Large-Area Transfer of Nanometer-Thin C Films.

Fullerenes, with well-defined molecular structures and high scalability, hold promise as fundamental building blocks for creating a variety of carbon materials. The fabrication and transfer of large-area films with precisely controlled thicknesses and morphologies on desired surfaces are crucial for designing and developing fullerene-based materials and devices. In this work, we present strategies for solid-state transferring C molecular nanometer-thin films, with dimensions of centimeters in lateral size and thicknesses controlled in the range of 1-20 nm, onto various substrates.

Pure tone and speech audiometry of presbyacusis in a tertiary hospital in Kaduna, Nigeria: a cross-sectional study.

Introduction: presbyacusis is age-related hearing loss, manifesting as a bilateral symmetrical sensorineural hearing loss of adult-onset. It has different audiometric configurations and is associated with a decline in speech discrimination sensitivity. The objectives of the study were to determine the degree of hearing loss; types of presbyacusis; and speech discrimination score (SDS) of presbyacusics and to compare the SDS in different types of presbyacusis in patients seen at a tertiary hospital in Kaduna, Nigeria.

3D Microporosity Characterizations in the Heterogeneous Middle Jurassic Tuwaiq Mountain Formation: Insights into an Unconventional Sweet Spot.

Carbonate microporosity can vary significantly across depositional lithofacies and cycles, owing primarily to the high degree of heterogeneity in their pore sizes, pore throat radius, geometry, and connectivity. This is further compounded by the complex diagenetic alterations during various stages of burial. In addition, the presence of micropores, which are abundant in carbonate rocks, but not visible using conventional techniques, is challenging to characterize.

Prevalence and Pattern of Hearing Loss among Young Adults in Tertiary Institutions with Habitual Headphone/Earphone Usage in Kaduna Metropolis.

Background: World Health Organisation estimates that 1.1 billion young people worldwide could be at risk of hearing loss due to unsafe listening practises and nearly half of the teenagers and young adults are exposed to unsafe levels of sound from the use of personal audio devices.

Aim: This study aimed to determine the prevalence and pattern of hearing loss among students with habitual use of headphone/earphone in tertiary institutions in Kaduna.

Improving Program Outcomes Through Responsive Feedback: A Case Study of a Leadership Development Academy in Nigeria.

Background: In 2018, the National Primary Health Care Development Agency (NPHCDA), under the Nigeria Federal Ministry of Health, recognized that inadequate personnel competencies limited its ability to provide technical assistance to state primary health care development boards (SPHCBs). In response, NPHCDA instituted a cohort-based leadership development academy (LDA) to develop its staff's leadership and management skills.

Nphcda Leadership Development Academy Program: A baseline assessment identified critical gaps in leadership and management competencies.
