It has been the goal of the Philippine education system to innovate the curriculum into globally competitive structure. Following the implementation of the K to 12 curriculum in , the Department of Education facilitated various of trainings to the teachers.
The application of superabsorbent polymer hydrogels in the oil and gas industry for reservoir and well management is gaining more traction. In this study, the swelling performance and adsorption kinetics of two commercial superabsorbent polymer hydrogels—poly acrylamide-co-acrylic acid potassium salt and sodium polyacrylate—were evaluated based upon their stimuli response to pH and salinity at varying temperature and reaction time periods. Characterisation and evaluation of the materials were performed using analytical techniques—optical microscopy, scanning electron microscopy, thermal gravimetric analysis and the gravimetric method. Experimental results show that reaction conditions strongly influence the swelling performance of the superabsorbent polymer hydrogels considered in this study. Generally, increasing pH and salinity concentration led to a significant decline in the swelling performance of both superabsorbent polymer hydrogels. These findings serve as a guideline for field engineers in the use of superabsorbent polymer hydrogels for a wide range of oilfield applications.
RNA is becoming more important as an increasing number of functions, both regulatory and enzymatic, are being discovered on a daily basis. As the RNA boom has just begun, most techniques are still in development and changes occur frequently. To understand RNA functions, revealing the structure of RNA is of utmost importance, which requires sample preparation. We review the latest methods to produce and purify a variation of RNA molecules for different purposes with the main focus on structural biology and biophysics. We present a guide aimed at identifying the most suitable method for your RNA and your biological question and highlighting the advantages of different methods. In this review we present different methods for large-scale production and purification of RNAs for structural and biophysical studies.

Abstract The graphic design discipline has witnessed rapid technological developments and evolving contexts in the past two decades. In order to address the challenges presented by an increasingly knowledge-based society, the School of Design at the Hong Kong Polytechnic University has developed a new four-year BA Hons in Communication Design degree programme.
Berberine analogs bind to the RNA triplex non-cooperatively. The affinity of binding was remarkably high by about 5 and 15 times, respectively, for BC1 and BC2 compared to berberine. The site size for the binding was around 4. Based on ferrocyanide quenching, fluorescence polarization, quantum yield values and viscosity results a strong intercalative binding of BC1 and BC2 to the RNA triplex has been demonstrated. BC1 and BC2 stabilized the Hoogsteen base paired third strand by about
