A uniform mesh finite difference method for a class of singular two-point boundary value problems

Manoj Kumar, Tariq Aziz

Sep 1, 2006 in Applied Mathematics and Computation
A method is described based on a uniform mesh for the class of singular two-point boundary value problems ( x α y ′ ) ′ = f ( x , y ) , 0 x ⩽ 1 . y (0) = A , y (1) = B . It is shown to be order h 4 convergent for all α ∈ (0, 1).


Hypovascular pancreas head adenocarcinoma: CT texture analysis for assessment of resection margin status and high-risk features.

Ameya Kulkarni et 8 al.

Jan 17, 2020 in European radiology
To determine if CT texture analysis features are associated with hypovascular pancreas head adenocarcinoma (PHA) postoperative margin status, nodal status, grade, lymphovascular invasion (LVI), and perineural invasion (PNI). This Research Ethics Board-approved retrospective cohort study included 131 consecutive patients with resected PHA. Tumors were segmented on preoperative contrast-enhanced CT....


Identification and Adjudication of Adverse Events Following Rectal Cancer Surgery: Observational Case Series in a Region of Ontario, Canada.

Marko Simunovic, G R Baker et 14 al.

Sep 5, 2021 in Annals of surgical oncology
For patients undergoing rectal cancer surgery, we evaluated whether suboptimal preoperative surgeon evaluation of resection margins is a latent condition factor-a factor that is common, unrecognized, and may increase the risk of certain adverse events, including local tumour recurrence, positive surgical margin, nontherapeutic surgery, and in-hospital mortality. In this observational case series o...

Biotransformation of linoleic acid into different metabolites by food derived Lactobacillus plantarum 12-3 and in silico characterization of relevant reactions.

Tariq Aziz, Zhennai Yang et 6 al.

Jun 3, 2021 in Food research international
Lactic acid bacteria have been reported to be capable of converting polyunsaturated fatty acids, e.g. linoleic acid (LA) into bioactive and other fatty acid metabolites that are not toxic to the bacteria themselves, but the mechanism of this conversion is not clear. Here we reported for the first time that probiotic L. plantarum 12-3 derived from Tibet kefir when supplemented with LA from 1% to 10...

Separation of Storage Proteins (7S and 11S) from Soybean Seed, Meals and Protein Isolate Using an Optimized Method Via Comparison of Yield and Purity.

Jalal Ud Din, Xinqi Liu et 7 al.

Apr 24, 2021 in The protein journal
The primary purpose of this study was to extract β-conglycinin (7S) and glycinin (11S) from soybean seed, soybean meals and soybean protein isolate and compare their yield and purity. The previous methods were modified for the extraction and isolation of 7S and 11S globulins. The adjustment mainly included sample to solution ratio of 1:10 (previously 1:15). Comparing the yield of 11S fraction in T...

Water stable graphene oxide metal-organic frameworks composite (ZIF-67@GO) for efficient removal of malachite green from water.

Habib Ur Rehman Shah, Tariq Aziz et 6 al.

Jun 5, 2021 in Food and chemical toxicology
Malachite green (MG) is extensively applied in aquaculture worldwide as a therapeutic agent. MG and its primary metabolite leucomalachite green (LMG) are commonly detected in aquaculture products. MG can cause serious health concerns (in vivo carcinogenic/genotoxic). The extensive water solubility of MG leads to water pollution and hence it is mandatory to remove MG from water. The current study e...


Assessing the pharmacological and biochemical effects of Salvia hispanica (Chia seed) against oxidized Helianthus annuus (sunflower) oil in selected animals.

Tariq Aziz et 8 al.

Feb 27, 2023 in Acta biochimica Polonica
Oil oxidation is important in terms of taste, nutritive component quality and toxic effect of the oil. In this study, the oxidized sunflower oil was used along with chia seed in rabbits for the determination of its effects on various hematological and serum biochemical parameters as well as on liver histopathology. Three rabbits were fed with oxidized oil (obtained by heating) at the dose rate of ...


Kinetic and Thermal Study of Ethylene and Propylene Homo Polymerization Catalyzed by ansa-Zirconocene Activated with Alkylaluminum/Borate: Effects of Alkylaluminum on Polymerization Kinetics and Polymer Structure.

Amjad Ali, Li Guo et 11 al.

Jan 15, 2021 in Polymers
The kinetics of ethylene and propylene polymerization catalyzed by homogeneous metallocene were investigated using 2-thiophenecarbonyl chloride followed by quenched-flow methods. The studied metallocene catalysts are: rac-Me2Si(2-Me-4-Ph-Ind)2ZrCl2 (Mt-I), rac-Et(Ind)2ZrCl2 (Mt-II) activated with ([Me2NPh][B(C6F5)4] (Borate-I), [Ph3C][B(C6F5)4] (Borate-II), and were co-catalyzed with different mol...

Challenges associated with cellulose composite material: Facet engineering and prospective.

Tariq Aziz, Pau Loke Show et 10 al.

Apr 15, 2023 in Environmental research
Cellulose is the most abundant polysaccharide on earth. It has a large number of desirable properties. Its low toxicity makes it more useful for a variety of applications. Nowadays, its composites are used in most engineering fields. Composite consists of a polymer matrix and use as a reinforcing material. By reducing the cost of traditional fibers, it has an increasing demand for environment-frie...

Role of silica-based porous cellulose nanocrystals in improving water absorption and mechanical properties.

Tariq Aziz, Pau Loke Show et 12 al.

Apr 1, 2023 in Environmental research
Epoxy resins are important thermosetting polymers. They are widely used in many applications id est, adhesives, plastics, coatings and sealers. Epoxy molding compounds have attained dominance among common materials due to their excellent mechanical properties. The sol-gel simple method was applied to distinguish the impact on the colloidal time. The properties were obtained with silica-based fille...
