Community-led Innovations and Actions in Response to the Covid-19 Pandemic
Authors: Price Roz
Published: October 2022

Community engagement and community-led approaches have been considered a fundamental component of past pandemics, such as Ebola, and the same has been observed in the response to the Covid-19 pandemic, especially for reaching the most vulnerable. There is a large and growing literature base on community-led innovations in general, to which literature reflecting on Covid-19 responses is increasingly contributing to. This rapid literature review draws on a range of academic and NGO sources. First, Section 2 briefly explores what is meant by “community-led innovations”, as community-led is a loosely defined term that can take on a variety of meanings. Section 3 provides some examples of community-led innovations and actions from across a variety of contexts, including high-, middle- and low-income countries. Given the scale and scope of the subject, these only provide a small snapshot of community-led initiatives that have taken place in response to the Covid-19 crisis. Section 4 summarises the key common features and trends across examples. Section 5 summarises some general lessons and success factors identified in the examples and literature, building on the findings from Section 4.

Published: October 2022

Colorectal cancer is one of the most frequently diagnosed malignant tumors in men and women, which is a highly heterogeneous group of neoplasms consisting of subclasses with different molecular and clinical characteristics, and, as a consequence, patients with different types of tumors require different treatment protocols. Among the predictive factors of treatment response in patients with metastatic colorectal cancer, the most studied are the genes of the RAS family (KRAS, NRAS). Determination of RAS status is the first step in individual selection of drug therapy in patients with metastatic colorectal cancer. Patients with certain mutations in KRAS and NRAS genes are resistant to anti-EGFR therapy and have a lower median survival than WT (wild type) genotypes, indicating a negative prognosis in the presence of mutations.

Published: October 2022

Rats are attractive for various kinds of experiments aimed at studying the effect of substances on metabolism and other components of homeostasis. The use of biologically active substances of natural origin offers great opportunities for modulation of physiological processes in the body, increases the body's resistance, facilitates the clinical course of many environmentally caused diseases and has virtually no negative side effects. Purpose of the study: to study the peculiarities of postnatal physical development of the offspring of rats receiving intragastric aqueous plant extracts as an additional load. The experiment was carried out on sexually mature rats (50 females and 15 males), which were divided into 5 groups of 13 rats each. The groups received various compositions of aqueous plant extracts daily for 30 days at a dose of 30 mg/100 g of animal body weight. The animals were then mated, and the offspring were obtained and subjected to examination. Conclusion: loading rats with aqueous plant extracts promotes intensification of the postnatal physical development of the offspring, and the greatest efficiency is observed when using a mixture of aqueous extracts of Centella asiatica and Ginkgo biloba, rather than when using them separately.

Published: October 2022

The aim of this study is to examine if differentiated instruction benefits the mathematical thinking process of gifted and talented students in Malaysia. Differentiated instruction is a student-centered technique in which instructors act as facilitators. It is doubtful, however, if differentiated instruction has a beneficial effect on the overall process of mathematical thinking. A disciplined approach to learning mathematics is deemed essential. In this study, a questionnaire was designed to assess students' motivation towards learning using differentiated instruction in mathematics, and a mathematics test was devised to assess students' mathematical thinking process. The study included 400 students who were identified as gifted and talented students; the data were analyzed using the SPSS software. The results suggest that statistically differentiated instruction has a significant effect on gifted and talented students' mathematical thinking processes. However, additional research is needed to discover which activities directly impact students' mathematical thinking processes positively and which should be avoided.

Published: October 2022

Increased coastal human intervention and climate change are leading to rapid changes in coastal areas and often causing catastrophic damage to resident populations. The ShorelineS model was introduced, which can explain drastic beach changes were simulated. According to the modeling results, the installation of Gungchon Port caused rapid sedimentation in the south of the port. It was reviewed that the erosion and sedimentation tendency of the beach is changed after the installation breakwater in front of the beach, the erosion in the central part of the beach was somewhat suppressed, and the beach was deposited in the shape of tombolo on the back of the beach. The installation of artificial structures dramatically changes the equilibrium state of the beach and increases the erosion of the direct wave near the structure. The ShorelineS model was the advantage of being able to properly reproduce changes in the coastline by inputting relatively simplified environment and beach information and to quickly predict after installation of artificial structures. The reallity, coastline changes due to various causes, so follow-up studies are needed to predict and effectively respond to this through an advanced model that reflects various conditions.

Published: October 2022

Utilizing clean energy derived from photoelectrocatalytic reactions is expected to be an excellent choice to fundamentally solve the problem of the human energy crisis. Photoelectrochemical (PEC) cell can effectively promote charge separation and improve solar energy conversion efficiency since it combines the advantages of photocatalysis and electrocatalysis. However, the hole transfer and subsequent oxidation reaction in the PEC process are slow, resulting in the rapid recombination of photogenerated electron-hole pairs and low PEC performance. The half-oxidation reaction involving photogenerated holes is the bottleneck of PEC water splitting. Therefore, hole modulation has been an important research area in the field of catalysis. However, compared with electron modulation, research on hole modulation is limited and still faces great challenges. It is therefore of great significance to develop effective modulation strategies for photogenerated holes. This review summarizes the hole modulation strategies developed in the last five years, including hole sacrificial agents, nanostructural modification, heterostructure construction and cocatalyst modification. Hole modulation dynamics studies, such as transient absorption spectroscopy, time-resolved photoluminescence spectroscopy, transient photovoltage and scanning electrochemical microscopy, are also summarized. Moreover, relevant conclusions and an outlook are proposed.

Authors: Osinubi Tolulope T. , Ajide Folorunsho M.
Published: October 2022

Purpose ― In this study, we investigate the impact of foreign direct investment (FDI) on economic complexity in MINT and BRICS countries.
Methodology ― Data on economic complexity from MIT’s Observatory of Economic Complexity and data on FDI and other determinants of economic complexity are sourced from World Development indicators which spanned between 1991 and 2020. The countries are divided into three categories: All countries pooled together, MINT and BRICS countries. We employ panel co-integrating regression.
Findings ― Findings based on panel co-integration regression show that foreign direct investment positively impacts economic complexity in all the countries and MINT countries, while its impact is negative in BRICS countries.
Originality ― This study adds value to the literature by scrutinizing the nexus between FDI and economic complexity in the context of emerging economies and employs the panel co-integration technique for robust analysis. The study's findings shed light on the need for governments in developing countries to implement appropriate policies encouraging FDI inflows into their respective countries. Contributing to the host country's economic complexity, FDI inflows should be focused on highly technical investment and, most importantly, should be selective to enhance the development of priority sectors. An investment promotion policy may be required to encourage foreign investment in the host country.

Published: October 2022

Currently, ecotourism has become an important industry because of its rapid development. Many tourism practices have adverse environmental impacts. Due to the increasingly destructive commercialization of the natural resources on which we depend, there are several negative impacts. Aek Nauli Research Forest (ANRF), with an area of 1,900 hectares, is one of the natural tourist destinations around the Lake Toba Tourism area managed by the Aek Nauli Research Institute for Environmental and Forestry Development (BP2LHK). The location of the study is in Girsang District, Sipangan Bolon, Simalungun Regency, North Sumatera Province. The tourist objects are natural panorama, elephant conservation education tour, and siamang animal ape park. On average, the number of visitors of ANRF on regular days is 100-300 visitors/day and on holidays reaches 300-1,700 visitors/day. The increase in the number of visitors is perceived to have an impact on environmental sustainability. This study aims to determine the capacity of the ANRF ecotourism area to accommodate the number of tourists per day simultaneously. The method used is the effective carrying capacity by Cifuentes method based on several stages of analysis, namely Physical Capacity (PCC), Real Capacity (RCC), Management Capacity (MC), and Effective Capacity (ECC). The environmental carrying capacity analysis results showed that the PCC, RCC, ECC were 26,106 visitors/day, 3,007 visitors/day, 2,505 visitors/day respectively while MC was 0.83. This value can be used to advise managers to limit visitors, particularly during peak season, in order to preserve objects and the quality of visits.

Published: October 2022

The floristic study is necessary to understand the present diversity status and conservation of forest biodiversity. It has been realized that the study of local or regional flora is of much more significance than those covering big areas because explorations can be carried out intensively in small areas with damaging consequences. Understanding species diversity and distribution patterns are important to evaluate the complexity and resources of these forests. In the present study, the medicinal floristic diversity of Pilavakkal dam Foothills of the Western Ghats comprised of 127 species belonging to 42 families and 100 genera. Fabaceae, Malvaceae and Lamiaceae were dominant families with 23, 11 and 10 species, respectively. The total number of species includes 55 herbs, 23 shrubs, 37 trees and 12 climbers. Totally 127 important medicinal plant species are recorded in Pilavakkal dam Foot Slopes of Western Ghats. Psydrax dicoccos is vulnerable in this list, 27 plants species are Least Concern and Mangifera indica comes under the Data Deficient and 98 plants species evaluated are not categorized by IUCN. This study provides basic information about the medicinal flora and conservation status of the Pilavakkal dam Foothills of Western Ghats. It would also be helpful for the identification of flora and to derive conservation policies and make sustainable use of plant resources.

Published: October 2022

Mapping and prediction of inundated areas is increasingly important for climate change adaptation and emergency preparedness. Flood forecasting tools and flood risk models have to be compared to observed flooding patterns for training, calibration, validation and benchmarking. At regional to continental scale, satellite earth observation is the established method for surface water extent (SWE) mapping and several operational global-scale data products are available. However, the spatial resolution of satellite-derived SWE maps remains a limiting factor, especially in low-lying areas with complex hydrography, such as Denmark. We collected thermal imagery using an unmanned airborne system (UAS) for three areas in Denmark shortly after major flooding events. We combined the thermal imagery with an airborne lidar-derived high-resolution digital surface model of the country to retrieve high-resolution (40 cm) SWE maps. The resulting SWE maps were compared to low-resolution SWE maps derived from satellite earth observation (EO). We conclude that UAS have significant potential for SWE mapping at intermediate scales, can bridge the scale gap between ground observations and satellite EO and can be used to benchmark and validate SWE mapping products derived from satellite EO as well as models predicting inundation.
Some Estimators and their Properties Following Kabirian-based Optinalysis
Authors: Abdullahi Kabir Bindawa
Published: October 2022

Good estimators are characterized as robust, unbiased, efficient, and consistent. However, the commonly used estimators are weak or lack one or more of these properties. In this article, eight (8) estimators for statistical and geometrical estimations of symmetry/asymmetry, similarity/dissimilarity, identity/unidentity, and feature transformation were proposed following Kabirian-based optinalysis and other operations. The proposed estimators are characterized as invariant (robust) under scaling, location shift, and rotation or reflection. A computing code was written in python language for each of the proposed estimators so that peers can have working codes for application and performance evaluation.
R-Curve Behavior of Polyhedral Oligomeric Silsesquioxane (POSS)–Epoxy Nanocomposites
Authors: Mishra Kunal , Singh Raman
Published: October 2022

Polyhedral oligomeric silsesquioxane (POSS) is a suitable nanoscale reinforcement for thermosetting polymers, such as epoxy resin systems in order to modify its mechanical, thermal, and chemical properties. The inclusion of POSS in the epoxy resin at higher loading (greater than 1 wt.%), however, introduces the ductility during the fracture behavior of these nanocomposites. Consequently, the J-integral is used to quantify the fracture behavior of these materials and characterize the crack growth resistance curve against stable crack growth. A range of nanocomposites is prepared by adding 0.5, 1, 3, 5, and 8 wt.% of glycidyl POSS into DGEBF epoxy resin cured with an amine-based curing agent. From the fracture toughness experiment the load-displacement result confirms that when the POSS reinforcement is greater than 1 wt.%, the fracture behavior of the nanocomposite changes from brittle to ductile. For both brittle and ductile nanocomposites, the addition of POSS molecules improves the crack initiation toughness. The development of POSS–POSS compliant domains are reported previously, is attributed for this change in the failure behavior. The fractured images of POSS–epoxy nanocomposites, obtained using scanning electron microscopy, show that the increase in fracture resistance at higher values of POSS loading occurs due to the extensive shear yielding. Meanwhile, the increased fracture toughness at lower values of POSS loading occurs due to crack pinning and crack deflection.

Published: October 2022

The growth and development of food delivery service applications in Indonesia has occurred very rapidly in the last 4 years. Digitization in the food and beverage sector in Indonesia is supported by the growth and development of food delivery service applications, namely Gofood and Grabfood, which focus on service providers selling, ordering and delivering food and beverages from places of sale to consumers. Gofood and Grabfood are currently the two largest food delivery application services in Indonesia with quite fierce competition between the two. In the midst of the progress of these two food delivery services, a new phenomenon has emerged where there are new players entering the competition in the food delivery service industry in Indonesia, namely from one of the largest e-commerce platforms in Indonesia and Southeast Asia called Shopee, namely Shopee Food. The emergence of ShopeeFood makes the competition in the food delivery service application industry increasingly tight in Indonesia. Application users have more choices to use the application and choose to be satisfied or dissatisfied with the application for the services provided. Among this fairly tight competition, therefore, identification is needed to find out what factors can increase user satisfaction in Indonesia with food delivery service applications.
Medios LGBT+ en internet: experiencias de comunicación e información en México
Authors: Olmedo Neri Raúl
Published: October 2022

Two digital LGBT+ media in Mexico are analyzed to understand the implications of their operation and their articulation with the informational and social needs of sex-gender populations. It starts from the communicational perspective to conceptualize these projects as exercises in technological appropriation but highlighting their empirical intersections with other analytical frameworks. Through the method of systematizing the experience, the trajectories of ANODIS and Seis Franjas Mx have been recovered; through semi-structured interviews conducted with their co-founders in February 2022, the reasons, horizons and challenges that these projects have faced are analyzed. The results show that the lack of LGBT+ content and representations in the media motivate the creation of these projects, which articulate a sense of collaboration and sociality with other users belonging to sex-gender communities. In addition, the people participating in these projects are part of the LGBT+ populations, becoming them producers and consumers of information that claim the gender-identity dimension in the content. Likewise, these initiatives are specified in the youth stage of their co-founders, which refers to rethinking the role of LGBT+ youth in the new forms of activism and socialization mediated by Internet. Finally, given the progressive formation of this area of ​​knowledge and the lack of consensus on its definition, it is proposed to name this interdisciplinary field of study as LGBT+ Communicational Studies, to show an epistemological perspective from communication and a Latin American ontological position.

A spoon is a tool to be used instead of a hand in reaching for something. It was rounded, hollow, and round. Most of the use of spoons apart from home is also used extensively by food merchants. Tablespoons among the traders were used interchangeably by the buyers. The cleanliness of eating utensils is an important factor and has an impact on the quality of food. Less hygenic washing may include bacteria such as e. coli, vibrio, clostridium, salmonella, staphylococktail, bacillius sp. for that matter, equipment laundering is essential. A study of the problem will prevent the spread of various viruses and bacteria. One is by making an instrument that can be used to sterilize the tablespoon by using a uv exposure. According to tests taken at upt the ponorogo area health lab, feeding utensils are said to be sterile ata minimum of 5 minutes of the uv fishing and broadcasting process.

We applied quantitative methods to previously published biostratigraphic data from the Baltimore Canyon Trough (offshore of the Mid-Atlantic U.S.A.) to provide an improved chronostratigraphic framework for Cretaceous sequences. Here, we successfully used graphic correlation of 228 planktonic foraminifera, nannofossil, and palynological events spanning 22 wells to define assemblage and interval zones as well as major paleoenvironmental changes in the Dawson Canyon, Logan Canyon (three sequences), and Missisauga Formations (two sequences, undifferentiated here). Ranking and scaling techniques were not successful because of the of the limited number of usable biostratigraphic markers. The ages of the sequences previously identified using well logs and seismic profiles were temporally constrained based on chronostratigraphically significant biostratigraphic markers that we identified: the late Cenomanian to Turonian DCx sequence (Rotalipora cushmani and Thalmanninella greenhornensis); the early Cenomanian LC1 sequence; the middle and late Albian LC2 sequence (Braarudosphaera africana, Planomalina buxtorfi, and Spinidinium vestitum); the late Aptian LC3 sequence (Cyclonephelium tabulatum); and the early Aptian to Barremian Missisauga sequences (Aptea anaphrissa, Pseudoceratium pelliferum, and Muderongia simplex). These five biostratigraphic associations are correlated with six prominent seismic reflectors and sequence boundaries that can be traced across the basin. Duration of hiatuses associated with these sequence boundaries are uncertain, though our Monte Carlo analysis allows extraction of age estimates from broad and sometimes contradictory ranges and suggests correlation of hiatuses with global sea-level falls. Together, these seismic and biostratigraphic interpretations can be applied (1) to evaluate reservoir continuity and the viability of offshore carbon storage reservoirs in the Baltimore Canyon Trough, (2) to better define the tectonostratigraphic evolution of the basin, and (3) to contribute to the understanding of regional and global variations in Cretaceous sea level.

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 206267, “Benchmarking and Field Testing of the Distributed Quasi-Newton Derivative-Free Optimization Method for Field Development Optimization,” by Faruk Alpak, SPE, Yixuan Wang, SPE, and Guohua Gao, SPE, Shell, et al. The paper has not been peer reviewed.

Recently, a novel distributed quasi-Newton (DQN) derivative-free optimization (DFO) method was developed for generic reservoir-performance optimization problems, including well-location optimization (WLO) and well-control optimization (WCO). DQN is designed to locate multiple local optima of highly nonlinear optimization problems effectively. However, its performance has been neither validated by realistic applications nor compared with other DFO methods. Field-testing results reinforce the auspicious computational attributes of DQN.

Background

An optimization problem is posed as the minimization or maximization of an objective function by modifying the control variables (x) within a search domain. The objective function is a highly nonlinear function of x and may have multiple local optima. In this paper, the objective function is assumed to be twice differentiable.

DFO methods can be classified into local search methods and global search methods. In the complete paper, the authors’ goal is to locate multiple local optima of the objective function. Their focus is on local search DFO optimization methods, which include direct search methods and model-based methods.

Current DFO methods reviewed in the complete paper have a common feature: Only one best approximation to the solution is updated in each iteration, and only one optimal solution is identified in the last iteration. Therefore, they are referred to as single-thread DFO methods. They do not represent an efficient approach because simulation results obtained by one optimization task starting from one initial guess are not shared with other optimization tasks that start from different initial guesses. The distributed Gauss-Newton method and the DQN method benchmarked in the paper are referred to as multiple-thread optimization methods.

The authors have integrated DQN into a versatile field-development optimization platform designed specifically for iterative work flows enabled through distributed-parallel flow simulations.
Pyrolysis of Macroalga Macrocystis Pyrifera for Production of Green Carbon-Negative Hydrogen

Published: October 2022

Stringent emission norms worldwide have provided an impetus to explore alternative sustainable fuels that are carbon neutral. Hydrogen is touted as one of the potential fuels that aid decarbonization. Biomass, especially the ones that do not compete with the food needs are considered promising feedstock for hydrogen production by thermal conversion. In the current study, the performance of the macroalga Macrocystis pyrifera in the thermal conversion through pyrolysis as a potential biomass for hydrogen production was examined.

The macroalga Macrocystis pyrifera is a giant brown seaweed commonly found in the Pacific Rim. It is characterized by its fast-growing ability and photosynthetic metabolism that generates carbon sources from atmospheric CO2. This alga is a potential biomass to be applied in bioenergy with carbon capture and storage (BECCS), which enables carbon-negative biofuels to avoid greenhouse emissions from biomass processing and use.

Pyrolysis is a conventional method for the thermal conversion of biomass with low moisture into potential fuels. This process consists of decomposing the biomass into charcoal, light hydrocarbons, and non-condensable gases by the action of high temperatures (350-600°C) and the atmospheric pressure. The pyrolysis of the macroalga is applied to a process simulation in Aspen plus V12 with an optimization achieved by multiple sensitivity analyses. Additionally, to upgrade the hydrogen production from a carbon-neutral biofuel to BECCS, a carbon capture unit by physical absorption with dimethyl ethers of polyethylene glycol (DEPG) is included using a hierarchy user model of the software.

The results showed a high sensitivity of the temperature. Additionally, a second reactor and a water gas shift unit were necessary to maximize the hydrogen production.

The temperature profile showed a maximum production of hydrogen at 500°C with the following reduction of its yield at higher temperature values due to the enhanced carbon monoxide production. Additionally, a second reactor operating under the same conditions as a gasifier and a water gas shift unit based on the Le Chatelier principle successfully increased the hydrogen production by 50%. Finally, a hydrogen yield of 2.06% was reached.

The study related to the thermal conversion of this alga is an opening to the study of the thermal conversion of biomass commonly found in desertic or semi-desertic climates such as halophytes or salicornia.
