The Multiple Temporalities of a Burial Monument: The Tumulus at Hrib

Tumuli are often analyzed as a coherent whole in the hope of discerning patterns that indicate social processes inhered in the monument. However, in the search for patterning too often the mound is analytically flattened, and examined as if it was created all at once with a coherent plan. In the following, I will focus on the tumulus at Hrib, an Iron Age tumulus in the Bela krajina region of Slovenia, and undertake a multiscalar analysis that considers temporal distinctions, interment ritual, grave goods, and gender to draw more nuanced conclusions about the social activities that led to the formation of this tumulus. The first level of analysis is the scale of individual ritual, where choices about how to appropriately dispose of and adorn the body are negotiated. Second is the social context of death and burial, which takes place at an intra-generational scale – that is, how death may resonate with the living community, and how the social relations of the living are affected by death. The final scale is the consideration of the tumulus as a whole at a multi-generational scale, and how cemeteries are places with continuous social impact, even when distinct memories of those interred have faded. This shift in the scale of analysis of the tumulus at Hrib illuminates that social distinctions were marked according to an external/internal binary, where material culture and social practices, including grave goods and funerary ritual, expressed social differences internally, while the external appearance of the mound projected unity

Ženske, ovce in tekstil: družbeni pomen jagod v obliki ovnove glavice v starejši železni dobi na Slovenskem

Ram’s head beads are well-known items of personal adornment in the Dolenjska Hallstatt cultural group. Recent analysis has demonstrated that they are the most common zoomorphic artefacts in this region with 187 currently known. This article updates the list of known beads and contextualizes their significance in the Dolenjska Hallstatt cultural group. It is argued that the sheep imagery of these beads and their distribution in female graves is related to local textile production. It is proposed that beads signalled aspects of personal and economic identity for Dolenjska Hallstatt women related to the production of high-quality textiles. In addition, the distribution of these beads demonstrates Iron Age community networks on the western frontier of Dolenjska, and perhaps even reflects the movement of women between communities.Jagode v obliki ovnove glavice sodijo med dobro znane nakitne predmete dolenjske halštatske kulturne skupine. S 187 doslej odkritimi primerki so na tem območju najpogostejše zoomorfne najdbe, kot je pokazala nedavna analiza. V prispevku je posodobljen seznam tovrstnih jagod in kontekstualiziran njihov pomen v tej kulturni skupini. Predstavljeni so argumenti za tezo, da so upodobitve ovac/ovnov v obliki jagod in njihovo pojavljanje v ženskih grobovih povezani z lokalno tekstilno dejavnostjo. Pripisati jim je mogoče vlogo označevalca osebne in ekonomske identitete dolenjskih halštatskodobnih žensk, povezano z izdelovanjem visokokakovostnih tkanin. Poleg tega kaže razprostranjenost teh jagod na mrežo tesnih stikov med najdišči na zahodnem obrobju teritorija dolenjske železnodobne skupnosti, morda odslikava celo mobilnost žensk med lokalnimi skupnostmi

Probable Displacement of Riffle-Dwelling Invertebrates by the Introduced Rusty Crayfish, \u3ci\u3eOrconectes Rusticus\u3c/i\u3e (Decapoda: Cambaridae) in a North-Central Wisconsin Stream

The rapid northward range expansion of the rusty crayfish, Orconectes rusticus, and its negative effects on Wisconsin lakes have been the subjects of intense study throughout the last fifteen years. In this study, we investigated the possible impact of rusty crayfish on the benthic macroinvertebrate community structure of the Prairie River in north-central Wisconsin. Rusty crayfish and other invertebrates were collected during August and September, 1994, from three sections of the Prairie River. Rusty crayfish relative abundance increased significantly from the upper to middle, and middle to lower sections; and correlated negatively with a significant 77% decrease in total density of aquatic invertebrates between sections. Mean density of all important invertebrate families and trophic guilds decreased significantly between the upper and lower sections. Due to the similarity of most environmental conditions between river sections, decrease of invertebrates is attributed to the increased abundance of rusty crayfish and its interactions with the native rouna. Our results suggest that a high abundance of rusty crayfish may negatively impact Wisconsin lotic systems

Insignia of power

Bird symbolism in the Dolenjska Hallstatt culture had strong associations with ritual and hierarchy, as demonstrated by bird imagery on insignia of power such as bronze vessels, wagons, and sceptres. The elaboration of such items with birds may have elevated items of prestige to items of ritual potency, highlighting the sacred and worldly power of the elite males with whom these items were associated. Avian depictions on bronze vessels, sceptres, and wagons with important cosmological and ritual associations indicate that birds were deeply entangled in presentations of status, particularly those that blurred the lines between the secular and sacred realms

Влияние моделей обратного тока насыщения диода на выходные характеристики двух-диодной модели солнечной батареи в среде Matlab Simulink

В работе проводилось моделирование солнечной батареи в программном обеспечении MATLAB Simulink. Изучались выходные параметры солнечной батареи в зависимости от модели обратного тока насыщения диода.

The output parameters of the solar battery were studied depending on the model of the reverse current saturation of the diode. The results are current-voltage and voltage-watt characteristics, showing the influence of the model of the inverse diode saturation current on the output parameters of the solar battery

C-Jun N-terminal kinase (JNK) isoforms play differing roles in otitis media

BACKGROUND: Innate immunity and tissue proliferation play important roles in otitis media (OM), the most common disease of childhood. CJUN terminal kinase (JNK) is potentially involved in both processes. RESULTS: Genes involved in both innate immune and growth factor activation of JNK are upregulated during OM, while expression of both positive and negative JNK regulatory genes is altered. When compared to wildtypes (WTs), C57BL/6 mice deficient in JNK1 exhibit enhanced mucosal thickening, with delayed recovery, enhanced neutrophil recruitment early in OM, and delayed bacterial clearance. In contrast, JNK2(−/−) mice exhibit delayed mucosal hyperplasia that eventually exceeds that of WTs and is slow to recover, delayed recruitment of neutrophils, and failure of bacterial clearance. CONCLUSIONS: The results suggest that JNK1 and JNK2 play primarily opposing roles in mucosal hyperplasia and neutrophil recruitment early in OM. However, both isoforms are required for the normal resolution of middle ear infection.
