Students’ Approaches to Learning (SAL) theory assumes that the deep approach generates better academic performance when compared to the surface approach. This study tests this hypothesis, using a randomized experimental design of pre- and post-test case-control. Students in a discipline of a biology course were randomly allocated to the experimental and control groups. The experimental group carried out a pedagogical activity which aimed to mobilize the deep approach, while the control group performed a mobilizing activity with a surface approach.

The pandemic state, declared by the World Health Organization, on March 11, 2020, has tested society's adaptability and response. A race against time to seek strategies to fight the disease of the new coronavirus contributes to the union of scientists from all over the world, including using nanotechnology Thus, the objective of the study was described the landscape of nanotechnology strategies against COVID-19,highlighting mainly the products and diagnostics, vaccines and treatments that are or can be used.

This article is characterized as a critical study of the discourse of increasing competence in the educational field, specifically in the 1990s. The concept reveals a transition from qualified training to competent training, characterized as flexibility and mobilization of knowledge to perform tasks. The objective was to develop in the discourse analysis of education the historical restructuring of competence.

The purpose of this study was to examine the various benefits tomato and Irish potato participants (farmers) get from extension and advisory services (EAS) in the West Region of Cameroon. The sample under survey consisted of 210 farm households of those who benefited from EAS. Data was generated from primary and secondary sources and were analysed through descriptive and inferential statistical technique using Statistical Package for Social Sciences and Micro Soft Excel.

The use of high-quality seeds is a premise for the implantation of pasture under sustainable farming systems to livestock production. The usual practice is to mix Urochloa seeds with nitrogenous to use these inputs. The objective of this study was to evaluate the effect of contact time (0, 3, 6, 12, 24, 48, and 72 hours) and amounts (50, 100, and 150 kg N-1) of urea on Urochloa brizantha seeds physiological quality. A completely randomized experimental design was used, with three replicates. Seedling emergence, germination of normal and abnormal seedlings, and dead seeds were evaluated.

Building a resilient community is very pertinent since no community is immune from disaster both natural and man-made. The novel Coronavirus Disease (Covid-19) pandemic is one of such disaster that has affected most countries of the world, including Nigeria. This study highlighted the significant impact of this pandemic on the economic, health and educational systems of the country. The study further discussed several strategies which could be applied to build resilient communities in Nigeria even in the face of Covid-19.

Background: Ibandronate sodium is used for the clinical treatment of osteoporosis and in having anti-catabolic action it improves bone structure, bone mineralization, bone fracture healing, mechanical fixation and osseointegration of implants in animal models. The objective of this study was to assess the effect of ibandronate sodium in the consolidation of rat femoral fractures subjected to intramedullary osteosynthesis. Methods: Forty-eight male, adult Wistar rats were used in the study, randomly distributed in two groups (ibandronate and control).

Remanufacturing is a process whereby value from old products is recovered by replacing and recovering used components to bring such products to a new or like-new state. Today, both original equipment manufacturers (OEMs) and third parties are engaged in remanufacturing activities .However, the supply chain sourcing in remanufacturing operations is more complex than traditional manufacturing due difficulty establishment of a sorting policy and the uncertainties associated with the quality, quantities and return timing of used products and components.

Pearl millet (Pennisetumglaucum (L.) R. Br) is a cereal grown in the driest tropical and subtropical regions of Africa and Asia. Thanks to its strong capacity to adapt to the dry tropical climate and low fertility soils, millet plays an important role in the food security of local populations in these regions. It is able to establish a mycorrhizal symbiosis with arbuscular mycorrhizal fungi (AMF), which play a key role in the absorption of nutrients and the mitigation of abiotic and biotic stress in their host.
