William Henry Fry’s Leonora: the Italian connection
On 7 June 1845, the New York Herald published a letter by an ‘occasional correspondent’ from Philadelphia concerning William Henry Fry's first grand opera, Leonora, which premiered three days before at the Chestnut Street Theatre. The letter contained the following remark:All were delighted with the music, it was so much like an old acquaintance in a new coat; indeed some of ‘the cognoscenti’ said that it was a warm ‘hash’ of Bellini, with a cold shoulder of ‘Rossini,’ and a handful of ‘Auber’ salt – whilst others congratulated Mr. Fry upon his opera being so much like Norma
Open and / or laparoscopic surgical treatment of liver hydatic cysts
Hydatid disease is a severe parasitic disease with a widely ranging distribution. In the human being the liver is the most frequent organ affected. 1 The treatment should be individualized to the morphology, size, number and location of the cysts, that is why a variety of surgical operations have been advocated from complete resection like total pericystectomy or partial hepatectomy to laparoscopy to a minimally invasive procedures like percutaneous aspiration of cysts to conservative drug therapy. 3-4 This study compares laparoscopic versus open management of the hydatid cyst of liver the surgical approach to liver echinococcosis is still a controversial issue and shows our results of surgical treatment of liver hydatid cysts during a 3-years period
Choosing an allograft or autograft in orthopedic surgeries for athletes
Athletes and their doctors have the choice of using an allograft or autograft in reconstruction surgeries. The purpose of this study is to see if there is a difference in the healing mechanism and surgical outcome in using an allograft or autograft during orthopedic surgical procedures, as well as to analyze graft rejection and disease transmission through donor tissue.
Doctors and athletic trainers were interviewed in order to learn about the healing mechanisms and advantages and disadvantages of allografts and autografts in order to conclude if one was better than the other. College level athletes on different sports teams were given a questionnaire that asked questions on the surgical procedure they got and whether or not the surgeon used an allograft or autograft. Specific questions relating to recovery time, stability, and overall function of the area of surgery were asked in order to analyze the outcome. The subjects were screened by choosing athletes with the same surgical reconstruction except one using an allograft and one using an autograft. The questions relating to the outcome of the surgery were compared in order to see if one produced a better outcome over the other. Athletes were found to have better success with autograft as predicted by doctors
Cognitive Moral Development and Real Estate Practitioners
In recent years, researchers in many organizational disciplines have begun to approach the study of ethics from a cognitive theoretical framework. This study has investigated the ethical reasoning of real estate practitioners using Kohlberg's cognitive moral development (CMD) approach, a potent theoretical concept with a considerable research literature. Using standardized measures of CMD on groups of Realtors® and controlling for level of education, the results of this study show that real estate practitioners compare favorably with other professional and societal groups. Further, when entered independently CMD was a significant indicator, along with education and experience, of success in real estate.
Explicit Solution to the Constant Radial Acceleration Problem
While the constant radial acceleration problem is known to be integrable and
has received some recent attention in an orbital mechanics context, a closed
form explicit solution, relating the state variables to a time parameter, has
eluded all researchers so far. It is here shown how such a solution exists and
is elegantly expressed in terms of the Weierstrass elliptic and related
functions. Previously known facts can be derived from the new explicit solution
and new insights are revealed.Comment: 19 pages, 6 figure
