Reachable Set Computation with Terminal Velocity Constraints
Authors: Natherson Robyn A. , Scheeres Daniel J.
Published: September 2024

This work establishes a general-purpose method for computing the exact boundary of the reachable set in a specified direction, with additional constraints imposed on the terminal velocities. Reachable sets with rest boundary conditions, that is, zero-velocity constraints imposed at initial and final times, are of interest for formation flying and spacecraft rendezvous and docking applications. The rest-to-rest reachability problem is extended to compute reachable neighboring circular orbits and a modified problem formulation is developed to exclusively compute the maximum and minimum reachable circular orbits. Reachable sets are computed by applying classical optimal control techniques to a maximum position optimization problem. A solution method for the optimization problem is outlined, which makes use of a Newton’s method solving schema. Additional constraints are added to the problem to compute maxima along specified directions, allowing for the characterization of the reachable set in as many directions as desired. Example reachable sets are computed to illustrate the use of this method on various systems, including an application to relative motion.
Role of tele-physical therapy in quality of life and satisfaction among patients with musculoskeletal disorders
Authors: Arwa Munaza , Chaikumarn Montakarn
Published: September 2024

Objectives:

Previous research has shown telephysical therapy to be highly efficient, but it has shown vague results in terms of quality of life and satisfaction improvement in patients with musculoskeletal disorders (MSD). Hence, this study aimed to find the role of telephysical therapy in improving the quality of life of patients with MSD.

Methods:

The study was conducted using a pre- and post-study design, enrolling 327 patients with MSDs who contacted Marham for online physical therapy consultations. Participants filled out telehealth usability and European quality of life-5 dimensions questionnaires (EQ-5D-5L) in the priory. After tele-sessions, they were again requested to fill out questionnaires along with complete questionnaires and ten open-ended questions about their telephysical therapy experience. Any participant with cognitive dysfunction or inability to complete prescribed tele-sessions was excluded from the study.

Results:

Participants had a mean age of 41.80 (±14.84) years. One hundred and fifty-three were male and 174 were female. Thirty-nine distinct MSDs were diagnosed, with low back pain being the most prevalent among the participants. The Marham’s therapists prescribed a minimum of 3 and a maximum of 12 tele-sessions. The paired sample t-test showed statistically significant differences between pre- and post-scores of telehealth usability and EQ-5D-5L (P < 0.001). According to multiple regression analysis, age, sex, and number of sessions were the most influencing variables, with a 35% variance in quality of life and 35.4% in satisfaction. Most participants, that is, 83% reported excellent experiences.

Conclusion:

The study concluded that telephysical therapy plays a positive role in improving the quality of life and satisfaction of MSD patients.

Authors: Sallam Masoud Ahmed M. , El Zaher El Zaher H. , Nada Abdelrahman N. , Nagy Amr M. , Moussa Islam S.
Published: September 2024

Objectives:

The objective of this study was to compare the Ilioinguinal approach and the modified Stoppa approach regarding clinical and radiological outcomes.

Methods:

This prospective randomized controlled study involved 30 patients who were split into two groups.

Results:

There was no significant difference regarding the clinical and radiological outcomes and residual medial wall displacement. Blood loss during the operation was less in the modified Stoppa approach.

Conclusion:

When treating anterior column fractures, the modified Stoppa approach reduces blood loss and expedites surgery compared to the Ilioinguinal approach. The study’s original hypothesis has been validated, indicating that the modified Stoppa approach is a superior alternative for managing these fractures.
Bibliometric Analysis of Publications on the Theory and Practice of LBC Application
Authors: Volkova Natalia A. , Pivovarova Marina A.
Published: September 2024

The relevance of bibliometric analysis of publications on the application of the Library and Bibliographic Classification (LBC) is due to the scale and pace of fundamental transformations in Russia. At the end of the 20th century the practice of bibliographic reflection of the documentary flow on the issues of the Soviet LBC was broken. In 1990 a retrospective scientific and auxiliary index of works on a wide range of LBC-related problems published in our country and abroad was published for the last time. For more than thirty years the needs for completeness of information and bibliographic support of specialists engaged in the development, study and implementation of the LBC have significantly increased. The gradual obsolescence of any library classification used for systematization of the colossal document flow has caused the increased scientific interest in the development of the concept of a new edition of the LBC Medium Schedules.

The purpose of bibliometric analysis of publications on LBC issues is to determine the directions of scientific research of this problematic. To achieve this goal, a scientific and auxiliary index on LBC was formed, which included 219 publications (from 2001 to 2023 editions). The search was carried out using the keywords “Library and Bibliographic Classification” and “LBC” on the electronic resources of the Russian State Library, in the scientific electronic library elibrary.ru, on the official websites of Russian libraries of different subordination, on the portal of the International Society for Knowledge Organization (ISKO). The object of analysis is the flow of publications on the theory and practice of this classification system.

The instrumental apparatus includes both general scientific and special methods of quantitative and qualitative study of flows of scientific and information documents.

Bibliometric analysis of publications on the theory and practice of LBC application allowed us to identify the main directions of scientific research in this problem area.

Published: September 2024

CO hydrogenation is a promising approach for the storage of renewable energy in the form of hydrocarbons via the Fischer-Tropsch synthesis (FTS). Since transient operation of FTS reactors might be necessary and even be beneficial, transient kinetics for a rational catalyst and reactor design are essential. In order to advance the development of such transient kinetics, the periodic transient kinetics (PTK) method was applied to the CO hydrogenation on a Co/TiO2 catalyst under FT-like conditions. It was revealed that there are two carbon species of different reactivity, Cα and Cβ, present on the catalyst surface during the reaction. Cα forms fast within a few seconds and is highly reactive, while Cβ forms slowly, is accumulating on the surface over a longer time and imposes an inhibiting effect. However, a contribution of Cβ to the chain growth reaction was shown. Finally, the transient experimental results are evaluated based on a material balance and the amounts of Cα and Cβ present on the catalyst surface during the reaction were determined.
Nano-phase separation and analyte binding in a SARS-CoV-2 biosensor investigated by nano-IR spectroscopy

Published: September 2024

Biosensors based on DNA aptamers are increasingly used in diagnostic applications. To improve the sensitivity and specificity of aptasensors, parameters affecting the stability and binding efficiency of the receptor layer need to be identified and studied. For example, the influence of blocking, i.e. the addition of inert molecules to the receptor layer, on sensor performance is well accepted, but its effects on the nano-structure have not been studied in detail. Phenomena such as phase separation into nanodomains have been reported, but their effect on analyte binding remains uncertain. Here, nano-IR spectroscopy is used together with complementary macroscopic spectroscopic methods to study the nano-structural variations during the fabrication of an aptasensor consisting of a mixed self-assembled monolayer (SAM) of sensing aptamers and inert polyethylene glycol. The investigated sensor was recently developed and optimized for the detection of the spike protein of the omega variant of SARS-CoV-2. The initially formed aptamer layer is homogeneous and flat compared to the length of the DNA. In contrast, the film after blocking is much thicker and phase separated into nanodomains consisting of an aptamer-rich and a slightly thicker PEG-rich phase. The unambiguous chemical identification of the nanodomains is achieved by analysis of nano-IR spectra and nano-IR imaging. Furthermore, the analyte bound to the receptor layer was detected at the single molecule level. The detailed analysis of the local nano-IR spectra further revealed chemical properties such as the amorphous state of the PEG molecules within the nanodomains and a strong change in the secondary structure of the analyte. This study significantly advances our understanding of the chemical processes in the receptor layer of biosensors at the nanoscale.
An Adaptable Blueprint for Non-Metal Near-Infrared Organic Photo-catalysts by Aromatic Sulfones
Authors: Yoshida Kazuya , Suzuki Toshiaki , Biju Vasudevanpillai , Takano Yuta
Published: September 2024

We present a versatile approach for designing and utilizing high-performance near-infrared (NIR) organic photo-catalysts based on aromatic sulfones. Our sulfone-rosamine-based photo-catalyst 3 demonstrates exceptional capabilities, including high photo-oxidation ability for metal-free photo-oxidative bromination, intrinsically oxygen-independent redox reactions, and remarkable photo-stability with a turnover number (TON) exceeding 2800. We showcase the photo-catalyst's efficacy in photo-oxidative bromination of aromatic compounds under 738 nm illumination. The reaction mechanism is elucidated through a combination of electrochemical studies, time-resolved spectral measurements, and DFT calculations. Transient absorption measurements using the randomly interleaved pulse train (RIPT) method reveal the photo-excited state of 3 approximately 1 ns post-excitation, demonstrating electron transfer from the substrate to excited 3 as the initial step. 3 demonstrated its photocatalytic ability for several aromatic substances, including those that exhibit strong light absorption below 500 nm, which overlaps with the absorption of certain conventional organic photo-catalysts. This aromatic sulfone-based approach offers a robust blueprint for developing NIR organic non-metal photo-catalysts with superior photo-oxidation ability and stability, addressing key limitations of conventional organic NIR-photocatalysts.

Ciliated Hepatic Cyst: Report of a Case and Review of the Literature
Authors: Jaime Mejías-Bielsa , Beatriz Agredano-Ávila , Eva Vázquez Tarrio , Ana Teijo-Quintáns
Published: September 2024

The ciliated hepatic cyst of the anterior intestine is a less frequent benign entity that arises from the alteration in the migration of embryological remains. Most of them are found in the left lobe of the liver, especially in segment IV. Its wall is covered by a pseudostratified ciliated columnar epithelium, a layer of connective tissue, smooth muscle, and a surrounding fibrous outer layer. We present the case of a 61-year-old man who, in the context of a scheduled admission for drainage of an intraabdominal abscess, was incidentally discovered to have a hepatic lesion of cystic aspect. The anatomopathological diagnosis was that of a ciliated hepatic cyst. Due to its low frequency in clinical practice (in part due to its incidental character), a review of the case and a review in the literature of the peculiarities of said entity are proposed.
Non-surgical Treatment of Verrucous Hyperplasia on Amputation Stump: A Case Report and Literature Review
Authors: Sajeda Alnabelsi , Reem Hasan , Hussein Abdallah , Suzan Qattini
Published: September 2024

Verrucous hyperplasia is a wart-like lesion that can develop on amputation stumps, often due to poor-fitting prostheses, venous stasis, friction, and bacterial infections. While surgical excision is sometimes necessary for intractable cases, many instances can be managed non-surgically. We present the case of a 35-year-old male with a slowly growing verrucous plaque on his amputated stump that had caused repeated infections. His prosthesis was loose, allowing the stump to hang loosely inside the socket. After histological confirmation of verrucous hyperplasia, he was advised to change his prosthesis and use compression bandaging. Over 5 months, the lesion resolved without surgery. Early recognition and non-surgical management, including proper prosthetic fit, compression, and hygiene, can often successfully treat verrucous hyperplasia of amputation stumps. This avoids the need for excision in many cases. Patients and clinicians should be aware of this condition and the importance of prosthetic fit and limb care to prevent and treat it.
DO LATENT TUBERCULOSIS AND AGE IMPACT THE POST-COVID-19 EXPERIENCE?
Authors: KANMAZ Zehra Dilek , MANDAL ZİREK Tuğba , ARAS Gülfidan , TUNCAY Esin
Published: September 2024

Background: There is not enough information about the long-term effects of COVID-19 infection in those who have recovered. According to epidemiological studies, COVID-19 progresses less severely in countries where the Bacillus Calmette-Guerin vaccine is regularly applied than in those where it is not. The purified protein derivative of tuberculin is an indicator of the Bacillus Calmette-Guerin vaccine’s protective effectiveness against latent tuberculosis. In our study, we aimed to investigate the relationship between latent tuberculosisand the permanent effects of COVID-19.Our objective was to analyze the long-term relationship between latent tuberculosisand COVID-19. Materials and Method: We included all clinical, laboratory, and radiological baseline data of patients who were hospitalised for COVID-19 pneumonia between 2020 and 2021 during the pandemic in our study and compared them with data from six months later. Results: Although there was no statistically significant correlation between purified protein derivative of tuberculin positivity and the long-term effects of COVID-19 (p = 0.084), age exhibited a statistically significant relationship with the presence of post-COVID-19 sequelae (p = 0.004). Patients with chronic pulmonary disease displayed a significantly greater percentage of symptoms (p=0.005). Conclusion: We could not find any relationship between purified protein derivative of -tuberculin latent tuberculosis infection and long COVID-19 symptoms. We observed sequelae lesions more frequently in the follow-up of elderly patients. Post-COVID-19 symptoms were more common in patients with chronic lung disease. Thus, it is recommended to prioritise radiological and clinical follow-up in elderly patients and those with chronic lung conditions.

Published: September 2024

Introduction: The aging population is one of the main reasons for the increase in stroke cases.The aim of this study was to evaluate the predictors of 3-month outcomes in patients aged ≥65 years who underwent mechanical thrombectomy for acute ischemic stroke and compare patients aged 65–79 years with those aged ≥80 years in terms of demographic characteristics, workflow, functional outcomes, and complication rates. Materials and Method: This retrospective cohort study included 169 consecutive patients aged ≥65 years who underwent mechanical thrombectomy for acute ischemic stroke due to large vessel occlusion between April 2020 and May 2023. Results: Recanalization was successful for 148 (87.57%) patients.According to multivariable logistic regression analysis results, low (≤9) Alberta Stroke Program Early Computed Tomography score (odds ratio: 4.217, 95% confidence interval: 1.209–14.715, and p=0.024), high National Institutes of Health Stroke Scale score at 24th hour (odds ratio: 1.192, 95% confidence interval: 1.087–1.306, and p<0.001), high Acute Physiology and Chronic Health Evaluation score (odds ratio: 1.127, 95% confidence interval: 1.016–1.250, and p=0.023), and intubation need (odds ratio: 15.055, 95% confidence interval: 2.087–108.612, and p=0.007) were independent predictors of poor outcome. Conclusion: The lack of significant differences in workflow, functional outcomes, and complications among patients ˃80 years of age indicates that MT is effective in this age group. Considering the aging population, identifying the predictors of 3-month outcomes after mechanical thrombectomy will help predict outcomes, better identify elderly patients who may benefit from the procedure, and guide treatment decisions.

Introduction:Falls are a major cause of mobility and mortality among older adults. Regional monitoring and analysis of the risks and outcomes associated with falls are important for developing preventive approaches. Materials and Method: This cross-sectional analysis retrospectively reviewed the electronic medical records of older adults (aged ≥65 years) who presented to the emergency department of a university hospital in Izmir, Turkey between January 2019 and January 2020. Information regarding pre-fall, fall-related, and post-fall treatments was analyzed. Results: Over one year, 2,037 older patients (68.4% [n=1,349] women, with a mean age of 80.65+7.50 years) presented to the emergency department because of falls. Unfortunately, many important pieces of fall-related data were not routinely recorded at the institution. According to the available records, the majority of the patients were physically active (84.4%), lived independently (53.6%), and most frequently fell as a result of tripping or stumbling (88.1%). Of the patients, 74.9% were discharged; however, no information was available regarding whether they were informed about fall prevention before discharge. Head trauma was the most common cause of admission (n=415), and hip fractures were the leading surgical causes (n=175). The presence of chronic disease (p=0.910), age (p=0.274), and sex (p=0.304) did not affect the risk of fractures after falling. Conclusion: Fall prevention is a more feasible and efficacious strategy than addressing the resultant complications. The current practice of analyzing the fall risks of individuals who present to emergency departmentwith falls and directing them to preventive programs is insufficient to address this issue.

Academic Group Discussions as a Ritual Frame: An Interactional Approach
Authors: Pan Zhaoyi
Published: September 2024

Academic group discussions were studied as a ritual frame by adopting the interactional approach in this research. The first aim was to examine how students reached alignment with university lecturers via speech acts (SAs) in group discussions based on the integrative SA model in the interactional approach. The second aim was to examine how the students avoided conflicts with university lecturers in the process of reaching alignment. A total of 61 Thai university students and two American university lecturers were involved in this research. The data consisted of naturally occurring group discussions: English was used as a lingua franca (ELF). Qualitative and quantitative methods were used for the analyses in this research. Following the interactional approach, a bottom-up analysis was employed to identify the SAs. The results revealed seven Exchange patterns that consisted of different Moves realized via the SAs in the academic group discussions, including the frequent uses of the SAs Request, Opine, Tell, and Resolve. The Exchange patterns indicated that academic group discussions constituted a ritual frame in which the seemingly erratic utterances had regular patterns. Furthermore, the students did not engage in conflicts with the lecturers due to the SAs Request, Resolve, and Opine including a Grounder. This finding indicated that the disagreements in the academic group discussions were regarded as having positive discourse functions for resolving academic problems.

The activity concentrations of natural radionuclides in drinking water may be enhanced depending on the geological strata from which it is extracted. The demand and consumption of bottled drinking water is increasing every year in Uganda mainly in Kampala city. Therefore, the study was purposed to assess the levels of natural radioactivity using a gamma spectrometer in commonly bottled drinking water in Kampala City. The mean specific activities for Ra-226, Th-232, and K-40 in bottled drinking water were 4.45±0.20, 1.32±0.27, and 46.33±0.24 Bq/l respectively which exceeded the specific World Health Organization recommended guidance level of 1.0 Bq/l except for K-40. The mean activity concentrations were however comparable to the mean concentration of tap water used in Kampala City, that is 4.00±0.16, 1.4±0.19, and 47.05±0.21 Bq/l for Ra-226, Th-232, and K-40 respectively. The annual effective dose contributed by two radionuclides of Ra-226 and Th-232 in the bottled water exceeded the maximum dose limit of 0.1 mSv/y recommended by the World Health Organization (WHO). The mean estimated excess lifetime cancer risk due to Ra-226 (0.00177) exceeded the recommended limit of 0.001 while that due to Th-232 (0.0001) was below the recommended limit. Therefore, the main contributor to the total annual ingestion dose was Ra-226. Due to the high solubility and toxicity of Ra-226, there is a significant concern warranting further investigation. Finally, the results from the study revealed that there was not any trace of contamination from artificial radionuclides in the bottled drinking water manufactured and consumed within Kampala City. With the growing populational demand for bottled drinking water, it's recommended that radioactivity levels comply with the WHO recommended radioactivity levels. Therefore, this study contributes to the revision of standards and development of regulations for radiological protection of the public and the environment from risks of radiation exposure associated with bottled drinking water.
Environmental Levels of PCDD/Fs near Cement Plants in Catalonia, Spain. An Update of Human Health Risks

Published: September 2024

Cement production is an important industrial activity that generates large amounts of pollutants, including, among others, polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs). These environmental contaminants are persistent and bioaccumulative, potentially causing serious adverse effects on human health, including cancer. The present paper was aimed at providing an update of the environmental concentrations of PCDD/Fs around various cement plants located in Catalonia, Spain. The non-carcinogenic and the carcinogenic risks associated to PCDD/Fs exposure were also assessed for the population living near the facilities. According to the present results, the environmental burdens of PCDD/Fs were highly dependent on the surroundings, rather than the technical specifics characteristics of each facility. Thus, higher concentrations were found near cement plants located in urban areas, where other emission sources (e.g., heavy traffic, domestic heating, etc.) may be present. The surveillance studies showed long-term stable concentrations in air, while PCDD/Fs levels in soil and vegetation were more variable. Although inhalation was the most relevant pathway of environmental exposure, the main uptake of PCDD/Fs occurs -in general- via dietary intake. Cancer risks were higher for people living near cement plants in urban areas than in rural environments, but at levels that are considered as acceptable by international regulations. In turn, the non-carcinogenic risks suggest a low concern, as the hazard quotient was <1. Long-term surveys conducted in Catalan cement plants indicate that these facilities, which are periodically (every two years) monitored, should not be of concern for human health, in terms of PCDD/F exposure.

The globalization of capital markets has accelerated capital movements, turning the world into one large marketplace. International trade has become an important tool in shaping the financial structure of countries. However, elements such as customs duties and import quotas play a decisive role in trade between countries. Taxes, which are a financial policy tool of countries, are used to influence foreign trade, particularly imports. One of the determining factors in foreign trade activities is the exchange rate. The purpose of this study is to examine the effect of taxes on imports and the change in the nominal exchange rate on the import volume of goods and services. In this study, which examined 20 Organization for Economic Co-Operation and Development (OECD) countries with data for the period 1999-2021 taken from the World Bank official website, the model was analyzed with the help of AR (1) Residual Random Effects Generalized Least Squares Regression Model Estimator. The analysis revealed that increases in international trade taxes and exchange rate increases reduce the import volume. This result empirically supports the conclusion that taxes on international trade and reductions in exchange rates increase import volume.

Uluslararası deniz taşımacılığının başlıca unsurları depolar, limanlar, ticari yük gemileri ve bu gemilerde çalışan denizcilerdir. Denizcilerin hem yaşam hem de çalışma alanı olan ticari yük gemileri izole, hareketli, riskli, gürültülü, erkek egemen ve hiyerarşik mekânlardır. Denizcilerin çalıştıkları gemi türleri her sözleşmede değişebilse de iş sözleşmelerinin belirli süreli olması ve hiyerarşideki konumlarına göre gemide üstlendikleri görevler genellikle değişmeden kalmaktadır. Etnografik yönteme dayanan ve çalışma ilişkilerinin temel unsurlarından olan ücretler ve güvencesizlik olgularını uluslararası taşımacılık yapan dökme yük gemilerinde çalışan denizciler üzerinden analiz etmeyi amaçlayan bu araştırmadaki temel hareket noktası deniz taşımacılığının ekonomi politiğidir. Ekonomi politik bir perspektiften etnografik yöntemle elde edilen bulguların değerlendirildiği bu araştırmada, ücretler ve güvencesizlik olguları üzerinden simsarların bu özel işgücü piyasasındaki fonksiyonlarına, iş arama sürecinin metalaşmasına, aynı hiyerarşik konumdaki denizciler arasındaki ücret farklılıklarının temellerine ve son olarak denizcilerin güvencesizliğe karşı direniş taktiklerine yoğunlaşılmaktadır.
