The study was carried out in 103 patients with psoriasis, who had the consultation of dermatologist and rheumatologist. Answers for 6 questions mPEST (Psoriasis Epydemiology Screening Tool) modified questionnaire were estimated, each positive answer corresponded to 1, PEST ≥ 3 was suggested the presence of psoriatic arthritis (PsA), PEST < 3 was considered the absence of PsA. All the patients were examined by rheumatologist, the gold standard was CASPAR (ClASsification criteria for Psoriatic Arthritis) criteria. If necessary the instrumental tests were performed: roentgenography, ultrasound examination, magnetic resonance imaging (MRI) and laboratory tests. At PEST ≥ 3 diagnosis of PsA was suspected in 60 (58.2%) of 103 patients. Diagnosis of PsA was confirmed by CASPAR criteria in 47 (45.6%) patients. mPEST less than 3 was in 43 (41.7%) of 103 patients. Diagnosis of PsA was absent by CASPAR criteria in 29 (67.4%) patients. Newly diagnosed PsA was in 32 (52.4%) of 61 patients. Any rheumatic disease, mainly PsA, can develop with psoriasis. mPEST questionnaire in most cases reveals PsA in early stage, however, its isolated use is insufficient to establish an accurate diagnosis, it requires a clear diagnostic algorithm of the disease, including consultation of rheumatologist, clinical and instrumental examination.

Full textAbstract:
Tardive dyskinesia is a potentially irreversible, debilitating, hyperkinetic movement disorder that can result from dopamine receptor antagonists. Prompt recognition and resolution of symptoms are instrumental in preventing disease irreversibility, though current treatment options have fallen short of robust, effective, and long-term symptom control. In April 2017, the Food and Drug Administration (FDA) approved 2 new vesicular monoamine transporter 2 (VMAT2) inhibitors, deutetrabenazine and valbenazine, for chorea related to Huntington’s disease and tardive dyskinesia, respectively. These agents were pharmacologically modified from tetrabenazine, a VMAT2 inhibitor used off-label in the treatment of tardive dyskinesia. Despite FDA-labeled indications of deutetrabenazine and valbenazine, each agent was explored as a treatment option for those with tardive dyskinesia. In this study, the pharmacologic modifications of the 2 new VMAT2 inhibitors are described, with detailed explanation as to how these may impact clinical practice. The associated case series, observational studies, and clinical trials exploring their use in the treatment of tardive dyskinesia are reported with expert opinion on practice implication.

Objective To investigate the correlations between clinical, functional, and radiological outcomes in inpatients with coronavirus disease 2019 (COVID-19). Methods In this observational study, we recruited inpatients affected by moderate COVID-19 disease. The clinical evaluation comprised the Cumulative Illness Rating Scale (CIRS), numerical rating scale (NRS), modified Rankin scale (mRS), and the modified Borg dyspnea scale (mBDS). Respiratory involvement was assessed with computed tomography (CT) and graded with a CT-severity score (CT-SS). We retrospectively assessed functioning using the International Classification of Functioning, Disability and Health (ICF) codes of the Clinical Functioning Information Tool (ClinFIT) COVID-19 in the acute phase. Correlation analysis was performed 1) between clinical, instrumental, and functional parameters and 2) between ICF categories. Results The data showed statistically significant moderate correlations between CT-SS and the following categories: b152 “emotional functions” and b440 “respiratory functions”. Conclusion This is the first study to use the ICF framework in people with a moderate form of COVID-19 in the acute phase. Considering the correlations between some ICF categories and radiological findings, our results support the use of the ClinFIT COVID-19 for a comprehensive assessment of COVID-19 patients.

Full textAbstract:
One of the important characteristics of the surface properties of metal parts subjected to friction is hardness. Hardness measurements are important for determining the operational characteristics of parts and monitoring the technological regimes of surface modification. However, hardness measurements of thin modified layers made by different methods can lead to differences in measurement results. The aim of the article was to study the hardness of a metal surface modified with ultrafine particles of minerals by two different methods (instrumental indentation and Vickers hardness measurement) and a comparative analysis of the measurement results obtained by these methods.Standard Vickers hardness measurements at loads of 0.025, 0.1 and 0.5 kgf showed a qualitative difference between the hardness values of the two samples modified with different mixtures of ultrafine particles of minerals and a large heterogeneity of the hardness values over the area. By the method of instrumental hardness, standard measurements were performed without preliminary selection of the indentation site (at a load of 1.05 N) and measurements during indentation into even sections (at low loads of 10 mN).It is noted that the high precision of measurements implemented by instrumental indentation, due to the large roughness of the samples, leads to large values of the error in calculating the measurement results. An additional difference in the results of measurements performed by two methods at shallow indentation depths may be due to the fact that the object under study has a complex structure consisting of a metal matrix and particles distributed over the depth of the sample. A possible way out of the situation lies in the transition from the use of hardness measures when calibrating instruments to standard samples of properties for which the constancy of mechanical properties in the measured range of indentation depths will be ensured, but which are not yet available in research practice. Therefore, at present, when carrying out work related to the search for optimal conditions for obtaining thin wear-resistant layers on the surface of metals modified with ultrafine particles of minerals, comparative measurements performed by one measurement method are recommended.

Objective: to evaluate clinical and instrumental characteristics of axial lesion in psoriatic arthritis (PsA) in real-life clinical practice.Subjects and methods. Examination were made in 52 patients (32 men and 20 women) with back pain recorded either at the time of their admission or in their medical histories. The inflammatory back pain (IBP) was diagnosed according to the Assessment of SpondyloArthritis international Society (ASAS) criteria. Back pain lasting over three months without meeting the ASAS criteria was taken to be chronic back (chrBP). Hands, feet, pelvis, cervical spine (CSP) and lumbar spine (LSP) were X-rayed. Erosions, osteolysis, and periarticular osteo-proliferative lesions were evaluated applying PsA-modified Sharp/van der Heijde score (SHS). Sacroiliitis (SI) was considered radiologically significant (r-sSI) when it was bilateral grade II or higher, or unilateral grade III or higher by Kellgren. 15 patients without r-sSI had their sacroiliac joints (SIJs) scanned using magnetic resonance imaging (MRI). Syndesmophytes, paravertebral ossifications, constriction and ankylosis of the CSP zygapophysial joints were considered to be radiological signs of psoriatic spondylitis. HLA-B27 typing was performed in 45 patients.Results and discussion. IBP was identified in 34 (66.7%), chrBP in 17 (33.3%) patients; 15 patients (28.8%) were of advanced age (over 40) at the onset of IBP/chrBP; 30 cases (57.7%) had r-sSI; in 18 cases SI was not detected. 13 out of 30 r-sSI patients (43.3%) didn’t suffer IBP. Erosions were detected in 38 (76%) patients, osteolysis in 13 (26%) and osteo-proliferative lesions in 18 (36%) patients. Average SHS was 82.79±64.77 correlating with the presence of r-sSI (r=0,46; p<0,05). Correlation of r=0.35 was found between r-sSI and the spine limited mobility according to Bath Ankylosing Spondylitis Metrology Index (BASMI); r-sSI was detected with much higher statistical significance in the presence of periarticular osteo-proliferative lesions than in the absence of such (р=0.02). In PsA patients having periarticular osteolysis, axial lesion in the form of asymmetric syndesmophytes was detected ten times more frequently than in those not having it (OR=10; 95% CI: 1.63–61.327). In CSP, syndesmophytes developed two times more frequently than in LSP (p=0.01). Discrete CSP lesions in the absence of any LSP changes was observed in 30% of cases. SI was MRI detected in 2 (13.3%) patients. In 9 (18.0%) patients axial lesions were observed without SI. 15 patients (33.3%) were HLA-B27 positive. A set of specific PsA axial skeletal involvement features were revealed: possibility of oligosymptomatic clinical presentation; patient’s advanced age at the back pain onset; association with severe destructive peripheral arthritis; and more pronounced CSP lesions as compared to LSP. An alternative phenotype patient group (18%) without X-ray or MRI SI but with spine involvement was identified. Key words: psoriatic arthritis; axial lesion>˂ 0,05). Correlation of r=0.35 was found between r-sSI and the spine limited mobility according to Bath Ankylosing Spondylitis Metrology Index (BASMI); r-sSI was detected with much higher statistical significance in the presence of periarticular osteo-proliferative lesions than in the absence of such (р=0.02).

Full textAbstract:
Aceclofenac (ACL) is an anti-inflammatory drug, which is taken by patients who mainly suffer from rheumatoid conditions. In this work, we propose a new voltammetric method that allows the determination of ACL in pharmaceutics, urine, and plasma. As a working electrode, a glassy carbon electrode (GCE) modified with carbon nanofibers, carbon nanotubes, and NiCo nanoparticles (eCNF/CNT/NiCo-GCE) was used. The mentioned sensors are characterized by good repeatability and sensitivity, and their process of preparation is simple, fast, and cost-effective. Instrumental and method parameters were optimized, and the influence of interferences was investigated. To validate the analytical performance of the method, calibration was conducted. Good linearity was obtained (0.05–1.4 µM, r = 0.998), as well as excellent limit of detection (LOD) and limit of quantification (LOQ) values (0.7 nM and 2.1 nM, respectively). Calculated recoveries that were in the range of 98%–105% indicate that this method is accurate and might be used in routine laboratory practice.

Full textAbstract:
Fibromyalgia is a disease that remains unrecognized due to ignorance and misinterpretation of symptoms. This article presents a clinical case from the medical practice of Fibromyalgia, while characterizing the pain syndrome and the necessary tests to prove the diagnosis. The clinical case concerned a patient with lumbar pain syndrome who did not respond to non-steroidal anti-inflammatory drugs. No connection has been established with the diseases provided for in the differential diagnosis, such as disc herniation, acute arterial insufficiency, rheumatoid arthritis. The laboratory tests performed are normal, except for a slight increase in AST of about 200 U / l, as well as high CRP values. No instrumental studies such as endophotonic emission computed tomography (SPECT), positron emission tomography (PET), magnetic resonance imaging (MRT) and electroencephalogram (EEG) were performed. The case describes a modified symptom in the elderly. Modified symptoms are experienced differently by patients. In this case, our own (from the doctor’s experience) paradigm was used for diagnosis. The paradigm consists of four main steps, which are: description of the specifics of each symptom; two aspects of the diagnosis: what is and what is not; the symptoms form a whole which represents the diagnosis with a logical connection and sequence and analysis of small deviations and nuances - a way of accurate diagnosis. The burning nature of the pain, the presence of painful nodules in the lumbar and scapular areas bilaterally, point to myositis. Various non-steroidal anti-inflammatory drugs have been administered in various forms (oral, topical and injectable), with no effect. As a last resort, a tricyclic antidepressant, amitriptyline, was included, which showed that the pain disappeared within a month. The presence of a mental component in the field of rheumatic disease, the effect of amitriptyline pain and the presence of sore spots at the predilection sites, led to the disease “Fibromyalgia”. Diagnosis of fibromyalgia is necessary to comply with two conditions clinical analysis of pain with the detection of painful points and instrumental nuclear magnetic resonance imaging to demonstrate dysfunction of the central nervous system and electroencephalogram for sleep disorders. To improve the diagnostic process, it is necessary in practice to apply tests of hormones and neurotransmitters.

18565 Background: In order to describe the elderly population in Institut Curie and to determine if a brief multidimensional assessment may influence our decision to treat elderly patients with cancers we decided to realize a short assessment for each patient, 70 years and older. In a prospective study we evaluated such diverse areas as functional status, comorbidity, nutrition, polypharmacy and the presence or absence of geriatric syndromes. Methods: We studied 105 elderly cancer patients, median age 80 years with solid tumors. In addition to PS, their physical function was assessed by the activity of daily living (ADL) and instrumental activity of daily living (IADL) scales. During consultation comorbidities, Geriatric depression scale (GDS), the number of falls in the past year, concomitant medications, weight measurements and social environment were collected in a questionnaire. Cognitive functions were assesed if troubles were suspected. Blood tests were performed secondary. Results: To date 105 patients were evaluated : 10 % live in institution, 16% have no social environment, 35 % have a loss of autonomy in ADL and 7% were dependant. In the IADL: 30% presented a loss of autonomy and 24% were dependant. The median Body Mass Index (BMI) was 23.8 kg/m2, but the BMI was in 14% < 19kg/m2; 20% of the patients fall more than 2 times in the year and 53% have a suspicion of depression in the GDS in 4 items. 74% take more than 3 drugs per day. The median of comorbidities was 1.3. According to the results the decision of treatment was modified in 28% of patients. Conclusion: This questionnaire is not a replacement for the entire Comprehensive Geriatric assessment but is a reasonable prescreening instrument that may be performed in less than 15 minutes and be helpful to the clinician in his decision. No significant financial relationships to disclose.

Objective. To optimize a pelvic and lower abdominal cavity MRI protocol in the diagnosis of chronic pelvic pain (CPP) in women.Material and methods. A total of 57 reproductive-aged women with complaints of CPP were examined. The first stage of all patients after clinical and laboratory examination for clinical indications was performed ultrasound of the pelvis and abdominal cavity with dopplerometry. In the second stage, all the patients underwent an MRI using the standard Protocol, and then a modified Protocol. The final diagnosis was based on the results of a comprehensive examination, which included a clinical and neurological examination, gynecological examination, pelvic and abdominal ultrasound, radiography of the ileosacral joints and lumbosacral spine, fibrocolonoscopy and laparoscopy with morphological examination of the operating material (according to indications).Results. Forty-six (81%) patients were found to have gynecological factors for the development of CPP; 16 (28%) had extragenital factors. The examination results were verified by the data of surgical intervention (n = 16 (28%)), hysteroscopy (n = 21 (37%)), and laparoscopy (n = 9 (16%)) with morphological examination of biopsy specimens or surgical material.Comparing with the standard pelvic MR protocol provided evidence for the high diagnostic value of the modified protocol statistically significantly (p < 0.05): 99.2% sensitivity and 99.6% specificity.Conclusion. The developed non-contrast 1.5T MRI protocol for the pelvis permits MR images of the pelvis and adjacent anatomical areas to be obtained during one study without increasing time expenditures and upgrading equipment and software. The use of the protocol makes it possible to improve the quality of radiation diagnosis of gynecological and extragenital diseases in CPP and to recommend that the protocol in combination with other clinical and instrumental studies be introduced in clinical practice.

Full textAbstract:
Purpose The purpose of this study is to present a systematic assessment of the distinctive challenges and opportunities associated with creating leadership within the realm of social enterprise. A modified and expanded form of Grint’s leadership lenses heuristic framework (i.e. person, position, process, performance, purpose and place) is used to examine and highlight what is particular about creating leadership in social enterprises by virtue of their distinctive missions, strategic contexts, legal forms and organisational structures and cultures. Based on this initial exploration, five research priorities are identified to better understand and then develop leadership practice in the social enterprise realm. Design/methodology/approach An enhanced heuristic framework for systematically examining leadership within the social enterprise research literature has been applied, drawing on the leadership practice literature. The application is illustrated through six instrumental case studies. Findings While there are a number of similarities between leading in the social enterprise realm and leading within the private, public and not-for-profit sectors, the levels of complexity, ambiguity and the lack of an established theoretical and practical knowledge base makes creating leadership in the social enterprise sector that much more challenging. On the positive side of the ledger, the fact that the purpose is at the core of social enterprise means that it is relatively easier to use the purpose to create a basis for common meaningful action, compared to leadership within the private and public sectors. Related to this, given the strongly local or “glocal” nature of social enterprise, a ready opportunity exists for leaders to draw upon a place as a strategic resource in mobilising followers and other stakeholders. The novel, uncertain and pioneering nature of a social enterprise is also arguably more tolerant and accommodating of a leadership mindset that focuses on posing questions regarding “wicked” problems compared to public, private for-profit and, indeed, traditional not-for-profit sector organisations. Originality/value As far as we can ascertain, this is the first systematic attempt to examine the distinctive challenges and opportunities associated with creating leadership within the social enterprise realm. The application of the heuristic framework leads to the identification of five key inter-related lines of empirical research into leadership practices within social enterprises.

Full textAbstract:
This book provides clinicians with a theoretically motivated guide to the assessment of patients with cognitive complaints. Its main goal is to teach physicians, psychiatrists, and psychologists how to assess cognition in the clinic or at the bedside based around the instrument, the Addenbrooke’s Cognitive Examination (ACE), developed in Cambridge over many years and subsequently refined and modified. The latest version is the ACE-III, which is freely available and has been translated into many languages. The early chapters provide a framework in which aspects of cognition are considered as those with a distributed representation in the brain (such as attention and memory) versus those with more focal representation (such as language, praxis, and spatial abilities). There are descriptions of the major syndromes encountered in clinical practice, notably delirium and dementia, which have been updated to incorporate recent discoveries. There follows the all-important section on history taking and the ‘meat of the book’: how to perform bedside cognitive testing. The ACE-III is contrasted to other commonly used brief standardized mental test schedules (such as the Montreal Cognitive Examination). Sixteen cases with a full range of cognitive disorders illustrate the method recommended. Finally, there is an appendix outlining the range of formal tests commonly used in neuropsychological practice.

Full textAbstract:
Unambiguous and homogeneous geodetic reference frames are essential to the proper determination of locations and heights. The reference frames used in the Netherlands are the Rijksdriehoekmeting (RD) for locations and the Normaal Amsterdamse Peil (NAP) for heights. The RD has traditionally been managed by the Kadaster; the NAP by Rijkswaterstaat. The emergence of satellite positioning has resulted in drastic changes to these geodetic reference frames. A surveyor is now offered one instrument, GPS (the Global Positioning System), capable of the simultaneous determination of locations and heights. This is possible by virtue of one three-dimensional geodetic reference system - the European Terrestrial Reference System (ETRS89) - which in the Netherlands is maintained in a collaborative arrangement between the Kadaster and Rijkswaterstaat. GPS has been advanced as a practical measurement technique by linking the definition of the RD grid to ETRS89. Nevertheless the introduction of GPS also revealed distortions in the RD grid, which are modelled in the RDNAPTRANSTM2004 transformation. Furthermore, the use of the geoid model has become essential to the use of GPS in determining the height in comparison to NAP. Subsidence that has disrupted the backbone of the NAP gave cause to the need for a large-scale adjustment of the heights of the underground benchmarks and, in so doing, of the grid. Consequently new NAP heights have been introduced at the beginning of 2005; a new definition of the RD grid that had already been introduced in 2000 was once again modified in 2004. During the past few years two NCG subcommissions have devoted a great deal of time to these modifications. This publication lays down ETRS89, the RD and the NAP, together with their mutual relationships. In addition to reviewing the history of the reference frames and the manner in which they are maintained (including, for example, the use of AGRS.NL as the basis for the Dutch geometric infrastructure), the publication also discusses the status of the frames as at 1 January 2005. This encompasses the realisation of ETRS89 via AGRS.NL, the revision and new definition of the RD grid in 2004, and the new NAP publication in 2005. The publication also describes the mutual relationships between the frames in the modernized RDNAPTRANSTM2004 transformation consisting of the new NLGEO2004 geoid model and a model for the distortions of the RD grid. In conclusion, the publication also devotes attention to the future maintenance of the ETRS89, RD and NAP. The continuity of the link between the traditional frames and the three-dimensional frames is of great importance, and ETRS89 will continue to fulfil this linking role. The GPS base network and AGRS.NL reference stations will increasingly assume the leading role in the maintenance of the RD frame. The maintenance of the NAP will continue to be necessary, although during the coming decades the the primary heights will not need revision. In so doing the high quality of the geodetic reference frames required for their use in actual practice will continue to be guaranteed.

Full textAbstract:
Chapter 6 is a detailed study of Sunday schools as sites of pedagogical practice in India. Guided by “tact” as a principle of conducting their work, Anglo-American Protestant missionaries, in order to secure and retain enrollment in their Sunday schools, jettisoned or substantially modified a number of clearly held Christian principles. They denounced racism, but closely allied themselves with a colonial militarist power that would not brook racial integration, and correspondingly instituted racial segregation in their Sunday schools. A second manifestation of “tact” was their borrowing of a number of schooling and cultural practices of the “idolatrous” Hindus, resulting in a type of Christian institution that began to look casteized even to Christian observers. Highly Sanskritized Sunday school hymns, Hindu religious musical forms, visual arts, and festive observances were made a part of the Christian Sunday school. All this benefited a number of Christian converts from the “lower castes” of Hindu society, inasmuch as they were able to acquire those symbolic resources traditionally denied them by the “upper castes.” But at the same time, the mimicking of such practices by Christian institutions underscored the prestige that certain Hindu traditions enjoyed. Also, and worryingly for missionaries, the “upper castes” began to organize their own Sunday schools without Christian doctrine, but mimicking elements of Anglicized, Christian Sunday schools that had seemed attractive to them to begin with. Further, to counter competition, missionaries expanded the Sunday school curriculum, but in the process mimicked secular institutions and undermined the evangelical thrust of their program. And finally, to solicit funds back home, missionaries sensationalized accounts of their work in India. Instrumental reasoning pervaded all aspects of their management of Sunday schools.

Full textAbstract:
Supported by government funds, many Jewish communities were able to renovate or build new synagogues beginning in the 1950s, a development that peaked around 1960. The organ, however, once a visual and aural symbol of Reform and acculturation could hardly be found in the new sacred spaces and was even removed from existing ones. With regard to the organ in the synagogue, cultural mobility’s obliqueness between change and persistence or continuity does not quite apply in the postwar era. Change had already occurred with the pogroms of November 1938, when the vast majority of instruments were destroyed. As one of the least fixed elements of Jewish musical practice, the organ still left its mark in postwar Germany in different ways: absence, silent presence, and adapted or modified presence. While being a nearly immovable artifact and a constituent of Jewish culture in later modernity, in the postwar era it embodied the near absence of liberal Judaism.

The study aims to find the short-run empirical analyses of the impact of oil price fluctuation on the monetary instrument (Exchange rate, Inflation, Interest rate) in Nigeria. We explored the frequently used Toda–Yamamoto model (TY) model, by adopting the TY Modified Wald (MWALD) test approach to causality, Forecast Error Variance Decomposition (FEVD) and Impulse Response Functions (IRFs).The study covered the period 1995 to 2018 (monthly basis), and our findings from MWALD test indicated that there is a uni-directional causality of the log of oil price (lnoilpr) to log of the exchange rate (lnexchr) at 10% level of significance, also there is a contemporaneous response of log of consumer price index (lncpi) to log of exchange rate (lnexchr) and log of interest rate (lnintr), and jointly (lnoilpr, lncpi and lnintr) granger cause lncpi. Also at 5% level of significance lnintr responded due to positive change in lnoilpr and lnexchr, and jointly causes lnintr at 5% level of significance. This is complimented with our findings in FEVDs, and IRFs. The empirical analyses shows that oil price is a strong determining factor of exchange rate, cost of borrowing and directly influences inflationary or deflationary tendencies in Nigeria..

Full textAbstract:
Arthroscopic surgery offers many advantages compared to traditional surgery. Nevertheless, the required skills to practice this kind of surgery need specific training. Surgery simulators are used to train surgeon apprentices to practice specific gestures. In this paper, we present a study showing the contribution of 3D sound in assisting the triangulation gesture in arthroscopic surgery simulation. This ability refers to the capacity of the subject to manipulate the instruments while having a modified and limited view provided by the video camera of the simulator. Our approach, based on the use of 3D sound metaphors, provides interaction cues to the subjects about the real position of the instrument. The paper reports a performance evaluation study based on the perception of 3D sound integrated in the process of training of surgical task. Despite the fact that 3D sound cueing was not shown useful to all subjects in terms of execution time, the results of the study revealed that the majority of subjects who participated to the experiment confirmed the added value of 3D sound in terms of ease of use.

The article summarizes the accumulated practical experience of the authors in the development of algorithms for the formation of investment strategies. For this purpose, the optimization of the studied parameters, information support of investment activities, verification, monitoring and adjustment in the testing mode and the subsequent practical application of the described tools are considered. The system is based on the main provisions of the Markowitz portfolio theory. The analytical block of the Information System Portfolio Investor includes Profitability-Risk model; empirical models of optimal complexity; hybrid predictive model systems; the principle of combining (integrating) both models and forecasts, as well as decision rules; optimization of the training sample length (modified Markowitz model); optimization of the frequency of monitoring and adjusting the composition of the investment portfolio. The principles of design and development of the information block of the system, its replenishment and functioning are described in detail. All the above listed components of the algorithmic content of the investment decision making system are described sequentially. The system modules have been successfully tested on a wide class of financial instruments: ordinary shares, preferred shares, government and corporate bonds, exchange commodities, stock, commodity, industry and bond indices, exchange-traded investment funds and real estate funds. The implemented Markowitz model with a dynamic database of historical data can significantly increase the efficiency of investment decisions, which is facilitated by taking into account the characteristics of both the markets under study and the corresponding financial instruments.

Full textAbstract:
This paper describes the design optimization study of an under platform damper to mitigate high vibration problem of a gas turbine rotor blade under resonance condition. An existing theoretical model explicitly, Casba friction damper model was used to evaluate the dynamic characteristics of the turbine blade with under platform damper. Turbine blade is approximated as two degrees of spring-damper-mass system, which is dynamically equivalent to real turbine blades for its first two eigen values. Blade tip response predictions were carried out for different damper mass, stiffness and coefficient of friction under simulated rotational speed of the rotor, to arrive at an optimum mass to control the blade tip response. As a practical application, along with damper mass optimization, shape and mass distribution of the damper is obtained by design trials to ensure good contact between the blade root and damper upper surface. Contact analysis was carried using the ANSYS software. The asymmetric skewed damper geometry posed complications with respect to modelling and optimisation. In realistic application, with the kind of uncertainties in contact pattern, variation in friction coefficient, geometric tolerances, validation/verification plays a major role in assessing the design. As part of verification of this damper design, a full scale gas turbine engine test program was envisaged and completed. Modified optimum damper was implanted as a design change, engine was instrumented for blade vibration measurement. Non-Intrusive Stress Measurement system was used for measuring blade tip amplitudes from all the blades in the rotor. Test blade tip vibration was analysed and compared against the predications. This optimised damper configuration has showed significant reduction in blade amplitudes during full-scale gas turbine testing, in comparison to original design proving the efficacy of new modified damper.

"Bearing Housing Design for Vibration Control, Using Tilting Pad Bearings Instead of Lemon-Bore Type on a Gas Turbine." In ASME 2020 International Mechanical Engineering Congress and Exposition. American Society of Mechanical Engineers, 2020. http://dx.doi.org/10.1115/imece2020-24330.
Full textAbstract:
Abstract Heavy duty gas turbines are usually equipped with hydrodynamic bearings which are either lemon-bore or tilting pad type. Baker Hughes legacy gas turbines use these two types of bearings, and its selection is based on 1) considering pros & cons from Rotor dynamics, 2) bearing performance, 3) bearing housing stiffness, 4) vibration detection & control. Non-contact probes are used to monitor the vibrations of rotor. Majority of legacy gas turbines are not equipped with these probes. Due to this fact, over the years it resulted in non-detection of dynamics & vibration issue, which caused frequent bearing replacement. As the increase in industry demand to apply and measure vibrations using non-contact probes on bearings, an effort was made by Baker Hughes to implement these on existing fleet units. Also, in order to increase rotor dynamics stability of low-pressure rotor, to improve bearing life and performance, effort was made to replace lemon-bore bearings with tilting pad. This paper demonstrates efforts made to design the titling pad which would fit within envelop of already available bearing housing. Bearing/shaft clearance, bearing performance, modification of bearing retainer clearances are the mandatory tasks which would be dealt in this study. The swap of bearing type, and its effect on whole gas turbine rotor dynamic stability, checking the frequency crossovers with Campbell diagram would also be dealt in this paper. This paper also focuses on assessment on oil passage routing, temperature & proximity probe instrumentation routing design. Re-design is performed by analyzing various configuration, assessing different sensitivity studies & validation of modified bearing housing from structural integrity, ultimate load capability, & split plane oil leakage retention and its comparison with baseline are most important aspects of finalization of this change, which will be showcased in this paper. Instrumentation routing was a critical task when the considering bearing replacement from lemon-bore to tilting pad. As lemon-bore type bearings just have an elliptical inner surface, it’s quite easy to install the thermocouples into a simple hole. But as replacement has tilting pads, the challenge is to instrument the pads without effecting their movement and functionality. Such best practices are also dealt in this paper. Comparison of tilting-pad with lemon-bore, considering the fixed shaft diameter, the retainer outer diameter of tilting pad is higher than lemon-bore. This effect has a change in bearing seat on bearing housing, thereby reducing the effective stiffness of the housing, and the reduced split plane surface. To tackle this situation, several sensitivities were executed, by re-modifying the bolts and bolt holes on the existing housing, without modifying the housing envelop.

Full textAbstract:
The range of submarine detection is frequently limited by the refraction produced by vertical temperature gradients in the superficial layers of the ocean. In order to measure these temperature gradients and thus to permit predictions of the range, the bathythermograph was developed and is now being used on a considerable number of anti-submarine vessels, while a somewhat modified version of the instrument is being tried out on submarines. Some 6675 bathythermograph observations from the western North Atlantic have been examined in order to determine how frequently such observations should be made so that within practical limits and anti-submarine vessel may at all times know the assured range of its sound gear. The occurrence of the four basic types of refraction patterns is shown by a series of six charts. For all but one of these patterns the range can be rather quickly and easily estimated from simple tables; but when the so-called afternoon effect is encountered, which is on the average about 20% of the time, a more complete analysis is necessary. It is found that under the most unfavorable circumstances, that is, in mid-summer and near the edges of a strong current system, there is about one chance in three that the refraction pattern will chance significantly in a distance of four miles. At other times of year and in areas where horizontal variations in temperature are less pronounced a single bathythermograph observation can be considered representative of a much larger area. It is also shown that in the western North Atlantic about 92% of the time in summer and about 34% of the time in winter the assured range of submarine detection is limited by refraction to less than 2500 yards.

Lehotay, Steven J., and Aviv Amirav. Ultra-Fast Methods and Instrumentation for the Analysis of Hazardous Chemicals in the Food Supply. United States Department of Agriculture, December 2012. http://dx.doi.org/10.32747/2012.7699852.bard.
Full textAbstract:
Original proposal objectives: Our main original goal was to develop ultra-fast methods and instrumentation for the analysis of hazardous chemicals in the food supply. We proposed to extend the QuEChERS approach to veterinary drugs and other contaminants, and conduct fast and ultra-fast analyses using novel 5MB-MS instrumentation, ideally with real samples. Background to the topic: The international trade of agricultural food products is a $1.2 trill ion annual market and growing. Food safety is essential to human health, and chemical residue limits are legislated nationally and internationally. Analytical testing for residues is needed to conduct risk assessments and regulatory enforcement actions to ensure food safety and environmental health, among other important needs. Current monitoring methods are better than ever, but they are still too time-consuming, laborious, and expensive to meet the broad food testing needs of consumers, government, and industry. As a result, costs are high and only a tiny fraction of the food is tested for a limited number of contaminants. We need affordable, ultra-fast methods that attain high quality results for a wide range of chemicals. Major conclusions, solutions and achievements: This is the third BARD grant shared between Prof. Amirav and Dr. Lehotay since 2000, and continual analytical improvements have been made in terms of speed, sample throughput, chemical scope, ease-of-use, and quality of results with respect to qualitative (screening and identification) and quantitative factors. The QuEChERS sample preparation approach, which was developed in conjunction with the BARD grant in 2002, has grown to currently become the most common pesticide residue method in the world. BARD funding has been instrumental to help Dr. Lehotay make refinements and expand QuEChERS concepts to additional applications, which has led to the commercialization of QuEChERS products by more than 20 companies worldwide. During the past 3 years, QuEChERS has been applied to multiclass, multiresidue analysis of veterinary drug residues in food animals, and it has been validated and implemented by USDA-FSIS. QuEChERS was also modified and validated for faster, easier, and better analysis of traditional and emerging environmental contaminants in food. Meanwhile, Prof. Amirav has commercialized the GC-MS with 5MB technology and other independent inventions, including the ChromatoProbe with Agilent, Bruker, and FUR Systems. A new method was developed for obtaining truly universal pesticide analysis, based on the use of GC-MS with 5MB. This method and instrument enables faster analysis with lower LaDs for extended range of pesticides and hazardous compounds. A new approach and device of Open Probe Fast GC-MS with 5MB was also developed that enable real time screening of limited number of target pesticides. Implications, both scientific and agricultural: We succeeded in achieving significant improvements in the analysis of hazardous chemicals in the food supply, from easy sample preparation approaches, through sample analysis by advanced new types of GC-MS and LCMS techniques, all the way to improved data analysis by lowering LaD and providing greater confidence in chemical identification. As a result, the combination of the QuEChERS approach, new and superior instrumentation, and the novel monitoring methods that were developed will enable vastly reduced time and cost of analysis, increased analytical scope. and a higher monitoring rate. This provides better enforcement, an added impetus for farmers to use good agricultural practices, improved food safety and security, increased trade. and greater consumer confidence in the food supply.
