Developing a robust indicator to evaluate circular economy through reuse strategy: A case study of using water treatment sludge as a coagulant for dewatering of iron ore tailings slurry

Due to the lack of tools, which are simple enough to assess the reuse strategy in the concept of circular economy (CE), in the present paper, reuse efficiency index (REI) was introduced as a new indicator, inspired by previously developed indexes, namely circular economy index (CEI) and value-based resource efficiency (VRE). The REI, as a measure of economic efficiency of reuse strategy, is the ratio of the net value obtained from the reuse of end of life (EOL) product instead of using a new product over the value of materials and energy inputs required to reproduce the EOL product. To calculate REI for any specific EOL product, information regarding mass, physicochemical properties and operational data on the consumption of energy, which are mainly available in the financial archives of companies, is crucial and the market price of EOL product must also be predicted. In another part of the study, the reuse of ferric chloride-based water treatment sludge (FCS) as a coagulant, instead of using high cost polymeric coagulant, for iron ore tailings slurry dewatering was evaluated through REI. The results showed that depending on the market prices of energy and materials as well as the iron (FeCl3) content in the FCS, the REI could vary between 0.51 and 1.04, corresponding to 51–104% added value. Overall, REI is based on accessible information and its simplicity and comprehensibility makes it applicable for managers and policymakers to invest and create technologies for reaching closed-loop cycles in the concept of CE through reuse action.

Effects of genetic and environmental trends from 1970 to 2020 on farm efficiency estimated with a whole farm modeling system

The objectives of this study were to evaluate associations of genetic, cow management and nutrition, inbreeding, and crop yields from 1970 to 2020 with measures of production and economic efficiency according to a whole farm model, and to evaluate effects of genetic change in individual traits on economic efficiency in comparison to expectations from economic selection indexes. Genetic and phenotypic performance metrics for Holsteins from 1970 and 2020 were retrieved and input into the Integrated Farm System Model (IFSM) for a 7000 cow TX herd and a 50 cow PA grazing herd. Crop yields estimates from 1970 and 2020 were retrieved and farm hectarage was altered so that forage and energy concentrate requirements were met through farm production; likewise, scenarios evaluating effects of atmospheric CO2 fertilization (CO2F) on crop yield were evaluated by altering farm hectarage. For single traits that could be dynamically modeled by IFSM, performance shifts and resulting change in product prices or management expenses were added to 1970 base models. Economic efficiency was evaluated as the per cow return to management and unpaid factors as compared with 1970 base models. As averaged across state scenarios, gains in economic efficiency were +$945 and -$76 for additive genetic and inbreeding effects, respectively, for a total gain from genetic change of +$869. Genetic gain in fat yield (+$549) and protein yield (+$524) were responsible for most of the genetic gain, whereas milk yield (-$128) and increased cow BW (-$129) depressed economic efficiency. Genetic change in productive life had a smaller effect (+$44) than predicted unless heifers were purchased and at double the default value. Gains due to cow management and nutrition increased efficiency by +$666 and crop yield increased efficiency by +$711, of which +$371 was attributed to CO2F across scenarios. Whole farm dry matter efficiencies derived as the ratio of fat and protein corrected milk yield to dry matter intake increased from 0.82 (PA) and 0.97 (TX) in 1970 to 1.20 in 2020 and could be higher if farms reduce the size of their replacement herd by producing beef calves. The landmass required in 2020 was 63% and 78% of the 1970 requirement for TX and PA, respectively. Changes in cow genetic merit, management and nutrition, and crop yields have all increased the economic and environmental sustainability of milk production, and systems such as IFSM could be a useful tool to help inform economic selection indices.

Influences of Bacillus pumilus SA388 as an environmentally friendly antibiotic alternative on growth performance, blood biochemistry, immunology, cecal microbiota, and meat quality in broiler chickens

The widespread use of antibiotics causes the development of antibiotic-resistant bacterial strains, which have a severe impact on poultry productivity and human health. As a result, research is continuing to develop safe natural antibiotic alternatives. In the current study, Bacillus pumilus SA388 was isolated from the chicken feces and confirmed to be a probiotic. The selected strain was tested for its antimutagenic and antioxidant capabilities before being employed as a probiotic food supplement and antibiotic alternative. The effect of B. pumilus SA388 impact on broiler chickens' growth performance, gut microbiome, blood biochemical markers, immunological response, and meat quality was also studied. B. pumilus SA388 showed significant bactericidal activity against Streptococcus pyogenes, Listeria monocytogenes, Staphylococcus aureus, Escherichia coli, Salmonella typhi, and Klebsiella pneumonia. A total of 200 chickens were used in the present study, divided equally among four experimental groups (ten birds per group with 5 replicates): group 1 (control, G1) received a basal diet without B. pumilus SA388, group 2 (G2) received a basal diet supplemented with 0.4 mg/kg of B. pumilus SA388, group 3 (G3) received a basal diet supplemented with 0.8 mg/kg of B. pumilus SA388, and group 4 (G4) received a basal diet supplemented with 1.6 mg/kg of B. pumilus SA388. Over 35 d, the B. pumilus SA388-supplemented groups outperformed the G1 in terms of body weight gain, performance index, and feed conversion ratio, with a preference for the G4 treatment. The levels of alanine aminotransferase (ALT), aspartate transaminase (AST), low-density lipoprotein (LDL), and total cholesterol decreased significantly (P < 0.05) with increasing B. pumilus SA388 dosages compared to the control G1 group. Dietary supplementation of B. pumilus SA388 at 1.6 mg/kg (G4) significantly (P < 0.05) resulted in improved lipid profile, immunological response, thyroid function, and gut microbiota compared to the control group (G1). Compared to the broilers in the control treatment (G1), the addition of B. pumilus SA388 to broilers in G4 significantly (P < 0.05) enhanced juiciness, tenderness, aroma, and taste. Adding B. pumilus SA388 to chicken feed at different doses significantly (P < 0.05) decreased average feed intake while increasing economic and relative efficiency measures. In conclusion, B. pumilus SA388 has been proven to be an effective antibiotic and nutritional supplement.

Measurement and synergistic evolution analysis of economic resilience and green economic efficiency: Evidence from five major urban agglomerations, China

It has become a significant issue for urban economies to maintain efficient and green development while ensuring security and stability. This study evaluated economic resilience (ER) and green economic efficiency (GEE) in China's five urban agglomerations using the combined weight model and the meta-frontier global super-efficiency SBM model with undesired outputs. Analyzed synergistic degrees between ER and GEE and regional differences by the modified coupled coordination model and Dagum's Gini coefficient. Results indicated that ER overall showed an increase from 2003 to 2021. GEE exhibited a slanting 'W' shaped trend but remained generally upward. In addition, the synergistic degree between ER and GEE increased, indicating beneficial interactions and a trend of synergistic evolution moving towards advancement. Spatial differences in synergistic degree were mainly due to hypervariable density, with inter-regional variations as a secondary factor. The Pearl River Delta (PRD) showed the highest intra-regional variation in synergistic degree and the Chengdu-Chongqing region (CC) the least. The synergistic gap between CC and PRD was the largest, while the gap between CC and the middle reaches of the Yangtze River (MYR) was the smallest. Understanding ER and GEE's spatiotemporal evolution is expected to induce sustainable economic development in urban agglomerations further.

Measured performance of energy efficiency measures for zero-energy retrofitting in residential buildings

Retrofitting existing buildings to Nearly Zero Energy Buildings (NZEBs) can significantly reduce their energy consumption and environmental impact. However, practitioners and policymakers still face the challenge of providing effective and economic energy efficiency measures (EEMs) to interested parties, due to the limited data on the actual performance of available EEMs. This study addresses the data deficiency by analyzing the actual energy and cost performance of a retrofitted single-family house towards a NZEB. Itemized electricity consumptions, including power consumption of heat pump, water pump, fan, and other accessories, as well as whole building usage, are measured before and after the renovation. New metrics are devised for effectiveness assessment – estimating energy savings upon degree day, cost and change in envelope thermal resistance R-value. The contribution of each EEM to the achieved energy savings is identified and compared. For energy consumption of air-water source heat pump, exterior wall retrofit yields the greatest savings: 1.02 kWh/dd (22.2 %) in winter and 0.64 kWh/dd (33.1 %) in summer, followed by roof retrofit. When the savings are analyzed in terms of per unit increment of R-value, windows/doors retrofit demonstrates the highest priority: 1.66 kWh/dd per unit increment of R-value in winter and 0.62 kWh/dd per unit increment of R-value in summer. Considering costs and energy saving contribution together, the optimal retrofit measure is roof retrofit. This study also contributes to the topic by adding new data to the field and extending retrofit practices to locations outside of North America and Europe.

Economic and Productive Comparison of Rutin and Rutin-Loaded Chitosan Alginate Nanoparticles Against Lead-Induced Oxidative Stress in Cobb and Arbor Broiler Breeds

Rutin, a natural bioflavonoid compound, is one of the best-known antioxidants. This study aimed to investigate the protective effect of rutin-loaded chitosan alginate nanoparticles (RCA NPs) against lead (Pb)-induced oxidative stress in two different broiler breeds. A total number of 240 chicks from Cobb (CB) and Arbor Acres (AR) breeds were randomly allocated into 4 groups/breed. The 1st group received standard basal diet (SD) and drinking water (DW) while the 2nd group received SD and Pb-incorporated DW (350 mg/L). The 3rd group treated with both rutin-supplemented SD (50 mg/kg feed), and DW contain Pb (350 mg/L). Finally, the 4th group administered RCA NPs-supplemented SD (50 mg/kg feed) and Pb-incorporated DW (350 mg/L). On the 40th day of experiment, broilers weighed, and blood samples collected for biochemical and hematological analysis then slaughtered. Economic efficiency, growth performance, and oxidative stress biomarkers were evaluated. Gene expression level of growth-associated genes as insulin-like growth factor-I (IGF-1) and histopathological changes were assessed in liver and intestinal tissue of both breeds. Our results revealed that Pb-treated birds exhibited the lowest average body weight gain (BWG) and economic efficiency measures in both breeds while RCA NPs-treated groups revealed enhanced growth and economic performance. Furthermore, diet supplementation with RCA NPs considerably enhanced the antioxidant enzymes activity and expression of growth-associated genes than groups treated with rutin alone specifically in AR breed. In conclusion, RCA NPs supplementation could be a promising nanoformulation in poultry production through enhancing the antioxidant capacity and bioavailability of rutin.Graphical

Enhancing green total factor productivity through manufacturing output servitization: A case study in China

In the context of the growing environmental pollution and resource depletion caused by traditional manufacturing industries, the need for sustainable and eco-friendly practices has become a critical issue for the upgrading and transformation of the manufacturing industry worldwide. Based on data from listed manufacturing companies in China, which is the world's largest manufacturing country and exhibits significant diversity regarding the ownership, scale and level of enterprises, the impact of manufacturing output servitization on green total factor productivity (GTFP), which is a measurement of economic efficiency that takes into account environmental impacts, is analyzed in this article. The results show that manufacturing output servitization can improve the GTFP of enterprises, and this can be achieved through mechanisms such as increased profitability and innovation capabilities. The positive effect on the GTFP of enterprises in less developed regions is greater than that in developed regions and is more significant for private and foreign-funded enterprises than for state-owned enterprises. The companies that adhere to the Global Reporting Initiative framework for environmental, social and governance reporting experience a more significant positive impact on GTFP as a result of their manufacturing output servitization efforts. This research offers valuable insights into the potential of servitization as a strategy for enhancing GTFP and provides actionable guidance for policy-makers and industry stakeholders seeking to align manufacturing practices with sustainability goals.

EFFECTS OF DIETARY NUCLEOTIDES SUPPLEMENTATION ON THE PERFOR-MANCE OF BROILER CHICKS

This study examined the effects of nucleotide supplementation on broiler chick growth performance, immunological response, carcass traits, meat quality, serum biochemical parameters, total antioxidant capacity, intestinal morphology, mortality rate, and economic efficiency measures of broiler chicks. A total of 180 one-day-old chicks (Ross 308) were distributed into 6 groups, each of which consisted of 30 chicks, and each group was divided into 3 replicates so that each replicate contained 10 chicks fed on six experimental diets as follows: basal diet without oil or nucleotide (T1), basal diet with 1% soybean oil and without nucleotide(T2), 50 grams nucleotide per 100-kilogram diet with different fat sources (no oil(T3), 1% soybean oil(T4), 1% linseed oil(T5) &amp;1% fish oil(T6) respectively during the experimental period (5 weeks). Growth performance parameters were detected per stage period. Four chicks from each replicate were used at the termination of the experiment for analysis of the above mentioned measurements. Results revealed that supplementation of nucleotide in diets of broiler chicks improved feed conversion ratio, carcass traits, intestinal morphology, serum biochemical parameters, immunological response, bursa of Fabricius weight, and the best ratios were observed in groups fed nucleotide in combination with fish and linseed oil. Also, there was an increased economic efficiency in the SBO fed group(T2) then group fed nucleotides in mix with linseed oil (T5) and control (T1). In comparison to the control groups (T1 &amp; T2), groups fed nucleotides and PUFA oil sources had significantly lower n-6: n-3 ratio in breast muscle, and mortality rate.

Merenje produktivnosti, proizvodna funkcija i Divisia indeksni brojevi

The objective of this study is the theoretical and methodological analysis of the total productivity index, as a measure of economic efficiency, assuming the existence of various inputs and various outputs. The defined index is a measure of the overall change in productivity. The obtained chain two-factor indices are rationalized Divisia indices. The study actualizes the issues of economic efficiency, measurements of productivity and total productivity, promotes relevant literature in this field, offering a simple methodology with numerous applications at the same time. The presented concept is based on index numbers of total productivity of all factors. Using this approach, net output is compared to a weighted average of all factor inputs. Therefore, a significant part of the study is particularly the input weighting methodology, since it enables the appropriate connection of inputs and outputs, combining their different units of measure at the same time. The results obtained by applying the presented methodology in this paper provide the basis for numerous empirical analyses of the level and dynamics of changes in the economies' efficiency. Due to its simplicity, this approach has several advantages over other similar approaches.

Assessing the role of economic globalization on energy efficiency: Evidence from a global perspective

There has been concern that economic globalization will increase energy consumption and reduce energy efficiency. A slew of studies investigating this assertion have used trade, foreign investment, or both as indicators of economic globalization, with mixed findings. A number of concerns challenge the empirical literature including measurement issues, infrequent temporal variations in the data, business cycle effects and heterogeneity bias, which affect the causal ability of economic globalization. This study used global data of 141 countries to assess the effects of economic globalization on energy efficiency. Our identification strategies involved using more refined measures of economic globalization and energy efficiency, addressing infrequent temporal variations as well as business cycle effects and concerns of heterogeneity bias. Largely, economic globalization positively drives energy efficiency, but this effect suffers from upward bias without controls. We note that infrequent temporal variations in the data and business cycle effects and heterogeneity bias drive the result. Concerning the latter, the result has shown that economic globalization improves energy efficiency only in upper-middle and lower-middle income countries and not in high and lower-income countries. Our results raise serious caution about the causal abilities of existing studies. And we discuss the policy implications.

ECONOMIC EFFICIENCY OF SPRING TRITICALE PRODUCTION WITH DIFFERENT LEVELS OF INTENSITY

The aim of the study was to evaluate the economic efficiency of spring triticale varieties at different levels of production intensity. Three-year field results for the years 2017, 2018 and 2020 were used for the calculations. Factors such as tillage methods (conventional and reduced tillage), varying levels of nitrogen fertilisation (0, 70 and 100 kg N/ha) and varieties – Sopot and Milewo – were included in the analysis. Direct surplus was used as a measure of economic efficiency. The economic efficiency of spring triticale cultivation was assessed taking into account the use of one of the main production factors, i.e. land. For individual variants of the experiment, the gross profitability index was calculated as the ratio of production value to direct costs. The analysis of the production-economic indices showed that the technology with the use of traditional tillage (plough) and a nitrogen fertilisation rate of 70 kg N/ha were the more favourable variant for spring triticale cultivation. It was also found that the level of obtained direct surplus was more influenced by the level of obtained yields and purchase prices of triticale than by the level of direct costs incurred for tillage and sowing operations.

Measurement and decomposition of China's real economic growth efficiency under environmental constraints

From the perspective of economic growth efficiency, this paper adopts the traditional DEA-Malmquist index method and the SBM-ML index method considering undesired output to measure the growth efficiency of China’s real economy with or without environmental constraints. The results show that: (1) From 2005 to 2017, the total factor productivity of China's real economy increased by 2.7%, but under environmental constraints, the total factor productivity of China’s real economy decreased by 0.6%, mainly due to the “drag” of the growth efficiency of the real economy by technological changes. Second, without considering the unintended output, 76.67% of the provinces and cities have improved the growth efficiency of the real economy, and 93.33% have made technological progress. Third, under environmental constraints, the total factor productivity and technological progress showed an upward trend only in the central region, while all other regions showed a downward trend to varying degrees. The descending range is east > northeast > west.

STATISTICAL ANALYSIS ON THE POTENTIAL ANTIFUNGAL ACTIVITY OF SOME ESSENTIAL OILS OBTAINED FROM MEDICINAL PLANTS

The paper presents descriptive statistics of the experimental results regarding the potential antifungal activity of four essential oils obtained from new varieties of medicinal plants created in Romania (Yellow basil, Red basil, Marigold and Hyssop). Efficacy tests were performed on the phytopathogenic fungus Fusarium oxysporum ZUM 2407, using four concentrations, each with four repeats. It was observed the direct dependence of the efficacy of the antifungal action of the essential oils depending on the concentration used, but also its decrease in time, due to volatilization and consumption in the control process. It was established that the action of the studied essential oils is rather fungistatic for all the analyzed variants. Based on the efficacy of the antifungal action of those four essential oils, the analyzed variants could be ranked as attack intensity and a measure of economic efficiency was developed in order to further apply these solutions in agricultural practice

Measurement and Convergence Test of Green Economic Efficiency of the Yangtze River Economic Belt Under Different Spatial Network Correlation

The green and coordinated development of the Yangtze River Economic Belt (YREB) is of great significance to the overall high-quality growth of the Chinese economy. Targeting green developmental issues and regional disparities in the YREB, this article proposes a method that combines the Super-EBM and Malmquist–Luenberger indexes to measure the green economic efficiency (GEE) of 108 cities from 2003 to 2018. Moreover, we adopted the dynamic spatial Durbin panel model to conduct a convergence test including economic linkage, capital liquidity, talent mobility, and information sharing. The outcomes pointed out that 1) the green economy shows a volatile growing trend, and technological progress is the main source of the YREB’s GEE; 2) we have noticed the formation of spatial differentiation in the three basins, especially in the central areas of big cities such as Shanghai, Hangzhou, Wuhan, and Chongqing; 3) the GEE follows a global β-convergence trend that narrows the gap in green economic efficiency. More specifically, the downstream (11.48%) has the fastest convergence rate, followed by the midstream (8.09%) and upstream (7.97%); 4) capital liquidity, governance, and economic openness contribute a lot to maintaining the convergence trend. The primary contributions of this study are the policy recommendations to promote green development and narrow the gap in the YREB to ultimately achieve effective coordinated development.

Heterogeneous environmental regulations and green economic efficiency in China: the mediating role of industrial structure.

Industrial upgrading is the key to promoting green economic efficiency. Coordination between environmental regulations and industrial structure can lead to sustainable economic growth. However, insufficient attention has been paid to the mechanism by which environmental regulation (ER) promote green economic efficiency (GEE) under the mediating role of industrial structure optimization. Using robust and comprehensive measures of green economic efficiency, we assess how various environmental regulations affect green economic efficiency as well as the intermediate effect of industrial structure of a certain province with provincial panel data during the period 2003-2017. The results of dynamic panel two-step system generalized method of moments (GMM) confirm the heterogeneous effects of the three types of ER, namely control-and-command regulation, market-based regulation, and voluntary regulation on GEE in China. The spatial analysis demonstrates that control-and-command and voluntary regulations significantly accelerate GEE in inland provinces, while they have insignificant effect in coastal provinces. Based on the mediating analysis, we find that market-based regulation is conducive to GEE through both advanced and rationalized industrial structure, whereas control-and-command regulation improves GEE through advanced industrial structure only. The voluntary-based regulation on one hand stimulates GEE through advanced industrial structure, but on other hand impedes it through rationalized industrial structure. The results could provide critical insights and a theoretical basis for policy makers in reasonable optimization of industrial structure and guaranteeing green economic efficiency.

How are the United States Banks faring during the COVID-19 Pandemic? Evidence of Economic Efficiency Measures

Abstract Due to the current lockdown and restrictions related to the COVID-19, U.S. commercial and domestic banks are facing cashflow and financial difficulties. This has led to many vulnerable customers losing their source of income. In this paper, we examine the importance of financial liquidity and solvency on U.S. commercial and domestic banks’ efficiency during the COVID-19. This paper adopts the Data Envelopment Analysis’ estimator in a two-step procedure. First, economic efficiency measures of 16,830 December quarterly observations of U.S. commercial and domestic banks are estimated from December 2010 to December 2020. Within each year, 1,530 U.S. commercial and domestic banks are selected. Second, using Tobit and panel fixed effect regression models, the importance of both liquidity and solvency risks on economic efficiency during the COVID-19 is examined. Empirical estimates indicate that both liquidity and solvency financial factors negatively affect the economic efficiency measures of U.S. commercial and domestic banks during the COVID-19.

THE ECONOMIC EFFICIENCY OF PRODUCTION OF A TRITICALE HYBRID GENETIC LINE AT DIFFERENT LEVELS OF INTENSITY

The aim of the study was to evaluate the economic efficiency of production of a hybrid genetic line of winter triticale in comparison with a short-straw form, at different intensity levels under cereal crop rotation conditions. Calculations were made based on three-year (2017-2019) field trial results. The analysis included tillage methods (traditional and simplified), differentiated nitrogen fertilization (0,90 and 120 kg N/ha) and two forms of triticale: The rotondo variety and the hybrid genetic line – BOH 2415. The gross margin was taken as a measure of economic efficiency. The economic effectiveness of cultivation of both forms of winter triticale was assessed from the perspective of utilizing one of the basic production factors, i.e., land. The gross profitability index for particular variants of the experiment was also calculated as the relation of production value to direct costs. The analysis of production and economic indices showed that the more favorable variant of winter triticale cultivation was hybrid form cultivation technology with the use of traditional tillage (plough) and a nitrogen fertilization rate at a level of 120 kg N/ha. The level of the obtained gross margin was more influenced by the level of the obtained yield and the purchase price of triticale than by the level of incurred direct costs depending on the soil tillage method.

Effects of dietary fish oil supplementation in the diet on performance of Broiler chicks

This work was carried out to investigate the effect of dietary supplementation of fish oil on growth performance, carcass quality, immunological and serum biochemical parameters, total antioxidant capacity, intestinal morphology, mortality ratio and economic efficiency measures of broiler chicks. A total of 150 (ross 308) one day old chicks was distributed into 5 groups each contains 3 replicates (10 chicks/ replicate) fed on Five experimental diets contains different level of oils (0 oil, 1(SBO &amp; FO), 2 FO and 3% FO respectively), during the experimental period (5 weeks). four chicks from each replicate were used for analysis of the experimental chicks. The results revealed that supplementation of fish oil in diets of broiler chicks 1,2 and 3 % improve (P&lt; 0.05) the body weight (Bw) and body weight gain (BWG) than control groups but the best value were observed in 1&amp;3% fish oil group beside improvement of feed conversion ratio (FCR) in all groups fed fish oil than control groups. However, numerically increased feed consumption in 1% SBO fed group than other groups. Significant (P&lt; 0.05) improvement of carcass characteristics and dressing percentage gradually with fish oil supplementation. The values of USFA and n-3 PUFA were significantly (P&lt; 0.05) higher in the breast muscle of broilers fed with fish oil compared to the control groups. But, SFA significantly (P&lt; 0.05) decreased with fish oil than control groups. No significant difference in n-6 PUFA value between SBO and FO groups. So, N- 6:N3 ratio in breast meat decreased gradually with FO addition. Also, triglycerides, cholesterol, LDL and VLDL concentrations were significantly (P&lt; 0.05) reduced by fish oil treatments, but serum HDL-c, total protein (TP), and globulin (GL) concentrations were significantly (P&lt; 0.05) increased by using diets containing fish oil. Also, provision of fish oil Significantly (P&lt; 0.05) improves immune response in broilers chicken against Newcastle virus vaccine through increase antibody titer and TLC with decreased mortality rate. Significant (P&lt; 0.05) improvement of intestinal morphology with fish oil supplement were detected. The highest economic efficiency was recorded in group fed 1% FO followed by 1% SBO, 2% FO, 3% FO,0% oil gradually. from the present study, it could be concluded that the supplementation of fish oil in chick's diets significantly improve the growth performance, body composition, immune response, serum biochemical parameters, intestinal morphology, decrease the mortality rate and economically efficient at rate 1% addition
