The 600 words in each book of this series along with the additional target words presented in the appendices included in the first three books of the series are the most useful words in English. They were found by analysis of a collection of English course books from various levels in the primary, secondary and tertiary school systems. The words included in this series were chosen because they occurred many times in different levels of these materials. Book 3 includes 30 units, please refer to the documentation for more details.

This resource book is designed to be used alongside the natural English upper-intermediate student's book to give students at this level extra reading and writing practice. However, the materials are freestanding and can be used in any order as a dip-in resource for the teacher. The materials and tasks have been chosen for the general English user who wants to improve their reading and writing skills and also for students using English for their studies or for work purposes. It also covers skills useful for public exams such as IELTS, BEC or FCE.

Ebook "Graph theory with applications" is intended as an introduction to graph theory. Our aim has been to present what we consider to be the basic material, together with a wide variety of applications, both to other branches of mathematics and to real-world problems. Included are simple new proofs of theorems of Brooks, Chvátal, Tutte and Vizing. The applications have been carefully selected, and are treated in some depth. We have chosen to omit all so-called 'applications' that employ just the language of graphs and no theory.

In this paper, we present the results of computation for design of a new neutron imaging facility located at channel No. 3 of the Dalat Reactor. The design has two main parts: The neutron beam collimator and the radiation safety system. For the neutron beam collimator, the computational parameters such as neutron flux, cadmium ratio as well as ratio of neutron dose/gamma dose are reported.

The recent advances in the study of the unique capabilities of monolayer crystals had predicted piezoelectricity in two-dimensional (2D) group IV chalcogenides which are not present in their bulk forms. In this study, the predicted piezoelectric properties of was experimentally explored through Piezoelectric Force Microscopy (PFM). Tin Sulfide (SnS), Tin Selenide (SnSe), Germanium Sulfide (GeS), were exfoliated from their bulk forms by the top down methods of liquid sonication, while and Tin Disulfide (SnS2) mechanically exfoliated by tape.

This study, however, focuses more on generally well-received blogs generated by widely accepted beauty writers aged 25-35 (the quality of well-received is defined by the number of followers in each page – averagely 10,000 and above). Additionally, for the collecting data of the study to be conducted thoroughly, entries with the occurrence of code-switch rather than randomly chronological posts are chosen as the primary material for valid and reliable linguistic analysis.

Porous biphasic calcium phosphate (BCP) ceramics exhibit good biocompatibility and bone conduction but are not inherently osteoinductive. To overcome this disadvantage, we coated conventional porous BCP ceramics with nano-hydroxyapatite (nHA). nHA was chosen as a coating material due to its high osteoinductive potential.

This study aims to investigate the adsorption capacity of ammonium NH4 + , nitrite NO2 - and nitrate NO3 - onto rice husk biochar (RHB) obtained from 550 °C pyrolysis temperature in the context of using low-cost absorbent for recirculating aquaculture system (RAS). Raw RHB at its original size 5–8 mm has been chosen for testing its adsorption capacity as well as several key material properties (pHPZC, surface area, and elemental analysis).

In this paper, one-dimensional photonic crystal distributed feedback structures were chosen for simulating the photonic modes. The corresponding photonic bands were calculated by using a numerical method for solving the master equation, while the reflectivity spectra of the structures were simulated by using a rigorous coupled wave analysis method.

Cellulose constitutes bulk of the plant cell wall materials and the most abundant and renewable non-fossil carbon source on earth. Cellulose degrading fungi play an important role in recycling of cellulosic materials. Thus, this study was designed to screen endophytic fungi isolated from Cameroonian medicinal plants for their cellulase activity. The plate-clearing assay and enzyme assay methods were used for screening of potent cellulolytic endophytic fungi. The promising was chosen for filter paper cellulase (FPCase) and carboxymethyl cellulase (CMCase) assay.
