Low Zn in staple food grains like rice is closely related to large scale Zn malnutrition in many countries of the World. Zinc biofortification of rice grains by some cost effective agronomic method is important for low income farmers. To explore the possibility of enhancing the bioavailability of Zn in rice grains besides higher yields of two cultivars, the combinations of varying Zn fertilizer doses with or without inoculation of rhizobacteria consortium under split plot design set up were evaluated in two years field trials. Microbial inoculation + 5 kg Zn ha-1 to I year rice crop resulted in the highest number of effective tillers, grain yields, Zn concentration and uptake in grains and straw and total Zn uptake in both years. Grain yield of rice during two years increased by 19.7-27.9 and 17.1-20.4 percent over control under treatments receiving microbial inoculation + 5 kg Zn ha-1 to I year rice and 5 kg Zn ha-1 alone to I year rice crop, respectively. The highest concentration of Zn (10.9-19.1 mg kg-1) and the lowest concentration of phytic acid (18.5-25.3 g kg-1) in dehulled rice grains were recorded with soil application of 5 kg Zn ha-1; however, the values were at par with those observed under microbial inoculation + 5 kg Zn ha-1 (12.0-17.0 mg Zn kg-1 and 19.2-26.9 g phytic acid kg-1). The percent utilization of soil applied Zn increased with microbial inoculation in both the years and it was relatively higher in NDR 359 as compared to PD 16.

Seagrass planting techniques have shown to be an effective tool for restoring degraded meadows and ecosystem function. In the Mediterranean Sea, most restoration efforts have been addressed to the endemic seagrass Posidonia oceanica, but cost-benefit analyses have shown unpromising results. This study aimed at evaluating the effectiveness of environmental engineering techniques generally employed in terrestrial systems to restore the P. oceanica meadows: two different restoration efforts were considered, either exploring non-degradable mats or, for the first time, degradable mats. Both of them provided encouraging results, as the loss of transplanting plots was null or very low and the survival of cuttings stabilized to about 50%. Data collected are to be considered positive as the survived cuttings are enough to allow the future spread of the patches. The utilized techniques provided a cost-effective restoration tool likely affordable for large-scale projects, as the methods allowed to set up a wide bottom surface to restore in a relatively short time without any particular expensive device. Moreover, the mats, comparing with other anchoring methods, enhanced the colonization of other organisms such as macroalgae and sessile invertebrates, contributing to generate a natural habitat.

Meta Analyses

The use of transfused blood, be it from an allogenic (donor) or autologous (same patient) source, is not a new treatment and in fact has been experimented with since the mid 1800s. The role of cell salvage and re-infusion of a patient’s own blood, however, has only begun to gain real popularity in the last 20 years, after the undertaking of several large scale meta-analyses which have shown that not only is autologous transfusion no less efficacious when compared to allogenic transfusion, but also potentially safer for a number of reasons. Autologous transfusion is also more cost effective overall and potentially quicker to initiate in an emergency situation. Despite the body of evidence to support the use of salvaged blood for transfusion, hesitation around its use still persists, with staff apprehension around set up of cell salvage equipment and general underestimation of intraoperative blood loss being key factors in its underuse.

Nanoparticles of Ru3Pd6Pt have been previously produced by different synthesis routes that involve high temperatures and relative high pressures and long time. The usage of a conventional microwave assisted synthesis reduces environmental risk impact as well as the cost effective production in large scale with minimum set up modifications. These features are the motivations for the use of microwaves in the synthesis of the Ru3Pd6Pt catalyst for PEM fuel cell applications to reduce the Pt loading. In this communication a tri-metallic electrocatalyst was produced by the reduction of the corresponding metallic salts, RuCl3, PdCl2, and H2PtCl6 in ethylene glycol using a modified conventional microwave device. Oxygen reduction reaction kinetic analysis results conducted to a Tafel slope, (-b = 41.2 ± 1.7 mV dec-1) at low overpotential, and exchange current density (i0 = 3.01 ± 0.39 × 10-5 mA cm-2) in 0.5M H2SO4. This electrocatalyst exhibited good performance and stability in a single H2/O2PEM fuel cell.

SUMMARYOver several decades agronomists have developed a mineral nutrition management method for perennial oil crops based on leaf analysis combined with reference field trials. This method has been used in a coconut plantation on the peats of the east coast of Sumatra to optimize mineral nutrition in a very short time, at minimum cost and with maximum reliability, through successive adjustments of the fertilizer schedules. Two reference trials were set up to study a wide range of mineral nutrients assumed to be deficient on this area. Further experiments were set up as new nutritional problems occurred at the plantation, and as soon as the first results were obtained from these two trials. In this way, the iron and copper deficiency problems at the plantation were dealt with satisfactorily taking an experimental approach. New experiments were set up recently to test the hypothesis of a silicon deficiency. The fertilization schedules for the commercial plantation were developed by successive adjustments based on the trial results. Leaf analysis data showed that the coconut palms in the commercial plots always complied with the experimental models. In addition to being rapid and reliable, this method was also cost-effective, especially when larger areas were involved.

This study presents the development of an Early Warning System (EWS) called EPIGONE focusing on the detection of dry weather overflows in the vicinity of throttle structures in sewer systems. Throttle structures are considered as vital parts of a sewer system as they are control sections limiting flow rates to a designed operational value. Because these structures are by definition prone to potential clogging or blockages, a close follow-up of the daily operation by an EWS facilitates increased vigilance or even alarm. Primary goal of EPIGONE is to alert operators and thus allow fast intervention in case of suspected failures of these structures within a settled timeframe. EPIGONE combines overflow water level measurements with rainfall radar information to determine Combined Sewer Overflow (CSO) activity during dry weather as this dual condition will indicate malfunctioning. This combination of measurements was found to be the most cost effective set-up to deploy on a large scale. Water level data are recorded and logged on-site and sent to a central controller via GSM/GPRS, where an algorithm determines dry weather overflow conditions. Rainfall radar data are used as criterion to decide on dry weather conditions. From there on alarms are sent out to multiple recipients via e-mail and/or text messages (SMS). Next to this, it is obvious that this system can also be used for ‘regular’ wet weather CSO monitoring.

Soil Function

<p>Global environmental changes and other anthropogenic impacts are rapidly transforming the structure and functioning of ecosystems worldwide. These changes are leading to soil degradation with an estimated 25 % of the global land surface being affected. The need to develop cost-effective large-scale solutions to restore disturbed landscapes becomes imperative to preserve biodiversity and achieve ecosystem functionality and sustainability. As part of a large-scale industry-academia partnership, we have developed a soil research program that aims to build knowledge and design strategies to restore degraded landscapes in Western Australia and other dryland regions worldwide. Within this program, a series of laboratory experiments, glasshouse studies, and field trials, have been conducted over the past six years to advance our knowledge on soil limitations and to provide solutions to enhance soil carbon levels and restore above and belowground biodiversity in restoration programs. These studies include (i) the analysis of the influence of multi-species planting on soil organic carbon and microbial activity and diversity (ii) the evaluation of soil physicochemical and microbiological indicators to assess functionality of restored soils in degraded semiarid ecosystems and (ii) the development of nature-based strategies based on bio-tools (e.g. inoculation of soil biocrust cyanobacteria) to increase soil carbon and enhance overall soil function. In this presentation we will highlight some key findings of these studies that include the benefits of combining diverse plant species and using native microbes and organic amendments for increasing soil carbon and promote soil function in reconstructed soil substrates. We will also discuss the potential applicability of these bio-technological approaches in landscape-scale restoration programs.</p>

This study fills a knowledge gap about low-income rural communities’ holistic management of multiple water resources to meet their multiple needs through multiple or single-use infrastructure. Six low-income rural villages in Limpopo Province were selected with a diversity in: service levels, surface and groundwater resources, public infrastructure (designed for either domestic uses or irrigation but multiple use in reality) and self-supply (people’s individual or communal investments in infrastructure). Focusing on water-dependent livelihoods and water provision to homesteads, distant fields and other sites of use, three policy-relevant patterns were identified. First, most households have two or more sources of water to their homesteads as a vital buffer to irregular supplies and droughts. Second, infrastructure to homesteads is normally for domestic uses, livestock and, for many households, irrigation for consumption and sale. Public infrastructure to irrigate distant fields is multiple use. Exceptionally, self-supply point sources to distant fields are single use. Water bodies to other sites of use are normally multiple use. As for large-scale infrastructure, multiple-use infrastructure is cost-effective and water-efficient. Third, in four of the six villages people’s self-supply is a more important water source to homesteads than public infrastructure. In all villages, water provided through self-supply is shared. Self-supply improves access to water faster, more cost-effectively and more sustainably than public services do. In line with international debates, self-supply is there to stay and can be supported as a cost-effective and sustainable complementary mode of service delivery. A last potential policy implication regards community-driven planning, design and construction of water infrastructure according to people’s priorities. This may sustainably harness the above-mentioned advantages and, moreover, communities’ ability to manage complex multiple sources, uses and multiple-use infrastructure, whether public or self-supply, as a matter of daily life.

In Sri Lanka a huge amount of flowers are cultivated. These flowers are used as decoration purposes or for offering to Buddha and God. A survey report reveals that 40% of the total productions of flowers are unsold and wasted everyday which are thrown in water or dumped which also creates water pollution as well as environmental pollution. These wasted flowers can be used in various ways & we can get wealth from waste materials. These wasted flowers are used in extraction of colourful dyes from these flowers and use it in textile industry for dyeing purposes and the residual water portion can be used as bio-fertilizers.Colourful dye can be extracted from flowers for dyeing textile fibre. These floral dyes are eco-friendly & it has no allergic action on skin like synthetic dye. Moreover the procedure is very cost-effective and depending on it small scale Industry as well as Large scale Industry can be set up. Keeping in view the importance of eco textiles and their demand in the national and international market and to overcome the problem of environmental pollution, allergic reactions to man- kind, and the present investigation was carried out to introduce to use floral dyes for dyeing of bleached cotton fabric and tested its colour fastness properties.

Roll Out

While large-scale changes in population behaviour are required to reduce the transmission of the severe acute respiratory syndrome coronavirus 2 virus, the emergency context is not conducive to the sort of careful communications planning that would normally be required to meet such a task. Rapid strategic communications planning in a pandemic by governments is, however, possible and necessary. Steps include setting up a dedicated communications task force, mobilising partners and resources, developing a creative brief and theory of change and overseeing the creation, testing, roll out and revision of content. In this short guide, we argue that a minimum of strategic planning can be undertaken rapidly, and that good use can be made of simple principles of behaviour change, even during pandemics. Our aim here is to provide a blueprint that governments and their partners, especially in low-income settings, can follow to design, coordinate and resource national communications efforts to combat the COVID-19 pandemic immediately and for the longer term.
