Objective: To describe the systematization of the Nile tilapia cultivation process using a computer system for production and marketing traceability based on ISO 12877:2011 standard and web technologies. Design/methodology/approach: A documentary and field investigation were conducted to learn about the Nile tilapia production process currently applied; traceability was evaluated based on Double T and María del Carmen study cases, aquaculture farms located in the municipalities of Manzanillo and Armería located in the state of Colima, México; the process was contrasted with the ISO standard and the system was developed and implemented. Results: A Traceability System that records backward, internal, and forward procedural activities in the cultivation and marketing of tilapia. The system improves food safety control by registering lot care based on the ISO standard, resulting in well-defined traceable processes in the production and commercialization of the Nilotic tilapia. Limitations on study/implications: The results shown are related to the development and implementation of the system; however future work is yet to be carried out to assess its effect on the production and commercialization of farmed tilapia, as well as the efficiency of traceability. Findings/conclusions: The system was developed taking into consideration the necessary indicators for an ISO certification. Hence, aside from simplifying the registration and consultation of information, the producing company has the benefit of earning a certification for the aquaculture production process, creating additional value to its products.

Additional Value

We discuss how a short-range wireless communication service implemented for modern mobile communication devices can provide additional value for both the consumer and the service/product provider. When used as an information search tool, such systems allow services and products being promoted at the location they are available. For the customer, it may provide a “digitally augmented vision”, an enhanced view to the current environment. With data filtering and search rules, this may provide a self-manageable context, where the user's own personal environment and preferences to the features available in the current surroundings cooperate with a direct connection to the web-based social media. A preliminary design for such service is provided. The conclusion is that the method can generate additional revenue to the company and please the customers' buying process. In addition to the marketing, the principles described here are also applicable to other forms of human interaction.

Sampling Season

The gut microbiota of fishes is known to play an essential role in diverse aspects of host biology. The gut microbiota of fish is affected by various environmental parameters, including temperature changes, salinity and diet. Studies of effect of environment on gut microbiota enables to have a further understanding of what comprises a healthy microbiota under different environmental conditions. However, there is insufficient understanding regarding the effects of sampling season and catching site (wild and aquaculture) on the gut microbiota of Nile tilapia. This study characterised gut microbial composition and diversity from samples collected from Lake Tana and the Bahir Dar aquaculture facility centre using 16S rDNA Illumina MiSeq platform sequencing. Firmicutes and Fusobacteria were the most dominant phyla in the Lake Tana samples, while Proteobacteria was the most dominant in the aquaculture samples. The results of differential abundance testing clearly indicated significant differences for Firmicutes, Fusobacteria, Bacteroidetes and Cyanobacteria across sampling months. However, Proteobacteria, Chloroflexi, Fusobacteria and Cyanobacteria were significantly enriched in the comparison of samples from the Lake Tana and aquaculture centre. Significant differences were observed in microbial diversity across sampling months and between wild and captive Nile tilapia. The alpha diversity clearly showed that samples from the aquaculture centre (captive) had a higher diversity than the wild Nile tilapia samples from Lake Tana. The core gut microbiota of all samples of Nile tilapia used in our study comprised Firmicutes, Proteobacteria and Fusobacteria. This study clearly showed the impact of sampling season and catching site (wild and aquaculture) on the diversity and composition of bacterial communities associated with the gut of Nile tilapia. Overall, this is the first study on the effects of sampling season and catching site on the gut microbiota of Nile tilapia in Ethiopia. Future work is recommended to precisely explain the causes of these changes using large representative samples of Nile tilapia from different lakes and aquaculture farms.

<div class="WordSection1"><p><span style="font-size: 10px;">With the recent achievements in Internet and communication technology and its utilization in online laboratory, remote learning and online laboratory are made possible in the last few decades. This not only provides learning opportunities for people living in rural areas of developing countries, but also offers simple alternatives for those who are already able to access educational resources. The evolution of Web technologies makes it relatively easy to facilitate laboratory deployments, thus, more and more different online laboratory platforms emerge. However, the use of Hyper Text Mark-up Language (HTML5) and related standards such as WebGL and CSS3 in experimental platform, which is future trends and provides full-featured environment, is rare so far. This paper introduces a new HTML5 version of Networked Control System Laboratory (NCSLab), which has been developing for over 10 years since 2006. The 3D version of NCSLab has been developing for almost 5 years in Wuhan University (WHU), whose rendering solution is changed from Flash 3D engine to HTML5 recently. Therefore, Flash player plug-in is eliminated to provide better user experience for users since most of the mainstream web browsers are compatible with HTML5.</span></p></div>

The procedure of traceability of finished product, the regulating actions for tracking of products, beginning from the raw materials used for production of the single-part randomly chosen consumer package of a product and ending with shipment of this product to distributing facilities and also for tracking of processing of randomly chosen raw materials are offered. The traceability system does not guarantee a complete elimination of risk from arrival to the enterprise of improper raw and other materials, but allows tracking and identifying a source of nonconformance, after receiving of problem in quality of finished product. If a source of nonconformance is raw or other materials, then the manufacturer can allocate responsibilities for damage to property to the supplier of these raw or other materials. The procedure of traceability provides carrying out of training exercises at least once a year for determination of efficiency and working capacity of the current system of traceability, and also for identification and elimination of bottlenecks. For monitor and control over the stages of a process flow on the basis of the available database were proved the critical parameters of production process of confectionery, which control will allow to receive a safe product with the set technological and end-user performances. For monitor and control over the stages of a process flow on the basis of the available database on product traceability were proved the critical parameters of production process of confectionery, which control will allow to receive a safe product with the set technological and end-user performances. The accepted system eliminates a possibility of sales of products of nonconforming quality and allows to go back from the established control procedures that promotes the productivity enhancement.

Local Lotto is a 14-session curriculum designed for high school students to learn mathematics through an examination of the local lottery. The curriculum is organized around investigations of how local lottery games are won, who plays, how many people play, and where lottery revenues and prizes are distributed. A web-based application is integrated into the curriculum to allow students to explore the lottery in their school neighborhood, examine local lottery data, and assemble and justify their own arguments about the lottery. In this chapter, the authors describe technology's role in shaping a rich curriculum that engages students in investigating a local phenomenon while also addressing the content and practices of the Common Core State Standards of Mathematics. The chapter concludes with an outline of the challenges of integrating custom technologies into mathematics curricula and provides recommendations for future work.
