Characterization of solution processed,p-doped films using hole-only devices and organic field-effect transistors

We report a solution processed, p-doped film consisting of the organic materials 4,4′,4″-tris(3-methylphenylphenylamino)triphenylamine (MTDATA) as the electron donor and 2-(3-(adamantan-1-yl)propyl)-3,5,6-trifluorotetracyanoquinodimethane (F3TCNQ-Adl) as the electron acceptor. UV–vis–NIR absorption spectra identified the presence of a charge transfer complex between the donor and acceptor in the doped films. Field-effect transistors were used to characterize charge transport properties of the films, yielding mobility values. Upon doping, mobility increased and then slightly decreased while carrier concentration increased by two orders of magnitude, which in tandem leads to conductivity increasing from 4 × 10^?10 S/cm when undoped to 2 × 10^?7 S/cm at 30 mol% F3TCNQ-Adl. The hole density was calculated based on mobility values extracted from OFET data and conductivity values extracted from bulk I–V data for the MTDATA: x mol% F3TCNQ-Sdl films. These films were then shown to function as the hole injection/hole transport layer in a phosphorescent blue OLED.     

Review of Finishing well: Aging and reparation in the intergenerational family.

Reviews the book, Finishing well: Aging and reparation in the intergenerational family by Terry D. Hargrave and William T. Anderson (see record 1992-98532-000). The purpose of this book is to help older people and their families complete life in a more satisfactory way through contextual family therapy. The essence of the contextual approach is to resolve family relationships by building trust and commitment in the family through redressing the imbalance of entitlements and obligations within the family. In this review, the dynamics of family relationships are described and the stages of family therapy as detailed in the book are summarized. In the book, the authors focus on the importance of forgiveness and describe the technique by which they promote forgiveness between family members. According to the reviewer, the book is well written because the therapeutic techniques are clearly illustrated with examples from therapy cases. This book can be enthusiastically recommended to all therapists engaged in therapy with older people, and to those doing family therapy.

Review of The integration of psychotherapies.

Reviews the book, The integration of psychotherapies by Alvin R. Mahrer with a Foreword by John C. Norcross (see record 1989-97512-000). Mahrer has written the book for those who are learning, teaching, supervising, and trying to integrate psychotherapies. In the book he is trying to answer the following questions: What are the various strategies that are used for integrating psychotherapies? How do the several strategies fare comparatively in their feasibility, workability, and chances for success in integrating psychotherapies? What are the likely consequences for the field of psychotherapy of pursuing each of the strategies? Is integration good or bad for the field of psychotherapy? On the basis of his study of the various strategies for integrating psychotherapies, what recommendations are warranted? This book is a valuable intellectual contribution to the development of theory in psychotherapy. The process of attempting to integrate psychotherapies is inevitable, and by producing this thoughtful and scholarly work Mahrer has helped to raise the quality of the integration effort.

The effects of handling and storage on magnesium based implants — First results

The present work aimed to investigate the influence of acetone and formalin as well as the duration and type of storage on magnesium based implants by means of microscopic, μ-computed tomographic, scanning electron microscopic, EDX and metallographic investigations.In contrast to storing in acetone, storage in formalin led to an increase in surface to volume ratio, and a decrease of the volume and the density. The various types of storage exerted no differing effects on the implants but with increasing storage duration, a spreading of oxygen rich areas on the surface, increased precipitations and a decrease in grain size could be observed.     

Cultural heritage in suburban landscape planning: A case study in Southern Norway

In this study we ask how the planning process that coordinates the interests of various sectors on a municipal level affects the cultural heritage assets in suburban landscapes. Special attention is paid to the role the cultural heritage management sector plays in the overall planning processes that take place in such semi-urban regions.A case study is carried out in two suburban areas in Norway, Madla and Nannestad. The case-study design includes various methods; historical map overlay, visual methods, discourse analysis based on qualitative interviews and document studies. The case studies have been performed on two levels: a superior landscape analysis covering the total municipality, and a second and more detailed level.The results from this study show that the protection and caretaking of green interests in land-use planning is not necessarily a protection of cultural heritage interests. Cultural heritage is more to be seen as a derivate interest. Cultural heritage management seldom functions as a premise provider in municipal planning. The findings are discussed in conjunction with the need for comprehensive planning across administrative and disciplinary borders as cities grow into regions. There is also a need for the cultural heritage interests to play a stronger role in planning in order to obtain better preservation of the cultural monuments and landscapes.     

Proteomic serum biomarkers and their potential application in cancer screening programs

Early diagnosis of cancer is of pivotal importance to reduce disease-related mortality. There is great need for non-invasive screening methods, yet current screening protocols have limited sensitivity and specificity. The use of serum biomarkers to discriminate cancer patients from healthy persons might be a tool to improve screening programs. Mass spectrometry based proteomics is widely applied as a technology for mapping and identifying peptides and proteins in body fluids. One commonly used approach in proteomics is peptide and protein profiling. Here, we present an overview of profiling methods that have the potential for implementation in a clinical setting and in national screening programs.
