Flavonoids are considered as a significant class of compounds among the natural products, exhibiting a variety of structural skeletons as well as multidirectional biological potentials. In structural elucidations of natural products, Nuclear Magnetic Resonance (NMR) spectroscopy has been playing a vital role; the technique is one of the sharpest tools in the hands of natural products chemists. The present resume deals with hard-core applications of such spectral technique, particularly in structural elucidation of flavonoids; different NMR techniques including 1H-NMR, 13C-NMR, and 2D-NMR [viz. 1H-1H COSY, COLOC, HMBC, HMQC] are described in detail.

AbstractIntroductionHard-core smokers have been identified as a potential public health challenge. The trans-theoretical model lacks the specificity to identify hard-core smokers. The precaution adoption process model (PAPM) is a stage-based behaviour change model which includes ‘no intent to quit’ as a distinct stage and so may be useful in identifying hard-core smokers.AimsThe aim of this study was to apply the PAPM to a community based sample of smokers to determine whether it provides a useful approach to identifying hard-core smokers.MethodsWe surveyed smokers in Australia who were recruited through social media and an online data collection agency.ResultsThe sample included 336 current smokers, 11.9% were in Stage 4 of the PAPM – i.e. had decided not to quit. Stage 4 smokers are more resistant to quitting and marked by their similarities to hard-core smokers. This is further amplified when addressing Stage 4 smokers with no previous quit attempt.ConclusionsStage 4 smokers with no previous quit attempts are aligned with a hard-core smoker profile with higher levels of nicotine dependence, greater cigarette consumption and low socio-economic status. Further research is required to determine if PAPM is a valid predictive model for identifying hard-core smokers in clinical practice.

Collision between rigid three-dimensional objects is a very common modelling problem in a wide spectrum of scientific disciplines, including Computer Science and Physics. It spans from realistic animation of polyhedral shapes for computer vision to the description of thermodynamic and dynamic properties in simple and complex fluids. For instance, colloidal particles of especially exotic shapes are commonly modelled as hard-core objects, whose collision test is key to correctly determine their phase and aggregation behaviour. In this work, we propose the Oriented Cuboid Sphere Intersection (OCSI) algorithm to detect collisions between prolate or oblate cuboids and spheres. We investigate OCSI’s performance by bench-marking it against a number of algorithms commonly employed in computer graphics and colloidal science: Quick Rejection First (QRI), Quick Rejection Intertwined (QRF) and a vectorized version of the OBB-sphere collision detection algorithm that explicitly uses SIMD Streaming Extension (SSE) intrinsics, here referred to as SSE-intr. We observed that QRI and QRF significantly depend on the specific cuboid anisotropy and sphere radius, while SSE-intr and OCSI maintain their speed independently of the objects’ geometry. While OCSI and SSE-intr, both based on SIMD parallelization, show excellent and very similar performance, the former provides a more accessible coding and user-friendly implementation as it exploits OpenMP directives for automatic vectorization.

Constructive Engagement

Modern complex contracts require cooperation, solid effective governance and a hard core of clear and workable terms and conditions to make them work. In this essay I explore exactly what cooperation and governance mean through the lens of a major global survey of contract practitioners. I discuss formal and informal elements of contract management because both matter. I find that contract managers show a marked reluctance to use punitive measures, but that value is seen in escalation, negotiation, communication, and professional governance. These require constructive engagement, that the parties talk, communicate, and work together to find the cause of the problem and agree solutions. I conclude that respondents are more interested in performance than in revenge, and that the key task is about making the contract work.
