This research aims to know the effect of the Rotor Radius Ratio on the performance of the hybrid Vertical Axis Wind Turbine Savonius-Darrieus NREL S809 model using the Computational Fluid Dynamics method. Two-bladed Savonius is used as an internal rotor, and three-bladed Darrieus NREL S809 as an external rotor. Turbine model performance is analyzed through the value of the Moment Coefficient and Power Coefficient. The result shows that the increase in the Rotor Radius Ratio value causes an increase in the initial M [...]

Improved-Genome editing via Oviductal Nucleic Acids Delivery (i-GONAD) was developed for in situ genome editing of the preimplantation embryos present within the oviductal lumen of mice. This method is based on intra-oviductal instillation of genome editing components and subsequent in vivo electroporation (EP) in the entire oviduct. Therefore, i-GONAD differs from the previous methods (i.e., zygote microinjection and in vitro EP) in producing genome-edited mice, which relied on ex vivo handling of preimplantation [...]

Brain training apps are becoming increasingly popular for at home use and as an adjunct to more traditional therapies. There is uncertainty about whether the effects of brain training transfer to real-world cognition, or performance on other cognitive assessment tests, or is specific only to the brain training app. Executive functions (EF’s) are higher-order cognitive processes important for activities of everyday living and autonomous goal-directed behaviour [1]. EF’s are associated with frontal brain networks tha [...]

Psychiatry is seeking interventions that could reliably sustain weight gain and psychosomatic recovery of patients with severe anorexia nervosa (AN). Currently, patients with AN, even after receiving individually-tailored therapeutic interventions, often relapse following marginal weight restoration. Also, the evidence regarding the effectiveness of psychotropic medications in relieving and treating AN symptomology is limited. The research in the field is aiming to mitigate shortcomings associated with common pract [...]

The main objective of this paper is to study the sustainability of power generation from an abandoned oil and gas well in the province of Alberta, Canada. Economic and environmental indicators were used for the sustainability assessment. A conceptual design for a pilot plant was developed, and the main parameters were determined. An abandoned oil and gas well represents the thermal power source through circulating water into an organic Rankine cycle (ORC) unit to generate electricity. The thermal power is extracted [...]

A core feature of convective geothermal resource production is wellbore energy flow Q ~ ρC x T x V. E.g., for wellbore fluid of volume heat capacity ρC ~ 4.3MJ/m3.oC, temperature T ~ 230oC, and volumetric flow V ~ 50L/s, wellbore heat energy production is Q~ 50MWth ~ 5MWe. Wellbore fluid flow V =2πr0ϕv0ℓ for open wellbore length ℓ is given in turn by the spatially variable product crustal porosity times crustal fluid velocity v ≡ ϕv0 at the wellbore rad [...]

The probabilistic formalism of quantum mechanics is used to quantitatively link the electroencephalogram (EEG) with the underlying microscale activity of cortical neurons. Previous approaches applied methods of classic physics to reconstruct the EEG in terms of explicit physical models of cortical neurons and the volume conductor. However, the multiplicity of cellular processes with extremely intricate mixtures of deterministic and random factors prevented the creation of consistent biophysical parameter sets. To a [...]

This paper aims to introduce a relatively novel approach for Hypnosis to treat Depersonalization-derealization Disorder (DPRD). Depersonalization is conceptualized as a disrupted interoceptive process disorder. Based on this conceptualization, Hypnotic intervention is tailored to counter the flawed process. It is exemplified by a case of a young man suffering from depersonalization disorder who couldn't bear looking at himself in the mirror. The hypnotic intervention used in this case is then explained by predictiv [...]

Infertility affects millions globally, with 10-15% of couples experiencing unexplained cases. Despite advancements in medicine, the cause remains unknown, causing emotional distress. Recent research suggests a genetic basis for this issue. This review aims to provide a better understanding of the underlying genetic factors contributing to unexplained infertility and potentially identify genetic markers that could aid in the diagnosis and treatment of this condition. A literature review was conducted to understand t [...]

The success of tissue transplantation from a healthy donor to a diseased individual (allo-transplantation) is regulated by the immune systems of both donor and recipient. Developing a state of specific non‐reactivity between donor and recipient, while maintaining the salutary effects of immune function in the recipient, is called “immune (transplantation) tolerance”. In the classic early post‐transplant period, minimizing bidirectional donor ←→ recipient reactivity requires the administration [...]
