The Continuum of Support for Building Intimacy Knowledge in College for Students With Intellectual Disability
Authors: VanHorn Stinnett Chelsea , Plotner Anthony J. , Marshall Kathleen J. 
Published: November 2021

Abstract
Postsecondary education (PSE) programs allow for college students with intellectual disability to experience a higher level of autonomy in choice making, which they may not have experienced in their family home or high school. This includes choice making related to romantic and sexual relationships. The Continuum of Support for Intimacy Knowledge in College Survey (CoSIK-C) was used to examine how PSE programs support college students in building their intimacy knowledge. Types of resources and services used to build intimacy knowledge and the frequency and context in which support was provided were identified and varied across programs. Implications for practice and future research are provided.

Authors: Chowdhury Ishmum Zia , Amin Md. Nurul , Chowdhury Mashhud Zia , Rahman Sharar Muhib , Ahmed Mohsin , Cader F. Aaysha 
Published: November 2021

Background
Early revascularization and treatment is key to improving clinical outcomes and reducing mortality in acute myocardial infarction (AMI). In low- and middle-income countries such as Bangladesh, timely management of AMI is challenging, with pre-hospital delays playing a significant role. This study was designed to investigate pre-hospital delay and its associated factors among patients presenting with AMI in the capital city of Dhaka.

Methods
This retrospective cohort study was conducted on 333 patients presenting with AMI over a 3-month period at two of the largest primary reperfusion-capable tertiary cardiac care centres in Dhaka. Of the total patients, 239(71.8%) were admitted in the National Institute of Cardiovascular Diseases, Dhaka and 94(28.2%) at Ibrahim Cardiac Hospital & Research Institute, Dhaka Data were collected from patients by semi-structured interview and hospital medical records. Pre-hospital delay (median and inter-quartile range) was calculated. Statistical significance was determined by Chi-square test. Multivariate logistic regression analysis was done to determine the independent predictors of pre-hospital delay.

Results
The mean age of the respondents was 53.8±11.2 years. Two-thirds (67.6%) of the respondents were males. Median total pre-hospital delay was 11.5 (IQR-18.3) hours with median decision time from symptom onset to seeking medical care being 3.0 (IQR: 11.0) hours. Nearly half (48.9%) of patients presented to the hospital more than 12 hours after symptom onset. On multivariate logistic regression analysis, AMI patients with absence of typical chest pain [OR 5.21; (95% CI: 2.5–9.9)], diabetes [OR: 1.7 (95% CI: 1.0–2.9)], residing/staying > 30 km away from nearest hospital at the time of onset [OR: 4.3(95% CI = 2.3–7.2)] and belonged to lower and middle class [OR: 1.9(95% CI = 1.0–3.5)] were significantly associated with pre-hospital delays.

Conclusion
Acute myocardial infarction (AMI) patients with atypical chest pain, diabetes, staying far away from nearest hospital and belonged to lower and middle socioeconomic strata were significantly associated with pre-hospital delays. The findings could have immense implications for improvements about timely reaching of AMI patients to the hospital within the context of their sociodemographic status and geographic barriers of the city.
Abdominal Actinomycosis Abscess Presenting as an Isolated Gastrointestinal Pseudotumor
Authors: Clarrett Danisa , Ray Jennifer Michelle , Taylor Jason R. 
Published: November 2021

ABSTRACT

Actinomyces is a gram-positive anaerobic bacterium that is ubiquitous in nature. It typically presents as respiratory, cervicofacial, or abdominopelvic abscesses. We present a 66-year-old man with a progressive enlarging abdominal wall nodule concerning for malignancy. The patient had a negative workup, including an ultrasound-guided fine-needle aspiration and colonoscopy, with biopsy for a possible extension to the colonic wall. Diagnosis of an Actinomyces abscess was obtained through surgical resection with right hemicolectomy. He was successfully treated with a prolonged course of intravenous antibiotics. This is a rare case of an isolated abdominal wall Actinomyces abscess mimicking a gastrointestinal malignancy.

Authors: Bajaj Suryansh , Barrett Stevi M. , Nakhleh Raouf E. , Brahmbhatt Bhaumik , Bi Yan 
Published: November 2021

ABSTRACT
Novel chemotherapeutic agents are developed to treat recurrent/relapsed lymphoid malignancies. Umbralisib, a novel phosphatidylinositol 3-kinase inhibitor with a selective isoform binding, has shown an improved efficacy and safety profile in clinical trials. Immune-mediated colitis, a frequently observed dose-limiting adverse event of phosphatidylinositol 3-kinase inhibitors, has been mostly observed at supratherapeutic doses in the trials, with grade 1 or 2 diarrhea being the most common adverse event at the therapeutic dose (800 mg PO QD). We present a grade-3 colitis that can be attributed to umbralisib-mediated immune toxicity in a patient with chronic lymphocytic leukemia at the therapeutic dose.
Material Models to Study the Effect of Fines in Sandy Soils Based on Experimental and Numerical Results
Authors: Alnmr Ammar 
Published: November 2021

Choosing and calibrating a robust and accurate soil material model (constitutive model) is the first important step in geotechnical numerical modelling. A less accurate model leads to poor results and more difficulty estimating true behaviour in the field. Subsequent design work is compromised and may lead to dangerous and costly mistakes. In this research, laboratory experimental results were used as a basis to evaluate several soil material models offered in Plaxis2D software. The deciding feature of the soil model was how well it could represent effects of percentage of fine material within sandy soils to simulate its behaviour. Results indicate that the Hardening Soil (HS) model works well when the percentage of fine (soft) materials is less than 10%. Above that level, the Soft Soil model (SS) becomes the most suitable. Finally, some important conclusions about this research and recommendations for future research are highlighted.

Authors: Ahmed Salah 
Published: November 2021

Recently, there have been tremendous research outcomes in the fields of speech recognition and natural language processing. This is due to the well-developed multilayers deep learning paradigms such as wav2vec2.0, Wav2vecU, WavBERT, and HuBERT that provide better representation learning and high information capturing. Such paradigms run on hundreds of unlabeled data, then fine-tuned on a small dataset for specific tasks.
This paper introduces a deep learning constructed emotional recognition model for Arabic speech dialogues. The developed model employs the state of the art audio representations include wav2vec2.0 and HuBERT. The experiment and performance outcomes of our model overcome the previous known results.
Neue Forschungen zur Rekonstruktion der Schatzhäuser von Olympia – Ein Zwischenbericht
Authors: Wolf Markus 
Published: November 2021

Abstract
Since June 2018 the treasuries of the Archaic and early Classical period at Olympia in Southern Greece were explored. The new study is based on the unpublished works of the researcher Klaus Herrmann, who worked about the treasuries since 1968 and died in 2015, with the intention to prepare all the material and information for a final publication. For this reason, a new general plan of all the foundations and new drawings of series of architectural elements not yet recorded as well as computer graphics of the reconstruction of the treasuries were worked out. In this paper especially the treasury of Sikyon and its reused elements in the early Christian walls of the so called Spolienhaus as well as the easternmost treasury of Gela will be presented. Important for these two treasuries are also the older works of the researcher Hans Schleif in the period between 1937 and his death in 1945.
Überlegungen zu einer neu entdeckten Architekturzeichnung Michelangelos
Authors: Garbe Otfried 
Published: November 2021

AbstractThe author presents a newly discovered architectural drawing which shows one of the two identical portals in the reading room of the Biblioteca Laurenziana in Florence. The drawing is attributed to Michelangelo by the author and compared with two other drawings by the artist, one of which connects the Cloister with the vestibule of the Library and another that leads from the vestibule to the reading room. The present drawing has close visual similarities with both the drawings generally accepted as Michelangelo’s. However, it is distinguished by a double pediment that combines a triangular structure with a rounded one. In addition, it is designed in a perspectival manner that takes into account the depth of the opening and of its pediment. All three drawings have the same overall proportions, corresponding to the ›divina proportione‹. The openings in the three drawings have a quotient that is identical with the square root of five. The handwriting within the opening appears to be identical with Michelangelo’s hand.
Parallels in German, Austrian and Hungarian Town-Hall-Architecture during the Austrian-Hungarian Monarchy (1867–1918)
Authors: Megyeri-Pálffi Zoltán , Marótzy Katalin 
Published: November 2021

AbstractOur study focuses on the development of Central European town-hall-architecture from the 1860s to the First World War. We compare the town-hall-architecture of two countries: the Austro-Hungarian Monarchy (1867) and Germany (1871). Both states were born pursuant to public law in this period, as well. This fact as well as the similar political, economic and cultural conditions led to similar public construction works. The increasing power of the bourgeoisie was also reflected by architecture; therefore a large number of town halls were built in this period.In our study, we analyse the functional system and the architectural design of the town halls of this region based on their façades, style and mass, thus placing the close cultural relations of the two states subject to our examination into a new perspective.
Recreational Marijuana Sales Legalization and Monday Work Injury Claims
Authors: Dong Xiuming 
Published: November 2021

Abstract
An important stylized fact in the literature is that more Workers’ Compensation claims for difficult-to-diagnose injuries are filed on Monday than on any other day of the week. This paper studies the impact of recreational marijuana sales legalization on Monday work injury claims. Using restricted-use Workers’ Compensation claim data in Oregon and a Difference-in-Differences (DiD) model, I find the probability of overall Monday injuries increase by 4 percentage points after recreational marijuana sales legalization. The event study graphs suggest the medium-term effects appear to equal the short-term effects. Additionally, I do not find strong evidence to support those difficult-to-diagnose Monday injuries disproportionately increase after recreational marijuana sales legalization, suggesting a limited moral hazard of Monday injury claiming behavior after recreational marijuana sales legalization.

Authors: Onwudiwe Damian C. , Adeyemi Jerry O. , Papane Rebecca T. , Bobinihi Felicia F. , Hosten Eric 
Published: November 2021

Abstract
Zinc sulphide nanoparticles represented as ZnS1, ZnS2 and ZnS3 have been prepared from Zn(ii) N-methyl-N-ethanoldithiocarbamate (1) complex and its 2,2′-bipyridine (2) and 1,10′-phenanthroline (3) adducts, respectively. Both the parent complex (1) and the adducts (2) and (3) were characterised by spectroscopic techniques and elemental analysis. In the solid state, the structures of complexes (1) and (2) were established using single-crystal X-ray analysis. Complex (1) possessed a distorted trigonal bipyramidal geometry about the zinc centre, whilst forming a dimer via bidentate bridging coordination between two opposite dithiocarbamate motifs. On the other hand, complex (2) formed a trigonal prismatic geometry about the Zn centre with a ZnS4N2 chromophore. The decomposition of the complexes in hexadecylamine afforded spherical-shaped ZnS nanoparticles of the cubic sphalerite crystal phase. The transmission electron microscopy (TEM) micrographs showed that the average particles size of ZnS1, ZnS2 and ZnS3 were 2.63, 5.27 and 6.52 nm, respectively. In the optical study, the estimated bandgap energies were found in the range between 4.34 and 4.08 eV, which indicated a blue shift when compared with the bandgap energy of bulk ZnS.

Published: November 2021

Abstract
In this study, 2D TiC nanosheets were successfully synthesized by reacting carbon black and Ti2AlC in a molten NaCl/KCl eutectic salt. The effects of salt content and ratio of raw materials on the phase composition and purity of TiC products were systematically investigated. Results showed that carbon black enhanced the total decomposition of Ti2AlC to TiC, Al, and Al3Ti at 1100 °C. The introduction of molten salt ensured the formation of TiC nanosheets. Excess carbon influenced the synthesis of high TiC content by removing the Al and Al3Ti by-products. TiC nanosheets had a thickness of approximately 10–20 nm and a length of approximately 150–200 nm. A possible synthesis mechanism of TiC nanosheets was proposed.

Published: November 2021

Abstract
A rapid, simple and economical spectrofluorimetric method for the determination of diclofenac potassium in pure form, in pharmaceutical preparations and in human plasma has been developed. The method is based on the enhancement of the fluorescence signal of diclofenac potassium by the addition of sodium dodecyl sulphate in McIvaine buffer with a pH of 5. Different experimental conditions such as buffer type, pH, type and concentration of surfactants were investigated. The fluorescence intensity of the solution was recorded at 361 nm after excitation at 243 nm. The method shows linearity in the concentration range of 0.2 μg mL–1–10 μg mL–1 with a good correlation coefficient of 0.997. The relative standard deviation value was 3.62 (n = 7). The limit of detection and limit of quantification were calculated to be 2.84 × 10–3 μg mL–1 and 9.47 × 10–3 μg mL-1, respectively. The effect of excipients and co-administrated drugs was investigated and no interference was observed. The method was successfully applied for the determination of diclofenac potassium in pure form, in pharmaceutical products and in human plasma. The percentage recoveries obtained ranged from 100.25% to 102.16% for pure form and 97.50% to 102.00% for pharmaceutical products and from 98.50% to 101.67% for human plasma.
Removal of Surfactant Cetyldimethylethyl Ammonium Bromide from Water using Adsorption in Combination with a Membrane Pilot Plant
Authors: Zahoor Muhammad , Alam Sultan , Ali Muhammad , Khan Muhammad Sufaid 
Published: November 2021

Abstract
In this study, a magnetic carbon nanocomposite (MCNC) was prepared using peanut shell biomass as carbon source. The prepared adsorbent was characterised by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), thermogravimetric/differential thermal analysis (TGA/DTA) and BET surface analysis. Batch experiments were carried out to determine the adsorption parameters of cetyl dimethylethyl ammonium bromide (CDEAB) on MCNC. Of the isotherm and kinetics models used, the Langmuir model fitted the equilibrium adsorption data best, while the kinetics data were best explained by the second-order kinetic pseudo-equation. The numerical values of enthalpy change (ΔH8 = 38 kJ mol–1) and Gibb free energy (ΔG8 = 70.95 kJ mol–1, 72.19 kJ mol–1 and 73.32 kJ mol–1 corresponding to 20°C, 30°C and 40 °C, respectively) were positive, while the value of entropy change (ΔS8 = –0.11 kJ mol–1 K–1) indicated an endothermic and non-spontaneous process. After determining the optimal adsorption parameters, the adsorbent was used in a hybrid plant with a membrane pilot plant equipped with ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) membranes. In MCNC/membrane operation, an improvement in permeate flux was observed for the three selected membranes. The percentage retention of UF and NF membranes was also improved by MCNC pre-treatments in hybrid mode.

Abstract
The global community is struggling with the highly contagious COVID-19. Returning to \normal life" now poses risks, and the use of appropriate protective measures has become necessary to continue daily life and protect public health. The main protective measures to prevent transmission of COVID-19 are masks, soaps and disinfectants. Because coronavirus is a \lipid-enveloped virus", it is very sensitive to lipid-dissolving chemicals and can therefore be effectively removed by washing hands sufficiently with soap and water. However, using an alcohol-based disinfectant is a more viable option for outdoor use. Alcohol-based disinfectants are inexpensive, immediately effective, easy to use and better tolerated by the skin compared to other disinfectants. WHO recommends disinfectants containing 75% isopropanol or 80% ethanol as highly effective in inactivating the SARS-CoV-2-virus. The current review discusses the role of alcohol-based hand sanitizers (ABHS) in preventing the spread of viruses, their side effects on human health, and suggests the use of alcohol-based sanitizers as potentially effective in combating the current epidemic.
Screening of Biosurfactant Producing Bacteria Isolated from Hydrocarbon Contaminated Site and Their Potential in Biosorption of Pb(II) and Oil Biodegradation
Authors: Rastogi Swati , Ratna Sheel , Kumar Rajesh 
Published: November 2021

Abstract
In the present study, three potentially Pb(II)-resistant and biosurfactant-producing bacterial strains were isolated from a total of 23 strains using various screening methods, investigated for their biosorption of Pb(II) and used for the biodegradation of used motor oil. The results show that strain E1 (Bacillus haynesii) has significantly high efficiency in biodegradation of used motor oil, up to 82 % in the first three days. Maximum Pb(II) biosorption capacities of 238.09 mg/g and 99.01 mg/g were determined for strains E1 and F5 (Pseudomonas aeruginosa), respectively. The biosorption process was found to be in good agreement with the Langmuir isotherm for both E1 (R2 = 0.9614) and F5 (R2 = 0.9646), suggesting monolayer biosorption. The four common screening methods, namely the haemolytic assay, the determination of surface tension, the emulsifying activity and the foam test, were also correlated with the Pearson correlation method.
