Causal Analysis of Damage of a Cover

In this article, the causes of damage of a cover were investigated by metallographic and fractographic analysis. The component part was made from non-alloy quality steel for cold forming DC04. The failure occurred during high temperature pulsation (90 °C, 7b, 1 Hz) after 180,000 cycles. This component part was fabricated by deep drawing. After this process’s step, outlets were soldered at 1100 °C/5 min. to this part and then whole component part was coated using method without any specification. The coating layer was formed of Zn-Ni. The last step in this process was hemming where all component parts were assembled together. This case study was solved using light and scanning electron microscopy. The chemical composition was detected by energy dispersive X-ray analysis.

Recurrent vaginal discharge causing by retained foetal bones in a bitch: a case report

An 18-month-year old mixed breed bitch was referred to the Animal Hospital of Adnan Menderes University suffering from recurrent serous vaginal discharge for two months. Her temperature, pulsation, appetite and also hematologic parameters were normal. Transabdominal ultrasound scan revealed fullness in bifurcation uteri and bright echoes suggestive of bone caudally. During hysterotomy, retained foetal bones were observed in corpus uteri but not removed as they had become embedded in the uterine wall. Therapy of this case was completed with ovariohysterectomy operation. No aerobic bacteria were isolated from both samples taken from the vaginal discharge and retained foetal bones in the uterine cavity. Although rare, veterinary clinicians should be aware of this problem also in young bitches with no general symptoms and are well advised to use genital ultrasonography in examinations.
