Fragmented psyche and postcolonial feminist construction: A study of Emeka Nwabueze’s The dragon’s funeral and tess Onwueme’s Then she said it
Authors: Yong Walters Ncham 
Published: November 2022

This paper focuses on memory fragmentation as a result of gender relations between sexes that leads to trauma. A reading of Emeka Nwabueze’s The Dragon’s Funeral and Tess Onwueme’s Then She Said It reveals that patriarchy plays a negative role on both male and female genders and this places the study to hinge on the assumption that the dramatic world of Nwabueze and Onwueme is a patriarchal constructed society where both male and female genders suffer marginalization and look forward for liberation. This brings to focus the fragmentation of the psyches of both genders as a result of the traumatic experiences which they encounter in the process of patriarchal resistance and subordination. The study uses postcolonial feminism and psychoanalysis as its theoretical standpoint to demonstrate the oppressive nature of patriarchy on both genders which affects their psyches negatively in a society that subordinates women as well as men. It further underscores that the stereotypical perception of both gender acts also reinforces the fragmentation of psyches of women and men, thus revealing the mechanism of gender inequality that results in the fragmentation of the psyches of women and men as human beings who are constructed to speak in silence. The study, however, concludes that forms of patriarchal oppression, exploitation and subordination greatly contribute to the dissociation of the memories of victims of patriarchy and oppression as a result of trauma.
Lexico-stylistic analysis of Facebook postings on COVID-19 pandemic
Authors: Damkor Torkuma Tyonande 
Published: November 2022

COVID-19 has been a global menace, hence a lot of awareness is being created in order to defeat the global menace and this awareness is carried out through language. Previous studies exist on lexico-stylistic analysis and the most related one to the present study is the stylistic analysis of a selected election campaign speech of President Goodluck Jonathan. The study looks at the use of words in utterances and their effect in the speech from the lexical, figure of speech, cohesion and context categories perspectives. This current study differs from the previous study because it is not about an election campaign speech but rather it is centred on the role of language in fighting COVID-19 by examining Facebook postings through a lexico-stylistic approach. The study is anchored on the Linguistic and Stylistic Categories by Leech and Short. The survey design was used for the study and data for the study were collected by extracting postings on COVID-19 from the Facebook and this was limited to selected Facebook posts of June and July, 2021 due to time and financial constraints. The findings of the study show that COVID-19 postings on the Facebook are majorly characterised by simple words or words without affixation. They also show that medical registers, figures of speech and collocations are featured in the Facebook postings on COVID-19.
Welding Properties of Titanium Alloys Grade 5
Authors: Farrokhi Alireza 
Published: November 2022

Titanium alloys have attractive properties that have been widely used in various fields due to these properties. The biocompatibility of titanium has caused its usages in the pharmaceutical industry. Its good corrosion resistance has resulted in its many applications in petrochemical and marine industries. Meanwhile, the most important and major application of titanium and its alloys can be found in the aerospace industry in a variety of spacecraft, space rockets, and satellites. The most important reason for the widespread use of these alloys in the aerospace industry is the high ratio of strength to their weights. However, the most important factor limiting the usage of titanium and its alloys is its high price. In this chapter, we first introduced titanium and its alloys. Then, according to mainstream of the design, titanium alloy bonding methods and welding problems have been investigated. The purpose of this study is to investigate the processes of arc welding of tungsten electrode-neutral gas with different alloy heat inputs for a titanium alloy of Ti-6Al-4 V and to provide comprehensive welding instructions. So, after introducing the pure commercial titanium properties, we examined the properties, specifications and welding of Ti-6Al-4 V. Given the focus on the mentioned process, the generalities of this welding process have been described.

Published: November 2022

Carbon quantum dots (CQDs) are emerging as promising materials for applications like flexible or transparent solar cell, white light emitting diodes (WLEDs), etc. due to their low cost, eco-friendliness, substantial absorption coefficient, wide absorption spectrum, tuneable optical properties, good charge transfer/separation ability, good quantum yield and large two-photon absorption cross-section. They have been employed in solar cells as active absorbing layers, electron acceptors/donors, electron sinks, electron transporting layers (ETL), hole transporting layers (HTLs), dopants, and interlayer spacing. Consequently, such solar cells have exhibited enhanced performance. In contrast to commercial rare-earth phosphors and traditional semiconductor quantum dots (SQDs) (usually toxic), CQDs exhibit wide range of emission characteristics [full width half maxima (FWHM) > 80 nm]. Interestingly, the emission characteristics of these nanomaterials are tuneable which makes them suitable for WLEDs applications. Red-CQDs are gaining importance as they are required to realize the warm WLEDs. Though a lot of work has been done to modulate the properties of CQDs in order to enhance the performance of solar cells and WLEDs, there are immense possibilities to further exploit the potential of CQDs in these applications.

Silicon photonics is one of the promising technologies for high-speed optical fiber communications. Among various silicon photonic devices, germanium on silicon avalanche photodiode (Ge/Si APDs) received tremendous attentions because of its superior performance and integration compatibility. In 2016, normal incidence Ge/Si APD demonstrated a NRZ 10−12 sensitivity of −23.5 dBm at 25 Gb/s; more recently, a waveguide-integrated Ge/Si APD receiver presents a 106Gb/s PAM4 sensitivity of −18.9 dBm. These results are best reported performance among all APD-based devices, and these breakthroughs are mainly benefited from Ge/Si APD’s structure and material characteristics. Ge/Si APD adopts a separated charge-absorption-multiplication (SCAM) structure with a pure Ge absorber and an intrinsic Si avalanche layer. Since, Si is one of well-known best avalanche materials with large gain-bandwidth products and low ionization noise ratio, which make Ge/Si APDs demonstrating superior performance at high data rates. Moreover, this Si-based device is manufactured by standard CMOS foundries and is process-compatible with other silicon photonic devices including silicon-based waveguides, demux, hybrid, etc. This advantage simplifies the assembly of photonic systems and makes a large-scale integrated silicon photonic chip possible, which provides compact solutions for high-density communication systems. In this chapter, we review recent progresses on Ge/Si APD structure design, material, and performance.

Authors: Cristina Russu Manuela 
Published: November 2022

High rate complications and recurrences in reconstructive surgery using in situ synthetic/polypropylene (PP) meshes have driven to a new concept based on mesenchymal stem cells (MSCs) for homeostasis repair in pelvic floor disorders (PFD). Prevention and therapy with MSCs are up to date analyzed on small and large animal models, less in women trials. Cell based-vaginal/intraurethral, or systemically introduced, tissue engineering (TE) with new generation meshes/scaffolds MSCs seeded-bone marrow, adipose tissue and recently proposed the endometrial/menstrual MSCs (eMSCs/MenSCs) for PFDs, management. Easy collected, isolated with specific markers, cultured for number harvesting, without ethic and immune compatibility issues, with unique biologic properties eMSCs/MenSCs differentiate in many cellular types—smooth muscle, and fibroblast-like cells, preserving cell shape, and phenotype, without oncogenic risks, and collagen, elastin fibers; eMSCs/MenSCsare appropriate for PFDs management, respecting good protocols for human safety. The quick appeared regenerative effect-mediated by angiogenesis, apoptosis inhibition, cell proliferation, no chronic inflammation and low/no foreign body reactions, less thick collagen fibers, and fibrosis improve connective/neuromuscular tissues; less pelvic structures stiffness with more elasticity are advantages for new meshes/scaffolds generation in TE. Human eSMCs/MenSCs deliver bioactive factors by their exosomes/microvesicles/secretome for paracrine effects to injury site, facilitating in vivo tissue repair.

Survey of bats on the south coast and ranges of the Shoalhaven region in New South Wales
Authors: Daly Garry , Hoye Glenn 
Published: November 2022

ABSTRACT
Surveys for echolocating bats were conducted primarily by harp trapping and echolocation detection in the Shoalhaven region on the south coast region of New South Wales from 1989 to 2021. A total of 399 sites were surveyed by harp trapping and 175 sites through echolocation call detection. Mist nets were used to catch bats at one site in 1989. The survey covered a range of vegetation communities at altitudes that ranged from near sea level to 770m asl. One hundred and seventy-four harp trap sites were within conservation reserves/state forests and the rest were on freehold land. Each site was trapped from 1 - 4 nights for a total of 666 harp trap nights. Sites surveyed electronically were sampled between 1- 2 nights for a total of 230 samples of either 30 minutes duration or an entire night. A total of 18 species were captured in harp traps during the survey. The Yellow-bellied Sheath-tailed Bat Saccolaimus flaviventris was observed once during spotlight surveys and detected electronically. The White-striped Free-tailed Bat Austronomus australis was heard echolocating at night and detected electronically. The Little Bent-wing Bat Miniopterus australis was only detected electronically. The highest capture rate was in Jerrawangala National Park where 38 animals consisting of five species were trapped in one trap on a single night. The highest species richness and density was found in tall open forests, especially those along the Illawarra escarpment. Analysis of abundances found that the Little Forest Bat Vespadelus vulturnus was the most common species accounting for 45% of animals trapped. Seven species currently listed under the Biodiversity Conservation Act (2016) were caught and another detected electronically. Those trapped were the Large-eared Pied Bat Chalinolobus dwyeri, Eastern Falsistrelle Falsistrellus tasmaniensis, Golden-tipped Bat Phoniscus papuensis, Eastern Bent-wing Bat Miniopterus orianae oceanensis, Eastern Coastal Free-tailed Bat Micronomus norfolkensis, Large-footed Myotis Myotis macropus and Greater Broad-nosed Bat Scoteanax rueppellii. In addition, the regionally rare Ride’s Free-tailed Bat Ozimops ridei was trapped. The survey provided the first live specimens of Eastern Forest Bat V. pumilus in the south coast region, a range extension of some 260km south of the previous accepted records in the Watagan Mountains. The capture of a Large-eared Pied Bat at Meroo NP represents a southern range extension for this species. Morphometric data are presented plus comments on species habitat preference.

Published: November 2022

AbstractMassage RNA (mRNA) vaccines represent a new strategy for advanced cancer immunotherapy. To protect mRNA from degradation and deliver to targeted cells, lipid nanoparticles (LNPs) are extensively utilized as non‐viral vectors. However, the stability of mRNA‐laden LNPs substantially hinders their clinical application. Development of thermostable and durable mRNA nanovaccines is urgently needed. Here, a hyaluronan dynamic hydrogel is reported to protect mRNA and resiquimod (R848)‐laden LNPs (HA‐mRLNPs) from degradation at room temperature for durable cancer immunotherapy. A microfluidic device is proposed to effectively encapsulate mRNA and immunoadjuvants in LNPs (mRLNPs). Then, hyaluronan dynamic hydrogel is used to stabilize LNPs during storage at room temperature by restricting the migration and fusion of LNPs. Particularly, gel‐like hyaluronan undergoes state transition for controlled release of mRLNPs under physiological condition. Therefore, HA‐mRLNPs can efficiently deliver mRNA encoding tumor antigens to dendritic cells for antigen presentation to induce antigen‐specific CD8+ T cells for killing tumor cells. Overall, this study demonstrates that the LNPs‐hydrogel system can be used for effective cancer immunotherapy.
Self‐Sustained Snapping Drives Autonomous Dancing and Motion in Free‐Standing Wavy Rings

Published: November 2022

AbstractHarnessing snapping, an instability phenomenon observed in nature (e.g., Venus flytraps), for autonomy has attracted growing interest in autonomous soft robots. However, achieving self‐sustained snapping and snapping‐driven autonomous motions in soft robots remains largely unexplored. Here, harnessing bistable, ribbon ring‐like structures for realizing self‐sustained snapping in a library of soft liquid‐crystal elastomer wavy rings under constant thermal and photothermal actuation are reported. The self‐sustained snapping induces continuous ring flipping that drives autonomous dancing or crawling motions on the ground and underwater. The 3D, free‐standing wavy rings employ either a highly symmetric or symmetry‐broken twisted shape with tunable geometric asymmetries. It is found that the former favors periodic self‐dancing motion in place due to isotropic friction, while the latter shows a directional crawling motion along the predefined axis of symmetry during fabrication due to asymmetric friction. It shows that the crawling speed can be tuned by the geometric asymmetries with a peak speed achieved at the highest geometric asymmetry. Lastly, it is shown that the autonomous crawling ring can also adapt its body shape to pass through a confined space that is over 30% narrower than its body size.

AbstractThe practical application of the room‐temperature sodium–sulfur (RT Na–S) batteries is hindered by the insulated sulfur, the severe shuttle effect of sodium polysulfides, and insufficient polysulfide conversion. Herein, on the basis of first principles calculations, single‐atom vanadium anchored on a 3D nitrogen‐doped hierarchical porous carbon matrix (denoted as 3D‐PNCV) is designed and fabricated to enhance sulfur reactivity, and adsorption and catalytic conversion performance of sodium polysulfide. The 3D‐PNCV host with abundant and active V sites, hierarchical porous structure, high electrical conductivity, and strong chemical adsorption/conversion ability of V–N bonding can immobilize the polysulfides and promote reversibly catalytic conversion of polysulfides toward Na2S. Therefore, as‐fabricated RT Na–S batteries can achieve a high reversible capacity (445 mAh g−1 over 800 cycles at 5 A g−1) and excellent rate capability (224 mAh g−1 at 10 A g−1). The electrocatalysis mechanism of sodium polysulfides is further experimentally and theoretically revealed, which provides a new strategy to develop the highly stable RT Na–S batteries.

Published: November 2022

AbstractOur efforts as a society to combat the ongoing COVID‐19 pandemic are continuously challenged by the emergence of new variants. These variants can be more infectious than existing strains and many of them are also more resistant to available vaccines. The appearance of these new variants cause new surges of infections, exacerbated by infrastructural difficulties, such as shortages of medical personnel or test kits. In this work, a high‐resolution computational framework for modeling the simultaneous spread of two COVID‐19 variants: a widely spread base variant and a new one, is established. The computational framework consists of a detailed database of a representative U.S. town and a high‐resolution agent‐based model that uses the Omicron variant as the base variant and offers flexibility in the incorporation of new variants. The results suggest that the spread of new variants can be contained with highly efficacious tests and mild loss of vaccine protection. However, the aggressiveness of the ongoing Omicron variant and the current waning vaccine immunity point to an endemic phase of COVID‐19, in which multiple variants will coexist and residents continue to suffer from infections.

Abstract5‐Amino‐4‐imidazolecarboxamide‐ribosiduria (AICA‐ribosiduria) is an extremely rare inborn error of purine biosynthesis metabolism caused by pathogenic variants in ATIC gene that encodes a protein catalyzing the last steps of the de novo purine biosynthesis. To date, only six cases have been reported presenting a severe phenotype characterized by coarse facies and variable dysmorphic features, intrauterine and postnatal growth retardation, severe and early neurodevelopment delay, profound congenital visual deficit, scoliosis and, less frequently, epilepsy, aortic coarctation, chronic hepatic cytolysis, nephrocalcinosis and mild genitalia malformation. In this article, we report two new cases of AICA‐ribosiduria carrying new pathogenic variants in ATIC (c.421C>T;p.Arg141Ter and c.1753A>G p.Thr585Ala) associated to a milder phenotype compared to previously reported patients. Particularly, the children showed few dysmorphic features (bulging forehead, depressed nasal bridge, and flat nasal tip), postnatal growth impairment, psychomotor delay since the second year of life, reduction of visual acuity (from mild impairment to low vision from the age of 5 years and to partial blindness from the age of 7 years) and mild hepatic dysfunctions. Scoliosis as well as epilepsy, renal involvement, or genitalia malformation were not detected. According to literature data, we found an abnormal accumulation of intermediates of de novo purine biosynthesis in the urine of both siblings. This report expands the spectrum of phenotypic severity associated to ATIC biallelic pathogenic variants and prompts the need to investigate ultra‐rare causes of metabolic disorders such as AICA‐ribosiduria in subjects with early neurological and sensory involvement of uncertain etiology.

AbstractIntroductionSleep disruption is associated with astrocyte activation and impaired cognition in model organisms. However, the relationship among sleep, astrocyte activation, and cognition in humans is uncertain.MethodsWe used RNA‐seq to quantify the prefrontal cortex expression of a panel of human activated astrocyte marker genes in 1076 older adults in the Religious Orders Study and Rush Memory and Aging Project, 411 of whom had multi‐day actigraphy prior to death. We related this to rest fragmentation, a proxy for sleep fragmentation, and to longitudinal cognitive function.ResultsFragmentation of rest periods was associated with higher expression of activated astrocyte marker genes, which was associated with a lower level and faster decline of cognitive function.DiscussionAstrocyte activation and fragmented rest are associated with each other and with accelerated cognitive decline. If experimental studies confirm a causal relationship, targeting sleep fragmentation and astrocyte activation may benefit cognition in older adults.Highlights
Greater fragmentation of rest periods, a proxy for sleep fragmentation, is associated with higher composite expression of a panel of genes characteristic of activated astrocytes.
Increased expression of genes characteristic of activated astrocytes was associated with a lower level and more rapid decline of cognitive function, beyond that accounted for by the burden of amyloid and neurofibrillary tangle pathology.
Longitudinal and experimental studies are needed to delineate the causal relationships among sleep, astrocyte activation, and cognition.
