Although existing books on Geometrical Drawing are numerous, and some of them excellent, yet in a wide experience I have found no book quite adapted to the requirement of students in schools of art, still less suitable as a class-book for use in school for general education.
Guaiacol, hydrogen peroxide (H2O2, 30%), Sodium acetate (NaCH3COO), potassium dihydrogen phosphate (KH2PO4) and Tris-HCl were all obtained from Sigma-Aldrich Chemie GmbH Steinheim, Germany. The present study used zeferan, a local peach variety occurring in Iğdır central Melekli neighbourhood was used as the source of peroxidase enzyme. The Zeferan peach was collected in september and preserved at -20 °C.
chapter, we present a review on the normal contact pair manifolds under certain conditions on curvature tensors. Firstly, we give some fundamental facts on the contact pair manifolds and curvature tensors. Later, we present many results on NMCP manifolds under some flatness conditions of these curvature tensors. Finally, we examine some symmetry properties of normal contact metric pair manifolds with curvature tensors.

The decidedly great advantage of the Modern Mathematicians over the Ancients, has almost entirely a risen from the introduction and refinement of the Algebraic Analysis, united with the Differential and Integral Calculus; and particularly from the truly elegant and systematic mode which has been adopted in their application to problems connected with Geometry.

Professor Caldwell is a ready and copious writer. His prolific pen, in the course of a long and industrious life, has been employed in the discussion of most of the leading topics belonging to physiology. It has fallen in our way to have to speak of many of these productions, and generally we have been as forcibly impelled by a sense of justice, as predisposed by our feelings of personal regard for their author, to speak of them in terms of decided approbation. But in the present instance our language must be different, and on that account the task of reviewing the “Critique” is one which we assume with no pleasure. If we could have pronounced it an able paper, though coming short of its aim; if, among its numerous arguments-against animal chemistry, one solid objection had been adduced; if the adthor had even succeeded in pointing out the defects which, undeniably, attach to the doctrines of Liebig, we should have felt.
Application of The Principle of Hard and Soft Acids and Bases to Mechanisms of Bioinorganic Reactions -Monograph-
Tanja V. Soldatović
In this monograph, the influence of HSAB principle on preference of central metal ions to biologically relevant molecule has been discussed. Taking into account the author’s scientific work on investigations the kinetics and mechanism of interaction between transition metal-based compounds with potential antitumor activity, such as Pt(II), Pd(II) (soft acids) and Zn(II) and Cu(II) (intermediate acids) and biomolecules, a review of the scientific results in this field has been made. Author for more than two decades, investigate substitution processes of monofunctional, bifunctional and dinuclear complexes of platinum(II), palladium(II), lately, zinc(II) and copper(II) with biologically relevant nucleophiles. In this monograph selected results from this field have been reported, considering the high velocity of developments. I hope this monograph will help the researchers and will be catalytic for the students to join research groups which are motivated and engaged in discovery of new knowledges which contribute to expansion of bioinorganic chemistry fields.
