The Forum was the center of Roman life. It witnessed a barrage of building, destruction and reuse from the seventh century BCE onwards. By around 80 BCE, patrons chose to renovate the Senate House and Comitium with a fresh paving of tufa blocks. Masons leveled many ruined altars and memorials beneath the flooring. Yet paving also provided a means of saving some of Rome’s past. They isolated the Lapis Niger with black blocks, to keep the city’s sinking history in their present. Paving therefore became a technology of memory for recording past events and people. Yet how effective was the Lapis Niger as a memorial? Many modern scholars have romanced the site’s cultural continuity. However, in fifty years and after two Lapis Nigers, the Comitium had borne a disparity of monuments and functions. Rome’s historians could not agree on what lay beneath. Verrius Flaccus reports that the Lapis Niger ‘according to others’ might mark the site of Romulus’s apotheosis, his burial, the burial of his foster father Faustulus, or even his soldier, Hostius Hostilius (50.177). Nevertheless, modern archaeologists have found no tombs. Instead of trying to comprehend these legends, most scholars use them selectively to isolate a dictator, deity or date. We must instead understand why so many views of the Lapis Niger emerged in antiquity. Otherwise, like ancient antiquarians, we will re- identify sites without end. Recreating how these material and mental landscapes interacted and spawned new pasts tells us more about the Lapis Niger than any new attribution. / text

The permanent pasture based on a grass-clover association and utilised in situ by grazing stock is the basis of New Zealand's chief primary industries. Although white clover is the main legume species used for this purpose its production and persistence in the drier eastern areas of the South Island often leaves much to be desired. In such situations subterranean clover may provide a useful alternative. Subterranean clover has been a very useful species in the past and will probably continue to play an important role in the future, provided the most climatically adapted cultivars are grown. The aim of the field trials was to evaluate the productive performance of several subterranean clover cultivars in Canterbury. Because of the big influence of seed yield on subsequent production and persistence in annuals, this aspect was also investigated. The subterranean clover cultivars Geraldton, Yarloop, Woogenellup, Clare, Mt. Barker and Tallarook were evaluated under cutting in swards at two sites in Canterbury.

Optical parameters measured via absorption spectroscopy and high-resolution fluorescence spectroscopy were used to characterize dissolved organic matter (DOM) in the springshed of Kings Bay, a spring-fed estuary located on Florida's Springs Coast. Over the past 40 years, springs supplying groundwater to Kings Bay have shown an increase in nitrate concentration. The overall goal of this project was to fingerprint wells and spring sites with elevated nitrogen concentrations using CDOM optical properties and establish relationships between nutrient and optical parameters. Samples were obtained from various sites: springs, Kings Bay surface (KBS), wells, coastal waters in and at the mouth of Crystal River (Coast) and lakes and rivers (LNR), during dry and wet seasons. The relationships between the environmental parameters and traditional optical parameters which provide insight into source characteristics were analyzed. Excitation emission matrix spectroscopy (EEMS) provided information about the concentration and chemical nature of organic matter in the study area. CDOM optical properties combined with salinity clearly separated the sources of fixed nitrogen in the Bay. Northern springs with elevated dissolved inorganic nitrogen (DIN) concentration had lower salinities and showed a presence of protein peaks. CDOM concentration was negatively correlated with total nitrogen (TN) and DIN, which suggests that these are subjected to anthropogenic influences. Humic peaks dominated the composition of the southern springs. CDOM concentrations were much higher than in the northern springs and there was a positive correlation between CDOM and both TN and DIN. These findings suggest that the fixed nitrogen in the southern springs is naturally occurring organic matter and the low concentrations may partially be a result of subsurface mixing of saltwater and freshwater in the aquifer. Thus, hypothesis testing showed that there was a significant difference between northern and southern springs Hypothesis testing also showed that there is a significant and unexpected positive relationship between CDOM and salinity studying Kings Bay, which is due to the low CDOM concentration in the springs discharging fresh water. This unique dataset also determined that the intercept of the mixing line was significantly different form zero. This indicates that CDOM is present and detectable at very low concentrations. Parallel Factor Analysis (PARAFAC) was used to evaluate CDOM composition from excitation emission matrix spectra (EEMs) and five components were identified: two humic, two marine humic, and one protein-like. The marine-like components, peak M, were produced in the marine environment and in meteoric groundwater. The study found a unique groundwater marker for coastal regions. Northern Kings Bay sites were characterized by a protein-like component, which has been associated with wastewater. Additional optical and environmental parameters were used in discriminate analysis, which successfully identified the CDOM markers for both natural and anthropogenic sources of nutrients in the environment. It is vital to improve the analysis of water, nutrients, and carbon from groundwater discharge into the coastal zone. Elevated DIN concentrations in groundwater are a widespread problem in Florida and over the past 30 years many spring waters have shown an increase in DIN concentrations. Nutrient discharge into delicate coastal areas can lead to ecological concerns. Investigating CDOM and nutrient distribution together can be a beneficial tool that can help differentiate sources from riverine/lacustrine, estuarine, marine, groundwater, and sewage impacted categories.

É necessário, portanto, o monitoramento de diversos indicadores de qualidade e entre eles a avaliação de resíduos de agrotóxicos. O trabalho tem como objetivo estudar a qualidade da água subterrânea usada na irrigação para a produção de hortaliças localizada na Comunidade Várzea Comprida dos Oliveiras e Bezerro no Município de Pombal/PB, considerando seu uso para irrigação. Foi desenvolvido no município de Pombal/PB, por meio de visitas feitas nas comunidades Várzea Comprida dos Oliveiras e Bezerro que trabalham com a produção de hortaliças irrigadas com água subterrânea de poços tubulares na região, foram coletadas 19 amostras de água e analisadas in loco e encaminhada ao laboratório de análises de solo e água (IFPB/ Sousa). Houve uma redução da condutividade elétrica das águas a partir de fevereiro, período marcado pelo início das chuvas, demonstrando o efeito da água da chuva na diluição dos sais. O Rio Piranhas apresentou maiores valores de Turbidez a partir de Fevereiro, pois as chuvas nesse período conseguem revolver os materiais depositados no fundo do rio e arrastar os que estão no leito do rio. Dois sais foram estudados, o bicarbonato foi o íon que apresentou os maiores valores nas águas, com poços 4, 6 e 10 apresentando 11,3, 10,34 e 10,42 mmolc L-1. Cloreto e o Sódio apresentaram resultados variando de 0,4 a 2,7 mmolc L-1 e 0,2 e 3,68 mmolc L-1 respectivamente, não causando preocupação para o uso na irrigação, levando em consideração um manejo de irrigação eficiente. A relação adsorção de sódio apresentou os maiores valores nos poços 4 (2,67 mg L-1) e 13 (2,6 mg L-1). / The intensive agriculture developed has different environmental impacts on water quality. It is therefore necessary to monitor several quality indicators and including the assessment of pesticide residues. The work aims to study the quality of groundwater used for irrigation for vegetable production located in the Community of Lowland Long Calf Olives and the City of Pombal / PB, considering its use for irrigation. Was developed in the municipality of Pombal / PB, through visits in the communities of Long Lowland Olive Calf and working with the production of vegetables irrigated with groundwater from wells in the region, 19 water samples were collected and analyzed in situ and referred to the analysis of soil and water (IFPB / Sousa) laboratory. A reduction in the electrical conductivity of the water since February, a period marked by the onset of the rains, demonstrating the effect of rainwater dilution of salts. The Piranhas River showed higher turbidity from February, as rains in this period can revolve the materials deposited on the river bottom and drag those in the riverbed. Two salts were studied, bicarbonate ion was showed the highest values in water, wells 4, 6 and 10 showing 11.3, 10.34 and 10.42 mmol L-1. Sodium chloride and the presented results ranging from 0.4 to 2.7 mmol L-1 and 0.2 and 3.68 mmol L-1, respectively, causing no concern for use in irrigation, taking into account a management efficient irrigation . The sodium adsorption ratio showed the highest values in four wells (2.67 mg L-1) and 13 (2.6 mg L1).

This study consisted of two sheep grazed dryland pasture experiments. Experiment l compared sheep production from 3-year-old cocksfoot based pastures grown in combination with white, Caucasian, subterranean or balansa clover with a ryegrass-white clover pasture and a pure lucerne forage. Sheep liveweight gain per head from each pasture treatment and the pure lucerne stand was recorded in the 2006/07 and 2007/08 seasons. The cocksfoot-subterranean clover pasture provided equal (381 kg LW/ha in 2006) or higher (476 kg LW/ha in 2007) animal production in spring and gave the highest total animal production (646 kg LW/ha) averaged across years of the five grass based pastures. However, total annual liveweight production from lucerne was higher than any grass based pasture mainly due to superior animal production during summer when lucerne provided 42-85% higher animal production than any of the grass based pastures. In Experiment 2, the effect of stocking rate (8.3 (low) and 13.9 (high) ewes + twin lambs/ha) and time of closing in spring on lamb liveweight gain, pasture production and subterranean clover seedling populations was monitored over 2 years for a dryland cocksfoot-subterranean clover and ryegrass-subterranean clover pasture in Canterbury. In both years, twin lambs grew faster (g/head/d) in spring at low (327; 385) than high (253; 285) stocking rate but total liveweight gain/ha (kg/ha/d) was greater at high (7.26; 7.91) than low (5.43; 6.38) stocking rate. Ewes also gained 0.5 and 1.5 kg/head at the low stocking rate in 2006 and 2007 respectively but lost 0.2 kg/head in 2006 and gained 0.3 kg/head at high stocking rate in 2007. Mean subterranean clover seedling populations (per m²) measured in autumn after grazing treatments in the first spring were similar at both low (2850) and high (2500) stocking rate but declined with later closing dates in spring (3850, 2950, 2100 and 1700 at 2, 4, 6, 8 weeks after first visible flower). Seedling populations measured in autumn after grazing treatments in the second spring were also unaffected by stocking rate (low 1290, high 1190) but declined with later closing dates in spring (1470, 1320 and 940 at 3, 5 and 8 weeks after first flowering, respectively). The effect of stocking rate and closing dates in spring on pasture and clover production in the following autumn was similar to the effects on seedling numbers in both years. However, clover production in the following spring was unaffected by stocking rate or closing date in the previous year at the relatively high seedling populations generated by the treatments. This was presumably due to runner growth compensating for lower plant populations in pastures that were closed later in spring. Subterranean clover runner growth in spring may not compensate in a similar manner if seedling numbers in autumn fall below 500/m². Mean annual dry matter production from cocksfoot and ryegrass pastures grown with and without annual clovers pasture production ranged from 6.4 to 12.4 t DM/ha/y but stocking rate (8.3 vs. 13.9 ewes/ha) during spring did not affect annual pasture production. Pastures overdrilled with annual clovers yielded 23-45% more dry matter production than pastures grown without annual clovers. The study confirms the important role of subterranean clover in improving pasture production and liveweight gains of sheep in dryland cocksfoot and ryegrass pastures. Lowering stocking rate from 13.9 to 8.3 ewes/ha was a less effective method of increasing seed production of subterranean clover in dryland pastures although it did lead to increased liveweight gain per head.

<p>This case study explores how geo-political power structures influence and/or determine the conception, acceptance and maintenance of what is considered to be valid archaeological knowledge. The nature of this contingency is exemplified through an examination of how the prehistory of Norrland, a region traditionally considered and portrayed as peripheral vis-à-vis the centre-South, was interpreted and presented by Swedish archaeologists during the 20th century. This contextual situation is analysed through the implementation of three interrelated and complimentary perspectives;</p><p>1) The relationship between northern and southern Sweden is examined using concepts concerning the nature of colonialism, resulting in the formulation of 20 particulars that typify the colonial experience, circumstances that characterise the historical, and unequal, association that has existed between these two regions for the last 600 years.</p><p>2) Ideals of national identity and heritage as manufactured and employed by the kingdom and later by the nation-state, with the assistance of antiquarianism, archaeology and/or centralised cultural management, are outlined. The creation of these various concepts have reinforced and perpetuated the colonial and asymmetrical association between what has naturally come to be viewed as the peripheral-North and the centre-South.</p><p>3) A century of archaeological research into the Norrlandian past is studied using the concepts ‘thoughtstyle’ and ‘thought-collective’ as devised by Ludwik Fleck. This analysis disclosed a persistent set of reoccurring explanations that have constantly been invoked when interpreting and presenting the prehistory of Norrland. This archaeological thought-style has normalised the unbalanced power relationship between North and South that has existed for the last 600 years by projecting it far back into the prehistoric past.</p><p>This case study has demonstrated that archaeologists, unless acutely aware of the historical context in which they themselves move and work, risk legitimising debilitating economic and political power relationships in the present through their study and presentation of the past.</p>
