Abstract: production and breeding records from 6,877 lactations of 4,673 cows were used to evaluate the effect of adjusting for previous days open on genetic evaluations. predicted breeding values for kg of milk were calculated using three animal models. model 1 - contained no adjustment for days open and accounted for the fixed effects of herd-year-season, genetic group, age of calving (covariate) and the random effects of animal, permanent environment effect and error; model 2 - same as one with previous days open included; model 3 - production records were standardized to 100 days open before using model 1. predicted breeding values from each model were compared. cows in the 2% top had their ranks changed nine and 11 places for models 2 and 3, respectively, when compared to their rank from model 1. furthermore, eight and 11 cows dropped from the top 2%, when evaluated with models 2 and 3, both accounted for days open. the reliabilities of the predicted breeding values for the three models were almost equal. the rank correlations between estimated breeding values for cows and sires for all models were near one. therefore, adjustment for previous days open did not change the rank of animals in this genetic evaluation for holsteins in the state of minas gerais.

Abstract: the objective of this work was to verify if it is necessary to adjust the 305-day milk yield for yield in the early lactation in determining the effect of days open on milk production. the yields in early lactation were represented by the cumulative yield up to 80, 100 or 120 days and summit production. the analyses were conducted for the first and following lactation using models that accounted for present and previous days open, respectively. an animal model for 305-day milk yield included the fixed effects of herd-year-calving season, genetic group, age of cow and days open in classes, early lactation yield and the random effects of animal, permanent environmental and error. when early lactation yield was included for the first lactation cows, the relative differences of each days open class, for example, 160 days, remained practically unalterable. for example, as the initial yield were up to 80 to 100 days, the relative differences among cows with 40 to 160 days of the present days open were 675 and 677 kg, respectively. when early lactation yield was ignored this difference was of 672 kg. for the following lactation of the cows, there was no effect of the variation of early lactation time on the relation between milk production and previous days open. the estimated heritability value for milk production was 0.24, when there was no adjustment and, decreased to 0.15, when summit production was considered. it was concluded that it is not necessary to account for early lactation yield on adjusting milk production for days open.

Abstract: the main method recognized by the metrologists for the evaluation of measurement uncertainty is de facto the guide to the expression of uncertainty in measurement (iso guide). due to some limitations of the proposed method by iso guide however, iso has developed a supplementary method for evaluating the measurement uncertainty based on the propagation of probability density functions using the monte carlo method (iso-s1). the present paper discusses these methods for the quantification of measurement uncertainty. we review the literature, in particular the main papers presenting these modern approaches. we also discuss the merits and the limitations of the iso guide and iso-s1 approaches. furthermore, a comparative study between these two methods was carried out in two case studies. the obtained results show that it is necessary to evaluate the influence of the degree of non linearity in order to estimate the measurement uncertainty before either method is chosen

Abstract: The growth and expansion of economies of developing countries rely, in a great extension, on the access to financing sources for entrepreneur activities. Capital markets are one of the most efficient alternatives for local companies to have access to capitals, either local or foreign, and, therefore, for the boosting of the economic progress of such countries. In this sense, a legal framework of capital markets that fulfill the requirements of stability, certainty and security are essential in order to countries to compete for international capitals and investments. Indeed, such requirements are imperative to grow an environment of confidence of investors. Among other important issues in the capital markets regulation scope, there are two that have a vital importance to induce the confidence of investors and, consequently, to attract investment: the legal protection of investors and the regulation of the activities of credit rating agencies. It is vital that the legal system sets a framework for the protection of investors in the capital markets. The need of a stable, clear and secure framework does not imply an excessive intervention of the state in the ability of private economic agents to regulate their own interests. On the contrary, the state shall only provide for the minimum content of the financial services agreement and assure the compliance of the obligations taken under a contract. Furthermore, as the investment decisions made by economic agents rely mostly on the information they have on the financial instruments that are offered in the market, rules determining the full disclosure of information are essential. Concerning credit rating agencies, it is important to understand the role that such entities have undertaken in capital markets. Information about companies and financial instruments is the material economic agents use to make their investment decisions. But the cost to process and analyze the whole bunch of available data is too high for most agents, so they have to rely on the opinion of experts, such as credit rating agencies. In this context, regulation shall assure that the aforementioned agencies act in a fair and transparent way. Rules concerning conflict of interests, publicity of the criteria of rating analysis, and supervision on the activities of agencies are important to the growth of a sound capital market and an investment friendly environment. The article will focus on some of the production-centered jurisdictions—Argentina, Brazil, Chile, Colombia, Mexico, and Venezuela. They were chosen because they are the major

Abstract: type 1 diabetic patients frequently present hypoglycemic episodes during their insulinotherapy, which, besides the discomfort and constrains does not allow the ideal glycemic control. further, hypoglycemic events lead to the deficiency of the counter-regulation mechanisms in the subsequent episode, with a decrease in the release of epinephrine and the symptoms of warming, with great risk of severe hypoglycemia. the occurrence of hypoglycemia during some risky activities, specially driving, could result in accidents with the patient and /or third parts including property damage, stressing here the need to advise diabetics against having the necessary caution wheli driving. generally the connective recovery is total after correcting a hypoglycemic coma. however when these episodes are repetitive, particularly in children, they could result in definitive cognitive disturbances. hypoglycemic events without a warning signal (hypoglycemic unawareness) are difficult to reverse, thus it is necessary to prevent their occurrence, adjusting the treatment with glycemic targets, using continuous glucose monitoring at home and teaching them how to have an early recognition of hypoglycemia.

Abstract: 153,963 test day milk yield records and 13,273 first lactations of holstein cows calving between 1989 and 1998, were used with the objective of estimating genetic, phenotypic and environmental parameters for test day milk yield (pldc) and 305 day milk yield (p305) and to study the convenience of using test day yields in genetic evaluations to replace p305. four models were used. models 1 and 2 differed according contemporary grouping and monthly milk records were considered as repeated measures. in model 1 (pldcm01) records were grouped by herd-year-season of test day yield and in model 2 (pldcm02) by herd-year-season of calving. in a third (model 3), monthly yield records were analyzed as individual traits (c01 to c10); and the fourth (model 4) was the traditional 305-day model. restricted maximum likelihood methodology was used with the mtdfreml system. the estimates of heritability for pldc, using model 1, model 2 and for p305 were 0.27, 0.15 and 0.25, respectively. heritabilities for monthly milk records ranged from 0.11+0.02 (c01) to 0.21+0.03 (c08), with the largest values occurring beginning in the fourth month. genetic correlation estimates between monthly records and p305 ranged from 0.76 to 1.00, with the highest correlations occurring in the middle lactation. it was concluded that using test day milk yield is promising and that selecting for middle lactation records could have advantages over 305-day milk yield.
