Effect of laser power on conductivity and morphology of silver nanoparticle thin films prepared by a laser assisted electrospray deposition method
Authors: Pathak Pawan , Castillo-Orozco Eduardo , Kumar Ranganathan , Kar Aravinda , Cho Hyoung J.
Published: January 2021

Silver nanoparticle-based electrodes were studied extensively in recent years as an electrode material for wearable and flexible electronics due to their stability and conductivity. A wet chemical deposition technique is considered as a low-cost scalable technique. The current wet chemical-based nanoparticle deposition techniques include electrospray deposition, drop casting, spin coating, and the inkjet printing process. These techniques generally require a separate postdeposition annealing step. This can be a problem for substrates with a low melting point. In addition, some of the above-mentioned methods require physical contact, which increases the probability of cross-contamination. In this research, we present a technique that combines electrospray and laser radiation to deposit and sinter nanoparticles simultaneously on a rigid or flexible substrate. In this process, the microdroplets of aqueous silver nanoparticle suspension ejected in what is known as the microdripping mode from a metallic capillary nozzle, which can be controlled by an electric potential. A conical hollow laser beam is used to vaporize the liquid and sinter the nanoparticles at desired locations on a substrate. This is a promising technique compared to the traditional methods to fabricate conductive micropatterns due to its simplified one step deposition, suppressed cross-contamination, and applicability to various surfaces. Thin-film micropatterns of silver nanoparticles were fabricated using a Nd:YAG laser with powers from 5 to 13 W. The correlation between the grain size distribution, composition, and electrical resistivity was studied using a scanning electron microscope, energy-dispersive x ray, and four-point probe analysis. The results are comparable to the conventional thermal sintering method.

Published: January 2021

The term Diaspora has multiple layers of meaning in academic circles today. The term primarily used to refer to Jewish dispersion, came to be used to refer to contemporary situations that involve the experiences of migration, expatriate workers, refugees, exiles, immigrants and ethnic communities. The Indian Diaspora can probably be traced to ancient times when Buddhist monks travelled to remote corners of Asia. During the ancient times a large number of Indians migrated to Far East and South East Asia to spread Buddhism. The issues of colonialism and slavery, insider- outsider have posed the most difficult problems in the production of identity particularly for the black and third world people. In this way, the many diasporic–literary energies work today. For example, India, Africa, Canada and the West Indies have distinct diasporic backgrounds through which the respective writers’ works echo a variety of issues.

Published: January 2021

This writing deals with developing moral values by the ‘project citizen’ through several stages of its learning. Hopefully this article could act its role in enlightening and motivating for the teachers to be able to use this model later. Starting from the idea of character building by John Dewey (1859-1952) through the flow of Progressivism. He explains that "schools should make students as citizens to be more democratic, free thinking and intelligent". It can be interpreted that the role of the school as an institution must provide learning that can develop a wide range of student competence. The most appropriate learning strategies to achieve what is thought of this school is by using learning model of ‘project citizen’. This model is basically based on the strategy of inquiry learning, discovery learning, problem solving, and research-oriented learning. From the experiments which conducted, using the model is able to achieve competency in the subject of Civic Education. The model of project citizen learning has become the best model, which is able to develop the character of students through the process of participative learning. Therefore, educating character as a pillar of our national education goals, could be developed through the learning model of project citizen.

The work deals with Iranian women in the Czech Republic, aiming to find out how the position and social status of these researched women in Czech society are to a large extent shaped and influenced by the culture of the country of their origin. The article follows the reasons why these women left Iran, as well as relatives and family pressure on women. Furthermore, it is the society and ubiquitous social control that has influenced a number of decisions in women's lives, including marriage to a foreigner and emigration. The text deals with the historical and cultural consequences that gave rise to patriarchy and the emergence of feminist movements and thoughts in the Islamic Republic of Iran, and also discusses the perception of gender issues and the general position of women in Iran from the perspective of Western authors. Based on semi-structured interviews, the text shows the lived experiences of the studied women who left their home country to escape the local controlling environment. These women literally get themselves into a different foreign culture carrying their own cultural burdens with them. For Czech society, Iranian women are practically invisible, but they struggle with the daily dilemma of keeping cultural attributes and ties of their homeland or liberating themselves completely. In addition to several topics related to the context of cultural transmission, the article discusses patriarchy and family, feminism and the public sphere, including the symbol of the veil, and education, which includes the defining potential for changing a woman's lifestyle. The text (as well as the final thesis) can help with thinking about the issue of integration.

Special Stopping Space(RHK) is one of the facilities for motorcycles to stop at intersections during the red phase. RHK functions to separate motorbikes from other vehicles and is expected to reduce the obstacles that come from motorbikes. This Special Stop Room has been tested on a limited scale to support motorbike movement at signaled intersections in major cities in Indonesia. So far RHK at the Jambo Tape intersection has not been optimally functioning because there are still many motorcycle that cannot enter RHK. Therefore, this study aims to determine the level of service on Jambo Tape Intersection. The research was carried out using the simulation method using VISSIM software. The advantage of VISSIM is that it can model simulations in the form of video and get the value of the queue length and the value of time delay just by inputting the data of vehicles passing through the intersection. Traffic volume data is taken on Monday and Wednesday with direct observations in the field. RHK is considered unable to function optimally because there are still many motorbikes that cannot enter RHK. The closure of access (RHK) by four-wheeled vehicles is one of the reasons. Therefore, this study aims to plan the dimensions of motorcycle lanes in Special Stop Space (RHK), and analyze the effect of the level of crossing services using VISSIM software simulation . The advantage of VISSIM is that it can model simulations in the form of video and get the value of the queue length and the value of time delay just by inputting the data of vehicles passing through the intersection. In this study, a survey was conducted to obtain traffic volume, local and geometric velocity. The highest length of the Queue is at arm C, which is on T. Hasan Dek road at 163.36 m. The highest vehicle average delay is 132.119 seconds, the service level category F is greater than 80 seconds. By applying a special route to RHK, the highest volume occurred on Jalan T. Nyak Arief with the existing volume on the T. Nyak Arief road arm at 437 to 520 two-wheeled vehicles / Hour on RHK conditions using motorcycle lanes.
Воображая раскрепощение мусульманок советского Туркестана
Authors: Melentyev Daniil
Published: January 2021

The agitation posters on Muslim women's emancipation and Bolsheviks' gender policy open up a different perspective on the soft sociocultural reforms in Soviet Turkestan. Visual agitation was a means of cultural transfer of Europeanized and secular norms into the patriarchal public and private space and a tool for recoding the indigenous peoples' worldview. The paper investigates visual agitation and analyzes the principles of functioning of emancipation posters of Muslim women in a culturally sophisticated society. Agitation posters are examined as instruments of modernizing women's living environment in cities, villages as well as in the steppe (of a nomadic lifestyle). The paper partly raises the question of the potential limits of the perception of indigenous women's image. The theoretical researches of Soviet art critics are used for this analysis. There is an attempt made to analyze the visual propaganda in the cultural and psychological contexts as well as in terms of the artistic features of the images. The visual agitation is studied as an essential component of emancipation, which played a significant role in promoting the values of Soviet feminists in the first half of the 1920s.

LA NEGACIÓN DE LA HISTORIOGRAFÍA EN “PIERRE MENARD, AUTOR DEL QUIJOTE” Y RESPIRACIÓN ARTIFICIAL
Authors: Davis González Ana
Published: January 2021

This paper puts in dialogue the texts “Pierre Menard, autor del Quijote” (1939) by Jorge Luis Borges and Respiración artificial (1980) by Ricardo Piglia, because of the inclusion of the tale in the novel. Its analysis as a whole reveals a common denominator between the two texts: the epistemological deconstruction of historiography. Examining the texts from such an axis allows, on the one hand, to deepen the role played by the Borgian story in Piglia’s novel. On the other, it opens new channels to read “Pierre Menard” from a perspective linked to historiographical criticism, never mentioned before.
Plant Breeding Through Protoplast Fusion
Authors: Armita Devi
Published: January 2021

Protoplast culture (protoplast fusion) is one method of tissue culture that is widely used in plant breeding programs in a relatively short time. This method is used to overcome the problem of plants that are difficult or impossible to cross conventionally as well as used for species improvement by transferring the desired gene from the donor plant to the target plant via protoplast fusion. Protoplast fusion makes it possible to produce plants that are resistant to a disease and various abiotic stresses, rapid growth rates and have a better quantity and quality of metabolites than their parents. Various factors affect the success of fusion and regeneration of protoplasts into whole plants, including the source of explants, the composition of the enzyme solution and the duration of incubation, fusagen type and culture media for regeneration.

AbstrakManusia sebagai komponen sistem atau sub-sistem meskipun mampu beradaptasi dengan baik terhadap sistem operasional penerbangan, namun manusia cenderung labil dan juga paling sensitif terhadap pengaruh yang dapat berdampak pada kondisi dirinya. Kondisi waktu kerja yang berbeda-beda juga diperkirakan dapat mempengaruhi kondisi seorang pilot. Tujuan penelitian ini adalah untuk mengetahui beban kerja mental pilot ditinjau dari perbedaan jenis kelamin (gender) jika dihadapkan pada kondisi waktu (phases of time) operasional penerbangan yang berbeda-beda. Penelitian menggunakan metode Subjective Workload Assessment Technique (SWAT), metode ini menggunakan tiga kombinasi dari tiga dimensi dengan tingkatannya. Dimensi tersebut adalah beban waktu (time), beban usaha mental (effort), dan beban tekanan psikologis (stress). Dari hasil penelitian menunjukkan kondisi beban kerja mental yang dialami pilot berdasarkan waktu terbang adalah baik untuk pilot pria dan wanita diketahui bahwa kondisi beban mental pilot tertinggi pada saat penerbangan dilakukan pada dini hari (00.00 –05.59), pada saat libur, dan saat peak season.Kata kunci: Kecelakaan Pesawat, Jenis Kelamin Pilot, SWAT.AbstractPhases of Time Effect to the Pilot Mental Workload In terms of Differences Pilot Gender: Humans as a component of the system or sub-system although be able well adapted to the flight operational, but humans tend to be unstable and also most sensitive to the effects that can impact on his condition. Different working time conditions are also expected to affect a pilot's condition. The purpose of this study is to determine the mental workload of pilot in terms of differnces pilot gender if faced with different phases of time conditions. Mental workload measurements performed using the Subjective Workload Assessment Technique method (SWAT), this method using combine of three dimensions with their levels. The dimensions are time load, mental effort load, and psychological stress load. The result of studies shows that the condition of mental workload experienced by pilots refers to phases of time is in general (on average) in the high category (overload). While the overall showed that more pilots emphasize time factor in considering the factors of mental workload. The most burdensome conditions of a flight for man and woman pilot is when the pilot was conducted in the early morning, on weekends and during peak seasonsKeyword:Aircraft Accident, Pilot Gender, SWAT.

Educated unemployment in Indonesia has been alarming. To overcome the need to review psychologically besides physical steps taken. This study aims to describe and test psychological characteristics (achievement motivation and fear of failure) that affect university students' entrepreneurial intentions. This object research is 233 students at one of Pekanbaru universities, who were selected using a stratified random sampling technique. The analysis used in this study is confirmatory factor analysis from MPlus from Harrington (2009) and Chi-Square analysis to test the significance of the estimated variables. The measuring instrument consists of 3 scales, namely the scale of entrepreneurial intentions, the scale of achievement motivation, and the scale of fear of failure. The analysis results show that there is an influence of achievement motivation and fear of failure on entrepreneurial intentions among university students. This research implies that academics always hold seminars and training related to psychoeducation in overcoming negative affective problems to reduce the fear of failure among students to become entrepreneurs.

Considerable efforts have been made to characterize the meaningful conformers that a molecule can adopt, which is of great significance for understanding the structure-property correlation in the fileds of molecular biology, drug discovery, catalysis, materials science, etc. It is however challenging to differentiate and make use of the flexible conformers in solution, as they often experience rapid interconversion due to low isomerization barrier. We herein present a novel yet simple size-matching strategy for conformation identification. As a proof of concept, we rationally designed a three-dimensional model compound, namely hexaformyl molecule 1 exhibiting two types of conformers, i.e. Conformer-1 and -2 with different cleft positions and sizes. Aided by DFT calculations, we selected two triamino conformation capturers (denoted CC). Small-sized CC-1 selectively captured Conformer-1 by matching its cleft size, while large-sized CC-2 was able to match and capture both conformers. It therefore allowed facile differentiation of the two conformations by conventional NMR and X-ray analyses. These two erstwhile inverconverting and indistinguishable conformational isomers were made use of, leading to the discovery of two novel configurational isomers, namely two novel cage-like compounds with twin cavities, one exhibiting a sandglass-shaped and another with a dumbbell form, which we coined diphane.
