Abstract
Within the eastern portion of the Carletonville gold field, the gold- and uranium-rich Carbon Leader reef of the Central Rand Group (Witwatersrand Supergroup) is truncated by an erosion channel. This channel is asymmetrical and lenticular in shape, measuring 150 to 180 m in width and up to 100 m in depth. High-resolution seismic data show that the erosion channel cuts from the Carbon Leader reef into all older units of the Central Rand Group down to the Roodepoort Formation of the underlying West Rand Group. A total of seven boreholes were drilled into the channel, revealing that it is composed of quartzite at its base (9 m thick), overlain by deformed (lower) and laminated (upper) chloritoid-bearing shale (21 m thick) and quartzite (18 m thick). The Carbon Leader reef is highly enriched in gold (5–40 g/t Au), whereas the gold tenor of the erosion channel fill is in general much lower (&lt;1 g/t Au), although locally grades of as much as 3.8 g/t Au are reached. Detailed seismic, sedimentological, and petrographic analyses revealed that the channel was filled with locally sourced sediments from the Main Formation. A closed-system mass balance further demonstrates that gold in the erosion channel could have been entirely sourced from the Carbon Leader reef. Sediment load played a crucial role in the distribution of gold in the channel, thus supporting a stratigraphically controlled modified placer model for the origin of gold in the Carbon Leader reef.
Serviceability fragility functions for New Zealand residential windows
Authors: Carradine David , Kumar Aman , Fairclough Roger , Beattie Graeme 
Published: September 2020

Glazing and window systems in New Zealand have been shown to be susceptible to significant damage as evidenced by the past decade of earthquakes. The seismic performance of glazing and window systems has resulted in considerable financial loss, disruption in business and physical injuries following earthquakes. In order to investigate the vulnerability of residential windows in typical light timber framed buildings racking testing was conducted on six wall configurations. Numerous observations of window performance were made during the testing and from these results fragility functions were developed for timber and aluminium framed windows. These fragility functions suggest that even at low displacement levels damage can occur to windows that can potentially affect weather-tightness and require repairs following an earthquake. These functions can inform decisions around designing for resiliency in residential structures in New Zealand.

Published: September 2020

Aims: To promote the rational exploration of the mushroom resources, this study evaluated the in vitro antioxidant activity of 16 kinds of mushrooms collected from the Sichuan province in China and completed the identification of the optimal active strains.
Place and Duration of Study: School of Life Science and Engineering, Southwest University of Science and Technology, Mianyang, Sichuan province, China. April 2019 to May 2020 (13 Months).
Methodology: 16 kinds of mushrooms were collected in the wild. These strains were isolated and cultivated. The extract’s antioxidant activities of fermentation broth and mycelium were assessed using the DPPH radical-scavenging method. The higher activity strains were also evaluated by Trolox equivalent antioxidant capacity (TEAC) and the Ferric reducing antioxidant power (FRAP) assay. Meanwhile, the contents of total flavonoids and total phenols were determined. Finally, The highly active strains were identified by internal transcribed spacer (ITS) Identification.
Results: All extract of fermentation broth and mycelium from 16 kinds of mushrooms had scavenging effects on DPPH. Among them, strain No. 6 and No. 7 exhibited obvious antioxidant capacity, and the scavenging rates of their fermentation broths on DPPH were 89.47% and 84.27%, respectively. And the results of TEAC and FRAP were consistent with those of DPPH. Besides, these two kinds of mushrooms were all rich in phenolic and flavonoid compounds, and the content in the fermentation broth was significantly higher than that in the mycelium, indicating that phenolic and flavonoid substances may be the material basis of their antioxidant effect. The strain No. 6 and No. 7 were confirmed to be Bjerkandera and Nigrospora sp, respectively by 16S nrDNA sequence identification.
Conclusion: The results showed that Bjerkandera and Nigrospora sp. possessed the highest antioxidant capacities with rich total phenolic and total flavonoids. They could be potential sources of natural antioxidants for further exploration and application.

Published: September 2020

Aims: This study was carried out to investigate the comparative seroprevalence and associated risk factors of toxoplasmosis among four subgroups in Port Harcourt viz: immunocompromised persons (HIV), pregnant women (PTW) and schizophrenics (SZN), using immunocompetent persons (IP) as controls.
Study Design: A descriptive cross-sectional study was adopted.
Place and Duration of Study: The study was carried out in the University of Port Harcourt Teaching Hospital (UPTH), Braithwaite Memorial Specialist Hospital (BMSH) and Neuro Psychiatric Hospital (NPH) between March 2016 and February 2017.
Methodology: A total of 800 (200 from each of the group) samples were collected from subjects from the three hospitals. Study participants of ≥20 years were used in this study. The detection of T. gondii antibodies in examined sera was carried out using ELISA –IgG and IgM assay using standard procedures. Structured questionnaires were used to collect data on social demographic risk factors associated with toxoplasmosis.
Results: Out of the 800 (200 per group) examined, SZN recorded the highest seroprevalence of IgG 50%(100)(P.= .05) and IgM 4%(8) followed closely by HIV subjects with seroprevalence of IgG 32%(72) (P=.05) and IgM 2%(3). However, the seroprevalence were not significantly different from that of the immunocompetent control group which had the least seroprevalence. Schizophrenia subjects in age group 20-24 years recorded the highest seroprevalence with (P=.05) The unemployed recorded the highest seroprevalence for SZN with rates of 43% for IgG. More males were infected with the disease than females. Male Schizophrenics recorded a seroprevalence of 20.9%. There was no significant relationship between seroprevalence and demographic factors among subjects.
Conclusion: Our findings indicated that toxoplasmosis was relatively prevalent (P=.05) among the studied population, with schizophrenics having the highest seroprevalence. Therefore, incorporating detection of anti-Toxoplasma antibodies in routine testing in our health care centers is recommended for monitoring and control of the disease.
Multicompartment Microreactors Prevent Excitotoxic Dysfunctions In Rat Primary Cortical Neurons

Published: September 2020

AbstractExcitotoxicity is a cellular phenomenon that comprises the consequences of toxic actions of excitatory neurotransmitters, such as glutamate. This process is usually related to overproduction of reactive oxygen species (ROS) and ammonia (NH4+) toxicity. Platinum nanoparticle (Pt‐NP)‐based microreactors able to degrade hydrogen peroxide (H2O2) and NH4+, are previously described as a novel therapeutical approach against excitotoxicity, conferring protection to neuroblasts. Now, it is demonstrated that these microreactors are compatible with rat primary cortical neurons, show high levels of neuronal membrane interaction, and are able to improve cell survival and neuronal activity when neurons are exposed to H2O2 or NH4+. Additionally, more complex microreactors are assembled, including enzyme‐loaded liposomes containing glutamate dehydrogenase and glutathione reductase, in addition to Pt‐NP. The in vitro activity of these microreactors is characterized and they are compared to the Pt‐NP‐based microreactors in terms of biological activity, concluding that they enhance cell viability similarly or more extensively than the latter. Extracellular electrophysiological recordings demonstrate that these microreactors rescue neuronal functionality lost upon incubation with H2O2 or NH4+. This study provides more evidence for the potential application of these microreactors in a biomedical context with more complex cellular environments.

Published: September 2020

AbstractObjectivesThe objective was to develop an odontometric technique for sex estimation based on dental measurements from adult individuals, and to evaluate its applicability and reliability for diagnosis of sex of nonadult skeletal remains.Materials and methodsThis study was conducted on the permanent dentition of 132 individuals (70 males, 62 females) from the identified human skeletal collection of the Certosa Cemetery (Bologna, Italy) of the University of Bologna. Binary logistic regression equations were developed based on dental measurements of the permanent teeth of the adult individuals, and these equations were subsequently applied to the permanent dentition of nonadult individuals to estimate their sex.ResultsThese data show that the canine teeth of both the maxilla and mandible are the most sexually dimorphic teeth in adults, followed by the mandibular second molar, maxillary and mandibular second and first premolars, and mandibular first molar. These data provided correct assignment of sex in 80.4–94.9% of cases, which depended on the measurements used. Of the 26 nonadult individuals of the experimental sample, sex diagnosis was possible for 22, which represented an applicability rate of 84.6% of the individuals. Comparing the sex of these 22 nonadult individuals estimated by odontometrics with the known biological sex, correct assignment was obtained in 90.9% of cases.ConclusionAs a method of sex estimation, odontometric analysis of permanent dentition can be used successfully for nonadult human skeletal remains in both forensic and archeological contexts.

Published: September 2020

AimIn patients with thunderclap headaches, reversible cerebral vasoconstriction syndrome (RCVS) should be considered as a differential diagnosis. However, RCVS diagnosis in the emergency department (ED) remains challenging. This report describes the clinical features and factors related to RCVS diagnosis and suggests diagnostic strategies for its management.MethodsWe retrospectively reviewed the medical records of eight patients diagnosed with RCVS from January 2010 to March 2019 (aged 18–69 years, 5 women).ResultsThe median duration from the ED visit to RCVS diagnosis was 6 days (range, 1–11 days). Of the eight patients, seven were middle‐aged, six had apparent triggers, six had subarachnoid hemorrhage (SAH), five had high systolic blood pressure, and none had any specific abnormality observed upon physical examination. At the initial visit, RCVS was diagnosed in only one patient who had a history of RCVS. Of the other patients, SAH was diagnosed in two, and primary headache was diagnosed in four patients with negative computed tomography (CT) findings. Based on follow‐up angiography (e.g., magnetic resonance angiography), seven of eight patients with convexal SAH were diagnosed with RCVS (as the cause of SAH).ConclusionReversible cerebral vasoconstriction syndrome with negative CT findings at the ED visit was likely to be misdiagnosed as a primary headache. In patients with thunderclap headache and negative CT findings, physicians should consider RCVS as a differential diagnosis, inform patients of the risk of RCVS, and undertake follow‐up imaging within 2 weeks.
S‐parameters, electrical permittivity, and absorbing energy measurements of carbon nanotubes‐based composites in X‐band
Authors: da Silva Valdirene Aparecida , Rezende Mirabel Cerqueira 
Published: September 2020

AbstractComposites based on carbon nanotubes (CNT) have recently received great attention as a possible new generation of radar absorbing materials (RAM), due to their efficient microwave attenuation capacity and low density. However, RAM performance can vary significantly depending on the CNT being used. Aiming to directly show the influence of CNT from two different suppliers, both multi‐walled and non‐functionalized (CNT‐B and CNT‐K), the electromagnetic behaviors of RAM processed in epoxy resin are compared. Scattering parameters (S‐parameters), complex electrical permittivity and magnetic permeability, and absorbed energy of the composites in the X‐band (8.2–12.4 GHz) are evaluated. The results clearly show the influence of the two different CNT on the electromagnetic characteristics of composites. CNT‐B based composites behave as broadband RAM with the tendency of better attenuation results above 12.4 GHz. On the other hand, CNT‐K based composites show good attenuation results in the X‐band (>99%). Undoubtedly, the results confirm that the longer length of CNT‐K favored the interconnection among the filaments, as well as, the formation of compact agglomerates surrounded by resin rich regions, which favored the impedance matching and mechanisms of losses in the processed RAM.

Published: September 2020

AbstractThis qualitative study explores the experiences of the managers and employees of electrical and electronics companies in moving towards environmental sustainability with the support of Green Human Resource Management. Based on 12 in‐depth interviews, the data were thematically analysed by using NVivo 12 plus software, with three main themes emerging as embarking on environmental sustainability, building environmental sustainability, and embracing environmental sustainability. This study uses the resource‐based theory as the theoretical lens, and results indicate that the company practises Green Human Resource Management, particularly green employee involvement and participation, green training, green rewards, and green orientation for achieving its environmental sustainability efforts. Most importantly, the results highlight that NGOs, organisational culture, and effective communication are vital in supporting Green Human Resource Management implementation in attaining environmental sustainability goals. The findings of this study have implications for other developing countries, which are striving to achieve their environmental and sustainability goals.
