Authors: Male Yusthinus T , Seumahu Cecillia Anna , Malle Dominggus
Published: February 2020

Bioremediation is a method that use microorganism to extract heavy metal from contaminated waste. In this research Aspergillus niger was used to extract heavy metal such as Pb and Cd of marine sediment from Waiheru shore, Inner part of Ambon Bay, which was detected as significantly high heavy metal contaminated site among seven sites. Bioremediation were done using Aspergillus nigers to extract Pb and Cd metal from sediment, then their solubility being measured in filtrate media. Result shows that Cd metal were only detected 15 days after incubation while Pb were detected since the first day incubation. This result also showing the fluctuating solubility of Pb metal. It is suspected that this occurs due to biosorption ability of the fungi that being used which triggers metal accumulation in the cell structure. It is therefore can be concluded that Aspergillus niger can be used in bioremediation of sediment that are being contaminated by Pb and Cd heavy metals.

Published: February 2020

This study aimed to measure production risk and income risk of cocoa farming in Kolaka Regency and to determine the factors that influenced the behaviour of farmers towards the risk. This study involved 142 cocoa farmers spread across the Kolaka Regency. The research method used to measure production and income risks used the coefficient of variation and to measure risk behaviour using the Ordardi Least Squares (OLS) method of the Moscardi and De Janvry models. The OLS method was used to analyse the factors that influence the behaviour of farmers towards the risk of cocoa farming. The results of the coefficient of production variance and income of cocoa farming were high, which were due to the attack of cocoa pods, the use of various fertilisers and pesticides, as well as fluctuating prices. This means that production in cocoa farming has a high chance of failure. Analysis of the average value of aversion to the risk of cocoa farming is 1.5643, assuming that (1.2 ≤ K (S) ≤ 2.0), meaning that on average cocoa farmers in the Regency are risk averters.  Factors that influenced the behaviour of farmers towards risk were the area of ​​arable land (ha), farmer education, farmer experience, number of cocoa plant stands, with significant effects; meanwhile, farmer age, dummy planting patterns of cocoa-coconut-nilam and cocoa-coconut-cashew had insignificant effects.

The effect of the polyaniline content on the mechanical, rheological and electrical properties of polyethylene and polyvinylchloride compositions for the production of antistatic and semiconductive materials was established. Samples of polymer composites were obtained in two stages: 1) mixing of components in a mixer type "disk in disk"; 2) pressing into films by the method of "hot pressing." Tensile strength, relative elongation, melt flow index and specific volume electrical resistance of the compositions were investigated by standard methods. It was found that an increase in the volume content of polyaniline in the polyethylene and polyvinylchloride matrix leads to a monotonic decrease in the melt flow index, as well as tensile strength and relative elongation. At the same time, there is a significant decrease in the specific volume electrical resistance in polyethylene and polyvinylchloride composite films, which contain up to 30% vol. of polyaniline. The reduction of the tensile strength and the relative elongation of films from compositions containing up to 30% vol. of polyaniline. This is due to the decrease in the viscosity of the melt-filled compositions, as evidenced by the decrease in the flow index of the melt polyethylene compositions from 3 to 2 g / 10 min, and polyvinylchloride – from 13 to 3 g / 10 min. Specific volume electrical resistance naturally decreases with increasing volume concentration of the filler in ranges from 1014 to 102 Ohm ∙ m for polyethylene compositions and from 1010 to 101 Ohm ∙ m for polyvinylchloride compositions. The developed polyethylene and polyvinylchloride compositions filled with polyaniline can be used for the production of polymer products with antistatic and semiconductive properties.

Textile manufacturing owned by the Jews in Galicia at the end of ХІХ – the first third of XX century is studied in the article. On the basis of archive documents and author’s field materials, preconditions for establishing relevant centers are determined; the main factors that influenced the textile industry development are highlighted. The attention is focused on knitted and lace goods manufacturing of both new and fancy assortment of the period under the study. The principle of a systematic approach and complex study constitutes the methodological basis. In order to investigate the selected object of study, historical and art studies methods are applied. During the scientific expeditions while collecting materials from the old inhabitants the interview method was used. Textile manufacturing in Galicia is divided into two main directions: according to the manufacturing principle: folk textile, where centuries-old traditions prevail, and professional textile, where specialists and special-purpose equipment are involved and fashionable trends are considered. It was found that at the end of ХІХ – the first third of XX century a considerable part of local textile industry was owned by the Jews. To some extent, this was due to the fact that they received proper education, set up own businesses, produced assortment that met the demands of consumers of various strata of society. Knitted and lace goods manufacturing, which became fashionable both in urban and rural areas, was productive. It was ascertained that apart from fancy goods, traditional woven Hutsul «zapaska», carpets and «kraikas» involving local population were manufactured. The scientific novelty consists in the study of one more aspect of textile industry in Galicia where the attention is focused on the peculiarities of manufacturing the textile assortment in the centers belonging to the Jews. The study allows expanding knowledge of textile industry in Galicia, clothes assortment and interior fabrics manufacturing centers, which favours involving the received data to learn the history of textile in Galicia.

To analyze Ukrainian ethnic elements in interior design. Based on the consideration of relevant samples, to reveal the origins and features of the elements that are used in the artistic and aesthetic organization of the hotel interiors designed in Ukrainian style. To determine the basic concepts in the article, there is a method of terminological and semantic analysis applied. Sources on the topic of research, normative scientific and methodological documentation are reviewed with the methods of comparative analysis. For historical sources the chronological method is used. Domestic and foreign implementations and operations of projects are examined with elements of a critical analysis. The systematization of materials is based on the methods of analysis and synthesis. This paper analyzes elements of Ukrainian artistic culture in hotel interior design. Ethnic elements in hotel design have been identified as having important functions – informative, informative, aesthetic, decorative, historical, cultural, educational and educational. In the conditions of military confrontation for many Ukrainians the ethno-national style of the interior, formed through the targeted selection of folk elements and motifs, also acquires a patriotic color. Such semantic expressiveness contributes to the active dissemination of design in ethno-national stylistics both in the field of housing interior and commercial premises. Thіs study identified the source of inspiration source of inspiration for creating interiors using ethnic elements and motifs is Ukrainian folk culture. Its diversity is presented in the works of folk architecture, fine and decorative art, amateur works of folk artists, as well as their stylization by professional artists. In the study, the author concludes that interior design in folk style using elements of the artistic and material culture of Ukraine is a kind of guarantee of the preservation of its ethnocultural identity as the basis of national identity in modern architecture and the architectural environment. Scientific novelty of the results obtained is to identify the specifics of the use of Ukrainian ethnic elements in the modern hotel interior, and, in general, the modern principles of the formation of ethnic style, the disclosure of its semantic and semantic meaning, justification of its feasibility and aesthetic appeal through the use of appropriate design stylistics. The results can be used in design practice, as well as to achieve consistency and efficiency in the organization of the hotel interior.

Published: February 2020

Background: Mass Drug Administration (MDA) Programs has been
conducting bi-annually at school level to eliminate Soil
Transmitted Helminthiasis (STH) from Bangladesh since 2008. Because of very low MDA coverage in Bangladesh, this study explored the perceptions of
stakeholders about MDA program implementation, knowledge of students
regarding helminthiasis
and MDA including its potential barriers.

Methods: 258 students of grade IV of three public
schools from Khulna district, Bangladesh were
randomly selected. This study follows mixed-method approach while Qualitative methods were used to evaluate the
perception, barriers
and
favourable environment based on IDIs
and
FGDs with key stakeholders and quantitative method used to assess the students’ response to School-Based Health Education (SBHE) intervention and knowledge of STH and MDA.

Results: In
result, positive
understanding and attitude towards MDA program are seen within community as
well as have basic knowledge on STH. Rumour
of drugs potential side effects and insufficiently trained manpower are found
as key barriers. After SBHE intervention among urban and rural students’
knowledge improved by 64.31% and 13.04% respectively including MDA coverage has
increased by 40.08% and 8.69% respectively as well.

Conclusions: SBHE
intervention improves knowledge, but to make that knowledge effective and sustainable,
teachers need to get proper trainings on regular basis. Improved knowledge of
the community can increase MDA coverage if we are able to remove the program
obstacle like rumours of side effect of the medicine and constraints of skilled
human resources.

Commitment and Communication: are we committed to what we mean, or what we say?
Authors: Bonalumi Francesca , Scott-Phillips Thom , Tacha Julius , Heintz Christophe
Published: February 2020

Communication often involves making a commitment of some sort, for instance to a future action. But what does communicators’ commitment amount to? Specifically, are communicators taken to be committed to what they actually say (what is explicit), or to what they mean (including what is implicit)? Some researchers claim that communicating implicit information leads to a lower attribution of commitment and less accountability than does communicating explicit information. Here we present two studies exploring whether the implicit-explicit distinction affects commitment attribution in promises (commissive speech acts), and, crucially, whether commitment attribution is further modulated by degree to which the hearer will actually rely on the promise. Our results support the conclusion that people perceive communicators to be committed to ‘what is meant’, and not simply to ‘what is said’. More generally, our findings add to the experimental literature showing that the implicit-explicit distinction is less pervasive than previously claimed, and that its role in commitment attribution might have been overestimated.

SARS-Cov2 enables anaerobic bacteria (Prevotella, et al) to colonize the lungs disrupting homeostasis, causing long-drawn chronic symptoms, and acute severe symptoms (ARDS, septic shock, clots, arterial stroke) which finds resonance, with key differences, in the ‘forgotten disease’ Lemierre Syndrome, enabled by Epstein Barr Virus
Authors: Chakraborty Sandeep
Published: February 2020

Metagenomic studies of Covid19 patient sequencing data from different countries (China, Brazil, Peru, Cambodia, USA) shows a pattern that SARS-Cov2 enables anaerobic bacteria (eg Prevotella, Veil- lonella, Capnocytophaga, Fusobacterium, Oribacterium and Bacteroides) colonize the lungs, disrupting the homeostasis found in healthy patients. Long drawn symptoms in Covid19 have caused great con- sternation, and could be explained by persistence of biofilms. Some of these bacteria are implicated in increasing IL-6, cause ground glass opacity in lungs and are associated with cardiac injury - all symp- toms associated with Covid19. Many studies also show several bacterial infection markers - like D-dimer, LDH, C-reactive protein and ferritin - being significantly high, while the viral immune response is at- tenuated (reported by three studies till date). This is also confirmed here in the lung sample from a 74 year old deceased patient, showing high levels of IFITM3, ferritin and S100 calcium binding protein. Anaerobic bacteria causing initial symptoms like persistent fever, chills, pain and later symptoms like ARDS, blood clots, arterial stroke and septic shock finds resonance in a ”forgotten disease” - Lemierre syndrome (LS). While, LS is enabled by Epstein Barr Virus - possibly by ‘a transient depression of T cell immunity’, two recent studies show that IFN-λ might promote bacterial superinfection in Covid19. Also, 16S rRNA bacterial genes and endotoxins (LPS) were discovered in 18/19 severely ill pneumonia patients in one study, suggesting dissemination of endotoxins, and not actual bacteria, might suffice to cause severity. Autopsies also show foci of acute bronchopneumonia. There are key differences with LS - for example origin of LS is the jugular vein while Covid19 starts in the lungs (and this difference should result in Covid19 to be easier to treat). Co-infection of EBV and SARS-Cov2 leads to greater symptoms (fever, higher CRP) in a study of 67 patients. SARS-2003 showed a lot of similar symptoms, which did not get enough media attention. There was a specific warning issued in 2004 for ‘an increased vigilance against stroke and other thrombotic complications among critically-ill SARS patients in future outbreaks’. Enhanced pathogen testing kits, which include RT-PCT for bacterial genes and endotoxin tests, could confirm this disruption in Covid19, and thus anaerobic-specific antibiotics could significantly help in therapy.
Particle-turbulence interaction of high Stokes number irregular shape particles in accelerating flow: a rocket-engine model
Authors: Kalenko Sabrina , Liberzon Alexander
Published: February 2020

Metal particles in solid propellants enhance rocket engines performance. An interaction of particles with a high Reynolds number turbulent gas flow accelerating to a nozzle, has not been characterized thoroughly. We study the particle-turbulence interactions in a two-dimensional model of a rocket engine. Two-phase particle image/tracking velocimetry provides the flow velocity simultaneously with the velocities of irregularly shaped inertial particles ($d_p \sim 350 \mu$m, Stokes $St \sim 70$, particle Reynolds number $Re_p \sim 300$). We reveal the local augmentation of turbulent fluctuations in the particle wakes (up to 5 particle diameters downstream the particle). Despite the low mass fraction, the large response time of the particles leads to an increase of turbulent kinetic energy (TKE) everywhere in the chamber. The increase of local particle mass fraction near the nozzle, due to the mass conservation and converging streamlines, compensates for the dampening effect of the strong mean flow acceleration and further augments TKE at the nozzle inlet. Furthermore, this is accompanied by unexpectedly isotropic fluctuations in the proximity of the nozzle. The phenomenon of the isotropic, strongly enhanced turbulence in the proximity of the engine nozzle achievable with the low mass fraction of high $St,Re_p$ particles, can be used to improve the design of solid propellant rocket engines.

Personality Types Revisited – a Literature-Informed and Data-Driven Approach to an Integration of Prototypical and Dimensional Constructs of Personality Description
Authors: Kerber André , Roth Marcus , Herzberg Philipp
Published: February 2020

A new algorithmic approach to personality prototyping based on Big Five traits was applied to a large representative and longitudinal German dataset (N = 22,820) including behavior, personality and health correlates. We applied three different clustering techniques, latent profile analysis, the k-means method and spectral clustering algorithms. The resulting cluster centers, i.e. the personality prototypes, were evaluated using a large number of internal and external validity criteria including health, locus of control, self-esteem, impulsivity, risk-taking and wellbeing. The best-fitting prototypical personality profiles were labeled according to their Euclidean distances to averaged personality type profiles identified in a review of previous studies on personality types. This procedure yielded a five-cluster solution: resilient, overcontroller, undercontroller, reserved and vulnerable-resilient. Reliability and construct validity could be confirmed. We discuss wether personality types could comprise a bridge between personality and clinical psychology as well as between developmental psychology and resilience research.
Explaining Support for Post-Secondary Educational Funding for Indigenous Students
Authors: Genge Olivia , Day Martin V.
Published: February 2020

A concerning post-secondary education gap exists between Indigenous and non-Indigenous individuals in Canada. One program designed to help address this issue, the Post-Secondary Student Support Program (PSSSP), provides eligible First Nations students with post-secondary education funding. Although such programs are beneficial, it is unclear how much Canadians support public funding of Indigenous education and whether psychological research can help explain why some may endorse or oppose it. Thus, using the PSSSP as an example, we examined five possible psychological predictors of public support: personal prejudice towards Indigenous Peoples, perceived social mobility, meritocratic beliefs, group zero-sum beliefs, and political conservatism. Based on previous research, we hypothesized that all would negatively relate to support for the PSSSP. In a sample of non-Indigenous Canadian adults, we found that only higher personal prejudice, group zero-sum beliefs, and political conservatism uniquely explained lower support for the program (or conversely, lower prejudice, group zero-sum beliefs, and political liberalism, were related to higher program support). Although correlational, this study provides insight into factors that may influence Canadians’ attitudes toward a program aimed at addressing a consequential societal inequality. We discuss the implications of these findings with regards to support for programs and policies targeted at marginalized groups.

Reward prediction error and declarative memory
Authors: Ergo Kate , De Loof Esther , Verguts Tom
Published: February 2020

Learning based on reward prediction error (RPE) was originally proposed in the context of non-declarative memory. We postulate that RPE may support declarative memory as well. Indeed, recent years have witnessed a number of independent empirical studies reporting effects of RPE on declarative memory. In this paper, we provide a brief overview of these studies, point out emerging patterns, and identify open issues such as the role of signed versus unsigned RPEs in declarative learning.

AbstractBased on a report by the Directorate General of Pollution and Environmental Damage Control of the Ministry of Environment and Forestry (KLHK), in 2015 nearly 68 percent or the majority of the quality of cistern water in 33 provinces in Indonesia was in a heavily polluted status. The main source of river pollutants is domestic or household waste. Human behavior is the biggest cause of environmental damage. The purpose of this study is to link knowledge with people's behavior in disposing household waste in the Sago River. This type of research is quantitative research with a cross-sectional approach. The independent variable in this study is people's knowledge in disposing household waste. The population in this study were all housewives who lived in the area around the Sago river, as many as 974 people. The samples in this study were 284 people and the sampling technique was Stratified Random Sampling. The instruments used were questionnaires and observation sheets. Primary data obtained through questionnaires and observations while secondary data from Sukaramai Kelurahan Pekanbaru data. Data analysis used chi square test with a = 0.05. The results showed that there was a relationship between knowledge and the behavior of disposing garbage with a value a<0,05. This research would be used for further research, namely to make the right program in handling garbage in the Sago River in Pekanbaru. Keyword: Knowledge, Behavior, Trash, River

This article attempts to reveal the prospects of yoga tourism in Nepal. Yoga is gaining popularity worldwide due to its inherent quality to transform a person from illness to wellness. This is the reason yoga tourism is studied in academia under the umbrella term of wellness tourism. There are potentialities how Nepal can be one of the best destinations for yoga tourism. Nepal is spiritually saturated country being the birthplace of Gautama Buddha and playground of Lord Shiva, the Yogishwara. At the same time, Nepal is a Himalayan country including the highest mountain, Mt. Everest. The cultural heritage is another attraction. The simplicity of people attracts tourists who aim to learn yoga practices while visiting places for refreshment. This article has dealt about how yoga tourism is spreading, what are its theoretical and philosophical background, prospects and potentialities and so on. The major methodology applied in this article is library research, case studies and visiting actual places where yoga tourists from all over the world gather. Yoga retreat survey has revealed actual scenario of yoga tourism. Historicity of yoga philosophy is uncovered using original Classical Sanskrit Cannons. A sample survey identified yoga retreat centers in Kathmandu, the facilities available and potential aspects of tourism and income generation. The finding section documented the actual problems and prospects faced by the hosts, i.e., travel agencies, owners of yoga retreat centers, hoteliers, and yoga masters. The research has reached in conclusion: if right policies and facilities are generated, Nepal will gain a new identity as best destination for yoga tourism in the world. There are potentialities to develop internal yoga tourism as well. One can visualize Nepal being famous and prosperous from yoga tourism and Nepalese people gaining health, wealth and wellbeing by living yogic lifestyle and collecting reputation as yoga masters by guiding tourists into yoga life.

International humanitarian law (IHL) applies at times of armed conflict, placing legal obligations on all warring parties that are designed to limit the inhumanity of warfare. Armed Police Force (APF), Nepal with the mandate to control an armed struggle occurred or likely to occur in any part of Nepal, to control armed rebellion or separatist activities or likely to occur in any part of Nepal, and to provide assistance in case of external intervention being under the Nepali Army, can at any time become a party in both international and non-international armed conflict. APF’s role in UN Peacekeeping Missions is also an area where it may have to engage with non-state actors if and when situation demands. All these necessitate APF personnel to have proper understanding and compliance to the principles of IHL, violation of which can increase human suffering and consequent individual criminal responsibility and command responsibility. In light of this, it concludes the IHL specific trainings in APF, Nepal should be maintained and augmented to ensure broad and better understanding and respect for IHL in times of conflict.

The number of children who overuse the device makes them less creative in writing and telling stories. In addition, children sometimes access news that is not suitable for them, such as scenes of violence, pornography, and porno-action. This condition also occurs in children in Ar-Rosyid Purwokerto. Community Service Program (PKM) in the form of journalistic training is conducted to build media literacy by developing children's creativity in the field of journalism, both in the form of writing and in the form of broadcasts.This training was held by lecturers and students of the Communication Studies Program at Universitas Amikom Purwokerto in mid September and October 2019 (every Saturdays). There were 20 elementary and junior high school students participated in this training. They joined the non-formal activities in Ar-Rosyid Purwokerto. The facilitators assisted the participants and provided them with knowledge and skills related to the journalistic principles and elements. The participants gained knowledge and skills on how to conduct interviews and observation, and write news according to journalistic rules. In addition, the participants gained experience about the radio broadcasting process and making journalism photos.

The effect of quenching and tempering temperature on the tensile properties and the yield strength ratio of 30MnB5, 27MnCrB5, and 34MnB5 boron steel have been investigated. Quenching (Q) and tempering (T) temperatures varied in the range of 850 to 950 °C and 150 to 450 °C, respectively. The mechanical properties of quenched and tempered steel were examined with the application of the tensile test and hardness testing. The microstructure was characterized using optical microscopy and X-ray diffraction. The increase in Q & T temperatures resulted in a decrease in the ultimate tensile strength (UTS), yield strength (YS) and break strength (BS) values and an increase in the yield strength ratio. The tempering temperature was found to be more effective on the UTS, YS and BS values than was the austenitizing temperature. It was noted that the effect of tempering temperature is greater on the ultimate tensile than on the yield strength for the investigated low alloyed boron steel. The effect of the tempering temperature on the elongation to fracture is also greater than the effect on the uniform elongation. The yield strength ratio showed a tendency to increase with increasing tempering temperatures. It was raised considerably by increasing the tempering temperatures from 300 to 450 °C, while it remained at a similar level between 150 and 300 °C. The ratio of ultimate tensile strength and mean hardness decreased with increasing tempering temperatures for the tested varieties of steel. Increasing tempering temperature leads to an increase in yield strength ratio and a total elongation and a decrease in the strength of the tempered martensite.
