Countries and cities population data are current between 2015 and 2025, depending on when the last census of the relevant population was made, and some data are based on statistical forecasts. The population of the capitals and the largest cities is without the suburbs. * When you are in the main screen of a country, you can get the following details: - Increased view of the national flag (with 3D touch support) - Increased view of the state coat of arms (with 3D touch support) - Country map and its location in the continent or region; Each map can be zoomed in to improve viewing and get more details. * You may switch between English and Bulgarian languages. *** Това приложение съдържа информация за всички държави - независими или автономни, към края на 2024 година. Навигацията е бърза и лесна. Информацията е концентрирана, изчистена. Приложението ще ви спести ценно време за търсене в интернет и ще ви даде един по-ясен и обобщен вид на информацията за държавите. Търсене може да правите по име или част от име на държава или столица, освен това може да задавате филтър по континент. Информацията може да служи както за бързи справки по всякакъв повод и нужда, така и за обучение на деца, а и на всеки възрастен, който желае да знае повече за държавите по света. Да, това приложение наистина може да замести големите, тежки и обемисти атласи и карти. А най-хубавото е, че то винаги ще е с вас и ще ви даде желаната информация само за няколко секунди! Не без значение е и това, че за да заредите всяка една карта или изображение в приложението, нямате нужда от интернет. Всички ресурси са в приложението, което не бави зареждането им. * Разполагате с някои допълнителни справки като например коя подред е дадена държава според площта на територията й, според населението, брутния вътрешен продукт и други. * Може да се забавлявате с 4 куиза, с които ще тествате и допълвате знанията си по география. * Данните за населението на държавите и градовете са актуални към периода 2010 - 2025, в зависимост от това кога е извършено последното преброяване на съответното население, а някои данни са на база на статистически прогнози. Населението на столиците и на най-големите градове е без предградията. * Когато сте в основния екран на дадена държава, можете да получите следните детайли: - Увеличен изглед на националния флаг (с поддръжка на 3D touch); - Увеличен изглед на държавния герб (с поддръжка на 3D touch); - Карта на държавата и местоположението й в континента или в региона; Всяка карта може да се увеличава (zoom), с цел подобряване на разглеждането и повече детайли. * Избор между български и английски език.

Pocket MRS was designed to be a fast and versatile electronic reference and educational tool for students, medical professionals, researchers and anybody else engaged in the field of in vivo magnetic resonance spectroscopy (MRS). Pocket MRS is a mobile application that offers simple and easy access to simulated spectra from the human brain and its detailed analysis. Spectra available from 0 to 300 ms TE were obtained using realistic quantum mechanical density operator simulations, and then scaled using known concentration, T1 and T2 values across 19 different metabolites and the sum of 10 macromolecules. Spectra can be manipulated with respect to echo time, magnetic field quality and noise levels, providing quick and convenient visualization of the impact of typical experimental conditions on spectral appearance. The app can be a quick digital reference and valuable help for the MRS community when desktop computers and extended MRS software tools are not available.
