AbstractEnvironmental factors shape the structure and functioning of benthic communities. In coastal zones of the southwestern Baltic Sea, boulder fields represent one of the most productive habitats, supporting diverse benthic communities that provide many ecosystem services. In this study, the influence of the geological characteristics of boulder fields on the biodiversity of associated hard-bottom communities was investigated at two different spatial scales (few kilometers and tens of kilometers). The analyses on overall richness (taxonomic and functional) and community composition revealed how: (i) locally the size of boulders and (ii) regionally site-specific factors like the boulder density distribution and the sediment distribution can act as environmental driving forces. The overall richness of assemblages was shown to increase with increasing surface area of boulders, by up to 60% for species and up to 40% for functional richness. At both investigated scales, differences in compositional variability (β diversity) of the communities were detected. Locally, smallest boulders hosted more variable communities (β diversity up to 2 times higher), while at the regional level, indications of a larger habitat heterogeneity featuring the highest β diversity were observed. This study exemplifies how geological habitat characteristics shape the biodiversity of boulder field communities. The obtained information could be considered in assessment strategies, in order to avoid misclassifications of habitats naturally limited in biodiversity, making a step forward to the desired objective of protecting, conserving, and managing boulder field communities in the study area and at other comparable sites.

Published: February 2021

AbstractVacuum cooling of baked goods can deliver many advantages in terms of product quality and productivity, such as higher volumes and shorter cooling times. However, the associated high costs and the need to adjust baking protocols are of relevance and more information is needed. This paper examines the influence of two main baking protocol parameters on the quality of toast bread, i.e. oven temperature and baking time reduction. Resulting toast bread characteristics including specific bread volume, concavity, browning index, crust and crumb hardness and aw-value were analysed as well as process-dependent core temperature and water loss. In order to compensate for water loss during vacuum cooling and still achieve optimal toast bread quality, a final bread core temperature of 98 °C at the end of baking gave best results, regardless of oven temperature. It was further shown that cooling time can be reduced by a factor of 10 if the baking protocol is optimally adjusted, hinting at a huge potential to increase productivity for industrial applications. In summary, it can be stated that vacuum cooling requires a tailored reduction in baking time in order to compensate for water loss from vacuum cooling while retaining sufficient structural cohesion to resist deformation of the bread.
Co-design of experimental nature-based solutions for decentralized dry-weather runoff treatment retrofitted in a densely urbanized area in Central America
Authors: Pérez Rubi Maria , Hack Jochen 
Published: February 2021

AbstractThe quality of water in many urban rivers in Latin America is increasingly degrading due to wastewater and runoff discharges from urban sprawl. Due to deficits in sanitary drainage systems, greywater is discharged to the stormwater drainage network generating a continuous dry-weather runoff that reaches rivers without treatment. One of the main challenges in the region is to achieve sustainable management of urban runoff for the recovery of rivers ecosystem integrity. However, retrofitting conventional centralized wastewater drainage networks into the existing urban grid represents important social, economic and technical challenges. This paper presents an alternative adaptive methodology for the design of Nature-based Solutions for decentralized urban runoff treatment. Through this study, technical solutions commonly used for stormwater management were adapted for dry-weather runoff treatment and co-designed for the particular conditions of a representative study area, considering space availability as the main constraining factor for retrofitting in urban areas. The application of a co-design process in a dense neighbourhood of the Great Metropolitan area of Costa Rica brought to light valuable insights about conditions that could be hindering the implementation of NBS infrastructures in Latin America.
Gene flow and reproductive success in ash (Fraxinus excelsior L.) in the face of ash dieback: restoration and conservation
Authors: Semizer-Cuming Devrim , Chybicki Igor Jerzy , Finkeldey Reiner , Kjær Erik Dahl 
Published: February 2021

Abstract

• Key message

Ash dieback decreases individual reproductive success of ash trees leaving healthy ash overrepresented as seed and pollen parents for next-generation seedlings. Substantial gene flow over hundreds of meters combined with superior fertility of healthy trees creates optimism for the species’ future in European forests.

• Context

Hymenoscyphus fraxineus is causing high mortality in European ash (Fraxinus excelsior L.). Due to inheritable resistance to the pathogen, natural selection is likely to act in favour of improved resistance in ash forests following natural regeneration. Still, the frequency of healthy trees is low, and the effect of natural selection will depend on survival, reproductive success and the dispersal capacity of healthy trees under natural conditions.

• Aims

We aim to test whether healthy trees contribute more to the next generation and to infer their potential for dispersing progenies across the forested landscape.

• Methods

Using parentage modelling, we estimate mating parameters and dispersal distances of seeds and pollen and compare realised reproductive success of healthy trees to that of unhealthy ones.

• Results

Healthy trees are overrepresented as the parents of randomly sampled seeds and seedlings in the forest, although that is more pronounced on the female side. We observe long dispersal events and estimate the mean seed and pollen dispersal distances as 67 m and 347 m, respectively.

• Conclusion

Variation in reproductive success results in selection in favour of lowered susceptibility to ash dieback. The large dispersal capacity decreases the risk of genetic bottlenecks and inbreeding and allows resistant trees to disperse their genes into the neighbourhoods of substantial sizes.

Abstract
Introduction
Fluorine-18 (18F) Fluciclovine (anti-1-amino-3-18F-fluorocyclobutane- 1-carboxylic acid [FACBC]) is a synthetic amino acid labeled with 18F, currently used as PET radiopharmaceutical to investigating prostate cancer, namely in the recurrent setting.
Fluciclovine is transported to cell membranes by amino acid transporters, such as LAT1 and ASCT2. The upregulation of LAT-1 and ASCT2 activities is typical of prostate cancer but is also present in other pathological conditions such as non-prostatic neoplasms (e.g., lung cancer) and in benign inflammatory process (e.g., benign prostatic hyperplasia, chronic prostatitis, high-grade prostatic hyperplasia intraepithelial).

Methods
In this short essay we present a retrospective FACBC PET/CT analysis consisting of a selection of the five most relevant cases of patients referred in our centre to FACBC PET/CT for prostate cancer, with concomitant FACBC uptake in sites atyipical for prostate cancer.

Results
These five selected cases demonstrate FACBC uptake at the level of the pancreatic head, adrenal incidentalomas, pulmonary nodules, mediastinal lymph nodes and neoformative tissue of the rectal wall.

Discussion
Clinical cases selected in this pictorial essay have demonstrated that Fluciclovine is not an exclusive and specific radiotracer for prostate cancer and, therefore, can induce misdiagnosis. In fact, incidental benign and malignant uptake might occur and should be further evaluated with clinical correlation or other imaging.
‘TRAP-ped with an Acardius’: Case Series of Twin Reversed Arterial Perfusion (TRAP) Sequence and Review of Literature
Authors: Quaas Philipp , Markfeld-Erol Filiz 
Published: February 2021

AbstractTwin reversed arterial perfusion (TRAP) sequence is a rare but severe condition that affects monochorionic (MC) multifetal pregnancies. In twin pregnancies, it is characterized by a normally developed twin and another twin with missing heart function (acardiac twin or TRAP twin). A variety of risks and complications may affect the normal twin. Management of such pregnancies can be either expectant or interventional. We report four cases of TRAP sequence treated in our institutions and supply an overview on currently existing literature. This case series demonstrates the heterogeneity in manifestations and clinical course of patients affected by this condition. Furthermore, it includes an acardius amorphous of considerable size delivered at 35.6 weeks of gestation.
Testicular Adrenal Rest Tumours: fisiopatologia, diagnosi e trattamento
Authors: De Alcubierre Dario , Pofi Riccardo , Pozza Carlotta 
Published: February 2021

SommarioI testicular adrenal rest tumors (TARTs) costituiscono una causa comune di disfunzione gonadica e infertilità in pazienti affetti da iperplasia surrenalica congenita (Congenital Adrenal Hyperplasia, CAH), con una prevalenza che varia dal 14 all’86%. Dal punto di vista biochimico, istologico e molecolare, i TARTs mostrano caratteristiche tipiche delle cellule surrenaliche e per questo si è ipotizzato che derivino da una proliferazione di cellule della corteccia surrenalica in sede testicolare. Studi recenti riconducono però l’origine dei TARTs a una popolazione di cellule staminali pluripotenti adrenal-like, derivanti dalla cresta urogenitale, già presenti in sede gonadica durante l’embriogenesi, che vanno incontro a differenziazione surrenalica e ad aumentata proliferazione se sottoposti a elevati livelli di ormone adrenocorticotropo (ACTH). La loro crescita può determinare un’alterazione della funzione gonadica per compressione diretta sui tubuli seminiferi e per l’influenza sull’ambiente ormonale intratesticolare per via paracrina, risultando spesso in un quadro di azoospermia di tipo ostruttivo. La diagnosi di TARTs si avvale principalmente dell’eco Color-Doppler testicolare, ma richiede una puntuale diagnosi differenziale con lesioni morfologicamente simili, quali i tumori germinali e i tumori a cellule del Leydig, in quanto la gestione terapeutica è differente. La terapia classica si basa sull’impiego di glucocorticoidi ad alte dosi, che in alcuni casi possono condurre a una regressione delle dimensioni della massa. La gestione della CAH nei soggetti che presentano TARTs richiede un approccio personalizzato con screening ecografico da adottare già a partire dall’infanzia e si avvale altresì di counseling andrologico in merito alla possibilità di preservare la fertilità tramite crioconservazione.
In situ stress measurement and analysis of the stress accumulation levels in coal mines in the northern Ordos Basin, China

AbstractFor non-directional drilling cores, selection of samples and the test methods for in situ stress measurements to evaluate the Kaiser effect (KE) were proposed, and the magnitude and direction of the principal stresses were derived from first principles. Based on this approach, the KE for 423 samples in the Burtai and Baode coal mines in the northern Ordos Basin (NOB), China, have been investigated. The results show that the maximum horizontal principal stress (σH), the minimum horizontal principal stress (σh) and the vertical stress (σv) varied with depth and location, and the values increase with increasing depth. Generally, the horizontal stresses play a leading role. For the main stress regimes in the NOB, σH > σh > σv (Burtai Mine, < 172 m; Baode Mine, < 170 m) and σH > σv > σh (Burtai Mine, 170–800 m; Baode Mine, 170–400 m), and the σv > σH > σh stress regimes are mainly distributed in moderately deep to deep coal mines. For rock masses with a depth of 350 m, k ((σH + σh)/2σv) tends to 1, indicating that a deep critical state will gradually emerge. The test results are compared with those for the overcoring (OC) method, the anelastic strain recovery (ASR) method and micro-hydraulic fracturing (HF). The relative errors for σH, σh and σv were 14.90%, 19.67%, 15.47% (Burtai Mine) and 10.74%, 22.76%, 19.97% (Baode Mine), respectively, and the errors are all within an acceptable range, thus verifying the reliability of the KE method. The dominant orientation for the σH (Burtai mine, NE-NNE; Baode Mine, NEE) is obtained via paleomagnetic technology, and the data are consistent with those (NE-NEE) of the earthquake focal mechanism solutions for the area. Based on the Byerlee–Anderson theory, a discussion is given on the levels of stress accumulation in the rock mass of the mines. For dry rocks or hydrostatic pressure rocks, the friction coefficients of the faults are low for both locations, and the values are less than the lower limit (0.6) of the strike-slip faults slip, indicating that the stress fractures at a low level around the study areas are lower than the friction limit stress. The stress accumulation levels in the Baode Mine are slightly larger than those in the Burtai Mine.

Published: February 2021

AbstractThis research demonstrates the effect of some amide compounds (1 and 2) as corrosion inhibitors on C-steel in 1.0 M of hydrochloric solutions utilizing mass reduction studies, electrochemical [potentiodynamic (PP), AC impedance measurements (EIS), electrochemical frequency modulation] techniques, and surface checks were used to illustrate the importance of amide compounds to the corrosion protection process of C-steel. The tests displayed that the inhibition efficiency (IE%) augmented with increase in amide dose but reduced with growth of temperature. The highest inhibition efficiency is 99% for compound (1) and 98.8% for compound (2) at maximum dose tested (50 µM) by polarization method. PP data show that these compounds affect both cathodic and anodic processes (i.e. mixed type) and were adsorption on the carbon steel obeying Langmuir adsorption isotherm. The EIS results indicate that the changes in impedance parameters are related to the adsorption of amides on the alloy surface. Scanning of electron microscopy, energy transmitted X-ray—Atomic force microscopy studied the morphology of inhibited C-steel.Graphic abstract

Published: February 2021

AbstractWhile Ethiopia has six species of stingless bees, indigenous knowledge of them has not been well documented. In southwestern Ethiopia, we documented the Sheka community’s knowledge of stingless bees. We used the snowball sampling technique to locate 60 experienced honey collectors, conducted semi-structured interviews, and complemented interviews with field observations during honey collection trips with interviewees. Given the scarcity of aboveground nesting stingless bees, honey collectors only collected honey from stingless bees nesting belowground. The average age of the honey collectors was 43 years, but there was much variation in both age and the number of years of experience, indicating that the tradition is handed down between generations. To find the underground nests in the field, honey collectors used several methods, including directly observing nest entrances and worker bee movement, attaching a thread to the worker bee, and listening for the humming sound of the bee’s natural enemy (wasp). Wild nests were always harvested destructively. A single farmer kept ground-nesting stingless bee colonies at his backyard using uniquely tailored wooden hives. Collected honey was used for home consumption, disease treatment, and the generation of income. Our findings illustrate the Sheka community’s deep indigenous knowledge of ground-nesting stingless bees. To facilitate the establishment of stingless bee beekeeping (meliponiculture) in the study area, we may build upon this indigenous knowledge by field research on the biology of stingless bees, taxonomic studies to assess the diversity and identity of ground-nesting stingless bees, and engineering studies to develop beekeeping practices. Together, this may allow for better income for local farmers and avoid the risk of overexploitation of wild stingless bee nests.
Cash transfers, climate shocks vulnerability and households’ resilience in Togo
Authors: Sodokin Koffi , Nyatefe Victor 
Published: February 2021

AbstractThis paper uses data from the survey of basic wellbeing indicators (2015) to investigate climate-related risk perceived impact on the household’s living standard in Togo. We investigate the data using a subjective approach with a Probit model and a Propensity Score Matching Method. For the majority of households in the sample, the results suggest, on the one hand, a significant impact of climate-related risk on their living standards. On the other hand, the estimation results show that income from activities increases the resilience and reduction of Togo households' climate-related effects. Finally, remittances increase the households' ability to be less climate vulnerable and play a significant role in the household’s resilience building. In terms of public policies, the results imply that a broader consultation and strategy are needed to reduce the consequences of climate related-risks on households in Togo.
Thirty years of design for sustainability: an evolution of research, policy and practice
Authors: Bhamra Tracy , Hernandez Ricardo J. 
Published: February 2021

AbstractThis paper builds on the lead author’s keynote address to the Design Society’s 22nd International Conference on Engineering Design in 2019, and in doing so provides a personal perspective on the development of the field of design for sustainability. It begins by describing some of the history of the research from the late 1980s until the present day. This is followed by an analysis of the way in which design for sustainability has been reflected within the International Conference on Engineering Design over the last 30 years, highlighting the way in which the focus has shifted over this time from a focus on recycling and end of life to today where sustainability is playing a leading role in the research. The analysis compares the evolution of the subject with the wider policy and practice perspectives linked to global recognition of the need to move towards Sustainable Development. Finally, the paper reflects on the lessons to be learned from this work and their implications for design research illustrating that engineering design has an opportunity to take more leadership within design for sustainability research and use this to enable change within industry.

AbstractObjective:Candida auris infections continue to occur across the United States and abroad, and healthcare facilities that care for vulnerable populations must improve their readiness to respond to this emerging organism. We aimed to identify and better understand challenges faced and lessons learned by those healthcare facilities who have experienced C. auris cases and outbreaks to better prepare those who have yet to experience or respond to this pathogen.Design:Semi-structured qualitative interviews.Setting:Health departments, long-term care facilities, acute-care hospitals, and healthcare organizations in New York, Illinois, and California.Participants:Infectious disease physicians and nurses, clinical and environmental services, hospital leadership, hospital epidemiology, infection preventionists, emergency management, and laboratory scientists who had experiences either preparing for or responding to C. auris cases or outbreaks.Methods:In total, 25 interviews were conducted with 84 participants. Interviews were coded using NVivo qualitative coding software by 2 separate researchers. Emergent themes were then iteratively discussed among the research team.Results:Key themes included surveillance and laboratory capacity, inter- and intrafacility communication, infection prevention and control, environmental cleaning and disinfection, clinical management of cases, and media concerns and stigma.Conclusions:Many of the operational challenges noted in this research are not unique to C. auris, and the ways in which we address future outbreaks should be informed by previous experiences and lessons learned, including the recent outbreaks of C. auris in the United States.
The Migrant Other: Exclusion without Nationalism?
Authors: Schenk Caress 
Published: February 2021

AbstractMigrants are an easy, visible Other, seeming to fall neatly into the us-versus-them framework of nationalism. Nevertheless, much of the scholarly approach to migrant identity, with the partial exception of a largely separate literature on citizenship, has eschewed overt ties to nationalism studies. When us-versus-them language is used in relation to nationalism, the focus or nodal point is the identity of the seemingly homogenous “us” of the nation. However, when migrants are othered, the focus is not always the nation, and while othering migrants always creates exclusion, it is not always exclusion from a nation or identity group. This state of the field article analyzes the literature on populism, securitization, biopolitics, and other critical scholarship related to the issue of othering migrants. In each of these bodies of work, different sets of “us” are set against migrants, some of which evoke identity and others of which do not, elucidating the links (or the lack thereof) of each approach to the study of nationalism. In each of these frameworks, the migrant Other comes up against a different frame of reference, leaving migrants themselves (or any sense of migrant identity) somewhat lost amid the analytical frameworks, at continual risk of being re-othered as victims of circumstance without agency.
