Rasa Ratna Samucchaya being an important treatise of Rasashastra from 12th Century A.D consists of var-ious references regarding the usage of diverse animal resources. Resources like various products and body parts by different animals are derived and are used for various purposes in different context. They were used for the purpose of Shodhana (purification), Marana (incineration), Satwapatana (process of extrac-tion of chief constituent of any mineral), Druti nirmana (liquid form of any metal/mineral) and in prepara-tion of different Mushas (crucibles) like Vajra musha, Vajra dravanimusha, Garamusha etc., as well as in the preparation of Rasayogas (formulations). They are also used as Anupana/Sahapana (adjuvants), Pathya and Apathya (diet and regimens to be followed and avoided). Not only animal resources but utiliza-tion of resources of birds, insects, worm as well as aquatic resources like Pravala (coral), Mukta (pearl), Shankha (conch shell), Muktashukti (pearl oyster shell), Agnijara (ambergies) etc., were also explained. In addition, usage of Nara mutra (human urine), Narasthi (human bone) and Nari sthanya (breast milk) are also mentioned. This article is an effort to compile and enlist about the assorted animal resources that has been told in Ayurveda Rasashastric text Rasa ratna samucchaya written by Rasa Vagbhata.

AbstractAtomic force microscopy (AFM) and transmission electron microscopy (TEM) were used to investigate the fine structure of the calcite prisms from the pearl-oyster shell Pinctada margaritifera. The AFM analysis shows that the prisms are made of densely packed circular micro-domains (in the 0.1 μm range) surrounded by a dense cortex. The TEM images and diffraction patterns allow the internal structure of the micro-domains to be described. Each of them is enriched in Ca-carbonate. Hosted in distinct regions of each prism, some are fully amorphous, and some others fully crystallized as subunits of a large calcite single crystal. At the border separating the two regions, micro-domains display a crystallized core and an amorphous rim. Such a border probably marks out an arrested crystallization front having propagated through a previously bio-controlled architecture of the piling of amorphous micro-domains. Compared to recent data concerning the stepping mode of growth of the calcite prisms and the resulting layered organization at the μm-scale, these results give unexpected views regarding the modalities of biocrystallization.

Grating Structure

The structure giving rise to the colour of mother-of-pearl is investigated. The results generally are confirmatory of those given by Brewster and A. H. Pfund. Micro-photographs are reproduced showing the grating structure of a pearl-oyster shell, and the structure of parallel layers of an “ear” shell. The absorption spectrum of the latter is also reproduced. In agreement with the observed spacing of the layers under the microscope, it shows the reflexion to be of the second order.

Biodiesel is a renewable and environmentally friendly energy source. The process of using a homogeneous catalyst has several disadvantages, such as: removing a lot of waste water from washing the catalyst residue and cannot be reused. This catalyst is also low in corrosion and is more environmentally friendly. The purpose of this study was to study the preparation of heterogeneous catalysts from pearl shells applied to the cooking oil esterification reaction. The oil was then characterized by the XRD, XRF, SEM, and FTIR. The results of GCMS for reaction without catalysts yield only 27.07% by weight of alkyl ester, whereas using a catalyst is 93.4%. The influence of time, in the 60th minute, was the optimal time for the esterification reaction, and the effect of the weight of the catalyst which was 1% the optimal weight. This shows that pearl oyster shell catalyst can act as an esterification catalyst for used cooking oil and can be used as an alternative to a homogeneous catalyst substitute catalyst.

This essay explores two basic trajectories of the hydro-epistemology of sacred things in Indic cultures: things revealed by water—the visible gifts of water—and things hidden in water with which we can communicate only indirectly, by touching the water. Unlike Mircea Eliade’s concept of hierophany, this represents a mode of the sacred that cannot be auto-manifest and depends on water for radiating its sacrality. While the sacred things revealed by water—the conch shell, the bana linga, the svarnamukhi shila, the shaligrama shila—are water’s gifts to the Indic religions, there are things that are hidden by water; their hiddenness maintains their secrecy and sacrality. For instance, in certain Sati pithas, the petrified body parts of Goddess Sati are said to remain submerged in water. One can only touch them indirectly, by touching the water that is in touch with the Sati’s body. This article illustrates this two-pronged epistemology of the sacred that is propelled by water in Indic religious cultures.
