In the present work, interactions between a macro-crack and various micro-crack configurations are studied extensively. Influence of different on propagation main crack is numerically examined by ordinary state-based peridynamics. Certain improve toughness specimens, while some only has marginal impact growth rate. Furthermore, very complex patterns effectively simulated implementation formulat...
Studies of Air-Sea Gas Transfer and Micro Turbulence at the Ocean Surface using Passive Thermography
Knowledge about the mechanisms of mass transfer across the aqueous boundary layer is still marginal because of the lack of suitable experimental techniques. We present a new technique to measure the air-water gas transfer rate and the spatial structure of the micro turbulence at the ocean surface using passive thermography. We make use of the fact that due to radiative cooling, latent and sensi...
Nutritional status of sixty women, who were either marginal farmers or landless agricultural workers were assessed by diet survey, anthropometry and estimation of haemoglobin levels. Diet survey carried out by the 24 hour recall method revealed adequate intake of calories and protein but low intake of micronutrients. While intake of vitamin C and the B vitamins were poor, iron and vitamin A wer...
The standard New Keynesian model suffers from the so-called .macro-micro pricing conflict: in order to match the dynamics of inflation implied by macroeconomic data, the model needs to assume an average duration of price contracts which is much longer than what is observed in micro data. Here I show how departing from the standard model’s assumption of a perfectly competitive labor market can h...
background and aim: an important criterion for success assessment of implant-supported prostheses is marginal fit. vertical and horizontal discrepancy can result in loosening of the prosthetic screw, crestal bone resorption, peri-implantitis and loss of osseointegration. despite careful attention to waxing, investing, and casting, marginal discrepancies are inevitable. the aim of this study was...
objective: this experimental in vitro study compared marginal adaptation of indirect composite, glass-ceramic inlays and direct composite. materials and methods: seventy-five recently extracted human molars were randomly divided into three groups (n=25) and mesio-occluso-distal cavities with the same dimensions were prepared in the teeth. indirect composite and glass-ceramic inlays were fabrica...
Today, the use of micro-computed tomography is becoming widespread in almost every field dental research. When national review articles on are examined, it seen that focus endodontic and surgical applications. As prosthodontists, our article, which was compiled order to deepen specific usage areas applications studies done this area, provides information about method prosthetic dentistry. Micro...
This paper considers some fundamental questions concerning marginally trapped surfaces, or apparent horizons, in Cauchy data sets for the Einstein equation. An area estimate for outermost marginally trapped surfaces is proved. The proof makes use of an existence result for marginal surfaces, in the presence of barriers, curvature estimates, together with a novel surgery construction for margina...
This research combined three distinctly unique and separate measures of corruption into one corruption factor, so as to yield a robust measurement approach to further understand the political and socioeconomic variables of corruption. The findings show that a strong significant variable in measuring corruption is the personal marginal-tax rate, especially in hierarchical based nations. The high...
Connecting prostheses to the implant abutments has become a concern and achieving a satisfactory retention has been focused in cement-retention prostheses recently. Sandblasting is a method to make a roughened surface for providing more retention. The aim of this study was to compare effects of nano and micro airborne abrasive particles (ABAP) in roughening surface of implant abutments and furt...
