An in-line oil-water separator has been designed and is investigated for singleand two-phase flow. Numerical single-phase flow results show an annular reversed flow region. This flow pattern agrees qualitatively with results from measurements. In the two-phase flow simulations two different drag laws have been used to model the interaction between the phases. The velocity field of the singleand...

The Chadegan metamorphic complex is a WNW-ESE- trending antiformal structure located in Sanandaj-Sirjan structural zone, Iran.The inner core of the structure is made of orthogneiss, containing eclogitic lenses. Schists and marbles lie structurally above theorthogneiss and crop out in the external limbs of the antiformal dome. Two main deformational episodes have been documented in theschists an...

In this paper, we investigated the athermal pressure behavior of the structural and elastic properties of scheelite BaWO4 phase up to 7 GPa using the ab initio pseudo-potential method. The calculated lattice parameters pressure relation have been compared with the experimental values and found to be in good agreement with these results. Moreover, we present for the first time the investigation ...

Maintaining weight loss after the initial phases of any weight loss intervention is a challenge. Rationally, it depends on how well the adherence is to the prescribed treatment. This study is to test the sustainability of an intervention in maintaining weight lost during Ramadan by using voluntary fasting. Methods: Two groups of respondents (Muslim women with body mass index (BMI) ≥ 25.0 kg/m2)...

The continued advances in distributed data intensive applications have formed an increasing demand for distributed commit protocols that are adaptive to large scale and dynamic nature of the applications to guarantee data consistency and integrity. Well known two-phase commit protocol and three-phase commit protocol and their variants do not provide scalability and flexibility desired for a wid...

Atomic commitment protocols are used to ensure the atomicity of atomic transactions. The best known and most widely used atomic commitment protocol is two phase commit (2PC). The main idea behind 2PC is to perform two rounds of voting under the guidance of a site acting as coordinator. The coordinator asks first for votes on whether to commit (yes vote) or abort (no vote) the transaction. The p...

Distributed database systems use commit protocols to ensure atomicity in case of distributed transactions and a wide variety of commit protocols have been proposed so far. Two–phase commit (2PC) is a widely accepted standard protocol for distributed transactions. But 2PC suffer from blocking problem due to which three-phase commit (3PC) protocol was proposed which is an extension of 2PC. This p...

A study of high-pressure bubble growth within liquid droplets heated to their limits of superheat is reported. Droplets of an organic liquid (n-octane) were heated in an immiscible nonvolatile field liquid (glycerine) until they began to boil. High-speed cine photography was used for recording the qualitative aspects of boiling intensity and for obtaining some basic bubble growth data which hav...

This paper proposes a compensation PWM technique for the extension of output voltage ranges in three-phase VSI applications using three shunt resistors. The proposed technique aims to solve the dead zone, which occurs in high modulation indexes. In the dead zone, two phase currents cannot be sampled correctly, so that the three-phase VSI cannot be operated up to the maximum output voltage. The ...
