We study binary linear codes constructed from fifty-four Hadamard 2-(71, 35, 17) designs. The constructed codes are self-dual, doubly-even and self-complementary. Since most of these codes have large automorphism groups, they are suitable for permutation decoding. Therefore we study PD-sets of the obtained codes. We also discuss the errorcorrecting capability of the obtained codes by majority l...

Mean-preserving and covariance preservingmatchings are introduced that can be obtained with conditional, randomized matching on sub-populations of a large control group. Under moment conditions it is shown that these matchings are, respectively, equal percent bias reducing (EPBR) and variance proportionatemodifying (PM) for linear functions of the covariates and their standardizations. The resu...

Arizona is the first state in the nation to regulate agricultural practices in order to reduce dust emissions near urbanizing areas. This BMP program requires dust mitigation actions in some combination of tillage and harvest, crop land, and non-crop land activities. Contingent valuation methods were used to estimate the willingness-to-adopt reduced tillage equipment. At $10-26 per acre in long...

The cyclic treatment technique (redox cycling) comprising stages of material exposition in reducing and oxidizing high-temperature environments and intermediate degassing between these stages has been developed to improve the structural integrity of YSZ-NiO ceramic anode substrates for solid oxide fuel cells. A series of specimens were singly reduced in a hydrogenous environment (the Ar-5 vol% ...

The breast-feeding practices of a series of postpartum women, who had undergone prior reduction mammaplasty by means of an inferior pedicle approach, are reported in this retrospective study. Also identified are the factors that influenced the decision to breast-feed postoperatively. From a patient pool of 544 individuals who elected to have reduction mammaplasty between 1984 and 1994 (age rang...

Carpal tunnel syndrome (CTS) is the most common compressive entrapment neuropathy caused by the compression of the median nerve at the wrist space known as the carpal tunnel. The epidemiologic factors related to CTS include genetic, medical, social, vocational, and demographic factors. The common symptoms experienced include pain, paresthesia, and numbness in the median nerve distribution. If l...

climate change phenomenon is an important environmental challenge of the world that has increased its speed with the increasing extension of greenhouse gases and remote relationship phenomena. changes in precipitation level, drought occurrence and in the level of surface and groundwater resources are the recognized consequences of climate change. in order to study climate change phenomenon cons...
