Time Division

The radio spectrum is limited, but in urban and rural areas some bands of radio spectrum are idle in most of the time. Some bands of radio spectrum are occupied occasionally. On the other hand, some bands are excessively used. This paper propsed an adaptive time division Duplex (ATDD) technology to effectively improve the transmission delay in the large range ,such as the rural network in 802.22 network.

Background: The present age is the age of stress. Everybody is disturbed due to one or the other reason irrespective of their age. However, adolescents are more prone to psychological and sociological disturbances.Objectives:To assess the psychosocial problems in adolescents.Methods: The study was conducted in selected schools of urban and rural areas taking 100 participants each for boys and girls using convenient sampling method. The tool used was youth self report. The data collected was analyzed using appropriate statistical methods.Results: The study revealed that 48.5% adolescents were well adjusted; 47% were having mild psychosocial problems; 4% had moderate psychosocial problems and 0.5% had severe psychosocial problems.Conclusion: Adolescents irrespective of their living places had varying degrees of psychosocial problems.

The effectiveness and appropriateness of establishing speed limits on freeways and the spatial extent of the zones were studied. Of particular interest were 55-mph (88-km/hr) speed zones that exist in the transition between urban and rural areas (determined according to urban area boundaries). Three types of freeway segments (urban-55, fringe-55, and rural-65) were analyzed, and although the study was of comparatively small scale, the results generally showed that higher speeds do not lead to more numerous or serious accidents. Moreover, compliance with speed limits is not necessarily a good measure of safety. On the other hand, motorists are self-policing to a certain degree in that they drive at reasonable speeds given the design of the different types of freeways. It is suggested that artificially lowered speed limits without a clear need being established from engineering and safety perspectives will not yield impressive safety benefits.

SummaryUsing Australian records of human births for the first six decades of the twentieth century, the proportions of male and female births are studied in relation to the mother's age, the father's age, the parents' ages in combination, and certain other factors. The principal data used relate to the years 1931–55, during which over 3 million children were born, yet even so the significant features are not easy to discern.Masculinity tends to fall as the age of either parent increases. But it is only average or below if one parent is old while the other is young. For high masculinity, both parents must be young.The Australian data are available in a form which enables the sex ratio to be studied also in relation to (a) the season of the year; (b) urban and rural areas; (c) the different states of the Commonwealth; (d) births inside and outside marriage; and (e) single and multiple births. When the influence of the parents' ages is eliminated, however, it does not appear as though the sex ratio varies significantly with any of these factors.

The Adaptive Behavior Inventory for Children was individually administered to the parents of 660 children of various ethnic groups from both urban and rural areas. In addition, the other measures of the System of Multicultural Pluralistic Assessment were also administered. Criterion-related validity coefficients were determined and the performance of children of different ethnic status and community type was explored. Low to moderate validity coefficients were found. No significant differences were found as a function of ethnic status although urban children scored significantly higher on all of the areas. Implications of these results regarding cautions and directions for research were discussed.

Abstract There are three Passer species in Lesotho: House Sparrow P. domesticus, Cape Sparrow P. melanurus, and Grey-headed Sparrow P. diffusus. The House Sparrow is an introduced species, recorded first in Lesotho in 1954. Today, all three species are very numerous (as dominants or subdominants) in urban and rural areas in all ecozones in the country. With an increase of altitude the proportion of Cape Sparrows in relation to the other sparrow species increases, while the reverse is true for the Grey-headed Sparrow. The proportion of House Sparrows appears to be only slightly affected by altitude. In some areas, the House Sparrow may displace the Grey-headed Sparrow.

Cerro Colorado

The research carried out in a period of two years, in the district of Cerro Colorado starts from the possibility of incorporating the values found in permaculture towards the development of a sustainable habitat in the studied sector, with an area of 174.51 ha and a population of 197,954 inhabitants, containing this territory both urban and rural areas, which makes the proposed methodology have several interconnected layers, ranging from the social-anthropological to geography and demography, to show the superposition of territorial domains. On the other hand, territorial plans have different scales that comprise a certain range of density of inhabitants, their components being mostly dimensional, where the so-called invisible structures are not considered. The investigation had concrete results, such as the social segregation generated and the lack of protection in landscaped areas, concluding that, among other aspects, there is no support for agriculture and that there are no housing development plans.
