introduction: cloacal malformation is an extremely rare fetal pathological condition but an important anomaly that presents as a variety of defects. it predominantly affects females, with prevalence of 1 in 50,000 births. prenatal ultrasonography usually showed oligohydramnios and the fetus having a large cystic mass in the lower abdomen with a single septum, bilateral hydronephrosis, ambiguous...

In order to understand the behaviour of distributed program environments, this paper describes a threedimensional visualization of communications. Most of previous visualizations presented communications by means of two dimensions of time and process, however, three dimensions are required to represent a message intermediary with visualization functions. We make use of a semantic configuration ...

Mucocele is a common salivary gland disorder that can appear in the lacrimal sac, paranasal sinuses, oral cavity, appendix, or gall bladder. These lesions occur due to mucous accumulation resulting from the alteration of minor salivary glands. Lower lip is the most common site of occurrence of these lesions in the oral cavity and most probable cause is trauma or habit of lip biting. Diagnosis i...

In this paper, we establish a new lower bound for Mathieu’s series and present a simple and short proof of the Mathieu’s inequality. We also give a simple derivation of the integral form of the series.

We give new information about the relationship between the lowdimensional homology of a group and its derived series. This yields information about how the low-dimensional homology of a topological space constrains its fundamental group. Applications are given to detecting when a set of elements of a group generates a subgroup “large enough” to map onto a non-abelian free solvable group, and to...

purpose : to evaluate the retinal nerve fiber layer (rnfl) and central corneal thickness (cct) in patients with exfoliation syndrome (xfs) methods : in this comparative case series we measures rnfl thickness and cct 30 patients with xfs and 30 age and sex matched healthy subjects who met the inclusion criteria. results : average rnfl in xfs group were significantly thinner than controls (94.36±...

this study investigated the manifestation of bloom’s revised taxonomy (brt) in two series of young and adult teaching persian to speakers of other languages (tpsol) textbooks. to this end, the contents of the textbooks were analyzed based on a coding scheme. the results showed statistically significant differences between the different volumes of young learners’ series and between the two serie...
