This work describes a microspore transformation method for the production of large number of homozygous doubled haploid transgenic wheat in one generation. PCR, DNA sequencing, Southern blot analyses and assay of the recombinant enzyme confirmed the presence of transgenes in T0 primary transformants and their stable inheritance in homozygous T1 DH progenies. Several factors for successful transformation were identified. In the first part of this work, optimal conditions for generating large numbers of DH wheat plants from microspores were identified. The method described and conditions worked out in this work are likely to be applicable to other plant species, and should be especially useful to professionals in universities, research institutions and agricultural industry. In the second part of this work, microspores were transformed by co-cultivation with Agrobacterium tumefaciens. Production of transgenic wheat with desired traits is of great importance. The efficiency in obtaining transgenic wheat plants is low and labor intensive, and it may take years to obtain the desired homozygous transgenic plant in the desired genotypic background.

Структурно - семантические особеннности спортивной фразеологии современного английского...
Пример: Co sola io race – утешительный заезд. Фразеологические выражения – это только обороты с буквальным значением компонентов. Включение образных пословиц в состав фразеологических выражений Н.М. Шанский считал нецелесообразным, так как в таком случае состав фразеологических выражений будет таким же разнородным, как и состав фразеологических единств. А.И. Смирницкий различает фразеологические единицы и идиомы . Фразеологические единицы – это обороты типа a clea sweep – полное избавление, победа спортивной команды, политической партии и др., shadow boxi g – «бой с тенью», борьба с воображаемым противником, ba i g average – личные достижения, успехи. Идиомы основаны на переносе значения, метафоре, ясно осознающейся говорящим. Их характерной чертой является яркая стилистическая окраска, отход от обычного нейтрального стиля. Примеры: Double cross – обман, надувательство (этимологически – состязание, в котором оба участника применяют запрещённые приёмы). Make a come back – оправляться после неудачи, взять реванш, обрести былую популярность.

Production For Graphic Designers Thames&Hudson
It also covers new workflows and spells out the many acronyms encountered by today' s designers. As well as covering print, it provides an authoritative guide to working in digital media, particularly the Internet. There are also addtional feature spreads on key graphic designers such as Bruce Mau, Paul Rand, Chris Ware and Pentagram. Computer technology has completely revolutionized the work of graphic designers, printers, and print production professionals. This revised fourth edition embraces all the new and emerging technologies in graphics and print production, comprehensibly explaining the prepress and printing processes from traditional letterpress to the latest on-press CtP (computer-to-plate) digital offset and on-demand colour printing. To keep pace with these far-reaching changes, "Production for Graphic Designers" is set firmly in the digital age.

Observation Based PDE Models for Stochastic Production Systems. Supply Chain Modeling Книга по Требованию Ali K.U.
In this book, continuum models of re-entrant production systems are developed that treat the ? ow of products in analogy to traffic ? ow. Specifically, the dynamics of material ? ow through a re - entrant factory via a parabolic conservation law is modeled describing the product density and ? ux in the factory. The basic idea underlying the approach is to obtain transport coefficients for ? uid dynamic models in a multiscale setting simultaneously from Monte Carlo simulations and actual observations of the physical system, i. e. a production factory.

What the Regular English Plural Can Tell Us about Language Comprehension, Production, and Meaning. Книга по Требованию Jennifer Z.
First, the slow, protracted course of acquisition is documented and evidence is presented that suggests children know much about when to use the English plural before they use it. Children' s comprehension of the English plural far surpasses their production, a difference that is linked to frequency effects from the environment. Children' s plural productions are shown to be tied to the meaning of the plural as children are more likely to produce the plural of nouns when there are more instances and when they are identical.
