BACKGROUND The optimal treatment for femoral fractures in children is controversial. The purpose of this study was to compare the results of Rush pin fixation with those of conservative treatment, and to evaluate the sequels of growth plate injury by internal fixation. METHODS Eighteen femoral shaft fractures in 17 children who had concomitant head injury or multiple traumas were treated surg...

OBJECTIVE To develop a distance measure based methodology to support the morphological evaluation of high grade prostatic intraepithelial neoplasia (PIN), a direct precursor of prostate cancer. METHODS Eight morphological and cellular features were analysed in 20 cases of high grade PIN found in radical prostatectomy specimens from patients with adenocarcinoma. The diagnostic distance was eva...

This paper discussed the synthesis of LTA zeolite from Pinheiro clay (PIN) aiming for adsorption CO2. To obtain LTA-PIN zeolite, PIN was submitted to acid treatment, followed by calcination and hydrothermal treatment. These treatments promoted reorganization crystalline structure PIN, leading with 95.79% purity confirmed XRD, SEM, XRF, FTIR results. The performance similar one standard zeolite....

A new high-speed pin-on-bar type tribometer has been developed to study the variation of friction coefficient with respect local thermomechanical contact conditions between tool and workpiece when drilling C45 steel. The forces temperatures are measured over a range pin indent depths sliding velocities in open closed loop tribo-systems. tribometer’s ability recreate is demonstrated induced surf...

Contactless card payments are being introduced around the world allowing customers to use a card to pay for small purchases by simply placing the card onto the Point of Sale terminal. Contactless transactions do not require verification of the cardholder’s PIN. However our research has found the redundant verify PIN functionality is present on the most commonly issued contactless credit and deb...

The pin-to-pin electrostatic discharge (ESD) stress was one of the most critical ESD events for differential input pads. The pin-to-pin ESD issue for a differential low-noise amplifier (LNA) was studied in this work. A new ESD protection scheme for differential input pads, which was realized with cross-coupled siliconcontrolled rectifier (SCR), was proposed to protect the differential LNA. The ...

Removing a broken guide wire is difficult and challenging. This article reports a method that was used to successfully remove a broken guide wire in 3 patients who underwent operative treatment for intertrochanteric fractures of the femur. Under general anesthesia, the first patient was placed on the orthopedic fracture table, and closed reduction of the hip fracture was performed under the ima...

A time-domain-reflectometry Smith-chart display is demonstrated to be a valuable diagnostic tool in a variety of situations in time-domain-reflectometry dielectric spectroscopy. A relative reflection coefficient is formed by dividing the Laplace transform of the reflected sample transient by the Laplace transform of the empty-sensor transient and displaying in the complex plane, with the approx...

Puroindoline (Pina and Pinb) genes control grain texture or hardness in wheat. Wild-type/soft alleles lead to softer grain while a mutation in one or both of these genes results in a hard grain. Variation in hardness in genotypes with identical Pin alleles (wild-type or mutant) is known but the molecular basis of this is not known. We now report the identification of wheat genotypes with hard g...
