The active micro-perforated panel absorber has excellent low frequency sound absorption performance, which is expected to realize low-frequency noise reduction in large space of the cabin. Since its performance depends on incident field environment, basis existing research conclusions duct, large-sized under excitation a normal plane wave typical free environment depth investigated. First, theo...

Frozen microtitration trays manufactured by Micro-Media Systems (MMS) for antimicrobial testing of anaerobic bacteria were evaluated and compared with the broth disk elution method of Virginia Polytechnic Institute (VPI) described by Wilkins and Thiel. A total of 224 clinical anaerobic isolates were tested. Susceptibility results were compared for carbenicillin, cefoxitin, chloramphenicol, clin...

This paper analyzes the relationship between factor substitutability and the energy intensity of manufacturing firms. Specifically, we compare the degree of substitutability between the input factors capital, labor, energy, and material for firms with low, medium, and high energy cost shares using a panel of Swiss manufacturing companies covering the period from 1997 to 2008. Our findings indic...

A micro-meso-macro analysis framework based on the multi-scale method was employed to analyse mechanical behaviour of marine GFRP stiffened panels. The study aims establish a procedure for assessing impact material composition and weave ultimate strength assessment an essential step in design process, investigation construction materials has great benefit lightweight composite structures. micro...

Abstract Spatially disaggregated income indicators are typically estimated by using model-based methods that assume access to auxiliary information from population micro-data. In many countries like Germany and the UK micro-data not publicly available. this work we propose small area methodology when only aggregate population-level is We use data-driven transformations of response satisfy param...

This paper presents a grid-tie rotating solar rooftop system power project which is powered by using Atmega 328 microcontroller. It includes panel, LCD display, and battery charging circuit an inverter with sun tracking capability. represents whether particular industrial or residential load would be the photovoltaic panel company. based on micro-controller controls array it consistently positi...

Poland’s imminent entry into the EU re-emphasises the long-standing need for the restructuring of the country’s agricultural sector and the associated re-allocation of its bloated workforce. The transition matrix of net flows derived from an annual panel of micro-data taken from the LFS confirms the impression of the stagnation that is conveyed by gross movements that are computable from the pu...

We propose a micro-econometric evaluation of the relation between life satisfaction and income distribution, using a balanced panel survey of the Russian population (RLMS), running from 1994 to 2000, covering 4685 individuals. We show that in the context of the very volatile Russian environment, Hirschman’s (1973) “tunnel effect” conjecture seems to be confirmed: variables reflecting income dis...

We investigate how multinational companies can foster economic development of the host country at the micro level. Traditionally the empirical literature measuring spillovers to the host economy arising from foreign direct investment has focused on productivity spillovers, i.e., technological externalities. In this paper we emphasise that pecuniary externalities from multinationals can also be ...

This paper revisits Verdoorn’s Law and issues related to its estimation using micro-data. Using a large panel of firms from the Brazilian manufacturing industry from 1996 to 2002, the exercise finds compelling evidence of increasing returns to scale in such a low level of aggregation using different specifications. The results were strengthened by indicator variables for sub-sectors and partici...
