"[ABSTRAKDalam fotoproduksi kaon, banyak data eksperimen yang telah didapatkan namunmasih sedikit teori yang dapat menjelaskan hasil tersebut dengan baik. Denganmeneliti peran resonans hyperon dalam fotoproduksi kaon, diharapkan dapatmemahami reaksi ini dengan lebih baik. Penelitian ini menggunakan metodeLagrangian efektif dengan interaksi yang lebih konsisten untuk mencari nilaiamplitudo hamburan, kemudian parameter yang tidak diketahui dalam amplitudohamburan dicocokkan dengan data eksperimen dengan meminimalisasikan nilai2=N. Data eksperimen yang digunakan ialah penampang lintang dan observabelpolarisasi. Hasil yang didapatkan menunjukkan nilai yang lebih sesuai dengan dataeksperimen, terutama pada daerah sudut mundur.ABSTRACTKaon photoproduction has been investigated and experimented but still few theoriescan explain it well. Investigating hyperon resonance in kaon photoproduction mayprovide a better explanation about this process. This study was conducted by usingan effective Langrangian method with consistent interaction to calculate scatteringamplitude, then the unknown parameters in scattering amplitude would be fittedwith experimental data by minimizing 2=N value. Experimental data which isused are cross-section and polarization observable. The results showed values moreprecise with the experimental data, especially at backward angle., Kaon photoproduction has been investigated and experimented but still few theoriescan explain it well.

"This volume provides a comprehensive overview of recent developments in magnetic particle imaging (MPI), a novel imaging modality. Using various static and oscillating magnetic fields, and tracer materials made from iron oxide nanoparticles, MPI can perform background-free measurements of the particles’ local concentration. The method exploits the nonlinear remagnetization behavior of the particles and has the potential to surpass current methods for the detection of iron oxide in terms of sensitivity and spatiotemporal resolution. Starting from an introduction to the technology, the topics addressed include setting up an imaging device, assessment of image quality, development of new MPI tracer materials, and the first preclinical results.
