Distant Drums And Thunderous Cannon: Sounding Authority In Traditional Malay Society
Pre-modern Malay society was intensely oral and aural, and the texts that are
now read were always intended for group recitation and performance. Studies of
auditory history in other societies have emphasised that in the past, sounds were
experienced differently from the way they are heard today. At the very basic level,
thunder—the voice of the heavens—established the benchmark and the basis for
comparison for awe-inspiring sounds that humans could attempt to replicate,
notably in the beating of drums and the firing of cannon. Together with the noseflute, the drum is the oldest and most indigenous Malay instrument, and the drums
that were included in royal regalia were accorded personalities of their own
Book Review – The Factory Of The English East India Company At Bantam, 1602–1682
David Kenneth Bassett (1931–1989) spent several years teaching at the
University of Malaya (which was then in Singapore), and at the same
institution following its relocation to Kuala Lumpur. In 1965 he was
appointed to the faculty of the University of Hull, where he served as
Director of the Centre for South-East Asian Studies until 1988, a year
before his premature death in 1989 at the age of 59. Bassett's career thus
spans a formative period in Southeast Asian studies. In 1950, a Department
of Southeast Asian History was established in the School of Oriental and
African Studies (SOAS) in London, and two years later Bassett entered the
programme as a doctoral candidate. His dissertation, "The Factory of the
East India Company at Bantam 1602–1682," was submitted in 1955, the
same year that D.G.E. Hall published his History of South-East Asia, which
represents the first attempt at a regional coverage. As one of the early
SOAS graduates, Bassett was a pioneer in the embryonic field of Southeast
Asian studies, continuing on to become a world-renowned specialist on
European trade in the Malay world in the seventeenth and eighteenth
centuries
Phosphorylation stoichiometries of human eukaryotic initiation factors.
Eukaryotic translation initiation factors are the principal molecular effectors regulating the process converting nucleic acid to functional protein. Commonly referred to as eIFs (eukaryotic initiation factors), this suite of proteins is comprised of at least 25 individual subunits that function in a coordinated, regulated, manner during mRNA translation. Multiple facets of eIF regulation have yet to be elucidated; however, many of the necessary protein factors are phosphorylated. Herein, we have isolated, identified and quantified phosphosites from eIF2, eIF3, and eIF4G generated from log phase grown HeLa cell lysates. Our investigation is the first study to globally quantify eIF phosphosites and illustrates differences in abundance of phosphorylation between the residues of each factor. Thus, identification of those phosphosites that exhibit either high or low levels of phosphorylation under log phase growing conditions may aid researchers to concentrate their investigative efforts to specific phosphosites that potentially harbor important regulatory mechanisms germane to mRNA translation
Genetic variation and possible origins of weedy rice found in California.
Control of weeds in cultivated crops is a pivotal component in successful crop production allowing higher yield and higher quality. In rice-growing regions worldwide, weedy rice (Oryza sativa f. spontanea Rosh.) is a weed related to cultivated rice which infests rice fields. With populations across the globe evolving a suite of phenotypic traits characteristic of weeds and of cultivated rice, varying hypotheses exist on the origin of weedy rice. Here, we investigated the genetic diversity and possible origin of weedy rice in California using 98 simple sequence repeat (SSR) markers and an Rc gene-specific marker. By employing phylogenetic clustering analysis, we show that four to five genetically distinct biotypes of weedy rice exist in California. Analysis of population structure and genetic distance among individuals reveals diverse evolutionary origins of California weedy rice biotypes, with ancestry derived from indica, aus, and japonica cultivated rice as well as possible contributions from weedy rice from the southern United States and wild rice. Because this diverse parentage primarily consists of weedy, wild, and cultivated rice not found in California, most existing weedy rice biotypes likely originated outside California

The purpose of this research is to know the result of large production loss, to analyze the probability and impacts of lost production at post harvest process of the fresh fruit bunches (FFB) paml oil from on land until to palm oil factory (POF). Research was done by survey at Pagaruyung Village. Data were collected from 30 small-holders palm oil farmers using purposive sampling. Analysis of the results obtained shows that the loss of production the fresh fruit bunches (FFB) palm oil in post harvest process as 4,91 percent/2ha/month, that loss of production at land as 0.93 percent, at TPH ( FFB raw ) as 0.36 percent, at TPH (FFB) as 0.36 percent and at palm oil factory (Sorting plant process) as 2.93 percent. Probability of the loss production at land as 25.18 percent, at TPH (FFB raw and FFB) as 23.18 percent and 23.24 percent, at palm oil factory (sorting plant process) as 18.79 percent. The impact of the losses arising from the loss of post-harvest TBS is Rp 190.137,97/2ha/month and if combined for one year will reach Rp 2.281.655,60
Dynactin-dependent cortical dynein and spherical spindle shape correlate temporally with meiotic spindle rotation in Caenorhabditis elegans.
Oocyte meiotic spindles orient with one pole juxtaposed to the cortex to facilitate extrusion of chromosomes into polar bodies. In Caenorhabditis elegans, these acentriolar spindles initially orient parallel to the cortex and then rotate to the perpendicular orientation. To understand the mechanism of spindle rotation, we characterized events that correlated temporally with rotation, including shortening of the spindle in the pole-to pole axis, which resulted in a nearly spherical spindle at rotation. By analyzing large spindles of polyploid C. elegans and a related nematode species, we found that spindle rotation initiated at a defined spherical shape rather than at a defined spindle length. In addition, dynein accumulated on the cortex just before rotation, and microtubules grew from the spindle with plus ends outward during rotation. Dynactin depletion prevented accumulation of dynein on the cortex and prevented spindle rotation independently of effects on spindle shape. These results support a cortical pulling model in which spindle shape might facilitate rotation because a sphere can rotate without deforming the adjacent elastic cytoplasm. We also present evidence that activation of spindle rotation is promoted by dephosphorylation of the basic domain of p150 dynactin

The Role of Lipids in the Formation of Beneficial Interactions Between Plant Roots and Soil Microbiota under Heat Stress
Climate change, which is characterized by the rise of global atmospheric temperatures known as global warming, has serious detrimental effects on crop production because of the direct influence of elevated temperature on plant development. One novel strategy to increase crop productivity while mitigating heat stress is the use of soil microbes, which is slowly gaining popularity because of its low-cost approach, availability, sustainability, and quick turnover. Specific soil microbes can form symbiotic relationships with the roots, whose beneficial effects on plant growth and development, as well as on plant responses to biotic and abiotic stresses, lead to improved plant performance. The plant-microbe interaction is complex and involves below-ground communication, followed by modifications of molecular, biochemical, and morphological processes in the plant. Plant roots display extreme plasticity in adapting to a range of environmental stimuli and are therefore important indicators of plant-level responses to microbial colonization, via changes in architecture and metabolic processes. Lipids, which are essential constituents of the plasma membrane with diverse functions in cellular processes and homeostasis, have been proposed to play significant roles in the rhizosphere. Because heat stresses have a profound effect on membrane stability and lipid composition, rising global temperatures are likely to impact the formation of plant-microbe symbiosis.
This study aimed to characterize and quantify the bacteria-induced growth promotion and heat tolerance in plants, and to investigate how plant root lipid profiles are altered under both bacteria and high-temperature conditions. For that, advanced phenotyping and lipidomics technology were employed to monitor plant responses to developmental and environmental changes. By using the high-resolution, high-throughput phenotyping platform GrowScreen-Agar II, an open-top plant-bacteria co-cultivation system was optimized utilizing the model plant Arabidopsis thaliana and the plant-growth-promoting rhizobacteria (PGPR) Paraburkholderia phytofirmans PsJN. This allowed for in-depth, tissue- and time-specific root-and-shoot morphological trait characterization, which elucidated the dynamics of bacterial promotion on plant growth. We have quantified the magnitude of bacterial-induced plant stimulation between ambient and elevated temperatures, confirming the excellent benefit of the PGPR in ameliorating the adverse effects of heat stress. These morphological traits were also associated with the root lipid profile using state-of-the-art lipidomics technology, which revealed specific lipid species and their functions in this tripartite interaction. Knowledge gained from this study, besides being fundamental in the understanding of plant-microbe interactions, can also inform research agenda of future directions for microbial studies as potential agricultural and biotechnological solutions in the endeavor to address global food security under climate change
