Wideband CDMA systems with orthogonal spreading codes suffer severely due to the loss of orthogonality by multipath propagation. This yields Multiple Access Interference (MAI) which gravely reduces the performance of classical systems with Rake-receivers. In our approach we attempt to restore orthogonality again by using a fractional T-equalizer. The results are compared with a system using the...

President Barack Obama has concluded that success in Afghanistan depends upon enhanced coordination along the entire range of national power. To achieve this, he has ordered former CIA officer Bruce Riedel, Ambassador Richard Holbrooke, and Undersecretary for Defense Policy Michele Flournoy to lead a review of US policy. As they work through the mechanics of military, diplomatic, and developmen...

The Bandar Bushehr, Iran earthquake of April 9, 2013 gravely illustrates how disaster-prone areas of the world are compounding their risk of disaster and major public health emergencies when there is a geographical convergence of natural and technological hazards. Scientists must emphasize to policy makers that ever-increasing regional industrialization and the broader introduction of nuclear f...

A 15-year-old male developed features of Still's disease. He was treated, with incomplete response, with aspirin and corticosteroids. Some 10 months after the onset he contracted chickenpox and became gravely ill. A diagnosis of histiocytic medullary reticulosis was made because erythrophagocytic histiocytes were detected in marrow aspirate films. Necropsy studies showed systemic infiltration b...

Neurologists cautioned that the new report characterized only a single, perhaps unique case and that it did not mean that unresponsive brain-damaged people were more likely to recover or that treatment was possible. The woman in the study could not communicate with the researchers, and there was no way to know whether her subjective experience was anything like what healthy people call consciou...

Background: Sand production is an important factor affecting reservoir exploitation. Excessive sand production affects the oil well life, causes the damage to the oil recovery device and brings serious hidden danger in the process of safety production. Objective: This paper presents a sand content computation model for the crude oil, which uses the power of sand production and Parseval theorem,...

Impaction is defined as the failure of a tooth to erupt in its appropriate site in the dental arch within its normal period of growth (Preda et al., 1997). The frequency of individual based permanent tooth eruption disturbances is 20% the overwhelming majority of impacted teeth involve third molars, followed by maxillary canines and the mandibular second premolars (Grover and Lorton, 1985). Max...

A new wolf spider genus, Serratacosa gen. nov., is erected based on the type and species, S. medogensis et sp. nov. two newly combined himalayensis (Gravely, 1924) (from Hogna Simon, 1885) multidontata (Qu, Peng & Yin, 2010) Pardosa C.L. Koch, 1847). All of them are from southern slopes Eastern Himalayas. Descriptions genera a redescription provided together with digital images, illustratio...

Gravely calcareous soils cover approximately most of arid lands (in percent); however, the solute transport behavior in these soils remains a current issue. This research aimed at estimating and correlating the solute transport parameters in gravely calcareous soils as being affected by different land uses through the knowledge of the soil morphological, physical, and chemical properties. Four ...
