Authors: Maciel-Flores Cristhian Eduardo , Lozano-Alvarez Juan Antonio , Bivián-Castro Egla Yareth
Published: February 2024

Most diseases that affect human beings across the world are now treated with drugs of organic origin. However, some of these are associated with side effects, toxicity, and resistance phenomena. For the treatment of many illnesses, the development of new molecules with pharmacological potential is now an urgent matter. The biological activities of metal complexes have been reported to have antitumor, antimicrobial, anti-inflammatory, anti-infective and antiparasitic effects, amongst others. Metal complexes are effective because they possess unique properties. For example, the complex entity possesses the effective biological activity, then the formation of coordination bonds between the metal ions and ligands is controlled, metal ions provide it with extraordinary mechanisms of action because of characteristics such as d-orbitals, oxidation states, and specific orientations; metal complexes also exhibit good stability and good physicochemical properties such as water solubility. Platinum is a transition metal widely used in the design of drugs with antineoplastic activities; however, platinum is associated with side effects which have made it necessary to search for, and design, novel complexes based on other metals. Copper is a biometal which is found in living systems; it is now used in the design of metal complexes with biological activities that have demonstrated antitumoral, antimicrobial and anti-inflammatory effects, amongst others. In this review, we consider the open horizons of Cu(II)- and Pt(II)-based complexes, new trends in their design, their synthesis, their biological activities and their targets of action.

Authors: Sacco Nicolás , Iguini Alexander , Gamba Ilaria , Marchesini Fernanda Albana , García Gonzalo
Published: February 2024

The integration of clean energy generation with wastewater treatment holds promise for addressing both environmental and energy concerns. Focusing on photocatalytic hydrogen production and wastewater treatment, this study introduces PdIn/TiO2 catalysts for the simultaneous removal of the pharmaceutical contaminant paracetamol (PTM) and hydrogen production. Physicochemical characterization showed a high distribution of Pd and In on the support as well as a high interaction with it. The Pd and In deposition enhance the light absorption capability and significantly improve the hydrogen evolution reaction (HER) in the absence and presence of paracetamol compared to TiO2. On the other hand, the photoelectroxidation of PTM at TiO2 and PdIn/TiO2 follows the full mineralization path and, accordingly, is limited by the adsorption of intermediate species on the electrode surface. Thus, PdIn-doped TiO2 stands out as a promising photoelectrocatalyst, showcasing enhanced physicochemical properties and superior photoelectrocatalytic performance. This underscores its potential for both environmental remediation and sustainable hydrogen production.

Published: February 2024

Cyclic adenosine monophosphate (cAMP) is an important second messenger in cells, mediating various stimulation signals such as the growth and development of organisms and stress and participating in regulating various biological processes of cells. This article explores the quantitative determination of cAMP in plants using High-Performance Liquid Chromatography (HPLC) and applies this method to analyzing the changes in cAMP content during the process of plant response to the bacterial quorum sensing signal N-acyl homoserine lactone (AHL). Research has shown that the optimal detection conditions for HPLC are as follows: the chromatographic column is Venusil MP C18 (2), the mobile phase is methanol–water (0.1% trifluoroacetic acid) (v:v, 10:90), the detection wavelength is 259 nm, the column temperature is 35 °C, and the flow rate is 0.8 mL/min. The precision of the standard sample of this method is 98.21%, the precision of the sample is 98.87%, and the recovery rate is 101.067%. The optimal extraction conditions for cAMP in Arabidopsis are to use 15% methanol ultrasonic extraction for 10 min, followed by a 40 °C water bath for 4 h. Bacterial AHL signal processing can significantly stimulate an increase in cAMP levels in Arabidopsis leaves and roots. The establishment of HPLC detection methods for the cAMP content in plants is of great significance for in-depth research on the signal transduction mechanisms of plant–bacterial interactions.

Enhalus arcoides is a highly beneficial type of seagrass. Prior studies have presented proof of the bioactivity of E. acoroides, suggesting its potential to combat cancer. Therefore, this study aims to delve deeper into E. acoroides bioactive molecule profiles and their direct biological anticancer activities potentials through the combination of in-silico and in-vitro studies. This study conducted metabolite profile analysis on E. acoroides utilizing HPLC-ESI-HRMS/MS analysis. Two extraction techniques, ethanol and hexane, were employed for the extraction process. Furthermore, the in-silico study was conducted using molecular docking simulations on the HER2, EGFR tyrosine kinase and HIF-1α protein receptor. Afterward, the antioxidant activity of E. acoroides metabolites was examined to ABTS, and the antiproliferative activity was tested using an MTT assay. An in-silico study revealed its ability to combat breast cancer by inhibiting the HER2/EGFR/HIF-1α pathway through molecular docking. In addition, the MTT assay demonstrated that higher dosages of metabolites from E. acoroides increased the effectiveness of toxicity against cancer cell lines. Additionally, the study demonstrated that the metabolites possess the ability to function as potent antioxidants, effectively inhibiting a series of carcinogenic mechanisms. Ultimately, this study showed a new approach to unveiling the E. acoroides metabolites’ anticancer activity through inhibiting HER2/EGFR/HIF-1α receptors, with great cytotoxicity and a potent antioxidant property to prevent a carcinogenic cascade.

Published: February 2024

High-resolution imaging of Cu/low-k on-chip interconnect stacks in advanced microelectronic products is demonstrated using full-field transmission X-ray microscopy (TXM). The comparison of two lens-based laboratory X-ray microscopes that are operated at two different photon energies, 8.0 keV and 9.2 keV, shows a contrast enhancement for imaging of copper nanostructures embedded in insulating organosilicate glass of a factor of 5 if 9.2 keV photons are used. Photons with this energy (Ga-Kα radiation) are generated from a Ga-containing target of a laboratory X-ray source applying the liquid-metal-jet technology. The 5 times higher contrast compared to the use of Cu-Kα radiation (8.0 keV photon energy) from a rotating anode X-ray source is caused by the fact that the energy of the Ga-Kα emission line is slightly higher than that of the Cu-K absorption edge (9.0 keV photon energy). The use of Ga-Kα radiation is of particular advantage for imaging of copper interconnects with dimensions from several 100 nm down to several 10 nm in a Cu/SiO2 or Cu/low-k backend-of-line stack. Physical failure analysis and reliability engineering in the semiconductor industry will benefit from high-contrast X-ray images of sub-μm copper structures in microchips.

Published: February 2024

The leakage of the electronic current of a laser diode (LD) has some significant influences on the performance of the LD. In this study, commercial simulation software LASTIP is used to numerically evaluate the performances of LDs by using different wavelengths and Al contents of the electron blocking layer (EBL). These LDs a adopt multilayer structure, which contains cladding layers, waveguide layers, multiple quantum well layers, contact layers and an AlxGa1−xN EBL. The influence mechanism of EBL is theoretically examined by analyzing the simulated performances. It is found that for short-wavelength violet LDs, the electrical and optical properties of the LD will reach the optimum state when the Al content (x) in the EBL is nearly 0.25. For long-wavelength green LDs, it will achieve optimum electrical and optical properties when the Al content in the EBL is as low as possible. We also compare the simulation results of LDs with emission wavelengths in the range of violet and green, including blue cyan, for a more general evaluation. According to the simulated results, it is verified that the influence of the EBL’s Al content on LD performance enhances as the wavelength increases.
Five-Band Tunable Terahertz Metamaterial Absorber Using Two Sets of Different-Sized Graphene-Based Copper-Coin-like Resonators
Authors: Wang Jieru , Qin Xuefeng , Zhao Qian , Duan Guiyuan , Wang Ben-Xin
Published: February 2024

In this paper, a five-band metamaterial absorber with a tunable function in a terahertz band is proposed, which consists of a gold grounding layer, a polyimide dielectric layer, and a periodic patterned graphene layer. The patterned graphene layer is constructed from two sets of copper-coin-shaped structures of different sizes. The designed absorber achieves absorptions of 96.4%, 99.4%, 99.8%, 98.4%, and 99.9% at 4.62 THz, 7.29 THz, 7.70 THz, 8.19 THz, and 8.93 THz, respectively, with an average absorption intensity of 98.78%. The physical mechanism of this five-band absorber was explained by the impedance matching principle and electric field distribution. The absorption performance of the five-band absorber can be effectively tuned by changing the geometry of the patterned graphene array and the thickness of the dielectric layer. Given that the resonant frequency of the absorber varies in proportion to the Fermi level, by varying the Fermi level of the graphene hypersurface, we can achieve the continuous tuning of the absorption performance over a wide frequency range. The five-band absorber has a stable absorption performance over a wide incidence angle of 0–65°, and by combining the merits of high absorption, dynamic adjustability, and a large number of absorption peaks, the given absorber could have great potential for applications in nondestructive testing, imaging, communication, sensing, and detectors.
Design and Sensitivity Analysis of Mechanically Actuated Digital Radial Piston Pumps
Authors: Pate Keith , Marschand James R. , Breidi Farid , Salem Tawfiq , Lumkes John
Published: February 2024

One major challenge in fluid power is the improvement and optimization of the efficiency of mobile hydraulic systems. Conventional fluid power systems often exhibit relatively low overall efficiencies caused by inefficiencies in the various components, such as a prime mover, variable displacement pump, valves, fittings, hoses, and actuators. While each component contributes to the losses in the overall system, the pump converts the mechanical shaft energy from the prime mover to energy transmitted hydraulically and is one of the most crucial components impacting overall system efficiency. Using on/off technologies, new pump architectures have enabled the opportunity to increase the efficiency over conventional designs using positive sealing valves in place of conventional port plate designs. This work proposes, investigates, and assesses the development and optimization of a digital variable displacement pump using a novel cam actuation technique on radial piston pumps. The novelty of this work is the development and parameter optimization of a mechanically actuated digital radial piston pump that can achieve high efficiencies from minimum to maximum displacement compared to common conventional variable displacement pump technologies. In this study, a sensitivity analysis is conducted to study the parameters of the system to optimize the pump. The parameters assessed in this study include: the valve bore size, cam transition and compression angles, piston diameter, and dead volume in the pumping chamber. The simulation results show that after optimizing the parameters of the system, the pump in design could reach a maximum efficiency of approximately 93% and was capable of upholding efficiencies above 80% between 30–100% displacement.
The Middle Pleistocene Hippopotamus from Malagrotta (Latium, Italy): New Data and Future Perspectives
Authors: Martino Roberta , Marra Fabrizio , Ríos María , Pandolfi Luca
Published: February 2024

The Middle Pleistocene was characterized by the presence in continental Europe of at least two different species of hippopotamus: Hippopotamus antiquus and H. amphibius. Although suspected, the presence of both hippopotamuses in the same geographical area has not yet been proven. The following manuscript describes findings from Malagrotta (Rome, central Italy), dating back to the time span between 0.45 and 0.38 Ma. These findings offer new insights into the Middle Pleistocene period. The fragmented mandible has a slender and low corpus, the humerus is robust with a deltoid tuberosity placed medially on the diaphysis, the unciform shows a facet for the MCIV wider than the one for the MCV and the calcaneum is clepsydra-shaped. The morphological characteristics of the sample are closer to those of H. antiquus, despite the fact that the morphometric measurements are smaller than those of the samples coming from Valdarno (Italy), Untermaßfeld (Germany) or Colle Curti (Italy). Considering all the information, the material from Malagrotta is here attributed to H. cf. antiquus, indicating the survival of the European hippopotamus until at least 0.38 Ma in central Italy. The coexistence of H. amphibius and H. antiquus in the same geographical area is also discussed.

Market Equilibrium and the Cost of Capital with Heterogeneous Investment Horizons
Authors: Levy Moshe , Levy Haim
Published: February 2024

Expected returns, variances, betas, and alphas are all non-linear functions of the investment horizon. This seems to be a fatal conceptual problem for the capital asset pricing model (CAPM), which assumes a unique common horizon for all investors. We show that under the standard assumptions, the theoretical CAPM equilibrium surprisingly holds with the 1-period parameters, even when investors have heterogeneous and possibly much longer horizons. This is true not only for risk-averse investors, but for any investors with non-decreasing preferences, including prospect theory investors. Thus, the widespread practice of using monthly betas to estimate the cost of capital is theoretically justified.

Published: February 2024

Hearing loss (HL) is associated with poorer language development and school performance. Ototoxic substances such as metals and solvents, including benzene, are a risk factor associated with HL. This study examines potential associations between the benzene metabolite trans,trans-muconic acid (t,t-MA) and HL in youth of the National Health and Nutrition Examination Survey (NHANES). Logistic regression calculated adjusted odds ratio (aOR) associations between HL and urinary t,t-MA quartiles, natural-log transformed, and doubled urinary t,t-MA. Hearing threshold pure-tone average (PTA) at speech frequencies (SF) 0.5, 1, 2, and 4 kHz and high frequencies (HF) 3, 4, and 6 kHz were analyzed for slight HL (PTA > 15 dB) and mild HL (PTA > 20 dB). Urinary t,t-MA was statistically significantly associated with both slight SF and HF HL. For each doubling of t,t-MA there were increased odds of having slight SFHL (aOR = 1.42; 95% CI: 1.05, 1.92), slight HFHL (aOR = 1.31; 95% CI: 1.03, 1.66), mild SFHL (aOR = 1.60; 95% CI: 1.10, 2.32), and mild HFHL (aOR = 1.45; 95% CI: 1.03, 2.04). To our knowledge, this is the first population-based report of an association between SFHL, HFHL, and the benzene metabolite t,t-MA in youth 6 to 19 years old.
General practitioners' decision making managing uncomplicated urinary tract infections in women: a qualitative study
Authors: Kurotschka Peter K , Hemkeppler Juliane , Gierszewski David , Ghirotto Luca , Gágyor Ildikó
Published: February 2024

Background

To be effective, interventions aimed at increasing the appropriateness of antibiotic use in primary care should consider the perspectives of prescribing physicians.

Aim

To explore the decision making of general practitioners (GPs) when managing uncomplicated urinary tract infections (uUTIs) in women.

Design & setting

A qualitative study using semi-structured interviews with 22 GPs in Bavaria and Baden-Württemberg (southern Germany).

Method

Verbatim transcripts were analysed through inductive qualitative content analysis.

Results

We generated the following three main themes: factors facilitating the decision making; factors complicating the decision making; and consultation modalities. According to participants, following evidence-based recommendations makes the prescription decision smoother. GPs' and patients’ prior experiences and beliefs guides decisions towards certain antibiotics, even if those experiences and beliefs contradict evidence-based recommendations. Patient expectations and demands also condition antibiotic prescribing, favouring it. Organisational constraints, such as time pressure, the day of the week (for example, before weekends), and a lower cost of antibiotics for patients than alternative treatments favour the decision to prescribe antibiotics. Diagnostic and prognostic uncertainty complicates decision making, as does scepticism towards evidence-based recommendations. Discordance within the patient–doctor relationship contributed to this complexity. Regarding consultation modalities, a more in-depth consultation and shared decision making were seen as helpful in this process.

Conclusion

We identified different factors as intervening against or for a straightforward management decision when dealing with women with uUTIs. They reveal the complexity behind the GPs’ decision making. Providing GPs with easy-to-apply guidance while removing economic constraints to allocate sufficient consultation time, and supporting shared decision making may help GPs appropriately manage uUTIs in women.

Authors: Norori Natalia , de Biase Chiara , Wong Yui Hang , Crabtree Sadie Robson , Cox Matt , Appleby Esther , Seggie Andrew , Brown Rachel , Rylance Amy
Published: February 2024

Background

The UK has an informed choice testing policy for prostate cancer. The prostate-specific antigen (PSA) blood test is available for free to any man aged ≥50 years who requests it and has been informed of the harms and benefits. This policy leads to differences in PSA testing rates, which can exacerbate health inequalities.

Aim

To assess whether Prostate Cancer UK’s risk checker helps men at risk of prostate cancer make an informed choice about the PSA test.

Design & setting

Mixed-methods study in the UK.

Method

In total, 1181 men at risk, their partners, and clinical experts participated in surveys, focus groups, and one-to-one interviews. Data on risk checker completions by sociodemographic factors were analysed over time. Data from general practices that sent the risk checker to their patients were collected and analysed for service monitoring purposes.

Results

There was a strong assumption that testing must be good, and therefore a need to emphasise the pros and cons of the test and that having it was the patient’s decision. Men believed their GP would invite them for PSA testing. On the impact of the risk checker, 79.6% of men who completed it had at least one prostate cancer risk factor; the average time they interacted with the information in the tool was 9 minutes 28 seconds; and 75.7% felt the tool had equipped them to make an informed choice.

Conclusion

Online decision-making tools, such as the risk checker, can help reach men at high risk of prostate cancer and support them in making an informed choice about the PSA test.

Abuse in construction work auctioned by the government or being a partner of the government is one form of criminal offense that harms the state. This research uses a legal approach with a focus on Law Number 18 of 1999 concerning Construction Services. This study found that the law is still lacking in providing legal certainty and meeting the development needs of the implementation of construction services. Changes in regulations or requirements in the selection document for the procurement of goods/services are needed that have a major effect on the implementation of work, so that termination of the contract can have a detrimental impact on the state. The importance of provisions and legal certainty regarding regulations in the termination of construction work contracts is so that there is no overlap or difference in perception in interpreting the rules regarding the disbursement of implementation guarantees. This research highlights the importance of clear legal regulation in regulating construction work contracts to prevent state financial losses.

Fuel is one of the most critical needs for the community in carrying out various household activities dominated by fuel oil. Meanwhile, the availability of fuel is increasingly running low. Most people in the Botumoito area in Gorontalo province work in the agricultural sector with low local income. Availability of fuels such as kerosene and gas there is quite challenging because there is no source or supply of gas either directly from the gas field or terminal. The government needs to make the right policy on fuel selection according to the problems in the region. This research aims to design and build a decision support system for selecting the best fuel and implementing the Weighted Product (WP) method into the system. The method used in designing and manufacturing this system is the waterfall method. This research results in a decision support system that can help fuel ranking. The ranking results are based on the magnitude of the Vector (V) value obtained from testing ten alternative fuels. Bioethanol occupies the top priority with a vector value of 0.152. This research can help consultants, fuel experts, and local governments speed up their work in determining the best household fuel according to their respective regions.

Sustainable development must embrace the three basic principles of ecological sustainability, social and cultural sustainability, and economic sustainability for both present and future generations. The community must participate in the implementation of tourism in their area, because this involves economic, social and cultural issues of the community as well as the conservation of the nature in which they live. One of the concepts of sustainable tourism development that is oriented towards community empowerment is Community Based Tourism (CBT) which is a critical idea from conventional tourism development which often ignores rights and does not involve the community in the process. The research method used is descriptive qualitative with data collection techniques through the stages of observation, interviews and focus group discussions and documentation. Research activities consist of preliminary studies, conceptual modeling, validation and revision, and model testing. Data analysis uses an interactive analytical model from Miles and Huberman which allows data analysis when researchers are in the field or after returning from the field. This research resulted in a development concept based on community empowerment through three stages of development: (1) tourism destination development program, (2) tourism marketing development program, (3) partnership development program.

Published: February 2024

This study examines the role of comments on the TikTok social media platform in shaping the image of tourist destinations, focusing on Borobudur Temple, a world heritage site in Indonesia. A thematic analysis of comments on TikTok reveals the public's perception of Borobudur Temple as a historical destination enriched with spiritual values and myths. Terms such as "myth" and "belief" predominate, highlighting the temple's uniqueness and religious backdrop. Social media, particularly TikTok, plays a crucial role in shaping these perceptions. By understanding and addressing these perceptions, marketing strategies on digital platforms can be more effective, enhancing the global appeal of Borobudur Temple. The overall findings underscore the power of social media in shaping the image of tourist destinations and provide recommendations for stakeholders in the tourism industry.

وقفيَّة طاهر موسى العرابي في مدينتي نابلس وجنين وجوارهما رمضان 1256هـ/ تشرين الأول 1840م: دراسة تحليلية
Authors: Al-Hizmawi Muhammad Majid
Published: February 2024

تهدف هذه الدراسة إلى البحث في وقفية طاهر موسى العرابي في مدينتي نابلس وجنين وجوارهما المسجلة في محكمة نابلس الشرعية في غرة شهر رمضان 1256هـ/26 تشرين الأول 1840م. وقد اقتضت خطة الموضوع تقسيم البحث إلى أربعة محاور، تناول المحور الأول حياة الواقف، وخصص المحور الثاني للحديث عن نص الوقفية من حيث اللغة والشروط الواجب توفرها في الواقف، أما المحور الثالث فتناول بالتحليل العقارات الموقوفة، وتحدث المحور الرابع عن الشروط التي وضعها الواقف. اعتمدت الدراسة بشكل رئيس على نص الوقفية موضوع الدراسة، إضافة إلى عدد من سجلات محكمة نابلس الشرعية التي تُشكل مصدرًا تاريخيًا فريدًا يقدم معلومات غنية وقيّمة لا تتوفر في المصادر الأخرى. وتوجد نسخة مصورة منها في كل من مركز الوثائق والمخطوطات في الجامعة الأردنية، ومؤسسة احياء التراث التابعة لوزارة الأوقاف الفلسطينية. واتبع الباحث في هذه الدراسة أربعة مناهج المنهجين الاستقرائي والتاريخي اللذين يعتمدان على استقراء نص الوقفية وتحليله، أما المنهج الثالث فكان المنهج الكمي الإحصائي الذي اعتمد على الجداول وما تضمنته من بيانات رقمية وتحليلها، واستخدم المنهج المقارن من خلال المقارنة بين العقارات الموقوفة من جهة والعقارات التي حصل عليها الواقف سواء بالشراء أو الاستبدال التي اعتمد الباحث في جمعها من سجلات محكمة نابلس الشرعية. وخلصت الدراسة إلى نتائج عدة، أهمها: أن الوثيقة الوقفية تُعد بما تضمنتها من معلومات مختلفة من المصادر الأولى في التدوين التاريخي، كما تُشكل شاهدًا على تاريخ مدينة نابلس يعكس صورة واقعية للحياة العامة للمجتمع النابلسي خلال فترة الدراسة. وأخيرًا تسهم الأوقاف الذرية من خلال حفاظها على استمرارية العقارات الموقوفة وعدم تجزئتها وتوزيعها بين الورثة في التنمية الاقتصادية والاجتماعية للمجتمع بمختلف فئاته الاجتماعية.

Published: February 2024

The developed model of a resistive-transistor thermoelectric converter, the technique for identifying its parameters and the results of circuit simulation using the proposed model of an RMS-DC converter are considered. The electrical circuit of the RMS-DC converter is given, the dependences of the conversion error on the input voltage level obtained by circuit modeling, on the basis of which the main requirements for reducing the error are formulated. The application of operational amplifiers of the OAmp11.2 type with input junction field-effect transistors, previously developed on the master slice array МН2ХА031, makes it possible to implement a precision RMS-DC converter in the form of a microassembly containing two crystals of the ПН001 thermoelectric converter, one МН2ХА031 crystal with a signal processing circuit and external filter capacitors. Circuit simulation showed that such a converter remains operational at an absorbed dose of gamma radiation equal to 1 Mrad and exposure to a neutron fluence of 1 ⋅ 1013 n/cm2 .

Authors: Tatur М. М. , Ihnatsiuk М. S. , Konikov А. D.
Published: February 2024

This article proposes the formalized methodology for model-based design of mobile platform management systems. The methodology is based on an alternative approach to development, when the model of controlled object is firstly created as a design tool, and then control algorithms are developed. This allows to find the most successful algorithms and select control parameters that are close to optimal in the process of model-based design. As examples, two typical tasks from the field of mobile platform management are given - braking and steering control. The proposed methodology has sufficient unification to be used in the design of control systems for mobile platforms of various types, with different positioning systems, principles of navigation and autopiloting.
