Published: August 2021

The most prominent obstacle facing the construction industry in Yemen is mismanagement. Developing appropriate tools, approaches, and standards for managing construction projects will contribute effectively to the development and prosperity of the Yemeni construction industry. This study aims to provide the tools, approaches and standards for project management based on the opinions of the Yemeni advisory bodies. It presents an Integrated Cost, Quality, Time, and Scope (ICQTS) diamond framework model by developing the traditional triangle model in project management providing a practical contribution to researchers and companies working in the construction industry. The study uses a descriptive and analytical approach through a comprehensive literature review followed by a field study using a designed questionnaire distributed to the relevant Yemeni advisory bodies. The study concluded with the development of the traditional triangle model resulting in the introduction of the diamond framework model in the management of construction projects. Integration management was found to have a strong impact on project success presenting the framework model as an easy and flexible tool that unifies and integrates the processes and roles in the project and directing it towards achieving project stakeholder objectives. The literature largely neglects the impact of integration management in the various models and is mostly overlooked. Inclusion of integration management in the presented model will highlight measures of project success stressing the need to integrate and manage them together. Future studies may research the differences in the opinions of construction companies.

Published: August 2021

Introduction

Every year, many people die due to cancer in all of the world. So, the preparation and formulation of new chemotherapeutic supplements and drugs with remarkable effects to treat cancer are a priority of both developing and developed countries. Recently, zinc nanoparticles have been used as modern chemotherapeutic drugs to treat several cancers such as leukemia, lung cancer, breast cancer, prostate cancer, etc. In this study, zinc nanoparticles (ZnNPs) were synthesized in an aqueous medium using Fumaria officinalis leaf as stabilizing and reducing agents.

Material and methods

The green synthesized ZnNPs@Fumaria officinalis were characterized using different techniques including UV-visible and FT-IR spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray spectrometry (EDS). The anticancer activity of ZnNPs@Fumaria officinalis was evaluated against acute myeloid leukemia and acute T cell leukemia. According to the XRD analysis, 20.44 nm was measured for the crystal size of ZnNPs@Fumaria officinalis.

Results

SEM images showed a uniform spherical morphology with an average size of 27.96 nm for ZnNPs@Fumaria officinalis. In the cellular and molecular part of the recent study, the cells treated with ZnNPs@Fumaria officinalis were assessed by MTT assay for 48 h regarding the cytotoxicity and anti-human acute leukemia properties on normal (HUVEC), acute myeloid leukemia (32D-FLT3-ITD and Human HL-60/vcr), and acute T cell leukemia (Jurkat, Clone E6-1 and J.RT3-T3.5) cell lines. In the antioxidant test, the IC50 values of ZnNPs@Fumaria officinalis and BHT against DPPH free radicals were 187 and 197 µg/ml, respectively. The IC50 values of ZnNPs@Fumaria officinalis were 227, 200, 250, and 336 µg/ml against 32D-FLT3-ITD, Human HL-60/vcr, Jurkat, Clone E6-1, and J.RT3-T3.5 cell lines, respectively. The viability of the malignant leukemia cell line decreased dose-dependently in the presence of ZnNPs@Fumaria officinalis.

Conclusions

It appears that the anti-human acute leukemia effect of ZnNPs@Fumaria officinalis is due to their antioxidant effects.

Objetos rituais em finados
Authors: Silva Andreia Vicente da
Published: August 2021

Neste ensaio visual o objetivo é sublinhar o papel fundamental dos objetos rituais no feriado de Finados. As fotografias foram obtidas a partir de trabalho de campo realizado em 2017, no Cemitério Municipal Cristo Rei em Toledo, no Paraná. Os objetos focalizados são principalmente as flores e as velas que têm relação direta com o cuidado dos mortos, seja adorno, seja intercessão, seja memória e podem ser visualizados nos momentos de cuidado da sepultura e de orações no cruzeiro.Ao caminhar pelo cemitério perseguindo os objetos, vi e ouvi muitas negociações e dúvidas dos enlutados a respeito da disposição de flores e velas. Por isto mesmo, aposto que dar mais atenção a presença e o uso dos objetos rituais pode nos levar a compreender certos consensos coletivos mínimos que são construídos no território do cemitério que embora seja um espaço público plural tem uma lógica cristã marcada. Os pontos centrais dos consensos giram em torno das etapas do ritual e fazem com que aqueles que vão a necrópole no feriado dialoguem num mesmo idioma de sentidos. Os objetos constroem e reforçam as relações entre vivos em mortos.A disposição dos objetos nos túmulos e no cruzeiro demonstram grande cuidado e atenção por parte dos enlutados. As flores cumprem um papel fundamental de adornar os túmulos com seu colorido e suas formas e os enlutados passam muitos minutos – algumas vezes horas – estudando minuciosamente a posição e a disposição para depositá-las. Já as velas se referem ao aspecto da intercessão. Nelas há que se ressaltar a essencialidade da chama,  tanto que muitos enlutados fazem uma grande engenharia para mantê-las acesas. Alguns túmulos já possuem suporte para a colocação das velas. Em outros casos, pedaços de tijolo, cerâmica, papelão e pau servem de abrigo. “Iluminar o caminho”, “ajudar a aplacar as angústias”, “ajudar na passagem para o outro mundo”. Estas foram algumas das justificativas que ouvi dos enlutados para a utilização da vela nos túmulos dos seus parentes.O fogo e as velas coletivas estão no cruzeiro. As chamas formadas por inúmeras delas se propagam com maior intensidade como extensão do rito comunitário. No cruzeiro o fogo e as preces constroem as labaredas e fumaça na qual os enlutados se inserem e ativamente intercedem pelas almas no purgatório num grande esforço comum. Outros objetos cristãos são depositados no cruzeiro e permanecem entre a fumaça e as chamas sendo aquecidos e queimados.Mais do que acessórios, os objetos rituais são centrais para a dinâmica e para o sucesso do ritual. Afinal, é a partir deles que os enlutados se organizam e é para depositá-los que se dirigem a necrópole todos os anos no “Dia dos Mortos”. Através dos objetos rituais é que finados se constrói.

Abstract. Strict seasonal emission controls are a popular measure in China for addressing severe air pollution, in particular fine particulate matter (PM2.5). Here we evaluate the efficacy of these measures, with a particular focus on the strict emission controls imposed on pollution sources in 28 cities in and around the Beijing-Tianjin-Hebei region (BTH) in autumn-winter 2017/2018. For this we use the GEOS-Chem chemical transport model and air pollutant measurements from the national and Beijing local monitoring networks, after evaluating the network data with independent measurements and correcting large biases in the bottom-up emissions inventory. The network measurements are temporally consistent (r > 0.9 for PM2.5 and r > 0.7 for gases) with the independent measurements, though with systematic differences of 5–17 % for nitrogen dioxide (NO2) and 16–28 % for carbon monoxide (CO). The average decrease in monitoring network PM2.5 in BTH in autumn-winter 2017/2018 relative to the previous year is 27 %, declining from 103 to 75 µg m−3. The regional decline in PM2.5 in the model is 20 %, exceeding the regional target of 15 %. According to the model, pollution control measures led to decline in PM2.5 precursor emissions of 0.27 Tg NOx (as NO), 0.66 Tg sulfur dioxide (SO2), 70 Gg organic carbon (OC), and 50 Gg black carbon (BC). We find though that these alone only lead to an 8 % decline in PM2.5 and that interannual variability in meteorology accounts for more than half (57 %) the decline. This demonstrates that year-on-year comparisons are misleading for assessing the efficacy of air pollution measures and should be taken into consideration when extending such measures beyond BTH.
Evaluation of interactive and prescribed agricultural ammonia emissions for simulating atmospheric composition in CAM-Chem
Authors: Vira Julius , Hess Peter , Ossohou Money , Galy-Lacaux Corinne
Published: August 2021

Abstract. Ammonia (NH3) plays a central role in the chemistry of inorganic secondary aerosols in the atmosphere. The largest emission sector for NH3 is agriculture, where NH3 is volatilized from livestock wastes and fertilized soils. Although the NH3 volatilization from soils is driven by the soil temperature and moisture, many atmospheric chemistry models prescribe the emission using yearly emission inventories and climatological seasonal variations. Here we evaluate an alternative approach where the NH3 emissions from agriculture are simulated interactively using the process model FANv2 (Flow of Agricultural Nitrogen, version 2) coupled to the Community Atmospheric Model with Chemistry (CAM-chem). We run a set of six-year global simulations using the NH3 emission from FANv2 and three global emission inventories (EDGAR, CEDS and HTAP) and evaluate the model performance using a global set of multi-component (atmospheric NH3 and NH4+, and NH4+ wet deposition) in-situ observations. Over East Asia, Europe, and North America, the simulations with different emissions perform similarly when compared with the observed geographical patterns. The seasonal distributions of NH3 emissions differ between the inventories, and the comparison to observations suggests that both FANv2 and the inventories would benefit from more realistic timing of fertilizer applications. The largest differences between the simulations occur over data-scarce regions. In Africa, the emissions simulated by FANv2 are 200–300 % higher than in the inventories, and the available in-situ observations from Western and Central Africa, as well as NH3 retrievals from the IASI instrument, are consistent with the higher NH3 emissions as simulated by FANv2. Overall, in simulating ammonia and ammonium concentrations over regions with detailed regional emission inventories, the inventories based on these details (HTAP, CEDS) capture the atmospheric concentrations and their seasonal variability the best. However these inventories can not capture the impact of meteorological variability on the emissions, nor can these inventories couple the emissions to the biogeochemical cycles and their changes with climate drivers. Finally, we show with sensitivity experiments that the simulated time-averaged nitrate concentration in air is sensitive to the temporal resolution of the NH3 emissions. Over the CASTNET monitoring network covering the U.S., resolving the NH3 emissions hourly instead monthly reduced the positive model bias from approximately 80 % to 60 % of the observed yearly mean nitrate concentration. This suggests that some of the commonly reported overestimation of aerosol nitrate over the U.S. may be related to unresolved temporal variability in the NH3 emissions.
A Novel Pathway of Atmospheric Sulfate Formation Through Carbonate Radical

Abstract. Carbon dioxide is considered an inert gas that rarely participates in atmospheric chemical reactions. However, we show here that CO2 is involved in some important photo-oxidation reactions in the atmosphere through the formation of carbonate radicals (CO3∙-). This potentially active intermediate CO3∙- is routinely overlooked in atmospheric chemistry regarding its effect on sulfate formation. Present work demonstrates that SO2 uptake coefficient is enhanced by 17 times on mineral dust particles driven by CO3∙-. It can be produced through two routes over mineral dust surfaces: i) hydroxyl radical + CO32-; ii) holes (h+) + CO32-. Employing a suite of laboratory investigations of sulfate formation in the presence of carbonate radical on the model and authentic dust particles, field measurements of sulfate and (bi)carbonate ions within ambient PM, together with density functional theory (DFT) calculations for single electron transfer processes in terms of CO3∙--initiated S(IV) oxidation, a new role of carbonate radical in atmospheric chemistry is elucidated.

Abstract. Reference mass spectra are routinely used to facilitate source apportionment of ambient organic aerosol (OA) measured by an aerosol chemical speciation monitor (ACSM). However. source apportionment of solid fuel burning emissions can be complicated by the use of different fuels, stoves and burning conditions. In this study, the organic aerosol mass spectra produced from burning a range of solid fuels in several stoves have been compared using an ACSM. The same samples of biomass briquettes and smokeless coal were burnt in a conventional and Ecodesign stove, while different batches of wood, peat, and smoky coal were also burnt in the conventional stove and the OA mass spectra compared to those previously obtained using a boiler stove. The results shows that although certain ions (e.g., m/z 60) remain important markers for solid fuel burning, the peak intensities obtained at specific m/z values were not constant with variations ranging from <5% to >100 %. Using the OA mass spectra of peat, wood and coal as anchoring profiles and the variation of individual m/z values for the upper/lower limits in ME-2 analysis (the limits approach), the respective contributions of these fuels to ambient sub-micron aerosols during a winter period in Dublin were evaluated and compared with the conventional a value approach. The ME-2 solution was stable for the limits approach with uncertainties in the range of 2–7 %, while relatively large uncertainties (8–29 %) were found for the a value approach. Nevertheless, both approaches showed good agreement overall, with the burning of peat (39 % vs 41 %) and wood (14 % vs 11 %) accounting for the majority of ambient organic aerosol during polluted evenings, despite their small uses. This study, thus, accounts for the source variability in ME-2 modelling and provides better constraints on the primary factor contributions to the ambient organic aerosol estimations. The finding from this study has significant implications for public health and policymakers considering that it is often the case that different batches of solid fuels are often burned in different stoves in real-world applications.

Abstract. The recent retreat of nearly all glaciers and ice caps (GICs) located in Arctic regions is one of the most clear and visible signs of ongoing climate change. This paper synthesizes published records of Holocene GIC fluctuations from lake archives, placing their recent retreat into a longer–term context. Our compilation includes sixty–six lake–based GIC records (plus one non–lake–based record from the Russian Arctic) from seven Arctic regions: Alaska; the archipelagos of the eastern Canadian Arctic; GICs peripheral to the Greenland Ice Sheet; Iceland; the Scandinavian peninsula; Svalbard; and the Russian high Arctic. For each region, and for the full Arctic, we summarize evidence for when GICs were smaller than today or absent altogether, indicating warmer than present summers, and evidence for when GICs regrew in lake catchments, indicating summer cooling. Consistent with orbitally driven high boreal summer insolation in the early Holocene, the pan–Arctic compilation suggests that the majority (50 % or more) of studied GICs were smaller than present or absent by ~10 ka. The regional compilations suggest even earlier GIC loss, and thus warmth, in the Russian Arctic and in Svalbard. We find the highest percentage (>90 %) of Arctic GICs smaller than present or absent in the middle Holocene ~7–6 ka, probably reflecting more spatially ubiquitous and consistent summer warmth during this period than in the early Holocene. Following this interval of widespread warmth, our compilation shows that GICs across the Arctic began to regrow, and summers began to cool by ~6 ka. Together, the pan–Arctic records also suggest two periods of enhanced GIC growth in the mid–to–late Holocene, from ~4.5–3 ka and after ~2 ka. The regional records show substantial variability in the timing of GIC regrowth within and between regions, suggesting that the Arctic did not cool synchronously despite the smooth and hemispherically symmetric decline in Northern Hemisphere summer insolation. In agreement with other studies, this implies a combined response to glacier–specific characteristics such as topography, and to other climatic forcings and feedback mechanisms, perhaps driving periods of increased regional cooling. Today, the direction of orbital forcing continues to favor GIC expansion, however, the rapid retreat of nearly all Arctic GICs underscores the current dominance of anthropogenic forcing on GIC mass balance. Our review finds that in the first half of the Holocene, most of the Arctic’s small GICs became significantly reduced or melted away completely in response to summer temperatures that, on average, were only moderately warmer than today. In comparison, future projections of temperature change in the Arctic far exceed estimated early Holocene values in most locations, portending the eventual loss of most of the Arctic’s small GICs.
Short communication: Inverse isochron regression for Re–Os, K–Ca and other chronometers
Authors: Li Yang , Vermeesch Pieter
Published: August 2021

Abstract. Conventional Re–Os isochrons are based on mass spectrometric estimates of 187Re/188Os and 187Os/188Os, which often exhibit
strong error correlations that may obscure potentially important geological complexity. Using an approach that is widely accepted in 40Ar/39Ar and U–Pb geochronology, we here show that these error correlations are greatly reduced by applying a simple change of variables, using 187Os as a common denominator. Plotting
188Os/187Os vs. 187Re/187Os produces an
“inverse isochron”, defining a binary mixing line between an inherited
Os component whose 188Os/187Os ratio is given by the
vertical intercept, and the radiogenic 187Re/187Os ratio, which corresponds to the horizontal intercept. Inverse isochrons facilitate
the identification of outliers and other sources of data dispersion.
They can also be applied to other geochronometers such as the K–Ca
method and (with less dramatic results) the Rb–Sr, Sm–Nd and Lu–Hf
methods. Conventional and inverse isochron ages are similar for
precise datasets but may significantly diverge for imprecise ones. A
semi-synthetic data simulation indicates that, in the latter case, the
inverse isochron age is more accurate. The generalised inverse
isochron method has been added to the IsoplotR toolbox for
geochronology, which automatically converts conventional isochron
ratios into inverse ratios, and vice versa.

Abstract. Climate resilience is an emerging issue at contaminated sites and hazardous waste sites, since projected climate shifts (e.g., increased/decreased precipitation) and extreme events (e.g., flooding, drought) could affect ongoing remediation or closure strategies. In this study, we develop a reactive transport model (Amanzi) for radionuclides (uranium, tritium, and others) and evaluate how different scenarios under climate change will influence the contaminant plume conditions and groundwater well concentrations. We demonstrate our approach using a two-dimensional reactive transport model for the Savannah River Site F-Area, including mineral reaction and sorption processes. Different recharge scenarios are considered by perturbing the infiltration rate from the base case, as well as considering cap failure and climate projection scenarios. We also evaluate the uranium and nitrate concentration ratios between scenarios and the base case to isolate the sorption effects with changing recharge rates. The modeling results indicate that the competing effects of dilution and remobilization significantly influence pH, thus changing the sorption of uranium. At the maximum concentration on the breakthrough curve, higher aqueous uranium concentration implies that sorption is reduced with lower pH due to remobilization. To better evaluate the climate change impacts in the future, we develop the workflow to include the downscaled CMIP5 (Coupled Model Intercomparison Project) climate projection data in the reactive transport model, and evaluate how residual contamination evolves through 2100 under four climate Representative Concentration Pathway (RCP) scenarios. The integration of climate modeling data and hydro-geochemistry models enables us to quantify the climate change impacts, assess which impacts need to be planned for, and therefore assist climate resiliency efforts and help guide site management.
Space-time clustering of climate extremes amplify global climate impacts, leading to fat-tailed risk
Authors: Bonnafous Luc , Lall Upmanu
Published: August 2021

Abstract. We present evidence that the global juxtaposition of major assets relevant to the economy with the space and time expression of extreme floods or droughts leads to a much higher aggregate risk than would be expected by chance. Using a century-long, globally gridded time series that indexes net water availability, every year we compute local occurrences of an extreme “dry” or “wet” condition for a specified duration and return period. A global exposure index is then derived for major mining commodities by weighting extreme event occurrence by local production exposed. We note significant spatial and temporal clustering of exposure at the global level leading to the potential for fat-tailed risk associated with investment portfolios and supply chains. This may not be a surprise to climate scientists familiar with the space-time patterns of interannual to decadal climate oscillations that can affect remote regions through teleconnections. However, the traditional approach of climate risk analysis
only considers local or point extreme value analysis and hence does not
account for temporal and spatial clustering of exposure for global portfolios. As multinational enterprises and supply chains assess and
disclose physical climate risks, they need to consider the much higher
chance that they may have multiple assets that may be exposed to extreme wet
and/or dry climate extremes in the same year.
Variscan structures and their control on latest to post-Variscan basin architecture; insights from the westernmost Bohemian Massif and SE Germany
Authors: Fazlikhani Hamed , Bauer Wolfgang , Stollhofen Harald
Published: August 2021

Abstract. The Bohemian Massif exposes structures and metamorphic rocks remnant from the Variscan Orogeny in Central Europe and is bordered by the Franconian Fault System (FFS) to the west. Across the FFS, possible presence of Variscan units and structures are buried by Permo-Mesozoic sedimentary rocks. We integrate existing DEKORP 2D seismic reflection, well and surface geological data with the newly acquired FRANKEN 2D seismic survey to investigate the possible westward continuation of Variscan tectonostratigraphic units and structures, and their influence on latest to post-Variscan basin development. Subsurface Permo-Mesozoic stratigraphy is obtained from available wells and are tied to seismic reflection profiles using a synthetic seismogram calculated from density and velocity logs. Below the sedimentary cover, three main basement units are identified using seismic facies descriptions that are compared with seismic reflection characteristics of exposed Variscan units east of the FFS. Our results show that Upper Paleozoic low-grade metasedimentary rocks and possible Variscan nappes are bounded and transported by Variscan shear zones to ca. 65 km west of the FFS. Basement seismic facies in the footwall of the Variscan shear zones are interpreted as Saxothuringian basement. We show that the location of normal fault-bounded latest to post-Variscan Upper Carboniferous-Permian basins are controlled by the geometry of underlying Variscan shear zones. Some of these Upper Carboniferous-Permian normal faults reactivated as steep reverse faults during the regional Upper Cretaceous inversion. Our results also highlight that reverse reactivation of normal faults gradually decreases west of the FFS.

“A Stepping Stone That Just Pushed Me Further Into Wanting to Go to University”: Student Perspectives on ‘What Works’ for Effective Outreach Strategies for Indigenous Students
Authors: Barney Katelyn , Williams Hayley
Published: August 2021

In Australia, there are numerous outreach initiatives run by universities for Indigenous high school students that attempt to elevate aspirations of Indigenous students to go to university. The theoretical case for these initiatives is strong as much data exists surrounding the barriers Indigenous students face in entering university. However, the research and evidence base for these equity programs remains largely underdeveloped and limited (Bennett et al., 2015). Drawing on findings from interviews with Indigenous university students as part of a National Centre for Student Equity in Higher Education (NCSEHE) Equity Fellowship, this paper identifies what works and what areas to strengthen in Indigenous specific outreach programs. The paper concludes by discussing the development of strategies and resources to build the evidence base of effective outreach activities for Indigenous students.

We interrogated a students as partners (SaP), co-curricular program that focuses on supporting student learning. To center power and equity in SaP, the program was grounded in social design-based experiment methodology. We considered the manifestation of power and equity beyond higher education, to that of broader socio-political contexts. Collaborative autoethnography (CAE) was used to garner a richer understanding of student-staff experiences of the program. Through CAE, power emerged as central to our collective experiences, and a recognition that power asymmetry in students as partners programs is complex and multi-layered. We found that to address power imbalances in these programs requires considered strategies and intentional designs. Further, CAE, in and of itself, can be a powerful way to foster self-awareness, mutual trust, respect, and the acknowledgement of others in student-staff partnerships. We conclude by recommending the importance of deliberate design for equity and power towards consequential learning and transformational change.
