This study investigated the risk factors for freezing of gait (FOG) in the early stage of Parkinson disease in China, using a sample of 248 patients who were followed for 3 years. Part III of the Unified Parkinson Disease Rating Scale and the modified Hoehn-Yahr grading scale were used to evaluate the severity of motor symptoms. Nonmotor symptoms were assessed using the Hamilton Anxiety Rating ...

Abstract Due to the phase-out of CFCs and HCFC refrigerants, propane is a nature refrigerant occurring substance produced by natural gas production oil refining. As result, has higher latent heat lower density than conventional refrigerants while maintaining comparable saturation pressure thermal conductivity. So, already widely used in domestic fridges freezers for many years. However, propane...

Forced convection on heat exchangers yields to higher heat exchange coefficient and so permits to limit the temperature difference between air and the evaporator. Higher energy performances of the refrigerating cycle is affordable compared to natural convection evaporators. In Europe, many refrigerators and freezers integrate natural convection heat exchangers. Making a review of the actual ene...

High orders of end use efficiency and reliability have been achieved in a refrigeration compressor which employs an electromagnetic linear motor. Techniques of computer-aided design were used to explore the operational characteristics of the moving-iron compressor and to simulate its operation. Application tests on prototype units developed through extensive feasibility and manufacturing studie...

Maximum rates of cooling for the Asymptote EF 100 and the Cryologic CL8800 temperature controller with either a standard or fast chamber were determined and viewed in the context of sperm cryopreservation. All three systems use liquid nitrogen to cool the plate or chamber which would hold the sample, opposed by a variable amount of heat from an internal heater. Maximum rates of cooling for all ...

The CO 2 emissions and energy use of SMEs in the tertiary sector (e.g. small food non-food shops, restaurants, offices, pubs, etc.) are high there few initiatives to reduce because this target group is difficult reach due scale diversity. Flemish-Dutch TERTS project wants (1) make aware potential (2) demonstrate transition efficiency innovative technologies. This paper focussing on butcher’s sh...

Recently, most of the commercial polyols used in production rigid polyurethane foams (RPUFs) have been derived from petrochemicals. Therefore, introduction modified palm oil derivatives-based polyol as a renewable material into formulation RPUFs is focus this study. A derivative—namely, methyl oleate (MO)—was successfully through three steps reactions: epoxidation reaction, ring-opened with gly...

There are many meat shop around the country and only few maintaining standard according to animal slaughter house inspection act, 2057. We trying evaluate of 122 Madi Municipality. have prepared a questionnaire surveyed all know condition their with reference Meat in is dominated by chicken, 85.71%. Which equipped D-freeze (60.65%) for freezing day 91.22% having backup support freezers. 70.08% ...
