Effect of calcium fluoride additions on the sintering of magnesium oxide

The effect of additions of calcium fluoride on the sintering of a refractory grade magnesium oxide fired under reducing conditions was studied. Specimens were formed at very low pressures to simulate compaction achieved in the jolt-pack technique, and at higher pressures commonly encountered in · powder-pressing of ware. Specimens were fired in an induction furnace and held for pre-determined periods at temperatures ranging from 1300°C. to 1900°C. Shrinkage, bulk density, and grain growth factor were determined and presented as a function of composition and temperature

The twenty-first-century HR organization

Like any value-creating staff function, HR departments should operate as a business within a business. Others have focused on the strategy and direction of HR departments. This article examines the next evolution for how HR department organization structure can deliver value based on two premises: (1) HR organization should be structurally aligned with the organization structure of the business and (2) because diversified/allied business models prevail, it is important to lay out the five roles and responsibilities of HR that respond to this organization model: service centers, corporate, centers of expertise, embedded HR, and operational HR. The article lays out the duties of each role, the relationship among these roles, and suggestions for implementing this new HR structure. © 2008 Wiley Periodicals, Inc.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/61309/1/20247_ftp.pd

Giant cystic pheochromocytoma with low risk of malignancy: A case report and literature teview

Giant pheochromocytomas are rare silent entities that do not present with the classical symptoms commonly seen in catecholamine-secreting tumors. In many cases they are accidentally discovered. The algorithm to diagnose a pheochromocytoma consists of biochemical evaluation and imaging of a retroperitoneal mass. The female patient in this case report presented with a palpable abdominal mass and was cured with surgical resection. She suffered no recurrence or complications on follow-up. The left retroperitoneal mass measured 27 × 18 × 12 cm and weighed 3,315 grams. Biochemical, radiological, and pathological examinations confirmed the diagnosis of a pheochromocytoma. In this paper, we report on our experience treating this patient and provide a summary of all giant pheochromocytomas greater than 10 cm reported to date in English language medical journals. Our patient’s giant cystic pheochromocytoma was the fourth heaviest and fifth largest maximal diameter identified using our literature search criteria. Additionally, this tumor had the largest maximal diameter of all histologically confirmed benign/low metastatic risk pheochromocytomas. Giant cystic pheochromocytomas are rare entities requiring clinical suspicion coupled with strategic diagnostic evaluation to confirm the diagnosis
