PREMISE Biological invasions increasingly threaten native biodiversity and ecosystem services. One notable example is the common reed, Phragmites australis, which aggressively invades North American salt marshes. Elevated atmospheric CO2 nitrogen pollution enhance its growth facilitate invasion because P. australis responds more strongly to these enrichments than do species. We investigated how...

The accuracy and consistency of the delivery of ethanol to cultured cells is important to determine effects on morphologic, biochemical and physiologic alterations. Open and closed chamber systems were evaluated to determine cytotoxic vs sublethal, potentially teratogenic effects on neonatal rat cardiac myocytes. The open system employed a variety of cell culture vessels. Cardiac cells were exp...

Thermal decomposition of two coal samples obtained from Top Seam Sibi (TSS) and Sore Range Quetta (SRQ) coal fields in their raw and acid washed forms were carried out in an open type tubular pyrolyzer coupled to a gas chromatograph with FID. Elemental analyses were carried out with Scanning Electron Microscope-Energy Dispersive X-rays (SEM-EDX) analyzer. Effect of inherent mineral contents...

In this paper we report a microfluidic model to simulate the bronchi of a cystic fibrosis (CF) patient. The biochip is comprised of two cell culture chambers separated by a membrane. On top of the membrane an alginate hydrogel is formed in order to simulate the thick mucus layer spotted in a CF bronchi. In the bottom chamber a monolayer of epithelial cells are cultured to simulate the bronchi t...

The actual design of the muon detector system consists of 6 hadron absorber layers (iron plates of thickness 20, 20, 20, 30, 35, 100 cm) and 15-18 gaseous tracking chambers located in triplets behind each iron slab. The geometry of the muon system is presented in figure 1: the side view of the full system (top), the side wiew of one gap with detector layers (bottom left), and the side view of o...

INTRODUCTION The sets of nested DNA fragments generated by DNA sequencing methods are resolved by electrophoresis through thin denaturing polyacrylamide gels. WARNING Large voltages are passed through DNA-sequencing gels at substantial amperages. More than enough current is used in these gels to cause severe burns, ventricular fibrillation, central respiratory arrest, and asphyxia due to paraly...

The cloning is one of the most promising biotechnologies today. The project aims to automate every process required in the cloning, i.e. supplying, cutting, removing, filtering, assembling and fusing, on the basis of micro robotics technology. The processes are performed on a micro chip consisting of micro channels and chambers in which oocytes and membranes flow and are manipulated. A whole sy...

The huge amount of interlinked information referring to different domains, provided by the Linked Open Data (LOD) initiative, could be e↵ectively exploited by recommender systems to deal with the cold-start and sparsity problems. In this paper we investigate the contribution of several features extracted from the Linked Open Data cloud to the accuracy of di↵erent recommendation algorithms. We f...

Canton Ticino in southern Switzerland is exposed to some of the highest concentrations of tropospheric ozone in Europe. During recent field surveys in Canton Ticino, foliar symptoms identical to those caused by ozone have been documented on native tree and shrub species. In Europe, the critical ozone level for forest trees has been defined at an AOT40 of 10 ppm.h O3 (10 ppm.h accumulated exposu...
