This paper focuses on the effect of fluid injection into the wall boundary layer on the flashback propensity of a hydrogen-air jet burner. For this purpose, an experiment with a tube burner was designed, where the flame is anchored in the free atmosphere at the burner exit. Pure air was injected through an annular gap at three streamwise ...
Experimental Investigation on the Effect of Replacement of. Experimental Investigation on the Effect of Replacement of Sand by Quarry Dust in Hollow Concrete Block for Different Mix Proportions H. S.

Nitinol has become a new type of biomedical material due to its shape memory effect, super elasticity, and good biocompatibility. At present, nitinol cardiovascular stents are mainly made by laser cutting, but the surface quality after laser cutting is poor, which causes thermal damage, residual stress, heat-affected zone, and recast layer. This situation seriously affects …
To verify the damping improvement by replacing partial sand with rubber powder in the concrete process, this study investigated the effects of the rubber powder (5%, 10%, 15%, and 20%) on the mechanical properties and micromechanism of polyvinyl alcohol (PVA) fiber-reinforced concrete. In addition, in order to discuss its damping …
Single point incremental forming (SPIF) is a sheet metal forming process used to obtain customized products with complex shapes. A hemispherical tool producing a series of local plastic deformations leads to increase in the formability of the final product. However, this forming technology still carries some drawbacks. The investigation of SPIF in terms of quality …

Replacement tiles were selected based on similarity in algal standing
E Perimental Analysis Of Crushing Effect Is Broken. Due to the high permeability of water flow in crushed rocks flow catastrophes and water inrush accidents are apt to take place in the broken zones of aquifers in coal mining engineering The pore crack and fracture geometries needed for water transport are strongly influenced by grains diameter ...
The demand of natural sand in the construction industry has increased a lot resulting in the reduction of sources and an increase in price. Thus an increased need to identify a suitable substitute, that is eco-friendly and inexpensive quarry dust being extensively used as an alternative to the sand in the production of concrete. In this paper an attempt has been made …
In this study, three mixtures containing fillers (microsilica slurry, quicklime, and combination of cement and quicklime) with slow setting bitumen emulsion, and the mixture of cement filler, as the control mixture, were used for laboratory survey and comparison of the effects of different fillers on the performance of microsurfacing asphalt ...
Aliabdo, A.A. et al. [5] studied the effect of partially replacing cement by marble slurry for two water binder (w/b) ratios 0.40 and 0.50. Increase in compressive strength for up to 7.5% replacement for w/b ratio 0.5 and slight increase in compressive strength for up to 10% replacement for w/b ratio 0.40 was reported.
Swallow Studies . Retrospectively 5 swallow studies were randomly selected for inclusion in this study. The demographics of the study patients are found in Table 1.The Modified Barium Swallow Impairment Profile (MBSImP ™ ©, Northern Speech Services, Gaylord, MI) standards were used for the clinical MBSS[].Eleven single swallows of standardized, commercial preparations of …
In this experimental work, the effect of partially replacing of glass powder in concrete is studied. The cement in concrete is replaced by waste glass powder in steps of 10% 20%, 30%& 40% respectively by volume of cement and its effects on compressive strength, split tensile strength, workability and flexural strength are
Solutions at a minimum value of surface tension during the treatment period were selected for the test group and non-magnetized solutions were used as the control group. Each test tube was injected with 1 ml of solution and the penetrating effect was observed after 2 h. 3. Results3.1. Magnetic-field effect on nonionic surfactant solution properties
The effect of water cement ratio on hardened properties of cement mortar with partial replacement of natural sand by manufactured sand was also reported[3]. M. Prem Anand et. al. have reported the results of experimentally investigation on the effect of M-Sand in structural concrete by replacing river sand and develop a high performance concrete.
2.2. Fabrication and testing. Woven E-glass fiber fabric of 300 g/m 2 along epoxy resin LY556 and hardener HY951 mixed in appropriate ratio of 1:10 at room temperature. Hand layup technique was used followed by vacuum bagging process. Filler particulates of 5, 10 and 15 percentage and Volume fiber fraction of 60% was taken into account.
Unexpected changes may cause unpredictable behavior of the transducer and a dramatic loss of performances. This paper experimentally investigates the effect of different working conditions on quality factor, bandwidth, resonance of a Terfenol-D resonance transducer that works in its first mode of vibration.
Aim: This pilot study was designed to assess the effect of an essential oil antiseptic mouthrinse (EOM) in reducing bloodstream bacteria after chewing an apple. Material and methods: From a panel of 200, we screened 62 individuals with mild-to-moderate gingivitis. Twenty-two individuals who showed a bacteraemia after chewing an apple were enrolled.
Section 232 Investigations: The Effect of Imports on the National Security. Section 232 of the Trade Expansion Act of 1962 (19 U.S.C. §1862) authorizes the Secretary of Commerce to conduct comprehensive investigations to determine the effects of imports of any article on the national security of the United States.
In addition, financial communication satisfaction mediated the relationship between each of the financial conflict message patterns and marital satisfaction. The current study lays empirical groundwork for developing a theoretical framework for understanding marital interaction patterns and the effects these patterns have on marital satisfaction.
The May 9 notice specified that the Secretary of Commerce initiated an investigation to determine the effects on the national security of imports of aluminum. This investigation has been initiated under section 232 of the Trade Expansion Act of 1962, as amended. (See the May 9 notice for additional details on the investigation and the request ...
