An Improved Syringe for Injecting Precise Amounts
The method described by Rosenau 1 for injecting precise amounts of fluids into animals is excellent. In the practical application of this method certain difficulties have however been encountered, which, it is believed, can be overcome by improvements in the syringe herein described. The time reqtfired for removing the bulb of and measuring the salt solution into the syringe to wash i t out, af...
متن کاملThe syringe gap: an assessment of sterile syringe need and acquisition among syringe exchange program participants in New York City
BACKGROUND Programmatic data from New York City syringe exchange programs suggest that many clients visit the programs infrequently and take few syringes per transaction, while separate survey data from individuals using these programs indicate that frequent injecting - at least daily - is common. Together, these data suggest a possible "syringe gap" between the number of injections performed b...
متن کاملAn Improved Strategy for Exploring a Grid Polygon
We study the problem of exploring a simple grid polygon using a mobile robot. The robot starts from a location which is adjacent to the boundary of the polygon, and after exploring all the squares, has to return to its starting location. The robot is equipped with memory, but has no prior knowledge of the explored terrain. The view of the terrain is restricted to the four squares directly adjac...
متن کاملAn Improved WAGNER-WHITIN Algorithm
We present an improved implementation of the Wagner-Whitin algorithm for economic lot-sizing problems based on the planning-horizon theorem and the Economic- Part-Period concept. The proposed method of this paper reduces the burden of the computations significantly in two different cases. We first assume there is no backlogging and inventory holding and set-up costs are fixed. The second model ...
متن کاملAn Improved Algorithm for Network Reliability Evaluation
Binary Decision Diagram (BDD) is a data structure proved to be compact in representation and efficient in manipulation of Boolean formulas. Using Binary decision diagram in network reliability analysis has already been investigated by some researchers. In this paper we show how an exact algorithm for network reliability can be improved and implemented efficiently by using CUDD - Colorado Univer...
