Comparative Analysis of FIR Digital Filters for Noise Reduction in EMG Signal
Abstract: In the performance of electromyogram (EMG) signal, signal acquisition must be noise free. This paper deals with the application of digital finite impulse response (FIR) filter on the raw EMG signal. In this paper different window techniques are used to design FIR filter and after designing the filters their values are used to calculate signal-to-noise ratio (SNR), power spectral density (PSD), and standard deviation. The results of SNR, PSD and …

Effect of Diarrhea at Admission on Time to Recovery in Treatment of Severe Acute Malnourished Children in Inpatient Therapeutic Feeding Program in Tigray Region, Ethiopia
Abstract: The mortality rate in inpatient settings remained unacceptably higher, 20–30% for marasmus and 50–60% for Kwashiorkor. This is due to inappropriate case management and co-morbidities mainly diarrhea. Despite, there was no study conducted to show the effect of diarrhea at admission on the length of time to recovery in the treatment of severe acute malnutrition among children aged 6–59 months and then there is little understanding about this issue. The …

Polymeric Hybrid Systems Engineered with Multiple-Stage Energy Absorption for Temperature Control
Abstract: Polymer–composite based phase change systems offer an effective strategy for adaptive thermal management; however, most existing systems exhibit single-stage latent heat transitions, limiting their applicability in environments with fluctuating thermal loads. In this study, a thermoplastic polyurethane (TPU) polymer matrix was reinforced with two microencapsulated paraffin-based phase change materials (PCM-A and PCM-B) to achieve multi-level latent heat storage behavior. The fabricated TPU/PCM-A10–B20 polymer–composite demonstrated two distinct endothermic transitions at approximately …

Floating In-Situ Gel for Gastric Retention Delivery
Abstract: When taken orally, medications with a limited window of absorption in the gastrointestinal tract (GIT) are typically accessible to the extremities due to the partial release of the active component and the brief residence period at the absorption site. Because they prolong the duration of the drug's presence in the stomach, they are made with high density and have the capacity to swell. Because oral fluids go more quickly through …
