Validation study for the addition of Cicer arietinum (Desi type) as a species to which the conductivity test for seed vigour can be applied to support Rules proposal C.15.1

The conductivity test identified differences in field emergence of 11 seed lots of the Desi type of chickpea (Cicer arietinum). Six of these seed lots, all having a laboratory germination of more than 85%, were tested by four laboratories using the electrical conductivity test, as described in the ISTA Rules (ISTA 2015). All laboratories consistently identified the same significant differences in the seed lot conductivity and the results were repeatable within laboratories and reproducible between laboratories. This provides evidence in support of the addition of Cicer arietinum (Desi type), to the ISTA Rules as a species for which the conductivity test can be applied.EEA OliverosFil: Khajeh-Hosseini, Mohammad.

Genetic characterization of Theileria equi infecting horses in North America: evidence for a limited source of U.S. introductions

Background: Theileria equi is a tick-borne apicomplexan hemoparasite that causes equine piroplasmosis. This parasite has a worldwide distribution but the United States was considered to be free of this disease until recently. Methods: We used samples from 37 horses to determine genetic relationships among North American T. equi using the 18S rRNA gene and microsatellites. We developed a DNA fingerprinting panel of 18 microsatellite markers using the first complete genome sequence of T. equi. Results: A maximum parsimony analysis of 18S rRNA sequences grouped the samples into two major clades. The first clade (n= 36) revealed a high degree of nucleotide similarity in U.S. T. equi, with just 0–2 single nucleotide polymorphisms (SNPs) among samples. The remaining sample fell into a second clade that was genetically divergent (48 SNPs) from the other U.S. samples. This sample was collected at the Texas border, but may have originated in Mexico. We genotyped T. equi from the U.S. using microsatellite markers and found a moderate amount of genetic diversity (2–8 alleles per locus). The field samples were mostly from a 2009 Texas outbreak (n= 22) although samples from five other states were also included in this study. Using Weir and Cockerham’s FST estimator (θ) we found strong population differentiation of the Texas and Georgia subpopulations (θ= 0.414), which was supported by a neighbor-joining tree created with predominant single haplotypes. Single-clone infections were found in 27 of the 37 samples (73%), allowing us to identify 15 unique genotypes. Conclusions: The placement of most T. equi into one monophyletic clade by 18S is suggestive of a limited source of introduction into the U.S. When applied to a broader cross section of worldwide samples, these molecular tools should improve source tracking of T. equi outbreaks and may help prevent the spread of this tick-borne parasite

Cement matrix containing lightweight aggregate based on Non-Metallic Fraction Printed Circuit Boards (NMFPCB'S)

Materials such as river sand, used in construction, have a high demand, and thus generate great environmental impacts while being extracted, such as erosion of the rivers banks and your siltation. With the increasing restriction of river sand extraction which can generate a reduction in the product's offer in the civil construction sector, it is necessary to develop waste recycling technologies for the production of sands with less environmental impact. One of the alternatives for the production of mortar for construction is the replacement of sands extracted from rivers by waste from other industries, such as the electronics industry that presents large and growing production worldwide, due to technological advances. Thus, this work aims to evaluate the influence of partial replacement of quartz sand by lightweight aggregate based non-metallic fraction of printed circuit boards (NMFPCB's) on the properties of cementitious matrix in the fresh and hardened states. For this, the electronic components of the printed circuit boards (PCBs) were removed, they were grinded and then through magnetic and electrostatic separation processes to separate the most valuable and abundant part of metals. The water to cement ratio was 0.48 in all the experiments, the Portland cement to sand ratio was 1:3 (in mass) for the control, and the mortars with NMFPCB's replacement of sand by volume of 25% and 50% were also made. These were characterized mechanically by axial compressive strength test at different ages. The partial results showed that with the increase of sand substitution by NMFPCB's there was a reduction of the mortar consistency index in the fresh state. Results showed that matrix that suffered the substitution of sand by light aggregate, decreased the compressive strength in relation to the reference, but have potential to use in construction industry as blocks or non-structural elements

Building a user-oriented notification system at CERN

CERN, as many large organizations, heavily relies on a variety of communication means for different use-cases and teams. The large amount of notifications received every day leads to adverse consequences. For the users receiving them, it is challenging to control and keep track of where, how and when some information was received. At the same time for those sending and maintaining the tools that deliver notifications, it is difficult to choose which targets to adopt (email, messaging system and platforms, electronic devices, etc.). The CERN Notifications system aims at consolidating communication by providing a central place where notifications are created, maintained and distributed. CERN Notifications allows not only optimising the flow for the multiple people and teams which are responsible for sending, but also empowers the target users by respecting their preferences: how, where and when they receive their notifications. This paper describes the design and architecture of the CERN Notifications system and its components, how it was designed with a flexible and highly modular architecture which allows adding further device targets with little effort. Furthermore, it presents implementation details and the decisions behind those. And last but not least it describes the features that empower users to choose how to consume information sent to them

Large scale dynamic web deployment for CERN, experience and outlook

CERN hosts more than 1200 websites essential for the mission of the Organization, both for internal and external collaboration and communication, as well as public outreach. The complexity and scale of CERN’s online presence is very diverse with some websites, like home.cern, accommodating more than one million unique visitors in a day. However, regardless of their diversity, all websites are created using the Drupal content management system (CMS), and are self-hosted directly in the CERN Data Center on a dedicated infrastructure that runs on Kubernetes. Workflows like provisioning, deleting, cloning, upgrading, and similar are fully automated and managed by a customized Kubernetes controller. By leveraging the custom controller, the infrastructure has proven highly reliant with minimal, manual intervention necessary. In order to further automate deployments and improve governance, a customized version of Drupal called the CERN Drupal Distribution is implemented. Supported by end-to-end integration tests and automated browser simulation, this setup enables the propagation of security and feature updates seamlessly to all websites without any downtime. This paper outlines the architecture which allows building, testing, and distributing updates to a large number of websites without any downtime. Furthermore, it presents experiences and learnings from managing such a service at CERN with limited resources
