Let X be a definable C manifold, Y1, Y2 definably compact definable C r submanifolds of X such that dimY1 + dimY2 < dimX and Y1 has a trivial normal bundle. We prove that there exists a definable isotopy {hp}p∈J such that h0 = idX and h1(Y1) ∩ Y2 = ∅. 2010 Mathematics Subject Classification. 14P10, 14P20, 58A05, 03C64.

Project-based learning is an essential part of a software engineer's education. The learning achieved through projects can be improved through structured interaction between more experienced students and those students encountering their rst software engineering project. In this paper, we report on our experience over three years with trials of several forms of interaction between undergraduate...

Future system development and management efforts must strive to institutionalize these gains and provide ongoing, incremental improvement in these areas. With the growth of e-commerce and further socioeconomic reliance on IT, the organizations that have achieved these gains will be well positioned to outdistance those who were less aggressive. Figure 1 depicts the silver linings and competitive...

ARCINOMA OF THE LUNG IS AN EVERC incre-g public health problem. h a general hospital such as Charity Hmpital of New Orleans, Louisiana, it is probably the most common carcinoma in men. It is &mated that one out of t h m deaths in men between 50 and 60 years of age is due to bmnchogenic carcinoma,' Tumor registry records have been kept at Charity Hospital in New Orleans since January 1, 1948. Fr...

The assessment of the quantitative and qualitative changes, the result of the impacts imposed by natural factors, and human interventions during specific sampling periods has a substantial influence on nature, management method and tending operation of every region’s forests. The present research was carried out in Golestan province forests (Iran) over an 11- year period and the obtained statis...

 Background: Ovarian masses represent a range of pathology from benign cyst to highly aggressive malignant tumors. It has been estimated that gynecologic malignancy account for approximately 2% of all types of cancer in children, 60-70% of these lesions arise in the ovary.  Methods: All ovarian masses which were resected or biopsied in Mofid Children's Hospital from 2002 to 2012 were reviewe...

Background: Unintentional drug intoxication is still a major cause of mortality and morbidity in young children. Method & Materials: In order to study changes of epidemiological indices of children intoxication during a 10-year period in Hamadan Province, all cases admitted to Ghaem Hospital from 1995-1999 were recruited, and compared with all cases admitted to the same hospital from 1990-1...

We used functional magnetic resonance imaging (fMRI) to investigate the psychological refractory period (PRP), the delay in the response to the second of two tasks occurring in immediate succession. Our results were consistent with prior work on the PRP in that when two visual-manual tasks were presented within 100 ms of each other, the second response was delayed on the order of 500 ms, compar...

It has been argued that the psychological refractory period (PRP) effect is eliminated with two ideomotor compatible tasks when instructions stress fast and simultaneous responding. Three experiments were conducted to test this hypothesis. In all experiments, Task 1 required spatially compatible manual responses (left or right) to the direction of an arrow, and Task 2 required saying the name o...

In this paper we discuss general properties of geodesic surfaces that are (locally) biLipschitz homogeneous. In particular, we prove that they are locally doubling and there exists a special doubling measure analogous to the Haar measure for locally compact groups.
