Catalytic Ketonization over Oxide Catalysts (Part XIV): The Ketonization and Cross-Ketonization of Anhydrides, Substituted Acids and Esters.

A series of 20 wt.% MO/S catalysts (where M = Ce, Mn or Zr and S = SiO or AlO) were prepared using various precursors of the active phases. The resulting catalysts were characterized using different methods (XRD, TPR and S).

Broadband stimulated Raman microscopy with 0.1 ms pixel acquisition time.

Femtosecond stimulated Raman microscopy (FSRM) is a nonlinear technique for rapid broadband Raman imaging. It utilizes a few femtosecond probe pulse and a narrow bandwidth pump pulse. Using a fast (20 kHz) multi-channel detector, stimulated Raman spectra can be recorded with an acquisition time as short as 0.

[Pulmonary embolism in material from a general surgery clinic].

Fifty patients hospitalized in the years 1983-1989 with pulmonary embolisation are the subject of this review. There were 26 females (mean age 69 years) and 24 males (mean age 61 years). The main indications for hospitalization were: peritonitis, malignant neoplasms, and bowel obstruction.

[Case of a tumor of the cranio-cervical region].

The authors report a case of successfully removed neurolemmoma of the craniocervical region treated for 8 years as multiple sclerosis.

[Immediate and remote results of treatment of cerebellar astrocytoma].

Cerebellar astrocytoma accounted for 10% of all brain tumours treated at the Department of Neurosurgery, Medical Academy in Cracow in the years 1946 to 1968. It accounted for 16.6% of all gliomas, and 57% of subtentorial gliomas.
