Similar health emergencies, different commitments: Comparative strategies to end Ebola and COVID-19 in "post-conflict" Liberia.

Liberia, in the face of two consecutive health emergencies - the Ebola epidemic in 2014 and COVID in 2019 - offers a unique, comparative perspective on health crisis management within a fractured healthcare system. In dialogue with a feminist-informed political economy of health in the African context, this paper has two central objectives. First, it examines the strategies employed by community-based women's organisations - many of whom remain invested in peacebuilding after a 14-year civil war (1989-2003)) - to contain the Ebola and COVID-19 disease outbreaks.

Microplastic pollution along the coastal island shorelines of Bangladesh: Distribution, patterns, and abundance.

Microplastics (MPs), less than 5 mm in length, have become a major environmental issue due to their hazardous physical and chemical properties. The research investigated 54 sediment samples collected from three different zones of the beaches, namely the wrack line, beach face, and swash zone. This study aims to enumerate the number and polymeric variety of microplastics found in beach sediments from coastal islands of Bangladesh, including Sandwip, Kutubdia, and Saint Martin's Island in the northeastern Bay of Bengal.

Surgical Management of Adult Spinal Deformity Patients with Osteoporosis.

Adult spinal deformity (ASD) commonly affects older adults, with up to 68% prevalence in those over 60, and is often complicated by osteoporosis, which reduces bone mineral density (BMD) and increases surgical risks. Osteoporotic patients undergoing ASD surgery face higher risks of complications like hardware failure, pseudoarthrosis, and proximal junctional kyphosis (PJK). Medical management with antiresorptive medications (e.

Welding of S960QL High-Strength Steel by the Manual-Automated MAG Technique-A Study of Mechanical Properties, Residual Stresses and Fracture Mechanisms in the Heat-Affected Zone.

This paper presents results of investigations of a V-type welded joint made of S960QL high-strength steel made using a mixed technique: the root was welded manually and the face automatically. Although high-strength steels have been available on the market for many years, they are still the subject of research due to their increasingly widespread usage. For this reason, detailed investigations of welded joints of S960QL steel were carried out in terms of microstructure, microhardness, impact toughness and residual stresses, in order to expand knowledge in this area.

Bacteria-Powered Self-Healing Concrete: Breakthroughs, Challenges, and Future Prospects.

In a world where concrete structures face constant degradation from environmental forces, a revolutionary solution has emerged: bio-self-healing concrete. This innovation involves embedding dormant bacteria within the concrete mix, poised to spring into action when cracks form. As moisture seeps into the cracks, these bacterial agents are activated, consuming nutrients and converting them into calcium carbonate, a natural substance that fills and repairs the fractures, restoring the material's integrity.

Poor bone health in Duchenne muscular dystrophy: a multifactorial problem beyond corticosteroids and loss of ambulation.

Duchenne muscular dystrophy (DMD) is a progressive, fatal muscle wasting disease caused by X-linked mutations in the dystrophin gene. Alongside the characteristic muscle weakness, patients face a myriad of skeletal complications, including osteoporosis/osteopenia, high susceptibility to vertebral and long bone fractures, fat embolism post-fracture, scoliosis, and growth retardation. Those skeletal abnormalities significantly compromise quality of life and are sometimes life-threatening.

Spatiotemporal evolutions of gas pressures in coal seam during gas extraction under mining disturbance.

A 3D geometric model is established based on a fluid‒solid coupling model for purpose of identifying the influences of mining disturbances on the distribution of gas pressures in front of a working face during gas extraction. Then, the stress distribution and gas extraction process are simulated using COMSOL software. The spatiotemporal evolutions of gas pressures in front of the working face are analyzed from the dimensions of point, line, surface, and volume.

Risk classification assessment and early warning of large deformation of soft rock in tunnels based on CNN-LSTM model.

Tunnels in the Western Plateau region of China often face numerous problems of high ground stress, as well as highly fractured and weak rock masses in deep sections of the tunnel, which results in an increased risk of large soft rock deformation in tunnels, posing substantial challenges to safe and efficient construction. Hence, risk assessment and establishment of an early safety warning system are essential. By examining factors affecting the large soft rock deformation in tunnels, a set of index system consisting of three primary indicators (i.

Background: Total knee arthroplasty (TKA) is a crucial orthopaedic procedure used to relieve pain from knee joint degeneration. Concurrently, peripheral artery disease (PAD) presents a major challenge, complicating orthopaedic interventions, particularly TKA, due to its impact on vascular health. Despite advances in surgical techniques and care, patients who have PAD undergoing TKA face heightened risks.

Experimental Analysis of Gas Injection Feasibility and Evaluation of Enhanced Recovery Potential in Mahu Tight Conglomerate Reservoirs.

A series of development technologies of "horizontal well plus volume fracturing" have been established to achieve an annual output of one million tons of crude oil in 7 the Mahu tight conglomerate reservoir. However, such oil fields generally face problems such as rapid pressure drop, rapid production decline, difficulty in water injection, and gas channeling, seriously affecting the beneficial development of tight conglomerate reservoirs. To solve these problems, in this study, we carried out the feasibility experiment of different gas injection developments and the potential evaluation of enhanced oil recovery based on the combination of laboratory experiments and numerical simulation.
