Authors: Nguyet N T A , Bau N V 
Published: October 2023

Abstract
Con Dao is an archipelago off the coast of Ba Ria - Vung Tau province, in the southeast Vietnam, including 16 islands with a total area of 72.81 km2. Through surveys and various secondary sources, the article focuses on analyzing the geo-natural, geo-political and geo-economic resources of Con Dao, thereby proposing the solutions to promote the position resources of Con Dao for sustainable economic development. Results indicate that topography, geology, and ecological landscape have created a great value for Con Dao in terms of geo-natural resources and favorable habitat for living species and humans. Regarding the value of geo-political position, as a protruding archipelago located at the crossroads of international sea routes, the intersection point of two maritime routes from South to North Asia and the maritime route from West to East and vice versa, and the gateway of Vietnam with ASEAN countries, Con Dao plays an important role in the protection of Vietnam’s past and current national rights and interests in the sea. In terms of the value of geo-economic position, Con Dao belongs to a district-level administrative unit in Ba Ria - Vung Tau province as a prioritized position for the development of the sea-island economy of the country. With the rich and diverse natural resources, human resources, healthy environment, and location in an important position on international trade routes, Con Dao is a favorable area for the development of marine economic sectors such as fisheries, marine conservation and tourism along with other types of services. However, in reality, the enhancement of the position resources of Con Dao for economic development is still limited, inconsistent and unsustainable.

Abstract
Selecting the location for domestic waste disposal and waste treatment plant is a crucial issue as it directs impacts on health-related, social and environmental factors. One of the effective tools for solving this problem is Geographic Information System (GIS) which employs Multi-Criteria Analysis (MCA). This research aims to identify the optimal locations to evaluate the existing solid waste landfill site and waste treatment plant for land use planning in Phu Quoc island in Kien Giang province for reducing the plastic waste leaking into the ocean. The island is categorized as the urban at small scale with population of 100,000 to 500,000; construction of waste treatment facilities (middle scale) with the capacity of 500 tons per day is now planned. These contents of this study are the new contributions to the methodology for data processing and data collection. The main research methods were applied to geo-spatial data collection derived from maps, satellite imagery, and existing local land use planning information. The criteria for site selections for solid waste landfill were chosen under Vietnamese construction standards and Ministry of Natural Resources and Environment, Ministry of Construction, international regulation, and the provincial policy. Then Analytic Hierarchy Process (AHP) and GIS processes were based on 9 main factors such as (1) distance to an urban area, (2) distance to a rural village, (3) distance to the water surface, (4) distance to roads, (5) distance to electrical supply stations, (6) distance to industrial zones, (7) distance to waste disposal, (8) compliance with the local land use planning, and (9) agreement for approval for site locations for solid waste landfill from the local community. National standard requirements for waste landfill site selection are adjusted to meet the local context. The updated land use data source is applied, and the recommendation for the suitability of the waste landfill sites is formulated. Study results showed that there are four potential sites located in Cua Can, Bai Thom, and Ham Ninh communes with a total area of 84.5 hectares. These areas are identified to be very suitable for solid waste landfill locations and location of waste treatment plants; and corresponding to the land use planning of the local government. The results of the study also recommend policies and solutions for environmental management in the coastal area of Phu Quoc island.

Authors: Pambhar Ankitkumar C , Valaki Janak B 
Published: October 2023

Abstract
Single-point incremental forming (SPIF) has been developed as a customized substitute of traditional sheet metal forming techniques. SPIF is a great method for rapidly prototyping sheet metal objects, although it faces challenges in achieving surface quality and thickness distribution. In this investigation, sheets of Cu-Al bimetallic composite were formed utilizing a hemispherical-headed tool with a variety of step depths, spindle speeds, forming speeds, layer arrangements, and lubrication types. Surface roughness and minimum thickness were evaluated as response parameters in relation to the significance of process variables. The best surface quality was attained with 0.4 mm step depth, 750 mm/min forming speed, and 1500 rpm spindle speed with liquid lubrication support for both types of layer arrangements. Layer arrangement and lubricant type were the decisive factors for the minimum thickness response parameters.

Abstract
The generalised gradient approximation (GGA) and ultrasoft pseudopotential (US PP) methods to the function of Perdew-Burke-Ernzerhof (PBE) approach are utilised for density functional computation of CuInS2. It enables the prediction of thermoelectric characteristics, including Seebeck coefficient, thermal conductivity, electrical conductivity, magnetic susceptibility, specific heat, power factor and figure of merit by semi-classical Boltzmann approach. At 800 K, the highest magnitude of Seebeck coefficient is estimated as 6.91× 10-5 V·K-1. The maximum figure of merit (zT) is predicted as 1.04 × 10-4 at 800 K. Findings from this study suggest that CuInS2 has prospective to be used in the thermoelectric power generating sector.

Abstract
In recent years, due to unique physical and chemical properties of nanoparticles, its uses to disrupt biofilm of bacteria are revolutionary steps in antimicrobial research. To use in bioprocess the silver nanoparticles should be biocompatible and free from toxic chemicals. In the present study we report a cost effective and environment friendly route for green synthesis of silver nanoparticles using banana flower extract (BFE) as reducing as well as capping agent. This plant has been opted for the present study for its known medicinal properties and it is easily available. The biosynthesized silver nanoparticles are characterized by UV–Vis spectroscopy which showed a broad peak at around 450 nm, indicated the stability of synthesized silver nanoparticles. Antimicrobial potential of silver nanoparticles synthesized were tested against both Gram positive and Gram-negative bacteria. It was found to be effective against both of them and it showed maximum activity against Gram positive bacteria S. aureus. Silver nanoparticles (AgNPs) have been imposed as an excellent antimicrobial agent being able to combat bacteria in vitro and in vivo causing infections. The results show green synthesized silver nanoparticles, using BFE extract, have a potential to inhibit the growth of bacteria.

Published: October 2023

Abstract
Sm2O3 doped boro-zinc-vanadate glass systems were synthesised by following the melt quenching method. XRD patterns indicated largely non-crystalline nature with few nano-crystallites. Room temperature density was measured. Molar volume and various polaron parameters were estimated. Density and molar volume are found to vary non-linearly with samarium concentration. Conductivity has been measured by two probe technique for temperature range 303K - 573K. High temperature conductivity obeyed the small polaron hopping (SPH) theory. Activation energy for conduction in the temperature regime of small polaron theory is found to vary from 0.249 eV to 0.368 eV non-linearly with Sm2O3 concentration. The conductivity data at low temperature deviated has been looked into using Mott’s VRH model and the density of states at Fermi level were determined. Shimakawa’s multiphonon tunnelling model has also been applied to the low temperature conductivity and found linearity between logarithmic conductivity, ln(σ) and logarithmic temperature ln(T) as predicted by the model. The temperature exponent values obtained from Shimakawa’s model fit are found to be in good agreement with literature. Therefore, it is concluded that at low temperature, carrier multiphonon tunnelling is the charge transport mechanism in the present glasses.

Authors: Kumar S R , Anurag Kumar 
Published: October 2023

Abstract
In this study, we present a one-pot approach for the large-scale synthesis of multilayer to few-layer graphene nanosheets in an aqueous medium that is cost-effective, environmentally friendly, high-yielding, and simple. This electrochemical exfoliation method produces low defect and high yield graphene nanosheet products and is more efficient than chemical exfoliation methods. Two highly oriented pyrolytic graphite plates (HOPG) are utilized as the anode and cathode in this method, which also incorporates two electrode geometry configurations. XRD, HRTEM, AFM, XPS, and Raman spectroscopy are used to describe graphene nano-sheets. Raman characterization supports graphene’s inherent qualities. By using cyclic voltammetry, the electrochemical performance of the produced nano-sheets is evaluated.

Abstract
Aquaponics refers to the growth of fish and plants in a single platform. As the demand for land increases due to urbanization, the growing of crops and other vegetables with less soil area is needed. Growing plants and aquatic animals in the same environment will save the usage of soil and the consumption of water levels will also be minimized. To automate the Aquaponics environment and to monitor the plant growth from the seed level to the fruiting level, a system is designed. This proposed method will help the user to monitor the water quality parameters like pH, humidity, and temperature and intimates the user about the current level, and alarms the user for any overshooting. The proposed system is designed, fabricated, and tested in laboratory conditions. The plant growth is monitored from the starting seed stage to the final fruiting stage. The essential nutrients required for plant growth are monitored and the discrepancy is satisfied accordingly. The bacteria and the microorganisms present in the soil decompose the plant waste into food that aquatic animals consume. The remains and excreta of the aquatic animals are sediments and given to plants as nutrition. Due to proper plumbing, water consumption is reduced. Different plants require different nutrient levels for their growth. The nutrient levels are listed and the test values are loaded into the microprocessor according to the plant selected. Here spinach is selected. The pH level, temperature level, and humidity levels of the soil and the water are monitored and the values are updated to the user using the web interface. From the web page, the user can get the parameter values and a comparison can be made accordingly.

Abstract
In the present study, an attempt was made to develop Self Compacting Alkali Activated Slag Concrete mixes incorporating Bagasse Ash as binder content. This study investigates the physical and mechanical properties of Bagasse Ash based Self Compacting Alkali Activated Slag Concrete (BSAASC) with varying proportions of Bagasse Ash. Lime and GGBS (Ground Granulated Blast Furnace Slag) are used along with Bagasse Ash as binder materials in the BSAASC. The total binder content was restricted to 600kg/m3 containing Bagasse Ash at 10%, 20% and 30% of total binder content. The solution-to-binder ratio was 0.6. the dosage of Na2O was varied by 5%, 6% and 7%. The molarity of the alkaline solution is 1M. By using Minitab Statistical Software nine mixes were produced with 3 factors and 3 levels. The analysis was done by Desirability Function Approach (DFA) to check the effectiveness of the considered factors. The workability tests for properties of concrete samples are carried out according to EFNARC guidelines. Microstructural studies such as SEM, EDX and XRD analysis were also carried out, showing denser morphologies indicating effective activation of slag by the alkaline solution.

Authors: Nafea Safa N. 
Published: October 2023

Abstract
The patch antenna was used recently for ISM band (5.725 – 5.875) GHz, the patch antenna suffers of being an antenna with low gain as well as narrow operating bandwidth with high side lobe level (SSL) radiation pattern. A single plane with low profile and easy fabrication microstrip patch antenna has been proposed in this work was presented for directive communications and operates in Industrial, Scientific, and Medical (ISM) band 5.8 GHz with low SLL radiation pattern and gain of 5.20 dB for pint to point (directive). The gain of antenna has been increased while SLL decreased due to shifting the radiating patch and feeder of antenna with specific distance toward –ve side of the X-axis without any need for using techniques which would increase overall dimensions of antenna. The antenna has been printed on Arlon AD 250 substrate. The simulated results of antenna’s gain, operating frequency, bandwidth, return loss, and radiation pattern are presented. CST Microwave studio software was used in this design simulation.

Published: October 2023

Abstract
The third-order optical nonlinearities of methyl green in aqueous solution are studied by the Z-scan technique using a femtosecond laser at 800 nm. The valley shape in the open aperture measurements reveals the presence of reverse saturable absorption effect, which is ascribed to the three-photon absorption process. The closed aperture Z-scan traces demonstrate a negative sign for the nonlinear refractive coefficient, indicating the self-defocusing optical nonlinearity. Furthermore, the magnitudes of the nonlinear refractive index n
2, the three-photon absorption coefficient α
3, and the real part of the third-order nonlinear optical susceptibility Re χ
(3) are determined and found to be linearly proportional to the dye concentration within the investigated range. Our results suggest that methyl green may be a hopeful candidate for applications in nonlinear optics.

AbstractAmong the richest ecosystems in bioluminescent Coleoptera in Brazil, the Cerrado (savannas) is the most threatened one by agricultural expansion. The Emas (PNE) and Chapada dos Guimarães (PNCG) National parks are 2 of the last main remnants of the original Cerrado ecosystems in Central-west Brazil. During the past 3 decades, we have conducted several expeditions to collect, observe and study bioluminescent beetles occurring in the PNE and surrounding farms. More recently we also started to investigate the PNCG. We recorded a total of 51 bioluminescent species, including fireflies (n = 29), click beetles (n = 11), phengodids (n = 10), and staphylinids (n = 1). The PNE region was the richest one, especially for phengodids (n = 9). Among the habitats that compose the Cerrado physiognomy, the Cerrado and cerradão hosted most of the bioluminescent species, followed by forest, open fields and marshes. Most fireflies inhabiting the Cerrado ecosystem emit yellow-green light, whereas most click beetles emit predominantly green light, and among phengodid species, orange and red-light emission was found in 3 species. The spectacular click beetle Pyrearinus termitilluminans Costa-lodging luminous termite mounds were found in PNE and also reported for the first time at PNCG. In the farms around the PNE, however, a declining number of bioluminescent species was recorded in cerradão areas after the replacement of the surrounding cattle pastures by sugarcane plantations, especially adult phengodid males that were no longer attracted to light traps. Habitat reduction, use of agricultural pesticides and artificial night lighting are thought to be the major causes of such impact on bioluminescent beetle diversity.

Abstract
Social animals, and ants, in particular, exhibit a range of cooperative behaviors. One such behavior is the rescue of group members, which cannot return to the nest by themselves. However, if several group members need to be rescued, how do ants prioritize whom to save first? Furthermore, when food is offered in parallel, do ants prioritize feeding over rescuing? We studied the rescue behavior of the desert ant Cataglyphis niger. Workers invest more time in rescuing pupae than adult workers, perhaps because the value of brood is higher than that of older workers serving as foragers. Specific rescue behaviors, pulling the trapped individual or digging around it, differed when directed toward adults or pupae: rescuing workers more often pulled pupae whereas they dug more around trapped adults. Rescuing workers did not prioritize living individuals over dead ones or intact workers over injured ones indicating that trapped individuals were recognized chemically rather than by their morphology or behavior. Finally, workers prioritized foraging over rescuing, perhaps because fewer workers specialize in rescue behavior than in foraging. Our analysis indeed revealed that fewer workers both foraged and rescued trapped workers than expected by chance. In conclusion, ants that rescue others exhibit a complex set of behaviors, with varying attention and specific behaviors targeted at different individuals, perhaps according to the colony’s needs. Our study is important for emphasizing a relatively neglected aspect of sociality (rescue of group members) and demonstrates that the attentions of rescues differ based on the trapped nestmate’s life stage.

Abstract
Phenotypic integration can be defined as the patterns and strength of the covariances between traits in an organism. The pace of life syndrome (POLS) hypothesis provides a testable case of phenotypic integration as it predicts that traits that mediate the trade-off between current and future reproduction should have coevolved with the slow-fast life-history continuum and may thus covary across individuals of a population. Although the POLS hypothesis has received increasing attention over the last decade, there is a need for investigating whether POLS are sex-specific and whether ornamental traits can be included within the POLS framework. We used 9 years of data to describe the integration patterns of ornamental coloration, personality, morphology, and life history in blue tits (Cyanistes caeruleus) and whether they differed between males and females. With that aim, we fitted multivariate mixed models separating the among- from the within-individual covariances. We found that the overall integration between the studied traits was weak, but our results suggested some sex-specific covariances at the among- and within-individual levels. Finally, using structural equation models (SEM), we tested for the presence of trait modules (i.e., covariances between traits involved in the same biological function) within each sex. SEMs suggested the presence of a morphological module but no modules for coloration or behavioral traits. Also, results obtained from the SEM did not support the POLS hypothesis. Overall, this work highlights the importance of considering sex when studying phenotypic integration and the relevance of SEM to test POLS hypothesis.
Practitioner Understandings of Older Victims of Abuse and Their Perpetrators: Not Ideal Enough?
Authors: Bows Hannah , Bromley Paige , Walklate Sandra 
Published: October 2023

Abstract
This article reports data from interviews with 66 professionals working across safeguarding, health, criminal justice and specialist domestic abuse services exploring their views about older victims’ experiences of domestic abuse. The findings reveal that older victims, despite embodying many of the criteria of Christie’s ideal victim, are not ideal enough as they fail to conform to the stereotype of the young, female victim of intimate-partner abuse. Similarly, their perpetrators, whether older partners or younger sons/other family members, fall short of the necessary criteria to be seen as legitimate offenders—they are not quite ideal—meaning domestic abuse against older adults is frequently repackaged as a health issue, with significant implications for professional practice.
