With regard to moment-resistant frames composed of CFT (concrete-filled tube) columns, H-shaped beams and diagonal braces, the strong axial force of a diagonal brace firstly transfer to the steel tubular portion of a column at beam-to-column connection and then to the filled concrete. Two types of stress transfer mechanisms from steel portion to the filled concrete may be available in CFT columns. The one is the concrete bond in a steel tube, and the other is a mechanical shear key effect functioned by the cut-through diaphragms which are often used for a beam-to-column connection in Japan. However, either of the mechanisms have not been demonstrated by realistic frame assembly specimens so far. Such a lack of the information is now causing the over-safety design for the stress transfer in a connection especially installed by diagonal braces. From this point of view, we performed a horizontal loading test of CFT frame assemblies, and discussed the stress transfer effects for both mechanisms.

The separate collections of Heteroptera (Insecta, Hemiptera) preserved in the Muséum national d'Histoire naturelle (Paris). One of the peculiarities of the insect collections of the Muséum national d'Histoire naturelle (MNHN) in Paris is to have preserved, in many orders, quantity of private collections, also called “nominal collections”, next to the general collection. Over the course of two centuries (19th and 20th) and right up today, these collections, acquired by donation, bequest or purchase, have enriched the national collections, and many have remained in their original state. At the request of several French and foreign colleagues, and in response to frequently-asked questions, we present here an annotated inventory of the 32 private collections of Heteroptera currently separated from the general collection. For each of them, we give biographical details about the author, as well as the following information: state of the collection, presence of typical material, scientific interest and, where applicable, historical interest. Details are also given on the specimens from three dismantled old collections (Bosc d'Antic, Fieber and Lethierry), now scattered throughout in the general collection, or in other private collections. In addition, information is provided on the old general collection of Heteroptera collection created at MNHN during the 19th century and kept separately from the current general collection under the name of “Collection Amyot & Serville”. This inventory highlights an all-too-often forgotten fact: having a collection in its original state is always a rich source of information, and dismantling it is an irretrievable loss of information.

This study investigated how shared socioeconomic pathways (SSPs) scenarios affect farmland soil organic carbon (SOC). The effects of historical precipitation, temperature, soil type, soil features, land shape, farming methods, and land use changes on SOC trends from 1982 to 2024 were examined in Karvir area Maharashtra, India. Predictions used machine learning modelers Random Forest (RF), Extreme Gradient Boosting (XGB) and Support Vector Regression (SVR). Coefficient of determination (R2), mean error (ME), and root mean square error (RMSE) were optimal for XGB at 0.998, 0.000, and 0.225g/kg, respectively. Using remote sensing data processed in Google Earth Engine (GEE) and Geographic Information System (GIS), the model was validated by a certified local soil testing laboratory, achieving an R² of 0.88, an RMSE of 1.9g/kg, and an ME of 1.5g/kg. Temperature and rainfall under high SSPs drastically reduced projected SOC. In the worst case (SSP5-8.5), the mean SOC in 2040 declined from 46.4 to 24.2g/kg in 2100. Since 2018, conservation agricultural technologies like no-till farming, mulching, and composting have boosted SOC while farmland has decreased over 42 years. These findings give a paradigm for climate-adaptive management alternatives that promote SOC sequestration, soil health, and sustainable agriculture.

This study examines the economic impact of social media marketing (SMM) on corporate value creation through a comprehensive analysis ‎of 450 publicly traded companies across multiple industries from 2018 to 2023. Using a mixed-methods approach combining quantitative ‎financial and qualitative content analysis, we investigate how social media marketing investments translate into measurable corporate value. ‎Our findings reveal that companies with strategic social media marketing initiatives demonstrate significantly higher market valuations, with ‎an average 12.3% increase in enterprise value compared to firms with minimal social media presence. The study employs multiple ‎regression analysis, event study methodology, and propensity score matching to establish causal relationships between SMM expenditures ‎and key financial performance indicators, including ROI, brand equity, and shareholder value. Results indicate that social media marketing ‎effectiveness varies significantly across industries, with technology and consumer goods sectors showing the highest correlation ‎coefficients (r = 0.742 and r = 0.689, respectively). The research contributes to the growing literature on digital marketing's financial impact ‎by providing empirical evidence of SMM's role in value creation mechanisms. Practical implications suggest that optimal SMM investment ‎levels range between 2.5-4.2% of total marketing budget for maximum value creation efficiency. This study advances our understanding of ‎digital marketing's economic implications and provides actionable insights for corporate financial strategy in the digital economy‎.

Plant growth stimulants like humic acid had led to an intense interest due to having beneficial influences on different crops. The primary constituents of humic matter tend to be humic acids and the soil, as they have the greatest effects on the reproductive and vegetative systems of the most important fruits. The presence of phenolic components, which have strong antioxidant properties, strengthens the humic acid to improve the physicochemical traits of the fruits, like the number of fruits, the number of shoots, and the total soluble solids, vitamin C, and phenolic compounds. Due to their antibacterial, antiviral, anti-inflammatory, antifungal, and anticancer characteristics, they are used for preventing decay, animal husbandry, as well as being environmentally friendly. For this case, the current review focuses on the impact of humic acid foliar application on the progression of physical and chemical parameters. The objectives of this review are to explore the methods by which humic acid supports improving the vegetative and chemical traits of various fruits. In addition, it encompasses the application techniques and various concentrations to specific characteristics of the fruits. This review synthesizes existing knowledge on the impact of humic acid on fruit quality, highlighting areas where research is lacking or findings are inconsistent. By providing a foundation for future studies, it explores unmapped aspects of humic acid application in fruit production and offers insights and recommendations to farmers and agricultural scientists on the effective use of humic acid to enhance and improve fruit quality.

This article aims to explain the association between ethics and politics in the ethical-political school of Imam Muhammad Ghazali with revealing and interpretive approach. This investigation carried out using a descriptive-analytical method through the collection of data, historical information, and documents. Imam Ghazali's works have been considered as a text that is consistent with reality. Thus, the question arises: What is the relationship between ethics and politics in Imam Ghazali's ethical and political school? In Ghazali's moral and political system, morality leads to modification and politics leads to perfection. Therefore, these two elements have better and more systematic correlation and stability. To achieve the research objective, the discussions have been organized into three sections. In the first part, hermeneutics is presented as the theoretical framework of the research. The second section attempts to explain the moral and political school of Imam Muhammad Ghazali. Finally, in conclusion, inferential suggestions from the discussions offered are presented in order to compile and process the explanation of the relationships between ethics and politics in the ethical and political school of Imam Muhammad Ghazali. The result and outcome of the present study shows that, in accordance with Imam Ghazali's ethical and political school, ethics and politics have close relationships. These relationships are most evident in the definitions of the nominal explanation of the concept of ethics, politics, and the class of sciences. Considering his interpretations of ethics and politics, we are led to the conclusion that Imam Ghazali theorized the theory of moral politics and considers the theory of political ethics to be baseless.

We have proposed the design and synthesis of a compact, low-profile, flexible substrate integrated waveguide (SIW) wearable filtering antenna (filtenna) for 5 G communication, along with two parasitic resonator patches. We initially used a half-mode rectangular-shaped substrate-integrated (HMRSI) cavity as a resonating patch to minimize circuit size. The HMRSI cavity is located in close proximity to two parasitic truncated corner patches that serve as both the radiator and the final stage resonators, thereby optimizing filtering performance and expanding the operating bandwidth. The interaction of the parasitic patches with the HMRSI cavity produces one radiation null at the upper band-edges, while the corner truncation and notching on the parasitic patches with defected ground creates the other, enhancing the roll-off rate. Typical filter synthesis technology guides the design of the antenna. We have manufactured and measured an optimized prototype. The proposed flexible filtenna demonstrates excellent out-of-band selectivity, and its measurement aligns well with simulated ones, achieving an 8.2% fractional bandwidth (FBW), a maximum realized gain of 6.1 dBi, and a flat passband gain response. The proposed filtenna has also studied the human body and achieved a low specific absorption rate (SAR), which enables it to be an on-body wearable filtenna.
