Performance in higher education is one of the key expectations of the beneficiaries of training at the University of Burundi. With this in mind, the present study was conducted among 384 students, selected using Cochran’s formula (1977), with the aim of shedding light on students’ perceptions of the training provided by this public institution. The study focused primarily on the organization of academic programs, students’ living and working conditions, the use of ICTs for research and innovatio...

The development of low-cost and environmentally friendly solar cell technologies has attracted significant attention as an alternative to traditional silicon-based devices. Carbon dots (CD_s), owing to their tunable optical band gap, strong absorption in the visible spectrum, and excellent electron-donating properties, have emerged as promising sensitizers and interfacial modifiers in solar energy conversion systems. In this study, we present a systematic investigation of CD_s...

Background: Implant breakage following Intramedullary (IM) nailing of long bone fractures is an uncommon but potentially catastrophic complication that often necessitates complex revision surgery. Robust estimates of its incidence and predictors are needed to guide surgical planning and postoperative management. Methods: PubMed and Google Scholar were systematically searched for studies published between January 2005 and December 2024 reporting IM nail breakage ...

Periodontal diseases, stemming from microbial imbalances and chronic inflammation, represent a significant global health challenge. While traditional mechanical debridement forms the cornerstone of treatment, adjunctive therapies are often necessary to achieve optimal and lasting periodontal health. This literature review evaluates the current evidence on probiotics as an adjunct to initial periodontal treatment, focusing on their efficacy in improving clinical parameters and modulating the oral...

Cistanche tubulosa (CTE) aqueous extract is already employed as a botanical prescription drug for treating dementia in China. CTE, derived from dried C. tubulosa stems, is freshly prepared with sterile distilled water. CTE requires acute and chronic toxicity studies to ensure its safety in clinical applications. This study evaluates the safety profile of CTE through both in vitro and in vivo tests. Ames tests conducted on five strains of Salmonella typhimu...

Background: Collagenous Fibroma (CF) of the nail, particularly the finger, is exceedingly uncommon. Although uncommon, they should be included in the differential diagnosis of nail abnormalities. Early diagnosis and complete surgical excision lead to an excellent prognosis with a minimal risk of recurrence. Objective: To raise awareness of the rarity of this condition to improve its early diagnosis and management. Case Report: A 72-year-old woma...

The research on the main controlling factors of tight oil has always been the core content of unconventional oil and gas geology theory. Taking the tight oil of Chang 81 reservoir group in W105 area of Nanliang Oilfield in Ordos Basin as the research object, the characteristics of reservoir sand body thickness, lithology, reservoir space and physical properties were analyzed by using logging, mud logging, core, mercury injection and oil test data. The type of Chang 81 reservoir was clarified, an...
