Orthorectification Tests Continued... Formosat-2 Orthorectification Of Formosat-2 Data for use in The Common Agricultural Policy Control with Remote Sensing Programme
FORMOSAT-2 (NSPO, Taiwan) was launched on 21st of May, 2004. FORMOSAT-2 was programmed as Very High Resolution backup sensor in the CwRS campaign for the first time in 2006 [Ref 1]. Acquisition success rate has been high since it was introduced due to its high (daily) revisit capacity, but difficulties were initially encountered to reach the required location accuracy in production of orthorectified imagery. This resulted in a 1st study (2006) where FORMOSAT-2 imagery over Sofia (BG) was assessed; 4 software suites were tested on this image with low off-nadir viewing angle [Ref 2]. Results were promising, demonstrating that it is possible to perform good orthorectification using standard software packages reaching results inside the CwRS requirements for such imagery (location accuracy preliminary set to 3.5m RMSE1D). In this 2nd study (2007) the aim has been to assess the effect of large off-nadir angles on the accuracy of the orthorectification, and to define the optimal number of GCPs to be used when orthorectifying FORMOSAT-2 images on a routine basis. Results of orthocorrection of 4 images of different off-nadir angles (along/across angles), over 2 sites in France and Bulgaria, using 4 different sw suites (PCI, ERDAS Imagine, PRODIGEO, and Keystone SIPOrtho,) and with varying number of GCPs are discussed. The results are consistent with theoretical expectations; x error increases when across angle (roll) increases, the y error increases when along angle (pitch) increases. Basically the accuracy of 5m RMSE1D is reached with all tested softwares, the 3.5m RMSE1D accuracy may be reached if limits are placed on the acquisition angles. Concerning the GCP requirement a total of minimum 10 GCPs should be used: four GCPs spread in the corners of the scenes, the others evenly distributed, and clearly visible.JRC.G.3-Agricultur

Biotesting as a modern assessment method of the aquatic environment Biofloc quality
Studies were conducted to determine the biofloc media toxicity degree to hydrobionts by biotesting. Environment variability in which biocenosis biofloc is formed can cause optimal C/N ratio values violations in a closed water system, which is considered a critical factor affecting the formation rate of microbial communities and species ratio in them. Test objects use in this study showed no toxic effects on the bioindicator in the environment created by the bacterial communities that make up the Biofloc system. Of course, the data obtained cannot be considered exhaustive, but it should be noted that aquatic plant use as a bioindicator provides new opportunities for developing biofloc systems potential. The BFT-systems principle is to stimulate the natural growth of macroaggregate flocs, enhance culture water self-nitrification. A prerequisite for the flocs’ functioning as a biofilter analogue, along with supporting them in suspension, is the presence of an easily digestible organic carbon source, as the cultures of bacterial microorganisms in the base of flocs are heterotrophic
Implementation of Efficient Energy Policy in Russia: Energy Consumption Monitoring and Problem Analysis
The implementation of an efficient energy policy in Russia as an integral part of the social and economic strategy as a whole gives a high profile to the issues of energy consumption monitoring. The importance of the energy sector to the industrial development of all Russian regions requires close attention to the accounting and rational use of energy resources in order to reduce the energy dependence of all industries and make Russian economy less energy-intensive whilst more energy-efficient. The analysis of strategic documents in the field of energy saving proves the importance of the Russian Federation, which is one of the leaders of the world energy sector. The purpose of the article is to study the energy aspects of energy consumption in the regions of the Russian Federation, to conduct their comparative analysis and evaluation, and to identify problems in the supply of energy resources. The methods of research applied to study this problem include data collection and synthesis methods; a balance method; a time-series method; tabular and graphical methods of the study results visualization. The article presents the dynamics of electricity consumption in the regions of the Russian Federation broken down by federal districts and macro-regions set out in the Russian Federation spatial development strategy; also, the consumption balance by types of energy resources is provided for various fuels. In addition, it provides a brief description of the Russian integrated power system operation reflecting the generation and consumption of electricity among the main power systems of the country. Based on the analysis of Russia's energy development forecast, using scenario approaches, the article concludes that the energy efficiency of the national economy requires improvement and there is a need to implement energy-saving projects. The information contained herein is of practical value for the professionals involved in the analysis and evaluation of energy resources consumption and assessment of their contribution to the national economy. The results of the study reveal fundamental differences in the consumption and use of energy resources throughout Russia's regions.
Keywords: energy resources monitoring, energy consumption, energy security, energy saving, energy strategy.

Marine heatwaves and cold spells in the Northeast Atlantic: what should the UK be prepared for?
Up to now, the UK has avoided major marine heatwaves (MHWs) that cause severe damage to marine ecosystems and the blue economy. However, an unprecedented in its intensity, though short-lived, MHW occurred in UK waters in June 2023. This event sounded an alarm bell, highlighting gaps in our understanding of MHW characteristics and their potential future impacts in the UK. Here, we use a combination of remote sensing data and model output to characterise MHWs and Marine Cold Spells (MCSs) around the UK and the wider North Atlantic, and to assess the potential for concurrent biogeochemical extreme events. Results indicate that across the wider North Atlantic, the UK is not a hot spot for MHWs or MCSs but, regionally, the southern North Sea experiences the most activity. This is also the location of extreme chlorophyll-a concentrations, here termed blue waves (low chlorophyll-a) and green waves (high chlorophyll-a). However, there is not a very pronounced relationship between temperature and chlorophyll-a extremes, which may be impacted by the exact location, drivers and season of occurrence. In contrast, the southern North Sea and English Channel may experience a MHW and low near-bottom oxygen compound events year-round, which, due to the combination of thermal stress and reduced oxygen availability, may negatively impact benthic marine ecosystems. While MHWs in UK waters do not appear to be as long-lasting or intense as other well-documented events around the world, they are projected to increase. Thus, the UK has a unique opportunity to learn from other nations and so develop robust and comprehensive policies to increase preparedness and response capability for future extreme events
Recrystallization of CaCO3 submicron magnetic particles in biological media
Background and Objectives: The development of magnetic theranostics is associated with the determination of the behavior of magnetic carriers in biosimilar media. In this work, we analyze the formation of different crystalline phases from magnetic mineral submicron calcium carbonate particles during incubation under conditions of cell cultivation in vitro for 3 days. The study of mineralmagneticsubmicron particles recrystallization was analyzed by XRD and electron scanning microscopy. The shape of calcium carbonate particles begins to change from elliptical to spherical under cell culture cultivations. As the amount of magnetite nanoparticle particles in calcium carbonate increases, the recrystallization process is faster with fallout of calcite, vaterite and magnetite phases. Materials and Methods: Scanning electron microscopy, processing of results using a self-written Python code, XRDwere utilized in this study. Results: The study of the process of recrystallization of magnetic mineral particles shows has shown that increasing the content of magnetic carriers leads to accelerated recrystallization of particles with simultaneous precipitation of calcite, vaterite and magnetite phases. Conclusion: Magnetic mineral submicron calcium carbonate particles are promising targets for theranostics with the self-destruction property in biological environments
Interspecific Proteomic Comparisons Reveal Ash Phloem Genes Potentially Involved in Constitutive Resistance to the Emerald Ash Borer
The emerald ash borer (Agrilus planipennis) is an invasive wood-boring beetle that has killed millions of ash trees since its accidental introduction to North America. All North American ash species (Fraxinus spp.) that emerald ash borer has encountered so far are susceptible, while an Asian species, Manchurian ash (F. mandshurica), which shares an evolutionary history with emerald ash borer, is resistant. Phylogenetic evidence places North American black ash (F. nigra) and Manchurian ash in the same clade and section, yet black ash is highly susceptible to the emerald ash borer. This contrast provides an opportunity to compare the genetic traits of the two species and identify those with a potential role in defense/resistance. We used Difference Gel Electrophoresis (DIGE) to compare the phloem proteomes of resistant Manchurian to susceptible black, green, and white ash. Differentially expressed proteins associated with the resistant Manchurian ash when compared to the susceptible ash species were identified using nano-LC-MS/MS and putative identities assigned. Proteomic differences were strongly associated with the phylogenetic relationships among the four species. Proteins identified in Manchurian ash potentially associated with its resistance to emerald ash borer include a PR-10 protein, an aspartic protease, a phenylcoumaran benzylic ether reductase (PCBER), and a thylakoid-bound ascorbate peroxidase. Discovery of resistance-related proteins in Asian species will inform approaches in which resistance genes can be introgressed into North American ash species. The generation of resistant North American ash genotypes can be used in forest ecosystem restoration and urban plantings following the wake of the emerald ash borer invasion
Global and national Burden of diseases and injuries among children and adolescents between 1990 and 2013
Importance The literature focuses on mortality among children younger than 5 years. Comparable information on nonfatal health outcomes among these children and the fatal and nonfatal burden of diseases and injuries among older children and adolescents is scarce.
Objective To determine levels and trends in the fatal and nonfatal burden of diseases and injuries among younger children (aged <5 years), older children (aged 5-9 years), and adolescents (aged 10-19 years) between 1990 and 2013 in 188 countries from the Global Burden of Disease (GBD) 2013 study.
Evidence Review Data from vital registration, verbal autopsy studies, maternal and child death surveillance, and other sources covering 14 244 site-years (ie, years of cause of death data by geography) from 1980 through 2013 were used to estimate cause-specific mortality. Data from 35 620 epidemiological sources were used to estimate the prevalence of the diseases and sequelae in the GBD 2013 study. Cause-specific mortality for most causes was estimated using the Cause of Death Ensemble Model strategy. For some infectious diseases (eg, HIV infection/AIDS, measles, hepatitis B) where the disease process is complex or the cause of death data were insufficient or unavailable, we used natural history models. For most nonfatal health outcomes, DisMod-MR 2.0, a Bayesian metaregression tool, was used to meta-analyze the epidemiological data to generate prevalence estimates.
Findings Of the 7.7 (95% uncertainty interval [UI], 7.4-8.1) million deaths among children and adolescents globally in 2013, 6.28 million occurred among younger children, 0.48 million among older children, and 0.97 million among adolescents. In 2013, the leading causes of death were lower respiratory tract infections among younger children (905 059 deaths; 95% UI, 810 304-998 125), diarrheal diseases among older children (38 325 deaths; 95% UI, 30 365-47 678), and road injuries among adolescents (115 186 deaths; 95% UI, 105 185-124 870). Iron deficiency anemia was the leading cause of years lived with disability among children and adolescents, affecting 619 (95% UI, 618-621) million in 2013. Large between-country variations exist in mortality from leading causes among children and adolescents. Countries with rapid declines in all-cause mortality between 1990 and 2013 also experienced large declines in most leading causes of death, whereas countries with the slowest declines had stagnant or increasing trends in the leading causes of death. In 2013, Nigeria had a 12% global share of deaths from lower respiratory tract infections and a 38% global share of deaths from malaria. India had 33% of the world’s deaths from neonatal encephalopathy. Half of the world’s diarrheal deaths among children and adolescents occurred in just 5 countries: India, Democratic Republic of the Congo, Pakistan, Nigeria, and Ethiopia.
Conclusions and Relevance Understanding the levels and trends of the leading causes of death and disability among children and adolescents is critical to guide investment and inform policies. Monitoring these trends over time is also key to understanding where interventions are having an impact. Proven interventions exist to prevent or treat the leading causes of unnecessary death and disability among children and adolescents. The findings presented here show that these are underused and give guidance to policy makers in countries where more attention is needed
Global, regional, and national incidence, prevalence, and years lived with disability for 328 diseases and injuries for 195 countries, 1990–2016: a systematic analysis for the Global Burden of Disease Study 2016
As mortality rates decline, life expectancy increases, and populations age, non-fatal outcomes of diseases and injuries are becoming a larger component of the global burden of disease. The Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016) provides a comprehensive assessment of prevalence, incidence, and years lived with disability (YLDs) for 328 causes in 195 countries and territories from 1990 to 2016
