Rheological Investigation on the Effect of Shear and Time Dependent Behavior of Waxy Crude Oil

MATEC Web of Conferences, 2014
Rheological measurements are essential in transporting crude oil, especially for waxy crude oil. Several rheological measurements have been conducted to determine various rheological properties of waxy crude oil including the viscosity, yield strength ...

SPHINX31 acts as a SRPK1 inhibitor targeting the ATR/DNA‐PKcs/CHK1 replicative checkpoint to inhibit cell growth in non‐small cell lung cancer

Molecular Oncology, EarlyView.
The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.

Ultrasonic Detection and Analysis of Wax Appearance Temperature of Kingfisher Live Oil

, 2015
Wax crystallization is a serious problem because it may result in the plugging of wellbores, production facilities, and transportation pipelines during oil production. This study describes the use of a novel high-pressure ultrasonic detection system as a

Investigations of temperature and dilution effect on rheological properties of waxy crude oil

Journal of Petroleum Exploration and Production Technology, 2019
The purpose of the paper is to study the effect of temperature and hydrocarbon solvent addition on thixotropy of waxy crude oil. Oil is a complex multicomponent hydrocarbon system. There are many interactions between wax and asphaltene, wax and aromatics,

Review on Mitigation of Paraffin Wax Formation using Jatropha-Based Inhibitor

Platform, a Journal of Engineering
Wax deposition in pipelines and wells is one of the problems in the oil and gas industry. Wax deposition can lead to pipeline blockages, reduced flow capacity, and even production facility or pipeline closures.

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

FEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Investigating Non-Uniformity of Wax Appearance Temperature of Crude Oil in Nigeria

A significant sample of crude oil found in Niger Delta have between moderate to high wax content which makes flow process sometimes difficult at low temperatures due to the formation of gel-like structure which increases viscosity of the fluid.
