2. Comparison between dexmedetomidine and fentanyl bolus in attenuating the stress response to laryngoscopy and tracheal intubation: a randomized double-blind trial
Abstract Background and objectives: Laryngoscopy and tracheal intubation lead to a sympathoadrenal response. We compared the efficacy of dexmedetomidine with fentanyl bolus to attenuate this response. Methods: One hundred patients admitted for routine surgical procedures under general anesthesia were enrolled in this double blind, randomized, controlled st

3. Molecular characterization of yeasts isolated from traditional Turkish cheeses
Abstract Thirty-two yeast strains were identified by means of molecular methods isolated from traditional Turkish cheeses (Tulum, Kashkaval, Mihalic, Orgu, White, Sepet, and Goat). Debaryomyces hansenii and Torulaspora delbrueckii were found as predominant species in cheese samples. Other species which were identified were Kluyveromyces lactis, Candida parap

4. THERMODYNAMIC PROPERTIES OF TAMARIND SEEDS (Tamarindus indica L.)
ABSTRACT Tamarind is used in the food and pharmaceutical industry, and its seed is the main means for the reproduction of this species, thus justifying studies that ensure its post-harvest viability. This research aimed to study the thermodynamic properties of tamarind seeds as a function of the equilibrium moisture content. The experimental data of the wate

5. CLASSIFICATION OF ROBUSTA COFFEE FRUITS AT DIFFERENT MATURATION STAGES USING COLORIMETRIC CHARACTERISTICS
ABSTRACT Coffee growers who produce the robusta species (Conilon) have sought to increase productivity and drink quality by improving production techniques. Artificial vision systems can assist in increasing the efficiency of operations associated with crop management. This study aimed to obtain colorimetric characteristics of robusta coffee fruits at differ

10. Glass Formation of Null-Matrix Cu-Hf-(Zr, Ti) Alloys
An approach following the null-matrix, Ti/Zr ratio of 2.08, for neutron diffraction was used to calculate the glass formation in Cu-Ti-(Hf,Zr) alloys. The Cu55Zr14.6Ti30.4, Cu61.48Hf18.52Zr6.48Ti13.52, Cu58.1Hf16.9Zr8.1Ti16.9 and Cu52.46Hf14.2Zr10.8Ti22.54 compositions (at. %), were calculated and prepared by argon arc melting. Copper die suction casting was

11. The Surface Treatment of Niobium Superconducting Reentrant Cavities by Means of High Temperature Nitrogen Plasma Based Ion Implantation
High Temperature Nitrogen Plasma Based Ion Implantation (HT-NPBII) has been used to treat the surface of niobium superconducting reentrant cavities, which are part of parametric transducers in a resonant-mass gravitational wave detector. The aim is to enhance the corresponding electrical quality factors (Q-factors) which are closely related with the increase

12. ENERGY PERFORMANCE IN DISC HARROWING OPERATION IN DIFFERENT GRADIENTS AND GAUGES
ABSTRACT The operational performance of the agricultural tractor can be increased by adjusting parameters such as tire inflation pressure, axle mass distribution and gauge opening, which is a very divergent factor in controlled-traffic production. The objective of the experiment was to measure the energy performance of a 93 kW agricultural tractor in interme
