A 75-year-old woman underwent transthoracic CT-guided cutting-needle biopsy of a 5 5-cm mass of the superior segment of the left lower lobe and had an episode of recent hemoptysis. She had been ill for 3 months with dyspnea, cough, and intermittent sputum production. Chest radiographs revealed a persistent left lower lobe alveolar opacification believed to be pneumonia; however, the patient had...

Abstract In power systems, busbars connect important components such as generators, transmission lines, and loads. A typical fault occurrence on the busbar may result in isolation of faulty sections from other normally operating parts system resulting differential protection operation. Although main busbars' scheme is protection, its operation significantly affected by magnetic saturation curre...

the simultaneous flow of oil and water in porous media is described by relative permeability curves, mainly derived from laboratory experiments. relative permeability is of paramount importance in predicting reservoir production performance and drive mechanisms and its value depends largely on the volume fraction of fluids present in the test samples. nowadays x-ray scanners are one of the most...

ABSTRACT This study aimed to evaluate and compare the acute response, due semi-immersive virtual reality (VR) conventional therapies (CT), of hemodynamic parameters in hospitalized individuals admitted an emergency unity for heart failure (HF). is a viability with 11 subjected sessions without VR. At CT, stretching, active or active-assisted exercises, fractional inspiration were performed. In ...

PURPOSE To describe the CT and MR characteristics of intraocular silicone oil (polydimethylsiloxane), which is used with increasing frequency to treat complicated retinal detachments. METHODS CT was performed on a silicone oil/water phantom and on a patient with retinal detachments secondary to cytomegalovirus retinitis, treated by bilateral intraocular injections of silicone oil. CT appearan...

Abstract—Current transformers are an integral part of power system because it provides a proportional safe amount of current for protection and measurement applications. However, when the power system experiences an abnormal situation leading to huge current flow, then this huge current is proportionally injected to the protection and metering circuit. Since the protection and metering equipmen...

In bacteria, the DnaG primase is responsible for synthesis of short RNA primers used to initiate chain extension by replicative DNA polymerase(s) during chromosomal replication. Among the proteins with which Escherichia coli DnaG interacts is the single-stranded DNA-binding protein, SSB. The C-terminal hexapeptide motif of SSB (DDDIPF; SSB-Ct) is highly conserved and is known to engage in essen...

Rat chorda tympani (CT) responses to NH4Cl, ammonium acetate (NH4Ac), and ammonium hippurate (NH4Hp) were obtained during simultaneous current and voltage clamping of the lingual field potential. Although functional and developmental similarities for gustation have been reported for NH4+ and K+ salts, we report here that significant differences are discernible in the CT responses to both salts....
