Minor head loss can be expressed as: hminor_loss= ξ v2/ 2 g(3) where ξ=minor loss coefficient Since the velocity -v- in equation(2)in general is related to the pipe or duct where the component is located, the sum of the minor losses in a pipe or duct can be expressed as: ...
While the Henderson-Hasselbalch equation possesses no inherent flaws, its inadequacy for comprehensively understanding even basic systems is undeniable. Missing from the complete description is the essential charge-balance statement, which needs to address strong ions, total buffer concentrations, and water...
Artificial total hip arthroplasty (THA) is one of the most effective orthopaedic surgeries that has been used for decades. However, wear of the articulating surfaces is one of the key failure causes limiting the lifetime of total hip implant. In this pap

However, it is worth noting that the aforementioned equation indicates that the estimation of the fatigue life is highly dependent on the contact stress. Since the loading conditions that are applied to the acetabular head influence the contact stress, the load amplitude must be precise. 3.3.2. ...
Wear and wear-induced debris is a significant factor in causing failure in implants. Reducing contact pressure by using a textured surface between the femoral head and acetabular cup is crucial to improving the implant’s life. This study presented the effect of surface texturing as dimples on th...
The relation between the bubble size (𝑑𝑏db) and pore size (𝑑𝑜do) can be written in Equation (1), where g is gravitational acceleration, 𝜌ρ is the density of the liquid, and σσ is surface tension [39]. 𝑑𝑏𝑑𝑜=1.8 [σ𝜌𝑔𝑑𝑜2]1/3dbdo=1.8 [σρ...
From Equation (24) it follows that the decrease in the density of osteogenic cells is influenced by their natural death, determined by the coefficient 𝐴𝐶AC and growth factors of type 1, increasing the proliferation of osteoblasts, determined by the coefficient 𝛼CαC. In this regard, th...
