Chitosan‐based fiber‐sponge materials as a promising tool for microalgae harvesting from Lake Baikal

AbstractMass eutrophication of microalgae and cyanobacteria is observed in Lake Baikal in the past decade. In this paper, the concept of replaceable adsorption filter material based on chitosan flocculant filler and chlorinated polyvinyl chloride polymer nonwoven material are proposed. Functional and mechanical properties and morphology of the material are investigated depending on a packing density and a degree of chitosan filling. The introduction of 45% chitosan increases the Young's modulus up to 10 times, and it makes the material more rigid in 2.8 times. The high efficiency of sorption and growth inhibition of cumulative biomass culture was shown. The biomass source is taken from the coast of Barguzinsky Bay of Lake Baikal. Dominant species is microalgae of Scenedesmus genus.

Exploring the Trading Zones of Digital STS


 Over the last couple of decades, one of the significant developments in digital STS has been the rapid growth in digital methods and tools for data harvesting, analysis and visualisation. The increasing availability and deployment of digital tools raises questions about how to develop an analytic practice that reconciles the theoretical sensibilities of STS with tools and data that may sometimes be grounded in assumptions alien to STS. This article explores these challenges by reporting on two related digital STS projects that were carried out at the Techno- Anthropology Lab in Copenhagen. Drawing on science historian Peter Galison’s notion of trading zones, the article analyses how project participants from different communities of practice exchanged and combined tools, theories and projects in a variety of ways. The article identifies two particular trading strategies: the introduction of assisting ontologies or mini-theories, and the introduction of project-specific problems and success criteria. In the final discussion, the article argues that a reliance on these trading strategies in the future will require digital STS to maintain and cultivate its theoretical sensibilities through a continued dialogue with the broader field of STS, including, in particular, new interventionist forms of STS scholarship.

Background of this study is on how the right plantation management practices become the absolute provision to gain eminent yield. Thus the company must evaluates the application on the technical culture of mature plant in order to know how big is the value and influence of the technical culture application so that the company can attain the optimum production.Therefore this study aims to identify and calculate the application rate of cultivation technique factors that have been applied by the company itself also to calculate the loss rate from misapplication of cultivation techniques that have been affected oil palm production based on the cultivation technical manual and estimated loss value incurred by PPKS Medan and identify the efforts made by the company to control pests and diseases (HPT) also the development of oil palm pollinating insects (SPKS). The method used in this study was field observation method, and descriptive statistical analysis (tabulation). There were some indicators that used in field observation in this study, they are imperfect pollination in fruit development phase, oil extraction rendement (OER) and kernel extraction rendement (KER), harvesting technique and discipline on collecting loose fruits, harvesting unripe fruits, harvesting rotation >15 days, crop damage due to rat pests. The result showed that the technical culture application rate has different value in each indicator, based on the highest error rate the first was harvesting rotation > 15 days (52,75 %), second was imperfect pollination (7,05 %), third was harvesting technique and discipline on collecting loose fruits (7%), forth was crop damage due to rat pests (4,3%) and the last was harvesting unripe fruit (3,4%). The different value in application rate could be influenced by inadequate human resources, lack in controlling, facilities and infrastructure availability (like pollinating insect box, harvesting tools and good transportation access)

Empirical Research on Web Harvesting in the Process of Text and Data Mining in National Libraries of EU Member States

Almost two decades of experience on web harvesting and archiving are counted; the subject of web harvesting and web archiving have been top in the interest of researchers, technologists and librarians-information scientists. Web harvesting projects and pilot programs on archiving content traced on the Web are becoming priorities for national libraries and cultural heritage organizations in the EU. This paper pertains to web harvesting as a process for data mining from web and only through web (“pull” function); this paper elaborates upon research implemented in the framework of the funded research project titled “Web Archiving in Public Libraries and IP Law” that focused on the processes of web-harvesting and archiving as well as Text and Data Mining (TDM) operations in the national libraries of EU Member States. Web archiving as an official operation in national libraries of EU Member States creates web collections and preserves them for the purpose of being accessible and usable in perpetuity. This paper pertains to research on various components of web harvesting and archiving through an online survey (qualitative research) which targeted the national libraries of EU Member States. The research team of authors posed seventeen questions to EU national libraries. The survey output comes from answers delivered by 22 national libraries of EU Member States. The questionnaire was created through the use of Google forms. The researchers reached the EU national libraries via email and follow up telephone calls seeking libraries’ participation in the research. The aim of the research was to delve on participant libraries’ Text and Data Mining operation leveraging on Web harvesting and Web archiving technologies and operations. Results analysis reveals that web harvesting is considered among national libraries’ top priorities; the relevant projects increase in number, the web collections become more and more and the technological infrastructures and tools for web harvesting improve. Yet, there are many issues that remain unresolved. A significant number of surveyed libraries consider that legal and technical issues remain the most important to resolve. Access to harvested material is still under legal restrictions. The Directive 2019/790/EU on Copyright in the Digital Single Market (DSM) creates a favorable legal foundation for the deployment of web harvesting operations in national libraries of the EU Member States. TDM technologies make possible new areas of research. Web harvesting that was initially aimed for preservation purposes now expands to unprecedented research of national heritage through state-of-the-art automated TDM processes.

High‐performance antenna for energy harvesting in satellite health monitoring system

This study is targeted towards designing and analysing the X and Ku bands receiving antenna using the Code Blocks software and Advanced Design System simulation tool for energy harvesting in order to satisfy the energy needs of autonomous wireless sensors on board of geostationary satellite for structural health monitoring of the satellite panels, where weight, cost, size and efficiency are the principal space antenna parameters accounted. The energy harvester generally consists of receiving antenna, which harvests and scavenges the circumambient electromagnetic field and inputs the rectifier in order to power the sensors. In this study, a compact, wideband semi-ellipse patch antenna backed with defected ground structure is presented. The antenna compactness (186.8 mm3) is obtained by truncating the elliptical patch to form a semi-ellipse patch without compromising the band of interest which reduces from launching weight and cost. The proposed antenna covers X and Ku bands for voltage standing wave ratio ≤2 with a maximum return loss of 28.75 dB, the efficiency of 95%, the gain of 9.6 dBi and directivity of 14 dBi, which makes the proposed antenna compatible to use with the rectifier in order to satisfy the energy needs of wireless sensors.

Fluorescence coupled with chemometrics for simultaneous monitoring of cell concentration, cell viability and medium nitrate during production of carotenoid-rich Dunaliella salina

Two-dimensional (2D) fluorescence spectroscopy was investigated as a monitoring tool for cultivation, harvesting, and effluent treatment of Dunaliella salina with high carotenoid concentration; aiming to improve the production process and minimise costs. Chemometric analysis, namely Principal Component Analysis (PCA) and Projection to Latent Structures (PLS), were used to build models for estimation of cellular concentration, cellular viability, and nitrate concentration in media. The estimations were based on fluorescence excitation-emission matrices (EEMs) acquired directly from algal suspensions. Cell concentration during cultivation and harvesting can be predicted by a single model capturing 92.0% of the variance, and with R2 of 0.92 and 0.97, for training and validation, respectively. Cell viability during harvesting by ultrafiltration was modelled with 79% of variance and R2 of 0.79 for training and 0.73 for validation. Nitrate concentration was successfully predicted during cultivation and permeate treatment using a single model with 81.8% of variance and R2 of 0.82 for training and 0.80 for validation. Therefore, this work demonstrates the strong potential of combining 2D fluorescence and chemometrics for monitoring different processes during microalgae production.

Determining disaster severity through social media analysis: Testing the methodology with South East Queensland Flood tweets

Social media was underutilised in disaster management practices, as it was not seen as a real-time ground level information harvesting tool during a disaster. In recent years, with the increasing popularity and use of social media, people have started to express their views, experiences, images, and video evidences through different social media platforms. Consequently, harnessing such crowdsourced information has become an opportunity for authorities to obtain enhanced situation awareness data for efficient disaster management practices. Nonetheless, the current disaster-related Twitter analytics methods are not versatile enough to define disaster impacts levels as interpreted by the local communities. This paper contributes to the existing knowledge by applying and extending a well-established data analysis framework, and identifying highly impacted disaster areas as perceived by the local communities. For this, the study used real-time Twitter data posted during the 2010–2011 South East Queensland Floods. The findings reveal that: (a) Utilising Twitter is a promising approach to reflect citizen knowledge; (b) Tweets could be used to identify the fluctuations of disaster severity over time; (c) The spatial analysis of tweets validates the applicability of geo-located messages to demarcate highly impacted disaster zones.

Development of the Electromagnetic Regenerative Shock Absorber as an Energy Harvesting Tool for Vehicles

This research is a development of previous research entitled "Designing Regenerative Shock Absorber as a Vibration Energy Harvesting Tool on Vehicles" in the PUPT scheme funded by PNBP UNP 2017. In this study optimization of design oriented to energy generation was carried out while also paying attention to aspects driving comfort that might change due to the installation of a harvesting energy mechanism. One aspect of the change occurred in the type of magnet used, namely a ring type magnet with a type of neodymium material.From the test results obtained by changing the value of the efficiency of the shock absorber after the ERSA mechanism is installed by 2%, this condition also has an impact on the dissimilarity of the attenuation value obtained by 2% for the front-rear (left) and (right) wheels. In terms of generation voltage obtained the maximum generation voltage obtained is 25,600 mV. Based on the data obtained, it needs further development ERSA, especially in the aspect of the electromagnetic mechanism to optimize the generation of electrical energy.

Financial Analysisof Rain Water Harvesting Tools in Pamor Hamlet, Banjardowo Village, Kradenan Sub District, Grobogan District

The drought that occurs in the dry season is one of the hydrometeorological disasters. A total of 82 villages of 12 districts in Grobogan, Central Java, experience a clean water crisis due to drought because the well, as their main source of water, is likely to go dry. Therefore, a solution is needed to anticipate the water shortage. The aims of this paper is to analyze financially the water harvesting building which can be used as a reference for the community. The research was conducted in Pamor Hamlet, Banjardowo Village, Kradenan District, Grobogan Regency. The method used was to build the rainwater harvesting engineering models, namely (a) recycling tools for washing and bathing, (b) dirt filter wells, (c) three meters depth infiltration wells (1 well and 2 wells), and (d) five meters deep infiltration wells (1 well and 2 wells). Data collection was done by conducting a survey of the community. The data collected were the costs required for the construction of the rainwater harvesting equipment, maintenance, electricity, supporting materials, etc. The income was approached with replacement costs if the community buys water during the dry season. The financial analyses of NPV, IRR, BCR, and PP were employed. The results showed several feasible models to be applied, namely recycling equipment for washing and bathing, dirt filtering equipment, three meters deep infiltration wells (1 piece) and a depth of 5 meters (1 piece). This model is very good to be adopted by the community because it is easy and has minimal costs.

Analisis Antropometri Petani Dan Aplikasinya Pada Desain Alat Pemanen Manggis

Harvesting of mangosteen is manually by climbing trees or using simple harvesting tools that made from bamboo. In order to increase productivity, it is necessary to design mangosteen harvesting equipment by referring to harvesting anthropometry. Anthropometric data were collected from 30 (thirty) mangosteen harvesters which included height, shoulder height, knee height, arm length, hand reach up to grip, front hand reach, palm length, index finger and thumb diameter to the middle finger. The making of the tool refers to the 5th percentile data to get the maximum dimension of the tool for farmers who have SMAll and comfortable bodies for those who have large bodies. The results showed that the average harvesting height was 150 cm, shoulder height 125 cm, knee height 37.92 cm, arm length 47.62 cm, hand reach above grip 177.54 cm, forward hand reach 65.67 cm, the front hand reaches 59.45 cm, the thumb grip diameter to the index finger 37.70 mm, and the thumb grip diameter to the middle finger is 44.17 mm. Based on the anthropometric data, the design of the harvesting equipment was obtained using a telescopic system with a length of 3 m which can be shortened to 1.5 m, the diameter of the handle 3.2 cm, and the shape of the mangosteen fruit resembling the letter “V” with an aluminium plate construction.

Near-infrared image-guided laparoscopic omental flap for breast cancer.

Near-infrared (NIR) imaging with indocyanine green (ICG)-enhanced fluorescence is widely used in laparoscopic surgery. This study aimed to evaluate this technique's feasibility and usefulness in intraoperatively assessing vascular perfusion in a laparoscopically harvested omental flap. From March 2015 to February 2016, we prospectively evaluated patients undergoing breast cancer surgery followed by immediate breast reconstruction using a laparoscopically harvested omental flap. After laparoscopic preparation of the pedicled graft, the perfusion area of the omental graft was evaluated by using intraoperative Doppler ultrasonography and NIR imaging with intravenous ICG injection. Graft viability was evaluated by using Doppler ultrasonography 2 days postoperatively; for cosmetic outcome, Breast Cancer Conservative Treatment Cosmetic Results software was used 1 month postoperatively. The laparoscopic harvesting of an omental flap was successfully performed in eight patients without conversion to open surgery. The mean time to the initial detection of ICG-enhanced fluorescence uptake was 3.25 ± 1.16 minutes. On intraoperative Doppler ultrasonography, a pulseless area ≥10% was detected in five patients (62.5%). However, NIR imaging revealed no patients had an ischemic portion ≥10%. There were no ICG-related intraoperative or postoperative complications. All patients showed patent vessels on Doppler ultrasonography 2 days postoperatively. Cosmetic outcomes were mostly favorable 1 month postoperatively. The Breast Cancer Conservative Treatment Cosmetic Results evaluation 1 month postoperatively showed excellent, good, and fair results, with no poor scores. With regard to vascular perfusion, ICG-enhanced NIR imaging is a feasible and useful tool for harvesting a laparoscopic omental flap in breast cancer patients.

Measuring the social impact of nursing research: An insight into altmetrics.

The objectives of this study were to (a) identify nursing journal articles that provoked the most online activity and discussion and (b) assess the association between these articles' altmetric scores and publication characteristics, citation counts; and publishing journals metrics. Altmetrics, or alternative metrics, have recently emerged as a complementary way of measuring the societal impact of research by assessing the public engagement with research output. To date, no studies have yet investigated the online attention about scientific papers published in the nursing field. Integration of quantitative and qualitative synthesized evidence. InCites Journal Citation Report was used to identify a list of nursing journals indexed in the Web of Science Core Collection. Altmetric Explorer was selected as an altmetrics harvesting tool. The search in Altmetric Explorer yielded 66,608 research outputs from 118 nursing journals. The articles with the top 100 altmetric attention score (AAS) were identified and a new search, limited to only those 100 articles, was run to produce aggregate metrics specific to those articles. The articles were also exported for thematic analysis. The median AAS for the 100 articles was 248, ranging from 138 - 649. The articles were mostly discussed on Twitter, followed by news outlets and Mendeley. Articles indexed in the nursing journals category attracted low online attention compared with articles published in other health journal categories. Twitter remained the dominant source of attention over the years 2012-2018, followed distantly by news outlets. Most online attention came from the USA and the UK. Of the top 100 articles included in the study, the Journal of Advanced Nursing published the highest number of articles (N=26; Median AAS=179). The AAS was not significantly different between articles published in Q1 journals and those published in Q2 and Q3 journals. There was a significant relationship between articles' AASs and their citation counts on Scopus and Web of Science. Publication date was significantly related to citation counts on Scopus and Web of Science but not with AASs. Altmetrics will likely continue to evolve alongside the rapidly expanding use of social media and online platforms. As nursing continues to strive to have our research and scholarship inform policy, translated into practice and recognized for its scientific merit, we have to remain vigilant about the best ways to disseminate the important work we are doing. Research, such as this study, will allow nursing scholars to benchmark our progress as we adapt to the changing environment for measuring impact and quality in the digital age.
