The dimension stone industry faces a significant environmental challenge due to the large amount of waste produced during the production process. About 51.3% of the materials extracted from dimension stone quarries worldwide end up as quarry waste. The presence of discontinuities and fractures primarily causes this waste. However, by examining the characteristics of these discontinuities and fractures and identifying in-situ blocks of the rock mass, it is possible to reduce the amount of waste produced during dimension stone quarrying. This study focuses on an abandoned quarry bench of the Las

As is known from the classic works on open pit mining, the bench is a separately developed part of the rock layer, having the form of a step. It should also be noted that it is necessary to clearly differentiate the concepts of “bench height” and “height of the layer to be removed.” The benches are often divided into subbenches, developed by different excavation equipment or by the same equipment both sequentially and simultaneously, but having transport routes that are uniform for the bench. As an example, an excavator stripping of the upper and lower subbenches with loading, respectively, at

Abstract In Japan, the rate of aging exceeds 27%, and the decline of communities has been an issue. Therefore, in this study we take the T housing complex as an example where the rate of aging is more than 40% and aim to understand the usage pattern of benches. An observational research was conducted for 19 days to examine the usage of a total of 23 benches, 17 existing ones and 6 newly installed ones, in the T housing complex. This investigation led to the findings. An average of 417 people used the benches in a day. Research determined that there are four different types of bench utilization

The blade pass frequency (BPF) noise for axial flow cooling fans in Electrical Vehicles (EV) is much obvious in some of rotational speeds. The root cause of this BPF noise is due to the cooling fan loading which is caused by the pressure difference between inlet and outlet of the fan. The pressure difference is defined as the resistance value of the fan. The resistance value of fan in EVs is much higher than the value of internal-combustion engine (ICE) vehicles. It is very difficult to obtain the resistance value in full vehicle condition. A new method to estimate the vehicle resistance value

Currently, there is no standard bench-scale dead-end ultrafiltration (UF) testing system. The aim of the present study was to design and build a bench-scale hollow fiber UF system to assess the impact of operational parameters on membrane performance and fouling. A bench-scale hollow fiber UF system was built to operate at a constant flux (±2% of the set-point flux) and included automated backwash cycles. The development of the bench-scale system showed that it is very difficult to maintain a constant flux during the first minute of the filtration cycles, that digital flow meters are problemat

Blood sampling often requires restraint that negatively affects animal welfare. This case study evaluated three methods for jugular vein blood sampling (V-bench, sling, and clicker training) with the overall aim of assessing the negative impact on animal welfare and providing a general recommendation on the use of methods. First, the effects of simulated blood sampling in V-bench and sling on behaviour, heart rate, and saliva cortisol concentrations 15 min after sampling were assessed. The sling (which had the least negative effects) was re-evaluated after one week of habituation to assess a p

The test bench was designed to solve the problem of measuring the oil film thickness of the liquid hydrostatic guideway of machine tools. And based on the fast overshoot of the classical PID control, introducing the self-antidisturbance control algorithm, this study established a mathematical model of the test bench electro-hydraulic servo control system. At the same time, this paper also designed a specific structure of the self-turbulence controller, which adopts optimal quadratic control, pole configuration, PID control, and self-turbulence control to study the control methods of the test b

For patients with end-stage kidney disease unable to receive a kidney transplant, replacement of kidney function with dialysis is necessary to extend life. Peritoneal dialysis (PD) and hemodialysis (HD) are the two major forms of dialysis therapy. HD involves the passage of blood via an extracorporeal circuit whereby removal of small solutes, toxins, and water is achieved across a synthetic, semipermeable dialysis membrane. In contrast, in PD, the dialysis membrane is the highly vascularized internal lining of the peritoneal cavity. Intraperitoneal installation of hypertonic high glucose PD so

Delay time is an important factor in the quality of bench blasting. The development and application of electronic detonators make it possible to control the timing of detonation by a highly precise delay time. It is an easily achievable way to seek a better blast fragmentation by controlling the delay time. In order to investigate the influence of delay time on rock fragmentation, eight experiments on bench blasting models with double holes were carried out. The average weight of 4.59 g of pentaerythritol tetranitrate (PETN) was charged into each blast hole with a diameter of 10 mm. Delay time
