Synthesis of Geopolymer from a Novel Aluminosilicate-Based Natural Soil Precursor Using Electric Oven Curing for Improved Mechanical Strength.

Natural soil (NS)-based geopolymers (GPs) have shown promise as environmentally friendly construction materials. The production of ordinary Portland cement is known to release significant amounts of greenhouse gas (CO) into the atmosphere. The main objective of this work is to synthesize a geopolymer (GP) from an uncommon aluminosilicate-based NS and a sodium silicate (SS) activating solution that would not only minimize the emission of harmful gases, but also offer improved mechanical strength.

In current problem, the analytical simulations for performed for thermos-migration flow of nanofluid subject to the thermal radiation and porous media. The moving wedge endorsed the flow pattern.

Environmental-friendly extraction of Peepal (Ficus Religiosa) bark-based reddish brown tannin natural dye for silk coloration.

The present study aims to extract a natural reddish brown colorant from Peepal (Ficus religiosa) for silk dyeing using the microwave radiation process (MW). The colorant was isolated in aqueous and acidic media, and MW treatment for 1, 2, 3, 4, and 5 min has been given to both fabric and extract to observe changes in color intensity. The dye variables have been optimized, and for sustainable shade making process with good fastness, 1.

Healing of a large avulsed mandibular bony segment: report of a unique case.

This case report puts an emphasis on retaining and re-fixing any avulsed bony segments in the maxillofacial region and maintaining the periosteal layer whenever possible, especially in young patients. Adequate bony fixation and watertight soft tissue closure are vital components for bone healing. The healing potential of facial bones is much higher as compared to the long bones, due to the superior blood supply.

Devoid Knowledge and Low Adherence Precipitate Uncontrolled Blood Pressure: A Depiction From Cross-Sectional Study.

Objective: The present study was aimed to assess knowledge regarding disease, adherence to medication and blood pressure control among hypertensive patients.

Methods: A cross-sectional study involving 384 hypertensive patients attending a tertiary care, public sector hospital in Islamabad, Pakistan, was conducted. Data was collected by using Urdu versions of pre-validated hypertension knowledge questionnaire and Medication Adherence Scale by Morisky.

Person Re-Identification Using Deep Modeling of Temporally Correlated Inertial Motion Patterns.

Person re-identification (re-ID) is among the essential components that play an integral role in constituting an automated surveillance environment. Majorly, the problem is tackled using data acquired from vision sensors using appearance-based features, which are strongly dependent on visual cues such as color, texture, etc., consequently limiting the precise re-identification of an individual.

sessment Of Blood Pressure and Health-Related Quality of Life Among Hypertensive Patients: An Observational Study.

Objectives: Objective • Health-related quality of life (HRQoL) is an important tool in the assessment of treatment outcomes. Healthcare professionals use the concept of HRQoL to measure factors other than illness which affect human health and its status. Patient's everyday activities are adversely affected by hypertension (HTN) and results in decreased self-confidence.

Effect of leaching with 5-6 N H2SO4 on thermal kinetics of rice husk during pure silica recovery.

Rice husk is a potential source for renewable energy and silica. To extract the maximum amount of silica, usually the rice husk is treated with strong acids that burn the organic part leaving behind a black residue. In this research, sulfuric acid is used as an oxidizing agent.

MRSA colonisation in spinal cord injury: implications on patients rehabilitation.

MRSA has become a major cause of nosocomial and community acquired infections in the past few years. Our hypothesis is that MRSA colonisation affects the length of stay in hospital, thereby adding a strain on resources. Data from the last 20 patients admitted to the Spinal Injury Care Unit (SICU) who were MRSA positive (study group) have been analysed and then matched with data from 20 patients who were MRSA negative (control group) to compare their total hospital stay and the factors which affect the length of hospital stay.
