This study aimed to investigate the performance of Fcubed carocell Panel using two different types of feedwaters i.e. irrigation and brackish water. The environmental condition parameters measured consisted of Illumination, radiation, relative humidity, and temperature, while the parameters of feed water samples measured consisted of volume, temperature, and total dissolved solid of wastewater (disinfected heated water) and distilled water. The analysis showed that the distilled water yield of irrigation water was significantly different than that of brackish water. The difference was caused due to the difference content of Total Dissolved Solids and the environment’s relative humidity. The Total Dissolved Solids (TDS) of brackish water was ten times that of irrigation water, while both distilled water TDS of irrigation and brackish water were less than 10 ppm. The discharge of irrigation distilled water was relatively higher than that of brackish water. The distilled water discharge of irrigation and brackish water was 1.06 ± 0.19 l/hr and 0.86 ± 0.14 l/hr respectively. The ratio between distilled and wastewater of irrigation and brackish water were 20:1 and 25:1 respectively.- Book : 158()

Solar diffuse radiation (DIFRA) is an important component of solar radiation, but current research into the estimation of DIFRA is relatively limited. This study, based on remote sensing data, topographic data, meteorological reanalysis materials, and measured data from radiation observation stations in Chongqing, combined key factors such as the solar elevation angle, water vapor, aerosols, and cloud cover. A high-precision DIFRA estimation model was developed using the random forest algorithm, and a distributed simulation of DIFRA in Chongqing was achieved. The model was validated using 8179 measured data points, demonstrating good predictive capability with a correlation coefficient (R2) of 0.72, a mean absolute error (MAE) of 35.99 W/m2, and a root mean square error (RMSE) of 50.46 W/m2. Further validation was conducted based on 14 radiation observation stations, with the model demonstrating high stability and applicability across different stations and weather conditions. In particular, the fit was optimal for the model under overcast conditions, with R2 = 0.70, MAE = 32.20 W/m2, and RMSE = 47.51 W/m2. The results indicate that the model can be effectively adapted to all weather calculations, providing a scientific basis for assessing and exploiting solar energy resources in complex terrains.- Book : 18(4)

The hadronic vacuum polarization contribution to (g−2)μ can be determined via dispersive methods from e+e−→hadrons data. We propose a novel approach to measure the hadronic cross section σhad(s) as an alternative to the initial-state radiation and energy scan techniques, which relies on positron annihilation off atomic electrons of a high Z target (U238, Z=92). We show that by leveraging the relativistic electron velocities of the inner atomic shells, a high-intensity 12 GeV positron beam, such as the one foreseen at JLab, can allow measuring σhad(s) with high statistical accuracy from the two-pion threshold up to above s∼1 GeV.

We study the conditions for finding an island in an anisotropic universe—Bianchi type I universe filled with radiation. We verify that the existence of islands does not depend on their shape. We then find that islands may form at certain times, near the turnaround point—where the universe turns from contraction to expansion in one of the directions. This is in line with previous analyses regarding cosmological space-times where islands form if one has two energy scales in the problem, such as the typical temperature of the universe and, on top of that, cosmological constant, curvature, anisotropy, or some other mass scale.

The application of aggregation‐induced emission (AIE) materials in biological imaging holds multiple significances, including improving detection sensitivity and specificity, optimizing the imaging process, expanding the scope of application, and promoting advancements in biomedical research. In this work, the propeller ligand was constructed through McMurry coupling reaction and Suzuki coupling reaction by using dimethoxybenzophenone as the starting material. Then, an imine condensation reaction was carried out in chloroform solution, using a 3:2 molar ratio of precursor to tri(2‐aminoethyl) amine to synthesize C3 symmetric porous organic cage CB. The structures of the compounds were determined by nuclear magnetic resonance spectroscopy (NMR), electrospray ionization mass spectrometry (ESI‐MS) and Fourier transform infrared spectroscopy (FT‐IR). The optical investigation results reveal that ligand L–B and the porous organic cage CB demonstrate remarkable aggregation‐induced emission (AIE) properties in a tetrahydrofuran/water mixed solvent system, along with a pronounced response to tetrahydrofuran vapor stimuli. Consequently, Furthermore, given its unique cage‐like structure, high quantum yield, and outstanding AIE behavior, the porous organic cage CB holds promise for applications in cell imaging.- Book : ()

A giant cell tumor (GCT) of the breast is an uncommon intermediate-type soft tissue tumor with histological features resembling its osseous counterparts. To date, only 12 such cases have been documented. Our case involves a 58-year-old woman who initially presented with a breast lump progressively enlarging over six months. It was evaluated as a potential case of breast cancer. Mammography, biopsy, and, subsequently, positron emission tomography-computed tomography (PET-CT) were conducted for staging. The core biopsy specimen did not conclusively differentiate between the two suspected pathologies, i.e., GCT and Invasive breast cancer with osteoclast-like giant cells, although it was favoring the former. Following a multidisciplinary tumor board (MDTB) meeting, the patient underwent a total mastectomy and axillary lymph node dissection (TM+ALND). The large biopsy was suggestive of GCT of the breast.
We have conducted an exhaustive review of the literature on GCT of the breast, encompassing its presentation, radiological findings, differential diagnoses, and treatment modalities to formulate a structured approach for management. Additionally, we performed a statistical analysis of baseline characteristics, outcomes, and treatment modalities to succinctly summarize the current data on this subject.- Book : 11()

Abstract This study carried out a critical review of the principles of radioprotection, including the ALARA, ALADA, and ALADAIP principles. The Google Scholar and PubMed databases were the search resources, and the following keywords were searched: Linear No-Threshold (LNT); Biologic Effects of Ionizing Radiation (BEIR VII); As Low As Reasonably Achievable (ALARA); As Low As Diagnostically Acceptable (ALADA); As Low As Diagnostically Acceptable, being Indication-oriented and Patient-specific (ALADAIP). This critical review included studies with historical references, reviews, position papers, and clinical and experimental studies. Regarding data extraction, only original articles were selected after the screening process. Much of the current evolution of X-ray machines and radioprotection protocols has stemmed from legitimate concerns about this topic. This development has grown out of the relevant work of organizations like ICRP, UNSCEAR, and other renowned international organizations. Low doses of radiation, such as those used for diagnosis, also occur naturally and are present in everyday life. Although there is no agreement on the actual risk involving low doses, the recommendations of ALARA, ALADA, and ALADAIP prevail, in line with the trend to uphold principles that balance the importance of X-ray diagnostic imaging with the intention of keeping the doses as low as possible. The benefits of X-ray exams, when justified, tend to outweigh the low risks attributed to them.- Book : 39()

In this study, we tested the overall hypothesis that CC expansion and early embryo development would be improved by including follicular fluid (FF) from small or large follicles in the oocyte maturation medium. In the first experiment, FF aspirated from bovine abattoir ovaries was added to the maturation medium at 0, 25, 50, 75 or 100%. Images of individual COCs were captured at 0, 6, 12 and 19 hours (h) of the maturation period and analyzed to calculate change in the total area over time. Cumulus cell expansion was greatest in COCs matured in 75% and 50% FF, and these differences were detectable at 12 (75% FF only) and 19 h (50% and 75% FF) of maturation. The improvement in CC expansion was greatest when FF from small follicles was used. Treatments for the subsequent experiments were selected based upon the results of the first experiment. Oocyte nuclear maturation rates were observed after supplementing the maturation medium with 0 or 75% FF and maturing for 19 h. The rate of nuclear maturation as determined by the presence or absence of the first polar body was similar between control (0% FF) and treated (75% FF) groups. In the final experiment, COCs were matured in 0%, 50% or 75% FF in preparation for IVF. Duration of the maturation period (12, 19 or 22 h) and size of the follicles from which FF was collected (small or large) also varied. In general, FF supplementation at 50% did not affect the zygotes’ developmental potential (neither increased nor decreased). Supplementation of maturation medium with 75% FF from small follicles consistently reduced measures of embryo development while 75% FF from large follicles yielded mixed results. It is concluded that FF supplementation improves CC expansion, but the greater CC expansion does not benefit subsequent embryo development. Notably, however, the 50% FF treatment did not reduce blastocyst rates, indicating that FF can be included in maturation media at concentrations of 50% or less with no detriment to IVF outcomes.- Book : 20(2)

Oxide-dispersion-strengthened (ODS) alloys exhibit exceptional mechanical properties, making them ideal for high-temperature applications in areas such as aerospace and nuclear reactors. The traditional manufacturing of ODS alloys involves mechanical alloying, followed by processes such as hot extrusion and hot isostatic pressing. However, these methods are limited when it comes to producing complex geometries. Recent advances in additive manufacturing (AM) techniques, specifically selective laser melting (SLM) and directed-energy deposition (DED), offer exciting new possibilities for fabricating ODS alloys. Early research demonstrated the feasibility of using SLM to create complex parts with uniformly dispersed oxide particles, thereby enhancing the materials’ properties. Subsequent studies confirmed that optimising the SLM parameters could further improve the mechanical performance of ODS alloys. DED techniques have also shown promise, with innovations like in-situ oxide formation during deposition and high-speed laser cladding. These methods have achieved success by producing ODS materials with refined microstructures and enhanced mechanical properties. The latest research continues to explore the potential of AM for ODS alloys, focusing on improving the dispersion of nanoparticles and minimising the tendency of particles to agglomerate. Overall, AM has advanced the fabrication of ODS alloys by offering efficient production routes and the ability to create intricate designs with superior properties.- Book : 59(1)
