The Srotas, besides performing numerous functions at both macroscopic and microscopic level, which when gets disrupted, causes pathological features; hence it is immensely required to understand the physiological and pathological concepts of srotas. Generally srotas are considered only at gross level, as structures, carrying material. But the concept of srotas is very deep and minute, which can be explained with the help of cell adaptation concepts, explained by the modern science. This article shall be helpful in putting forth the ayurvedic perspective of srotas along with modern pathological considerations.

Duchenne muscular dystrophy is a genetic disease with a sex-linked pattern of inheritance. This disease is present at birth, becomes symptomatic during early childhood, leads to inability to walk near the end of the first decade, and usually results in death by the end of the second decade. In this study, the extensor digitorum longus and soleus muscles from genetically dystrophic mice were examined at the electron microscopic level. The authors describe their results and discuss how these findings might provide some insight into one of the mechanisms of fiber necrosis in Duchenne muscular dystrophy.

Type 3 macular neovascularization (MNV3), or retinal angiomatous proliferation (RAP), is a distinct type of neovascular age-related macular degeneration (AMD), which is a leading cause of vision loss in older persons. During the past decade, systematic investigation into the clinical, multimodal imaging, and histopathological features and therapeutic outcomes has provided important new insight into this disease. These studies favor the retinal origin of MNV3 and suggest the involvement of retinal hypoxia, inflammation, von Hippel–Lindau (VHL)–hypoxia-inducible factor (HIF)–vascular endothelial growth factor (VEGF) pathway, and multiple cell types in the development and progression of MNV3. Several mouse models, including the recently built Rb/p107/Vhl triple knockout mouse model by our group, have induced many of the histological features of MNV3 and provided much insight into the underlying pathological mechanisms. These models have revealed the roles of retinal hypoxia, inflammation, lipid metabolism, VHL/HIF pathway, and retinoblastoma tumor suppressor (Rb)–E2F cell cycle pathway in the development of MNV3. This article will summarize the clinical, multimodal imaging, and pathological features of MNV3 and the diversity of animal models that exist for MNV3, as well as their strengths and limitations.

Understanding of the internal arrangement of the constituents of structural concrete, at the microscopic level, and its strength behavior, as well as its ability to result in durable concrete, are necessary in order to enhance its innovative and sustainable application. This paper presents the results of investigation conducted to ascertain the strength characteristics, microstructure configuration and durability traits of concrete with its ordinary Portland cement (OPC) fraction replaced partially with empty palm oil fruit brunch ash (EPO-FBA). The compressive strength properties were assessed with 150 x 150 x 150 cube specimens while 100 x 100 x 100 cube specimens were used to assess the durability properties. An insight into the morphology and the microstructure of samples with EPO-FBA was obtained through Scanning Electron Microscopy (SEM). The results showed that EPO-FBA is a good supplementary cementing material up to 10% replacement level, however, the samples with EPO-FBA showed a significantly improved compressive strengths development and good durability characteristics at latter ages, at the replacement level beyond 10%.

: COVID-19 is a pandemic initially identified in Wuhan, China, which is caused by a novel coronavirus, also recognized as the Severe Acute Respiratory Syndrome (SARS-nCoV-2). Unlike other coronaviruses, this novel pathogen may cause unusual contagious pain which results in viral pneumonia, serious heart problems, and even death. Researchers worldwide are continuously striving to develop a cure for this highly infective disease, yet there are no well-defined absolute treatments available at present. Several vaccination drives with emergency use authorisation vaccines are being done across many countries, however, their long term efficacy and side-effects study are yet to be done. The research community is analysing the situation by collecting the datasets from various sources. Healthcare professionals must thoroughly analyse the situation, devise preventive measures for this pandemic, and even develop possible drug combinations. Various analytical and statistical models have been developed, however, their outcome rate is prolonged. Thus, modern science stresses on the application of state-of-the-art methods in this combat against COVID-19. The application of Artificial intelligence (AI), and AI-driven tools are emerging as effective tools, especially with X-Ray and CT-Scan imaging data of infected subjects, infection trend predictions etc. The high efficacy of these AI systems can be observed in terms of highly accurate results, i.e. >95%, as reported in various studies. AI-driven tools are being used in COVID diagnostic, therapeutics, trend prediction, drug design and prevention to help fight against this pandemic. This paper aims to provide a deep insight into the comprehensive literature about AI and AI-driven tools in this battle against the COVID-19 pandemic. The extensive literature is divided into five sections, each describing the application of AI against COVID-19 viz. COVID-19 Prevention, diagnostic, infection spread trend prediction, therapeutic and drug repurposing.

The Ideal

Mathematics and Modern Science As I have pointed out elsewhere, the ideal professional equipment of the teacher of mathematics does not cease with reasonable mastery of the fundamental branches of mathematics and a wide familiarity with educational theory and practice. There is yet a third area, equally as important as these two: an adequate background of appreciation of mathematics. By this is meant some insight into the nature of mathematics, and its historical development; into the relations of mathematics to logic and philosophy; and into the broader cultural aspects of mathematics, such as its relation to pure science, to technology, to the fine arts, to the nature of thinking, and to the humanities.

Quasi Static Compression

This paper presents the effect of shape geometry on electromagnetic radiation (EMR) emissions from sintered aluminium preforms during deformation under unrestricted quasi-static compression. The EMR emissions under compression show shape anisotropy. The end surface conditions of the compressing platens, i.e. lubrication, also influence the EMR emission characteristics. The first EMR emission invariably occurs near the yield. The dead metal zones formed on the top and bottom portions of the specimens during axial compression, possibly generate a climbing motion of edge dislocations in the radially outward mid-regions. These edge dislocations form accelerated electric line dipoles and emit electromagnetic radiation during the climbing motion. These results appear significant in understanding the mechanism of plastic deformation in metal powder preforms at the microscopic level and are expected to give a deeper insight into the metal forming processes.

Insight Into

Since one of the main characteristics of the science fiction genre is the modelling of future societies, often from the safe distance perspective drawing quite visible parallels with those of the present world, the discussion about political and social topics has been an integral part of the genre since the beginnings. Moreover, since science fiction, especially regarding the subgenre of utopia, allegorically projects a particular ideology in an imaginary world, certain propaganda was also frequent compound in the genre works. These factors were largely responsible for the fact that some political regimes, especially those of the 20th century, made direct and indirect use of science fiction as a powerful tool of ideological propaganda that helped to turn the thinking of readers, especially young people, in the direction favoured by the regime. Still, it must also be remembered that the presence of political ideas in the science fiction works as well as interpretation of these works has always been quite a complicated matter, and science fiction authors frequently found ways to circumnavigate the limitations set by censorship and include messages unflattering to the regime in their works. The paper provides an insight into the aspects of relationship between science fiction and ideology in contemporary literary theory, turns a particular attention to the practical aspects of these relationships as they formed during the 20th century in the literary space of Soviet regime – discussing original works as well as translations and literary criticism; finally, the paper outlines some topical ideological directions visible in modern science fiction works.

ABSTRACT The coronavirus disease 2019 (COVID-2019) that emerged in Wuhan, China, has rapidly spread to many countries across all six WHO regions. However, its pathobiology remains incompletely understood and many efforts are underway to study it worldwide. To clarify its pathogenesis to some extent, it will inevitably require lots of COVID-2019-associated pathological autopsies. Pathologists from all over the world have raised concerns with pathological autopsy relating to COVID-2019. The issue of whether a person died from COVID-2019 infection or not is always an ambiguous problem in some cases, and ongoing epidemiology from China may shed light on it. This review retrospectively summarizes the research status of pathological autopsy for COVID-2019 deaths in China, which will be important for the cause of death, prevention, control and clinical strategies of COVID-2019. Moreover, it points out several challenges at autopsy. We believe pathological studies from China enable to correlate clinical symptoms and pathological features of COVID-2019 for doctors and provide an insight into COVID-2019 disease.

The Middle Ages

“Occult,” a 1902 international encyclopedia of religion tells us, is derived “from Latin occultus—Hidden,” and is applied to the assumption that insight into and control over nature is to be obtained by mysterious or magical procedures and by long apprenticeship in secret lore. The physical science of the middle ages, alchemy and astrology, and in modern times spiritualism, theosophy, and palmistry contain various factors of occult lore. Such doctrines, known as occultism, fall outside the realm of modern science. See MAGIC.
