This article considers a linear regression model when a set of exact linear restrictions binding the coeecients is available and some observations on the study variable are missing. Estimators for the vectors of regression coeecients are presented and their superiority properties with respect to the criteria of the variance covariance matrix and the risk under balanced loss functions are analyzed.

Leaves of cotton (Gossypium hirsutum L.) accumulate considerable dry mass per unit area during photosynthesis. The percentage of C in that accumulated dry mass was estimated as the regression coefficient (slope) of a linear regression relating C per unit area to total dry mass per unit area. Plants were grown on full nutrients or on N- or P-deficient nutrient solutions. In the fully nourished c...

To describe and compare the clinical outcome of infants born to mothers with gestational and pregestational diabetes mellitus, this study was conducted between January 2000 to January 2002 in Tehran vali-E-- -Asr Hospital. Among 4472 deliveries, we found 107 infants born to diabetic mothers out of whom 6 were twins. The prevalence of diabetes in total deliveries was 2.39%. Mean age of gesta...

Abstract Female reproductive success depends to a large extent on infants’ ability survive maturity. While most studies of female have focused the effects individuals’ sociodemographic factors (e.g., age/parity, dominance rank) offspring survival among wild primates living in less disturbed habitats, little research has urban or periurban animals. Here we investigated and anthropogenic determin...

Infants avoid touching plants. Here we examine for the first time whether infants are also reluctant to touch plant foods. We hypothesized that would foods because food neophobia-the avoidance of novel foods-is particularly strong fruits and vegetables. However, predicted processed a lesser degree than whole leafy plants they bear markers previous human engagement. In assessment, presented 7- 1...

Background & Aims: The purpose of the present study was to compare feeding problems, infant eating behavior, and feeding styles between infants with and without feeding problems according to their mothers’ narratives. Methods: In this casual-comparative study, 50 mother-infant dyads were selected using convenient sampling. The infants’ ages ranged between 6 to 12 months. After matching, the inf...

Background: Infants are exposed to different painful procedures during hospitalization in the neonatal intensive care unit (NICU). Due to the harmful effects of pain on infants, NICUs require methods by the aid of which the pain in infants can be controlled. Yakson touch and oral glucose are among non-pharmacological methods for pain relief in infants. In this regard, the present study was cond...
