Why does commitment vary?
For vector-borne parasites such as malaria, how withinand between-host processes interact to shape transmission is poorly understood. In the host, malaria parasites replicate asexually but for transmission to occur, specialized sexual stages (gametocytes) must be produced. Despite the central role that gametocytes play in disease transmission, explanations of why parasites adjust gametocyte pro...
متن کاملمفهوم نظارت در اصل 99 قانون اساسی
قانون اساسی مهمترین سند و میثاق مدون ملی است که عمل به آن در راستای تضمین منافع ملت و آحاد مردم با نظم و امنیتی که در رابطه افراد بایکدیگر، دولت نسبت به مردم و مردم نسبت به دولت ایجاد می‌نماید، ضروری و غیر قابل مناقشه است. از این جهت فهم دقیق اصول این قانون و مفاهیم به کار گرفته شده در آن ضرورتی بسیار می‌یابد. چه آنکه هر گونه برداشت و تفسیری که منطبق با روح و متن قانون اساسی نباشد تحقق آرمان نظ...
متن کامل1 v 1 2 5 A ug 1 99 8 Does the Fine Structure Constant Really Vary in Time ?
We discuss how laboratory experiments can be used to place constraints on possible variations of the fine structure constant α in the observationally relevant redshift interval z ≃ 0 − 5, within a rather general theoretical framework. We find a worst case upper limit for ∆α/α of 8 × 10 −6 for z ≤ 5 and ∆α/α of 0.9 × 10 −6 for z ≤ 1.6. The derived limits are at variance with the recent findings ...
متن کاملWhen Variables Don’t Vary Enough
This paper concerns treatment of variables in a dynamic semantics. The main empirical concern will be the interaction of presupposition and quantification, but I will also consider how epistemic modals and quantifiers combine. I will show how these empirical considerations motivate a choice between two styles of quantification. The first of these styles involves treating quantified variables ra...
متن کاملMolecular dating when rates vary.
Molecular-dating techniques potentially enable us to estimate the time of origin of any biological lineage. Such techniques were originally premised on the assumption of a 'molecular clock'; that is, the assumption that genetic change accumulated steadily over time. However, it is becoming increasingly clear that constant rates of molecular evolution might be the exception rather than the rule....
