ORNAMENTAL PLANTS FROM THE COMMELINACEAE AND PIPERACEAE FAMILIES EXISTING IN THE GREENHOUSES OF THE BOTANICAL GARDEN "AL. BUIA" FROM CRAIOVA

Greenhouses of the Botanical Garden "Al. Buia" in Craiova house a varied collection of plants, belonging to numerous families. In this paper, species from the families Commelinaceae and Piperaceae are presented. The family Commelinaceae includes herbaceous plants, rarely lianas, native to tropical and temperate regions of the world, except Europe. In the greenhouse, this family is represented by ornamental species of the Callisia, Cyanotis and Tradescantia genera. The family Piperaceae comprises herbaceous plants, subshrubs or lianas, rarely trees, with simple, entire leaves, with stipules, often succulent and with small, bisexual or unisexual flowers, grouped in spikes or spadix. They are plants that grow spontaneously in tropical or subtropical areas around the world, but the greatest diversity is found in the Americas in a wide range of habitats being distributed from the southern United States of America to Chile and Argentina. In the greenhouses of the Botanical Garden this family is represented by two genera: Piper and Peperomia. In addition to the decorative effect, numerous representatives of the Piperaceae family are used as a food ingredient (Piper longum, Piper nigrum, Peperomiapellucida) and in traditional medicine to treat a wide variety of conditions: inflammatory diseases, gastrointestinal and respiratory tract disorders, acne, kidney diseases. Therefore, disseminating information about the existing ornamental plants in the greenhouses of the Botanic Gardens on the one hand supports their botanical value and on the other hand represents another step for environmental education

Scenarios of developing private brands for food products

Private brands are those manufactured or provided by one company for offer under another company's brand. They are often positioned as lower-price alternatives to national brands, and they are helping retailers to build sustainable relationships with their customers. The objective of this research is to identify the main directions of developing private brands for food products. Pursuing this, a documentary study was carried out, analyzing the situation of using private brands on different markets around the world. Research findings showed that private branding strategies differentiate themselves depending on the type of market: developed markets and emerging markets. In developed markets, there are great opportunities for development of premium segments, with top quality products and higher price, which gives the chance for higher differentiation of retailers and increased loyalty. In emerging markets, private label products have great potential, growing together with retail modernization and consolidation. These results are useful for retailers in their efforts to decide strategies for their private brands

COLLECTION OF USEFUL PLANTS IN GREENHOUSES BOTANICAL GARDEN OF THE UNIVERSITY OF CRAIOVA

Botanical Gardens are responsible for ensuring optimum plant growth and to present them to the public.This paper presents data on useful plants from different geographical regions grown in greenhouses of the Botanical Garden of the University of Craiova. Are presented the data on taxonomic classification, origin, use, part(s) used. These species are edible fruit gives us: Persea americana (Avocado), Eriobotrya japonica (Japanese medlar), which provides textile plants: Boehmeria nivea (Ramie), plants used in food: Manihot esculenta (Cassava), Olea europaea (Olive), Citrus spp., plants with stimulant, aromatic and therapeutic properties: Coffea arabica (Coffee tree), Piper nigrum (Black pepper), Vanilla planifolia (Vanilla), Cinnamomum camphora (Camphor tree), Myrtus commmunis (Myrtle), many of species entered the plants fail to reach flowering and fruiting

UNLOCKING CUSTOMER SENTIMENT INSIGHTS WITH AZURE SENTIMENT ANALYSIS: A COMPREHENSIVE REVIEW AND ANALYSIS

The paper analyzes the accuracy of the Azure Sentiment Analysis service for five languages, namely Romanian, French, Italian, Portuguese, and Spanish. The study generated 300 texts for each language type expressing positive and negative sentiments with varying lengths (less than 100 characters, between 100 and 250 characters, and more than 250 characters). The Azure Sentiment Analysis Review custom-made application was developed using C# language with .NET Framework and Entity Framework for the Microsoft SQL database, and it is used to make a request to the Azure Sentiment Service, and the response sets the label into the database. The expected and Azure labels for each type of analyzed text were described as well. The accuracy of sentiment recognition for different languages and text lengths is presented in the form of statistics, with the global accuracy of the service being 81.8%. The challenges of accurately classifying the sentiment of short and long texts were highlighted. The results suggest that texts of moderate length are easier to classify

Actinide covalency measured by pulsed electron paramagnetic resonance spectroscopy

Our knowledge of actinide chemical bonds lags far behind our understanding of the bonding regimes of any other series of elements. This is a major issue given the technological as well as fundamental importance of f-block elements. Some key chemical differences between actinides and lanthanides—and between different actinides—can be ascribed to minor differences in covalency, that is, the degree to which electrons are shared between the f-block element and coordinated ligands. Yet there are almost no direct measures of such covalency for actinides. Here we report the first pulsed electron paramagnetic resonance spectra of actinide compounds. We apply the hyperfine sublevel correlation technique to quantify the electron-spin density at ligand nuclei (via the weak hyperfine interactions) in molecular thorium(III) and uranium(III) species and therefore the extent of covalency. Such information will be important in developing our understanding of the chemical bonding, and therefore the reactivity, of actinides

Sustainable Consumption: Analysis of Consumers’ Perceptions about Using Private Brands in Food Retail

Private brands are representing an important vector for retailers, helping them to build sustainable relationships with their customers. Usually, private brands are perceived as products differentiated by lower prices. The purpose of this research is to identify consumers’ trust level in private brands used in food retail and their perceptions about the quality of retailers’ own products. The research question is: What are consumers’ perceptions about using private brands in food retail? Pursuing this question, a survey based on a questionnaire was carried out. Research findings showed that the main reason why people buy private brands’ products is lower price rather than high quality. The interviews showed that the typical private brand user is male, aged between 45 and 65 years old, with middle-level income, and employees with secondary education. These results are useful for retailers in their efforts to decide strategies for their private brands and for building consumers’ trust. The findings are useful for food producers as well, because they should reconsider their marketing strategies in order to adapt themselves to the continuous growth of retailers’ private brands
