Two novel easy‐to‐make pheromone traps, a cross‐barrier sticky trap and an open horizontal sticky trap, are described. Both types caught about the same number of male pine sawflies, Neodiprion sertifer, when baited with the synthetic pheromone (2S, 3S, 7S)‐3,7‐dimethylpentadec‐2‐yl acetate. The catch on unbaited cross‐barrier traps was about 17% compared with baited traps, whereas unbaited horizon

The external differences between the well‐documented S. scolytus and the little studied S. laevis are clarified with the help of SEM micrographs of the frons and abdomen of both sexes of the two species. The convex frons of both male and female S. scolytus is densely covered with short hairs. S. laevis males have a flat frons with long hairs in a pair of bundles, whereas the females have a convex

Parents re-emerged sooner at higher densities but the total proportion that re-emerged was independent of density. Over 20 offspring per female were produced at the lowest density (0.5/100 cm2) but only 0.6 per female at the highest density (31/100 cm2). Offspring from the lowest density were about 50% heavier than those from the highest density and also the fat content increased with decreasing d

Lidar is a powerful technique normally associated with atmospheric monitoring. However, lidar techniques, also of the laser-induced fluorescence and laser-induced breakdown spectroscopy varieties, provide many new possibilities in unconventional fields including cultural heritage and ecological applications.

A difference in female pheromone production and male behavioral response has previously been found in two populations of the turnip moth, Agrotis segetum, originating from Sweden and Zimbabwe, respectively. In this study, we investigated the pheromone response of antennal lobe interneurons of males of the two populations by intracellular recordings, stimulating with single pheromone components and

Four compounds, tetradecyl acetate, (Z)‐9‐tetradecenyl acetate, (E)‐11‐tetradecenyl acetate and (Z)‐11‐tetradecenyl acetate were identified from female sex pheromone extracts of Hungarian and Egyptian lima‐bean pod borers (Etiella zinckenella Tr., Lepidoptera: Phycitidae) by gas chromatography with flame ionization (FID) and electroantennographic (EAD) detection. In EAG studies these monounsaturat

Heterogenous bimodal harmonic-structure (HS) materials are interesting because of excellent structural efficiency. In this work, we present a simple yet powerful analytical model allowing to evaluate strain partitioning between coarse- and ultrafine- grain (CG and UFG, respectively) structure components in HS materials and to estimate the magnitude of back-stress forming at their interphases. The

For a long time, married women were treated differently from married men in personal income tax acts (PITA’s) around the world. The Netherlands was no exception to this rule. The PITA reflected the political, religious and legal situation, but at the same time was often behind on developments in those areas. The current Dutch semi-individual tax system in which single earner families pay more tax

The network topology of a protein interactome is shaped by the function of each protein, making it a resource of functional knowledge in tissues and in single cells. Today, this resource is underused, as complete network topology characterization has proved difficult for large protein interactomes. We apply a matrix visualization and decoding approach to a physical protein interactome of a dendrit

There are two levels to this thesis, the examination of the particular case and the exposition of the general approach. The case the thesis deals with is Louisiana’s coastal land-loss crisis and what can and should be done about it. I examine the current approach to coastal protection and restoration in the state of Louisiana, drawing on different economic theories of sustainable development and c

OBJECTIVE: To assess pulmonary function and Chronic Obstructive Pulmonary Disease (COPD) development over time in patients with primary Sjögren's Syndrome (pSS) and the association between pulmonary function, radiographic findings, respiratory symptoms and clinical features of pSS, taking cigarette consumption into account.METHODS: Forty patients with pSS (mean age 66 yrs, range 42-81 yrs, 39 wome

Stratospheric aerosol has long been seen as a pure mixture of sulfuric acid and water. Recent measurements, however, found a considerable carbonaceous fraction extending at least 8 km into the stratosphere. This fraction affects the aerosol optical depth (AOD) and the radiative properties, and hence the radiative forcing and climate impact of the stratospheric aerosol. Here we present an investiga

Älska Skog educational competition (Gothenburg, Sweden)Gothenburg-based educational institute Universeum is running annual design competitions on forest topics for primary school pupils, starting in 2016. Based on various activities in which pupils gain knowledge about forest-related challenges and opportunities as well as forestry, they would design plans to deal with those problems. After a firs

Inspections, Structural Health Monitoring (SHM), and Damage Detection System (DDS) are integral parts of structural integrity management (SIM) to ensure the structural performance and the required safety. This paper describes novel approaches on how the outcomes of Structural Health Monitoring (SHM) can be modeled, predicted, and combined with inspection planning in the frame of pre-posterior deci

Artiklen sætter fokus på en nylig materiel vending i litteraturen; en ny opmærksomhed mod litteraturens materielle diensioner som præger både litteraturkritikken olitteraturen selv. Med udgangspunkt i litterære materialitetsteorier af bl.a. Bill Brown og N. Katherine Hayles undersøger jeg, hvordan denne tendens kommer til udtryk i to værker, Anne Carsons Nox og Oscar K.s Af Olafur Kjartanssons opt
