Abstract The steepness of the slopes an open pit mine has a substantial influence on financial return mine. paper proposes novel design methodology where overall steeper pitwalls are employed without compromising safety In current practice, pitwall profiles often planar in cross-section within each rock layer; i.e., profile inclination across layer tends to be constant. Here instead, new geotec...

The purpose of this study was to compare normative data from present Division I National Collegiate Athletic Association football teams to those from 1987. Players were divided into 8 positions for comparisons: quarterbacks (QB), running backs (RB), receivers (WR), tight ends (TE), offensive linemen (OL), defensive linemen (DL), linebackers (LB), and defensive backs (DB). Comparisons included h...

In this paper, we present BENCH (Biclusteringdriven ENsemble of Classifiers), an algorithm to construct an ensemble of classifiers through concurrent feature and data point selection guided by unsupervised knowledge obtained from biclustering. BENCH is designed for underdetermined problems. In our experiments, we use Bayesian Belief Network (BBN) classifiers as base classifiers in the ensemble;...

The aim of this study was to investigate the existence of the sticking region in two legged free weight squats. Fifteen resistance-training males (age 24 ± 4 years, body mass 82 ± 11 kg, body height 179 ± 6 cm) with 6 ± 3 years of resistance-training experience performed 6-RM in free weight squats. The last repetition was analyzed for the existence of a sticking region. Only in 10 out of 15 par...

In the present work we identified and quantified the effect of hydrodynamic stress on two different microalgae strains, Dunaliella tertiolecta and D. salina, cultivated in bench-scale bubble columns. The cell death rate constant increased with increasing gas-entrance velocity at the sparger. Dunaliella salina was slightly more sensitive than D. tertiolecta. The critical gas-entrance velocities ...

The digital model of the laboratory bench parts of digging deep rootstalk crops were established through adopting the parametric model technology based on feature. The virtual assembly of the laboratory bench of digging deep rootstalk crops was done and the digital model of the laboratory bench parts of digging deep rootstalk crops was gained. The vibrospade, which is the key part of the labora...

Objectives: While it has been suggested that resistance training may have a beneficial effect on psychological health in young people, evidence supporting this assertion is limited. The primary aim of this study was to explore the effect of free weights and elastic tubing resistance training on physical selfperception in adolescents. Design: Randomized controlled trial. Method: Participants (N1...

Abstract Aim Strength training induces a mechanical load, both increasing muscle mass and enhancing osteoblast activity. This results in increased bone strength, reducing the risk of osteosarcopenia. Osteosarcopenia can start after age 30, putting patients at fractures, with an untrained individual losing 0.23kg per year. In this case study, we illustrate programme, implemented over period 4 we...

The Smith machine (SM) (vertical motion of bar on fixed path; fixed-form exercise) and free weights (FWs) (free-form path) are commonly used strength training modes. Exercisers may need to alternate between types of equipment, depending on testing, training, rehabilitation, and/or the exercisers' goals. The purposes of this study were to compare muscle force production for SM and FWs using a 1 ...

ABSTRACF: Bench terracing's effect on erosion, soil characteristics, crop yields, and cropping area and socioeconomic factors that affect farmers views and use of bench terraces were evaluated in the Kerinci uplands of Sumatra , Indonesia. Bench terraces reduced soil loss 70% (P<0.05) on enclosed runoff plots in comparison to unterraced fields under the same cropping pattern. Erosion under benc...
