Differing from the published documents on effect of texture distributions sliding tribo-pairs their friction and wear properties, this study introduced eight patterns to reveal influence different pits tribological behavior textured rolling element bearings with nylon cages under dry condition, namely: Outside-1/4 (OS1/4), Outside-1/2 (OS1/2), Outside-3/4 (OS3/4), Inside-1/4 (IS1/4), Inside-1/2...

Commercial production of eggs and egg products requires the washing of eggs to remove urinary-fecal material and broken egg residue. In the case of one Ohio farming facility, 1.6 million birds produce 1.4 million eggs per day, using approximately 50 mL of wash water/egg or approximately 70,000 L per day. The aqueous waste stream was evaluated for estrogenicity to determine if potential for endo...

During laundering, synthetic textiles (polyester, polyamide, etc.) can release small fiber debris with a length of <5 mm. These are type microplastics (MPs), usually referred to as microfibers (MFs), which considered high-concern pollutants due their continuous and cumulative entrance into the environment. Currently, far we know, there no feasible alternatives remove them. In this work, four...

Cases infectious diseases continue to be recorded among medical personnel BFM, requires prevention infection during activities. process legal regulation BFM activities terms compliance with sanitary and hygienic measures ensu...

• Multi-layer MXenes were used as solid lubricants coatings for rolling bearings. Comparison with molybdenum disulfide (MoS 2 ) and diamond-like carbon (DLC) coatings. Bearing washer wear was substantially reduced by MXene Transfer film formation verified on secondary contacts (rolling elements/cage pockets). Service life extension 30 55% compared to MoS DLC, respectively. Two-dimensional (2D) ...

Ethnomathematics can empirically improve the cognitive abilities of students in elementary and secondary schools. However, undergraduate study, there are still limited studies on integrating ethnomathematics learning resources. This study aims to apply interpolation modelling polynomial functions integral volume shape Buginese Makassarese traditional foods. Furthermore, it be used by as relevan...

Abstract Multi-material bulk metal components allow for a resource efficient and functionally structured component design, with load adaptation achieved in certain functional areas by using similar dissimilar material combinations. One possibility the production of hybrid is Tailored Forming, which pre-joined semi-finished products are hot-formed novel process chains. By means properties joinin...

This study provides a comprehensive, high-resolution structural analysis of the central-pair microtubule apparatus of sperm flagella. It describes the arrangement of several microtubule-associated "sheath" components and suggests, contrary to previous thinking, that microtubules are structurally asymmetric. The two microtubules of the central pair are different in several respects: the C2 tubul...

Objective: The present study was carried out to examine the efficacy of psychoneurotherapy (PNT) on reducing symptoms severity in treatment-naïve patients with obsessive-compulsive washing. This study evaluated a new form of psychotherapy based on neurobiological model of obsessive-compulsive disorder (OCD).  Methods: The study was conducted as a quasi-experimental research. The stat...
