Communication in Diagnostic Radiology

Communication in the diagnostic radiology department in regard to the current work load has been discussed with certain recommendations being made to increase efficiency. The need for improvement in communication equipment and techniques is necessitated by problems facing diagnostic radiology today.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/73519/1/j.1440-1673.1972.tb01316.x.pd

Analysis of factors influencing the ultrasonic fetal weight estimation

Objective: The aim of our study was the evaluation of sonographic fetal weight estimation taking into consideration 9 of the most important factors of influence on the precision of the estimation. Methods: We analyzed 820 singleton pregnancies from 22 to 42 weeks of gestational age. We evaluated 9 different factors that potentially influence the precision of sonographic weight estimation ( time interval between estimation and delivery, experts vs. less experienced investigator, fetal gender, gestational age, fetal weight, maternal BMI, amniotic fluid index, presentation of the fetus, location of the placenta). Finally, we compared the results of the fetal weight estimation of the fetuses with poor scanning conditions to those presenting good scanning conditions. Results: Of the 9 evaluated factors that may influence accuracy of fetal weight estimation, only a short interval between sonographic weight estimation and delivery (0-7 vs. 8-14 days) had a statistically significant impact. Conclusion: Of all known factors of influence, only a time interval of more than 7 days between estimation and delivery had a negative impact on the estimation

Distributed robotic target acquisition using bluetooth communication

This paper presents a distributed multi-robot system designed to solve a team-based search and destroy task. The project was divided into two phases. The initial phase was used to demonstrate the use of Bluetooth communication for coordinated robotic search. The second (current) phase of the project attempts to integrate these early developments. This integration allows two seeker robots to locate and coordinate an attack on a target (enemy). The goal of the first phase was to develop a robot communication strategy using Bluetooth for the Honeybee task. The goal of the second phase was to take the communication strategy and use it in the team-based search and destroy task. A secondary goal in the current phase was to convert a model tank into a robust autonomous vehicle. We present the details of the phases, the progress made towards achieving the goals, and the directions we plan to take after the current phase is complete

Efficiency of the Summer Monsoon in Generating Streamflow Within a Snow‐Dominated Headwater Basin of the Colorado River

The North American Monsoon occurs July–September in the central Rocky Mountains bringing significant rainfall to Colorado River headwater basins. This rain may buffer streamflow deficiencies caused by reductions in snow accumulation. Using a data-modeling framework, we explore the importance of monsoon rain in streamflow generation over historical conditions in an alpine basin. Annually, monsoon rain contributes 18 ± 7% water inputs and generates 10 ± 6% streamflow. The bulk of rain supports evapotranspiration in lower subalpine forests. However, rains have the potential to produce appreciable streamflow at higher elevations where soil moisture storage, forest cover, and aridity are low and rebound late season streamflow 64 ± 13% from simulated reductions in spring snowpack as a function of monsoon strength. Interannual variability in monsoon efficiency to generate streamflow declines with low snowpack and high aridity, implying the ability of monsoons to replenish streamflow in a warmer future with less snow accumulation will diminish

Organic and conventional fertilization procedures on nitrate, antioxidants and pesticide content in parts of vegetables

Different parts of plant foods are generally discarded by consumers such as peel, stalk and leaves, which could although possess a nutritional value. However, few studies have analyzed the composition of these marginal foods. Phenolic compound, flavonoid, polyamine, nitrate and pesticide contents of parts of vegetables that are usually discarded, cultivated according to conventional and non-conventional procedures, were analyzed aiming to provide suggestions on how to improve the consumption of these parts and to reduce the production of urban solid wastes. Few, but significant, differences between the two manuring procedures were observed. Higher nitrate content and the presence of organochlorine pesticides were found in conventional cultivated papaya peel, lemon balm leaves, jack fruit pulp, beet stalk and peel. Discarded parts of plant foods such as stalk, leaves, and peels, can be used as a source of antioxidant compounds, such as phenolic compounds
