Published: September 2022

The process of deriving the hydrological parameters in the GIS environment requires semi-automated procedures that depend on the user’s experience with the tools designed within the system, and this in turn may cause technical errors as a result of implementing the sequential steps that address an issue, so there was a need to develop tools that depend on the total automated derivation reduce the number of steps while reducing the time required for implementation. As a result, in the presented work, a hydrological toll was created as an automated workflow using Python and ArcGIS Model Builder, which will be explained. The workflow for this tool was developed in Python and applied to Iraq's northeast region. Through the statistical comparison of all derived stream configuration results using DEM, an ideal threshold value was found to maximize drainage configuration. The code was successful in automatically estimating the right ranking of specified stream orders without any further manual processes. Therefore, the developed tool saves effort and time, making it an extremely valuable function for large catchment basins.

Effects of Groove Structure on Spray Characteristics of a Throttleable Pintle Injector
Authors: Heo Subeom , Kim Dae Hwan , Yoon Youngbin
Published: September 2022

Throttleable rocket engines are used for various purposes, including vertical landing of launch vehicles and soft landing on the surface of celestial bodies. The use of a throttleable pintle injector is a representative throttling method because of its ability to maintain the spray characteristics under different throttling levels. However, previous studies have reported changes in the spray characteristics of gas–liquid pintle injectors with varying throttling levels. To address this issue, a pintle tip with groove structure was developed in this study. Cold flow experiments were performed using normal and grooved pintle tips for a gas–liquid pintle injector, and the spray angle and average droplet size of the pintle injector were measured and compared. By changing the momentum and structure of the radial flow with added grooves, the spray angle increased and the droplet size decreased. The results indicate that adopting a grooved pintle tip can improve the spray characteristics of a pintle injector in terms of its correlation with combustion performance, particularly at low throttling levels. Additionally, a grooved pintle tip reduces the changes in spray characteristics under varying throttling levels, which is advantageous from the perspective of design simplicity.

The paper proposes a mathematical model for calculating the main parameters of a controlled gas flow in the process of designing and creating a calibration stand for static and total pressure receivers, which allows, before the stand certification, to identify the features and pattern of the distribution of these parameters along the radius and length of the gas flow jet. Obtaining a given controlled gas flow, in turn, is associated with the calculation and manufacture of the nozzle. The paper proposes the use of a subsonic nozzle calculated according to the Vitoshinsky formula, which allows creating a given gas flow rate in the working part of the calibration stand depending on the gas flow rate (three modes are considered). The results of calculation of such gas flow parameters as longitudinal velocity, static pressure and static temperature at different distances from the nozzle exit (at the nozzle exit, at a distance of 2Ra, at a distance of 5Ra) are presented.

Published: September 2022

In the work, dual electroinductive spherical sensors, which are a constructive combination of two double sensors into one, are subjected to experimental studies in a non-uniform electric field. Dual sensors are an integral part of a new method for measuring inhomogeneous electric fields by average value. Experimental studies are aimed at confirming the possibility of using dual sensors in inhomogeneous electric fields and the method of measuring the electric field strength by the average value. To carry out experiments in a non-uniform electric field, a high-voltage measuring setup is created. The measuring setup made it possible to obtain the static characteristics of a dual sensor in an inhomogeneous electric field. Comparison of the static characteristics obtained in a homogeneous and inhomogeneous field makes it possible to estimate their errors and compare these errors with theoretically calculated ones. The comparison results have showed that the discrepancy between the static characteristics does not exceed +1,5 %, and the discrepancy in the errors of the dual sensor, estimated from experimental data in an inhomogeneous field and obtained theoretically, does not exceed ±2 % in absolute units. The obtained research results allow us to confirm the adequacy of the theory underlying the theoretical provisions laid down in the calculations of dual electric induction spherical strength sensors of the electric field.

Cytomorphology of pituitary carcinoma metastatic to liver diagnosed by fine-needle aspiration: A rare case report and review of literature
Authors: Srivastava Pallavi , Gupta Anurag , Malhotra Kiran Preet , Husain Nuzhat
Published: September 2022

Pituitary carcinomas (PCs) are rare entities constituting about 0.1–0.2% of all pituitary neoplasms. They are diagnosed by the presence of craniospinal or systemic metastasis in pituitary adenomas (PAs). The distant metastatic sites include liver, followed by bone, lung, and lymph nodes. The diagnosis of PC is rarely made on fine-needle aspiration cytology (FNAC) with only six cases reported till date; hence, the cytologic features are not well defined. Herein, we report a case of PA having high Ki-67 proliferation index and p53 expression, presenting with liver lesion 6 weeks post-surgery and diagnosed on FNA. Detailed cytomorphologic features are defined and compared. We emphasize that FNAC, along with clinic-radiologic correlation, is a cost-effective, safe, and diagnostically accurate method of diagnosing PC metastases.
Kimura’s disease: A short study of cytomorphologic features with its differential diagnosis and review of literature
Authors: Sahu Priya , Jain Swasti , Kaushal Manju
Published: September 2022

Kimura’s disease (KD) is a chronic inflammatory disorder of unknown etiology, endemic in Asia. The typical clinical manifestations include a triad of painless unilateral cervical lymphadenopathy or subcutaneous masses predominantly in the head-and-neck region, blood and tissue eosinophilia, and elevated serum immunoglobulin (Ig) E levels. Many conditions including benign and malignant may mimic KD clinically. This study reports cytologic features of seven cases of KD which were studied and correlated with histology, Ig profile, and peripheral blood examination. KD shows a good response to medical treatment; hence, fine-needle aspiration cytology in conjunction with other laboratory findings lowers the need for additional biopsy procedures for early diagnosis as well as diagnosis of recurrent lesions.

Authors: Liu Haisang , Kyosev Yordan , Jiang Gaoming
Published: September 2022

To simulate a warp-knitted product with a specific shape, a mesh-based model for modeling and simulation is proposed. The three-dimensional geometry of the final fabric is represented as a set of polygons, each of them containing information about the 3D orientation of the yarns in the warp knitted structure. Using spatial mapping, stitch coordinates are transformed from the flat mesh model to the three-dimensional mesh model and the final rendering is accomplished. The method provides yarn level data for the complete structure and can be used for speeding up the design process of clothing with warp-knitted products. Several challenges with the larger data amount and possible ways for their solutions are discussed.

Nowadays, environmental awareness is more important not to damage the living environment. Sources of the Earth have been decreasing day by day due to many natural and human-induced reasons such as global warming, waste disposal, urbanization, deforestation, etc. Harm of the textile sector on the environment is high and it needs control and awareness. Raw material production, raw material selection, water usage amount, sustainability of processes, refining of wastes, recycle and reuse strategies of textile companies have a very significant effect on the environment. With this awareness, sustainable fashion is created because customer behaviors affect both design and production. In this view, all ingredients and processes turn to the most sustainable forms as much as possible. While being environmentally friendly, required performances of garments should be met to prepare the required end product. In this study, a sustainable collection whose name is Earthsavers is prepared by using recycled raw materials, natural dyestuffs, etc. Their physical and chemical performances are tested. Results of the collection are suitable for acceptance levels and it shows that a collection can be prepared with minimum harm to the environment with at least the same performances as conventional alternatives.

Published: September 2022

Nowadays, despite the evolution of personal protective equipment (PPE), the number of firefighters injured and burned during fire extinguishing operations is still very high, leading in some cases to loss of life. Therefore, the research and development of new solutions to minimize firefighters’ heat load and skin burns, with consecutive improvements of commercial firefighters’ suits, is of extreme importance. The integration of phase change materials (PCMs) in a protective clothing system has been used to significantly reduce the incoming heat flux from the fire environment. This study consists in the development of a protective clothing system composed by a vest, specially designed to protect the torso (back, chest and abdomen) with a layer of PCM pouches, to be worn over a fire-resistant jacket – selection and design based on numerical models’ predictions. Therefore, several mockups were made, varying the number of PCM pouches and their distribution in the vest, allowing the creation of air ducts to increase the breathability of the vest. The most promising solutions are being evaluated in a real controlled environment, at a Portuguese National School of Firefighters (ENB) simulation site, using a fire manikin and thermocouples to monitor vest temperature during heat and flame exposure, and consequently to verify PCMs influence in heat protection. Results regarding the development of a PCM vest will be presented, focusing on the integration of PCM pouches and the thermal performance of the most promising solutions.

Authors: Brake Elena , Kyosev Yordan , Rose Katerina
Published: September 2022

For a holistic assessment of the interaction between the human body and tight fitted clothing, it is necessary to consider the mechanical properties of the body. Default avatars in CAD software are usually solid and do not take this interaction into account. For this purpose, a solid avatar is converted to a deformable one by using the soft body physics implementation in the simulation program Blender. The fit of a 3D garment on both avatars are compared, which allows a first evaluation of the differences between these approaches.
Stability and Metastability of Liquid water in a Machine-learned Coarse-grained Model with Short-range Interactions
Authors: Dhabal Debdas , Sankaranarayanan Subramanian , Molinero Valeria
Published: September 2022

Coarse-grained water models are ~100 times more efficient than all-atom models, enabling simulations of supercooled water and crystallization. The machine-learned monatomic model ML-BOP reproduces the experimental equation of state (EOS) and ice-liquid thermodynamics at 0.1 MPa on par with all-atom TIP4P/2005 and TIP4/Ice. These all-atom models were parameterized using high-pressure experimental data, and are either accurate for water’s EOS (TIP4P/2005) or ice-liquid equilibrium (TIP4P/Ice). ML-BOP was parameter-ized from temperature-dependent ice and liquid experimental densities and melting data at 0.1 MPa; its only pressure training is from com-pression of TIP4P/2005 ice at 0 K. Here we investigate whether ML-BOP replicates the experimental EOS and ice-water thermodynamics along all pressures of ice I. We find that ML-BOP reproduce the temperature, enthalpy, entropy and volume of melting of hexagonal ice up to 400 MPa and the EOS of water along the melting line with accuracy that rivals both TIP4P/2005 and TIP4P/Ice. We interpret that the accu-racy of ML-BOP originates from its ability to capture the shift between compact and open local structures to changes in pressure and temper-ature. ML-BOP reproduces the sharpening of the tetrahedral peak of the pair distribution function of water upon supercooling, and its pres-sure dependence. We characterize the region of metastability of liquid ML-BOP with respect to crystallization and cavitation. The accessibil-ity of ice crystallization to simulations of ML-BOP, together with its accurate representation of the thermodynamics of water, makes it prom-ising for investigating the interplay between anomalies, glass transition, and crystallization under conditions challenging to access through experiments.

Published: September 2022

Synthesis, storage, and characterization of thiol functionalized metal-organic frameworks (MOFs) is highly challenging. However, they continue to be of great interest due to their broad spectrum of applications. In this work, for the first time, a solid solution approach has been adopted to dilute the thiol content in UiO-66-(SH)2 [Universitetet i Oslo] MOF by terephthalic acid linker without influencing its topology. Detailed characterization of the mixed-linker UiO-66-(SH)2 MOF samples have been performed using powder X-ray diffraction (PXRD), N2 sorption, X-ray photoelectron spectroscopy (XPS) and electron microscopy. The solid dilution had an overall impact on the crystallinity, defects, porosity and particle size of the UiO-66-(SH)2 framework. This study has the potential to significantly influence the syntheses of nanoscale thiol functionalized MOF materials and their applications in photocatalysis, water purification and drug delivery. This work also incorporates post synthetic oxidation (PSO) to produce sulfonic acid tagged mixed-linker UiO-66 frameworks. The solid dilution has been found to be critical in preventing the frameworks from losing their crystallinity and porosity, upon activation. Thus, this work also paves the way for a general strategy to impart stability to sulfonic acid tagged UiO-66 framework having wide ranging applications.

Published: September 2022

A Negishi coupling based synthesis of 1,2,4,5-tetra(9-anthryl)benzene derivatives, possessing X-shaped molecular structures, is described. The results of X-ray crystallographic analysis show that two-dimensional highly ordered packing structure of the crystalline state of the unsubstituted derivative is a consequence of intermolecular π-π and CH-π interactions between anthracene units. Photoirradiation of the unsubstituted derivative as a precipitated solution promotes intramolecular [4+4] photocycloaddition reactions between both adjacent pairs of anthracene units to produce a crystalline polycyclic product having a unique 1.700 Å long carbon-carbon single bond. Furthermore, charge-transfer complexes, displaying near-infrared absorption and emission, are generated by co-crystallization of the X-shaped unsubstituted member of the group with electron-acceptor molecules.

Here we report six novel, easily accessible BODIPY‐based agents for cancer treatment. In contrast to established photodynamic therapy (PDT) agents, these BODIPY-based compounds show additional photothermal activity and their cytotoxicity is not dependent on the generation of reactive oxygen species (ROS). The agents show high photocytotoxicity upon irradiation with light and low dark toxicity in different cancer cell lines in 2D culture as well as in 3D multicellular tumour spheroids (MCTSs). The ratio of dark to light toxicity (phototoxic index, PI) of these agents reaches striking values exceeding 830ʹ000 after irradiation with energetically low doses of light at 630 nm. The oxygen‐dependent mechanism of action (MOA) of established photosensitizers (PSs) hampers effective clinical deployment of these agents. Under hypoxic conditions (0.2% O2), which are known to limit the efficiency of conventional PSs in solid tumours, a PI of 360ʹ000 was observed, indicating an oxygen-independent photothermal MOA. Both PI values are the highest reported to date. We anticipate that small molecule agents with a photothermal MOA, such as BODIPY-based compounds, may overcome this barrier and provide a new avenue to cancer therapy.

Proteolysis targeting chimeras (PROTACs) represent a new pharmacological modality to inactivate disease-causing proteins. PROTACs operate via recruiting E3 ubiquitin ligases, which enables the transfer of ubiquitin tags onto their target proteins leading to proteasomal degradation. However, several E3 ligases are validated pharmacological targets themselves, of which inhibitor of apoptosis (IAP) proteins are considered druggable in cancer. Here, we report three series of heterobifunctional PROTACs, which consist of an IAP antagonist linked to either von Hippel-Lindau- or cereblon-recruiting ligands. Hijacking E3 ligases against each other led to potent, rapid, and preferential depletion of cellular IAPs. In addition, these compounds caused complete X-chromosome-linked IAP knockdown, which was rarely observed for monovalent and homobivalent IAP antagonists. In cellular assays, degraders outperformed antagonists and showed potent inhibition of cancer cell viability. The hetero-PROTACs disclosed herein are valuable tools to facilitate studies of the biological roles of IAPs and will stimulate further efforts toward E3-targeting therapies.

Purpose: There are variety of factors that influence a customer’s selection of a bank in general. However, there is a large gap in the literature that covers a customer decision to choose between an Islamic bank and a conventional one. To this end, we try to fill this gap by using a case study in Morocco to analyse factors contributing to a consumer’s bank selection. Methodology: The analysis presented in the paper is using a case in Morocco and applying an artificial intelligence method using KANO analysis. We apply it in three stages. First, customers preferences are identified and classified according to their impact on customer’s satisfaction. Second, a Satisfaction Increasing Index (SII) is formulated. Third a Dissatisfaction Decreasing Index (DII) is formulated. Findings: The analysis shows that Islamic banking attributes (Provision of profit-loss sharing financing , Operating on Islamic law and principles, Staff knowledge of Islamic banking, Provision of interest-free loans) are required by customers in selecting an Islamic bank as opposed to a conventional bank. However, these requirements do not necessarily contribute to increasing customers’ satisfaction. Significance: To the best of our knowledge, this is perhaps the first paper which uses a Kano analysis in the context of consumers selection of an Islamic or Conventional bank Research Limitations/Implications: This Paper has the main limitation of being conducted only in Morocco. It will be interesting to see how the results would change if the country context is changed. Practical and Social Implications: The findings using these techniques, should help financial institution, whether it be Islamic or conventional banks to tailor their offerings to match consumers requirements.
Performance of Islamic and Conventional Banks: The Impact of Basel III

Published: September 2022

Purpose: To overcome the deficiencies of the Basel II and to respond the great depression of 2008, Basel III is designed to lower the default risk of banks. However, the unique business model and capital structure of Islamic banks is ignored at this point. A common banking regulation for two different types of banks may have a different impact on the profitability and cost efficiency of these banking types. In this regard, we address the question of the relative performance of both banking types in response to Basel III standards. Methodology: The study utilizes data of 79 banks, both Islamic and conventional, for the period of 2005 to 2019 from 10 different countries. For estimation, the study uses fixed-effect regression analysis. Findings: We find a positive impact of Basel III regulations on profitability and cost efficiency of the Islamic banks and a negative impact on conventional banks. The findings indicate that the favorable impact of Basel III on Islamic banks reduces the performance gap between both types of banks. Originality/Significance: This is perhaps the first paper which empirically explores the impact of Basel III regulations on the comparative performance of both types of banks. Policy Implications: The declining profitability and cost efficiency of conventional banks draw the attention of global and local banking regulators. Basel Committee on Banking Supervision (BCBS) and central banks of the countries with dual banking models should address this negative effect of the implementation of Basel III on conventional banks.

Purpose: To accelerate modern micro-enterprises especially for women in developing countries, waqf can bridge the gap in the financial exclusion of women in entrepreneurship activities. The goal of this research is to identify the extent to which financial inclusion can enhance women’s economic empowerment in developing countries through waqf. Methodology: This study used a desk-based review of the literature to gain insight into the concept of the research variables. Findings: The paper revealed that property waqf, cash waqf, and corporate waqf can influence women’s economic empowerment through the development of physical capital, financial capital, and human capital. Significance: This paper reviewed the extant literature to provide a research framework that will accelerate women entrepreneurship, enhance Islamic wealth management and financial inclusion of women in Muslim societies. Theoretically, this study has contributed to the body of knowledge in Islamic finance, women empowerment and entrepreneurship development. Limitations: This study only focused to the body of knowledge in women empowerment and entrepreneurship development in developing countries. Practical Implications: Practically, access to the financial system will be improved by increasing the access of small businesswomen entrepreneurs, resulting in an increase in asset ownership, wealth creation, and serving as a catalyst for larger economic empowerment. Women’s entrepreneurship in can be improved with adequate knowledge of waqf instruments, conscious planning, and implementation by relevant stakeholders.

The deinstitutionalisation of mental healthcare has left New Zealand with more voluntary community health services and an outdated and inadequate architecture for mental health. Yet mental heal this the leading cause of disability worldwide and in New Zealand alone, 1 in 6 people will suffer from some form of mental illness within their lifetime.

Mental illness is a disease that does not discriminate and yet society continues to discriminate against those who suffer from it.

This research portfolio aims to investigate the potential of architectural design in a psychiatric environment. Confronting the traumatic origins of NZ healthcare architecture it takes the site of the former Seacliff Lunatic Asylum in Dunedin, New Zealand, as the focus of its investigation. The site is revisited with a proposition for a new model for the treatment of acute mental health, addressing the shift in context and current issues in mental healthcare recovery.
