Who Creates Value?
Authors: Kostakis Vasilis , Pazaitis Alexandros
Published: December 2020

The Last Dance is a sports documentary miniseries focusing on the 1997-98 NBA champions Chicago Bulls and their star Michael Jordan. Through the lenses of The Last Dance, whose global popularity has been unprecedented for a documentary, we discuss value from a historical, political and cultural perspective. First, this paper provides a concise account of the ambivalent nature of value from a historical perspective. We then discuss the Bulls’ General Manager dispute with Jordan over whether the players or the organization win championships; and the Scottie Pippen “injustice” according to which Pippen, a top Bulls player, was underpaid. By addressing these two issues, we show that all value is collectively produced. We argue that all value approaches are imperfect, temporary and context-specific. We thus highlight the need for scholars and policymakers to critically discuss value and point to the commons sphere for more inclusive understandings of value.

Authors: Dharma Arie Satia
Published: December 2020

Following the increase in of the information available on the Web, it is important to diversity of its users and the complexity of Web applications. One web application that has a diversity of users is a news website. Customizing a website with the characteristics of each user is called personalization. The purpose of this study is to study the methods used in giving news recommendations using user personalization. Collaborative filtering method (CF) is one method that groups users based on the nature of the user. This CF method can be applied using the k-nearest neighbor (KNN) algorithm. The proximity between users in this algorithm is sought using the Pearson correlation technique and cosine correlation. The best technique by considering the smallest value of prediction error evaluation will be applied to giving recommendations. Evaluation of these errors was tested by applying the formula Root Mean Square Error. The best evaluation results obtained in this study are the k-nearest neighbor algorithm with cosine correlation similiarity.

Published: December 2020

In the last few decades, there have been advances in the field of innovative technologies used for the rehabilitation of people with a motor disability. A great example is the Brain-Machine Interface (BMI) technologies, which allow the control of machines through the brain activity of individuals and contributes to a reorganization of their motor and sensory systems. Thus, several evidences have suggested the use of technologies in the rehabilitation of these patients. The aim of this study was to perform a literature review on the use of technologies applied to motor rehabilitation. To carry out this study, a search for scientific articles was performed in the Pubmed, Scielo and Lilacs databases, in addition to the dissertations and theses found on the CAPES database. There were a total of 24 references, published between 2002 and 2020. According to the literature studied, there is an increase in resources that use technologies as therapeutic options. Many of the conventional interventions are being replaced or associated with these innovative technologies. With the advent of BMI technology and its use in human beings, a technological revolution can be observed in several biomedical areas, thus allowing a multidisciplinary application in the rehabilitation of motor, sensory or cognitive functions in patients. Despite the advances, this subject still shows controversies and before a broad recommendation, more randomized studies and a greater ethical recommendation on the subject will be needed.

The effects of smoking processes on the sensory and proximate components of two species of shrimp were evaluated. Sixty specimens of each species were distributed in a completely randomized design, with two treatments (T1 = hot smoking and T2 = liquid smoking), and fresh shrimps samples were used as control (T3). The sensory characteristics were evaluated using the 9 point hedonic scale and the acceptance index. The centesimal composition was evaluated based on 100 g from each treatment and the fresh samples. The data were submitted to one-way ANOVA and Tukey's test. The results of sensory analysis showed significant variations (p <0.05) for the attributes analyzed among the species, whereas among the smoking processes there was no significance (p >0,05). The acceptance rate was above 70% for amazonian prawn and 80% for white shrimp, regardless of the smoking method. The proximate analysis showed significant differences between the two smoking processes, hot and liquid, with moderet values of lipids, between 0.27% and 1.51%, and high protein values, of 24.61% 24.13%, for white shrimp and amazonian prawn, respectively. The smoking processes altered the sensory and chemical profile of the prawns, causing good acceptance and adequate nutritional constitution for smoked fish.

Mulheres, historiografia e história oral: um diálogo possível
Authors: Duarte Jessyca Barbosa , Freire Juliana Alice Costa , Jucá Gisafran Nazareno Mota
Published: December 2020

Este trabalho traz algumas considerações sobre a história das mulheres e as mudanças que aconteceram no campo historiográfico, assim como sua relação com a história oral, que nos possibilita compreender que através da oralidade o sujeito se encontra e reencontra com o contexto histórico e social. Pensar sobre a história das mulheres nos leva ao encontro de uma história em que, por séculos, a mulher foi vista de forma subalterna, sendo excluída dos processos educativos e sociais, silenciadas ao ponto de se duvidar se de fato elas fizeram parte da construção da história da humanidade. Diante do exposto, utilizaremos uma pesquisa de cunho bibliográfico, buscando fundamentos teóricos que nos auxiliem a compreender o surgimento de uma concepção que passa a considerar as mulheres como sujeitos ativos na história. Os resultados evidenciam as contribuições historiográficas na reconstrução na história das mulheres, o momento em que passamos a considerar outras perspectivas que não visem apenas à história de grandes personalidades masculinas do passado. A história oral traz como características o seu aspecto democrático, e possibilita que as mulheres encontrem mais um caminho capaz de fazer ecoar a sua voz, por séculos silenciada.

The agricultural industry is the main emitter of methane (CH4) and nitrous oxide (N2O), gases that each have a global warming potential that is greater than that of CO2 by 23 and 298 times, respectively. On a global scale, enteric fermentation from ruminant animal production (especially of cattle and sheep) is responsible for between 21% and 25% of total anthropogenic CH4 emissions. The search for effective, simple, and fast methods to measure the production of CH4 and other products from ruminal fermentation has been the objective of several studies on ruminant nutrition. Thus, techniques have been developed under experimental conditions of Brazil and other international countries to quantify CH4 emissions of ruminants. The objective of this literature review is to discuss and compare the existing techniques of measuring enteric CH4 from ruminants. Each technique has a shortcoming or disadvantage in its characterization of ruminal fermentation. The ex-situ technique of measuring CH4 from ruminal fermentation has been quite promising, because it facilitates the measurement of CH4 and other fermentation products, such as short chain fatty acids (SOFA). CH4 detection by a portable laser is effective in monitoring fluctuations in emission and is recommended especially for short-term measurements of respiring and eructating animals reared in a feedlot system. Other methods are being improved and better adapted for practical use in the ongoing quest for more efficient uses of ruminal fermentation products.

Published: December 2020

Salted food bars are an alternative in order to reach sugar reduction consumption. The challenge to create this type of bar is to substitute sweet binding agents. This study intended to evaluate the technological and nutritional aspects of salted food bars elaborated with different concentrations of binding agents (modified starch, hydrolyzed collagen and acacia gum) with low caloric value. The basic ingredients (oats, linseed, soybean, sesame, quinoa, dehydrated tomato, seasonings such as garlic, onion and dehydrated parsley and NaCl) were added to the binding agent solutions. The food bars were analyzed chemically, physically and physicochemically. The results demonstrated that the three binding agents tested presented technical viability of agglutination of the ingredients. The food bars presented high content of dietary fiber, low caloric value, and high mineral (Fe, Zn, Mn and Mg) contents. Cereal bars produced with acacia gum presented higher texture values related to the chewability parameter, which had a positive influence.

Authors: Martasari Rial Dwi , Lactuca Fama Agri
Published: December 2020

Well Completion Test is a testing activity undertaken to determine the depth of production zone and feed center depth as well as to calculate the estimated production capacity of a well. Well completion tests are performed on wells that have just been drilled by exploring the depth of the well, measuring pressure and temperature, water loss test and gross permeability test. As a result of exploring the RL well, the tool was placed at a depth of 2000 meters. Injectivity is done at different pump rates, pressure and liquid faces. The gross permeability test results obtained an injection of 202.22 lpm/ksc, an average specific capacity of 5.028 lpm/meter, transmissivity of 0.1208955 darcymeter and skin factor 3.33381. Next calculate the production estimation using the injection that has been converted and plot to the graph then obtained the result of the estimated potential production of a well that is 6,3 MW. After a well has completed a well completion test, the next step is to test the production for more accurate results, because of the well completion test itself the accuracy is only about 50% only, therefore the production test needs to be done for the results which in getting more accurate.

Hypervelocity stars: theory and observations
Authors: Tutukov A V , Dryomova G N , Dryomov V V
Published: December 2020

Relativistic velocity is a kinematic feature of micro-objects (elementary particles). Their application to macro objects (stars, planets, asteroids, neutron stars, and stellar-mass black holes) is currently under scientific discussion. This potential was recognized after Warren Brown discovered hypervelocity stars (HVSs) at the beginning of the 21st century. Jack Hills predicted these stars in 1988 due to the dynamical capture of a binary star by the central supermassive black hole (SMBH). The acceleration mechanism due to momentum exchange in the classical three-body problem provides the kinetic resource for HVS formation by the gravitational capture of the remaining component. The present threshold of the anomalous stellar kinematics exceeds ∼1700 km s−1 and can be reproduced by some mechanisms as alternatives to Hills’s scenario. HVSs can arise due to the collisional evolution of stellar clusters, supernova explosions in close binary stars, the orbital instability of triple stars, stellar captures from other galaxies, etc. Scenarios with the participation of black holes with masses ranging from stellar values to several billion solar masses are the most promising for the generation of anomalously high stellar velocities. Hills’s scenario has a special place in HVS studies, because, being based on the accidental capture of a binary star by the SMBH, it does not relate to the problem of the Galactic Center population. This scenario predicts self-consistent statistics of HVSs and captured stars which may be identified with S-stars. The discovery of S-stars played an essential role in studies of the Galactic Center; their dynamics have independently provided incontestable proof of the SMBH’s existence. This review briefly discusses the history of the discovery and investigation of HVSs and S-stars, provides an account of their observational statistics, and describes their modeling methods in the classical three-body and N body problems. We study the limits of the effective acceleration of stars in the classical Hills scenario and the modified mechanism that allows a change of one of the binary components to another SMBH. The acceleration acquired by the star in a mutual field of two SMBHs can produce stars with relativistic velocities (1/2 c−2/3 c). Using a self-consistent probabilistic model combining the classical and modified Hills scenarios, we predict the formation probability of HVSs in the Galaxy and of extragalactic stars with relativistic velocities. We discuss the prospects of searches for stars and asteroids with relativistic velocities by future space missions and using new knowledge about the Universe.
A Survey of Motivation in EFL Classes from the Perspective of Learners and Teachers
Authors: AlQuyadi Ahmed , Alwass Bakil
Published: December 2020

Incentives, drives and motivation are the main terms in psychology that strengthen the persistence towards the desired achievement. This paper investigates teachers and students’ perception of how motivation can be promoted and consolidated in the EFL classroom. More precisely, how teachers can raise the level of motivation inside and outside the language classroom. The significance of this study lies in the fact that once learners are motivated, they can easily realise that they are achieving a purpose of their language learning and that they are more willing to accept the challenge of some demanding tasks. In this study two questionnaires were used: one for 46 teachers (in English) and one for 75 students (in Arabic). Teachers were in favour of almost every item related to motivation, and their average scores were higher of than that of the students. Probably experience and knowledge of the issue played a major factor. In general, the questionnaires for both groups yielded higher results than the calculated average for every group; for teachers, it was 72%, and it was 60% for the students. In conclusion, encouragement, appraisal, and motivation are important in classroom activities to raise language learning awareness and learning persistence.
The Impact of Incorporating Stylistic Models of Inversion in Teaching Grammar on Students’ Comprehension of Literary Text
Authors: Jaashan Hasan Mohammed
Published: December 2020

Pedagogical stylistics increases EFL learners’ awareness about the way the language functions in different texts. It also enhances innovative learning and teaching. This study aims at knowing the impact of incorporating stylistic models of inversion in teaching grammar on students’ comprehension of literary texts. It also aims to explore the learners’ perceptions about incorporating them in grammar courses. The models were adopted by (Galperin, 1977). A total of 85 EFL learners at King Khalid University participated in this study; 41 are students of Grammar III and are divided into two groups (15, 26); 44 are students of Grammar IV and are divided into two groups (20, 24). The second phase of the research is a unified long text exam that contains stylistic models of inversion in literary texts and is given to all students. Generally, the post-test results show that the participants identify stylistic models of inversion that help them understand the meaning of texts. Moreover, the quantitative approach shows the learners' preference for incorporating models in grammar courses because they are important in comprehending literary texts.

Udara buang proses pirolisis masih menyimpan energi panas yang cukup tinggi dengan temperatur mencapai 800°C sehingga dapat dimanfaatkan sebagai media untuk merubah fase Refrigerant R-134a dari fase cair menjadi gas. Refrigerant R-134a yang sudah berubah menjadi gas digunakan untuk memutar turbin sebagai penggerak generator sehingga dapat menghasilkan aliran listrik dalam siklus Organic Rankine Cycle  (ORC). Refrigrant R-134a tidak menyerap panas dari proses pirolisis secara langsung. Panas dari pirolisis diserap melalui siklus thermal oil kemudian digunakan untuk mengubah fasa R-134a pada Heat Recovery Steam Generator (HRSG). Desain HRSG pada penelitian ini adalah tipe sistem Heat Exchanger shell  and tube. Dimana thermal oil yang memiliki suhu panas mengalir dalam shell dan refrigerant R-134a yang memiliki suhu dingin mengalir dalam Tube. Pertukaran panas terjadi ketika Refrigerant R-134a masuk ke dalam tube dan thermal oil masuk ke dalam shell. Dalam perancangan HRSG ini digunakan tiga variasi tekanan yaitu 8 bars, 10 bar, dan 12 bar. Data suhu, tekanan, diameter tube, dan mass flow rate di-input pada software HTRI Xchanger suite kemudian diproses oleh software tersebut sehingga menghasilkan output berupa laju perpindahan panas. Nilai laju perpindahan panas berturut turut sebesar turut 2,084 kJ/s, 2,622 kJ/s, dan 3,02kJ/s. Sehingga dapat disimpulkan hasil yang paling optimal berada pada tekanan 12 bar dengan nilai laju perpindahan panas sebesar 3,02 kJ/s Kata kunci: shell and tube HRSG, HTRI Xchanger suite, Organic Rankine Cycle

Potentials  of Rice Waste as Alternative Energy Sources in Southeast Sulawesi Province. The purpose of this study is to analyze the energy potential of rice processing waste (rice straw and rice husk) in the province of Southeast Sulawesi. Grain production data used the results of the Central Statistics Agency of Southeast Sulawesi publication as well as the Central Statistics Agency of the Regency / municipality of Southeast Sulawesi. To determine the pattern of utilization of rice processing waste at the farm level, the research team conducted a survey in several locations that produce rice in Southeast Sulawesi Province. The data used for analysis were grain production in 2010 – 2018. Based on the grain production, rice straw and rice husk production were calculated, then the energy potential of the two rice processing wastes can be determined. The results of the analysis show that the average production of rice straw was 823, 665 tons; rice husk was 119,289 tons, estimated energy potential of rice straw = 9,600GJ / year and rice husk = 1,700 GJ /year

Pisau merupakan suatu komponen pemesinan yang digunakan untuk memotong  benda menjadi potongan dan bagian. Begitu juga dengan pisau mesin pencacah plastik yang diharapkan bisa memotong plastik menjadi ukuran yang lebih kecil, dengan hasil potongan yang lebih kecil dapat memudahkan pada proses selanjutnya dan diolah menjadi produk jadi lainnya. Proses pencacahan plastik diharuskan mesin untuk bekerja terus menerus agar didapat ukuran plastik yang lebih kecil maka dari itu dilakukan peningkatan kekerasan pada material pisau pemotongnya, untuk meningkatkan material pisau pemotong dilakukan proses perlakuan panas. Perlakuan panas ini digunakan untuk meningkatkan kekerasan pada komponen pisau pemotong pada mesin pencacah plastik agar didapat kinerja pisau pemotong yang maksimal, metode perlakuan panas yang digunakan yaitu tempering dengan variasi temperatur 300°C, 400°C, dan 500°C. Data hasil pengujian kekerasan dengan metode vickers yang ditampilkan pada tabel dan grafik terlihat peningkatan kekerasan baja yang berbeda, selanjutnya dianalisa dan didapat nilai rata – rata kekerasan raw material sebesar 211 HV, kemudian baja yang ditempering dengan temperatur 300°C memiliki nilai kekerasan 257,73 HV, selanjutnya untuk tempering dengan temperatur 400°C memiliki nilai kekerasan 269,3 HV, dan untuk hasil tempering dengan temperatur 500°C memliki nilai kekerasan 250 HV. Untuk pengujian menggunakan struktur mikro terjadi perubahan struktur dari pearlite dan ferrite menjadi bainit dan martensite yang disebabkan oleh proses perlakuan panas pada spesimen uji.
Solar System Wave Function

Pluto, Ceres and all planets of Solar system except Neptune, with a high approximation, follow a rule called Titius-Bode rule or Bode rule, which can by no means be considered as a stochastic event. This rule shows that the distance of planets from the sun in Solar system is regulated. Here, I prove that the existence of a standing and cosine wave packet, with the wavelength λ = 0.6 AU (AU represents the distance of Earth from the Sun) and the phase constant ∅=π/6, in solar system is the reason for Bode rule. And moreover, I prove that this huge wave packet belongs to the sun. Bode rule does not predict the distance of Neptune from the Sun but, this article is able to give us the distance of Neptune. Based on this article, Quantum mechanics will enter into a new stage.

Bu çalışma, Batman’da Türkiye Grameen Mikrofinans Programı’na katılan kadınların kredileri ne amaçla kullandıkları bilgisinin yanı sıra onların program hakkındaki görüşlerini, borçluluk deneyimlerini ve yaşam koşullarını kadınların ağzından aktaracaktır. Küçük bir grup kadınla yapılan niteliksel bir araştırmaya dayanan çalışmanın ortaya çıkardığı bulgular, 2000’li yıllarda dünyada ve Türkiye’de giderek yaygınlaşan mikrokredi programlarının gerek söylemsel olarak gerekse de uygulamada neden bu kadar önem kazandığının sorgulanması gerektiğine işaret etmiştir. Mikrokredi programlarının bir parçası olduğu mikrofinans sektörünün büyümesi ve Türkiye’nin de arasında olduğu birçok devlet ve uluslararası kuruluş tarafından bizzat desteklenmesi kapitalizmin bugün ancak finansal genişleme yoluyla varlığını sürdürebiliyor olması ile yakından ilgilidir. Çoğu kere yoksullukla mücadele amacını güttüğünü iddia eden mikrokredi programları ayrıca devletlerin halklarına karşı sahip oldukları birçok yükümlülükten sıyrılmalarını öngören neoliberal yönetim mantığı ile de iyi bir uyum içerisindedir. Batman’da mikrokredi kullanan kadınlarla yapılan görüşmelere dayanan bu araştırma neoliberalizmle birlikte devletin nasıl dönüştüğü üzerine düşünmemize imkân tanımış ve devletin, ekonominin ve yönetim mantığının değiştiği bu dönüşümde kadınlara ne tür rol ve fonksiyonlar biçildiğini daha açık bir şekilde görmemizi sağlamıştır.

Accessory sex glands of fifteen apparently healthy adult one-humped Camel bulls (OCB), Uda rams (UR) and Red Sokoto bucks (RSB) (Five per species) were collected from Sokoto metropolitan abattoir. They were then dissected out for routine histology using H&E. The size of muscularis and the number of secretory cells in the ampullary gland were observed to be highest in OCB, followed by UR and least in RSB. In the three species, the vesicular gland has tubular secretory glands and was separated into lobules by connective tissue trabeculae. Multiple acini were observed with an irregular folded lumen and were lined by simple columnar secretory cells. The prostate of OCB was observed to have highest amount of the interstitial connective tissues and rich in striated muscles which surround the lobules. Fibromuscular trabeculae extended into the parenchyma and most pronounced in OCB than other two species. The number of secretory acini appeared to be more in RSB than the other two species. The bulbourethral gland has numerous connective tissue and numerous trabeculae that originated from the capsule and divides the gland into lobules. Each lobule is populated by acini. In all the three species, the parenchyma is lobulated and consists of compound-tubulo-alveolar secretory end pieces. It was concluded that although results showed that the studied animals are different ruminant species, they exhibit some similarities and interesting histomorphological differences in their accessory sex glands compared to the majority of mammals
