Transfusion Error in the Gynecology Patient: A Case Review with Analysis

Emergency blood transfusion (EBT) is a life-saving intervention which also carries a significant risk of harm in the event of a transfusion reaction. Our chapter starts with a hypothetical case study of a gynecology patient who underwent emergent hysterectomy with severe hemorrhage managed with an emergency blood transfusion. During the aggressive resuscitation, the patient was inadvertently transfused with blood products that had been allocated for another patient. Through this clinical vignette, we review the operational aspects of an EBT and identify sources of transfusion-related errors. We emphasize best practices that can be implemented with the goal of improved patient safety. This chapter offers a concise, practical review of EBT for our readers

Transfusion Error in the Gynecology Patient: A Case Review with Analysis

Fonetik meliputi studi tentang suara. Dalam produksi suara, sebagian besar pembicara yang sama memiliki lafal yang berbeda. Cara pembicara menyadari bahwa fonem tunggal bermacam-macam, ini menyebabkan terjadinya fonetik khas diantara mereka. Fakta ini jelas ditunjukkan oleh orang Amerika, Indonesia, Italia, dan India, karena mereka adalah penutur asli dan non-asli bahasa Inggris. Akibatnya, penelitian ini menjawab masalah apa variasi fonetik dimiliki oleh penutur asli dan non-pribumi dan fonetik komparatif di dua. Penduduk asli dan non-asli penelitian ini adalah karakter dalam film 'Eat, Pray, Love'. Ini adalah film Amerika yang Melibatkan Karakter Bangsa Dari Berbeda negara, Mereka Apakah Inggris dan Indonesia, Italia, India dimana mereka memiliki kinerja fonetik, dengan cara yang berbeda dan tempat suara diartikulasikan sangat menonjol. Tujuan dari penelitian ini adalah untuk menggambarkan fonetik variasi yang digunakan karakter asli, menggambarkan fonetik variasi non karakter asli, dan untuk menemukan perbedaan dan persamaan fonetik variasi antara karakter asli dan non karakter asli. Desain penelitian ini adalah deskriptif kualitatif dan metode komparatif. Sumber data yang didapatnya dari film dalam bentuk suara semua kata yang dihasilkan oleh kedua kelompok, maka hanya suara kata-kata serupa dan suku terpilih sebagai data. Selain itu, proses analisa data memiliki beberap alangkah, menyalin suara, menyortir fonetik, mengklasifikasikan variasi fonetik tertentu, dan merumuskan persamaan dan perbedaan variasi fonetik dari dua jenis karakter. Hasil penelitian menunujukan bahwa fonetik variasi pada karakter asli terdapat voiced Alveolar fricative consonant, half-open back rounded vowel, Voiceless alveolar plosive consonant. Pada fonetik variasi dalam non karakter asli terdapat close front unrounded vowels, voiced alveolar approximant consonant, open front unrounded vowel, open back rounded vowel, open front unrounded vowel, produce open back rounded vowel, close front unrounded vowel, voiceless labiodental fricative, voiced labiodental fricative. Dan fonetik variasi karakter asli dan non karakter asliterdapat6 half open back rounded vowel, 4 half open central vowel, 4 close front unrounded vowel, 7 voiced alveolar fricative consonant, 2 voiced labiodental fricative dan voiceless labiodentals fricative consonant, 3 fricativevoiced alveolar approximant consonant, 1 voiceless velar plosive consonant, 3 voiceless dental fricative consonant, 3 voiceless alveolar plosive consonant yang ditemukanpada kata – kata sama yang diucapkan oleh karakter asli dan non asli dalam film “Eat, Pray, Love”. Saya menyadari bahwa variasi fonetik sangat penting dalam pelafalan bahasa Inggris. Dengan penuh harapan murid dapat mengerti fonetik variasi bagaimana melafalkan sebuah kata, dosen bahasa Inggris dapat mengajari mahasiswa mereka bagaimana melafalkan sebuah kata dengan baik. dan kepada peneliti lain dapat menggunakan penelitian ini untuk referensi lebih lanjut

Interferometric detection of a single vortex in a dilute Bose-Einstein condensate

Using two radio frequency pulses separated in time we perform an amplitude division interference experiment on a rubidium Bose-Einstein condensate. The presence of a quantized vortex, which is nucleated by stirring the condensate with a laser beam, is revealed by a dislocation in the fringe pattern.Comment: 4 pages, 4 figure

Generation and evolution of vortex-antivortex pairs in Bose-Einstein condensates

We propose a method for generating and controlling a spatially separated vortex--antivortex pair in a Bose-Einstein condensate trapped in a toroidal potential. Our simulations of the time dependent Gross-Pitaevskii equation show that in toroidal condensates vortex dynamics are different from the dynamics in the homogeneous case. Our numerical results agree well with analytical calculations using the image method. Our proposal offers an effective example of coherent generation and control of vortex dynamics in atomic condensates.Comment: 4 pages, 2 figure

Coherently Scattering Atoms from an Excited Bose-Einstein Condensate

We consider scattering atoms from a fully Bose-Einstein condensed gas. If we take these atoms to be identical to those in the Bose-Einstein condensate, this scattering process is to a large extent analogous to Andreev reflection from the interface between a superconducting and a normal metal. We determine the scattering wave function both in the absence and the presence of a vortex. Our results show a qualitative difference between these two cases that can be understood as due to an Aharonov-Bohm effect. It leads to the possibility to experimentally detect and study vortices in this way.Comment: 5 pages of ReVTeX and 2 postscript figure

High polarization photocathode R D at SLAC

This paper describes recent progress on the development of high polarization photocathodes for polarized electron sources. A strained InGaAs cathode has achieved a maximum electron-spin polarization of 71% and has demonstrated the strain enhancement of polarization for the first time. Strained GaAs cathodes have yielded polarizations as high as 90% with much higher quantum efficiency

Strain enhanced electron spin polarization observed in photoemision from InGaAs

Electron spin polarization in excess of 70% has been observed in photoemission from a 0.1 {mu}m-thick epitaxial layer of In{sub x}Ga{sub 1-x}As with x {approx} 0.13 grown on a GaAs substrate. Under these conditions, the epitaxial layer is expected to be highly strained by the 0.9% lattice mismatch, as confirmed by X-ray diffractometer measurements of the lattice parameter. The electron polarization and the quantum efficiency have been measured as a function of the excitation photon energy from 1.25 to 2.0 eV. A significant enhancement of the electron polarization occurs in the vicinity of 1.33 eV where the expected strain-induced level splitting permits optical excitation of a single band transition. Measurements made on a control sample of 1.14 {mu}m thickness, significantly larger than the critical thickness for pseudomorphic strain, show no polarization enhancement. These measurements represent the first observation of strain-enhanced electron spin polarization for photoemitted electrons. 7 refs., 3 figs
