An intermittent discharge waste stabilisation pond system was trialled for treatment of a seasonal wastewater load from a campsite. The system showed rapid acclimatisation to incoming load, with chlorophyll-a exceeding 700 mg l(-1) within 2 weeks and filtered and unfiltered effluent biochemical oxygen demand below 20 and 30 mg l(-1) respectively. Good performance continued for some weeks, after...

in this paper we investigate the effect of oil price shocks on stock market index in iran, by using of a structural var (svar) approach. we used four variables in the model namely kilian index, global oil supply, real oil price and real stock market index. the data are monthly and spanning the period 1997m10-2014m12. we identify the effect of four different shocks on stock market including oil ...

Abstract The microstructure of the shell is a kind “sandwich” structure with denser outer layer and less dense inner layer, density, which can be identified as functional gradient material in engineering. It has excellent performance, such earthquake resistance shock resistance. In order to study reliability this material, designed paper. range elastic deformation constraints simulate calculate...

BACKGROUND Aggregation and misfolded alpha-synuclein is thought to be central in the pathogenesis of Parkinson's disease (PD). Heat-shock proteins (HSPs) that are involved in refolding and degradation processes could lower the aggregate load of alpha-synuclein and thus be beneficial in alpha-synucleinopathies. METHODOLOGY/PRINCIPAL FINDINGS We co-overexpressed human A53T point-mutated alpha-s...

The gearbox is a complex system component and its core is the gear shafting. The gear system output the power to the drive shaft with speed changing through the engine. In the actual work, because of the installing error, load distortion and shock load situation, the correct meshing condition of gears was destroyed. 3D model of transmission gear was firstly built up by using SolidWorks software...

When conducting dynamic tests, when simulating shock effects, the measurement system - from sensor to data acquisition unit is subject significant overloads. In this circuit, accelerometer most vulnerable link. Therefore, piezoelectric accelerometers have become widely used in measuring shocks as more reliable and durable, but they also a number of disadvantages. Thus, under broadband vibration...

Degradation and overstress failures occur in many electronic systems which the operation load environmental conditions are complex. The dependency of them called dependent competing failure process (DCFP), has been widely studied. Electronic system may experience mutual effects degradation shocks, they considered to be interdependent. Both shock processes will decrease limit cause cumulative ef...

Abstract To study the damage of shock vibration generated by ship hull to internal equipment under secondary explosion impact, a three-dimensional simulation model BE rubber isolator was established. The signal impact load loaded AUTODYN software. And relationship between primary and frequency, amplitude, attenuation loading found. It is revealed that law curve conforms rational function. Based...

Analysis of angular dependences the diffraction peak broadening observed in α-uranium as-received state, after loading by converging spherical shock wave, low-speed uniaxial deformation, and annealing at 850°С has been presented this work. Broadening anisotropy identical for all states investigated demonstrated. The authors have attempted to explain phenomena Young’s modulus uranium or crystall...

The mechanism of blast damage to steel-clad concrete-filled steel tube (SCCFST) arched protective doors is studied using the dynamic response characteristics such loads under action shock wave loads, and ultimate load-bearing capacity formula derived based on “plastic hinge” mode limit analysis, which explores effect wave. design parameters each component door subjected waves discussed. Results...
