Data marketplaces are the digital platforms on which data providers and buyers exchange data and the marketplace supports the security of transactions and also ensures the execution of payments while the privacy preservation of the users is guaranteed. This study aimed to design a business model classification framework for health data marketplaces. To do so, a relevant business model ontology framework named STOF was selected as a conceptual framework to conduct a taxonomy introduced by Nickerson (2013). Finally, a business model classification framework including 22 dimensions and 84 specifications grouped under 4 construct blocks of S, T, O, and F was generated. The findings of this study can promote the knowledge on health data marketplaces business models on one hand, and on the other hand researchers and practitioners can conduct their researches or businesses using the suggested framework.

C - band Patterns and karyology are discussed for two Iranian species of Fritillaria subgenus petilium. F. imperialis and F. raddeana. All populations showed a similar somatic chromosome number (2n=24). The karyotype formula for F. imperialis was 2n=2x= 24= 4m+8t+ 12st and for F. raddeana was 2n=2x= 24= 4m + 2sm + 8t + 10st. The bands were few and located at intercalary, telomeric, centromeric and rarely secondary constriction regions.F. raddeana differs from F.imperialis in the possession of SAT - submetacentric chromosome, white thick subtelomeric heteromorphic band in their short arms, adjacent to the satellite. Further aspects of banding patterns, band heteromorphy, chromocenters and the role of C- banding in cytotaxonomy are discussed.

Biosystematic study was performed on several Solanum species native to Iran. Cytological analysis revealed presence of 2n = 24, 48 and 72 chromosome number in the species/populations studied. Karyotypic studies revealed the role played by polyploidy and structural changes of chromosomes during species diversification. The somatic chromosome number of S. persicum is reported for the first time. Numerical analysis of morphological characters and SDS-P AG E protein bands supported the classical taxonomic treatment of the genus, providing evidence for the species inter-relationships.

To study the relationships between pollution emitted by fossil fuels and urban development, six cities of Golestan province have been selected. The density of emitted materials such as SO2, Nox, CO, HC and SPM (suspended particle material) have been estimated by using JICA (1997) scale and also the related factors such as climate, topography and city area were considered to realize the capacity of cities air. In the other hand the development factors such as population, city area and constructed area for urbanization in the same time period have been estimated. The data analysis resulted that the air pollutants were increasing with urban development. There was linear correlation between CO and SO2 content of air cities development indices.

Appropriate Industrial Location plays an important role in the success and performance of an industry. In this paper we have studied the location of industries in rural areas of Mazandaran province. We find that only four out of nine cases are in our priority lists of the study. This indicates that the present location chosen might probably be one of the main problems of these industries. Therefore, non-economic factors may have been influential in determining the Location of industry in the rural areas of the province.
