Salmonella remains a threat to both animal and public health. Its economic significance remains high and changes in public perception mean that some measures for control may be necessary even in the absence of financial loss. Diagnosis is an important part of control. A great deal of new information has become available over the last few years as a result of research into various aspects of bot...

Mammalian mitochondrial DNA (mtDNA) is inherited principally down the maternal line, but the mechanisms involved are not fully understood. Females harboring a mixture of mutant and wild-type mtDNA (heteroplasmy) transmit a varying proportion of mutant mtDNA to their offspring. In humans with mtDNA disorders, the proportion of mutated mtDNA inherited from the mother correlates with disease sever...

t sounds like a paradox, but there is only one real trend evident in today's global market, and that is continuous – and rapid – change. The market environment is uncertain; competitors are changing; new, disruptive technologies are emerging; and topping all this, customers are becoming more demanding. To be successful in such a dynamic market, globally operating companies must be able to suppl...

The objective was to assess the vitamin D status in healthy 12-month-old infants in relation to quantity and sources of dietary vitamin D, breastfeeding and seasons. Subjects were 76 12-month-old infants. Serum levels of 25-hydroxyvitamin D (25(OH)D) ≥ 50 nmol/L were considered indicative of vitamin D sufficiency and 25(OH)D < 27.5 nmol/L as being indicative of increased risk for rickets. Addit...

0494 On 26 December 2004, Sri Lanka was affected, along with many other countries in the region, by deadly tsunami waves. The estimated death toll in Sri Lanka was more than 40,000; many more thousands of people were missing and displaced. Sri Lanka had not experienced a disaster of such magnitude in its 2,000 years of recorded history. The administrative, health, and judicial services were sim...

We give an algorithm for generating cyclic self-orthogonal (CSO) codes for an arbitrary positive integer n with gcd(n; q) = 1. Given a cyclic q-ary code of length n, we determine how many codes isomorphic to the given code are cyclic. We introduce a mass formula for CSO(n; q) codes of maximum dimension. Using the mass formula we classify CSO(63; 2) codes. This mass formula works for any cyclic ...

We show that a recently proposed algorithm ([9]) for decoding cyclic codes may be applied efficiently to all binary cyclic codes with t ≤ 2 and n < 63.

Recent research has dramatically advanced our understanding of soil organic matter chemistry and the role of N in some organic matter transformations, but the effects of N deposition on soil C dynamics remain difficult to anticipate. We examined soil organic matter chemistry and enzyme kinetics in three size fractions ([250 lm, 63–250 lm, and \63 lm) following 6 years of simulated atmospheric N...

UNLABELLED Abnormalities of zinc homeostasis are indicated in many human diseases. A noninvasive imaging method for monitoring zinc in the body would be useful to understand zinc dynamics in health and disease. To provide a PET imaging agent for zinc, we have investigated production of (63)Zn (half-life, 38.5 min) via the (63)Cu(p,n)(63)Zn reaction using isotopically enriched solutions of (63)C...
