The Concept of Property and Ownership in Islam

The aim of this research is to know how the concept of property ownership in Islamic economics according to Afzalur Rahman, to know how to implement the concept of property ownership in Islamic economics by Afzalur Rahman at this time and to know how Afzalur Rahman's thought analysis of concepts ownership of property in Islamic economics. The research method that writer use is library research (library research) where the data and data sources are obtained from a review of the literature according to the problem. The result showed that the opinion expressed by Afzalur Rahman on the concept of ownership in the Islamic economic system is in harmony with the economic principles that require the system an economy compatible with the Qur'an and Sunnah. Where Islam also wants every person in possession of good property in the form of goods or services obtained in a way halal both the form of substance and how to get it, not destroy and destroy human nature, nor do the persecution and exploitation, the purpose ultimately is to fight for the needs of human life and seek pleasure Hereafter is blessed by Allah SWT.

A Rehabilitation of the Law of Diminishing Marginal Utility: An Ordinal Marginal Utility Approach

The model in which an individual maximizes his ordinal or cardinal total utility has long been the paradigm of individual choice theory. However, the two mainstream utility theories, the ordinal and cardinal total utility theories, have caused a dilemma, i.e. one has to sacrifice one of the following two: the good property of utility ordinality, or common-sense notions such as the law of diminishing marginal utility. Ordinal theory keeps the former but gives up the latter, while cardinal theory keeps the latter but sacrifices the former. We propose an ordinal marginal utility approach aiming to solve this dilemma by changing the very first assumption regarding individual choice.

Hydrothermal synthesis, characterization and gas sensing of Bi2MoxW1−xO6

Bi2MoxW[Formula: see text]O6 microspheres are synthesized by simple one-step hydrothermal method and the morphological characterizations are performed by X-ray diffractometer (XRD), X-ray photoelectron spectroscopy (XPS), BET, scanning electron microscopy (SEM), transmission electron microscopy (TEM). The gas sensing of Bi2WO6, Bi2MoO6 and Bi2MoxW[Formula: see text]O6 is investigated. It can be concluded that the sensor of Bi2MoxW[Formula: see text]O6 has the same good sensitivity as pure Bi2MoO6 and Bi2WO6 to alcohol. It is noteworthy that the operating temperature of Bi2Mo[Formula: see text]W[Formula: see text]O6 is 200∘C which is lower than that of pure Bi2WO6 or Bi2MoO6 (240∘C), so Bi2MoxW[Formula: see text]O6 show its good property for alcohol gas sensing application.

Column-orthogonal strong orthogonal arrays of strength two plus and three minus

Summary Strong orthogonal arrays have better space-filling properties than ordinary orthogonal arrays for computer experiments. We consider column-orthogonal strong orthogonal arrays of strength two plus and three minus, and present methods of constructing such designs. Several situations are examined, including those of four or higher levels and mixed levels. The methods are based on both regular and nonregular designs. The resulting designs inherit the good property of strong orthogonal arrays of strength two plus or three and have the additional property of column orthogonality. This type of design is a better choice for computer experiments.

Exploring the Multi-Stage Effects of Material Preparation and Printing on 3D Printing Product Quality

3D printing is a promising technique to fabricate flexible parts and reduce the supply chain. Various materials, such as metal powders, plastics, ultraviolet (UV) sensitive resins, can be fabricated from 3D printing and form the final printed part. Currently, most researchers either focus on exploring printable materials with good property or focus on the process quality control given a certain type of material. However, for many 3D printing processes, the printing process and product properties are dependent on both the material properties and process settings. To the best of the authors’ knowledge, the quantitative analysis of the interactions of material properties and printing process settings are rarely studied. In this paper, we treat the material preparation and 3D printing as different manufacturing stages, and we explore the multi-stage effects in 3D printing. In particular, we add carbon fiber to the CLEAR resin to alter the material properties for a stereolithography (SLA) 3D printing process. It is observed that the part properties are jointly affected by material properties and printing process settings. Therefore, the material property and process settings should be jointly considered for optimizing 3D printing processes.

New Silicone-Resin-Compounds for Casting and Molding Applications

Silicone resins are manufactured and supply in various delivery forms since decades. The impregnation of large electrical machines demonstrates a main application in the field of electrical insulation technology at the moment. Silicone resins are characterized by outstanding resistance to heat stress at high temperatures in general. Experience has shown that they are also very stable against exposure to UV radiation. Based on the expected very good property profile, Wacker Chemie AG developed a solvent-free, low-viscosity silicone resin for use as a binder for castable and moldable products. The article presents the chemical composition of silicone resins, the resulting properties of the resin and selected results of the extensive work for the evaluation of possible fillers and filler mixtures as well as first experience with the processing.

Evaluation of Mechanical Properties of Kevlar Fibre Reinforced Aluminium 6061 Sandwich Composites

In the present scenario composite materials has got a good value in making a high strength component. Kevlar fibre reinforced composite have a good property of making materials with high strength and low weight. With proper fabrication these Kevlar fibres will produce good property in making components that will be used for specific applications. Our project is dealt with the preparation of a laminate using Kevlar fibre reinforced composite in 0o-90o orientation by using epoxy resin as adhesive and to analyze the mechanical properties of that particular laminate and study that it has high mechanical properties or not. Main objective of this project is to make a composite laminate with high strength, high stiffness, and low weight for various applications.

On 2-nil-good rings

A ring [Formula: see text] is defined to be 2-nil-good if every element in [Formula: see text] is the sum of two units and a nilpotent. Fundamental properties of such rings are obtained. We prove that every strongly [Formula: see text]-regular ring is 2-nil-good if and only if the identity is the sum of two units. One of the main result of this paper is that every square matrix ring over J-fine rings is 2-nil-good. We establish 2-nil-good property for Morita contexts. This implies, in particular, that every matrix ring over 2-nil-good rings is 2-nil-good. Furthermore, we prove that the ring [Formula: see text] of all lower triangular diagonal-finite matrices over a 2-good ring [Formula: see text] is 2-nil-good.
