A Comprehensive Review of the Coffee Leaf Miner Leucoptera Coffeella (Lepidoptera: Lyonetiidae), With Special Regard to Neotropical Impacts, Pest Management and Control

The coffee leaf miner (CLM) Leucoptera coffeella moth is a major threat to coffee production. Insect damage is related to the feeding behavior of the larvae on the leaf. During the immature life stages, the insect feeds in the mesophyll, triggering necrosis and causing loss of photosynthetic capacity, defoliation, and significant yield loss to coffee crops. Chemical control is mandatory to sustain the coffee production chain, though market requirements move towards conscious consumption, claiming for more sustainable methods. In this overview, we discuss aspects about the CLM concerning biology, history, geographical distribution, economic impacts, and the most relevant control strategies in progress. Insights to develop an integrate approach for a safer and eco-friendly control of the CLM are discussed, including bio-extracts, nanotechnology, pheromones, and tolerant cultivars.

Sub-triangle opacity masks for faster ray tracing of transparent objects

We propose an easy and simple-to-integrate approach to accelerate ray tracing of alpha-tested transparent geometry with a focus on Microsoft® DirectX® or Vulkan® ray tracing extensions. Pre-computed bit masks are used to quickly determine fully transparent and fully opaque regions of triangles thereby skipping the more expensive alpha-test operation. These bit masks allow us to skip up to 86% of all transparency tests, yielding up to 40% speed up in a proof-of-concept DirectX® software only implementation.

Evaluation of Bioaerosol Bacterial Components of a Wastewater Treatment Plant Through an Integrate Approach and In Vivo Assessment

Wastewater carries different pathogenic and non-pathogenic microorganisms that can be dispersed in the surrounding environment. Workers who frequent sewage treatment plants can therefore be exposed to aerosols that contain a high concentration of potentially dangerous biological agents, or they can come into direct contact with contaminated material. This can lead to allergies, infections and occupational health-associated diseases. A characterization of biological risk assessment of bioaerosol exposure is necessary. The aim of this study was to evaluate the application of an interdisciplinary method that combines chemical and biological approaches for the analysis of a bioaerosol derived from a wastewater treatment plant (WWTP) situated in Italy. Sampled filters were analyzed by HPLC-MS/MS spectroscopy that searched for different chemical biomarkers of airborne microorganisms. The analytical quantification was compared to the biological cultural method that revealed an underrated microbial concentration. Furthermore, next generation sequencing analysis was used also to identify the uncultivable species that were not detected by the culture dependent-method. Moreover, the simple animal model Caenorhabditis elegans was used to evaluate the pathogenicity of two isolates—Acinetobacter iwoffii and Micrococcus luteus—that showed multidrug-resistance. This work represents a starting point for the development of a multidisciplinary approach for the validation of bioaerosol exposure on WWTP workplaces.

Workshop: Capacity building in public health in Northern Africa. A common effort to develop training programmes

Background In the years that have followed the overthrow of the former autocratic regime and the democratization of the country, the CONFIDE partner country, Tunisia, has experienced positive political and economic changes. These changes have driven important reforms in the field of public health, yet this country is facing important challenges in building a modern health system and finding an integrate approach to the main national public health problems. In terms of health research system, in Tunisia there is little coordination between stakeholders and the institutions in charge of public health. Moreover, there is no specific mechanism for informing the Ministry of Health about the progress of research in Tunisia and overall there is no structure responsible for the dissemination of research results to the public. To this end, the European and Tunisian members of this consortium have designed together the present capacity building project which aims to inform public health policies in Tunisia based on evidence and contribute to the development of public health research. The CONFIDE project is contributing to the development of the public health field in Tunisia and provides knowhow and tools to the Tunisian public health professions to better collaborate with the local stakeholders. Aim of the workshop The aim of this workshop is to share the experience of the capacity building process in the public health field in Northern Africa. The workshop will discuss and analyse the structure of opportunities for change and reform and the local needs of the public health domain in Tunisia and will identify the main challenges. We will present the processes used and challenges faced, but also the ways to overcome these challenges. This workshop will contribute to the European Public Health field by increasing the visibility at European level of the efforts directed to capacity building interventions and at transferring knowhow outside Europe, specifically Northern Africa. Program The introduction to the workshop will be made by Prof. Razvan Chereches MD, PhD, Professor of Public Health and coordinator of the CONFIDE project. He will describe the methodology used for the capacity building in public health trainings programme in Tunisia. The development of the Centre for Evidence Based Public Health in Tunisia and their impact on the Tunisian local and regional levels will be presented by Prof. Fatma Cheikhrouhou. The link between the knowledge transferred to the young professionals and the policy decision makers will be described by the Tunisian coordinator of the dissemination activities, Prof. Kalthoum Kallel. MScPH Maria Palianopoulou will follow with presenting the evaluation results of the capacity building process and lessons learnt. Last but not least, the sustainability of the trainings and the local effort to integrate the knowledge into the Medical University curricula will be presented by Assistant Prof. Mohamed ben Rejeb. Key messages Discussing lessons learnt can contribute to better tools for the development of public health. Partners` perspective and culturally adapted tools are important for high quality learning process.

A Dualistic Model of Tourism Seasonality: Approach–Avoidance and Regulatory Focus Theories

Seasonality in tourism is a key but poorly understood issue in the context of the tourism industry. Furthermore, theoretical and conceptual developments regarding seasonality in tourism remain limited. This conceptual study aims to integrate approach–avoidance and regulatory focus theories as frameworks for understanding seasonality in tourism. The study’s purpose is threefold. First, it evaluates current research on seasonality in tourism. Second, it outlines the features of approach–avoidance and regulatory focus theories and their underutilization in the tourism setting. Third, it illustrates the potential of the above theories and frameworks in understanding seasonality in tourism. Also important is our development of a dualistic model to augment policymakers’ understanding of how certain factors, such as fruition-based factors, structural factors, unforeseen factors, and climate-based factors, can influence seasonality in tourism. Implications and suggestions for future research are also discussed.

3D GEOMATICS TECHNIQUES FOR AN INTEGRATED APPROACH TO CULTURAL HERITAGE KNOWLEDGE: THE CASE OF SAN MICHELE IN ACERBOLI’S CHURCH IN SANTARCANGELO DI ROMAGNA

The modern Geomatics techniques, such as Terrestrial Laser Scanner (TLS) and multi-view Structure from Motion (SfM), are gaining more and more interest in the Cultural Heritage field. All the data acquired with these technologies could be stored and managed together with other information in a Historical Building Information Model (HBIM). <br><br> In this paper, it will be shown the case study of the San Michele in Acerboli’s church, located in Santarcangelo di Romagna, Italy. This church, dated about the 6th century A.D., represents a high relevant Romanic building of the high Medieval period. The building presents an irregular square plan with a different length of the lateral brick walls and a consequential oblique one in correspondence of the apse. Nevertheless, the different lengths of the lateral brick walls are balanced thanks to the irregular spaces between the windows. Different changes occurred during the centuries, such as the closing of the seven main doors and the building of the bell tower, in the 11th century A.D., which is nowadays the main entrance of the church. <br><br> An integrated survey was realized, covering the exterior and the interior. The final 3D model represents a valid support not only for documentation, but also to maintain and manage in an integrate approach the available knowledge of this Cultural Heritage site, developing a HBIM system in which all the mentioned historical, geometrical, material matters are collected.
