Speaking Risk With Our Project Managers
Authors: Nix Dustin , Fellows John , Hall John 
Published: May 2022

Effective communication between the system safety engineer and the project manager (PM) is an essential characteristic of good risk management in a robust system safety program. However, these two disciplines often use similar terms with disparate meanings that can lead to sub-optimal technical or programmatic outcomes. MIL-STD-882E defines “risk” as “a combination of the severity of the mishap and the probability that the mishap will occur”. The Project Management Book of Knowledge (PMBOK) Guide, 6th Edition, defines “individual project risk” as “an uncertain event or condition that, if it occurs, has a positive or negative effect on one or more project objectives”.
It is incumbent upon the system safety professional to clearly communicate safety-related issues, hazards, risks and concerns using language most likely to be understood by the PM to ensure that he or she has the requisite information to make a sound programmatic decision. This paper explores the discrepancies between project risk management and safety risk management standard processes that hinder clear communication and can drastically impact program performance. We present methods to consider that will improve understanding between the system safety professional and the PM, along with two framework approaches for integrating safety and project risks.

Published: May 2022

This study analyzes the differences in psychosocial variables as a function of the interpersonal teaching style in Secondary Education students. This descriptive cross-sectional study was carried out with a sample consisted of 120 students, aged 12 to 17 years (M = 13.4, SD = 1.36). A battery of validated questionnaires was completed to analyze motivation, basic psychological needs, school social climate, sports satisfaction and the teaching interpersonal style, which acted as a variable to elaborate the cluster profiles. The analysis of the dendrogram suggested the creation of two profiles, the first, “high autonomy support” and the second, “high controlling style”. The multivariate analysis showed higher values ​​for the first profile in autonomy, competence, social relationship, teacher climate and fun, while the second profile being higher in amotivation and boredom. It is concluded that greater support for autonomy allowed greater satisfaction of the adaptive psychological variables.

A field test of forest canopy structure measurements with the CanopyCapture smartphone application
Authors: Lusk Christopher H. 
Published: May 2022

Background
Several smartphone applications have been developed for the purpose of low-cost and convenient assessments of vegetation canopy structure and understorey illumination. Like standard hemispherical photography, most of these applications require user decisions about image processing, posing challenges for repeatability of measurements. Here I report a test of CanopyCapture, an application that instantaneously estimates percentage canopy gap fraction without any input from the user, and has the added advantage of an intuitive levelling mechanism.

Methods
Gap fraction estimates by CanopyCapture were compared with gap fraction values computed by the LAI-2200C Canopy Analyzer, in two contrasting evergreen temperate forests in New Zealand: an even-aged southern beech (Nothofagus) stand and an old-growth podocarp/broadleaf forest. These comparisons were repeated using a wide-angle adapter to enhance the smartphone camera’s field of view from 45 to 65°. I also asked if CanopyCapture results depended on sky condition (sunny vs. overcast) and on the type of smartphone used.

Results
CanopyCapture output was significantly correlated with gap fraction computed by the LAI-2200C (R2 = 0.39), and use of the wide-angle adapter lifted this value to 0.56. However, CanopyCapture output was not significantly correlated with LAI-2200C output in the even-aged Nothofagus stand, where there was less spatial variation in canopy structure. Despite being much less sensitive to variation in gap fraction than the LAI-2200C, CanopyCapture was nevertheless able to detect differences in average gap fraction between the two forests studied. CanopyCapture results beneath intact canopies were not significantly affected by sky condition, but reflection of direct light off tree trunks in sunny weather caused slight overestimation of gap fraction beneath broken canopies and gaps. Uneven or patchy cloud cover can also cause erroneous readings beneath large canopy openings. Three different models of smartphone gave different results.

Conclusions
CanopyCapture offers a rapid and repeatable proxy for comparisons of average canopy gap fraction in multiple stands/forests, provided large sample sizes are used. Measurement under even overcast skies is recommended, and studies involving multiple operators will need to standardize smartphones to ensure comparability of results. Although wide-angle adapters can improve performance, CanopyCapture’s low sensitivity prevents high-resolution comparisons of the light environments of individual understorey plants within a stand.

Background: In Cameroon, numerous people rely on medicinal plants and possess knowledge on the use of these plants. Plant knowledge from indigenous people is rapidly disappearing due to environmental, social and economic pressure, processes and changes. In view of this, ethnobotanical studies have been carried out in the area where medicinal plants are the main source of health care in order to preserve traditional knowledge of plant use. This study aims to document and quantify medicinal plant knowledge on the treatment of diabetes, hypertension and cardiovascular ailments in Fokoue and Santchou subdivisions of Menoua Division, West Cameroon.
Methods: Information related to medicinal plant species and plant remedies was collected through semi-structured interviews with 34 informants accompanied by homegarden sampling, walk-in-the-woods and snowball sampling. Quantitative methods were used to determine cultural importance index, relative frequency of citation and fidelity level which represent informants’ consensus.
Results: A total of 49 medicinal plant species representing 26 different botanical families were recorded in Fokoue and Santchou subdivisions of Menoua Division, West Cameroon. Most-cited plant families were Acanthaceae, Amaryllidaceae, Apocynaceae, Asteraceae, Lamiaceae, Poaceae and Rhamnaceae. Plant species Allium sativum, Aloe vera, Asystasia spp., Cymbopogon citratus, Gouania spp., Persea americana, Sonchus oleraceus and Vernonia amygdalina were considered as relatively important plants for treating diabetes, hypertension and cardiovascular ailments.
Conclusions: The study indicated the unique knowledge of medicinal plants used for treating diabetes, hypertension and cardiovascular ailments in Fokoue and Santchou subdivisions. Our findings not only confirm uses of medicinal plants documented elsewhere, but also add interesting new information that should be confirmed through formal biochemical analysis and clinical trials.

AbstractGraphene nanoribbons (GNRs) with widths of a few nanometers are promising candidates for future nanoelectronic applications due to their structurally tunable bandgaps, ultrahigh carrier mobilities, and exceptional stability. However, the direct growth of micrometer‐long GNRs on insulating substrates, which is essential for the fabrication of nanoelectronic devices, remains an immense challenge. Here, the epitaxial growth of GNRs on an insulating hexagonal boron nitride (h‐BN) substrate through nanoparticle‐catalyzed chemical vapor deposition is reported. Ultranarrow GNRs with lengths of up to 10 µm are synthesized. Remarkably, the as‐grown GNRs are crystallographically aligned with the h‐BN substrate, forming 1D moiré superlattices. Scanning tunneling microscopy reveals an average width of 2 nm and a typical bandgap of ≈1 eV for similar GNRs grown on conducting graphite substrates. Fully atomistic computational simulations support the experimental results and reveal a competition between the formation of GNRs and carbon nanotubes during the nucleation stage, and van der Waals sliding of the GNRs on the h‐BN substrate throughout the growth stage. This study provides a scalable, single‐step method for growing micrometer‐long narrow GNRs on insulating substrates, thus opening a route to explore the performance of high‐quality GNR devices and the fundamental physics of 1D moiré superlattices.

Published: May 2022

AbstractThe multiple issues of unstable electrode/electrolyte interphases, sluggish reaction kinetics, and transition‐metal (TM) dissolution have long greatly affected the rate and cycling performance of cathode materials for Na‐ion batteries. Herein, a multifunctional protein‐based binder, sericin protein/poly(acrylic acid) (SP/PAA), is developed, which shows intriguing physiochemical properties to address these issues. The highly hydrophilic nature and strong H‐bond interaction between crosslinking SP and PAA leads to a uniform coating of the binder layer, which serves as an artificial interphase on the high‐voltage Na4Mn2Fe(PO4)2P2O7 cathode material (NMFPP). Through systematic experiments and theoretical calculations, it is shown that the SP/PAA binder is electrochemically stable at high voltages and possesses increased ionic conductivity due to the interaction between sericin and electrolyte anion ClO4−, which can provide additional sodium‐migration paths with greatly reduced energy barriers. Besides, the strong interaction force between the binder and the NMFPP can effectively protect the cathode from electrolyte corrosion, suppress Mn‐dissolution, stabilize crystal structure, and ensure electrode integrity during cycling. Benefiting from these merits, the SP/PAA‐based NMFPP electrode displays enhanced rate and cycling performance. Of note, the universality of the SP/PAA binder is further confirmed on Na3V2(PO4)2F3. It is believed that the versatile protein‐based binder is enlightening for the development of high‐performance batteries.
Aerodynamic and Acoustic Simulations of Thick Flatback Airfoils Employing High Order DES Methods
Authors: Bangga Galih , Seel Ferdinand , Lutz Thorsten , Kühn Timo 
Published: May 2022

AbstractThe results of high fidelity aerodynamic and acoustic computations of thick flatback airfoils are reported in the present paper. The studies are conducted on a flatback airfoil having a relative thickness of 30% with the blunt trailing edge thickness of 10% relative to chord. Delayed Detached‐Eddy Simulation (DDES) approaches in combination with high order (5th) flux discretization WENO (Weighted Essentially Non‐Oscillatory) and Riemann solver are employed. Two variants of the DES length scale calculation methods are compared. The results are validated against experimental data with good accuracy. The studies provide guideline on the mesh and turbulence modeling selection for flatback airfoil simulations. The results indicate that the wake breakdown is strongly influenced by the spanwise resolution of the mesh, which directly contributes to the prediction accuracy especially for drag force and noise emission. The Reynolds normal stress and the Reynolds stress component have the largest contributions on the mixing process, while the contribution of the component is minimal. Proper orthogonal decomposition is further performed to gain deeper insights into the wake characteristics.

AbstractBiodiesel has recently gained popularity due to its environmental issues and the fact that it is generated from renewable resources. However, the cost of the synthesis of biodiesel is the major impediment to commercialization. The utilization of leftover cooking oils as raw material, the adaptation of a continuous transesterification process, and the use of cheap catalysts are the major possibilities for investigating the cost of biodiesel. In this work, a dolomite catalyst was prepared from natural dolomite rocks and used for the evaluation of continuous transesterification of biodiesel from oleic acid as a model compound of waste cooking oil (WCO). The dolomite catalyst was prepared by activation under vacuum at a surface area of 34.5 m2/g. The characterization tests showed good thermal stability of the catalyst and evolution of the CaO and MgO compounds at high concentrations. A kinetic study was conducted to obtain kinetic parameters of catalytic transesterification of the WCO. The kinetic experiments were carried out at 298–333 K, and residence time up to 80 min. The results presented that the catalytic transesterification is the first‐order reaction, and the activation energy was 43 kJ/mol. The oscillatory baffled reactor (OBR) was used to evaluate the dolomite catalyst for the continuous production of biodiesel via transesterification. The evaluation study was conducted at a methanol: oil mole ratio of 6:1 and the effect of different operation variables on oleic acid conversion to biodiesel was studied. These variables were temperature (323, 333, and 343 K), residence times (5–40 min), the amplitude of oscillation (2–8 mm), and frequency of oscillation (1, 2, 3, 4, and 4.3 Hz). The results showed an outstanding performance and stable activity of the dolomite catalyst as a conversion of 96% was obtained at 333 K, 4.3 Hz, 8 mm amplitude, and 40 min residence time.

AbstractTherapy‐related myeloid neoplasms (t‐MN) are aggressive malignancies in need of effective therapies. The BCL‐2 inhibitor venetoclax represents a paradigm shift in the treatment of acute myeloid leukemia. However, the effectiveness of venetoclax has not been studied in a large cohort of t‐MN. We retrospectively analyzed 378 t‐MN patients, of which 96 (25.4%, 47 therapy‐related acute myeloid leukemia, 1 therapy‐related chronic myelomonocytic leukemia, 48 therapy‐related myelodysplastic syndrome) received venetoclax. Median interval from t‐MN to venetoclax initiation was 2.9 (Interquartile range [IQR] 0.7–12) months, and patients received a median of 3 (IQR 1–4) cycles. The composite complete remission (CRc) rate, median progression‐free survival (PFS), and overall survival (OS) were 39.1%, 4.9 months, and 7 months, respectively. The upfront use of venetoclax and achieving CRc were associated with improved survival, whereas the presence of Chromosome 7 abnormalities was associated with an inferior survival. Neither the TP53‐status nor the percent bone marrow blast predicted the likelihood of CRc or survival. Paired genetic analysis performed at venetoclax initiation and failure did not show the evidence of the selection of the TP53‐mutated clone. In a propensity‐matched analysis, the use of venetoclax‐based regimen as the first‐line therapy was associated with a superior survival compared to hypomethylating agent (HMA)‐based first‐line therapy (9.4 vs. 6.1 months, p = .01). We conclude that the upfront use of venetoclax with HMA improved survival, though PFS and OS remain poor. As the phenotype at diagnosis or the percent blasts did not predict outcomes, venetoclax should be studied in all t‐MN phenotypes.

AbstractInspired by our previous work, we herein demonstrate a one‐pot method to obtain thiophenes by directly recurring to the thiolation and deoxygenation of Lawesson's reagent and using succinic anhydrides as substrates, where 35 examples are displayed. The synthesis has several desirable features, such as a one‐pot protocol, easily available materials, excellent functional group tolerance, and absence of metal. The synthetic strategy provides a concise and efficient method for the construction of diverse thiophenes.

AbstractPhotocatalytic conversion of CO2 into transportable fuels such as formic acid (HCOOH) under sunlight is an attractive solution to the shortage of energy and carbon resources as well as to the increase in Earth's atmospheric CO2 concentration. The use of abundant elements as the components of a photocatalytic CO2 reduction system is important, and a solid catalyst that is active, recyclable, nontoxic, and inexpensive is strongly demanded. Here, we show that a widespread soil mineral, alpha‐iron(III) oxyhydroxide (α‐FeOOH; goethite), loaded onto an Al2O3 support, functions as a recyclable catalyst for a photocatalytic CO2 reduction system under visible light (λ>400 nm) in the presence of a RuII photosensitizer and an electron donor. This system gave HCOOH as the main product with 80–90 % selectivity and an apparent quantum yield of 4.3 % at 460 nm, as confirmed by isotope tracer experiments with 13CO2. The present work shows that the use of a proper support material is another method of catalyst activation toward the selective reduction of CO2.
Preparation and characterization of poly(lactic acid)/boron oxide nanocomposites: Thermal, mechanical, crystallization, and flammability properties
Authors: Kangallı Emine , Bayraktar Emine 
Published: May 2022

AbstractIn this study, poly(lactic acid)/boron oxide nanocomposites (PLA/BONPs) were prepared by solution casting method and characterized by thermogravimetric analysis, differential scanning calorimetry analysis, limiting oxygen index (LOI) and mechanical test. The particle size of boron oxide was reduced to nanosize using SPEX ball mill and boron oxide nanoparticles (BONPs) were functionalized with oleic acid, [3‐(trimethoxylsilyl) propylmethacrylate] and triethoxyvinylsilane (VS). Obtaining of nanosized and surface functionalized BONPs enhanced the crystallinity, mechanical, and flammability properties of PLA/BONPs. Compared with the neat PLA, crystallinity increased from 13.68% to 32.55% for 5 wt% VS functionalized BONPs added nanocomposite, tensile strength increased from 41.25 ± 0.80 MPa to 51.12 ± 2.54 MPa for 2.5 wt% VS functionalized BONPs added nanocomposite and LOI increased from 21.2 to 26.8 for 5 wt% VS functionalized BONPs added nanocomposite. Functionalized BONPs increased the thermal degradation temperature of nanocomposite slightly. With the enhanced mechanical and flammability properties PLA/BONPs nanocomposites are good candidate for packaging, electronic, and automotives industries.
