The amounts of Na+, Mg2 +, K+, Ca2 +, C1-, SO42-, HCO3- and dust precipitated in rainfall and as dry fallout into continuously open collection funnels are reported for 59 centres throughout Western Australia. Ionic accessions for 1973 were in the following ranges; Na+, 2-98 kg ha-1; Mg2+, 0.3-15 kg ha-1; Ca2+, 0.8-35 kg ha-1; K+, 0.3-14 kg ha-1; SO42-, 2-57 kg ha-1; C1-, 2-180 kg ha-1; HCO3-, 1-105 kg ha-1. Chloride deposition at the coast is approximately an order of magnitude greater in the south-west of the state than in the north. In each region the amount of chloride precipitated exhibited the usual decrease with distance inland. There were regional differences in rainwater salt composition. Excess of ions over the amounts attributed to oceanic aerosols are explained by the locations of sampling centres relative to other source areas. Perth, the largest city, had the highest excess sulphur and above average values were obtained at the larger mining and country centres. Industry and domestic fires are the probable sources of this sulphur. Excesses of all ions from terrestrial sources were indicated at many inland centres, and were greatest in the zone of salt lakes and occluded drainage in the south-west.

In a prospective observational study 4485 patients from 46 clinical centres in 17 European countries were followed between April 1994 and November 1996. Information on AIDS-defining events (ADEs) were collected together with basic demographic data, treatment history and laboratory results. The centres were divided into four geographical regions (north, central, south-west and south-east) so that it was possible to identify any existing regional differences in ADEs. The regional differences that we observed included a higher risk of all forms of Mycobacterium tuberculosis infections (Tb) and wasting disease in the south-west and an increased risk of infections with the Mycobacterium avium complex (MAC) in the north. In Cox multivariable analyses, where north was used as the reference group, we observed hazard ratios of 6·87, 7·77, 2·29 and 0·16 (P<0·05 in all cases) for pulmonary Tb, extrapulmonary Tb, wasting disease and MAC respectively in the south-west. Pneumocystis carinii pneumonia (PCP) was less commonly diagnosed in the central region (RH=0·51, 95% CI 0·32–0·79, P=0·003) and most common in the south-east (RH=1·04, 95% CI 0·71–1·51, P=0·85). Comparisons with a similar ‘AIDS in Europe’ study that concentrated on the early phase of the epidemic reveal that most of the regional differences that were observed in the 1980s still persist in the mid-1990s.

The parasite, Nosema apis, was found to be widespread among feral populations of honey bees (Apis mellifera) in the south-west of Western Australia. The location, month of collection and whether the feral colony was enclosed in an object or exposed to the environment, all affected the presence and severity of infection. There was no significant difference in the probability of infection between managed and feral bees. However, when infected by N. apis, managed bees appeared to have a greater severity of the infection.

Abstract Background We aimed to document the impact of the coronavirus disease 2019 (COVID-19) pandemic on regions within a European country. Methods Parents arriving at two pediatric emergency departments (EDs) in North of Switzerland and two in South of Switzerland completed an online survey during the first peak of the pandemic (April–June 2020). They were asked to rate their concern about their children or themselves having COVID-19. Results A total of 662 respondents completed the survey. Parents in the South were significantly more exposed to someone tested positive for COVID-19 than in the North (13.9 and 4.7%, respectively; P <  0.001). Parents in the South were much more concerned than in the North that they (mean 4.61 and 3.32, respectively; P <  0.001) or their child (mean 4.79 and 3.17, respectively; P <  0.001) had COVID-19. Parents reported their children wore facemasks significantly more often in the South than in the North (71.5 and 23.5%, respectively; P <  0.001). Conclusion The COVID-19 pandemic resulted in significant regional differences among families arriving at EDs in Switzerland. Public health agencies should consider regional strategies, rather than country-wide guidelines, in future pandemics and for vaccination against COVID-19 for children.

Over the past 30 years in Western Australia (WA), there has been heated debate about the future use of the remaining karri and jarrah forests in the south-west of the State. This debate revolves around policy proposals from two social movements: one wants to preserve as much of the remaining old-growth forests as possible, and an opposing movement supports a continued

THE Carlingford-Barnave district falls within the boundaries of Sheet 71 of the Ordnance Survey of Ireland, and forms part of a broad promontory lying between Carlingford Lough on the north-east and Dundalk Bay on the south-west. The greater part of this promontory is made up of an igneous complex of Tertiary age which has invaded the Silurian slates and quartzites and the Carboniferous Limestone Series. This complex has not yet been investigated in detail, but for the purposes of the present paper certain references to it are necessary, and these are made below. The prevalence of hybrid-relations and contamination-effects between the basic and acid igneous rocks of the region is a very marked feature, and because of this it has been difficult at times to decide which types have been responsible for the various stages of the metamorphism.

In view of the importance of a pure milk supply, we considered that it might be of interest to examine chemically, microscopically, and bacteriologically, a number of specimens of milk coming into the Metropolis for which purpose we decided to select samples from the various counties, the milk of which is consigned to London. We found that milk so consigned comes from about twenty-six counties extending from Derby in the North, to Hampshire and Devonshire in the South and South-West, and from Hereford in the West, to Norfolk in the East.

The Cyclopean Terrace Building lies to the north-west of the Lion Gate on the northern end of the Panagia Ridge and faces almost due west across the valley of the Kephissos and modern main road from Corinth to Argos. It lies just below the 200 m. contour line, and one terrace below the houses excavated in 1950–51 by Dr. Papadimitriou and Mr. Petsas to the east at the same end of the ridge. The area contains a complex of buildings, both successive and contemporary, and in view of the discovery of structures both to the south-west and, by the Greek Archaeological Service, to the north-east it is likely that this whole slope was covered by a portion of the outer town of Mycenae. This report will deal only with the structure to which the name Cyclopean Terrace Building was originally given, the so-called ‘North Megaron’, supported by the heavy main terrace wall.The excavation of this structure was begun in 1923. The main terrace wall was cleared and two L.H. IIIC burials discovered in the top of the fill in the south room. In 1950 it was decided to attempt to clear this building entirely in an endeavour to find out its date and purpose. The clearing was not, however, substantially completed until the close of the 1953 excavation season, and this report presents the available evidence for the date as determined by the pottery found beneath the building; the purpose is still a matter for study, though various tentative conclusions can be put forward.

In 2012, in the village Davidovac situated in south Serbia, 9.5 km south-west from Vranje, archaeological investigations were conducted on the site Crkviste. The remains of the smaller bronze-age settlement were discovered, above which a late antique horizon was later formed. Apart from modest remains of a bronze-age house and pits, a late antique necropolis was also excavated, of which two vaulted tombs and nine graves were inspected during this campaign. During the excavation of the northern sector of the site Davidovac-Crkviste the north-eastern periphery of the necropolis is detected. Graves 1-3, 5 and 6 are situated on the north?eastern borderline of necropolis, while the position of the tombs and the remaining four graves (4, 7-9) in their vicinity point that the necropolis was further spreading to the west and to the south?west, occupying the mount on which the church of St. George and modern graveyard are situated nowadays. All graves are oriented in the direction SW-NE, with the deviance between 3? and 17?, in four cases toward the south and in seven cases toward the north, while the largest part of those deviations is between 3? and 8?. Few small finds from the layer above the graves can in some way enable the determination of their dating. Those are two roman coins, one from the reign of emperor Valens (364-378), as well as the fibula of the type Viminacium-Novae which is chronologically tied to a longer period from the middle of the 5th to the middle of the 6th century, although there are some geographically close analogies dated to the end of the 4th or the beginning of the 5th century. Analogies for the tombs from Davidovac can be found on numerous sites, like in Sirmium as well as in Macvanska Mitrovica, where they are dated to the 4th-5th century. Similar situation was detected in Viminacium, former capital of the roman province of Upper Moesia. In ancient Naissus, on the site of Jagodin Mala, simple rectangular tombs were distributed in rows, while the complex painted tombs with Christian motifs were also found and dated by the coins to the period from the 4th to the 6th century. Also, in Kolovrat near Prijepolje simple vaulted tombs with walled dromos were excavated. During the excavations on the nearby site Davidovac-Gradiste, 39 graves of type Mala Kopasnica-Sase dated to the 2nd-3rd century were found, as well as 67 cist graves, which were dated by the coins of Constantius II, jewellery and buckles to the second half of the 4th or the first half of the 5th century. Based on all above mentioned it can be concluded that during the period from the 2nd to the 6th century in this area existed a roman and late antique settlement and several necropolises, formed along an important ancient road Via militaris, traced at the length of over 130 m in the direction NE-SW. Data gained with the anthropological analyses of 10 skeletons from the site Davidovac-Crkviste don't give enough information for a conclusion about the paleo-demographical structure of the population that lived here during late antiquity. Important results about the paleo-pathological changes, which do not occur often on archaeological sites, as well as the clearer picture about this population in total, will be acquired after the osteological material from the site Davidovac-Gradiste is statistically analysed.

A series of smal! volcanic centres cut Ordovician turbidites of Formation A in the southem part of Johannes V. Jensen Land between Midtkap and Frigg Fjord (Map 2). Their general location and main rock types were described by Soper et al. (1980) and their nomenclature is adopted here for fig. 22 with the addition of the small pipe B2. A further small intrusion, south-west of Frigg Fjord, was described by Pedersen (1980). The centres lie 5-10 km south of, and parallel to, the important Harder Fjord fault zone (fig. 22) which traverses the southern part of the North Greenland fold belt and shows substantial downthrow to the south (Higgins et al., this report).

IN 1908, Ron's grandfather, Issac Gray, took up an uncleared block of land 15 km north of Frankland in the south-west of Western Australia (see Fig. 1, Hobbs 2003). During that time he ran a few cattle in the bush and clearing of the native woodlands of Wandoo (white gum) Eucalyptus wandoo, J arrah E. marginata and Marri (Redgum) E. calophylla was slow and tedious. Ron's parents took over the farm in 1947, and with the advent of the bulldozer, clearing of Watkin's property and surrounding district began in earnest during the 1950s. Clearing continued as fast "as money permitted", until almost the last natural vegetation was knocked down in 1978 (Fig. 1). Annual pastures with some cropping (for supplementary feed) were the main source of fodder for sheep and cattle.
