Research on optimal placement of low‐carbon equipment capacity in integrated energy system considering carbon emission and carbon trading

Integrated energy system (IES) can improve energy efficiency, reasonable configuration of low‐carbon equipment in IES can effectively reduce carbon emissions and achieve carbon peaking and carbon neutrality. Under the background of carbon peaking and carbon neutrality, this paper proposes a configuration method of low‐carbon equipment in IES considering life cycle carbon emissions and ladder‐type carbon trading cost. Firstly, the IES architecture of animation and cartoon industry parks in Sino‐Singapore Tianjin eco‐city is analyzed, and the models of “electrical/heating/cooling” energy supply equipment and integrated energy storage equipment are built. Secondly, the two‐stage operation of power to gas (P2G) is refined, and P2G is subdivided into equipment combination of electrolyzer, methanation reactor, hydrogen fuel cell to study the various benefits of hydrogen energy. Then, the life cycle carbon emission calculation method of renewable energy power generation and P2G equipment is proposed, the life cycle carbon emission model of IES is established, and the ladder‐type carbon trading mechanism is introduced to restrict IES carbon emission. On this basis, aiming at minimizing carbon emission cost, energy purchased cost, equipment investment, operation and maintenance cost, and renewable energy power generation curtailment cost, a joint optimal configuration model of renewable energy power generation and P2G is established in order to realize the low‐carbon economic operation of IES. Finally, through multi‐scenario comparative analysis, the correctness and effectiveness of the optimal configuration method of low‐carbon equipment in IES are verified, and the influence of carbon trading mechanism and refining two‐stage operation of P2G on the optimal configuration results are discussed.

A CRITICAL COMPARISON OF BRAVE BROWSER AND GOOGLE CHROME FORENSIC ARTEFACTS

Digital forensic practitioners are tasked with the identification, recovery, and analysis of Internet browser artefacts which may have been used in the pursuit of committing a civil or criminal offence. This research paper critically compares the most downloaded browser, Google Chrome, against an increasingly popular Chromium browser known as Brave, said to offer privacy-by-default. With increasing forensic caseloads, data complexity, and requirements for method validation to satisfy ISO 17025 accreditation, recognising the similarities and differences between the browsers, developed on the same underlying technology is essential. The paper describes a series of conducted experiments and subsequent analysis to identify artefacts created as part of normal user browsing activity. Analysis of the artefacts found that Brave and Chrome share almost identical data structures, with on-disk artefact recovery successful, even for deleted data. The outcome of this research, based upon the results, serves to enrich understanding and provide best practice for practitioners and software developers, respectively responsible for examining Chromium artefacts for use in evidence production and developing new forensic tools and techniques.

Growth Differentiation Factor-15 Based ABC (Age, Biomarkers, Clinical History)-AF (Atrial Fibrillation)-Bleeding Risk Score for Elderly Patients with Nonvalvular Atrial Fibrillation

Background Growth differentiation factor-15 (GDF-15) is a strong predictor of bleeding in atrial fibrillation (AF) patients. The novel ABC (age, biomarkers, and clinical history), AF, and bleeding risk score outperforms HAS-BLED bleeding risk score for major bleeding (MB) in patients with AF receiving oral anti-coagulation in the clinical trial cohort. However, it has not been entirely externally validated. We aimed to refine and understand the application of the ABC-AF bleeding risk score in elderly (aged ≥65 years old) patients with nonvalvular atrial fibrillation (NVAF) for predicting the different types of bleeding events and anti-thrombotic treatments. Methods We identified elderly patients with NVAF between March 2018 and December 2019 who were hospitalized for the first time after a diagnosis of NVAF. We measured the plasma concentration of the ABC biomarkers (growth differentiation factor 15 (GDF-15) and cardiac troponin-T (cTnT)) from enrolled patients. We collected their general information and follow up for one year until December 2020. During the follow-up period, information on the occurrence of bleeding events (major bleeding, clinically relevant nonmajor gastrointestinal bleeding (CRNM GIB), and minor bleeding events) was collected. Results We enrolled 342 elderly NAVF patients; the ABC-AF bleeding and HAS-BLED scores were quantified. With an average of 1.5 years of follow-up, 6 patients had an intracranial hemorrhage; 57 patients had CRNM GIB; and 68 patients had minor bleeding events (36 fecal occult blood positive and 32 other minor bleeding events). The ABC-AF bleeding score yielded a C-index of 0.72 (95% CI 0.60–0.84) for predicting MB in elderly patients with NAVF, C-index of 0.69 (95% CI 0.57–0.82) by HAS-BLED score. Comparison of the incidence of bleeding events during follow-up and the predicted 1-year incidence of bleeding events by each bleeding risk score, ABC-AF bleeding, and HAS-BLED scores have similar value in predicting the risk for elderly patients with NAVF in different types of bleeding events, whether on oral anti-coagulation treatment (OAC) or non-OAC (P > 0.05). Conclusion In elderly patients with NVAF, the biomarker-based ABC-AF bleeding score showed similar performance compared with the HAS-BLED bleeding risk score.
An observational descriptive study of pattern of pathological changes in liver in context of medico-legal autopsy done at J. L.N. Hospital, Ajmer

BackgroundAutopsy finding in liver with pathological changes are studied. Aim and ObjectivesTo correlate histopathological findings in the liver with gross examination in routine medicolegal practice of autopsy. To find out the type of liver diseases in relation to age and sex of the studied autopsy cases from the local population. To assess and compare histopathology of liver among accidental deaths, sudden natural deaths and deaths due to poisonings. To compare results of this study with other studies. Suggestion of authenticity of diagnosis from the histopathology findings of liver. Material and MethodsThis observational cross section study will be carried out in the department of forensic medicine and toxicology on 100 cases in JLN Medical college and attached hospitals with cooperation from the department of pathology after obtaining due permission from the institutional ethical committee. Conclusionhepatic lesion can present in various forms at autopsy. Non-neoplastic Lesions should be given equal importance as neoplastic. An enlarged liver does not always indicate malignancy. There are many clinical conditions in which liver are affected as secondary phenomenon. Gross and histo-morphological examination of the tissue can diagnose the liver lesions with great accuracy and is beneficial for patient’s further survival, in setups where facilities to perform liver biopsies are available. Liver should be investigated as a part of routine autopsy procedure in all post-mortem cases. Keywords— Liver, neoplastic, Histo morphological.

A Case of Using No-Touch Saphenous Vein Graft in Redo CABG after Multiple Failed Percutaneous Coronary Interventions

The modality of repeat revascularization due to late graft failure is a debated topic. The latest available European guidelines recommend redo coronary artery bypass graft (CABG) for cases of extensively diseased and/or occluded grafts and those with diffuse native vessel disease. We present the case of a patient being relieved of recurrent unstable angina pectoris with redo CABG using no-touch saphenous vein grafts after repeated and unsuccessful attempts with percutaneous coronary intervention (PCI). This could be an alternative to PCI in patients with a complex medical history. Teamwork between cardiologists and surgeons is pivotal in deciding the best treatment modality.
A Novel Predictive Scoring System for 90-Day Mortality among Patients with Hepatocellular Cell Carcinoma Receiving Major Hepatectomy

Simple Summary Hepatocellular carcinoma (HCC) is a major malignancy correlated with many cancer-related deaths. Surgical intervention provides superior long-term survival; however, perioperative mortality is a major concern for clinicians while making treatment decisions, especially for major hepatectomy. Scoring systems for predicting 90-day mortality in patients with HCC undergoing major hepatectomy are not available. By using the stepwise selection of the multivariate Cox proportional hazards model, we divided the patients with HCC receiving major hepatectomy into four risk groups. The Chang Gung-PohAi predictive scoring system showed significant differences in the 90-day mortality rate among the four risk groups (very low risk: 2.42%, low risk: 4.09%, intermittent risk: 17.1%, and high risk 43.6%). The Chang Gung-PohAi predictive scoring system is a promising tool for predicting 90-day perioperative mortality in patients with HCC undergoing major hepatectomy. Abstract Purpose: Hepatocellular carcinoma (HCC) is a major malignancy and the common cause of cancer-related deaths. Surgical intervention provides superior long-term survival outcomes; however, perioperative mortality is a major concern for clinicians while making treatment decisions, especially for major hepatectomy. Scoring systems for predicting 90-day mortality in patients with HCC undergoing major hepatectomy are not available. Methods: This study used the Taiwan Cancer Registry Database that is linked to the National Health Insurance Research Database to analyze data of 60,250 patients with HCC who underwent major hepatectomy and determine risk factors to establish a novel predictive scoring system. By using the stepwise selection of the multivariate Cox proportional hazards model, we divided the patients with HCC undergoing major hepatectomy into four risk groups. Results: The Chang Gung-PohAi predictive scoring system exhibited significant differences in the 90-day mortality rate among the four risk groups (very low risk: 2.42%, low risk: 4.09%, intermittent risk: 17.1%, and high risk: 43.6%). Conclusion: The Chang Gung-PohAi predictive scoring system is a promising tool for predicting 90-day perioperative mortality in patients with HCC undergoing major hepatectomy.
Effects of 4‐Oxo‐2‐nonenal on biochemical properties of bovine heart mitochondria

Abstract The effects of lipid peroxidation products 4‐Hydroxy‐2‐nonenal (4‐HNE) and 4‐oxo‐2‐nonenal (4‐ONE) were evaluated using bovine heart mitochondria. Oxygen consumption rate (OCR), ultrastructure, antioxidant activity, and membrane permeability were examined to compare their effects on isolated mitochondria from beef cardiac muscle. For the mitochondrial morphology, the final concentration of mitochondria and 4‐ONE or 4‐HNE in the reaction tube were 10 mg/ml and 1 mM, respectively. For the OCR experiment, mitochondria (2.5 mg/ml) were incubated with 0.20 mM ONE or in a Clark electrode chamber at 25°C. Mitochondrial membrane permeability was determined by incubating 0.5 mg/ml of mitochondrial protein with either 0.05 mM ONE or HNE or ethanol control at pH 5.6 and 7.4 at 25°C. Transmission electron microscopy (TEM) revealed that the size of 4‐ONE treated mitochondria at pH 7.4 increased (p < .05), as did permeability (p < .05), unlike ethanol controls. However, mitochondria incubated with 4‐ONE at pH 5.6 showed a decrease in volume (p < .05). Incubating mitochondria with 4‐ONE at pH 5.6 and pH increased oxygen consumption rate 7.4 caused less oxygen consumption than either 4‐HNE treatment or ethanol control. The hydrogen peroxide assay (H2O2), ferric reducing antioxidant properties (FRAP), and 2,2’‐azinobis (3‐ethylbenzthiazoline‐6‐sulfonic acid) (ABTS.+) assays revealed that 4‐ONE is a more potent inhibitor of the endogenous antioxidant system of mitochondria than 4‐HNE (p < .05).
Party conflict regulation and intra-party hierarchy in contemporary party organization

ABSTRACT This paper is concerned with one important dimension of intra-organizational hierarchy that has to date received only little attention in cross-national party research, although its relevance has grown in light of both the increasing empowerment of rank-and-file members and the growing inclusiveness of contemporary party organizations: the range of monitoring and disciplinary mechanisms available to parties to manage internal differences and dissent essential to assure the day-to-day functioning of complex organizations. Based on the distinction between ‘organizational control’ and ‘leadership power’ that can be exercised through these mechanisms, this paper explores how the availability and nature of such mechanisms in party statutes is shaped by differences in ideology on the party level and the legal regulation of intra-party conflict regulation on the system level. Patterns are examined with regard to state-wide parties in Germany and Spain, two countries that regulate intra-party conflict legally, and the UK and Ireland, two countries that do not.
Literature in Language Syllabus: Space and Contributions

This study explores the place of literature in language syllabus and analyzes how literature supports language enrichment, extensive reading and critical reading. Literature for language enrichment describes how literature supports the development of language skills in students. Literature for extensive reading deals with how literature supports the development of inferential and literary skills. Likewise, literature for critical reading describes how literature contributes to the development of intellectual skills in students. For this, theoretical and empirical studies have been consulted. Similarly, five teachers teaching English language/literature at university level as primary sources have been interviewed to collect data. The data collected from interviews have been discussed under four different themes. The study concludes that literature occupies an important space in language syllabus as literature is pedagogically, linguistically and aesthetically embedded. Literature in language syllabus is relevant to teach language skills, for example, listening, speaking, reading and writing. The study shows that literature provides the ground to teach literary and inferential skills: commenting, appreciating, characterizing, finding clues, developing supporting details, drawing conclusion. In addition, literature supports to teach intellectual skills: analyzing, synthesizing and interpreting using literary criticism.
Distinct metabolic profiling is correlated with bisexual flowers formation resulting from exogenous ethephon induction in melon (Cucumis melo L.)

Melon (Cucumis melo L.) is an agronomically important vegetable. Most cultivars of melon are andromonoecious and bisexual flowers only emerged from the leaf axil of lateral branches. However, the regulatory mechanism contributing to the occurrence of bisexual flowers were still obscure. In this study, ethephon was applied in two common cultivars of melon. In control without ethephon treatment, no bisexual flower was made in the main stem. However, 6.56 ± 1.42 and 6.63 ± 0.55 bisexual flowers were respectively induced in main stem of ‘Yangjiaocui-QX’ and ‘Lvbao’ after ethephon treatment, and induced bisexual flowers distributed in 12–20 nodes of main stem. During the formation of bisexual flowers, 41 metabolites were significantly up-regulated and 98 metabolites were significantly down-regulated. According to the KEGG enrichment analysis of 139 different metabolites, a total of 30 pathways were mapped and KEGG terms of “Phenylalanine, tyrosine and tryptophan biosynthesis”, “Phenylalanine metabolism” and “Flavone and flavonol biosynthesis” were significantly enriched. In three significantly enriched KEGG terms, shikimic acid, L-tryptophan, L-phenylalanine, and kaempferol were significantly up-regulated while L-tyrosine, 4-hydroxycinnami acid and luteolin were significantly down-regulated in ET compared to CK. Different metabolites were also classified depend on major class features and 14 classes were acquired. The results of metabonomics and endogenous hormone identification indicated that ethylene could enhance the concentration of salicylic acid, methyl jasmonate, ABA and IAA. This study provided an important theoretical foundation for inducing bisexual flowers in main stem and breeding new varieties of melon in future.
La cisteamina y sus aplicaciones en la producción in vitro de embriones

La producción in vitro de embriones (PIVE) es una biotecnología aplicada a diferentes especies de mamíferos domésticos y silvestres, además del humano. La PIVE comprende la maduración in vitro de ovocitos (MIV), fecundación in vitro de ovocitos madurados (FIV) y el cultivo in vitro de ovocitos fertilizados (CIV). En los procesos de la MIV y CIV se tiene un incremento de los niveles de especies reactivas del oxígeno (ROS) que generan mayores niveles de estrés oxidativo, que ante junto a un deficiente sistema antioxidante en condiciones in vitro se pueden afectar estos procesos. Ante esta situación, los medios de maduración se suplementan con compuestos antioxidantes como la cisteamina (CYS) que es un amino tiol (HSCH2CH2NH) de bajo peso molecular (77.1 g/mol), tiene actividad antioxidante propia, promueve el transporte de cisteína al interior de la célula y favorece la síntesis de glutatión (GSH). Investigaciones sobre el uso de la CYS en la PIVE indican que se estimula la producción de GSH, la maduración ovocitaria y favorece el proceso de segmentación y blastulación; asimismo, tiene efectos sinérgicos con otros antioxidantes o con factores de crecimiento, de manera que el interés sobre esta molécula y sus efectos en la PIVE ha ido aumentando a través de los años. Este artículo de revisión presenta las propiedades y efectos de la cisteamina en el sistema de producción in vitro de embriones en rumiantes.
Performance Appraisal Strategies and Job Productivity of Business Studies Teachers in Public Secondary Schools in Akwa Ibom South Senatorial District

This study sought to determine the relationship between performance appraisal strategies and job productivity of Business Studies teachers in Public Secondary Schools in Akwa Ibom South Senatorial District. Three specific objectives, three research questions and three null hypotheses were formulated for the study. The correlational research design was used in this study. The population of the study comprised 63 principals and 177 Business Studies teachers; totaling 240 respondents which were drawn from 63 public secondary schools in Akwa Ibom South Senatorial District. The sample consists of 54 principals and 123 Business Studies teachers which gave a total sample size of 177 respondents and were obtained statistically using Taro Yamane formula. Simple random sampling technique was used for the study. Two research instruments captioned: “Performance Appraisal Strategies Questionnaire (PASQ)” for Business Studies teachers and “Job Productivity of Business Studies Teachers Questionnaire (JPBSTQ)” for principals were used for data collection. The instruments were face validated by three experts in the Department of Business Education, University of Uyo. Cronbach’s Alpha technique was used in determining the reliability coefficient of the instruments (PASQ) and (JPBSTQ) where coefficient indices of . 74 and . 95 were obtained respectively. Simple Linear Regression analysis was used in answering the research questions as well as testing the null hypotheses at 0.05 level of significance. The findings of the study revealed that there is a strong and significant relationship between the application of management by objectives, 360 degree feedback, and assessment centre appraisal strategy and job productivity of Business Studies teachers in Public Secondary Schools in Akwa Ibom South Senatorial District. From the findings, it was concluded that if performance appraisal strategies are properly applied by principals and board, itwould go a long way to enhancing job productivity of Business Studies teachers in Public Secondary Schools as well as promoting the students’ academic achievement. Therefore, it is recommended among others that Government through State Secondary Education Board should regularly organize seminars, workshops and conferences for principals and teachers particularly on the rudiments of performance appraisal strategies so that the application of these strategies would be handled at ease.
