THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

A fast-Fourier-transform method of topography and interferometry is proposed. By computer processing of a noncontour type of fringe pattern, automatic discrimination is achieved between elevation and depression of the object or wave-front form, which has not been possible by the fringe-contour-generation techniques. The method has advantages over moire topography and conventional fringe-contour interferometry in both accuracy and sensitivity. Unlike fringe-scanning techniques, the method is easy to apply because it uses no moving components.

TiO(2) is one of the most studied compounds in materials science. Owing to some outstanding properties it is used for instance in photocatalysis, dye-sensitized solar cells, and biomedical devices. In 1999, first reports showed the feasibility to grow highly ordered arrays of TiO(2) nanotubes by a simple but optimized electrochemical anodization of a titanium metal sheet. This finding stimulated intense research activities that focused on growth, modification, properties, and applications of these one-dimensional nanostructures. This review attempts to cover all these aspects, including underlying principles and key functional features of TiO(2), in a comprehensive way and also indicates potential future directions of the field.

For past many eternities human being is indulged in a process, the process of reaching towards perfection and of being perfect. Many researchers and technocrats are still inventing things and many had already changed our lifestyles and made this world a comfort place to live in. This mad run invited many unwanted guests, pollution of air/land/water, pollution of society/body/mind, which further leads to many sufferings and stressful life. Developing the ability to lax your body and calm your mind is significant because it helps you to control your activation level and channel your focus, both needed for stability. Yoga, a system of mental and physical training, concerns with postures, breathing exercises, meditations, which claim to give knowledge of reality. In the area of mental relaxation and meditation, shavasana and the sitting postures maintain the balance by their equal input of physical stimuli. Yoga Nidra is a systematic method of inducing complete mental, emotional and physical relaxation. It means psychic sleep, where conscious intellectual mind disappears, subconscious mind becomes active and unconscious mind merges with the subconscious, and there we have no concept of time and space. Yoga Nidra is an effective way to release stress and induce deep physiological rest and relaxation. Rotating the awareness around the different parts of the body in turn, as we do in Yoga Nidra, stimulates the chakras in a fully balanced way. During scientific experiments it has been seen that when you practice Yoga Nidra, α waves change immediately.

Yoga Nidra: a deep mental relaxation approach

Ulcerative colitis (UC) is an inflammatory chronic disease primarily affecting the colonic mucosa; the extent and severity of colon involvement are variable. In its most limited form, it may be restricted to the distal rectum, while in its most extended form the entire colon is involved. Ulcerative colitis is identified by mucus diarrhea, tenesmus, bowel distension, and anemia. 5-aminosalicylic acid drugs, steroids, and immunosuppressant are used for therapy of ulcerative colitis. The annual occurrence of disease in Asia, America, and Europe was estimated to be 6.3, 19.2 and 24.3 per 100,000 people-years. The main challenges in the management of the diseaseare drug-related side-effects and local targeting. To overcome these challenges probiotics and micro and Nano particulate system auspicious approaches to overcome drug-related adverse side effect and local targeting. Upon ingestion, the probiotics can result in health beneficial effects. Probiotics are mainly used as gut modulators but are also now days explored for their use in ulcerative colitis. Micro and Nano particulate drug delivery system have been achieving huge importance for targeting of the drug to colon locally at a controlled and sustained rate. The main objective of this article is to explore probiotics and micro and nano particulate approaches for the suitable targeting and overcome the drug-associated side effect.

We report the studies on photoluminescence (PL) of organic phosphor coated on a diffusing surface using a blue inorganic light-emitting diode (LED) array as an excitation source. The organic phosphor composite coated diffuser was used to scatter the directional blue light from the LED array. Some of the blue light is absorbed by the organic phosphor composite and the phosphor molecules are excited and re-emit light at longer wavelengths due to the PL process. The output light consists of scattered blue light plus phosphor generated broadband yellow light, thus making white light. The diffuser was made up of a plastic substrate coated with an organic composite of small molecule fluorescent material zinc(II)bis(8-hydroxyquinoline) (Znq2) doped with different percentages of electro-phosphorescent metal complex iridium(III)bis(2-methyldibenzo-[f, h] quinoxaline) (acetylacetonate) ([Ir(MDQ)2(acac)]). By means of changing the concentration and the thickness of the phosphor composite material the colour coordinates of white light were achieved. The CIE coordinates and correlated colour temperature were calculated for various thicknesses and phosphor composite concentrations and the results are reported.

The bioefficacy of biocontrol agents, Trichoderma harzianum isolates (Th-M & Th-P) and Trichoderma viride isolate (Tv) was studied against Fusarium head blight pathogen of wheat ( Fusarium graminearum ) in vitro and under green house conditions (pot trial). Dual culture technique was used for testing the potential of Trichoderma isolates against seven isolates of F. graminearum in vitro. Trichoderma harzianum (Th-M) was found most effective in significantly reducing the radial growth of all F. graminearum isolates followed by T. viride . Foliar application of T. harzianum (M) and T. viride alone and in combination significantly reduced the disease severity as compared to control. Maximum reduction in disease severity was achieved with combined application of T. harzianum and T. viride .
