Parametric Modeling as a Technology of Rapid Prototyping in Light Industry

The paper deals with the parametric modeling method of virtual mannequins for the purposes of design automation in clothing industry. The described approach includes the steps of generation of the basic model on the ground of the initial one (obtained in 3D-scanning process), its parameterization and deformation. The complex surfaces are presented by the wireframe model. The modeling results are evaluated with the set of similarity factors. Deformed models are compared with their virtual prototypes. The results of modeling are estimated by the standard deviation factor

Mutual influence of intensity of pain syndrome and borderline mental disorders in patients with coxarthrosis

The objective of this study is to evaluate the mutual influence of pain syndrome and borderline psychiatric disorders depending on its intensity and tolerability in patients with coxarthrosis who need endoprosthetics. 76 patients with coxarthrosis aged from 25 to 68 who were hospitalized in the Department of Endoprosthetics at Mechnikov Regional Clinical Hospital in Dnipro City in the period from November 2015 to September 2016 were observed. For diagnosis of psychopathological disorders, and for evaluation of the effectiveness of therapeutic interventions, the following methods were used in our research: clinical and psychopathological (technique SCL-90-R), Tаylor anxiety scale, study of the type of attitude to the disease (LOBI), Dembo-Rubinstein self-esteem scale, Leonhard-Schmieschek questionnaire for assessment of accentuation of personality traits, the Luscher 8-colour test and the Toronto alexithymia scale (TAS). Severity of pain syndrome was assessed using a visual analogue scale of pain (VAS). Forms of borderline mental disorders were diagnosed in 51 patients with coxarthrosis, such as depressive disorder (F 32) – 19 (24.8%), neurasthenia (F 48) – 12 (16.2), anxiety and phobic disorders (F 40–41) – 14 (18.1%), and personality disorders (F 60.5, F 60.6, F 60.7) – 6 (7.6%). In 25 (33.3%) patients clinically-defined forms of mental disorders were identified. Leading syndromes in these disorders were depression – 19 (24.8%) patients, anxiety and phobic – 15 (20.0%), asthenic – 10 (12.4%), hypochondriacal – 7 (9.5%) patients. According to the results of the correlation analysis, a close correlation between the severity of pain syndrome and borderline mental disorders (r = 0.779) was established for patients in the preoperative stage. The average level of pain syndrome on the VAS scale in patients with borderline mental disorders was twice as high as in patients without these disorders (63.4 vs. 32.4 points), but it does not depend on the main psychopathological syndrome. The average level of pain on the VAS scale in patients with borderline mental disorders at the preoperative stage was twice as high as in patients without these disorders (63.4 vs 32.4 points), and after surgical intervention the level decreased only by 5.9 points or 9.3%. In patients with coxarthrosis with detected borderline mental disorders (51 people) the therapy had a complex character and was conducted both at the hospital stage for one month, and in the outpatient stage as "maintenance" therapy for 3 months or more. Therapy of the neurotic state with decompensation lasted on average 6 months. Treatment included psycho-educational and therapeutic arrangements (conversations, lectures, autotraining) and psychopharmatherapy (tranquilizers, antidepressants, antipsychotics in small and medium therapeutic doses). The conducting of simultaneous corrective measures for identified borderline mental disorders in patients of the main groups contributed to a significant reduction in the severity of pain within the six-month period of observation and moved them towards the level of the patients in the control group. Borderline mental disorders that take place in patients with chronic somatic diseases, which include, in particular, coxarthrosis, significantly amplify the severity of the condition, reduce the possibility of adaptation, and thus aggravate the course and the outcome of the main disease

An overview of the HIE-ISOLDE Design Study

The On-Line Isotope Mass Separator ISOLDE [1] is a facility dedicated to the production of a large variety of radioactive ion beams (RIB) for a great number of different experiments. Over 1000 radioactive nuclides from 70 elements can be produced in thick high-temperature targets via spallation, fission or fragmentation reactions with the PS-Booster pulsed proton-beam. With the arrival of CERN’s new linear accelerator Linac 4 [2] and [3], ISOLDE will have the possibility to exploit a factor of 3 increase in proton-beam intensity and a possible proton-beam energy increase from 1.4 GeV to 2 GeV [4]. After 20 years of successful ISOLDE operation at the PS-Booster, a major upgrade of the facility, the HIE-ISOLDE (High Intensity and Energy ISOLDE) project was launched in 2010. It is divided into three parts; a staged upgrade of the REX post-accelerator to increase the beam energy from 3.3 MeV/u to 10 MeV/u using a super-conducting Linac, an evaluation of the critical issues associated with an increase in proton-beam intensity and a machine design for an improvement in RIB quality. The latter two will be addressed within the HIE-ISOLDE Design Study. This paper gives an overview of the Design Study and will outline the critical issues to be addressed concerning the intensity upgrade and will propose solutions and improvements to be implemented. It will also give an insight to the propositions being studied in order to improve secondary beam characteristics essential to accomplish a more demanding physics program.publisher: Elsevier articletitle: An overview of the HIE-ISOLDE Design Study journaltitle: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms articlelink: http://dx.doi.org/10.1016/j.nimb.2013.07.030 content_type: article copyright: Copyright © 2013 Elsevier Ltd.
