Abstract Background Benzobicyclon (BBC) is a β-triketone herbicide (bTH) used in rice paddy fields. It has the advantages of high efficiency, low toxicity, crop safety, and good environmental compatibility, shows efficacy against weeds resistant to other types herbicides. However, as some important indica varieties are susceptible BBC, BBC currently only registered applied japonica cultivation ...

Background: Selection of genotypically superior parents is most challenging task for the development potential hybrids. In conventional plant breeding, magnitude heterosis and inbreeding depression has been proved very effective in identifying vigorous parental combinations. Methods: The present investigation was carried out to study heterosis, residual forty sorghum crosses (F1s F2s) obtained ...

Sorghum is the important cereal crop around the world and hence understanding and utilizing the genetic variation in sorghum accessions are essential for improving the crop. A good understanding of genetic variability among the accessions will enable precision breeding. So profiling the genetic diversity of sorghum is imminent. In the present investigation, forty sorghum accessions consisting o...

In this paper a Dynamic Voltage Restorer (DVR) is used for power quality improvement on transmission side for the voltage regulation, grid stabilization and efficient utilization. The DVR normally installed between the source voltage and critical or sensitive load. The vital role of DVR depends on the efficiency of the control technique involved in switching circuit of the inverter. The DVR is ...

Dynamic Voltage Restorer (DVR) is used in power distribution system to protect sensitive loads in voltage disturbances. The performance of DVR is related to the adopted configuration and control strategy used for inverters. In this paper, an asymmetrical voltage-source inverter controlled with fuzzy logic method based on hysteresis controller, is used to improve operation of DVR to compensate v...

While early FACTS devices consisted mainly of thyristor-controlled/switched RLC/transformer components, the newer generation is based on the self-commutated voltage-source power converter. Different shunt FACTS devices, namely Static VAR compensator (SVC) and Static Synchronous Compensator (STATCOM), Dynamic voltage restorer (DVR) in transmission line using the actual line model. This paper des...

Mitochondrial gene expression was characterized during meiosis in sunflower anthers. In situ hybridization experiments showed that there was a marked accumulation of four mitochondrial gene transcripts (atpA, atp9, cob, and rrn26) in young meiotic cells. This pattern of transcript accumulation was only detected for mitochondrial genes and not for transcripts of two nuclear genes (atpB and ANT) ...

Power quality (PQ) is a key issue, particularly for technologically advanced process equipment, whose performance mainly depends on the of supply. Problems with PQ such as voltage swells/sags, interruptions, and harmonics are defined by any voltage, current, or frequency abnormalities causing damage failure end-user equipment. Outages interruptions lead to malfunctioning equipment sensitive loa...

In gynodioecious species, females and hermaphrodites coexist and the genetics of sex determination is usually nuclear cytoplasmic. Maintaining nuclear-cytoplasmic gynodioecy requires polymorphism for the feminizing genes (contained in the mitochondria) and the genes that restore male fertility (contained in the nucleus). This complex polymorphism depends, in part, on there being negative pleiot...
