ith the aging population and recognition that treatment of a patient’s pain is a key healthcare objective, more patients are taking pain medications that must be taken consistently to be effective. But at the same time, many of these same medications are subject to abuse. These benefits and dangers drive the need to test for patient compliance. Although urine has historically been the specimen ...
Preeclampsia is a common complication of pregnancy associated with high maternal morbidity and mortality and intrauterine fetal growth restriction. There is extensive evidence that the reduction of uteroplacental blood flow in this syndrome results from the toxic combination of hypoxia, imbalance of angiogenic and antiangiogenic factors, inflammation, and deranged immunity. Women treated for pr...
In this work, two compounds of isonicotinohydrazide organic class, namely (E)-N′-(1-(4-(dimethylamino)phenyl)ethylidene) (MAPEI) and (Z)-N′-(2-oxo-2, 3-dihydro-1H-inden-1-ylidene) (OHEI) were synthesized evaluated for corrosion protection N80 steel in a concentrated acidic medium (15 wt.% HCl) at temperature 303 K. The weight loss method (gravimetric method) electrochemical techniques, i.e., im...
R esearchers recently gathered at Tsinghua University in Beijing, China, to share their accomplishments at the 13th annual ACM Conference on Ubiquitous Computing. 1 This multidisciplinary conference featured advances in sensing technologies and activity-recognition algorithms, novel applications, and results from end-user evaluations. Smartphones continued to provide a versatile research platfo...

The target of our study is the Monarch Butterfly, which isknown for its multi-generational migration behavior: it mi-grates between southern Canada and Mexico over the courseof one year within three to four generations. In spite of manyreported studies, little is known about what influences theirmigration. We approach this subject by using an ecosystemmodel consisting of...
The paper gives the results of the project that is oriented on the usage of knowledge discoveries from production systems. Knowledge discoveries were used in the management of these systems. The simulation models of manufacturing systems were developed to obtain the necessary data about production. Data mining model was created by using of the specific methods and selected techniques for define...
The Ensembl project (http://www.ensembl.org) provides genome resources for chordate genomes with a particular focus on human genome data as well as data for key model organisms such as mouse, rat and zebrafish. Five additional species were added in the last year including gibbon (Nomascus leucogenys) and Tasmanian devil (Sarcophilus harrisii) bringing the total number of supported species to 61...
Video games designed for educational purposes often struggle to effectively connect concepts of interest to gameplay. We propose that to encourage players to mobilize knowledge resources for non-game settings such games must be representationally congruent. Representationally congruent games are construction games where the player builds and/or interacts with the game using primitives relevant ...
