Critical sets of full Latin squares
… the properties of critical sets of the full n-Latin square and related combinatorial structures including full designs, (m,n,2)-balanced Latin rectangles and n-Latin cubes. In Chapter 3 we study known results on designs and the analogies between critical sets of the full n-Latin square and …

Randomization analysis of experimental designs under non standard conditions
… examine the impact on the expectations of mean squares, treatment means, and treatment differences for two model mis·specifications: Systematic response shifts and correlated experimental units. Systematic response shifts are presented in the context of the randomized complete block design …

Combined intra- and inter-block analysis for factorials in incomplete block designs
… block designs, group divisible designs, and Latin Square types of partially balanced, incomplete block designs. For the class of Latin Square sub-type L₃ designs both the intra-block and combined intra- and inter-block analyses have been developed. In general, factorial treatment combinations …

Subconstituent Algebras of Latin Squares
Let n be a positive integer. A Latin square of order n is an n×n array L such that each element of some n-set occurs in each row and in each column of L exactly once. It is well-known that one may construct a 4-class association scheme on the positions of a Latin square, where the relations are the …

Approximate Transversals of Latin Squares
<p>A latin square of order <em>n</em> is an <em>n</em> by <em>n</em> array whose entries are drawn from an <em>n</em>-set of symbols such that each symbol appears precisely once in each row and column. A transversal of a latin square is a subset of cells that meets each row, column, and symbol …

The Effects of Atropine Sulfate on Flight Simulator Performance and on Respiratory-Heart Period Interactions (Human, Electrocardiogram, Organophosphorous)
… doses of 0.5, 1.0, 2.0, and 4.0 mg/75 kg in a Latin Square double blind design, and effects were monitored for 3 hr post-injection.

Effects of source and amount of energy and protein on ruminal fermentation, nutrient passage to the small intestine, and performance of lactating Holstein cows
… four Holstein cows were used in a 4 x 4 Latin square with treatments arranged in a 2 x 2 factorial.

Evaluation of chitinous materials as a feed for ruminants
… ruminating calves in two replications of a 3 x 3 Latin square design. In each 4-week period, nitrogen balance data was collected during the third week. Crabmeal nutritive value was established. It substituted equally for base ration at the levels studied. No treatment differences were detected for …

Nutritional Strategies for Optimizing Nitrogen Utilization by Dairy Cows
… the diet. Experiment 1 was designed as a 6 x 6 Latin square to examine the effects of the percentage and source of CP and the amount of starch in the diet of dairy cows on ruminal fermentation, passage of nutrients to the small intestine, and nutrient digestibility. Two sources of CP (soybean …

Amino acid requirements of growing steers
… casein or mixes of crystalline amino acids simulating the nonsulfur amino acid pattern of casein, both with and without 12 g/d abomasally infused L-methionine (4 replications/treatment). Nitrogen retention increased linearly in response to casein infusion and in response to infusion of the amino …

Efficacy of guanidinoacetic acid supplementation to growing cattle and relative bioavailability of guanidinoacetic acid delivered ruminally or abomasally
… Holstein steers (280 ± 14 kg) in a 5 × 5 Latin square design and evaluated relative bioavailability of GAA. Treatments were continuous ruminal or abomasal infusion of 0, 10, or 20 g/d GAA, and blood and urine samples were collected on the final day of each period for analysis of creatine, …

Lactation Response of Dairy Cows Fed Distillers Grains Versus Oilseed Meals
… A lactation trial was designed as a 4 x 4 Latin square design with 4 wk per period utilizing 12 cows. Distillers grains with solubles were included in the diets at 0, 12, 24, and 36% on a dry matter basis. The diets consisted of 49% forage and 51 % concentrate on a dry matter basis. Diets …
