The IL-60 system is a transient universal vector system for expression and silencing in plants [1]. This vector has been derived from Tomato yellow leaf curl virus (TYLCV). The viral intergenic region (IR) is a non-coding short (314 b) sequence separating the viral sense-oriented genes from the complementary-oriented genes. IR carries the viral origin of replication as well as a promoter at eac...
one important issue that any material or test designer should bear in mind is to be careful about developing teaching and testing reading materials which would not be to the benefit of a group of readers or examinees and to the detriment of some others. one of the factors which may cause difference between the performances of english learners or test takers is the selection of reading tests wit...
Recently, research to consider the influences of iron loss has been made in the vector control of an induction motor. However, little work has been done in the area of a stator-flux-oriented control system of an induction motor. This paper investigates the effects of iron loss in the direct stator-flux-oriented control system of an induction motor, and proposes a control algorithm considering i...
Digital fingerprinting of multimedia data involves embedding information in the content signal and offers protection to the digital rights of the content by allowing illegitimate usage of the content to be identified by authorized parties. One potential threat to fingerprinting is collusion, whereby a group of adversaries combine their individual copies in an attempt to remove the underlying fi...
background: all humans are searching ways to promote mental health. mental health is vital for having a healthy life. some believe that mental health means lack of mental disorders. positive psychology emphasizes on issues such as hope, wisdom, creativity, spirituality, thinking about future and having purpose in life instead of psychopathology aspects. the purpose of this study was to investig...
Single-walled carbon nanotubes (SWNTs) with outstanding electronic, optical, mechanical and thermal properties are expected to be the most promising materials for next-generation energy as well as optical and electronic devices. However, the structure-controlled assembling of SWNTs to macroscale for various devices is still challenging. This study focused on the SWNT assemblies for improving th...
ErdH{o}s [On Sch"utte problem, Math. Gaz. 47 (1963)] proved that every tournament on $n$ vertices has a directed dominating set of at most $log (n+1)$ vertices, where $log$ is the logarithm to base $2$. He also showed that there is a tournament on $n$ vertices with no directed domination set of cardinality less than $log n - 2 log log n + 1$. This notion of directed domination number has been g...
Although there are a large number of contemporary software development processes/methodologies available to assist and guide software professionals in developing software systems, there is no specific process that can assist organizations in planning and managing their transition to this new work environment. As a result, there are still a large number of information technology (IT) organizatio...
The article raises the question of current state psychology as a science. It is suggested that heterogeneity subject and method caused its inorganic structure, which in turn created ground for permanent crisis this science, both theoretical practice-oriented terms. paradigm phenomenological philosophy considered an alternative coordinate reforming explained why approach implemented existential ...
Defined Single-Gene and Multi-Gene Deletion Mutant Collections in Salmonella enterica sv Typhimurium
We constructed two collections of targeted single gene deletion (SGD) mutants and two collections of targeted multi-gene deletion (MGD) mutants in Salmonella enterica sv Typhimurium 14028s. The SGD mutant collections contain (1), 3517 mutants in which a single gene is replaced by a cassette containing a kanamycin resistance (KanR) gene oriented in the sense direction (SGD-K), and (2), 3376 muta...
