Evaluation of the radiation damage parameters of ODS steel alloys in the first wall of deuterium‐tritium fusion‐fission (hybrid) reactors

One of the most important parameters in the design of the fusion‐fission hybrid reactor is the selection of the first wall material. Because the oxide dispersion‐strengthened (ODS) steel alloys have high temperature oxidation, high radiation resistance, good hardness, and corrosion resistance properties, they are thought first wall candidate materials for fusion and fission applications. The objective of this paper is to determine the best radiation damage parameters of various experimental and commercial ODS steels (namely, 12Y1, 12YWT, 1DS, IDK, Eurofer97, MA956, MA957, and PM 2000). Neutron spectrum and average neutron energy throughout blanket, displacement per atom, hydrogen and helium production, nuclear heating, and tritium breeding ratio were calculated by using Monte Carlo methods with Monte Carlo neutron‐photon transport code and nuclear libraries named as ENDF/B‐VI and CLAW‐IV. It is assumed that calculated reactor has been operated full power during a year and neutron wall load is 2.25 MW/m2 (1014 n/s). All investigated first wall materials should be replaced between 3.5 and 4 years. All investigated materials provide minimum required tritium breeding ratio value, and when considering all the calculations performed in this work, 1DS ODS steel is the most suitable first wall materials with respect to other investigated ODS steels.
Microalbuminuria as a predictor of cardiovascular morbidity in essential hypertensive patients: research study done at tertiary care centre in Western India

Background:Small amount of albumin excretion in urine, termed as microalbuminuria, has been postulated to be an indicator of endothelial dysfunction. This study was done to find the prevalence of microalbuminuria in patients with essential hypertension and to study the association of microalbuminuria with cardiovascular morbidity.Methods:This cross-sectional, observational study was conducted at the Department of Internal Medicine, Medical College and SSG Hospital, Baroda; by selecting 60 first time detected essential hypertensive patients, without any significant past or treatment history, attending Medicine outpatient department (OPD) or admitted in different wards at SSG hospital, for various reasons. A detailed history, clinical examination, basic blood investigation, urine albumin to creatinine ratio, electrocardiography (ECG) and 2D echo were done in all patients.Results:In this study, microalbuminuria was found in 24 (40%) cases with prevalence increasing with increasing age. A higher serum cholesterol, serum low density lipoprotein (LDL) and cholesterol/high density lipoprotein (HDL) ratio; left ventricular hypertrophy (LVH), ST-T changes and bundle branch block on ECG; LVH, hypokinesia and diastolic dysfunction on 2D echo; retinopathy on D fundus examination were all associated with higher microalbumin excretion in urine. Microalbuminuria was independent of age, sex, addiction to smoking, alcohol, BMI and severity/stage of hypertension. Thus, irrespective of existing known cardiovascular risk factors, microalbuminuria was associated with signs of cardiovascular morbidity.Conclusions:As a predictor of systemic vascular dysfunction, microalbuminuria can be used to stratify and prognosticate hypertensive patients at a higher risk of developing further vascular complications and they can be screened early for same.
Archaeal lipids reveal climate‐driven changes in microbial ecology at Lake El'gygytgyn (Far East Russia) during the Plio‐Pleistocene

Isoprenoid glycerol dialkyl glycerol tetraethers (iGDGTs) are commonly preserved molecular biomarkers of archaea whose distributions can be used to reconstruct past temperature, and possibly, methane and nitrogen cycling. To date, iGDGT systematics have not been widely investigated in Arctic lacustrine environments. Here, we analyze iGDGTs in sediments of Lake El'gygytgyn, located in the Russian Arctic, to reconstruct the paleoenvironmental conditions from the Pliocene to today using TEX86 and other indices. The TEX86‐inferred temperature history shows a long‐term warming trend, in stark contrast to other Arctic records and other proxies from Lake El'gygytgyn, suggesting that non‐temperature factors obfuscate the use of TEX86 at this site. Other GDGT‐based indices including the BIT Index, ΔRing Index, Methane Index and the GDGT‐0/crenarchaeol ratio suggest that TEX86 is strongly influenced by archaeal community changes. The most significant community shifts are observed c. 2.4 Ma and record an increase in Euryarchaeota production and/or a decrease in Thaumarchaeota production, which was driven by the establishment of permafrost and perennial lake ice during the early Pleistocene. Overall, this study demonstrates an important interpretative framework for iGDGTs in lacustrine systems and describes variations in Arctic climate and lake biogeochemistry over timescales of thousands to millions of years.
Concept of climate-charged airspaces: a potential policy instrument for internalizing aviation's climate impact of non-CO2 effects

ABSTRACT Approximately 50–75% of aviation's climate impact is caused by non-CO2 effects, like the production of ozone and the formation of contrail cirrus clouds, which can be effectively prevented by re-routing flights around highly climate-sensitive areas. Here, we discuss options how to incentivize re-routing approaches and apply multicriteria trajectory optimizations to demonstrate the feasibility of the concept of climate-charged airspaces (CCAs). We show that although climate-optimized re-routing results in slightly longer flight times, increased fuel consumption and higher operating costs, it is more climate-friendly compared to a cost-optimized routing. In accordance to other studies, we find that the averaged temperature response over 100 years (ATR ) of a single flight can be reduced by up to 40%. However, if mitigation efforts are associated with a direct increase in costs, there is a need for climate policies. To address the lack of incentivizing airlines to internalize their climate costs, this study focuses on the CCA concept, which imposes a climate charge on airlines when operating in highly climate-sensitive areas. If CCAs are (partly) bypassed, both climate impact and operating costs of a flight can be reduced: a more climate-friendly routing becomes economically attractive. For an exemplary North-Atlantic network, CCAs create a financial incentive for climate mitigation, achieving on average more than 90% of the climate impact reduction potential of climate-optimized trajectories (theoretical maximum, benchmark). Key policy insights Existing climate policies for aviation do not address non- effects, which are very sensitive to the location and the timing of the emission. By imposing a temporary climate charge for airlines that operate in highly climate-sensitive regions, the trade-off between economic viability and environmental compatibility could be resolved: Climate impact mitigation of non- effects coincides with cutting costs. To ensure easy planning and verification, climate charges are calculated analogously to en-route and terminal charges. For climate mitigation it is therefore neither necessary to monitor emissions ( , etc.) nor to integrate complex non- effects into flight planning procedures of airlines. Its implementation is feasible and effective.
Enhanced influence of ENSO on winter precipitation over southern China in recent decades

Using observation, reanalysis and model datasets, the impact of the El Niño-Southern Oscillation (ENSO) on winter precipitation in southern China is re-examined. The results show that positive correlation between ENSO and winter precipitation in southern China after 1995 is significantly higher than that before 1995. Significant positive correlation is located mainly over the southern coastal areas of China before 1995, whereas the positive correlation extends northward to the Yangtze River basin after 1995. These changes in the relationship between ENSO and winter precipitation are related to the ENSO pattern and Philippine anticyclone changes. An increasing trend is observed in the ENSO amplitude, while the area with cooler SST in the Philippine seas extends westward after 1995 compared with that before 1995, leading to an extension of the anticyclone from the east side to the west side of the Philippines. The westward extension of anticyclone after 1995 could enhance the winter precipitation over southern China through modifying water vapour fluxes and vertical motion. Model results support the observation analyses of the changes in ENSO-precipitation relationship and the corresponding mechanism. The mean SST changes could also modify the ENSO-precipitation relationship.
‘Chatting Shit’ in the Jobcentre: Navigating Workfare Policy at the Street-Level

Since the mid-1980s, out-of-work benefit receipt in the UK has been increasingly governed by a ‘workfarist’ mesh of conditionality and activation policies. A wealth of research has found that conditionality and activation policies trigger a range of harmful outcomes for benefit claimants. However, this research largely ignores how claimants may struggle against these policies to eschew harmful outcomes. Drawing on longitudinal interviews with 15 young men, this article demonstrates how claimants can subvert policy implementation to prioritise their own needs and interests. It is concluded that claimant struggles against policy implementation most accurately reflect survival strategies and are predominantly rooted in the ‘material nexus’ of class-based inequalities in capitalist societies.
Regioselective synthesis of 6’’-O-lauroyl-1-kestose and 6’’’-O-lauroylnystose by sequential enzymatic reactions of transfructosylation and acylation

Abstract Fructan fatty acid esters are amphiphilic compounds with potential applications in the food industry due to their surface-active properties on the air/water interface. In this work, the regioselective synthesis of fatty acid esters of short-chain inulin-type fructooligosaccharides (FOS) was carried out in a two-step process comprising sequential enzymatic reactions of transfructosylation and acylation. In the first step, Schedonorus arundinaceus sucrose:sucrose 1-fructosyltransferase (1-SST, EC 2.4.1.99) converted sucrose (600 g/L) into the trisaccharide 1-kestose and the tetrasaccharide nystose in a ratio 9:1 with their sum accounting for 53% (w/w) of total carbohydrates. In the second step, the FOS mixture was transesterified with vinyl laurate in 2-methyl-2-butanol by immobilized Candida antarctica lipase B (CALB) (EC.3.1.1.3). NMR analysis of the synthesized monolaurate FOS esters revealed a regioselective acylation of the 6-OH of the terminal fructosyl moiety of both 1-kestose and nystose. The hydrophilic-lipophilic balance (HLB) values of 6’’-O-lauroyl-1-kestose and 6’’’-O-lauroylnystose were 14.7 and 15.7, respectively; which suggests their use as oil in water (O/W) emulsifiers. The main compound 6’’-O-lauroyl-1-kestose with critical micelle concentration (CMC) of 0.6 mM and surface tension of 45.8 mN/m proved to be a more efficient surfactant than 6’’’-O-lauroylnystose (CMC 5.38 mM) and surface tension 36.26 mN/m). We report a regioselective method for the synthesis of lauryl-FOS using the abundant and renewable resource sucrose as the starting substrate.
No Tendencies of Personality Traits in Blood Groups: a cross-sectional study conducted on Bangladeshi people.

No studies to date came up with fruitful consequences regarding if or not there is a relationship between blood groups and personality traits rather providing most conflicting, floundering, discrete, equivocal outcomes. Traditionally, Japanese and Korean people support the conception that there are natural inclinations of personality traits in blood groups. Our study aims to explore the rationality of this conception that personality traits and blood groups are interrelated. However, responses of the participants were collected using 50 items big-five factor personality inventory developed by Goldberg: Extraversion, Agreeableness, Neuroticism, Conscientiousness, Intellect (Openness to experience). A two way multivariate analysis (MANOVA) was performed on total 148 participants including 85 males and 65 females using IBM SPSS Statistics version 26. MANOVA results revealed that neither the significant main effect of blood groups [F (15,414) = 1.102, p > 0.05] nor had the significant interaction effect of blood groups and gender [F (15,414) = 1.111, p > 0.05] on the combined dependent variables. But this study found significant main effect of gender on the combined dependent variables [F (5,136) = 4.520, p = 0.001, (1-β) = 0.967, η2 = 0.143]. This present study does not support the idea that there is significant relationship between blood groups and personality traits. But the idea that male personality significantly differs from female personality is well-supported by this study.
Performance Evaluation of Electrically Driven Agricultural Implements Powered by an External Generator

In the last decade, many studies have been conducted on tractor and agricultural machinery electrification. In particular, the electrification of power take-off (PTO)-powered implements could support many benefits, such as improved comfort and safety during implement connection, less noisiness, accurate control of the implement rotational speed, and fuel consumption reduction. However, commercially available tractors do not generate sufficient electric power to run electrified implements. A solution to this issue is powering eventual electrified implements with an external electric generator powered by the PTO and mounted with the front three-point linkage. This study aimed to evaluate the potential benefits of using this combination with respect to PTO powered implements. The types of implements analyzed in detail in this study were a sprayer and a mulcher. Field tests were performed acquiring performance, operational, and environmental parameters. Results show that on the electrified implements, the absence of the cardan shaft and hydraulic remotes shortened the time required for the hitching phase and reduced the in-work noisiness. Field tests demonstrated that the electrified implements permitted an improvement of the fuel consumption per hectare, up to 33.3% and 29.8% lower than their PTO-powered homologue for the sprayer and the mulcher, respectively.
Behavioral Pattern Analysis between Bilingual and Monolingual Listeners’ Natural Speech Perception on Foreign-Accented English Language Using Different Machine Learning Approaches

Speech perception in an adverse background/noisy environment is a complex and challenging human process, which is made even more complicated in foreign-accented language for bilingual and monolingual individuals. Listeners who have difficulties in hearing are affected most by such a situation. Despite considerable efforts, the increase in speech intelligibility in noise remains elusive. Considering this opportunity, this study investigates Bengali–English bilinguals and native American English monolinguals’ behavioral patterns on foreign-accented English language considering bubble noise, gaussian or white noise, and quiet sound level. Twelve regular hearing participants (Six Bengali–English bilinguals and Six Native American English monolinguals) joined in this study. Statistical computation shows that speech with different noise has a significant effect (p = 0.009) on listening for both bilingual and monolingual under different sound levels (e.g., 55 dB, 65 dB, and 75 dB). Here, six different machine learning approaches (Logistic Regression (LR), Linear Discriminant Analysis (LDA), K-nearest neighbors (KNN), Naïve Bayes (NB), Classification and regression trees (CART), and Support vector machine (SVM)) are tested and evaluated to differentiate between bilingual and monolingual individuals from their behavioral patterns in both noisy and quiet environments. Results show that most optimal performances were observed using LDA by successfully differentiating between bilingual and monolingual 60% of the time. A deep neural network-based model is proposed to improve this measure further and achieved an accuracy of nearly 100% in successfully differentiating between bilingual and monolingual individuals.
The Multiple Causes of Obesity

Obesity is known to cause physical and metabolic diseases. It is often assumed by people (including the healthcare workers) that the person with obesity lacks self-control in matters of diet and physical exercise, and is therefore responsible for his or her weight. Persons with obesity have to face sarcasm, barbs, and discrimination due to their condition. They often have difficulty in getting jobs or have to accept lower than standard pay for their work. Although weight gain requires calorie intake in excess of calorie expenditure, it is sometimes not easy for the person to restrict calories due to the underlying causes of obesity. The body resists losing weight, and attempts to hoard calories by reducing the metabolic rate. In this chapter we have explained and classified the causes of obesity into endogenous and exogenous. The endogenous causes include genetic and epigenetic causes, maternal factors, and hormonal causes, while exogenous causes include obesogenic environment, lifestyle, and weight-gain promoting medicines. It must be realized that losing weight and keeping it off is not easy for a person with obesity.
Second Life: A Virtual Environment to Reduce Students’ Foreign Language Anxiety

Second language acquisition (SLA) is a complex construct in which not only cognitive factors play a crucial role, but also affective ones. In the last decades, the analysis of affective factors in second (L2) and foreign language (FL) learning has gained prominence. Research has shown a strong correlation between language learning and aspects such as personality, motivation, attitude, or anxiety, to name but a few (e.g., Gardner, 2020; Hewitt & Stephenson, 2011; MacIntyre & Gardner, 1989). The purpose of this paper is to examine whether Foreign Language Anxiety (FLA) levels could be lessened using Virtual Worlds (VWs) such as Second Life (SL) for language teaching. This investigation compares the FLA levels of an Experimental Group (EG), which completed three activities through SL, with a Control Group (CG), which completed the same activities in the traditional classroom. Results indicate that the FLA levels of participants in the EG decreased as lessons went by in comparison with those participants in the CG. Moreover, findings suggest that the confidence of those participants working in SL increased as time went by. This boost in learners’ confidence could be attributed to the crucial role played by anonymity in VWs.
Isolating Large‐Scale Smoke Impacts on Cloud and Precipitation Processes Over the Amazon With Convection Permitting Resolution

Absorbing aerosol from biomass burning impacts the hydrological cycle and radiation fluxes both directly and indirectly via modifications to convective processes and cloud development. Using the ICOsahedral Non‐hydrostatic modelling framework in a regional configuration with 1,500 m convection‐permitting resolution, we isolate the response of the Amazonian atmosphere to biomass burning smoke via enhanced cloud droplet number concentrations Nd (aerosol‐cloud interactions; ACI) and changes to radiative fluxes (aerosol‐radiation interactions; ARI) over a period of 8 days. We decompose ARI into contributions from reduced shortwave radiation and localized heating of the smoke. We show ARI influences the formation and development of convective cells: surface cooling below the smoke drives suppression of convection that increases with smoke optical depth, while the elevated heating promotes initial suppression and subsequent intensification of convection overnight; a corresponding diurnal response (repeating temporal response day‐after‐day) from high precipitation rates is shown. Enhanced Nd (ACI) perturbs the bulk cloud properties and suppresses low‐to‐moderate precipitation rates. Both ACI and ARI result in enhanced high‐altitude ice clouds that have a strong positive longwave radiative effect. Changes to low‐cloud coverage (ARI) and albedo (ACI) drive an overall negative shortwave radiative effect, that slowly increases in magnitude due to a moistening of the boundary layer. The overall net radiative effect is dominated by the enhanced high‐altitude clouds, and is sensitive to the plume longevity. The considerable diurnal responses that we simulate cannot be observed by polar orbiting satellites widely used in previous work, highlighting the potential of geostationary satellites to observe large‐scale impacts of aerosols on clouds.
Service innovative work behavior in the hotel firms: The role of servant leadership and harmonious passion

ABSTRACT The current paper proposes to study the role of servant leadership in enhancing harmonious passion among employees, and further to ascertain if harmonious passion acts as a mediating mechanism linking servant leadership and service innovative work behavior (IWB). This study also recognizes the importance of creative self-efficacy as the boundary condition between harmonious passion and service IWB. Data were collected from employees working in four- and five-star hotels of Pakistan with a sample of 220 participants. Research findings provided justification for the mediating effect of harmonious passion for servant leadership-service IWB linkage. Furthermore, the relationship between harmonious passion and service IWB was strengthened to the extent that harmoniously passionate employees showed higher creative self-efficacy. Practitioners looking to enhance harmonious passion and service IWB can do so by developing the servant leadership qualities of managers. This paper carries value as the literature pertaining to harmonious passion is still small but increasing and enriches knowledge in understanding the role of servant leadership as reaping the service IWB benefits of harmonious passion among employees in the hospitality industry.
Frequency and type of adverse drug reactions related to multidrug-resistant tuberculosis therapy

Background: Adverse drug reactions (ADRs) are inevitable consequences of multidrug-resistant tuberculosis drug therapy. Reporting of ADR in India is poor and inadequate. ADRs monitoring forms an integral part of pharmacovigilance. ADRs with second line anti-tuberculous therapy (ATT) have been mentioned as obstacles in the management of multidrug-resistant tuberculosis (MDR-TB). Objectives of the study was to study the frequency and type of adverse drug reaction related to MDR-TB therapy.Methods: 72 patients diagnosed as MDR-TB and enrolled for DOTS-PLUS (CAT.IV) regimen at NTEP centre, KIMS HUBLI were included. This was a prospective observational study. All patients were followed up for a period of 9 months from the day of commencement of treatment. Adverse drug reactions were determined by monthly clinical and biochemical monitoring of patients to identify ADRs.Results: Among 72 Patients, 42 (58.3%) were males. 44 out of 72 patients experienced at least one type of ADRs (61.1%). Mean age was 35.86±12.62 and mean weight was 42.00±9.05. Four most common ADRs reported were Gastro-intestinal symptoms (29.2%), anorexia (15.3%), giddiness (12.5%), and pain at injection site (11.1%). Highest percentage of ADRs were seen in patients of age group>60 years (66.7%). ADRs were most commonly reported in first 3 months of initiation of therapy. 9 out of 72 patients (12.5%) or 20.5% of 44 patients who showed ADRs required change of treatment. There was a significant impact of ADRs on treatment among those with ADRs (p=0.01). Conclusion: ADRs of varying severity are common in patients of MDR-TB on DOTS-PLUS regimen, occurring in more than half of the cases, with around one fifth requiring change of MDR-TB treatment.
