In five studies, we document the development and validation of the Non-verbal Communication Questionnaire (NVCQ). This eight-item measurement tool assesses how people perceive non-verbal cues across two dimensions of effective communication. These two dimensions, encouraging and discouraging non-verbal cues, are based on Khan and Zeb's (2021) version of the 10-part model of non-verbal communication.

Calcified chronic subdural hematoma (CCSDH) is a rare condition characterized by the accumulation of calcified blood between the dura mater and arachnoid membrane, typically following remote trauma. These lesions often present as space-occupying, extra-axial masses over the cerebral convexity and can mimic extra-axial tumors, such as calcified meningiomas. A 73-year-old male with a history of prostate cancer, hypertension, and hyperlipidemia presented with vision changes and mild papilledema.

Pre-sternal keloids are a distinct clinicopathological entity differing in many ways from keloids occurring elsewhere, as there are differences in pathogenesis, clinical presentation, and management. We have reviewed commonly used assessment scales like the Vancouver Scar Scale, the Patient and Observer Scar Assessment Scale, and the Detroit Keloid Scale and identified some shortcomings in applying them in assessing pre-sternal keloids. Therefore, we developed the AIIMS Bhopal pre-sternal keloid scale (ABPSKS), a pre-sternal keloid-specific tool to enable the assessment of the severity of the disease, the efficacy of treatment, and the comparison of outcomes of different treatment modalities.

In this study, a binary composite adsorbent based on activated carbon and phosphoric acid geopolymer foam (ACP) was prepared by combining phosphoric acid geopolymer (PAGP) with activated carbon (AC) and applied for the removal of methylene blue (MB). Activated carbon was thoroughly mixed with a mixture of fly ash and metakaolin in varying ratios, followed by phosphoric acid activation and thermal curing. The ACP adsorbent was characterized using scanning electron microscope (SEM), Fourier transform infrared (FTIR) spectrophotometer, X-ray diffractometer (XRD), surface area analyser (SAP), and thermogravimetric analyser (TGA).
