Acoustic wave propagation in ultrasonic flow measurements is typically assumed to be linear and reciprocal.However, if the transmitting transducer generates a sufficiently high pressure, nonlinear wave propagation effects become significant. In flow measurements, this would translate into more information to estimate the flow and therefore a...

The obesity epidemic increases the interest to elucidate impact of short‐chain fatty acids on metabolism, obesity, and the brain. We investigated the effects of propionic acid (PA) and caproic acid (CA) on metabolic risk factors, liver and adipose tissue pathology, brain function, structure (by MRI), and gene expression, during obesity...

Current ultrasonic clamp-on flow meters are manually calibrated. This process is based on manual placement of two single-element transducers along a pipe wall. Due to the usually unknown pipe properties and inhomogeneities in the pipe geometry, the axial distance of the transducers needs to be manually calibrated to align the location of the...

Future applications of ultrasonography in (bio-)medical imaging require ultrasound sensor matrices with small sensitive elements. Promising are opto-mechanical ultrasound sensors (OMUS) based on a silicon photonic ring resonator embedded in a silicon-dioxide acoustical membrane. This work presents new OMUS modelling: acousto-mechanical non...

The Southern North Sea Basin area, stretching from the UK to the Netherlands, has a rich hydrocarbon exploration and production history. The past, present and expected future hydrocarbon and geothermal exploration trends in this area are discussed for eight key lithostratigraphic intervals, ranging from the Lower Carboniferous to Cenozoic. In...

Background: Sex-specific differences play a role in metabolism, fat storage in adipose tissue, and brain structure. At juvenile age, brain function is susceptible to the effects of obesity; little is known about sex-specific differences in juvenile obesity. Therefore, this study examined sex-specific differences in adipose tissue and liver of...

Typically, ultrasonic flow meters assume linear wave propagation. Nevertheless, if the transducers of an ultrasonic flow sensor excite a pressure wave with a high amplitude, nonlinear wave propagation effects become significant. The appearance of higher harmonics increases the bandwidth of the received signal, which may potentially lead to a...

Understanding the shallow gas system is critical for assessing its potential as an energy source, for evaluating the possible hazard of shallow gas for drilling and wind farm locations and for evaluating the effect of gas emissions at the seabed on marine ecosystems and climate. This paper presents the key elements and processes of the microbial...

Transit-time ultrasonic flow meters are based on the fundamental idea that the flow is the only non-reciprocal effect between an upstream and downstream measurement. Non-identical transducers can be used in a reciprocal manner if the circuit is made reciprocal. In this paper we analyze the effect of driver- and readout electronics on the zero...

Non-hydrocarbons (H2S, CO2, N2) reduce the economic value of natural gas accumulations. This paper presents new approaches to evaluate the probability to encounter high amounts of non-hydrocarbons. These approaches were developed as one of the deliverables of a 2-year JIP project carried out by TNO from September 2014-July 2016. The newly...

The delivery van is the workhorse of both companies and the self-employed within the Dutch economy. And with good reason: it is a multifunctional and flexible mode of transport and compared to (smaller) trucks and cars it is allo cheap to buy and use. Moreover, a drivering license B is sufficient to drive a delivery van, which means that many...

This paper discusses the influence of hydraulic continuity of reservoirs and faults and the lack thereof on the occurrence of local pore fluid pressure conditions deviating from previously established regional trends. The hydrodynamic-based approaches will be illustrated with case studies from the Netherlands, in particular.

De bestelauto is hét werkpaard van bedrijven en zzp'ers in de Nederlandse economie. Niet zonder reden: het vervoermiddel is multifunctioneel en flexibel inzetbaar, en is in vergelijking met (kleinere) vrachtwagens en personenauto's ook nog goedkoop in aanschaf en praktisch in gebruik. Daarnaast volstaat een B-rijbewijs om een bestelauto te mogen...

There is a growing awareness in cities throughout the world that green and blue infrastructure can offer a wide range of ecosystem services to support a healthy urban environment. For example, landscape architects explore possibilities in their design of the urban landscape to use the potential of green elements for regulating air temperature,...

There is increasing interest in the exploitation of the deep subsurface of the Netherlands for purposes other than conventional oil and gas production, such as geothermal energy, shale gas exploitation and the disposal of radioactive waste, so for technical and environmental reasons it is important to understand the composition of the deep...
