Utilization of Sargassum Flour Fermented with Bacillus aerius Bacteria in Siganus guttatus Rabbitfish Enlargement Feed

This Sargassum is a staple food of rabbitfish in nature; although its nutritional quality is relatively low if it is used as one of the feed ingredients first carried out in the fermentation process, the results of this fermentation are used as one of the raw feed materials. The study was conducted to look at the use of fermented sargassum flour in feed at the lowest dose of 7.5% to the highest dose of 30%. This study was designed using a completely randomized design (RAL). Using 15 units of floating net cage containers. The study duration was 120 days. During the study, the test fish were fed thrice daily, namely 08.00 am, 1:00 pm, and 03:00 pm. Feeding is carried out. To determine the severity of the treatment of the biological response of test fish, sampling is carried out every 30 days. From several parameters observed, such as weight gain, specific growth rate, and daily feed consumption rate, although statistically not different (P>0.05), the tendency to increase with the increase in sargassum dose by 30%. Similarly, the total digestibility of feed, digestibility of feed protein, and digestibility of feed energy statistically do not show a difference (P>0.05) but also the tendency to increase. Based on the results of this activity, it was concluded that sargassum flour that has been fermented with bacillus aerius bacteria can be used well by rabbitfish, with as much as 30% in the feed.
Structural and Functional Strategies in Cenchrus Species to Combat Environmental Extremities Imposed by Multiple Abiotic Stresses

Multiple abiotic stresses such as drought, salinity, heat, and cold stress prevailing in natural habitats affect plant growth and development. Different species modify their structural and functional traits to combat these abiotic stresses while growing in stressful environments. Cenchrus species, i.e., Cenchrus pennisetiformis, C. setiger, and C. prieurii are widely distributed grasses found growing all over the world. Samples from natural populations were collected from different ecological regions in the Punjab and Khyber Pakhtoonkhwa that were exposed to aridity, salinity, and cold, while one site was designated as normal control. In the present study, structural and functional modifications of three Cenchrus species under abiotic stresses were evaluated. It was expected that each Cenchrus species may evolve different strategies to cope with multiple abiotic stresses. All Cenchrus species responded differently whether growing in normal environment or stressful conditions. The most remarkable feature for survival in C. pennisetiformis under cold stress was increased inflorescence and increased stem and root lignification. C. prieurii showed better tolerance to saline and cold environments. C. setiger showed better development of leaf sheath anatomical traits. The structural and functional modifications in Cenchrus species such as development of mechanical tissues provided structural support, while dermal and parenchymatous tissues increased water storage capacity and minimized water loss. An increase in the concentration of organic osmolytes and ionic content aids turgor pressure maintenance and ionic content crucial for plant growth and development. It was concluded that structural and functional alterations in all Cenchrus species were very specific and critical for survival under different environmental stresses. The ecological fitness of these species relied on maintenance of growth and biomass production, and the development of mechanical, vascular, dermal and parenchyma tissues under stressful environmental conditions. Moreover, accumulation of beneficial ions (K+ and Ca2+) and organic osmolytes were critical in turgor maintenance, hence survival of Cenchrus spp.
U-Pb zircon ages of rocks from the Amazonas Territory of Colombia and their bearing on the tectonic history of the NW sector of the Amazonian Craton

Here we report the results of several U-Pb zircon ages, made to generate an integrated history for the Rio Negro-Juruena tectonic province, for the northwestern part of the Amazonian ­Craton. This region comprises granitoid rocks, described as calc-alkaline syntectonic gneisses, granites and migmatites, affected by medium level amphibolite facies metamorphism. The new measurements, with the available Rb-Sr and K-Ar ages, indicate the formation of these rocks within a series of essentially juvenile magmatic arcs, that are closely related with subduction. Sm-Nd analyses indicate that all samples, regardless of their zircon ages, yielded TDM model ages roughly between 1.9 and 2.2 Ga, suggesting the absence of a much older source material. In the northeastern part (areas of Puerto Inirida and San Carlos), the Atabapo belt comprises rocks formed within a period of about 60 Ma, from 1800 to 1740 Ma. In the southwestern region, including the towns of Mitu and Iauarete, the granitoids formed in the Vaupes belt between 1580 and 1520 Ma. Finally, the available K-Ar measurements indicate the onset of the Nickerie-K'Mudku intraplate heating event, with temperature above 300oC within the entire region at 1200 - 1300 Ma.
The Relationship between Mathematics Teachers’ TPACK and Students' Mathematical Resilience

Previous research shows that teachers play a role in determining students' math resilience. However, there is still little research on the type of teacher competencies that support students' mathematical resilience. This study examines the effect of mathematics teachers’ Technological Pedagogical Content Knowledge (TPACK) on students' math resilience. This quantitative study involved 163 students from a junior high school and four senior high schools in the East Kalimantan region. Data was collected through questionnaires that measured mathematics teachers' TPACK from the student perspective and students’ math resilience. Information about the gender of respondents is also collected. Data were analyzed using multiple linear regression and moderated regression. The results exposed that the mathematics teachers’ TPACK significantly affected students' math resilience. The components of Pedagogical Knowledge and Technological Pedagogical Content Knowledge partially affect students' math resilience. However, the study found no moderation by student gender on the relationship between mathematics teachers' TPACK and students' math resilience. This study contributes significantly to understanding the role of mathematics teachers' TPACK in improving students' math resilience. The results can be a reference for related parties, especially in developing more effective mathematics teacher training and competency development programs.
High precision performance evaluation for digital radiography detectors

Performance of digital radiography detectors can be evaluated from measuring the noise power spectrum (NPS), modulation transfer function, and detective quantum efficiency (DQE). Hence, measuring these quantities with high precisions is important. In this paper, to measure the quantities, we introduce a program, which is called DRDQE (digital radiography DQE). DRDQE supports the IEC62220 standards for various radiography detectors. Furthermore, DRDQE can measure NPS and DQE with high precisions based on Small-Subimage Algorithm. Compensated Partial-Sum Algorithm is also adopted to measure a high-precision NPS at zero frequency. We briefly introduce the employed algorithms in DRDQE and then show an example of DRDQE usage for a direct flat-panel mammography detector. The high-precision measurements from DRDQE were compared with the IEC62220 standard.
Dynamical Downscaling of SINTEX-F2v CGCM Seasonal Retrospective Austral Summer Forecasts over Australia

AbstractAn ensemble of 1-month-lead seasonal retrospective forecasts generated by the Scale Interaction Experiment (SINTEX)–Frontier Research Center for Global Change (FRCGC), version 2 tuned for performance on a vector supercomputer (SINTEX-F2v), coupled global circulation model (CGCM) were downscaled using the Weather Research and Forecasting (WRF) Model to improve the forecast of the austral summer precipitation and 2-m air temperatures over Australia. A set of four experiments was carried out with the WRF Model to improve the forecasts. The first was to drive the WRF Model with the SINTEX-F2v output, and the second was to bias correct the mean component of the SINTEX-F2v forecast and drive the WRF Model with the corrected fields. The other experiments were to use the SINTEX-F2v forecasts and the mean bias-corrected SINTEX-F2v forecasts to drive the WRF Model coupled to a simple mixed layer ocean model. Evaluation of the forecasts revealed the WRF Model driven by bias-corrected SINTEX-F2v forecasts to .
Helicobacter Pylori Infection as A Risk Factor for Colorectal Cancer

Background: Helicobacter pylori (HP) infection, traditionally associated with gastric disorders, has increasingly drawn attention for its potential role in extra-gastric pathologies. Colorectal cancer (CRC) is among the diseases under scrutiny, with emerging evidence suggesting a possible link between HP infection and CRC risk. Objective: This study aimed to assess the correlations between H. pylori infection and colorectal cancer. Subjects and methods: A total of 85 individuals were recruited from the Internal Medicine Department of Benha University Hospital through the period from January 2023 to July 2023 and categorized into two groups. Group 1 consisted of 50 patients with confirmed CRC following colonoscopy and histopathological examination. Group 2, the control group, included 35 individuals without CRC. Both inpatients and outpatients aged 18-70 years of both sexes. Results: patients with CRC were older and had lower hemoglobin levels, higher leukocyte counts, and elevated urea, creatinine, and international normalized ratio (INR) compared to controls. However, there were no significant gender differences. When categorized by H. pylori stool antigen presence, no age, gender, or laboratory parameter differences emerged between those with positive and negative antigen status. Notably, multivariate analysis revealed a substantial association between H. pylori stool antigen positivity and a nearly tenfold increased risk of CRC, even after adjusting for age and gender, highlighting the potential link between H. pylori infection and CRC in this study population. Conclusions: The present study confirmed the predictor value of positive stool antigen for H. pylori infection for development of colorectal cancer.
A Study on Employee Retention among Millennials in Malaysia

Employee turnover, especially among millennials, has become a phenomenon and a significant concern to the organisation as the trend has increased over the years. Hence, the organisation needs to understand them and address employee turnover among millennials. Drawing on Malaysia as a case study, this study examines different approaches to retaining millennials in the workforce regarding work attitude (career development, work-life balance, and job security) to help millennials integrate and retain them. A questionnaire was administered to 384 respondents in private sector employees and analysed using the Statistical Package for the Social Sciences (SPSS). The survey results revealed that promotion, work-life balance, and job security positively correlate with employee retention. Given the findings, this study addresses the approach to employee retention effects for theory and practice in managing human resources in organisation. The findings can be applied to other developing countries with similar characteristics to understand their millennials
Spatial Patterns and Frequency of Unforced Decadal-Scale Changes in Global Mean Surface Temperature in Climate Models

AbstractThe causes of decadal time-scale variations in global mean temperature are currently under debate. Proposed mechanisms include both processes internal to the climate system as well as external forcing. Here, the robustness of spatial and time scale characteristics of unforced (internal) decadal variability among phase 5 of the Coupled Model Intercomparison Project (CMIP5) preindustrial control runs is examined. It is found that almost all CMIP5 models produce an interdecadal Pacific oscillation–like pattern associated with decadal variability, but the frequency of decadal-scale change is model dependent. To assess the roles of atmosphere and ocean dynamics in producing decadal variability, two preindustrial control Community Climate System model (version 4) configurations are compared: one with an atmosphere coupled to a slab ocean and the other fully coupled to a dynamical ocean. Interactive ocean dynamics are not necessary to produce an IPO-like pattern but affect the magnitude and frequency of .
Strength and Chemical Characterization of Ultra High-Performance Geopolymer Concrete: A Coherent Evaluation

The objective of this review article is to analyze published data encompassing compressive strength, tensile strength, elastic modulus, and flexural strength, as well as the utilization of scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDS), and x-ray diffraction (XRD) for Ultra High-Performance Geopolymer Concrete (UHP-GC), with the focus of establishing the current research trends regarding its mechanical, microstructural, and chemical characteristics. After a critical evaluation of the published data from the literature findings, it became evident that UHP-GC can attain a remarkably high level of engineering performance. In UHP-GC, the optimum percentage of silica fume as a slag partial replacement to achieve high compression, tensile, and elastic modulus were traced to be 25, 30, and 35%, respectively. The optimum ratio of sodium silicate to sodium hydroxide and sodium hydroxide molarity for UHP-GC were identified to be 3.5 and 16, respectively. All in all, the review provides a thorough understanding of the review gap and distinct functions of different raw materials in decreasing porosity and enhancing the formation of geopolymeric gels that not only bond but also strengthen UHP-GC. UHP-GC stands as an energy-saving material in concrete technology, poised to forge a path towards a sustainable future for the building sector. Doi: 10.28991/CEJ-2023-09-12-020 Full Text: PDF
Multi‐scale classification of fluvial architecture: An example from the Palaeocene–Eocene Bighorn Basin, Wyoming

Fluvial channel geometry classification schemes are commonly restricted in relation to the scale at which the study took place, often due to outcrop limitations or the need to conduct small‐scale detailed studies. A number of classification schemes are present in the literature; however, there is often limited consistency between them, making application difficult. The aim of this study is to address this key problem by describing channel body geometries across a depositional basin to ensure that a wide range of architectures are documented. This was achieved by studying 28 locations over 4000 m of vertical succession in Palaeocene‐aged and Early Eocene‐aged deposits within the Bighorn Basin, Wyoming, USA. Five different channel body geometries have been defined based on the external geometric form, and internal arrangement and nature of storey contacts. These include the massive channel body geometry, semi‐amalgamated channel body geometry, internally amalgamated channel body geometry and offset stacked channel body geometry, which are considered to be subdivisions of the sheet geometry of many other classifications. An isolated channel body geometry has also been recognized alongside splay channel and sheet sandstone geometries in the floodplain facies associations. Field evidence, including the stacking style of storey surfaces, suggests that the different geometries form a continuum. The nature and degree of amalgamation at the storey scale are important in producing the different geometries and are related to the degree of channel migration. It is speculated that this is the result of differences in sediment supply and available accommodation. In contrast to previous schemes, the classification scheme presented here recognizes the importance of transitional geometries. This geometrical range has been recognized because of the basin‐scale nature of the study.
Conceptual Application of Biological Removal of Toxic Metals: in Situ Cr(vi) Reduction

This study addresses the problem of Cr(VI) pollution at chrome processing foundries in South Africa. A novel culture was isolated from a local treatment works in the North West Province. The isolated culture performed better than cultures previously isolated in the United States. Up to 200 mg Cr(VI)/L was completely removed after incubation in batch studies for about 64.5 hours. This high performing Cr(VI) reducing microorganism is used to develop an environmentally friendly in situ bioremediation process involving the design of a biological permeable reactive barrier (BPRB) for a Cr(VI) contaminated site at Brits, (South Africa).
Students' perceptions of an agricultural communications field trip

This mixed-method research describes student perceptions of a collegiate agricultural communications course field trip to employers in journalism-related fields in a major metropolitan area. The trip provided an effective educational method related to enhancing students’ perceptions of a broad communications-related skillset. However, the researchers found students may have trouble transitioning between the classroom and real-world newsroom and office settings. Students may also have trouble connecting their agricultural communications skillset to non-food and fiber industries.
Mechanical properties of the rabbit and human decellularized patches for well-tolerated/reinforced organ in cardiac tissue engineering

Introduction: Natural decellularized patches have been developed as the therapeutic platform for the treatment of different diseases, especially cardiovascular disorders. Decellularized scaffolds (as both cell-seeded and cell-free patches) are broadly studied in heart tissue redevelopment in vivo and in vitro. The designed regenerative bio-scaffold must have desirable physicochemical properties including mechanical stiffness for load-bearing, and appropriate anatomical characteristics to mimic the native biological environment properly and facilitate tissue reconstruction. In this context, the current study was designed to investigate rabbit decellularized derma’s similarity with human decellularized skin in terms of mechanical properties for cardiac tissue engineering application. Methods: Fifty two rabbit dermal specimens were provided and divided into two groups: the experimental (decellularized) group and the control (group). Similarly, twelve human skin specimens were divided into the experimental (decellularized) and control groups. Initially, the effect of decellularization on the mechanical performance of scaffolds was analyzed. Then, the mechanical strength of decellularized rabbit skin was compared to decellularized human derma by measuring the stress strain and Young’s modulus of the samples. Results: The results showed that rabbit decellularized skin has a similar elastic range to human decellularized skin, despite being more elastic (P>0.05). In addition, after decellularization, both rabbit and human skin showed a non-significant decrease in elasticity (P>0.05). It is worth noting that the elasticity reduction in rabbit samples after skin decellularization was lower than in human samples. Conclusion: According to the results of this study and the similarities of rabbit decellularized derm to human skin and its advantages over it, along with the biological complexity of native cardiac ECM, this scaffold can be used as an alternative matrix for tissue-engineered cardiac patches.
Insomnia and the menopause: Where are we and where are we going?

The menopause, marked by a decrease in ovarian follicles and changes in female sex hormones, can trigger symptoms such as facial flushing and sleep disturbances. Hormonal fluctuations, notably a decrease in estrogen and progesterone, are associated with night-time awakenings and difficulty maintaining uninterrupted sleep. This condition has a negative impact on quality of life, leading to conditions such as obesity, diabetes, cardiovascular disease, and depression. The transition to menopause intensifies sleep disorders, especially insomnia, which is often associated with hot flashes. Despite the lack of clear evidence on the efficacy of hormone therapy, its use persists, highlighting the need for personalized approaches. Therapeutic strategies, such as the fusion of hormone therapy with sleep hygiene and cognitive-behavioral therapy, are emerging as promising. Some recommendations include adjustments to sleep habits, regular exercise, and a balanced diet. In conclusion, menopause significantly influences sleep disorders in women, affecting various aspects of physical and emotional health. Comprehensive therapeutic strategies, including behavioral changes, hormone therapy, and nutritional support, show promise for improving quality of life during this inevitable transition in female aging.
A New LA‐ICP‐MS Method for Ti in Quartz: Implications and Application to High Pressure Rutile‐Quartz Veins from the Czech Erzgebirge

Experimental determination of the pressure and temperature controls on Ti solubility in quartz provides a calibration of the Ti‐in‐quartz (TitaniQ) geothermometer applicable to geological conditions up to ~ 20 kbar. We present a new method for determining 48Ti mass fractions in quartz by LA‐ICP‐MS at the 1 μg g−1 level, relevant to quartz in HP‐LT terranes. We suggest that natural quartz such as the low‐CL rims of the Bishop Tuff quartz (determined by EPMA; 41 ± 2 μg g−1 Ti, 2s) is more suitable than NIST reference glasses as a reference material for low Ti mass fractions because matrix effects are limited, Ca isobaric interferences are avoided, and polyatomic interferences at mass 48 are insignificant, thus allowing for the use of 48Ti as a normalising mass. Average titanium mass fraction from thirty‐three analyses of low temperature quartz from the Czech Erzgebirge is 0.9 ± 0.2 μg g−1 (2s) using 48Ti as a normalising mass and Bishop Tuff quartz rims as a reference material. The 2s average analytical uncertainty for individual analyses of 48Ti is 8% for 50 μm spots and 7% for 100 μm spots, which offers much greater accuracy than the 21–41% uncertainty (2s) incurred from using 49Ti as an analyte.
