Young creators, designers, and master artisans are reinventing craftsmanship with their freshness and daring and turning it into a laboratory for sensory, emotional, and symbolic experiences. This paper will present artisans’ organizational status in the development of such a profession or craft in the municipalities that are part of the northern region of Valle del Cauca (Colombia). For this purpose, we resorted to documentary analysis and inquiries with stakeholders to characterize the region socially and demographically, for its geographical location, and identifying comparative and competitive advantages in the territory, according to the productive vocation of the municipalities and their relationship with crafts production. Likewise, the research analyzes artisans’ capabilities as a dynamizing sector for social, economic, and organizational processes. This study is a preliminary approach because its results are inconclusive, thus allowing other researchers to develop into the importance of the artisanal sector for the socio-economic development of the northern region of Valle del Cauca. The strategic approaches outlined in this paper are those consolidated with the stakeholders, who have enabled the craft sector’s strengthening through innovative proposals regarding the management of their workshops and business units.

Genomic Characterization

In many dairy products, Leuconostoc spp. is a natural part of non-starter lactic acid bacteria (NSLAB) accounting for flavor development. However, data on the genomic diversity of Leuconostoc spp. isolates obtained from cheese are still scarce. The focus of this study was the genomic characterization of Leuconostoc spp. obtained from different traditional Montenegrin brine cheeses with the aim to explore their diversity and provide genetic information as a basis for the selection of strains for future cheese production. In 2019, sixteen Leuconostoc spp. isolates were obtained from white brine cheeses from nine different producers located in three municipalities in the northern region of Montenegro. All isolates were identified as Ln. mesenteroides. Classical multilocus sequence tying (MLST) and core genome (cg) MLST revealed a high diversity of the Montenegrin Ln. mesenteroides cheese isolates. All isolates carried genes of the bacteriocin biosynthetic gene clusters, eight out of 16 strains carried the citCDEFG operon, 14 carried butA, and all 16 isolates carried alsS and ilv, genes involved in forming important aromas and flavor compounds. Safety evaluation indicated that isolates carried no pathogenic factors and no virulence factors. In conclusion, Ln. mesenteroides isolates from Montenegrin traditional cheeses displayed a high genetic diversity and were unrelated to strains deposited in GenBank.

In this research, the types of hemicellulose that predominate in the leaves and tops of the three most cultivated varieties (CC 8475, CC 8592, V 7151) of sugarcane (Saccharum officinarum L.) in Valle del Cauca, Colombia were determined. Hemicellulose analyses were performed after delignification with sodium chlorite and extraction with 18% NaOH and 24% KOH containing 0.26 M NaBH4. The main components of hemicellulose were identified via FTIR and NMR spectroscopy, and monomeric sugars were identified via HPLC. Hemicellulose A composed of arabinoxylans, glucomannans and arabinogalactactans and hemicellulose B primarily composed of arabinoxylans were extracted. The hemicelluloses of the Colombian varieties were more stable against heat than those of the Venezuelan variety. The results of this project allowed discovery of the potential use of agricultural sugarcane residues for bioethanol production because they have a holocellulose content of more than 60%.

ABSTRACTThis study presents a complete characterization of kenoplumbomicrolite, (Pb,□)2Ta2O6[□,(OH),O], occurring in an amazonite pegmatite from Ploskaya Mountain, Western Keivy Massif, Kola Peninsula, Murmanskaja Oblast, Northern Region, Russia.Kenoplumbomicrolite occurs in yellowish brown octahedral, cuboctahedral and massive crystals, up to 20 cm, has a white streak, a greasy lustre and is translucent. The Mohs hardness is ~6. Attempts to measure density (7.310–7.832 g/cm3) were affected by the ubiquitous presence of uraninite inclusions. Reflectance values were measured in air and immersed in oil. Kenoplumbocrolite is optically isotropic. The empirical formula is (Pb1.30□0.30Ca0.29Na0.08U0.03)Σ2.00(Ta0.82Nb0.62Si0.23Sn4+0.15Ti0.07Fe3+0.10Al0.01)Σ2.00O6[□0.52(OH)0.25O0.23]Σ1.00 (from the crystal used for the structural study) and (Pb1.33□0.66Mn0.01)Σ2.00(Ta0.87Nb0.72Sn4+0.18Fe3+0.11W0.08Ti0.04)Σ2.00O6[□0.80(OH)0.10O0.10]Σ1.00 (average including additional fragments). The mineral is cubic, space group Fd$\overline 3 $m. The unit-cell parameters refined from powder X-ray diffraction data are a = 10.575(2) Å and V = 1182.6(8) Å3, which are in accord with those obtained previously from a single crystal of a = 10.571(1) Å, V = 1181.3(2) Å3 and Z = 8. The mineral description and its name have been approved by the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association (IMA2015-007a).

At El Chucho creek, located to the west of the Valle del Cauca department in Colombia, some hydrothermal alterations affecting the Buga Batholith rocks and dykes of porphyritic quartz-dioritic and tonalitic composition were identified. These lithological units host mineral occurrences of pyrite, chalcopyrite, and molybdenite that occur disseminated in the rocks or associated with quartz veinlets. The hydrothermal alterations identified were phyllic, propylitic, and, in minor quantity, potassic. The two firsts alterations’ distribution is related to structures and pervasive, whereas the last one seems restricted to contact zones of porphyritic dykes on tonalite. Microthermometric data were acquired i) on quartz veinlets of 1 cm thick over a phyllic alteration zone, and ii) on quartz veinlet of 1 cm thick with chalcopyrite ± molybdenite and copper silicates, both veinlets cutting the phaneritic tonalite. Those data suggest that the mineralizing fluids have an aqueous-saline chemical system and were trapped under low volatile content. The microthermal data allowed authors to identify two mineralizing events. One of them of higher temperature, with homogenization temperatures between 275°C-480°C; as the second event is characterized by lower homogenization temperatures that range from 100°C to 139°C.

The Subject

Recently, some authors have pointed out that the subject of university–firm collaboration (UFC) in the teaching context has been neglected. To fill this gap, and considering that educational provision is co-created with various stakeholders, this study aims to provide an exploratory characterization of the current state of UFC in the teaching context and to explore UFC as a mechanism for the co-creation of value. A qualitative approach was chosen, through a case study applied to one faculty at a Portuguese university. Data were obtained through documentary analysis and interviews with people in charge of this faculty. The results suggest that collaboration activities in this domain occur, albeit not systematically or in a planned way. The involvement of the current faculty direction in stimulating this collaboration is recognized, and the leaders see this phenomenon as a mechanism for co-creating value between firms and academia. As a practical contribution, the study proposes a set of recommendations to encourage such UFC. The scientific contribution arises from the presentation of a conceptual structure which explores the UFC phenomenon in the teaching context, bringing together the perspectives of collaboration and the co-creation of educational provision, as well as presenting a number of suggestions for future research.

The process of positioning a region is one of the most important tools for attracting investment to a territory. In turn, the methods of work of the human health management system, contributing to the improvement of the quality of life of the population. However, effective tools for positioning the region, which take into account the geographical location, recreational conditions of the territory, the available opportunities, its cultural, national and ethnic identification, as well as differences, have not yet been proposed. This is evidenced by the low level of investment in the regions, the weak development of the real sector of the territory's economy, the rapid decline in the living standards of most of the region's residents, and, as a consequence, the growth in the rate of population migration. Thus, the formation of tools for positioning and identification of the region, which allows you to determine their competitive advantages, is a basic prerequisite for ensuring the economic development of the territory. In modern conditions of the transfer of powers and budgets of state bodies to local governments, the positioning of the region becomes a possible condition for their competitiveness. The article discusses the interpretation of the concept of "positioning", in particular, two of its basic components are highlighted: positioning as a strategy, positioning as a set of actions. Approaches to the positioning of the brand of the region are analyzed, where the region is considered from the position of a unique phenomenon and a complex product with a wide range of properties. The signs of a successful brand are determined, the main goals of branding, assessment, classification of models and stages of positioning the region are highlighted. and also: diagnosis of the situation, formulation of the essence of the brand, a strategic plan for brand promotion. implementation of the strategic plan, assessment of the effectiveness of the formed brand.

Thermal imaging is a promising technology in the medical field. Recent developments in low-cost infrared (IR) sensors, compatible with smartphones, provide competitive advantages for home-monitoring applications. However, these sensors present reduced capabilities compared to more expensive high-end devices. In this work, the characterization of thermal cameras is described and carried out. This characterization includes non-uniformity (NU) effects and correction as well as the thermal cameras’ dependence on room temperature, noise-equivalent temperature difference (NETD), and response curve stability with temperature. Results show that low-cost thermal cameras offer good performance, especially when used in temperature-controlled environments, providing evidence of the suitability of such sensors for medical applications, particularly in the assessment of diabetic foot ulcers on which we focused this study.

Growing Conditions

The red dragon fruit Selenicereus undatus is a native fruit from the Americas. Its growing appeal in the international market as an exotic fruit highlights the relevance of the crop for the local economies. In Colombia, the high diversity within the genus and species makes it difficult to have reliable materials for propagation as cultivars. This agronomic challenge requires more studies of the distribution and real diversity within the genus Selenicereus sp. Due to the information aforementioned, the fruit is harvested in small localities as an extraction production system. This project aimed to morphologically characterize the working collection of red dragon fruit under growing conditions in the Municipality of San Jerónimo. It contained 30 accessions from the departments of Antioquia, Córdoba, and Valle del Cauca. Twenty-one characters of cladode, flower, and fruit were quantified to assess the diversity, and a restricted cluster analysis was performed to understand the morphological richness of the materials. As a result, it was observed differences in terms of stems, such as distance between areolas and width of cladode. This was also observed in flowers, in which their total length, the width of petals, the presence of trichomes, the color of calyx and petals, and the color of the stigma were different. Also, differences were recorded in the fruit. Characteristics such as weight and color of its skin were assessed, resulting in fruit size medium to small. Regarding other properties, total soluble solids varied between 11.2 to 15.6 °Brix. 55% of the fruits have measurements that fit market requirements. Finally, three accessions match the requirements of weight and °Brix, to be used as possible genotypes by commercial growers; however, studies about agronomic management strategies that favor an increase in fruit weight must be done.
