Abstract This paper intends, through a qualitative study to examine and analyze how a particular type of financial firms cooperate, and what this entails. The case study issue which shall be answered is "What does the firms Credit Suisse and Orn &amp; Cie SA gain out of cooperating with each other?". By setting the general theories in the subject joint ventures, partnerships, against the empirical material gathered via interviews and data collection in Geneva, Switzerland  answers to what the cooperation between the two parties has resulted in for the respective companies has been found. The survey shows that the prevailing model of cooperation creates significant benefits for the two companies. At the same time the existing cooperation has meant more risk taking for both companies in general and especially for the smaller company Orn &amp; Cie SA. The current model of cooperation would lead to serious problems for them if it would fall apart and it is essential that the companies continuously keep working to prevent this.

The goal of this model is to create and to implement qualitative model of the signal track of olfactory sensory neuron, including the feedback with a focus on diffusion of substances that allows to conduct more simulations for the better understanding of dynamics of the signal track. This model is expected to be used for the simulation of influencing during the activation of two receptors in firstly defined distance. Model was created and therefore implemented in a programming language Python with the use of library STEPS. Then I have conducted sensitivity analysis by a method Morris OAT on the model, together with an optimization with the usage of change of individual parameters with a great importance on the output of the model. Model is conducting good and biologically comparable results when there are from 10 to 100 active receptors at the beginning of the track. Unfortunately with a lower numbers, the results are not valid and therefore not to be used for the simulation of influencing of two activated receptors. Despite this is a main benefit of the work the model of signal transduction for the whole signal track with an included feedback and emphasis on diffusion. Another benefit is a set of scripts for the sensitivity analysis by a method Morris OAT and optimization.

Radiation and medical drugs are used to fight head and neck cancer, but unfortunately in some cases these treatments cause development of other diseases and injuries. Osteoradionecrosis (ORN) and medical-related osteonecrosis of the jaw (MRONJ) are dreaded late complications in jaws from radiation therapy and medical drugs and cause great suffering to those affected. The full extent of ORN and MRONJ may be difficult to diagnose due to visualizing problems in quantifying boundaries of osteonecrosis and healthy tissues. Maxillofacial surgeons now use radiology and clinical appearance to differ affected bone, which may result in unprecise estimation of the area that is affected. As a possible adjuvant diagnostic procedure, visualizing osteonecrosis by examining neutrophil elastase (NE) activity in jaws was tested in patients. A newly developed positron emission tomography (PET) tracer specific for NE was used for observation and measurement in PET/CT images. An image processing software was used for visualization, segmentation, and analysis. Areas with osteonecrosis were identified in the ORN patients, but not in their entirety and all activity could not be equated with osteonecrosis as undiagnosed areas as well absorbed the tracer. Visualization of MRONJ displayed unexpectedly low activity in the diagnosed area.    The conclusion drawn from the results and the analysis is that NE activity can be found in osteonecrosis patients, but the activity itself does not provide complete information to visualize and quantify the diseased area and it cannot be equated with osteonecrosis. To verify NE activity as osteonecrosis, tissue samples from the affected area need to be collected for histological examination
