Breaking down chipping and fragmentation in sediment transport: the control of material strength
Authors: Bodek Sophie , Jerolmack Douglas J. 
Published: December 2021

Abstract. As rocks are transported, they primarily undergo two breakdown mechanisms: fragmentation and chipping. Fragmentation is catastrophic breakup by
fracture in the bulk – either by subcritical crack growth under repeated collisions, or from a single high-energy (supercritical) collision – and
produces angular shards. Chipping is a distinct low-energy mechanism of impact attrition that involves shallow cracking; this process rounds river
pebbles in a universal manner under bed-load transport. Despite its geophysical significance, the transition from chipping to fragmentation is not
well studied. Here, we examine this transition experimentally by measuring the shape and mass evolution of concrete particles of varying strength,
subject to repeated collisions in a rotating drum. For sufficiently strong particles, chipping occurred and was characterized by the following:
attrition products were orders of magnitude smaller than the parent; attrition rate was insensitive to material strength; and particles experienced
monotonic rounding toward a spherical shape. As strength decreased, we observed the onset of a subcritical cracking regime associated with
fragmentation: mass of attrition products became larger and more varied; attrition rate was inversely proportional to material strength; and shape
evolution fluctuated and became non-monotonic. Our results validate conceptual and numerical models for impact attrition: chipping follows
“Sternberg's law” of exponential mass loss through time; for fragmentation, the lifetime of particles increases nonlinearly with material
strength, consistent with “Basquin's law” of fatigue failure. We suggest that bedrock erosion models must be clarified to incorporate distinct
attrition mechanisms, and that pebble or bedrock-channel shape may be utilized to deduce the operative mechanism in a given environment.

Published: December 2021

Introduction. The experience of organization of medical activity in the medical institutions subordinate to the FMBA of Russia in the Siberian Federal District during the I-III epidemic waves of COVID-19, the procedure for making and implementing organization and managerial decisions on building the health care system; the analysis of the experience gained in the formation and operation of consolidated mobile emergency response teams was made.Materials and methods. The study was performed on the basis of the statistical data, regulations on the organization of medical care for patients diagnosed with COVID-19, including medical care provision in the extreme conditions.Results and Discussion. The rational distribution of infectious diseases hospitals, human resources and equipment made it possible to create bed capacity reserve, as a result of which, even during the peak episodes of the pandemic process, the average occupancy of beds in the serviced area was no more than 92-93% and there was always the possibility to receive new patients in hospitals; the capacity of the laboratory was gradually increased 25 times: from 200 tests per day in the pre-pandemic period to 5,000 tests per day. Thanks to the introduction of the new management solutions, digitalization of medical processes has been ensured: accounting of results in the medical information system, transmission of results directly to medical institutions within 12-14 hours, which is 4 times faster than the standard time. The legal regulations of interaction with the rescue centres of the Ministry of Emergency Situations of Russia, the Ministry of Defense and other power structures, the improvement of the material and technical equipment of basic mobile hospitals and emergency medical teams were proposed for discussion.Conclusion. A scheme has been worked out for the involvement of the MOF of the Federal Medical and Biological Agency of Russia in the timely organizational measures for mobilization of forces and means in order to ensure the re-profiling of medical activities to work on providing medical care in the COVID-19 pandemic conditions.
Food allergies and acute allergic reactions: diagnostic options
Authors: Lepeshkova T. S. , Andronova E. V. 
Published: December 2021

Introduction. Anaphylaxis is a systemic potentially life-threatening hypersensitivity reaction featuring the rapid onset, manifestations of the respiratory tract and/or hemodynamics and usually, but not always, accompanied by changes in the skin and mucous membranes [1]. The cause of developing an acute generalized reaction in food anaphylaxis may be the minimum culprit product amount that has entered the patient's body through the mouth or through the skin/mucous membranes. Patients like these are, as a rule, first seen by a paediatrician, a related specialist, or a paramedic. Since the doctors often consider the symptoms of foodborne anaphylaxis separately, the latter does not cause proper suspicion: angioedema and/or acute urticaria accompanying rhinorrhea, acute bronchospasm or laryngitis developed extremely quickly or immediately after contact with an allergen.The aim of the work was to acquaint paediatricians and doctors of related specialties with the food anaphylaxis symptoms, to justify the need for an allergologist-immunologist to consult these patients in order to resolve the issue of required component-resolved diagnosis of allergy and development of an individual elimination diet, taking into account the patient's sensitization profile.Materials and methods. Clinical observation of a child (boy, age — 12 months) with symptoms of atopic dermatitis and episodes of food anaphylaxis in the anamnesis; general clinical examination and allergological examination of the patient by component allergodiagnostics were performed.Results. Sensitization to ovalbumin (Gald 2 -16.60 kU/l) and ovomucoid (Gald 1-9.01 kU/l) was established. The detected sensitization is a predictor of severe systemic allergic reactions to eggs.Discussion. Component diagnostics performed as prescribed by an allergologist not only confirms the causative allergen, but also evaluates the risks of developing acute reactions if the allergen is accidentally introduced to the child and the timing of the patient's tolerance formation. This sensitization will cause sudden systemic allergic reactions for years to come.Conclusion. It is important for a specialist to timely suspect food anaphylaxis, differentiate it from other emergency and urgent conditions, and give the patient the correct recommendations on the need for consultation with an allergologist-immunologist. Only a thoughtful, comprehensive medical approach to each acute condition in a child will significantly reduce the risk of repeated episodes of food anaphylaxis.

Introduction. Despite significant advances in the creation of stable cell lines, the focus of research has recently shifted toward the creation of primary cell cultures derived directly from patient tumor samples, which include both tumor cells and microenvironmental cells.The aim of the study was to compare the morphological characteristics of the cells of a breast carcinoma sample when cultured over three passages.Materials and methods. Material for the study was obtained during surgical intervention in a patient diagnosed with breast carcinoma. Slices were prepared from the tumor sample according to the standard histological protocol and stained with monoclonal antibodies to estrogen, progesterone, Ki-67, Her2/neu receptors. Cell nuclei were stained with hematoxylin. Immunohistochemical reaction was performed in DAKO autostainer (Denmark). Part of the material was placed in Hanks' solution with 5% antibiotic antimycotics and delivered to the Cell Culture Laboratory, where after performing the standard protocol for obtaining cell culture, tumor cells were diluted in Mammocult nutrient medium and placed in culture vials. For morphological evaluation, cells were stained by Pappenheim. For immunocytochemical analysis in determining the belonging of cells to epithelial cells using anti-Pan Keratin Primary Antibody antibody. The number of cells was counted in an automatic TC20 counter, and culture growth was monitored using an Eclipse TS100 microscope, Nikon (Japan).Results and Discussion. On the basis of immunohistochemical study, the tumor sample was classified as Luminal-A subtype. During the study several groups of cells were isolated and cytologically evaluated. The results of immunocytochemical analysis of the cultured cells confirm that the tumor cells retained their epithelial phenotype during culturing. In spite of the manifestation of cell polymorphism in BML cell culture, during three passages the cultured tumor cells retained their epithelial nature and showed a tendency to form a monolayer.Conclusion. A detailed study of cytomorphology and immunocytological characteristics of cultured cells of different immunohistochemical PBMC subtypes will help to evaluate the main regularities of tumor cell vital functions in vitro and allow a more differentiated approach to the creation of personalized cell cultures in order to develop a targeted chemotherapeutic effect on tumors of specific patients.

Published: December 2021

Aim: Breast cancer is the leading cause of death among women around the world. Because of its low cost and the fact that it does not emit hazardous radiation, infrared thermography has emerged as a viable approach for diagnosing the condition in young women. This study aims to create a computer-aided diagnostic system that can process thermographic breast cancer images and classify breast cancer with pre-trained networks in order to use thermography as a diagnostic method.
Materials and Methods: In this study, an open-access data set consisting of thermographic breast cancer images was used for diagnostic purposes. The data set consists of 179 healthy images and 101 images from patients. The images were converted from .txt format to .jpeg format. The data set is acquired from http://visual.ic.uff.br/dmi/. In this study, various pre-trained networks were used to reduce the training time. Different metrics were employed to assess the performance of the models.
Results: The images obtained during the modeling phase were used to display both breasts in the image without distinguishing the right and left breasts, that is, without fragmenting the images. According to the results of the different pre-trained network models after the data preprocessing stages, the best classification performance was achieved for the ResNet50V2 model with an accuracy value of 0.996.
Conclusion: In this study, a computer-aided diagnosis system was created by developing an interface for breast cancer classification from thermographic images in addition to experimental findings. The web software based on the proposed models has provided promising predictions of breast cancer from thermographic images. The developed software can help medical and other healthcare professionals easily spot breast cancer.
Genetically Modified Crops and Gender Relations in Low-and Middle-Income Countries: A Critical Review
Authors: Schnurr Matthew A. , Addison Lincoln , Bawa Sylvia , Gore Christopher 
Published: December 2021

Abstract
Since their release in the early 1990s, genetically modified (GM) crops have been lauded as a tool to redress stagnating yields and food insecurity among poor farmers. The potential for GM crops to alleviate poverty for farmers in low- and middle-income countries (LMICs) will likely hinge on their ability to enhance women’s overall well-being, yet there is little research that evaluates if (and how) the technology has such transformative potential. This article reviews the existing scholarship on this topic by grouping it into three strands: (1) the impacts of GM crops on labor processes, (2) gender and patterns of adoption, and (3) the consequences of GM crops for intra-household gender relations. Each area is characterized by contradictory findings, reflecting the diversity and complexity of gender relations in different contexts. Our review suggests that further research should build on mixed-method approaches that involve long-term interactions with households in order to generate robust and gender-disaggregated data that yield nuanced, context-specific analysis.
Parsing the Concepts and Practices of Gender, Development Disaster, and Climate Change: Visions of Transformation
Authors: Tickamyer Ann R. 
Published: December 2021

Abstract
Concepts used to understand and analyze two closely related fields—gender and development and gender, disaster, and climate change—overlap in the ways gender is implicated and women are targeted. This article explores the overlapping conceptual language that characterizes these fields to demonstrate how they emerge from feminist scholarship and converge in the project to promote social change for the realization of human rights for women. Terms like equality, mainstreaming, empowerment, resilience, agency, sustainability, and transformation permeate the research and policy literatures produced by both fields. Each field has moved from a sole focus on women to a broader understanding of the relational systems that bind women’s and men’s fortunes in both development and disaster/climate change with an emphasis on the role of power structures and hierarchies from local to global levels. Both fields increasingly adopt an intersectional approach that analyzes the complexities created by multiple social locations and identities. Gender and development explores the inequalities that disadvantage and marginalize women in the Global South across different social and geographic locations. Gender, disaster, and climate change similarly demonstrates the differential risks, vulnerabilities, and opportunities for recovery from disaster and adaptation and management of climate change that gender creates. Both use feminist epistemology and theory that combine reflexivity and advocacy with situated knowledge in analysis. Recognizing that their overlapping conceptual frameworks converge contributes to relevant research and policy analysis promoting social change and human rights. Examples are drawn from primary and secondary research in Indonesia to illustrate.

PURPOSE. To evaluate the efficacy and safety of repeated micropulse transscleral cyclophotocoagulation (MP-TSCPC) in patients with previously operated refractory glaucoma.MATERIALS AND METHODS. We examined 89 patients aged 74.2±7.3 years with moderate (16), advanced (58) and terminal (15) stages of uncompensated primary openangle glaucoma (POAG) before and within 12 months after the first MP-TSCPC (SUPRA 810, “Quantel Medical”, France) using standard laser parameters — 100 J. Indications for repeated MP-TSCPC were determined for 23 patients in 3 (1 patient), 6 (14 patients), 9 (8 patients) months after the first procedure. Repeated MP-TSCPC was carried out with higher impact energy — 125 J.RESULTS. After the first procedure, the hypotensive effect was achieved in 66 (74.2%) patients with refractory glaucoma lasting up to 12 months of follow-up. Repeated MP-TSCPC in 23 patients reduced the IOP by 31.2% in moderate, 31.8% in advanced, and 22.9% in terminal stages (p<0.05) by 6 months of follow-up. As a result, during 12 months of observation, MP-TSCPC (single and double) led to stabilization of the IOP in 83.1% of cases.CONCLUSION. Single and repeated micropulse TSCPC with laser energies of 100 J and 125 J is an effective and safe method of treating patients with refractory glaucoma. A single MP-TSCPC with laser energy of 100 J was effective in 66 (74.2%) patients by 12 months of observation, and single followed by repeated (laser energy of 125 J) — in 74 (83.1%) patients. It is possible to revise the basic parameters of the MP-TSCPC procedure from 100 to 125 J to achieve a longer and at the same time safe hypotensive effect in patients with refractory glaucoma.

De dynamiek van sluipende crises: meekoppelen van klimaatbeleid met besluiten van vandaag
Authors: de Gooyert Vincent , de Coninck Heleen 
Published: December 2021

On the dynamics of creeping crises: Coupling climate policies with today’s decisions
Addressing a creeping crisis like climate change requires nothing less than a system transition. A system transition is very complex and hence its success depends to a large extent on feedback effects: mechanisms where an initial change reinforces itself or balances itself out. Urgent crises are more salient than creeping crises. However, it is possible to combine policies for both urgent and creeping crises, as can be seen in policies that aim for a green recovery. In this article, we conclude that up till now such policies have overlooked the relevance of feedback effects. We provide examples of corona recovery measures that simultaneously help to establish a system transition through feedback effects.
