Accuracy of Healthcare Providers' Perception of Chest Compression Depth and Chest Recoil

Objective: The objective of this paper was to evaluate the validity and accuracy of healthcare providers’ perception of chest compression depth and chest recoil during cardiopulmonary resuscitation (CPR). Methods: A clinical simulation study was performed with healthcare providers trained in CPR including physicians, nurses, and Emergency Medical Technicians (EMT). Following 2 minutes of hands-only-CPR on a sensor-programmed manikin, providers were able to respond to subjective questions assessing their adequacy of CPR. The providers’ perception contrasted with the objective data obtained from the manikin. The validity and accuracy of CPR providers’ perception of chest compression depth and chest recoil was assessed by the calculation of sensitivity, specificity and predictive values. Results: 180 Advanced or basic life support certified healthcare providers were enrolled. The degree of correlation between self-perception and actual performance was 52.2% in the thoracic compression depth and 61.7% in the chest recoil. Caregivers’ perception of chest compression depth had a sensitivity of 29.4% and a specificity of 87.3%. Caregivers’ perception of chest recoil had a sensitivity of 30.3% and a specificity of 79.8%. Conclusions: Healthcare providers’ perception for evaluating the accuracy of thoracic compressions is not as accurate as objective feedback methods during CPR. This may impact patient outcomes during a cardiac arrest.
Teaching English in Multilingual Contexts: Teachers' Perspectives

The national and international migration has made multilingualism a common phenomenon; Nepal is no exception. Nepal is regarded as a multilingual country where more than 129 languages are spoken. Despite multilingualism, English language has been taught from basic to advance levels of education as a core or optional subject. In this context, this article has investigated challenges faced by English teachers in teaching English in multilingual classes of Nepal. The article has also attempted to explore the strategies employed by teachers to deal with the challenges that they faced. To achieve these objectives, explanatory sequential mixed research design was used. Eighty basic level English language teachers from forty different (2 from each) schools of Kaski district were selected purposively. The data was collected through survey questionnaires, interview and classroom observation. The research showed that linguistic diversity, students classroom behavior and demotivation towards English, uncontextual and lengthy syllabus, lack of teachers' involvement in curriculum designing process and refresher courses programmes were the major challenges that the teachers have faced while teaching English. The research also indicated that the use of translation, use of increasing reading materials, managing rewards to the students, and repetition of the text were the major strategies that teachers employed to cope with the challenges in multilingual contexts. This implies that the policy makers, curriculum designers, and administrators should train the teachers to address these issues that are related to teaching English in a multilingual context like in Nepal.
Clinical presentation, hormonal profiles in nulliparous Korean women with polycystic ovarian morphology

Purpose: The aim of this study was to determine the relationship between polycystic ovarian morphology (PCOM), ovarian morphology, anti-Müllerian hormone (AMH), and testosterone levels in young nulliparous Korean women. Materials and Methods: A total of 139 PCOM patients were evaluated from 2013 to 2018. The relationships between serum AMH levels and androgenic hormones, clinical signs of polycystic ovarian syndrome (PCOS), and ovarian morphology were investigated. Results: Irregular menstruation was the most common symptom in women with PCOM. This study found that hyperandrogenism was present in 26.6% of nulliparous Korean women with PCOM. The present findings support the use of serum AMH as a useful marker to reflect PCOM in cases where accurate ultrasounds are not available. Conclusions: This study found that PCOM did not equate with PCOS, although PCOM is one of the diagnostic criteria for PCOS. AMH levels were positively correlated with ovarian volume and AMH levels were not reflected by hyperandrogenism. Content: The use of serum AMH as a useful marker to reflect PCOM in cases where accurate ultrasounds are not available.
Bee diversity responses to forest and open areas in heterogeneous Atlantic Forest

Agriculture driven landscape changes has caused worldwide forest loss and fragmentation, seriously affecting biodiversity and ecosystem services, amongst which pollination is remarkably important. Bees are an essential pollinator group for forest plant populations and food production in tropical landscapes. They are also dependent on forested environments which are essential to maintain their diversity and pollination services. We analyzed bee diversity in contrasting forest and adjacent non-forest patches to evaluate if bees can use complementary non-native environments in heterogeneous altered tropical landscapes. The effect of landscape level heterogeneity and forest amount on bee diversity was also assessed. Our hypothesis was that bee communities would be more rich and diverse inside the forest understory, but due to supplementary foraging behaviors they would be more abundant in non-forested areas where flower availability is higher. We actively sampled bees visiting flowers within forest patches and in surrounding non-forest open areas between the Cantareira and Mantiqueira mountain ranges in São Paulo, Brazil. We found higher bee richness and diversity in open areas than in forest patches, partially denying our initial hypothesis but supporting that bees are more abundant in non-forest areas. We found strong indication that landscapes with higher amount of forest and environmental heterogeneity can provide more resources for bees through resource complementation processes, maintaining their diversity in the landscape. The presence of forest patches close to crop and open areas is of utmost importance for the conservation of bees and pollination services with important consequences for land management in tropical environments.
A Novel Protein-Protein Interaction Assay Based on the Functional Complementation of Mutant Firefly Luciferases: Split Structure Versus Divided Reaction

Protein-fragment complementation assays (PCAs) are commonly used to assay protein–pro- tein interaction (PPI). While PCAs based on firefly luciferase (Fluc) in cells or lysates are a user-friendly method giving a high signal/background (S/B) ratio, they are difficult to use in vitro owing to the instability of split Fluc fragments. As a solution to this issue, we devel oped a novel protein–protein interaction assay named FlimPIA using two mutant Flucs, each of which catalyzes one of the two half-reactions catalyzed by the wild-type enzyme. Upon approximation by the tethered protein pairs, the two mutants yielded higher signal owing to a more efficient transfer of the reaction intermediate luciferyl adenylate. FlimPIA showed many advantages over in vitro split Fluc assays, such as longer detectable distance, more sta - ble probes, and higher signal readout in a shorter time period, and it also worked in cellulo.
PlantAI: Aplicativo de classificação e localização de plantas em risco de extinção na Mata Atlântica

Identification of species of plants in extinction is an important but complex task. The Lista Vermelha project exists to catalog list of plants classified into different threat levels, and has a team composed of professionals responsible for assessing the risk of extinction of species of brazilian flora. However, due to the diversity and similarity contained in Brazilian biomes, the correct identification of plants is not a trivial task. Technological advances have contributed to this goal, making it possible to obtain a large amount of data from different sources, which motivated this work to present a prototype smartphone application instructed to classify plants with different threat levels of the Mata Atlântica, and map them collaboratively. A Convolutional Neural Network was trained with augmented samples of different plant species, using the transfer learning technique in different convolution blocks of the MobileNet model, and is used for online classification of image collected with the application. The experiments were conducted in the city of Jacareı́-SP. For the two species evaluated, Araucaria and Pitanga, it was obtained an accuracy of more than 90%. Resumo. A identificação de espécies de plantas em extinção é uma tarefa importante, porém complexa. O projeto Lista Vermelha existe para catalogar a lista de plantas classificadas em diferentes nı́veis de ameaça e conta com uma equipe composta por profissionais responsáveis em avaliar o risco de extinção de espécies da flora brasileira. Ainda assim, devido à diversidade e à similaridade contida nos biomas brasileiros, a identificação correta de plantas não é uma tarefa trivial. Os avanços tecnológicos vieram contribuir neste sentido, tornando possı́vel a obtenção de um grande volume de dados de diferentes fontes, o que motivou este trabalho a apresentar um aplicativo protótipo instruı́do para classificar plantas com diferentes nı́veis de ameaça da Mata Atlântica, e mapeá-las de forma colaborativa.

Os experimentos foram realizados no municı́pio de Jacareı́-SP. Para as duas espécies avaliadas, Araucária e Pitanga, obteve-se a acurácia superior a 90%.
Aronia melanocarpa ameliorates gout and hyperuricemia in animal models

ABSTRACT Aronia melanocarpa fruit (AM) strongly suppressed ankle swelling in rats with acute gout and reduced the levels of uric acid and xanthine oxidase (XO) in mice with hyperuricemia. AM reduced the inflammatory cell count and increased the ankle joint space, and suppressed the levels of interleukin (IL)-1β, IL-10, monocyte chemoattractant protein-1 and tumour necrosis factor-α in the serum of the rats with acute gout. In the mice with hyperuricemia, AM significantly reduced the serum levels of uric acid, blood urea nitrogen, and creatinine. 8-day administration of AM resulted in enhancements in the levels of glutathione peroxidase, superoxide dismutase and catalase and a reduction in the level of malondialdehyde in the serum of mice. All data suggested that the potential therapeutic effects of AM on gout are probably due to the regulation of pro- and anti-inflammatory cytokines and the suppression of XO activity via modulation of the oxidative stress status.
Competition assessment in business negotiations under distorting market conditions

The competition assessment process provides an analytical framework for business negotiation entities to mitigate, or avoid potential competition problems. It helps to identify possible alternatives that may reduce, or eliminate potential harm to competition. Limiting the number of business negotiation enti-ties leads to the risk that market power will be created and competitive rivalry will be reduced. The aim of the article is to analyze the theory and practice of developing and implementing business negotiation strat-egies in a complex way, also to evaluate the level of competition in distorting market conditions. The ob-ject of the study is to strike a balance at the level of competition in business negotiations, under distorting market conditions. The scientific problem is that bargaining theory lacks tools to assess and balance the level of competition between participants in market conditions that distort competition.

Graphene from waste and bioprecursors synthesis method and its application: A review

Recently, carbonaceous material such as porous carbon, carbon nanotubes (CNTs), graphene, graphene oxide (GO) and activated carbon has received tremendous attention from researchers. To date, the exploration of graphene is still in vast. Graphene has been applied in various applications which include polymer composites, energy storage, fuel cell and biomedical applications. This is due to its unique characteristics such as large surface area and high remarkable electronic, mechanical and thermal properties. Even though chemical vapor deposition (CVD) has been established as an effective method to synthesize graphene, but the yield is low and may not compatible in certain applications. In addition, the chemical process of the production of graphene from exfoliation of graphite oxide involves hazardous and toxic reagents. Currently, bio-waste materials have been a great source for production of carbon. Furthermore, bio-waste materials are abundant and proper disposal method is needed. Hence, preparation of graphene from waste and biomass precursors is a new alternative to overcome the afore mentioned problem. Therefore, this paper will be focused on the method of synthesizing graphene from glucose, rice husk, chitosan, corn stalk core and plastic waste. The application of graphene derived from each bioprecursor for dye removal, adsorption of toxic and heavy metals, gas storage and supercapacitors will also be reviewed.

Basically, there is a need to rethink with the educational procedures used and develop their education.
Drug-Induced Sleep Endoscopy: A Guide for Treatment Selection

Identifying the sites, severity, and pattern of upper airway obstruction in obstructive sleep apnea is crucial for determining the treatment options, particularly the surgical plan. Although early methods of assessment, such as Muller’s maneuver, computed tomography, and magnetic resonance imaging in awake patients have been utilized to assess obstructive sites, the physiologic and anatomical differences between awake and sleeping patients showed a limited ability of those methods as diagnostic tools. Recently, drug-induced sleep endoscopy (DISE) was introduced as a useful diagnostic and evaluation tool to identify dynamic upper airway collapse during sedation that simulates natural sleep. In this article, we review all aspects of DISE, including the technique, evaluation methods, and clinical application. Sleep Med Res 2020;11(1):1-6
Externalisierung von prozess-spezifischem Mitarbeiterwissen im Produktionsumfeld

Kurzfassung Mitarbeiter im direkten Produktionsumfeld sind durch die zunehmende Komplexität in der industriellen Produktion mit immer weiter steigenden Anforderungen an ihre Tätigkeiten konfrontiert. Das Wissen über individuelle Produktionsprozesse und spezifische Problem-lösungsstrategien liegt dabei oftmals nicht in expliziter Form, sondern hauptsächlich als implizites Erfahrungswissen vor. Zur Verfügbarmachung von produktionsbezogenem Wissen ist deshalb ein systematisches Vorgehen zur Wissensexternalisierung, -speicherung und -wiederverwendung erforderlich. Basierend auf einer Kombination und Adaption verschiedener Methoden aus den Bereichen des Wissensmanagements sowie der Sozialforschung stellt dieser Beitrag zuerst einen Ansatz zur Externalisierung von prozessspezifischem Mitarbeiterwissen vor. Anschließend findet eine Verprobung der entwickelten Methodik in einem kontinuierlichen Fertigungsszenario statt.
Population Dynamics and Seasonal Abundance of the Beetle Oryctes owariensis Beavois, 1807 (Coleoptera: Scarabaeidae: Dynastinae) in Raphia Palms in Bayelsa State, Nigeria

Oryctes owariensis (Coleoptera: Scarabaeidae) beetle is a destructive insect pest of both raphia and oil palms, causing damage to the fronds and trunk thus leading to low yields and subsequent death of infested palms. This study was aimed at monitoring the seasonal abundance of the beetle using visual lure or light traps suspended on poles around raphia palm farms designed as experimental sites (Locations A, B, C and D) for a duration of two years (2018 and 2019) in Bayelsa State. Four sampling seasons were engaged in the study: Four months of dry (JanuaryApril) and four months of wet (JuneSeptember) yearly. The lamps were powered seven consecutive nights monthly. Beetles trapped were counted daily and the numbers recorded. The result showed that the beetle had one generation per year, was nocturnal with seasonal activity spreading out from dusk to dawn. Adult population was highest within the dry sampling months of March to April as the insects mate for breeding, the wet months June and July recorded drastic fall Original Research Article Boate and Otayor; AJOB, 9(3): 14-27, 2020; Article no.AJOB. 57385 15 in the number of trapped beetles while August and September recorded no catch. A total of 283 beetles were captured during the dry season against 8 trapped at the wet. Therefore, the high efficiency of the light traps as capture/ monitor tools in ascertaining the seasonal abundance of Oryctes owariensis beetle in raphia palm farms is a possibility for use in Integrated Pest Management Programs for controlling the pest population before they reach the economic threshold level.
Effect of Acetonitrile on RDX Biodegradation in an Unsaturated Surface Soil

Abstract : In previous work, we documented the biodegradation of hexahydro-1,3,5- trinitro-1,3,5-triazine (RDX) in an unsaturated cold-region surface soil and showed that acetonitrile (ACN) could inhibit RDX removal rates when used as a dispersant for the contaminant. Here, we document that the added ACN had an effect on microbial community development in the RDX-contaminated soil. In the absence of ACN, the soils showed a striking increase in microbial biomass and in biomarkers indicative of microfauna. A four-fold increase in the phospholipid fatty acid (PLFA) biomarkers 18:2w6 and 20:4w6 (approximately 4-16 mol %) coincided with a greater than two-fold increase in total microbial biomass (approximately 15-35 nmol g(-1) PLFA). In the presence of ACN (1% aqueous concentration), these increases were not observed. The ACN-free soils also showed a significant decrease in PLFA biomarkers for Gram-negative bacteria (i.e., approximately 15 mol% decrease in w7 monounsaturated PLFA). This decrease was not observed in soils amended with 1% ACN. We concluded that the organic solvent interfered with microbial community development, specifically the trophic interaction between free-living protozoa and Gram-negative bacteria. Since the addition of 1% ACN increased the half-life for RDX from 29 to 48 days, the trophic interaction may be a necessary component in the development of an RDX-biodegrading microbial community.
Investigations on the Processing and Production of Herbal Tea from Pakalana Telosma cordata, Fowers using Blanching and Drying

Tea is one of the most popularly consumed beverages worldwide. Pakalana (Telosma cordata Merrill) or Thien Ly flower as a valuable crop in different rural areas of Vietnam. It has a great amount of phytochemical components beneficial for human health. It can be converted into herbal tea like a healthy drink. There is not any literature mentioned to tea processing from the Pakalana (Telosma cordata Merrill) flower. Therefore objective of this study focused on the effect of citric acid concentration (0.05, 0.1, 0.15, 0.2, 0.25%) in blanching; vacuum drying temperature (40oC, 45oC, 50oC, 55, 60oC) and pressure (-0.2, -0.4, -0.6, -0.8, -1.0 bar) to total phenolic content (mg GAE/g), antioxidant activity (μM Fe2+/g) and organoleptic attribute (sensory score) of the dried pakalana flower tea. Results showed that pakalana flower should be blanched in hot water 95oC at 5 seconds in the present of citric acid 0.2% and then being dried by vacuum dryer at 50oC, -0.8 bar for 6 hours to get the final moisture content below 10.0% available for preservation. Pakalana flower could be utilized as an appropriate material for processing one kind of functional food.
Exo-Inulinase Production by a Catabolite Repression-Resistant Mutant Thermophilic Aspergillus tamarii-U4 in Solid State Fermentation

In this study, spores of inulinase-producing thermophilic Aspergillus tamarii were subjected to UV mutagenesis, and colonies obtained were screened for inulinase production on inulin-glucose agar. The thermal stability of the inulinase was also investigated. A mutant strain U4 was found to produce 2.8 times inulinase titre (62.1U/mL) as against the wild strain (22.2U/mL). Inulinase production by this U4 strain was also found not to be significantly (P≤0.05) affected by the presence of glucose. The inulinase produced retained 64% of its activity after incubation at 65oC for three hours. Solid-state fermentation for inulinase production by the strain U4 showed that wheat bran supported the highest inulinase titre 218.3U/gds while banana peels supported the lowest inulinase production titre of 80.5U/gds. Further optimization of cultural parameters revealed that incubation time of 5 days, 60% initial moisture content of the substrate, 2% inoculum density 2%, temperature 55oC and pH 4.5 were optimal for inulinase production. Under optimized conditions, inulinase titre of 426.6 U/gds was observed. The pattern of inulin hydrolysis by the inulinase revealed the presence of monosaccharide as the main product of hydrolysis. Inulinase Original Research Article Garuba and Onilude; BJI, 24(4): 21-31, 2020; Article no.BJI. 57865 22 production at elevated temperatures by the mutant Aspergillus tamarii-U4 and its catabolite resistant properties showed that the organism is a potential industrial candidate for the production of exoacting inulinases.
