In this paper, we inspect the stable geometry of thin-shell wormholes in the background of static spherically-symmetric AdS black holes solution bounded by dark fluid and Chaplygin-like equation of state [Formula: see text], where [Formula: see text] and [Formula: see text] denote the pressure and energy density that are related through positive constant [Formula: see text]. For this purpose, we consider the two equivalent copies of black holes and connected them at the hypersurface through cut and ...

In this experimental study, low viscosity (<5 mm2.s−1) ternary micro-emulsification fuels contain 50% petro-diesel, 30% waste frying oil and 20% n-butanol or iso-propanol. To observe the effects of ternary fuels on the characteristics of a turbocharged, common rail direct injection diesel engine, the engine tests were performed at the fixed engine speed of 2000 rpm and five different engine loads (BMEP: 3.3–10.0 bar). The results show that brake specific fuel consumption increased about 18% while thermal ...

Bipolar disorder (BPD) is a major psychiatric disorder with an unclear pathophysiology. Peripheral blood samples are easily drawn, making them are good candidates for diagnosing diseases. MicroRNAs are small non-coding RNA transcripts that regulate gene expression by binding to the 3′- UTR of mRNAs and directing their degradation. The aim of this study was to use blood plasma to investigate microRNA dysregulations in bipolar manic and euthymic patients. Blood samples were collected from 58 patients ...

Glycerol is a major byproduct of biodiesel production and it is used in many areas of application such as solketal production. Solketal is an alternative fuel for gasoline engines. Solketal addition into gasoline provides better fuel characteristics and especially an increase in octane number. In this study, detailed fuel properties of solketal-gasoline fuels were characterized according to fuel standards specified in EN 228. Pure gasoline and the blend containing 9% solketal were used as test fuels. ...

In this study, animal fat based biodiesels produced in the pilot plant were blended with certain amounts of diesel fuel and bioethanol. Neat biodiesels, diesel fuel and the blends were tested in a direct injection diesel engine and engine performance, combustion and exhaust emission characteristics were investigated. Engine tests were conducted at constant engine speed (1400 rpm) and four different engine loads (150 Nm, 300 Nm, 450 Nm and 600 Nm). The engine tests showed that the brake specific fuel ...

Objective The synaptosomal-associated protein of 25 kDa (SNAP-25) gene is a presynaptic plasma membrane protein and an integral component of the vesicle docking and fusion machinery mediating secretion of neurotransmitters. Previously, several studies reported association between SNAP-25 and attention deficit hyperactivity disorder (ADHD). We investigated whether these SNAP-25 polymorphisms (MnlI T/G and DdelI T/C) were also associated with ADHD in the Turkish population. Methods Our study comprised ...

Contrast-induced nephropathy (CIN) is a frequent, potentially lethal complication of percutaneous coronary interventions (PCIs). We prospectively validated the diagnostic performance of a simple CIN risk score in a large multicenter international cohort of patients who underwent PCI. About 2,882 consecutive patients treated with elective or urgent PCI were enrolled. A simple CIN risk score was calculated for all patients by allocating points according to a prespecified scale (pre-existing renal disease = ...

Abstract Aniseed spirits are produced by the distillation of pressed fermented grapes, dregs and other fermented raw materials, flavored with aniseed (Pimpinella anisum L), fennel (Foeniculum vulgare) and/or some other plants. All round the Mediterranean basin, there are other similar aniseed spirit drinks such as pastis (France), anesone (Spain), sambuca (Italy), zebib (Egypt), and arak (Syria). However, there are some differences between the production processes of these spirits and their traditional ...

Abstract Biogenic amines are low molecular weight organic compounds that occur in fermented foods and are produced mainly through the microbial decarboxylation of amino acids. Decarboxylation of several amino acids can form some biogenic amines in wines such as histamine, tyramine, putrescine, and phenylethylamine. Biogenic amines can cause direct or indirect toxicity when their concentrations are high in food. The enological importance of the biogenic amines in wines is due to their possible toxicological ...

In the surgical history of hepatic hydatid disease, multiple scolicidal agents have been used for sterilization of the cyst contents. However, none of these agents can be safely used, because most have unacceptable side effects, such as toxicity, caustic sclerosing cholangitis, bile duct stricture, and hypernatremia. Protoscolices were aseptically removed from liver hydatid cysts obtained from sheep slaughtered at the municipal abattoir in Kahramanmaras, Turkey. In this study, the effects of 0.9% ...

Abstract It is hypothesized that molecular components of dopaminergic system, especially the dopamine D3 receptor gene (DRD3), may play a crucial role in the pathophysiology of schizophrenia, because it is abundant in the limbic system of the brain and it binds antipsychotic drugs. Several groups attempted to find an association between a serine‐to‐glycine polymorphism of the DRD3 gene (Ser9Gly) and schizophrenia; however, the results were inconsistent. In this study, we aimed to investigate the relationship ...
