Abstract
The potential of sea waves, located precisely in the Berakit area, can be used as electrical energy on a small scale. Kelong is a floating house situated on the coast, which anglers (fishermen) use to catch fish. In the Bintan area, there are two types of kelong, namely floating kelong and cacak (permanent) kelong. Floating kelong, as the name implies, is a kelong that can be moved anywhere. During the fish season, the kelong are offered to the middle of the sea, but if the west wind season or not during the fish season, the kelong will be brought ashore. On the other hand, kelong cacak are usually not far from the beach or coast and cannot be moved and operated at night by using a lamp to catch cuttlefish or anchovies. This research was conducted on Kelong Cacak and Floating Kelong (pontoon) located in Berakit, Disability Telok Sebong, Kabubapen Bintan. The power generation system was built using the buoy method. Based on the research results, the wave power plant can be driven by sea waves with an average height of 6 cm and produces a voltage and continuously the voltage is not always stable. The maximum peak output voltage is up to 15 Volt DC; after knowing the test results, the power plant can supply as a charger for the battery in the kelong cacak of 0.8839 Volt DC with an average battery voltage of 10.052 Volt DC and total voltage charging is 0.37 Volt DC, with average battery voltage 11.4902 Volt DC on Floating Kelong (Pontoon).

Abstract
This research aims to design an automatic garbage collection system using a Programmable logic controller (PLC) and an Arduino Uno waste monitoring system. The function of this tool is to make people easier for clean marine debris, which is usually clean manually. In this case, operators or cleaners are only sufficient to wait for information in SMS if the trash bin is fully loaded. This study used an LDR sensor as input to respond to the state of the wastebasket and a DC motor used as a transmission system in transporting and moving the position of the wastebasket. In addition, using the ultrasonic sensor as input in the trash bin and a GSM SIM 900 A module functions as a medium for sending messages that the trash bin was full. Resultant of this study indicate that the tool can lift ±0.5 kg of waste per hour, with the heaviest weight that can be lifted ±0.7 kg and the lightest weight of ±0.5 kg with the most types of rubbish obtained in the form of plastic and other small debris.

Abstract
The grid-connected system can be an attractive solution to reduce electricity consumption, dependence on utility power, and increase electricity generation from renewable energy resources like wind energy for residential electricity users. Based on 33-year wind data (1983-2020), this study investigates the potential of wind energy at different locations ((Akkar, Baalbek, Beirut, Zahlé, Baabda, Nabatieh, Tripoli, and Sidon) in Lebanon using the Weibull distribution function. Monthly NASA wind speed data during the period (1983-2020) were used to estimate the wind energy potential. The result showed that the averaged wind speeds at the selected regions are varied from 3.695m/s to 4.457m/s at the height of 10m. Furthermore, the annual wind power density was estimated at various heights (10m, 30m, and 50m). The results demonstrated that small-scale wind turbines are recommended to be used for generating electricity from wind in the selected regions. Finally, the performance of WRE.060 / 6 kW (vertical axis wind turbine) and Proven WT 6000 (horizontal axis wind turbine) was done based on the monthly NASA wind speed database.

Abstract
Environmental pollution from heavy metals is becoming a growing concern due to the adverse effects it is causing throughout the world. This study aims to analyze heavy metal concentrations and identify heavy metal resistant bacteria in the bay of Manado. Sediment samples were collected from five bays in Manado. The concentrations of heavy metals As, Cd, Cr, Hg and Pb were analyzed using ICP-OES, and Hg using CV-AFS. Bacteria from the sediment were grown in nutrient broth media containing heavy metals As, Cd, Cr, Hg and Pb respectively. Microbiology and 16SrRNA gene analysis were used to identify the bacteria that grown on media containing varying concentrations of heavy metals. The results showed that the sediments from the five bays in Manado contained heavy metals with an average concentration of As <1mg/kg, Cd 1.8mg/kg), Cr 6.2mg/kg, Hg <0.07mg/kg). and Pb 11.2mg/kg. The results of microbiological and molecular analysis showed that 5 species of heavy metal resistant bacteria were Pseudomonas aeruginosa, Bacillus cereus, Staphylococcus arlettae, Acinobacter sp., and Brevibacterium sp. The five bacteria found to be resistant to heavy metals can be used to detoxify As, Cd, Cr, Hg, and Pb.

Abstract
Sewage sludge after urban wastewater treatment needs to be treated intelligently to get maximum benefits. This study proposes a method of anaerobic co-degradation of agricultural sludge and residues to both solve environmental problems and recover a large amount of biogas and organic fertilizers. The results show the potential for energy recovery from biogas and impact assessment of the application directly on the rice fields. It is estimated that biogas recovery from sludge treatment from wastewater treatment plants gives a calorific value of about 76 × 106 MJ/year. Results from the trial crop showed that fertilizer shows good supportability to the plant. The results show that the fertilizer from sewage sludge can be reduced and replaced by 50% to 100% of the number of chemical fertilizers but still give the same yield. The data show that the anaerobic co-digestion method is a suitable method for sludge treatment. The dual objective is to provide valuable benefits from recovered biogas and anaerobic digestion products.

Published: December 2021

Abstract
In the construction of road construction, soil bearing capacity, such as the CBR value, needs to be considered. In clay soil, the CBR value of the soil is low, so that stabilization material can be added to its repair. In this study, the stabilization materials used were waste materials in the form of bagasse ash and eggshell powder. Variations in the mixture of bagasse ash mixture used in this study were 7%, 10%, and 13% plus 3% eggshell powder. Testing in this study includes testing moisture content, sieve analysis, specific gravity, consistency limits, compaction testing, and CBR. The soil classification system used is the Unified classification (USCS), a test guideline based on SNI. From the CBR soaked test, it was found that the CBR value of clay soil increased along with the increase in the percentage of bagasse ash plus 3% eggshell powder and the increase in collisions on the soil. The percentage increase in the CBR value of clay soil with a mixture of stabilization to clay soil is 92.303%. at 65 blow. So that bagasse ash and eggshell powder greatly affect the increase in the CBR value of clay soil.

Abstract
The present study focuses on developing antimicrobial nanofibers with superhydrophobicity and insect repellent properties for wound dressing and biomedical applications. For the first time, Andrographis paniculata leaf extract was prepared and incorporated into ZnO nanofibers (AP-ZnO). The antifungal and antibacterial activities of AP-ZnO were tested using the agar plate method. Amid the bacteria and fungus strain tested, the prepared sample exhibited a greater efficiency against Staphylococcus aureus and Trichophyton rubrum respectively. AP-ZnO showed the highest larvicidal activity (100 ± 0.2) against Aedes aegypti, proving its insect repellent characteristics. The in vivo toxicity studies of AP-ZnO (100 μg ml−1) tested on Danio rerio ensure the biocompatibility of the prepared sample with maximum toxicity of 21.1% after 72 h, which is lower than commercial Prallethrin. Moreover, AP-ZnO-chitosan coated cotton fabric showed higher durability with contact angle (θ ∼ 151°) and was suggested to be used for self-cleaning applications in the biomedical sector. The examined results confirmed that AP-ZnO possesses different medicinal characteristics suitable for biomedical and pharmaceutical applications.
The ‘Corkscrew’ Journey of an Adaptation: Cultural Mobility in Hammett, Kurosawa, Leone, and Hill
Authors: Holtz Martin 
Published: December 2021

Abstract
Akira Kurosawa’s Yojimbo (1961) has long been recognized as a quasi-adaptation of Dashiell Hammett’s Red Harvest (1929), even if it relates much more closely to Hammett’s short story ‘Corkscrew’ (1925). Yojimbo was remade as the Italian Western Fistful of Dollars (1964) by Sergio Leone. The material finally ‘came home’ when Walter Hill adapted it as Last Man Standing (1996) that returns to the 1920s American desert town setting of the original story. This contribution seeks to examine the inflections of the individual incarnations that the material has undergone on its journey through various cultural contexts. The main argument is that the story of the outsider infiltrating a corrupt town and ‘cleansing’ it by playing off two gangs against each other has lent itself to commentary on transnational cultural exchange and mobility. ‘Corkscrew’ expresses anxiety over the integrity of cultural boundaries, Red Harvest expresses the inherent corruption of a ‘hermetic’ culture, Yojimbo uses the story to highlight the uneasy relation between tradition and Westernization in Japan while simultaneously drawing attention to Kurosawa’s status as ‘Western’ director and embraces a guarded cultural mobility, Fistful of Dollars empties the signs, icons, and narratives that make up the expressions of culture of any essentialist meanings and so stages cultural mobility as the shifting play of signifiers, endlessly transgressing acquired meanings and cultural boundaries, and Last Man Standing, finally, in reclaiming the Americanness of the story simultaneously forgoes any cultural specificity by reducing it to an excessive pastiche of prior elements.
Family caregivers emphasise patience and personal growth: a qualitative analysis from the Caregiving Transitions Study
Authors: Blinka Marcela D , Liu Chelsea , Sheehan Orla C , Rhodes J David , Roth David L 
Published: December 2021

Abstract

Background
informal caregiving for family and friends is becoming increasingly common due to the rising prevalence of chronic conditions and a shortage of affordable care options. While the impact of caregiving on caregivers’ health is well-documented, nuances in caregivers’ experiences may not be captured in quantitative studies. We aimed to better understand caregivers’ perception of their experiences through qualitative analysis.

Methods
participants were from the Caregiving Transitions Study (CTS), which is ancillary to the REasons for Geographic and Racial Differences in Stroke Study. We analysed responses from 150 caregivers to an open-ended question at the end of the CTS telephone interview concerning additional information about their caregiving experiences. We identified main themes and examined differences by sex, condition and relationship to the care recipient.

Results
four major themes were identified: cultural/family expectations; growth opportunities; and reciprocity; stressors and challenges and recommendations. Male caregivers more often indicated that their motivation for taking on this role was their sense of duty towards family, while female caregivers focused on the challenges and burden of caregiving that they experienced. Overall, caregivers highlighted the importance of patience and the positive impact of caregiving, such as opportunities for personal growth, acquiring new skills, and finding fulfillment and gratitude.

Conclusions
family caregivers shared both positive and challenging experiences as well as the impact that these experiences had on their lives. Understanding the full spectrum of the caregiving experience will help inform how the community and the health care system can best support caregivers in their roles.

AbstractTemporal lobe epilepsy is associated with MRI findings reflecting underlying mesial temporal sclerosis. Identifying these MRI features is critical for the diagnosis and management of temporal lobe epilepsy. To date, this process relies on visual assessment by highly trained human experts (e.g. neuroradiologists, epileptologists). Artificial intelligence is increasingly recognized as a promising aid in the radiological evaluation of neurological diseases, yet its applications in temporal lobe epilepsy have been limited. Here, we applied a convolutional neural network to assess the classification accuracy of temporal lobe epilepsy based on structural MRI. We demonstrate that convoluted neural networks can achieve high accuracy in the identification of unilateral temporal lobe epilepsy cases even when the MRI had been originally interpreted as normal by experts. We show that accuracy can be potentiated by employing smoothed grey matter maps and a direct acyclic graphs approach. We further discuss the foundations for the development of computer-aided tools to assist with the diagnosis of epilepsy.

Abstract
The ability of seeds to withstand drying is fundamental to ex situ seed conservation but drying responses are not well known for most wild species including crop wild relatives. We look at drying responses of seeds of Musa acuminata and Musa balbisiana, the two primary wild relatives of bananas and plantains, using the following four experimental approaches: (i) We equilibrated seeds to a range of relative humidity (RH) levels using non-saturated lithium chloride solutions and subsequently measured moisture content (MC) and viability. At each humidity level we tested viability using embryo rescue (ER), tetrazolium chloride staining and germination in an incubator. We found that seed viability was not reduced when seeds were dried to 4% equilibrium relative humidity (eRH; equating to 2.5% MC). (ii) We assessed viability of mature and less mature seeds using ER and germination in the soil and tested responses to drying. Findings showed that seeds must be fully mature to germinate and immature seeds had negligible viability. (iii) We dried seeds extracted from ripe/unripe fruit to 35–40% eRH at different rates and tested viability with germination tests in the soil. Seeds from unripe fruit lost viability when dried and especially when dried faster; seeds from ripe fruit only lost viability when fast dried. (iv) Finally, we dried and re-imbibed mature and less mature seeds and measured embryo shrinkage and volume change using X-ray computer tomography. Embryos of less mature seeds shrank significantly when dried to 15% eRH from 0.468 to 0.262 mm3, but embryos of mature seeds did not. Based on our results, mature seeds from ripe fruit are desiccation tolerant to moisture levels required for seed genebanking but embryos from immature seeds are mechanistically less able to withstand desiccation, especially when water potential gradients are high.
Carthaginians Beyond the Ocean: Comparison, Justification, and Inversion in the Hypothesis of the Carthaginian Discovery of America
Authors: Fernández Camacho Pamina 
Published: December 2021

AbstractAfter the American continent was discovered, Spanish intellectuals exerted their ingenuity in an attempt to explain the existence of those hitherto unknown territories, and engaged in controversies about the moral and legal right to exploit them. The use of classical sources as authorities was common in those debates. In this article, we focus on the mention by Ps.-Aristotle and Diodorus of an island in the Atlantic Ocean, discovered and exploited by Carthaginians until the colonization process came to a dramatic end. We study the use of this story in connection with America, exploring its role in the controversy about rights of discovery and its implications for the debate about the ethnicity of indigenous peoples and the justification of their conquest. This led to the establishment of a comparison between the ancient colonization of Spain by the Carthaginians and the colonization of America by the Spaniards, where the latter was presented as an improvement or positive reverse of the former. Finally, we present the hypothesis that this Carthaginian colonization, as it was imagined in the early sixteenth century, was inspired by contemporary events taking place in America, and that this had an impact on the understanding of ancient Spanish history for centuries.
