Authors: Asware Arati Dattatray , Kaur Pawanpreet , Parmar Anupama , Chopra Harish Kumar 
Published: September 2024

AbstractMagnetic ionic liquids (MILs) are a subclass of ionic liquids that exhibit paramagnetic properties intrinsically, without the need for additional magnetic particles. These properties can be attributed to the cations, anions, or both. Typically, MILs incorporate transition or inner‐transition metals within the anion structure. These adaptable liquids demonstrate remarkable physicochemical properties, notably a robust response to external magnetic fields. The body of research concerning the synthesis, characterization, and practical applications of MILs has expanded swiftly in recent times. This review delves into the latest research on the synthesis, properties, and utilization of MILs across various domains, including catalysis, fluid‐fluid separation, polymer science, and analytical chemistry. Within the realm of analytical chemistry, MILs are pivotal, serving as solvents in various analytical procedures such as dispersive liquid‐liquid micro‐extraction, matrix solid‐phase dispersion, and single‐drop micro‐extraction. Owing to their paramagnetic nature, MILs are instrumental in the separation process, streamlining organic reactions by obviating the need for traditional extraction or centrifugation steps.

Published: September 2024

AbstractCatalytic transfer hydrogenation of levulinic acid (LA) to γ‐valerolactone (GVL) was attractive in biomass conversions since GVL is highly useful in different applications, such as polymer synthesis, fuel, and food. Various catalytic systems were reported for the reaction, yet harsh reaction conditions were generally required, which could restrict the scaling up of the reaction. Herein, we developed an effective and green bi‐solvent system of isopropanol/water for the catalytic transfer hydrogenation of LA to GVL over a ruthenium–phosphorous carbon (Ru‐PC) catalyst. It was found that the presence of water in the solvent system promoted the production of GVL from LA. The effect of isopropanol/water ratios and other reaction conditions were investigated, exhibiting that 93.8% yield of GVL was achieved using isopropanol/water ratio of 2.5:2.5 at 140 °C for 4 h and over Ru‐PC catalyst. Combining water and organic solvent not only reduced the usage of organic solvent but also created an effective bi‐solvent system for catalytic reactions.

Published: September 2024

AbstractAccording to the International Diabetes Federation, the global prevalence of diabetes is projected to increase to 643 million individuals by 2030 and 783 million by 2045. DPP 4 inhibitors approved by regulatory authorities worldwide, efficiently to regulate high blood sugar levels by impeding the degradation of glucagon like peptide‐1 (GLP‐1), an incretin hormone, prolonging the physiological effects of GLP‐1. In the present research work, a total of 12 glycinamide‐based compounds with aromatic substituents on the N‐terminus and heterocycles like piperidine, 4‐phenylpiperazine, and 6‐fluorobenzo[d]isoxazol‐3‐piperidine on the C‐terminus were synthesized and characterized. The synthesized compounds were subjected to in vitro DPP 4 inhibition assay. The promising compound JAG‐D2 was evaluated in vivo using OGTT assay in streptozotocin‐induced diabetic rats. JAG‐D2 produced a significant reduction in blood glucose levels at 20 mg/kg and 40 mg/kg doses when compared with a 1 mg/kg dose of the reference standard sitagliptin. The synthesized compounds occupied the active site of DPP 4 as demonstrated in molecular docking and MM‐GBSA analysis for rescoring on the basis of binding free energy. Molecular dynamics studies displayed the stability of the docked pose of JAG‐D2 in the catalytic site of DPP 4. All compounds exhibited compliance with Lipinski's rule of five, suggesting drug‐like properties.

AbstractWith the development of new science and technology, more and more strategic emerging industries have grown up close to the development of science and technology. Companies in these industries no longer emphasize the unilateral loyalty and commitment of employees to the organization but focus on building mutual loyalty and trust between the organizations and employees. Based on the leadership‐member exchange theory and organizational support theory, the study establishes a model of the influence mechanism of narcissistic leadership on organizational support and puts forward hypotheses. Using the questionnaire survey method, from the eight major fields involved in high and new technologies: electronic information, biology and new medicine, aerospace, new materials, high‐tech services, new energy and energy saving, resources and environment, advanced manufacturing and automation, and conducts empirical research on the 228 valid questionnaires recovered in a group manner. The relationship between narcissistic leadership and organizational support is explored at different power distance levels. Empirical results show that at low power distances, narcissistic leadership is negatively correlated with leadership identification. At high power shifts, narcissistic leadership is positively correlated with leadership identification. Regardless of the level of power distance, leadership identification will positively affect organizational support, and leadership identification mediates the relationship between narcissistic leadership and organizational support. This study has contributed to the study of narcissistic leadership and organizational support and has given relevant recommendations in combination with management practices. This study can help to understand the internal operation mode of the organization and provide theoretical support for system science. Besides, it guides the development of intelligent systems to evaluate the impact of leaders' behaviours accurately.
Life Cycle Assessment of Additively Manufactured Foundations for Ultratall Wind Turbine Towers
Authors: Jones Kathryn E. S. , Li Mo 
Published: September 2024

ABSTRACTWind energy production is rapidly growing in the United States and is expected to continue increasing as more and larger wind turbines are installed. To support these taller and heavier onshore turbines, new foundations must be designed and manufactured. One proposed method of reducing the total amount of concrete and steel in spread foundations is to utilize additive manufacturing to enable more material‐efficient designs. To compare these additively manufacturing‐enabled designs to conventional foundation designs, this study performs a life cycle impact assessment of four ultra‐tall wind turbine foundations: two foundations using 78‐MPa 3D printed stay‐in‐place concrete formwork cast with 35‐MPa ready‐mix concrete with reinforcements, and two conventional foundations cast entirely out of 35‐MPa concrete with reinforcements. The life cycle assessment investigates the environmental impacts of four different stages, including materials production, transportation, construction, and end‐of‐life. The materials production stage is found to dominate the life cycle results, contributing over 97% of the total CO2 emissions and over 88% of the fossil fuel depletion for each foundation. Compared to the conventional designs, the Short Flat Ribbed Beam foundation with 3D printed formwork has 22.4% lower CO2 emissions and 28.3% lower fossil fuel depletion than the Circular foundation, and 2.0% higher CO2 and 5.9% lower fossil fuel depletion compared to the Tapered foundation. Parametric studies indicate that reducing cement content and increasing recycled content in printed concrete can significantly reduce the overall life cycle impacts of the foundations.

AbstractIntroductionThe United Kingdom Registry of Endocrine and Thyroid Surgery (UKRETS) holds the largest database of pediatric parathyroidectomy cases globally. There are currently no quoted acceptable cure or complication rates in the literature.MethodsThis retrospective database analysis evaluates the efficacy and safety of targeted parathyroidectomy (tPTx) and bilateral neck exploration (BNE) in first‐time parathyroidectomy for pediatric primary hyperparathyroidism (PHPT) through analysis of the UKRETS database (1995–2022). Pre‐, intra‐ and postoperative outcomes were assessed and analyzed.Results168 cases underwent parathyroidectomy; 25 (15%) familial and 143 (85%) sporadic PHPT. 69% were female with a mean age of 10 years (Range 0–17). BNE was the most common operative approach (61%; n = 103/168). The most frequently used imaging modality was US (80%; n = 135/168). Mean number of glands excised in familial cases was three compared to one gland in sporadic cases (p < 0.05). Familial cases had a significantly higher rate of postoperative hypocalcemia (32% vs. 9%, p < 0.05) and all were BNE. Cure rate was 96.9% (n = 127/131), with differences in cure rates that did not reach statistical significance (sporadic 98.2% vs. familial 90.5%, p = 0.06). Preoperative localization (image‐positive or negative) made no difference to cure rates in either familial (90% vs. 91%, p = 0.94) or sporadic (97.5% vs. 100%, p = 0.4) cases.ConclusionsThis analysis demonstrates that first‐time pediatric parathyroidectomy for PHPT is safe and effective. Familial cases have a higher rate of postoperative hypocalcemia; therefore, parents should be informed of this when consented. Targeted parathyroidectomy is safe and effective in both sporadic and familial cases, as long as there is positive preoperative imaging.

AbstractBackgroundLaparoscopy training remains inaccessible in many low‐ and middle‐income countries, including Liberia. We assessed the availability of laparoscopy and feasibility of implementing a laparoscopic program among Liberian surgeons and trainees.MethodsThis mixed‐methods study utilized a 32‐item survey and semi‐structured interviews on laparoscopic experience, knowledge, desires, barriers, patient perceptions, and training opportunities among surgeons and trainees at Liberia's two main teaching hospitals in March 2023. Data analysis utilized summed knowledge and desirability scores, descriptive statistics, and qualitative content analysis.Results31 interns, residents, and consultants participated, comprising 60% of Liberia's surgeons. Laparoscopic training (32%) and experience (16%) was low, with exposure limited to those training outside Liberia (p = 0.001). While laparoscopy knowledge varied (29% low, 55% medium, 16% high), participants expressed high interest in training (100%) and willingness to pay (52%). Interviews revealed four themes: desires for training, patient acceptability, feasibility of technology‐based training, and barriers including limited equipment and expert trainers. At the time of survey, the only minimally invasive surgeries ever performed in Liberia were two diagnostic laparoscopies.ConclusionsThis is the first mixed‐methods study assessing laparoscopy in Liberia. Our sample, though small, comprised approximately 60% of Liberian surgeons in both rural and urban hospitals. Findings demonstrated limited experience, variable knowledge, and high desires for training, showing feasibility for laparoscopy implementation in Liberia.

AbstractBackgroundNarrow band imaging‐magnifying endoscopy (NBI‐ME) is used to identify changes in mucosal or vascular pattern observed on GI endoscopy in real time on the basis of optical image enhancement.It has a significant role in early detection of dysplasia, premalignant, and Malignant lesions along with its depth of invasion.Materials and methodsUpper and lower GI endoscopy performed in 1742 patients who presented with gastrointestinal symptoms at this tertiary center over 5 years out of which 1623 were evaluated with both NBI‐ME and histopathology. Real time endoscopic assessment was performed. Targeted biopsies were taken for comparative analysis.ResultsOf the 1742 patients, 119 were excluded from the study. 807 underwent upper GI endoscopy and 816 underwent lower GI endoscopy. Mean age of presentation was 38 +/− 2.7 years. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of NBI‐ME for neoplastic esophageal lesions were 96.3%, 90.6%, 91.1%, 96.03%, respectively. For Barrett's esophagus it was 95.4%, 90.7%, 86.1%, and 90.7%; For gastric neoplastic lesions the values were 96.1%, 91.04%, 83.8%, and 97.9%. For colorectal it was 96.7%, 91.3%, 88.0%, and 97.7%. Overall sensitivity, specificity, PPV, and NPV of NBI‐ME for neoplastic lesions (both upper and lower GI) were 96.2%, 91.0%, 96.2%, and 97.2%. Of the 1623 patients, 951 received medical management with regular surveillance and 672 patients with high‐grade dysplasia, premalignant, and malignant conditions underwent interventions in form of either endoscopy or surgery.ConclusionNBI‐ME has a greater role and can be considered as an effective tool in making early diagnosis and guiding optimum treatment.

AbstractBackgroundUrologic emergencies are common and complications from their management are high. Simulation‐based education (SBE) is a highly effective training method, allowing trainees to learn both technical and nontechnical skills in a safe environment. Training in the management of urological emergencies is limited in many healthcare settings, so we performed a needs assessment for a urological emergencies SBE course in Ethiopia.MethodsThis study presents data from a descriptive cross‐sectional, survey‐based survey of consultants and residents in the Ethiopian surgical community. The survey was disseminated using online Google Forms, through social media (WhatsApp), and to colleagues in the College of Surgeons of East, Central and Southern Africa (COSECSA) via email and social media.ResultsOne hundred‐seven results were received; two were discarded due to incomplete data. Fifty three of the respondents were general surgeons and 38 of the respondents were urologists. Sixty nine respondents strongly agreed that simulation‐based training was important for first‐year surgical residents, whereas twenty‐five respondents agreed and nine respondents strongly disagreed; one respondent disagreed and one was neutral. Eighty seven respondents suggested a 3‐day training course, whereas 17 respondents suggested a two‐day course. More than 80 of the respondents rated training in the management of acute urinary retention, acute scrotum, urethral, and suprapubic catheterization as extreme or very important and 79 respondents wanted education about urologic trauma and Fournier's gangrene.ConclusionSurgical and urology residents in Ethiopia have expressed a need for, and a strong interest in, simulation‐based urological emergency training.
Numerical study of Casson dusty hybrid nanofluid flow with volume fraction over a Darcy–Forchheimer porous medium
Authors: Chutia Barbie 
Published: September 2024

AbstractThis study develops a mathematical model for dusty Casson hybrid nanofluid flow over a vertical stretching sheet, considering the influence of volume fractions for the dust particles and nanoparticles, magnetic field and Darcy–Forchheimer penetrating medium. The nanoparticles used are TC4 (Ti‐6Al‐4V) and Nichrome (80% Ni and 20% Cr), suspended in unused engine oil (EO). The governing partial differential equations are transformed into ordinary ones using suitable transforms. Solutions are obtained numerically via the Matlab built‐in program Bvp4c technique and represent graphically the velocity, temperature, and concentration profiles for both the fluid and dust phases. Additionally, tabular forms present wall shear stress and heat transfer rate variations under different parameter values. It is found that the enhancing volume fraction parameter helps to boost the magnitude of shear stress, heat, and mass diffusivity.
Adapting Strategies of Portfolio Management to VUCA Environments: The Case of Romania
Authors: Boscoianu Mircea , Ceocea Costel , Țîțu Aurel Mihail 
Published: September 2024

AbstractThe recent multiple crises of the 2020–2023 imposed the integration of the concept of VUCA environments (volatility–uncertainty–complexity–ambiguity) at the level of the capital markets, as an indisputable reality. These processes have, in fact, led to major changes in the perception of the markets impacting the understanding of new problems, respectively, the action of the managers and the implementation of the portfolio management strategies. Managing portfolios in VUCA environments involves reconsidering portfolio management objectives that must be better adapted to investors’ requirements in a dynamic spectral context. Portfolio managers must now anticipate these demands and needs and design new strategies and products, better adapted to these changes. In addition, there are a number of problems specific to emerging markets: the lack of major essential market structures or dysfunctions (futures, options), the reduced liquidity of the capital market and the inconsistent structure of stakeholders, and insufficient or even lack of knowledge in the field of capital markets. In emerging markets, there are investment funds (open and closed) focused only on instruments listed in the first category of the stock exchange, respectively, treasury and high quality corporate bonds. The investment funds are generally oriented towards passive management, with only extremely few examples of strategic orientation towards active portfolio management. The lack of essential infrastructures (futures, options) is somehow compensated by the development of pension funds that are becoming major players with presence and performance in the markets. The number of retail investors remains extremely small, but the good news is given by the possibilities of further increase in the near future. The research methodology starts from the design, configuration, implementation, and interpretation of questionnaires addressed to investors, respectively, fund managers. Starting from the resulting conclusions, the future intentions regarding the active management of portfolios and the design of new products such as ETFs (exchange traded funds) or the implementation of new strategies are deciphered. To incorporate the dynamic aspects, the real options paradigm and the dynamic capabilities paradigm are also integrated. The possible contributions refer to deciphering the current aspects of portfolio management, understanding strategies and adaptation solutions, like portfolio rotation (growth-value-bonds), and understanding how to design products better adapted to current market conditions.

Blaustein and His Times
Authors: Płotka Witold 
Published: September 2024

AbstractLeopold Blaustein (1905–1942 [or 1944]) was educated at Jan Kazimierz University in Lvov and graduated under Kazimierz Twardowski (1866–1938), a student of Franz Brentano (1838–1917) in Vienna. Blaustein’s academic activity covered almost two decades—the 1920s and 1930s—when philosophy in Poland was renewed as a scientific discipline and dominated by (but certainly not reducible to) the Lvov–Warsaw School. Roman Ingarden (1893–1970), who was also Blaustein’s teacher in Lvov, once described this renewal as a change in the “philosophical atmosphere” in Poland; for him, Twardowski “[…] did in fact outline in a certain sense a new period of Polish philosophy. Namely, he imposed on philosophical research in Poland a new style of work.” Ingarden explains that this renewal consisted in an attempt to have clear-cut philosophical notions and well-defined language, in addition to solid justifications for discussed theses. To that extent, Twardowski’s efforts can be regarded as a broad meta-philosophical project which was developed in diverging directions, including logic, ontology, epistemology, ethics, aesthetics, etc.
