Thermoplastics polymers like Acrylonitrile Butadiene Styrene (ABS) are often reinforced with nano/micro reinforcements to enhance their mechanical, thermal and electrical properties. However, the viscoelastic nature of these polymers results in their strong dependence on the applied strain rate and temperature sensitivity, leading to their characterization complexity. Hence it is paramount to study the strain rate-dependent mechanics of neat ABS. In this study, the effect of strain rate and temperature on Young’s m [...]

Most children do not meet physical activity guidelines, and school-based programs often fail to increase physical activity levels. However, there has been no intervention pairing college mentors with elementary students to date. The purpose of this paper is to report the feasibility and acceptability, both quantitative and qualitative, of an undergraduate-mentored running program designed to increase physical activity in elementary students. A convergent parallel mixed methods design was used to evaluate the feasib [...]

Genetic diversity allows plants to adapt to changing environmental conditions to survive and increases their ability to respond to yield, production, pests and diseases. The application of molecular markers developed due to developments in biochemistry, molecular biology, and plant technology has shed light on plant genetics and breeding studies and produced an enormous amount of knowledge. The theoretical knowledge will guide in determining the scope, amount, and distribution of different aspects of genetic divers [...]

Hematopoietic stem cell transplant (HSCT) recipients are at an increased risk of bacterial, viral, fungal and parasitic infections. Past exposures to infections, the degree of immunosuppression, prolonged neutropenia and presence of graft versus host disease (GVHD) are some of the factors which make HSCT recipients more susceptible to infections. Viral infections have emerged as a major challenge causing high morbidity and mortality in stem cell transplant recipients. Myeloablative conditioning regimens and GVHD pr [...]

The population of the United Kingdom is ageing. In 2017 approximately 18% of the UK population were aged 65 years or over and projected to grow to almost 21% by 2027 according to the Office of National Statistics. Increased age is the greatest risk factor for developing dementia. It is estimated that there are 850,000 people living with dementia in the UK and if current figures relating to incidence and prevalence are realised, this will increase to 1 million people by 2025 and 2 million by 2051. The National Healt [...]

Left ventricular assist devices (LVADs) improve quality of life in end-stage heart failure patients but a frequent complication is Right heart failure (RHF) causing significant morbidity and mortality. This review article discusses key issues that need to be considered in the assessment and clinical management of RHF in LVAD patients including the use of Right Ventricle (RV) support devices and off-label LVADs as temporary or permanent RV support.

Fischer-Tropsch reactors operated in a steady state suffer from a low pore effectiveness factor and a high methane selectivity caused by internal mass transfer limitations due to the accumulation of long-chain hydrocarbons inside the catalyst pores. Therefore, an alternating process switching between Fischer-Tropsch synthesis (FTS) and drainage of the pores by hydrogenolysis is proposed. The periodical cracking of the accumulated waxes within the (partially) filled pores, realized by a switch from syngas (H2, CO) t [...]

CO2 reforming of CH4, also referred to as the Dry Reforming of Methane (DRM), is considered an excellent method to produce H2 and CO (syngas), which are known to be used for the production of higher alkanes and oxygenates. Despite nickel’s moderate toxicity, Ni-based heterogeneous catalysts are considered excellent candidates for use in DRM due to their reasonable performances and economic advantages. However, these materials also present severe drawbacks, such as sintering of the active phase and coke (carbo [...]

Background: Fluorescence In Situ Hybridization (FISH) has become routine for bio-medical research and medical diagnosis, thereby offering a variety of probes and ready-to-use kits that fulfil requirements for many applications. However, conventional FISH relies on chemical and/or thermal denaturation to improve target accessibility and uses huge amounts of DNA that needs to be bonded to the target site. COMBinatorial Oligo-nucleotide FISH (COMBO-FISH) offers possibilities to circumvent these shortcomings. Methods: [...]

Background: This study investigated variations in psychic and somatic anxiety during and after completion of MBCT compared to baseline in patients diagnosed with BD. Secondary variables considered were sleep quality and quality of life, as well as depressive and manic symptoms. Methods: HAMD-29, HAMD-7 and YMRS were administered at baseline (n=34), and every two weeks until the end of the eight-week program. PSQI (n=22) and Q-LES-Q-SF (n=29) were also administered at pre, mid- and post- MBCT assessments. Results: T [...]
