INTRODUCTION Control of anchorage is a fundamental problem in orthodontics. Conventional means of controlling anchorage are characterized by potential disadvantages and inconveniences: visibility, compliance dependence, risk of undesirable side effects, and injury. Titanium implants have evolved as a potential clinical alternative in overcoming the limits(More)
Three, single-day nutritional surveys at weekly intervals were conducted in the general medical wards of an urban municipal teaching hospital. The techniques of nutritional assessment included anthropometric measures (weight/height, triceps skin fold, arm-muscle circumference, serum albumin, and hematocrit). The prevalence of protein-calorie malnutrition(More)
We examined the changes in the levels of indoleacetic acid (IAA), IAA esters, and a 22-kilodalton subunit auxin-binding protein (ABP1) in apical mesocotyl tissue of maize (Zea mays L.) during continuous red light (R) irradiation. These changes were compared with the kinetics of R-induced growth inhibition in the same tissue. Upon the onset of continuous(More)
Gastro-oesophageal reflux (GOR) is the regur-gitation of gastric contents into the oesoph-agus. It is alleged to be the cause of many clinical problems in premature infants, such as failure to thrive, apnoea, desaturation, brady-cardia, and stridor. 1 2 Twenty four hour oesophageal pH monitoring is currently regarded as the optimal method of diagnosing(More)
Successful manufacturing system designs must be capable of satisfying the strategic objectives of a company. There exist numerous tools to design manufacturing systems. Most frameworks, however, do not separate objectives from means. As a result, it is difficult to understand the interactions among different design objectives and solutions and to(More)

Simulation is used to verify the feasibility of the design of manufacturing cells. The cell design, which combines new and existing machines in a component manufacture, is presented, showing the difficulties that can result with such a system. Simply changing the layout (arranging machines into cells) could provide some benefits, but these benefits were(More)
A framework was created to analyze manufacturing systems and assess the impact of various practices on system performance. A literature review of Lean Manufacturing resulted in the discovery of significant gaps in two areas: (1) modeling the effects of implementing Lean Manufacturing using control theory principles, and (2) a design framework for building(More)
