The spruce beetle, Dendroctonus rufipennis (Kirby), is an important mortality agent of native spruces throughout North America. The life-cycle duration of this species varies from 1 to 3 years depending temperature. The univoltine cycle (one generation per year) is thought to maximize outbreak risk and accelerate host mortality in established outbreaks. Prepupal diapause is associated with the ...

introduction: over the past two decades, the incidence of cesarean section in most countries has increased.developmental delay occurs when children do not reach their developmental milestones at the expected time. the main causes of developmental delay are often unknown. investigation of the prevalence of developmental delay and its effective factors in children from 4 to 12 months old in pakda...

Lateral inhibition represents a well-studied example of biology's ability to self-organize multicellular spatial patterns with single-cell precision. Despite established biochemical mechanisms for lateral inhibition (e.g., Delta-Notch), it remains unclear how cell-cell signaling delays inherent to these mechanisms affect patterning outcomes. We investigate a compact model of lateral inhibition ...

Deformational plagiocephaly and craniosynostosis are two of the most common neonatal cranial head shape anomalies. Traditionally, both entities were thought to cause aesthetic concerns solely. Recently, many groups have demonstrated that both conditions are strongly associated with developmental delays. The relationship between the abnormal neonatal cranial shape and early developmental delays ...

Parents of children with developmental delays experience increased levels of parental stress, often related to the severity of their child’s behaviour. However, the experience of stress is dependent on how individuals perceive their situation and whether coping strategies (i.e., problem-focused, emotionfocused, and appraisalor perception-focused coping) are used to manage stress. Forty-six pare...

Background: The variability in the developmental skills is reduced after the first three years of life; therefore, it is necessary to identify and manage early developmental delays. Aim: The aim of this study was to investigate the effect of developmental stimulation program on the developmental measures of the toddlers. Method: The present randomized controlled clinical trial was conducted on ...

Early identification of children with developmental delays is important in the primary care setting. The pediatrician is the best-informed professional with whom many families have contact during the first 5 years of a child’s life. Parents look to the pediatrician to be the expert not only on childhood illnesses but also on development. Early intervention services for children from birth to 3 ...
