Drilling fluid is the most important lifeline of the drilling operation, that main task is facilitate the cuttings removal of the drilling. There are varieties of drilling fluids such as sodium bentonite based-drilling fluid is called “mud” and drilling foam or surfactant based-drilling fluid is called “soap”. The present work aims are study on the modified drilling mud properties by using the ...
Acute bee paralysis virus (ABPV) is a small single stranded RNA virus recently classified within the family Dicistroviridae, genus Cripavirus. Here, we describe the first study of ABPV in unhealthy bee colonies, which has been an unusual loss in adult bee population and significant honey bee mortality during the year. The aim of this study was evaluation of ABPV infection in honey bee colonies ...
Background: Having precisely analyzed the data of patients with specific diseases we can obtain the patterns and knowledge of these disease or even specific characteristics of patients. A hypothesis is usually considered in medical studies when some data are gathered prospectively to prove or deny this hypothesis, but in many cases there may be relationships between the data of the patients w...
Introduction & Objective: Chronic periodontitis is an inflammatory disease of the tooth supporting tissues by a specific group of microorganisms, leading to progressive destruction of the periodontal ligament. The aim of this study was to evaluate the effect of amoxicillin and metronidazole as an adjunct, after scaling and root planning in reducing pocket depth and clinical attachment loss in...
field studies were conducted during the cotton crop seasons in 2003 and 2004 at ccs haryana agricultural university, hisar, to identify mortality factors in the egg stage of helicoverpa armigera (hübner) (lepidoptera: noctuidae) in the insecticide-free cotton fields to gain an insight into the role of these factors in causing egg specific mortality. eggs were collected from cotton fields on dif...
Polyvinyl ester green composites were synthesized with walnut shell powder (WSP) by in-situ polymerization technique. The green composites have been evaluated for mechanical properties such as tensile strength, tensile modulus and hardness. Sliding wear loss, specific wear rate and coefficient of friction were investigated by using computerized pin-on–disc machine at normal applied loads of 20,...
In this paper, two training systems for selecting PLIP parameters have been demonstrated. The first compares the MSE of a high precision result to that of a lower precision approximation in order to minimize loss of information. The second uses EMEE scores to maximize visual appeal and further reduce information loss. It was shown that, in the general case of basic addition, subtraction, or mul...
Background: Amblyaudia, a recent subcategory of auditory processing disorder, is characterized by asymmetrical auditory processing of an individual’s ears. Amblyaudia can result in speech comprehension difficulties, reading difficulties, information processing deficits, and inattention. These difficulties can be mistakenly attributed to Attention Deficit Hyperactivity Disorder, Specific L...
