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.

Global, regional, and national estimates of levels of preterm birth in 2014: a systematic review and modelling analysis.

Congenital prepubic sinus (CPS) is a very rare congenital anomaly. The baby generally present with discharge from an opening situated in midline below umbilicus to root of penis in male or clitoris in female child. The etiology of this congenital anomaly is not exactly known. There is debate in etiology as one theory support anomalous anterior abdominal wall closure and another support variant of dorsal urethral duplication. Here we are presenting the six cases of CPS with their management and brief discussion on theories that have been proposed for their etiology.

Congenital prepubic sinus: a series of six cases of extremely rare congenital anomaly

Chickpea (Cicer arietinum L.) is an important pulse crop in India and chief source of dietary protein in the vegetarian diet. The important Destructive disease in chickpea is dry root rot caused by necrotrophic fungus Rhizoctonia bataticola (Taub.) Butler emerging as a serious threat to the production worldwide. The screening of endophytes of leaf and stem isolates under dual culture used as two media PDA and TSA. The 12 isolates are significant on but three isolates are EBS-2, EBS-3, EBS-4 higher suppression towards on Rhizoctonia bataticola. These three isolates used as further methods that roll towel method (vitro) and net house (Pot Cultivation). The roll towel observations to be recorded as Germination percentage, Root, shoot lengths and vigour index. The EBL-3 and EBL-4 with highest germination percentage, Root length were EBL-2, 3 and shoot length, vigour index of EBL-3 highest percentage. The effect of EB on Rhizoctonia bataticola under pot culture observations were recorded that phenological parameters are Germination percentage, Pre-Post, Total mortality, Shoot, Root lengths and Fresh dry weights with different cohabitation on disease incidence. The cohabitation of T8EBL (2+3+4) T7EBL (4+2) are significant on four genotypes JG14, JG16, JG62 and JG315 with inoculation of pathogen. The EBL-3 isolate is that significant correlates in field and lab conditions.
