Background: Pre-eclampsia along with bleeding and infection constitute a triad that is a major cause of maternal mortality. Many factors have been recognized which can help us to determine the severity of the disease and early diagnosis of it. Since throphoblastic disorder is one of the etiological causes of pre-eclampsia, we decided to measure the level of β-hCG as a marker of detecting the ac...

We consider the NP-complete problem of deciding whether an input graph on n vertices has k vertex-disjoint copies of a fixed graph H . For H = K3 (the triangle) we give an O(2 2k log n) algorithm, and for general H an O(2k|H| log k+2k|H| log |H|n|H|) algorithm. We introduce a preprocessing (kernelization) technique based on crown decompositions of an auxiliary graph. For H = K3 this leads to a ...

A length n group code over a group G is a subgroup of G under component-wise group operation. Group codes over dihedral groups DM , with 2M elements, that are two-level constructible using a binary code and a code over ZM residue class integer ring modulo M , as component codes are studied for arbitrary M . A set of necessary and sufficient conditions on the component codes for the two-level co...

This paper examines different linearization techniques which are used to linearize the power amplifier by emphasizing on weakness and strength of each technique. After complete analyze it has been concluded that Digital Pre Distortion (DPD) technique is the best linearization technique to linearize the power amplifier. DPD technique for linearizing a wideband radio frequency power amplifier has...

The excretion rates of the C19-mineralcorticoids, 16beta-hydroxy-DHEA and 16-oxo-androstenediol, were measured in subjects with low-renin essential hypertension and toxemia of pregnancy. C19-mineralocorticoid excretion in low-renin essential hypertension ranged from 70-790 microgram per day. No significant difference in 16beta-hydroxy-DHEA and 16-oxo-androstenediol excretion was found between t...

objective: the present research was conducted to study the effect of play therapy on reducing behavioral problems of children with oppositional defiant disorder. method: using multistage cluster sampling, regions 6, 7, and 8 in tehran were selected. among kindergartens of these areas, 3 kindergartens which were supported by the welfare organization were randomly selected. of all the pre-school ...

Spontaneous Anonymous Group (SAG) Cryptography studies cryptographic problems in which an entity specifies a group of entites including itself arbitrarily and spontaneously while maintaining its anonymity. There is no Trusted Third Party (TTP) or group manager to get involved. Also, no membership collaboration or any preprocessing is needed.These properties are desirable for many applications r...

In this paper the capacity achievable by Abelian group codes when employed over symmetric channels is determined. For certain important examples, like the AWGN channel with m-PSK modulation, it follows that this capacity coincides with the corresponding Shannon capacity of these channels. In other words using Abelian group codes in this case there is no loss of capacity (as it happens for binar...

Background and Aims: Preeclampsia is one of the causes of maternal mortality whose leading cause is still unknown. This study was conducted to investigate the relation between blood group and pre-eclampsia in primipara women. Materials and Methods: This case-control study was performed on 100 pirmipara women in Gonabad city. The samples were assigned, by census, into two groups of case (with p...
