PERANCANGAN TAMAN OLAHRAGA DI KELAPA GADING
Authors: Septiani Devi , Winata Tony
Published: July 2020

Reduced public open space due to competition in urban areas has resulted in reduced community gathering activities (third place). Many big cities in Indonesia are aggressively building new parks or revitalizing old parks, like in the city of Jakarta. This is because the population density reaches 15,663 people / km2. The population continues to grow from 4.5 million people (1970) to double that, which is 9.6 million in 2010, while now it has reached 10.4 million people and is estimated to be 11-15 million by 2020-2030. As a result, almost all of the surface of the city has been devoured by buildings and changed the function of its designation Kelapa Gading sub-district with an area of 161.21 ha, this district has several shopping centers whose area exceeds the existing green space, namely, an area of 996,215 m2, through the results of observational studies that have been carried out then a proposed project that can meet the needs of the ivory coconut community for a healthy lifestyle with limited land as a means of sports that can accommodate various groups of people. Not only as a sports facility, but as a recreational facility and container that can accommodate interactions in the ivory coconut community. By looking at the parameters that exist in designing the third space, this design is adjusted to the ivory community's need for public space as the third space. AbstrakBerkurangnya ruang terbuka publik akibat persaingan lahan di perkotaan mengakibatkan berkurangnya aktivitas berkumpul bagi masyarakat (third place). Banyak kota – kota besar di Indonesia yang gencar untuk membangun taman baru atau merevitalisasi taman lama, seperti di Kota Jakarta. Hal ini dikarenakan tingkat kepadatan penduduk yang mencapai 15.663 jiwa/km2. Populasi terus bertambah dari 4.5 juta jiwa (1970) hingga menjadi dua kali lipatnya, yaitu 9.6 juta pada tahun 2010, sedangkan sekarang telah mencapai 10.4 juta orang dan diperkirakan untuk menjadi 11 – 15 juta pada tahun 2020 – 2030 mendatang. Akibatnya hampir seluruh permukaan kota telah habis dimakan bangunan dan berubah fungsi peruntukannya Kecamatan Kelapa gading dengan luasan wilayah 161,21 ha, kecamatan ini memiliki beberapa pusat perbelanjaan yang luasnya melebihi RTH yang ada yaitu, seluas 996.215 m2, melalui hasil studi observasi yang telah dilakukan maka diusulkan proyek yang dapat memenuhi kebutuhan masyarakat kelapa gading akan gaya hidup yang sehat dengan lahan yang terbatas sebagai sarana olahraga yang dapat menampung berbagai kalangan maasyarakat. Tidak hanya sebagai sarana olahraga, tetapi sebagai sarana rekreasi dan wadah yang dapat menampung terjadinya interaksi dalam masyarakat kelapa gading. Dengan melihat parameter yang ada dalam mendesain ruang ketiga maka rancangan ini disesuaikan dengan kebutuhan masyarakat kelapa gading akan ruang publik sebagai ruang ketiga.
WADAH AKTIVITAS DAN KOMUNITAS DI CENGKARENG, JAKARTA
Authors: Valencia Angel
Published: July 2020

Cengkareng is a district with the highest number of migrants in Jakarta and with a dense population. Enabling new communities to come. The lack of facilities is facilitated for third place residents of Cengkareng so residents often spend free time to gather next to the cemetery. Mushollah is a gathering place for residents to worship or just spend time together .hird place for the city community functions as a space between the living space and work space. Third place helps urban people to be humanistic, open, dynamic and productive. Humans as social beings need social interaction in living life. With the existence of a community forum building and activities that function as a forum for social interaction for the people of Cengkareng, it can make the local residents get to know each other and know about the activities in Cengkareng. Then it can reduce the problems of individualism and vandalism that are in Cengkareng. The building design will be based on the three main functions of the building, namely social, recreational and education with the concept of the building placing the plaza as the main link connected with these functions. It is hoped that this building can be useful for the community to deal with a new sense of boredom, open up new perspectives and interact with new people. Abstrak Cengkareng merupakan kecamatan dengan jumlah pendatang tertinggi di Jakarta dan dengan jumlah penduduk yang padat. Memungkinkan adanya komunitas-komunitas baru yang akan hadir. Kurangnya terfasilitasi tempat third place bagi warga Cengkareng sehingga warga sering menghabiskan waktu luang untuk berkumpul di sebelah pemakaman. Mushollah menjadi tempat berkumpul warga untuk beribadah atau sekedar menghabiskan waktu bersama.Third place bagi masyarakat kota berfungsi sebagai ruang antara ruang yang tempat tinggal dan ruang tempat bekerja. Third place membantu masyarakat kota agar bersifat humanis, terbuka, dinamis dan produktif. Manusia sebagai makhluk sosial membutuhkan interaksi sosial dalam menjalani kehidupan. Dengan adanya bangunan wadah komunitas dan aktivitas yang berfungsi sebagai wadah interaksi sosial bagi masyarakat Cengkareng dapat membuat warga sekitar untuk saling mengenal dan mengetahui mengenai kegiatan yang ada di Cengkareng. Kemudian dapat mengurangi adanya masalah individualisme dan vandalisme yang berada di Cengkareng. Desain bangunan akan berpacu pada tiga fungsi utama bangunan yaitu sosial, rekreasi dan edukasi dengan konsep bangunan meletakan plaza menjadi penghubung utama yang terkoneksi dengan fungsi-fungsi tersebut. Diharapkan bangunan ini dapat bermanfaat bagi masyarakat untuk kebaruan mengatasi rasa kebosanan, membuka sudut pandang perspektif baru dan dapat berinteraksi berkenalan dengan orang baru.
Image steganography based on DNA sequence translation properties

Published: July 2020

Digital communication has become a vital part of daily life nowadays, many applications are using internet-based communication and here the importance of security rose to have a secure communication between two parties to prevent authorized access to sensitive data. These requirements led to a number of research in information security that has been done in the past two decades. Cryptography and steganography are the two main methods that are being used for information security. Cryptography refers to techniques that encrypt a message to be sent to a destination using different methods to be done. On the other hand, steganography is the science of hiding information from others using another cover message or media such as image, audio, video, and DNA sequence. This paper proposed a new method to hide information in an image using the least significant bit (LSB) based on Deoxyribonucleic Acid (DNA) sequence. To accomplish this, the proposed scheme used properties of DNA sequence when codons that consist of three nucleotides are translated to proteins. The LSB of two pixels from the image are taken to represent a codon and then translate them to protein. The secret message bits are injected into codons before the translation process which slightly distorts the image and makes the image less suspicious and hard to detect the hidden message. The experimental results indicate the effeteness of the proposed method.
A "variatio" no mito de Eco e Narciso, nas "Metamorfoses" de Ovídio, como exercício de um poeta "lascivus"
Authors: Nascimento Dreykon Fernandes , Leite Leni Ribeiro , Paulino da Silva Camilla Ferreira
Published: July 2020

Quintiliano, em diversas passagens da sua Institutio oratoria (4.1.77; 10.1.88-9; 10.1.93), categoriza Ovídio e as suas obras de serem excessivamente lascivi. Diferentemente de Horácio, contudo, que exercia a crítica literária enquanto ocupava também o lugar social de poeta no principado augustano, Quintiliano a exerce em posição exclusiva de orador, em nome de uma instituição retórica sólida e voltada majoritariamente para o fórum público. Assim, não crendo ser lascivus apenas um vocábulo cujo significado é facilmente localizável num dicionário de língua latina, investigamos no presente trabalho o valor objetivamente retórico subjacente ao termo, e se é adequado ou não à obra ovidiana, analisando a variatio ou a variação genérica trabalhada por Ovídio, sobretudo, no mito de Eco e Narciso, presente no canto 3 das Metamorfoses. Para tal, aparelhamo-nos com estudos de Barchiesi (2006), Farrell (2009), Fedeli (2010), Fonseca (2015), Feldherr (2006), Harrison (2006), Hutchinson (2013), Keith (2002), Oliva Neto (2013), Pavlock (2009) Perutelli (2010), Vansan (2016) entre outros sobre o uso dos gêneros poéticos em Ovídio, e com estudos de Feldherr (2006) e Fox (2007) sobre a relação entre retórica e literatura, a posição de Quintiliano e sob que instância de poder fala quando rotula Ovídio de lascivus.
A caracterização das Danaides nas Suplicantes de Ésquilo
Authors: De Paoli Beatriz
Published: July 2020

As "Suplicantes", de Ésquilo, tragédia representada em torno de 463 a.C., narra a história das cinquenta filhas de Dânao, que,fugindo de sua pátria, o Egito, chegam a Argos, terra de sua ancestral Io, buscando asilo e proteção. As jovens chegam fugindo de seus primos, os Egipcíades, que pretendem desposá-las à força. O objetivo deste artigo é discorrer sobre alguns aspectos da caracterização das Danaides nessa tragédia esquiliana, tendo como fio condutor o par de opostos gregos-bárbaros e procurando observar em que medida essa caracterização cria aquilo que Hartog (1980) denomina de “efeito de alteridade” e esse “efeito de alteridade” está a serviço de uma representação majoritariamente pejorativa dos bárbaros.

Published: July 2020

The vanadium redox flow battery (VRFB) is a promising energy storage technology for stationary applications (e.g., renewables integration) that offers a pathway to cost-effectiveness through independent scaling of power and energy as well as longevity. Many current research efforts are focused on improving battery performance through electrode modifications, but high-throughput, laboratory-scale testing can be time- and material-intensive. Advances in multiphysics-based numerical modeling and data-driven parameter identification afford a computational platform to expand the design space by rapidly screening a diverse array of electrode configurations. Herein, a 3D VRFB model is first developed and validated against experimental results. Subsequently, a new 2D model is composed, yielding a computationally-light simulation framework, which is used to span bounded values of the electrode thickness, porosity, volumetric area, fiber diameter, and kinetic rate constant across six cell polarization voltages. This generates a dataset of 7350 electrode property combinations for each cell voltage, which is used to evaluate the effect of these structural properties on the pressure drop and current density. These structure-performance relationships are further quantified using Kendall $\tau$ rank correlation coefficients to highlight the dependence of cell performance on bulk electrode morphology and to identify improved property sets. This statistical framework may serve as a general guideline for parameter identification for more advanced electrode designs and redox flow battery (RFB) stacks.
Can Polarity-Inverted Surfactants Self-Assemble in Nonpolar Solvents?
Authors: Carrer Manuel , Skrbic Tatjana , Bore Sigbjørn Løland , Milano Giuseppe , Cascella Michele , Giacometti Achille
Published: July 2020

We investigate the self-assembly process of a surfactant with inverted polarity in water and cyclohexane using both all-atom and coarse grained hybrid particle-field molecular

dynamics simulations. Unlike conventional surfactants, the molecule under study proposed in a recent experiment is

formed by a rigid and compact hydrophobic adamantane moiety, and a long and floppy triethylene glycol tail. In water, we report the formation of stable inverted micelles with the adamantane heads grouping together into a hydrophobic core, and the tails forming hydrogen bonds with water. By contrast, multi-microsecond simulations do not provide evidence of stable micelle formation in cyclohexane. Validating the computational results by comparison with experimental diffusion constant and small-angle neutron scattering intensity, we show that at laboratory thermodynamic conditions the mixture resides in the supercritical region of the phase diagram, where aggregated and free surfactant states co-exist in solution. Our simulations also provide indications about how to escape this region, to produce thermodynamically stable micellar forms.

The atomic structure and local composition of high quality epitaxial substoichiometric titaniumdiboride (TiB1.9) thin film, deposited by unbalanced magnetron sputtering, were studied usinganalytical high-resolution scanning transmission electron microscopy, density functional theoryand image simulations. The unmatched Ti is pinpointed to planar defects on {1-100} prismaticplanes and attributed to the absence of B between Ti planes that locally relaxes the structure.This mechanism allows the line compound to accommodate the off-stoichiometry and remaina line compound between defects. The planar defects are embedded in otherwise stoichiometricTiB2 and are delineated by insertion of dislocations. An accompanied decrease in Ti-Ti bondlengths along and across the faults is observed.Introduction

The SARS-CoV-2 outbreak has spread rapidly and globally generating a new coronavirus disease (COVID-19) since December 2019 that turned into a pandemic. Effective drugs are urgently needed and drug repurposing strategies offer a promising alternative to dramatically shorten the process of traditional de novo development. Based on their antiviral uses, the potential affinity of sea urchin pigments to bind main protease (Mpro) of SARS-CoV-2 was evaluated in silico. Docking analysis was used to test the potential of these sea urchin pigments as therapeutic and antiviral agents. All pigment compounds presented high molecular affinity to Mpro protein. However, the 1,4-naphtoquinones polihydroxilate (Spinochrome A and Echinochrome A) showed high affinity to bind around the Mpro´s pocket target by interfering with proper folding of the protein mainly through an H-bond with Glu166 residue. This interaction represents a potential blockage of this protease´s activity. All these results provide novel information regarding the uses of sea urchin pigments as antiviral drugs and suggest the need for further in vitro and in vivo analysis to expand all therapeutic uses against SARS-CoV-2.
Modulation of Immune Cell Reactivity with Cis-Binding Siglec Agonist
Authors: Delaveris Corleone , Chiu Shannon , Riley Nicholas , Bertozzi Carolyn
Published: July 2020

Primary inflammatory pathologies caused by phagocytes lead to numerous debilitating conditions, including chronic pain and blindness due to age-related macular degeneration. Many members of the sialic acid-binding immunoglobulin-like lectin (Siglec) family are immunoinhibitory receptors whose agonism is an attractive approach to for anti-inflammatory therapy. Here, we show that synthetic lipid-conjugated glycopolypeptides can insert into cell membranes and engage Siglec receptors in cis, leading to inhibitory signaling. Specifically, we construct a cis-binding agonist of Siglec-9 and show that it modulates MAPK signaling in reporter cell lines, immortalized macrophage and microglial cell lines, and primary human macrophages. These cis-binding agonists of Siglecs present a new modality for therapeutic suppression of immune cell reactivity.

ENVIRONMENTAL FLOW AND CONTAMINANT TRANSPORT MODELING IN THE AMAZONIAN WATER SYSTEM BY USING Q3DRM1.0 SOFTWARE
Authors: Yu Li-ren , Yu Jun
Published: July 2020

This paper reports a fine numerical simulation of environmental flow and contaminant transport in the Amazonian water system near the Anamã City, Brazil, solved by the Q3drm1.0 software, developed by the Authors, which can provide the different closures of three depth-integrated two-equation turbulence models. The purpose of this simulation is to refinedly debug and test the developed software, including the mathematical model, turbulence closure models, adopted algorithms, and the developed general-purpose computational codes as well as graphical user interfaces (GUI). The three turbulence models, provided by the developed software to close non-simplified quasi three-dimensional hydrodynamic fundamental governing equations, include the traditional depth-integrated two-equation turbulence   model, the depth-integrated two-equation turbulence model, developed previously by the first Author of the paper, and the depth-integrated two-equation turbulence   model, developed recently by the Authors of this paper. The numerical simulation of this paper is to solve the corresponding discretized equations with collocated variable arrangement on the non-orthogonal body-fitted coarse and fine two-levels’ grids. With the help of Q3drm1.0 software, the steady environmental flows and transport behaviours have been numerically investigated carefully; and the processes of contaminant inpouring as well as plume development, caused by the side-discharge from a tributary of the south bank (the right bank of the river), were also simulated and discussed in detail. Although the three turbulent closure models, used in this calculation, are all applicable to the natural rivers with strong mixing, the comparison of the computational results by using the different turbulence closure models shows that the turbulence   model with larger turbulence parameter provides the possibility for improving the accuracy of the numerical computations of practical problems.

Authors: Buliga Venance , Rongo Larama MB , Mamuya Simon HD
Published: July 2020

Background: Small scale sunflower oil industries are industries which extract oil from sunflower seed. Apart from its contribution to the economic development of the nation, during extraction process much dust concentration produced and respiratory symptoms are unknown. The aim of study was to assess dust exposure and associated respiratory health symptoms among small scale sunflower oil industries workers in Singida Tanzania. Methods: A cross sectional study was conducted and 233 participants were interviewed using a modified American Thoracic Society questionnaire to assess the respiratory health symptoms. A Side Kick Casella Pump was used to collect respirable dust from a sub sample of 66 workers from the sieving section. Results: Respirable dust exposure levels for mean, and Geometrical mean was 10.45 mg/m3 (SD 13.90) and GM=5.25 mg/m3 (GSD 0.51) respectively, and 46% of the dust samples (n=66) were above the TLV of 5 mg/m3. Logistic regression analysis between measured dust and respiratory symptoms found to be statistically significant.  Higher prevalence of respiratory health symptoms were seen in those with cough (33%), cough with phlegm (46.8%) and wheezy (41.6%). Conclusion: The study concludes that, respiratory symptoms were high and dust exposure was above recommended levels of 5 mg/m3. We recommend use of appropriate RPE.

Ethical Concerns of Human-Being, Cyber-Being and Cybertariat: An Educational Perspective
Authors: Sharan Raghubir , Boruah Bijoy
Published: July 2020

Few would deny that machines (along with intelligent machines) are a cultural creation of great significance. The Human race has shown extraordinary skills in achieving this glory. But this is not the glory of an unblemished modern humanity. While humankind has been admirably powerful in creatively controlling external forces, there has not been a similar display of control over the inner forces of selfish desire and the will to individual power. Education, it its true spirit, is a noble endeavour dedicated to a proper balancing of the external and the internal forces operative in the human psyche. The currently overwhelming prevalence of STEM education seems to be more aligned to the 'external' end of this spectrum of human drive, whereas the disciplines of the Humanities critically address themselves to the imminent problem of imbalance and are attuned to the pursuit of the 'internal' end. Whether we can hope for a future far better than the past, or fall into a state of despair by doing worse than our past, crucially depends on the extent to which higher education in contemporary times is wedded to the virtue of attaining the balance.

Using a Social-Ethical Framework to Evaluate Location-Based Services in an Internet of Things World
Authors: Abbas Roba , Michael Katina , Michael M.G.
Published: July 2020

The idea for an Internet of Things has matured since its inception as a concept in 1999. People today speak openly of a Web of Things and People, and even more broadly of an Internet of Everything. As our relationships become more and more complex and enmeshed, through the use of advanced technologies, we have pondered on ways to simplify flows of communications, to collect meaningful data, and use them to make timely decisions with respect to optimisation and efficiency. At their core, these flows of communications are pathways to registers of interaction, and tell the intricate story of outputs at various units of analysis- things, vehicles, animals, people, organisations, industries, even governments. In this trend toward evidence-based enquiry, data is the enabling force driving the growth of IoT infrastructure. This paper uses the case of location-based services, which are integral to IoT approaches, to demonstrate that new technologies are complex in their effects on society. Fundamental to IoT is the spatial element, and through this capability, the tracking and monitoring of everything, from the smallest nut and bolt, to the largest shipping liner to the mapping of planet earth, and from the whereabouts of the minor to that of the prime minister. How this information is stored, who has access, and what they will do with it, is arguable depending on the stated answers. In this case study of location-based services we concentrate on control and trust, two overarching themes that have been very much neglected, and use the outcomes of this research to inform the development of a socio-ethical conceptual framework that can be applied to minimise the unintended negative consequences of advanced technologies. We posit it is not enough to claim objectivity through information ethics approaches alone, and present instead a socio-ethical impact framework. Sociality therefore binds together that higher ideal of praxis where the living thing (e.g. human) is the central and most valued actor of a system.
The Right to Nonparticipation for Global Digital Citizenship
Authors: Iliadis Andrew
Published: July 2020

This article argues for the right to nonparticipation for Global Digital Citizenship (GDC). It recuperates the notion of political nonparticipation in the context of information and communication technologies (ICTs) and GDC in order to show that nonparticipation can operate effectively in non-State spheres, particularly online. The paper begins with a discussion of nonparticipation in the context of Nation States and non-Statal Organizations before offering a brief survey of the terms Global Citizenship (GC), Digital Citizenship (DC), and GDC. Nonparticipation in an online context is then explained, followed by a discussion of practical concerns, such as who might enforce GDC rights among global digital citizens.
Transparency for institutions, privacy for individuals: the globalized citizen and power relations in a postmodern democracy
Authors: Zanon Breilla
Published: July 2020

The aim of this article is to observe how technologies of communication, especially the Internet - allow extensive and intensive connections between several global territories and how they begin to influence the formation of demands and the organization and participation of individuals/citizens around local and global causes. For this, the below article uses Wikileaks and the cypherpunk philosophy to exemplify how information can be both used and abused in the common space of the internet, allowing new citizenship developments as well as government control strategies.
Reverse mediations: digital methods of social research for digital citizenship
Authors: Pantoja Boechat Marina , De Carvalho Pereira Débora
Published: July 2020

Our society is heavily mediated by information technologies, so the simplest interactions become traceable, which collaborates to a deluge of data. They represent an abundant source for social analysis and an unparalleled opportunity for citizens to access, produce and disseminate information. Nevertheless, all this affluence of data, for presenting itself in a scattered way, also poses significant difficulties for achieving an integrated view of social reality and its interactions, and is organized in many competing interfaces and information architectures, that may produce, reinforce and disseminate ideologies, hegemonic discourse and platform biases. We identify an emerging field of dispute of the place of mediation of the many flows of information, and efforts for repurposing and restructuring these flows over the seamless structuring of different competing architectures. In order to describe some of these efforts, we draw examples from the field of controversy mapping, and propose the concept of reverse mediation.
A Marxist Account of and Suggested Alternative to Capitalist Academic Publishing
Authors: Peekhaus Wilhelm
Published: July 2020

This paper examines and situates theoretically from a Marxist political economic perspective the capitalist model of academic publishing using Marx’s concepts of ‘primitive accumulation’ and ‘alienation.’ Primitive accumulation, understood as a continuing historical process necessary for capital accumulation, offers a theoretical framework to make sense of contemporary erosions of the knowledge commons that result from various enclosing strategies employed by capitalist academic journal publishers. As a theoretical complement, the article further suggests that some of the elements of alienation Marx articulated in respect of capitalist-controlled production processes capture the estrangement experienced by the actual producers of academic publications. After offering a short assessment of the open-access movement as a remedial response to the enclosing and alienating effects inherent in the capitalist-controlled academic publishing industry, the article briefly outlines a suggested alternative model for academic publishing that, building on open-access projects, could radically subvert capitalist control.
Polarization of information and knowledge: a dialectical approach
Authors: Moreno Marques Rodrigo
Published: July 2020

This article discusses the polarization of information and knowledge, a phenomenon that is increasingly relevant in different spheres of the contemporary socioeconomic dynamics. According to this notion, founded mainly on the works of Karl Marx, information and knowledge are central elements in the contradictions between capital and labour, as well as in the internal contradictions of the working class. The idea of polarization of information and knowledge offers a critical point of view against the authors who, while trying to grasp the socioeconomic dynamics of our times, are captured by the enchantment of the techno-scientific progress. The article also adopts the Marxian concepts of universal labour and general intellect to argue that information, knowledge, and science are social constructions built collectively and should be treated as common goods. However, currently, the emancipatory perspective of the general intellect envisioned by Marx has been replaced by an opposite tendency: the private appropriation of the general intellect.
Information ethics and information literacy: A material-historical study between capital and class struggle in the Marxian perspective
Authors: Viola Carla
Published: July 2020

The present article analyzes ethics in Karl Marx perspectives, going through information ethics and information literacy that permeate individuation and class struggle in capitalist society. The objective is to approach critical reflection about dominated and dominant class’s ethics values proclaimed by author. In order to provide the desired research, I did literature review and digital documents consultation about the themes. Through this work, it is possible to identify that the author’s description of reality through historical materialism sought the dissemination of ethics through the ascertainment that individuals generate their stories, but these are not linked to their wills but directly linked to class formation and struggle as factors determining the circumstances under which the reality of society is constituted. It implies the search for mastery of language codes and information literacy to know, seize and disseminate information ethics aiming at the effective strategies elaboration to combat the ruling class hegemony.
In A Different Code: Artificial Intelligence and The Ethics of Care
Authors: Cohn Jonathan
Published: July 2020

The following essay explores the intersection of care with ethical reflections on artificial intelligence (AI). The current debate around AI ethics focuses on questions of moral AI judgment and the general criteria for maximizing the fairness, accountability, and transparency of these judgments. While this discussion is important, it all too often obfuscates the actual purpose and intention behind the use of the algorithmic or AI technology. Where the rationale for developing these technologies focuses on increasing optimization and innovation, concern must be shifted to ensure that AI will be used primarily to address current inequities and harms, from exacerbating climate change to manipulating voters via social media to creating “better” weapons.
Crossing Boundaries: Understanding Complex Scribal Practices in Ancient Egypt (with a 2019 Progress Report)
Authors: Polis Stéphane , Gabler Kathrin , Müller Matthias , Sojic Nathalie , Töpfer Susanne , Unter Stephan , Greco Christian , Loprieno Antonio , Hertel Elena , Pietri Renaud
Published: July 2020

In this paper, we introduce the joint project of the Museo Egizio (Turin), the University of Basel, and the University of Liège entitled “Crossing Boundaries: Understanding Complex Scribal Practices in Ancient Egypt”, and provide a progress report for 2019. The project deals with Ramesside hieratic papyri of the Turin collection that stem from Deir el-Medina (c. 1350–1050 BCE), adopting a contextualised approach to this written material. Crossing the boundaries between disciplines, we aim to shed light on the life of a particular category of complex documents, labelled “heterogeneous” papyri, i.e., papyri combining on a single support texts (or drawings) belonging to different genres.

Authors: Khalil Luma W.
Published: July 2020

This study was designed to investigate the effect of dill (Anethum graveolens) seeds in mitigating the complications of induced diabetes mellitus such as nephropathy of adult female rabbits. Thirty adult female rabbits were randomly assigned to 5 equal groups and treated daily for 45 days as follows: Control group (C) drenched tap water, control group intubated orally with 700 mg/kg B.W ethanolic extract of dill (T1), diabetic group drenched tap water (T2), diabetic group intubated orally700 mg/kg B.W of dill (T3) and diabetic group treated with insulin injection 3 I.U S/C (T4). Blood samples were collected by heart puncture at 0 and 45 days of experiment to assess renal efficiency: Serum creatinine, serum urea, and serum glutathione (GSH). The results indicated that diabetes mellitus without treatment group (T2) caused renal damage manifested by significant (P<0.05) increase in creatinine, urea and significant (P<0.05) decrease in serum glutathione (GSH) concentration. Oral intubation of alcoholic extract of dill seeds in diabetic treated group (T3) improved renal function through significant (P<0.05) decrease in serum urea, creatinine, and significant (P<0.05) increase in serum glutathione concentration (GSH). It was concluded that alcoholic extract of dill seeds was effective in reducing the complications of diabetes mellitus such as nephropathy.
