Postfazione. Utopia e speranza: Bologna per Patrick Zaki
No full textThe essay elaborates on the talk the author delivered during the ceremony that took place after the liberation from prison of the UNIBO and honorary citizen of Bologna, Patrick Zaki. The essay elaborates on the following issues: the support of the university and city, the value of human rights, academic freedom, and public squares as spaces of democracy. It includes a longer part on utopia (as a literary genre and a political instrument of change) and hope, quoting academic scholars (Karl Mannheim, Ernst Bloch, Ursula Le Guin, Antonio Gramsci, Howard Zinn) and it explains the function of hope in utopia

No full textImprovement of the Richardson-Zaki liquid-solid fluidisation model on the basis of hydraulics
No full textOne of the most popular and frequently used models for describing homogeneous liquid-solid fluidised suspensions is the model developed by Richardson & Zaki in 1954. The superficial fluid velocity and terminal settling velocity together with an index makes it possible to determine the fluid porosity in a straightforward way. The reference point for the Richardson-Zaki model is the terminal settling velocity at maximum porosity conditions. To be able to predict porosity in the proximity of minimum fluidisation conditions, either the minimum fluidisation velocity must be known or the Richardson-Zaki index must be very accurate. To maintain optimal process and control conditions in multiphase drinking water treatment processes, the porosity is kept relatively low. Unfortunately, the Richardson-Zaki index models tends to overestimate the minimum fluidisation velocity and therefore also results in less accurate predictions with respect to porosity values. We extended the Richardson-Zaki model with proven hydraulics-based models. The minimum fluidisation velocity is acquired using the model proposed by Kozeny (1927), Ergun (1952) and Carman (1937). The terminal settling velocity is obtained through the model developed by Brown & Lawler (2003), which is an improved version of the well-known model developed by Schiller & Naumann (1933). The proposed models are compared with data from expansion experiments with calcium carbonate grains, crushed calcite and garnet grains applied in drinking water softening using the fluidised bed process. With respect to porosity, prediction accuracy is improved, with the average relative error decreasing from 15% to 3% when the classic Richardson-Zaki model is extended with these hydraulics-based models. With respect to minimum fluidisation velocity, the average relative error decreases from 100% to 12%. In addition, simplified analytical equations are given for a straightforward estimation of the index n.Complex Fluid ProcessingSanitary Engineerin

Time Structure in the Novella "Exiting Marj bin Amer" by Zaki Darwish
No full textتجدر الإشارة إلى أنّ الزّمن القصصيّ أهمّ عناصر الحبكة القصصيّة التي تتشكّل من: الزمان، المكان، الشخصيّات، الأحداث، والرّاوي. هذه العناصر تتعالق وتتداخل في كلّ عمل قصصيّ مشكّلة حبكته.
سنقوم بدراسة بناء الزّمن في رواية الخروج من مرج ابن عامر[1] من وجهين:[2] الترتيب الزمنيّ، والمدة أو السرعة، كي نستطيع الوقوف على خصائص البناء الزمنيّ: هل هو بناء تقليديّ أم حداثيّ؟ وعلاقة هذا البناء بدلالات القصّة، لأنّنا نؤمن بوجود علاقة جدليّة بين بناء العمل الفنيّ ودلالته، بمعنًى آخر كيف يخدم البناء والتقنيّات الفنيّة دلالات القصّة؟
ومن أجل تسهيل الدّراسة سنقوم بتفكيك هذه العناصر، مؤكّدين على أنَّ هناك علاقة بين التقنيّات المستعملة ودلالات القصّة.This study examines the structure of time in Zaki Darwish’s novella "Exiting Marj bin Amer". The novel is examined through two lenses, chronological order and temporal rhythm, in an attempt to answer the question: Is the structure of time in the novella traditional or modern? By ‘traditional’, we mean that the actions and events in the story are ordered chronologically, as if they have happened in real life.
The study argues that broken time structure in this novel underscores the protracted suffering of the Palestinian people as they refuse to be uprooted from their land. More specifically, it shows that the writer uses a variety of devices -- descriptions and comments, flashbacks and monologues – that slow, halt and distort the progress of events to reflect the anguish of the Palestinians in their dogged rejection of their situation
Analysis of importance value index of unlogged and logged peat swamp forest in Nenasi Forest Reserve, Peninsular Malaysia
No full textIsmail MH, Fuad MFA, Zaki PH, Jemali NJN. 2017. Analysis of importance value index of unlogged and logged peat swamp forest in Nenasi Forest Reserve, Peninsular Malaysia. Bonorowo Wetlands 1: 74-78. Peat swamp forests are highly significant globally, both for their diverse and threatened species and as a representative of unique wetland ecosystems. Apart from its critical role in providing habitat for wildlife, the tropical peat swamp forest also acts as a gene bank that harbors potentially useful varieties of plant species. The composition of trees of the peat swamp forest in Nenasi Pahang State, Peninsular Malaysia were investigated especially in un-logged and logged over forests. The objectives of this study are two folds; (i) to identify and compare the dominant tree species in the two types of forests and (ii) to calculate the importance value index (IVI) of the vegetation in the study areas. Two plots of 50 m by 20 m were established in different forest type. At each site this quadrate was in turned subdivided using a 25 m by 20 m, and 5 m by 5 m, respectively. The results showed that the unlogged peat swamp forest is higher in tree species compared to logged peat swamp forest. There were 10 species distributed among 9 families in the unlogged forest and 7 species in 7 families in the logged forest. The most dominant species identified in unlogged peat swamp forest were Litsea sp., Syzygium sp. and Santiria laevigata. The IVI for these species were 71.21, 51.13 and 42.49. In logged peat swamp forest the dominant species are Shorea platycarpa, followed by Pometia pinnata, and Xylopia fusca. The IVI of these species were 87.38, 52.66 and 47.55, respectively. The study concludes that in the logged peat swamp forests about 40 percent of the tree composition has declined compared to unlogged peat swamp forest.</jats:p

No full textThis paper discusses the impact of Short Messaging Services (SMS) in the information age. It starts with the coming of information age and the need to access to vital information when people are mobile. In the information age, we are being bombarded with lots of information and we have to manage it in the most efficient way. How does one filter all these information? One way the author sees in doing it is via Short Messaging Services (SMS). Users need a tool that they carry around and this tool can help them in accessing information as and when they want it. The tool that the author is going to elaborate is the mobile phone and the bearer that the tool utilizes is Short Messaging
