Komentar Bagikan
Ahmed Mostafa Ahmed Amin

Local scouring action downstream of clear over-fall weirs associated with three-dimensional turbulent flow field is a common morphological problem in mobile channel bed. The objective of this study was to assess and quantify the impact of hydraulic structural measures (double lines water jets) on minimizing the scour-hole dimensions downstream of a Fayoum type weir. Ninety runs were conducted c…

A. Sofi [et al.]

The flexural behaviour of plain and fibre-reinforced pond ash concrete (FRC) beams under monotonic loading condition was analysed. Sixteen beams reinforced with top and bottom longitudinal deformed steel bars and transverse steel stirrups were tested. The beams were cast using three different percentages of pond ash, namely, 10%, 20% and 30% by weight of cement. Grooved type steel fibres were i…

Mahmood Shafai Bejestan [et al.]

Over the past few decades, the cause of many bridge failures has been reported to be abutment scour. A large number of studies have been conducted to develop countermeasures to ensure the safety of existing bridges. A submerged vane is a measure that has recently been studied and found to be a promising scour mitigation technique for river bank erosion. Therefore, the main purpose of this study…

The Manning’s equation is commonly used to calculate discharge and mean velocity of the uniform flows. According to experimental data, Manning’s equation with constant Manning’s coefficient overestimates the discharge of second-kind channels (channels with a closing top-width),under the partially full flow. This problem can be solved by altering the Manning’s coefficient depending on th…

Generation contingencies in a power system lead to under-frequency and low voltages owing to active and reactive power deficiencies. Load shedding is considered as a last alternative to avoid the cascaded tripping and blackout in power systems during generation contingencies. It is essential to optimize the amount of load to be shed in order to prevent excessive load shedding. To minimize load …

Komentar Bagikan
Paweena SALEETHONG [et al.]

Exogenous application of spermidine (Spd) has been reported to modulate physiological processes and alleviate salt-induced damage to growth and productivity of several plants including rice. Employing a proteomic approach, we aimed at identifying rice leaf and grain proteins differentially expressing under salt stress, and in response to Spd prior to NaCl treatment. A total of 9 and 20 differen…

XU Xia [et al.]

The accumulation of pigments affects the color of rice hulls while only limited information is known about its underlying mechanisms. In the present study, a rice brown hull 6 (bh6) mutant was isolated from an ethane methyl sulfonate (EMS)-induced IR64 mutant bank. Brown pigments started to accumulate in bh6 rice hulls after heading and reached a higher level in mature seeds. Some major agronom…

A Practical Guide to Supramolecular Chemistry
Komentar Bagikan
Peter J. Cragg

Supramolecular chemistry – the branch of chemistry associated with the formation of complex multimolecular entities from relatively simple molecular components – has been a major research theme over the past four decades. Researchers were provided with a unifying vision of the field following the award of the 1987 Nobel Prize in chemistry to three of its pioneers: Jean-Marie Lehn, Donal…

S. J. S. RAMA DEVI [et al.]

To develop and characterize introgression lines for leaf and neck blast resistance, 326 introgression lines were developed using various accessions of six different AA genome wild species in the genetic background of elite Indian varieties like PR114 and Pusa 44 and were screened for blast resistance. Stringent phenotyping coupled with genotyping using gene based markers led to the identificati…

Komentar Bagikan
Rukmini MISHRA [et al.]

Despite significant yield advantage over inbred rice, the adoption rate of hybrid rice in India is very low due to the high seed cost and poor quality of the produce. To alleviate the problem, we initiated a doubled haploid (DH) breeding approach to develop new lines from two elite indica rice hybrids (CRHR5 and CRHR7) through rapid fixation of homozygosity in the recombinants. In vitro culture…

Bhausaheb PAWAR [et al.]

This study was conducted to evaluate the effects of proline and glutamine on in vitro callus induction and subsequent regeneration and to develop a reproducible and highly efficient plant regeneration protocol in four rice genotypes, viz. Pawana, Jaya, Indrayani and Ambemohar. Considerable variation in response to plant growth regulators and amino acid supplements used was observed in all the f…

XIANG Chao [et al.]

To dissect the genetic basis of low phosphorus tolerance (LPT), 114 BC2F4 introgression lines (ILs) were developed from Shuhui 527 and Minghui 86 (recurrent parents), and Yetuozai (donor parent). The progenies were tested for 11 quantitative traits under three treatments including normal fertilization in normal soil (as control), normal fertilization in barren soil and low phosphorus stress in …

Identification and Cloning of Tillering-Related Genes OsMAX1 in Rice
Komentar Bagikan
WANG Xiu-mei [et al.]

Tillering is an important agronomic trait which has a direct impact on plant type and grain yield. Strigolactones are a class of important phytohormones regulating rice tillering. ATMAX1 is an important gene involved in strigolactone biosynthesis through encoding the protein P450 in Arabidopsis. Based on sequence BLASTp, we identified five homologous genes of ATMAX1 in rice, i.e., OsMAX1a, OsMA…

S. J. KALE [et al.]

An attempt was made to determine the qualitative changes in basmati rice (Pusa Basmati 1121,PB1121) during soaking at 40 °C to 80 °C. Soaking temperature had significant effect (α = 0.01) on chemical composition, glycemic index and starch characteristics of rice. Starch content, apparent amylose content, crude protein content and crude fat content in un-soaked rice were found to be 73.24%,27…

ZHANG Ya-fang [et al.]

Narrow genetic background is a key limiting factor in breeding stable high-yielding rice. The introduction and utilization of international rice core germplasm is an important way to increase the genetic diversity of domestic rice varieties. We conducted a genome-wide association study on 5 panicle traits of 315 rice accessions introduced from the international rice micro-core germplasm bank. B…

K-Domain Splicing Factor OsMADS1 Regulates Open Hull Male Sterility in Rice
Komentar Bagikan
SUN Lian-ping [et al.]

We identified the rice floral organ development mutant, termed as open hull and male sterile 1 (ohms1), from the progeny of the indica restorer line Zhonghui 8015 treated with 60Co γ-ray irradiation. The ohms1 mutant exhibited an open hull and lemma- and palea-like structure conversion between the anthers and stigma, which resulted in the ohms1 mutant spikelet showing ‘tridentate lemma’. T…
