Research on human mental disorders has started exploring the relationship between human facial expression recognition (FER) and symptoms of mental disorders because cases in FER are similar to symptoms in psychiatric disease. With the tremendous success of machine learning and deep learning, various models and architecture of these techniques are being leveraged to achieve better performance. The purpose of this work is to undertake a review of the most recent work on automatic facial emotion recognition (FER) using deep learning. We emphasize these contributions from the deep learning architecture and facial databases and the researchers’ progress by comparing the recommended technique with the findings produced. The study found that facial expression recognition based on cognitive internet of things (CIoT) in psychiatry disease did not yet exist, so it became a big opportunity to develop this research in the future. It can be concluded that this research can assist scholars by examining previous works and providing insights to improve this field and can be used as recommendations for psychiatric disease.

Impacts of climate change have received extensive attention, especially for the semi-arid regions. Raknamo reservoir is located at Kupang Regency, a semi-arid area with significant differences in rainy duration (3–4 months) and dry seasons (8–9 months). This preliminary study aimed to identify the recent factors that caused the delays in initial filling of Raknamo reservoir, which may be affected by climate change. There are three rainfall stations observed surrounding Raknamo watershed, namely Camplong, Naibonat and Raknamo. Direct comparisons were made of rainfall data for 33 years (1986-2019) daily. The climatology station Lasiana was used for climatological data with a data length of 33 years (1986-2019). This research used a qualitative approach, runoff was analyzed using regression analysis. The results showed that factors such as temperature (T), potential evapotranspiration (ETo), and rainfall (R) affected the availability of initial filling in the Raknamo reservoir. The amount of rainfall intensity that is not achieved in one period to fill the reservoir has resulted in the Raknamo reservoir utilization not being optimized.

Lithium extraction from geothermal brines has recently become a strong interest due to the large volume of lithium resources in over 2000 geothermal wells and hot springs worldwide. This article discusses the adsorption behavior of lithium contained in local geothermal brine water originating from the Ciseeng geothermal field in Bogor Regency, West Java Province of Indonesia, by Amberlite IR-120 Na resin. The lithium uptake and the selectivity of lithium adsorption by Amberlite IR 120 Na resin towards alkaline and alkaline earth elements contained in the geothermal brine samples, the equilibrium behavior, and adsorption kinetics were studied. The experimental results show that lithium adsorption increased by the increase in contact time of brine water and Amberlite IR 120 in 4-day continuous adsorption and reached a maximum level at day-3 to 0.0356 mmol/g Li. Li adsorption decreased after day-3, indicating that the Li adsorption had reached an equilibrium state at day-3. The highest adsorption recovery during 4-day continuous adsorption is exhibited by K, followed by Li, Na, Ca, and Mg. Considering a low adsorption percentage of Li (maximum 36.6%) but still higher than that of Ca, Mg, and Na, the adsorption parameters are still to be improved. Linear fitting of the experimental data on the four different isotherm adsorption models indicated that the lithium adsorption from Ciseeng brine fit mostly with Freundlich and Temkin model with an adsorption capacity of the Amberlite IR 120 of 0.051 mg/g. Based on the linear fitting procedure of the experimental data to four different kinetics models, the lithium adsorption from Ciseeng brine onto Amberlite resin follows the Elovich kinetic model (R2 = 0.986), which indicates the dominant chemisorption mechanism in the lithium adsorption process.

Sustainability and functioning of silvopastoral ecosystems are being threatened by the forecasted warmer and drier environments in the Mediterranean region. Scattered trees of these ecosystems could potentially mitigate the impact of climate change on herbaceous plant community but this issue has not yet tested experimentally. We carried out a field manipulative experiment of increased temperature (+2-3 ?) using Open Top Chambers and rainfall reduction (30%) through rain-exclusion shelters to evaluate how net primary productivity and digestibility respond to climate change over three consecutive years, and to test whether scattered trees could buffer the effects of higher aridity in Mediterranean dehesas. First, we observed that herbaceous communities located beneath tree canopy were less productive (351 g/m(2)) than in open grassland (493 g/m2) but had a higher digestibility (44% and 41%, respectively), likely promoted by tree shade and the higher soil fertility of this habitat. Second, both habitats responded similarly to climate change in terms of net primary productivity, with a 33% increase under warming and a 13% decrease under reduced rainfall. In contrast, biomass digestibility decreased under increased temperatures (-7.5%), since warming enhanced the fiber and lignin content and decreased the crude protein content of aerial biomass. This warming-induced effect on biomass digestibility only occurred in open grasslands, suggesting a buffering role of trees in mitigating the impact of climate change. Third, warming did not only affect these ecosystem processes in a direct way but also indirectly via changes in plant functional composition. Our findings suggest that climate change will alter both the quantity and quality of pasture production, with expected warmer conditions increasing net primary productivity but at the expense of reducing digestibility. This negative effect of warming on digestibility might be mitigated by scattered trees, highlighting the im

Stiff diagrams arc a multivariate method of analysis used to describe the chemical state of ground water. The use of Stiff diagrams to describe multiconstituent contamination sites, such as landfills, has distinct advantages over single constituent analyses. Problems associated with traditional Stiff diagram analyses, such as diagram attentuation, can be addressed by allowing the scale of the diagram to vary with the ionic strength of the analyzed sample. The use of these sliding scale Stiff diagrams reveals the chemical slate of the ground water over wide ranges of constituent concentrations and thus allows for sensitive and sophisticated depictions of complicated contamination sites in a fashion that is extremely difficult to replicate with single constituent analyses. This approach has possible applications for understanding and tracing the mixing and chemical changes in uncontaminated settings. Copyright © 1995, Wiley Blackwell. All rights reserved

Molasses has a high sugar content and potentially good to be used as a fermentation substrate in the production of ethanol. The main purpose of this study is to compared the ethanol yield between free and immobilized on calcium alginate as the agent of fermentation. The fermentation of molasses was carried out directly using yeast isolate K2 which was free and immobilized on calcium alginate. Isolate K2 was tested physiologically first to determine the character of its tolerance to NaCl, pH, and molasses. The physiological character of isolate K2 showed its ability to grow at the limit of 12% NaCl, pH 3-6, and 25% molasses concentration at 30°C. The highest ethanol content was 1.96% from 25% molasses concentration with 24 hours fermentation using immobilized K2 isolate while the lowest ethanol content was 0.42% from 24 hours fermentation time using free yeast. Substantially, it can be concluded that the immobilization of K2 isolate in calcium alginate has the potential to increase the production of ethanol from molasses.

作者： Bambang Wicaksono Ari Siswanto Susilo Kusdiwanggo Widya Fransiska Febriati Anwar Doctoral student Postgraduate Program Faculty of Engineering Sriwijaya University Jl. Palembang Prabumulih Km. 32 Inderalaya (OI Department of Architecture Faculty of Engineering Sriwijaya University Jalan Srijaya Negara Bukit Lama Ilir Barat I Palembang Sumatera Selatan 30128 Department of Architecture Faculty of Engineering Brawijaya University Mayjen Haryono Street Number 167 Malang Jawa Timur 65145

The development of the city in the modern era has had an impact on the culture of people living in the riverside. The river-oriented settlement culture is transformed into a land-based settlement culture. In this development, changes in the form of a settlement environment depend on the position of environmental elements in cultural systems such as nature, man, society, shells, and network. Changes in the form of environment affect the elements of the settlement. Some of them are repaired in building structures but material changes and others change following the development of the settlement orientation process. These changes undermine the identity, character, and potential of river architecture and settled cultures that were originally in harmony with river life. The purpose of this study was to explore the incidence and explanation of changes in the settlement elements in the Musi River and the architectural aspects of the house and residential type through a qualitative approach. Data collection is done qualitatively by using data collecting technique that is field observation, depth interview, and literature study. The analytical technique used is through qualitative approach of case study with a combination of strategies that identify elements of rural community settlements with triangulation. This study found the change of the settlement elements of the Musi River Palembang River from the river-oriented to the land-oriented. This study concludes that changes in the architecture and building system of river settlements that include changes in the orientation of buildings to rivers, the addition of space under the stilts, material changes, changes in the function of house space, and changes in river environmental infrastructure caused by the influence and development of land-oriented culture settlements, based on the elements of settlement on the banks of the River Musi Palembang.
