Levee setback location and height are important issues in flood levee system design and modification. This paper derives an economic-engineering theory of the optimal trade-off of levee setback for height both for original and redesigned flood levees, demonstrating the interconnection of levee setback, height, costs and risks, and economically optimal design. These analyses assume stationary fl...

Objective. To investigate the factors affecting intraoperative hemorrhage and postoperative sequelae after orthognathic surgery. Materials and Methods. Eighty patients with mandibular prognathism underwent surgical mandibular setback with intraoral vertical ramus osteotomy (IVRO). The correlation between the blood loss volume and postoperative VAS with the gender, age, and operating time was as...

Secreting and nonsecreting hybridoma populations derived from the murine hybridoma cell line 167.4G5.3 were each grown in batch culture in low serum and serum-free media. Under serum-free conditions, a secreting population gained on a predominantly nonsecreting population and competed with the existing antibody-deficient cells effectively. It was found that this competition was sensitive to sta...

Supplemental water sprays were placed along the sides of a continuous mining machine to improve suppression and confinement of the dust cloud under the cutting boom to reduce downwind dust levels. Using a full-scale mock-up of a continuous mining machine, preliminary work showed that these side sprays improved suppression of the dust cloud and redistributed this cloud under the cutting head. Th...

OBJECTIVES To describe an alar cartilage-modifying technique aimed at decreasing nasal tip projection in cases with overdeveloped alar cartilages and to compare it with other deprojection techniques used to correct such deformity. DESIGN Selected case series. SETTINGS University and private practice settings in Alexandria, Egypt. PATIENTS Twenty patients presenting for rhinoplasty who had...

BACKGROUND The aim was to evaluate the long-term hard and soft tissue changes following mandibular advancement and setback surgeries. MATERIALS AND METHODS A total of 16 subjects each were selected who underwent bilateral sagittal split osteotomy mandibular advancement and mandibular setback groups. Pre-surgical (T1), immediate post-surgical (T2) and long-term post-surgical (T3) cephalograms ...
