This study investigates the properties of a binary binder system consisting of calcined dolomite powder (CDP) and rice husk ash (RHA). To conduct the study, a reference mixture containing 100% ordinary Portland cement (OPC) and six other concrete mixtures containing a binary binder system with different proportions of CDP and RHA were prepared and tested. Testing was conducted for workability, setting time, dry shrinkage, and mechanical strength at different curing times. The results indicate that the binary system CDP-RHA have mechanical properties better than that of OPC. In addition, the results indicate that the mixture containing 50% CDP and 50% RHA is optimal in terms of mechanical strength.

Current Strategies and Future Dimensions in the Development of KRAS Inhibitors for Targeted Anticancer Therapy.

KRAS is a proto-oncogene that is found to be mutated in 15% of all metastatic cancers with high prevalence in pancreatic, lung, and colorectal cancers. Additionally, patients harboring KRAS mutations respond poorly to standard cancer therapy. As a result, KRAS is seen as an attractive target for targeted anticancer therapy.

(1) Background: Medical graduates who have undertaken longitudinal rural training have consistently been found to be more likely to become rural doctors and work in primary care settings. A limitation of such findings is the heterogeneous nature of rural medical education and contested views of what constitutes 'rurality', especially as it is often reported as a binary concept (rural compared to metropolitan). To address the identified gaps in workforce outcomes for rural medical training and to demonstrate accountability to the communities we serve, we investigated whether Longitudinal Integrated Clerkship (LIC) graduates are practicing in communities with similar rural classification to those where they trained.

Purpose: There are no standardized chest binding guidelines available to health care providers serving transgender and nonbinary individuals, exacerbating the significant health disparities affecting this community. Our study aimed to demonstrate the need for further evidence-based investigations into the association between chest binder type and health outcomes.
Methods: For this cross-sectional observational study, a community-engaged online survey evaluating individuals' experiences with their current or most recent chest binder was distributed to LGBTQ+ community centers, online forums, and clinics from July to November 2021.

An alternative approach to reducing the clinker factor, i.e., worldwide CO emissions resulting from the production of composite cement, is to replace these materials with supplementary aluminosilicate-based materials that promote the formation of alkali-activated cements, whose elevated temperature resistance, limited permeability, strong binding properties, excellent durability, high chemical corrosion resistance, confinement of toxic waste, and environmentally low impact have attracted a lot of attention in the cement industry.

This study examines the impact of sodium citrate and a plasticizing additive, along with their sequential introduction into a cement slurry or concrete mix, on the heat evolution of the cement slurry, the microstructure, phase composition of the cement paste, and the compressive strength of fine-grained concrete. The binder used in this research was a blended binder consisting of 90% Portland cement and 10% calcium aluminate cement. This type of binder is characterized by an increased heat evolution and accelerated setting time.
