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.

Abstract Although the net agricultural production across all regions of Africa has experienced a significant increase, African agriculture has performed below its potential over recent decades. Many aspects have been fronted to curb this situation, including sustainable intensification of farming systems and value-chain transformation through Conservation Agriculture (CA) across Africa. Based on the latest update, Africa has about 2.7 million ha under CA, an increase of 458% over the past 10 years with 2008/09 as baseline. However, this constitutes a mere 1.5% of the global area under CA, and less than 1.4% of the total cropland area in Africa. A combination of modern techniques and the optimization of agroecological processes in CA systems and practices requires that agricultural research plays a bigger role in its evolution and focus in the different regions of Africa. This targeted research should crucially contribute towards making agriculture in Africa more productive, competitive, sustainable and inclusive in terms of its functionality towards the farmer, society and nature. Scientific solutions for agricultural transformation need to be pursued without losing sight of the potentials and fragility of Africa's agricultural environments, the complexity of its agricultural production systems and the continent's rich biodiversity. The agricultural research and development agenda in Africa must build on the rich traditional farming culture, knowledge and practices, supported by coherent longer-vision for investments in science for agricultural development. Most of these investments are expected to come from national public and private sources, with governments also expected to invest in generation of 'public goods' such as the national or global environmental benefits typical of CA, and to also catalyse innovation and support market growth. The absolute imperative is that farmers must shift from outdated conventional tillage-based methods to modern, well-tested and knowledge-based methods of land use. Making this transition will be difficult without the creation of an enabling environment. This chapter discusses the various roles and advances required in CA-based research that will support the adoption of CA systems by millions of smallholder farmers in Africa with a view to enhancing sustainable and effective agricultural development and economic growth.

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.

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.
