Upscaling of 500 °C Durable SiC JFET-R Integrated Circuits

At HiTEC 2018, NASA Glenn Research Center reported the first demonstration of yearlong 500 °C operation of ceramic-packaged “Generation 10” ~200-transistor integrated circuits (ICs) based on two-level interconnect silicon carbide (4H-SiC) junction field effect transistors and resistors (JFET-R). This HiTEC 2021 submission updates on-going efforts at NASA Glenn spanning two subsequent prototype IC generations “11 and 12” to increase both complexity and durability of these ICs. Increased chip complexities of around 1000 transistors/chip for Gen. 11 and near 3000 transistors/chip for Gen. 12 are made possible by reductions in minimum layout feature sizes (including resistor width shrinkage from 6 μm to 2 μm) coupled with enlarged die size (from 3 × 3 mm to 5 × 5 mm). Gen. 11 ICs electrically tested to date include an 8-bit delta-sigma analog to digital converter (ADC) as well as upscaled random access memory (RAM) and nearly 1 kbit read only memory (ROM). However, Gen. 11 prototype ICs exhibited significantly lower yield and durability than Gen. 10 ICs. Development of revised processing is being investigated towards mitigating these issues in subsequent Gen. 12 fabrication run currently in progress.

P-value 1.6, p-value<0.05). Conclusion: NaPB enhanced the cytotoxicity of conventional chemotherapy against colorectal cancer cell lines harboring wild-type or mutant p53. Thus NaPB is a promising potential adjuvant chemotherapy in colorectal cancer.
Land-Use Is More Important Predictor of Native Abundance and Diversity Than Invasive Tithonia Diversifolia - Evidence From a Tropical Savanna

Invasive alien species (IAS) and land-use represent major threats to native plant communities around the globe. However, studies on IAS and potential ecological impacts in the context of land-use are limited in sub-Saharan Africa. Using a set of 45 plots in Jos metropolis in central Nigeria, we assessed the abundance of invasive Tithonia diversifolia (Hemls.) A. Gray, and its relationship with abundance and diversity of native plant species among land-use types. Abundance of T. diversifolia was the highest in farmland when compared to riparian and roadside land-use types. Also, the abundance and diversity of native species were lowest in farmland when compared to the roadside and riparian plant communities with increased T. diversifolia abundance. We showed that while T. diversifolia has low impact on native species, land-use type is an important predictor of native abundance and diversity. Although T. diversifolia has benefitted from the disturbances across land-use types, we found a very weak negative estimate of T. diversifolia effects on native species. These results consolidate existing evidence that land-use transformation in sub-Saharan Africa provides opportunities for alien plant invasion and native species decline. More important is the preservation of land-use types, which will result in a synergy of conservation effort - both reducing T. diversifolia abundance and preserving native plant abundance and diversity in central Nigeria.
What Do Team Coaches Experience at the End of a Client Relationship

All coaching and business relationships have an ending. Here we explore the reflections of experienced team coaches at this key stage of the client relationship. This is where coaches consider the choices they have made, how they responded to the client, their relationship to the wider organisation and the other key stakeholders. By seeking to explore how seasoned coaches interpret their experiences, we gain a window into how they have developed a mastery of their craft. Using an IPA methodology, this study contributes to evidence-based research in the discipline, practice, and purpose of systemic team coaching. This paper includes a literature review tracking the evolution of systemic team coaching as a discipline, relevant social science, and business management research. The methodology provides an overview of the design process, sampling, and data collection also a diagrammatic overview of the core elements of Interpretative Phenomenological Analysis (IPA). The findings give a voice to the coaches themselves. The analysis and discussion are divided into three core themes: The Team Coach in the Field; The Team Coach as Guide; The Team Coach Withdrawal. The conclusion explores the implications for contracting, practice, coach development and reflexivity.
Evaluation of the compressive strength of commercial sandcrete blocks produced in two metropolises of Delta State, Nigeria

The mechanical properties of sandcrete block greatly influenced the durability of structures built from it. This study was carried out to assess the compressive strength of sandcrete blocks produced in two major developmental and rapidly urbanizing zones of Delta State, Nigeria. 150 and 225 mm sandcrete blocks were sampled from 18 blocks moulding factories in Ndokwa East and Ughelli North Local Government Areas of Delta State, Nigeria. Five sandcrete block was sampled from each block moulding factory, at the rate of 9 factories per Local Government Area. The compressive strength of the sampled blocks was determined in accordance with the ASTM International standards. The results of compressive strength test showed that the compressive strengths of the blocks, regardless of the block size ranged from 0.61 to 16.19 MPa. Analysis of the results revealed that apart from the customized blocks, the compressive strengths of all the other blocks fell below the Nigerian Industrial Standard (NIS) recommendations of 2.5 MPa for non-load bearing walls. The general poor quality of the sandcrete blocks is attributed particularly to the poor mix ratios adopted by the block producers which fell short of NIS recommendations. Thus, this study recommended that standard regulatory agencies should closely monitor all the block making factories in the state, to ensure that sandcrete blocks produced or brought into the state met NIS recommendations
The Stepping into Visibility Model: reflecting on consequences of social media visibility – a Global South perspective

ABSTRACT This article discusses activists’ need to reflect on how achieving social media visibility might translate into vulnerability. In order to provide activists with a tool for this reflection, the Stepping into Visibility Model has been developed and applied to two case studies: (a) an activist group in a Brazilian favela using social media for protection against police brutality and (b) a Kenyan photographer, affiliated to an art-ivist (artistic and activist) collective, producing images of Nairobi at night to tackle social anxiety issues. The research draws from sociological insights on the concept of ‘visibility’ and adopts a case study methodology combined with ethnographic approaches. By adopting a Global South perspective, it discusses counter surveillance efforts in ways that go beyond techno-legal solutionism (Dencik et al, 2016) and in periods outside that of big-scale protests (McCosker, 2015). By devising this model, we hope to offer a contribution on how marginalised communities can be better informed when they encounter unintended negative visibility.
Effects of aqueous leaf infusion of Pterocarpus santalinoides DC on the serum lipid profile of guinea pigs (Carvia porcellus)

AIM: This study investigated the effects of aqueous leaf infusion of Pterocarpus santalinoides DC on serum lipid profile (SLP) of guinea pigs (GPs). METHODS: Fresh leaves of Pterocarpus. santalinoides were collected in February 2015. Aqueous leaf infusion was freshly prepared daily by soaking dried ground P. santalinoides leaf in hot water for 10 minutes. Twenty female GPs were randomly assigned into 4 groups (A  D) of 5 GPs each as follows: Group A  distilled water placebo per os (control), groups B, C and D  1.5, 3.0 and 4.5 g/kg body weight (bw) of ground P. santalinoides leaf in 600ml of hot and cooled water per os respectively. Treatment was carried out for 28 days. Assay of SLP was done on days 0 (before treatment), and on days 14 and 28 of treatment following standard procedures. RESULTS: The mean serum high density lipoprotein cholesterol (HDLC) of groups B, C and D rose to almost double its baseline values and was significantly (p < 0.05) higher than that of group A on day 28, while the mean serum low density lipoprotein cholesterol (LDLC) of group D was significantly lower (p
The effect of family supportive supervisor behaviors and work-family culture on turnover intention and work-family conflict

The purpose of this research was to look into the work-life interface of professionals in a de-manding and high-risk occupation in an organization in the security sector. Specifically, it focuses on the interaction between supervisor behaviors and culture with turnover intention and work-family conflict. The present study centers on data from a public security organization (3861) in a Latin American country. The validity of the measuring instruments was evaluated through Confirmatory Factor Analysis (CFA). Structural Equation Modeling (SEM) was then applied to evaluate the relationship between variables. Results found show a statistically significant negative impact of the supervisor behaviors in organizational (turnover intention) and individual outcomes (work-family conflict). At the same time, organizational culture negatively affects turnover intentions and work-family conflict. While confirming results coming from the private sector in other countries, the importance of supervisor behaviors and culture provides implications for work and family practices in this type of organization.
Factors Associated with Burnout in Clinical Year Medical Students in Terengganu, Malaysia

Abstract Many studies have shown that burnout had a detrimental effect on the well-being of medical students. In medical students, the prevalence of burnout increased as the year progressed. The Objective of the study was to determine the predictors for burnout in clinical year medical students. There were 120 clinical year medical students selected for this study using stratified random sampling. Students’ demographics, academic data, Copenhagen Burnout Inventory (CBI) and USM emotional intelligence Inventory (USMEQ-i) in Google Forms were distributed using WhatsApp application. Data include entry CGPA and whether they made the correct decision to do medicine and ever thought of dropping out. The response was in the form of ‘Yes/No’. Burnout was categorised into significant and non-significant burnout based on the mean CBI score. Each factor was categorized into two categories was analysed using Chi-Square test. Further analysis was done using multiple logistic regression. There were 105 students responded. The percentage of students categorised as having significant burnout was 41.0% (95% CI 31.5; 50.1). Incorrect decision to do medicine, ever thought of dropping out and lower emotional intelligence were significant predictors for burnout with odd ratio of 6.06, 3.06 and 3.24 respectively. As a conclusion, correct decision to do medicine and emotional intelligence were important predictors for burnout in clinical year medical students. They may be considered as important factors to be looked into during student selection interview. Keywords: Burnout, medical students, emotional intelligence
Effect of Species on Nutritive Value and Methane Production of Citrus Pulps for Ruminants

The experiment was carried out to determine the effect of species on the nutritive value and methane production of citrus pulps. Species had a significant effects (P<0.001) on the chemical composition, gas production, methane production, metabolisable energy (ME) and organic matter digestibility (OMD) of citrus pulps. Crude protein (CP) content of Citrus paradise was significantly (P<0.001) higher than those of the other citrus species. Neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents of Citrus sinensis and Citrus reticulata were significantly (P<0.001) lower than the others. Methane production from Citrus reticulata was significantly (P<0.001) higher than those of Citrus limon and Citrus paradise . The ME of pulp from Citrus reticulata was significantly (P<0.001) higher than that of Citrus limon pulp whereas OMD of pulp from Citrus reticulata was significantly (P<0.001) higher than those of pulps from Citrus limon and Citrus paradise . As conclusion, citrus pulps from different species have a high potential as forage for ruminant animals since citrus pulps have high ME and OMD. However, the CP contents of citrus pulps should be taken into consideration and diets should be fortified with additional CP sources to compensate for the low crude protein when citrus pulps are included into ruminant diets.

Our contribution is two-sided: we provide a theoretical framework to characterize interactive sound installations as well as a tool to inform sound artists and designers about up-to-date practices regarding interactive sound installations design.
A Study on the Distribution and Level of Cadmium in Scallop Bractechlamys vexillum (Reeve 1853) from the Visayan Sea, Philippines

Bivalves such as scallop Bractechlamys vexillum are considered an essential resource for livelihood and revenues in the Visayan Sea, central Philippines. To date, there are several reports that the local marine ecosystems are contaminated with heavy metals like cadmium; hence, these species are also susceptible to bioaccumulation of cadmium because they feed mainly by filtering particles from contaminated water. In recent studies, scallops are suggested to be a potential bioindicator for cadmium contamination due to their ability to accumulate and tolerate the metal. This research aims to examine the anatomical distribution of cadmium in B. vexillum and measure the relationship between shell weight and cadmium concentration. The sites for this study include Carles, Iloilo, Madridejos, Cebu, and Cawayan, Masbate. Five organs were analyzed: adductor muscle, digestive gland, gonad, gill, and mantle. The analysis for quantification of cadmium in the different scallop parts was carried out by Inductively Coupled Plasma – Optical Emission Spectrometry (ICP-OES Model ICPE-9820, Shimadzu, Kyoto, Japan). Results showed that cadmium preferentially accumulates in the digestive gland, accounting for 76.39% of the total metal concentration. Moreover, a significant positive correlation (r = 0.798, p < 0.01) between the cadmium content in the whole digestive gland and shell weight were observed. Thus, this tissue tends to have a potential marker of metal contamination in the environment.
Microbial Quality and Residues of Some Antibiotics in Conventional and Organic Table Eggs at Retail Stores in Kafrelsheikh Governorate

Chicken eggs are important as food to humans. The present study was conducted in Kafrelsheikh governorate, Egypt. A total of 250 samples (each sample contains 3 eggs) were purchased from different retail stores (conventional and organic, 125samples for each). These samples were subjected to microbiological examination for assessment of the sanitary quality and detection of incidence, serological and molecular characterization of salmonella, and subjected to chemical examination to detect the incidence of 2 antibiotic residues (oxytetracycline and tylosin) in both types of egg. Aerobic plate count showed mean values of 8.0×102 ± 4.6×10 cfu/ml for conventional eggs and 6.2×102 ± 3.2×10 cfu/ml for organic eggs, the coliform count showed a mean value of 4.6×102 ± 3.2×10 cfu /ml and 3.7×102 ± 2.6 ×10 cfu/ml for conventional and organic eggs respectively. Staphylococcus aureus count showed a mean value of 3.1×102±3.1 ×10 cfu/ml for conventional eggs and 2.3×102 ± 2.7 ×10 cfu/ml for organic egg. Mold and yeast count showed a mean value of 7.3×10 ± 3.8×10 cfu/ml and 4.2×10 ± 1.8 ×10 cfu/ml for conventional and organic eggs respectively. Salmonella was detected in 4 samples (1.6 % from total samples). All of them were only isolated from conventional eggs with a percentage of 3.2%. Serotype identification of four isolates was S. Kentucky. Salmonella Species were not isolated from organic egg contents. Multiplex PCR detected 3 virulence genes (hila, spvC, and stn) (100% of Salmonella isolates). No positive samples for microbial inhibitor test and no antibiotic residues in organic eggs and 4 conventional egg samples were detected positive for microbial inhibitor test with bacillus subtilis, which confirmed by HPLC for detection of 2 antibiotic residues (oxytetracycline and tylosin) and results revealed that 2 out of 4 positive inhibitor test samples were positive for oxytetracycline residues (317 µg /gm and 382 µg /gm) respectively, and 3 out of the same 4 samples were positive for tylosin residues (8.6 µg /gm, 48 µg /gm, and 18.5 µg /gm) respectively, and all positive samples exceeded the maximal residues limit (MRL 0.2 µg /gm) for both oxytetracycline and tylosin residues. The rate of detection of oxytetracycline and tylosin residues was (1.60%) and (2.4%) respectively from the conventional egg. Public health and economic importance for the isolated microorganisms and antibiotic residues were investigated. Results revealed that organic egg is safer than the conventional one.
Degree of coronary occlusions links to the patient clinical outcome: four cases of double culprits acute ST-segment elevation myocardial infarction

Background: Double coronary culprit lesions in ST-segment elevation myocardial infarction (STEMI) is uncommon. Despite successful primary percutaneous coronary intervention (PPCI) in all culprit lesions, the clinical outcome remains unfavorable and the possible factors for the outcome are not fully understood.Cases Presentation: We reported four cases of double culprit lesions STEMI underwent PPCI. Patient A, a 62 y.o. male with extensive anterior-inferior STEMI, had total occlusion (TO) at both proximal left anterior descending (LAD) and mid right coronary artery (RCA). Patient B, a 42 y.o. male with extensive anterior-inferior STEMI, had subtotal occlusion (STO) at proximal RCA and TO at proximal LAD. Both of them had RBBB ECG pattern. Patient C, a 67 y.o. male with inferior STEMI had 90% thrombus occlusion at proximal–mid LAD and TO at proximal RCA. Patient D, a 65 y.o. male with anteroseptal STEMI, had STO at proximal LAD and 80% thrombus occlusion at mid left circumflex. The cardiomyocyte infarction biomarkers increased in all patients. Although all of them underwent successful PPCI in all of culprit lesions, they suffered from acute heart failure and two of them experienced recurrent ventricular arrhythmia episodes. One of them (patient A) died two days post PPCI. He was only patient who suffering from total occlusion in LAD and RCA with TIMI thrombus 5 and experienced a total atrioventricular block post-PPCI.Conclusion: STEMI with coronary double culprits have severe clinical outcome, regardless of the successful PCI. The degree of coronary occlusions might be linked to the patient clinical outcome.
Simulating angular momentum of gravitational field of a rotating black hole and spin momentum of gravitational waves

In this research, we simulated the angular momentum of gravitational field of a rotating black hole and the spin momentum of gravitational waves emitted from the black hole. At first, we calculated energy densities of the rotating gravitational field and spinning gravitational waves as the vectors, which were projected on the spherical curved surface of the gravitational field and of the gravitational waves. Then we calculated the angular momentum and the spin momentum as the vectors perpendicular to the curved surface. The earlier research by Paul Dirac, published in 1964, did not select the curved surface to calculate the motion of quantum particles; but, instead, he chose the flat surface to develop the theory of quantum mechanics. However, we pursued the simulation of the gravitational waves in spherical polar coordinates that form the spherical curved surface of the gravitational waves. As a result, we found that a set of anti-symmetric vectors described the vectors that were perpendicular to the spherical curved surface, and with these vectors we simulated the angular momentum of the rotating black hole’s gravitational field and the spin momentum of gravitational waves. The obtained results describe the characteristics of the rotation of a black hole and of spinning gravitational waves.
