Abstract (sommario):

Purpose – There has been growing interest in studying the internationalisation of small and medium-sized high-technology firms. This literature tends to equate “internationalisation” with the “internationalisation of sales”. Yet sales are not the only international activity of high-tech firms. High-tech firms need resources and not just markets. The purpose of this paper is to contribute to an understanding of this resource dimension of the international behaviour of high-tech firms. Design/methodology/approach – The empirical basis for the study lies in a multiple case study of six high-tech small and medium-sized enterprises (SMEs). The authors selected two firms from each of three high-tech industries: biotechnology (specifically drug development), renewable energy and ICT. The key decision makers in each firms were then interviewed in depth. Findings – The authors show that for the case firms in the study, internationalisation can take the form of searching, prospecting or “scavenging” for resources. “Resource-seeking” behaviour occurs because the SMEs do not own, control or have access to sufficient resources to bring their technology to market on their own. The pattern of internationalisation that results from resource scavenging is different to that of traditional “market-seeking” internationalisation. Originality/value – This paper provides evidence of how the resource-acquisition behaviour of high-tech SMEs can be an important element of their internationalisation. Yet existing literature has focused almost exclusively on the market-seeking internationalisation of these firms.

Abstract (sommario):

To determine the effect of different harvesting time on antioxidant capacity in Jerusalem artichoke polysaccharides (inulin), the Jerusalem artichoke before and after overwintering were collected from the same region, and then evaluate their antioxidant capacity in vitro by reducing power assay, DPPH radical-scavenging assay and hydroxyl radical-scavenging assay. Ascorbic acid at similar mass concentration was served as positive control. The results showed no significant difference were observed in reducing power when the absorbance values were about 0.3. When the mass concentrations before and after overwintering were 0.9 mg/mL and 1.7 mg/mL, the DPPH radical-scavenging rate both reached at 50%. And when the mass concentrations were both 10 mg/mL, the hydroxyl radical-scavengings were 35.8% and 27.9%, respectively. Thus, it could be concluded that the antioxidant capacity in Jerusalem artichoke polysaccharides before overwintering was higher than that after overwintering, and showed a good dose-dependent manner with its mass concentration.

Abstract (sommario):

Scavenging is the consumption of carrion by living organisms. Often overlooked, it is common in all ecosystems. The assemblage of scavengers that act on carrion are important in maintaining this ecosystem service and are part of the necrobiome. Scavengers can be classified into distinct guilds comprised of vertebrates, invertebrates, and microorganisms whose collaborative roles operate efficiently when their community structure is diverse and intact. The goal of this thesis is to quantify how scavenger guilds can influence decay rates and how insect scavengers respond to the absence of competition from vertebrate scavengers. Individually, the functional roles vertebrate and insect scavengers are known, but there is limited understanding about how their interactions influence decay rates. Changes in the composition of vertebrate and insect scavenger communities around carrion may prolong carcass persistence possibly altering the localised effects of nutrient flow and increase the chance of carcass borne disease spread. This is important in Kosciuszko National Park where land managers cull both large herbivores and facultative vertebrate scavengers possibly creating and influx of carrion and altering the functionality of the vertebrate scavenger guild. Using exclusion cages, this study was able to limit access from vertebrate and insect scavengers to compare decay rates of carrion in the presence and absence of each guild. In contrast to similar systems, utilisation of carcasses by vertebrates did little to influence decay rates. This was pronounced in autumn and winter when carcasses persisted the longest despite elevated vertebrate activity and reduced competition from insects and microbes. This shifts the function of carrion removal towards insects as vertebrates contribute little to decomposition leading to a reduction of resiliency of this process. How each guild interacted and operated in the other’s absence had profound effects on carcass persistence.

Mestrado em Ciência e Engenharia de Materiais
Gadolinium-doped ceria based powders were co-fired with additions of silica, and silica and lanthanum oxide, to test the silicascavenging role of lanthanum. The formation of one ionic conducting secondary phase, instead of an insulating phase, was attempted. The structural, microstructural and electrical characterization of these samples confirmed the formation of one apatite-type lanthanum silicate-based phase and a significant enhancement of the grain boundary conductivity of these materials. ABSTRACT: Pós de céria dopada com gadolínio foram sinterizados com adições de sílica, e de sílica e óxido de lantânio, para testar o efeito de remoção de sílica do óxido de lantânio. Com esta abordagem explorou-se a formação de uma fase secundária condutora iónica em vez de uma fase isoladora. A caracterização estrutural, microestrutural e eléctrica das amostras confirmou a formação de uma fase tipo apatite derivada do silicato de lantânio e uma melhoria significativa da condutividade da fronteira de grão destes materiais.

Abstract (sommario):

The aerosol removal has a fundamental role because aerosol has impact on human health, on visibility and act as a condensation center for cloud droplets and ice crystals, changing cloud properties (indirect e�ects on cli- mate). In this work, di�erent removal processes of aerosol have been studies experimentally (thermophoresis, ice nuclei, cloud condensation nuclei and below-cloud scavenging), with the aim to obtain a global study of these processes. Concerning the study of thermophoresis, experiments were per- formed in microgravity conditions, in order to minimize the impact of grav- ity. Particle trajectories and consequently particle velocities were recon- structed by analyzing the sequence of particle positions. Studies on forma- tion of IN and CCN, realized through two experimental campaigns, permit- ted to improve knowledge about these phenomena. Measurements related to CCN reveal diurnal trend with lower values at about midday and higher ones during the night. Measurements of IN reveal a positive correlation between higher supersaturation with respect to ice and water values and ice nuclei number concentration. Finally, indoor and outdoor measurements of aerosol concentrations were carried out; it was found that the aerosol removal is in uenced by rainfall duration.

Abstract (sommario):

In recent years, there has been recent increase in the deployment of wireless sensor networks. These sensors are typically powered by a battery which has limited life span. This problem can be overcomed by using energy scavenging or power harvesting which is the process of converting ambient energy from the environment into usable electrical energy. It can be used in applications such as remote patient monitoring, implantable sensors, machinery/equipment monitoring and so on. The thesis presents the RF scavenging system and mainly focuses on the study of the rectifier architectures which is one of the key components in the RF scavenging system. The thesis also provides the design challenges while implementing the different rectifier structures, which are PMOS bridge rectifier, CMOS differential rectifier and charge pump. The functionality of the rectifier structures are studied by simulation using RF signal of 900 MHz and implemented in 0.35μm and 65 nm technologies to compare the results. The simulation results shows that there is a tradeoff between high output DC voltage and high power efficiency. Maximum DC output voltage of 1 V is obtained from input amplitude level of 0.16 V using 7-stage charge pump rectifier. In the other hand maximum power efficiency of 23 % is obtained using CMOS differential rectifier.

Abstract (sommario):

This paper presents an ongoing body of work that aims to disrupt prevailing Modernist tendencies within computational design practices and digital design methodologies as well as present an alternative for archaic and highly standardized modes of sustainable design production through describing the development of a painterly attitude towards digital and material computation and its resultant workflow. This ongoing body of work looks at the radical shift from the linear in late Renaissance to the painterly in the Baroque and its potential within the context of contemporary computational design methodologies and digital fabrication. The paper presents a workflow that includes scavenging for natural material, 3D scanning, along with digital and material assembly in the form of reciprocal frame systems.

Testo completo

Abstract (sommario):

We suggest a model of rain scavenging of soluble gaseous pollutants in the atmosphere. It is shown that below-cloud gas scavenging is determined by non-stationary convective diffusion equation with the effective Peclet number. The obtained equation was analyzed numerically in the case of log-normal droplet size distribution. Calculations of scavenging coefficient and the rates of precipitation scavenging are performed for wet removal of ammonia (NH3) and sulfur dioxide (SO2) from the atmosphere. It is shown that scavenging coefficient is non-stationary and height-dependent. It is found also that the scavenging coefficient strongly depends on initial concentration distribution of soluble gaseous pollutants in the atmosphere. It is shown that in the case of linear distribution of the initial concentration of gaseous pollutants whereby the initial concentration of gaseous pollutants decreases with altitude, the scavenging coefficient increases with height in the beginning of rainfall. At the later stage of the rain scavenging coefficient decreases with height in the upper below-cloud layers of the atmosphere.
