We consider the offline scheduling problem of minimizing the makespan on m parallel and identical machines with certain feature. Every job and machine are labeled with the grade of service (GoS) levels, and each job can only be processed by the machine whose GoS level is no more than that of the job. In this paper, we present a polynomial time approximation scheme (PTAS) with running time O(n l...

Abstract Background There are several surgical strategies involved in the treatment of patients with tentorial meningioma, and choosing most appropriate one is not straight forward. Our study aims to illustrate our experience management meningiomata at center. Results This included 32 meningiomas, operated upon, assessment extent resection Glasgow outcome score (GOS). The mean age time surgery ...

The properties of rubber compounds used in tire tread largely contribute to the overall performance tires vehicles. Among various ingredients used, reinforcing fillers are known for having most significant effect on static and dynamic compounds. In this work, two strong nanoscale materials, aramid nanofibers (ANFs) graphene oxides (GOs), modified using a silane coupling agent combined form nove...

The proposed cis-Golgi vesicle receptor syntaxin 5 was found in a complex with Golgi-associated SNARE of 28 kDa (GOS-28), rbet1, rsly1, and two novel proteins characterized herein: rat sec22b and membrin, both cytoplasmically oriented integral membrane proteins. The complex appears to recapitulate vesicle docking interactions of proteins originating from distinct compartments, since syntaxin 5,...

β-Galactosidase from Streptococcus thermophilus was overexpressed in a food-grade organism, Lactobacillus plantarum WCFS1. Laboratory cultivations yielded 11,000 U of β-galactosidase activity per liter of culture corresponding to approximately 170 mg of enzyme. Crude cell-free enzyme extracts obtained by cell disruption and subsequent removal of cell debris showed high stability and were used f...

β-Galactosidase was immobilized on chitosan-coated magnetic Fe3O4 nanoparticles and was used to produce galactooligosaccharides (GOS) from lactose. Immobilized enzyme was prepared with or without the coupling agent, tris(hydroxymethyl)phosphine (THP). The two immobilized systems and the free enzyme achieved their maximum activity at pH 6.0 with an optimal temperature of 50 °C. The immobilized e...

BACKGROUND The scale and diversity of metagenomic sequencing projects challenge both our technical and conceptual approaches in gene and genome annotations. The recent Sorcerer II Global Ocean Sampling (GOS) expedition yielded millions of predicted protein sequences, which significantly altered the landscape of known protein space by more than doubling its size and adding thousands of new famil...

This study was aimed to investigate the effect of mineral matter of Göynük oil shales (GOS) on pyrolysis and product evolution. Organic part was separated from mineral matter before pyrolysis in an isothermal pyrolysis reactor. In the demineralization step, carbonate, pyrite and silicates were removed from kerogen by using HCl, HNO3 and HF, respectively. Thereafter all samples were pyrolized in...

OBJECTIVE Removal of blood from subarachnoid space with a lumbar drainage (LD) may decrease development of cerebral vasospasm. We evaluated the effectiveness of a LD for a clinical vasospasm and outcomes after clipping of aneurysmal subarachnoid hemorrhage (SAH). METHODS Between July 2008 and July 2013, 234 patients were included in this study. The LD group consisted of 126 patients, 108 pati...

OBJECTIVE To clarify the prognosis of the patients with intra-sylvian hematoma (ISH) and intracerebral hematoma (ICH) in ruptured middle cerebral artery (MCA) aneurysms. METHODS We categorized hematoma into ISH and ICH by the presence of intra-hematomal contrast enhancing vessel (IHCEV) on computed tomography angiography (CTA). Forty-four ruptured MCA aneurysm patients with ICH or ISH were gr...
