This study deals with the cumulative pitch variations in DIN male contacts. A connector provides a separable interface between two subsystems of an electronic system. DIN is a series of connector which stands for Deutsch Institut fur Normung. They are used for applications like switching, transmission, radio base stations, control units and machines. Connector manufacturing involves stamping, m...

BACKGROUND The reduction of instrumental dead space is a recognized approach to preventing ventilation-induced lung injury in premature infants. However, there are no published data regarding the effectiveness of instrumental dead-space reduction in endotracheal tube (ETT) connectors. We tested the impact of the Y-piece/ETT connector pairs with reduced instrumental dead space on CO2 elimination...

The digital part of the radiometer project is broken into several stages of development (Digital IF, APB, FFT, etc) and it is important to be able to capture results from each stage. It is of equal importance that each stage be capable of interfacing to the proceeding stage. Consequently a standard interface was developed using a high density 68-pin SCSI3 connector. This is the same connector w...

During assembly, bacterial virus phi29 utilizes a motor to insert genomic DNA into a preformed protein shell called the procapsid. The motor contains one twelve-subunit connector with a 3.6 nm central channel for DNA transportation, six viral-encoded RNA (packaging RNA or pRNA) and a protein, gp16, with unknown stoichiometry. Recent DNA-packaging models proposed that the 5-fold procapsid vertex...

Structurally segregated and functionally specialized regions of the human cerebral cortex are interconnected by a dense network of cortico-cortical axonal pathways. By using diffusion spectrum imaging, we noninvasively mapped these pathways within and across cortical hemispheres in individual human participants. An analysis of the resulting large-scale structural brain networks reveals a struct...

OBJECTIVE A groove technique for securing an electrode connector was described as an alternative surgical technique in deep brain stimulation (DBS) surgery to avoid electrode connector-related complications, such as skin erosion, infection, and migration. METHODS We retrospectively reviewed 109 patients undergoing one of two techniques; the standard technique (52 patients using 104 electrodes...

the aim of this study was to determine the effect of trenched zirconia bar on the von mises stress distribution of ips -empress ii core ceramics.the three-dimensional model including a three-unit bridge from the second premolar to the second molar was designed. the model was reinforced with zirconia bar (zb), zirconia bar with vertical trench (vzb) and zirconia bar with horizontal trench (hzb) ...

INTRODUCTION Before IS-1 (3.2 mm) standardization of pacemaker leads and connectors, 5/6 mm connector ports accomodated 5mm or 6mm diameter lead connector pins. CASE REPORT A patient with sick sinus syndrome underwent implantation of a 5mm unipolar atrial lead, mated to a 5/6mm connector port Medtronic Spectrax Sx 5985 pacemaker. Pulse generator reached ERI in 2006, with change out to a Medtr...

HAMP domains are approximately 50-residue motifs, found in many bacterial signaling proteins, that consist of two amphiphilic helices joined by a nonhelical connector segment. The HAMP domain of Tsr, the serine chemoreceptor of Escherichia coli, receives transmembrane input signals from the periplasmic serine binding domain and in turn modulates output signals from the Tsr kinase control domain...

UNLABELLED Zirconia is currently used as a framework material for posterior all-ceramic bridges. While the majority of research efforts have focused on the microstructure and corresponding mechanical properties of this material, clinical fractures appear to be largely associated with the appliance geometry. OBJECTIVE The objective of this study was to estimate the maximum stress concentration...
