Electronic States in Crystals of Finite Size : Quantum confinement of Bloch waves

The theory of electronic states in the traditionally solid state physics is essentially a theory of electronic states in crystals of infinite size. However, any real crystal always has a finite size. This book presents an analytical theory on the electronic states in ideal low-dimensional systems and finite crystals recently developed by the author based on a differential equation theory approach. It gives some exact and general fundamental understandings on the electronic states in ideal low-dimensional systems and finite crystals and provides new insights on some fundamental problems in low-dimensional systems such as the surface states, quantum confinement effects etc, some of them are quite different from what are traditionally believed in the solid state physics community.

Egg yolk oil hydrogel as treatment for burns

Burns are a global public health problem, and the rate of child deaths from burns is currently over 7 times higher in low- and middle-income countries than in high-income countries. Hydrogels consist of water-containing, water-soluble polymers which are linked to form a three-dimensional network. They are breathable and can be used for different types of burns (closed, open, weeping, or dry). By contrast, occlusive ointments, which often have a fatty base, are considered rather unfavorable for burn and are primarily suitable for use on irritated, unburn skin...

Effect of Cranberry in the Treatment of E. Coli

Escherichia coli (E. coli) bacteria normally live in the intestines of healthy people and animals. It may cause severe stomach cramps, bloody diarrhoea, vomiting and UTI. You may be exposed to E. coli from contaminated water or food especially raw vegetables and undercooked ground beef. Healthy adults usually recover from infection with E. coli within a week. Young children and older adults have a greater risk of developing a life-threatening form of kidney failure. Cranberries are a popular superfood. People can consume them in the form of a sauce or a juice. They can also add them to stuffing, casseroles, or dessert. In fact, research has linked the nutrients in cranberries to a lower risk of urinary tract infection (UTI), the prevention of certain types of cancer, improved immune function, and decreased blood pressure

Ecotoxicology, Ecological Risk Assessment and Multiple Stressors

The science of ecotoxicology and the practice of ecological risk assessment are evolving rapidly. Ecotoxicology as a subject area came into prominence in the 1960s after the publication of Rachel Carson's book on the impact of pesticides on the environment. The rise of public and scientific concern for the effects of chemical pollutants on the environment in the 1960s and 1970s led to the development of the discipline of ecotoxicology, a science that takes into account the effects of chemicals in the context of ecology. Until the early 1980s, in spite of public concern and interest among scientists, the assessment of ecological risks associated with natural or synthetic pollutants was not considered a priority issue by most government. However, as the years passed, a better understanding of the importance of ecotoxicology emerged and with it, in some countries, the progressive formalization of an ecological risk assessment process.

Economic Geology of Natural Gas Hydrate

This is the first book that attempts to broadly integrate the most recent knowledge in the fields of hydrate nucleation and growth in permafrost regions and marine sediments. Gas hydrate reactant supply, growth models, and implications for pore fill by natural gas hydrate are discussed for both seawater precursors in marine sediments and for permafrost hydrate. These models for forming hydrate concentrations that will constitute targets for exploration are discussed, along with exploration methods. Thermodynamic models for the controlled conversion of hydrate to natural gas, which can be recovered using conventional industry practices, suggest that a number of different types of hydrate occurrence are likely to be practical sources of hydrate natural gas. Current progress in the various aspects of commercial development of hydrate gas deposits are discussed, along with the principal extractive issues that have yet to be resolved.

Eating disorders

What is an Eating Disorder (ED)? Eating disorders are a type of serious mental health condition characterized by severe disturbances in eating behaviors and related to persistent eating behaviors that negatively impact your health, your emotions and your ability to function in important areas of life. Most eating disorders involve focusing too much on your weight, body shape and food, leading to dangerous eating behaviors. These behaviors can significantly impact your body's ability to get appropriate nutrition. Eating disorders can harm the heart, digestive system, bones, and teeth and mouth, and lead to other diseases. Eating disorders affect several million people at any given time, ED often develop in the teen and young adult years, although they can develop at other ages. Eating disorders can affect people of all genders, ages, races, religions, ethnicities, sexual orientations, body shapes, and weights.

Early Public Libraries and Colonial Citizenship in the British Southern Hemisphere

This Pivot book is a comparative study of six early colonial public libraries in nineteenth-century Australia, South Africa, and Southeast Asia. Drawing on networked conceptualisations of empire, transnational frameworks, and ‘new imperial history’ paradigms that privilege imbricated colonial and metropolitan ‘intercultures’, it looks at the neglected role of public libraries in shaping a programme of Anglophone civic education, scientific knowledge creation, and modernisation in the British southern hemisphere. The book’s six chapters analyse institutional models and precedents, reading publics and types, book holdings and catalogues, and regional scientific networks in order to demonstrate the significance of these libraries for the construction of colonial identity, citizenship, and national self-government as well as charting their influence in shaping perceptions of social class, gender, and race. Using primary source material from the recently completed ‘Book Catalogues of the Colonial Southern Hemisphere’ digital archive, the book argues that public libraries played a formative role in colonial public discourse, contributing to broader debates on imperial citizenship and nation-statehood across different geographic, cultural, and linguistic borders.
