In the past nuclear medicine has tended to develop in cycles governed by the development of new radiopharmaceuticals followed or preceded by advances in instrumentation. The development of alternative techniques, such as X-Ray Computer Tomography, NMR Imaging and Ultrasound have also had a stimulating effect and pointed the way to new developments. The development of Positron Emission Tomography, while in itself of limited application because of high costs involved, provided a great deal of information which led to the development of new organ or disease specific, single photon emitting radiopharmaceuticals together with tomographic Gamma cameras, whereby detailed information on the biodistribution of the reagents could be obtained with accurate spatial resolution presented in a form suitable for comparison with the other imaging modalities. This technology, known as Single Photon Emission (Computer) Tomography (SPECT or SPET) is now an essential tool in nuclear medicine. The volume presents a basic guideline to the technology involved and discusses the application of the method to the investigation of various anatomical regions of the body. The book is an aide memoire to the routine practitioner and a source of information for other medical specialists.

A comprehensive presentation of wicking models developed in academia and industry, Wicking in Porous Materials: Traditional and Modern Modeling Approaches contains some of the most important approaches and methods available, from the traditional Washburn-type models to the latest Lattice-Boltzmann approaches developed during the last few years. It provides a sound conceptual framework for learning the science behind different mathematical models while at the same time being aware of the practical issues of model validation as well as measurement of important properties and parameters associated with various models. Top experts in the field reveal the secrets of their wicking models. The chapters cover the following topics: Wetting and wettability Darcy's law for single- and multi-phase flows Traditional capillary models, such as the Washburn-equation based approaches Unsaturated-flow based methodologies (Richard's Equation) Sharp-front (plug-flow) type approaches using Darcy's law Pore network models for wicking after including various micro-scale fluid-flow phenomena Studying the effect of evaporation on wicking using pore network models Fractal-based methods Modeling methods based on mixture theory Lattice-Boltzmann method for modeling wicking in small scales Modeling wicking in swelling and non-rigid porous media This extensive look at the modeling of porous media compares various methods and treats traditional topics as well as modern technologies. It emphasizes experimental validation of modeling approaches as well as experimental determination of model parameters. Matching models to particular media, the book provides guidance on what models to use and how to use them.

Die reeks is volgens die Nasionale Kurrikulum- en Assesserings beleidsverklaring (“CAPS”) geskryf. ’n Moontlike werkskedule is ingesluit. Elke hoofstuk begin met ’n oorsig van wat onderrig word en die hulpbronne wat jy benodig. Daar is advies oor die voorgestelde pas wat jou sal help om die hele jaar se werk betyds af te handel. Ons gee by elke onderwerp raad oor hoe om konsepte bekend te stel en hoe om leerders met steierwerk voor te berei en te ondersteun. Al die antwoorde word gegee; jy bespaar dus tyd omdat jy nie die oefeninge self hoef uit te werk nie. ’n Volkleurplakkaat en ’n CD propvol hulpbronne is ook ingesluit om jou met onderrig en assessering te help. Addisionele voorbeeldvrae, toetse of assesserings take, wat jy kan kopieer, sal jou help om jou leerders effektief te assesseer.

Spesifiek geskryf om aan al die vereistes van die nasionale Kurrikulum- en Assessering beleidsverklaring (KABV) te voldoen. Sleutelterme word in rooi gedruk as dit vir die eerste keer verskyn. ’n Lys van hierdie terme word ook in rooi aan die begin van elke eenheid of hoofstuk gelys. Nuwe woorde is in blou en word in die kantlyn verduidelik. Aktiwiteite help leerders om te verstaan wat hulle geleer het. 'n Opsomming aan die einde van elke onderwerp help leerders studeer. Die Formele Assesserings taak (FAT) blokkie bevat take wat leerders voorberei vir die wat in die klas voltooi moet word. Vrae aan die einde van elke onderwerp help leerders met hersiening. ‘n Voorbeeld van ‘n eksamenvraestel aan die einde van die boek sal leerders ook help oefen en leer oor alles wat hulle nodig het om te weet.

The large volume requirements for high quality ABO and Rh(D) typing reagents can now be supplied by selected monoclonal antibodies using hybridoma technology. In this book two efficient methods for the industrial production of Monoclonal antibody is described. This products have major advantages in lot-to-lot consistency in both potency and specificity, and have minimal processing requirements-no defibrination, delipidisation or absorption of unwanted anibodies.

Sweet potato (Ipomoea batatas L.) is adaptable to a broad range of agro ecological conditions and fits in low input agriculture. It is highly productive even under adverse farming conditions. Sweet potato is grown in more than 100 countries as a valuable source of food, animal feed and industrial raw material. It is a staple crop in many South East Asian and African countries. The application of new techniques for improvement of sweet potato crops, particularly including the exploitation of somaclonal variation, gene transfer by genetic transformation and somatic hybridization, requires the control of plant regeneration from tissue cultures. In this study different Micropropagation techniques such as Meristem culture for the development of virus free plants, Nodal culture, In vitro conservation or slow growth culture were conducted. .Results indicates that these are the best methods for the improvement of the crop.
