Rhodamine (RhB) adsorption was carried out on MCM-41 and MCM-41 calcined. The effect of parameters such as pH was investigated. The reusability potential of MCM-41 was also established and the mechanism of RhB adsorption was discussed. MCM-41 was synthesized and calcined, with all samples characterized by X-Ray Diffractometry, X-ray Fluorescence by Dispersive Energy, Infrared Spectroscopy, Scanning Electron Microscopy, and Thermogravimetric analysis. The results of the characterization techniques performed confirme [...]

Aneurysmal subarachnoid hemorrhage (aSAH) causes serious brain injury, and its mechanisms have not been completely unraveled so far. The causative factors for the brain injury initiated by an aneurysm rupture, which is referred to as the early brain injury (EBI), include elevated intracranial pressure, cerebral hypoperfusion, and blood contents that are directly exposed to the brain surface. At Day 4–14 post aSAH, delayed cerebral ischemia (DCI) often develops, which may worsen the neurological outcomes critically. [...]

The research described the production and characterization of various materials, particularly alpha-alumina ceramic supports, zeolite SAPO-34, and zeolite membranes. Ceramic supports were manufactured through dry uniaxial compaction. Sintering of the supports was carried out at 1300°C for 2 h. SAPO-34 zeolites and zeolite membranes were synthesized through a hydrothermal process involving two steps: a first step at 38°C for 24 h and a second step at 200°C for 24 h. The research aimed to determine how different sili [...]

The Cobb angle is traditionally used for quantifying the degree of spinal curvature through evaluation of the full spinal cord. When conducting measurements on videofluoroscopy swallowing studies (VFSS), the Cobb angle can measure degree of cervical vertebrae curvature, which may have implications for swallowing. Given that this measure may have utility in dysphagia research, the reliability of this measure taken from C2-C4 and establishing the presence of changes with age were the focus of the current, proof-of-pr [...]

Myokines are cytokines secreted from muscle during contraction and are implicated in autocrine, paracrine, and endocrine regulation of biological systems. It is postulated that myokines contribute to skeletal muscle adaptations in response to resistance exercise. Exercise, including resistance exercise, is an important factor in the management of maintaining skeletal muscle strength, mass, and function with aging. Sarcopenia is exacerbated with increased age and therefore, it is important to understand the potentia [...]

Background: The increasing numbers and proportion of the ageing population make it essential to develop and evaluate programs to meet the needs of older adults to empower them to age actively, healthily and successfully. Consequently, positive ageing programs have been developed and the need to evaluate their outcomes is essential. This study used mixed methods to evaluate cognitive and behavioural changes and to monitor psychological health and active ageing in participants of a longstanding positive ageing psycho [...]

To increase the amount of information on the intensities of tropical cyclones (TC) used in climate research, the possibility of additional estimates of the intensity of a TC by exploring historical data of conventional (non-Doppler) airborne and coastal radars is considered. Based on the hyperbolic-logarithmic spiral (HLS) model of the streamline in the TC, an assessment of the maximum wind speed in hurricanes Cleo (1958), Carolina (1975) and Alicia (1983) was made. Literature sources containing radar signatures of [...]

Genito-Pelvic Pain Penetration Disorder (GPPPD) affects between eight and twenty percent of women. There is recent evidence that compassion focused therapy (CFT) can help those with general health conditions and persistent pain. This study aims to investigate application of CFT techniques to an existing psychosexual therapy group of women with GPPPD and establish an effect size that could be used in a fully powered trial in future. The study took place within a routine clinical setting. Women who attended a group w [...]

Hybrid composites based on inorganic nanomaterials embedded into a polymer matrix have were synthesized and characterized. Oxide semiconductor nanoparticles (SnO, SnO2, TiO2, Ga2O3, and NiO) and Si nanoparticles were employed as inorganic counterparts in the hybrid composite, while a conductive polymer (PEDOT:PSS) with diverse additives was used as the organic matrix. The composites were spin-coated on Si or glass substrates. The potential use of these materials in photovoltaic devices to improve Si surface passiva [...]

Consensus for where along the eating disorder spectrum the pathological eating behaviour of Chew and Spit (CHSP) falls has been a point of contention in academic literature. Using the case of Mary1, a 30 year old female from Australia who has engaged in excessive restrictive behaviour, was diagnosed with anorexia nervosa (AN) and has been engaging in Chew and Spit (CHSP) behaviour for over 10 years, the current paper examines the similarities from a neurobiological perspective between restrictive behaviours (akin w [...]
