Experiments in Plant Hybridisation by Gregor Mendel Pdf
Experiments which in previous years were made with ornamental plants have already afforded evidence that the hybrids, as a rule, are not exactly intermediate between the parental species. With some of the more striking characters, those, for instance, which relate to the form and size of the leaves, the pubescence of the several parts, etc., the intermediate, indeed, is nearly always to be seen; in other cases, however, one of the two parental characters is so preponderant that it is difficult, or quite impossible, to detect the other in the hybrid. from 4. The Forms of the Hybrid One of the most influential and important scientific works ever written, the 1865 paper Experiments in Plant Hybridisation was all but ignored in its day, and its author, Austrian priest and scientist GREGOR JOHANN MENDEL (18221884), died before seeing the dramatic long-term impact of his work, which was rediscovered at the turn of the 20th century and is now considered foundational to modern genetics. A simple, eloquent description of his 18561863 study of the inheritance of traits in pea plantsMendel analyzed 29,000 of themthis is essential reading for biology students and readers of science history. Cosimo presents this compact edition from the 1909 translation by British geneticist WILLIAM BATESON (18611926).
Transport in Plants II by U. Lüttge,M.G. Pitman Pdf
As plant physiology increased steadily in the latter half of the 19th century, problems of absorption and transport of water and of mineral nutrients and problems of the passage of metabolites from one cell to another were investigated, especially in Germany. JUSTUS VON LIEBIG, who was born in Darmstadt in 1803, founded agricultural chemistry and developed the techniques of mineral nutrition in agricul ture during the 70 years of his life. The discovery of plasmolysis by NAGEL! (1851), the investigation of permeability problems of artificial membranes by TRAUBE (1867) and the classical work on osmosis by PFEFFER (1877) laid the foundations for our understanding of soluble substances and osmosis in cell growth and cell mechanisms. Since living membranes were responsible for controlling both water movement and the substances in solution, "permeability" became a major topic for investigation and speculation. The problems then discussed under that heading included passive permeation by diffusion, Donnan equilibrium adjustments, active transport processes and antagonism between ions. In that era, when organelle isolation by differential centrifugation was unknown and the electron microscope had not been invented, the number of cell membranes, their thickness and their composition, were matters for conjecture. The nature of cell surface membranes was deduced with remarkable accuracy from the reactions of cells to substances in solution. In 1895, OVERTON, in U. S. A. , published the hypothesis that membranes were probably lipid in nature because of the greater penetration by substances with higher fat solubility.
On the Origin of Species Illustrated by Charles Darwin Pdf
On the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life), [3] published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology.[4] Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation
Macrophages and Natural Killer Cells by Sigurd J. Normann Pdf
This book is the outcome of a meeting held in Davos, Switzerland, February 7-12, 1982 focused primarily on mononuclear phagocytes and on natural killer (NK) cells. This IX International RES Congress was attended by 489 scientists from 31 countries and there were 340 scientific presentations in oral or poster session. The essential purpose of the Congress was to bring together scientists representing various aspects of mononuclear phagocyte biology to review and examine cri~ically the effects and mechanisms of macrophage growth control as well as the participatio~ of these cells in the afferent and efferent limbs of the immune response. Additional topics included the production and distribution of mono nuclear phagocytes; the intrinsic and extrinsic regulation of these cells; and the origin, nature, function and regulation of NK cells. The ultimate goal of the Congress was to enhance communication between scientists in various countries and disciplines so that new research directives could be defined with which to explore basic aspects of macrophage and NK cell participation in the control of cancer and infection.

Stopping By Woods on a Snowy Evening by Robert Frost Pdf
The woods are lovely, dark and deep, But I have promises to keep, And miles to go before I sleep, And miles to go before I sleep. From the illustrator of the world’s first picture book adaptation of Robert Frost’s “The Road Not Taken” comes a new interpretation of another classic Frost poem: “Stopping By Woods on a Snowy Evening.” Weaving a simple story of love, loss, and memories with only illustrations and Frost’s iconic lines, this stirring picture book introduces young readers to timeless poetry in an unprecedented way.
Applications of Plant Cell and Tissue Culture by Gregory R. Bock,Joan Marsh Pdf
This work deals with basic plant physiology and cytology, and addresses the practical exploitation of plants, both as crops and as sources of useful compounds produced as secondary metabolites. Covers problems of commercial exploitation, socio-legal aspects of genetic engineering of crop plants, and of the difficulties of marketing natural compunds produced by cells under artificial conditions.
