Abstract
The 1998 monetary crisis that hit Indonesia encouraged people to look for other economic alternatives, namely the sharia economy. However, the practice of Islamic economics in Indonesia is still thick with conventional economic practices, especially those found in Islamic financial institutions or Islamic banking. This study uses a qualitative research method to examine the literature to examine how the practice of Islamic economics in Islamic banking in Indonesia. The results show that the practice of sharia sharia economics, namely murabahah, the application of fines, and the use of contracts in Islamic banks in Indonesia is still far from the principles of Islamic law, and is supported by sharia economic regulators who misinterpret the implementation of sharia economics.

Aims: This study was aimed at investigating the protective potential of ethyl acetate fractions of Persea americana (PA) seed and Bryophyllum pinnatum (BP) leaf binary combinations against indomethacin-induced gastric ulcers.
Methodology: Fifty (50) male Wistar rats were used in this study; they were assigned into 10 groups of five animals each and respective groups received a standard rat diet and drinking water ad libitum. The groups were group 1 (normal control group (NC)), group 2 (ulcer control (UC)), group 3 (Omeprazole, 20mgkg-1 (OMEP)), group 4 (PA) and group 5 (BP). Groups receiving binary combinations were group 6 (PA + BP, 1:1), group 7 (PA + BP, 1:2), group 8 (PA + BP, 1:3), group 9 (PA + BP, 2:1), group 10 (PA + BP, 3:1) each group was pre-treated with 400 mgKg-1 body weight/day of respective fraction or binary mixture by intubation for 21 days. On the 22nd day after overnight fasting, a gastric ulcer was induced with indomethacin (30mg/kg body weight) by intubation in a single dose. Ulcer markers and histopathology of stomach tissues were measured using standard methods.
Results: The present study revealed that the ethyl acetate fraction of the plants PA seeds and BP leaf showed potent gastric tissue protective effects. Analysis of gastric changes indicated a significant (P<0.05) reduction in ulcer index, gastric acid output, gastric mucus content and pepsin activity of ulcerated rats pretreated with PA and BP fractions. The effect of the binary combinations was significantly (p<0.05) higher than single plant fractions. The protective effect of the fractions was in the order OMEP > PA+BP (3:1) > PA+BP (2:1) > PA+BP (1:1), > PA+BP (1:2) > PA+BP (1:3) > PA > BP. The observed ulcero-protective effect of the binary combinations of P. americana seed and B. pinnatum leaf may be attributed to the synergy of the phytochemicals contained in the fractions.
Conclusion: These findings suggest that P. americana and B. pinnatum ethyl acetate fraction combination favorably protect against indomethacin-induced gastric mucosal oxidative damage, reducing ulcer index, gastric acid output, gastric mucus content and pepsin activity. The ethyl acetate fractions exhibited a dose-dependent inhibition of ulcer formation in indomethacin gastric ulcer model.

Published: December 2022

Efficient wastewater treatment technologies are needed to curb water scarcities and prevent the spread of diseases and contamination of water sheds. Decentralized wastewater treatment systems or respectively septic systems are easy to afford and handle – especially in rural areas. In this research a developed 19.9 l (5 gal.) laboratory septic system containing 15 l (3.96 gal.) of liquid was operated at a temperature of 18°C (64.4°F) with wastewater collected from a primary clarifier of a local wastewater treatment plant. The laboratory study included a hydraulic retention time of 30-, 10- and 5-day with and without addition of bacteria from an anaerobic sludge blanket reactor and commercially available bacteria for enhancement of septic systems.
Operating the laboratory septic system at a 10-day HRT showed the best performance for all system operations with and without enhancement bacteria in comparison n to 30- and 5-day HRT.
The developed laboratory septic system proved to be a valuable way to investigate septic systems performance on a laboratory scale.

Published: December 2022

The population of women contributes nearly half of the total count but it counts for only a quarter of total workforce participation in India. The participation of women in different workforces is not only limited to the financial need of the family but is also related to the social system, the education level of the women, and the availability of work opportunities for them. The present study aims to compare the sector-specific women's work participation level and associated social factors of the women workforce. Two regions out of five regions in West Bengal specified by NSSO were considered to be study regions. Incorporating the necessary variables, a structured interview schedule was prepared and data were collected from randomly selected 160 working women from two districts from two regions under study. The collected data has been finalized for analysis after a validity check. Necessary frequency analysis and non-parametric tests have been performed to get the results.
Most of the respondents of central regions were service holders. Education has a signification effect on income level in both the regions under study. Service holders were at significantly higher income levels than other occupational groups. The respondents from the central regions were more educated and empowered than the women of the western region. A large scale of variety in occupational involvement has been found in both regions in the present study. The income level is directly related to occupation and education. The educated women of both regions preferred service as their occupation and earn more than other categories. Specific policies or programs that enhance institutional involvement of all occupational categories may cater to our developmental goal.

Published: December 2022

AbstractPurposeEstablish a workflow to evaluate radiotherapy (RT) dose variation induced by respiratory and cardiac motion on the left ventricle (LV) and left ventricular myocardium (LVM).MethodsEight lung cancer patients underwent 4D‐CT, expiratory T1‐volumetric‐interpolated‐breath‐hold‐examination (VIBE), and cine MRI scans in expiration. Treatment plans were designed on the average intensity projection (AIP) datasets from 4D‐CTs. RT dose from AIP was transferred onto 4D‐CT respiratory phases. About 50% 4D‐CT dose was mapped onto T1‐VIBE (following registration) and from there onto average cine MRI datasets. Dose from average cine MRI was transferred onto all cardiac phases. Cumulative cardiac dose was estimated by transferring dose from each cardiac phase onto a reference cine phase following deformable image registration. The LV was contoured on each 4D‐CT breathing phase and was called clinical LV (cLV); this structure is blurred by cardiac motion. Additionally, LV, LVM, and an American Heart Association (AHA) model were contoured on all cardiac phases. Relative maximum/mean doses for contoured regions were calculated with respect to each patient's maximum/mean AIP dose.ResultsDuring respiration, relative maximum and mean doses on the cLV ranged from −4.5% to 5.6% and −14.2% to 16.5%, respectively, with significant differences in relative mean doses between inspiration and expiration (P < 0.0145). During cardiac motion at expiration, relative maximum and mean doses on the LV ranged from 1.6% to 59.3%, 0.5% to 27.4%, respectively. Relative mean doses were significantly different between diastole and systole (P = 0.0157). No significant differences were noted between systolic, diastolic, or cumulative cardiac doses compared to the expiratory 4D‐CT (P > 0.14). Significant differences were observed in AHA segmental doses depending on tumour proximity compared to global LV doses on expiratory 4D‐CT (P < 0.0117).ConclusionIn this study, the LV dose was highest during expiration and diastole. Segmental evaluation suggested that future cardiotoxicity evaluations may benefit from regional assessments of dose that account for cardiopulmonary motion.

AbstractThis prospective study sought to evaluate potential savings of radiation dose to medical staff using real‐time dosimetry coupled with visual radiation dose feedback during angiographic interventions. For this purpose, we analyzed a total of 214 angiographic examinations that consisted of chemoembolizations and several other types of therapeutic interventions. The Unfors RaySafe i2 dosimeter was worn by the interventionalist at chest height over the lead protection. A total of 110 interventions were performed with real‐time radiation dosimetry allowing the interventionalist to react upon higher x‐ray exposure and 104 examinations served as the comparative group without real‐time radiation monitoring. By using the real‐time display during interventions, the overall mean operator radiation dose decreased from 3.67 (IQR, 0.95–23.01) to 2.36 μSv (IQR, 0.52–12.66) (−36%; p = 0.032) at simultaneously reduced operator exposure time by 4.5 min (p = 0.071). Dividing interventions into chemoembolizations and other types of therapeutic interventions, radiation dose decreased from 1.31 (IQR, 0.46‐3.62) to 0.95 μSv (IQR, 0.53‐3.11) and from 24.39 (IQR, 12.14‐63.0) to 10.37 μSv (IQR, 0.85‐36.84), respectively, using live‐screen dosimetry (p ≤ 0.005). Radiation dose reductions were also observed for the participating assistants, indicating that they could also benefit from real‐time visual feedback dosimetry during interventions (−30%; p = 0.039). Integration of real‐time dosimetry into clinical processes might be useful in reducing occupational radiation exposure time during angiographic interventions. The real‐time visual feedback raised the awareness of interventionalists and their assistants to the potential danger of prolonged radiation exposure leading to the adoption of radiation‐sparing practices. Therefore, it might create a safer environment for the medical staff by keeping the applied radiation exposure as low as possible.

AbstractWound infection is arguably the most common, and potentially the most devastating, complication of the wound healing process. The ideal treatment strategy has to eliminate bacteria, alleviate inflammation, and promote wound healing and skin formation. Herein, a multifunctional heterostructure is designed consisting of ultrasmall platinum–ruthenium nanoalloys and porous graphitic carbon nitride C3N5 nanosheets (denoted as PtRu/C3N5), which concurrently possesses piezoelectric enhanced oxidase ‐mimic nanozyme activity and photocatalytic hydrogen gas production capacity. Moreover, these hybrid nanotherapeutics are integrated in natural hyaluronic acid microneedles, which exhibit almost 100% broad‐spectrum antibacterial efficacy against multiple bacterial strains in vitro and in vivo within 10 min ultrasound treatment, and effectively inhibit inflammation reactions after 1 h visible light irradiation, promising for accelerating the cutaneous wound healing in the bacterial infected mice. This study highlights a competitive strategy for development of all‐in‐one antibacterial and anti‐inflammatory therapies.

Published: December 2022

AbstractThe resource scarcity and high cost seriously hamper the large‐scale application of platinum to catalyze the hydrogen evolution reaction (HER). An extraordinarily efficient single‐layer Pt (SL‐Pt) cluster catalyst is synthesized by a facile photolysis‐electroreduction method. Electron microscopy and atomic force microscopy images demonstrate the single‐layer structure with a thickness of ≈0.3 nm. Density functional theory calculations reveal that the charge is redistributed in the SL‐Pt cluster, which yields a downshift in d‐band center of Pt 5d orbital. The above two features of the SL‐Pt cluster yield a high atomic utilization and superior intrinsic activity when used as the electrocatalyst. As a result, the electrochemical test reveals its mass activity of the HER is two orders of magnitude higher than the commerical Johnson–Matthey 20 wt.% Pt/C. As demonstration, the SL‐Pt cluster exhibits a low electrolysis voltage of ≈1.74 V at 1.0 A cm−2 with superior stability up to 48 h in a single‐cell proton exchange membrane water electrolyzer. This study does not only provide a facile method to prepare single‐layer metal cluster, but also provides a stable HER's catalyst for efficient water splitting.

Published: December 2022

AbstractOxidative stress is a cause for numerous diseases and aging processes. Thus, researchers are keen to tune the level of intracellular stress and to learn from that. An unusual approach is presented here. The methodology involves multifunctional surfactants. Although their molecular design is nonbiological—a fullerenol head group attached covalently to pi‐conjugated dyes—the surfactants possess superior biocompatibility. Using an intrinsic fluorescence signal as a probe, it is shown that the amphiphiles become incorporated into the Caco‐2 cells. There, they are able to exhibit additional functions. The compound reduces cellular stress in dark reaction pathways. The antagonistic property is activated under irradiation, the photocatalytic production of reactive oxygen species (ROS), resulting in cell damage. The feature is activated even by near‐infrared light (NIR‐light) via a two‐photon process. The properties as molecular semiconductors lead to a trojan horse situation and allows the programming of the spatial distribution of cytotoxicity.

Published: December 2022

AbstractCytophilic (cell‐adhesive) materials are very important for tissue engineering and regenerative medicine. However, for engineering hierarchically organized tissue structures comprising different cell types, cell‐specific attachment and guidance are decisive. In this context, materials made of recombinant spider silk proteins are promising scaffolds, since they exhibit high biocompatibility, biodegradability, and the underlying proteins can be genetically functionalized. Here, previously established spider silk variants based on the engineeredAraneus diadematusfibroin 4 (eADF4(C16)) are genetically modified with cell adhesive peptide sequences from extracellular matrix proteins, including IKVAV, YIGSR, QHREDGS, and KGD. Interestingly, eADF4(C16)‐KGD as one of 18 tested variants is cell‐selective for C2C12 mouse myoblasts, one out of 11 tested cell lines. Co‐culturing with B50 rat neuronal cells confirms the cell‐specificity of eADF4(C16)‐KGD material surfaces for C2C12 mouse myoblast adhesion.

Published: December 2022

AbstractConformal artificial electromagnetic media that feature tailorable responses as a function of incidence wavelength and angle represent universal components for optical engineering. Conformal grayscale metamaterials are introduced as a new class of volumetric electromagnetic media capable of supporting highly multiplexed responses and arbitrary, curvilinear form factors. Subwavelength‐scale voxels based on irregular shapes are designed to accommodate a continuum of dielectric values, enabling the freeform design process to reliably converge to exceptionally high figures of merit (FOMs) for a given multi‐objective design problem. Through additive manufacturing of ceramic–polymer composites, microwave metamaterials, designed for the radio‐frequency range of 8–12 GHz, are experimentally fabricated and devices with extreme dispersion profiles, an airfoil‐shaped beam‐steering device, and a broadband, broad‐angle conformal carpet cloak, are demonstrated. It is anticipated that conformal volumetric metamaterials will lead to new classes of compact and multifunctional imaging, sensing, and communications systems.
