Creating value in and for everyday life: Ambulatory assessment in physical activity and sedentary behavior research
Authors: Reichert Markus , Nigg Carina 
Published: February 2023

Physical activity and sedentary behavior play a crucial role for both physical and mental health. While epidemiological studies provide crucial evidence for the long-term health effects of physical activity and sedentary behavior, it is less well-known how physical activity and sedentary behavior are related to mental health in everyday life. Ambulatory assessment is a promising approach, referring to various assessment methods that allow studying dynamic behavioral and psychological processes in people’s everyday life (Trull & Ebner-Priemer, 2013). In this symposium, we present research using state-of-the art ambulatory assessment methodology to investigate associations between physical activity, sedentary behavior, and mental health constructs in everyday life. The first two presentation address how associations between physical activity or sedentary behavior and mood are moderated by environmental and social factors in everayday life. The third presentation elaborates on a novel methodological approach using time-series analysis of step count data to identify the resilience process. The three presentations should invite discussions on how ambulatory assessment can be used in sports science to advance our understanding between physical activity, sedentary behavior, and mental health in and for everyday life.

Bioremediation based on microbial technologies has been extensively used for treating coloured textile wastewater. In this research, the potential application of the indigenous and exogenous bacterial cultures, found as biofilm were investigated for colour removal. Initial study in the treatment of the textile wastewater showed that the mechanism involved in decolourisation was degradation, which was carried out via molecular technique involving amplification of the DNA sequence responsible for decolourisation using pure dye; Orange. In laboratory scale experiment, the bacteria were grown as mixed culture in suspension and biofilm using shake flasks technique. Their abilities to decolourise textile wastewater were studied under semianaerobic conditions. Generally, bacteria in the form of biofilms were found to remove colour at faster rates compared to that of suspended cells. Evidence of biofilm formation during decolourisation of textile wastewater was also examined using SEM.
An appraisal of a waste water treament plant for pulp and paper mill
Authors: Deshpande V. P. 
Published: February 2023

Due to stringent requirement so fregional regulatory agencies as also about environmental protection, there is a growing concern that is being shown in implementing wastewater management schemes. However, the approach towards solving wastewater management problem is still not that serious as a result, wastewater treatment plants are inadequately designed and constructed. Moreover, after commissioning of treatment plant, there are problems of poor operation and maintenance. All these finally adversely affect the treated wastewater quality, thus, defeating the basic objective of environmental protection. A filed study conducted on one of the pulp and paper manufacturing industry has been presented in the paper alongwith shortcomings and possible remedial measures for achieving improvements.

Abstract
We present a comparison of theoretical predictions of dust continuum and polycyclic aromatic hydrocarbon (PAH) emission with new JWST observations in three nearby galaxies: NGC 628, NGC 1365, and NGC 7496. Our analysis focuses on a total of 1063 compact stellar clusters and 2654 stellar associations previously characterized by the Hubble Space Telescope in the three galaxies. We find that the distributions and trends in the observed PAH-focused infrared colors generally agree with theoretical expectations, and that the bulk of the observations is more aligned with models of larger, ionized PAHs. These JWST data usher in a new era of probing interstellar dust and studying how the intense radiation fields near stellar clusters and associations play a role in shaping the physical properties of PAHs.
Density Profiles of Collapsed Rotating Massive Stars Favor Long Gamma-Ray Bursts

Published: February 2023

Abstract
Long-duration gamma-ray bursts (lGRBs) originate in relativistic collimated outflows—jets—that drill their way out of collapsing massive stars. Accurately modeling this process requires realistic stellar profiles for the jets to propagate through and break out of. Most previous studies have used simple power laws or pre-collapse models for massive stars. However, the relevant stellar profile for lGRB models is in fact that of a star after its core has collapsed to form a compact object. To self-consistently compute such a stellar profile, we use the open-source code GR1D to simulate the core-collapse process for a suite of low-metallicity rotating massive stellar progenitors that have undergone chemically homogeneous evolution. Our models span a range of zero-age main-sequence (ZAMS) masses: M
ZAMS = 13, 18, 21, 25, 35, 40, and 45M
☉. All of these models, at the onset of core-collapse, feature steep density profiles, ρ ∝ r
−α
, with α ≈ 2.5, which would result in jets that are inconsistent with lGRB observables. We follow the collapses of four of the seven models until they form black holes (BHs) and the other three models until they form proto-neutron stars (PNSs). We find, across all models, that the density profile outside the newly formed BH or PNS is well represented by a flatter power law with α ≈ 1.35–1.55. Such flat density profiles are conducive to the successful formation and breakout of BH-powered jets and are, in fact, required to reproduce observable properties of lGRBs. Future models of lGRBs should be initialized with shallower post-collapse stellar profiles, like those presented here, instead of the much steeper pre-collapse profiles that are typically used.
Genetic evidence for parthenogenesis in the small carpenter bee Ceratina dallatoreana (Apidae, Ceratinini) in its native distribution range
Authors: Mikát Michael , Straka Jakub 
Published: February 2023

Arrhenotoky is the typical mode of reproduction in Hymenoptera. Diploid females develop from fertilized eggs, whereas haploid males originate from unfertilized eggs. However, some taxa of Hymenoptera have evolved thelytoky, in which diploid females originate parthenogenetically from unfertilized diploid eggs. In contrast to some other hymenopteran lineages, like ants and parasitic wasps, thelytoky is generally very rare in bees.
Here, we evaluated the frequency of thelytoky in the small carpenter bee Ceratina dallatoreana, which was previously assumed to be thelytokous. By comparing genotypes of microsatellite loci between mothers and their offspring, we found that all female offspring were genetically identical to their mothers. We conclude that parthenogenesis is the prevailing and perhaps obligate mode of reproduction in C. dallatoreana. We also classify the cytological mode of this parthenogenesis as apomixis, or automictic parthenogenesis with central fusion and extremely reduced or non-existing recombination, because offspring showed no decrease of heterozygosity.
Because sociality is influenced by relatedness and Ceratina are ancestrally facultatively social, the high relatedness afforded by parthenogenesis should associate with social living in the nest. In accordance with previous work, however, we found no social nests of C. dallatoreana.
Comment les entreprises françaises ajustent-elles leur niveau d’emploi ?
Authors: Duhautois Richard , Petit Héloïse 
Published: February 2023

Dans la lignée des travaux de Davis et Haltiwanger [1999], nous étudions les pratiques d’ajustement de l’emploi des établissements français. Nous estimons les relations entre flux d’emploi (création et destruction) et de salariés (entrées et sorties) à l’appui des EMMO-DMMO (une base de données des mouvements sur le marché du travail couvrant les établissements privés de 10 salariés ou plus) pour la période 1999-2010. Nos estimations montrent la contribution importante des entrées et sorties en contrats à durée indéterminée (CDI) aux ajustements de l’emploi. En période de croissance des effectifs, les entrées en contrats à durée déterminée (CDD), comme celles en CDI, ont un poids important. Mais en période de diminution des effectifs, les deux types de flux s’ajustent différemment : les entrées en CDD ralentissent mais ce sont surtout les fins de CDI qui s’intensifient.

Comment faire des typologies en politique comparée ?
Authors: Chevalier Tom 
Published: February 2023

Typologies, taxinomies, classifications : de nombreuses confusions règnent autour de ces notions mobilisées dans les travaux procédant à des comparaisons en politique comparée et s’appuyant sur l’élaboration de « types ». Cet article vise à en clarifier les usages en identifiant quatre formes de typologie, à distinguer selon le mode d’élaboration des types (induction vs déduction) et leur opérationnalisation (centrée sur la constitution de groupes vs centrée sur l’analyse de cas) : la typologie « classificatrice », la typologie « taxinomique », la typologie « explicatrice », et la typologie « idéale-typique ». Il est également souligné leurs apports et limites, l’importance de l’état de l’art dans le choix de telle ou telle typologie, ainsi que les différents statuts heuristiques des types élaborés dans chacune d’entre elles.
Relationship between Different Types of Intelligence and Effect of Music on Intelligence
Authors: Singh Mohita , Sachdev Sunil , Singh Amrita , Raj Dev 
Published: February 2023

Background and Aims:
Intelligence is an abstract ability which is easily identifiable and recognizable but interestingly very hard to define. The study of intelligence is a dynamic field which is continuously evolving and expanding. The idea of multiple intelligence includes both interpersonal (to understand other individuals' emotions and intensions) and intrapersonal (to understand one's own emotions) intelligence. The present study was performed to assess the intelligence quotient (IQ), emotional quotient (EQ), social intelligence (SI), and resilience level of subjects and to assess the effect of music on different types of intelligence.

Materials and Methods:
The present study was conducted on 100 college-going students chosen randomly. The study was carried out in two phases. In the first phase, baseline parameters of IQ, EQ, SI, and resilience level were assessed. They were asked to listen to receptive music for 1 month and to maintain the record of the same. In the second phase, the effect of music was studied on parameters.

Results:
Significant correlation was found between IQ, EQ, SI, and resilience scores. Correlation and paired t-test values of each parameter analyzed between baseline and post music intervention levels exhibited significant difference. Comparison of mean values of parameters in males and females studied at baseline level and post music intervention level also exhibited statistical differences at different levels of significance.

Conclusion:
Music improves cognitive abilities in both males and females with more effect on IQ in males and SI in females.
Teenage Pregnancy and its Outcomes in a Tertiary Care Hospital in Assam
Authors: Borah Madhur , Das Bishnu Ram 
Published: February 2023

Background:
Teenage pregnancy is one of the determinants of high maternal morbidity and mortality. Assam is known for its highest contribution of maternal death in India. In Assam, around 31% of teenage girls get married before the age of 18, and around 12% teenage girls become mothers before they turn out to be 18 years.

Objectives:
The objective of this study is to know the maternal and fetal outcomes of teenage pregnancy and its determinants in a tertiary care setting in Assam.

Materials and Methods:
A cross-sectional study was conducted among 118 teenage mothers admitted to Jorhat Medical College and Hospital from June to August 2019. Required data on sociodemographic characteristics of the mother, antenatal, intranatal, and postnatal histories, and maternal and fetal outcomes of the pregnancy, were collected in predesigned and pretested schedule. Data analysis was done using Microsoft Excel software. Ethical approval was obtained from the Institutional Ethics Committee.

Results:
Among the 118 teenage mothers which constitute 14.6% of total deliveries conducted during the study period, 61% were anemic during pregnancy and 75.42% of teenagers had term delivery while 19.49% had either preterm or postterm deliveries. Cesarean section was done for 50.85% of pregnancies and 45.77% of teenage mothers had complications such as eclampsia, prolonged labor, cephalopelvic disproportion, and premature rupture of membrane during labor. About 42.73% of the newborns were found to be low birth weight babies. A statistically significant association was found between determinants such as lower socioeconomic class, younger age at marriage, less education of mothers, lack of knowledge about contraceptives, and teenage pregnancy.

Conclusion:
Our study findings indicated a high percentage of teenage pregnancy and increased complications among teenage mothers and newborns.
Prevalence of preoperative anxiety in patients posted for surgical procedures and its relation to the doses of anesthetic drugs: A cross-sectional study
Authors: Omkaram Sindhuja , Reddy C. Gowtham , Murthy P. S. , Chaudhury Suprakash 
Published: February 2023

ABSTRACT

Background:
In patients undergoing surgical procedures, preoperative period is one of the most worrying periods. There are only few studies which revealed that increased preoperative anxiety is associated with increased requirements of doses of anesthetic agents.

Aim:
The aim of this study is to assess the prevalence of preoperative anxiety in patients posted for surgical procedures and its relation to the doses of anesthetic drugs.

Materials and Methods:
This is a cross-sectional, analytical study done between January 2021 and April 2021. A total of 100 patients undergoing surgery have given consent to participate in the study by filling self-designed questionnaire, Amsterdam Preoperative Anxiety and Information Scale (APAIS). Data analysis was done by SPSS version 24 using appropriate statistical tests.

Results:
Preoperative anxiety was noted in 21% of the patients who were undergoing surgery. The association between preoperative anxiety and need for increase in the doses of anesthetic agents during intraoperative period was found to be statistically significant (P < 0.004).

Conclusion:
A significant number of patients required increased amounts of anesthetic drugs to reduce anxiety during intraoperative period. Therefore, appropriate methods have to be introduced to address the concerns of patients undergoing surgery and thereby reducing anxiety.
Positive mental health for all serving the under-served

Published: February 2023

ABSTRACT
Mental disorders are major contributors to global burden of disease measured in Disability Adjusted Life Years (7% of all disease burden in 2017). Large treatment gaps for these disorders exist in all parts of the world. In India, overall treatment gap for mental disorders was found to be 83%. Women, children and adolescents, ethnic minorities, LGBTQ+ community, elderly and those living in remote and inaccessible areas have disproportionately higher rates of mental illness. They face unique and characteristic barriers to access to mental healthcare which increases treatment gap. These gaps have persisted despite global efforts and interventions to mitigate these barriers. Hence, there is a need to find alternatives to reduce mental health gap in these groups. Positive Mental Health interventions focuson well-being and health promoting activities, rather than on illness. The potential role of these interventions in promoting mental health and reducing treatment gap has been explored in this article.
Assessment of Perception of Crew on Habitability Factors Onboard Naval Afloat Units Assessment of Perception of Crew Regarding Habitability Factors Onboard Naval Afloat Units
Authors: Sharma Anmol , Batlish Rajesh , Ali Khan Muzzafar 
Published: February 2023

Background and Objectives:
Habitability onboard a warship is multifactorial and constitutes the environment in which the crew operates and accommodates while at sea or at harbor. Maritime work environment is a complex man-machine interaction, with human being the dynamic component as the machine is mostly run by set protocols and algorithms. Efficiency of the dynamic aspect of the man machine interaction is driven by multiple correlated and interrelated factors which can be linked to the ambient and external environment in nature. This study was therefore conducted to survey upon the crew serving onboard Indian Naval Ships as to assess crew perception toward various habitability factors onboard.

Materials and Methods:
The descriptive study was carried on board various naval warships. A questionnaire-based analysis was conducted on 384 personnel on active duty.

Results:
Majority of participants agreed that habitability factors have a direct impact on their efficiency while working. Food, ventilation, and adequate living spaces are most crucial with the maximum positive impact on the crew as determined by the survey.

Interpretation and Conclusion:
Subsequent increase in the quality and variety of equipment with an ergonomical approach is the way forward for an efficient and happy crew. A happy and satisfied seafarer on board a ship is the pivot point to determine the efforts in place and the mission in hand.
Correlation of Erythroferrone and Hepcidin Hormones with Iron Status Levels in Patients with Iron Deficiency
Authors: Talawy Tiba Sabah , Bylappa Sunil Kumar , Ismail Marwan , Kandakurti Praveen Kumar , Gopakumar Aji , Babker Asaad Ma 
Published: February 2023

INTRODUCTION:
Iron-deficiency anemia (IDA) can be grouped under low hepcidin and high erythroferrone (ERFE) anemia. There is a negative correlation between ERFE and hepcidin, irrespective of the type of anemia. ERFE is a mediator of the response to erythropoietic stress, suppressing hepcidin to promote the mobilization of stored iron and the absorption of dietary iron.

OBJECTIVE:
The objective was to determine the effect of ERFE hormone on hepcidin level as iron metabolism regulator in patients with iron deficiency (ID).

METHODS:
The study included 50 female patients with ID who were investigated for complete blood count, serum levels of ferritin, and serum levels of iron using automated hematology, immunology, and chemistry analyzer. ERFE and hepcidin were measured by a specific enzyme-linked immunosorbent assay kit.

RESULTS:
The serum ERFE levels were higher than normal in all cases and were negatively correlated with serum hepcidin (r = −0.023). In IDA, serum ERFE concentration had a nonsignificant negative correlation with hemoglobin (Hb) concentration. Serum hepcidin concentration had a nonsignificant negative correlation with Hb concentration. Serum ERFE had a nonsignificant negative correlation with Hb% in severe IDA (r = −0.679; P = 0.094) and mild IDA (r = −0.068; P = 0.789). ERFE had a nonsignificant positive correlation with Hb% in moderate IDA (r = 0.069; P = 0.793). Serum hepcidin had a nonsignificant positive correlation with Hb% in severe IDA (r = 0.036; P = 0.939). Serum hepcidin had a nonsignificant negative correlation with Hb% in mild IDA (r = −0.079; P = 0.764) and moderate IDA (r = −0.179; P = 0.491).

CONCLUSIONS:
The potential of ERFE and hepcidin in diagnosing and categorizing ID disorders is promising. Understanding the mechanism of ERFE/hepcidin interaction will help in developing ERFE-/hepcidin-targeted therapies.
