Patrimonializzare il giardino d'inverno nella sua natura polimaterica. Progetto, trasformazioni d'uso e conservazione della serra sul lanificio Zegna a Trivero di Pietro Porcinai /The heritage of the winter garden in its polymaterial nature. Project, repurposing and conservation of Pietro Porcinai's greenhouse on the Zegna wool mill in Trivero
The paper emphasises the need to include winter gardens within the heritage-making processes, acknowledging their fragility due to the delicate balance between architecture and landscape, vegetation and minerals. Within this framework stands the winter garden designed by Pietro Porcinai for Aldo Zegna, between 1962 and 1964, on the roof of the wool mill in Trivero, recently included in the mapping of Censimento delle Architetture italiane dal 1945 ad oggi. The interventions relative to the repurposing of the complex into an archival and museum hub have modified its original spatial and compositional values, compromising the polymaterial nature of the work by privileging architecture over the garden. Ultimately, this case calls for reflection on the conservation of what re-mains authentic of the designer's intuition and authorship, despite the transformation of its intended use. Keywords Pietro Porcinai, Winter Garden, Heritage, Re-use, Conservation.

Genomic Characterization of Quality Wool Traits in Spanish Merino Sheep
The native Spanish Merino breed was the founder of all the other Merino and Merino-derived breeds worldwide. Despite the fact that this breed was created and improved to produce the highest quality fine wool, the global wool market crisis led to the wholescale crossing of most of the herds with breeds for meat purposes. Nevertheless, there are still some purebred animals with a high potential for producing quality wool. The objective of this study was to characterize the current wool quality of the breed and identify genes associated with these parameters. To achieve this, over 12,800 records from the most representative animals of the breed (registered in the herd book) were analyzed using the Australian OFDA 2000 system, for parameters such as fiber diameter (FD), standard deviation (SD), coefficient of variation (CV), fibers over 15 microns (>15%), staple length (SL), and comfort factor (CRV). Additionally, animals with the most extreme FD values were whole-genome sequenced using NGS. Genome-wide association studies (GWAS) determined the association of 74 variants with the different traits studied, which were located in 70 different genes. Of these genes, EDN2, COL18A1, and LRP1B, associated with fibers over 15%, and FGF12 and ADAM17, associated with SL, play a key role in hair follicle growth and development. Our study reveals the great potential for recovering this breed for fine wool production, and identifies five candidate genes whose understanding may aid in that selection process.

Physico-Mechanical Properties of Dupska Pramenka Wool as Breed Characterization Descriptors
The characterization of animal genetic resources includes morphometric, production and genetic characterization. This paper aims to determine the annual yield, staple length, and physico-mechanical properties of the wool of the Dupska Pramenka sheep. The average annual wool yields of a total of 130 ewes and 14 rams enrolled in the study were 2.120 kg and 3.340 kg, respectively. Wool samples were taken from the left shoulder, posterior rib, and pelvis of a total of 50 sheep (36 ewes and 14 rams). The lengths of wool staples collected from three body sites of the ewes were 20.92 cm, 21.75 cm, and 22.25 cm, respectively. The lengths of wool staples collected from three body sites of rams were 23.50 cm, 22.14 cm, and 23.64 cm, respectively. The height and length of wool fibers of the ewes were 21.97 cm and 22.85 cm on the shoulder, 22.38 cm and 23.10 cm on the posterior rib, and 23.06 cm and 23.77 cm on the pelvis. The height and length of wool fibers of the rams were 22.00 cm and 22.89 cm on the shoulder, 22.54 cm and 23.26 cm on the posterior rib, and 22.61 cm and 23.40 cm on the pelvis. The average fineness of wool fibers of the ewes was 43.08 µ, whereas the fineness of wool fibers of the rams was 45.43 µ. The Dupska Pramenka sheep were found to have mixed fibers: axillary (over 45µ), accounting for51.64% in the ewes and 54.91% in the rams, and transitional (30–45µ), accounting for 28.76% in the ewes and 32.80% in the rams. Fiber fluff (10–30µ) accounted for 19.83% and 12.98% in the fleeces of ewes and rams considered, respectively.

Screened of long non-coding RNA related to wool development and fineness in Gansu alpine fine-wool sheep
Wool growth and fineness regulation is influenced by some factors such as genetics and environment. At the same time, lncRNA participates in numerous biological processes in animal production. In this research, we conducted a thorough analysis and characterization of the microstructure of wool, along with long non-coding RNAs (lncRNAs), their target genes, associated pathways, and Gene Ontology terms pertinent to the wool fineness development. The investigation utilized scanning electron microscopy and transcriptomic technology, focusing on two distinct types in Gansu alpine fine-wool sheep: coarse type (group C, MFD = 22.26 ± 0.69 μm,
n
= 6) and fine type (group F, MFD = 16.91 ± 0.29 μm,
n
= 6), which exhibit differing wool fiber diameters. The results showed that fine type wool fiber scales were more regularly distributed in rings with large scale spacing and smooth edges, while coarse type wool fiber scales were more irregularly arranged in tiles with relatively rougher edges, and the density of wool scales was greater than that of fine type wool. Furthermore, a comprehensive analysis revealed 164 differentially expressed lncRNAs along with 146 potential target genes linked to these lncRNAs in the skin tissues from groups C and F. Utilizing functional enrichment analysis on the target genes, we successfully identified a number of target genes might be associated with the improvement of wool fineness, such as

, which are related to hair follicle development, histidine metabolism, epidermal cell differentiation, oxidative phosphorylation and hair cycle process. Additionally, the interoperability network involving lncRNAs-mRNAs indicated lncRNAs (MSTRG.17445.2, XR_006060725.1, MSTRG.871.1, MSTRG.10907.4) might play a significant role in the wool growth development and fineness improvement process. In conclusion, the research enlarges the current lncRNAs database, providing a new insight for the investigation of wool fineness development in fine-wool sheep.

The English wool market, c. 1230-1327
The wool market was extremely important to the English medieval economy and wool dominated the English export trade from the late thirteenth century to its decline in the late fifteenth century. Wool was at the forefront of the establishment of England as a European political and economic power and this volume is the first study of the medieval wool market in over 20 years. It investigates in detail the scale and scope of advance contracts for the sale of wool; the majority of these agreements were formed between English monasteries and Italian merchants, and the book focuses on the data contained within them. The pricing structures and market efficiency of the agreements are examined, employing practices from modern finance. A detailed case study of the impact of entering into such agreements on medieval English monasteries is also presented, using the example of Pipewell Abbey in Northamptonshire.
