Fabrication and Power Test of the Second MCBXFB Nested Orbit Corrector Prototype for HL-LHC

Background: The power performance of an electric vehicle is the basic parameter. Traditional test equipment, such as the expensive chassis dynamometer, not only increases the cost of testing but also makes it impossible to measure all the performance parameters of an electric vehicle. Objective: A set of convenient, efficient and sensitive power measurement system for electric vehicles is developed to obtain the real-time power changes of hub-motor vehicles under various operating conditions, and the dynamic performance parameters of hub-motor vehicles are obtained through the system. Methods: Firstly, a set of on-board power test system is developed by using virtual instrument (Lab- VIEW). This test system can obtain the power changes of hub-motor vehicles under various operating conditions in real-time and save data in real-time. Then, the driving resistance of hub-motor vehicles is analyzed, and the power performance of hub-motor vehicles is studied in depth. The power testing system is proposed to test the input power of both ends of the driving motor, and the chassis dynamometer is combined to test so that the output efficiency of the driving motor can be easily obtained without disassembly. Finally, this method is used to carry out the road test and obtain the vehicle dynamic performance parameters. Results: The real-time current, voltage and power, maximum power, acceleration time and maximum speed of the vehicle can be obtained accurately by using the power test system in the real road experiment. Conclusion: The maximum power required by the two motors reaches about 9KW, and it takes about 20 seconds to reach the maximum speed. The total power required to maintain the maximum speed is about 7.8kw, and the maximum speed is 62km/h. In this article, various patents have been discussed.

ABSTRAK Penelitian ini betujuan untuk memformulasikan krim dari ekstrak rimpang kunyit (Curcuma domestica Val.) untuk memperoleh sediaan yang stabil sebagai krim obat luka dengan variasi konsentrasi setil alkohol sebagai agen pengental. Dalam penelitian ini krim diformulasikan dengan variasi konsentrasi setil alkohol F I (4%), F II (7%), dan F III (10%). Evaluasi fisik sediaan krim yang dilakukan meliputi evaluasi organoleptis, homogenitas, daya lekat, daya sebar, pH, tipe krim, dan viskositas. Hasil uji menunjukkan ketiga formula menghasilkan krim berwarna warna kuning jingga kecoklatan, bau khas kunyit, dan sediaan dengan tekstur krim semisolid, memiliki homogenitas yang baik, kemampuan menyebar yang baik, pH sediaan yaitu 5,86; 5,66; 4,68 dan tipe emulsi M/A (Minyak dalam Air). Hasil uji viskositas menunjukkan FII dan FIII memiliki viskositas yang sesuai dengan persyaratan. Uji daya lekat menunjukkan bahwa ketiga formulasi krim belum memenuhi persyaratan daya lekat sediaan topikal yang baik. ABSTRACT This study aims to formulation creams from turmeric extract (Curcuma domestica Val.) to obtain stable preparations as a wound healing cream in the variations concentration of cetyl alcohol as a stiffening agent. In this study, the cream was formulated with variations concentration of cetyl alcohol F 1 (4%), F II (7%), and F III (10%). The formulation were evaluated basen on several parameter, that are organoleptic evaluation, homogeneity, adhesion, dispersion, pH, cream type, and viscosity. The evaluation showed that the three formulas produced cream with a brownish-yellow color, a distinctive smell of turmeric, and preparations with a semisolid cream texture, had good homogeneity, good dispersing ability, pH of the preparation namely 5.86; 5.66; 4,68 and type M / A emulsions (Oil in Water). The results of the viscosity test showed that FII and FIII has viscosity that is suitable with the requirements. The sticky power test showed that all cream formulations does not suitable with the requirements of good topical preparations.

Muscle Torque

Background The Stair Climb Power Test (SCPT) is a functional test associated with leg muscle power in older people. Objective The purposes of this study were to compare the results of the SCPT in people with chronic obstructive pulmonary disease (COPD) and people who were healthy and to explore associations of the SCPT with muscle strength (force-generating capacity) and functional performance. Design The study was a cross-sectional investigation. Methods Twenty-one people with COPD and a predicted mean (SD) percentage of forced expiratory volume in 1 second of 47.2 (12.9) and 21 people who were healthy and matched for age, sex, and body mass were tested with the SCPT. Knee extensor and flexor muscle torque was assessed with an isokinetic dynamometer. Functional performance was assessed with the Timed “Up & Go” Test (TUG) and the Six-Minute Walk Test (6MWT). Results People with COPD showed lower values on the SCPT (28%) and all torque measures (∼32%), except for eccentric knee flexor muscle torque. In people with COPD, performance on the TUG and 6MWT was lower by 23% and 28%, respectively. In people with COPD, the SCPT was moderately associated with knee extensor muscle isometric and eccentric torque (r≥.46) and strongly associated (r=.68) with the 6MWT. In people who were healthy, the association of the SCPT with knee extensor muscle torque tended to be stronger (r≥.66); however, no significant relationship between the SCPT and measures of functional performance was found. Limitations The observational design of the study and the use of a relatively small convenience sample limit the generalizability of the findings. Conclusions The SCPT is a simple and safe test associated with measures of functional performance in people with COPD. People with COPD show deficits on the SCPT. However, the SCPT is only moderately associated with muscle torque and thus cannot be used as a simple surrogate for muscle strength in people with COPD.
