Sulfuric acid is an important industrial and strategic raw material, the production of which is developing on all continents, in many factories in the world and with an annual production of over 160 million tons. On the other hand, the production, transport and usage are very dangerous and demand measures of precaution because the consequences could be catastrophic, and not only at the local level where the accident would happen. Accidents that have been publicly recorded during the last eighteen years (from 1988 till the beginning of 2006) are analyzed in this paper. It is very alarming data that, according to all the recorded accidents, over 1.6 million tons of sulfuric acid were exuded. Although water transport is the safest (only 16.38% of the total amount of accidents) in that way 98.88% of the total amount of sulfuric acid was exuded into the environment. Human factor was the common factor in all the accidents, whether there was enough control of the production process, of reservoirs or transportation tanks or the transport was done by inadequate (old) tanks, or the accidents arose from human factor (inadequate speed, lock of caution etc). The fact is that huge energy, sacrifice and courage were involved in the recovery from accidents where rescue teams and fire brigades showed great courage to prevent real environmental catastrophes and very often they lost their lives during the events. So, the phrase that sulfuric acid is a real "environmental bomb" has become clearer.

The fascinating world of lichens draws the attention of the researchers because of the numerous properties of lichens used traditionally and, in modern times, as a raw material for medicines and in the perfumery industry, for food and spices, for fodder, as dyes, and for other various purposes all over the world. However, lichens being widespread symbiotic entities between fungi and photosynthetic partners may acquire toxic features due to either the fungi, algae, or cyano-procaryotes producing toxins. By this way, several common lichens acquire toxic features. In this survey, recent data about the ecology, phytogenetics, and biology of some lichens with respect to the associated toxin-producing cyanoprokaryotes in different habitats around the world are discussed. Special attention is paid to the common toxins, called microcystin and nodularin, produced mainly by the Nostoc species. The effective application of a series of modern research methods to approach the issue of lichen toxicity as contributed by the cyanophotobiont partner is emphasized.

All over the world, a large proportion of the population consume insects as part of their diet. In Western countries, however, the consumption of insects is perceived as a negative phenomenon. The consumption of insects worldwide can be considered in two ways: on the one hand, as a source of protein in countries affected by hunger, while, on the other, as an alternative protein in highly-developed regions, in response to the need for implementing policies of sustainable development. This review focused on both the regulations concerning the production and marketing of insects in Europe and the characteristics of edible insects that are most likely to establish a presence on the European market. The paper indicates numerous advantages of the consumption of insects, not only as a valuable source of protein but also as a raw material rich in valuable fatty acids, vitamins, and mineral salts. Attention was paid to the functional properties of proteins derived from insects, and to the possibility for using them in the production of functional food. The study also addresses the hazards which undoubtedly contribute to the mistrust and lowered acceptance of European consumers and points to the potential gaps in the knowledge concerning the breeding conditions, raw material processing and health safety. This set of analyzed data allows us to look optimistically at the possibilities for the development of edible insect-based foods, particularly in Europe.

By using CoMFA and CoMSIA methods, the new quantitative structures of 25 aromatic hydrocarbons and the 96 hr-EC50 data with C. vulgaris have been investigated to obtain more detailed insight into the relationships between molecular structure and bioactivity. Compared to CoMFA (the average Q2LOO option =0.610), CoMSIA (the average Q2LOO =0.736) has the better results with robustness and stability. CoMSIA analysis using steric, electrostatic, hydrophobic, and H-bond donor and acceptor descriptors show H-bond donor is the common factor for influencing the toxicity, the steric and electrostatic descriptors are next and the hydrophobic descriptor was last. From the contour maps, the number of benzene ring is more crucial for the compound toxicity and the compounds with more benzene ring make toxicity increased. Under the same number of benzene ring, the kind of substituent group and the formed ability of H-bond are the other parameters to influencing the aromatic hydrocarbons toxicity.

Moving Parts

AbstractCurrent attempts to understand human-machine systems are complex and unwieldy. Multiple disciplines throw different concepts and constructs at the problem, but there is no agreed-to framework to assemble these interrelated moving parts into a coherent system. We propose interdependence as the common factor that unifies and explains these moving parts and undergirds the different terms people use to talk about them. In this chapter, we will describe a sound and practical theoretical framework based on interdependence that enables researchers to predict and explain experimental results in terms of interlocking relationships among well-defined operational principles. Our exposition is not intended to be exhaustive, but instead aims to describe the basic principles in a way that allows the gist to be grasped by a broad cross-disciplinary audience through simple illustrations.

People with a logical turn of mind say that the history of the world can be summarised in a sentence. A précis of mediaval historian Richard William Southern's work made in that spirit would identify two characteristics, one housed inside the other, and both quite apart from the question of its quality as a work of art. The first is his sympathy for a particular kind of medieval churchman, a kind who combined deep thought about faith with practical action. This characteristic fits inside another, touching Southern's historical vision as a whole. Its genesis is traceable to those few seconds in his teens when he ‘quarrelled’ with his father about the Renaissance. The intuition that moved him to do so became a historical fides quaerens intellectum. Reflection on Southern's life work leaves us with an example of the service an historian can perform for his contemporary world, as a truer self-perception seeps into the common consciousness by way of a lifetime of teaching and writing, spreading out through the world (all Southern's books were translated into one or more foreign language).

AbstractThis article discusses a peculiar Sā$$\dot {\text{n}}$$ n ˙ khya-Yoga theory of transformation (pariṇāma) that the author of the Pātañjalayogaśāstra created by drawing upon Sarvāstivāda Buddhist theories of temporality. In developing his theory, Patañjali adaptively reused the wording in which the Sarvāstivāda theories were formulated, the specific objections against these theories, and their refutations to win the philosophical debate about temporality against Sarvāstivāda Buddhism. Patañjali’s approach towards the Sarvāstivāda Buddhist theories was possible, even though his system of Yoga is based on an ontology that differs considerably from that of Sarvāstivāda Buddhism because both systems share the philosophical view that time is not a separate ontological entity in itself. Time is a concept deduced from change in the empirical world. This agreement results from the common philosophical orientation of Sarvāstivāda Buddhism and Yoga, which takes the phenomenon of experience as the basis of philosophical enquiry into the structure of the world. The intention that guided Patañjali’s adaptive reuse was twofold. On the one hand, he aimed at winning the debate with Sarvāstivāda Buddhism about how the problem of temporality can be solved. He thus integrated four mutually exclusive theories on temporality into a single theory of transformation of properties (dharma) involving a second-level and a third-level theory on the transformation of the temporal characteristic mark (lakṣaṇa) and on the transformation of states (avasthā), respectively. On the other hand, Patañjali intended to achieve philosophical clarification regarding the question of how exactly properties relate to their underlying substrate in the process of transformation of the three constituents or forces (guṇa) sattva, rajas and tamas of matter (pradhāna) that account for all phenomena of the world except pure consciousness (puruṣa). Patañjali’s theory of transformation is thus of central importance for his Sā$$\dot {\text{n}}$$ n ˙ khya ontology, according to which the world consists of 25 categories or constituents (tattva), i.e., of primal matter (prakṛti) and its transformations and pure consciousness.

Religious life in all eras is accompanied not only by real facts, but also by their subjective perception. It is fixed not so much reality as the imagination of it. Among the common beliefs, a special place belongs to stereotypes, which, on the one hand, systematize and generalize ideas about the world, helping people to adequately perceive and interpret being, and on the other - preserving these ideas, which sometimes prevents people from entering new life. History has given rise to many religious stereotypes, by virtue of which the constitution and preservation of ethnic groups, nations, religious communities, and confessions took place. However, uncontrolled domination, and especially the use of these stereotypes in the theory and practice of social and individual existence, led to complications in the functioning of ethno-religious communities, to their struggle, even destruction, resulting in the disappearance of some and other ethnicities, nations, religions. and churches. The reality of the society in which we live is on

Leadership is a person�s ability to convince and motivate others to do something that are related to the common goals. The leadership involved the process of convincing in determining the goal of organization, motivating the attitude of the participator to reach the goal, convincing to improve their group and culture. Leadership is a formal position, that ask to get facilities and services from the constituents that should be served. Although among the leaders that when they are inaugurated said that the position is a trust, but in fact, there is very little or it can be said almost no leader that truly implementing the leadership from their heart, that is a serving leader. Even that needs to be a note here is how a leader must have a vision in building an independent soul, views, thoughts, attitudes and behaviors of all of the people at one the leader in order to be oriented to the progress and modern, so Indonesia become a big nation and be able to have competition with the other nations in the world. A truly leader always worked hard to improve himself before the leader busy to improve the others. The leader is not only a title or position that given from the outside but something that it grows and evolves from the inside of the person.

Precipitating Factor

The majority of patients with Covid-19 have a good outcome. However, complications principally of acute respiratory distress syndrome (ARDS) and multiple-organ failure can occur rapidly. Leptospirosis, a zoonotic disease, is similar to Covid-19 in that most infections are mild or asymptomatic and only a small number develop ARDS. Cytokine storm is considered to be the main incriminating factor in both. High dose steroids have been used to ameliorate the effects in leptospirosis, and similarly, reports suggest a benefit in Covid-19. SARS CoV-2 and leptospira, one a virus and the other a bacterium, are two species separated by millions of years of evolution, but producing illnesses with similar spectra, with cytokine storm being the common precipitating factor. As data are accrued from around the world, more light may be shed on features analogous to both pathways.
