Abstract In a recultivation area located in Brandenburg, Germany, five types of biocrusts (initial BSC1, developed BSC2 and BSC3, mosses, lichens) and non-crusted mineral substrate were sampled on tertiary sand deposited in 1985- 1986 to investigate hydrologic interactions between crust patches. Crust biomass was lowest in the non-crusted substrate, increased to the initial BSC1 and peaked in the developed BSC2, BSC3, the lichens and the mosses. Water infiltration was highest on the substrate, and decreased to BSC2, BSC1 and BSC3. Non-metric multidimensional scaling revealed that the lichens and BSC3 were associated with water soluble nutrients and with pyrite weathering products, thus representing a high nutrient low hydraulic feedback mode. The mosses and BSC2 represented a low nutrient high hydraulic feedback mode. These feedback mechanisms were considered as synergic, consisting of run-off generating (low hydraulic) and run-on receiving (high hydraulic) BSC patches. Three scenarios for BSC succession were proposed. (1) Initial BSCs sealed the surface until they reached a successional stage (represented by BSC1) from which the development into either of the feedback modes was triggered, (2) initial heterogeneities of the mineral substrate controlled the development of the feedback mode, and (3) complex interactions between lichens and mosses occurred at later stages of system development.

The objective was to evaluate the effects of the probiotics Bacillus subtilis and Bacillus cereus (4x1011 CFU kg−1) (BSC) in diets for Nile tilapia fingerlings. A total of 450 fish (average weight of 2.81 ± 0.06 g) were distributed in a completely randomized design, in 15 aquariums of 210 liters, consisting of five treatments and three replications. The isoproteic and isoenergetic experimental rations were formulated as follows: BSC1: 0% (control); BSC2: 0.6%; BSC3: 0.8%; BSC4: 1.0%; BSC5: 2.0% of probiotics per kg of feed at a concentration of 4x1011 CFU kg−1. The animals were fed the experimental diets for 30 days. At the end of the study, the productive performance was determined, and bromatological and histological analyzes of the fish were carried out. It was concluded that the probiotic did not influence the zootechnical performance of Nile tilapia fingerlings. The use of 0.8% of BSC appeared as a dietary supplementation strategy for Nile tilapia fingerlings, due to the efficacies found in the main results of body centesimal composition and in adaptations in the histomorphometry of the intestinal villi.

Responsiveness/relevance is perceived as the starting point for determining what constitutes a quality education. Since development is necessary, systems that support development, like education and training systems, must be responsive. This study is focused on the relevance and responsiveness of the Bachelor of Science in Customs Administration (BSCA) program and to determine whether the initiatives currently practiced by the college to make the program relevant/responsive are effective. John B. Lacson Colleges Foundation-Bacolod is a higher education institution that offers a BSCA program and is the only one in Negros Occidental. However, despite the very satisfactory results in the board examination in the past years and the high demand for employment in the import and export industry, only a few are enrolled in the program. Hence, the conduct of this study is to explore opportunities to improve enrolment. This descriptive study used the survey method to gather the data needed, with Mean and Standard Deviation as statistical tools. A discussion with representative stakeholders was made on the initiatives and strategies practiced by the college to calibrate the program. The respondents were 24 BSCA students, 53 alumni, and 22 industry representatives. The findings showed that the BSCA program is relevant and responsive to a very great extent, as assessed by the alumni and students, and relevant/responsive to a great extent by the industry.

Abstract Objective. To monitor the human respiration rate (RR) using infrared thermography (IRT) and artificial intelligence, in a completely contactless, automated, and non-invasive manner. Approach. The human breathing signals (BS) were obtained using IRT, by plotting the change in temperature occurring across the nostrils during breathing, with respect to time. The RR was monitored under extreme conditions (random head motion, involuntary body movements, etc), by developing deep learning (DL) based ‘Residual network50+Facial landmark detection’ (ResNet 50+FLD) model. This model was built and evaluated on 10 000 thermograms and is the first work that documents the use of a DL classifier on a large thermal dataset for nostril tracking. Further, the acquired BS were filtered using the moving average filter (MAF), and the Butterworth filter (BF), and a comparative analysis of their performance was done. The novel ‘breathing signal characterization algorithm (BSCA)’ was proposed to obtain the RR in an automated manner. This algorithm is the first work that identifies the breaths in the thermal BS as regular, prolonged, or rapid, using machine learning (ML). The ‘exploratory data analysis’ was performed to choose an appropriate ML algorithm for the BSCA. The performance of the ‘BSCA’ was evaluated for both ‘decision tree (DT)’ and ‘support vector machine(SVM)’ models. Main results. The ‘ResNet 50+FLD model’ had Validation and Testing accuracy, of 99.5%, and 99.4% respectively. The Precision, Sensitivity, Specificity, F-measure, and G- mean values were computed as well. The comparative analysis of the filters revealed that the BF performed better than the MAF. The ‘BSCA’ performed better with the SVM classifier, than the DT classifier, with validation accuracy, and testing accuracy of 99.5%, and 98.83%, respectively. Significance. The ever-increasing number of critical cases and the limited availability of skilled medical attendants, advocates in favor of an automated and harmless health monitoring system. The proposed methodology is completely contactless, thus eliminating the risk of infections that spread through contact. There is a wide scope of using this methodology in complete darkness, and in remote areas as well, where there is a lack of medical attendants.

Abstract. Aerosol particles are of importance in the Earth's radiation budget since they scatter and absorb sunlight. While extensive studies of aerosol optical properties have been conducted at ground sites, vertical measurements and characterization are very limited in megacities. In this work, we present simultaneous real-time online measurements of aerosol optical properties at ground level and at 260 m on a meteorological tower from 16 November to 13 December in 2016 in Beijing along with measurements of continuous vertical profiles during two haze episodes. The average (±1σ) scattering and absorption coefficients (bsca and babs; λ=630 nm) were 337.6 (±356.0) and 36.6 (±33.9) Mm−1 at 260 m, which were 26.5 % and 22.5 % lower than those at ground level. Single scattering albedo (SSA), however, was comparable between the two heights, with slightly higher values at ground level (0.89±0.04). Although bsca and babs showed overall similar temporal variations between ground level and 260 m, the ratios of 260 m to ground varied substantially from less than 0.4 during the clean stages of haze episodes to > 0.8 in the late afternoon. A more detailed analysis indicates that vertical profiles of bsca, babs, and SSA in the low atmosphere were closely related to the changes in meteorological conditions and mixing layer height. The mass absorption cross section (MAC) of equivalent black carbon (eBC, λ=630 nm) varied substantially from 9.5 to 13.2 m2 g−1 in winter in Beijing, and it was strongly associated with the mass ratio of coating materials on refractory BC (rBC) to rBC (MR), and also the oxidation degree of organics in rBC-containing particles. Our results show that the increases in MAC of eBC in winter were mainly caused by photochemically produced secondary materials. Light absorption of organic carbon (brown carbon, BrC) was also important in winter, which on average accounted for 46 (±8.5) % and 48 (±9.3) % of the total absorption at 370 nm at ground level and 260 m, respectively. A linear regression model combined with positive matrix factorization analysis was used to show that coal combustion was the dominant source contribution of BrC (48 %–55 %) followed by biomass burning (17 %) and photochemically processed secondary organic aerosol (∼20 %) in winter in Beijing.

Background: Antimicrobials are among the most commonly prescribed medications in US hospitals; an estimated 50% of hospitalized patients receive an antimicrobial. Research has shown that antimicrobial prescriptions to vary by patient- and hospital-level factors; however, disparities by patient neighborhood characteristics have not been examined. We evaluated associations between hospital and neighborhood indicators of socioeconomic status (SES) and antimicrobial use (AU) for gram-positive bacterial infections (GPBs), and broad-spectrum use for community-acquired infections (BSCAs) and hospital-onset infections (BSHOs). Methods: This analysis was conducted among 86 acute-care hospitals in California that submitted AU data via the NHSN in 2019. Hospital-level AU was measured as standardized antimicrobial administration ratios (SAARs) calculated by dividing observed antimicrobial use by risk-adjusted predicted antimicrobial use for GPB, BSCA, and BSHO antimicrobial groupings and categorized as binary (>1 or <1); SAARs >1 indicate potential inappropriate prescribing. California Office of Statewide Health Planning and Development 2018 data were used to obtain hospital characteristics and patient age, race or ethnicity, insurance, and comorbidities (defined by Charlson comorbidity index) for hospitalizations where AU may have been indicated, based on International Classification of Diseases Tenth Revision (ICD-10) diagnosis codes. The California Healthy Places Index (HPI) was used to obtain composite neighborhood SES indicators for each patient at the ZIP code level, measured as tertiles. Covariates were aggregated to the hospital level. Poisson regressions were used to evaluate the association between hospital and neighborhood SES indicators and SAAR scores, controlling for potential hospital-level confounders. Results: Among 86 hospitals included in the analysis, the mean patient age for hospitalizations where AU may have been indicated was 66 years, the proportion of white patients was 55%, and the mean proportion of Medi-Cal users was 19%. After adjusting for confounders including age, race or ethnicity, insurance status, comorbidities, and number of hospital beds; higher median values of patient SES had a protective effect against hospitals having GP SAAR scores > 1 (relative risk [RR], 0.68; 95% CI, 0.50–0.93) but was not significantly associated with hospitals having BSCA SAAR scores >1 (RR, 0.79; 95% CI, 0.62–1.02) or BSHO SAAR scores >1 (RR, 0.80; 95% CI, 0.61–1.04). Conclusions: Considering SES in addition to summary antimicrobial use scores such as SAARs may help identify populations potentially at risk for inappropriate AU; however, patient-level information is still necessary to evaluate appropriateness of antimicrobial prescribing.Funding: NoDisclosures: None

Admission tests in college assess students’ readiness for the college level education while mock board examination evaluates readiness for the licensure examination. The performance of BS Customs Administration students in these two tests and their relationship to their performance in the Licensure Examination for Customs Brokers (LECB) were considered in the investigation. Using inferential statistics, scores in the entrance examination and ratings in the mock board examination of BSCA students for the past four years were correlated with their ratings in the LECB. A total of 66 students who graduated from 2011 to 2014 who took the licensure examination and with complete entrance exams and mock board exam records served as respondents of this study. Results revealed a positive significant relationship between the composite score in the admission test and students’ scores in the four subjects of the LECB: Customs Laws and Implementing Rules and Regulations; Tariff Laws and International Trade Agreements; Warehousing, Transportation and Cargo Handling Operations; and Practical Computations of Customs Duties, Taxes, and other charges. Ratings in the four subject areas of the mock board examination were also significantly related to scores in the equivalent subject areas of the LECB. The study concludes the importance of entrance tests as part of the admission policy in the BSCA program and the mock board examination in improving the performance of graduates in the Licensure Examination for Customs Brokers.

Abstract Background Inflammatory bowel disease(IBD) is a chronic disease. Although colonscopy is the gold standard for assessing activity, itcarries a considerable discomfort. We evaluate the value of bowel sound computational analysis (BSCA) as a tool in assist diagnosis and severity in Crohn’s disease(CD) and ulcerative colitis (UC). Methods We used homemade BSCA as a tool in assist bowel sound(BS). Five minutes recordings were taken for patients. The BS activity, sound duration, peak frequency (Hz) and bowel sound index (SI) was recorded. Results We enrolled 16 CD, 22 UC and 20 healthy controls. In CD patients, BS peak frequency was significantly higher than UC and controls (p=0.01). In UC patients, BS SI was significantly higher than CD and controls (mean 2024 V/min vs 1687 and 1181, p=0.04 and 0.01, respectively). We further evaluated the relation between these two parameters and the degree of severity. In CD patients, BS peak frequency were higher in patients with CDAI over 150 than CDAI under 150 (mean 370.7 Hz vs 358.2 Hz, p=0.045). In UC patients, BS SI was significantly higher in patients with mayo score(MS) larger than 6,compare to MS 3-5, MS 0-2, and controls (mean 2269 V/min vs 1863,1638, and1181, P all=0.01). Conclusion CD patients had higher BS peak frequency and UC patients had higher bowel sound index. These characteristic of BS changes seemed correlated to the severity of IBD.

Snakebites inflicted by the arboreal viperid snake Bothriechis schlegelii in humans are characterized by pain, edema, and ecchymosis at the site of the bite, rarely with blisters, local necrosis, or defibrination. Herein, a comparative study of Bothriechis schlegelii snake venoms from Colombia (BsCo) and Costa Rica (BsCR) was carried out in order to compare their main activities and to verify the efficacy of Bothrops antivenom produced in Brazil to neutralize them. Biochemical (SDS-PAGE and zymography) and biological parameters (edematogenic, lethal, hemorrhagic, nociceptive, and phospholipase A2 activities) induced by BsCo and BsCR snake venoms were evaluated. The presence of antibodies in Bothrops antivenom that recognize BsCo and BsCR snake venoms by enzyme-linked immunosorbent assay and Western blotting, as well as the ability of this antivenom to neutralize the toxic activities were also verified. SDS-PAGE showed differences between venoms. Distinctive caseinolytic and hyaluronidase patterns were detected by zymography. BsCo and BsCR showed similar phospholipase A2 activity. Strong cross-reactivity between BsCo and BsCR was detected using Bothrops antivenom with many components located between 150 and 35 kDa. BsCR was more edematogenic and almost fourfold more hemorrhagic than BsCo, and both venoms induced nociception. BsCR (LD50 5.60 mg/kg) was more lethal to mice than BsCo (LD50 9.24 mg/kg). Bothrops antivenom was effective in the neutralization of lethal and hemorrhagic activities of BsCo and BsCR and was partially effective in the neutralization of edematogenic and nociceptive activities. In conclusion, geographic distribution influences the composition and activities of Bothriechis schlegelii venoms. Bothrops antivenom cross-reacted with these venoms and was partially effective in neutralizing some toxic activities of BsCo and BsCR.

Abstract Background Clostridioides difficile infections (CDIs) are the most prevalent healthcare-associated infection in the U.S. Of all CDIs, most are related to healthcare exposures and are potentially preventable by reducing unnecessary antibiotic use and interrupting patient-to-patient transmission of CDI. Methods The adult SAARs for 4 antimicrobial agent categories were compared with the CDI SIR at 28 facilities with greater than 100 beds across the health system for the calendar year of 2018. The 4 adult antimicrobial agent categories chosen for comparison were: antibacterial agents posing the highest risk for CDI, broad-spectrum antibacterial agents predominantly used for hospital-onset infections (BSHO), broad-spectrum antibacterial agents predominantly used for community-acquired infections (BSCA) and all antibacterial agents. Results The 2018 aggregate CDI SIR for the 28 facilities was 0.609. The aggregate SAAR for the adult antimicrobial agent categories were 1.05 for the antibacterial agents posing the highest risk for CDI, 1.05 for BSHO, 0.88 for BSCA, and 1.03 for all antibacterial agents. No correlation was seen between any of the 4 adult SAAR antimicrobial agent categories and the facility CDI SIR (Figure 1–4). Conclusion While reducing unnecessary antibiotics is an important strategy in preventing CDIs, having a higher observed vs. predicted administration ratio in the four antimicrobial agent categories studied was not correlated with a higher CDI SIR, including the CDI SAAR category. Reduction of CDI is challenging requiring a multipronged approach to include infection control strategies, appropriate testing, and antimicrobial stewardship.

COVID-19 is evolving into one of the worst pandemics in recent history, claiming a death toll of over 1.5 million as of December 2020. In an attempt to limit the expansion of the pandemic in its initial phase, nearly all countries imposed restriction measures, which resulted in an unprecedented reduction of air pollution. This study aims to assess the impact of the lockdown effects due to COVID-19 on in situ measured aerosol properties, namely spectral-scattering (bsca) and absorption (babs) coefficients, black carbon (BC) concentrations, single-scattering albedo (SSA), scattering and absorption Ångström exponents (SAE, AAE) in Athens, Greece. Moreover, a comparison is performed with the regional background site of Finokalia, Crete, for a better assessment of the urban impact on observed differences. The study examines pre-lockdown (1–22 March 2020), lockdown (23 March–3 May 2020) and post-lockdown (4–31 May 2020) periods, while the aerosol properties are also compared with a 3–4 year preceding period (2016/2017–2019). Comparison of meteorological parameters in Athens, between the lockdown period and respective days in previous years, showed only marginal variation, which is not deemed sufficient in order to justify the notable changes in aerosol concentrations and optical properties. The largest reduction during the lockdown period was observed for babs compared to the pre-lockdown (−39%) and to the same period in previous years (−36%). This was intensified during the morning traffic hours (−60%), reflecting the large decrease in vehicular emissions. Furthermore, AAE increased during the lockdown period due to reduced emissions from fossil-fuel combustion, while a smaller (−21%) decrease was observed for bsca along with slight increases (6%) in SAE and SSA values, indicating that scattering aerosol properties were less affected by the decrease in vehicular emissions, as they are more dependent on regional sources and atmospheric processing. Nighttime BC emissions related to residential wood-burning were slightly increased during the lockdown period, with respect to previous-year means. On the contrary, aerosol and pollution changes during the lockdown period at Finokalia were low and highly sensitive to natural sources and processes.

The External Quality Control (EQC) is an important tool to ensure the Clinic Laboratory (CL) services quality. This way, the objective of this study was to evaluate the EQC in the hematology, parasitology and urinalysis sectors of Biomedical Clinic, at a Higher Education Institution from October 2011 to September 2012, through a descriptive study with a performance data collection in the National Quality Control Program (NQCP) from the Brazilian Society of Clinical Analyses (BSCA). The urinalysis sector presented the best percentage of accuracy, a 94,5%, while the hematology one obtained 86.15 % and the parasitology sector presented 58.83 % of accuracy. However, in general terms, Clínica Biomédica obtained 82.83 % fitting on the level of “Excellence”, according to the standards set by NQCP, underscoring the reliability of its analyzes. The continuity of the EQC implementation must be preserved to ensure accurate diagnosis, minimizing negative impacts to the patient’s health.

Sensory analysis or cup testing has been widely used in the coffee production chain for the validation of final quality. The tasters are responsible for defining the patterns and qualitative profiles of the drink based on the sensorial analysis and according to their gustatory sensibilities, which are often acquired by professional experience. However, the literature has not discussed in detail the relationship between the number of tasters and the consistency of sensorial analysis. Thus, using the bootstrap simulation methodology to estimate the optimum plot size, this study quantifies and proposes a specific number of tasters for the process of sensorial analysis of specialty coffees. The results indicate that the use of 6 tasters is sufficient to conduct sensorial analysis following SCA and BSCA protocol for coffees in the Arabica group, as well as 6 tasters for coil and Conilon coffees. From this number, no gains in precision are observed in the process of sensorial analysis of coffee with addition tasters.

This research evaluates the behavior corrosion of galvanized steel (GS) and AISI 1018 carbon steel (CS) embedded in conventional concrete (CC) made with 100% CPC 30R and two binary sustainable concretes (BSC1 and BSC2) made with sugar cane bagasse ash (SCBA) and silica fume (SF), respectively, after 300 days of exposure to 3.5 wt.% MgSO4 solution as aggressive medium. Electrochemical techniques were applied to monitor corrosion potential (Ecorr) according to ASTM C-876-15 and linear polarization resistance (LPR) according to ASTM G59 for determining corrosion current density (icorr). Ecorr and icorr results indicate after more than 300 days of exposure to the sulfate environment (3.5 wt.% MgSO4 solution), that the CS specimens embedded in BSC1 and BSC2 presented greater protection against corrosion in 3.5 wt.% MgSO4 than the specimens embedded in CC. It was also shown that this protection against sulfates is significantly increased when using GS reinforcements. The results indicate a higher resistance to corrosion by exposure to 3.5 wt.% magnesium sulfate two times greater for BSC1 and BSC2 specimens reinforced with GS than the specimens embedding CS. In summary, the combination of binary sustainable concrete with galvanized steel improves durability and lifetime in service, in addition to reducing the environmental impact of the civil engineering structures.

Biological soil crusts (BSCs) are a major functional vegetation unit, covering extensive parts of drylands worldwide. Therefore, several multispectral indices have been proposed to map the spatial distribution and coverage of BSCs. BSCs are composed of poikilohydric organisms, the activity of which is sensitive to water availability. However, studies on dry and wet BSCs have seldom considered the mixed coverage gradient that is representative of actual field conditions. In this study, in situ spectral data and photographs of 136 pairs of dry and wet plots were collected to determine the influence of moisture conditions on BSC coverage detection. Then, BSC spectral reflectance and continuum removal (CR) reflectance responses to wetting were analyzed. Finally, the responses of four commonly used indices (i.e., normalized difference vegetation index (NDVI); crust index (CI); biological soil crust index (BSCI); and band depth of absorption feature after CR in the red band, (BD_red)), calculated from in situ hyperspectral data resampled to two multispectral data channels (Landsat-8 and Sentinel-2), were compared in dry and wet conditions. The results indicate that: (i) on average, the estimated BSC coverage using red-green-blue (RGB) images is 14.98% higher in wet than in dry conditions (P < 0.001); (ii) CR reflectance features of wet BSCs are more obvious than those of dry BSCs in both red and red-edge bands; and (iii) NDVI, CI, and BSCI for BSC coverage of 0%–60% under dry and wet conditions are close to those of dry and wet bare sand, respectively. NDVI and BD_red cannot separate dead wood and BSC with low coverage. This study demonstrates that low-coverage moss-dominated BSC is not easily detected by the four indices. In the future, remote-sensing data obtained during the rainy season with red and red-edge bands should be considered to detect BSCs.

Neural networks and deep learning have been successfully applied to tackle problems in drug discovery with increasing accuracy over time. There are still many challenges and opportunities to improve molecular property predictions with satisfactory accuracy even further. Here, we proposed a deep-learning architecture model, namely Bidirectional long short-term memory with Channel and Spatial Attention network (BCSA), of which the training process is fully data-driven and end to end. It is based on data augmentation and SMILES tokenization technology without relying on auxiliary knowledge, such as complex spatial structure. In addition, our model takes the advantages of the long- and short-term memory network (LSTM) in sequence processing. The embedded channel and spatial attention modules in turn specifically identify the prime factors in the SMILES sequence for predicting properties. The model was further improved by Bayesian optimization. In this work, we demonstrate that the trained BSCA model is capable of predicting aqueous solubility. Furthermore, our proposed method shows noticeable superiorities and competitiveness in predicting oil–water partition coefficient, when compared with state-of-the-art graphs models, including graph convoluted network (GCN), message-passing neural network (MPNN), and AttentiveFP.

The article provides a preliminary screening of Asian locust larvae aged 2-3 years for the virulence of 25 isolates isolated from insects belonging to different systematic groups of fungi Beauveria bassiana. Five of the 25 strains showed high biological activity against larvae, (BCo1-14, BSc1-15, BSc2-15, BTr1-16, BPit-16) reaching a mortality rate of 90-100% 21 days after inoculation. The strains that have the best effect on the level and rate of mortality of the host organism are - BCo1-14, BSc1-15, BSc2-15, BTr1-16, BPit-16. The greatest biological activity was observed in the BSc1-15 strain, as the mortality rate of test organisms was only 100% within 15 days of exposure. The lowest activity was shown by the BCi4-14 strain in the range of 35.0-62.5%. At the same time, the mortality rate of Asian locust larvae in the control variant (without treatment) for 21 days was 15.0±2.88%. Thus, the proportion of highly toxic forms (80-100% lethality) in the total number of studied strains was not more than 44%, and the proportion of mildly toxic forms (less than 80% activity) was 56%.

In recent days, many integrated circuits (ICs) are operated parallelly to increase switching operations in on-chip static random access memory (SRAM) array, due to more complex tasks and parallel operations being executed in many digital systems. Hence, it is important to efficiently identify the long-duration unused ICs in the on-chip SRAM memory array layout and to effectively distribute the task to unused ICs in SRAM memory array. In the present globalization, semiconductor supply chain detection of unused SRAM in large memory arrays is a very difficult task. This also results in reduced lifetime and more power dissipation. To overcome the above-mentioned drawbacks, an efficient unused integrated circuits detection algorithm (ICDA) for parallel scan architecture is proposed to differentiate the ‘0’ and ‘1’ in a larger SRAM memory array. The proposed architecture avoids the unbalancing of ‘0’ and ‘1’ concentrations in the on-chip SRAM memory array and also optimizes the area required for the memory array. As per simulation results, the proposed method is more efficient in terms of reliability, the detection rate in both used and unused ICs and reduction of power dissipation in comparison to conventional methods such as backscattering side-channel analysis (BSCA) and network attached storage (NAS) algorithm.

Biological soil crusts (BSCs) play an essential role in desert ecosystems. Knowledge of the distribution and disappearance of BSCs is vital for the management of ecosystems and for desertification researches. However, the major remote sensing approaches used to extract BSCs are multispectral indices, which lack accuracy, and hyperspectral indices, which have lower data availability and require a higher computational effort. This study employs random forest (RF) models to optimize the extraction of BSCs using band combinations similar to the two multispectral BSC indices (Crust Index-CI; Biological Soil Crust Index-BSCI), but covering all possible band combinations. Simulated multispectral datasets resampled from in-situ hyperspectral data were used to extract BSC information. Multispectral datasets (Landsat-8 and Sentinel-2 datasets) were then used to detect BSC coverage in Mu Us Sandy Land, located in northern China, where BSCs dominated by moss are widely distributed. The results show that (i) the spectral curves of moss-dominated BSCs are different from those of other typical land surfaces, (ii) the BSC coverage can be predicted using the simulated multispectral data (mean square error (MSE) < 0.01), (iii) Sentinel-2 satellite datasets with CI-based band combinations provided a reliable RF model for detecting moss-dominated BSCs (10-fold validation, R2 = 0.947; ground validation, R2 = 0.906). In conclusion, application of the RF algorithm to the Sentinel-2 dataset can precisely and effectively map BSCs dominated by moss. This new application can be used as a theoretical basis for detecting BSCs in other arid and semi-arid lands within desert ecosystems.

With the objective to produce efficient workforce, the primordial goal of the Bachelor of Science in Customs Administration (BSCA) educational program is to produce ethical and socially responsible customs broker professionals whose skills and competence conform to, and are compliant with, international standards and best customs practices (CHED, 2017). Prior to putting all the basic and fundamental knowledge of customs into practice, students ought to attend a technical course to review the essential aspects of the customs profession. As such, this course serves as a preparation for students in taking the Customs Broker Licensure Examination (CBLE). At the Asian Institute of Maritime Studies (AIMS), this is covered under the Customs and Tariff (CUSTAR 425) course. There are essential aspects that may affect the performance of students in engaging with this course: learning materials, and effective professors. Right (2018) reiterated that learning materials are crucial to the success of student achievement while the biggest opportunity for faculty members to impact, inspire, and engage students (Koproske, 2016) is by mapping concrete skills and outcomes to the syllabi in order to help their departments systematically measure and improve the learning experiences of their students over time. This led the researchers to examine the performance, effectiveness and management of the Customs and Tariff course (CUSTAR 425) of AIMS. Applying the tenets of descriptive-survey design, the study gathered data from 198 BSCA students of AIMS who were enrolled in CUSTAR 425 during SY 2015-2016 to 2017-2018. Employing total enumeration as sampling technique, all members of the population were measured in terms of their performance (using final grade as data) in CUSTAR 425, as well as their assessment on the effectiveness and management (utilizing a self-made questionnaire) of the above course. With the aid of SPSS (version 23), data were derived using mean (for grades) and average weighted mean (for effectiveness and management). In terms of performance, majority of the students earned “Good” grades (83 to 85) in CUSTAR 425 while the effectiveness of the course was also favorably rated by the respondents specifically on the following indicators: Course Content (M=4.12) and Course Materials (M=3.94). However, though generally perceived that the Course Timeline aspect have helped them in preparing for the exam, a fraction of students however thought otherwise (neutral and/or disagree) as indicated by the slightly low mean of 3.78. Perhaps, two issues can be raised on this part: insufficient time allotted to complete the course; or, time management skill of students. Lastly, yielding a composite mean of 4.20 (Agree), the students generally agreed that the Customs Administration Department has efficiently managed the CUSTAR 425 course. In consideration of the results, it is recommended that the Customs Administration Department shall strategically set reasonable course timeline to facilitate learning and enhance students’ knowledge. Perhaps, course topics shall also be revisited and calibrated in order to streamline course contents and make fit with the allotted timeline. Students who are planning to take a licensure examination are also advised to enhance their time management skills and learn to properly schedule their school activities especially extending priority to requirements that need more time and attention. Lastly, AIMS, through the Customs Administration Department, shall maintain the good management of the course as majority of its elements was favorably assessed.

Background: Basaloid skin tumors include subtypes of basal cell carcinoma (BCC) and the basaloid variant of squamous cell carcinoma (SCC). Due to their similarity in pathology and clinical presentation, their diagnosis is not straightforward. The aim of this study was to analyze the immunohistochemical expression of HSP105 in basaloid skin tumors, which include BCC, basosquamous carcinoma (BSC), metatypical basal cell carcinoma (MBCC), basaloid squamous cell carcinoma (BSCC), BCC with squamous differentiation as well as conventional SCC. Methods: This retrospective study included 17 cases of BCC, 11 cases of BSC, 8 instances of MBCC, 10 cases of BCC with squamous differentiation, 8 cases of BSCC, and 19 cases of SCC. Their clinical characteristics were summarized, and the paraffin blocks of tumor biopsy specimens were collected for HSP105 immunostaining. Results: In contrast to the BCC group, which stained predominantly negative, SCC stained diffusely positive for HSP105. BSCs showed some areas of HSP105 positivity with a transitional expression signature. HSP105 was only weakly positive in a few cases of MBCC. Although BSCC was stained positive for HSP105, the HSCORE was significantly lower than that of the classic SCC. In BCC with squamous differentiation, focal staining for HSP105 was only seen in the area of squamous differentiation. Conclusion: There was a difference in immunohistochemical staining of HSP105 in basaloid skin tumors which helps in differential diagnosis. Differentiation between BCC, SCC, BSCC, MBCC, and BCC with squamous differentiation can be aided by immunohistochemistry using HSP105.

°Abstract. In order to develop new cathodes for reduced temperature SOFCs, Ba0.5Sr0.5Co0.8Fe0.2O3-δ-Ag composite cathode was investigated in intermediate-temperature Solid Oxide Fuel Cells (IT-SOFCs). The XRD results suggested that no chemical reactions between BSCF and Ag in the composite cathode were found. The resistance measurements showed that the addition of Ag into BSCF improved electrical conductivity of pure BSCF, and the improved conductivity resulted in attractive cathode performance. In addition, electrochemical impedance spectra exhibited the better performance of BSCF-Ag composite cathodes than pure BSCF, e.g., the polarization resistance value of BSCF-Ag was only 0.36Ω cm2 at 650°C, which was nearly 80% lower than that of BSCF electrode. Polarization curves showed the overpotential decreased with the addition of Ag. The current density value of BSCF-Ag was 0.88Acm-2 under –120mV, about five times of that BSCF measured at 650°C. As a summary, compared to a pure BSCF cathode, it was found that adding Ag in the cathode enhanced the BSCF performance significantly.

The Brief Self-Control Scale (BSCS) developed by Tangney, Baumeister, and Boone (2004) is a widely used measure of trait self-control. The present study aimed to validate Italian version of the BSCS. 262 Italian university students completed BSCS along with measures of grit, impulsive behavior, self-esteem, resilience, and psychological distress. 143 of the first sample completed BSCS after three weeks again. Results indicated that the Italian version of the BSCS is one-dimensional as the original BSCS. Good internal consistency and test-retest stability were documented. Convergent and divergent validity of the construct was established with the association between BSCS and measures of grit and impulsive behavior. Furthermore, predictive validity assessment showed that BSCS positively predicted self-esteem and resilience, and negatively predicted psychological distress as expected. In conclusion, findings suggest that the Italian BSCS is a reliable and valid instrument assessing trait self-control in Italian speaking populations.

Biological soil crusts (BSCs) hold promise for reducing soil erosion in subtropical forest plantations, and microorganisms profoundly affect the formation and development of BSCs. The effects of biochar as a soil conditioner on the diversity and structure of soil microbial communities in BSCs are largely unknown. Therefore, our aim was to determine how biochar might improve microbial community composition and BSC function. Herein, a field experiment was conducted in a P. massoniana plantation; the addition of biochar was the treatment, and no biochar addition was the control (CK). Soil microbial communities associated with moss BSCs (in and beneath BSCs) with and without the addition of biochar were analyzed by Illumina sequencing technology. The results showed that Acidobacteria (28.35%), Proteobacteria (22.53%), Actinobacteria (17.41%), and Chloroflexi (16.74%) were the dominant bacterial phyla, whereas Basidiomycota (70.00%) and Ascomycota (22.76%) were the dominant fungal phyla in BSCs. The soil bacterial and fungal OTU number and richness in BSCs were higher than those beneath BSCs. The relative abundances of Acidobacteria, Chloroflexi, and Basidiomycota were higher in BSCs than beneath BSCs, whereas the relative abundances of Actinobacteria, Firmicutes, Ascomycota, and Chytridiomycota showed the opposite trend. Beneath BSCs, biochar addition increased the soil bacterial OTU number and richness (ACE index and Chao1) but decreased the soil fungal OTU number and richness. Biochar had little effect on soil microbial community structures in BSCs; however, beneath BSCs, it significantly increased the relative abundances of Acidobacteria, Chloroflexi, and Basidiomycota and significantly decreased the relative abundances of Actinobacteria, Firmicutes, Ascomycota, and Chytridiomycota. Biochar-induced changes in soil microbial communities were related to soil environmental factors, especially urease activity, organic matter content, pH, total nitrogen content, and sucrase activity. We demonstrated the different effects of biochar on soil microbial communities in and beneath the BSCs of subtropical forest plantations; these findings provided new insights into soil stabilization with BSCs below the forest canopy in subtropical regions.

This study presents the preparation of barium strontium cobalt ferrite (BSCF)–samarium doped ceria (SDC) added samarium doped ceria carbonate (SDCC) cathode for solid oxide fuel cell (SOFC). The aim of this study is to investigate the effect of heat treatment on compatibility and characterization of BSCF composite. Calcined BSCF was mixed with SDCC and SDC by ball milling at 150 and 200 rpm respectively. Subsequently, both were uniaxially pressed to form pellets and sintered at 600°C for 2 hours. The BSCF behavior of composite samples was characterized via X-ray diffraction to determine the crystalline phase of BSCF composite. Fourier transform infrared spectroscopy was used to determine the existence of carbonate bond. Field emission scanning electron microscopy was used to examine the grain morphology. The crystalline BSCF phase percentage increased and secondary phases reduced when the milling speed decreased. After milling, BSCF composites still displayed uniform elemental distribution. Heat treatment has an impaired crystalline phase of perovskite BSCF. Without heat treatment, the BSCF composites showed agglomerate and unmolded particles.

Although an extensive professional literature exists on biological soil crusts (BSCs), especially on the species composition of hetero- and autotrophs forming the micro-biological comunity, micromorphological information on BSCs is extremely scarce. In our study, we focused on microstructure of the BSCs from the James Ross Island (Antarctica). We combined the approach of digital microscopy to study surface roughness of the BSCs with taxonomy of BSC-forming autotrophs and chlorophyll fluorescence study focused on the photosynthetic functioning of BSCs when exposed to controlled UV-B stress. Microprofiling of BSCs resulted in the finding that the examined BSCs might be classified as fine-grained surface with roughness characteristics: Ra (37.9 μm) and Rz (136.9 μm). The BSCs were rich in microautotrophs, both algae and cyanobacteria, however, Microcoleus sp. was found dominating species. It formed multifilament ropes on and inside the BSCs. Under UV-B stress, Microcoleus- and Nostoc-dominated BSC parts showed similar sensitivity and acclimatory response so long-term UV-B treatment, however, Microcoleus seemed to be slightly more sensitive to UV-B. Microcoleus-dominated parts of BSCs showed less pronounced acclimation to UV-B treatment than Nostoc-dominated parts. It was reflected in lower values of maximum (FV/FM) and effective (FPSII) quantum yields recorded after 6 d exposition.

After multiple prediction, adaptive multiple subtraction is essential for the success of multiple removal. The 3D blind separation of convolved mixtures (3D BSCM) method, which is effective in conducting adaptive multiple subtraction, needs to solve an optimization problem containing L1-norm minimization constraints on primaries by the iterative reweighted least-squares (IRLS) algorithm. The 3D BSCM method can better separate primaries and multiples than the 1D/2D BSCM method and the method with energy minimization constraints on primaries. However, the 3D BSCM method has high computational cost because the IRLS algorithm achieves nonquadratic optimization with an LS optimization problem solved in each iteration. In general, it is good to have a faster 3D BSCM method. To improve the adaptability of field data processing, the fast iterative shrinkage thresholding algorithm (FISTA) is introduced into the 3D BSCM method. The proximity operator of FISTA can solve the L1-norm minimization problem efficiently. We demonstrate that our FISTA-based 3D BSCM method achieves similar accuracy of estimating primaries as that of the reference IRLS-based 3D BSCM method. Furthermore, our FISTA-based 3D BSCM method reduces computation time by approximately 60% compared with the reference IRLS-based 3D BSCM method in the synthetic and field data examples.

PurposeThe aim of this research is to propose a buffer sizing and buffer controlling algorithm (BSCA) as a heuristic algorithm for calculating project buffer and feeding buffers as well as dynamic controlling of buffer consumption in different phases of a wind power plant project in order to achieve a more realistic project duration.Design/methodology/approachThe BSCA algorithm has two main phases of planning and buffer sizing and construction and buffer consumption. Project buffer and feeding buffers are determined in the planning and buffer sizing phase, and their consumption is controlled in the construction and buffer consumption phase. The heuristic algorithm was coded and run in MATLAB software. The sensitivity analysis was conducted to show the BSCA influence on project implementation. Then, to evaluate the BSCA algorithm, inputs from this project were run through several algorithms recently presented by researchers. Finally, the data of 20 projects previously accomplished by the company were applied to compare the proposed algorithm.FindingsThe results show that BSCA heuristic algorithm outperformed the other algorithms as it shortened the projects' durations. The average project completion time using the BSCA algorithm was reduced by about 15% compared to the previous average project completion time.Originality/valueThe proposed BSCA algorithm determines both the project buffer and feeding buffers and simultaneously controls their consumption in a dynamic way.

Abstract Patch testing is an important tool in the assessment of facial dermatitis. The cosmetic or facial series of haptens are highly relevant in facial dermatitis. The British Society for Cutaneous Allergy has recently updated the facial series to include the reduced number of 24 haptens. We compared positive allergens found in the Chemotechnique Cosmetic series (60 haptens) with that of the British Society for Cutaneous Allergy (BSCA) facial series. We conducted a retrospective review of patients who were patch tested to the Chemotechnique Cosmetic series over a 30-month period. We recorded and compared positive contact allergens in this series with that of the BSCA facial series. Sixty-three patients were patch tested to the Chemotechnique Cosmetic series over a 30-month period. Twenty-one patients were diagnosed with at least one positive contact allergen. In total, 35 contact allergies were diagnosed. Contact allergen positivity was seen to sorbitan oleate (Span 80; positive rate 4.7%), thimerosal (Merthiolate; positive rate 4.7%), chloroacetamide (positive rate 4.7%), hexahyrdo-1,3,5-tris(2-hydroxyethyl) triazine (Groton BK; positive rate 4.7%), abitol (hydroabietyl alcohol; positive rate 9.5%), benzophenon-3 (Eusolex® 4360, EscalolTM 567, oxybenzone; positive rate 4.7%), sorbitan sesquioleate (positive rate 14.2%), benzyl salicylate (positive rate 9.5%), tert-butyl hydroquinone (positive rate 14.2%), tea tree oil oxidized (positive rate 4.7%), 3-(dimethylamino)-1-propylamine (positive rate 4.7%), Amerchol (positive rate 4.7%), quaternium (positive rate 4.7%), methyldibromo glutaronitrile (MDBGN; positive rate 9.5%), methylisothiazolinone (MI; positive rate 4.7%), sodium metabisulfite (positive rate 28.5%) and gallate mix (positive rate 28.5%). Nine patients (43%) were found to have more than one contact allergy. Five of the positive haptens (Amerchol, quaternium, MDBGN, MI and sodium metabisulfite) are captured within the BSCA standard series but are not found within the BSCA facial series. Benzophenone 3 is captured within the BSCA extra facial series. Five further haptens [sorbitan oleate (Span 80), thimerosal (Merthiolate), chloroacetamide, hexahyrdo-1,3,5-tris(2-hydroxyethyl) triazine (Groton BK) and benzyl salicylate] were captured with the Chemotechnique series. However, these five are not included in the BSCA facial series and would not otherwise have been identified. Seventeen per cent of contact allergies would not have been diagnosed in this study if the BSCA facial series had been applied. This study highlights the variation in positivity seen between the Chemotechnique and BSCA facial series and the potential for missed diagnoses.

Abstract Background Patch testing is an important investigation when dermatitis is unresponsive to, or worsened by, topical corticosteroid treatment. There is a balance to be struck between testing too many allergens, which is expensive, time consuming and risks causing sensitization, and testing too few, which risks missing the diagnosis. The current British Society for Cutaneous Allergy (BSCA) corticosteroid series comprises eight allergens and was last updated in February 2007. Aim To review and update the BSCA corticosteroid series. Methods We retrospectively analysed data from 16 patch test centres in the UK and Ireland for all patients who were patch tested to a corticosteroid series between August 2017 and July 2019. We recorded the allergens tested, the number and percentage tested to a corticosteroid series and the number of positive results for each allergen. We identified the allergens that test positive in ≥ 0.1% of selectively tested patients. Results Overall, 3531 patients were tested to a corticosteroid series in the 16 centres. The number of allergens tested ranged from 7 to 18 (mean 10). The proportion of patch test patients who were tested to a corticosteroid series ranged from 1% to 99%. Six allergens in the 2017 BSCA series tested positive in ≥ 0.1% of patients. Nine allergens not in the BSCA corticosteroid series tested positive in ≥ 0.1% of patients. Conclusion This audit demonstrates the importance of regular review of recommended series and the significant variations in practice. The new BSCA corticosteroid series that we recommend contains 13 haptens, with the addition of the patient’s own steroid creams as appropriate.

Abstract It is estimated that one-fifth of the general population may have allergic contact dermatitis (ACD) to common environmental allergens. Skincare companies are increasingly advertising their products as ‘hypoallergenic’, targeting consumers who seek personal care products (PCPs) that are less likely to cause an allergic reaction. However, there are no Food and Drug Administration standards to regulate the use of the term hypoallergenic, allowing manufacturers to use the term freely. We evaluated PCPs marketed as hypoallergenic from two health and beauty retailers in the UK for the presence of allergens in the British Society of Cutaneous Allergy (BSCA) baseline series. Product and ingredient lists were obtained from www.boots.com and www.superdrug.com in November 2022 using the term hypoallergenic in the search box. PCPs without the term hypoallergenic in the product description, unrelated products (plasters, jewellery, sanitary towels, tampons, clothing, facial brushes) and duplicates (same products in different sizes) were excluded. In total, 208 PCPs met the inclusion criteria: 47 (22.6%) were rinse-off and 161 (77.4%) were leave-on products. At least one substance from the BSCA baseline series was an ingredient in 79 (38.0%) PCPs. Of these, 54 (26.0%) had 1 potential allergen, 21 (10.2%) had 2, and 4 (1.9%) had 3 potential allergens from the series. The frequently encountered allergens were cetearyl alcohol and paraben mix, found in 42 (20.4%) and 37 (18.0%) of products, respectively. Other BSCA baseline series allergens identified in PCPs included 2-bromo-2-nitropropane-1,3-diol, lanolin, decyl glucoside, diazolidinyl urea, methylisothiazolinone, limonene and linalool. In addition, PCPs had chemicals that were related to and may cross-react with allergens in the BSCA baseline series. Parfum/fragrance, which can cross-react with fragrance mix I and II, was found in 85 (41.3%) PCPs. Sodium benzoate and/or benzoic acid, often used as preservatives in PCPs, were found in 66 (32.0%) products. Forty (19.4%) PCPs had ingredients that belong to the Asteraceae family and therefore may trigger an ACD in those with positive reaction to Compositae and/or sesquiterpene lactone mix. Twenty-three (11.2%) PCPs contained cetyl alcohol and/or stearyl alcohol, the two major components of cetearyl alcohol. Overall, 153 (74.3%) of 206 PCPs marketed as hypoallergenic contained BSCA baseline series allergens or ingredients that may cross-react with them. This highlights the need to increase public awareness and education about the potential dangers of purchasing ‘hypoallergenic’ PCPs.

This research studies the performance of BSCA (Bachelor of Science in Customs Administration) graduates of the Asian Institute of Maritime Studies (AIMS) in the Customs Broker Licensure Examination (CBLE) from 2013 to 2022. The study purports to determine the performance of AIMS graduates in the subjects covered in the licensure examination. Moreover, this research aims to identify their strengths and weaknesses as well as to explore the relationship between year of examination and performance on the 4 core subjects. This research utilized a descriptive-correlational research design. The researchers analyzed the data gathered from CBLE results from (PRC). Specifically, the researchers include BSCA graduates of AIMS who took the CBLE from 2013-2022. The findings of this research revealed that the passing rate of AIMS BSCA examinees is below the required 75% passing rate, indicating a difficulty among AIMS graduates in passing their licensure exam. Furthermore, analysis of the subject areas demonstrated that customs laws, rules, regulations, ethics, and customs broker practices is the subject where the respondents perform the highest, while tariff classification and practical computations is the subject where respondents perform the weakest. In addition, statistical analysis of the data demonstrated significant differences in performance among the years for all four subjects. It also suggested a significant relationship between the year of examination and graduate performance in customs documentations, clearance, and procedures as well as tariff laws, rules, regulations. In conclusion, the study highlighted the importance of thorough preparation for the CBLE and suggests that examinees can gain an advantage by enhancing their knowledge and skills in specific subject areas of the CBLE. The findings emphasized the need for developing a program to improve CBLE performance. The study strongly recommends targeted interventions and initiatives to strengthen knowledge and skills in areas where respondents performed the weakest.

AbstractBackgroundAcrylate polymers and cross‐polymers (ACPs) are frequently used cosmetic ingredients. The British Society for Cutaneous Allergy (BSCA) and the UK Cosmetic, Toiletry and Perfumery Association (CTPA) collaborated to investigate the allergenic potential of three commonly‐used ACPs.ObjectivesThe objective of this study is to determine the prevalence of allergic contact dermatitis (ACD) to three ACPs: glyceryl acrylate/acrylic acid co‐polymer, sodium polyacrylate, and acrylates/C10‐30 alkyl acrylate cross‐polymer (Carbopol®).Materials and MethodsThe BSCA prospectively audited data collected from 20 centres in the UK and Ireland between 1st September 2021 and 1st September 2022. Patients with suspected ACD to (meth)acrylates, with facial dermatitis, or consecutive patients, were patch tested to glyceryl acrylate/acrylic acid co‐polymer 10% aqueous (aq.) sodium polyacrylate 2% aq., and to acrylates/C10‐30 alkyl acrylate cross‐polymer 2% aq. (Carbopol®). The frequencies of positive, irritant, and doubtful reactions were recorded.ResultsIn total, 1302 patients were patch tested. To glyceryl acrylate/acrylic acid co‐polymer, there was one doubtful reaction in a patient allergic to multiple (meth)acrylates, and one irritant. To sodium polyacrylate, there were four irritant reactions, one doubtful, and one positive reaction; in all cases, relevance was unknown and there was no demonstrable (meth)acrylate allergy. There were no reactions to Carbopol®.ConclusionsSensitisation to these concentrations of the three tested ACPs is rare. Elicitation of dermatitis in (meth)acrylate‐sensitised patients by exposure to these three ACPs appears unlikely.

It is imperative that examinees of professional licensures shall have certain level of intelligence and wit to pass the licensure examination, while corresponding higher education institutions (HEIs) shall cement the foundation of knowledge in various areas of expertise. The Customs Broker Licensure Examination (CBLE) is one of those examinations facilitated in by the Professional Regulation Commission (PRC) and undertaken by students who have completed a 4-year degree in Bachelor of Science in Customs Administration (BSCA). In the “5-Year AIMS Comparative Report of Customs Brokers Licensure Examination (CBLE) from 2017 to 2022,” there are inconsistencies that were observed in terms of the school’s achievement. More so, although there were years with passing marks, the passing rates, however, are not enough to be considered as an outstanding performance for the institution. Henceforth, by analysis of previous studies, pre-board review courses are important factors in achieving higher passing rates in licensure examinations. This led the proponents to analyze the performance in, and the correlation between, the Competency Assessment Course (CUSTAR 425) and the Customs Broker Licensure Examination (CBLE) of AIMS students from school years 2019, 2021 and 2022. Descriptive-correlation was used in determining the relationship between the CUSTAR 425 grades and the CBLE results of AIMS students. Outsourced from the Center for Research and Institutional Development (CRID) and the Center for Records and Certification (CRC), the CBLE exam and CUSTAR 425 grades came from sixty-one (61) BSCA graduates from school years 2019, 2021 and 2022. To analyze the data, frequency count, percentage, weighted mean and Pearson r were used. Based on the findings, majority of the BSCA graduates across the three school years had generally performed in CUSTAR 425 as evidenced by the following: 3 gained an “Excellent” achievement (96 to 100), 13 received a “Very Good” performance (90 to 95), and 24 earned a “Good” performance (84 to 89). However, the CBLE performance can be contextualized between fair to poor as only 27 had passed the licensure examination out of the 61 examinees. More so, although the school made a good passing rate of 56% when compared to the NPP of 46.46% in 2022, and 44% against the 40.08% NPP in 2019, these surpassing rates cannot be treated as good performances as the results did not meet the top performance qualifications of 50 or more examinees per year and with at least 80% overall passing percentage, as per PRC Commission Resolution No. 2017-1058 (C) series of 2017 (“November 2021 Customs Broker Licensure Examination,” 2021). In terms of correlation, no significant relationship exists between CUSTAR 425 and CBLE. Though the computed Pearson r of 0.25, and the p-value of 0.052, indicated a certain degree of relationship, the degree is however weak, hence, not significant. Strong recommendation is hereby given to the Customs Administration (CA) Department of AIMS to revisit and review its Competency Assessment Course (CUSTAR 425) and identify areas for enhancement. Perhaps, the department could ponder on the “five-step revision process” of McGahan (2018)

In June 2022, the U.S. federal government passed its first major firearm policy since the Brady Handgun Violence Prevention Act of 1993, the Bipartisan Safer Communities Act (BSCA). Summative content analysis was used to explore how the social problem of firearm violence was outlined in both policies, with the goal of extracting the social issue’s definition from the policies’ approaches to solving it. Both policies do not outline the various types of firearm violence, nor the disproportionate effect of firearm violence on certain populations. This work informs the role of federal policy in defining and monitoring firearm violence as a public health issue, identifying both individual and structural risk and protective factors from an asset-based lens, and allocating preventative efforts in communities that are most affected.

Abstract Personal care products (PCPs) commonly cause allergic contact dermatitis (ACD). Skincare companies often market their products as ‘hypoallergenic’ however this term is not regulated by industry standards. To determine whether PCPs marketed as hypoallergenic were truly less likely to precipitate ACD, we conducted a study of ingredients found in ‘hypoallergenic PCPs’ across two major UK retailers in 2022. Of 208 products meeting inclusion criteria, 153 (74%) contained at least one allergen or related chemical from the BSCA (British Society for Cutaneous Allergy) baseline series, 21 (10%) had two potential allergens and 4 PCPs (2%) had three allergens. Cetearyl alcohol was the commonest allergen identified in leave-on PCPs and parabens in rinse-off products; fragrance was the most frequent related chemical found in 85 PCPs (41%). A high prevalence of common allergens was found in hypoallergenic PCPs, suggesting that dermatologists and consumers should be cautious of product ingredients.

Twitter and Facebook are widely recognized as crucial tools for situational information during disasters. Given that the classification of disaster related tweets is computationally challenging due to the high dimension of textual data caused by the redundant and irrelevant features. Hence for optimal feature selection (FS) and classification of disaster tweets, this work utilizes binary salp swarm algorithm (BSSA) and proposed two enhancements over it (PBcSSA). The commensalism phase from symbiotic organisms search (SOS) is integrated with BSSA to enhance its feature space searchability and then its parallel implementation is done using Apache Spark framework to reduce the execution time. The experiments were performed in a cross-disaster setting on nine groups of datasets including biological, earthquake, flood, hurricane, industrial, societal, transportation, wildfire, and environmental. The proposed PBcSSA combined with the Naive Bayes (NB) classifier in wrapper mode and its performance is compared with standard BSSA, binary sine cosine algorithm (BSCA), binary particle swarm optimization (BPSO), binary grey wolf optimization (BGWO), and binary whale optimization algorithm (BWOA). The experimental results reveal that the proposed PBcSSA outperforms other algorithms in disaster tweet classification and achieved highest average F1-score with lowest feature set in a reduced execution time.

The article provides a preliminary screening of Asian locust larvae aged 2-3 years for the virulence of 25 isolates isolated from insects belonging to different systematic groups of fungi Beauveria bassiana. Five of the 25 strains showed high biological activity against larvae, (BCo1-14, BSc1-15, BSc2-15, BTr1-16, BPit-16) reaching a mortality rate of 90-100% 21 days after inoculation. The strains that have the best effect on the level and rate of mortality of the host organism are - BCo1-14, BSc1-15, BSc2-15, BTr1-16, BPit-16. The greatest biological activity was observed in the BSc1-15 strain, as the mortality rate of test organisms was only 100% within 15 days of exposure. The lowest activity was shown by the BCi4-14 strain in the range of 35.0-62.5%. At the same time, the mortality rate of Asian locust larvae in the control variant (without treatment) for 21 days was 15.0±2.88%. Thus, the proportion of highly toxic forms (80-100% lethality) in the total number of studied strains was not more than 44%, and the proportion of mildly toxic forms (less than 80% activity) was 56%.

Abstract Acrylate co-polymers are frequently used ingredients, believed to have low allergenic potential, present in a wide range of cosmetics, including skincare products, hairspray and nail varnish. Concerns have been expressed that individuals who are sensitized to (meth)acrylate monomers in ultraviolet (UV)-cured nail products may suffer elicitation reactions due to subsequent exposure to residual monomer impurities in acrylate co-polymers. The British Society for Cutaneous Allergy (BSCA) and the Cosmetic, Toiletry and Perfumery Association collaborated to investigate the allergenic potential of acrylate co-polymers. The BSCA prospectively audited data between 1 September 2021 and 1 September 2022 from the clinical databases of 20 patch test centres in the UK and Ireland, assessing the frequency of sensitization to three acrylate co-polymers. Patients with suspected or known allergy to (meth)acrylates and with facial dermatitis or (in some units) consecutive patients were tested to glyceryl acrylate/acrylic acid co-polymer 10% aqueous (aq.) (Lubrajel PF; United Guardian, Hauppauge, NY, USA), sodium polyacrylate 2% aq. (Cosmedia SP; BASF, Ludwigshafen, Germany) and EDT acrylates/C10-30 alkyl acrylate cross-polymer 2% aq. (Carbopol® ETD 2020 polymer; Lubrizol Advanced Materials, Wickliffe, OH, USA). During their manufacture, the pH of the patch test preparations was adjusted to within a range of 5.5–6.5. The antimicrobial preservative in the acrylate co-polymer patch test preparations, phenoxyethanol 1% aq. (Chemotechnique, Vellinge, Sweden), was also tested. Readings were carried out on days 2 and 4. The frequency of positive (1+/2+/3+), irritant and doubtful reactions was recorded. In total, 1302 patients were patch tested to the acrylate co-polymers. Of these, 335 were tested in addition to the (meth)acrylate series, 423 in addition to the facial and (meth)acrylate series and 277 in addition to the facial series and 267 were consecutively tested in addition to the baseline series. To glyceryl acrylate/acrylic acid co-polymer, there was one doubtful reaction in a patient allergic to multiple (meth)acrylates and one irritant reaction. To sodium polyacrylate, there were four irritant reactions, one doubtful reaction and one 1+ reaction; in all cases, relevance was unknown and there was no demonstrable (meth)acrylate allergy. There were no positive reactions to EDT acrylates/C10-30 alkyl acrylate cross-polymer. There was one irritant reaction to phenoxyethanol. In patients with positive patch test reactions to any (meth)acrylate (n = 67), there was no positive patch test to any acrylate co-polymer. Sensitization to these concentrations of acrylate co-polymers is rare. It is not possible to attribute dermatitis in (meth)acrylate-sensitized patients to a cosmetic ingredient with an International Nomenclature Cosmetic Ingredient name containing ‘acrylate co-polymer’.
