INTRODUCTION Maternal HIV infection and related co-morbidities may have two outstanding consequences to fetal health: mother-to-child transmission (MTCT) and adverse perinatal outcomes. After Brazilian success in reducing MTCT, the attention must now be diverted to the potentially increased risk for preterm birth (PTB) and intrauterine fetal growth restriction (IUGR). OBJECTIVE To determine t...

The similarity, attraction, and compromise effects warrant specific investigation in multi-attribute decision making. To examine these effects concurrently, we assigned 145 undergraduates to three context effect conditions. They were requested to solve 20 hypothetical purchase problems that had three alternatives described along two attribute dimensions. We measured their choices, confidence ra...

Dholavira’s elaborate town-planning rests on the conscious use of specific proportions for its successive enclosures. Those proportions combined with the city’s dimensions allow us to calculate precisely the unit of length used for the fortifications, to relate it to the Lothal ivory scale, and to work out potential subunits. Both proportions and units receive overwhelming confirmation from str...

the strength of concrete is a function of the proportions of the constituent materials, namely, cement, water, fine and coarse aggregates. the conventional methods used to determine the mix proportions that will yield the desired strength, are laborious, time consuming and expensive. in this paper, a mathematical method based on modified regression theory is formulated for the prediction of con...

A mathematical model of the respiratory system is introduced in this study. Geometrical dimensions of the respiratory system were used to compute the acoustic properties of the respiratory system using the electro-acoustic analogy. The effect of the geometrical proportions of the respiratory system is observed in the paper. Keywords—Electro-acoustic analogy, total lung impedance, mechanical par...
