We propose a layout algorithm for micro/macro graphs, i.e. relational structures with two levels of detail. While the micro-level graph is given, the macro-level graph is induced by a given partition of the micro-level vertices. A typical example is a social network of employees organized into different departments. We do not impose restrictions on the macro-level layout other than sufficient t...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
during recent decades, researchers have attempted to understand individual and group level behavior, at micro levels while macro level researchers studied organizational and institutional level behavior. yet few scholars have examined organizational effects on individual and group behavior and the effects of individual and group behavior on organization as a whole. such a research can lead to a...
BACKGROUND Determination of vancomycin minimum inhibitory concentration (MIC) can influence the agent used to treat methicillin-resistant Staphylococcus aureus (MRSA) infection. We studied diagnostic accuracy using E-test and VITEK(®) 2 against a gold standard broth microdilution (BMD) methodology, the correlation between methods, and associations between vancomycin MIC and MRSA phenotype from ...
A liquid-impelled reactor (LLR) system was modelled using macro-and micro-balance technique. The relative goodness of using macro-balance was evaluated by comparing its solutions with the results obtained using micro-balance modell. The micro-balance modell formulated was used to investigate the dynamic behaviour of the system and to crosscheck the effectiveness of macro-balance modell. A numer...
The increased potential for soil erosion and compaction due to continuous row crop production and intensive tillage is causing some concern and has led to the consideration of reduced tillage techniques as part of the solution. The objective of this study was to investigate the short-term (one-year) influences of different management practices on the physical properties of a sandy loam soil und...
in order to determine calcium (ca), magnesium (mg) content and total antioxidant capacity (tac) of seminal plasma in buffalo and to study their associations with the semen characteristics, 54 semen samples were collected from 10 buffalo bulls; semen quality was evaluated, seminal plasma was then harvested by centrifugation and its ca and mg content were estimated and its tac determined. the ca ...
Purpose: The purpose of the present study was to investigate the effects of thyroid gland pathology on macro and trace elements of teeth. Methods: We examined two groups of patients: healthy patients and patients with thyroid disorders. The sample was comprised of 32 extracted teeth for orthodontic and periodontal indications from patients 18 to 50 years old. The changes in macro and micro trac...
a r t i c l e i n f o This paper presents a Bayesian Network (BN)-based modeling method for cascading crisis events. Crisis events have occurred more frequently in recent years, such as typhoons, rainstorms, and floods, posing a great threat to humans. Addressing these crises requires a more effective method for crisis early-warning and disaster mitigation in crisis management. However, few mod...
