Lead (Pb) Reduction Efficiency in Used Lubricating Oil in Ship Using The Acid Clay Treatment Method: Perspective of Environmental Pollution Control at Paotere Port, South Sulawesi, Indonesia

The number of watercrafts in the sea will have an impact on the amount of waste lubricant oil that is discharged into the sea, which ultimately results in pollution. The increasing level of hazardous and toxic materials (B3 waste) is concerned to have a wider impact on public health and environment quality. One of the B3 wastes that requires special handling due to its high quantities is used lubricating oil. Utilization and processing of waste lubricant oil discharged from the ship is an alternative that can be applied to reach efficient consumption of petroleum which is shrinking from year to year. Therefore, we need a processing method that can reduce the pollutants generated from the waste, one of which is the Acid Clay Treatment method. This treatment aims to determine the best conditions for reducing heave metal lead (Pb) through Acid Clay Treatment method and to assess the decrease in Pb concentration contained in used lubricating oil from ship. The adsorbent used was clay that has been activated with sulphuric acid. The processing of used lubricating oil was carried out using three variations, including adsorbent concentration, contact time, and acidity (pH). The test results of used oil lubricating oil processing were 15 gram of adsorbent concentration, 90 minutes of contact time, and pH 4. The Pb reduction efficiency obtained from Acid Clay Treatment method in the best conditions was 53.72%.

“You belong in the kitchen”: social media, virtual manhood acts, and women strength sport athletes’ experiences of gender-based violence online

ABSTRACT The virtual world has transformed sport and leisure spaces, including how we communicate and interact with others globally. Despite the positives of social media, it is also a space which may facilitate hate, abuse, discrimination, and gender-based violence. In this study, women strength sport athletes’ experiences and perceptions of gender-based violence through the enactment of Virtual Manhood Acts (VMAs) are explored, using interviews with thirteen competitive women athletes. Findings reveal that VMAs are used to regulate gender norms and ideologies, promote misogyny, and endorse a hierarchical gender order. In addition, women experience appearance-related commentary and gender questioning, which arguably reduces their worth to their appearance, with expectations of conformity to the “male gaze.” Finally, VMAs are targeted towards women through accusations of steroid use and through criticism of form and technique, reinforcing strength sports as a male-domain and marginalising women’s achievements. While previous research has analysed the existence of VMAs online, in this study the importance of considering women’s perceptions of VMAs, and the wider impact they can have, is further considered.

Megawati Soekarno Putri Government Policy In Dealing With The Effects Of The Bali Bombings I In 2002

The Bali Bombing I in 2002 was one of the events caused by terrorists in Indonesia. Terror acts carried out in the Bali region with bombings killed 202 people. The incident occurred when the Indonesian government did not yet have laws and regulations governing the handling of explosions. The Bali Bombing I had a wide impact on the world of Bali tourism. The explosion destroyed the Paddy's Pub cafe, Sari Club and the United States Consulate. More than 519people were recorded, consisting of 202 people died and 317 people were outpatient. The Bali Bombing I caused many problems that had to be handled by the Megawati Soekarnoputri Government, among others, the obstacles to assistance from the central government to the Bali local government, the handling of legislation did not yet exist, limited hospital installations, reconstruction and normalization in the tourism sector had not yet been implemented. recovered for tourism promotion.

Map Of Corruption In Kudus District (Case Study Of The Corruption Of The Regent Of Kudus In 2019)

The crime of corruption is a crime that has a wide impact, in Indonesia itself there have been many cases of corruption that have occurred and it seems that it has become a culture for government officials. This study aims to create a corruption map by Muhammad Tamzil (Bupati Kudus period 2018 to 2023). This research uses a case study research method of content analysis on the Supreme Court's decision, data analysis using Nvivo12plus with data presentation in the form of graphs and tables. The results of the study revealed that the criminal acts of corruption committed by Muhammad Tamzil were in the form of gratification for the appointment of several parties and also receiving gifts from several inaugurated employees. Transactional becomes the highest action because in this case it involves many people and also the stages of the process are gradual. In every crime there is a correlation with each other, the 3 highest correlations are transactional and gratification with 0.982908 points. Transactional and bribes which have 0.949911 points, bribes and gratuities which have 0.949741 points. This research is expected to provide information to the public about what are the factors that cause corruption. The limitation of this research is that the data used is still limited to the type of secondary data, namely the Supreme Court decision document. The next research needs to use primary data, namely interview and observation data.

Recent Progress in Phase Stability and Elastic Anomalies of Group VB Transition Metals

Recently discovered phase transition and elastic anomaly of compression-induced softening and heating-induced hardening (CISHIH) in group VB transition metals at high-pressure and high-temperature (HPHT) conditions are unique and interesting among typical metals. This article reviews recent progress in the understanding of the structural and elastic properties of these important metals under HPHT conditions. Previous investigations unveiled the close connection of the remarkable structural stability and elastic anomalies to the Fermi surface nesting (FSN), Jahn–Teller effect, and electronic topological transition (ETT) in vanadium, niobium, and tantalum. We elaborate that two competing scenarios are emerging from these advancements. The first one focuses on phase transition and phase diagram, in which a soft-mode driven structural transformation of BCC→RH1→RH2→BCC under compression and an RH→BCC reverse transition under heating in vanadium were established by experiments and theories. Similar phase transitions in niobium and tantalum were also proposed. The concomitant elastic anomalies were considered to be due to the phase transition. However, we also showed that there exist some experimental and theoretical facts that are incompatible with this scenario. A second scenario is required to accomplish a physically consistent interpretation. In this alternative scenario, the electronic structure and associated elastic anomaly are fundamental, whereas phase transition is just an outcome of the mechanical instability. We note that this second scenario is promising to reconcile all known discrepancies but caution that the phase transition in group VB metals is elusive and is still an open question. A general consensus on the relationship between the possible phase transitions and the mechanical elasticity (especially the resultant CISHIH dual anomaly, which has a much wider impact), is still unreached.

Navigating Loss of Abortion Services—A Large Academic Medical Center Prepares for the Overturn of Roe v. Wade

(Abstracted from N Engl J Med 2022;386:2061–2064) As abortion is now intensely politicized in the United States, public discourse obscures its nature as an issue of health and health care. Preparation for the wide impact of criminalized abortion is paramount.

Decolonizing Renaissance Humanism

Abstract This article traces the origins of the Eurocentric vision of Renaissance humanism and shows that in fact the revival of letters in thirteenth-century Italy had a much wider impact than traditionally thought. This “decolonized” vision of Renaissance humanism is centered on three trends: imperial humanism (humanist ideas of empire, both within and beyond the metropole), Indo-humanism (syncretic humanisms, especially in Asia and the Americas), and post-humanism (the movement’s long shadow into the eighteenth century). When placed in this new light, Renaissance humanism emerges as neither purely graciously cosmopolitan and proto-liberal, nor chauvinistically imperialist and statist, although it was very frequently embedded in imperial and evangelization projects. Rather, at a fundamental level it represented a toolbox of ideas and scholarly techniques that could be put to differing ends depending on the circumstances, while retaining certain common features that endured well into the age of “Enlightenment.” In making its argument about the past, present, and future of the scholarship on Renaissance humanism, this article also relies on a large corpus of little-known texts in various languages by a host of non- and extra-European humanists

The Urgency of Guarantee Off Takers in Increasing Investment Oil and Gas Mining

The investment climate for oil and gas mining since 2000 has continued to decline until now. This can be attributed to various factors, one of which is the lack of certainty regarding buyers of oil and gas at the downstream stage. This will certainly have an impact on the development of oil and gas mining, so that it can have a wider impact on welfare aspects. This study will discuss the urgency and reasons for the inclusion of a guarantee off taker as one of the clauses in an oil and gas contract. This study uses a normative method with a statutory and conceptual approach. This study found that there are at least 3 dimensions of urgency and reasons for the inclusion of an off takers guarantee clause, namely the dimension of people's livelihood based on Article 33 paragraph (3) of the 1945 Constitution which mandates efforts for people's welfare because through large investments people's welfare should also increase. Next is the dimension of the oil and gas business which has a high risk that requires certainty in selling oil and natural gas. The last dimension is the investment dimension.

Relating protein crystal structure to ligand-binding thermodynamics.

An important interface between biophysical chemistry and biological crystal structures involves whether it is possible to relate experimental calorimetry measurements of protein ligand binding to 3D structures. This has proved to be challenging. The probes of the structure of matter, namely X-rays, neutrons and electrons, have challenges of one type or another in their use. This article focuses on saccharide binding to lectins as a theme, yet after 25 years or so it is still a work in progress to connect 3D structure to binding energies. Whilst this study involved one type of protein (lectins) and one class of ligand (monosaccharides), i.e. it was specific, it was of general importance, as measured for instance by its wide impact. The impetus for writing this update now, as a Scientific Comment, is that a breakthrough in neutron crystal structure determinations of saccharide-bound lectins has been achieved. It is suggested here that this new research from neutron protein crystallography could improve, i.e. reduce, the errors in the estimated binding energies.

Illuminating traces of an Achaemenid's monumental complex in the Southern Caucasus by electrical resistivity tomography

The Achaemenid Empire controlled the Western Asian landmass between ca. 550–300 BCE. By some estimates, its subject peoples made up almost 44% of the world population. In recent years, studies have moved from a consideration of its core region, located in the province of Fars, Iran, to the investigation of imperial rule in the dependent regions. Since Achaemenid centers were often built of mudbrick and thus not easy to recognize by traditional archaeological methods, geophysical methods play an important role in this research. This paper reports the results of an innovative Electrical Resistivity Tomography (ERT) study undertaken at one such center, Saaklemo, in the Kakheti Province, Republic of Georgia and shows the wide impact of the geophysical methods in the detection of the archaeological sites.In three areas of this ancient site between 2020 and 2021, following archaeological survey and magnetometer prospection, several three-dimensional (3D) ERT measurements, composed of dense parallel two-dimensional (2D) tomographies with dipole-dipole configuration, were carried out. To reconstruct the resistivity distribution of the subsurface, we used the smoothness-constrained inversion method, especially as the substructure was made of mudbrick and thus resistivity values of these anomalies were close to the background anomaly. Therefore, with smoothness-constrained inversion, we could detect the slight resistivity differences, which were partly due to density differences, and hence this method was capable of detecting these anomalies.In area 1, for the first time with ERT method, we were successful in discovering an extensive mudbrick (partly burnt) substructure at a depth of 40 cm to 1 m. After analyzing the magnetic data and a 3D model of this substructure based on the ERT data, a large excavation was conducted and a mudbrick substructure with six in-situ bell-shaped column bases was unearthed, which was destroyed by conflagration. The size and the architectural techniques used for this building prove that this excavated structure was an administrative building and served for representative purposes. Further presumed mudbrick structures were detected in the other two areas with the ERT method, but they have not yet been excavated.

Electron exchange capacities of colloidal biochar: Affected by spatial structure distribution instead of particle size

Electron exchange capacities (EEC) of biochar have a wide impact on the environmental electron transfer processes. However, during the application, the gradual disintegration and aging will lead to the structure of the residual biochar after producing micro/nanosized biochar being different from the fine particles. It is questionable how the persistently produced micro/nanosized biochar and the residual biochar will perform especially in the EEC aspect. Herein, bulk biochar (<75 μm) was water-exfoliated repeatedly by ultrasonication of gradient intensity. The structure and functional groups as well as EEC of multi-exfoliated biochar (<1 μm) and the pristine/residual biochar were characterized. It turned out that the EEC of exfoliated biochar was influenced by spatial structure distribution instead of particle size. Colloidal starch-char expressed descending EEC while colloidal pine-char was reverse with increasing times of exfoliation, resulting from the different distribution of oxygenated functional groups in the bulk biochar particles. This distribution was ascribed to different pyrolysis mechanisms of starch (decomposition and condensation) and wood (unreacted-core-shrinking approximation). The findings can provide insights into long-term effects of EEC caused by biochar fragments physically degraded from bulk biochar during applications.

Research on the Application of VR/AR Interactive Design Technology in the Field of Public Security

Disease, earthquake, fire, stampede, malignant injury and so on. In all kinds of sudden events, the design of public emergency rescue facilities is more and more important. Public emergency refers to an emergency that occurs suddenly, causes or may cause heavy casualties, property losses, ecological environment damage and serious social harm, and endangers public security, which is characterized by abruptness, severity and wide impact. The occurrence of these incidents will destroy the normal social operation mechanism and the normal social order, cause a huge social psychological crisis, hinder social stability and development.

How Implementing of Social Capital to Improving Islamic Education Quality: The Social Evolution Model

Social change is a phenomenon that often occurs in life that demands improvement and creates shared prosperity to strengthen social capital as a component involved in it. The low average formal education in Indonesia is still low in Southeast Asia, which gives the impression that most Muslims do not have adequate quality education because there are still many people who are socially marginalized. The number of graduates of Islamic education itself is low. They make men more dignified by utilizing resources to create new things and have a wider impact. Islam has described social capital and social change in life as necessary to create a more dynamic value of life. This study is to find out how social capital is implemented by social capital to improve the quality of education with a social evolution approach. The method uses qualitative research using a grounded theory approach and analytical design thinking. The results show that come contents of social capital as a component of change that can improve the quality of Islamic education, including trust, networks, norms, and leadership, which are built on six models of social evolution, namely empathy, exploration, elaboration, exposure, and execution and expansion. The social evolution model built on design thinking can formulate efforts to improve the quality of Islamic education through strengthening the social capital formed. Research implies that improving Islamic education can be adapted to social changes in social modal, specifically in the human resources index.&#x0D;

‘People Here Are Their Own Gods’: The Migration of South African Social Workers to England

Abstract The migration of social workers has become an established trend internationally. Existing research largely ignored the impact of culture on this migration. The study presented here focused on the experiences of social workers who were trained in South Africa and migrated to England. South African-trained social workers had to adjust to significant cultural differences, ranging from the place of religion, the characteristics of the family and parenting, forms of interpersonal communication and what is considered polite and impolite behaviour. Whilst these issues have a wide societal impact, they also shape the daily reality of practising social workers. Implications for practice are discussed, and pre-migration education about the host country’s structures, a systemic induction process, mentorship and supervision with an emphasis on culture, is recommended.

The Power of Collaborative Public Scholarship

Work conducted by the Colorado Coalfield War Archaeology Project and Ludlow Centennial Commemoration Commission offers a longitudinal example of the power of collaborative public scholarship. After defining collaborative public archaeology, the article discusses issues around identifying descendant communities and other stakeholders, building and maintaining relationships, and the political nature of public archaeology and stewardship. While the collaborative experiences described here were unique, the lessons are widely applicable. The goal in sharing these lessons is to illustrate the importance of maintaining relationships with descendant communities after the completion of a project and exemplify the wide impact of well-designed collaborative public archaeology.

The 2022 extreme drought in the Yangtze River Basin: Characteristics, causes and response strategies

AbstractAn extreme drought occurred in the Yangtze River Basin in 2022, inflicting huge impacts nationwide. To provide a reference for drought prevention and mitigation, this paper presents a comprehensive analysis of the drought in the Yangtze River Basin in terms of its characteristics, causes, impacts, and response strategies. It concludes that this extreme drought stood out by its long duration, wide impact range, and severe intensity, as a combined result of abnormal high‐temperature weather and massive social water consumption. Serious impacts are observed in various fields of the economy, including agricultural irrigation, urban and rural water supply, power generation, and navigation. Finally, drought mitigation measures and effects are examined, and future drought response and mitigation strategies are proposed.

Sensitivity and spectral control of network lasers

Recently, random lasing in complex networks has shown efficient lasing over more than 50 localised modes, promoted by multiple scattering over the underlying graph. If controlled, these network lasers can lead to fast-switching multifunctional light sources with synthesised spectrum. Here, we observe both in experiment and theory high sensitivity of the network laser spectrum to the spatial shape of the pump profile, with some modes for example increasing in intensity by 280% when switching off 7% of the pump beam. We solve the nonlinear equations within the steady state ab-initio laser theory (SALT) approximation over a graph and we show selective lasing of around 90% of the strongest intensity modes, effectively programming the spectrum of the lasing networks. In our experiments with polymer networks, this high sensitivity enables control of the lasing spectrum through non-uniform pump patterns. We propose the underlying complexity of the network modes as the key element behind efficient spectral control opening the way for the development of optical devices with wide impact for on-chip photonics for communication, sensing, and computation.

Impact of ENSO Events on Droughts in China

The El Niño Southe58rn Oscillation (ENSO) is a typical oscillation affecting climate change, and its stable periodicity, long-lasting effect, and predictable characteristics have become important indicators for regional climate prediction. In this study, we analyze the Standardized Precipitation Evapotranspiration Index (SPEI), the Niño3.4 index, the Southern Oscillation Index (SOI), and the Multivariate ENSO Index (MEI). Additionally, we explore the spatial and temporal distribution of the correlation coefficients between ENSO and SPEI and the time lag between ENSO events of varying intensities and droughts. The results reveal that the use of Nino3.4, MEI, and SOI produces differences in the occurrence time, end time, and intensity of ENSO events. Nino3.4 and MEI produce similar results for identifying ENSO events, and the Nino3.4 index accurately identifies and describes ENSO events with higher reliability. In China, the drought-sensitive areas vulnerable to ENSO events include southern China, the Jiangnan region, the middle and lower reaches of the Yangtze River, and the arid and semi-arid areas of northwestern China. Droughts in these areas correlate significantly with meteorological drought, and time-series correlations between ENSO events and droughts are significantly stronger in regions close to the ocean. Drought occurrence lags ENSO events: when using the Niño3.4 index to identify ENSO, droughts lag the strongest and weakest El Niño events by 0–12 months. However, when using the MEI as a criterion for ENSO, droughts lag the strongest and weakest El Niño events by 0–7 months. The time lag between the strongest ENSO event and drought is shorter than that for the weakest ENSO event, and droughts have a wider impact. The results of this study can provide a climate-change-compatible basis for drought monitoring and prediction.
