The prototypical metal-insulator transition in VO at 340 K is from a high-temperature rutile phase to a low-temperature monoclinic phase. The lower symmetry of the monoclinic structure removes the degeneracy of the two equivalent directions of the tetragonal structure, giving rise to twin domains. Since formation of domain walls require energy most needle-like monoclinic single crystal are single-domain.

For Loewald the subject moves from past to present, in a therapeutic fashion, through the intervention of the analyst, a contemporary object. A redemption of time occurs in the internalized action of thought and dialogue.

This article presents a revisionary reading of Freud's Beyond the Pleasure Principle. Recognizing the power of Freud's meditation on a universal "death-drive" in living organisms, it argues that Freud makes a greater contribution by strengthening the compulsion to repeat to a form of figurative death. We recall that after shattering the presupposition of a universal pleasure principle, Freud demonstrates an equally strong pain-principle.

Materials And Methods: A standard flexible gastroscope is inserted into the ileal conduit. Guide wires are passed into the ureters under direct vision.
The crystal structure of benzoylacetone (1-phenyl-1,3-butanedione, C(10)H(10)O(2); P2(1)/c, Z = 4) has been determined at 300, 160 (both Mo Kalpha X-ray diffraction, XRD), 20 (lambda = 1.012 Å neutron diffraction, ND) and 8 K (Ag Kalpha XRD), to which should be added earlier structure determinations at 300 (Mo Kalpha XRD and ND, lambda = 0.983 Å) and 143 K (Mo Kalpha XRD).

Reactions may occur via contact with the skin and mucous membranes or from catheters treated with the antibacterial agent. Apart from implicating chlorguanide in immunoglobulin (Ig) E antibody-binding studies on serum from an anaphylactic patient, little work has been done on the molecular basis of recognition of the agent in sensitive subjects.

Objective: The aim of this study was to assess the roles of transrectal color Doppler and gray-scale sonography in revealing prostatic cancer, using biopsy as the reference standard.
Subjects And Methods: Two hundred fifty-six patients referred for urologic studies underwent transrectal sonography using gray-scale and color Doppler scanning. All abnormal areas shown on gray-scale or color Doppler sonography or both were targeted and biopsies were performed.

Impotence is a clinical problem that patients and doctors are becoming more prepared to discuss. To advise patients with confidence a knowledge of causes, investigations and treatments is necessary. The treatment options include sex counseling, intracorporeal injection, external vacuum devices and penile implants.

The penile prosthesis has become established as a mode of therapy for organic and chronic psychogenic impotence. The Jonas type of penile prosthesis has been implanted into 10 patients and has achieved both functional success and excellent acceptance by the partner. Mechanical and pathological complications have a very low incidence.
