The present work focuses on a detailed analysis of new and used braking friction partners (discs pads) in order to provide comprehensive characterization the source airborne particles formed during braking. Scanning electron microscopy (SEM) combined with energy dispersive X-Ray (EDX) was applied investigate brake disc pad components passenger vehicle. pads include at least 21 different substan...

This paper presents numerical studies of friction-induced instabilities of brake systems using complex mode analysis. The complex eigenvalue extraction is performed at a deformed configuration; thus, nonlinear effects are taken into account in the modal analysis. An example case is used to illustrate the importance of friction-induced damping and nonlinear effects in brake squeal analysis. It i...

In this paper we present an attack to the BLOKE and BRAKE hash functions, which are weakened versions of the SHA-3 candidate BLAKE. In difference to BLAKE, the BLOKE hash function does not permute the message words and constants in the round computation of the compression function, and BRAKE additionally removes feedforward and zeroes the constants used in each round of the compression function...

The downstream effector of PI3K, Akt, is frequently hyperactivated in human cancers. A critical downstream effector of Akt, which contributes to tumorigenesis, is mTOR. In the PI3K/Akt/mTOR pathway, Akt is flanked by two tumor suppressors: PTEN, acting as a brake upstream of Akt, and TSC1/TSC2 heterodimer, acting as a brake downstream of Akt and upstream of mTOR. In the absence of the TSC1/TSC2...

The sustainable exploitation of raw materials, with improved safety and increased productivity, is closely linked to the development mechanical mining installations. Mine hoists are designed for transport material, equipment personnel between mine surface underground. hoist braking system paramount importance in its safe operation. Thus, both drum disc brake systems, temperature friction surfac...

Brake fluid is a mixture of different Glycol derivatives which are poisoning and their ingestion triggers significant CNS symptoms, severe metabolic acidosis, cardiac, pulmonary, and renal failure. Here in this study, a case is reported who had been ingested 150mL of brake fluid for suicidal attempt.

Metal-based ceramic composite laser cladding offers substantial compensations in enhancing brake disc surface characteristics. Laser was utilized to combine B4C powder (10–40%) with Ni 63 make Boron Carbide (B4C)/Nickel coatings. For the subsequent experiments, specimens were ground and polished. Bonding strength, fracture toughness, residual stress examined content. The morphologies checked us...
