The aim of this study is to report the parasitoids collected on many substrates in the agroforestry area in Brazil. The experimental study was carried out in an agroforestry area in the south of Goiás, Brazil. Traps made of metal containers. They served as baits to attract flies: fish, bovine kidneys, human feces and chicken viscera deposited inside metal containers, on a layer of sand. This sand was sieved after the pupae were extracted and subsequently placed individually in small glass containers to obtain flies and parasitoids. From 745 pupae of dipteran collected 684 parasitoids emerged from 111 pupae. The most frequent species in this study was Aphaereta sp. (Hymenoptera: Braconidae: Alysiinae) 52.6%. The total percentage of parasitism obtained at work was 14.9%. Brachymeria podagrica Fabricius (Hymenoptera: Chalcididae) was the species that presented the highest percentage of parasitism with 55.0%, parasitizing Ophyra aenescens L. (Diptera: Muscidae) on human feces substrate

This paper presents the results of an experimental study on the behaviour of inclined groynes and a short discussion on the optimization of groyne systems It supplements a paper presented at the XI Coastal Engineering Conference (London, 1968) In the present paper both studies are applied to the design of a groyne system looated to the south of the Tagus estuary (near Lisbon)j where a serious erosion has been under way.

The pavement of this unit was of cocciopesto and the walls were covered with a high cocciopesto socle with upper parts in coarse plaster. A wooden stairway ascended from the south-west corner, along the west wall, and an L-shaped, red-painted masonry bench (h.: 760 mm; l.: 3.3 m; w.: 60 mm), inset with two small dolia, projected into the centre of the room from the south-east corner. In the west end of this bench Elia recorded a masonry fornello. Remains of the closing system, included an iron door key, were found in the east entrance. The presence of the key suggests that this establishment was abandoned in haste. On the pavement near the north jamb, an inscribed amphora was found. In the northeast corner, a small ceramic vase was found. Against the south wall stood a tripod on which were found the remains of another ceramic vessel. On the bench were found: a bronze funnel; four more ceramic vases; the base of a terra sigillata dish, possibly reused; a large glass storage jar; two small glass bottles; a bronze tube; a clay lamp; and two bronze coins, one Republican and one an as of Tiberius. These finds point to this area having been used for food preparation although this is less evident for the two small glass bottles. A bronze ring, possibly a finger-ring, and four more coins (Republican and Julio-Claudian) were found a few centimetres above the pavement. At 2.5 m above the pavement were found a bronze cooking pot, a bronze bucket, and a terra sigillata dish. These objects were conceivably from the upper storey, implying that cooking and eating may also have been taking place there, although these could have been disturbed from the ground floor. Elia identified this as a ‘taberna’ and Packer referred to it as ‘Caupona Poppaeorum’. The finds indicate that food was being prepared here. Packer believed that the owner had a small apartment above. If the finds from the upper levels of the volcanic deposit were from the upper floor, this would suggest that cooking activities were also being carried out there. However, this seems an unlikely activity in the residence of someone who ran a food outlet.

Abstract. This experimental study deals with the perception of regionally colored accents of Standard Dutch (from Groningen, Friesland, Limburg, Zuid-Holland, and West-Flanders) as compared to 'pure' Standard Dutch. Three different aspects were investigated: speech-based personality impression, perceived linguistic divergence, and geographic identifiability. Listeners originated from different parts of the Netherlands. As for personality impression, speakers of 'pure' Standard Dutch were perceived to be significantly more dominant (arrogant, self-assured, and active) than accented speakers from Groningen, Friesland, Limburg, and West-Flanders, and they received significantly higher ratings on the integrity dimension (reliable, fair, and education) than accented speakers from Limburg. No other significant differences (e.g. related to social attractiveness) were found. With respect to linguistic divergence, the speakers from the south (Limburg and West-Flanders) were perceived to have significantly stronger and more homogeneous accents than the speakers from the north (Groningen and Friesland) and the west (Zuid-Holland). Finally, the geographic origin of the speakers from Limburg appeared to be the easiest to identify and that of the speakers from West-Flanders and Groningen the most difficult.
