Nowadays most of the wireless sensor network management modes have a shorter lifetime because adopting the way of transferring management information to each other, which thus consuming energy too fast. This paper Present a new modal based on mobile agent for wireless sensor network scluster management.this model can make up the shortcoming of the nowadays wireless sensor networks management ar...

This study aimed to identify standards and expectations regarding sexual initiation of 14 to 18 year-old adolescents in Sao Paulo, SP, Brazil, using data from four focal groups conducted in 2006. Results revealed that gender issues are clearly present in participants' reports and showed to be essential in their choices about the moment, partners and contraceptive practices in the first sexual r...

The Lactobacillus (Doderlein's bacillus) (Wilson and Miles, 1964) had been regarded as the preponderant micro-organism in the vagina, at least after puberty. During the 1960s a re-examination of the microbiology of the vagina was prompted by the widespread use of potent antibacterial agents and of oral contraceptives (Krupp and St. Romain, 1960; Morris and Morris, 1967; Morris, 1969). During th...

BACKGROUND & OBJECTIVES The unique immunological functions of γδ T lymphocytes to contribute immunity against Mycobacterium tuberculosis attracted interest of researchers. However, little is known about the specificity of γδ Τ cell in tuberculosis patients and the lack of exact tuberculosis antigen recognized by γδ T cells limited its application. The analysis of complementary determinant regio...

Approximately one third of women who are diagnosed with malignant melanoma are of childbearing age. Therefore, it is not surprising that some studies have found malignant melanoma to be one of the most common malignancies diagnosed in pregnant women. The impact of pregnancy-related hormonal changes on melanoma development and progression remains controversial. Women undergo immunologic changes ...

The development of Intelligent Environments is a complex challenge. This complexity arises, in part, from the amount of different devices that need to be seamlessly integrated in a common and homogeneous environment, despite the fact of each device having its own characteristics. This heterogeneity of devices is particularly risky when one passes from the specification to the implementation pha...

Twenty four lines were crossed with two testers in an L x T mating design to estimate the combining ability for seed yield in sunflower. Non-additive genetic variance played a preponderant role in the inheritance of all the characters studied viz., days to 50 % flowering, days to maturity, plant height, head diameter, volume weight, hundred seed weight and seed yield per plant. The lines 27, 43...

Background noise has become part of our everyday life in modern societies. Its presence affects both the ability to concentrate and communicate. Some individuals, like children, the elderly, and non-native speakers have pronounced problems in noisy environments. Here we review evidence suggesting that background noise has both transient and sustained detrimental effects on central speech proces...

In higher plants, most of the chlorophyll a is formed via the divinyl and monovinyl chlorophyll monocarboxylic biosynthetic routes. These two routes are strongly interconnected prior to protochlorophyllide formation in barley (Hordeum vulgare L. cv Morex), a dark monovinyl-light divinyl plant species, but not in cucumber (Cucumis sativus L. cv Beit Alpha MR), a dark divinyl-light divinyl plant ...

To investigate the relationship between atomic topology, vibrational and electronic properties and superconductivity of bismuth, a 216-atom amorphous structure (a-Bi216) was computer-generated using our undermelt-quench approach. Its pair distribution function compares well with experiment. The calculated electronic and vibrational densities of states (eDOS and vDOS, respectively) show that the...
