But rumours are rife saying the black panther is an evil curse. She and her friends have to separete facts, from fiction and find the truth about the evil going on in the forest and in the surrounding community.
Wie entsteht eine wissenschaftliche Tatsache? Wie stellt sich naturwissenschaftliche Kreativität dar, wenn man sie im Labor des Naturwissenschaftlers beobachtet? Wie verhält sich die handwerkliche Arbeit der Forscherin zu dem, was im veröffentlichten wissenschaftlichen Text steht? Karin Knorr Cetina geht durch das Labor mit den Augen einer Anthropologin, die die Sitten und Gebräuche einer fremden Ethnie mit der Distanz, aber auch der Sympathie des Mitglieds einer anderen Kultur studiert. Dabei zeigt sich, dass man das Unternehmen Wissenschaft mit idealisierten epistemologischen Begriffen nicht besonders gut zu fassen bekommt. Es muss vielmehr aus der Alltagswelt wissenschaftlicher Handarbeit rekonstruiert werden. Ein Klassiker der Wissenschaftssoziologie.
The book covers the spread of conservation agriculture (CA) to regions including Brazil, Argentina, Canada, Australia, Europe and emerging CA destinations in Asia and Africa. Topics covered include the various components of CA, and how their individual and combined implementation influence productivity, soil health and environmental quality under diverse edaphic and climatic conditions. The book will be useful to teachers, researchers, extensionists, farmers, and students interested in environmental quality.

Natural polymers have been utilized extensively in food, pharmaceuticals, cosmetics, textiles, oil drilling and paint industries. Their non-toxic and inexpensive attributes readily enhance their commercial acceptability and make them potent agents in lieu of synthetic polymers. This book explores the opportunistic utility of natural polymers in developing effective drug delivery systems and provides a comprehensive and up-to-date analysis of their source, chemical structure and mechanism of action. Covering novel polymers for drug delivery - in particular extracts from plants, microorganisms and proteins, as well as water soluble and water insoluble biodegradable polymers - it presents an encyclopaedic overview of natural polymers': - quintessential roles in binding drugs towards enhancing bioavailability - modification and derivatization for targeted delivery - role as active drugs Natural Polymers for Drug Delivery is an invaluable resource for researchers, students and industrial scientists in the fields of biochemistry, chemistry, pharmacology and food science. ; This book provides an overview of the source, chemical structure and action mechanism of natural polymers. Focusing on their utility in developing effective drug delivery systems, it covers polymers’ role in binding drugs towards enhancing bioavailability, modification and derivatisation for targeted delivery, and modification as active drugs. ; 1: Natural Polymers for Drug Delivery: An IntroductionSection I: Drug Delivery Based on Different Classes of Polymers2: Cellulose-based Polymeric Systems in Drug Delivery3: Hydrocolloids-based Hydrogels in Drug Delivery4: Water Soluble Biodegradable Polymers for Drug Delivery5: Polysaccharide-based Drug Carriers6: Polymer-based Nanoparticles for Drug Delivery Systems and Cancer Therapeutics7: Polymer Nanocomposite-based Biosensors for Drug Delivery ApplicationsSection II: Polymeric Interaction and Conjugates8: Polymer-Drug Conjugates: Targeted Drug Delivery9: Protein-Drug Conjugates: A New Class of Biotherapeutics10: Microencapsulation for Controlled Gastrointestinal Delivery of Probiotics and PrebioticsSection III: Disease-specific Drug Delivery Systems11: Chitosan in Drug Delivery and Targeting for Cancer Treatment12: Polymers as Biodegradable Matrices in Transdermal Drug Delivery13: Ocular Drug Delivery Systems14: Natural Polymers Targeting Habitual Disease15: Bioengineered Wound and Burn Healing Substitutes: Novel Design for Biomedical and General Applications
Dementias are brain disorders that impair memory, thinking, behavior, and physical activity. Alzheimer's disease is the most common form, affecting 50 to 60 percent of dementia patients, and yet the exact cause of Alzheimer's and how best to detect it early remain unknown. Alzheimer's Disease and Other Dementias, Second Edition provides helpful clarification of this group of diseases and their specific types. It explains how to recognize the symptoms of dementia or Alzheimer's disease, how these disorders are diagnosed, the latest theories about their cause, and how they can be treated. Also covered are the outlook for future prevention and treatment and resources providing further information for those seeking help coping with dementia.
Child Abuse and Stress Disorders, Second Edition examines the phenomenon of stress and how it affects people psychologically, emotionally, and physically with an in-depth look at the effects of child abuse and neglect.

Several chapters discuss various types of child abuse and neglect and their long-term effects on mental and physical well-being in childhood and beyond. This volume sheds light on the devastating, chronic influence of traumatic experiences on both children and adults and methods for treating them.
Schizophrenia is a severe and debilitating disease of the brain that affects approximately 1 percent of the population worldwide. This psychotic disorder causes severe mental disturbances that disrupt thought patterns, speech, and regular daily activities of life. Those with schizophrenia can exhibit odd or disturbing behaviors. The disorder can be devastating to those who suffer from it, as well as frightening and exhausting for their families. However, recent research on the causes of schizophrenia, its diagnosis, and the effectiveness of different treatments provides a more hopeful outlook for those affected. Schizophrenia, Second Edition describes the symptoms of this disease and the impact it has on patients and their loved ones. It also examines how scientific studies seek to untangle the multiple causes of schizophrenia and reviews research on how well drug and nondrug treatments work for schizophrenia patients.
Addiction affects millions of people throughout the United States, and the numbers are growing. But what exactly is this phenomenon? Is it a physical or psychological illness? A poor choice? Or a medical disease? The United States' two biggest addictions, cigarettes and alcohol, cost our health care system more than $100 billion every year, and in recent years opioid addiction has spread and claimed thousands of lives. Addiction, Second Edition explores the mechanics of addiction, its root causes, and how it touches the lives of every member of society, including users, nonusers, and friends and relatives of users. This eBook also explains addiction as a medical and behavioral phenomenon, defines drug use and behaviors that can reach compulsive levels, and illustrates various ways to treat addictions.
Depression and bipolar disorder are part of a group of mental illnesses called mood disorders. People with these conditions may experience unusual and extremely low or elevated moods as well as unpredictable mood swings. These disorders can also affect one's physical well-being. For many years people who suffered from mood disorders such as depression or bipolar disorder were stigmatized for their problems. Most doctors and medical scientists now believe that these illnesses are caused by chemical imbalances in the brain and can be treated with medication and talk therapy. Depression and Bipolar Disorder, Second Edition provides the basic facts needed to understand the different types of depression and related disorders and what defines them, including the typical symptoms, possible causes, and current treatments.
This important book provides new understandings of how the politics of memory impacts peace in societies transitioning from a violent past.
