The changes which occur in renal excretory function during pregnancy are discussed. The relationship between glomerular filtration rate and effective renal plasma flow is examined in the light of new serial data obtained under conditions of saline diuresis. Changes in the renal handling of nutrients and in the excretion of waste products during pregnancy are reviewed.

An automated system is described for the sensor-based precision docking and manipulation of large objects. Past work in the remote handling of large nuclear waste containers is extensible to the problems associated with the handling of large objects such as coils of flat steel in industry. Computer vision and ultrasonic proximity sensing as described here are used to control the precision docki...

We report a case of infectious endocarditis attributable to Legionella longbeachae. L. longbeachae is usually associated with lung infections. It is commonly found in composted waste wood products. L. longbeachae should be regarded as an agent of infectious endocarditis, notably in the context of gardening involving handling of potting soils.

Material handling is a loose loop in most assembly plants. Jiist-in-time (JIT) is a management philosophy that strives to eliminate sources of manufacturing waste by producing the right part in the right place at the right time. We propose to apply JIT principles to material handling in assembly plants. Material Kanbans are introduced as an effective means to control and balance the physical ma...

This study aimed to explore the perception healthcare sector teachers, students and graduates from two institutions of higher learning in Rio Grande do Sul, on the generation of waste from healthcare services. It used a qualitative research approach, performed with 13 teachers, 18 students and 12 healthcare professionals, who were collected through a focus group. The main results showed there i...

An assessment of the radiotoxicity of spent nuclear material and the fuel handling issues associated with plutonium (Pu) or transuranics (TRU) multi-recycling in PWRs using the CORAIL assembly concept has been performed. This necessitated the development of an analytical approach to solve directly for the equilibrium state of repeated recycle, including higher actinide content. The equilibrium ...

Printed Circuit Boards (PCBs) are an integral part of any electronic equipment. The growth of e-waste as endof-life electronic equipments at an exponential rate is producing large quantities of discarded PCBs. In India, current recycling and processing of PCBs is managed almost entirely by the informal sector or the unskilled labor (95%). The crude recycling activities cause irreversible health...

For a deep geological repository for spent nuclear fuel planned in Sweden, the safety assessment covers up to 1 million years. Climate scenarios range from high-end global warming for the coming 100 000 years, through deep permafrost, to large ice sheets during glacial conditions. In contrast, in an existing repository for short-lived waste the activity decays to low levels within a few tens of...
