Authors: Wattan Saif Abdul Ameer , Al-Bakri Maythm 
Published: July 2019

A Geographic Information System (GIS) is a computerized database management system for accumulating, storage, retrieval, analysis, and display spatial data. In general, GIS contains two broad categories of information, geo-referenced spatial data and attribute data. Geo-referenced spatial data define objects that have an orientation and relationship in two or three-dimensional space, while attribute data is qualitative data that can be counted for recording and analysis. The main aim of this research is to reveal the role of GIS technology in the enhancement of bridge maintenance management system components such as the output results, and make it more interpretable through dynamic colour coding and more sophisticated visualization techniques than the conventional tabular data format.
To achieve the main objective of this research, two study areas have been chosen: the old construction bridge (Al-Qadisiyah bridge) and the newly constructed bridge (Barboty bridge). Both of them are in Al-Muthanna city \ Iraq. The data collection process was achieved in two stages: the first stage is providing a georeferenced satellite image for each study area for the purpose of producing a two-dimensional map. The second stage includes the field surveying process by total station and level instruments. GIS have been used to create a comprehensive database (Geodatabase) for both study areas. Geostatistical analysis was carried out in which the settlement areas of both study areas were defined by producing a colour image. The statistical tables for these analyses showed that the highest decline in the elevation reached at Al-Qadisiyah bridge to 19 mm in the middle of the bridge which is coloured as a red area. On the other hand, it was found that the highest decline in the elevation of the Barboty bridge is 16 mm in the last part of steel space which is also coloured as a red area.

A plastic tubes used as absorber of active flat plate solar collector (FPSC) for heating water were studied numerically and experimentally. The set-up is located in Babylon (republic of Iraq) 43.80 East longitude and 32.30 North latitude with titled of 450 toward the south direction. The study involved three dimensions mathematical model for flat coil plastic absorber which solved by FLUENT-ANSYS-R.18 program. Experiments were conducted at outdoor conditions for clear days on January and February 2018 with various water volume flow rates namely (500, 750, 1000, 1250, and 1500 Liter per hour LPH) on each month for Reynolds number range of (1 x 104 to 5 x 104) through the receiver. The experimental results showed improvement in absorber input - output temperature difference, collector efficiency, and water storage temperature; the maximum input - output temperature difference is 3.1 °C, the maximum collector efficiency is 79%, and the maximum water storage temperature is 67 °C. The comparison validates a good agreement between the numerical and experimental results at variable operation conditions with maximum deviation of 4.2%. Also the experimental results were compared with previous study for similar condition and gave a good improvement.
The Characters of the Form in the Vernacular Architecture A comparative study of the form's characters of facades of individual houses and commercial buildings in the City of Baghdad after 2003–Zayoona district as a case study
Authors: Salih Amna Bassim Mohamed 
Published: July 2019

The characters of facades' form of the Iraqi building after 2003 have been changed, it has been described by many names. The problem of the research is that what are the features of the characters of the form in the façades of the buildings in Baghdad city after 2003? Are the façade of the individual houses or the commercial buildings is the heaviest in the visual weight? The research aims to answer those questions by choosing the vernacular architecture as a measurement tool. It is the informal image of the architecture, which is built by people informally and spontaneously, without official control and legislation to be organized. This is smellier to what has happened in Baghdad, after 2003 according to previous study submitted by the same researcher (The phenomenon of trespassing the architectural design regulation in the Iraqi cities 2003-2016- case study Baghdad) the individual houses as a case study. The research method has dealt with the previous studies, and with the terms and the vernacular architecture in some Arabic countries. The research determines the features of the form's characters in the façades of the vernacular architecture in Egypt, Yemen, and Palestine as the generic features of the vernacular taste in Arabic societies. The researcher examines these features by checking list and Excel program and by selecting samples in Zayoona district after 2003 as a case study. The research's hypothesis has proved that the form's characters of local façades in Baghdad after 2003 are a rural vernacular. The facades of the individual houses have had the heaviest influences at the visual weight. The research has concluded that the characters of the vernacular architecture's form have common and basic styles among societies. when it has manifested in cities, showed their architectural style and identity, it indicates a decline in both architectural style and identity. The heavy influences of the visual weight in Iraqi architecture after 2003 depends on the decoration included two types: the rhythmic and geometric decoration, being important elements in the facades.

Jaringan Pesantren di Jawa Barat Tahun 1800-1945: Critical Review atas Disertasi “Jaringan Pesantren di Priangan 1800-1945” Karya Ading Kusdiana
Authors: Fauzan Pepen Irpan , Fata Ahmad Khoirul 
Published: July 2019

Pesantren as subcultures are indeed interesting to be studied. Several studies have been carried out such as Zamakhsary Dhofier on the network of pesantren in Java and Martin van Bruinessen on the pesantren and tarekat. Continuing it, Ading Kusdiana through her dissertation at Padjadjaran University conducted a research on the network of Pesantren in the Priangan region (West Java), focusing on the existence and conti­nuity of Pesantren through five inter-Islamic networks: scientific networks, marriage, genealogical, congregational religious views, and the similarity of the vision of opposition to the invaders. Kusdiana's research confirmed Zamakhshari Dhofier's theory and did not refute it at all. So that this feels like a new work with a sense of "old work". The study of this theme will be even more interesting if Kusdiana uses the new genealogical theory as Yudi Latif did. This will also portray changes and continuity in the network of Pesantren. However, Kusdiana’s work deserves to be appre­ciated because it presents a lot of new data-information regarding the traces and spreads of Pesantren in Priangan. Through thiswork, we can get a relatively completed picture of the world of Pesantren in Priangan in the 1800-1945 period.Keywords: Network of Pesantren, Genealogy Theory, Pesantren in Priangan Pesantren sebagai subkultur memang menarik dikaji. Beberapa kajian telah dilakukan seperti Zamakhsary Dhofier tentang jaringan pesantren di Jawa dan Martin van Bruinessen tentang pesantren dan tarekat. Melanjut­kan keduanya, Ading Kusdiana melalui disertasinya di Universitas Padjadjaran melakukan penelitian jaringan pesantren di wilayah Priangan (Jawa Barat), dengan titik-fokus pada proses eksistensi dan kesinam­bungan pesantren melalui lima bentuk jaringan antarpesantren: jaringan keilmuan, perkawinan, genealogis, kesamaan pandangan keagamaan tare­kat, serta kesamaan visi penentangan terhadap penjajah. Namun penelitian Kusdiana ini meneguhkan teori Zamakhsyari Dhofier dan sama sekali tidak melakukan penyanggahan terhadapnya. Sehingga ini terasa sebagai karya baru dengan rasa “karya lama”. Kajian terhadap tema ini akan semakin menarik jika Kusdiana menggunakan teori genealogis baru seperti yang dilakukan Yudi Latif. Ini sekaligus akan memotret perubahan dan kontinuitas dalam jaringan pesantren yang dikajinya. Namun demikian, karya Kusdiana ini layak diapresiasi karena menyajikan banyak data-informasi baru terkait jejak dan sebaran-pertumbuhan pesantren di Priangan. Melalui karya Kusdiana ini, kita bisa mendapatkan gambaran relatif utuh terkait dunia pesantren di Priangan pada periode 1800-1945.Kata Kunci: Jaringan Pesantren, Teori Genealogi, Pesantren di Priangan

Published: July 2019

A relativistic, static and spherically symmetrical stellar model is presented, constituted by a perfect charged fluid. This represents a generalization to the case of a perfect neutral fluid, whose construction is made through the solution to the Einstein-Maxwell equations proposing a form of gravitational potential $g_{tt}$ and the electric field. The choice of electric field implies that this model supports values of compactness$u=GM/c^2R\leq 0.5337972212$, values higher than the case without electric charge ($u\leq 0.3581350065$), being this feature of relevance to get to represent compact stars. In addition, density and pressure are positive functions, bounded and decreasing monotones, the electric field is a monotonously increasing function as well as satisfying the condition of causality so the model is physically acceptable. In a complementary way, the internal behavior of the hydrostatic functions and their values are obtained taking as a data the corresponding to a star of $1 M_\odot$,for different values of the charge parameter, obtaining an interval for the central density $\rho_c\approx (7.9545,2.7279) 10^{19}$ $ Kg/m^3$ characteristic of compact stars.
Motion of a rolling sphere on an azimuthally symmetric surface
Authors: Marín Quiroz D. M. 
Published: July 2019

This paper analyzes the translational motion that a sphere rolling over an azimuthally symmetric surface, under the presence of a constant gravitational field, and with the rolling-without-slipping condition, exhibits in two different situations: with and without friction with air, where the latter is expressed as a power-series function of the sphere’s translational speed. In order to achieve this, the equations of motion for each case are obtained through the use of Lagrangian Mechanics and are subsequently solved by numerical computation in Wolfram Mathematica. For the frictionless case, periodic behavior and a conservation law for the angular coordinate have been found, along with the condition under which an effective potential energy can be approximated as well as the relationships between initial conditions that produce gravitational-like trajectories for the motion of the sphere. The equations of motion derived for the case with friction are found to predict the energy loss and general decay of the sphere’s motion. Likewise, the normal force over the sphere as a function of time is obtained through the method of Lagrange's Undetermined Multipliers, and thus, the general conditions that the motion must satisfy in order to be described by the obtained models. Overall, this research provides insight into the type and characteristics of the motion performed by the system in these two cases, both through equations and their numerical solutions for different surfaces and initial conditions.

Discriminatory Customary Practices Against Women’s Rights: An Account Of Intervention Strategies By Southern African Developing States
Authors: Raji Barakat Adebisi , Akolokwu Grace Ogonda 
Published: July 2019

Discriminatory customary practices against the protection of gender rights still thrive in many Southern African developing states despite domestic and international legal regimes to prevent them. These practices were borne out of customary inclinations of the patriarchal social system in most African communities, which hold women and the girl-child in perpetual subordination to the male. In other words, the African customary systems wrongly perceive the male gender as being naturally superior to the female. More so, the loopholes in the executive and legislative efforts to combat human rights abuses as well as judicial pronouncements and governmental apathy in eradicating abuses against gender discrimination towards women in the Southern African developing states are apparent. Consequently, discriminatory customary practices continue to thrive despite legislative framework protecting gender rights in the states. The methodology adopted in this paper is a doctrinal approach, which places reliance on legal materials that are enacted and enforced by African Developing states. The article examines international and states laws, norms, institutions, international and national publications and other international legal instruments relating to gender discrimination. Most importantly, the central attention of this study focuses on the discriminatory customary practices against women in the Southern African Developing States. The current study finds that, despite identifiable discriminatory customary practices which are still practised and condoned as being the lifestyle and tradition of groups are criminalized and declared abhorrent by specific domestic legislation of nations, the human rights of the girl-child and women continue to be in chains and fetters. In conclusion, this article advocates increased advocacy, judicial activism and more proactive legislative action that protect women and the girl-child in the Southern African developing states.

It was written in memory the author’s son Muhammad Zayd bin Bohorudin (1985-2017), advocate and solicitor, and alumnus of the Ahmad Ibrahim Kulliyyah of Laws (‘AIKOL)’. It is a continuation of Part I, published in the IIUM Law Journal Vol. 26 (2) 2018.
In this part, the issue of constitutionality of the developer using the purchaser’s property to secure loan is discussed. It furthermore examines the defects and weaknesses in the operation of several clauses in the Act to the purchaser. Other key issues discussed are the criticism on the house purchase loans, the purchase price and other expenses, the post-execution position of the purchaser as beneficial owner, construction issues, and the developer’s first duty, namely to give clean title to purchaser. At a later part of the article, the position of purchasers in relation to the abandonment of the housing estate, foreclosure, private sale and other disasters are scrutinised. Purchasers’ rights pertaining to the completion of the construction, transfer and registration of the house, as well as their right to life vis-à-vis housing matters are assessed.
