Bologan's black weapons in the open games : how to play for a win If white avoids the Ruy Lopez
\"If you are ready to play the Ruy Lopez with Black, you also need to be prepared if white avoids the Ruy. In this book Victor Bologan covers all relevant lines with a well laid-out, clearly explained and eminently playable set of responses. But this is not just another chess opening repertoire book. Bologan presents TWO different options against every main line: a common sense approach and an aggressive weapon. It's actually two books in one!\"--Back cover.

Numerical Analysis for Shear Strength of Composite Box Steel-Concrete Beam Transverse Intermediate to Large Openings
This research paper presents a numerical analysis of composite box steel-concrete beams with transverse intermediate to large openings, conducted using the ABAQUS program. The study focused on various parameters, including opening size, shape, location, shear span to effective depth ratio, compressive strength, and diameter of rebars, to understand their effects on the shear load capacity of the beams. The results demonstrated a strong agreement with experimental data, with a correlation ranging from 0.927 to 1.023. Key findings include Increasing the opening size from 90x90 mm to 110x110 mm and from 110x110 to 136x136 led to a 12.7% and 42.4% respectively decrease in shear load, Changing the shape of openings from square to circular decreased the shear load by 14.7% for 90 mm openings and 14.2% for 110 mm openings, while increased the shear load by 15.25% for 136 mm. Moving transverse openings closer to the loads by 126 mm reduced the shear load by 7.5% for 90x90 mm openings, 9.8% for 110x110 mm openings and 17.2% for 136×136 mm openings. The difference in shear load between the highest and lowest (a/d) ratios is 12.5% for 90×90 mm openings, 7.2% for 110×110 mm openings, and 0.8% for 136×136 mm openings. Beams with a compressive strength of 37.5 MPa showed higher shear loads compared to those with 30 MPa, with increases of slight change, and the shear load increased of slight change for beams with reinforcement (2ø25-2ø16) compared to those with (3ø16) for 90x90 mm openings, 110x110 mm and 136x136 mm openings.

'Switch' catalysis: from monomer mixtures to sequence-controlled block copolymers
A 'Switch' catalysis method is reviewed whereby a single catalyst is switched between ring-opening polymerization and ring-opening copolymerization cycles. It allows the efficient synthesis of block copolymers from mixtures of lactones, epoxides, anhydrides and carbon dioxide. In order to use and further develop such 'Switch' catalysis, it is important to understand how to monitor the catalysis and characterize the product block copolymers. Here, a step-by-step guide to both the catalysis and the identification of block copolymers is presented.
This article is part of a discussion meeting issue ‘Providing sustainable catalytic solutions for a rapidly changing world’.

Review of Core/Shell Quantum Dots Technology Integrated into Building’s Glazing
Skylights and windows are building openings that enhance human comfort and well-being in various ways. Recently, a massive drive is witnessed to replace traditional openings with building integrated photovoltaic (BIPV) systems to generate power in a bid to reduce buildings’ energy. The problem with most of the BIPV glazing lies in the obstruction of occupants’ vision of the outdoor view. In order to resolve this problem, new technology has emerged that utilizes quantum dots semiconductors (QDs) in glazing systems. QDs can absorb and re-emit the incoming radiation in the desired direction with the tunable spectrum, which renders them favorable for building integration. By redirecting the radiation towards edges of the glazing, they can be categorized as luminescent solar concentrators (QD-LSCs) that can help to generate electricity while maintaining transparency in the glazing. The aim of this paper is to review the different properties of core/shell quantum dots and their potential applications in buildings. Literature from various disciplines was reviewed to establish correlations between the optical and electrical properties of different types, sizes, thicknesses, and concentration ratios of QDs when used in transparent glazing. The current article will help building designers and system integrators assess the merits of integrating QDs on windows/skylights with regards to energy production and potential impact on admitted daylighting and visual comfort.
