Nietzsche and Psychedelics – Peter Sjöstedt-H –
Antichrist Psychonaut: Nietzsche and Psychedelics – Peter Sjöstedt-H – ‘… And close your eyes with holy dread, For he on honey-dew hath fed, And drunk the milk of Paradise.’ So ends the famous fragment of Kubla Khan by the Romantic poet, Samuel Taylor Coleridge. He tells us that the poem was an immediate transcription of an opium-induced dream he experienced in 1797. As is known, the Romantic poets and their kin were inspired by the use of psychoactive substances such as opium, the old world’s common pain reliever. Pain elimination is its negative advantage, but its positive attribute lies in the psychedelic (‘mind- revealing’)1 state it can engender – a state described no better than by the original English opium eater himself, Thomas De Quincey: O just and righteous opium! … thou bildest upon the bosom of darkness, out of the fantastic imagery of the brain, cities and temples, beyond the art of Phidias and Praxiteles – beyond the splendours of Babylon and Hekatómpylos; and, “from the anarchy of dreaming sleep,” callest into sunny light the faces of long-buried beauties … thou hast the keys of Paradise, O just, subtle, and mighty opium!2 Two decades following the publication of these words the First Opium War commences (1839) in which China is martially punished for trying to hinder the British trade of opium to the Chinese people. Though opium, derived from the innocent garden poppy Papavar somniferum, may cradle the keys to Paradise it also clutches the keys to Perdition: its addictive thus potentially ruinous nature is commonly known. Today, partly for these reasons, opiates are mostly illegal without license – stringently so in their most potent forms of morphine and heroin. -

Canine Status Epilepticus Care
Vet Times The website for the veterinary profession https://www.vettimes.co.uk CANINE STATUS EPILEPTICUS CARE Author : Stefano Cortellini, Luisa de Risio Categories : Vets Date : August 2, 2010 Stefano Cortellini and Luisa de Risio discuss emergency management techniques for a condition that can claim the lives of 25 per cent of afflicted dogs – as the quicker the start of treatment, the better the chances of control STATUS epilepticus (SE) is a neurological emergency with a mortality of up to 25 per cent in dogs (Bateman, 1999). SE can be defined as continuous epileptic seizure (ES) activity lasting longer than five minutes, or as two or more ES with incomplete recovery of consciousness interictally. SE has also been defined as continuous seizure activity lasting for 30 minutes or longer. However, emergency treatment to stop the ES should be administered well before the defined 30-minute time. The most common type of SE is generalised tonic-clonic status. When this is prolonged, the tonic- clonic clinical manifestations can become subtle, with only small muscle twitching and altered mentation. This status is called electromechanical dissociation, as continued abnormal electrical activity in the brain persists while the motor manifestations are minimal to absent. In these cases, emergency anti-epileptic treatment is necessary as for tonic-clonic status. SE can be divided into two stages. The first stage is characterised by generalised tonicclonic seizures and an increase in autonomic activity that causes tachycardia, hypertension, 1 / 7 hyperglycaemia, hyperthermia and increased cerebral blood flow. The second stage of SE starts after about 30 minutes and is characterised by hypotension, hypoglycaemia, hyperthermia, hypoxia, decreased cerebral blood flow, cerebral oedema and increased intracranial pressure. -

Dr Norman Sartorius, Director, Division of Mental Health WHO, discussed with the ipants the conditions in the developing nations which must be considered in reaching regarding the recommendation of substances for international control. He referred ifically to a gradual change in the attitude of people towards pain. No longer is pain as a natural accompaniment of disease.

Global Lithium Sources—Industrial Use and Future in the Electric Vehicle Industry: a Review
resources Review Global Lithium Sources—Industrial Use and Future in the Electric Vehicle Industry: A Review Laurence Kavanagh * , Jerome Keohane, Guiomar Garcia Cabellos, Andrew Lloyd and John Cleary EnviroCORE, Department of Science and Health, Institute of Technology Carlow, Kilkenny, Road, Co., R93-V960 Carlow, Ireland; [email protected] (J.K.); [email protected] (G.G.C.); [email protected] (A.L.); [email protected] (J.C.) * Correspondence: [email protected] Received: 28 July 2018; Accepted: 11 September 2018; Published: 17 September 2018 Abstract: Lithium is a key component in green energy storage technologies and is rapidly becoming a metal of crucial importance to the European Union. The different industrial uses of lithium are discussed in this review along with a compilation of the locations of the main geological sources of lithium. An emphasis is placed on lithium’s use in lithium ion batteries and their use in the electric vehicle industry. The electric vehicle market is driving new demand for lithium resources. The expected scale-up in this sector will put pressure on current lithium supplies. The European Union has a burgeoning demand for lithium and is the second largest consumer of lithium resources. Currently, only 1–2% of worldwide lithium is produced in the European Union (Portugal). There are several lithium mineralisations scattered across Europe, the majority of which are currently undergoing mining feasibility studies. The increasing cost of lithium is driving a new global mining boom and should see many of Europe’s mineralisation’s becoming economic. The information given in this paper is a source of contextual information that can be used to support the European Union’s drive towards a low carbon economy and to develop the field of research. -

Eng., 21(5), 1010-1014 (2004) Physical and Electrochemical Properties of 1-Butyl-3-methylimidazolium Bromide, 1-Butyl-3-methylimidazolium Iodide, and 1-Butyl-3-methylimidazolium Tetrafluoroborate Ki-Sub Kim, Bae-Kun Shin and Huen Lee† Department of Chemical and Biomolecular Engineering, Korea Advanced Institute of Science and Technology, 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Republic of Korea (Received 12 December 2003 • accepted 10 May 2004) Abstract−The density, viscosity, refractive index, heat capacity, heat of dilution, ionic conductivity, and electrochemi- cal stability of 1-butyl-3-methylimidazolium bromide ([bmim][Br]), 1-butyl-3-methylimidazolium iodide ([bmim][I]), and 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF4]) were measured at room temperature or over a tem- perature range of 293.2 to 323.2 K. The density and refractive index values of [bmim][I] appeared to be the highest among three ionic liquids (ILs). However, the experimental viscosity values of [bmim][Br] were higher than those of [bmim][BF4], while the heat capacities and heats of dilution of [bmim][BF4] were higher than those of [bmim][Br]. The cyclic voltammogram of [bmim][br] and [bmim][BF4] indicated electrochemical windows in the stability range from 2.7 V of [bmim][[Br] to 4.7 V of [bmim][BF4]. Key words: Physical Property, Electrochemical Property, 1-Butyl-3-methylimidazolium Bromide, 1-Butyl-3-methylimidazo- lium Tetrafluoroborate, and 1-Butyl-3-methylimidazolium Iodide INTRODUCTION The 1-methylimidazole (99%), 1-chlorobutane (99.5%), 1-bro- mobutane (99%), 1-iodobutan(99%), 1,1,1-trichloroethane (99.5%), Ionic Liquids (ILs) are generally salts based on a substituted het- ethylacetate, and sodium tetrafluoroborate (98%) were supplied by − − erocyclic cation and an inorganic anion such as [AlCl4] , [BF4] , or Aldrich.
