Published: March 2021

Abstract
Based on the best track data set of tropical cyclones and ENSO index, the influence of two kinds of ENSO events on tropical cyclones in the Northwest Pacific Ocean is discussed based on the El Niño / La Niña event discrimination method recently issued by China Meteorological Administration. The results show that ENSO events have an important impact on the TC activity in the Northwest Pacific. The frequency of TC formation in La Niña year is more than that in El Niño year, and the duration and ACE of TC in El Niño year are greater than those in La Niña year. From the comparison of TC activities at different levels, the impact of ENSO events on high-level TC (STY and SuperTY) is greater than that of low-level TC. On the whole, the TC in the Northwest Pacific is greatly affected by the CP-ENSO event, and the high-level TC (SuperTY) is most affected by the EP-ENSO event. In terms of the origin location, the differences of the impact of the two ENSO events on TC origins of different levels are mainly reflected in the differences between the northern and southern South China Sea, and the differences between the southeast and Northwest Pacific.

Abstract
Birds keeping, especially songbirds, has been considered as one of the major drivers that lead to species extinction in Indonesia. The demand for songbirds either for songbird’s competition or to be enjoyed at home is considerably high, especially in Java. As the native Javan population has been depleted due to habitat conversion and excessive trapping, the supply of songbirds is provided by other islands in Indonesia such as Sumatera and Kalimantan. We conducted long term monitoring of songbird’s trade on Jambi. Data on bird’s trade was obtained by examining the transaction records from wholesalers from the period of 2016 – 2020. The results showed that there were shifting in species target especially after 2018 due to implementation of new regulation on protected species. However, the total number remains high. The trade comparison for the same period between trade records in 2016 and 2020 demonstrated the reduction in the number of species from around 32 species to 25 species, however, the total volume of traded birds is higher in 2020 which is 20.600 compare to 7.198 during the first sixth months. Considering the pandemic situation, the songbirds trade activities is seemingly not affected especially for the distribution chain from hunter to wholesalers.

Icing - Renewable Water Source and Resource
Authors: Narantsogt Nasanbayar 
Published: March 2021

Abstract
The icing phenomena occurs in Mongolia every winter, same places where groundwater overflow on ice on surface waterbed, create next ice sheet and create extended ice storage. This phenomenon is important parameters in hydrological cycle and surface water regime for semi-arid, cold regions. The highly continental, semi-arid and cold region has a high variability in river discharge depending on precipitation, with a general tendency towards decreasing water availability due to increasing air temperatures and thus rising potential evaporation. In this study considered understanding natural process of creating icing, due to keep water source as in ice form on surface in dry season. From March to May icing meltwater recharge groundwater and river flow while river is non-flow condition. Some year’s in April riverbed dry without ice in valley under highly mountains, but upper side is cold and water source is still in snow and ice form. Therefore, icing in river valley could recharge surface water by melting where is cold on top mountains river origin but under valley riverbed no snow, ice cover. In this paper written icing process code by MATLAB using energy change between water, air and ice. When we are promoting naturally ice storing or build icing then winter coldness creates ice storage thus artificially recharge surface water resources in dry season like April. The ice storage amount and simulation results shown that recharge groundwater in dry season is icing method one of the possibilities which creates and build huge ice storages in winter. That is new technology keep water in ice form through winter and recharge surface and groundwater in dry season.

Published: March 2021

Abstract
Herein, we investigate the mechanical and wetting properties of composites-based epoxy matrix reinforced zinc phosphate glass particles at different volume fractions. The investigated composites were characterized using X-ray diffraction and Fourier-transform infrared spectroscopy. In addition, the morphology of composite was performed using scanning electron microscope tool. Moreover, the wettability of the composite performed by measuring water contact angle and surface energy. Contact angle findings revealed that the incorporation of zinc phosphate glass has significantly decreased with increasing filler concentration, while the surface energy values increased with filler concentration allowing improvement of the zinc phosphate glass-polymer interface. Besides, the investigated composites display enhanced mechanical properties for Young’s modulus. In this study, the glass transition temperature has been determined using differential scanning calorimetry analysis which suggested that consolidated composites are significantly homogeneous and have good thermal stability.

Published: March 2021

Abstract
The present work was designed to synthesize a Chitosan (CS) - Cerium oxide (CeO2)nanobiosorbent and study the adsorption of Indigo Carmine. The adsorption equilibrium data were better fitted in the Freundlich isotherm model, indicating that adsorption is occurring on a heterogeneous surface in the multilayer pattern. Low pH values (3 and 4), low initial Indigo Carmine concentration (50 mg/L), high adsorbent concentration (500 mg/L) and relatively high temperatures (50 °C) exhibited the highest removal efficiency towards the examined dye. The pseudo-second order kinetic model described better the adsorption process;thus, it can be stated that chemisorption between the adsorbent and the adsorbate is occurring. According to the thermodynamic analysis, adsorption process is spontaneous, exothermic and more favorable at high temperatures. FTIR analysis confirmed the adsorption of the dye onto the CS/CeO2nanobiosorbent.

Published: March 2021

Abstract
Digital inclusion in the Ecuadorian amazon is known as a problem, which intensified with the pandemic. Since social distance is now the norm, we constructed a WiFi access point (WAP) scanner to map and analyze its data. We correlated it with ancillary geoinformation to observe its potential and limitations as a method for indirect data collection. Our result indicate that WAP correlate weakly but positively with nightlight, young population, accessibility to economical centres, and negatively with slope. Moreover, we differentiated vulnerability naming patters from Service Set Identifiers (SSDI) and differentiated the number of WAPs according to land cover for differentiate urban from rural areas. This output is now offering increasing applications to get updated rought estimates of internet activity and indirectly correlations to socio-economic conditions, technology practices, and opportunities for natural language processing. Therefore, we conclude that wardriving offer interesting opportunities for mapping social data but also concerns as an indirect data collection method.

Published: March 2021

Abstract
Several efforts have been made to understand nutrient ecology worldwide. However, Ca and Mg have received less attention, despite their function in important biological processes of plants, such us growth and photosynthesis. Few studies focus on fern nutrient ecology of foliar Ca and Mg. Moreover, none has investigated the variation of these elements along elevational gradients. Herein, we analysed if there were differences of the foliar Ca and Mg contents of six species of ferns along a tropical elevational gradient: Adiantum humile, Cyathea tortuosa, Cyclodium meniscioides, Danaea moritziana, Maxonia apiifolia, and Thelypteris biformata. We found significant differences at the interspecific and intraspecific level variation of foliar Ca and Mg contents at each elevation. In terms of the relationship between elevation and nutrient content, we found that two species showed contrasting trends of foliar Ca with elevation. Content of Ca decreased with elevation in Adiantum humile, while it increased in Maxonia apiifolia. Regarding Mg, it decreased with elevation in Adiantum humile, Thelypteris biformata and Maxonia apiifolia. However, these results were not statistically supported. An exhaustive sampling effort will provide insight on variation of foliar Ca and Mg along tropical elevation gradients and the factors influencing patterns of variation.

Published: March 2021

Abstract
The Cutuchi River Basin extends over the inter-Andean valley south of the Cotopaxi Volcano, in Ecuador. It flows through two provinces, Cotopaxi and Tungurahua, and its waters are extensively used to irrigate crops that provide food to the main cities in the country. Unfortunately, the basin receives untreated domestic and industrial discharges. The need for an environmental quality assessment of the river has been acknowledged over the years. The aim of this study is to gather information about water quality of the Cutuchi River through a historical bibliographic review. A total of 57 works published between 2007 and 2018 were found, including books, articles, thesis and project reports. Only 18 documents provided biological, physical, or chemical data linked to water quality. The data obtained through the literature review were compared with maximum thresholds from national and international regulations. Unfortunately, revised studies were scattered on time and randomly along the basin and did not provide robust information to evaluate the state of the water-system. Some contamination was detected significantly exceeding safety thresholds. More exhaustive studies along the basin are needed as a baseline to help the decision makers to design management plans and mitigate human impacts.

Authors: Hashiguchi H , Toda M , Chew W C , Hiratsuka M 
Published: March 2021

Abstract
We investigated the impact of ethnicity on the adaptability of forest resource management in Myanmar. Within Myanmar’s ethnically diverse population, extensive economically motivated internal migration has led to the forming new villages comprising people of different ethnicities. Conditions and problems encountered in these newly formed villages may differ from those in ancestral villages where customary rights prevail. We assessed the livelihood systems and cooperative behaviours of different ethnic groups within a study village. Our findings were as follows: 1) households’ ethnicities influenced their levels of dependence on different livelihood sources, namely Non-timber forest products (NTFPs) and field crops, and 2) cooperation among the villagers of different ethnicity was weak. To achieve successful and sustainable natural resource management in such region, the characteristics of different ethnic groups should be taken into account in community forest management plan.

When the static pressure is 1100N ∼ 1200N, the depth of the residual compressive stress layer reaches its maximum.
The Industry’s Perspective of Suitable Tasks for Human-Robot Collaboration in Assembly Manufacturing
Authors: Gustavsson Patrik , Syberfeldt Anna 
Published: March 2021

Abstract
Human-robot collaboration (HRC) is the concept of combining a human and a robot into the same production cell and utilize the benefits of both. This concept has existed for more than a decade, but there are still quite few implementations of HRC within the manufacturing industry. One reason for this is the lack of knowledge when it comes to suitable tasks for HRC. Current research studies on the topic are mainly based on theoretical reasoning and/or research experiments, and little is known about what the industry perceive as suitable tasks for HRC. Therefore, this paper aims to investigate this and find out what industrial actors thinks are the most value-adding tasks for a human and a robot to carry out together. An in-depth interview study is undertaken with two companies and shop-floor operators, production engineers and automation engineers are interviewed. The result of the study pinpoints a number of tasks that the companies thinks are beneficial for HRC, which can serve as a guideline for other manufacturing companies considering to implement HRC.
