To measure farmed foxes’ motivations for full, naturalistic social contact, we constructed an apparatus where they could perform an operant to access stimuli, but then leave freely and thence determine their own bout lengths. Motivational measures based on demand curves can be invalid in such set-ups, and we therefore sought to validate the measure ‘maximum price paid’. This was achieved by mea...

Particulate matter contamination is known to become wet and therefore ionically conductive and corrosive if the humidity in the environment rises above the deliquescence relative humidity (DRH) of the particulate matter. In wet condition, particulate matter can electrically bridge closely spaced features on printed circuit boards (PCBs), leading to their electrical failure. Failures attributed ...

P granules are non-membrane bound organelles that can be observed in the germline cytoplasm throughout C. elegans development. Like their ‘germ granule’ counterparts in other animals, P granules are thought to act as determinants of the identity and special properties of germ cells, properties which include the unique ability to give rise to all tissues of future generations of an organism. The...

As the building blocks of chromatin, histones need to be synthesized efficiently and synchronously with DNA replication. The mRNAs encoding the core histones undergo a distinct 30-end formation pathway that results in mature mRNAs ending in a stem loop instead of a polyadenylated tail. Considering that the factors involved in histone 30-end processing are well conserved across Eukarya, the abse...

Catalytic conversion of harmful gases produced in fossil-fuel combustion or in large-scale chemical transformations, such as CO or the oxides of nitrogen into nitrogen and carbon dioxide, is of utmost importance both environmentally and economically. For example, N2O is a potent greenhouse gas with a warming potential exceeding that of CO2 by a factor of 300, and its role in the depletion of st...

In der Oberflächenfiltration sind die Einflüsse Prozessbedingungen auf abgeschiedenen Partikeln von großer Bedeutung. Dazu gehören z. B. Temperatur und Zusammensetzung des Trägergases. Zwei unterschiedliche Erscheinungsformen Wasser im Trägergas ihre Auswirkungen lösliche Bestandteile Filterkuchen werden gegenübergestellt. diesem ersten Teil einer zweiteiligen Arbeit zunächst Grundlagen Erkennt...

The iNEMI technical subcommittee on creep corrosion is developing a flowers-of-sulfur (FOS) based qualification test for creep corrosion on printed-circuit boards (PCBs). The test setup consists of a 300-mm cube chamber with two means of mounting the test specimens and flowing air over them to expose them to constant, predefined humidity and temperature conditions and sulfur and other contamina...

We reconsider the consistency constraints on a free massless symmetric rank 2 tensor field in a background and confirm that they uniquely require it to be the linear deviation about (cosmological) Einstein gravity. Neither adding non-minimal higher derivative terms nor changing the gauge transformations by allowing terms non-analytic in the cosmological constant alters this fact. PACS numbers: ...

Es wird ein erhöhter Wassergehalt im Trägergas in der Oberflächenfiltration und dessen Einfluss auf lösliche unlösliche Partikeln Filterkuchen untersucht. Der erste Teil beschrieb die gemeinsamen Grundlagen den Stand des Wissens. Die Beeinflussung von Haftkräften mögliche Stofftransport Partikelmaterial gelöster ungelöster Form wurden als Auswirkungen eines erhöhten Wassergehalts diskutiert. zw...

and Applied Analysis 3 host population is described by the following system of equations: dSh dt = Λ h − bβhShIv Nh − μhSh, dIh dt = bβhShIv Nh + σbβhRhIv Nh − (γh + δh + μh) Ih, dRh dt = γhIh − σbβhRhIv Nh − μhRh, dSv dt = Λ v − bβvSvIh Nh − μvSv, dIv dt = bβvSvIh Nh − μvIv. (1) The total humans host and mosquitoes vector populations Nh = Sh+Ih+Rh andNv = Sv+Iv are governed, respectively, by d...
