Coupling production networks and regional assets in manufacturing clusters

Paradoxically, the ongoing process of globalisation goes hand in hand with a surge of interest in the ‘local’ sources of firm competitiveness. In this paper, we develop a frame of analysis that helps to understand ‘coupling’ of production networks and regional development. Our aim is to reflect on the ‘spatiality’ of different types of networks, and to study the dynamic coupling process between these networks and regional assets. We apply the framework to two case studies – shipbuilding in Turku and machine building in Porto. Our analysis points towards the relevance of regional assets facilitating this coupling process and in strengthening regions as magnets for global production networks, reinforcing the long term sustainability of different types of clusters

Preliminary study on the potential use of RPA images to quantify the influence of the defoliation after coffee harvesting to its yield

Received: January 24th, 2023 ; Accepted: May 22nd, 2023 ; Published: September 18th, 2023 ; Correspondence: [email protected] is an agricultural commodity with global commercial importance capable of impacting the production chain. The quantification of defoliation at harvest is important for monitoring crop yield because defoliation is one of the main types of damage caused by this agricultural operation in coffee crops. Thus, the objective of this study was to evaluate the relationship between yield and defoliation obtained in the field and obtained through remotely piloted aircraft (RPA) images. The experiment was conducted in a coffee plantation belonging to the Federal University of Lavras (UFLA), Lavras, Minas Gerais state, Brazil. An RPA with a rotary wing containing a multispectral camera was used in autonomous flight mode with a height of 30 m, an image overlap of 80%, and a speed of 3 m s-1 . The images were collected before and after the 2020 and 2021 harvest, defoliation data obtained in the field were measured in 2020 and 2021, and the yield was measured from 2019 to 2021. Image processing was performed in the software PhotoScan, postimage processing was performed in QGIS, and statistical analyses were performed using the software R. With the processing of the images in 2020, the crop showed reductions of 17.3% and 18.4% in leaf area and volume, respectively, after harvest. In 2021, the crop showed reductions of 12.8% and 9.8% in leaf area and volume, respectively, after harvest. The leaf area and leaf volume of the coffee plantation after harvest could be quantified by means of images obtained by RPA, which allowed the observation of the loss of area and volume of the coffee plantation. Furthermore, it was possible to analyse the interactions between field data and the yield of the same harvest year, which were directly proportional, and the interaction of image data from one year with the previous yield, which were inversely proportional. In the year 2020, there was a reduction of 17.3% in leaf area after harvest, and a reduction of 18.4% in leaf volume after harvest in the plots under study.In the processing carried out in 2021, there was a 12.8% reduction in leaf area after harvest, and a 9.8% decrease in leaf volume after harvest in the plots under study

Knowledge Locations in Cities: Emergence and Development Dynamics

This thesis studies the development of knowledge locations: area-based initiatives aimed at agglomerating knowledge-intensive activities in a designated area or city district (e.g. technology parks, creative “factories”). It relates the reinvigorated interest (and qualitative change) in knowledge locations with a number of societal evolutions, and develops a theoretical framework to explain their emergence and development. This framework contributes to better ground the study of knowledge locations within the spatial-economic context and dynamics of its host cities and regions. This study also explores the relation between a knowledge location´s features – Specialization, Urban-spatial integration and Management – and their agglomeration outcomes. It shows that there are multiple pathways to growth and agglomeration: no single factor has to be always present to explain it at a certain moment in time. Moreover, the three factors proved relevant but in different ways, and namely to the extent that they contribute to image formation (associated with the identification of a concept) and ecosystem formation (associated with exchange and learning among tenants). Those processes provide two different paths to agglomeration. Their interaction influences the development of a knowledge location over time and, ultimately, the relation between the location and change in its spatial-economic context. The abovementioned phenomena are explored with the support of four European case studies of “themed” knowledge locations, focusing on audiovisual, biotechnology, design and digital media, respectively

Effectiveness of XP-endo finisher in the reduction of bacterial load in oval-shaped root canals

This study investigated the effectiveness of XP-Endo Finisher (XPF) associated with XP-Endo Shaper (XPS) or Reciproc Blue (RB) files in reducing bacterial load in oval-shaped root canals (RC) during chemomechanical preparation (CMP) using 0.9% saline solution (NaCl) or 2.5% sodium hypochlorite (NaOCl). Eighty mandibular incisors with single oval-shaped RC were contaminated with Enterococcus faecalis. The teeth were randomly assigned to eight experimental groups (n = 10) according to the CMP, as follows: G1: XPS, G2: XPS + XPF, G3: RB, and G4: RB + XPF. CMP was performed with NaCl or NaOCl. The reduction of bacterial load was assessed by colony-forming unit count before (S1) and after (S2) CMP. Data normality was verified by using Shapiro-Wilk test. ANOVA, Tukey's test, and Bonferroni post-hoc test were used at a 5% significance level. Culturable bacteria were present in all S1 samples (p>0.05). All instrumentation techniques were effective in reducing bacterial load, irrespective of the irrigating solution (p < 0.05). With the use of NaCl, RB was more effective than XPS (p = 0.035). With the use of NaOCl, XPS and RB presented similar effectiveness (p = 0.779). XPF enhanced the bacterial reduction of both systems tested (p < 0.05). The use of NaOCl improved the CMP, irrespective of the instrumentation technique used (p < 0.05). In conclusion, XPS and RB files are effective in reducing bacterial levels in oval-shaped RC. The use of XPF as a method of agitation of the irrigating solution improved the cleaning efficiency of both file systems tested. Mechanical preparation performed with saline solution decreased culturable bacteria from the root canal, but antimicrobial substances such as NaOCl should be used to achieve a significantly better disinfection33CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP308162/2014-5não tem2015/23479-

Performance of Orius insidiosus after storage, exposure to dispersal material, handling and shipment processes

Storage, handling and shipment procedures are important factors influencing the quality of biological control agents. This study aimed to evaluate biological parameters and performance of Orius insidiosus (Say) after different storage periods at low temperatures, after exposure to different dispersal materials in containers, and after handling the predator during the shipment and delivery processes. Storage periods were 2, 4, 6, 8, 10, 12, 14, 16, 18 and 20 days at temperatures of 5, 8, 10 and 12 ± 1 °C, RH 70 ± 10% and under continuous scotophase. A mix of 75% adults and 25% 5th instar nymphs of O. insidiosus was kept in plastic containers (200 mL) for a 72 h period, supplied with eggs of Anagasta kuehniella (Zeller) as food, farmer’s friend inflorescence (Bidens pilosa L.) as oviposition substrate and source of moisture, and one of the following dispersal materials: vermiculite + rice hulls (1:1), vermiculite, folded paper towels, sawdust, and coffee husk. Also, similar mixes of nymphs and adults were exposed to a 72 h shipment and delivery process. We found that O. insidiosus can be stored up to 10 days at 8 °C without loss of quality. Interestingly, storage of mated female predators results in a much higher fecundity post-storage than storage of virgin females. Vermiculite + rice hulls was by far the best dispersal material, and shipment of the predators by post during 72 h in Styrofoam boxes with plastic containers with vermiculite + rice hulls and A. kuehniella eggs did not negatively affect their survival and predation capacity. Our results can be used in planning mass-rearing and shipment, and to improve the quality of the predator O. insidiosus by using the right storage temperature, storage period and dispersal material

pH-Channeling in Cancer: How pH-Dependence of Cation Channels Shapes Cancer Pathophysiology.

Tissue acidosis plays a pivotal role in tumor progression: in particular, interstitial acidosis promotes tumor cell invasion, and is a major contributor to the dysregulation of tumor immunity and tumor stromal cells. The cell membrane and integral membrane proteins commonly act as important sensors and transducers of altered pH. Cell adhesion molecules and cation channels are prominent membrane proteins, the majority of which is regulated by protons. The pathophysiological consequences of proton-sensitive ion channel function in cancer, however, are scarcely considered in the literature. Thus, the main focus of this review is to highlight possible events in tumor progression and tumor immunity where the pH sensitivity of cation channels could be of great importance

Síndrome de Down hereditario poco común debido a la translocación robertsoniana 15/21: asesoramiento genético y reproductivo

Los portadores de un reordenamiento que afecta al cromosoma 21 tienen un riesgo potencial de concepciones genéticamente desequilibradas que pueden dar origen a niños con síndrome de Down (SD). Los riesgos reproductivos de las parejas portadoras de una translocación robertsoniana equilibrada dependen de los cromosomas reordenados y del sexo del portador. Este artículo tiene como objetivo analizar la tendencia de segregación y reproductiva de una rara translocación 15/21 en cinco generaciones de una familia. Se consideraron los avances actuales en tecnología reproductiva como una posibilidad para evitar la aneuploidía fetal. Dado el riesgo genético, el diagnóstico de preimplantación aparece también como una alternativa para evitar la posibilidad de un aborto posterior no deseado y para obtener una descendencia saludable
