A Simple Photogrammetry Rig for the Reliable Creation of 3D Artifact Models in the Field: Lithic Examples from the Early Upper Paleolithic Sequence of Les Cottés (France)
There are three ways to view the 3D models in this data set. All models are freely available for download in the form of 3D PDFs. These can be opened in Adobe Reader or Adobe Acrobat. We are also making OBJ versions of these models available upon request the for educational and research purposes. Some models may also be viewed online within a web browser by visiting the first author's profile on the website Sketchfab. The URL for these models is https://sketchfab.com/port0228/folders. Because Sketchfab is a third-party site, the authors cannot ensure the longevity of these version of the models.
Two versions of a photogrammetric scale, which may be used during image capture to facilitate image alignment and model scaling, are also available here. If you encounter issues with photogrammetry software improperly aligning photos or not recognizing the coded targets included in version 1, we suggest trying our alternative scale, which uses non-coded markers and different reference patterns.
Specific questions about the site of Les Cottés and about access to additional materials may be addressed to Marie Soressi ([email protected]).3D scanning is becoming an increasingly utilized tool in archaeology. In comparison with other methods of 3D registration close-range photogrammetry has the benefits of being relatively inexpensive, mobile, and extremely adaptable for use in field conditions. Here, 3D models of lithic cores from the Châtelperronian, Protoaurignacian, and Early Aurignacian levels of the site of Les Cottés (France) are presented as examples of the quality of model that can be produced using photographs taken with a simple and inexpensive photogrammetry rig.Porter, Samantha T; Roussel, Morgan; Soressi, Marie.

Three Dimensional Models and Two Dimensional Cross Sections of Châtelperronian and Protoaurignacian Lithic Cores from the Sites of Les Cottés and Roc de Combe
These data were generated as part of a study investigating the use of quantitative methods on three dimensional models of lithic artifacts. The majority of the data set is comprised of 3D scans of Châtelperronian and Protoaurignacian cores from the site of Les Cottés (France), which were generated using photogrammetry. Although cores from the site of Roc de Combe were also scanned for the associated study, we are not able to make them available here due to rights restrictions. The second part of the data set includes two dimensional representations of cross sections, which were from the 3D artifact models. These were used in two analyses, which are described in the associated publication in JCAA (see citation below).Leakey FoundationService Régional de l’Archéologie (France)Department of Human Evolution of the Max Planck Institute for Evolutionary AnthropologyFyssen FoundationPorter, Samantha T; Roussel, Morgan; Soressi, Marie.

La buona gestione dell'impresa cooperativa
Questo libro presenta i risultati di una ricerca finanziata dal Dipartimento di Comunicazione ed Economia dell'Università di Modena e Reggio Emilia e patrocinata dall'ISVI (Istituto per i Valori d'Impresa) sul tema "imprenditorialità, buona governance e buon management nelle imprese cooperative". Dall'analisi di cinque casi di cooperative reggiane, scelte in quanto capaci di conseguire buoni risultati (a beneficio dei soci, del territorio e del proprio sviluppo, in condizioni di equilibrio economico-finanziario sostenibile) su archi di tempo non brevi, emerge innanzi tutto che la forma cooperativa è uno strumento potenzialmente utile a favorire il conseguimento di finalità diverse: di sviluppo dell'impresa e di consolidamento del settore; di perseguimento di una missione sociale; di rilancio di imprese in crisi grazie allo strumento del Worker Buy-Out. La seconda evidenza è che i risultati di un'impresa cooperativa dipendono dal funzionamento integrato di tre circuiti fra loro interconnessi che collegano la cooperativa stessa, rispettivamente, alla rete dei suoi soci, alle altre reti (formali e informali, locali e nazionali) del sistema cooperativo e agli stakeholder di tipo non cooperativo, rendendola attrattiva e, nel contempo, arricchendone la dotazione di valori, risorse e capacità. Tale funzionamento dipende a sua volta dalla qualità della governance, del disegno imprenditoriale e strategico, dei sistemi di gestione del personale e di altri processi manageriali-chiave, oltre che dal presidio costante dell'equilibrio economico-finanziario
Comportamiento de cuatro cultivares de Cucurbita maxima cv. zapallito frente al parasitismo del nematodo de las agallas Meloidogyne incognita
El nematodo de las agallas, Meloidogyne incognita, es causante de pérdidas productivas en los principales cultivos hortícolas que se realizan en el albardón costero santafesino. El objetivo de la investigación fue determinar la reacción de cuatro cultivares comerciales de zapallito redondo de tronco (Cucurbita maxima cv. zapallito) frente al parasitismo de M. incognita. Las experiencias se condujeron en macetas bajo invernadero y se evaluaron los cultivares Nacional, Premier, Sais superselección y Máximo. Los tratamientos consistieron en inocular plantas de cada cultivar con 100 juveniles de segundo estadio de M. incognita y de sus correspondientes testigos no inoculados. A los 45 días de la inoculación se determinó el número de agallas, Índice de Agallas, número de masas de huevos, Índice de Masas de Huevos, número de huevos y el factor e reproducción. Los cuatro cultivares estudiados demostraron ser susceptibles a M. incognita.The root-knot nematode, Meloidogyne incognita, causes yield losses in many horticultural crops in the coastal área of Santa Fe province. The aim of this research was to determine the reaction of four commercial cultivars of summer squash (Cucurbita maxima cv. zapallito) when parasitized by M. incognita. The experiments were conducted in pots under greenhouse conditions and Nacional, Premier, Sais superselection and Máximo cultivars were evaluated. The treatments consisted of plants of each cultivar inoculated with 100 second-stage juveniles of M. incognita and its corresponding control. 45 days after inoculation the number of galls, Gall Index, number of egg masses, Eggs Mass Index, number of eggs and reproduction factor were determined. The four cultivars studied showed susceptibility to M. incognitaFil: Guzmán, Alejandro. Universidad Nacional del Litoral. Facultad de Ciencias Agrarias; ArgentinaFil: del Valle, Eleodoro Eduardo.

Design Variations 2024 - Design is Happiness
"Design is Happiness" presenta i lavori degli studenti del laboratorio di Landscape and Interior Spatial Design condotto dai docenti Michele De Lucchi, Francesca Balena Arista, Marco De Santi e Francesco Clerici della Scuola del Design del Politecnico di Milano.
Gli studenti hanno progettato e realizzato dei modelli sospesi e dei brevi video che restituiscono le loro riflessioni sul tema della Felicità.
"Il nostro lavoro come designer, come architetti, come creativi in generale è trasformare degli argomenti intangibili in oggetti e spazi tangibili -spiega Michele De Lucchi- e questo passaggio dall’intangibilità alla tangibilità è veramente il processo di progettazione più puro, più importante che noi facciamo. Abbiamo dato agli studenti come tema di progetto non una tipologia di edificio o di spazio interno ma un tema astratto, una parola chiave sulla quale costruire un immaginario, costruire uno spazio visibile, che sapesse trasmettere e comunicare un valore intangibile. Il tema della felicità è sicuramente legato al tema della sostenibilità, alla necessità di trovare delle soluzioni per tutto quello che ci spaventa, per tutto quello che ci fa paura...e pensare a un futuro il più possibile felice, tranquillo, sereno."
La mostra si inserisce nell'ambito della tematica generale "Interdipendence", proposta quest'anno dalla Scuola del Design del Politecnico di Milano, aderendo al sottotema "Cultural and information interdipendence"."Design is Happiness" showcases the works of students from the Landscape and Interior Spatial Design workshop led by professors Michele De Lucchi, Francesca Balena Arista, Marco De Santi, and Francesco Clerici of the School of Design at Politecnico di Milano. The students have designed and created suspended models and short videos reflecting their thoughts on the theme of Happiness.
"Our work as designers, as architects, as creatives in general, is to transform intangible subjects into tangible objects and spaces," explains Michele De Lucchi, "and this transition from intangibility to tangibility is truly the purest, most important design process that we undertake. We have given the students a project theme not of a building typology or internal space, but an abstract theme, a keyword upon which to build an imaginary, to construct a visible space that knows how to convey and communicate an intangible value. The theme of happiness is certainly linked to the theme of sustainability, to the need to find solutions for everything that scares us, for everything that frightens us... and to think about a future that is as happy, calm, and serene as possible."
The exhibition fits within the general theme of "Interdependence" proposed this year by the School of Design at Politecnico di Milano, adhering to the sub-theme "Cultural and information interdependence.
