Nose Dive
The ultimate guide to the smells of the universe - the ambrosial to the malodorous, and everything in between - from the author of the acclaimed culinary guides On Food and Cooking and Keys to Good CookingFrom Harold McGee, James Beard Award-winning author and leading expert on the science of food and cooking, comes an extensive exploration of the awe-inspiring world of smell. In Nose Dive, McGee takes us on a sensory-filled adventure, from the sulfurous nascent earth more than four billion years ago, to the sweetly fragrant Tian Shan mountain range north of the Himalayas, to the keyboard of your laptop, where trace notes of formaldehyde escape between the keys. We'll sniff the ordinary (wet pavement and cut grass) and extraordinary (fresh bread and chocolate), the delightful (roses and vanilla) and the unpleasant (spoiled meat and rotten eggs). We'll smell each other. We'll smell ourselves.Through it all, McGee familiarizes us with the actual bits of matter that we breathe in-the molecules that trigger our perceptions. Beginning with the origins of those molecules in interstellar space, McGee moves onward through the smells of our planet, the air and the oceans, the forest and the meadows and the city, all the way to the smells of incense, perfume, wine, and food. Here is a story of the world, of all of the smells under our collective nose. A work of astounding scholarship and originality, Nose Dive distills the science behind the smells, and reveals how our sense of smell has the power to trigger in us feelings that are the very essence of being alive.

Soil chemistry: lesson proposals for secondary schools
Soil is present in the lives of all human beings and we depend on it for our survival. In view of this, the general aim of this work was to draw up proposals for sequences of lessons that could be taught by teachers of the Chemistry curriculum component to students in the first year of secondary school, with the central theme being 'soils' and specifically to show the importance of handling soil correctly; to identify the Chemistry content that can be worked on in secondary school.

Assessment of soil contamination
Every year the consumption of petroleum products and biofuels, especially diesel oil and biodiesel, increases worldwide. In order to meet demand, there has been an increase in the number of petrol stations, making the installation of underground tanks inevitable. However, due to small fuel leaks that occur in tanks, and mechanical or human failures in unloading operations, there have been many cases of soil contamination, thus contributing to environmental degradation. In view of this, the aim of this study was to qualitatively analyze samples of soil possibly contaminated by petroleum products (diesel oil) and biofuels (biodiesel) collected around gas stations in the city of Porto Seguro (BA) using Fourier Transform Infrared Spectroscopy (FTIR) associated with the pattern recognition method (PCA). The analysis showed that there are regions of the spectrum in which the absorption intensity of biodiesel is appreciable, while that of diesel oil is negligibly small.

Alchemical Matters
Ever wonder what the alchemists were talking about? Alchemical Matters: Essays on the Precursor to Modern Chemistry provides in-depth background information, useful hints, and tips. The collection of essays delves into the possible chemistry of the alchemist's recipes for the transmutation of metals and the concocting of elixirs, the apparatus employed, and the theories used to explain their observations. Alchemical Matters, then, is a useful source of general information for the beginning student of alchemy but is, as well, a valuable interpretative tool for those pursuing a more in-depth study of the enigmatic precursor to modern chemistry. Author Keith Schuette is a 1977 graduate of the University of Missouri-Rolla (currently the Missouri University of Science and Technology), where he earned a BS degree in Metallurgical Engineering. He also holds a Master of Divinity degree from Eden Theological Seminary in St. Louis. Now retired, his career involved employment as a metallurgist, a quality manager, and a part-time instructor. A father of a daughter and a son, and a grandfather of six, he currently resides with his wife, Linda, in West Bend, Wisconsin. He is also the author of Beta Delta of Alpha Chi Sigma (A History), the professional chemistry fraternity.

Soil and Water Analysis of Kasalganga River
This book deals with the Soil and Water analysis. T The main purpose is to identify the different parameters of soil and water. It is actual related with the environmental pollution. Globally, there are many challenges regarding climate change and its' impacts of landdegradation and food and water scarcity. Recently, and with increasing population and their needs of water and food, it was a necessity for finding fast and advanced solutions for dealing with these problems. Moreover, soil and water are considered as the main sources of life on the earth. Therefore, understanding of the nature of these resources is very important in order to knowing the possibility of their evaluation and management. This mission starts with selecting the area which needed to be studied for the objective of evaluating physical, chemical and biological characteristics. These characteristics describe mainly the soil and water qualities which located in a specific site under investigation, and also the fertility status as well as land capability for the agricultural production. Detecting the land use in a specific location is a very necessary for knowing the suitable approach.

Sustainable Production of Biosurfactants
One of the ways to reduce the costs of producing biosurfactants is to add value to the biomass and extract of the producing microorganism. For example, the in vitro production of surfactins has a low yield and involves growing Bacillus subtilis in synthetic media using expensive substrates. During growth, surfactin and other lipopeptides and enzymes important to the pharmaceutical industry, food industry and ethanol production, such as alpha-amylase, lipase and cellulase, are produced and secreted into the culture medium. At the end of microbial growth, the extract is separated from the biomass by centrifugation. This biomass, which would otherwise be discarded, is a source of proteins and lipids, with potential applications for the synthesis of other surfactants, and can also be used for environmental decontamination. The main objective of this work is to present alternatives to reduce the costs of surfactin production.

Direct and concentrated incorporation of CaCO3
This work investigates high-density polyethylene (HDPE) composites reinforced with calcium carbonate (CaCO¿), highlighting the importance of Masterbatches for efficient dispersion of CaCO¿ in the polymer matrix. The preparation of the Masterbatches resulted in a homogeneous mixture, optimizing processing conditions and stabilizing the mechanical and thermal properties of the composite, even with high filler ratios.The addition of CaCO¿ up to 20% via a concentrate improved the flowability index, facilitating composite processing, while maintaining a stable Vicat temperature, a sign of uncompromised thermal resistance. Infrared analyses confirmed a homogeneous dispersion of CaCO¿ in the polymer matrix.Mechanically, composites with up to 15% CaCO¿ via concentrate retained satisfactory properties while improving processability. However, at 20%, a reduction in ductility is observed, although stiffness and mechanical strength remain preserved. This indicates that the composite becomes less deformable before fracture at high loading rates.

Frostbite
"Engrossing...hard to put down." — The New York Times Book Review“Frostbite is a perfectly executed cold fusion of science, history, and literary verve . . . as a fellow nonfiction writer, I bow down. This is how it's done.” — Mary Roach, author of Fuzz and StiffAn engaging and far-reaching exploration of refrigeration, tracing its evolution from scientific mystery to globe-spanning infrastructure, and an essential investigation into how it has remade our entire relationship with food—for better and for worseHow often do we open the fridge or peer into the freezer with the expectation that we’ll find something fresh and ready to eat? It’s an everyday act—but just a century ago, eating food that had been refrigerated was cause for both fear and excitement. The introduction of artificial refrigeration overturned millennia of dietary history, launching a new chapter in human nutrition. We could now overcome not just rot, but seasonality and geography. Tomatoes in January? Avocados in Shanghai? All possible.In Frostbite, New Yorker contributor and cohost of the award-winning podcast Gastropod Nicola Twilley takes readers on a tour of the cold chain from farm to fridge, visiting off-the-beaten-path landmarks such as Missouri’s subterranean cheese caves, the banana-ripening rooms of New York City, and the vast refrigerated tanks that store the nation’s orange juice reserves. Today, nearly three-quarters of everything on the average American plate is processed, shipped, stored, and sold under refrigeration. It’s impossible to make sense of our food system without understanding the all-but-invisible network of thermal control that underpins it. Twilley’s eye-opening book is the first to reveal the transformative impact refrigeration has had on our health and our guts; our farms, tables, kitchens, and cities; global economics and politics; and even our environment.In the developed world, we’ve reaped the benefits of refrigeration for more than a century, but the costs are catching up with us. We’ve eroded our connection to our food and redefined what “fresh” means. More important, refrigeration is one of the leading contributors to climate change. As the developing world races to build a US-style cold chain, Twilley asks: Can we reduce our dependence on refrigeration? Should we? A deeply researched and reported, original, and entertaining dive into the most important invention in the history of food and drink, Frostbite makes the case for a recalibration of our relationship with the fridge—and how our future might depend on it.
