The design and fabrication of a combined electrochemical-cantilever microfluidic system is described. A chip integrating cantilevers with electrodes into a microchannel is presented with the accompanying polymer flow cell. Issues such as electrical and fluid connections are addressed, electromechanical behavior in ionic solution is investigated, and two uses of the system are demonstrated. First,

The development of integrated pest management is hampered by lack of information on how insect pest abundances relate to yield losses, and how pests are affected by control measures. In this study, we develop integrated pest management tactics for Apion spp. weevils (Coleoptera: Brentidae) in seed production of red clover, Trifolium pratense L. We tested a method to forecast pest damage, quantifie

Intraductal neoplasms of the pancreas are classified as intraductal tubulopapillary neoplasms (ITPNs) and intraductal papillary mucinous neoplasm (IPMNs) in the current WHO classification. ITPN is a rare tumor and there are only a few cases of ITPN reported in the literature. We present the case of an otherwise healthy 42-year-old male, who presented with upper abdominal pain. He was subsequently

In this paper, we propose a method for estimating statistical periodicities in symbolic sequences. Different from other common approaches used for the estimation of periodicities of sequences of arbitrary, finite, symbol sets, that often map the symbolic sequence to a numerical representation, we here exploit a likelihood-based formulation in a sparse modeling framework to represent the periodic b

The expansion in the supply of energy services over the last couple of centuries has reduced the apparent importance of energy in economic growth despite energy being an essential production input. We demonstrate this by developing a simple extension of the Solow growth model, which we use to investigate 200 years of Swedish data. We find that the elasticity of substitution between a capital-labor

Erosion resulting from landslides is a serious problem in mountainous countries such as Nepal. To restore such sites it is essential to establish plant cover that protects the soil and reduces surface erosion. Mycorrhizal fungi growing in symbiosis with plants are essential in this respect because they improve both plant nutrient uptake and soil structure. We investigated the influence of organic

Floral scent is a very important trait in plant evolution. Currently, little is known about the inheritance of floral scent in cowpea (Vigna unguiculata L.) or changes that might have occurred during its domestication. Therefore, we analysed scent volatiles and molecular markers in a population of 159 F7 recombinant inbred lines derived from a cross of a domesticated blackeye cowpea cultivar, ‘524

This article theoretically analyses via scholarly literature the consequences of how the networked technology, the Internet is conceptualised. The Internet, as argued here, can be understood in many ways, in the sense that the digital environment is very much dependant on metaphors and conceptual loans to be spoken and thought of. This affects our behaviour and social norms and forms a number of l

The field of plant cell wall biology is constantly growing and consequently so is the need for more sensitive and specific probes for individual wall components. Xyloglucan is a key polysaccharide widely distributed in the plant kingdom in both structural and storage tissues that exist in both fucosylated and non-fucosylated variants. Presently, the only xyloglucan marker available is the monoclon

The startup of a chemical plate reactor is investigated. A hybrid startup control scheme is presented and a discussion is made on how hybrid transition points could be chosen to allow safe startup despite actuator limitations, process nonlinearities and model uncertainties. The event-driven startup improves the robustness to uncertainties and disturbances, since each part of the startup is associa

Pressurized liquid extractions were performed on eight sediments in order to investigate if a modified US EPA method (100 degrees C, 100 bar, n-heptane/acetone (1:1), 2 x 5 min) provided exhaustive extractions of polychlorinated biphenyls (PCBs) from sediment, and to study if the extractability of PCBs from the different sediments was affected by characteristics of the sediment. The recovery from

Aims: Differences in morphology in adult barn swallows were investigated using bone and feather measurements taken from birds from a northern (Danish) and a southern (Spanish) European population. Discriminant Function Analysis was used to help in discriminating the sex of individuals of both populations. Location: Badajoz (Spain) and Kraghede (Denmark). Methods: Two discriminant functions were ob

We present a fast algorithm for optimal alignment between two similar ordered trees with node labels. Let S and T be two such trees with S and T nodes, respectively. If there exists an optimal alignment between S and T which uses at most d blank symbols and d is known in advance, it can be constructed in O(n log n (.) (maxdeg)(3) (.) d(2)) time, where n = max{S, T} and maxdeg is the maximum degree
