Authors: Chandra M.Andi , Pambudi Didik Rio , Fitriyanti Fitriyanti , Kholilah Siti , Jamalluddin Wahyudin Bin
Published: September 2023

Background: Acne (acne vulgaris) is still a major health problem. Treatment with antibiotics raises problems in the form of resistance, irritation, and immune hypersensitivity. Alternatives derived from natural ingredients are needed to avoid these problems, namely Dayak onions. Objective: To find out the activity of the ethanol extract of onion bulbs in inhibiting the growth of P. acnes based on the variation of the incubation time duration of the bacteria as well as the solvent. Method: Phytochemical screening tests looked for alkaloids, flavonoids, phenols, steroids, tannins, and saponins. Testing of the extract’s ability to inhibit bacteria was carried out with variations in the incubation times (24 and 48 hours) and solvents, namely Na-CMC and DMSO. The bacteria growth inhibition test employed the well-diffusion method, and the resulting data was analyzed using SPSS software. Results: Dayak onion extract contains alkaloids, saponins, flavonoids, and triterpenoids. Na-CMC solvent obtained the highest inhibition ability of Dayak onion extract at a concentration of 40% with an inhibition value of 10.12±1.840mm (24 hours), and 11.575±1.694 mm (48 hours) while DMSO solvent showed the highest inhibition at a concentration of 20% with inhibition values of 15.48±1.198 mm (24 hours) and 15.91±1.625 mm (48 hours). Interpretation of the results of the Wilcoxon test based on ranking showed a positive difference at 48 hours of incubation. Conclusion: The optimal incubation time of P. acnes was 48 hours with dimethyl sulfoxide (DMSO) as the best solvent.

Published: September 2023

Background: There are several ways to treat breast cancer, one of which is administering chemotherapy agents. Chemotherapy agents have activity in inhibiting the cell cycle. That will affect the effectiveness of therapy and the side effects of chemotherapy agents.
Objective: This study aimed to evaluate single and combination chemotherapy agent therapeutic efficacy and side effects
Method: The design of this study used an observational cohort study with retrospective data collection from January to December 2019. Patients obtained from medical records were diagnosed with metastatic stage of breast cancer at Panti Nirmala Hospital, Malang. The effectiveness of the chemotherapy agent was seen from the carcinoembryonic antigen (CEA) and cancer antigen 15-3 (CA15-3), which were carried out in the first and third cycles, then analyzed using the Wilcoxon and U-Mann Whitney tests. Side effects of chemotherapy agents were analyzed descriptively.
Results: Analysis of the Wilcoxon test showed differences between the two groups of chemotherapeutic agents in CEA and CA15-3 (p<0.05). U-Mann Whitney test analysis showed no difference after administration of the two groups of chemotherapy agents at CEA (p>0.05). However, there was a difference in CA15-3 (p<0.05). Both chemotherapy agents showed most common side effects such as pain, nausea,  vomiting, and alopecia.
Conclusion: Patients who received a combination of chemotherapy agents had lower CA15-3 levels than single chemotherapy agents.

Authors: Bagis Abdul Azis , Sukma Akram , Nururly Santi
Published: September 2023

Purpose ─ This paper aims to examine the role of entrepreneurial orientation for SMEs in building business continuity in eastern Indonesia and highlight strengthening government support for the sustainability of post-covid SME entities.
Design/methodology/approach ─ A random sampling approach was used to select the respondents, with closed questions used for a sample of 400 SME owner-managers in eastern Indonesia using the structural equation modelling technique (PLS-SEM).
Findings ─ The results show that the ability of SME owner-managers to build business longevity is determined more by their strong entrepreneurial orientation than by government support. In the context of this study, the government’s support policy for SMEs in eastern Indonesia is ineffective.
Limitations/research implications – This research selects the characteristics of the living company by Geus, which positions business entities as living beings, as an indicator of business longevity.
Practical implications - Based on research results, the sustainability of SMEs in eastern Indonesia can be built based on the owner-managers entrepreneurial orientation. Meanwhile, government support still needs to be maximized.
Originality/value ─ The contribution of three determinants of government support to SMEs is analyzed to determine the acceleration of the survival of SMEs after Covid.
VIRTUAL MEDIATION IN DIVORCE CASES AT UJUNG TANJUNG RELIGIOUS COURT
Authors: Nur Aisyah Siti
Published: September 2023

The mediation process was initially carried out outside the court institution (non-litigation) for the parties to the dispute, but with the times and changes in behavior, a mediation process was made in court that was inseparable from the court institution (litigation). The mediation process is an obligation that must be carried out by the judge before carrying out the next trial. If you look at PERMA No. 1 of 2016, there are many advantages why mediation is used in court. The purpose of this study is to understand the problems faced in virtual mediation at the Ujung Tanjung Religious Court and describe the efforts made by law enforcement of the Ujung Tanjung Religious Court in handling virtual mediation problems in terms of the effectiveness of Soerjono Soekanto. qualitative approach. The conclusion of this study is that the low success of the community itself is that not all parties in this case use the services of advocates, and the average level of education of the parties is low. The Ujung Tanjung Religious Court in carrying out its duties and functions has carried out a mediation process based on PERMA No.1 of 2016, the results of the litigants in conducting the mediation process are still low and the parties' strong desire to divorce. The Ujung Tanjung Religious Court has made efforts to resolve the issue, but it still requires awareness and responsibility. The online mediation process itself if referring to the Supreme Court Rules, the process can be done using audio-visual media such as video calls that are already available in many applications. In other words, the role or function of this paper is expected to be able to be a social construction to find the level of effectiveness of mediation in divorce cases in religious courts.

Authors: Torres-Riera Sonia , Arboix Adrià , Garcia-Eroles Luís , Sánchez-López María-José
Published: September 2023

Background: The oldest old people (≥ 85 years) represent the fastest growing age group in Western populations. Knowledge on early outcomes of acute ischemic stroke (AIS) in very old female patients remains limited. Methods: We assessed gender differences and female-specific clinical data and in-hospital mortality in very old patients with AIS. Acute cerebral infarction was diagnosed in 506 very old female patients from a total of 4,600 acute cerebrovascular infarctions available in an ongoing 24-year hospital stroke data bank. A comparative analysis of vital status at discharge (alive versus dead) was performed in terms of cardiovascular risk factors, clinical data, and early outcomes. Results: The overall in-hospital mortality rate was 20.4%. In multivariate analysis, sudden onset, altered level of consciousness, and neurological, respiratory, cardiological or hemorrhagic complications, and lacunar infarcts appeared to be independent predictors of in-hospital mortality. Conclusions: Female patients ≥85 years with AIS are an unfavorable subgroup of stroke patients with a high risk of early mortality, which may be due to comorbidity, stroke subtype distribution, and higher frequency of medical complications. However, the presence of lacunar infarcts showed a significant protective effect.
Mathematical Method of Rational Placement of Gas Fire Sensors
Authors: Petrov Andrey Eugenievitch
Published: September 2023

Ensuring fire safety is an important condition for the successful operation of industrial enterprises. It is necessary to detect the threat of fire before ignition. An indicator of danger is the appearance of gas, which occurs as a result of unauthorized heating of equipment. Gas sensors make it possible to detect the appearance of gases characteristic of the decomposition of materials at the stage of smouldering and pyrolysis, which cause a change in the composition of the atmosphere. This paper presents a mathematical method for the rational placement of gas analyzers for premises of potentially hazardous industries. It is the rational placement of gas sensors, which ensures safety, taking into account economic feasibility that determines the effectiveness of their use. For the first time, the analysis of gas accumulation during the movement of the flow from the source to the ceil-ing, then propagation to the location of the sensors, is used for the first time to select the placement of gas sensors. Depending on the permissible values of the gas volume, the placement and number of gas sensors are selected. The calculation of the conditions for the rational placement of gas sen-sors for the most common indicators, such as carbon monoxide and hydrogen at different sizes and heights of rooms, is carried out. The method of calculating the location of gas analyzers makes it possible to diagnose and predict fire hazard at technological facilities on the basis of gas control, and compare the obtained values with the maximum permissible values. This method provides cal-culation of the coordinates of the gas source from the coordinates of the triggered sensors. Knowing the coordinates of all sensors, the coordinates of the sensors that gave the alarm, and the formula for determining the volume of the gas cloud under these sensors, it is possible to assess the localization of the source of dangerous gas in the protected room. This increases the efficiency of the fire safety system. The method makes it possible to control the layout of sensors depending on the volume of protected premises, types of production, the creation of new sensors, changes in the composition of hazardous gas in different technological conditions.

Authors: Fan Jingchao , Liu Guanghui , Wang Kai , Xie Chun , Kang Zhuangli
Published: September 2023

The changes in storage loss, water distribution status, gel characteristics, TBARS, total volatile basic nitrogen, and total plate count of cooked reduced-phosphate silver carp surimi batter during cold storage at 4 °C were investigated. The storage loss, content of free water, pH, hardness, TBARS, total volatile basic nitrogen value and total plate count of all cooked reduced-phosphate silver carp surimi batters significantly increased (P < 0.05) with increasing the cold storage time. Meanwhile, the content of immobilized water, whiteness, springiness, and cohesiveness decreased significantly (P < 0.05). At the same cold storage time, the sample of cooked reduced-phosphate silver carp surimi batter has lower water mobility, darker colour and better texture characteristics, but the values of TBARS, total volatile basic nitrogen and total plate count were not significantly different (P > 0.05). To sum up, the use of potassium bicarbonate instead of sodium tripolyphosphate could produce the cooked reduced-phosphate silver carp surimi batter with better water holding capacity and gel characteristics during cold storage.

Authors: Tang Yulong , Li Jiangning , Lu Zhiyi , Wang Yunan , Tao Kai , Lin Yichao
Published: September 2023

Water electrolysis is a compelling technology for the production of environmentally-friendly hydrogen, minimizing carbon emissions. The electrolysis process of water heavily relies on the effective and steady oxygen evolution reaction (OER) taking place at the anode. Herein, we in-troduce a highly promising catalyst for OER called CoSe2@NiFeOOH arrays, which are supported on a nickel foam. This catalyst, referred to as CoSe2@NiFeOOH/NF, is fabricated through a two-step process involving the selenidation of a Co-based porous metal organic framework and subsequent electrochemical deposition on a nickel foam. The CoSe2@NiFeOOH/NF catalyst demonstrates outstanding activity for the OER in an alkaline electrolyte. It exhibits a low over-potential (η) of 254 mV at 100 mA cm−2, a small Tafel slope of 73 mV dec−1, and excellent high stability. The high performance of CoSe2@NiFeOOH/NF can be attributed to the combination of the high conductivity of the inner layer and the synergistic effect between CoSe2 and NiFeOOH. This study offers an effective method for the fabrication of highly efficient catalysts for the OER.

Authors: Jing Linlong , Wei Xinhua , Song QI , Wang Fei
Published: September 2023

Rice canopy height and density are directly usable crop phenotypic traits for the direct estimation of crop biomass. Therefore, it is crucial to rapidly and accurately estimate rice canopy phenotypic parameters. To achieve non-destructive detection and estimation of essential phenotypic parameters in rice, a platform based on LiDAR point cloud data for rice phenotypic parameter detection was established. Data collection of rice canopy layers was performed across multiple plots. The LiDAR-detected canopy top point clouds were selected using a method based on the highest percentile, and the rice canopy surface model was calculated. Canopy height estimation was the difference between ground elevation and percentile value. To determine the optimal percentile defining the rice canopy top, testing was conducted incrementally from 0.8 to 1 with an increment of 0.005. The optimal percentile value was found to be 0.975. The root mean square error (RMSE) between LiDAR-detected canopy height and manually measured canopy height was calculated. The prediction model based on canopy height (R2=0.941, RMSE=0.019) exhibited a strong correlation with actual canopy height. Linear regression analysis was conducted between gap fraction of different plots and manually detected average Leaf Area Index (LAI) of rice canopy. Prediction models for canopy LAI based on ground return counts (R2=0.24, RMSE=0.1) and ground return intensity (R2=0.28, RMSE=0.09) showed strong correlations but had lower correlation with rice canopy LAI. Regression analysis was performed between LiDAR-detected canopy height and manually measured rice canopy LAI. The results indicated that the prediction model based on canopy height (R2=0.77, RMSE=0.03) was more accurate.

Authors: Gardner Robert , Gladin Matthew
Published: September 2023

Motivated by results on the location of zeros of a complex polynomial with monotonicity conditions on the coefficients (such as the classical Eneström-Kakeya Theorem, and its recent generalizations), we impose similar conditions and give bounds on the number of zeros in certain regions. We do so by introducing a reversal in monotonicity conditions on the real and imaginary parts of the coefficients, and also on their moduli. The results presented naturally apply to certain classes of lacunary polynomials.

Authors: Denysova Alla , Zhaivoron Oksana
Published: September 2023

In the article analytical studies of the efficiency of heat pumps in the thermal schemes of thermal and nuclear power plants for centralized heating and hot water supply systems taking into account the climatic conditions of Ukraine have been carried out. This task meets the objectives of energy saving and reduces emissions of harmful substances into the environment. The main focus is on improving the efficiency of the heat pump power supply system, which integrates an alternative energy source. An analysis of the exergy parameters of heat pump cycles has been performed, which have made it possible to establish that the most efficient working fluid of the cycle is freon R152a, at which the highest heat pump conversion coefficient and the lowest compressor power indicator are achieved. Ways and methods leading to reduction to underproduction of the electricity by turbine of of power plant and to increasation of the efficiency of a steam turbine cycle are proposed. It is shown that the efficiency of the system is most affected by losses in the evaporator, so the efficiency of this element of the heat pump should be given the most attention when using the energy of circulating water. An additional aspect of the novelty of the proposed method lies in the possibility of further optimization of the technical and economic parameters of the power system. A methodology based on the use of the exergy method of analysis to substantiate the conditions for the rational use of heat pumps for power plants in the utilization of low-grade heat of circulating water for cooling the turbine condensers is proposed, which can be considered as innovative way. Results open the further prospects for the development of heat pump heat supplyhas been proposed.

Authors: Prishchenko Olga , Chernogor Tetyana
Published: September 2023

The article deals with the construction of a mathematical model of the process, which is created based on the results of a full factorial experiment. Often, only the results of experimental studies carried out at such objects are the information, based on the processing of which, according to the obtained mathematical model of the object, a high-quality control algorithm for this object can be implemented. At the same time, the construction of a mathematical model that describes the technological process with the required accuracy often involves a huge amount of work at the stage of experiments. The task of planning experiments is to establish the minimum required number of them and the conditions for their implementation, to choose methods for mathematical processing of the results, and to make decisions. Designing experiments significantly reduces the number of experiments required to obtain a process model. An active experiment involves a purposeful choice of factor values. Compared to a passive experiment, such an experiment turns out to be more efficient and economical, since the amount of experimental work is significantly reduced. In this article, in relation to chemical technology, the issues of organizing an experiment, mathematical processing of experimental data and mathematical planning of an experiment in the search for optimal conditions for conducting a technological process are described. Mathematical modeling and optimization of chemical technology objects is of great importance for obtaining higher professional education for students of the Educational and Scientific Institute of Chemical Technology and Engineering.

Proposed Conceptual Framework for Studying Non-Users Rice Farmers' Intention to Use Commercial Biopesticides Products
Authors: Istriningsih  , Sumarwan Ujang , Hartoyo  , Suharjo Budi
Published: September 2023

Commercial biopesticide products have been developed for a long time in Indonesia, but until now the level of application is still relatively low. This paper aims to determine the factors that are expected to influence the intention of non-users rice farmers to use commercial biopesticide products. Furthermore, a conceptual framework of intention to use commercial biopesticide products is proposed. Based on the literature review of previous empirical studies in various contexts, this paper has explored the factors that influence the intention of using biopesticides. Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) is employed as the main theoretical basis in this study which can be extended with relevant constructs to the research context (extended UTAUT2). The proposed conceptual framework recommends that non-users rice farmers' intention to use commercial biopesticide products is expected to be influenced by variables namely performance expectancy, effort expectancy, social influence, facilitating condition, price value, perceived need, information publicity, and product marketing. This integrative conceptual framework is expected to have a theoretical contribution to understand the factors of non-users rice farmers’ intention to use commercial biopesticide products. In addition, it is beneficial for policymakers and managers to formulate and implement strategies to increase rice farmers' intention to use commercial biopesticide products.

Authors: Ida Bagus Gede Arsa Wedhana , Luh Putu Mahyuni
Published: September 2023

This study aims to empirically examine the factors that influence the intention or interest of coffee shop consumers to use QRIS in Denpasar, Bali. By understanding the factors that shape coffee shop consumer interest in using QRIS, it is hoped that the implications for business practices and policies will be more effective. Empirical data was collected by distributing questionnaires online involving 446 respondents and analyzed using SmartPLS3. This study provides empirical evidence that consumers' intention to use QRIS is positively and significantly influenced by perceived benefits and socialization. This study also found that socialization related to QRIS was positively and significantly influenced by perceived benefits and obstacles of QRIS, besides that the role of socialization was able to mediate perceptions of benefits on coffee shop consumer intentions in using QRIS. Perceived obstacles have a negative relationship to intentions, but both do not have a significant effect as well as the role of socialization which is unable to mediate between perceived QRIS barriers to intentions. This indicates that the benefits offered by QRIS with ongoing socialization regarding the benefits of QRIS are able to make consumers intend to use QRIS. The findings of this study have implications for policy makers to improve the security features of QRIS and increase socialization regarding the safety of using QRIS.

Third, for the patrician class, consumer motives for purchasing products are not related to counterfeit products and subtle brand prominence.
Overestimation of conformity assessment risks in legal requirements of weighing instruments
Authors: Purata-Sifuentes Omar-Jair , Purata-Funes Elvia-Andrea , Foyer Gisa
Published: September 2023

This paper examines the risks for producers and consumers of non-automatic weighing instruments. It compares two scenarios: one where only the maximum permissible error requirement of the standard weights is considered during the computation of measurement uncertainty and another where the standard uncertainty of the weights is also involved. By quantifying these risks, the study sheds light on the potential implications for both producers and consumers. The results shows that in general, the producer and consumer risks are both wrongly estimated for the use of only the maximum permissible error location criterium. The overestimation founded reached levels higher than 20 %.
Umbrales de resistividad para evaluar durabilidad del hormigón con hidrofugantes y diferentes relaciones agua/cemento
Authors: Guzmán Alberto
Published: September 2023

En el presente trabajo se evalúa cómo influye en la resistividad eléctrica del hormigón la variación de la relación agua/cemento; el tipo de cemento seleccionado (CPP y CPF); y la incorporación de un hidrófugo. Se confeccionaron probetas cilíndricas sobre las que fue evaluada la resistividad mediante el método de la sonda de Wenner. Comparando los resultados obtenidos con los valores umbrales indicados en la literatura, se permite entender la importancia que frente a este mecanismo de degradación implica limitar a 0.45 la máxima relación a/c.

Introduction:

The ideal procedure for isolated patellofemoral arthritis is a controversial topic. Patellofemoral arthroplasty (PFA) is an option that aims to restore normal kinematics to the knee while preserving bone. PFA has been shown to have benefits compared with total knee arthroplasty (TKA) in this patient population but has historically had a high failure rate. Revision rates are improving with modern implants and tight indications but still remain higher than TKA. This review summarizes current thinking around PFA using modern implants and techniques in 2023, provides an implant-specific analysis, and assesses how we can improve outcomes after PFA based on the current literature. The aim was to provide an outline of the evidence around PFA on which surgeons can make decisions to optimize patient outcome in this young and active population.

Methods:

Four databases (MEDLINE, Embase, Scopus, and SPORTDiscus) were searched for concepts of patellofemoral joint arthroplasty. After abstract and text review, a screening software was used to assess articles based on inclusion criteria for studies describing indications, outcomes, and techniques for isolated PFA using modern implants, with or without concomitant procedures.

Results:

A total of 191 articles were included for further examination, with 62 articles being instructional course lectures, systematic reviews, technique articles, narrative reviews, expert opinions, or meta-analyses. The remaining articles were case reports, trials, or cohort studies. Articles were used to create a thorough outline of multiple recurrent topics in the literature.

Conclusions:

PFA is an appealing option that has the potential to provide a more natural feeling and functioning knee for those with isolated PF arthritis. The high rate of revision is a cause for concern and there are several technical details that should be stressed to optimize results. The uncertain outcome after revision to TKA also requires more investigation. In addition, the importance of strict selection criteria and firm indications cannot be stressed enough to optimize longevity and attempt to predict those who are likely to have progression of tibiofemoral osteoarthritis. The development of new third-generation implants is promising with excellent functional outcomes and a much lower rate of maltracking and implant complications compared with earlier generations. The impact of these implants and improvement in surgical techniques on the revision rate of PFA will be determined from longer-term outcomes.

Terry Palisch will take office as 2024 SPE President during the 2023 SPE Annual Technical Conference and Exhibition in October. The following is a transcript of his podcast episode recorded with Pam Boschee, SPE director of magazines, for this month’s Journal of Petroleum Technology.

In this inaugural podcast episode and transcript, we discussed Palisch’s views of the challenges facing our industry and SPE members, his outlook for our industry, and what his goals will be during his presidency.

Welcome to the Society of Petroleum Engineers podcast with 2024 President Terry Palisch. I’m Pam Boschee, director of SPE magazines, and Terry joins me today to share his thoughts about being named president with the official passing of the baton from 2023 President Med Kamal at our Annual Technical Conference and Exhibition (ATCE) in San Antonio in October.

Terry is the vice president of technology and engineering at Carbo Ceramics in Richardson, Texas. He began his career with Arco during which he served 10 years in Alaska and 4 years as a senior petroleum engineering advisor in Algeria. He joined Carbo in 2004, and in his current position leads a team of technologists developing and championing new products and services and advising clients in completion and fracture optimization.

He has been an SPE member for more than 40 years, serving in various roles including past chairman of the SPE Dallas Section. He has been the past chair of the ATCE technical program and the former SPE Completions Technical Director. He is an SPE Distinguished Member and received the award for Distinguished Service as well as the SPE Mid-Continent Regional Completions Optimization and Technology Award and the Regional Service Award. In 2013 he was named one of the top 15 best engineers by the Texas Independent Producers and Royalty Owners Association, and in 2015 he was named the SPE Dallas Section Engineer of the Year. He has authored more than 50 SPE technical papers and holds several patents.

He holds a bachelor’s degree in petroleum engineering from the University of Missouri Rolla, now the Missouri University of Science and Technology, and was recently recognized as a distinguished alumnus.
Test Shows Fracturing Can Also Create Underground Water Heating Systems

Fervo Energy has shown that fracturing can be used to build a geothermal heating system in hot, hard rock.

During a 37-day test at its Project Red test site, the Houston company produced as much as 63 L/s (998 gal/min) of water heated to 336°F. By pumping water from an injection well through fractured hot rock to a producing well, it heated enough water to generate up to 3.5 MW of power, according to a company release.

In a world where demand is commonly measured in gigawatts, that’s not much, but it is more than double the highest flow rate from tests going back decades. And unlike those earlier tests, the company has a clear path to heating higher volumes and lowering the cost.

“I think this is just a big moment for both our company, but also the industry at large, to finally have this proof point where we can deliver commercial levels of permeability and flow rates for these wells,” said Jack Norbeck, co-founder and chief technical officer for Fervo.

The idea of injecting water through hot rock has been around for decades as a way to create enhanced geothermal systems (EGS), but this is the first time someone has achieved this level of flow and is moving next to create a group of geothermal wells for commercial generation.

Fervo has taken methods developed to extract oil and gas from ultratight rock and shown they can be used to do something quite different.

“Overall, there’s nothing really surprising here—they used a pretty standard shale frac design and observed pretty similar performance from what you would see in a shale play. Or at least, what you’d expect if you used a shale well as a long-term water injector and circulated fluid over to a neighboring production well,” said Mark McClure, chief executive of ResFrac, a reservoir modeling and consulting firm, in a blog post.

This fracturing-based option poses a challenge to EGS researchers who live in countries where completions using oil industry fracturing techniques are not an option.

“The EGS community has conventionally been focused on ‘stimulating natural fractures,’ and this has led them to use fracture designs that would be considered suboptimal, from the perspective of oil and gas field experience,” McClure said.

What Fervo has done is show that fracturing can be used to get past a barrier blocking EGS development using current fracturing technology.

“The breakthrough is that someone actually had the guts and organization to go out and do it,” McClure said.

Those at Fervo, though, have little time to celebrate the milestone as they focus on improving those methods to economically produce geothermal energy.

“In successfully completing this project, we have demonstrated that no major technical barriers exist to deploying horizontal EGS in similar meta-sedimentary or igneous formations to temperatures of approximately 400°F,” according to a Fervo paper.

That feat was recognized by a leader at the FORGE test site, which is also doing EGS research and development with substantial financial support from the US Department of Energy.
