Applications of aluminium alloys

Bakalářská práce se zabývá základním přehledem hliníku a jeho slitin. Pojednává o vlastnostech primárního hliníku, jeho výroby i výhodami pramenící ze zpracování sekundárního hliníku. Práce se dále zabývá slitinami jako takovými. Popisuje základní legující prvky, jejich rozdělení včetně jejich specifických vlastností. Uvádí také dopady tepelného zpracování a povrchových úprav na vlastnosti slitin. V neposlední řadě se práce zaobírá aplikovatelností hliníku a jeho slitin v nejrůznějších oblastech průmyslu. Stručně charakterizuje danou problematiku konkrétních aplikací a uvádí výhody i nevýhody pramenící z jejich použití.This bachelor thesis deals with basic overview of aluminum and its alloys. It deals with properties of primary aluminum, its production and the benefits resulting from the processing of secondary aluminum. The thesis also discusses aluminum alloys as well. It describes the basic alloying elements, their distribution and their specific properties. It also mentions the effects of the heat and surface treatments on the properties of the alloys. Finally, the thesis deals with applicability of aluminum and its alloys in various industries. Briefly describes the issue of specific applications and provides advantages and disadvantages arising from their use.

Incarcerated Femoral Hernia

Careful analysis of 12 complicated cases of incarcerated femoral hernia gives clues toward the correct diagnosis of this problem. Knowledge of the symptoms can prevent dangerous delays in undertaking urgently-needed surgical repair. The unique anatomy involved requires careful clinical examination but surgery should not await x-ray studies

Echinococcosis of the Liver: Report of a Case

Echinococcosis of the liver is so rare in our practice that the case presented is the only one documented in the records of Henry Ford Hospital. The massive enlargement of the liver required surgical intervention. Marsupialization was the treatment of choice. In spite of post-operative complications, the patient made a satisfactory recovery

Epidermoid Carcinoma Arising in an Epidermal Inclusion Cyst

Mostly because of adequate early treatment, large epidermoid carcinomas are not frequently seen today. The case which we documented is unusual because of the huge size of the tumor and the resulting deformity. The photographs illustrate the pre-operative and post-operative appearance. The fact that these tumors can reach enormous size and become malignant bears repeating. Radical excision and skin grafting, we believe, resulted in a cure for this patient. Incidentally, there was a great change in her mental outlook after the removal of this tumor

Posttraumatic Hernia of the Bladder

Fractures of the pelvis occur commonly in patients who are involved in high speed vehicle accidents or who fall from a substantial height. Fortunately, with improved surgical management, these patients usually recover not only from the pelvic fractures but from associated visceral injuries as well. Some survivors of pelvic fractures subsequently develop unusual hernias. We report the case of a man who developed hernia of the urinary bladder following pelvic fracture. Two previous operations had failed to eliminate his hernia. We describe the technique of repair used successfully in this case and review similar reported cases. Surgeons who care for traumatized patients must be alert to the possible presence of a pelvic fracture whenever pelvic laparotomy is performed for visceral injury. Reduction of the fracture and internal fixation are necessary to prevent posttraumatic hernia

The Bacteriology of the Biliary Tract: A preliminary report.

The bacterial flora of acute biliary tract disease has not been completely elucidated. The organisms identified most often were coliforms. Anaerobic culture technics were not precise enough to provide proper identification. In a 12-month study of 250 patients operated upon for inflammatory gallbladder disease, culture specimens were collected in a most strict and rigorous fashion. It was hoped that a more exact understanding of the relationship between bacteria and inflammatory biliary tract disease might be appreciated. Important technics were developed for gathering specimens, delivery to the laboratory and culturing. More meaningful results are to be expected In the future
