Geochemistry and Determination of Mineral Properties of Dolomite Deposit in Ikpeshi Southern, Nigeria

This work focused on the geochemistry and determination of the mineral properties’ distribution of dolomite deposit from Ikpeshi, using variogram analysis, Samples collected from the study area were subjected to laboratory analysis to determine the porosity, water content and geochemical properties. Variograms maps were constructed and fitted to the model. The results of the variogram analysis were used in plotting of predictive maps which show the property distribution of the dolomite. The porosity varies between 0.68%–3.24% and the Water Content varies between 0.1–1.65%. The geochemical analyses reveal that the average concentration of the elemental oxides is 1.790, 0.461, 0.299, 0.045, 20.380 and 46.130 for SiO2, Al2O3, Fe2O3, MnO, MgO and CaO, respectively. CaO and MgO are more abundant when compared with other major elements; the predictive maps of the distribution and directions of the mineral properties and the distribution are not uniform in all directions which indicates that the mineral properties of the dolomite deposit are anisotropic.

Simulation of Single Channel Magnetic Induction Tomography for Meningitis Detection By Using COMSOL Multiphysics

Meningitis is a inflammation of the meninges and the most common central nervous system (CNS) due to bacterial infection. Numbers of children who have bacterial meningitis are still high in recent 15 years regardless of the availability of newer antibiotics and preventive strategies. This research focuses on simulation using COMSOL Multiphysics on the design and development of magnetic induction tomography (MIT) system that emphasizes on a single channel rotatable of brain tissue imaging. The purpose of this simulation is to test the capability of the developed MIT system in detecting the change in conductivity and to identify the suitable transmitter-receiver pair and the optimum frequency based on phase shift measurement technique for detecting the conductivity property distribution of brain tissues. The obtained result verified that the performance of the square coil with 12 number of turns (5Tx-12Rx) with 10MHz frequency has been identified as the suitable transmitter-receiver pair and the optimum frequency for detecting the conductivity property distribution of brain tissues.

Lp-Norm Inversion of Gravity Data Using Adaptive Differential Evolution

As a popular population based heuristic evolutionary algorithm, differential evolution (DE) has been widely applied in various science and engineering problems. Similar to other global nonlinear algorithms, such as genetic algorithm, simulated annealing, particle swarm optimization, etc., the DE algorithm is mostly applied to resolve the parametric inverse problem, but has few applications in physical property inversion. According to our knowledge, this is the first time DE has been applied in obtaining the physical property distribution of gravity data due to causative sources embedded in the subsurface. In this work, the search direction of DE is guided by better vectors, enhancing the exploration efficiency of the mutation strategy. Besides, to reduce the over-stochastic of the DE algorithm, the perturbation directions in mutation operations are smoothed by using a weighted moving average smoothing technique, and the Lp-norm regularization term is implemented to sharpen the boundary of density distribution. Meanwhile, in the search process of DE, the effect of Lp-norm regularization term is controlled in an adaptive manner, which can always have an impact on the data misfit function. In the synthetic anomaly case, both noise-free and noisy data sets are considered. For the field case, gravity anomalies originating from the Shihe iron ore deposit in China were inverted and interpreted. The reconstructed density distribution is in good agreement with the one obtained by drill-hole information. Based on the tests in the present study, one can conclude that the Lp-norm inversion using DE is a useful tool for physical property distribution using gravity anomalies.

Joint Property Distribution upon Divorce Reviewed From the Contribution of Husband and Wife in the Household

Joint property distribution has been regulated in the Islamic Law Compilation (KHI), namely, Article 97 which explains that a widow or widower is entitled to half of the joint property. The distribution is fair if the husband and wife make the same contribution in the marriage. However, in fact, today we often find that wives are being the backbone of the family while husbands do not earn a living or husbands earn a living for the family, but wives do not take care of the household. If such a situation is found, is the article 97 of KHI still relevant? This paper presents a concept of joint property distribution based on the contribution of husband and wife in marriage which is considered fairer for both of them than what has been stipulated in the KHI and the Civil Code Articles 128-129. The type of research used is descriptive research. This means that research is discussed in the form of an explanation described in words carefully and thoroughly. The approach method used in this research is a normative juridical approach. The results of this study explain that to obtain the justice, judges can act contra legem (against the law) where justice should give a share to everyone based on his services or contributions (Aristotle). The joint property distribution in marriage from a justice perspective is the distribution of joint property by assessing the amount of contribution of the parties. A fair share does not have to be 50% for widowers and 50% for widows. The husband can get a smaller share from the wife if the contribution is less during the marriage and does not carry out his obligation as the breadwinner and the wife can get a larger share from the husband if the wife plays a dual role, and vice versa.Pembagian harta bersama telah diatur dalam Kompilasi Hukum Islam yakni pada pasal 97 dijelaskan bahwa janda atau duda berhak separuh dari harta bersama. Pembagian tersebut adil apabila suami dan istri memberikan kontribusi yang sama dalam perkawinan. Akan tetapi pada faktanya saat ini sering kita temui istri menjadi tulang punggung keluarga sedangkan suami tidak mencari nafkah atau suami mencari nafkah untuk keluarga akan tetapi istri tidak mengurus rumah tangga. Jika ditemukan keadaan seperti itu apakah masih relevan KHI pasal 97 tersebut. Tulisan ini menyajikan sebuah konsep pembagian harta bersama berdasarkan kontribusi suami istri dalam perkawinan yang dinilai lebih adil untuk keduanya daripada apa yang sudah diatur dalam KHI dan KUHPerdata Pasal 128-129. Hasil dari penelitian ini dijelaskan bahwa untuk mendapatkan sebuah keadilan hakim dapat bertindak contra legem (mengenyampingkan undang-undang) dimana keadilan itu seharusnya memberikan bagian kepada setiap orang didasarkan atas jasa-jasanya atau kontribusinya (aristoteles). Pembagian harta bersama dalam perkawinan jika dilihat dari perspektif keadilan adalah pembagian harta bersama dengan menilai besaran konstribusi para pihak. Dimana pembagian yang adil tidak harus 50 % untuk duda dan 50% untuk janda. suami bisa mendapatkan bagian yang lebih kecil dari istri apabila kontribusinya kurang selama perkawinan dan tidak menjalankan kewaibannya sebagai pencari nafkah dan istri bisa mendapatkan bagian yang lebih besar dari suami jika istri berperan ganda, begitu uga sebaliknya.

A Traceable Online Will System Based on Blockchain and Smart Contract Technology

In recent years, with the rapid levels of economic development, there have been more and more problems in property inheritance and distribution. In today’s society, people still have many taboos when writing a will. Writing a will not only involves various laws and regulations but also costs a lot of money and time, which can be daunting. However, with the development of the Internet, blockchain technology has gradually been applied to many applications. Blockchain technology uses consensus algorithms to ensure consistency and records transaction information in blocks to ensure the effectiveness of transactions. In this paper, we use the cryptography mechanism to propose an online will system based on blockchain and smart contract technology. The architecture considers effectiveness and cost reduction. By combining this with blockchain technology, will assets are saved in blocks, which provides comprehensive will security and non-tamperable security protection. In addition, combined with a smart contract, it realizes the method of automatic property distribution. At the same time, this mechanism also proposes an arbitration solution when there are disputes over wills, and ensures the integrity of data, public verifiability, unforgeability, nonrepudiation, irreversibility of information, and the ability to resist counterfeiting attacks.

The Renaissance of Roman Colonization

The colonization policies of Ancient Rome followed a range of legal arrangements concerning property distribution and state formation, documented in fragmented textual and epigraphic sources. Once antiquarian scholars rediscovered and scrutinized these sources in the Renaissance, their analysis of the Roman colonial model formed the intellectual background for modern visions of empire. What does it mean to exercise power at and over distance? This book foregrounds the pioneering contribution to this debate of the great Italian Renaissance scholar Carlo Sigonio (1522/3–84). His comprehensive legal interpretation of Roman society and Roman colonization, which for more than two centuries remained the leading account of Roman history, has been of immense (but long disregarded) significance for the modern understanding of Roman colonial practices and of the legal organization and implications of empire. Bringing together experts on Roman history, the history of classical scholarship, and the history of international law, this book analyses the context, making, and impact of Sigonio’s reconstruction of the Roman colonial model. It shows how his legal interpretation of Roman colonization originated and how it informed the development of legal colonial discourse, from visions of imperial reform and colonial independence in the nascent United States of America, to Enlightenment accounts of property distribution, culminating in a specific juridical strand in twentieth-century Roman historiography. Through a detailed analysis of scholarly and political visions of Roman colonization from the Renaissance until today, this book shows the enduring relevance of legal interpretations of the Roman colonial model for modern experiences of empire.

The Model of Implementation 0f Property Distribution After Divorce of Local Wisdom Perspective in Madura

This study's purpose is to reveal and determine the implementation model of the distribution of marital property after divorce from the perspective of Madurese local wisdom. This research uses the empirical juridical method; according to Ronny Hanitijo Soemitro, a law that is empirically a symptom of society, on the other hand, can be studied as a variable (independent variable) which causes consequences on various aspects of social life. In social studies, the law is not conceptualized as an independent (autonomous) normative phenomenon, but as social institutions which are associated in real terms with other social variables. The results of this study are: a model for the implementation of post-divorce marital property distribution in the perspective of Madurese local wisdom, with the wisdom of distributing marital assets after divorce by distributing them into several models or forms as follows: (1) following the distribution model according to the positive legal arrangement of Indonesia, namely what is regulated in state law and is decided by the Religious Court, that the distribution of marital assets, namely widows or divorced widowers, each has the right to a half of the marital assets as long as it is not stipulated otherwise in other agreements in marriage. Meanwhile, based on the Article 37 of Law Number 1 the Year 1974 concerning the marriage, if the marriage breaks up due to divorce, marital assets is regulated according to their respective laws. Meanwhile, according to the Civil Code (KUH Perdita), Article 128, after the dissolution of marital assets, their marital assets are divided between husband and wife, or between their heirs, without question of which party the goods originated from. (2) the post-divorce model of the distribution of marital assets in the perspective of Madurese local wisdom is based on the wisdom of each individual soul or soul of a divorced husband and wife. The wisdom of each of these minds or souls is partly rooted in the Madurese community, which in this paper is called wisdom. As part of local wisdom in Madura, the distribution of marital assets is carried out by means of mediation (abeq remember) attended by community leaders.
