\u3ci\u3eTriepeolus Mesillae\u3c/i\u3e (Hymenoptera: Apoidea) in Illinois: A Cleptoparasitic Bee New to the Eastern United States

(excerpt) Cockerell (Ann. Mag. Nat. Hist., Ser. 7, 13:33-42,1904) named Triepeolus mesillae on the basis of a series of specimens which he collected at Mesilla, New Mexico. A second locality for the species was added by Rozen (Amer. Mus. Novitates 2244, 1966) when he described the larva of T. mesillae from cells of Nomia (Epinomia) triangulifera Vacha! excavated by E. A

Toepassingsmogelijkheden van Modified Atmosphere Packaging (MAP) in rozen en sierheesters

Boomkwekerijgewassen, zoals rozen en siergewassen, zijn in diverse stadia van de keten gevoelig voor kwaliteitsverlies. Dit kan uitdroging zijn door vochttekort, verrotting bij vochtovermaat of ongewenst uitlopen van het product. Uit eerder onderzoek is gebleken dat toepassing van zogenaamde Modified Atmosphere folies (MA, zie kader) al dan niet in combinatie met bepaalde vulmiddelen dergelijke problemen sterk kan verminderen en daarmee de houdbaarheid van producten kan verlengen. Dit rapport geeft de resultaten van een onderzoek naar de mogelijkheden van toepassing van MA-folie bij bewaring van rozen en siergewassen in verschillende delen van de keten

On the gravitational field of static and stationary axial symmetric bodies with multi-polar structure

We give a physical interpretation to the multi-polar Erez-Rozen-Quevedo solution of the Einstein Equations in terms of bars. We find that each multi-pole correspond to the Newtonian potential of a bar with linear density proportional to a Legendre Polynomial. We use this fact to find an integral representation of the $\gamma$ function. These integral representations are used in the context of the inverse scattering method to find solutions associated to one or more rotating bodies each one with their own multi-polar structure.Comment: To be published in Classical and Quantum Gravit

On a Puzzle About Experts, Screening-Off and the Rarity of Defeat

We introduce a ``rarity of defeat'' principle, valid in cases of deference to an expert, to address intuitions involved in a puzzle of Nissan-Rozen concerning epistemic deference and evidential screening-off

Натан Розен в Україні: невідомі сторінки життя та діяльності

Розглянута діяльність всесвітньо відомого фізика Натана Розена, що деякий час працював у складі Інституту фізики Академії наук УРСР (Київ). Базуючись на архівних матеріалах, розкриті невідомі сторінки життя вченого в Україні, та обставини за якими він потрапив у СРСР. Проаналізовано також статті Н. Розена, що вийшли друком у цей час в українських журналах.Activity of known worldwide physicist Nathan Rozen, which some time worked in structure of Institute of physics of Academy of sciences of Ukraine (Kiev) is considered. Based on the archived materials the unknown pages of life of scientist in Ukraine are illustrated. The scientific articles of N. Rozen. printed at this time in the Ukrainian magazines are analysed also

Voorstel aanpassing bemestingsadvies voor stikstof van rozen

Op 1 januari 2006 is de nieuwe mestwetgeving van kracht geworden met daarin o.a. stikstof (N)9gebruiksnormen. De N9gebruiksnormen zijn gebaseerd op de bestaande bemestingsadviezen. In de boomkwekerij sector hebben de kwekers van rozen aangegeven dat de normen voor stikstof te laag zijn. Een belangrijke reden hiervoor is dat sinds de totstandkoming van het bestaande bemestingsadvies de teelt is geïntensiveerd. Op basis van gegevens uit de literatuur, praktijk en eigen onderzoek is volgens de richtlijnen van het hiervoor beschikbare protocol een verzoek voor een voorlopig nieuw bemestingsadvies voor stikstof voor de rozen opgestel

Nest architecture of Oxaea austera (Andrenidae, Oxaeinae) and its significance for the interpretation of Uruguayan fossil bee cells

Oxaea austera nests in hard, red lateritic soils with dense grass cover. Some characters of Oxaea austera nests conform to the known architecture of the oxaeine nests such as the long, vertical shaft and the radiating, horizontal tunnels connected to vertical cells. The presence of more than one cell per lateral, cells at different depths containing larvae at different stages, and discrete walls in the main and laterals are described for the first time for Oxaeinae. One cell was located at the end of each lateral with others (2–4) near them, in some cases arranged in a row just beneath the lateral. Cells are oriented vertically and consist of a chamber, a spiral closure and an antechamber connected with a lateral. The chamber and antechamber are surrounded by a thick discrete wall. Each nest was occupied by at least two active females indicating communal nesting. They also contained older cells, suggesting the reutilization of the nests by successive generations. Both behaviors may be a response to the difficulties of excavation in hard soils. Communal nesting may be also a defensive behavior against nest cleptoparasites. The shape, size, discrete walls of lateritic soil material, spiral closure, and antechamber of O. austera cells closely resemble the fossil bee cells included in the ichnogenus Palmiraichnus from the early Eocene Asencio Formation of Uruguay. This new evidence reinforces the proposal of extinct representatives of Oxaeinae as it constructor.Fil: Sarzetti, Laura Cristina. Consejo Nacional de Investigaciones Científicas y Técnicas.
