Modern materials for automotive industry

The car industry uses a tremendous number of materials to build cars, including iron, aluminum, steel, glass, rubber, petroleum products, copper, steel and others. These materials have evolved greatly over the decades, becoming more sophisticated, better built, and safer. They've changed as new automotive manufacturing technologies have emerged over the years, and they're used in increasingly innovative ways. This article is devoted to systematization information on the introduction and application of modern materials in the automotive industry. Given both domestic and foreign sources of information, it follows that car manufacturers are constantly pushing to create the lightest cars possible to increase speed and power. Research and development into lightweight materials is essential for lowering their cost, increasing their ability to be recycled, enabling their integration into vehicles, and maximizing their fuel economy benefits. Light weighting without loss of strength and speed properties is the present, and the future, of the automotive manufacturing industry. It brings innovative materials to the frontline of design

The Accidental Terrorist: Okhrana Connections to the Extreme-Right and the Attempt to Assassinate Sergei Witte in 1907

This article represents a case study in the relationship between the tsarist secret police (commonly known as the Okhrana in the West and okhranka in Russia) and acts of political terror perpetrated by the extreme-right in late imperial Russia. This specific case concerns the tangled web of conspiracy, propaganda and controversy that surrounded the attempted assassination of former-Chairman of the Council of Ministers, Sergei Witte, in 1907

Цереброваскулярная болезнь: фармакологические свойства и эффективность дипиридамола как препарата с плейотропным механизмом действия

Main clinical-pharmacological effects of dipiridamol action are considered in the context of its use in case of cerebrovascular disease. The vasodilatating effect of the medicine, antioxidative effect and ability to improve tissue perfusion are accentuated. The results of experimental and clinical research work reflecting efficacy and safety of dipiridamol are introduced. Pleiotropic action mechanism of the medicament whicht makes it possible to have a complex influence at pathogenetic factors of cerebrovascular disease is noted.Рассмотрены основные клинико-фармакологические эффекты дипиридамола в контексте его применения при цереброваскулярной болезни. Сделан акцент на вазодилатирующем действии препарата, его способности улучшать перфузию тканей и антиоксидантном эффекте. Приведены результаты экспериментальных и клинических исследований, отражающих эффективность и безопасность дипиридамола. Отмечен плейотропный механизм действия препарата, позволяющий достичь комплексного воздействия на патогенетические факторы цереброваскулярной болезни

New and interesting records of phytophagous arthropods in green spaces of Donbass. Report IX

<p>The paper contains data about 18 species of aphids (Insecta: Hemiptera: Aphididae) registered in the green spaces of Donbass in 2007, 2018–2022. All species are registered for the first time for the fauna of Donbass. For the first time for the European part of Russia Patchiella reaumuri (Kaltenbach, 1843) was recorded, and its development on Tilia cordata L. was recorded for the first time too. Of the non-migratory species, 6 are monophagous, 4 are oligophagous. Dangerous pests of horticultural crops include Pterochloroides persicae (Cholodkovsky, 1899) and Brachycaudus cardui cardui (Linnaeus, 1758), ornamental plants – Hyadaphis passerinii (DelGuercio, 1911). Acyrthosiphon lactucae (Passerini, 1860), Anoecia corni (Fabricius, 1775), Aphis nasturtii Kaltenbach, 1843, and B. cardui cardui can be vectors of dangerous plant viral diseases.</p&gt

Principles of Bragg-Fresnel multilayer optics

The paper describes the principles and theoretical models of new X-ray optical elements based on the behaviour of Bragg-Fresnel diffraction. The use of volume diffraction permits one to achieve better spatial resolution compared with conventional plane optics and bending mirrors. The construction of Bragg-Fresnel elements combines the advantages of high-resolution Fresnel optics with stability of multilayer mirrors.Cet article décrit les principes et les modèles théoriques de nouveaux éléments optiques utilisant à la fois la diffraction de Bragg et celle de Fresnel. La diffraction de Bragg sur les plans successifs d'une multicouche permet d'obtenir une meilleure résolution spatiale que celle des optiques à miroirs conventionnels plans ou courbes. Les optiques de Bragg-Fresnel combinent les avantages de la bonne résolution spectrale des optiques à réseaux de type Fresnel avec la stabilité des miroirs multicouches
