An Experimental Investigation the Optimum of Salinity and Ph of Sea-Water to Improve Oil Recovery from Sandstone Reservoir as A Secondary Recovery Process
Authors: Naser Madi Abdullah , Samba Mohammed A , Li Yiqiang
Published: December 2020

Laboratory tests and field applications shows that the salinity of water flooding could lead to significant reduction of residual oil saturation. There has been a growing interest with an increasing number of low-salinity water flooding studies. However, there are few quantitative studies on seawater composition change and it impact on increasing or improving oil recovery.  This study was conducted to investigate only two parameters of the seawater (Salinity and pH) to check their impact on oil recovery, and what is the optimum amount of salinity and ph that we can use to get the maximum oil recovery.  Several core flooding experiments were conducted using sandstone by inject seawater (high, low salinity and different pH). The results of this study has been shown that the oil recovery increases as the injected water salinity down to 6500 ppm and when the pH is around 7. This increase has been found to be supported by an increase in the permeability. We also noticed that the impact of ph on oil recovery is low when the pH is less than 7.
Analysis Study Of The Effect In Selecting Combination Of Fracturing Fluid Types And Proppant Sizes On Folds Of Increase (FOI) To Improve Well Productivity
Authors: Ramadhan Dimas , Tulloh Hidayat , Julianto Cahyadi
Published: December 2020

As fracturing materials, fracturing fluid and proppant are two very important parameters in doing hydraulic fracturing design. The combination of fractuirng fluid and proppant selection is the main focus and determinant of success in the hydraulic fracturing process. The high viscosity of the fracturing fluid will make it easier for the proppant to enter to fill the fractured parts, so that the conductivity of the fractured well will be better and can increase the folds of increase (FOI) compared to fracturing fluid with lower viscosity (Economides, 2000). This research was conducted by using the sensitivity test method on the selection of fracturing fluid combinations carried out at the TX-01 well with various sizes of proppants (namely; 12/18, 16/20, and 20/40 mesh) with the proppant selected being ceramic proppant type carbolite performed using the FracCADE simulator. Fracturing fluid was selected based on its viscosity, namely YF240OD and PrimeFRAC20 fluids with viscosity value of 4.123 cp and 171.1 cp, with a fixed pump rate of 14 bpm. The results showed that the combination of high-viscosity fluids (PrimeFRAC20) and 16/20 mesh proppant size resulted in a greater incremental fold (FOI) between the choice of another combination fracturing fluids and proppant sizes, namely 6.25.

“I Had No Idea That Other People in the World Thought Differently to Me”: Ethical Challenges in Small Animal Veterinary Practice and Implications for Ethics Support and Education
Authors: Richards Leonie , Coghlan Simon , Delany Clare
Published: December 2020

Although veterinarians encounter ethical challenges in their everyday practice, few studies have examined how they make sense of and respond to them. This research used semi-structured interviews and a qualitative methodology (phenomenological and constructivist/interpretivist approaches) to explore ethical challenges experienced by seven small animal city veterinarians and their ethical decision-making strategies. Thematic analysis of the interview transcripts identified four broad ethical issues: The first concerned disagreements about the best interests of the animal; the second centered on clinical uncertainty about the most appropriate treatment for the animal; the third involved factors influencing ethical reasoning and decision making; and the fourth concerned how ethics education might prepare veterinary students for future ethical decision making. An overarching theme identified in the analysis was one of enormous personal distress. Furthermore, a sense of veterinarians being interested in how others might think and feel about ethical challenges came through in the data. The results give insight into how veterinarians experience and respond to ethical challenges. The research also provides empirical information about everyday practice to inform future education in ethics and ethical decision making for veterinary students.
Influence of Case Hardening Process and Hardenability on the Distortion Behavior of a Weight-Reduced Counter Gear
Authors: Lübben Th. , Kagathara J.
Published: December 2020

Objectives in the field of lightweight construction can be achieved by changing the component design, among other things. However, a design suitable for production would have to be taken into account, since serious distortion problems can occur after the final heat treatment due to reduced stiffness or asymmetries in the mass distribution. To illustrate this problem area, this paper first of all presents the distortion behavior of various geometric modifications with mass reductions of up to 43.6 % at a specified case-hardening process using the example of a counter gear made of 20MnCr5. The goal for the geometry modifications was only the variation of the distortion potential carrier mass distribution. Insufficient dimensioning for a correct functional behavior was consciously accepted. In a second block, the influences of variations of the quenching process, the carbon profile and hardenability are presented for the lightest geometry variant.
Investigation of Parameters Influencing the Hardening Distortion of Driving Bevel Gears
Authors: Moriße S. , Hoffmann F. , Lübben Th. , Herbold K.
Published: December 2020

From an economic and ecological point of view, mastering the distortion behavior of gear components continues to represent a considerable potential for reducing reworking and scrap costs. In particular, the constraints arising in the course of electrification, for rapid implementation of drive solutions that are as CO2-neutral as possible, require leaner processes. Within the scope of this work, investigations were carried out to identify parameters influencing the hardening distortion of drive bevel gears. The primary goal was to identify influences and disturbance variables in a standard large series process that have to be either eliminated or controlled in order to ensure consistent delivery quality with the most constant lapping settings possible, especially during the final lapping process, in which crown wheel and drive bevel gear are „married“. This publication presents the experimental results of investigations on drive bevel gears from 41 melt batches under near-series case hardening with oil quenching as well as a heat treatment experiment with intermediate stress relief annealing and a third series of tests in which case hardening is carried out in a low-pressure carburizing plant with varied heating rate, temperature holding stages and high-pressure gas quenching.

Is It Really a “Mothers’ Hell”? On Motherhood in the Dramas of Maria Pawlikowska-Jasnorzewska
Authors: Warońska Joanna
Published: December 2020

The author draws attention to the complexity of motherhood as one of the themes depicted in the dramatic works of Wojciech Kossak’s older daughter. Considered a moderate feminist in the interwar period, Pawlikowska-Jasnorzewska is aware of the fact that having children has become a public matter. It is in the interest of the family, the species and society in general. For this reason, legal regulations are likely to create oppressive situations in which women’s interests and rights are dismissed. In Pawlikowska-Jasnorzewska’s plays, the topic of motherhood appears in a variety of circumstances, and the news about pregnancy often transforms into a touchstone situation, sparking a debate on the rights and obligations of an individual towards the human species and their family. Abortion is one of the possible solutions. Yet, while criticising the system of norms and imperatives evolved around the instinct of having children, the playwright focuses on the positive images of motherhood. Good mothers are happy, while bad mothers are condemned. Therefore, while granting the heroines of her plays the right to love and personal fulfilment, Pawlikowska-Jasnorzewska remains a traditionalist when it comes to obligations towards a conceived child.
„Teraz, myślę, ale wcale nie”1 Zdrój Barbary Klickiej jako narracja maladyczna
Authors: Kotuła Dominika
Published: December 2020

This article presents Barbara Klicka’s novel Zdrój as an example of an illness narrative.The novel is discussed in the context of both other examples of the genre and the theoretical works devoted to the topic. The fact she is experiencing illness determines the protagonist’s existence and her perception of the world. It influences her emotions. As a hypersensitive individual, she is ableto recognise the mechanisms of oppression embedded in the process of treatment, such as the objectification of patients. The narrator’s status is peculiar – she is not losing the battle with her illness, neither is she recovering. She is a “wounded storyteller,” remaining in a liminal state. Illness is one of the essential elements of the protagonist’s identity, and not simply the theme of her story but rather a condition without which the story would not exist.

This article shows the functioning of the social image of the victim and describes a particular attempt to overcome it, based on Halszka Opfer’s autobiographical books and Katarzyna Surmiak-Domańska’s reportage. This triptych proves that the adopted perspective determines the reading of the text and how difficult it is to break free from the social, as well as one’s own, framework.
Shutting Down Sex
Authors: McKenzie Lara
Published: December 2020

This article examines the transformation of singledom during the COVID-19 pandemic, scrutinising the impact of rules and regulations governing proximity, touch and sex. I focus on government responses in Australia, situating the nation’s experience in a global context. National discussions were strangely sexless, presuming widespread coupledom and emphasising the lost, non-sexual intimacies of families and older people. I contrast this to broader theoretical claims of a ‘transformation of intimacy’ that posit a move to atomised relations across the Global North, including a growing tendency towards singledom. Yet assumptions of coupledom clearly persist in Australian policy and social life. I reflect on transformations of singledom and living alone during and prior to the pandemic, exposing tensions between theorisations, local realities, and the governance of sex and singledom.
Haptic Mediations
Authors: Simpson Bob
Published: December 2020

During the COVID-19 crisis, living in lockdown and observing social distancing rules have become an integral part of everyday life. In this article, I offer some auto-ethnographic reflections on the increased use of ICTs within families and particularly across generations. Using vignettes relating to communication with my one-year-old granddaughter and my 92-year-old mother, I consider what it means to have the haptic dimensions of kinship relations stripped out and replaced by technologically mediated connection. By way of conclusion, I consider the relationship between the ‘magic’ of ICTs in interpersonal communication on the one hand and Marshall Sahlins’ notion of mutuality on the other.
Child Protection Social Work in COVID-19
Authors: Pink Sarah , Ferguson Harry , Kelly Laura
Published: December 2020

This article brings together digital anthropology and social work scholarship to create an applied anthropology of everyday digital intimacy. Child protection social work involves home visits in the intimate spaces of others, where modes of sensorial and affective engagement combine with professional awareness and standards to constitute sensitive understandings of children’s well-being and family relationships. In the COVID-19 pandemic, social work practice has shifted, partly, to distance work where social workers engage digitally with service users in their homes while seeking to constitute similarly effective modes of intimacy and understanding. We bring practice examples from our study of social work and child protection during COVID-19 together with anthropologies of digital intimacy to examine implications for new modes of digital social work practice.
Viral Intimacy and Catholic Nationalist Political Economy
Authors: Whyte David
Published: December 2020

Changes in the conduct and regulation of intimacy during the COVID-19 crisis in the Republic of Ireland has uncovered the legacy of Catholic nationalism in Irish capitalism. Many commentators analysed the increased welfarism and community service provision as the suspension of Irish neoliberalism. In fact, the Irish COVID-19 response is shaped by a longer tradition of political and economic approaches that have their genesis in the revolutionary Catholic state following independence from Britain. Based on ethnography of community development practices in a rural Irish region, the article describes how Catholic nationalist influences are present in the collection of institutions involved in the Community Response and its approach to spatial organisation. The governance of the response also sheds light on a lack of intimacy between citizen and state that is not only the product of neoliberal structural adjustments but is uniquely characteristic of the Catholic ethos that influences Irish capitalism.
Lockdown Reflections on Freedom and Cultural Intimacy
Authors: Herzfeld Michael
Published: December 2020

In this article I address the role now being played by libertarian attacks on the enforcement of health regulations such as the wearing of masks. I suggest that a kind of cultural intimacy now emerging may take the form of guilty but willful complicity in a libertarian stance, not for reasons of social solidarity or collective freedom but for a NIMBY-like selfishness. That attitude constitutes a larger threat to society and is cultivated by racist and other hate-directed groups often sheltering behind bullying national leaders. These groups adopt the libertarian rhetoric and nationalist tropes of concern to protect individual freedoms, whether in the United States or the United Kingdom. The article ends with an appeal for anthropologists, in particular, to respond by framing a more socially conscious vision of freedom.
Intimacy with God and Coronavirus in Pakistan
Authors: Malik Nadeem
Published: December 2020

Intimacy with God is at the heart of Islamic practice through prayer. Intimacy with fellow congregants became central to the worship practices promoted by religious leaders during the holy month of Ramadan even when social distancing was required because of the pandemic. This was, by and large, an economic matter. Clerics and mosques rely significantly on the income generated through collective worship, especially during Ramadan. This article provides an account of people’s sense of intimacy with God and fellow congregants during Ramadan and how it contributed to the spread of the coronavirus in Pakistan.

Bullying Prevention and School Climate: Correlation between Teacher Bullying Prevention Efforts and their Perceived School Climate
Authors: Baraldsnes Dziuginta
Published: December 2020

This study investigates the correlation between teachers’ efforts to prevent bullying and their perceptions of school climate. The quantitative data were collected from 82 teachers (76.8%females, respondents’ mean age = 44.91 years [SD = 9.91]) from 13 Norwegian schools running the Olweus Bully Prevention Program (OBPP). Descriptive analysis of the teachers’ efforts within OBPP at the school, classroom, and individual levels, and simple linear as well as multiple regression analyses were applied. The current study revealed that teachers acted differently within OBPP at the school, classroom, and individual levels, and that their perceptions of school climate differed. A significant positive correlation was found between the teachers’ efforts within OBPP at the all-level variable and the general school climate variable. Implications for the teachers’ efforts to prevent school bullying through OBPP and the significance of the study results for the whole school community are discussed, and limitations of the current study are pointed out.

Authors: Shahzad Imran Ahmed , Farrukh Muhammad , Wu Yihua , Trunk Nada
Published: December 2020

BACKGROUND: For augmentation and sustainability of Human Systems Management (HSM), it is significant to analyse and reposition journals, which is very well done by bibliometric analysis. OBJECTIVE: The study aims to provide the retrospective of HSM between 1980– 2019. METHOD: Scopus database has been employed to bibliographic indicators for the representation of available data for forty years. By utilising the VOSviewer software, bibliographic materials being drawn from keywords, graphical visuals, bibliographic coupling & co-citation analysis have been done. RESULTS: Results enabled to establish that the average number of publications remained almost the same throughout forty years, tinting the journal has been as vital in 2019 for researchers as it was in 1980. Citations originated drastic mounting with recently published documents in comparison with earlier production. CONCLUSIONS: Authors and researchers are suggested to cover knowledge and knowledge management related articles. This study suggests management to ensure the inculcation of more related areas in the scope by announcing special issues to broaden the journals’ scope as it remained the main reason for limiting HSM from gaining as much attention as it deserved.
Image-based textile decoding
Authors: Chen Siqiang , Toyoura Masahiro , Terada Takamasa , Mao Xiaoyang , Xu Gang
Published: December 2020

A textile fabric consists of countless parallel vertical yarns (warps) and horizontal yarns (wefts). While common looms can weave repetitive patterns, Jacquard looms can weave the patterns without repetition restrictions. A pattern in which the warps and wefts cross on a grid is defined in a binary matrix. The binary matrix can define which warp and weft is on top at each grid point of the Jacquard fabric. The process can be regarded as encoding from pattern to textile. In this work, we propose a decoding method that generates a binary pattern from a textile fabric that has been already woven. We could not use a deep neural network to learn the process based solely on the training set of patterns and observed fabric images. The crossing points in the observed image were not completely located on the grid points, so it was difficult to take a direct correspondence between the fabric images and the pattern represented by the matrix in the framework of deep learning. Therefore, we propose a method that can apply the framework of deep learning viau the intermediate representation of patterns and images. We show how to convert a pattern into an intermediate representation and how to reconvert the output into a pattern and confirm its effectiveness. In this experiment, we confirmed that 93% of correct pattern was obtained by decoding the pattern from the actual fabric images and weaving them again.
Learning to combine classifiers outputs with the transformer for text classification
Authors: Bugueño Margarita , Mendoza Marcelo
Published: December 2020

Text classification is a fairly explored task that has allowed dealing with a considerable amount of problems. However, one of its main difficulties is to conduct a learning process in data with class imbalance, i.e., datasets with only a few examples in some classes, which often represent the most interesting cases for the task. In this context, text classifiers overfit some particular classes, showing poor performance. To address this problem, we propose a scheme that combines the outputs of different classifiers, coding them in the encoder of a transformer. Feeding also a BERT encoding of each example, the encoder learns a joint representation of the text and the outputs of the classifiers. These encodings are used to train a new text classifier. Since the transformer is a highly complex model, we introduce a data augmentation technique, which allows the representation learning task to be driven without over-fitting the encoding to a particular class. The data augmentation technique also allows for producing a balanced dataset. The combination of both methods, representation learning, and data augmentation, allows improving the performance of trained classifiers. Results in benchmark data for two text classification tasks (stance classification and online harassment detection) show that the proposed scheme outperforms all of its direct competitors.
sKAdam: An improved scalar extension of KAdam for function optimization
Authors: Camacho J.D. , Villaseñor Carlos , Alanis Alma Y. , Lopez-Franco Carlos , Arana-Daniel Nancy
Published: December 2020

This paper presents an improved extension of the previous algorithm of the authors called KAdam that was proposed as a combination of a first-order gradient-based optimizer of stochastic functions, known as the Adam algorithm and the Kalman filter. In the extension presented here, it is proposed to filter each parameter of the objective function using a 1-D Kalman filter; this allows us to switch from matrix and vector calculations to scalar operations. Moreover, it is reduced the impact of the measurement noise factor from the Kalman filter by using an exponential decay in function of the number of epochs for the training. Therefore in this paper, is introduced our proposed method sKAdam, a straightforward improvement over the original algorithm. This extension of KAdam presents a reduced execution time, a reduced computational complexity, and better accuracy as well as keep the properties from Adam of being well suited for problems with large datasets and/or parameters, non-stationary objectives, noisy and/or sparse gradients.
Development of Children’s Religiousity in Dual Career Family
Authors: Iswati Iswati
Published: December 2020

This study aimed to describe the development of children's religious life from a family of dual career families, namely families where both father and mother both work outside the home and undergo certain professions. How is the parenting style and pattern of education applied by parents to keep the child's awareness and religious attitudes in good condition, and what factors are the supporters and inhibitors of the development of a child's religious spirit in the dual career family ?. Child restrictions referred to in this study are children in the range of primary school age, namely between the ages of 7-11 years. Based on data collected from 6 families of working mothers' fathers who are respondents, the results of the study show that families generally realize that parents are still the first and foremost place for child growth and development, so that the main function of the family is not to be educated, caring, socializing children so that children can carry out their functions in society properly, remains a top priority. Parenting that is applied in the family is generally appropriate, namely democratic parenting and education patterns as a place to socialize the ideal second child, namely the school environment that has an orientation on spiritual development in addition to academic orientation. While the supporting and inhibiting factors of the process of developing mindfulness in children are generally influenced by the internal and external factors of children, the school environment, the community and most importantly parents.
The Principal’s Effective Leadership in Elementary Education
Authors: Hadi Mukhtar
Published: December 2020

The importance of effective management in educational organizations is getting more and more attention from various parties. The purpose of this study was to find out whether the heads of Madrasah Ibtidai'yah in Metro City had implemented effective leadership patterns in leadership management in madrasah. The results of this study indicate that the heads of Islamic elementary schools in Metro City are actually principals who present themselves as effective leaders and understand well how to become professional leaders. The professional meaning here is that the head of the madrasah has shown itself to be an education leader and always maintains quality at all times. In certain circumstances the head of the madrasah has even included the category of master school leaders who are able to show quality where other parties can place the principal as an expert in leading the school. The principal not only looks good, but also is able to show understanding of the meaning of quality. However, there has not been seen any influence between the headmaster's leadership and the level of achievement achieved by students. This means that principals actually include educational leaders with the title of professionals or even masters, but there is no significant influence between the level of leadership and student achievement.

Authors: Zafi Ashif Az
Published: December 2020

Era disrupsi memberi pengaruh terhadap perkembangan lembaga pendidikan Islam tingkat dasar. Lembaga pendidikan Islam tingkat dasar semakin banyak yang memasukkan program ibadah sebagai program unggulannya guna membentuk peserta didik yang Islami. Namun ini menimbulkan permasalahan tersendiri karena peserta didik tingkat dasar belum mampu berpikir abstrak sehingga sampai pada penghayatan. Padahal ibadah yang dilakukann harus dihayati. Penelitian ini bermaksud untuk mengetahui bagaimana pemahaman dan penghayatan peserta didik tentang ibadah di MI NU Manafiul Ulum Gebog Kudus. Penelitian ini termasuk penelitian kualitatif. Tujuan dilakukan penelitian ini adalah untuk mengetahui apa saja pengamalan ibadah peserta didik dan bagaimana pemahaman serta penghayatan peserta didik tentang ibadah yang dilaksanakannya. Hasil dari penelitian ini adalah ibadah yang diajarkan dan dibiasakan kepada peserta didik adalah salat, puasa, doa harian, membaca dan menghafal Al Quran. Pemahaman peserta didik tentang pengamalan ibadah sudah paham mengenai hukumnya seperti wajib, sunah, dosa, pahala, surga dan neraka. Namun peserta didik belum memahami tentang tujuan dan manfaat ibadah yang dilaksanakannya. Menariknya, pengamalan ibadah peserta didik tergolong taat dan sudah menjadi kebiasaan sehari-hari. Ini menunjukkan bahwa pengamalan ibadah peserta didik sudah menjadi kepribadian (being/tindakan moral) namun masih lemah dalam pemahaman (pengetahuan moral) dan belum mencapai kesadaran (perasaan moral).
