Transcriptomics has significantly grown as a functional genomics tool for understanding the expression of biological systems. The generated transcriptomics data can be utilised to produce a gene co-expression network that is one of the essential downstream omics data analyses. To date, several gene co-expression network databases that store correlation values, expression profiles, gene names and gene descriptions have been developed. Although these resources remain scattered across the Internet, such databases complement each other and support efficient growth in the functional genomics area. This review presents the features and the most recent gene co-expression network databases in crops and summarises the present status of the tools that are widely used for constructing the gene co-expression network. The highlights of gene co-expression network databases and the tools presented here will pave the way for a robust interpretation of biologically relevant information. With this effort, the researcher would be able to explore and utilise gene co-expression network databases for crops improvement.

Within hip-hop, MC (Master of Cermonies) battles are one of the most visible and potentially humiliating venues for demonstrating one’s verbal skill. Competitors face each other in front of an audience. Each has a minute to “diss” his or her opponent against a backdrop of rhythms produced by a DJ. Each participant’s performance generally consists of “freestyle” or spontaneously generated rhymes designed to belittle some aspect of the opponent’s appearance, rhyming style or place of origin, and ritual insults directed at his or her mother, sister, or crew. Opponents show good will by embracing afterwards. Ultimately the audience decides who wins by applauding louder for one opponent than the other at the end of the battle. Using the framework of interactional sociolinguistics (Goffman 1974, 1981), I will analyze clips from a televised MC battle in which the winning contestant was a White teenager from the Midwest called “Eyedea.” I will show how Eyedea and his successive African American opponents, “R.K.” and “Shells”, participate in the co-construction of his Whiteness. Eyedea marks himself linguistically as White by overemphasizing his pronunciation of /r/ and by carefully avoiding Black ingroup forms of address like “nigga” (c.f. Smitherman 1994). R.K. and Shells construct Eyedea’s Whiteness largely in discursive ways – by pointing out his resemblance to White actors, and alluding to television shows with White cultural references. Socially constructed racial boundaries must be acknowledged in these types of performances because Whiteness (despite the visibility of White rappers like Eminem) is still marked against the backdrop of normative Blackness in hip-hop (Boyd 2002). In a counter-hegemonic reversal of Du Boisian double-consciousness hip-hop obliges White participants to see themselves through the eyes of Black people. Hip-hop effectively subverts dominant discourses of race and language requiring MC battle participants to acknowledge and ratify this covert hierarchy.

Abstract This study explores the aims of the Nobel Banquet broadcast, produced by the Swedish public service company SVT and the Nobel Foundation. The study suggests that the programme can be viewed as a co-construction of science and media, and that the Nobel Foundation has three primary purposes: 1) to teach the audience about science; 2) to honour the laureates; and 3) to maintain and increase the status of the Nobel prize. SVT, for their part, has two main purposes: 1) to teach their audience about science, and 2) to entertain. The aims of the Nobel Foundation and SVT may seem disparate, but they are interrelated. At the same time, the subtleties between the entities create a tension that develops through mutual negotiations. The study ends with a discussion of two unexpected findings: 1) the shared, yet essentially differently-grounded aims of both parties to inform about science, and 2) the fact that their scientific content has increased in both absolute and relative terms over the years, a finding that questions notions of a continuous mediatisation of social institutions.

Additive main effects and multiplicative interaction (AMMI), as well as various AMMI-derived statistics, Genotype, and Genotype × Environment Interaction (GGE) models were employed on 24 sugarcane genotypes planted during two seasons (2017–18, 2018–19) under different induced salinity stress environments using saline water irrigation (iw) viz., E1 (Normal iw during crop season 2017–18), E2 (Normal iw during crop season 2018–19), E3 (4 dsm−1 ECiw during crop season 2017–18), E4 (4 dsm−1 ECiw during crop season 2018–19), E5 (8 dsm−1 ECiw during crop season 2017–18), E6 (8 dsm−1 ECiw during crop season 2018–19), E7 (12 dsm−1 ECiw during crop season 2017–18) and E8 (12 dsm−1 ECiw during crop season 2018–19) to assess the genotype by the environment interaction for the cane yield, commercial cane sugar (CCS) yield, number of millable cane (NMC), single cane weight (SCW), and pol % in juice. Individual and interactive effects of the genotype and environment for all the traits were significant. In the expression of total variability, the environmental contribution was higher for the cane yield (66.98%), CCS yield (67.60%), NMC (65.78%), and SCW (43.27%), whereas genotypic contribution was higher in the expression of pol% (82.48%). As per AMMI Stability Value (ASV), G14 (Co 13033), G23 (Co 15026), G7 (Co 05009), G17 (Co 13036), and G2 (Co 15025) were the most stable genotypes for the cane yield. Whereas as per GSI (genotype selection index), genotypes G24 (Co 15027), G21 (Co 15023), G23 (Co 15026), and G17 (Co 13036) were found most stable. The Sustainability Index (SI) of the cane yield (CY) and its contributing and CY-based computed traits were low for most of the genotypes, which indicates the negative impact of increased levels of irrigation-induced salinity in the expression of these traits. In the mean vs stability biplot analysis, G21 (Co 15023), G24 (Co 15027), G16 (Co 13036), G6 (Co 0238), and G20 (Co 14036) were found to be highly productive and stable genotypes for the cane yield. The superior and stable performance of early maturing notified varieties G21 (Co 15023) and G6 (Co 0238) for CY and CCS yield indicates that they will help the farmers to obtain sustainable income in saline soil conditions.

Abstract The quality of untreated water used by dry season vegetable growers determines the safety of the vegetables produced for human consumption. Traditionally, small scale vegetable farmers site their farms along banks of streams which gradually dry up during the dry season resulting in isolated pockets of ponds at different intervals along the path of the streams which are used by farmers to irrigate. A field experiment was initiated at Ibadan to ascertain the quality of irrigation water used to produce vegetables along Ona-stream during the dry season. Five isolated ponds and one locally dug well were sampled and analysed to ascertain the heavy metals status. Results of soil analysis from five farms (A - E) sited very close to the stream revealed high concentrations of heavy metals ranging from 0.96 to 2.34 mg kg-1 for Pb, 0.72 to 2.16 mg kg-1 for Cr and 0.30 to 0.92 mg kg-1 for Co while farmland F sited about 90m away from the stream was free of Pb, Cr and Co contaminants. Locally dug well F water was free of Cr, Co and Pb while isolated ponds had Cr, Co and Pb in the range of 0.01 to 0.23 mg kg-1 which is beyond safe consumption thresholds. There were strong correlations between heavy metals in water and vegetable for Cr (0.992**), Cd (0.599**), Ni (0.614*) and Pb (0.552**) indicating that the hygienic status of dry season vegetables is largely determined by the quality of irrigation water. In addition, all vegetables irrigated with untreated isolated ponds contained Cd, Pb and Ni concentrations above maximum permissible standard which could pose risk to human health. Therefore, farmers should be enlightened on the need to use hygienic water for irrigation. Construction of shallow wells on the farms instead of using contaminated stream water directly could be a better option for healthy and sustainable agriculture.

Necrotrophic pathogens are responsible for significant declines in crop yield and quality worldwide. During the infection process, a pathogen releases a series of secretory proteins to counteract the plant immune system, and this interaction of pathogen and host molecules determines whether the pathogen will successfully invade the host plant tissues. In this study, we adopted co-transcriptomic approaches to analyze the Lens ervoides–Stemphylium botryosum system, with a focus on 1,216 fungal genes coding for secretory proteins and 8,810 disease-responsive genes of the host 48, 96, and 144 h postinoculation, captured in two F9 recombinant inbred lines (RILs) displaying contrasting disease responses. By constructing in planta gene coexpression networks (GCNs) for S. botryosum, we found that the pathogen tended to co-upregulate genes regulating cell wall degradation enzymes, effectors, oxidoreductases, and peptidases to a much higher degree in the susceptible host LR-66-577 than in the resistant RIL LR-66-637, indicating that the promotion of these digestive enzymes and toxins increased S. botryosum virulence. Construction of cross-kingdom GCNs between pathogen and plant for the two RILs revealed that the co-upregulation of these fungal digestive enzymes and toxins simultaneously promoted a series of defense responses such as redox change, expression of membrane-related genes and serine/threonine kinase, and stress and disease responses in the susceptible RIL which was not observed in the resistant RIL, indicating that these activities exacerbated susceptibility to S. botryosum.

AbstractWe present a new approach to advance methods of climate change impact and adaptation assessment within a risk framework. Specifically, our research seeks to test the feasibility of applying impact models across sectors within a standard analytical framework for representing three aspects of potential relevance for policy: (i) sensitivity—examining the sensitivity of the sectors to changing climate for readily observable indicators; (ii) urgency—estimating risks of approaching or exceeding critical thresholds of impact under alternative scenarios as a basis for determining urgency of response; and (iii) response—determining the effectiveness of potential adaptation and mitigation responses. By working with observable indicators, the approach is also amenable to long-term monitoring as well as evaluation of the success of adaptation, where this too can be simulated. The approach focuses on impacts in climate-sensitive sectors, such as water resources, forestry, agriculture or human health. It involves the construction of impact response surfaces (IRSs) based on impact model simulations, using sectoral impact models that are also capable of simulating some adaptation measures. We illustrate the types of analyses to be undertaken and their potential outputs using two examples: risks of crop yield shortfall in Finland and impact risks for water management in the Vale do Gaio reservoir, Portugal. Based on previous analyses such as these, we have identified three challenges requiring special attention in this new modelling exercise: (a) ensuring the salience and credibility of the impact modelling conducted and outputs obtained, through engagement with relevant stakeholders, (b) co-exploration of the capabilities of current impact models and the need for improved representation of adaptation and (c) co-identification of critical thresholds for key impact indicators and effective representation of uncertainties. The approach is currently being tested for five sectors in Finland.

This chapter examines the early career of Ogle R. Gowan, the founder of the official Orange Order in Canada and his quest for respectability in political life and within the colonial establishment. Gowan introduced a more belligerent construction of Irish loyalist manliness than had existed prior to his arrival in Upper Canada. His public representation of Irishness centred on defending Protestantism, the fraternalism of the Orange lodge, and extreme loyalty to the Crown. The chapter traces his path from Co. Wexford to Upper Canada, and how he presented Orangeism as a vital transatlantic link between Ireland and the Canadas. The chapter also investigates how Gowan’s wife, Frances, was involved with his first cousin, James R. Gowan, and the implications which that close relationship had on James’ decision to abandon Orangeism in favour of a successful public career that his cousin Ogle was never able to attain.

Testo completoAbstract (sommario):
Biogas is a sustainable energy produced from biodegradable organic matter through anaerobic digestion. Biogas mainly contains methane (CH4) and carbon dioxide (CO2) and various contaminants, such as water vapor (H2O), ammonia (NH3), hydrogen sulfide (H2S), methyl siloxanes (MSs), nitrogen (N2), oxygen (O2), halogenated volatile organic compounds (VOCs), carbon monoxide (CO) and hydrocarbons whose presence largely depends on the source of biogas. The value of biogas is enhanced further by the production of organic manure as substitutes for chemical fertilizers in crop production. The vast range of applications makes biogas an attractive sustainable energy choice. Bioenergy generation capacity, mainly from biogas globally, has shown promising worth over non-renewable energy options; hence, its production has expanded rapidly during the previous two decades, from 42.38 Exajoules/year in 2000 to about 57.74 Exajoules/year in 2023, an increase of about 36.24%. This study presents the biogas production and potential improvement measures that include factors influencing the process and quality of biogas produces such as C/N (carbon nitrogen ratio, the pH, dilution of feedstock, composition and nutritive value of feedstock, residence period, mixing and stirring, temperature, presence of toxicants, loading time and redox conditions). The main barriers to biogas production and use include lack of technical know-how, lack of subsidies and incentives for biogas production and use. Access to appropriate and affordable biogas technologies, the development of a comprehensive policy on the construction and operation of bio-digesters as well as utilization of biogas and sales of biogas energy products and services are important for an increasing adoption of biogas.

Basic Technical Details: Displacement: 5000 tonnes; Width: 23.2m; Height: 6.6m; Length: 65m; Draught: 3.5m; Processing Throughput: 7000m3/year. In October 1993, the Governments of Japan and the Russian Federation signed an Intergovernmental Agreement to reduce the threat of nuclear weapons in the Former Soviet Union. Towards achieving this goal, the Japanese Government had initially allotted $100 million towards, which was increased to $200 million in 1999. The main objective of the Suzuran project is to process low-level liquid radioactive waste, which has been in storage for some years, and prevent it from being dumped into the seas shared by Japan and Russia. The construction and completion of the Suzuran, in the Russian Far East, is the brainchild of the Japanese Government, and is the first successful international project of its kind in Russia. Suzuran neatly solves the problem of making safe the liquid radioactive waste being derived from general purpose and missile nuclear submarines of the Russian Pacific Fleet as they are decommissioned and dismantled. The project was administered by the Technical Secretariat of the Japan-Russia Committee for Co-operation on Reducing Nuclear Weapons, who appointed Crown Agents as their agent and RWE NUKEM as their Technical Consultants to manage the project on a day to day basis and oversee the tender, construction and commissioning. This project is unique and complex in that it is, in reality, two projects. Firstly, the construction of a sea-going barge and, secondly, the construction of a complex radioactive liquid waste processing facility. Changes in the Russian Radiation Regulations during the course of the project, required the design to be altered significantly; for example, the facility had to be mounted within the structure of the vessel. Numerous regulators, design and testing institutes were involved throughout the project, to ensure it complied with both Russian and International regulations. Suzuran is the only floating complex that can operate independently for up to 30 days away from base. It is also exceptional in having the greatest throughput capacity of any project of its type and in being fully actively commissioned and licensed to operate, as part of the original contract. Other similar projects, which have a lower throughput and are land-based, have been handed over prior to completion of active commissioning. The international project was particularly complex since it involved not only Japan and Russia but also a Japanese-American contractor, who subcontracted the construction work to Russian shipyards. The Amurski Shipyard at Komsomolsk-na-Amur constructed the Vessel and the processing Facility was constructed in America and shipped to Russia where it was installed on the Barge. The Barge was then towed down the Amur River and down the Russian East Coast to Bolshoi Kamen where it was inactively and actively commissioned. The completed Barge was completed and is now operating, following a one-year warranty period. The project required everyone’s close co-operation and understanding. Particularly onerous was the need to comply with comprehensive Russian regulations, both for sea-going vessels as well as for nuclear facilities. This is a success story in itself. The official Handover ceremony of Suzuran was held in November 2000 and is now operating at the Far Eastern Shipyard, Zvezda. This paper will describe the history and process involved in establishing the Barge project for the treatment of Low Level Liquid Radioactive Waste.

Abstract Steel is the most common construction material in the Oil & Gas industry, and it begins to rust the day it is cast. This observation raises several challenges for the asset integrity and life extension of all offshore units. Therefore, for the ageing FPSOs (>10 years), frequent and costly structural maintenance operations in hazardous environment may be required to repair their hull. While a standard ship can go to dry-dock for “crop and renew” maintenance operations through standard hot works techniques, a permanently moored asset has to be maintained in situ. The challenge is to perform these offshore structural maintenance operations with no production disruption while maximizing safety even for the most stressed areas such as a mid-ship deck plating. COLDSHIELD, a co-development between COLD PAD, TOTAL and IFP Energies nouvelles, has been set up to meet this very challenge. This innovative alternative to “crop and renew” is covered by approval certificate from Class. COLDSHIELD stops the corrosion and restores hull structural strength. Two industrial applications have been performed so far. Among the steps to be taken to demonstrate that such repair can be considered as permanent, it was mandatory to characterize the fatigue behavior of this reinforcement solution. While the fatigue behavior of steel has been an important research topic since the early eighties of the last century, its understanding for bonded composite materials is still at its infancy. Indeed, for the time being there is — to our knowledge — no S-N curve for structural bonded reinforcements. Full scale coupon specimen fatigue tests of the structural bonded reinforcements were conducted by COLD PAD, third-partied by Bureau Veritas and in collaboration with two laboratories (private and public) in order to study the adhesive fatigue. A statistical analysis was performed according to international standards. The resulting S-N curve is fit for industrial fatigue design. It demonstrates a comfortable fatigue strength (S-N curve presenting a slope of 9). This paper presents the results of a fatigue life assessment campaign of COLDSHIELD including the experimental setup, the fatigue test results, and the numerical analyses. It details the reason why the design is compatible with a stress-based approach. It also explains the conclusions that can be derived in terms of fatigue life for a deck repair campaign.

Blum, Abraham, e Henry T. Nguyen. Molecular Tagging of Drought Resistance in Wheat: Osmotic Adjustment and Plant Productivity. United States Department of Agriculture, novembre 2002. http://dx.doi.org/10.32747/2002.7580672.bard.
Testo completoAbstract (sommario):
Drought stress is a major limitation to bread wheat (Triticumaestivum L.) productivity and its yield stability in arid and semi-arid regions of world including parts of Israel and the U.S. Currently, breeding for sustained yields under drought stress is totally dependent on the use of yield and several key physiological attributes as selection indices. The attempt to identify the optimal genotype by evaluating the phenotype is undermining progress in such breeding programs. Osmotic adjustment (OA) is an effective drought resistance mechanism in many crop plants. Evidence exists that there is a genetic variation for OA in wheat and that high OA capacity supports wheat yields under drought stress. The major objective of this research was to identify molecular markers (RFLPs, restriction fragment length polymorphisms; and AFLPs, amplified fragment length polymorph isms) linked to OA as a major attribute of drought resistance in wheat and thus to facilitate marker-assisted selection for drought resistance. We identified high and low OA lines of wheat and from their cross developed recombinant inbred lines (RILs) used in the molecular tagging of OA in relation to drought resistance in terms of plant production under stress. The significant positive co-segregation of OA, plant water status and yield under stress in this RIL population provided strong support for the important role of OA as a drought resistance mechanism sustaining wheat production under drought stress. This evidence was obtained in addition to the initial study of parental materials for constructing this RIL population, which also gave evidence for a strong correlation between OA and grain yield under stress. This research therefore provides conclusive evidence on the important role of OA in sustaining wheat yield under drought stress. The measurement of OA is difficult and the selection for drought resistance by the phenotypic expression of OA is practically impossible. This research provided information on the genetic basis of OA in wheat in relations to yield under stress. It provided the basic information to indicate that molecular marker assisted selection for OA in wheat is possible. The RIL population has been created by a cross between two agronomic spring wheat lines and the high OA recombinants in this population presented very high OA values, not commonly observed in wheat. These recombinants are therefore an immediate valuable genetic recourse for breeding well-adapted drought resistant wheat in Texas and Israel. We feel that this work taken as a whole eliminate the few previous speculated . doubts about the practical role of OA as an important mechanism of drought resistance in economic crop plants. As such it should open the way, in terms of both concept and the use of marker assisted selection, for improving drought resistance in wheat by deploying high osmotic adjustment.
