By using an extensive three-dimensional discrete element method, we numerically investigate the effects of lightweight particle content on the mechanical strength of the cylindrical aggregates, randomly composed of two different groups of primary particles: light (low stiffness) and heavy (high stiffness), and the stress contribution of the heavy-heavy, light-heavy, and light-light interactions on the mechanical behavior of such aggregates, subjected to the compression test by using a constant downward velocity.

In this study, we systematically screened and assessed the antibacterial efficacy of five chitosan preparations of different viscosities and components. Additionally, we explored the synergistic antimicrobial potential of the most potent chitosan sample in combination with commonly employed antibiotics, including ampicillin, amoxicillin, oxacillin, and levofloxacin against four prevalent BM-causing pathogens: Staphylococcus epidermidis, Streptococcus agalactiae, Streptococcus uberis and Pseudomonas sp.

This research investigates the interactive effects of usability, the designer perspective and user expectations on the user experience (UX) of e-commerce websites. It incorporates the theoretical underpinnings of Norman’s (1988) seminal research specifically, Mental Models and Nielsen’s User Categories (1993) to explore the different mental models, domain and technology expertise of two distinct groups – users and designers – in the interaction with a selected system image, that of the e-commerce website.

This is an empirical investigation into the development of the accounting profession in Sri Lanka in the post-independence era. Taking the Institute of Chartered Accountants of Sri Lanka (ICASL) as a case, the study researches the accounting professionalization process during the past five decades (1959-2010). Thus, the study focuses on the struggles and interactions between competing groups and organisations within the accounting profession.

This study was conducted at some universities in Ho Chi Minh city in Vietnam. The objectives aimed at finding out the similarities and differences in teachers’ and students’ beliefs about classroom interactions in large non-English majored classes and how teachers’ and students’ beliefs about classroom interactions corresponded to their actual practice. Data were collected from questionnaires for 100 teachers teaching English to non-English majors and 100 students. Besides, semi-structured interviews were conducted with representative teachers and students from both groups.

An interactive survey was conducted during 2016-17 to document insecticide usage pattern adopted by the farmers of Karnataka state to manage polyphagous pest Helicoverpa armigera in different host crops growing areas. Among the different group of insecticides the most popular amongst the farmers were emamectin benzoate 5 SG (39.44 %), rynaxypyr 18.5 SC (27.22 %) and profenophos 50 EC (23.89 %). The dominant host crops for H. armigera different in the state were cotton, pigeonpea in Raichur and Kalaburgi, chickpea (Gadag), chilli (Haveri) and tomato (Kolar).

. In this paper, we present an approach to lighting design in applications where the expected result of the lighting design process for a 2D image. In this approach, the lighting-by-example method using wavelet-based objective function is used in combination with an interactive interface in order to optimize lighting parameters for an object or a group of objects individually, and then the visual results of these separate processes are combined (utilizing 3D depth information) in the seamless generation of a final 2D image.

Chapter 11 - general transcription factors in eukaryotes. Eukaryotic RNA polymerases, unlike their bacterial counterparts, are incapable of binding by themselves to their respective promoters. Instead, they rely on proteins called transcription factors to show them the way. Such factors are grouped into two classes: general transcription factors and gene-specifi c transcription factors (activators). In this chapter we will survey the general transcription factors that interact with all three RNA polymerases and their promoters.

Trichloroisocyanuric acid synthesis process was studied by using DFT method. The obtained results demonstrate that the keto-enol isomerization of the cyanuric acid is a base-catalyzed reaction. It is possible that in the presence of NaOH the process of moving hydrogen in the cyanuric acid molecule and the reaction of neutralizing cyanuric acid can execute consecutively. And in this case NaOH plays the role as a donor of hydroxyl group catalyzing the movement of hydrogen and as neutralizing agent in an exothermal process.

In this communication, we report the synthesis of chitosan (CS, a biodegradable and biocom- patible natural polymer) [1] nanoparticles as drug carriers by ionic gelation. The method is based on ionic interactions between positively charged groups NH3 + of CS (in dilute CH3COOH solution) and negatively charged of sodium tripolyphos- phate, TPP).

The synthesis and characterization of chitosan (CS) nanoparticles used as drug carrier was reported. The formation of nanoparticles, taking place in an aqueous phase without using auxiliary toxic substances via the ionic interaction between NH3 + protonated group of CS and phosphate group of sodium tripolyphosphate (TPP) was monitored in situ by combined UV-vis and pH measurements. The synthesized nanoparticles were characterized by TGA/DTA, XRD and TEM. The particle size, estimated by TEM, was found around 50 - 70 nm, with a quite uniform size distribution.
