Joseph Sidebotham (1824–1885) was a Manchester cotton baron whose natural history collections are now in the Manchester Museum. In addition to collecting he suggested a method for identifying and classifying Lepidoptera and investigated variation within species as well as species limits. With three close collaborators, he is credited with discovering many species new to Britain in both Lepidoptera and Coleoptera. A suspicion of fraud attaches to these claims. The evidence is not clear-cut in the Lepidoptera, but a possible reason is suggested why Sidebotham, as an amateur in the increasingly professional scientific world, might have engaged in deceit.

European Renaissance

The present paper attempts to expose how the scientific world-view of nature contributes to the present environmental crisis. Alongside this, it relates European Renaissance, humanism, secularism, the scientific and industrial revolutions, modern philosophy, scientism, technology-based modern life, consumerism-based modern society, etc. with current environmental problems. By focusing on Nasr’s traditional understanding of nature, the paper explores how materialistic and mechanistic world-views are deeply connected with the present ecological crisis. It also offers a critical analysis of Nasr’s spiritual and religious world-view of nature and examines its relevance. In doing so, it aims to highlight some demerits of the present world-view, and to call to reform current perceptions of nature by revitalizing traditional wisdom in order to protect the environment from further degradation. Thus, the paper is scholarly addition to the ongoing discourse on the issue of religions and the environment. Keywords: Eco-theology, Environmental Degradation, Materialistic and Mechanistic Views of Nature, Scientism, Spiritual Crisis of Modern humans, Religious and Spiritual World-Views.   Abstrak Kertas kajian ini menerangkan bagaimana pandangan saintifik telah menyumbang kepada krisis alam sekitar semasa. Disamping itu, kertas ini akan menhubungkaitkan Gerakan Revolusi Humanisma di Eropah, sekularisme, revolusi  sains dan perindustrian, falsafah moden, saintisme, kehidupan moden yang berasaskan teknologi, masyarakat moden yang berasaskan consumerisme, etc. dengan krisis alam sekitar yang berlaku dewasa ini.  Dengan memahami pandangan Nasr terhadap alam sekitar, kertas ini akan merungkai bagaimana pandangan materialistik (kebendaan) dan mekanistik mempengaruhi krisis ekologi masa kini. Ia juga akan menganalisa pandangan spiritual dan agama Nasr terhadap alam sekitar secara kritikal dan akan menilai sejauh mana kesesuaiannya. Dengan sedemikian dapat menyedarkan manusia tentang kecacatan pandangan semasa, yang kemudiannya akan membawa kepada pembaharuan persepsi mereka terhadap alam sekitar dengan cara menghidupkan semula nilai-nilai tradisional demi mengelakkan kemerosotan alam sekitar.

Background: Data which are in the form of text, audio, image and video are used everywhere in our modern scientific world. These data are stored in physical storage, cloud storage and other storage devices. Some of it are very sensitive and requires efficient security while storing as well as in transmitting from the sender to the receiver. Objective: With the increase in data transfer operation, enough space is also required to store these data. Many researchers have been working to develop different encryption schemes, yet there exist many limitations in their works. There is always a need for encryption schemes with smaller cipher data, faster execution time and low computation cost. Methods: A text encryption based on Huffman coding and ElGamal cryptosystem is proposed. Initially, the text data is converted to its corresponding binary bits using Huffman coding. Next, the binary bits are grouped and again converted into large integer values which will be used as the input for the ElGamal cryptosystem. Results: Encryption and Decryption are successfully performed where the data size is reduced using Huffman coding and advance security with the smaller key size is provided by the ElGamal cryptosystem. Conclusion: Simulation results and performance analysis specifies that our encryption algorithm is better than the existing algorithms under consideration.

A New Technique

AbstractThis study has been inspired by golf ball movements during the game to improve particle swarm optimization. Because, all movements from the first to the last move of the golf ball are the moves made by the player to win the game. Winning this game is also a result of successful implementation of the desired moves. Therefore, the movements of the golf ball are also an optimization, and this has a meaning in the scientific world. In this sense, the movements of the particles in the PSO algorithm have been associated with the movements of the golf ball in the game. Thus, the velocities of the particles have converted to parabolically descending structure as they approach the target. Based on this feature, this meta-heuristic technique is called RDV (random descending velocity) IW PSO. In this way, the result obtained is improved thousands of times with very small movements. For the application of the proposed new technique, the inverse kinematics calculation of the 7-joint robot arm has been performed and the obtained results have been compared with the traditional PSO, some IW techniques, artificial bee colony, firefly algorithm and quantum PSO.

Dentistry, as a branch of medicine, has undergone continuous evolution over time. The scientific world has focused its attention on the development of new methods and materials with improved properties that meet the needs of patients. For this purpose, the replacement of so-called “passive” dental materials that do not interact with the oral environment with “smart/intelligent” materials that have the capability to change their shape, color, or size in response to an externally stimulus, such as the temperature, pH, light, moisture, stress, electric or magnetic fields, and chemical compounds, has received much attention in recent years. A strong trend in dental applications is to apply nanotechnology and smart nanomaterials such as nanoclays, nanofibers, nanocomposites, nanobubbles, nanocapsules, solid-lipid nanoparticles, nanospheres, metallic nanoparticles, nanotubes, and nanocrystals. Among the nanomaterials, the smart nanoparticles present several advantages compared to other materials, creating the possibility to use them in various dental applications, including preventive dentistry, endodontics, restoration, and periodontal diseases. This review is focused on the recent developments and dental applications (drug delivery systems and restoration materials) of smart nanoparticles.

The names that have just been recounted include those of many outstanding personalities in the scientific world and it would not be fitting to attempt even brief appreciations of their manifold services on this occasion. An exception must, however, be made when we mourn such giants as two of the deceased Fellows. Sir Frederick Gowland Hopkins, O. M., was elected a Fellow of the Society in 1905; he delivered the Croonian Lecture in 1915, was Royal Medallist in 1918 and Copley Medallist in 1926. He was President of the Society from 1930 to 1935. Such are the bare facts, and though we are proud of his intimate association with the Royal Society, we do not now think of a Lecturer, a Medallist, or even of a President. Our memory dwells rather on the lovable qualities and magnanimous spirit of a devoted teacher and leader, and on the influence of his generous help to others as well as of his personal achievements during almost seventy years of scientific life. He was early imbued with the conviction that the chemistry of the living cell was his subject, that it was not only of transcendent importance, but also that it was ripe for development. He dedicated himself to the quest and embarked with enthusiasm on a pioneering voyage of discovery. The outcome of his courage and industry was the foundation of a new scientific discipline, if not of a new science. He was the father of modern schools of biochemistry and was the greatest biochemist of his generation.

Abstract This is an essay on the origin of theories. It argues that methodology can do more than shape scientific theories—sometimes, vocabularies of method become such theories. The origin of Charles Darwin’s theory of evolution by natural selection is a case in point: Darwin’s well-known attention to methodological matters not only framed but bled into his theory of nature. A careful student of contemporary methodology, Darwin sought guidance for using a controversial tool in the scientific world in which he came of age: the hypothesis. In the process of reading the works of John Herschel and William Whewell, Darwin turned nature itself into a man of science. The hypotheses and testing of scientific practice were mirrored in the variations and selection of the natural world. Though unintentional, Darwin’s naturalization of a vocabulary of method helped pave the way for applications of evolutionary theory to the study of the human mind and, completing the circle, to the philosophy of science. Considering the role of vocabularies of method in the origin of theories suggests new directions for the study of cognitive history and the power of language to transform the historical imagination.

This is not the first time that great universities have had to shut their doors during an epidemic. And there is perhaps a lesson for all students about what can happen during a shutdown. In 1665, Cambridge University closed as the bubonic plague swept across England. Isaac Newton, a 22-year-old student, was forced to retreat to the family farm, Woolsthorpe Manor. Isolated there for more than a year, on his own he revolutionized the scientific world. Newton said that this shutdown freed him from the pressures of the curriculum and led to the best intellectual years of his life.

A review article is based on current foreign sources. The level of cytokines in the peripheral blood can be increased in many diseases, but in some cases there may be an excess of their normal concentration in tens, hundreds or more times with the development of a peculiar clinical picture, which is based on a systemic inflammatory reaction. In the literature this condition has received the figurative name «cytokine storm», which highlights an extremely violent reaction of the immune system with an unknown (often unfavorable) outcome. Close attention of the scientific world and the public to the problem of extremely high levels of cytokines in the peripheral blood (hypercytokinemia) was drawn due to the high frequency of the cytokine storm in the novel coronavirus infection.
