Hard carbons from waste hemp via hydrothermal carbonization with mil chemical activation for sodium–ion batteries
Authors: Antoran Navarro Daniel , Alvira Darío , Manyà Joan J.
Published: July 2023

Owing to its wide availability and low cost, sodium-ion batteries (SIBs) appear as a very promising option for post-lithium energy storage systems. However, commercial graphite anodes used in lithium-ion batteries are not suitable for SIBs, due to a difficult insertion of sodium ions into the graphitic layers. Possible anode candidates focus on hard carbons (HCs). Here, HCs were synthesized from waste hemp hurd (WHH) via hydrothermal pretreatment (with either heteroatom doping or K2CO3 activation) and subsequent carbonization under Ar at 800 or 1000 °C. Regarding mild chemically activated HCs, the best material (exhibiting a 76% ICE and impressive reversible charge capacities of 354 and 77 mA h g–1 at 0.1 and 2 A g–1, respectively) was the carbon produced via hydrothermal preatretment in HCl aqueous solution and subsequently heated up to 1000 °C. However, poor cycling stability was observed for the last material, suggesting that some irreversible sodiation processes can take place.

Published: July 2023

Sesaot River is a river located in Narmada, West Lombok. The Sesaot River has been widely used by the surrounding community for their agricultural, plantation and daily activities. The high activity of the people around the river causes a decrease in the quality of river water. Macrozoobenthos is a bioindicator that can be used to describe a water's air quality. The purpose of this research is to examine the water quality of the Sesaot River utilizing macrozoobenthos as a bioindicator. The study was carried out at three different locations along the Sesaot River: upstream, middle, and downstream. At each observation site, macrozoobenthos ecological study and measurements of river water physical and chemical parameters were performed. According to observations, the pH, DO, and TDS of river water remain within the range of acceptable environmental quality standards. The macrozoobenthos found in the Sesaot Narmada river consist of 3 classes, 8 families and 8 species. Gastropoda, Mollusca, and Insecta are the third class discovered. The macrozoobenthic diversity index values discovered ranged from 0.8 to 1.35. Based on these findings, the macrozoobenthos diversity at the three locations is low. The uniformity index values obtained at the three stations ranged from 0.03 to 0.07, indicating that the distribution of individuals was unequal and unbalanced. At the three stations, the dominance index ranged from 0.27 to 0.55. Based on the findings, it is possible to conclude that the water quality of the Sesaot Narmada river is moderately to badly polluted.

Published: July 2023

Octopus fishing activities are increasingly being carried out by local fishermen making the variety of catches uncontrollable. It is feared that this diversity of catches will affect the biological condition of the octopus, which will lead to a decrease in the catch of fishermen. This study aims to: (1) determine growth patterns, body shape, age group, condition factors, spawning/maturity fit and catchability in octopus fisheries management, (2) biological dimensions of octopus fisheries management, and (3) identify attributes / lever indicators to increase the index value and sustainability status of the biological dimensions of octopus fisheries management. The results showed that the growth patterns of octopuses landed on Pandanan Beach, North Lombok Regency, were negative allometric with a b value of 2.1600. Meanwhile, octopus body shape is in the less flattened category with a condition factor (K) value of 1.85, with 2 age groups, namely the first age group with a length range of 24 cm - 48 cm and the second age group with a length range of 49 cm - 68 cm. Meanwhile, the number of octopuses worth catching was 238 which weighed > 320 grams, and 2 octopuses that were not yet fit to catch weighed < 320 grams. The sustainability status of octopus management from the biological dimension obtained a value of 52.34% with a fairly sustainable status. The attributes that need priority attention are stock enrichment and range collapse. Changes to these two attributes will affect the increase or decrease in the value of the biological dimension sustainability index.

Authors: Anjani Dewa Ayu Vania Novista
Published: July 2023

NAFLD is a highly prevalent liver disease that encompasses various clinical presentations. Initially, patients are at high risk of experiencing cardiovascular events, while some may progress to advanced fibrosis or even cirrhosis, thus increasing the risk of liver decompensation and mortality. Accurate methods of diagnosing and managing NAFLD are crucial in order to minimize the impact of the disease. Moreover, the diagnosis of NAFLD is often overlooked by doctors and only receives attention when it leads to serious complications. The purpose of this literature review is to enhance the understanding of Non-alcoholic fatty liver disease, with a focus on discussing the methods of diagnosing and managing NAFLD based on published literature references from various databases. NAFLD can be diagnosed through a comprehensive approach involving clinical laboratory findings, radiological modalities, and biopsy. The management of NAFLD includes lifestyle modifications, pharmacological interventions, and liver transplantation. Despite the availability of various diagnostic methods for NAFLD in this era, biopsy remains the gold standard. The pharmacological treatment options for NAFLD are still limited, and the cornerstone of any treatment is diet, weight loss, and physical exercise. Early diagnosis and a comprehensive management approach can be beneficial for patients with NAFLD.

The relationship between post-traumatic stress disorder symptoms, life satisfaction, and well-being comparisons: A longitudinal investigation
Authors: Schlechter Pascal , Hoppen Thole H. , Morina Nexhmedin
Published: July 2023

Objective: Many individuals who encounter potentially traumatic events go on to develop post-traumatic stress disorder (PTSD) symptoms. Research suggests that survivors of traumatic events frequently compare their current well-being to different standards. Yet, our understanding of the role of comparative thinking in well-being is limited to a few cross-sectional studies. We therefore examined the temporal relationship between aversive well-being comparisons (i.e., comparisons threatening self-motives), PTSD symptoms, and life satisfaction in individuals with a trauma history. Method: A sample of 518 participants with exposure to traumatic events was administered measures of PTSD, life satisfaction, and the Comparison Standards Scale for Well-being (CSS-W) at two timepoints, three months apart. The CSS-W assessed the frequency, perceived discrepancy, and affective impact of aversive social, temporal, counterfactual, and criteria-based comparisons related to well-being. Results: Comparison frequency emerged as significant predictor of PTSD symptoms, beyond baseline PTSD levels. Life satisfaction contributed unique variance to the comparison process by predicting comparison frequency, discrepancy, and affective impact. The findings suggest that frequent aversive comparisons may lead to a persistent focus on negative aspects of well-being, thereby exacerbating PTSD symptoms. They further indicate that comparison frequency, discrepancy, and affective impact are significantly influenced by life-satisfaction. Conclusions: Altogether, the findings support the need for a thorough examination of the role of comparative behavior in clinical populations, which may ultimately help improve clinical care.

Indonesia merupakan suatu negara agraris (pertanian) yang kaya akan hasil alamnya. Kesuburan tanahnya memungkinkan berbagai jenis tumbuhan dapat ditanam dan dilestarikan dengan baik, seperti sayur-sayuran, buah-buahan, tanam-tanaman obat maupun berbagai jenis tanaman hias. Salah satu dari jenis tanaman obat yang digunakan masyarakat adalah Ciplukan (Physallis angulata L.) family solanaceae.Metode penelitian yang dilakukan adalah metode penelitian eksperimental dengan cara mempelajari penurunan kadar gula darah pada kelinci sebelum dan setelah diberikan sediaan teh dari Ciplukan (Physallis minimu L). Berdasarkan hasil penelitian bahwa pada pemberian glukosa melalui oral maka kadar gula darah (KGD) kelinci mengalami peningkatan dari kadar gula darah ( KGD) puasa. Hal ini disebabkan bertambahnya glukosa (gula) dalam darah karena pemberian larutan glukosa. Lalu pada menit ke 30 setelah pemberian ciplukan (Physalis minima L) maka kadar gula darah (KGD) setiap kelinci mengalami penurunan karena kerja ciplukan yang menurunkan kadar gula darah. Dari hasil percobaan bahwa pemberian sediaan ciplukan (Physallis minima L) kepada kelinci ternyata dapat menurunkan kadar gula darah. Untuk itu disarankan kepad masyarakat kiranya dapat mempergunakan obat tradisional untuk menurunkan kadar gula darah. Dan kepada peneliti selanjutnya agar dapat membandingkan efek penurunan kadar gula darah dengan tanaman herbal lainnya seperti lidah buaya (Aloe vera)

Study of TiO2 on the Voltage Holdoff Capacity of Cr/Mn-Doped Al2O3 Ceramic in Vacuum
Authors: Feng Dandan , Wang Xiaojing , Zhao Shike , Song Baipeng , Zhang Guanjun
Published: July 2023

With the development of vacuum electronic devices toward high power, high frequency, and miniaturization, the voltage holdoff capacity of the insulation materials in devices has also been raised to a higher demand. Cr/Mn/Ti-doped Al2O3 ceramics were prepared, and the bulk density, micromorphology, phase composition, resistivity, secondary electron emission coefficient, and surface flashover threshold in the vacuum of the Al2O3 were characterized. The results show that the addition of TiO2 to the Al2O3 ceramic can promote the sintering of the ceramic. The Cr/Mn/Ti-doped Al2O3 ceramic with a homogeneous microstructure can be obtained by an appropriate amount of TiO2 addition. In the process of the heat treatment, the TiO2 in the ceramics was reduced to a certain degree, which had an impact on the microstructure of the Al2O3 ceramic. Adding a small amount of TiO2 can improve the voltage holdoff performance in the vacuum. The value of the surface flashover threshold in the vacuum of the Cr/Mn/Ti-doped Al2O3 ceramic containing 1 wt.% TiO2 reached a value of 33 kV, which is 32% higher than that of the basic Al2O3 ceramic. The preparation of Al2O3 ceramics with a high voltage holdoff capacity in a vacuum provides fundamental technical support for the development of vacuum electronic devices.

In the context of global competition and technological progress, an increasing number of factors influence the economies of the world. With the outbreak of the war in Ukraine, there have been dramatic changes in global investment trends. The war has repercussions far beyond its immediate surroundings, causing a cost-of-living crisis that affects billions of people around the world while rising energy and food prices depress real incomes and exacerbate debt tensions. Investor uncertainty and risk aversion could put significant pressure on FDI flow this year. The impact on investment flows to developing countries in 2022 and beyond is difficult to predict. The research aims to establish the regularity of the state of investment activity in the context of the global world crisis and to determine the features and prospects of investment activity development. This can be done by conducting a regression analysis to reflect the dependence of the impact of factors on the level of investment activity in 25 economies of the world according to the Global Outsourcing Attractiveness Index between the results of legal adaptability and corporate performance. To check the level of investment activity it is necessary to analyze the state of FDI flows by regions, economies, and countries. Research methods: method of information synthesis; regression analysis; systematization, generalization, comparative analysis. Results. It has been established that as a result of regression analysis, the value of the coefficient of determination indicates that the regression model explains 78% of the dependence of the level of investment activity in 25 economies of the world between the results of legal adaptability and corporate activity. This indicates that there are still a small number of other factors influencing the level of investment activity that is not included in the regression model. It has been determined that global FDI flows recovered to USD 972 billion in the first half of 2022. However, most of the increase was in the first quarter, while global FDI flows decreased by 22% in the second quarter of 2022 compared to the previous quarter. This was caused by rising inflation and interest rates, and rising energy prices, due to Russia’s full-scale invasion of Ukraine. The study found that FDI flows recovered significantly in all regions of the world. It was found that FDI increased sharply in some European countries after the negative inflows recorded in the second half of 2022, the latter was also driven by significant growth in Australia, Germany, Mexico, Spain, and Sweden, whose FDI inflows increased by more than USD 15 billion. It has been revealed that the United States was the leading recipient and investor of FDI worldwide in 2021.
