This report presents (1) the basic ideas of bootstrapping when applied to multiple linear regression, as described in [2, 3], and (2) how to implement these ideas using Arc, the computer package that accompanies [1].

This study explores the application of zigzag-shaped, finless tubes in enhancing heat transfer performance within exchangers. Using three-dimensional numerical simulations, we examined per unit area and volume pressure drop, comparing these findings with a traditional parallel tube exchanger. innovative design strategy involved arranging zigzag-shaped at varying distances, thermal frictional ch...

Arc-shaped forceps are important in pharyngeal cancer surgery, endoscopic sinus surgery, and single port surgery. Rotating the gripper of an arc-shaped forceps with respect to its shaft axis can improve the manipulability of the forceps. Concentric pipe structures consisting of inner and outer pipes are often used for this purpose. The inner pipe transmits rotations from its proximal end to dis...

Extended surfaces are one of the most important approaches to increase the heat transfer rate. According to the Fourier law, the heat transfer increases by increasing the contact surface of body and fluid. In this study, the effect of heat transfer has been investigated on two sets of engineered porous fins, in which the balls with different materials are sintered together. The fluid flow throu...

Psilorhynchus kaladanensis, a new psilorhynchid, is described from the Kaladan basin of Mizoram, India. The new species is diagnosed by having the following combination of characters: caudal fin with small but distinct dark brown triangular spot at mid-base, slightly elongated dark mark near base of lower lobe, indistinct V-shaped vertical bar across center, dark brown oblique bar across fin an...
