Planetary radar science case for EISCAT 3D
Authors: Tveito Torbjørn , Vierinen Juha , Gustavsson Björn , Narayanan Viswanathan Lakshmi 
Published: May 2021

Abstract. Ground-based inverse synthetic aperture radar is a tool that can provide insights into the early history and formative processes of planetary bodies in the inner solar system.
This information is gathered by measuring the scattering matrix of the target body, providing composite information about the physical structure and chemical makeup of its surface and subsurface down to the penetration depth of the radio wave.
This work describes the technical capabilities of the upcoming 233 MHz European Incoherent Scatter Scientific Association (EISCAT) 3D radar facility for measuring planetary surfaces.
Estimates of the achievable signal-to-noise ratios for terrestrial target bodies are provided. While Venus and Mars can possibly be detected, only the Moon is found to have sufficient signal-to-noise ratio to allow high-resolution mapping to be performed.
The performance of the EISCAT 3D antenna layout is evaluated for interferometric range–Doppler disambiguation, and it is found to be well suited for this task, providing up to 20 dB of separation between Doppler northern and southern hemispheres in our case study.
The low frequency used by EISCAT 3D is more affected by the ionosphere than higher-frequency radars. The magnitude of the Doppler broadening due to ionospheric propagation effects associated with traveling ionospheric disturbances has been estimated.
The effect is found to be significant but not severe enough to prevent high-resolution imaging.
A survey of lunar observing opportunities between 2022 and 2040 is evaluated by investigating the path of the sub-radar point when the Moon is above the local radar horizon.
During this time, a good variety of look directions and Doppler equator directions are found, with observations opportunities available for approximately 10 d every lunar month.
EISCAT 3D will be able to provide new, high-quality polarimetric scattering maps of the nearside of the Moon with the previously unused wavelength of 1.3 m, which provides a good compromise between radio wave penetration depth and Doppler resolution.

Discussion—Stillwater, Montana Chromite Deposits
Authors: Sampson Edward 
Published: May 2021

Abstract
Edward Sampson. In discussing Mr. Jackson's paper I should like to make a few remarks concerning mainly the Mountain View area. Before 1930 the group of rocks now known as the Stillwater complex has been described (Westgate, 1922) as an intrusive dike or sill invading a Precambrian complex and of Laramide age. In 1930 I recognized it as a complex closely similar to the Bushveld complex. Mr. Peoples and Mr. Howland, then graduate students at Princeton University, were assigned to work on the complex for doctoral dissertations. In 1936 a brief account (Howland et al., 1936) was published. Work continued until the outbreak of World War II under great difficulties as no adequate maps were available. A number of chemical analyses of carefully cleaned chromites were made. Then all information of Princeton University was turned over to the U. S. Geological Survey and Peoples and Howland joined the Survey staff.
Clearly crystal settling within the magma chamber is the controlling process (Fig. 1), although in certain places irregular intrusive relations are found as shown in Figure 2.
Experimental Investigations of Chromite Spinels
Authors: Ulmer Gene C. 
Published: May 2021

Abstract
The techniques of oxygen-fugacity buffering have recently been applied to several ternary and quaternary systems for the purpose of studying the stability and extent of chromite spinel solid solutions. Examination of data at the subsolidus temperature of 1,300° C provides an insight into the phase relationships among the six spinel end-members: Magnesioferrite (MgFe2O4), Spinel (MgAl2O4), Picrochromite (MgCr2O4), Magnetite (Fe3O4), Hercynite (FeAl2O4), and Chromite (FeCr2O4). The phase equilibria data indicate that while complete solid solution among these spinels does exist at 1,300° C, the solid solutions may involve defect spinels that contain trivalent ions in excess of the 1:2 divalent to trivalent ratio. A summary of the spinel data shows that, at one atmosphere and 1,300° C, oxygen fugacities in the range of 10–5 to 10–7 atm are necessary to form the range of compositions observed for natural spinels.
Liquidus studies of the effects of oxygen fugacity on fractional crystallization are reviewed for the systems MgO-FeO-Fe2O3-SiO2 and MgO-CaO-SiO2-iron oxide and MgO-FeO-Fe2O3-CaAl2Si2O8-SiO2. These liquidus data are interpreted to show that both temperature and oxygen fugacity are important variables in the petrogenesis of chromite-silicate sequencs. It is hypothesized that variations in oxygen fugacity in the parent magma can control cyclic crystallization as well as compositional variations of the spinel and silicate layers of chromite deposits.
Fennoscandian Nickel Deposits
Authors: Haapala P. S. 
Published: May 2021

Abstract
This paper mainly concerns the active fields of Petsamo (Pechenga), Monchegorsk, and Kotalahti.
The Petsamo deposits are associated with a zone of layered intrusions that lie within low-metamorphic volcanics and sediments framed by gneisses. The orebodies, which adhere to the footwall of the intrusions, are comprised of disseminated sulfides in serpentinite, many with underlying massive sulfides. With increasing deformation, ore breccias gain in importance and the mineralization extends into adjacent phyllites. The pattern, composition and distribution of the sulfidic phase and its species, reflect local conditions.
The Monchegorsk mineralization lies in layered ultrabasics underlain by gneisses. The sulfides occur as disseminations, massive veins, and minor bodies. The veins strike parallel with, and are grouped above, the long axis of the massif, dip across the layering and die out before reaching the base. Dike rocks traversing the massif are cut by veins.
The Kotalahti orebodies are mineralized portions of complex basic units encased in steeply dipping gneisses. Pegmatitic and amphibolitic bodies traverse the gneisses and brecciate the ore-bearing masses. Orebodies consist of an intricate mixture of disseminated perknite, peridotite and gabbro, and barren pegmatitic and amphibolitic matter, superimposed on which are bodies and stringers of massive sulfides. One exception is an ore shoot entirely enclosed in schists without any apparent connection to basic units.

Erosion Control Success Stories and Challenges in the Context of Sustainable Landscape Management, Rwanda Experience
Authors: Rutebuka Jules 
Published: May 2021

The Government of Rwanda sets up a conducive policy environment to invest in several development initiatives. Agriculture sector as the main contributor in the economic development received supports to sustainably manage Rwandan hilly landscape, dominantly ranging from 5 to 55% slope gradient. Intensive erosion control interventions confronted with different approaches have been introduced in the country such as participatory landscape management, (participatory) integrated watershed management and site-located intervention without any specified approach. This chapter intends to describe and evaluate the impacts of these previous approaches used in Rwanda in order to retrieve the success stories and encountered challenges as lessons learnt in the future interventions for optimizing land productivity in a sustainable manner. Participatory landscape approach in Gishwati area was a success story in protecting degraded lands and generating ecosystem benefits. It leads to more sustainable natural resources management from participatory planning up to implementation which addressed the frequent landslides, erosion and flooding while sustainably exploit the land to the profit of local farmers in the livelihoods. About 6,600 ha of lands have been successfully protected with full-packaged bench terraces, rangeland blocks and forest regeneration. This participatory approach also helped to relocate people from high risk zones to other safe places and build capacities of farmers through farm-livestock cooperatives. On the other side, Nyanza and Karongi sites under LWH project also emphasized strong evidences how land husbandry technologies (terraces) efficiently reduced erosion risks and improved farmers’ livelihoods. Lands were made productive with implementation of bench terraces on 3212 and 2673 hectares respectively for the two selected sites. However, challenges were observed from technical and socio-economic contexts which might have caused farmers to abandon or under-exploit the terraced lands. Finally, the chapter suggests to scale up the participatory landscape management approach which supports the involvement of farmers’ communities in the process.
RANSE Calculation of Laminar-to-Turbulent Transition-Flow around Sailing Yacht Appendages
Authors: Böhm Christoph , Graf Kai 
Published: May 2021

A new method to simulate laminar-turbulent transition has been used to study flow around sailing yacht appendages. Based on an empirical correlation, the method allows to predict transitional flow in a fully 3Denvironment using unstructured grids and massive parallelization. Reynolds number of the flow around the appendages of sailing yachts is of an order where transitional flow plays an important role. The method thus serves as a highly valuable tool for realistic optimisation of yacht appendages.
The paper describes briefly Menters γ-ReΘtransition-model and shows its validity for the given purpose. 2D-analysis of NACA-profiles has been chosen to validate the transition model. The resulting lift and drag coefficients from the RANSE calculations have been compared with experimental data and results from the 2Dboundary layer code XFoil, showing reasonable agreement. The method then has been used for a bulb length optimisation of an appendage configuration of an ORC GP42 level racer. Here the differences between a fully turbulent and a laminar turbulent optimisation are shown and discussed.
Response of Escherichia coli minimal ter operon to UVC and auto-aggregation: pilot study
Authors: Jánošíková Lenka , Pálková Lenka , Šalát Dušan , Klepanec Andrej , Soltys Katarina 
Published: May 2021

Aim
The study of minimal ter operon as a determinant of tellurium resistance (TeR) is important for the purpose of confirming the relationship of these genes to the pathogenicity of microorganisms. The ter operon is widespread among bacterial species and pathogens, implicated also in phage inhibition, oxidative stress and colicin resistance. So far, there is no experimental evidence for the role of the Escherichia coli (E. coli) minimal ter operon in ultraviolet C (UVC) resistance, biofilm formation and auto-aggregation. To identify connection with UVC resistance of the minimal ter operon, matched pairs of Ter-positive and -negative E. coli cells were stressed and differences in survival and whole genome sequence analysis were performed. This study was aimed also to identify differences in phenotype of cells induced by environmental stress.

Methods
In the current study, a minimal ter operon(terBCDEΔF) originating from the uropathogenic strain E. coli KL53 was used. Clonogenic assay was the method of choice to determine cell reproductive death after treatment with UVC irradiation at certain time intervals. Bacterial suspensions were irradiated with 254 nm UVC-light (germicidal lamp in biological safety cabinet) in vitro. UVC irradiance output was 2.5 mW/cm2 (calculated at the UVC device aperture) and plate-lamp distance of 60 cm. DNA damage analysis was performed using shotgun sequencing on Illumina MiSeq platform. Biofilm formation was measured by a crystal violet retention assay. Auto-aggregation assay was performed according to the Ghane, Babaeekhou & Ketabi (2020).

Results
A large fraction of Ter-positive E. coli cells survived treatment with 120-s UVC light (300 mJ/cm2) compared to matched Ter-negative cells; ∼5-fold higher resistance of Ter-positive cells to UVC dose (p = 0.0007). Moreover, UVC surviving Ter-positive cells showed smaller mutation rate as Ter-negative cells. The study demonstrated that a 1200-s exposure to UVC (3,000 mJ/cm2) was sufficient for 100% inhibition of growth for all the Ter-positive and -negative E. coli cells. The Ter-positive strain exhibited of 26% higher auto-aggregation activities and was able to inhibit biofilm formation over than Ter- negative strain (**** P < 0.0001).

Conclusion
Our study shows that Ter-positive cells display lower sensitivity to UVC radiation, corresponding to a presence in minimal ter operon. In addition, our study suggests that also auto-aggregation ability is related to minimal ter operon. The role of the minimal ter operon (terBCDEΔF) in resistance behavior of E. coli under environmental stress is evident.
Effectiveness of a clinical decision-support tool on adherence to prescribing and practice guidelines of high-risk antidepressant medications in geriatric patients
Authors: VanDaele Madeline A. , Smith Jordan O. , Franck Jessica Bovio 
Published: May 2021

Abstract

Introduction
TCAs and paroxetine, a SSRI, are associated with safety risks in geriatric patients because of anticholinergic properties. The purpose of this project was to evaluate the impact of a clinical decision-support tool (CDST) on adherence with medication prescribing and practice guidance to enhance patient safety.

Methods
Mental health clinical pharmacy specialists and clinical pharmacy leadership led a multidisciplinary creation and integration of a CDST within a Veterans Health Administration EHR. The CDST focused on the following elements when prescribing TCAs and paroxetine in geriatric patients: clinical justification for initiation of the medication, provision of patient/caregiver education specific to the medication prescribed, evaluation of comprehension of education provided, medication reconciliation, and follow-up completed within 30 days of medication initiation. Following activation of the CDST in the EHR, measures were evaluated before intervention and after intervention.

Results
After intervention, an increase was observed in the primary outcome of the proportion of patients having documentation of all of the following: clinical justification for medication initiation, provision of patient/caregiver education, evaluation of comprehension of education provided, medication reconciliation, and follow-up completed within 30 days of medication initiation (P = .01). Individual proportions of patients with documented medication reconciliation and follow-up completed within 30 days significantly increased. All other secondary outcomes numerically increased but did not reach statistical significance.

Discussion
Improvement was seen in adherence with prescribing and practice guidance following the implementation of the CDST. This suggests the beneficial role of CDSTs within the EHR to optimize patient safety.

AbstractElevated intraocular pressure (IOP) is the leading cause of glaucoma. As glaucoma is an irreversible neurological eye disease, it is urgent to realize timely and accurate IOP detection for diagnostic and therapeutic purposes. Here, a contact lens sensor for continuous IOP monitoring using self‐assembly graphene (SAG), is developed. The combination of face‐to‐face water transfer printing and micro‐electromechanical systems technology can realize the batch preparation of such a sensor. The sensor has good light transmittance and temperature stability. It exhibits an ultra‐high IOP sensitivity of 1.0164 mV mm Hg−1 on a silicone eye, and 3.166 mV mm Hg−1 in vitro on the porcine eye with remarkable linearity. The sensitivity of the proposed sensor is high enough to be read by a commercial radio frequency identification read–write system for continuous wireless monitoring of IOP. Furthermore, the as‐prepared sensor can work as normal for 24 h in phosphate buffer saline.
