Overcoming Limitations

Organic electronic devices are considered as one of the best candidates to replace conventional inorganic electronic devices due to their electronic conductive functionality, low-cost production techniques, the ability to tune their optical and electronic properties using organic chemistry, and their mechanical flexibility. Moreover, these systems are ideal for bioelectronic applications due to their softness, biocompatibility, and most importantly, their electronic and ionic transport. Indeed, these materials are compatible with biological tissues and cells improving the signal transduction between electronic devices and electrically excitable cells. As ions serve as one of the primary signal carriers of cells, they can selectively tune a cell’s activity; therefore, an improved interface between electronics and biological systems can offer several advantages in healthcare, e.g. the development of efficient drug delivery devices. The main focus of this thesis is the development of electronic delivery devices. Electrophoretic delivery devices called organic electronic ion pumps (OEIPs) are used to electronically control the delivery of small ions, neurotransmitters, and drugs with high spatiotemporal resolution. This work elucidates the ion transport processes and phenomena that happen in the ion exchange membranes during ion delivery and clarifies which parameters are crucial for the ion transport efficiency of the OEIPs. This thesis shows a systematic investigation of these parameters and indicates new methods and OEIP designs to overcome these challenges. Two novel OEIP designs are developed and introduced in this thesis to improve the local ion transport while limiting side effects. OEIPs based on palladium proton trap contacts can improve the membrane permselectivity and optimize the delivery of γ-aminobutyric acid (GABA) neurotransmitters at low pH while preventing any undesired pH changes from proton transport in the biological systems. And OEIPs based on glass capillary fibers are developed to overcome the limitations of devices on planar substrates, related to more complex and larger biologically relevant ion delivery with low mobility for implantable applications. This design can optimize the transport of ions and drugs such as salicylic acid (SA) at low concentrations and at relatively much higher rates, thereby addressing a wider range of biomedically relevant applications and needs.

There are many books that deal with pregnancy and maternity, and a large number of magazines and articles on paediatric nursing that examine these subjects from different points of view. This volume is not a manual and is not intended to explain to future parents what to do and what to avoid. The objective is rather to look at the most significant and problematic aspects of this delicate phase of a woman's life and that of a couple. It seeks to offer a key to understand the deep significance and complexity of the path to follow to become parents and to face fears linked to the difficulty of procreation, using the tools of observation and psychoanalytic listening. Reviewing several experiences of clinical work, the authors offer reflections on the personal experiences of women and couples and the difficulties which can be met when the desire for a child is disappointed. A maternity and parenting project can be frustrated by miscarriages and encounter the fear of infertility. How are the problems of sterility or spontaneous abortion experienced?

Overcoming Obstacles in Drug Discovery and Development uses real-world case studies to illustrate how critical thinking and problem solving skills are applied in the discovery and development of drugs. It also shows how developing critical thinking to overcome issues plays an essential role in the process. Modern drug discovery and development is a highly complex undertaking that requires scientific and professional expertise to be successful. After the identification of a molecular entity for treating a medical condition, challenges inevitably arise during the subsequent development to understand and characterize the biological profile; feedback from scientists is used to fine-tune the molecular entity to obtain an effective and safe product. In this process, the discovery team may identify unexpected safety issues and new medical disorders for treatment by the molecular entity. Invariably inherent in this complex undertaking are miscues, mistakes, and unexpected problems that can derail development and throw timetables into disarray, potentially leading to failure in the development of a medically useful drug. Addressing critical unexpected problems during development often requires scientists to utilize critical thinking and imaginative problem-solving skills. Overcoming Obstacles in Drug Discovery and Development will be essential to young scientists to help learn the skills to successfully face challenges, learn from mistakes, and further develop critical thinking skills. It will also be beneficial to experienced researchers who can learn from the case studies of successful and unsuccessful drug development. Provides real-world case studies in drug discovery and the development of drugs Illustrates the use of critical thinking and problem solving in approaching preclinical and clinical problems in drug discovery and development Illustrates and analyses examples of successes and failures in drug discovery and development that have not previously been reported

"This volume analyzes the impediments that local conditions pose to successful outcomes of nation-building interventions in conflict-affected areas. Previous RAND studies of nation-building focused on external interveners' activities. This volume shifts the focus to internal circumstances, first identifying the conditions that gave rise to conflicts or threatened to perpetuate them, and then determining how external and local actors were able to modify or work around them to promote enduring peace. It examines in depth six varied societies: Cambodia, El Salvador, Bosnia and Herzegovina, East Timor, Sierra Leone, and the Democratic Republic of the Congo. It then analyzes a larger set of 20 major post-Cold War nation-building interventions. The authors assess the risk of renewed conflict at the onset of the interventions and subsequent progress along five dimensions: security, democratization, government effectiveness, economic growth, and human development. They find that transformation of many of the specific conditions that gave rise to or fueled conflict often is not feasible in the time frame of nation-building operations but that such transformation has not proven essential to achieving the primary goal of nation-building -- establishing peace. Most interventions in the past 25 years have led to enduring peace, as well as some degree of improvement in the other dimensions assessed. The findings suggest the importance of setting realistic expectations -- neither expecting nation-building operations to quickly lift countries out of poverty and create liberal democracies, nor being swayed by a negative stereotype of nation-building that does not recognize its signal achievements in the great majority of cases."--Page 4 of cover.

While many textbooks explain the techniques of CBT, few fully explore the issues surrounding their application in real-life practice. This unique book comes to the rescue of anyone struggling with the challenges of practising CBT, whether you are a trainee working under supervision or a qualified practitioner. It examines key obstacles, issues and difficulties encountered over the course of the therapy, illustrated with extensive case examples. Learning objectives, practice exercises and further reading lists help you engage with and relate the issues to your own practice. Acknowledging that people are more complex than just the presenting disorder, the authors consider questions around: o Good practice in assessment and case formulation o The challenge of diagnosis o Key client issues, such as guilt and shame, perfectionism, and inability to tolerate storing feeling o The therapeutic relationship o Organisational factors. This succinct and accessible guide throws a lifebelt to any CBT trainee or therapist struggling under the realities of today's psychotherapy and counselling practice, particularly within NHS settings.

This story is about a quadriplegic man who was shot 7 times by his childhood associate who suffered from a mental health condition by the name of schizophrenia who has failed the system and professional medical team who didnt take him serious as a mandated reporters here in the twin cities.
