The present study is aimed at investigating the cost assessment of incorporating waste plastic bottles in manufacture voided concrete slabs; assessing depth ratio vis-à-vis reduction energy consumption and CO2 emission obtained by evaluating impact on embodied emission. was conducted five types slab specimens made: (1) conventional solid specimens; (2) incorporated with 5% air-filled bottles; (...

The outdoor service robot which we call OSR-01 is presently under development intending for cleaning up urban areas by means of collecting discarded trash such as PET bottles, cans, plastic bags and so on. We, in this paper, describe the architecture of OSR-01 consisting of hardwares such as sensors, a manipulator, driving wheels, etc. for searching for and picking up trash, and softwares such ...

Platelet survival was determined using untreated and siliconed glass bottles and plastic bags (Fenwal) for collecting and storing blood. The platelets were tagged in vivo with P(32) in six polycythaemic patients undergoing treatment with P(32). The results showed that fresh ACD blood collected in untreated glass, siliconed glass, and plastic gave the same recovery of platelets in the recipients...

Several studies have shown that valved (metal or plastic) spacers and, even homemade spacers (made out of bottles and plastic cups), are equivalent to or more advantageous than nebulizers for the delivery of medication in acute asthma att...

A procedure for the preparation of clarified Pawpaw Juice was developed. About 750ml Pawpaw pulp was measured into 2 measuring cylinders A & B of capacity 1 litre heated to 40C, cooled to 20C. 30mls pectinase was added into cylinder A, while 30mls distilled water was added into cylinder B. Enzyme treated sample (A) was allowed to digest for 5hours after which it was heated to 90C for 15 minutes...

Contemporary approaches to biology often call for the high-throughput production of large amounts of numerous proteins for structural or functional studies. Even with the highly efficient protein expression systems developed in Escherichia coli, production of these proteins is laborious and time-consuming. We have simplified established protocols by the use of disposable culture vessels: common...

This paper examines the impact of two popular solid waste programs on the percent recycled of several different materials found in the residential solid waste stream. We examine a unique, national, household-level data set containing information on the percent recycled of five different materials: glass bottles, plastic bottles, aluminum, newspaper, and yard waste. We find that access to curbsi...
