Evaluation of the Premature Child Ache Profile-Revised (PIPP-R) e-Learning Unit: Immediate and also Continual Competency.
Alteration gradients were identified in both studied regions based on the distribution of diatoms, with the first axis of distance-based redundancy analyses (dbRDA) being related to nutrient enrichment and organic loads. Threshold Indicator Taxa ANalysis (TITAN) performed on diatoms sampled along environmental (dbRDA axis 1 and phosphate) and biological gradients (as Ecological Quality Ratio scores of classifications), pointed to lower than current Good/Moderate boundaries for phosphate maximum values (e.g. 22.5 and 71.6 μg L-1 for Galicia and the Balearic Islands, respectively) as well as for higher Good/Moderate boundaries for the MDIAT and IPS classifications. A 'transition group' of species was classified as sensitive or as tolerant depending on the regional nutrients range. Findings of the present study highlight the need to perform auto-ecological studies to increase the knowledge on regional diatoms and their optimal survival ranges across regions prior to adopt other non-regional diatom indices.One of the significant environmental threats in ports in recent years are carbon dioxide emissions generated by different activities carried out in these areas, which lead to Climate Change. In the maritime industry, this topic is getting more critical every day. The main cause of Climate Change is the emission of Greenhouse Gases (GHG). The total amount of GHG that are emitted both directly and indirectly by an activity are calculated by the following indicator the Carbon Footprint. The review of different case studies shows while in recent years many ports calculate their Carbon Footprint and report it, each port uses its own method and there is not any unified and complete method to calculate Carbon Footprint. This makes comparing results among different ports a difficult task and proves the need for such a method. Therefore, it has been developed a standardized tool to calculate GHG emissions in ports. The tool has been developed by using Excel and Visual Basic software and it is based on the WPCI (World Ports Climate Initiative) and IPCC (Intergovernmental Panel on Climate Change) guidelines and the GHG Protocol. Such tool is specifically designed so that port authorities can calculate their Carbon Footprint and report it accordingly. check details The tool has different steps taking into account the three scopes of emissions defined by the WPCI guideline for ports. Once developed, it was validated by a set of selected ports and environmental experts. The final aim is to distribute this tool to all ports and make it freely available.Anaerobic ammonium-oxidizing (anammox) bacteria play an important role in the nitrogen cycle by coupling ammonium and nitrite to produce dinitrogen gas (N2). Polymerase chain reaction (PCR) is a fast, simple, and sensitive method that is widely used to assess the diversity, abundance, and activity of the slow-growing bacteria. In this review, we summarize and evaluate the wide variety of PCR primers targeting the 16S rRNA gene and functional genes (hzo, nir, and hzs) of anammox bacteria for their effectiveness and efficiencies in detecting this group of bacteria in different sample types. Furthermore, the efficiencies of different universal high-throughput sequencing 16S rRNA gene primers in anammox bacteria investigations were also evaluated to provide a reference for primer selection. Based on our in silico evaluation results, none of the 16S rRNA gene primers could recover all of the known anammox bacteria, but multiple hzo and hzs gene primers could accomplish this task. However, uncertain copies (1-3 copies) of hzo genes were identified in the genomes, and the hydrazine oxidation reaction catalyzed by hydrazine oxidoreductases (HZOs) can also be catalyzed by other hydroxylamine oxidoreductases (HAOs) in anammox bacteria, which can potentially result in large deviations in hzo-based qPCR and RT-qPCR analyses and results. Therefore, the use of optimal primers targeting unique hzs genes are recommended, although the efficiencies of these newly designed primers need further verification in practical applications. This article provides comprehensive information for the effective and specific detection of anammox bacteria using specific primers targeting the 16S rRNA gene and functional genes and serves as a basis for future high-quality primer design.Alternate wetting and drying (AWD) irrigation in lowland rice cultivation increases water use efficiency and could reduce greenhouse gas (GHG) emissions compared to the farmers' practice of continuous flooding (CF). However, there is a dearth of studies on the impacts of water management on methane (CH4) and nitrous oxide (N2O) emissions in Bangladesh. Multi-location field experiments were conducted during the dry seasons of 2018 and 2019 to determine the baseline emissions of CH4 and N2O from rice fields and compare the emissions from AWD irrigation and CF. CH4 and N2O emissions were measured using the closed chamber technique and their concentrations were determined using a gas chromatograph. CH4 and N2O emissions varied across water management schemes and sites. AWD irrigation significantly (p less then 0.05) reduced cumulative CH4 emissions (37%, average across sites) without affecting grain yields compared to CF. The CH4 emission factor for AWD was lower (1.39 kg ha-1 day-1) compared to CF (2.21 kg ha-1 day-1). Although AWD irrigation increased seasonal cumulative N2O emissions by 46%, it did not offset reduced CH4 emissions. AWD reduced the total global warming potential (GWP) by 36% compared to CF. Similarly, GHG intensity (GHGI) in AWD was 34% smaller compared to that in CF. Emissions varied across sites and the magnitudes of seasonal cumulative CH4 and N2O emissions were higher at the Gazipur site compared to the Mymensingh site. AWD, which saves irrigation water without any yield penalty, could be considered a promising strategy to mitigate GHG emissions from rice fields in Bangladesh.Within urban agriculture (UA), integrated rooftop greenhouses (i-RTG) have great growth potential as they offer multiple benefits. Currently it is intended to improve environmental benefits by taking advantage of the water, nutrients and gases flows. On the other hand, solid waste (SW) generated by the UA is a new type of waste within cities that has not well been classified or quantified for its use. This could become a new problem for the waste management system within cities in the future, mainly the organic fraction. The objective of this research is to identify what type of i-RTG SW has the potential to be used from a circular economy (CE) perspective and propose a type of management for its material valorization. The results of the case study show that, of the SW generated in i-RTG, the biomass has the greatest potential to be used locally as an eco-material, particularly the tomato stems. Its use is proposed as a substrate for two experimental lettuce crops in i-RTG. The results show that tomato stems have a better yield as a substrate after a prewash treatment, since at first the values of electrical conductivity (EC) are very high with respect to the control substrate, which is expanded perlite.
