Undesirable burrs are created in most of the machining processes. A burr is a plastically deformed material that remains attached at the workpiece edges after machining, and must be removed for making the parts to function effectively. The main objective of the present work is to explore the suitable condition to obtain minimum or negligible burr around the edge of a machined product at wet con...

Entrapment of the burr within calcified lesion is an uncommon, but serious complication during rotational atherectomy and usually needs surgical retrieval. We report a case series of this complication and also review the possible mechanisms, such as kokesi phenomenon or insufficient pecking motion with decreased rotational speed. We also review the potential techniques ever proposed to rescue t...

Deep brain stimulation (DBS) surgery typically involves placement of a single lead through a burr hole, either unilaterally or bilaterally. Rare indications, however, call for placement of 2 ipsilateral leads. To date, there have been no technical descriptions of how best to secure dual ipsilateral leads to the skull. We describe a method of placing and securing 2 ipsilateral DBS leads through ...

The essentiality of the unsaturated fatty acids, linoleic and linolenic, was described by Burr and Burr in a series of papers from the late 1920’s to the early 1930’s (Burr et al., 1932). They are incorporated into membranes as such, and are precursors for other unsaturated fatty acids that are key for metabolic regulation and cell membrane function and are essential to life for all mammals. Pr...

A new modified version of the Bagdonavičius-Nikulin goodness-of-fit test statistic is presented for validity right censor case under double Burr type X distribution. The maximum likelihood estimation method in censored data used and applied. Simulations via algorithm Barzilai-Borwein performed assessing method. Another simulation study testing null hypothesis Bagdonavičius Nikulin statistical t...

In a series of previous papers, it has been shown that the onset of an atypical growth in mice produces significant changes in the electrodynamic fields. This was true in the case of spontaneous tumors (Burr, Smith, and Strong'), in tumors induced by methylcolanthrene (Burr, Strong, and Smith2), and tumors induced by external application of benzpyrene (Burr, Smith, and Strong3). In all cases th...

The Burr type XII has been studied for various applications of lifetime modelings. However, control charts related to the Burr type XII percentiles have not been seen in the literature. In this paper, three control charts for the Burr type XII percentiles are investigated. An extensive Monte Carlo simulation study is conducted to compare among the Shewhart-type chart, and parametric bootstrap c...
