    Nietzsche: Dionysian-Apollonian Lord of the Dance

    Get PDF
    Friedrich Nietzsche introduced his philological study of the Ancient Greek\u27s Apollonian and Dionysian duality in his first book, The Birth of Tragedy: Out of the Spirit of Music, in 1872. His interpretation of the two Greek gods underpinned his philosophy of the will to power, the Ăśbermensch, and eternal recurrence throughout his career. I contend that Nietzsche\u27s philosophy would have a modicum of merit as a metaphor for Greek culture and the German society in which he lived if his underlying assumption about atheism was correct. However, his explicit rejection of Christianity led to a fatal flaw in his reasoning because the Christian God\u27s existence can be rationally defended as the inference to the best explanation in an Apollonian manner. Yet, Christians also experience a Dionysian life-affirming existential encounter with the Living God. Jesus declared, I am come that they might have life, and that they might have it more abundantly. Nietzsche proclaimed that he would only believe in a God who can dance. Christianity is both a rational system of beliefs and an exciting encounter with God. Jesus is the Lord of the Dance

    A Kantian View of Transgenderism

    The recent popularity of sex reassignment surgery is logically untenable and immoral when understood in the light of Kantian philosophy. From a Kantian perspective of synthetic a priori judgments, I argue that a biological male cannot rationally claim to “feel like a woman inside.” As a male, any female is part of the noumenal world and cannot be known apart from perception. The statement “I feel like a woman inside” assumes all women feel the same on the inside. Kant’s explanation of the noumenal and phenomenal excludes the possibility of knowing that all women or men feel the same inside because it is impossible to know the noumenal world or the thing in itself. I argue that Kant’s moral principle of universality would conclude sex reassignment surgery would lead to contradictions and absurdities. If all men everywhere universally had the operation to look like their perception of a female, the end of the human race would soon follow; therefore, a Kantian would conclude sexual reassignment surgery is immoral

    Molten pool modeling, microstructure and grain refinement in Ti-alloys

    It is known that titanium alloys are widely used in a variety of industries such as aerospace, automotive and biomedical. Good corrosion resistance and the high strength/weight ratio are among the properties that have made these alloys attractive for abovementioned industries. Although these alloys have been extensively investigated for the past decades, the growing demand, the high cost and the recent development of additive manufacturing techniques require better understanding of these alloys as well as the existing relationship between composition, processing and properties. The approach here is to model the molten pool dynamics, created during additive manufacturing processing of titanium alloys, via Comsol Multiphysics to assess key aspects such as grain growth direction and cooling rates. The Laser Engineered Net Shaping (LENS™), was used to produce a set of specimens to evaluate microstructure and grain refinement in the Ti-W system. The computational results indicate the importance of are the fluid dynamics variables (e.g. Marangoni and buoyance effects) and the preferential grain growth in the \u3c001\u3edirection. A compositionally graded titanium binary system (Ti-xW specimen (0≤x≤30 wt%) was used to evaluate the influence of composition on grain refinement by applying the Easton & St. John model that shows how the grain refinement is mainly governed by the nucleant particles mechanism. In addition, a set of nine Ti-6wt%W specimens were deposited using LENS™ with different laser energy densities and the results shows how the energy density is proportional to the grain size due to two effects. The first effect is that as the energy density increases, the potential availability of nucleant particles can be reduced. Second the energy density (represented by power in the model) is inversely proportional to the cooling rate which confirms the proportionality between grain size and energy density

    System Modeling of Brain-Neuromuscular Functions for Developing Brain-Computer Interface

    Get PDF
    Brain-computer interface (BCI) has been developed for the purpose of bypassing the spinal cord and peripheral nervous system to communicate or control a remote device. Prospective designs have claimed to be able to assist people with severe disabilities or apply to the practice of neurorehabilitation. Nonetheless, due to the complicated and unpredictable nature of such systems, the feasibility and reliability of available BCIs remain to be fully explored. In this study, we applied system identification techniques for black-box modeling, attempting to find the most appropriate BCI system model

    Magnetic Induction Wand Design for Novel Penile Prosthesis​

    Get PDF
    Uronext LLC designed a novel penile prosthesis made of the shape change alloy nitinol for men who suffer from erectile dysfunction. The optimal way to induce the shape change in the prosthesis is by applying heat through induction heating. Existing induction heaters are too heavy and too powerful to safely and effectively heat the Uronext implanted penile prosthesis. An induction heating wand was made to combat this issue and provide a more appropriate induction heating device. A test bench was designed to test the effectiveness of the wand on the prosthesis

    Glucose self-monitoring: Think twice for type 2 patients

    Stop routinely recommending blood glucose self-monitoring for patients with newly diagnosed type 2 diabetes. Self-monitoring does not improve glycemic control for patients who are not taking insulin, and it increases the risk of depression. Stength of recommendation: B: Single well-done randomized controlled trial (RCT)

    Mitochondrial Inheritance in Phytopathogenic Fungi—Everything Is Known, or Is It?

    Get PDF
    Mitochondria are important organelles in eukaryotes that provide energy for cellular processes. Their function is highly conserved and depends on the expression of nuclear encoded genes and genes encoded in the organellar genome. Mitochondrial DNA replication is independent of the replication control of nuclear DNA and as such, mitochondria may behave as selfish elements, so they need to be controlled, maintained and reliably inherited to progeny. Phytopathogenic fungi meet with special environmental challenges within the plant host that might depend on and influence mitochondrial functions and services. We find that this topic is basically unexplored in the literature, so this review largely depends on work published in other systems. In trying to answer elemental questions on mitochondrial functioning, we aim to introduce the aspect of mitochondrial functions and services to the study of plant-microbe-interactions and stimulate phytopathologists to consider research on this important organelle in their future projects
