Insect faunal succession on buried goat carcass in Aligarh Region of Uttar Pradesh, India, with implications in forensic entomology
Authors: Sharif Swaima , Qamar Ayesha 
Published: September 2021

Abstract
Background
Studies on the insect fauna of animal corpses, used as a vertebrate model, may help forensic investigation cases to estimate the post-mortem-interval (PMI), cause of death, and crime-scene location. Likewise, entomofauna of buried corpses can assist in determining the post-burial-interval (PBI), movement of the body or hiding of the crime. The bodies buried under the soil decompose at a slower rate than the body exposed. Also, there are fewer insects that can go underground to locate the corpse. Such types of studies on the insect fauna of buried carrion can help in forensic investigation cases. The current study aims to determine the succession of a goat carcass buried shallowly in an outdoor habitat of the Aligarh Region, North India.

Results
In the present study, we examined a goat carcass buried at a depth of nine inches to determine the type of insects capable of colonizing buried animal carcass in the study area of Aligarh, Uttar Pradesh, India. We have found five species of Diptera, three species of Coleoptera, one Hemipteran species, and one Hymenopteran species. Adult Dipterans found during different samplings were Megaselia scalaris (Loew 1866), Chrysomya megacephala (Fabricius 1794), and Calliphora vicina (Robineau-Desvoidy, 1830). Dipterans’ immature stages were found to be of Synthesiomyia nudiseta (van der Wulp, 1883) and Hydrotaea capensis (Wiedemann, 1830) Megaselia scalaris. Adults of Saprinus quadriguttatus (Fabricius, 1798), Saprinus splendens (Paykull, 1811), and Onthophagous quadridentatus (Fabricius, 1798) of order Coleoptera. Adult Cydnus species (Fabricius, 1803) of Hemiptera and Dorylus species (Fabricius, 1793) of Hymenoptera have also been recorded. During the sampling, the authors reported the stages of carcass disintegration and the insects associated with it.

Conclusions
Flies, beetles, and ants have been recorded in association with the buried goat carcass, which may add to the knowledge of colonization of buried bodies in India and around the globe. S. nudiseta, H. capensis, and M. scalaris, which are found on the goat carrion in the current study, have also been reported on human corpses in the past. Furthermore, M. scalaris found consistently on two sampling dates beneath the ground on the goat carcass and was also seen running on the grave’s surface. In addition, authors have reported several species belonging to different order and families, corresponding to various stages of decomposition of corpse which were earlier not known from buried corpses from India. So, it is crucial and may have implications in medicolegal cases.

Abstract
Background
Chronic musculoskeletal pain (CMP) may lead to reduced physical function and is the most common cause of chronic non-cancer pain. Currently, the pharmacotherapeutic options against CMP are limited and frequently consist of pain management with non-steroidal anti-inflammatories, gabapentinoids, or opioids, which carry major adverse effects. Although the effectiveness of medical cannabis (MC) for CMP still lacks solid evidence, several patients suffering from it are exploring this therapeutic option with their physicians.

Objectives
Little is known about patients’ perceptions of their MC treatment for CMP. We aimed to increase this knowledge, useful for healthcare professionals and patients considering this treatment, by conducting a scoping literature review, following guidance by Arksey and O’Malley, to describe the views and perceptions of adult patients who had consumed MC to relieve chronic CMP.

Methods
Databases (PUBMED, EMBASE, Web of Science) and websites were searched using combinations of controlled and free vocabulary. All studies and study designs reporting on patients’ perceptions regarding MC against CMP were considered. Studies had to include adult patients reporting qualitatively or quantitatively, i.e., through questionnaires, on MC use to treat CMP or other non-cancer pain, since studies reporting exclusively on perceptions regarding CMP were very rare. Study characteristics were extracted and limitations of the study quality were assessed. The review includes patients’ demographic characteristics, patterns of MC use, perceived positive and negative effects, use of alcohol or other drugs, reported barriers to CM use, and funding sources of the studies.

Results
Participants of the 49 included studies reported that MC use helped them to reduce CMP and other chronic non-cancer pain, with only minor adverse effects, and some reported improved psychological well-being.
In the included studies, men represent between 18 and 88% of the subjects. The mean age of participants in these studies (42/49) varied between 28.4 and 62.8 years old. The most common route of administration is inhalation.

Conclusion
MC users suffering from CMP or other chronic non-cancer pain perceived more benefits than harms. However, the information from these studies has several methodological limitations and results are exploratory. These user-reported experiences must thus be examined by well-designed and methodologically sound clinical or observational studies, particularly regarding CMP, where reports are very scarce.
PFAS and Potential Adverse Effects on Bone and Adipose Tissue Through Interactions With PPARγ

Published: September 2021

AbstractPerfluoroalkyl and polyfluoroalkyl substances (PFAS) are a widely dispersed, broad class of synthetic chemicals with diverse biological effects, including effects on adipose and bone differentiation. PFAS most commonly occur as mixtures and only rarely, if ever, as single environmental contaminants. This poses significant regulatory questions and a pronounced need for chemical risk assessments, analytical methods, and technological solutions to reduce the risk to public and environmental health. The effects of PFAS on biological systems may be complex. Each may have several molecular targets initiating multiple biochemical events leading to a number of different adverse outcomes. An exposure to mixtures or coexposures of PFAS complicates the picture further. This review illustrates how PFAS target peroxisome proliferator–activated receptors. Additionally, we describe how such activation leads to changes in cell differentiation and bone development that contributes to metabolic disorder and bone weakness. This discussion sheds light on the importance of seemingly modest outcomes observed in test animals and highlights why the most sensitive end points identified in some chemical risk assessments are significant from a public health perspective.

AbstractThis article discusses a 4-port micro-strip fed MIMO Antenna system with a triangular slot and an inverted L shape strip has been designed and analysed for both 2.3 GHz WiBro and Ultra-wide-band applications. The suggested antenna has been etched on a cost-effective epoxy (FR-4) substrate havingϵr${{\epsilon}}_{r}$ = 4.4 with an overall dimension of 45 × 45 × 1.6 mm3. Mutual coupling of −18 dB between the radiators has been obtained by orthogonal placement of radiators. From the simulated and practical results, the proposed compact MIMO system operates in frequency bands 2.26–2.42 GHz and 3.7–10.8 GHz respectively. The proposed small triangular MIMO system operates with an ECC less than 0.005 with an acceptable channel capacity loss <0.5 bits/s/Hz. Further, the diversity characteristics like DG, MEG, TARC, and group delay have been calculated and are presented in this paper.
Experimental and Numerical Investigation of the Surface Layer Conditions after Carbonitriding of Powder Metallurgical Steels. Part 2: Surface Layer States in Components of Graded Porosity

Published: September 2021

Abstract
Case hardening processes such as carbonitriding can be used to improve the performance of powder metallurgical (PM) structural components. The partially open porosity of these components leads to a significant increase in diffusion, which in turn leads to a change in the element gradient in the surface layer (and consequently the surface layer state) compared to melting metallurgic materials. Within the scope of a two-part work, the surface layer states in common densities are investigated after the case hardening process. The present part 2 comprises the characterisation of the resulting surface layer states depending on the carbon and nitrogen profile and the tempering heat treatment. Through the deep rolling and the subsequent carbonitriding treatment, hardness of up to 850 HV0.1, retained austenite contents of up to 25 vol-% and residual stresses of up to –300 MPa are determined across densities. The extensions to the numerical models described in this paper enable the FE model to predict the surface layer states in a wide range of process combinations and densities with an error tolerance of ±20 %.
Tribological Stress Behaviour of Cast Iron without and with Surface Treatment under Concentrated Contact Load*
Authors: Holst A. , Buchwalder A. , Zenker R. 
Published: September 2021

AbstractThe graphite inclusions typical of grey solidified cast iron materials reduce the load-bearing capacity under locally concentrated pressure and simultaneous sliding stress. Surface treatment processes such as nitriding and electron beam remelting are known to improve the local stress behaviour. In this paper, the effects of the above-mentioned individual processes and their combination on the tribological stress behaviour of ferritic and pearlitic cast irons with different graphite morphologies are discussed. The results obtained in the model wear test ball-plate show that the specific wear coefficient of the investigated cast irons with different graphite morphology can already be reduced by at least one order of magnitude by an approx. 0.5–0.9 mm thick remelted surface layer with a surface hardness of 650–750 HV1. This treatment eliminates the graphite and produces ledeburitic carbides instead. The potential of an additional nitriding treatment depends on the parameters used, i. e. the nitrided layer thickness produced as well as the phase composition and the pore fraction of the compound layer. Based on stress calculations, the experimentally determined main influences such as the coefficient of friction, the pore fraction in the compound layer and the magnitude of the Hertzian pressure on the contact stress could essentially be confirmed.

Published: September 2021

Abstract
Many studies about eTandem and language learning stem from learners in Western institutions of higher education. Unfortunately, there is a lack of research investigating the telecollaboration regarding language development between learners in the East and the West. Against this backdrop, a small-scale, six-week Chinese-English eTandem project focusing on learners’ language learning processes and experiences was undertaken between nine Chinese university students learning English in China and nine British university students learning Chinese in the UK. Multiple datasets were collected from learners’ diaries, synchronous Skype communication recordings, email exchanges, interviews and a post-project survey. This paper reports the main language error types made by Chinese L2 learners of English and error correction strategies provided by eTandem partners of competent L1 English speakers, along with how Chinese participants responded to the corrections. A thorough analysis of the research data indicated three types of linguistic errors in written tasks made by Chinese L2 learners of English: grammatical, lexical and idiomatic expressions. Another finding was that, although explicit written correction was the most commonly used strategy in email exchanges, learners preferred explanations with examples. In addition to previously established gains of eTandem learning, such as authentic communication, forging friendship and promoting intercultural awareness, positive responses to competent L1 partners’ error corrections was another major benefit indicated in our data. Our study pinpoints the importance of both pre-project training of participants on error-correction strategies with examples and how to respond to partner feedback in future eTandem projects.
Eyetracking a meeting of minds: teachers’ and students’ joint attention during synchronous online language tutorials
Authors: Shi Lijing , Stickler Ursula 
Published: September 2021

Abstract
The COVID-19 pandemic forced many language teachers to move their teaching online without sufficient preparation. This unexpected change of practice engendered doubt and anxiety in teachers. They worried about their ability to attract and hold their learners’ attention, an element that is essential for successful online teaching. Our dual-point eyetracking study looks into how students and teachers establish joint attention during online language tutorials. It also examines various means teachers employ to guide students’ attention and scaffold their meaning making process. The data was collected from two online language tutorials where the eye movement of one teacher and one student was tracked simultaneously, as well as recordings of their stimulated reflection while watching their own eyetracking visualisation replay. By combining mixed-method data and dual perspectives, we were able to unveil the complex interactions in online language tutorials and offer practical suggestions to language practitioners who hope to improve their online teaching skills.

Abstract

Objectives: Gordon syndrome (GS), also known as pseudohypoaldosteronism type II, is a rare tubular disease characterized by hypertension, hyperkalemia, and metabolic acidosis. Its causative genes are CUL3, KLHL3, WNK1, and WNK4, and they are associated with varying severity of the disease. Herein, we report the first case of GS caused by a CUL3 mutation in a patient with short stature in Korea.Case presentation: A 7-year-old boy had hypertension, metabolic acidosis, and persistent hyperkalemia, which were initially detected during the evaluation of short stature. He was born small for gestational age at late preterm gestation. Laboratory test findings showed hyperkalemia with low trans-tubular potassium gradient, hyperchloremic metabolic acidosis with a normal anion gap, and low plasma renin levels. Genetic analysis revealed a heterozygous de novo mutation in the CUL3 gene (c.1377+1G > C in intron 9). Thus, a diagnosis of GS was made. The results of the endocrine function test (including growth hormone stimulation tests) were normal. After thiazide treatment, the patient’s electrolyte levels were normalized. However, he presented with persistent hypertension and short stature.Conclusions: GS should be considered in children with short stature, hypertension, and hyperkalemia, and early treatment may reduce complications.

Published: September 2021

AbstractWe present initial exploratory work on illuminating the long-standing question of areal versus genealogical connections in South Asia using computational data visualization tools. With respect to genealogy, we focus on the subclassification of Indo-Aryan, the most ubiquitous language family of South Asia. The intent here is methodological: we explore computational methods for visualizing large datasets of linguistic features, in our case 63 features from 200 languages representing four language families of South Asia, coming out of a digitized version of Grierson’sLinguistic Survey of India. To this dataset we apply phylogenetic software originally developed in the context of computational biology for clustering the languages and displaying the clusters in the form of networks. We further exploremultiple correspondence analysisas a way of illustrating how linguistic feature bundles correlate with extrinsically defined groupings of languages (genealogical and geographical). Finally, map visualization of combinations of linguistic features and language genealogy is suggested as an aid in distinguishing genealogical and areal features. On the whole, our results are in line with the conclusions of earlier studies: Areality and genealogy are strongly intertwined in South Asia, the traditional lower-level subclassification of Indo-Aryan is largely upheld, and there is a clearly discernible areal east–west divide cutting across language families.
Exploitation, Trade Justice, and Corporate Obligations
Authors: Berkey Brian 
Published: September 2021

Abstract
In On Trade Justice, Risse and Wollner defend an account of trade justice on which the central requirement, applying to both states and firms, is a requirement of non-exploitation. On their view, trade exploitation consists in ‘power-induced failure of reciprocity’, which generates an unfair distribution of the benefits and burdens associated with trade relationships. In this paper, I argue that while there are many appealing features of Risse and Wollner’s account, their discussion does not articulate and develop the unified picture of states’ and firms’ obligations that they aim to provide as clearly as it might have. In particular, it is, I claim, unclear exactly how they understand the relationship between the fairness-based requirements that apply to states and those that apply to firms. I argue that there are two types of accounts that they might accept: a transactional account and a structural account. I offer reasons to think that there are reasons to prefer a structural account. In addition, I note some of the key implications of accepting such an account, and suggest that if Risse and Wollner accept these implications and revise other aspects of their view accordingly, the result is a plausible and unified account of what trade justice requires.
Multiobjective optimisation of flight paths for noise level mitigation and sound quality improvement
Authors: Centracchio Francesco , Burghignoli Lorenzo , Iemma Umberto 
Published: September 2021

AbstractThe present work deals with the multiobjective, multidisciplinary optimisation of takeoff and approach operations of a commercial aircraft aimed at the mitigation of the impact of aviation noise on the population. The innovative approach used here couples the minimisation of the aircraft noise level at the certification points with the improvement of the sound quality. The latter objective represents the main novelty of the present work and is addressed using a spectral–matching approach to make the aircraft noise as close as possible to a target sound. The rationale underlying the research is the development of a community–oriented approach to the assessment airport operations in view of the complete redefinition of the future airport scenarios. Indeed, the air traffic growth, the rapid expansion of urban areas around airports, and the expected advent of urban air mobility, are transforming the aviation noise into a serious hazard to the sustainable development of society. The sound–quality–based objective imposes a comprehensive multidisciplinary approach also in the procedural optimisation, due to the detail required to estimate the noise spectrum composition. Two merit factors are minimised, specifically the EPNL at the noise certification points and theLp–norm of the difference between the noise produced by the configuration under analysis and a target sound. The target sounds are obtained by using sound engineering techniques aimed at the sound quality improvement, on the basis of the results of the psychometric tests campaigns performed within the projects SEFA and COSMA. The minimisation is achieved adopting a global evolution method, and the results are presented in terms of approximated Pareto frontiers for a single–aisle aircraft in both takeoff and landing conditions.

Abstract
Early diagnosis of cancer has become one of the effective ways to prevent and treat cancer. At present, magnetic resonance imaging (MRI) diagnosis based on nanosized iron oxide with no toxicity and excellent biocompatibility has attracted much attention. But the poor stability of magnetic fluid (MF) is becoming more and more prominent. In view of the poor stability of MF, the dodecanethiol-poly(methacrylic acid) (DDT-PMAA) as an outer shell was prepared for the MFs (Fe3O4@DDT-PMAA MF) to improve the stability. We also compared the amount of reactants, the ratio of reactants, and the reaction temperature, and finally screened out the best reaction conditions, so as to get more stable products. The stability of the system was studied by visual observation, stability index (I), and magnetic weight change. The results demonstrated that Fe3O4@DDT-PMAA can be stable for more than 60 days. The T
1 mapping image showed that the longitudinal relaxivity (r
1) value was 6.9 mM−1 s−1 (1.5 T, room temperature), which was higher than the commercial contrast agent SHU-555 (r
1 = 2.9 mM−1 s−1), but the transverse relaxivity (r
2) value accounted for 64.48% of the commercial contrast agent Feridex (r
2 = 67.8 mM−1 s−1, 1.5 T, room temperature) because the outermost layer was encapsulated by a polymer. In addition, the imaging effect was more vivid and there was almost no background interference of T
1- and T
2-weighted images in vivo, which indicated that the Fe3O4@DDT-PMAA MF exhibited excellent potential in MRI applications.
