High energy hadrons in EAS at mountain altitude

An extensive simulation has been carried out to estimate the physical interpretation of dynamical factors such as , in terms of high energy interaction features, concentrated in the present analysis on the average transverse momentum. It appears that the large enhancement observed for versus primary energy, suggesting in earliest analysis a significant rise of with energy, is only the result of the limited resolution of the detectors and remains in agreement with a wide range of models used in simulations.Comment: 13 pages, 6 PostScript figures, LaTeX Subm. to JPhys

X-ray film chamber with carbon target of Tien-Shan complex array

X-ray films were exposed inside the ionization calorimeter under 74g/sq cm of carbon and 5 cm of lead. The X-ray film chamber area is 35 sq. m. Moving X-ray films were used, 50% of the events, which succeeded to determine incidence time, were identified with corresponding extensive air showers (EAS). For such events the size spectrum of associated EAS was derived. Two methods of energy measurement using X-ray films and ionization calorimeter were compared. The energy transfer from selected hadron to electromagnetic component is illustrated. It is found that in cascades with high energy release into electromagnetic components the hadron component is practically absent

Pyrazole derivatives as polyethylene oxidative destruction stabilizers

The possibility of newly synthesized pyrazole derivatives using as heat stabilizers of high-pressure polyethylene (LDPE): 1-acetyl-4-methyl-3(5)-(2-(3-nitrophenyl)vinyl)-1H-pyrazole (additive 1) and 4benzoyl-3-(2-(4-nitrophenyl)vinyl-5-phenyl-1-tosyl-1H-pyrazole (additive 2)) has been studied. It is established that the introduction of additive 1 or 2 in the amount of 0,05-0,10 wt % to the high-pressure polyethylene leads to the increasing of such physical-mechanical properties of the samples as tensile strength by 1,2–1,5 times and elongation by 2,3–3,0 times in comparison with the unstabilized sample. Synthesized substances are more effective than Tioalkofen MBP used in industry

Impact and process assessment of the seven CITYLAB implementations

CITYLAB focuses on four axes that call for improvement and intervention: •Highly fragmented last-mile deliveries in city centres •Inefficient deliveries to large freight attractors and public administrations •Urban waste, return trips and recycling •Logistics sprawl Within these axes, the project supports seven implementations that are being tested, evaluated and rolled out. An implementation is defined as the process of preparing, testing and putting into practice a new service or a new way of operating or organising logistics activities. The objective of this report is to present an assessment of the effects and consequences of the implementations as they are conducted. For each case, we summarise the process leading to the application of a specific technical and managerial solution, and present the outcomes. For each implementation, we present •Problem and aim •Description of the solution •Implementation process •Effects and consequences •Challenges ahead •Lessons and generalisation of results This deliverable provides a complete picture of the evolvement of the implementations during the CITYLAB project and final versions of the process and impact assessment

Sustainability analysis of the CITYLAB solutions

The objective of the CITYLAB project is to develop knowledge and solutions that result in roll-out, upscaling and further uptake of cost effective strategies, measures and tools for emission free city logistics. CITYLAB includes a set of Living Laboratories where promising logistic concepts are implemented related to emissions free city logistics. The objective of this report is to assess the impact that would occur when the CITYLAB implementations would be scaled up. The main challenge that has to be overcome is the difference in type, availability and detail of data from different CITYLAB implementations. This assessment of the impacts of upscaling is done by integrating all stakeholders’ opinions in the evaluation process and taking into account the costs and benefits for society as well as the financial viability for industry partners
