Development of laminar flow control wing surface porous structure
It was concluded that the chordwise air collection method, which actually combines chordwise and spanwise air collection, is the best of the designs conceived up to this time for full chord laminar flow control (LFC). Its shallower ducting improved structural efficiency of the main wing box resulting in a reduction in wing weight, and it provided continuous support of the chordwise panel joints, better matching of suction and clearing airflow requirements, and simplified duct to suction source minifolding. Laminar flow control on both the upper and lower surfaces was previously reduced to LFC suction on the upper surface only, back to 85 percent chord. The study concludes that, in addition to reduced wing area and other practical advantages, this system would be lighter because of the increase in effective structural wing thickness
The gynecologic oncologist in academic departments : Report of survey
Now that the subspecialty of gynecologic oncology is well established within the specialty of obstetrics and gynecology, it seems timely to evaluate the pros and cons, the strengths and weaknesses of such a program as it interrelates with other programs in an academic department. A survey is presented which reflects the beliefs of both members and candidate members of the Society of Gynecologic Oncologists on such issues as gynecologic oncologists as chairmen of departments; teaching demands; time commitments to patient care and research in an academic institution; and surgical privileges for gastro-intestinal and urologic procedures in various hospitals. Financial and budgetary items are also discussed. Perspectives from three different points of view are presented as a discussion of the report of the survey.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/24676/1/0000095.pd
Endometrial cancer
Endometrial cancer is the most common gynecological
malignancy in well-developed countries.
Biologically and clinicopathologically,
endometrial carcinomas are divided into two
types: type 1 or estrogen-dependent carcinomas
and type 2 or estrogen-independent carcinomas.
Type 1 cancers correspond mainly to endometrioid
carcinomas and account for approximately
90 % of endometrial cancers, whereas
type 2 cancers correspond to the majority of the
other histopathological subtypes.
The vast majority of endometrial cancers
present as abnormal vaginal bleedings in
postmenopausal women. Therefore, 75 % of
cancers are diagnosed at an early stage, which
makes the overall prognosis favorable.
The first diagnostic step to evaluate women
with an abnormal vaginal bleeding is the measurement
of the endometrial thickness with
transvaginal ultrasound. If endometrial thickening
or heterogeneity is confirmed, a biopsy
should be performed to establish a definite
histopathological diagnosis.
Magnetic resonance imaging is not considered
in the International Federation of Gynaecology
and Obstetrics staging system. Nonetheless it
plays a relevant role in the preoperative staging of
endometrial carcinoma, helping to define the best
therapeutic management. Moreover, it is important
in the diagnosis of treatment complications,
in the surveillance of therapy response, and in the
assessment of recurrent disease.info:eu-repo/semantics/publishedVersio
