forecast models based on remotely sensed conditions, with additional focus on eliminating disease-carrying mosquito breeding sites. Next in development is a land cover protocol to obtain ground truth imagery for the Landsat science team. The app is also being leveraged for quick development of a short-term eclipse mini-app, to be used on August 21st only during the North American eclipse. This app is designed to make it easy for large numbers of people observing the eclipse, throughout North America, to take and record high time resolution observations of cloud cover and

    The focus of this case report is on the psychological reintegration process following the achievement of a highly challenging long-duration and solitary endeavor. The participant was a 29 year old male who successfully circumnavigated the globe during a 260 day solo sailing expedition. We assessed the psychological aftermath in terms of stability and change in personality characteristics and personal beliefs prior to, and at 180 and 360 days after the completion of the journey. Overall, the personality configuration reflected adaptive personality functioning. A belief in an internal locus of control was consistent throughout, as were perceptions of personal growth as a result of the circumnavigation experience. NEO PI-R Neuroticism, Extraversion, Openness, and Triarchic Psychopathy Measure (Tri-PM) Boldness scores remained stable. Positive personality change was reflected by an elevation in Conscientiousness; negative change by a decline in Agreeableness and an increase in Tri-PM Disinhibition. While overall the participant exhibited positive change as a result of his journey, there were also some negative aspects of the reintegration phase in regard to interactions with other persons. This latter change may be related to the effects of isolation from usual social contacts over an extended period. © 2015 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    . This ground-breaking book re-thinks and re-invests in the notion of authenticity as a surplus of experiential meaning and feeling that derives from what we do at/in places. In "Re-investing Authenticity - Tourism, Place and Emotions" international scholars representing a wide range of disciplines, examine...... contemporary performances of authenticity in travel and tourism practices: from cultural place branding to individual pilgrim performances; from intensified experiences of imaginary crime scenes to the rhetorical features of the encounter with the traumatic; and, from photography performing memories of place...

    Purpose There is a paucity of data on child abuse and the eye in West Africa. Therefore, a need exists to determine the causes and circumstances surrounding these occurrences and their effects on the eye and vision in a pediatric population. Methods A 3-year study of consecutive cases of ocular features that presented to an eye clinic following a history suggestive of child abuse along with any associated eye injury was carried out. Socio-demographic characteristics were obtained, as were the presenting and posttreatment visual acuity, and a full clinical eye examination was also done. Results Fifty-six children with 56 affected eyes were examined. The male to female ratio was 1.8 : 1; the mean age was 8.25 ± 3.5 years; and the subjects were predominately primary school children 30 (53.6%). The most common ocular disorders were conjunctiva hyperemia (46.4%), corneal abrasion/ulcer (25.4%), hyphema/uveitis (42.9%), retinal detachment (7.1%), sclera rupture (7.1%), and globe perforation (21.4%). The intraocular pressure was raised in 17.9% of participants. Presenting versus posttreatment visual acuities showed normal vision in four (7.1%) vs. eighteen (32.1%), visual impairment in 12 (21.4%) vs. six (10.7%), severe visual impairment in 20 (35.7%) vs. 12 (21.4%), and blindness in 12 (21.4%) vs. 14 (25%), p corporal punishment, accidents, and assaults. Legislation and laws need to be enacted to prevent negative psychosocial and economic impacts on the child, family and country as a whole. PMID:28367043

    , Danish Rural Eye Study (DRES). All DRES participants received a comprehensive general health examination preceding their eye examination, including measurement of best-corrected visual acuity (BCVA) for each eye, bilateral 45° retinal fundus photographs and further ophthalmological examination where...... indicated. RESULTS: Overall, 3826 of 3843 participants (99.6%) had bilateral visual acuity measurements. The overall frequency of VI (BCVA eye) was 0.4% (95% confidence interval, CI, 0.2-0.7%; n = 15) among all DRES participants, 0.6% (95% CI 0.3-1.0%; n = 15) among participants...... >50 years and 3.7% (95% CI 2.1-6.5%; n = 11) in participants >80 years. The primary causes of VI in the better-seeing eye were age-related macular degeneration (AMD) in 46.7% (7/15) and cataract in 26.7% (4/15). A total of 43.3% (n = 115) of participants >80 years were pseudophakic in one or both eyes...
