New Methods for Solution Systems of Linear Partial Differential Equation of the First Order

A new method for solving first-order systems of linear partial differential equations has been proposed. We use methods for reducing several matrices at the same time. This can often lead to an empirical solution or a major reduction in the complexity of the problem. Author (s) Details Dr. Yu. Bazylevych Prydniprovska State Academy of Civil…

Equilibrium Properties of Coulomb Glass

The equilibrium properties of Coulomb glass in two and three dimensions are discussed in this paper. To obtain various thermodynamic properties, we used Monte Carlo simulation. The device is annealed from a much higher temperature to very low temperatures below the transition temperature. Our findings vary from those of other simulations when it comes to…

Swelling Studies of PVA/Gelatin Hydrogels Synthesized Using Gamma Irradiation Technique

The aim of this study was to use the gamma irradiation technique to create various compositions of PVA/gelatin hydrogels. PVA and gelatin aqueous solutions with equal concentration were mixed in various weight ratios, namely 100/0, 75/25, 50/50, 25/75, and 0/100, and were subjected to a 25 kGy gamma irradiation dose. Powder XRD and FESEM analysis…

Emphasizing the Impact of Experiments in Physics Lessons – “Why, When, How Often?”

Science teaching and learning are incomplete without practical practises. The majority of school laboratories nowadays are well-equipped with experimental instruments and computer-based experimentation systems (Vernier, Pasco). Our main research question is whether using all of this equipment makes physics teaching more efficient. The aim of this paper is to explore the effectiveness of teacher-led laboratory…

Recent Study on Synthesis of Novel Pyrimido Oxazine and Their Derivatives

The present study used chalcone and urea as starting materials to make novel oxazine (1). The resulting compound 6-(4-chlorophenyl)-4-phenyl-6H-1,3-Oxazin-2-amine(2) was further reacted with ethyl 2-cyano-3,3-bis (methylthio) acrylate in DMF under reflux conditions, yielding novel 2-(4-chlorophenyl)-8-(methylthio)-6-oxo-4-phenyl-4,6,9,9 a-tetrahydro (3). Spectral methods were used to classify the synthesised compounds. At position 8, the compound (3) has a replaceable…

Copper Cold Gas-Dynamic Spray Processing for Highly Effective Antipathogenic Coatings: An Integrated Microstructural, Mechanics, and Materials Chemistry Perspective

The motivation for this endeavour is to gain a better understanding of microstructural characteristics, materials surface and bulk chemistry, as well as properties of cold sprayed traditional copper and nanostructured copper coatings in terms of antipathogenic contact killing and inactivation applications. During this work, the task of high strain rate induced severe plastic deformation states,…

Understanding the Basic Metallurgy of Duplex Stainless Steel

To understand the phase stability of ferrite at such elevated temperatures, duplex stainless steels with varying chromium content are taken and heat treated between the temperatures of 900 and 1000°C. Since the austenite grains remain unchanged after heat treatment, ferrite is the active step in duplex stainless steel. In addition, even though austenite is present…

Recent Advancement on Climate Resilient Millets for Food and Nutrition Security: Time to Promote for All Seasons

Millets are climate-resilient crops that can adapt to a wide range of environmental conditions, needing less irrigation and providing greater growth and productivity in low-nutrient input conditions with little reliance on artificial fertilisers and a reduced vulnerability to environmental stresses. Millets, which are nutritionally superior, are also limited to conventional customers and lower-income groups. To…
