Zeolite-templated Carbon Network: A Beta Zeolite Case Study

In this work, we report a preliminary study, based on molecular dynamics simulations, about 3D carbon nanotube networks that could be formed inside the beta zeolites. We investigated their structural stability and mechanical properties. Our results show that from all possible carbon nanotubes that can be embedded inside the channels of the beta zeolite, the one with chirality (6,0) is the most stable. Using the carbon nanotube (6,0), it is possible to build 3D structures with both all (higher density) and only partially (lower density) filled zeolite channels. Under tensile uniaxial force, the 3D low-density carbon nanotube networks are anisotropic and can be stretched along the direction in which all nanotubes are perpendicular up to 130% of strain without fracture. Also, the porosity and network stiffness can be tuned depending on the amount of carbon nanotubes filling the channels of the zeolites.
Dry Fish and Its Contribution Towards Food and Nutritional Security

ABSTRACT The match between dry fish supply and nutrient needs is vital to support the health and well-being of the increasing human population. The depleting fisheries resources also suggest a corrective measure to define accurately the amount and quality of nutrients supplied by dry fish. Dry fish is increasingly becoming a vital factor in providing high-quality proteins, healthy fats (including long-chain omega-3 fatty acids like eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)), and a unique source of essential nutrients such as iodine, zinc, copper, selenium, and calcium. Our knowledge on contribution of dry fish towards food and nutritional security is largely based on limited scattered data which is unsatisfactory. The aim of our work consequently to put together dry fish information all about nutrition and its safety aspects. We show that dry fish gives basic supplements of high bioavailability which are found in constraining sums in the eating regimen of developing countries. The review also assesses the economics and health risks associated with consumption of dry fish and consequently, the necessary measures and steps to reduce such risks in order to have a safer food for the consumers and profitability to fish farmers.
The Influence of O2 on the Enrichment and Activities of Acidophilic Fe(III) Reducing Bacteria

Abstract Microbiological Fe(III) reduction under oxic and acidic conditions in acid mine drainage (AMD)-impacted systems is surprising, given the greater energetic favorability of O2 reduction than Fe(III) reduction. A possible explanation for this observation is that the energetic favorability of Fe(III) reduction approaches that of O2 reduction at pH < ∼2. However, some microorganisms require O2 for optimal Fe(III) reduction, and the process has still been observed at pH ≥ 3.5 under oxic conditions. We set up acidophilic Fe(III) reducing enrichment cultures with and without O2. The time of initiation and extent of Fe(III) reduction in oxic and anoxic enrichments were identical, and Fe(III) reduction by the enrichment cultures occurred to similar extents with subsequent transfers of the cultures. Desulfosporosinus- and Clostridia-attributable phylotypes dominated the anoxic enrichment cultures and Alicyclobacillus- and Acidibacillus-attributable phylotypes dominated the oxic enrichment cultures. Our results indicate that while O2 does not impact Fe(III)-reducing activities, it does impact the types of organisms that can be enriched in its presence or absence. The ability of AMD-associated organisms to reduce Fe(III) under both oxic and anoxic conditions may allow them to adapt to fluctuating O2 levels that are encountered in AMD-impacted settings.
Critérios para indicação de espécies prioritárias para a restauração da vegetação de cerrado

Knowing the attributes of the most suitable species to overcome the obstacles in different environmental conditions is an important tool for ecological restoration. To evaluate the comparative performance of native Cerrado species being cultivated at an arboretum (Assis State Forest, Assis, SP, Brazil), we categorized 106 species by the following attributes: average annual increment in height and crown diameter, survival rates, frequency of herbivory, frost susceptibility and seed dispersal syndrome. The score of each attribute may vary from 1 to 3, and the value of a species for restoration was generated from the sum of the scores for the different attributes converted to the scale of 0 to 100. Analyzing the species altogether, survival was 70%, the average annual increment was 30 cm in height and 21 cm in crown diameter. Only 8% of the species showed high susceptibility to frost and 17% high frequency of herbivory. Eighteen species had scores above 80, being the first Annona crassiflora, Cecropia pachystachya, Enterolobium gummiferum, Plathymenia reticulata e Protium heptaphyllum. In this group are the species that gather the highest number of favorable attributes for the restoration of Cerrado vegetation. We generated two separate lists of ten species of higher value, one for the cerrado sensu stricto and the other for cerradão – the forest type of cerrado vegetation. We believe that using these species accelerates the recovery of vegetation structure and thus provide the restoration of ecological processes of ecosystems undergoing restoration. At the end of the list are species of low scores, which, if used, can lead to higher costs or delay in the recovery of structure and ecological processes of the ecosystem being restored.
Machine learning based identification of dominant controls on runoff dynamics

Hydrological models used for flood prediction in ungauged catchments are commonly fitted to regionally transferred data. The key issue of this procedure is to identify hydrologically similar catchments. Therefore, the dominant controls for the process of interest have to be known. In this study, we applied a new machine learning based approach to identify the catchment characteristics that can be used to identify the active processes controlling runoff dynamics. A random forest (RF) regressor has been trained to estimate the drainage velocity parameters of a geomorphologic instantaneous unit hydrograph (GIUH) in ungauged catchments, based on regionally available data. We analyzed the learning procedure of the algorithm and identified preferred donor catchments for each ungauged catchment. Based on the obtained machine learning results from catchment grouping, a classification scheme for drainage network characteristics has been derived. This classification scheme has been applied in a flood forecasting case study. The results demonstrate that the RF could be trained properly with the selected donor catchments to successfully estimate the required GIUH parameters. Moreover, our results showed that drainage network characteristics can be used to identify the influence of geomorphological dispersion on the dynamics of catchment response.
Recreational scuba diving in a groundwater ecosystem: Disturbance mechanisms, ecological impacts and stakeholder perceptions

Ecological damage by scuba divers has been extensively studied in marine ecosystems, particularly coral reefs, whereas the impacts on freshwater environments such as groundwater springs is unknown. In the Silfra groundwater fissure in Iceland, a vast increase in diver entries has occurred during the last decade, prompting concerns over potential ecosystem impacts and visitor carrying capacity. Here, a mixed-method approach was used to assess the impacts of scuba diving in Silfra. (a) Divers were recorded under water to observe the mechanisms of diver-related disturbances, (b) benthic material was collected along transects in Silfra and the undisturbed fissure Flosagja to compare biofilm biomass and zoobenthic communities between and within fissures, and (c) the perceptions and experiences of stakeholders surrounding the dive tourism in Silfra were explored. Underwater observations showed that 91.4% of the divers caused at least a single disturbance, resulting in biofilm detachments and/or sediment stirring. Diver fins caused the most frequent disturbances, predominantly through fin-generated currents but also by directly contacting the substrate. Benthic biofilm biomass was lower in Silfra than Flosagja and exhibited a negative correlation with dive-use. Some disturbance-tolerant zoobenthic groups exhibited moderate to strong correlations with dive-use. All stakeholders had negative perceptions towards increasing diver entries, but although entry limitation could improve tourism quality, disturbance might only minimally be reduced as springs like Silfra may be particularly sensitive. Springs are characteristically stable and uniform environments that can be vulnerable to disturbance. Their use for scuba diving should be carefully managed through a holistic approach and an active collaboration between all stakeholders.

High heritability and high genetic advance for 100-seed weight. average fruit weight, yield/vine arid number of seeds/fruit were the most reliable traits' for selection.
Early syn-rift igneous dike patterns, northern Kenya Rift (Turkana, Kenya): Implications for local and regional stresses, tectonics, and magma-structure interactions

Four areas (Loriu, Lojamei, Muranachok-Muruangapoi, Kamutile Hills) of well-developed Miocene-age dikes in the northern Kenya Rift (Turkana, Kenya) have been identified from fieldwork and satellite images; in total, >3500 dikes were mapped. Three areas display NNW-SSE– to N-S–oriented dike swarms, with straight, radial, and concentric patterns in zones <15 km long, and indicate NNW-SSE to N-S regional maximum horizontal principal stress (SHmax) directions in the early to middle Miocene. Individual dikes are typically <2 m wide and tens to hundreds of meters long and have accommodated <2% extension. In places (Loriu, Lojamei, Lokhone high), dikes trend at a high angle to the rift trend, suggesting some local influence (e.g., overpressured magma chamber, cracked lid–style dike intrusions over a sill or laccolith, preexisting fabric in basement) on orientation, in addition to the influence from regional stresses. Only a minor influence by basement fabrics is seen on dike orientation. The early- to middle-Miocene dikes and extrusive activity ended a long phase (up to 25 m.y.) of amagmatic half-graben development in central Kenya and southern Turkana, which lay on the southern edge of the early (Eocene–Oligocene) plume activity. The Miocene dike sets and extension on major border faults in Turkana contrast with larger, more extensive arrays of dikes in evolved systems in the Main Ethiopian Rift that are critical for accommodating crustal extension. By the Pliocene–Holocene, magmatism and intrusion along dikes had become more important for accommodating extension, and the tectonic characteristics began to resemble those of rift basins elsewhere in the eastern branch of the East African Rift.
A new confinement scheme for reinforced concrete columns using stainless steel or glass fiber reinforced plastic

A new lateral confining method is proposed for reinforced concrete columns in this study. The new scheme incorporates additional lateral confinements that are placed outside conventional lateral reinforcements within cross section of a column. Stainless steel wires or glass fiber reinforced plastic (GFRP) rings have been employed as the additional confinement. A total of seven reinforced concrete column specimens have been tested to validate the proposed new scheme. Primary parameters in the test are vertical spacing and volumetric ratio of the additional confinements amongst others. Lateral hysteretic response shows that specimens with the newly proposed scheme exhibit no strength degradation up to 6% of drift ratio, the specimen without such scheme displays somewhat sudden degradation at 5% of drift ratio. Experimental results also indicate that displacement ductility and energy dissipation of specimens confined by the additional confinements are greater than those of specimen without such confinements. Margin of safety with reference to the code‐specified ductility is 1.6, 2.2, and 2.1 for specimen with no confinements, stainless steel wires, and GFRP rings, respectively. In addition, energy dissipation ability reveals that specimens with the confinements show up to 50% higher than the specimen without confinements. In all, experimental observation confirms that the present approach is promising to provide an additional confinement and ductility. It is thus expected that the suggested scheme can be applied to reinforced concrete columns and be particularly effective for those members with relatively large vertical spacing of conventional lateral reinforcements.
Greenhouse Gas Emissions in Norwegian Agriculture: The Regional and Structural Dimension

This paper studies the hypothesis that farm structure and the regional distribution of agricultural activity themselves have a significant impact on greenhouse gas (GHG) emissions from agriculture. Applying a dynamic model for the Norwegian agricultural sector covering the entire farm population, the model results support the hypothesis. Even without mitigation options, GHG emissions decline by 1.4 per cent if agriculture becomes regionally concentrated and increase by 1.5 per cent if a policy that favors a small-scale farm structure is put in place. Adding a carbon tax to a policy that leads to regional concentration, may help to reconcile competing policy objectives. A switch from animal production to crop production, and an extensification of animal production keeps a large resource base across the country while cutting GHG emissions.
Political Ideology and Executive Functioning: The Effect of Conservatism and Liberalism on Cognitive Flexibility and Working Memory Performance

Although models of political ideology traditionally focus on the motivations that separate conservatives and liberals, a growing body of research is directly exploring the cognitive factors that vary due to political ideology. Consistent with this emerging literature, the present research proposes that conservatives and liberals excel at tasks of distinct working memory processes (i.e., inhibition and updating, respectively). Consistent with this hypothesis, three studies demonstrate that conservatives are more likely to succeed at response inhibition and liberals are more likely to succeed at response updating. Moreover, this effect is rooted in different levels of cognitive flexibility and independent of respondents’ demographics, intelligence, religiosity, and motivation. Collectively, these findings offer an important perspective on the cognitive factors that delineate conservatism and liberalism, the role of cognitive flexibility in specific working memory processes, and the impact of political ideology on a multitude of behaviors linked to inhibition and updating (e.g., creativity, problem-solving, self-control).
Application of an intangible asset valuation model using panel data for listed enterprises in Vietnam

Intangible assets play an important role in increasing the value of companies. The performance of companies increasingly depends on ideas, information, and professional services rather than tangible assets. The question of how to accurately measure intangible assets remains a challenge for many scientists. This study aims to measure intangible assets of 396 companies listed on Vietnam’s stock market between 2010 and 2014 using the panel data technique by Yamayuchi (2014). The estimation shows that intangible assets make up a large share of total assets of companies. In addition, construction, steel, building materials, mining, and food are sectors with high intangible assets in Vietnam. The study also finds a positive impact of intangible assets on improving company performance. The findings demonstrate the importance of investing in intangible assets, such as R&amp;D, technology, advertising, and human resources, to increase the value of a company in the future.
Analysis of Corporate Governance Index using Asean Balanced Score Card and Firm Performance

Governance plays a crucial role in most activities of socio-economic life. For any organizations, units, businesses or higher, a country, a community, the role of governance becomes more important than ever. For businesses, with globalization taking place and market becoming more competitive than ever, good Corporate Governance is now considered as a factor of success. Good corporate governance will help the company improve its ability to access to various sources of capital and operate more efficiently. However, in Vietnam particularly, Corporate Governance system still need to enhance and improve. Therefore, with the aim of surveying the current situation of Corporate Governance practices in Vietnam and giving the analysis of its impacts on businesses’ performance, this research is conducted from a sample of 60 listed-companies in both Construction and Food & Beverage industry for the time 2015, 2017 and 2018. By using the tool of ASEAN balanced scorecard to evaluate Vietnam Corporate Governance practices on 05 aspects: Rights of shareholders, Equitable treatment of shareholders, Roles of stakeholders, Disclosure and transparency and Board duties and responsibilities, the paper came to the low results of companies’ Corporate Governance practices in Vietnam. Based on this method, different relationships were found, one of which is the positive relationship between Corporate Governance Index and Tobin’s Q. Keywords: Asean Score Card, Corporate Governance Index, Performance DOI: 10.7176/RJFA/11-6-02 Publication date: March 31 st 2020
Double skin façade assessment by fuzzy AHP and comparison with AHP

ABSTRACT A double-skin façade (DSF) has been widely used in recent years for its thermal and aesthetic properties. DSFs can also control wind pressure, manage natural ventilation and provide noise insulation. This study aims at providing an assessment of DSF to building designers and builders with their selection of façade systems. The decisions taken on the selection of façade systems are complicated ones based on multiple criteria. A decision must be taken only after many criteria are evaluated. While certain criteria such as heat insulation, noise insulation, and cost can be easily quantified, it is difficult to measure subjective criteria such as aesthetics. Therefore, the study aims at reflecting the experience of professionals who have applied such façade systems, to be able to evaluate all assessment criteria and façade systems. Architects or engineers working in the construction sector assessed criteria and DSF alternatives by replying to a questionnaire. Fuzzy set theory aids in measuring the ambiguity of concepts that are associated with human being’s subjective judgment. Fuzzy Analytic Hierarchy Process (FAHP) has been applied to many assessment problems. It is used for the assessment of DSF in this study. AHP was used for the assessment of DSF in our previous study. The results of our previous study are also compared with the results of this study and findings are presented.
Soviet Cold War Maps: Examining the Organization and Practices of Production Through the Case of Denmark

ABSTRACT During the Cold War, the Soviet military carried out an ambitious mapping programme, which resulted in a global series of topographic maps. Although recent advances in scholarship have increased our knowledge of the production of these maps, we still know little about the organization behind them. Based on information from a set of 466 1:50 000-scale Soviet military topographic maps of Denmark, this article examines the Soviet mapping practices related to the large-scale mapping of Denmark. Results show that the Soviet military compiled large-scale topographic maps of Denmark between the 1950s and the 1980s. The maps were initially based on Danish maps, but later the Soviets began to prefer remote-sensed data from satellite imagery. This allowed the Soviets to capture information about concealed military infrastructure. The article also shows the potential for using information from the map sheets in a transnational analysis of the Soviet mapping during the Cold War.
Response Cries Inviting an Alignment: Finnish huh huh

ABSTRACT This study looks at the use of the Finnish response cry huh huh as a device to invite an alignment and to assess joint physical experience. Response cries establish a speaker’s orientation to the world, but they also give cues for the recipient on how to respond to the responsive actions appropriately. While the meaning of huh huh is unproblematic for the recipients, both speakers and recipients orient to the vagueness of huh huh through their turn design and turn formulation. Of particular interest are those rare huh huh turns that are repeated by the receiver with prosodic upgrading or downgrading compared to the initial ones. Initiating a sequence with a response cry and repeating it in the second position prove to be effective devices for the participants to maintain social solidarity in physiologically or emotionally dense moments. The data are in Finnish with English translations.
