در این مقاله، برای پیش بینی عملکرد اجکتور یک مدل یک بعدی جدید ارائه شده است. با در نظر گرفتن اختلاط در فشار ثابت، این مدل بر اساس دینامیک گازها و حل معادلات مربوط به بقای جرم، مومنتوم و انرژی، پایه ریزی شده است. این مدل قادر است که نسبت مساحت و نسبت مکش اجکتور را در شرایط مختلف ترمودینامیکی، با دقت بالایی پیش بینی نماید. جهت در نظر گرفتن تلفات ناشی از لزجت سیالات و اختلاط دو جریان، برای بخش های...

Passiflora L. belongs to the family Passifloraceae sensu stricto , and comprises 700–750 species. There are approximately 161 known species of in Brazil, which 153 belong 89 endemic, 83 occur region Atlantic Domain; 40 Rio de Janeiro State (RJ). Using field samplings techniques scientific collection analyses, we present here new geographic records for deidamioides Harms, P. imbeana Sacco, junqu...

Mosaic fate mapping requires first a measurement of the frequency of separation (by genotype) of two structures and then a conversion of this frequency of separation to distance (WYMAN and THOMAS 1982). If the genotype of two structures is visible, the frequency of separation (sturt distance) may be directly obtained. If the genotype is not visible (e.g. , for behavioral foci) then the frequenc...

The International Union for the Conservation of Nature Red List is the most useful database of species that are at risk of extinction worldwide, as it relies on a number of objective criteria and is now widely adopted. The R package red - IUCN Redlisting Tools - performs a number of spatial analyses based on either observed occurrences or estimated ranges. Functions include calculating Extent o...

A Cyber-physical-system (CPS) is a computational system that integrates computing modules with physically distributed dedicated elements such as robotic devices and actuators. The concept is closely related to robotics and real-time (RT) embedded systems. Principally, within a CPS, embedded software modules manage the physical processes by means of feedback loops and continuous computations. It...

ABSTRACT Sinningia rupicola (Gesneriaceae), espécie ameaçada de extinção e classificada como endêmica canga do Quadrilátero Ferrífero é aqui apresentada sob uma abordagem ecológica, baseada na análise dados referentes a registros realizados em duas Reservas Particulares Patrimônio Natural (RPPN) da empresa Vale, situadas no Ferrífero, Estado Minas Gerais, Brasil: Capanema Poço Fundo.
