Negotiating salt worlds: causation and material participation

ABSTRACT In this article, we analyze the role of measurement practices in a public dispute about the impacts of mining in the Netherlands. Drawing on studies of material participation and agential realism, we analyze how measurement practices shape the boundaries of subsurface objects. We detail how these boundaries become relevant for assessing mining impacts and show how this enables and constrains material participation. Simply put, if a process or thing is not measured into being, it cannot participate in negotiations about causality and impact. Our analysis shows that scientific conventions narrowly determined what measurements are credible and, consequently, limited the participation of other objects and processes in negotiations about damage and compensation. This underscores how ontological disagreements about the existence and measurability of subsurface processes affect what claims can be made. We conclude by discussing conditions for pluralist and equitable processes of material participation in measurement practices.
Myeloid-Specific Pyruvate-Kinase-Type-M2-Deficient Mice Are Resistant to Acute Lung Injury

Infiltration of polymorphonuclear neutrophils (PMNs) plays a central role in acute lung injury (ALI). The mechanisms governing PMN inflammatory responses, however, remain incompletely understood. Based on our recent study showing a non-metabolic role of pyruvate kinase type M2 (PKM2) in controlling PMN degranulation of secondary and tertiary granules and consequent chemotaxis, here we tested a hypothesis that Pkm2-deficient mice may resist ALI due to impaired PMN inflammatory responses. We found that PMN aerobic glycolysis controlled the degranulation of secondary and tertiary granules induced by fMLP and PMA. Compared to WT PMNs, Pkm2-deficient (Pkm2-/-) PMNs displayed significantly less capacity for fMLP- or PMA-induced degranulation of secondary and tertiary granules, ROS production, and transfilter migration. In line with this, myeloid-specific Pkm2-/- mice exhibited impaired zymosan-induced PMN infiltration in the peritoneal cavity. Employing an LPS-induced ALI mouse model, LPS-treated Pkm2-/- mice displayed significantly less infiltration of inflammatory PMNs in the alveolar space and a strong resistance to LPS-induced ALI. Our results thus reveal that PKM2 is required for PMN inflammatory responses and deletion of PKM2 in PMN leads to an impaired PMN function but protection against LPS-induced ALI.
The Response of Cd Chemical Fractions to Moisture Conditions and Incubation Time in Arable Land Soil

Heavy metal pollution in soils is an issue of global concern, and many scholars have focused on Cadmium (Cd) because of its strong biological migration and toxicity. This study explored arable land soil, changes in external Cd contamination processes and its response to soil moisture conditions, and indoor simulation. After adding an external source of 5 mg/kg d.w. , the distribution of soil Cd fractions content, EXC-Cd, CAB-Cd, FMO-Cd, OM-Cd, and RES-Cd, were continuously monitored under different water management regimes, and correlation analysis and regression equations were calculated. The results show that after external Cd entered arable land soils, the binging strength of pollutants and soil gradually increased with incubation time, and the distribution of Cd chemical forms was more stable under different water management regimes. The oversaturated water content promotes the transformation of EXC-Cd to other forms. The transformation of CAB-Cd fractions can be accelerated to other fractions by field capacity, and the active conversion period was 30–60 d. Not all Cd fractions correlated between each other, under the four water management regimes, but it seems that the reducibility of the soil environment was more conducive to external Cd fixation and stability. The response surface design method (RSM) was used to establish quantitative regimes between Cd fractions with incubation time and soil moisture, and the soil moisture content and incubation time had an obvious effect on FMO-Cd content, with R2 = 0.9542.
Understanding the Influence of Pavement Conditions on Cyclists’ Perception of Safety and Comfort Using Surveys and Eye Tracking

Although infrequently included in studies of cyclists’ perceived safety, pavement condition has an influence on cyclists’ stress and related perceptions of safety. Few studies investigating the influence of pavement condition on cyclists’ perceived safety have developed actionable information for industry professionals. This paper aims to fill that gap by identifying which forms of pavement distress most influence cyclists’ perceived safety and comfort. The study used a combination of online surveys and field experiments. The 181 complete responses to the online survey showed potholes were the most important pavement distress for perceived safety and comfort. Eye-tracking data from 17 field participants were collected and analyzed for the following: whether participants fixated on the distresses; when; and for how long. These results showed that unevenness attracted the most fixations for the longest duration. In mixed traffic scenarios, participants tended to fixate less frequently compared with the separated facility, suggesting a potential safety concern. These findings are compiled into the following recommendations for cyclist-focused maintenance practices: (a) the need to focus on perceived safety, and on the extent, avoidability, and visibility of pavement distresses; (b) shift cyclists to separated facilities; (c) prioritize mixed facilities for routine maintenance; (d) prioritize bicycle lanes for high-cost repairs; (e) shift street-sweeping operations to bicycle lanes; (f) develop new deterioration models and fill mix designs; and (g) determine the appropriate treatment, maintenance activity, and timing. These recommendations can be used by asset management planners and maintenance personnel to improve the perceived safety and comfort of their cycle network.
Impact of COVID -19 on the Psychosocial Status of Saudi and Egyptian Population: Comparative Study

Egypt Abstract Background : The uncertainty and limited predictability surrounding the course of the coronavirus disease 2019 (COVID- 19) pandemic has had negative consequences on people’ s psychosocial health status. The study aimed to explore the impact of COVID-19 on the psychosocial status of Saudi and Egyptian population using a comparative design. Subjects and Method: Design: A descriptive cross-sectional study was conducted between April 10 and 30, 2020. Subjects: Considering 517 participants from both countries (230 Egyptians, and 287 Saudis). For the research purpose, psychosocial status was defined as the general psychological and social conditions of the person that encompasses the anxiety, depression, and obsession feelings of the individual. Tools used were COVID-19 Anxiety Scale (CAS), Depressive symptoms questionnaire (DSQ), and obsessive-compulsive disorder questionnaire (OCD). Results: The mean psychosocial distress scores were significantly higher among Egyptian participants compared to Saudis. Anxiety was significantly lower among Saudis older than 55 years old compared to Saudis from younger ages. Among Egyptian participants, those who were married, employed, and/or older than 55 years had significantly lower depression and OCD scores; among Saudis, women and unemployed had significantly higher depression and OCD scores. Overall, anxiety, depression, and OCD scores had a significantly positive correlation with one another. Conclusions: Egyptians had greater prevalence rates of anxiety, depression, and OCD than Saudis. Many factors served as significant independent predictors for anxiety, depression, and OCD levels including gender, nationality, and employment status. The study reveals some factors associated with psychological impact that may be used to formulate psychological interventions to assist patients with vulnerable mental health statuses during COVID-19 pandemic and future health emergencies.
BIOLOGICAL STUDIES ON FLAT BREAD FORTIFIED WITH DIFFERENT SOURCES OF ZINC

Hypozincemic rats fed on flat bread supplemented with different sources of zinc, i.e. natural (20% soy flour) or chemical (ZnO or ZnSO 4 at 8 mg/100 g flour) compared with control (100% wheat flour 72%). Biological evaluation of the experimental rats such as: body weight gain, weight of organs, glucose level, serum alkaline phosphatase, T 3 and T 4 , serum testosterone, zinc in serum and zinc in tibia were estimated. The data showed that feeding flat bread supplemented with different sources of zinc increased the body weight and weight of organs. Chemical sources of zinc decreased glucose level compared with natural source. Zinc supplementation increased the level of T 3 , T 4 and serum testosterone in rats. Zinc in serum and tibia were increased by zinc supplementation.
Effect of Nano-Sized Poly(Butyl Acrylate) Layer Grafted from Graphene Oxide Sheets on the Compatibility and Beta-Phase Development of Poly(Vinylidene Fluoride) and Their Vibration Sensing Performance

In this work, graphene oxide (GO) particles were modified with a nano-sized poly(butyl acrylate) (PBA) layer to improve the hydrophobicity of the GO and improve compatibility with PVDF. The improved hydrophobicity was elucidated using contact angle investigations, and exhibit nearly 0° for neat GO and 102° for GO-PBA. Then, the neat GO and GO-PBA particles were mixed with PVDF using a twin screw laboratory extruder. It was clearly shown that nano-sized PBA layer acts as plasticizer and shifts glass transition temperature from −38.7 °C for neat PVDF to 45.2 °C for PVDF/GO-PBA. Finally, the sensitivity to the vibrations of various frequencies was performed and the piezoelectric constant in the thickness mode, d33, was calculated and its electrical load independency were confirmed. Received values of the d33 were for neat PVDF 14.7 pC/N, for PVDF/GO 20.6 pC/N and for PVDF/GO-PBA 26.2 pC/N showing significant improvement of the vibration sensing and thus providing very promising systems for structural health monitoring and data harvesting.
Torreﬁed Biomass Pellets—Comparing Grindability in Different Laboratory Mills

The ﬁring and co-ﬁring of biomass in pulverized coal ﬁred power plants around the world is expected to increase in the coming years. Torrefaction may prove to be a suitable way of upgrading biomass for such an application. For transport and storage purposes, the torreﬁed biomass will tend to be in pellet form. Whilst standard methods for the assessment of the milling characteristics of coal exist, this is not the case for torreﬁed materials—whether in pellet form or not. The grindability of the fuel directly impacts the overall efﬁciency of the combustion process and as such it is an important parameter. In the present study, the grindability of different torreﬁed biomass pellets was tested in three different laboratory mill types; cutting mill (CM), hammer mill (HM) and impact mill (IM). The speciﬁc grinding energy (SGE) required for a deﬁned mass throughput of pellets in each mill was measured and results were compared to other pellet characterization methods (e.g., durability, and hardness) as well as the modiﬁed Hardgrove Index. Seven different torreﬁed biomass pellets including willow, pine, beech, poplar, spruce, forest residue and straw were used as feedstock. On average, the particle-size distribution width (across all feedstock) was narrowest for the IM (0.41 mm), followed by the HM (0.51 mm) and widest for the CM (0.62 mm). Regarding the SGE, the IM consumed on average 8.23 Wh/kg while CM and HM consumed 5.15 and 5.24 Wh/kg, respectively. From the three mills compared in this study, the IM seems better ﬁt for being used in a standardized method that could be developed in the future, e.g., as an ISO standard.
GROWTH AND DEVELOPMENT OF Oryzaephilus surinamensis (L.) (COLEOPTERA: SILVANIDAE) IMMATURE STAGES ON SOME FOOD KINDS

: The saw-toothed grain beetle, Oryzaephilus surinamensis (L.) is an important pest of many stored product foods. The effect of insect infestation on four various of whole food kinds as semi-dry date, dry date fruits, white sesame and reddish yellow sesame seeds as well as four food kinds of crushed seeds (chickpea, corn, rice and groundnut) as compared with standard diet (wheat flour, crushed wheat and dry yeast powder at 5:5:1, respectively) was investigated in the laboratory of Plant Protection Department, Faculty of Agriculture, Zagazig University, Egypt. Insect parameters on the tested food kinds as regards to resistance were duration of developmental stages, number of F 1 progeny, growth index and weight loss (%) after one month of storage. All tested parameters were significantly affected by food kinds except the duration of pupal stage in whole foods. The shortest mean insect complete developmental period was 19.85 days on standard diet, while the longest one was 29.18 days on whole reddish yellow sesame seeds and 35.05 days on crushed groundnut. Values of the growth index (GI) increased from 3.22 to 3.76 on whole reddish yellow sesame seeds and crushed chickpea, respectively compared to 4.64 on standard diet. The wet weight loss (%) ranged from 0.50 and 0.67% in whole sesame seeds (white and reddish yellow) and crushed groundnut, suscessively compared to11.17% in standard diet. The relative wet weight loss (%) in whole seeds reached its minimum (1.94%) in each of whole white and reddish yellow sesame seeds and reached its maximum (43.23%) in standard diet, while in crushed foods, the lowest value was 3.16% in crushed groundnut as compared with the standard diet which recorded the highest percent 52.76%. All tested foods either whole or crushed were infested with O. surinamensis and no completely immune food was found free from the insect infestation but the insect preferred crushed foods and some foods than another.
A New Cost-Benefit Economic Model Approach of Hemodialyzer Reuse

In this study, a new cost-benefit economic model for hemodialyzer reuse has been developed considering all of the direct costs (dialyzer price, disinfection fluid price, reverse osmosis water cost, personnel, and miscellaneous) as well as the number of disinfections applied to the hemodialyzer. The maximum number of disinfections/reuses for different models of hemodialyzer was estimated using statistical analysis based on the information obtained from a total of 60 adult patients on maintenance hemodialysis for approximately 4 years; from a hospital in Santiago de Cuba province, Cuba. An equal number of treatments (100) was evaluated for each hemodialyzer including 2,800 total reuses. The total cost savings for reuse/disinfection using the new economic approach is compared with the single-use modality. Obtained results by applying the proposed model indicated that the correlation between the economic advantages of the reuse/disinfection process in the total cost of the hemodialysis treatment significantly depends on the type of hemodialyzer used for the treatment, the disinfection price, the virgin hemodialyzer price, the disposal cost and its price reduction because of the number of reuses and the maximum possible reuses that could be applied to the hemodialyzer.
Relating Slip Behavior to Off‐Fault Deformation Using Physical Models

Deformation in transform systems is accommodated by discrete fault slip and distributed off‐fault deformation. Here, we consider how a change in slip behavior along a fault can influence the distribution between on‐ and off‐fault deformation. We use a physical experiment to simplify the geometry, material properties, boundary conditions, and slip history along a strike‐slip fault to directly observe patterns of off‐fault deformation. We document deformation of a silicone slab on a simple shear apparatus using particle image velocimetry (2D) and photogrammetry (3D). The experimental results show regions of topographic highs and lows on either side of the slip transition that grow, evolve, and are displaced with progressive strain. The experimental dilatation field shares similarities with strain fields in central California along the San Andreas fault, which suggests that a change in slip behavior may explain some of the real‐world patterns in short‐ and long‐term deformation.
Through Their Eyes: Gifted Students’ Views on Integrating History of Mathematics Embedded Videos Into Mathematics Classrooms

This study examined gifted students’ views on integrating the history of mathematics embedded videos into mathematics classrooms. The research was conducted with 30 fifth-grade students who were identified as gifted with the WISC-R Intelligent Test Score and aptitude test. Data were collected through students’ video reflection papers after watching the videos on biographies of mathematicians. Content analysis was conducted to analyze data collected with reflection papers. The findings were grouped as history as a tool and history as a goal. Under the title of history as a tool, the students’ reflections were categorized as history as a cognitive tool and history as a motivational tool. As a cognitive tool, students stated that the history of mathematics embedded videos expanded their knowledge of mathematicians’ early work and their occupations. As a motivational tool, the history of mathematics embedded videos helped raise students’ curiosity about mathematicians and their works, and mathematical concepts, increased their motivation for invention, and developed a positive attitude toward mathematics and learning. On the other hand, under the title of history as a goal, the students stated that the history of mathematics embedded videos broaden their knowledge of mathematicians and their contributions, mathematical concepts, and mathematical evolution. Thus, the videos can be used as enrichment activities for gifted elementary students in mathematics classrooms.
MDM2-Mediated Ubiquitination of RXRβ Contributes to Mitochondrial Damage and Related Inflammation in Atherosclerosis

A novel function of retinoid X receptor beta (RXRβ) in endothelial cells has been reported by us during the formation of atherosclerosis. Here, we extended the study to explore the cellular mechanisms of RXRβ protein stability regulation. In this study, we discovered that murine double minute-2 (MDM2) acts as an E3 ubiquitin ligase to target RXRβ for degradation. The result showed that MDM2 directly interacted with and regulated RXRβ protein stability. MDM2 promoted RXRβ poly-ubiquitination and degradation by proteasomes. Moreover, mutated MDM2 RING domain (C464A) or treatment with an MDM2 inhibitor targeting the RING domain of MDM2 lost the ability of MDM2 to regulate RXRβ protein expression and ubiquitination. Furthermore, treatment with MDM2 inhibitor alleviated oxidized low-density lipoprotein-induced mitochondrial damage, activation of TLR9/NF-κB and NLRP3/caspase-1 pathway and production of pro-inflammatory cytokines in endothelial cells. However, all these beneficial effects were reduced by the transfection of RXRβ siRNA. Moreover, pharmacological inhibition of MDM2 attenuated the development of atherosclerosis and reversed mitochondrial damage and related inflammation in the atherosclerotic process in LDLr-/- mice, along with the increased RXRβ protein expression in the aorta. Therefore, our study uncovers a previously unknown ubiquitination pathway and suggests MDM2-mediated RXRβ ubiquitination as a new therapeutic target in atherosclerosis.
