Implementation of six sigma methodology for the elimination of contamination in Fine Pitch connectors
Quality drives companies to evolve, providing what customers need or even exceeding their expectations through products and services that play their functions properly during their lifetime. From this perspective, this study aims to solve a concrete defect that occurs during the assembly process of an electronic product for the automotive industry. One of the new challenges in the electronics industry is the contamination issue in Printed Circuit Boards (PCB). Contamination can be defined as any type of particles (residues) that are deposited on PCB surface or within a component, causing unwanted behaviours in the electronic device. In the present study, the investigated contamination is organic in nature and is originated by the solder flux. The solder flux is released during the welding process, being deposited inside the PCB Fine Pitch connectors. The DMAIC method was adopted as a Problem Solving tool. This method was selected to ensure the elimination of this type of defect. To support the investigation, the 5W2H and Is/Is Not quality tools were used. The investigation was developed by a multidisciplinary team. After the root-cause identification, the connectors provider was involved to assist in the development of an effective and low cost solution. The final solution resulted in the placement in the connectors of a protective cap. This solution, besides protecting the connectors, allowed a new collaborative relationship along the supply chain

COVID-19 Management in Clinical Dental Care Part II: Personal Protective Equipment for the Dental Care Professional
Background: Facing the coronavirus disease 2019 (COVID-19) challenge on a global level, dental care professionals are encouraged to optimize universal precautions and adopt measures that ensure protection against infection by contaminated aerosols and droplets. Although aerosol transmission is possible, direct contact through large droplets is probably responsible for the vast majority of transmissions.
Methods: This paper is the second of a series of 3 on the management of COVID-19 in clinical dental care settings and aims to describe the selection and use of personal protection equipment (PPE) by dental care professionals (DCP), with consideration of the level of risk associated with the planned procedures. PPE selection depends directly on the local epidemiological setting, the patient's characteristics, and the level of risk of the planned procedures. The procedures performed in the office environment are classified as low-, moderate-, or high-risk. Moderate risk includes 2 further sublevels associated with the cleaning, disinfection, and sterilization of materials for clinical procedures that do not generate aerosols. The training of DCP on how to properly don (put on) and doff (remove) PPE is as important as choosing the appropriate PPE because it can be associated with a risk of infection.
Discussion: When there is limited availability of PPE, measures should be adjusted to the risk associated with the intervention. Assuming that an effective COVID-19 vaccine will be developed, once it becomes widely available for DCP, PPE requirements will likely be different.
Conclusion: The proper use of PPE, together with the adoption of other operational procedures, can provide effective protection against microorganisms being transmitted via body fluids or in the air.This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors

Resolving the Diplodia complex on apple and other Rosaceae hosts
Diplodia species are known as pathogens on many woody hosts, including fruit trees, worldwide. In this study a collection of Diplodia isolates obtained mostly from apple and other Rosaceae hosts were identified based on morphological characters and DNA sequence data from ITS and EF1-α loci. The results show that the diversity of species associated with twig and branch cankers and fruit rot of apples is larger than previously recognised. Four species were identified, namely D. seriata and D. malorum (which is here reinstated for isolates with D. mutila-like conidia). Diplodia intermedia sp. nov. is closely related to D. seriata, and D. bulgarica sp. nov. is morphologically and phylogenetically distinct from all Diplodia species reported from apples.publishe
