On the Contribution of low-mach, high-beta Shocks to the Cosmic Ray Spectrum
Authors: Jan van Marle Allard
Published: October 2020

Astrophysical shocks accelerate particles through the Fermi acceleration process, which involves a charged particle repeatedly crossing the shock after being reflected by the local magnetic field and gaining momentum. Eventually, the particles reach relativistic speeds and can be observed as cosmic rays. This is a self self-sustaining interaction because the presence of non-thermal particles in the shock-region causes instabilities in the magnetic field, which in turn allow the magnetic field to reflect the particles. This process has been studied extensively in the case of high-Mach, low-β shocks, such as those that are found in stellar wind collisions and supernovae. However, there are astrophysical shocks, such as those that occur in colliding galaxy clusters, that are characterized by a low sonic Mach number, combined with a high plasma-beta. So far, these shocks have been largely neglected, and little is known about their ability to accelerate particles. Using a combined PIC-MHD code, we have performed a series of numerical simulations of low-Mach, high-beta shocks, to investigate the interaction between the particles and the magnetic field under such conditions. We find that even low-Mach shocks are capable of accelerating charged particles. However, due to the behaviour of the magnetic field, the process tends to be relatively inefficient, reducing the effective contribution to the cosmic ray spectrum. Furthermore, the interaction tends to radically change the nature of the shock itself, which indicates that further study is required to quantify the shocks’ long-term behaviour.

Authors: Heihsel Michael , Lenzen Manfred , Behrendt Frank
Published: October 2020

For many arid countries, desalination is considered as the final possible option to ensure water availability. Although seawater desalination offers the utilisation of almost infinite water resources, the technology is associated with high costs, high energy consumption and thus high carbon emissions when using electricity from fossil sources. In our study, we compare different electricity mixes for seawater desalination in terms of some economic, social and environmental attributes. For this purpose, we developed a comprehensive multi-regional input-output model that we apply in a hybrid life-cycle assessment spanning a period of 29 yr. In our case study, we model desalination plants destined to close the water gap in the Murray-Darling basin, Australia’s major agricultural area. We find that under a 100%-renewable electricity system, desalination consumes 20% less water, emits 90% less greenhouse gases, and generates 14% more employment. However, the positive impacts go hand in hand with 17% higher land use, and a 10% decrease in gross value added, excluding external effects.

Authors: Hermawan Agus , Sarjana  , Ambarsari Indrie
Published: October 2020

Indonesian Ministry of Agriculture in 2013 launched agricultural bio-industry policy for sustainable development, which is targeted in 2045. Bio-industry as the agricultural policy is interesting since bio-industry commonly associated and practiced by giant industry or a multinational corporation. Its contrasts with Indonesian condition, which the farmers only have a small land or even land-less. As a solution, AIAT Central Java developed a bio-cycle approach that accorded to the bio-industry concept and suitable under small farmers’ circumstances. The bio-cycle model was developed from the previous integrated crop-livestock systems approach. The approach was based on the following principles, i.e. (1) reduce biomass loss and external input by using all of the agro biomass as feedstock, (2) reuse residual biomass and processed waste and (3) recycling final products, waste products, and processed products. The bio-cycle approach has been implemented in Central Java Province, both in irrigated and in high land areas since 2015. The implementation of the bio-cycle approach under farmers’ circumstances was promising. Aside from the increasing of farmer’s income and farming efficiency, it is possible to develop sustainable bioenergy in rural areas through the implementation of this approach.

Published: October 2020

The research objective was to design a collective action model in the context of household independence in overcoming the temporary loss income (TLI) period during the rubber replanting process. The research partner was the Sumber Rezeki Farmer Group (SRFG) in Mestong District, Jambi, Indonesia. The results showed that collective action in integrated waste processing to produce TCI and BA+ can work well but not followed by inter-cropping cultivation implementation. The BA+ prototype technology with capacity 1,100 liters/period more advantages over conventional methods because it only takes 18 days with clearer and loss of pungent odor. The substitution power of food crops was only 49,27% from potential temporary loss income with the highest in food-corn which’s 55.83%. Conversely, the food crops productivity implemented was not targeted as achieved by planting demonstration plot scale. The main inhibiting factor the water availability which is highly dependent on the season, and animal wild pest attacks such as monkeys and wild boar. Based on the results it can be concluded that the collective action model had not been effective at the implementation stage so that further research is needed to address the water management and wild animal pests control problems.

Authors: Wang Yun-Long , Chen Sheng-Ping
Published: October 2020

In this paper, a quasi-heat-capacity fiber laser is designed, which uses a heat sink to store heat during the operation time, and uses a low-energy cooling system to cool down slowly. Compared with conventional water-cooled or air-cooled fiber lasers, this quasi-heat-capacity fiber laser has a compact structure with low-energy consumption, which might be useful for platforms that have strict requirements for volume, weight and energy consumption. By using the finite element analysis (FEA) method, a detailed quantitative thermal analysis of the proposed quasi-heat-capacity fiber laser is investigated. The laser heat source consists of two pumping laser diodes (LDs), gain fibers, and an electronic power source. During operation, the heat is stored only through an aluminum heat sink with a limited mass of 5 kg. The lasing- on-time of the laser is defined as the time when the temperature of LD bottom plate increases from 20 °C to 30 °C for the first time in a certain period of working time, which is the best working temperature range of the wavelength stabilized LDs. Numerical simulation results show that when the fiber laser works in heat capacity mode, the lasing-on-time can be effectively improved.

Evaluation of FNA (n = 4), effusion (n = 4), and TP (n = 3) in nine adult and two pediatric patients demonstrated cellular samples (n = 11), epithelioid cells with rhabdoid morphology (n = 9), eccentrically located nuclei with prominent nucleoli (n = 7), and cytoplasmic bodies (n = 4); two patients were diagnosed on FNA with cell block. Immunohistochemistry (IHC) demonstrated SMARCB1 loss in all cases and keratin and/or EMA expression in all but the epithelioid MPNST; NGS identified SMARCB1 inactivation in both cases.

Conclusions

SMARCB1-deficient soft tissue neoplasms comprise a variety of tumors with epithelioid morphology and frequent expression of keratin and/or EMA. Recognition of characteristic rhabdoid morphology on cytology can prompt IHC and/or NGS testing for SMARCB1 deficiency and help establish the diagnosis.

Objectives

We sought to investigate the clinical utility of flow cytometry (FC) and fluorescence in situ hybridization (FISH) in the workup of myeloma.

Methods

We retrospectively reviewed the reports of bone marrow biopsies received for myeloma evaluation between October 2015 and January 2019.

Results

A total of 1,708 biopsy specimens from 469 myeloma patients (mean age, 64.5 years [SD, 9.3]; female, 41.4%) were reviewed. Both FC and FISH had comparable detection rates at the time of initial diagnosis (97.6% vs 98.8%) and for follow-up cases (28.6% vs 28.2%). FC and FISH results were concordant in 98.8% of the initial diagnosis cases and 89.6% of the follow-up cases. The FISH-positive (FISH+)/FC-negative (FC−) discordance and FISH−/FC+ discordance occurred among 81 (5.0%) and 87 (5.4%) follow-up cases. In comparison with all concordant cases, FISH+/FC− discordant cases were more likely to have received treatment with daratumumab (P < .05).

Conclusions

Plasma cell–enriched FISH and FC have comparable abnormal plasma cell detection rates, and approximately 10% of the follow-up cases have discordant FISH and FC results in which residual disease is detected by only one of these modalities. FISH testing should be considered for cases with negative FC, especially in patients who have received treatment with daratumumab or in cases in which there is concern about specimen adequacy.

Authors: Shmookler Aaron D , Nichols Tracie L , Perrotta Peter L
Published: October 2020

Objectives

The role of transfusion medicine consultative services in prospectively auditing (PA) orders for four-factor prothrombin complex concentrate (4F-PCC) was evaluated at an academic medical center.

Methods

Data from 4 years of 4F-PCC orders were obtained from the laboratory information system, and electronic health records of patients receiving concentrate were reviewed.

Results

4F-PCC was ordered for 427 patients with warfarin-, apixaban-, or rivaroxaban-associated hemorrhage. Turnaround time (TAT) to prepare 4F-PCC was longer when PA-recommended dose adjustments were needed (85 vs 66 minutes, P = .03). There was no difference in TAT between patients who died and those who were ultimately discharged (60 vs 70, P = .22). TAT was shortest for orders originating in the emergency department (ED) compared with other locations (64 vs 85, P < .001), and ED TAT was not associated with patient outcomes in ED patients. PA and dose adjustments reduced amounts of concentrate issued by 27 IU per dose (P = .01). Median international normalized ratio less than 1.3 after 4F-PCC transfusion was achieved for all anticoagulants after dose adjustments. PA did not affect order cancellation or product wastage rates.

Conclusions

PA can ensure 4F-PCC is dosed appropriately without affecting patient outcomes.
Trait Impulsivity Impedes Maturing Out of Problem Drinking Among Socially Anxious Undergraduates

Aims

Alcohol use follows a developmental trajectory—steadily increasing and peaking in the early stages of emerging adulthood (e.g. first year of university) and declining thereafter. While most individuals ‘mature out’ of problem drinking as they move through emerging adulthood, some continue to drink heavily and experience serious problems. Tension reduction theory identifies social anxiety (SA) as a potential risk factor for problem drinking during emerging adulthood. However, mixed data suggest that the associations between SA and drinking behaviours are not straightforward. Cross-sectional studies demonstrate that socially anxious emerging adults are at risk for problem drinking, but only if they are also high in trait impulsivity. This study aimed to expand on previous work by examining trait impulsivity as moderator of the prospective associations between SA and maturing out of problem drinking in emerging adulthood.

Methods

Undergraduates (N = 302) completed online self-reports at regular intervals (6-months) over an 18-month period, resulting in four waves of data.

Results

Unconditional latent growth curve models indicated that alcohol problems (but not use) declined linearly over time. Next, conditional growth curve models revealed that SA was associated with impeded maturing out of alcohol problems, but this effect was only present in socially anxious participants with high levels of trait impulsivity.

Conclusion

Our study advances growing literature on the crucial moderating role that impulsivity plays in the SA pathway to problem drinking. Clinical interventions for problem drinking among socially anxious students should both assess for and target concurrent impulsivity.
Work Exposure to VOC in Storage Areas of Retail Stores

Published: October 2020

Poor indoor air quality (IAQ) has been linked to airway disease and early deaths. The ESQUISSE study of IAQ conducted by the French Research and Safety Institute (INRS), characterized the concentrations of various volatile organic compounds (VOCs) in 10 retail stores and storage areas. The IAQ was generally better in sales areas than storage areas, which are more often unventilated and overloaded with new products. For example, in clothing stores, formaldehyde concentrations between 29.0 and 45.0 µg m−3 were measured in non-ventilated storage areas located in the basement; in sales areas, concentrations did not exceed 10.2 µg m−3. Similarly, total VOC (TVOC) concentrations in the two main storage areas were 1153 and 1223 µg m−3 toluene equivalent, whereas they were less than 77.0 µg m−3 toluene equivalent in all sales areas. Many employees work in these high-exposure areas either temporarily or for the entire day, unpacking boxes, placing products on shelves, or collecting products. Reporting primarily on formaldehyde, toluene, or TVOC concentrations, this article shows, in addition to the distinction between sales and storage areas, how an unpacking task can affect an employee’s exposure, and an example of the impact of ambient temperature on VOC concentrations. The results presented clearly highlight the issue of occupational exposure of workers in storage areas.

Published: October 2020

Objective

Telephone-based cognitive assessment (TBCA) has long been studied but less widely adopted in routine neuropsychological practice. Increased interest in remote neuropsychological assessment techniques in the face of the coronavirus 2019 (COVID-19) pandemic warrants an updated review of relevant remote assessment literature. While recent reviews of videoconference-based neuropsychological applications have been published, no updated compilation of empirical TBCA research has been completed. Therefore, this scoping review offers relevant empirical research to inform clinical decision-making specific to teleneuropsychology.

Method

Peer-reviewed studies addressing TBCA were included. Broad search terms were related to telephone, cognitive, or neuropsychological assessment and screening. After systematic searching of the PubMed and EBSCO databases, 139 relevant articles were retained.

Results

In total, 17 unique cognitive screening measures, 20 cognitive batteries, and 6 single-task measures were identified as being developed or adapted specifically for telephone administration. Tables summarizing the identified cognitive assessments, information on diagnostic accuracy, and comparisons to face-to-face cognitive assessment are included in supplementary materials.

Conclusions

Overall, literature suggests that TBCA is a viable modality for identifying cognitive impairment in various populations. However, the mode of assessment selected clinically should reflect an understanding of the purpose, evidence, and limitations for various tests and populations. Most identified measures were developed for research application to support gross cognitive characterization and to help determine when more comprehensive testing was needed. While TBCA is not meant to replace gold-standard, face-to-face evaluation, if appropriately utilized, it can expand scope of practice, particularly when barriers to standard neuropsychological assessment occur.

Background

The objectives were to characterize Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease 2019 (COVID-19) in patients with acute kidney injury (AKI).

Methods

Kidney biopsy samples in two Caucasian patients and one African with COVID-19 AKI were investigated.

Results

All patients had a high-level non-selective glomerular proteinuria. SARS-CoV-2 samples by real-time polymerase chain reaction (RT- PCR) assay were all-negative, as well as for virus particles in the kidney by electron microscopy. The three patients and patients with other AKI did not differ significantly with regard to angiotensin-converting enzyme 2 and transmembrane protease serine 2 kidney staining.

Conclusions

The kidney damage particularly in Caucasians in COVID-19 seems to be an AKI, possibly by the systemic inflammatory response.
