Chemical looping combustion of solid fuels using manganese-based oxygen carriers - investigations in 10 and 100 kW pilots

According to climate simulations, the predicted carbon budget to keep global warming below 1.5°C with high certainty will be used up in 2021, assuming 2017 emissions. As an emissions overshoot seems inevitable, bioenergy with carbon capture and storage (BECCS) has been proposed as a means of removing CO2 from the atmosphere in the future. This is done by utilizing biomass in combustion processes and storing the resulting CO2 in underground geological formations such as aquifers or depleted oiland gas fields, thus rendering the total net emissions of CO2 negative. While first generation CCS technologies rely on energy-intensive active gas separation, chemical looping combustion (CLC) can omit that step by utilizing solid metal oxide particles to transfer oxygen from combustion air to fuel, making CO2 capture inherent to the process and avoiding thermodynamic energy penalties. A key research issue is to find oxygen carriers which perform satisfactorily with respect to fuel conversion and lifetime. Manganese materials are promising candidates from a thermodynamic point of view, potentially cheap and environmentally benign, but have previously been challenged with lifetime issues. The aim of this work is therefore to find and test manganese-based oxygen carrier materials with good conversion properties and high durability and to identify the process parameters influencing gas conversion and particle lifetime. To do so, the performance of six different oxygen carrier materials was investigated in continuous 10 kW and 100 kW pilots using both fossil and biomass fuels. Performance – with respect to fuel conversion – of all oxygen carriers was higher than that of the state-of-the-art material, i.e. ilmenite. Manufactured materials generally performed better and had a higher lifetime than that of natural materials, an advantage which in utility scale would have to be weighed against their higher cost. The results suggest that manganese materials, both manufactured and of natural origin, can be a feasible, efficient and cost-effective alternative as oxygen carrier in chemical looping combustion.
Massive Primordial Black Holes

A review of the astronomical data of several last years on an astonishingly high amount of black holes in the contemporary and early ($z\sim 10$) universe is presented. Also the data on the recently observed peculiar stars in the Galaxy are discussed. It is argued that practically all black holes in the universe are primordial (PBH) and suggested that an inverted picture of the galaxy formation is realized: supermassive black holes were formed prior to galaxy formation and subsequently seeded the latter. Possibilities of cosmological dark matter consisting of primordial black holes and of abundant cosmological antimatter are considered. A mechanism of 1993 anticipating all these phenomena and predicting an extended log-normal mass spectrum of PBH is described.
Sociodemographic, clinical profile, and psychiatric morbidities among patients with attempted suicide in a tertiary care center: A study from Central India

Background: Suicide is a major public health concern and is considered one of the leading causes of death globally. Previous suicidal attempts can be considered as a predictor of underlying psychiatric illness. Identifying factors behind suicidal attempt can help mental health professionals for early diagnosis and treatment as well as designing effective suicide prevention strategies. Aim: The aim of the study is to assess sociodemographic, clinical characteristics, and prevalence of psychiatric morbidities among patients with attempted suicide. Methods: A cross-sectional study was conducted in the emergency department of tertiary care hospital; patients of attempted suicide attending emergency from January 1, 2014, to January 1, 2020, constituted the sample for the study. Data were collected using semi-structured questionnaire which contained sociodemographic and clinical variables. All the subjects were administered mini-international neuropsychiatric interview (MINI), MINI Kid was applied for subjects <18 years, and MINI Plus was applied for subjects above 18 years. Patients were diagnosed according to the ICD-10 Classification of Mental and Behavioral Disorders for research. Results: Suicide attempt was seen more commonly in males, and the most common age group is between 21 and 40 years residing in urban settings. The most common method was consumption of unknown substances (75.35%). Factors leading to suicide are multidimensional in nature. 30.4% of the patients had impulsive traits. 86.5% of people who attempted suicide had a history of psychiatric illness. Detailed assessment of patients for psychiatric illness and psychosocial factors is crucial for planning suicide prevention strategies and policymaking. Conclusions: Young population is at high risk for suicide. More than 80% of these have diagnosable psychiatric illness.
Cooperatively enhanced reactivity and “stabilitaxis” of dissociating oligomeric proteins

Significance To gain insight into cellular metabolism, it is important to understand how proteins travel and self-organize within the cell. A characteristic feature of many important proteins is that they are oligomeric complexes, that is, they are composed of a few smaller subunits that can reversibly associate and dissociate. Here, we study the impact of dissociation on protein transport and self-organization. We find that dissociation can help proteins find and react with a target more rapidly, and that dissociating proteins spontaneously accumulate in regions in which they are most stable. Many functional units in biology, such as enzymes or molecular motors, are composed of several subunits that can reversibly assemble and disassemble. This includes oligomeric proteins composed of several smaller monomers, as well as protein complexes assembled from a few proteins. By studying the generic spatial transport properties of such proteins, we investigate here whether their ability to reversibly associate and dissociate may confer on them a functional advantage with respect to nondissociating proteins. In uniform environments with position-independent association–dissociation, we find that enhanced diffusion in the monomeric state coupled to reassociation into the functional oligomeric form leads to enhanced reactivity with localized targets. In nonuniform environments with position-dependent association–dissociation, caused by, for example, spatial gradients of an inhibiting chemical, we find that dissociating proteins generically tend to accumulate in regions where they are most stable, a process that we term “stabilitaxis. ”
Egyptian Journal of Health Care , 201 8 EJHC Vol . 9 No . 1 205 EJHC Assertiveness and Leadership Styles among Head Nurses

Background: Assertiveness is important for effective leadership and team building in nursing. Aim: to investigate the relationship between assertiveness and leadership styles among head nurses. Design: analytic cross-sectional. Setting: the study was carried out at Ain-Shams University Hospitals. Sample: It included all available (98) head nurses. Tools: A Selfadministered questionnaire which included two different tools, assertiveness scale and the Multifactor Leadership Questionnaire (MLQ) was used for data collection. Results: The results showed that 77.6% of head nurses‟ had a high level of assertiveness, and high percentages were having transformational and transactional leadership, while less than two-fifth were using passive/avoidant leadership style. Significant positive correlations were revealed between the scores of assertiveness and all domains of transformational leadership, and the contingent reward domain of the transactional style, and negative correlations with passive/ avoidant leadership. Significant positive correlations were shown between the scores of assertiveness and all types of leadership outcomes. Conclusion: The study concludes that head nurses in the study settings have a high level of assertiveness. They mostly use the transformational and transactional leadership styles. Meanwhile, the scores of the transformational leadership domains of idealized influence (attributed), idealized influence (behavior), and inspirational motivation have positive effects on their assertiveness, while the laisser-faire leadership has a negative impact on it. Recommendations: The study recommends training courses for head nurses in certain areas of assertiveness and in situational leadership.
Characteristics of auditory hallucinations in Indian patients with schizophrenia and bipolar affective disorder

Analysis of change in knowledge, attitude, and practices about COVID-19 following and awareness session in rural population of Western India

Background: Beginning of the pandemic showed our limitations in our understanding of the spread of the dreaded coronavirus-19 that had sprung from China and spread through thick and thin across the world. The measures to contain the spread of virus in the absence of specific treatment protocol had everyone grope for the solutions in a very short time frame. One such is the knowledge, attitude, and practice in the rural setup. Aim: The aim of the study is to measure the change in knowledge, attitude, and practices (KAP) regarding COVID-19 following an awareness session in rural population. Materials and Methods: A cross-section interventional study was carried out in January 2021. An interactive awareness session was conducted with the help of audiovisual aids following MOHFW guidelines for COVID-19, and the change in KAP about COVID-19 was measured by pre- and posttest standardized questionnaire. Results: Of all the participants, statistically significant change in knowledge was seen from 43% to 52%. The villagers were educated about preventive steps and a positive change was measured in the practice of changing masks regularly (84%–100%), maintaining social distancing (44%–64%), frequent handwashing (52%–64%). No change was seen in wearing of masks (92%) and negative change was seen in avoiding handshakes (32%–28%). The preventive practices regarding COVID-19 pandemic changed significantly from 50% to 58%. Our study measured positive attitude change toward getting vaccinated from 64% to 72%. Conclusion: A single, short awareness session led to significant change in KAP about COVID-19 in rural population.
Correlates of depression, anxiety, self-esteem, and suicidal ideas in COVID-associated mucormycosis patients and the effects of treatment

Aim: The aim was to study the correlates of depression, anxiety, self-esteem, and suicidal ideas in patients of COVID-associated mucormycosis (CAM) and effects of treatment. Materials and Methods: A cross-sectional, analytical study was performed in a tertiary care center in Western Maharashtra. By purposive sampling, 34 patients of CAM were included in the study with their informed consent and after obtaining ethical clearance. A self-made questionnaire to include demographic and clinical details was filled. Hospital Anxiety and Depression Scale (HADS), Rosenberg Self-Esteem Scale (RSES), and Suicidal Ideation Attributes Scale (SIDAS) were applied after initial diagnosis. The HADS, RSES, and SIDAS were reapplied after their operative treatment. Results: A significant reduction in anxiety and depression scores postoperatively was seen. No significant difference was found in self-esteem or suicidal ideas postoperatively in the study population. However, patients who underwent orbital exenteration showed a significant reduction in level of self-esteem with anxiety and depression postoperatively. No specific correlation was found between the computed tomography score, family history, intensive care unit admission, or orbital exenteration with anxiety, depression, self-esteem, and suicidal ideas. Conclusion: Levels of anxiety and depression in patients of CAM reduced significantly after treatment, but self-esteem worsened in males more than females owing to disfigurement. There is a need of psychological counseling in patients of mucormycosis undergoing a debilitating surgery both pre- and postoperatively for a better outcome and recovery.
ASSESSMENT OF A MOTHERS KNOWLEDGE OF PRIMARY SCHOOLS STUDENTS WITH ANEMIA IN AL- HILLAH CITY

Anemia is a pathological condition in which the number of red blood cells is low, the term anemia refers to the state in which the level of hemoglobin in the blood is lower than normal due to a deficiency in one or a group of essential nutrients, this disease is considered one of the common diseases in children in the primary school stage in many countries. This study aimed to assessment the knowledge of mothers who have children with anemia. The cross-sectional study design was conducted in primary health care centers in AlHilla city for the period March 2020 to May 2020. A total of 75 mothers had children with anemiahave been taken after obtaining written consent. The finding showed that the highest proportion 53.3 %of study sample in regarding the age of mothers with age group 28-37 years.The results also showed that the majority of women have poor knowledge of their children with anemia.There is a need to refreshing the role of parents, teachers’ association as a program for cooperation between teachers and mothers to control anemia.
Do Infants Really Learn Phonetic Categories?

Abstract Early changes in infants’ ability to perceive native and nonnative speech sound contrasts are typically attributed to their developing knowledge of phonetic categories. We critically examine this hypothesis and argue that there is little direct evidence of category knowledge in infancy. We then propose an alternative account in which infants’ perception changes because they are learning a perceptual space that is appropriate to represent speech, without yet carving up that space into phonetic categories. If correct, this new account has substantial implications for understanding early language development.
Optimism in Portuguese Adolescents: The Role of Anxiety and Positive Affect

The higher prevalence of anxiety and depression disorders in children and adolescents and the persistence of these disorders in adulthood show how important it is to investigate these concepts. Simultaneously, if we better understand the antecedents of, for example, anxiety, it will be more advantageous to define and implement some programs specifically for those ages. Like in adults, some investigations propose to study the effect of anxiety on optimism on samples of children or adolescents. In this study, we analyze the relations between anxiety, optimism, and affect in a sample of 155 students (mean age = 12 years). We took a particular interest in investigating the direction of influence between anxiety and optimism. The results showed a positive association between positive affect and anxious coping, and predictive power of these variables in explaining optimism, which seems to result from a contribution equivalent to that described on the two-factor structure of affectivity.

Learning Texture Generators for 3D Shape Collections from Internet Photo Sets

We present a method for decorating existing 3D shape collections by learning a texture generator from internet photo collections. We condition the StyleGAN [15] texture generation by injecting multiview silhouettes of a 3D shape with SPADE-IN [23]. To bridge the inherent domain gap between the multiview silhouettes from the shape collection and the distribution of silhouettes in the photo collection, we employ a mixture of silhouettes from both collections for training. Furthermore, we do not assume each exemplar in the photo collection is viewed from more than one vantage point, and leverage multiview discriminators to promote semantic view-consistency over the generated textures. We verify the efficacy of our design on three real-world 3D shape collections.
Tax Comprehension and Ethics Education Integration in Improving Tax Compliance Among Accounting Students: An Experimental Study

Tax education, especially at college level, has so far focused on academic aspects and tends to ignore ethical aspects. So far, ethics education has shown its role in increasing individual moral sensitivity. Given the importance of ethics education, an integration of ethics is needed in tax education, so that it is expected to help in shaping tax-compliant behavior among students. Based on these issues, this study aims to examine the combined effect of tax ethics education and tax comprehension on tax compliance. This research was conducted on 81 undergraduate accounting students with an experimental method. Based on the analysis using ANOVA, this study found that the integration of ethics in tax education can improve tax compliance, especially for students who have low tax comprehension. The results of this study indicate the importance of ethics integration in tax education, especially at the university level. Therefore, the results of this study are expected to be a consideration for universities to integrate ethical aspects of tax education, thus helping in the process of forming student moral awareness as taxpayers in the future.

E ﬃ cient Matching in the School Choice Problem ∗

Stable matchings in school choice needn’t be Pareto e ﬃ cient and can leave thou-sands of students worse o ﬀ than necessary. Call a matching  priority-neutral if no matching can make any student whose priority is violated by  better o ﬀ without violating the priority of some student who is made worse o ﬀ . Call a matching priority-e ﬃ cient if it is priority-neutral and Pareto e ﬃ cient. We show that there is a unique priority-e ﬃ cient matching and that it dominates every priority-neutral matching and every stable matching. Moreover, truth-telling is a maxmin optimal strategy for every student in the mechanism that selects the priority-e ﬃ
