Introduction: The importance of breast-feeding is well-known over the first two-year of the life. Although, the complementary feeding is the main source of energy during the above-mentioned period and breast-feeding itself cannot supply the child nutritional requirements, as a consequence, complementary feeding provides seventy percent of the daily child requirements. It seems that a decrease i...
there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...
(2) Our campus squirrel population provides ample opportunities to explore squirrel feeding preferences or scatterhoarding behaviors. Many of the findings summarized in a series of papers by Steele and Smallwood (e.g., “What are squirrels hiding? Natural History 10: 40-44. 1994. and other findings reported in their articles) offer challenging field experiment ideas. For example, given that spec...
The most common site of cancer in women is breast, and breast cancer is the second cause of death in women fortunately, breast self exam (BSE) is a simple, noninvasive rout to early diagnosis of this fatal disease. So, in order to assess the knowledge level of the mentioned groups about (BSE) we conducted a descriptive, cross-sectional study and 428 subjects within which 208 patients, 155 st...

Pilot studies play an important role in health research, but they can be misused, mistreated and misrepresented. In this paper we focus on pilot studies that are used specifically to plan a randomized controlled trial (RCT). Citing examples from the literature, we provide a methodological framework in which to work, and discuss reasons why a pilot study might be undertaken. A well-conducted pil...
We present a method for exploiting the symmetry in the planning graph structure and certain redundancies inherent in the Graphplan algorithm, so as to improve its backward search. The main insight underlying our method is that due to these features the backward search conducted at level k + 1 of the graph is essentially a replay of the search conducted at the previous level k with certain well-...
BACKGROUND Conventional pharmaco-cavernosography provides little information on penile venous anatomy, although it is indispensible in documenting veno-occlusive erectile dysfunction (ED). We propose an innovative method, which may provide additional insight into the penile venous structure. METHODS From July 2010 to November 2012, 96 impotent men, aged 20 to 75 years, underwent this method o...
