Optimized normal and distance matching for heterogeneous object modeling

This paper presents a new optimization methodology of material blending for heterogeneous object modeling by matching the material governing features for designing a heterogeneous object. The proposed method establishes point-to-point correspondence represented by a set of connecting lines between two material directrices. To blend the material features between the directrices, a heuristic optimization method developed with the objective is to maximize the sum of the inner products of the unit normals at the end points of the connecting lines and minimize the sum of the lengths of connecting lines. The geometric features with material information are matched to generate non-self-intersecting and non-twisted connecting surfaces. By subdividing the connecting lines into equal number of segments, a series of intermediate piecewise curves are generated to represent the material metamorphosis between the governing material features. Alternatively, a dynamic programming approach developed in our earlier work is presented for comparison purposes. Result and computational efficiency of the proposed heuristic method is also compared with earlier techniques in the literature. Computer interface implementation and illustrative examples are also presented in this paper

Dietotherapeutic potency of ornamental lentil dumpling, a traditional food preparation from South West Bengal, India

Gahana bori (in Bengali) or ornamental lentil dumpling is a state-of-art preparation designed in the form of paisleys, ornaments or flowers, used as a decorative adjunct with the main dish.. Here, we have made an attempt to evaluate the dirtotherapeutic potency of this traditional preparation. The principal ingredient is the Vigna mungo (blackgram/ urad bean). In its preparation, the soaked bean is pasted and placed on a cloth piece having a central small pore. The fermented paste is squeezed onto the poppy seeds containing plate in such a way that it looks like an ornament. The sundried preparation is generally fried in oil and served along with the meal. For the first time, we have scientifically explored Gahana bori. The number of total aerobes, total anaerobes, yeast, mould, and LAB were increased during soaking. The contents of free phenolics and flavonoids were increased in the fermented paste and that also reflected by the higher in vitro DPPH antioxidant activity. The levels of B-group of vitamins particularly the quantity of riboflavin, thiamin, folic acid, vitamin B12, and vitamin C were also enriched in the products. The water extract of this product exhibited a notable antibacterial activity against enteropathogens. Thus, the lentil-based Gahana bori is not only improved the appearance or presentation of food product but also the same have a good health beneficial potentiality

Tinkering at the edges or collaborative symbiosis? Ethnicity & rheumatology.

It is recognised that the epidemiology of disease as well as ill-health manifestations in minority populations may be at variance from orthodox formulations generated through traditional research and as described in the western medical literature. The relevance of this lies in the need to devise strategies for optimising healthcare in minority groups, which, in the UK, is a duty that has been imposed upon providers through the passage of legislation. This paper examines the effect of ethnicity on three common rheumatological conditions, namely rheumatoid arthritis, psoriatic arthropathy and osteoporosis, and concludes that a range of ethnicspecific issues have as yet failed to receive adequate attention in medical research, and, in addition, that there is a lacuna in comprehensive national strategies aimed at addressing health needs within this particular area. Approaches to remedying this deficiency are suggested based on information obtained through the lens of theme-specific workshops consisting of a mix of experienced healthcare professionals engaged in the care of individuals with rheumatological conditions. Multifaceted strategies need to be deployed to improve healthcare and to further the agenda of minority health issues in rheumatology
