Published: August 2023

INTRODUCTION Achilles tendon rupture (ATR) repair is one of the most common orthopaedic surgeries performed in the United States, however there is a paucity of literature on predisposing risk factors for hospital readmissions. The purpose of this study is to identify risk factors for 30-day readmission in patients undergoing ATR repair with emphasis on procedures performed in the outpatient setting. Specifically, we examine: 1) 30-day post-operative hospital readmission rates; 2) the medical comorbidities and patient characteristics that predisposed this cohort to post-operative complications; and 3) the complications leading to readmission.  METHODS The ACS-NSQIP was queried for patients who underwent ATR from 2015 to 2019 using CPT code 27650 in all fields yielding a sample size of 3,887 cases. The following demographic, lifestyle, and comorbidity variables were recorded: age, sex, race, BMI, morbid obesity (BMI ≥ 40.00 kg/m2), bleeding disorders, chronic obstructive pulmonary disease (COPD), diabetes mellitus, hypertension, tobacco use, and chronic steroid use. The primary outcome of 30-day readmission was defined as unplanned hospital readmission likely related to the principal procedure. Independent samples Student’s t-tests, chi-squared, and, where appropriate, Fisher’s exact tests were used in univariate analyses to identify demographic, lifestyle, and peri-operative variables related to 30-day readmission following ATR. Multivariate logistic regression modeling was subsequently performed. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated and reported. RESULTS Of the 3,887 patients included in our sample, 28 were readmitted within the 30-day post-operative period, corresponding to a readmission rate of 0.73%. Significant relationships with univariate analyses between readmission status and the following patient variables included: mean patient age (p = 0.02); hypertension (p < 0.001); BMI (p = 0.01); morbid obesity (p = 0.002); ASA Classification (p = 0.006); and bleeding disorders (p = 0.03). Multivariate logistic regression modeling confirmed that the following patient variables were associated with statistically significantly increased odds of readmission: age, p = 0.02), OR = 1.03, 95% CI [1.01, 1.06]; hypertension, p < 0.001, OR = 3.82, 95% CI [1.81, 8.06]; BMI, p = 0.01, OR = 1.06, 95% CI [1.01, 1.11]; morbid obesity, p = 0.004, OR = 3.53, 95% CI [1.49, 8.36]. CONCLUSION Our study indicated that only 0.73% of patients were readmitted after their outpatient procedure. Patients who: 1) have BMIs greater than 40; 2) are older in age 3) have hypertension; and 4) a higher ASA Classification were at increased risk for readmission.

In the era of globalization, business competition is fierce, especially in the food and beverage industry. Cincau Station, which initially only served ice cincau with palm sugar, has developed into a variety of flavors and can be accessed through a mobile application. However, this application has shortcomings in design and features that can affect consumer interest. This research uses the Customer Knowledge Management (CKM) method to analyze the UI/UX of the Cincau Station application. CKM is an approach that considers customer needs to develop ideal products. The goal of CKM is to achieve brand effectiveness and competitiveness. This research limits the analysis to the content and composition aspects of the application.

Digital humaniora og teknologi forståelse
Authors: Berthelsen Ulf Dalvad 
Published: August 2023

Der er i de senere år blevet brugt mange ressourcer på at integrere nye digitale teknologier på alle niveauer af uddannelsessystemet, både på policyniveau og i praksis. I grundskolen taler man om teknologiforståelse, i gymnasiet om informatik og på universiteterne har man efterhånden forsøgt at sætte ’computational’ foran navnene på de fleste discipliner.
Det har imidlertid vist sig at være en meget stor udfordring at implementere teknologiforståelse og computationel tænkning i skolernes, gymnasiernes og universiteternes veletablerede fag og fagforståelser (Tannert et al., 2021). Det har generelt været en udfordring inden for mange fagområder, men særligt inden for de humanistiske fag synes der at være en diskrepans mellem fagenes identiteter og etablerede fagforståelser og den nye datalogiske faglighed. Dette har resulteret i, at mange humanistiske fag har valgt at løse opgaven ved at implementere et kritisk og sociologisk orienteret perspektiv med fokus på, hvordan teknologi påvirker hverdagsliv og kommunikation (Se fx Børne- og Undervisningsministeriet, u.å.-b, u.å.-a) frem for et perspektiv, der udforsker hvordan datalogiske metoder og perspektiver kan udvide fagforståelsen.
Denne indstilling har rødder i en gammel tradition for teknologikritik inden for humaniora, der trækker på tankegods fra bl.a. Marx (1970), Horkheimer & Adorno (1969), Heidegger (1999) og forskellige poststrukturalistiske strømninger som fx actor network theory (Latour, 1999, 2005). Teknologikritikken har både været væsentlig og nødvendig, men har samtidig placeret humaniora i et modsætningsforhold til teknologi, herunder i særdeleshed digital teknologi og computationel tænkning.
I de senere år er der imidlertid, under den brede betegnelsen digital humaniora, opstået en strømning, der indtil videre først og fremmest er synlig på universiteterne, og som mere aktivt omfavner den digitale transformation. Med afsæt i et historisk rids over, hvordan den teknologikritiske position har udviklet op gennem det 20. århundrede, vil jeg i denne artikel diskutere, i hvilket omfang digital humaniora kan tilbyde en alternativ position, der gør det nemmere for de humanistiske fag dels at integrere teknologiforståelse i de eksisterende fagforståelser, dels at udvikle nye faglige identiteter som digitale humanister, for hvem avancerede digitale kompetencer og computationel tænkning indgår som en selvfølge i kompetenceprofilen.
Afslutningsvis diskuterer jeg, hvordan disse nye identiteter kan gøres tilgængelige for både elever og lærere i grundskolen og gymnasiet ved, i forlængelse af et emancipatorisk literacy-syn (Freire Paulo, 1985; The New London Group, 1996; Forfatter & Nielsen, 2021), at tage ejerskab over de nye digitale teknologier ved at tænke dem som et middel til kritik snarere end som målet for kritik.
Acute angioedema in Cape Town emergency centres and a suggested algorithm to simplify and improve management
Authors: Day C , Van der Walt J , Crombie K , Hendrikse C , Peter J 
Published: August 2023

Background. Angioedema is the most common acute allergic presentation to emergency centres (EC), with hospitalisation rates increasing in high-income countries. Angioedema can complicate with life-threatening laryngeal obstruction. There are no local data; therefore, we aimed to characterise acute angioedema cases presenting to ECs and develop a simple management algorithm.
Objective. To characterise the clinical presentation, management and outcomes of acute angioedema cases presenting to ECs. Based on these findings, we developed a management algorithm for acute angioedema to improve the care of acute angioedema in South Africa (SA).
Methods. We conducted a retrospective folder review of all patients admitted to Groote Schuur Hospital (tertiary) and Mitchells Plain District Hospital (secondary) ECs from 1 June 2018 to 31 June 2020. Using ICD-10 coding, folders of adults ≥18 years with possible angioedema presenting to the ECs were screened. An allergist extracted demographics, medical history, management and outcome data for each angioedema event.
Results. A total of 142 acute angioedema episodes were included, with a median (interquartile range) age of 42 (28 - 58) years, and 62% of patients were female. The majority (124/142, 87%) of acute angioedema EC presentations involved swelling above the shoulders, with airway involvement in 20 (14%) patients, with two patients requiring intubation. Nineteen (13%) patients required admission, with five (26%) admitted to high care/intensive care. Drug-induced angioedema was the most common cause, with 64/142 (45%) linked to a known offending drug, 42/64 (65.6%) being angiotensin-converting enzyme inhibitor (ACE-I). Critical information to guide angioedema management, including past personal/family allergy history, and duration of angioedema prior to EC visit, was not recorded in 64.7% and 37.8% of EC records, respectively. Unnecessary treatment with corticosteroids or antihistamines occurred in 19/53 (36%) and 16/53 (30%) cases with bradykinin-mediated angioedema ACE-I angioedema and hereditary angioedema). Overall, only 36/142 (25%) of angioedema patients were connected to allergy care.
Conclusion. Angioedema is the most common allergy presentation to two ECs in Cape Town, SA. Bradykinin-mediated angioedema secondary to ACE-I therapy is the single most common offender, and was not appropriately managed in more than a third of cases. Based on these findings, we have developed a management algorithm that easily stratifies patients into bradykinin or mast cell-mediated angioedema with a step-by-step management approach that is applicable to the SA context. Ongoing awareness and education on allergy emergencies are required to ensure accurate diagnosis of less common causes of angioedema (particularly bradykinin-mediated angioedema) and linkage to allergy specialist care.
First Palaeozoic Phyllocarid Crustaceans and Pterygotid Eurypterids in Serbia
Authors: Radonjić Miloš , Sachanski Valeri 
Published: August 2023

Palaeozoic phyllocarid crustaceans and pterygotid eurypterids from the Gethicum Zone of Carpatho-Balkanides in Serbia are herein documented for the first time. The described and illustrated phyllocarid remains consisting of a coupled telson and furcal rami were collected from upper Silurian (?) shale. This specimen is fragmented and poorly preserved to allow identification to species level, and has thus been assigned to Ceratiocaris sp. indet. The eurypterids are represented by part of a fragment, showcasing the distinct scale-like ornamentation of the pterygotids, and a segment of a walking leg. The pterygotid remains were found together with a few graptolite taxa (Monograptus sudeticus Porębska, “M.” microdon microdon Reinh. Richter, Neomonograptus aequabilis (Přibyl), Uncinatograptus hercynicus (Perner), U. subhercynicus (Willefert)), which are characteristic for the lower part of the U. hercynicus graptolite zone (Lochkovian, Lower Devonian). There are at least two species in this stratigraphic interval that correspond to the pterygotid eurypterids remains from Serbia – Acutiramis perneri Chlupáč and Pterygotus cf. barrandei Semper, but without the chelicerae, it is impossible to make precise identification. These new finds from eastern Serbia, together with the Bulgarian ones, are a further confirmation of peri-Gondwanan origin of pre-Variscan Palaeozoic sediments in the West Srednogorie Unit in Bulgaria and in the Gethicum Unit in Serbia.

Published: August 2023

In modern communication system, mobile communication spectrum, below 3 GHz bands, faces more shortage and is not able to serve people with more efficient device connectivity and required data speed. Upon this background, 5G wireless communication – the 5th generation mobile technology standards are able to deliver high data rates, low latency communications, and massive device connectivity. For the efficient deployment of the 5G systems, and in order to support higher bandwidth, there is a dire need to design a compact and efficient antenna at mm wave frequencies (26/28 and 38). The resulting antenna, as the outcome, has been established to possess a compact size of 10 × 12 × 0.254 mm3 that covers three bands from the frequency spectra. The lower band resonant frequency is located at 26.74 GHz, the range between 25.44 GHz and 28.37 GHz, the middle band resonant frequency is located at 32 GHz, the range between of 31.08 GHz and 32.48 GHz, and the higher resonant frequency is located at 38.76 GHz, the range between 36.04 GHz and 40.34 GHz. In this article a modified novel structure of partial ground plane and DRA are used to get the better radiation enhancement and circular polarization. In this, the circularly polarized bands consist of the axial ratios <3 dB which are 27.95 GHz to 28.37 GHz, 31.08 GHz to 31.67 GHz, and 36.04 GHz to 38.73 GHz. The gain achieved is greater than 6.5 dBi and the efficiency is greater than 96% over the three bands. Ultimately, it is proved to the right option for 5G mm wave applications.

Published: August 2023

This work investigates the effects of circUBR1 and the underlying mechanisms on the growth, migration and penetration of HSC3 cells derived from oral squamous carcinoma. The expression levels of circUBR1, miR-216a-3p and HSC3 were assessed in tissues from oral squamous cell carcinoma (OSCC) and adjacent tissues.
Based on the transfection targets, the cells were divided into four groups: si-NC, si-circUBR1, miR-NC, miR-216a-3p, si-circUBR1+anti-miR-NC and si-circUBR1+anti-miR-216a-3p. The cell viability, scratch healing rate, MMP-2 and MMP-9 expression, number of cell clones formed, and number of invasion cells were significantly lower in the miR-216a-3p group compared to the miR-NC group (p<0.05).
Moreover, when comparing the si-circUBR1+anti-miR-NC group to the si-circUBR1+anti-miR-216a-3p group, the cell viability, scratch healing rate, MMP-2 and MMP-9 expression, number of cell clones formed, and number of invasion cells were significantly higher in the si-circUBR1+anti-miR-216a-3p group (p<0.05). This suggests that disrupting circUBR1 expression leads to up-regulation of miR-216a-3p, resulting in reduced proliferation, clone formation, migration, and invasion of OSCC cells.

Published: August 2023

AbstractBiological organisms can pose a threat to water quality and can be responsible for waterborne diseases. Because it is very expensive and time consuming to test for each pathogenic organism, coliform bacteria and E. coli, which originate in environmental and animal sources, serve as good pathogenic indicator organisms. This study focused on evaluation of water quality in New Jersey water bodies by monitoring both E. coli and coliform using different methods. Water samples were taken over two months at different sites. Three different methods used in this study are membrane filtration, PetrifilmTM and IDEXX methods to compare and determine which one or in combination methods are the most efficient and reliable way to identify and quantify bacterial contamination. It was concluded that areas that were highly urbanized, specifically high urban and agriculturally developed areas, had an increased level of contamination. Our study suggested that modified membrane filter method in combination of IDEXX Colilert® System provide the best results. Further research, such as Microbial Source Tracking (MST), will be conducted to identify the origin of fecal contamination.
Dynamic Characteristics of Periodic Motions in a Restricted N-Body Problem
Authors: Tsironis Christos S. 
Published: August 2023

AbstractWe investigate the existence and follow the evolution and dynamic stability of periodic motions in a restricted version of the N-body problem, where the positions of the mass bodies reside persistently on a planar polygon ring and its geometrical centre. The results show the existence of both (linearly) stable and unstable periodic orbits around the body placed on the ring centre (inside the ring), around all the periphery bodies (outside the ring) and around one or more of the periphery bodies. The stable periodic trajectories form regions of gravitational stability, whereas some classes of the unstable orbits exhibit bifurcations to non-symmetric periodic orbits of the same period, and less often period-doubling bifurcations.

Authors: Tulin Anabella B. , Ranises Mechelle , Galambao Marciana B. , Umar Mohammed , Dorahy Chris G. 
Published: August 2023

AbstractA double pot technique experiment was conducted to determine the nutrient supplying capacity of five acid soils planted with three vegetables such as cabbage (Brassica oleracea), maize (Zea mays) and tomato (Solanum lycopersicum L.). The soils used in the study were taken from Kibangay, Bukidnon; Mapayag, Bukidnon; Kapatagan, Davao del Sur; Claveria, Misamis Oriental and Cabintan, Leyte representing the acid soils of southern Philippines planted to vegetables. Results of the nutrient omission trials showed that the three vegetables tested have varying responses to five different soils as affected by nutrient availability. In most soils, regardless of vegetable planted, nitrogen (N) availability was the most critical nutrient affecting vegetable production followed by phosphorus (P) in the case of Cabintan and potassium (K) for Mapayag, Kibangay, Kapatagan and Claveria, respectively. This valuable diagnostic tool offers a cheap and simple method of assessing the nutrient supplying capacity of the various soils tested.
Treatment of High Strength Vegetable Processing Wastewater with a Sequencing Batch Reactor
Authors: Lam Ka Yee , Zytner Richard G. , Chang Sheng 
Published: August 2023

AbstractThe feasibility of an aerobic sequencing batch reactor was studied at the lab scale to treat the high organic loading present in two vegetable processing wastewaters. Hydraulic retention time (HRT) was varied to evaluate its effect on the removal efficiency of chemical oxygen demand (COD), total Kjeldahl nitrogen (TKN) and total phosphorus (TP). The results showed that a longer HRT promoted the removal of TP, while the liquid drawn per cycle had a larger effect on the COD removal efficiency. An increase in the COD/TKN and TKN/TP ratio decreased the removal efficiency of TKN and TP respectively. The optimized configuration was able to reduce the wastewater loadings to acceptable sewer discharge limits, making it possible eliminate the sewer surcharge fees.
Energy-Saving Periodic Flight at Transonic Speeds
Authors: Amouyal G. , Weihs D. 
Published: August 2023

AbstractWe examine possible energy saving by periodic changes in speed and altitude relative to steady state cruise, in the transonic regime. We develop a theoretical model of two-phase periodic flight with altitude variation in the transonic regime and compare it with a steady horizontal flight at the same average speed. The model predictions are verified by wind tunnel experiments. For example, by periodically accelerating from M=0.7 to M=1.1 while losing altitude, and then climbing back to the original height while decelerating, one can achieve savings of about 20% relative to steady flight at the same average speed and constant altitude.

Background
Dugongs are marine mammals with a crescent-shaped tail fluke and a concave trailing margin that belong to the family Dugongidae., They are distributed widely in the warm coastal waters of the Indo-Pacific region. Importantly, the population of dugongs has decreased over the past decades as they have been classified as rare marine mammals. Previous studies have investigated the habitat and genetic diversity of dugongs. However, a comprehensive histological investigation of their tissue has not yet been conducted. This study provides unique insight into the organs of dugongs and compares them with other mammal species.

Methods
Tissue sections were stained with Harris’s hematoxylin and eosin Y. The histological structure of 17 organ tissues obtained from eight systems was included in this study. Tissue sections were obtained from the urinary system (kidney), muscular system (striated skeletal muscle and smooth muscle), cardiovascular system (cardiac muscle (ventricle), coronary artery, and coronary vein), respiratory system (trachea and lung), gastrointestinal system (esophagus, stomach, small intestine, liver, and pancreas), reproductive system (testis), lymphatic system (spleen and thymus), and endocrine system (pancreas).

Results
While most structures were similar to those of other mammal species, there were some differences in the tissue sections of dugongs when compared with other mammalian species and manatees. These include the kidneys of dugongs, which were non-lobular and had a smooth, elongated exterior resulting in a long medullary crest, whereas the dugong pyloric epithelium did not have overlying stratified squamous cells and was noticably different from the Florida manatee.

Discussion
Histological information obtained from various organs of the dugong can serve as an essential foundation of basal data for future microanatomical studies. This information can also be used as high-value data in the diagnosis and pathogenesis of sick dugongs or those with an unknown cause of death.
