this research was carried at the university of reading in 1999. the aim was to estimate the effects of 18 hd-1 (long-day, ld) and 12 hd-1 (short-day, sd) light exposure duration of plants before bolting or flowering on time to bolt and flower in two bolting susceptible (bsg, ic1) and bolting resistant (brg, saxon) genotypes of sugar beet. so, two experiments were conducted. the experiments were...

background polycystic ovarian syndrome (pcos) is the most common hormonal disorder in reproductive-age women. this syndrome is associated with many complications, so treatment of the disorder is usually warranted. objectives to evaluate the effects of a combined low-dose oral contraceptive (ld) and vitex agnus on the improvement of clinical and paraclinical parameters of pcos. methods this trip...

We compared the diagnostic efficacy of the ratios LD-1/LD-2, LD-1/LD-3, LD-1/LD-4, and LD-1/LD-5 in 69 documented cases of myocardial infarction. We used 149 patients with congestive heart failure and 67 patients with nonmyocardial infarct as controls. We used a computer program to produce receiver-operating characteristic curves, decision threshold plots, and likelihood ratios for these LD rat...

IPX066 (extended-release carbidopa-levodopa [ER CD-LD]) is an oral extended-release capsule formulation of carbidopa and levodopa. The single-dose pharmacokinetics of ER CD-LD (as 2 capsules; total dose, 97.5 mg-390 mg CD-LD) versus immediate-release (IR) CD-LD (25 mg-100 mg), sustained-release (CR) CD-LD (25 mg-100 mg), and CD-LD-entacapone (25 mg-100 mg-200 mg) was evaluated in healthy subjec...

Define an augmented LD-system, or ALD-system, to be a set equipped with two binary operations, one satisfying the left self-distributivity law x ∗ (y ∗ z) = (x ∗ y) ∗ (x ∗ z) and the other satisfying the mixed laws (x ◦ y) ∗ z = x ∗ (y ∗ z) and x ∗ (y ◦ z) = (x ∗ y) ◦ (x ∗ z). We solve the word problem of the ALD laws, and prove that every element in the parenthesized braid group B• of [2, 3, 5...

Twenty five blood samples from 6-month to 5-year old children with visceral leishmaniasis were analysed for various enzymes. Aspartate transaminase (AST), alanine transaminase (ALT), lactate dehydrogenase (LD) and its various isoenzymes were estimated in the serum, while glucose 6-phosphate dehydrogenase (G6PD) was measured in red blood cells. For comparison, blood samples from healthy chi...
