The electronically steerable parasitic array radiator (ESPAR) has been proposed as an inexpensive device for spatial multiplexing in transmission via the so-called beamspace modulation. On the other hand, spatial multiplexing (SM) is well known to allow a linear increase of capacity in MIMO systems with the number of a... |
In 1217 patients with metastatic tumors of the brain (MTB) (13% of the 1935-1973 endocranial tumour statistics of the Neurosurgical Clinic, Bucharest) the lung was, found to be the most frequent location of the primary tumour in males and the breast in women. The MTBs preponderantly affected males (65%); the most frequ... |

This paper attempts to redress this situation by discussing the implementation of a Contrast Enhancement Material into manufacturing. Contrast Enhan... |
The determinants of species’ geographical ranges are the result of both abiotic and biotic factors. Among co‐occurring closely related species, some degree of differentiation in niche characteristics is assumed necessary to allow continued coexistence. As niche requirements are likely to show similarity or overlap, com... |
Ultra wide band communication systems extensively rely on low resolution and Giga samples per second data converters. Moreover, technology scaling beyond 90 nm drastically complicates the design of the communication systems.

A I U'? 0g *# * ARECE un juego ilusorio!" says Avellaneda as the first act of Zorrilla's celebrated Romantic drama draws to a close (1.1.830).1 The "game" is the rivalry between Don Juan Tenorio and Don Luis Mejia as to which of the two, in the course of one year, can seduce more women and kill more men in duel. The ga... |
PURPOSE |
We studied prophylactic intravesical instillation of mitomycin C (MMC) and pirarubicin (THP) following transurethral resection of bladder tumor (TUR-Bt) for superficial bladder cancer. |
MATERIALS AND METHODS |
Forty-six evaluable patients were administered intravesically 20 mg of MMC dissolved in 20 ml saline on day 1 and 20 mg of THP dissolved 20 ml 5% dextrose on day 2. The patients were followed up by cystscopy and urinary cytology. Intravesical instillations were performed once a month and continued for 5 years. |
RESULTS |
The non-recurrence rates at 1, 3 and 5 years were 88.8%, 79.5% and 67.0%, respectively. No significant differences were observed between grade 1-2 and 3, male and female, and solitary and multiple tumors. Although the side effects were relatively mild, 6 patients were stopped intravesical instillation. |
CONCLUSIONS |
Because non-recurrence rates of our report is not better than previous reports with shorter treatment periods, intravesical MMC and THP instillation for 5 years is not beneficial to the patients with superficial bladder cancer.The Self-Enclosing God: John Chrysostom and Ephrem Syrus on divine self-limitation as gift of... |
In this thesis I study four fourth-century patristic texts based on the creation and fall accounts in Genesis 1–3. Two of them are in Syriac, poetry and a commentary by Ephrem Syrus, and two are in Greek, two sets of sermons or homilies by John Chrysostom. I demonstrate through a close engagement with the texts in thei... |
For boat dwellers, what does it mean to acquire a house on land? Does it mean, as many researchers and government officials in modern countries have assumed, a departure from the “harsh world on the water” to salvation on the “enticing world of the land”? Through presenting an ethnographic study of the history of the l... |
Measuring the nuclear magnetic resonance spectra of low-gamma heteronuclei such as 15N constitutes an important analytical tool for the characterization of molecular structure and dynamics. The reduced resonance frequencies and magnetic moments of these heteronuclei, however, make the sensitivity of this kind of spectr... |

Cortactin is a cytoskeletal actin‐binding protein that is upregulated in several types of metastatic cancers. Standard purification of cortactin from E. coli involves expression of the protein as a His‐tagged protein followed by affinity purification with nickel resin. This purification is sometimes followed by anion e... |
BACKGROUND |
Tests and treatments that are not supported by evidence and could expose patients to unnecessary harm, referred to here as low-value clinical practices, consume up to 30% of health care resources. Choosing Wisely and other organizations have published lists of clinical practices to be avoided. However, few apply to inj... |
METHODS |
We conducted a scoping review targeting articles, reviews and guidelines that identified low-value clinical practices specific to injury populations. Thirty-six experts rated clinical practices on a five-point Likert scale from clearly low value to clearly beneficial. Clinical practices reported as low value by at leas... |
RESULTS |
Of 50,695 citations, 815 studies were included and led to the identification of 150 clinical practices. Of these, 63 were considered candidates for low-value injury care; 33 in the emergency room, 9 in trauma surgery, 15 in the intensive care unit, and 5 in orthopedics. We also identified 87 "gray zone" practices, whic... |
CONCLUSION |
We identified 63 low-value clinical practices in acute injury care that are supported by empirical evidence and expert opinion. Conditional on future research, they represent potential targets for guidelines, overuse metrics and de-implementation interventions. We also identified 87 "gray zone" practices, which may be ... |

Today, monuments and archaeological sites are often specific targets for violence. But rather than casting this as either collateral damage or the result of ignorance and incivility, it can be argued that the material world, in all its widely varied forms, is enmeshed in conflict and violence. This can be better unders... |
