EFFECTIVENESS OF INTEGRATED CARBON CAPTURE TECHNOLOGY IN WASTE TO ENERGY PLANTS AND IMPLEMENTATION PROSPECTS

The population in ASEAN is projected to increase to 722 million by 2030. This massive population increase had an impact not only on population quantity but also on the environment. This is reflected in the increasing number of pollution results such as waste products and carbon pollution. Waste to Energy Plants has been successful in converting waste to electrical energy by incineration, but there are still carbon emissions that has to be dealt with and on the other hand carbon pollution has been a major problem for ASEAN this past 10 years, with the data from Global Carbon Atlas showing 1671.7 MtCO2 are emitted from the combined 10 countries in 2019. The industry categories of petroleum refineries, chemicals and others are responsible for contributing the most greenhouse gases. Analysis from the International Energy Agency shows comparison between few of the most promising solutions for carbon emission, one of them being Carbon Capture Storage (CCS). This technology captures CO2 that has been emitted to the atmosphere. Indonesia, the biggest country in ASEAN is also the region’s most contributing country in terms of carbon emission where the CCS technology should be developed more. In this paper, the author uses a descriptive qualitative method and data reference from previous research. The results indicate that the usage of CCS is very effective to reduce the CO2 emissions emitted from Waste-to- Energy Plants with 95% accuracy. This, in effect, will ensure effective expert knowledge communication to the general public and foster social acceptance of this technology.

Catch and Length Models in the Stock Synthesis Framework: Expanded Application to Data-Moderate Stocks

Many fisheries in the world are data-moderate, with data types (e.g., total removals, abundance indices, and biological composition data) of varied quality (e.g., limited time series or representative samples) or available data. Integrated stock assessments are useful tools for data-moderate fisheries as they can include all available information, can be updated due to the availability of more information over time, and can directly test the inclusion and exclusion of specific data types. This study uses the simulation testing and systematic data reduction from the US West Coast benchmark assessments to examine the performance of Stock Synthesis with catch and length (SS-CL) compositions only. The simulation testing of various life histories, recruitment variabilities, and data availability scenarios found that the correctly specified SS-CL can estimate unbiased key population quantities such as stock status with as little as 1 year of length data although 5 years or more may be more reliable. The error in key population quantities is decreased with an increase in years and the sample size of length data. The removal of the length compositions from benchmark assessments often caused large model deviations in the outputs compared to the removal of other data sources, indicating the importance of length data in integrated models. Models with catch and length data, excluding abundance indices and age composition, generally provided informative estimates of the stock status relative to the reference model, with most data scenarios falling within the CIs of the reference model. The results of simulation analysis and systematic data reduction indicated that SS-CL is potentially viable for data-moderate assessments in the USA, thus reducing precautionary buffers on catch limits for many stocks previously assessed in a lower tier using catch-only models. SS-CL could also be applied to many stocks around the world, maximizing the use of data available via the well tested, multifeature benefits of SS.

Research on the driving effect of production electricity consumption changes in the Yangtze River Economic Zone - Based on regional and industrial perspectives

In this study, the LMDI method is used to decompose the production power consumption changes of the Yangtze River Economic Zone into an advanced technology effect, structural effect, income effect, and population effect. The regional and industry differences in the driving effect of electricity consumption change are also investigated. From the perspective of time differences, the progress of power-saving technology is the main factor restraining the growth of electricity consumption; whereas, economic growth, industry structure adjustment, and population size adjustment promote the growth of electricity consumption; and the other three influencing factors, in turn, decrease. From the perspective of regional differences, regional electricity consumption varies significantly, and various regions have great room for improvement in industry structure. Regional population affects electricity consumption from two aspects: absolute population quantity change and population mobility. From the perspective of industry differences, electricity consumption varies significantly among industries and is mainly reflected in the effect of technological progress and structural effects. As a result, control measures on electricity consumption in the Yangtze River Economic Zone should focus on the promotion of power-saving technology and industry structure adjustment.

Soil water carrying capacity for vegetation

AbstractNonnative plantations can effectively conserve soil and water and improve the ecology and environment, but soil desiccation can occur and may become severe in forest and grass lands in water‐limited regions, leading to soil degradation, vegetation decline, and crop failure. Therefore, it is necessary to regulate the changing relationship between plant growth and soil water. However, there is no universally accepted theory to provide guidance in the sustainable use of soil water resources, management of forests, and production of crops in such regions. The regulation of the relationship between plant growth and soil water in water‐limited regions can be expressed by the soil water resources use limit by plant (SWRULP) and soil water carrying capacity for vegetation (SWCCV) indexes. The SWCCV is the population in a plant population or density of indicator plants in a plant community when the soil water supply is equal to soil water consumption in the root zone at a given time, and changes with plant community type, location, and time. For example, the SWRULP in caragana shrubland is 222.8 and the SWCCV is 71 bushes per 100 m2 in the semiarid region. The degree of coverage, productivity, and benefits of a plant community when the population quantity of an indicator plant equals the SWCCV provides the theoretical basis for ensuring the sustainable use of soil water resources and sustainable development of forest land.

Transcriptional and Epigenetic Landscape of Cardiac Pacemaker Cells: Insights Into Cellular Specialization in the Sinoatrial Node.

Cardiac pacemaker cells differentiate and functionally specialize early in embryonic development through activation of critical gene regulatory networks. In general, cellular specification and differentiation require that combinations of cell type-specific transcriptional regulators activate expression of key effector genes by binding to DNA regulatory elements including enhancers and promoters. However, because genomic DNA is tightly packaged by histones that must be covalently modified in order to render DNA regulatory elements and promoters accessible for transcription, the process of development and differentiation is intimately connected to the epigenetic regulation of chromatin accessibility. Although the difficulty of obtaining sufficient quantities of pure populations of pacemaker cells has limited progress in this field, the advent of low-input genomic technologies has the potential to catalyze a rapid growth of knowledge in this important area. The goal of this review is to outline the key transcriptional networks that control pacemaker cell development, with particular attention to our emerging understanding of how chromatin accessibility is modified and regulated during pacemaker cell differentiation. In addition, we will discuss the relevance of these findings to adult sinus node function, sinus node diseases, and origins of genetic variation in heart rhythm. Lastly, we will outline the current challenges facing this field and promising directions for future investigation.

Adjusted logistic propensity weighting methods for population inference using nonprobability volunteer-based epidemiologic cohorts.

Many epidemiologic studies forgo probability sampling and turn to nonprobability volunteer-based samples because of cost, response burden, and invasiveness of biological samples. However, finite population (FP) inference is difficult to make from the nonprobability sample due to the lack of population representativeness. Aiming for making inferences at the population level using nonprobability samples, various inverse propensity score weighting methods have been studied with the propensity defined by the participation rate of population units in the nonprobability sample. In this article, we propose an adjusted logistic propensity weighting (ALP) method to estimate the participation rates for nonprobability sample units. The proposed ALP method is easy to implement by ready-to-use software while producing approximately unbiased estimators for population quantities regardless of the nonprobability sample rate. The efficiency of the ALP estimator can be further improved by scaling the survey sample weights in propensity estimation. Taylor linearization variance estimators are proposed for ALP estimators of FP means that account for all sources of variability. The proposed ALP methods are evaluated numerically via simulation studies and empirically using the naïve unweighted National Health and Nutrition Examination Survey III sample, while taking the 1997 National Health Interview Survey as the reference, to estimate the 15-year mortality rates.

Soil bacterial community in potato tuberosphere following repeated applications of a common scab suppressive antagonist

Disease suppressive soils are important for managing soil-borne diseases that cannot be controlled with chemicals. One such disease is the potato common scab caused by Streptomyces species. Suppressiveness against common scab can develop spontaneously in fields where potato is grown for years without interruption, and this has been attributed to non-pathogenic Streptomyces strains. Streptomyces spp. have been used as inoculants in biological control, but their long-term effects have gained less attention. In our previous studies, a non-pathogenic Streptomyces strain (Str272) isolated from a potato common scab lesion suppressed common scab in field trials lasting over 5 years. In this study, bacterial communities in the tuberosphere i.e. in the soil adjacent to potato tubers, were analysed by next generation sequencing (NGS). The aim was to compare bacterial communities in untreated control plots to those in which seed tubers were treated with Str272 in one or several growing seasons. Str272 applications increased soil bacterial diversity and affected the bacterial composition in the potato tuberosphere. The most pronounced differences were observed between the untreated control and the treatments in which the antagonist had been applied in three or four consecutive years. The differences remained similar until the following growing season. Bacterial composition after repeated antagonist applications was associated with lower common scab severity. The antagonist applications had no or only slight effect on the number or abundance of OTUs belonging to Actinobacteria or Streptomyces, and no differences in quantities of pathogenic Streptomyces populations were detected by qPCR. This indicates that suppression of common scab by Str272 may not be based on direct effect on the common scab pathogens but is more likely to be associated with the alterations of the soil bacterial community. The most abundant bacteria phyla in the potato tuberosphere were Actinobacteria, Proteobacteria and Acidobacteria. However, the OTUs responding greatest to the antagonist treatments belonged to Bacterioidetes and Gemmatimonadetes. Results indicate that repeated applications of Str272 can change the bacterial community in the potato tuberosphere and lead to development of soil that is suppressive against potato common scab for several growing seasons after the last application.

Изменчивость полового диморфизма основных антропометрических размеров тела новорожденных в связи со степенью урбанизации

The study embraces big volume of literary data – over 120 samples of newborns of each sex from former USSR of 1960s, including main anthropometric dimensions (height, weight, chest and head girths). The quantitative estimation of the level of sexual dimorphism (SeD) is accomplished using Kullback divergence – analogue of the Mahalanobis distance. The parameter of quantity of population of the residence place, associated with the income level, nutrition status and frequency of socially significant diseases, is used as the marker of the degree of urbanization. Results. The level of Sed of newborn infants has modest fluctuations and for most somatic traits has average meaning about 0,3 standard deviations, independently of the degree of urbanization of the residence place of territorial/ethnic groups. Still the living standards in big millionaire cities are favorable to the progress (improvement) of physical status of male infants – increase of head girth in Moscow megalopolis, increase of height/weight dimensions of both Russian and aboriginal newborns in Tashkent – which promotes some increase of Sed of somatic traits as well. Conclusion. Somatic dimensions of newborns are the classic object of stabilizing selection, hence have very moderate variability. In this context, quantitative meaning of SeD of body dimensions is also relatively stable.

Determination of The Prevalence and Population Development of Tomato Leafminer [Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae)] in Tomato (Lycopersicon esculentum Mill.) Planting Areas of Sanliurfa Province

This study was carried out to determine the extensity, development of population and the state of damage of tomato leaf miner (Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae)) in total eight tomato fields located in the villages of Goktepe of Central Sanliurfa, Meteler of Birecik, Kepirce of Bozova, Yalcinkaya of Ceylanpinar, Ovacik of Hilvan, Kucuk Yucelen of Siverek, Aligor of Suruc and Ciftciler of Viransehir in 2011. To determine the extensity of tomato leaf miner each of the 5 districts in the village tomato field was checked by observation whether adult or larvae found in fields T. absoluta. The result showed that tomato leaf miner was common in all the districts. The highest density of tomato leaf miner adult population quantities were 630, 800, 400, 965, 211, 600, 215 and 96 pcs/week in Goktepe of Central Sanliurfa, Meteler of Birecik, Kepirce of Bozova, Yalcinkaya of Ceylanpinar, Ovacik of Hilvan, Kucuk Yucelen of Siverek, Aligor of Suruc and Ciftciler of Viransehir, respectively. Tomato leaf miner harmed the fruits, particularly total in 1st and 2nd harvest of tomato (the end of August- the beginning of September) , if precautions were not taken. Moreover, it was recorded that if the adult population was quite dense in the fields study conducted, there aren’t any undamaged leaves and fruits from T. absoluta.

Synchronization of Policies and Performance Achievements: Which Should Come First?

Synchronization of development policies in the field of population and family planning is an issue in the central, provincial and district/city governments as stipulated in Law No. 23/2014. Article 8 paragraph 2 of the Law states that population quantity control is carried out through synchronization of population policies at the national level and regions. Therefore, work programs in the population control at the district/city level are highly varied according to the problem. Family planning promotion, counseling and advocacy are programs in all districts/cities targeting the couples of childbearing age and adolescents. The study of program plan and regulatory documents for the 2019-2024 fiscal year became the basis for focused discussions with various levels of government, namely the central, provincial, regency/city and sub-district level. Targets, strategies, programs and activities which include types, objectives, objectives, coverage and achievements are components to be examined for content, consistency and synchronization. Meanwhile, policy synchronization can be seen from the formulation of work programs. The results of the study show that directly, the provincial work program is linear with the national agenda

Increase in quantity of population, development of industry and agriculture has created a systemic growth of demand on water. Despite the fact that Georgia is rich in natural water resources having high quality drinking properties, in many regions and, especially, in semi-arid and humid zones, the problem of supplying the population with clean drinking water is quite acute. The article is about the issue of utilizing the waters formed in the River Cheremiskhevi bed for prospectively supplying with water the villages (Village Velistsikhe, Village Zegaani, Village Mukuzaani) in Gurjaani municipality situated on the North-East slope of Tsiv-Gombori Ridge. With this purpose, in 2013-2020, the chemical and sanitarymicrobiological characteristics of the filtrate waters in alluvial-proluvial sediments and surface (river) runoff of the River Cheremiskhevi were studied in field and stationary conditions.

Weighted Dirichlet Process Mixture Models to Accommodate Complex Sample Designs for Linear and Quantile Regression.

Standard randomization-based inference conditions on the data in the population and makes inference with respect to the repeating sampling properties of the sampling indicators. In some settings these estimators can be quite unstable; Bayesian model-based approaches focus on the posterior predictive distribution of population quantities, potentially providing a better balance between bias correction and efficiency. Previous work in this area has focused on estimation of means and linear and generalized linear regression parameters; these methods do not allow for a general estimation of distributional functions such as quantile or quantile regression parameters. Here we adapt an extended Dirichlet Process Mixture model that allows the DP prior to be a mixture of DP random basis measures that are a function of covariates. These models allow many mixture components when necessary to accommodate the sample design, but can shrink to few components for more efficient estimation when the data allow. We provide an application to the estimation of relationships between serum dioxin levels and age in the US population, either at the mean level (via linear regression) or across the dioxin distribution (via quantile regression) using the National Health and Nutrition Examination Survey.

Microbiological quality of tempeh with different wraps: banana leaf versus plastic.

Tempeh is a traditional Indonesian fermented food widely consumed and became staple food in someIndonesian diet. Commercially, tempeh is available in banana leaf or plastic wraps. The wraps arenot only important for fermentation and giving final form of tempeh, but also potential source of food microbiome. This study aimed to investigate the effect of different packaging materials on the lactic acid bacteria (LAB) quantity and community composition of tempeh from three manufacturers with different production environments. Each tempeh wrapped with banana leaf or plastic during the fermentation process and then LAB from every tempeh sample were quantified using qPCR and plate count method. Terminal Restriction Fragment Length Polymorphism analysis was carried out to assign bacterial community composition from these samples. The LAB population quantity of fresh tempeh from three manufacturers were essentially similar around 10 log CFU/g. However, there is a difference in the proportion of cultured and uncultured bacteria. Principal Coordinate Analyses based on Bray-Curtis similarity matrices showed an apparent clustering pattern for tempeh samples according to tempeh manufacturers. Meanwhile, packaging materials did not significantly influence changesin bacterial community composition. The result of this work could be used for determination, authentication, and improvement of tempeh quality.

Forecasting Model and Related Index of Pig Population in China

The systematic and reasonable prediction of pig population is the basis for balance and symmetry between the supply and demand of hogs, which is of great significance to the pig industry. Based on the population prediction model and according to the principle of pig months transfer, this paper referred to the modeling principle and method of the discrete population quantity prediction model and established a related index model that can reflect the pig population development process. The forecasting model we have established includes the following models: (a) a recursive model of pig population, (b) an estimation model of new kept piglets and breeding sows in each month, (c) an estimation model of the initial state of the quantity of the pig population, and (d) a related index model to calculate pig population. On this basis, an example calculation was made to predict the monthly pig population and the quantitative distribution of pigs with different age groups in China from January 2016 to March 2018 in the future. The results showed that the forecasting model of pork supply based on the prediction of pig population is an effective perspective to study the future quantity of pork supply. In the fitting stage, the relative error of the number of slaughtered fattened hogs was 0.0332 and 0.0368. In the prediction stage, the relative error of the quantity of pork supply was 0.0618 and 0.0578.

Nonlinear state-dependent pulse control for an SIRS epidemic model with varying size and its application to the transmission of brucellosis

As the disease spreads, it will inevitably cause important damage to the life and health of the population, resulting in changes in the population quantity. In addition, in some economically underdeveloped areas, limited medical resources will also have an important impact on the prevention and control of diseases. Based on these, a susceptible-infected-recovered-susceptible (SIRS) epidemic model is established, where state-dependent pulse control strategy, varying total population and limited medical resources are introduced. By using the qualitative theory of ordinary differential equation, differential inequality techniques, Poincaré map, and other methods, some sufficient conditions of the existence and orbital asymptotical stability of positive order-1 or order-2 periodic solution are obtained in various situations. Theoretical results imply that the proportion of infected class can be controlled at a desired low level for a long time and disease will not break out among population. Finally, based on realistic parameters of brucellosis in ruminants, numerical simulations have been performed to expalin/extend our analytical results and the feasibility of the state-dependent feedback control strategy.

Stellar initial mass function over a range of redshifts

The stellar Initial Mass Function (IMF) seems to be close to universal in the local star‐forming regions. However, this quantity of a newborn stellar population responds differently at gas metallicities Z ∼ Z⊙ than Z = 0. A view on the cosmic star formation history suggests that the cooling agents in the gas vary both in their types and molecular abundances. For instance, in the primordial gas environment, the gas temperature can be higher by a factor of 30 as compared to the present day. Stellar radiation feedback and cosmic microwave background (CMB) radiation may even contribute toward increasing the floor temperature of the star‐forming gas which subsequently can leave profound impacts on the IMF. We present the contribution of the radiation sources toward the thermodynamical evolution of the Jeans unstable gas cloud which experiences fragmentation and mass accretion. We find evidence which suggests that the latter becomes the dominant process for star formation efficiencies (SFE) above 5–7%, thus increasing the average mass of the stars. We focus on the isolated and binary stellar configurations emerging during the gas collapse. The binary fraction on average remains 0.476 and contributes significantly toward the total SFE of 15%.

Evaluation of the State of Ecological Sphere Vital Activity in the Medium-Size Cities

The analysis of the state of ecological sphere development in the medium-size cities of Ukraine certifies the presence of negative tendencies there, exactly, the decrease of population quantity, the growth of numbers of movable sources and the level of population morbidity. There has been suggested a scale to make qualitative and quantitative evaluation of the changes of ecological sphere state according to which indices ascertain the correspondence with their states: 1,0 – 0,75 as high, 0,749 – 0,50 as medium, 0,499 – 0,25 as less than medium, 0,249 –0, as low. It is revealed that high level of ecological development refers to Ivano-Frankivsk (0,777), which is the leader according to the level of planting greenery, the lowest accumulation of waste materials of the 1st – 3d level of danger, the lowest emission of pollutants into atmosphere from stationary and movable sources. Melitopol has medium level (0,57) and is the leader as to the indices of drinking water consumption and is characterized by good indices concerning the waste treatment, considerable expenses spent on nature-protecting activity and low amount of pollutant emission into atmosphere. The cities of Lutsk and Rivne are characterized by lower than medium level of the development of ecological sphere vital activity (0,482; 0,384 in the year 2017 correspondingly), because of a great amount of pollutants emission into atmosphere, low level of planting greenery. The city of Rivne, besides, has the highest indices as to the assumption of waste materials and the least expenses on nature-protecting measures. It is ascertained that the influence of destimulators and stimulators on the level of development of medium-size cities ecological sphere is described by dependencies which look like straight lines at the coefficients of determination R2 from 0,381 to 0,721.
