One of the principal goals guiding unit-ops technology development is that of reducing the cyclical or batch character of mining, making a mine operate more like a refinery. With few exceptions, unit-ops technologies in use today at mine sites in the United States will be in use in 2020. Technology changes that are being implemented are incremental and typically focus on increasing batch size, ...

Everyone is ready to lead ethics classes and workshops—even undergraduates. One of mine recently asked me if I would agree to supervise an independent study in which she planned to design an ethics curriculum for middle-school and high-school students. “Maybe we could even take it down to elementary-school level,” she effused. This bright young woman earnestly believed that if people in low-inc...

It is always interesting to read what one has written many years ago. In this case the paper was initially given as an invited lecture to the American Association of Physics Teachers, the Millikan lecture. Then it was reprinted with several other papers of mine in Robert Taylor’s book, (The Computer in School: Tutor, Tool, Tutee, 1980) in the section that discusses the use of the computer as a ...

The TIRAMISU project aims at providing the foundation for a global toolbox that will cover the main mine action activities, from the survey of large areas to the actual disposal of explosive hazards, including mine risk education and training tools. After a short description of some tools, particular emphasis will be given to the topics proposed by the VALLON Workshop, namely the development of...

No single mine sensor has the potential to increase the probability of detection and decrease false alarm rates for all types of mines under the wide variety of environmental conditions in which mines exist. As is clear from the previous chapter, each innovative method is subject to limitations under certain conditions of environment and mine type. Thus it is unlikely that any one technology wi...

all to patients receiving additional VP16. Nadir neutrophil counts fell below 0.5x109/L in 42% of the single agent group and 69% of the two agent group. There were no documented bacteraemias. Nadir platelet count fell below 50x109/L in 6 cases (combined therapy); only one platelet transfusion was required, for a minor bleeding episode. There were no episodes of frank haematuria. The higher dose...

BACKGROUND This study aimed to assess the treatment outcomes of ifosphamide, mesna, etoposide, and prednisolone (IMEP) combination regimen as a front-line chemotherapy in patients with peripheral T-cell lymphomas (PTCLs). METHODS Clinical data of 38 newly diagnosed PTCLs patients who underwent IMEP at Busan Paik Hospital from January 2002 to December 2013 were retrospectively analyzed. RESU...

Neuroblastoma is the most common extracranial solid malignancy in children but rarely described in adults, being 10% of all cases diagnosed after the first decade of life. We report a 23 year-old black woman with a mass at paravertebral region of T3-T5, multiple lesions in vertebral bodies and expanding skull-brain lesion at the right parietal region. Immunohistochemical analysis (negative for ...

Cyclophosphamide-induced bladder malignancy is a well-known entity mediated by its metabolic product, acrolein. There is a significant association between the incidence of hemorrhagic cystitis during treatment and the later development of malignancies. We report a case of multifocal urothelial carcinoma occurring in a patient treated with ifosfamide 19 years ago. No case report of ifosfamide-in...
