Livsmedelsvetenskap är ett tvärvetenskapligt ämne som belyser mat ur olika vetenskapliga perspektiv. Det omfattar livsmedelskedjan, från råvarans ursprung och kemiska sammansättning till förädling, tillagning och konsumtion. Vårt livsmedelssystem står inför en nödvändig omställning. För att möta framtidens utmaningar måste vi främja hälsa, klimat och miljö. Dessutom måste systemet kunna försörja befolkningen med tillräcklig mat och näring även under kriser.Livsmedelsvetenskap ger svar på aktuella frågor som rör hela kedjan från odling och uppfödning till den ätfärdiga maträtten med målet att sträva mot en hälsosammare och mer hållbar livsmedelsproduktion och konsumtion. I denna utgåva har de uppdaterade Nordiska näringsrekommendationerna och ett kapitel om växtbaserade livsmedel inkluderats.Denna bok inleds med övergripande kapitel om livsmedelskvalitet, konserveringsmetoder och matlagningstekniker. Därefter följer kapitel om respektive livsmedelsgrupp från råvarans ursprung, via kemisk sammansättning, till vad som händer under tillagning. Närings-, hälso- och miljöaspekter behandlas på respektive råvara.Genomgående innehåller kapitlen fakta om:• råvarans ursprung, uppbyggnad och sammansättning• kvalitetskriterier• industriell tillverkning• förvaring, beredning och tillagningsmetoder• miljö och hälsa.Boken vänder sig i första hand till studenter på högskola/universitetet samt även andra matintresserade personer. Boken är tänkt att användas på utbildningar inom livsmedelsvetenskap för dietister, gastronomer, kostekonomer, kostvetare, lärare i hem- och konsumentkunskap, livsmedelsagronomer och nutritionister.

The ultimate eye-opening journey through time and space, A Short History of Nearly Everything is the biggest-selling popular science book of the 21st century and has sold over 2 million copies.'Possibly the best scientific primer ever published.' Economist'Truly impressive...It's hard to imagine a better rough guide to science.' Guardian'A travelogue of science, with a witty, engaging, and well-informed guide' The TimesBill Bryson describes himself as a reluctant traveller, but even when he stays safely at home he can't contain his curiosity about the world around him. A Short History of Nearly Everything is his quest to understand everything that has happened from the Big Bang to the rise of civilization - how we got from there, being nothing at all, to here, being us.Bill Bryson's challenge is to take subjects that normally bore the pants off most of us, like geology, chemistry and particle physics, and see if there isn't some way to render them comprehensible to people who have never thought they could be interested in science. As a result, A Short History of Nearly Everything reveals the world in a way most of us have never seen it before.

De tekniska och medicinska framgångarna som vi har idag kommer från vår förståelse om materiens partikelnatur. Att förstå vad en atom är och hur den samverkar med sin omgivning är en förutsättning för att kunna vidareutveckla tekniken vi använder idag. Denna kunskap är även viktig för att vi ska kunna förstå hur ämnen sprids i vår omgivning och hur de påverkar vår miljö och hälsa. Trots att vi har känt till materiens partikelnatur i över hundra år är det vanligt att många förklarar naturvetenskapliga fenomen på ett sätt som man gjorde innan atomen var upptäckt. Dessa ålderdomliga förklaringar kan försvåra en individs lärande om naturvetenskapliga fenomen. Genom att tidigt introducera materiens partikelnatur för elever i grundskolans lägre åldrar kan man på så sätt ge dem en grundläggande förståelse för de naturvetenskapliga fenomenen, vilket är viktigt för deras framtida skolgång och livslånga lärande. En förutsättning för att kunna genomföra detta för elever i f-6 är att där finns pedagoger som förstår materiens uppbyggnad. Boken går igenom några viktiga begrepp och fenomen som är kopplade till material och ämnens uppbyggnader, deras egenskaper och omvandlingar, samt barns tankar om dessa begrepp. Boken innehåller även förslag på övningar som är anpassade för elever från förskoleklass upp till år 6 och för pedagoger som ska undervisa eleverna om dessa begrepp. Boken riktar sig i första hand till blivande och verksamma grundlärare f-6.

Prepare to be dazzled by this contemporary guide to the art of crystalline glazing.Crystalline glazes are known for producing exciting works reminiscent of floating galaxies, frosty windows, rare gemstones and delicate flowers. Until recently, however, few potters worked with this elusive medium. Now, with new advancements in materials and digital processors, the method has become simplified and amazing results can be achieved without the problems usually associated with these glazes, such as excessive glaze run-off and unpredictable crystal growth. In this book, Diane Creber explores the history of this process, beginning with the most suitable clays, the different types of crystalline glazes, how they can be grown under controlled conditions, and how different ingredients react with each other. Through a survey of several well-known crystalline glaze potters, she reveals their secrets and shows examples of their unique work. From clay and glaze recipes to an in-depth look at firing aids and types of kilns, Exploring Crystalline Glazes has everything a potter needs to make their own glazes and create their own stunning works of art.

Megaliter & andra stenar är en publikation om sten. Vad sten är, vad sten gör, vad sten gör med oss och vi med den, på vilka sätt vi är sammanbundna och ändå obevekligt separerade. Dessa och en lång rad andra steniga frågor närmar sig Megaliter & andra stenar genom en mängd historiska och mer samtida bilder och texter: poetiska, filosofiska, teoretiska, dokumenterande, spekulativa, historiserande – eller en kombination av eller rörelse mellan flera av dessa praktiker. Vi dröjer både vid megalitstrukturer i form av stenrader, stencirklar och gånggrifter, som vid enskilda stenar: allt från ”London Stone” och ”Stone of Scone” till diabaspelaren ”Ramle” på Nordbillingen; den mytomspunna inskriberade ”Stenen i Grönan dal” i Jämtland; stenformationen ”Áhkánjárstábba” vid Kvalsundet; den skålgropsbemängda ”Ballersten” i Falköpings stadspark; Stockholms enda naturminne i form av en sten: ”Biskopsmössan” i Huddinge… Megaliter & andra stenar närmar sig sten genom forskning och folklore: genom teoretiska texter av Manuel De Landa, Ingrid Hoelz & Rémi Marie, Thomas E. Balke, Sascha A. Schultz; genom utdrag ur Johan Götlinds Saga, sägen och folkliv i Västergötland från 1926, lika väl som ur Nils Henrik Sjöborgs Samlingar för Nordens Fornälskare, Innehållande Inskrifter, Figurer, Ruiner, Verktyg, Högar och Stensättningar i Sverige och Norrige från 1820-talet och Johan Göranssons Bautil, Det är: Alle Svea ok Götha Rikens BAUTASTENAR från 1750. Grundstenarna i publikationen är dock de tre block om megalitkultur i Carnac i Frankrike, Avebury i England och på Ekornavallen och Falbygden i Sverige, som Magnusson & Grönberg har arbetat fram över lång tid, och som bygger på skilda och samtidigt överlagrade fältarbeten i topografier och arkiv, i text och bild. I publikationen ryms både en stor mängd historiska bilder från 1700-talet och framåt och fotografiska serier från de senaste åren.

Boken beskriver och förklarar organiska molekylers otroliga mångfald, deras strukturer och egenskaper, och hur de kan delta i kemiska reaktioner och därmed användas i samhället. Den organiska kemin är fundamental för många vetenskapliga områden, den lägger till exempel grunden för livsprocesserna, och kunskaper i ämnet öppnar många dörrar.I denna tredje upplaga av boken har materialet till stor del om arbetats. Dels delas materialet tydligare in i en deskriptiv del som beskriver fysikalisk-organiska begrepp och olika föreningsklasser, och en mer mekanistisk del som beskriver organiska föreningars reaktioner och hur man kan utnyttja dem. Mellan de två blocken ges en introduktion till modeller för elektronfördelning och till slut ytterligare två deskriptiva kapitel om organisk analys och biologiska makromolekyler. Ett helt nyskrivet kapitel beskriver den metall organiska kemin som har utvecklats snabbt under de senaste åren, och den tredje upplagan har även utökats med ett avsnitt om grön kemi. Boken avslutas som tidigare med en grafisk sammanfattning och en epilog.Läroboken riktar sig i första hand till studerande på högskola/universitet som har för avsikt att tillägna sig grundläggande kunskaper i organisk kemi, samt till den som vill fräscha upp gamla kunskaper i

Crystals have fascinated us for centuries with their beauty and symmetry, and have often been invested with magical powers. The use of X-ray diffraction, first pioneered in 1912 by father and son William and Lawrence Bragg, enabled us to probe the structure of molecules, and heralded the scientific study of crystals, leading to an understanding of their atomic arrangements at a fundamental level. The new discipline, called X-ray crystallography, has subsequently evolved into a formidable science that underpins many other scientific areas. Starting from the determination of the structures of very simple crystals, such as that of common salt, today it has become almost routine to determine the positions of tens of thousands of atoms in a crystal. In this Very Short Introduction Mike Glazer shows how the discoveries in crystallography have been applied to the creation of new and important materials, to drugs and pharmaceuticals and to our understanding of genetics, cell biology, proteins, and viruses. Tracing the history of crystallography, he analyses astonishing developments in new sources of X-rays, as well as of neutrons, and in electron microscopy, and considers the impact they have on the study of crystals today. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Författaren till boken Organisk-kemisk nomenklatur - En introduktion till det kemiska språket vänder sig i sin framställning främst till alla studerande och yrkesverksamma som behöver en handbok i grundläggande organisk-kemisk nomenklatur. Det genomgående temat i boken är IUPAC:s substitutiva nomenklatur, men även mer speciella områden, t.ex. ringsystem och isotopiskt modifierade föreningar, behandlas. Organisk-kemisk nomenklatur är främst avsedd som vägledning vid översättning av kemiska namn till strukturformler, men behandlar också några typexempel på namnkonstruktion. Många exempel på ringnomenklatur har hämtats från läkemedelsområdet, och behandlingen av aminosyrenomenklatur är mer utförlig än tidigare. Uno Svensson var fram till sin pensionering år 2011 universitetslektor i organisk kemi vid Farmaceutiska Fakulteten, Uppsala Universitet.

By tackling the most central ideas in chemistry, Why Chemical Reactions Happen provides the reader with all the tools and concepts needed to think like a chemist. The text takes a unified approach to the subject, aiming to help the reader develop a real overview of chemical processes, by avoiding the traditional divisions of physical, inorganic and organic chemistry. To understand how chemical reactions happen we need to know about the bonding in molecules, how molecules interact, what determines whether an interaction is favourable or not, and what the outcome will be. Answering these questions requires an understanding of topics from quantum mechanics, through thermodynamics, to "curly arrows". In this book all of these topics are presented in a coherent and coordinated fashion, showing how each leads to a deeper understanding of chemical reactions.

In The Secrets of Alchemy, Lawrence M. Principe, one of the world's leading authorities on the subject, brings alchemy out of the shadows and restores it to its important place in human history and culture. By surveying what alchemy was and how it began, developed, and overlapped with a range of ideas and pursuits, Principe illuminates the practice. He vividly depicts the place of alchemy during its heyday in early modern Europe, and then explores how alchemy has fit into wider views of the cosmos and humanity, touching on its enduring place in literature, fine art, theater, and religion as well as its recent acceptance as a serious subject of study for historians of science. In addition, he introduces the reader to some of the most fascinating alchemists, such as Zosimos and Basil Valentine, whose lives dot alchemy's long reign from the third century down to the present day.Through his exploration of alchemists and their times, Principe pieces together closely guarded clues from obscure and fragmented texts to reveal alchemy's secrets, and - most exciting for budding alchemists - uses them to recreate many of the most famous recipes in his lab, including those for the "glass of antimony" and "philosophers' tree." This unique approach brings the reader closer to the actual work of alchemy than any other book.

Kepler's essay, On the Six-Cornered Snowflake, provides the first published evidence of the ideas of regular arrangements and close-packing which have proved fundamental to crystallography. In it, Kepler ponders on the problem of why snowflakes are hexagonal, two centuries before the first successful steps were taken towards its solution. The purpose of this volume is to display the historical, literary, scientific, and philosophical treasures of Kepler's essay. The book includes the modernized text of the 1611 Latin edition, with an English translation by Colin Hardie on the opposite pages. The text is accompanied by an introduction giving details of the history of the work, and two essays; Professor B. J. Mason's discussion of the scientific meaning and validity of Kepler's arguments and their relation to the history of crystallography and of space filling, and L. L. Whyte's examination of Kepler's facultas formatrix in relation to the history of philosophical and scientific ideas on the genesis of forms.

With Reactions bestselling author Theodore Gray continues the journey through our molecular and chemical world that began with the tour de force The Elements and continued with Molecules. In The Elements, Gray gave us a never-before-seen, mesmerizing photographic view of the 118 elements in the periodic table. In Molecules, with the same phenomenal photographic acumen, plus beautifully rendered computer generated graphics, he showed us how the elements combine to form the content that makes up our universe, from table salt to oxygen to the panoply of colors and smells that surround us. At last, we've reached Reactions, in which Gray once again puts his photography and storytelling to work demonstrating how molecules interact in ways that are essential to our very existence. The book begins with a brief recap of elements and molecules and then goes on to explain important concepts the characterize a chemical reaction, including Energy, Entropy, and Time. It is then organized by type of reaction including Combustion, Photosynthesis, Respiration, Oxidation, and Fermentation. A special section dedicated to chemical cycles includes The Carbon Cycle, The Iron Cycle, and The Lime Cycle.

They say you eat with the eyes. But we now know that smell, texture, temperature, colour and even atmosphere – down to the background music – influence how we perceive flavour.As anyone who has lost their sense of taste will know, flavourless food is dull and monochrome - it is flavour that brings food into full technicolour life. Yet it's not always easy to make something tasty; the secrets to flavour can baffle chefs and scientists alike.Food science expert Dr Stuart Farrimond explores major flavour categories such as salt, acid and heat (from chillies) and how they interact, and profiles all the major foods from individual fruit, veg, herbs and spices to the building blocks such as rice and wheat that give us stapes like bread, pasta, and noodles. With pairing notes for every ingredient, you'll soon be inventing new recipes.
