Abstract
In this study, hydrodeoxygenation (HDO) process of bio-oil from coconut shell waste was catalyzed by active Sarulla natural zeolite (ZAS) supported by Co metal and a combination of Co-Mo metal. The resulting bio-oil HDO product is expected to have good physicochemical stability during the storage period so as to increase its potential as an alternative source of hydrocarbon energy. Preparation and activation of ZAS catalyst with 3M HCl and calcination with N2 gas flow. Impregnation of Co and Co-Mo into ZAS was carried out by wet impregnation method followed by oxidation and reduction with O2 and H2 gas flow. Several important properties of the catalyst were characterized by XRD, SEM, FTIR, and BET methods. Bio-oil HDO process is carried out in fixed bed reactor with H2 gas flow at a certain temperature for two hours. Analysis of physicochemical properties and stability of bio-oil products includes analysis of acid number, viscosity, elementary content, HHV, and component analysis using GC-MS. The data obtained showed that the loading of two metals increased the spesific surface area, volume and pore size, but decreased the crystallinity of the catalyst. Based on the distribution of HDO products, it indicates that monometal catalysts tend to produce more liquid phase, coke, and gas while bimetallic catalysts tend to produce more organic phase. Viscosity and acid number of bio-oil catalyzed by Co-Mo/ZAS is lower than that of Co/ZAS. Co/ZAS catalyst showed high selectivity towards the aqueous phase. The bio-oil catalyzed by Co/ZAS has a higher HHV and a higher viscosity and lower oxygen content as a result of the release of hydrogen bound oxygen into water molecules. Thus, it can be assumed that the deposition of Co and Co-Mo on zeolite has a different effect on the characteristics of zeolite and its activity as a catalyst.

Published: February 2022

Abstract
The quality of liquid smoke and charcoal product yield can be improved by conducting pyrolysis process through indirect heating process. However, a great huge of energy is required to reach the exact operating temperature. In this experiment, slow pyrolysis of coconut shell is performed for liquid smoke and charcoal production using indirect method where the feedstock is just heated in a tube by using LPG as the heat source. The effect of feedstock size and the operating temperature on the liquid smoke and charcoal yields are investigated by varying the coconut shell sizes in the ranges of 1 to 7 cm2, while the operating temperature is expected as low as possible to reduce the energy required. The optimum process conditions for maximizing the two products yields and quality were also identified to meet the user requirement. The various characteristics of liquid smoke obtained under the optimum conditions for maximum yield are identified based on standard test methods. Data from a simple way of charcoal and liquid smoke production during preliminary research of this study indicated that the coconut shell sizes, and the operating temperatures are the crucial parameter during process.

Published: February 2022

Abstract
Construction of a structure, whether in the form of buildings, bridges and roads, begins with planning. Planning comprise of foundation and the main structure above the ground. Particularly within planning such foundation require data related to the bearing capacity of the soil. This data is obtained from the results of soil testing in the field, one of which is by using the Standard Penetration Test (SPT) method. The test data are then analysed and interpreted into a value that describes the strength of the soil based on the origin. In the development of infrastructure such as toll roads, a large amount of data specifying bearing capacity of the soil is required. The more data that is known, the design planning and construction implementation in the field will be better and have better quality. Acquiring the bearing capacity data in the field requires no small fee and also a relatively long testing time. One solution that can be used is to map the distribution pattern of the bearing capacity of the soil in a very large area, for example the island of Sumatra. The island of Sumatra is part of Indonesia, where infrastructure development in the form of toll roads is currently underway. The infrastructure construction of this toll road is carried out continuously, starting from Aceh to Lampung. The distribution pattern of the soil bearing capacity on the island of Sumatra can be used as initial data and an overview of the local soil bearing capacity for better pre-design and budget planning.

Abstract
Construction of high-rise buildings is currently flourishing implemented that serves as an office, hall, hotel, or home. High-rise buildings in general minimize the use of construction materials that has a heavy weight to reduce the building load and achieving efficiency. One of construction parts that can be minimized weight is a wall construction. The materials of partition wall which produced are glass, gypsum, concrete and wood. This research uses of wood fiber materials from oil palm trunks which have reached the age of replanting. It is constituted by the growing oil palm plantations and palm oil mills in Indonesia so that it will also increase waste produced. This research uses experimental methods to determine the mixture of adhesive and oil palm trunk fiber (OPTF) in order to reach the standards of strength by find out the physical and mechanical properties of the partition. The result shows that using ratio 70:30 of adhesive and OPTF reach the standard partition wall that serves as partition board and decorative panel.

Abstract
An imaging heavy ion beam probe (i-HIBP) diagnostic, for the
simultaneous measurement of plasma density, magnetic field and
electrostatic potential in the plasma edge, has been installed at
ASDEX Upgrade. Unlike standard heavy ion beam probes, in the i-HIBP
the probing (heavy) ions are collected by a scintillator detector,
creating a light pattern or strike-line, which is then imaged by a
camera. Therefore, a good characterization of the scintillator
response is needed. Previous works focused on the scintillator
behaviour against irradiation with light ions such as hydrogen and
alpha particles. In this work we present the characterization of
several scintillator screens — TG-Green
(SrGa2S4:Eu2
+), YAG-Ce
(Y3Al5O12:Ce3
+) and P11 (ZnS:Ag) —
against irradiation with 133Cs+ ions, in an energy range
between 5 and 70 keV and ion currents between 105 and 107
ions/(s·cm2). Three main properties of the scintillators
have been studied: the ionolumenescence efficiency or yield, the
linearity and the degradation as a function of the fluence. The
highest yield was delivered by the TG-Green scintillator screen with
> 8·103 photons/ion at 50 keV. All the samples showed a
linear response with increasing incident ion flux. The degradation
was quantified in terms of the fluence F1/2, which leads to a
reduction of the emissivity by a factor of 2. TG-Green showed the
lowest degradation with F1/2= 5.4·1014
ions/cm2. After the irradiation the samples were analyzed by
Scanning Electron Microscopy (SEM), Rutherford Backscattering
Spectrometry (RBS) and Particle Induced X-ray Emission (PIXE). No
trace of Cs was found in the irradiated regions. These results
indicate that, among the tested materials, TG-Green is the best
candidate for the i-HIBP detector.
Environmental context and socio-economic status drive plastic pollution in Australian cities
Authors: Schuyler Qamar , Hardesty Britta Denise , Lawson T J , Wilcox Chris 
Published: February 2022

Abstract
Plastic pollution is a critical environmental concern. There is a growing focus on this transboundary issue, and a corresponding increase in public and government awareness. Understanding the key factors associated with litter and mismanaged waste on land will help to predict where and how waste enters the environment, providing opportunities for low cost, effective interventions. There exist only a few large-scale datasets with which such analyses can be conducted. To fill this knowledge gap we analysed a national, designed survey dataset of litter in the environment from Keep Australia Beautiful (2007–2017). We found that debris decreased significantly, with a nearly 6% decrease over the decade. Using generalised additive model modelling of 17 653 surveys at 983 sites around Australia, we found that site type, land use, state, population, and socio-economic status had the strongest relationships (in decreasing order) with litter distribution. Higher levels of litter were found in economically and socially disadvantaged neighbourhoods. Site types related to transitory human use such as highways and carparks, had more litter than areas with higher aesthetic or cultural value such as beaches, parks, and residential neighbourhoods. Sites that were sources of litter, such as shopping centres and retail strips, also had elevated litter counts, as did surveys near waterways. This enhanced understanding of the factors that influence litter deposition will help to craft more effective policy solutions, and can also improve our models of litter loads on land, and subsequent input to the ocean.
Income-based inequality in post-disaster migration is lower in high resilience areas: evidence from U.S. internal migration
Authors: Chen Ted Hsuan Yun , Lee Boyoon 
Published: February 2022

Abstract
Residential relocation following environmental disasters is an increasingly necessary climate change adaptation measure. However, relocation is among the costliest individual-level adaptation measures, meaning that it may be cost prohibitive for disadvantaged groups. As climate change continues to worsen, it is important to better understand how existing socioeconomic inequalities affect climate migration and how they may be offset. In this study we use network regression models to look at how internal migration patterns in the United States vary by disaster-related property damage, household income, and local-level disaster resilience. Our results show that post-disaster migration patterns vary considerably by the income level of sending and receiving counties, which suggests that income-based inequality impacts both individuals’ access to relocation and the ability of disaster-afflicted areas to rebuild. We further find evidence that income-based inequality in post-disaster outmigration is attenuated in areas with higher disaster resilience, not due to increased relocation out of poorer areas but instead because there is decreased relocation from richer ones. This finding suggests that, as climate adaptation measures, relocation and resilience-building are substitutes, with the implication that resilience incentivizes in situ adaptation, which can be a long term drain on individual wellbeing and climate adaptation resources.
The effect of temperature on outdoor recreation activities: evidence from visits to federal recreation sites

Abstract
This paper uses over 30 million individual-level trips in federal recreation locations to investigate the impact of short-term temperature shocks on outdoor recreation activities. Our results show that in the short term, a

C temperature increase during the last six months increases the total trip duration by 1.197 d (or a 4.12% increase) and the total number of trips by 0.472 (or a 5.44% increase) at the zipcode-month level. The positive effect is primarily driven by the increased number of trips and more in-state travel. We find that the impact of temperature on the number of recreation trips generally increases under a higher temperature. When the monthly temperature is below

C, the temperature increase will reduce the number of trips as individuals in low-temperature regions are likely to reduce travel when the temperature gets warmer.
Tuning the band gap and effective mass of black arsenic phosphide monolayer by in-plane strain
Authors: Mao Yuliang , Yao Zihua , Wu Runlin , Zhou Xing , Du Yuting 
Published: February 2022

Abstract
Based on first-principles calculations, the electronic properties of a black AsP monolayer were investigated by applying an external strain. It was found that the electronic property and effective mass of black AsP monolayer exhibits strong anisotropy. Comparing with the armchair direction, the zigzag direction was more resistant to elastic deformation. When the strain was applied along the zigzag direction, a direct-indirect-direct transition of the band gap occurred with increasing tensile strain and compressive strain. The direct to indirect transition occurred at a −2% compressive strain when the strain was applied along the armchair direction. The direct-indirect transition occurred at biaxial compressive and tensile stains of −3% and 3%, respectively. In addition, the effective mass of electrons and holes along the armchair direction is an order of magnitude smaller than that associated with the zigzag direction, suggesting that electron and hole transport will occur preferentially along the armchair direction. Moreover, we found that the effective mass of the black AsP monolayer can be significantly tuned by strain.
Pay as you throw; an exploratory study on a market-based approach to the environmental problems caused by public littering in Nigeria
Authors: Umerie Cletus Alexander , Nnamoko Joy Nzube 
Published: February 2022

Abstract
This paper provides an overview of environmental policy research focusing on market-based instruments, and their applicability to developing countries, in particular Nigeria. It also addresses more general developments in the field of deposit-refund systems (DRSs) and explores the practicality of a DRS to litter management in Nigeria. A prominent theme of our discussion is economic instruments, where different approaches will be explored to understand the link between compliance and neglect inherent in environmental issues of a developing country such as Nigeria. Where the objective is to reduce littering, a DRS was considered the choice for the framework of this study, after researches detailed its benefits and relevance to the research problem. DRS is subsequently discussed as a policy intervention, and the feasibility of introducing the system in Nigeria is evaluated. By understanding the implementation mechanisms, the economic viability and environmental effectiveness of a DRS, it is concluded that a DRS can support a country’s drive to solve some of its pressing issues of environmental concerns even with the bare minimum of government administration. The consolidation of information from this research can kick-start the conversation on ways to incorporate this system as part of Nigeria’s solid waste management policy.

Published: February 2022

Abstract

Background
Melanoma is the second most common cancer in young adults. Social media may be a means to conduct interventions to increase sun safety in young adults.

Purpose
We conducted a randomized proof-of-concept pilot trial to evaluate the feasibility and acceptability of a dissonance-based social media intervention designed to promote sun safety in young adult tanners.

Methods
Young adult tanners (N = 66) were randomized into two 4-week interventions in which participants were incentivized to create content for a social media campaign on healthy skin or healthy lifestyle. Feasibility outcomes included retention, participation, acceptability, and contamination. We also examined the impact of participation on motivation to engage in the target health behaviors and outdoor tanning intentions.

Results
Retention was 100%. Most Healthy Skin (88%) and Healthy Lifestyle participants (91%) created ≥1 post. Acceptability was high with 94% and 97% of participants in Healthy Skin and Healthy Lifestyle conditions, respectively, agreeing they would recommend the campaign to a friend. At 4 weeks, Healthy Skin participants reported greater declines in motivation to tan indoors (p = .0017) and outdoors (p = .0003), and greater increases in motivation to wear sunscreen (p = .0009) and protective clothing (p = .0342). Healthy Skin participants reported greater declines in intentions to tan outdoors in the next year (p = .0286).

Conclusions
A dissonance-based, social media sun safety intervention was feasible and acceptable. Future research should examine the efficacy and longer-term effects of this intervention in young adults at elevated risk for skin cancer.

Non-inferiority of a home-based videoconference physical training program in comparison with the same program administered face-to-face in healthy older adults: the MOTION randomised controlled trial
Authors: Langeard Antoine , Bigot Lucile , Maffiuletti Nicola A , Moussay Sébastien , Sesboüé Bruno , Quarck Gaélle , Gauthier Antoine 
Published: February 2022

Abstract

Background
older adults often fail to reach the recommended amount of physical activity to prevent the age-related decline in metabolic, cardiorespiratory and muscular function. Effective home-based physical training programs could neutralise barriers preventing older adults from being active, and administration/supervision through videoconference may be an optimal solution. The present randomised controlled trial aimed to test the non-inferiority of training program administered through videoconference against the same program administered face-to-face in healthy older adults.

Methods
participants were randomised in a no-training control group (n = 13), a face-to-face training group (n = 15) and a videoconference training group (n = 13). The intervention groups completed the same home-based, structured, progressive and combined training program for 16 weeks, 1-h twice a week. Pre-intervention and post-intervention evaluations included body composition, cardiorespiratory fitness and muscle function measures.

Results
non-inferiority of videoconferencing against face-to-face training was observed for changes in body weight (P &lt; 0.01), fat mass (P = 0.015), maximal aerobic power (P = 0.013), maximal heart rate (P = 0.034), maximal oxygen consumption (P &lt; 0.01), knee extension strength (P = 0.044) and lower limb power (P = 0.019), but not for muscle mass (P = 0.067), handgrip strength (P = 0.171), trunk extension strength (P = 0.241) and knee flexion strength (P = 0.462).

Conclusion
a training program administered through videoconferencing was not inferior to the same program administered face-to-face for reducing body weight and fat mass, and for improving maximal aerobic power and oxygen consumption as well as lower limb power and knee extension strength in healthy older subjects. However, videoconferencing training was not as effective as face-to-face training for improving handgrip, trunk extension and knee flexion isometric strength.

Published: February 2022

Abstract
Alcohol consumption represents a major factor of morbidity and mortality, with a wide range of adverse medical implications that practically affect every organ system. It is the fifth major cause of deaths in men and women and causes up to 139 million disability-adjusted life years. Solid evidence places the risk as undoubtedly correlated to the length of time and amount of alcohol consumption. While alcohol-related liver disease represents one of the most studied and well-known consequences of alcohol use, the term itself embodies a wide spectrum of progressive disease stages that are responsible for almost half of the liver-related mortality worldwide. We discuss the staged alcohol-related fatty liver, alcohol-related steatohepatitis and, finally, fibrosis and cirrhosis, which ultimately may end up in a hepatocellular carcinoma. Other comorbidities such as acute and chronic pancreatitis; central nervous system; cardiovascular, respiratory and endocrine system; renal disease; urological pathologies; type 2 diabetes mellitus and even infectious diseases are reviewed in their relation to alcohol consumption. This article reviews the impact of alcohol use on different systems and organs, summarizing available evidence regarding its medical implications. It examines current basic and clinical data regarding mechanisms to highlight factors and processes that may be targetable to improve patient outcomes. Although alcohol use is a part of many cultural and social practices, as healthcare providers we must identify populations at high risk of alcohol abuse, educate patients about the potential alcohol-related harm and provide appropriate treatment.
