Abstract A rationale is offered and methodology illustrated for integrating the fundamental steps involved in the collection and processing of blood for laboratory evaluation. The approach taken in the development of these concepts and components greatly extends the possibilities of laboratory systems integration without upsetting established modalities. A prototype design of the integrated blood-collection system integrates blood collection, cellular separations, sample transfer to stable storage without chemical mediators, and sample presentation for chemical analysis (e.g., precision metering) while preserving patient identification. A sophisticated, multi-chambered blood-collection container is the site of all blood sample processing and transfer steps. This device is supported by a compact, robotic centrifuge of unique design and a transfer mechanism to facilitate sample delivery for analysis within a diagnostic instrument. The confluence of these individual components into a single integrated system provides the means to completely automate the processing of blood samples, after sample collection, eliminating all manual transfer steps and any external exposure of blood interfaces outside the diagnostic instrument. Configurational derivatives of the Integrated Blood-Collection System offer choice of skin or venipuncture procedure, rapid plasma extraction for micro- or macro-collected volumes, and sample delivery by either aspiration or direct metering of discrete 10-microL samples from the collection container. The skin-puncture configuration provides the opportunity within a single device to collect and process up to 500 microL of sample by capillarity from a skin prick.

Harmful Microalgae

The multiplication of harmful microalgae in bivalve mollusc fishingregions is a problem that has repercussions for both fishermenand for the economy of the affected region, as these microalgaeproduce toxins that affect humans, ranging from gastrointestinalproblems to, in more extreme cases, cancer that can lead to thedeath of the consumer. Currently, in Santa Catarina, the water isanalyzed to identify the presence of toxins by the Integrated Companyof Agricultural Development of Santa Catarina (CIDASC). Thepresence of toxins in the water creates a temporary embargo onthe sale of mollusks. This embargo usually produces great loss inthe bivalve mollusc culture as far as all the production needs do bediscarded. This work creates a sample collection system that canbe performed by growers rather than experts for the acquisition ofthose samples. These work aims to create an easy-to-use systemenabling the mariculturist to sample water. The purposed processallows the acceleration of the sample collection and analysys. Themanual process needs an expert to come to the field, collect samples,document the samples and take to the lab to analyze. In thisstudy we created an embedded system for sample collection thatautomated the collect field data and link to a image collected bya portable microscope and when a wifi connection is detected itsends the sample to a data server.

Significant Difference

Abstract We examined the sensitive assay for carboxyhemoglobin based on reaction with K3Fe(CN)6 and gas chromatography of the liberated CO. Our improvements included increased baseline stability, shorter analysis time, and simpler standardization. EDTA-containing Vacutainer Tubes (lavender-stoppered) increase the carboxyhemoglobin content of blood stored in them. The carboxyhemoglobin content of blood stored in capillary tubes containing solid heparin and saponin remained stable for two weeks. Using our improved procedures, we measured the carboxyhemoglobin content of blood from adults and neonates collected via venipuncture or heel or fingersticks. We observed no significant difference in carboxyhemoglobin content of blood obtained by venipuncture or heel stick for premature infants, 0.19 +/- 0.04 vs 0.18 +/- 0.03 mL of CO per 100 mL of blood, respectively (mean +/- SD). Nonsmoking adults (n = 19) had CO values (mean +/- SD) of 0.19 +/- 0.03 and 0.17 +/- 0.04 mL per 100 mL of blood, and smoking adults (n = 7) gave CO values of 0.96 +/- 0.49 and 0.91 +/- 0.49 mL/dL, for venipuncture and fingerstick, respectively.

Axial Flow Cyclone

Abstract A new aircraft-based cloud water collection system has been developed to provide samples of cloud water for chemical analysis. The collection system makes use of centrifugal separation in an axial-flow cyclone to remove cloud drops from the airstream. An automated sample storage system allows up to seven independent samples to be obtained during a single research flight. The entire collection system is housed in a Particle Measurement Systems (PMS) canister to permit the collector to be used on a range of research aircraft without extensive modification to the collector or the aircraft structure. Computational fluid dynamics (CFD) analysis was used extensively throughout the development of the new collector for component design and to predict internal flow dynamics. CFD-based cloud drop trajectory simulations provided an estimate of collection efficiency as a function of drop size. Based on the numerical modeling, the 50% cut diameter was predicted to be 8 μm. Through a quantitative laboratory calibration using fluorescein-tagged monodisperse drops, CFD predictions of drop deposition patterns in the interior of the axial-flow cyclone were verified. The numerical and experimental evaluations were performed to ensure that the population of collected cloud drops is well characterized. Initial flight testing of the system occurred during the Dynamics and Chemistry of Marine Stratocumulus, Phase II (DYCOMS-II) field project in July 2001. Although the major components of the prototype collection system operated as expected during flight testing, sample collection rates were lower than expected because of the inefficient removal and storage of cloud water collected in the axial-flow cyclone. Actual sample collection rates ranged between 0.1 and 1.2 mL min−1.
