Published: June 2024

Background

The location and type of a tumor influence the prognosis of lung cancer. Primary Central Lung Tumors (PCLTs) are correlated with poor prognoses and certain histologic types. This study aimed to present a comprehensive exploration of clinical and bronchoscopic assessments for diagnosing the histopathology types of PCLTs and identified the factors associated with certain histologic types.

Methods

This was an observational cross-sectional study of PCLTs, defined as tumors in direct contact with hilar structures or located within the inner two-thirds of the hemithorax. We gathered demographic and clinical data, as well as data on bronchoscopy assessment and histopathology type. Tumor stage, symptoms of superior vena cava syndrome, and enlargement of lymph nodes in the paratracheal and subcarinal regions were also documented.

Results

Of the 895 patients, 37.87% had primary lung tumors, with 17.76% classified as PCLTs. Notably, PCLT cases exhibited a higher proportion of stage III (28.9% vs. 18.3%; p = 0.03) and Squamous Cell Carcinoma (SCC) histopathology (37.1% vs. 17.2%; p = 0.00) compared with non-PCLT cases. Bronchoscopic findings in PCLTs revealed a predilection for central airway masses (25.2%) and compressive distal airway stenosis (25.2%). Subgroup analysis of 159 PCLT cases identified 37.10% as SCC. Multivariate analysis underscored that intraluminal masses predict central SCC (odds ratio 2.075, 95% confidence interval 1.07–3.99; p = 0.028).

Conclusion

The proportion of stage III, SCC histopathological type, and intraluminal lesions was higher in patients with PCLT than in non-PCLT cases. The presence of intraluminal lesions can predict the histopathological type of SCC in patients with PCLTs.

Authors: Almarzouki Nawaf K. , Kurdi Ayah M. , Aladni Ibrahim S. , Taha Mohammed A.
Published: June 2024

Background

The Retinal Nerve Fiber Layer (RNFL) is crucial for diagnosing and monitoring optic nerve disease and physiological thinning. Optical Coherence Tomography (OCT) is an imaging technique that provides real-time scans. This procedure is used for measuring RNFL thickness and macular thickness in chorioretinal pathologies.

Objective

This study aimed to determine RNFL thickness in healthy individuals across different age groups using OCT scans.

Methods

A retrospective cross-sectional study was conducted at King Abdulaziz University Hospital in Jeddah, Saudi Arabia. The medical records of 257 patients from the clinic specialized in glaucoma were reviewed between October 2022 and October 2023. The analyzed variables included age, gender, and RNFL thickness.

Results

The study included participants aged 18 to 84 years, with an average age of 48.11 years. Females comprised the majority (59.1%) of the subjects compared to males (40.9%). The results indicated a significant association between age and RNFL thickness in various eye regions. Specifically, the superior, inferior, and temporal areas decreased in thickness with advancing age, particularly after 40. The most pronounced age-related changes were observed in the superior and inferior regions. Furthermore, females displayed a thicker RNFL in their right eye than males. The temporal and nasal regions showed a negative correlation with age, indicating a gradual but still noteworthy reduction in thickness in these areas.

Conclusion

This study aimed to establish a normative database contributing to the increase in quality of care in ophthalmology in Jeddah, Saudi Arabia, providing valuable guidance in diagnosing, managing, and researching glaucoma, ultimately improving patient outcomes in the region.

Published: June 2024

Background

Early identification and accurate prognostication of acute ischemic stroke are crucial due to the narrow time frame for treatment and potential complications associated with thrombolysis intervention.

Objectives

This pilot study in the Southeast Asian region using Indonesian data, aims to develop a novel machine learning model for predicting the clinical outcome of acute ischemic stroke patients following thrombolysis. The model seeks to aid clinicians in identifying eligible candidates for thrombolysis therapy.

Methods

This retrospective study at Cipto Mangunkusumo Hospital’s medical records from 2014 to 2023 used non-contrast brain CT, clinical, and lab data to develop a Random Forest (RF) algorithm predicting Δ NIHSS (National Institutes of Health Stroke Scale) score, indicating functional outcome. The developed RF model was applied to a validation dataset, with performance evaluated. The study also compared RF with a previous Convolutional Neural Networks (CNN) algorithm.

Results

This study included 145 acute ischemic stroke patients treated with thrombolysis. It demonstrated the promising feasibility of using machine learning algorithms to predict clinical outcomes in this population. Integration of CT, clinical, and laboratory data as inputs to the RF models shows the best prediction performance (Accuracy = 0.75, AUC = 0.72, F1=0.50, Precision=0.60, Sensitivity=0.43, Specificity=0.88)

Conclusions

The application of machine learning shows the potential to enhance the selection process for thrombolysis intervention in treating acute ischemic stroke. Further research with larger multicenter datasets and additional imaging modalities is required to improve predictive ability.

Authors: Kundarti Finta Isti , Kiswati Kiswati , Komalyna I Nengah Tanu , Riyadi Bastianus Doddy
Published: June 2024

Background

Cases of hypertension in menopause have doubled since 1990 worldwide. During menopause, endothelial cells are destroyed due to estrogen depletion. Endothelial damage further triggers plaque in the blood while stimulating blood pressure to rise. In this case, the anthocyanin content in Hibiscus sabdariffa is an effective vasodilator of smooth muscle and blood vessels to lower blood pressure.

Purpose

This research aimed to know the effect of rosella (Hibiscus sabdariffa) on blood pressure in menopausal women with hypertension.

Methods

Quasi-experiment with pretest-posttest control group design was conducted. Ninety participants were divided into two groups, namely intervention group (45 participants) and control group (45 participants), selected from a public health center, using simple random sampling. The intervention group was given standard care and rosella extract as much as 1 x 1 with a dose of 500 mg for five days, while the control group only received standard care.

Results

Based on the paired Sample T-Test results in the experimental group, both systole and diastole pressures showed the same significant results with p-value of 0.000. Meanwhile, in the control group, the results showed a systole p-value of 0.279 and a diastole p-value of 0.132. Furthermore, the difference in posttest systole and diastole in the intervention and control groups is p-value 0.000.

Conclusion

The provision of roselle (Hibiscus sabdariffa) can reduce blood pressure in menopausal women who experience hypertension. This study is expected to help health workers provide rosella extract to menopausal women who experience hypertension as an alternative treatment.
AR/VR Virtualisation of In-Class Academic Activities
Authors: Mayank Patel Mayank Patel , Bhatt Monika , Patel Ankush
Published: June 2024

The Fourth Industrial Revolution, 4IR, or Industry 4.0, conceptualizes rapid
changes in technology, industries, and social patterns and processes in the 21st century
due to increasing interconnectedness and smart automation. This phase of industrial
change is a fusion of technologies such as artificial intelligence, gene editing, virtual
reality, and advanced robotics that are blurring the lines between the physical, digital,
and biological worlds. In the future, the most in-demand skills will not only be related
to technology but there will be a huge demand for creativity, emotional intelligence,
critical thinking, and interpersonal skills. Traditional formal education systems can no
longer respond to the most important expectations of smart cities and related societies.
Students can no longer be prepared for the future with linear knowledge-based
education, much less to compete with robots. Virtual reality has been around for over
half a century. We further present and compare a large number of recent virtual reality
technologies and discuss their potential to overcome several challenges identified in
our analyses, including cost, user experience, and interactivity. If we implement
virtualization in classroom activities, then it enhances the learning ability of students.
The human brain, as we now know, retains information more effectively when it sees,
hears, and visualizes it in its entirety as opposed to just reading it. So, by implementing
V.R. in the education sector, we will try to provide visualized practical learning
simultaneously with theoretical knowledge. Students are more engaged in their studies
when they visualize the academic material, and this will benefit society by producing
valuable human resources.

A Political Ecology of Modernist Resistance: Turning the Tide on Ecomodernism and Ecofascism in the New Climatic Regime
Authors: Julien Christopher Felix
Published: June 2024

The mounting pressures of the climate -and ecological crisis organising politics under a “new climatic regime” (Latour 2017, 3). The epistemic and affective interference of Holocene collapse (author 2022) mobilises Minority-world liberal and far-right resistance, driving feedbacks that undercut democratic capacities for mitigation and adaptation (IPCC 2022). This paper proposes approaching such resistance through an “ecology of practices” (Stengers 2005, 2010), thereby delineating a shared modern timespace linked to affordances of whiteness. In response, the paper proposes a ‘politics of life’ that displaces humanistic agency as the bearer of historical progress and territorial integrity.
Thinking with Cormac McCarthy
Authors: Pickford Henry
Published: June 2024

This brief essay honor the recently deceased American author Cormac McCarthy by interpreting a short scene from one of his screenplays as a modern instance of genuinely tragic understanding. This interpretation is compared on the one hand with a related yet comedic version of tragic knowledge, and on the other hand with the play "Oedipus the King" by Sophocles. The essay argues that fostering the presentiment of such tragic understanding might be a an effective way of motivating people to act to avert climate change.

Published: June 2024

Background

SARS-CoV-2 variants of concern (VOCs) emerged and rapidly replaced the original strain worldwide. The increased transmissibility of these new variants led to increases in infections, hospitalizations, and mortality. However, there is a scarcity of retrospective investigations examining the severity of all the main VOCs in presence of key public health measures and within various social determinants of health (SDOHs).

Objective

This study aims to provide a retrospective assessment of the clinical severity of COVID-19 VOCs in the context of heterogenous SDOHs and vaccination rollout.

Methods

We used a population-based retrospective cohort design with data from the British Columbia COVID-19 Cohort, a linked provincial surveillance platform. To assess the relative severity (hospitalizations, intensive care unit [ICU] admissions, and deaths) of Gamma, Delta, and Omicron infections during 2021 relative to Alpha, we used inverse probability treatment weighted Cox proportional hazard modeling. We also conducted a subanalysis among unvaccinated individuals, as assessed severity differed across VOCs and SDOHs.

Results

We included 91,964 individuals infected with a SARS-CoV-2 VOC (Alpha: n=20,487, 22.28%; Gamma: n=15,223, 16.55%; Delta: n=49,161, 53.46%; and Omicron: n=7093, 7.71%). Delta was associated with the most severe disease in terms of hospitalization, ICU admissions, and deaths (hospitalization: adjusted hazard ratio [aHR] 2.00, 95% CI 1.92-2.08; ICU: aHR 2.05, 95% CI 1.91-2.20; death: aHR 3.70, 95% CI 3.23-4.25 relative to Alpha), followed generally by Gamma and then Omicron and Alpha. The relative severity by VOC remained similar in the unvaccinated individual subanalysis, although the proportion of individuals infected with Delta and Omicron who were hospitalized was 2 times higher in those unvaccinated than in those fully vaccinated. Regarding SDOHs, the proportion of hospitalized individuals was higher in areas with lower income across all VOCs, whereas among Alpha and Gamma infections, 2 VOCs that cocirculated, differential distributions of hospitalizations were found among racially minoritized groups.

Conclusions

Our study provides robust severity estimates for all VOCs during the COVID-19 pandemic in British Columbia, Canada. Relative to Alpha, we found Delta to be the most severe, followed by Gamma and Omicron. This study highlights the importance of targeted testing and sequencing to ensure timely detection and accurate estimation of severity in emerging variants. It further sheds light on the importance of vaccination coverage and SDOHs in the context of pandemic preparedness to support the prioritization of allocation for resource-constrained or minoritized groups.
Virtual Clinic Telehealth Abortion Services in the United States One Year After Dobbs: Landscape Review
Authors: Koenig Leah R , Ko Jennifer , Upadhyay Ushma D
Published: June 2024

Background

Telehealth abortion has taken on a vital role in maintaining abortion access since the Dobbs v. Jackson Women’s Health Organization Supreme Court decision. However, little remains known about the landscape of new telehealth-only virtual clinic abortion providers that have expanded since telehealth abortion first became widely available in the United States in 2021.

Objective

This study aimed to (1) document the landscape of telehealth-only virtual clinic abortion care in the United States, (2) describe changes in the presence of virtual clinic abortion services between September 2022, following the Dobbs decision, and June 2023, and (3) identify structural factors that may perpetuate inequities in access to virtual clinic abortion care.

Methods

We conducted a repeated cross-sectional study by reviewing web search results and abortion directories to identify virtual abortion clinics in September 2022 and June 2023 and described changes in the presence of virtual clinics between these 2 periods. In June 2023, we also described each virtual clinic’s policies, including states served, costs, patient age limits, insurance acceptance, financial assistance available, and gestational limits.

Results

We documented 11 virtual clinics providing telehealth abortion care in 26 states and Washington DC in September 2022. By June 2023, 20 virtual clinics were providing services in 27 states and Washington DC. Most (n=16) offered care to minors, 8 provided care until 10 weeks of pregnancy, and median costs were US $259. In addition, 2 accepted private insurance and 1 accepted Medicaid, within a limited number of states. Most (n=16) had some form of financial assistance available.

Conclusions

Virtual clinic abortion providers have proliferated since the Dobbs decision. We documented inequities in the availability of telehealth abortion care from virtual clinics, including age restrictions that exclude minors, gestational limits for care, and limited insurance and Medicaid acceptance. Notably, virtual clinic abortion care was not permitted in 11 states where in-person abortion is available.
How TikTok Influencers Disclose Food and Beverage Brand Partnerships: Descriptive Study (Preprint)
Authors: Dupuis Roxanne , Musicus Aviva A , Edghill Brittany , Keteku Emma , Bragg Marie A
Published: June 2024

BACKGROUND

Food and beverage marketing is an important influence on the health and diets of adolescents. Food and beverage companies spend billions of dollars annually on advertisements to promote their products and are increasingly focusing on social media influencers. Influencer product endorsements blur the line between entertainment and marketing.

OBJECTIVE

This study aimed to quantify how often TikTok influencers promote products from food and beverage brands and document the range of ways they disclose brand relationships in their content.

METHODS

We collected up to 100 videos posted on or before July 1, 2022, from each of the top 100 influencers on TikTok in the United States and recorded information about the influencer (eg, number of followers) and video (eg, number of views and likes). For each video that contained food or beverage products, we identified the main product featured. A team of research assistants then coded each video for how the product was featured (ie, in the video, audio, or caption) and, for branded products, whether the video was accompanied by any disclosures of brand relationships. Average pairwise percentage agreement among coders was 92%, and average pairwise Cohen κ was 0.82.

RESULTS

Among the 8871 videos from 97 influencers that made up the final analytical sample, we identified 1360 videos (15.3%) that featured at least one food or beverage product. These 1360 videos were viewed >9 million times and received >1 million likes each. Nearly half (n=648, 47.6%) of the videos featured a branded product. Most videos featuring a branded product did not contain a brand relationship disclosure (n=449, 69.3%). Among videos that disclosed a brand relationship, influencers used 10 different types of disclosures. Tagging a brand in the video’s caption was the most common disclosure method (n=182, 28.1%). Six types of caption hashtags were used to disclose brand relationships, including #[brandname] (n=63, 9.7%) and #ad (n=30, 4.6%). Only 1 video (0.2%) made use of TikTok’s official disclosure label and only 1 video (0.2%) verbally mentioned a contractual agreement with a brand.

CONCLUSIONS

Among the food and beverage videos with disclosures we identified, the most frequently used mechanism—tagging the brand—did not clearly differentiate between sponsored content and the influencer trying to attract a brand or followers who may like that brand. Social media users, particularly adolescents, need clearer, more robust disclosures from influencers to protect against the undue influence of food marketing. These findings may also inform calls for the Children’s Food and Beverage Advertising Initiative—the largest self-regulatory pledge to reduce unhealthy food marketing—to include older adolescents, who are heavily targeted by food and beverage companies on social media.

Casas mayas en Mérida, Yucatán
Authors: Ferreira Marcos H. B. , Rubin de Rubin Julio Cezar
Published: June 2024

La casa vernácula maya es un elemento importante en el paisaje de la península de Yucatán, especialmente en los pueblos, aunque no sólo en éstos. Su arquitectura se adapta muy bien a las características ambientales de la región, de manera particular a las altas temperaturas, y además demostró ser resistente a los huracanes que azotaron la región en varias ocasiones. A pesar de sus diversas cualidades, la casa maya fue y sigue siendo objeto de estigma, debido al racismo que existe con relación a los mayas en Yucatán y sus prácticas sociales, incluida la vivienda. Esto ha llevado a muchas personas a demoler sus casas vernáculas, reemplazándolas por construcciones de bloques, mucho menos adaptadas a las características ambientales de la península. Algunas casas mayas, sin embargo, resisten valientemente, incluso dentro del espacio urbano de una gran ciudad como Mérida, la capital del estado de Yucatán, aportando importantes pistas sobre las transformaciones en el espacio de la ciudad y cómo afectaron a la población maya residente en Mérida, pero también, en qué medida inciden las memorias y las prácticas habitacionales en la cuestión de la identidad étnica en un contexto urbano.

Design of a Bus Communication Architecture using AXI Protocol based SoC Systems
Authors: Bhoi Bandan Kumar
Published: June 2024

Abstract: The main objective of this project is to develop and implement a bus monitor that will allow system-on-a-chip (SoC) systems that employ the Advanced EXtensible Interface (AXI) protocol to have their performance monitored. Modern SoC architectures commonly employ the AXI protocol, which offers high-performance and effective communication between master and slave devices, to connect components. The bus monitor’s real-time collection and analysis of AXI bus transactions allows for thorough performance analysis and SoC system debugging. Understanding transaction-level behaviour, spotting bottlenecks, and evaluating the overall effectiveness of the system are important goals. Verilog HDL will be used to implement the suggested bus monitor, which will then be incorporated into an FPGA-based development platform. To record transaction data, including read and write operations, addressing information, data transfers, and other metadata, it will interface with the AXI connection. A user-friendly interface will be used to process and display the collected data in order to provide a thorough performance analysis. With the creation of a specialised bus monitor for AXI-based SoC systems, this project hopes to enhance performance for a range of uses, such as networking, digital signal processing, embedded systems, and digital signal processing. The final product will be an invaluable tool for researchers, software engineers, and system designers working on intricate SoC designs that make use of the AXI protocol.

Essential oils are oils whose components are generally volatile and are obtained from various types of plants and are the largest demand commodity in marketing circles. One of the essential oil-producing plants, namely lime (C. aurantifolia) and kaffir lime (C. hystrix) so that they are widely used by industry as raw materials for making medicines, cosmetics, and perfumes because they contain various components in them. However, the community only uses the fruit as a spice for cooking and drinks, while the skin is thrown away so that it becomes waste. This study aims to determine the effect of the height of the growing location on the essential oil components of the fruit peels of C. aurantifolia and C. hystrix as measured using GC-MS. The sampling method was carried out by simple random sampling, which was taken from several trees randomly at an altitude range of 0-100, 400-500, and 1,200-1,300 masl. The extraction method used is steam-water distillation at 100°C for 6 hours. The results of GC-MS identification showed that the essential oil from the skin of C. aurantifolia fruit contains 3 main components, namely dl-Limonene, 2-β-Pinene, and γ-Terpinene and the highest component is obtained at an altitude range of 400-500 masl. Meanwhile, C. hystrix contains 5 main components in the form of 2-β-Pinene, Sabinene, dl-Limonene, Citronella, and β-Citronellol and the highest component is obtained at an altitude range of 0-100 masl. GC-MS analysis showed that the volatile oil components of the fruit peels of C. auratifolia and C. hystrix were affected by the altitude of the growing location including temperature and humidity.

Interactive model of government websites based on decision tree analysis and web quality 4.0
Authors: Rokhman Ali , Çömez Pinar , Rosyadi Slamet
Published: June 2024

Government websites are important for providing citizens access to vital public information. However, many government websites are not well-designed, difficult to navigate, even out-of-date, and insufficient in providing information and interactive channels. Based on previous studies, website development often fails because it is oriented toward implementing a mandate without evaluating the website traffic and visitors. The evaluation process of e-government websites is essential for developing the performance and quality of the websites (Lee-Geiller & Lee, 2019). This study aims to evaluate the quality of Indonesian local governments. This study used a quantitative approach with a web quality 4.0 (WebQual 4.0) instrument for assessing the quality of websites. WebQual 4.0 consists of three components: usability design, information quality, and interaction services. Data were analyzed using decision tree techniques. The main finding of the study is that not all WebQual 4.0 components affect the number of visitors. The interaction service component is the most influential factor. The results suggest a website paradigm that focuses on visitors’ interaction. Visitors should feel they are well-served and engaged when using a website. This approach of interactive websites can employ popular social media platforms to offer real-time visitor interaction.
Multiple effects of L-leucine in Escherichia coli lead to L-leucine sensitive growth in the absence of dephospho-PtsN
Authors: Kumar Neeraj , Sardesai Abhijit
Published: June 2024

In E. coli K-12, absence of dephospho-PtsN, is thought to cause
an L-leucine sensitive growth phenotype (Leu) by
hyperactivated K uptake mediated impairment of the
expression of the ilvBN operon, encoding subunits of the L-valine
(Val) sensitive acetohyrodxyacid synthase I (AHAS I), that renders
residual AHAS activity susceptible to inhibition by Leu and
K.  This is thought to lead to AHAS insufficiency and
a requirement for isoleucine (Ile). Herein we provide an alternate
mechanism for Leu of the ∆ptsN mutant. Genetic
and physiological studies with suppressors of the
Leu, indicate that impaired expression of the
ilvBN operon jointly caused by the absence of dephospho-PtsN and
the presence of Leu coupled to Leu mediated repression of expression of
AHAS III leads to AHAS insufficiency rendering residual AHAS activity
susceptible to chronic Val stress that may be generated by exogenous
Leu. Hyperactivated K uptake and an elevated
α-ketobutyrate level, mediate elevation of ilvBN expression, and
alleviate the Leu. The requirement of dephospho-PtsN
as a positive regulator of ilvBN expression, may buffer Ile
biosynthesis against Leu mediated AHAS insufficiency and protect AHAS I
function from chronic endogenous Val generated by Leu and could be
realised in certain environments that impair AHAS function.
Impact of Combined Spinal Epidural Analgesia on Biomolecular Mediators in Painless Labor: Insights from an Experimental Study in Indonesia
Authors: Agnesha Fahmi , Solikhah Eti , Rahardjo Sri , Ainunnisa Rianza
Published: June 2024

Background: Inflammation affects labor by influencing contractions and
dilation. Pain, often linked to tissue ischemia, involves mediators like
TNF-α, substance P (SP), and nitric oxide (NO). Neuraxial analgesia,
including combined spinal epidural analgesia (SEA) with levobupivacaine,
is preferred for its effectiveness and minimal side effects in painless
labor. This study investigates these effects in parturients undergoing
SEA with levobupivacaine, contributing to the development of novel pain
medications and enhancing obstetric care. Methods: This study was
conducted at Permata Hati Metro Hospital in Indonesia. 60 expectant
mothers in active labor or in the third trimester scheduled for vaginal
delivery were enrolled. Blood serum samples were collected for analysis,
and to be processed by ELISA KIT for determining serum levels of TNF-α,
SP, and NO. Results: Following treatment, there were no significant
differences in TNF-α levels between groups before and after treatment (p
> 0.05). Although no significant difference in SP levels
was noted before treatment, a significant difference was evident after
treatment (p < 0.05). Moreover, a significant reduction in NO
levels was observed in the SEA group compared to the control group (p
< 0.05). SEA significantly relieved labor pain compared to the
control group (P < 0.05), accompanied by notable improvements
in vital signs and APGAR scores and labor duration (P <
0.001). Conclusion: SEA with levobupivacaine during painless labor
demonstrates a trend of decreasing TNF-α and SP levels while
significantly reducing NO levels. Although some mediators did not show
significance, clinical benefits were found in patients and babies.
A retrospective evaluation of complications in 1798 Equids undergoing 3T magnetic resonance imaging at one referral hospital
Authors: Manning Heath , Sampson Sarah
Published: June 2024

The current study aims to investigate the complication rate of equine
appendicular magnetic resonance imaging (MRI) performed under general
anesthesia at a tertiary referral center. 1655 horses, donkeys, and
mules were included in the study. A complication rate of 1.5% was found
in this 9-year study period. The most common complication was
post-anesthetic fever with 11 horses becoming pyrexic in the immediate
post-anesthetic period. Four of these horses went on to develop clinical
pneumonia and one horse had an outbreak of respiratory herpesvirus. The
incidence of neuropathy was 0.4% and colic was 0.4%. This study
concludes that peri-anesthetic antimicrobial administration would not
decrease the risk of complications in horses or donkeys undergoing
general anesthesia for MRI of the appendicular skeleton at this tertiary
referral center.
System Expansion Planning for Coordinated Source-network-load-stroage with Multiscale Uncertainties: A Case Study in China
Authors: Zhang Likai , Xu Enchao , Dan Yangqing , Wang Chenxuan , Wang Xiuli , song zhenzi , Wang Xifan
Published: June 2024

Development of the power system towards high renewable penetrated system
requires various flexibility resources to grow economically and
reliably. However, the multiscale uncertainties brought by the demand
and renewable energy sources is increasingly significant in the systems
with high proportion of renewable energy. Thus, this paper establishes a
system expansion planning model with multiscale uncertainties, in which
system elements from all side can develop harmonically, including
conventional units, renewable energy sources, transmission lines, energy
storage systems and demand responses. The proposed uncertainty
architecture consists of a long-term scenario tree which illustrate the
uncertain load growth and short-term stochastic scenarios which
represent the volatility of wind power, solar power and demand.
Simulation operations are then carried out on the planning schemes to
evaluate the expected reliability and economics of the resulting
systems. The case studies on a 6-bus system and a real-world system in
China are conducted to demonstrate the effectiveness of the model.
Results show that the flexibility not only comes from coordinated
flexibility resources but also the tree structure of planning decisions.
Simultaneous Solar-driven Interfacial Evaporation and Photo-Fenton Oxidation by Semiconducting Metal-Organic Framework from Waste Polyimide

Published: June 2024

The integrated technology of interfacial solar steam generation and
photo-Fenton oxidation has emerged as a promising way to simultaneously
mitigate freshwater scarcity and degrade organic pollutants. However,
fabricating low-cost, multi-functional evaporators with high water
evaporation and catalytic ability still presents a significant
challenge. Herein, we report the functional upcycling of waste polyimide
into semiconducting Fe-BTEC and subsequently construct Fe-BTEC-based
composite evaporators for simultaneous freshwater production and
photo-Fenton degradation of pollutants. Firstly, through a two-step
solvothermal-solution stirring method, Fe-BTEC nanoparticles ranging in
size from 20 to 100 nm are massively produced from waste polyimide, with
a band gap energy of 2.2 eV. The composite evaporator based on Fe-BTEC
and graphene possesses wide solar-spectrum absorption capacity, high
photothermal conversion capacity, rapid delivery of water, and low
enthalpy of evaporation. Benefiting from the merits above, the composite
evaporator achieves a high evaporation rate of 2.72 kg m-2 h-1 from
tetracycline solution, as well as the photothermal conversion efficiency
of 97% when exposed to irradiation of 1 Sun, superior to many
evaporators. What’s more, the evaporator exhibits the tetracycline
degradation rate of 99.6% with good recycling stability, ranking as one
of most powerful heterogeneous Fenton catalysts. COMSOL Multiphysics and
density functional theory calculation results prove the synergistic
effect of concentrated heat produced by interfacial solar steam
generation and catalytic active sites of Fe-BTEC on promoting H2O2
activation to form reactive oxidation radicals. This work not only
provides a green strategy for upcycling waste polyimide, but also
proposes a new approach to fabricate multi-functional evaporators.
Global analysis of surface ocean CO2 fugacity and air-sea fluxes with low latency
Authors: Chau Thi-Tuyet-Trang , Chevallier Frederic , Gehlen Marion
Published: June 2024

The Surface Ocean CO2 Atlas (SOCAT) of CO2 fugacity (fCO2) observations
is a key resource supporting annual assessments of CO2 uptake by the
ocean and its side effects on the marine ecosystem. SOCAT data are
usually released with a lag of up to 1.5 years which hampers timely
quantification of recent variations of carbon fluxes between the Earth
System components, not only with the ocean. This study uses a
statistical ensemble approach to analyse fCO2 with a latency of one
month only based on the previous SOCAT release and a series of
predictors. A retrospective prediction for the years 2021-2022 is made
to test the model skill, followed by the generation of fCO2 and fluxes
from January to August in 2023. Results indicate a modest degradation of
the model skill in prediction mode and open the possibility to provide
robust information about marine carbonate system variables with low
latency.

Authors: Prabowo Teguh , Firdaus Firdaus
Published: June 2024

Palembang City is a lowland area with an average height of 4-12 meters. When the rainy season arrives, flooding will occur in several locations, so it is necessary to build retention ponds to overcome this problem. This research aims to analyze whether the capacity of the retention pond is still capable of dealing with rainfall which has increased significantly over the last 10 years. From the research results, the largest rainfall was obtained using the gumbell method, and the results of the gumbell method analysis passed the chi-square and Smirnov-kolmogorof goodness-of-fit tests. The 10 year return period results obtained were 139.89 mm/hour and the peak discharge was 2.83 m3/s. The retention pond catchment area is 13.71 ha, with a rainwater storage volume in accordance with the Regulation of the Minister of Public Works of the Republic of Indonesia No. 11/PRT/M/2014 amounting to 8713.58 m3. The retention pond is considered capable of accommodating this rainfall because the retention pond capacity is 13,400 m3. Simulation results using HEC-RAS software showed that the water level was 3.25 meters.
