Digital Twin
Digital Twin: Above is an image from the digital twin (DT) of BMW’s factory in Regensburg, Bavaria, created in NVIDIA’s Omniverse. There are two versions of a BMW factory in the medieval town of Regensburg, Germany. One is a physical plant that cranks out thousands of cars a year. The other is a virtual 3-D replica, accessed by screen or VR headset, in which every surface and every bit of machinery looks exactly the same as in real life. Soon, whatever is happening in the physical factory will be reflected inside the virtual one in real time: frames being dipped in paint; doors being sealed onto hinges; avatars of workers carrying machinery to its next destination. The latter factory is an example of a “digital twin”: an exact digital re-creation of an object or environment. The concept might at first seem like sci-fi babble or even a frivolous experiment: Why […]
MUCORMYCOSIS
Mucormycosis: (Previously called zygomycosis: misnomer black fungus) _ _____ Section-1 Prologue: Fungi are important to everyday human life. Fungi are important decomposers in most ecosystems. Mycorrhizal fungi are essential for the growth of most plants. Fungi, as food, play a role in human nutrition in the form of mushrooms, and also as agents of fermentation in the production of bread, cheeses, alcoholic beverages, and numerous other food preparations. Secondary metabolites of fungi are used as medicines, such as antibiotics and anticoagulants. Fungi are model organisms for the study of eukaryotic genetics and metabolism. Fungi are relatively uncommon causes of disease in healthy and immunocompetent human hosts, even though hosts are constantly exposed to infectious propagules. However fungal diseases have occurred originating from opportunistic and pathogenic fungi. Opportunistic fungi have a preferred habitat independent from the living host and cause infection after accidentally penetration of intact skin barriers, or when […]
COMPLEMENTARY AND ALTERNATIVE MEDICINE
COMPLEMENTARY AND ALTERNATIVE MEDICINE: Prologue: A well educated and qualified doctor from western country practiced in an underdeveloped tribal area of an African country full of quacks and god-men but became very popular. When asked how such a scientific and rational doctor became popular among tribal, he gave a simple answer. He said that one third of patients are psychic, another one third have self limited illnesses and the remaining one third have illnesses which need his attention.

This is the difference between the conventional scientific medicine and traditional unscientific medicine. Thousands of years ago everybody believed that the sun revolves around the earth & the earth is stationary but today, everybody believes that the earth revolves around the sun & rotates on […]
