Developments on Constitutive Material Model for Architectural Soda-Lime Silicate (SLS) Glass and Evaluation of Key Modelling Parameters.

Architectural soda-lime silicate glass (SLS) is increasingly taking on complex shapes that require more detailed numerical analysis. Glass modeling is a thoroughly described topic with validated constitutive models. However, these models require a number of precise material parameters for SLS glass, and these are very sensitive to changes in glass composition.

[Ultrasonographic investigations in diagnosis of congenital malformations of epididymis in cases of azoospermia].

Between 1984-1991 in 28 patients referred for the surgical treatment for the reason of obstruction of epididymis outlet ducts there was a suspicion of a congenital epididymis malformation put after the physical examination. The ultrasound examination of the scrotum which was performed in all cases revealed the proper view of the epididymis in 5 cases, the proper head of the epididymis with the broad tubules and the lack of the corpus and cauda in 19 cases and in 4 cases the residual head of the epididymis located in region of the upper pole of the testis. Intraoperative findings were consistent with the ultrasound results in 75.

[Congenital malformations of the epididymis and vas deferens as reasons for male infertility].

Between 1966-1991 330 patients where the semen analysis revealed azoospermia and the histopathological examination of biopsy specimen of testis shown retained spermatogenesis and spermiogenesis underwent the surgical intervention. In 80% of cases congenital malformations of epididymis and vas deferens were found. The types of malformations detected during the surgery are discussed.

[The puzzle of spontaneous regression of pulmonary metastasis of renal carcinoma (after many years of observing the patient)].

A case of spontaneous of pulmonary metastases of renal carcinoma RCC with 16-years follow-up was presented. Based on review of literature, current opinions on spontaneous regression of the pulmonary metastases in RCC after nephrectomy are discussed.

[Preliminary clinical evaluation of systemic chemotherapy of invasive cancer of the bladder by the CMV protocol].

The authors discuss the results of preliminary clinical trials with chemotherapy with CMV (cisplatin, methotrexate, vinblastine) in the group of 17 patients with the infiltrating cancer of the bladder. Chemotherapy was used as an element of the radical treatment (in 7 patients, i.e.
