The exploitation of nonlinear behavior in vibration-based energy harvesters has received much attention over the last decade. One key motivation is that the presence of nonlinearities can potentially increase the bandwidth over which the excitation is amplified and therefore the efficiency of the device. In the literature, references to resonating energy harvesters featuring nonlinear oscillato...

Since the introduction of the nanonetworks, molecular communication has become a popular research area in computer science. Although there are several methods proposed to implement molecular communication, none of them treats resources as discrete entities. We define resources as the discrete physical particles taking part in the communication tasks in a nanonetwork, such as information encodin...

The paper contributes to the topic of optimal utilization of spatially distributed renewable resources. Namely, a problem of “sustainable” optimal cyclic exploitation of a renewable resource with logistic law of recovery is investigated. The resource is distributed on a circle and is collected by a single harvester moving along the circle. The recovering and harvesting rates are position-depend...

that a shockload of 45 kW should be allowed. The desien of The development of a simple chopper harvester is described and ways in which this complicated machine might be simplified are suggested. The decisions taken and some of the specially designed components used in 'building the machine are described and the difficulties experienced during its operation and their solution are explained.

the aim of this study was to determine changes in the concentration of leptin and thyroid hormone in energyrestricted ewes and effect of leptin injection on thyroid hormone level. in the first experiment, 28 ewes were assigned to two groups(n=14). ewes were fed by a ration that provided 60% or 100% of maintenance energy requirements during 71 days. blood samples were collected and body weight(b...

A marked increase in the number of basophilic cells (BCs) was found in the bronchoalveolar lavage (BAL) fluids from the patients with bronchial asthma and idiopathic pulmonary fibrosis (IPF). Histochemical analysis revealed that basophils were the major components of BCs in asthmatic patients, while formalin-insensitive BCs, which are presumed to be connective tissue mast cells, were observed i...

Background and study aims Bile cast syndrome (BCS) is a complication of orthotopic liver transplantation (OLT). It occurs in 4 % to 18 % of OLT recipients and can present as cholangitis and graft damage or loss. Twenty-two percent of patients with BCS require repeat OLT. The diagnosis and management of BCS can be challenging. Our aim is to share our experience with BCS and to briefly review the...

This paper reports a microfabricated piezoelectric MEMS inertial energy harvester that can scavenge high-frequency mechanical vibrations in all three dimensions with an active inner volume of only 55 mm. The device can generate 0.1 to 10.5 μW from out-of-plane vibrations (365-465 Hz), and 0.1 to 3.2 μW from in-plane vibrations (680-930 Hz) at 0.5 g acceleration input. The reported harvester is ...
