Studying the Types, Bases and Features of Sale from the Perspective of Islamic Jurists

Sale is known as one of the most widely used words in Islamic jurisprudence. Islamic jurists have each defined the nature, bases and types of sale as one of the specific and important Islamic contracts. Regarding sale, it should be mentioned that in some definitions, the early Imami jurists considered its nature as the exchange of two properties, while the famous Islamic jurists consider its nature as the demand and acceptance, which makes the object of sale the property of the customer and regards the price as the property of the seller. Another point is that, in the definitions of late and contemporary Imami jurists, there is a kind of semantic alteration in the interpretation of sale. From the view point of Islamic jurists, it seems that the elements of possession and ownership in the sale are concepts with wide conceptual scopes, and this is the superiority and distinction of Imami jurists over other jurists regarding the truth of sale. On the other hand, from the point of view of Islamic jurists, there are different types of sale, the most important of which are strict sale, contractual sale, absent sale, harmful sale, credit sale, general sale, deferred sale, gifted (mohabati) sale, debt sale, Morabahe (a sale based on a fixed price), etc. On the other hand, the bases of sale from the perspective of Islamic jurists are: demand and acceptance, buyer and seller, property sold, and price in the sale contract. Also, the features of sale from the point of view of jurists are: the ownership of the sale, the exchange of the sale, the objectivity of the property, the necessity of the sale contract. The research methodology in this paper is descriptive-analytical using the library method

Burden of Proof and Presumption of Innocence in the Prosecution of Illicit Enrichment with Reference to the Jordanian Legislation

It is recognized that the burden of proof in criminal justice is on the shoulder of the prosecution. Likewise, the presumption of innocence is a fundamental principle of human rights concerning fair trials, rights of person to remain silent and principle of innocence until proven guilty beyond reasonable doubts. However, the burden of proof can be shifted from the prosecutor to the defendant in some cases like in cases of money laundering, tax evasion, smuggling, terrorism and illicit enrichment. Hence, this article argues that the right of accused must be balanced against the right of society. This article found that some scholars and in some jurisdictions reject the shifting of onus of proof to the defendant to protect the fundamental provisions of human rights. This article also argues that the burden of proof should be understood as an instrument to curb corruption and deprive corruptors from the proceeds of crimes rather than the exaggeration the presumption of innocence. Keywords: burden of proof; presumption of innocence; prosecution; illicit enrichment

Identificando os componentes da gestão de talentos na organização aduaneira do Irã pelo método delphi-fuzzy (estudo de caso)

Talent management is a system for identifying, upbringing, promoting, and preserving talented persons to optimize the capability of an organization to come up with optimal business results. Nowadays, the developing talent management is one of the most important business factors, which is considered as one of the key components to maintain a sustainable competitive advantage in organizations. the purpose of this study was to identify the components of talent management in the custom organization so that its implementation will be expedited.

An Investigation into Different Power Consumption Parameters of Rushton Turbines: A Computational Survey

In the present work, the mixing process of shear thinning liquids in a six-blade Rushton turbine is studied. A finite volume based computational fluid dynamics (CFD) simulation has been carried out and the three-dimensional turbulent flow is numerically analyzed by using the Shear Stress Transport k-ω (k-ω SST) model. Shear thinning liquids were investigated and shear thinning behaviour was modelled by the Ostwald-de Waele law. The used stirred vessel has a cylindrical shape with a flat bottom and the liquid height was kept equal to the vessel diameter. Effects of the power law index and the angle of attack of the blade on power consumption have been investigated. The results show that decreasing the angle of attack from 90° to 45° not only results in an increase in the flow rate down to the bottom of the vessel, resulting in a better mixture qualification, but also reduces the power consumption of the stirring process. To verify the simulation, axial, radial and tangential velocity components were compared with other experimental data and satisfactory agreement was found

Determining Induction Conditions for Expression of Truncated Diphtheria Toxin and Pseudomonas Exotoxin A in E. coli BL21

Background: Targeted cancer therapies have played a great role in the treatment of malignant tumors, in the recent years. Among these therapies, targeted toxin therapies such as immunotoxins, has improved the patient’s survival rate by minimizing the adverse effect on normal tissues, whereas delivering a high dose of tumoricidal agent for eradicating the cancer tissue. Immunological proteins such as antibodies are conjugated to plant toxins or bacterial toxins such as Diphtheria toxin (DT) and Pseudomonas exotoxin A (PE) . In this case optimizing and expressing Diphtheria toxin and Pseudomonas exotoxin A which their binding domains are eliminated play a crucial role in producing the desired immunotoxins.Materials and Methods: We expressed the truncated DT and PE toxin in a genetically modified E.coli strain BL21 (DE3). For this reason we eliminated the binding domain sequences of these toxins and expressed these proteins in an expression vector pET28a with the kanamycin resistant gene for selection. The optimization of Diphtheria toxin and Pseudomonas exotoxin A expression was due to different IPTG concentration, induction and sonication time. Results: We observed that the optimal protein expression of the Diphtheria toxin was gained in 4 hours of 0.4 mM IPTG concentration at 25˚C on the other hand the optimization of Pseudomonas exotoxin A protein occurred in 4 hours of 0.5 mM IPTG concentration at 25 ˚C.Conclusion: Our study also showed lower IPTG concentrations could result in higher protein expression. By optimizing this procedure, we facilitate the protein production which could lead to acceleration of the drug development

The Effect of Deproteinized Bovine Bone Mineral on Saos-2 Cell Proliferation

Introduction: Deproteinized bovine bone mineral (Bio-Oss) is a xenogenic bone substitute, widely used in maxillofacial bone regeneration. The aim of this in vitro study was to investigate its influence on the growth behavior of human osteosarcoma cell line, Saos-2 culture, and compare it with the physiologic dose of Dexamethasone, an inductive factor for osteoblasts. Materials and Methods: Human osteosarcoma cells, Saos-2, were cultured on Bio-Oss and their growth rate was compared to Saos-2 cultures treated with Dexamethasone 10-7 M in contrast to cells cultivated in PBS, in the control group. Assessment of proliferation was performed after 24, 36, and 48 hours by counting cells using trypan blue exclusion method. Alkaline phosphatase was measured spectrophotometrically at 405 nm with paranitrophenol buffer. Results: After 48 hours, the number of Saos-2 cells increased significantly when subcultured with Bio-Oss. Bio-Oss was more effective on the enhancement of proliferation of Saos-2 cells when compared to the physiologic dose of Dexamethasone (P<0.05). Alkaline phosphatase activity increased in cells grown on Bio-Oss and dexamethasone 10-7M in contrast to cells cultivated in PBS control group. The greatest level of activity was observed in the group containing Bio-Oss after 48 hour. Conclusion: The significant increase of cell proliferation and alkaline phosphatase activity in cells cultured on Bio-Oss, compared to Dexamethasone-treated cells, suggests the important role of this bone substitute in promoting bone regeneration

Problem raspodjele kamiona smatra se jednim od najvažnijih čimbenika u postizanju planiranih proizvodnih kapaciteta u rudarstvu. Tradicionalne tehnike raspodjele kamiona (npr. matematičko programiranje, teorije čekanja u redu) podliježu različitim razinama pojednostavljenja u formuliranju stvarnoga prijevoza u heterogenim okolnostima. U ovome radu analiziran je problem raspodjele kamiona razvojem metode za optimizaciju raspodjele kamiona koja se temelji na simulaciji optimizacije (SBO) s obzirom na nesigurnosti tijekom rada kamionskoga voznog parka. Metoda osigurava integriranu strukturu simultanom kombinacijom optimizacije i simulacije stohastičkih diskretnih događaja. Ciljna je funkcija minimiziranje ukupnoga broja kamiona za transport sa simulacijom diskretnih događaja korištenih za modeliranje rubnih uvjeta. U ovome radu istražen je rad voznoga parka na primjeru rudnika bakra Sungun kako bi se postigla optimalna raspodjela kamiona pri različitim radnim operacijama na eksploatacijskome polju rudnika. Pojedinosti rada procijenjene su na temelju različitih pokazatelja kao što su iskorištenje, vrijeme čekanja i količina transportiranoga materijala za svaku radnu operaciju. K onačno, uska grla operacija prepoznata su za svaku situaciju.Truck allocation problems are considered as one of the most substantial factors in the achievement of planned production capacity in the mining industry. Traditional truck allocation techniques (e.g. mathematical programming, queueing theories) have undergone different levels of simplifications in formulating actual haulage operations under heterogeneous circumstances. In this study, the truck allocation problem is analysed through the development of the simulation-based optimization (SBO) method for the optimization of truck assignment considering uncertainties during fleet operation. This method provides an integrated structure by the simultaneous combination of optimization and stochastic discrete-event simulation. The objective function is to minimize the total number of trucks for haulage operation with discrete-event simulation employed to model the constraints. As a case study, the fleet operation of the Sungun copper mine is investigated to accomplish an optimal truck allocation for various working benches in the mine site. Operation details are evaluated through different indicators such as utilization, waiting times, and the amount of transported materials for each working bench. Finally, the operation bottlenecks are recognized for each situation
