Microscopic world

Ebook "From the molecular World: A nineteenth-century science fantasy" provided an examination of the chemistry and physics of his day that was always light-hearted on the surface, but often surprisingly profound. Properly interpreted, the book provides a revealing tour of nineteenth-century debates concerning chemical theory. It is here translated into English, richly annotated, and equipped with an illuminating preface by a leading historian of chemistry. It provides entertaining reading to practicing chemists, as well as new insights to historians of science.

The 4th industrial revolution is paved by scientific breakthroughs into the microscopic world and the discovery of new world laws, including 3D printing technology. 3D printing is a "additive manufacturing" technology. This technology works in reverse of “subtraction manufacturing”, gradually removing excess material from the original workpiece in order to finally obtain the desired product.

Harmful cyanobacterial blooms (HCB) have become a global threat to human health and aquatic biota around the world. While the ecotoxicity of microcystins (MC) producing cyanobacteria such as Microcystis spp. has been studied extensively, little is known about toxic effects of others filamentus cyanobacteria such as Anabaena spp. In this study, several strains of Anabaena sp. were isolated from Tri An Reservoir and cultured under laboratory conditions. Microscopic observation was used for morphological identification.

Powdery mildew caused by Golovinomyces cichoracearum (DC.) V.P. Heluta (formerly Erysiphe cichoracearum) is a common foliar disease on senescing leaves of cultivated sunflower in warmer regions of the world. In India, the powdery mildew disease is becoming major constraint in cultivation of sunflower crop especially during post rainy season. Screening of the sunflower germplasm lines against the disease would be of a great help to identify the resistance source.

Chilli is one of the important spices and cultivated around the world for its peculiar hot taste. Chilli leafs prone to affect by Alternaria alternata (leaf spot). In order to overcome this problem, efforts have been made to evaluate the efficiency of the bio-control agent Trichoderma harzianum for controlling the leaf spot disease in chilli. Trichoderma harzianum was isolated from the field soil and identified through microscopic and recommended standard methods.

The research on hydrophobic and superhydrophobic surface has been extensively studied by many groups around the world. The parameter determined the wetting ability of a surface is value of water contact angle. Measuring contact angle become extremely important for both academic and industrial field. In this study, we propose a simple and affordable methodology to calculate contact angle. This approach used portable microscope of Koolertron for droplet images capturing and free software of ImageJ for contact angle fitting and calculation.

Harmful cyanobacterial blooms have become a global threat to human health and aquatic biota around the world. While the ecotoxicity of cyanobacterial toxins such as microcystins (MCs) has been studied extensively, the toxicity of non-toxin producing cyanobacteria has not been evaluated to the same extent. In this study, five strains of Microcystis wesenbergii were isolated from the Tri An reservoir and cultured under laboratory conditions. Microscopic observation was used for morphological identification. The MCs concentration was measured by highperformance liquid chromatography (HPLC).

Superficial mycoses are the most frequent forms of human infections, Dermatophytes affecting more than 20 to 25% of the world’s population. They are predominantly caused by the keratinophilic fungi in the genera of Trichophyton, Microsporum and Epidermophyton. 1. Isolation and identification of Dermatophytes causing skin, hair and nail infections. 2. To know the prevalence of Dermatophytic infections in Tertiary care hospital. This study was conducted from April 2018 to July 2018 in Department of Microbiology, J. J. M. Medical College, Davanagere.

India is recognized as a significant producer of orchids in the world. Nearly 1300 species of orchids are found in India which constitutes almost 10 percent of the world orchid flora with Himalayas as their main home (Medhi and Chakrabati, 2009). Orchids are amongst the most advanced flowering plants, highly specialized in many ways. They are distributed all over the world except the Antarctica (Ali and Mir, 2013).

In recent years, three-dimensional (3D) in vitro tumor models have become more common in cancer research across the world. Selecting scaffolds, seeding cells into the scaffolds, and culturing them are pivotal for the morphologies and proliferation of cancer cell lines. Therefore, this experience has developed a 3D tumor model based on co-culturing MCF-7 cells and fibroblasts (3:1) into gelatin-alginate scaffolds (3x3x5 mm3 ).

This is a new and fully revised edition of Jeffrey and Leach: Atlas of Medical Helminthology and Protozoology . Helminths (worms) and similar parasites are a major medical problem in much of the world and perhaps the largest single cause of morbidity and mortality (eg malaria, elephantiasis, trypanosmiasis). The diagnosis of these conditions still largely rests on the microscopic examination of, for example, faeces. This atlas illustrates the different myriad of different organisms and how to identify them. The atlas covers all helminths and protozoa of medical importance.

No one would have believed in the last years of the nineteenth century that this world was being watched keenly and closely by intelligences greater than man’s and yet as mortal as his own; that as men busied themselves about their various concerns they were scrutinised and studied, perhaps almost as narrowly as a man with a microscope might scrutinise the transient creatures that swarm and multiply in a drop of water. With infinite complacency men went to and fro over this globe about their little affairs, serene in their assurance of their empire over matter.

In 1665, a book was published that inaugurated the use of the microscope to investigate the natural world. The author was Robert Hooke, a talented artist, architect, and amateur scientist. Hooke wrote Micrographia: Or Some Physiological Descriptions of Minute Bodies Made by Magnifying Glasses with Observations and Inquiries Thereupon, at the behest of the newly chartered Royal Society in London, for whom he was working as curator of scientific experiments. In Micrographia, he presented the first detailed observations of everyday objects made with his self-constructed light microscope....

Perhaps quantum mechanics is viewed as the most remarkable development in 20th century physics. Each successful theory is exclusively concerned about "results of measurement". Quantum mechanics point of view is completely different from classical physics in measurement, because in microscopic world of quantum mechanics, a direct measurement as classical form is impossible. Therefore, over the years of developments of quantum mechanics, always challenging part of quantum mechanics lies in measurements.
