this study is an attempt to answer three questions: first, whether there is a difference between the grammatical competence de- velopment of a group of children aged 2;6 vs. a group of children aged 3;6. second, whether there is a relationship between the children’s age and their mlu on the one hand and their speech and the caretakers’ speech on the other. third, whether or not the normal limit...

For fixed t ≥ 2, we consider the class of representations of 1 as sum of unit fractions whose denominators are powers of t or equivalently the class of canonical compact t-ary Huffman codes or equivalently rooted t-ary plane “canonical” trees. We study the probabilistic behaviour of the height (limit distribution is shown to be normal), the number of distinct summands (normal distribution), the...

OBJECTIVES To determine the period prevalence, demographic characteristics, cost of treatment, and outcomes of patients admitted to the intensive care unit for continuous renal replacement therapy. DESIGN Descriptive case series. SETTING Intensive Care Unit in a Hong Kong tertiary referral, teaching hospital. PATIENTS All patients admitted to the Intensive Care Unit from January to Decemb...

In men over 30 years old, serum levels of testosterone (T) decrease with age. A shorter polymorphic CAG repeat length in exon 1 of the androgen receptor (AR) gene is associated with higher transcription activation by the AR. We determined the number of CAG repeats for 882 men aged between 40 and 70 years from the Massachusetts Male Aging Study (MMAS). MMAS is a population-based random sample su...

In this study, the perceived speed of a tilted line translating horizontally (for a duration of 167 msec) is evaluated with respect to a vertical line undergoing the same translation. Perceived speed of the oblique line is shown to be underestimated when compared to the vertical line. This bias increases: (1) when the line is further tilted, (2) with greater line lengths, (3) with lower contras...

OBJECTIVES Due to the high incidence in our service, we did object on this study describe the features and outcome of patients with systemic lupus erythematosus (SLE) admitted to the intensive care unit of Walter Cantídio University Hospital METHODS Patients were restrospectively characterized according to demography parameters, time of diagnosis of SLE, organ dysfunction and laboratorial par...

OBJECTIVE To determine whether the degree of cervical lengthening after cerclage and whether serial follow-up measurements of cervical length after cerclage are predictive of pregnancy outcome. METHODS Eighty women whose primary physician determined that a prophylactic (n = 50) or urgent cerclage (n = 30) was indicated had transvaginal ultrasonographic evaluation before and after cerclage. Th...

Consider the unit circle C and a circular arc A of length l = |A| < 1. It is shown that there exists k = k(l) ∈ N, and a schedule for k runners with k distinct but constant speeds so that at any time t ≥ 0, at least one of the k runners is not in A.
