Purpose: To study the integration of keloid heterograft in hamster (Mesocricetus auratus) cheek pouch. Methods: The sample is formed by 18 male hamsters, heterogenic ones, aged between 10 and 14 weeks. Keloid fragments were obtained from keloid scars of the breast region of adult female mulatto patient. Each hamster received keloid fragments into both of its pouches, in a total of 36 grafted fr...

In this article various pipes used for transporting of gas are introduced and pros and cons of each one are elucidated. The pipes are categorized in three different subgroups including metallic, polymeric and metallic-wire reinforced polymeric pipes. Metallic-wire reinforced polymeric pipes are nominated as the best option for usage in high pressure pipelines transporting natural gas. As a resu...

microwave energy has potential for the efficient heating of minerals. minerals or materials, which couple to microwave energy are called dielectrics and many valuable minerals are found to be dielectric. the mineral ilmenite is one which shows good dielectric heating characteristics. in this paper, the effect of microwave heat energy on the partial reduction of oxidized ilmenite oxidized in ...

recognition of rangeland species with the maximum efficiency and the minimum water usage is very important, since major parts of rangelands in iran are located in arid and semiarid climate. in addition, the rangeland improvement and management on the basis of transpiration rate of rangeland species in different climatic conditions has great importance. the goal of this research is comparison an...

During summer, melt ponds have a significant influence on Arctic sea-ice albedo. The melt pond fraction (MPF) also has the ability to forecast the Arctic sea-ice in a certain period. It is important to retrieve accurate melt pond fraction (MPF) from satellite data for Arctic research. This paper proposes a satellite MPF retrieval model based on the multi-layer neural network, named MPF-NN. Our ...

Group detection is fundamentally important for analyzing crowd behaviors, and has attracted plenty of attention in artificial intelligence. However, existing works mostly have limitations due to the insufficient utilization of crowd properties and the arbitrary processing of individuals. In this paper, we propose the Multiview-based Parameter Free (MPF) approach to detect groups in crowd scenes...

We give an example of a geometry in which the electrostatic force between a point charge and a neutral metallic object is repulsive. The example consists of a point charge centered above a thin metallic hemisphere, positioned concave up. We show that this geometry has a repulsive regime using both a simple analytical argument and an exact calculation for an analogous twodimensional geometry. An...
