Aesthetic aspects of plant communities of ruderal urban sites in Szczecin

Synanthropization of plant cover, connected with urban development, contributes to the appearance of specialized ruderal plant communities, adapted to habitats exposed to human influence. A lot of published data have focused on urban flora, but the aesthetic aspect of perennial and temporary plant communities at urban sites has been frequently omitted. Currently the practical use of such plant communities is limited by the lack of descriptive information available. In this study great attention has been paid to variability of urban communities, defined by: aesthetic aspects, flowering period, and colour variability in flowering communities. In Szczecin, Artemisio-Tanacetetum vulgaris, Calamagrostietum epigeji, Dauco-Picridetum hieracioidis, and Rudbeckio-Solidaginetum have been recognized as especially decorative. They could be used to reduce the costs of establishing and maintaining urban green areas.

Significance of protection of the meadow and grassland communities for maintenance the floristic diversity in the area of the south-eastern Silesian Upland (Poland)

Variety of relief and geology of the south-eastern Silesian Upland results in richness and diversity of its vegetation. Wet meadows and xerothermic grasslands are one of its most valuable components. In their phytocoenoses many protected (27 in meadows and 22 in grasslands) and rare (25 and 34) species have been noted. Among them there are threatened species put on the "Red list of the vascular plants in Poland". A few species represent the mountain element. Some meadow and grassland phytocoenoses from the south-eastern part of the Silesian Upland are characterised by exceptionally high floristic richness. The Cirsietum rivularis patches have proved to be the richest among them. Large-scale cessation of usage caused that meadows and grasslands actually need urgent active protection here. This is the only chance of survival for many rare protected and threatened plants.

Protected plant species of forest, lakes and peatbogs in the Western Part of the Drawskie Lakeland

A floristic study of forest communities, lakes, and peatbogs of the western part of the Drawskie Lakeland was carried out in 2006-2008. The study revealed the presence of numerous valuable plant species. More than 400 floristic lists were compiled. Plant surveys were conducted with the aid of the ATPOL square grid system. To increase the accuracy of the surveys, the basic ATPOL squares (10x10 km) were additionally subdivided into smaller ones of 1x1 km. The area of study was found to support 416 plant species, including protected ones: 17 species strictly protected (e.g., Blechnum spicant, Dactylorhiza incarnata, Drosera rotundifolia, Lycopodium annotinum, Utricularia intermedia) and 12 under partial protection (e.g., Frangula alnus, Menyanthes trifoliata, Ononis spinosa, Ribes nigrum, Viburnum opulus). The list of protected plants contains one species (Lobelia dortmanna) included in the Polish Red Book of Plants.

Authors: Ellington J. Kent , Anderson Robert B. , Davis W. Hodges , Cohen Bruce E. , Jones Carroll P.
Published: May 2010

Background: Lesser toe deformities are frequent and bothersome conditions. Many options exist for the treatment of hammertoes and clawtoes. The purpose of this study was to review our experience with the use of an intramedullary fusion device. Materials and Methods: An IRB approved retrospective review was performed to identify 38 toes in 27 patients treated with the StayFuse™ (Nexa Orthopaedics) device with a mean followup of 31 months. The indications for surgery were primary deformity in 12 toes and recurrent deformities in 26 toes. Results: Union occurred in 23 of 38 (60.5%). The union rate was nine of 12 for primary procedures and 53.8% (14/26) for revisions. Coronal PIP alignment demonstrated no change in 33 of 38 cases (86.8%) and changed in five of 38 (13.2%). Sagittal PIP alignment demonstrated no change in 36 of 38 cases (94.7%), and changed in 2/38 (5.3%). Including nonunion, the overall complication rate was 55.3% (21/38) (15 nonunions; three hardware failures (two (bent) not requiring intervention and one (broke) leading to a rotational deformity requiring revision), one intraoperative fracture (without sequelae), one requiring MP surgery, and one requiring a larger implant. The index surgery for all three of the patients that required a second surgery was for a recurrent deformity. All three patients requiring a second surgery occurred in the nonunion group. Conclusion: The StayFuse™ intramedullary fusion device was efficacious in maintaining PIP alignment in the treatment of lesser toe deformities with a relatively low reoperation rate at mid-term followup.

Authors: Ibrahim Mahmoud I. , Donatelli Robert A. , Schmitz Christoph , Hellman Madeleine A. , Buxbaum Frederick
Published: May 2010

Background: Radial extracorporeal shock wave therapy (RSWT) has been previously demonstrated as an efficient treatment option for chronic plantar fasciitis (PF) when administered in three sessions. The present study tested the hypothesis that chronic PF can also be treated successfully with RSWT when only two treatment sessions are performed. Materials and Methods: A total of 50 patients with unilateral, chronic PF were randomly assigned to either RSWT ( n = 25) or placebo treatment ( n = 25). RSWT was applied in two sessions 1 week apart (2,000 impulses with energy flux density = 0.16 mJ/mm2 per session). Placebo treatment was performed with a clasp on the heel. Endpoints were changes in the Visual Analog Scale (VAS) score and the modified Roles & Maudsley (RM) score from baseline to 4 weeks, 12 weeks and 24 weeks followup. Results: Mean VAS scores were reduced after RSWT from 8.5 ± 0.3 (mean ± SEM) at baseline to 0.6 ± 1.5 at 4 weeks, 1.1 ± 0.3 at 12 weeks and 0.5 ± 0.1 at 24 weeks from baseline. Similar changes were found for mean RM scores from baseline after RSWT but were not observed after placebo treatment. Statistical analysis demonstrated that RSWT resulted in significantly reduced mean VAS scores and mean RM scores at all followup intervals compared to placebo treatment (each with p < 0.001). No serious adverse events of RSWT were observed. Conclusion: RSWT was successful in the treatment of chronic PF even when only two sessions with 2,000 impulses each were performed 1 week apart.

Authors: Noguchi Hideo , Ishii Yoshinori , Takeda Mitsuhiro , Hasegawa Atsushi , Monden Satoshi , Takagishi Kenji
Published: May 2010

Background: We treated 12 cases of posterior ankle bony impingement in 12 athletes arthroscopically, and examined the operating methods, findings, and postoperative physical therapy and overall results. Materials and Methods: The patients' average age was 21.4 years. The mean duration of postoperative followup was 33.8 months. A 2.7-mm, 30 degree arthroscope was inserted into the subtalar joint using posterolateral and accessory posterolateral portals. When the impinged fragment was visualized, it was carefully excised from the surrounding soft tissues. The operation was completed once the entire flexor hallucis longus tendon was seen. No cast immobilization was applied postoperatively, and physical therapy including limited weight bearing and range-of-motion exercises commenced within 24 hours after surgery. Beginning 3 weeks after surgery, the patients were permitted to gradually resume sports under the guidance of a physiotherapist. The AOFAS ankle-hindfoot score, the postoperative range of motion of the ankle and the time to recover were determined. Results: The average postoperative AOFAS ankle-hindfoot score improved from 68.0 to 98.3 points. The mean preoperative range of motion of the ankle joint was improved from 59.2 degree to 68.4 degree. The average period to return to sports was 5.9 weeks. All patients reached full activity within 13 weeks after surgery. The surgical time ranged from 40 minutes to over 2 hours and was affected by the impingement condition. Conclusion: Arthroscopic treatment for posterior ankle bony impingement syndrome was minimally invasive and suitable for athletes who desire an early return to sports activity.

Authors: Fukuda Tomiko , Haddad Steven L. , Ren Yupeng , Zhang Li-Qun
Published: May 2010

Background: There is limited literature available to assess the impact of talar component rotation on total ankle contact biomechanics. Materials and Methods: Six male cadaveric below-knee specimens were implanted with Agility® total ankles. The sequence of talar rotation for each specimen was randomized between: Neutral, 7.5 degrees internal and 7.5 degrees external rotation. Contact pressure was measured using Tekscan ankle sensors during sequential static axial loadings and 10 simulated dynamic strides under 650 N axial load. Results: The peak pressure (PP) increased for the internally (PPstatic = 7.0 ± 0.27 MPa (mean ± SD), p < 0.001; PPdynamic = 7.8 ± 0.22 MPa, p = 0.001) and externally rotated talar component positions (PPstatic = 6.2 ± 0.22 MPa, p = 0.011; PPdynamic = 7.6 ± 0.29 MPa, p = 0.004) as compared to neutral (PPstatic = 5.5 ± 0.13 MPa; PPdynamic = 6.3 ± 0.11 MPa). The contact area under 650 N load was reduced for both talar component internal (97.38 ± 17.7 mm2, p = 0.001) and external rotation (152.66 ± 16.8 mm2, p = 0.022) as compared to neutral (190.02 ± 13.8 mm2). There was a significant rotational torque for the malrotated talar components as compared to neutral, that increased with axial loading ( p = 0.044). Conclusion: Near the extremes of talar malrotation, there was a consistent change from a continuous tibiotalar contact area to a pattern of two-point contact; the orientation of which opposed the direction of talar component malrotation. Talar component malrotation resulted in: increased peak pressure, decreased contact area and increased rotational torque that resisted the malrotation. Clinical Relevance: Talar component malrotation may contribute to premature polyethylene wear as well as potential talar loosening secondary to the rotational torque generated as the geometry of the prosthesis attempts to seek congruency.

Published: May 2010

Background: Tibialis anterior tendon rupture is an uncommon injury that can cause significant functional deficit. Recent series have supported surgical reconstruction in younger, more active patients. We investigated our clinical outcomes of patients having undergone surgical management of tibialis anterior tendon ruptures. Materials and Methods: Fifteen tibialis anterior tendon ruptures in 14 patients were retrospectively reviewed after surgical management. Five had primary repair, while 10 had tendon transfers. Average age at time of surgery was 70.6 years with an average followup of 27.2 months. Patients were evaluated with American Orthopaedic Foot and Ankle Society (AOFAS) and SF-36 clinical outcome scores. Strength measurements utilizing a dynamometer and range of motion (ROM) were documented on the operative and non-operative ankles. Patient satisfaction surveys were performed. Results: Average postoperative AOFAS hindfoot score was 88.8 and SF-36 score was 76.4. There was a statistically significant difference in average dorsiflexion strength of 21.8 lbs/in2 on the operative side and 28.8 lbs/in2 on the non-operative limb, and in dorsi-flexion ROM of patients that received a gastrocnemius recession. There was no statistically significant difference between primary tendon repair versus tendon transfer groups nor plan-tarflexion strength or ROM among any group. Patient surveys revealed that seven patients were completely satisfied, six had minor reservations, and one had major reservations. There were no complications. Conclusion: This study supports the surgical repair or reconstruction of the tibialis anterior tendon ruptures to restore functional strength and ROM.

Authors: Chiodo Christopher P. , Hahne Jochen , Wilson Michael G. , Glowacki Julie
Published: May 2010

Background: Cancellous bone graft is frequently used during orthopedic procedures. While the iliac crest has traditionally been the most common donor site, the proximal tibia is an alternative donor site, especially for foot and ankle procedures. This study tested the null hypothesis that the histologic composition of iliac and tibial bone grafts is similar. Materials and Methods: Specimens from the iliac crest ( n = 10) and tibia ( n = 10) in excess of that needed for patients undergoing foot or ankle fusion were examined histologically. Iliac samples were taken from the anterior iliac crest. Tibial samples were harvested from the region of Gerdy's tubercle. Specimens were graded based on the percent of bone surfaces that opposed active hematopoietic marrow, with Grade I at 0%, through Grade VI at 81% to 100%. Differences between iliac and tibial grafts were evaluated with Fisher's Exact Test. Results: Iliac crest and tibial bone grafts both showed trabecular fragments with abundant osteocytes. All iliac grafts contained active hematopoietic marrow. In contrast, the medullary space of tibial grafts contained fat and little hematopoietic marrow. Nine iliac grafts were graded V or VI; whereas the ten tibial bone grafts were all graded I or II ( p = 0.0001). The difference in the numbers of samples in each group ranked as grade VI was also statistically significant ( p = 0.005). Conclusion: Iliac bone grafts contained active hematopoietic marrow, whereas quiescent medullary fat predominated in tibial grafts. Clinical Relevance: These findings raise questions about the cellular contributions of different sources of bone graft to bone healing.

Authors: Rein Susanne , Fabian Tobias , Zwipp Hans , Mittag-Bonsch Martina , Weindel Stefan
Published: May 2010

Background: The aim of this study was to examine the influence of age, body mass index (BMI) and leg dominance on the PRT, balance control and foot position sense. Materials and Methods: The proprioception of the ankle was investigated in 210 participants. All participants completed a questionnaire. The PRT was measured on a tilting platform. The position sense test was performed. Balance control was assessed with the Biodex Stability System (BSS), measuring the overall stability index (OSI) at the stable level 8 and the unstable level 2. Correlation analyses were performed between these data and age, BMI and leg dominance, using the Spearman-Rho coefficient with a two-sided significance level of p < 0.05. Results: Significant increases of the PRT and OSI in correlation to increased age and BMI were noted for both legs ( p < 0.05). No positive correlation to age, BMI or leg dominance could be demonstrated for the foot position sense test. The PRT of the right leg was always significantly faster than that of the left leg, irrespective of leg dominance ( p < 0.05). Surprisingly, individuals with a dominant right leg achieved better OSI scores in left single leg stance at the unstable level 2 ( p < 0.05). Conclusion: The PRT and the postural stability correlate with age and BMI, whereas the position sense test of the ankle does not. Furthermore, the PRT in right legs is always faster. This should be noted when functional ankle stability is evaluated in patients.

Published: May 2010

One year cross sectional study was undertaken in 50 patients with peritonsillar abscess to determine the treatment that was most effective in relieving the excruciating pain associated with the condition. The patients were divided into two treatment groups: intravenous antibiotic, and incision and drainage. The effect of treatment over was objectively assessed by serially measuring the distence between upper & lower incisor and by giving the patient water to drink at regular intervals to determine the point at which swallowing was pain-free. The improvement of the mean upper to lower incisor distance 15 minutes after the initial treatment was five per cent in the intravenous antibiotic group and 100 per cent in the incision and drainage group. None of the patients in the intravenous antibiotic group was able to swallow water two hours after the initial treatment. In the same time interval 23 patients (92 per cent) in the incision and drainage group were able to swallow water. The conclusion derived from this study is that incision and drainage is superior to intravenous antibiotic in relieving the pain associated with peritonsillar abscess.

A prospective study was carried out from 2001 to 2002 at Department of Otolaryngology and Head- Neck Surgery, BSMMU, DMCH, SSMC & Mitford Hospital, Dhaka. Data were collected from 45 patients with histologically diagnosed hypopharyngeal carcinoma on the following variables 1) sociodemographics, 2) clinical manifestations, 3) sub-sites of carcinoma, 4) clinical staging, 5) time of diagnosis, 6) associated risk factors, and 8) patients general performance status at presentation was determined by the Karnofsky scoring system. Results of this study showed that hypopharyngeal carcinoma affects fourth (60%) and fifth (26.7%) decade of life. It was found that male was highly predominant to develop hypopharyngeal carcinoma and ratio was 6:1. People with lower educational level and lower income group were found to be affected more by hypopharyngeal carcinoma. In this study the mean time elapsed from the appearance of the first symptom to the diagnosis of hypopharyngeal carcinoma was 4.11 months. This study found that the key symptom of hypopharyngeal carcinoma was dysphagia, pain, hoarseness and neck mass. 80 percent patient presented with palpable lymph node and all of them were in level II. Pyriform fossa was found to be the commonest site (80%) affected by carcinoma. In this series 75 percent patient presented in stage III and stage IV. There is strong relation between staging and diagnostic delay (p<0.05). In this study 86.7 percent patients had history of smoking. Smoking was found significantly associated with hypopharyngeal carcinoma (p<0.05). Betel nut chewing and tobacco chewing was found to be significant factors to develop hypopharyngeal carcinoma (p<0.05). This study showed that there was no patient with good oral health. Bad and average orodental hygiene was found in 44.4 and 55.6 percent respectively. Statistically bad oral hygiene was significantly related to hypopharyngeal carcinoma (p<0.05). Performance status of the patients at presentation was good and 77.8 percent of patients with hypopharyngeal carcinoma at diagnosis were capable of self-care.  DOI: 10.3329/bjo.v14i1.3276 Bangladesh J of Otorhinolaryngology 2008; 14(1) : 23-29

Transsphenoidal approach to sella is not a new approach. In the last 100 years it has gone numerous changing refinements from using headlight to microscope and more recently the sensitive endoscope. In this prospective study, all patients with pituitary tumor who underwent endonasal transsphenoidal pituitary surgery during the period of January 2006 to July 2009 in the department of neurosurgery, Dhaka Medical College Hospital and Islami Bank Central Hospital, Dhaka, Bangladesh were included. Among the 55 patients 36 cases were operated by combined endoscopic and microscopic techniques and 19 cases were operated by endoscope only. Total 73 procedures were done in 55 patients. Age range was 17 years to 70 years. Follow up period was 03 months to 42 months (mean 14.2 months) .Male: female was almost 1:1. Clinical features were pituitary apoplexy, pituitary apoplexy with 3rd/+6th cranial nerve palsy, headache, amenorrhea, loss of libido, galactorrhoea, gynecomastia, weight gain and psychosis. Visual impairment was in 35 cases. Functioning adenoma was 21 and non functioning adenoma was 34 cases. Among the functioning adenoma acromegaly was seen in 12 cases, gigantism in 01 case, prolactinoma in 05 cases, Cushing's disease 03 cases. Purely sellar tumor was 15, sellar & suprasellar 35 and sellar & parasellar 11 cases. Microscopic plus endoscopic techniques used in 54 procedures. Purely endoscopic procedures were 19. Complete removal of tumor in single stage was done in 33 cases. Complete removal with more than one stage surgery in 13 cases. In our initial cases of the series, we exposed the sella endonasally with endoscope then we used microscope for the rest of the surgery. In the later part of the series we gained experience and confidence for removal of pituitary tumor with an endoscope completely. The rate of diabetes insipidus occurred in 11(20%) cases and all are transient. Postoperative CSF leak was noted in 10(18%) cases. Patient with ocular palsy improved post operatively within 6 weeks. Among non functioning adenoma that were removed completely (30 cases) recurrence occurred in three cases. Eleven patients were stable in vision as preoperative. Other showed visual improvement to variable extents. Key words: Pituitary surgery; Endonasal; Transsphenoidal; Microsurgery; Endoscopic surgery.

Objective: To study the clinical, audiological and radiological characteristics along with the management outcome of chronic otitis media with effusion. Setting: Department of Otolaryngology & Head - Neck Surgery, Dhaka Shishu Hospital and Apollo Hospital's Dhaka, Bangladesh. Materials and Methods: This study included three hundred and thirty patients of chronic Otitis media with effusion that have been treated in the department of Otolaryngology and Head-Neck Surgery, at Dhaka Shishu Hospital and Apollo Hospitals, Dhaka from January, 2007 to July, 2008. The data of patients included age, sex, presenting symptoms and signs, preoperative investigations like pure tone audiometry (PTA) and Impedance test, operation notes, complications of surgery and state at follow up. Results: This study included 198 males and 132 females. 222 patients (67.27%) were in the age group of 2-5 years. Main presenting symptom was fullness of the ear (50.30%) and main presenting sign was dull eardrum (72.18%). Turning fork test and PTA have been done in the age group of 7-10 years. In 166(59.30%) patients Impedence was type B. 222 (66.69%) patients have been cured with medical treatment. 69(20.90%) patients underwent grommet insertion as medical treatment has been failed in those patients. Two patients developed postoperative chronic suppurative otitis media with central perforation and one patient developed thinned tympanic membranes that have been treated conservatively. Conclusion: Chronic otitis media with effusion is usually not a threat to life but result in complications. As long as fluid is present in the middle ear, hearing will be affected. Hearing problems can interfere with language development in children. Any fluid that lasts longer than 3 months should be treated surgically.

Published: May 2010

A cross sectional study was conducted at the Department of Otolaryngology and Head-Neck surgery, Dhaka Medical College Hospital, Dhaka during the period of July 2005 to June 2007 to determine whether chronic suppurative otitis media (CSOM) can cause sensorineural hearing loss (SNHL) and to note its degree and its relation to duration of disease. 130 patients with unilateral CSOM were included in the study age ranging from 11 to 50 years after exclusion of other possible causes of SNHL such as meningitis, head injury, previous ear surgery, and chronic noise exposure. The use of unilateral CSOM cases provided a contralateral ear to serve as a control thus excluded common variables, such as presbycusis, parenteral ototoxic medications, metabolic disorders, and the effect of sex or genetics. Bone conduction threshold elevation between diseased and control ear was considered as the indicator of inner ear damage. In this series, CSOM is seen to be associated with sensorineural hearing loss. The study showed a bone conduction threshold elevation from 4.1dB to 10.7dB across frequency ranges. Significant threshold elevation was observed in relation to the disease duration. The average bone conduction loss at 4 kHz was higher than the average at the speech frequency range. This study suggests that CSOM can cause significant bone conduction threshold elevation and it should be considered when managing this problem. Early detection and prompt treatment may limit this potential handicap.

Catalysts are important to the chemical industry and environmental remediation due to their effective conversion of one chemical into another. Among them, composite catalysts have attracted continuous attention during the past decades. Nowadays, composite catalysts are being used more and more to meet the practical catalytic performance requirements in the chemical industry of high activity, high selectivity and good stability. In this paper, we reviewed our recent work on development of composite catalysts, mainly focusing on the composite catalysts obtained from porous materials such as zeolites, mesoporous materials, carbon nanotubes (CNT), etc. Six types of porous composite catalysts are discussed, including amorphous oxide modified zeolite composite catalysts, zeolite composites prepared by co-crystallization or overgrowth, hierarchical porous catalysts, host-guest porous composites, inorganic and organic mesoporous composite catalysts, and polymer/CNT composite catalysts.

This work presents a new synthetic approach to aromatic and aliphatic polycarbonates by melt polycondensation of bisphenol A diacetates with alkylene- and arylenediphenyl dicarbonates. The diphenyl dicarbonates were prepared from phenyl chloroformate and the corresponding dihydroxy compounds. The process involved a precondensation step under a slow stream of dry argon with the elimination of phenyl acetate, followed by melt polycondensation at high temperature and under vacuum. The potential of this reaction is demonstrated by the successful synthesis of a series of aromatic-aromatic and aromatic-aliphatic polycarbonates having inherent viscosities from 0.19 to 0.43 dL/g. Thus low to intermediate molecular mass polymers were obtained. The 13C-NMR spectra of the carbon of the carbonate group showed that the formed polycarbonates contain partial random sequence distribution of monomer residues in their chains. The polycarbonates were characterized by inherent viscosity, FTIR, 1H-NMR and 13C-NMR spectroscopy. The glass transition temperatures, measured by DSC, of the polycarbonates were in the range 13–108 ºC. The thermogravimetric curves of showed that these polymers have good thermal stability up to 250 ºC. The present approach may open the door for novel polycarbonates containing other organic functional groups.
Controlling the Mdm2-Mdmx-p53 Circuit

Published: May 2010

The p53 tumor suppressor is a key protein in maintaining the integrity of the genome by inducing either cell cycle arrest or apoptosis following cellular stress signals. Two human family members, Mdm2 and Mdmx, are primarily responsible for inactivating p53 transcription and targeting p53 protein for ubiquitin-mediated degradation. In response to genotoxic stress, post-translational modifications to p53, Mdm2 and Mdmx stabilize and activate p53. The role that phosphorylation of these molecules plays in the cellular response to genotoxic agents has been extensively studied with respect to cancer biology. In this review, we discuss the main phosphorylation events of p53, Mdm2 and Mdmx in response to DNA damage that are important for p53 stability and activity. In tumors that harbor wild-type p53, reactivation of p53 by modulating both Mdm2 and Mdmx signaling is well suited as a therapeutic strategy. However, the rationale for development of kinase inhibitors that target the Mdm2-Mdmx-p53 axis must be carefully considered since modulation of certain kinase signaling pathways has the potential to destabilize and inactivate p53.
A Comparative Study of Transmembrane Diffusion and Permeation of Ibuprofen across Synthetic Membranes Using Franz Diffusion Cells

Published: May 2010

Synthetic membranes used in Franz diffusion cells for topical formulation quality assessment should provide least resistance to drug diffusion. In this study, the diffusion rates of ibuprofen across thirteen membranes were determined using Franz diffusion cells. Correlation of the membrane thickness, pore size and MWCO with drug fluxes was also made. The drug diffusion results showed that the porous membranes were categorized into high-flux (8–18 mg/cm2/h) and low-flux (0.1–3 mg/cm2/h) membranes. The drug fluxes did not show strong correlations (r2 < 0.99) with membrane parameters. Synthetic membranes can give variable drug fluxes, thus investigators should be careful in choosing membrane for formulation quality assessment.
Detecting Nano-Scale Vibrations in Rotating Devices by Using Advanced Computational Methods
Authors: Del Toro Raúl M. , Haber Rodolfo E. , Schmittdiel Michael C.
Published: May 2010

This paper presents a computational method for detecting vibrations related to eccentricity in ultra precision rotation devices used for nano-scale manufacturing. The vibration is indirectly measured via a frequency domain analysis of the signal from a piezoelectric sensor attached to the stationary component of the rotating device. The algorithm searches for particular harmonic sequences associated with the eccentricity of the device rotation axis. The detected sequence is quantified and serves as input to a regression model that estimates the eccentricity. A case study presents the application of the computational algorithm during precision manufacturing processes.

Published: May 2010

At present, hyperspectral images are mainly obtained with airborne sensors that are subject to turbulences while the spectrometer is acquiring the data. Therefore, geometric corrections are required to produce spatially correct images for visual interpretation and change detection analysis. This paper analyzes the data acquisition process of airborne sensors. The main objective is to propose a new data format called Diffused Matrix Format (DMF) adapted to the sensor's characteristics including its spectral and spatial information. The second objective is to compare the accuracy of the quantitative maps derived by using the DMF data structure with those obtained from raster images based on traditional data structures. Results show that DMF processing is more accurate and straightforward than conventional image processing of remotely sensed data with the advantage that the DMF file structure requires less storage space than other data formats. In addition the data processing time does not increase when DMF is used.

This case report describes a cervical fusion cage, surgical technique and the long-term outcome of caudal cervical arthrodesis used to stabilise dynamic spinal cord compression at the sixth and seventh cervical intervertebral disc space (C6, C7) in a dog. A seven-year-old, 41 kg, entire male Dobermann Pinscher was admitted for progressive ataxia of two weeks duration. Neurological examination revealed ambulatory tetraparesis. Computed tomographic myelogram scans in neutral and traction positions of the neck were performed and were used to determine presence of a dynamic component. A C6-C7 surgical distraction and stabilisation using a distractable intervertebral fusion cage was performed. There was not any deterioration of neurological status was observed on postoperative neurological evaluation. Within eight weeks after surgery, gait and postural abilities had returned to normal. Computed tomography evaluation indicated a complete bridging callus within and outside the cage at 15 weeks after surgery. There were not any complications or recurrences of initial neurological deficits observed during the 40 month follow-up period. Based on the follow-up period data, a C6-C7 dynamic spinal cord compression with disc protrusion was successfully treated by a distractable cervical fusion cage.
