<i>Opuntia </i><i>ficus-indica</i><i> </i>(L.) Mill., commonly known as prickly pear, is a versatile plant widely used for food, medicinal, and cosmetic purposes in various regions of the Mediterranean and North Africa. This study provides a comparative ethnobotanical review of prickly pear uses in Algeria, Morocco, Tunisia, and Italy. In total, 74 articles were selected from ethnobotanical uses in Italy, Algeria, Morocco and Tunisia. In the Maghreb, the plant is used for fruit production and processed products, such as jams, oils, and flours, as well as for traditional medicinal purposes. In Algeria and Morocco, the fruits and cladodes are used to treat digestive disorders, diabetes, and skin diseases. In Tunisia, products derived from <i>O</i><i>. </i><i>ficus-indica</i> are also applied in the cosmetic industry and for erosion control. In Italy, particularly in Sicily and Calabria, the prickly pear is a vital resource, used for both food consumption and for medicinal purposes. The cladodes, rich in mucilage, are applied as topical remedies for skin problems, while the fruits are a key ingredient in the preparation of traditional desserts. Furthermore, <i>O</i><i>. </i><i>ficus-indica</i> has historically been used as forage and to produce natural dyes. Results indicate that the versatility of this species, combined with its ability to adapt to extreme climates, makes it a valuable resource for the development of new nutraceutical and cosmetic products. However, further scientific research is necessary to explore the bio-functional potential of this plant and to promote its broader and more sustainable use, especially in arid and semi-arid regions.

Thanks to their interesting mechanical properties, recyclability and low production costs, plant fiber-reinforced composites, derived from agricultural residues, are of particular interest to both manufacturers and scientists looking to incorporate new environmentally-friendly and biodegradable materials to replace synthetic fibers, particularly glass fibers. The growing use of these composites in fields such as the automotive, construction and building industries, and soon in aeronautics, raises concerns about the reliability of the structures with which they are manufactured. This reliability must be guaranteed at the design stage, by a good knowledge of the properties of the material used. In this case, for composites, it is necessary to know the mechanical properties of their constituents, fibers and matrix, etc. In this context, this paper focuses firstly on the economic and industrial recovery of Kenaf (K) and Date Palm (DP) fibers, and secondly on their incorporation as a reinforcing element in cementitious matrix composites, for subsequent use in non-structural applications. This research highlights the development of cementitious matrix bio-composites reinforced with this type of fiber, based on Taguchi's statistical methodology, in order to minimize the cost and number of tests. The bio-composites developed are then mechanically characterized under static loading in compression and 3-point bending after a 30-day drying period.

In modern times, a lot of light has been thrown on Information literacy by empirical studies due to its significant role in facilitating access to information and use as well as lifetime learning. It is one of the main factors responsible for the information explosion and a key determining factor for students’ success in academics. The study gauged students’ attitudes on the IL programmes of the University for Development Studies (UDS) using both qualitative and quantitative research approaches. The study discovered that students did not consider the library as a source of academic knowledge and information since their frequency of visiting was low. The study also showed that 43.1% of the respondents go to the library at least once a week while the majority (56.9%) of the respondents either visited the library once a month or not at all. Early Childhood and Basic Education, Development Education, Social Change Communication and Renewable Natural Resources, are the courses pursued by those who utilized the library every day. Alternatively, no student pursuing B. Ed Business Studies made use of the library daily and 48.6% of them did not enter the library at all. The majority (58%) of the respondents had not been oriented on the use of the library. It was realized that 49.8% were knowledgeable of the fact that electronic resources are available in the library. The remaining (50.2%) did not have any knowledge of electronic resources in the library and were unlikely to make use of them. The utilization of electronic resources also varied according to programmes of study. Students who had comparatively higher access to such resources were pursuing Early Childhood and Basic Education. The study also realized that students’ interest in participating in Information Literacy programmes in the university increased and this increased the quality of their information literacy skills. With their awareness and know-how in information literacy, they can use the internet to retrieve the necessary information for academic work. The study makes some recommendations, Principals and Deans should coordinate to organize more Information Literacy Programmes, increased staff participation in the teaching of the IL Programmes and lastly, implementation of Academic Board pronouncements on the IL Programme. This will go a long way to improve access and enhance the use of information in the university.
