Adsorption on Mesoporous Metal-Organic Frameworks in Solution for Clean Energy, Environment and Healthcare

by Alexander Samokhvalov

Adsorption and desorption in solution play significant roles in separations, detoxification of waste streams, in purification, chromatography, heterogeneous catalysis, metabolism of medicinal drugs, and beyond. Metal-Organic Frameworks (MOFs) are well-ordered 3-dimensional hybrid organic-inorganic polymers which contain metal cations and the structure-building organic "linker" units. Mesoporous MOFs with pore sizes 2-50 nm are particularly suitable for adsorption and adsorption-based separations of large molecules of organic and bio-organic compounds. Thousands of organic compounds and, in particular, aromatic and heterocyclic compounds are widely used as feedstock for industrial chemical synthesis, as fine chemicals, major components of liquid fossil fuels, dyestuffs, industrial solvents, agricultural chemicals, medicinal drugs, pharmaceuticals and personal care products (PPCPs), and active pharmaceutical ingredients (APIs). There is a strong interest towards synthesis, characterization and studies of both known and newly synthesized mesoporous MOFs for adsorption in solution to achieve the high adsorption capacity, selectivity, and the possibility of multiple regeneration of "spent" sorbent. This book covers experimental fundamental research on using mesoporous MOFs in emerging applications of major industrial, environmental and academic importance, especially purification of water and liquid fossil fuels and in advanced biomedical technologies.

Adult Crying: A Biopsychosocial Approach

by Ad J.J.M. Vingerhoets Randolph R. Cornelius

Crying is a typical human expression of emotion. Surprisingly, until now little scientific attention has been devoted to this phenomenon. Many textbooks on emotion fail to pay attention to it, and in scientific journals there are hardly any contributions focusing on this behavior. In contrast, there is much interest from the lay public, allowing pseudo-scientists to formulate theories that have little or no scientific basis. Is there any evidence in support of statements that crying is healthy or that not crying may result in toxification? How do people react to the crying of others? Is crying important for the diagnosis of depression, and if so, how? This book aims to fill this gap in scientific literature. Crying is discussed from several perspectives and specific attention is given to methodological issues and assessment. Each chapter provides a review and a summary of the relevant scientific literature.

Adult Learning Disorders: Contemporary Issues

by Lorraine E. Wolf

Recent advances in neuroimaging and genetics technologies have enhanced our understanding of neurodevelopmental disorders in adults. The authors in this volume not only discuss such advances as they apply to adults with learning disorders, but also address their translation into clinical practice. One cluster of chapters addresses developmental concerns as children and adolescents with learning disorders approach young adulthood. Experts discuss dyslexia, language-based and writing disorders, perhaps the most widely studied group of learning disorders, from the point of view of neuroimaging and genetic underpinnings. Chapters on the neuroscience of nonverbal, math and executive function disorders are also included. Clinically-oriented chapters with case studies, recommendations for accommodation, and considerations for evaluation follow. Study of specialized populations - such as late high school students, college, medical and law students - further demonstrate how our expanded knowledge base may be applicable to clinical practice. The heterogeneity of adults with learning disorders, the complexity of their clinical presentation and co-existing disorders are addressed from both a scientific and clinical point of view demonstrating how empirical research and clinical practice inform each other. This volume will enhance the practice of clinicians and educators working with adults with neurodevelopmental disorders, as well as providing essential current information for researchers of adults with learning disorders.

The monograph begins with a section that examine the basic biology of adult stem cells, including chapters on the emerging role of microRNAs in regulating their fate and the molecular mechanisms that govern their self-renewal, the book moves on to analyze the varying methodologies employed in characterizing these elusive elements of our genetic make-up. The second section details in-vivo lineage tracing of tissue-specific stem cells, explores the neural stem cell paradigm, and considers the function of ABC transporters and aldehyde dehydrogenase in adult stem-cell biology. The final section shifts the focus to the life-span regulation and immortalization and features a chapter on the cancer stem cell paradigm. This is an authoritative volume on one of the frontiers of genetic research, and will serve as a valuable resource, not just for established scientists but also for those now entering the field of stem cell biology.

Adult Stem Cells (Stem Cell Biology and Regenerative Medicine)

by Kursad Turksen

Adult Stem Cells, second edition, takes a critical look at issues concerning the developmental or differentiation potential for a variety of tissue types and for specific adult stem cell types. Since the first edition appeared a decade ago, our understanding of adult stem cells, and more specifically tissue-specific adult stem cells, has advanced tremendously. And an increased interest in regenerative medicine and potential stem cell applications has driven a quest for better understanding of stem cell biology. In turn, this has spawned much activity on generation and utilization of more and better reagents to identify and isolate stem cells and stem cell-like subpopulations, and on assays elucidating their developmental or differentiation potential and functional integration with host tissues and organs. In this fully updated new edition, chapters cover topics ranging from signaling pathways maintaining stemness in hematopoietic cells to regeneration after injury and endocrine mechanisms underlying the stem cell theory of aging. Other chapters cover stem cells by organ or system including pituitary, cardiac, epithelial, teeth, lung, ovary, prostate, liver, and many more. Importantly, the authors of the chapters have not only summarized their successes, but have also summarized some of the difficulties that each particular field is still facing with respect to maximizing the utility of stem cells in clinical settings. Collectively, they impart both the excitement and challenges facing stem cell utilization for repair and regeneration making this book essential reading for those involved in stem cell research as well as those involved in clinical assays.

Adulteration in Herbal Drugs: A Burning Issue

by Shabnum Shaheen Sehrish Ramzan Farah Khan Mushtaq Ahmad

Substitution and adulteration in traded herbal raw material are common practice in the herbal industry due to the extinction of required species, deforestation and incorrect taxonomical identification. Herbalists have adopted methods to create high quality adulteration which cannot be detected without performing microscopic examination or chemical analysis. It is difficult to establish specific quality control standards due to the complex nature and innate unpredictability of the chemical constituents of medicinal herbs.The main parameters for measurement and adulteration prevention in medicinal herbs are morphological and microscopic investigation, chemical profiling and DNA barcoding. The need for highly sensitive and more effective approaches for the authentication of medicinal herbs is necessary in order to promote the acceptance of herbal products. Adulteration In Traditional Medicinal Herbs is aimed at promoting awareness of adulteration in traditional herbal medicines for the worldwide scientific community. Parameters are established for the prevention of adulteration through classical and modern scientific tools. Valuable case studies are presented based on ethno-medicinal surveys performed in many herbal markets in Pakistan. Collections of various samples were obtained from these shops then compared with the original plants collected from field. Various phytochemical, organoleptic and DNA barcoding techniques were used in order to detect adulteration in the marketed herbal samples. This book is the first of its kind and is aimed at helping the scientific community to identify particular medicinal plants which are facing adulteration problems in herbal markets and to estimate the extent of adulteration and substitution in commonly used medicinal herbs.

Advance Metadata Fair: The Retention and Disclosure of 4G, 5G and Social Media Location Information, for Law Enforcement and National Security, and the Impact on Privacy in Australia (Law, Governance and Technology Series #44)

by Stanley Shanapinda

This book outlines the legal powers of a major Western nation – Australia – to collect and use location information. Mobile service and social media service providers now have the ability to track, record and store more precise location information. Unlike 4G, 5G mobile communications require that cell towers and antennas be in much closer proximity; as a result, the location data can reveal more personal and sensitive information about individual citizens. Despite this aspect, service providers are required to disclose the data to the authorities, without the need for a judicial warrant. This book was written from the perspective of big location data software analytics, a capability that makes it possible to combine various location data points to create a profile on a given individual’s movements, habits, and political, religious and ideological orientation. In this regard, privacy is poorly protected. The rationale used to justify the powers was enforcing serious crimes – terrorism offences. Location data can now be retained for at least two years and be collected to investigate even minor offences. This can be done without the person being reasonably suspected of a criminal offence – when the individual is simply determined to be a person of interest. This poses legal risks to vulnerable communities. And yet, such investigative techniques are deemed lawful and reasonable. At a time when national security is so broadly defined to include economic issues, which in turn overlap with climate change and environmental protection, these legal powers should be reassessed. The book clarifies the complex rules that every citizen must know in order to have agency. Further, it calls upon authorities to reflect and to self-regulate, by making the conscious decision to surrender some of their powers to review by the independent judiciary. Without the requirement for a judicial warrant or judicial review, the powers are unfairly broad. The book pursues an interdisciplinary approach to assess the functionality of mobile telecommunications in direct relation to law enforcement powers and existing judicial precedents. Further, it offers a unifying techno-legal perspective on a complex issue touching on modern privacy law and communications technologies.

Advanced and Applied Studies on Ultra-Trace Rare Earth Elements (Springer Theses)

by Chung-Che Wu

This book provides two state-of-the-art quantitative techniques to determine ultra-trace rare earth elements (REEs) in natural carbonates using solution nebulization-inductively coupled plasma mass spectrometry (SN-ICPMS) and laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS) with respective applications were presented in this dissertation. These techniques were applied to natural carbonates, including corals and stalagmites, to understand volcano eruptions and the impacts on modern biosystem and paleoclimate regimes. In the first SN-ICPMS protocol, direct measurements for femtogram quantity carbonate samples without chemical separation steps can offer accurate and high-precision analysis (±1.9-6.5%, 2σ) with a high sample throughput of 8-10 samples/hr routinely. Application to modern Porites corals collected from South China Sea region, the anomalies of REE contents and Al/Ca ratios associated with micro-domain images, register modern coral reefs could be exacerbated by volcanic eruptions. In the second protocol, a high-sensitivity quantitative open-cell LA-ICPMS technique has been established to allow direct sampling on stalagmite surface in the atmospheric air. This technique improved limits of detection down to sub-ng/g range and promises analyses of carbonate REE profiles at the single digit parts-per-billion (ppb) levels. Application to a 15-cm stalagmite collected from East Timor reveals two peaks of REE contents by at least one order of magnitude, possibly due to volcanic ash preserved in stalagmite. Both improved SN-ICPMS and LA-ICPMS techniques highlight the high-sensitivity and high-temporal-resolution carbonate REE analyses for corals and stalagmites, with great potential to other natural carbonates such as travertine, tufa, and flowstone, benefit our understanding of paleoclimatic and paleoenvironmental dynamics.
